Ultrasonic roll welding stand

Abstract

The invention relates to an ultrasonic roll welding stand which comprises a platform, a bearing arm, an ultrasonic roll welding device and a metal band supply device, wherein the platform is rectangular, the short axis of the platform is parallel with the X axis, and the long axis of the platform is parallel with the Y axis; the bearing arm is parallel with the Y axis and has a preset distance to the platform; the ultrasonic roll welding device is arranged on the bearing arm near the front end of the platform, and the ultrasonic roll welding device is provided with a lifting unit and a disc type ultrasonic welding head; and the metal band supply device can supply a metal band to the disc type ultrasonic welding head, the metal band supply device is provided with a spacing groove, the spacing groove is arranged at the back end of the disc type ultrasonic welding head, the metal band is arranged in the spacing groove, and the front section of the metal band protrudes out of the spacing groove and is clamped between the disc type ultrasonic welding head and the platform. Thus, the metal band can be quickly welded onto one substrate without deviation to be used for improving the processing quality and increasing the product yield.

Description

technical field [0001] The present invention is related to welding technology, in particular to an ultrasonic seam welding machine. Background technique [0002] In solar cells, the power supply of a single solar panel is not enough to supply the load voltage of the application appliances or batteries. Therefore, the current technology is to solve the problem of power supply by means of series and parallel connections. [0003] Therefore, general thin-film solar cells are connected in series through several solar substrates to achieve the voltage required by various electrical appliances or batteries. Conductive metal strips on the solar substrate to achieve the effect of series voltage. [0004] From the above, it can be seen that welding conductive metal strips on the solar substrate is necessary for the solar substrates to be connected in series or in parallel. There are problems such as lead wires and welding points that are easy to break or fall off, and when the meta...

Problems solved by technology

[0004] From the above, it can be seen that welding conductive metal strips on the solar substrate is necessary for the solar substrates to be connected in series or in parallel. There are problems such as lead wires and welding points that are easy to break or fall off, and when the metal strip is welded on the substrate, it is not only time-consuming and laborious, but also after the metal strip is welded on the substrate, the surface of the substrate is uneven or the metal strip is skewed. Due to the above phenomenon, the solar substrates are disconnected in series, or the voltage after parallel connection is insufficient, so there are disadvantages such as reducing the yield of solar cells and increasing operating costs.

[0005] To sum up, the existing solar panel welding methods have major deficiencies and need to be improved
