A re-inspection conveying mechanism for liquid crystal glass

Abstract

This invention discloses a re-inspection conveying mechanism for liquid crystal glass, relating to the field of liquid crystal glass re-inspection technology. It includes a conveyor base with a sliding receiving plate inside to capture and collect falling liquid crystal glass fragments. When a glass fragment lands on the receiving plate, its weight causes the plate to slide downwards, compressing the main air bladder below. Under pressure, the main air bladder deforms and collapses, causing the gas inside to be guided through a connecting pipe into a receiving sleeve. This process triggers the upward movement of a piston rod and a top block. The upward movement of the top block effectively lifts the liquid crystal glass fragments stuck between the conveyor rollers, ensuring the normal operation of the conveyor rollers, preventing scratches caused by glass fragments, improving the safety and reliability of the entire conveying system, reducing the need for manual intervention, lowering maintenance costs, and increasing production efficiency.

Description

Technical Field

[0001] This invention relates to the field of liquid crystal glass re-inspection technology, and more specifically to a re-inspection conveying mechanism for liquid crystal glass. Background Technology

[0002] Liquid crystal glass is a high-tech optoelectronic glass product made by laminating and encapsulating liquid crystal films under high temperature and pressure. It is a core component of liquid crystal displays. It uses the electro-optic effect of liquid crystal molecules to control the passage of light, thereby realizing the display of images. After the initial inspection of liquid crystal glass is completed, a second inspection is often required. By taking two photos, the quality inspection effect of the product is further improved.

[0003] Chinese Patent Publication No. CN105417166A, entitled "A Defect-Removing Conveying Device for Liquid Crystal Glass Substrates," includes a roller conveying unit, a vacuum handling unit, a CCD camera, a lifting platform, and a control box. Two lifting platforms are located on either side of the roller conveying unit. The CCD camera and vacuum handling unit are both located directly above the roller conveying unit. The control box is electrically connected to the CCD camera and vacuum handling unit. The roller conveying unit is used for non-destructive conveying of the liquid crystal glass substrates. The CCD camera is used to photograph the liquid crystal glass substrates to identify whether defective products are present. The vacuum handling unit is used to pick up qualified and defective products and place them in different positions, thereby achieving automatic differentiation between qualified and defective liquid crystal glass substrates and avoiding the low accuracy and efficiency of manual identification.

[0004] Although the aforementioned patent can automatically distinguish between qualified and defective liquid crystal glass substrates during transportation, the liquid crystal glass may break due to uneven force or vibration during transportation. The broken liquid crystal glass is easy to get stuck in the transport roller, which not only hinders the normal rotation of the transport roller, but also easily scratches the transport roller, causing some inconvenience to the normal use of the device. Summary of the Invention

[0005] The purpose of this invention is to provide a re-inspection conveying mechanism for liquid crystal glass, so as to solve the technical problem in the prior art that broken liquid crystal glass is easily stuck in the conveying roller of the liquid crystal glass re-inspection conveying mechanism, which hinders the normal rotation of the conveying roller.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A re-inspection conveying mechanism for liquid crystal glass includes a conveyor base and several sets of spaced conveyor rollers disposed on the inner walls of both sides of the conveyor base.

[0008] It also includes a cleaning assembly installed on the conveyor seat; wherein the cleaning assembly includes a main airbag body and a receiving slide plate installed inside the conveyor seat, with the receiving slide plate slidably distributed above the main airbag body, several sets of spaced-apart supporting air pipes installed on the inner walls of both sides of the conveyor seat, a receiving sleeve installed at one end of the supporting air pipe, a piston rod slidably installed inside the receiving sleeve, a top block installed at the top of the piston rod and the top block being located between the conveyor rollers, and connecting pipes installed on both sides of the conveyor seat for connecting the main airbag body and the supporting air pipes.

[0009] As a further aspect of the present invention: the inner walls on both sides of the conveyor seat are provided with grooves for limiting the receiving slide plate, the top end face of the receiving slide plate is concave downward from both sides, its cross-section is V-shaped, and the top block is a right triangle with its inclined surface facing upward.

[0010] As a further aspect of the present invention: the two ends of the conveyor seat are provided with longitudinal rods, and the longitudinal rods are located above the receiving slide plate. The top end face of the longitudinal rods protrudes upward from both sides. The top end face of the longitudinal rods is provided with several sets of spaced horizontal rods. The top end face of the horizontal rods is fitted with a strip-shaped air cushion, and the end cross-sectional shape of the strip-shaped air cushion is triangular.

[0011] As a further aspect of the present invention: the inner walls on both sides of the delivery seat are provided with several sets of spaced side racks, the interior of the top block is divided into an airbag cavity and an active cavity by a partition plate, the airbag cavity is provided with an auxiliary airbag body and a pressure plate, and the pressure plate is slidably distributed on both sides of the auxiliary airbag body.

[0012] As a further aspect of the present invention: air grooves communicating with the movable cavity are provided on both sides of the top block. The air grooves are connected to the output end of the auxiliary air bag through a flexible air tube. A bidirectional lead screw matching the pressure plate is rotatably installed inside the movable cavity. A drive gear is provided in the middle of the bidirectional lead screw. When the top block rises, the drive gear meshes with the side rack and rotates.

