Description

Technical Field

[0001] This invention relates to the field of battery processing technology, and in particular to a battery casing processing equipment. Background Technology

[0002] Battery casing processing equipment is used to spin-cut battery casings to meet the dimensional requirements of subsequent processes. This type of equipment typically has a loading station, a spin-cutting station, and an unloading station. A material transfer device moves the battery casings between these stations, and the spin-cutting device processes the casings at the spin-cutting station.

[0003] Currently, in common processing equipment, the material handling device typically performs both conveying and positioning functions. After the conveying device transports the battery casing to the rotary cutting station, it must continuously lock the battery casing in position to prevent misalignment during the rotary cutting process and ensure processing quality. However, in the above structure, because the material handling device needs to continuously lock the battery casing during the rotary cutting process, it must wait until the rotary cutting is completed before releasing the battery casing and returning to the loading station to grab the next battery casing to be processed. The material handling device is idle and waiting during processing, resulting in low handling efficiency, a slow overall equipment operating cycle, and consequently, a decrease in production efficiency. Summary of the Invention

[0004] This invention provides a battery casing processing device to reduce the waiting time of the material transfer mechanism during battery casing processing, improve handling efficiency, and thus enhance overall production efficiency.

[0005] This invention discloses a battery casing processing equipment, comprising a loading station, a rotary cutting station, and a unloading station arranged sequentially along a first direction, and further comprising:

[0006] Machine tool; A material transfer mechanism is mounted on the machine platform. The material transfer mechanism includes a horizontal drive component, a lifting drive component, and multiple fixture groups. The multiple fixture groups are arranged along a first direction and are used to position the battery casing. The horizontal drive component and the lifting drive component are both connected to the fixture groups. The horizontal drive component is used to drive each fixture group to reciprocate synchronously between two adjacent workstations. The lifting drive component is used to drive each fixture group to lift synchronously, so that the fixture groups can pick up and put down the battery casing. A rotary cutting mechanism is mounted on the machine base and corresponds to the rotary cutting station. The rotary cutting mechanism includes a first rotary cutting component and a first fixing component. The first fixing component alternately cooperates with the fixture group on the rotary cutting station to remove the battery case to be processed when the fixture group is released from positioning, and to transfer the rotary-cut battery case to the fixture group. The first rotary cutting component cooperates with the first fixing component to rotary cut the battery case on the first fixing component.

[0007] In one embodiment, the material transfer mechanism further includes: A lifting frame is slidably connected to the machine base in a second direction, and the lifting frame is connected to the lifting drive component, wherein the second direction is perpendicular to the first direction; A connector is mounted on the lifting frame, and the connector extends in the first direction and slides with the lifting frame. The fixture is assembled on the connector, and the output end of the horizontal drive is connected to one end of the connector. When the lifting frame drives the connector to rise and fall, the horizontal drive can move with the connector.

[0008] In one embodiment, the horizontal drive component includes a push rod and a main body. The main body is used to drive the push rod to extend or retract. The push rod is connected to one end of the connector. The main body is rotatably mounted on the machine platform in a third direction so that when the lifting seat drives the connector to rise or fall, the main body can swing along with the connector. The third direction is perpendicular to the second direction and the first direction, respectively.

[0009] In one embodiment, a lifting mechanism is further included, which is disposed corresponding to the horizontal drive member, and is used to support the main body when the main body swings.

[0010] In one embodiment, when the fixture assembly secures the battery casing, the battery casing is exposed outside the fixture assembly at both ends in the third-party upward direction; The first fixing component includes a power source, a first fixing member, and a second fixing member. The first fixing member and the second fixing member are located on both sides of the fixture assembly in the third direction. The power source is connected to the first fixing member and the second fixing member and is used to drive the first fixing member and the second fixing member to move towards each other in the third direction, so that the first fixing member and the second fixing member respectively limit and fix the two ends of the battery case.

[0011] In one embodiment, the rotary cutting mechanism is connected to the power source. The first rotary cutting mechanism includes a rotary drive and a cutting tool. The cutting tool and the fixture assembly are arranged adjacent to each other in the third direction. When the first fixing member and the second fixing member fix the battery case, the cutting tool extends into the battery case. The rotary cutting drive is connected to the cutting tool and is used to drive the cutting tool to rotate so that the cutting tool can rotary cut the battery case.

