Description

Technical Field

[0001] This invention relates to the field of production and manufacturing equipment technology for new energy lithium batteries, and specifically to an automatic bending device. Background Technology

[0002] With the increasing global demand for environmental protection and renewable energy, new energy batteries, with their efficient and clean energy storage methods, have enormous market demand and development potential, and the manufacturing output of lithium batteries continues to grow. New energy lithium batteries typically use a flexible connection to connect the battery cover and the cell, with the flexible connection structure serving as the conductive component between the two.

[0003] In the manufacturing process of new energy lithium batteries, ultrasonic welding is mainly used to connect the flexible connector of the battery cover to the electrode tab. However, this welding process requires manual bending of the flexible connector into a specific shape to ensure its correct alignment with the electrode tab. This bending method is inefficient and cannot guarantee the accuracy of bending, easily resulting in incomplete bending, affecting the welding quality, and even causing phenomena such as the flexible connector not covering the electrode tab or bending at the corner of the flexible connector. Based on this, some manufacturers have tried to improve the above bending process by using semi-automation or automation methods, such as configuring a vision system to identify the position and orientation of the connecting piece. Although this ensures the accuracy of bending, it also increases the production cost and maintenance difficulty. Summary of the Invention

[0004] This invention provides an automatic bending device to solve the problems of high cost and difficult maintenance of existing automatic bending devices.

[0005] To solve the above-mentioned technical problems, the present invention provides an automatic bending device, which includes: a feeding area, a synchronous transfer mechanism, a pre-bent part, and a bent part.

[0006] The feeding area is provided with a first gripper; the synchronous transfer mechanism is provided with a plurality of transfer components for transferring the battery cover plate at intervals along the first direction, the first gripper being used to grip the battery cover plate to the transfer component, wherein the battery cover plate has a first flexible connecting piece and a second flexible connecting piece protruding along the second direction.

[0007] The pre-bent component is provided with a suction cup portion facing the transfer component, which can contact the first flexible connecting piece and the second flexible connecting piece, so that the first flexible connecting piece and the second flexible connecting piece are in an open shape.

[0008] The pre-bent component and the bending component are arranged sequentially along the first direction. The bending component is provided with a bending push plate, which is capable of bending the first flexible connecting piece and the second flexible connecting piece along the opening of the first flexible connecting piece and the second flexible connecting piece.

[0009] The beneficial effects of the technical solution provided by this invention compared to the prior art are as follows:

[0010] The battery cover is automatically placed into the transfer component by the first gripper in the feeding area. The transfer component is located in the synchronous transfer mechanism, which can cooperate with the gripper to achieve fast and precise transfer of the battery cover. The pre-bent component and the bent component for performing the bending step are arranged sequentially along the first direction, so that when the synchronous transfer mechanism moves synchronously, the pre-bent component and the bent component can sequentially work on the first and second flexible connecting pieces located on the transfer component. That is, by setting the working gap of the first gripper, the pre-bent component and the bent component, and adjusting the moving trajectory and speed of the transfer mechanism to transfer the workpiece, the fully automated bending operation can be effectively ensured.

[0011] Furthermore, the pre-bending process uses a suction cup to pick up the first and second flexible connecting pieces, opening them from their original stacked state. This allows the bending pusher to push the first and second flexible connecting pieces along the opening to bend them to a set angle. Compared to the current method of directly bending them, adding a pre-bending component effectively improves bending accuracy and reduces the error rate of bending operations, thereby significantly improving production efficiency and bending quality.

[0012] In some embodiments, the automatic bending device further includes a first detection component located between the pre-bent piece and the feeding area along the first direction, and used to detect the height of the first flexible connecting piece and the second flexible connecting piece; wherein the pre-bent piece is provided with a positive height avoidance cylinder and a negative height avoidance cylinder that are communicatively connected to the first detection component.

