Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolytic capacitors, in particular to an ultra-high voltage corrosion foil winding machine for aluminum electrolytic capacitors. Background Art

[0002] Aluminum electrolytic capacitors are made of an aluminum cylinder as the negative electrode, filled with a liquid electrolyte, and a curved aluminum strip inserted as the positive electrode. They also need to be treated with a DC voltage to form an oxide film on the positive electrode as a dielectric. They are characterized by high capacity, but high leakage current, poor stability, and positive and negative polarity, making them suitable for power supply filtering or low-frequency circuits. To enable aluminum electrolytic capacitors to operate at higher voltages, ultra-high voltage (UHV) foil is often used as the electrode material due to its high energy density and high power density. In the prior art, the production of ultra-high voltage (UHV) foil for aluminum electrolytic capacitors often requires a winder to wind the foil. The foil end is secured to a take-up drum, which is then fixed to the winder and driven by the winder to rotate, thereby winding the foil. However, in actual use, the size of the foil varies depending on the application, resulting in different lengths and diameters of the take-up drum. Connecting the take-up drums of different sizes to the winder requires frequent adjustments by the operator, resulting in a long loading and unloading time for the winder. Utility Model Content

The four rotating plates 7 corresponding to the horizontal position are rotatably connected to a supporting plate 8 through a rotating shaft 2. The three supporting plates 8 are centered on the roller 3. The annular arrangement is such that when the distance between the fixed block 5 and the sliding block 6 in the same chute 4 decreases, the rotating plate 7 pushes the three expansion plates 8 to move synchronously and with the same amplitude away from the roller 3. The three expansion plates 8 cooperate to limit the ultra-high voltage corrosion foil reel. The roller 3 is then rotated to drive the reel to rotate, thereby reeling the ultra-high voltage corrosion foil for aluminum electrolytic capacitors. A single-chip microcomputer 10 is provided on the front surface of the housing 1. The input terminal of the single-chip microcomputer 10 is electrically connected to an external power supply to control the start and stop of the entire device.

[0023] Drive mechanism 9: It is arranged inside the housing 1. The drive mechanism 9 includes a motor 91, a gear 92 and an outer gear ring 93. The motor 91 is arranged inside the housing 1. A gear 92 is provided at the right end of the output shaft of the motor 91. The outer gear ring 93 is arranged on the outer arc surface of the roller 3. The outer gear ring 93 is meshed with the gear 92. The input end of the motor 91 is electrically connected to the output end of the single-chip microcomputer 10 to provide power for the rotation of the roller 3. The drive mechanism 9 also includes an electric push rod 94, an adjustment plate 95, a ring 96, an adjustment rod 97 and a spring 98. The adjustment rod 97 is located inside the roller 3. The central axis of the roller 3 is collinear with the central axis of the adjustment rod 97. The sliding block 6 The outer arc surface of the adjusting rod 97 is rotatably connected to the adjusting rod 97. The left end of the adjusting rod 97 passes through the interior of the roller 3. The outer arc surface of the adjusting rod 97 is rotatably connected to the ring 96. The electric push rod 94 is arranged inside the housing 1. The right end of the electric push rod 94 is provided with an adjusting plate 95. The upper end of the adjusting plate 95 is rotatably connected to the adjusting rod 97. A spring 98 is provided between the adjusting plate 95 and the ring 96. The spring 98 is movably sleeved on the outer arc surface of the adjusting rod 97. The input end of the electric push rod 94 is electrically connected to the output end of the single-chip microcomputer 10. When the electric push rod 94 is started, the telescopic end of the electric push rod 94 drives the adjusting plate 95 to move to the left, pushing the spring 98 to contract. Under the action of the lever 96, the ring 96 and the adjusting rod 97 are pushed to the left, and the sliding block 6 is pulled to slide to the left in the chute 4, so that the distance between the fixed block 5 and the sliding block 6 in the same chute 4 is reduced.

The greater the contraction amplitude of the spring 98, the greater the elastic force it generates, and the action applied by the expansion plate 8 to the ultra-high pressure corrosion foil winding drum is greater. The greater the force, the more secure the limit of the ultra-high voltage corrosion foil winding drum is. A baffle 11 is provided at the right end of the supporting plate 8. The outer arc surface of the roller 3 is laterally slidably connected to the limit disk 12. The upper end of the shell 1 is respectively provided with an adjusting push rod 14.

[0024] The working principle of the ultra-high voltage corrosion foil winding machine for aluminum electrolytic capacitors provided by the present invention is as follows: in the process of producing ultra-high voltage corrosion foil for aluminum electrolytic capacitors, the winding drum is sleeved on the outer arc surface of the whole composed of three supporting plates 8, the end of the ultra-high voltage corrosion foil is fixed to the winding drum, and then the electric push rod 94 is started by the single-chip microcomputer 10. The telescopic end of the electric push rod 94 drives the adjustment plate 95 to move to the left, pushing the spring 98 to contract. Under the elastic force of the spring 98, the ring 96 and the adjustment rod 97 are pushed to move to the left, pulling the sliding block 6 to slide to the left in the slide groove 4. The distance between the fixed block 5 and the sliding block 6 in the same slide groove 4 is reduced. Under the rotation connection of the rotating plate 7, the three supporting plates 8 are pushed to move synchronously and with the same amplitude in the direction away from the roller 3. The cooperation of the three supporting plates 8 is used to limit the ultra-high voltage corrosion foil winding drum, and the distance between the adjustment plate 95 and the ring 96 is measured by the distance measuring sensor 99. The spacing is detected to determine the contraction amplitude of the spring 98. The greater the contraction amplitude of the spring 98, the greater the elastic force it generates, and the greater the force exerted by the expansion plate 8 on the ultra-high voltage corrosion foil winding drum, making the limit of the ultra-high voltage corrosion foil winding drum more secure. At the same time, the adjustment push rod 14 is started, and the telescopic end of the adjustment push rod 14 pushes the connecting plate 13 and the limit plate 12 to move to the right. Through the cooperation of the limit plate 12 and the baffle 11, the left and right positions of the ultra-high voltage corrosion foil winding drum are restricted, and winding drums of different sizes are automatically fixed. Then the motor 91 is started, and the output shaft of the motor 91 drives the gear 92 to rotate. Through the meshing connection between the gear 92 and the outer gear ring 93, the outer gear ring 93 and the roller 3 are driven to rotate. The adjusting rod 97 rotates relative to the adjusting plate 95 and the ring 96. The limit plate 12 rotates in the U-shaped rotating groove of the connecting plate 13, and the ultra-high voltage corrosion foil for the aluminum electrolytic capacitor is wound on the surface of the winding drum.
