Description

The present invention relates to a technique for inspecting characteristics of a feeder that is mounted on a surface mounter and supplies a mounted component.

A plurality of tape feeders that supply chip components using tape as a carrier are mounted on the component supply unit, and components are picked up from a tape feeder (abbreviated as feeder) by a component mounting head and mounted on a substrate such as a printed circuit board. Surface mounters are generally known. In this type of surface mounter (abbreviated as a mounter), mistakes may occur in feeding the tape by the feeder, etc., and mistakes may occur in component adsorption by the head. If such component adsorption mistakes frequently occur, the stable productivity of the substrate is hindered. Therefore, recently, the suction rate of parts is monitored for each feeder, and the feeder whose level of suction has dropped to a certain level is identified and displayed on the monitor, etc., to prompt the operator to perform inspection, adjustment, etc. A mounting machine has been proposed (Patent Document 1). In addition, an apparatus capable of adjusting the feeding accuracy of the tape feeder with a single feeder has been proposed (Patent Document 2).

An outline of a control system of the mounter 1 5 will be described with reference to FIG.

  In the following description, for convenience of explanation, the tape feeder 15 attached to the feeder mounting plate 14 is assumed to be all feeders of the same model.

  As shown in these drawings, the tape feeder 15 includes a microcomputer 40, a feeder-side external communication interface (abbreviated as I / F) 42 for transmitting and receiving data between the mounting machine body 10, and a feeder-side internal communication. An I / F 44 and a display 46 including a small liquid crystal display panel are provided. The microcomputer 40 controls the drive of the tape feeder 15 in an integrated manner, and controls communication between the storage unit 40a (corresponding to the recording unit according to the present invention) for storing various information and the mounting machine body 10. It includes functions such as communication control means 40b. The storage means 40a stores information such as ID information for identifying the tape feeder 15, model (type), and parts. The component information is information such as the type of component supplied by the tape feeder 15 and is written by the operator when the reel 31 is mounted on the tape feeder 15, for example. The type information is information for specifying the model of the tape feeder 15 and corresponds to the width of the usable tape 31 (see FIGS. 12 and 13).

  On the other hand, the mounting machine body 10 includes a board-side external communication I / F 52 that transmits and receives data to and from the tape feeder 15, and a control that identifies and determines the data based on data input from the I / F 52.

  The feeder-side external communication I / F 42 and the board-side external communication I / F 52 are connectors, which are provided on the lower surface of the tape feeder 15 and the upper surface of the feeder mounting plate 14 (upper surface of each feeder mounting position), respectively. It is removable. By attaching the tape feeder 15 to the feeder attachment plate 14, the I / Fs 42 and 52 are connected, and information is transmitted and received between the mounting machine body 10 and the tape feeder 15.

  The control board 50 determines the arrangement position of each tape feeder 15, the supply parts of each tape feeder 15 and the like based on information transmitted from each board-side external communication I / F 52 (information stored in the storage means 40a). The memory 54 stores a microcomputer 54, a main body internal side external communication I / F 56, and the like. The microcomputer 54 includes a storage unit 54a that stores various types of information, a determination unit 54b that determines various types of information, and a communication control unit 54c that performs communication control.

  The control board 50 receives the information transmitted from the tape feeder 15 and stores the received information in the storage unit 54a. At this time, each board-side external communication I / F that has transmitted the information is judged by the discriminating means 54b, whereby the attachment position of each tape feeder 15 is recognized, and this attachment position is also stored in the storage means.

  The storage means 54a stores a data map indicating the types of components, the arrangement positions of parts determined in accordance with the types of substrates P to be mounted, and the rank of the tape feeder 15 that supplies each component. The discriminating means 54b collates this data map with the information of the tape feeder 15 stored in the storage means 54a and the rank of each tape feeder 15 to determine whether an appropriate tape feeder 15 is arranged. It is determined whether or not. The “rank” is a performance index of each tape feeder 15 given based on the characteristic inspection by the characteristic inspection apparatus 2 as will be described in detail later.

  The controller 60 comprehensively controls the mounting operation in the mounting machine. The controller 60 is provided with an external communication I / F 62, and information is transmitted and received between each control board 50 and the controller 60 via the I / F 62 and the external communication I / F 56 inside the main body. ing. Further, the monitor 64, the input device 66, and the external storage device 3 are connected to the controller 60 via the external communication I / F 62.

