[0002] Automatic transmission equipment is widely used in the production process of LCD screens. Automatic transmission equipment uses automation technology to liberate people from heavy physical labor, some mental labor, and harsh and dangerous working environments.

[0003] When the automatic transmission equipment transports the LCD screen, the side guard guide wheel is needed. The existing side guard guide wheel has many problems or defects. In actual use, the traditional side guard guide wheel is easy to loosen or fall off. When the guide wheel at a certain position in a conveyor line becomes loose or falls off, if it is not replaced in time, it will hinder the normal transportation of the LCD screen products. Since the conveying interval requirements in the automatic production line are relatively high, the LCD screen products cannot be transported to the next production process within the specified time interval after being blocked, which will affect the smooth transportation of the process. At the same time, the blocked products may also affect the subsequent conveyed products, reducing the conveying efficiency of the production line, and there are certain defects.

[0004] Therefore, we proposed a stable UPE guide wheel for LCD production line to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a stable UPE guide wheel for a liquid crystal display production line to solve the problem that when a guide wheel at a certain position in the conveyor line becomes loose or falls off, if it is not replaced in time, it will hinder the normal conveying of the liquid crystal display products and may also affect the subsequent conveyed products, thereby reducing the conveying efficiency of the production line.

[0015] By adopting the above technical scheme, a clamping assembly is provided. When installing the guide wheel body, the installation sleeve is put on the outside of the rotating shaft, pressing the guide wheel body. When the installation sleeve moves, it will squeeze the sliding rod, and the rotating rod will rotate and compress the spring. When the positioning block slides to the position of the blocking groove, the guide wheel body is released, the positioning block is stuck in the blocking groove, and the rotation of the rotating rod will drive the blocking block to be stuck in the blocking groove.

[0025] By adopting the above technical solution, the resistance block will compress the spring four, and the rubber blocks at both ends of the spring four will play a further role in absorbing and buffering, thereby reducing the collision stress on the guide wheel body.

[0026] Preferably, one end of the spring four away from the adapter block is fixedly connected to the stop block, and the stop block is located between the two connecting rods.

[0027] By adopting the above technical solution, the connecting rods are symmetrically arranged, thereby improving the buffer protection effect.

[0030] Compared with the prior art, the invention has the following beneficial effects: a clamping assembly is provided, and when installing the guide wheel body, the installation sleeve is sleeved on the outer side of the rotating shaft to press the guide wheel body, and the installation sleeve will squeeze the sliding rod when it moves, and the rotating rod will rotate and compress the spring 1, and when the positioning block slides to the position of the blocking groove, the guide wheel body is released, the positioning block is stuck in the blocking groove, and the rotation of the rotating rod will drive the clamping block to be stuck in the clamping groove, and the clamping and fixing of the clamping block and the positioning block improve the installation stability of the guide wheel body, reduce the loosening or falling off of the guide wheel body, and also facilitate the replacement of a new guide wheel body for use;

[0031] 1. A clamping assembly is provided. When installing the guide wheel body, the guide wheel body is fixed to the mounting sleeve by bolts to facilitate the installation of guide wheel bodies of different sizes. Then the mounting sleeve is sleeved on the outside of the rotating shaft so that the positioning block inside the mounting sleeve corresponds to the position of the vertical slot. The guide wheel body is pressed so that the mounting sleeve slides on the rotating shaft. When the mounting sleeve moves, it squeezes the slide bar, and the slide bar drives the push block to move and stretches the second spring. The push block squeezes the rotating rod. When the positioning block slides to the position of the blocking slot, the position of the card block corresponds to the position of the card slot. At this time, the guide wheel body is released, and the elastic force of the second spring drives the slide bar to reset and move a certain distance until the positioning block is stuck in the blocking slot. The rotation of the movable rod will drive the card block to be stuck in the card slot. The card block and the positioning block are fixed by the card connection, which improves the installation stability of the guide wheel body and reduces the loosening or falling off of the guide wheel body. Similarly, when the damaged or loose guide wheel body needs to be replaced, the guide wheel body is pushed to make the positioning block fall out of the blocking groove, and then the guide wheel body is reversed to facilitate the replacement of the new guide wheel body. This solves the problem that when the guide wheel at a certain position in the conveyor line is loose or falls off, if it is not replaced in time, it will hinder the normal transportation of the LCD product, and may also affect the subsequent conveyed products, thereby reducing the conveying efficiency of the production line.

