Description

Technical Field

[0001] This utility model relates to the field of optical detection, and in particular to a camera tilt adjustment device. Background Technology

[0002] For some precision optical inspection equipment or machine vision devices that involve industrial cameras, due to issues with the precision of some optical path adjustments or the precision of optomechanical processing, the photosensitive surface of the camera and the optical image plane may not be parallel, and there may be an angle between them. As a result, for some systems with a small back depth of focus, the captured image may have some parts that are blurry and some parts that are sharp. No matter how the lens is refocused afterward, it is always impossible to keep all parts of the camera image equally sharp. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a camera tilt adjustment device to solve the above-mentioned problem.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A camera tilt adjustment device includes: an inner ring adjustment mechanism, two locking adjustment mechanisms, an outer ring adjustment mechanism, and a plurality of adjustment components. The two locking adjustment mechanisms are installed at intervals at one end of the outer ring adjustment mechanism. The outer ring adjustment mechanism is sleeved on one end of the inner ring adjustment mechanism. The inner ring adjustment mechanism is movably connected to the locking adjustment mechanism. The plurality of adjustment components pass through the outer ring adjustment mechanism at intervals and abut against the inner ring adjustment mechanism.

[0005] The beneficial effects of this utility model are as follows: multiple adjusting members pass through the outer ring adjusting mechanism at circumferential intervals and abut against the inner ring adjusting mechanism. This facilitates fine-tuning of the azimuth angle of the inner ring adjusting mechanism by adjusting the length of the adjusting members passing through the outer ring adjusting mechanism, thereby fine-tuning the camera angle mounted on the inner ring adjusting mechanism. This results in a higher parallelism between the camera's photosensitive surface and the optical image plane, improving image clarity. The inner ring adjusting mechanism and the locking adjusting mechanism are movably connected, which provides support when fine-tuning the azimuth angle of the inner ring adjusting mechanism. It also helps to lock and fix the azimuth angle of the inner ring adjusting mechanism after fine-tuning.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the inner ring adjustment mechanism includes an adjustment tube and a stop block. The stop block is fixedly sleeved on the adjustment tube and movably disposed between the two locking adjustment mechanisms. The outer ring adjustment mechanism is sleeved on one end of the adjustment tube.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the stop block is movably disposed between the two locking adjustment mechanisms, which is beneficial for providing support when fine-tuning the azimuth angle of the inner ring adjustment mechanism.

[0009] Furthermore, the adjusting tube includes an adjusting section and a camera connecting section connected in sequence, the stop block is fixedly sleeved on one end of the adjusting section near the camera connecting section, and the outer ring adjusting mechanism is sleeved on the adjusting section.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the outer ring adjustment mechanism is fitted on the adjustment section, which is conducive to fine-tuning the camera installed on the camera connection section by fine-tuning the orientation of the adjustment section.

[0011] Furthermore, the camera connecting section has threads on its circumferential outer wall, and the camera connecting section is used for threaded connection with the camera.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the camera connecting section is threadedly connected to the camera, which facilitates the disassembly and assembly of the camera, and also enhances the applicability of this device.

[0013] Furthermore, the outer ring adjustment mechanism is a tubular structure with an inner diameter smaller than the outer diameter of the stop block. The side wall of the outer ring adjustment mechanism is provided with multiple adjustment component through holes spaced circumferentially. The adjustment component through holes are threaded through holes, and the multiple adjustment components are threaded through the multiple adjustment component through holes one by one. The adjustment components abut against the outer wall of the adjustment section.

[0014] The advantages of adopting the above-mentioned further solution are: the inner diameter of the outer ring adjustment mechanism is smaller than the outer diameter of the stop block, which helps to prevent the stop block from falling into the inner ring adjustment mechanism; the thread of the adjustment component passes through the adjustment component through hole, which helps to adjust the length of the adjustment component entering the outer ring adjustment mechanism by thread, thereby fine-tuning the azimuth angle of the inner ring adjustment mechanism and the camera mounted on the inner ring adjustment mechanism.

