Detailed Implementation

[0020] The following is based on the appendix Figure 1-3 Further explanation of this utility model:

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figure 1 and Figure 2As shown, the first embodiment of this utility model provides a millimeter-wave radar assembly laser marking device based on the prior art, including: a laser marking machine base 100, an operating table 101 on the top of the laser marking machine base 100, a product fixture assembly 800 and a lifting assembly 300 on the operating table 101, the execution end of the lifting assembly 300 being connected to the laser marking main beam 400, and a laser marking assembly 500 installed at the end of the laser marking main beam 400, the laser marking assembly 500 being arranged in a corresponding position to the product fixture assembly 800, the product fixture assembly 800, the lifting assembly 300, the laser marking main beam 400 and the laser marking assembly 500 being enclosed by a laser marking cover 200, an operation port 201 being provided on one side of the laser marking cover 200, and a conical shielding cover 600 being provided at the laser emitting lens port of the laser marking assembly 500. The operation port 201 is positioned corresponding to the conical shield 600. The execution end has the function of driving the laser marking main beam 400 to move up and down. The conical shield 600 has a marking position where its end cooperates with the product fixture assembly 800. The conical shield 600 also has an idle position where its end is separated from the product fixture assembly 800. The product fixture assembly 800 is used to limit the millimeter-wave radar assembly 700 to be marked.

[0025] In actual operation, the marking operation can be easily completed by simply placing the millimeter-wave radar assembly to be marked on the product fixture component. This design greatly improves the accuracy and efficiency of marking and effectively saves time costs.

[0026] The cone-shaped shield 600 has an aperture that gradually increases along a first preset direction. This gradual aperture design effectively reduces laser scattering, ensures the stability of the laser beam during propagation, and guarantees accurate marking positions for each application, avoiding deviations. For marking operations on components with extremely high precision requirements, such as millimeter-wave radar assemblies, this significantly improves the product yield. The larger aperture also expands the laser energy diffusion range to a certain extent, reducing the potential risks associated with energy concentration and lowering the radiation hazards to the surrounding environment and operators, creating a safer environment for marking operations.

[0027] like Figure 3 As shown, the product fixture assembly 800 includes: a product fixture base plate 803, which is mounted on the operating table 101; a product fixture support plate 804, which is mounted on the operating table 101 and its position corresponds to the conical shield 600; and a limiting component, which is mounted on the product fixture support plate 804 and is used to limit the millimeter-wave radar assembly 700 to be marked.

[0028] The limiting component includes: two vertical limiting blocks 805, which are symmetrically arranged near the upper and lower sides of the product fixture support plate 804; a first vertical limiting block 801, which is located at the top of the product fixture support plate 804 near one end and between the two vertical limiting blocks 805; and a second vertical limiting block 802, which is located at the top of the product fixture support plate 804 near the other end and between the two vertical limiting blocks 805. The two vertical limiting blocks 805 limit the vertical displacement of the millimeter-wave radar assembly 700 to be marked, while the first and second vertical limiting blocks 801 and 802 limit the horizontal displacement of the millimeter-wave radar assembly 700 to be marked. The cross-section of the vertical limiting blocks 805 is U-shaped or L-shaped.

[0029] Two vertical limiting blocks 805 are symmetrically positioned near the top and bottom edges of the product fixture support plate 804, effectively limiting the vertical displacement of the millimeter-wave radar assembly 700 to be marked, preventing the marking effect from being affected by vertical vibration during the marking process. Meanwhile, the first vertical limiting block 801 and the second vertical limiting block 802, located at both ends of the top of the product fixture support plate 804 and between the two vertical limiting blocks 805, precisely limit the horizontal displacement of the product. This multi-dimensional limiting method comprehensively ensures the stability of the millimeter-wave radar assembly during marking, allowing the laser to accurately act on the predetermined position, greatly improving marking accuracy and effectively reducing the defect rate.

[0030] Furthermore, a protective door 202 that can move along a second preset direction is provided inside the operating port 201. The protective door 202 has a working position that cooperates with the operating port 201, and a clearance position that is detached from the operating port 201. A display screen 203 is provided on the top of the operating port 201.

[0031] A protective door 202, movable along a second preset direction, is located inside the operating port 201. When in the working position, it closely cooperates with the operating port 201, forming an effective physical barrier. When the laser marking device is running, the protective door blocks potential laser scattering, preventing accidental injury to operators and greatly improving equipment safety while reducing potential safety hazards. The protective door 202 can be moved to a position away from the operating port 201, allowing operators to place or remove the millimeter-wave radar assembly to be marked without obstruction. This flexible design ensures both equipment safety during operation and ease of daily operation, enabling operators to efficiently complete loading and unloading tasks, saving operating time and improving overall work efficiency. A display screen 203 located at the top of the operating port 201 provides operators with an intuitive information display window. During the marking process, the display screen can show key information such as marking progress, equipment operating status, and parameter settings in real time. Operators can quickly obtain the information they need and understand the equipment's working status without the need for other equipment or complex operating interfaces. This allows them to make corresponding adjustments based on the actual situation, improving the convenience and efficiency of human-computer interaction and further optimizing the marking operation process.

[0032] Although embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and examples shown and described herein.
