Description

  The present invention relates to a screen printing apparatus for printing cream solder, conductive paste, or the like on a substrate as a pretreatment for mounting a component on a substrate such as a printed wiring board (PWB).

  A screen printing device is built into a printed circuit board (PCB) production line, prints conductive paste on the substrate conveyed from the upstream side, and sends it to the component mounting device on the downstream side. is there.

  This type of screen printing apparatus is configured to receive substrates one by one in the apparatus, perform printing using one screen mask on which one printing pattern is formed, and send it out to a component mounting apparatus. It is common.

  Recently, however, as disclosed in Patent Document 1, the apparatus includes two transport lines and one screen mask on which two print patterns corresponding to these transport lines are formed, and is provided along each transport line. It has been proposed to perform printing using a different printing pattern for each conveyance line while individually receiving a substrate, and then individually sending it out to a component mounting apparatus.

  However, the screen printing apparatus of Patent Document 1 is based on the premise that the substrate is carried into and out of the two conveyance lines as described above, and the pitch on the substrate carry-in side and the pitch on the substrate carry-out side of these carry lines are Since they are the same, there are the following problems.

  That is, the printed circuit board production line is configured in various forms to increase productivity. For example, a single transport type device (referred to as one system device) having one substrate transport line and two substrate transports. A screen printing apparatus as described in Patent Document 1 is installed between a dual-conveying type component mounting apparatus or a single-conveying type two component mounting apparatus (collectively referred to as two-system apparatuses) having lines in parallel. On the contrary, there is a case where the same screen printing apparatus is desired to be installed between the two upstream apparatuses and the one component mounting apparatus. In other words, the printed circuit board is sequentially transferred from the upstream apparatus of one system to the two component mounting apparatuses while appropriately printing different patterns, or conversely, the printed circuit board is transferred from the upstream apparatus of the two systems. There are cases where it is desired to print different patterns and send them to a single component mounting apparatus.

  However, in the conventional apparatus described in Patent Document 1 in which it is necessary to carry in / out the substrate along two transfer lines, it is arranged between one upstream apparatus and two system component mounting apparatuses by itself. Therefore, in actual operation, for distributing the substrate transported from the upstream device to each substrate transport line of the screen printing device between the upstream device and the screen printing device. It is necessary to attach a sorting device. Similarly, when the conventional apparatus described in Patent Document 1 is arranged between two upstream apparatuses and one downstream apparatus (component mounting apparatus), it is between the screen printing apparatus and the component mounting apparatus. It is necessary to provide a switching device for switching the substrate receiving source.

  Further, since the conventional apparatus has the same pitch on the board carry-in side and the pitch on the board carry-out side of the transfer line as described above, between the two upstream apparatuses and the two downstream apparatuses (component mounting apparatuses). Even if it is installed at the same time, if the line-to-line pitch of each board transfer line of the upstream apparatus and the line-to-line pitch of each board transfer line of the component mounting apparatus are different, the upstream apparatus and the component mounting apparatus It is impossible to place them alone, and it is necessary to install a relay device that relays the conveyance of the board between the upstream device and the screen printing device, or between the screen printing device and the component mounting device. It becomes.

  However, in such a line configuration in which ancillary equipment such as a sorting device and a switching device is provided in addition to the screen printing device, it is not desirable in order to save space and reduce the cost of the printed circuit board manufacturing equipment. There is room for.

  The present invention has been made in view of such circumstances, and in a screen printing apparatus provided with a single screen mask including two printing patterns, a system of one system can be used without requiring additional equipment such as a sorting apparatus.

  That is, when printing is performed using the first printing pattern 211 of the mask 21, the squeegee 26 of the first squeegee unit 24A is set at a predetermined angle with respect to the surface (horizontal plane) of the substrate W, and printing work is performed. The first squeegee unit 24A is driven in the X-axis direction in this state. On the other hand, when printing is performed using the second printing pattern 212 of the mask 21, the squeegee 26 of the second squeegee unit 24B is set at a predetermined angle with respect to the surface of the substrate W and disposed at the printing work position. In this state, the second squeegee unit 24B is configured to be driven in the X-axis direction.

