[0035] The embodiments of the present application provide a carrier, a processing device and a processing method, which solve the technical problems of complex structure of welding equipment and low welding efficiency, and achieve the technical effect of simplifying the welding structure and improving the welding efficiency.
[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.
[0037] In the field of photovoltaic cell production, a soldering tape 400 is usually required to be welded on the cell 300 to conduct the current generated by the silicon chip; generally, the soldering tape 400 uses a copper-tin soldering tape 400 or other soldering tape 400 with a tin coating, so that the soldering tape 400 can be welded on the cell 300 or other objects after heating. Since the metal soldering tape 400 has certain perturbations, the soldering tape 400 will be deformed to a certain extent after winding, and the soldering tape 400 cannot be restored to the initial straight state. Therefore, during the welding process, how to accurately and efficiently transfer the soldering tape 400 is a technical problem that needs to be solved urgently.
[0038] The present application provides a carrier for carrying a solder strip 400, such as Figure 1-4 As shown, specifically, the first carrier 100 provided in the present application is used to wind the welding ribbon 400, and the welding ribbon 400 is wound on the first carrier 100 for transfer. The first carrier 100, the first carrier 100 is used to carry the welding ribbon 400. The first carrier 100 includes a first carrier body 110 and a first driving component, the first carrier body 110 is used to wind the welding ribbon 400, and serves as the main body carrying the welding ribbon 400; the first driving component is used to drive the first carrier body 110 to rotate.
[0039] The first carrier body 110, such as Figure 1 As shown, the first carrier body 110 is used to wind the welding ribbon 400, and serves as the main body for carrying the welding ribbon 400. The first carrier 100 has a rotational freedom of rotation around an axis; specifically, the first carrier body 110 has a continuous rotating circumferential side surface, so that the first carrier body 110 cooperates with the wiring structure of the welding ribbon 400 to realize winding the welding ribbon 400 on the rotating circumferential side surface of the first carrier body 110, or removing the welding ribbon 400 on the rotating circumferential side surface of the first carrier body 110.
[0040] Further, such as Figure 2 As shown, a first zone 111 and a second zone 112 are provided on the rotating circumferential side surface of the first carrier body 110. The first zone 111 and the second zone 112 are relatively independently provided. The first zone 111 is provided along the axial direction of the first carrier body 110, or the arrangement direction of the first zone 111 is substantially parallel to the axial direction of the first carrier body 110. In other words, the first zone 111 is arranged along the axial direction of the first carrier body 110, and the first zone 111 is provided in a long strip shape. The second zone 112 refers to: a portion other than the first zone 111 on the circumferential side surface of the rotating shaft of the first carrier body 110.
[0041] It is worth noting that if Figure 2As shown, the first area 111 and the second area 112 are relatively independently arranged, which means that both the first area 111 and the second area 112 have adsorption functions, and the adsorption functions of the first area 111 and the second area 112 are relatively independent, wherein the first area 111 also has an air blowing function. In one embodiment, through holes 113 can be opened in the first area 111 and the second area 112, and air pumping structures can be externally connected to the through holes 113 of the first area 111 and the second area 112, respectively, and vacuum is formed in the through holes 113 of the first area 111 and the second area 112, so that the adsorption functions of the first area 111 and the second area 112 can be realized; further, the air pumping structure externally connected to the through holes 113 of the first area 111 also has an air blowing function, so that the first area 111 has both adsorption and air blowing functions. In this way, when the soldering ribbon 400 is wound around the rotating circumferential side surface of the first carrier body 110 , the matching piece 120 can be fixed by adsorption or pushed out by blowing through the through holes 113 on the first area 111 ; the soldering ribbon 400 can be fixed by adsorption through the through holes 113 on the second area 112 .
