[0031]
FIG. 4 is a block diagram showing a control system of the surface mounter. As shown in this figure, the surface mounter has a control device 30 for controlling the mounting operation and the like.
[0032]
The control device 30 includes a well-known CPU that executes logical operations, a ROM that stores various programs for controlling the CPU in advance, a RAM that temporarily stores various data during operation of the device, and the like. The functional configuration includes a main control means 31, a storage means 32 (feeder related information storage means), and a removal feeder specifying means 33. The component supply unit 31 includes a display means 34 (notification means such as a CRT). ), An input means 35 such as a keyboard, a receiving unit controller 36 and the like are connected. In this figure, only the functional configuration directly related to the present invention is shown in the functional configuration of the control device 30, and other functional configurations are omitted.
[0033]
The main control means 31 controls the operation of the surface mounter in an integrated manner, and controls the drive of the servo motors 9 and 11 to operate the head unit 5 and the like in accordance with a prestored mounting program. It is. In particular, during the mounting process, information of the wireless tag 21 of each tape feeder 4 attached to the component supply unit 3 is read by controlling the receiving unit controller 36, and the component supply unit is based on the read information. 3 recognizes the type and arrangement of the tape feeder 4 attached to 3. The receiving unit controller 36 controls the power supply to the circuit incorporated in the antenna substrate 22 and reads and controls the information stored in the wireless tag 21.
[0034]
The storage unit 32 stores information necessary for the mounting process of the printed circuit board P in advance, and the mounting program and the like are stored in the storage unit 32. The mounting program also includes feeder information corresponding to the type of the printed circuit board P, that is, information on the type and arrangement of the tape feeder 4 used in each type.
[0035]
The removal feeder specifying means 33 is a tape feeder 4 that is removed from the component supply unit 3 based on an instruction from an operator or an external instruction from an external personal computer or a remote person via the Internet at the time of post-replacement work performed when changing the type of the printed circuit board P. Is specified. The identification is given to each tape feeder 4 in the type and arrangement of the tape feeder 4 recognized by the main control means 31 based on the information stored in the wireless tag 21, that is, in the example shown in FIG. (1) to (6) shown in FIG. 6 (a) and the size information of each tape feeder 4 comprising the size of the positioning pin 17 from the center of the positioning pin 17 on both sides in the width direction (FIG. 6 (a)). In the state where the positioning pin 17 is fitted in the positioning hole 18, information indicating each space occupied by the tape feeder 4 on both sides in the X-axis direction) and the positioning hole 17 in which the positioning pin 17 of the tape feeder 4 is located. The tape feeder 4 corresponding to the printed circuit board P after the product type switching, that is, the positional information on whether or not it is fitted and the information stored in the storage means 32 In the example shown in FIG. 6B, the identification number assigned to each tape feeder 4 ((3), (4), (7) to ▲ shown in FIG. 6 (b)). 9 ▼) and the position information of the position of the positioning pin 17 of the tape feeder 4 and the size information of each tape feeder 4 having the respective sizes in the width direction from the center of the positioning pin 17 and the positioning pin 17 of the tape feeder 4 The result is temporarily stored in the storage means 32 or a storage means (not shown) in the specifying means 33 and then output to the main control means 31. When the removal feeder specifying means 33 specifies the tape feeder 4 to be removed, the main control means 31 outputs a control signal to the display means 34 to notify the operator of the tape feeder 4.
[0036]
Here, the removal target feeder specifying process by the control device 30 will be described with reference to the flowchart of FIG.
[0037]
This process is executed by the operator performing a predetermined input operation via the input means 35 or taking in an external instruction input. When this process is started, first, information on the type and arrangement of the tape feeder 4 currently attached to the component supply unit 3 is read out to the removal feeder specifying means 33, and the tape feeder 4 after the type switching is changed. Information on the type and arrangement is read to the removal feeder specifying means 33 (steps S1, S2). At this time, information recognized by the main control means 31 by reading the wireless tag 21 is read as information regarding the current attachment state of the tape feeder 4 in the component supply unit 3.
[0038]
In step S3, the feeder counter is set to an initial value “1”, and based on the comparison of the information read in steps S1 and S2, the process starts with the smallest feeder identification number in the current feeder arrangement information (see FIG. In the example shown in FIG. 6 (a), the identification number is {circle over (1)} and starts from n = 1). In step S4, the tape feeder 4 with the current feeder identification number n is the same after the product changeover. It is determined whether or not the position is used as it is. Here, in the case of YES, the process proceeds to step S5, while in the case of NO, the process proceeds to step S7.
