Abstract
The invention relates to the dispensing technology field in motor manufacture, and more particularly to a dispensing method for prolonging the service life of a rotor. The method comprises the following steps: (1) preheating: heating high permeability one-component epoxy glue to a temperature of 70 DEG C, and preheating a rotor to a temperature of 80 to 90 DEG C; (2) dispensing: using a dispersion glue machine to drip the one-component epoxy glue on a commutator hook of the rotor uniformly and accurately; (3) solidifying: solidifying the glue thoroughly in a baking oven of 130 DEG C; (4) taking out the rotor for preparation: dripping varnish on solenoid of the stator, and cleaning superfluous varnish on the surface for entering into a next operation. Compared with the prior art, in the present invention, the special high permeability one-component epoxy glue replaces nonsaturated polyester sealing paint. The glue is dripped on the commutator of the rotor, thus the service life of product is effectively prolonged.
Description
Technical field
The present invention relates to the dispensing technology field in the motor manufacturing, is a kind of dispensing method that improves rotor life specifically.
Background technology
Traditional rotor is reinforced insulation and gaining in strength after winding line, can online bag and commutator place, and splash into unsaturated polyester (UP) varnish or seal lacquer and be cured again.But because the limitation of polyester lacquer itself, it can produce bigger shrinkage stress by liquid state in the process of solid-state conversion, is not suitable for the comparatively violent and thinner electric tool rotor of enamelled wire diameter of vibration.
Summary of the invention
The present invention adopts a kind of special high osmosis single-component epoxy glue to replace unsaturated polyester (UP) to seal lacquer for overcoming the deficiencies in the prior art, drops in the commutator place of rotor.
For achieving the above object, design a kind of dispensing method that improves rotor life, it is characterized in that: (1) preheating: high osmosis single-component epoxy glue is heated to 70 ℃, rotor is preheating to 80-90 ℃; (2) some glue: single-component epoxy glue is evenly dropped in rotor commutator hook place exactly with point gum machine; (3) solidify: in 130 ℃ baking oven, glue is thoroughly solidified; (4) taking-up is standby: the place splashes into varnish at rotor line bag, and cleaning shows that unnecessary varnish changes next procedure over to.
The present invention compares with prior art, adopt a kind of special high osmosis single-component epoxy glue to replace unsaturated polyester (UP) to seal lacquer, drop in the commutator place of rotor, this glue has good flowability when 70 ℃ of left and right sides, can infiltrate rapidly between the intensive enamelled wire and fill, and this glue has stronger heat-resisting ability and higher-strength after fully solidifying, can resist high-strength mechanical impacts, life of product was brought up to 700 hours by original 70 hours, had effectively improved the useful life of product.
Embodiment
Below the present invention is described further.
Adopt following processing step that the rotor line is carried out a glue:
Preheating: high osmosis single-component epoxy glue is heated to 70 ℃, rotor is preheating to 80-90 ℃;
Point glue: single-component epoxy glue is evenly dropped in rotor commutator hook place exactly with point gum machine;
Solidify: in 130 ℃ baking oven, glue is thoroughly solidified;
Take out standby: the place splashes into varnish at rotor line bag, and cleaning shows that unnecessary varnish changes next procedure over to.
Claims (1)
1. a dispensing method that improves rotor life is characterized in that: (1) preheating: high osmosis single-component epoxy glue is heated to 70 ℃, rotor is preheating to 80-90 ℃; (2) some glue: adopt dispensing method to drop in rotor commutator hook place in single-component epoxy glue; (3) solidify: in 130 ℃ baking oven, glue is thoroughly solidified; (4) taking-up is standby: the place splashes into varnish at rotor line bag, and cleaning shows that unnecessary varnish changes next procedure over to.
