A configuration is provided in which the product insertion position is shown, and the display is used to know the component mounting position on the printed wiring board and perform component mounting.

[Industrial applications]

The present invention relates to a component insertion work instruction device for assembling a printed wiring board.

The assembling work of a printed wiring board, so-called _Pt board, is roughly classified into automatic assembling by an automatic inserting machine and manual assembling by manual insertion, and the present invention relates to the latter.

[Conventional technology]

Manual assembly is typically bill-mounting Figure collected to one Kesho the P _t plate and components for assembling, and conduct while find search collation and the insertion position of the parts and time consuming.

An automatic assembling support system has been developed to rationalize this manual assembling work, and the present inventor has also developed and applied for an automatic assembling assisting system for designating a part insertion position with a light spot. In the method of mounting an electronic component on a printed wiring board according to this patent application, parts list data and insertion position data of components to be inserted into the printed wiring board are stored in a computer in advance, and if a drawing number of the printed wiring board is input, the relevant A component type table of various components mounted on the printed board, a component list for each component type, and the like are displayed on a display. Then, set the printed wiring board on which the components are to be mounted on the set part of the workbench, place the parts box containing the various parts on the workbench, enter the _Pt board drawing number etc. and enter the component type of the mounted parts on the display Display the table. Next, the worker randomly picks up the parts from the parts box, and if it is a resistance, selects "resistance" from the parts type table, displays a parts list for the resistance, and displays the parts of the resistance taken out of the parts box. Those that match the drawing numbers are indicated in the parts list. In response to this, the computer obtains the insertion position of the component from the storage device, and moves the optical indicator to illuminate the insertion position of the component. The operator inserts the removed component into the light irradiation position. Hereinafter, this is repeated to mount all components.

[Problems to be solved by the invention]

In the previously proposed system, so that the optical indication device can be irradiated accurately light a component insertion position, positioned on a workbench on a predetermined position P _t plate, there is a constraint that must be light irradiated in that state.

However, in correction operation of retrofit operation or already fitting parts to P _t plate has manually P _t plate, it is necessary to proceed with or inside out, on a workbench to a predetermined position, and the table in front It is difficult to position correctly.

An object of the present invention is to improve such a point, and an object of the present invention is to provide a component insertion work instruction apparatus suitable for adding and correcting parts of a _Pt plate that has been automatically assembled.

[Means for solving the problem]

As shown in FIG. 1, in the present invention, the printed wiring board P _t
And data relating to component mounting on the _Pt board are stored in a computer. This data, drawing number of the P _t plate and outer (size, etc.), all components of the component type to be mounted to said P _t plate, drawing number of each component, include part code and the component insertion position data.

Also, various components to be mounted on the _Pt board are prepared for each component drawing number. For this purpose, for example, a component box and a bag may be used, and various components may be put in the bag for each drawing number, and the bag may be put in the component box.

Here, the component type is a resistor, a capacitor, an IC, and the like, and the component number is an ID code for identifying the resistor, the capacitor, the IC, and the like from each other, and is assigned by each manufacturer. The part code, but attaching a plurality of, for example, a resistor in P _t plate is generally, but representing the respective R1, R2, ......, or the like. The P _t plate drawing number is the P _t plate ID code. ID
As the code, a unit number, a production number (production number), or the like can be used.

In mounting the parts, the operator inputs working conditions such as the _Pt board drawing number to the computer. In response to this, the computer searches the data file and displays a list of component types of components to be mounted on the corresponding _Pt board on the display.

The operator arbitrarily takes out the parts bag from the parts box, and inputs the type of the parts in the parts group contained in the bag by using the above display (points the corresponding field on the display surface with a cursor). Upon receipt of this, the computer accesses the data file and displays a list of parts drawing numbers of the parts of the kind (resistance, capacitor, etc.) on the display.

The operator inputs the figure number of the part in the bag using the display. Computer To that accesses the data file, displays the P _t board mounting position of the component of the parts number in the display.

