Description

Technical Field

[0001] The present invention relates to the technical field of anti-fragmentation films for liquid crystal screens, and in particular to an anti-fragmentation film device. Background Art

[0002] With the development of technology, LCD screens are becoming thinner and lighter. In the production process of LCD screens, a conveying device is needed to transport the LCD screens to the next process. Since the LCD screens are thin and small in size, they are light in weight and are easily affected by external forces such as water, wind and brushes during transportation, causing them to be skewed, making it inconvenient for the grasping device to grasp them. Therefore, a clapper positioning device is usually required to reset the skewed LCD screen on the conveying device to facilitate the grasping device to grasp it. However, the clapper positioning device needs to directly contact the two sides of the LCD screen during the resetting of the LCD screen. If the force of the clapper positioning device is too large, it is easy to cause the edges or corners of the LCD screen to break, resulting in the LCD screen being scrapped. Summary of the invention

[0003] In view of this, the present invention provides an anti-fragmentation device to solve the problem that the edge or corner of the LCD screen may be easily broken due to the excessive force of the clapper positioning device, resulting in the LCD screen being scrapped.

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0036] After the surface of the product 22 is cleaned, when it is transported to the next process through the conveying device 1, it is necessary to use an air knife to remove the residual water on the upper and lower surfaces of the product 22. The upper air knife is arranged above the conveying device 1, and can remove the residual water on the upper end surface of the product 22. Because the lower air knife needs to be installed to remove the residual water on the lower end surface of the product 22, and the roller will hinder the lower air knife, it is necessary to intercept the roller and reserve a position for installing the lower air knife. As a result, when the product 22 moves to the lower air knife, there is a lack of support from the bottom roller, which is prone to fragmentation. At the same time, when the air knife blows air on the surface of the product 22, it is easy to blow up the product 22, resulting in the risk of fragmentation.

[0037] Combine the following Figures 1 to 5 , describing an embodiment of the present invention.

[0038] According to an embodiment of the present invention, there is provided an anti-fragmentation device, comprising: a clapper positioning assembly.

[0039] Specifically, the clapperboard positioning component is arranged at the bottom of the conveying device 1, and the clapperboard positioning component includes a first clapperboard bracket 2 and a second clapperboard bracket 3. The second clapperboard bracket 3 is fixedly arranged on one side of the conveying device 1, and the first clapperboard bracket 2 is movably arranged on the other side of the conveying device 1 to move toward or away from the second clapperboard bracket 3. A push plate 4 is movably arranged on the first clapperboard bracket 2, and the push plate 4 has a state of being forced to move away from the second clapperboard bracket 3. An elastic buffer 5 connected to the push plate 4 is arranged on the first clapperboard bracket 2 to provide a support for the push plate 4. To provide an elastic holding force to maintain the initial state, a plurality of push rods 6 are respectively provided on the push plate 4 and the second beater bracket 3, one end of the push rod 6 is fixedly connected to the push plate 4 or the second beater bracket 3, and the other end of the push rod 6 extends out of the conveying device 1. The push rods 6 on both sides are arranged opposite to each other. The conveying device 1 includes a plurality of rollers arranged at intervals, and the product 22 is moved by the rollers. The push rods 6 are arranged between adjacent rollers and are perpendicular to the rollers. The first beater bracket 2 is suitable for moving in a direction close to the second beater bracket 3 so that the extended end of the push rod 6 abuts against the product 22 to drive the product 22 to reset.