  The imaging unit 28 is for recognizing an image of the relative positional relationship between the mask 21 and the substrate W, and is a mask for imaging a plurality of marks such as marks and symbols written on the lower surface of the mask 21 from below. A recognition camera 28a and a substrate recognition camera 28b that images a plurality of marks such as marks and symbols of the substrate W supported by the substrate support device 10 from above are provided. The imaging unit 28 is connected to an XY robot (not shown) so as to be two-dimensionally movable in the horizontal direction. Based on the control of the XY robot by a control device described later (before printing) Each mark is imaged by being interposed between the mask 21 and the substrate W (before the mask is overlaid).

  The printing apparatus 1A includes a control device (not shown) having a CPU or the like as a component (corresponding to the control means of the present invention). The substrate support device 10, the squeegee units 24A and 24B, and the imaging unit 28 are provided. The control device performs a series of printing processing operations such as receiving a substrate W carried in from the substrate carry-in portions En1 and En2, printing on the substrate W, and carrying out the substrate W from the substrate carry-out portion Ex. It is designed to be controlled comprehensively.

  Next, a printing operation of the printing apparatus 1A based on the control of the control apparatus will be described with reference to FIGS.

  FIG. 1 schematically shows a state at a specific point in time of a printing operation continuously performed in the printing apparatus A1, and specifically, a second pattern among the two printing patterns 211 and 212 of the mask 21. The state immediately after printing of the board | substrate W using 212 is shown.

  From such a state shown in FIG. 1, first, the substrate support device 10 moves to the delivery position, that is, the conveyor pair 12 corresponds to the substrate carry-out portion Ex. Then, after the clamped state of the substrate W is released, the printed substrate W is fed out from the substrate support device 10 by driving the conveyor pair 12, the conveyor pair on the base 2 and the conveyor SM, and the substrate unloading unit Ex Are carried out to the component mounting apparatus M (FIG. 4A).

  When the unloading of the substrate W is completed, the substrate support device 10 receives the subsequent substrate W in the first or second receiving position, that is, the position where the conveyor pair 12 corresponds to the first substrate loading portion En1 or the second substrate loading portion En2. Move to. Thereby, the substrate W carried in from the first substrate carry-in part En1 or the second substrate carry-in part En2 is received on the conveyor pair 12 of the substrate support apparatus 10. For example, as shown in FIG. 4B, the substrate W carried in from the first substrate carry-in portion En1 is received on the conveyor pair 12, and is clamped at a predetermined position.

  When the clamping of the substrate W is completed, the substrate W is arranged at a position below the print pattern to be printed out of the two print patterns 211 and 212 of the mask 21 as shown in FIG. The substrate W can be disposed at a position below any of the print patterns 211 and 212 of the mask 21 by the movement of the substrate support apparatus 10 in the Y-axis direction. However, in the illustrated example, the substrate W is disposed at a position below the first pattern 211. ing.

  Prior to printing, the imaging unit 28 advances between a substrate W and the mask 21 from a predetermined retracted position (position shown in FIG. 3), images each marker on the substrate W and the mask 21, and then moves to the retracted position. Moving. As a result, the respective positions of the substrate W and the mask 21 are image-recognized, and based on these recognition results, the positional deviation between the mask 21 and the substrate W is obtained, and the X-axis, Y-axis, and R-axis directions corresponding to the positional deviation Correction values (ΔX, ΔY, ΔR) are obtained. Such recognition processing and calculation of correction values are performed by the control device based on images captured by the cameras 28a and 28b.

  When the recognition of the substrate W or the like is completed, the substrate W is overlaid on the mask 21. At this time, based on the correction values (ΔX, ΔY, ΔR), the substrate support device 10 is driven and controlled in the Y-axis direction, and the conveyor pair 12 is driven and controlled in the X-axis and R-axis directions by the moving mechanism of the conveyor pair 12. Thus, the mask 21 is properly stacked on the substrate W.

