Description

Technical Field

[0001] This invention relates to the field of liquid crystal glass handling and stacking technology, and more specifically to a liquid crystal glass handling and stacking device. Background Technology

[0002] Liquid crystal glass (LCD) is a high-tech optoelectronic glass product made by laminating liquid crystal films under high temperature and pressure. Users can control the arrangement of liquid crystal molecules by applying or removing an electric current, thereby controlling the transparency or opacity of the glass. The liquid crystal film in the middle layer serves as the functional material for dimming glass.

[0003] In the existing technology, during the production process of liquid crystal glass, robotic arms are often used for handling. The robotic arms adsorb the liquid crystal glass and place it on a customized material rack. The material rack is fixed with a support frame to separate and stack the liquid crystal glass. The staff can move the liquid crystal glass by pushing the material rack.

[0004] However, existing material racks lack limiting structures when stacking LCD glass. The material racks vibrate when handling LCD glass, which may cause the LCD glass to shift on the material rack or even slip off the material rack, thus affecting the handling efficiency of the LCD glass. Summary of the Invention

[0005] The purpose of this invention is to provide a liquid crystal glass handling and stacking device to solve the technical problem that existing material racks lack limiting structures when stacking liquid crystal glass, and the material racks vibrate when handling liquid crystal glass, which may cause the liquid crystal glass to shift on the material rack or even slip off the material rack, thus affecting the handling effect of liquid crystal glass.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution:

[0007] A liquid crystal glass handling and stacking device, comprising:

[0008] A robot, wherein a mechanical arm is fixedly connected to the top of the robot, a suction cup is fixedly connected to the bottom of the mechanical arm, and an LCD glass is attached to the bottom of the suction cup;

[0009] The base plate cooperates with the robot. Support frames are fixedly connected to the top four sides of the base plate. Several bearing plates are fixedly connected to the inner wall of the support frames along the height direction. The bearing plates have a concave cross-section and are abutted to the liquid crystal glass.

[0010] The limiting component has four sets, each of which is connected to the support frame. The limiting component is also connected to the liquid crystal glass. A drive plate is fixedly connected to the bottom of the limiting component.

[0011] As a further aspect of the present invention: support plates are fixedly connected to the four sides of the bottom plate, and rollers are connected to the inner wall of the support plates.

[0012] As a further aspect of the present invention: several buffer pads are fixedly connected at equal intervals around the inner wall of the bearing plate, the buffer pads being semi-circular in shape and cooperating with the liquid crystal glass.

[0013] As a further embodiment of the present invention: an extension tube is fixedly connected to the bottom end of the drive plate, the extension tube has a drive hole that penetrates the drive plate longitudinally, a rotating shaft is threaded into the drive hole, a servo motor is fixedly connected to the top end of the rotating shaft, and the servo motor is fixedly connected to the top end of the base plate.

[0014] As a further aspect of the present invention: a threaded hole is axially opened at the bottom of the rotating shaft, a threaded post is threadedly connected in the threaded hole, and a screw plate is fixedly connected to the bottom end of the threaded post, the inner diameter of the screw plate being larger than the diameter of the rotating shaft.

[0015] As a further embodiment of the present invention: the support frame is longitudinally provided with a sliding groove that penetrates the bottom plate, the limiting component is slidably connected to the sliding groove, and the limiting component is cooperated with the bearing plate.

[0016] As a further embodiment of the present invention: the limiting component includes: a limiting plate, a connecting seat, an adjusting rod, and a fixing seat. The limiting plate is provided in several groups and is equidistantly distributed along the height direction of the adjusting rod. The limiting plate is fixedly connected to the side end of the adjusting rod. The connecting seat is engaged in the sliding groove and is slidably connected to the inner wall of the sliding groove. A rotating groove is provided inside the sliding groove. A rotating seat is engaged in the rotating groove and is rotatably connected to the rotating seat. The rotating seat is fixedly connected to the top end of the limiting plate. The fixing seat is engaged in the sliding groove and is slidably connected to the inner wall of the sliding groove. An adjusting hole is provided longitudinally on the fixing seat. The inner wall of the adjusting hole is threadedly connected to the adjusting rod. A mating groove is provided around the bearing plate. The mating groove mates with the limiting plate.

[0017] As a further aspect of the present invention: a supporting plate is fixedly connected to the end of the limiting plate away from the adjusting rod, and a nut is fixedly connected to the bottom end of the adjusting rod.

[0018] The beneficial effects of this invention are:

[0019] 1. The robotic arm controls the suction cup to adsorb the LCD glass. The robot controls the robotic arm to move and place the LCD glass on the carrier plate. The distribution of the carrier plate on the support frame allows the LCD glass to be stacked. The shape of the carrier plate limits the LCD glass around its perimeter to prevent it from falling off the carrier plate if it shifts. The support frame is used to support the carrier plate.

