Abstract
The utility model relates to a silicon chip bracket component with a quartz glass tube, which is applied in a silicon chip sintering furnace with no mesh belt. The silicon chip bracket component comprises the quartz glass tube, a metal sleeve, support legs and limit screws, the support legs are fixed on the metal sleeve, the metal sleeve is provided with threaded holes and is fixed on the quartz glass tube through the limit screws at the same interval, the support legs are made of steel wires, and ceramic coatings are coated on the surfaces of the steel wires. Since the quartz glass tube has high strength, high temperature resistance, a small expansion coefficient, high thermal shock resistance, high acid resistance, high chemical stability, a good electrical insulation performance, low heat absorption capacity and other advantages, the quartz glass tube is suitable for use as a silicon chip bracket. The support legs are made of steel wire and the outer surfaces of the support legs are coated with the ceramic coatings, so the support legs meet the requirements of the strength, high temperature resistance and wear resistance, and the metal ion pollution caused by metal contact can be reduced in sintering of silicon chips. The metal sleeve is provided with an opening and the threaded holes, and thus the metal sleeve can be conveniently fixed on the quartz glass tube.
Description
Technical field:
The utility model relates to a kind of no guipure silicon cell sintering furnace, relates in particular to chip transmission device in the no guipure silicon cell sintering furnace.
Background technology:
At present, the sintering furnace that manufacture of solar cells both domestic and external manufacturing firm mainly uses American-European enterprise and produced, this class sintering furnace structure all is a net belt type tunnel sintering furnace, sintering furnace vertically on be provided with preheating binder removal district successively, heating zone, sintering zone and cooling area, arrange the heating fluorescent tube of different densities in zones of different, control each regional temperature with this, the silicon chip that prints electrode transmits by guipure, pass through the different furnace temperature district of sintering furnace successively, finish the preheating binder removal, heat up, the electrode sintering process of sintering and cooling, though this net belt type tunnel sintering technology comparative maturity, but vertical floor space of whole sintering furnace is big, need the very long body of heater of design could guarantee the preheating binder removal of silicon chip in the tunnel transmission course, heat up, sintering, temperature-fall period, because the technological temperature in high temperature sintering district need be between 850-950 ℃, therefore need the length of tunnel of design 2-3 rice just can reach so high temperature, this makes the bulky of net belt type sintering furnace.Can't satisfy the sintering process requirement if dwindle then.In addition, high temperature resistant guipure is in the process of running, need be inside and outside body of heater cycle operation, guipure partly follows silicon chip to accept the process that heats up and lower the temperature, therefore, in operation process, guipure can carry out a large amount of heats in stove, and this part heat will be all as loss, not only caused the waste of big energy, and the operating ambient temperature that raise, for this reason, the applicant has developed a kind of no guipure silicon cell sintering furnace, it can overcome the deficiency that existing net belt type tunnel sintering furnace exists well, and this occupation area of equipment is little, thermal efficiency height, power consumption is few, and energy-saving effect is remarkable.
Described no guipure silicon cell sintering furnace, comprise loading bay 1, tunnel type sinter box 2, discharge pedestal 3, silicon chip conveying device 4 and furnace body frame 5, as shown in Figure 1, silicon chip conveying device 4 is arranged between loading bay 1 and the discharge pedestal 3, and be arranged in tunnel type sinter box 2, silicon chip conveying device 4 comprises analog bracket 41 and movable support bracket 42, the two ends of analog bracket 41 are separately fixed on the fixed mount in loading bay 1 and the discharge pedestal 3, the two ends of movable support bracket 42 are separately fixed on the sliding panel that is driven by multiple elevating mechanism and reciprocal translation mechanism, movable support bracket 42 is under the double action of reciprocal elevating mechanism and reciprocal translation mechanism, make movable support bracket 42 periodically finish rising, reach, descend and backward movement, thereby the silicon chip that will be placed on the analog bracket 41 is progressively moved forward.In this no guipure silicon cell sintering furnace, analog bracket 41 still is that movable support bracket 42 all must be stablized for a long time under 850-950 ℃ hot environment indeformable, and adopting which type of silicon chip carriage member is one of key technology of no guipure silicon cell sintering furnace.
The utility model content:
The purpose of this utility model is to provide a kind of quartz glass tube silicon chip carriage member for no guipure silicon cell sintering furnace.
The technical scheme that the utility model adopted is:
Described quartz glass tube silicon chip carriage member, it is characterized in that: comprise quartz glass tube, metallic sheath, stand-off and stop screw, stand-off is fixed on the metallic sheath, is provided with screwed hole on metallic sheath, and metallic sheath is fixed on the quartz glass tube equally spacedly by stop screw.
Further, on quartz glass tube, in axial direction have spacing hole equidistantly; On metallic sheath, also be provided with opening.
Further, described stand-off is made by steel wire, scribbles ceramic coating in Steel Wire Surface.
Since quartz glass tube have the intensity height, high temperature resistant, the coefficient of expansion is low, resistance to heat shocks, acid resistance, chemical stability, advantage that electrical insulation capability is good, it is well suited for the lever as the silicon chip carriage, the tubular structure caloric receptivity is few, stand-off is made with steel wire, and be provided with ceramic coating at its outer surface, so both satisfied the intensity that stand-off should possess, high temperature resistant, wear-resistant requirement, reduced the metal ion pollution that silicon chip causes owing to silicon chip and Metal Contact again in sintering process.On metallic sheath, offer opening, be convenient to the suit of metallic sheath at quartz glass tube; Offering screwed hole on metallic sheath, offer locating hole on quartz glass tube, all is for the ease of with stop screw metallic sheath being fixed on the quartz glass tube.
