[0022] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0023] like Figures 1 to 4 As shown, a wafer tray cleaning device is used to clean the upper surface of a wafer tray 30 transported by a wafer tray conveyor line 20, and includes a frame 1, a lifting plate 2, a wiping module 3, a lifting drive mechanism 4 and a horizontal drive mechanism 5.

[0024] Specifically, Figure 2 As shown, the wiping module 3 includes a mounting seat 31, a material unwinding reel 32 for placing the non-woven fabric roll 10, a material receiving reel 33, a rewinding drive assembly 34, a sponge roller 35 and an alcohol adding assembly 36. The mounting seat 31 is horizontally slidably connected to the lifting plate 2; the rewinding drive assembly 34 is used to drive the rewinding reel 33 to rotate to rewind the non-woven fabric; the sponge roller 35 is installed below the mounting seat 31 and contacts the non-woven fabric passing below the sponge roller 35; the adding end of the alcohol adding assembly 36 is arranged close to the sponge roller 35, and is used to add alcohol to the non-woven fabric.

[0025] In this embodiment, the winding drive assembly 34 includes a driving wheel, a driven wheel, a second belt and a second motor. The driving wheel is rotatably arranged on the mounting seat 31 and connected to the output end of the second motor. The driven wheel is coaxially connected to one end of the winding reel 33 and is connected to the driving wheel through the second belt.

[0026] In this embodiment, the lower end of the mounting seat 31 is connected to a bearing seat 311, and both ends of the roller shaft 351 of the sponge roller 35 are connected to the bearing seat 311 through elastic connection components. Figure 4 Further, the elastic connection assembly includes a guide pin and a spring 312, the end of the roller shaft 351 of the sponge roller 35 can be slidably arranged in the slide groove opened by the bearing seat 311 through the guide pin, and the spring 312 is located between the top surface of the slide groove and the end of the roller shaft 351, and is sleeved on the guide pin.

[0027] During the process of wiping the wafer tray 30 , due to the elastic force of the spring 312 , the sponge roller 35 is urged to press the non-woven fabric located below tightly against the wafer tray 30 , so as to achieve a better wiping effect.

[0028] In this embodiment, the alcohol adding component 36 includes an alcohol tube 361 and a dripping head 362 or a nozzle connected to the lower end of the alcohol tube 361. When in use, alcohol can be added to the non-woven fabric by dripping alcohol or spraying alcohol.

[0029] In this embodiment, two guide rollers 37 are arranged between the unwinding reel 32 and the sponge roller 35; a detection sensor 38 for detecting the non-woven fabric is arranged between the two guide rollers 37. The detection sensor 38 is preferably an infrared sensor.

[0030] In the wafer tray cleaning device, a barrel 6 for placing a spare non-woven fabric roll 10 is provided on one side of the frame 1. When the detection sensor 38 does not detect the non-woven fabric, it means that the non-woven fabric roll 10 has been used up and the spare non-woven fabric roll 10 needs to be placed on the unwinding reel 32.

[0031] like Figure 1 As shown, in the wafer support cleaning device, the lifting drive mechanism 4 is used to drive the lifting plate 2 to move up and down relative to the frame 1, and includes two lifting cylinders 41. Among them, guide rods 42 are arranged on both sides of the lifting cylinder 41, and the guide rods 42 are slidably matched with the guide sleeves 43 installed on the frame 1, and the lower ends of the guide rods 42 are connected to the lifting plate 2.

[0032] like Figure 2 and 3 As shown, the horizontal driving mechanism 5 is used to drive the wiping module 3 to move horizontally relative to the lifting plate 2, and includes a pulley 51, two guide wheels 52, a first belt 53 and a first motor 54. The pulley 51 is rotatably arranged on the mounting seat 31, and the two guide wheels 52 are rotatably arranged on both sides above the pulley 51; the first belt 53 passes from below the pulley 51 and above the two guide wheels 52, and both ends of the first belt 53 are connected to the lifting plate 2 through a fixing assembly 55; the first motor 54 drives the pulley 51 to rotate relative to the mounting seat 31.

[0033] When in use, under the drive of the first motor 54 and the transmission action of the pulley 51 and the first belt 53, the mounting seat 31 slides relative to the lifting plate 2, driving the sponge roller 35 and the non-woven fabric pressed on the upper surface of the crystal tray by the sponge roller 35 to move horizontally to perform a wiping action.

[0034] The fixing assembly 55 includes an upper fixing block 551 and a lower fixing block 552, which are arranged one above the other. The upper fixing block 551 and the lower fixing block 552 are locked and connected by a set of screws. A plurality of racks are arranged on the bottom surface of the upper fixing block 551 to increase the friction force on the belt 53 and ensure that the belt 53 is firmly fixed.

[0035] In this embodiment, two fixing components 55 are installed on the top surface of the lifting plate 2 ; and an avoidance groove 21 for avoiding the two guide wheels 52 is opened on the lifting plate 2 .

[0036] Furthermore, the installation position of at least one of the two fixing components 55 on the lifting plate 2 is adjustable along the sliding direction of the mounting seat 31. The lifting plate 2 is provided with a long strip-shaped adjustment hole, and a locking screw is provided in the adjustment hole for fixing the lower fixing block 552 to the lifting plate 2.

[0037] In this embodiment, two photoelectric switches are installed on the lifting plate 2, and a light shielding plate 7 for triggering the two photoelectric switches is connected to the mounting seat 31.

[0038] The utility model is a crystal tray cleaning device. When in use, under the drive of the lifting drive mechanism 4, the lifting plate 2 moves downward, driving the wiping module 3 to move downward, so that the sponge roller 35 presses the non-woven fabric on the upper surface of the crystal tray 30; under the drive of the horizontal drive mechanism 5, the wiping module 3 moves horizontally relative to the lifting plate 2, and wipes the upper surface of the crystal tray 30 through the sponge roller 35 and the non-woven fabric; before and during wiping, alcohol can be added to the wiping position of the non-woven fabric through the alcohol adding component 36. Through multiple reciprocating movements of the wiping module 3, the upper surface of the crystal tray 30 can be wiped back and forth multiple times; after wiping, under the drive of the horizontal drive mechanism 5 and the lifting drive mechanism 4, the wiping module 3 is reset. Under the drive of the winding drive component 34, the material receiving reel 33 rotates to wind up the non-woven fabric, prompting the non-woven fabric below the sponge roller 35 to be updated, so as to facilitate the next round of wiping operations.

[0039] Compared with the prior art, the crystal tray cleaning device of the utility model can effectively avoid secondary pollution because the non-woven fabric is rolled up and updated after wiping; and there is no need to set up drying equipment, the structure is compact, and the space occupied is small.
