Description

Technical Field

[0001] The utility model relates to the technical field of motor manufacturing and automated coating, in particular to an iron core coating tool. Background Art

[0002] In motor manufacturing, the iron core coating process is a key step in improving motor performance and ensuring product quality. As the core component for converting electromagnetic energy, the glue coating on the iron core not only provides insulation and protection but also directly affects the motor's magnetic flux path and energy conversion efficiency. Therefore, the uniformity and quality of the iron core coating are crucial to the overall performance of the motor.

[0003] However, traditional core coating methods are struggling to meet the high-precision and high-efficiency requirements of modern motor manufacturing. First, while the manual immersion method is simple and easy to use, it has significant limitations. Due to the uncontrollable nature of manual operation, it is difficult to ensure that every core receives a uniform coating during the immersion process. Furthermore, the glue can easily form bubbles or sag on the core surface during the immersion process, further affecting the coating's uniformity and aesthetics. More importantly, the manual immersion method is inefficient and cannot meet the demands of large-scale production. In contrast, simple mechanical spraying methods have improved coating efficiency to a certain extent, but they still have many shortcomings. While mechanical spraying can be automated, the uniformity and precision of the nozzle are often limited by the mechanical design and manufacturing process. During the spraying process, parameters such as the distance between the nozzle and the core, the angle, and the spraying speed are difficult to precisely control, which can easily lead to uneven coating thickness, missed coating, or re-coating. Mechanical spraying is particularly challenging for cores with complex shapes and compact structures, as it cannot ensure that the glue fully penetrates every nook and cranny.

[0004] In addition to the two methods mentioned above, some manufacturers have tried other coating techniques, such as roller coating and brush coating. However, these methods also have problems such as uneven coating and low efficiency, and cannot meet the motor manufacturing industry's demand for high-quality and high-efficiency coating.
