The horizontal requirements for the installation of automation equipment should be based on the current national standard GB/T 50231-2016, combined with the clear control threshold of equipment functions and accuracy levels. The core goal is to ensure operational accuracy, balance loads, and reduce mechanical wear and vibration
1, General Control Basic Requirements
(1) Measurement and benchmark requirements
1. The measuring tool needs to match the accuracy level: high-precision equipment uses an electronic level with a precision of 0.02mm/m, while ordinary equipment can use a frame level with a precision of 0.05mm/m;
2. The installation reference surface needs to be cleaned of oil stains and burrs, and the initial horizontal deviation of the foundation platform needs to be retested to ensure that there is no hidden danger of settlement and deformation of the foundation.
(2) Universal deviation threshold
1. Light load low-speed auxiliary equipment (such as ordinary material racks and simple roller conveyors): horizontal deviation ≤ 0.5mm/m;
2. Medium speed general equipment (such as servo conveyor lines and packaging equipment): deviation ≤ 0.2mm/m;
3. High precision specialized equipment (such as PCB drilling matching loading and unloading devices, semiconductor packaging equipment): deviation ≤ 0.05~0.1mm/m, ultra precision equipment needs to be ≤ 0.02mm/m.
2, Special level requirements for equipment types
(1) Linear conveying equipment
1. The horizontal deviation at the beginning and end of the entire line is ≤ 0.3mm/m, and the deviation at the base of the single section conveyor unit is ≤ 0.2mm/m, to avoid belt deviation and material jamming;
2. Double side guide rail conveying equipment, the horizontal difference between the two side guide rails should be ≤ 0.1mm/m to prevent one-sided load overload from exacerbating guide rail wear.
(2) Sports execution equipment
1. The horizontal deviation of the industrial robot installation base is ≤ 0.1mm/m, and the contact rate between the base and the foundation is ≥ 90%, reducing vibration transmission;
2. The installation horizontal deviation of the dividing disc and rotating worktable should be ≤ 0.08mm/m to avoid exceeding the radial runout during rotation.
(3) Precision homework equipment
1. The horizontal deviation of the working surface of visual inspection and automatic screw locking machine should be ≤ 0.05mm/m to prevent detection angle deviation and lock hole alignment error;
2. The installation base of the vibration feeding equipment needs to be equipped with vibration damping pads, with an overall levelness of ≤ 0.3mm/m, to avoid feeding jamming.
3, Requirements for retesting and adjustment after installation
1. It is necessary to retest the levelness after tightening all fixed bolts to prevent deformation and deviation during the tightening process;
During the trial operation phase, it is necessary to recheck the changes in levelness. If there is a deviation exceeding the tolerance, it is necessary to investigate the problems of foundation settlement and uneven load, and correct the deviation by adjusting the height of the shim; Adjusting the pad iron operation must be completed by certified mechanical installers to avoid the risk of equipment overturning.
