Description

[0002] During the production process, it is often necessary to inspect the appearance or interior of the product to ensure the quality of the finished product or component and to ensure a better yield rate. Due to the large size differences between different products, the corresponding inspection height will also change accordingly, but the traditional visual inspection mechanism has a fixed inspection angle and a limited inspection distance. When the product changes, the distance between the lens and the product changes, and the distance between the fill light and the product changes. Therefore, the distance between the product and the inspection camera may be too close or too far, resulting in unclear inspection images and affecting the inspection effect. If the visual inspection mechanism is replaced, it will take a long time to disassemble and assemble, and it will also be equipped with a variety of different visual inspection mechanisms, resulting in high production costs and low inspection efficiency.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0039] The utility model provides a visual inspection mechanism 100, which can be used to acquire images of inspection pieces, thereby judging whether the inspection pieces are qualified according to the acquired image information, and better ensuring the quality of the inspection pieces.

[0040] Specifically, see Figures 1 to 3 In this embodiment, the visual inspection mechanism 100 includes a base 1, a detection camera 2 and a fill light structure 3; the base 1 is suitable for the detection camera 2 and the fill light structure 3 to be installed thereon, and the base 1 can be connected with other mechanisms to connect the entire visual inspection mechanism 100 with other mechanisms; the detection camera 2 is movably arranged on the base 1 and has at least a movable stroke along the up and down directions of the base 1, and the detection camera 2 can be used to obtain image information of the detection piece; the fill light structure 3 is movably arranged on the base 1 and is located below the detection camera 2, the fill light center of the fill light structure 3 is coaxially arranged with the detection center of the detection camera 2, the fill light structure 3 has a movable stroke approaching and moving away from the detection camera 2, and the fill light structure 3 can be used to illuminate the detection piece with fill light, so that the detection camera 2 can obtain clearer image information.

[0041] In this embodiment, the detection camera 2 is movably arranged on the base 1 and has a movable stroke in the up-down direction of the base 1, so that the detection camera 2 can be fixed at different heights of the base 1, thereby better adapting to the detection requirements of products of different heights; moreover, the fill light structure 3 can also be movably arranged on the base 1 and can be moved in the up-down direction of the base 1, so that the relative distance between the fill light structure 3 and the product can be adjusted, so that the fill light structure 3 can better fill light for products of different heights, so that the visual inspection mechanism 100 can meet the inspection requirements of products of different sizes, and can ensure that after the product size changes, the detection camera 2 and the fill light structure 3 can be adjusted to an area that is better compatible with the product, so that the acquired product image information is clearer and more reliable, thereby improving the inspection effect.

[0042] The shape of the base 1 is not specifically limited. Figures 1 to 3 As shown, the base 1 includes a bottom plate 11, a side plate 12 and a support plate 13; the bottom plate 11 is arranged in a flat plate shape, and the side plate 12 stands on one side of the bottom plate 11 to be roughly perpendicular to the bottom plate 11; the support plate 13 is movably arranged on the side plate 12 along the up and down directions of the bottom plate 11, and the detection camera 2 and the fill light structure 3 are both connected to the support plate 13; the visual inspection mechanism 100 also includes a lifting drive structure 5, which is connected to the support plate 13 and is used to drive the support plate 13 to move along the up and down directions of the bottom plate 11, driving the detection camera 2 and the fill light structure 3 to move along the up and down directions of the bottom plate 11 together, thereby automatically adjusting the distance between the detection camera 2 and the fill light structure 3 and the detection component, so that the detection camera 2 can better obtain clearer image information.

[0043] It should be noted that, combined with Figure 1 As shown in , when the visual inspection mechanism 100 is used normally, the bottom plate 11 is arranged in the horizontal direction, the side plate 12 and the support plate 13 are both flat, and are both extended in the up-down direction, so that the detection camera 2 and the fill light structure 3 can move in the up-down direction driven by the support plate 13. Moreover, during normal inspection, the fill light structure 3 is located below the detection camera 2, and the detection component is located below the fill light structure 3, so that the detection component can be illuminated by the fill light structure 3, and the detection camera 2 can better obtain a clear image. The descriptions of the relevant directions in the utility model are all for reference in sequence.

