Learn how custom robot housings and protective enclosures are designed and fabricated to shield industrial robots from harsh factory environments while maintaining accessibility and safety.
Introduction
Industrial robots represent significant capital investments, and their housings and protective enclosures play a crucial role in ensuring their longevity and performance. Robot housings must protect against dust, coolant, oil mist, temperature extremes, and physical impact while providing access for maintenance and programming. At Fulei Metal, we fabricate robot housings and protective enclosures for clients in automotive, electronics, and general manufacturing industries.
Robot Housing Functions
Robots operating in industrial environments face exposure to metal dust, coolant mist, oil spray, and welding spatter. Housings must prevent these contaminants from reaching sensitive robot components. Robots generate heat during operation, requiring housings with ventilation systems, fan mounts, or air conditioning integration. Robot housings must provide safe access for programming, maintenance, and emergency intervention, with access doors featuring safety interlocks meeting ISO 10218 standards.
Housing Types
Full enclosure housings completely surround the robot, used in harsh environments such as machining centers and foundries. Partial covers protect specific robot components such as wrist assemblies and cable bundles. Collaborative robot guards define the collaborative workspace and protect personnel, meeting ISO/TS 15066 standards.
Material Selection
Cold-rolled steel is standard for general industrial applications (1.5 to 2.5 mm). For food processing, pharmaceutical, and corrosive environments, stainless steel housings provide superior corrosion resistance and hygiene. Aluminum housings are used in portable robot systems or robots mounted on overhead tracks.
Fabrication Process
Our TRUMPF fiber laser cuts housing panels, frame components, and mounting brackets with cutouts for cable entries, ventilation, viewing windows, and access panels. CNC press brake machines form complex geometries including return flanges, stiffening ribs, and gasket grooves. Housing frames are TIG or MIG welded, with continuous welds for sealed joints. Our assembly team installs hinges, locks, gaskets, windows, fans, filters, and cable management systems.
Field Notes: Robot Cell Housings and Guards
A robot cell housing is a safety structure before it is a sheet metal product, and the safety requirement changes the fabrication. Guards have to hold a defined clear opening so that a hand cannot reach through while the cell is running, which means the aperture size and the distance from the aperture to the hazard are both dimensions rather than details. Panels are then stiff enough that impact does not deflect them into the opening, and access doors are interlocked rather than merely latched. On the fabrication side the practical difficulties are panel flatness – a large welded guard panel pulls out of flat, and a bowed panel leaves a gap at the frame – and edge condition, because a guard is handled during maintenance and a laser cut edge on 2 mm steel will cut.
Conclusion
Industrial robot housing fabrication requires understanding of robot operation, environmental protection, and safety standards. Fulei Metal’s engineering expertise and manufacturing capabilities deliver robot housings that protect automation investments and reduce maintenance costs.
