Description

A kind of hook point of graphite frame

Technical field

The utility model relates to silicon solar cell manufacturing technology field, particularly a kind of hook point of graphite frame.

Background technology

At existing solar cell PECVD plating SI ₃N ₄In the operation of antireflective coating; Need to use the graphite frame that hook point (being hook, stop hook) has been installed as the instrument that carries silica-based solar cell, graphite frame 2 as shown in Figure 1, graphite frame 2 is a frame structure; Form by housing that is positioned at the edge 3 and housing 3 inner spacer bars 4; Spacer bar 4 comprises horizontal stripe 41 and vertical bar 42, and spacer bar 4 encloses the space 21 that the region separation of drawing together becomes several and the size of silicon solar cell to adapt with 3 of housings, and the hook point is installed on the framework 22 in this space 21 of formation.Cooperation between the specific form of hook point and it and the graphite frame can influence the performance quality of silicon chip film-coated outward appearance and battery sheet; And; If sheet and fragment phenomenon appear falling in the unreasonable silicon chip that will cause of hook point design on the graphite frame, also can produce the problem of inconvenient operation simultaneously.

At present; Hook point is unified structure not, and each producer can design according to actual needs and be fit to the hook point that the our factory produces, and the hook point generally comprises and is used for connection section that is connected with the graphite frame and the hook portion that is used for the support silicon chip; Hook portion has the tip and stretches in the space of graphite frame, point upward support silicon chip.Existing hook is put the following shortcoming of equal ubiquity: after (1) hook point is installed on the graphite frame; There is bigger gap between the framework of silicon chip edge and this hook point of installation; Will cause silicon chip to produce around the plating phenomenon during plated film, silicon chip back also can plate the phenomenon of silicon nitride film when plating is meant at plated film; (2) because the point upward support silicon chip of hook portion, silicon chip film-coated after, silicon chip surface can be stayed obvious marks by hook point support position, thereby influences the outward appearance of silicon chip.

The utility model content

The purpose of the utility model be to provide a kind of simple in structure, can improve around the plating phenomenon, dwindle hook point vestige greatly, can improve the silicon chip quality, the hook point of easy to operate graphite frame.

The purpose of the utility model realizes through following technical measures: a kind of hook point of graphite frame; Comprise coupler body; Said coupler body mainly is made up of connection section that is used for being connected with the graphite frame and the hook portion that is used for the support silicon chip; It is characterized in that said hook portion has is used for the upwards tip of support silicon chip, and this tip is stretched into the graphite frame and is used to place in the space of silicon chip.

The utility model simple in structure can effectively reduce the gap between silicon chip and the framework, and can control this gap minimum size is about 0.5mm; Obviously improve that silicon chip is occurred when plated film around the plating phenomenon; Make its area that contacts with silicon chip reduce owing to most advanced and sophisticated as support usefulness simultaneously, so after silicon chip film-coated; The most advanced and sophisticated vestige that stays on its surface is minimum, can not influence the outward appearance of silicon chip; In addition, the utility model rational in infrastructure makes and can reduce sheet and fragment phenomenon when silicon slice placed is placed on it, improves the silicon chip quality, and easy to operate.

As a kind of improvement of the utility model, said hook point mainly is made up of two coupler bodies side by side, and said hook portion is positioned at the end of said coupler body, and said hook portion is crooked round about, and the tip of hook portion is stretched into respectively in two adjacent spaces; Be provided with connection piece between the said coupler body, the two ends of said connection piece are connected with coupler body respectively.

The utility model also has following embodiment; Said connection section is " U " shape structure; Opening that should " U " shape structure upwards is fastened on the graphite frame as bayonet socket and constitutes on the framework in space, and the gap reduces between edge and the framework of the silicon chip on the hook portion so that be placed on; The scope in said gap is 0.5～1.5mm.Reduced the gap between silicon chip edge and the framework effectively, so improved obviously that silicon chip is occurred when plated film around the plating phenomenon.

As the utility model preferred embodiment, said hook point is the plate body shape, and said connection piece is near said hook portion setting.

The utility model can be done further improvement, and said hook point is for being made into integration.

The framework in the said formation of the utility model space is a square, and said hook point is provided with two respectively on the horizontal stripe of framework.

Improve further as the utility model, the termination of said connection section is provided with the lug that makes things convenient for the anchor clamps clamping.

Compared with prior art, the utlity model has following significant effect:

(1) the utility model can effectively reduce the gap between silicon chip and the framework, and can control this gap minimum size is about 0.5mm, obviously improve that silicon chip is occurred when plated film around the plating phenomenon.

(2) the utility model is because most advanced and sophisticated usefulness as support, therefore silicon chip film-coated after, the most advanced and sophisticated vestige that stays on its surface is minimum, can not influence the outward appearance of silicon chip.

(3) the utility model is rational in infrastructure, makes to reduce sheet and fragment phenomenon when silicon slice placed is placed on it, improves the silicon chip quality, and easy to operate.
