Figure 1 As shown, this application discloses a bending device 10, which includes a main unit 20 and a collector plate bending device 50. The main unit 20 controls the operation of the collector plate bending device 50, and the main unit 20 includes devices such as a computer.
[0040] This application also discloses a manifold bending device 50, which can be used in the bending equipment 10 described above. Regarding the manifold bending device 50, this application provides the following design:
[0041] Figure 2 This is a schematic diagram of a manifold bending device according to an embodiment of this application. Figure 3 This is a schematic diagram of a battery according to an embodiment of this application, as shown below. Figure 2-3 As shown, this application discloses a current collector bending device 50, which is used to bend the current collector 40 on the battery 30. The current collector 40 includes a welding part 41, a connecting part 42 and a current collector body part 43 connected in sequence. The welding part 41 is welded to the end of the battery 30.
[0042] The collector plate bending device 50 includes a lifting component 100, a first bending component 200, and a second bending component 300. The lifting component 100 and the second bending component 300 are disposed opposite to each other, and the first bending component 200 is located between the second bending component 300 and the lifting component 100. The lifting component 100 is used to fix the battery 30.
[0043] The first bending component 200 includes a first bending main frame 210, a first bending blade assembly 220, and a first pressing blade assembly 230. The first bending blade assembly 220 is connected to the first bending main frame 210 and can move up and down.

[0044] The second bending component 300 includes a second bending main frame 310, a second bending blade assembly 320, and a second pressing blade assembly 330. The second bending blade assembly 320 is connected to the second bending main frame 310 and can move up and down. The second pressing blade assembly 330 is connected to the second bending main frame 310 and can move up and down. The second bending blade assembly 320 is located below the second pressing blade assembly 330.
[0045] During the bending process, the second bending blade assembly 320 moves downward to abut against the front side of the connecting part 42, and the first pressing blade assembly 230 moves upward to abut against the back side of the connecting part 42, so as to bend the welding part 41 and the connecting part 42; the first pressing blade assembly 230 moves downward, the first bending blade assembly 220 moves upward to abut against the back side of the connecting part 42, and the second pressing blade assembly 330 moves downward to abut against the collector plate main body 43, so as to bend the connecting part 42 and the collector plate main body 43.
[0046] In simple terms, the second folding blade assembly 320 and the first pressing blade assembly 230 move to bend the welding part 41 and the connecting part 42, so that the welding part 41 and the connecting part 42 form an angle; then the first folding blade assembly 220 and the second pressing blade assembly 330 move to bend the connecting part 42 and the main body part 43 of the collector plate, so that the connecting part 42 and the main body part 43 of the collector plate form an angle, so that the collector plate 40 finally forms a Z-shaped shape.
[0047] Compared to the existing method of manually bending the collector plate 40, this application uses a lifting component 100, a first bending component 200, and a second bending component 300 working together. When bending the collector plate 40, the second bending blade assembly 320 moves downward to abut against the front of the connecting part 42, and the first pressing blade assembly 230 moves upward to abut against the back of the connecting part 42, thereby bending the welded part 41 and the connecting part 42. The first pressing blade assembly 230 moves downward, the first bending blade assembly 220 moves upward to abut against the back of the connecting part 42, and the second pressing blade assembly 330 moves downward to abut against the collector plate body 43, thereby bending the connecting part 42 and the collector plate body 43. The collector plate bending device 50 of this application has a simpler and more reliable structure, which can improve production efficiency and reduce production costs. Moreover, the method of using the collector plate bending device 50 will not cause uneven force on the collector plate 40 during bending, thus avoiding damage to the collector plate 40.
[0048] like Figure 4 As shown, the first folding knife assembly 220 includes a first folding knife lifting assembly 221 and a first folding knife 222. The first folding knife lifting assembly 221 is fixed on the first bending main frame 210. The first folding knife 222 is connected to the first folding knife lifting assembly 221. The first folding knife lifting assembly 221 drives the first folding knife 222 to move up and down.
