Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production method and apparatus used for automatic assembly of printed circuit boards used in electric equipment.

[0002]

2. Description of the Related Art In the conventional production method, after a sales order report for a device (product), a part is ordered through multiple departments such as design, technology, construction and materials based on design information.

Therefore, when the delivery date of the parts is not in time, the ordering action is carried out after discussion among the multiple departments.

When an alternative product is ordered, delivered, and then delivered to the assembly process due to the delivery time of the product, the product name of the parts list (a list of parts used for assembly) remains unchanged.

[0005]

However, in the above-mentioned conventional method for producing a printed circuit board, there is a problem that the process up to ordering the parts is spread over many departments, so that the action up to the ordering is delayed.

Further, when the delivery time of the arranged parts is not in time, there is a delay in the work in each department and a further delay in ordering the parts until a conclusion is reached such as a meeting of the products to which the parts are allocated and a request for changing the parts to the design department. There was a problem that it occurred.

Further, since the name of the component at the time of design is registered in the mounting data, when the substitute product is delivered, an inquiry is made to the design department, construction work, and materials due to the difference in the component name. However, there was a problem that production was delayed.

Furthermore, there is a case where the inquiry is neglected and different parts are mounted, resulting in a defect. In order to solve the above problems, the present invention eliminates consensus, automatically places an order according to a component arrangement (ordering) priority in consideration of alternative products at the time of designing, and performs production after generating mounting data with the ordered component product name. Accordingly, it is an object of the present invention to provide a method and an apparatus for producing a printed circuit board, which shortens the lead time from the production order to delivery and reduces defects during production.

[0009]

In order to achieve the above object, the method for producing a printed circuit board according to the present invention uses a database of product order information (product name, order quantity, etc.) input from a terminal of each sales office. (Hereinafter, referred to as “DB”), the order information is transmitted to the design information management unit at the same time.

Next, the parts list D. B. The parts information is searched according to the order of priority of parts registered in
Search the inventory of each parts manufacturer connected by modem and place an order automatically.

Further, the mounting data information management unit is configured to change the product name of the mounting data in accordance with the name of the part that has been reserved and ordered.

[0012]

With the above configuration, the lead time from order receipt to delivery can be shortened by automating the ordering of parts from the sales order information and the creation of the mounting data with the ordered part name. In addition, since it has a simple structure, mistakes and defects that occur during the process can be reduced.

0 is a flowchart of a processing program of the printed circuit board production system executed by the automatic mounting machine terminal 60.

In FIG. 2, the order information 12 from each of the sales offices 11 to 13 is the order information D. B. 1
3 to the modem. (Step S1) This order information 12 includes the customer name, device name, and
The number of sets, the delivery date, the product name that makes up the device, the model,
The order information D.
B. At the time of registration at 13, the numbers are automatically generated in the order of registration, and the serial number of the representative number and the item number which is the number for each product are set.

Next, the sales information management section 10 receives the order information 1
The product information 14 in which the product number and the like are added to 2 is transmitted to the design information management unit 20.

The design information management section 20 uses the "product name" of the received product information 14 as a key to input the parts list information D.
B. The corresponding parts list information 22 is selected from 21 (step S2) and transmitted to the parts information management unit 30. In the parts list information 22, the priority of parts arrangement, the names of parts, and the number of parts are registered.

The parts information management unit 30 includes the parts list 22 and the parts information D. B. Check 31 and select parts to arrange. (Step S3) At this time, since the standard part information 32 and the serial number part information 33 are registered for each part name, the standard part and the serial number part are automatically classified. (Step S3) Next, it is determined whether or not it is a standard part. (Step 5) In the case of a standard part, it is confirmed whether or not the status of the number of parts in stock is equal to or greater than the ordered number. Make a reservation to leave the warehouse. (Step S7) Purchase reservation list information 34 is created in the case where the preset minimum inventory quantity is 200 or less due to the delivery reservation, and in the case of serial number parts. (Step S8) Next, based on the purchased parts list information 34, the parts (stock) information of each parts manufacturer connected by the modem is searched. (Step S9) In this case, the parts manufacturer having the highest priority in the parts arrangement is searched first, and if the parts are in stock (step S10), the order is placed (purchase reservation). (Step S18) If there is no stock, the parts manufacturer having the second highest priority of arrangement is searched. (Step S12) Search all target parts manufacturers (Step S1)
1) After that, for parts that are not in stock, a delivery date inquiry list 35 is created for each parts manufacturer and sent by modem. (Step S13) At the same time, the part information D. B. Search for the corresponding parts that have been received, and sort in order from the latest production date. (Step S14) Next, if the number of parts to be stored is equal to or greater than the number of items to be ordered (the number of purchases) (step S15) and the delivery date of the device is later than the device (step S16), an allocated product is selected.

Then, when the delivery date of the reply from each component manufacturer is three days or more earlier than the delivery date of the allocated product, allocation is performed. (Step S17) If the delivery date of the part is later than the delivery date of the allocated product, or if there is no allocated product, the device name and the delivery date for which the delivery date needs to be changed are displayed on the screen of the workstation of the parts information management unit 30. The item name, delivery date, and manufacturer's name of the part whose delivery time is too late are displayed in the lower row.

This information is automatically transmitted to the sales office 11 in charge, and the system waits for input of the change delivery date of the device.

When the changed delivery date is input, the ordered parts list information 36 is created and sent to the mounting data information management section 40 after the order is placed with the parts manufacturer (step S17).

The mounting data information management unit 40 stores the mounting data D. B. The component data name of the mounting data 42 managed in 41 is changed to the component product name of the ordered component list information 36 (step S19), and the mounting data 42 'is transmitted to each terminal 61 to 65 for the automatic mounting machine. (Step S20)

[0035]

As is apparent from the above description, according to the present invention, parts ordering is automatically performed based on the sales order information.
Further, by automatically performing the generation of the mounting data based on the order information, it is possible to shorten the lead time from the order receiving to the delivery, and it is also possible to reduce defects during assembly.
