After the main conveying belt is damaged, the flexible screen can be tested by switching to the spare conveying belt.

[0015] The present invention provides a cleaning brush. When the suction cup moves horizontally along the track toward one side of the main conveying belt, the sucked flexible screen will contact the upper end of the cleaning brush. The cleaning brush will clean the bottom of the flexible screen to prevent dust from sticking to the bottom of the flexible screen and affecting the judgment of the detection camera. The flexible screen cleaned by the cleaning brush is finally placed on the extrusion fixing part of the main conveying belt.

[0016] By setting a self-recovering airbag, when the extrusion fixing member on which the flexible screen is placed moves toward the driving member, the extrusion frame of the extrusion fixing member will contact the extrusion self-recovering airbag, and the two lower ends of the extrusion frame can be extended and retracted, thereby adjusting the height of the upper end of the extrusion frame. After being squeezed, the self-recovering airbag will release the internal gas, and part of the gas will rush out from the first air outlet groove to form a first flushing airflow. After the first flushing airflow rushes out from the first air outlet groove, it flows toward the bottom of the brush and the detection camera. The first flushing airflow is used to flush the brush to make the dust on the brush fall off, thereby preventing the brush from being incompletely cleaned due to dust adsorbed on the brush during subsequent cleaning of the detection camera, thereby affecting the judgment of the detection camera. At the same time, the first flushing airflow is used to blow away the dust at the bottom of the detection camera and cool the bottom of the detection camera, thereby preventing the detection camera from being adsorbed with dust at the bottom of the detection camera during long-term use, thereby reducing the heat dissipation function of the detection camera, thereby detecting high temperature inside the detection camera, and reducing the service life of the detection camera.

[0017] By setting up a self-recovering airbag, after the extrusion frame squeezes the self-recovering airbag, another part of the gas rushes out from the second air outlet groove to form a second flushing airflow. After the second flushing airflow rushes out from the second air outlet groove, it is used to flush the top of the flexible screen to prevent dust from sticking to the top of the flexible screen, thereby affecting the judgment of the detection camera.

[0018] By setting up a cleaning piece, during the detection of the detection camera, if a foreign object is found, the cleaning piece will be started, which will cause the moving rod to move back and forth in the sliding groove, so that the brush can clean the bottom of the detection camera, to prevent the lens of the detection camera from absorbing dust, thereby causing misjudgment of the detection device; when the brush cleans the lens at the bottom of the detection camera back and forth, dust will fall off, and the dust box will collect the fallen dust, to prevent the dust from falling onto the flexible screen below, thereby causing misjudgment of the detection device.

[0019] By setting a knocking rod, when the extrusion frame of the extrusion fixing part approaches the knocking rod, the knocking rod will be pushed to flip toward the side of the cleaning part, and the rotating rod will rotate along with the knocking rod, and the rotation of the rotating rod drives the toggle rod to operate. Finally, the knocking rod will enter the curved part under the push of the extrusion frame, and the knocking rod will squeeze the rubber rod in the curved part, and the rubber rod will bend to accumulate elastic potential energy. At this time, the toggle rod will flip along with the knocking rod, so that the toggle rod can toggle the cleaning brush, thereby causing the dust adsorbed by the cleaning brush to fall off, thereby preventing the cleaning brush from being adsorbed with dust on the top of the cleaning brush after long-term use, thereby failing to clean the top of the flexible screen. After the knocking rod is separated from the extrusion frame, the rotating rod will quickly return to its original state under the action of the torsion spring and the rubber rod, and the knocking rod will knock the subsequent extrusion frame when it recovers, thereby causing the dust in the extrusion fixing part to fall off, thereby preventing the dust from being adsorbed on the extrusion fixing part, thereby reducing the misjudgment of the detection camera during detection.

[0020] The present invention has a simple structure and can well detect the flexible screen to prevent the flexible screen and the clamp from absorbing foreign matter, thereby causing misjudgment of the detection device. It can also prevent the detection camera from being attached with foreign matter, thereby causing misjudgment of the detection device. During the detection, the detection camera can also be dusted and cooled, thereby extending the service life of the detection camera. BRIEF DESCRIPTION OF THE DRAWINGS

Multiple recovery support frames 71 are fixedly installed on the other side of the top of the support platform 12, the recovery belt member 72 is installed on the top of the multiple recovery support frames 71, the recovery fixing rod 73 is fixedly installed at the top center of the support platform 12, the recovery horizontal slide rail 74 is installed on the upper end side wall of the recovery fixing rod 73, the recovery suction cup 76 is installed on the lower end bottom of the sliding rod 75, and the rubber rod 83 is installed in the bending part 810.

