Description

Technical Field

[0001] The utility model relates to the technical field of motor coil processing equipment, in particular to a paint dipping device for producing permanent magnet direct-drive hub motor coils. Background Art

[0002] A permanent magnet direct drive motor is a motor that uses permanent magnets to generate a magnetic field and controls the force of the magnetic field through current to achieve rotation. Its working principle is based on Faraday's law. Faraday's law states that when the current passing through one coil changes, an electromotive force will be generated in another coil. This electromotive force is caused by the change of the magnetic field. In a permanent magnet direct drive motor, a constant magnetic field is generated due to the presence of permanent magnets. When current is passed through the coil, a changing magnetic field is generated. This changing magnetic field will generate an electromotive force in the permanent magnet, thereby generating a force. This force can drive the motor to rotate. Therefore, the working principle of a permanent magnet direct drive motor is to use the magnetic field generated by the permanent magnet and the change of the current passed through the coil to achieve rotation. In the prior art, in order to improve the moisture resistance and corrosion resistance and insulation strength of the motor coil, and to improve the mechanical strength, thermal conductivity and heat dissipation effect and delay aging, the motor coil needs to be dipped in paint.

[0003] The existing permanent magnet direct drive hub motor coil production varnishing device generally needs to varnish the motor coils one by one, which is inconvenient to load and unload and has low work efficiency. Summary of the invention

[0006] Furthermore, bending portions are vertically bent on both sides of the top of the placement basket, a support plate is horizontally arranged at the top of the outer wall of the paint storage cavity, and the linear drive mechanism includes a first linear drive component that pushes the bending portion to move vertically up and down and a plurality of guide components vertically arranged at the bottom end of the bending portion, and the guide components are slidably connected to the support plate.

[0008] Furthermore, the axes of the first guide rod and the second guide rod coincide with each other, and a sliding groove matching with the second guide rod is arranged inside the first guide rod.

[0009] Furthermore, fixing plates for support are arranged on both sides of the paint storage chamber outside close to the first material storage tank and the second material storage tank, and fixing members for fixing the first guide rod and the second guide rod are arranged on the fixing plates.

[0010] Furthermore, the pushing mechanism includes a pushing plate and a second linear driving member that pushes the pushing plate to slide horizontally inside the first material storage tank.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The permanent magnet direct drive hub motor coil production varnishing device can varnish multiple motor coils at the same time by providing a placement basket, and by providing a linear drive mechanism, a first material storage tank, a pushing mechanism, and a second material storage tank. After a batch of products is varnished, the placement basket is driven to rise by the linear drive mechanism, and the next batch of coils to be varnished is pre-placed on the first material storage tank, and then the coils are pushed horizontally by the pushing mechanism, so that automatic loading and unloading is realized, thereby improving work efficiency.
