Detailed description of the invention
In order to be able to be more clearly understood that the above-mentioned purpose of the present invention, feature and advantage, below in conjunction with the second party of the present invention
A kind of dereliction that the embodiment of a first aspect of the present invention is provided by the dereliction grid cell concatenation machine that the embodiment in face is provided
The series-mounting of grid solar cell is further described in detail.
Step 02: the solaode block that multiple obverse and reverses are printed with thin grid line is being sent to the biography of cell laminator
Send band upper proper alignment, the thin polymer film that one side is pasted with a plurality of tin metal line arranged side by side is respectively overlay in each sun
Can the front and back of battery block, it is ensured that be pasted with the one of tin metal line on thin polymer film facing to described solaode
Block.The pillar 1 of dereliction grid cell concatenation machine is supported on the both sides of conveyer belt, and the top board 2 of dereliction grid cell concatenation machine is arranged on biography
Sending the top of band, heating plate 3 is just to conveyer belt；
Step 04: use the cylinder 4 band dynamic pressure plate 5 of dereliction grid cell concatenation machine and heating plate 3 that two sides is covered polymerization
Each solaode block of thing thin film in the range of temperature value is 120-135 DEG C first at a temperature of carry out quick precompressed string
Connecing, the pressure limit of quick precompressed is 0.25-0.35MPa, makes each solaode block be connected in series by thin polymer film；
Step 06: by each solaode block of being connected in series by precompressed in the range of temperature value is 150-160 DEG C
Second at a temperature of carry out lamination welding, the pressure limit of lamination is 0.9-1.1MPa, and make on each solaode block is thin
Grid line gets up with tin metal wire bonding, and now the tin coating on tin metal line realizes metal wire and thin grid line because of fusing
Welding, thin polymer film melts loss, will not remain on solaode block.
In this technical scheme, the both sides of a plurality of tin metal line arranged side by side paste the polymer thin that multi-disc is wide respectively
Film, on each thin polymer film, only one side is sticking veneer, and the sticking veneer of the thin polymer film that each two is adjacent is contrary.Each
Solaode block is serially connected in by precompressed on the sticking veneer of each thin polymer film respectively, the both sides of tin metal line the most arranged side by side
Concatenating multiple solaode block respectively, the solaode block that each two is adjacent is distributed in the two of tin metal line arranged side by side
Side.The sensitive surface of solaode block is front, and shady face is reverse side, and the positive and negative two sides of solaode block represents two respectively
Individual different electrode, after each solaode block concatenated by precompressed carries out lamination welding, each solaode block leads to
Cross and be connected in series one bigger solar panel of composition.
In step 02, described tin metal line is the copper cash that surface is coated with ashbury metal, and employing melting range is 145-155
DEG C low melting point tin alloy as the coating on tin metal line surface, it is possible to decrease the temperature requirement of welding procedure, increase optional
Welding method.
In step 04, the pressure of quick precompressed employing 0.25-0.35MPa can be by solaode block and tin metal line
Temporarily press together so that it is closely, precompressed temperature uses first temperature of 120-135 DEG C that thin polymer film can be made tight in contact
It is fitted in solaode block surface, it is ensured that tin metal line does not comes off before lamination, for solaode block and tin plating gold
Belong to the lamination welding between line ready.
In step 06, pressing-in temp uses second temperature of 150-160 DEG C can make the ashbury metal on tin metal line surface
Coating melts, and finally makes tin metal line weld together with the thin grid line on solaode block surface, uses 0.9-1.1MPa
The lamination pressure of scope can ensure that tin metal line fits tightly in welding process with thin grid line always, prevents rosin joint situation
Occur, improve the welding peeling force of pad.
In any of the above item step, the melting range of thin polymer film is 140-150 DEG C, 120-135 DEG C of scope
Under first temperature environment during precompressed, polymer can be pasted onto because being heated on solaode block, makes the tin metal line will not be from
Solaode block surface comes off, and when the second temperature environment laminated of 150-160 DEG C of scope, thin polymer film can melt automatically
Change, do not affect welding between tin metal line with thin grid line, the outward appearance of solar-electricity block will not be impacted.
