[0052] Each of the mobile modules 3 includes a mounting frame 31 and a tool picking mechanism 35 for picking up a pressing tool, and at least some of the mobile modules 3 also include a solder strip cutting mechanism 36 for cutting a solder strip, and the solder strip cutting mechanism 36 is arranged on one side of the tool picking mechanism 35 on the same mounting frame 31.

[0053] After the welding strip cutting mechanism 36 has finished cutting the welding strip, each of the tool picking mechanisms 35 places the picked-up pressing tool on a corresponding group of welding strip segments.

[0054] The welding strip cutting and positioning device provided by the present invention can cut the welding strip when producing a battery string, and place a clamping tool on each group of cut welding strip segments to position the welding strip, which can effectively improve the production efficiency of the battery string.

[0055] The welding ribbon cutting and positioning device provided by the present invention is described in detail below according to a specific implementation manner.

[0056] In a specific embodiment, Figure 1 and Figure 2 As shown, the first to nth mobile modules 3 are arranged in sequence along the direction from the first end to the second end of the rack 1 ( Figure 1 and Figure 2 The right end is the first end, and the left end is the second end);

[0057] A soldering ribbon cutting mechanism 36 is respectively disposed on the second to nth mobile modules 3 , and the soldering ribbon cutting mechanism 36 is disposed on a side of the tooling picking mechanism 35 on the same mounting frame 31 close to the first end.

[0058] Thus, when the solder strip cutting and positioning device is used to process the solder strip, Figure 8 As shown, n carrying components 200 are arranged along a straight line at intervals, wherein each carrying component 200 includes a battery cell carrying portion and a solder strip carrying portion, the battery cell carrying portion 200 includes at least two first supporting portions for carrying battery cells, and the solder strip carrying portion includes at least one second supporting portion for carrying the solder strip; a battery cell is placed on the battery cell carrying portion of each carrying component 200;

[0059] The welding tape traction device 300 tractions the welding tape 100 to extend above a plurality of spaced-apart carrying components 200, and places the welding tape cutting and positioning device above the pulled welding tape 100, wherein the first moving module at the first end of the welding tape cutting and positioning device is close to the end position of the welding tape, the welding tape cutting mechanism 36 on the second moving module cuts at A to obtain the first group of welding tape segments, the welding tape cutting mechanism 36 on the third moving module cuts at B to obtain the second group of welding tape segments, and so on, cutting the welding tape at C, D, and E respectively, the welding tape cutting mechanism 36 on the nth moving module cuts to obtain the n-1th group of welding tape segments, and the last group of welding tape segments (i.e., the nth group of welding tape segments) can be cut by other cutting mechanisms located between the film tape providing device and the welding tape cutting and positioning device, such as Figure 8 The last group of welding strip segments in the process is cut at F by other cutting devices.

[0060] Then, the tool picking mechanism 35 on each mobile module 3 places the picked up pressing tool on each corresponding group of welding tape segments. Specifically, the tool picked up by the tool picking mechanism 35 on the first mobile module is placed on the front section of the first group of welding tape segments (the front section of each group of welding tape segments is stacked on the battery cell); the tool picked up by the tool picking mechanism 35 on the second mobile module is placed on the front section of the second group of welding tape segments... The tool picked up by the tool picking mechanism 35 on the nth mobile module is pressed on the front section of the nth group of welding tape segments. Among them, when the rear half of each group of welding tape segments is located on the second support portion of the bearing component 200, the front half is stacked on the battery cell of the first support portion of the same bearing component 200.

[0061] Then, n supporting components 200 are plugged together. When two adjacent supporting components 200 are arranged such that the first supporting portion of the latter supporting component and the second supporting portion of the former supporting component are staggered and plugged together, the welding strip on the second supporting portion of the former supporting component is stacked below the battery cell on the latter supporting component.

