Abstract
Description
Technical Field
[0001] This application relates to the field of battery technology, and more specifically, to a bending and rolling device and production equipment. Background Technology
[0002] Solid-state batteries are a new generation of high-performance, green, and high-energy batteries, characterized by high voltage, high capacity, low power consumption, no memory effect, no pollution, small size, low internal resistance, low self-discharge, and high cycle life. They are widely used in automotive power batteries, mobile phones, laptops, tablets, and many other consumer applications.
[0003] In related technologies, during the assembly process of solid-state batteries, the tabs need to be welded to the busbar. Before welding, the tabs need to be bent and rolled in a specified order to ensure that the tabs fit the busbar. Therefore, designing a bending and rolling structure is particularly important. Utility Model Content
[0004] The purpose of this application is to provide a bending and rolling device and production equipment that can perform bending and rolling processes.
[0005] In a first aspect, embodiments of this application provide a bending and flattening device, comprising: a rotating assembly including a rotating member and a connecting member, the rotating member being connected to the connecting member for driving the connecting member to rotate; and a processing assembly including a bending structure and a flattening structure, the bending structure and the flattening structure being connected to the connecting member; wherein the rotating member adjusts the bending structure and the flattening structure to a side closer to the tab via the connecting member, the bending structure being used to bend the tab, and the flattening structure being used to flatten the bent tab.
[0006] In the above process, the bending structure and the rolling structure are set on the connector, and the connector is connected to the rotating component. This allows the rotating component to rotate the bending structure and the rolling structure according to the position of the electrode tab, so as to meet the bending and rolling requirements of the electrode tab in different positions.

[0008] In the above implementation process, the bending head is used to bend the electrode tab, and the bending head is set on the first slide cylinder. The first slide cylinder can be used to buffer when the bending head contacts the electrode tab, so as to avoid the bending head directly contacting the electrode tab hard, which would cause damage to the electrode tab and improve the yield of the electrode tab.
[0009] In some embodiments, the flattening structure includes a flattening head and a second slide cylinder, wherein the flattening head is connected to the second slide cylinder, and the second slide cylinder is connected to the flattening head.
[0010] In the above process, the flattening head is used to flatten the tabs. The flattening head is set on the second slide cylinder. The second slide cylinder can be used to buffer when the flattening head contacts the tab, avoiding direct hard contact between the flattening head and the tab, which would damage the tab and improve the yield of the tab.
[0011] In some embodiments, the bending head and the rolling head are disposed on the same side of the connector. This allows for simultaneous bending and rolling of the tabs, achieving higher precision. Furthermore, by adjusting the positions of the bending head and the rolling head through a rotating assembly, bending and rolling of tabs at different locations can be performed, saving on equipment costs and space requirements, and improving the yield rate of tab bending and rolling.

[0013] In some embodiments, the ranging structure includes a ranging element. This allows for the measurement of the distance between the electrodes, which is beneficial for the control system to control the movement of the bending and rolling structures.
[0014] In some embodiments, the ranging structure further includes a video camera. The video camera is used to photograph the electrode tabs and transmit the information to the control system for processing, facilitating the control of the movement of the bending and rolling structures.

The connecting frame is provided with the bending structure and the rolling structure, so that when the servo motor is driven, the bending structure and the rolling structure rotate around the central axis of the output shaft. This allows the bending structure and the rolling structure to be integrated into a single structure, facilitating the simultaneous rotation of the bending structure and the rolling structure by the rotating assembly. This is beneficial for bending and rolling tabs at different positions, improving the applicability of the device and reducing costs.
[0016] In some embodiments, the bending and rolling device further includes a drive component connected to the rotating component for driving the rotating component to move along a preset direction.
[0017] In the above process, the drive component is connected to the rotating component. The drive component can drive the rotating component to move to a specified position according to the size of the product, which can realize the bending and flattening of the tabs of different products, thus improving the applicability of the device.
[0018] In some embodiments, the driving component includes a first driving structure, a second driving structure, and a third driving structure. The first driving structure is connected to the second driving structure to drive the second driving structure to move along a first direction. The second driving structure is connected to the third driving structure to drive the third driving structure to move along a second direction. The third driving structure is connected to the rotating component to drive the rotating component to move along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other.
