Description

Technical Field

[0001] The present invention relates to a battery technology, and more particularly to a cutting machine for batteries. Background Art

[0002] The application of batteries has become increasingly popular, gradually expanding from small household appliances and electronic devices to large electric locomotives. In particular, in recent years, the rise of new energy vehicles has driven the development of battery technology. Among them, lithium batteries in batteries have been widely used due to many advantages such as stable power supply, good endurance, and long service life.

[0003] However, after a long period of use, batteries may need to be replaced or scrapped due to reasons such as reduced power storage efficiency or material aging. The resulting waste batteries, if not recycled, will have a great impact on the environment. At present, the recycling treatment methods for waste batteries with different material systems are also different. For example, ternary system waste lithium batteries are crushed and sorted to obtain positive and negative mixed powders for extracting precious metals from the materials, thereby achieving recycling; however, iron lithium batteries contain less precious metals, and the method of using positive and negative mixed powders has low recycling efficiency, increasing the extraction cost of the wet method and having very low economic value. It is necessary to finely disassemble the positive and negative electrodes to separate them, so that all materials can be effectively recycled.

[0004] Therefore, when recycling waste aluminum shell batteries of the iron lithium type, it is first necessary to cut them to separate the internal wound cores. Existing cutting machines have low efficiency, poor product compatibility, generate a large amount of dust during the cutting process, and the electrolyte in the aluminum shell battery will not only affect the normal operation of the cutting machine but also pollute the environment. Summary of the Invention

[0005] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide a device for automatically, intelligently, and flexibly cutting square power aluminum shell lithium batteries, which not only improves efficiency but also can be compatible with batteries of various shapes, and prevents the impact of dust and the like during the cutting process on the environment and operators.

[0006] The present invention provides a fully automatic cutting machine for aluminum shell batteries, including: a feeding and conveying component, and a double-station displacement manipulator located at the end of the feeding and conveying component; the double-station displacement manipulator, a double-knife shaft servo lifting cutting mechanism, a side cutting lifting and translation cutting mechanism, and a shell-core separation and offline mechanism are placed in a square shape, and a double-station rotary servo manipulator is located at the center of the square shape; among them, the double-station displacement manipulator and the shell-core separation and offline mechanism are symmetrically placed with respect to the double-station rotary servo manipulator, and the double-knife shaft servo lifting cutting mechanism and the side cutting lifting and translation cutting mechanism are symmetrically placed with respect to the double-station rotary servo manipulator.

[0007] The present invention optimizes the structure of the fully automatic cutting machine for aluminum shell batteries, making the structure more compact.

[0008] Furthermore, the feeding and conveying component includes a conveyor belt, a blocking mechanism, and a positioning cylinder located on one side of the blocking mechanism.

[0009] Furthermore, the feeding and conveying component further includes a lifting mechanism installed in the middle of the conveyor belt.

[0010] The positioning cylinder pushes the aluminum shell battery to the blocking mechanism to achieve the positioning of the aluminum shell battery, facilitating the accurate grasping by the double-station transfer manipulator.

[0011] Furthermore, the double-station rotary servo manipulator further includes a servo gripper and a rotary cylinder. Driven by the rotary cylinder, after the servo gripper grasps the aluminum shell battery, it switches positions between the cutting station and the side-cutting station, thereby improving efficiency. The servo motor of the servo gripper uses torque mode control and can automatically adapt to aluminum shell batteries of various widths.

[0012] Furthermore, the double-knife-axis servo-lifting cutting mechanism further includes a blade and a protective cover. The protective cover enables the cutting operation to be carried out in a semi-closed environment, preventing the spillage of cutting aluminum powder. Preferably, a flame detection device is installed inside the protective cover to detect the fire for timely fire protection treatment.

[0013] Furthermore, the double-knife-axis servo-lifting cutting mechanism further includes a blade automatic translation device, which is connected to the blade and adjusts the cutting positions of the two blades according to the length of the aluminum shell battery.

[0014] Furthermore, the double-knife-axis servo-lifting cutting mechanism further includes a blade automatic lifting device, which is connected to the blade and adjusts the cutting depth of the blade according to the thickness of the aluminum shell battery.

[0015] Both the blade automatic translation device and the blade automatic lifting device contribute to the full cutting of the aluminum shell battery.

[0016] Furthermore, the side-cutting lifting and translation cutting mechanism includes a displacement sensor located on the side wall of the side-cutting lifting mechanism. It detects the height of the upper surface of the aluminum shell battery to be cut and automatically adjusts the cutting depth according to the height to achieve follow-up automatic cutting and prevent cutting into the internal winding core after the shell deforms.

[0017] Furthermore, the side-cutting lifting and translation cutting mechanism further includes a lifting displacement module, which is connected to the cutting tool to adjust the rising and falling of the cutting tool.

[0018] Furthermore, the side-cutting lifting and translation cutting mechanism further includes a cutting tool lateral displacement module, which is connected to the cutting tool to drive the cutting tool to move laterally.

[0019] Furthermore, the shell-core separation and offline mechanism includes a push rod, which is a double push rod mechanism. The position of one push rod is fixed, and the other push rod is movable.

