Anti-rust treatment device for plastic-encapsulated stator and its application method

Abstract

The invention relates to the technical field of intelligent processing equipment, in particular to a plastic-sealed stator anti-rust treatment device and a method for using the same, comprising a casing, a conveying mechanism, a tray, a dust blowing and anti-seepage mechanism and a coating mechanism, and is characterized in that the casing is a rectangular hollow The box body; the transmission mechanism is arranged in the lower area of ​​the shell, and is composed of a synchronous belt mechanism driven by a servo motor. The synchronous belt mechanism is provided with a tray; The plastic-encapsulated stator is placed in the slot; the dust-blowing and anti-seepage mechanism is arranged below the transmission mechanism; the coating mechanism is located above the transmission mechanism, facing the dust-blowing and anti-seepage mechanism. The beneficial effects of the invention are as follows: the device for anti-rust treatment in a clean state of the inner cavity of the plastic-encapsulated stator can be maintained all the time, and the anti-rust liquid can also be prevented from penetrating into the bearing chamber of the end cover.

Description

technical field [0001] The invention relates to the technical field of intelligent processing equipment, in particular to a plastic-sealed stator anti-rust treatment device and a use method thereof. Background technique [0002] The plastic-encapsulated motor uses plastic packaging technology to package the stator core and winding of the motor with engineering plastics, which can cancel the traditional motor stator insulation treatment process and the metal casing of ordinary motors. This kind of micro motor is used in household appliances such as vacuum cleaners, range hoods, air conditioners, washing machines and instrument fans. [0003] The stator core of the plastic-encapsulated motor is made of two semicircular iron cores combined into a full circle. The stator with winding windings is put into the injection molding machine for injection molding through thermosetting plastics. After the injection molding is completed, the plastic-sealed stator goes to the next step of...

Problems solved by technology

[0004] For the antirust treatment of plastic-sealed stators, the current method is that workers manually use a brush to apply light gold water to the surface of the stator core in the inner cavity of the plastic-sealed stator. However, due to the large uncontrollable variables of manual operation, light gold water is easy to apply Evenly, and it is easy to apply the fresh gold water to the bearing chamber in the plastic-sealed stator end cover. Due to the high precision requirements of the bearing chamber, the dimensional accuracy of the bearing chamber will be affected by the drying of the fresh gold water after entering the bearing chamber. After the motor assembly is put into the rotor, the rotor The bearing and the bearing chamber cannot fit tightly, which will cause abnormal noise of the bearing

Moreover, although the inner cavity of the plastic-sealed stator has been cleaned before applying fresh gold water, there is still a chance that the plastic-sealed compound residue will remain in the stator, and the plastic-sealed stator will also fall into dust during the process of stacking and waiting for anti-rust treatment. If you apply light gold water, the dust particles will be glued to the surface of the plastic-sealed stator core by the quick-drying light gold water, and will be rubbed by the rotor after assembly, causing abnormal noise.
