Micro motor automatic packaging machine

Abstract

The invention relates to a rotor and housing assembly device of a micro-motor automatic packaging machine, including a frame, a housing guide rail, a turntable, a stepping drive device and a rotor pushing mechanism, and a plurality of semicircular cross-sections are arranged at equal intervals on the circumference of the turntable The magnetic suction groove; the rotor pushing mechanism includes a push-in lifting mechanism, a rotor push rod, a transfer lifting mechanism, a transfer lifting seat, a transfer base plate, a transfer fixed clip, a transfer movable clip and a transfer cylinder. Due to the transfer of the movable clip and the transfer of the fixed clip to form the guide cylinder for transfer and transition, the problem of difficult alignment between the magnetic groove on the turntable and the guide rail of the housing is solved, and the rotor is always under the limit of the guide cylinder. , to avoid the momentary suspended state of the rotor during the push-in process, to ensure that the rotor remains stable during the push-in process, to ensure that the rotor and the housing are accurately aligned, and the lower end of the rotor shaft can be accurately inserted into the shaft hole at the lower end of the housing, so that the micro The packaging of the motor enables fully automated production.

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
