Description

Oblique loading end carbon fiber support plate

Technical field

This utility model belongs to the process equipment technical field of photovoltaic products, is related to board-like PECVD plated films, PERC batteries The structure of the support plate in the solar battery sheet coating process such as back of the body passivation and plated film is improved, and in particular to a kind of oblique loading end carbon is fine Dimension support plate.

Background technology

In the silicon wafer fabrication process of solaode, silicon chip is loaded by carbon fiber support plate, enters back into board-like PECVD lifes Producing line carries out plated film, it is seen that support plate loading is one necessary operation that silicon chip becomes in the production process of cell piece.Existing support plate Structure as shown in figure 1, the part that support plate holds silicon chip during its work is step surface, facade is with the angle of plane on step surface 90, and in process of production, what the loading end on silicon chip and support plate was always contacted, work is produced through high temperature and accordingly After skill, in contact surface position, the film layer that support plate can be plated to silicon chip can produce certain impact, such as edge effect.

Existing silicon chip support plate structure is improved, its impact to silicon chip film-coated marginal portion is preferably minimized, just into For this area technical problem urgently to be resolved hurrily.

The content of the invention

Goal of the invention：In order to overcome the deficiencies in the prior art, it is fine that this utility model provides a kind of oblique loading end carbon Dimension support plate.

Technical scheme：To solve above-mentioned technical problem, the oblique loading end carbon fiber support plate that this utility model is provided, in support plate On offer groove for loading silicon chip, there is the loading end for holding silicon chip at the edge of groove, the loading end is to groove Tilted inclined entrusting surface, the inclined entrusting surface is arranged at least two sides of carried silicon chip.

Specifically, the inclined entrusting surface is arranged in the surrounding of silicon chip, so as to more stably lift to the surrounding of silicon chip.

Specifically, the inclination angle of the inclined entrusting surface is 10-50, and using inclined-plane the edge of silicon chip is lifted, and is ensureing minimum connecing Contacting surface realizes optimal supporting effect while product.

Specifically, the height of the inclined entrusting surface is 10 ~ 20 times of silicon wafer thickness.

Specifically, there is transition face between the top of the inclined entrusting surface and support plate upper table mask.

Specifically, the transition face is step surface, and the deep gouge that step surface is formed can avoid silicon chip displacement.

Specifically, the inclined entrusting surface is symmetrically, symmetrical with the center line for being lifted silicon chip, the support that inclined-plane is applied to silicon chip Lifting force is decomposed into vertical component and horizontal component, vertical component and silicon chip gravitational equilibrium, the horizontal component size of two symmetrical slopes It is equal, it is in opposite direction, so as to cancel out each other, it is ensured that the stress of silicon chip is in poised state.

Beneficial effect：The contact surface of support plate and silicon chip is modified to angle C by this utility model from existing 90 platform terrace An inclined entrusting surface, and then by silicon chip and support plate contact by face contact make linear contact lay into, greatly reduce contact surface, it is to avoid plated film give birth to Impact during product, it is to avoid film layer adverse effect, improves the plating membrane efficiency of cell piece.

Except this utility model recited above solve technical problem, constitute technical scheme technical characteristic and by this Outside the advantage that the technical characteristic of a little technical schemes is brought, oblique loading end carbon fiber support plate of the present utility model can solve its The advantage that the other technical characteristics and these technical characteristics included in his technical problem, technical scheme are brought, will combine accompanying drawing It is described in more detail.

Specific embodiment

Embodiment 1：

The inclined-plane support plate 3 of the present embodiment is as shown in Fig. 2 with the inclined entrusting surface touched with the side edge of silicon chip 1, the side of silicon chip 1 Edge forms linear contact lay with inclined entrusting surface, greatly reduces the contact area of silicon chip and support plate, support plate is reduced to greatest extent plated film is given birth to The impact that product process is produced.Step-like transition face is formed between the top of inclined entrusting surface and support plate upper table mask, is easy to support plate to add Work and upper piece when positioning.

As shown in figure 3, there is the groove of matrix arrangement on oblique loading end carbon fiber support plate, for carrying multi-disc silicon chip simultaneously Carry out plated film.As shown in Figure 4 and Figure 5, the face of trough rim contact silicon chip edge is inclined-plane, and inclination angle C takes 10-50, is ensureing minimum Contact area while, inclined-plane is lifted stability and can be optimal to silicon chip edge.

Embodiment of the present utility model is described in detail above in association with accompanying drawing, but this utility model is not limited to institute The embodiment of description.For one of ordinary skill in the art, in principle of the present utility model and the scope of technological thought It is interior, various changes, modification, replacement and deformation are carried out to these embodiments and is still fallen within protection domain of the present utility model.
