Description

Technical Field

[0001] This utility model relates to the field of paint dripping equipment, and in particular to a dual-coil switching heating device for paint dripping equipment and the paint dripping equipment itself. Background Technology

[0002] The stator consists of silicon steel sheets and stator windings. The stator windings are bonded into an insulating whole by dripping insulating varnish, which prevents the stator winding wires from loosening. To improve the effect of varnish dripping or coating, the stator needs to be preheated using a stator preheating device or a heating device needs to be installed at the varnish dripping station so that heating can be carried out simultaneously with varnish dripping.

[0003] In existing technologies, the heating devices configured on the same stator preheating equipment or paint spraying equipment typically have a fixed heating capacity / efficiency. For example, CN218678780U discloses a stator preheating device, including a worktable with two positioning components. A heating coil is positioned above the positioning components and connected to a coil inductor located on the worktable. The positioning components include a positioning seat on the worktable, which is adjustable in height. Multiple support blocks are arranged circumferentially on the upper side of the positioning seat. The positioning seat and the support blocks are integral parts. The positioning seat is barrel-shaped, and the support blocks are arc-shaped plates with their centers concentric with the positioning seat. Gaps are left between the support blocks, and the outer surfaces of the support blocks are flush with the outer surfaces of the positioning seat. The thickness of the support blocks is less than the thickness of the positioning seat. In use, the positioning seat moves upward, causing the stator to move into the heating coil. The heating coil heats up, thereby achieving stator preheating. Since heating capacity / efficiency is usually fixed and single, different products require different heating times. This is especially true for the heating devices configured on the coating equipment, which heat the stator products to be coated during coating. Different stator products have different heating capacity requirements. If a dedicated coating equipment is used for each stator product, it will inevitably lead to a series of problems such as more equipment, higher purchase costs, and troublesome equipment storage and management. Therefore, the industry generally uses the same coating equipment to accommodate coating operations for different stator products. However, it is difficult to meet the ideal heating capacity requirements of different stator products, which limits the further improvement of coating quality.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0030] A dual-coil switching heating device for a paint dripping equipment includes an X-axis moving mechanism 10, a translation seat 11, a first Y-axis moving mechanism 21, a second Y-axis moving mechanism 22, a first heating coil unit 201, and a second heating coil unit 202. Both the first heating coil unit 201 and the second heating coil unit 202 include an IH induction heating coil, which extends into the stator product for heating. The X-axis moving mechanism 10 drives the translation seat 11 to move along the X-axis.
