Description

A kind of telescopic battery sheet suction means

Technical field:

The utility model relates to the pecvd process of manufacture of solar cells, relates in particular to the suction sheet device of using in the pecvd process.

Background technology:

PECVD is the abbreviation of solar battery sheet plasma chemistry deposition plating technology; In the production process of solar cell; To silicon chip film-coated be the gordian technique that improves the solar cell assimilated efficiency, according to the opto-electronic conversion electricity generating principle of silicon chip, irradiate light can produce reflection to silicon chip; The optical loss of silicon chip can make the output of solar cell be lower than ideal value; Silicon chip film-coated technology is to improve the mature technology of solar cell assimilated efficiency, in solar cell industry production, is used widely, can form one deck antireflective coating at silicon chip surface through PECVD.

The electroless plating plated film principle of solar cell filming equipment is: many vitreosil pipes are housed in the enclosed vacuum deposition source; In every vitreosil pipe, be placed with a copper pipe, in deposition source, feed silane and ammonia, make the copper pipe in the vitreosil pipe launch microwave through automatically controlled part again; Under hot conditions; Silane in the deposition source, ammonia and silicon chip react the generation silicon nitride, and silicon nitride can slowly be deposited on the battery sheet surface, thereby realizes silicon chip film-coated.After PECVD accomplished, because the temperature in the diffusion furnace is higher, and the degree of depth was bigger in the stove, and battery sheet temperature is also higher; If the battery sheet that breaks wherein occurs, must use vacuum to inhale the sheet instrument in the time of perhaps need certain sheet battery sheet being taken out, it is the vacuum record sucking apparatus that existing vacuum is inhaled the sheet instrument; The vacuum record sucking apparatus is made up of vacuum slot, vacuum hose, vacuum switch, and vacuum hose one end and vacuum slot are tightly connected, and the other end and vacuum switch are tightly connected; Open vacuum switch when drawing the battery sheet, because negative pressure of vacuum, vacuum slot can hold the battery sheet; Close vacuum switch in the time of need putting down, this moment, negative pressure was broken off, and the battery sheet falls.Because vaccum suction pipe is made by the plastelast flexible pipe, can't support and draw distance battery sheet far away.This vacuum is inhaled the sheet device and is used very inconveniently, not only be difficult for drawing battery sheet at a distance, and vacuum hose is exposed in the diffusion furnace, and use under the comparatively high temps environment, its work-ing life is not long.Therefore be necessary to design and a kind ofly can overcome the insufficient vacuum of prior art and inhale the sheet device.

The utility model content:

In order in PECVD, to carry out suction operation to the battery sheet of different positions, the utility model provides a kind of telescopic battery sheet suction means, and it is not only convenient but also reliable to draw the battery sheet with it.

The technical scheme that the utility model adopted is:

A kind of telescopic battery sheet suction means comprises suction nozzle, expansion link, vacuum hose and vacuum switch, wherein; Expansion link comprises hand-held loop bar, transition loop bar and inner core sleeve pipe, is provided with the connecting hole that connects suction nozzle at inner core telescopic right-hand member, is provided with the limit shaft rank at inner core telescopic left end; Suction nozzle is fixedly mounted in the inner core telescopic connecting hole, and vacuum hose one end is sleeved on the inlet pipe of suction nozzle hermetically, and the other end links to each other with vacuum source through vacuum switch; Right-hand member at the transition loop bar is provided with the spacing shaft shoulder in the transition; The internal diameter of the shaft shoulder is corresponding with inner core telescopic external diameter in the said transition, is provided with the spacing shaft shoulder outside the transition at the left end of transition loop bar, and the said transition external diameter of the spacing shaft shoulder outward is corresponding with the internal diameter of hand-held loop bar; Right-hand member at hand-held loop bar is provided with the spacing shaft shoulder in the overcoat; The internal diameter of the spacing shaft shoulder is corresponding with the external diameter of transition loop bar in the said overcoat, and the transition loop bar is sleeved in the hand-held loop bar, and the inner core cover pipe box is contained in the transition loop bar.

Further, be provided with screw thread in the connecting hole inboard, be installed with a nut in inner core sleeve pipe one end in that suction nozzle is to be installed, the screw thread of this nut is in the outside, and it forms spiral the fixed connection with suction nozzle with the inner core cover pipe.

Further, in inner core telescopic left end endoporus, be provided with the fixedly flexible fastening circle of vacuum hose.

Because the utility model has adopted expansion link; And vacuum hose is sleeved in the expansion pipe; Vacuum slot is fixedly mounted on inner core telescopic front end; Vacuum hose is enclosed within hand-held loop bar, transition loop bar and the inner core telescopic endoporus, prevents that vacuum hose is directly exposed in the higher diffusion furnace of temperature, influences its work-ing life.The expansion link structure makes vacuum slot be competent to advance and retreat-at will, and the operator is as long as regulate the length of expansion link, and the operator need not walk about and just can draw the battery sheet easily, not only easily but also make things convenient for.
