[0027] Embodiment 1: As shown in the accompanying drawings, an LCD terminal cleaning machine includes a base 1, fixing bolts 2, and a receiving frame 3. The fixing bolts 2 are threadedly installed on the base 1, and the receiving frame 3 is fixedly connected to the top of the base 1. It further includes a cleaning assembly for cleaning the surface of the glass substrate.

[0028] In this embodiment, specifically, the cleaning assembly includes a first non-woven pad 4, a second non-woven pad 5, a wiping plate 6, an electric push rod 7, a material pushing plate 8, a pushing rod 9, and a replenishing assembly. The first non-woven pad 4 is installed in the material receiving frame 3. When the glass substrate is unloaded into the material receiving frame 3, the first non-woven pad 4 can clean the bottom of the glass substrate. The second non-woven pad 5 is installed on the base 1. The wiping plate 6 is rotatably installed on the base 1 and is located above the second non-woven pad 5. As the glass substrate moves, the wiping plate 6 and the second non-woven pad 5 cooperate to clean the upper and lower surfaces of the glass substrate. In this way, impurities on the surface of the glass substrate can be avoided, which may affect the subsequent production quality. The electric push rod 7 is fixedly connected to the inside of the base. The material pushing plate 8 is slidably connected to the material receiving frame 3. The pushing rod 9 is fixedly connected between the telescopic end of the material pushing plate 8 and the electric push rod 7. The replenishing assembly is used to replenish alcohol for cleaning the wiping plate 6. Among them, the replenishing assembly includes a support frame 10, a material box 11, a pressing plate 12, a material blocking block 13, a first spring 14, and a clamping assembly. The support frame 10 is fixedly connected to the top of the base 1. The upper part of the support frame 10 is inclined. The material box 11 is fixedly connected to the top of the wiping plate 6 and is communicated with the wiping plate 6. The pressing plate 12 is slidably connected to the inside of the material box 11. The material blocking block 13 is slidably connected to the communication part between the material box 11 and the wiping plate 6. The first spring 14 is connected between the material blocking block 13 and the wiping plate 6. The clamping assembly is used to clamp the replaced non-woven fabric. When cleaning alcohol is put into the material box 11, during the downward sliding of the glass substrate, the glass substrate will push the wiping plate 6, causing the lower part of the wiping plate 6 to rotate upward and tilt, thereby driving the material box 11 and the pressing plate 12 to move upward. Under the limiting action of the support frame 10, the pressing plate 12 will have a downward force, thereby squeezing the alcohol in the material box 11 into the wiping plate 6. During this period, the material blocking block 13 will be pushed to move downward, and the first spring 14 will undergo adaptive deformation. In this way, automatic feeding of the non-woven fabric can be achieved, and there is no need to manually replenish the cleaning alcohol. Secondly, the clamping assembly includes a fixed rod 15, a U-shaped sliding rod 16, a pressing block 17, a second spring 171, and a pressing groove 18. The fixed rod 15 is fixedly connected to the top of the wiping plate 6. The U-shaped sliding rod 16 is slidably connected to the fixed rod 15. The pressing block 17 is fixedly connected to the end of the U-shaped sliding rod 16. The second spring is connected between the U-shaped sliding rod 16 and the fixed rod 15. The pressing groove 18 is opened on the top of the wiping plate 6. The pressing block 17 and the pressing groove 18 are used in cooperation. The non-woven fabric is sleeved on the bottom of the wiping plate 6. Under the action of the second spring 171 and through the cooperation of the pressing block 17 and the pressing groove 18, the pressing block 17 can press and limit the non-woven fabric.

[0029] Further, it further includes a loading component for transporting the glass substrate.

[0030] The loading component includes a fixed seat 19, a rotating seat 20, a rodless cylinder 21, a connecting rod 22, a motor 23, a large gear 24, a small gear 25, and a material suction component. The fixed seat 19 is fixedly connected to the base 1. The rotating seat 20 is rotatably connected within the fixed seat 19. The rodless cylinder 21 is fixedly connected to the top of the rotating seat 20. The connecting rod 22 is fixedly connected to the side wall of the slider of the rodless cylinder 21. The rodless cylinder 21 controls the up-and-down movement of the connecting rod 22 through the slider. The motor 23 is installed on the side wall of the fixed seat 19. The large gear 24 is key-connected to the rotating seat 20. The small gear 25 is key-connected to the output shaft of the motor 23. The large gear 24 and the small gear 25 are meshed. The rotation of the small gear 25 drives the rotation of the large gear 24, thereby enabling the rotation and displacement of the rodless cylinder 21, facilitating the loading of the glass substrate. The material suction component is used to adsorb the glass substrate for transporting the glass substrate. Among them, the material suction component includes a fixed block 26, a suction plate 27, a suction cup 28, a plug plate 29, a return spring 291, and a material receiving component. The fixed block 26 is fixedly connected to the end of the connecting rod 22. The suction plate 27 is fixedly connected to the end of the fixed block 26. The suction cup 28 is fixedly connected to the bottom of the suction plate 27. The suction cup 28 is communicated with the suction plate 27. The plug plate 29 is slidably connected to the suction plate 27. The plug plate 29 blocks the suction cup 28. The return spring 291 is connected between the plug plate 29 and the fixed block 26. The material receiving component is used to make the suction cup 28 unload the glass substrate. During the up-and-down movement of the connecting rod 22, it drives the fixed block 26, the suction plate 27, the suction cup 28, and the plug plate 29 to move up and down, facilitating the adsorption of the glass substrate by the suction cup 28, and further facilitating the loading of the glass substrate. Secondly, the material receiving component includes a contact rod 30 and a contact plate 31. The receiving frame 3 is fixedly connected to the top of the base 1. The contact rod 30 is fixedly connected to the side wall of the plug plate 29. The contact plate 31 is fixedly connected to the top of the receiving frame 3. The movement of the contact rod 30 contacts the contact plate 31, driving the movement of the plug plate 29, enabling gas to enter the suction cup 28, and the suction cup 28 releases the glass substrate to achieve unloading. Driven by the up-and-down movement of the suction cup 28 and the plug plate 29, it further drives the movement of the contact rod 30 to contact the contact plate 31, thereby causing the plug plate 29 to move upward, and the return spring 291 undergoes adaptive deformation, thereby causing the suction cup 28 to release the glass substrate.

[0031] It should be noted that the inner wall of the receiving frame 3 is inclined to center the unloaded glass substrate. The inside of the wiping plate 6 is hollow to facilitate spraying alcohol for cleaning on the replaced non-woven fabric.

[0032] The above description is only for the best embodiment of the present invention, but it should not be construed as a limitation on the claims. The present invention is not limited to the above embodiments, and its specific structure allows for variations. All variations made within the scope of the protection of the independent claims of the present invention are within the scope of the present invention.
