Problems solved by technology
In the existing technical scheme, the glue coating of the rotor is a separate process step, which is mainly completed by supplying glue to the dispensing head through the pressure barrel, and then manually operating the dispensing head for dispensing. In this way, not only the workload is large , time-consuming and laborious, and because the thick glue is easily mixed with air when it is put into the pressure barrel, the glue will occasionally be emptied when it is discharged through the pipeline, so the dispensing quality cannot be guaranteed

The invention discloses an automatic dispensing device for rotor slot coating glue, and belongs to the field of micro-motor production. The device comprises a rotor positioning slot body, a pluralityof glue pressure barrels and a plurality of glue injection assemblies arranged around the rotor positioning slot body, wherein a rotor upward sliding push rod is arranged at the bottom of the rotor positioning slot body; each glue injection assembly comprises a glue pre-storage bin, a glue extrusion push rod and a glue induction elastic connecting rod; a glue guide hole communicating with the rotor positioning slot body and a glue inlet communicating with a glue pressure barrel are formed in the side wall of each glue pre-storage bin, and the glue guide hole is located above the glue inlet; the glue extrusion push rods are arranged at the bottoms of the glue pre-storage bins to movably extrude the glue in the glue pre-storage bins upwards; and the glue induction elastic connecting rods arearranged at the tops of the glue pre-storage bins to movably shield the glue guide holes. According to the technical scheme, the dispensing of the rotor slot coating glue can be automatically completed through a mechanical mechanism, and the dispensing quality of the rotor slot coating glue can be guaranteed.
Description
technical field [0001] The invention relates to the field of micro-motor production, in particular to a rotor automatic groove coating device. Background technique [0002] In the current production process of DC motors, the commutator and coil are mainly welded by spot welding. In this way, during daily use, it is very likely that the solder joints will be weak, poor contact or even desoldering due to vibration and high temperature. . In response to this situation, the means of sealing (dot) glue (that is, rotor coating groove glue and neck glue) is generally used in the industry to avoid the occurrence of this problem. In the existing technical scheme, the glue coating of the rotor is a separate process step, which is mainly completed by supplying glue to the dispensing head through the pressure barrel, and then manually operating the dispensing head for dispensing. In this way, not only the workload is large , Time-consuming and laborious, and because the thick glue is ...
