Anti-stacking device for circuit board substrate

Abstract

A circuit board substrate anti-stacking device includes a frame side plate correspondingly arranged on the left and right, a material plate arranged between the frame side plates, and a vacuum suction cup arranged above the middle of the material plate. A movable plate is also symmetrically arranged on the left and right above the material plate. An anti-skid strip is vertically installed on the opposite side of the movable plate, and the other side of the movable plate is connected to the frame side plate through a first cylinder. A first limiting rod and a second limiting rod are arranged on the material plate to enclose a space for accommodating the circuit board substrate. The vacuum suction cup is installed at the bottom of the lifting plate. The device mainly uses a vacuum suction cup to absorb the circuit board substrate for positioning. At the same time, movable plates with anti-skid strips are arranged on both sides to make the anti-skid strips contact with both sides of the circuit board substrate respectively. The vacuum suction cup drives the circuit board substrate to move up and down reciprocatingly, and the friction between the anti-skid strip and the circuit board substrate is used to remove the excess circuit board substrate, ensuring that the vacuum suction cup only takes away one circuit board substrate for processing at a time. The structure is simple and the damage to the circuit board substrate is small.

Description

Technical Field

[0001] The utility model relates to an anti-stacking device for a circuit board substrate. Background Art

[0002] The processing of circuit boards requires board loading, degreasing, water washing twice, micro-etching, water washing twice, pickling, copper plating, water washing, nickel plating, water washing and gold plating. The copper plating, gold plating or micro-etching in the circuit board processing procedures are all handled by automated assembly lines, and the assembly lines generally use automated loading, which mainly uses suction cups to adsorb the circuit boards so that the circuit boards can be loaded in single pieces. However, when loading a single piece, adsorption is prone to occur, causing two or even more pieces to be adsorbed together. Generally, continuous knocking and vibration are used to separate the adsorbed circuit boards. If the knocking force is too small, it is not easy to separate the circuit boards, and if the knocking force is too large, the circuit boards are easily damaged. Utility Model Content
