Automatic armature sheet welding equipment

Abstract

The invention discloses automatic armature sheet welding equipment which comprises an automatic welding mechanism. The automatic welding mechanism comprises a positioning assembly, a rotary pressing assembly and a welding assembly; the welding assembly is arranged at one end of the positioning assembly; the rotary pressing assembly is arranged on one side of the positioning assembly; the positioning assembly comprises a positioning seat, a bearing seat installed on the positioning seat, and a welding supporting seat rotatably installed on the bearing seat; a limiting column is arranged on the welding supporting seat; a clamping groove is formed in the limiting column; the rotary pressing assembly comprises a servo motor capable of sliding and a rotary pressing block fixedly installed on an output shaft of the servo motor; the rotary pressing block is arranged over the welding supporting seat; the lower surface of the rotary pressing block is provided with a limiting groove matched with the limiting column; a clamping block matched with the clamping groove is arranged in the limiting groove; the welding assembly comprises a welding gun; and the welding gun is arranged right opposite to the welding supporting seat. The automatic armature sheet welding equipment provided by the invention can prevent an armature sheet from sliding, so that the welding qualification rate is increased.

Description

technical field [0001] The invention relates to the technical field of motor production equipment, in particular to an automatic armature piece welding equipment. Background technique [0002] Printed winding motor is a micro motor with special armature winding structure, referred to as printed motor. Its armature winding is printed on the clad copper foil board by corrosion method, electrochemical deposition method and electrochemical transfer method, or it is formed by punching copper foil and then stacked and glued. The armature winding is composed of two or more even-numbered layer printed windings and interlayer insulating sheets. The windings of each layer are welded into a closed loop according to a certain connection method, and the entire armature is disc-shaped; at present, the welding of the armature sheet guide bar Most of the process is manual welding, that is, the armature piece is fixed in the fixture, the equipment drives the fixture to rotate, and then the ...

Problems solved by technology

The armature winding is composed of two or more even-numbered layer printed windings and interlayer insulating sheets. The windings of each layer are welded into a closed loop according to a certain connection method, and the entire armature is disc-shaped; at present, the welding of the armature sheet guide bar The process is mostly manual welding, that is, the armature piece is fixed in the fixture, the equipment drives the fixture to rotate, and then the welding torch is aimed at the outer ring for welding. This method often causes missing welding, virtual welding, and over-welding of the guide bar. Occurs, making product quality uncontrollable, poor consistency, and low work efficiency
