Description

Technical Field

[0001] The utility model relates to the technical field of switch shrapnel processing, in particular to a switch shrapnel feeding mechanism. Background Art

[0002] Metal shrapnel is mainly used in membrane switches, contact switches, PCB boards, FPC boards, medical devices and other products. Traditional assembly operations mostly rely on manual labor, which has technical problems such as low assembly efficiency and unstable assembly quality. A few companies use automated assembly equipment, which generally uses automated methods to effectively load and process switch shrapnel.

[0003] For example, the utility model with application number 202223316857.3 discloses a switch spring feeding mechanism, which mainly utilizes the adjustment of the positioning mechanism to allow the adsorption component to move to a position suitable for loading, and drives the carrying bar to adjust the angle by starting the electric shaft output power on the inner side of the partition block, so that the carrying bar cooperates with the electromagnetic suction cup to fit onto the switch spring, and the electromagnetic suction cup attracts the switch spring through the electromagnetic force of the adsorption component on the equipment. In this way, when the equipment is loading, since the whole process adopts the electromagnetic force grabbing method, the clamping contact effect is avoided, so that the structural damage caused by the switch spring during transportation can be prevented.

[0004] Similar to the above application, there are still some shortcomings:

[0005] The switch spring feeding mechanism uses electromagnetic force to attract the switch spring to avoid damage to the spring. Although it reduces the damage rate caused by clamping, the switch spring can only load part of the switch spring material at a time. The use of a screw rod to drive the electromagnetic suction cup to move back and forth results in a long interval between material collection and unloading, affecting the feeding efficiency.

[0006] Therefore, a switch spring feeding mechanism is designed to optimize the above-mentioned problem. Utility Model Content
