Description

Technical Field

[0001] This application relates to the field of machine vision inspection technology, and in particular to a vision inspection calibration platform. Background Technology

[0002] Machine vision inspection is a technology that uses optical sensors (such as cameras) to capture images or videos, and then analyzes the image information through computer algorithms to perform tasks such as object recognition, measurement, localization, and defect detection. Compared to manual inspection, machine vision has advantages such as high speed, high accuracy, good stability, and wide applicability, and therefore has been widely used in many fields. For example, in the field of medical device technology, machine vision inspection can be used to calibrate the end effector of surgical robots. Because surgical robots have high precision requirements, machine vision inspection can ensure accuracy and avoid surgical risks compared to manual calibration.

[0003] Existing calibration equipment is diverse, but each has its shortcomings. For example, a machine vision inspection platform with patent number CN221377894U only has one camera, resulting in non-stereoscopic imaging and low inspection accuracy. Similarly, a machine vision inspection platform with automatic leveling function in patent number CN214722791U can perform equipment calibration and inspection, but the equipment, camera, and light source cannot be moved or their angles adjusted, leading to a single detection angle and the inability to achieve multi-directional imaging. In short, existing equipment is either structurally complex and expensive, has a fixed camera and light source with no angle adjustment leading to a single detection angle, or has dim lighting resulting in unclear imaging.

[0004] Therefore, a visual inspection and calibration platform needs to be designed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] According to the visual inspection and calibration platform provided by this utility model, such as Figures 1 to 4 As shown, the visual inspection and calibration platform is used for, for example, position detection of the end effector of a surgical robot. The visual inspection and calibration platform includes a calibration base plate 1, a first detection unit 2, a second detection unit 3, and a workpiece adjustment unit 4.

[0029] In the following description, reference will be made to Figures 1 to 4The detailed structure of the calibration base plate 1, the first inspection unit 2, the second inspection unit 3, and the workpiece adjustment unit 4 of the visual inspection calibration platform is described in detail. Furthermore, as... Figure 1 and Figure 2 As shown in the description of the embodiment, three directions are also involved: a first direction S1, a second direction S2, and a third direction S3. These three directions can be understood as the length direction, width direction, and height direction of the visual inspection calibration platform. Specifically, the first direction S1 can be understood as the direction from one end to the other in the length direction, or it can be understood as... Figure 1 and Figure 2 The direction shown is from right to left. The second direction S2 can be understood as the direction from one end to the other in the width direction, or it can be understood as... Figure 1 and Figure 2 The direction shown, from top to bottom, can be understood as the third direction S3 being... Figure 1 The direction from the bottom to the top of the visual inspection calibration platform.

[0030] like Figures 1 to 3 As shown, in this embodiment, the first detection unit 2 may include a first detection element 8 and a first adjustment component. The first detection element 8 is disposed on the calibration base plate 1 via the first adjustment component. The second detection unit 3 may include a second detection element 9 and a second adjustment component. The second detection element 9 is disposed on the calibration base plate 1 via the second adjustment component. The test piece adjustment unit 4 may include a test piece body 10 and a third adjustment component. The test piece body 10 is disposed on the calibration base plate 1 via the third adjustment component. The test piece body 10 can be positioned at the intersection of the axis of the first detection element 8 and the axis of the second detection element 9. The test piece body 10 may be, for example, the end effector of a surgical robot. In this embodiment, the end effector of the surgical robot is a needle. This needle needs to have high precision during use. Since insufficient precision of the surgical robot's motor can lead to surgical risks, additional calibration and testing of the needle are required.

[0031] The two inspection components of this visual inspection and calibration platform are adjustablely positioned on the calibration base plate 1. Simultaneously, the workpiece body 10 can also be movably positioned on the calibration base plate 1. The cooperation of the two inspection components allows the workpiece body 10 to be calibrated. During calibration, the axis of the first inspection component 8 intersects with the axis of the second inspection component 9, and the workpiece body 10 can be positioned at this intersection. At this point, the workpiece body 10 can be inspected and further calibration can be easily performed.