[0044] Preferably, if Figure 3 As shown in , the lifting drive structure 5 includes a lifting drive motor 51, a lifting screw 52 connected to the lifting drive motor 51, a lifting nut screwed to the lifting screw 52, ​​and a transmission block 53 connected to the lifting nut. The lifting screw 52 is extended in the up-down direction. The support plate 13 is connected to the transmission block 53. The lifting drive motor 51 drives the lifting screw 52 to rotate, drives the lifting nut to move in the up-down direction along the lifting screw 52, ​​drives the transmission block 53 to move in the up-down direction, and drives the support plate 13 to move in the up-down direction along the transmission block 53, thereby realizing the movement of the detection camera 2 and the fill light structure 3 in the up-down direction. Among them, two guide rails are provided on the side plate 12, and two matching blocks are provided on the support plate 13. The two matching blocks are respectively slidably provided on the two guide rails in a one-to-one correspondence, so that the support plate 13 is more stable when moving in the up-down direction.

[0045] Moreover, combined with Figures 3 to 5As shown, the visual inspection mechanism 100 also includes two position detection structures 4, which are arranged at intervals along the up-down direction, and the two position detection structures 4 can respectively limit the upward movement stroke and the downward movement stroke of the support plate 13. Each position detection structure 4 includes a detector 41 arranged on the side plate 12, and a detection plate 42 arranged on the support plate 13. When the support plate 13 moves upward, and the detection plate 42 located at the top moves into the detection area of ​​the detector 41 located at the top, a first detection signal is triggered. At this time, the lifting drive motor 51 can be controlled to stop working to indicate that the support plate 13 moves upward to the highest position; similarly, when the support plate 13 moves upward, when the detection plate 42 located at the bottom moves into the detection area of ​​the detector 41 located at the bottom, a second detection information is triggered. At this time, the lifting drive motor 51 can be controlled to stop working to indicate that the support moves downward to the lowest position, so as to better control the displacement of the support plate 13.

[0046] Of course, the visual inspection mechanism 100 may also include a controller, which is electrically connected to the two position detection structures 4 and the lifting drive motor 51. The controller can control the operation of the lifting drive motor 51 through the detection information sent by the two position detection structures 4 to control the moving range of the support plate 13, thereby making the operation of the visual inspection mechanism 100 more intelligent.

[0047] It can be understood that when the movable range of the support plate 13 along the up and down directions of the base 1 is certain, when the lifting drive structure 5 drives the support plate 13 to move to the extreme position in the up and down directions, but still cannot meet the detection requirements of the detection parts, at this time, the position of the detection camera 2 and / or the fill light structure 3 relative to the support plate 13 can be adjusted, thereby changing the distance between the detection camera 2 and / or the fill light structure 3 and the detection part, so that the adjustment range of the detection camera 2 and the fill light structure 3 is larger and the scope of application is wider, which can meet the detection requirements of more detection parts.

[0048] Specifically, for the detection camera 2, combined with Figures 4 to 6 As shown, the detection camera 2 includes a camera body 21 and a lens structure 22 connected to the camera body 21 at one end, and the other end of the lens structure 22 is connected to the fill light structure 3. The camera body 21 can move along the up-down direction of the base 1, that is, the camera body 21 can move along the up-down direction relative to the support plate 13 to adjust the position of the camera body 21 on the support plate 13, and when the camera body 21 moves, the lens structure 22 can be driven to move relative to the fill light structure 3 to adjust the position of the lens structure 22 relative to the fill light structure 3. Among them, the camera body 21 includes an image sensor for acquiring image information, and the lens structure 22 includes a lens barrel and a plurality of lenses arranged in the lens barrel. The light at the detection member is transmitted through the plurality of lenses, so that the image sensor can acquire clearer image information.