  When the mounting of the substrate W on the mask 21 is completed, the one corresponding to the print patterns 211 and 212 to be printed out of the two squeegee units 24A and 24B is activated, thereby printing on the substrate W. . In the example of FIG. 4C, after the squeegee 26 of the first squeegee unit 24A moves downward from the retracted height position to the printing work height position, the entire squeegee unit 40 including the squeegee 42 is moved in the X-axis direction. Printing is performed on the substrate W by moving.

  When printing is completed, the conveyor pair 12 is reset to a predetermined home position. That is, when the conveyor pair 12 moves in the X axis, Y axis, and R axis directions by driving the moving mechanism of the conveyor pair 12, the clamp mechanism 14 fixedly supported by a frame (not shown) of the conveyor pair 12 is used. The clamped substrate W is released from the mask 21, the clamp of the clamp mechanism 14 is released, and the substrate W is placed on the conveyor pair 12 by the lowering of the backup mechanism. It is arranged at a position where the substrate W can be transferred between CL1, CL2 and SM.

  When the printing of the substrate W is completed in this way, the substrate support device 10 moves to the delivery position, and the printed substrate W is sent out from the substrate support device 10 by driving the conveyor pair 12, and then from the substrate carry-out portion Ex to the component mounting device M. It is carried out. Thereafter, printing is performed using either one of the two print patterns 211 and 212 of the mask 21 while the substrate W carried from the first substrate carry-in portion En1 or the second substrate carry-in portion En2 is received by the substrate support device 10. It is carried out to the component mounting apparatus M from the board carry-out part Ex.

  According to the printing apparatus 1A described above, printing can be performed using the single mask 21 including the two printing patterns 211 and 212 as in the conventional apparatus (the screen printing apparatus disclosed in Patent Document 1 of the background art). In addition, printing can be carried out while accepting the plate W from the two loaders L1 and L2 by the printing apparatus 1A alone, and the printing apparatus 1A can carry it out to the one component mounting apparatus M. Accordingly, while the printing apparatus 1A is interposed between the two upstream apparatuses (loaders L1, L2) and the one downstream apparatus (component mounting apparatus M), the incidental equipment (switching apparatus) as in the conventional apparatus is provided. ) Is not necessary, and thus the production line can be made compact.

  In the printing apparatus 1A, an example in which two different types of print patterns 211 and 212 are formed as the mask 21 has been described. However, the print patterns 211 and 212 may be the same type of pattern ( The same applies to the following second to sixth embodiments).

  Next, a second embodiment of the screen printing apparatus according to the present invention will be described with reference to FIG.

  FIG. 5 schematically shows a screen printing apparatus 1B (hereinafter abbreviated as printing apparatus 1B) according to the second embodiment in a plan view. The printing apparatus 1B according to the second embodiment is a modification of the printing apparatus 1A according to the first embodiment, and differs in configuration from the printing apparatus 1A according to the first embodiment in the following points.

After printing, the substrate support device 10 is arranged at the first delivery position or the second delivery position, so that the substrate W is transferred from the first substrate carry-out portion Ex1 to the first component mounting apparatus M1 or the second substrate carry-out portion Ex2. From the component mounting apparatus M2.

  According to the printing apparatus 1B of the second embodiment, in addition to being able to perform printing using the mask 21 including the two printing patterns 211 and 212, the printing apparatus 1B alone accepts the substrate W from the single loader L. However, printing can be carried out and carried out to the two component mounting apparatuses M1 and M2. Therefore, according to the printing apparatus 1B, an auxiliary apparatus such as a conventional apparatus is interposed between the upstream apparatus (loader L1) of one system and the downstream apparatuses (component mounting apparatuses M1 and M2) of two systems. Equipment (sorting device) is unnecessary, and the production line can be configured compactly.

