Technical Field

[0001] This utility model belongs to the field of capacitor stretching film production technology, and specifically relates to a bidirectional capacitor film stretching device. Background Technology

[0002] With the rapid development of flexible electronics, new energy storage devices and aerospace technology, the demand for high-performance capacitor film materials is increasing. As a key dielectric layer, the microstructure, orientation and interface properties of capacitor film directly affect the energy density, charge and discharge rate and cycle stability of the device.

[0003] The current announcement of Chinese utility model patent CN107756777B discloses a bidirectional high-efficiency stretching device for capacitor films. It is equipped with a worktable and a clamping seat. A set of parallel guide rods are installed on the upper surface of the worktable. The guide rods are directly connected to and pass through the hydraulic cylinder. Through bidirectional stretching action, the film is stretched uniformly in a symmetrical manner. The stretching on the plane is controlled as much as possible to achieve the purpose of uniform deformation stretching.

[0004] This patent describes stretching the capacitor stretching film at room temperature. At room temperature, the molecules of the capacitor stretching film have high thermal motion energy, and the material is prone to springback due to thermal vibration after stretching. Utility Model Content

[0005] The purpose of this invention is to provide a bidirectional capacitor film stretching device, which solves the problem that existing bidirectional high-efficiency stretching devices for capacitor films are used to stretch capacitor films at room temperature. At room temperature, the thermal motion energy of capacitor film molecules is high, and the material is prone to springback due to thermal vibration after stretching.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a bidirectional capacitor film stretching device, including a low-temperature environment chamber, a cooling mechanism in the low-temperature environment chamber, and a stretching mechanism in the low-temperature environment chamber.

[0007] The cooling mechanism includes an insulation cavity and a refrigerator. The insulation cavity is located on the inner wall of the low-temperature environment chamber. The outer wall of the insulation cavity is made of aluminum alloy heat dissipation material, and the inner wall of the insulation cavity is made of stainless steel. The insulation cavity is filled with nano-aerogel insulation material. The refrigerator is fixedly installed on the side wall of the low-temperature environment chamber, and the air outlet of the refrigerator extends into the interior of the low-temperature environment chamber.

[0008] Using the above technical solution, by setting up a low-temperature environment chamber, a cooling mechanism, and a stretching mechanism, in use, the low-temperature environment chamber and the cooling mechanism work together to provide a low-temperature environment for stretching the capacitor stretching film. Then, the stretching mechanism can stretch the capacitor stretching film. The cooling mechanism includes an insulation chamber and a refrigerator. The aluminum alloy outer wall of the heating chamber has good thermal conductivity, which can quickly disperse the heat transferred from the external environment to the outer wall of the insulation chamber and avoid local heat concentration. The nano-aerogel material has extremely low thermal conductivity, which can effectively block heat from entering the insulation chamber through heat conduction. The stainless steel inner wall provides structural strength and also acts as a radiation barrier to reduce heat transfer through heat radiation. Then, the cooling mechanism generates cold air through a refrigeration cycle and delivers the cold air to the low-temperature environment chamber through the air outlet.

[0009] Furthermore: the tensioning mechanism includes a mounting frame, a first gear, a second gear, a motor, a connecting rod, a fixing block, a through-hole, a cross plate, teeth, a gear rotating block, a fixing plate, and a clamping assembly. The mounting frame is fixedly installed inside the low-temperature environment chamber. The first gear is rotatably mounted on the side wall of the mounting frame. The second gear meshes with the first gear. The rotating shaft of the motor is fixedly mounted on the second gear. One end of the connecting rod is fixedly mounted on the first gear, and the other end of the connecting rod extends into the interior of the mounting frame and is rotatably connected to the inner wall of the mounting frame. The fixing blocks are fixedly installed on the inner wall of the mounting frame. There are two fixing blocks, which are symmetrically arranged. The through-hole is opened on the fixing block. The horizontal plate passes through the through-hole. The teeth are fixedly installed on the horizontal plate. There are several teeth, which are evenly arranged. The gear rotating block is fixedly installed on the connecting rod. There are two gear fixing blocks, which are symmetrically arranged. There are two sets of horizontal plates. Each set has two horizontal plates, which are connected to the gear rotating block through tooth meshing. The fixing plate is fixedly connected to one end of the horizontal plate. The clamping assembly is installed on the fixing plate.

