Background

With the rising of energy prices, the development and utilization of new energy is a major subject of research in the energy field today. Because solar energy has the advantages of no pollution, no regional limitation, inexhaustible energy and the like, the research on solar power generation becomes a main direction for developing and utilizing new energy. The generation of electricity by solar modules is a main mode of using solar energy by people at present, wherein solar cells are the main components of the solar modules.

In order to increase the output power of the solar cells, it is a common practice to connect a plurality of solar cells in series. Referring to fig. 22 and 23, in the prior art, a series connection method of solar cells is as follows: the solder strip feeding mechanism 9000 can provide a group of solder strips (conductor strips) which are parallel to each other, a plurality of grid strips 11 which are parallel to each other are arranged on the front and back surfaces of each battery piece 1, the front surface of one battery piece 1 is connected with the back surface of the adjacent battery piece 1 through the solder strips, each solder strip is correspondingly clamped in the grid strips 11 of the two battery pieces 1, the solder strips and the battery pieces 1 are continuously and alternately placed by automation equipment and are transmitted and welded to form a battery string 10 which is connected with each other, wherein the length extending direction of the solder strips, the length extending direction of the grid strips 11 and the extending direction of the battery string 10 are parallel to each other or coincide with each other.

From the above, the conventional method for feeding the welding strips for series welding of the battery strings is to arrange a plurality of groups of welding strip feeding mechanisms in the direction parallel to the grid bars of the battery pieces, and to meet the requirement of multiple parallel welding (simultaneous welding of a plurality of battery strings), the number of groups of welding strip feeding mechanisms can be greatly increased. For example, for m parallel cell welding, if there are n grid bars on each cell, m sets of solder ribbon feeding mechanisms are required, and each set of solder ribbon feeding mechanism needs to have n rotating shafts. As the number of parallel battery pieces or the number of grids increases, the total number m of the solder strip feeding mechanisms is greatly increased.

In the method, the cell sheet above the cell sheet needs to be lifted up in the process of welding a plurality of small cell strings, so that the complexity and difficulty of the production process are increased undoubtedly, and the production and running cost of equipment is correspondingly increased.

In summary, most of the production equipment for solar cell strings in the prior art has one or more problems of low production efficiency, high production cost, large floor area, difficulty in use and maintenance and the like.

Specifically, the solder strip preparation apparatus 1000 includes a solder strip winding mechanism 1100, a tape pulling mechanism 1200, a cutting mechanism 1300, a clamping mechanism 1400, a rotating mechanism 1500, and a transfer mechanism.

Among them, the solder strip winding mechanism 1100 is provided on one side portion of the frame 8000 in the X direction, and supplies the solder strip 2, which is a raw material of the solder strip 211. The welding strip winding mechanism 1100 has n groups, each group of welding strip winding mechanisms 1100 has a rotatable rotating shaft, and n groups of welding strip materials 2 are correspondingly wound on the rotating shafts of the n groups of welding strip winding mechanisms 1100. The tape drawing mechanism 1200 is provided on the frame 8000 so as to be movable back and forth in the X ' direction, and the tape drawing mechanism 1200 can draw one end portions of the n sets of solder ribbon strips 2 at the same time, and draw out the n sets of solder ribbon strips 2 from the solder ribbon winding mechanism 1100 in the X ' direction at the same time, thereby obtaining n parallel solder ribbon strips 2 each extending in the X ' direction. Wherein, the X 'direction intersects with the Y direction, and in this embodiment, the X' direction is parallel to the X direction.

The cutting mechanism 1300 is configured to cut the solder strip 2, so that the solder strip 2 pulled out by the pulling strip mechanism 1200 is separated from the solder strip 2 wound on the solder strip winding mechanism 1100, the cut solder strip 2 is the original solder strip 21 extending along the X 'direction, and the original solder strip 21 is continuously cut to obtain a plurality of solder strips 211 extending along the X' direction. Specifically, the cutting mechanisms 1300 have (m + 1) sets arranged at intervals in the X ' direction, the two sets of cutting mechanisms 1300 located at the two end portions can simultaneously cut the n drawn-out solder strip tapes 2 to obtain n raw solder strips 21 extending in the X ' direction, and the cutting mechanism 1300 located in the middle can further divide each raw solder strip 21 into m solder strips 211, each solder strip 211 extending in the X ' direction. Cutting means include, but are not limited to, mechanical cutting, laser cutting, and the like.