[0039]
In step S7, from the position information and size information of the tape feeder 4 whose current identification number is n, it is determined whether or not there is a tape feeder 4 after product switching that interferes with the tape feeder 4, and all the tapes after product switching. The inspection is performed by comparing the position information of the feeder 4 with the size information. Alternatively, the interference check is performed on the tape feeder 4 after the product changeover having the position information of the tape feeder 4 with the current identification number n and the position information close to a predetermined range. If it is determined that there is an interfering object (YES in step S7), the process proceeds to step S8, and the identification number and position information of the tape feeder 4 are stored in the storage device or storage means 32 not shown. Stored in the area. Note that if the tape feeder 4 with the current identification number n is used after switching the product type but is used at a position different from the current one, it is determined YES in step S7 and the process proceeds to step S8. The identification number and position information of the tape feeder 4 are stored in the storage device or the like.
[0040]
On the other hand, if it is determined in step S7 that there is no interference, the process proceeds to step S5, where it is determined whether n matches the number N having the highest feeder identification number.
[0041]
If it is determined that n is smaller than N, 1 is added to n in step S9 to make a new n (however, if there is a missing number in the feeder identification number of the current feeder) In S9, the next largest feeder identification number is set to n). On the other hand, if it is determined that n matches the largest number N of the current feeder identification number, the process proceeds to step S6 and stored in a storage area provided in the storage device or storage means 32 (not shown). Information, that is, the identification number and position information of the tape feeder 4 to be removed is displayed by the display means 34. This is the end of this flowchart. As shown in FIG. 1, a red LED 50 may be arranged on the base immediately in front of the component supply unit 3 so as to correspond to each tape feeder 4 to serve as the display unit 34. Thereby, the tape feeder 4 to be removed can be instructed more easily.
[0042]
According to the above surface mounter, during the mounting process, the printed circuit board P is carried along the conveyor 2 to a predetermined mounting work position (position shown in FIG. 1) and positioned. Then, the head unit 5 moves to the component supply unit 3, and a desired component is adsorbed and taken out from the tape feeder 4 arranged in the component supply unit 3 by the mounting head 13. At this time, the head unit 5 is driven and controlled based on the mounting program stored in the storage unit 32 and information such as the arrangement of the tape feeder 4 recognized based on the reading of the wireless tag 21, so that the mounted component Is taken out from the tape feeder 4 efficiently and accurately. In this case, if possible, a plurality of components are simultaneously sucked and taken out by the plurality of mounting heads 13.
[0043]
When the removal of the components is completed, the head unit 5 moves onto the printed circuit board P, and the mounting head 13 is moved up and down while sequentially placing the components attracted by the mounting heads 13 above a predetermined mounting position. As a result, it is mounted on the printed circuit board P.
[0044]
Then, the head unit 5 repeatedly picks and mounts components while moving between the component supply unit 3 and the printed circuit board P. When all the components are finally mounted, the printed circuit board P is moved to the mounting work position. Then, it is carried out to the next process and a series of mounting operations is completed.
[0045]
When the mounting operation of the same type of printed circuit board P is completed in this way, the setup change operation for the next product type, that is, the type and arrangement of the tape feeder 4 corresponding to the product type after changing the tape feeder 4 of the component supply unit 3. Work to change to. At this time, when the operator performs a predetermined input operation via the input means 35, the feeder 4 to be removed is specified and displayed from the tape feeders 4 currently attached to the component supply unit 3 as described above. It is displayed on the means 34. Therefore, the operator can simply and quickly perform the setup change work by simply removing the feeder 4 according to this display and installing a new feeder 4 at that position.
[0046]
In particular, in this surface mounter, since the tape feeder 4 to be removed is specified according to the procedure (flowchart) shown in FIG. 5, the number of tape feeders 4 to be removed can be minimized. Can be done efficiently. That is, in this surface mounter, not all tape feeders 4 that are currently installed that are not used after product type switching are specified as removal targets, but are not shown in FIG. 5 (steps S4, S7, S8). As shown in Fig. 5), only the feeder 4 at a position that needs to be replaced with another type of feeder 4 and the feeder 4 at a position that physically interferes with the adjacent feeder 4 after switching the product type are specified as the removal target. Then, even if the feeder 4 is not used after the product type changeover, the one that does not interfere with the feeder 4 after the product type change is left as it is.
[0047]
Therefore, it becomes possible to deal with a new type of printed circuit board P by simply replacing the necessary minimum feeder 4, and therefore, it is possible to quickly respond to the change of the type of board and to reduce the operator's work load. become able to.