[0049] Moreover, the camera body 21 further includes a camera housing 24, which is covered on the outside of the camera body 21 and the lens structure 22, and the lens structure 22 can pass through the bottom of the camera housing, and the camera body 21 and the lens structure 22 can be better protected by the camera housing 24. The height of the camera housing 24 in the vertical direction is substantially the same as that of the support plate 13, so that after the camera body 21 and the lens structure 22 move, the camera housing can still better protect the camera body 21 and the lens structure 22.

[0050] In addition, combined Figure 2 and Figure 4 As shown, the camera body 21 also includes a fan 25 arranged on the camera housing 24. Specifically, a through hole 111 is opened on the camera housing 24, and the through hole 111 is located on the side of the camera housing 24 facing away from the support plate 13. The fan 25 is arranged at the through hole 111, and the fan 25 is arranged corresponding to the camera body 21. The fan 25 can better discharge the heat generated at the camera body 21 to avoid the camera body 21 The temperature is too high and affects the image detection work.

[0051] It is understandable that there are many ways for the detection camera 2 to move relative to the support plate 13. In one embodiment, the detection camera 2 can be slidably arranged on the support plate 13, for example, a slide rail is provided on one of the detection camera 2 and the support plate 13, and a slider slidably matched with the slide rail is provided on the other, and the detection camera 2 can move up and down relative to the support plate 13 through the cooperation of the slide rail and the slider.

[0052] Preferably, a first mounting portion is provided on the support plate 13 of the base 1, and a first adjusting portion is provided on the camera body 21. The first mounting portion and the first adjusting portion cooperate with each other to fix the camera body 21 at different positions of the base 1 along the up and down directions to adjust the distance between the camera body 21 and the detection part.

[0053] In one embodiment, the first mounting portion and the first adjusting portion can be respectively configured as a first magnetic attraction portion and a plurality of second magnetic attraction portions, and the first magnetic attraction portion is magnetically attracted to different second magnetic attraction portions, thereby fixing the camera body 21 at different positions along the vertical direction of the support plate 13. Alternatively, the first mounting portion and the first adjusting portion are respectively a clamping protrusion and a clamping slot that are connected to each other, and by providing a plurality of clamping slots spaced apart in the vertical direction on the support plate 13, the clamping protrusion on the camera body 21 is clamped into different clamping slots, so as to fix the camera body 21 at different positions along the vertical direction of the support plate 13.

[0054] Preferably, combined Figure 5 and Figure 6As shown, the first mounting portion includes a plurality of first mounting holes 131 arranged at intervals along the vertical direction of the base 1, and the first adjustment portion includes a first long hole 211 provided on the camera body 21; the visual inspection mechanism 100 also includes a first connecting member, which is inserted into the first long hole 211 and different first mounting holes 131 to fix the camera body 21 at different positions along the vertical direction of the base 1. Among them, the first connecting member can be set as a pin, a bolt or a screw, etc., and the first connecting member is inserted into the first long hole 211 and the first mounting hole 131, so that the position of the camera body 21 can be easily adjusted, and the connection can be ensured to be more reliable, avoiding the phenomenon of loosening again during the inspection process, and it can also ensure that the inspection surface of the inspection camera 2 is directly opposite to the inspection member, and the stability is better.

[0055] For fill light structure 3, combined with Figure 5 and Figure 6 As shown, the fill light structure 3 includes a fill light frame 31 and a fill light 32 arranged on the fill light frame 31. The fill light frame 31 is connected to the support plate 13 of the base 1 and can move in the up and down direction relative to the support plate 13 of the base 1. The lens structure 22 is connected to the fill light frame 31. The fill light 32 and the detection camera 2 are independently fixed on the support plate 13, so that the fill light 32 and the detection camera 2 can move relatively, not only can the distance between the fill light 32 and the detection camera 2 and the detection part be adjusted, but also the distance between the fill light 32 and the detection camera 2 can be adjusted, so that the adjustment method is flexible and diverse, and can better meet the detection requirements of various detection parts.

