[0021] The rotor gold powder coating device 9 includes a frame 26, a frame panel 27 on the frame 26, a gold powder pool 28 on the frame panel 27, gold powder inlets 29 on both sides of the gold powder pool 28, a first coating roller 30 and a second coating roller 31 arranged in parallel inside the gold powder pool 28, the first coating roller 30 and the second coating roller 31 are mounted on a coating roller bracket 33 through a bearing seat 32, the first coating roller 30 is connected to a gear on a reduction motor 35 located at the lower part of the frame panel 27 through a first chain 34, and the second coating roller 31 is connected to a gear on a reduction motor 35 located at the lower part of the frame panel 27 through a second chain 36, and a rotor 5 to be coated with gold solution is arranged between the first coating roller 30 and the second coating roller 31.

[0022] Furthermore, the bottom of the frame 26 is provided with feet 37 to increase the stability of the frame 26.

[0023] Furthermore, the first coating roller 30 and the second coating roller 31 move in the same direction, uniformly brushing the gold powder in the gold powder pool 28 onto the surface of the rotor 5.

[0024] Furthermore, a reinforcing rib 38 is provided between the fixing plate 14 and the support plate 16.

[0025] Furthermore, the bottom of the transfer bracket 13 is provided with a foot flange 39; this facilitates fixing it to the ground and increases stability.

[0027] Furthermore, the lower part of the ejector dual-shaft cylinder 20 is provided with a cylinder bracket 41 connected to the bottom of the fixing plate 14.

[0028] This invention provides a motor rotor machining and assembly unit. The specific working principle is as follows: CNC precision lathe 2 and CNC lathe 3 first machine the rotor 5 and the rotor shaft respectively. After machining, they are press-fitted on the CNC press 7. The press-fitted workpiece enters the working area of ​​the three-axis gantry robot 12 through the rotor transfer device 8. The three-axis gantry robot 12 grabs the workpiece and places it on the turning and grinding integrated machine 42 for the rotor outer circle turning and grinding integrated operation. After completion, the rotor 5 is automatically dimensionally inspected on the rotor finished product automatic inspection platform 10 to determine whether it is qualified. The qualified workpiece is transferred to the rotor gold powder coating device 9 for outer circle coating. After the coating is completed, the rotor is placed on the finished product placement trolley 11.

[0029] When the rotor transfer device 8 of the present invention needs to transfer the rotor, the movable end of the push-out dual-axis cylinder 20 extends and pushes out the rotor 5 located in the first groove 19. The rotor slides down from high to low along the linear motion unit support 18 and slides into the second groove 21. The positioning dual-axis cylinder 23 is activated to correct the position of the rotor 5, which facilitates the subsequent transfer of the rotor by the three-axis gantry robot 12. The second groove 21 is provided with a polyurethane edge strip 22, which serves to buffer and protect the rotor 5.

[0030] The outer surface of the rotor 5 of this invention is coated with gold powder to prevent the rotor 5 from rusting. When working, the geared motor 35 is started, and the geared motor 35 drives the first coating roller 30 and the second coating roller 31 to move in the same direction, so as to evenly coat the gold powder in the gold powder pool 28 onto the outer surface of the rotor 5, which saves time and effort.

[0031] This invention employs a modular operation method, centralizing equipment, increasing production efficiency by 5 times, reducing the number of transfers by 10, and freeing up 10 workers. It saves the company approximately 800,000 yuan annually and generates approximately 1.5 million yuan in additional economic benefits annually, enhancing its market competitiveness.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