[0020] 2. When the LCD glass is stacked on the carrier plate, the drive plate moves downward, which in turn moves the limiting component downward. The limiting component supports and limits the top of the LCD glass. The limiting component and the carrier plate work together to clamp the top and bottom of the LCD glass, thus ensuring that the LCD glass is stably stored on the carrier plate. When the base plate moves to transport the LCD glass, it prevents the LCD glass from shaking or tilting on the carrier plate. When the LCD glass is removed from the carrier plate, the drive plate moves upward with the limiting component, and the limiting component releases its limiting effect on the LCD glass. The robot then uses a robotic arm to drive a suction cup to pick up and transport the LCD glass. Attached Figure Description

[0032] 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.

[0033] like Figures 1-9 As shown, a liquid crystal glass handling and stacking device includes: a robot 1, a base plate 5, and a limiting assembly.

[0034] Robot 1 has a robotic arm 2 fixedly connected to its top, and a suction cup 4 fixedly connected to its bottom. The suction cup 4 has an adsorbed liquid crystal glass 3 attached to its bottom. A base plate 5 cooperates with robot 1. Support frames 8 are fixedly connected to the top four sides of the base plate 5. Several bearing plates 9 are fixedly connected to the inner wall of the support frame 8 along the height direction. The bearing plates 9 have a concave cross-section and are connected to the liquid crystal glass 3. Robot 1 controls the suction cup 4 to adsorb the liquid crystal glass 3. Robot 1 controls the robotic arm 2 to move. Robot 2 places the liquid crystal glass 3 on the bearing plates 9 by carrying it. The distribution of the bearing plates 9 on the support frame 8 allows the liquid crystal glass 3 to be stacked. The shape of the bearing plates 9 limits the movement of the liquid crystal glass 3 around its perimeter, preventing the liquid crystal glass 3 from falling off the bearing plates 9 when it shifts. The support frame 8 is used to provide support for the bearing plates 9.

[0035] The limiting components are provided in four sets and are respectively connected to the support frame 8. The limiting components are connected to the liquid crystal glass 3. The bottom end of the limiting components is fixedly connected to the drive plate 17. When the liquid crystal glass 3 is stacked on the carrier plate 9, the drive plate 17 is driven to move downward. The drive plate 17 drives the limiting components to move downward. The limiting components support and limit the top of the liquid crystal glass 3. The limiting components and the carrier plate 9 work together to clamp the upper and lower ends of the liquid crystal glass 3, thereby ensuring that the liquid crystal glass 3 is stably stored on the carrier plate 9. When the bottom plate 5 moves to transport the liquid crystal glass 3, it prevents the liquid crystal glass 3 from shaking and tilting on the carrier plate 9. When the liquid crystal glass 3 is removed from the carrier plate 9, the drive plate 17 moves upward with the limiting components. The limiting components release the limiting effect on the liquid crystal glass 3. The robot 1 drives the suction cup 4 through the robotic arm 2 to pick up and transport the liquid crystal glass 3.

[0036] In some specific implementations, support plates 6 are fixedly connected to the four sides of the base plate 5. Rollers 7 are connected to the inner wall of the support plates 6. When the base plate 5 moves, the base plate 5 rotates along the ground via the rollers 7. The rollers 7 rotate along the inner wall of the support plates 6. When the liquid crystal glass 3 is placed on the base plate 5, the rollers 7 can be locked and fixed by the support plates 6. The support provided by the rollers 7 is transmitted to the base plate 5 through the support plates 6.

[0037] In some specific implementations, several buffer pads 11 are fixedly connected at equal intervals around the inner wall of the support plate 9. The buffer pads 11 are semi-circular in shape and cooperate with the liquid crystal glass 3. When the liquid crystal glass 3 is placed on the support plate 9, the liquid crystal glass 3 and the buffer pads 11 abut against each other. When the base plate 5 moves, the vibration generated by the base plate 5 is transmitted to the support plate 9. The inner wall of the support plate 9 can be fixed with existing shock-absorbing pads to buffer the vibration. The buffer pads 11 limit the edge of the liquid crystal glass 3 and buffer the vibration to prevent the vibration from being transmitted to the edge of the liquid crystal glass 3. It should be noted that the support plate 9 can be fixed to the support frame 8 with existing bolts. When the support plate 9 needs to be replaced, it is convenient to remove and install the support plate 9 from the support frame 8.

