Abstract
The utility model discloses a kind of no five main grid solar cell string welding equipments of pressing.Tin copper strips will be applied by briquetting to compress on the table, and passing through tensioning wheel makes painting tin copper strips be stretched in solar cell on piece, thereby realizes the purpose for instead of the pressure of pressing painting tin copper strips being made to be close to solar battery sheet by applying tin copper strips tension.So as to no longer need using pressing, avoid pressing damage and replace pressing, the damp production brought.
Description
Technical field
The utility model is related to solar cell manufacturing field, more particularly to a kind of five main grid solar cell string of no pressing
Welding equipment.
Background technology
Solar cell is applied in the daily of people as a kind of environmentally friendly and reproducible novel energy is just increasingly extensive
In life.Current solar cell generally is intended to several pieces of cell pieces connecting into battery strings by main gate line thereon to be tried again
With.A bar painting tin copper strips is typically welded in main gate line as confluence and connection bus.Initial solar cell string be by
What manual welding formed.Current welder widely used automation equipment.During production, feeding device will be put on grid line
The solar cell string for putting painting tin copper strips is placed on the table, and the heating unit of top declines so that heating unit bottom surface
On pressing push down and apply tin copper strips, then heating unit is started to work, and heating applies tin copper strips and solar battery sheet so that applies tin
The silver paste fusion of solar cell on piece below copper strips, then stops heating, and silver paste cooling is welded on solar energy by tin copper strips is applied
On cell piece.In order to avoid rosin joint, solder skip pressing are set along painting tin copper strips extending direction close-packed arrays.Although such mode
Automatic welding is realized, but pressing under hot and cold alternation due to working for a long time, it is easy to it damages, therefore often to replace pressing,
So as to influence to produce.
Utility model content
In order to which drawbacks described above and insufficient the utility model is overcome to provide following technical scheme：A kind of five main grid sun of no pressing
Energy battery strings welding equipment, including rack and feeding device, the rack is equipped with workbench, and the workbench left and right sides is
Equipped with briquetting, the briquetting connects the rack by the first telescopic device, and the workbench left and right sides, which are equipped with, to be accommodated
Space, the accommodation space is interior to be equipped with tensioning wheel, the quantity of the tensioning wheel and the quantity of painting tin copper strips in solar cell string
Identical, each tensioning wheel connects the workbench by the second telescopic device, and second telescopic device, which is equipped with, to be surveyed
For controlling the Tensity size applied on tin copper strips, liftable heating unit is provided with above the workbench for force snesor.
Preferably, the seamed edge contacted on the briquetting with the painting tin copper strips is equipped with circular arc chamfering.It can so keep away
Exempt from painting tin copper strips to be cut off by seamed edge in tensioning
Preferably, the briquetting is made of rubber or silica gel.It so on the one hand reduces and applies the probability that tin copper strips is pressed down,
Increase briquetting simultaneously and apply the frictional force of tin copper strips, avoid causing to apply the sliding of tin copper strips due to tension.
Preferably, first telescopic device and the second telescopic device are cylinder, hydraulic cylinder, electric telescopic rod wherein it
One or combination.
Compared with prior art, the utility model has the advantages that：The utility model will apply tin copper by briquetting
Band compresses on the table, and passing through tensioning wheel makes painting tin copper strips be stretched in solar cell on piece, thereby realizes and passes through
Apply the purpose that tin copper strips tension replaces the pressure of pressing that painting tin copper strips is made to be close to solar battery sheet.So as to no longer need using pressure
Pin avoids pressing damage and replaces pressing, the damp production brought.
Description of the drawings
Fig. 1 is the schematic diagram that welding equipment is faced in specific embodiment of the present invention.
Fig. 2 is the schematic diagram of welding equipment side view in specific embodiment of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings, elaborate to specific embodiment of the present utility model.
As shown in Figure 1, 2, a kind of five main grid solar cell string welding equipment of no pressing, including rack and feeding device,
The rack is equipped with workbench 1, and 1 left and right sides of workbench is equipped with briquetting 2, and the briquetting 2 is by rubber or silica gel system
Into the briquetting 2 connects the rack by the first telescopic device 3, and 1 left and right sides of workbench are equipped with accommodation space
Tensioning wheel 4, the quantity of the tensioning wheel 4 and the number of painting tin copper strips 7 in solar cell string are equipped in 1a, the accommodation space 1a
Measure identical, each tensioning wheel 4 connects the workbench 1 by the second telescopic device 5, on second telescopic device 5
Equipped with force cell, for controlling the Tensity size applied on tin copper strips 7, the top of the workbench 1 is provided with liftable
Heating unit.
The seamed edge contacted on the briquetting 2 with the painting tin copper strips 7 is equipped with circular arc chamfering.
First telescopic device, 3 and second telescopic device 5 is one of cylinder, hydraulic cylinder, electric telescopic rod or group
It closes.
When welding equipment works, feeding device is by coated solder and lay the solar cell string of painting tin copper strips 7 and puts
It puts on workbench 1, applies tin copper strips 7 and hang down beyond the part of solar cell string from 1 left and right sides of workbench, briquetting 2 is the
Tin copper strips 7 will be applied under the driving of one telescopic device 3 to be pressed on workbench 1, then tensioning wheel 4 is in the drive of the second telescopic device 5
It is protruding under dynamic, tin copper strips 7 is applied so as to be tensioned, while the load cells monitor by being arranged on the second telescopic device 5
The tension of tin copper strips 7 is applied, so as to control the size of tensile force so that tensioning can be reached and apply tin copper strips, it is made to be pressed on the sun
On energy cell piece 8, while stress after applying tin copper strips 7 and solar battery sheet welding will not be caused excessive due to overtension again
And influence performance.After applying 7 tensioning of tin copper strips, heating unit 6 declines and heats so that solder, which melts, will apply tin copper strips 7 and the sun
Energy cell piece 8 welds together.
The utility model is described in detail above, but the utility model be not limited to it is described herein specific
Embodiment.It should be appreciated by those skilled in the art that in the case of without departing substantially from the scope of the utility model, other can be made more
Change and deform.The scope of protection of the utility model is defined by the following claims.
