Multi-splicing PCB (printed circuit board) patch clamp and production process thereof

Abstract

The invention provides a multi-splicing PCB (printed circuit board) patch clamp, which is used for combining a plurality of PCBs onto one clamp for patch production. The clamp comprises a universal support plate and a base, wherein the shapes and the dimensions of the universal support plate are matched with those of the base, the universal support plate is arranged on the base, the front and back sides of the universal support plate are respectively provided with at least one front side position avoiding region and at least one reverse side position avoiding region with different sizes, a plurality of support plate positioning posts and a plurality of groups of PCB positioning posts corresponding to the plurality of PCBs are fixedly arranged on the base, a plurality of support plate positioning holes matched with the support plate positioning posts are formed in the universal support plate, the plurality of groups of PCB positioning posts respectively correspond to the PCB positioning holes formed in the plurality of PCBs, and the plurality of groups of PCB positioning posts pass through the universal support plate to be matched with the corresponding PCB positioning holes. According to a production process, the clamp is introduced for production. The multi-splicing PCB patch clamp and the production process of the multi-splicing PCB patch clamp provided by the invention have the advantages that the production cost can be reduced, and the precision can be improved.

Description

technical field [0001] The invention relates to a PCB (Printed Circuit Board, printed circuit board) patch fixture and its production process, in particular to a multi-piece PCB patch fixture suitable for a small number of PCB components and its production process. Background technique [0002] The actual production capacity of SMT (Surface Mount Technology, surface mount technology) ultra-high-speed patch line is at least 100,000 components / hour, and the number of components in some PCBs is very small, such as a PCB with only 300 components , The placement machine only needs 10 seconds to complete, and the printing and other process steps will become the bottleneck restricting the production speed. The speed advantage of the placement machine will not be able to play, and it is far from meeting the production capacity of the placement machine. The multi-collage fixture of the prior art requires a set of dedicated pallets for each model. If the production is stopped or the d...

[0002] The actual production capacity of SMT (Surface Mount Technology, surface mount technology) ultra-high-speed patch line is at least 100,000 components / hour, and the number of components in some PCBs is very small, such as a PCB with only 300 components , the placement machine only needs 10 seconds to complete, and the printing and other process steps will become the bottleneck restricting the production speed, and the speed advantage of the placement machine will not be able to play, which is far from meeting the production capacity

The multi-collage fixture of the prior art requires a set of dedicated pallets for each model. If the production is stopped or the design is changed, the entire set of fixtures will be scrapped, resulting in cost waste, and the pallets of the prior art The positioning column is generally installed manually, and the positioning accuracy cannot be guaranteed
