it will be understood by those skilled in the art that the use of a magnet as the above-described marker is merely exemplary and that other marker materials, now known or later developed, that may be suitable for use in embodiments of the present invention are also encompassed within the scope of the present invention and are hereby incorporated by reference.

it will be appreciated by those skilled in the art that the number of scanning mechanisms shown in fig. 1 for simplicity only may be less than that in an actual network, but such omissions are clearly premised on a clear and complete disclosure of embodiments of the invention that will not be affected.

In summary, the embodiment of the invention provides a workpiece coating detection machine, which realizes full-automatic scanning, conveying and marking of workpiece coatings, standardizes the detection standards of coatings, improves the detection efficiency, greatly reduces the labor intensity and cost of manpower, and avoids manual misjudgment by adopting a split design and controlling a scanning mechanism, a conveying mechanism and a marking mechanism by a control system. Meanwhile, when the coating area of a workpiece to be detected is large, the multi-stage detection modules can be used for being assembled to cover the required detection area, so that the production and manufacturing cost of the detection equipment is reduced.

Those of ordinary skill in the art will understand that: the figures are merely schematic representations of one embodiment, and the blocks or flow diagrams in the figures are not necessarily required to practice the present invention.

from the above description of the embodiments, it is clear to those skilled in the art that the present invention can be implemented by software plus necessary general hardware platform. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which may be stored in a storage medium, such as ROM/RAM, magnetic disk, optical disk, etc., and includes instructions for causing a computer device (which may be a personal computer, a server, or a network device, etc.) to execute the method according to the embodiments or some parts of the embodiments.

the embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for apparatus or system embodiments, since they are substantially similar to method embodiments, they are described in relative terms, as long as they are described in partial descriptions of method embodiments. The above-described embodiments of the apparatus and system are merely illustrative, and the units described as separate parts may or may not be physically separate, and the parts displayed as units may or may not be physical units, may be located in one place, or may be distributed on a plurality of network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of the present embodiment. One of ordinary skill in the art can understand and implement it without inventive effort.

the above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
