Description

Laser flight code printing method and device

Technical Field

The invention relates to the technical field of laser marking, in particular to a laser flight code printing method and device.

Background

Laser marking is a marking method in which a workpiece is irradiated locally with high-energy-density laser to vaporize a surface layer material or to undergo a chemical reaction of color change, thereby leaving a permanent mark. The laser marking can print various characters, symbols, patterns and the like, and the size of the characters can be from millimeter to micron, which has special significance for the anti-counterfeiting of products.

Along with the popularization of the application of laser marking equipment in the packaging and transportation industries, the demand for improving the efficiency is more and more extensive, and the production requirement cannot be met.

Disclosure of Invention

The invention aims to solve the problems and provide a laser flight code printing method and a laser flight code printing device which can greatly improve the working efficiency.

The object of the invention is achieved in the following way: a laser flight code printing method comprises the following steps:

A. products move forwards after being arranged in sequence on a conveying line, and a central server reasonably arranges the sequence of the products marked by the laser marking machine;

B. the N laser marking machines are marked as a first laser marking machine … … to an Nth laser marking machine according to different sequences;

C. when the product is detected by the product sensor, the central server processes the data and judges whether the laser marking machine has time to mark the product, and if the first laser marking machine has time, the product is arranged to the laser marking machine for marking;

D. if the first laser marking machine does not have time to mark the product, judging whether the laser marking machine has time to mark the product, and if the second laser marking machine has time, arranging the product to the second laser marking machine to mark; E. if the third laser marking machine does not have time to mark the product, judging whether the third laser marking machine has time to mark the product;

F. and in the same way, the central server controls the marking tasks distributed to the first laser marking machine to the Nth laser marking machine. The more optimized scheme is that in the double-sided laser marking device, the number of the laser marking machines in the step B is more than or equal to 2. The utility model provides a laser flight coding device, includes the transfer chain of non-intermittent continuous motion, the product of forward motion on the transfer chain, first laser marking machine, second laser marking machine, third laser marking machine and central server, the camera lens of first laser marking machine, second laser marking machine and third laser marking machine face directly to the product.

The more optimized scheme is that the laser flight code printing device further comprises at least one sensor arranged on one side of the conveying line, the sensor detects whether the conveying line has products or not, and the sensor transmits a received signal circuit to the central server.

The more optimized scheme is that the laser flight coding device is characterized in that the central server is used for controlling a corresponding idle laser marking machine to mark products on the conveying line.

The invention has the advantages that: the technical scheme of the invention reasonably solves the problem of the distribution of a plurality of laser marking machines to the product marking tasks on the same product conveying line, improves the working efficiency and reduces the cost.

2. The system can more reasonably arrange tasks for a plurality of lasers with different efficiencies and a laser control system, and has high automation degree.

3. Multiple sensors are no longer required, reducing costs and reducing the risk of failure due to sensor problems.

4. When one device fails, the reduced capacity can be shared by other devices, production is guaranteed, and corresponding risk judgment and reasonable avoidance are performed on the failure.

Drawings

In order that the present disclosure may be more readily and clearly understood, the present disclosure is now described in further detail with reference to the following detailed description taken in conjunction with the accompanying drawings, in which fig. 1 is a schematic structural view of the present disclosure;

the specific implementation mode is as follows:

as shown in fig. 1, a laser flight coding method is characterized by comprising the following steps:

B. the N laser marking machines are marked as a first laser marking machine … … to an Nth laser marking machine according to different sequences; and B, setting the number of the laser marking machines to be more than or equal to 2.

F. and in the same way, the central server controls the marking tasks distributed to the first laser marking machine to the Nth laser marking machine. The utility model provides a laser flight coding device, includes conveyor line 6 of continuous motion of non-intermittent type, the product 4 of forward motion on conveyor line 6, first laser marking machine 1, second laser marking machine 2, third laser marking machine 3 and central server 7, first laser marking machine 1, second laser marking machine 2 and the camera lens of third laser marking machine 3 face directly on product 4. The system also comprises at least one sensor 5 arranged on one side of the conveying line 6, wherein the sensor 5 is used for sensing whether the conveying line 6 has products or not, and the sensor 5 transmits a received signal circuit to the central server 7.

The central server 7 is used for controlling the products on the conveying line 6 to have corresponding idle laser marking machines for marking.

In the production process, the following corresponding relations exist, a first laser marking machine 1 marks a first product, a second laser marking machine 2 marks another product, a laser marking machine N marks an Nth product, and the marked products are adjacent or spaced by an integral multiple of N.

If the first laser marking machine 1 is efficient enough for marking products on the production line, all the products are marked by the laser marking machine 1, otherwise, the products are shared by the laser marking machine 2.

If the efficiency is not enough after the second laser marking machine 2 shares, the third laser marking machine 3 shares, and so on. The most efficient laser and control system is generally identified as the first laser marking machine 1, followed by the second laser marking machine 2, and so on.

The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