[0015] Furthermore, the locking adjustment mechanism is an arc-shaped block structure, and the outer wall of the stop block is adapted to and connected to the inner wall of the locking adjustment mechanism.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the arc-shaped block structure of the locking adjustment mechanism is conducive to forming an adaptive connection with the stop block, and provides support for the inner ring adjustment mechanism by supporting the stop block during the fine adjustment process.

[0017] Furthermore, one of the locking adjustment mechanisms is fixedly installed at one end of the outer ring adjustment mechanism, and the other locking adjustment mechanism is detachably installed at one end of the outer ring adjustment mechanism.

[0018] The advantages of adopting the above-mentioned further scheme are: it facilitates the installation of the adjustment section into the outer ring adjustment mechanism and provides convenience for the stop block to be movably set between the two locking adjustment mechanisms.

[0019] Furthermore, the locking adjustment mechanism has two locking adjustment holes on its side wall, which are connected to the end of the locking adjustment mechanism. The two locking adjustment holes in the locking adjustment mechanism are connected by a threaded rod structure.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the locking adjustment holes in the two locking adjustment mechanisms are connected by a threaded rod structure, which is conducive to adjusting the tightness between the two locking adjustment mechanisms. Thus, after the azimuth angle of the camera is adjusted, the camera azimuth angle is fixed by locking the stop block through the two locking adjustment mechanisms.

[0021] Furthermore, the other end of the outer ring adjustment mechanism is a light path connection section, and the circumferential outer wall of the light path connection section is provided with threads, and the light path connection section is used to connect with the conversion cylinder by threads.

[0030] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0031] like Figure 1-3 As shown, this embodiment provides a camera tilt adjustment device, including: an inner ring adjustment mechanism 1, two locking adjustment mechanisms 2, an outer ring adjustment mechanism 3, and a plurality of adjustment components 4. The two locking adjustment mechanisms 2 are spaced apart and installed at one end of the outer ring adjustment mechanism 3. The outer ring adjustment mechanism 3 is sleeved on one end of the inner ring adjustment mechanism 1. The inner ring adjustment mechanism 1 is movably connected to the locking adjustment mechanism 2. The plurality of adjustment components 4 pass through the outer ring adjustment mechanism 3 circumferentially and abut against the inner ring adjustment mechanism 1.

[0032] The beneficial effects of this utility model are as follows: multiple adjusting members pass through the outer ring adjusting mechanism at circumferential intervals and abut against the inner ring adjusting mechanism. This facilitates fine-tuning of the azimuth angle of the inner ring adjusting mechanism by adjusting the length of the adjusting members passing through the outer ring adjusting mechanism, thereby fine-tuning the camera angle mounted on the inner ring adjusting mechanism. This results in a higher parallelism between the camera's photosensitive surface and the optical image plane, improving image clarity. The inner ring adjusting mechanism and the locking adjusting mechanism are movably connected, which provides support when fine-tuning the azimuth angle of the inner ring adjusting mechanism. It also helps to lock and fix the azimuth angle of the inner ring adjusting mechanism after fine-tuning.

[0033] Preferred, such as Figure 3 As shown, the inner ring adjustment mechanism 1 includes an adjustment tube 11 and a stop block 12. The stop block 12 is fixedly sleeved on the adjustment tube 11. The stop block 12 is movably disposed between the two locking adjustment mechanisms 2. The outer ring adjustment mechanism 3 is sleeved on one end of the adjustment tube 11.

[0034] The advantages of adopting the above preferred solution are: the stop block is movably disposed between the two locking adjustment mechanisms, which is beneficial for providing support when fine-tuning the azimuth angle of the inner ring adjustment mechanism.

[0035] Preferred, such as Figure 3 As shown, the regulating tube 11 includes an regulating section 111 and a camera connecting section 112 connected in sequence. The stop block 12 is fixedly sleeved on one end of the regulating section 111 near the camera connecting section 112, and the outer ring regulating mechanism 3 is sleeved on the regulating section 111.

