[0101] The processing module 13 further comprises a punching station 133 located between the feeding station 131 and the bending station 132; the punching station 133 comprises a plurality of second bearing tables 1331 arranged along the length direction of the busbar 1 and a punching mechanism 1332, and the second bearing table 1331 and the punching mechanism 1332 are both multiple, and each punching mechanism 1332 is arranged between two adjacent second bearing tables 1331; the busbar 1 is positioned in each second bearing table 1331, and the free end to be processed (i.e. the end to be punched) extends into the punching mechanism 1332.

[0102] The punching mechanism 1332 comprises a support table 1333, a punch 1334 suspended on the support table 1333, and a punching cylinder 1335 for driving the punch 1334 to displace downward below the table surface of the support table 1333; a groove 1336 is formed below the punch 1334 on the support table 1333. The punching mechanism 1332 further comprises a sliding table 1337 for facilitating the sliding of waste in the groove 1336, which is located on the side of the support table 1333 and communicates with the groove 1336 and is arranged obliquely downward.

[0103] Each of the bearing tables comprises a limiting structure 16 for positioning the bus bar 1, the limiting structure 16 comprising a first limiting block 161 and a second limiting block 162 protruding from the bearing table, a gap for the bus bar 1 to pass through being formed between the first limiting block 161 and the second limiting block 162, the gap being consistent with the width of the bus bar 1. The first limiting block 161 and the second limiting block 162 are threadedly connected with the bearing table, so that as long as a plurality of sets of threaded holes are formed on the bearing table, the gaps between the threaded holes of each set are different, so that the size of the gap can be adjusted according to the bus bar 1 of different models, and then the limiting structure 16 can be adapted to the bus bar 1 of different models. The limiting structure 16 further comprises a first vacuum suction head 171 arranged in each bearing table and located below and opposite to the bus bar 1. The vacuum suction head is connected with a negative pressure pump air path, thereby generating a negative pressure adsorption effect. Since the vacuum suction head is prior art, no further description is given herein.

[0104] The carrying mechanism 14 is arranged above the machining module 13 and reciprocally moves between the stations to carry the bus bar 1 in the previous station to the next station. The carrying mechanism 14 comprises two sets of adsorption structures 141 for sucking the bus bar 1 in the machining module 13, and the two sets of adsorption structures 141 are respectively arranged corresponding to the adjacent two stations in the machining module 13. Each set of adsorption structures 141 comprises a plurality of second vacuum suction heads 142 arranged along the length of the bus bar 1.

[0105] The feeding device further comprises a transfer mechanism 15 for driving the machining module 13 to displace along a direction perpendicular to the conveying direction of the bus bar 1. The transfer mechanism 15 comprises a base 151, a connecting block 152 fixedly connected with the machining module 13, a driver 153 arranged on the base 151 and driving the connecting block 152 to reciprocally displace along a direction perpendicular to the conveying direction of the bus bar 1, the driver 153 being a motor or an air cylinder. The transfer mechanism 15 further comprises a sliding rail 154 arranged on the base 151, and a sliding block 155 reciprocally displacing on the sliding rail 154, the sliding rail 154 being arranged along a direction perpendicular to the conveying direction of the bus bar 1. The sliding block 155 is fixedly connected with the machining module 13, so that not only the support force of the connecting block 152 on the machining module 13 is shared, but also the movement of the machining module 13 is smoother.

[0106] According to the above structure, the specific working principle of the bus bar manufacturing process of the present application is described as follows:

[0107] When the device starts to work, the transfer mechanism 15 drives the processing module 13 to move along the direction perpendicular to the conveying direction of the busbar 1, towards the support 11, so that the feeding station 131 is located below the traction mechanism 123, facilitating the subsequent positioning of the cut busbar 1 on the third bearing table 1311 of the feeding station 131.

[0108] Firstly, the busbar 1 is conveyed from the left and right ends of the support to the corresponding cutting mechanism 122 through the feeding mechanism 121 of the two feeding modules 12, i.e. the left cutting mechanism 122 cuts the left busbar 1 into a set length, and the cut busbar 1 is pulled to the right by the left traction mechanism 123 and displaced to above the third bearing table 1311 of the feeding station 131, and is positioned on the third bearing table 1311 by the limiting structure 16 on the third bearing table 1311; at the same time, the right cutting mechanism 122 cuts the right busbar 1 into a set length, and the cut busbar 1 is pulled to the left by the right traction mechanism 123 and displaced to above the third bearing table 1311 of the feeding station 131, and is positioned on the third bearing table 1311 by the limiting structure 16 on the third bearing table 1311, so that the two feeding modules 12 simultaneously cut the busbars 1 at both ends and position them on the third bearing table 1311, and the two feeding modules do not interfere with each other, dividing the work of one feeding module 12 in the prior art into two feeding modules 12, which greatly shortens the running time of the device.

