Background technology
Along with the demand of solar battery sheet constantly increases, the competition in battery sheet market is also more and more fierce, and each battery sheet production commercial city idea manages to improve the quality of battery sheet, increases competitiveness of product.
In battery sheet production technology, the size of the contact-making surface of silicon chip and graphite boat sheet carrier (hiding the area of silicon chip) has directly influenced the quality and the outward appearance of battery sheet, and for this reason, the masked area that as far as possible reduces contact point is the important topic that each manufacturer is concerned about.
Used in the past contact point (graphite particle is the contact point of a circle), the contact-making surface of silicon chip and graphite boat sheet carrier are circular, and contact area is bigger, has influenced the quality of battery sheet.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of contact area silicon chip little, that can improve the battery tablet quality fixedly to use reference column.
The technical scheme that provides according to the utility model, the fixing reference column of using of described silicon chip, comprise clamp, last joint pin, erection column, following joint pin and following clamp, described erection column is one section cylinder, be connected with joint pin at the upper surface of erection column, be connected with clamp at the upper surface of last joint pin, lower surface at erection column is connected with joint pin down, clamp under the lower surface of joint pin is connected with down, last joint pin is identical with the shape of following joint pin, the shape symmetry of last clamp and following clamp, between last clamp and erection column, form a draw-in groove, form another draw-in groove between erection column and following clamp, the described height of going up clamp or following clamp is less than or equal to the height of joint pin or following joint pin.
The described matrix of going up joint pin or following joint pin is the rectangular cylinder that vertically is provided with, two lateral walls at this rectangular cylinder is connected with the cylinder plate body, the width of cylinder plate body is identical with the width of described sidewall, and the axis of cylinder plate body overlaps with the line of bottom center with described rectangular cylinder end face center.
The described matrix of going up clamp or following clamp is the rectangular cylinder that vertically is provided with, two lateral walls at this rectangular cylinder is connected with the cylinder plate body, the width of cylinder plate body is identical with the width of described sidewall, and the axis of cylinder plate body overlaps with the line of bottom center with described rectangular cylinder end face center.
The diameter of described erection column is 6mm, and go up clamp or down the diameter of clamp equal the diameter of erection column, last clamp or down the diameter of clamp greater than the diameter of last joint pin or time joint pin.
The diameter of described erection column is 9mm, and goes up the diameter of the diameter of clamp or following clamp less than erection column, and the diameter of last clamp or following clamp is greater than the diameter of last joint pin or following joint pin.
The utility model in use, the contact-making surface of silicon chip and graphite boat sheet carrier is less, can improve the quality of battery sheet.
