The LCD screen glass is placed on the conveyor belt for transportation, and the conveyor belt is continuously rotating. The rotation of the conveyor belt drives the reciprocating assembly to move back and forth along the lower end surface of the plastic whiteboard. At this time, the plastic whiteboard generates static electricity. When the LCD screen glass is transported to the cleaning shell and the lower end of the plastic whiteboard via the conveyor belt, the static electricity on the plastic whiteboard absorbs the dust on the LCD screen glass. The utility model relates to the technical field of LCD screen glass detection. The device has the effect of timely cleaning dust adhered to the surface of the LCD screen glass, ensuring that it will not affect the detection of the LCD screen glass, thereby improving the detection efficiency.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1 - Figure 7 , the utility model provides a technical solution: Example 1:

[0029] A device for detecting LCD screen glass includes a conveyor 1, a horizontal plate 2 fixedly connected to the top of the conveyor 1, a support block 3 fixedly connected to one side of the horizontal plate 2, a camera 4 fixedly mounted on the bottom of the support block 3, a controller 5 fixedly mounted on one side of the conveyor 1, a compression box 6 provided on one side of the horizontal plate 2, a plurality of air injection pipes 7 fixedly connected to the bottom of the compression box 6 via a one-way pressure valve, a nozzle 8 fixedly connected to one end of the air injection pipe 7, a T-shaped block 9 fixedly connected to one side of the compression box 6, a T-shaped chute 10 for use with the T-shaped block 9 provided on one side of the horizontal plate 2, an air collecting mechanism provided on the top of the horizontal plate 2, and an adjustment mechanism provided on one side of the compression box 6;

[0030] The air collecting mechanism includes an air collecting box 11 fixedly connected to the top of the horizontal plate 2. The top of the air collecting box 11 is fixedly connected to the air intake pipe 12 through a first one-way valve. One side of the air collecting box 11 is fixedly connected to a transmission pipe 13. One end of the transmission pipe 13 is fixedly connected to the top of the compression box 6 through a second one-way valve. A motor 14 is fixedly installed on the top of the horizontal plate 2. The output end of the motor 14 is fixedly connected to a screw rod 15. The surface of the screw rod 15 is transmission-connected to a transmission block 16. One side of the transmission block 16 is fixedly connected to a push rod 17. One end of the push rod 17 passes through the interior of the air collecting box 11 and is fixedly connected to a push block 18.

[0031] In this embodiment, it is taken into consideration that dust may adhere to the surface of the LCD screen glass during the inspection and transportation process, and the dust on the glass may affect the inspection. Therefore, an air collecting mechanism is provided, so that while the LCD screen glass is being transported on the conveyor, the screw rod 15 is driven to rotate by the starting motor 14. When the screw rod 15 rotates, the transmission block 16 is driven to move back and forth along the track of the sliding block 26 and the sliding groove 27. When the transmission block 16 drives the push rod 17 and the push block 18 to move to the right, the push block 18 drives the piston 28 to move to the right, thereby compressing the air in the air collecting box 11. The gas enters the compression box 6 through the transmission pipe 13. When the transmission block 16 moves to the left, it drives the push rod 17, the push block 18 and the piston 28 to move to the left. At this time, the air collecting box 11 is under negative pressure, and the gas enters the air collecting box 11 through the air inlet pipe 12. The gas circulates in sequence and intermittently compresses the gas into the compression box 6. When the air pressure in the compression box 6 is higher than the limit of the one-way pressure valve, the gas is ejected from the nozzle 8 through the jet pipe 7. The gas from the compression box 6 is ejected onto the surface of the LCD screen glass, which can effectively remove dust. When the LCD screen glass passes through the bottom of the camera 4 for inspection, it will not be affected by dust, thereby improving the accuracy of the inspection.

[0032] Solved the problem that during the inspection and transportation process of LCD screen glass, dust may adhere to the surface of the glass, which may affect the inspection;

[0033] It should be noted that the first one-way valve is a valve that can only allow air to enter the air collecting box 11 , and the second one-way valve is a valve that can only allow air to enter the compression box 6 .

[0034] A sliding block 26 is fixedly connected to the bottom of the transmission block 16 , and a sliding groove 27 for use with the sliding block 26 is formed on the top of the cross plate 2 .

[0035] In this embodiment, by providing the sliding block 26 and the sliding groove 27, when the screw rod 15 rotates to transmit the transmission block 16 and other structures, the transmission block 16 and other structures can only move along the trajectory of the sliding block 26 and the sliding groove 27, and at the same time make the movement process more stable.

[0036] A piston 28 is fixedly connected to one side of the push block 18 , and the piston 28 is made of rubber.

[0037] In this embodiment, by providing the piston 28 , the sealing performance of the push block 18 can be improved, so that the gas in the gas collecting box 11 can be compressed during the movement of the push block 18 .

[0038] The transmission pipe 13 is a rubber hose, and the air injection pipe 7 is a universal bamboo tube.