[0013] By adopting the above technical solution, a first detection component is set up to detect the current height of the first and second flexible connecting pieces, thereby ensuring that the pre-bent part and the bending part can be aligned with the first and second flexible connecting pieces for operation. Furthermore, the pre-bent part is equipped with a positive height avoidance cylinder and a negative height avoidance cylinder that are communicatively connected to the first detection component, thereby adjusting the height of each component of the pre-bent part (e.g., a suction cup push baffle or a positive angle push plate) in a timely manner to avoid collisions or damage to the first and second flexible connecting pieces.

[0014] In some embodiments, the pre-bending component further includes a suction cup pushing baffle and a positive electrode angle pushing plate. The suction cup pushing baffle is spaced apart from the suction cup portion along the first direction and can abut against the second flexible connecting piece. The positive electrode angle pushing plate is located at the bottom of the positive electrode height avoidance cylinder along the second direction and is used to push the first flexible connecting piece.

[0015] Using the above technical solution, the suction cup push assembly is used to ensure the vacuum level of the suction cup part to pick up the second flexible connector piece; while the positive angle push plate can cooperate with the suction cup part to ensure the vacuum level when the second flexible connector piece performs the pre-bending step, and can also ensure the correctness and consistency of the angle of the first flexible connector piece, which is convenient for subsequent welding.

[0016] In some embodiments, the bending member is further provided with a movable cylinder, which is used to drive the bending push plate to tilt and displace at a set angle along the first direction.

[0017] Using the above technical solution, a bending pusher is used at a set angle to facilitate its insertion into the openings of the first and second flexible connecting pieces, and to perform the bending step. The movable cylinder can adjust the displacement length of the bending pusher, thereby adjusting the bending angle of the first and second flexible connecting pieces.

[0018] In some embodiments, the automatic bending device further includes a first transfer mechanism, which includes a lateral movement module and a lifting module. The lateral movement module extends along the first direction and is connected to the lifting module, enabling the lifting module to move along the lateral movement module. The lifting module also includes a flipping module at its bottom along the second direction. The flipping module is connected to the first gripper and is used to drive the first gripper to rotate clockwise or counterclockwise.

[0019] Using the above technical solution, the first transfer mechanism cooperates with the first gripper to automatically place the battery cover onto the transported component. Specifically, after the lifting module moves along the transverse module to the battery cover gripping point (e.g., the material tray), it moves downward so that the first gripper located below the lifting module can grip the battery cover; after the first gripper grips the battery cover, the lifting module moves upward and along the transverse module to the bending loading position, while the first gripper rotates under the action of the flipping module; the lifting module moves downward again so that the first gripper can correctly place the battery cover onto the transported component. The above actions are performed synchronously with the synchronous transfer mechanism to realize the placement of the battery cover onto the transported component at the corresponding workstation.

[0020] In some implementations, the first transfer mechanism further includes a tray transfer mechanism, which is equipped with a vacuum suction cup and a transverse cylinder connected to the vacuum suction cup. The transverse cylinder is used to drive the vacuum suction cup to move in a third direction.

[0021] Using the above technical solution, when the vacuum suction cup is moved to the position of the material tray under the drive of the transverse cylinder, the lifting module can drive the vacuum suction cup to move down so that the vacuum suction cup contacts the material tray and picks up the material tray. The transverse cylinder then drives the vacuum suction cup to move to the area where the first gripper can pick up the material, thereby further realizing a fully automated production process and improving production efficiency.

[0022] In some embodiments, the automatic bending equipment further includes a unloading area spaced apart from the loading area along the first direction, the unloading area being provided with a second gripper and a second transfer mechanism for clamping the battery cover away from the transport member.

[0023] The above technical solution includes a loading area and a unloading area to further automate the production process. The second gripper in the unloading area can cooperate with a synchronous transfer mechanism to automatically remove the bent battery cover. The second gripper and the second transfer mechanism are symmetrically arranged with the first gripper and the first transfer mechanism.

[0024] In some implementations, the synchronous transplanting mechanism is further provided with second detection components on both sides along a third direction. The second detection components are used to detect the bending angle of the first flexible connecting piece and the second flexible connecting piece after the bending component is bent.

