PRODUCT

Manufacture of secondary battery
production systems
_Packaging Machine

The process of making a unit cell by ultrasonic/laser welding, EL-filling, and sealing an aluminum pouch, lead tab, electrolyte, etc. of a battery laminated with a separator on an electrode and an anode.

Main Features

• High-speed : Application of high speed in-line method based on long width cell
- Minimize Cell Touch to Reduce Defect Rate and Maximize Transfer Speed
• Central Managed System
- Material and parts life management by unit (replacement cycle confirmation alarm)
• Tab Welding : Welding Horn & Envil, Tab Cutter
• Forming : Forming Press Mold, Slit Cutter, Pouch Cutter
• Cell Assembly : Sealing Bar, Measurement Probe
• EL-Filling : Nozzle, Electrolyte
• Vacuum Sealing : Sealing Bar
• Automation : Automatic input/replacement/discharge of raw material are configurable
• Smart Factory : Manual/Semi-Automatic/Fully Automatic : Possible to countermeasure according to the needs of customer

Equipment Process

Equipment Process

Equipment that welds and inspects leads on the negative / positive tabs of stacked electrodes.

Main Features

Laser applied lead tab welding
Possible of increasing welding strength by adding the number of laser hits and determining welding quality by adding the vision check function, compared to the existing ultrasonic welding.
LMS (Linear Motion System) / X-bot
Pitch operation (1~2) is free and high-speed movement is possible.

Unit Configuration

No Unit Remark
1 Cell Align stack finished cell after loading to alignment
2 Pre Welding Weld tabs with an ultrasonic welding machine
3 Tab Cutting Cut welded tab
4 Lead Welding & Tab Press Weld lead to welded tab with laser
5 Taping Attach protective tapes to welded surface
6 Tape Press Press the attached tape
7 Vision Inspection Inspect welded surface using vision

Equipment that unfolds roll-shaped pouches, form them according to the cell shape, and then discharges.

Main Features

Auto Pouch Law Material Reel Change
Pin Hole Check
Mismatch is prevented through pin hole oc clusion when combining upper and lower pouches.

Unit Configuration

No Unit Remark
1 Pouch Unwinder Unwind pouches
2 Slit Cutting Slit cut the middle part to adjust the expansion and contraction of pouches during forming
3 Pouch Holder Hold pouches during the mold press
4 Mold Forming Press Press with a mold to form in cup shape
5 Sheet Cutting Cut to fit the length of molded pouches
6 Pin Hole Check Mismatch prevention when connecting the upper and lower parts of pouches

Equipment that heats and seals the formed pouches by inserting electrodes into.

Main Features

Temperature equalization
Minimized sealing deviation by controlling the temperature of the sealing tool
LMS (Linear Motion System)
Pitch operation (1~2) is free and high-speed movement is possible.

Unit Configuration

No Unit Remark
1 Welded Cell In Input tab welded electrodes into the cell assembly process
2 Pouch Folding Fold and combine upper / lower pouches
3 Top/Side Sealing Apply heat to seal pouches
4 Vision Check Inspect dimensions after cell assembly
5 Cell Out Discharge cells to the next process

Process that injects electrolyte into the sealed pouches and then seals in a vacuum chamber.

Main Features

Measure weight before/after EL-filling
Measure weight before/after injection to determine the exact injection amount
