[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution:

[0025] An adaptive corner protection type LCD screen assembly equipment includes an assembly production line unit 1. The assembly production line unit 1 is equipped with a feeding mechanism 2 for clamping and moving the four corners of the display screen. The feeding mechanism 2 includes:

[0026] The clamping unit 21 is positioned above the assembly line unit 1 and is used to move the display screen.

[0027] The adapter unit 22 is located below the clamping unit 21 and includes two mounting brackets 221. Both ends of the mounting bracket 221 are fixedly mounted with limit brackets 2210. The surface of the limit bracket 2210 is slidably mounted with a movable seat 227. The lower end of the movable seat 227 is fixedly mounted with a right-angle block 228 through a rectangular groove. The inside of the right-angle block 228 is fixedly mounted with a rubber pad 229. The two movable seats 227 drive the two right-angle blocks 228 to move synchronously to clamp the display screen. The rubber pad 229 clamps the four corners of the display screen to achieve protective clamping of the four corners of the display screen.

[0028] In this embodiment, two T-shaped bars 222 are fixedly installed on the top of the inner cavity of the mounting bracket 221. A first rack 223 and a second rack 224 are slidably installed on the two T-shaped bars 222 respectively. A servo motor 225 is fixedly installed in the middle of the top of the T-shaped bars 222. The output end of the servo motor 225 passes through the T-shaped bars 222 and a gear 226 is fixedly installed thereon. The gear 226 meshes with the first rack 223 and the second rack 224. The first rack 223 and the second rack 224 move towards each other and in opposite directions by rotating the gear 226. Two moving seats 227 are fixedly installed at the bottom of the two ends of the first rack 223 and the second rack 224 respectively. The adapter unit 22 is rotated below the clamping unit 21 by the rotating component 4.

[0029] Two T-shaped bars 222 are fixedly installed on the top of the inner cavity of the mounting bracket 221, and a first rack 223 and a second rack 224 are slidably installed on them respectively. With the gear 226 at the output end of the servo motor 225 at the top of the T-shaped bars 222 meshing with them, the first rack 223 and the second rack 224 can move precisely in opposite directions, thereby driving the moving seat 227 fixed at its bottom to move synchronously. Finally, the right-angle block 228 forms an adaptive clamping of the four corners of the display screen. Its function is to significantly improve the centering, stability and adaptability of the clamping to display screens of different sizes, and effectively prevent corner damage caused by misalignment or uneven force.

[0030] In this embodiment, the rotating assembly 4 includes two fixed plates 41. A third motor 44 and a first rotating rod 45 are rotatably mounted inside the fixed plates 41, and second rotating rods 46 are fixedly mounted on the surfaces of the third motor 44 and the first rotating rod 45, respectively. The two second rotating rods 46 are fixedly mounted on the bottom of the inner cavity of the mounting bracket 221, and one end of the third motor 44 passes through the fixed plate 41 and is fixedly mounted on a second motor 42. The second motor 42 is fixedly mounted on one side of the fixed plate 41. A limit groove 43 is formed inside the first rotating rod 45, and the third motor 44 is slidably inserted into the inside of the first rotating rod 45.

[0031] The rotating assembly 4 is connected to the bottom of the inner cavity of the mounting bracket 221 by a third motor 44 and a first rotating rod 45 respectively rotatably installed in two fixed plates 41, and by a second rotating rod 46 fixedly installed on its surface. At the same time, one end of the third motor 44 is driven by the second motor 42 and can be slidably inserted through the limiting groove 43 in the first rotating rod 45. This realizes the flexible and stable rotation and position adjustment of the adapter unit 22 as a whole. Its effect is to enhance the adaptability to various placement angles and work positions of the display screen, and improve the flexibility of the overall layout of the equipment and the coordination of the assembly process.

[0032] In this embodiment, the adapter unit 22 includes a track 211. A movable frame 212 is slidably mounted on the top of the track 211 via a movable component 3. Sliding blocks 213 are slidably mounted inside the left and right sides of the movable frame 212. Cylinders 2112 are fixedly mounted on the left and right sides of the movable frame 212. The output end of the cylinder 2112 passes through the cylinder 2112 and is fixedly connected to the sliding block 213. A fixed frame 2110 is slidably mounted inside the sliding block 213. The bottom end of the fixed frame 2110 is fixedly connected to the fixed plate 41. A rotating sleeve 215 is rotatably mounted inside the sliding block 213. A lead screw 214 is fixedly mounted inside the fixed frame 2110. The lead screw 214 is threadedly rotatably mounted inside the rotating sleeve 215.

