Micro motor fully automatic packaging machine

Abstract

The invention relates to a micro motor fully automatic packaging machine. The micro motor fully automatic packaging machine includes a rack, a shell guide rail, a turntable, a steeping driving device and a rotor pushing and pressing mechanism; a plurality of magnetic attraction grooves of which the section is half round are distributed on the turntable along the circumferential direction of the turntable at equal intervals; and the rotor pushing and pressing mechanism includes a push-in lifting mechanism, a rotor pushing rod, an adapting lifting mechanism, an adapting lifting seat, an adapting bottom plate, an adapting fixed clamping sheet, an adapting movable clamping sheet and an adapting air cylinder. Since the adapting movable clamping sheet and the adapting fixed clamping sheet are adopted to form a guide cylinder to perform adapting transition, and therefore, the problem of difficulty in realizing accurate alignment of the magnetic attraction grooves on the turntable and the shell guide rail can be solved; a rotor is constantly limited by the guide cylinder, so that a transient suspension state of the rotor in a push-in process can be avoided, and therefore, the constant stability of the rotor can be ensured in the push-in process, and accurate alignment of the rotor and a shell can be ensured; the lower end of the rotation shaft of the rotor can be accurately inserted into a shaft hole at the lower end of the shell, so that fully automatic production of the packaging of micro motors can be realized.

Description

technical field [0001] The invention relates to a micro-motor production equipment, in particular to a micro-motor automatic packaging machine. Background technique [0002] Micro motors are commonly used driving devices, and generally use batteries for DC power supply. [0003] The micromotor generally includes a casing, a rotor and an end cover. The lower end of the casing is provided with a shaft hole, and two magnetic pieces with opposite polarities are arranged in the casing. The rotor includes a rotating shaft, a coil winding, a windmill piece and a commutator. The coil winding is installed on In the middle of the rotating shaft, the windmill blade is installed at the lower end of the rotating shaft, and the commutator is installed at the upper end of the rotating shaft. Two power connectors are arranged outside the end cover, and two electric brushes connected with the power connector are arranged on the inner surface of the end cover.

Problems solved by technology

Therefore, when the micro-motor is packaged, it is necessary to accurately align the end cover and the housing, which is also an important reason why the micro-motor package has not been able to achieve full automation.

[0007] Another important reason that makes it difficult to realize fully automatic assembly of micro-motors is that after the housing, rotor and end cover are installed, the two brushes on the end cover must closely and directly cooperate with the commutator on the rotating shaft, that is, two The brushes must be able to hold the commutator tightly. In this way, the two brushes are generally composed of two conductive shrapnels. The two conductive shrapnels have a tendency to be clamped in the middle. Under normal conditions, the two conductive shrapnels are almost clamped together, resulting in During the assembly process of the end cover, it is difficult for the rotating shaft of the rotor to accurately pass between the two conductive shrapnels, so that after assembly, the two conductive shrapnels cannot hold the commutator on the rotating shaft tightly, resulting in more micro-motors after assembly. unqualified