[0040] In this embodiment, the clapper positioning assembly is arranged at the bottom of the conveying device 1 and at the matching position of the conveying device 1 and the grabbing device. The clapper positioning assembly can straighten and reset the product 22 on the conveying device 1 to facilitate the grabbing device to grab the product 22. The conveying device 1 includes a plurality of rollers, adjacent rollers are arranged at intervals, the product 22 is placed on the rollers, and the rollers rotate to drive the product 22 to move. The clapper positioning assembly includes a first clapper bracket 2 and a second clapper bracket 3, the first clapper bracket 2 and the second clapper bracket 3 are respectively arranged on both sides of the conveying device 1, and the first clapper bracket 2 and the second clapper bracket 3 are parallel to the moving direction of the product 22, the second clapper bracket 3 is fixedly arranged on one side of the conveying device 1, and the first clapper bracket 2 is movably arranged on the other side of the conveying device 1, the first clapper bracket 2 can move toward the second clapper bracket 3, so as to abut against the product 22 on the conveying device 1, and drive the product 22 on the conveying device 1 to rotate and reset, after the product 22 is reset, the first clapper bracket 2 can move in a direction away from the second clapper bracket 3 and reset. A movable push plate 4 is provided on the first clapper bracket 2, and the push plate 4 can move in a direction away from the second clapper bracket 3. An elastic buffer 5 is provided on the first clapper bracket 2, and the elastic buffer 5 is connected to the push plate 4. The elastic buffer 5 can provide an elastic retaining force for the push plate 4 to maintain its initial state. A plurality of push rods 6 are fixedly provided on the push plate 4 and the second clapper bracket 3, respectively. The lower end of the push rod 6 is fixedly connected to the push plate 4 or the second clapper bracket 3, and the upper end of the push rod 6 extends out of the conveying device 1. The push rod 6 is perpendicular to the roller, and the upper end of the push rod 6 is higher than the roller. The push rod 6 is arranged between adjacent rollers. The push rod 6 on the push plate 4 is arranged one-to-one with the push rod 6 on the second clapper bracket 3, and the push rod 6 on the push plate 4 can move with the push plate 4. When it is necessary to position the product 22, the product 22 is located on the conveying device 1 and between the first clapper bracket 2 and the second clapper bracket 3. The first clapper bracket 2 moves toward the second clapper bracket 3, and the push plate 4 moves with the first clapper bracket 2. The push rod 6 on the push plate 4 first contacts with the product 22 and pushes the product 22 so that the other end of the product 22 contacts the push rod 6 on the second clapper bracket 3. At this time, the product 22 is subjected to forces on both sides, and the first clapper bracket 2 continues to move toward the second clapper bracket 3. The push rod 6 on the push plate 4 applies a thrust to the product 22 to drive the product 22 to rotate. At the same time, the push plate 4 will also be subjected to the reaction force of the product 22 and move in the direction away from the second clapper bracket 3, and at the same time, apply a thrust to the elastic buffer 5. Until the product 22 is reset, the first clapper bracket 2 drives the push plate 4 to move in the direction away from the second clapper bracket 3, and the elastic buffer 5 drives the push plate 4 to gradually reset through the elastic force.

[0041] Preferably, the elastic buffer 5 is a spring, one end of the spring is connected to the first clapper bracket 2, and the other end of the spring is connected to the push plate 4.

[0042] It should be noted that, by arranging a movable push plate 4 and an elastic buffer 5 on the first beater bracket 2, the push plate 4 will move away from the second beater bracket 3 after being subjected to force, and at the same time, the elastic buffer will provide thrust for the push plate 4 so that the push plate 4 is always in contact with the product 22 and drives the product 22 to rotate. The push plate 4 can reduce the stress on the product 22 when moving, and prevent the product 22 from being subjected to too much stress, resulting in edge or corner breakage of the product 22.

The blocking structure 7 has a plurality of blocking members 8, and the blocking members 8 abut against the product 22 to limit the product 22. The contact surface between the blocking member 8 and the product 22 is an inclined surface, and the angle between the inclined surface and the product 22 is greater than 90°.

[0044] In this embodiment, the blocking structure 7 is arranged at the front end of the conveying direction of the conveying device 1. The blocking structure 7 can be used to block the product 22. The blocking structure 7 has a plurality of blocking members 8. The blocking members 8 abut against the product 22. The contact surface between the blocking member 8 and the product 22 is an inclined surface. The angle between the inclined surface and the product 22 is greater than 90°, so that the blocking member 8 and the product 22 are in point contact. When the grasping device grasps the product 22, the side of the product 22 will not rub against the blocking member 8.

[0045] Preferably, in this embodiment, the blocking member 8 is a truncated platform structure, and the diameter of the upper end surface of the blocking member 8 is smaller than the diameter of the lower end surface.

[0046] It should be noted that by setting the contact surface between the blocking member 8 and the product 22 as an inclined surface, the angle between the inclined surface and the product 22 is greater than 90°, so that the blocking member 8 and the product 22 are in point contact, and when the product 22 is grasped by the grasping device and rises, there will be no friction or collision with the blocking member 8, which can avoid the friction and collision between the product 22 and the blocking member 8 during the rising process, resulting in the edge or corner of the product 22 being broken.

The pressure wheel assembly 10 includes a rotating shaft and a pressure wheel. The pressure wheel is sleeved and fixed on the rotating shaft. There is a gap between the pressure wheel and the roller for the product 22 to pass through. When the product 22 passes between the pressure wheel and the roller, the pressure wheel and the roller respectively contact the upper and lower end surfaces of the product 22 and provide clamping force to the product 22, so that the product 22 can move stably on the roller. The pressure wheel is a driven wheel. The product 22 drives the pressure wheel to rotate, and the pressure wheel drives the rotating shaft to rotate. The two ends of the rotating shaft are rotatably arranged on the two side walls of the conveying device 1.
