[0028] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] The following description, with reference to the accompanying drawings, describes a refrigeration device 1000 according to an embodiment of the present invention. Figures 1-5 As shown, the visual inspection component 100 according to an embodiment of the present invention includes a support 1 and a first image acquisition member 21. The first image acquisition member 21 is rotatably disposed on the support 1 so that the optical axis of the first image acquisition member 21 can form a predetermined angle with the center line of the object being inspected.

[0030] According to the present invention, the visual inspection component 100 rotatably mounts the first image acquisition member 21 on the bracket 1. When imaging the inspected object using the first image acquisition member 21, the first image acquisition member 21 is rotated so that the optical axis of the first image acquisition member 21 forms a predetermined angle with the center line of the inspected object, thereby enabling the simultaneous (one-time) accurate acquisition of multiple features of the inspected object.

[0031] Specifically, the multiple features of the inspected item include: at least two features opposite each other in a direction parallel to the centerline of the inspected item; and at least one feature located inside the aforementioned at least two features.

[0032] Related technologies first require a camera to acquire at least two of the aforementioned features from the outside of the object being inspected, and then require the camera to penetrate the interior of the object being inspected to acquire at least one of the aforementioned features. This application, by rotating the first image acquisition member 21 so that its optical axis forms a predetermined angle with the centerline of the object being inspected, can simultaneously and accurately acquire multiple features of the object being inspected, eliminating the need to penetrate the first image acquisition member 21 into the interior of the object being inspected to accurately acquire at least one of the aforementioned features.

[0033] Therefore, the visual inspection component 100 according to the present invention has the advantages of high inspection efficiency, fewer inspection steps, easy operation, and accurate inspection.

[0034] like Figures 1-5 As shown, the visual inspection assembly 100 includes a support 1, a first image acquisition member 21, and a first illumination member 31. The first image acquisition member 21 is rotatably mounted on the support 1 so that the optical axis of the first image acquisition member 21 can form a predetermined angle with the center line of the object being inspected.

[0035] The part being inspected can be a threaded insert (threaded sleeve, threaded insert, threaded insert). The threaded insert fits into a mounting hole (e.g., a blind hole). The annulus and thread of the threaded insert are opposite each other in a direction parallel to the center line of the threaded insert, and the shank of the threaded insert is located inside the annulus and thread and inside the mounting hole.

[0036] The relevant technology first uses a camera to capture the annular and threaded features of the threaded sleeve outside the mounting hole, and then uses the camera to penetrate into the mounting hole to capture the tail shank features of the threaded sleeve.

[0037] This application achieves simultaneous and accurate acquisition of the annular feature (feature 1), thread feature (feature 2), and shank feature (feature 3) of the threaded sleeve by rotating the first image acquisition member 21 to form a predetermined angle with the center line of the threaded sleeve. This eliminates the need for the first image acquisition member 21 to be inserted deep into the mounting hole to accurately acquire the shank feature, thus simplifying the inspection process, improving inspection efficiency, and facilitating inspection operations. Specifically, the presence or absence of the threaded sleeve is determined by features 1, 2, and 3, and the presence or absence of the shank is determined by feature 3.

[0038] Furthermore, since cameras in related technologies need to be inserted deep into the mounting hole, there are strict limitations on the size of the camera. The first image capturing component 21 of this application does not need to be inserted deep into the mounting hole, so the size, model, etc. of the first image capturing component 21 can be selected within a wider range, so as to effectively improve the performance of the first image capturing component 21 and reduce the cost of the first image capturing component 21.

[0039] Optionally, the predetermined included angle is greater than or equal to 4.6 degrees and less than or equal to 5.4 degrees. This allows for more accurate acquisition of the features of the inspected part (e.g., features 1, 2, and 3 of the threaded sleeve), thereby further improving the detection accuracy and precision of the vision inspection component 100 and effectively reducing the false alarm rate.

[0040] Further optionally, the predetermined included angle is greater than or equal to 4.7 degrees and less than or equal to 5.3 degrees. Further optionally, the predetermined included angle is greater than or equal to 4.9 degrees and less than or equal to 5.1 degrees. Further optionally, the predetermined included angle is equal to 5 degrees. This allows for more accurate acquisition of the features of the inspected object, thereby further improving the detection accuracy and precision of the visual inspection component 100 and effectively reducing the false alarm rate.

