Description

Technical Field

[0001] This utility model relates to the field of coil production equipment technology, and in particular to a lead-cutting unit for precise coil positioning. Background Technology

[0002] During the production of existing inductors, the pins at the bottom need to be cut to make their length suitable for production requirements. The most common method for cutting coil pins is to manually shorten multiple pins using wire cutters. Since the pins are metal, the operator needs to expend considerable force to cut them, making manual cutting inefficient. Furthermore, manual cutting inevitably introduces errors, resulting in pins that are not perfectly level after cutting, compromising quality. Utility Model Content

[0003] The purpose of this invention is to provide a cutting unit for precise coil positioning, which addresses the shortcomings of existing technologies. This invention can accurately position, straighten, and cut the coil pins, ensuring that the four pins are level after cutting, thus guaranteeing product quality.

[0007] Preferably, the pressure plate includes a connecting part and a clamping part, the connecting part and the clamping part are arranged in an L-shape, and the connecting part is fixedly connected to the piston rod of the second drive cylinder.

[0008] Preferably, the fixed horizontal plate is provided with a slide rail, and the connecting part of the pressure plate is provided with a slide groove that is slidably connected to the slide rail.

[0009] The beneficial effects of this utility model are as follows: When the coil is pressed to the front end of the fixed plate, the four pins of the coil are separated by the first partition plate. The two pins on the left side of the coil are located in the first pin slot, and the two pins on the right side of the coil are located in the second pin slot.

The first clamping mechanism 54 includes a pressing plate 541 and a second driving cylinder 542 for driving the pressing plate 541 to move laterally along the X-axis.

[0016] In this embodiment, the coil is pressed to the front end of the fixing plate 2. The four pins of the coil are separated by the first partition plate 33. The two pins on the left side of the coil are located in the first pin slot 31, and the two pins on the right side of the coil are located in the second pin slot 32. Then, the piston rod of the first driving cylinder 52 extends, the fixing horizontal plate 53 moves linearly along the Y-axis and approaches the pins of the coil, the piston rod of the second driving cylinder 542 extends, the pressing plate 541 moves laterally along the X-axis, and the two pins on the left side are clamped together with the second partition plate 56 (the second clamping mechanism 55 works simultaneously to clamp the two pins on the right side). Then, the piston rod of the first driving cylinder 52 retracts, the fixing horizontal plate 53 returns to its original position, and the pins are straightened. After the pins are straightened, the first cutting mechanism 41 and the second cutting mechanism 42 at both ends of the fixing plate 2 work to cut the four pins of the coil. This utility model can accurately position the coil pins and straighten and cut them. The four pins can be made horizontal after cutting, ensuring product quality.
