Opening device for electrode insulation shunting strips of solar cell module

Abstract

An opening device for electrode insulation shunting strips of a solar cell module comprises a hand press, a clamp body, an insulation strip moving and fixing frame, an opening template, a tool clamping device and an opening blade. The insulation strip moving and fixing frame is placed on the clamp body, electrode shunting insulation strips are stacked in the insulation strip moving and fixing frame, and are subject to press fit through the opening template, the tool clamping device is fixedly mounted on a telescopic rod of the hand press, and the opening blade is mounted on the tool clamping device; a cutting edge is aligned with a tool setting groove, and when the insulation strip moving and fixing frame is located at the limit position, the opening blade is aligned with the opening positions of the electrode shunting insulation strips; mechanization of opening the electrode shunting insulation strips is achieved, manual opening errors are completely eradicated, opening accuracy is improved, mechanical opening production efficiency is high, and 15 to 25 strips can be cut at a time; and due to the device, workloads originally completed by three persons can be completed now within two hours, labor intensity is greatly reduced, and production safety hidden danger caused by manual opening pulling and scratching can be thoroughly eliminated.

Description

Technical field: [0001] The invention relates to special equipment for producing solar modules in the photovoltaic solar industry, in particular to an opening device for an electrode insulating shunt strip of a solar module. Background technique: [0002] The main production process of solar cell modules is to lay the qualified solar cell wafer strings with glass, EVA, glass fiber, and back sheets according to a certain level. backplane. When laying, the relative position requirements between the layers should be ensured, and the distance between the solar cell silicon wafer strings should be adjusted to lay a good foundation for lamination. Put the laid solar cell laminate into the laminator, pump out the air in the module by vacuuming, then heat to melt the EVA to bond the solar cell, glass and back sheet together, and finally cool and take out the module. In the production process of solar cell modules, if the cells in the module have defects such as breakage or hidden ...

Problems solved by technology

In the production process of solar cell modules, if there are defects such as fractures or hidden fractures in the cells of the components, it will cause the battery to be disconnected or affect the service life of the components.

Among them, the battery silicon string is composed of positive and negative battery slices connected in series and in parallel. In the solar cell module, it is located in the backplane and located at the installation of the junction box. It must be used for electrode shunt insulation pads. It is used to separate the positive and negative electrodes of the solar cell module to prevent the short circuit of the positive and negative electrodes of the battery module. Whether the cutting position of the electrode lead opening of the electrode shunt insulating strip is accurate will not only directly affect whether the electrode leads of the battery module can be successfully drawn out and insulated, but also Affect the assembly progress of the entire assembly line

[0003] The openings of the electrode leads of the existing electrode branch insulating strips are artificially opened. The operator spreads 2 to 3 electrode branch insulating strips to be opened on the workbench, and uses an opening template to place them on the electrode branch insulating strips. , the lower knife notch is pre-set on the opening template, and the operator holds a single-sided blade along the lower knife notch to draw the opening forcefully. Since the material of the electrode shunt insulating strip is EVA, the operator must use even force when drawing the opening manually. Steady, too much force will cause the blade to break, and the opening of the electrode shunt insulating strip will be scrapped, and the operator’s hand will be scratched and injured if the force is too light; the opening of the electrode shunt insulating strip is not complete, and it still cannot reach Opening requirements, the production efficiency of this kind of manual opening is very low. According to the existing production rhythm, this process must be equipped with 3 opening workers to meet the requirements. Manual opening is time-consuming and laborious, the production efficiency is low, the opening quality is difficult to guarantee, and production safety exists. Hidden danger
