DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed circuit board assembling work support system, and more particularly to a printed circuit board assembling work supporting system for supporting a manual work process in assembling a printed circuit board.

[0002]

[Prior Art] QFP (Quad Flat Package), SOP (Small Ou)
With the provision of so-called surface mount components in which a package IC such as a tline package), a resistor, and a capacitor are formed into a chip, the assembly of a printed circuit board is partially automated. By the way, many existing components with leads are used as resistors, capacitors and ICs, and these components are assembled by hand insertion together with other irregularly shaped components. For this reason, there is a demand for efficiently assembling a printed circuit board by such manual work. In view of this, the present inventors have proposed an assembling method capable of efficiently performing each process of work organization, component serving, and component insertion in the manual assembling process of a printed board (see Japanese Patent Application Laid-Open No. 6-45798). . According to this assembling method, automatic knitting for each worker (knitting in consideration of line personnel and tact balance) is performed in cooperation with CAD data, and each insertion work is performed based on knitting data created by the automatic knitting. Instructs the component placement (creation table creation) and parts insertion position using the screen (simple work drawings) to the operator, eliminating the need to manually create work drawings for each worker, and enabling efficient part insertion work Like that.

FIG. 21 shows the proposed assembling method.
FIG. 22 is a block diagram of the actualized printed circuit board assembly system.
Illustration of component mounting data, FIG. 23 shows creation of simple work organization table
It is a process explanatory view. In FIG. 21, reference numeral 1 denotes a CPU or a memo.
Computer with built-in memory
Data input device with a board
Data output devices 4a and 4b are CAD and CAM files.
Disk device with 5
Table with conveyor 5a to move ₁~ 6n
Indicate the component insertion position configured by the display device
Component insertion position indicating device, 7₁7n is printed circuit board, 8₁
To 8n are switches for inputting the end of component insertion, 9₁~ 9n
Barcode reader, 10₁10 to 10n are parts boxes (tray),
a₁To an are workers.

A PC of a printed circuit board is input from the data input device 2.
When the B figure number is input, the computer 1 enters the CAD / CAM
The files 4a and 4b are accessed to read out the component mounting data (FIG. 22) including the component list by drawing number, mounting position by component, component shape data, and the like. FIG. 22 shows the component mounting data.
As shown in (1), the attributes (component model, product name, mounting position, etc.) of all components required for one PCB drawing number (one printed circuit board) are covered by component symbols. Next, the computer 1 extracts the data of the automatically inserted parts, the retrofitted parts, and the missing parts of the CAM file 4b from the part mounting data to extract the manually inserted part data as shown in FIG. The manually inserted component data includes the type of component to be manually inserted, the height, and the total number of components for each type of component. Next, the computer 1 obtains the total number of hand-inserted parts from the extracted hand-inserted part data. Preferably, the extracted hand-inserted part data is classified into a plurality of types of heights according to the part shape data (height), and the total number of hand-inserted parts is determined for each height. FIG. 23 (b) is an example of an intermediate file showing the total number of hand-inserted parts by height. The total number of parts having a height of 1 (low) such as the resistor R and the integrated circuit IC is 142, and the switch SW , The total number of components having a height of 2 (high) such as the coil L is six.

Then, when the number of work organization members (for example, 4) is input from the data input device 2, the computer 1 allocates the number of hand-inserted parts to each worker by leveling the number of parts by part model. Therefore, all parts having the same model and different part symbols are allotted to one worker. Preferably, the number of hand-inserted parts by height is leveled to each worker of the input work organization number (four) in units of part model, and allocated so that lower parts are inserted earlier. . Then
The computer 1 creates a simple simplified work organization table including the types and numbers of hand-inserted parts allocated to each worker (process), and outputs it from the printer 3. FIG. 23 (c) is an example of a simplified work scheduling table. Here, the worker a ₁ (=
In step 1), 35 ICs and one switch SW are allocated, and to the worker a ₂ (= step 2), 35 resistors R and one switch SW are allocated, and similarly, other operations are performed. Parts of heights 1 and 2 are also allocated to the workers, so that the total value of the parts allocated to each worker is substantially equal. ... Simplified work knitting process

When the creation of the simplified work scheduling table is completed, the computer 1 extracts the component type data and the number of the corresponding component from the component mounting data of FIG. 22 based on the allocation of the scheduling table. A parts distribution table in which these are classified for each worker is output. It is desirable that the order in which the components are arranged for each worker is based on the insertion order of the component mounting data shown in FIG. Each part is prepared for the number of lots, a bar code ticket in which part type data is recorded is given for each type, and the parts are placed in the parts boxes 10 ₁ to 10 n and arranged for each worker. ... or, component insertion position indicator device 6 ₁ ~6n constituted by parts serving process display apparatus displays a component mounting drawings and the like of the printed circuit board on its screen, the component insertion position in a specific color, In addition to displaying the mark or blinking, the part where the component has been inserted and the part where the component has not been inserted are manually displayed in different colors.

