Description
Technical field
The utility model relates to a kind of solar battery sheet production equipment, is specially the graphite boat transfer car(buggy) in the production of a kind of solar battery sheet.
Background technology
The technological process of production of solar battery sheet is divided into silicon chip to detect, surface wool manufacturing and pickling, diffusion, dephosphorization silex glass, plasma etching and pickling, coated with antireflection film, silk screen printing, Fast Sintering etc.
The key step of plasma etching is,
Due in diffusion process, spread back-to-back even if adopt, all surface of silicon chip comprises edge and all inevitably will spread phosphorus.Light induced electron collected by the front of PN junction can have the region of phosphorus to flow to the back side of PN junction along edge-diffusion, and causes short circuit.Therefore, must etch the doped silicon of solar cell periphery, to remove the PN junction of battery edge.Usual employing plasma etching technology completes this technique.Plasma etching is in a low voltage state, and the parent molecule of reacting gas CF4, under the exciting of radio-frequency power, produces and ionizes and form plasma.Plasma is made up of charged electronics and ion, and the gas in reaction cavity, under the shock of electronics, except being transformed into ion, can also absorbing energy and form a large amount of active groups.Active reactive group is due to diffusion or arrive SiO2 surface under electric field action, there with the material surface generation chemical reaction that is etched, and forms volatile reaction product and departs from and to be etched material surface, extracted out cavity by vacuum system.
Be placed in graphite boat through the silicon chip after over etching, need PECVD coating film treatment, plasma enhanced CVD (PECVD) the equipment operation principle of medium is, under the vacuum pressures, be added in the rf electric field on battery lead plate, make reative cell gas generation glow discharge, produce a large amount of electronics in glow discharge region.These electronics obtain sufficient energy under the effect of electric field, and itself temperature is very high, and it and gas molecule collide, and gas molecule is activated.They are adsorbed on substrate, and concurrent biochemical reaction generates deielectric-coating, and accessory substance, from desorb substrate, is taken away by vacuum pump with primary air.
This intermediate demand uses a kind of special purpose device graphite boat, and graphite boat itself is very accurate, and temperature is higher, people can not directly contact, and therefore needs a transloading equipment, after processing, graphite boat must use this equipment to deliver to cooling room, after having cooled, also need to use this equipment to deliver to workbench, then get sheet.
Summary of the invention
The utility model, in order to solve the transshipment problem of graphite boat special in solar silicon wafers processing, provides the graphite boat transfer car(buggy) in the production of a kind of solar battery sheet.
The technical solution of the utility model is, graphite boat transfer car(buggy) in a kind of solar battery sheet production, structure comprises movable stand, in the middle part of movable stand, be provided with platform, is provided with two supporting plates in the middle part of platform, centering block is equipped with by axle in the middle of supporting plate, centering block connects handle, on front side of centering block, is provided with lockset, in the middle part of centering block, be provided with rotating shaft, rotating shaft is provided with turntable, and turntable 20 is provided with the mounting table of graphite boat;
Be body cradle in the middle part of described lockset, wear bull stick in body cradle, bull stick is provided with driving lever, bull stick two ends are provided with locknut, are provided with snap close in body cradle both sides, are between degating region between described snap close and locknut, described turntable is provided with locking bar, and locking bar is positioned between degating region;
Described supporting plate is provided with prelocalization bar, rear backstay, and prelocalization bar is provided with front support rod 7, and rear backstay is provided with back stay.
In using, graphite boat can directly be placed on mounting table, graphite boat can be carried in workshop, go to get sheet or inserted sheet operation, only need to press down handle, centering block can be made to rotate counterclockwise, mounting table is driven to form a heeling condition, facilitate operated by personnel, when graphite boat needs to rotate time, press down driving lever, bull stick is made to drive locknut to rotate, locking bar then departs between degating region, after whole turntable rotates 180 °, the locking bar other end turns to again the opposite side of lockset, reenter in the degating region of locknut and snap close formation, turntable is fixed, staff starts operation.
Graphite boat rotating device described in the utility model, structure is simple, reasonable in design, can realize the conveying object of graphite boat, graphite boat can also be made simultaneously to have front and back and rotate, and the function horizontally rotated.What facilitate solar battery sheet on graphite boat gets sheet, inserted sheet work, the work such as sorting.Improve efficiency and product quality.
