Description

Technical Field

[0001] This utility model relates to the field of appearance inspection technology, specifically to an automotive radar vision inspection machine. Background Technology

[0002] With the continuous improvement of the intelligence and automation of automobiles, automotive radar, as a key sensor component, plays a vital role in the fields of active safety systems and autonomous driving assistance systems.

[0003] In the manufacturing process of automotive radar parts, visual inspection is a crucial line of defense for ensuring product quality, and its importance is self-evident. There is a type of automotive radar part that is generally in the shape of a rotating body. After the part completes its production process, a comprehensive and meticulous visual inspection is required on its top surface, the outer circumference of the top surface, and the transition arc surface connecting the two. The appearance quality of these parts directly affects the overall performance and service life of the part.

[0004] Currently, the visual inspection of this part mainly relies on manual methods. Specifically, inspectors visually inspect these areas for defects such as scratches, cracks, dents, burrs, and color differences, using tools such as magnifying glasses. However, this manual inspection method is extremely inefficient, requiring inspectors to meticulously observe and accurately judge each part individually, making the inspection of each part relatively time-consuming. In large-scale production, the number of parts to be inspected is enormous, requiring inspectors to maintain a high level of concentration for extended periods, easily leading to eye and physical fatigue, making the workload extremely heavy. This high-intensity work not only further reduces inspection efficiency but also seriously affects the accuracy of the inspection.

[0005] In view of the aforementioned problems with manual inspection methods, in order to improve the efficiency of appearance inspection of automotive radar parts, reduce labor intensity, meet the needs of large-scale production, and ensure the accuracy of inspection, it is necessary to develop an automotive radar vision inspection machine.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This invention provides an automotive radar visual inspection machine to solve the problem of how to improve the appearance inspection efficiency of rotating automotive radar parts and ensure the accuracy of the inspection.

[0020] See Figure 1 and Figure 2 As shown, Figure 1 This is a 3D view of the car radar vision inspection machine in the embodiment. Figure 2 for Figure 1 The enlarged schematic diagram at point A shows that the automotive radar vision inspection machine includes a frame 1, a conveyor line 2, a fixture 3, a top surface inspection device 4, and a peripheral surface inspection device 5.

[0021] The conveyor line 2 is mounted on the frame 1 by means of screwing or welding. The fixture 3 is located on the conveyor line 2. The fixture 3 is used for inserting and positioning the workpiece 12, ensuring that the top of the workpiece 12 faces upwards for inspection. The conveyor line 2 is used to transport the fixture 3.

[0022] Both the top surface inspection device 4 and the peripheral surface inspection device 5 are installed above the conveyor line 2 and arranged sequentially along the conveying direction of the conveyor line 2. The top surface inspection device 4 is used to inspect whether there are defects in the appearance of the top surface 121 of the workpiece 12. The peripheral surface inspection device 5 is used to inspect whether there are defects in the appearance of the top outer circumferential surface 122 of the workpiece 12 and the transition arc surface 123 connecting the top surface 121 and the top outer circumferential surface 122.

[0023] The automotive radar vision inspection machine described above, through the cooperation of conveyor line 2 and fixture 3, can stably and accurately transport rotating automotive radar parts sequentially to the designated inspection positions of top surface inspection device 4 and peripheral surface inspection device 5. Then, the top surface inspection device 4 and peripheral surface inspection device 5 can automatically perform comprehensive appearance inspection on three parts of the rotating automotive radar part: the top surface 121, the outer circumferential surface 122 of the top edge, and the transition arc surface 123 connecting the top surface 121 and the outer circumferential surface 122. Compared with traditional manual inspection methods, this invention automates the appearance inspection process, effectively improves the appearance inspection efficiency of rotating automotive radar parts, significantly reduces labor intensity, fully meets the needs of large-scale production, and ensures the accuracy of the inspection.

[0024] The aforementioned conveyor line 2 can use any one of the existing servo motor-belt conveyor mechanisms, shift fork conveyor mechanisms, or combinations of several of these conveyor mechanisms to achieve the conveying of the fixture 3.

