Manual Tool Changer for Robots

Manual Tool Changer for Robots

This technology is a manual tool changer mechanism for replacing robot end-effectors. When an operator moves the shaft using a handle, the shaft bracket, link, and hook bracket work in tandem to lock the guide pins of the lower mechanical plate.

Conventional technologies faced challenges such as manufacturing and setup difficulties due to complex structures, reduced coupling accuracy caused by bending deformation of the Z-axis reference plane, and the risk of tool detachment in air-driven systems if the air circuit fails.

This technology adopts a simplified mechanical linkage structure consisting of a shaft bracket, link, and hook bracket. It incorporates a PCB module for electrical signal connection and implements a mechanical locking device operated by a handle, ensuring robust tool coupling and safety during detachment. Applicable to industrial robots and automation systems, it enhances manufacturing process efficiency, maximizes installation space utilization, and optimizes robot utility in small-scale production.

Key Features:

• Upper mechanical plate featuring a component fixing groove with a guide hole on the bottom and a shaft bracket coupled to the shaft
• Fixing pin and link that slide through the elongated hole of the shaft bracket to rotate the link
• Lower mechanical plate including a cutout and guide pin that engage with the grooved hook bracket
• Structure where pushing the handle causes the shaft, link, and hook bracket to interlock, securely fastening the upper and lower plates
