[0020] Please see Figure 1 A testing device 100 for testing screens includes: a body 10 and a feeding assembly 20, a testing assembly 30, a transfer platform 40, and a film application assembly 50 disposed on the body 10. The feeding component 20 is disposed on one side of the detection component 30. The feeding component 20 is used to place the screen on the detection component 30. The transfer platform 40 is disposed between the film application component 50 and the detection component 30. The transfer platform 40 is used to move the screen on the detection component 30 to the film application component 50.

[0021] The testing equipment 100 is used to test screens. The testing equipment 100 includes a body 10 and a loading assembly 20, a testing assembly 30, a transfer platform 40, and a film application assembly 50, all mounted on the body 10. The body 10 can be a frame structure welded from metal profiles or plates, with a mounting surface on it. The loading assembly 20, testing assembly 30, transfer platform 40, and film application assembly 50 are all mounted on the mounting surface. The loading assembly 20 is located to one side of the testing assembly 30 and is used to place the screen on the testing assembly 30 or in another area. The testing assembly 30 is used to detect the state of the screen and can be a camera-based detector or an ultrasonic detector, etc. The screen protector assembly 50 is positioned on the side opposite to the inspection assembly 30, and the transfer platform 40 is positioned between the screen protector assembly 50 and the inspection assembly 30. Specifically, after the feeding assembly 20 places the screen on the inspection assembly 30 for inspection, screens that pass the inspection are transferred from the inspection assembly 30 to the screen protector assembly 50 by the transfer mechanism 41, while screens with defects are sent to the processing area for processing via the transfer platform 40. After the transfer mechanism 41 sends the screen to the screen protector assembly 50, the screen protector assembly 50 applies a screen protector to protect the screen and prevent damage to the screen after inspection, which would affect the screen's pass rate and production efficiency.

[0022] Please see Figure 2 In some embodiments, the film application assembly 50 includes: a film application component 51 and a film application platform 52; Both the film application platform 52 and the film application component 51 are mounted on the machine body 10. The film application platform 52 is used to support the screen. The film application platform 52 has a first station and a second station. When the film application platform 52 is at the first station, the transfer platform 40 installs the screen on the film application platform 52. When the film application platform 52 is at the second station, the film application component 51 corresponds to the orthographic projection position of the film application platform 52. The film application component 51 is used to apply a film to the screen.

[0023] Understandably, both the film application platform 52 and the film application component 51 are mounted on the machine body 10. The film application platform 52 is used to support the screen, and the film application component 51 is used to cooperate with the film application platform 52 to apply the film. The film application platform 52 has a first station and a second station. When the film application platform 52 is in the first station, the transfer platform 40 mounts the screen onto the film application platform 52. When the film application platform 52 is in the second station, the film application component 51 corresponds to the orthographic projection position of the film application platform 52, and the film application component 51 applies the screen film. Specifically, the film application component 51 is used to precisely adhere the protective film to the screen surface. It can use a vacuum suction cup to pick up the protective film and cover the screen; or it can use a pressure-pressing film application mechanism, through a robotic arm or a cylinder-driven pressure head, to press the protective film onto the screen.

[0024] Understandably, the film application platform 52 is used to support the screen to be applied. Both the first and second stations of the film application platform 52 are preset positions to facilitate precise positioning. Specifically, the first station is the preset position of the film application platform 52 when receiving the screen. At this station, the film application platform 52 is positioned where the screen can be placed on the transfer platform 40, ensuring that the screen can be smoothly and accurately transferred from the transfer platform 40 to the film application platform 52. The second station is the preset position of the film application platform 52 when applying the film. At this station, the film application platform 52 moves the screen to the position corresponding to the film application component 51, so that the film application component 51 can accurately adhere the protective film to the screen surface to achieve film application. This avoids manual intervention in positioning operations, improves the efficiency and accuracy of screen transfer, and enhances the automation level and production efficiency of the testing equipment 100.

[0025] In some embodiments, a positioning mechanism may be provided on the film application platform 52 to ensure that the screen can be accurately placed on the film application platform 52 and that the film can be accurately applied. For example, the alignment of the film application platform 52 and the film application component 51 can be achieved by using a position sensor or an optical alignment system.

[0026] Please see Figure 2 In some embodiments, the film application assembly 50 further includes: a first moving mechanism 53 and a second moving mechanism 54; The first moving mechanism 53 and the second moving mechanism 54 are spaced apart on the machine body 10. The first moving mechanism 53 is connected to the film application platform 52 to drive the film application platform 52 to move between the first station and the second station. The second moving mechanism 54 is connected to the film-applying component 51. The second moving mechanism 54 is used to drive the film-applying component 51 to move so that the film-applying component 51 covers the screen with a protective film.

