Compared to existing technologies, this screen inspection device features a first inspection mechanism 3 that inspects the top surface of the screen, a rotating mechanism 4 that rotates, and a second inspection mechanism 5 that can inspect the screen from multiple angles. This screen inspection device provides comprehensive inspection of the screen, improving inspection efficiency, reducing manual labor, and increasing yield. Furthermore, the fixture 41 and the rotating shaft 42 are detachably connected, facilitating the replacement of the fixture 41 by operators and enhancing the versatility of the screen inspection device.

[0054] Optionally, the feeding mechanism 2 includes a first conveying assembly 21 and a carrier 22. The first conveying assembly 21 is disposed on the frame 1, and the carrier 22 is disposed on the first conveying assembly 21. The first conveying assembly 21 can drive the carrier 22 to move, and the carrier 22 is detachably connected to the screen. Specifically, the first conveying assembly 21 includes two conveyor belt assemblies, two mounting plates, and several bidirectional lead screws. The two conveyor belt assemblies are spaced apart and slidably disposed on the frame 1 along a second direction, and the conveyor belt assemblies extend along a first direction. The several bidirectional lead screws are spaced apart and slidably disposed on the frame 1 along the first direction, and the two ends of the bidirectional lead screws are respectively threadedly connected to the two mounting plates. The two conveyor belt assemblies are respectively disposed on the two mounting plates. By rotating the bidirectional lead screws, the two mounting plates can be moved closer or further apart, thereby controlling the spacing between the two conveyor belt assemblies. This allows for adaptation to screens of different sizes and improves the versatility of the screen detection device.

[0055] Furthermore, the conveyor belt assembly includes a drive pulley, a driven pulley, a timing belt, and a drive component. The drive pulley and driven pulley are rotatably connected to both ends of the mounting plate, respectively. The timing belt is wound around the outer periphery of the drive pulley and driven pulley.

Further still, the conveyor belt assembly also includes a tensioning pulley, which is rotatably connected to the mounting plate. The tensioning pulley can tension the timing belt and prevent it from slack.

[0056] Optionally, the screen detection device further includes a first light source 14, which is mounted on the frame 1. The first detection component 32 includes a plurality of first cameras 321 and a plurality of second cameras 322.

[0057] Furthermore, the first inspection mechanism 3 also includes a transfer assembly 323, which is slidably mounted on the first support 31 along the second direction. A plurality of second cameras 322 are spaced apart and mounted on the transfer assembly 323. Specifically, the inspection system issues a command to activate the visual IC surface inspection screen. The second cameras 322 perform 3D imaging inspection of the screen, and the first camera 321 performs 2D planar color camera inspection of the screen. The screen is inspected according to the software-set parameters. After inspection, a pass or fail signal is sent to the system. When the system receives a pass signal, it outputs whether the screen assembly is qualified based on the system inspection data. After inspection, a pass signal is returned, and the inspection system is reset. Furthermore, the transfer assembly 323 is a transmission chain structure.

[0058] Optionally, the screen detection device further includes a lifting mechanism 6, which includes a third support 81 and a second conveying component 62. The third support 81 is mounted on the frame 1, and the second conveying component 62 is slidably connected to the third support 81 in a vertical direction.

Specifically, the lifting mechanism 6 also includes a positioning plate, which is disposed on the third support 81. The positioning plate can position the carrier 22. After 3D detection, the carrier 22 and the screen are positioned and fixed by the positioning plate, which facilitates the separation of the carrier 22 and the screen. Further, the second conveying component 62 has the same structure as the first conveying component 21, which will not be described in detail here.

[0059] Optionally, the screen detection device further includes a return mechanism 15, which includes a mounting frame and a return conveying assembly. The mounting frame is fixed to the frame 1, and the return conveying assembly is mounted on the mounting frame. The frame 1 is vertically spaced with an inlet 101 and an outlet 102. The inlet 101 is connected to the first conveying assembly 21 and can convey the carrier 22 to the first conveying assembly 21. The outlet 102 is connected to the return conveying assembly and can convey the carrier 22 to the outlet 102. Furthermore, the structure and function of the return conveying assembly are the same as those of the first conveying assembly 21, and will not be described again here.