  Next, a third embodiment of the screen printing apparatus according to the present invention will be described with reference to FIG.

  FIG. 6 schematically shows a screen printing apparatus 1C (hereinafter abbreviated as printing apparatus 1C) according to the third embodiment in a plan view. The printing apparatus 1C according to the third embodiment is a modification of the printing apparatus 1A according to the first embodiment, and differs in configuration from the printing apparatus 1A according to the first embodiment in the following points.

In the illustrated example, the first loader L1 is provided. The substrate W fed out from the first substrate carry-in section En1 is loaded into the apparatus, the substrate W fed out from the second loader L2 is loaded into the apparatus from the second substrate carry-in section En2, and the printed substrate W is loaded into the first substrate. It is configured to selectively carry out from the carry-out part Ex1 to the first component mounting apparatus M1 or from the second substrate carry-out part Ex2 to the second component mounting apparatus M2. Then, the substrate support apparatus 10 further moves to a first sending position where the printed substrate W can be carried out from the first substrate carry-out portion Ex1, and to a second sending position where the printed substrate W can be carried out from the second substrate carry-out portion Ex2. The printing apparatus 1 </ b> C is different in configuration from the printing apparatus 1 </ b> A of the first embodiment in these respects. The substrate carry-out portions Ex1 and Ex2 are provided at positions between both substrate carry-in portions En1 and En2 in the Y-axis direction. In other words, the substrate carry-out portions Ex1 and Ex2 are provided at an arrangement pitch Pt2 (Pt2 <Pt1) different from the arrangement pitch Pt1 of both substrate carry-in portions En1 and En2.

Therefore, according to this printing apparatus 1C, it is a case where it arrange | positions between two upstream apparatuses (loader L1, L2) and two downstream apparatuses (component mounting apparatus M1, M2), and upstream. Even if the pitch between the board transfer lines of the side device differs from the pitch between the board transfer lines of the downstream device, the conventional incidental equipment (relay device) is not required, and it is manufactured by this. The line can be made compact.

  Next, a screen printing apparatus according to a fourth embodiment of the present invention will be described with reference to FIGS.

  FIG. 7 schematically shows a screen printing apparatus 1D (hereinafter abbreviated as printing apparatus 1D) according to the fourth embodiment in a plan view. The printing apparatus 1D according to the fourth embodiment is a modification of the printing apparatus 1A according to the first embodiment, and differs in configuration from the printing apparatus 1A according to the first embodiment in the following points.

  That is, this printing apparatus 1D has two substrate support devices 10A and 10B (referred to as a first substrate support device 10A and a second substrate support device 10B) as substrate support devices. These substrate support devices 10A and 10B have the same configuration, are supported on a common fixed rail 3 installed on the base 2, and are individually Y-axis driven by a screw feed mechanism using a motor as a drive source. It is driven in the direction. The first substrate support apparatus 10A moves between the receiving position (first receiving position) where the substrate W carried in from the first substrate carry-in portion En1 can be received and the delivery position, while The substrate support apparatus 10B moves between a receiving position (second receiving position) where the substrate W carried in from the second substrate carry-in portion En2 can be received and the delivery position. Therefore, in this printing apparatus 1D, the substrate W supported by the first substrate support apparatus 10A can be printed only by the first pattern 211 of the two print patterns 211 and 212 of the mask 21, while the second For the substrate W supported by the substrate support apparatus 10B, only printing by the second pattern 212 is possible.

  In the printing apparatus 1C, it is possible to send the substrate W from the substrate support device 10B (or 10A) on the other side to the substrate carry-out portion Ex while the substrate is being received by the substrate support device 10A (or 10B) on the one side. In other words, as shown in the same figure, for example, as shown in the same figure, the two substrate carry-in portions En1 and En2 are set to be Y so that the substrate support devices 10A and 10B can be simultaneously arranged at the first or second receiving position and the sending position. It is provided at a position outside the mask 21 in the axial direction.

