Description
Technical Field
The invention relates to the technical field of photovoltaic production equipment, in particular to a high-precision clamping jaw device for carrying a photovoltaic welding strip and a using method thereof.
Background
The earth is the only home where the human beings rely on to live, and the human beings need to accelerate to form a green development mode and a life mode, build an ecological civilization and beautiful earth and deal with climate change. Paris agreement represents the great direction of global green low-carbon transformation, and is the minimum action required for protecting the earth home, so China will improve the autonomous contribution of the country, adopt more powerful policies and measures, strive for the carbon dioxide emission to reach the peak value 2030 years ago, strive for the carbon neutralization 2060 years ago. In order to realize the aim of carbon neutralization of the carbon peak reaching box at an early stage, 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 also faces vigorous development, and many technologies are changed subversively. The TOPCON battery and the heterojunction battery (HJT) become wind vane for the development of the photovoltaic industry due to the characteristics of higher efficient battery conversion efficiency and low attenuation, compared with the conventional battery, although the TOPCON battery and the heterojunction battery (HJT) have outstanding advantages, the manufacturing cost of a battery piece is relatively higher and becomes the main resistance for the development of the battery piece, so that the manufacturing cost of the battery piece is important for adapting to the rapid development requirement of the photovoltaic industry, the slurry accounts for about 24% in the manufacturing cost of the battery piece and is only secondary to a silicon wafer, the consumption of silver paste of the battery piece is important in the process of reducing the cost, and the consumption of the silver paste can be reduced by requiring the printing of the main grid of the battery piece to be thinner along with the increasing number of the main grids of the battery piece. 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 photovoltaic welding strip is about 0.30mm at present, the precision of the device is higher and higher, the device needs to accurately grab, carry and place the welding strip on a welding platform, the battery piece is placed above the welding strip through a visual positioning robot, the required deviation of the contact ratio between the center of the welding strip and the center of the main grid of the battery piece 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 volume production.
The battery piece mainly has two kinds with putting of welding the area on the existing market: the first mode is that the module puts the cut welding strip on a belt or a reciprocating jig through a welding strip groove along the welding strip direction, then puts a battery plate at a fixed point and presses the welding strip, the belt or the jig is stepped forwards, and the welding strip and the battery plate are put in a circulating manner; the second mode is that the welding strip is cut, the welding strip is placed on a welding table jig through a positioning claw, the battery pieces are placed at fixed points, the welding strip and the battery pieces are sequentially and forwards stepped, the welding strip and the battery pieces are placed in a recycling mode until one string is full, the welding strip and the battery pieces are stopped being placed, and after welding and blanking of one string are completed, the welding strip and the battery pieces are placed in the next string again. The claw mode of colluding of second kind need collude claw and welding stage tool cooperation, colludes claw and welding stage tool moreover and all must have the constant head tank, just can realize welding the accurate of taking and battery piece and putting. The first mode has a simple structure, but has poor precision, and mainly lies in that the welding strip is not positioned or the positioning groove is too wide in the process of placing the welding strip on the belt, so that the welding strip cannot be accurately positioned, and the welding strip is not positioned when falling off from the clamping jaw of the wire pulling module, so that deviation can be caused; in the process that the belt or the jig is stepped forwards, because the welding strip is not positioned, although the battery piece is pressed, the battery piece can slide relatively to cause large deviation, and further false welding can be caused, the first mode is only suitable for conventional battery pieces with wider main grids, and the welding strip can be lapped to form effective welding even if the welding strip deviates 0.5-1mm, and is not suitable for thin main grid battery pieces; the second mode is that the hook claw and the welding table of the welding strip are provided with a positioning groove, so that fixed-point high-precision conveying and placing of the welding strip can be realized, but the high-precision requirement needs the high precision requirement of matching the hook claw and the welding table jig, the welding table jig needs to be grooved to avoid the hook claw, the thickness of the welding table jig has strict requirement, the positions of the groove and the welding strip are fixed, and the position of the hook claw for clamping the welding strip is also fixed, so that great difficulty is increased in the process of debugging equipment, the taking and placing of the welding strip needs one more hook-in and hook-out action of a module, the time of a beat can be increased in the action, and the next string can be carried out only by completing the whole action of single string of placing, welding and blanking, so that the time of the next string is a reciprocating action, the productivity of a single rail is very long, and is only 50% of the productivity of a conventional single belt device, and only reciprocating rails can be increased if the productivity is desired, but the volume of the equipment is larger and larger, which brings great difficulty to processing, assembling and debugging; therefore, in a comprehensive view, the second mode is high in precision, but is large in limitation, the hook claw and the welding table jig must be accurately matched, the hook claw and the welding table jig can only be used in a reciprocating structure and cannot be used in a circulating structure, the debugging difficulty is high, the productivity is low, and the equipment is very complex.
