Description

Technical Field

[0001] The utility model belongs to the technical field of machine vision cameras, and in particular relates to a machine vision camera installation structure with good flexibility. Background Art

[0002] A machine vision camera is a device used to capture and transmit images, mainly used in fields such as industrial automation and quality control. It usually consists of a lens, an image sensor, an image processor, and an output device. In a machine vision system, the role of a machine vision camera is to acquire an image of the target object and transmit it to the image processor for processing. The processed image can be used in a variety of applications, such as surface inspection, dimensional measurement, recognition, and tracking.

[0003] The machine vision camera needs to be installed before use. During installation, a mounting plate is provided on the machine vision camera, and the camera is installed through the mounting plate.

[0004] In the prior art, bolts are generally used for fixing. When fixing, the bolts enter the mounting holes on the mounting plate and are installed on the mounting plate. However, during installation, accessories such as screws and nuts need to be prepared, and a screwdriver or power tool needs to be used for installation. The installation process is relatively cumbersome. Once the screws are fixed in place, it takes a long time to remove them, which is time-consuming and laborious.

[0005] At the same time, there is also a method of fixing by clamping in the prior art. This fixing method generally uses a spring or a threaded rod to clamp the clamping plate to the machine vision camera body. However, this clamping force is mostly generated by friction. If the friction is insufficient or the machine vision camera body vibrates, the friction will become weak, resulting in a poor fixing effect.

[0006] To this end, we have proposed a flexible machine vision camera installation structure, which is not only convenient for installation and disassembly, thus saving time and effort, but also has a stable fixing effect and is adaptable to different machine vision cameras. Utility Model Content

[0029] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0030] like Figure 1-8As shown, the technical solution adopted by the present invention is as follows: a machine vision camera installation structure with good flexibility, including a machine vision camera body 1 and a hollow installation shell 2 for installing the machine vision camera;

[0031] A mounting plate 3 is provided on the machine vision camera body 1, and a first arc-shaped groove 4 is formed on the mounting plate 3;

[0032] A mounting groove 5 is provided on the hollow mounting shell 2, and a second arc groove 6 and a third arc groove 7 which are connected to the inner wall of the hollow cavity of the hollow mounting shell 2 are provided on the inner wall of the mounting groove 5. A rotating assembly is provided inside the hollow mounting shell 2, and a semicircular fixing plate 8 is provided on the rotating assembly. The semicircular fixing plate 8 is driven by the rotating assembly to rotate and fix in the first arc groove 4, the second arc groove 6 and the third arc groove 7.

[0033] Its working principle is: first, the mounting plate 3 drives the machine vision camera body 1 to enter the mounting groove 5. At this time, a circular channel can be formed between the first arc groove 4, the second arc groove 6 and the third arc groove 7. At this time, the semicircular fixing plate 8 is driven by the rotating component to enter the circular channel formed by the first arc groove 4, the second arc groove 6 and the third arc groove 7 to rotate. During the rotation, the mounting plate 3 is connected to the hollow mounting shell 2 to complete the installation.

[0034] Compared with the prior art: In the prior art, bolts are generally used for fixing. When fixing, the bolts enter the mounting holes on the mounting plate 3 and are installed on the mounting plate 3. However, during installation, screws, nuts and other accessories need to be prepared, and a screwdriver or power tool needs to be used for installation. The installation process is relatively cumbersome. Once the screws are fixed in place, disassembly takes a long time, which is time-consuming and laborious.

[0035] At the same time, there is also a method of fixing by clamping in the prior art. This fixing method generally uses a spring 16 or a threaded rod to clamp the clamping plate to the machine vision camera body 1, but the clamping force is mostly generated by friction. If the friction is not enough or the machine vision camera body 1 vibrates, the friction will become weak, resulting in a poor fixing effect.

[0036] The utility model has the advantages:

[0037] 1. High stability: The structure adopts the design of a hollow mounting shell 2 and a semicircular fixing plate 8, which can effectively fix the camera at a desired position, prevent the camera from shaking or shifting, and ensure the stability of shooting.

[0038] 2. Wide applicability: Because the structure has the advantages of high flexibility, quick installation and disassembly, and high stability, it can be widely used in security monitoring, etc.

[0039] 3. Easy to customize and adjust: The various components of the structure (such as the mounting plate 3, the arc groove, the hollow mounting shell 2, etc.) can be customized and adjusted according to actual needs to meet the needs of different users and scenarios. This provides users with greater flexibility and allows customized design and adjustment according to specific circumstances.

[0040] 4. Easy maintenance and upgrade: The design of the structure makes maintenance and upgrade relatively easy. If the camera needs to be replaced or upgraded, the user can easily dismantle the existing mounting structure and then adjust or replace it as needed without making large-scale changes or replacements to the entire system.

[0041] 5. Reduce costs: Due to the simple design and high flexibility of the structure, the production and manufacturing costs can be reduced. At the same time, due to its easy maintenance and upgrade characteristics, the use cost and operating cost are also reduced.