[0025] By adopting the above technical solution, a second detection component for detecting bending angle is added, which makes it easier for staff to detect and adjust the bending angle of the first and second flexible connecting pieces in a timely manner. It can also be combined with deep learning to automatically learn and adjust the bending force and bending angle of the bent parts.

[0026] In some embodiments, the automatic bending equipment further includes an ultrasonic welding module located along the first direction on the side of the bent part away from the pre-bent part.

[0027] By adopting the above technical solution, ultrasonic welding function is integrated so that bending and welding operations can be completed successively on the same processing line, thereby improving the processing efficiency of battery cover plates.

[0028] In some implementations, the feeding area is further provided with a conveying mechanism and a buffer platform. The conveying mechanism is connected to the buffer platform and is used to convey material trays. The buffer platform is provided with a material tray transfer module above it along the second direction.

[0029] Using the above technical solution, since the number of battery covers that can be placed in a single tray is limited, a slow tray movement rhythm can easily affect the production process when the loading and unloading cycle is too fast. Therefore, adding a transmission mechanism and a buffer platform can effectively ensure the operating rhythm of the fully automatic bending equipment. Attached Figure Description

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0045] See Figures 1 to 4 As shown, Figure 1 A top view of an embodiment of an automatic bending device provided in this application is shown; Figure 2 A partial three-dimensional structural diagram of an embodiment of an automatic bending device provided in this application is shown. Figure 1 ; Figure 3 This application provides a three-dimensional structural schematic diagram of an embodiment of a pre-bending component 30 of an automatic bending device. Figure 1 ; Figure 4 A three-dimensional structural schematic diagram of an embodiment of a bending component 40 of an automatic bending device provided in this application is shown.

[0046] In some implementations, the automatic bending equipment includes: a feeding area 10, a synchronous transfer mechanism 20, a pre-bent part 30, and a bent part 40.

[0047] The feeding area 10 is equipped with a first gripper 11; the synchronous transfer mechanism 20 moves along a first direction ( Figure 1 (As shown in the X direction) Multiple transfer members 21 for transferring the battery cover 80 are arranged at intervals. The first gripper 11 is used to grip the battery cover 80 to the transfer member 21. The battery cover 80 has a direction along the second direction (as shown in the X direction). Figure 8 (As shown in the Z direction) The first flexible connecting piece 81 and the second flexible connecting piece 82 are protruding.

[0048] The pre-bent member 30 is provided with a suction cup portion 31 facing the transfer member 21, which can contact the first flexible connecting piece 81 and the second flexible connecting piece 82, so that the first flexible connecting piece 81 and the second flexible connecting piece 82 are open. The pre-bent member 30 and the bending member 40 are along the first direction ( Figure 1(As shown in the X direction) are arranged sequentially, wherein the bending member 40 is provided with a bending push plate 41, which can bend the first flexible connecting piece 81 and the second flexible connecting piece 82 along the opening of the first flexible connecting piece 81 and the second flexible connecting piece 82.

[0049] In this embodiment, the battery cover plate 80 is automatically placed into the transfer member 21 by the first gripper 11 of the loading area 10. The transfer member 21 is located in the synchronous transfer mechanism 20, enabling the synchronous transfer mechanism 20 to cooperate with the first gripper 11 to achieve rapid and accurate transfer of the battery cover plate 80. This application does not limit the type of the first gripper 11; the gripper can adjust its clamping force according to different specifications or shapes of the battery cover plate 80, for example, a parallel gripper consisting of two parallel gripper arms clamping in opposite directions. For example, a tray is set to carry 24 battery cover plates 80, and the cycle time of the first gripper 11 retrieving material from the tray is 0.5 hours.

