Automatic assembling machine for electric brush of micro-motor end cover

Abstract

The invention relates to an automatic assembling machine for electric brushes of a micro-motor end cover. The automatic assembling machine comprises a rack, a left electric brush pressing mechanism, a right electric brush pressing mechanism, a left electric brush first glue dispensing mechanism, a right electric brush first glue dispensing mechanism, an end cover conveying mechanism, a left electric brush queuing mechanism, a right electric brush queuing mechanism, a left electric brush conveying and positioning mechanism, a right electric brush conveying and positioning mechanism, a left electric brush grabbing and inserting mechanism and a right electric brush grabbing and inserting mechanism. Starting from positioning and orientation of end covers, the end cover is tidily arranged in a fixing direction through an end cover tidying device, then the end covers are conveyed through end cover conveying rails in combination with an end cover poking mechanism to ensure that the end covers are accurately conveyed to a designated position and the fixing direction is kept unchanged, and finally subsequent processes such as electric brush insertion, pressing and glue dispensing are conducted. The problems that the end covers are difficult to position and cannot be oriented in the conveying and operating process and the operating accuracy and stability cannot be guaranteed are solved, the full-automatic assembling of the end cover electric brushes of a micro-motor is realized, the production efficiency is improved and the production cost is reduced.

Description

technical field [0001] The invention relates to an assembly device of a micro-motor, in particular to an automatic brush assembly machine for the end cover of a micro-motor. Background technique [0002] The end cover of the micro-motor includes a cover body, the cover body has two parallel straight sides, and two protrusions and two brush slots (left brush slot and right brush slot) are symmetrically arranged on the cover body. The brush generally includes a plug arm, a brush arm and a carbon brush block. One end of the brush arm is connected to one end of the plug arm, and the brush arm is perpendicular to the plug arm, and the carbon brush block is arranged at the other end of the brush arm. [0003] Restricted by the structure of the end cap and the brush, at present, the assembly of the brush on the end cap of the micro-motor is still a manual or semi-automatic operation. In the case of semi-automatic operation, the end cap of the micro-motor The brush assembly is divi...

Problems solved by technology

[0003] Restricted by the structure of the end cap and the brush, at present, the assembly of the brush on the end cap of the micro-motor is still a manual or semi-automatic operation. In the case of semi-automatic operation, the end cap of the micro-motor The brush assembly is divided into several sections, namely the plugging brush section, the pressing brush section, the first glue dispensing section, the second glue dispensing section, etc., and adopts flow operation, although some pressing devices and dispensing devices are used. , but the degree of manual intervention is still very large, and a worker is required to perform corresponding operations on each section

At present, the assembly method of this micro-motor end cover has the following disadvantages: (1) It requires a lot of manpower; (2) It has low production efficiency; society, invisibly increasing the huge cost

[0004] The main reason why the current micro-motor end caps cannot be assembled automatically is that it is difficult to accurately position the end caps during the micro-motor transportation process, and it is difficult to arrange the brush slots on all end caps in a fixed direction. When the end cap is operated, it is impossible to ensure that the end cap will not shift, so it is impossible to perform precise fixed-point operation on the end cap; another important reason is that the brushes cannot be neatly arranged, and the brushes cannot be delivered to the designated position one by one, and Keep the arm of the brush down