[0036] It should be noted that in the technical solution of this utility model, when the outer ring adjustment mechanism 3 is sleeved on the adjustment section 111, the adjustment section 111 can swing freely within the outer ring adjustment mechanism 3, that is, the degree of freedom of the adjustment section 111 is not restricted within the outer ring adjustment mechanism 3. However, when the adjustment section 111 swings to abut against the inner wall of the outer ring adjustment mechanism 3, it will be restricted.

[0037] The advantages of adopting the above preferred scheme are: the outer ring adjustment mechanism is sleeved on the adjustment section, which is conducive to fine-tuning the camera installed on the camera connection section by fine-tuning the orientation of the adjustment section.

[0038] Preferred, such as Figure 1-3 As shown, the camera connecting section 112 has threads on its circumferential outer wall, and the camera connecting section 112 is used for threaded connection with the camera.

[0039] The advantages of adopting the above preferred solution are: the camera connecting section is threaded to the camera, which facilitates the disassembly and assembly of the camera and also enhances the applicability of the device.

[0040] Preferred, such as Figure 2-3 As shown, the outer ring adjustment mechanism 3 is a tubular structure with an inner diameter smaller than the outer diameter of the stop block 12. The side wall of the outer ring adjustment mechanism 3 is provided with a plurality of adjustment component through holes 32 spaced circumferentially. The adjustment component through holes 32 are threaded through holes. The plurality of adjustment components 4 are threaded through the plurality of adjustment component through holes 32 one by one. The adjustment component 4 abuts against the outer wall of the adjustment section 111.

[0041] The advantages of adopting the above preferred solution are: the inner diameter of the outer ring adjustment mechanism is smaller than the outer diameter of the stop block, which helps to prevent the stop block from falling into the outer ring adjustment mechanism; the thread of the adjustment component passes through the adjustment component through hole, which helps to adjust the length of the adjustment component entering the outer ring adjustment mechanism by thread, thereby fine-tuning the azimuth angle of the inner ring adjustment mechanism and the camera mounted on the inner ring adjustment mechanism.

[0042] Preferred, such as Figure 1 and Figure 3 As shown, the locking adjustment mechanism 2 is an arc-shaped block structure, and the outer wall of the stop block 12 is adapted to and connected to the inner wall of the locking adjustment mechanism 2.

[0043] It should be noted that in the technical solution of this utility model, "the stop block 12 is movably disposed between the two locking adjustment mechanisms 2" means that when the adjustment segment 111 is finely adjusted, the adjustment segment 111 will drive the stop block 12 to swing synchronously. At this time, the stop block 12 will move between the two locking adjustment mechanisms 2. However, no matter how the stop block 12 moves, the stop block 12 is supported by the two locking adjustment mechanisms 2.

[0044] The advantages of adopting the above preferred solution are: the locking adjustment mechanism with the arc-shaped block structure is conducive to forming an adaptive connection with the stop block, and provides support for the inner ring adjustment mechanism by supporting the stop block during the fine adjustment process.

[0045] Preferably, one of the locking adjustment mechanisms 2 is fixedly installed at one end of the outer ring adjustment mechanism 3, and the other locking adjustment mechanism 2 is detachably installed at one end of the outer ring adjustment mechanism 3.

[0046] The advantages of adopting the above preferred scheme are: it facilitates the installation of the adjustment section into the outer ring adjustment mechanism and provides convenience for the stop block to be movably set between the two locking adjustment mechanisms.

[0047] Preferred, such as Figure 1-3 As shown, the locking adjustment mechanism 2 has two locking adjustment holes 21 on its side wall. The locking adjustment holes 21 are connected to the ends of the locking adjustment mechanism 2, and the two locking adjustment holes 21 in the locking adjustment mechanism 2 are connected by a threaded rod structure.

[0048] It should be noted that in the technical solution of this utility model, the locking adjustment hole 21 is a threaded hole or a smooth hole;

[0049] In the technical solution of this utility model, such as Figure 1 As shown, since the locking adjustment mechanism 2 is an arc-shaped block structure, and the two locking adjustment mechanisms 2 are spaced apart, the ends of the two locking adjustment mechanisms 2 are arranged opposite each other. In addition, the locking adjustment hole 21 is connected to the end of the locking adjustment mechanism 2. Therefore, the locking adjustment holes 21 at the opposite ends of the two locking adjustment mechanisms 2 are threadedly connected by a threaded rod structure, so the tightness adjustment of the two locking adjustment mechanisms 2 can be realized.