[0032] This visual inspection and calibration platform, through the cooperation of the calibration base plate 1, the first detection unit 2, the second detection unit 3, and the workpiece adjustment unit 4, enables the detection and calibration of the workpiece body 10, thus facilitating user operation and ensuring the precise positioning of the workpiece body 10, avoiding usage risks. Through the cooperation of the first adjustment component, the second adjustment component, and the third adjustment component, the first detection component 8, the second detection component 9, and the workpiece body 10 can be individually adjusted in position, and their angles can be adjusted to achieve various detection angles, enabling multi-directional imaging and further increasing adjustment accuracy. Furthermore, since detection and calibration are completed collaboratively by the first detection component 8 and the second detection component 9, the imaging is three-dimensional, resulting in high detection accuracy. This visual inspection and calibration platform has a simple overall structure, is easy to assemble, provides fast and accurate imaging, is low in cost, economical, and can be applied to various occasions.

[0033] Preferably, such as Figures 1 to 3 As shown, in this embodiment, both the first adjustment component and the second adjustment component may include a connecting plate 501, a first adjustment member 502, and a second adjustment member 503. The connecting plate 501 is disposed on the calibration base plate 1, the first adjustment member 502 is disposed on the top of the connecting plate 501, the second adjustment member 503 is disposed on the top of the first adjustment member 502, and the first detection member 8 and the second detection member 9 are disposed on the second adjustment member 503. The first adjustment member 502 and the second adjustment member 503 can respectively drive the first detection member 8 or the second detection member 9 to move in different directions to calibrate the body 10 to be inspected.

[0034] Preferably, such as Figures 1 to 3 As shown, in this embodiment, the first adjusting member 502 can be adjusted in position along the first direction S1, and the second adjusting member 503 can be adjusted in position along the second direction S2, with the first direction S1 perpendicular to the second direction S2. Through the cooperation of the first adjusting member 502 and the second adjusting member 503, the first detection member 8 and the second detection member 9 can be adjusted in position along two perpendicular directions.

[0035] Preferably, such as Figures 1 to 4 As shown, in the embodiment, both the first adjusting component and the second adjusting component may further include a first connecting block 504, a first adjusting shaft 505, and a second adjusting shaft (not shown due to angle). In the embodiment, it is understood that the structures of the first adjusting member 502 and the second adjusting member 503 may be identical. Furthermore, the structures of the five adjusting members—the first adjusting member 502, the second adjusting member 503, the third adjusting member 602, the fourth adjusting member 603, and the fifth adjusting member 604—may all be identical. Therefore, in… Figure 4 In this description, the first adjusting member 502 is used as an example.

[0036] Specifically, the first adjusting shaft 505 passes through the first adjusting member 502 along its length, and the second adjusting shaft passes through the second adjusting member 503 along its length. The first connecting block 504 may include upper and lower parts. Figure 4 The diagram shows the lower part; the upper part has the same structure as the lower part, and the upper part is connected to the lower part by a threaded connection. The lower part of the first connecting block 504 is connected to the first adjusting shaft 505. When the first adjusting shaft 505 rotates, the first connecting block 504 can change its position along the length direction of the first adjusting shaft 505. The upper part of the first connecting block 504 is connected to the second adjusting shaft. When the second adjusting shaft rotates, the first connecting block 504 can change its position along the length direction of the second adjusting shaft. The lower part of the first connecting block 504 and the first adjusting shaft 505, and the upper part of the first connecting block 504 and the second adjusting shaft, can both be understood as a lead screw and nut structure. By rotating the first adjusting shaft 505 and the second adjusting shaft, the position of the first connecting block 504 can be changed. In the embodiment, the lower part and the upper part of the first connecting block 504 are fixedly connected to each other, and it can be understood that the first adjusting member 502 and the second adjusting member 503 are connected to each other through the lower part and the upper part of the first connecting block 504. Therefore, when the lower part of the first connecting block 504 moves in the first direction S1 by rotating the first adjusting shaft 505, the second adjusting member 503 also moves in the first direction S1. At this time, rotating the second adjustment shaft will cause the upper part of the first connecting block 504 to move in the second direction S2, so that the second adjustment member 503 can also move in the first direction S1. Since the first detection member 8 or the second detection member 9 is set on the second adjustment member 503, the first detection member 8 or the second detection member 9 can be changed in position by rotating the first adjustment shaft 505 and the second adjustment shaft.

