Description

A testing device for LED light boards Technical Field

[0001] This utility model relates to the field of testing LED light boards, and more particularly to a testing device for LED light boards. Background Technology

[0002] An LED light board is an electronic component that assembles multiple light-emitting diode chips onto a specific substrate through circuit connections, and is equipped with driving circuits and other auxiliary components to achieve lighting functions. An LED light board testing device is used to test and evaluate various performance parameters of the LED light board. By testing the light board's optical parameters such as luminous flux, color coordinates, and color rendering index, it is ensured whether the LED light board's brightness is uniform, its color is accurate, and whether the product meets standards.

[0003] In the process of developing this application, the inventors discovered the following problems with the prior art: Existing LED light board testing devices generally include a testing device body, tooling fixtures, CCD cameras, and other structures. Most existing tooling fixtures can only be fixed in two directions: left and right or front and back. If there is shaking or vibration, the light board will move in the direction that is not fixed, which will lead to inaccurate test data. At the same time, most existing cameras and other structures are in fixed positions and cannot be flexibly adjusted, resulting in insufficient test data.

[0004] Therefore, those skilled in the art have provided a testing device for LED light boards to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a testing device for LED light boards. The fixing mechanism prevents the light board from shifting due to shaking or other factors, while the adjustment mechanism makes the test data more accurate.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a testing device for an LED light board, comprising a fixing mechanism, an adjusting mechanism, and a housing. The fixing mechanism includes two No. 1 clamping plates, two racks, a No. 2 motor, and two No. 2 clamping plates. The bottom of one end of the two No. 1 clamping plates is fixedly connected to the top of the two racks away from the No. 2 motor. The inner walls of the two No. 2 clamping plates are threaded with bidirectional screws.

[0007] The adjustment mechanism includes a screw, a slider is threadedly connected to the outer wall of the screw, a limit rod is slidably connected to the inner wall of the slider near the bottom, and limit blocks are fixedly connected to both ends of the limit rod.

[0008] Furthermore, both of the limiting blocks are fixedly disposed on both sides of the inner wall of the housing, and both of the racks are slidably disposed on the inner wall of the housing.

[0009] Furthermore, a camera is fixedly connected to the bottom of the slider, an indicator light is fixedly connected to the top of the housing near the front end, and a computer is fixedly connected to the front end of the housing near the No. 3 motor.

[0010] Furthermore, a No. 3 motor is fixedly connected to the inner wall of one of the two limiting blocks. The output end of the No. 3 motor is fixedly connected to the end of the No. 1 screw near the No. 3 motor. The end of the No. 1 screw away from the No. 3 motor is rotatably disposed on the inner wall of the limiting block away from the No. 3 motor.

[0011] Furthermore, the bottoms of the two No. 1 clamping plates are slidably connected to the inner wall of the housing, and the bottoms of the two No. 2 clamping plates are slidably connected to the inner wall of the housing.

[0012] Furthermore, the bidirectional screw is rotatably mounted on the inner wall of the housing and located at the upper end of the two racks. A No. 1 motor is fixedly mounted on the inner wall of the front end of the housing, and the output end of the No. 1 motor is fixedly connected to the front end of the bidirectional screw.

[0013] Furthermore, the second motor is fixedly installed on the inner wall of the housing and located in the lower middle part of the two racks. A gear is fixedly connected to the output end of the second motor, and the gear meshes with the two racks.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a testing device for an LED light panel. When a second motor starts working, it drives a gear to rotate counter-clockwise. The gear causes two racks to move a first clamping plate towards the gear, fixing both sides of the light panel. Simultaneously, the first motor starts working, driving a bidirectional screw to rotate. The bidirectional screw causes two second clamping plates to move towards the gear, fixing the front and rear ends of the light panel. By fixing the four sides of the light panel, the testing is guaranteed to be unaffected by shaking or other disturbances.