[0027] Understandably, the film application assembly 50 also includes a first moving mechanism 53 and a second moving mechanism 54. The first moving mechanism 53 and the second moving mechanism 54 are spaced apart on the machine body 10. The first moving mechanism 53 is connected to the film application platform 52 to drive the film application platform 52 to move between a first station and a second station; the second moving mechanism 54 is connected to the film application component 51 and is used to drive the film application component 51 to move; the first moving mechanism 53 drives the film application platform 52 to move between the first station and the second station. It can be driven by a ball screw system driven by a servo motor, thereby driving the film application platform 52 to perform linear reciprocating motion in the horizontal direction; or it can be a pneumatic or hydraulic cylinder, using air pressure or hydraulic pressure to drive the piston rod to extend and retract, achieving rapid positioning of the film application platform 52. The second moving mechanism 54 is responsible for driving the film application component 51 to move in the vertical direction so that the film application component 51 covers the screen with the protective film. For example, the second moving mechanism 54 can be an electric telescopic rod that drives the film applicator 51 to move up and down and applies appropriate pressure when it contacts the screen to achieve film application, thereby improving the automation level, film application accuracy and production efficiency of the film application process, and ensuring the consistency and reliability of film application quality.

[0028] Please see Figure 3 In some embodiments, the detection component 30 includes: a first imaging element 31 and a second imaging element 32; Both the first camera component 31 and the second camera component 32 are disposed on the body 10, wherein the first camera component is used to capture the front of the screen and the second camera component is used to capture the back of the screen.

[0029] Understandably, the detection component 30 is used to detect whether the screen has defects, damage, or other non-compliant conditions. In this embodiment, the detection component 30 detects the screen by image acquisition. The detection component 30 includes a first imaging element 31 and a second imaging element 32; wherein, the first imaging element 31 is used to acquire images of the front of the screen, and the second imaging element 32 is a device for acquiring images of the back of the screen. When the screen is placed in the position corresponding to the first imaging element, the first imaging element captures images of the front of the screen. These images are then transmitted to the image processing unit for analysis to detect defects such as scratches, bright spots, dark spots, foreign objects, and color differences on the front of the screen. When the screen is placed in the position corresponding to the second imaging element, the second imaging element triggers capture to acquire images of the back of the screen. In this way, the surface of the screen can be detected by both the first and second imaging elements, thereby improving the detection efficiency of the screen during the detection process.

[0030] Optionally, the first and second cameras can be industrial cameras, high-resolution cameras, line scan cameras, etc. They are typically equipped with corresponding optical lenses and image sensors to ensure that the acquired images are clear and accurate, meeting the needs of subsequent image processing and defect identification.

[0031] It should be noted that the second camera can be set as a line scan camera, while the first camera can be set as an area scan camera.

[0032] Please see Figure 4 In some embodiments, it also includes: a third moving mechanism 55, a first carrier 56, and a second carrier 57; The third moving mechanism 55 is disposed on the body 10, and the first carrier 56 and the second carrier 57 are disposed at intervals on the third moving mechanism 55; the second shooting component 32 is disposed on the third moving mechanism 55, and the first carrier 56 and the second carrier 57 each have a shooting position. The third moving mechanism 55 drives the first carrier 56 and the second carrier 57 to be positioned at the shooting position so that the second shooting component can shoot the front of the screen.

[0033] Understandably, the detection component 30 also includes a third moving mechanism 55, a first support member 56, and a second support member 57. The third moving mechanism 55 is mounted on the body 10, and the first support member 56 and the second support member 57 are spaced apart on the third moving mechanism 55. The third moving mechanism 55 can be a linear guide module, driven by a lead screw or synchronous belt to achieve high-precision linear reciprocating motion. Both the first support member 56 and the second support member 57 are mounted on the third moving mechanism 55, allowing the third moving mechanism 55 to drive the first support member 56 and the second support member 57 to move. The first support member 56 and the second support member 57 can perform alternating or parallel processing of the screen to improve detection efficiency.

