[0019] The following is based on the appendix Figure 1-4 Further explanation of this utility model:

[0020] 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.

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.

[0022] 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.

[0023] like Figure 1 and 2As shown, the first embodiment of this utility model provides a laser welding device for a millimeter-wave radar assembly based on the prior art, including: a welding frame base 100, a welding worktable 101 on the top of the welding frame base 100, a welding moving assembly 300 on the welding worktable 101, a laser welding device 500 on the execution end of the welding moving assembly 300, a laser welding positioning mechanism 400 on the welding worktable 101, the laser welding positioning mechanism 400 and the laser welding device 500 being positioned correspondingly, the welding moving assembly 300, the laser welding positioning mechanism 400 and the laser welding device 500 being enclosed by a welding frame cover 200, and an operation port 201 on one side of the welding frame cover 200; wherein, the operation port 201 is positioned correspondingly to the laser welding positioning mechanism 400, the laser welding positioning mechanism 400 is used to position the millimeter-wave radar assembly to be welded, and the laser welding device 500 has a working position for welding, or the laser welding device 500 has an idle position for standby.

[0024] The laser welding positioning mechanism 400 accurately positions the millimeter-wave radar assembly to be welded, ensuring the laser welding equipment 500 is accurately positioned during welding, thereby improving welding precision and ensuring consistent product quality. The welding moving assembly 300 can move the laser welding equipment 500, allowing it to switch between working and idle positions, facilitating use under different working conditions and improving the equipment's flexibility and applicability. The welding frame enclosure 200 encloses the welding moving assembly 300, the laser welding positioning mechanism 400, and the laser welding equipment 500, effectively preventing laser leakage and welding spatter from injuring operators and ensuring their safety. The operating port 201 corresponds to the laser welding positioning mechanism 400, facilitating the placement of the millimeter-wave radar assembly on the positioning mechanism and its removal after welding, making the operation more convenient and efficient. The enclosed design helps reduce the impact of noise and fumes generated during welding on the surrounding environment, improving the working environment and also facilitating equipment maintenance.

[0025] like Figure 3 As shown, the welding moving assembly 300 includes: a moving support 301, which is disposed on the top of the welding worktable 101; a linear driver 302, one end of which is vertically disposed on the moving support 301; and a welding moving beam 303, one end of which is connected to the execution end and the other end of which is connected to the laser welding equipment 500.

[0026] The welding moving assembly 300 also includes: a connecting frame 304, one end of which is connected to the other end of the welding moving beam 303; and an annular ring 305, one end of which is connected to the other end of the connecting frame 304, and the axis of the annular ring 305 is collinear with the axis of the laser output lens of the laser welding equipment 500.

[0027] The movable support 301 is mounted on top of the welding worktable 101, providing a stable mounting base for the entire welding moving assembly 300. The base of the linear actuator 302 is vertically mounted on the movable support 301. This vertical mounting method makes force transmission more direct and stable, ensuring the stability of the linear actuator 302 during operation, and thus ensuring the stability of the entire welding moving assembly 300, enabling reliable movement of the laser welding equipment 500. The presence of the linear actuator 302 allows the welding moving beam 303 to achieve precise linear motion. In the laser welding process of the millimeter-wave radar assembly, precise linear motion is crucial for controlling the position of the laser welding equipment 500, ensuring that the laser accurately acts on the area to be welded, improving welding accuracy and quality, and guaranteeing consistent welding results.

[0028] like Figure 4 As shown, the laser welding positioning mechanism 400 includes: a welding base plate 401, which is disposed on the welding worktable 101; a welding positioning boss 404, which is disposed on the welding base plate 401; and a limiting block 405, which is disposed on the welding positioning boss 404 and is used to limit the millimeter-wave radar assembly to be welded. The laser welding positioning mechanism 400 further includes: two drive cylinders 403, the bases of which are symmetrically arranged on the welding base plate 401, and a welding positioning boss 404 disposed between the two drive cylinders 403; at least two sliding rods 402, one end of which is vertically fixed to the welding base plate 401 on both sides of the welding positioning boss 404; and a limiting base 407, which is respectively sleeved on the at least two sliding rods 402, with both ends of the limiting base 407 connected to the execution ends of the two drive cylinders 403, and a through hole in the middle of the limiting base 407; wherein, the laser emitted by the laser welding equipment 500 passes through the through hole to weld the millimeter-wave radar assembly to be welded. The laser welding positioning mechanism 400 also includes: a light-transmitting plate 406 disposed at the through hole.

[0029] The welding base plate 401 is mounted on the welding worktable 101, providing a stable mounting platform for the entire positioning mechanism. This ensures that the positioning mechanism will not shake or shift during the welding process, thereby guaranteeing positioning accuracy and welding quality. The welding positioning boss 404 is mounted on the welding base plate 401, providing an accurate positioning reference for the millimeter-wave radar assembly to be welded. The limiting block 405 is mounted on the welding positioning boss 404, and the light-transmitting plate 406 is positioned at the through hole. This allows for precise positioning of the millimeter-wave radar assembly to be welded, maintaining its fixed position during welding and preventing welding defects due to positional deviations, thus improving welding accuracy and consistency. Two drive cylinders 403 are symmetrically mounted on the welding base plate 401, and the two ends of the limiting base 407 are connected to the actuators of the two drive cylinders 403 respectively. The extension and retraction of the drive cylinders 403 can move the limiting base 407 on the sliding rod 402, thereby achieving the limiting and adjustment of the millimeter-wave radar assembly to be welded.
