Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] like Figure 2 As shown, this application preferentially proposes a tape fixing assembly 3, which includes a tape pressing member 31 and a second driving member 32 for driving the tape pressing member 31 to fix the welding strip. The second driving member 32 can drive the tape pressing member 31 to press the flat welding strip or release the flat welding strip.

[0026] Specifically, the number of pressing members 31 matches the number of welding strips, and each pressing member 31 has a groove at its top end. Each groove has an opening on the same side, so that the second driving member 32 drives the pressing member 31 to place the welding strip in the groove of the pressing member 31, that is, the strip placement position of the fixing assembly 3. The groove on the fixing member 31 fixes the position of the flat welding strip, so that the position of the welding strip does not move.

[0027] The tape fixing assembly 3 in this application also includes a mounting base 1 and a support 34. The second drive component 32 is connected to the mounting base 1. The top of the support 34 is provided with a tape placement position for holding the flat welding tape. The flat welding tape needs to be placed on the tape placement position of the tape fixing assembly 3 by an external mechanism. The second drive component 32 drives the groove of the pressing component 31 to press the flat welding tape onto the tape placement position on the top of the support 34, thereby pressing and fixing the flat welding tape.

[0028] like Figure 3 , Figure 5 As shown, the belt assembly 3 also includes a drive plate 33 that is limitedly connected to the bottom of the pressing member 31. The pressing member 31 is rotatably connected to the support 34 via a rotating shaft 35. A spring 36 is also provided on one side of the pressing member 31, abutting against the pressing member 31 and the support 34. The driving end of the second driving component 32 is connected to the drive plate 33, and is used to drive the drive plate 33 to move horizontally while driving the bottom of the pressing member 31 to rotate around the rotating shaft 35, so as to drive the top of the pressing member 31 to rotate open or close. The second driving component 32 drives the drive plate 33 and the bottom of the pressing member 31 connected to it to rotate around the rotating shaft 35. During rotation, the spring 36 is compressed, and the top of the pressure strip 31 is opened, allowing the welding strip to be placed into or removed from the feeding position of the fixing assembly 3. When the second drive component 32 returns to its original position, the spring 36 returns to its initial state, and the lower end of the pressure strip 31 rotates around the rotating shaft 35 under the action of the spring 36, causing the top of the pressure strip 31 to close, pressing the welding strip on the feeding position of the fixing assembly 3 onto the top of the support 34, thereby pressing and fixing the welding strip evenly, so that the position of the welding strip does not move when the cutter assembly 2 cuts the welding strip, making the cutting more stable and further ensuring the accuracy and flatness of the cut end of the welding strip.

[0029] In some embodiments, refer to Figure 5 As shown, the drive plate 33 is provided with several U-shaped grooves, and the bottoms of several pressing members 31 are placed in the U-shaped grooves and in contact with the side walls of the U-shaped grooves. Each pressing member 31 is provided with a corresponding U-shaped groove. The bottom end of the pressing member 31 is elastically abutted against the U-shaped groove under the elastic force of the spring 36. While the second drive component 32 drives the drive plate 33 to translate, it also drives the bottom end of the pressing member 31 placed in the U-shaped groove to rotate around the rotating shaft 35, opening the top of the pressing member 31. After the welding strip is placed in the strip placement position of the fixed strip assembly 3, the second drive component... 32 drives the drive plate 33 to move in the opposite direction. The bottom of the pressing piece 31 is about to separate from the side wall of the U-shaped groove, but under the elastic force of the spring 36, the pressing piece 31 returns to its original position, so that the welding strip enters the groove from one side of the groove opening of the pressing piece 31. The bottom surface of the welding strip is placed on the top of the support 34, and at the same time, the welding strip placed in the feeding position of the fixed strip assembly 3 is pressed tightly. The bottom end of the pressing piece 31 always elastically abuts against the side wall of the U-shaped groove. The welding strip is placed in the feeding position of the fixed strip assembly 3 without any positional change, ensuring the cutting accuracy of the welding strip.

[0030] In some embodiments, such as Figure 5 As shown, the support 34 is provided with a limiting groove 37 that matches the number of welding strips to be cut. The limiting groove 37 is located on one side of the pressing member 31 extending along the length of the welding strip and on the other side of the cutting assembly 2 that works together with the pressing member 31. Before the pressing member 31 presses the welding strip, the welding strip is placed in the limiting groove 37 to position both sides of the welding strip so that the welding strip does not shift when the pressing member 31 presses the welding strip. In addition, it is convenient for the welding strip to be placed into the limiting groove 37. The top of the limiting groove 37 is provided with an opening, and the opening is V-shaped.

