Description

Technical Field

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

[0002] With the development of technology, liquid crystal screens are becoming thinner and lighter. During the production process of liquid crystal screens, a conveying device is required to transport the liquid crystal screens to the next process. Due to the thinness and small size of the liquid crystal screens, their weight is relatively light, and they are prone to being skewed under the action of external forces such as water, wind, and brushes during transportation, making it inconvenient for the grasping device to grasp them. Therefore, a clapper positioning device is usually needed to reset the skewed liquid crystal screens on the conveying device, so as to facilitate the grasping device to grasp them. However, during the process of resetting the liquid crystal screens by the clapper positioning device, it is necessary to directly abut against both sides of the liquid crystal screens. If the acting force of the clapper positioning device is too large, it is easy to cause the edges or corners of the liquid crystal screens to break, resulting in the scrapping of the liquid crystal screens. Summary of the Invention

[0003] In view of this, the present invention provides an anti-fragmentation device to solve the problem that the excessive acting force of the clapper positioning device is easy to cause the edges or corners of the liquid crystal screens to break, resulting in the scrapping of the liquid crystal screens.

[0004] The present invention provides an anti-fragmentation device, including:

[0005] A clapper positioning assembly, arranged at the bottom of the conveying device. The clapper positioning assembly includes a first clapper bracket and a second clapper bracket. The second clapper bracket is fixedly arranged on one side of the conveying device, and the first clapper bracket is movably arranged on the other side of the conveying device to move in a direction approaching or away from the second clapper bracket. A push plate is movably arranged on the first clapper bracket. The push plate has a state of moving away from the second clapper bracket under force. An elastic buffer member connected to the push plate is arranged on the first clapper bracket to provide an elastic holding force for the push plate to maintain its initial state. A plurality of push rods are respectively arranged on the push plate and the second clapper bracket. One end of the push rod is fixedly connected to the push plate or the second clapper bracket, and the other end of the push rod extends out of the conveying device. The push rods on both sides are arranged oppositely. The conveying device includes a plurality of rollers arranged at intervals, and the product moves through the rollers. The push rod is arranged between adjacent rollers and is perpendicular to the rollers. The first clapper bracket is adapted to move in a direction approaching the second clapper bracket, so that the extended ends of the push rods abut against the product to drive the product to be reset.

[0006] Advantageous Effects:

[0007] By providing a movable push plate and an elastic buffer on the first beater bracket, when the push plate is stressed, it will move away from the second beater bracket. At the same time, the elastic buffer will provide a thrust for the push plate to always abut against the product and drive the product to rotate. When the push plate moves, the stress on the product can be reduced, preventing the product from being damaged due to excessive stress, such as edge or corner breakage.

[0008] In an alternative embodiment, the beater positioning assembly further includes a blocking structure disposed at the front end in the conveying direction of the conveying device. The blocking structure has a plurality of blocking members that abut against the product to limit the position of the product. The contact surface of the blocking member with the product is an inclined surface, and the angle between the inclined surface and the product is greater than 90°.

[0009] Beneficial effects:

[0010] By setting the contact surface of the blocking member with the product as an inclined surface with an angle greater than 90° between the inclined surface and the product, the blocking member is in point contact with the product. When the product is grabbed by the grabbing device and lifted, there will be no friction and collision with the blocking member, avoiding the situation where the product edge or corner is broken due to friction and collision with the blocking member during the lifting process.

[0011] In an alternative embodiment, the conveying device has an avoidance position for setting a down air knife. A plurality of transition guide wheels are arranged in the avoidance position, and adjacent transition guide wheels are arranged at intervals. The transition guide wheels are in the same plane as the rollers, and the transition guide wheels are adapted to contact the bottom surface of the product and drive the product to move.

[0012] Beneficial effects:

[0013] By arranging transition guide wheels in the avoidance position, the product is supported by the transition guide wheels when passing through the down air knife, preventing the problem of product breakage due to lack of support.

[0014] In an alternative embodiment, a pressure wheel assembly is provided on the conveying device. The pressure wheel assembly is arranged on both sides of the up air knife. The pressure wheel assembly is parallel to the rollers, and the pressure wheel assembly contacts the upper surface of the product and cooperates with the rollers to limit the position of the product.

[0015] Beneficial effects:

[0016] By providing pressure wheels, the pressure wheels and the rollers can provide a clamping force for the product, preventing the problem that the product is blown by the up and down air knives and separated from the rollers, resulting in broken pieces.

[0017] In an alternative embodiment, a plurality of guide wheels are respectively arranged on both sides of the conveying device, and adjacent guide wheels are arranged at intervals. The guide wheels contact the product to limit the position of the product.

[0018] Beneficial effects:

[0019] The guide wheel can limit the product to prevent the product from shifting during transportation and causing fragmentation.