[0041] The first illumination element 31 and the first image capturing element 21 are linked so that they rotate synchronously. This allows the first illumination element 31 to better illuminate the object being inspected and to provide a better light source for the first image capturing element 21, enabling the first image capturing element 21 to more accurately acquire the features of the object being inspected. This further improves the detection accuracy and precision of the visual inspection component 100 and reduces the false alarm rate.

[0042] like Figures 2-4 As shown, the first illumination element 31 is arranged around the first image capturing element 21. This allows the first illumination element 31 to provide light to the object being inspected and the first image capturing element 21 more evenly, effectively reducing shadows. This enables the first image capturing element 21 to more accurately acquire the features of the object being inspected, thereby further improving the detection accuracy and precision of the visual inspection component 100 and further reducing the false alarm rate.

[0043] The first illumination element 31 may be annular to surround the first image capturing element 21. Furthermore, there may be multiple first illumination elements 31 arranged around the first image capturing element 21. The first illumination element 31 is connected to the first image capturing element 21 for better synchronization with its rotation.

[0044] like Figures 2-4As shown, the visual inspection assembly 100 also includes a first mounting member 4, which is rotatably mounted on the bracket 1. The first mounting member 4 includes a first mounting portion 41 and a second mounting portion 42, which are connected together. A first clamping cavity 43 is defined between the first mounting portion 41 and the second mounting portion 42, and the first image capturing member 21 is clamped in the first clamping cavity 43. This allows for more convenient and more secure mounting of the first image capturing member 21.

[0045] Optionally, the first mounting portion 41 is generally U-shaped, and both ends of the first mounting portion 41 are connected to the second mounting portion 42.

[0046] like Figures 1-4 As shown, the visual inspection assembly 100 also includes a first illumination mounting member 32. The first illumination mounting member 32 is disposed on the second mounting portion 42, and the first illumination element 31 is disposed on the first illumination mounting member 32. This allows for more convenient and more secure installation of the first illumination element 31. Furthermore, by disposing of both the first image capturing member 21 and the first illumination element 31 on the first mounting member 4, and by rotatably disposing the first mounting member 4 on the bracket 1, the first image capturing member 21 and the first illumination element 31 can rotate more accurately and synchronously.

[0047] Optionally, the second mounting portion 42 is perpendicular to the first mounting portion 41, and the first illumination element 31 and the first illumination mounting element 32 are parallel to the first mounting portion 41 (perpendicular to the second mounting portion 42). The optical axis of the first image capturing element 21 is perpendicular to the first mounting portion 41 (parallel to the second mounting portion 42). This allows the first illumination element 31 to be perpendicular to the optical axis of the first image capturing element 21, thereby enabling the first illumination element 31 to better provide light to the object being inspected and the first image capturing element 21.

[0048] like Figure 1 As shown, the visual inspection component 100 also includes a first protective cover 61, which covers the first image capturing member 21, that is, the first image capturing member 21 is disposed inside the first protective cover 61, so as to protect the first image capturing member 21 and prevent the first image capturing member 21 from being damaged.

[0049] Optionally, the first protective cover 61 is disposed within the first mounting member 4, that is, the first mounting member 4 is also disposed within the first protective cover 61, so as to facilitate the installation of the first protective cover 61. The first lighting mounting member 32 and the first lighting member 31 are located outside the first protective cover 61, so as to prevent the first protective cover 61 from blocking the light emitted by the first lighting member 31.

[0050] like Figures 2-4As shown, the bracket 1 includes a frame 11 and a second mounting member 12. The frame 11 includes a first mounting flange 111. The second mounting member 12 is rotatably disposed on the first mounting flange 111, and the first image capturing member 21 is disposed on the second mounting member 12. This allows the first image capturing member 21 to be rotatably disposed on the bracket 1 more conveniently.

[0051] One of the first mounting flange 111 and the second mounting member 12 is provided with a first arc groove 13. The vision inspection assembly 100 also includes a first locking member (not shown in the figure), which passes through the first arc groove 13 and also passes through the other of the first mounting flange 111 and the second mounting member 12. After the optical axis of the first image acquisition member 21 forms a predetermined angle with the center line of the object being inspected, the second mounting member 12 and the first image acquisition member 21 are locked to the first mounting flange 111 (frame 11) by the first locking member, so as to make the position of the first image acquisition member 21 more stable. This allows the first image acquisition member 21 to more accurately acquire the features of the object being inspected, thereby further improving the detection accuracy and precision of the vision inspection assembly 100 and further reducing the false alarm rate.

