[0016] To further understand this utility model, preferred embodiments of this utility model are described below in conjunction with the accompanying drawings and examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the scope of the utility model claims.

[0017] The present invention discloses a terminal lead cutting mechanism that enables simultaneous cutting of multiple inductor component leads. Its structure is as follows: Figs. 1-3 As shown, the device includes a base 1, a support frame 2, a lower cutting blade 3, an upper cutting blade 4, a cylinder 5, an elastic bracket 6, and an upper pressure block 7. The support frame is fixed to one side of the upper surface of the base, and the lower cutting blade and the elastic bracket are fixed to the other side of the upper surface of the base. The elastic bracket is located on the side of the lower cutting blade. The upper pressure block is fixed to the side of the support frame with the sliding assembly 8. The cylinder is fixed to the top of the support frame with the mounting plate 9. The telescopic end of the cylinder is connected to the upper end of the upper pressure block. The upper cutting blade is fixed to the lower end face of the upper pressure block. The upper cutting blade and the lower cutting blade are arranged opposite to each other, and the elastic bracket is located directly below the upper pressure block.

[0018] During cutting, multiple inductor components are placed side by side on the elastic bracket. As the cylinder extends, the upper pressure block moves down to press the inductor components. At this time, the lower edge of the upper cutter is in contact with the pin. As the cylinder continues to extend, the upper pressure block, the upper cutter, and the elastic bracket continue to move down. The upper cutter and the lower cutter work together to cut the terminal.

[0019] Specifically, the base has two overall structures: fixed and adjustable. When the cutting mechanism is used alone, a fixed base can be used. When the cutting mechanism is used in conjunction with an automated production line, the base adopts an adjustable form (e.g., ...). Fig. 1 As shown), the specific structure includes a slide rail 11 and a lead screw 12 that are parallel to each other, and a base plate 13 installed on the slide rail and the lead screw. In use, the base plate is adjusted along the slide rail by adjusting the lead screw, thereby adjusting the distance between the cutting mechanism and the production line to ensure that the inductive components on the production line can be loaded into the cutting mechanism.

[0020] The elastic bracket is used to load inductive components and provide elastic support. Its structure includes a bracket 61, multiple sets of springs 62 on the back of the bracket, and limiting blocks 63 on both sides of the bracket. To ensure the stability of the springs during use, one end of the spring is embedded in the back of the bracket, and the other end is simultaneously embedded in the base. The springs allow the bracket to be suspended and raised. The limiting blocks are located at both ends of the bracket. The limiting blocks are L-shaped and wrap around both ends and the outer side of the bracket to limit the left and right and front and back positions when the inductive components are placed side by side, thereby ensuring that the leads of the inductive components are flush and ensuring consistency during cutting.

[0021] The lower cutter is fixed on the base with the cutter holder 10 and located on the side of the elastic bracket. The upper surface of the cutter holder is a sloping structure 101. The lower cutter is fixed at the higher end of the sloping structure, while the lower end of the sloping structure is provided with a waste port 14 on the base. The design of the sloping structure allows the cut pins to fall directly down the sloping surface to the waste port, achieving efficient collection.

[0022] The upper pressure block is fixed to the side of the column with the sliding assembly. The sliding assembly consists of a sliding groove 81 and a sliding plate 82 that cooperate with each other. The upper pressure block is fixed on the sliding plate, and the sliding groove is fixed to the side of the column. The upper pressure block slides up and down along the sliding groove under the control of a cylinder. The upper cutting blade is fixed to the lower end face of the upper pressure block. The cutting edge of the upper cutting blade is offset from the cutting edge of the lower cutting blade. When the upper cutting blade moves down, it fits against the edge of the lower cutting blade to cut the pin (similar to the principle of two blades of scissors fitting together to cut).

[0023] The upper pressure block design not only fixes the upper cutting blade, but also presses down the inductor components during cutting, preventing them from lifting or shifting during the cutting process.

[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the scope of the utility model's technical solution.
