Description
Technical field
The present invention relates to solar cell for space use battle array fabricating technology fields, more particularly to one kind for space sun electricity
Welding method on the braid plate of pond plate.
Background technique
The main power source that solar battery array is widely used as current satellite, main function are to meet satellite phase in orbit
Between electrical energy demands, guarantee star upper mounting plate equipment and payload normal work.As China's aerospace industry develops, spacecraft
Function constantly extending, to the demanded power output of solar battery array, to light weight, collection is small in size, facilitates spacecraft
The solar battery array technology for the superelevation specific power for carrying and being conveniently replaceable has urgent need.
With the development of solar battery array technology, the folding flexible solar cell wing is shown one's talent.To meet spacecraft
The use demand of bearing power and solar wing transmission envelop, the flexible solar cell plate of large area need face-to-face in transmitter section
It compresses and collapses in dedicated collection case.When collapsing compression, battery circuit part is that fitting compresses completely face-to-face, between plate not
Stay any gap.Typical round cross section wire is relatively large in diameter, diameter of wire 0.94mm, it is difficult to be met plane and be collapsed the need compressed
It wants, therefore develops the flat special cable thickness of novel copper free wire braiding structure and reach 0.2mm.Cable needs to be laid in sun battle array
On substrate, the Joining Technology of circuit needs onboard to carry out.
Welding in conventional panels between conducting wire uses soldering, belongs to mature technology, 8~10 year service life of high rail and low rail 3~5 years
Service life environment has been applied successfully, but 15 year service life of low rail there is no application.According to 15 years orbital thermal environments of operation and mechanical environment need
It asks, for braid material and design feature, after comparing a variety of welding techniques, final determine uses electric resistance welding pair
Weldering mode.Electric resistance welding can be divided into butt welding, parallel weldering and step weldering several ways again.Due to by flexible solar cell array manufacturing process
Limitation, welding need to be carried out onboard, and parallel weldering and step weldering are the most suitable, but welding quality and stability are not so good as butt welding again, therefore
Select butt welding mode.
As shown in Figure 1, flexible solar cell array busbar and the welding of cable on plate need to carry out on substrate, wherein substrate
It is insulating materials, and traditional butt welding is not suitable for welded piece on one side the case where insulant, traditional butt welding mode is obviously not
Suitable for this, in the case where not changing traditional butt welding mode, if thinking the welding of cable on completion busbar and plate, can only select
It is destroyed to substrate, so needing to design the butt welding mode welded on novel suitable plate.
Summary of the invention
It is welded on a kind of braid plate for solar cell for space use plate the technical problem to be solved by the present invention is providing
Flexible base board can be pushed into plate electrode so during the welding process using plate electrode by one of electrode by method
Lower section, welded part are placed on above plate electrode, then realize more convenient, more efficient welding.
The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that
Welding method on a kind of braid plate for solar cell for space use plate includes at least following steps:
Step 101, preparation, according to actual needs, select first electrode, busbar, establishment cable, flexible base board,
Second electrode；The second electrode is plate electrode；
Flexible base board is arranged in the lower section of the establishment cable in step 102, stays between establishment cable and the flexible base board
There is the pore belt of width A；The width A is not less than the thickness of second electrode；
Second electrode is inserted into pore belt by step 103；
Step 104 is arranged successively first electrode, busbar, establishment cable, second electrode, flexible base board from top to bottom；
Step 105, selection welding parameter are welded, and resistance spot weld is formed between busbar and braid.
The advantages and positive effects of the present invention are:
It, so during the welding process can using plate electrode by one of electrode by using above-mentioned technical proposal
With by below flexible base board push-in plate electrode, welded part is placed on above plate electrode, is then realized more convenient, more efficient
Welding.Simultaneously: since the present invention is using electric resistance welding on braid plate, providing effective work for solar battery array technology of preparing
Process.Relatively previous tradition is to welding technology, and it solves the problems that butt welding is limited and cannot achieve by welding region, adapts to
In weld gap≤5mm resistance welding.Since cable can not use soldering on traditional braided plate, this patent is braided
Cable has started a kind of new welding manner on plate.