[0052] like Figures 1-4 As shown, the first mounting flange 111 is provided with a first arc groove 13, the center of which is located on the rotation axis of the second mounting member 12 (first image capturing member 21). The first locking member can be a bolt, which can be loosened before rotating the second mounting member 12 (first image capturing member 21). After the optical axis of the first image capturing member 21 forms a predetermined angle with the center line of the object being detected, the second mounting member 12 and the first image capturing member 21 are locked to the first mounting flange 111 (frame 11) by the bolt. Moreover, when rotating the second mounting member 12 (first image capturing member 21), the first arc groove 13 and the first locking member can also guide the second mounting member 12 (first image capturing member 21).

[0053] like Figures 2-4 As shown, the frame 11 includes two first mounting flanges 111, which are arranged opposite to each other and spaced apart in the extension direction of the rotation axis of the second mounting member 12 (first image capturing member 21). Each first mounting flange 111 is provided with a first arc groove 13.

[0054] The second mounting member 12 includes a plate 121, a first flange 122, and a second flange 123, both of which are disposed on the plate 121. The first flange 122 and the second flange 123 are arranged opposite to each other and spaced apart in the extension direction of the rotation axis of the second mounting member 12 (first image capturing member 21). The first flange 122 is rotatably disposed on one first mounting flange 111, and the second flange 123 is rotatably disposed on the other first mounting flange 111. The first image capturing member 21 is disposed on the plate 121.

[0055] There are two first locking elements. One first locking element passes through the first arc groove 13 of the first flange 122 and the first mounting flange 111, and the other first locking element passes through the first arc groove 13 of the second flange 123 and the other first mounting flange 111. This not only allows the first image capturing element 21 to be more securely mounted on the bracket 1, but also allows the first image capturing element 21 to rotate more stably, so as to more accurately control the angle between the optical axis of the first image capturing element 21 and the center line of the object being inspected, thereby enabling the first image capturing element 21 to more accurately acquire the features of the object being inspected.

[0056] Optionally, the second mounting portion 42 of the first mounting member 4 is connected to the second mounting member 12. For example, the second mounting portion 42 is connected to the plate 121 of the second mounting member 12 so that the first image capturing member 21 is disposed on the plate 121 (second mounting member 12) through the second mounting portion 42.

[0057] like Figure 2 , Figure 3 and Figure 5 As shown, the visual inspection component 100 also includes a second image acquisition element 22, which is disposed on the bracket 1. By providing the second image acquisition element 22, visual inspection of another type of inspected object can be performed using the second image acquisition element 22, thereby enabling the visual inspection component 100 to simultaneously perform visual inspection of two different types of inspected objects, thereby further improving the inspection efficiency and expanding the inspection range of the visual inspection component 100.

[0058] The first image acquisition device 21 and the second image acquisition device 22 can be cameras, video cameras, etc. The field of view of the second image acquisition device 22 is 450mm*300mm, and multiple objects can be detected within the field of view of one second image acquisition device 22.

[0059] Optionally, the second image acquisition member 22 is rotatably mounted on the support 1. Thus, when performing visual inspection of another type of inspected object using the second image acquisition member 22, the second image acquisition member 22 can be rotated to make it finely adjusted so that it faces the other type of inspected object.

[0060] Specifically, the second image acquisition unit 22 can inspect assembly standard parts (such as rivet nuts) to detect the presence or absence of assembly standard parts and whether they are qualified. For example, the vision inspection component 100 can be used for the visual inspection of integrated large die-cast parts, with the first image acquisition unit 21 inspecting threaded sleeves and the second image acquisition unit 22 inspecting rivet nuts.

[0061] like Figures 1-3 as well as Figure 5 As shown, the visual inspection component 100 also includes a second illumination element 33, which is arranged around the second image acquisition element 22. This allows the second illumination element 33 to provide light to the inspected object and the second image acquisition element 22 more uniformly, effectively reducing shadows. This enables the second image acquisition element 22 to more accurately acquire the features of the inspected object, further improving the detection accuracy and precision of the visual inspection component 100 and further reducing the false alarm rate.

[0062] The second illumination element 33 may be ring-shaped to surround the second image capturing element 22. Furthermore, there may be multiple second illumination elements 33 arranged around the second image capturing element 22.

