[0002] The LED production process mainly includes die bonding, wire bonding, dispensing, cutting, sizing, and packaging. The first three processes are called LED packaging, which is a very important part of the entire LED production process. Its main purpose is to ensure the correct electrical connection between the LED chip and the LED bracket circuit, and to protect the chip from mechanical, heat, moisture and other external impacts. Cutting is the process of separating each LED from the bracket. Sizing is the process of inspecting whether the produced LED products are qualified. It is an essential process before the finished products leave the factory.

[0016] According to one embodiment of the present invention, in conjunction with the appended drawings Figures 1-5 As shown.

[0017] Example 1 An LED array testing device includes a base plate 1, a support assembly 2 connected to the bottom surface of the base plate 1, and a conveying assembly 3 connected to the outer surface of the base plate 1. The conveying assembly 3 includes a first motor 301, a rotating column 302, two first bearings 303, a conveying roller 304, multiple sets of second bearings 305, multiple rotating rods 306, multiple auxiliary rollers 307, and a conveyor belt 308. A detection assembly 4 is connected to the upper surface of the base plate 1. The detection assembly 4 includes a support frame 401, a second motor 402, a first threaded rod 403, a third bearing 404, a first nut 405, a support plate 406, and a detection element 40. 7. The upper surface of the base plate 1 is connected to a positioning assembly 5. The positioning assembly 5 includes two cylinders 501, a support frame 502, a third motor 503, a second threaded rod 504, two fourth bearings 505, two second nuts 506, and two clamping plates 507. Specifically, the detection component 407 includes an industrial camera and a light sensor, both of which are existing technologies and will not be described in detail here. Specifically, the detection component 407, the first motor 301, the second motor 402, the third motor 503, and the two cylinders 501 are controlled by a PLC. The PLC is an existing device and will not be described in detail here.

[0018] Example 2 In this embodiment, the support assembly 2 includes multiple support legs 201, each support leg 201 being connected to the bottom surface of the base plate 1. Each support leg 201 has a base 202 connected to its bottom surface. The cooperation between the support legs 201 and the base 202 effectively supports the device, increasing its stability. A first motor 301 is connected to the outer surface of the base plate 1, and its output end is connected to a rotating column 302. Two first bearings 303 are embedded in the inner wall of the base plate 1, and the inner rings of the two first bearings 303 are connected to the outer surface of the rotating column 302. The outer surface is connected to a conveyor roller 304, and the inner wall of the base plate 1 is inlaid with multiple sets of second bearings 305. The inner ring of each set of second bearings 305 is connected to a rotating rod 306. The outer surface of each rotating rod 306 is connected to an auxiliary roller 307. The outer surface of each auxiliary roller 307 and the outer surface of the conveyor roller 304 are connected to a conveyor belt 308. The first motor 301 drives the rotating column 302 to rotate, which in turn drives the conveyor roller 304 to rotate. Thus, the conveyor roller 304 rotates with the help of the auxiliary rollers 307 and the conveyor belt 308, thereby driving the LED to be conveyed.

[0019] Example 3 A support frame 401 is connected to the upper surface of the base plate 1. A second motor 402 is connected to the upper surface of the support frame 401. The output end of the second motor 402 is connected to a first threaded rod 403. Two third bearings 404 are embedded in the inner wall of the support frame 401. The inner rings of the two third bearings 404 are connected to the outer surface of the first threaded rod 403. A first nut 405 is threaded onto the outer surface of the first threaded rod 403. A support plate 406 is connected to the outer surface of the first nut 405. A detection element 407 is connected to the bottom surface of the support plate 406. The second motor 402 drives the first threaded rod 403 to rotate. The rotation causes the first threaded rod 403 to drive the first nut 405 for adjustment, which in turn causes the first nut 405 to drive the support plate 406 for adjustment. This allows the detection piece 407 to be adjusted according to different LED models. The inner wall of the support frame 401 is provided with a sliding groove 6, and a slider 7 is slidably connected to the inner wall of the sliding groove 6. The outer surface of the slider 7 is connected to the outer surface of the first nut 405. Through the cooperation of the sliding groove 6 and the slider 7, the adjustment of the first nut 405 can be effectively assisted, increasing the stability of the first nut 405 during adjustment and limiting its movement to prevent the device from malfunctioning.

[0020] Example 4 Two cylinders 501 are connected to the upper surface of the base plate 1. The output ends of the two cylinders 501 are connected to a support frame 502. A third motor 503 is connected to the outer surface of the support frame 502. The output end of the third motor 503 is connected to a second threaded rod 504. Two fourth bearings 505 are embedded in the inner wall of the support frame 502. The inner rings of the two fourth bearings 505 are connected to the outer surface of the second threaded rod 504. Two second nuts 506 are connected to the outer surface of the second threaded rod 504. The bottom surfaces of the two second nuts 506 are connected to clamping plates 507. The cylinders 501 drive the support frame 502 to adjust to a suitable height. Then, the third motor 503 drives the second threaded rod 504 to rotate, causing the second threaded rod 504 to drive the two second threaded rods 504. The mother 506 is adjusted, thereby causing the two second nuts 506 to move the two clamping plates 507, thus clamping and fixing the LED. The support frame 502 is internally connected to a slide rod 8, and two moving blocks 9 are slidably connected to the outer surface of the slide rod 8. The bottom surface of the two moving blocks 9 is connected to the upper surface of the second nut 506. Through the cooperation of the slide rod 8 and the moving blocks 9, the second nut 506 can be effectively assisted in adjustment, increasing the stability of the second nut 506 during adjustment. The two clamping plates 507 are connected to soft pads 10 on their adjacent sides. Both soft pads 10 are made of rubber. The design of the rubber soft pads 10 can effectively buffer the clamping force and prevent the LED from being damaged on the surface or internal structure due to squeezing during positioning.

[0021] In use, the LED to be tested is first placed on the conveyor belt 308. The first motor 301 is started, causing the rotating column 302 to rotate using the first bearing 303, which in turn drives the conveyor roller 304 to rotate. This, in conjunction with the auxiliary roller 307, drives the conveyor belt 308 to move, thus conveying the LED to the testing area. Then, the cylinder 501 is started to adjust the support frame 502 to a suitable height. The third motor 503 is started, causing the second threaded rod 504 to rotate using the fourth bearing 505, which in turn causes the second nut 506 to move the clamping plate 50. 7 moves with the cooperation of slide bar 8 and moving block 9, thereby clamping and fixing the LED. After positioning, the second motor 402 is started, causing the first threaded rod 403 to rotate using the third bearing 404. This causes the first threaded rod 403 to drive the first nut 405 to adjust with the cooperation of slide groove 6 and slider 7. This causes the first nut 405 to drive the support plate 406 and the detection piece 407 to adjust to the appropriate position, so that the detection piece 407 is close to the LED for parameter detection. After the detection is completed, all components are reset, and the conveyor belt 308 transports the LED to the next stage.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