[0037] Preferably, both the first adjustment shaft 505 and the second adjustment shaft can be provided with knob handles at their ends, so that the user can rotate the knob handles to drive the first adjustment shaft 505 and the second adjustment shaft to rotate.

[0038] Preferably, such as Figure 1 and Figure 3 As shown in the embodiment, the first adjustment component and the second adjustment component may further include a detection fixing member 506, and both the first detection member 8 and the second detection member 9 are disposed on the second adjustment member 503 via the detection fixing member 506. The detection fixing member 506 may be formed as a support mechanism for lifting the first detection member 8 and the second detection member 9. However, the structure of the detection fixing member 506 is not limited to that shown in the figure, and the user may select a detection fixing member 506 with a suitable structure as needed.

[0039] Preferably, such as Figure 1 and Figure 3As shown, in this embodiment, the test piece adjustment unit 4 may further include a height adjustment member 601, and the third adjustment component is disposed on the calibration base plate 1 via the height adjustment member 601. The height adjustment member 601 may be formed in a U-shape to adjust the height of the third adjustment component, so that the third adjustment component can also be adjusted in the height direction.

[0040] Preferably, such as Figure 1 and Figure 3 As shown, in this embodiment, the third adjustment component may include a third adjustment member 602, a fourth adjustment member 603, and a fifth adjustment member 604, which are arranged sequentially along the height direction. The height direction may be, for example, […]. Figure 1 The first direction S1. The test piece body 10 is connected to the fifth adjusting member 604. The test piece body 10 can be adjusted in three directions through the cooperation of the third adjusting member 602, the fourth adjusting member 603 and the fifth adjusting member 604.

[0041] Preferably, such as Figure 1 and Figure 3 As shown, in the embodiment, the third adjusting member 602 can adjust its position along the second direction S2, the fourth adjusting member 603 can adjust its position along the first direction S1, and the fifth adjusting member 604 can adjust its position along the third direction S3. The first direction S1, the second direction S2, and the third direction S3 are perpendicular to each other.

[0042] Preferably, such as Figure 1 and Figure 3 As shown, in this embodiment, the third adjustment component may further include a second connecting block, a third connecting block, a third adjusting shaft, a fourth adjusting shaft, and a fifth adjusting shaft (these structures are not shown due to angle; furthermore, the structures of the second and third connecting blocks are the same as those of the first connecting block 504, and the structures of the third, fourth, and fifth adjusting shafts are the same as those of the first adjusting shaft 505). The third, fourth, and fifth adjusting shafts can respectively pass through the third adjusting member 602, the fourth adjusting member 603, and the fifth adjusting member 604 along their length direction. The structures of the third adjusting member 602, the fourth adjusting member 603, and the fifth adjusting member 604 can be the same as those of the first adjusting member 505. Figure 4 The first adjusting element 502 shown is the same, so it will not be described again here.

[0043] Preferably, such as Figure 1 and Figure 3As shown, in this embodiment, the lower part of the second connecting block is connected to the third adjusting shaft, and the second connecting block can change its position along the length direction of the third adjusting shaft when the third adjusting shaft rotates; the upper part of the second connecting block is connected to the fourth adjusting shaft, and the second connecting block can change its position along the length direction of the fourth adjusting shaft when the fourth adjusting shaft rotates; the third connecting block is connected to the fifth adjusting shaft, and the third connecting block can change its position along the length direction of the fifth adjusting shaft when the fifth adjusting shaft rotates. See here. Figure 4 The connection method and transmission structure of the second connecting block, the third adjusting shaft, and the fourth adjusting shaft are the same as those of the first connecting block 504, the first adjusting shaft 505, and the second adjusting shaft, and will not be described again here. The connection and transmission method between the third connecting block and the fifth adjusting shaft is also the same as that of the lead screw and nut, and the structure is similar to... Figure 4 The same applies as shown, so I will not repeat it again.

