Description

Component mounter

The present invention relates to a component mounter having a function of instructing an operator of an empty slot for setting a feeder.

Conventionally, as described in Patent Document 1 (Japanese Patent No. 4425529), for the purpose of improving the operating rate of a component mounting machine, the same parts as other feeders are provided in an empty slot of a feeder set base of the component mounting machine. When a feeder runs out of components while the component mounter is in operation, switch to a spare feeder that supplies the same component as that component feeder and mount the component. There is something that has been continued.

Japanese Patent No. 4425529

The spare feeder can be set in any empty slot of the feeder set base. However, when the worker sets the spare feeder in any empty slot, the following problems occur.

The feeder width varies depending on the size of the component to be supplied (the width of the component supply tape), and there is a wide feeder having a feeder width larger than one slot pitch in addition to a narrow feeder in which the feeder width fits within one slot pitch. When a plurality of feeders having different feeder widths are arranged side by side and set in an empty slot, the number of slots occupied by the plurality of feeders varies depending on the arrangement order of the feeders.

As shown in FIG. 5, the number of slots occupied by the left and right adjacent feeders varies depending on the width of each feeder. FIG. 5 shows the number of occupied slots where the width of the feeders adjacent to the left and right is W8 (8 mm), W12 (12 mm), and W44 (44 mm). When the width of the feeder on the left is W8, the feeder on the right When the width of W8 is W8, the number of occupied slots is 1P (1 slot pitch), and when the width of the feeder on the right is W12, the number of occupied slots is 2P (2 slots) and the width of the feeder on the right is When is W44, the number of occupied slots is 3P (3 slot pitch). Also, when the width of the left adjacent feeder is W12, when the width of the right adjacent feeder is W8, the occupied slot number is 2P, and when the width of the right adjacent feeder is W12, the occupied slot number is 2P ( When the width of the feeder on the right is W44, the number of occupied slots is 4P. Also, when the width of the feeder on the left is W44, when the width of the feeder on the right is W8, the number of occupied slots is 4P, and when the width of the feeder on the right is W12, the number of occupied slots is 4P. When the width of the feeder on the right is W44, the number of occupied slots is 5P.

For example, when four feeders are set in the order of W8 → W44 → W12 → W8, the total occupied slot number of the four feeders is 3P + 4P + 2P = 9P from the feeder mounting table of FIG. 9 slots are occupied.

On the other hand, when four feeders are set in the order of W8 → W12 → W44 → W8, the total occupied slot number of the four feeders is 2P + 4P + 4P = 10P from the feeder mounting table of FIG. 10 slots are occupied.

Therefore, even if the combinations of the widths of the four feeders are the same, the latter is occupied by one extra slot depending on the arrangement order of the four feeders. Since the number of slots in the feeder set base of one component mounter is fixed, in order to increase the number of feeders to be set, the feeder arrangement order must be set so that the number of slots occupied by the plurality of feeders to be set is minimized. Conventionally, the operator arbitrarily determines the feeder arrangement order, so the number of occupied slots is not necessarily minimized. For this reason, the number of feeders that can be set on one feeder set base may be reduced depending on the order in which the feeders are arbitrarily determined by the operator, so that the feeder array can be improved to improve production efficiency and work efficiency. It was difficult to optimize the order.

Therefore, the problem to be solved by the present invention is to provide a component mounting machine capable of optimizing the feeder arrangement order so that the number of feeders that can be set on one feeder set base can be increased.

In order to solve the above problems, the present invention provides a feeder set base provided with a plurality of slots in which a plurality of feeders are set side by side, and a component supplied from the feeder set in the slot of the feeder set base. When a plurality of feeders having different feeder widths are set side by side in empty slots of the feeder set base, the number of slots occupied by the plurality of feeders is the number of slots of the plurality of feeders. In a component mounter that differs depending on the arrangement order, the component mounting machine includes instruction means for instructing an operator to set a feeder in an empty slot of the feeder set base, and the instruction means includes a plurality of feeders in the empty slot of the feeder set base. When instructing to set, the number of slots occupied by the plurality of feeders is In display and / or audio empty slots to set each feeder so that small is obtained so as to instruct the operator.

In this configuration, since the operator is instructed of empty slots for setting each feeder so that the number of slots occupied by a plurality of feeders is minimized, the feeder arrangement order can be optimized, and one feeder set The number of feeders that can be set on the stand can be increased, and production efficiency and work efficiency can be improved.

