Description

Technical Field

[0001] This invention relates to the field of battery peeling technology, specifically to an 18650 battery peeling machine and peeling method. Background Technology

[0002] With the widespread use of 18650 batteries in electronic devices, the need for their recycling and dismantling is becoming increasingly urgent. Removing the outer insulating film from the battery is a crucial step in the recycling and dismantling process.

[0003] Currently, traditional peeling methods mainly rely on manual labor, which suffers from low efficiency, high cost, and the potential to damage battery cells, posing safety hazards. To address these issues, some automated peeling equipment has emerged on the market. However, the high-speed rotation of these blades can lead to uneven peeling depths, irregular cuts, and even damage to the battery's steel casing, posing safety risks. Summary of the Invention

[0004] The purpose of this invention is to provide an 18650 battery peeling machine and peeling method to solve the problems mentioned in the background art, such as uneven peeling depth, uneven cuts, and even damage to the battery steel shell, which pose safety risks.

[0005] To achieve the above objectives, the present invention provides an 18650 battery peeling machine, including a frame and a peeling device and a clamping device mounted on the frame. The peeling device includes a slide rod, a sliding support, a feed cylinder, a motor, a drive shaft, a transmission assembly, and a peeling blade assembly. The slide rod is fixedly mounted on the frame. The sliding support is sleeved on the slide rod and slidably connected to the slide rod. The feed cylinder is fixedly mounted on the frame, and its piston rod is connected to the sliding support. The feed cylinder drives the sliding support to reciprocate linearly along the slide rod. The motor is fixedly mounted on the sliding support. The drive shaft is supported on the sliding support by at least two rolling bearings. The transmission assembly connects the motor output end to the drive shaft and transmits power from the motor output end to the drive shaft. The peeling blade assembly is fixedly mounted at the end of the drive shaft. The motor, drive shaft, transmission assembly, and peeling blade assembly move as a whole with the sliding support.

[0006] Furthermore, the clamping device is a centering clamping structure that axially clamps the battery from both ends. The centering clamping structure includes a clamping support, a clamping nozzle, and a clamping rod. The clamping support is fixedly installed on the side of the frame away from the feed cylinder. The clamping nozzle passes through the side of the clamping support and is slidably connected to the clamping support. The clamping rod passes through the central hole of the drive shaft, and the central axes of the clamping nozzle, the clamping rod, and the drive shaft coincide. The clamping nozzle and the clamping rod are used together to clamp and fix the battery along the axial ends of the battery.

[0007] Furthermore, the clamping rod and the center hole of the drive shaft are clearance fit so that the clamping rod remains stationary when the drive shaft rotates; a sealing structure is provided between the sliding support and the clamping rod, the sealing structure including a drive shaft end cover and a sealing ring, the drive shaft end cover is fixedly installed on the side of the sliding support, and the end of the drive shaft away from the peeling knife assembly is rotatably connected to the drive shaft end, the clamping rod passes through the drive shaft end cover, and the sealing ring is set in the gap between the drive shaft end cover and the clamping rod.

[0008] Furthermore, the clamping device also includes a locking structure, a clamping cylinder, a clamping block, and a fixing block. The locking structure is sleeved on the clamping rod and is used to lock the horizontal position of the clamping rod. The clamping cylinder is set on the clamping support, and the piston rod of the clamping cylinder moves perpendicular to the central axis of the clamping nozzle. The clamping block is fixedly connected to the output end of the clamping cylinder. After the clamping cylinder is lifted, the side of the clamping block can abut against the end of the clamping nozzle away from the end in contact with the battery.

[0009] Furthermore, the peeling knife assembly includes a peeling knife and a peeling head. The peeling head is fixedly mounted on the end of the drive shaft, and the peeling knife is fixedly mounted on the peeling head by fasteners.

[0010] Furthermore, the transmission assembly includes a first synchronous pulley, a second synchronous pulley, and a synchronous belt. The first synchronous pulley is fixedly mounted on the output end of the motor by a flat key, and the second synchronous pulley is fixedly mounted on the transmission shaft by a flat key. The first synchronous pulley is connected to the second synchronous pulley by a synchronous belt, and the synchronous belt is tensioned on the first and second synchronous pulleys.

[0011] Furthermore, the sliding support is a linear bearing housing, with a linear bearing installed inside the sliding support. The sliding rod passes through the linear bearing, and the transmission shaft is supported on the linear bearing housing through a first rolling bearing and a second rolling bearing.