  The controller 60 further has, as its functional configuration, a data map creation means 61a for creating the data map stored in each control board 50 (storage means 54a), and a rank for checking and specifying the rank of each tape feeder 15. Specifying means 61b.

  Based on the information stored in the external storage device 3, the data map creating means 61 a arranges components according to the board P to be mounted, and ranks (requests) of the tape feeders 15 suitable for supplying each component. The data map is created by determining the rank), and the created data map data is transmitted to each control board 50 and stored in the storage means 54a.

  The outline of the data map creation method is as follows. First, the arrangement position of the component in the feeder installation area 13 of the target board P is determined based on a predetermined optimization method so that the component mounting efficiency becomes higher based on the component mounting position and the number.

  On the other hand, the request rank is determined according to a request rank table stored in the external storage device 3. The request rank table defines conditions such as the type and size of usable parts and the parts that can be used for parts mounted in narrow adjacent positions, for each rank. In addition, the rank (required rank) of the tape feeder 15 suitable for the supply is determined according to the required rank table based on the production conditions of the mounted parts of the board P to be produced. FIG. 7 shows an example of the request rank table. In this example, three ranks “A” to “C” are provided, and the size of usable parts (length dimensions in the X and Y directions with reference to the parts supply time) is determined for each rank. Yes. Therefore, for example, when a component having a length dimension of 0.5 mm in each of the X and Y directions is mounted, the data map creating means 61a determines the required rank of the tape feeder 15 as “B”.

  The request rank table includes stop designation information as shown in FIG. This stop designation information defines a coping method when a tape feeder 15 having a rank different from the required rank defined in the data map is attached in the usability determination process described later. Specific contents will be described together in the description of the availability determination process.

  The rank specifying means 61b specifies the rank of each tape feeder 15 currently attached to the feeder attachment plate 14 from postscript rank information stored in the external storage device 3 based on the ID information.

As shown in FIG. 1, the characteristic inspection apparatus 2 includes an inspection apparatus main body 2a and a data processing apparatus 2b such as a personal computer. This characteristic inspection apparatus 2 inspects the characteristic of each tape feeder 15 mounted on the mounting apparatus 10 in advance. Specifically, the feeding position and feeding speed of the tape 31 are measured by driving the tape feeder 15 alone, and the performance of the tape feeder 15 is evaluated by ranking based on the measurement result.

  The inspection apparatus main body 2a of the characteristic inspection apparatus 2 includes a feeder attachment portion 70 and an imaging unit 72 that images the tape feeder 15 attached thereto. The imaging unit 72 is composed of a CCD camera, an illumination device, and the like. The imaging unit 72 images the component take-out part 33 (the component pocket of the tape 31) of the tape feeder 15 and outputs the image signal to the data processing device 2b. It has become.

  FIG. 8 shows an outline (functional configuration) of the control system of the characteristic inspection apparatus 2.

  As shown in the figure, the characteristic inspection device 2 includes an external communication I / F 81 that transmits and receives data to and from the tape feeder 15 and the external storage device 3 that are attached to the feeder attachment portion 70, and communication control means that performs communication control. 82. Further, as a configuration for executing a predetermined characteristic inspection, the liquid crystal display includes an inspection execution unit 80, an image processing unit 83, a measurement unit 84, an evaluation unit 85, a storage unit 86, and the like, and performs various displays associated with the inspection. A monitor 87 such as a vessel is provided.

  The inspection execution unit 80 controls the characteristic inspection apparatus 2 in an integrated manner, and executes the characteristic inspection process of the tape feeder 15 according to an execution program stored in advance. The feeder attaching portion 70 of the inspection apparatus main body 2a has substantially the same configuration as the feeder attaching plate 14 of the mounting machine main body 10. When the tape feeder 15 is attached to the feeder attaching portion 70, the tape feeder 15 is not shown. The control signal can be transmitted and received between the inspection execution means 80 and the tape feeder 15 through the I / Fs 81 and 42.

The image processing unit 83 performs predetermined processing on the image data output from the imaging unit 72. The measuring means 84 measures the feed speed of the tape 31 based on an output signal from an encoder (not shown) built in the feed motor 34 of the tape feeder 15. The evaluation unit 85 recognizes the component pocket position based on the image of the tape 31 that has been subjected to image processing by the image processing unit 83 and evaluates the performance of the tape feeder 15 based on the recognition result and the measurement result of the measurement unit 84. That is, the above ranking. The storage means 86 stores the position of the component pocket, the measurement result of the tape feed speed , and the like. The storage means 86 stores a rank specifying table necessary for performance evaluation by the evaluation means 85. The monitor 87 displays the result of the evaluation.

