Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED light strip production technology, and more specifically, to an anti-jamming device for an electric feeder used in LED light strip production. Background Technology
[0002] LED light strips are strip-shaped lighting devices that assemble surface-mount LEDs onto flexible printed circuit boards (FPCs) or rigid PCBs. Due to their lifespan of 80,000 to 100,000 hours and energy-saving and environmentally friendly characteristics, they are widely used in the decorative field. The production process requires conveying, cutting, punching, and metallizing the flexible FPC or PCB backplane to improve conductivity. In the current process of feeding flexible backsheet strips, if the processing mechanism jams and the feeding mechanism cannot react in time, a large amount of flexible backsheet waste is easily generated, causing equipment damage and material waste. Furthermore, due to the inertia of the equipment operation, it takes time to stop in an emergency, and the losses are uncontrollable. Summary of the Invention
[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide an anti-jamming device for an electric feeder used in LED strip production, so as to solve the problems in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution; An anti-jamming device for an electric feeder used in LED strip production includes a base and a feeding mechanism, a guide frame, and an anti-jamming detection mechanism mounted on the base. The feeding mechanism includes a feeding roller and a braking mechanism. The braking mechanism is mounted on the base to brake the feeding roller. The anti-jamming detection mechanism includes a support frame, a square channel, two lower rollers, and a pressure sensor. The support frame is fixedly installed on the guide frame, the square channel is fixedly installed on the support frame, the two lower rollers are rotatably installed inside the square channel, and the pressure sensor is installed on the square channel and located between the two lower rollers. A controller is fixedly installed on the base. The controller is used to receive the signal from the pressure sensor and then control the braking mechanism to stop the feeding roller.
[0005] As a further description of the above technical solution: the pressure sensing element includes an internal threaded sleeve, an adjusting screw, a pressure sensing block, and a pressure roller. The bottom end of the internal threaded sleeve is fixedly connected to the interior of the square channel. The bottom end of the adjusting screw extends into the interior of the internal threaded sleeve and is threadedly connected thereto. The bottom end of the adjusting screw is rotatably connected to the pressure sensing block. The outer side of the pressure sensing block slides into the interior of the internal threaded sleeve.

[0009] As a further description of the above technical solution: A set of driven output rollers is fixedly installed on the top of the guide frame.
[0010] Compared with existing technologies, the advantages of this utility model are: This solution uses a pressure sensor to detect the tension changes of the flexible backplate strip at the output end of the entire feeding mechanism in real time and transmits the data to the controller. Based on the tension changes, it can determine the tape jamming fault and implement automatic shutdown control.

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0014] To address the problem in the current flexible backsheet strip feeding process where jamming occurs in the processing mechanism and the feeding mechanism cannot react in time, easily resulting in a large amount of flexible backsheet waste, causing equipment damage and material waste, the following Implementation Example 1 is proposed: Please see Figures 1-4 In this utility model, the anti-jamming device of the electric feeder for LED light strip production includes a base 1 and a feeding mechanism 2, a guide frame 3 and an anti-jamming detection mechanism 4 installed on the base 1. The feeding mechanism 2 includes a feeding roller 5 and a braking mechanism 6. The braking mechanism 6 is installed on the base 1 to brake the feeding roller 5. A controller 7 is fixedly installed on the base 1. The controller 7 is used to receive the signal from the pressure sensor 44 and then control the braking mechanism 6 to stop the feeding roller 5.
[0015] The anti-jamming detection mechanism 4 includes a support frame 41, a square channel 42, two lower rollers 43, and a pressure sensor 44. The support frame 41 is fixedly installed on the guide frame 3, the square channel 42 is fixedly installed on the support frame 41, the two lower rollers 43 are rotatably installed inside the square channel 42, and the pressure sensor 44 is installed on the square channel 42 and located between the two lower rollers 43. Two sets of guide rollers 31 are installed on the guide frame 3, and a set of driven output rollers 32 is fixedly installed on the top of the guide frame 3.
[0016] The pressure sensing element 44 includes an internal threaded sleeve 441, an adjusting screw 442, a pressure sensing block 443, and a pressure roller 444. The bottom end of the internal threaded sleeve 441 is fixedly connected to the inside of the square channel 42. The bottom end of the adjusting screw 442 extends into the inside of the internal threaded sleeve 441 and is threadedly connected to it. The bottom end of the adjusting screw 442 is rotatably connected to the pressure sensing block 443. The outer side of the pressure sensing block 443 slides into the inside of the internal threaded sleeve 441. The bottom of the pressure sensing block 443 is rotatably connected to the pressure roller 444 through a sliding rod. The outer surface of the pressure roller 444 is provided with a hard rubber sleeve 4441.
[0017] In this embodiment, the flexible backing strip is fed by the feeding roller 5 on the feeding mechanism 2. The flexible backing strip then passes through the guide roller 31 and the output roller 32 and through the square channel 42 into the processing equipment for feeding. During the feeding process, if the processing equipment connected to the square channel 42 experiences a jam, the pressure roller 444 remains in contact with the flexible backing strip. At this time, the tension of the output section of the flexible backing strip decreases, and the pressure sensing block 443 detects the pressure change, exceeding the warning value. At this time, the controller 7 receives the signal and controls the equipment to stop to achieve jam protection. Furthermore, the pressure of the pressure roller 444 on the flexible backing strip is adjusted by the adjusting screw 442 for different types of flexible backing strips, resulting in better adaptability. Thus, the device has the advantages of real-time detection and response to equipment jamming faults, reducing losses, and having a wide range of adaptability.
[0018] Furthermore, to address the issue that due to the inertia of equipment operation, even emergency shutdowns require time to stop, leading to uncontrollable losses, a second embodiment is proposed: Please see Figure 1 and Figure 3 The braking mechanism 6 includes a vertical cylinder 61 and a friction block 62. The vertical cylinder 61 is fixedly installed on the base 1, and the movable end of the vertical cylinder 61 is fixedly connected to the friction block 62. The friction block 62 is located at the bottom of the outer contour of the feeding roller 5.
[0019] In this embodiment, the vertical cylinder 61 is controlled by the controller 7 to drive the friction block 62 to contact the outer side of the feeding roller 5 instantly to achieve braking, thereby effectively reducing equipment inertia and reducing losses.
[0020] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