[0020] Furthermore, the shell-core separation and offline mechanism further includes a battery clamping device and a pneumatic blocking mechanism located at the front end of the battery clamping device.

[0021] The present invention also proposes a fully automatic cutting method for aluminum shell batteries, which is applied to the above-mentioned fully automatic cutting machine for aluminum shell batteries. The cutting method includes the following steps:

[0022] Step S1: The aluminum shell batteries are arranged in sequence and placed on the conveyor belt to drive the aluminum shell batteries to approach the front end of the blocking position of the blocking mechanism.

[0023] Step S2: The aluminum shell batteries enter the feeding conveyor component in sequence, and fix the aluminum shell batteries to be cut at the position of the blocking mechanism.

[0024] Step S3: The first jaw of the double-station displacement and transfer manipulator grabs the positioned aluminum shell battery and transports it to the rotating table; Step S4: The servo jaw of the double-station rotating servo manipulator grabs the aluminum shell battery, and through the action of the rotating cylinder, sends the waste battery into the cutting station.

[0025] Step S5: At the cutting station, the double-knife-axis servo lifting and cutting mechanism cuts both ends of the aluminum shell battery.

[0026] Step S6: Driven by the rotating cylinder, the servo jaw grabs the aluminum shell battery whose two ends have been cut and transports it to the side cutting station.

[0027] Step S7: At the side cutting station, the side cutting lifting and translation cutting mechanism cuts the side wall of the aluminum shell battery.

[0028] Step S8: Another jaw of the double-station manipulator takes out the aluminum shell battery whose two ends and side wall have been cut from the side cutting station and places it on the shell-core separation and offline mechanism; Step S9: The shell-core separation and offline mechanism separates the core and the shell of the aluminum shell battery. During the cutting process, information such as the height of the aluminum shell battery is detected in real time, so as to adjust the position of the blade or scraper, making the cutting accurate and sufficient, and improving the accuracy. In the fully automatic cutting machine for aluminum shell batteries, each component works independently, adapting to the assembly line work, and also improving the work efficiency.

[0069] Figure 2 The structural schematic diagram of the feeding conveyor component 11 is shown.

[0070] The feeding conveyor component 11 includes a blocking mechanism 113 for positioning the aluminum-shell battery; a conveyor belt 111 located on one side of the blocking mechanism 113 for conveying the aluminum-shell battery; a positioning cylinder 114 located on the other side of the blocking mechanism 113 for pushing the aluminum-shell battery, which acts together with the blocking mechanism 113 to position the aluminum-shell battery; and a lifting mechanism 112 located in the middle of the conveyor belt 111 for lifting the aluminum-shell battery.

[0071] The aluminum-shell battery WB is transported by the conveyor belt 111 and stops at position A due to the blocking mechanism 113; after the photoelectric sensor installed at the front end of the blocking mechanism 113 detects the aluminum-shell battery, the lifting mechanism 112 starts to work, pushing out the aluminum-shell batteries except those near the blocking position, making them higher than the conveyor belt, the blocking mechanism 112 rises, the motor of the feeding conveyor component 11 starts, sending the aluminum-shell battery near the blocking position to the tail of the conveyor belt 111, and the blocking mechanism 112 descends.

[0079] The double-station rotary servo manipulator 13 includes servo jaws 132 located on both sides of the swing arm for grasping and transporting the aluminum shell battery; a rotary cylinder 131 located under the platen of the rotating table for driving the servo jaws 132 to move, so that the aluminum shell battery WB is transported to the double-knife-axis servo lifting cutting mechanism 14.

[0080] After the servo jaws 132 clamp the aluminum shell battery WB, under the drive of the rotary cylinder 131, the servo jaws 132 feed the aluminum shell battery WB to be cut into the cutting station, and then feed the cut aluminum shell battery WB into the side cutting station after cutting, so that the aluminum shell battery WB is converted between the cutting station and the side cutting station, and then cooperates with the transfer manipulator 12 to realize the automatic loading and unloading of the aluminum shell battery and the transfer between workstations.

[0081] Preferably, the servo jaws 132 are electric jaws that clamp the aluminum shell battery according to a set torque, making the battery more stable and not falling off.

[0083] The double - cutter - shaft servo - lifting cutting mechanism 14 includes a servo motor 141, which is located above the cutting station; and a blade 142, which is located on one side of the lifting device. After the servo gripper 132 feeds the aluminum - shell battery WB to be cut into the cutting station, the servo motor 141 drives the blade 142 to move downward to cut both ends of the aluminum - shell battery WB.

[0087] The side - cutting lifting and translation cutting mechanism 15 includes a displacement sensor 151, a cutting tool 152, and a lifting mechanism 153. Among them, the displacement sensor 151 and the cutting tool 152 are respectively located on the side wall of the side - cutting lifting mechanism and the upper part of the lifting and moving table. During the cutting process, the optical displacement sensor detects the height of the position to be cut on the upper surface of the aluminum - shell battery, and automatically adjusts the cutting depth according to the height to achieve follow - up automatic cutting and prevent cutting into the internal winding core after the deformation of the outer shell.

