Description

Technical Field

[0001] The present invention relates to the technical field of motor processing, and more specifically, to a magnetic tile mounting mechanism and a mounting method. Background Art

[0002] In the motor assembly process, it is necessary to symmetrically mount multiple magnetic tiles on the outer circumference of the motor core. When current passes through the stator coil, the magnetic tiles will generate a magnetic field, which will interact with the magnetic field on the rotor to generate torque and drive the rotor to rotate. In the existing magnetic tile mounting process, it is necessary to apply glue on the outer circumference of the motor core, and then the operator mounts the magnetic tiles on the outer circumference of the rotating motor core coated with glue. On the one hand, manual mounting has low mounting efficiency and cannot meet the needs of large-scale magnetic tile mounting. On the other hand, different operators have different operating habits, and the consistency of the magnetic tile mounting position cannot be guaranteed, which will affect the normal use of the subsequent motor.

[0003] A Chinese patent, application number CN202323170312.0, provides a magnetic tile feeding structure for motors, which adopts a method of stacking the magnetic tiles horizontally in a transition groove and pushing them forward to mount the magnetic tiles on the surface of the core. In actual operation, since the magnetic tiles themselves have a certain height, this method of pushing and mounting the magnetic tiles will easily lead to deviations in the upper and lower positions, and it is difficult to ensure the balance of the extrusion force, which ultimately makes it difficult to ensure the mounting accuracy. It can only be used to process some motor products with low precision requirements, and is difficult to apply to some motors with relatively high precision requirements (such as motors for new energy vehicles, etc.). A magnetic tile mounting mechanism and mounting method that can ensure mounting accuracy and mounting efficiency is needed. Summary of the invention

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be described clearly and completely in combination with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are partial embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0029] The magnetic tile mounting mechanism of the preferred embodiment of the present invention is as follows: Figure 1 See also Figure 2-Figure 5, including an iron core positioning seat 1 for positioning an iron core 4 and a plurality of mounting components 2 distributed around the iron core positioning seat 1; the mounting components 2 include a first pushing unit 20 and a second pushing unit 21 which are stacked and distributed up and down; the first pushing unit 20 includes a first pushing head 200 and a first driving cylinder 201 for driving the first pushing head 200 to move laterally; the second pushing unit 21 includes a mounting base 210, on which a second pushing head 211 and a second driving cylinder 212 for driving the second pushing head to move laterally are arranged, a sliding seat 22 is arranged above the second pushing head 211, and a cylinder for the first pushing head 200 to move laterally is arranged on the upper surface of the sliding seat 22 00 sliding first slide groove 2200, the lower surface of the sliding seat 22 is provided with a second slide groove 2201 for the second pushing head 211 to slide, the sliding seat 22 is detachably connected to the mounting base 210; the front end surface of the second pushing head 211 is formed with a positioning step 2110 that matches the shape of the magnetic tile 3, the positioning step 2110 is not connected with the lower side surface, the left side surface, and the right side surface of the second pushing head 211 (that is, it is only connected with the upper side surface), and the side surface of the positioning step 2110 is an inclined surface (preferably the inclination angle range is 0-15 degrees, excluding 0 degrees), and one inclination is sufficient, and an excessively large inclination angle is not required;

[0030] During mounting, the magnetic tiles 3 are loaded onto each positioning step 2110 in batches, and the magnetic tiles 3 are leaned obliquely on the side surface of the positioning step 2110 after loading; the iron core 4 after the side surface is glued is moved to the iron core positioning seat 1 for positioning, and then the angle of the iron core 4 is adjusted so that each glue coating position 40 is directly opposite to each magnetic tile 3; the second driving cylinder 212 drives the second pushing head 211 to move horizontally, driving the lower part of the magnetic tile 3 to initially fit the lower part of the corresponding glue coating position 40 (without pressing); the first driving cylinder 201 drives the first pushing head 200 to move horizontally, so that the magnetic tile 3 turns from an oblique state to a vertical state and the middle or upper part of the magnetic tile 3 initially fits the middle or upper part of the corresponding glue coating position 40; the second driving cylinder 212 and the first driving cylinder 201 continue to operate, driving the second pushing head 211 and the first pushing head 200 to move horizontally to press the magnetic tile 3 on the corresponding glue coating position 40;

[0031] It should be noted that the second driving cylinder can adopt the segmented driving method as described above, or can control the time node of the synchronous operation of the first driving cylinder and the second driving cylinder.

[0036] By applying this batch loading structure, before loading, the magnetic tiles are pushed into the positioning groove 710 one by one under the guidance of the guide groove 712, and are positioned by magnet adsorption. Then, they are moved to the top of the iron core positioning seat 1, and the pushing head 73 is driven downward by the pushing cylinder 74.

At the same time, when mounting, the magnetic tile is innovatively straightened and mounted, and the position of the magnetic tile is positioned by the positioning step, which can well ensure the attachment accuracy. In addition, the first pushing head and the second pushing head are used to press and hold the mounting synchronously, which can also achieve the purpose of balanced control of the extrusion force of the magnetic tile mounting, thereby improving the reliability of the magnetic tile mounting and comprehensively ensuring the product quality; the overall structure is simple and the cost is low.
