Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, specifically to a mounting bracket for a visual inspection component. Background Technology

[0002] When using visual inspection technology to detect defects on the surface of a workpiece, the camera or light source needs to be positioned at different angles depending on the specific workpiece being inspected in order to achieve the best imaging and inspection results.

[0003] For example, in a camera rotation positioning device with patent application number CN202122375596.1, the camera is mounted on a horizontally arranged aluminum profile. The two ends of the aluminum profile are rotatably connected to a rotating component and fixed by the rotating component. The rotating component has an arc groove around the rotation axis of the aluminum profile, and a fastener screw is slidably arranged in the arc groove. The end of the aluminum profile has threaded holes arranged in a circumferential array corresponding to the arc groove. The angle of the aluminum profile is fixed by tightening the fastener screw.

[0004] When adjusting the above-mentioned device, the aluminum profile needs to be rotated manually. If the visual inspection component is heavy (such as a large camera with a lens and light source), the weight of the visual inspection component and the aluminum profile must be directly overcome when manually rotating the aluminum profile. Large-angle adjustments (such as from 0° to 45°) may require a lot of manpower, which reduces the ease of operation.

[0005] Furthermore, the aforementioned device relies solely on fasteners and screws to overcome the torque generated by the gravity of the visual inspection components. The force is concentrated at a single point, and when the component is heavy or frequently adjusted over a long period, the locking force will decrease, making it difficult to stably maintain the angle positioning of the aluminum profile. In fact, the angle may shift due to vibration or minor external forces during the inspection process, affecting the consistency of the inspection accuracy. Utility Model Content

[0006] To address the technical problems existing in the background art, this utility model provides a mounting bracket for a visual inspection component.

[0007] The technical solution of this utility model is as follows:

[0008] A visual inspection component mounting bracket includes two opposing legs, with a crossbar rotatably connected between the two legs, and a mounting base for mounting the visual inspection component on the crossbar.

[0009] Furthermore, one end of the crossbar extends to the outside of the support leg and is connected to a drive wheel. A driven wheel is rotatably provided on the outside of the support leg. The driven wheel and the drive wheel are driven by gear meshing. The rotation axis of the driven wheel is parallel to the crossbar. A fastening rod is axially threaded on the driven wheel. Multiple threaded holes are distributed on the outside of the support leg in the circumferential direction corresponding to the driven wheel. The inner end of the fastening rod can be threaded into any of the threaded holes.

[0010] In practical work, the adjustment of the crossbar rotation angle is achieved through the following steps:

[0011] Unlocking the angle lock: The operator first rotates the fastening rod on the driven wheel so that its inner end is unscrewed from the threaded hole of the outrigger, releasing the rigid connection between the driven wheel and the outrigger. At this time, the driven wheel can rotate freely, and the driving wheel and crossbar are also in a rotatable state.

[0012] Drive the crossbar to rotate: The drive wheel is driven to rotate by an external force. Since the drive wheel is rigidly connected to the crossbar, the crossbar rotates synchronously with the drive wheel, which in turn drives the vision detection component on the mounting base to rotate, thereby achieving angle adjustment. During this process, the drive wheel drives the driven wheel to rotate synchronously through gear meshing (the driven wheel rotates in the opposite direction to the drive wheel).

[0013] Locking the target angle: When the crossbar (and vision detection component) rotates to the target angle, the drive wheel stops. At this time, the driven wheel also stops in the corresponding position synchronously with the drive wheel. The operator rotates the fastening rod so that its inner end is screwed into the threaded hole at the corresponding position on the outrigger. The driven wheel is fixed by the threaded engagement between the fastening rod and the threaded hole. Then, the angle of the drive wheel and the crossbar is locked by the gear meshing relationship, thus completing the adjustment.

[0014] As one implementation method, the drive wheel is equipped with a rotating handle, which is parallel to the axis of the drive wheel.

[0015] Preferably, the length of the rotating handle is 1.5-2 times the radius of the drive wheel.

[0016] Furthermore, the driven wheel diameter is larger than the driving wheel diameter.

[0017] Preferably, the diameter of the driven wheel is 2-3 times the diameter of the driving wheel.

[0018] Furthermore, both the driving gear and the driven gear are cylindrical spur gears.

[0019] As a further implementation, the outer edge of the drive wheel is provided with an angle scale, and the support leg is provided with a corresponding pointer.

[0020] Furthermore, the central angle of the angle scale arranged along the outer edge of the drive wheel is 45°-120°.

[0021] Preferably, the graduation value of the angle scale is 5°.

[0022] Furthermore, the crossbar is made of aluminum profile, and the bottom of the mounting base slides into the groove of the aluminum profile along the length direction and is fixed to the aluminum profile by bolts.

[0023] The beneficial effects of this utility model are as follows: On the one hand, through the gear meshing transmission design of the driving wheel and the driven wheel, and with the help of the force-saving characteristics of gear transmission, the operator does not need to directly overcome the gravity of the vision inspection component and the crossbar. Even for heavy components or large-angle adjustments, the crossbar can be easily driven to rotate, greatly improving the convenience of operation. On the other hand, the angle locking is achieved by utilizing the meshing relationship between the driven wheel and the driving wheel. The locking force of the fastening rod on the driven wheel is transmitted to the driving wheel and the crossbar through the gear. This changes the situation in the prior art where only a single fastener screw bears the torque and the force point is single and concentrated. It effectively avoids the angle deviation problem caused by the decay of the locking force after long-term use, ensuring that the vision inspection component maintains a stable angle positioning during the inspection process and ensuring the consistency of inspection accuracy.

[0031] Combination Figures 1-3 This embodiment provides a visual inspection component mounting bracket for supporting heavy visual inspection components (such as large cameras with lenses and light sources), and for enabling large-angle adjustment and stable locking of the visual inspection component angle.

