Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown in the figure, an end face flattening device for a circular battery casing according to an embodiment of the present invention includes a feeding mechanism 1; the feeding mechanism 1 is used to transport the battery casing to be processed; a flattening mechanism 2 is provided at the discharge end of the feeding mechanism 1; the flattening mechanism 2 is used to flatten the end face of the battery casing; a discharge transfer mechanism 3 is provided on the side of the flattening mechanism 2 away from the feeding mechanism 1; a unloading mechanism 4 is provided on the side of the discharge transfer mechanism 3 away from the flattening mechanism 2; the flattening mechanism 2 includes a plurality of lifting and lowering cutting tools 201; a rotatable chuck 202 is provided above each cutting tool 201; Specifically, the leveling mechanism 2 includes a leveling frame, with multiple electric telescopic rods 203 fixedly connected to the bottom of the leveling frame; a tool holder 204 fixedly connected to the top of the electric telescopic rods 203; a cutting tool 201 bolted to the top of the tool holder 204; a motor fixedly connected to the top of the leveling frame, with a rotating shaft 205 fixedly connected to the output shaft of the motor; and a chuck 202 fixedly connected to the bottom of the rotating shaft 205, and the chuck 202 is a pneumatic three-jaw chuck. The battery casing to be processed is conveyed by the feeding mechanism 1 to the leveling mechanism 2. The battery casing is moved to the outside of the chuck 202, and the jaws of the chuck 202 unfold to fix the battery casing. At this time, the electric telescopic rod 203 pushes the tool holder 204 to rise, so that the cutting edge of the cutting tool 201 contacts the end face of the battery casing. Simultaneously, the motor drives the rotating shaft 205 to rotate, which in turn drives the chuck 202 to rotate, causing the battery casing to rotate. Together with the cutting tool 201, the end face of the battery casing is leveled, so that the flatness of the end face of the battery casing is less than 0.05mm. After the end face of the battery casing is machined flat, the electric telescopic rod 203 drives the tool holder 204 to descend, causing the cutting tool 201 to separate from the end face of the battery casing. At the same time, the motor stops, causing the rotating shaft 205 and chuck 202 to stop rotating, thus stopping the rotation of the battery casing. The chuck 202 releases the battery casing, and at the same time, the material transfer mechanism 3 clamps the battery casing and transfers it to the unloading mechanism 4, realizing the unloading of the battery casing. This completes the automated machining of the battery casing, improving the quality of the battery casing and thus improving the quality of the battery.

[0023] like Figures 1 to 2 As shown, the leveling mechanism 2 also includes an inclined slide plate 206 disposed below the cutting tool 201; a scrap bin 207 is disposed at the bottom of the inclined slide plate 206; Specifically, the inclined slide plate 206 is fixed to the flatbed frame by bolts, and the inclined slide plate 206 and the electric telescopic rod 203 are respectively provided with openings, and the electric telescopic rod 203 slides through the openings of the inclined slide plate 206; the top surface of the waste bin 207 is open, and the bottom surface of the waste bin 207 is fixed with casters at the four corners. When the lathe tool 201 is turning the end face of the battery casing, the resulting debris falls onto the inclined slide plate 206 and slides down the inclined slide plate 206 into the waste bin 207 for collection. When a certain amount of debris accumulates inside the waste bin 207, the waste bin 207 is pulled out for cleaning and recycling. This effectively recycles and cleans the debris, improving the cleanliness of the equipment.

