Platform, wherein material to be welded for being delivered in the welding platform and overlapping material to be welded by the feeder equipment
To form the place to be welded of material.
Optionally, the feeder equipment uses multiple groups, and every group of feeder equipment is correspondingly arranged a welder and a weldering
Connect platform.
When material to be welded is the busbar in solar photovoltaic assembly, every group of feeder equipment includes at least two confluences
Fixed length cutting mechanism.
As shown in Fig. 2 a, 2b and 2c, the welding system in the present embodiment includes one group of feeder equipment, a welder 23
With a welding platform.This group of feeder equipment includes two busbar fixed length cutting mechanisms of orthogonal setting, i.e., X-axis is converged
Fixed length cutting mechanism 8 and Y-axis busbar fixed length cutting mechanism 9 are respectively used to conveying X-direction busbar 12 and Y direction
Busbar 13.X-axis busbar fixed length cutting mechanism 8 is identical with the structure of Y axis busbar fixed length cutting mechanism 9, only puts
The direction set is different.Welding system in the present embodiment can be by mutually perpendicular two busbars, i.e. X-direction busbar 12
Weld together with Y direction busbar 13.
As shown in Figure 1, busbar fixed length cutting mechanism mainly may include unwinding unit 14, feeding unit 15 and cutting unit
16.Wherein, the busbar that unwinding unit 14 is used to be wrapped carries out uncoiling；Feeding unit 15 is used for the busbar after uncoiling is defeated
It send to welding platform 10；Cutting unit 16 is used to cut off the busbar for being delivered to welding platform 10 according to default fixed length.
The power that its busbar travels forward is from feeding unit 15.The length cut to busbar can be according to required busbar
Length by change feeding unit stroke range realize.The default fixed length of busbar can be 50~650mm.
Optionally, busbar fixed length cutting mechanism further includes stretching unit 17, deburring unit 18 and straightening units 19.Its
In, stretching unit 17 is used to control tension when unwinding unit 14 unreels, to reach the demand of steady feeding；Deburring unit
18 for the busbar deburring after uncoiling；Straightening units 19 are for being straightened the busbar after uncoiling.
Specifically, feeding unit 15 may include two cylinders, and one of cylinder is for clamping busbar, another cylinder
It goes ahead the stroke of a regular length for dragging busbar, unwinding unit 14 can be pulled during dragging simultaneously, so that
The automatic uncoiling of unwinding unit 14.Busbar is set to pass through deburring unit 18 and straightening units 19 during dragging busbar,
So as to complete the deburring and alignment to busbar；Due to the dragging of feeding unit 15, and it is single so that busbar is extended cutting
Member 16, busbar extend the edge of a knife of cutting unit length be exactly required busbar fixed length.
In every group of feeder equipment, the height for the busbar that the feeding unit in each busbar fixed length cutting mechanism is conveyed
Successively differ the thickness of a busbar.It should be noted that the thickness of one busbar of difference mentioned here, for being welded
For the unequal situation of the thickness of the busbar connect, the thickness that wherein height of busbar differs a busbar refers to locating
In the thickness of the busbar of lower section.
In the present embodiment, the busbar of default fixed length is sent out by X-axis busbar fixed length cutting mechanism 8, is then converged by Y-axis
Fixed length cutting mechanism 9 sends out the busbar of default fixed length, wherein Y direction busbar 13 is higher by than X-direction busbar 12
The thickness of one X-direction busbar.Certainly, the difference in height may be greater than a remittance in the feeding process of actual production
Flow the thickness of item.
In the present embodiment, welding platform 10 includes supporting table and the idler wheel 11 being arranged in supporting table.Welder is in
The top of welding platform 10.Idler wheel 11 uses two, and two idler wheels 11 are separately positioned on the two sides of welder.
The present embodiment welding system course of work is as follows: when 15 feeding of feeding unit in busbar fixed length cutting mechanism
When, X-direction busbar 12 is sent in welding platform 10 and is supported on two idler wheels 11, and Y direction busbar 13 is being stretched
It will overlap out with X-direction busbar 12 after certain length, the two forms a crosspoint, which is to converge
The place to be welded of item is flowed, welder 23 is decreased until that thimble directly bears against the cross-point locations of busbar at this time, and thimble 3 is against remittance
The center in the crosspoint of item is flowed, then front shroud 7 declines, and to block the chamber port of chamber, forms the heating of an opposing seal
Chamber, then compressed air is inputted into chamber 22, so that the heat of heating tube 2 can be with the place to be welded of concentrated radiation to busbar, this
Tin coating on sample busbar can melt rapidly and penetrate into and be filled in the gap of two busbar junctions, thus reachable
To the effect being welded and fixed；After waiting 2~5 seconds, stop the injection of compressed air, welding is completed；Then X-axis busbar fixed length is cut out
Mechanism 8 is cut according to default customized cut-off X-direction busbar, front shroud 7 rises, and then the shell of welder rises, thimble 3
Busbar is left, Y-axis busbar fixed length cutting mechanism is welded as a whole further according to default customized cut-off Y direction busbar
Two busbars constitute busbar string 21.
Finally, as shown in figure 3, by the busbar string 21 after the crawl welding of sucker manipulator and near being put into busbar
Pallet 20, then welding system starts the weld cycle of a new round.
It is upwarped due to will cause busbar edge in manual welding process, the surface irregularity, influence after welding are whole
Appearance, and then busbar string is influenced toward the laying on solar photovoltaic assembly.Using the welding system pair in the present embodiment 1
Two busbars are formed by the welding effect figure of T-type busbar and L-type busbar after being welded, after busbar welding
It is good that effect is welded and fixed in pad, and its surfacing is beautiful, does not have edge to upwarp phenomenon, will not influence busbar too
Laying on positive energy photovoltaic module.
As it can be seen that can effectively solve the problem that busbar welds operation bring by hand and converges using the welding system in the present embodiment
An a series of problems, such as stream edge upwarps, welds rear surface out-of-flatness, the welding operating time is long, the busbar after welding will not shadow
Busbar string is rung toward the laying on solar photovoltaic assembly, thus no longer needs to the operation that punching press leveling is carried out to each solder joint, from
And saved the activity duration (it being welded using the prior art, the average speed of welding is about the one busbar string of welding in 20 seconds,
Using the welding system in the present embodiment, speed of welding be can be improved to 3~5 seconds/string), and realize busbar and cut, weld
Integration and automation.
It is understood that embodiment of above is merely to illustrate that the principle of the disclosure and the exemplary implementation that uses
Mode, however the disclosure is not limited thereto.For those skilled in the art, in the essence for not departing from the disclosure
In the case where mind and essence, various changes and modifications can be made therein, these variations and modifications are also considered as the protection scope of the disclosure.
