Abstract

The invention discloses a draw plate light shading device of an EL (Electroluminescent) tester, comprising the EL tester, an assembly bracket, a sliding light shading plate and a sliding guide rail, wherein the sliding guide rail is fixed at the upper end of the EL tester and the front side edge and the back side edge of the assembly bracket, the sliding light shading plate is matched with a rolling body of the sliding guide rail in a sliding mode, and the length of the sliding guide rail is a little larger than twice width of the assembly bracket. Because a roller shutter type light shading device of the traditional EL tester is changed into a sliding type light shading plate structure, the sliding light shading plate can portably slide on the sliding guide rail, can satisfy the light shading requirement of a detection process and can also be independently operated by only one person, therefore, the invention has the advantages of portable operation, rapid speed, long service life and low use cost consumption.

Description

The arm-tie shade of EL tester

Technical field

The present invention relates to the photovoltaic module test and use device, relate in particular to the shade of laminate EL testing apparatus.

Background technology

The main production run of solar module is to sort transparent glass, EVA, solar battery sheet, EVA and this different materials of backboard TPT stacked successively from the top down, form the laminate of solar components then through lamination, hot setting and process for cooling, the aluminium frame is installed at last again to improve its firm degree and to make it be easy to install around it, at last lead is drawn, promptly finished the making of solar components.People are called laminate with the semi-manufacture after the laminating machine laminating, before framing up usually.The fracture of battery sheet or recessive fracture all can cause battery to open circuit in the laminate, this fault can influence the life-span of assembly, the encapsulation process of solar components is generally used " two-step approach ", be lamination and curing two procedures, lamination is that fusion at high temperature takes place EVA, but the proterties of itself does not change, and degree of crosslinking is 0; Curing is that cross-linking reaction at high temperature takes place EVA, form tridimensional network, therefore, must check once more laminate before after lamination, solidifying, thereby find the battery component that has defective, be commonly called as " problem component ", prevent that " problem component " flows into the curing and the packaging process in road, back, guarantees the performance index of solar module.

In manufacture of solar cells enterprise, advanced manufacturing enterprise all has been equipped with battery component defect test instrument, at present, state-of-the-art equipment is the EL tester, EL (electroluminescence) is meant the electroluminescence principle, EL battery component defect test instrument is developed according to the electroluminescence principle of solar cell, and it is the instrumentation that is used for solar module inherent vice fast detecting, and people are simply referred to as the EL tester.After battery laminate is put into the test position of EL tester, feed and battery laminate short-circuit current electric current of a size in battery laminate, will have electric current to pass through in the battery sheet, silicon semiconductor sends near infrared light.The battery tablet quality is better, the higher light that then sends of efficient is brighter, otherwise it is then darker, so clearly illustrate sliver, poor efficiency sheet and the bad defective of other quality in the assembly according to the difference of battery sheet luminosity in the solar module, can monitor production technology, stop " problem component " and come into the market.When test, test zone need be covered up to prevent the influence of ambient light to test result, at present, the roller shutter type shade 11 that the EL tester is equipped with is shading door curtains made of cloth that similar volume is put curtain, as shown in Figure 1, because the axial length of the shading door curtain made of cloth is bigger, gobo must be by two people's synchro control when launching with rolling, if action is asynchronous, will draw partially, thereby influence shaded effect, the door curtain made of cloth of shading is simultaneously packed up or draws back frayed easily in frequent test process, and service time is not long, the not good test result that influences of damaged back shaded effect.

Summary of the invention

In order to overcome the above-mentioned shortcoming that existing EL tester shade exists, the invention provides a kind of arm-tie shade of EL tester.Adopt this shade, can not only satisfy the shading requirement of testing process, and as long as one just can independent operation, operate lightly, speed is fast, long service life, the use cost consumption of shade is low.

The technical solution adopted in the present invention is:

The arm-tie shade of described EL tester, it is characterized in that: it comprises the EL tester, assembly support, slip shadow shield and rail plate, described rail plate is fixed on the upper end of EL tester, and be positioned on the front side edge and back side edge of assembly support, on the dual-side of the front and back of slip shadow shield, be provided with the chute that cooperates with rail plate, with the part that the slip shadow shield contacts rolling body has been installed at rail plate, be fixed with extension rod at the right-hand member end face of EL tester and the drop section between the assembly support, described rail plate is fixed on the upper surface of assembly support and extension rod, and the length of rail plate is slightly larger than the twice of the width of assembly support.

Owing to will have the roller shutter type shade on the EL tester now, change slip shadow shield structure into, and slip shadow shield and rail plate roll by rolling body and are slidingly matched, the slip shadow shield can slide on rail plate easily, when the slip shadow shield covers assembly support, can carry out shading to testing component, the rigid structure of slip shadow shield and mechanical rolling slide construction have been guaranteed its operation portability and one man operation, can not only satisfy the shading requirement of testing process, and as long as one just can independent operation, operate lightly, speed is fast, long service life, the use cost of shade consumes low.

Embodiment

Below in conjunction with description of drawings the specific embodiment of the present invention:

The arm-tie shade of described EL tester, shown in Fig. 2～5, it comprises EL tester 1, assembly support 2, slip shadow shield 3 and rail plate 4, described rail plate 4 is fixed on the upper end of EL tester 1, and be positioned on the front side edge 5 and back side edge 6 of assembly support 2, on the dual-side of the front and back of slip shadow shield 3, be provided with the chute 7 that cooperates with rail plate 4, in the part that rail plate 4 contacts with slip shadow shield 3 rolling body 8 has been installed, be fixed with extension rod 9 at the right-hand member end face of EL tester 1 and the drop section between the assembly support 2, described rail plate 4 is fixed on the upper surface of assembly support 2 and extension rod 9, and the length of rail plate 4 is slightly larger than the twice of the width of assembly support 2.
