Description

Technical Field

[0001] The invention belongs to the technical field of marking equipment, and in particular relates to a laser marking equipment. Background Art

[0002] Laser marking equipment uses laser beams to mark the surface of various materials permanently. The effect of marking is to expose the deep material through the evaporation of the surface material, thereby engraving exquisite patterns, trademarks and texts. Laser marking equipment is mainly divided into: CO2 laser marking equipment, semiconductor laser marking equipment, fiber laser marking equipment and YAG laser marking equipment. Laser marking equipment is mainly used in some occasions that require more precision and higher accuracy. It is used in electronic components, integrated circuits (ICs), electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, glasses and clocks, jewelry, auto parts, plastic buttons, building materials, and PVC pipes.

[0003] Traditional laser marking equipment is produced by manual loading / unloading. In order to save manpower, reduce production costs and improve the efficiency of loading / unloading, people use mechanical loading / unloading devices to replace manual labor to achieve automatic loading / unloading.

[0004] The mechanical loading / unloading device generally includes a loading rack for loading materials to be marked or marked materials, and a material transfer robot for transferring materials between the loading rack and the input / output end of the laser marking device. In the production implementation, enterprises generally use multiple laser marking devices to mark products and realize multi-station production to improve production capacity. However, under the existing equipment conditions, each laser marking device can only be adapted to the corresponding mechanical loading / unloading device to realize independent loading / unloading. In this way, multiple mechanical loading / unloading devices will increase the overall space occupied by the laser marking equipment and reduce the practicality of the laser marking equipment. At the same time, every three to four mechanical loading / unloading devices need to be equipped with operators to replenish / remove materials, and the manpower saving effect is general. Even if the purchase cost of the mechanical loading / unloading device is taken into account, the actual cost of the laser marking equipment with the mechanical loading / unloading device is higher than that of the laser marking equipment with pure manual loading / unloading, which is not conducive to the development of the enterprise.

[0069] Specifically, the working principle of the marking device 21 is as follows: the driving mechanism 216 drives the first limiting assembly 2152 and the second limiting assembly 2153 to overcome the driving force of the first elastic member 2154 and the second elastic member 2155 to move toward the outside of the clamping frame 2151, so that a cavity sufficient to accommodate the workpiece to be marked is formed on the inner side of the through groove 2156. When the loading device of the laser marking equipment conveys the workpiece to be marked into the through groove 2156, the driving mechanism 216 is reset, so that the first elastic member 2154 and the second elastic member 2155 respectively drive the first limiting assembly 2152 and the second limiting assembly 2153 to move toward the inner side of the through groove 2156, and the cavity becomes smaller to adapt to the workpiece to be marked, thereby achieving the clamping of the workpiece to be marked, and the lifting linear mechanism 213 drives The flip driving mechanism 214 moves upward to position the workpiece to be marked at a preset height to achieve focusing before marking.

The workpiece to be marked is moved into the through slot 2156 by the material transfer robot 41, and the pushing member drives the hook in reverse to reset the abutment block to achieve clamping.