[0038] In some specific implementations, an extension tube 24 is fixedly connected to the bottom end of the drive plate 17. The extension tube 24 has a longitudinally extending drive hole 25 that penetrates the drive plate 17. A rotating shaft 16 is threadedly connected to the drive hole 25. A servo motor 15 is fixedly connected to the top end of the rotating shaft 16 and is fixedly connected to the top end of the base plate 5. A threaded hole 28 is axially opened at the bottom of the rotating shaft 16. A threaded post 27 is threadedly connected to the threaded hole 28. A screw plate 26 is fixedly connected to the bottom end of the threaded post 27. The inner diameter of the screw plate 26 is larger than the diameter of the rotating shaft 16. When the drive plate 17 needs to move in height, the servo motor 15 operates, driving the rotating shaft 16 to rotate. The rotating shaft 16 moves the drive plate 17 through the threaded connection with the drive hole 25, thus limiting its movement. The component, in cooperation with the support frame 8, ensures that the drive plate 17 does not rotate. The extension tube 24 extends the threaded connection path between the rotating shaft 16 and the drive plate 17, preventing the drive hole 25 on the drive plate 17 from failing due to threaded connection failure after prolonged operation, which would cause the drive plate 17 to malfunction. It should be noted that when the drive plate 17 moves downward, the screw plate 26 limits the drive plate 17, preventing the limit component from falling off due to improper operation of the drive plate 17. When the servo motor 15 needs to be removed for maintenance, the screw plate 26 is controlled to rotate. The screw plate 26, along with the threaded post 27, rotates within the threaded hole 28, and the screw plate 26 is removed from the rotating shaft 16, thereby achieving the effect of removing and maintaining the servo motor 15.

[0039] In some specific implementations, the support frame 8 has a longitudinally extending groove 13 that penetrates the base plate 5. The limiting component is slidably connected to the groove 13 and is connected to the bearing plate 9. The groove 13 on the support frame 8 facilitates the limiting component to provide a limiting guide.

[0040] In some specific embodiments, the limiting assembly includes: a limiting plate 10, a connecting seat 12, an adjusting rod 18, and a fixing seat 21. The limiting plate 10 has several sets of components equidistantly distributed along the height direction of the adjusting rod 18. The limiting plate 10 is fixedly connected to the side end of the adjusting rod 18. The connecting seat 12 is engaged within the slide groove 13 and slidably connected to the inner wall of the slide groove 13. A rotating groove 19 is provided inside the slide groove 13. A rotating seat 20 is engaged within the rotating groove 19 and rotatably connected to the rotating seat 20. The rotating seat 20 is fixedly connected to the top end of the limiting plate 10. The fixing seat 21 is engaged within the slide groove 13 and slidably connected to the inner wall of the slide groove 13. The fixed base 21 has an adjustment hole 22 longitudinally, and the inner wall of the adjustment hole 22 is threadedly connected to the adjustment rod 18. The bearing plate 9 has mating grooves 29 on all four sides, which mate with the limiting plate 10. A support plate 30 is fixedly connected to the end of the limiting plate 10 away from the adjustment rod 18. A nut 23 is fixedly connected to the bottom end of the adjustment rod 18. When the drive plate 17 moves downwards with the limiting assembly, the drive plate 17 moves the fixed base 21 along the inner wall of the slide groove 13. The fixed base 21 moves along the inner wall of the slide groove 13 with the connecting seat 12 via the adjustment rod 18. The adjustment rod 18 moves the limiting plate 10 into the slide groove 13. The limiting plate 10 and the supporting plate 30, which are fixed to the limiting plate 10, support and limit the top of the liquid crystal glass 3. The limiting plate 10 and the supporting plate 30 are plastic to prevent damage to the liquid crystal glass 3 when supporting it. The connecting seat 12 and the fixing seat 21 are connected to the sliding groove 13 to provide a limiting function for the adjusting rod 18, preventing the adjusting rod 18 from tilting in the vertical direction. When the size of the liquid crystal glass 3 changes, the liquid crystal glass 3 and the buffer pad 11 are supported. The control nut 23 rotates the adjusting rod 18, which drives the limiting plate 10 and the supporting plate 30 to rotate. The adjustment rod 18, with its top end carrying the rotating seat 20, rotates along the inner wall of the rotating groove 19, thereby ensuring that the limiting plate 10 and the supporting plate 30 can support the liquid crystal glass 3. The adjustment rod 18 is fixed by a threaded connection with the adjustment hole 22, thereby ensuring that when the fixed seat 21 moves vertically, the adjustment rod 18 moves with the fixed seat 21. The rotating seat 20 and the rotating groove 19 are connected by a snap-fit ​​connection, connecting the top end of the adjustment rod 18 and the connecting seat 12 together. The matching groove 29 prevents the limiting plate 10 from not fitting the bearing plate 9 when the adjustment rod 18 is rotated for adjustment.

[0041] The foregoing has described several embodiments of the present invention in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of the invention. All equivalent variations and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
