Description
Technical field
The utility model relates to texturing equipment for silicon chip technical field, particularly a kind of Novel Delivery roller for silicon chip chain type texturing.
Background technology
An important step of crystal silicon solar batteries manufacture is making herbs into wool, making herbs into wool can make silicon chip surface form rough microstructure, when solar light irradiation is at silicon chip, the matte risen and fallen makes light generation multiple reflections and refraction, more sunlight is made to incide in silicon chip, improve the transformation efficiency of cell piece, the method for silicon wafer wool making is reacted by corrosive liquid and silicon chip, obtains the matte texture of vermiform or pyramid shape after reaction.
Chain type texturing is the making herbs into wool mode that current silicon chip is conventional, and when chain type texturing, silicon chip is immersed in corrosive liquid, in the support of roller and advance under driving.Chemical reaction produces bubble, is attached to below silicon chip, along with silicon chip moves together.Size and the distribution situation of bubble have a great impact matte.Bubble distribution is uneven will directly cause the uneven of making herbs into wool matte.Bubble crosses conference makes the silicon chip above bubble not have bubble to block and not reach corrosive liquid, if simultaneously silicon chip and roller contact overlong time, the underaction of silicon chip and corrosive liquid, easily forms rolling wheel stamp.
For solving the problem, the documents 1(patent No.: CN201320479577) a kind of transmitting device for crystal silicon chip making herbs into wool is proposed, it is characterized in that on roller, cover has two O molded cannula, two described O molded cannula can arbitrarily movement on roller.In the program, between the position of O molded cannula contact on silicon chip surface and other position, the adsorbed state of bubble has notable difference.Therefore, the position contacted with O molded cannula will produce obvious rolling wheel stamp.The documents 2(patent No.: the roller 201220336257) proposing a kind of polysilicon etching tank, its feature is that equal diameter is cylindrical at the body with roller., be linear contact lay between silicon chip and roller.On roller axial direction, the distribution of bubble is more even, can avoid the rolling wheel stamp occurred in documents 1.But in the silicon chip direction of motion, bubble will be squeezed from front to back by roller.By the impact that bubble covers, the reaction of silicon chip rear portion, not as fully anterior, easily causes situation uneven before and after silicon wafer suede.The documents 3(patent No.: CN20130875651) a kind of polycrystalline silicon solar cell etching device roller is proposed, it is characterized in that this roller is cylindrical long barrel structure, cylindrical long barrel structure periphery is evenly provided with frosted texture, and each frosted texture forms a circle around long cylinder.With similar than documents 2, in the program, bubble will be subject to the exclusion of roller and assemble and silicon chip rear portion, causes matte uneven.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of Novel Delivery roller for silicon chip chain type texturing, when using this roller carry out the transmission of silicon wafer wool making and support, can effectively avoid silicon chip surface to occur rolling wheel stamp, make matte more even simultaneously.
The utility model in order to the technical scheme solving its technical problem and adopt is: a kind of Novel Delivery roller for silicon chip chain type texturing, the one or both ends of described conveying roller are provided with gear, be engaged with the driving-chain of chain type texturing groove or driving belt, described conveying roller is cylindrical-shaped structure or cylinder-like structure, cylindrical-shaped structure or cylinder-like structure surface are provided with projection, described projection is prismatic, rectangle, honeycombed or be randomly distributed in described cylindrical-shaped structure or cylinder-like structure surface.
As further improvement of the utility model, the diameter of described cylindrical-shaped structure and the external diameter of described cylinder-like structure are 1 to 5 centimetre.
As further improvement of the utility model, described cylindrical-shaped structure and the length of cylinder-like structure are 12.5 to 300 centimetres.
As further improvement of the utility model, described projection spacing is between any two 0.2 to 30 millimeter.
As further improvement of the utility model, the height of described projection is 0.2 to 5 millimeter.
As further improvement of the utility model, described projection spacing is between any two 0.5 to 1 millimeter.
The beneficial effects of the utility model are: the roller surface that the utility model proposes is provided with projection, and make the time of the same position of silicon chip and protuberance contacts very short, each position of silicon chip can effectively contact with corrosive liquid, thus solve the problem of rolling wheel stamp; In addition, the bubble produced during silicon chip and corrosive liquid react is subject to the extruding of projection, air pocket is made to split into minute bubbles, simultaneously, bubble is squeezed and moves in the projection of random distribution, the bubble of some can be discharged bottom silicon chip, effectively alleviates bottom silicon chip and produces the uneven problem of corrosion because bubble is piled up, thus make matte evenly.

Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection range.
For making the utility model brighter understandable, now lifting a preferred embodiment, and coordinating accompanying drawing to describe in detail.
Embodiment: Fig. 1 is a kind of apparatus structure of the present utility model, conveying roller 1 is cylindrical-shaped structure 12, the diameter of cylindrical-shaped structure 12 is 3 centimetres, length is 150 centimetres, cylindrical-shaped structure 12 is provided with the projection 11 of needle-like, be circular bottom the projection 11 of needle-like, the projection 11 of needle-like is randomly dispersed in cylindrical-shaped structure 12 surface, the projection 11 of needle-like is highly 1 millimeter, average distance between the projection 11 of needle-like is 1 millimeter, one of conveying roller 1 is provided with gear, gear agrees with mutually with the upper driving-chain of Heidi Schmid wool-weaving machine equipment in use, chain drives roller 1 to rotate, silicon chip is driven by the projection 11 of needle-like and travels forward above roller 1, movement velocity is identical with the rotational line speed at projection 11 top of roller 1 needle-like, the movement velocity of silicon chip is controlled by the velocity of rotation controlling driving-chain, be convenient to the loss of weight and the reflectivity that regulate silicon chip.In the motion process of silicon chip, the top of the projection 11 of needle-like contacts with silicon chip, the area of contact is the area at projection 11 top of needle-like, owing to being almost point cantact, the time of contact is also very short, in the process of silicon slice corrosion, the bubble that silicon chip and corrosive liquid chemical reaction produce is attached to the lower surface of silicon chip, bubble is subject to the extruding of the projection 11 of intensive needle-like, minute bubbles are become from air pocket after segmentation, and be more evenly distributed in silicon chip lower surface, bubble is subject to the extruding force of projection 11 side direction of needle-like simultaneously, bubble meeting random motion, some bubble is finally separated with silicon chip.
In this process, the time that each position of silicon chip contacts with the projection 11 of needle-like is very short, silicon chip is made all to have good contact with corrosive liquid at each position, effectively can solve the problem of rolling wheel stamp, in the process of simultaneously reacting at silicon chip and corrosive liquid, a part of air pocket is divided into minute bubbles and in the random motion of silicon chip lower surface, and a part of bubble is separated with silicon chip, which greatly enhances the uniformity of silicon wafer wool making, improve making herbs into wool effect.Good pile effects has very large effect to the quality promoting cell piece.