Referring to fig. 11 and 14, as can be seen from the above, after cutting by the cutting mechanism 1300, m sets of solder strip sets 20 extending along the X 'direction can be obtained, each set of solder strip set 20 includes n solder strips 211 extending along the X' direction, in order to obtain m sets of solder strip sets 20 extending along the Y direction, the solder strip preparation apparatus 1000 is further provided with m sets of clamping mechanisms 1400 and m sets of rotating mechanisms 1500, which are in one-to-one correspondence, and a set of rotating mechanisms 1500 is connected above each set of clamping mechanisms 1400. Specifically, m groups of clamping mechanisms 1400 are arranged along the X' direction, each group of clamping mechanisms 1400 comprises n clamping units 3, each clamping unit 3 comprises two groups of clamping jaws 31 respectively arranged on two sides, each clamping mechanism 1400 further comprises a clamping cylinder 4 used for driving the two adjacent groups of clamping jaws 31 to move in opposite directions or in opposite directions, so that each clamping unit 3 can clamp two end portions of one welding strip 211, and each group of clamping mechanisms 1400 can simultaneously clamp all welding strips 211 parallel to each other in one group of welding strip groups 20, so that the positions of all welding strips 211 are relatively fixed and do not deviate from the corresponding positions, and the welding strips 211 can be kept in a tightened state. Therefore, the rotating mechanism 1500 can drive the clamping mechanism 1400 to rotate around the rotation center line P, the rotation center line P extends along the Z direction, and after rotating 90 degrees, the rotating mechanism 1500 enables the extending directions of all the solder strips 211 clamped by the clamping mechanism 1400 to rotate to the Y direction at the same time. In this embodiment, the m sets of rotation mechanisms 1500 are independent of each other and can rotate separately or simultaneously.

In addition, it should be noted that m groups of solder ribbon groups 20 extending along the Y direction obtained by cutting and rotating directly may not completely correspond to the positions of m battery pieces 1 arranged along the X direction, therefore, the solder ribbon preparation apparatus 1000 further comprises a transfer mechanism, which specifically comprises an X ' direction moving shaft 1600 extending along the X ' direction, a clamping mechanism 1400 is disposed below the rotating mechanism 1500, the rotating mechanism 1500 is connected to the X ' direction moving shaft 1600 through a mover and can slide along the X ' direction moving shaft 1600, so that before the rotating mechanism 1500 drives the clamping mechanism 1400 to rotate, the transfer mechanism can first drive each group of clamping mechanisms 1400 to slide to the position corresponding to the battery piece 1, so that the clamping mechanism 1400 can be directly matched with the battery piece 1 in the X ' direction after rotating, and each solder ribbon 211 can also correspond to the position of the grid 11 on the battery piece 1, the equipment is more convenient and reliable to operate. In addition, the transfer mechanism disperses the clamping mechanisms 1400 in the direction of the rotation front edge X, so that mutual interference of a plurality of clamping mechanisms 1400 in the rotation process can be avoided, and smooth operation of equipment is ensured.

It should be noted that in other embodiments, for example, in a scenario limited by factory space, the X' direction may not be parallel to the X direction. In this case, the solder ribbon preparation apparatus 1000 is further provided with a rotation mechanism for rotating the X '-direction moving shaft 1600 extending in the X' -direction to extend in the X-direction. Specifically, after m sets of solder strip sets 20 extending in the X ' direction are prepared, the rotating mechanism drives the X ' to integrally rotate toward the moving shaft 1600, so that all the clamping mechanisms 1400 connected to the X ' on the moving shaft 1600 also integrally rotate, the m sets of solder strip sets 20 are all converted into X-direction extensions, and the m sets of solder strip sets 20 are arranged in the X direction, and then the rotating mechanism 1500 can drive the clamping mechanisms 1400 to rotate, so that the m sets of solder strip sets 20 are all converted into Y-direction extensions.

In this embodiment, the X direction, the Y direction, and the Z direction are not coplanar, and the three directions are perpendicular to each other. The X '-direction moving shaft 1600, the Y-direction moving shaft 7100 and the Z-direction moving shaft 7200 are connected in pairs, so that the rotating mechanism 1500 and the clamping mechanism 1400 connected to the X' -direction moving shaft 1600 can reach each position in the spatial range spanned by the three moving shafts, and the accurate pairing of the solder strip group 20 and the battery piece 1 is realized.