[0034] Understandably, the third moving mechanism 55 is positioned on the moving path of the second shooting member 32 or at one end of the third moving mechanism 55. This way, when the first carrier member 56 and the second carrier member 57 move on the third moving mechanism 55, they can deliver the screen to the second shooting member 32 for shooting. Both the first carrier member 56 and the second carrier member 57 have shooting positions. When the first carrier member 56 and the second carrier member 57 are in the shooting positions, the second shooting member 32 can shoot the screen located on the first carrier member 56 and the second carrier member 57 to detect whether there is damage or defects on the front of the screen.

[0035] Please see Figure 7 In some embodiments, the detection component 30 further includes: a support frame 33 and a supplementary lighting component 34; The support member is disposed on the body 10, and the supplementary light member 34 and the first shooting member 31 are disposed on the body 10 in sequence. The supplementary light member 34 is used to supplement light for the first shooting member 31.

[0036] Understandably, the support frame 33 is mounted on the body 10. The support frame 33 has a support surface for supporting the screen. A supplementary lighting element 34 and a first imaging element 31 are mounted on the support frame 33. Both the supplementary lighting element 34 and the imaging element are positioned below the support surface, with the first imaging element 31 positioned at the bottom. This allows the supplementary lighting element 34 to provide supplementary lighting for the first imaging element 31. When detecting the front of the screen, the supplementary lighting element 34 provides uniform and sufficient light, enabling the first imaging element 31 to capture a clearer and more detailed screen image. Optionally, the supplementary lighting element 34 can be an LED array, a ring light source, a strip light source, etc.

[0037] Please see Figure 7 In some embodiments, it further includes a cleaning component 60; the cleaning component 60 is disposed on the support frame 33 and is used to clean the screen.

[0038] Understandably, the cleaning component 60 is used to remove dust, stains, or other impurities from the screen surface. The cleaning component 60 is mounted on the support frame 33 for secure fixation, and it effectively cleans the screen. Specifically, the cleaning component 60 can be firmly installed on the support frame 33 using bolts, clips, welding, or other methods. The cleaning component 60 is used to clean the screen before the first and second imaging components 31 and 32 take pictures, ensuring the screen surface is clean. Alternatively, it can be used after the first imaging component 31 performs a line scan on the back surface before cleaning, improving the detection accuracy of the first and second imaging components 31 and avoiding misjudgments caused by impurities, thus improving the overall detection quality and product yield of the testing equipment 100.

[0039] Understandably, the cleaning component 60 could be a mechanical brush that removes dust by rubbing the bristles against the screen surface; it could also be an air knife that uses high-speed airflow to sweep the screen surface and remove adhering substances; it could also be a vacuum cleaner that uses negative pressure suction to remove particles from the screen surface; or it could be an electrostatic dust collector that uses electrostatic adsorption to remove tiny particles; or it could be an ultrasonic cleaning head that uses ultrasonic vibration to remove dirt from the screen surface.

[0040] Please see Figure 3 In some embodiments, it also includes: a first conveyor belt 70 and a second conveyor belt 71; The first conveyor belt 70 and the second conveyor belt 71 are disposed on the machine body 10. The first conveyor belt 70 is located between the film application assembly 50 and the third moving mechanism 55, and the second conveyor belt 71 is disposed on the side away from the feeding assembly 20.

[0041] Understandably, the inspection equipment 100 also includes a first conveyor belt 70 and a second conveyor belt 71. Both the first conveyor belt 70 and the second conveyor belt 71 are mounted on the machine body 10. The first conveyor belt 70 is located between the film-applying assembly 50 and the third moving mechanism 55. The first conveyor belt 70 is used to move the screen from a position near the inspection assembly 30 to a position near the film-applying assembly 50, and after film application, it transports the screen to a storage location for storage. The second conveyor belt 71 is located on the side away from the feeding assembly 20. The second conveyor belt 71 is used to transport screens with defects after inspection to a processing location, separating good screens from defective screens, thus enabling the screens to circulate within the inspection equipment 100, thereby ensuring the reliability of screen transport and production efficiency.

[0042] Please see Figure 4 and Figure 5 In some embodiments, the feeding assembly 20 includes: a feeding mechanism 21, a first support 22, and a sweeping mechanism 23; The feeding mechanism 21 and the sweeping mechanism 23 are respectively disposed on two opposite sides of the first bracket 22, and the feeding assembly 20 and the sweeping mechanism 23 can slide on the first bracket 22 along the length direction of the first bracket 22; The feeding mechanism 21 is used to move the screen to the first conveyor belt 70, and the sweeping mechanism 23 is used to move the screen to the support frame 33, the first carrier 56 and / or the second carrier 57.

