Description

Technical Field

[0001] The utility model belongs to the technical field of LED lamp detection, in particular to a clamping mechanism for LED lamp detection. Background Art

[0002] The clamping mechanism used for LED lamp testing is an indispensable key equipment in the LED production and quality control process. With the widespread application of LED technology, the requirements for LED product quality are increasing day by day, which makes the clamping mechanism particularly important in ensuring the stable and accurate testing of LED lamps.

[0003] After searching, the existing patent (Announcement No.: CN219189972U) discloses a clamping mechanism for automobile LED lamp head detection, which belongs to the technical field of automobile LED lamp heads, including a support table placed on a processing table for automobile LED lamp head detection and processing, support blocks are provided at the four corners of the bottom surface of the support table, and a rotating processing disk is rotatably installed on the top surface of the support table. The top surface of the rotating processing disk is symmetrically and slidably connected with two clamping plates for clamping automobile LED lamp heads, and the two clamping plates are rotatably installed with clamping discs on the opposite sides, and the two clamping discs are bonded with rubber anti-skid pads on the opposite sides. The clamping mechanism for automobile LED lamp head detection meets the clamping use of automobile LED lamp heads of different specifications, and can be rotated by the rotating processing disk to drive the angle position of the automobile LED lamp head to meet the processing needs of different positions, and can limit and lock the rotating processing disk through the locking component to meet the use needs of different occasions.

[0004] However, in the actual use of the above solution, the clamped LED lamp is rotated by rotating the rotating processing disk, thereby realizing the horizontal multi-angle detection of the LEND lamp. However, the size and shape of LED lamps vary during the detection process, and some LED lamps may need to adjust the angle and position in multiple directions during detection. If the clamping mechanism can only rotate horizontally, it may not be able to fully meet the detection needs of all types of LED lamps.

[0005] To this end, the utility model provides a clamping mechanism for LED lamp detection. Utility Model Content

[0006] In order to make up for the shortcomings of the prior art and solve the problem that the angle and position need to be adjusted in multiple directions during detection, if the clamping mechanism can only rotate horizontally, it may not be able to fully meet the detection requirements of all types of LED lights. The utility model proposes a clamping mechanism for LED light detection.

[0007] The technical solution adopted by the utility model to solve its technical problems is: a clamping mechanism for LED lamp detection described in the utility model comprises a base, the top of the base is fixedly connected to a first supporting frame opposite to the left and right, the top of the base is fixedly connected to a second supporting frame opposite to the front and back, the right side of the top of the base is fixedly connected to a first motor, the output end of the first motor is fixedly connected to a worm, the top of the worm is meshingly connected to a worm wheel, the top of the worm wheel is fixedly connected to a supporting plate, the top inner side of the second supporting frame is fixedly connected to a limiting column, the bottom end of the support plate is fixedly connected to a limiting frame opposite to the front and back, the limiting frame is slidably connected to the limiting column, the top of the support plate is rotatably connected to a fixing frame, the inner side of the top of the fixing frame is fixedly connected to the second motor, the right side outer wall of the second motor is fixedly connected to a fixing clamp, and the right side of the fixing clamp is provided with a fixing arm assembly opposite to the front and back;

[0008] Through the above technical solution, the first motor drives the worm and thus the worm wheel to rotate, and the worm wheel drives the support plate to rotate. At the same time, the support plate drives the fixed frame and the second motor, the pneumatic clamp and the fixed arm assembly to adjust the angle of the fixed LED lamp, so that multi-angle detection can be performed.

[0009] Furthermore, the fixed arm assembly includes a nut, a front-to-rear clamping arm is fixedly connected to the left side of the fixed clamp, a bolt is rotatably connected to the inner end of the left side of the clamping arm, a sliding groove is provided at the middle end of the left side of the clamping arm, a sliding rod is slidably connected to the inner side of the sliding groove, a limiting ring is fixedly connected to the outer side of the sliding rod, a spring is arranged on the outer side of the sliding rod, a fixing plate is fixedly connected to the inner end of the sliding rod, and a corresponding nut is fixedly connected to the outer end of the fixing plate;

[0010] Through the above technical scheme, the spring uses the inner walls of the sliding groove as stress points to push the fixing plate inward at the same time, thereby achieving flexible clamping of the LED lamp. When rigid clamping is required, it is only necessary to push the fixing plate outward to compress the spring, and at the same time connect the nut fixed at one end of the outer side of the fixing plate with the bolt. The nut is connected by turning the bolt to fix the clamping arm and the fixing plate, thereby achieving rigid clamping and increasing the applicability of the device.

[0011] Furthermore, a groove is provided in the middle of the inner side of the top of the base, and the inner side of the groove is rotatably connected with left and right opposing limiting rods, and the limiting rods are rotatably connected with the limiting frame;

[0012] Through the above technical solution, the worm wheel is supported by the left and right opposite grooves, thereby reducing the friction between the worm wheel and the top of the base.

[0013] Furthermore, a damping layer is provided between the fixing frame and the supporting plate;

[0014] Through the above technical solution, the friction between the support plate and the fixing frame can be increased by the damping layer, thereby increasing the stability between the fixing frame and the support plate. After the fixing frame is rotated to a certain angle, the angle can be limited by the damping layer.

[0015] Furthermore, a rubber layer is provided at one end of the inner side of the fixing plate;

[0016] Through the above technical solution, a certain buffer is provided between the fixing plate and the LED lamp through the rubber layer, thereby avoiding wear on the surface of the LED lamp.

[0017] Furthermore, the outer diameter of the limiting ring is larger than the inner wall diameter of the sliding groove;

[0018] Through the above technical solution, the sliding rod is limited by the limiting ring, thereby preventing the sliding rod from falling off the clamping arm.

[0019] The beneficial effects of the utility model are as follows:

[0020] 1. The clamping mechanism for LED lamp detection described in the utility model drives the worm to rotate through the first motor, thereby driving the worm wheel and the limit frame, support plate, fixing frame, second motor, pneumatic clamp and fixed arm assembly to rotate left and right longitudinally, and at the same time drives the pneumatic clamp and fixed arm assembly to rotate front and back longitudinally through the second motor, so as to adjust the LED lamp at multiple angles, which can adapt to LED lamps of various shapes and sizes. LED lamps are designed differently, and some may need to be adjusted and rotated in multiple directions in order to achieve the best angle and position during the detection process. The multi-angle adjustment function enables the clamping mechanism to flexibly respond to different detection requirements and ensure the comprehensiveness and accuracy of the detection.

[0021] 2. The clamping mechanism for LED lamp detection described in the utility model can adjust the clamping force of the device through the cooperation of bolts, nuts, fixing plates, sliding rods, limit rings and springs, and can flexibly switch between soft and hard clamping, which means that the clamping mechanism can be adjusted according to the characteristics of the specific LED lamp to ensure that the clamping force is sufficiently stable without damaging the outer casing or internal components of the LED lamp.
