The sustainable green energy is urgently developed, clean energy represented by wind power, photoelectricity and hydropower becomes the main force of energy conservation and emission reduction, particularly, the photoelectricity is the main force, the technical route is relatively simple, the advantages of being free from regional limitation and wide in application are widely accepted by various industries, and therefore the photovoltaic industry is also confronted with the vigorous development, and a plurality of technologies are subversively changed. In the wave photovoltaic leather, TOPCON cells and heterojunction cells (HJT) become wind vanes for the development of the photovoltaic industry due to the characteristics of higher efficient cell conversion efficiency and low attenuation, and compared with conventional cells, although the TOPCON cells and the heterojunction cells (HJT) have outstanding advantages, the manufacturing cost of the cells is relatively higher and becomes the main resistance of the development, so that the manufacturing cost of the cells is important for adapting to the rapid development needs of the photovoltaic industry, the slurry accounts for about 24% in the manufacturing cost of the cells and is inferior to silicon wafers, the consumption of silver paste of the cells is important in the process of reducing the cost, and as the number of main grids of the cells is more and more, the consumption of the silver paste can be reduced by requiring the printing of the main grids of the cells to be thinner. The photovoltaic module is manufactured by firstly paving welding strips on front and back main grids of battery pieces, connecting positive and negative electrodes between the battery pieces by the welding strips, paving a plurality of battery pieces into a string, welding the battery pieces into a string of battery strings, connecting the positive and negative electrodes of the battery strings in series to form a module, and packaging the module to form a module finished product on the market. The photovoltaic series welding machine is a device for connecting the positive electrode and the negative electrode of a battery piece in series, the photovoltaic welding strip is thinner and thinner along with the fact that the main grid of the battery piece is thinner and thinner, the diameter of the current photovoltaic welding strip is about 0.30mm, the device is required to be higher and higher in precision, the device needs to accurately grab, carry and place the welding strip on a welding table, the battery piece is placed above the welding strip through a visual positioning robot, the contact ratio of the center of the welding strip and the center of the main grid of the battery piece is required to be different and cannot exceed 0.05mm, otherwise, the welding strip deviates from the main grid silver paste of the battery piece to cause false welding, the yield of the produced battery string is too low, and the photovoltaic series welding machine is not suitable for mass production. The battery piece and the solder strip are placed on the market at present, the solder strip is hooked through the hook claw, then the battery piece and the solder strip are carried to a target position, the hook claw needs to hook the solder strip from the lower part of the solder strip, the placing place needs to be designed with a hook groove for hooking, and interference between the hook claw and a soldering table or a jig for placing the solder strip is avoided. The processing cost is increased in design, the grabbing and placing actions of the hook claws are to extend to the placing position and then retract to the grabbing position, the whole action can be completed only by single-string placing, welding and blanking, the next string can be carried out, and the productivity is low.