[0012] In one embodiment, the rotary cutting station includes a primary rotary cutting station and a secondary rotary cutting station sequentially arranged in a first direction; The rotary cutting mechanism further includes a second rotary cutting component and a second fixing component. The first rotary cutting component and the first fixing component are disposed on the secondary rotary cutting position, and the second rotary component and the second fixing component are disposed on the initial rotary cutting position. The second fixing component alternately cooperates with the fixture group on the rotary cutting position to remove the battery shell to be processed from the fixture group and to put the rotary-cut battery shell back into the fixture group. The second rotary cutting component cooperates with the second fixing component to pre-cut the battery shell of the second fixing component.

[0013] In one embodiment, the system further includes a feeding mechanism mounted on the machine platform corresponding to the feeding station. The feeding mechanism includes a conveying component for conveying the rotary-cut battery casings. The conveying component has a clearance area on its side adjacent to the rotary-cutting mechanism, wherein the corresponding fixture assembly can move to the clearance area to transfer the rotary-cut battery casings in the fixture to the conveying component. Alternatively, the system further includes a feeding mechanism mounted on the machine platform corresponding to the feeding station. The feeding mechanism includes a storage component and a conveying component. The storage component stores the battery casings and supplies them to the feeding mechanism. The conveying component conveys the battery casings from the storage component to the fixture assembly at the feeding station.

[0014] In one embodiment, the battery casing processing equipment further includes a dust blowing station, which is located in the first direction between the rotary cutting station and the unloading station; it also includes a dust blowing mechanism, which is installed on the machine base and corresponds to the dust blowing station. The dust blowing mechanism includes a first limiting component and a dust blowing component. The first limiting component and the fixture group are arranged adjacent to each other in the third direction for picking up and placing the rotary-cut battery casings on the corresponding fixture group. The dust blowing component cooperates with the first limiting component to clean the dust from the rotary-cut battery casings. Alternatively, the battery casing processing equipment may also include a grinding station, which is located in the first direction between the rotary cutting station and the unloading station; it may also include a grinding mechanism, which is mounted on the machine base and corresponds to the grinding station. The grinding mechanism includes a second limiting component and a grinding component. The second limiting component and the fixture group are arranged adjacent to each other in the third direction for picking up and placing the rotary-cut battery casings on the corresponding fixture group. The grinding component cooperates with the second limiting component for grinding the surface of the rotary-cut battery casings.

[0015] In one embodiment, the battery casing processing equipment further includes a punching station, which is located in the first direction between the rotary cutting station and the unloading station; it also includes a punching mechanism, which is mounted on the machine base and corresponds to the punching station. The punching mechanism alternately cooperates with the fixture group on the punching station to adjust the position of the rotary-cut battery casing when the corresponding fixture group is released from positioning.

[0016] The beneficial effects of the battery casing processing equipment provided in this embodiment of the invention are as follows: the first fixing component and the corresponding fixture group in the material transfer mechanism can operate alternately, making the material transfer process faster and the processing efficiency higher, thereby improving production efficiency.

[0017] Specifically, the horizontal drive component transports the battery casing to be processed at the loading station to the swivel cutting station corresponding to the swivel cutting mechanism along a first direction. The first fixing component locks the battery casing to be processed when the transfer mechanism moves it to the swivel cutting station, thus releasing the corresponding fixture group in the transfer mechanism from positioning the battery casing at the swivel cutting station. Subsequently, the horizontal drive component cooperates with the lifting drive component to return each fixture group from the current station to the previous station, and each fixture group re-locks the battery casing at the loading station and the swivel cutting station. Simultaneously, the first swivel cutting component completes the swivel cutting of the battery casing, and the first fixing component unlocks the swivel-cut battery casing. The horizontal drive component can then quickly transfer each fixture group to the next station, allowing the swivel-cut battery casing to be transported to the unloading station, and the battery casing at the loading station to the swivel cutting station, restarting the cyclic processing. This demonstrates that the processing equipment has a shorter dwell time during material handling and can quickly complete unloading and reloading after the battery casing is rotary cut, resulting in higher processing efficiency and thus improving overall production efficiency.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] This invention provides a battery casing processing device 1000, such as... Figure 1 - Figure 2 As shown, there is a first direction (such as...) Figure 1 and Figure 2 The loading stations (as shown in the X direction) are set up in sequence (e.g., ... Figure 1 As shown in P1), rotary cutting station (such as...) Figure 1 (as shown in P2 and P3) and the unloading station (such as...) Figure 1 As shown on page 8, the battery casing processing equipment 1000 includes a machine base 100, a material transfer mechanism 200, and a rotary cutting mechanism 300. The material transfer mechanism 200 is mounted on the machine base 100 and includes a horizontal drive component 210, a lifting drive component 220, and multiple fixture groups 230. The multiple fixture groups 230 are arranged along a first direction and are used to position the battery casing 2000. The horizontal drive component 210 and the lifting drive component 220 are both connected to the fixture groups 230. The horizontal drive component 210 is used to drive each fixture group 230 to reciprocate synchronously between two adjacent workstations, and the lifting drive component 220 is used to drive each fixture group... The fixture assembly 230 is synchronously raised and lowered to allow it to pick up and place the battery casing 2000. The rotary cutting mechanism 300 is mounted on the machine base 100 and corresponds to the rotary cutting station. The rotary cutting mechanism 300 includes a first rotary cutting component 310 and a first fixing component 320. The first fixing component 320 alternately cooperates with the fixture assembly 230 at the rotary cutting station to remove the battery casing 2000 to be processed when the fixture assembly 230 is released from its position, and to transfer the rotary-cut battery casing 2000 to the fixture assembly 230. The first rotary cutting component 310 cooperates with the first fixing component 320 to rotary cut the battery casing 2000 on the first fixing component 320. In this application, the first fixing component 320 and the corresponding fixture assembly 230 in the transfer mechanism 200 can operate alternately, making the transfer process faster and the processing efficiency higher, thereby improving production efficiency.