[0045] During use: 1. Place the flexible screen to be inspected on the screen placement platform 22, start the detection device, and the suction cup horizontal moving track 23 moves toward one side of the screen placement platform 22. After the suction cup support rod 24 moves to the top of the flexible screen, the suction cup horizontal moving track 23 stops, and the suction cup member 25 telescopes and moves downward to absorb the flexible screen. The suction cup member 25 moves upward after absorbing the flexible screen, and the suction cup horizontal moving track 23 moves toward one side of the main conveying belt 34. When the suction cup horizontal moving track 23 moves toward one side of the main conveying belt 34, the sucked flexible screen will contact the upper end of the cleaning brush 82, and the cleaning brush 82 will clean the bottom of the flexible screen to prevent dust from sticking to the bottom of the flexible screen and affecting the judgment of the detection camera 431. The flexible screen cleaned by the cleaning brush 82 is finally placed on the extrusion fixing member 36 of the main conveying belt 34.

[0046] 2. After the flexible screen is placed on the extrusion fixing member 36 of the main conveying belt 34, the driving member 33 is started, the main conveying belt 34 and the spare conveying belt 35 are operated, and the main conveying belt 34 and the spare conveying belt 35 drive the driven member 32 to operate, and the extrusion fixing member 36 follows the operation of the main conveying belt 34, and the extrusion fixing member 36 on which the flexible screen is placed moves toward the driving member 33. When the extrusion fixing member 36 on which the flexible screen is placed moves toward the driving member 33, the extrusion frame 364 of the extrusion fixing member 36 will contact and extrude the self-restoring airbag 63, and the two lower ends of the extrusion frame 364 can be extended and retracted, thereby adjusting the height of the upper end of the extrusion frame 364. After being squeezed, the self-restoring airbag 63 will release the internal gas, and part of the gas will rush out from the first air outlet groove 630 to form a first flushing airflow, and the first flushing airflow will be formed. After a flushing airflow rushes out from the first air outlet groove 630, it flows toward the brush 522 and the bottom of the detection camera 431. The first flushing airflow is used to flush the brush 522, so that the dust on the brush 522 falls off, preventing the brush 522 from being absorbed by the dust when cleaning the detection camera 431 later, causing the detection camera 431 to be not thoroughly cleaned, thereby affecting the judgment of the detection camera 431. At the same time, the first flushing airflow is used to blow away the dust at the bottom of the detection camera 431 and cool the bottom of the detection camera 431, to prevent the detection camera 431 from being absorbed by dust at the bottom of the detection camera 431 during long-term use, thereby reducing the heat dissipation function of the detection camera 431, and then the internal temperature of the detection camera 431 is high, reducing the service life of the detection camera 431.

[0047] 3. After the extrusion frame 364 squeezes the self-recovering airbag 63, another part of the gas rushes out from the second air outlet groove 631 to form a second flushing airflow. After the second flushing airflow rushes out from the second air outlet groove 631, it is used to flush the top of the flexible screen to prevent dust from sticking to the top of the flexible screen, thereby affecting the judgment of the detection camera 431.

[0048] 4. During the detection of the detection camera 431, if foreign matter is found, the cleaning member 52 is activated, and the movable rod 520 is moved back and forth in the sliding groove 512, so that the brush 522 can clean the bottom of the detection camera 431 to prevent the lens of the detection camera 431 from being adsorbed with dust, thereby causing misjudgment of the detection device. When the brush 522 cleans the bottom lens of the detection camera 431 back and forth, dust falls, and the dust box 524 collects the fallen dust to prevent the dust from falling onto the flexible screen below, thereby causing misjudgment of the detection device.

[0049] 5. The extrusion fixing member 36 located below the main conveyor belt 34 and the extrusion frame 364 of the extrusion fixing member 36 will push the knocking rod 92 to flip toward the cleaning member 80 when it is close to the knocking rod 92, and the rotating rod 90 rotates along with the knocking rod 92, and the rotation of the rotating rod 90 drives the toggle rod 91 to operate. Finally, the knocking rod 92 will enter the curved portion 810 under the push of the extrusion frame 364, and the knocking rod 92 squeezes the rubber rod 83 in the curved portion 810. The rubber rod 83 bends to accumulate elastic potential energy. At this time, the toggle rod 91 will flip along with the knocking rod 92, so that the toggle rod 91 can toggle the cleaning brush 82, thereby making In order to prevent the dust adsorbed by the cleaning brush 82 from falling off, and to prevent the top of the cleaning brush 82 from being adsorbed with dust after long-term use, so that the top of the flexible screen cannot be cleaned, after the knocking rod 92 is separated from the extrusion frame 364, the rotating rod 90 will bend under the action of the torsion spring and the rubber rod 83, and the elastic potential energy accumulated by the rubber rod 83 will be converted into kinetic energy of the knocking rod 92, so that the knocking rod 92 can quickly return to its original state, and the knocking rod 92 will knock the subsequent extrusion frame 364 when it recovers, so that the dust in the extrusion fixing part 36 falls off, and the dust adsorbed on the extrusion fixing part 36 is prevented, thereby reducing the misjudgment of the detection camera 431 during detection.

