Compact gas-electric slip rings developed specifically for lithium battery production equipment

As lithium battery production lines evolve toward greater speed, precision, and automation, the demand for compact, high-performance slip rings capable of handling multiple media in limited spaces is skyrocketing. Jinpei Electronics proudly introduces its latest breakthrough: a compact pneumatic-electric slip ring tailored for next-generation lithium and new energy battery equipment.

In automated lithium battery manufacturing—such as cell winding, electrode stacking, and laser welding—rotating platforms must transmit power, signals, and vacuum or compressed air simultaneously. Conventional rotary solutions often struggle with bulk, complexity, or poor reliability under these demanding conditions.

JINPAT's new model offers a compact, integrated solution that meets the specific technical challenges of these applications:

• Vacuum-compatible up to -30 kPa

• 5 power circuits rated at 30A each

• 1 Gigabit Ethernet channel for high-speed industrial communication

• 2 pneumatic passages for vacuum/air operation

• Low starting torque & minimal mechanical resistance

• Ultra-compact form factor, ideal for limited installation space

  

  
  

This integration allows battery equipment manufacturers to design tighter, faster, and more intelligent production lines without sacrificing transmission performance or stability.

Unlike generic slip ring offerings, this model is the result of dedicated R&D in electro-pneumatic hybrid transmission, with key innovations including:

1. Precision-machined rotary interfaces to ensure signal integrity and media isolation

2. Low-friction structural design, reducing torque and extending equipment life

3. Optimized channel layout, minimizing crosstalk between power, data, and air circuits

4. Reinforced insulation and shielding, protecting sensitive signals even in high EMI environments
