Description

Technical Field

[0001] The invention relates to the technical field of battery welding ribbon welding, and in particular to a photovoltaic battery sheet tinned welding ribbon welding machine. Background Art

[0002] Photovoltaic cells are cells that convert sunlight into electricity. They are usually made of thin solid photovoltaic cells made of semiconductor materials (such as silicon). Simple photovoltaic cells can provide energy for watches and computers, while more complex photovoltaic systems can provide lighting for houses and power the grid. Photovoltaic cells are connected to tinned solder strips by welding to enable the battery to transmit current.

[0003] The invention with the publication number CN219562017U discloses an assembly welding device for photovoltaic equipment, which is started by a driving motor, and the driving turntable drives the workpiece to rotate appropriately, so as to facilitate welding of different areas of the workpiece and reposition the workpiece to be welded, so as to facilitate the continuous welding of the workpiece by the present invention, and improve the welding efficiency and effect of the workpiece;

[0004] The invention with publication number CN107855713A discloses a ribbon transfer welding system, which is provided with vacuum adsorption, which can effectively prevent the deviation of the battery cell during the transmission process. In addition, a preheating temperature control device is also provided on the conveying mechanism to preheat the battery cell to a certain temperature in advance, so as to improve the welding quality and welding efficiency; the first welding auxiliary pressure mechanism and the second welding auxiliary pressure mechanism can make the ribbon and the battery cell contact reliably, thereby ensuring the welding quality;

[0005] However, the above-mentioned welding ribbon welding machine for photovoltaic cells still has the following problems during actual use: the existing welding machine drives the battery to be moved and transported through a transfer mechanism so that the welding machine can perform the welding work, but such a transfer mechanism does not have a corresponding positioning and locking mechanism, and thus the battery is prone to displacement and misalignment during the transfer process, which in turn causes the welding of the welding ribbon to become desoldered. At the same time, the batteries of such welding machines need to be loaded by manual handling, resulting in low welding efficiency and the inability to ensure the stability of the welding of the welding ribbon.

[0006] Therefore, we propose a photovoltaic cell tinning ribbon welding machine to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide a photovoltaic cell tin-plated solder strip welding machine, in order to solve the problem that the existing welding machine drives the battery to be moved and transmitted by a transfer mechanism so that the welding machine can perform the welding work, but such a transfer mechanism does not have a corresponding positioning and locking mechanism, and thus the battery is easily offset and misaligned during the transfer process, which leads to the welding of the solder strip and desoldering.

The specific contents are as follows:

[0022] 1. The conveying shaft drives the transmission shaft and the incomplete gear to rotate through the first bevel gear, so that when the transmission shaft and the incomplete gear are meshed with the driving gear, the first sprocket mechanism drives the feeding mechanism to work, and the feeding turntable included in the feeding mechanism is fixed for the battery limit through the transmission frame with equal angles distributed on the top surface, and the incomplete gear is intermittently meshed with the driving gear, so that the feeding turntable drives the battery to rotate intermittently, so as to reserve time for loading and unloading the battery;
