[0002] Capacitor film is an important material used in the manufacture of capacitors. It is usually made of polymer materials such as polyimide, polypropylene, and polyethylene terephthalate. It has good electrical insulation properties and reliable mechanical properties. It is mainly used in the manufacture of capacitors in electronic devices to store charge or regulate circuit voltage. The capacitor film is used as a dielectric layer in the capacitor, and its performance directly affects the key parameters of the capacitor such as capacitance, loss, withstand voltage and life.

[0015] Beneficial effects

[0016] This invention provides a bidirectional stretching traction device for capacitor films. Compared with the prior art, it has the following advantages:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a bidirectional stretching and traction device for capacitor film, comprising: a take-up and release component 1, which is used to install and limit the capacitor film to be stretched; a longitudinal stretching component 2, which is disposed on one side of the inner cavity of the take-up and release component 1 and is used to stretch the capacitor film longitudinally; and a transverse stretching component 3, which is disposed on one side of the longitudinal stretching component 2 and is used to stretch the capacitor film transversely.

[0026] When bidirectional stretching of the capacitor film is required, the take-up and release assembly 1 is first placed in a preset position, and then the longitudinal stretching assembly 2 is fixedly connected to one side of the inner cavity of the take-up and release assembly 1. This allows the take-up and release assembly 1 to provide support for the longitudinal stretching assembly 2, enabling the operator to place the capacitor film to be stretched on one side of the take-up and release assembly 1 so that the longitudinal stretching assembly 2 can stretch the capacitor film longitudinally. Since the longitudinal stretching assembly 2 is fixedly connected to one side of the transverse stretching assembly 3, and the bottom surface of the transverse stretching assembly 3 is connected to the inner cavity of the take-up and release assembly 1, the take-up and release assembly 1 can provide support for the transverse stretching assembly 3, enabling the transverse stretching assembly 3 to stretch the longitudinally stretched capacitor film laterally, thereby improving the performance of the capacitor film.

[0027] See Figure 1 , Figure 2 The take-up and take-down assembly 1 includes a workbench 11. An installation roller 12 is provided on one side of the top surface of the workbench 11. A first support plate 13 is provided at both ends of the installation roller 12. A take-up roller 14 is provided on the other side of the top surface of the workbench 11. A second support plate 15 is provided at both ends of the take-up roller 14. A drive motor 16 is provided at the upper position on one side surface of the second support plate 15.

[0028] The worktable 11 in the take-up and take-down assembly 1 can be placed in a preset position and can also provide support for the mounting roller 12. Since the mounting roller 12 is rotatably connected to the first support plate 13 at both ends, the worktable 11 can provide support for the first support plate 13, thereby allowing the mounting roller 12 to rotate between the first support plate 13 so that the capacitor film to be stretched can be placed on the mounting roller 12. Since the take-up roller 14 is fixedly connected to the other side of the top surface of the worktable 11, and the take-up roller 14 is movably connected to the second support plate 15 at both ends, and the drive motor 16 is rotatably connected to the upper part of one side surface of the second support plate 15, the worktable 11 can provide support for the second support plate 15, thereby allowing the output end of the drive motor 16 to drive the take-up roller 14 to rotate so that the take-up roller 14 can wind up the capacitor film.

[0029] See Figure 1 , Figure 3The longitudinal tensioning assembly 2 includes two upright plates 21, each positioned centrally on the top surface of the workbench 11. A lifting roller 22 is positioned centrally on opposite sides of the two upright plates 21. A heating roller 23 is positioned on one side of each lifting roller 22, and a guide roller 210 is positioned on the other side. Guide grooves 24 are provided centrally on both upright plates 21. Connecting plates 25 are provided at both ends of the lifting roller 22. Electric telescopic rods 26 are provided centrally on the bottom surfaces of both connecting plates 25. The inner diameter of the guide groove 24 (viewed from above) is the same as the outer diameter of the connecting plate 25 (viewed from above), and they are compatible. A first limiting plate 27 is provided on one side of each connecting plate 25. Multiple fixing holes 28 are provided on one side of each upright plate 21, located on both sides of the guide grooves 24, arranged in a linear array. Fixing bolts 29 are provided on both sides of the centrally positioned one side of each first limiting plate 27.