[0050] Combination Figure 2 As shown, the pre-bent part 30 and the bent part 40 used to perform the bending step are along the first direction ( Figure 1 As shown in the X direction, the components are arranged sequentially so that when the synchronous transfer mechanism 20 moves synchronously, the pre-bent parts 30 and the bent parts 40 can sequentially work on the first flexible connecting piece 81 and the second flexible connecting piece 82 located on the transfer piece 21. That is, by setting the working gap of the first gripper 11, the pre-bent parts 30 and the bent parts 40, and adjusting the moving trajectory and speed of the transfer mechanism to transport the workpiece, the fully automated bending operation can be effectively ensured. For example, the synchronous transfer mechanism 20 can move the transfer piece 21 to adjust to different work positions for operation. Among them, a fixed frame 22 is set above the synchronous transfer mechanism 20, and multiple pre-bent parts 30 and multiple bent parts 40 are arranged along a third direction (X direction). Figure 8 (As shown in the Y direction) are spaced apart on the fixing frame 22 and oriented towards the transfer member 21. For example Figure 2 The row of six transport components 21 shown has three workstations, and three pre-bent components 30 and three bent components 40 are correspondingly provided. Furthermore, this application does not limit the number of the aforementioned components; for example, it can be set to five workstations, six workstations, etc., depending on the production scale.

[0051] In addition, combined Figure 3 and Figure 4 As shown, the pre-bending uses the suction cup 31 to pick up the first flexible connecting piece 81 and the second flexible connecting piece 82, so that the first flexible connecting piece 81 and the second flexible connecting piece 82, which were originally in a stacked state, can be opened (see...). Figure 6This facilitates the bending pusher plate 41 to push the first flexible connecting piece 81 and the second flexible connecting piece 82 along the opening to bend them to a set angle. Compared with the current method of directly bending them, adding a pre-bending part 30 can effectively improve the bending accuracy and reduce the error rate of bending actions, thereby greatly improving production efficiency and bending quality.

[0052] In some implementations, the automatic bending device also includes a first direction ( Figure 1 (As shown in the X direction) The unloading area 70 is spaced apart from the loading area 10. The unloading area 70 is provided with a second gripper 71 and a second transfer mechanism 72 for clamping the battery cover 80 away from the transfer member 21.

[0053] In this embodiment, a loading area 10 and a unloading area 70 are provided to further automate the production process. The second gripper 71 of the unloading area 70 can cooperate with the synchronous transfer mechanism 20 to automatically remove the bent battery cover 80. The second gripper 71 and the second transfer mechanism 72 are symmetrically arranged with the first gripper 11 and the first transfer mechanism 60.

[0054] Combination Figure 5 and Figure 6 As shown, Figure 5 This application provides a three-dimensional structural schematic diagram of an embodiment of a pre-bending component 30 of an automatic bending device. Figure 2 ; Figure 6 This application provides a three-dimensional structural schematic diagram of an embodiment of a battery cover plate 80 of an automatic bending device. Figure 1 Among them, the first flexible connecting piece 81 and the second flexible connecting piece 82 are in an open state.

[0055] In some implementation schemes, combined Figure 2 and Figure 5 As shown, the automatic bending equipment also includes a first detection component 50, which is positioned along a first direction ( Figure 1 (As shown in the X direction) is located between the pre-bent part 30 and the feeding area 10, and is used to detect the height of the first flexible connecting piece 81 and the second flexible connecting piece 82; wherein, the pre-bent part 30 is provided with a positive height avoidance cylinder and a negative height avoidance cylinder that are communicatively connected to the first detection component 50.

[0056] In this embodiment, a first detection component 50 is provided to detect the current height of the first flexible connecting piece 81 and the second flexible connecting piece 82, thereby ensuring that the pre-bent member 30 and the bent member 40 can be aligned with the first flexible connecting piece 81 and the second flexible connecting piece 82 for operation. Exemplarily, the number of first detection components 50 is equal to the number of workstations set in the same row and column of the synchronous transfer mechanism 20.

[0057] In some embodiments, the pre-bent member 30 further includes a suction cup push baffle 34 and a positive angle push plate 35, the suction cup push baffle 34 being along a first direction ( Figure 1 (As shown in the X direction) and the suction cup portion 31 are spaced apart and can abut against the second flexible connecting piece 82; wherein, the positive electrode angle pushing plate 35 is along the second direction ( Figure 8 (As shown in the Z direction) is located at the bottom of the positive electrode height avoidance cylinder, and the positive electrode angle push plate 35 is used to push the first soft connecting piece 81.

