[0052] a rack 100;

[0053] a roller 200 rotatably arranged on the rack 100; and

[0054] The pressure roller assembly 300 is arranged on the frame 100 and comprises a pressure roller 310, a first driving assembly 320, a second driving assembly 330 and a third driving assembly 340. The pressure roller 310 has a gap between the pressure roller 310 and the passing roller 200 for the passage of the tab.

The second driving assembly 330 drives the first driving assembly 320 to rotate to adjust the angle of the pressure roller 310. The third driving assembly 340 is drivingly connected to the second driving assembly 330 to adjust the distance between the pressure roller 310 and the passing roller 200.

[0055] The utility model discloses a technical scheme, and the reinforcing rib forming device 10 includes frame 100, sets up and passes through the roller 200 and the compression roller subassembly 300 on frame 100, and the lug passes through the roller 200 and the compression roller subassembly 300, and the reinforcing rib 301 is formed on the lug in the way of roller pressure, and the formation of reinforcing rib 301 increases the rigidity and the bending resistance of lug, reduces the risk such as lug fold, wrinkle or breakage in the process of battery assembly and use, improves the overall mechanical reliability of battery, specifically, the compression roller subassembly 300 includes compression roller 310, and the surface of compression roller 310 has specific recess or pattern, and the recess can be linear, wavy or other shape, depends on the required reinforcing rib 301 type, and the parallelism between compression roller 310 and the roller 200 is adjusted by setting first drive assembly 320 and driving compression roller 310 to move, that is, the distance between the both ends of compression roller 310 and the roller 200, and the distance between the end of compression roller 310 and the roller 200 is closer, and the depth of reinforcing rib 301 is deeper, and the height on both sides of compression roller 310 is adjusted through first drive assembly 320, so that compression roller 310 is parallel with the roller 200, to adjust the depth on both sides of reinforcing rib 301, satisfies the requirement that the depth on both sides of reinforcing rib 301 is same, improves the uniformity and consistency of lug reinforcing rib 301, or according to the process requirement, the depth on both sides of reinforcing rib 301 is adjusted to be different, to satisfy the requirement such as needing to deepen the indentation at the root or the outside, then the distance between one end of compression roller 310 and the roller 200 is close, and the distance between one end and the roller 200 is far through first drive assembly 320, and then the depth of reinforcing rib 301 on both sides is different, in addition, second drive assembly 330 is arranged and is driven to connect first drive assembly 320 to drive first drive assembly 320 to rotate in the horizontal direction, that is, drives compression roller 310 to rotate in the horizontal direction, to adjust the angle of compression roller 310 in the horizontal direction, to change the angle of reinforcing rib 301 to form other shapes of reinforcing rib 301 without replacing compression roller 310, and the compression roller subassembly 300 also includes third drive assembly 340, and third drive assembly 340 is driven to connect second drive assembly 330 to drive second drive assembly 330 to approach or be far from the roller 200, that is, adjusts the distance between the whole compression roller 310 and the roller 200, and the distance gap can make the lug pass through, and can make certain pressure exist between compression roller 310 and the roller 200, is convenient for forming reinforcing rib 301 on the lug by roller pressure, and the distance between compression roller 310 and the roller 200 is adjusted through third drive assembly 340, to adjust the depth of the whole indentation formed.