The operator sees this display, knows the position on the _Pt plate,
Attach the parts at that position.

Forth, it performed per all components to be inserted to such an operation, complete the component mounting operation of the P _t plate.

[Action]

In this method, P _t plate diagram number input, the component type and a parts number entered in the computer can display P _t plate upper part insertion position, the component insertion position as the corresponding position on the P _t plate to see this Know and install the parts. P _t plate is not necessary to position the worktable on a predetermined position, since only take action display and P _t plate on the display visually, may have a hand P _t plate, the mounting operation It's easy to do.

If the mounting parts of the P _t plate there is a very large number it is, is only the position display on the display, but it is not easy work to go attach the parts to know the appropriate position on the P _t plate, retrofit and already with parts Since the number of parts to be attached is small in the correction, only the position display on the display is sufficient.

〔Example〕

2 to 5 show an embodiment of the present invention. FIG. 2A is an external view and 10 is a work table. Multiple sheets on a workbench 10, in this example placed the four P _t plates 11 to 14, also a keyboard 15, mouse 16, CRT display 17, component box 18 is placed, also disk 19, the microcomputer (processor) 20 etc. can be attached.

The parts box 18 as shown in FIG. (B), the various parts to be attached to P _t plate 11 to 14, resistors, capacitors, IC, ......
In addition, even the same capacitor can be put into various types of containers such as ceramic capacitors, tantalum capacitors, etc., and in this example, put in a bag. The bag also contains a ticket, and the part drawing number of the corresponding part and the number of parts contained in the bag are marked on the ticket.

P _t plate 11 to 14, most of the components mounted in an automated assembly, which has been soldered through the soldering device,
Only a few dozen retrofitted parts have not been installed.
To P _t plate as shown in FIG. 5 (c), such as parts of the symbol to be attached are printed in serigraph.

The processor 20, the display 17, and the like are connected as shown in FIG. 3, that is, similarly to a known microcomputer system. Reference numeral 21 denotes a communication interface with the host computer, and reference numeral 19 denotes a hard disk in this example. Next, the component mounting area will be described with reference to FIG.

The operator places a required number of _Pt plates on which the parts are to be mounted (however, up to four in this example) in predetermined positions on the work table 10. This P _t
The position where the plate is placed may be shifted from the predetermined position, and positioning accuracy is not required.

Next, the operator operates the keyboard 15 to display an input message on the display, and inputs work conditions such as the figure number of the _Pt plate placed on the work table. The work conditions include a unit drawing number, a manufacturing number ( _Pt plate drawing number), a production quantity (4 in this example), and also includes “end” at the end of the work.

When working conditions, such as P _t plate drawing number is input processor Toyo the relevant data from the database DB of the host, thereby reading the data file DF disk 19 searches the component type list, to the P _t plate A list of component types of components to be attached is displayed on the display 17. This display state is shown in FIG. The As illustrated display, component type i.e. resistance component to be attached to the P _t plate, ceramic capacitors (ceramic capacitor), an integrated circuit (I
C), hybrid integrated circuit (HIC), tantalum capacitor, ...
(Part type list) is displayed.

The operator arbitrarily (randomly) takes out a bag (bag such as vinyl) containing the parts from the parts box, and inputs the type of parts contained in the taken-out bag. This is a mouse
Perform 16 by operating. That is, since the cursor on the display surface of the display for operating the mouse moves, when the cursor moves to the corresponding part type, the switch attached to the mouse is pressed, and the extracted part is, for example, a resistor. When this part type is input (part type selection),
The display surface changes to FIG. 4 (b). That because there is the P _t resistance also various to be attached to plate, it retrieves the various (parts number list), and displays. The removed bag contains a ticket in addition to the part, and the ticket number of the part is written on the ticket. The operator reads it and operates the mouse to input a part drawing number on FIG. 4 (b).
This input area is the same as in the case of component type selection.