[0058] In this embodiment, the pre-bent component 30 is equipped with a positive electrode height avoidance cylinder and a negative electrode height avoidance cylinder that are communicatively connected to the first detection component 50, thereby adjusting the height of each component of the pre-bent component 30 in a timely manner to avoid collision or damage to the first flexible connecting piece 81 and the second flexible connecting piece 82; for example, the negative electrode height avoidance cylinder drives the suction cup to push the baffle 34 up or down according to the detection result of the first detection component 50; the positive electrode height avoidance cylinder drives the positive electrode angle pushing plate 35 up or down according to the detection structure of the first detection component 50.

[0059] For example, the suction cup portion 31 also includes a movable cylinder 4236, which can drive the suction cup to move closer to or away from the first flexible connecting piece 81 or the second flexible connecting piece 82. Specifically, when the suction cup pulls away the second flexible connecting piece 82, the positive angle push plate 35 can simultaneously push the first flexible connecting piece 81.

[0060] The suction cup pushing assembly ensures the vacuum level for the suction cup section 31 to pick up the second flexible connector 82. For example, when the suction cup section 31 picks up the second flexible connector 82, the pushing plate of the suction cup pushing assembly abuts against the second flexible connector 82, allowing the suction cup to smoothly open the second flexible connector 82. The positive angle pushing plate 35 not only cooperates with the suction cup section 31 to ensure the vacuum level when the second flexible connector 82 undergoes the pre-bending step, but also ensures the correctness and consistency of the angle of the first flexible connector 81, facilitating subsequent welding.

[0061] For example, the automatic bending equipment also includes an ultrasonic welding module (not shown in the figure), the ultrasonic welding module being positioned along a first direction ( Figure 1 (As shown in the X direction) Located on the side of the bent part 40 away from the pre-bent part 30. Integrated ultrasonic welding function allows bending and welding operations to be completed sequentially on the same processing line, thereby improving the processing efficiency of the battery cover 80.

[0062] In some implementations, the synchronous transplanting mechanism 20 is along a third direction ( Figure 8 A second detection component is also provided on both sides of the bending part 40 (shown in the Y direction). The second detection component is used to detect the bending angle of the first flexible connecting piece 81 and the second flexible connecting piece 82 after bending.

[0063] In this embodiment, by adding a second detection component for detecting bending angles, it is easier for workers to promptly detect and adjust the bending angles of the first flexible connecting piece 81 and the second flexible connecting piece 82. It can also be combined with deep learning to automatically learn and adjust the bending force and bending angle of the bending component 40. Exemplarily, the second detection component can be a laser measuring device, an optical detection device, or other detection equipment; this application does not limit its use.

[0064] Combination Figure 7 As shown, Figure 7 This application provides a three-dimensional structural schematic diagram of an embodiment of a battery cover plate 80 of an automatic bending device. Figure 2 Among them, the first flexible connecting piece 81 and the second flexible connecting piece 82 are in a bent state.

[0065] In some implementation schemes, combined Figure 4 As shown, the bending component 40 is also equipped with a moving cylinder 4236, which is used to drive the bending pusher 41 along a first direction ( Figure 1 (As shown in the X direction) Tilting angle displacement setting.

[0066] In this embodiment, a bending pusher 41 is used at a set angle to facilitate its insertion into the openings of the first flexible connecting piece 81 and the second flexible connecting piece 82, and to perform the bending step. The movable cylinder 4236 can adjust the displacement length of the bending pusher 41, thereby adjusting the bending angle of the first flexible connecting piece 81 and the second flexible connecting piece 82, for example, bending from 90° to 95°.

[0067] See Figures 8 to 9 As shown, Figure 8 This application provides a three-dimensional structural schematic diagram of an embodiment of the first transfer mechanism 60 of an automatic bending device. Figure 1 ; Figure 9 This application provides a schematic diagram of the layout and three-dimensional structure of an automatic bending device. Figure 2 .