[0010] Using the above technical solution, by setting up a mounting frame, a first gear, a second gear, a motor, a connecting rod, a fixing block, a through-hole, a horizontal plate, teeth, a gear rotating block, a fixing plate, and a clamping assembly, in use, the capacitor stretching film is first fixed in the clamping assembly, and then the motor drives the second gear to rotate, which in turn drives the first gear, the connecting rod, and the gear rotating block to rotate. Since the gear rotating block and the horizontal plate are connected by tooth meshing, the two sets of horizontal plates located above and below can move relative to each other, which in turn drives the fixing plate and the clamping assembly to move relative to each other, thereby stretching the capacitor stretching film. The fixing block can position the horizontal plate, and the through-hole allows the horizontal plate to pass through the fixing block and move.

[0011] Furthermore: the clamping assembly includes a movable groove, a movable rod, a clamping groove body, a threaded rod, a pressure plate, and a locking cap. The movable groove is formed on the fixed plate, the movable rod is movably disposed in the movable groove, the clamping groove body is fixedly disposed at one end of the movable rod, the threaded rod passes through the clamping groove body and is threadedly rotatably connected to the clamping groove body, the pressure plate is fixedly disposed at one end of the threaded rod located in the clamping groove body, and the locking cap is disposed at the end of the movable rod away from the clamping groove body.

[0012] Using the above technical solution, by setting up a moving groove, a moving rod, a clamping groove, a threaded rod, a pressure plate, and a locking cap, in practical use, the position of the moving rod is adjusted according to the width of the capacitor stretch film, so that the moving rod moves in the moving groove, and the four corners of the capacitor stretch film are placed in the clamping groove. Then, the threaded rod is rotated, so that the threaded rod drives the pressure plate to move, so that the pressure plate can fix the capacitor stretch film in the clamping groove. When the position of the moving rod is adjusted to the correct position, the moving rod is fixed to the fixing plate by the locking cap.

[0013] Furthermore: a temperature sensor is fixedly installed inside the low-temperature environment chamber, and a display is installed outside the low-temperature environment chamber, with the temperature sensor electrically connected to the display.

[0014] By adopting the above technical solution, and by setting a temperature sensor and a display, the temperature sensor can sense the temperature in the low-temperature environment chamber during use and transmit the temperature value to the display, so that the low-temperature environment chamber reaches the appropriate position before stretching.

[0015] Furthermore, a mounting plate is fixedly installed on the mounting frame, and the mounting plate is used to provide support for the motor.

[0016] By adopting the above technical solution, and by setting up a mounting plate, the mounting plate is fixed on the mounting frame during use, which can provide support for the motor and enable the motor to have a stable working environment.

[0017] Furthermore, a speed reducer is provided on the rotating shaft of the motor.

[0018] By adopting the above technical solution and setting a speed reducer, the speed reducer can reduce the speed of the motor during use, so as to avoid the motor speed being too fast and causing the electrothermal stretching film to be overstretched.

[0019] Furthermore, the low-temperature environment chamber is equipped with a movable door that rotates on it, and a handle is fixedly installed on the movable door.

[0020] By adopting the above technical solution, and by setting up a movable door and a handle, the movable door can be easily opened and closed in the low-temperature environment chamber during use, and the handle can provide a point of leverage for the staff.

[0021] Furthermore, the pressure plate is made of rubber.

[0022] By adopting the above technical solution, and by setting the material of the pressure plate, the pressure plate is made of rubber material during use, which can prevent the pressure plate from damaging the capacitor stretching film.

