DETAILED DESCRIPTION

[0031] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0032] Embodiment 1:

[0033] like Figure 1 As shown, an assembly device for permanent magnet sheets of a motor rotor includes a base 1, a support frame 2, a feeding mechanism 3, a press-fitting mechanism 4, a slide 5, a mounting seat 6 and a cylinder 7.

[0034] like Figure 1 As shown, the base 1 is arranged on the ground, the support frame 2 is vertically arranged on the base 1, and the feeding mechanism 3 is arranged in the middle of the support frame 2 and is used to transport the permanent magnet sheets. The pressing mechanism 4 is vertically slidably connected to the support frame 2 and is located above the feeding mechanism 3 and is used to press down the permanent magnet sheets in the feeding mechanism 3.

[0035] like Figure 1 , Figure 2 As shown, the slide 5 is horizontally slidably connected to the base 1 and is used to slide to the bottom of the feeding mechanism 3. A pair of limit plates 11 are provided on the base 1. The limit plates 11 are horizontally threadedly connected with limit rods 12 for abutting against the two ends of the slide 5, so as to realize the positioning of the sliding distance of the slide 5 and ensure high-precision assembly.

[0036] like Figure 1 , Figure 2 As shown, the mounting seat 6 is arranged on the slide 5 and is used to support the motor rotor, and the cylinder 7 is arranged below the slide 5 and is used to control the vertical sliding of the mounting seat 6. The upper end surface of the mounting seat 6 is provided with a limit column 61 embedded with the lower end of the power supply motor rotor, so as to realize the precise and rapid positioning of the motor rotor, thereby ensuring the high-precision and efficient press-fitting of the permanent magnet sheet.

[0037] When the permanent magnet sheets need to be assembled, the feeding mechanism 3 is used to transfer the permanent magnet sheets, and then the slide 5 is slid out, the motor rotor is placed on the mounting seat 6, and the limiting rod 12 is inserted into the lower end of the motor rotor to achieve the positioning installation of the motor rotor.

[0038] Then, the slide 5 is pushed back to make the slide 5 contact the limit rod 12 to realize the positioning of the slide 5, and then the cylinder 7 is used to control the mounting seat 6 to move upward to make the motor rotor contact the feeding mechanism 3. Then, the pressing mechanism 4 is controlled to work to press the permanent magnet sheet on the feeding mechanism 3 into the motor rotor to realize the pressing of the permanent magnet sheet.

[0039] By setting up highly automated assembly equipment, the automatic pressing of permanent magnet sheets can be achieved, which greatly improves the installation efficiency, while also improving the installation accuracy and yield rate, saving manpower and material resources, and meeting the needs of modern production.

[0040] like Figure 1 , Figure 3 , Figure 4 As shown, the feeding mechanism 3 includes a feeding plate 31, a feeding seat 32, a slide rail 33 and a pusher 34. The feeding plate 31 is horizontally arranged on the support frame 2, the feeding seat 32 is arranged at the center of the feeding plate 31, and the side walls of the feeding seat 32 are all provided with grooves 35 for permanent magnets to be embedded.

[0041] like Figure 1 , Figure 3 , Figure 4 As shown, a feeding hole 36 connected to the lower end of the groove 35 is provided on the feeding plate 31, and the slide rail 33 is arranged around the feeding seat 32 and connected to the groove 35. A guide plate 37 located above the slide rail 33 is horizontally arranged around the feeding seat 32, and the guide plate 37 abuts against the upper end of the permanent magnet sheet, and the front end of the guide plate 37 is arranged to be tilted upward.

[0042] like Figure 1 , Figure 3 , Figure 4 As shown, a baffle 38 supporting the permanent magnet sheet is horizontally slidably connected to the inner wall of the feeding hole 36 , and the upper end of the baffle 38 is arranged in an inclined surface. An elastic member 39 is arranged in the feeding hole 36 to push the baffle 38 to slide outward.

[0043] like Figure 1 , Figure 3, Figure 4 As shown, the pusher 34 is disposed on the slide rail 33 , and includes a pusher plate 341 and a spring 342 . The pusher plate 341 is slidably connected to the slide rail 33 , and the spring 342 is disposed between the pusher plate 341 and the rear end of the slide rail 33 .

[0044] like Figure 1 , Figure 3 , Figure 4 As shown, the pressing mechanism 4 includes a pressing head 41 and a pressing plate 42. The pressing head 41 is vertically slidably connected to the support frame 2, and the pressing plate 42 is vertically arranged on the pressing head 41. The loading seat 32 is vertically provided with a sliding hole 43 that connects the groove 35 and allows the pressing plate 42 to slide vertically.

[0045] When loading the permanent magnet sheet, pull the push plate 341 backward, then place the permanent magnet sheet on the slide rail 33, and use the spring 342 to push the push plate 341 to automatically press the permanent magnet sheet, so that the permanent magnet sheet moves toward the groove 35 and the discharge hole, and the permanent magnet sheet at the final end is embedded in the groove 35.

[0046] When the permanent magnet sheet is press-fitted, the pressure head 41 and the pressure plate 42 are controlled to move downward, so that the pressure plate 42 slides in the sliding hole 43 and presses the permanent magnet sheet to slide downward. During the sliding process of the permanent magnet sheet, the baffle 38 will be automatically pressed inward to slide, so that the permanent magnet sheet slides into the motor rotor, completing the press-fitting operation.

[0047] When the press-fitting is completed, the press plate 42 retreats, and the baffle 38 slides outwards and supports the permanent magnet sheet to prevent the permanent magnet sheet from falling, thereby ensuring the stable transmission and press-fitting of the permanent magnet sheet.

[0048] Embodiment 2:

[0049] like Figure 5 As shown, an assembly device for permanent magnet sheets of a motor rotor is different from Example 1 in that: a pusher 34 includes an iron core 343, which is embedded in a groove 35 and is used for adsorbing the permanent magnet sheets, and under the magnetic force of the permanent magnet sheets, the permanent magnet sheets are automatically transmitted one after another.

[0050] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