[0039] In this embodiment, a transmission tube 13 and an air jet tube 7 are provided. The transmission tube 13 is a rubber hose to avoid damage to the compression box 6 when the position is adjusted. At the same time, the air jet tube 7 is a universal bamboo tube to adjust the air jet angle, thereby improving the dust cleaning effect. Example 2:

[0040] On the basis of Example 1, the gas collecting mechanism in this embodiment compresses the gas and then sprays it onto the LCD screen glass to remove dust. However, considering the different thicknesses of the LCD screen glass, if the jet height is not suitable, it will also affect the cleaning effect. The adjustment mechanism in this application includes a positioning frame 19 fixedly connected to one side of the compression box 6, one side of the positioning frame 19 is fixedly connected to a traction block 20, one side of the traction block 20 is fixedly connected to a traction rod 21, one end of the traction rod 21 passes through the interior of the positioning frame 19, and is fixedly connected to an extrusion block 22, one side of the extrusion block 22 is fixedly connected to a positioning rod 23, and one side of the cross plate 2 is provided with a positioning hole 24 for use with the positioning rod 23.

[0041] In this embodiment, taking into account the different thicknesses of LCD screen glasses, if the jet height is not suitable, the cleaning effect will be affected. Therefore, an adjustment mechanism is provided, which can drive the traction block 20 to move the traction rod 21, the extrusion block 22 and the positioning rod 23, so that the positioning rod 23 leaves the interior of the positioning hole 24, thereby releasing the restriction on the compression box 6. After that, the height of the compression box 6 can be adjusted along the trajectory of the T-shaped block 9 and the T-shaped slide 10. After reaching the appropriate position, the traction block 20 is released, and the elastic force generated by the spring 25 pushes the extrusion block 22 and the positioning rod 23 to reset, so that the positioning rod 23 enters the corresponding positioning hole 24, completing the adjustment of the position of the compression box 6, thereby achieving the adjustment of the jet height and improving the dust cleaning effect.

[0042] Solve the problem that the cleaning effect will be affected if the jet height is not suitable due to the different thickness of LCD screen glass.

[0043] A spring 25 is sleeved on the surface of the traction rod 21 . One end of the spring 25 is fixedly connected to one side of the extrusion block 22 , and the other end of the spring 25 is fixedly connected to the inner wall of the positioning frame 19 .

[0044] In this embodiment, by providing the spring 25 , when the traction block 20 is released, the elastic force generated by the spring 25 pushes the extrusion block 22 and the positioning rod 23 to move, thereby achieving a reset effect.

[0045] There are a plurality of positioning holes 24 , which are evenly distributed on one side of the transverse plate 2 .

[0046] In this embodiment, by providing a plurality of positioning holes 24 , after the position of the compression box 6 is adjusted, the positioning rods 23 can enter the corresponding positioning holes 24 , thereby achieving a quick positioning of the compression box 6 .

[0047] Working principle: When the LCD screen glass is transported on the conveyor, the screw rod 15 is driven to rotate by starting the motor 14. When the screw rod 15 rotates, it will drive the transmission block 16, so that the transmission block 16 moves back and forth along the track of the sliding block 26 and the sliding groove 27. Figure 7 As shown, when the transmission block 16 drives the push rod 17 and the push block 18 to move to the right, the push block 18 will drive the piston 28 to move to the right, compressing the air in the air collecting box 11, so that the gas enters the compression box 6 through the transmission pipe 13. When the transmission block 16 moves to the left, it will drive the push rod 17, the push block 18 and the piston 28 to move to the left. At this time, the air collecting box 11 is under negative pressure, and the gas will enter the air collecting box 11 through the air inlet pipe 12, and circulate in sequence, intermittently compressing the gas into the compression box 6. When the air pressure in the compression box 6 is higher than the limit of the one-way pressure valve, the gas will be ejected from the nozzle 8 through the injection pipe 7. The gas in the compression box 6 will be ejected on the surface of the LCD screen glass, which can effectively remove dust. When the LCD screen glass passes through the bottom of the camera 4 for subsequent inspection, it will not be affected by dust, thereby improving the accuracy of the inspection.

[0048] At the same time, according to the thickness of the LCD screen glass, the traction block 20 can be pulled to drive the traction rod 21, the extrusion block 22 and the positioning rod 23 to move, so that the positioning rod 23 leaves the inside of the positioning hole 24, and the restriction on the compression box 6 is released. After that, the height of the compression box 6 can be adjusted along the trajectory of the T-shaped block 9 and the T-shaped slide 10. After reaching the appropriate position, the traction block 20 is released, and the elastic force generated by the spring 25 will push the extrusion block 22 and the positioning rod 23 to reset, so that the positioning rod 23 enters the corresponding positioning hole 24, completing the adjustment of the position of the compression box 6, and then achieving the adjustment of the jet height, thereby improving the dust cleaning effect.
