Description

  The present invention relates to a manual mounting apparatus for a board component for manually mounting a board component on a printed board.

In component mounting for printed circuit boards, a component supply jig called a component cassette having an ID in which component specific information is recorded and a device for reading the substrate specific information ID are provided. Automatic devices that associate information on a one-to-one basis are already known. The automatic equipment is always equipped with jigs for automatically supplying parts, and the take-out position and mounting position are programmed by the NC program, so it is easy to associate each piece of unique information simply by adding an ID reading device. It is.
However, since automatic assembly is difficult due to restrictions such as the shape of the parts, there are cases where retrofitted parts are left by manual work, and they are assembled by manual insertion.
In the process of manually inserting components, the component supply method is not fixed, and the mounting order is random because people mount the components, so it was not easy to identify the mounted components and mounting positions. .

As a conventional technique for easily performing a manual insertion operation, for example, the following manual insertion instruction device is disclosed.
That is, a plurality of parts boxes for storing parts are provided with a part take-out detecting means for detecting whether or not a part is taken out, while a procedure registration control means and a procedure instruction control means are provided. First, in the teaching mode, the part take-out detection is performed. Each time the removal of the component is detected by the means, the procedure registration control means associates the data of the component insertion position on the printed wiring board, the component number of the component, and the component insertion order number with each other in the memory. Next, in the insertion mode, each time the component removal detection unit detects the removal of the component, the procedure instruction control unit performs the insertion position indicator and the component instruction based on each data stored in the memory. Are sequentially driven, and an insertion procedure is automatically instructed (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 7-7289 (page 4, FIGS. 1 and 2)

  The conventional manual insertion instruction device can reliably set the part insertion procedure and perform the insertion work when mounting the part on the printed circuit board by manual insertion. However, the specific information between the inserted component and the printed circuit board has not been associated. This unique information includes, for example, the manufacturer and lot number. If it is intended to manage such unique information, the conventional apparatus has to take a method of recording and managing each unique information of the board and the component every time the component is inserted, and it takes a lot of time for the recording work. Needed to reduce productivity.

  The present invention has been made to solve the above-described problems, and can manually manage the specific information of the component to be manually attached and the specific information of the printed circuit board, thereby improving the quality of component mounting. An object is to obtain a manual mounting apparatus for board components.

  A manual mounting apparatus for board components according to the present invention is based on a plurality of component boxes for storing a plurality of board components to be mounted on a printed board for each type, board-specific information and board-part specific information. In a manual mounting apparatus for a board component that includes a control unit for instructing the mounting position of the component, and manually mounting the board component taken out from the component box to the component insertion position of the printed circuit board, Component ID registering means for registering and registering the component ID associated with the specific information of the board component to be stored in the component box or the control unit, and storing the registered component ID in the control unit It is comprised as follows.

  According to the manual mounting device for board components of the present invention, the component ID registration means for registering the component box in association with the component ID of the board component registers the component ID associated with the specific information of the board component to be accommodated, Since it is configured so as to be stored in the control unit, it becomes possible to manage the specific information of the board components mounted manually in association with the specific information of the printed circuit board, and to improve the mounting quality.

Embodiment 1 FIG.
1 is a block diagram of a manual mounting apparatus for board components according to Embodiment 1 of the present invention, and FIG. 2 is a block diagram thereof. The configuration will be described below with reference to FIGS.
As shown in FIG. 1, a board component 2 that is manually mounted on a printed circuit board 1 is accommodated in a component box 3 for each type of board component 2.
Specific information (hereinafter referred to as a component ID) of the component is given to the accommodated component.
The part ID includes, for example, the type of part, part diagram number, manufacturer, manufacturing lot, input serial number N0. Etc. Input serial number Is a number that can be distinguished into units for handling things, such as the order of parts and the lot of parts.
On the other hand, a box ID 3a is assigned to the parts box 3 as unique information of the parts box 3 itself. The box ID 3a is box specific information recorded on the IC tag, a box ID number recorded on a bar code, a QR code, or the like.

  In order to associate the component box 3 with the accommodated board component 2, a component ID registration means 4 is provided in the front part of the component box 3 to which the box ID 3 a is attached. The component ID registration means 4 is configured by a generally known non-contact read / write device. A specific registration method will be described later.

  The plurality of component boxes 3 in which the substrate components 2 are accommodated are set at the component supply position of the component supply shelf 6. A part ID reading means 7 is provided in front of the box ID 3a assigned to the set parts box 3, and a part take-out position detecting means 8 is provided on the side where the parts of the part box 3 are taken out. . The component ID reading means 7 is configured by a generally known non-contact reading device. Moreover, the component extraction position detection means 8 is comprised with the photoelectric sensor which consists of a light projection part and a light-receiving part, for example.