[0048]
For example, as shown in FIG. 6 (a), when the tape feeders (1) to (6) are attached to the component supply unit, this is changed to the attachment state as shown in FIG. Consider the case. In this case, conventionally, as shown in FIG. 7A (left drawing), first, all the feeders (1), (2), (5), (6)) that are not required after the product changeover are removed and replaced with a new one. The feeders (7) to (9) were attached. On the other hand, according to the above embodiment, as shown in FIG. 7 (b), after switching the product type, only those that interfere with new feeders (7) to (9) ((5) (6)). Even if it is removed, even if it is an unnecessary feeder, the one that does not get in the way ((1) (2)) is left as it is. Therefore, according to the said embodiment, it becomes possible to reduce the time and labor required for the removal | desorption of only 2 feeders compared with the past.
[0049]
Further, in this surface mounter, the type and arrangement of the tape feeder 4 that is actually attached to the component supply unit 3 by reading the information provided with the wireless tag 21 on the tape feeder 4 as described above. Be recognized. Since the feeder 4 to be removed is identified based on the recognition result, the feeder 4 to be removed is accurately identified even when the operator changes the feeder arrangement by manual operation. can do. Therefore, there is also an advantage that the setup change operation can be performed more accurately.
[0050]
The surface mounter described above and the specific procedure of the feeder adopted in the surface mounter are one embodiment of the surface mounter and feeder replacement method according to the present invention, and the specific configuration and The method can be appropriately changed without departing from the gist of the present invention. For example, the following aspects can also be taken.
[0051]
In the embodiment, while the wireless tag 21 is provided on the tape feeder 4, the antenna board 22 having the antenna coil is provided on the feeder mounting plate 16, and the type and arrangement of the tape feeder 4 are recognized by reading the information of the wireless tag 21. However, the feeder to be removed is specified by using the result. For example, a configuration not using the communication system as described above may be used (the antenna substrate 22 and the receiver controller 36 are omitted in FIG. 4). It is also possible to adopt a configuration as described above). In this case, in step S1 of FIG. 5, information on the current arrangement of the tape feeder 4 and the like is acquired from the mounting program stored in the storage means 32, and the feeder 4 to be removed is specified based on this information. Good.
[0052]
In this case, for example, when the arrangement of some of the feeders is changed by the operator, the arrangement becomes different from the arrangement stored in the production program, and as a result, the feeder 4 to be removed may not be accurately identified. It is done. Therefore, for example, an irregular information storage means 37 as shown by a broken line in FIG. 4 is provided, and the operator uses the input means 35 in advance to provide the irregular information storage means 37 using the changed type and arrangement of the tape feeder 4 as irregular information. 37, and information on the current attachment state of the tape feeder 4 based on the mounting program stored in the storage means 32 and the information stored in the irregular information storage means 37 in step S1 of FIG. And the feeder 4 to be removed may be specified based on this information. According to this, it becomes possible to accurately specify the feeder 4 to be removed. The irregular information storage unit 37 may be configured as a part of the storage unit 34 by storing irregular information in a specific memory area in the display unit 34.
[0053]
The information input to the irregular information storage means 37 is not limited to the input means 35 as described above. For example, a bar code on which identification information or the like is recorded is recorded on each tape feeder 4, and the bar code is recorded. Information may be input by reading with a reader. In this case, a two-dimensional code or the like may be used in addition to the barcode.
[0054]
Moreover, in the said embodiment, although the tape feeder 4 is mounted in the components supply part 3, you may make it mount other feeders, such as a bulk feeder, naturally. Moreover, you may make it mount both feeders together.
[0055]
In the above-described embodiment, the mounting program is stored in the storage unit 32 in the control device 30. However, the mounting program may be stored in a storage unit (not shown) provided outside to control the mounting operation from the outside. . That is, when a mounting line is constituted by a plurality of surface mounting machines, printing machines, dispensers, etc., there is also a way to centrally control the operation of each machine with a remote control device.
[0056]
【The invention's effect】
As described above, in the present invention, the types and arrangements of the feeders in the component supply unit before and after the board type switching are compared, and the feeder attached to the component supply unit before the board type switching is compared. Of these, feeders that are not used after product changeover and need to be replaced with other types of feeders when changing the product type of the substrate, or only feeders that interfere with adjacent feeders after product changeover are notified of removal. As a result, it is possible to respond to a new product type by simply replacing the minimum necessary feeders, so that it is possible to quickly perform the feeder replacement operation when changing the product type of the substrate, and to reduce the work burden on the operator at that time. Will be able to.
