Description

Technical Field

[0001] This utility model relates to the technical field of machine vision inspection, and in particular to an adjustment device for an inspection terminal and a machine vision inspection device. Background Technology

[0002] In modern industrial manufacturing and automated production, machine vision inspection has become a key technology for ensuring product quality and improving production efficiency. Machine vision inspection relies on inspection terminals (such as cameras) to capture images and then analyze, identify, and measure the target objects in the images.

[0003] Currently, the debugging process of machine vision inspection systems faces numerous challenges. Among them, the precise adjustment of the inspection terminal's position is crucial, directly impacting the accuracy and reliability of the inspection. Existing technologies have limitations in adjusting machine vision inspection. Traditional adjustment methods can only operate on the inspection terminal in limited dimensions, such as simple linear translation or rotational adjustment along a single axis. This single-dimensional adjustment method cannot meet the demands of multi-angle, omnidirectional, and precise positioning of the inspection terminal in complex inspection scenarios. Because it cannot simultaneously consider the coordinated adjustment of multiple dimensions, the inspection terminal often struggles to obtain the optimal shooting angle and image quality for the target object, resulting in deviations in the inspection results and failing to achieve ideal inspection accuracy. This hinders the further development of machine vision inspection technology in high-standard inspection. Utility Model Content

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the embodiments of the present utility model.

[0045] This utility model embodiment provides an adjustment device for a detection terminal, which can be applied to the yaw angle and yaw angle adjustment of the detection terminal in machine vision inspection. The adjustment device includes a support block 1, a first connecting member 4, a second connecting member 5, and a first adjustment mechanism 6.

[0046] Please see Figure 1 , Figure 1The structure of the support block 1 is illustrated, with a first rotating shaft 2 and a second rotating shaft 3 arranged perpendicularly to each other along the length of the support block 1. Mutually perpendicular shaft holes can be formed on the support block 1, and the first rotating shaft 2 and the second rotating shaft 3 can be installed into the two shaft holes respectively, thus making the first rotating shaft 2 and the second rotating shaft 3 perpendicular to each other. The support block 1 can be a cylinder or a rectangle, as long as it can accommodate the first rotating shaft 2 and the second rotating shaft 3; no specific limitation is made here. For example, the cross-section of the support block 1 is rectangular, the support block 1 has a second shaft hole for installing the first rotating shaft 2 in the vertical direction, and a third shaft hole for installing the second rotating shaft 3 in the horizontal direction.

[0047] Please see Figure 2 and Figure 3 The first connecting member 4 is connected to the first rotating shaft 2. The first connecting member 4 has a first mounting hole 43 for connecting the detection terminal 8. The first mounting hole 43 can be a threaded hole to facilitate the installation of the detection terminal 8 on the first connecting member 4. The second connecting member 5 is connected to the second rotating shaft 3. The second connecting member 5 has a second mounting hole 54 for fixing it. The second connecting member 5 can be installed on the frame of the machine vision inspection equipment or on other fixed parts.

[0048] The first adjustment mechanism 6 is connected to the support block 1. The first adjustment mechanism 6 is used to push the first connecting member 4 to rotate around the first rotating shaft 2 to adjust the yaw angle of the detection terminal 8. The first adjustment mechanism 6 is also used to push the second connecting member 5 to rotate around the second rotating shaft 3 to adjust the pitch angle of the detection terminal 8. The first adjustment mechanism can be an electric telescopic rod or other mechanism that can pull the first connecting member 4 and the second connecting member 5 to deflect around their rotating shafts.

[0049] When it is necessary to adjust the sway angle of the detection terminal 8, the first adjustment mechanism 6 applies a suitable thrust to the first connecting member 4. This thrust, with the first rotating shaft 2 as the center of rotation, drives the first connecting member 4 to rotate around the first rotating shaft 2. Since the first connecting member 4 is connected to the detection terminal 8, the detection terminal 8 also rotates synchronously, thereby achieving the purpose of adjusting the sway angle. During the pushing process, the first adjustment mechanism 6 can achieve high-precision adjustment of the sway angle by precisely controlling the magnitude and direction of the thrust.

[0050] Similarly, when adjusting the pitch angle of the detection terminal 8, the first adjustment mechanism 6 can apply a corresponding thrust to the second connecting member 5, pushing the second connecting member 5 to rotate around the second rotating shaft 3, thereby causing the detection terminal 8 to change its angle in the pitch direction. The connection method between the first adjustment mechanism 6 and the bearing block 1 ensures that it has stable support when the thrust is applied, and will not be displaced or shaken due to reaction forces or other factors, thus ensuring the smoothness and reliability of the adjustment process.

