Description

Technical Field

[0001] The invention relates to the technical field of material feeding and conveying, and in particular to a material feeding and conveying device used for processing liquid crystal display screens. Background Art

[0002] In the production process of LCD screens, multiple components need to be assembled together precisely, including glass substrates, color filters, polarizers, etc. In order to improve production efficiency and ensure product quality, automated production lines have become an indispensable part. Among them, the feeding and conveying equipment is used to transport the various components of the LCD screen from one process to the next, ensuring the smooth progress of the entire production process.

[0003] At present, the feeding and conveying equipment in the processing of LCD screens usually adopts a conveyor belt or roller system to realize the transportation of materials. These devices drive the rollers to rotate through motors, driving the LCD screen components placed on them to move along a predetermined path. However, the existing feeding and conveying equipment is not equipped with an effective buffer device in actual application. When encountering sudden start or emergency stop, due to inertia, the LCD screen components on the conveying surface may be displaced or collided. Especially in the case of high-speed operation, this inertia effect is more obvious, so the impact force cannot be reduced in time, which is easy to cause damage to the LCD screen components. Especially for thin and brittle glass substrates, this impact may cause cracks or even breakage, which will increase the breakage rate of LCD screen components, leading to an increase in production costs, while affecting the quality and reliability of the product. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1: A feeding and conveying device for processing a liquid crystal display screen, such as Figure 1-Figure 4 As shown, it includes a bottom plate 101, an electric slide rail 102 is fixedly connected to the top of the bottom plate 101, a slider of the electric slide rail 102 is fixedly connected to a connecting plate 103, a sliding plate 104 is slidably connected to the connecting plate 103 along the left and right directions, and connecting frames 1041 symmetrically distributed along the front and back of the sliding plate 104 are fixedly connected to the top and left and right sides of the sliding plate 104, and the connecting frame 1041 is rotatably connected to a first rotating frame 105, the first rotating frame 105 is set as a V-shaped frame, and the angle of the first rotating frame 105 is set to 90 degrees. A first torsion spring 106 is fixedly connected between the connecting frame 1041 and the adjacent first rotating frame 105, and the left and right sides of the sliding plate 104 The sides are fixedly connected with a fixing frame 107 which is symmetrically distributed along the sliding plate 104, and the fixing frame 107 is rotatably connected with a first roller 108 which is symmetrically distributed up and down along the fixing frame 107. The front and rear parts on the left and right sides of the connecting plate 103 are fixedly connected with spring pieces 109 which are symmetrically distributed up and down along the connecting plate 103, and the first roller 108 is squeezed and fitted with the adjacent spring pieces 109. An elastic elastic buffer frame 110 is fixedly connected to the middle of the fixing frame 107, and the front and rear parts on the left and right sides of the connecting plate 103 are fixedly connected with a blocking frame 111 which is symmetrically distributed up and down along the elastic buffer frame 110, and the blocking frame 111 is squeezed and fitted with the adjacent elastic buffer frame 110.

[0031] First, the LCD screen is placed between the four first rotating frames 105. Under the action of the gravity of the LCD screen, the side of the first rotating frame 105 that contacts the LCD screen swings to be parallel to the sliding plate 104. When the first rotating frame 105 swings around the connecting frame 1041, the first torsion spring 106 twists and deforms. Then, the electric slide rail 102 is started to drive the connecting plate 103 to move right, thereby driving the components on the connecting plate 103 and the LCD screen to move right, achieving the effect of conveying the LCD screen for loading. After the loading and conveying is completed, the electric slide rail 102 drives the connecting plate 103 to move left, thereby driving the components on the connecting plate 103 to move left and reset, and so on and so forth until the loading and conveying of all LCD screens is completed, and finally the electric slide rail 102 is closed.