[0050] 6. During the inspection, if the inspection is found to be unqualified, the recovery horizontal slide rail 74 will move toward the main conveying belt 34, and the recovery suction cup 76 will be used to absorb the unqualified flexible screen. The recovery suction cup 76 will place the unqualified flexible screen in the recovery belt part 72, and then it will be transported to the unqualified area for recycling through the recovery belt part 72.

[0051] The present invention is provided with a cleaning brush 82. When the suction cup horizontal moving track 23 moves toward one side of the main conveying belt 34, the sucked flexible screen will contact the upper end of the cleaning brush 82. The cleaning brush 82 will clean the bottom of the flexible screen to prevent dust from sticking to the bottom of the flexible screen and thus affecting the judgment of the detection camera 431. The flexible screen cleaned by the cleaning brush 82 is finally placed on the extrusion fixing part 36 of the main conveying belt 34.

[0052] By setting the self-restoring airbag 63, when the extrusion fixing member 36 for placing the flexible screen moves toward the driving member 33, the extrusion frame 364 of the extrusion fixing member 36 will contact and extrude the self-restoring airbag 63, and the two lower ends of the extrusion frame 364 can be extended and retracted, thereby adjusting the height of the upper end of the extrusion frame 364. After being squeezed, the self-restoring airbag 63 will release the internal gas, and part of the gas will rush out from the first air outlet groove 630 to form a first flushing airflow. After rushing out from the first air outlet groove 630, the first flushing airflow flows toward the bottom of the brush 522 and the detection camera 431. The first flushing airflow is used to flush the brush 522. This allows the dust on the brush 522 to fall off, preventing the brush 522 from causing incomplete cleaning of the detection camera 431 during subsequent cleaning of the detection camera 431 due to the dust adsorbed on the brush 522, thereby affecting the judgment of the detection camera 431. At the same time, the first flushing airflow is used to blow away the dust at the bottom of the detection camera 431 and cool the bottom of the detection camera 431, preventing the bottom of the detection camera 431 from being adsorbed with dust during long-term use, thereby reducing the heat dissipation function of the detection camera 431, and thereby causing high temperature inside the detection camera 431, thereby reducing the service life of the detection camera 431.

[0053] By setting up the self-recovering airbag 63, after the extrusion frame 364 squeezes the self-recovering airbag 63, another part of the gas rushes out from the second air outlet groove 631 to form a second flushing airflow. After the second flushing airflow rushes out from the second air outlet groove 631, it is used to flush the top of the flexible screen to prevent dust from sticking to the top of the flexible screen, thereby affecting the judgment of the detection camera 431.

[0054] By setting up the cleaning piece 52, during the detection of the detection camera 431, if a foreign object is found, the cleaning piece 52 is started, and the moving rod 520 will move back and forth in the sliding groove 512, so that the brush 522 can clean the bottom of the detection camera 431, to prevent the lens of the detection camera 431 from being adsorbed with dust, thereby causing misjudgment of the detection device; when the brush 522 cleans the bottom lens of the detection camera 431 back and forth, dust will fall off, and the dust box 524 will collect the fallen dust to prevent the dust from falling onto the flexible screen below, thereby causing misjudgment of the detection device.

[0055] By setting the knocking rod 92, when the extrusion frame 364 of the extrusion fixing member 36 is close to the knocking rod 92, the knocking rod 92 will be pushed to flip toward the cleaning member 80, and the rotating rod 90 will rotate along with the knocking rod 92, and the rotation of the rotating rod 90 drives the toggle rod 91 to operate. Finally, the knocking rod 92 will enter the curved portion 810 under the push of the extrusion frame 364, and the knocking rod 92 will squeeze the rubber rod 83 in the curved portion 810. The rubber rod 83 bends to accumulate elastic potential energy. At this time, the toggle rod 91 will flip along with the knocking rod 92, so that the toggle rod 91 can toggle the cleaning member 80. The sweeping brush 82 causes the dust adsorbed by the sweeping brush 82 to fall off, thereby preventing the sweeping brush 82 from being adsorbed with dust on the top of the sweeping brush 82 after long-term use, thereby preventing the top of the flexible screen from being unable to clean. After the knocking rod 92 is separated from the extrusion frame 364, the rotating rod 90 will, under the action of the torsion spring and the rubber rod 83, cause the knocking rod 92 to quickly return to its original state, and the knocking rod 92 will knock on the subsequent extrusion frame 364 when it is restored, causing the dust in the extrusion fixing part 36 to fall off, thereby preventing the extrusion fixing part 36 from being adsorbed with dust, thereby reducing the misjudgment of the detection camera 431 during detection.

[0056] The present invention has a simple structure and can well detect the flexible screen to prevent the flexible screen and the clamp from absorbing foreign matter, thereby causing misjudgment of the detection device. It can also prevent the detection camera 431 from being attached with foreign matter, thereby causing misjudgment of the detection device. During the detection, the detection camera 431 can also be dusted and cooled, thereby extending the service life of the detection camera 431.

[0057] All possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-mentioned embodiments only express several embodiments of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
