Abstract
The utility model discloses a continuous annealing device for a copper strip used for a solar photovoltaic solder strip. The continuous annealing device is arranged before a copper strip base material tinning production line. The continuous annealing device comprises a copper strip paying-off end, an annealing pipeline, an electrical heating box, a cooling water tank and a copper strip taking-up end behind the cooling water tank, wherein the copper strip base material at the copper strip paying-off end enters the annealing pipeline, the annealing pipeline extends out and passes through the heating zone of the electrical heating box and then continues to extend forwards and enters the cooling water tank, the pipeline between the cooling water tank and the electrical heating box is a natural cooling pipeline, and the natural cooling pipeline is communicated with a nitrogen filler pipeline. After the copper base material is treated by the device, the copper strip hardness is efficiently lowered, so that softer copper strip base material with uniform hardness is obtained.
Description
Technical field
The utility model relates to a kind of annealing device, particularly a kind of photovoltaic welding continuous annealing apparatus of copper strips.
Background technology
The welding that photovoltaic module uses need carry out anneal to copper strips when process for processing, the general whole rosette copper band annealing way of bell-jar that adopts carries out anneal in the industry.This anneal mode is handled the hardness of back copper strips usually at 60HV, the hardness of the welding of producing can be than higher, the fragmentation rate of the hardness of welding and battery sheet has comparatively directly relation, hardness is high more, battery sheet disruptive possibility in the time of will being increased in welding or lamination, hardness is low more, and relatively the fragmentation rate is just lower, and the fragmentation rate is high more, and the cost of photovoltaic module manufacturer also will increase greatly.
Summary of the invention
Goal of the invention of the present utility model is in order to overcome the defective in the above-mentioned background technology, a kind of continuous annealing apparatus that can overcome the photovoltaic module welding of above-mentioned shortcoming with copper strips to be provided.
The technical solution of the utility model is: a kind of photovoltaic welding continuous annealing apparatus of copper strips, be arranged on before the zinc-plated product line of copper strips base material, comprise copper strips unwrapping wire end, the annealing pipeline, the electrically heated case, cooling water tank and the copper strips take-up end that the cooling water tank postorder is set, the copper strips base material of copper strips unwrapping wire end enters the annealing pipeline, continue to extend forward and enter cooling water tank in the annealing pipeline extend past electrically heated case heating region, this segment pipe between cooling water tank and electrically heated case is the naturally cooling pipeline, its length is: 85～95CM,, this section naturally cooling pipeline also is communicated with the nitrogen flow in pipes.
Described electrically heated case is provided with the thermopair that gos deep into to its heating region, and the electrically heated case also is connected to electric control box, and thermopair transfers to electric control box with the signal that collects.
Described annealing pipe is the stainless steel annealing pipe.
The utility model is abandoned the bell-jar annealing way of ordinary copper base material, adopt continuous annealing mode, base material is pulled out with the continuous annealing pipeline of certain speed by certain-length, the sectional anneal of carrying out, by controlling corresponding time, speed and temperature well, can obtain the softer (＜50HV of hardness
)And uniform copper base material.Photovoltaic module is 200 μ m with the original thickness of battery sheet, battery sheet fragmentation rate is 7 ‰, now the battery sheet thickness that uses is 180 μ m, and fragmentation rate should be higher routinely, and the battery sheet fragmentation rate when using the ultra-soft welding welding of annealing back copper strips production now is 3 ‰.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein: 1, copper strips base material, 2, thermal insulation layer, 3, the electrically heated case, 4, the stainless steel annealing pipe, 5, electric heating panel, 6, thermopair, 7, electric control box, 8, the naturally cooling district, 9, the nitrogen flow in pipes, 10, cooling water tank, 11, water inlet pipe and water outlet pipe, 12, thermopair, 13 water pump controlling boxs.
Embodiment
The utility model as shown in Figure 1, be arranged on before the zinc-plated product line of copper strips base material, copper strips base material (1) enters in the stainless steel annealing pipe (4) after being derived by pay off rack, is lined with the electrically heated case (3) of thermal insulation layer (2) in stainless steel annealing pipe (4) gos deep into extremely forward.
In electrically heated case (3), arranged two rows altogether, nine stainless steel annealing pipes of every row, 18 interior copper strips base materials of stainless steel annealing pipe enter simultaneously and heat.The temperature that has a thermopair (6) that probes in the case can survey at any time in the electrically heated case in position, electrically heated box top is transferred to electric control box (7), need in advance copper strips base material according to different size to configure different Heating temperatures before the production so that the temperature that detects by thermopair is compared, electric control box can control be clipped in stainless steel tube up and down and the electric heating panel in middle layer carry out work, can guarantee that so the interior temperature of electrically heated case remains under the predefined state of temperature.
When the speed of three meters of the substrate passed per minutes of copper strips through the naturally cooling pipeline (8) below behind electrically heated case (3), entering, also connecting on the naturally cooling pipeline (8) has nitrogen flow in pipes (9), not oxidized in heat-processed in order to the protection copper strips.
Enter cooling water tank (10) behind the substrate passed naturally cooling pipeline of copper strips (8) at last, be full of water in the cooling water tank and be used for the interior copper strips base material of further cooling duct, copper strips after water temperature is along with heating constantly enters and after temperature raises, device can detect actual temperature in the test of cooling water tank top to the another thermopair (12) of water tank inside, can carry out one water in the cooling water tank and external water source carried out an exchange by water inlet pipe and water outlet pipe (11) if actual temperature is higher than when setting temperature in the water pump controlling box water pump, reach the effect that the cooling water tank temperature reduces.The copper strips base material of finishing whole annealing process at last from the stainless steel tube end come out the back by the power traction of take-up mechanism to the take-up reel to finish whole annealing process.