[0032] In the above process, when the connecting plate 103 stops suddenly when being transported to the right, the sliding plate 104 drives the fixing frame 107, the first roller 108 and the elastic buffer frame 110 to continue to move to the right due to inertia, and the elastic buffer frame 110 on the right side moves to the right along the blocking frame 111 on the right side, and at the same time, the first roller 108 on the right side opens the spring sheet 109 on the right side, so that the sliding plate 104 stops moving to the right slowly. At this time, the spring sheet 109 on the right side is reset to make the first roller 108 on the right side move to the left, thereby driving the fixing frame 107 to move to the left, and then driving the elastic buffer frame 110 on the right side to move to the left along the blocking frame 111, and because the blocking frame 111 The return slope is steeper, so the resistance to the elastic buffer frame 110 is greater, so that the fixed frame 107, the sliding plate 104, the connecting frame 1041, the first rotating frame 105 and the liquid crystal display screen reset more slowly. Similarly, at the moment when the connecting plate 103 continues to transport to the right, the spring piece 109 on the left is stretched out to play a buffering role, and the blocking frame 111 on the left has a resistance and deceleration effect on the elastic buffer frame 110 on the left. In this way, the present invention buffers the inertia at the start and end of transportation through the cooperation of the first roller 108 and the spring piece 109, and the cooperation of the blocking frame 111 and the elastic buffer frame 110, thereby reducing the damage of the inertia to the liquid crystal display screen.

[0033] Embodiment 2: Based on embodiment 1, Figure 5 and Figure 6As shown, it also includes a connecting ring 201 corresponding to the connecting frame 1041, the connecting ring 201 is connected to the corresponding connecting frame 1041, the middle of the top of the connecting ring 201 is set as a concave surface, and the two sides of the top of the connecting ring 201 are set as convex surfaces. The top of the first rotating frame 105 is rotatably connected to the second rotating frame 202, and a second torsion spring 203 is fixedly connected between the first rotating frame 105 and the adjacent second rotating frame 202. The second rotating frame 202 is fixedly connected to a first rotating rod on one side close to the adjacent connecting ring 201 204, the first rotating rod 204 is rotatably connected to the second roller 205 on one side close to the adjacent connecting ring 201, the second roller 205 contacts the top of the connecting ring 201, the connecting ring 201 is used to lift the second roller 205, the second rotating frame 202 is rotatably connected to the third rotating frame 206, the third rotating frame 206 is slidably connected to the flexible pressing frame 207, and the third rotating frame 206 and the adjacent flexible pressing frame 207 are fixedly connected with springs 208 symmetrically distributed along the third rotating frame 206.

[0034] When the liquid crystal display screen is placed between the four first rotating frames 105, the first rotating frame 105 drives the second rotating frame 202, the second torsion spring 203, the first rotating rod 204, the second roller 205, the third rotating frame 206, the flexible pressing frame 207 and the spring 208 to rotate. During the rotation process, the second roller 205 is guided by the guide slope of the connecting ring 201, so that the first rotating rod 204 drives the second rotating frame 202 to rotate relative to the first rotating frame 105, the second torsion spring 203 is twisted and deformed, and the second rotating frame 202 drives the third rotating frame 206, the flexible pressing frame 207 and the spring 208 to move closer to the liquid crystal display screen. One side of the top surface of the screen rotates until the third rotating frame 206 drives the flexible pressing frame 207 to rotate freely to fit with the top surface of the liquid crystal display screen, thereby achieving the effect of limiting protection for the top of the liquid crystal display screen, and at the start and end of transportation, the liquid crystal display screen drives the flexible pressing frame 207 to slide left and right adaptively relative to the third rotating frame 206 due to inertia, and the spring 208 adaptively deforms and resets to reduce the stress damage to the liquid crystal display screen caused by inertia. When the liquid crystal display screen is removed, the flexible pressing frame 207 is pushed to move upward, so that the second rotating frame 202 and the third rotating frame 206 and other components rotate in the opposite direction and reset.

[0035] like Figure 5 and Figure 7 As shown, a pushing frame 301 corresponding to the connecting ring 201 is also included. The pushing frame 301 is fixedly connected to one side of the connecting plate 103 close to the corresponding connecting ring 201 . A third torsion spring 209 is sleeved between the connecting frame 1041 and the adjacent connecting ring 201 .