[0062] It can be understood that the configuration is not limited to the above-described configuration of the solder tape cutting mechanism 36 on the nth mobile module to cut the n-1th group of solder tape segments. In the case of adaptive modifications to the installation of the solder tape cutting mechanism, the solder tape cutting mechanism on the nth mobile module can also be used to cut the nth group of solder tape segments, and the clamping tool picked up by each tool picking mechanism is released on the solder tape segment cut by the solder tape cutting mechanism of the same mobile module.

[0063] In this embodiment, each of the mobile modules 3 further includes a solder strip positioning component mounted on the mounting frame 31 for positioning the solder strip. Before the solder strip cutting mechanism 36 cuts the solder strip, the solder strip positioning component positions the solder strip.

[0064] Specifically, Figure 3 and Figure 4 As shown, the welding strip positioning component includes a first welding strip positioning component 37 disposed on a first side of the tool picking mechanism 35 on the same mounting frame 31 and a second welding strip positioning component 38 disposed on a second side of the tool picking mechanism 35 on the same mounting frame 31;

[0065] The first solder strip positioning component 37 can be a solder strip positioning plate with a plurality of side-by-side limiting grooves at the lower end, and the second solder strip positioning component 38 can be a solder strip positioning plate with a plurality of side-by-side limiting grooves at the lower end. When each of the moving modules 3 moves downward to a preset position, the plurality of parallel solder strips located below enter the limiting grooves of the first solder strip positioning component 37 and the second solder strip positioning component 38 respectively. Specifically, the first solder strip positioning component 37 limits the rear section of the corresponding group of solder strip segments, and the second solder strip positioning component 38 limits the front section of the corresponding group of solder strip segments. Reference Figure 8 The portion of each group of welding strip segments carried by each carrying component 200 close to the right end is the front portion, and the portion close to the left end is the rear portion.

[0066] It can be understood that the first welding strip positioning component 37 can also be a welding strip clamping mechanism including a plurality of side-by-side clamping jaws, and the second welding strip positioning component 38 can also be a welding strip clamping mechanism including a plurality of side-by-side clamping jaws. The first welding strip positioning component 37 clamps a welding strip to position the welding strip through each clamping jaw at the front section of the corresponding welding strip segment, and the second welding strip positioning component 38 clamps a welding strip to position the welding strip through each clamping jaw at the rear section of the corresponding welding strip segment.

[0067] Preferably, the first welding strip positioning component 37 is installed on the mounting frame 31 so that the distance between the first welding strip positioning component 37 and the tool picking mechanism 35 is adjustable. Figure 3 As shown, a connecting column mounting bracket 311 is provided on the mounting frame 31, and two clamping plates are provided on the connecting column mounting bracket 311. A transverse connecting column 39 is provided on the first welding strip positioning component 37. When the connecting column 39 is located between the two clamping plates, bolts can be used to pass through the two clamping plates to fasten it, so that the connecting column 39 is clamped between the two clamping plates. When the bolts are loosened, the position of the connecting column 39 extending between the two clamping plates can be adjusted, so as to adjust the distance between the first welding strip positioning component 37 and the tooling picking mechanism 35.

[0068] In this embodiment, the solder strip cutting mechanism 36 is arranged on the same mounting frame 31 on the side of the second solder strip positioning component 38 away from the tooling picking mechanism 35. In this way, after the second solder strip positioning component 38 positions the solder strip, the solder strip cutting mechanism 36 can conveniently cut the solder strip.

[0069] The specific structure of the welding strip cutting mechanism 36 is as follows Figure 3 and Figure 4As shown, the solder strip cutting mechanism 36 includes a cutting frame 363 installed on the mounting frame 31 and a first cutter 361 and a second cutter 362 installed on the cutting frame 363. The first cutter 361 is provided with a plurality of first blade portions arranged in a straight line, and the second cutter 362 is provided with a second blade portion corresponding to each first blade portion, and the first blade portion and the corresponding second blade portion are used to accommodate the solder strip to be cut.

