Description

Technical Field

[0001] The utility model relates to the technical field of ratchet wrench assembly, in particular to ratchet wrench assembly equipment. Background Art

[0002] Ratchet wrenches are a locking tool that is often used in daily life. Ratchet wrenches are widely used in real life and involve many industries.

[0003] The main structure of a ratchet wrench is composed of a plate body and a plate head that can be movably connected, which makes it easy to adjust the angle. Therefore, before the ratchet wrench is assembled, it needs to go through the assembly of multiple parts. The assembly equipment usually includes a material feeding mechanism, a crimping mechanism, a fastener assembly mechanism, etc. These mechanisms work together to complete the assembly process of the ratchet wrench.

[0004] When assembling existing ratchet wrenches, a robotic arm is typically required to reciprocate and load the wrench. During this process, a single robotic arm must perform multiple reciprocating movements, which is time-consuming. Using multiple robotic arms improves work efficiency but increases production costs. Therefore, those skilled in the art have provided a ratchet wrench assembly device to address the issues raised in the background art. Utility Model Content
