In the one embodiment provided in the application, localization tool 105 is made to go upward to the operation of armature positioning device first
Position.Here operating position should enable locating piece 202 limit the Anterior-Posterior of armature 102, and washer 201 can limit
The left and right degree of freedom of armature 102, plane pressure head 208 can limit the freely up and down degree of armature 102.Then, 208 points of plane pressure head
Dynamic downlink, touches and original position is returned to after 102 surface of armature is pre-positioned.Locating piece 202 moves ahead to connect with 102 front plan of armature
It touches.At this point, due to armature 102 be it is movable, armature 102 contact locating piece 202 when can with the movement of locating piece 202 and
Adjust the position on front-rear direction.Then, the cylinder 206 of link mechanism 205 moves ahead, and drives left and right two panels washer 201 to close
The movement of mutual direction, until the relative distance of two panels washer 201 and the width of armature 102 are mutually agreed with, so as to play limit it is electric
The effect of 102 or so degree of freedom of pivot.
S400：Armature 102 is welded according to the position after adjustment.
Wherein, it is using laser welding process that welding is carried out to armature 102.Laser welding is swashing using high-energy density
A kind of high-efficiency and precision welding method of the light beam as heat source.Laser welding may be used continuous or pulse laser beam and realize.Laser
The principle of welding can be divided into heat-conduction-type welding and Laser Deep Penetration Welding.
The principle of heat-conduction-type laser welding is：Workpiece to be processed surface, the heat of workpiece surface are heated by laser emission
Amount is internally spread by heat transfer.The laser such as width, energy, peak power and repetition rate by controlling laser pulse are joined
Number, melts workpiece, forms specific molten bath.After material cooling to be melted, weld seam is formed.
Laser Deep Penetration Welding is generally completed using continuous laser light beam.Under the laser irradiation of high power density, material steams
It sends out and forms hole.The outer wall of heat from this high temperature vestibule passes out, and makes the metal molten of encirclement vestibule surrounding.In hole
It is filled in the high-temperature steam that light beam irradiation lower opening cavity wall material continuous evaporation generates.Light beam constantly enters hole, the material outside hole
Material is continuously flowing.As light beam moves, stable state of the hole always in flowing.It is stayed after removing in molten metal filling hole
Under gap and cooled and solidified, so as to form weld seam.
The application provide one embodiment in, the left and right degree of freedom and Anterior-Posterior of armature 102 be defined with
Afterwards, 208 times 102 surfaces of press contacts armature of plane pressure head, fix 102 position of armature.Pass through the semicircle of washer 201 using laser
V notch v 209 welds armature 102, makes armature 102 and iron core parallel, and is maintained at the mechanical location center of iron core.
The dynamic iron loudspeaker armature welding method that the application provides realizes the automatic positioning of armature, solves and is positioned manually surely
The problem of qualitative and accuracy is poor improves the yields and production efficiency of dynamic iron loudspeaker.
