[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, by arranging the cooperation between the first drive motor and the first one-way screw and other parts, the output end of the hydraulic cylinder drives the detection collision head to move downward to collide with the mobile phone screen. When it is necessary to detect different positions of the mobile phone screen, the first drive motor is started intermittently, and the first drive motor intermittently drives the first one-way screw to rotate, thereby driving the first slider to drive the detection collision head to move intermittently, so as to facilitate the detection collision head to move to different positions to perform strength detection on the mobile phone screen, thereby improving the accuracy of the mobile phone screen strength detection, and thus making the mobile phone screen strength detection data more accurate;

[0019] 2. In the present invention, a pressing mechanism is provided, and the output end of the second driving motor drives the connecting shaft to rotate the toggle column through the turntable, so that the toggle column slides inside the circular groove, and the circular frame is pushed by the circular groove to drive the second slider to move downward. The second slider moves downward and drives the pressing plate downward through the movable plate. When the pressing plate is in contact with the top of the mobile phone screen, the movable plate continues to move downward. When the bottom end of the movable plate is in contact with the top of the pressing plate, the second driving motor stops running. In this way, the broken mobile phone screen is fixed before the collision detection head performs detection at different positions, thereby avoiding displacement of the broken mobile phone screen when performing strength detection at different positions, thereby improving the accuracy of the collision detection head in detecting mobile phone screens at different positions.

[0020] 3. In the present invention, a fine-tuning component is provided to pull one end of the clamping column out of the clamping hole, and then the connecting ring is rotated. The connecting ring drives the second one-way screw to rotate, thereby driving the second slider to drive the toggle column to move downward, thereby adjusting the position of the toggle column, so that the toggle column rotates to move the circular frame to different positions, thereby making the position of the pressing plate adjustable, so that the device can perform strength testing on mobile phone screens of different thicknesses, thereby improving the overall practicality of the device;

[0021] 4. In the present invention, a calibration guard and a pulling unit are provided, and the pulling rope is wound when the connecting shaft rotates, thereby pulling the connecting plate to drive the two toggle rods to move toward the hemispherical block. The hemispherical block is pushed by the action of the inclined surface to drive the second guide block to approach the second slider through the power column. When the two pressure wheels respectively abut against both sides of the second slider, they clamp the two sides of the second slider to limit the second slider, thereby preventing the second slider from deflecting during the downward movement, so that the movable plate can stably move downward to the specified position, thereby improving the accuracy of the movement of the movable plate and preventing the movable plate from deflecting during the movement;

[0022] 5. The present invention provides a sweeping assembly; when the pressing plate is attached to the top of the mobile phone screen, the bottom end of the brush is attached to the top of the mobile phone screen, the inclined surface is separated from the hemispherical block, and the hemispherical block is against the outer wall of the toggle rod, while the pushing block is against the outer wall of the rectangular guide block. When the toggle rod continues to move, the pushing block is driven to move by the first guide block, the first rectangular block and the L-shaped guide block, thereby pushing the rectangular guide block to drive the brush to move toward the inside of the pressing plate, thereby cleaning the top of the mobile phone screen, preventing fragments or foreign matter on the mobile phone screen from accumulating at the position where strength testing is required, thereby improving the accuracy of the collision detection head.

[0023] 6. In the present invention, by providing a guide unit, when the rectangular guide block moves, it moves along the direction of the second guide groove through the ball bearings and the second guide wheel. The ball bearings and the second guide wheel reduce the friction generated by the movement of the rectangular guide block and provide guidance for the movement of the rectangular guide block, thereby preventing the rectangular guide block from deflecting during movement.

[0024] 7. In the present invention, a swinging grooming piece is provided. When the connecting plate makes a preliminary movement, the first rectangular block is driven to move toward the rectangular guide block through the first guide block, thereby driving the pushing block to approach the rectangular guide block through the L-shaped guide block. When the pushing block makes a preliminary movement, the rack drives the spur gear to rotate the worm. The rotation of the worm drives the worm wheel to rotate the swinging rod through the first rotating rod, the rectangular toggle rod and the second rotating rod. When the rack is separated from the spur gear, the swinging rod rotates 180 degrees and is stored in the inside of the storage groove. When the storage groove rotates, it sweeps the bristles on the bottom end of the brush to avoid impurities or mobile phone screen fragments remaining on the brush, so that the brush can better clean the top of the mobile phone screen later.

When the storage groove 755 rotates, the bristles on the bottom end of the brush 751 are swept to prevent impurities or mobile phone screen fragments from remaining on the brush 751, so that the brush 751 can better clean the top of the mobile phone screen later.

[0053] See also Figure 9 A rectangular groove matching the rectangular toggle rod 754 is provided on the inner side of the second rotating rod 753 , and the rectangular toggle rod 754 is arranged inside the rectangular groove, and the bottom end of the rectangular toggle rod 754 has not yet contacted the bottom end of the rectangular groove.