[0030] The vertical plate 21 in the longitudinal stretching assembly 2 can be fixedly connected to the center of the top surface of the workbench 11 and also provide an installation base for the lifting roller 22. Since a heating roller 23 is provided on one side of the lifting roller 22 and a guide roller 210 is provided on the other side, the guide roller 210 can stretch the capacitor film, thereby allowing the heating roller 23 to heat the stretched capacitor film. Since guide grooves 24 are provided in the center of both vertical plates 21 and connecting plates 25 are fixedly connected to both ends of the lifting roller 22, and electric telescopic rods 26 are fixedly connected to the center of the bottom surface of both connecting plates 25, the guide grooves 24 can guide the connecting plates 25, thereby allowing the output end of the electric telescopic rod 26 to extend and retract while driving the connecting plates 25 upward. The lifting roller 22 moves up and down, allowing the connecting plate 25 to move the lifting roller 22 up and down. This facilitates the adjustment of the height of the lifting roller 22 by the operator, enabling effective control of the film stretching and ensuring that the thickness and physical properties of the stretched film meet production requirements. Since the first limiting plate 27 is fixedly connected to one side of each of the two connecting plates 25, and multiple fixing holes 28 are opened on one side of each of the two upright plates 21 located on both sides of the guide groove 24, and fixing bolts 29 are fixedly connected to the two sides of the center position on one side of each of the two first limiting plates 27, one end of the fixing bolt 29 can be rotatably connected to the inner cavity of the fixing hole 28, thereby fixing the first limiting plate 27 to the connecting plate 25, thus improving the stability of the lifting roller 22.

[0031] See Figure 1 , Figure 4 , Figure 5The transverse stretching component 3 includes a support plate 31, which is disposed on one side of the upright plate 21. Rotary rollers 33 are disposed on both sides of the top surface of the support plate 31. Multiple rotary rollers 33 are disposed in a linear array. Second limiting plates 32 are disposed at the top and bottom of the multiple rotary rollers 33. Conveyor belts 34 are disposed on the multiple rotary rollers 33. A servo motor 35 is disposed at one end of one of the rotary rollers 33. Fixing plates 36 are disposed on both sides of the outer center position of the conveyor belt 34. Locking plates 37 are disposed on the opposite sides of the two fixing plates 36. Locking posts 38 are disposed on the opposite sides of the two locking plates 37. Multiple locking posts 38 are disposed in a linear array.

[0032] The support plate 31 in the transverse tensioning assembly 3 can be fixedly connected to one side of the vertical plate 21 and also provide an installation base for the rotating roller 33. Multiple rotating rollers 33 are rotatably connected, and each of the top and bottom ends of the multiple rotating rollers 33 is connected to a second limiting plate 32. Simultaneously, multiple rotating rollers 33 are rotatably connected to a conveyor belt 34, and one end of one rotating roller 33 is fixedly connected to a servo motor 35. This allows the second limiting plate 32 to limit the rotation of the rotating roller 33, thereby enabling the output end of the servo motor 35 to drive the rotating roller 33 to rotate, thus allowing the rotating roller 33 to drive the conveyor belt 34 to rotate. Since the outer center of the conveyor belt 34 is fixed on both sides... A fixed plate 36 is connected, and two fixed plates 36 are fixedly connected to each other on opposite sides with a locking plate 37. At the same time, two locking plates 37 are fixedly connected to each other on opposite sides with a locking post 38. Multiple locking posts 38 are provided, so that the conveyor belt 34 can drive the fixed plate 36 to rotate, which in turn drives the locking plate 37 to rotate, so that the locking plate 37 can drive the locking post 38 to rotate. Then, through the locking post 38, the locking post 38 can limit and fix the edge of the capacitor film, which in turn drives the capacitor film to rotate, so as to perform lateral stretching treatment on the capacitor film, thereby increasing the strength of the capacitor film.

[0033] During operation, when bidirectional stretching of the capacitor film is required, the take-up and release assembly 1 is first placed in a preset position, and then the longitudinal stretching assembly 2 is fixedly connected to one side of the inner cavity of the take-up and release assembly 1. This allows the take-up and release assembly 1 to provide support for the longitudinal stretching assembly 2, enabling the operator to place the capacitor film to be stretched on one side of the take-up and release assembly 1 so that the longitudinal stretching assembly 2 can stretch the capacitor film longitudinally. Since the longitudinal stretching assembly 2 is fixedly connected to one side of the transverse stretching assembly 3, and the bottom surface of the transverse stretching assembly 3 is connected to the inner cavity of the take-up and release assembly 1, the take-up and release assembly 1 can provide support for the transverse stretching assembly 3, enabling the transverse stretching assembly 3 to stretch the longitudinally stretched capacitor film laterally, thereby improving the performance of the capacitor film.

