[0018] 2. In the present invention, when the top block rises, the driving gear and the side rack mesh with each other and rotate, and the rotation of the driving gear drives the bidirectional screw to rotate. The bidirectional screw drives the pressure plates to approach each other to squeeze the auxiliary air bag body, and the gas in the auxiliary air bag body is blown out through the soft air pipe and the air groove, thereby pneumatically cleaning the small liquid crystal glass fragments remaining on the conveying roller, reducing the workload of subsequent staff.

[0019] 3. In the present invention, when opening the movable baffle, the staff can drive the winding wheel and the first bevel gear to rotate through the traction rope, and the first bevel gear drives the second bevel gear and the threaded rod to rotate synchronously. The rotation of the threaded rod body can drive the cleaning plate to move along the upper surface of the receiving slide, and the liquid crystal glass fragments on the receiving slide are pushed together to facilitate subsequent unified processing.

DETAILED DESCRIPTION

[0028] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0029] like Figure 1-6 As shown, a re-inspection and conveying mechanism for liquid crystal glass comprises a conveying seat 1, and a plurality of groups of conveying rollers 6 arranged at intervals on the inner walls of both sides of the conveying seat 1. A movable truss 31 is movably arranged on the table top of the conveying seat 1, and a movable seat 32 is movably arranged on the movable truss 31. A re-inspection module 33 for photographing the liquid crystal glass is arranged on the movable seat 32. A supporting base 34 is arranged at the bottom of the conveying seat 1. The conveying rollers 6 support both sides of the liquid crystal glass and transport it, and the liquid crystal glass is photographed and re-inspected by the erected re-inspection module 33.

[0030] It also includes a cleaning component arranged on the conveying seat 1; wherein the cleaning component includes a main airbag body 7 and a receiving slide plate 8 arranged inside the conveying seat 1, and the receiving slide plate 8 is slidably distributed above the main airbag body 7, and the inner walls on both sides of the conveying seat 1 are provided with sliding grooves for limiting the receiving slide plate 8, and the top end surface of the receiving slide plate 8 is recessed downward from both sides, and its cross section is V-shaped, and a plurality of groups of spaced support air pipes 9 are arranged on the inner walls on both sides of the conveying seat 1, and a storage sleeve 10 is arranged at one end of the support air pipe 9, a piston rod 11 is slidably arranged inside the storage sleeve 10, and a top block 12 is arranged at the top of the piston rod 11, and the top block 12 is in the shape of a right triangle and is inclined to the On the top, the top block 12 is located between the conveying rollers 6, and the connecting pipes 21 for connecting the main airbag body 7 and the supporting air pipe 9 are arranged on both sides of the conveying seat 1. The inner walls on both sides of the conveying seat 1 are provided with a plurality of groups of spaced side racks 13. The interior of the top block 12 is divided into an airbag cavity and an active cavity by a partition plate 14. The interior of the airbag cavity is provided with an auxiliary airbag body 15 and a pressure plate 16, and the pressure plate 16 is slidably distributed on both sides of the auxiliary airbag body 15. The two sides of the top block 12 are provided with air grooves 17 that communicate with the active cavity. The air grooves 17 are connected to the output end of the auxiliary airbag body 15 through a soft air pipe 18. The interior of the active cavity is provided with a bidirectional screw 19 that matches the pressure plate 16. The bidirectional screw 19 A driving gear 20 is arranged in the middle part. When the top block 12 is rising, the driving gear 20 and the side rack 13 mesh with each other and rotate. When the liquid crystal glass is broken during transportation, most of the liquid crystal glass fragments will fall onto the receiving slide 8. The end surface of the receiving slide 8 is concave downward from both sides, so that the liquid crystal glass fragments falling thereon slide downward under the action of their own gravity and accumulate in the central area of ​​the receiving slide 8, which is convenient for subsequent cleaning. At this time, the gravity on the receiving slide 8 becomes larger, and it begins to slide downward along the slide groove to squeeze the main airbag body 7. The main airbag body 7 is deformed and collapsed under the pressure. At this time, the gas in the main airbag body 7 is input into the storage through the connecting pipe 21. The piston rod 11 and the top block 12 are driven to move upward in the sleeve 10, and the liquid crystal glass fragments stuck between the conveying rollers 6 can be lifted up by the rise of the top block 12, thereby ensuring the normal rotation of the conveying rollers 6. When the top block 12 rises, the driving gear 20 and the side rack 13 mesh with each other and rotate, and the rotation of the driving gear 20 drives the bidirectional screw 19 to rotate. The bidirectional screw 19 drives the pressure plates 16 to move closer to each other to squeeze the auxiliary air bag 15. The gas in the auxiliary air bag 15 is blown out through the soft air pipe 18 and the air groove 17, thereby the fine liquid crystal glass fragments remaining on the conveying roller 6 can be pneumatically cleaned, reducing the workload of subsequent staff.