[0056] The two ends of the passing roller 200 are installed on the rack 100 through bearings and are rotationally connected with the rack 100 to reduce friction. The pressing roller 310 is usually made of hard material such as steel or hard alloy, which is not limited here, to avoid deformation under high pressure and affect the formation of the reinforcing rib 301. Grooves or grooves or patterns corresponding to the shape of the required reinforcing rib 301 are provided on the outer periphery of the pressing roller 310, and different teeth can be replaced according to different pole pieces 30 or processes. The distance between the pressing roller 310 and the passing roller 200 is adjusted by the third driving assembly 340, so that the lug can pass between the pressing roller 310 and the passing roller 200, and the passing roller 200 bears the pressure of the pressing roller 310 during the rolling process. The pressing roller 310 moves towards and contacts the passing roller 200 under the drive of the third driving assembly 340, so that the lug of the pole piece 30 is extruded to form a reinforcing rib 301 of a specific shape under the action of the forming pressing roller 310. The third driving assembly 340 can adopt a gas cylinder, and the pressure of the gas cylinder is adjusted by a pressure regulating valve to adjust the distance between the pressing roller 310 and the passing roller 200 and the depth of the indentation formed by the pressing roller 310. The third driving assembly 340 can also be replaced by other driving components such as motors, motors or hydraulic cylinders, and the structure of the third driving assembly 340 is not limited. The parallelism between the pressing roller 310 and the passing roller 200, i.e. the distance between the two ends of the pressing roller 310 and the passing roller 200, is adjusted by the first driving assembly 320. Since the pressing roller 310 and the passing roller 200 cannot be completely parallel during actual installation, it is easy to cause the extrusion depth of the lug reinforcing rib 301 to be too large on both sides, while the process requires the depth of the lug reinforcing rib 301 on both sides to be consistent. Therefore, the first driving assembly 320 is used to adjust the pressing roller 310 to be parallel to the passing roller 200, so that the depth of the lug reinforcing rib 301 on both sides is the same. Please refer to Figure 7 When the depth of the lug reinforcing rib 301 on both sides needs to be adjusted according to the requirements of the pole piece 30 or the process, such as the root being easily deformed and needing to deepen the indentation, the indentation depth of the root reinforcing rib 301 can be deepened and the indentation depth of the top reinforcing rib 301 can be shallowed, i.e. the depth of the lug reinforcing rib 301 on both sides is different. Please refer to Figure 8 and Figure 9 The second driving assembly 330 is provided to adjust the angle of the pressing roller 310. Without changing the pressing roller 310 and the pattern, the angle of the reinforcing rib 301 can be changed, as shown in Figure 1 and Figure 7 At this time, the pressing roller 310 is completely parallel to the passing roller 200, and the grooves on the pressing roller 310 are straight lines, corresponding to the straight reinforcing rib 301. As shown in Figure 6 , the pressing roller 310 is rotated to make the reinforcing rib 301 inclined, as shown in Figure 10 . That is, by adjusting the angle of the pressing roller 310 and the parallelism between the pressing roller 310 and the passing roller 200, the cost can be reduced.

[0064] The first driving assembly 320 further comprises a clamping block 322 and a first rotating shaft 324, the clamping block 322 is installed on one side of the mounting seat 321, and one end of the first rotating shaft 324 is connected with the clamping block 322; when it is needed to adjust the one end of the compression roller 310 to be close to the passing roller 200, the corresponding first linear pusher 323 pushes the compression roller 310, at this time, the compression roller seat 350 rotates relative to the mounting seat 321 with the first rotating shaft 324 as the center, thereby driving the other end of the compression roller 310 to rise away from the passing roller 200, and the depth of the two sides of the reinforcing rib 301 is adjusted; specifically, the first rotating shaft 324 has various installation modes, which are not limited here, for example, one end of the first rotating shaft 324 is rotatably connected with the clamping block 322 through a bearing, and the other end is connected with an installation plate (not shown) through a bearing, the installation plate is fixedly connected with the compression roller seat 350; or the two ends of the first rotating shaft 324 are respectively connected with a clamping block 322 through a bearing, the clamping blocks 322 are fixedly connected with the mounting seat 321, and the body of the first rotating shaft 324 penetrates through the compression roller seat 350, so that the compression roller seat 350 can rotate relative to the first rotating shaft 324, or the clamping blocks 322 are respectively arranged at the two ends of the first rotating shaft 324, the clamping blocks 322 are fixedly connected with the mounting seat 321, a through hole is arranged on the clamping block 322, the first rotating shaft 324 penetrates through the through hole and is connected with the clamping block 322, and the outer periphery of the first rotating shaft 324 is connected with the compression roller seat 350, the compression roller seat 350 can rotate with the length direction of the first rotating shaft 324 as the axis by rotating the first rotating shaft 324 in the through hole, although the friction is large, the compression roller seat 350 can rotate with the length direction of the first rotating shaft 324 as the axis, and the connection modes of the first rotating shaft 324 are not listed one by one here, as long as the compression roller seat 350 can rotate with the first rotating shaft 324 as the axis.