[0051] The first adjustment mechanism 6 can achieve the above functions in various forms. For example, it can be an electric push rod structure, in which the push rod is driven to extend and retract by a motor. The extension and retraction of the push rod is converted into a thrust on the connecting parts. The extension and retraction of the push rod can be precisely controlled by devices such as encoders, thereby achieving precise angle adjustment. Alternatively, it can be a manual adjustment structure consisting of a lead screw and nut mechanism and a handle. When the operator turns the handle, the lead screw rotates, causing the nut to produce a linear displacement. This displacement is converted into a thrust acting on the first connecting part 4 and the second connecting part 5. At the same time, the lead screw has scale markings to facilitate the operator to accurately control the adjustment angle.

[0052] For example, the first adjustment mechanism 6 includes a first fixing plate 61, at least one first bolt 62 and at least one second bolt 63.

[0053] The first fixing plate 61 is fixedly connected to the bearing block 1; the first bolt 62 is installed in the first screw hole of the first fixing plate 61, and the threaded end of the first bolt 62 is in close contact with the first connecting piece 4; the second bolt 63 is installed in the second screw hole of the first fixing plate 61, and the threaded end of the second bolt 63 is in close contact with the second connecting piece 5.

[0054] The first fixing plate 61 is fixedly connected to the bearing block 1, providing a stable installation base for the first adjustment mechanism 6. This ensures that the first bolt 62 and the second bolt 63 will not wobble or shift due to force during operation, guaranteeing the stability of the adjustment action. The first bolt 62 is installed in the first screw hole of the first fixing plate 61, with its threaded end tightly against the first connecting member 4. By rotating the first bolt 62, the threaded pushing action can apply a precise thrust to the first connecting member 4, thereby pushing the first connecting member 4 to rotate around the first rotating shaft 2, thus adjusting the yaw angle of the detection terminal 8. Similarly, the second bolt 63 is installed in the second screw hole of the first fixing plate 61, with its threaded end tightly against the second connecting member 5. Rotating the second bolt 63 can push the second connecting member 5 to rotate around the second rotating shaft 3, thereby adjusting the pitch angle of the detection terminal 8.

[0055] For further details, please refer to Figure 1 and Figure 4 There are two bolts, one first bolt 62 and one second bolt 63. The two first bolts 62 are spaced apart on the horizontal center line of the first fixing plate 61, and the two second bolts 63 are spaced apart on the vertical center line of the first fixing plate 61. This symmetrical distribution makes the thrust applied to the first connecting member 4 and the second connecting member 5 more reliable. After adjustment by one of the first bolts 62, it can be tightly fixed by the other first bolt 62. It can be understood that setting two of each first bolt 62 and second bolt 63 makes the adjustment of the yaw angle and pitch angle more flexible, ensuring the smoothness of the adjustment process and the accuracy and stability of the angle of the detection terminal 8 after adjustment.

[0056] Although the first adjustment mechanism 6 can adjust the yaw and pitch angles of the detection terminal 8, in practical applications, relying solely on these two dimensions is sometimes insufficient to ensure that the detection terminal 8 is accurately aligned with a specific area of ​​the product to be inspected or to adapt to more complex production line layouts and product posture changes. Therefore, in one specific embodiment, the adjustment device further includes a second adjustment mechanism 7.

[0057] The second adjustment mechanism 7 is connected to the second connecting member 5 and is used to adjust the rotation angle of the second connecting member 5 around the support block 1. The second adjustment mechanism 7 can be implemented in various ways. For example, it can be composed of a worm gear and worm assembly, where the worm gear is fixedly connected to the second connecting member 5, and the worm is driven by a motor or manually operated by a handle. Utilizing the transmission characteristics of the worm gear and worm, when the worm rotates, it drives the worm gear, thereby causing the second connecting member 5 to rotate around the support block 1, thus achieving angle adjustment. Alternatively, a structure combining a rotating shaft and an angle encoder can be used. One end of the rotating shaft is connected to the second connecting member 5, and the other end is connected to an angle encoder. The operator rotates the rotating shaft or drives it with a motor, causing the second connecting member 5 to rotate. The angle encoder can provide real-time feedback of the rotation angle information, facilitating precise control of the rotation angle and thus accurately adjusting the rotation angle of the second connecting member 5 around the support block 1, thereby affecting the overall angle state of the detection terminal 8.

[0058] For example, the second adjustment mechanism 7 includes a second fixing plate 71, a third connecting plate 72, a fourth connecting plate 73, and an adjustment assembly 74.

