Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolytic capacitor winding fixture technology, and in particular to a precision control fixture for aluminum electrolytic capacitor winding. Background Technology

[0002] Aluminum electrolytic capacitors are polar electrolytic capacitors with aluminum metal as the anode, aluminum oxide as the dielectric layer, and electrolyte as the cathode. They are widely used in power supply filtering, signal coupling, energy storage, and other fields. In the production process of aluminum electrolytic capacitors, winding fixtures are usually used to precisely control the winding tension, alignment, and interlayer consistency to ensure the stability and reliability of the capacitor performance.

[0003] In existing winding fixtures for aluminum foil or electrolytic paper used in aluminum electrolytic capacitors, guide wheels are usually provided on both sides of the aluminum foil or electrolytic paper to align and guide the aluminum foil or electrolytic paper during winding.

[0004] However, when aluminum foil or electrolytic paper comes into contact with and moves relative to the surface of the guide wheel, friction is easily generated. As the winding work continues, the surface of the guide wheel is easily worn and small particles are generated. These small particles can then adhere to the aluminum foil or electrolytic paper, thus affecting the precise control of the winding of the aluminum electrolytic capacitor. Utility Model Content

[0005] Therefore, it is necessary to provide a precision control fixture for winding aluminum electrolytic capacitors to address the problem that fine particles can easily adhere to aluminum foil or electrolytic paper during wear.

[0006] The device includes: a base, the top of which is provided with a winding mounting bracket, and a fixed frame is fixedly connected to the top of the base; a dust extraction mechanism, which includes movable blocks on both sides of the fixed frame, guide wheels rotatably connected to the inner walls of the movable blocks, a first motor fixedly connected to the top of the movable blocks, the output shaft of the first motor fixedly connected to the top of the guide wheels, a dust collection frame fixedly connected to the top of the base, an exhaust fan fixedly connected to the inner bottom wall of the dust collection frame, a dust collection hose fixedly connected to the inner top wall of the dust collection frame, and a filter drawer slidably connected to the inner wall of the dust collection frame.

[0007] In one embodiment, a screw is rotatably connected to one side of the movable block, and the surface of the screw is threaded to the inner wall of the fixed frame.

[0008] In one embodiment, a measuring ruler is fixedly connected to one side of the movable block, and the surface of the measuring ruler is slidably connected to the inner wall of the fixed frame.

[0009] In one embodiment, a rubber spring is fixedly connected to one side of the movable block, and the other end of the rubber spring is fixedly connected to one side of the fixing frame.

[0010] In one embodiment, a silicone ring is fixedly connected to the inner wall of the dust collection frame, and the surface of the filter drawer abuts against the surface of the silicone ring.

[0011] In one embodiment, a counterweight is slidably connected to the inner wall of the vacuum cleaner frame, and the surface of the counterweight abuts against the surface of the filter drawer.

[0012] In one embodiment, a silicone pad is fixedly connected to the surface of the dust collection frame, with the bottom of the silicone pad abutting against the top of the counterweight. Through the cooperation of the silicone ring, the counterweight, and the silicone pad, the filter drawer is stably installed inside the dust collection frame, thereby ensuring the filter drawer's effectiveness in intercepting fine particles.

[0013] In one embodiment, the surface of the vacuum hose is fixedly connected to the inner wall of the movable block.

[0014] Beneficial effects

[0015] 1. The guide wheel is driven to rotate by the first motor, which avoids local wear on the guide wheel and reduces the generation of fine particles on the surface of the guide wheel. The fine particles attached to the surface of the guide wheel are extracted by the cooperation of the exhaust fan, dust collection frame and dust collection hose, which ensures the cleanliness of the guide wheel surface and prevents fine particles from adhering to the aluminum foil or electrolytic paper, thus ensuring precise control of the winding of aluminum electrolytic capacitors.

[0016] 2. By cooperating with the rubber spring, screw and measuring ruler, the lateral position of the guide wheel can be precisely adjusted, thereby ensuring that the surface of the guide wheel makes constant pressure contact with the side of the aluminum foil or electrolytic paper, reducing wear on the surface of the guide wheel, thereby reducing the adhesion of fine particles to the aluminum foil or electrolytic paper, and ensuring precise control of the winding of the aluminum electrolytic capacitor.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The following is combined Figures 1-5 This invention describes a precision control fixture for winding aluminum electrolytic capacitors.

[0027] In one embodiment, a precision control fixture for winding aluminum electrolytic capacitors includes: a base 100, a winding mounting bracket 300 on the top of the base 100, and a fixing bracket 200 fixedly connected to the top of the base 100; a dust extraction mechanism 400, including movable blocks 401 on both sides of the fixing bracket 200, guide wheels 402 rotatably connected to the inner wall of the movable blocks 401, a first motor 412 fixedly connected to the top of the movable blocks 401, the output shaft of the first motor 412 fixedly connected to the top of the guide wheels 402, a dust collection frame 403 fixedly connected to the top of the base 100, an exhaust fan 404 fixedly connected to the inner bottom wall of the dust collection frame 403, a dust collection hose 406 fixedly connected to the inner top wall of the dust collection frame 403, a filter drawer 405 slidably connected to the inner wall of the dust collection frame 403, and the surface of the dust collection hose 406 fixedly connected to the inner wall of the movable blocks 401.

