Description

Technical Field

[0001] This utility model belongs to the field of glass production technology and relates to a transfer device for processing display glass sheets. Background Technology

[0002] Glass is a hard and brittle transparent material without a definite melting point. It is usually made by mixing raw materials such as quartz sand, limestone, and soda ash, melting them at high temperature, shaping them, and then cooling them. Display glass is a type of glass. A transfer device for processing display glass is a piece of equipment used to transfer the processed display glass to a predetermined production location.

[0003] As disclosed in patent (CN222554973U), a glass plate transfer device includes a trolley; a fixing plate is fixedly connected to the top of the trolley; a plurality of first damping springs are fixedly connected to the top of the fixing plate; a transfer box is fixedly connected to the end of the first damping springs; a box door is hinged to the side wall of the transfer box; a plurality of transfer frames are fixedly connected to the inner side wall of the transfer box; a connecting assembly is installed at the bottom of the trolley; and casters are fixedly connected to the bottom of the connecting assembly. Through the above structure, the transfer box and the plurality of transfer frames can separate the glass plates during the transfer, reducing scratches and abrasions caused by friction between the glass plates during the movement. At the same time, the first damping springs connect the trolley and the transfer box, which can buffer and reduce vibration of the entire transfer box during the movement, thereby improving the positional stability of the transfer box and the glass plates during the transfer.

[0004] When using the above technology, the following technical problems were found in the prior art: When transporting large pieces of glass, the above device only fixes the four corners of the glass through edge grooves and fixing structures, and there is no physical support for the middle area of ​​the large glass. During transportation, the glass sags due to its own weight, forming a "cantilever beam" structure, which causes periodic vibration displacement in the central area, resulting in internal stress concentration. When the local stress exceeds the bending strength of the glass, it is easy for the glass to break during transportation. Therefore, we have made improvements to this and proposed a transfer device for processing display glass sheets. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a transfer device for processing display glass sheets.

[0006] The present invention discloses a transfer device for processing display glass sheets, comprising a transfer box housing, wherein three glass fixing components are installed inside the transfer box housing, each glass fixing component including a fixed support frame, a support rod installed in the middle of the fixed support frame, a support block 1 installed at the bottom of the support rod, a bidirectional lead screw rotatably connected to the support block 1, and the support block 1 being located in the middle of the bidirectional lead screw, two drive blocks symmetrically threaded onto the bidirectional lead screw, an adjusting rod installed on the drive block, four vacuum suction cups arranged in an array on the adjusting rod, and support blocks 2 rotatably connected to both ends of the bidirectional lead screw, the support blocks 2 being connected to the fixed support frame, one of the support blocks 2 being provided with a drive component, and clamping components being provided at both ends of the fixed support frame.

[0007] The clamping assembly includes a connecting bracket, on which two sets of pneumatic telescopic rods are mounted. Each set of pneumatic telescopic rods has three rods, and the bottom of each set of pneumatic telescopic rods is connected to the same fixing plate. The bottom of the fixing plate is equipped with an anti-slip pad.

[0008] Two support slide rods are symmetrically installed on the fixed support frame, and the two ends of the adjusting rod are slidably connected to the support slide rods. Two sliding blocks are symmetrically installed at the bottom of the adjusting rod, and sliding guide rods are slidably connected to the sliding blocks. The two ends of the four sliding guide rods are respectively connected to the fixed support frame and the support rods.

[0009] The drive assembly includes a mounting box connected to a support block two. A servo motor is installed inside the mounting box, and a worm gear is mounted on the output shaft of the servo motor. The worm gear is rotatably connected inside the mounting box, and a worm wheel is meshed with one side of the worm gear. The worm wheel is connected to one end of a bidirectional lead screw that passes through a support block three.

[0010] The support rod has multiple rotating slots arranged in an array, and sliding rollers are rotatably connected in the rotating slots. Two cushioning pads are symmetrically installed on the fixed support frame.