[0031] Specifically, in another embodiment, such as Figure 6 As shown, the tape fixing assembly 3 includes a connecting plate 38 fixedly connected to the pressing member 31. The second driving component 32 includes a lifting mechanism 321, a lifting seat 323, and a second translation drive 322. The connecting plate 38 is vertically connected to the lifting seat 323 via the lifting mechanism 321. The lifting mechanism 321 is horizontally slidably connected to the mounting base 1 via the lifting seat 323. The driving end of the second translation drive 322 is connected to one end of the lifting seat 323. The lifting mechanism 321 and the second translation drive 322 jointly drive the pressing member 31 connected to the connecting plate 38, causing the pressing member 31 to rise, fall, and translate, thus avoiding the tape placement position of the tape fixing assembly 3. This allows the welding strip to be placed in the groove of the pressing member 31 from the opening side of the groove. The bottom surface of the welding strip is placed on the top of the support 34. The lifting mechanism 321 and the second translation drive 322 are driven again to press and fix the flat surface of the welding strip between the support 34 and the pressing member 31.

[0032] In some embodiments, an air passage is provided inside the mounting base 1. The air passage is connected to at least the second driving component 32. The second driving component 32 is configured as a cylinder. The cylinder body is directly connected to the mounting base 1. The air passage on the mounting base 1 communicates with the inside of the cylinder body and is connected to the external air through the air passage. The air passage is located inside the mounting base 1, which simplifies the air path arrangement on the tape cutting assembly 100, reduces the number of exposed air pipes, and makes the structure of the tape cutting assembly 100 simpler.

[0033] It should be noted that the air passage can be set to two or more sets, and the air passage can also be individually connected to other pneumatic components on the cutting assembly 100, connecting different pneumatic components and external air sources through different air passages.

[0034] On the other hand, this application also proposes a belt-making mechanism, such as Figure 7As shown, the tape-making mechanism includes multiple tape-cutting assemblies 100 arranged side by side, and a spacing mechanism 200 drivenly connected to the multiple tape-cutting assemblies 100. The spacing mechanism 200 is used to drive the multiple tape-cutting assemblies 100 to move closer or further away from each other. Here, the spacing mechanism 200 is preferably driven by a motor synchronous belt. One tape-cutting assembly 100 is installed on each of the two opposite strips of the same synchronous belt. When the motor drives the synchronous belt, the tape-cutting assemblies 100 connected to the opposite strips of the synchronous belt move in the opposite direction, moving closer or further away in the opposite direction. Similarly, multiple motor synchronous belt mechanisms are connected to a multiple number of tape-cutting assemblies 100 to drive all tape-cutting assemblies 100 to move closer or further away from each other at the same time, so as to arbitrarily adjust the distance between each tape-cutting assembly 100, adjust the cutting length of each cut welding strip, or adjust the spacing of each welded strip after cutting, so that the cut ends of each welded strip are far apart from each other, do not collide, and do not affect the straightness of the cut ends of the welded strip.

[0035] like Figure 1 , Figure 2 As shown, the present application proposes a strip cutting assembly 100 including: a mounting base 1, and a strip fixing assembly 3 connected to the mounting base 1. The strip fixing assembly 3 is disposed on both sides of the cutting assembly 2 in the extension direction of the welding strip. The cutting assembly 2 includes a cutting base 27 and an upper cutting blade 21 and a lower cutting blade 22 movably connected to the cutting base 27 and arranged vertically opposite each other, and a first driving component 23 for driving the upper cutting blade 21 and the lower cutting blade 22 to move in opposite directions. The blade of the upper cutting blade 21 and the blade of the lower cutting blade 22 are arranged vertically opposite each other, and at least one side of the blade of the upper cutting blade 21 is provided with a clearance for the welding strip to enter between the upper cutting blade 21 and the lower cutting blade 22. The strip fixing assembly 3 includes a pressing component 31 and a second driving component 32 for driving the pressing component 31 to fix the welding strip. The second driving component 32 can drive the pressing component 31 to press down the flat welding strip or release the flat welding strip.

[0036] In some embodiments, both sides of the upper cutter 21 and the lower cutter 22 are provided with clearance openings, allowing the welding strip to enter between the upper cutter 21 and the lower cutter 22 from either side.

