Grinding robots are mainly used for high-precision grinding and polishing operations in the electronics industry, cell phone shells, automotive parts, industrial parts, medical equipment, civil products and other industries. When companies carry out robotic polishing, often in the following aspects of the characteristics of the advantages:
1. Stabilize and improve the quality of grinding and product finish, to ensure its consistency;
2. Increase productivity, a day can be 24 hours of continuous production;
3. Improve the labor conditions of the workers, can be in the harmful environment for a long time;
4. Reduce the requirements for workers Reduce the requirements for workers to operate the technology;
5. Shorten the cycle of product modification and replacement, reduce the corresponding investment in equipment;
As the saying goes, there are specialties in the industry, robotic sanding or to look at professional sanding robots. Professional sanding robot is mainly composed of industrial robot body and flexible force control sanding tools, grippers and other peripheral equipment, through the system integration, by the total control cabinet will be connected to the robot and peripheral equipment hardware and software, unified coordination, to achieve a variety of sanding functions.
There are two main ways of robot sanding: one is through the robot end-effector clamping force-controlled sanding tool, active contact with the workpiece, the workpiece is relatively stationary, so this sanding robot can be called a tool-active sanding robot; flexible force-controlled sanding tool force control system according to the needs of the work of the untouched tool for gravity compensation and the precise output of the axial parallel to the arm of contact force, while the device can also be based on the contact surface, and the contact force can be adjusted according to the work of the robot, and the contact force can be adjusted according to the contact surface. At the same time, the device can also adaptive expansion and contraction according to the wheel gallery characteristics of the contact surface, solving the automation problem between the contact surface sensitive characteristics of the process and rapid contact movement. The robotic system controls the sanding path, and the force control system is flexible and constant force output, which not only can make every part of the substrate surface be treated in place with high consistency, but also with higher sanding efficiency. The force control precision of the flexible force control sanding tool reaches an amazing 1N, which is a very small force, with a finger gently touching the table, at least 2-3N force, this force control precision is much higher than the precision of human hands. If the robot does not use the flexible force control sanding system, but directly grasps the sanding tool to sand, due to the inability to control the sanding strength, also can not carry out flexible floating, sanding yield is very low; and on the robot alignment accuracy, debugging process requirements are very high, debugging is very troublesome. The flexible force control sanding system of Yinglian Technology can automatically carry out flexible control in less than 0.01 seconds by real-time perception of key information such as force, position and posture to ensure constant sanding force.
The other is the robot end-effector clamping workpiece, through the workpiece close contact with the flexible force-controlled belt sander, the equipment is relatively stationary, so this sanding robot is also known as the workpiece active sanding robot. Flexible force-controlled belt sander with force-controlled flexible polishing and sanding tools, also with force / position hybrid control compensation, precision force and position control technology to ensure that the contact force is accurate and stable, but also according to the process of automatic compensation for wear and tear of the abrasive belt consumables, and sanding wheels and consumables are very easy to dismantle and replace the late maintenance costs are also very low.
