Description

[0002] A substrate, as one of the core components of electronic products, usually refers to a flat material that bears structures such as circuits, components, or display layers, such as glass substrates, metal substrates, or flexible substrates. The main function of a laminating machine is to accurately attach protective films, functional films, etc. on the surfaces of various substrates to protect the substrate surfaces from scratches and contamination or to achieve specific functions. During the laminating process, a suction tray is used to suck the substrate from the feeding area and smoothly transfer it to the laminating station.

[0003] However, during the process of transferring the substrate by the existing suction tray of the laminating machine, the adsorption of the suction cup on the substrate is not sufficient. Especially when transferring at high speed or when the substrate material and size change, the substrate is prone to detachment, resulting in material loss, increasing production costs, and may also affect the normal operation of the entire production line due to substrate damage, reducing production efficiency, and increasing the burden on operators. Therefore, a device for preventing substrate detachment on the suction tray of a laminating machine is proposed. Summary of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Refer to Figures 1 - 6, an embodiment provided by the present utility model: a device for preventing the substrate from falling off the suction tray of a film laminating machine, comprising a chassis 1 and a connecting rod 2. The bottom of the connecting rod 2 is fixedly connected to a suction tray body 3. A first motor 4 is fixedly installed inside the connecting rod 2. The output end of the first motor 4 is fixedly connected to a driving gear 5. A driven gear 6 is meshed with the driving gear 5. A driving bevel gear 7 is fixedly connected to the driven gear 6. A driven bevel gear 8 is meshed with the driving bevel gear 7. A clamping threaded rod 9 is fixedly connected to the driven bevel gear 8. A clamping threaded block 10 is threadedly connected to the clamping threaded rod 9. A chute 11 is provided on the suction tray body 3. The clamping threaded block 10 is slidably connected in the chute 11. A sliding rod 12 is slidably connected to the clamping threaded block 10. One end of the sliding rod 12 is fixedly connected to a limiting plate 13. The other end of the sliding rod 12 is fixedly connected to a clamping plate 14. A spring 15 is sleeved on the sliding rod 12. The two ends of the spring 15 are respectively fixedly connected to the clamping plate 14 and the clamping threaded block 10. A vacuum suction cup 16 is provided at the bottom of the suction tray body 3. The vacuum suction cup 16 belongs to the prior art for those skilled in the art, and its working principle and circuit structure are known and disclosed, so no further elaboration will be made. When in use, the first motor 4 is started. The first motor 4 drives the four groups of driven gears 6 to rotate through the driving gear 5, so that the driven gears 6 drive the driven bevel gears 8 and the clamping threaded rods 9 to rotate through the driving bevel gears 7, so that the clamping threaded rods 9 drive the clamping threaded blocks 10 to move along the chute 11. Since the four groups of driven gears 6 are all meshed with the driving gear 5, the four groups of clamping threaded blocks 10 approach the center of the substrate. During this process, when the clamping plate 14 contacts the edge of the substrate, the spring 15 is squeezed by the width of the substrate itself. At this time, the sliding rod 12 will slide on the clamping threaded block 10. Due to the interaction of forces, the clamping plate 14 will be driven to reset under the elastic force of the spring 15. The four sides of the substrate are firmly clamped by using the clamping plate 14. At the same time, combined with the adsorption effect of the vacuum suction cup 16, the accidental falling off of the substrate during transportation is effectively prevented, the stability and safety of production are improved, and the production loss caused by the falling off of the substrate is reduced.

