Description

Technical Field

[0001] The present invention relates to the technical field of linear light strip detection, and in particular to a bending degree detection device for linear light strip production. Background Art

[0002] The bending test in the natural state can reflect the original bending characteristics of the light strip when there is no external force. This is crucial for evaluating the quality of the light strip, because if the light strip is excessively bent or deformed in the natural state, it may mean that there are problems with its materials or manufacturing process, or it has been improperly affected during storage or transportation.

[0003] In the patent document of announcement number CN221725778U, a bending degree detection device for linear light strip production is provided, which includes a workbench, a protective shell and a detection shell. The inner sides of both ends of the workbench are slidably connected with a clamping limit mechanism, the outer side of the clamping limit mechanism is provided with a protective shell, and a linear light strip is provided between the clamping limit mechanisms. The upper end of the workbench is fixedly connected with a detection shell, the outer side of one end of the detection shell is fixedly connected with a motor bracket, the upper end of the motor bracket is fixedly connected with a stepper motor, the top end of the stepper motor main shaft is fixedly connected with a threaded rod, the outer side of the threaded rod is spirally connected with a slider, and the inner side of the lower end of the detection shell is fixedly connected with a threaded rod. The side sliding is connected with a vertical rod, the outer side of the lower end of the vertical rod is fixedly connected to the horizontal plate, and the bottom end of the horizontal plate is fixedly connected with a third spring. The device can complete the multi-point detection function of the linear light belt through the clamping limit mechanism, stepper motor, semicircular block and vertical rod. The overall structure of the device is simple, which can reduce the investment in detection cost, thereby reducing the cost of linear light belt production. At the same time, it can ensure that the bending degree of multiple points on the linear light belt can be detected, which can improve the accuracy of the detection data, and can further ensure the factory quality of the linear light belt to meet the production needs; however, the above patent document still has the following defects in the implementation process: When the device is testing the light strip, the staff is required to manually fix the light strip and then test it. After the test is completed, the staff is required to manually remove the light strip after the test and replace it with another one. Not only do the staff need to repeat the tedious fixing actions, especially during long-term work, it will bring great labor intensity to the workers, and each time the light strip is fixed, it may take tens of seconds or even minutes. For mass-produced light strips, the accumulation of this time will seriously affect production efficiency.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0018] Embodiment 1: Figure 1-5As shown, a bending degree detection device for linear light strip production includes a workbench 1, a shell 11 is fixedly connected to the top of the workbench 1, a fixing plate 12 is fixedly connected to the right end of the shell 11, a placement rack 13 is fixedly connected to the top of the back side of the workbench 1, two fixing tables 14 are fixedly connected to the inner surface of the workbench 1, a laser displacement sensor device 15 is slidably connected to the inner wall of the shell 11, a detection component 2 is arranged at the bottom of the shell 11, and an automatic component 3 is arranged at the top of the workbench 1.

[0019] The laser displacement sensor device 15 mentioned above is composed of a shell and a plurality of laser distance sensors. The plurality of laser distance sensors are installed in the inner cavity of the shell, and the laser emission ports of the plurality of laser distance sensors are placed downward and can directly irradiate the upper end of the linear light strip.

[0020] The above-mentioned laser distance sensor irradiates the laser beam it emits onto the light strip, and the sensor receives the reflected laser signal, measures the distance from the surface of the light strip to the sensor based on the principle of laser flight time or phase difference, and transmits these data to the control room. The height difference between two adjacent laser distance sensors can be compared by computer, and the bending angle of the linear light strip between the two adjacent laser distance sensors can be obtained by dividing the height difference data by the distance between the two adjacent laser distance sensors.

[0021] The number of the above-mentioned laser distance sensors can be increased or decreased according to actual production requirements.

[0022] Specifically, in order to achieve the purpose of reducing the labor intensity of workers by eliminating the need for workers to repeat tedious and fixed actions, refer to Figure 3 and Figure 4 In this embodiment, the detection component 2 includes a bidirectional threaded rod 21, and the left and right outer surfaces of the bidirectional threaded rod 21 are rotatably connected to the inner wall of the shell 11. The top of the fixed plate 12 is fixedly connected to a motor 22, and the output end of the motor 22 is fixedly connected to the right end of the bidirectional threaded rod 21. The outer surface of the bidirectional threaded rod 21 is threadedly connected to two moving blocks 23, and the bottom inner walls of the two moving blocks 23 are rotatably connected to rotating rods 231, and the bottoms of the two rotating rods 231 are rotatably connected to the top of the laser displacement sensor device 15.

