The Hwashi CCD Industrial Camera Housing Fully Automatic Circular Seam Welding Machine is a high-precision resistance seam welding system engineered specifically for the mass production of CCD industrial camera enclosures. By integrating CCD vision-based alignment, servo-driven rolling, and precision resistance welding into a single automated workflow, this machine eliminates manual intervention and delivers weld seams with sub-0.02mm repeatability — meeting the exacting dimensional and cosmetic standards required by industrial vision equipment manufacturers.

As part of Hwashi's Industry-Specific Welding Platform (行业应用专机), this solution leverages 25 years of resistance welding expertise and 100+ proprietary patents to serve the rapidly growing CCD/CMOS industrial camera market — where housing integrity directly impacts optical alignment, IP rating compliance, and long-term reliability.

• Detection accuracy: ±0.01mm — industrial CCD camera locates seam position in real-time before welding
• Repeat positioning accuracy: ≤±0.02mm — servo motor + ball screw / linear motor drive ensures micron-level consistency
• Automatic edge detection and seam tracking compensate for upstream forming tolerances
• Eliminates the need for custom fixtures per housing variant — CCD system auto-identifies part geometry

• Integrated workflow: auto-load → CCD inspect → roll-form → seam weld → unload
• PLC + PC dual-control architecture with HMI touch screen for recipe management and traceability
• Servo-driven rolling ensures uniform speed and pressure throughout the circular seam
• X-axis stroke: 300mm / Y-axis stroke: 200mm — accommodates a wide range of camera housing diameters and lengths

Automated Production Process:

Step 1: CCD Inspection

Step 2: Auto Plate Feeding

Step 3: Auto Roll-Forming

Step 4: Auto Seam Welding

Step 5: Auto Unloading

• Hermetic seam weld meets IP65/IP67 enclosure sealing requirements
• Minimal heat-affected zone preserves housing dimensional accuracy and surface finish
• No spatter, no oxidation discoloration — critical for the clean cosmetic appearance of camera housings
• Weld consistency enables downstream processes (lens mounting, sensor calibration) without rework

• CCD vision system automatically recognizes different housing sizes — no mechanical adjustment needed
• Parameter recipes stored for instant product changeover (ideal for mixed-model production)
• Compatible with aluminum, stainless steel (SUS304/316), and coated steel housings
• Table max load: 10 kg — suitable for both small camera bodies and larger lens barrel assemblies

• Rated power: ≤5kW — significantly lower energy consumption vs. laser or TIG alternatives
• Forced water cooling on transformer and weld wheels for high duty cycle operation
• Single-operator supervision — load/unload only, all welding parameters auto-controlled
• Compact footprint: 1,850 * 1,500 * 1,910 mm