[0049] The first pressing knife assembly 230 includes a first pressing knife lifting assembly 231 and a first pressing knife 232. The first pressing knife lifting assembly 231 is fixed on the first bending main frame 210. The first pressing knife 232 is connected to the first pressing knife lifting assembly 231. The first pressing knife lifting assembly 231 drives the first pressing knife 232 to move up and down.
[0050] like Figure 5 As shown, the second folding knife assembly 320 includes a second folding knife lifting assembly 321 and a second folding knife 322. The second folding knife lifting assembly 321 is fixed on the second bending main frame 310. The second folding knife 322 is connected to the second folding knife lifting assembly 321. The second folding knife lifting assembly 321 drives the second folding knife 322 to move up and down.
[0051] The second pressing knife assembly 330 includes a second pressing knife lifting assembly 331 and a second pressing knife 332. The second pressing knife lifting assembly 331 is fixed on the second bending main frame 310. The second pressing knife 332 is connected to the second pressing knife lifting assembly 331. The second pressing knife lifting assembly 331 drives the second pressing knife 332 to move up and down.
[0052] Specifically, the second folding blade 322 is driven downward by the second folding blade lifting assembly 321, and the first pressing blade 232 is driven upward by the first pressing blade lifting assembly 231, thereby bending the welding part 41 and the connecting part 42 so that the welding part 41 and the connecting part 42 form an angle; the first folding blade 222 is driven upward by the first folding blade lifting assembly 221, and the second pressing blade 332 is driven downward by the second pressing blade lifting assembly 331, bending the connecting part 42 and the main body part 43 of the collecting plate so that the connecting part 42 and the main body part 43 of the collecting plate form an angle.
[0053] like Figure 6 As shown, the second pressing knife 332 includes a pressing knife crossbar 341, a connecting shaft 342, and a pressing wheel 343. One end of the pressing knife crossbar 341 is connected to the second pressing knife lifting assembly 331, and the other end is connected to the connecting shaft 342. The connecting shaft 342 is connected to the pressing wheel 343, and the pressing wheel 343 and the connecting shaft 342 can rotate coaxially.
[0054] In simple terms, the second pressing blade 332 uses a roller to roll the main body 43 of the collector plate, which can reduce the friction between the second pressing blade 332 and the main body 43 of the collector plate and avoid damage to the main body 43 of the collector plate.
[0055] Furthermore, since a protrusion is provided on the side of the collector plate main body 43 opposite to the battery 30, the pressure roller 343 includes a first sub-pressure roller 344 and a second sub-pressure roller 345. The connecting shaft 342, the first sub-pressure roller 344, and the second sub-pressure roller 345 can rotate coaxially. A gap is provided between the first sub-pressure roller 344 and the second sub-pressure roller 345, the length of which is greater than the length of the protrusion, to prevent the first sub-pressure roller 344 and the second sub-pressure roller 345 from squeezing against the protrusion on the collector plate main body 43. This avoids damage to the collector plate 40 when bending it, thereby improving production yield.
[0056] Figure 7 This is a schematic diagram of a lifting component according to an embodiment of this application, as shown below. Figure 7 As shown, the collector plate bending device 50 also includes a conveyor belt 400, which is located between the second bending component 300 and the lifting component 100.
[0057] The lifting component 100 includes a lifting main frame 110, a fixing clamp lifting assembly 120, a fixing clamp retracting assembly 130, and a fixing clamp assembly 140. The fixing clamp assembly 140 is connected to the fixing clamp retracting assembly 130, and the fixing clamp retracting assembly 130 is used to control the opening and closing of the fixing clamp assembly 140. One end of the fixing clamp lifting assembly 120 is connected to the lifting main frame 110, and the other end is connected to the fixing clamp retracting assembly 130. The fixing clamp lifting assembly 120 is used to control the up and down movement of the fixing clamp retracting assembly 130, thereby driving the fixing clamp assembly 140 to move up and down.
