Automatic Laser Stripping Machine for 18650 Cylindrical Battery Casings

I. Equipment Overview

1.1 Equipment Application

l Intended for stripping the outer casing of 18650 cylindrical batteries.

1.2 Equipment Operation Flow

1.3 Equipment Diagram

Overall Dimensions

l Laser Stripping Unit: 200 cm × 75 cm × 180 cm (L × W × H)

l Automatic Boxing Unit: 100 cm × 70 cm × 180 cm (L × W × H)

l Note: Dimensions are subject to the actual equipment.

Equipment Weight

l Total weight: approx. 1000 kg

1.4 Main Module Descriptions

1.4.1 Manual Battery Loading into Feed Hopper

l Operator places batteries into the hopper; a feed wheel dispenses batteries into the chain conveyor.

1.4.2 Motor-Driven Chain Conveyor

l Stepper motor drives the chain to feed batteries one by one.

1.4.3 Laser Circumferential Cutting of Battery Heads

l Pressing mechanism holds the battery and rotates it; laser beam cuts the heads of 5 batteries simultaneously.

1.4.4 Rotary Transfer Mechanism

l Mechanical arm grabs 5 batteries, reorients them, and places them onto the second chain conveyor.

1.4.5 Dual-Side Laser Cutting

l Laser beam cuts two straight lines on each battery, centered on the body.

l Two parallel chain tracks enable simultaneous head cutting and side cutting.

1.4.6 End-Face Scrap Removal Mechanism

l Cylinders push 5 batteries into the scrap removal unit, where heads are clamped;

rear cylinders push batteries back to the track, discarding the head scrap;

scraps are collected in a bin under the workbench.

1.4.7 Steel Shell and Outer Film Separation

l Rubber plates position batteries top and bottom, increasing friction;

steel shell is pushed out for separation, leaving waste film on the track;

waste is carried down with the chain and collected in a bin under the workbench.

1.4.8 Inclined Plate Discharge

l Separated steel shells are discharged via a 1000 mm long inclined plate.

1.4.9 Automatic Boxing

l Automatically loads processed batteries into collection boxes.

1.4.10 Laser Section Enclosure with Exhaust Fan

l Laser cutting section is enclosed and equipped with exhaust ventilation.