[0033] The adapter unit 22 is connected to the output end of the cylinder 211 via the movable frame 212 slidably mounted on the top of the track 211 via the movable component 3, and the sliding block 213 slidably mounted inside it. With the screw drive of the rotating sleeve 215 rotatably mounted inside the sliding block 213 and the fixed frame 2110 with the screw rod 214 fixed inside, the height and horizontal position of the mounting frame 221 can be precisely adjusted. Its function is to quickly and accurately position the clamping mechanism above the display screen, ensure the consistency of the starting position of the clamping action, and thus improve the assembly accuracy and efficiency.

[0034] In this embodiment, a rotating rod 2113 is rotatably mounted above the movable frame 212. A secondary synchronous pulley 218 is fixedly mounted on the left end surface of the rotating rod 2113. A fourth motor 219 is fixedly mounted on the top left side of the track 211. The active synchronous pulley at the output end of the fourth motor 219 is connected to the secondary synchronous pulley 218 through a synchronous belt 217. A fourth motor 219 is fixedly mounted above the movable frame 212. A first helical gear 216 is fixedly mounted on the surface of the rotating sleeve 215. A second helical gear 2111 is fixedly mounted on the surface of the rotating rod 2113. The first helical gear 216 and the second helical gear 2111 are meshed together.

[0035] The rotating rod 2113, which is rotatably mounted above the movable frame 212, and its secondary synchronous wheel 218 at its left end, work in conjunction with the active synchronous wheel at the output end of the fourth motor 219 on the top left of the track 211, which is driven by the synchronous belt 217. At the same time, the rotational motion is converted into the rotation of the rotating sleeve 215 by the meshing of the first helical gear 216 on the surface of the rotating sleeve 215 and the second helical gear 2111 on the rotating rod 2113. This drives the lead screw 214 to lift and lower the fixed frame 2110. The effect is to realize the automated and synchronous adjustment of the height of the adapter unit 22, ensuring that the clamping mechanism can adapt to displays of different thicknesses or heights, and improving the versatility and automation level of the equipment.

[0036] In this embodiment, a set of movable wheels 33 are rotatably installed on both the front and rear sides of the movable frame 212. A pulley 32 is fixedly installed on the left movable wheel 33 at the front left end of the movable frame 212. A first motor 31 is fixedly installed on the top left side of the movable frame 212. The active pulley at the output end of the first motor 31 is connected to the pulley 32 through a belt 34.

[0037] The movable wheels 33 rotatably mounted on the front and rear sides of the movable frame 212 and the pulley 32 fixed on the left front movable wheel 33, together with the active pulley at the output end of the first motor 31 on the top left of the movable frame 212, are driven by the belt 34, realizing the smooth and controllable movement of the entire movable frame 212 and the upper adapter unit 22 on the track 211. Its function is to ensure that the feeding mechanism 2 runs smoothly and is accurately positioned during the conveying of the display screen, effectively reducing shaking and offset, thereby ensuring the stability of the display screen position and the reliability of the conveying during the assembly process.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] During operation, the fourth motor 219 drives the secondary synchronous pulley 218 to rotate via the synchronous belt 217. The secondary synchronous pulley 218 drives the sliding block 213 to rotate, which in turn drives the two fourth motors 219 to rotate. The fourth motors 219 drive the first helical gear 216 to rotate, which in turn drives the rotating sleeve 215 to rotate. The rotating sleeve 215 moves the fixed frame 2110 up and down, moving the adapter unit 22 above the display screen. The two cylinders 2112 move the sliding block 213 to move, causing the mounting frame 221 to move synchronously. As the mounting frame 221 moves, the servo motor 225 drives the gear 226 to rotate. The gear 226 drives the first rack 223 and the second rack 224 to move synchronously. The first rack 223 and the second rack 224 drive the two moving seats 227 to move synchronously. The moving seats 227 drive the right-angle block 228 to move, causing the right-angle block 228 to clamp the four corners of the display screen.

[0040] Then, the first motor 31 runs and drives the pulley 32 to rotate via the belt 34. The pulley 32 drives the moving wheel 33 to move on the track 211, so that the feeding mechanism 2 drives the display screen to move.