[0032] Specifically, the mounting bracket includes two opposing legs 1, with a crossbar 2 rotatably positioned between the two legs 1, and a mounting seat 3 for mounting the vision inspection component on the crossbar 2.

[0033] The two legs 1 are vertically mounted on the inner side with mounting rods 8. The mounting rods 8 are made of aluminum profiles. The two legs 1 are connected to the mounting rods 8 by T-bolts (standard parts, not shown in the figure). The T-heads of the T-bolts slide laterally with the grooves of the aluminum profiles along the length of the aluminum profiles. The studs of the T-bolts are threaded to the legs 1, so that the vertical height of the two legs 1 is adjustable, that is, the vertical height of the vision inspection component is adjustable.

[0034] The crossbar 2 is made of aluminum profile. When the visual inspection component is positioned at a fixed lateral position on the crossbar 2, the bottom of the mounting base 3 is in contact with the groove of the aluminum profile (see...). Figure 4 It slides along its length and is fixed to the aluminum profile with bolts, see details. Figure 4 The mounting base 3 has a slider at the bottom that slides into the groove of the aluminum profile. The bolt thread is located on the slider. The groove of the aluminum profile has a threaded hole at the installation position. The inner end of the bolt can be threaded into the corresponding threaded hole to fix the mounting base 3, thus completing the fixation of the visual inspection component on the crossbar 2.

[0035] Combination Figure 2 One end of the crossbar 2 extends to the outside of the support leg 1 and is connected to the drive wheel 4. The outside of the support leg 1 is provided with a driven wheel 5, which is driven by gear meshing. The axis of rotation of the driven wheel 5 is parallel to the crossbar 2. A fastening rod 6 is axially threaded on the driven wheel 5. Multiple threaded holes are distributed on the outside of the support leg 1 in the circumferential direction corresponding to the driven wheel 5. The inner end of the fastening rod 6 can be threaded into any of the threaded holes. The drive wheel 4 is provided with a rotating handle 7, which is parallel to the axis of the drive wheel 4 to maximize the use of the lever principle. An angle scale is also provided on the outer edge of the drive wheel 4, and a pointer 9 is provided on the support leg 1.

[0036] It should be noted that the number and position of the threaded holes on the outside of the outrigger 1 can be set according to the angles that need to be adjusted during actual use, and no further restrictions are imposed here.

[0037] In use, the operator first rotates the fastening rod 6 on the driven wheel 5 so that its inner end screws out of the threaded hole on the support leg 1. Then, by rotating the handle 7, the operator drives the driving wheel 4 to rotate. The rotation of the driving wheel 4 drives the crossbar 2 to rotate synchronously, which in turn drives the vision detection component on the mounting base 3 on the crossbar 2 to rotate, thereby achieving angle adjustment. During this process, the driving wheel 4 drives the driven wheel 5 to rotate synchronously through gear meshing. By observing the pointer 9 on the support leg 1 and the angle scale on the driving wheel 4, the operator observes that the driving wheel 4 stops rotating after rotating to the target angle. At this time, the crossbar 2 (and the vision detection component) and the driven wheel 5 also stop synchronously in the corresponding position along with the driving wheel 4. The operator then rotates the fastening rod 6 so that its inner end screws into the threaded hole at the corresponding position on the support leg 1. The driven wheel 5 is fixed by the threaded engagement between the fastening rod 6 and the threaded hole. Then, the angle of the driving wheel 4 and the crossbar 2 is locked by the gear meshing relationship, thus completing the adjustment.

[0038] The above adjustment process utilizes the rotating handle 7 and gear transmission to achieve effortless adjustment, and is combined with threaded connection to achieve reliable locking. It does not require directly overcoming the gravity of the vision inspection component, which solves the problem of laborious and inconvenient operation of traditional manual rotation of aluminum profile adjustment. It also changes the situation in the existing technology where only a single fastener screw bears the torque and the force point is single and concentrated, ensuring that the vision inspection component maintains a stable angular positioning during the inspection process and ensuring the consistency of inspection accuracy.

[0039] Combination Figure 2 The length of the rotating handle 7 is 1.5-2 times the radius of the drive wheel 4, which can ensure the labor-saving effect and avoid the problem of insufficient operating space on the production line caused by the excessive length of the rotating handle 7.

[0040] Combination Figure 3 The driven wheel 5 has a larger diameter than the driving wheel 4, which amplifies the force applied by the operator during rotation, effectively reducing the operational intensity when adjusting the angle of the vision inspection component, making it easier for the operator to complete the angle adjustment, especially suitable for scenarios where heavier vision inspection components are installed.

[0041] Based on the labor-saving effect, the size of the mounting bracket and the adjustment accuracy, it is preferable that the diameter of the driven wheel 5 is 2-3 times the diameter of the driving wheel 4, and both the driving wheel 4 and the driven wheel 5 are cylindrical spur gears. During the transmission process, the power transmission is stable and efficient, which can ensure reliable meshing transmission between the driving wheel 4 and the driven wheel 5, thereby ensuring the accuracy and smoothness of angle adjustment, and reducing manufacturing costs and assembly difficulty.

[0042] Combination Figure 3 The angle scale, arranged along the outer edge of the drive wheel 4, has a central angle ranging from 45° to 120°. This not only meets the angle adjustment requirements for common workpiece inspections, such as those on flat and curved surfaces, but also avoids excessively dense scales that could affect readings due to an overly large scale range. This allows operators to quickly and accurately read angle values. Preferably, the angle scale has a graduation of 5°, ensuring that the angle adjustment accuracy meets the requirements of most visual inspections. It also facilitates quick angle identification and reading by operators, reducing time costs during adjustment and improving work efficiency.
