Description

Technical Field

[0001] The present application belongs to the field of carrier glass production, and in particular relates to a carrier glass longitudinal turning system. Background Art

[0002] Carrier glass is mainly used as the substrate of display screens. It needs to go through multiple processes such as melting, forming, cooling, cutting, polishing, etc., and finally the carrier glass is subjected to various tests before the production of carrier glass is completed.

[0003] The inspection of carrier glass mainly includes surface crack inspection, flatness inspection, light transmission inspection, etc. Some inspections, such as surface defect inspection and flatness inspection, require the carrier glass to be flipped over for double-sided inspection. Traditional carrier glass flipping usually adds a separate station, that is, after one side is inspected, it is transferred to the flipping table to be turned over, and then transferred to the next inspection station to inspect the other side. The flipping cannot be completed at the same inspection station, which not only has low efficiency, but also high equipment cost.

[0004] Therefore, a turning table for testing carrier glass is needed to solve the above problems. Summary of the invention

[0005] In order to solve the deficiencies of the prior art, the present application provides a longitudinal flipping system for carrier glass, which can drive the carrier glass to automatically flip over for inspection, thereby improving efficiency and reducing costs.

[0006] The technical effects to be achieved by this application are achieved through the following solutions:

[0007] According to the first aspect of the present application, a longitudinal flipping system for carrier glass is provided, comprising a conveying roller, a flipping roller and a gripping mechanism connected in sequence, wherein both sides of the flipping roller are rotatably connected to a flipping bracket, and the flipping roller is driven to rotate by a flipping motor; the flipping roller comprises two upper and lower rows of support rollers, wherein the center line between the two rows of support rollers is flush with the conveying roller, and the support rollers are driven by a clamping mechanism to clamp the carrier glass; the gripping mechanism is used to grip the carrier glass onto the flipping roller and convey the carrier glass onto the conveying roller.

[0008] Through this solution, the structure of the device is simple and compact, and can be directly placed at the inspection station. The carrier glass is input to the flip roller for inspection through the conveyor roller. After the front inspection is completed, the flip roller is controlled to rotate 180 degrees to complete the flip. After the back inspection is completed, the carrier glass can be controlled to be transported away under the driving device of the gripping mechanism.

[0009] Preferably, the clamping mechanism comprises a driving cylinder and a mounting plate, the support rollers in the same row are all mounted on the same mounting plate, and the driving cylinder drives the mounting plate to move away from or close to the carrier glass.

[0010] Through this solution, the clamping mechanism can clamp the carrier glass with the supporting roller to prevent the carrier glass from falling during the flipping process.

[0011] Preferably, an inner side wall of the turning roller is provided with a receiving groove, and the driving cylinder drives the supporting roller to extend axially into or retract into the receiving groove.

[0012] Through this solution, the support roller can release the carrier glass after retracting into the accommodating groove, which facilitates its transportation and avoids collision between the extended support roller and the carrier glass; and the retracted support roller can avoid blocking both sides of the carrier glass, thereby improving the reliability of detection.

[0013] Preferably, the supporting roller is a conical structure, and the driving cylinder always drives the supporting roller located above the carrier glass to extend to fix the carrier glass or retract to release the carrier glass.

[0014] Through this solution, the supporting roller with a conical structure can move along with the axial movement to gradually squeeze and fix the carrier glass, which is suitable for products of different thicknesses and improves the scope of application.

[0015] Preferably, the flip motor is drivingly connected to the rotating shaft of the flip roller via a synchronous belt, and the flip motor is a servo motor.

[0016] Through this solution, the servo motor can improve the rotation accuracy and ensure that the carrier glass can accurately enter and exit the flip roller.

[0017] Preferably, the rotating shaft is a hollow structure and is connected to the accommodating groove. A driving rod is fixed on the mounting plate, the driving rod extends through the rotating shaft, the driving cylinder is rotatably connected to the end of the driving rod through a connecting block, and the driving cylinder is fixed to the flip bracket.

[0018] Through this solution, since the driving rod is located at the rotating shaft, its position relative to the flipping bracket is relatively fixed, which facilitates the fixed arrangement of the driving cylinder and avoids the line distortion and damage caused by the rotation of the driving cylinder; and this method can reduce the volume of the flipping part, making it convenient to place the device in the detection station.