[0025] See Figure 1 and Figure 2As shown, in one embodiment of the fixture 3, a plurality of slots 31 are evenly distributed on the fixture 3. The slots 31 are used for inserting a single workpiece 12 and for limiting the workpiece 12, ensuring that the top of the workpiece 12 faces upwards. The plurality of slots 31 form at least two inspection stations. The automotive radar vision inspection machine also includes a first drive device 6 and a second drive device 7 mounted on the frame 1. A top surface inspection device 4 is mounted on the output end of the first drive device 6. A peripheral surface inspection device 5 is mounted on the output end of the second drive device 7. The first drive device 6 drives the top surface inspection device 4 to sequentially face at least two inspection stations. The second drive device 7 drives the peripheral surface inspection device 5 to sequentially face at least two inspection stations. Thus, the fixture 3 can simultaneously accommodate several workpieces 12 through several slots 31. When the conveyor line 2 transports the fixture 3 to the designated inspection position of the top surface inspection device 4 or the peripheral surface inspection device 5, the top surface inspection device 4 can sequentially inspect several workpieces 12 at different inspection positions under the drive of the first drive device 6, while the peripheral surface inspection device 5 can sequentially inspect several workpieces 12 at different inspection positions under the drive of the second drive device 7. This realizes the automation and continuity of inspection, saves the time of conveying and positioning, and further improves the inspection efficiency.

[0026] The aforementioned single inspection station can cover only a single slot 31 (i.e., the inspection range of the inspection device covers only a single workpiece 12), or it can cover two or more slots 31 (i.e., the inspection range of the inspection device covers two or more workpieces 12). The former yields more accurate inspection results, while the latter offers higher inspection efficiency.

[0027] See Figure 1 and Figure 2As shown, in one embodiment of the circumferential surface inspection device 5, the device includes at least two circumferential surface inspection cameras 51 and prisms 52. The circumferential surface inspection cameras 51 are located above the conveyor line 2, and the at least two cameras 51 are arranged in a ring at equal intervals around a vertical line. The at least two cameras 51 are used in combination to inspect the appearance of the top outer circumferential surface 122 and the transition arc surface 123 of the workpiece 12 for defects. The number of prisms 52 is the same as the number of cameras 51, and they correspond one-to-one. The prisms 52 are located below the corresponding cameras 51. The cross-section of the prism 52 is an isosceles right triangle, and the two vertical faces of the prism 52 face the vertical line and the corresponding camera 51, respectively. The prisms 52 reflect the images of the top outer circumferential surface 122 and the transition arc surface 123 of the workpiece 12 to the corresponding camera 51. Thus, at least two circumferential inspection cameras 51 and at least two prisms 52 are arranged in a ring. During the inspection process, at least two prisms 52 can reflect the images of the outer circumferential surface 122 at the top of the workpiece 12 and the circumferential surface 123 of the transition arc surface from different angles to the corresponding circumferential inspection camera 51. This allows the combination of at least two circumferential inspection cameras 51 to fully capture the appearance of the entire outer circumferential surface 122 at the top of the workpiece 12 and the entire circumferential arc surface 123 of the transition arc surface, effectively avoiding blind spots in the inspection and further improving the comprehensiveness and accuracy of the inspection. It can be seen that the implementation method adopted by the peripheral surface inspection device 5 can effectively avoid the adverse effects on the inspection camera's detection of the outer peripheral surface caused by the mutual obstruction of the workpieces 12 when multiple workpieces 12 are simultaneously accommodated on the fixture 3, ensuring the smoothness of the inspection process and the reliability of the inspection results. Therefore, the peripheral surface inspection device 5 with this implementation method has wide applicability. It can be used not only to inspect the workpieces 12 on the fixture 3 that only accommodate a single workpiece 12, but also to inspect the workpieces 12 on the fixture 3 that simultaneously accommodate multiple workpieces 12.

[0028] The aforementioned peripheral inspection camera 51 can use existing visual inspection mechanisms such as CCD cameras, enabling it to quickly and accurately acquire appearance defects of the workpiece 12. The aforementioned prism 52 can be any existing prism 52. In this embodiment, there are three peripheral inspection cameras 51 and three prisms 52.

