Description

Technical Field

[0001] The utility model relates to the technical field of clamping mechanisms, and in particular to an electric welding strip clamping mechanism and a string welding machine. Background Art

[0002] The photovoltaic cell string welding machine is one of the core equipment in the production of photovoltaic modules. Welding the cells into cell strings is the core process of the equipment. After the cells are arranged, the electric welding ribbon clamping mechanism clamps the multiple welding ribbons on the welding ribbon unwinding device, pulls the welding ribbon to the welding platform, and accurately arranges the welding ribbon on the grid line of the cell. The welding ribbon is heated by the welding device to weld the welding ribbon and the cell together to form a cell string. Since the electric welding ribbon clamping mechanism needs to open and close frequently, clamping or releasing multiple welding ribbons at the same time, whether the welding ribbon is accurately arranged on the grid line of the cell directly affects the welding effect of the cell string. Therefore, it is necessary to clamp the welding ribbon during the traction and laying process to prevent the welding ribbon from being clamped off or falling off, and reduce welding exposure and abnormal machine shutdown. At present, the electric welding ribbon clamping mechanism of the string welding machine on the market generally uses a cylinder drive to control the opening and closing of the clamping jaws.

[0003] Publication No. CN118123885B provides an electric welding ribbon clamping mechanism and a string welding machine, the electric welding ribbon clamping mechanism includes a support assembly; a telescopic cylinder arranged on the support assembly; a transmission assembly movably arranged on the support assembly and transmission connected to the telescopic cylinder; a clamping claw assembly movably arranged on the support assembly and transmission connected to the transmission assembly; the transmission assembly includes a push rod; a pushing needle roller bearing and a pulling needle roller bearing movably arranged on the push rod respectively; a transmission pendulum block movably arranged in the support assembly; and a lever cam fixedly connected to the transmission pendulum block and passing through the support assembly and transmission connected to the clamping claw assembly. This technical solution adopts a cylinder drive method. The cylinder needs to perform frequent reversing to control the opening and closing of the clamping jaws. Vibration is likely to occur during the opening and closing interaction. The vibration may affect the placement of the welding strip on the battery cell, and there is a risk of white welding. In addition, the cylinder is easily affected by the gas source pressure. The gas source pressure may fluctuate due to the gas consumption in other places, causing the clamping force on the welding strip to be in a variable state, which is not conducive to the clamping control of the welding strip. If an electric proportional valve is added to control the cylinder, the cost of the structure will increase. Therefore, an electric welding strip clamping mechanism and a string welding machine are provided to solve the above problems. Utility Model Content