[0032] 2. A protection component is provided. One end of the protection plate is arc-shaped. The protection plate is close to the guide wheel body. When the conveyor belt is running to transport LCD display products, the products may collide with the guide wheel body. At this time, the guide wheel body will squeeze the protection plate, and the protection plate will shrink toward the inside of the side groove. The protection plate squeezes the connecting rod and the stop block, so that the connecting rod is unfolded, and the connecting rod drives the slider to slide on the vertical rod. The slider compresses spring three. A rubber block is installed at the end of spring three for absorbing and buffering, which can play a preliminary buffering role. At the same time, the stop block compresses spring four. The rubber blocks at both ends of spring four play a further role in absorbing and buffering, thereby reducing the collision stress on the guide wheel body, reducing the loosening or falling off of the guide wheel body, and extending the service life of the guide wheel body.

[0056] Embodiment 1: Figure 1-9 As shown, a clamping assembly 4 is provided. When installing the guide wheel body 44, the guide wheel body 44 is fixed to the mounting sleeve 43 by bolts to facilitate the installation of guide wheel bodies 44 of different sizes. Then the mounting sleeve 43 is sleeved on the outer side of the rotating shaft 42, so that the positioning block 416 inside the mounting sleeve 43 corresponds to the position of the vertical groove 417. The guide wheel body 44 is pressed to make the mounting sleeve 43 slide on the rotating shaft 42. When the mounting sleeve 43 moves, it squeezes the sliding rod 46. The sliding rod 46 drives the pushing block 47 to move and stretch the spring 2 415. The pushing block 47 squeezes the rotating rod 411, so that the rotating rod 411 rotates and compresses the spring 1 412.

[0057] Until the positioning block 416 slides to the position of the adjustment groove 418, the guide wheel body 44 is rotated, and the guide wheel body 44 drives the installation sleeve 43 to rotate. When the positioning block 416 slides to the position of the blocking groove 419, the block 414 corresponds to the position of the slot 413. At this time, the guide wheel body 44 is released, and the elastic force of the spring 2 415 drives the slide rod 46 to reset and move a distance until the positioning block 416 is stuck in the blocking groove 419.

The clamping and fixing of the block 414 and the positioning block 416 improves the installation stability of the guide wheel body 44 and reduces the loosening or falling off of the guide wheel body 44.

[0058] Similarly, when it is necessary to replace the damaged or loose guide wheel body 44, push the guide wheel body 44 to make the positioning block 416 disengage from the blocking groove 419, and then reverse the guide wheel body 44 to make the positioning block 416 slide into the vertical groove 417.

This solves the problem that when the guide wheel at a certain position in the conveyor line becomes loose or falls off, if it is not replaced in time, it will hinder the normal transportation of the LCD display products, and may also affect the subsequent products transported, thereby reducing the transportation efficiency of the production line.

[0059] The protection assembly 5 includes a side groove 51 and a vertical rod 52. The side groove 51 is opened inside the two sides of the frame 1. The vertical rod 52 is slidably connected to the side groove 51. The outer side of the vertical rod 52 is slidably connected with a slider 53. The outer side of the vertical rod 52 is sleeved with a spring 54. The side of the side groove 51 close to the guide wheel body 44 is slidably connected with a protection plate 56. The side of the protection plate 56 close to the vertical rod 52 is symmetrically rotatably connected with a connecting rod 55.

[0060] The slider 53 is symmetrically arranged in the upper and lower parts. The end of the connecting rod 55 away from the protective plate 56 is rotatably connected to the slider 53. An adapter block 57 is fixedly connected to the middle of the side of the vertical rod 52 close to the protective plate 56. A spring four 58 is fixedly connected to one side of the adapter block 57. A stop block 59 is fixedly connected to the middle of the side of the protective plate 56 close to the adapter block 57.

[0061] One end of the spring four 58 away from the adapter block 57 is fixedly connected to the stop block 59, and the stop block 59 is located between the two connecting rods 55.