  In the printing apparatus 1D, as shown in the figure, the first substrate support device 10A is disposed below the mask 21, and the substrate W supported by the first substrate support device 10A is located with respect to the first pattern 211. In a state of being positioned, the mask 21 is overlaid and printing is performed. During this printing, the substrate W on the conveyor pair CL2 is received and clamped from the second substrate carry-in portion En2 to the second substrate support device 10B at the first receiving position.

  Thus, the printing of the substrate W supported by the first substrate support apparatus 10A while the first substrate support apparatus 10A sequentially moves from the first receiving position, the lower position of the mask 21 (first pattern 211), and the delivery position. While the operations of unloading the substrate W and receiving the subsequent substrate W are sequentially performed, the second substrate support device 10B has the second receiving position, the mask 21 (second pattern 212) with a certain time difference from the operation. Printing of the substrate W supported by the second substrate support apparatus 10B while sequentially moving to the lower position and the delivery position (FIG. 8B), carrying out the substrate W, and receiving the subsequent substrate W (FIGS. 7 and 8). (A)) is performed sequentially.

  In the printing apparatus 1D of the fourth embodiment, similarly to the printing apparatus 1A of the first embodiment, the printing apparatus 1D alone performs printing while receiving the substrate W from the two upstream apparatuses (loaders L1, L2). Can be carried out to a downstream apparatus (component mounting apparatus M) of one system.

  In addition, according to the printing apparatus 1D, since the printing is performed while the substrates W are alternately received by the two substrate support apparatuses 10A and 10B, the printing is performed as compared with the printing apparatus 1A of the first embodiment. After the finished substrate W is carried out, printing of the subsequent substrate W can be started in a shorter time. Therefore, according to the printing apparatus 1D of the fourth embodiment, the production line can be configured compactly while the printing apparatus 1 is interposed between the two upstream apparatuses and the one downstream apparatus. In addition to the operational effects similar to those of the printing apparatus 1A of the first embodiment, it is possible to enjoy the operational effect that the throughput can be improved.

  Although not particularly mentioned in the above description, the imaging unit 28 is common to both the substrate support devices 10A and 10B, and the substrate W is disposed in a state where each of the substrate support devices 10A and 10B is disposed below the mask 21. And the mask 21 (the first pattern 211 or the second pattern 212), each marker is imaged. In this printing apparatus 1D, when the substrate support device 10A (or 10B) on one side is disposed at a position below the mask 21, the substrate on the other side is usually provided as shown in FIGS. 7 and 8B. The support device 10B (or 10A) is disposed at the receiving position, and therefore, the other substrate support device 10B (or 10A) does not interfere with the sign image pickup operation by the image pickup unit 28.

  Next, a screen printing apparatus according to a fifth embodiment of the present invention will be described with reference to FIGS.

The printing apparatus 1D carries the substrate W fed out from one loader L into the apparatus from the board carry-in section En, and the printed board W is transferred from the first board carry-out section Ex1 to the first component mounting apparatus M1. The board unloading unit Ex2 is configured to be unloaded to the second component mounting apparatus M2.

  The substrate carry-in portion En is provided in a line in the X-axis direction with respect to the first substrate carry-out portion Ex1, in other words, at the same position as the first substrate carry-out portion Ex1 in the Y-axis direction.

  Then, the first substrate support apparatus 10A can receive the substrate W carried in from the substrate carry-in unit En and can operate the work position (position shown in the figure; the printed substrate W can be carried out from the first substrate carry-out unit Ex1; The second substrate support device 10B is provided with a substrate carry-in portion, while being movably provided between the receiving position and the first sending position of the present invention) and a standby position located on the front side of the apparatus (downward in the figure). A receiving position (corresponding to the receiving position of the present invention) capable of receiving the substrate W carried from En and a sending position (to the second sending position of the present invention) capable of sending the printed substrate W to the second substrate unloading section Ex2. Equivalent). In addition, although the said work position in 10 A of 1st board | substrate support devices and the receiving position in 10B of 2nd board | substrate support apparatuses are the same positions, in the description of this embodiment, it distinguishes on the wording.