[0031] In this embodiment, specifically, longitudinal rod frames 3 are mounted at both ends of the conveying seat 1, and the longitudinal rod frames 3 are located above the receiving slide plate 8, and the top end faces thereof are convex upward from both sides, and the top end faces of the longitudinal rod frames 3 are provided with a plurality of groups of spaced cross rod frames 4, and the top end faces of the cross rod frames 4 are fitted with strip air cushions 5, and the cross-sectional shape of the end of the strip air cushion 5 is triangular, and the longitudinal rod frames 3 support the cross rod frames 4 to ensure the stability of the cross rod frames 4 when in use, and the cross rod frames 4 and the strip air cushions 5 can form auxiliary support for the liquid crystal glass, share most of the weight of the liquid crystal glass, and ensure the conveying While the two ends of the roller 6 will not be subjected to too much pressure, the risk of deformation and breakage in the middle area of ​​the liquid crystal glass is greatly avoided. The tops of the longitudinal rod frame 3 and the strip air cushion 5 are both convex. The strip air cushion 5 deforms when subjected to force, which expands the contact area between the strip air cushion 5 and the liquid crystal glass, and can form a good support for the liquid crystal glass. When the liquid crystal glass is broken, the pressure of the strip air cushion 5 disappears, and its top convex again, thereby ensuring that the fragments of the liquid crystal glass are not easily left on the strip air cushion 5. Similarly, the convex top of the longitudinal rod frame 3 can also achieve the same effect.

[0032] In the present embodiment, specifically, a receiving box 22 is symmetrically provided on one side of the top of the receiving slide plate 8 near the movable baffle plate 2, a rotating shaft 23 is rotatably provided inside the receiving box 22, a winding wheel 24 is sleeved on the outer side of the rotating shaft 23, a torsion spring body 25 is provided between the winding wheel 24 and the rotating shaft 23, a first bevel gear 26 is rotatably provided on the outer side of the rotating shaft 23, and the first bevel gear 26 is connected to the winding wheel 24, and the winding wheel 24 is connected to the movable baffle plate 2 through a traction rope 27, a second bevel gear 28 meshing with the first bevel gear 26 is rotatably provided on the side wall of the receiving box 22, a threaded rod body 29 is provided on the side of the second bevel gear 28 away from the first bevel gear 26, and one end of the threaded rod body 29 is rotatably connected to the inner wall of the conveying seat 1, a cleaning plate 30 matching the receiving slide plate 8 is sleeved on the outer side of the threaded rod body 29, when the staff needs to clean the liquid crystal glass fragments on the receiving slide plate 8 When collecting and cleaning, the staff can open the movable baffle 2. During the opening process of the movable baffle 2, the movable baffle 2 drives the winding wheel 24 to rotate through the traction rope 27. During the rotation of the winding wheel 24, the first bevel gear 26 can be synchronously driven to rotate. At this time, the torsion spring body 25 also deforms with the rotation of the winding wheel 24. The rotation of the first bevel gear 26 can drive the second bevel gear 28 to rotate synchronously, and the second bevel gear 28 can drive the threaded rod body 29 to rotate. Therefore, the rotation of the threaded rod body 29 can drive the cleaning plate 30 to move along the upper surface of the receiving slide plate 8, and the liquid crystal glass fragments on the receiving slide plate 8 can be pushed together, which is convenient for subsequent unified processing. When the movable baffle 2 is reset, the winding wheel 24 is flipped and reset under the action of the elastic force of the torsion spring body 25, and the threaded rod body 29 also drives the cleaning plate 30 to reset, which is convenient for next use.