[0016] 2. The present invention proposes a testing device for LED light panels. When the No. 3 motor starts working, it drives the No. 1 screw to rotate. The rotation of the No. 1 screw causes the slider to move left and right along the limit rod. The left and right movement of the slider further drives the camera at the bottom to move left and right, so as to perform a more comprehensive test on the light panel at the bottom and make the data test more complete.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Referring to Figures 1-4, one embodiment of this utility model provides an LED light board testing device, including a fixing mechanism 1, an adjusting mechanism 2, and a housing 3. The fixing mechanism 1 includes two first clamping plates 101, two racks 102, a second motor 104, and two second clamping plates 106. The bottom of one end of the two first clamping plates 101 is fixedly connected to the top of the two racks 102 away from the second motor 104. The inner walls of the two second clamping plates 106 are threaded with bidirectional screws 107. The adjusting mechanism 2 includes a first screw 202. The outer wall of the first screw 202 is threaded with a slider 206. The inner wall of the slider 206 near the bottom is slidably connected to a limit rod 201. The two ends of the limit rod 201 are respectively fixedly connected to limit blocks 204.

[0025] Specifically, the light panel is placed on a platform near the top of the housing 3, between two clamping plates 101 and two clamping plates 106. Motor 104 operates to rotate gear 105, which in turn causes two racks 102 to move clamping plates 101 along the inner wall of the housing 3 towards gear 105, fixing both sides of the light panel. Motor 103 operates to rotate a bidirectional screw 107, which in turn causes two clamping plates 106 to move along the inner wall of the housing 3 towards gear 105, fixing the front and rear ends of the light panel. After all four sides of the light panel are fixed, motor 203 operates to rotate screw 202, which causes slider 206 to slide left and right along the outer wall of limit rod 201. Slider 206 is restricted by limit rod 201 and cannot rotate, only move. Slider 206 drives the camera 205 at the bottom to move left and right, allowing for a more comprehensive test of the light panel at the bottom.

[0026] Referring to Figures 1-4, both limiting blocks 204 are fixedly mounted on both sides of the inner wall of the housing 3. Both racks 102 are slidably mounted on the inner wall of the housing 3. A camera 205 is fixedly connected to the bottom of the slider 206. An indicator light 4 is fixedly connected to the top of the housing 3 near the front end. A computer 5 is fixedly connected to the front end of the housing 3 near the third motor 203. The third motor 203 is fixedly connected to the inner wall of one of the limiting blocks 204. The output end of the third motor 203 is fixedly connected to the end of the first screw 202 near the third motor 203. The end of the first screw 202 away from the third motor 203 is rotatably mounted on the far side of the two limiting blocks 204. The bottom of the two No. 1 clamping plates 101 and the bottom of the two No. 2 clamping plates 106 are slidably connected to the inner wall of the housing 3. The bidirectional screw 107 is rotatably mounted on the inner wall of the housing 3 and located at the upper end of the two racks 102. The No. 1 motor 103 is fixedly mounted on the inner wall of the front end of the housing 3. The output end of the No. 1 motor 103 is fixedly connected to the front end of the bidirectional screw 107. The No. 2 motor 104 is fixedly mounted on the inner wall of the housing 3 and located in the middle and lower part of the two racks 102. The output end of the No. 2 motor 104 is fixedly connected to a gear 105, which meshes with the two racks 102.

[0027] Specifically, the rack 102 slides on the inner wall of the housing 3 and is restricted by the housing 3 to prevent tilting. The camera 205 is a CCD camera, and the slider 206 can drive the camera 205 to move left and right, so that it can test the lamp board more comprehensively. The computer 5 can display the test results. The two limit blocks 204 provide fixation and support for the third motor 203 and the first screw 202, respectively. The bidirectional screw 107 is provided with opposite threads, which can make the two second clamps 106 move in opposite directions. The inner wall of the front end of the housing 3 provides support and fixation for the second motor 104, and the inner wall of the housing 3 provides support and fixation for the bidirectional screw 107. The gear 105 can drive the two racks 102 to move.

[0028] Working principle: The lamp panel is placed between two No. 1 clamping plates 101 and two No. 2 clamping plates 106. Then, the No. 2 motor 104 is started, and the output end drives the gear 105 to rotate. The gear 105 causes the two racks 102 at the front and rear to move the No. 1 clamping plate 101 at the top towards the gear 105, fixing the horizontal direction of the lamp panel. The No. 1 motor 103 is started, and the output end rotates, driving the bidirectional screw 107 to rotate. The bidirectional screw 107 causes the two No. 2 clamping plates 106 to move towards the gear 105, fixing the vertical direction of the lamp panel.

[0029] Secondly, after the front, back, left, and right sides of the light panel are fixed, the output end of motor 203 is started to rotate, which drives screw 202 to rotate. Screw 202 causes slider 206 to move left and right. Screw 206 drives camera 205 at the bottom to move left and right, thus testing the light panel at the bottom.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