[0109] When the number of busbars 1 on the third bearing table 1311 reaches a set value, the transfer mechanism 15 drives the processing module 13 to move along the direction perpendicular to the conveying direction of the busbar 1, away from the support 11, so that the feeding station 131 is away from below the traction mechanism 123, so that the carrying mechanism 14 does not have to wait for the two traction mechanisms 123 to return to position before carrying the busbars 1 on the third bearing table 1311, realizing that the carrying operation of the carrying mechanism 14 and the returning operation of the two traction mechanisms 123 are carried out at the same time, saving the overall running time of the device and improving the running efficiency of the device.

[0110] One of the two groups of adsorption structures 141 of the conveying mechanism 14 first conveys the busbar 1 on the feeding station 131 to the punching station 133. After the punching process is completed, the two groups of adsorption structures 141 on the conveying mechanism 14 simultaneously convey the busbar 1 on the feeding station 131 and the busbar 1 on the punching station 133, respectively, place the busbar 1 on the feeding station 131 in the punching station 133, and place the busbar 1 on the punching station 133 in the bending station 132. After the punching and bending processes are completed, the two groups of adsorption structures 141 of the conveying mechanism 14 simultaneously convey the busbar 1 on the punching station 133 and the busbar 1 on the bending station 132, respectively, place the busbar 1 on the punching station 133 in the bending station 132, and place the busbar 1 on the bending station 132 in the designated finished processing area, and wait for subsequent work. The conveying mechanism 14 reciprocates between the stations according to the above working process and conveys the busbar 1 in the previous station to the next station. The conveying mechanism 14 can simultaneously convey the busbars 1 on two stations, shorten the running time of the device, and improve the feeding efficiency of the device.

[0111] As shown in Figures 9-13 The battery string position correction procedure is realized by a battery string lifting device B, which includes a correction mechanism 21 corresponding to the number of battery strings 2 to be lifted and a visual positioning mechanism (not shown in the figure) for obtaining the horizontal position of the battery strings 2 on the glass slide. Each correction mechanism 21 is arranged above the corresponding battery string 2.

[0112] Each correction mechanism 21 includes a horizontally arranged connecting rod 22, a first adsorption structure 23 for horizontally positioning the battery string 2 below the connecting rod 22, and a driving unit 24 for driving the connecting rod 22 to change position in the horizontal direction. Here, the horizontal direction refers to movement along the X-axis or the Y-axis, or rotation in the horizontal direction. The length direction of the battery string 2 corresponds to the Y-axis direction, and the width direction of the battery string 2 corresponds to the X-axis direction.

[0113] The connecting rod 22 is a telescopic structure, which can adapt to the lifting needs of battery strings 2 of different length specifications.

[0114] The driving unit 24 comprises a first connecting block 241 fixed above the connecting rod 22, a first driver 242 driving the first connecting block 241 to displace along the Y axis; wherein the first connecting block 241 is located at the middle part of the connecting rod 22; further comprises a second connecting block 243 fixed above the connecting rod 22, a second driver 244 driving the second connecting block 243 to displace along the X axis; wherein the second connecting block 243 is arranged in a spaced manner with the first connecting block 241. In this way, when a certain battery string 2 needs to be corrected in the Y axis position, only the first connecting block 241 is driven to displace in the Y axis by the first driver 242 of the corresponding correction mechanism 21, so that the corresponding connecting rod 22 and the battery string 2 positioned below the connecting rod 22 can be driven to displace in the Y axis; when a certain battery string 2 needs to be corrected in the X axis position, only the second connecting block 243 is driven to displace in the X axis by the second driver 244 of the corresponding correction mechanism 21, so that the corresponding connecting rod 22 and the battery string 2 positioned below the connecting rod 22 can be driven to displace in the X axis. The first driver 242 and the second driver 244 both comprise a stationary part a and a moving part b, one of the two parts is provided with an inductor d, and the other is provided with an inductor c, so that when the moving part b is displaced to adhere to the stationary part a, the moving part b stops displacement.

[0115] The second connecting block 243 is provided with two, and the second driver 244 is provided with two, two second drivers 244 respectively driving two second connecting blocks 243 to displace along the X axis; two second connecting blocks 243 are arranged on both sides of the first connecting block 241, so as to realize the rotation or displacement along the X axis of the connecting rod 22 by driving two second drivers 244. When a certain battery string 2 needs to be rotated in the horizontal direction to correct the position, only two second connecting blocks 243 are driven to displace in opposite directions by two second drivers 244 of the corresponding correction mechanism 21, so that the corresponding connecting rod 22 and the battery string 2 positioned below the connecting rod 22 can be rotated.

