Description

Bus bar welding floating backing plate device

Technical Field

The utility model relates to a busbar welding technical field specifically is a busbar welding backing plate device that floats.

Background

Solar energy is a renewable clean energy source, and the solar energy is utilized to generate electricity, which is increasingly paid attention and favored by people. A solar cell module is a power generation device that converts light energy into electric energy. In the manufacturing process of the solar cell module, a plurality of solar cells for collecting heat are required to be connected and welded into a cell string, the welded cell string is laid on glass sheets side by side, then the plurality of cell strings are connected into a complete circuit through bus bars, and finally the solar cell module is manufactured.

The operation of reconnecting the plurality of battery strings by the bus bar is generally performed on a pallet device. For guaranteeing to weld on busbar and the battery cluster and take the connection quality, generally all be provided with the vacuum adsorption hole that adsorbs the busbar on the backing plate and carry out spacing recess to the busbar, rethread heating device welds busbar and solder strip, but through a large amount of experiments verification, after busbar and solder strip welding, because of vacuum adsorption power and influence of being heated, can leave on the busbar and adsorb the impression and the busbar is connected inseparably or the condition that the solder joint impression is not different with the solder strip depth, influence whole pleasing to the eye and welding quality.

Meanwhile, the experiment finds that: during welding, the flatness requirements on the heating device and the backing plate device are high, the heating device and the backing plate device are not well attached, and cold joint is easy to generate. In addition, certain pressure is needed, and due to the fact that the pressure is too low, cold joint is easy to occur, and product quality is affected. At present, the heating device is mainly adjusted repeatedly to meet the requirement of the two on bonding, the work content is complicated, and the technical requirement on workers is high.

SUMMERY OF THE UTILITY MODEL

Objects of the invention

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-3, the utility model provides a busbar welding floating backing plate device, including bottom plate 1, welding backing plate 2, slider 3, bottom plate 1 and welding backing plate 2 fixed connection, be equipped with a plurality of notches 4 on the welding backing plate 2, slider 3 locates between bottom plate 1 and the welding backing plate 2 and corresponding with notch 4 position.

In a specific embodiment, the floating block 3 includes a vacuum block 31, a spring 32, and an air passage port 33, the vacuum block 31 has a hollow structure with a cylindrical inner cavity, and is in threaded connection with the air passage port 33, one end of the spring 32 is fixed to the bottom of the vacuum block 31, and the other end is fixed to the bottom plate 1. The slider 3 is further provided with a protrusion which passes through the notch. The side of welding backing plate 2 is equipped with the opening that supplies slider 3 to install, be equipped with the bar hole on the bottom plate 1, the design in bar hole to when the mounting plate, the fine setting of position is convenient for.

The bottom plate 1 and the welding backing plate 2 can adopt a screw connection mode, the floating block 3 is limited by the notch 4 and can only move up and down along the notch 4, and the size of the lower side of the floating block 3 is larger than that of the notch, so the floating block 3 can only move a limited distance along the notch 4 and can not be separated from the notch 4.

It should be noted that, gas is injected into the cylindrical cavity through the gas path interface 33 (i.e., gas is injected into the vacuum block 31), and the cavity can generate a vacuum cavity by using a vacuum generator to absorb and convey the bus bar.
