Description

Technical Field

[0001] The utility model relates to the field of display screen production, and more specifically, to a glass plate transfer rack. Background Art

[0002] During the display production process, after the glass plate of the inner or outer screen is processed to the desired size, it needs to be transferred to the next station for further processing.

[0003] Most of the existing glass plate transfer racks are ordinary iron racks, and the glass plates are placed on the buffer pads on the iron racks for transfer. Especially in the process of transferring large glass plates, due to their heavy weight, the bumps during the transfer process may cause them to slip during the transfer process; some transfer racks will be equipped with suction cups on the iron racks, and the suction of the suction cups will be used to keep the glass plates stable, but the suction of the current suction cups is limited. During the transfer process, the glass plates will still be slowly released due to excessive gravity and bumps. If an electric pump or other device is added to improve the reliability of the suction cup, the cost and weight of the transfer rack will be greatly increased; although placing the glass plate horizontally can reduce the drop caused by bumps, the horizontal placement takes up a lot of space, which is inconvenient for the transfer and manual pushing of the glass plates.

[0004] Therefore, a novel glass plate transfer rack is needed to solve the above problems. Utility Model Content

[0005] One purpose of the utility model is to solve the problem that the existing glass plate transfer mechanism tends to occupy a large space or the glass plate tends to fall due to bumps.

[0006] According to one aspect of the utility model, a glass plate transfer rack is provided, including a chassis and a frame body, wherein the frame body is installed on the chassis, rollers are arranged at the bottom of the chassis, a plurality of suction cups are arranged on the frame body, the bottom middle of the frame body is hingedly connected to the chassis, and a baffle frame is arranged at the front bottom of the frame body.

[0007] Through this solution, the hinged frame can make it convenient to load the glass plate in a horizontal state, and the suction cup can fix the glass plate. During transportation, the frame can be flipped to an inclined state or 90°, which is convenient for reducing the front and rear occupied space and facilitating pushing and transportation; the bottom baffle can support the glass plate, avoid the weight of the glass plate from having a greater impact on the suction cup, greatly reduce the burden on the suction cup, and the suction cup only needs to prevent the glass plate from tipping forward, thereby greatly improving reliability.

[0008] Preferably, the baffle is rotatably connected to the end of the frame body, and the baffle comprises a baffle plate and a leg. When the leg abuts against the chassis, the baffle plate is perpendicular to the frame body.

[0009] Through this solution, the rotation of the baffle can facilitate the placement of the glass plate and avoid bumping the glass plate caused by the protruding baffle when placing it; and the flipped baffle can adapt to the different placement heights of the glass plate, and the baffle can still hold the glass plate when the placement position is too low.

[0010] Preferably, the suction cup is connected to the frame through an elastic mechanism, and the elastic mechanism is used for the suction cup to elastically move along the frame.

[0011] Through this solution, the elastic mechanism can achieve fine adjustment of the position of the suction cup. When the glass plate is placed on the suction cup, the inclination of the frame can make the glass plate move downward under its own gravity and abut against the retaining frame.

[0012] Preferably, the elastic mechanism includes a slider and a spring, the slider is slidably connected to a slide groove of the frame, the spring is arranged at one end of the slide groove facing the retaining frame, and the suction cup is connected to the slider.

[0013] Through this solution, after the glass plate is moved away, the spring can push the suction cup to move upward and reset.

[0014] Preferably, the suction cup is connected with a negative pressure tube, and the negative pressure tube is connected to a foot-operated negative pressure mechanism, and the foot-operated negative pressure mechanism is used to provide negative pressure for the suction cup.

[0015] Through this solution, negative pressure is manually provided to the suction cup by pedaling, which is not only convenient to operate but also has lower costs.

[0016] Preferably, the foot-operated negative pressure mechanism includes a negative pressure cylinder, a piston and a foot pedal, the piston is connected to the negative pressure cylinder, the negative pressure tube is connected to the negative pressure cylinder above the piston, and the foot pedal is connected to the bottom of the piston and extends out of the negative pressure cylinder.

[0017] According to the solution, when the foot pedal is stepped down, the piston is driven to move downward, and the air in the suction cup is sucked away through the negative pressure tube, so that the suction cup is adsorbed and fixed.

[0018] Preferably, a return spring is provided in the negative pressure cylinder, and the return spring is located at the bottom of the foot pedal and always applies an upward thrust to the foot pedal.

[0019] With this solution, when the foot pedal is released from fixation, the return spring can push the foot pedal to move upward and return to its original position, without the need for manual return, thereby improving the reliability of use.

[0020] Preferably, a vertical groove arranged vertically is provided at the lower half of the negative pressure cylinder, a fixing groove is provided at one side of the bottom of the vertical groove, and the foot pedal extends out of the negative pressure cylinder through the vertical groove.

[0021] According to the solution, after the foot pedal moves downward along the vertical groove, it is rotated to one side to fix the foot pedal, thereby ensuring the suction force of the suction cup.

[0022] One of the technical effects of the utility model is that the glass plate transfer rack can realize the inclined transportation of the glass plate, avoid occupying a large space, and facilitate transportation; the bracket at the bottom of the glass plate can support the weight of the glass plate, avoid causing a large burden on the suction cup, thereby reducing the possibility of falling caused by bumps and improving the reliability of the glass plate during transportation.