[0023] In summary, this utility model has the following beneficial effects:

[0024] By incorporating a cooling mechanism, the aluminum alloy outer wall of the heating chamber, with its excellent thermal conductivity, can quickly disperse the heat transferred from the external environment to the outer wall of the insulation chamber, preventing localized heat concentration. The nano-aerogel material has extremely low thermal conductivity, effectively blocking heat from entering the insulation chamber through thermal conduction. The stainless steel inner wall provides structural strength and also acts as a radiation barrier, reducing heat transfer through thermal radiation. The cooling mechanism then generates cooling capacity through a refrigeration cycle and delivers the cold air to the low-temperature environment chamber through the air outlet.

[0025] By setting up a stretching mechanism, during use, the capacitor stretching film is first fixed in the clamping assembly, and then the motor drives the second gear to rotate, which in turn drives the first gear, connecting rod, and gear rotating block to rotate. Since the gear rotating block and the horizontal plate are connected by tooth meshing, the two sets of horizontal plates located above and below can move relative to each other, which in turn drives the fixed plate and clamping assembly to move relative to each other, thereby stretching the capacitor stretching film. The fixed block can position the horizontal plate, and the through hole allows the horizontal plate to pass through the fixed block and move.

[0026] Based on the above improvements, the overall technical effect achieved by this device is to control the stretching environment of the capacitor stretching film in a low-temperature environment, reduce the heat loss of the low-temperature environment chamber, reduce the thermal motion energy of the capacitor stretching film molecules, and prevent the material from rebounding due to thermal vibration.

[0046] Brief description of usage:

[0047] In use, the aluminum alloy outer wall of the heating chamber is heated first. It has good thermal conductivity and can quickly disperse the heat transferred from the external environment to the outer wall of the insulation chamber 201, avoiding local heat concentration. The nano aerogel material has extremely low thermal conductivity and can effectively block heat from entering the insulation chamber 201 through heat conduction. The stainless steel inner wall provides structural strength and also acts as a radiation barrier to reduce heat transfer through heat radiation. Then, the cooling mechanism 2 generates cold energy through a refrigeration cycle and delivers the cold air to the low-temperature environment chamber 1 through the air outlet.

[0048] Then, the capacitor stretching film is fixed in the clamping assembly 312. The motor 304 drives the second gear 303 to rotate, which in turn drives the first gear 302, connecting rod 305, and gear rotating block 310 to rotate. Since the gear rotating block 310 is connected to the horizontal plate 308 by meshing teeth 309, the two sets of horizontal plates 308 located above and below can move relative to each other, thereby driving the fixing plate 311 and clamping assembly 312 to move relative to each other, thus stretching the capacitor stretching film. The fixing block 306 can position the horizontal plate 308, and the through-hole 30... 7. The horizontal plate 308 can pass through the fixed block 306 and move. The position of the moving rod 3122 is adjusted according to the width of the capacitor stretching film, so that the moving rod 3122 moves in the moving groove 3121. The four corners of the capacitor stretching film are placed in the clamping groove 3123. Then the threaded rod 3124 is rotated, so that the threaded rod 3124 drives the pressure plate 3125 to move, so that the pressure plate 3125 can fix the capacitor stretching film in the clamping groove 3123. When the position of the moving rod 3122 is adjusted to the correct position, the moving rod 3122 is fixed on the fixed plate 311 by the locking cap 3126.

[0049] Finally, the temperature sensor 4 can sense the temperature in the low-temperature environment chamber 1 and transmit the temperature value to the display 5, so that the low-temperature environment chamber 1 reaches the appropriate position before stretching. The mounting plate 7 is fixed on the mounting bracket 301 and can provide support for the motor 304, so that the motor 304 can have a stable working environment. The reducer 8 can reduce the speed of the motor 304 to avoid the motor 304 speed being too fast, which would cause the electrothermal stretching film to be overstretched.
