The top of the fixing plate 15 is connected with a water tank 14 by bolt connection, and the bottom middle of the water tank 14 is connected with a water pump 17 by bolt connection. A hose 18 is connected to the 17 through a flange connection. A cleaning frame 19 is placed on the top right side of the bottom plate 20. The water outlet of the hose 18 is located above the cleaning frame 19. The lower right wall of the cleaning frame 19 is welded with a water outlet pipe 21. The water pipe 21 is provided with a valve 22, the top right end of the bottom plate 20 is welded with a right frame 23, the left frame 16 and the right frame 23 are welded with a top plate 10, and the bottom of the top plate 10 is welded with a second guide sleeve 9, a frame 12 and The first guide sleeve 6 and the second guide sleeve 9 are slidably provided with a second guide rod 8, and the first guide sleeve 6 is provided with a first guide rod 5 in a sliding manner. The second guide rod 8 and the first guide rod 5 There is a movable frame 11 welded between, and the bottom end of the bracket 12 is fixedly connected with a motor 7 by means of bolts. The output shaft of the motor 7 is welded with rotating rods 13 evenly spaced. The rotating rods 13 are matched with the movable frame 11, and the bottom of the movable frame 11 A cylinder 4 is connected in the middle by bolt connection, the bottom end of the cylinder 4 is connected with a hollow cleaning box 1 by a bolt connection, the top of the right wall of the hollow cleaning box 1 is connected with a hinge 2 by a screw connection, and the hinge 2 passes through The box cover 3 is connected by screw connection, and the hollow cleaning box 1 is located directly above the cleaning frame 19.

[0029] A filter screen 24 is also included, and the other end of the hose 18 is connected with a filter screen 24.

[0030] It also includes a reinforcing rib 25, the upper right part of the left frame 16 is welded with a reinforcing rib 25, and the right end of the reinforcing rib 25 is welded to the left side of the bottom of the top plate 10.

[0031] The material of the bottom plate 20 is stainless steel.

[0032] The material of the cleaning frame 19 is Q235 steel.

[0033] The material of the hose 18 is PVC.

[0034] Working principle: When using this equipment, the worker first opens the lid 3, pours a certain amount of silicon wafers to be cleaned into the hollow cleaning box 1, and then closes the lid 3. Then the water pump 17 is controlled to work. At this time, the water in the water tank 14 enters the cleaning frame 19 through the hose 18. After an appropriate amount of clean water is installed in the cleaning frame 19, the water pump 17 is controlled to stop working. Then control the cylinder 4 to extend, and then drive the hollow cleaning box 1 to move downwards. When the hollow cleaning box 1 is located in a suitable position in the cleaning frame 19, the cylinder 4 is controlled to stop working. Then control the motor 7 to rotate clockwise, the motor 7 drives the rotating rod 13 to rotate clockwise, and then the rotating rod 13 drives the moving frame 11 to move left and right through the second guide rod 8 and the first guide rod 5, so that the moving frame 11 drives the cylinder 4 and The upper device moves left and right. Repeatedly, the hollow cleaning box 1 continuously swings left and right, so that the silicon wafers in the hollow cleaning box 1 are fully in contact with the clean water in the cleaning frame 19, and the silicon wafers are cleaned more thoroughly. When the silicon wafers in the hollow cleaning box 1 are completely cleaned and the hollow cleaning box 1 moves to the original position, the motor 7 is controlled to stop working, and then the cylinder 4 is controlled to contract, thereby driving the hollow cleaning box 1 to move upward, and the hollow cleaning box 1 After resetting, the control cylinder 4 stops working, and then the worker opens the valve 22. At this time, the water after cleaning the silicon wafer in the cleaning frame 19 flows out through the outlet pipe 21. When the water after cleaning the silicon wafer in the cleaning frame 19 flows out, the worker The valve 22 is closed, and then the box cover 3 is opened, the silicon wafers after the cleaning in the hollow cleaning box 1 are taken out, and the box cover 3 is closed.

[0035] Because the filter net 24 is also included, the other end of the hose 18 is connected with the filter net 24 to prevent impurities in the water from entering the water pump 17 through the hose 18 to avoid damage to the water pump 17.

[0036] Because it also includes a reinforcing rib 25, the upper right side of the left frame 16 is welded with a reinforcing rib 25, and the right end of the reinforcing rib 25 is welded to the bottom and the left side of the top plate 10, adding a joint surface between the upper right side of the left frame 16 and the bottom left side of the top plate 10 The strength of this equipment makes the service life of this equipment longer.

[0037] Because the bottom plate 20 is made of stainless steel, which has strong corrosion resistance and acid resistance, the service life of the equipment is longer.

[0038] Because the material of the cleaning frame 19 is Q235 steel, Q235 steel has high hardness and is not easy to deform, so that the service life of the equipment is longer.

[0039] Because the hose 18 is made of PVC material, it has high mechanical strength, high elongation, soft products, and good corrosion resistance and electrical insulation.