When the PCB figure data of the printed circuit board is inputted from the keyboard 2, the computer 1 starts to operate the respective workers a ₁
.. An (manual insertion parts, post-installation parts, and missing parts parts are removed from the part mounting data of FIG. 22A). Then, the computer 1 displays the effect of component insertion position indication device 6 ₁ ～6N the mounting screen and component insertion start of the printed circuit board, waits for input of the model number data by the barcode reader 9 ₁ ～9N of each worker . Each worker a ₁ .about.An selects parts in each parts by part units from each component box 10 ₁ to 10n, by scanning a bar code tickets subjected to each part by the bar code reader 9 ₁ ~9n, the component Is input to the computer 1. Thus, the computer 1 instructs each worker component insertion position indication device 6 ₁ ～6N controlled to be the type rating to be inserted one position the components of the input from the operator (insertion position), insertion Wait for the end input.

[0008] Each operator a ₁ .about.An, together denoted a unique mark M ₁ to Mn in the first printed circuit board, inserting the components in the indicated inserted position by the component insertion position indication device 6 ₁ ~6n. Thereafter, until the detected visually unique mark M ₁ to Mn, inserting the parts of the same type rated at the same position of the printed circuit board coming one after another. And, its own mark M ₁ ~Mn
When the printed circuit board marked with come to return, remove the mark M ₁ to Mn, it presses the switch 8 ₁ ～8N, notifies the component insertion completion to the computer 1. In response to the part insertion completion notification, the computer 1 displays “inserted” at the position where the part has been inserted, and checks whether the insertion position of the part having the same model remains. Displays the insertion position. Thus, each worker repeats the above-described component insertion operation. If the insertion position of the component having the same model no longer remains, the computer 1 checks whether a component having another model remains without being inserted, and if it remains, the bar code reader 9 of each worker. ₁
Wait for the input of the pattern data by .about.9n, and after the input, repeat the above processing. ... Part insertion process

In the above-mentioned proposed assembling method, the operator inputs a part model to the computer 1 every time a part to be inserted is changed in the part inserting step. However, in such a method, if it takes time to input the part type, the operation of inserting the part cannot keep up with the speed of the conveyor 5a on the table 5, which hinders the insertion operation such as insertion omission. Therefore, there has been proposed a component insertion method in which it is not necessary to input the component model to the computer 1 every time the component model is changed (Japanese Patent Laid-Open No. 7-235799). Figure 24 is an explanatory view of a component insertion method, ₆₁ parts insertion position indication device constituted by a display device, 10 ₁₁ 10 ₁₃
Work by component box of a given operator a _1, 11 ₁ are parts task orchestration table of the worker a _1, which is ordered inserted.

Computer (Computer 1 in FIG. 22)
, Instead of the simple task orchestration table of FIG. 23 (c) in the knitting process, to create a component knitting table 11 ₁ marked with insertion order for each worker (step) and the work. That is, the computer 1 divides the inserted part into each operation (operation 1 to operation 3),
To create a component knitting Table 11 ₁ by determining the component insertion order according to a predetermined rule in each work. The insertion order shall be that the same model part is inserted continuously, and the parts shall be inserted in order from the lowest part height. If the parts height is the same, the parts shall be inserted in the order of small X coordinate value, and the X coordinate value shall be the same In the case of, insertion is performed in descending order of the Y coordinate value.

[0011] In serving process, providing a parts box 10 ₁₁ 10 ₁₃ for each task 1 Task 3, the parts box ₁₀₁₁
The parts in work 1 to work 3 corresponding to ₁₃ are stored and served to the worker. In the insertion step, the computer at the same time the display of the entire mounting diagram with reference to parts knitting Table 11 ₁ to the component insertion position indication device ₆₁ is inserted instruction from the insertion order young parts in the appropriate work order. That is, the computer displays an overall view of the printed circuit board to the component insertion position indication device ₆₁ on the display screen, to display all components to be inserted by the operator into the insertion position on the printed board,
In addition, the next component to be inserted is displayed so as to be distinguishable from other components. Thus, the operator takes out the designated parts from parts box 10 ₁₁ 10 ₁₃ which is serving by the work, inserting the said part to the position designated by the component insertion position indication device _61. FIG. 24 shows a case where the first part (part symbol D1) of operation 2 is identified and displayed as the next part to be inserted. After the insertion, if a switch (switch 8 _{1 in} FIG. 21) is pressed to notify the computer of the completion of the insertion, the computer displays the next component to be inserted so as to be distinguished from the others. Thereafter, the same operation is repeated, and the above operation is repeated until all the arranged component boxes are empty, thereby completing the component insertion operation.