[0116] The driving unit 24 further comprises two third connecting blocks 28 connected below the connecting plate 26 to assist the rotation of the connecting rod 22, and two third connecting blocks 28 are arranged on both sides of the first connecting block 241 and fixedly connected with the connecting rod 22.

[0117] The battery string lifting device B further comprises a vertically arranged fixing support 25, and a third driver 29 is fixedly connected to the upper portion of the fixing support 25 and used for driving the fixing support 25 to move in the Z-axis direction. A connecting plate 26 is horizontally fixed to the lower portion of the fixing support 25, and each driver is fixedly connected to the connecting plate 26. The connecting rod 22 is connected to the lower portion of the connecting plate 26. A strip-shaped hole 261 corresponding to the displacement stroke of each connecting block is formed in the upper portion of the connecting plate 26 corresponding to each connecting block. Each driver drives each connecting block to displace through a guide rod 27. Each guide rod 27 penetrates through each strip-shaped hole 261, and the upper end of the guide rod 27 is assembled and connected to each driver, and the lower end is fixedly connected to each connecting block.

[0118] The first driver 242, the second driver 244 and the third driver 29 can be one of a motor and a pneumatic cylinder.

[0119] The first adsorption structure 23 is fixedly connected to the connecting rod 22, and the first adsorption structure 23 comprises a suction cup 231 and a vacuum negative pressure gauge 232 used for detecting the vacuum degree in the suction cup 231. The suction cup 231 is fixedly arranged at the lower portion of the connecting rod 22.

[0120] According to the above structure, the specific working principle of the battery string position deviation correction process of the application is described as follows:

[0121] Firstly, the battery string lifting device B is driven by the third driver 29 to move to the upper portion of the battery string 2 to be lifted, and then the battery string lifting device B moves downward along the Z-axis. In the process of moving, the visual positioning mechanism obtains the horizontal positions of the battery strings 2 on the glass slide, and then the first adsorption structure 23 positions each battery string 2 on the glass slide below the connecting rod 22 of each correction mechanism 21, and corrects the horizontal position through the position information of each battery string 2 obtained by the visual positioning mechanism.

[0122] When a certain battery string 2 needs to be corrected in the Y-axis position, the first connecting block 241 is driven to move in the Y-axis direction by the first driver 242 of the corresponding correction mechanism 21, so as to drive the corresponding connecting rod 22 and the battery string 2 positioned below the connecting rod 22 to move in the Y-axis direction.

[0123] When a certain battery string 2 needs to be corrected in the X-axis position, the second connecting block 243 is driven to move in the X-axis direction by the second driver 244 of the corresponding correction mechanism 21, so as to drive the corresponding connecting rod 22 and the battery string 2 positioned below the connecting rod 22 to move in the X-axis direction.

[0124] When a certain battery string 2 needs to be rotated horizontally to correct the position, as long as the two second drivers 244 of the corresponding correction mechanism 21 are driven to displace the two second connecting blocks 243 in opposite directions, the corresponding connecting rod 22 and the battery string 2 positioned below the connecting rod 22 can be rotated.

[0125] After the correction is completed, the battery string 2 can be moved to the welding station by the battery string lifting device B, waiting for alignment and assembly with the bus bar 1, and realizing the final welding process. Through the position correction of the battery string 2, the welding precision and yield of the product can be greatly improved.

[0126] As shown in Figures 14-17 , it also includes a pad mechanism for welding the bus bar 1, which includes a pad structure 31 arranged along the length direction of the bus bar 1. The pad structure 31 is provided with at least one group. When the pad structure 31 is provided with two or more groups, each group of pad structures 31 is arranged in a long strip shape along the length direction of the bus bar 1, which can adapt to the positioning needs of bus bars 1 of different lengths.

[0127] The pad structure 31 includes at least one positioning block 311 for bearing and supporting the bus bar 1, and an elastic support block 312 arranged below the positioning block 311 and corresponding to the positioning block 311. When the positioning block 311 is one, the length of the positioning block 311 corresponds to the length of the bus bar 1. When the positioning block 311 is multiple, each positioning block 311 is arranged in a long strip shape along the length direction of the bus bar 1 to adapt to bus bars 1 of different lengths.

[0128] The pad structure 31 also includes a support plate 314 arranged along the length direction of the bus bar 1, and a U-shaped support frame 313 arranged below the support plate 314. The support plate 314 is arranged above the support frame 313. The lower surface of the support plate 314 is fixedly connected with a rib plate 315 for improving the strength of the lower surface. The support plate 314 is provided with a groove 317 corresponding to each elastic support block 312. Each elastic support block 312 is positioned in each groove 317. Each positioning block 311 is arranged corresponding to each groove 317 and protrudes upward from the groove 317, for bearing and supporting the bus bar 1.

