Introduction

Interpretation of the core content of the standard

GB/T41264-2022 is my country's first safety standard specifically for sheet metal bending robots, which builds a complete technical framework from hazard source identification, safety protection to verification methods. The standard is applicable to two types of robots: rectangular coordinate type and articulated type, and focuses on standardizing safety requirements under typical working conditions such as material picking, positioning, and bending following.

Analysis of key safety requirements

Safety dimension	Technical requirements	Implementation points
Control system	Fault detection, alarm and safety state maintenance must be realized	Dual-channel safety circuit design should be adopted
Space limitation	Three-level protection: software limit → limit switch → anti-collision block	The distance between hard limit and soft limit ≥50mm
Operation mode	Physical isolation of teaching/playback/automatic three modes	Key switch requires mechanical interlock

Technical innovations

Bending follow-up safety: The standard clearly requires for the first time that the robot must have the rear stop finger displacement deviation detection function (5.7.2f clause), and when the detection value difference is ≥0.2mm, the protection stop should be triggered. A case study of an enterprise shows that this requirement can reduce 40% of workpiece collision accidents.

Electromagnetic compatibility: Clause 5.14 stipulates that the robot must operate stably in a typical sheet metal workshop environment (including welding equipment interference), and it is recommended to adopt a three-level filtering solution: power input + driver + communication line.

Implementation suggestions

Safety space planning: The collaborative workspace should avoid the robot's motion path (Clause 5.17.4). It is recommended to retain an observation channel of ≥500mm.
Verification process: The full process test of the three modes must be completed during the trial operation phase (Clause 7.2). It is recommended to prepare a "Safety Function Checklist".
Maintenance points: Check the air path sealing every month (Clause 5.12.7). Test the ESPE light curtain response time every quarter.
