Abstract
The invention relates to a silicon chip cleaning and texturing slot, which comprises a slot body and a heating pipe, wherein a support frame of the heating pipe is arranged at the slot bottom of the slot body, and the distance from a position limiting slot of the heating pipe to the slot bottom is 1/5-1/4 of the height of liquid level. As the support frame of the heating pipe is increased in the silicon chip cleaning and texturing slot, the position of the heating pipe is limited by the position limiting slot of the heating pipe on the support frame of the heating pipe, and the support frame of the heating pipe can separate the heating pipe from the slot wall and the slot bottom of the cleaning and texturing slot, thereby avoiding the direct contact between the heating pipe and the slot wall and the slot bottom of the cleaning and texturing slot and ensuring that the cleaning and texturing slot has no burning loss due to high temperature. The temperature on the heating pipe can be uniformly diffused to the periphery of solution in the slot when heating, thereby ensuring the uniformity of the temperature of the solution in the slot and simultaneously ensuring the safety of the production.
Description
[technical field]
The present invention relates to a kind of battery sheet production device, relate in particular to the silicon chip of solar cell cleaning and texturing slot.
[background technology]
Sun power is a kind of radiating capacity, compares with other energy, and that sun power can not produce is poisonous, obnoxious flavour and waste residue, and it is a kind of green energy resource, thereby does not pollute the environment.Sunlight is available anywhere simultaneously, and is easy to use, safe, with low cost, can regenerate.But it must just can be converted to electric energy by means of energy converter, this energy converter that transform light energy is become electric energy, be exactly solar cell,, proposed new requirement for the quality and the cost of solar product along with the continuous lifting of photovoltaic industrial technology.And the raw material of making solar cell is the silicon material, the silicon material is drawn into silicon rod, silicon chip is prepared from by the multi-line cutting machine cutting by silicon rod, the silicon chip that cuts, impurity and surface irregularities such as surface attachment mortar, therefore before making battery, the surface treatment of silicon chip be to carry out earlier, the matting of silicon chip and the surface corrosion of silicon chip comprised.Matting is in order to remove the various impurity on the silicon chip, and the purpose of surface corrosion is the cutting damage of removing silicon chip surface, obtains to be fit to the silicon face that the system knot requires.The performance and the state of silicon chip surface before the system knot directly influence the characteristic of knot, thereby influence the performance of finished product battery.Silicon chip promptly begins making herbs into wool through after the surface treatment, leather producing process is an of paramount importance ring in the whole production line, its objective is that carrying out texturing by the method for chemical corrosion at silicon chip surface handles, form good sunken photoeffect, reduce the silicon chip surface emittance.General production technique is to adopt slot type making herbs into wool at present, in higher temperature environment, carry out anisotropic etch with KOH or NaOH solution, erode away the pyramid that is similar to pyramid structure at silicon chip surface, realize the multiple reflection of incident light, reduce surface albedo.And the homogeneity in the homogeneity of groove internal corrosion liquid and temperature field has just determined the stability of mass industrialized production, so the stability in the temperature field in the technological process is an of paramount importance factor of influence.The type of heating of rinse bath and texturing slot is by stainless steel tubular type well heater or the heating of Teflon tubular heater at present, stainless steel tubular type well heater or Teflon tubular heater are placed directly in the bottom of rinse bath and texturing slot, layer overlay stainless steel plate on well heater, again silicon slice placed on stainless steel plate, because the material of rinse bath and texturing slot is the PP plastics, its heatproof is no more than 275 ℃, heating tube and bottom land directly contacted to cause bottom land to burn out, thereby it is accidents caused, simultaneously, heating tube directly is placed on bottom land, can causes the temperature diffusion slowly with inhomogeneous.
[summary of the invention]
In order to overcome the deficiency that existing cleaning and texturing slot exists, the invention provides a kind of solar silicon wafers cleaning and texturing slot.Adopt this cleaning and texturing slot, it can either prevent effectively that heating tube from burning out bottom land, can guarantee the homogeneity of fluid temperature in the groove again.
The technical solution used in the present invention is:
Silicon chip cleaning and texturing slot of the present invention, it comprises cell body and heating tube, it is characterized in that: be provided with the heating tube bracing frame on the bottom land of cell body.
Further, described heating tube bracing frame is made up of the Teflon unit of plastic of two symmetrical distributions, offers the heating tube stopper slot on every Teflon unit of plastic, and the heating tube stopper slot is 1/5～1/4 of the interior solution height of groove to the height of bottom land.
Owing in silicon chip cleaning and texturing slot, set up the heating tube bracing frame, heating tube is spacing by the heating tube stopper slot on the heating tube bracing frame, the heating tube bracing frame separates the cell wall and the bottom land of heating tube and cleaning and texturing slot, avoided heating tube directly to contact with bottom land, guaranteed that cleaning and texturing slot is not by the high temperature scaling loss with the cell wall of cleaning and texturing slot.During heating, the temperature on the heating tube can be equably in groove solution around diffusion, guaranteed the homogeneity of solution temperature in the groove also to have guaranteed the safety of producing simultaneously.

Fig. 1 is the prior art constructions synoptic diagram, and promptly heating tube directly is placed in the silicon chip cleaning and texturing slot;
Fig. 2, Fig. 3 are synoptic diagram of the present invention,
Be that heating tube is placed on the bracing frame of cleaning and texturing slot internal heating pipe;
Fig. 3 is the right view of Fig. 2;
Among the figure: the 1-cell body; The 2-heating tube; The 3-bottom land; 4-heating tube bracing frame; 5-heating tube stopper slot; The 6-cell wall.
[embodiment]
Described silicon chip cleaning and texturing slot, as Fig. 2, shown in Figure 3, it is made up of cell body 1, heating tube 2 and heating tube bracing frame 4, described heating tube bracing frame 4 is made up of the Teflon unit of plastic of two symmetrical distributions, on every Teflon unit of plastic, offer heating tube stopper slot 5, heating tube bracing frame 4 is placed on the bottom of cell body 1, and heating tube bracing frame 4 separates cell wall 6 and the bottom land 3 of heating tube 2 with cleaning and texturing slot, and heating tube stopper slot 5 is 1/4 of the interior solution height of groove to the height of bottom land 3.