[0024] like Figures 1 to 3 , Figures 6 to 8As shown, the feeding mechanism 1 includes multiple feeding conveyor belts 101; the feeding conveyor belts 101 correspond to the cutting tool 201; a feeding robot 102 is arranged above the feeding conveyor belts 101; the execution end of the feeding robot 102 is provided with a feeding mechanical claw 103; Specifically, the feeding mechanism 1 includes a feeding frame, and multiple feeding conveyor belts 101 are arranged in parallel in the middle of the feeding frame; a laser positioning probe is provided on the side of the feeding mechanism 1 near the leveling mechanism 2 for positioning the conveyed battery casing. The loading robot 102 is positioned above the loading frame; the loading robot 102 includes a motor fixed to the top of the loading frame, a ball screw fixed to the output end of the motor, and a horizontal plate fixed to the outer ring of the slider of the ball screw; guide rods are fixed to both ends of the horizontal plate, and linear slide rails are fixed to the bottom ends of the guide rods on both sides; the top of the guide rods is slidably connected to the loading frame through a sliding tube; the loading mechanical claw 103 is fixed to the bottom of the electric slider of the linear slide rail; The motor on the loading robot 102 drives the linear slide rail to lift and lower through the transmission of the ball screw and the guidance of the guide rod. The electric slider of the linear slide rail drives the loading mechanical claw 103 to move horizontally, so that the electric mechanical claw can perform vertical lifting and horizontal movement. After the battery casing is placed on the top surface of the feeding conveyor belt 101, the feeding conveyor belt 101 transports the battery casing to the leveling mechanism 2. When the battery casing moves to one end of the feeding conveyor belt 101 near the leveling mechanism 2, the laser positioning probe positions the battery casing. At this time, the feeding robot 102 drives the feeding mechanical claw 103 to move, the feeding mechanical claw 103 grabs the battery casing and transports it to the chuck 202 of the leveling mechanism 2, where it docks with the chuck 202. This realizes the automatic feeding of the battery casing, improves the automation level of motor casing processing, and increases the processing efficiency of the battery casing.

[0025] like Figures 6 to 8 As shown, a plurality of feeding cylinders 104 are uniformly fixed to the outer wall of the feeding conveyor belt 101; the bottom of the feeding cylinder 104 is connected to a vacuum pump through an air pipe. Specifically, the feeding cylinder 104 has a cylindrical structure and a sealed bottom; the inner ring of the feeding cylinder 104 matches the outer ring of the battery casing, and a rubber ring is fixed to the inner wall of the feeding cylinder 104; a connector is fixed to the bottom side of the feeding cylinder 104, and the connector communicates with the inner cavity of the feeding cylinder 104; the connector at the bottom of the feeding cylinder 104 is connected to a vacuum pump through an air pipe. When loading the battery casing, the battery casing is placed inside the loading cylinder 104. At the same time, a vacuum pump creates a negative pressure inside the loading cylinder 104, which attracts the battery casing to the inside of the loading cylinder 104. This avoids the problem of displacement and tipping of the battery casing during the transportation process and improves the accuracy of battery casing transportation.

[0026] like Figures 1 to 3 , Figures 9 to 11 As shown, the material transfer mechanism 3 includes multiple mounting plates 301; a rotating rod 302 is rotatably mounted in the middle of the mounting plate 301; one side of the mounting plate 301 is provided with a rotating arm 303 fixedly connected to the rotating rod 302; a pneumatic motor 304 is provided at one end of the rotating arm 303 away from the rotating rod 302; a rotating plate 305 is fixedly connected to the output shaft of the pneumatic motor 304; a transfer mechanical claw 306 is fixedly connected to one end of the rotating plate 305 away from the pneumatic motor 304; a driving unit is provided between two mounting plates 301, and the driving unit drives the rotating rod 302 to rotate; multiple transfer conveyor belts 307 are provided on the side of the mounting plate 301 away from the leveling mechanism 2.

[0027] Specifically, the material transfer mechanism 3 includes a transfer frame, with multiple mounting plates 301 vertically and parallelly fixed inside the transfer frame; a circular hole is opened in the middle of the mounting plate 301, and a rotating rod 302 is rotatably installed inside the circular hole; a pneumatic motor 304 is connected to an air pump through an air pipe, and the high-pressure airflow of the air pump controls the pneumatic motor 304 to drive the rotating plate 305 to reciprocate forward and reverse rotation; a transfer mechanical claw 306 can realize clamping and releasing; a transfer conveyor belt 307 is fixedly connected to the transfer frame, and the transfer conveyor belt 307 corresponds to the transfer mechanical claw 306; multiple transfer cylinders 318 are evenly fixed to the outer ring of the transfer conveyor belt 307, and the inner ring of the transfer cylinder 318 matches the outer ring of the battery casing; After the end face of the battery casing is machined flat, the electric telescopic rod 203 drives the tool holder 204 to descend, causing the cutting tool 201 to separate from the end face of the battery casing. At this time, the drive unit drives the rotating rod 302 to rotate, causing the rotating arm 303 to rotate toward the chuck 202 of the machining mechanism 2. At the same time, the pneumatic motor 304 drives the rotating plate 305 to rotate, so that the transfer mechanical claw 306 approaches the battery casing at the bottom of the chuck 202. The transfer mechanical claw 306 clamps and fixes the battery casing, while the chuck 202 releases the battery casing. At this time, the drive unit drives the rotating rod 302 to reverse, causing the rotating arm 303 to rotate toward the transfer conveyor belt 307. At the same time, the pneumatic motor 304 drives the rotating plate 305 to rotate, so that the transfer mechanical claw 306 approaches the transfer cylinder 318 on the transfer conveyor belt 307. The transfer mechanical claw 306 places the battery casing into the transfer cylinder 318. Meanwhile, the transfer conveyor belt 307 transports the battery casing to the unloading mechanism 4 for automatic unloading; thereby improving the automation level of battery casing processing.

