Description

Technical Field

[0001] This utility model relates to the field of chip manufacturing protection technology, specifically an external protection device for the production of thyristor chips. Background Technology

[0002] With the rapid development of technology, silicon chips, as a core material in the electronics industry, require particularly high levels of safety, stability, and efficiency in their production process. Silicon chip production involves extreme conditions such as high temperatures and high pressures, and often generates harmful gases and microparticles, all of which threaten the production environment and the safety of operators. Therefore, providing effective external protection for the silicon chip production process to ensure its stability and the safety of operators has become an urgent problem to be solved.

[0003] The prior art discloses an external protective device for silicon chip production, with publication number CN210850869U. It includes a top plate, a fixed frame integrally formed on the bottom surface of the top plate, guide plates connected to both outer sides of the fixed frame, and guide holes penetrating the surface of the guide plates. A lifting frame is fitted onto the outer side of the fixed frame, and a bearing plate is connected to both outer sides of the lifting frame. A guide post is mounted on the upper surface of the bearing plate, and a compression spring is fitted onto the outer side of the guide post. The upper end of the guide post penetrates the guide hole and is connected to a connecting plate. A lifting post is connected to the bottom surface of the connecting plate, and the bottom end of the lifting post extends into the fixed frame and is connected to an elastic telescopic rod. A scraper is installed at the telescopic end of the elastic telescopic rod. The beneficial effect is that the compression spring presses the bearing plate, causing the bearing plate to drive the scraper downwards via the guide post, connecting plate, and lifting post. The scraper cleans the inner wall of the fixed frame, eliminating the need for manual cleaning and facilitating the recycling and reuse of mortar.

[0004] The aforementioned external protective device for chip production uses a compression spring to press the support plate, which in turn drives a scraper to descend via guide columns, connecting plates, and lifting columns. The scraper cleans the inner wall of the fixed frame, ensuring internal cleanliness. However, the device lacks a protective structure and has no protective buffer components on the outside of the housing, resulting in insufficient protection and poor performance during use. Improvements are needed. Utility Model Content