[0050] The preferred structure for a threaded rod is a bolt-nut configuration.

[0051] The advantages of adopting the above preferred solution are: the locking adjustment holes in the two locking adjustment mechanisms are connected by a threaded rod structure, which is conducive to adjusting the tightness between the two locking adjustment mechanisms. Thus, after the azimuth angle of the camera is adjusted, the camera azimuth angle is fixed by locking the stop block through the two locking adjustment mechanisms.

[0052] Preferred, such as Figure 1-3 As shown, the other end of the outer ring adjustment mechanism 3 is a light path connection section 31. The outer circumferential wall of the light path connection section 31 is provided with threads, and the light path connection section 31 is used to connect with the conversion cylinder by threads.

[0053] It should be noted that in the technical solution of this utility model, the conversion cylinder has a structure with threads on the circumferential outer walls at both ends, and the outer diameters at both ends of the conversion cylinder are different. This is beneficial for adapting and connecting the optical path structure of the outer ring adjustment mechanism 3 and the device equipped with an industrial camera, which are of different sizes.

[0054] The advantages of adopting the above preferred solution are: the optical path connection section is threaded with the conversion cylinder, which is conducive to adapting to the optical path structure of devices with different sizes of outer ring adjustment mechanisms and industrial cameras, thus improving the applicability of the device.

[0055] Preferred, such as Figure 2 As shown, there are three adjusting components 4, which are bolts or screws.

[0056] It should be noted that in the technical solution of this utility model, the three adjusting members 4 are arranged at 120-degree intervals between each other.

[0057] The advantage of adopting the above preferred solution is that three bolts or screws help improve the stability when fine-tuning the camera's azimuth angle.

[0058] It should be noted that in the technical solution of this utility model, since both the adjusting tube 11 and the outer ring adjusting mechanism 3 are tubular structures, and the camera connecting section 112 in the adjusting tube 11 is connected to the camera, and the optical path connecting section 31 in the outer ring adjusting mechanism 3 is connected to the optical path structure of the device equipped with the industrial camera through a conversion tube, the inner surfaces of both the adjusting tube 11 and the outer ring adjusting mechanism 3 are anodized and blackened, which is beneficial to eliminating stray light.

[0059] The working process of this embodiment is described below:

[0060] First, connect the entire camera tilt adjustment device to the optical path structure in the existing device equipped with the industrial camera through the conversion tube, and then thread the industrial camera onto the camera connection section 112.

[0061] Then, thread the three adjusting parts 4 one by one through the three adjusting parts through holes 32, adjust the length of the three adjusting parts 4 inside the outer ring adjusting mechanism 3, so that the adjusting section 111 swings inside the outer ring adjusting mechanism 3. The swing of the adjusting section 111 will drive the stop block 12, the camera connecting section 112 and the industrial camera installed on the camera connecting section 112 to perform pitch adjustment, and finally achieve fine adjustment of the azimuth angle of the industrial camera.

[0062] Finally, when the overall image of the industrial camera can maintain the same clarity, the two locking adjustment mechanisms 2 are locked using bolts and nuts in the threaded rod structure, which means fixing the azimuth angle of the stop block 12, and finally fixing the azimuth angle of the fine-tuned industrial camera.

[0063] The advantages of this utility model are: fewer overall parts, simple and stable structure, continuously adjustable angle that can be firmly locked after adjustment, and the overall image of the camera can maintain the same clarity after debugging, avoiding the situation where some parts of an image are clear and some parts are blurry; in addition, without adding other mechanical structures to the existing device equipped with an industrial camera, the horizontal or vertical flip of the camera image can be physically adjusted by adjusting the rotation angle of the inner ring adjustment mechanism and the swing angle within the outer ring adjustment mechanism, without changing the distance of the camera relative to the light path.