[0019] In some embodiments, the drive assembly further includes a mounting bracket that connects the first drive structure, the second drive structure, and the third drive structure.
[0020] Secondly, this application also provides a production apparatus, including a bending and rolling device as described in any of the preceding claims.
[0021] In the above process, the bending structure and the rolling structure are set on the connector, and the connector is connected to the rotating component. This allows the rotating component to rotate the bending structure and the rolling structure according to the position of the electrode tab, so as to meet the bending and rolling requirements of the electrode tab in different positions.

[0034] Example
[0035] All-solid-state batteries require high pressure to be applied through isostatic pressure technology to enhance interfacial bonding. Pouch packaging can withstand higher pressure and maintain structural integrity. All-solid-state batteries use non-flammable solid electrolytes, which are safer than liquid batteries. Pouch packaging does not require a winding structure, further reducing the risk of internal short circuits. The removal of liquid electrolyte reduces the necessity of hard-shell packaging, making pouch packaging an ideal carrier for all-solid-state batteries. Currently, pouch packaging is the main route for all-solid-state batteries.
[0036] All-solid-state battery modules mainly consist of pouch cells, nanoplatelets, and casings. Busbars and cell tabs are typically welded together using different series and parallel connection methods to meet the process requirements of various products. Before welding, the tabs need to be bent and rolled in a specified order to ensure proper fit between the tabs and the busbar, thus guaranteeing welding quality. Therefore, the bending and rolling techniques are highly demanding. During R&D, to verify different solutions, all-solid-state batteries with side-mounted tabs and top-mounted tabs are commonly used. These two structures typically require two dedicated machines for bending and rolling, resulting in high costs and limited space.
[0037] Firstly, such as Figures 1-2 As shown, this application provides a bending and flattening device, including: a rotating component 1, including a rotating member 101 and a connecting member 102, wherein the rotating member 101 is connected to the connecting member 102 and is used to drive the connecting member 102 to rotate; and a processing component 2, including a bending structure and a flattening structure, wherein the bending structure and the flattening structure are connected to the connecting member 102; wherein the rotating member 101 adjusts the bending structure and the flattening structure to the side closer to the electrode tab through the connecting member 102, the bending structure is used to bend the electrode tab, and the flattening structure is used to flatten the bent electrode tab.
[0038] For example, the bending and rolling device is used for bending and rolling the tabs of batteries, where the batteries include all-solid-state batteries (soft-pack cells). When assembling all-solid-state batteries into battery modules, the tabs of the all-solid-state batteries need to be bent and rolled in a specified order to ensure that the tabs fit with the busbars, ensure welding quality, and realize series and parallel connections between all-solid-state batteries.
[0039] The rotating component 1 is a part used to drive the processing component 2 to rotate. The rotating component 101 includes a servo motor, and the connecting component 102 includes a gearbox. The main working principle is based on the meshing transmission of gears. When the input shaft drives a gear to rotate, the teeth of the gear mesh with the teeth of the adjacent gear, thereby causing the adjacent gear to rotate. Finally, the output shaft outputs torque. The rotating component 101 is connected to the connecting component 102 and can be used to drive the connecting component 102 to rotate around its own center to meet the requirements of all-solid-state batteries with side-out tabs (e.g., tabs located on the left and right sides of the battery) and top-out tabs (e.g., tabs located at the top of the battery). The bending structure and the rolling structure are both set in the rotating component 1, so that when the rotating component 1 is working, the processing component 2 can be adjusted to the left and right sides of the battery and to the top of the battery to meet the requirements of different battery tab outlet methods.
[0040] In the above implementation process, the bending structure and the rolling structure are set on the connector 102, and the connector 102 is connected to the rotating member 101, so that the rotating member 101 can rotate the bending structure and the rolling structure according to the position of the electrode tab, so as to meet the bending and rolling requirements of the electrode tab at different positions, save the cost of the device and save the space occupied, and improve the yield of electrode tab bending and rolling.
