Description

Technical Field

[0001] This utility model relates to the field of capacitor processing technology, specifically to a precision thin film slitting device for capacitor processing. Background Technology

[0002] Film capacitors have become indispensable electronic components in the electronics industry, used as the dielectric in plastic films. They possess advantages such as non-polarity, high insulation resistance, excellent frequency characteristics, and very low dielectric loss. During film slitting, a suction device adheres the film to the cutting blade, effectively preventing slippage. Areas for improvement in film processing include: When processing films, which have good plasticity, toughness and strength, they are usually cut by a cutting blade. Because the surface of the film is relatively smooth, the blade is prone to slipping and deviating during cutting. In addition, if there is no effective support at the cutting point, the intervention of the cutting blade will cause the film to deform and loosen, resulting in the film blade being unable to cut the film and causing the film to be stretched, which reduces the cutting effect and product quality. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a precision thin film slitting device for capacitor processing, which solves the problem of slippage or deformation of the thin film during the cutting process.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a precision thin film slitting device for capacitor processing, comprising a base and connecting arms symmetrically mounted on the base, wherein clamping members for clamping the thin film to be cut are symmetrically mounted on the base, and an adjustable slitting device for acting on the thin film and adjusting the slitting spacing is installed between the clamping members. The base consists of a guide table and a cutting table, with the guide table being trapezoidal and docking with the cutting table. The clamping component includes a clamping plate a adapted to the slope of the guide table and a clamping plate b parallel to the cutting table. Adjusting ends for adjusting the height of the clamping component are symmetrically installed on the clamping plate b. The adjustable slitting device includes adjusting components mounted on two connecting arms. A suspension rod for suspending the cutter is installed between the front and rear symmetrical adjusting components. The suspension rod consists of a main rod and a secondary rod, and the main rod and the secondary rod are movably connected.

[0005] Preferably, both the main rod and the auxiliary rod are equipped with cutters.

The auxiliary rod is provided with a positioning groove, and a positioning post slides on the positioning groove. The diameter of the positioning post is adapted to the diameter of the fixing hole.

[0010] Compared with the prior art, the present invention provides a precision thin film slitting device for capacitor processing, which has the following advantages: In the technical solution disclosed in this utility model, the guide platform in the base and the adjustable slitting device work together to adjust the adjustable slitting device according to the slitting requirements on the basis of a flat film to be cut, thereby achieving a flat state to be cut on the basis of the film being in a predetermined position, thus generating a base surface that meets the predetermined slitting requirements.

Detailed Implementation

[0014] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0015] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] Figures 1-4 As an embodiment of this utility model, the specific problem addressed by this embodiment is that when processing films, because films have good plasticity, toughness and strength, they are usually cut by a cutting blade. However, because the surface of the film is relatively smooth, the blade is prone to slipping and deviating from the film surface during cutting. Furthermore, when there is no effective support at the cutting point, the intervention of the cutting blade will cause the film to deform and loosen, resulting in the film cutting blade being unable to cut the film and causing the film to be stretched, thus reducing the cutting effect and product quality. The applicant believes that it is necessary to adjust the film to a flat state when it comes into contact with the cutter, and that the film should always be taut during the slitting process. This can solve the above problems. In the technical solution disclosed in this application, the guide table 11 in the base 1 and the adjustable slitting device 4 are used in cooperation. On the basis of flat film to be cut, the adjustable slitting device 4 is adjusted according to the slitting requirements, so as to form a flat state to be cut on the basis of the film being in a predetermined position, thereby generating a base surface that meets the predetermined slitting requirements. Then, the height difference between the auxiliary rod 43 and the main rod 42 is adjusted, and the distance between the cutter 44 on the auxiliary rod 43 and the cutter 44 on the main rod 42 is adjusted, thereby generating film slices that meet the requirements.