[0043] Understandably, the loading assembly 20 includes a loading mechanism 21, a first support 22, and a sweeping mechanism 23. The loading mechanism 21 and the sweeping mechanism 23 are respectively disposed on two opposite sides of the first support 22, and can slide along the length of the first support 22. The loading mechanism 21 moves the screen to the first conveyor belt 70, and the sweeping mechanism 23 moves the screen to the support frame 33, and the first carrier 56 and / or the second carrier 57. Specifically, the loading mechanism 21 places the screen from the loading area onto the first conveyor belt 70 so that the screen can enter the subsequent testing or film application process. The sweeping mechanism 23 transports the screen to the support frame 33 for sweeping and cleaning, and can also move the screen onto the first carrier 56 and the second carrier 57. Specifically, the loading mechanism 21 can employ a vacuum suction cup robotic arm to achieve precise gripping and placement of the screen. The first support 22 provides support and guidance for the feeding mechanism 21 and the sweeping mechanism 23. It can be a linear guide rail, which reduces manual intervention and improves the automation level and production efficiency of the entire testing equipment 100.

[0044] Please see Figure 6 In some embodiments, the transfer platform includes: a transfer mechanism 41, a second support 42, and a feeding mechanism 43; The second bracket 42 is disposed on the machine body 10, and the transfer mechanism 41 and the unloading mechanism 43 are disposed on opposite sides of the transfer bracket. The transfer mechanism 41 is used to move the screen on the first carrier 56 and / or the second carrier 57 to the film application platform 52.

[0045] Understandably, the transfer platform includes a transfer mechanism 41, a second support 42, and a feeding mechanism 43. The second support 42 is mounted on the machine body 10, and the transfer mechanism 41 and the feeding mechanism 43 are located on opposite sides of the second support 42. The transfer mechanism 41 is used to move the screens on the first carrier 56 and / or the second carrier 57 to the film-applying platform 52. The transfer mechanism 41 is used to transport the screens on the first carrier 56 and / or the second carrier 57 to the film-applying platform 52, so that the film-applying component 51 can apply film to the screens on the film-applying platform 52. The feeding mechanism 43 is used to transport screens that have completed inspection but do not meet the requirements. The feeding mechanism 43 can transport the non-compliant screens to the second conveyor belt, which then transports the screens to the processing area for further processing.

[0046] Understandably, both the transfer mechanism 41 and the unloading mechanism 43 are used to grip the screen with suction cups or clamps. They can use suction cups in conjunction with pneumatic or electric push rods to move the screen onto the film application platform 52 or the second conveyor belt, thus avoiding errors and inefficiencies that may result from manual operation. This improves overall production efficiency and product quality.

[0047] The following example will provide a more detailed explanation of the above technical solution: On a screen production line, finished screens need to undergo visual inspection and have protective films applied to ensure product quality and prevent secondary damage during subsequent transportation. Traditional inspection and film application processes typically involve multiple manual handling operations and long-distance transfers between different devices, which is not only inefficient but also increases the risk of screen damage during transport.

[0048] In this invention, the screen to be tested is placed in an area that the loading assembly 20 can receive. The loading mechanism 21 places the screen on the first conveyor belt 70. Then, the scanning mechanism 23 picks up the screen from the first conveyor belt and places it on the support frame 33. The first imaging element 31 under the support frame 33 scans the back of the screen to obtain an image of the back of the screen. After the first imaging element 31 takes the picture, the cleaning element 60 performs ultrasonic cleaning on the screen. After cleaning, the scanning mechanism 23 transports the screen to the first carrier 56 or the second carrier 57. The first carrier 56 and the second carrier 57 move to the position of the second imaging element 32. The second imaging element 32 takes a picture of the front of the screen to obtain a high-resolution front image. After taking the picture, the screen is moved to the film application platform 52 by the transfer mechanism 41. Then, the film application platform 52 moves and moves the screen to the position corresponding to the film application element 51 to complete the film application. After the film application is completed, the unloading mechanism 43 places the screen back on the first conveyor belt. In this way, the screen testing and film application are completed. If the screen fails to meet the requirements after inspection by the inspection component 30, the unloading mechanism 43 moves the screen to the second conveyor belt and transports it to the defective product processing area to process the defective product. This allows the entire process of screen loading, inspection, cleaning, transfer, film application, and unloading to be completed continuously on one machine body 10, reducing manual handling and long-distance transmission of the screen between different devices, thereby effectively avoiding the risk of secondary damage to the screen during transportation in the traditional process.
