[0027] As Figures 1 to 5 shown, the present application discloses a battery string end welding strip flattening device, the disclosed battery string end welding strip flattening device comprises a string loading table 100, a string moving hand 200 and a pressing assembly 300.

[0028] Specifically, the string carrying hand 200 and the string carrying table 100 are arranged in sequence along the direction of gravity, the string carrying hand 200 can be lifted and moved relative to the string carrying table 100, the pressing assembly 300 is arranged on one end of the string carrying hand 200, and the string carrying hand 200 is provided with a plurality of suction cups arranged along the length of the battery string, and the pressing surface of the pressing assembly 300 faces the same direction as the suction cup surface of the plurality of suction cups.

[0029] In the use process of the battery end welding strip flattening device, since the battery string is precisely cut according to the preset string length, the bent welding strip is always located on one side of the battery string, and the bent welding strip does not exist on both ends of the battery string. When the string carrying hand 200 carries the cut battery string from the string carrying table 100, the plurality of suction cups arranged on the string carrying hand 200 adsorb a plurality of battery pieces in the battery string, and at the same time, the pressing surface of the pressing assembly 300 can press one end of the battery string with the exposed bent welding strip on the string carrying table 100, so that the exposed welding strip is straightened.

[0030] The above structure arranges the pressing assembly 300 on one side of the string carrying hand 200, and presses and corrects one end of the battery string with the exposed bent welding strip on both ends of the battery string when the string carrying hand 200 carries the battery string, thereby avoiding that the edge of the battery piece at the end of the battery string is cracked due to the stress of the bent welding strip when the welding bus bar is welded.

[0031] In an alternative, the pressing assembly 300 can include a deformation connector and a pressing plate 330. Specifically, one end of the deformation connector is connected to the base 340, and the other end of the deformation connector is connected to the pressing plate 330. The deformation connector can be a rubber connector, a sponge connector, a spring, etc., and the application does not make any limitation thereon. The deformation connector achieves flexible pressing of the pressing plate 330 by itself.

[0032] In another alternative, the pressing assembly 300 can include a guide rod 310, a spring 320, a pressing plate 330, and a base 340. Specifically, the base 340 is arranged on one end of the string carrying hand 200, the guide rod 310 is in sliding fit with the through hole of the base 340, one end of the guide rod 310 passes through the through hole and is connected to a limiting block, the limiting block is in limiting fit with the base 340, the other end of the guide rod 310 is connected to the pressing plate 330, and the spring 320 is sleeved on the guide rod 310 and elastically contacts the pressing plate 330 and the base 340 at both ends.

[0033] In the above structure, the sliding fit of the guide rod 310 with the through hole can ensure the pressing accuracy of the pressing plate 330, and avoid the deflection of the pressing plate 330 when moving, and the spring 320 can buffer the pressing force of the pressing plate 330, thereby avoiding the welding strip being pressed and injured.

[0034] In addition, the pressing assembly 300 can include a telescopic driving member and a pressing plate. Specifically, the base 340 is arranged at one end of the string carrying hand 200, the telescopic driving member is arranged on the base 340, and the pressing plate is arranged on the driving end of the telescopic driving member. When the string carrying hand 200 carries the cut battery string from the string loading table 100, the plurality of suction cups arranged on the string carrying hand 200 suck a plurality of battery pieces in the battery string, and at the same time, the telescopic driving member drives the pressing plate to press one end of the exposed bending welding belt in the two ends of the battery string on the string loading table 100, so that the exposed welding belt is pressed straight. Of course, the telescopic driving member can be a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, etc., and the present application does not make any limitation thereto.

[0035] In the embodiment of the present application, the distance between the suction cup surface and the pressing surface in the direction of gravity can be equal to the retraction distance of the suction cup. When the suction cup is in contact with the plurality of battery pieces in the battery string, the suction cup will be compressed and deformed. In the retraction process, the pressing surface of the pressing assembly 300 gradually approaches one end of the exposed bending welding belt in the two ends of the battery string. After complete retraction, the pressing assembly 300 presses the bending welding belt to straighten it.

[0036] In the embodiment of the present application, the string loading table 100 can include a conveying belt channel 110 and a support 120. Specifically, the support 120 is arranged at one end of the conveying belt channel 110, and the support 120 is arranged opposite to the pressing assembly 300 in the direction of gravity. Since the conveying belt of the conveying belt channel 110 is insufficient in rigidity, the support 120 can support one end of the exposed bending welding belt in the two ends of the battery string, thereby ensuring the pressing effect of the pressing assembly 300 on the bending welding belt.

[0037] In a further technical solution, the support surface of the support 120 can be coplanar with the bearing surface of the conveying belt channel 110, thereby avoiding the bending welding belt being pressed and bent again by the pressing assembly 300.

[0038] In an alternative solution, the support 120 can include a first support sub-member 121, a second support sub-member 122 and a third support sub-member 123. Specifically, the first support sub-member 121 and the second support sub-member 122 are arranged on the two sides of the conveying belt channel 110, respectively, and the third support sub-member 123 is arranged on the conveying belt channel 110 and located between the first support sub-member 121 and the second support sub-member 122.

[0039] Since the conveying belt in the conveying belt channel 110 is insufficient in rigidity, and the contact area between the conveying belt and the battery string is small, which avoids scratching the surface of the battery string, the conveying belt channel 110 will be provided with a support plate to support the conveying belt. The first support sub-member 121, the second support sub-member 122 and the third support sub-member 123 and the conveying belt can form a support platform, thereby ensuring that the end of the battery string with the bending welding belt can be completely supported by the support platform, and thereby facilitating the overall pressing of the plurality of bending welding belts by the pressing assembly 300.

[0040] In still another step of the technical solution, the battery string loading table 100 can further include a driving member 410 and a normalizing member 420, specifically, the driving member 410 is arranged on the conveying belt channel 110, and the normalizing member 420 is arranged on the driving end of the driving member 410. Before the battery string is carried by the battery string carrying hand 200, the driving member 410 can drive the normalizing member 420 to move and contact the battery string, and the normalizing member 420 is matched. Of course, the driving member 410 can be a pneumatic cylinder, an electric cylinder, etc., and the present application does not make any limitation on this.

[0041] In addition, the driving member 410 can be a bidirectional pneumatic cylinder, and the normalizing member 420 can be two, and arranged on the two driving ends of the bidirectional pneumatic cylinder respectively, and the two normalizing members 420 can be close to or away from each other, and before the battery string is carried by the battery string carrying hand 200, the bidirectional pneumatic cylinder can drive the two normalizing members 420 to move and contact the battery string, and the normalizing member 420 is matched.

[0042] In the embodiment of the present application, the base 340 can include a base plate and a mounting member, specifically, the base plate is arranged on one end of the battery string carrying hand 200, and the mounting member is connected with the base plate through fasteners (for example, screw thread connection), and the mounting member is further threadedly connected with a set screw, one end of the set screw is in contact with the base plate, and the pressing assembly 300 is connected with the mounting member.

[0043] In the above structure, the set screw can adjust the distance between the mounting member and the base plate, thereby indirectly adjusting the distance between the pressing assembly 300 and the battery string carrying hand 200, and further facilitating the control of the distance between the pressing surface and the suction cup surface.

[0044] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
