Abstract
The invention relates to a mesh belt of a sintering furnace. The mesh belt comprises a mesh belt body. The mesh belt body is divided into a left edge area, a left connection area, a center bearing area, a right connection area and a right edge area sequentially from left to right in the width direction. The left edge area and the right edge area are distributed on the two sides of the center bearing area symmetrically. The left connection area and the right connection area are also distributed on the two sides of the center bearing area symmetrically. The mesh wire density of the left connection area and the right connection area is smaller than that of the center bearing area, the left edge area and the right edge area. According to the mesh belt, mesh wire density of the left connection area and the right connection area is reduced of the mesh belt, and blocking of the mesh belt to the surface of a silicon wafer is also reduced under the circumstance that the supporting strength of the mesh belt to the silicon wafer during walking is ensured, so that the sintering quality is improved, meanwhile, temperature loss in the sintering furnace is reduced, the stability of process temperature is improved, heating power consumption of the sintering furnace is reduced, and the manufacturing cost of the mesh belt is reduced.
Description
Technical field
The present invention relates to solar battery sheet production technical field, especially a kind of sintering furnace net belt.
Background technology
A kind of sintering furnace net belt, crystal silicon solar energy battery is related in existing cell piece production technology
Sheet after screen printing, the most all can use guipure to be sintered the behaviour of operation in being transported to sintering furnace
Make, so that the electrode of crystal silicon cell and printing forms good Ohmic contact, thus form solar-electricity
The positive and negative electrode in pond, guipure passes through power transmission shaft in sintering furnace inner-outer circulation transmission.As it is shown in figure 1, it is existing
Sintering furnace net belt be to be shaped with certain density weave by twine, use infrared lamp to silicon in sintering furnace
Sheet heats, and owing to twine density is relatively big, twine has the most large-area blocking to silicon chip contact surface,
Shielded region is difficult to be heated to, it is necessary to sintering in-furnace temperature is raised and can be only achieved effect, additionally net
Band material is metal, and guipure circulates in transmission inside and outside sintering furnace, and twine density is the biggest, and the area of twine is more
Greatly, it is the most to the outside heat energy taken away that guipure enters sintering furnace interior recirculation, easily causes work in stove
Skill temperature is unstable, needs sintering furnace hot operation to ensure that in-furnace temperature is stable, expends more electric energy.
Summary of the invention
The technical problem to be solved in the present invention is: relatively big in order to solve the twine density of existing sintering furnace net belt,
Easily cover silicon chip surface and cause sintering bad, to outside meeting inside sintering furnace in guipure cyclic process
Siphon away partial heat energy, cause technological temperature in stove unstable and the problem of more electric energy loss, it is provided that a kind of burn
Freezing of a furnace guipure.
The technical solution adopted for the present invention to solve the technical problems is: a kind of sintering furnace net belt, including guipure
Body, described guipure body is divided into left hand edge district, left bonding pad, center from left to right at width
Supporting region, right bonding pad and right hand edge district, described left hand edge district and right hand edge district are symmetrically distributed in center carrying
The both sides in district, described left bonding pad and right bonding pad are also symmetrically distributed in the both sides of center supporting region, a described left side
The twine density of bonding pad and right bonding pad is close less than the twine in center supporting region and left hand edge district and right hand edge district
Degree.Center supporting region is used for supporting silicon chip, it is necessary to assure guipure center intensity in the process of walking, therefore
Center supporting region keeps existing twine density constant, in order to prevent the edge curl of guipure from deforming, and left hand edge
District and right hand edge district also keep original twine density, to keep the edge strength of guipure；Left bonding pad and the right side
The twine density of bonding pad is less than center supporting region and the twine density in left hand edge district and right hand edge district, decreases
Silicon chip back side is blocked by guipure, it is to avoid affect sintering quality because excessively blocking, simultaneously because left and right connects
The twine density in district is little, and area is little, reduces guipure cost, and in cyclic process, the guipure of cooling is from stove
The heat energy absorbed time in entrance stove has declined, and reduces temperature loss, improves uniform temperature.
The invention has the beneficial effects as follows, present invention decreases the twine density of bonding pad, guipure left and right, ensureing
During guipure walking to the support strength of silicon chip in the case of, decrease again guipure silicon chip surface blocked,
Improve sintering quality, decrease the temperature loss in sintering furnace simultaneously, improve the stability of technological temperature,
Reduce sintering furnace heating power consumption, reduce the manufacturing cost of guipure.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of existing sintering furnace net belt；
Fig. 2 is the structural representation of sintering furnace net belt of the present invention.
In figure: 1. left hand edge district, the most left bonding pad, 3. center supporting region, the rightest bonding pad, 5. right hand edge
District, 6. twine.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification,
The basic structure of the present invention is described the most in a schematic way, and therefore it only shows the composition relevant with the present invention.
As in figure 2 it is shown, a kind of sintering furnace net belt, including guipure body, described guipure body is at width
It is divided into left hand edge district 1, left bonding pad 2, center supporting region 3, right bonding pad 4 and the right from left to right
Edge district 5, described left hand edge district 1 and right hand edge district 5 are symmetrically distributed in the both sides of center supporting region 3, a described left side
Bonding pad 2 and right bonding pad 4 are also symmetrically distributed in the both sides of center supporting region 3, described left bonding pad 2 He
Twine 6 density of right bonding pad 4 is less than center supporting region 3 and the twine 6 in left hand edge district 1 and right hand edge district 5
Density.Center supporting region 3 is for supporting silicon chip, it is necessary to assure guipure center intensity in the process of walking,
Therefore center supporting region 3 keeps existing twine 6 density constant, in order to prevent the edge curl of guipure from deforming,
Left hand edge district 1 and right hand edge district 5 also keep original twine 6 density, to keep the edge strength of guipure；
Twine 6 density of left bonding pad 2 and right bonding pad 4 is less than center supporting region 3 and left hand edge district 1 and the right
Twine 6 density in edge district 5, decreases guipure and blocks silicon chip back side, it is to avoid affect because excessively blocking
Sintering quality, simultaneously because twine 6 density of bonding pad, left and right 4 is little, area is little, reduces guipure cost,
The heat energy absorbed time in the guipure of cooling enters stove from stove in cyclic process has declined, and reduces temperature
Loss, improves uniform temperature.
With the above-mentioned desirable embodiment according to the present invention for enlightenment, by above-mentioned description, related work
Personnel can carry out various change and amendment completely in the range of without departing from this invention technological thought.
The content that the technical scope of this invention is not limited in description, it is necessary to according to right
Determine its technical scope.