[0028] like Figures 9 to 10 As shown, a horizontal guide rail 308 is fixedly connected to the top of the mounting plate 301 near the rotating arm 303; a horizontal slide block 309 is slidably mounted on the horizontal guide rail 308; a vertical guide rail 310 is slidably mounted on the side of the horizontal slide block 309 away from the mounting plate 301; a vertical slide block 311 is slidably mounted on the vertical guide rail 310; a straight groove 312 is formed in the middle of the rotating arm 303; a U-shaped guide groove 313 is formed on the mounting plate 301; the vertical slide block 311 is slidably connected to the straight groove 312 and the U-shaped guide groove 313; the bottom end of the vertical guide rail 310 is fixedly connected to the pneumatic motor 304. Specifically, the horizontal guide rail 308 is fixed to the top of the mounting plate 301 near the rotating arm 303 by multiple screws, and the horizontal guide rail 308 is set horizontally, allowing the horizontal slide block 309 to slide horizontally along the horizontal guide rail 308; the vertical guide rail 310 is set vertically and is slidably connected to the horizontal slide block 309, allowing the vertical guide rail 310 to slide vertically along the horizontal slide block 309; a columnar connecting post is bolted to the side of the vertical slide block 311 near the mounting plate 301, and the connecting post passes through the straight groove 312 on the rotating arm 303 and then is slidably connected to the U-shaped guide groove 313 on the mounting plate 301; so that the vertical slide block 311 can slide simultaneously along the straight groove 312 and the U-shaped guide groove 313; When the drive unit drives the rotating rod 302 to rotate, and the rotating arm 303 to rotate, the vertical slide 311 slides along both the straight groove 312 and the U-shaped guide groove 313. This causes the rotating arm 303 to drive the vertical slide 311 to slide along the U-shaped guide groove 313, which in turn causes the vertical slide 311 to slide along the vertical guide rail 310. Simultaneously, the vertical slide 311 moves horizontally, causing the vertical slide 311 to drive the vertical guide rail 310 to move horizontally. This causes the vertical guide rail 310 to drive the horizontal slide 309 to slide horizontally along the horizontal guide rail 308. This ensures that the pneumatic motor 304 maintains the same stable state during operation, meaning that the angle of the pneumatic motor 304 does not change. This effectively improves the accuracy and stability of the transfer mechanical gripper 306, enabling it to accurately clamp and transfer the battery casing.

[0029] like Figures 9 to 11As shown, the drive unit includes a drive housing 314; the drive housing 314 is disposed between the two mounting plates 301; one end of the drive housing 314 is fixedly connected to a first cylinder 315; the piston rod of the first cylinder 315 slides through the interior of the drive housing 314; a rack 316 is slidably mounted inside the drive housing 314; the piston rod of the first cylinder 315 is fixedly connected to the end of the rack 316; a rotating rod 302 rotatably passes through the middle of the drive housing 314; a gear 317 is fixedly connected to the outer ring of the rotating rod 302; the gear 317 meshes with the rack 316. Specifically, the drive housing 314 is fixedly mounted to the transfer frame by bolts. The first cylinder 315 pushes the rack 316 to slide inside the drive housing 314, so that the rack 316 moves back and forth along the inside of the drive housing 314. Since the rack 316 meshes with the gear 317, the gear 317 rotates back and forth, thereby driving the rotating rod 302 to rotate back and forth, providing driving force for the operation of the discharge transfer mechanism 3.