[0023] For further information, see Figure 3 In this embodiment, two gears 24 are fixedly connected to the outer surface of the bidirectional threaded rod 21. The two gears 24 are symmetrically arranged with the center of the shell 11. The back of the gear 24 is meshed with a gear plate 241. Slide grooves are provided on the left and right sides of the workbench 1. The right outer surface of the bottom back of the gear plate 241 is slidably connected to the inner wall of the slide groove on the same side.

[0024] During the implementation process, when it is necessary to detect the bending degree of the linear light strip, first place the linear light strip flatly on the top of the placement frame 13, turn on the motor 22 to drive the clockwise bidirectional threaded rod 21 to rotate, and when the bidirectional threaded rod 21 rotates, it will drive the two moving blocks 23 to move closer to each other, and when the moving block 23 moves, it will drive the rotating rod 231 to rotate. During the rotation of the rotating rod 231, it will push the laser displacement sensor device 15 to move downward, so that it can detect the light strip.

[0025] For further information, see Figure 4 In this embodiment, a connecting frame 242 is fixedly connected to the front bottom of the gear plate 241, and a fixing rod 243 is slidably connected to the inner wall of the connecting frame 242. Square holes are opened on the left and right sides of the workbench 1, and the top and bottom of the fixing rod 243 are fixedly connected to the inner wall of the square hole on the same side.

[0026] For further information, see Figure 4 In this embodiment, a circular hole is opened on the top of the connecting frame 242, and a sliding rod 25 is slidably connected to the inner wall of the circular hole. A clamping block 252 is fixedly connected to the bottom of the sliding rod 25. A spring 251 is sleeved on the outer surface of the sliding rod 25. The top of the spring 251 is fixedly connected to the bottom of the connecting frame 242, and the bottom of the spring 251 is fixedly connected to the top of the clamping block 252.

[0027] During the implementation process, the two-way threaded rod 21 can drive the two gears 24 to rotate while rotating clockwise. The gear 24 can drive the gear plate 241 to move downward when it rotates clockwise. When the gear plate 241 moves downward, it will drive the clamping block 252 to move downward through the connecting frame 242, so that its bottom contacts the light strip at the top of the fixed platform 14. After the clamping block 252 contacts the top surface of the light strip, it will push the slide bar 25 to slide in the inner wall of the connecting frame 242. During the sliding process of the slide bar 25, the spring 251 will be squeezed to deform it. The deformed spring 251 will fix the light strip on the top of the fixed platform 14 due to the elastic force generated. The laser displacement sensor device 15 will detect the bending degree of the light strip in its natural state, so that the staff does not have to repeat the cumbersome and fixed actions. It can not only reduce the labor intensity brought by the staff during long-term work, but also reduce the time required to fix the light strip. For the light strips produced in large quantities, the production efficiency is greatly improved.

[0028] Embodiment 2: This embodiment sets an automatic component based on embodiment 1.

[0029] Specifically, in order to achieve the purpose of automatic loading and unloading of light strips, refer to Figure 5 In this embodiment, the automatic component 3 includes a sprocket 31, the right end of the sprocket 31 is fixedly connected to the left end of the bidirectional threaded rod 21, and the inner wall of the workbench 1 is rotatably connected to two rotating rods 32.

[0030] For further information, see Figure 5 In this embodiment, the left end of the rotating rod 32 located at the front is fixedly connected to a flywheel 33, the outer surface of the flywheel 33 and the outer surface of the sprocket 31 are jointly connected to a chain 34, and the outer surfaces of the two rotating rods 32 are jointly connected to a belt 36.

[0031] The flywheel 33 has an internal structural design that allows it to transmit power in one direction only. When the sprocket 31 rotates clockwise, the flywheel can drive the rotating rod 32 to rotate, while when the sprocket 31 rotates counterclockwise, the flywheel will not drive the rotating rod 32 to rotate.

