Description

Technical Field

[0001] The utility model relates to the technical field of paint dripping equipment, in particular to a paint dripping device for a stator coil of a flat wire motor and a paint dripping system. Background Art

[0002] Flat wire motor is a special type of motor whose stator uses flat coils instead of traditional round coils. In order to improve the quality and performance of the motor stator and slow down the oxidation rate of the motor stator during the motor stator processing, it is necessary to apply insulating paint to the flat wire motor stator.

[0003] At present, there are two mainstream processes for the stator insulation paint coating of flat wire motors: "dip varnish" and "drip varnish". The dipping varnish equipment has a complex structure, serious waste of insulation paint and contamination, occupies a large area, has a single process flow, poor adaptability, is expensive, and has poor scalability and compatibility, and is not environmentally friendly.

[0004] The paint dripping equipment can reduce the waste of insulating paint by precisely controlling the flow rate of insulating paint. Some equipment can control the speed, and some equipment will take a certain angle of inclination to improve the dripping effect of insulating paint. However, the existing paint dripping equipment also has the following problems: the equipment function is relatively single, and heating or preheating equipment is required to assist production; the scalability is not strong; due to reasons such as available space, there are also limitations in compatibility. In addition, the mainstream paint dripping equipment cannot integrate the flow control, speed control, elevation control and temperature control of the paint dripping, resulting in space waste and unsatisfactory paint dripping effect. Even if some equipment solutions have the control of the paint dripping angle, it is not possible to coordinate the stator coil angle control with the paint dripping position, which affects the compatibility of the equipment. The existing paint dripping equipment cannot avoid the influence of poor adhesion of the insulating paint due to the total environmental changes and vibrations during the transportation and transfer process of the stator before the insulating paint is cured. The adhesion effect of the insulating paint on the coil surface is not ideal, which affects the upper limit of the development of the motor performance space such as the high-speed performance of the motor.

[0005] Therefore, in view of the problems existing in the above-mentioned paint dripping equipment, it is urgent to develop a new type of flat wire motor stator coil paint dripping equipment. Utility Model Content

[0094] (2) The gripper mechanism 1 is driven by the transfer mechanism (controlled by the PLC control system) in the mounting frame 7 to move the stator coil 6 horizontally to the set position; the set position value can be set within the range of ±10 mm; after reaching the position, the gripper module 2 opens the stator coil 6 and presses the stator coil 6 to connect it to the circuit of the gripper module 2, and the loading module 8 returns to its original position.

[0095] (3) The transfer mechanism of the mounting frame 7 returns to its original position, and the tilting module 3 tilts the stator coil 6 upward at a certain angle according to the setting. The tilting angle range is 0-45°, and the adjustment accuracy is 0.5°;

[0096] (4) The stator coil 6 is energized and heated to the set temperature, and the paint dripping module 5 is moved to the working position. The repeatability of the paint dripping module 5 is ±0.1 mm. The paint delivery position of the paint dripping module 5 can be adjusted according to the set elevation angle of the stator coil 6. The adjustment range is from 90° vertical to 20° horizontal, and can be continuously adjusted.

[0097] (5) The rotating module 4 starts to rotate at a set speed, the speed setting range is 5-30r / min, and the speed adjustment accuracy is 0.1r / min. The tilting module 3 continues to adjust the stator coil 6 to the paint dripping working position.

[0098] (6) The stator coil 6 is energized and heated to the set temperature, and the paint dripping module 5 starts dripping paint at a set flow rate. The paint dripping accuracy is M*±5% of the range and the minimum resolution is 0.1g.

[0099] (7) A larger current is passed through the stator coil 6 to heat it to the curing temperature, the rotating module 4 rotates at the set curing speed, the tilting module 3 tilts to the exit angle, and the paint dripping module 5 returns to its original position.

[0100] (8) The tilt module 3 is adjusted to a horizontal position and maintained until the set curing time. The curing time can be set to 10-60 minutes according to needs, and the adjustment unit is 1 second.

[0101] (9) The unloading module 9 moves to the docking position of the stator coil 6, and the transfer mechanism of the mounting frame 7 transports the stator coil 6 to the positioning fixture of the unloading module 9. The gripper module 2 closes and releases the stator coil 6, and returns to the original position. The unloading module 9 sends out the stator coil 6, and the loading module 8 starts loading and enters the next working cycle. The repeatability of the unloading system is ±0.05mm in the X direction (along the direction of module movement), ±1mm in the Y direction (perpendicular to the X direction in the horizontal plane), and ±0.1mm in the Z (vertical direction).
