Description

Technical Field

[0001] The present invention relates to the technical field of collaborative robot arms, and in particular to a collaborative robot with an autonomous obstacle avoidance function. Background Art

[0002] Collaborative robots, including collaborative robotic arms, are typically robotic arms or grippers designed to safely interact directly with human workers in the same workspace. They are widely used in various industrial scenarios to assist humans in completing repetitive, precision-intensive, or physically demanding tasks.

[0003] Features of collaborative robots include: Safety: Equipped with sensors and soft materials to ensure that no harm is caused when in contact with humans. For example, it will automatically stop operating when an abnormal external force is detected. Easy integration and programming: Many collaborative robots can be programmed through an intuitive user interface, and some even support "teaching" action sequences through manual guidance, which greatly reduces the threshold for use. Flexibility: They can be quickly reconfigured and deployed to adapt to different task requirements, which makes them very suitable for high-variety, low-batch production environments. Compact design: Compared with traditional industrial robots, collaborative robots tend to be lighter and smaller, making them easy to install on existing production lines or workstations without the need for large-scale renovation projects.

[0004] Collaborative robots have a wide range of applications, encompassing not only assembly, welding, and handling processes in manufacturing, but also food processing, medical surgical assistance, and laboratory automation. With technological advancements, collaborative robots are becoming increasingly intelligent, capable of taking on more complex tasks while collaborating more closely and harmoniously with humans.

[0005] Existing collaborative robots usually need to move according to usage needs during use, but when moving in the factory, they are easily blocked by obstacles, affecting their movement. Existing collaborative robots usually have autonomous obstacle avoidance functions, which are usually achieved through millimeter-wave radar or vision systems. However, existing obstacle avoidance systems usually have blind spots.

[0011] Through the setting of the motion mechanism, the base can be driven to move through the setting of the motion wheel, thereby driving the collaborative hand to move, and through the setting of the visual recognition sensor, the motion path of the collaborative robot can be controlled by controlling the speed of the motion motor, thereby achieving a certain obstacle avoidance function; through the setting of the protection mechanism, when the collaborative robot moves, the mounting frame can be raised through the setting of the telescopic parts, thereby moving the four first protection plates upwards, and enclosing the collaborative hand between the four first protection plates, thereby avoiding collision with obstacles during the movement of the collaborative robot and avoiding damage to the collaborative hand.

[0012] Furthermore, the visual recognition sensor is an existing technology and will not be described in detail.

[0056] Furthermore, the visual recognition sensor is an existing technology and will not be described in detail.

[0057] like Figure 3 、 4As shown in , 6 and 8, a processing part 44 is provided in the slide 432, and the processing part 44 includes ten blowing holes 441 arranged at equal intervals on the inner wall of the slide 432, and the blowing holes 441 pass through the first protective plate 431, and the opening direction of the blowing holes 441 is toward the collaborative hand 2.