  On the other hand, the printed circuit board 1 is mounted on the work table 9 and performs a mounting operation. The printed circuit board 1 also includes a circuit board ID 1a which is made up of an IC tag, a bar code, or the like and in which board specific information is registered. For example, board unique information such as a board drawing number, a unit number, and a manufacturing number is associated with the board ID 1a and registered. A board ID reading means 10 is provided at a position facing the board ID 1 a when the printed board 1 is set on the work table 9. The substrate ID reading means 10 is also constituted by a generally known non-contact reading device.

Further, on the side of the printed circuit board 1 opposite to the side on which the circuit board component 2 is inserted (back surface side), the circuit board component 2 is a predetermined part of the printed circuit board 1 in the process of manually mounting the circuit board component 2 on the circuit board 1. Insertion presence / absence detection means 11 is provided for detecting whether or not it has been inserted at the position. The insertion presence / absence detecting means 11 is constituted by, for example, an image recognition device having a CCD.
Further, the control unit 5 is provided with an alarm device 12 so that an alarm can be issued in conjunction with the operations of the component extraction position detection means 8 and the insertion presence / absence detection means 11. The control unit 5 includes an input device 13 having a display unit (not shown). The control unit 5 is configured as shown in FIG. 2, and will be described together with the following flowchart.

FIG. 3 is a flowchart showing the component specific information registration process, and FIG. 4 is a flowchart showing the component attachment verification process and the board / component specific information association registration process. The operation will be described according to each flowchart with reference to FIG. 1 and FIG. First, the flowchart of FIG. 3 will be described.
First, after the board component 2 is accommodated in the component box 3, it is set to the component ID writing position (step 31). The component specific information of the board component 2 housed in the component box 3 is input from the input device 13 of the control unit 5 (step 32). As described above, the component specific information includes, for example, the component type, component diagram number, manufacturer, manufacturing lot, input serial number N0. Etc. The input result is displayed on the display screen (step 33), and the input result is confirmed (step 34). If the input result is OK, the component ID registration means 4 registers the component ID in the box ID 3a made up of an IC tag or the like provided in the component box 3 (step 35). If the component box ID 3a is a barcode, the code is read and associated with the component ID, and is registered and stored in the unique information storage device 22 by the unique information registration control means 21.

  Usually, since there are a plurality of types of board components that are manually mounted, the above-described registration operation is performed for different types of component boxes 3 for each type. Thus, the plurality of component boxes 3 are in a state in which the box ID and the component ID of the accommodated board component 2 are associated and registered. What should be noted here is that the manufacturing lot and the input serial number are registered as the part-specific information to be registered. It is to include up to the level of. For example, even if the board parts 2 have the same part diagram number, those having different production lots are not handled as the same parts.

Next, the plurality of component boxes 3 in which the board components 2 are accommodated are set at any of a plurality of installation positions on the component supply shelf 6 of the apparatus (step 36).
Since the component ID of the accommodated board component 2 is registered in each box ID 3a of the component box 3 set at the installation position of the component supply shelf, the component ID reading means 7 provided on the front surface of each component box 3 is registered. Thus, the component ID is read and automatically transmitted to the unique information recording control means 23 of the control unit 5 in association with the set position of the component box 3. The unique information recording control means 23 registers such information in the searchable unique information storage device 24 (step 37). As a result, it is possible to know what board component is housed in the component box at which position.
When the box ID 3a is a barcode, the registration information registered in the control unit in advance in association with the barcode is referred to.

Next, the flowchart of FIG. 4 will be described.
First, the printed circuit board 1 is set on the work table 9 (step 41). On the printed circuit board 1, board components already mounted automatically are mounted. Further, since the printed board 1 is provided with a board ID 1a (this is necessary for automatic mounting) that is associated with board specific information in advance, the board ID 1a of the board 1 is read by the board ID reading means 10. Obtained (step 42), transmitted to the unique information recording control means 23 of the control unit 5, and refers to the substrate configuration information from the database previously input to the control unit 5 (step 43).

