Abstract
The utility model relates to a picked and placed solar battery component. The existing battery plates are connected with each other in a welding way. The picked and placed solar battery component consists of a plurality of unit components, wherein each unit component consists of a solar battery plate, a metal welding rod and conductive adhesive. The conductive adhesive is arranged between the solar battery plate and the metal welding rod. The picked and placed solar battery component has the advantages of small warpage of the battery plate and low breaking rate due to no use of electric iron and low baking temperature, greatly reduces the rate of insufficient solder and missing solder, is particularly suitable for picking and placing a lead-free solder strip, solves the problem of insufficient solder and missing solder of the lead-free solder strip, improves the reliability of the component product, is particularly suitable for packing a thin plate and is capable of being suitable for the development tendency that a silicon wafer gets thinner and thinner in the industry as the electric iron is not utilized for high-temperature soldering, and greatly improves the appearance of the component as the surface of a tin bar is not treated.
Description
Technical field
The utility model relates to field of solar energy, particularly a kind of solar module that adopts mounting method.
Background technology
After the battery sheet comes out from the monomer Workshop Production, must be by the effect of its extensive generating of encapsulation competence exertion; First procedure of encapsulation is welding sequence, i.e. utilization is coated with tin copper strips (or claiming tin bar) and by the mode that electric iron welds the silver electrode that the tin on the tin bar melts on back and the battery sheet grid line is formed the alloy with certain conductance.Each sheet battery unit promptly is to be together in series or parallel by such mode, has realized being connected of structure and electric two aspects; Then various encapsulating materials are carried out lamination in a certain order, afterwards it is carried out treating lamination after the electrical property preliminary survey.This is the packaged type that present domestic most of component package enterprise adopts.
In the mode of above-mentioned electric iron welding, there is following several problem, one is the welding temperature height, the thermal coefficient of expansion of welding rod and battery sheet can not be in full accord, can cause occurring in process of production fragment like this, though fragment rate can be controlled at 0.3-0.5%, the annual loss that causes also is very huge; The 2nd, whole welding process is manually to operate fully, can cause rosin joint undoubtedly or leak the phenomenon of welding, and can't guarantee the high reliability of product; The 3rd, because employed welding rod is through after the electric iron welding, the phenomenon of piling tin or pouncing on tin can appear on the surface of tin bar, the weld appearance of assembly has been subjected to influence undoubtedly.
Along with the solar cell package technology make rapid progress and client's demand more and more, as: in order to reduce cost, silicon chip is more and more thinner; For product environmental protection more, require the interior tin bar of product not leaded; And client has the quality that increasing testing tool is controlled product, has high reliability or the like with regard to requiring to encapsulate the subassembly product that enterprise produces, and these require in case occur, and then above-mentioned three problems mentioning can be more and more obvious.
In the face of above-mentioned all problems, need find a kind of battery sheet method of attachment of welding of not needing.
Summary of the invention
The purpose of this utility model provides a kind of solar module that adopts mounting method, can make baking temperature low, and warpage is little, and fragment rate is low, is particularly suitable for the encapsulation of thin slice and unleaded tin bar; The generation of no rosin joint and leakage weldering has improved reliability of products; The process that mounts can guarantee zingy outward appearance.
The technical solution of the utility model is:
Adopt the solar module of mounting method, be made up of a plurality of unit pieces, each unit piece all is made up of solar battery sheet, metal electrode and conducting resinl; Wherein: be provided with conducting resinl between solar battery sheet and the metal electrode.
Advantage of the present utility model:
(1) owing to do not use electric iron, and baking temperature is low, and battery sheet warpage is little, and percentage of damage is low.
(2) greatly reduce the probability that rosin joint and leakage are welded, be particularly suitable for mounting of unleaded welding, solved and used unleaded welding rosin joint to leak the many problems of weldering, improved the reliability of subassembly product.
(3) owing to do not use the electric iron high-temperature soldering, be specially adapted to the encapsulation of thin slice, can adapt to the more and more thinner development trend of industry silicon chip.
(4) the tin bar surface is without any processing, and the assembly outward appearance greatly is improved.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Reference numeral: solar battery sheet 1, metal electrode 2, conducting resinl 3.
Embodiment
The solar module of embodiment 1, employing mounting method is made up of a plurality of unit pieces, and each unit piece all is made up of solar battery sheet 1, metal electrode 2 and conducting resinl 3; Wherein: be provided with conducting resinl 3 between solar battery sheet 1 and the metal electrode 2.
The solar module of embodiment 2, employing mounting method, wherein: metal electrode 2 can be copper bar, tin bar or zinc-plated copper bar.All the other are with embodiment 1.
Operation principle:
At first be ready to stand-by battery sheet, bonding jumper and conducting resinl.Point gum machine is opened, regulated each parameter, and stand-by conducting resinl is placed on the point gum machine ad-hoc location to best position.The battery sheet is placed on the position of fixing on the objective table of point gum machine.Start point gum machine and a glue is carried out in battery sheet main grid position according to the some glue program of setting.After having put glue on the main grid line of battery sheet, the main grid line of bonding jumper being aimed at the battery sheet is attached on the conducting resinl gently.The battery sheet that sticks bonding jumper is placed on following at a certain temperature the baking several seconds in the infra-red heat baking oven, makes the conducting resinl primary solidification so that carry out next step operation.Above-mentioned battery sheet is carried out back electrode point glue, and the battery sheet of then all back electrodes having been put glue is placed in the template, will go up a slice battery sheet successively and grow the back electrode place that bonding jumper partly is mounted on down a slice battery sheet gently.Realize the connection of both positive and negative polarity between the battery sheet.Above-mentioned battery strings is placed on one by one to descend to toast several seconds at a certain temperature in the infra-red heat baking oven, makes the conducting resinl primary solidification so that carry out next step operation.
Claims (2)
1. adopt the solar module of mounting method, be made up of a plurality of unit pieces, each unit piece all is made up of solar battery sheet (1), metal electrode (2) and conducting resinl (3); It is characterized in that: be provided with conducting resinl (3) between solar battery sheet (1) and the metal electrode (2).
2. the solar module of employing mounting method according to claim 1 is characterized in that: metal electrode (2) can be copper bar, tin bar or zinc-plated copper bar.
