[0025] Reference Figure 1-4 This utility model discloses a wet cleaning device for semiconductor manufacturing, comprising: a workbench 1, a tank 2 at the upper end of the workbench 1, mounting brackets 3 fixedly connected to the upper end of the workbench 1 and on both sides of the tank 2, a guide groove 4 on one side of the mounting brackets 3, lifting seats 5 and 6 fixedly connected above the mounting brackets 3 respectively, lifting shafts 7 and 8 rotatably mounted inside the lifting seats 5 and 6 respectively, a pulley 9 fixedly connected to the outer wall of the lifting shaft 7, a winding wheel 10 fixedly connected to the outer wall of the lifting shaft 8, a lifting rope 11 wound around the outer wall of the winding wheel 10, a motor 12 fixedly connected to the upper end of the mounting brackets 3, the output end of the motor 12 connected to the lifting shaft 8, a receiving rail 13 above the tank 2, and a filter assembly 14 at the lower end of the workbench 1.
[0026] The filter assembly 14 is fixedly connected to the filter box 141 at the bottom of the workbench 1. Filter plates 142 and activated carbon plates 143 are fixedly connected to the inner walls of the filter box 141. A pump body 144 is fixedly connected to one side of the filter box 141, and a return pipe 145 is fixedly connected to the output end of the pump body 144. The filter assembly 14 can filter the cleaning solution containing impurities in the tank 2.
[0027] The end of the return pipe 145 away from the pump body 144 is located on the upper side of the tank 2. The return pipe 145 facilitates the delivery of the cleaning solution filtered in the filter box 141 to the tank 2 for secondary use.
[0028] A drain pipe 201 is provided at the bottom of the tank 2, and a drain valve 202 is provided on one side of the drain pipe 201. The end of the drain pipe 201 away from the tank 2 is connected to the filter box 141. The drain valve 202 and the drain pipe 201 facilitate the discharge of the cleaning liquid in the tank 2 into the filter box 141.
[0029] A guide rod 401 is slidably connected to the inner wall of the guide groove 4. One end of the lifting rope 11 passes through the pulley 9 and is connected to the top of the guide rod 401, and one end of the guide rod 401 is fixedly connected to the receiving rail 13. The guide groove 4 improves the stability of the guide rod 401 during lifting, thereby keeping the receiving rail 13 stable during lifting.
[0030] Multiple ultrasonic generators 203 are installed at the bottom of the tank 2, and the multiple ultrasonic generators 203 are arranged symmetrically. The ultrasonic generators 203 further enhance the cleaning effect of the semiconductor.

[0033] Working principle: During use, the semiconductor to be cleaned is placed in the receiving compartment 13, and the motor 12 is started to output the lifting shaft 8 to drive the winding wheel 10 to rotate. The rotation of the winding wheel 10 causes the lifting rope 11 to pull the guide rod 401 to move up and down in conjunction with the pulley 9. The guide rod 401 moves up and down, causing the receiving compartment 13 to enter into the tank 2 or rise from the tank 2, thereby completing the placement and retrieval of the semiconductor. When the semiconductor is placed in the tank 2, the ultrasonic generator 203 can be started to enhance the cleaning effect. After each semiconductor is cleaned, the drain valve 202 can be opened to discharge the cleaning liquid in the tank 2 into the filter box 141 through the drain pipe 201. The filter plate 142 and activated carbon plate 143 in the filter box 141 filter the cleaning liquid to ensure the purity of the cleaning liquid. After filtration, the cleaning liquid can be sent back to the tank 2 through the return pipe 145 by the pump body 144 to achieve recycling.
