In the era of high-speed lithium battery stacking, bid farewell to the pain points of ultrasound! Atorm MDSC-2102L one to two dual detector adapted for mainstream high-speed production lines

The demand for drones and 3C consumer electronics continues to rise, and the production capacity requirements for lithium batteries are constantly increasing. The operating pace of laminating machines is also getting faster and faster. As an essential safety process on the laminating machine, the selection of the double sheet detection scheme for lithium battery laminating machines directly affects the stability of the production line and the safety of high-quality products.

There are still many equipment manufacturers using ultrasonic dual sheet testing. But ultrasound has a clear weakness: it relies on the air gap between the two polar plates as the basis for identifying double sheets. Once the polarizer is tightly adhered and bonded without gaps due to static electricity, it is difficult to identify delamination and is prone to missed detection.

It should be noted that ultrasound still has irreplaceable value in the detection of non-metallic layers such as diaphragms and tapes; But the copper aluminum foil double sheet of the polarizer itself is essentially a change in metal thickness/eddy current loss. Directly measuring metals using eddy currents is one less physical variable than indirectly inferring air gaps using sound waves, resulting in one less failure step.

AtonmMDSC-2102L Stacker Double Sheet Detector(One to two single probe dual sheet detection), using the principle of eddy current detection, targeted to solve this pain point, suitable for mainstream high-speed lithium battery laminating production lines:

1. The probe is compact and suitable for small shaped pole pieces

M12 specification probe, compact in size. 3C、 The commonly used ultra narrow and irregular pole pieces for drone batteries are also easy to arrange in narrow workstations, and are not easily interfered with by suction cups, brushes, and shaking mechanisms.

2. Single side installation, time-saving and easy to debug; One to two, calculate by workstation

Unlike ultrasound, which requires a pair of probes to be aligned and installed, this model only requires one probe to be arranged on one side, with simple wiring and no need for repeated alignment and calibration, helping equipment manufacturers save installation and debugging time. In a dual station scenario, a controller with two probes reduces the number of controllers by half, as well as the power and communication wiring by half. This results in a synchronous decrease in BOM costs and integration hours - not just an additional channel, but a system level cost reduction calculated by the number of workstations.

3. Fast response and keeping up with mainstream high-speed beats

The hardware response of the sensor is about 50ms, and the detection cycle can reach about 1200 times/minute. It is designed for the feeding cycle of mainstream high-speed laminating machines, without slowing down production capacity. The dual signal is kept locked to avoid alarms flashing and recording omissions under short signal windows, and to truly convert "detected" into "intercepted".

4. Not afraid of electrode sticking and adhesion, more stable detection

Eddy current testing detects changes in the conductivity characteristics of copper aluminum electrode plates themselves, without the need for gaps between the two electrode plates. Even if the polar plates are electrostatically adsorbed and tightly attached together, they can still distinguish whether they are single or double sheets, effectively intercepting abnormal materials. Brushing, blowing, and shaking are only pre splitting methods, and cannot guarantee 100% separation of the polarizer. The dual detector is the last line of defense for the laminating production line.

Atorm MDSC-2102L dual sheet inspection for electrode overlap detection fills the gap in the ultrasonic solution for electrode overlap detection, making it the preferred domestic dual sheet inspection solution for mainstream high-speed lithium battery laminating machines.
