A large number of tasks for assembling robots are the assembling of shafts and holes. Assembling in the presence of errors in the shafts and holes requires the robot to have flexibility in motion. Active compliance is to adjust the robot hand movement based on the information fed back by the sensor, while the driven compliance uses an unpowered mechanism to control the movement of the claw to compensate for its position error.
Assembly robots are mainly used in the manufacture of various electrical appliances, (including household appliances, such as televisions, tape recorders, washing machines, etc.), small motors, automobiles and their parts, calculators, toys, mechanical and electrical products and components. )
he assembly robot is the verification equipment of the flexible automated assembly system. It is composed of a robot manipulator, a controller, an end effector and a sensor system. The structure types of the robot include horizontal joint type, rectangular coordinates, multi-joint type and cylindrical coordinate type, etc.; control Generally, multi-CPU or multi-level calculator system is used to realize motion control and motion programming; the end effector is designed to adapt to different assembly objects into a variety of grippers and wrists, etc.; the sensor system is used to obtain the assembly robot and the environment and assembly Information used between objects.
Features of assembly robot:
1. Each assembly robot arm can be equipped with different tooling according to the process needs to meet the multiple batch and small batch production requirements of the future production line. It only needs simple programming and tooling replacement to achieve rapid switching.
2. The robot‘s high precision and operation stability can be used in lean industrial production processes.
3. The vision function guides the robot to correctly identify and grab the workpiece, and transfer it to the precise assembly position.
4. The robot has a high input-output ratio and a short equipment payback period.
