Component, for heating arrangement that bonded assemblies are heated and for drive the pressure welding power arm to be moved up and down
One actuator；It is described cleaning unit include cleaning support, be formed at cleaning frame upper cleaning table top, located at the dressing table
The cleaning brush group of face top position, the workpiece transfer device, described defeated for driving being at least part laid on the cleaning table top
Send the second actuator with rolls forward, the location structure for positioning position of the workpiece on workpiece transfer device and located at described
Junk structure on workpiece transfer device；The location structure includes the multigroup positioning head group being fixedly arranged on the workpiece transfer device
Part, the positioning head assembly include two along the workpiece transfer device the symmetrically arranged positioning head in axis, the positioning head be L-shaped；
The junk structure includes the junk opening and the filter screen for being removably connected to the junk opening on rear side of two positioning head；
The bonded assemblies are included pressure-welding head and the pressure dissipation part of the pressure welding power arm, original state are connected to by elastic component
When, the pressure dissipation part is located at pressure-welding head lower section, the top position of workbench；The pressure-welding head includes being detachably connected
In the pressure welding power arm bottom upper pressure-welding head body and be fixed on the lower pressure-welding head body of pressure-welding head body on this, be located at
The link slot and welding plush copper of the lower pressure-welding head body lower surface, the welding plush copper include the heat conduction section being arranged in link slot
With the punch section of the lower surface for protruding from the lower pressure-welding head body；The heating arrangement includes adding in the pressure-welding head
Heat pipe and the power supply being powered to heating tube, described heating tube one end are electrically connected with power supply, and the heating tube other end is penetrated to described
In link slot；The heat conduction section heat-conducting layer of outer cladding one of the welding plush copper, the heat-conducting layer outer surface is coated in the link slot
Surface, the heating tube lower end is in contact with the heat-conducting layer upper end；The pressure dissipation part includes plate body, is fixed on the plate
The cushion being fabricated from a flexible material of body lower surface, on plate body first wear mouth, set for what lower pressure-welding head body was passed through
In, for the second cutting ferrule worn mouth and be fabricated from a flexible material that lower pressure-welding head body is passed through, the cutting ferrule detachably connects on cushion
It is connected to described first and wears mouth, a flared section is formed at cutting ferrule top, and flared section upper end extends outwardly to form and the upper pressure-welding head
The ring-type of this mates extends edge；The workbench be provided with one can fore-aft motion soldering pallet, set on the soldering pallet
There is the position limiting structure for spacing workpiece, the position limiting structure is spacing including the first limit assembly on soldering pallet and second
Component, first limit assembly includes two L-shaped positioning convex portions being symmetrically fixedly arranged on soldering pallet, the second limit assembly bag

Displacement drive part.
Pressure dissipation part is provided with the present invention, pressure welding power arm driving pressure-welding head is moved down when carrying out pressure welding to workpiece,
Plate body is in contact with workpiece surface in advance, and pressure-welding head continues to move down conflict to plate body afterwards, afterwards again with workpiece on it is to be welded
Contact is in contact, and butt welding contact is pressed, because pressure-welding head is in contact with plate body so that the part impulse force of pressure-welding head is averaged
Be dispersed on the surface of workpiece so that pressure differential between workpiece entirety and pad reduces, workpiece is not susceptible to become
Shape or damage；The cushion that plate body lower surface is set can reduce the hardness shock between plate body and workpiece, and effectively workpiece is carried out
Protection, prevents the miscellaneous part of workpiece surface to be damaged；The cause not of uniform size of upper and lower pressure-welding head body, lower pressure-welding head body
May pass through the mouth of wearing on plate body, and upper pressure-welding head body cannot be passed through, it is ensured that pressure-welding head when pushing on pressure-welding head body can
Contradict to plate body, it is ensured that stamping press is disperseed；Cutting ferrule wears mouth with respect to first detachably, is conveniently replaceable, by the setting of cutting ferrule,
Effectively prevent from first to wear mouth to wear and tear, abrasion is occurred over just on cutting ferrule, without being changed to plate body, reduce maintenance cost；
The setting of flared section is easy to lower pressure-welding head body to enter in cutting ferrule；Ring-type extends edge can play good delaying to upper pressure-welding head body
Punching is acted on, and further reduces impulsive contact force so that the hardness between pressure-welding head and plate body is clashed into and is changed into flexible shock, effectively prevents pressure
Soldering tip rebounds, and welding effect is more preferable；It is connected by elastic component between pressure dissipation part and pressure-welding head, in pressure welding operation
When, elastic component will compress, and so as to give pressure-welding head upward active force, good cushioning effect be played to pressure-welding head, prevent
Only the stamping press of pressure-welding head is excessive；And during pressure-welding head is moved down, compressive strength gradually increases elastic component, gives pressure welding
Upward active force also gradually increases, and buffering effect is more preferable；
It is in contact with heating tube again after welding plush copper outer cladding heat-conducting layer, more preferably, welding plush copper intensification is more quick for heat-conducting effect,
Improve welding efficiency；And welding plush copper heat conduction section is placed in link slot and overall interior heat-conducting layer cladding, effectively slows down welding plush copper