[0020] In an alternative embodiment, it further includes: a suction cup assembly disposed above the platen positioning assembly and the conveying device. The suction cup assembly includes a first driving structure and suction cups. The first driving structure is connected to the suction cups to drive the suction cups to move towards or away from the conveying device. The suction cups have a first adsorption position, a second adsorption position, and a third adsorption position. The first adsorption position is disposed within the second adsorption position, and the second adsorption position is disposed within the third adsorption position. A plurality of vacuum suction nozzles are provided within the first adsorption position, the second adsorption position, and the third adsorption position. The first adsorption position, the second adsorption position, and the third adsorption position are adapted to adsorb products of different sizes.

[0021] Beneficial effects:

[0022] It is possible to select different adsorption positions according to the size of the product, which improves the practicability and can also prevent the problem that the product falls due to the small adsorption force of the suction cup when the product is too large, resulting in product fragmentation and scrapping.

[0023] In an alternative embodiment, a check structure is provided within the vacuum suction nozzle.

[0024] In an alternative embodiment, the protruding end of the push rod has an abutting member, and the abutting member abuts against the product to drive the product to reset.

[0025] In an alternative embodiment, the platen positioning assembly further includes a lead screw and a second driving structure. The first platen bracket is movably disposed at one end of the lead screw. The second driving structure is connected to the lead screw, and the rotation of the lead screw is adapted to drive the first platen bracket to approach or move away from the second platen bracket.

[0026] In an alternative embodiment, a slider is provided at the bottom of the push plate, and a slide rail is provided on the first platen bracket. The slider is slidably connected to the slide rail so that the push plate is movably disposed on the first platen bracket. Description of the drawings

Detailed implementation manners

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] After the surface of the product 22 is cleaned and transported to the next process by the conveying device 1, an air knife is required 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. Since a 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 obstruct the lower air knife, the roller needs to be cut off to reserve a position for installing the lower air knife. As a result, when the product 22 moves to the position of the lower air knife, there is a lack of support from the bottom roller, which easily causes the problem of chip breakage. At the same time, when the air knife blows air on the surface of the product 22, the product 22 is easily blown up, resulting in the risk of chip breakage.

[0037] The following combines Figures 1 to 5 , to describe the embodiments of the present invention.

[0038] According to an embodiment of the present invention, a fragment-proof device is provided, including: a beater positioning assembly.

[0039] Specifically, the beater positioning assembly is arranged at the bottom of the conveying device 1. The beater positioning assembly includes a first beater bracket 2 and a second beater bracket 3. The second beater bracket 3 is fixedly arranged on one side of the conveying device 1, and the first beater bracket 2 is movably arranged on the other side of the conveying device 1 to move in a direction close to or away from the second beater bracket 3. A push plate 4 is movably arranged on the first beater bracket 2. The push plate 4 has a state of moving away from the second beater bracket 3 under force. An elastic buffer member 5 connected to the push plate 4 is arranged on the first beater bracket 2 to provide an elastic holding force for the push plate 4 to maintain its initial state. A plurality of push rods 6 are respectively arranged 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 oppositely. The conveying device 1 includes a plurality of rollers arranged at intervals. The product 22 moves through the rollers. The push rods 6 are arranged between adjacent rollers and are perpendicular to the rollers. The first beater bracket 2 is adapted to move in a direction close to the second beater bracket 3 so that the extended ends of the push rods 6 abut against the product 22 to drive the product 22 to reset.

[0040] In this embodiment, the beater positioning assembly is arranged at the bottom of the conveying device 1 and is located at the mating position of the conveying device 1 and the grasping device. The beater positioning assembly can square up and reset the product 22 located on the conveying device 1 to facilitate the grasping device to grasp the product 22. The conveying device 1 includes a plurality of rollers, and adjacent rollers are arranged at intervals. The product 22 is placed on the rollers, and the rotation of the rollers drives the product 22 to move. The beater positioning assembly includes a first beater bracket 2 and a second beater bracket 3. The first beater bracket 2 and the second beater bracket 3 are respectively arranged on both sides of the conveying device 1, and the first beater bracket 2 and the second beater bracket 3 are parallel to the moving direction of the product 22. The second beater bracket 3 is fixedly arranged on one side of the conveying device 1, and the first beater bracket 2 is movably arranged on the other side of the conveying device 1. The first beater bracket 2 can move towards the second beater 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 beater bracket 2 can move away from the second beater bracket 3 and reset. A movable push plate 4 is arranged on the first beater bracket 2. The push plate 4 can move away from the second beater bracket 3. An elastic buffer 5 is arranged on the first beater bracket 2. The elastic buffer 5 is connected to the push plate 4. The elastic buffer 5 can provide an elastic holding force for the push plate 4 to maintain the initial state. A plurality of push rods 6 are respectively and fixedly arranged on the push plate 4 and the second beater bracket 3. The lower end of the push rod 6 is fixedly connected to the push plate 4 or the second beater bracket 3. The upper end of the push rod 6 extends out of the conveying device 1. The push rod 6 is perpendicular to the roller. The upper end of the push rod 6 is higher than the roller. The push rod 6 is arranged between adjacent rollers. The push rods 6 on the push plate 4 are arranged in one-to-one correspondence with the push rods 6 on the second beater bracket 3. The push rods 6 on the push plate 4 can move along with the push plate 4. When the product 22 needs to be positioned, at this time, the product 22 is located on the conveying device 1 and is between the first beater bracket 2 and the second beater bracket 3. The first beater bracket 2 moves towards the second beater bracket 3. The push plate 4 moves along with the first beater bracket 2. The push rods 6 on the push plate 4 first contact the product 22 and push the product 22 so that the other end of the product 22 contacts the push rods 6 on the second beater bracket 3. At this time, the product 22 is subjected to forces on both sides. The first beater bracket 2 continues to move towards the second beater bracket 3. The push rods 6 on the push plate 4 apply 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 away from the second beater bracket 3, and at the same time apply a thrust to the elastic buffer 5 until the first beater bracket 2 drives the push plate 4 to move away from the second beater bracket 3 after the product 22 is reset. 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 beater bracket 2, and the other end of the spring is connected to the push plate 4.

