The spring roller that is used for coating equipment that the utility model provides; Comprise roller bearing and be set in the spring on the said roller bearing; Said spring comprises a plurality of contacting parts of when the spring roller rolls, contacting with the back electrode of silicon chip and discontiguous a plurality of away from portion with the back electrode of said silicon chip on silicon chip; The diameter of said contacting part is greater than said diameter away from portion, and said contacting part and said is provided with along the axis of said roller bearing away from portion at interval.
As preferably, said contacting part and said evenly is provided with along the axis of said roller bearing away from portion at interval.
As preferably, saidly be locked on said roller bearing away from portion.
As preferably, adjacent is said away from also being provided with transition part between portion and the said contacting part.
As preferably, adjacent two identical away from the distance between adjacent two back electrodes on the distance between the portion and the silicon chip.
Preferred as further, said number away from portion equals the bar number of the back electrode on the said silicon chip.
As preferably, each said away from portion along the length of said roller bearing less than the length of each said contacting part along said roller bearing.
Preferred as further, the number of coils sum of each said contacting part is 22-29.
The utility model also provides a kind of coating equipment, and it comprises aforesaid spring roller.
Spring roller and coating equipment that the utility model is described to be used for coating equipment compared with prior art have following beneficial effect:
1, during plated film, the spring roller aim at the back electrode on the silicon chip away from portion because spring does not contact with back electrode away from the spring ring of portion, do not have electric current to pass through between the two, back electrode can be by spring ring copper facing, so can not influence the welding of road assembly afterwards.Simultaneously, being provided with at interval of spring away from portion and contacting part, thus make spring stress evenly not yielding.
2, a plurality of of spring are locked on roller bearing away from portion, are difficult for deforming, and can prolong the working life of spring roller.
3, adjacent two identical away from the distance between adjacent two back electrodes of the distance between the portion and silicon chip, each is aimed at away between portion and each back electrode.
4, said number away from portion can be more than or equal to the bar number of the back electrode of said silicon chip, guarantee on the one hand every back electrode place of silicon chip can be corresponding one away from portion.
5, said away from portion along the length of said roller bearing less than the length of said contacting part along said roller bearing, the number of the spring ring that can guarantee contact with silicon chip can reach 22-29, thus the excellent conducting performance of assurance spring roller.