[0044] Thus, the body 10 to be inspected can change its position in the second direction S2, the first direction S1 and the third direction S3 by the third adjustment member 602, the fourth adjustment member 603 and the fifth adjustment member 604 to ensure accuracy and precision.

[0045] Preferably, such as Figure 1 and Figure 3 As shown in the embodiment, the third adjustment component may further include a test fixture 605, through which the test body 10 is connected to the third connecting block. The test fixture 605 may also be a support structure for supporting the test body 10, and its structure is not limited to that shown in this figure. Users can select a test fixture 605 with a suitable structure as needed.

[0046] Preferably, such as Figure 1 and Figure 3 As shown, in this embodiment, the visual inspection calibration platform may further include a light-blocking plate 7, which is disposed on the calibration base plate 1 and surrounds the body 10 to be inspected, the first detection element 8, and the second detection element 9. The light-blocking plate 7 can be used to assist imaging.

[0047] Furthermore, in the description of the embodiments, the specific methods of connection, fixing, and setting can all be threaded connections. The first detection element 8 and the second detection element 9 can be a combination of an industrial camera and a light source, allowing the user to adjust the brightness of the light source and use the camera to take pictures and perform inspections. The combination of the industrial camera and the light source can be a common industrial camera lamp in the prior art, the structure and principle of which are known to those skilled in the art.

[0048] The assembly process of this visual inspection calibration platform is as follows: First, the calibration base plate 1 is placed on a horizontal platform. Two connecting plates 501 and a height adjustment component 601 are fixed by threaded connection. The positions of the two connecting plates 501 and the height adjustment component 601 can be selected according to the actual situation. Then, the first adjustment component 502 and the second adjustment component 503 are installed on each connecting plate 501, and the third adjustment component 602, the fourth adjustment component 603, and the fifth adjustment component 604 are installed on the height adjustment component 601. The detection fixing component 506 is installed on the top of the second adjustment component 503, and the first detection component 8 and the second detection component 9 are installed on the two detection fixing components 506 respectively. The positions of the first detection component 8 and the second detection component 9 are perpendicular to each other. The light sources of the first detection component 8 and the second detection component 9 are locked to the industrial camera, and the camera imaging is adjusted by manually adjusting the brightness of the light sources. The fixture 605 to be tested is installed on the fifth adjusting member 604. The position of the body 10 to be tested is adjusted by the third adjusting member 602, the fourth adjusting member 603, and the fifth adjusting member 604 so that the first detection member 8 and the second detection member 9 can correspond to the body 10 to be tested, thus obtaining a clear image. Finally, the light-blocking plate 7 is installed on the calibration base plate 1. The background of the light-blocking plate 7 is bright white, which allows the light from the light source to fully hit the light-blocking plate 7, making the projection of the body 10 to be tested clearer and the movement trajectory more obvious.

[0049] This visual inspection and calibration platform, through the cooperation of a calibration base plate, a first inspection unit, a second inspection unit, and a workpiece adjustment unit, enables the inspection and calibration of the workpiece itself, thus facilitating user operation and ensuring the precise positioning of the workpiece, avoiding usage risks. The cooperation of the first, second, and third adjustment components allows for individual position adjustment of the first and second inspection components and the workpiece itself, as well as angle adjustment to achieve diverse inspection angles and multi-directional imaging, further increasing adjustment accuracy. Furthermore, since inspection and calibration are completed collaboratively by the first and second inspection components, the imaging is three-dimensional, resulting in high inspection accuracy. This visual inspection and calibration platform has a simple overall structure, is easy to assemble, provides fast and accurate imaging, is low-cost, economical, and can be applied to various situations.