Next, when the operator takes out the substrate component 2 from one of the plurality of component boxes 3 set on the component supply shelf 6 (step 44), the extraction position of the substrate component 2 is detected by the component extraction position detection means 8. (Step 45) and transmitted to the control unit 5. As a result, the component unique information and the component box installation position are associated with each other, and the component unique information (component diagram number, etc.) of the taken-out board component 2 is referred to (step 46). For example, if the extraction position detected by the component extraction position detection means 8 is the position A, the board component 2 associated with the component ID read by the component ID reading means 7 at the position A has been extracted. I understand.
At this time, if a board component that should not be mounted on the board is found by collating the parts information, an alarm is issued from the alarm device 12 (step 48) to notify the operator of the error. Specifically, for example, if the unique information of the prohibited component is registered in advance, and a result of collation with the unique information of the board component 2 taken out matches with the unique information of the prohibited component, an alarm is issued. Good.

The control unit 5 searches the insertion position based on the part number and mounting position data to be mounted on the printed circuit board 1 registered in advance, and instructs the operator on the insertion position of the extracted board component 2 (step 49). ). Regarding the specification and instruction of the insertion position, for example, a known technique such as issuing an instruction using an insertion position indicator as shown in the patent document described in the background section may be applied. . This part does not necessarily have to be instructed from the control unit 5.
The operator inserts the board component 2 into a predetermined position on the printed board 1 in accordance with the instruction (step 50).

  Then, based on the insertion position data, in order to see whether or not a predetermined part has been inserted at a predetermined position, the insertion presence / absence detecting means 11 detects the part insertion position (step 51), and the information is stored in the control unit 5 This is transmitted to the insertion position detection control means 25. The insertion position detection control means 25 collates with the data registered in the insertion position storage device 26 (step 52). If the insertion position detection control means 25 is inserted at the wrong position, a warning is immediately issued from the alarm device 12. (Step 53), the operator is notified.

When all the board components 2 are inserted into the printed circuit board 1 and the mounting operation is completed, the component-specific information referenced from the component ID and all the board-specific information referenced from the board ID are associated with each other as a unique information database that can be searched for information. It is registered in the unique information recording device 24 (step 54). Thereby, after the assembly of the printed circuit board 1 is completed, the unique information for each circuit board component constituting the printed circuit board 1, that is, the part number, the manufacturer, the production lot, the input serial number, etc. can be easily searched at any time. It becomes possible.
In the registration stage of step 54, for example, if the operator and the work day are also registered, the history of those can also be searched. The storage devices 22, 24, and 26 may be configured by the same storage device in hardware.

Also in the conventional manual insertion instruction device, since the insertion position is searched and instructed based on the part number of the insertion part and the specific information of the board, it is possible to associate the board with the insertion part. However, when searching for the history of mounted parts on a completed printed circuit board later, it is easy to track the history of the part manufacturer and the manufacturing lot even though the part number can identify the part type. I couldn't.
In the case of the present embodiment, the manufacturer, the manufacturing lot, the input serial number, and the operator are also registered as the part-specific information of the manually mounted parts. Searchable. In recent years, due to an increase in quality awareness, there is a case where a user of a printed circuit board requests a history of parts with a fine mesh, but such a request can be easily met.

  As described above, according to the board component manual mounting apparatus of the present embodiment, there is a part ID registration unit for registering the part box and the part ID of the board part in association with each other. Since the component ID associated with the information is registered in the component box or the control unit, and the registered component ID is stored in the control unit, the specific information of the board component mounted manually is the specific information of the printed circuit board. Can be managed in a one-to-one relationship with each other, and the mounting quality can be improved.

  Further, since the component specific information includes the production lot and / or the input serial number of the substrate component, the history of the printed circuit board can be managed with a fine management mesh.

  In addition, there are component ID reading means for reading the component ID when a plurality of component boxes are set at the component supply position, and component extraction position detecting means for detecting the extraction position when the board component is extracted from the component box. In addition, since the configuration is such that the board component extracted from the read component ID and the detected extraction position is specified and stored in the control unit, the board component to be mounted can be reliably detected, It is possible to warn of installation mistakes by collating.

  In addition, it has a board ID reading means for reading the board ID given to the printed board in association with the unique information of the printed board, and the control unit performs a search based on the board ID read by the board ID reading means. Since the insertion position of the board component taken out is instructed and the specific information of the board component mounted in accordance with the instruction is registered in the control unit in association with the specific information of the printed circuit board. Each unique information with the board component can be automatically associated. Therefore, after completion of the assembly of the printed circuit board, it is possible to easily retrieve the history of the specific information (for example, including the production lot, the input serial number, etc.) for each circuit board component constituting the printed circuit board. .

  Furthermore, an insertion presence / absence detecting means for detecting whether or not the board component is inserted into the insertion position is provided, and an alarm is issued when the board component is not properly inserted. Can be prevented, and the mounting quality of the board components can be improved.
