[0036] In this embodiment, a limiting groove is provided at the middle of the top of the frame 1, and a sliding sleeve rod 11 is fixedly connected to the inside of the limiting groove. A guide block 12 is sleeved on the outside of the sliding sleeve rod 11. The top of the guide block 12 is connected to the bottom of the No. 2 cylinder 13. The guide block 12 is arranged to move horizontally on the sliding sleeve rod 11, and the use position of the fixing component 15 can be adjusted, so it is convenient to fix LCD screens of different sizes, and the applicability is stronger.

[0037] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0038] In actual application, the LCD screen is transported by the conveyor belt 2. If the screen is tilted, the push plate 4 can push the LCD screen on the conveyor belt 2 under the push of the No. 1 cylinder 3, so that it is transported in the middle direction of the conveyor belt 2. When the LCD screen is transported to the bottom of the connecting frame 5, the box 1501 is lowered by the extension and contraction of the No. 2 cylinder 13, and the LCD screen is pressed by the fixed pressure plate 1509 to complete the fixing step. Then the No. 3 cylinder 6 pushes the pressure sensor 7 to descend, and the bending of the LCD panel is detected by the pressure sensing pin 8. The setting of the buffer spring 1508 and the flexible rubber pad can avoid excessive pressure when the fixed pressure plate 1509 contacts the LCD screen. The guide block 12 moves horizontally on the sliding sleeve 11, and the use position of the fixing component 15 can be adjusted, so that it is convenient to fix LCD screens of different sizes, and the applicability is stronger. After the LCD screen completes the bending detection, it continues to be transported with the conveyor belt 2.

The cleaning bristles 902 are made of flexible material, so they are in flexible contact with the surface of the LCD screen, and the LCD screen will not be scratched while sweeping away the dust.

[0039] In summary, with the aid of the above-mentioned technical scheme of the utility model, through the setting of the fixing component, the box body is lowered by the extension and contraction of the No. 2 cylinder, and the LCD screen is pressed by the fixed pressure plate to complete the fixing step. The setting of the buffer spring and the flexible rubber pad can prevent the fixed pressure plate from being damaged by excessive pressure when it contacts the LCD screen. The rotating block can rotate the rotating column, so that a group of elastic fixing elements can be quickly replaced with a different group of elastic fixing elements after being worn out for a period of time. The guide block moves horizontally on the sliding sleeve rod, and the use position of the fixing component can be adjusted, so it is convenient to fix LCD screens of different sizes, and the applicability is stronger. The setting of the cleaning component can quickly clean the dust on the surface of the LCD display that has passed the bending test through the cleaning bristles. The cleaning bristles are made of flexible material, so they are in flexible contact with the surface of the LCD screen, and will not scratch the LCD screen while sweeping away the dust. Under the push of the No. 1 cylinder, the push plate can push the LCD display that is placed crookedly on the conveyor belt to the middle direction of the conveyor belt, so that it is convenient for the subsequent fixing component to fix it.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
