Description

Technical Field

[0001] This application relates to the field of film capacitor manufacturing technology, and in particular to an industrial film capacitor winding device. Background Technology

[0002] Film capacitors are important electronic components, possessing advantages such as small size, large capacitance, and good stability, and are widely used in various fields such as electronics, power, and communications. In the production process of film capacitors, the winding process is one of the key steps, where the film is wound using a film capacitor winding device.

[0003] The thin-film capacitor winding machine mentioned in the existing Chinese patent (application publication number: CN120126952A) includes a tensioning component, which includes a main body assembly and tension components fixed to the upper and lower sides of the end face of the main body assembly. It also includes a track assembly fixed to the middle of the tension assembly and an expansion assembly rotating at the end of the track assembly. The expansion assembly and the tension assembly are adapted to each other, and the expansion assembly can drive the tension assembly to expand. The triggering component includes an intermittent component fixed to the main body assembly. Through the tensioning component, the triggering component, and the adjusting component, the present invention can provide tension for electrode rolls and thin-film rolls while having the function of automatically resetting the tension, and the required tension force can be preset.

[0004] When existing film capacitor winding devices are in operation, dust that adheres to the surface of the film during production or transportation will be wound along with the film. This dust will not only affect the insulation performance of the film capacitor but may also pose a potential threat to its structural stability, thereby reducing the overall quality and reliability of the product. Utility Model Content

[0005] The purpose of this application is to address the problem that in existing film capacitor winding devices, dust adheres to the surface of the film during production or transportation, and this dust is wound along with the film, which not only affects the insulation performance of the subsequent film capacitor but may also pose a potential threat to its structural stability. This application provides an industrial film capacitor winding device.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: An industrial thin-film capacitor winding device includes a main base, an mounting plate fixed to the upper end of the main base, a controller fixed to the side of the mounting plate, a thin film roll rotatably connected to the side of the mounting plate, a plurality of first tension rollers arranged on the side of the thin film roll, a plurality of second tension rollers mounted on the side of the first tension rollers, a plurality of third tension rollers mounted on the side of the second tension rollers, and a winding roller arranged on the side of the third tension rollers. The mounting plate is rotatably connected to the first tension rollers, second tension rollers, third tension rollers, and winding rollers. A winding motor for driving the winding roller to rotate is fixed on the side of the mounting plate away from the winding roller. The controller is electrically connected to the winding motor. A pressure roller and a cutting blade are mounted on the side of the mounting plate, and a dust collection structure is provided on the side of the mounting plate.

[0007] By adopting the above technical solution, during the winding process, the film roll is installed on the side of the mounting plate. The operator then manually pulls one end of the film, causing it to pass sequentially around the first, second, and third tension rollers, finally winding the film onto the winding roller. The winding motor and dust collection structure are then started. The winding motor drives the winding roller to rotate, and the rotation of the winding roller enables the winding operation of the film. During the winding process, the dust collection structure efficiently removes dust particles adhering to the film surface, effectively reducing the dust content in the middle of the film capacitor core and improving the overall quality and performance of the capacitor.

[0008] The dust collection structure includes two collection boxes installed on the side of the mounting plate, which are staggered vertically on the side of the mounting plate. A side plate is fixed to the side of each collection box, and multiple air outlets are provided on the side plate. A guide pipe is fixed to the side of each collection box away from the side plate, and a collection pipe is fixed to the end of the guide pipe away from the collection box. The end of the collection pipe is fixedly connected to the mounting plate, and the collection box is fixed to the side of the collection pipe. A collection component is provided inside the collection box.

[0009] By adopting the above technical solution, the amount of dust adhering to the film surface can be significantly reduced through the dust collection structure, thereby reducing the negative impact of dust on the performance of the film capacitor and effectively improving the overall quality of the subsequent film capacitor.

[0010] Furthermore, the collection component includes a mounting frame fixed to the side plate, a drive motor fixed inside the mounting frame, a controller electrically connected to the drive motor, an impeller fixed to the output end of the drive motor, a collection frame fixed inside the mounting frame, and a collection net fixed inside the collection frame.

[0011] By adopting the above technical solution, the drive motor drives the impeller to rotate, which generates negative pressure inside the collection box, thereby providing power for collecting dust.

[0012] Furthermore, an installation strip is installed inside the collection tube, and an anti-static brush is fixed at the lower end of the installation strip.

[0013] By adopting the above technical solution, the static electricity on the film surface can be eliminated by the antistatic brush, reducing the adhesion of dust on the film surface and making it easier for the collection tube to collect dust. Furthermore, an installation block is fixed inside the collection tube, and an electric telescopic rod is fixed at the lower end of the installation block. The controller is electrically connected to the electric telescopic rod, and the telescopic end of the electric telescopic rod is fixedly connected to the installation strip.

[0014] By adopting the above technical solution, the electric telescopic rod can be installed by moving the strip up and down, thereby adjusting the contact pressure between the antistatic brush and the film to adapt to films of different thicknesses and materials.

