[0028] In order to further clarify the technical means and effects taken by the present application to achieve the predetermined purpose, the technical solutions in the embodiments of the present application are described clearly. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art belong to the scope of protection of the present application.

[0029] It should be noted that in this paper, the terms "include", "contain" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. Without more limitations, the element defined by the sentence "including a…" does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0030] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually a class, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0031] The description of the method flow in the specification and the steps of the flowchart in the drawings of the present application do not necessarily strictly follow the step number, and the method steps can change the execution order. Moreover, some steps can be omitted, multiple steps can be combined into one step for execution, and / or one step can be divided into multiple steps for execution.

[0032] The pneumatic marking and fixing device, apparatus, equipment and medium provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0033] First, the application scenarios of the pneumatic marking and fixing device in this application will be described in detail.

[0034] In actual laser marking processes, the marking fixture needs to be frequently disassembled from the product.

[0035] On the one hand, improper operation or operational errors are common sources of problems. Despite training, human factors such as fatigue and lack of concentration can still cause issues.

[0036] Disconcentration and other factors may still cause deviations in the assembly process, such as positioning products and starting the marking procedure, which in turn affects the marking effect and causes undesirable phenomena such as skewed markings and ghosting.

[0037] On the other hand, environmental factors cannot be ignored. In laser marking operations, the vibration generated by the worktable is enough to cause the product placed on the table to move slightly, ultimately causing the marking result to deviate from the intended position.

[0038] In some application scenarios, frequent disassembly is required due to the diversity of products.

[0039] Traditional fixing methods, such as using mechanical clamps or adhesives, can reduce product movement to some extent, but they have many limitations. For example, mechanical clamps may damage the product's paint surface due to excessive clamping force, or their complex structure may make quick installation and disassembly difficult; adhesives may leave residues that affect subsequent processing or the product's appearance.

[0040] Therefore, the difficulty in the marking process lies in determining the method for fixing the product, how to achieve rapid installation due to the diversity of products requiring frequent disassembly, how to control the clamping force, and how to fix the product without damaging the paint finish. This application proposes a pneumatic marking and fixing device, which can conveniently and effectively fix the product, reduce movement caused by improper operation or environmental factors during the marking process, and enable rapid installation and disassembly while protecting the product's appearance.
