Problems solved by technology

[0003] Even if the traditional stringer equipment can meet MBB technology stacking half-cell modules after transformation, the production capacity will be halved because the cells are cut in half, and the total number of cells is doubled; at the same time, the number of small strings is also doubled, and the layout of photovoltaic modules is also more. A lot of changes have been made, and in order to improve the yield rate of components, it is necessary to pick out various defective products in the small string
There is not enough space on the original typesetting machine to realize various inspection functions (such as cell PL detection, small string white appearance detection and EL detection); at the same time, it cannot meet the demand for production capacity as the number of small strings increases; re-design photovoltaic modules and typesetting The equipment is optimized for the process and forms an integrated equipment, which is more suitable for the needs of the new process

specific Embodiment 1

[0111] Only one welding belt is arranged on the welding support frame.

[0112] The head of the welding support frame is fixedly provided with a ribbon guide plate 68, and the ribbon guide plate is provided with a ribbon guide groove 69, and the groove width X of the ribbon guide groove is set to be slightly larger than the width x′ of the ribbon , the thickness Y of the ribbon guiding groove is set to be slightly larger than the thickness y′ of the ribbon. When the battery string is transported on the welding belt, the ribbon below the battery slice will be located in the ribbon guide groove of the ribbon guide plate, which can prevent the ribbon from shifting, and the ribbon guide groove can ensure that the ribbon on the battery string is opposite to the battery slice The position accuracy is high, in which, the ribbon guide plate remains fixed during the welding belt transmission process, and the guide groove does not need to be transmitted along with the battery string.

specific Embodiment 2

[0115] A plurality of welding belts are arranged on the welding support frame.

[0116] At this time, the distance x (ie gap width x) between two adjacent welding belts is slightly larger than the width x′ of the welding belt, and the thickness y of each welding belt is slightly larger than the thickness y′ of the welding belt. When the battery string is transported on the welding belt, the welding ribbon under the battery sheet will always be located in the gap 612 between the two welding belts, which can prevent the welding ribbon from shifting.

[0117] A plurality of ribbon guide grooves corresponding to the gaps between the welding belts can also be provided on the vacuum adsorption plate, so that the ribbons under the cells are located in the ribbon guide grooves and gaps, further preventing the ribbons from shifting.

[0118] In order to further guide and correct the welding strip, the head of the welding support frame is fixedly provided with a welding strip guiding pl...

specific Embodiment 3

[0120] Only one welding belt is arranged on the welding support frame.

[0121] The head of the welding support frame is fixedly provided with a ribbon guide plate, and a ribbon guide groove is arranged on the ribbon guide plate. In addition, a ribbon guide groove is also arranged on the welding belt itself or on the welding belt and the vacuum adsorption plate. Groove, the ribbon guide groove on the welding belt corresponds to the ribbon guide groove on the ribbon guide plate, the weld belt corresponds to the ribbon guide groove on the vacuum adsorption plate, and the ribbon guide groove on the ribbon guide plate The leading end of the ribbon guide groove is connected with an introduction groove.

[0122] Wherein, the groove width X of the ribbon guide groove is set to be slightly larger than the width x' of the solder ribbon, and the thickness Y of the ribbon guide groove is set to be slightly larger than the thickness y' of the solder ribbon. When the battery string is tra...

Abstract

The invention discloses photovoltaic module series welding and typesetting integrated production equipment which comprises a feeding, scribing, cracking and carrying device, a high-temperature weldingand curing device and a small battery string typesetting mechanism. The feeding, scribing, cracking and carrying device is used for feeding, scribing and cracking battery pieces to form small batterypieces; the equipment comprises a battery piece feeding mechanism, a battery piece carrying and scribing mechanism, a battery piece splitting mechanism and a manipulator piece grabbing mechanism. Bymeans of the mode, the photovoltaic module series welding and typesetting integrated production equipment is compatible with various battery piece specifications, multi-grid-line patterns and variousmodule typesetting patterns, meets various technologies such as stitch welding and the like for reducing the distance between pieces, and achieves cell piece scribing, series welding and typesetting from an integrated machine; and the large-piece productivity of the equipment is improved, the small-string yield is improved, the yield of the whole battery assembly is improved, and the manual repairrate is reduced.

Description

technical field [0001] The invention relates to the field of photovoltaic module production equipment, in particular to a photovoltaic module serial welding and layout integrated production equipment. Background technique [0002] With the more and more widespread application of solar power generation, the demand for photovoltaic modules is increasing, and MBB multi-busbar, close-packing and other technologies are widely used. At present, the existing equipment can no longer adapt to the increasingly changeable MBB technology, various Stringing technology to improve the efficiency of photovoltaic modules, and the need for high-speed production. Traditional photovoltaic modules are welded in large pieces, and the number of grid lines is less than 6 grids. At present, MBB technology stacks half-chip modules, which has obvious benefits in improving the efficiency of modules, and has gradually become the mainstream of the market. [0003] Even if the traditional stringer equipm...