  In this embodiment, the imaging unit 72, the measurement unit 84, and the like correspond to the measurement unit according to the present invention, and the evaluation unit 85, the storage unit 86, and the like correspond to the evaluation unit according to the present invention.

  Next, specific contents of the characteristic inspection of the tape feeder 15 by the characteristic inspection apparatus 2 based on the control of the inspection execution unit 80 will be described with reference to the flowcharts of FIGS.

As shown in FIG. 9, the characteristic inspection is performed by measuring the feed position / feed speed of the tape 31 (step S1) and performing rank specifying / updating processing (step S2) based on the result.

[Measure feed position / feed speed ]
The measurement starts when the tape feeder 15 is attached to the inspection apparatus main body 2a and an inspection start operation is performed by an input device provided in the data processing apparatus 2b.

FIG. 10 is a flowchart showing the feed position / feed speed measurement process. In this process, the inspection execution means 80 first sends a feed start command to the tape feeder 15 to drive the tape 31 by one pitch and to cause the measuring means 84 to start measuring the tape feed speed (step). S11, S13). When the tape feeding is completed (YES in step S15), the measurement result by the measuring unit 84 is stored in the storage unit 86 (step S17), and the imaging unit 72 is further driven to image the component take-out unit 33 of the tape feeder 15. . The evaluation means 85 recognizes the feed position (part pocket position) of the tape 31 based on the image data and records the position data in the storage means 86 (steps S19 and S21).

Then, the inspection execution means 80 repeats the processing of steps S11 to S21 for one revolution of the sprocket 35 (NO in step S23), and determines that the feeding speed data and feeding position data for one revolution have been acquired (YES in step S23). ), The measurement process is terminated, and the process proceeds to rank specification / update process.

[Rank identification / update]
FIG. 11 is a flowchart of rank specifying / updating processing.

In this process, the measurement data is read from the storage means 86 to the evaluation means 85, the amount of variation in the X and Y directions of the part pocket position (referred to as feed position accuracy) is obtained, and the average value of the feed speed is obtained (step S31). ).

The evaluation unit 85 further reads the rank specifying table stored in the storage unit 86. FIG. 12 and FIG. 13 are examples of the rank specifying table, and show the rank specifying table having “feed position accuracy” and “feed speed ” as rank specifying elements, respectively.

The evaluation means 85 first determines whether or not the evaluation based on the “feed position accuracy” is necessary, that is, whether or not the rank is specified (step S35 ). This determination is made based on the necessity information for rank specification included in the rank specification table (feed position accuracy; FIG. 12). Specifically, based on the “type” information stored in the storage unit 40a of the tape feeder 15, for example, if the type of the tape feeder 15 is “8 mm”, it is determined that the rank needs to be specified, and “32 mm”. If it is above, it is judged that rank specification is unnecessary.

  If it is determined that the rank needs to be specified, the evaluation unit 85 specifies the rank of the tape feeder 15 based on the feed position accuracy obtained in step S31 and the table (feed position accuracy; FIG. 12). The ranked rank is recorded (steps S37 and S39). For example, when the type of the tape feeder 15 is “8 mm” and the feed position accuracy in the X and Y directions is both less than 0.1 mm, the evaluation unit 85 has rank A of 0.2 mm. Rank B, and if it is 0.5 mm or more, rank C.

Next, the evaluation unit 85 determines whether or not the rank needs to be specified based on the feed speed (step S41). When it is determined that the rank needs to be specified, the rank of the tape feeder 15 is specified and specified based on the feed rate (average value) obtained in step S31 and the table (feed rate ; FIG. 13). The rank is recorded (steps S43 and S45). For example, the evaluation means 85 is rank A when the type of the tape feeder 15 is “8 mm” and the feed speed is less than 8 mm / sec, rank C when the speed is 10 mm / sec or more, and otherwise. Is rank B.

  If it is determined that the rank is not specified in the determinations in steps S35 and S41, the evaluation unit 85 skips each rank specifying process.