[0041] like Figure 2 As shown, the bending structure includes a bending head 201 and a first slide cylinder 202. The bending head 201 is connected to the first slide cylinder 202, and the first slide cylinder 202 is connected to the connector 102. For example, the bending head 201 is connected to the first slide cylinder 202. Through the action of the first slide cylinder 202, it can be used to absorb the force generated by movement in the Z direction.
[0042] In the above implementation process, the bending head 201 is used to bend the electrode tab. The bending head 201 is set on the first slide cylinder 202. The first slide cylinder 202 can be used to buffer when the bending head 201 contacts the electrode tab, so as to avoid the bending head 201 directly contacting the electrode tab hard, which would damage the electrode tab and improve the yield of the electrode tab.
[0043] like Figure 2As shown, the rolling structure includes a rolling head 203 and a second slide cylinder 204. The rolling head 203 is connected to the second slide cylinder 204, and the second slide cylinder 204 is connected to the rolling head 203. For example, the rolling head 203 is connected to the second slide cylinder 204, and the second slide cylinder 204 is closer to the connector 102 than the first slide cylinder 202. Through the action of the second slide cylinder 204, it can be used to absorb the force generated by movement in the Z direction (up and down direction).
[0044] In the above process, the flattening head 203 is used to flatten the tab. The flattening head 203 is set on the second slide cylinder 204. The second slide cylinder 204 can be used to buffer when the flattening head 203 contacts the tab, so as to avoid the flattening head 203 directly contacting the tab hard, which would damage the tab and improve the yield of the tab.
[0045] In some embodiments, the bending head 201 and the rolling head 203 are disposed on the same side of the connector 102. This allows for simultaneous bending and rolling of the electrode tabs with higher precision. Furthermore, by adjusting the positions of the bending head 201 and the rolling head 203 using the rotating assembly 1, bending and rolling of electrode tabs at different locations can be achieved, saving on equipment costs and space requirements, and improving the yield rate of electrode tab bending and rolling.
[0046] In some embodiments, the processing component 2 further includes a ranging structure connected to the connector 102. This allows for photographic ranging of the electrode's position and feedback of the electrode's position information to the control system. This facilitates the movement of the bending and rolling structures to designated positions, improves accuracy, avoids damage to the electrode, and increases the electrode's yield.
[0047] like Figure 1 and Figure 2 As shown, the ranging structure includes a ranging element 205. Exemplarily, the ranging element 205 includes, but is not limited to, a laser rangefinder. Its main principle is to accurately measure the distance to a target using a parameter of a modulated laser. For example, a pulsed laser rangefinder emits a beam or a sequence of short pulsed laser beams towards the target during operation. A photoelectric element receives the laser beam reflected from the target, and a timer measures the time from emission to reception to calculate the distance from the rangefinder to the target. This allows for the measurement of the distance to the electrodes, which is beneficial for the control system to control the movement of the bending and rolling structures.
[0048] In some embodiments, the ranging structure further includes a video capture device 206, which includes, but is not limited to, a camera. The video capture device 206 is used to capture images of the electrode tabs and transmit this information to the control system for processing, facilitating the control of the movement of the bending structure and the rolling structure.
[0049] In some embodiments, the processing component 2 further includes a connecting frame 207, the rotating component 101 includes a servo motor, the connecting component 102 includes a gearbox, one end of the gearbox is connected to the output end of the servo motor, the other end of the gearbox is fitted to the connecting frame 207, and the output shaft of the gearbox is connected to the connecting frame 207. The connecting frame 207 is provided with the bending structure and the rolling structure, so that when the servo motor is driven, the bending structure and the rolling structure rotate around the central axis of the output shaft.
[0050] For example, the connecting frame 207 refers to the component used to connect the bending structure and the rolling structure. The bending head 201 of the bending structure and the rolling head 203 of the rolling structure are located on the same side of the connecting frame 207, and both the bending head 201 and the rolling head 203 are protruding relative to the connecting frame 207. The first slide cylinder 202 of the bending structure and the second slide cylinder 204 of the rolling structure are disposed inside the connecting frame 207, and the first slide cylinder 202 is further away from the connecting member 102 than the second slide cylinder 204.