[0034] The worktable 11 in the take-up and take-down assembly 1 can be placed in a preset position and can also provide support for the mounting roller 12. Since the mounting roller 12 is rotatably connected to the first support plate 13 at both ends, the worktable 11 can provide support for the first support plate 13, thereby allowing the mounting roller 12 to rotate between the first support plate 13 so that the capacitor film to be stretched can be placed on the mounting roller 12. Since the take-up roller 14 is fixedly connected to the other side of the top surface of the worktable 11, and the take-up roller 14 is movably connected to the second support plate 15 at both ends, and the drive motor 16 is rotatably connected to the upper part of one side surface of the second support plate 15, the worktable 11 can provide support for the second support plate 15, thereby allowing the output end of the drive motor 16 to drive the take-up roller 14 to rotate so that the take-up roller 14 can wind up the capacitor film.

[0035] The vertical plate 21 in the longitudinal stretching assembly 2 can be fixedly connected to the center of the top surface of the workbench 11 and also provide an installation base for the lifting roller 22. Since a heating roller 23 is provided on one side of the lifting roller 22 and a guide roller 210 is provided on the other side, the guide roller 210 can stretch the capacitor film, thereby allowing the heating roller 23 to heat the stretched capacitor film. Since guide grooves 24 are provided in the center of both vertical plates 21 and connecting plates 25 are fixedly connected to both ends of the lifting roller 22, and electric telescopic rods 26 are fixedly connected to the center of the bottom surface of both connecting plates 25, the guide grooves 24 can guide the connecting plates 25, thereby allowing the output end of the electric telescopic rod 26 to extend and retract while driving the connecting plates 25 upward. The lifting roller 22 moves up and down, allowing the connecting plate 25 to move the lifting roller 22 up and down. This facilitates the adjustment of the height of the lifting roller 22 by the operator, enabling effective control of the film stretching and ensuring that the thickness and physical properties of the stretched film meet production requirements. Since the first limiting plate 27 is fixedly connected to one side of each of the two connecting plates 25, and multiple fixing holes 28 are opened on one side of each of the two upright plates 21 located on both sides of the guide groove 24, and fixing bolts 29 are fixedly connected to the two sides of the center position on one side of each of the two first limiting plates 27, one end of the fixing bolt 29 can be rotatably connected to the inner cavity of the fixing hole 28, thereby fixing the first limiting plate 27 to the connecting plate 25, thus improving the stability of the lifting roller 22.

[0036] The support plate 31 in the transverse tensioning assembly 3 can be fixedly connected to one side of the vertical plate 21 and also provide an installation base for the rotating roller 33. Multiple rotating rollers 33 are rotatably connected, and each of the top and bottom ends of the multiple rotating rollers 33 is connected to a second limiting plate 32. Simultaneously, multiple rotating rollers 33 are rotatably connected to a conveyor belt 34, and one end of one rotating roller 33 is fixedly connected to a servo motor 35. This allows the second limiting plate 32 to limit the rotation of the rotating roller 33, thereby enabling the output end of the servo motor 35 to drive the rotating roller 33 to rotate, thus allowing the rotating roller 33 to drive the conveyor belt 34 to rotate. Since the outer center of the conveyor belt 34 is fixed on both sides... A fixed plate 36 is connected, and two fixed plates 36 are fixedly connected to each other on opposite sides with a locking plate 37. At the same time, two locking plates 37 are fixedly connected to each other on opposite sides with a locking post 38. Multiple locking posts 38 are provided, so that the conveyor belt 34 can drive the fixed plate 36 to rotate, which in turn drives the locking plate 37 to rotate, so that the locking plate 37 can drive the locking post 38 to rotate. Then, through the locking post 38, the locking post 38 can limit and fix the edge of the capacitor film, which in turn drives the capacitor film to rotate, so as to perform lateral stretching treatment on the capacitor film, thereby increasing the strength of the capacitor film.

[0037] In summary, this device can both bidirectionally stretch and pull the capacitor film and adjust the position of the lifting rollers, thereby controlling the stretching ratio of the film during the stretching process and effectively controlling the degree of film stretching, so as to ensure that the thickness and physical properties of the film after stretching meet the production requirements.