[0011] The bottom of the transfer box is equipped with four load-bearing casters, two doors are symmetrically installed on one side of the transfer box, and a directional rod is installed at one end of the transfer box.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the adjusting rod on the glass fixing component can support the weight of the glass adsorbed by the suction cup. Especially when encountering large glass, the position of the adjusting rod can be adjusted so that the vacuum suction cup is adsorbed in the middle of the glass, effectively supporting the middle of the glass and preventing the glass from sagging due to its own weight and forming a "cantilever beam" structure, thereby enhancing the stability of the glass during transportation.

[0013] This invention employs a dual fixing method using a vacuum suction cup and a clamping assembly. The vacuum suction cup adsorbs the glass surface through negative pressure, while the pneumatic telescopic rod presses down synchronously, causing the fixing plate to contact the edge of the glass. The anti-slip soft pad adheres to the glass and applies a uniform clamping force. This dual fixing method greatly improves the reliability of glass fixing and effectively solves the problem that large-size glass, due to the lack of physical support in the middle area during transportation, causes periodic vibration displacement in the central area, leading to internal stress concentration and ultimately breakage because the local stress exceeds the glass's bending strength. This reduces the risk of glass breakage during transportation and improves transportation safety and success rate. Attached Figure Description

Detailed Implementation

[0021] 0016 Example

[0022] like Figures 1-6As shown, a transfer device for processing display glass sheets includes a transfer box 1. Three glass fixing assemblies are installed inside the transfer box 1. Each glass fixing assembly includes a fixing support frame 2, a support rod 3 installed in the middle of the fixing support frame 2, a support block 4 installed at the bottom of the support rod 3, a bidirectional lead screw 5 rotatably connected to the support block 4, and the support block 4 being located in the middle of the bidirectional lead screw 5. Two drive blocks 6 are symmetrically threaded onto the bidirectional lead screw 5, an adjusting rod 7 is installed on the drive block 6, and four vacuum suction cups 8 are arranged in an array on the adjusting rod 7. The bidirectional lead screw 5... Both ends of the glass are rotatably connected to support blocks 2 9, which are connected to the fixed support frame 2. One of the support blocks 2 9 is equipped with a drive assembly. Both ends of the fixed support frame 2 are equipped with clamping assemblies, which include connecting brackets 13. Two sets of pneumatic telescopic rods 14 are installed on the connecting brackets 13. Each set of pneumatic telescopic rods 14 has three rods, and the bottom of each set of pneumatic telescopic rods 14 is connected to the same fixed plate 15. The bottom of the fixed plate 15 is equipped with an anti-slip soft pad 16. The anti-slip soft pad 16 is made of silicone with a micro-textured surface design to prevent the glass from slipping on the fixed plate. When sliding occurs, the three pneumatic telescopic rods 14 in each group move synchronously, driving the fixed plate 15 to press down, cooperating with the vacuum suction cup 8 to fix the glass. Two support slide rods 12 are symmetrically installed on the fixed support frame 2, and the two ends of the adjusting rod 7 are slidably connected to the support slide rods 12. Two sliding blocks 10 are symmetrically installed at the bottom of the adjusting rod 7, and sliding guide rods 11 are slidably connected to the sliding blocks 10. The two ends of the four sliding guide rods 11 are respectively connected to the fixed support frame 2 and the support rod 3. The driving assembly includes a mounting box 17, which is connected to the second support block 9. A servo motor 18 is installed inside the mounting box 17. A worm gear 19 is mounted on the output shaft of the servo motor 18. The worm gear 19 is rotatably connected inside the mounting box 17. A worm wheel 20 is meshed with one side of the worm gear 19. The worm wheel 20 is connected to one end of the bidirectional lead screw 5 through the support block 3. The vacuum equipment can be installed on the top of the transfer box 1. The servo motor 18 drives the worm gear 19, worm wheel 20, bidirectional lead screw 5 and other components, so that the drive block 6 drives the adjusting rod 7 to move, thereby adjusting the spacing of the vacuum suction cup 8. It can adapt to glass sheets of different sizes and meet diverse glass transportation needs.

