Description

Technical Field

[0001] This utility model belongs to the field of glass gripping and relates to a large-size carrier glass gripping mechanism. Background Technology

[0002] Carrier glass is a key basic material in high-tech industries such as display panel manufacturing and semiconductor packaging, and is mainly used as a carrier substrate or protective layer.

[0003] Patent (CN213568449U) discloses a glass gripping and stacking device for gripping glass on a conveyor roller and stacking the gripped glass. Its features include: a robotic gripping device, a position detection device, and a PIC controller. The robotic gripping device includes a gripping frame with a position detection device mounted on it. The position detection device detects the position of the gripped glass. The PIC controller is connected to the position detection device and the robotic gripping device. The PIC controller grips the glass based on the position information measured by the position detection device and controls the robotic gripping device to adjust its position and direction for stacking. This glass gripping and stacking device improves upon the edge-bursting issues caused by the lifting of the baffle in existing technologies and enhances the gripping efficiency of the robotic arm.

[0004] The existing technology has the following technical defects: When the above technical solution is used, although it can improve the edge breakage caused when the baffle is lifted and improve the gripping efficiency of the robot, the above equipment uses a suction cup to grip the glass. If there is dust or oil on the surface of the glass when the suction cup is adsorbing the glass, it is easy to cause the suction cup to fail to grip, or the glass may fall due to insufficient adsorption force during gripping, thus causing damage to the glass. Summary of the Invention

[0005] The technical problem this invention aims to solve is that when a suction cup adsorbs glass, dust or oil stains on the glass surface can easily cause the suction cup to fail to grasp the glass, or the glass may fall due to insufficient suction force, resulting in glass damage. This invention overcomes the shortcomings of existing technologies by providing a large-size carrier glass gripping mechanism.

[0006] The present invention discloses a large-size carrier glass gripping mechanism, comprising a frame, a gripping component disposed on the upper part of the frame, and a cleaning component disposed on the lower part of the frame on the other side.

[0007] The gripping assembly includes a drive motor A, the lower part of which is fixedly connected to the other side of the upper part of the frame. A drive gear A is fixedly connected to the output shaft of the drive motor A. A driven gear A is meshed with the lower part of the drive gear A. A threaded rod A is fixedly connected to the inner cavity of the driven gear A. One side of the threaded rod A is movably connected to the inner wall of the frame through a rotating joint. A crossbeam is fixedly connected to the inner cavity of the frame. A drive electric cylinder is provided on the upper part of the crossbeam.

[0008] The two ends of the drive cylinder are respectively fixedly connected to drive blocks. The inner cavity of one drive block is threadedly connected to the threaded rod A, and the inner cavity of the other drive block is slidably connected to a guide rod. The two sides of the guide rod are fixedly connected to the inner cavity of the frame.

[0009] A connecting plate is fixedly connected to the output shaft of the drive electric cylinder, and multiple suction cups are fixedly connected to the lower part of the connecting plate. The suction cups are connected to each other through air pipes.

[0010] The cleaning assembly includes a fixing plate disposed on the other side of the lower part of the frame. A drive motor B is fixedly connected to the upper part of the fixing plate. A drive gear B is fixedly connected to the output shaft of the drive motor B. A driven gear B is meshed with the lower part of the drive gear B. A rotating shaft is fixedly connected to the inner cavity of the driven gear B.

[0011] Both ends of the rotating shaft are fixedly connected to driving bevel gears, and the opposite sides of each driving bevel gear are meshed with driven bevel gears. The inner cavity of each driven bevel gear has a threaded groove, and the inner cavity of each threaded groove is threaded with a threaded rod B. One side of the threaded rod B is movably connected to a protective box through a rotating pair. Spraying plates are fixedly connected between opposite sides of the inner cavity of the protective box. The lower part of the spraying plate is connected to a nozzle, and the upper part of each spraying plate is connected to the same connecting pipe. A telescopic rod is fixedly connected to one side of the upper part of the protective box. The output shaft of the telescopic rod passes through the protective box, and a scraper is fixedly connected to the output shaft of the telescopic rod.

[0012] A limiting groove is formed on one side of the driven gear, and a roller is movably connected to the inner cavity of the limiting groove. A fixed rod is movably connected to one side of the roller, and one side of the fixed rod is fixedly connected to the other side of the frame.

[0013] Working process or principle: Before gripping the glass, connect the connecting pipe to the external cleaning fluid pipeline, start the drive motor B, and use the output shaft of drive motor B to drive drive gear B to rotate. Drive gear B then drives driven gear B to rotate. When driven gear B rotates, it drives the rotating shaft to move, which in turn drives two drive bevel gears to rotate. When drive bevel gears move, they drive driven bevel gears to rotate, which in turn drives the internally threaded rod B to move. The threaded rod B then moves the protective box to the top of the glass, where the nozzle sprays cleaning fluid onto the glass surface. After spraying, start the telescopic rod, and use the output shaft of the telescopic rod to move the scraper to contact the glass. When drive motor B resets the device, the scraper can scrape the cleaning fluid containing stains onto the outside of the glass. When the glass needs to be gripped, the operator places the glass into position. On the support platform below the gripping component, the air pipe is connected to the existing air pump, and the drive cylinder is activated. The output shaft of the drive cylinder drives the connecting plate to move, and the connecting plate drives the suction cup to adhere to the glass to be gripped. The suction cup then adsorbs the glass to complete the gripping. When it is necessary to move the gripped glass, the drive motor A is activated. The output shaft of the drive motor A drives the drive gear A to rotate. When the drive gear A rotates, it drives the driven gear B to rotate, and the driven gear B drives the fixed threaded rod A to rotate. When the threaded rod A rotates, it drives one of the drive blocks to move. When the drive block moves, it drives the drive cylinder to move linearly. The direction of movement of the drive cylinder is limited by the cooperation of another drive block and the guide rod, so that it can only move linearly. When the drive cylinder moves, it drives the connecting plate to move, and the connecting plate drives the glass to move.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by using the nozzle and scraper in the cleaning component together, the area to be adsorbed by the suction cup can be cleaned before the glass is gripped, thereby reducing the problem of the glass not being able to be gripped or falling off during the gripping process due to dust or oil stains adhering to the adsorption area.

[0027] During operation: When glass needs to be gripped, the operator places the glass onto the support platform located below the gripping component, connects the air pipe 12 to the existing air pump, and starts the drive cylinder 7. The output shaft of the drive cylinder 7 drives the connecting plate 10 to move, and the connecting plate 10 drives the suction cup 11 to adhere to the glass to be gripped. The suction cup 11 then adsorbs the glass to complete the gripping.

When the drive gear A3 rotates, it drives the driven gear B16 to rotate, and the driven gear B16 drives the fixed threaded rod A5 to rotate. When the threaded rod A5 rotates, it drives one of the drive blocks 8 to move. When the drive block 8 moves, it drives the drive cylinder 7 to move linearly.

After spraying is completed, start the telescopic rod 25, and use the output shaft of the telescopic rod 25 to drive the scraper 26 to move and contact the glass.