[0093] The second jaw 123 takes out the aluminum shell battery with both ends and the side wall cut from the processing turntable and places it on the shell-core separation offline mechanism 16. A battery clamping device clamps the aluminum shell battery WB with a constant torque by a servo motor. Under the horizontal movement of the push rod 162, the aluminum shell battery WB is transported to the conveyor belt. After the push rod 162 resets, the blocking mechanism 161 descends, and then the shell is blown into the collection bin by compressed air, thus separating the aluminum shell battery core and the shell.

[0094] Furthermore, the push rod 162 is a double push rod mechanism. The position of one push rod is fixed, and the other push rod is movable. Its position is automatically adjusted according to the width of the aluminum shell battery by a stepping motor driving a rack and pinion mechanism.

[0095] Figure 8 Shows a cutting flow chart of waste batteries.

[0096] In the fully automatic aluminum shell battery cutting machine, the aluminum shell battery is cut according to the following method:

[0097] Step S1: The aluminum shell batteries are arranged in sequence and placed on the conveyor belt. The motor of the feeding conveyor mechanism is turned on, and the conveyor belt drives the aluminum shell batteries to approach the front end of the blocking position of the adjacent blocking mechanism.

[0098] It also includes using a vision detection system to detect data such as the length, width, thickness, and pole post height of the aluminum shell battery, and corresponding them one by one with the numbers of the aluminum shell batteries.

[0099] Step S2: The aluminum shell batteries enter the feeding conveyor components in sequence and are positioned for the double-station manipulator to grasp.

[0100] Specifically, after the photoelectric sensor installed at the front end of the blocking position detects the aluminum shell battery, the lifting mechanism starts to work, pushes out the aluminum shell batteries except those close to the blocking position, making them higher than the conveyor belt. The blocking mechanism rises, the motor of the feeding conveyor component starts, sends the aluminum shell battery close to the blocking position to the tail of the belt of the feeding conveyor mechanism, the blocking mechanism descends, and the positioning cylinder starts to work, pushing the aluminum shell battery onto the rear positioning plate of the blocking mechanism.

[0101] Step S3: One jaw of the double-station manipulator grasps the currently positioned aluminum shell battery and transports it to the turntable.

[0102] Specifically, it includes: a displacement sensor detects the height of the currently positioned aluminum shell battery, a lifting mechanism adjusts the grasping height of the gripper, and when the gripper reaches the currently positioned aluminum shell battery, it clamps the aluminum shell battery and transports it to the rotating table.

[0103] Step S4: The servo gripper of the double-station rotating servo manipulator grabs the aluminum shell battery, and through the action of the rotating cylinder, sends the aluminum shell battery to be cut into the cutting station.

[0104] Specifically, after the first gripper grabs the aluminum shell battery, it transfers it to the servo gripper. The servo gripper tightly holds the aluminum shell battery according to the set torque, and under the drive of the rotating cylinder, sends the aluminum shell battery to the cutting station.

[0105] Step S5: At the cutting station, the double-knife-axis servo lifting cutting mechanism cuts both ends of the aluminum shell battery.

[0106] Specifically, the translation device adjusts the width of the blade according to the height of the aluminum shell battery, and the blade moves downward under the drive of the servo motor to cut both ends of the aluminum shell battery.

[0107] Step S6: Under the drive of the rotating cylinder, the servo gripper grabs the aluminum shell battery whose both ends have been cut and transports it to the side-cutting station.

[0108] Step S7: At the side-cutting station, the side-cutting lifting and translation cutting mechanism cuts the side wall of the aluminum shell battery.

[0109] Specifically, driven by the translation mechanism, the displacement sensor moves to detect the height of the aluminum shell battery whose both ends have been cut. According to this height, the lifting mechanism adjusts the position of the cutting tool to cut the side wall of the aluminum shell battery.

[0110] Step S8: Another gripper of the double-station manipulator takes out the aluminum shell battery whose both ends and side wall have been cut from the side-cutting station and places it on the shell-core separation and offline mechanism.

[0111] Step S9: The shell-core separation and offline mechanism separates the core and the shell of the aluminum shell battery.

[0112] Specifically, after the battery clamping device grabs the aluminum shell battery, under the horizontal movement of the push rod, it places the aluminum shell battery on the conveyor belt. After the push rod resets, the blocking mechanism descends, and then compressed air blows the shell into the collection bin, thus realizing the separation of the core and the shell.

[0113] In summary, the present invention optimizes the structure of the fully automatic cutting machine for aluminum shell batteries, making the structure more compact, simplifying the cutting process, and improving the applicability and reliability. The fully automatic cutting machine for aluminum shell batteries in the present invention cuts the head and bottom of the battery simultaneously and cooperates with the cutting of the side wall to adapt to batteries of various shapes. In addition, during the cutting process, information such as the height of the aluminum shell battery is detected in real time, so as to adjust the position of the blade or scraper, making the cutting accurate and sufficient and improving the accuracy. In the fully automatic cutting machine for aluminum shell batteries, each component works independently, adapts to the assembly line work, and also improves the work efficiency.
