[0026] Please refer to Figures 1-4 , the utility model provides a technical scheme: a kind of measurement structure, comprising:

[0027] mounting base 1, the middle part of the top of mounting base 1 is rotationally connected with electric clamping jaw 2 by bearing;

[0028] The photoelectric measuring assembly arranged on the top of the mounting base 1 comprises a photoelectric sensor 301 fixedly arranged on the top of the mounting base 1, and the photoelectric sensor 301 measures whether the LED lamp plate on the reel is wound to the specified number of turns in the form of infrared ranging, and the top of the mounting base 1 corresponding to the position of the electric clamp jaw 2 is fixedly provided with a sensor mounting bracket 302, and the photoelectric sensor 301 is fixedly installed on the top of the sensor mounting bracket 302, so that the blocking center axis of the probe head of the photoelectric sensor 301 is located on the same plane as the center axis of the reel clamped on the electric clamp jaw 2, and one end of the photoelectric sensor 301 is provided with a transmission wheel, and the transmission wheel is driven to rotate by the driving motor in cooperation with the transmission belt.

[0029] When the LED lamp plate on the reel is wound to the outermost periphery of the reel, the photoelectric sensor 301 detects the LED lamp plate wound on the reel to reach the target distance at this time, so as to realize the purpose of measuring the length of the LED lamp plate on the reel, and at this time, the electric clamp jaw 2 stops rotating and performs subsequent LED lamp plate shearing work.

[0030] The length measuring assembly is arranged on one end of the mounting base 1, and the length measuring assembly indirectly measures the length of the LED lamp plate on the reel by the moving distance of the LED lamp plate, and the length measuring assembly comprises a fixed support 401 fixedly installed on one end of the mounting base 1, one end of the top of the fixed support 401 movably provided with a driving frame 404, and the middle part of the driving frame 404 rotatably connected with a transmission shaft 405 through a bearing, one end of the transmission shaft 405 corresponding to the position of the electric clamp jaw 2 fixedly provided with a follow-up wheel 406, and the other end of the transmission shaft 405 and one end of the electric clamp jaw 2 are respectively provided with an encoder 408 for detecting the number of turns of the transmission shaft 405 and the electric clamp jaw 2, one end of the bottom of the fixed support 401 movably provided with a driving plate 410, one end of the driving plate 410 fixedly provided with a limiting base 411 corresponding to the position of the follow-up wheel 406, and the limiting base 411 is located directly below the follow-up wheel 406, one end of the driving frame 404 fixedly provided with a connecting plate 403, and the bottom of the connecting plate 403 fixedly provided with a first air cylinder 402, the first air cylinder 402 fixedly installed on the middle part of the fixed support 401, one end of the driving frame 404 fixedly provided with a guide rod 407 corresponding to the position of the follow-up wheel 406, and the guide rod 407 is located below the follow-up wheel 406, and the bottom of the driving plate 410 fixedly provided with a second air cylinder 409, and the second air cylinder 409 fixedly installed on one end of the fixed support 401.

[0031] The above structure, when in use, when the LED lamp plate moves, the follow-up wheel 406 is driven to rotate, the LED lamp plate drives the transmission shaft 405 to rotate through the follow-up wheel 406, at this time, the number of rotations of the transmission shaft 405 is detected through the encoder 408 at one end of the transmission shaft 405 to detect the distance of the movement of the LED lamp plate, that is, the length of the LED lamp plate wound on the reel, and the number of rotations of the electric clamp jaw 2 is detected through the encoder 408 at one end of the electric clamp jaw 2, that is, the length of the LED lamp plate wound on the reel is measured again through the number of turns of the LED lamp plate wound on the reel.

[0032] Working principle: in the initial state, the follow-up wheel 406 and the limiting base 411 are separated from each other, the LED lamp plate is first pasted on the reel, at this time, the LED lamp plate is located between the follow-up wheel 406 and the limiting base 411, at this time, the first cylinder 402 and the second cylinder 409 work at the same time, and the driving frame 404 and the driving plate 410 move relatively, so that the limiting base 411 and the follow-up wheel 406 move relatively, and the LED lamp plate is clamped on the inner wall of the limiting base 411, then when the electric clamp jaw 2 starts to work on the reel, the electric clamp jaw 2 first expands in the inside of the reel and clamps the reel, then the driving motor drives the electric clamp jaw 2 to rotate through the transmission belt and the transmission wheel, so that the electric clamp jaw 2 drives the reel to rotate and performs the reel packaging work;

[0033] When measuring, when the LED lamp plate wound on the reel reaches the outermost periphery of the reel, at this time, the photoelectric sensor 301 detects that the LED lamp plate wound on the reel reaches the target distance, so that the length of the LED lamp plate wound on the reel is measured, at this time, the electric clamp jaw 2 stops rotating, and subsequent LED lamp plate cutting work is performed;

[0034] The LED lamp plate is clamped between the follow-up wheel 406 and the limiting base 411, so that when the reel winds the LED lamp plate, the LED lamp plate is pulled to move, and when the LED lamp plate moves, the follow-up wheel 406 is driven to rotate, so that the follow-up wheel 406 drives the transmission shaft 405 to rotate, at this time, the number of rotations of the transmission shaft 405 is detected through the encoder 408 at one end of the transmission shaft 405 to detect the distance of the movement of the LED lamp plate, that is, the length of the LED lamp plate wound on the reel, and the number of rotations of the electric clamp jaw 2 is detected through the encoder 408 at one end of the electric clamp jaw 2, that is, the length of the LED lamp plate wound on the reel is measured again through the number of turns of the LED lamp plate wound on the reel;

[0035] The three measurement methods, i.e. detecting whether the LED lamp plate on the winding disc is wound to the target diameter through the photoelectric sensor 301, detecting the number of turns of the winding disc driven by the motor clamp 2 through the encoder 408 and detecting the number of turns of the transmission shaft 405 through the encoder 408, work together to measure the length of the LED lamp plate wound on the winding disc, two of which are satisfied to complete the determination of the length of the LED lamp plate wound on the winding disc, thereby improving the accuracy of the measurement.

[0036] The guide rod 407 is arranged to be always located in the limiting base 411 and closely contact with the surface of the follower wheel 406, so that the movement of the LED lamp plate can drive the follower wheel 406 to rotate, thereby improving the accuracy of the length measurement of the LED lamp plate wound on the winding disc.