[0028] It should be noted that: the winding mounting bracket 300 includes a bracket fixedly connected to the top of the base 100, a sliding bracket slidably connected to the inner wall of the bracket, a bolt threadedly connected to the inner wall of the bracket, the surface of the bolt threadedly connected to the inner wall of the sliding bracket, limit rods threadedly connected to the inner walls of both the bracket and the sliding bracket, a second motor fixedly connected to one side of the bracket, the output shaft of the second motor fixedly connected to one end of one of the limit rods, and a tension controller installed at one end of the other limit rod.

[0029] The inner wall of the fixed frame 200 is rotatably connected to a first limiting wheel, the top of the fixed frame 200 is fixedly connected to an electric push rod, the telescopic end of the electric push rod passes through the fixed frame 200 and is fixedly connected to a limiting frame, the surface of the limiting frame is slidably connected to the inner wall of the fixed frame 200, and the inner wall of the limiting frame is rotatably connected to a second limiting wheel.

[0030] The guide wheel 402 is made of polytetrafluoroethylene and has excellent smoothness, which can significantly reduce friction and reduce wear on the material and itself when guiding aluminum foil or electrolytic paper.

[0031] In this embodiment, when the aluminum foil and electrolytic paper used for aluminum electrolytic capacitors need to be wound, the unwinding mechanism is installed on the side of the base 100 near the dust collection frame 403, and the take-up roller is installed on the winding mounting frame 300. The distance between the second limit wheel and the first limit wheel is adjusted by the electric push rod so that the second limit wheel presses evenly on the material. The unwinding mechanism releases the aluminum foil and electrolytic paper according to the set tension. The aluminum foil and electrolytic paper are guided and installed on the take-up roller by the guide wheel 402, the first limit wheel and the second limit wheel. The limit rod and the take-up roller are driven to rotate by the second motor. The rotating take-up roller winds the material.

[0032] During the winding process, the first motor 412 and the exhaust fan 404 are manually turned on. The output shaft of the first motor 412 rotates, driving the guide wheel 402 to rotate. The rotating guide wheel 402 guides and limits the side of the moving material, preventing severe local wear on the surface of the guide wheel 402. The exhaust fan 404 draws air from the dust collection frame 403, creating a negative pressure inside the dust collection frame 403. This causes the dust collection hose 406 to draw out fine particles from the guide wheel 402 and transport them into the dust collection frame 403. The filter drawer 405 intercepts fine particles in the air, allowing the filtered air to be discharged through the exhaust fan 404. The tension controller monitors and adjusts the tension of the material in real time to ensure constant tension and the accuracy of the winding process.

[0033] like Figure 4As shown, a screw 407 is rotatably connected to one side of the movable block 401, and the surface of the screw 407 is threadedly connected to the inner wall of the fixed frame 200. A measuring ruler 408 is fixedly connected to one side of the movable block 401, and the surface of the measuring ruler 408 is slidably connected to the inner wall of the fixed frame 200. A rubber spring 409 is fixedly connected to one side of the movable block 401, and the other end of the rubber spring 409 is fixedly connected to one side of the fixed frame 200.

[0034] In this embodiment, when the lateral position of the guide wheel 402 needs to be adjusted, the screw 407 is rotated according to the width of the material. The screw 407 moves threadedly within the fixed frame 200 and drives the movable block 401 and the measuring ruler 408 to move laterally. The rubber spring 409 increases the resistance to the lateral movement of the movable block 401, allowing the movable block 401 to move laterally smoothly. By observing the specific distance that the measuring ruler 408 moves laterally within the fixed frame 200, the guide wheel 402 is precisely moved to the appropriate position, thereby applying pressure and limiting to the side of the material.

[0035] like Figure 3 As shown, a silicone ring 413 is fixedly connected to the inner wall of the dust collection frame 403, the surface of the filter drawer 405 abuts against the surface of the silicone ring 413, a counterweight 410 is slidably connected to the inner wall of the dust collection frame 403, the surface of the counterweight 410 abuts against the surface of the filter drawer 405, and a silicone pad 411 is fixedly connected to the surface of the dust collection frame 403, the bottom of the silicone pad 411 abuts against the top of the counterweight 410.

[0036] In this embodiment, when the filter drawer 405 needs to be cleaned, manually turn off the exhaust fan 404, flip the two silicone pads 411 so that the bottom of the silicone pads 411 is away from the top of the counterweight 410, pull the counterweight 410 upward to release the restriction on the filter drawer 405, and pull the filter drawer 405 away from the dust collection frame 403 to clean the filter drawer 405. After cleaning, install the filter drawer 405 in the dust collection frame 403.

[0037] Working principle: The output shaft of the first motor 412 rotates, driving the guide wheel 402 to rotate. The rotating guide wheel 402 guides and limits the side of the moving material. The exhaust fan 404 draws air from the dust collection frame 403, creating a negative pressure inside the dust collection frame 403. This causes the suction hose 406 to draw fine particles from the guide wheel 402 and transport them into the dust collection frame 403. The filter drawer 405 intercepts the fine particles in the air, allowing the filtered air to be discharged through the exhaust fan 404.

[0038] It should be noted that the base 100, fixing frame 200, winding mounting frame 300, guide wheel 402, exhaust fan 404, counterweight 410, first motor 412, tension controller, first limit wheel, second limit wheel, electric push rod and second motor mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the exhaust fan 404, first motor 412, tension controller, electric push rod and second motor can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