[0042] Furthermore, the first carrier 100 further includes a matching piece 120, and the matching piece 120 is used to stabilize the soldering ribbon 400 and to accurately transfer the soldering ribbon 400. Figure 2 , 3 4, the matching piece 120 is used to match with the first area 111. Specifically, the matching piece 120 is arranged on the first area 111 before the welding ribbon 400 is wound or during the welding ribbon 400 is wound. In other words, the matching piece 120 is fixed on the first area 111 by adsorption, and the welding ribbon 400 is wound on the rotating circumferential side of the first carrier body 110. After the welding ribbon 400 is wound, the matching piece 120 is in contact and connected with the welding ribbon 400, and the welding ribbon 400 is wound in a spiral shape, and a plurality of contact points are formed between the welding ribbon 400 and the matching piece 120. Preferably, at each contact point, the soldering tape 400 contacts and is connected to the mating piece 120; the soldering tape 400 and the mating piece 120 may be connected in a variety of ways. In one embodiment, a side of the mating piece 120 facing the soldering tape 400 is sticky, while a side of the mating piece 120 facing the first zone 111 is not sticky, thereby forming a connection between the mating piece 120 and the soldering tape 400; in other embodiments, the mating piece 120 may be welded to the soldering tape 400 by heating, thereby also achieving a connection between the mating piece 120 and the soldering tape 400.
[0043] It is understandable that if Figure 4As shown, the first area 111 and the matching piece 120 are adsorbed and matched. After the welding strip 400 is wound, the matching piece 120 and the welding strip 400 are connected. The welding strip 400 is cut along one side of the matching piece 120, so that the welding strip 400 is cut into a group of welding strips 400 as a whole. In this way, since the matching piece 120 is connected to the welding strip 400, one end of the welding strip group 410 is fixed by the matching piece 120. In one embodiment, the first area 111 and the matching piece 120 can have two groups. On the rotating peripheral side of the first carrier body 110, The two groups of first areas 111 are adjacent and arranged in parallel. In other words, the two groups of first areas 111 are adjacent but not close together, that is, there is a gap of a certain width between the two groups of first areas 111. The two groups of first areas 111 are respectively adsorbed and matched with the matching pieces 120. However, after the welding ribbon 400 is wound, the welding ribbon 400 between the two groups of matching pieces 120 is cut to break the welding ribbon 400 to form a group of welding ribbons 400. In this way, since the matching piece 120 is connected to the welding ribbon 400, both ends of the welding ribbon group 410 are fixed by the matching piece 120.
[0044] In other embodiments, the first carrier body 110 is a circular roller; the welding strip 400 is wound on the roller side of the first carrier 100; in other embodiments, the first carrier 100 can also be a plate-shaped carrier, or a roller with a triangular, quadrilateral, pentagon, hexagon,..., n-gonal cross-section.
[0045] The first driving component is used to drive the first carrier body 110 to rotate. The first driving component is connected to and acts on the first carrier body 110, so that the first carrier body 110 rotates clockwise or counterclockwise. In this way, when rotating clockwise, the soldering ribbon 400 can be wound in cooperation with the wiring structure; when rotating counterclockwise, the soldering ribbon 400 wound on the first carrier body 110 can be transferred to the battery cell 300. The first driving component is not shown in the figure, and the driving mode can be selected based on demand; it can be understood that counterclockwise and clockwise can be set according to actual production.
[0046] The present application also provides a processing device, such as Figure 5-11 As shown, the processing of the welding strip 400 for the battery cell 300 includes a first carrier 100 and a second carrier 200, wherein the first carrier 100 is used to lay the welding strip 400 on the battery cell 300; the second carrier 200 is used to lay the battery cell 300; wherein the first carrier 100 is the above-mentioned first carrier 100, which will not be repeated here.
[0047] The second carrier 200, such as Figure 5-7As shown, the second carrier 200 is used to arrange the battery cell 300. The second carrier 200 is arranged directly below the first carrier 100, and the first carrier 100 transfers the welding ribbon 400 downward to the second carrier 200; wherein, the second carrier 200 includes a second carrier body 210 and a second driving component, and the second carrier body 210 is used to absorb and carry the battery cell 300; the second driving component is used to drive the second carrier body 210 to move.
[0048] The second carrier body 210, such as Figure 5 As shown, the second carrier body 210 is used to absorb and carry the battery cell 300. The second carrier 200 has a third area 211 and a fourth area 212, and both the third area 211 and the fourth area 212 have an absorption function, wherein the third area 211 is used to absorb and fix the battery cell 300, and the fourth area 212 is used to absorb and fix the matching piece 120, so that one end of the welding ribbon group 410 is fixed; in one embodiment, the absorption implementation method in the third area 211 and the fourth area 212 can be the same as the absorption implementation method in the first area 111. It is worth noting that the third area 211 and the fourth area 212 can be absorbed synchronously or independently. Among them, the third area 211 is used to place the battery cell 300 and absorb and fix it, and the fourth area 212 is used to absorb the matching piece 120 on the first carrier body 110 that is pushed out by the first area 111 through inflation, so that the matching piece 120 is accurately and quickly fixed on the fourth area 212, that is, the end of the welding ribbon 400 is accurately fixed on one side of the battery cell 300 group.
