However, the existing lamp board detection is completed manually, which is easily affected by human factors, resulting in low detection efficiency and accuracy of the lamp board. Summary of the Invention

[0003] An embodiment of this application provides a lamp board detection device for solving the problems of low detection efficiency and accuracy of lamp boards in the prior art.

[0004] To solve the above technical problems, an embodiment of this application provides a lamp board detection device, which adopts the following technical solutions:

[0005] A lamp board detection device includes a frame and the following components all arranged on the frame:

[0006] A loading platform for loading the lamp board to be detected;

[0007] A transfer mechanism, which is in transmission connection with the loading platform and is used to drive the loading platform to move between a first station and a second station;

[0008] An appearance detection mechanism arranged at the first station for performing appearance detection on the lamp board to be detected on the loading platform;

[0009] An optical performance detection mechanism includes a seal, a lifting platform, and a first driving member all arranged at the second station; the seal is installed on the lifting platform and is used to seal and isolate the lamp beads on the lamp board to be detected; the output end of the first driving member is connected to the lifting platform and is used to drive the lifting platform to approach or move away from the loading platform when the transfer mechanism transports the loading platform to the second station.

[0010] Furthermore, the number of the appearance detection mechanisms is multiple;

[0011] Each appearance detection mechanism is used to detect different surfaces of the lamp board to be detected.

[0012] Furthermore, the appearance detection mechanism includes a camera and a second driving member. The second driving member is installed on the frame, and the output end of the second driving member is connected to the camera for driving the camera to move horizontally.

[0013] Furthermore, the seal includes a circuit board and an isolation board;

[0014] The circuit board and the isolation board are sequentially installed on one side of the lifting platform close to the second station; the isolation board is provided with a lamp hole corresponding to the shape of the lamp of the to-be-tested lamp board.

[0015] Further, the lamp board detection device further includes a positioning mechanism; the positioning mechanism includes a positioning guide post arranged at the second station;

[0016] The bearing platform is provided with a positioning hole for cooperating with the positioning guide post.

[0017] Compared with the prior art, the embodiments of the present application mainly have the following beneficial effects: In practical applications, initially, the bearing platform is located at the first station. After placing the to-be-tested lamp board on the bearing platform, the appearance of the lamp board is first detected by the appearance detection mechanism. After the appearance detection of the lamp board passes, the bearing platform is transferred to the second station by the transfer mechanism. Then, the first driving member drives the lifting platform to approach the bearing platform at the second station, so that the sealing member seals the to-be-tested lamp board on the bearing platform, and different lamp beads on the to-be-tested lamp board are isolated separately to avoid interference from other light rays and improve the detection accuracy. Then, an optical analysis instrument (such as an optical sensor, a color temperature sensor, a spectral sensor, etc.) on the sealing member can perform optical detection on the to-be-tested lamp board. After the detection is completed, the first driving member drives the lifting platform to reset, so that the sealing member resets. Then, the bearing platform is conveyed from the second station to the first station by the transfer mechanism. In this way, the automatic detection of the appearance and optical performance of the to-be-tested lamp board is realized, and the detection efficiency and detection accuracy of the lamp board are effectively improved.

[0025] Refer to Figure 1 and Figure 2 , an embodiment of this application provides a lamp board detection device, including a frame 100 and the following components all provided on the frame 100:

[0026] A carrying platform 200 for carrying the lamp board 700 to be tested;

[0027] A transfer mechanism 300, drivingly connected to the carrying platform 200, for driving the carrying platform 200 to move between a first station 310 and a second station 320;

[0028] An appearance detection mechanism 400 provided at the first station 310 for performing appearance detection on the lamp board 700 to be tested on the carrying platform 200;

[0029] The optical performance detection mechanism 500 includes a seal 510, a lifting platform 520, and a first driving member 530, all of which are disposed at the second station 320. The seal 510 is installed on the lifting platform 520 and is used to seal and isolate the lamp beads on the to-be-tested lamp board 700. The output end of the first driving member 530 is connected to the lifting platform 520 and is used to drive the lifting platform 520 to approach or move away from the carrying platform 200 when the transfer mechanism 300 transports the carrying platform 200 to the second station 320.

