Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic wire coating equipment, and in particular to a coating device for producing rectangular electromagnetic wires. Background Art

[0002] Electromagnetic wire is a conductive metal wire with an insulating layer, which is mainly used to manufacture coils or windings in electrical products. In the actual manufacturing of electromagnetic wire, it is necessary to coat the surface with an insulating layer multiple times to ensure the insulation breakdown resistance quality. Rectangular wire can better adapt to the shape of the motor slot, which increases the slot fill rate. The current coating device for rectangular electromagnetic wire production is not convenient for continuous negative pressure coating. The electromagnetic wire needs to be coiled as a whole and then dipped in negative pressure paint. In addition, the traditional normal pressure coating method is prone to bubbles in the paint during the subsequent drying process. The bubbles between the electromagnetic wires affect the insulation quality. At the same time, it is not convenient to automatically perform comprehensive insulation quality testing. It is not convenient to re-apply paint in time when leakage defects occur in the electromagnetic wire, which further affects the insulation quality of the structure. At the same time, the electromagnetic wire is prone to relaxation during the transportation process, which affects the uniformity of the electromagnetic wire coating. Summary of the invention

[0044] Working principle of this embodiment: First, the coating mounting frame 101 is installed on the electromagnetic wire production line by passing the bolts through the through holes on the coating mounting frame 101; the electromagnetic wire passes through the sliding insertion sleeve 104 and the upper rubber sleeve 206 and then passes through the guide rubber tube 502 and the discharge rubber tube 503. During the process, the vacuum pump connected to the suction tube 204 can be used to draw vacuum. As the electromagnetic wire is transported, the solenoid valve of the paint inlet pipe 303 is timed to switch, and paint is injected into the coating sponge tube 302, and the paint is coated on the electromagnetic wire through the coating sponge tube 302; when the electromagnetic wire is transported by the production line, the electric heating plate 4011 is energized to dry the paint. As the electromagnetic wire is transported, when it passes through the conductive storage tank 5011, the conductive storage tank 5011 is filled with a low-concentration sodium chloride solution, which can achieve conductivity. At this time, once there is a vacancy on the surface of the paint, the power supply shaft 202 is pressed by the spring to drive the anti-wear ball 203 to roll and fit on the surface of the electromagnetic wire to achieve power supply. At this time, the position of the coating defect will be connected to the power terminal 5 through the sodium chloride solution. 04, at this time, the leakage indicator light 205 can realize the lighting of the passage; after the power terminal 504 is connected to the electromagnetic wire, the electromagnet 606 is also connected to the electromagnetic wire, and the piston 605 is magnetically attracted. At this time, the piston 605 moves inside the pressure supply cylinder 604, generating air pressure, controlling the expansion of the airbag 602, so that the re-coating sponge pad 603 is attached to the outside of the electromagnetic wire, and the outside of the electromagnetic wire is re-coated with paint; when the electromagnetic wire moves in the drying and curing part 4, the elastic paddle 702 drives the roller 703 to roll and fit the electromagnetic wire, Once the electromagnetic wire becomes loose, the roller 703 will squeeze the electromagnetic wire to the left under the pressure of the elastic pick 702, and the elastic power connecting piece 704 will be separated from the power contact 7011. At this time, the relaxation indicator light 103 will go out to prompt. Correspondingly, when the electromagnetic wire is tightened, the electromagnetic wire will squeeze the roller 703 to make the elastic power connecting piece 704 fit with the power contact 7011, and the relaxation indicator light 103 will light up normally; open the sealing plug on the top of the conductive delivery tube 506 to put in a low-concentration sodium chloride solution.
