Semi-Auto Cylindrical Cell Winding Machine (5-10PPM)

Semi-Auto Cylindrical Cell Winding Machine (5-10PPM) Ⅰ、Equipment Function Description This machine is mainly used for precision winding of cylindrical lithium ion battery cells. The working process is as follows: manually guide the positive and negative plates into the winding part respectively, stack them with the diaphragm, wind them according to the process requirements, automatically attach the termination tape, and the cell is automatically cut. Ⅱ、Equipment Functions and Features 1) Single target threading needle structure is adopted. 2) Manual introduction of pole piece, automatic winding, automatic needle change, automatic pasting of termination tape and automatic blanking. 3) The adhesive tape is pasted horizontally (the termination tape is perpendicular to the pole ear), the adhesive tape is flat, and the adhesive position can be accurately controlled without straining the electric core; Glue sticking is stable and reliable. 4) The winding speed of winding needle is adjustable. 5) Active unwinding of two coil diaphragm, tension proximity switch control technology, which can automatically and smoothly adjust the tension in the winding process; The upper and lower tension can be adjusted. 6) Closure of diaphragm outsourcing. 7) The rolled out electric core shall be free of damage, core pulling and pole dislocation. 8) Easy operation, simple and fast adjustment and replacement of specifications. Ⅲ、Technological Process The equipment meets the winding process standard of cylindrical lithium-ion battery: the diaphragm completely wraps the negative sheet, and the negative sheet wraps the positive sheet. The process flow is as follows: 1) Diaphragm pre coiling: Adopting tooth cutter technology can save the length of pre coiling diaphragm; 2) Draw in the negative electrode: Manually guide the negative electrode sheet into the winding part;Draw in the positive electrode: Manually guide the positive pole piece into the winding part; 3) Winding; 4) Shift station; 5) Cut off the diaphragm, paste the termination glue and blanking.   D W L Tolerance(mm) < 0.5 < 0.3 < 1000   Ⅳ、Main Components of Equipment 1) The equipment is composed of winding device, station changing device, diaphragm unwinding device, pole piece guide device, glue pasting device, blanking device and control system. 2) Winding device (two sets): Composed of single head opposite threading to ensure winding accuracy and convenient replacement of winding needle. 3) Station moving device (one set): Used for the conversion of winding station and gluing station. 4) Diaphragm unwinding device (two sets): Diaphragm coil active unwinding air pressure regulation control. 5) Pole piece guide device (two sets): Unilateral adjustment, convenient adjustment. 6) Gluing and blanking device (one set).   Ⅴ、Technical Standard 1) Diaphragm width: 30-75mm; Coil needle specification:∮1.8-∮6.0 mm, customized according to customer requirements; Pole width: 28-73mm. 2) Material specification requirements (unit: mm) Material Length Width Thickness Internal Diameter External Diameter Positive Electrode 150-1000 28-73 0.1-0.2     Negative Electrode 150-1000 28-73 0.1-0.2     Seperator Material Roll 30-75 0.012-0.045 76.2 250 Termination Tape Material Roll 8-60 0.01-0.035 76.2 150 3) Applicable outer diameter of electric core (mm -∮20mm) 4) Equipment capacity: 5 ~ 10 pieces/min (according to pole piece length/width) 5) Winding accuracy;  When ensuring that the pole piece meets the following conditions: The width error of the pole piece is less than±0.2mm; The "S" bending error of the pole piece is less than±1mm/500mm; The tower shape error of diaphragm coil is less than±0.2mm; The winding accuracy can meet: The diaphragm alignment error is less than±0.5mm; The alignment error of pole piece is less than±0.5mm; It can realize the alignment of negative electrode wrapped with positive electrode and diaphragm wrapped with negative electrode, and the section of finished product is ±0.5mm. 6) Qualified rate: ≥98% (Excluding non equipment factors).   Ⅵ、Specification Parameters   Specifications Remarks Input Power AC220V,1.5KVA,50HZ   Compressed Air Source 0.4-0.6MPa   Production Capacity of Equipment 5-10PCS/min According to model and employee proficiency Equipment Weight About 500kg   Equipment Size 1450mm*1100mm*1150mm (L*W*H) Excluding the extension length of pole piece material groove, unit:mm Coil Needle Specification ∮1.8mm-∮6mm Deliver one set according to customer requirements Rack and Mounting Plate 1 set   Needle Winding Device 1 set   Pole Piece Supply Device 2 sets   Diaphragm Supply Device 2 sets   Viscose Device 1 set   PLC PANASONIC PANASONIC AFRX-C60T Touch Screen MCGS 7-inch true color Winding Motor PANASONIC/Li San Panasonic servo motor Tension Motor Research Control / Li San Stepper motor Sensor PANASONIC/Daochuan   Pneumatic Components AIRTAC/XINGZHEN/ AirTAC   Fault Stop Fault Prompt Program Built In One Touch Reset Operating Instructions 1 set of operating instructions   Parts 1 set See delivery list   Name Specification (mm) Warranty Time Remarks Winding Machine   Complete machine 1 year Except for human factors (Lifelong maintenance) Gummed Paper Cutter   3 months   Rolling Needle   3 months Except for human factors Photoelectric Eye   6 months Crash and oil inlet are not guaranteed Synchronous Belt   1 year Oiling is not guaranteed  

Fully Automatic Winding Machine for Cylindrical Cell Production

TMAX-YS-BYZ65 is an automatic winding machine for accurate assembly of cylindrical battery electrode cores (also known as “jelly roll”). Using this machine, cathode and anode films, separated by top and bottom separator films, are rolled up into a hollow cylinder casing for cylindrical battery applications. It is an ideal tool for reliable and precise production of high quality windings of electrode cores.