[0015] Furthermore, a corrugated hose is fixed to the lower end of the mounting block, and the lower end of the corrugated hose is fixedly connected to the mounting strip. The electric telescopic rod is located inside the corrugated hose.

[0016] By adopting the above technical solution, the corrugated hose can prevent dust and other impurities from entering the electric telescopic pole and affecting its normal operation.

[0017] Furthermore, a guide block is fixed inside the collection tube, and a guide post is fixed at the upper end of the mounting strip, with the guide post sliding through the guide block.

[0018] By adopting the above technical solution, the cooperation between the guide block and the guide post during the adjustment of the position of the antistatic brush makes the installation strip move more smoothly up and down.

[0019] Furthermore, an air velocity sensor is fixed inside the mounting frame, a buzzer is fixed at the upper end of the mounting plate, and the controller is electrically connected to both the air velocity sensor and the controller.

[0020] By adopting the above technical solution, the air velocity sensor detects the air velocity in the collection box. If it is lower than the preset threshold, it indicates that the negative pressure in the box is insufficient. At this time, the buzzer alarm is triggered to remind the staff to check the equipment and see if there are problems such as blockage of the collection net or failure of the drive motor, so as to ensure effective cleaning of dust on the membrane surface.

[0021] In summary, this application includes at least one of the following beneficial effects: 1. In this application, during the winding of the film, the impeller is driven by a drive motor to rotate, which generates a negative pressure inside the collection box. This causes dust on the upper and lower surfaces of the film to be drawn into the collection box, and the dust particles are intercepted by the collection mesh to achieve dust collection. By applying the dust collection structure, the amount of dust adhering to the film surface can be significantly reduced, thereby reducing the negative impact of dust on key performance aspects such as the insulation performance and structural stability of the film capacitor, and effectively improving the overall quality of the subsequent film capacitor.

[0022] 2. In this application, during the film conveying process, the antistatic brush can promptly eliminate static electricity on the film surface when it comes into contact with the film, thereby electrostatically adsorbing dust and further ensuring the cleanliness of the film surface. By eliminating static electricity, the adhesion of dust on the film surface can be reduced, making it easier for the collection tube to collect dust. Attached Figure Description

[0025] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0026] This application discloses an industrial thin-film capacitor winding device.

[0027] Reference Figure 1An industrial thin-film capacitor winding device includes a main base 1, an mounting plate 11 fixed to the upper end of the main base 1, a controller 12 fixed to the side of the mounting plate 11, a thin film roll 13 rotatably connected to the side of the mounting plate 11, a plurality of first tension rollers 14 arranged on the side of the thin film roll 13, a plurality of second tension rollers 15 mounted on the side of the first tension rollers 14, a plurality of third tension rollers 16 mounted on the side of the second tension rollers 15, and a winding roller 17 arranged on the side of the third tension rollers 16. The mounting plate 11 is rotatably connected to the first tension rollers 14, the second tension rollers 15, the third tension rollers 16, and the winding roller 17. A winding motor for driving the winding roller 17 to rotate is fixed on the side of the mounting plate 11 away from the winding roller 17. The controller 12 is electrically connected to the winding motor. A pressure roller 18 and a cutting blade 19 are mounted on the side of the mounting plate 11. A dust collection structure is provided on the side of the mounting plate 11.

[0028] In using this winding device, the film roll 13 is first installed on the side of the mounting plate 11. Next, the operator pulls one end of the film by hand, causing it to pass sequentially around the first tension roller 14, the second tension roller 15, and the third tension roller 16 in the device, finally winding the film onto the winding roller 17. The winding motor and dust collection structure are then started. When the winding motor starts working, it drives the winding roller 17 to rotate, thus achieving the winding operation of the film. Throughout the winding process, the dust collection structure also works synchronously, efficiently removing dust particles adhering to the film surface, thereby effectively reducing the dust content in the middle of the film capacitor core and further improving the overall quality and performance of the capacitor.

[0029] Reference Figure 2 and Figure 3 The dust collection structure includes two collection boxes 2 installed on the side of the mounting plate 11, which are staggered vertically on the side of the mounting plate 11. A side plate 21 is fixed to the side of the collection box 2, and multiple air outlet holes are opened on the side plate 21. A guide pipe 22 is fixed to the side of the collection box 2 away from the side plate 21. A collection pipe 23 is fixed to the end of the guide pipe 22 away from the collection box 2. The end of the collection pipe 23 is fixedly connected to the mounting plate 11. The collection box 2 is fixed to the side of the collection pipe 23. A collection component is provided inside the collection box 2.

[0030] The collection component includes a mounting frame 24 fixed on the side plate 21, a drive motor 241 fixed inside the mounting frame 24, a controller 12 electrically connected to the drive motor 241, an impeller 242 fixed at the output end of the drive motor 241, a collection frame 243 fixed inside the mounting frame 24, and a collection net 244 fixed inside the collection frame 243.

