Abstract
The utility model discloses the furnace zone of a chain type sintering furnace, which comprises a conveyor belt (1) and a battery sheet support (2) arranged on the conveyor belt (1). The battery sheet support (2) is rod-shaped and is obliquely fixed on the conveyor belt (1). A platform (3) parallel to the plane of the conveyor belt (1) is arranged on the battery sheet support (2) and is used for fixing the etching edge of a battery sheet. According to the utility model, due to the adoption of the platform arranged on the conveyor belt, the etching edge of a battery sheet just leans on the platform and an aluminum back-surface field is in no contact with the conveyor belt. Therefore, the generation of belt stamps and aluminum stabs due to the mutual contact of the aluminum back-surface field and the conveyor belt is avoided and the appearance of a battery sheet is ensured. The conversion efficiency of battery sheets is also improved.
Description
Technical field
The utility model relates to a kind of sintering furnace furnace zone, relate in particular to a kind of after the silicon solar cell serigraphy furnace zone of chain-type sintering furnace.
Background technology
In the manufacture craft process of silicon solar cell, the two-face printing positive and negative electrode of the silicon chip of requirement after forming pn knot and plated film and back of the body field form good Ohmic contact, and this is to realize through the sintering after the serigraphy.
Serigraphy is attached to printing on the silk screen the masterplate that has image or pattern.When below stock is placed directly in the silk screen that has masterplate, screen printing ink or coating pass the mesh in the middle of the silk screen under the extruding of scraper, be printed onto on the stock.Masterplate on the silk screen is sealed a part of silk screen aperture and is made pigment can not pass silk screen, and has only image section to pass, and therefore on stock, has only the image position that trace is arranged.In other words, serigraphy is actually and utilizes ink penetration to cross that forme prints.
Because the plasticity of slurry, the slurry of printing just are bonded at the purpose that collected current can not be played in the surface of battery.The purpose of sintering makes slurry and silicon chip form good Ohmic contact exactly.Sintering furnace is divided into presintering, sintering, cooling cooling three phases.Presintering stage purpose is to make the polymer binder in the slurry decompose, burn, and this phase temperature slowly rises; Sintering is accomplished various physical-chemical reactions in the sintering body of heater in the stage, form the resistive film structure, makes it really have resistance characteristic, and this phase temperature reaches peak value; The cooling cooling stage, the frit hardening by cooling is also solidified, and the resistive film structure is adhered on the battery sheet regularly.
In the middle of production process; When using the battery sheet that existing sintering furnace furnace zone sintering just printed; One side is because the battery sheet contacts with the point of conveyer belt, and it is inhomogeneous that aluminium back of the body field is heated, and there is hickie aluminium back of the body field with battery sheet position contacting; Even have aluminium bag, aluminium thorn to form, influence the outward appearance and the conversion efficiency of battery sheet.On the other hand; The battery sheet from furnace zone that sintering furnace is taken in the transmission of printing machine to because the relation of inertia, very possible run-off the straight of battery sheet or distortion, like this during the pulldown of 4# machine video camera warning or manipulator misoperation influence battery sheet output easily; Increase fragment rate, increase production cost.
The utility model content
The utility model purpose: the purpose of the utility model is the deficiency to prior art, provides a kind of result of use good serigraphy sintering furnace furnace zone.
Technical scheme: the furnace zone of the described chain-type sintering furnace of the utility model; Comprise conveyer belt, be arranged on the battery plate rack on the said conveyer belt, said battery plate rack is shaft-like; Tilt to be fixed on the said conveyer belt; Said battery plate rack is provided with the etching limit that the platform that is parallel to said conveyer belt plane is used for fixing the battery sheet, and the etching limit of battery sheet is just in time ridden on the platform, and aluminium back of the body field does not have any contact with conveyer belt.
In order to satisfy the needs of different specification of battery, the said platform of the utility model comprises first platform and second platform, is separately positioned on the differing heights place of said battery plate rack, is used for fixing the etching limit of 125mm*125mm and 156mm*156mm battery sheet respectively.
Preferably, the angle of inclination of said battery plate rack and said conveyer belt is 15 °, and the height on the said driving-belt of said first platform distance plane is 6.6mm; Said second platform is 10mm apart from the height on driving-belt plane; Just in time on platform, aluminium back of the body field does not have any contact with platform on the etching limit of two kinds of battery sheets.
The said conveyer belt of the utility model is woven into by plain net and oblique net, and said battery plate rack is welded on the plain net of said conveyer belt or tiltedly online.
The battery plate rack in the aspect ratio tradition furnace zone of the said battery plate rack of the utility model is high, and the mesh of chain conveyor is bigger than the mesh in traditional furnace zone, and battery plate rack gap ratio traditional burner belt supporting frame spacing is big.
The utility model compared with prior art; Its beneficial effect is: 1, the utility model is through being arranged on the platform on the conveyer belt; The etching limit of battery sheet is just in time ridden on the platform, and aluminium back of the body field does not have any contact with conveyer belt, has avoided because guipure seal that contact causes and aluminium thorn; Guarantee the outward appearance of battery sheet, improved the conversion efficiency of battery sheet.2, the utility model sintering furnace furnace zone plain net and the tiltedly increase of the gap between the net are heated the battery sheet and are more evenly further reduced the conversion efficiency that Ohmic resistance improves the battery sheet.3, there has been the protection of platform in the utility model sintering furnace furnace zone; Make the thermal current in the sintering furnace stove drop to minimum with the influence of protecting gas to the battery sheet; Guarantee that the battery sheet can not move in the process of sintering, reduced the number of times of warning of 4# chance error or misoperation, improved the output of battery sheet.4, metal belt has been reduced to the carrying of temperature in the sintering furnace stove in the utility model sintering furnace furnace zone, makes in the stove temperature more stable, further improves the production capacity of battery sheet.