[0019] Preferably, the driving rods on the two mounting plates are combined to form a cylindrical shape, and semicircular driving blocks are provided at the ends of the driving rods. The semicircular driving blocks are combined to form a circle and are rotatably connected to the connecting block.

[0020] Through this solution, the driving rod assembly is formed into a cylindrical shape, which can facilitate its rotation in the rotating shaft without colliding with the connecting block, thereby reducing friction and improving smoothness during operation.

[0021] Preferably, a connecting cavity is provided in the connecting block, the driving block is rotatably connected to the connecting cavity, a driving portion protruding downward is provided on the top of the connecting cavity, and the driving portion is hooked to the driving block.

[0022] Through this solution, as the driving block rotates, the driving part is located at a fixed position, and can always drive the top supporting roller to move, thereby releasing the carrier glass, and the structure is simple and reliable.

[0023] Preferably, the piston rod of the driving cylinder is connected to the middle of the driving plate, the connecting block is fixed to the top of the driving plate, and a smooth rod is provided at the bottom of the driving plate, and the smooth rod is slidably connected to the flip bracket.

[0024] Through this solution, the polished rod and the drive cylinder can stabilize the movement of the drive plate and improve its reliability.

[0025] Preferably, the gripping mechanism includes a longitudinal cylinder, a vertical cylinder and a suction cup. The longitudinal cylinder is a servo electric cylinder and its length is greater than the length of the flip roller. The vertical cylinder is installed to the end of the piston rod of the longitudinal cylinder, and the suction cup is fixed to the bottom of the piston rod of the vertical lever.

The vertical cylinder can extend and retract up and down to release and grab the carrier glass.

[0027] According to one embodiment of the present application, the beneficial effect of using the longitudinal flipping system for the carrier glass is that the structure is compact and simple, and it can be directly installed in the inspection station for front and back side inspection without adding additional stations, thereby reducing equipment costs and improving inspection efficiency.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0038] like Figures 1 to 8 As shown, the longitudinal flipping system of the carrier glass in one embodiment of the present application includes a conveying roller 20, a flipping roller 10 and a gripping mechanism 30 connected in sequence, the two sides of the flipping roller 10 are rotatably connected to the flipping bracket 110, and the flipping roller 10 is driven to rotate by a flipping motor 140; the flipping roller 10 includes two upper and lower rows of support rollers 120, and the center line between the two rows of support rollers 120 is flush with the conveying roller 20, and the support rollers 120 are driven by a clamping mechanism 130 to clamp the carrier glass; the gripping mechanism 30 is used to grab the carrier glass onto the flipping roller 10 and convey the carrier glass to the conveying roller 20.

[0039] Through the scheme of this embodiment, the structure of the device is simple and compact, and can be directly placed at the inspection station. The carrier glass is input to the flip roller 10 for inspection through the conveying roller 20. After the front inspection is completed, the flip roller 10 is controlled to rotate 180 degrees to complete the flip. After the direct back inspection is completed, the carrier glass can be controlled to be transported away under the driving device of the gripping mechanism 30.

[0040] The flip roller 10 is a rectangular frame, and the support rollers 120 are installed on both sides of the rectangular frame. The front and rear sides of the rectangular frame are opening structures for inputting and outputting the carrier glass; the opening of the frame can allow the grabbing mechanism 30 to enter and exit to ensure that the carrier glass can be grabbed for transfer.

[0041] In one embodiment of the present application, the clamping mechanism 130 includes a drive cylinder 131 and a mounting plate 122. The support rollers 120 in the same row are all mounted on the same mounting plate 122. The drive cylinder 131 drives the mounting plate 122 to move away from or close to the carrier glass. The clamping mechanism 130 can clamp the support rollers 120 to the carrier glass to prevent the carrier glass from falling during the flipping process.

[0042] In one embodiment of the present application, the inner side wall of the turning roller 10 is provided with a receiving groove 121, and the driving cylinder 131 drives the supporting roller 120 to extend or retract the receiving groove 121 in the axial direction. After the supporting roller 120 is retracted into the receiving groove 121, the carrier glass can be released, which is convenient for conveying the supporting roller 120 and avoiding collision between the extended supporting roller 120 and the carrier glass; and the retracted supporting roller 120 can avoid blocking both sides of the carrier glass, thereby improving the reliability of detection.