[0070] Among them, Figure 6 As shown, the cutter frame 363 includes two long strips of plates, which clamp the first cutter 361 and the second cutter 362 and fasten them together using fasteners that pass through the two plates and the two cutters. Figure 7 As shown, the first cutter 361 and the second cutter 362 are provided with a transversely extending elongated hole 3612, and the fastener passes through the elongated hole 3612 to connect with the two outer elongated plates. The first cutter 361 and the second cutter 362 can move laterally relative to each other along the elongated hole 3612 to cut the welding strip.

[0071] The solder strip cutting mechanism 36 further includes a driving component, which drives the first cutter 361 and the second cutter 362 to move relative to each other so that the first blade portion and the corresponding second blade portion move away from each other to accommodate the solder strip to be cut and move toward each other to shear the solder strip.

[0072] Preferably, if Figure 6 and Figure 7 As shown, the driving component includes a first driving block 3611 provided on the first cutter 361, a second driving block 3621 provided on the second cutter 362, and a driving cylinder 364;

[0073] The driving rod 3641 of the driving cylinder 364 is configured to drive the first driving block 3611 and the second driving block 3621 to separate when inserted downwardly between the first driving block 3611 and the second driving block 3621 so as to make the first cutter 361 and the second cutter 362 move relative to each other;

[0074] A spring (not shown in the figure) is also arranged between the first driving block 3611 and the second driving block 3621. The spring applies an elastic force to the first driving block 3611 and the second driving block 3621 to move toward each other. When the driving rod 3641 is set to move upward, the spring drives the first driving block 3611 and the second driving block 3621 to move toward each other, thereby pulling the first cutter 361 and the second cutter 362 to move, so that each pair of blade portions are closed to achieve shearing of the welding strip, or each pair of blade portions are opened to accommodate the welding strip.

[0075] Furthermore, the welding strip cutting mechanism 36 also includes a cylinder mounting plate 365, which is fixed relative to the cutting frame 363, and the driving cylinder 364 is installed on the cylinder mounting plate 365, and the driving rod 3641 of the driving cylinder 364 is configured to extend downward between the first driving block 3611 and the second driving block 3621.

[0076] Preferably, a guide rod 366 is provided between the mounting frame 31 and the cutting frame 363, and the cutting frame 363 can move relative to the mounting frame 31 along the guide rod 366;

[0077] A spring is provided between the mounting frame 31 and the cutter frame 363 to apply a downward elastic force to the cutter frame 363, thereby maintaining the downward trend of the first cutter 361 and the second cutter 362. One end of the guide rod 366 is connected to the cutter frame 363, and the other end is movably inserted into the guide rod mounting frame 312 provided on the mounting frame 31.

[0078] The second welding strip positioning component 38 is fixed relative to the cutting frame 363 , that is, the second welding strip positioning component 38 is lifted and lowered together with the cutting frame 363 .

[0079] In this embodiment, if Figure 5 As shown, the end of the first welding strip positioning component 37 is provided with a protrusion for supporting the structure below to prevent the first cutter 361 and the second cutter 362 from contacting the battery sheet below. Figure 5 A first protrusion 371 shown in FIG.

[0080] The end of the second welding strip positioning component 38 is provided with a protrusion for supporting the structure below to prevent the first cutter 361 and the second cutter 362 from contacting the battery sheet below. Figure 5 The second protrusion 381 is shown in FIG.

[0081] After the welding strip cutting mechanism 36 cuts the welding strip, when the welding strip cutting mechanism 36 continues to move downward, the protrusions on the first welding strip positioning component 37 and the second welding strip positioning component 38 first contact the structure below, and are usually set to contact the end position of the supporting component 200 below, so that there is a gap between the first cutter 361 and the second cutter 362 and the battery cell below, which can prevent the first cutter 361 and the second cutter 362 from moving downward to contact the battery cell below and cause damage to the battery cell.

[0082] In this embodiment, the tool picking mechanism 35 includes a mounting plate 351 mounted on the mounting frame 31, and an electromagnet 352 capable of adsorbing and pressing the tool is provided on the mounting plate 351. When the electromagnet 352 is powered on, the pressing tool can be adsorbed, and when the adsorbed pressing tool needs to be released on the welding strip, the electromagnet 352 is powered off.
