Description

Technical Field

[0001] The utility model relates to the technical field of laser marking machines, in particular to a material conveying mechanism suitable for laser marking machines. Background Art

[0002] Laser marking machines use laser beams to mark permanent marks on the surfaces of various materials. When large quantities of materials need to be marked, in order to improve marking efficiency, a conveying mechanism is needed to convey large quantities of materials so that each material passes through the marking area of ​​the laser marking machine for marking.

[0003] China Patent Network has published a material conveying device for a laser marking machine, with the publication number CN220347474U, which includes two connecting side panels and two hollow conveying mechanisms, which are symmetrically arranged at the two ends of the two connecting side panels. The utility model conveys the materials to be marked through the hollow conveying mechanism at the left end, and at the same time, a material taking and discharging mechanism at the left end sequentially moves the conveyed materials to the upper side of the middle support platform. After the laser marking machine completes marking the materials, a material taking and discharging mechanism at the right end moves the marked materials to the upper side of the hollow conveying mechanism at the right end. The whole process does not require the frequent starting and stopping of the motor used for conveying drive, which not only reduces the wear of the motor, but also reduces the additional energy consumption caused by frequent starting and stopping, thereby improving the energy saving of the device.

[0004] The above-mentioned device transmits the materials to be laser marked by a hollow conveying mechanism, but the materials need to be located directly under the laser marking machine before they can be marked. The above-mentioned device needs to manually position the materials when they are conveyed under the laser marking machine, which will increase the workload of the workers during the marking process. Therefore, a material conveying mechanism suitable for a laser marking machine is proposed. Utility Model Content
