2.1 Stationary Pneumatic Electrode Cap Changer

Stelon pneumatic cap changer adheres to German-style precision manufacturing philosophy, specially designed for the electrode dressing process of resistance spot welding, realizing automatic removal and installation of electrode caps. Equipped with a mature pure pneumatic drive system and high-precision mechanical positioning structure, it can be directly docked with industrial robot workstations, continuously delivering stable and accurate cap changing operations in high-cycle automotive body welding production, ensuring consistent welding quality and reducing production operation and maintenance costs.

Description

Core Performance Advantages

 

  • High-Precision Cap Changing with One-Time AlignmentAdopting a coaxial positioning and clamping mechanism, the accuracy of cap removal and installation is controlled within ±0.05mm. The electrode cap is installed without deflection or loosening, and can be directly put into production after cap changing, without manual secondary adjustment.
  • Pure Pneumatic Structure for Harsh Workshop EnvironmentsThe whole machine uses compressed air as the sole power source, without complex electrical control units. It has excellent dust-proof and anti-interference performance, and can operate stably for a long time under dusty and high-humidity working conditions in welding workshops, with low failure rate and long service life.
  • Modular Design for Convenient and Efficient MaintenanceThe cap removal unit, cap installation unit and cap magazine all adopt a modular structure. Wear parts can be replaced easily and quickly without professional tools. The large-capacity cap magazine design reduces refilling frequency and minimizes equipment downtime.
  • Full Specification Compatibility with Customized AdaptationCompatible with full series of standard electrode caps such as φ12, φ13 and φ16, and can match mainstream domestic and foreign brands of spot welding guns and robots. Customized solutions are available according to customer’s station space, production cycle and welding gun model, realizing seamless integration into existing production lines.

Closed-Loop Dressing Process Support

  • This equipment can be combined with an electrode dresser to form an integrated dressing and cap changing workstation. With robot programming, it realizes full-process automation of electrode dressing → life assessment → automatic cap changing → production resumption, forming a complete closed-loop electrode maintenance process, which is a standard supporting unit for automated welding workshops.

Application Fields

  • Automotive body-in-white (BIW) welding production lines
  • Auto parts spot welding stations-
  • Automated welding for home appliance sheet metal-
  • Resistance spot welding scenarios for hardware products
