Abstract
The utility model discloses a heterojunction battery piece oven conveyor which comprises a preceding stage conveyor belt and an oven conveyor belt. Battery piece holders are arranged on the surface of the oven conveyor belt. The preceding stage conveyor belt comprises a first rotary shaft, a second rotary shaft and a belt. The belt is arranged on the two ends of the first rotary shaft and the second rotary shaft. The first rotary shaft is supported by a first support and the second rotary shaft is supported by a second support. A perpendicular cylinder is arranged on the lower end of the second support. The heterojunction battery piece oven conveyor enables a heterojunction battery piece to slide into each battery piece holder steadily and completely so that when the heterojunction battery pieces are capable of being placed in the battery piece holders and are not prone to drop and slip out, and therefore the battery pieces are protected from dropping and being broken, fragment rate is reduced and manufacturing cost is reduced.
Description
Technical field
The utility model relates to a kind of conveyer of carrying cell piece, particularly relates to a kind of conveyer of the hetero-junction solar cell sheet being sent into baking oven.
Background technology
At present, the high problem of solar power hetero-junction solar cell industry faces fragment rate.The production process of hetero-junction solar cell sheet comprises screen printing and the follow-up stoving process of cell substrate, and is very easy to occur the cell piece fragmentation in the process of being carried cell piece by silk-screen printing technique toward baking operation.This is because the conveying of cell piece is to carry by multiple tracks belt conveyor one-level one-level, until deliver to the belt conveyor of baking oven.In order in the cell piece drying course, to leave as far as possible few crawler belt seal, the belt conveyor great majority adopt the belt conveyor with the cell piece retainer in the existing heterojunction solar battery baking oven, the retainer of cell piece is made by metal frame, it is vertically set on the belt conveyor surface, after the prime belt conveyor was sent cell piece into the cell piece retainer, cell piece was just sent into baking oven by driving band and is dried along with the cell piece retainer.In the prior art, as shown in Figure 1, prime belt conveyor 1 is arranged on before the conveyor belt of baking oven 2, prime belt conveyor 1 a little less than conveyor belt of baking oven 2 so that prime belt conveyor 1 surface elevation flush with conveyor belt of baking oven 2 axle center height.After cell piece 3 is sent to prime belt conveyor 1, be delivered to again in the cell piece retainer 4 that is horizontal on the conveyor belt of baking oven 2 by prime belt conveyor 1, because the friction drag that exists between cell piece retainer 4 and the cell piece 3 is so that cell piece 3 can't enter cell piece retainer 4 fully.And in order to reduce as far as possible cell piece crawler belt seal, therefore the cell piece retainer degree of depth designs more shallowly usually, if cell piece can't enter the cell piece retainer fully, in the process of the motion of conveyor belt of baking oven subsequently cell piece as easy as rolling off a log from the cell piece retainer, skid off to drop cause a large amount of fragments.The rising of fragment rate, the productive costs of cell piece will improve, so how to reduce or the fragment rate of eliminating cell piece is a problem that must solve at present.
The utility model content
The purpose of this utility model provides a kind of hetero-junction solar cell sheet baking oven conveyer, and the cell piece that reduces in the conveyor belt of baking oven course of conveying so that cell piece can enter the cell piece retainer easily fully drops, and reduces fragment rate.
The technical solution of the utility model is such: a kind of hetero-junction solar cell sheet baking oven conveyer, comprise prime belt conveyor and conveyor belt of baking oven, described conveyor belt of baking oven surface is provided with the cell piece retainer, it is characterized in that: described prime belt conveyor comprises the first rotating shaft, the second rotating shaft and belt, described belt is arranged on the two ends of the first rotating shaft and the second rotating shaft, described the first rotating shaft is by the first stent support, and described the second rotating shaft is by the second stent support, and described the second support lower end is provided with vertical cylinder.
Device provided by the utility model, after hetero-junction solar cell sheet after carrying out screen printing is sent to the prime belt conveyor by belt conveyor, vertical cylinder under the second support is movable, reduce the height of the second support, so that originally angled to the second axes of rotation skew for the prime belt conveyor that is horizontal.The hetero-junction solar cell sheet is changed into tilting to transmit by original horizontal transmission when the prime belt conveyor is delivered to conveyor belt of baking oven like this, hetero-junction solar cell sheet hetero-junction solar cell sheet self gravitation in the cell piece retainer can overcome certain resistance along the component of cell piece retainer direction, so that the hetero-junction solar cell sheet is more prone to such an extent that to slip into the cell piece retainer inner.
Cause the fragmentation of cell piece in order to prevent the hetero-junction solar cell sheet from clashing into cell piece retainer bottom when slipping into the cell piece retainer, described cell piece retainer bottom is provided with elastic buffering pad.
The advantage of technical scheme provided by the utility model is, the hetero-junction solar cell sheet can slip into to stability and safety the cell piece retainer, make it enter retainer fully, and then guarantee that the hetero-junction solar cell sheet is when conveyor belt of baking oven operates, can be firm be in the cell piece retainer and be not easy to come off and skid off, cause the fragmentation of dropping of cell piece, reduced fragment rate, reduce production costs.
Description of drawings
Fig. 1 is hetero-junction solar cell sheet baking oven conveyer structural representation in the prior art;
Fig. 2 is the utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but not as to restriction of the present utility model.
See also Fig. 2, hetero-junction solar cell sheet baking oven conveyer, comprise prime belt conveyor 1 and conveyor belt of baking oven 2, conveyor belt of baking oven 2 surfaces are provided be used to the cell piece retainer 4 that holds hetero-junction solar cell sheet 3, cell piece retainer 4 is made by metal frame, can effectively reduce like this area of contact of cell piece retainer 4 and cell piece 3, reduce the crawler belt seal after drying.Cause the fragmentation of cell piece in order to prevent hetero-junction solar cell sheet 3 from clashing into cell piece retainer bottom when slipping into cell piece retainer 4, cell piece retainer 4 bottoms are stained with elastic buffer adhesive tape 5.Prime belt conveyor 1 comprises the first rotating shaft 11, the second rotating shaft 12 and belt 13, belt 13 is arranged on the two ends of the first rotating shaft 11 and the second rotating shaft 12, the first rotating shaft 11 is by the first stent support 14, the first rotating shaft 11 can be in the 14 interior rotations of the first support, the second rotating shaft 12 is supported by the second support 15, the second rotating shaft 12 can be in the 15 interior rotations of the second support, and the second support 14 lower ends are provided with vertical cylinder 16.Prime belt conveyor 1 level attitude is higher than conveyor belt of baking oven 2, after hetero-junction solar cell sheet 3 after the screen printing is sent to prime belt conveyor 1 by belt conveyor, vertical cylinder 16 activities under the second support 15, reduce the height of the second support 15, so that originally be inclined to certain angle for the prime belt conveyor 1 that is horizontal to the second rotating shaft 12.Hetero-junction solar cell sheet 3 is changed into tilting to transmit by original horizontal transmission when prime belt conveyor 1 is delivered to conveyor belt of baking oven 2 like this, hetero-junction solar cell sheet 3 can overcome certain resistance at cell piece retainer 4 internal cause hetero-junction solar cell sheets 3 self gravitations along the component of cell piece retainer 4 directions, so that hetero-junction solar cell sheet 3 is more prone to such an extent that slip into cell piece retainer 4 inside, and can enter fully completely cell piece retainer 4, reduce the possibility that drops.