[0030] like Figures 1 to 3 , Figure 12 As shown, the unloading mechanism 4 includes an unloading robot 401; a crossbeam 402 is fixedly connected to the bottom of the execution end of the unloading robot 401; a plurality of unloading mechanical claws 403 are provided at the bottom of the crossbeam 402; and an unloading conveyor belt 404 is provided below the unloading robot 401. Specifically, the unloading mechanism 4 includes an unloading frame, and an unloading robot 401 is fixedly installed on the top of the unloading frame. The unloading robot 401 includes a horizontal track structure and a vertical lifting structure, which can realize horizontal movement along the track structure and vertical lifting movement. The unloading robot 401 drives the crossbeam 402 to perform horizontal movement and vertical lifting movement. The number of unloading mechanical claws 403 corresponds to the number of transfer conveyor belts 307. When the transfer conveyor belt 307 transports the battery casing to the unloading mechanism 4, the unloading robot 401 moves the crossbeam 402 to above the end of the transfer conveyor belt 307. Simultaneously, the unloading robot 401 lowers the crossbeam 402, bringing the unloading manipulator 403 close to the battery casing and clamping it in place. Then, the unloading robot 401 raises the crossbeam 402 and moves it above the unloading conveyor belt 404, moving the unloading manipulator 403 and the battery casing above the unloading conveyor belt 404. At this point, the unloading robot 401 lowers the crossbeam 402, bringing the battery casing into contact with the top surface of the unloading conveyor belt 404. Simultaneously, the unloading manipulator 403 releases the battery casing, causing it to fall onto the top surface of the unloading conveyor belt 404 and be unloaded. This achieves automatic unloading of the battery casing, improving the automation level of battery casing processing.

[0031] like Figure 12 As shown, a U-shaped sliding buckle 405 is fixedly connected to the top of the unloading mechanical claw 403; the U-shaped sliding buckle 405 is slidably connected to the crossbeam 402; a cross-shaped folding telescopic frame 406 is provided on one side of the plurality of U-shaped sliding buckles 405; a second cylinder 407 is fixedly connected to one end of the top surface of the crossbeam 402; the second cylinder 407 can drive the folding telescopic frame 406 to unfold and retract. Specifically, the U-shaped sliding buckle 405 is slidably installed at the bottom of the crossbeam 402, and the top of a pair of U-shaped sliding buckles 405 near the piston rod of the second cylinder 407 is fixedly connected to a folding plate facing the top of the crossbeam 402; the end of the piston rod of the second cylinder 407 is fixedly connected to the folding plate at the top of the U-shaped sliding buckle 405; the folding telescopic frame 406 is composed of multiple pairs of connecting rods, the middle of each pair of connecting rods is rotatably connected by a hinge, and the hinge is fixedly connected to the middle of the side of the U-shaped sliding buckle 405; the ends of adjacent sets of connecting rods are rotatably connected. When the unloading robot 401 moves the crossbeam 402 to above the end of the transfer conveyor belt 307, the second cylinder 407 retracts, causing the U-shaped sliding buckle 405 to slide, which in turn causes the folding telescopic frame 406 to unfold, causing multiple U-shaped sliding buckles 405 to separate, causing multiple unloading mechanical claws 403 to separate, and causing each unloading mechanical claw 403 to align with each transfer conveyor belt 307. After the feeding robot 401 moves the crossbeam 402 above the feeding conveyor belt 404, the second cylinder 407 pushes the U-shaped sliding buckle 405 to slide in the opposite direction, causing the folding telescopic frame 406 to retract. This causes multiple U-shaped sliding buckles 405 to move closer together, and multiple feeding mechanical claws 403 to move closer together and gather in the middle of the crossbeam 402. This allows multiple battery casings to be positioned at the concentrated location of the feeding conveyor belt 404, thus facilitating the collection of the processed battery casings.

[0032] like Figures 1 to 3 Multiple packaging boxes 408 are evenly placed on the conveyor belt 404. Specifically, after the feeding robot 401 moves the crossbeam 402 above the feeding conveyor belt 404, multiple feeding mechanical claws 403 approach each other and gather in the middle of the crossbeam 402. At this time, the multiple feeding mechanical claws 403 are aligned with the inside of the packaging box 408, and multiple battery casings are placed inside the packaging box 408, thereby realizing the automatic packaging of battery casings and further improving the processing efficiency of battery casings.

