Description

Technical Field

[0001] This utility model belongs to the technical field of transfer and feeding structure, specifically relating to a connection structure between a robotic arm and a feeding rack. Background Technology

[0002] When processing parts and assembling equipment, it is sometimes necessary to load and unload materials at multiple workstations. Due to the low level of automation in the production line, loading requires manual operation, resulting in low production efficiency. Currently, robotic arms are also used for loading, often three-axis robotic arms for picking and loading. However, the motors at the control rotation axes of the robotic arm need to be started and stopped, and the timing and interval of these starts and stops are difficult to control. Furthermore, the motors require time to transition from startup to low-energy operation. Therefore, it is crucial to develop a connection structure between the robotic arm and the loading rack that allows the motor to operate continuously while controlling the intermittent movement of the robotic arm.