[0030] In practical applications, initially, the carrying platform 200 is located at the first station 310. After the to-be-tested lamp board 700 is placed on the carrying platform 200, the appearance of the lamp board is first detected by the appearance detection mechanism 400. After the appearance detection of the lamp board passes, the carrying platform 200 is transferred to the second station 320 by the transfer mechanism 300. Then, the first driving member 530 drives the lifting platform 520 to approach the carrying platform 200 at the second station 320, so that the seal 510 seals the to-be-tested lamp board 700 on the carrying platform 200, and different lamp beads on the to-be-tested lamp board 700 are individually isolated to avoid interference from other light rays and improve the detection accuracy. Then, an optical analysis instrument (such as an optical sensor, a color temperature sensor, a spectral sensor, etc.) on the seal 510 can perform optical detection on the to-be-tested lamp board 700. After the detection is completed, the first driving member 530 drives the lifting platform 520 to reset, so that the seal 510 resets. Then, the transfer mechanism 300 transports the carrying platform 200 from the second station 320 to the first station 310. In this way, the automatic detection of the appearance and optical performance of the to-be-tested lamp board 700 is realized, and the detection efficiency and detection accuracy of the lamp board are effectively improved.

[0031] Further, the first driving member 530 can be a motor, a cylinder, a hydraulic cylinder, etc., and no specific limitation is made here.

[0032] In some embodiments, the transfer mechanism 300 is a lead screw transmission mechanism, a belt transmission mechanism, etc., and no specific limitation is made here.

[0033] In some embodiments, the number of the appearance detection mechanisms 400 is multiple; each appearance detection mechanism 400 is used to detect different surfaces of the to-be-tested lamp board 700. In this way, multiple appearance detection mechanisms 400 can respectively detect different surfaces of the to-be-tested lamp board 700, effectively improving the detection accuracy.

[0034] In some embodiments, the appearance detection mechanism 400 includes a camera 410 and a second driving member 420. The second driving member 420 is installed on the frame 100, and the output end of the second driving member 420 is connected to the camera 410 and is used to drive the camera 410 to move horizontally.

[0035] In practical applications, the camera 410 captures the appearance image of the to-be-tested lamp board 700 on the first station 310, and then transmits it to the system for image analysis, so as to realize the appearance detection of the to-be-tested lamp board 700.

[0036] Moreover, the second driving member 420 can drive the camera 410 to move, so as to adjust the shooting position of the camera 410, and further meet different usage requirements, with wide applicability.

[0037] Furthermore, the second driving member 420 can be a motor, a cylinder, a hydraulic cylinder, etc., which is not specifically limited herein.

[0038] In some embodiments, the seal 510 includes a circuit board 511 and a partition board 512; the circuit board 511 and the partition board 512 are successively installed on one side of the lifting platform 520 close to the second station 320; the partition board 512 is provided with a lamp hole 5121 corresponding to the lamp shape of the to-be-tested lamp board 700.

[0039] Understandably, an optical analysis instrument (such as an optical sensor, a color temperature sensor, a spectral sensor, etc.) is integrated on the circuit board 511; in practical applications, after the first driving member 530 drives the lifting platform 520 to move close to the to-be-tested lamp board 700 on the second station 320, the partition board 512 gradually approaches the to-be-tested lamp board 700 until the partition board 512 abuts against the to-be-tested lamp board 700, and the lamp beads on the to-be-tested lamp board 700 are located in the lamp hole 5121, and then are collected and analyzed by the optical analysis instrument on the circuit board 511, so as to realize the automatic detection of the optical performance of the to-be-tested lamp board 700, effectively improving the detection efficiency and detection accuracy.

[0040] In some embodiments, the lamp board detection device further includes a positioning mechanism 600; the positioning mechanism 600 includes a positioning guide post 610 provided on the second station 320; the carrying platform 200 is provided with a positioning hole (not shown in the figure) for cooperating with the positioning guide post 610.

[0041] Understandably, after the to-be-tested lamp board 700 moves to the second station 320, the positioning guide post 610 is inserted into the positioning hole (not shown in the figure), so as to realize the positioning of the position of the carrying platform 200, thereby ensuring the sealing performance of the seal 510 for the to-be-tested lamp board 700, and avoiding the wear of the lamp beads of the to-be-tested lamp board 700 caused by the position deviation of the carrying platform 200.

[0042] Obviously, the embodiments described above are only a part of the embodiments of this application, rather than all of them. The preferred embodiments of this application are shown in the accompanying drawings, but they do not limit the patent scope of this application. This application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of this application more thorough and comprehensive.