A component mounting machine configured to move a component sucked by a suction nozzle from its suction position to an imaging position, pick up an image with an imaging device, recognize the image of the component, and then mount the component on a circuit board. When applying the present invention, when instructing to set a plurality of feeders in empty slots of a feeder set base, a combination of feeder arrangement orders that minimizes the number of slots occupied by the plurality of feeders is selected, and In the combination of feeder arrangement orders, it is preferable to indicate an empty slot for setting each feeder so that the moving distance or moving time of the suction nozzle from the suction position to the imaging position is the shortest. In this way, since the moving distance or moving time of the suction nozzle from the suction position to the imaging position is minimized, the cycle time can be shortened and the productivity can be improved.

In addition, when the present invention is applied to a component mounting machine in which an imaging device that captures an image of a component sucked by the suction nozzle is held by a mounting head that holds the suction nozzle, a plurality of feeders are provided in empty slots of the feeder set base. When instructing to set, a combination of feeder arrangement orders that minimizes the number of slots occupied by the plurality of feeders is selected, and among the combinations of feeder arrangement orders, from the suction position to the mounting position of the circuit board The operator may be instructed of an empty slot for setting each feeder so that the moving distance or moving time of the suction nozzle is minimized. In this way, since the moving distance or moving time of the suction nozzle from the suction position to the mounting position is minimized, the cycle time can be shortened and the productivity can be improved.

In addition, when one of the multiple feeders set in the slot of the feeder set base runs out of parts, it is configured to switch to a spare feeder that supplies the same parts as the parts that have run out of parts and to continue mounting the parts. When the present invention is applied to the mounted component mounter, it is instructed to set a plurality of spare feeders that supply the same components as the plurality of feeders having a short time until the components run out in empty slots of the feeder set base. At this time, the operator may be instructed of an empty slot for setting each spare feeder so that the number of slots occupied by the plurality of spare feeders is minimized. In this way, the arrangement order of a plurality of spare feeders can be optimized, the number of spare feeders that can be set on one feeder set base can be increased, and production efficiency and work efficiency can be improved.

In the present invention, when an instruction of an empty slot for setting a feeder is displayed, it may be displayed on any display device as long as the display device is installed in a place where an operator can see and check, for example, a component You may display on any of the display apparatus of the host computer which manages production of a mounting line, the display apparatus of a component mounting machine, the display screen of the portable terminal which an operator carries.

Further, a display unit for displaying an empty slot for instructing to set a feeder may be provided on the feeder set base. In this way, it becomes easy for the operator to know the empty slot for setting the feeder, and an operation mistake for setting the feeder in the wrong slot different from the instruction can be prevented.

An embodiment in which the mode for carrying out the present invention is applied to a modular component mounting system will be described.
First, the configuration of the modular component mounting system will be described with reference to FIG.

A plurality of mounting machine modules 12 (component mounting machines) are arranged on the base table 11 of the module type component mounting system so as to be replaceable and adjacent to each other in the circuit board transport direction (X direction). Each mounting machine module 12 was adsorbed on a main body bed 13 by a feeder set base 21 (see FIGS. 2 and 3) for setting the feeder 14, a conveyor 15 for conveying the circuit board 10, and an adsorption nozzle (not shown). An image pickup device 16 (parts camera) for picking up images of a component is mounted and mounted with a mounting head 17 holding one or more suction nozzles, an image pickup device (mark camera) for picking up a reference position mark on the circuit board 10, and the like. ing. The mounting head 17 is moved in the XY direction by an XY moving mechanism (not shown), and performs a component suction operation and a component mounting operation. A display device 19 such as a liquid crystal display or a CRT and an operation unit 20 such as operation keys are provided on the front surface of the upper frame 18.

Each mounting machine module 12 transports the circuit board 10 transported from the upstream mounting machine module 12 to a predetermined position by the conveyor 15, and clamps and positions the circuit board 10 with a clamp mechanism (not shown). At the same time, the parts supplied by the feeder 14 are sucked by the suction nozzle of the mounting head 17, moved from the suction position to the imaging position, imaged by the imaging device 16, and the parts are image-recognized, and then on the conveyor 15. Mounted on the circuit board 10. Here, the image recognition of the component is performed to determine the component suction posture and the presence / absence of the component, or to measure the shift amount of the component suction position to correct the mounting position.

