Problems solved by technology
[0004] There are following deficiencies in the prior art: 1. The iron core assembly machine of general DC motor directly adopts the vibrating plate feed when the square magnetic steel is fed laterally, and the feeding chute width of the vibrating plate is not the same as the transverse width of the square magnetic steel. Correspondingly, the width of the feeding chute is wider than the longitudinal width of the square magnet, and the square magnet is prone to skew during the feeding process, thus affecting the direction of magnet conveying
2. When the steel sheet is transported, the round head suction cup is used to directly absorb and transport the square steel sheet, and the steel cannot be limited. The steel sheet is easy to move during the handling process, which affects the adhesion accuracy of the steel sheet
3. When adjusting the direction of the steel sheet, it is necessary to manually place the steel sheet in a certain direction in advance, and the mounting direction of the steel sheet cannot be automatically adjusted, which affects the efficiency of the steel sheet mounting

The invention relates to the field of direct current motors and discloses an iron core assembling machine of a direct-current motor. The machine comprises a workbench and also comprises a magnetic steel conveying device, a gluing device, a steel sheet pasting device and a jig assembly line which are arranged in the magnetic steel conveying device. A magnetic steel straightening mechanism is arranged in the magnetic steel conveying device to prevent a magnetic steel from being conveyed obliquely. A steel sheet moving mechanism is arranged in the steel sheet pasting device to limit a steel sheetwhen the steel sheet is moved, so that the pasting precision is guaranteed. A steel sheet detection mechanism and a steel sheet rotary positioning mechanism are arranged in the steel sheet pasting device to adjust the pasting direction of the steel sheet, and the low efficiency of manual adjustment is avoided.
Description
technical field [0001] The invention relates to the field of DC motors, in particular to an iron core assembly machine and method for DC motors. Background technique [0002] The iron core in the DC motor mainly includes magnetic steel and steel sheets, wherein the steel sheets are fixed on the surface of the magnetic steel in a certain direction. During the assembly process of magnets and steel sheets, first glue the surface of the magnets, then place the steel sheets in a certain direction and move the steel sheets to the glued surface of the magnets for pasting and fixing to complete the magnet and steel sheets. assembly. DC motors are widely used in mechanical equipment such as automobiles, household appliances, and lifting machinery, and have an increasingly important position. [0003] The State Intellectual Property Office of China has published the publication number CN207184279U, and the patent name is a motor rotor magnetic steel pasting device, which includes a ...