[0013] As a further aspect of the present invention: a receiving box is symmetrically arranged on the side of the top of the receiving slide near the movable baffle, a rotating shaft is rotatably arranged inside the receiving box, a winding wheel is sleeved on the outside of the rotating shaft, a torsion spring is arranged between the winding wheel and the rotating shaft, and a first bevel tooth is rotatably arranged on the outside of the rotating shaft, and the first bevel tooth is connected to the winding wheel.

[0014] As a further embodiment of the present invention: the winding reel is connected to the movable baffle via a traction rope, the side wall of the receiving box is rotatably provided with a second bevel tooth that meshes with the first bevel tooth, a threaded rod is provided on the side of the second bevel tooth away from the first bevel tooth, and one end of the threaded rod is rotatably connected to the inner wall of the conveying seat, and a cleaning plate matching the receiving slide plate is sleeved on the outer side of the threaded rod.

[0015] As a further embodiment of the present invention: the platform of the conveyor seat is movably provided with a movable truss, and a movable seat is even movably provided on the movable truss. A re-inspection module for taking pictures of the liquid crystal glass is provided on the movable seat, and a support base is provided at the bottom of the conveyor seat.

[0016] The beneficial effects of this invention are:

[0017] 1. In this invention, a receiving slide plate is slidably installed inside the conveyor seat to capture and collect falling liquid crystal glass fragments. When a glass fragment falls onto the receiving slide plate, its weight causes the slide plate to slide downwards, thereby squeezing the main airbag below. The main airbag deforms and collapses under pressure, causing the gas inside to be guided into a receiving sleeve through a connecting pipe. This process triggers the upward movement of the piston rod and the top block. The upward movement of the top block can effectively lift the liquid crystal glass fragment stuck between the conveyor rollers, which not only ensures the normal operation of the conveyor rollers and avoids scratches caused by glass fragments, but also improves the safety and reliability of the entire transportation system, reduces the need for manual intervention, lowers maintenance costs, and improves production efficiency.

[0018] 2. In this invention, when the top block rises, the drive gear and the side rack mesh and rotate. The rotation of the drive gear drives the bidirectional lead screw to rotate, and the bidirectional lead screw drives the pressure plates to move closer to each other to squeeze the auxiliary airbag. The gas in the auxiliary airbag is blown out through the soft air tube and air groove, thereby pneumatically cleaning the small liquid crystal glass fragments remaining on the conveyor roller, reducing the workload of subsequent workers.

[0019] 3. In this invention, when the movable baffle is opened, the operator can drive the winding wheel and the first bevel gear to rotate by the traction rope. The first bevel gear drives the second bevel gear and the threaded rod to rotate synchronously. The rotation of the threaded rod can drive the cleaning plate to move along the upper surface of the receiving slide plate, and push the liquid crystal glass fragments on the receiving slide plate together for easy subsequent unified processing.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1-6 As shown, a re-inspection conveying mechanism for liquid crystal glass includes a conveying base 1 and several sets of spaced conveying rollers 6 disposed on the inner walls of both sides of the conveying base 1. A movable truss 31 is movably disposed on the platform of the conveying base 1, and a movable seat 32 is movably disposed on the movable truss 31. A re-inspection module 33 for photographing the liquid crystal glass is disposed on the movable seat 32. A support base 34 is disposed at the bottom of the conveying base 1. The conveying rollers 6 support both sides of the liquid crystal glass and transport it. The re-inspection module 33 is used to photograph and re-inspect the liquid crystal glass.