[0059] The second fixing plate 71 has a cavity for accommodating the second connector 5; the third connecting plate 72 is connected to both the second connector 5 and the second fixing plate 71; the fourth connecting plate 73 is also connected to both the second connector 5 and the second fixing plate 71. Both the third connecting plate 72 and the fourth connecting plate 73 are used to install the second connector 5 within the cavity; the adjusting component 74 is mounted on the second fixing plate 71 and is used to adjust the rotation angle of the second connector 5 within the cavity. The third connecting plate 72 and the fourth connecting plate 73 are both connected to the second connector 5 and the second fixing plate 71, working together to install the second connector 5 within the cavity. Through the third connecting plate 72 and the fourth connecting plate 73, the second connector 5 can be fixed in a suitable position within the cavity. When it is necessary to adjust the rotation angle of the detection terminal 8, the third connecting plate 72 and the fourth connecting plate 73 can be loosened, the angle of the detection terminal 8 can be adjusted using the adjusting component 74, and then the third connecting plate 72 and the fourth connecting plate 73 can be locked back in place.

[0060] For example, the adjustment assembly 74 includes four screws; see [link to relevant documentation]. Figure 5The adjusting component 74 specifically consists of a first screw 741, a second screw 742, a third screw 743, and a fourth screw 744. Four threaded holes are opened on a set of parallel opposite sides of the cavity, and each screw is installed into a corresponding threaded hole. The rotation angle of the second connector 5 in the cavity is adjusted by the four screws.

[0061] To further improve the stability of the adjustment, the adjustment device also includes an elastic component. One end of the elastic component is tightly attached to the first connecting member 4, and the other end is tightly attached to the second connecting member 5. Please continue reading. Figure 2 Four spring mounting holes 55 can be opened on the second connector 5, and four compression springs can be installed in the four spring mounting holes 55 respectively, so that there is an elastic force between the first connector 4 and the second connector 5. After the yaw angle is adjusted, the first connector 4 responds to the rotation in time based on the elastic force.

[0062] Specifically, the first connecting member 4 is provided with a first clearance hole 41, and the first connecting member 4 is provided with a first shaft hole 42 in the vertical direction. The first shaft hole 42 passes through the first clearance hole 41. The bearing block 1 is fitted into the first clearance hole 41, and the first rotating shaft 2 is installed in the first shaft hole 42. The first clearance hole 41 allows the first connecting member 4 and the bearing block 1 to be fitted together, which facilitates the adjustment of the lateral angle.

[0063] Similarly, please see Figure 5 The second connecting member 5 is provided with a second clearance hole 51. A first groove 52 and a second groove 53 are respectively provided on both sides of the second clearance hole 51 in the horizontal direction. The bearing block 1 is fitted into the second clearance hole 51, and the two ends of the second rotating shaft 3 are respectively installed in the first groove 52 and the second groove 53. Since machining the horizontal shaft hole of the second connecting member 5 is difficult, the first groove 52 and the second groove 53 are provided to allow the second rotating shaft 3 to rotate. Both the first groove 52 and the second groove 53 are fitted with the second rotating shaft 3 with a clearance fit.

[0064] Please see Figure 6 , Figure 6 The installation structure of the detection terminal 8 is illustrated. The detection terminal 8 can be an electronic detection component composed of a camera, processor and other components. It can take pictures of the items to be inspected and perform machine vision inspection based on the captured images.

[0065] Based on the same technical concept as the adjustment device, this utility model embodiment also provides a machine vision inspection device, which includes any of the above-mentioned adjustment devices.

[0066] The technical solution provided in this embodiment of the utility model has at least the following technical effects or advantages:

[0067] The technical solution of this utility model embodiment includes a support block, a first connector, a second connector, and a first adjustment mechanism. The support block has a first rotating shaft and a second rotating shaft spaced perpendicularly to each other along its length. The first connector is connected to the first rotating shaft, the second connector is connected to the second rotating shaft, and the first adjustment mechanism is connected to the support block. The first adjustment mechanism is used to push the first connector to rotate around the first rotating shaft to adjust the yaw angle of the detection terminal. The first adjustment mechanism is also used to push the second connector to rotate around the second rotating shaft to adjust the pitch angle of the detection terminal. This technical solution allows for yaw and pitch angle adjustment of the detection terminal connected to the first connector. During debugging, the detection terminal can perform angle adjustments in both pitch and yaw dimensions based on adjustment requirements, thereby reducing the limitations of position adjustment and facilitating machine vision inspection based on the optimal shooting angle.
