[0016] (III) Beneficial effects

[0017] 1. By inserting the plug on the test mainboard into the slot on the display driver body, the test mainboard and the display driver body are electrically connected. The test mainboard will send a series of preset test signals to the display driver body to detect the electrical performance of the display driver body. The detected data is displayed on the display screen for the convenience of observation or recording by the tester. After the display driver body is detected, the test mainboard is separated from the display driver body by the separation component, and the display driver body is pushed out of the limit frame and finally discharged from the discharge port to complete the discharge. The detection device of the display driver is highly automated from conveying, detection to discharge, which greatly reduces manual intervention, improves production efficiency, reduces labor costs and labor intensity, and performs electrical performance detection through preset test signals, which can accurately evaluate the performance of the display driver body and ensure the stability and reliability of product quality.

[0018] Second: the movement of the extension plate drives the push plate to move, and the display driver body on the conveyor belt is pushed from the feed port to the limit frame through the movement of the push plate. After the display driver body in the limit frame is detected, the display driver body is discharged from the discharge port. The above operation is repeated to continuously and sequentially convey the display driver body on the conveyor belt, thereby realizing continuous conveyance of the display driver body on the conveyor belt and improving the detection efficiency. Through the coordinated action of the conveyor belt rolling and the partition plate, it is ensured that the display driver body can accurately enter the detection area from the feed port, thereby improving the accuracy and reliability of the conveyance, ensuring the precise connection between the test main board and the display driver body, and ensuring the stable detection of the display driver body.

[0019] 3. The continued movement of the push plate will exert a thrust on the display driver body, so that the display driver body moves along the length direction of the side baffle plate, so that the display driver body is separated from the discharge port and discharged from the discharge port under the action of its own gravity. In the process of pushing the display driver body to discharge, the display driver body is blocked by the inner walls on both sides of the limit frame and the push plate, so that the display driver body can be accurately discharged from the discharge port, so that the display driver body is pushed between the two side baffles, so that the display driver body can accurately fall from the discharge port, and accurate discharge is completed, thereby realizing the automatic separation and accurate discharge of the test mainboard and the display driver body, reducing manual operations and improving production efficiency.

[0020] 4: After the display driver body is unloaded, the push plate, fixing rod, contact block and stop block are reset, ensuring that the contact block can accurately apply force to the push block, thereby ensuring that the test main board and the plug are reset to the initial state. In the initial state, the test main board and the plug are inserted into the insertion port, and the stop block is located at the discharge port, which is used to limit the side end of the display driver body. In conjunction with the limit of the three side walls of the limit frame and the limit of the push plate, comprehensive limit is achieved on the four sides and the upper and lower ends of the display driver body, so that the display driver body can accurately reach the limit frame, and the plug can be accurately inserted into the slot on the display driver body to complete reliable and accurate electrical connection, thereby ensuring stable detection of the display driver body.

[0021] Five: Through the movement of the through rod one through the fixed rod and the stopper, the movement of the fixed rod, the push plate and the stopper is limited. Through the movement of the through rod two through the extension plate, the movement of the push plate is limited, ensuring its stable movement, avoiding position displacement, and ensuring the stability and rationality of the structural design.

[0034] Working principle:

[0035] In the first step, a plurality of display driver bodies 93 are orderly placed between every two partition plates 92, and the slot 94 is started, so that the conveyor belt 91 rolls to convey the display driver body 93, and the display driver body 93 is conveyed into the limit frame 2 in sequence by the push plate 8, and the plug 31 on the test main board 3 is inserted into the slot 94 on the display driver body 93 to realize the electrical connection between the test main board 3 and the display driver body 93. The test main board 3 will send a series of preset test signals to the display driver body 93 to realize the electrical performance detection of the display driver body 93, and the detected data will be displayed on the display screen 13. The display is displayed to facilitate the observation or recording of the test personnel. After the display driver body 93 is tested, the test motherboard 3 is separated from the display driver body 93 by the separation component, and the display driver body 93 is pushed out of the limit frame 2, and finally discharged from the unloading port 11 to complete the unloading. The detection device of the display driver realizes a high degree of automation from conveying, detection to unloading, greatly reduces manual intervention, improves production efficiency, reduces labor costs and labor intensity, and performs electrical performance testing through preset test signals, which can accurately evaluate the performance of the display driver body 93 and ensure the stability and reliability of product quality;