[0060] Optionally, the second detection mechanism 5 includes a high-definition color camera and a second light source 521. Both the high-definition color camera and the second light source 521 are mounted on the frame 1 and located above the lifting mechanism 6. The second light source 521 provides a visual light source for the high-definition color camera, which is used to detect the flipped screen. The flipping mechanism 4 also includes a sixth bracket 43, a third movable plate 44, and a fourth movable plate 45. The sixth bracket 43 is mounted on the frame 1. The third movable plate 44 is slidably disposed on the sixth bracket 43 along a first direction. The fourth movable plate 45 is slidably disposed on the third movable plate 44 along a vertical direction. The rotating shaft 42 is rotatably connected to the fourth movable plate 45. Specifically, after the carrier 22 carrying the screen separates from the screen, the rotating shaft 42 rotates downwards by 180°, the clamp 41 holds the screen, the fourth moving plate 45 drives the clamp 41 to rise to a certain height, and then the rotating shaft 42 flips the screen. The third moving plate 44 transfers the screen to the high-definition color camera detection position, and visual inspection is started. After inspection by the 20-megapixel high-definition color vision camera, the product is inspected according to the parameters set by the software. After the inspection is completed, a pass or fail signal is sent to the system. When the system receives the pass signal, it resets after the moving component 7 transfers the screen out of the material.

[0061] Optionally, the screen detection device further includes a moving component 7 and a third detection mechanism 8. Both the moving component 7 and the third detection mechanism 8 are mounted on the frame 1.

Specifically, the third detection mechanism 8 also includes a lifting cylinder 84 and a clamping component 85. The lifting cylinder 84 is mounted on the third bracket 81, and the output end of the lifting cylinder 84 is connected to the support plate 82. The lifting cylinder 84 can drive the support plate 82 to move in the vertical direction. The clamping component 85 is rotatably disposed on the support plate 82 and is used to clamp the screen. Furthermore, several third detection components 83 are divided into two groups, respectively set on the outer sides of two adjacent sides of the clamping component 85. The third detection component 83 is a 2D line scan camera. After the screen is transferred to the position by the previous process, it is driven by the lifting cylinder 84. After the support plate 82 is lowered to a certain height, the 2D line scan camera detects the high-precision dimensional gap between the IC surface of the screen and the light board. After the detection of the two sides is completed, the clamping component 85 rotates 180 degrees, and the 2D line scan camera detects the high-precision dimensional gap between the IC surface of the other two sides of the screen and the light board. The vision is activated, and the vision performs detection on the product according to the parameters set by the software. After the detection is completed, a pass or fail signal is sent to the system. When the system receives the pass signal, the lifting module 123 resets and rises, and the clamping component 85 resets at the same time.

[0062] Furthermore, the moving component 7 includes a fourth support 71, a first moving plate 72, a second moving plate 73, and several suction cups 74. The fourth support 71 is mounted on the frame 1. The first moving plate 72 is slidably disposed on the fourth support 71 in a vertical direction. The second moving plate 73 is slidably disposed on the first moving plate 72 in a first direction. Several suction cups 74 are spaced apart from the second moving plate 73. The suction cups 74 are used to adsorb the screen. Specifically, the third detection mechanism 8 also includes a pressure sensor, which can detect the suction force of the suction cups 74 on the screen to avoid excessive suction force. After the screen has been inspected by the 20-megapixel color camera and the 2D line scan camera, it is adsorbed by the anti-static suction cups 74 and the pressure device is checked to confirm that the adsorption is complete. The first moving plate 72 rises, and the second moving plate 73 moves the screen to the next station, realizing the transfer and detection of the lamp panel surface.