[0023] During operation, the servo motor 18 on the drive assembly drives the worm gear 19 to rotate, which in turn drives the worm wheel 20 connected to it to rotate. Through the transmission of the worm wheel 20, the bidirectional lead screw 5 connected to it is driven to rotate. When the bidirectional lead screw 5 rotates, the symmetrical thread drives the two drive blocks 6 to move in opposite directions along the lead screw axis. When moving, it pushes the adjusting rod 7 to move horizontally, adjusting the spacing of the vacuum suction cups 8 to adapt to glass sheets of different sizes. The sliding block 10 and the sliding guide rod 11 constrain the movement trajectory to ensure that the adjusting rod 7 remains horizontal and stable when moving. The support slide rod 12 is used to support the weight of the glass adsorbed by the suction cups. (When encountering larger glass, the position between the adjusting rods 7 is adjusted so that the vacuum suction cups 8 are adsorbed in the middle of the glass to support the middle of the glass.) After the support distance between the adjusting rods 7 is adjusted, the glass is inserted under the fixing plate 15 on the clamping assembly. Then, the vacuum suction cups 8, which are arranged in an array on the adjusting rods 7, adsorb the glass surface through negative pressure. After that, the glass is pneumatically extended. The retracting rod 14 presses down synchronously, causing the fixing plate 15 to contact the edge of the glass. The anti-slip pad 16 adheres to the glass, applying a uniform clamping force. The vacuum suction cup 8 and the clamping assembly form a double fixation, which enables the glass to be fixed at both ends and supported in the middle when transporting large pieces of glass. The double fixation method greatly improves the reliability of glass fixation and effectively solves the problem that large-sized glass will experience periodic vibration and displacement in the central area during transportation due to the lack of physical support in the middle area, leading to internal stress concentration and eventual breakage due to local stress exceeding the glass's bending strength. This reduces the risk of glass breakage during transportation and improves the safety and success rate of transportation. The adjusting rod 7 on the glass fixing assembly can support the weight of the glass held by the suction cup. Especially when encountering large pieces of glass, the position of the adjusting rod 7 can be adjusted so that the vacuum suction cup 8 is attached to the middle of the glass, providing effective support for the middle of the glass and preventing the glass from sagging due to its own weight and forming a "cantilever beam" structure, thus enhancing the stability of the glass during transportation.

[0024] like Figures 1-4As shown, the support rod 3 has multiple rotating grooves 21 arranged in an array, and sliding rollers 22 are rotatably connected within the rotating grooves 21. Two buffer pads 23 are symmetrically installed on the fixed support frame 2. During operation, when inserting the glass into the clamping assembly, the direct contact between the glass and the support rod 3 generates significant friction, requiring considerable effort from the operator to push the glass. The sliding rollers 22 within the array of rotating grooves 21 transform the sliding friction between the glass and the support rod 3 into rolling friction, greatly reducing friction and allowing the operator to insert the glass into the designated position more easily and conveniently, improving work efficiency and reducing manpower consumption. During glass transportation, various external forces are inevitably applied, such as road bumps, vehicle starting and braking, etc., causing the glass to vibrate. The buffer pads 23 symmetrically installed on the fixed support frame 2 act as buffers and shock absorbers between the glass and the fixed support frame 2, absorbing and dispersing vibration energy, effectively reducing the amplitude and frequency of glass vibration, keeping the glass relatively stable during transportation, and reducing the risk of displacement, collision, or even damage due to vibration.

[0025] The bottom of the transfer box 1 is equipped with four load-bearing casters 25. Two doors 24 are symmetrically installed on one side of the transfer box 1, and a directional rod 26 is installed at one end of the transfer box 1. The directional rod 26 and the four load-bearing casters 25 enable the transfer box 1 to move freely in all directions. Operators can easily push the box to the designated position according to actual needs, which is convenient for transferring glass. The doors 24 can play a sealing and protective role during transportation, preventing external dust, debris and other objects from entering the box and contaminating or damaging the glass surface.

[0026] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
