Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] Please refer to Figures 1-7 This invention provides a substrate transfer device with automatic cross-opening and stretching capability, comprising: a support frame 1, two sets of clamping assemblies 2, an opening clamp 3 for driving the clamping assemblies 2 to open, and a moving drive 4 for driving the support frame 1 to move horizontally. Specifically, the moving drive 4 is a drive roller (its drive device is not shown in the accompanying drawings). The two sets of clamping assemblies 2 are symmetrically arranged at both ends of the support frame 1. The two sets of clamping assemblies 2 cooperate to clamp the substrate 5. Under the action of the moving drive 4, the support frame 1, the two sets of clamping assemblies 2, and the substrate 5 move horizontally. When the substrate moves to one side of the opening clamp 3, the clamping member at the corresponding position in the clamping assembly 2 contacts the opening clamp 3, and under the action of the opening clamp 3, it opens, thus realizing the opening of the opening clamp 3.

[0028] Specifically, in this embodiment, the clamping assembly 2 is provided with a plurality of clamping members, the clamping members including: a fixed shaft 20, a ball jaw 21 rotatably mounted on the fixed shaft 20, an elastic reset member 22 connected to one end of the ball jaw 21, and a fixed jaw 23 cooperating with the ball jaw 21. The fixed jaw 23 is mounted on the support frame 1, and the fixed jaw 23 and the ball jaw 21 respectively clamp the two sides of the substrate 5; the opening clamping member 3 includes: an opening clamping part and a rotary drive device 30 for driving the opening clamping part to rotate. The operation of the substrate 5 transfer device with automatic cross-opening and stretching in this invention is as follows: The substrate 5 is clamped by two sets of clamping components 2. The opening clamp 3 is set on one side of the clamping components 2. The moving drive 4 drives the support plate, clamping components 2, and substrate 5 to move towards the side closer to the clamping components 2. When the ball jaw 21 of the clamping component contacts the opening clamp, the opening clamp will apply a force to the ball jaw 21 under the action of the rotation drive 30. The ball jaw 21 rotates on the fixed shaft 20, the elastic reset component 22 undergoes elastic deformation, and one end of the ball jaw 21 separates from the substrate 5. The substrate 5 is rinsed with chemical solution before and after cleaning to clean the clamping points. After cleaning, the support plate, clamping assembly 2, and substrate 5 are moved as a whole by the moving drive 4. The ball gripper 21 at the corresponding position separates from the clamping part. Under the action of the elastic reset member 22, the ball gripper 21 is reset. The ball gripper 21 and the fixed gripper 23 cooperate to clamp the substrate 5. With further movement, the clamping part at the next position will contact the clamping part 3. The above process is repeated to achieve rapid cleaning of the clamping points on the substrate 5, effectively avoid the problem of substrate 5 contamination, improve product quality, and effectively improve product yield.

[0029] Specifically, in this embodiment, the elastic reset member 22 includes: a connecting shaft 220 connected to the ball gripper 21, a spring 221 connected to the connecting shaft 220, and a fixing part 222 connected to the support frame 1. One end of the spring 221 is rotatably connected to the fixing part 222. When the ball gripper 21 opens, the connecting shaft 220 and the spring 221 move together with the ball gripper 21. The spring 221 stretches, ensuring the normal opening of the ball gripper 21 and also providing a buffering effect. When the ball gripper 21 separates from the opening part, the spring 221 causes the ball gripper 21 to close quickly.

[0030] Specifically, in this embodiment, the ball gripper 21 includes: a pressing part 210, a rotating part 211 connected to the pressing part 210, a clamping part 212 connected to the rotating part 211, and a ball 213 disposed on the pressing part 210. The clamping part 212 cooperates with the fixed gripper 23 to clamp the substrate 5. Anti-slip textures are provided on the surfaces of the clamping part 212 and the fixed gripper 23 that contact the substrate 5 to ensure stability after clamping the substrate 5. The opening part contacts the ball 213 on the pressing part 210. Under the dual action of the rotational force of the opening part and the movement of the clamping assembly 2 driven by the moving drive 4, the opening part contacts different positions on the ball 213, thereby applying a stable pressure to the pressing part 210, causing the ball gripper 21 to open quickly.

[0031] Specifically, in this embodiment, the support frame 1 is provided with a movable plate 10 and a fixed plate 11, and the two sets of clamping components 2 are respectively installed on the movable plate 10 and the fixed plate 11; the support frame 1 is provided with a plurality of slots 12 at equal intervals, and both ends of the movable plate 10 are provided with a locking block 13 that cooperates with the slot 12. When the movable plate 10 is located in the slots 12 at different heights on the support frame 1, its height is different; the movable plate 10 is installed on the support frame 1 through the slots 12. The position of the movable plate 10 on the support frame 1 can be adjusted to accommodate the clamping of substrates 5 of different sizes. It is compatible with the transfer and clamping of substrates 5 of different sizes, making it highly practical. During adjustment, a force is directly applied to the movable plate 10 to move it upward or downward. After it reaches the slot 12 at the designated position, the slot 12 clamps the locking block 13 to fix the movable plate 10, thus achieving rapid adjustment of the position of the movable plate 10 and the clamping assembly 2. Of course, in order to ensure the stability after the position adjustment, according to actual needs, after the position of the movable plate 10 is adjusted, fixing screws or other fasteners or locking devices can be added to further fix the movable plate 10 to ensure its stability after adjustment.

[0032] Specifically, in this embodiment, the clamping part includes: a shaft 31 connected to the output end of the rotary drive device 30, and two clamping rollers 32 sleeved on the shaft 31. The two clamping rollers 32 respectively cooperate with two sets of clamping components 2 and are disposed on one side of them. Specifically, when the clamping rollers 32 are in operation, they contact the balls 213 on the ball jaws 21 to ensure the stability of the clamping part and the clamping components 2. Specifically, the rotary drive device 30 is a servo motor.

[0033] In summary, the present invention provides a substrate transfer device capable of automatic cross-opening and stretching, which has the following beneficial effects:

[0034] 1. A force is applied to the ball gripper by the clamping mechanism. The ball gripper rotates on the fixed shaft, and the elastic reset component undergoes elastic deformation. One end of the ball gripper separates from the substrate. The clamping points on the substrate are rinsed with chemicals to clean the clamping points. After cleaning, the support plate, clamping assembly, and substrate are moved as a whole by the moving drive component. The corresponding ball gripper separates from the clamping mechanism. Under the action of the elastic reset component, the ball gripper resets. The ball gripper and the fixed gripper cooperate to clamp the substrate, thereby achieving rapid cleaning of the clamping points on the substrate, effectively avoiding substrate contamination, improving product quality, and effectively increasing product yield.

[0035] 2. The position of the movable plate on the support frame is adjustable, thereby adjusting the distance between the two clamping components to accommodate the clamping of substrates of different sizes. It is compatible with the transfer and clamping of substrates of different sizes, and has strong compatibility.
