Description

Technical Field

[0001] The invention relates to the technical field of automotive micro-motor tooling equipment, and in particular to an automatic assembly device for automotive micro-motor magnetic tiles and magnetic tile clips. Background Art

[0002] See also Figure 1 and Figure 2 The figure shows a schematic diagram of the structure of the casing of a micromotor for automobiles. Two magnetic tiles 20 are arranged in the casing 10 of the micromotor for automobiles. A magnetic tile clip 30 (U-shaped spring) is arranged between the two magnetic tiles 20 to pressurize one side of the magnetic tile 20, so as to achieve circumferential limitation of the two magnetic tiles 20. In order to prevent the wrong installation of magnetic tiles, most of the magnetic tiles are installed in place before magnetization. In order to achieve a good magnetization effect, not only must the magnetic tiles be accurately installed in the designed position, but also the magnetic tiles and the casing are not allowed to be fixed with glue. Generally, the deformation elastic force of the magnetic tile clip (U-shaped spring) is directly used to fix the magnetic tiles. Therefore, on the one hand, the magnetic tile clip must be accurately installed in the designed position to apply an accurate force to the magnetic tile, and on the other hand, a steel wire with appropriate stiffness must be selected to achieve a larger elastic force to fix the magnetic tile under the same deformation amount. However, the existing automotive micromotor magnetic tiles and magnetic tile clips are usually assembled manually or semi-automatically, which easily leads to improper assembly of the magnetic tiles and / or magnetic tile clips, poor assembly effect, low assembly pass rate, and low assembly efficiency. To this end, the applicant has conducted useful explorations and attempts and found a solution to the above problems. The technical solution to be introduced below was produced under this background.
