A device and method for pcb board mounting and positioning

Abstract

The invention provides a PCB plate mount-connect positioning device and method; the device comprises two leading screw mechanisms, wherein the first set refers to a transmission mechanism using a horizontal leading screw shaft as the main body, and the second set refers to two transmission mechanisms using a vertical leading screw shaft as the main body; the PCB plate mount-connect positioning device can horizontally and vertically fix a PCB plate, thus satisfying product laminate high consistency and reliable welding technical requests, and solving the problems that a conventional machine fitting is various in product types, thus causing large clamp tool processing load; aiming at a dual-layer PCB plate product of different sizes, only one machine fitting set is needed and developed; the device and method has no limits on product pin structures, are strong in versatility, convenient in adjustment, thus greatly saving clamp tool developing and making costs.

Description

technical field [0001] The invention belongs to electronic products, and relates to a PCB board welding and assembling process, in particular to a device and method for mounting and positioning a PCB board. Background technique [0002] With the continuous development of the electronics industry, there are more and more requirements and types of electronic products, and the process is becoming more and more complex. Double-layer or even multi-layer PCB board products are emerging; the assembly process requirements for PCB board products are also increasing in production. High, double-layer PCB board products often need to connect the upper and lower panels. In order to meet the welding process requirements of the upper and lower boards, each PCB board product needs a plywood fixture to ensure the height and reliability of the product assembly. PCB board assembly includes mold positioning and welding. Positioning link: According to the size and height of the product, a speci...

AI Technical Summary

Problems solved by technology

Due to the variety of electronic products, various sizes and pin structures, it is required to design different fixtures for different products, which is cumbersome to develop. Each fixture can only be connected to one PCB board product, resource sharing cannot be realized, and the production cost is very high.

As far as the method of mounting and connecting the PCB board and board of electronic products is concerned, the main disadvantages of the existing assembly process are: 1. Each fixture can only install and connect one electronic product, fixture resources cannot be shared, the investment cost is too large, and the production fixture cycle is long , There are many types, the production cost is very high, and a variety of fixtures need to be managed and maintained, which consumes manpower and material resources

2. The existing plywood fixture cannot be adjusted. If the product structure size changes, the plywood fixture needs to be remade