[0051] It is understandable that the ranging structure is set on the connecting frame 207, and the ranging component 205 and the video capturing component 206 of the ranging structure are both set on the same side of the connecting frame 207.
[0052] In the above implementation process, the bending structure and the rolling structure can be integrated into the same structure, which facilitates the joint rotation of the bending structure and the rolling structure by the rotating component 1. This is beneficial for bending and rolling the tabs at different positions, improving the applicability of the device and reducing the cost.
[0053] In some embodiments, the bending and rolling device further includes a driving component 3, which is connected to the rotating component 1 and is used to drive the rotating component 1 to move along a preset direction, such as up and down, left and right, or front and back.
[0054] In the above process, the drive component 3 is connected to the rotating component 1. The drive component 3 can drive the rotating component 1 to move to a specified position according to the size of the product, which can realize the bending and flattening of the tabs of different products, thus improving the applicability of the device.
[0055] like Figure 1As shown, the driving component 3 includes a first driving structure 301, a second driving structure 302, and a third driving structure 303. The first driving structure 301 is connected to the second driving structure 302 and is used to drive the second driving structure 302 to move along a first direction. The second driving structure 302 is connected to the third driving structure 303 and is used to drive the third driving structure 303 to move along a second direction. The third driving structure 303 is connected to the rotating component 1 and is used to drive the rotating component 1 to move along a third direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other.
[0056] For example, the first drive structure 301 includes a first drive member and a first slide rail. The first drive member includes a servo motor. The second drive structure 302 is disposed on the first slide rail, which is distributed along a first direction, and the first drive member is connected to the second drive structure 302. The second drive structure 302 includes a second drive member and a second slide rail, which includes a servo motor. The third drive structure 303 is disposed on the second slide rail, which is distributed along a second direction, and the second drive member is connected to the third drive structure 303. The third drive structure 303 includes a third drive member and a third slide rail, which includes a servo motor. The rotating component 1 is disposed on the third slide rail, which is distributed along a third direction, and the third drive member is connected to the rotating component 1. The first direction includes the left-right direction, the second direction includes the front-back direction, and the third direction includes the up-down direction.
[0057] Please refer to again Figure 1 The drive assembly 3 further includes a mounting bracket 304, which connects the first drive structure 301, the second drive structure 302 and the third drive structure 303.
[0058] For example, the mounting bracket 304 includes a first bracket and a second bracket. The first bracket is connected to the second bracket. The first bracket is distributed along a first direction, and the second bracket is distributed along a second direction. There are two first brackets, which are located at the front and rear ends of the second bracket. The first bracket is provided with a first slide rail, and the second bracket is provided with a second slide rail.
[0059] Secondly, this application also provides a production equipment, including the bending and flattening device as described above. Exemplarily, the production equipment further includes a tooling fixture for carrying and clamping the all-solid-state battery module. The tooling fixture transports the all-solid-state battery module to the bending and flattening device. The bending and flattening device controls the movement of the bending structure and the flattening structure according to the position of the tabs in the all-solid-state battery module. Subsequently, the bending structure and the flattening structure perform bending and flattening operations on the tabs in a specific sequence to ensure that the tabs fit snugly against the busbar and to ensure welding quality.
[0060] Specifically, the drive component 3 moves the bending structure and the rolling structure to the designated position, the video capture unit 206 is rotated to the front of the electrode tab by the rotating component 1 to take a picture, and at the same time the ranging component 205 measures the distance and feeds the information back to the control system. Then the bending structure is rotated to the front of the electrode tab and the electrode tab is bent in sequence. The rolling structure is rotated to the front of the electrode tab by the rotating component 1 and the electrode tab is rolled in sequence.
[0061] In the above implementation process, the bending structure and the rolling structure are set on the connector 102, and the connector 102 is connected to the rotating member 101, so that the rotating member 101 can rotate the bending structure and the rolling structure according to the position of the electrode tab, so as to meet the bending and rolling requirements of the electrode tab at different positions, save the cost of the device and save the space occupied, and improve the yield of electrode tab bending and rolling.