[0029] See Figure 2 and Figure 3 As shown, Figure 3This is a schematic diagram of the top surface detection device and the peripheral surface detection device in the embodiment. Based on the above embodiment, the peripheral surface detection device 5 further includes a first mounting frame 53 and a ring light source 54. The peripheral surface detection camera 51 and the ring light source 54 are both mounted on the first mounting frame 53 by screwing or welding. The lens of the peripheral surface detection camera 51 faces vertically downwards. The ring light source 54 is located between at least two prisms 52, and the axis of the ring light source 54 coincides with the vertical line. The ring light source 54 is used to illuminate the top of the workpiece 12 to be tested. The first mounting frame 53 has a receiving groove 531. The receiving groove 531 is used to place the prisms 52, exposing two vertical surfaces of the prisms 52, so that the two vertical surfaces of the prisms 52 face the corresponding peripheral surface detection camera 51 and ring light source 54 respectively. Thus, the design of the receiving slot 531 makes the assembly and disassembly of the prism 52 more convenient. Simply place the prism 52 into the receiving slot 531 to complete the installation and positioning of the prism 52. The ring light source 54 makes the image reflected by the prism 52 to the peripheral inspection camera 51 clearer, thereby further ensuring the accuracy of the inspection results of the peripheral inspection camera 51.

[0030] The aforementioned ring light source 54 can use existing ring-shaped LED lights.

[0031] See Figure 1 and Figure 3 As shown, in one embodiment of the top surface inspection device 4, the top surface inspection device 4 includes a top surface inspection camera 41. The top surface inspection camera 41 is located above the conveyor line 2 and is used to detect whether there are defects in the appearance of the top surface 121 of the workpiece 12. In this way, the top surface inspection device 4 can directly photograph and inspect the top surface 121 of the workpiece 12 through the top surface inspection camera 41, quickly and accurately discover the appearance defects in the top surface 121, and provide a reliable basis for evaluating the quality of the top surface 121 of the workpiece 12.

[0032] The aforementioned top surface inspection camera 41 can use existing visual inspection mechanisms such as CCD cameras, which can quickly and accurately collect appearance defects of the workpiece 12.

[0033] See Figure 1 and Figure 3As shown, based on the above embodiment, the top surface inspection device 4 further includes a second mounting bracket 42 and an illumination light source 43. The top surface inspection camera 41 and the illumination light source 43 are both mounted on the second mounting bracket 42 by means of screwing or welding. The top surface inspection camera 41 and the illumination light source 43 are located on opposite sides of the inspection station. The lens of the top surface inspection camera 41 and the illumination light from the illumination light source 43 are both tilted towards the inspection station. Thus, the illumination light source 43 tilts to illuminate the top surface 121 of the workpiece 12 on the inspection station, which, in conjunction with the tilted top surface inspection camera 41, makes the details of the top surface 121 more clearly visible, helping the top surface inspection camera 41 to more accurately capture the appearance defects of the top surface 121, further improving the accuracy of the inspection results of the top surface inspection device 4.

[0034] The aforementioned illumination light source 43 can be an existing LED lamp that can emit multiple parallel beams of light.

[0035] In a first embodiment of the first driving device 6 and the second driving device 7, at least two detection stations are arranged at equal intervals along a first direction. Both the first driving device 6 and the second driving device 7 include a first driving mechanism 61. The first driving mechanism 61 is mounted on the frame 1 by screwing or welding, and its output end is connected to the top surface detection device 4 or the peripheral surface detection device 5 by screwing or welding. The first driving mechanism 61 drives the top surface detection device 4 or the peripheral surface detection device 5 to move along the first direction, so that the top surface detection device 4 or the peripheral surface detection device 5 is sequentially positioned opposite the at least two detection stations. Thus, since the at least two detection stations are arranged at equal intervals along the first direction, the first driving device 6 and the second driving device 7 only need to drive the detection devices to move along the first direction via the first driving mechanism 61, enabling the detection devices to sequentially align with at least two detection stations and detect several workpieces 12 at different detection stations. This ensures the accuracy and stability of the detection, simplifies the driving structure, and reduces equipment costs.