[0037] When cutting the flat welding strip, the first driving component 23 drives the upper cutter 21 and the lower cutter 22 to move out of the strip placement position on the cutter assembly 2, and the second driving component 32 drives the pressing component 31 to move out of the strip placement position on the fixed component 3. The flat welding strip needs to be placed on the strip placement position of the cutter assembly 2 and the fixed component 3 by an external mechanism. The flat welding strip is put between the upper cutter 21 and the lower cutter 22 through the clearance opening. The second driving component 32 drives the pressing component 31 to press the flat welding strip placed on the strip placement position of the fixed component 3. Then, the first driving component 23 drives the upper cutter 21 and the lower cutter 22 to move in opposite directions at the same time to cut the welding strip located on the strip placement position on the cutter assembly 2. The position of the cut welding strip does not change before and after the cut, ensuring that the welding strip is cut at the placement position in one go. The cut end of the welding strip will not bend or deform, and the welding strip will not stand on its side. This makes the cut end of the welding strip flat and beautiful, and does not affect the quality of welding the welding strip to the battery cell into a battery string.

[0038] In some embodiments, such as Figure 3 , Figure 4 As shown, the cutter assembly 2 includes a limiting seat 24 connected to the driving end of the first driving component 23. The limiting seat 24 is movably connected to the cutter seat 27 via a pin 25. The limiting seat 24 is connected to the upper cutter 21 and the lower cutter 22 via a camshaft 26. The upper cutter 21 and the lower cutter 22 are movably fitted onto the cutter seat 27. While the first driving component 23 drives the limiting seat 24 to move horizontally along the direction perpendicular to the length of the welding strip, it also drives one end of the camshaft 26 to swing, thereby driving the upper cutter 21 and the lower cutter 22 connected to the other end of the camshaft 26 to move in opposite directions. This causes the upper cutter 21 and the lower cutter 22 to move in opposite directions and simultaneously contact the two flat surfaces of the flat welding strip to cut the flat welding strip. The height of the cut welding strip end does not change, thus avoiding bending and deformation of the cut welding strip end.

[0039] Specifically, refer to Figure 4 As shown, both the upper cutter 21 and the lower cutter 22 are provided with through holes that are tangential to the cam surface of the first end of the camshaft 26. The two through holes correspond to the two protrusions on the camshaft 26. The second end of the camshaft 26 is provided with a crank that extends to tangentially engage with the inner wall of the slot on the limit seat 24. When the first drive component 23 drives the limit seat 24 to move horizontally, it causes the second end of the crank to swing, while the upper cutter 21 and the lower cutter connected to the protrusion at the first end of the camshaft 26 move up and down in opposite directions.

[0040] In other embodiments, the movable connection between the upper cutter 21 and the lower cutter 22 and the cutter holder 27 further includes the upper cutter 21 and the lower cutter 22 being slidably connected to the cutter holder 27. The first driving component 23 simultaneously drives the upper cutter 21 and the lower cutter 22 to move closer or further apart from each other. The first driving component 23 can be a motor synchronous belt structure, with the upper cutter 21 and the lower cutter 22 respectively connected to the two opposite sides of the same synchronous belt. The motor simultaneously drives the upper cutter 21 and the lower cutter 22 to move in opposite directions. Alternatively, the first driving component 23 can be a gear and rack structure, with the upper cutter 21 and the lower cutter 22 respectively meshed with the rack on both sides of the shaft of the same gear. While driving the gear to rotate, the upper cutter 21 and the lower cutter 22 are driven to move in opposite directions.

[0041] In some embodiments, refer to Figure 3 As shown, the cutter assembly 2 also includes a first translation drive 28 fixedly connected to the mounting base 1, and a connecting rod 29 connected to one end of the first translation drive 28. The cutter seat 27 is slidably connected to the mounting base 1, and the other end of the connecting rod 29 is fixedly connected to the cutter seat 27. The upper cutter 21 and the lower cutter 22 are movably attached to the cutter seat 27 through a connector. The first translation drive 28 is used to drive one end of the connecting rod 29, so that the cutter seat 27 connected to the other end of the connecting rod 29 and the upper cutter 21 and the lower cutter 22 connected to the cutter seat 27 are translated as a whole, thereby moving the upper cutter... The upper cutter 21 and the lower cutter 22 move along the side of the clearance opening to expose the strip placement position of the welding strip at the cutter assembly 2. After the welding strip is placed at the strip placement position of the cutter assembly 2, the first translation drive 28 drives the upper cutter 21 and the lower cutter 22 to translate together towards the clearance opening. The welding strip located at the strip placement position on the cutter assembly 2 is entered from the clearance opening between the upper cutter 21 and the lower cutter 22. The welding strip is placed in the strip placement position of the cutter assembly 2 (i.e., between the upper cutter 21 and the lower cutter 22) without any positional change. The upper cutter 21 and the lower cutter 22 directly take the welding strip.
