[0010] The second motor drives the first shaft to rotate through the output shaft, the first shaft drives the first gear roller to rotate, the first gear roller drives the first gear cylinder to slide downward on the first detection housing, the first gear cylinder drives the first fixing member to move downward through the first rotating rod, so that the first flexible pressure strip on the first fixing member is pressed on the edge of the display screen, the first flexible pressure strip is made of flexible material, and is used to prevent the display screen from being embossed by the first fixing member, when the pressure of the first fixing member is too large, the display screen generates a reaction force on the first fixing member, the first fixing member generates a relative displacement with the first detection housing under the action of the reaction force, and the first spring is compressed, and the first spring absorbs and transforms the reaction force through its own compression deformation.

[0015] Furthermore, the second swing blade assembly includes a second rotating rod, which is rotatably mounted on the first fixed member, and a second swing blade plate is mounted on the second rotating rod.

[0020] Furthermore, the exhaust fan assembly includes a connecting ring, which is installed in the negative pressure chamber, and a fourth motor is installed on the connecting ring, and an exhaust fan wheel is installed on the output shaft of the fourth motor.

[0021] While the first detection fixture is being purged, the control system turns on the fourth motor, and the output shaft of the fourth motor drives the exhaust fan wheel to rotate. The exhaust fan wheel rotates and drives the air in the negative pressure chamber to be discharged. After the air in the negative pressure chamber is discharged, negative pressure is generated. The negative pressure chamber sucks the air inside the second fixture through the air intake hose, so that the inside of the second fixture becomes negative pressure and generates suction. The electric valve on the second fixture is opened, and the second fixture sucks the airflow mixed with dust blown out by the first fixture through the dust suction port.

The second fixing part not only has the clamping function, but also has the function of filtering and collecting the dust in the dust collection box.

[0024] 2. The adjustment component is used to drive the first swing blade component to deflect, and the first swing blade component synchronously drives the second swing blade component to deflect through the transmission rack. The first swing blade plate and the second swing blade plate drive the fast-flowing airflow to deflect in the direction of the dust, so that the airflow is concentrated to the dust position, realizing the functions of wind direction adjustment and concentration, achieving the purpose of directional dust sweeping, and improving cleaning efficiency and accuracy. The setting of the tooth column enables the first swing blade component to always maintain meshing transmission with the adjustment component while the first slide bar slides up and down.

[0025] 3. The fan wheel assembly is driven to rotate by the first motor to accelerate the airflow in the boost chamber, and the airflow is introduced into the first fixing part through the air outlet hose, thereby giving the first fixing part the function of cleaning dust. The accelerated gas flows out from the first fixing part and blows away the dust on the surface of the display screen, so that the first fixing part can clean the surface of the display screen while clamping and fixing it.

[0026] 4. The second motor is used to drive the first gear roller to rotate. The first gear roller drives the first fixing part on the first slide bar to press down through the first gear cylinder, so that the first fixing part presses the edge of the display screen. The first fixing part and the second fixing part are pressed down synchronously to press the two sides of the display screen to achieve the effect of fixing the display screen. The flexible pressure strip at the bottom of the fixing part prevents the display screen from being embossed. When the downward pressure of the first fixing part and the second fixing part is too large, the first spring and the second spring are used to convert the excessive pressure into their own deformation, respectively, so as to achieve the purpose of pressure absorption and conversion. When the automated testing equipment generates mechanical vibration, when the vibration is transmitted to the first spring, the vibration will cause the first spring to deform, and then convert and absorb the vibration to achieve the effect of shock absorption.

After that, the first detection fixture 6 and the second detection fixture 7 fix the edges of the display screen on both sides, and the slide drawer 4 drives the display screen into the chassis 1, and the display screen is imaged and inspected by the visual inspection equipment.

[0045] When the visual detection component 2 detects that there is dust attached to the display screen, the output shaft of the first motor 611 drives the fan wheel component 67 to rotate, and the fan wheel component 67 centrifugally throws out the air in the boost chamber 661, and the air enters the first fixing member 68 from the air outlet 662 through the air outlet hose 69; the control system drives the adjustment rack 653 to move through the output shaft of the electric telescopic rod 652, and the adjustment rack 653 drives the gear column 631 to rotate, and the gear column 631 drives the first slide bar 633 to rotate, and the first slide bar 633 drives the first rotating rod 635 to rotate.

[0046] While the first detection fixture 6 is being purged, the control system turns on the fourth motor 741, and the output shaft of the fourth motor 741 drives the exhaust fan wheel 742 to rotate. The exhaust fan wheel 742 rotates and drives the air in the negative pressure chamber to be discharged. After the air in the negative pressure chamber is discharged, negative pressure is generated.
