Abstract
Description
Technical Field
[0001] This utility model relates to the field of wafer handling equipment technology, and in particular to a wafer handling drive device and system. Background Technology
[0002] A wafer handling robot is an automated device used in the semiconductor manufacturing process to handle and process fragile and critical wafers. Wafers are the fundamental material for semiconductor chip manufacturing and need to be handled and processed in various manufacturing steps. Therefore, specially designed and precisely operated robots are required to accomplish these tasks. Currently, the robot's mounting end is usually connected to a drive unit, which drives the robot to lift, rotate, and move, thereby meeting the robot's handling needs at different heights and angles.
[0003] Because the drive unit lacks a waterproof design, moisture or condensation can seep into the mechanical interfaces of the drive unit, such as the motor shaft, gearbox, and cable inlet, in humid environments. This leads to a shortened material fatigue life, such as reduced elasticity of the sealing ring and oxidation of the PCB copper foil. Frequent disassembly, cleaning, or replacement of rusted parts is required, reducing equipment utilization. Utility Model Content

[0011] The locking member presses against the first elastic part and locks the protective cover and the baffle plate. The first elastic part seals the connection between the baffle plate and the gasket to prevent water from seeping into the transport frame.
[0012] The washer has a second elastic part on the other side, and the second elastic part has a second mounting hole that communicates with the washer. The locking member passes through the second mounting hole.