As shown in FIG. 2, the upper surface of the feeder set base 21 is provided with a plurality of inverted T-groove slots 22 having a predetermined pitch for vertically supporting the plurality of feeders 14. By inserting a guide rail (not shown) having an inverted T-shaped cross section provided in the slot 22 into the slot 22 from the front side, the feeder 14 is supported on the feeder set base 21 in a vertically placed state, and provided on the feeder 14. The clamp member (not shown) fitted into the clamp groove 23 of the feeder set base 21 and presses the feeder 14 in the insertion direction (connector 24 side of the feeder set base 21) to perform clamping. Is positioned on the feeder set base 21 in the front-rear direction, and a connector (not shown) on the front end surface of the feeder 14 is connected to the feeder set base 21. Insert the connector 24 is adapted to be connected. Thereby, the control device (not shown) of the mounting machine module 12 and the control unit (not shown) of each feeder 14 are connected by the signal line via the connector 24, and the component supply operation of each feeder 14 is performed. In addition to being controlled, the number of remaining parts of each feeder 14 is managed to detect a part breakage.

Further, in the vicinity of the insertion slot of each slot 22 of the feeder set base 21, a slot number display unit 25 (display unit) for displaying the slot number and an empty slot 22 for setting the feeder 14 are instructed to the operator. A set instruction lamp 26 is provided. In place of the set instruction lamp 26, an illumination light source is provided inside the slot number display section 25 of each slot 22 to illuminate the slot number display section 25 of the slot 22 instructing the setting of the feeder 14, thereby providing a feeder. The operator may be instructed to the empty slot 22 in which 14 is set.

Incidentally, FIG. 3 shows a state where a plurality of feeders 14 are set on the feeder set base 21, and S1 to S18 indicate slot numbers. The feeder 14 is set in the slot 22 of S1 to S9, and the slot 22 of S10 to S18 is an empty slot. The arrangement sequence of the feeders 14 set in the slots 22 of S1 to S9 is designated by a production job (production program).

In this embodiment, spare feeders for supplying the same parts as the feeders 14 set in the slots 22 (S1 to S9 in FIG. 3) of the feeder set base 21 are set in the empty slots 22 (S10 to S18 in FIG. 3). When one of the feeders 14 is out of components during the operation of the mounting machine module 12, the component mounting is continued by switching to a spare feeder that supplies the same components as the feeder 14 out of components. . In order to realize such switching to the spare feeder, the control device (not shown) of the mounting machine module 12 has a short time until the parts of the feeder 14 set in the slot 22 of the feeder set base 21 run out. 14 functions as an instruction means for instructing the operator by display and / or voice so as to set a spare feeder that supplies the same parts as the spare slot 14 of the feeder set base 21.

As described above, even when a plurality of spare feeders having different feeder widths are arranged and set in the empty slot 22 as described above, the operator arbitrarily determines the order of arranging the spare feeders. Is not necessarily minimized. For this reason, the number of spare feeders that can be set on one feeder set base 21 may be reduced depending on the order in which spare feeders are arbitrarily determined by the operator, thereby improving production efficiency and work efficiency. As such, it is difficult to optimize the order of the spare feeders.

Therefore, in this embodiment, the control device of the mounting machine module 12 sets a plurality of spare feeders in the empty slot 22 of the feeder set base 21 by executing the spare feeder arrangement order instruction program of FIG. When instructing, a combination that minimizes the number of slots occupied by the plurality of spare feeders is selected, and the moving distance (or movement) of the suction nozzle from the component suction position to the mounting position of the circuit board 10 in the combination is selected. It functions as an instruction means for displaying the empty slot 22 for setting a plurality of spare feeders and instructing the operator by voice. Hereinafter, the processing flow of the spare feeder arrangement order instruction program of FIG. 4 will be described.

The spare feeder arrangement order instructing program in FIG. 4 is in a state in which a plurality of empty slots 22 (S10 to S18 in FIG. 3) for setting a predetermined number of spare feeders exist in the slots 22 of the feeder set base 21. It is executed automatically or manually by the operator. When this program is started, first, in step 101, a predetermined number (a plurality) of feeders 14 having a short time until parts run out are selected from the set feeders 14.

Thereafter, the process proceeds to step 102, and the number of occupied slots for setting the predetermined number of spare feeders is determined by the arrangement order of the predetermined number of spare feeders that supply the same parts as the predetermined number of feeders 14 having a short time until the parts run out. Determine whether it changes. As a result, if it is determined that the number of occupied slots changes depending on the arrangement order of the spare feeders, the process proceeds to step 103, and the combination of the arrangement order of spare feeders with the smallest number of occupied slots is referred to the feeder mounting table in FIG. And select.