[0012] Furthermore, the drive shaft is provided with an axial fixing structure, which restricts the axial displacement of the drive shaft. The axial fixing structure is a double round nut, and a thread is provided on the outer circumference of the rotating shaft. The double round nut is threadedly connected to the rotating shaft, and the double round nut abuts against the side wall of the linear bearing seat.

[0013] Furthermore, the battery peeling machine also includes a control system box and an outer casing recovery device. The control system box is located below the sliding support and contains a control module that controls the operation of the peeling machine. The outer casing recovery device is located below the battery peeling working area and is used to collect the peeled battery casing.

[0014] To achieve the above objectives, the present invention also provides a method for peeling the casing of an 18650 battery, comprising the following steps:

[0015] S1: The clamping cylinder in the clamping device drives the clamping block to rise, so that the clamping mouth abuts against the clamping block. The horizontal position of the clamping rod is adjusted so that the battery is axially clamped and fixed from both ends of the battery. The position of the clamping rod is locked by the locking structure.

[0016] S2: After the battery is secured, start the motor to drive the peeling blade to rotate, and start the feed cylinder to push the peeling blade to feed linearly towards the battery;

[0017] S3: The outer casing of the battery is peeled off by the linear feed motion of the rotating peeling blade;

[0018] S4: After peeling is completed, the feed cylinder drives the peeling blade to retract, the motor stops, and the clamping cylinder drives the clamping block to fall back, which can loosen the clamping mouth to replace other batteries to be peeled.

[0019] The present invention has the following advantages over the prior art:

[0020] 1. This invention fixes the motor, transmission components, transmission shaft, and peeling blade assembly onto a sliding support, forming an integrated mobile cutting unit. Driven by a feed cylinder, it performs linear feed along a precision slide bar. This results in an extremely short power transmission path, significantly enhanced system rigidity, and effective suppression of vibration and deviation during cutting. This ensures extreme stability of the peeling blade during high-speed rotation and feed, laying a solid mechanical foundation for achieving high-quality, consistent peeling results.

[0021] 2. This invention utilizes an axially centered clamping structure to center and clamp the battery from both ends, ensuring strict coaxiality between the battery and the high-speed rotating peeling blade assembly. This eliminates problems such as uneven peeling depth and irregular cuts caused by clamping eccentricity, allowing the insulating film to be peeled off evenly and completely. Simultaneously, it significantly reduces the risk of scratching or puncturing the battery's steel casing during peeling, thus effectively protecting the cell's integrity and ensuring operational safety.

[0022] 3. This invention achieves an automated cyclic process by setting adjustable mechanical limit blocks and proximity sensors, and interlocking them with cylinders and motors. This not only frees manual labor from tedious and potentially unsafe operations, significantly improving peeling efficiency, but also allows for adjustable clamping distance and feed stroke, enabling the equipment to quickly adapt to different batches or slightly different specifications of 18650 batteries, thus enhancing operational automation and production adaptability.

[0042] In this embodiment, the clamping device 2 is a centering clamping structure that axially clamps the battery 6 from both ends. The centering clamping structure includes a clamping support 201, a clamping nozzle 202, and a clamping rod 203. The clamping support 201 is fixedly disposed on the side of the frame 3 away from the feed cylinder 103. The clamping nozzle 202 passes through the side of the clamping support 201 and is slidably connected to the clamping support 201. The clamping rod 203 passes through the center hole of the drive shaft 105, and the central axes of the clamping nozzle 202, the clamping rod 203, and the drive shaft 105 are coincident. The clamping nozzle 202 and the clamping rod 203 are used to jointly clamp and fix the battery 6 along both ends of the axial direction. The clamping rod 203 and the center hole of the drive shaft 105 are clearance fit so that the clamping rod 203 remains stationary when the drive shaft 105 rotates. A sealing structure is provided between the sliding support 102 and the clamping rod 203. The sealing structure includes a drive shaft end cover 116 and a sealing ring. The drive shaft end cover 116 is fixedly installed on the side of the sliding support 102, and the end of the drive shaft 105 away from the peeling knife assembly 107 is rotatably connected to the end of the drive shaft 105. The clamping rod 203 passes through the drive shaft end cover 116, and the sealing ring is provided in the gap between the drive shaft end cover 116 and the clamping rod 203. The clamping device 2 also includes a locking structure 204, a clamping cylinder 205, and a clamping block 206. The locking structure 204 is sleeved on the clamping rod 203 and is used to lock the horizontal position of the clamping rod 203. The clamping cylinder 205 is set on the clamping support 201, and the piston rod of the clamping cylinder 205 moves perpendicular to the central axis of the clamping nozzle 202. The clamping block 206 is fixedly connected to the output end of the clamping cylinder. After the clamping cylinder is lifted, the side of the clamping block 206 can abut against the end of the clamping nozzle 202 away from the end that is in contact with the battery 6.

