[0002] An aluminum electrolytic capacitor is a type of capacitor that uses an aluminum oxide film as the dielectric and an electrolyte as the cathode. Its key feature is that it can provide a very large capacitance per unit volume.

[0003] Currently, when using aluminum electrolytic capacitors, the leads on the capacitors are usually trimmed. However, the lead trimming machines for aluminum electrolytic capacitors are bulky, not suitable for personal use, and lack adjustment functions. If a different specification of aluminum electrolytic capacitor is replaced, there may be a situation where it cannot be adapted, affecting the quality of use. Summary of the Invention

[0005] This utility model is achieved through the following technical solution: an aluminum electrolytic capacitor lead cutting machine, comprising a crossbar and multiple capacitors to be cut, wherein the crossbar is provided with multiple connecting holes, and each connecting hole is equipped with an adjusting positioning component for positioning capacitors of different diameters. Each adjusting positioning component includes a column and a bottom shell, one end of each column is inserted into the connecting hole and narrows inward to form a connecting part, and the bottom shell is fitted over the outside of the connecting part. The end of the bottom shell away from the column is provided with a positioning channel for the leads of the capacitor to pass through. Each column is vertically provided with a mold cavity that penetrates the column and the connecting part. The capacitor is inserted into the mold cavity, and the bottom surface of the capacitor is placed in the bottom shell. The leads of the capacitor are set through the positioning channel. A support frame is installed on the outside of the crossbar, and a cutting mechanism is installed on the inside of the support frame.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model discloses an aluminum electrolytic capacitor lead cutting machine, including a crossbar 1 and multiple capacitors 4 to be cut. The crossbar 1 is provided with multiple connecting holes, and each connecting hole is equipped with an adjusting positioning component for positioning capacitors 4 of different diameters. Each adjusting positioning component includes a column 2 and a bottom shell 13. One end of each column 2 is inserted into the connecting hole and narrows inward to form a connecting part 17. The bottom shell 13 is fitted over the connecting part 17. The end of the bottom shell 13 away from the column 2 is provided with a positioning channel 14 for the leads of the capacitor 4 to pass through. Each column 2 is provided with a mold cavity 12 that penetrates the column 2 and the connecting part 17. The capacitor 4 is inserted into the mold cavity 12, and the bottom surface of each capacitor 4 is placed in the bottom shell 13. The leads of each capacitor 4 are set through the positioning channel 14. A support frame 7 is installed on the outside of the crossbar 1, and a cutting mechanism is installed on the inside of the support frame 7.

[0019] In this embodiment, the other end of each column 2 extends to the outside and expands outward to form a ring-shaped hand-held rotating part 3. The outer ring surface of the hand-held rotating part 3 is provided with anti-slip texture, the outer ring surface of each column 2 is provided with external threads, and the inner wall surface of the connecting hole is provided with internal threads. Each column 2 is connected by meshing with the internal threads on the connecting hole through the external threads. The threaded connection facilitates the installation and removal of the adjustment and positioning components.

[0020] In this embodiment, a positioning groove 5 is vertically provided on the inner wall surface of the connecting hole, and a positioning part 16 is protruding on the outer ring surface of the bottom shell 13. The positioning part 16 is slidably disposed in the positioning groove 5.

[0021] In this embodiment, a ring-shaped limiting groove 15 is provided on the inner ring surface inside the bottom shell 13, and a limiting ring 18 is installed on the outer ring surface of the connecting part 17. The limiting ring 18 is movably disposed in the limiting groove 15.

[0022] In this embodiment, the cutting mechanism includes a first cutting blade 11, a second cutting blade 8, and a plurality of electric push rods 10. The first cutting blade 11 is mounted on the inner side of the support frame 7, and the second cutting blade 8 is disposed on the outer side of the first cutting blade 11 and opposite to it. The pins on the capacitor 4 extend between the first cutting blade 11 and the second cutting blade 8. The two ends of the second cutting blade 8 are bent to form a fixing part 9. The electric push rods 10 are all mounted on the support frame 7, and the piston rods of the electric push rods 10 all pass through the support frame 7 and are all connected and fixed to the fixing part 9.

[0023] In this embodiment, the crossbar 1 is made of transparent plastic material, and a scale 6 is provided on one side of the crossbar 1, so that the bottom of the bottom shell can be seen through the crossbar, and the movement height of the bottom shell can be known in combination with the scale.

[0024] Working principle: According to the diameter of the capacitor 4 to be cut, select a suitable adjusting positioning component (composed of a column 2 and a base 13). Screw the threaded end of the column 2 into the corresponding connecting hole on the crossbar 1. It can be easily tightened or replaced by holding the rotating part 3. The connecting part 17 at the front end of the column 2 is inserted into the base 13, and the axial limiting connection between the base 13 and the column 2 is achieved through the cooperation of the limiting ring 18 and the limiting groove 15, while allowing the base 13 to rotate relative to the column. The positioning part 16 on the outside of the base 13 is embedded in the positioning groove 5 of the crossbar 1, so that the base 13 can only move axially along the positioning groove 5 when the column 2 rotates, and will not rotate with the column 2.

[0025] In use, the main body of the aluminum electrolytic capacitor 4 is inserted into the mold cavity 12 of the column 2, so that its bottom is placed in the bottom shell 13. The two leads of the capacitor pass through the positioning channel 14 of the bottom shell 13 to ensure that the leads of multiple sets of capacitors are neatly arranged under the constraint of the positioning channel 14 and extend into the cutting area between the first cutting blade 11 and the second cutting blade 8.

[0026] By rotating the column 2, the column 2 and the bottom shell 13 move up and down as a whole due to the screw drive. The up and down movement of the bottom shell 13 will drive the capacitor 4 and its pins to rise and fall synchronously, thereby adjusting the length of the pins extending out of the positioning channel 14 (i.e. the length to be cut). The operator can use the scale 6 on the side of the crossbar 1 to precisely control the consistency of the length of multiple capacitor pins.

[0027] Once all capacitors 4 are installed and the pin length is adjusted, the electric push rod 10 is activated. The piston rod of the electric push rod 10 pushes the second cutting blade 8 to move towards the fixed first cutting blade 11. The two blades work together to cut off the neatly arranged pins at once, achieving efficient and neat batch cutting.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