Thereafter, the process proceeds to step 104, and the moving distance (or moving time) of the suction nozzle from the picking position of the component to the mounting position of the circuit board 10 is the shortest among the combinations of the selected order of the spare feeders selected. The arrangement order of a predetermined number of spare feeders is selected. Thereafter, the process proceeds to step 106, where the number (position) of the empty slot 22 in which the spare feeder is set is displayed and / or instructed by voice. Here, the display may be displayed on any display device as long as it is installed in a place that can be seen and checked by the operator. For example, the host computer that manages the production of the modular component mounting system May be displayed on any of the display device (not shown), the display device 19 of the mounting machine module 12, the display screen of a portable terminal carried by the worker, and the like. Further, the set instruction lamp 26 of the slot number display section 25 of each slot 22 may be turned on to instruct the number of the empty slot 22 in which the spare feeder is set.

On the other hand, if it is determined in step 102 described above that the number of occupied slots does not change according to the arrangement order of the predetermined number of spare feeders, the process proceeds to step 105, and the suction nozzles from the component suction position to the mounting position of the circuit board 10 The arrangement order of a predetermined number of spare feeders with the shortest moving distance (or moving time) is selected. Thereafter, the process proceeds to step 106, where the number (position) of the empty slot 22 in which the spare feeder is set is displayed and / or instructed by voice.

According to the present embodiment described above, the empty slot 22 for setting a plurality of spare feeders is displayed and / or instructed to the operator by voice so that the number of slots occupied by the plurality of spare feeders is minimized. The arrangement order of spare feeders can be optimized, the number of spare feeders that can be set on one feeder set base 21 can be increased, and production efficiency and work efficiency can be improved.

In addition, in this embodiment, when instructing to set a plurality of spare feeders in the empty slot 22 of the feeder set base 21, the spare feeder that minimizes the number of slots occupied by the plurality of spare feeders is used. An empty slot that selects a combination of arrangement orders and sets a plurality of spare feeders so that the movement distance (or movement time) of the adsorption nozzle from the component adsorption position to the imaging position is the shortest among the arrangement order combinations. Since 22 is instructed to the operator, the cycle time can be shortened and the productivity can be improved.

In the above embodiment, the arrangement order of the feeders 14 (S1 to S9 in FIG. 3) to be used first is specified by the production job, and the arrangement order of the spare feeders is determined so that the number of occupied slots is minimized. However, the arrangement order of the feeders 14 (S1 to S9 in FIG. 3) to be used first may be determined so that the number of occupied slots is minimized. Also in this case, when instructing to set the plurality of feeders 14 in the slots of the feeder set base 21, a combination of feeder arrangement orders that minimizes the number of slots occupied by the plurality of feeders 14 is selected, and the feeder arrangement The operator may be instructed of an empty slot 22 in which each feeder 14 is set so that the moving distance (or moving time) of the suction nozzle from the suction position to the imaging position is the shortest in the combination of orders.

Further, in the above-described embodiment, the component sucked by the suction nozzle is moved from the suction position to the image pickup position, picked up by the image pickup device 16, and the component is image-recognized, and then the component is mounted on the circuit board 10. However, the present invention may be applied to a component mounting machine in which a mounting head that holds a suction nozzle holds an imaging device that captures an image of a component sucked by the suction nozzle. In this configuration, since the imaging device is held by the mounting head, it is possible to image the component sucked by the suction nozzle without moving the mounting head to the imaging position. Therefore, when the present invention is applied to the component mounting machine having the above configuration, when instructing to set a plurality of feeders in empty slots of the feeder set base, the number of slots occupied by the plurality of feeders is minimized. A space for selecting a combination of feeder arrangement orders, and setting each feeder so that the moving distance or moving time of the suction nozzle from the picking position of the component to the mounting position of the circuit board 10 becomes the shortest among the combinations of the feeder arranging orders. The slot may be instructed to the worker. In this way, since the moving distance or moving time of the suction nozzle from the suction position to the mounting position is minimized, the cycle time can be shortened and the productivity can be improved.

The present invention is not limited to the above-described embodiments. For example, the configuration of the mounter module 12 (component mounter) may be changed as appropriate, and various changes may be made without departing from the scope of the invention. Needless to say, this can be done.
