In addition, after the flat-panel screen is clamped and fixed, it is not convenient to adjust the angle of the flat-panel screen, which also makes it inconvenient to detect the flat-panel screen, further affecting the detection efficiency of the flat-panel screen and is not conducive to use.

[0015] A method for using a flat screen positioning fixture comprises the following steps: S1. Place the flat screen to be processed or inspected on the support seat and at the bottom of the pressing block. Control the operation of the first motor to drive the first screw to rotate. The rotation of the first screw drives the pressing wheel to move downward to extrude the trapezoidal block through the cooperation of the first screw sleeve, the connecting block and the sliding sleeve. The turning frames on both sides are turned to the opposite sides through the cooperation of the trapezoidal blocks. The tops of the turning frames on both sides will turn toward the middle. The turning frames drive the pressing block to turn downward and gradually approach the flat screen until it is close to the flat screen, so that the top of the flat screen can be pressed tightly. S2. Controlling the second motor to start can drive the second screw to rotate. The rotation of the second screw can drive the second screw sleeve to move upward. The second screw sleeve drives the lifting shell to move upward through the cooperation of the lifting plate. When the lifting shell moves upward, the positioning rod slides in the inner cavity of the lifting shell, thereby driving the positioning rods on both sides to move toward the middle.

Controlling the lighting lamp to turn on can provide auxiliary lighting for the flat screen. Controlling the third motor to turn on can drive the turntable and the rotating block to rotate. The rotating block will slide in the inner cavity of the adjustment frame, thereby driving the adjustment frame to flip with the second mounting block. The adjustment frame drives the lighting lamp to flip for angle adjustment, and the flat screen can be illuminated at multiple angles, which is convenient for subsequent processing of the flat screen. S4. When the angle of the flat-panel screen needs to be adjusted, only the two pull rings need to be pulled to both sides respectively. The pull rings drive the two pull plates to move away from each other through the cooperation of the pull rod to squeeze the third spring. The pull plates drive the plug rods on both sides to move away from each other and move out of the socket. Then the support seat can be flipped up or down to adjust the angle. After the adjustment, the two pull rings are moved to the middle. The pull rings drive the plug rods on both sides to move to the middle and insert them into the socket through the cooperation of the pull rod and the pull plate. The support seat can be positioned to facilitate adjusting the flat-panel screen to a suitable operating angle.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a clamping mechanism, wherein the pressing unit can press the four corners of the top of the flat screen to improve the stability of the flat screen, and the clamping unit can clamp the two sides of the flat screen to further improve the stability of the flat screen, avoid the flat screen from being offset during processing or testing, and improve the processing efficiency of the flat screen. The present invention provides a lighting mechanism, and can provide auxiliary lighting to the flat screen through the cooperation of the lighting lamp. At the same time, the angle of the lighting lamp can be adjusted, which is convenient for subsequent processing of the flat screen and further improves the processing efficiency of the flat screen. By setting an adjustment component, the present invention can adjust the angle of the flat screen after clamping and fixing the flat screen, so that the flat screen is adjusted to an angle suitable for personnel processing or testing, which facilitates subsequent operations on the flat screen and further improves the processing efficiency of the flat screen.

The pull rings 4008 drive the two pull plates 4005 to move away from each other and squeeze the third spring 4009 through the cooperation of the pull rod 4007. The pull plates 4005 drive the insertion rods 4006 on both sides to move away from each other and move out of the socket 4002. Then, the support seat 11 can be flipped up or down to adjust the angle. After the adjustment is completed, the two pull rings 4008 are moved toward the middle. The pull rings 4008 drive the insertion rods 4006 on both sides to move toward the middle and insert them into the socket 4002 through the cooperation of the pull rod 4007 and the pull plate 4005. The support seat 11 can be positioned, which facilitates the adjustment of the flat screen to a suitable operating angle.

10. A method for using a flat screen positioning fixture, characterized in that: The following steps are involved: S1. A flat screen to be processed or inspected is placed on the support seat (11) and located at the bottom of the pressing block (2104). The first motor (2101) is controlled to operate to drive the first screw (2108) to rotate. The first screw (2108) rotates to drive the pressing wheel (2112) to move downward to extrude the trapezoidal block (2105) through the cooperation of the first screw sleeve (2109), the connecting block (2113) and the sliding sleeve (2111). The turning frames (2102) on both sides are turned to opposite sides through the cooperation of the trapezoidal block (2105). The tops of the turning frames (2102) on both sides are turned toward the middle. The turning frames (2102) drive the pressing block (2104) to turn downward and gradually approach the flat screen until they are tightly attached. The top of the flat screen can be pressed tightly. S2. Controlling the second motor (2202) to start can drive the second screw rod (2203) to rotate. The rotation of the second screw rod (2203) can drive the second screw sleeve (2204) to move upward. The second screw sleeve (2204) drives the lifting shell (2206) to move upward through the cooperation of the lifting plate (2205). When the lifting shell (2206) moves upward, the positioning rod (2208) slides in the inner cavity of the lifting shell (2206), thereby driving the positioning rods (2208) on both sides to move toward the middle. The positioning rod (2208) can drive the clamping plates (2209) on both sides to move toward the middle and gradually approach the flat screen until they are close to each other through the cooperation of the moving block (2207). The two sides of the flat screen can be clamped and fixed, which is convenient for subsequent processing of the flat screen. S3, controlling the illumination lamp (3006) to be turned on to provide auxiliary illumination for the flat screen, controlling the third motor (3002) to be turned on to drive the turntable (3003) and the rotating block (3004) to rotate, and the rotating block (3004) to slide in the inner cavity of the adjustment frame (3005), thereby driving the adjustment frame (3005) to flip with the second mounting block (3007), and the adjustment frame (3005) drives the illumination lamp (3006) to flip for angle adjustment, so that the flat screen can be illuminated at multiple angles, which is convenient for subsequent processing of the flat screen; S4. When the angle of the flat screen needs to be adjusted, the two pull rings (4008) only need to be pulled to the sides respectively. The pull rings (4008) drive the two pull plates (4005) to move away from each other and squeeze the third spring (4009) through the cooperation of the pull rod (4007). The pull plates (4005) drive the plug rods (4006) on both sides to move away from each other and move out of the insertion hole (4002). Then, the support seat (11) can be flipped upward or downward to adjust the angle. After the adjustment is completed, the two pull rings (4008) are moved to the middle. The pull rings (4008) drive the plug rods (4006) on both sides to move to the middle and insert them into the insertion hole (4002) through the cooperation of the pull rod (4007) and the pull plate (4005). The support seat (11) can be positioned, so that the flat screen can be adjusted to a suitable operating angle.