[0065] In the embodiment of the utility model, second driving assembly 330 includes:

[0066] Second rotating shaft, two ends are rotatably connected with the output end of third driving assembly 340 and mounting seat 321 respectively;

[0067] Second linear pusher 331, set two, two second linear pusher 331 set up along the opposite sides of mounting seat 321 in second direction, and exert the force in second direction to mounting seat 321 to make mounting seat 321 rotate around second rotating shaft;

[0068] Wherein, the first direction is perpendicular to the second direction.

[0069] Please refer to Figure 5The second driving assembly 330 comprises second linear pushers 331 which are arranged at two sides of the mounting seat 321 along the second direction, and the two second linear pushers 331 apply forces in opposite directions, for pushing the mounting seat 321 to move along the second direction. The third driving assembly 340 comprises a third linear pusher 342 and a connecting plate 341, and the third linear pusher 342 drives the connecting plate 341 to move up and down. Since a second rotating shaft (not shown) is arranged in the middle of the mounting seat 321, the other end of the second rotating shaft is connected with the connecting plate 341, that is, when the second linear pusher 331 applies a force in the second direction to the mounting seat 321, the actual mounting seat 321 rotates around the second rotating shaft as the axis to adjust the angle of the mounting seat 321, and then to adjust the angle of the compression roller 310, as shown in Figure 9 The groove of the compression roller 310 is still linear and parallel to the axis of the compression roller 310, but the extruded reinforcing rib 301 is in an inclined state, that is, the reinforcing rib 301 in different shapes can be realized without changing the compression roller 310.

Two threaded holes are arranged on the mounting seat 321 along the first direction at intervals. Each first adjusting screw passes through a threaded hole on the mounting seat 321 and is in threaded connection with the threaded hole. When the compression roller 310 is not parallel to the passing roller 200, and the process requires the depth of the reinforcing rib 301 on both sides to be the same, the parallelism of the compression roller 310 needs to be adjusted to ensure that it is parallel to the passing roller 200. The end of the compression roller 310 away from the passing roller 200 is provided with a corresponding first adjusting screw. The first adjusting screw is screwed to move close to the passing roller 200 to drive the compression roller seat 350 to move towards the passing roller 200. The other end of the compression roller 310 is closer to the passing roller 200. At this time, the corresponding first adjusting screw at the end is rotated to move away from the passing roller 200, so that the compression roller seat 350 rotates around the first rotating shaft 324 as the center to adjust to the parallel state with the passing roller 200.

[0071] In another embodiment, the second driving assembly 330 further comprises a support seat 332 connected to the connecting plate 341.

Please refer to Figure 5The support base 332 is arranged at one end of the third driving assembly 340 output end close to the end of the mounting base 321, and extends along the second direction. The second straight pushing piece 331 is configured as a second adjusting screw. Two second adjusting screws are arranged at two ends of the support base 332 and abut against the end of the mounting base 321 through the support base 322. Specifically, the support base 332 is provided with a threaded hole. The second adjusting screw is screwed with the support base 332 and abuts against the end of the mounting base 321. That is, by screwing the adjusting screw, the end of the mounting base 321 connected with the second adjusting screw has a tendency to move along the second direction. Since the middle of the mounting base 321 is rotationally connected with the connecting plate 341 through the second rotating shaft, the mounting base 321 rotates and drives the compression roller 310 to rotate and adjust the angle, thereby changing the angle of the reinforcing rib 301.

The tab reinforcing rib forming device 10 further comprises an adjusting assembly 400 arranged on the rack 100 and drivingly connected with the compression roller assembly 300 to adjust the distance between the two compression roller assemblies 300. The roller 200 extends along the length direction of the rack 100, and each compression roller assembly 300 is matched with the roller 200. That is, when the pole piece 30 passes between the compression roller assembly 300 and the roller 200, the two compression roller assemblies 300 can simultaneously process the tabs at both ends of the pole piece 30, that is, the formation of the reinforcing rib 301 is completed by one-time extrusion, which simplifies the production process and improves the production efficiency. In addition, the distance between the two compression roller assemblies 300 can be changed by the adjusting assembly 400 to adapt to pole pieces 30 of different specifications and different widths, thereby improving the versatility and applicability of the device.