[0056] It is understandable that the fill light frame 31 can move in a variety of ways relative to the support plate 13, similar to the way the camera body 21 moves relative to the support plate 13. Figure 5 and Figure 6 As shown in the figure, a plurality of second mounting holes 132 are provided on the support plate 13 of the base 1 and are spaced apart in the up-and-down direction of the bottom plate 11, and a second long hole 311 is provided on the fill light frame 31; the visual detection mechanism 100 also includes a second connecting member, which can be passed through the second long hole 311 and different second mounting holes 132 to fix the fill light frame 31 at different positions of the base 1 along the up-and-down direction, so as to adjust the distance between the fill light 32 and the detection member, and the distance between the fill light 32 and the lens structure 22 can be adjusted.

[0057] The more lenses there are in the lens structure 22, the longer the lens structure 22 is in the vertical direction. When the lens structure 22 is long, if the lens structure 22 has no fixed structure, the lens structure 22 is easy to shake. Especially for a device such as the lens structure 22 that has strict requirements for stability, when the lens structure 22 shakes slightly, the acquired image information will be blurred, thus affecting the detection effect. Figures 4 to 6As shown, the detection camera 2 also includes a lens support block 23 arranged on the fill light frame 31, and a clamping groove is provided on the lens support block 23, which is clamped on both sides of the lens structure 22, and the lens support block 23 has a movable stroke along the up and down direction of the base 1; when the camera body 21 moves along the up and down direction of the base 1, the lens support block 23 can also move relative to the fill light frame 31 along the up and down direction of the base 1. One end of the lens structure 22 is connected and fixed to the camera body 21, and the other end of the lens structure 22 is clamped and fixed by the lens support block 23, so that the connection of the lens structure 22 is more stable, ensuring that the image information obtained by the camera body 21 is clearer and more reliable. Moreover, connecting the lens support block 23 to the fill light frame 31 can ensure that the alignment of the lens structure 22 and the fill light 32 is more accurate, so that after the displacement, the lens structure 22 and the fill light 32 can always be coaxially arranged.

[0058] Preferably, a second mounting portion is provided on the fill light frame 31, and a second adjusting portion is provided on the lens support block 23. The second mounting portion and the second adjusting portion cooperate with each other to fix the lens support block 23 at different positions of the fill light frame 31 along the up and down directions, so that the position of the fill light frame 31 can be adjusted by the second mounting portion and the second adjusting portion. After the camera assembly moves relative to the support plate 13, the fill light frame 31 can move together with it; and when the length of the lens structure 22 itself changes, the lens support block 23 can also adjust its position, so that the supporting and fixing effect of the lens structure 22 is better.

[0059] Furthermore, if Figure 6 As shown in , the second mounting portion includes a plurality of third mounting holes 133 arranged at intervals along the vertical direction of the base 1, and the second adjustment portion includes a third long hole 231 provided on the lens support block 23; the visual inspection mechanism 100 also includes a third connecting member, which can be inserted into the third long hole 231 and different third mounting holes 133 to fix the lens support block 23 at different positions along the vertical direction of the fill light frame 31, so that the position of the lens support block 23 can be flexibly and conveniently adjusted. Among them, the third connecting member can be set as a pin, a bolt or a screw, etc., which is convenient and reliable to connect.

[0060] The visual inspection mechanism 100 provided by the utility model sets the camera body 21 and the fill-in light structure 3 to be movable, so that the camera body 21 and the fill-in light structure 3 can be better adapted to the inspection requirements of different inspection parts, and the distance between the camera body 21 and the fill-in light structure 3 can also be adjusted. When the lens structure 22 is replaced, the distance between the camera body 21 and the fill-in light structure 3 can be adjusted so that the fill-in light structure 3 can be adapted to the use requirements of different lens structures 22. Moreover, the lens support block 23 is also movably set, so that after the lens structure 22 changes, the lens support block 23 can be moved to different positions of the clamped fixed lens structure 22. Therefore, the visual inspection mechanism 100 provided by the utility model can inspect different inspection parts and ensure that the inspection information is reliable, and the adjustment is flexible and convenient, and the operation is simpler, so the inspection efficiency is higher, there is no need to replace the visual inspection mechanism 100 many times, and the inspection cost is also lower.