  Next, the evaluation means 85 reads out the ranks recorded in steps S39 and S45, specifies the lowest rank among the recorded ranks as the rank of the tape feeder 15 (step S47), and the tape feeder 15 Is sent to the external storage device 3 as rank information in which the ID information and the rank as the evaluation result are associated with each other (step S51). Thereby, a series of characteristic inspection processing by the characteristic inspection apparatus 2 is completed.

  Next, preparation work before starting production of the substrate P in the mounting machine 1 of the mounting system and control by the controller 60 in the production preparation will be described.

  In the mounting machine 1, as a production preparation, a production program for the board P to be produced is read from the external storage device 3, and the width of the conveyor 12 of the mounting machine 1 based on the called production program. Etc. are automatically set. At this stage, each control board 50 stores the data map corresponding to the board P to be produced.

  Then, as a so-called setup operation, an operator prepares a tape feeder 15 for supplying necessary parts to the substrate P to be produced, and the tape feeder 15 is attached to the feeder mounting plate 14 at a position corresponding to the substrate P. It is done. At this time, the operator can display the data map on the monitor 64 by operating the input device 66, and attach the tape feeder 15 while referring to the data map.

  When the tape feeder 15 is attached, component information together with ID information is transmitted from each tape feeder 15 to the mounting machine body 10 through the I / Fs 42 and 52 and stored in the storage means 54a of each control board 50.

  When this preparation is completed, the rank of each tape feeder 15 attached to the feeder attachment plate 14 by the setup operation is specified by the controller 60 (rank specifying means 61b). Specifically, the rank information stored in the external storage device 3 is searched based on the ID information of the tape feeder 15, and the rank of each tape feeder 15 is checked. Thereafter, the use determination process of each tape feeder 15 is executed in each control board 50 (discriminating means 54b).

[Usability determination processing]
FIG. 14 is a flowchart illustrating an example of the availability determination process. When this processing is started, the discrimination means 54b collates the rank information of the first tape feeder 15 stored in the storage means 54a with the requested rank of the data map (steps S51 and S53), and the tape feeder 15 Is matched with the required rank, that is, whether the rank of the tape feeder 15 is equal to or higher than the required rank, and the result is transmitted to the controller 60 (step S55). If it is determined that the required rank is satisfied, the controller 60 performs use permission setting for the tape feeder 15 (step S57), and the process proceeds to step S59.

  On the other hand, when the determination unit 54b determines that the requested rank is not satisfied, the controller 60 reads the stop designation information (step S61) and executes a predetermined process. In the present embodiment, as shown in FIG. 7, when the request rank is “A” as the stop designation information, the operation stop setting is set, and when the request rank is “B”, the warning setting is set. The controller 60 determines the request rank of the tape feeder 15 and determines whether or not the operation stop setting has been made (step S63). When it is determined that the operation stop setting has been made, that is, when the required rank of the tape feeder 15 is “A”, the operation of the mounting machine is stopped and a message to that effect is displayed on the monitor 64 (step S65, S67). For example, as shown in FIG. 15, a message to replace the tape feeder 15 that satisfies the required rank is displayed on the monitor 64. In this case, after the operator replaces the target tape feeder 15 with one that matches the required rank, the mounting machine main body 10 is stopped until the availability determination process is executed again.

  On the other hand, when the operation stop setting is not set (that is, when the warning setting is set), the controller 60 displays a determination request message on whether or not to use the feeder 15 on the monitor 64, and the operator Wait for work execution input (steps S69, S71). When the operator inputs work execution based on the operation of the input device 66, the controller 60 performs use permission setting for the tape feeder 15 (step S57). The stop designation information in the case of the request rank “A” is set as the operation stop setting, and the stop designation information in the case of the request rank “B” is set to the warning setting. Even if the tape feeder 15 is attached, it is considered that there is little influence on the component suction accuracy, etc. However, when the rank C tape feeder 15 is attached to the required rank A, the component suction accuracy is impaired. This is because the possibility is much higher and the risk is greater. In addition, as shown in FIG. 7, the stop designation information is not set for the required rank C. The reason is that if the required rank is “C”, even if the rank A or B tape feeder 15 is installed by mistake, This is because the adsorption accuracy is not impaired.

  Then, it is determined whether or not collation with the required rank has been completed for all tape feeders 15 attached to the feeder attachment plate 14 (step S59). If not completed, the process returns to step S51 to return to the next. The tape feeder 15 is checked against the required rank. On the other hand, if it is determined that collation with the required rank has been completed for all the tape feeders 15, the determination unit 54b ends the usability determination process.

