[0002] The segmented circular welding strip adopts the latest segmented rolling production process and is composed of circular segments + flat segments. The circular segment is welded to the front of the battery cell, and the flat segment is welded to the back of the battery cell. It can reduce the spacing between the battery cells, thereby reducing the size of the component and saving the material cost at the component end. In addition, the use of flat welding strip on the back of the battery cell can reduce the welding stress, reduce the hidden cracks at the edge of the battery cell during welding, and effectively reduce the occurrence of false welding and biased welding on the back of the battery cell.

[0003] Before performing string welding on the welding ribbon, it is necessary to cut the entire welding ribbon to obtain a length of welding ribbon suitable for welding. In the prior art, a cutter is usually used to cut multiple parallel welding ribbons as a whole. However, since the incision is under pressure during cutting, other parts of the welding ribbon will be twisted and moved, causing the welding ribbon to bend and deform, affecting the quality of the finished product after cutting.

[0004] Therefore, it is necessary to improve the prior art to overcome the above defects in the prior art. Utility Model Content

[0030] See also Figures 1 to 4 As shown, a welding strip fixing and shearing device includes a connecting seat 11 suitable for connecting to an external body, a clamping assembly 1 arranged on the connecting seat 11, positioning assemblies 2 arranged on both sides of the clamping assembly 1, and a shearing assembly 6 arranged beside the clamping assembly 1 and movable relative to the clamping assembly 1, wherein the clamping assembly 1 includes a clamping component 12 arranged on the connecting seat 11, and the welding strip to be cut is first positioned by the positioning component 2 and then clamped and fixed by the clamping component 12, and then sheared by the shearing assembly 6, thereby ensuring that the parts of the welding strip except the incision can be fixed by the clamping assembly 1 during cutting, avoiding the welding strip from twisting and deformation during the cutting process, and ensuring the quality of the finished product after cutting.

[0031] Specifically, the shearing assembly 6 includes a cutter member 61 and a first driving member 62 connected to the cutter member 61. The driving end of the first driving member 62 is extended to drive the cutter member 61 to move toward the direction close to the welding strip to cut the welding strip. In this embodiment, the first driving member 62 is a cylinder, and the cutter member 61 is a common cutter. The cutter is driven to move by the telescopic movement of the cylinder to achieve cutting and lifting.

[0032] It is worth noting that in this embodiment, two groups of clamping assemblies 1 are provided, and the cutter member 61 is provided between the two groups of clamping assemblies 1, so as to enhance the fixing effect through the clamping action of the two groups of clamping assemblies 1. In other embodiments, the number of clamping assemblies 1 provided may be selected according to actual conditions, as long as it can meet actual needs, and no specific limitation is made here.

[0033] As described above, the connecting seat 11 extends toward both sides to form an extension portion 111, and the positioning assembly 2 is installed on the extension portion 111. The positioning assembly 2 includes a positioning piece 21 connected to the extension portion 111. Each group of positioning assemblies 2 includes two parallelly arranged positioning pieces 21, thereby further enhancing the positioning and fixing effect.

[0034] In other embodiments, the number of positioning members 21 on each group of positioning components 2 may be selected according to actual conditions, such as one or more than two, etc., as long as it can meet actual needs, and no specific limitation is made here.

[0035] The positioning member 21 has a plurality of positioning grooves 211 evenly spaced apart. When positioning the solder strip, the solder strip passes through the positioning grooves 211. In the present embodiment, the corresponding positioning grooves 211 on the two groups of positioning components 2 are on the same extension line, so that one solder strip passes through the positioning grooves 211 on four positioning members 21 at the same time to ensure the positioning accuracy.

[0036] The connection seat 11 has a mounting cavity 112, and the clamping component 12 is mounted in the mounting cavity 112, and at least part of the clamping component 12 protrudes out of the mounting cavity 112 to clamp the welding strip. The clamping component 12 includes a first clamping jaw 121, a second clamping jaw 122, and an elastic member 123 arranged between the first clamping jaw 121 and the second clamping jaw 122. A shaft 113 is arranged in the mounting cavity 112, and the first clamping jaw 121 and the second clamping jaw 122 are mounted on both sides of the shaft 113. They can rotate relative to the shaft 113 under the drive of an external force, compress the elastic member 123 to store energy, thereby realizing the operation of releasing the welding strip of the clamping component 12, and then the external force disappears, and the first clamping jaw 121 and the second clamping jaw 122 rotate relative to the shaft 113 again under the elastic action of the elastic member 123, thereby realizing the operation of clamping the welding strip of the clamping component 12. In this embodiment, the elastic member 123 is a spring.

[0037] Specifically, the clamping component 12 also includes a driving plate 124 for driving the first clamping jaw member 121 and the second clamping jaw member 122 to rotate, and a driving groove 1241 is formed on the driving plate 124. The first clamping jaw member 121 and the second clamping jaw member 122 are connected to one end of the elastic member 123 and are placed in the driving groove 1241. The diameter of the driving groove 1241 gradually decreases from the opening inward. The driving plate 124 can move in the direction of approaching and moving away from the clamping component 12 under the drive of external force, thereby driving the first clamping jaw member 121 and the second clamping jaw member 122 to rotate relative to the shaft body 113, thereby driving the clamping component 12 to open or clamp the welding strip.

[0038] In order to realize the driving of the driving plate 124, the welding strip fixing and shearing device also includes a second driving component 3 disposed on the connecting seat 11, and the driving end 31 of the second driving component 3 is connected to the driving plate 124. The driving end 31 can be extended to drive the driving plate 124 to move toward or away from the clamping component 12 to realize the driving operation. In this embodiment, the second driving component 3 is a cylinder. In other embodiments, the corresponding driving member can also be selected according to the actual situation, such as an electric cylinder, an oil cylinder or a hydraulic cylinder, etc., as long as it can meet the actual needs, and no specific limitation is made here.

[0039] It is worth noting that a guide column 4 is also provided at one end of the driving plate 124 away from the clamping component 12, and a guide hole 5 is provided on the connecting seat 11. The guide column 4 cooperates with the guide hole 5 to guide so that the driving process of the driving plate 124 is more stable.

[0040] To sum up: the welding strip fixing and shearing device of the utility model is provided with a connecting seat suitable for connecting to an external body, and a clamping assembly, a positioning assembly and a shearing assembly arranged on the connecting seat, wherein the clamping assembly is suitable for clamping the welding strip to be cut, the positioning assembly is arranged on both sides of the clamping assembly, and the shearing assembly is arranged next to the clamping assembly and can be moved relative to the clamping assembly. When cutting the welding strip, the welding strip first passes through the positioning assembly for positioning and is then clamped and fixed by the clamping assembly, and then the shearing is completed by the shearing assembly, thereby ensuring that the parts of the welding strip except the incision can be fixed by the clamping assembly when cutting, avoiding the welding strip from twisting and deformation during the cutting process, and ensuring the quality of the finished product after cutting.