[0036] In order to prevent the liquid crystal display screen and the sliding plate 104 from being greatly offset in relative position due to inertia, and to prevent the display screen from colliding with the sliding plate 104 due to inertia, the specific operation is as follows: for example, when the electric slide rail 102 generates inertia at the moment of emergency stop, the sliding plate 104 begins to deviate to the right due to inertia, thereby driving the connecting frame 1041, the first rotating frame 105, the connecting ring 201 and other components to deviate to the right. In the process of the connecting ring 201 moving to the right, it contacts the pushing frame 301, thereby driving the connecting ring 201 to rotate counterclockwise, and the third torsion spring 209 is deformed by force, thereby driving the second roller 205 and the first rotating rod 204 to continue to rotate clockwise, thereby driving the second rotating frame 202 and the third rotating frame 206 and the spring 208 The force is finally transmitted to the flexible pressing frame 207, which is converted into appropriate pressure to press the LCD screen through the flexible pressing frame 207, thereby reducing the deviation amplitude of the LCD screen. In the process of the LCD screen moving to the right due to inertia, the inertia force of the screen is further absorbed by the compression of the spring 208. When the inertia force of the screen itself is offset, the flexible pressing frame 207 is pushed to reset during the process of the spring 208 resetting, so as to drive the screen to move and reset to the initial placement position, and correct the deviation of the screen. As the sliding plate 104 is pushed back to the initial position by the spring 109, the connecting ring 201 is disengaged from the pushing frame 301, the torsion spring is deformed and reset, and then the connecting ring 201 is pushed to rotate clockwise to the initial position.

[0037] Embodiment 3: Based on embodiment 2, Figure 8 and Fig. 9 As shown, it also includes a second rotating rod 401 corresponding to the second rotating frame 202, the second rotating rod 401 is fixedly connected to the side of the second rotating frame 202 away from the first rotating rod 204, the second rotating rod 401 is rotatably connected to the connecting rod 402, the first rotating frame 105 is rotatably connected to the third rotating rod 403, the third rotating rod 403 is rotatably connected to the adjacent connecting rod 402, the third rotating rod 403 is fixedly connected to the guide ring 404 symmetrically distributed along the third rotating rod 403, the first rotating frame 105 is slidably connected to the anti-collision frame 405 along the front and rear directions, the anti-collision frame 405 is used to limit the outer side of the liquid crystal display screen, the guide ring 404 is provided with a guide groove, the guide ring 404 is slidably connected to the adjacent anti-collision frame 405 through the guide groove, the guide groove of the guide ring 404 is used to guide the anti-collision frame 405 so that the anti-collision frame 405 slides toward the side close to the liquid crystal display screen.

[0038] When the second rotating frame 202 rotates relative to the first rotating frame 105, the second rotating frame 202 drives the second rotating rod 401 to rotate, and the second rotating rod 401 pulls the third rotating rod 403 to rotate through the connecting rod 402, thereby driving the guide ring 404 to rotate, and the guide ring 404 pushes the anti-collision frame 405 to move close to the outer side of the liquid crystal display screen through the guide groove, so that the anti-collision frame 405 is close to the outer side of the liquid crystal display screen, and the outer side of the liquid crystal display screen is limited and protected.

[0039] When the second rotating frame 202 rotates in the opposite direction relative to the first rotating frame 105, the second rotating frame 202 drives the second rotating rod 401 to rotate in the opposite direction, and the second rotating rod 401 pulls the third rotating rod 403 to rotate in the opposite direction through the connecting rod 402, thereby driving the guide ring 404 to rotate in the opposite direction, and the guide ring 404 pulls the anti-collision frame 405 to move to the outer side away from the liquid crystal display screen and reset through the guide groove.

[0040] like Fig.10 As shown, a buffer plate 501 is also included. The buffer plate 501 is fixedly connected to the adjacent first rotating frame 105. The buffer plate 501 is used to buffer and limit the bottom side of the liquid crystal display screen.
