Abstract
The utility model discloses a fixing device for detecting the adhesion of a solar cell piece metal electrode. The fixing device is characterized in that: the fixing device comprises a cover plate and a bottom plate which are connected through a shaft, the cover plate is provided with more than two grooves which are symmetrically distributed with a cover plate center line as an axis, the width of the grooves is in a range from 3 to 5 millimeters, the length of the grooves is the length of main gate lines of a cell piece to be detected, and a distance between two symmetrical grooves is a distance between the main gate lines of the cell piece to be detected. By employing the fixing device provided by the utility model to test the adhesion of the solar cell piece metal electrode, the cell piece can be fixed well, and only one operator can complete a test.
Description
Technical field
The utility model relates to a kind of fixture that is used to detect solar battery sheet metal electrode adhesive force, belongs to technical field of solar batteries.
Background technology
Along with the continuous development of photovoltaic industry, the quality of battery sheet improves constantly, to the quality of solar cell and having higher requirement of conversion efficiency.Solar battery sheet forms the metal positive and negative electrode after the process silk screen printing; Metal and brick combine to form silver-colored brick alloy and alusil alloy behind the sintering furnace sintering.After the solar cell finished product and before the shipment, need carry out a series of quality inspections such as efficient letter sorting, visual inspection, tensile test, to guarantee product quality.Wherein, tensile test is also claimed adhesive force test, is an important test item of solar module welding quality, when value of thrust during less than 300g, possibly represent that electrodes intensity is defective or electrode/solder joint tensile strength is defective.
Pull force test method commonly used is that the battery sheet that welding is accomplished is placed on the smooth table top; Select for use two plastic flat rulers to be parallel to the electrode both sides that electrode direction is attached to the battery sheet; Tight apart from electrode edge 1-2mm place with hand, use tensiometer to become 180 degree angles to apply pulling force with solder side the tin band, gradually strengthen pulling force; Speed with 30mm/s is pulled to the other end with the tin band from battery sheet one end; Be pulled to the process of the other end from battery sheet one end at the tin band, on battery plate electrode line, get the value of reading that 4 some record tensiometers show respectively, be respectively 1/4,2/4,3/4,4/4 place of electrode length.The shortcoming of the method needs the whole table top of levelling and fixes with ruler when being to do test, need another person to use tensiometer then, could accomplish test.
Summary of the invention
The purpose of the utility model provides a kind of being used to and detects the fixture that the solar cell sector-meeting belongs to electrode adhesion, makes the adhesive force test simple more, convenient.
In order to achieve the above object, the utility model provides a kind of fixture that is used to detect solar battery sheet metal electrode adhesive force, it is characterized in that; Comprise cover plate and base plate; Cover plate and base plate are connected through axle, and it is the axial symmetry grooves distributed that said cover plate is provided with more than two with the cover plate center line, and the width of said groove is 3-5mm; Length is the length of mesuring battary sheet main grid line, and the distance between two symmetrical grooves is the distance of mesuring battary main grid line.
Preferably, said cover plate and base plate are the rectangular slab of same size.
Preferably, it is the axial symmetry grooves distributed that said cover plate is provided with more than 4 with the cover plate center line, and the length of said groove is 156mm, and the distance of middle two grooves is 62.5mm, and the distance of two grooves in both sides is 78mm.
The utility model is processed fixed dimension, applicable to several kinds of battery sheet specifications, the for example solar battery sheets of 125 and 156 liang of grid commonly used.The fixture test solar battery sheet metal electrode adhesive force that adopts the utility model to provide can well the self-contained battery sheet, only needs operating personnel can accomplish test.
Description of drawings
Structural representation when Fig. 1 opens for a kind of fixture that is used to detect solar battery sheet metal electrode adhesive force.Among the figure:
1, cover plate; 3, first groove;
2, base plate; 4, second groove.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Embodiment
As shown in Figure 1; A kind of fixture that is used to detect solar battery sheet metal electrode adhesive force that provides for utility model; Comprise cover plate 1 and base plate 2, cover plate 1 flexibly connects through screw, nut with base plate 2, and said cover plate 1 is the thick rigid plastic sheet of 1cm of two surfacings with base plate 2.There are 4 to be the axial symmetry grooves distributed on the cover plate 1, every wide 4cm of groove, long 156cm with the cover plate center line.Two middle grooves are first groove 3, and two grooves of both sides are that the distance A B between 4, two first grooves 3 of second groove is 58.5cm, and the distance C D between two second grooves 4 is 74cm.First groove 3 and second groove 4 are applicable to the solar battery sheet of 125 and 156 liang of grid respectively.
During test, get a slice battery sheet finished product, do the tin bar of burn-oning on the electrode of test at needs, the battery sheet is placed the said fixing device, cover cover plate 1, the tin bar on the electrode exposes from corresponding groove, getting final product according to the corresponding test method test with tensiometer.