[0043] In this embodiment, the peeling knife 108 is fixed to the peeling head 109 by bolts; the peeling head 109 is connected to the drive shaft 105 by six screws; the drive shaft 105 is connected to the sliding support 102 through the first rolling shaft 114 and the second rolling shaft 115 to realize the rotational movement of the peeling head 109 and the drive shaft 105; the sliding support 102 is used to fix the drive shaft 105 horizontally by cooperating with the double round nut; the motor 104 is installed on the upper side of the sliding support 102 and is connected to the first synchronous pulley 111 by a flat key, and the first synchronous pulley 111 drives the second synchronous pulley 112 to rotate through the synchronous belt 113; there is a sealing ring between the drive shaft end cover 115 and the clamping rod 203 to prevent lubricating oil from flowing out; the drive shaft end cover 115 is fixed to the right side of the sliding support 102 by four screws.

[0044] In this embodiment, each component, through precise structural design and assembly process, constructs an efficient and stable battery peeling system. The peeling blade 108 is tightly connected to the peeling head 109 via bolts, ensuring a stable blade position during high-speed rotational peeling operations and guaranteeing peeling accuracy. The peeling head 109 and the drive shaft 105 are connected by six-point screws, enhancing their connection strength and enabling stable transmission of rotational power. The first rolling shaft 114 and the second rolling shaft 115 act as precise rotational hubs, cooperating with the sliding support 102 to not only provide the drive shaft 105 with smooth rotational freedom but also effectively distribute radial and axial loads during operation, reducing frictional losses. The sliding support 102, in cooperation with the double round nuts, achieves precise axial positioning of the drive shaft 105, preventing displacement during operation and maintaining the stability of the device. The motor 104, as the power source, is rigidly connected to the first synchronous pulley 111 via a flat key, efficiently transmitting power to the synchronous belt 113 transmission system. The second synchronous pulley 112 optimizes the conversion of speed and torque, driving the peeling head 109 to rotate at high speed. The sealing ring design between the drive shaft end cap 115 and the clamping rod 203 acts as a reliable "protective barrier," effectively preventing lubricant leakage and ensuring long-term lubrication of the transmission components. The drive shaft end cap 115 is fixed to the right side of the sliding support 102 with four screws, further enhancing the overall sealing and structural strength of the device. Through the scientific and rational connection and cooperation between its components, the entire device achieves precise execution of the battery peeling operation, not only improving peeling efficiency and quality but also reducing equipment failure rate and extending service life through a stable mechanical structure design, providing a solid guarantee for the continuity and reliability of battery processing and production.

[0045] like Figure 2 As shown, the slide rod 101 is vertically inserted into the slide table base 117 from the left side, and the slide rod 101 is fixed horizontally by the slide rod fastening bolt 118; the sliding support 102 is connected to the slide rod 101 through the linear bearing 119, realizing the horizontal feed movement of the sliding support 102; the slide table base 117 is mounted on the slide table base plate 120, and the slide table base plate 120 and the slide table base 117 are welded and fixed; the slide table base plate 120 is fixed to the control system box 4 with four screws; the clamping rod 203 passes through the fastening nut 207 from the right side, and after being adjusted to a suitable clamping distance, the clamping rod 203 is horizontally fixed by the fastening nut 207 to restrict its horizontal movement; the bearing baffle 121 is installed on both sides of the sliding support 102 to fix the linear bearing 119.

[0046] In this embodiment, a stable and efficient horizontal feed system is constructed during the tool's forward and backward feed motion. After the slide rod 101 is vertically inserted into the slide table 117, the slide rod fastening bolt 118 secures it horizontally with a reliable mechanical locking method, making it the reference support axis for the entire feed motion. The sliding support 102, through the precise cooperation between the linear bearing 119 and the slide rod 101, achieves low-friction, high-precision horizontal linear feed, ensuring the smoothness of the motion and the accuracy of positioning. The slide table 117 and the slide table base plate 120 are rigidly connected by welding, greatly enhancing the structural strength. At the same time, the slide table base plate 120 is fixed to the control system box 4 by four-point screws, ensuring a stable connection between the feed device and the control system and guaranteeing operational coordination. After the clamping rod 203 passes through the fastening nut 207, it can be flexibly adjusted to a suitable clamping distance. The fastening nut 207 then plays a limiting role, preventing displacement in the horizontal direction and ensuring the stability and reliability of the clamping operation. Bearing baffles 121 are symmetrically installed on both sides of the sliding support 102, firmly fixing the linear bearing 119 and preventing it from shifting or loosening during operation, further improving the overall reliability of the device. The entire feeding device, with its rigorous connection logic and complementary functions among components, not only achieves precise and controllable horizontal feeding movements, but also effectively improves the load capacity and anti-interference performance of the device through enhanced structural design and reasonable fixing methods, laying a solid foundation for the continuous and stable operation of the equipment.