[0129] The base plate mechanism further comprises a second adsorption structure 32 for positioning the bus bar 1 on the upper surface of the positioning block 311, the second adsorption structure 32 comprises a second suction head 321 for adsorbing the bus bar, a guide block 326 sleeved on the outer periphery of the second suction head 321, a connecting block 322 arranged below the supporting plate 314 for supporting the supporting plate 314; the guide block 326 is positioned below the supporting plate 314. The second suction head 321 is connected to the connecting block 322, and the air inlet of the second suction head 321 corresponds to the upper surface of the supporting plate 314. During adsorption, the air inlet of the second suction head 321 is attached to the bottom of the bus bar positioned on the positioning block 311; the connecting block 322 is provided with an air path hole 323, which is in air communication with the air path of the second suction head 321. The second adsorption structure 32 can make the bus bar 1 more accurately positioned on the positioning block 311, and the position will not change during welding to ensure the welding quality.

[0130] The second adsorption structure 32 is provided with at least one group; when the second adsorption structure 32 is provided with two or more groups, the air path holes 323 on the connecting blocks 322 are in air communication through air pipes 324.

[0131] The second adsorption structure 32 further comprises a one-way air cylinder 325 for driving the second suction head 321 to move up and down. When the bus bar 1 to be positioned is displaced downward to the positioning block 311, the one-way air cylinder 325 drives the second suction head 321 to displace upward and higher than the upper surface of the positioning block 311 to accommodate the bus bar 1 to be positioned. When the air inlet of the second suction head 321 is attached to the bus bar 1, the one-way air cylinder 325 drives the second suction head 321 to displace downward, so that the bus bar 1 is finally positioned on the upper surface of the positioning block 311. At this time, the second suction head 321 is still in the adsorption state and remains until the end of the welding process. In this way, the bus bar 1 can be more accurately positioned on the positioning block 311, and the position will not change during welding to ensure the welding quality. The upper end of the one-way air cylinder 325 is connected with the second suction head 321, and the lower end is fixedly connected with the supporting block 322.

[0132] The working principle of the base plate mechanism is as follows: when the bus bar 1 to be positioned is displaced downward to the positioning block 311, the one-way air cylinder 325 drives the second suction head 321 to displace upward and accommodate the bus bar 1. When the air inlet of the second suction head 321 is attached to the bus bar 1, the second suction head 321 displaces downward with the bus bar 1, so that the bus bar 1 is finally positioned on the upper surface of the positioning block 311 and continuously adsorbed until the end of the welding process.

[0133] In the welding process, the welding head can exert a pressure on the busbar 1 to ensure the welding effect. Since the elastic supporting block 312 is arranged below the positioning block 311, the pressure exerted on the busbar 1 can be relieved, so that the busbar 1 is not damaged and the effective welding operation is not affected, and the welding quality of the busbar is improved.

[0134] The workflow of the present application is summarized as follows:

[0135] The left and right busbars 1 need only to be cut into a set length, without punching and bending processing. The middle busbar 2 needs to be cut, punched and bent. The left and right busbars 1 are first cut into a set length by the feeding module 12, and then conveyed to a set position to wait for the middle busbar 1. After being cut by the feeding module 12 and being bent (and punched) by the processing module 13, the middle busbar 1 is conveyed to be combined with the left and right busbars 1. Then the three busbars 1 are all carried to the pad mechanism and positioned according to the specified arrangement, and after positioning, they are conveyed to a welding station to wait for welding.

[0136] The two groups of battery strings 2 to be welded are first arrayed on a glass slide, and are conveyed to be directly below the welding station together with the glass slide. Then the battery string lifting device B vertically lifts the battery strings 2 on the glass slide. During or after lifting, the visual positioning mechanism obtains the position and posture of each battery string 2, and corrects the position deviation of the battery string 2. After correction, the battery string 2 is displaced by the battery string lifting device B to the welding station to wait for alignment and welding assembly with the busbar 1.

[0137] When each busbar 1 and each battery string 2 are prepared, the busbar 1 is located directly below the welding strip of the two groups of battery strings 2. Then the busbar 1 is close to and contacts the welding strip on the side of the battery string 2, and then the welding device C can press down the welding strip of the battery string 2 by battery welding, so that the welding strip of the battery string 2 is welded and combined with the busbar 1 (see Figure 18 ).

[0138] The welding device C is a prior art, so it is not described here.

[0139] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application should be covered within the protection scope of the present application.