[0022] Specifically, the horizontal drive component 210 can transport the battery casing 2000 to be processed at the loading station to the veneer cutting station corresponding to the veneer cutting mechanism 300 along the first direction. The first fixing component 320 can limit and lock the battery casing 2000 to be processed when the transfer mechanism 200 transfers the battery casing 2000 to be processed to the veneer cutting station, so that the corresponding fixture group 230 in the transfer mechanism 200 can release the positioning of the battery casing 2000 at the veneer cutting station. Then, the horizontal drive component 210 and the lifting drive component 220 cooperate to make each fixture group 230 return from the current station to the previous station, and each fixture group 230 locks the battery casing 2000 at the loading station and the veneer cutting station again. Simultaneously, the first rotary cutting component 310 completes the rotary cutting of the battery casing 2000, and the first fixing component 320 unlocks the rotary-cut battery casing 2000. The horizontal drive component 210 can then quickly transfer each fixture group 230 to the next station, allowing the rotary-cut battery casing 2000 to be transported to the unloading station, and the battery casing 2000 at the loading station to be transported to the rotary cutting station, restarting the cycle of processing. Therefore, this processing equipment has a shorter dwell time during material handling and can quickly complete unloading and reloading after the battery casing 2000 is rotary-cut, resulting in higher processing efficiency and improved overall production efficiency.

[0023] It should be noted that the jig assembly 230 is used to position the battery casing 2000. This means that the jig assembly 230 can lock and fix the battery casing 2000 during transfer and processing, and can release the limiting position on the battery casing 2000 when needed, allowing the battery casing 2000 to be unlocked so that the first fixing component 320 can transfer the battery casing 2000. The positioning method of the jig assembly 230 can be various, such as clamping, magnetic adsorption, vacuum adsorption, etc., as long as it can achieve the unlocking or locking of the battery casing 2000, it is acceptable; no limitation is made here. (Refer to...) Figure 3 For example, in this application, the fixture assembly 230 includes a fixture 231, which includes a first clamping drive 2311, a receiving seat 2313, and two first grippers 2312. The first clamping drive 2311 drives the two first grippers 2312 to move towards each other in a first direction to clamp the battery casing 2000. The receiving seat 2313 is disposed between the two grippers to support the battery casing 2000. Preferably, multiple fixtures 231 can be provided, and the multiple fixtures 231 are arranged at intervals along the first direction. In this way, the material transfer mechanism 200 can simultaneously transfer multiple battery casings 2000 back and forth between two workstations, and the rotary cutting mechanism 300 can simultaneously rotary cut multiple battery casings 2000, resulting in higher production efficiency. For example, in this application, two fixtures 231 are provided.

[0024] Reference Figure 2In one embodiment, the material transfer mechanism 200 further includes a lifting frame 240 and a connecting member 250; the lifting frame 240 is slidably connected to the machine base 100 in a second direction, and the lifting frame 240 is connected to the lifting drive member 220, in the second direction (e.g. Figure 1 and Figure 2 (As shown in the Z direction) perpendicular to the first direction; the connecting member 250 is mounted on the lifting frame 240, and the connecting member 250 extends in the first direction and slides in cooperation with the lifting frame 240; the fixture assembly 230 is mounted on the connecting member 250; the output end of the horizontal drive member 210 is connected to one end of the connecting member 250; wherein, when the lifting frame 240 drives the connecting member 250 to rise and fall, the horizontal drive member 210 can move along with the connecting member 250. With this configuration, the lifting frame 240 enables the lifting drive member 220 to drive each fixture assembly 230 to rise and fall smoothly along the second direction. The connecting member 250 slides in cooperation with the lifting frame 240. After the lifting and falling is in place, the horizontal drive member 210 can drive the connecting member 250 to translate along the first direction, thereby driving each fixture assembly 230 to reciprocate between adjacent workstations, ensuring that each fixture assembly 230 can move accurately in the preset path.

