Glue filling device of permanent-magnet synchronous-motor rotor assembly and flue filling method of glue filling device

Abstract

The invention discloses a glue filling device of a permanent-magnet synchronous-motor rotor assembly and a flue filling method of the glue filling device. The glue filling device comprises a rotor assembly fixing device, a positioning fixture, a glue filling device body, a glue storing device and a glue filling device stand. The glue filling method includes the steps of 1), adjusting the positioning fixture in position; 2), fixedly installing a front end plate on the positioning fixture; 3), fixing the rotor assembly to the front end plate and a rotor support through a positioning tooling; 4),starting a triaxial manipulator; 5), driving the triaxial manipulator to move to a glue filling point according to relative positions of the glue filling point in a magnetic steel notch in the rotorassembly and the positioning point; 6), driving a first transfer pump and a second transfer pump to fill glue liquor to a glue mixture tube and an injection needle for glue filling. With the method, precision in glue filling can be effectively improved, glue filling efficiency can be effectively improved, and the glue filling method is simple in operation.

Description

technical field [0001] The invention relates to the technical field of glue filling for motor rotor components, in particular to a glue filling device and a glue filling method for a rotor component of a permanent magnet synchronous motor. Background technique [0002] At present, the assembly method of the permanent magnet magnet in the rotor assembly of the permanent magnet synchronous motor is: reserve a slot on the rotor punch, and when the punch is stacked into an iron core, a magnet groove for assembling the magnet is formed; in order to reduce the assembly Difficulty, the gap between the magnet and the notch is matched, and glue is used to fix it during assembly to prevent the magnet from vibrating in the slot when the motor is running. The glue used can be epoxy AB glue, anaerobic glue, etc., and the filling method is mostly manual. Glue manually. [0003] However, the above-mentioned fixing method has the following technical problems: 1. A small amount of air bubbl...

Problems solved by technology

[0003] However, the above-mentioned fixing method has the following technical problems: 1. A small amount of air bubbles are wrapped by the glue during the potting process, and remain in the glue after curing, which affects the bonding strength between the magnetic steel and the notch; 2. During manual filling, The control of the amount of glue used is not accurate, and there will be more scraping and less replenishment in the later stage; 3. Glue overflow caused by manual potting, cleaning of the work surface and the environment; 4. The production efficiency of manual potting is low, and the production capacity is severely limited