[0062] Spring three 54 is located on the side of the slider 53 away from the adapter block 57, one end of the spring three 54 is fixedly connected to the frame 1, the other end of the spring three 54 is fixedly connected to the slider 53, and the vertical rod 52 is slidably connected to the spring three 54.

[0063] Embodiment 2: Figure 10-11As shown, a protection component 5 is provided, one end of the protection plate 56 is arranged in an arc shape, and the protection plate 56 is close to the guide wheel body 44. When the conveyor belt 6 is running to transport the liquid crystal display product, the product may collide with the guide wheel body 44. At this time, the guide wheel body 44 will squeeze the protection plate 56, and the protection plate 56 will shrink toward the inside of the side groove 51. The protection plate 56 squeezes the connecting rod 55 and the stop block 59, so that the connecting rod 55 is unfolded, and the connecting rod 55 drives the slider 53 to slide on the vertical rod 52. The slider 53 compresses the spring three 54. The end of the spring three 54 is installed with a rubber block for absorbing and buffering, which can play a preliminary buffering role. At the same time, the stop block 59 will compress the spring four 58. The rubber blocks at both ends of the spring four 58 play a role of further absorbing and buffering, thereby reducing the collision stress on the guide wheel body 44, reducing the loosening or falling off of the guide wheel body 44, and extending the service life of the guide wheel body 44.

[0064] Working principle: When using the device, first, Figure 1-11 As shown, when installing the guide wheel body 44, the guide wheel body 44 is fixed to the mounting sleeve 43 by bolts to facilitate the installation of guide wheel bodies 44 of different sizes, and then the mounting sleeve 43 is sleeved on the outer side of the rotating shaft 42, so that the positioning block 416 inside the mounting sleeve 43 corresponds to the position of the vertical groove 417, and the guide wheel body 44 is pressed to make the mounting sleeve 43 slide on the rotating shaft 42. When the mounting sleeve 43 moves, it will squeeze the sliding rod 46, and the sliding rod 46 drives the pushing block 47 to move and stretch the spring 2 415, and the pushing block 47 squeezes the rotating rod 411, so that the rotating rod 411 rotates and compresses the spring 1 412.

[0065] When the positioning block 416 slides to the position of the adjustment groove 418, the guide wheel body 44 is rotated, and the guide wheel body 44 drives the installation sleeve 43 to rotate. When the positioning block 416 slides to the position of the blocking groove 419, the blocking block 414 corresponds to the position of the blocking groove 413. At this time, the guide wheel body 44 is released, and the elastic force of the spring 2 415 drives the sliding rod 46 to reset and move a distance until the positioning block 416 is stuck in the blocking groove 419. The rotation of the rotating rod 411 will drive the blocking block 414 to be stuck in the blocking groove 413. The blocking and fixing of the blocking block 414 and the positioning block 416 improves the installation stability of the guide wheel body 44 and reduces the loosening or falling off of the guide wheel body 44.

[0066] When the damaged or loose guide wheel body 44 needs to be replaced, the guide wheel body 44 is pushed to make the positioning block 416 disengage from the blocking groove 419, and then the guide wheel body 44 is reversed to make the positioning block 416 slide into the vertical groove 417. At this time, the elastic force of the spring 2 415 drives the disc 45 and the mounting sleeve 43 to move, so that the mounting sleeve 43 pops out, which is convenient for replacing the new guide wheel body 44 for use.

[0067] When the conveyor belt 6 is running to transport LCD display products, the products may collide with the guide wheel body 44. At this time, the guide wheel body 44 will squeeze the protection plate 56, and the protection plate 56 will shrink toward the inside of the side groove 51. The protection plate 56 squeezes the connecting rod 55 and the stop block 59, so that the connecting rod 55 is unfolded, and the connecting rod 55 drives the slider 53 to slide on the vertical rod 52. The slider 53 compresses the spring three 54. The end of the spring three 54 is equipped with a rubber block for absorbing and buffering, which can play a preliminary buffering role. At the same time, the stop block 59 will compress the spring four 58. The rubber blocks at both ends of the spring four 58 play a further role in absorbing and buffering, thereby reducing the collision stress on the guide wheel body 44, reducing the loosening or falling off of the guide wheel body 44, and extending the service life of the guide wheel body 44.