[0036] In the second step, when the display driver body 93 on the conveyor belt 91 needs to be conveyed into the limit frame 2, the slot 94 is started to make the conveyor belt 91 roll, and the display driver body 93 is conveyed by the rolling of the conveyor belt 91, so that the gap between the two partition plates 92 is aligned with the port of the feed port 22, and then the servo motor 27 is started to rotate the screw rod 271, and the extension plate 81 is driven to move by the rotation of the screw rod 271, and the push plate 8 is driven to move by the movement of the extension plate 81, and the display driver body 93 on the conveyor belt 91 is pushed from the feed port 22 to the limit frame 2 by the movement of the push plate 8, and the limit frame is waited for. After the display driver body 93 in the test board 2 is detected, the display driver body 93 is discharged from the discharge port 11, and the above operation is repeated to continuously and sequentially convey the display driver body 93 on the conveyor belt 91, thereby realizing continuous conveyance of the display driver body 93 on the conveyor belt 91 and improving the detection efficiency. Through the coordinated action of the rolling of the conveyor belt 91 and the partition plate 92, it is ensured that the display driver body 93 can accurately enter the detection area from the feed port 22, thereby improving the accuracy and reliability of the conveyance, ensuring the accurate connection between the test main board 3 and the display driver body 93, and ensuring the stable detection of the display driver body 93;

[0037] In the third step, after the display driver body 93 in the limit frame 2 is detected, the servo motor 6 is started to rotate the screw rod 61, and the rotation of the screw rod 61 drives the fixed rod 41 and the stopper 5 to move synchronously, and the movement of the fixed rod 41 drives the push plate 4 and the contact block 42 to move, and the movement of the contact block 42 gradually separates from the push block 36, and the elastic reset effect of the spring 34 is used to make the slide bar 32 drive the test main board 3 and the plug 31 to reset, so that the test main board 3 and the plug 31 are separated from the display driver body 93. Since the push plate 4 is located on one side of the limit frame 2, when the test main board 3 and the plug 31 are separated from the display driver body 93, the push plate 4 moves to the rectangular opening 24, and the stopper 5 moves to one side of the display driver body 93. At this time, the push plate 4, the contact block 42 and the stopper 36 are in a state of being moved away from each other. 5 continues to move, and the continued movement of the push plate 4 will apply a thrust to the display driver body 93, so that the display driver body 93 moves along the length direction of the side baffle 25, so that the display driver body 93 is separated from the discharge port 23 and discharged from the discharge port 11 under the action of its own gravity. In the process of pushing the display driver body 93 to discharge, the display driver body 93 is blocked by the inner walls on both sides of the limit frame 2 and the push plate 8, so that the display driver body 93 can be accurately discharged from the discharge port 23, so that the display driver body 93 is pushed between the two side baffles 25, so that the display driver body 93 can accurately fall from the discharge port 11, and accurate discharge is completed, thereby realizing the automatic separation and accurate discharge of the test motherboard 3 and the display driver body 93, reducing manual operations and improving production efficiency;

[0038] In the fourth step, the continued movement of the contact block 42 and the stopper 5 will not cause interference. A stopper 15 is fixedly installed on the upper end of the test platform 1. The stopper 15 is located above the slide slot 14. The stopper 15 is used to limit the reset distance of the slide bar 32. After the display driver body 93 is unloaded, the push plate 4, the fixed rod 41, the contact block 42 and the stopper 5 are reset, ensuring that the contact block 42 can accurately apply force to the push block 36, thereby ensuring that the test motherboard 3 and the plug 31 are reset to the initial state. In the initial state, the test motherboard 3 and The plug 31 is inserted into the insertion port 21, and the stopper 5 is located at the discharge port 23, which is used to limit the side end of the display driver body 93, and cooperates with the limiting of the three side walls of the limiting frame 2 and the limiting of the push plate 8 to achieve comprehensive limiting of the surroundings and the upper and lower ends of the display driver body 93, so that the display driver body 93 can accurately reach the limiting frame 2, and the plug 31 can be accurately inserted into the slot 94 on the display driver body 93, completing reliable and accurate electrical connection, thereby ensuring stable detection of the display driver body 93;

[0039] The fifth step is to penetrate the fixed rod 41 and the stop block 5 through the through rod 12 to limit the movement of the fixed rod 41, the push plate 4 and the stop block 5. The through rod 2 82 penetrates the extension plate 81 to limit the movement of the push plate 8, thereby ensuring its stable movement and avoiding position deviation, thereby ensuring the stability and rationality of the structural design.

[0040] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
