Description
Technical Field
[0001] The utility model relates to the technical field of capacitor manufacturing, in particular to a capacitor winding device with a tension adjustment and deviation correction function. Background Technique
[0002] An aluminum electrolytic capacitor is a capacitor made of an aluminum cylinder as the negative electrode, filled with a liquid electrolyte inside, and inserted with a bent aluminum strip as the positive electrode. It is a general-purpose electrolytic capacitor made of aluminum material with good electrical performance, wide application range, and high reliability. Aluminum foil winding is an important step in the production process of aluminum electrolytic capacitors. The quality of aluminum foil winding will directly affect the production quality of aluminum electrolytic capacitors. When the aluminum foil is wound with deviation, if it is not corrected in time, it will cause the two ends of the produced capacitor to be inconsistent, easily resulting in capacitor failures. The deviation correction device of the existing capacitor winding device, such as an aluminum foil winding deviation correction device for aluminum electrolytic capacitors with the publication number CN115763083B, includes a frame. Two driving rollers are installed on the frame at left and right intervals. A plurality of conductive tape groups are embedded on the driving rollers. Each conductive tape group includes a first conductive tape and a second conductive tape. Each first conductive tape is arranged at one end of the driving roller at intervals along the axial direction, and each second conductive tape is arranged at the other end of the driving roller at intervals along the axial direction. One side edge of the aluminum foil is placed between two adjacent first conductive tapes, and the other side edge of the aluminum foil is placed between two adjacent second conductive tapes.

Therefore, we propose a capacitor winding device with a tension adjustment and deviation correction function to solve the problems raised above. Content of the Utility Model

The output end of the first reduction gear is installed with a transmission shaft, and the upper end of the transmission shaft penetrates and extends to the upper end of the bearing table and is installed with a guiding and deviation correction mechanism. An offset detection mechanism is installed on the second mounting plate.
[0006] Preferably, the guiding and deviation correction mechanism includes a rectangular frame. Below the inside of the rectangular frame, a lower roller shaft is installed, and both ends of the lower roller shaft are rotatably connected to the rectangular frame.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] (1) When the present utility model is normally winding, the aluminum foil tape is located on the surface of the upper pressure roller of the guiding and deviation correcting mechanism, and the upper roller frame extends under the action of the hydraulic cylinder, so that it contacts the upper surface of the aluminum foil on the upper pressure roller, playing the role of guiding and applying pressure, and to a certain extent avoiding the deviation of the aluminum foil. During the process, the deviation detection mechanism can detect the position state of the capacitor in real time. It is arranged at the front end of the guiding and deviation correcting mechanism, and the position of the aluminum foil is detected by two laser sensors distributed on both sides of the aluminum foil tape. Under normal conditions, the laser beams emitted by the laser sensors are unobstructed, which means that no deviation has occurred at this time. When the aluminum foil tape deviates to one side, it will touch and cover the laser beam emitted by one side of the laser sensor, which means that the aluminum foil tape deviates to the side of the blocked sensor at this time. Under the signal feedback of the sensor, the controller drives the hydraulic cylinder to move up, stops the upper pressure roller from applying pressure, and the servo motor in the tension adjustment base controls the guiding and deviation correcting mechanism to deflect in the direction of the other side of the deviation, and the deflection angle does not exceed ten degrees. At this time, the tension on the contact surface between the aluminum foil and the lower roller shaft changes, and the friction on one side is greater than that on the other side, so it deviates and resets to the side with greater friction, achieving the deviation correction effect. After the deviation correction is completed, the guiding and deviation correcting mechanism and the hydraulic cylinder are reset, and the aluminum foil tape is guided again. The whole process does not require shutdown operation, solving the problem that the existing device needs to stop operation for deviation correction during use, which affects the processing efficiency.
[0014] (2) The laser sensor of the present utility model is an adjustable structure. It is installed on the sliders of the forward lead screw and the reverse lead screw of the guide rail. By driving the forward lead screw and the reverse lead screw to rotate by the stepping motor, the laser sensors on both sides can be driven to move towards each other, so as to adjust the detection distance according to aluminum foil tapes of different width specifications, improving the versatility.