[0043] When the carrier glass is conveyed onto the flip roller 10, the upper row of support rollers 120 are controlled to retract to facilitate the movement of the carrier glass. When the carrier glass reaches the position, the front side inspection is performed. After the front side inspection is completed, the upper support rollers 120 are controlled to extend to clamp the carrier glass. After the flip roller 10 rotates, the support rollers 120 are controlled to retract to perform the reverse side inspection.

[0044] In one embodiment of the present application, the support roller 120 is a conical structure, and the drive cylinder 131 always drives the support roller 120 located above the carrier glass to extend to fix the carrier glass or retract to release the carrier glass. The support roller 120 with a conical structure can move along with the axial movement, and can gradually squeeze and fix the carrier glass, which is suitable for products of different thicknesses and improves the scope of application. The support roller 120 is coated with a rubber layer. The support roller 120 is prevented from damaging the carrier glass, and the safety during use is improved.

[0045] In one embodiment of the present application, the flip motor 140 is connected to the rotating shaft 101 of the flip roller 10 through a synchronous belt, and the flip motor 140 is a servo motor. The servo motor can improve the rotation accuracy and ensure that the carrier glass can accurately enter and exit the flip roller 10.

[0046] In one embodiment of the present application, the rotating shaft 101 is a hollow structure and is connected to the containing groove 121. A driving rod 123 is fixed on the mounting plate 122. The driving rod 123 extends through the rotating shaft 101. The driving cylinder 131 is rotatably connected to the end of the driving rod 123 through a connecting block 133. The driving cylinder 131 is fixed to the flip bracket 110. Since the driving rod 123 is located at the rotating shaft 101, its position relative to the flip bracket 110 is relatively fixed, thereby facilitating the fixed arrangement of the driving cylinder 131 and avoiding the line distortion and damage caused by the rotation of the driving cylinder 131. Moreover, this method can reduce the volume of the flipping part, making it convenient for the device to be placed in the detection station.

[0047] In one embodiment of the present application, the driving rods 123 on the two mounting plates 122 are combined to form a cylindrical shape, and a semicircular driving block 124 is provided at the end of the driving rod 123. The semicircular driving block 124 is combined to form a circle and is rotatably connected to the connecting block 133. The driving rod 123 is combined to form a cylindrical shape, which can facilitate its rotation in the rotating shaft 101 without colliding with the connecting block 133, reducing friction and improving smoothness during work.

[0048] In one embodiment of the present application, a connection cavity 1331 is provided in the connection block 133, the driving block 124 is rotatably connected to the connection cavity 1331, a driving portion 1332 protruding downward is provided at the top of the connection cavity 1331, and the driving portion 1332 is hooked to the driving block 124. As the driving block 124 rotates, the driving portion 1332 is located in a fixed position, and can always drive the top support roller 120 to move, thereby releasing the carrier glass, and the structure is simple and reliable.

[0049] In one embodiment of the present application, the piston rod of the driving cylinder 131 is connected to the middle of the driving plate 132, the connecting block 133 is fixed to the top of the driving plate 132, and a light rod 134 is provided at the bottom of the driving plate 132, and the light rod 134 is slidably connected to the flip bracket 110. The light rod 134 and the driving cylinder 131 can stabilize the movement of the driving plate 132 and improve its reliability.

[0050] The grabbing mechanism 30 in this embodiment includes a longitudinal cylinder 310, a vertical cylinder 320 and a suction cup 321. The longitudinal cylinder 310 is a servo electric cylinder and its length is greater than the length of the flip roller 10. It can stop at the corresponding position for grabbing and releasing as needed. The vertical cylinder 320 is installed to the end of the piston rod of the longitudinal cylinder 310. The suction cup 321 is fixed to the bottom of the piston rod of the vertical lever, which can drive the suction cup 321 to move vertically, thereby grabbing and releasing the carrier glass. The longitudinal cylinder 310 can move to the conveying roller 20 to grab the carrier glass onto the flip roller 10, and can also push the carrier glass on the flip roller 10 back to the conveying roller 20. The vertical cylinder 320 can extend and retract up and down to release and grab the carrier glass.

[0051] In order to improve the reliability of grasping and releasing of the suction cup 321, a negative pressure air pipe may be connected to the top of the suction cup 321, and air is extracted or blown into the suction cup 321 by the air pipe to achieve the grasping and releasing effects.
