Product Description

Product Description

Telecentric F-theta Scan Lens

Telecentric F-Theta scan lens is a special type of lens system whereby the deflected off-axial laser beam can be perpendicularly focused to work piece as similar to the on-axial focusing beam. The advantage of the telecentric scan lens is that it is able to flatten the field curvature to the least distortion and yet offering superb spot quality throughout the scan field. For high power laser and ultrafast laser source, we offer TSL-Q Series Telecentric F-Theta Scan Lens to minimize thermal lensing and focal shift.

Applications

The F-theta telecentric scanning lens is used as a power battery welding lensapply to Laser Processing on Power Batteries.

Operation principle and application

1. Laser cutting on polar ear

There are four types battery materials:

1) NiMH batteries, 2) fuel battery, 3) lead-acid batteries, 4) lithium electronic batteries.

The production of lithium batteries is a "roll-to-roll" process, whether it is lithium iron phosphate, sodium ion, or ternary batteries, all need to go through the process from thin film to individual battery, and then mounted into a battery system. The lithium battery production process includes: electrode production, battery cell assembly, and packaging.

 

Lithium batteries are mainly composed of positive electrodes, negative electrodes, diaphragms, electrolytes and battery casings. laser is used to cut and form of positive and negative electrodes.

2. Laser cleaning on foil

The positive and negative electrodes of lithium batteries are made by coating with aluminum and copper foil, The foil needs to be cleaned before coating to obtain a completely clean and oxide free surface.

3. Laser welding on power battery

Laser welding process on power batteries includes welding, leak detection, short circuit detection and coding and marking. Different Pulsed laser will be used for welding according to battery material, thickness, and shape. Scan welding system consists of collimator, scanner, scan lens, objective lens, CCD, dichroic mirror, connecting plate and air knife etc.