[0042] It should be noted that by providing a movable push plate 4 and an elastic buffer 5 on the first clapper bracket 2, when the push plate 4 is stressed, it will move away from the second clapper bracket 3. At the same time, the elastic buffer will provide a thrust for the push plate 4 to keep the push plate 4 in contact with the product 22 all the time and drive the product 22 to rotate. When the push plate 4 moves, the stress on the product 22 can be reduced, preventing the product 22 from being broken at the edges or corners due to excessive stress.

[0043] As Figure 1 and Figure 2 shown, in some embodiments, the clapper positioning assembly further includes a blocking structure 7. The blocking structure 7 is arranged at the front end of the conveying device 1 during conveying. The blocking structure 7 has a plurality of blocking members 8. The blocking members 8 are in contact with the product 22 to limit the product 22. The contact surface of the blocking member 8 with 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 in 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 are in contact with the product 22. The contact surface of the blocking member 8 with the product 22 is an inclined surface, and the angle between the inclined surface and the product 22 is greater than 90°, so that the blocking member 8 is in point contact with the product 22. When the grasping device grasps the product 22, the side surface of the product 22 will not rub against the blocking member 8.

[0045] Preferably, in this embodiment, the blocking member 8 is a frustum 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 of the blocking member 8 with the product 22 as an inclined surface, and the angle between the inclined surface and the product 22 is greater than 90°, the blocking member 8 is in point contact with the product 22. When the product 22 is grasped by the grasping device and lifted, it will not rub against or collide with the blocking member 8, and the situation where the product 22 is broken at the edges or corners due to rubbing against or colliding with the blocking member 8 during the lifting process can be avoided.

[0047] As Figure 3 and Figure 4 shown, in some embodiments, the conveying device 1 has an avoidance position for setting a downwind knife. A plurality of transition guide wheels 9 are arranged in the avoidance position. The adjacent transition guide wheels 9 are arranged at intervals. The transition guide wheels 9 are in the same plane as the rollers. The transition guide wheels 9 are adapted to contact the bottom surface of the product 22 and drive the product 22 to move.

[0048] In this embodiment, a plurality of transition guide wheels 9 are arranged in the avoidance position. The plurality of transition guide wheels 9 are arranged at intervals along the extending direction of the avoidance position. The transition guide wheels 9 are driven wheels. The transition guide wheels 9 are in contact with the bottom of the product 22 and provide a supporting force for the bottom of the product 22. The transition guide wheels 9 cooperate with the rollers to drive the product 22 to move.

[0049] It should be noted that by providing the transition idler wheel 9 within the avoidance position, the product 22 is supported by the transition idler wheel 9 when passing through the lower air knife, preventing the problem of breakage of the product 22 due to lack of support.

[0050] As Figure 3 and Figure 4 shown, in some embodiments, a pressure wheel assembly 10 is provided on the conveying device 1. The pressure wheel assembly 10 is arranged on both sides of the upper air knife. The pressure wheel assembly 10 is parallel to the roller, and the pressure wheel assembly 10 contacts the upper surface of the product 22 and cooperates with the roller to limit the position of the product 22.

[0051] In this embodiment, a pressure wheel assembly 10 is provided above the conveying device 1. The pressure wheel assembly 10 is arranged on both sides of the upper and lower air knives. 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 for the product 22 to pass through between the pressure wheel and the roller. 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 faces of the product 22 and provide a clamping force to the product 22, so that the product 22 moves stably on the roller. The pressure wheel is a driven wheel. The product 22 drives the pressure wheel to rotate, the pressure wheel drives the rotating shaft to rotate, and both ends of the rotating shaft are rotatably arranged on the two side walls of the conveying device 1.

[0052] It should be noted that by providing the pressure wheel, the pressure wheel and the roller can provide a clamping force to the product 22, preventing the problem that the product 22 is blown by the upper and lower air knives and disengages from the roller, resulting in broken pieces.

[0053] As Figure 3 and Figure 4 shown, in some embodiments, a plurality of guide wheels 11 are respectively arranged on both sides of the conveying device 1. The adjacent guide wheels 11 are arranged at intervals, and the guide wheels 11 contact the product 22 to limit the position of the product 22.
