Description

Technical Field

[0001] The invention relates to the technical field of motor production and manufacturing, and in particular to a laser paint removal system for enameled wire and a paint removal control method. Background Art

[0002] At present, the new energy vehicle industry is very active, and a large number of traditional car companies are pouring into this industry, which leads to a huge demand for drive motors for new energy electric vehicles. In the production of drive motors, there are several traditional flat copper wire winding models: X-pin, I-pin, Hair-pin, W-pin, etc. The above motors all use enameled flat copper wires, which are formed by different flat copper wire winding arrangements. Compared with traditional winding motors, due to the flat characteristics of copper wires, at the same power, the motor is smaller and has higher power, which is the development direction of the next generation of new energy drive motors. However, in the production process of this type of drive motor, the ends of the flat copper wires on the stator need to be welded, and the paint on the ends of the flat copper wires needs to be removed in advance to ensure the conduction and welding quality of the flat copper wires. The effect of removing the paint directly affects the achievement of several indicators such as welding fullness, electrical performance testing, and tensile testing. For example, Chinese patent CN115473171A discloses a laser paint stripping device, which uses laser to remove paint from flat copper wires. However, the device and the removal process have the following disadvantages: First, four sets of laser heads are required, and the positions of the four sets of laser heads relative to the flat copper wires are fixed. The laser beams received by the central area and the two side areas of the flat copper wire paint removal section have different angles with the flat copper wire surface, so that the light intensity in the central area gradually decreases from the center to the two sides, which makes the central area of ​​the flat copper wire more easily damaged, which not only affects the removal effect of the flat copper wire paint, but also increases the equipment production cost and processing cost; Second, the processing efficiency is low; due to the different performance of the motor, different types of flat copper wires are required, which makes the paint type, material and thickness of the flat copper wire surface different, and different types of paint require different wavelengths of laser, and each paint has the highest absorption rate for lasers of a specific wavelength, and has a small absorption rate or no absorption for lasers of other wavelengths. In addition, many paints are mixtures of multiple paints, including adhesives and pigments, which further increases the complexity of the paint; if an inappropriate laser wavelength is used for paint removal, the production efficiency is greatly reduced.

[0003] Therefore, there is an urgent need for a paint removal device and method that is simple to operate, has high processing efficiency, can accurately remove the paint on the surface of different types of flat copper wires at different locations without damaging the internal copper core, improves product yield, and reduces equipment cost and production cost.
