Description

TECHNICAL FIELD

The device addresses the problem of low efficiency in patching multiple circuit boards simultaneously, as the original patching device can only patch one circuit board at a time. The device fixes the circuit board in a long slot on the patching plate, starts the servo motor, and drives the transmission plate to move at a constant speed. When the transmission plate reaches a certain position, it pauses, and the electric telescopic rods start to move downward, along with the patching heads.

If these impurities are not completely removed, they can seriously affect the quality of the patching, leading to poor welding, short circuits, and other problems, thereby reducing the reliability and performance of electronic products. Simple wiping or blowing is not enough to effectively remove stubborn contaminants such as oil on the surface of the circuit board. After using some cleaning methods, there may be residues of cleaning agents, such as organic solvents, on the circuit board, which can cause subsequent problems such as corrosion, affecting the electrical performance and service life of the circuit board.