[0063] Optionally, the screen detection device further includes a fourth detection mechanism 9. The fourth detection mechanism 9 includes a fifth bracket 91, a first pusher 92, a second pusher 93, a first baffle 94, and a second baffle 95. The fifth bracket 91 is mounted on the frame 1. The first baffle 94 is disposed at one end of the fifth bracket 91 and extends along a first direction. The first pusher 92 is slidably disposed at the other end of the fifth bracket 91 and can push the screen to abut against the first baffle 94. The second baffle 95 is disposed on one side of the fifth bracket 91 and extends along a second direction. The second pusher 93 is slidably disposed on the other side of the fifth bracket 91 and can push the screen to abut against the second baffle 95. The vertical direction, the first direction, and the second direction are all perpendicular to each other. Specifically, the fourth inspection mechanism 9 also includes a first ranging mechanism and a second ranging mechanism, both of which are mounted on the frame 1. When the screen enters the inspection station and the photoelectric sensor detects a product signal, the first baffle 94 moves to a designated position. The first pusher 92, carrying the first baffle 94, presses it against the screen, aligning it with the screen. The first ranging mechanism is then activated to precisely measure the length and width of the lamp surface PCB board and inspect the product according to the software-set parameters. After inspection, a pass or fail signal is sent to the system. When the system receives a pass signal, it sends it to the second board receiving mechanism 12. When the system receives a fail signal, it sends it to the first board receiving mechanism 11. Furthermore, both the first pusher 92 and the second pusher 93 are cylinders.

[0064] Optionally, the screen inspection device further includes a robotic arm 10 and a first receiving mechanism 11. The robotic arm 10 is mounted on the frame 1 and is used to grasp screens on the fifth support 91. The robotic arm 10 can also move screens that fail inspection to the first receiving mechanism 11, which is used to collect the non-conforming screens. Specifically, the robotic arm 10 is a four-axis picking robotic arm 10, and the first receiving mechanism 11 includes a synchronous belt conveyor assembly. When a product is found to be non-conforming by the size inspection system, the four-axis picking robotic arm 10 picks up the non-conforming screen and moves it to the synchronous belt conveyor assembly, completing the placement of the non-conforming screen. After the photoelectric sensor receives a signal, it starts the synchronous belt conveyor assembly to move down one section of the placement position. When more than seven boards are stored, the photoelectric sensor receives a signal to notify the receiving personnel to collect the boards uniformly, confirm the defect classification data of the products in the system, and continue to start the next round of board collection. Furthermore, the synchronous belt conveyor assembly includes a first synchronous component 111, a second synchronous component 112, and an adjusting component 113. The first synchronous component 111 is fixed to the frame 1, and the second synchronous component 112 is slidably disposed on the frame 1 at intervals from the first synchronous component 111. The adjusting component 113 is used to adjust the distance between the second synchronous component 112 and the first synchronous component 111, making it suitable for screens of different sizes and improving the versatility of the device.

[0065] Optionally, the screen inspection device further includes a second receiving mechanism 12, which is used to collect qualified screens, and the robot arm 10 can move the qualified screens to the second receiving mechanism 12.

[0066] Furthermore, the second receiving mechanism 12 includes a feeding station 121 and a discharging station 122. The empty foam box 13 is disposed at the feeding station 121. The robot arm 10 can move the empty foam box 13 to the discharging station 122, and the robot arm 10 can move the screen that has passed inspection to the empty foam box 13 at the discharging station 122. The discharging station 122 can send out the full foam box 13 containing the screen. The second receiving mechanism 12 also includes a lifting module 123. The lifting module 123 is used to raise the empty foam box 13 at the feeding station 121 by the height of an empty foam box 13, and the lifting module 123 is also used to lower the full foam box 13 at the discharging station 122 by the height of a full foam box 13. Specifically, after the screens pass the inspection of the preceding equipment, the robotic arm 10 picks up the plates and transfers the products to the right-side empty foam feeding box. After three plates are filled, the full foam box 13 lifting module 123 descends by one foam height position. The robotic arm 10 picks up a new empty foam box 13 and places it at the plate placement station. The empty foam box 13 lifting module 123 rises by one foam height position. When 20 layers of foam are filled, the full foam box 13 conveyor belt automatically discharges the foam box 13. The full product is then manually removed. The empty foam box 13 is automatically fed into the empty foam box 13. This process is repeated to achieve automatic loading and unloading of qualified plates.
