It can be understood that when the number of the marking machines is multiple, the marking machine number also needs to be selected when the marking information is acquired.
For example, a product to be marked is an electronic device shell, positions needing marking are four corners of the product, four marking areas are marked on a target image according to the marking range of the marking machine, and XY axis driving information of the marking machine is automatically generated according to the four marking areas.
The material of product is the aluminum product, and material thickness is 0.4mm, and surface treatment is anodic treatment, and the marking mode is for getting rid of the surface oxidation layer, selects No. 1 marking machine, with the above-mentioned mark information input of beating in beating the mark model, the mark parameter of beating that obtains includes: the filling density is 0.04mm, the marking power is 60kHz, the marking speed is 5000mm/s, and the Q class is 80.

Step S505, comparing the second actual image with a preset standard image, and determining whether the second actual image is abnormal.
The height of the standard image at the marking position is equal to the height of the preset threshold, and if the height of the second actual image at the marking position exceeds the height of the standard image, it is judged that the second actual image has a convex hull at the marking position, namely the second actual image is abnormal.
When the second actual image is judged to be abnormal, the step S506 is carried out; if no abnormity exists, the process returns to step S501 to test the next marked product.

marking at least one marking region on the target image according to the target image and the marking range of the marking machine, and automatically generating XY-axis feeding information of the marking machine according to the marking region; and
and generating marking parameter information through a preset marking parameter model according to the characteristic information and the marking mode of the product, wherein the marking parameter information comprises at least one of filling density, marking power, marking speed, Q type, marking angle and marking times.
3. The marking control method as claimed in claim 2, wherein the characteristic information of the product to be marked at least includes material, material thickness and surface treatment of the product.
4. The marking control method as claimed in claim 2, wherein after marking the product, the method further comprises the steps of:
acquiring a first actual image of a marking surface of a product;
comparing the first actual image with the target image, and judging whether the first actual image is abnormal or not;
if so, generating first abnormal information, and adjusting the XY-axis feeding information according to the first abnormal information.
5. The marking control method according to claim 4, wherein the step of "adjusting the XY-axis feeding information according to the first abnormality information" is embodied as:
calculating first deviation data of the marking position in the first actual image;
calculating parameters of XY-axis feeding information to be compensated according to the first deviation data;
and adjusting the XY-axis feeding information according to the parameters of the XY-axis feeding information to be compensated.
6. The marking control method as claimed in claim 4, further comprising, after generating the first anomaly information, the steps of:
judging whether the first abnormal information continuously appears for a preset number of times;
if not, recording the first abnormal information;
if so, adjusting the XY-axis feeding information according to the first abnormal information.
7. The marking control method as claimed in claim 4, wherein when it is determined that the first actual image is not abnormal, the method further comprises:
acquiring a second actual image of the product deviating from the marking surface;
comparing the second actual image with a preset standard image, and judging whether the second actual image is abnormal or not;
if so, generating second abnormal information, and adjusting the marking parameter information according to the second abnormal information.
8. The marking control method according to claim 7, wherein the step of "adjusting the marking parameter information according to the second abnormality information" includes:
calculating second deviation data of a convex hull in the second actual image;
calculating marking parameters needing compensation according to the second deviation data;
and adjusting the marking parameter information according to the marking parameters to be compensated.
9. Marking control device comprising a processor and a memory, said memory having stored thereon a number of computer programs, characterized in that the processor is adapted to carry out the steps of the marking control method according to any one of claims 1 to 8 when executing the computer programs stored in the memory.
10. A computer-readable storage medium having stored thereon instructions executable by one or more processors to perform the steps of the marking control method as claimed in any one of claims 1 to 8.
