Problems solved by technology

In order to effectively use this part of the light, a heating body with a high-reflection film paste module has appeared in the industry. After the battery unit is welded, the temperature is higher at this time, and the reflective film is pasted on the surface of the interconnection strip, so as to reduce the reflection from the glass. However, this technology increases the cost of materials, and there will be more defective products that need to be repaired, which increases the cost of man-hours, and the reflective film has a certain thickness. The thickness of the interconnection strips increases, and the temperature may change alternately during the weather resistance test. The risk of cracks at the interconnection strips of the battery cells is mentioned, thereby reducing the physical properties of the components; therefore, this technology is not widely used. application to solar module production

Embodiment 1

[0024] Such as Figure 1 to Figure 6 As shown, the solar panel interconnection strip integrated straight rod processing device of the present invention, the solar panel interconnection strip integrated straight rod processing device includes a heating body 1 for welding the solar panel 4 interconnection strips 3, and also includes embossing Straight rod, heat conduction guide rod, heat conduction inlet pipe and heat conduction outlet pipe, one end of the embossed straight rod is connected to the heating body 1 through the heat conduction guide rod and arranged in parallel directly above the interconnecting bar 3, the embossed straight rod is together with the heating body 1 Moving up and down, the heat-conducting guide rod is a movable connecting rod or a fixed connecting rod; the side of the embossed straight rod opposite to the interconnecting bar 3 is provided with a pattern structure; the other end of the embossed straight rod is cooled by a heat-conducting inlet pipe and a...

Embodiment 2

[0027] This embodiment describes the principles to be protected from the perspective of solving problems of the present invention.

[0028] The first problem to be solved in the present invention is: besides the solar battery panel 4, the power generation of the solar battery panel 4 can be improved from other angles. Through detailed research, it is found that the interconnection bar 3 itself is very smooth when the heating body 1 is welded to the surface of the solar cell, and the light passes through the glass and is incident on the interconnection bar 3, where mirror reflection occurs, and the reflection angle is smaller than the glass refraction angle. It will pass through the glass and enter the air, and this part of the light has not been reasonably utilized for power generation by the components. In order to realize the diffuse reflection of the interconnection bar 3 , the prior art adopts a reflective film pasted on the surface of the interconnection bar 3 . It does ...

Embodiment 3

[0035] In the second embodiment above, it is explained that the function of the heat conduction guide rod is to not only perform the function of heat conduction, but also perform the function of connection. This embodiment further describes the heat-conducting guide rod. The heat conduction guide rod is a movable connecting rod or a fixed connecting rod. Since the straight rod processing device 2 only needs to be connected with the heating body 1, it is uncertain whether the heat conduction guide rod and the heating body 1 are fixedly connected, and it does not necessarily have to be fixedly connected. The downforce can be controlled according to the needs of the pressed interconnecting bars 3 through the movable connecting rod, and patterns of different depths can be pressed. Therefore, the heat conducting guide bar can be both fixed and movable. In addition, common connection methods such as bolt connection can be used for the connection method between the heat conduction ...

Abstract

The invention relates to a solar-cell-panel interconnection-strip integrated straight rod processing apparatus and belongs to the welding machine module technology field. A problem that an existing interconnection strip can not solve diffuse reflection from a source is solved. The apparatus comprises a heating body welding a solar cell panel interconnection strip, a knurling straight rod, a heat conduction guide rod, a heat conduction inlet pipe and a heat conduction outlet pipe. One end of the knurling straight rod is connected to the heating body through the heat conduction guide rod and is arranged right above the interconnection strip in a parallel mode. The knurling straight rod moves up and down along with the heating body. The heat conduction guide rod is a movable connecting rod or a fixing connecting rod. One surface of the knurling straight rod, which is opposite to the interconnection strip, is provided with a patterned structure. The other end of the knurling straight rod is cooled through the heat conduction inlet pipe and the heat conduction outlet pipe. By using the straight rod processing apparatus, through suppressing the interconnection strip, diffuse reflection stripes are formed; the apparatus possesses a good market application value; and a generating capacity of the processed solar cell panel is increased by 1.5 percent points.

Description

technical field [0001] The invention relates to an integrated straight rod processing device for interconnecting strips of solar panels, and belongs to the technical field of welding machine modules. Background technique [0002] For the traditional solar cell heating body, the welding method is to use laser / infrared / hot air / electromagnetic / welding head to weld the battery unit for a single module, and several unit batteries are welded to form a battery string, and then flow to the next process. [0003] For this type of solar cell module, when the unit cells are welded, the coating on the surface of the interconnection strip is melted at high temperature to form a smoother plane. When the battery unit is finally packaged into a component, the light passes through the glass and enters the interconnection strip. Specular reflection occurs, and the light whose reflection angle is smaller than the refraction angle of the glass will pass through the glass and enter the air. This...