When this part drawing number is selected, the processor searches the data file DF for the coordinate data of the insertion position of the part drawing number, performs a screen output data calculation process, and displays the part insertion position display as shown in FIG. Do. In this display, as shown, P _t plate drawing number H16B- ○○○○ - ×××× and, together with the drawing number H40L-3301-0002 # 1EQ insertion part, are displayed the component insertion position. This a frame F indicating the contour of P _t plate, insertion position within that frame (indicated by the small rectangle), a part code (in this example
R1 to R4). Various components are attached to the _Pt plate, but there is no indication of various components in this component insertion position display, and a frame F, a small rectangle indicating the insertion position, and a component are displayed with the dark color of the display surface of the display as a background color. Only the symbols R1 to R2 are displayed with high brightness. The operator watching this display, to know the relevant sections of P _t plate on the work table, read the part code that is printed there, and it and to correspond on the display, the components contained in the extracted bag The insertion position can be easily known.

The operator inserts the parts to the component insertion position in his hand a P _t plate, turned over P _t plate, carry out the soldering of the inserted parts. The same process is performed for a plurality of component insertion positions and a plurality of _Pt plates, and the insertion of the component of the corresponding component drawing number is completed. This is input by a mouse, and in response to this, the processor deletes the data of the part drawing number. Insertion work completion input data includes (1) one part drawing number insertion completion (NEXT),
(2) One-part drawing number insertion completed (to the part type selection screen),
(3) There is insertion work completion (to the input message display screen).

In this example, the operator inputs (2) as input data if there are still parts to be attached. Thus, the process jumps to the step after the determination step, and the display of FIG. 4A is made. The operator arbitrarily reads out the bag from the parts box, and selects a part type by looking at the parts contained in the bag. This causes the display of FIG. 4 (b) to be performed, and the part drawing number is selected by looking at the ticket in the bag, and FIG. 4 (c).
Is displayed. Interpolation included the parts in the bag worker that fetched while viewing the display to the corresponding position of the P _t plate, soldered. The same applies hereinafter.

When the insertion work is completed, the part drawing number may be moved to “with / without remaining” without inputting data. Parts drawing number remaining /
If there is any remaining, the processor determines that there is nothing, so if there is any remaining, the display of FIG. 4 (b) is performed, and if there is no remaining, the display of FIG. 4 (a) is performed. In the former case, the operator takes out a bag of the same kind as the one previously taken from the parts box, in this example, containing the resistor, and selects a part drawing number.
In the latter case, the operator takes out an arbitrary bag from the parts box and selects a part type.

Worker when performing all the parts mounting to P _t plate inputs the input data "3" at step 17 to return to the first step. In this state, the next group of printed boards is placed on the workbench, and the operation for mounting the components is started. When no longer be P _t to be mounted, to enter the "Exit" in step. When this is recognized in the step, the system stops.

Display of the display data can be obtained from the CAD data of the P _t plate. The small rectangular frame in FIG. 3 (c) indicating the insertion position can be calculated as a stripe of a predetermined width covering the left end X, Y coordinate and the right end X, Y coordinate indicating the terminal position. Is displayed in a blinking manner. For a wide object such as an IC, a rectangular area that covers the upper left and lower X and Y coordinates and the lower right and X and Y coordinates is calculated, and the mounting position is displayed by blinking the rectangular area. If the round parts are also square in the mounting position display, and three-terminal parts such as transistors are approximated by two terminals, the display can be simplified.

The part mounting position display shows the mounting positions of all the mounting parts (at most 20 to 30 pieces because they are retrofitted), and it is possible to blink the mounting position of the input part drawing number, change the color, etc. Good.

Also, as shown in FIG. 4 (c), only the mounting position of the input part drawing number may be displayed, one of them may be blinked in the mounting order, and the mounting position display may be deleted when the mounting is completed. Details can be modified as appropriate.

〔The invention's effect〕

As described above, according to the present invention, compared with a mere manual assembly, it is not possible to efficiently check the part drawing number to be attached and the part symbol with the mounting drawing, confirm the insertion position of the part, and reduce the manufacturing cost. Product quality can be improved.