[0025] It is worth mentioning that, compared to the solution of directly setting a linear module to drive the jig assembly 230 for translation, this application adopts a single connector 250 extending along the first direction to simultaneously support multiple jig assemblies 230, making the layout of the entire device more compact. Furthermore, the length and cross-sectional dimensions of the connector 250 can be flexibly adjusted according to the actual workstation spacing and space requirements, facilitating spatial avoidance and coordination with other mechanisms such as the feeding mechanism 500, the rotary cutting mechanism 300, and the unloading mechanism 400, thereby improving the overall flexibility and structural compactness of the equipment layout.

[0026] Specifically, the lifting drive 220 can be a cylinder or a linear motor, and the lifting frame 240 can be mounted on the machine base 100 via a slide rail. Preferably, the machine base 100 is provided with a clearance for the lifting frame 240 to pass through, so that the lifting frame 240 can be partially located inside the machine base 100, reducing the occupation of external space. When the lifting frame 240 rises in the second direction, each fixture assembly 230 can pick up the battery case 2000 at each workstation, so that the connecting piece 250 can then move the fixture assembly 230 to the next workstation. When the lifting frame 240 descends in the second direction, the battery case 2000 of each fixture assembly 230 is transferred to the corresponding workstation, and each fixture assembly 230 is idle. Then, the horizontal drive 210 and the lifting drive 220 work together to return each fixture assembly 230 to the previous workstation. When the lifting drive 220 drives the lifting frame 240 to descend, each fixture assembly 230 places the material at the corresponding workstation. The horizontal drive 210 is used to move each fixture group 230 to the next station when the connector 250 is in the rising position, and to return each fixture group 230 to the previous station when the connector 250 is in the falling position.

[0027] Reference Figure 2 In one embodiment, the horizontal drive member 210 includes a push rod 211 and a body 212, the body 212 being used to drive the push rod 211 to extend or retract; the push rod 211 is connected to one end of the connector 250, and the body 212 is positioned in a third direction (e.g., in the horizontal direction). Figure 1 and Figure 2 (As shown in the Y direction) Rotatably mounted on the machine base 100, so that when the lifting seat drives the connecting member 250 to rise and fall, the main body 212 can swing along with the connecting member 250 (e.g., Figure 2 (As shown in the O direction), the third direction is perpendicular to the second and first directions respectively. With this configuration, only the main body 212 needs to swing to adapt to the rising and falling of the connector 250, which simplifies the structure. Moreover, since only the main body 212 swings with the connector 250, it occupies less space and is conducive to a more compact overall layout.

[0028] Specifically, one end of the push rod 211 is hinged to one end of the connector 250 or connected via a floating joint. A hinge seat is fixed on the machine base 100, and the main body 212 is rotated around an axis (such as...) Figure 2 (As shown in L3) is rotatably connected to the hinge seat. When the lifting frame 240 drives the connecting piece 250 to rise and fall, the height position of the connecting piece 250 changes, and the main body 212 will swing adaptively along the third direction with the push rod 211, so that the push rod 211 and the connecting piece 250 can be better connected.

[0029] Reference Figure 2 In one embodiment, a lifting mechanism 260 is also included, which is correspondingly arranged with the horizontal drive member 210. The lifting mechanism 260 is used to support the main body 212 when it swings. With this arrangement, the lifting mechanism 260 can provide auxiliary support to the main body 212, prevent swaying when the horizontal drive member 210 drives the connecting member 250 to translate, and improve the reliability of the material transfer mechanism 200.

[0030] Specifically, the lifting mechanism 260 can be a lifting cylinder. The lifting mechanism 260 is located below or beside the main body 212. During the process of the main body 212 swinging up and down with the connecting member 250, the lifting mechanism 260 can drive the output end to move with the main body 212 to apply a supporting force to the main body 212.