[0036] See Figure 1 and Figure 3As shown, in a second embodiment of the first driving device 6 and the second driving device 7, at least two detection stations are arranged in an array along a first direction and a second direction. The first direction and the second direction are perpendicular to each other. Both the first driving device 6 and the second driving device 7 include a first driving mechanism 61 and a second driving mechanism 62. The first driving mechanism 61 is mounted on the frame 1 by means of screwing or welding. The second driving mechanism 62 is mounted on the output end of the first driving mechanism 61 by means of screwing or welding, and its output end is connected to the top surface detection device 4 or the peripheral surface detection device 5 by means of screwing or welding. The first driving mechanism 61 is used to drive the top surface detection device 4 or the peripheral surface detection device 5 to move along the first direction or the second direction. The second driving mechanism 62 is used to drive the top surface detection device 4 or the peripheral surface detection device 5 to move along the second direction or the first direction. Thus, since at least two inspection stations are arranged in an array along two mutually perpendicular directions, the first driving device 6 and the second driving device 7 cooperate through the first driving mechanism 61 and the second driving mechanism 62 to drive the inspection device to move freely in these two directions, flexibly inspecting several workpieces 12 at different inspection stations, thereby enhancing the adaptability and flexibility of the equipment.

[0037] Both the first drive mechanism 61 and the second drive mechanism 62 mentioned above can use existing linear displacement drive mechanisms such as servo motor-belt slider linear module or servo motor-screw nut linear module.

[0038] See Figure 1 and Figure 3 As shown, based on any of the above embodiments, the automotive radar vision inspection machine further includes a label feeding device 8, a third drive device 9, and a labeling device 10. The label feeding device 8 is mounted on the frame 1 by screwing or welding and is located on one side of the conveyor line 2. The label feeding device 8 is used to supply labels. The third drive device 9 is mounted on the frame 1 by screwing or welding. The labeling device 10 is mounted on the output end of the third drive device 9 by screwing or welding and is located above the conveyor line 2. The labeling device 10 is used to absorb or release labels. The third drive device 9 drives the labeling device 10 to reciprocate between the label feeding device 8 and the conveyor line 2 according to the detection results of the top surface detection device 4 and the peripheral surface detection device 5, so as to affix the labels supplied by the label feeding device 8 to the top surface 121 of the workpiece 12 that fails the inspection. Thus, the combination of the label feeding device 8, the third drive device 9, and the labeling device 10 realizes the automatic labeling function. This invention can automatically label unqualified workpieces 12 based on the test results to identify workpieces 12 with appearance defects, which facilitates subsequent sorting and processing, improves the efficiency and accuracy of production management, and reduces errors and labor intensity caused by manual operation.

[0039] The label feeding device 8 described above can use an existing label peeling device, which can automatically peel the label with the adhesive layer from the label tape, realizing automatic label feeding. The labeling device 10 described above can use an existing negative pressure suction nozzle, which can be connected to external vacuum adsorption equipment or other equipment to realize the adsorption and release of the label. The third driving device 9 described above can use an existing three-axis moving mechanism or a robotic arm or other automated equipment. In this embodiment, the third driving device 9 uses an existing three-axis moving mechanism, which can flexibly drive the labeling device 10 to move along the first direction, the second direction, and the vertical direction.

[0040] See Figure 1 As shown, based on any of the above embodiments, the automotive radar vision inspection machine further includes at least three clamping devices 11. The clamping devices 11 are mounted on the frame 1. The three clamping devices 11 are respectively positioned opposite to the top surface inspection device 4, the peripheral surface inspection device 5, and the labeling device 10. The clamping devices 11 are used to clamp or release the fixture 3 on the conveyor line 2. Thus, this invention, through the clamping devices 11, can clamp and fix the fixture 3 during the inspection and labeling process, preventing the fixture 3 and the workpiece 12 on it from moving or shaking, thereby further ensuring the accuracy and stability of inspection and labeling. Simultaneously, the clamping devices 11 can release the clamp on the fixture 3 when it is necessary to move it, facilitating the conveyor line 2 to transport the fixture 3, improving the overall operating efficiency and reliability of the equipment.

[0041] The clamping device 11 described above can use one or two existing telescopic cylinders in combination to clamp and release the fixture 3. In this embodiment, the clamping device 11 uses two telescopic cylinders, which are respectively screwed to both sides of the conveyor line 2. When the two telescopic cylinders extend simultaneously, they can clamp the fixture 3; conversely, they can release the fixture 3.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