[0033] Working principle: When loading the battery casing, the battery casing is placed inside the loading cylinder 104. At the same time, a vacuum pump creates a negative pressure inside the loading cylinder 104, which attracts the battery casing to the inside of the loading cylinder 104. The loading conveyor belt 101 transports the battery casing to the leveling mechanism 2. When the battery casing moves to one end of the loading conveyor belt 101 close to the leveling mechanism 2, the laser positioning probe positions the battery casing. At this time, the loading robot 102 drives the loading mechanical claw 103 to move. The loading mechanical claw 103 grabs the battery casing and transports it to the chuck 202 of the leveling mechanism 2. The jaws of the chuck 202 unfold to secure the battery casing. At this time, the electric telescopic rod 203 pushes the tool holder 204 to rise, causing the cutting edge of the cutting tool 201 to contact the end face of the battery casing. Simultaneously, the motor drives the rotating shaft 205 to rotate, causing the chuck 202 to rotate and the battery casing to rotate. Together with the cutting tool 201, the end face of the battery casing is machined flat, ensuring that the flatness of the end face of the battery casing is less than 0.05mm. The generated debris falls onto the inclined slide plate 206 and slides down the inclined slide plate 206 into the waste bin 207 for collection. When a certain amount of debris accumulates inside the waste bin 207, the waste bin 207 is pulled out for cleaning and recycling. After the end face of the battery casing is machined flat, the electric telescopic rod 203 lowers the tool holder 204, causing the cutting tool 201 to separate from the end face of the battery casing. At this time, the first cylinder 315 pushes the rack 316 to slide inside the drive housing 314, causing the rack 316 to reciprocate along the inside of the drive housing 314. Since the rack 316 meshes with the gear 317, the gear 317 reciprocates, driving the rotating rod 302 to reciprocate. When the rotating rod 302 rotates, it drives the rotating arm 303 to rotate; due to the vertical... The straight slide block 311 slides simultaneously along the straight groove 312 and the U-shaped guide groove 313, causing the rotating arm 303 to drive the vertical slide block 311 to slide along the U-shaped guide groove 313, and causing the vertical slide block 311 to slide along the vertical guide rail 310. At the same time, due to the horizontal movement of the vertical slide block 311, the vertical slide block 311 drives the vertical guide rail 310 to move horizontally, causing the vertical guide rail 310 to drive the horizontal slide block 309 to slide horizontally along the horizontal guide rail 308; thus ensuring that the pneumatic motor 304 maintains the same stable state during the movement. Rotating rod 302 rotates, causing rotating arm 303 to rotate toward chuck 202 of car leveling mechanism 2. At the same time, pneumatic motor 304 drives rotating plate 305 to rotate, so that transfer mechanical claw 306 approaches the battery casing at the bottom of chuck 202. Transfer mechanical claw 306 clamps and fixes the battery casing. At this time, the drive unit drives rotating rod 302 to reverse, causing rotating arm 303 to rotate toward transfer conveyor belt 307. At the same time, pneumatic motor 304 drives rotating plate 305 to rotate, so that transfer mechanical claw 306 approaches transfer cylinder 318 on transfer conveyor belt 307. Transfer mechanical claw 306 places battery casing into transfer cylinder 318. When the transfer conveyor belt 307 transports the battery casing to the unloading mechanism 4, the unloading robot 401 moves the crossbeam 402 to above the end of the transfer conveyor belt 307. The second cylinder 407 retracts, causing the U-shaped sliding buckle 405 to slide, which unfolds the folding telescopic frame 406, causing multiple U-shaped sliding buckles 405 to separate, and multiple unloading mechanical claws 403 to separate, so that each unloading mechanical claw 403 is aligned with each transfer conveyor belt 307. At the same time, the unloading robot 401 lowers the crossbeam 402, so that the unloading mechanical claw 403 approaches the battery casing, and the unloading mechanical claw 403 clamps and fixes the battery casing. Subsequently, the unloading robot 401 raises the crossbeam 402 and moves it above the unloading conveyor belt 404, moving the unloading robotic claw 403 and the battery casings above the unloading conveyor belt 404. Simultaneously, the second cylinder 407 pushes the U-shaped sliding buckle 405 to slide in the opposite direction, causing the folding telescopic frame 406 to retract. This brings the multiple U-shaped sliding buckles 405 closer together, causing the multiple unloading robotic claws 403 to approach each other and gather in the middle of the crossbeam 402, allowing the multiple battery casings to be positioned at the concentrated location on the unloading conveyor belt 404. At this point, the unloading robot 401 lowers the crossbeam 402, causing the battery casings to contact the top surface of the unloading conveyor belt 404. At the same time, the unloading robotic claw 403 releases the battery casings, causing them to fall onto the top surface of the unloading conveyor belt 404, placing the multiple battery casings inside the packaging box 408. This achieves automatic unloading of battery casings, improving the automation level of battery casing processing.
