Product Description

Function: Separating the cell string from the glass, use grip to lift cell strings to a certain height, then weld the panel busbar in the front, middle, and tail simultaneously. Roll feeding bus bar can bend U and L type upwards.

The raw material specification
   Cell specification: 166/9BB busbar distance 16.79mm or M10 182/10BB or M12/12BB (other cell is optional, which can be upgraded with additional cost, Standard machine only with one type cell jig)

   Compatible Solar Cell Specification: 156mm-210mm / 5bb-12bb
(DH180H can be upgraded to other different solar cell types with additional cost. Same cell size with different busbar quantity, only need to replace the base plate. Different cell size need to replace the welding head, base plate etc. this machine compatible Cell from156mm to 210mm with 5bb-12bb

   Module specification:
A.    156-180 cells:
 6 strings x10 half pieces x 2,   6 strings x 11 half pieces x 2,
6 strings x12 half pieces x 2,   6 strings x 13 half pieces x 2,
the interval between cells is - 0.5-4mm, and the string spacing is 1-6mm;
B.    210 cells:
6 strings x 10 half chips x 2,   6 strings x 15 1/3 Cut cells x 2,
the interval between chips is 1-4mm, and the string spacing is 1-6mm;
C.    210 cells:
5 strings x 10 half Cells x 2,   5 strings x 15  1/3 Cut cells x 2,
the interval between pieces is 1-4mm, and the string spacing is 1-6mm;
(bypass welding function is optional, and the distance between bypass busbars is no less than 10 mm (4 mm busbars))

   Glass specification:1630-2500 length x 980-1400 width

   Busbar specification: Bus bar is in roll feeding and automatic cutting, thickness 0.18-0.45mm, width4, 5 6 8mm, roller weight 13Kg.

   It has the function of busbar drilling, which can be turned off.

   The shape drawing of the half assembly bus bar is as follows (the actual version drawing provided by the buyer shall prevail)

Main technical parameters:
(1)   Cycle: 20s for conventional version, 25s for bypass welding (glass exchange rate of transmission line is 3.5s/piece, thickness of busbar belt ≤ 0.35mm) Fragment rate: 0.2 (as per pcs)
(2)   Fragment rate :<0.2‰(as per pcs)
(3)   Soldering method: electromagnetic
(4)   Height of module in & out: 950 20mm
(5)   Lead busbar angle and deviation:90° deviation ≤2°
(6)   The overlap area of bus bar ≥80%, and the deviation is within ± 1 mm
(7)   Overlap deviation of bypass bus belt: ± 1mm
(8)   Post welding tensile force: the welding tension of bypass busbar belt is 4 * 4 area ≥ 20n, 4 * 6 area is ≥ 25N, 6 * 6 area is ≥ 30n (spraying flux), and the pulling force between busbar and welding strip is ≥ 5N / mm (spraying flux)
(9)   The maximum allowable deviation of component inflow: glass center deviation < 30mm
(10) Overall yield ≥ 98% (according to the unit, the typesetting accuracy of components flowing into the busbar welding machine should be within ± 0.5mm, and the standard of multi main grids is the same)
(11) Maintenance rate ≥ 98%
(12) The accuracy of secondary string arrangement is ± 0.25mm
(13) The assembly line in front of the welding machine must have the function of normalization
