Elastic press mechanism applied to photovoltaic batteries soldered in series

Abstract

The invention discloses an elastic press mechanism applied to photovoltaic batteries soldered in series. The elastic press mechanism is characterized in that when entering a soldering zone, a battery piece is pressed by a press device (1), the elastic press mechanism (4) presses downwards, and is propped against four press blocks until metal wires (5) on the elastic press mechanism (4) presses the battery piece; when the soldering is completed, the press device (1) is lifted, the elastic press mechanism (4) is lifted automatically under the elastic force of a spring support frame (6); the elastic press mechanism (4) is composed of a fixing frame, a locking spring (3) and a plurality of metal wires (5) in parallel; a battery piece soldering strip is pressed by the metal wires (5) when the elastic press mechanism (4) presses; a majority of a pressing force is buffered by the elastic force of the locking spring (5) after the metal wires (5) are in contact with the battery piece.

Description

technical field [0001] The invention relates to an elastic compression mechanism applied to photovoltaic cell string welding, specifically, the device adopts a method in which multiple groups of metal wires form a certain angle to press the welding strips, which makes up for the current market. Defects of cells with different specifications, the device is suitable for cells with two grid lines, three grid lines and multi-grid cells with different areas and thicknesses, and is suitable for all cells with different busbar intervals. In the process of replacing batteries with different specifications, there is no need to make any adjustments to the device, and it can be used immediately after replacement, which greatly saves production time and greatly promotes the improvement of the overall production efficiency of the stringer. Background technique [0002] At present, most of the ribbon bonding devices of stringers on the market adopt the vertical bonding ribbon method, such...