[0031] Reference Figure 4 and Figure 5In one embodiment, when the jig assembly 230 fixes the battery casing 2000, the battery casing 2000 is exposed outside the jig assembly 230 at both ends in the third-party direction; the first fixing component 320 includes a power source 321, a first fixing member 322, and a second fixing member 323. The first fixing member 322 and the second fixing member 323 are located on both sides of the jig assembly 230 in the third-party direction. The power source 321 is connected to the first fixing member 322 and the second fixing member 323, and is used to drive the first fixing member 322 and the second fixing member 323 towards each other in the third-party direction (e.g., ...). Figure 5 The first fixing member 322 and the second fixing member 323 are moved (as shown in the directions of U1 and U2) to limit and fix the two ends of the battery case 2000 respectively. With this configuration, the first fixing member 322 and the second fixing member 323 can lock and unlock the battery case 2000 by moving towards or away from each other, and both ends of the battery case 2000 are fixed, resulting in a better fixing effect.

[0032] Specifically, after the jig assembly 230 transfers the battery casing 2000 to the rotary cutting station, the power source 321 consists of two cylinders. These cylinders drive the first fixing member 322 and the second fixing member 323 to move in opposite directions along a third direction, clamping and positioning both ends of the battery casing 2000. At this time, the battery casing 2000 is securely fixed to the rotary cutting station by the first fixing component 320, allowing the jig assembly 230 at the corresponding loading and unloading stations to release the positioning of the battery casing 2000. After rotary cutting is completed, the two cylinders drive the first fixing member 322 and the second fixing member 323 to move in opposite directions, releasing the fixing of the battery casing 2000. The jig assembly 230 at the corresponding rotary cutting and unloading stations can then remove the rotary-cut battery casing 2000.

[0033] Preferably, the first fixing member 322 is provided with a limiting hole for one end of the battery to pass through, and the second fixing member 323 is provided with a receiving groove for accommodating the other end of the battery case 2000, so as to better limit and fix the battery case 2000.

[0034] In one embodiment, the first fixing component further includes a stop member disposed on the first fixing member 322 and the second fixing member 323, for limiting the maximum distance that the first fixing member 322 and the second fixing member 323 can move toward each other, so as to ensure that the first fixing member 322 and the second fixing member 323 can fix the battery casing 2000 of the corresponding length.

[0035] Reference Figure 4 and Figure 5In one embodiment, the rotary cutting mechanism 300 is connected to the power source 321. The rotary cutting mechanism 300 includes a rotary drive 311 and a cutting tool 312. The cutting tool 312 and the fixture assembly 230 are arranged adjacent to each other in a third direction. When the battery casing 2000 is fixed by the first fixing member 322 and the second fixing member 323, the cutting tool 312 extends into the battery casing 2000. The rotary cutting drive is connected to the cutting tool 312 and is used to drive the cutting tool 312 to rotate so that the cutting tool 312 can rotary cut the battery casing 2000. With this configuration, while the first fixing assembly 320 and the second fixing assembly 340 fix the battery casing 2000, the cutting tool 312 can move synchronously into the battery casing 2000 to perform rotary cutting, resulting in higher processing efficiency.

[0036] Specifically, one end of the battery casing 2000 has an opening communicating with the interior. When the first fixing member 322 and the second fixing member 323 move towards each other and clamp both ends of the battery casing 2000, the cutter 312 extends into the current interior of the battery casing 2000 in a third-direction upward direction. The rotation drive member 311 is a rotary motor, which drives the cutter 312 to rotate and perform rotary cutting on the casing wall of the battery casing 2000. Since the first fixing member 320 reliably fixes the battery casing 2000 from both ends, the battery casing 2000 will not be displaced during the rotary cutting process, ensuring the accuracy and stability of the rotary cutting.

[0037] Reference Figure 1 , Figure 4 as well as Figure 5 In one embodiment, the rotary cutting station includes initial rotary cutting stations (such as...) sequentially arranged in a first direction. Figure 1 (as shown in P2) and secondary rotary cutting position (as shown in P2) Figure 1 (As shown in P3 of the diagram). The rotary cutting mechanism 300 also includes a second rotary cutting component 330 and a second fixing component 340. The first rotary cutting component 310 and the first fixing component 320 are disposed at the secondary rotary cutting position, and the second rotary component and the second fixing component 340 are disposed at the initial rotary cutting position. The second fixing component 340 alternately cooperates with the fixture group 230 on the rotary cutting position to remove the battery casing 2000 to be processed from the fixture group 230 and to put the rotary-cut battery casing 2000 back into the fixture group 230. The second rotary cutting component 330 cooperates with the second fixing component 340 to pre-cut the battery casing 2000 on the second fixing component 340. With this configuration, the battery casing 2000 is gradually cut off by performing pre-cutting at the initial rotary cutting position and final rotary cutting at the secondary rotary cutting position, which helps to reduce the deformation of the battery casing 2000 and improve the reliability of rotary cutting.