[0054] Example: When the bottom end of the pressing plate 704 is attached to the top of the mobile phone screen, the movable plate 705 continues to approach the pressing plate 704, so that the rectangular toggle rod 754 moves inside the groove. At the same time, when the first rotating rod 746 rotates, the second rotating rod 753 can be driven to rotate through the rectangular toggle rod 754.

[0055] The working principle of the present invention is as follows: first, the mobile phone screen that needs to be strength tested is placed on the inner side of the support frame 1 and directly below the pressing plate 704, and then the second driving motor 703 is started. The output end of the second driving motor 703 drives the connecting shaft 722 to rotate through the turntable 706, so that the toggle column 726 slides inside the circular groove 725, and the circular frame 707 is pushed by the circular groove 725 to drive the movable block 710 to move downward. The movable block 710 moves downward and drives the pressing plate 704 to move downward through the movable plate 705. When the pressing plate 704 is in contact with the top of the mobile phone screen, the movable plate 705 continues to move downward. When the bottom end of the movable plate 705 is in contact with the top of the pressing plate 704, the second driving motor 703 stops running.

[0056] When the connecting shaft 722 rotates, the pulling rope 719 is reeled in, thereby pulling the connecting plate 735 to drive the two toggle rods 713 to move toward the hemispherical block 738. The hemispherical block 738 is pushed by the action of the inclined surface 737 through the power column 739 to drive the second guide block 741 to move closer to the movable block 710. When the two pressing wheels 742 respectively abut against the two sides of the movable block 710, they hold the two sides of the movable block 710 tightly, thereby limiting the movable block 710, thereby preventing the movable block 710 from deflecting during the downward movement, so that the movable plate 705 can stably move downward to the specified position;

[0057] When the pressing plate 704 is attached to the top of the mobile phone screen, the bottom end of the brush 751 is attached to the top of the mobile phone screen, the inclined surface 737 is separated from the hemispherical block 738, and the hemispherical block 738 is against the outer wall of the toggle rod 713. At the same time, the pushing block 756 is against the outer wall of the rectangular guide block 709. When the toggle rod 713 continues to move, the pushing block 756 is driven to move by the first guide block 733, the first rectangular block 714 and the L-shaped guide block 717, thereby pushing the rectangular guide block 709 to drive the brush 751 to move toward the inside of the pressing plate 704, thereby cleaning the top of the mobile phone screen and preventing debris or foreign matter on the mobile phone screen from accumulating at the position where strength testing is required.

[0058] When the rectangular guide block 709 moves, it moves along the direction of the second guide groove 750 through the ball bearings 758 and the second guide wheel 759. The ball bearings 758 and the second guide wheel 759 reduce the friction generated by the movement of the rectangular guide block 709 and provide guidance for the movement of the rectangular guide block 709, thereby preventing the rectangular guide block 709 from deflecting during the movement.

[0059] When the connecting plate 735 makes a preliminary movement, the first rectangular block 714 is driven to move toward the rectangular guide block 709 through the first guide block 733, so that the pushing block 756 is driven to approach the rectangular guide block 709 through the L-shaped guide block 717. When the pushing block 756 makes a preliminary movement, the spur gear 749 is driven by the rack 748 to drive the worm 745 to rotate. The worm 745 rotates and drives the worm gear 747 to rotate through the first rotating rod 746, the rectangular toggle rod 754, and the second rotating rod 753, so that when the rack 748 is separated from the spur gear 749, the swing rod 752 rotates 180 degrees and is stored in the storage groove 755. When the storage groove 755 rotates, it sweeps the bristles on the bottom end of the brush 751 to prevent impurities or mobile phone screen fragments from remaining on the brush 751, so that the brush 751 can better clean the top of the mobile phone screen later.

[0060] When it is necessary to perform strength testing on mobile phone screens of different thicknesses, one end of the clamping post 731 is first pulled out from the inside of the clamping hole 729, and then the connecting ring 728 is rotated. The connecting ring 728 drives the second one-way screw 727 to rotate, thereby driving the second slider 724 to drive the toggle post 726 to move downward, thereby adjusting the position of the toggle post 726, so that the toggle post 726 can be rotated to move the circular frame 707 to different positions, thereby making the position of the pressing plate 704 adjustable, so that the device can perform strength testing on mobile phone screens of different thicknesses;

[0061] Then the hydraulic cylinder 5 is started, and the output end of the hydraulic cylinder 5 drives the detection collision head 6 to move downward to collide with the mobile phone screen, so that the strength of the mobile phone screen is tested by the detection collision head 6. When it is necessary to test the mobile phone screen at different positions, the first drive motor 2 is started intermittently, and the first drive motor 2 intermittently drives the first one-way screw 3 to rotate, thereby driving the first slider 4 to drive the detection collision head 6 to move intermittently, so as to move the detection collision head 6 to different positions to perform strength testing on the mobile phone screen.