[0032] For further information, see Figure 5 In this embodiment, the outer surfaces of the two rotating rods 32 are fixedly connected with a plurality of rotating rods 35, the tops and bottoms of the plurality of rotating rods 35 located on the front are both arc-shaped, and the tops and bottoms of the plurality of rotating rods 35 located on the back are both provided with card slots.

[0033] During the implementation process, when the first light strip is detected, the motor 22 drives the two-way threaded rod 21 to rotate counterclockwise to release the fixation of the light strip on the top of the fixed platform 14. When the sprocket 31 drives the chain 34 to rotate counterclockwise, it will not drive the flywheel 33 to rotate. After the next light strip is placed on the top of the placement rack 13, the two-way threaded rod 21 is driven by the motor to rotate clockwise. The rotating rod 32 on the front side can drive several rotating rods 35 to rotate while rotating. During the rotation of the rotating rod 35, the light strip after the detection on the top of the fixed platform 14 is automatically removed, and the rotating rod 32 on the back side can drive another light strip to the top of the fixed platform 14 for fixation and then detection during rotation. Not only can the loading and unloading operations of the light strips be completed in a very short time, the detection cycle is greatly shortened, and the production efficiency is improved, but the staff can focus on monitoring the detection process, handling abnormal situations, and performing equipment maintenance, etc., which improves the comfort and safety of work.

[0034] The working principle of the present invention is as follows: when it is necessary to detect the bending degree of the linear light strip, firstly, the linear light strip is placed flat on the top of the placement frame 13, and the motor 22 is turned on to drive the clockwise bidirectional threaded rod 21 to rotate. When the bidirectional threaded rod 21 rotates, it will drive the two moving blocks 23 to move closer to each other. When the moving block 23 moves, it will drive the rotating rod 231 to rotate. During the rotation of the rotating rod 231, the laser displacement sensor device 15 will be pushed to move downward so that it can detect the light strip. When the bidirectional threaded rod 21 rotates, the sprocket 31 will be driven to rotate. When the sprocket 31 rotates, it can drive the flywheel 33 to rotate through the chain 34. When the flywheel 33 rotates, it can drive the rotating rod 32 to rotate. During the rotation of the rotating rod 32, The belt 36 drives another rotating rod 32 to rotate, so that the two rotating rods 32 can rotate at the same time. During the rotation of the rotating rod 32 located at the back, the light strip placed on the top of the placement rack 13 can be driven to the top of the two fixed platforms 14 through the several rotating rods 35 fixed on its surface. The two-way threaded rod 21 can drive the two gears 24 to rotate while rotating clockwise. When the gear 24 rotates clockwise, it can drive the gear plate 241 to move downward. When the gear plate 241 moves downward, it drives the clamping block 252 to move downward through the connecting frame 242, so that its bottom contacts the light strip on the top of the fixed platform 14. After the clamping block 252 contacts the top surface of the light strip, it pushes the sliding rod 25 to slide in the inner wall of the connecting frame 242. The sliding of the sliding rod 25 During the process, the spring 251 will be squeezed to deform, and the deformed spring 251 will fix the light strip on the top of the fixing platform 14 due to the elastic force generated. The laser displacement sensor device 15 will detect the bending degree of the light strip in the natural state, so that the staff does not have to repeat the tedious fixing actions. It can not only reduce the labor intensity of the staff during long-term work, but also reduce the time required to fix the light strip. For the light strips produced in large quantities, the production efficiency is greatly improved. After the first light strip is detected, the motor 22 drives the bidirectional threaded rod 21 to rotate counterclockwise to release the fixation of the light strip on the top of the fixing platform 14, and the sprocket 31 will not drive the flywheel 3 when the chain 34 rotates counterclockwise. 3 rotates, when the next light strip is placed on the top of the placement rack 13, the two-way threaded rod 21 is driven by the motor to rotate clockwise, and the rotating rod 32 located on the front side can drive several rotating rods 35 to rotate while rotating. During the rotation of the rotating rod 35, the light strip after the inspection on the top of the fixing platform 14 is automatically removed, and the rotating rod 32 located on the back side can drive another light strip to the top of the fixing platform 14 for fixing and then inspection when rotating. Not only can the loading and unloading operations of the light strips be completed in a very short time, the inspection cycle is greatly shortened, and the production efficiency is improved, but the staff can focus on monitoring the inspection process, handling abnormal situations and performing equipment maintenance, etc., which improves the comfort and safety of work.
