Abstract

The utility model discloses a sintering furnace. The sintering furnace comprises a drying area furnace belt, a sintering area furnace belt, a set of front face infra-red heating lamp tubes and a set of back face infra-red heating lamp tubes, wherein the belt speed of the drying area furnace belt and the belt speed of the sintering area furnace belt are controlled by two motors respectively, and the set of front face infra-red heating lamp tubes and the set of back face infra-red heating lamp tubes are located at the upper portion and the lower portion of the sintering area furnace belt respectively and are controlled by two temperature control modules respectively. The belt speed of the drying area furnace belt and the belt speed of the sintering area furnace belt can be controlled independently, organic matters in a drying area are guaranteed to be sufficiently combusted, and battery pieces in a sintering area are guaranteed to form good ohmic contact. A heating system in the sintering area is composed of the two sets of infra-red heating lamp tubes, and therefore the sintering temperatures can be separately controlled according to different temperature ranges required by front face silver paste sintering and back face silver paste sintering, the efficiency of the sintered battery pieces is improved, and good performance of a crystalline silicon solar cell is guaranteed.

Description

A kind of sintering furnace
Technical field
The utility model relates to a kind of sintering furnace.
Background technology
In the sintering process of crystal-silicon solar cell, usually technology is divided into four-stage: 1, combustion of organic matter stage, 2, the temperature rise period, 3, the peak temperature interval, 4, between cooling area; The control of combustion of organic matter phase temperature is about 300 ℃, temperature is too high or too low unfavorable to battery sheet formation Ohmic contact, temperature rise period requires aluminium back of the body field to be heated evenly and fully, the assurance alusil alloy forms, formation and the Ohmic contact of the positive silver-colored silicon alloy of peak temperature direct relation, bigger to the crystal silicon solar energy battery performance impact, temperature descending section guarantees the alloy cooling and reaches the pulling force requirement: the temperature of alusil alloy is 577 ℃, and the temperature of silver-colored silicon alloy is 835 ℃.
Used sintering furnace has following shortcoming:
1, the sintering furnace furnace zone has only an Electric Machine Control belt speed, and sintering process four-stage belt speed is the same, can't control belt speed and sintering temperature separately to baking zone and sintering zone;
2, the heat lamp pipe temperature of control sintering zone furnace temperature can't arrange respectively, and temperature is identical when causing positive electrode silver slurry with the back electric field aluminum pulp sintering.
The utility model content
The utility model purpose: the purpose of this utility model is at the deficiencies in the prior art, and a kind of sintering furnace that can regulate the belt speed in baking zone furnace zone and furnace zone, sintering zone respectively and can separately control baking zone and sintering zone temperature is provided.
Technical scheme: a kind of sintering furnace described in the utility model, comprise baking zone furnace zone, furnace zone, sintering zone, one group of front heat lamp pipe and one group of back side heat lamp pipe, baking zone furnace zone and furnace zone, sintering zone are respectively by two Electric Machine Control belt speed, one group of front heat lamp pipe and one group of back side heat lamp pipe lay respectively at the upper and lower in furnace zone, sintering zone, and are controlled by two temperature control modules respectively.
Preferably, the motor of control baking zone furnace zone belt speed is the motor that rotating speed is lower than control furnace zone, sintering zone belt speed motor speed, so the belt speed in described baking zone furnace zone is lower than the belt speed in furnace zone, described sintering zone, the belt speed in baking zone furnace zone slightly slowly can be with the abundant after-flame of organic matter in the slurry, and the belt speed in furnace zone, sintering zone can guarantee that slightly soon the battery sheet forms good Ohmic contact.
Beneficial effect: 1, the belt speed in the utility model sintering furnace baking zone furnace zone and furnace zone, sintering zone can separately be controlled, and guarantees to form good Ohmic contact at the battery sheet of the abundant after-flame of baking zone organic matter and sintering zone; 2, the heating system of sintering zone is made up of two groups of heat lamp pipes, required different temperatures scope during like this according to front side silver paste sintering and back side aluminium paste sintering, can separately control its sintering temperature, the efficient of battery sheet behind the lifting sintering, the superperformance of assurance crystal silicon solar energy battery.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
Embodiment:A kind of sintering furnace, as shown in Figure 1, comprise baking zone furnace zone 1, furnace zone, sintering zone 2, one group of front heat lamp pipe 3 and one group of back side heat lamp pipe 4, baking zone furnace zone 1 and furnace zone, sintering zone 2 are respectively by two Electric Machine Control belt speed, the belt speed in baking zone furnace zone 1 is lower than the belt speed in furnace zone, described sintering zone 2, the belt speed in baking zone furnace zone 1 slightly slowly can be with the abundant after-flame of organic matter in the slurry, and the belt speed in furnace zone, sintering zone 2 can guarantee that slightly soon the battery sheet forms good Ohmic contact.
One group of front heat lamp pipe 3 and one group of back side heat lamp pipe 4 lay respectively at the upper and lower in furnace zone, sintering zone, and control its heating power by two temperature control modules respectively, the temperature of one group of front heat lamp pipe 3 is arranged on 850 ℃ to 880 ℃, the formation and the Ohmic contact thereof that guarantee positive silver-colored silicon alloy are good, the temperature of one group of back side heat lamp pipe 4 is arranged on 600 ℃ to 650 ℃, guarantees that formation and the Ohmic contact thereof of back side alusil alloy is good.
As mentioned above, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make various variations in the form and details to it.
