They are often used to simplify complex assembly tasks, improve production efficiency, and ensure product quality. They can operate at various workstations to complete a variety of tasks. The advantages of collaborative robots can be summarized as three main points: safety, low cost, and ease of use. They are plug-and-play in most situations, making them an ideal fit for small and medium-sized enterprises.

[0003] The vast majority of existing collaborative robots are single-arm collaborative robots, which have low automation when loading and unloading materials, high labor intensity, limited movements, and cannot perform precise assembly work efficiently, resulting in a low scope of application. Utility Model Content

[0013] Compared with the existing technology, the present invention provides a collaborative robot multi-station detection and assembly mechanism with the following beneficial effects:

[0014] 1. The utility model sets a bidirectional motor and controls the bidirectional motor through a control panel to drive the two rotating shafts to rotate, and utilizes the cooperation between the rotating shaft and the connecting cylinder to drive the mechanical arm to rotate, which is convenient for adjusting the angle of the mechanical arm, and then adsorbs the material through the suction cup. A plurality of electric telescopic rods are set on the outside of the fixed plate, and the multiple electric telescopic rods adjust the position of the suction cup to achieve adsorption of materials of different sizes and specifications, increase the contact range, and increase the stability of loading and unloading. Then, it cooperates with the mechanical arm and the cylinder to facilitate the loading and unloading of materials, which can not only improve automation, but also reduce labor intensity.

[0015] 2. The utility model is provided with a camera and a tactile sensor. The camera can realize multi-angle detection through a rotating frame and a rotating mechanism, thereby increasing the monitoring range and occupying a small space, so that the collaborative robot has a wide range of applications. After the suction cup completes the adsorption of the material, the tactile sensor contacts the material, detects the material, and transmits the data to the control panel. If the tactile sensor fails to detect the material, it means that the adsorption at some positions is not completed, and the prompt light will flash to give a reminder and warning, which serves as a warning, improves the stability of loading and unloading, and prevents the material from falling during the process, causing damage and affecting the subsequent assembly work.