[0049] In one embodiment, Figure 6 As shown, the third area 211 is set as one, the third area 211 is set at the end position of the second carrier body 210, and the fourth area 212 is set at the middle position of the second carrier body 210; in other embodiments, such as Figure 7 As shown, two third regions 211 are provided, the two third regions 211 are provided at both ends of the second carrier body 210, and the fourth region 212 is provided at the middle position of the second carrier body 210, that is, two groups of third regions 211 are provided on both sides of the fourth region 212. Figure 7 , 8 As shown, through the adsorption of the fitting 120 by the two sets of third areas 211, both ends of the welding ribbon group 410 are adsorbed and fixed, which is beneficial to the processing efficiency of the battery cell 300, and the end of the welding ribbon group 410 can be accurately and neatly transferred to one side of the battery cell 300. The adsorption structure of the third area 211 and the fourth area 212 can be the same as that of the first area 111 and the second area 112, that is, it is realized in the form of opening a through hole 113.
[0050] In one embodiment, the second carrier body 210 is in the shape of a long straight plate, and the battery cells 300 are arranged along the length direction of the second carrier body 210; in other embodiments, the second carrier body 210 may also be in other shapes, such as square, trapezoidal, circular or irregular.
[0051] The second driving component is used to drive the second carrier body 210 to move. Figure 9-11 As shown, the second driving assembly can drive the second carrier 200 in the form of a conveyor belt. Optionally, the first carrier body 110 has a degree of freedom of movement relative to the second carrier body 210 along the arrangement direction of the battery cells 300. In other words, the second carrier body 210 can be driven to move along the arrangement direction of the battery cells 300 by the first driving assembly, or by driving the first carrier 100 as a whole to move along the arrangement direction of the battery cells 300 by another driving structure. The second driving assembly is not shown in the figure, and the driving method can be selected based on demand.
[0052] The present application also provides a processing method, such as Fig.12 As shown, based on the above processing device, the battery cell 300 is processed with a welding strip 400; specifically:
[0053] S1: providing the above-mentioned processing device, so that the rotating peripheral side surface of the first carrier body 110 has the above-mentioned two groups of first areas 111 and one group of second areas 112;

[0061] S7: Connect the battery cell 300 to the welding ribbon 400 by heating and welding.
[0062] Technical effect:
[0063] 1. The first carrier body 110 provided in the present application has a first area 111 and a second area 112, and the first area 111 and the second area 112 are relatively independent. The first area 111 and the second area 112 both have adsorption functions, and the first area 111 also has an air blowing function. Since the welding strip 400 is made of metal material, that is, the welding strip 400 has a certain degree of turbulence, the welding strip 400 undergoes a certain deformation after being wound around the first carrier body 110. Through the air blowing effect on the first area 111, the end of the welding strip 400 can be flexibly and effectively transferred from the first carrier body 110 to the second carrier body 210, and the transfer efficiency of the welding strip 400 can be improved during the welding process, thereby improving the overall welding efficiency.
[0064] 2. In the present application, the matching piece 120 provided on the first carrier body 110 is adsorbed and matched with the first area 111, the welding strip 400 is wound on the first carrier body 110, and the matching piece 120 is connected to the welding strip 400. On the one hand, the matching piece 120 is used to fix the welding strip 400 to prevent the end of the welding strip 400 from being disordered after cutting; on the other hand, since the matching piece 120 has a certain area, it can be adsorbed and matched with the fourth area 212. In this way, during the transfer process of the welding strip 400, one end of the welding strip 400 is quickly and accurately fixed on the fourth area 212 through the adsorption of the matching piece 120 by the fourth area 212, that is, one end of the welding strip 400 is accurately and stably fixed to one side of the battery cell 300, without the need for other redundant clamps or presses, thereby simplifying the structure of the welding equipment.
