[0002] The stator coil in the motor is used to generate a magnetic field. Generally, the motor casing has a permanent magnet. When a magnetic field is generated in the coil, the permanent magnet exerts a magnetic force on the coil, causing rotation. After searching, the prior art (application number: CN202123155814.7) records "an automatic coating device for insulating powder of motor coils, including a box body, two screw rods are symmetrically arranged at the left and right ends of the inner wall of the box body, a connecting plate is threadedly connected to the screw rod, and a hydraulic push rod is arranged at one end of the connecting plate. Two powder storage boxes are symmetrically arranged at the lower end of the screw rod, a powder spraying head is arranged on one side of the powder storage box, a collecting box is arranged at the lower end of the powder storage box, and a box door is arranged on the outer side of the collecting box. In the utility model, a screw rod structure is arranged inside the device, and the motor coil is driven in and out of the feed port through the screw rod structure, which is more convenient for the coating process inside the device. A hydraulic push rod structure is arranged inside the screw rod structure inside the device, and a turntable structure is arranged on the hydraulic push rod structure, so that the motor coil can be rotated and fixed inside. A collecting box is arranged at the lower end of the device, and the insulating powder scattered during the coating process is collected by the collecting box, so that the device does not waste insulating powder. "

[0003] However, the clamping pads involved in the automatic coating equipment for motor coils in the prior art will cause part of the coil to be blocked when clamping the stator coil, resulting in incomplete spraying. Secondly, the insulating coating of the electronic coil usually requires comprehensive spraying, while the above-mentioned equipment can only spray the outside. The stator coil is generally a cylindrical structure, which makes it impossible to achieve uniform spraying on its inner wall. Manually adjusting the fixed angle of the stator coil and adjusting the spraying area will reduce the processing efficiency. Utility Model Content

[0004] In order to overcome the defects of the prior art, a stator insulation layer coating machine is provided to solve the problems of incomplete insulation spraying of the stator coil and low processing efficiency in the existing motor coil automatic coating equipment.

[0005] To achieve the above-mentioned purpose, a stator insulation layer coating machine is provided, including: a chassis, a first cylinder and a bracket assembly, a chassis door is provided on the outside of the chassis, and a powder storage box and a powder extractor are provided on the outer wall of the chassis, and a collecting box is provided on the front side of the chassis, the first cylinder is installed on the top of the chassis, and the bracket assembly is connected to the lower end of the first cylinder, and vertical electric push rods are provided on both sides of the bracket assembly, the inner side of the powder extractor is connected to a side nozzle, and the inner side of the side nozzle is connected to a center nozzle.

[0008] Furthermore, the lower end of the vertical electric push rod is connected to the horizontal electric push rod, and the inner end of the horizontal electric push rod is connected to the clamping block.

[0009] Furthermore, the bottoms of the side nozzles and the central nozzle are connected via a horizontal connecting pipe, and the inner tube wall of the side nozzles and the tube walls on both sides of the central nozzle are provided with powder spraying heads.

[0010] Furthermore, the hanger assembly includes a positioning column connected to the lower end of the rotating shaft, and the outer end of the positioning column is hinged with four second cylinders, and the lower piston rod end of the second cylinder is hinged with a hanging rod.

[0011] Furthermore, the upper end of the hanging rod is hinged to the lower end of the positioning column, and the lower end of the hanging rod is provided with an inclined hook.

[0012] The beneficial effects of the utility model are:

[0013] 1. When in use, first open the box door and insert the stator coil upward in the vertical direction to the outside of the hanging rod, then start the second cylinder to drive the bottom of the hanging rod to rotate outward until the hook is supported on the bottom of the stator coil to form a stable support for the stator coil, then start the first cylinder, and move the hanger assembly and the electronic coil downward at the same time through the first cylinder, so that the central nozzle is inserted into the inside of the stator coil, and then start the motor and the powder pump, so that the motor drives the stator coil to rotate, and at the same time, the stator coil is sprayed through the central nozzle and the side nozzle, so as to achieve comprehensive and uniform spraying of the inside and outside of the stator coil at the same time;

[0014] 2. After spraying for a period of time, stop spraying and move the bracket assembly upward. At this time, start the vertical electric push rod and the horizontal electric push rod to drive the clamp to clamp the outside of the stator coil. Then start the motor to drive the bracket assembly to rotate a certain angle, so that the clamped position is different from the original position. Then, when spraying again, the part originally blocked by the bracket assembly can be fully sprayed. Therefore, you only need to operate inside the chassis to complete the angle adjustment of the stator coil, thereby improving the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] As a preferred embodiment, when insulating paint is used to spray the stator coil, an electric hot air blower 15 and an air diffuser hood 151 are provided so that after spraying, the insulating paint on the outside of the stator coil can be blown dry to facilitate rapid curing.
