The utility model discloses a height adjusting device for automobile detection platform relates to automobile detection platform technical field. The height adjusting device for automobile detection platform includes the mount, the upper portion of mount is provided with adjusting mechanism: drive assembly, including fixed mounting on the upper portion of mount and is increased height frame, the upper portion fixed mounting of height frame has the shell, the upper end fixed mounting of shell has the top, the upper portion fixed mounting of top has drive motor, rotates through drive motor and drives gear, and two groups of planetary gears are under the double restraint of the tooth profile structure of shell inner wall and drive gear, transmission frame bottom gear -like convex, revolve around drive gear, and also carry out autogyration, realize deceleration and increase the moment, and the tooth profile convex of transmission frame bottom and the planetary gear of output frame upper portion secondary reduce output speed and improve output torque, so that drive motor can select low output torque's model, thereby reduce the volume of drive motor, avoid the device volume too big.

The utility model provides a wafer lifting, clamping and rotating cleaning device, and relates to the technical field of wafer cleaning, the wafer lifting, clamping and rotating cleaning device comprises a cleaning tank and a pre-cleaning mechanism, one side of the inner wall of the cleaning tank is provided with a transmission track, one side of the outer wall of the cleaning tank is provided with a feeding port, one side of the inner wall of the cleaning tank is provided with a megasonic cleaning machine, and the other side of the inner wall of the cleaning tank is provided with a feeding port. The pre-washing mechanism comprises a fixed aluminum plate and two servo motors, and speed reducers are arranged on the tops of the two servo motors. In the utility model, under the action of the two lifting cylinders and the four vertical guide rails, the two lifting cylinders and the four vertical guide rails drive the two fixed plates, the two movable plates, the four driving rotating shafts and the four rotating shaft sleeves to move upwards, so that the rotating shaft clamping sleeves are ensured to be on a track transmission plane and then extend out through the two clamping centering cylinders; the wafer is driven to rotate to drive the rotating shaft and the related components to move inwards together and stop after extending to the limiting positions of the first limiting screw and the second limiting screw, the air cylinder is magnetically opened and fed back in place, and at the moment, wafer clamping is completed.