[0023] Please refer to Figures 1-6, an embodiment provided by the present utility model: a capacitor winding device based on tension adjustment and deviation correction function, comprising a bearing substrate 1. On one side of the front end of the bearing substrate 1, a tension adjustment base 2 is provided. On the other side of the front end of the bearing substrate 1, a winding mechanism 5 is installed. On one side of the rear end of the bearing substrate 1, a driving mechanism 6 is installed, and the output end of the driving mechanism 6 is in transmission connection with the winding mechanism 5. The tension adjustment base 2 includes a bearing table 201, a first mounting plate 203, a second mounting plate 204, a first reduction gear 206 and a servo motor 207. The first mounting plate 203 and the second mounting plate 204 are respectively installed on both sides of the bearing table 201, and mounting holes are provided at the rear ends of the first mounting plate 203 and the second mounting plate 204 for connecting with the bearing substrate 1 through bolts. A reinforcing plate 205 is installed inside the first mounting plate 203. The first reduction gear 206 is installed at the lower end of the bearing table 201. The output end of the servo motor 207 is in transmission connection with the input end of the first reduction gear 206. A transmission shaft 308 is installed at the output end of the first reduction gear 206. The upper end of the transmission shaft 308 penetrates and extends to the upper end of the bearing table 201, and a guiding and deviation correction mechanism 3 is installed. A deviation detection mechanism 4 is installed on the second mounting plate 204. The guiding and deviation correction mechanism 3 includes a rectangular frame 301. A lower roller shaft 302 is installed below the inside of the rectangular frame 301, and both ends of the lower roller shaft 302 are rotatably connected to the rectangular frame 301. A hydraulic cylinder 303 is installed at the upper end of the rectangular frame 301. The output end of the hydraulic cylinder 303 penetrates and extends to the inside of the rectangular frame 301, and an upper roller frame 304 is installed. An upper pressure roller 305 is installed inside the upper roller frame 304, and both ends of the upper pressure roller 305 are rotatably connected to the upper roller frame 304. The deviation detection mechanism 4 includes a guide rail seat 401. A forward lead screw 402 and a reverse lead screw 403 are installed inside the guide rail seat 401. One end of the reverse lead screw 403 is fixedly connected to the forward lead screw 402, and a central bearing piece 404 is installed at the connection of the forward lead screw 402 and the reverse lead screw 403. A stepping motor 407 is installed at the end of the guide rail seat 401. The other end of the reverse lead screw 403 penetrates and extends to the outside of the guide rail seat 401 and is in transmission connection with the output end of the stepping motor 407. Sliders 405 are installed on both the forward lead screw 402 and the reverse lead screw 403. A laser sensor 406 is installed at the upper end of the slider 405. The laser sensor 406 is connected to the slider 405 through a mounting piece and screws;During production, the aluminum foil coil is loaded into the unwinder. The unwinder operates driven by a motor, and the rotating unwinding shaft releases the aluminum foil strip. The released aluminum foil strip extends into the winding mechanism 5 after being processed and passes through the guiding and deviation-correcting mechanism 3. Under the transmission of the driving mechanism 6, the winding shaft 502 in the winding mechanism 5 rotates to realize the winding work of the capacitor aluminum foil. During normal winding, the aluminum foil strip is located on the surface of the upper pressure roller 305 of the guiding and deviation-correcting mechanism 3, and the upper roller frame 304 extends under the action of the hydraulic cylinder 303, so that it contacts the upper surface of the aluminum foil of the upper pressure roller 305, achieving the effect of guiding and applying pressure, and to a certain extent avoiding the deviation of the aluminum foil. During the process, the deviation detection mechanism 4 can detect the position state of the capacitor in real time. It is arranged at the front end of the guiding and deviation-correcting mechanism 3, and the positions of the aluminum foil are detected by two laser sensors 406 distributed on both sides of the aluminum foil strip. Under normal conditions, the laser beams emitted by the laser sensors 406 are unobstructed, which means that no deviation has occurred at this time. When the aluminum foil strip deviates to one side, it will touch and cover the laser beam emitted by one side of the laser sensor 406, which means that the aluminum foil strip deviates to the side of the blocked sensor at this time. After the laser sensor 406 is blocked, it feeds back a signal to the controller, and the controller drives the hydraulic cylinder 303 to move upward to stop the pressure application of the upper pressure roller 305. The servo motor 207 in the tension adjustment base 2 controls the guiding and deviation-correcting mechanism 3 to deflect in the direction of the other side of the deviation, and the deflection angle does not exceed ten degrees. At this time, the tension on the contact surface between the aluminum foil and the lower roller shaft 302 changes, and the friction force on one side is greater than that on the other side, so it deviates and resets to the side with the greater friction force to achieve the deviation-correcting effect. After the deviation correction is completed, the guiding and deviation-correcting mechanism 3 and the hydraulic cylinder 303 are reset to re-guide the aluminum foil strip. The whole process does not require shutdown operation; the laser sensor 406 is an adjustable structure. It is installed on the sliders 405 of the forward screw rod 402 and the reverse screw rod 403 of the guide rail. By driving the forward screw rod 402 and the reverse screw rod 403 to rotate by the stepping motor 407, the laser sensors 406 on both sides can be driven to move towards each other, so as to adjust the detection distance according to aluminum foil strips of different width specifications and improve the versatility.
