Abstract
The utility model provides a roller for conveying silicon slices in a silicon etching process, which comprises roller bodies, clamp rings and anti-skidding rings, wherein six clamp rings are evenly arranged on each roller body, the distance between two adjacent clamp rings is larger than the size of the silicon slices, and at least two anti-skidding rings are further evenly arranged on the roller body between every two adjacent clamp rings. Through improvement of the roller, accidents of slice clamping, stacking and the like caused by orbit displacement of the silicon slices can be completely avoided, slice breaking rate is greatly reduced, rolled yield is remarkably improved, shut down time is reduced, and continuity and stability of production are ensured.
Description
Technical field
The utility model relates to a kind of roller that in silicon chip making herbs into wool process, transmits silicon chip.
Background technology
In the production process of crystal-silicon solar cell, the making herbs into wool operation adopts the wet etching technology when removing silicon chip surface damage layer, and preparation one deck matte is used for antireflective.Realize the general wet etching machine that adopts of this technology, this equipment is the chain type continuous mode of production, is divided into 5 tracks; Be made up of a plurality of functional modules, all by roller transmission silicon chip, the Input district gets into first module of board for silicon chip; Foreign vendor can be automatic transmission system equipment of Input district configuration, and the orbital position that silicon chip gets into behind the Input district can not squint basically, so the roller in the Input district does not design silicon chip track correcting device; And domestic manufacturers because taking cost into account, and Input district majority is the artificial sheet of throwing, and adds other factors; Like the slight vibrations of equipment itself, have a strong impact on the track accuracy rate of silicon chip, can produce orbit displacement; The silicon chip that part interorbital deviation is bigger can bump against with the silicon chip of other tracks behind access arrangement or be overlapping; Cause lamination or card accident, produce a large amount of fragments and nonconformity sheet, and have a strong impact on the continuity of production.
The utility model content
The purpose of the utility model is to provide a kind of roller that in silicon chip making herbs into wool process, transmits silicon chip, and it can effectively revise the shift phenomenon that chip transmission produces, the accident of avoiding lamination, card and hitting sheet.
The utility model provides a kind of roller that in silicon chip making herbs into wool process, transmits silicon chip, and it comprises roller, snap ring, antislip ring; Wherein, evenly be provided with 6 snap rings on each roller, the distance between two adjacent snap rings is greater than the size of silicon chip; On the roller between two whenever adjacent snap rings, also evenly be provided with at least 2 antislip rings.
Wherein, the annulus width sum of said silicon wafer thickness and antislip ring is less than or equal to the annulus width of snap ring.
Further, on the roller between two whenever adjacent snap rings, also evenly be provided with at least 4 antislip rings.
The utility model can be avoided significantly improving first-pass yield because accidents such as the card that the silicon chip orbit displacement causes, lamination significantly reduce fragment rate through the improvement of pair roller fully, reduces the Down machine time, guarantees the continuity and the stability of producing.
Description of drawings
The structural representation of Fig. 1 the utility model
Wherein, 1-roller, 2-snap ring, 3-antislip ring.
The specific embodiment
As shown in Figure 1, the utility model is a kind of roller that in silicon chip making herbs into wool process, transmits silicon chip, and it comprises roller 1, snap ring 2, antislip ring 3; Wherein, evenly be provided with 6 snap rings 2 on each roller 1, the distance between two adjacent snap rings 2 is greater than the size of silicon chip; On the roller 1 between two whenever adjacent snap rings 2, also evenly be provided with at least 2 antislip rings 2.Wherein, the annulus width sum of said silicon wafer thickness and antislip ring 3 is less than or equal to the annulus width of snap ring 2.On the roller 1 between two whenever adjacent snap rings 2, also evenly be provided with at least 4 antislip rings 3.
Distance between two adjacent snap rings can guarantee that greater than the size of silicon chip silicon chip can not depart from transporting rail; Simultaneously, the antislip ring of setting can strengthen the friction dynamics to silicon chip, further prevents silicon chip offset rail in transmission course.Wherein, antislip ring and snap ring all adopt the material that is difficult for silicon chip is caused damage.Simultaneously, the present invention evenly is provided with 6 snap rings, and roller is divided into 5 sections, and each section can be corresponding with 5 tracks of board.
The utility model can be avoided significantly improving first-pass yield because accidents such as the card that the silicon chip orbit displacement causes, lamination significantly reduce fragment rate through the improvement of pair roller fully, reduces the Down machine time, guarantees the continuity and the stability of producing.