[0063] Optionally, the second illumination element 33 and the second image acquisition element 22 are linked so that the second image acquisition element 22 and the second illumination element 33 rotate synchronously. This allows the second illumination element 33 to better illuminate the object being inspected and to better provide a light source for the second image acquisition element 22, enabling the second image acquisition element 22 to more accurately acquire the features of the object being inspected, thereby further improving the detection accuracy and precision of the visual inspection component 100 and further reducing the false alarm rate.

[0064] The first illumination element 31 is connected to the first image capturing element 21 so as to better rotate synchronously with the first image capturing element 21.

[0065] like Figure 2 , Figure 3 and Figure 5 As shown, the visual inspection assembly 100 also includes a third mounting member 5, which is rotatably mounted on the bracket 1. The third mounting member 5 includes a third mounting portion 51 and a fourth mounting portion 52, which are connected together. A second clamping cavity 53 is defined between the third mounting portion 51 and the fourth mounting portion 52, and the second image capturing member 22 is clamped in the second clamping cavity 53. This allows for more convenient and more secure mounting of the second image capturing member 22.

[0066] Optionally, the third mounting part 51 is generally U-shaped, and both ends of the third mounting part 51 are connected to the fourth mounting part 52.

[0067] like Figures 1-3 as well as Figure 5 As shown, the vision inspection assembly 100 also includes a second illumination mounting member 34. The second illumination mounting member 34 is disposed on the fourth mounting portion 52, and the second illumination element 33 is disposed on the second illumination mounting member 34. This allows for easier and more secure installation of the second illumination element 33. Furthermore, by disposing of both the second image capturing member 22 and the second illumination element 33 on the third mounting member 5, and by rotatably disposing the third mounting member 5 on the bracket 1, the second image capturing member 22 and the second illumination element 33 can rotate more accurately and synchronously.

[0068] Optionally, the fourth mounting portion 52 is perpendicular to the third mounting portion 51, and the second illumination element 33 and the second illumination mounting element 34 are parallel to the third mounting portion 51 (perpendicular to the fourth mounting portion 52). The optical axis of the second image capturing element 22 is perpendicular to the third mounting portion 51 (parallel to the fourth mounting portion 52). This allows the second illumination element 33 to be perpendicular to the optical axis of the second image capturing element 22, thereby enabling the second illumination element 33 to better provide light to the object being inspected and the second image capturing element 22.

[0069] like Figure 1 As shown, the visual inspection component 100 also includes a second protective cover 62, which covers the second image acquisition member 22, that is, the second image acquisition member 22 is disposed inside the second protective cover 62, so as to protect the second image acquisition member 22 and prevent the second image acquisition member 22 from being damaged.

[0070] Optionally, the second protective cover 62 is disposed within the third mounting member 5, i.e., the third mounting member 5 is also disposed within the second protective cover 62, so as to facilitate the installation of the second protective cover 62. The second lighting mounting member 34 and the second lighting member 33 are located outside the second protective cover 62, so as to prevent the second protective cover 62 from blocking the light emitted by the second lighting member 33.

[0071] like Figure 2 , Figure 3 and Figure 5 As shown, the bracket 1 includes a frame 11 and a fourth mounting member 14. The frame 11 includes a second mounting flange 112. The fourth mounting member 14 is rotatably mounted on the second mounting flange 112, and the second image capturing member 22 is mounted on the fourth mounting member 14. This allows the second image capturing member 22 to be rotatably mounted on the bracket 1 more conveniently.

[0072] One of the second mounting flange 112 and the fourth mounting member 14 is provided with a second arcuate groove 15. The vision inspection assembly 100 also includes a second locking member (not shown in the figure), which passes through the second arcuate groove 15 and also passes through the other of the second mounting flange 112 and the fourth mounting member 14. After the second image acquisition member 22 is finely adjusted to be aligned with the object to be inspected, the fourth mounting member 14 and the second image acquisition member 22 are locked to the second mounting flange 112 (frame 11) by the second locking member, so as to make the position of the second image acquisition member 22 more stable. This allows the second image acquisition member 22 to more accurately acquire the features of the object to be inspected, thereby further improving the detection accuracy and precision of the vision inspection assembly 100 and further reducing the false alarm rate.

