Figure 2 A three-dimensional diagram of a portion of the folding mechanism provided in one embodiment of the present application. Figure 3 This is an orthographic projection view of a portion of the folding mechanism provided in one embodiment of the present application. Figure 4Another orthographic projection view of a portion of the folding mechanism provided in one embodiment of the present application. Figure 5 A diagram of a usage state of the folding mechanism provided in one embodiment of the present application. Figure 6 This is another use state diagram of the folding mechanism provided in one embodiment of the present application. Figures 1 to 6 The folding mechanism provided in the embodiment of the present application includes a base body 1, a folding assembly 2, a flip connector 3, and a lifting drive assembly 4.

[0054] The seat body 1 is the main structure of the folding mechanism.

[0055] The folding assembly 2 is used to fold and press the workpiece by turning over. The folding assembly 2 is arranged on the seat body 1 and can rotate relative to the seat body 1. The folding assembly 2 can be connected to the seat body 1 through a pin shaft to achieve rotation relative to the seat body 1.

[0056] The folding assembly 2 has an active opening 210. The active opening 210 can be a groove or a notch.

[0057] The flip connector 3 is used to connect the folding assembly 2 to the lifting drive assembly 4 .

[0058] The flip connector 3 includes a flip body 30 and a first contact portion 31 .

[0059] The first contact portion 31 is connected to the flip body 30 . The first contact portion 31 abuts against the wall surface of the movable opening 210 of the folding assembly 2 and can move relative to the folding assembly 2 at the movable opening 210 .

[0060] The first contact portion 31 may be a rotating component that can rotate relative to the flip body 30 . Thus, the friction between the first contact portion 31 and the wall of the movable opening 210 is rolling friction, which can make the first contact portion 31 move more smoothly in the movable opening 210 .

[0061] For example, the first contact portion 31 may be a cam follower, a roller or a bearing, wherein the cam follower can withstand a larger load.

[0062] In some other embodiments, the first contact portion 31 is a component fixed relative to the flip body 30 .

[0063] The lifting drive assembly 4 is connected to the flip body 30 to drive the flip connector 3 to move along the lifting direction H, thereby driving the folding assembly 2 to rotate relative to the base 1. The lifting direction H can be a vertical direction or a height direction of the folding mechanism.

[0064] The lifting drive assembly 4 can specifically be a cylinder, a linear motor or a screw nut assembly.

[0065] The lifting drive assembly 4 drives the flip joint 3 to move along the lifting direction H, and the first contact portion 31 of the flip connector 3 abuts against the wall of the movable opening 210 of the folding assembly 2. The first contact portion 31 pushes the folding assembly 2 along the lifting direction H and moves relative to the folding assembly 2 in the movable opening 210, so that the folding assembly 2 rotates relative to the seat body 1, and the edge 101 of the workpiece 100 is folded (specifically, the edge 101 of the workpiece 100 can be folded into an L shape or a V shape), which can withstand a large load and improve the load bearing capacity of the entire mechanism. The lifting drive assembly 4 drives the flip joint 3 to move in the opposite direction of the lifting direction H, which can reset the folding assembly 2 and complete the whole set of actions.

[0066] By setting the stroke of the lifting drive assembly 4 and the size of the movable opening 210 , the rotation angle of the folding assembly 2 relative to the base body 1 can be controlled.

[0067] Figure 7 A three-dimensional diagram of a rotating connection component of a folding mechanism provided in an embodiment of the present application. Figure 7 The folding assembly 2 may include a rotating connecting component 21 and a folding head 22 .

[0068] The rotating connection component 21 is disposed on the base body 1 and can rotate relative to the base body 1 .

[0069] The movable opening 210 is located on the rotating connecting component 21 .

[0070] The folding head 22 is disposed on the rotating connecting component 21 to rotate relative to the base body 1 along with the rotating connecting component 21 .

[0071] refer to Figure 2 The folding head 22 may include a pushing component 221 and a blocking component 222 .

[0072] The pushing component 221 is detachably disposed on the rotating connecting component 21 and can be suitable for folding workpieces of various sizes.

[0073] The blocking member 222 is provided on the pressing member 221 .

[0074] The folding head 22 may be an L-shaped structure or a contour-like structure; wherein the contour-like structure of the folding head 22 is determined according to the shape of the part of the workpiece to be folded.

[0075] By pushing the workpiece by the pushing component 221 and blocking the workpiece by the blocking component 222 , the workpiece can be folded into a target shape (such as an L-shape) more accurately.

