Description

technical field [0001] The invention relates to the technical field of strip material engraving processing production equipment, in particular to a fully automatic strip laser cutting and engraving machine. Background technique [0002] The laser engraving machine can improve the engraving efficiency, make the surface of the engraved place smooth and round, rapidly reduce the temperature of the engraved non-metallic material, and reduce the deformation and internal stress of the engraved object; it can be widely used for various non-metallic materials Materials for finely carved areas. The advantage of laser processing is that it can quickly engrave and hollow out various patterns on the surface of various shoe upper materials. Since laser processing is a non-contact processing method, it will not cause any external deformation to the upper. It also has many advantages such as high engraving precision, hollow out without burr, and can process any shape. [0003] At present...

AI Technical Summary

Problems solved by technology

[0003] At present, laser engraving uses a focusing mirror to converge a laser beam with a diameter of about 6 mm to a focus point with a diameter of about 0.1 mm, and then uses the focus point to engrave the material. The laser head and working platform of a traditional engraving machine (honeycomb plate ) must be kept consistent. When processing strip-shaped materials, the material needs to be placed flat on the fixed position of the honeycomb panel to ensure the engraving accuracy. If the material is not flat, the focus will occur Larger changes, the material deviates from the focus point, the beam becomes thicker, and the penetrating power is poor, resulting in deformation of the engraving pattern or engraving not piercing through, which affects the engraving effect; then, the X-axis and Y-axis command the laser head to move, and the laser head moves on the strip material. Engraving or cutting out the pattern; after the engraving is completed, the machine is in standby mode, and the engraved products are manually put away, and then the waste carved on the honeycomb panel is cleaned. If the operation is repeated, if the engraving pattern is relatively simple, the standby time of the machine is often longer than the working time It is also long, which makes the machine unable to engrave and cut continuously for a long time, resulting in low production efficiency. In order to ensure a certain production efficiency, each double laser head engraving machine needs 1-2 workers to operate, which wastes manpower to a certain extent

[0004] In the production process, due to the high-density energy characteristics of the laser, when laser cutting upper materials, especially light-colored materials (such as white beige, etc.), or special materials (such as mirror materials, etc.), the bottom surface of the material is easy to appear The phenomenon of yellowing and blackening [During engraving, due to the high temperature during engraving, it is easy to generate smoke and dust. The bottom surface of the material placed flat on the honeycomb board and the place where the honeycomb board touches, the smoke cannot be dispersed in time, and it is affected by the smoke. It will cause the bottom surface of the material to turn yellow and black, which will affect the yield rate of the product]

In order to prevent this phenomenon, during production and processing, it is necessary to carry out certain protection treatment on the bottom surface of the material. The usual methods are: 1. Paste the protective film, it must be flat and tight, without air bubbles, and the processing is completed. Then remove the protective film, but this undoubtedly increases the processing difficulty and cost, the processing procedure becomes cumbersome, and increases the production time and production cost; 2. Apply cleaning agent to some shoe uppers, wash them off after carving, this method is applicable For some materials, the scope of implementation is relatively limited; 3. To adjust the laser processing parameters, the method of multiple times of small firepower is adopted, but the processing effect of the material is easily affected by the material displacement or processing error during the multiple processing process, which increases the Processing procedures, limiting production efficiency

[0005] In addition, in actual production, the existing engraving machine needs to drive the entire X-axis to move together when the Y-axis moves. The device makes the Y-axis move with a large load, causing the machine's take-off speed (the reaction speed of the engraving head to move from rest) and acceleration (the speed of the engraving head to move from the beginning to the speed set by the user) to lag behind. Due to the influence of its own weight, it is easy to shake during processing, resulting in jagged patterns on the engraved patterns, which affects the processing effect
