Abstract
The invention relates to a tensile strength test tool of an electrode/welding point of a cell. The tensile strength test tool comprises an upper panel, a base and a silicon rubber plate, wherein the upper panel is arranged on the upper surface of the base; one end of the upper panel is hinged to the base and the other end of the upper panel is fixed on the base through a nut; the upper panel is provided with a leading-out groove corresponding to a grid line of the cell; the cell is arranged between the upper panel and the base; an electrode of the grid line of the cell and a welding belt of the welding point are guided out from the leading-out groove; and the silicon rubber plate is arranged on the lower surface of the base. Compared with the prior art, the tensile strength test tool has the advantages of simplicity in operation, manpower cost saving, high efficiency and the like.
Description
Technical field
The present invention relates to a kind of cell piece test tool, especially relate to a kind of frock for cell piece electrode/mechanical properties test.
Background technology
Crystal silicon solar battery component is encapsulated behind the welding series and parallel by a plurality of cell pieces and forms.Welding quality and the assembly quality of cell piece are closely bound up.If rosin joint, sealing-off, solder skip then can directly affect the overall performance electrical performance of battery component, the unfailing performance in can using the assembly later stage simultaneously cause hidden trouble, so need in the assembly production regularly the welding quality of cell piece is checked.The most key in the welding quality is the tensile strength (both having welded the peel strength between rear electrode and interconnecting strip) of cell piece electrode/solder joint.
The frock that adopts in cell piece electrode/mechanical properties test at present is comprised of the two rings epoxy resins plate that area is slightly larger than the cell piece area, wherein has 1 length, width on upper epoxy resin board surface all greater than the groove of welding length and width degree.Concrete operating process, that the cell piece after the welding is sandwiched in up and down in the middle of the two rings epoxy resins plate, welding passed from groove with tautness meter be connected, two hand bracelets of one human epoxy resins plate, other people's level is afterburning gradually backward, and the numerical value that obtains during from the cell piece sur-face peeling of record interconnecting strip.The defective that this frock exists has two aspects, the one, owing to fixedly be to be delivered to again on the cell piece by the people for forcing in the epoxy resin board surface to cell piece in the test, because the frangible in addition people of cell piece self is that the dynamics size that applies is wayward, the cell piece so can often crush in the test causes the cell piece waste.The 2nd, test needs two people to assist to finish, and the personnel that cause waste.
Summary of the invention
Purpose of the present invention be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of simple to operate, save human cost, cell piece electrode that efficient is high/mechanical properties test tool.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of cell piece electrode/mechanical properties test tool, comprise top panel, base and silicane rubber plate, described top panel is located at the upper surface of base, one end of top panel is articulated in base, the other end is fixed on the base by nut, and top panel offers the lead-out groove corresponding with the grid line of cell piece, between cell piece plate located in the above and the base, the electrode at cell piece grid line place and the welding of solder joint are drawn from lead-out groove, and described silicane rubber plate is located at the lower surface of base.
One end of described top panel is hinged by hinge hinge and base, and the other end is fixed on the base by butterfly nut.
Described silicane rubber plate is adhered to the lower surface of base by cementing agent.
Described top panel and base are respectively stainless steel top panel and stainless steel base.
Compared with prior art, the present invention has the following advantages:
First: because the test cell sheet is to fix by the butterfly nut on the adjusting tool, so avoided applying the improper cell piece fragmentation that causes of dynamics control because of the people.
Second: Fixture Design has top panel corresponding for different graphic (being different size, different grid line) and can be for convenience detach, so can save the frock material cost.
The 3rd: frock fixedly be to realize by the friction force between frock own wt and lower surface silicane rubber plate and glass table top, so can save 1 staff, namely raise the efficiency.
Description of drawings
Fig. 1 is main TV structure synoptic diagram of the present invention;
Fig. 2 is the structural representation of looking up of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
As depicted in figs. 1 and 2, a kind of cell piece electrode/mechanical properties test tool, comprise top panel 1, base 2 and silicane rubber plate 3, top panel 1 and base 2 all adopt stainless steel to make, top panel 1 is located at the upper surface of base 2, one end of top panel 1 is articulated in base 2 by hinge hinge 4, this hinge hinge 4 at first is welded to it on top panel 1 when mounted, then the hexagonal nut point is welded on the base 2, passes hinge hinge 4 by the screw that cooperates with hexagonal nut and screw in the hexagonal nuts and be fixed.The other end of top panel 1 is fixed on the base 2 by butterfly nut 5, top panel 1 offers the lead-out groove corresponding with the grid line of cell piece 6, between cell piece plate 1 located in the above and the base 2, the electrode at cell piece grid line place and the welding of solder joint are drawn from lead-out groove, and silicane rubber plate 3 is adhered to the lower surface of base 2 by cementing agent.
In actual mechanical process, at first this frock is placed on the glass or marble countertop of level, open top panel, soldered cell piece is placed on the base, the welding that is welded in grid line place, cell piece surface is passed from the lead-out groove of top panel, and the top panel that closes makes stressed clamping cell piece between top panel and the base by regulating butterfly nut, again the welding termination is fixed on the tautness meter anchor clamps, can be tested.
Claims (4)
1. cell piece electrode/mechanical properties test tool, it is characterized in that, comprise top panel, base and silicane rubber plate, described top panel is located at the upper surface of base, and an end of top panel is articulated in base, and the other end is fixed on the base by nut, top panel offers the lead-out groove corresponding with the grid line of cell piece, between cell piece plate located in the above and the base, the electrode at cell piece grid line place and the welding of solder joint are drawn from lead-out groove, and described silicane rubber plate is located at the lower surface of base.