  When the usability determination process is thus completed, the controller 60 starts the mounting operation of the substrate P in accordance with a predetermined mounting program for the substrate P.

As described above, the characteristic inspection apparatus 2 included in the mounting system measures the predetermined parameters related to the component supply performance of the tape feeder 15, that is, the feed position and feed speed of the tape 31, and based on the results. Since the rank of each tape feeder 15 is specified, the characteristics of each tape feeder 15 of the same model can be detected through the rank.

  In the mounting machine 1, the rank (required rank) of the tape feeder 15 suitable for the production of the board P according to the production conditions of the board P, such as the type (size) of the mounted parts, the mounting position (mounting point) of the parts, etc. ), And the tape feeder 15 conforming to the required rank is attached to the feeder mounting plate 14 so that the mounting operation is performed. Therefore, while using a plurality of tape feeders 15 of the same model, It is possible to rationally supply parts by utilizing the characteristics of each feeder 15. That is, when supplying small parts or the like that require the accuracy of the suction position, the high-rank tape feeder 15 with high tape feeding accuracy is used for priority (see FIG. 7), and conversely the accuracy of the suction position. The low-rank tape feeder 15 is used to supply the loose parts, and the same type of feeder 15 is rationally used based on the production conditions of the substrate P. Accordingly, it is possible to effectively reduce the occurrence of troubles such as component adsorption mistakes by the head 19, and it is uniform without distinguishing the characteristics (individual differences) of this type of conventional apparatus, that is, the same type of tape feeder. In comparison with a conventional device used as the same device, a component mounting board with high mounting accuracy can be produced more stably.

  The mounting system described above is an example of a preferred embodiment of a mounting system including the characteristic inspection device 2 according to the present invention. Specific configurations of the mounting machine 1 and the characteristic inspection device 2 as well as the system configuration are as follows. The present invention can be changed as appropriate without departing from the gist of the present invention.

  For example, in the embodiment, the characteristic inspection device 2 is provided separately from the mounting machine 1, but the characteristic inspection device 2 may be integrated into the mounting machine 1. That is, the feeder 15 may be inspected for characteristics while the tape feeder 15 is attached to the feeder attachment plate 14 in the feeder installation region 13. In this case, the functional configuration of the characteristic inspection apparatus 2, that is, the functional configuration of the inspection execution unit 80, the measurement unit 84, the evaluation unit 85, the storage unit 86, and the like is incorporated in the controller 60, and the signal from the encoder of the tape feeder 15 May be received through the I / Fs 42 and 52 and the feeding position of the tape 31 may be imaged using the imaging unit 27 of the head unit 18.

  Further, a part of the feeder installation area 13 of the mounting machine main body 10 is constituted by a batch exchanging carriage, that is, a batch that supports the tape feeder 15 and can detach the feeder 15 from the mounting machine main body 10 in a lump. In the mounting machine 1 including the exchange carriage, the characteristic inspection device 2 may be provided integrally with the collective exchange carriage.

  In the embodiment, the rank information of each tape feeder 15 is configured to be centrally managed by storing the information in the external storage device 3, but of course, the rank information may be stored in each tape feeder 15. Good. In this case, the inspection execution means 80 may be configured to transmit rank information from the characteristic inspection apparatus 2 to the tape feeder 15 and store it in the storage means 40a (corresponding to the writing means according to the present invention). The same applies to the case where the characteristic inspection device 2 is integrally provided in the mounting machine body 10 or the collective exchange cart as described above. Note that when rank information is stored in the tape feeder 15, the mounting machine 1 may be configured to acquire rank information directly from each tape feeder 15 instead of from the external storage device 3 in the above-described usability determination process. .

  In addition, the characteristic inspection apparatus 2 of the embodiment is configured to rank each tape feeder 15 by measuring the feeding position and feeding speed of the tape 31 as predetermined parameters associated with the component supply performance. Of course, parameters other than those described above can be applied.

  In the above embodiment, the application of the present invention has been described by taking as an example the case where the tape feeder 15 is used as the feeder. However, the present invention naturally includes a stick feeder or a bulk for supplying parts individually without using the tape as a carrier. The present invention is also applicable when using a feeder such as a feeder.