[0068] In some embodiments, the automatic bending equipment further includes a first transfer mechanism 60, which includes a lateral movement module 61 and a lifting module 62, the lateral movement module 61 moving along a first direction ( Figure 1 Extending in the X direction (as shown in the middle) and connected to the lifting module 62, so that the lifting module 62 can be displaced along the transverse module 61; wherein, the lifting module 62 extends along the second direction (as shown in the middle X direction) and is connected to the lifting module 62, so that the lifting module 62 can be displaced along the transverse module 61; wherein, the lifting module 62 extends in the second direction (as shown in the middle X direction) Figure 8 The bottom of the (shown in the Z direction) is also provided with a flipping module 63, which is connected to the first gripper 11 and is used to drive the first gripper 11 to rotate in a clockwise or counterclockwise direction.

[0069] In this embodiment, the first transfer mechanism 60 cooperates with the first gripper 11 to automatically place the battery cover 80 onto the transfer member 21. Exemplarily, after the lifting module 62 moves along the transverse module 61 to the material handling area, for example... Figure 9 The buffer area stores the battery cover plate 80 in the tray; it moves downward so that the first gripper 11 located below the lifting module 62 can grasp the battery cover plate 80; after the first gripper 11 grasps the battery cover plate 80, the lifting module 62 moves upward and moves along the transverse module 61 to the bending loading position, that is Figure 9 At the synchronous transfer mechanism 20 shown, the first gripper 11 rotates under the action of the flipping module 63; the lifting module 62 moves down again so that the first gripper 11 can correctly place the battery cover 80 on the transfer component 21. The above actions are performed synchronously with the synchronous transfer mechanism 20 to realize the placement of the battery cover 80 on the transfer component 21 of the corresponding workstation.

[0070] In some implementations, the feeding area 10 is further provided with a conveying mechanism 12 and a buffer platform 13. The conveying mechanism 12 is connected to the buffer platform 13 and is used to convey the material tray, wherein the buffer platform 13 is along the second direction ( Figure 8 A material transfer module is located above the Z-axis (as shown in the middle Z direction).

[0071] In this embodiment, since the number of battery cover plates 80 that can be placed in a single tray is limited, a slow tray movement rhythm can easily affect the production process when the loading and unloading cycle is too fast. Therefore, adding a transmission mechanism 12 and a buffer platform 13 can effectively ensure the operating rhythm of the fully automatic bending equipment.

[0072] For example, see Figure 1 As shown, the transmission mechanism 12 transmits the tray containing the battery cover plate 80 along direction B, and transmits the empty tray after the first gripper 11 has removed the material along direction A. The transmission mode can be set so that the transmission mechanism 12 starts transmitting when a set of empty trays (e.g., 10 trays as a set) is stored; or it can be set to start continuously, transmitting whenever the tray is empty.

[0073] In some embodiments, the first transfer mechanism 60 further includes a tray transfer mechanism 64, which is equipped with a vacuum suction cup 640 and a transverse cylinder 641 connected to the vacuum suction cup 640. The transverse cylinder 641 is used to drive the vacuum suction cup 640 along a third direction. Figure 8 Displacement in the Y direction (as shown in the middle).

[0074] In this embodiment, when the vacuum suction cup 640 is moved to the position of the material tray under the drive of the transverse cylinder 641, the lifting module 62 can drive the vacuum suction cup 640 to move down so that the vacuum suction cup 640 contacts the material tray and picks up the material tray. The transverse cylinder 641 then drives the vacuum suction cup 640 to move to the area where the first gripper 11 can pick up the material, thereby further realizing a fully automated production process and improving production efficiency.

[0075] For example, after the material picking area is empty, the vacuum suction cup 640 transfers the empty material tray to the buffer platform. The buffer platform 13 may be equipped with an automatic lifting device to reduce the material tray transfer mechanism 64 moving along the second direction (…). Figure 8 The journey is shown in the Z direction.
