[0024] The base 6 can be used to support the bottom of the support rod 7, and the support rod 7 and the mounting part of the scanning component 1 can be connected by the electric push rod 8, so that the distance between the scanning component 1 and the support rod 7 can be adjusted, and the scanning range of the bottom of the scanning component 1 on the glass screen can be changed. The symmetrically arranged detection frame 4 can support one side of the infrared receiver 10, so that the infrared receiver 10 can receive the infrared signal emitted by the infrared transmitter 13, and then assist in judging whether the current glass screen and the inner ring 11 are offset from the predetermined value position. The reinforcement plate 23 can realize the connection between the inner ring 11 and the guide ring 2 to ensure the synchronous rotation of the inner ring 11 and the guide ring 2. The detection platform 5 can be used to support the bottom of the motor 17, and the motor 17 can drive the flat gear 16 to rotate stably. Then, through the engagement of the flat gear 16 and the flat gear 2 18, the flat gear 2 18 and the reinforcement plate 23 are driven to rotate synchronously, thereby changing the position of the inner ring 11 and the guide ring 2 on the top of the detection platform 5, realizing the position adjustment and calibration of the glass screen, and reducing the position deviation of the glass screen during subsequent scanning and detection.

[0025] Example 2: Figure 1 - Figure 4As shown, one side of the detection table 5 is fixedly connected to the support plate 3, the top of the support plate 3 is fixedly connected to the vertical plate 15, an arc groove is provided on one side of the vertical plate 15, the bottom of the guide ring 2 is rotatably connected to the base 6, and a control panel is provided on one side of the base 6. The bottom of the control panel is fixedly connected to the detection table 5, and one side of the vertical plate 15 is fixedly connected to the motor 2 20, and one end of the output shaft of the motor 20 is fixedly connected to the bevel gear 1 21, and the top of the bevel gear 1 21 is engaged with the bevel gear 2 22, and the bevel gear 2 22 is rotatably connected to the vertical plate 15.

[0026] The inspection table 5 can be used to support and reinforce one side of the support plate 3, and the support plate 3 can be used to support the bottom of the vertical plate 15. At the same time, the vertical plate 15 can also guide the rotation of the guide ring 2. The motor 2 20 is stably installed and used on one side of the vertical plate 15, and can be used as a power source to drive the bevel gear 1 21 to rotate stably. Through the engagement of the bevel gear 1 21 and the bevel gear 2 22, the bevel gear 2 22 is driven to rotate at the bottom of the auxiliary block 19. The synchronous rotation of the bevel gear 2 22 and the mounting part can realize the adjustment of the tilt angle of the scanning component 2 14, and then change the scanning range of the scanning component 2 14 on the top of the glass screen, reduce the blind spot during horizontal scanning, achieve full coverage of the top of the glass screen, and ensure the scanning effect.

[0027] The method of use and working principle of this device are as follows: first, place the glass screen to be inspected in the cavity surrounded by the inner ring 11 and the reinforcement plate 23, then loosen the limit blocks 9 on both sides, and the bottom of the limit block 9 slides on the reinforcement plate 23, and the spring of the telescopic rod drives the telescopic rod to extend and reset. At this time, one side of the limit block 9 is in contact with the glass screen, and the two limit blocks 9 clamp the side wall of the glass screen. At this time, the infrared transmitter 13 on one side of the fixed block 12 sends an infrared signal, and the infrared receiver 10 is used to determine whether the placement position of the glass screen is offset according to whether it can receive the signal. If the infrared receiver 10 does not receive the signal, the external control terminal determines that the glass screen has a position offset, and at this time, the motor 17 is used to drive the flat gear 16 to rotate, and the flat gear 16 is used to engage with the flat gear 2 18 to drive the flat gear 2 18 and the inner ring 11 to rotate, and then drive the glass screen to rotate, changing the position of the glass screen. When the inner ring 11 rotates, the guide ring 2 rotates along the arc groove on one side of the vertical plate 15 until the infrared receiver 10 can receive the infrared signal;

[0028] The electric push rod 8 can be used to drive the mounting part and the scanning component 1 to move, adjust the scanning range of the bottom of the scanning component 1 on the glass screen, use the scanning component 1 to scan the glass screen in the vertical direction, and use the scanning component 2 14 to scan the glass screen in the horizontal direction. During scanning, the motor 2 20 drives the bevel gear 1 21 to rotate, and the bevel gear 1 21 drives the bevel gear 2 22 to rotate. The mounting part and the scanning component 2 14 rotate on the top of the auxiliary block 19, so that the scanning component 2 14 can fully scan the top of the glass screen. Among them, the scanning component 1 can detect defects that may exist in the vertical direction, such as inconsistent height of components, shadows in the vertical direction, etc. The scanning component 2 14 is more effective in detecting defects in the horizontal direction, such as scratches and stains.