[0038] Specifically, the battery casing 2000 to be processed is first transferred to the initial rotary cutting position. After the second fixing component 340 fixes the battery casing 2000, the second rotary cutting component 330 performs a first rotary cut on the battery casing 2000, removing most of the casing wall that needs to be cut off. After the first rotary cut is completed, the fixture assembly 230 transfers the battery casing 2000 to the second rotary cutting position. After the first fixing component 320 fixes the battery casing 2000, the first rotary cutting component 310 performs a second rotary cut on the battery casing 2000, completing the cutting of the remaining part. This step-by-step rotary cutting method results in a smaller cutting amount for each rotary cut, less stress on the battery casing 2000, less likelihood of deformation, and higher cut quality.

[0039] The second rotary cutting component 330 and the second fixing component 340 are configured in the same way as the first rotary cutting component 310 and the first fixing component 320, respectively, and will not be described again here.

[0040] Reference Figure 6 In one embodiment, a feeding mechanism 500 is also included. The feeding mechanism 500 is mounted on the machine base 100 and corresponds to the feeding station. The feeding mechanism 500 includes a storage component 510 and a conveying component 520. The storage component 510 is used to store battery casings 2000 and supply them to the transfer mechanism 200. The conveying component 520 is used to convey the battery casings 2000 from the storage component 510 to the fixture group 230 at the feeding station. With this configuration, the storage component 510 and the conveying component 520 work together to achieve automatic feeding and loading of battery casings 2000, reducing manual intervention, reducing downtime, and improving overall production efficiency.

[0041] Specifically, the storage assembly 510 can be a vibratory feeder or a conveyor belt, used to store the battery casings 2000 to be processed and to supply them to the handling assembly 520. The handling assembly 520 includes a picking seat and a robot arm. The robot arm is connected to the picking seat and is used to drive the picking seat to transfer between the storage assembly 510 and the loading station. The picking seat can pick up and put down the battery casings 2000 by adsorption or clamping, and transport the battery casings 2000 one by one to the fixture group 230 at the loading station for positioning.

[0042] Reference Figure 7 and Figure 8 In one embodiment, a feeding mechanism 400 is also included. The feeding mechanism 400 is mounted on the machine base 100 and corresponds to the feeding station. The feeding mechanism 400 includes a conveying assembly 410 for conveying the spun-cut battery casing 2000. The conveying assembly 410 has a clearance area 411 on the side adjacent to the spun-cutting mechanism 300 (e.g., Figure 7 and Figure 8As shown in G), the corresponding fixture group 230 can move to the clearance area 411, which can transfer the already cut battery casing 2000 in the fixture 231 to the conveying component 410; in this way, by setting the clearance area 411, the conveying component 410 allows the battery casing 2000 on the fixture group 230 to be directly placed on the conveying component 410, realizing automatic unloading.

[0043] Specifically, the conveying component 410 can be a conveyor belt line, which conveys the battery case 2000 out of the unloading area; the conveying component 410 can also be an inclined guide chute, in which the battery case 2000 rolls down the guide chute by its own weight to achieve unloading.

[0044] The clearance area 411 of the conveying assembly 410 provides lifting and clearance space for the fixture assembly 230 corresponding to the rotary cutting station and the unloading station. During unloading, the connecting piece 250 drives the fixture assembly 230 located at the unloading station to descend, and both ends of the battery shell 2000 are exposed outside the fixture assembly 230. When the fixture assembly 230 descends to the clearance area 411, both ends of the battery shell 2000 overlap with the conveying assembly 410, and the conveying assembly 410 directly receives the battery shell 2000. Subsequently, the fixture assembly 230 releases its positioning of the battery shell 2000, and the connecting piece 250, while maintaining its descending position, moves back to its original position, driving the fixture assembly 230 back to the rotary cutting station. The battery shell 2000 is then left on the conveying assembly 410, completing the unloading and transfer.

[0045] Reference Figure 9 and Figure 10 In one embodiment, the battery casing processing equipment 1000 is further provided with a dust blowing station (e.g., Figure 1 As shown on page 5, the dust blowing station is located in the first direction between the rotary cutting station and the unloading station; it also includes a dust blowing mechanism 600, which is mounted on the machine base 100 and corresponds to the dust blowing station. The dust blowing mechanism 600 includes a first limiting component 610 and a dust blowing component 620. The first limiting component 610 and the fixture group 230 are arranged adjacent to each other in the third direction for picking up and placing the rotary-cut battery casing 2000 on the corresponding fixture group 230. The dust blowing component 620 cooperates with the first limiting mechanism to clean the dust from the rotary-cut battery casing 2000. With this configuration, the dust blowing mechanism 600 can clean the dust from the rotary-cut battery casing 2000, which is beneficial for the battery casing 2000 to perform other processes in the future.