[0031] During the film winding process, the film passes between two staggered collection tubes 23. By activating the drive motor 241, the impeller 242 rotates, creating a negative pressure inside the collection box 2. Subsequently, under the action of the guide tube 22, a negative pressure is created at the location of the collection tubes 23, drawing dust from the upper and lower surfaces of the film into the collection box 2. After entering the collection box 2 with the airflow, the dust first passes through the collection net 244, which effectively intercepts dust particles, preventing them from continuing to flow with the airflow. The intercepted dust adheres to the collection net 244, thus achieving the collection of dust adhering to the film surface. The application of this dust collection structure significantly reduces the amount of dust adhering to the film surface, thereby reducing the negative impact of dust on key performance characteristics such as the insulation performance and structural stability of the film capacitor, effectively improving the overall quality of the subsequent film capacitor.

[0032] Reference Figure 4 and Figure 5 An installation strip 25 is installed inside the collection tube 23, and an anti-static brush 251 is fixed at the lower end of the installation strip 25.

[0033] The collection pipe 23 has an installation block 252 fixed inside, and an electric telescopic rod 253 is fixed at the lower end of the installation block 252. The controller 12 is electrically connected to the electric telescopic rod 253, and the telescopic end of the electric telescopic rod 253 is fixedly connected to the installation strip 25.

[0034] In addition, a corrugated hose 254 is fixed to the lower end of the mounting block 252. The lower end of the corrugated hose 254 is fixedly connected to the mounting strip 25, and the electric telescopic rod 253 is located inside the corrugated hose 254.

[0035] Furthermore, a guide block 255 is fixed inside the collection tube 23, and a guide post 256 is fixed at the upper end of the mounting strip 25, with the guide post 256 sliding through the guide block 255.

[0036] During film transport, the antistatic brush 251, upon contact with the film, promptly eliminates static electricity from the film surface, thereby electrostatically attracting dust and further ensuring the cleanliness of the film surface. By eliminating static electricity, the adhesion of dust to the film surface is reduced, making it easier for the collection tube 23 to collect dust. Simultaneously, the electric telescopic rod 253, under the control of the controller 12, can extend and retract, driving the mounting strip 25 up and down, thereby adjusting the contact pressure between the antistatic brush 251 and the film to adapt to films of different thicknesses and materials, ensuring a stable and reliable antistatic effect. The corrugated hose 254 protects the electric telescopic rod 253, preventing dust and other impurities from entering and affecting its normal operation. The cooperation of the guide block 255 and guide post 256 ensures smoother up-and-down movement of the mounting strip 25, preventing deviation and guaranteeing effective contact between the antistatic brush 251 and the film.

[0037] Reference Figure 1 and Figure 2 An air velocity sensor 3 is fixed inside the mounting frame 24, and a buzzer 4 is fixed on the upper end of the mounting plate 11. The controller 12 is electrically connected to both the air velocity sensor 3 and the controller 12.

[0038] During the process of collecting dust adhering to the surface of the film using negative pressure, the air velocity sensor 3 can detect the air velocity inside the collection box 2. When the detected air velocity is lower than the preset threshold, it indicates that the negative pressure inside the collection box 2 is insufficient. At this time, the air velocity sensor 3 will transmit a signal to the controller 12. After receiving the signal, the controller 12 will immediately control the buzzer 4 to sound an alarm, reminding the staff to check the equipment in time to see if there is a problem such as blockage of the collection net 244 or failure of the drive motor 241. This ensures that the dust collection structure can operate continuously and stably, ensures that the dust on the surface of the film can be effectively cleaned, and improves the production quality of the film capacitor.

[0039] Working principle: When using this winding device, the film roll 13 is first installed on the side of the mounting plate 11. Next, the operator pulls one end of the film by hand, causing it to pass sequentially around the first tension roller 14, the second tension roller 15, and the third tension roller 16 in the device, finally winding the film onto the winding roller 17. The winding motor, drive motor 241, and antistatic brush 251 are then started. When the winding motor starts working, it drives the winding roller 17 to rotate, thus achieving the film winding operation.

[0040] When the drive motor 241 operates, it drives the impeller 242 to rotate, creating a negative pressure inside the collection box 2. Then, under the action of the guide pipe 22, a negative pressure is created at the collection pipe 23, causing dust from the upper and lower surfaces of the film to be drawn into the collection box 2. After entering the collection box 2 with the airflow, the dust first passes through the collection net 244, which effectively intercepts dust particles, preventing them from continuing to flow with the airflow. The intercepted dust adheres to the collection net 244, thus achieving the collection of dust adhering to the film surface. The application of this dust collection structure significantly reduces the amount of dust adhering to the film surface, thereby reducing the negative impact of dust on key performance characteristics such as the insulation performance and structural stability of the film capacitor, effectively improving the overall quality of the subsequent film capacitor.

[0041] During the film transport process, the antistatic brush 251 comes into contact with the film and can eliminate static electricity on the film surface in time, thereby reducing the static adsorption of dust and further ensuring the cleanliness of the film surface. By eliminating static electricity, the adhesion of dust on the film surface can be reduced, making it easier for the collection tube 23 to collect dust.
