Description

Technical Field

[0001] The utility model relates to the technical field of enameled wire pre-cutting, in particular to a laser cutting pre-wire cutting mechanism. Background Art

[0002] Before traditional enameled wire winding operations involving magnetic rings, multiple pre-cutting devices are typically used to pre-cut a portion of the enameled wire, allowing it to be easily torn off during subsequent operations. These pre-cutting devices primarily consist of a cutter transmission mechanism connected to a pneumatic cylinder, a cutter connected to the cutter transmission mechanism, and a cutter fixing block with a through-hole for accommodating the cutter. The cutter fixing block has a U-shaped upper end, with ceramic wire eyelets on either side extending through the U-shaped wall. A limit block is installed above the cutter fixing block. During operation, the enameled wire passes through two opposing ceramic wire eyelets, and the cylinder drives the cutter transmission mechanism upward, thereby driving the cutter upward. The limit block limits the depth of the cutter's penetration, ensuring that only a portion of the enameled wire is cut.

[0003] However, in practice, this pre-cutting device has some shortcomings. First, because different product models require different lengths of enameled wire head and tail when winding the magnetic ring, the position of the pre-cutting device must be frequently adjusted to determine the required pre-cut positions, which is very inconvenient for installation. Second, after long-term use, the cutter tends to wear and become blunt, making it impossible to accurately reach the preset cutting depth, resulting in substandard products.

[0004] Therefore, it is necessary to design a laser cutting pre-breaking mechanism to solve the above problems. Utility Model Content

[0005] In response to the above-mentioned defects of the prior art, the utility model provides a laser cutting pre-cutting mechanism, which aims to solve the problems of difficulty in adjusting the length between the end and end of the enameled wire caused by the inconvenience of installation of traditional pre-cutting devices and inaccurate cutting depth caused by easy wear of the cutter.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a laser cutting pre-breaking mechanism, including a laser component and a routing component, the routing component is arranged on one side of the laser component, the routing component includes a wire length control winding component, the wire length control winding component includes a pre-breaking wire length control guide rail, several first positioning wheels for horizontal displacement adjustment along the pre-breaking wire length control guide rail, a welding table and a rewinding transmission shaft, and several enameled wires output by the external winder correspond to each first positioning wheel respectively, the enameled wire passes through the first positioning wheel and the welding table in turn, reaches the rewinding transmission shaft, and winds back to the lower end of the first positioning wheel, bypasses the first positioning wheel again and enters the welding table again, the position where the same enameled wire enters the welding table for the first time is defined as the wire head pre-breaking point, and the position where it enters the welding table for the second time is defined as the wire tail pre-breaking point, and the laser head of the laser component simultaneously performs pre-breaking operations on the wire head pre-breaking point and the wire tail pre-breaking point.

[0007] Based on the above, the beneficial effect of a laser cutting pre-cutting mechanism is to solve the problems of difficulty in adjusting the length between the end and end of the enameled wire caused by the inconvenience of installation of the traditional pre-cutting device and the inaccurate cutting depth caused by easy wear of the cutter; it is mainly reflected in:

[0008] 1.

[0009] 2. Using laser components instead of traditional mechanical cutters avoids the accuracy of cutting depth affected by cutter wear. Laser cutting has high precision and stability, which can ensure that each cut reaches the predetermined depth and improve product quality.

[0010] Furthermore, the routing assembly also includes an interval adjustment winding component, which includes an interval adjustment sliding guide rail, several second positioning wheels for vertical displacement adjustment along the interval adjustment sliding guide rail, and an outer winding transmission shaft. After the enameled wire comes out of the welding table, it goes up along the lower end of the outer winding transmission shaft to bypass the second positioning wheel, and then goes down from the second positioning wheel and through the outer winding transmission shaft to the next processing device.

[0011] Based on the above, the beneficial effect of the interval adjustment winding component is that by adjusting the second positioning wheel in the vertical direction, the spacing between one group of wire head pre-break points and wire tail pre-break points to the next group of wire head pre-break points and wire tail pre-break points on the same enameled wire is adjusted, ensuring that the distance between adjacent wire head and wire tail pre-break points on the enameled wire is precisely controlled; the beneficial effect of the interval adjustment sliding guide rail is to allow the second positioning wheel to move and position smoothly in the vertical direction; the beneficial effect of the outer winding drive shaft is to support and guide the enameled wire from the welding table to the next processing step, ensuring a smooth transition of the enameled wire.

The plurality of horizontal guide rods are evenly arranged on the horizontal guide rail frame, and each of the horizontal guide rods is slidably fitted with a first guide wheel seat, and each of the first guide wheel seats is provided with a first positioning wheel.

[0013] Based on the above, the beneficial effect of the horizontal guide rail frame is to install the horizontal guide rod; the beneficial effect of the horizontal guide rod is to install the first guide wheel seat in a sliding fit; the beneficial effect of the first guide wheel seat is to install the first positioning wheel.

[0014] Furthermore, a crossbeam is provided at the input end of the horizontal guide rail frame, and a plurality of enameled wire positioning rod groups are provided on the crossbeam. Each of the enameled wire positioning rod groups corresponds to one of the first positioning wheels, and is used for positioning the input enameled wire.

[0015] Based on the above, the beneficial effect of the crossbeam is to fix the enameled wire positioning rod group, ensuring that the enameled wire can accurately enter the first positioning wheel when it is output from the external reel; the beneficial effect of the enameled wire positioning rod group is to accurately guide the input enameled wire, ensuring that it is smoothly connected to the first positioning wheel.

[0016] Furthermore, the interval adjustment sliding guide rail is composed of a vertical guide rail frame, a plurality of vertical guide rods and a plurality of second guide wheel seats. The plurality of vertical guide rods are evenly arranged on the vertical guide rail frame, and each of the vertical guide rods is slidably fitted with a second guide wheel seat, and each of the second guide wheel seats is provided with a second positioning wheel.