[0046] Specifically, the first limiting component 610 includes a transfer drive 611, a second clamping drive 612, and two second grippers 613. After the rotary-cut battery casing 2000 is transferred to the dust blowing station by the fixture assembly 230, the transfer drive 611 drives the two second grippers 613 to align with one end of the battery casing 2000, and the second clamping drive 612 drives the two second grippers 613 to move and clamp the battery casing 2000. The dust blowing assembly 620 includes a suction seat 621, which is connected to a vacuum assembly to vacuum the battery casing 2000. After the dust cleaning is completed, the first limiting component 610 releases the battery casing 2000 from the lock, and the corresponding fixture assembly 230 retrieves the battery casing 2000.

[0047] Reference Figure 9 and Figure 10 In one embodiment, the battery casing processing equipment 1000 is further provided with a grinding station (e.g., Figure 1 As shown on page 4, the grinding station is located in the first direction between the rotary cutting station and the unloading station; it also includes a grinding mechanism 700, which is mounted on the machine base 100 and corresponds to the grinding station. The grinding mechanism 700 includes a second limiting component 710 and a grinding component 720. The second limiting component 710 and the fixture group 230 are arranged adjacent to each other in the third direction for picking up and placing the rotary-cut battery casing 2000 on the corresponding fixture group 230. The grinding component 720 cooperates with the second limiting mechanism to grind the surface of the rotary-cut battery casing 2000. With this configuration, the grinding mechanism 700 can grind the cut surface of the rotary-cut battery casing 2000, remove burrs from the battery casing 2000, and facilitate subsequent processing of the battery casing 2000.

[0048] Specifically, the second limiting component 710 is configured in the same way as the first limiting component 610, and will not be repeated here. After the rotary-cut battery casing 2000 is transferred to the grinding station by the fixture assembly 230, the fixture assembly 230 is unlocked, and the second limiting component 710 limits and fixes the battery casing 2000. The grinding assembly 720 includes a rotational power component 721, a grinding wheel component 722, and a translational drive component 723. The rotational power component 721 is connected to the grinding wheel component 722 and is used to drive the grinding wheel component 722 to rotate to grind the cut surface of the battery casing 2000. More specifically, the grinding assembly 720 also includes a translation drive 723, which is connected to the grinding wheel 722 and is used to drive the grinding wheel 722 to move in a first direction. Thus, when the fixture assembly 230 is provided with multiple fixtures 231, the translation drive 723 can drive the grinding wheel 722 to grind each battery casing 2000.

[0049] Reference Figure 7 and Figure 8In one embodiment, the battery casing processing equipment 1000 is further provided with a punching station (e.g., ...). Figure 1 As shown on page 7, the punching station is located in the first direction between the rotary cutting station and the unloading station; it also includes a punching mechanism 800, which is mounted on the machine base 100 and corresponds to the punching station. The punching mechanism 800 alternately cooperates with the fixture group 230 on the punching station to adjust the position of the rotary-cut battery casing 2000 when the corresponding fixture group 230 is released from positioning. With this configuration, since the length of the battery casing 2000 changes after rotary cutting, its relative position on the fixture group 230 will change accordingly. The punching mechanism 800 can adjust the position of the shortened battery casing 2000, facilitating its unloading at the unloading station.

[0050] Specifically, the punching mechanism 800 includes a first punching component 810, a second punching component 820, and a punching drive component 830. The first punching component 810 and the second punching component 820 are respectively disposed on both sides of the fixture assembly 230 in the third direction. The punching drive component 830 can be two cylinders. The punching drive component 830 is connected to the first punching component 810 and the second punching component 820 and is used to drive the first punching component 810 to be inserted into the battery case 2000 and to drive the second punching component 820 to abut against the bottom of the battery case 2000. The first punching component 810 and the second punching component 820 cooperate to apply force to the bottom of the battery case 2000 and finally punch a battery hole at the bottom of the battery case 2000.