[0030] It also includes a cleaning assembly mounted on the conveyor seat 1; wherein the cleaning assembly includes a main airbag 7 and a receiving slide plate 8 disposed inside the conveyor seat 1, and the receiving slide plate 8 is slidably distributed above the main airbag 7. The inner walls on both sides of the conveyor seat 1 are provided with grooves for limiting the receiving slide plate 8. The top end face of the receiving slide plate 8 is concave downward from both sides, and its cross-section is V-shaped. Several sets of spaced-apart support air pipes 9 are disposed on the inner walls on both sides of the conveyor seat 1. A receiving sleeve 10 is disposed at one end of the support air pipe 9. A piston rod 11 is slidably disposed inside the receiving sleeve 10. A top block 12 is disposed at the top of the piston rod 11. The top block 12 is right-angled triangular in shape and inclined towards the top. The top block 12 is located between the conveying rollers 6 and is arranged on both sides of the conveying seat 1. It is a connecting pipe 21 for connecting the main airbag body 7 and the supporting air pipe 9. Several sets of spaced side racks 13 are provided on the inner walls of both sides of the conveying seat 1. The interior of the top block 12 is divided into an airbag cavity and a movable cavity by a partition plate 14. The airbag cavity is provided with an auxiliary airbag body 15 and a pressure plate 16. The pressure plate 16 is slidably distributed on both sides of the auxiliary airbag body 15. The top block 12 has air grooves 17 on both sides that communicate with the movable cavity. The air grooves 17 are connected to the output end of the auxiliary airbag body 15 through a flexible air pipe 18. The movable cavity is rotatably provided with a bidirectional screw 19 that matches the pressure plate 16. A drive gear 20 is installed in the middle. When the top block 12 rises, the drive gear 20 meshes with the side rack 13 and rotates. When the liquid crystal glass breaks during transportation, most of the liquid crystal glass fragments will fall onto the receiving slide plate 8. The end face of the receiving slide plate 8 is concave downwards from both sides, causing the liquid crystal glass fragments that fall onto it to slide downwards under their own gravity and accumulate in the central area of ​​the receiving slide plate 8, which is convenient for subsequent cleaning. At this time, the gravity on the receiving slide plate 8 increases, and it begins to slide downwards along the slide groove, compressing the main airbag 7. The main airbag 7 deforms and collapses under pressure. At this time, the gas inside the main airbag 7 is introduced into the storage through the connecting pipe 21. Inside the sleeve 10, the piston rod 11 and the top block 12 are driven to move upward. The rise of the top block 12 can lift the liquid crystal glass fragments stuck between the conveying rollers 6, thus ensuring the normal rotation of the conveying rollers 6. When the top block 12 rises, the drive gear 20 and the side rack 13 mesh and rotate. The rotation of the drive gear 20 drives the bidirectional lead screw 19 to rotate. The bidirectional lead screw 19 drives the pressure plates 16 to move closer to each other and squeeze the auxiliary air bladder 15. The gas in the auxiliary air bladder 15 is blown out through the flexible air tube 18 and the air groove 17, thereby pneumatically cleaning the small liquid crystal glass fragments remaining on the conveying rollers 6 and reducing the workload of subsequent workers.

[0031] In this embodiment, specifically, longitudinal rods 3 are mounted at both ends of the conveyor seat 1, and the longitudinal rods 3 are located above the receiving slide plate 8. The top end face of the longitudinal rods 3 protrudes upward from both sides. Several sets of spaced-apart crossbars 4 are provided on the top end face of the longitudinal rods 3. Strip-shaped air cushions 5 are attached to the top end face of the crossbars 4, and the cross-sectional shape of the end of the strip-shaped air cushions 5 is triangular. The longitudinal rods 3 support the crossbars 4, ensuring the stability of the crossbars 4 during use. The crossbars 4 and the strip-shaped air cushions 5 can provide auxiliary support for the liquid crystal glass, sharing most of the weight of the liquid crystal glass and ensuring the smooth conveying. While the ends of roller 6 do not bear 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 designed to be raised. When the strip air cushion 5 is subjected to force, it deforms, which increases the contact area between the strip air cushion 5 and the liquid crystal glass, and can provide good support for the liquid crystal glass. When the liquid crystal glass breaks, the pressure of the strip air cushion 5 disappears, and its top rises again. This ensures that the fragments of the liquid crystal glass are not easily left on the strip air cushion 5. Similarly, the raised top of the longitudinal rod frame 3 can also achieve the same effect.

[0032] In this embodiment, specifically, a receiving box 22 is symmetrically arranged on the top of the receiving slide plate 8 near the movable baffle 2. A rotating shaft 23 is rotatably arranged inside the receiving box 22. A winding wheel 24 is sleeved on the outer side of the rotating shaft 23. A torsion spring 25 is arranged between the winding wheel 24 and the rotating shaft 23. A first bevel tooth 26 is rotatably arranged on the outer side of the rotating shaft 23, and the first bevel tooth 26 is connected to the winding wheel 24. The winding wheel 24 is connected to the movable baffle 2 via a traction rope 27. A second bevel tooth 28 is rotatably arranged on the side wall of the receiving box 22, meshing with the first bevel tooth 26. A threaded rod 29 is arranged on the side of the second bevel tooth 28 away from the first bevel tooth 26, and one end of the threaded rod 29 is rotatably connected to the inner wall of the conveyor seat 1. A cleaning plate 30 matching the receiving slide plate 8 is sleeved on the outer side of the threaded rod 29. When the operator needs to clean the liquid crystal glass fragments on the receiving slide plate 8... During collection and cleaning, staff can open the movable baffle 2. As the baffle 2 opens, it drives the take-up reel 24 to rotate via the traction rope 27. The rotation of the take-up reel 24 synchronously drives the first bevel tooth 26 to rotate. At this time, the torsion spring 25 also deforms with the rotation of the take-up reel 24. The rotation of the first bevel tooth 26 drives the second bevel tooth 28 to rotate synchronously. The second bevel tooth 28 drives the threaded rod 29 to rotate. Thus, the rotation of the threaded rod 29 drives the cleaning plate 30 to move along the upper surface of the receiving slide plate 8, which can gather and push the liquid crystal glass fragments on the receiving slide plate 8 together for subsequent unified processing. When the movable baffle 2 resets, the take-up reel 24 flips and resets under the elastic force of the torsion spring 25. The threaded rod 29 then drives the cleaning plate 30 to reset, making it convenient for the next use.

[0033] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
