When the measuring mechanism 3 measures the thickness change of the screen 1, the detecting mechanism 4 of the invention automatically adjusts the angle, so that the position of the upper surface of the screen 1 is always detected by the detecting mechanism 4; meanwhile, the distance between the repairing mechanism 5 and the screen 1 is automatically adjusted, so that the distance between the repairing mechanism 5 and the screen 1 is minimum, the repairing time of the repairing mechanism 5 is shortened, and the repairing efficiency is improved; according to the invention, the clamping force on the screen 1 during repair is automatically adjusted according to the thickness change of the glass of the detected screen 1, so that the damage to the screen 1 caused by overlarge clamping force is avoided, the condition that the screen 1 cannot be fixed due to too small clamping force is avoided, and the qualification rate of the screen 1 is improved.

As shown in fig. 2, when the present invention is in operation, when the screen 1 passes through the detecting mechanism 4, the laser emitted from the light source emitting end 41 is emitted by the screen 1 and then reflected to the light source receiving end. If the screen 1 is intact and has no scratch, the laser emitted by the light source emitting end 41 is just received by the light source receiving end after being emitted by the screen 1, and the screen 1 continues to move; if the light source receiving end does not receive the reflected laser, the screen 1 is provided with a scratch, the scratch changes the reflection angle of the laser, and the repairing mechanism 5 starts repairing the screen 1. The method has high detection accuracy.

In operation of the invention, as shown in figure 3, the screen 1 is transported by the conveyor 2 past the measuring means 3. The screen 1 passes the pinch roller 31, the pinch roller 31 is moved vertically upward by being pushed up by the screen 1, the first slide plate 32 is moved upward, and the first compression spring 33 is stretched. The distance that the first sliding plate 32 moves upward at this time is the thickness of the screen 1.

As shown in fig. 3, 4 and 5, when the present invention is in operation, the specific repair process of the repair mechanism 5 is as follows: the driving motor 55 drives the screw rod 52 to rotate according to a signal received by the detection mechanism 4, the screw rod 52 drives the dropper 53 to move to the position above the scratch of the screen 1, then the dropper 53 loaded with the screen 1 repairing liquid drips the screen 1 repairing liquid downwards to fill the scratch on the screen 1, and then the flexible scraper 57 scrapes the screen 1 repairing liquid when the screen 1 moves past the bottom end of the limiting plate 54. According to the invention, when the detection mechanism 4 detects the scratch of the screen 1, the repair mechanism 5 is driven to automatically repair the scratch of the screen 1, so that the qualification rate of products is improved, the rejection rate of the products is reduced, and the cost is saved.
In a further aspect of the present invention, the two ends of the screw 52 are rotatably mounted on the first sliding block 58, and the first sliding block 58 is fixedly connected to the first sliding plate 32.
The repairing mechanism 5 of the invention needs to automatically adjust the distance between the repairing mechanism 5 and the screen 1 according to the thickness of the screen 1, so that the distance between the repairing mechanism 5 and the screen 1 is minimum. As shown in fig. 3, the distance between the repair mechanism 5 and the screen 1 is initially adjusted to the illustrated distance. According to the invention, when the measuring mechanism 3 measures the thickness of the screen 1 and the thickness of the screen 1 changes, the first sliding plate 32 drives the first sliding block 58 to move upwards by the same distance, so that the distance between the repairing mechanism 5 and the screen 1 can be always kept to be minimum, and thus the distance for dropping the repairing liquid of the screen 1 by the dropper 53 is minimum, so that the repairing time is saved, the repairing efficiency is improved, the chances of external pollution and external deviation of the repairing liquid of the screen 1 in the dropping process are avoided as much as possible, and the repairing effect is ensured.
As a further scheme of the invention, the clamping unit 51 comprises a supporting plate 511 horizontally and slidably mounted on the frame, the sliding direction of the supporting plate 511 is perpendicular to the conveying direction of the screen 1, a clamping piece 512 is further horizontally and slidably mounted on the conveying belt 2, and the sliding direction of the clamping piece 512 is consistent with the sliding direction of the supporting plate 511; a first compression spring 513 is provided between the chucking member 512 and the support plate 511 in the sliding direction of the chucking member 512; a third compression spring 514 is provided between the support plate 511 and the frame in the sliding direction of the support plate 511; a fixed rod 515 is fixedly installed on the first sliding plate 32, and a first wedge surface 516 is formed on the fixed rod 515; a second wedge surface 517 corresponding to the first wedge surface 516 is formed on the supporting plate 511; the lower end of the clamping piece 512 is provided with a groove 518, a limiting rod 519 inserted into the groove 518 is vertically installed on the rack in a sliding mode, a third wedge face 5191 is arranged on one side, close to the supporting plate 511, of the upper end of the limiting rod 519, and a fourth wedge face 5181 corresponding to the third wedge face 5191 is arranged on the groove 518.
According to the invention, when the repairing mechanism 5 is repaired, the screen 1 on the conveying belt 2 needs to be clamped and fixed firstly, so that the repairing mechanism 5 is convenient to repair. As shown in fig. 6 and 7, in the operation of the present invention, initially, the stopper rod 519 restricts the horizontal movement of the clamp 512, the detection mechanism 4 detects the scratch on the screen 1, at this time, the stopper rod 519 contracts, and the clamp 512 moves to clamp the screen 1 by the restoring force of the first compression spring 513 to fix the screen 1. When the repair is completed, the stopper rod 519 ascends, the third wedge surface 5191 on the stopper rod 519 also ascends, and the clamping piece 512 is driven to reset through the fourth wedge surface 5181. The present invention also enables the amount of clamping force of the clamping member 512 to be adjusted according to the thickness of the screen 1. When the thickness of the screen 1 is increased, the upward moving distance of the first sliding plate 32 is increased, the fixed rod 515 moves upward, the supporting plate 511 moves towards the direction close to the first sliding rod under the restoring force of the third compression spring 514, and the deformation amount of the first compression spring 513 is reduced, so that when the clamping member 512 clamps, the clamping force of the clamping member 512 is reduced, the screen 1 is prevented from being damaged due to overlarge clamping force, the screen 1 is protected, and the cost is saved; when the thickness of the screen 1 is reduced, the supporting plate 511 is driven by the fixing rod 515 to move away from the first sliding rod, and the deformation amount of the first compression spring 513 is increased, so that when the clamping member 512 clamps, the clamping force of the clamping member 512 is increased, the situation that the screen 1 cannot be fixed due to the fact that the clamping force is too small is avoided, and the qualified rate of the screen 1 is improved.