[0042] like Figure 8 As shown, the semicircular fixing plate 8 is composed of a first arc plate, a second arc plate and a third arc plate. The first arc plate and the third arc plate are both provided with an arc groove, and a second arc plate is arranged inside the arc groove. The second arc plate is fixed inside the arc groove by bolts. Such an arrangement can adjust the diameter of the entire semicircular fixing plate 8. By sliding the second arc plate on the first arc plate and the second arc plate, the diameter of the circle can be adjusted, and the size of the semicircular fixing plate 8 can be adjusted, so as to adapt to the fixation of different machine vision camera bodies 1.

[0043] The mounting plate 3 matches the mounting groove 5. Matching here means that the mounting plate 3 can enter the mounting groove 5 without shaking, thereby improving the installation effect.

[0044] At the same time, an anti-skid surface is provided on the inner wall of the installation groove 5, and the anti-skid surface can achieve an effect of preventing sliding.

[0045] like Figure 3 As shown, the center point of the first arc groove 4, the center point of the second arc groove 6, the center point of the third arc groove 7 and the center point of the semicircular fixing plate 8 are all the same. The advantage of this arrangement is that the semicircular fixing plate 8 can be fixed by the first arc groove 4, the second arc groove 6 and the third arc groove 7 when rotating.

[0046] like Figure 6As shown, the rotating assembly includes a first supporting plate 9 connected to a semicircular fixing plate 8, a first rotating shaft 10 is arranged at the bottom of the first supporting plate 9, one end of the first rotating shaft 10 passes through the hollow mounting shell 2 and is installed with a rotating disk 13, the other end of the first rotating shaft 10 passes through the hollow mounting shell 2 and is installed with a rotating seat, the first rotating shaft 10 is driven to rotate by the rotating disk 13, and the first rotating shaft 10 drives the semicircular fixing plate 8 to rotate, thereby being fixed by the first arc groove 4, the second arc groove 6 and the third arc groove 7.

[0047] It should be noted that: the first support plate 9 is connected to one end of the semicircular fixing plate 8. When it is limited to be connected to one end of the semicircular fixing plate 8, its rotation direction is to rotate toward the direction of the unfixed position of the other end of the semicircular fixing plate 8. In this way, when rotating, the first support plate 9 will rotate inside the hollow mounting shell 2, thereby not causing interference.

[0048] like Figure 4 As shown, in order to ensure locking when fixing, a first fixing hole is opened on the rotating disk 13, a movable rod 14 is arranged inside the first fixing hole, a fixed disk 15 is arranged at the bottom of the movable rod 14, a limit disk is arranged on the top of the movable rod 14, and a spring 16 is sleeved on the movable rod 14, and the spring 16 is located between the fixed disk 15 and the rotating disk 13, and a plurality of second fixing holes 17 are arranged in an array on the hollow mounting shell 2, and the fixed disk 15 is inserted into the second fixing hole 17.

[0049] When the semicircular fixing plate 8 is fixed, the fixing plate 15 enters the second fixing hole 17 and is locked by the elastic force of the spring 16, thereby improving the fixing effect.

[0050] First, the lock is released when in use, and the limit plate is pulled, which drives the movable rod 14 to pull the fixed plate 15 out of the second fixed hole 17 and squeeze the spring 16, so that the rotating plate 13 can rotate.

[0051] The fixing plate 15 matches the second fixing hole 17 , so that the fixing plate 15 can enter the second fixing hole 17 , and the clearance fit will not cause shaking.

[0052] like Figure 1 As shown, in order to achieve a good flexibility effect, a first support plate 9 is arranged on the top of the hollow mounting shell 2, a second connecting plate 19 is hinged on the top of the first connecting plate 18, and the hinge of the first connecting plate 18 is driven by a first motor 20, a second rotating shaft is arranged on the top of the second connecting plate 19, and a second motor 21 is arranged on the top of the second rotating shaft. The first motor 20 and the second motor 21 can drive the hollow mounting shell 2 to change in various azimuth angles, thereby adjusting the changes in different azimuths and different angles of the machine vision camera body 1, thereby improving its flexibility.

[0053] The working principle of the utility model is as follows: first, the mounting plate 3 drives the machine vision camera body 1 to enter the mounting groove 5. At this time, a circular channel can be formed between the first arc groove 4, the second arc groove 6 and the third arc groove 7. By pulling the limit plate, the limit plate drives the movable rod 14 to make the fixed plate 15 withdrawn from the second fixing hole 17 and squeeze the spring 16, so that the rotating plate 13 can be rotated, and the rotating plate 13 drives the first rotating shaft 10 to rotate, and the first rotating shaft 10 drives the semicircular fixed plate 8 to rotate, so that the circular channel formed by the first arc groove 4, the second arc groove 6 and the third arc groove 7 rotates, and the mounting plate 3 is connected with the hollow mounting shell 2 during rotation, so as to complete the installation. When the semicircular fixed plate 8 is fixed, the elastic force of the spring 16 makes the fixed plate 15 enter the second fixing hole 17 and lock it, so as to improve the fixing effect. By making the second arc plate slide between the first arc plate and the second arc plate, the diameter of the circle can be adjusted, and the size of the semicircular fixed plate 8 can be adjusted, so as to adapt to the fixing of different machine vision camera bodies 1. The device is not only convenient to install and disassemble, thus saving time and effort, but also has a stable fixing effect and is suitable for fixing different machine vision camera bodies 1.

[0054] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