[0047] like Figure 1 As shown, the battery peeling machine also includes a control system box 4 and an outer casing recycling device 5. The control system box 4 is located below the sliding support 102 and contains a control module for controlling the operation of the battery peeling machine. The outer casing recycling device 5 is located below the battery peeling working area and is used to collect the peeled battery casing.

[0048] In this embodiment, the control system box 4 includes a plastic handle, a cabinet door, a box support base, and a box body. The plastic handle is fixed to the cabinet door with screws; the cabinet door is connected to the box body via hinges; four box support bases are vertically installed on the lower side of the box body and are connected to the box body with screws. Adjustable mechanical limit blocks and proximity sensors cooperating with the mechanical limit blocks are provided at both the start and end points of the sliding support's stroke. The various components of the control system box 4, through ingenious assembly design, constitute a fully functional and structurally robust control unit. The plastic handle, tightly connected to the cabinet door with screws, not only provides a convenient point of leverage for opening and closing the door, but its plastic material also has insulation and anti-slip properties, improving operational safety and comfort. The cabinet door is flexibly hinged to the box body via hinges, achieving multi-angle opening and closing, facilitating the inspection and debugging of the control components inside the box, and also forming a reliable protective barrier when closed, effectively resisting the corrosion of internal precision components by dust and moisture. Four support bases are vertically fixed to the underside of the enclosure, forming a rigid connection with screws. This creates a stable quadrilateral support structure, evenly distributing the weight of the enclosure and enhancing its stability during placement. It also provides space at the bottom of the enclosure for cable routing and heat dissipation. This design ensures the safe operation of internal components while also balancing ease of human-machine interaction and installation stability, providing a solid guarantee for the efficient realization of the overall equipment control functions.

[0049] In this embodiment, the outer skin recycling device 5 includes a wheel frame, handle, wheels, a recycling bin, screws, and rolling bearings. The wheel frame and recycling bin are fixed together by welding. The wheels and wheel frame are connected by a connecting rod and rolling bearings, allowing for flexible rotation of the wheels. The handles are connected to the recycling bin by welding and are fixed to both sides of the bin body, which is a welded structure. Through the scientific and reasonable connection and structural design of its components, the outer skin recycling device 5 forms a flexible, efficient, stable, and durable recycling system. The wheel frame and recycling bin are rigidly connected by welding, which provides excellent stability to the overall structure of the device, ensuring that it is not easily deformed or damaged when bearing the weight of the recycled materials. The wheels are connected to the rolling bearings and wheel frame by connecting rods. The use of rolling bearings significantly reduces the frictional resistance when the wheels rotate, allowing the wheels to turn and move flexibly and smoothly, easily propelling the device even under full load. The handles are firmly fixed to both sides of the recycling bin by welding, providing operators with comfortable and stable points of force for easy control of the device. The symmetrical design ensures balance and stability during the pulling process. As a welded structure, the recycling bin not only boasts excellent sealing to prevent spillage, but also enhances its strength and durability through a one-piece molding process, enabling it to withstand wear and impact from prolonged and frequent use. This outer casing recycling device 5, through the coordinated operation of its components, meets the needs for convenient mobility and efficient recycling, while its robust and reliable structural design significantly extends its service life and reduces maintenance costs.

[0050] In this embodiment, the method for peeling the 18650 battery includes the following steps:

[0051] S1: The clamping cylinder 205 in the clamping device 2 drives the clamping block 206 to rise, so that the clamping mouth 202 abuts against the clamping block 206. The horizontal position of the clamping rod 203 is adjusted so that the battery 6 is axially clamped and fixed from both ends of the battery 6. The position of the clamping rod 203 is locked by the locking structure 204.

[0052] S2: After the battery 6 is fixed, start the motor 104 to drive the peeling knife 108 to rotate, and start the feed cylinder 103 to push the peeling knife 108 to feed linearly towards the battery 6.

[0053] S3: The outer casing of the battery is peeled off by the linear feed motion of the rotating peeling blade 108;

[0054] S4: After peeling is completed, the feed cylinder 103 drives the peeling knife 108 to retract, the motor 104 stops, and the clamping cylinder 205 drives the clamping block 206 to fall back, which can loosen the clamping nozzle 202 to replace other batteries to be peeled.
