Abstract
The utility model discloses it is inaccurate easily to cause the injection position when spraying the scaling powder to prior art scaling powder injection apparatus, it is inhomogeneous to make the scaling powder spray, waste the not enough of scaling powder, the utility model provides a weld and take scaling powder coating unit, it includes the scaling powder groove, still include the coating roll and weld the preceding dancer rools in area, weld area back dancer rools, the scaling powder sets up at the scaling powder inslot, preceding dancer rools setting is in the front upper place in scaling powder groove, back dancer rools setting is in the back upper place in scaling powder groove, the trend of welding the area by preceding dancer rools and back dancer rools adjustment and height and make the coating roll take tangent the connection with welding, weld the lower surface in area by the coating roll with the scaling powder coating, adopt the utility model discloses the scaling powder coating unit of structure then utilizes the tangent line principle with scaling powder coating to the reverse side that welds the area owing to adopt the coating roll to draw the scaling powder, only makes and welds the reverse side coating scaling powder in area, and do not have the scaling powder in its front, prevents that the scaling powder from blockking up the sucking disc hole.
Description
Technical field
The utility model relates to technical field of solar cell manufacturing, particularly relates to the welding scaling powder apparatus for coating of series winding welding solar battery sheet.
Background technology
The welding sequence of solar battery sheet is one of critical process during solar module is produced, it not only has strict requirement to the quality of connection between cell piece and welding, and also have very high requirement to the cleanliness factor in cell piece front, must not the impurity such as residual flux in the front of cell piece, to avoid the daylighting effect affecting cell piece.In the series winding welding process of solar battery sheet, the positive and negative of adjacent two cell pieces relatively, complete connection by same welding.As shown in Figure 1, namely when welding 5 is welded with the reverse side 3 of first piece of cell piece 1 by its upper surface 6, then welded with the front 2 of second piece of cell piece 1 by the lower surface 4 of welding 5, welded with the front of first piece of cell piece by the lower surface of another welding 5 simultaneously, welded with the reverse side of second piece of cell piece by the upper surface of this welding.When welding cell piece, need surface spraying scaling powder that is surperficial at cell piece with spray equipment and welding, adopt scaling powder injection apparatus at cell piece or scaling powder surface prefluxing in prior art, when adopting injection apparatus spray scaling powder, the bad accurate grasp in position of scaling powder, and easily sputter, that causes scaling powder waste or scaling powder to be coated with is uneven.
Utility model content
The purpose of this utility model easily causes eject position inaccurate when being and spraying scaling powder for employing prior art scaling powder injection apparatus, scaling powder is made to spray deficiency that is uneven, waste scaling powder, a kind of scaling powder apparatus for coating is provided, adopts this device can be coated with scaling powder equably.
The purpose of this utility model is achieved by the following technical solution:
A kind of welding scaling powder apparatus for coating, comprise flux bath, also comprise dancer rools after dancer rools before applicator roll and welding, welding, scaling powder is arranged in flux bath, front dancer rools is arranged on the front upper place of flux bath, rear dancer rools is arranged on the back upper place of flux bath, adjusts the trend of welding and height and makes that applicator roll and welding are tangent to be connected, by applicator roll, scaling powder is coated on the lower surface of welding by front dancer rools and rear dancer rools;
The lower end of applicator roll is immersed in scaling powder;
The circumferential surface of applicator roll is provided with scaling powder and receives layer;
The described layer that receives is coating or weaving face fabric or the coating being provided with Small Holes;
Also comprise dip roll, dip roll is all or part of to be arranged in scaling powder, and applicator roll is arranged on the top of dip roll, to be in transmission connection dip roll and applicator roll, and to carry scaling powder by scaling powder conveyer belt;
The conveyer belt that described conveyer belt is filter cloth or filters.
Adopt the scaling powder apparatus for coating of the utility model structure, extracting scaling powder owing to adopting applicator roll then utilizes tangent principle scaling powder to be applied to the reverse side of welding, only make the reverse side coating scaling powder of welding, and there is no scaling powder in its front, prevent scaling powder from blocking sucker hole.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
As depicted in figs. 1 and 2, following scaling powder apparatus for coating is preferably adopted to be welding coating scaling powder:
It comprises flux bath 21, applicator roll 24, and welding 5 is connected with the circumference of applicator roll is tangent, holds scaling powder 22 by flux bath 21, by applicator roll, scaling powder is coated on the lower surface of welding.Scaling powder in the paint roller of applicator roll can be obtained by two kinds of methods, the first is in flux bath, arrange a dip roll 23, be connected by scaling powder conveyer belt 26 between applicator roll 24 with dip roll 23, dip roll is arranged in scaling powder 22 wholly or in part, or can directly by applicator roll partial immersion in scaling powder.Applicator roll is driven by power set and rotates.The surface that preferred scaling powder conveyer belt 26 is relative with welding 5 is provided with aperture, can hold scaling powder like this, is conducive to the transmission of scaling powder, makes welding obtain the scaling powder of q.s.When only arranging applicator roll, when not arranging dip roll, one deck scaling powder can be set on the surface of applicator roll and receive layer, this receives layer can be the weaving face fabric being provided with Small Holes, as filter cloth or filter conveyer belt, having good scaling powder absorbent properties, also can be that surface arranges foraminate rubber strip.In order to adjust the distance between welding and applicator roll, the front of applicator roll be positioned at be provided with above welding before dancer rools 28, the rear of applicator roll be positioned at be provided with above welding after dancer rools 29, the height of front dancer rools and rear dancer rools is all adjustable.During use, provide welding 5 by welding generator 27, adjusted the height of welding by front dancer rools 28 and rear dancer rools 29, make itself and applicator roll tangent, applicator roll, is applied to the lower surface of welding by scaling powder.Applicator roll receives the width of width more preferably greater than welding of layer, is conducive to scaling powder coating so evenly.
