A circuit board splitting jig and method of use thereof

Abstract

The invention discloses a board split jig of a circuit board. The board split jig comprises a cover board and a base board, the bottom is covered with the cover board, one side of the cover board is connected with the base board in a rotatable mode through more than two hinges, the base board is fixed on a board cutting machine, a through hole corresponding to a board cutting route of the circuit board is formed in the cover board, and grooves corresponding to protruding electronic elements on the surface of the circuit board are further formed in the cover board. A plurality of parting strips are arranged on the base board relative to the hollow edge of the circuit board, a location pin is arranged on the base board relative to a location hole in the circuit board, and a through hole is formed in the base board relative to the board cutting route of the circuit board. According to the board split jig of the circuit board, the step that an operator uses a supporting column to fix the circuit board is omitted, the labor strength is greatly reduced, and the cutting efficiency is improved. Meanwhile, as the turnover type cover board and protruding lugs are designed, small cut circuit board bodies and the board edges can be conveniently and rapidly taken, and the cutting efficiency is further improved.

Description

technical field [0001] The invention relates to a board cutting jig for circuit boards, in particular to a board splitting jig for circuit boards and a use method thereof. Background technique [0002] Printed circuit board PCB (Printed circuit board), also known as printed circuit board, printed circuit board, referred to as printed board, is based on an insulating board, cut to a certain size, with at least one conductive pattern attached to it, and holes ( Such as component holes, fastening holes, metallized holes, etc.), used to replace the chassis of electronic components installed in the past, and to realize the interconnection between electronic components. [0003] At present, printed circuit boards are widely used in electronic equipment, ranging from small electronic watches and calculators to large computers, monitors, and so on. At present, in the assembly of printed circuit boards in displays, in order to have high production efficiency, firstly, the printed ci...

Problems solved by technology

This traditional process has the following disadvantages: 1. It takes a long time to install and adjust the support column. After cutting each circuit board, it needs to be disassembled, and then install the next uncut large circuit board. It takes a lot of time to install and disassemble. The circuit board greatly affects the cutting efficiency; 2. The circuit board is supported by the support column. Since the circuit board is thin and long, the middle of the circuit board will be concave during cutting, causing the circuit board to be scrapped; 3. The circuit board is being divided. It is easy to be picked up by the dust collector above the cutting machine, causing the circuit board to be scrapped

[0007] 2. In this patent, the circuit board is fixed through the cooperation of the groove on the backing plate and the cover plate. In the actual application process, in order to facilitate the insertion of the circuit board into the groove, the electronic components will not be damaged due to extrusion. The size of the circuit board is usually slightly larger than the size of the electronic components on the circuit board. In this way, there is a certain movable space for the circuit board in the groove, and it is still easy to move the circuit board during the cutting process, resulting in failure to complete the cutting. Or the cutting is not accurate, and the circuit board is scrapped

It is also possible that the circuit board is not completely snapped into the groove, causing the electronic components to be squeezed and damaged

[0008] 3. The cover plate is fixed to the bottom plate by pins. Every time a cutting is completed, the pins and the cover plate need to be disassembled, which wastes a lot of working time and leads to low cutting efficiency.
