Description

TECHNICAL FIELD

[0001] The present application relates to the field of electronic components paint stripping, in particular to an electronic component automatic paint stripping equipment. BACKGROUND

[0002] In the batch production of electronic components, small and micro components often use the process of painting first and then stripping to make product electrodes.

[0003] In the prior art, there is a paint stripping equipment that uses a vibrating disc and a straight vibration guide rail to feed. The vibrating disc and the straight vibration guide rail have very limited requirements for product size and cannot be used for all products. If different models of products need to be produced, it takes a long time to switch and the production speed is slow. In addition, the vibrating disc and the straight vibration guide rail are expensive, increasing the investment cost of the production line.

[0004] The existing paint stripping equipment also includes an automatic winding and stripping device for an integrally formed inductor, disclosed in Chinese Patent No. CN209328713U, which includes a workbench and a chain conveying mechanism fixed on the workbench through support feet. An inductor coil automatic winding mechanism and an inductor coil automatic stripping mechanism are arranged along the conveying direction of the chain conveying mechanism. The inductor coil automatic winding mechanism is a four-axis winding mechanism. The inductor coil automatic stripping mechanism includes a laser paint stripping machine and a limiting support with a limiting opening located directly below the laser paint stripping machine. The limiting support is fixed on the workbench, and the chain conveying mechanism passes through the inside of the limiting support. A jacking mechanism is arranged inside the limiting support below the limiting opening. The device also includes a driving mechanism that drives the vertical movement of the jacking mechanism.

[0005] The paint stripping device provided by the above patent can only strip the inductor coil from one direction. The inductor coil needs to be manually flipped before it can be stripped again, which causes a great waste of labor.

[0006] For example, a top and bottom laser paint stripping machine is disclosed in Chinese Patent No. CN102856776A, which includes a rack. A straight linear slide rail is fixed on the rack. A sliding table that can move horizontally along the linear slide rail is installed on the linear slide rail. A workpiece positioning table for placing workpieces to be stripped is installed on the sliding table and can move vertically. An upper laser emission gun and a lower laser emission gun are installed on the rack above and below the workpiece positioning table, respectively.

[0007] Although the device provided by the above patent can achieve double-sided paint stripping of electronic components, the feeding process is complex and it is difficult to achieve fully automated paint stripping. SUMMARY
