Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
[0034] As Figure 1 shown, the embodiment of the application provides a visual detection device, which includes a shell 100 and a reflection assembly 300. Wherein, the product 90 is within the range of the shell 100, the shell 100 is provided with at least a first image capture assembly 201 and a second image capture assembly 202, and the first image capture assembly 201 and the second image capture assembly 202 capture images of the product 90 at different angles, so that the visual detection device is adapted to various product shapes and various patterns.
[0035] Further, the reflection assembly 300 is inside the shell 100 and covers the outside of the product 90. The reflection assembly 300 can reflect light to the surface of the product 90, improve the brightness of the surface of the product 90, and make the image of the product 90 clearly displayed on the first image capture assembly 201 or the second image capture assembly 202. It can be understood that the clearer the captured product image is, the higher the accuracy of visual detection is.
[0036] In some examples, the shell 100 is formed as a box structure, and the bottom of the shell 100 is hollowed out. The product 90 is in the hollowed-out range of the bottom of the shell 100, facilitating the first image capture assembly 201 or the second image capture assembly 202 disposed on the shell 100 to obtain the image of the product 90.
[0037] The first image capture assembly 201 includes a camera module, and the second image capture assembly 202 includes a plurality of cameras, specifically two cameras.
[0038] In some examples, as shown in Figure 4 and Figure 5 The top wall of the shell 100 includes a horizontal part 1001 and an inclined part 1002 that are connected to each other, both of which are formed as a plate structure, and the horizontal part 1001 is at an angle with the inclined part 1002. The horizontal part 1001 forms a horizontal plane at the top of the shell 100, and the inclined part 1002 forms an inclined plane at the top of the shell 100.
[0039] Further, the horizontal part 1001 is in the middle of the shell 100, and the two inclined parts 1002 are on opposite sides of the horizontal part 1001 and are symmetrical about the horizontal part 1001. It can be understood that the top wall of the shell 100 can be bent from a whole plate.
[0040] The first image capture assembly 201 is installed on the horizontal part 1001, and when the product 90 is in the hollowed-out range of the bottom of the shell 100, the first image capture assembly 201 is facilitated to directly shoot the product 90 at the top of the product 90. The second image capture assembly 202 is installed on the inclined part 1002, and the second image capture assembly 202 is facilitated to obliquely shoot the product 90 at the top of the product 90, thereby providing different image capture angles for the product 90, so that the visual inspection device is adapted to various product shapes and various patterns.
[0041] In some examples, the light reflection assembly 300 is disposed inside the shell 100, and the light reflection assembly 300 at least includes a first light reflection component 301 and a second light reflection component 302.
[0042] The first light reflection component 301 and the second light reflection component 302 are independent components and can be used interchangeably. The first light reflection component 301 matches the first image capture assembly 201, and the second light reflection component 302 matches the second image capture assembly 202, that is, the light reflection component and the image capture assembly are one-to-one corresponding.
[0043] Further, the first light reflection component 301 and the second light reflection component 302 have the same basic shape and are both bent from a whole plate into an arc-shaped plate, facilitating the first light reflection component 301 and the second light reflection component 302 to be used interchangeably.
[0044] In some examples, a reflective component mounting structure is provided on the inner wall of the housing 100 near the bottom. Specifically, the reflective component mounting structure adopts a slot, and the width of the slot is set according to the thickness of the first reflective component 301 and the second reflective component 302, so that the first reflective component 301 or the second reflective component 302 can be inserted into the interior of the housing 100 through the slot, thereby realizing the detachable connection between the reflective component 300 and the housing 100.
[0045] The housing 100 has slots on both sides. The two sides of the first reflective component 301 or the second reflective component 302 are respectively inserted into the two slots, so that the first reflective component 301 or the second reflective component 302 covers the top of the product 90, so that the first reflective component 301 or the second reflective component 302 reflects light onto the surface of the product 90.
[0046] In some examples, such as Figure 2 As shown, the first reflective component 301 is provided with a first hollow portion 3011, which is formed as a hole structure on the first reflective component 301, and the position of the first hollow portion 3011 corresponds to the position of the first image capturing component 201, that is, it is located at the symmetrical center of the first reflective component 301.
[0047] When the first image capturing component 201 includes two cameras arranged side by side, the first cutout portion 3011 is a hole structure with two holes arranged side by side, and the lenses of the two cameras take pictures of the product 90 at the bottom of the first reflective component 301 through the first cutout portion 3011.
[0048] Simultaneously, the first reflective component 301 blocks the second image capturing component 202, preventing excessive perforations on the first reflective component 301 and ensuring that the product 90 receives sufficient light. Understandably, at this time, the second image capturing component 202 cannot acquire an image of the product 90.
[0049] In some examples, such as Figure 3 As shown, the second reflective component 302 is provided with a second hollow portion 3021, which is formed as a hole structure on the second reflective component 302, and the position of the second hollow portion 3021 corresponds to the position of the second image capturing component 202, that is, it is located at a position that is off-center from the symmetry center of the second reflective component 302.
[0050] When the second image capturing component 202 includes a single camera module, the second cutout portion 3021 is a single hole structure, and the lens of the camera module captures the product 90 at the bottom of the second reflective component 302 through the second cutout portion 3021.
[0051] Meanwhile, the second light-reflecting component 302 shields the first image capturing component 201, avoiding setting too many hole structures on the second light-reflecting component 302. At this time, the first image capturing component 201 cannot obtain the image of the product 90.
[0052] In some examples, as shown in FIG. 1, the shell 100 is provided with a light source assembly. The light emitted by the light source assembly is partially directly incident on the product 90, and the other part is incident on the product 90 through the light-reflecting assembly 300, thereby improving the surface brightness of the product 90. Figure 6
[0053] In some examples, the first light-reflecting component 301 and the second light-reflecting component 302 are both provided with a light inlet structure. Specifically, the light inlet structure adopts a light inlet hole. By physically adjusting the light inlet hole, the light inlet requirement under different cameras and different scenes can be met.
[0054] In some examples, the light source assembly includes an angle light source 401, a surface light source 402, a supplementary light source 403, and a line-scan linear light source.
[0055] In some examples, the angle light source 401 is rotatably arranged on the side wall of the shell 100. The angle light source 401 can adjust the angle, so as to adjust the brightness display according to the product pattern, so that the pattern is better fed back to the vision system.
[0056] The surface light source 402 is arranged at the position where the shell 100 is connected with the light-reflecting assembly 300. The surface light source 402 reflects the light to the surface of the product 90 through the light-reflecting assembly 300, which plays an auxiliary role in imaging of the vision camera. The supplementary light source 403 is arranged at the bottom of the shell 100 and plays a role of angle supplementary light.
[0057] In addition, the line-scan linear light source 404 is arranged inside the shell 100 and is used for lighting the circular or polygonal product 90.
[0058] In some examples, the shell 100 further includes a door structure. The door structure is arranged in the shell 100 in an openable and closable manner. When the door structure is opened, the first light-reflecting component 301 or the second light-reflecting component 302 is conveniently installed inside the shell 100. When the door structure is closed, the vision detection is conveniently performed.
[0059] In the actual implementation process, first, the first light-reflecting component 301 or the second light-reflecting component 302 is selected according to the shape and pattern of the product 90. Then, the existing light-reflecting component inside the shell 100 is taken out, and the selected first light-reflecting component 301 or second light-reflecting component 302 is inserted into the inside of the shell 100. When the product 90 reaches the bottom of the shell 100, the image capturing of the product 90 is performed by the image capturing component corresponding to the selected light-reflecting component, and the vision detection process is completed.
[0060] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