  The mask 21 is held so that the first pattern 211 of the two print patterns 211 and 212 is positioned at the work position (receiving position). Further, the Y-axis direction of each print pattern 211, 212 is related to the configuration of each substrate support apparatus 10A, 10B so that printing can be performed while the substrate W is simultaneously positioned with respect to each print pattern 211, 212. An interval is set.

  In the printing apparatus 1E, the printing of the substrate W and the unloading of the substrate W after printing are performed in parallel with respect to each of the substrate support devices 10A and 10B. That is, in this printing apparatus 1A, as shown in the figure, the first substrate support device 10A is carried in from the substrate carry-in portion En in a state where it is disposed at the work position (the receiving position and the first sending position). The substrate W is received by the first substrate support apparatus 10A. At this time, the preceding printed substrate W is unloaded from the first substrate unloading section Ex1 to the first component mounting apparatus M1 while being sent out from the first substrate support apparatus 10A. At almost the same time, the preceding printed board W is carried out from the second board carrying-out section Ex2 to the second component mounting apparatus M2 while being sent out from the second board supporting apparatus 10B.

  When the reception of the substrate W to the first substrate support apparatus 10A is completed and the delivery of the preceding substrate W is completed, the first substrate support apparatus 10A is arranged at the standby position as shown in FIG. On the other hand, the second substrate support device 10B is disposed at the receiving position, and the substrate W is received by the second substrate support device 10B in this state.

  When the reception of the substrate W to the second substrate support apparatus 10B is completed, the second substrate support apparatus 10B is disposed below the mask 21 (second pattern 212) and the first substrate support apparatus 10A is set to the mask 21 ( 10 (b), the substrate W of the first substrate support apparatus 10A is changed to the first pattern 211, and the substrate W of the second substrate support apparatus 10B is changed to be lower than the first pattern 211). Each of the markers is imaged by the imaging unit 28 after being positioned on the second pattern 212, and the position of each substrate is corrected by the calculated correction amount. The printing of the substrate W is performed almost simultaneously. Note that imaging of each marker by the imaging unit 28 is performed simultaneously for each substrate W. That is, the imaging unit 28 is between the substrate W of the first substrate support apparatus 10A and the mask 21 (first pattern 211) and between the substrate W of the second substrate support apparatus 10B and the mask 21 (second pattern 212). By continuously moving, the signs of the substrates W and the signs of the masks 21 (print patterns 211 and 212) are continuously imaged.

  When printing is completed, the first substrate support device 10A is arranged at the work position, and the substrate W after printing is sent out to the first substrate carry-out portion Ex1, while the subsequent substrate W is transferred from the substrate carry-out portion Ex to the first substrate support device. While being accepted by 10A, the second substrate support device 10B is arranged at the delivery position, and the printed substrate W is delivered to the second substrate carry-out part Ex2 (see FIG. 9).

  After that, the printing of the substrate W and the unloading of the substrate W after printing are performed substantially in parallel on each of the substrate support devices 10A and 10B.

  According to the printing apparatus 1E of the fifth embodiment as described above, the printing apparatus 1E alone performs printing while receiving the substrate W from the upstream apparatus (loader L) of one system, and performs the downstream apparatus (component mounting apparatus) of two systems.

While the operation of unloading the substrate W and the operation of receiving the subsequent substrate W are sequentially performed, the second substrate support device 10B moves below the second receiving position, the mask 21 (second pattern 212) with a certain time difference from the operation. The printing of the substrate W supported by the second substrate support device 10B (FIG. 12B), the unloading of the substrate W, and the receiving operation of the subsequent substrate W (FIG. 11) are sequentially performed while sequentially moving to the position and the delivery position. .

