[0002] Etched foil is a special type of aluminum foil, a dedicated material for capacitors. It is a material that has undergone electrochemical etching to achieve the technical specifications required for capacitor use. The technical performance of this material determines the basic technical specifications of the capacitor. Etched foil is a product made by electrochemically or chemically etching special high-purity aluminum foil to expand its surface area, and then electrochemically forming an oxide film on the surface.

[0003] A search revealed a publication (announcement) number: CN109940685A, which discloses a foil cutting device for etched foil used in aluminum electrolytic capacitors. The foil cutting machine includes a base, a power box fixedly connected to the upper surface of the base, and a motor plate fixedly provided at the bottom of the power box.

[0029] This utility model discloses an etching foil cutting device for high specific capacitance aluminum electrolytic capacitors.

[0030] Example 1

[0031] This utility model provides, for example Figure 1-5The device shown is a high-capacitance aluminum electrolytic capacitor etching foil cutting device, comprising a base 1, a U-shaped chamber 2 connected to one end of the top of the base 1, electric conveying wheel devices 3 fixedly connected to both ends of the U-shaped chamber 2, a guide rail chamber 4 fixedly connected to the top of the cavity of the U-shaped chamber 2, a laser cutting device 5 fixedly connected to both ends of the cavity of the guide rail chamber 4 via an adjustment structure, and a cooling mechanism fitted onto the outer wall of both ends of the laser cutting device 5; a first cutting support table 6 fixedly connected to the bottom of the cavity of the U-shaped chamber 2; and a [missing information - likely a device name or structure]. The second cutting table 7 has a connecting chamber 8 fixedly connected to the side wall of the U-shaped chamber 2. A first cylinder 9 is fixedly connected inside the cavity of the connecting chamber 8.

A clamping gripper 12 is fixedly connected inside the cavity of the transmission chamber 11 via a drive support mechanism. A second cylinder 13 is fixedly connected to the bottom of one end of the clamping gripper 12. One end of the second cylinder 13... The device is fixedly connected to a corresponding pressure plate 14 at each end, and the corresponding pressure plate 14 and the clamping gripper 12 are positioned accordingly. The etched foil is conveyed by electric conveying wheels 3 at both ends. The etched foil is trimmed on both sides during the conveying process by laser cutting devices 5 at both ends. The adjustable structure allows for easy adjustment of the spacing between the laser cutting devices 5 at both ends, facilitating the cutting of etched foil of different widths. The clamping gripper 12 is driven to move downwards and contact the etched foil by a drive support mechanism. The second cylinder 13 pushes the corresponding pressure plate 14 to merge with the clamping gripper 12, clamping the etched foil. The drive support mechanism moves downwards to pull the etched foil straight. The first cylinder 9 drives the cutting blade 10 to move downwards to cut the etched foil. This solves the problems of existing high-capacitance aluminum electrolytic capacitor etched foil cutting devices, which cannot freely adjust the two sides of the etched foil for cutting and trimming, and cannot straighten the etched foil, easily causing wrinkles and uneven cutting.

Threaded sleeves 17 are threadedly connected to the two ends of the bidirectional screw 15. The threaded sleeves 17 at both ends are fixedly connected to the top of the corresponding laser cutting device 5. The motor 16 drives the bidirectional screw 15 to rotate, thereby causing the threaded sleeves 17 at both ends of the bidirectional screw 15 to drive the corresponding laser cutting device 5 to move towards each other, thereby adjusting the distance between the two laser cutting devices.

Figure 1 , 2 As shown in Figure 4, the cooling mechanism includes a frame-shaped cooling spray plate 18, a cold air fan 19, and a connecting hose 20. The outer walls of both ends of the laser cutting device 5 are fitted with frame-shaped cooling spray plates 18. The top of the U-shaped chamber 2 is fixedly connected to the cold air fan 19.

[0036] Example 4

[0037] In order to move the clamping gripper 12, such as Figure 1 , 2 As shown in Figures 3 and 5, the drive support mechanism includes an electric push rod 21, a sliding opening 22, and a U-shaped support plate 23. The electric push rod 21 is fixedly connected to one end of the cavity of the transmission chamber 11. The sliding opening 22 is opened at the other end of the side wall of the transmission chamber 11, and the U-shaped support plate 23 is slidably connected thereto. One end of the electric push rod 21 is fixedly connected to the side wall of the U-shaped support plate 23. Both ends of the clamping gripper 12 are fixedly connected to the inner side walls of both ends of the U-shaped support plate 23. By using the electric push rod 21, the U-shaped support plate 23 is driven to slide in the sliding opening 22, thereby driving the clamping gripper 12 between the two ends of the U-shaped support plate 23 to move accordingly.

[0038] Example 5

[0039] For ease of use, such as Figure 1-5 As shown, the clamping gripper 12 is a trapezoidal plate with multiple positive grippers 24 fixedly connected to the bottom of the side wall, and the corresponding pressure plate 14 is a rectangular plate with multiple counter-pressure blocks 25 fixedly connected to the bottom. The top end of the second cutting table 7 is provided with multiple clamping notches 26 corresponding to the positions of the positive grippers 24. The frame-shaped cooling spray plate 18 is a frame-shaped hollow plate with multiple spray holes 27 at the bottom. The multiple positive grippers 24 are used to facilitate insertion into the corresponding clamping notches 26. The multiple counter-pressure blocks 25 descend to clamp the corrosion foil placed on the second cutting table 7. The frame-shaped cooling spray plate 18, which is a frame-shaped hollow plate with multiple spray holes 27 at the bottom, enables the frame-shaped cooling spray plate 18 to achieve the function of air cooling.

[0040] How to use:

[0041] In use, one end of the etched foil is placed into the U-shaped chamber 2, and the etched foil is pulled in by the electric conveyor wheel device 3 at one end. The etched foil is then transported by the electric conveyor wheel device 3 at the other end. Before transport, the etched foil is trimmed on both sides by the laser cutting devices 5 set at both ends. The clamping gripper 12 is driven by the drive support mechanism to move downwards. Multiple positive grippers 24 are inserted into the corresponding clamping notches 26 to contact the etched foil. Then, the second cylinder 13 pushes the corresponding pressure plate 14 to merge with the clamping gripper 12 to clamp the etched foil. The etched foil is pulled straight by the drive support mechanism to move downwards. The first cylinder 9 drives the cutting blade 10 to move downwards to cut the etched foil. When it is necessary to adjust the distance between the laser cutting devices 5 at both ends, the motor 16 drives the bidirectional screw 15 to rotate, so that the threaded sleeves 17 at both ends of the bidirectional screw 15 drive the corresponding laser cutting devices 5 to move towards each other, thereby adjusting the distance between the laser cutting devices at both ends.
