AI Technical Summary

Technical Problem

In existing multi-station laser marking machines, the limiting block cannot provide effective clamping force during the marking process, causing the parts to rotate slightly, which affects the clarity of the characters and the marking quality.

Method used

It adopts a rotating clamping structure, including components such as a center block, half clamping blocks, a rotating power device, a servo motor, and grippers. The rotating power device drives the half clamping blocks to clamp the parts, and the spring and gear system is used to achieve precise positioning and release of the parts. The cylinder and grippers are used to realize the transportation and positioning of the parts.

Benefits of technology

It achieves stable clamping of parts during the marking process, improves font clarity and marking quality, can adapt to the clamping requirements of parts of different sizes, and ensures accurate marking position.

Abstract

The utility model belongs to the field of laser marking, and discloses a multi-station automatic laser marking device, which comprises a cabinet, a rotating box, a laser generator, a conveying line, a finger cylinder, a left clamping jaw and a right clamping jaw which are arranged on the top surface of the cabinet, and a rotating clamping structure which is connected with the rotating box, the laser generator, the conveying line, the finger cylinder, the left clamping jaw and the right clamping jaw respectively arranged at the movable end of the finger cylinder. The rotating clamping structure is arranged above the rotating box, the bottom face of the rotating box is fixedly connected with the top face of the machine cabinet, one half clamping block resets and is matched with the other half clamping block to clamp the part, the two sides of the part obtain effective clamping force, the part is not prone to shaking when being marked through laser, the marking position is more accurate, and the production efficiency is improved. When the rotating plate rotates to the groove of the center block and is just located below the left clamping jaw and the right clamping jaw, due to the sunken groove, the spring located in the groove does not have extrusion force, the half clamping block is driven to be away from the other half clamping block actively, and the part loses clamping force.