[0017] Specifically, this is a precision film slitting device for capacitor processing, comprising a base 1 and connecting arms 2 symmetrically mounted on the base 1. The base 1 consists of a guide table 11 and a cutting table 12. The guide table 11 is trapezoidal and docks with the cutting table 12. The connecting arms 2 consist of a positioning plate 21 and a drive rod 22 mounted on the positioning plate 21. The drive rod 22 is rotatably mounted on the positioning plate 21, and a drive motor for driving its rotation is installed at the lower end of the rotating rod. The drive rod 22 is specifically a threaded rod. Two clamping members 3 are symmetrically mounted on the base 1 to clamp the film to be cut. An adjustable clamping device is installed between the clamping members 3 to act on the film and adjust the slitting distance. The slitting device 4, an adjustable slitting device 4, includes adjusting members 41 mounted on two connecting arms 2. A suspension rod for suspending the cutter 44 is installed between the front and rear symmetrical adjusting members 41. The base 1 does not have a cutting groove. When the cutter 44 descends to the point of contact with the film, the film is cut by the cutting action of the blade. The advantage of not having a cutting groove is that, on the one hand, it can reduce the film being pulled by the cutter 44 at the cutting position without the support of the cutting table 12 during the descent of the cutter 44, which would cause the film to be stretched due to tension, reduce the flatness of the film cut and the cutting effect. On the other hand, the cutting groove cannot effectively adapt to the change in the position of the cutter 44 on the auxiliary rod 43, resulting in the loss of the function of the cutting groove.

[0018] The clamping component 3 includes a clamping plate a31 adapted to the slope of the guide table 11 and a clamping plate b32 parallel to the cutting table 12. Adjusting end heads 33 for adjusting the height of the clamping component 3 are symmetrically installed on the clamping plate b32. The adjusting end heads 33 have threaded holes adapted to the drive rod 22 and are sleeved on the connecting arm 2. Both clamping plates a31 and b32 consist of end heads and connecting plates. The cross-section of the end heads is triangular. Several inner grooves are formed on the bottom surface of the connecting plate of clamping plate b32. The connecting plate and the end head act on the same plane between adjacent inner grooves. Above, the guide table 11 is placed on the left and right sides of the cutting table 12, and a take-up roller 13 is installed on it to release or take up the film. The take-up roller 13 is equipped with a drive motor to control its rotation. The film to be cut is placed on the take-up roller 13 in a whole roll, and then the film is guided to pass through the clamping member 3 and wound onto the take-up roller 13 at the other end. Then, the drive rod 22 that adjusts the height of the adjusting end 33 is opened and rotated to raise or lower the abutment plate a or abutment plate b. This reduces the possibility of positional changes or wrinkles when the film enters or leaves the cutting table 12.

[0019] The suspension rod consists of a main rod 42 and a secondary rod 43, which are movably connected. The installation position of the connecting arm 2 and the drive rod 22 is adapted to the position of the adjusting end 33 and the secondary rod 43. The connecting arm 2 drives the adjustable slitting device 4 and the clamping member 3 to adjust a certain distance, thereby adapting to the slitting of films of different thicknesses and the requirements of different clamping degrees. Both the main rod 42 and the secondary rod 43 are equipped with cutters 44. The secondary rod 43 is located at the front and rear ends of the main rod 42, and a groove for the cutter 44 to slide is opened on the secondary rod 43. The cutter 44 is installed on the slider, and the slider slides in the groove. The front and rear ends of the main rod 42 are provided with grooves for the secondary rod 43 to slide. A fixing hole 45 is opened in the groove. A positioning groove is opened on the secondary rod 43, and a positioning post 46 slides on the positioning groove. The diameter of the positioning post 46 is adapted to the diameter of the fixing hole 45. First, adjust the height of the cutter 44 on the auxiliary rod 43 relative to the film. After reaching the specified height, adjust the height of the main rod 42. If the cutting to the specified width does not require the participation of the main rod 42, the main rod 42 is suspended using the fixing hole 45 so that its cutter 44 cannot contact the film. Otherwise, adjust the main rod 42 and the cutter 44 to the same height. Then, adjust the cutter 44 on the auxiliary rod 43 according to the width so that it reaches the predetermined position. With the participation of the two take-up rollers 13, the film meets the cutter 44 during the winding process, and the cutting is completed.

The power supply is also common knowledge in the field.
