[0036] like Figure 1 As shown, a millimeter-wave radar assembly and pressing device comprises: a frame 1, a workbench 2, and a pressing mechanism 3. The frame 1 has a pressing area 11. The workbench 2 is mounted on the frame 1 and located below the pressing area 11. The workbench 2 is provided with a fixture 4 for placing radar components. The pressing mechanism 3 is mounted on the frame 1 and located above the fixture 4. It should be noted that this embodiment includes a control device for controlling the activation of the pressing mechanism 3 to press the radar components in the fixture 4 together.

[0037] During actual use, the radar assembly is placed on the fixture base 4, and then the radar assembly is pressed together by the pressing mechanism 3. In this application, the fixture base 4 is used to place the radar assembly and define the position of the radar assembly. Then, the pressing mechanism 3 is used to press the assembly together to complete the assembly of the millimeter wave radar 5. The assembly and pressing equipment of this application can improve the assembly efficiency of the radar by cooperating with the pressing mechanism 3 and the fixture base 4, while avoiding damage to the radar assembly caused by manual operation and reducing production costs.

[0038] like Figure 3 and Figure 4As shown, in a specific example provided by this application, the fixture base 4 includes a base plate 41 and a fixture mounted on the base plate 41; the base plate 41 is connected to the workbench 2 via a connector 43; the fixture includes a placement seat 421, a support column 423 is provided between the bottom of the placement seat 421 and the base plate 41, and a placement groove 4211 is provided on the top of the placement seat 421 for placing the radar.

Specifically, in this embodiment, the first radar assembly is a housing 51, and the second radar assembly includes a PCB board 52 with a wiring harness 521 and a heat sink 53. During actual use, the housing 51 is first placed in the placement slot 4211, then the PCB board 52 with the wiring harness 521 is placed in the housing 51 and fixed, and finally the heat sink 53 is placed above the PCB board 52 with the wiring harness 521, and finally the heat sink 53 and the housing 51 are pressed together by the pressing mechanism 3. In this embodiment, the heat sink 53 and the housing 51 are a snap-fit structure, and the heat sink 53 and the housing 51 are snap-fitted together by the pressing mechanism 3. In this embodiment, the placement groove 4211 is used to place the shell 51 to ensure that the shell 51 can maintain a stable horizontal state. The guide groove 4221 on the guide column 422 is used to guide the placement of the PCB board 52 with the wiring harness 521 and the heat sink 53. Under the guidance of the guide groove 4221, the PCB board 52 and the heat sink 53 are kept falling vertically from top to bottom, thereby preventing the heat sink 53 from tilting and colliding with electronic components on the PCB board 52 during the falling process, avoiding damage to the radar assembly formed by the pressing of the first radar assembly and the second radar assembly, and improving the qualified rate of radar assembly.

[0039] like Figure 3 As shown, in a specific example provided in the present application, the clamp seat 4 further includes a harness clamp seat 44; the harness clamp seat 44 is mounted on the base plate 41 and is provided with a harness slot 441 for placing the harness 521. In this embodiment, the harness slot 441 on the harness clamp seat 44 is used to confine the harness 521 connected to the PCB board 52, so that the harness 521 can eliminate bending stress of the harness 521 under the constraint of the harness slot 441, thereby ensuring that the PCB board 52 remains in a stable state when placed horizontally during installation.

[0040] like Figure 2As shown, in a specific example provided in the present application, the connecting member 43 includes a connecting seat 431 and a limiting knob 432; a limiting hole 411 is provided on the substrate 41; the connecting seat 431 is fixed to the substrate around the limiting hole 411 by bolts 433, and the connecting seat 431 has a mounting hole 4311 corresponding to the limiting hole 411; the limiting knob 432 has a rotating shaft 4321 that passes through the mounting hole 4311 and the limiting hole 411, and partially passes through the substrate 41, and the lower half of the rotating shaft 4321 has a limiting rod 4322 that passes through the rotating shaft 4321.

[0041] like Figure 4 As shown in a specific example provided herein, a stopper protrusion 4323 is provided on the outer circumference of the upper half of the rotating shaft 4321; a 90° arc groove 4312 is provided on the connecting seat 431, which cooperates with the stopper protrusion 4323. Specifically, in this embodiment, the two sides of the 90° arc groove 4312 correspond to the two states of the stopper knob 432. During use, the stopper knob 432 can be quickly rotated to lock and unlock the position, improving installation efficiency and facilitating inspection and maintenance of the assembly and pressing equipment.

[0042] like Figure 4 and Figure 6 As shown, in a specific example provided by the present application, a connecting hole 22 is provided on the workbench 2; the connecting hole 22 includes a first hole 221 for the rotation shaft 4321 to pass through and a second hole 222 for the limit rod 4322 to pass through, and the first hole 221 is connected to the second hole 222.