[0073] like Figures 1-3 as well as Figure 5 As shown, the second mounting flange 112 is provided with a second arcuate groove 15, the center of which is located on the rotation axis of the fourth mounting member 14 (second image capturing member 22). The second locking member can be a bolt, which can be loosened before rotating the fourth mounting member 14 (second image capturing member 22). After the second image capturing member 22 is finely adjusted to be aligned with the object being inspected, the bolt is used to lock the fourth mounting member 14 and the second image capturing member 22 to the second mounting flange 112 (frame 11). Moreover, when rotating the fourth mounting member 14 (second image capturing member 22), the second arcuate groove 15 and the second locking member can also be used to guide the fourth mounting member 14 (second image capturing member 22).

[0074] like Figure 2 , Figure 3 and Figure 5 As shown, the frame 11 includes two second mounting flanges 112, which are arranged opposite to each other and spaced apart in the extension direction of the rotation axis of the fourth mounting member 14 (second image capturing member 22). Each second mounting flange 112 is provided with a second arc groove 15.

[0075] The fourth mounting component 14 includes a plate 141, a first flange 142, and a second flange 143, both of which are disposed on the plate 141. The first flange 142 and the second flange 143 are arranged opposite to each other and spaced apart in the extension direction of the rotation axis of the fourth mounting component 14 (second image capturing component 22). The first flange 142 is rotatably disposed on one second mounting flange 112, and the second flange 143 is rotatably disposed on the other second mounting flange 112. The second image capturing component 22 is disposed on the plate 141.

[0076] There are two second locking elements. One second locking element passes through the second arcuate groove 15 of the first flange 142 and the second mounting flange 112, and the other second locking element passes through the second arcuate groove 15 of the second flange 143 and the other second mounting flange 112. This not only allows the second image capturing element 22 to be more securely mounted on the bracket 1, but also allows the second image capturing element 22 to rotate more stably, so as to more accurately fine-tune the second image capturing element 22 to make it face the object being inspected, thereby enabling the second image capturing element 22 to more accurately acquire the features of the object being inspected.

[0077] Optionally, the fourth mounting portion 52 of the third mounting member 5 is connected to the fourth mounting member 14. For example, the fourth mounting portion 52 is connected to the plate 141 of the fourth mounting member 14 so that the second image capturing member 22 is disposed on the plate 141 (fourth mounting member 14) through the fourth mounting portion 52.

[0078] This utility model also discloses a visual inspection device 1000. For example... Figures 1-7 As shown, the visual inspection device 1000 includes a visual inspection component 100 and a base 200. The support 1 of the visual inspection component 100 is disposed on the base 200.

[0079] Accordingly, the visual inspection device 1000 according to the present invention has the advantages of high inspection efficiency, few inspection steps, easy operation, and accurate inspection.

[0080] Optionally, the visual inspection device 1000 further includes a drive unit disposed on the base 200. The drive unit is connected to the bracket 1 to drive the visual inspection assembly 100 to move, thereby driving the first image acquisition member 21 and the second image acquisition member 22 to move.

[0081] The relevant technologies all utilize fixed cameras (i.e., the cameras cannot move) for visual inspection and include two visual inspection methods. The first visual inspection method uses one or two cameras to capture all the characteristics of multiple inspected items, and then determines the inspection result. The first visual inspection method has low detection accuracy and a high false alarm rate.

[0082] The second visual inspection method uses cameras to inspect each part individually. This involves using multiple cameras to capture the features of multiple parts in a one-to-one correspondence. For example, multiple cameras might be inserted into multiple mounting holes to capture the tailstock features of multiple threaded ferrules. While this second visual inspection method offers higher accuracy, it is extremely costly.

[0083] This application uses a driving component to move the vision inspection assembly 100, thereby sequentially acquiring features of multiple inspected objects by moving the vision inspection assembly 100. This not only effectively improves the detection accuracy and precision of the vision inspection assembly 100 and the vision inspection device 1000, but also significantly reduces the manufacturing and inspection costs of the vision inspection device 1000.

[0084] like Figure 6 As shown, the driving component includes a robotic arm 300, which includes a joint 301. One end of the robotic arm 300 is disposed on the base 200, and the support 1 is disposed on the other end of the robotic arm 300. Thus, the robotic arm 300 can be used to drive the visual inspection component 100 to move, thereby improving the motion accuracy of the visual inspection component 100, and consequently improving the detection accuracy and precision of both the visual inspection component 100 and the visual inspection device 1000.

[0085] like Figure 6 As shown, there are multiple robotic arms 300 and multiple vision inspection components 100. One end of each robotic arm 300 is mounted on a base 200.