[0076] The number of the movable openings 210 may be two, and the number of the first contact portions 31 may be two.

[0077] refer to Figure 2 and Figure 7 The rotating connection component 21 may include a connection arm 219 , a first movable connection part 211 , and a second movable connection part 212 .

[0078] The connecting arm 219 is connected to the folding head 22 .

[0079] The first movable connection portion 211 is connected to the connection arm 219 and is rotatably disposed on the base body 1 . A movable opening 210 is located at the first movable connection portion 211 .

[0080] The second movable connection portion 212 is connected to the connection arm 219 and is rotatably disposed on the base body 1 . The other movable opening 210 is located at the second movable connection portion 212 .

[0081] One first contact portion 31 abuts against the movable opening 210 of the first movable connection part 211, and the other first contact portion 31 abuts against the movable opening 210 of the second movable connection part 212, which can ensure that the flip connector 3 stably drives the folding component 2 to fold, and can improve the folding accuracy.

[0082] refer to Figures 2 to 4 The above-mentioned flip connector 3 may also include a second contact portion 32.

[0083] The second contact portion 32 is connected to the flip body 30 and abuts against the base 1 to move along the lifting direction H with the flip body 30 and move relative to the base 1 .

[0084] refer to Figures 2 to 4 The seat body 1 may include a frame 11 and a limiting component 12 .

[0085] The limiting component 12 is disposed on the frame 11 .

[0086] The second contact portion 32 abuts against the limiting component 12 and can move along the lifting direction H relative to the limiting component 12 .

[0087] The second contact portion 32 may be a rotating component that can rotate relative to the flip body 30 . In this way, the friction between the second contact portion 32 and the surface of the limiting component 12 is rolling friction, which can make the movement of the second contact portion 32 smoother.

[0088] For example, the second contact portion 32 may be a cam follower, a roller, or a bearing, wherein the cam follower can withstand a larger load.

[0089] refer to Figure 5 The folding mechanism may further include a guide sleeve 5.

[0090] The guide sleeve 5 is disposed on the seat body 1 .

[0091] The lifting drive assembly 4 may include a moving rod 41 and a lifting drive body 42 .

[0092] The moving rod 41 is passed through the guide sleeve 5 and connected to the flip connector 3 .

[0093] The lifting driving body 42 is connected to the moving rod 41 to drive the moving rod 41 to move along the lifting direction H relative to the guide sleeve 5 .

[0094] The limiting component 12, the second contact portion 32 and the guide sleeve 5 can provide a large supporting force for the lifting drive assembly 4, and can effectively prevent the overturning force generated when folding a large workpiece from causing damage to the folding mechanism.

[0095] refer to Figure 1 The folding mechanism may further include a placement table 6.

[0096] The placement table 6 is used to place the workpiece.

[0097] The placement table 6 is disposed on the base 1 , so that the folding assembly 2 can rotate relative to the base 1 to approach the placement table 6 to fold at least a portion of the workpiece (such as folding the edge of the workpiece).

[0098] The working principle of the folding mechanism provided in the embodiment of the present application is as follows:

[0099] Place a workpiece (such as a soft-pack battery) on the placement table 6, and fix the workpiece on the placement table 6 (for example, fix the workpiece on the placement table 6 by other clamping mechanisms); under the action of the lifting drive body 42 of the lifting drive assembly 4, the flip connector 3 is lifted up and down by the moving rod 41; during the lifting process, under the protection of the limiting component 12, the second contact portion 32 and the guide sleeve 5, the folding assembly 2 is flipped relative to the seat body 1 around the pin shaft, and the aluminum-plastic film of the soft-pack battery is folded to fold the edge of the aluminum-plastic film of the soft-pack battery by 90°; the aluminum-plastic film can be folded 180° by bending through other mechanisms, so that the burr edge of the aluminum-plastic film is folded to the middle section, making the edge smooth, which can effectively prevent the batteries from damaging each other during the series-parallel process and effectively ensure the safety and stability of the batteries.

[0100] The folding mechanism provided in the embodiment of the present application can complete the folding of workpieces of different sizes, can withstand a large overturning force, and has good stability.

[0101] An embodiment of the present application provides a battery production device, which includes the folding mechanism provided by any of the above embodiments.

[0102] The folding mechanism provided in the embodiment of the present application can be used to fold the aluminum-plastic film of a soft-pack battery, which can prevent the burrs generated by the cut edges of the soft-pack battery from piercing the battery cell and causing battery leakage and short circuit, thereby protecting the soft-pack battery and increasing the safety and stability of battery production and use.