Incidentally, the manual assembling process of the printed circuit board includes a component processing process, a masking process, a correcting process, and a finishing process, in addition to the above-described work organization, component serving, and component inserting processes. (1) In the part processing process, every time a new part is generated, a part standard processing drawing and a special processing drawing are created and registered in the work instruction book. Based on this work instruction book, lead bending, tube coating on the lead, etc. Of parts processing. (2) In the masking process, after the components are manually inserted into the printed circuit board, when passing through the solder dip layer, a masking work drawing (masking the stuck holes etc. An instruction) is created by painting the position of the tape to be colored, and a masking operation is performed based on this drawing. (3) In the correction process, a work drawing is created that specifies the work range for each worker based on the CAD drawing, and soldering of the manually inserted parts and correction of the lead cut exceeding the standard value are performed based on this work drawing. Do the work. (4) In the finishing process, mainly mechanical parts are assembled.
First, a mechanical drawing specified by the CAD mounting drawing is collected, and then a knitting table and a working drawing for each worker are created from the collected mechanical drawing, parts list, and mounting drawing, and assembling work is performed based on these drawings. Do.

[0013]

Conventionally, in these component processing, masking, correcting, and finishing processes, a work drawing is created based on a CAD drawing, and work is performed using the working drawing or the CAD drawing. Was to do. Therefore, there are the following problems. (1) Problems in the component processing process In component processing, it is necessary to judge standard processing or special processing depending on the conditions of the printed circuit board (whether or not there is a pattern under the inserted component). For this reason, an operation occurs in which the worker searches for a working drawing (standard working drawing or special working drawing) by referring to the work instruction book based on the part drawing number of each printed circuit board and the board conditions. For this reason, the work becomes complicated, and the decision of selecting a processing drawing is left to each worker, which causes a work error in parts processing. In addition, the complicated work as described above causes a hindrance to the realization of in-line processing (processing a part taken from a tray on an insertion line and inserting it as it is).

(2) Problems in the masking process and the correction process Since work drawings are disposable (management of each work drawing is too large to manage), the same PCB drawing number and version number are used. Even so, it is necessary to create work drawings (masking work drawings and correction work drawings) for each lot. For this reason, a lot of man-hours are required to create a work drawing, and a mistake in creating a work drawing occurs, which causes a decrease in work quality. (3) Problems in the finishing process A lot of man-hours are required to collect the mechanical drawings and create the organization chart and work drawings for each worker. Further, since work drawings (finish work drawings) are disposable, it is necessary to create work drawings for each lot even if the PCB numbers and plate numbers are the same. For this reason, an erroneous creation of a work drawing occurs, which causes a reduction in work quality.

(4) Problems in the component insertion process In the component insertion process, components are inserted according to the insertion order automatically determined by the computer. However, at this time, from which tray the parts in the insertion order specified on the screen should be taken out is determined by the composition table for each worker, which describes the correspondence between the insertion order and the part drawing number, and the picking attached to the tray They are found based on tickets (hereinafter referred to as part tickets). As described above, during the operation of inserting parts, the act of looking at the knitting table output for each worker and searching for the tray containing the ticket of the part drawing number corresponding to the insertion order occurs,
This is a factor that reduces the efficiency of insertion work. From the above, an object of the present invention is to provide a component insertion process, a component processing process, a masking process, a correction process,
In the manual work process such as the finishing process, there is no need to refer to paper drawings (realization of drawing-less work), and the manual work can be performed easily without mistakes, and the manual work can be efficiently performed. It is to provide.

The serving process DBP is a process in which all manual insertion components and mechanical components required for assembling the printed circuit board are stored in trays for each worker according to the knitting file and served. The component processing process PMP is a process of performing component processing work (pre-processing) such as lead bending and tube coating on leads.
The masking process is a process of attaching a masking tape to a printed circuit board to prevent solder from rising to the component mounting surface, the component insertion process is a process of inserting lead components etc. into the printed circuit board, and the repair process is a process of manually inserting components. The process of performing the soldering and the work of correcting the lead cut exceeding the standard value, and the finishing process FSP are the final processes of assembling the mechanical parts. In the parts processing process (pre-processing, in-line processing), the parts processing drawings are converted into images and the parts processing drawings are converted into drawing codes corresponding to the one-to-one correspondence.
By linking with the drawing code automatically or manually added to the knitting data, it is possible to display the image of the part processing drawing of the part to be pre-processed or in-line processed, and to improve the efficiency of pre-processing and in-line processing of parts I'm trying.