  According to the printing apparatus 1F of the sixth embodiment as described above, the printing apparatus 1F alone performs printing while receiving the substrate W from the two loaders L1 and L2, and the pitch of the conveyor pairs CL1 and CL2 of these loaders L1 and L2 The substrate W can be carried out to the conveyor pair SM1, SM2 of the component mounting apparatuses M1, M2 installed at a pitch (Pt2) different from (Pt1). Therefore, according to this printing apparatus 1F, each of the upstream apparatuses (loaders L1, L2) and the downstream apparatuses (component mounting apparatuses M1, M2) of the two systems A printing apparatus 1C according to the third embodiment in which the production line can be configured compactly while being arranged between the substrate transport lines having different pitches between the substrate transport lines and the pitches of the substrate transport lines of the downstream apparatus. The same effects as (see FIG. 6) can be obtained. In addition, according to the printing apparatus 1D, as described above, since the substrates W are alternately received by the two substrate supporting apparatuses 10A and 10B, printing is performed and carried out, so that the substrate is compared with the printing apparatus 1C of the third embodiment. There is an advantage that the throughput of W can be improved.

  By the way, the above-described printing apparatuses 1A to 1F are exemplifications of preferred embodiments of the screen printing apparatus according to the present invention, and the specific configuration thereof can be appropriately changed without departing from the gist of the present invention.

  For example, in the printing apparatuses 1D to 1F of the fourth to sixth embodiments, the first pattern 211 of the two printing patterns 211 and 212 of the mask 21 is used for the substrate W supported by the first substrate support apparatus 10A. While printing is performed, the substrate W supported by the second substrate support device 10B is configured to perform printing using the second pattern 212, but the substrate supported by any of the substrate support devices 10A and 10B. Also for W, printing may be possible by arbitrarily using two print patterns 211 and 212. In this case, for example, in the case of the printing apparatus 1D of the fourth embodiment, the second substrate support apparatus 10B is positioned outside the print execution unit 20 when the first substrate support apparatus 10A is positioned on the second pattern 212 (FIG. 7). The first substrate support device 10A is retracted to a position outside the print execution unit 20 (lower side in FIG. 7) when the second substrate support device 10B is positioned on the first pattern 211. You just have to do it. The same applies to the other printing apparatuses 1E and 1F.

  Further, in the printing apparatus 1D of the fourth embodiment and the printing apparatus 1F of the sixth embodiment, each of the substrates W supported by both the substrate support apparatuses 10A and 10B is set in the same manner as the printing apparatus 1E of the fifth embodiment. You may comprise so that it can print in the state positioned simultaneously with respect to the printing patterns 211 and 212. FIG. That is, the arrangement pitch of the two print patterns 211 and 212 is increased to such an extent that the two substrate support apparatuses 10A and 10B do not interfere with each other even if they are positioned below the print patterns 211 and 212, respectively.

  Furthermore, in the printing apparatus 1F according to the sixth embodiment, the arrangement pitch (Pt2) of the component mounting apparatuses M1 and M2 is made as small as possible (for example, the same as or more than the arrangement pitch of the two print patterns 211 and 212). It can also be made smaller). In this case, printing and substrate unloading as shown in FIG. 12A cannot be performed simultaneously. For example, printing on the substrate W on the substrate support device 10A overlaid on the print pattern 211 is possible. During the period during which the substrate W on the substrate support device 10A after printing is unloaded from the first substrate unloading portion Ex1, the substrate W is received from the second substrate loading portion En2 to the substrate support device 10B, and printing is performed. During printing on the substrate W on the substrate support device 10B overlaid on the pattern 212 and during a period during which the substrate W on the substrate support device 10B after printing is unloaded from the second substrate carry-out portion Ex2, the first substrate carry-in portion The substrate W can be received from the En1 to the substrate support apparatus 10A. That is, printing or post-printing of the substrate W can be performed while the substrate is being carried in, and the throughput of the substrate W can be improved.