[0051] To better understand how this application works, the following detailed workflow is provided as supplementary explanation; This battery casing processing equipment 1000 is provided with a loading station, a primary rotary cutting station, a secondary rotary cutting station, a dust blowing station, a grinding station, a punching station, and a unloading station arranged sequentially along a first direction. Corresponding to each station, the material transfer mechanism 200 is equipped with six fixture sets 230, each fixture set 230 being responsible for transferring the battery casing 2000 between two adjacent stations. Taking a complete operation cycle as an example, its workflow includes the following steps: Step 1: In the initial state of the cycle, each fixture group 230 is loaded with battery casings 2000. The horizontal drive unit 210 drives the connecting unit 250 to translate along the first direction, causing each fixture group 230 to move synchronously. For example, the first fixture group 230 at the loading station moves the battery casings 2000 to be processed to the initial rotary cutting position; the second fixture group 230 at the initial rotary cutting position moves the battery casings 2000 to be processed to the secondary rotary cutting position; the third fixture group 230 at the secondary rotary cutting position moves the rotary-cut battery casings 2000 to the dust blowing position; the fourth fixture group 230 at the dust blowing position moves the battery casings 2000 to the grinding position; the fifth fixture group 230 at the grinding position moves the battery casings 2000 to the punching position; and the sixth fixture group 230 at the punching position moves the battery casings 2000 to the unloading position.

[0052] Step Two: After the battery casings are transferred to their positions, the fixing components, the first limiting component 610, and the second limiting component 710 at each workstation fix the battery casings 2000 on their respective fixture groups 230. For example, the second fixing component 340 at the initial rotary cutting position fixes the battery casing 2000 transferred from the first fixture group 230; the first fixing component 320 at the secondary rotary cutting position fixes the battery casing 2000 transferred from the second fixture group 230; and the first limiting component 610 at the dust blowing station and the second limiting component 710 at the grinding station fix their respective battery casings 2000. After fixing, each fixture group 230 releases its positioning of the battery casing 2000 it carries. Simultaneously, the punching mechanism 800 at the punching station punches holes in the corresponding battery casing 2000 and fixes it.

[0053] Step 3: After each fixture group 230 is released from its positioning, the lifting drive 220 drives the lifting frame 240 to descend along the second direction, causing the connecting piece 250 and each fixture group 230 to descend together, so that each fixture group 230 detaches from the corresponding battery casing 2000. Simultaneously, the fixture group 230 at the unloading station transfers the battery casing 2000 onto the conveying component 410 of the unloading mechanism 400. Subsequently, the horizontal drive 210 drives the connecting piece 250 to reverse and reset along the first direction while the connecting piece 250 is in the descending position, so that each fixture group 230 returns to the previous station: the first fixture group 230 returns to the loading station, the second fixture group 230 returns to the initial rotary cutting position, the third fixture group 230 returns to the secondary rotary cutting position, and so on for the remaining fixture groups 230.

[0054] Step 4: After resetting, the lifting drive 220 drives the lifting frame 240 to rise again in the second direction, raising each fixture group 230 to the receiving height. At this time, the first fixture group 230 returns to the loading station and is idle. The conveying device in the loading mechanism 500 transports the battery casings 2000 to be processed in the storage component 510 to the loading station and loads them onto the first fixture group 230 for positioning. The second fixture group 230 returns to the initial rotary cutting position and receives the pre-cut battery casings 2000 from the second fixing component 340. The third fixture group 230 returns to the secondary rotary cutting position and receives the final rotary cut battery casings 2000 from the first fixing component 320. The remaining fixture groups 230 similarly receive the processed battery casings 2000 at their respective stations. The sixth fixture group 230 returns to the punching station. After being left empty at the unloading station, it receives the calibrated battery casing 2000 at the punching station.

[0055] Step 5: While Step 3 and Step 4 are being executed, the mechanisms at each workstation perform processing operations on the battery casing 2000 fixed to the corresponding fixing component or limiting component: the second rotary cutting component 330 at the initial rotary cutting position performs pre-rotary cutting on the battery casing 2000 on the second fixing component 340; the first rotary cutting component 310 at the secondary rotary cutting position performs final rotary cutting on the battery casing 2000 on the first fixing component 320; the dust blowing component 620 at the dust blowing station cleans the battery casing 2000 on the first limiting component 610; the grinding component 720 at the grinding station grinds the cut edges of the battery casing 2000 on the second limiting component 710; the punching mechanism 800 at the punching station adjusts the position of the battery casing 2000; and the unloading mechanism 400 at the unloading station sends out the processed battery casing 2000 transferred from the sixth fixture group 230. In this cycle, each fixture group 230 and the fixed components at each workstation work together alternately, and the transfer and processing of the battery casing 2000 are carried out simultaneously, realizing the efficient flow and gradual processing of the battery casing 2000 between each workstation. The equipment operates in a compact cycle and has high processing efficiency.
