X/β-Ray multi-frame synchronous gauge system

X/β-Ray multi-frame synchronous gauge system is able to eliminate the effects of area density fluctuation of substrate and area density fluctuation of single coating film.

X/β-Ray multi-frame synchronous gauge system is able to eliminate the effects of area density fluctuation of substrate and area density fluctuation of single coating film.

High accuracy synchronous scanning

Synchronous scanning parameters

Trace error: ±3mm(Coating speed at 0~30m/min)
Trace error: ±5mm(Coating speed at 30~60m/min)

EtherCat bus structure

Industrial EtherCat bus structure, response time < 1ms

Auto trace error eliminating

Auto eliminating trace error on x/y direction caused by encoder.

Application

Double frame area density synchronous gauge system manufacturing application.

Powerful management software

1. Informative user interface, showing area density data of side A, side B and net coating
2. Support MES, uploading data automatically
3. Statistic function: CPK/Max/Min.

2nd frame data shows total weight less than specification, but no need to adjust coater parameters, since double frame synchronous gauge system detect that the fluctuation caused by copper foil not the coater.

Laser thickness gauge

Laser thickness gauge measure the thickness of electrode with high precision and non-destructive. Products of DCPRE such as coating-type/calendering-type laser thickness gauge are widely accepted by first-tier battery manufacturers, including ATL/BYD/LiSheng/A123 Battery etc.
