Whole panel cutting device and cutting method for jigsaw of printed circuit board

Abstract

The invention relates to a cutting printed wiring board panel, specifically a panel cutting device and a cutting method of printed wiring board panel. According to the design proposal provided by the invention, a long knife is arranged and fixed on a lateral side of a forward and backward movable platform. A circular knife is arranged above the long knife, with a knife edge paralleled and jointedwith the knife edge of the long knife. And the circular knife can rotate on a central shaft. The invention has the advantages of simple cutting control, few biased cutting, least shearing stress generated, no damage on the printed wire plate or precision components thereon, great cutting speed improvement, production cost saving and production efficiency improvement.

Description

Whole board cutting device and cutting method for printed circuit board assembly technical field The invention relates to cutting printed circuit board panels, in particular to a complete board cutting device and cutting method for printed circuit board panels. Background technique As electronic products are getting smaller and smaller, the size of printed circuit boards is also required to be smaller and smaller. Therefore, in the production process of printed circuit boards, in order to save costs, small-sized printed circuit boards are assembled on a large-sized printed circuit board, so that it can be manufactured according to the large-sized printed circuit board process, but this also gives Dao's processing manufacturers bring the process of cutting and separating small-sized printed circuit board products from the entire board. Although this process is simple, the wiring on the small-sized printed circuit board is dense, and the components on it are also relatively...

AI Technical Summary

Problems solved by technology

The defects of the prior art are: 1. The stress generated by breaking directly by hand is the largest, which can cause the edge of the printed circuit board to break or break, and is not easy to control, directly affecting the product function and appearance performance, resulting in a substantial decline in product yield, resulting in A lot of cost wasted

2. Although the use of tools can reduce the stress, it is relatively easy to control, but the stress generated by shearing will be transmitted through the printed circuit board. If there are some precision components on the board, they are very sensitive to stress and easy to damage, which will lead to the failure of the final product. damage
