With the development of Industry 4.0, the intelligent level of the production line of high-speed smart home enterprises has been continuously improved, and the processes of cutting, edge banding, drilling, sorting, spraying, and packaging have been integrated to achieve a real "unmanned factory".
Intelligent and flexible production equipment allows robotics and machine vision to shine in the industry, especially in the spraying process. This process is a very important process in the later stage of wooden door manufacturing, and the quality of spraying directly affects the production efficiency and final quality of wooden doors. The automatic spraying system from SICK partners is an intelligent control system that integrates 3D vision, manipulator, and spraying motion control. The system can effectively replace the shortage of labor, improve production efficiency and spraying quality, and can also cooperate with the spraying control system to greatly increase the proportion of effective gluing, save spray costs, and make enterprise production more environmentally friendly.
1. Application description
The traditional manual and mechanical reciprocating spraying stations have problems such as uneven quality of spraying products, difficulty in recruiting excellent technicians, large spray waste, and high cost.
The system customizes automatic spraying intelligent equipment according to customer needs, combines 3D vision with manipulator, and installs it on the wooden door spraying process equipment: wooden doors of different shapes, thicknesses, and positions can obtain complete three-dimensional images by scanning by SICK 3D vision cameras, and generate manipulator coordinate information through automatic trajectory system algorithm processing, guide the manipulator to evenly spray the wooden door, track the operation online, replace traditional manual spraying, reduce spraying costs, improve production quality and efficiency, and assist enterprises in formulating more controllable, Manufacturing practices with more consistent quality.
The specific parameters are as follows:
1. Objects to be measured: wooden doors, doors and windows, desktop panels, cabinet doors, etc.;
2. The speed of the conveyor line can reach 20m/min;
3. The detection accuracy of equipment size can reach 0.1mm
2. Application difficulties
There are many types of products, complex shapes, and changeable colors, which have high requirements for the imaging effect of 3D cameras
The field of view is large and the cycle time is faster
3D vision + manipulator + spraying motion control requirements are high
3. Scheme selection
Ranger3 and Ruler3120 with M30 sensor from SICK for high speed and precision: up to 2560 X pixels and up to 46 kHz (ROI mode: 128 rows)
The Ranger3 is a split camera that can be flexibly adapted to different lenses and light sources according to the size of the sheet compatible with the production line
The all-in-one Ruler3120 is factory calibrated for ease of use and is a quick configurator for integrators
