Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments;

[0026] It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention; furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] Please see Figures 1-3 The LED module brightness detection fixture in the preferred embodiment includes a base plate 1;

[0028] Support frame 2 is installed on top of base plate 1;

[0029] Sleeve 3 is located at the middle of the upper end of support frame 2;

[0030] The support member 4 is rotatably and throughly mounted on the sleeve 3;

[0031] The power mechanism 5 is located at the bottom of the base plate 1 and connected to the bearing component 4;

[0032] Cam 6 is fitted onto the outer wall of sleeve 3;

[0033] Two clamping parts 7 are symmetrically arranged on the bearing part 4 and both are in contact with the cam 6;

[0034] The power supply component 8 is mounted on the carrier component 4 and the support frame 2. The power supply component 8 is used to provide power to the LED module.

[0035] The power mechanism 5 is used to drive the bearing 4 to rotate for automatic switching of workstations; the cam 6 is used to push the passing clamping member 7 to clamp the LED module.

[0036] Specifically, refer to Figure 1-2 The bearing 4 is rotatably connected to the rotating rod 41 through the sleeve 3, and the rotating rod 41 provides axial support for the rotation of the bearing 4; the connecting frame 42 set at the top of the rotating rod 41 is used to install other components; the bearing plate 43 sleeved on the outer wall of the sleeve 3 and the outer wall of the cam 6 and set at the bottom of the connecting frame 42 provides an installation platform for the clamping part 7 and the power socket 82.

[0037] Specifically, refer to Figure 2 The power mechanism 5 includes a servo motor 51 mounted on the top of the base plate 1, which serves as a power source to provide stable rotational power; a transmission wheel 52 mounted on the bottom end of the rotating rod 41 and the output shaft of the servo motor 51; and a transmission belt 53 connecting the two transmission wheels 52. The transmission belt 53 transmits the power of the servo motor 51 to the rotating rod 41, thereby driving the bearing 4 to rotate.

[0038] Specifically, refer to Figure 3 The clamping component 7 is mounted on the top of the support plate 43, and the sleeve 71 provides sliding support for the slide rod 72. The slide rod 72, which can slide through the sleeve 71, can slide along the sleeve 71 and drive the clamping plate 75 to move. Two side plates 73 are mounted on the side wall of the slide rod 72 and are used to connect springs 74. The springs 74, which are located between the side plates 73 and the sleeve 71 and are connected to the side plates 73 and the sleeve 71 at both ends respectively, provide a reset force for the slide rod 72. When the clamping component 7 leaves the cam 6, the springs 74 pull the slide rod 72 to reset and release the LED module. Two clamping plates 75, which are fixed to the top of the support plate 43 and one end of the slide rod 72 respectively, are used to clamp the LED module. The relative movement of the two clamping plates 75 realizes the clamping and releasing of the LED module. The guide wheel 76, which is located at the other end of the slide rod 72 and slides against the cam 6, reduces the friction between the slide rod 72 and the cam 6, so that the slide rod 72 slides more smoothly under the action of the cam 6.

[0039] Specifically, refer to Figure 1-3 The power supply component 8 includes a conductive slip ring 81 mounted on the top of the support frame 2, which enables continuous power supply during rotation; two power sockets 82 mounted on the support plate 43, which are used to connect to the power interface of the LED module; the power sockets 82 and the conductive slip ring 81 are electrically connected by a cable 83, ensuring that the power sockets 82 can continuously obtain power to supply power to the LED module during the rotation of the support component 4.

[0040] Working principle

[0041] During operation, the servo motor 51 starts and drives the rotating rod 41 to rotate through the transmission wheel 52 and the transmission belt 53, thereby causing the support plate 43 of the support component 4 to rotate and realize automatic switching of work positions;

[0042] When the guide wheel 76 of the clamping member 7 passes the cam 6, the cam 6 pushes the guide wheel 76, causing the slide rod 72 to slide along the sleeve 71, and the spring 74 is stretched; the slide rod 72 drives the clamping plate 75 at one end to move closer to the clamping plate 75 on the top of the support plate 43, clamping and fixing the LED module placed on the support plate 43; at the same time, the power socket 82 is connected to the power interface of the LED module, and the conductive slip ring 81 continuously supplies power to the power socket 82 through the cable 83, so that the LED module is powered on and emits light for brightness detection;

[0043] When the carrier 4 continues to rotate, and the guide wheel 76 of the clamping member 7 leaves the cam 6, the spring 74 resets, pulls the slide bar 72 to slide in the opposite direction, and releases the LED module, making it easier to load and unload. With the two clamping members 7, the other LED module can be loaded and unloaded while one LED module is being tested, eliminating the need to wait for the LED module to be picked up and put away after each test, which greatly improves the testing efficiency.

[0044] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
