[0002] In automated production lines for radar products, the detection and sorting of appearance defects have long relied on manual visual inspection and manual unloading. This is not only inefficient and has a high rate of missed detections, but also labor-intensive and prone to secondary damage due to human factors. With the surge in millimeter-wave radar shipments, traditional single-station inspection equipment can no longer meet the cycle time requirements, and there is an urgent need for a high-efficiency tooling that integrates automatic feeding, dual-station alternating inspection, visual recognition, and sorting unloading. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model relates to a radar detection fixture. This fixture has a simple and reliable structure, effectively solves the aforementioned technical problems, and is suitable for widespread use. To achieve the above objectives, this utility model employs the following technical solution: A radar inspection fixture includes a base plate, a clamping and transfer mechanism, a visual inspection mechanism, and a feeding track. The base plate has a turntable with two symmetrically arranged positioning seats around its center. The positioning seats are used to hold the radar product to be inspected. The turntable drives the two positioning seats to rotate between a feeding station and an inspection station. The visual inspection mechanism includes a first linear cylinder, a support block, a slide table, a mounting table, an inspection camera, and first guide rods. The base plate has a through hole, and the two support seats are located below the base plate and on the front and rear sides of the through hole. The two first guide rods are symmetrically arranged. The slide is fixedly connected to two support seats at both ends. The slide has guide holes that slide with two guide rods. The cylinder body of the first linear cylinder is fixed below the slide. The piston rod of the first linear cylinder is connected to one of the support seats. The mounting platform is set above the slide and passes through the through hole. The detection camera is set on two trays of the mounting platform. The first linear cylinder is used to send the detection camera to the detection station to perform visual inspection of the radar product. The unloading track is fixedly connected to the base plate. The clamping and transfer mechanism is used to send the inspected radar product to the unloading track.

[0004] Based on the above scheme and as a preferred embodiment of the above scheme: the clamping and transfer mechanism includes a second linear cylinder, a support plate, a lifting cylinder, and a clamping cylinder. The second linear cylinder is fixed to the base plate by the support plate. The piston rod of the second linear cylinder faces forward and is connected to the lifting cylinder through a push block. The piston rod of the lifting cylinder faces downward and is connected to the lifting block. A clamping cylinder is provided below the lifting block. A clamping plate is connected to each end of the clamping cylinder. A support block is provided at the lower end of the clamping plate.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the clamping and transfer mechanism further includes a second guide rod and a slider. The two second guide rods are symmetrically arranged on both sides of the second linear cylinder. The slider is slidably connected to the second guide rods, and one side of the slider is connected to the lifting cylinder.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the feeding track is Y-shaped, and qualified product channels and unqualified product channels are formed on the lower two sides of the feeding track, respectively.

[0007] Based on the above scheme and as a preferred embodiment: the unloading track is equipped with an output switching mechanism, which is used to guide the sliding radar product into the qualified product channel or the unqualified product channel. The output switching mechanism includes a baffle, a third linear cylinder, and a lever. The baffle is set on the unloading track, and the bottom end of the hinge shaft of the baffle is connected to one end of the lever. The cylinder body of the third linear cylinder is rotatably engaged with the support rod at the bottom of the unloading track, and the piston rod of the third linear cylinder is rotatably connected to the other end of the lever. The third linear cylinder is used to drive the baffle to rotate through the lever.

[0008] The outstanding and beneficial technical effects of this invention compared to the prior art are as follows: By setting the detection camera as a sliding table structure that can move back and forth, it can standby outside the detection station and accurately take pictures inside the station, avoiding interference with the turntable. With the dual positioning seats working alternately, it can realize parallel operation of loading, detection and unloading, significantly improving the detection cycle. At the same time, combined with the Y-shaped unloading track and switching baffle, qualified products and unqualified products can be automatically separated after the detection is completed without manual intervention, realizing radar appearance detection with compact structure, high efficiency and accurate sorting.

Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0012] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0013] To solve the above technical problems, such as Figure 1-3 As shown, this utility model designs a radar inspection fixture, including a base plate 1, a clamping and transfer mechanism, an appearance inspection mechanism, and a feeding track 18. A turntable 2 is mounted on the base plate 1, and two positioning seats 3 are symmetrically arranged around the center of the turntable 2. The positioning seats 3 are used to place the radar product to be inspected. The turntable 2 is used to drive the two positioning seats 3 to switch between the feeding station and the inspection station. The appearance inspection mechanism includes a first linear cylinder 4, a support block 5, a slide table 6, a mounting platform 7, an inspection camera 8, and a first guide rod 9. The base plate 1 has a through hole. The two support seats are located below the base plate 1 and on the front and rear sides of the through hole. The two first guide rods 9 are symmetrically arranged left and right, and their ends are fixedly connected to the two support seats respectively. The slide table 6 has guide holes that slide with the two guide rods. The cylinder body of the first linear cylinder 4 is fixed to... Below the slide table 6, the piston rod of the first linear cylinder 4 is connected to one of the support seats. The mounting platform 7 is set above the slide table 6 and passes through the through hole. The detection camera 8 is set on the two trays of the mounting platform 7. The first linear cylinder 4 is used to send the detection camera 8 to the detection station to perform visual inspection of the radar product. The unloading track 18 is fixedly engaged with the base plate 1. The clamping and transfer mechanism is used to send the radar product that has been inspected to the unloading track 18. The first linear cylinder 4 pushes the slide table 6 to reciprocate along the guide rod below the base plate 1, so that the camera can stand by outside the detection station and accurately position itself to take pictures inside the station. This avoids the rotation path of the turntable 2 and ensures that the radar shell is completely and clearly imaged in one go. The dual positioning seats 3 alternately enter the loading, unloading and detection areas with the turntable 2, realizing parallel and continuous loading, visual inspection and unloading, and greatly improving the cycle time.

[0014] In this embodiment, it is further preferred that the clamping and transfer mechanism includes a second linear cylinder 10, a support plate 11, a lifting cylinder 12, and a clamping cylinder 13. The second linear cylinder 10 is fixed to the base plate 1 by the support plate 11. The piston rod of the second linear cylinder 10 faces forward and is connected to the lifting cylinder 12 through a push block. The piston rod of the lifting cylinder 12 faces downward and is connected to the lifting block. The clamping cylinder 13 is provided below the lifting block. A clamping plate 14 is connected to each end of the clamping cylinder 13. A support block 15 is provided at the lower end of the clamping plate 14. The piston rod is first pushed horizontally and then lifted vertically. Finally, the clamping plate 14 supports the block 15 to clamp the radar housing. No manual intervention is required throughout the process. The action is smooth and the positioning repeatability is high. The part can be picked up instantly after the turntable 2 rotates into place, which significantly shortens the material unloading waiting time.

[0015] In this embodiment, it is further preferred that the clamping and transfer mechanism also includes a second guide rod 16 and a slider 17. The two second guide rods 16 are symmetrically arranged on both sides of the second linear cylinder 10. The slider 17 is slidably connected to the second guide rods 16. One side of the slider 17 is connected to the lifting cylinder 12. The two second guide rods 16 and the slider 17 form a parallel guide pair, so that the lifting cylinder 12 maintains rigid support during horizontal movement, eliminates cantilever swaying, and ensures stable centering accuracy of the clamping plate 14. Even with high-speed start and stop, there will be no deviation, ensuring that the thin-walled radar housing is clamped smoothly without bumps or deformation.

[0016] In this embodiment, it is further preferred that the feeding track 18 is Y-shaped, and qualified product channels and unqualified product channels are formed on the lower two sides of the feeding track 18, respectively. Utilizing the gravity diversion principle of single-sided inlet and double-sided outlet, qualified products and unqualified products are guided to their respective channels by the switching baffle 19 at the top of the slide, realizing "one track, two separations" and eliminating the need for additional sorting stations.

[0017] In this embodiment, it is further preferred that the unloading track 18 is provided with an export switching mechanism. The export switching mechanism is used to guide the sliding radar product into a qualified product channel or a non-qualified product channel. The export switching mechanism includes a baffle 19, a third linear cylinder 20, and a lever 21. The baffle 19 is disposed on the unloading track 18, and the bottom end of the hinge shaft 22 of the baffle 19 is connected to one end of the lever 21. The cylinder body of the third linear cylinder 20 is rotatably engaged with the support rod at the bottom of the unloading track 18. The piston rod of cylinder 20 is rotatably connected to the other end of the lever 21. The third linear cylinder 20 is used to drive the baffle 19 to rotate through the lever 21. Utilizing the crank-rocker principle composed of the third linear cylinder 20, lever 21, and hinged baffle 19, the cylinder piston rod can drive the baffle 19 to quickly move within the Y-shaped slide by extending and retracting once, instantly changing the product's downward trajectory. The baffle 19 has precise cornering limits and fast switching response. It can be linked with the visual inspection results in real time to ensure that qualified and unqualified products enter their respective channels under the action of gravity.

[0018] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
