Abstract

A bilateral shifting mechanism of silicon wafer movable brackets in a mesh-belt free high-efficiency sintering furnace comprises a horizontal push rod, a lever, a rotating pin, a supporting seat, a slider and a vertical guide rail. The vertical guide rail is vertically fixed on sliding plates, the slider is sleeved on the vertical guide rail, the upper end of the lever is hinged with the slider, the lower end of the lever is hinged with the horizontal push rod, the middle of the lever is mounted on the supporting seat through the rotating pin, and the supporting seat is mounted on fixed base plates. As the movable brackets are fixed on the sliding plates of a feed table and a discharge table, when the horizontal push rod shifts leftwards and rightwards, the lever is capable of rotating around the rotating pin; since the lower end of the lever is hinged with the horizontal push rod, the upper end of the lever is hinged with the slider, the slider is sleeved on the vertical guide rail, the vertical guide rail is fixed on the sliding plates, and the sliding plates are sleeved on a slide rail, the sliding plates are capable of shifting bilaterally, and processing requirements are met.

Background technology:

In the solar cell piece production technology, sintering is to make the crystalline silicon substrate really have a vital step of photoelectric converting function.Therefore, the performance quality of agglomerating plant directly affects the quality of battery sheet.

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 the efficient sintering furnace of a kind of no guipure, it can overcome the deficiencies in the prior art well, and occupation area of equipment is little, thermal efficiency height, power consumption is few, and energy-saving effect is remarkable.

The efficient sintering furnace of described no guipure, 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, vertically be provided with preheating binder removal district 21, heating zone 22, sintering zone 23 and 24 4 zones of cooling area successively along tunnel type sinter box 2, between preheating binder removal district 21, heating zone 22, sintering zone 23 and cooling area 24, be equipped with thermal insulation board 25 and air-flow partition door 8, in preheating binder removal district 21, heating zone 22 and sintering zone 23, be provided with heating fluorescent tube 26, as shown in Figure 2; Silicon chip conveying device 4 is arranged between loading bay 1 and the discharge pedestal 3, it comprises analog bracket 41 and movable support bracket 42, the two ends of analog bracket 41 are separately fixed on the fixed mount 12 and 32 in loading bay 1 and the discharge pedestal 3, the two ends of movable support bracket 42 are separately fixed on the sliding panel 17,37 in loading bay 1 and the discharge pedestal 3, and analog bracket 41 is between two adjacent movable support brackets 42; Loading bay 1 is identical with the structure of discharge pedestal 3, all comprise fixed base plate 11,31, fixed mount 12,32, guide post 13,33, fairlead 14,34, portable plate 15,35, slide rail 16,36 and sliding panel 17,37, portable plate 15,35 with fixed base plate 11, pass through guide post 13 between 31,33 with fairlead 14,34 suit fit structure is connected, slide rail 16,36 are fixed on portable plate 15, on 35, sliding panel 17,37 are sleeved on slide rail 16, on 36, at fixed base plate 11,31 and portable plate 15, be provided with reciprocal elevating mechanism 6 between 35, fixed base plate 11,31 are installed on the furnace body frame 5, at fixed base plate 11,31 with sliding panel 17, be provided with reciprocal translation mechanism between 37, as Fig. 3, Fig. 4, shown in Figure 5, back and forth elevating mechanism 6 drives portable plate 15,35 with respect to fixed base plate 11,31 periodically finish rising and down maneuver, back and forth translation mechanism drives sliding panel 17,37 with respect to portable plate 15,35 periodically finish the mobile work of reach and back, as shown in Figure 3.Hence one can see that, and back and forth elevating mechanism 6 and reciprocal translation mechanism are the core driving mechanisms in the efficient sintering furnace of no guipure.

The utility model content:

The purpose of this utility model is the left and right sides translation mechanism that a kind of silicon chip movable support bracket is provided for the efficient sintering furnace of no guipure.

The technical scheme that the utility model adopted is:

The left and right sides translation mechanism of described silicon chip movable support bracket, comprise horizontal push, lever, ship and resell on another market, supporting base, slide block and upright guide rail, upright guide rail is fixed on the sliding panel vertically, slide block set is contained on the upright guide rail, the upper end and the slide block of lever are hinged, the lower end and the horizontal push of lever are hinged, and the middle part of lever is installed on the supporting base by shipping and reselling on another market, and supporting base is installed on the fixed base plate.

Because movable support bracket is fixed on the sliding panel of loading bay and discharge pedestal, when the translation of the horizontal push left and right sides is moving, the lever pin that will rotate rotates, because the lower end and the horizontal push of lever are hinged, the upper end and the slide block of lever are hinged, and slide block set is contained on the upright guide rail, because upright guide rail is fixed on the sliding panel, sliding panel is sleeved on the slide rail, thereby forces sliding panel to realize left and right sides translational motion, satisfies technological requirement.