[0031] In addition, a second motor 17 is fixedly installed on the chassis 1. The output end of the second motor 17 is fixedly connected to a driving bevel gear 18. A follower bevel gear 19 is meshed with the driving bevel gear 18. A horizontal threaded rod 20 is fixedly connected to the follower bevel gear 19. An installation block 21 is threadedly connected to the horizontal threaded rod 20. A fixing plate 22 is fixedly connected to the chassis 1. A limiting groove 23 is formed in the fixing plate 22. The installation block 21 is slidably connected in the limiting groove 23. When the second motor 17 is started, the second motor 17 drives the follower bevel gear 19 to rotate through the driving bevel gear 18, so that the follower bevel gear 19 drives the installation block 21 to move smoothly along the limiting groove 23 through the horizontal threaded rod 20, thereby driving the substrate to be horizontally transported. The substrate can be moved to the next processing station for the next step of processing, meeting the requirements of continuous operation of the production line. A third motor 24 is fixedly installed in the installation block 21. The output end of the third motor 24 is fixedly connected to a worm 25. A worm gear 26 is meshed with the worm 25. A lifting gear 27 is fixedly connected to the worm gear 26. A lifting rack 28 is meshed with the lifting gear 27. The lifting rack 28 is fixedly connected to the connecting rod 2. Four groups of driven gears 6 are provided and are all meshed with the driving gear 5. The driving gear 5 and the driven gears 6 all rotate inside the suction cup body 3. Four groups of driving bevel gears 7 and driven bevel gears 8 are provided and are located below the driven gears 6. Four groups of clamping threaded rods 9 and clamping threaded blocks 10 are provided and are evenly distributed on the suction cup body 3. The clamping threaded rods 9 rotate on the suction cup body 3. A plurality of slide rods 12 and springs 15 are provided and are evenly distributed on the clamping threaded blocks 10. Anti-slip pads are provided on the clamping plates 14. A plurality of vacuum suction cups 16 are provided and are evenly distributed at the bottom of the suction cup body 3. The follower bevel gear 19 and the horizontal threaded rod 20 both rotate on the chassis 1. The worm gear 26 and the lifting gear 27 both rotate inside the installation block 21. The connecting rod 2 passes through and slides on the installation block 21. When the third motor 24 is started, the third motor 24 drives the worm gear 26 to rotate through the worm 25, so that the worm gear 26 drives the lifting gear 27 to rotate. The lifting gear 27 drives the connecting rod 2 to move downward through the lifting rack 28, thereby realizing the lifting movement of the suction cup, making the suction cup body 3 approach the substrate, facilitating the substrate to be adsorbed by the vacuum suction cups 16, and improving the production efficiency.

[0032] Working principle: When using the device for preventing the substrate from falling off the suction tray of the laminating machine, the operator places the substrate below the suction tray body 3, and then starts the third motor 24. The third motor 24 drives the worm gear 26 to rotate through the worm 25, so that the worm gear 26 drives the lifting gear 27 to rotate. The lifting gear 27 drives the connecting rod 2 to move downward through the lifting rack 28, making the suction tray body 3 approach the substrate. Then, the substrate is adsorbed by the vacuum suction cup 16. At the same time, the first motor 4 can be started. The first motor 4 drives four groups of driven gears 6 to rotate through the driving gear 5, so that the driven gears 6 drive the driven bevel gears 8 and the clamping threaded rod 9 to rotate through the driving bevel gears 7, making the clamping threaded rod 9 drive the clamping threaded block 10 to move along the chute 11. Since the four groups of driven gears 6 are all meshed with the driving gear 5, the four groups of clamping threaded blocks 10 approach the center of the substrate. When the clamping plates 14 on the clamping threaded blocks 10 contact the four sides of the substrate, due to the width of the substrate itself, the substrate will basically squeeze the spring 15 through the clamping plates 14. At this time, the sliding rod 12 will slide on the clamping threaded block 10. Due to the interaction of forces, the clamping plates 14 will be driven to reset under the elastic force of the spring 15, so as to clamp the four sides of the substrate by the clamping plates 14. By using the adsorption effect of the vacuum suction cup 16 and the clamping effect of the clamping plates 14, the substrate is effectively prevented from falling off the suction tray body 3. Through the setting of the rubber pads on the clamping plates 14, the substrate is prevented from being scratched and damaged. After the substrate is adsorbed, the output end of the third motor 24 can be rotated in the reverse direction, so as to drive the suction tray body 3 and the substrate to move upward. Then, the second motor 17 is started. The second motor 17 drives the follower bevel gear 19 to rotate through the driving bevel gear 18, so that the follower bevel gear 19 drives the mounting block 21 to move along the limiting groove 23 through the transverse threaded rod 20, thereby realizing the transfer operation of the substrate, and the substrate can be moved to the next processing station for the next step of processing.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