[0058] Specifically, the conveyor belt 400 transports the battery 30 with the collector plate 40 to be bent to the area below the fixing clamp assembly 140. The collector plate 40 on the battery 30 faces the second bending device. The fixing clamp assembly 140 is controlled by the fixing clamp retracting assembly 130 to open and retract to clamp the battery 30. The fixing clamp lifting assembly 120 controls the fixing clamp retracting assembly 130 to move up and down, thereby driving the fixing clamp assembly 140 to move upward to the target position.
[0059] like Figure 8 As shown, the fixing clamp assembly 140 includes a first fixing jaw 141 and a second fixing jaw 142. Both the first fixing jaw 141 and the second fixing jaw 142 are connected to the fixing clamp retracting assembly 130. The fixing clamp retracting assembly 130 controls the first fixing jaw 141 and the second fixing jaw 142 to move away from each other or towards each other. The side of the first fixing jaw 141 facing the second fixing jaw 142 is arc-shaped, and the side of the second fixing jaw 142 facing the first fixing jaw 141 is arc-shaped.
[0060] In simple terms, the opposite sides of the first fixing claw 141 and the second fixing claw 142 are both set to be arc-shaped, which can better match the shape of the battery 30, thereby firmly clamping the battery 30 without damaging the battery 30 body.
[0061] Figure 9 This is a schematic diagram of a corrective component according to an embodiment of this application, as shown below. Figure 9 As shown, the manifold bending device 50 also includes a straightening component 500, which is connected to the second bending main frame 310.

One end of the corrective clamp translation assembly 510 is connected to the second bending main frame 310, and the other end is connected to the corrective clamp retraction assembly 520. The corrective clamp translation assembly 510 is used to control the left and right translational movement of the corrective clamp retraction assembly 520, thereby driving the corrective clamp assembly 530 to move left and right.
[0063] The straightening fixture translation assembly 510 controls the left and right translation movement of the straightening fixture retraction assembly 520, thereby driving the straightening fixture assembly 530 to translate left and right, so that the straightening fixture assembly 530 is close to the battery 30 on the conveyor belt 400. The straightening fixture retraction assembly 520 controls the opening and closing of the straightening fixture assembly 530 to straighten the collector plate 40, so as to avoid the battery 30 with the collector plate 40 tilting, which would damage the collector plate 40 during subsequent bending.
[0064] The specific bending steps of the collector plate 40 include: Step 1: The battery 30 with the collector plate 40 to be bent is transported to the bottom of the fixing clamp assembly 140 via the conveyor belt 400; Step 2: The straightening component 500 straightens the battery 30 of the collector plate 40 to ensure that the collector plate is not angularly skewed; Step 3: The fixing clamp lifting assembly 120 controls the fixing clamp retracting assembly 130 to move downward, thereby driving the fixing clamp assembly 140 downward onto the conveyor belt 400. The fixing clamp retracting assembly 130 controls the fixing clamp assembly 140 to open and retract to clamp the battery 30, and the fixing clamp lifting assembly 120 controls the fixing clamp retracting assembly 130 to move upward, thereby driving the fixing clamp assembly 140 upward to the target position; Step 4: The second folding blade 322 is driven downward by the second folding blade lifting assembly 321, and the second folding blade 322 is driven downward by the second folding blade lifting assembly 321 to move downward. The first pressing knife lifting assembly 231 drives the first pressing knife 232 to move upward. The second folding knife 322 and the first pressing knife 232 respectively abut against the upper and lower sides of the connecting part 42, thereby bending the welding part 41 and the connecting part 42, so that the welding part 41 and the connecting part 42 form an angle. Fifth step: The first pressing knife lifting assembly 231 drives the first pressing knife 232 to move downward, the first folding knife lifting assembly 221 drives the first folding knife 222 to move upward, and the second pressing knife lifting assembly 331 drives the second pressing knife 332 to move downward. The first folding knife 222 abuts against the intersection of the connecting part 42 and the main body of the collector plate 43, bending the connecting part 42 and the main body of the collector plate 43, so that the connecting part 42 and the main body of the collector plate 43 form an angle, completing the bending process of the collector plate 40 on the battery 30.
