Description

Technical Field

[0001] This utility model relates to the field of visual positioning technology, and in particular to a visual positioning device for mounting parts. Background Technology

[0002] Vision positioning refers to the technology of capturing images of target objects using visual devices such as cameras and image sensors, and then combining them with image processing algorithms to accurately identify the position, angle, shape, and other information of the objects, and output coordinate data to guide machines to perform precise operations.

[0003] In the field of visual positioning, a robotic arm or a pick-and-place tool is generally used to pick up the component and move it to the position of the camera to acquire an image. The positioning algorithm in the vision software is used to locate the acquired image, and then the actual position of the component is located by converting the image coordinates to physical coordinates. Finally, the two components are mounted.

[0004] However, the accuracy of visual positioning mainly depends on the manufacturing precision of the camera, the method of image acquisition, and the quality of the visual algorithm. Existing image acquisition methods use multiple cameras for calibration, which is complex and prone to positional drift, requiring frequent calibration. After long-term use, calibration errors will appear, affecting the placement accuracy of components and increasing the number of defective products.

[0032] To illustrate the technical solution described in this utility model, specific embodiments are described below, showing only the parts related to the embodiments of this utility model.

[0033] Example:

[0034] like Figure 1-4 As shown, this utility model provides a visual positioning device for mounting components, including: a first visual positioning mechanism 1, a second visual positioning mechanism 2, and a suction mechanism 3; the first visual positioning mechanism 1 and the second visual positioning mechanism 2 are arranged side by side, and the suction mechanism 3 is arranged opposite to the first visual positioning mechanism 1 and the second visual positioning mechanism 2; the suction mechanism 3 includes a suction member 31, the top of the suction member 31 is provided with a calibration feature 32, and the end opposite to the top of the suction member 31 is provided as a suction part 33 for suctioning the first component 4 to be mounted; wherein, the suction member 31 can move in position in the X-axis direction, Y-axis direction, Z-axis direction, and R-axis direction; the first visual positioning mechanism 1 includes a first imaging structure 11 and a second imaging structure 12. The first shooting structure 11 and the second shooting structure 12 are symmetrically arranged in the axial direction. When the suction mechanism 3 is located in the first visual positioning mechanism 1, the first shooting structure 11 is used to shoot the calibration feature 32 on the top of the suction member 31, and the second shooting structure 12 is used to shoot the first element 4 sucked by the suction part 33. The second visual positioning mechanism 2 includes a first shooting component 21 and a second shooting component 22, which are coaxial and in the same direction. The first shooting component 21 is aligned with the second element 5 to be mounted and is used to shoot the positioning feature on the second element 5. When the suction mechanism 3 is located in the second visual positioning mechanism 2, the second shooting component 22 is used to shoot the calibration feature 32 on the top of the suction member 31.

[0035] The mounting component visual positioning device described in this embodiment uses a first visual positioning mechanism 1, a second visual positioning mechanism 2, and a pick-up mechanism 3 to achieve visual positioning between mounting components. Specifically, the pick-up mechanism 3 is used to pick up the first component 4. The first visual positioning mechanism 1 can photograph the calibration feature 32 on the pick-up mechanism 3 and the first component 4 picked up by the pick-up mechanism 3, and locate the positions of the calibration feature 32 on the pick-up mechanism 3 and the first component 4 to obtain the relative positional relationship between the calibration feature 32 on the pick-up mechanism 3 and the first component 4. The second visual positioning mechanism 2 can photograph the second component 5 and the calibration feature 32 on the pick-up mechanism 3, and locate the positions of the positioning features in the second component 5 and the calibration feature 32 on the pick-up mechanism 3, finally obtaining the relative positional relationship between the first component 4 and the second component 5. In this embodiment, the first component 4 can be a chip, and the second component 5 can be a circuit board.

[0036] It should be noted that the first visual positioning mechanism 1, the second visual positioning mechanism 2, and the suction mechanism 3 can all be located on the same supporting mechanism to achieve their respective functions.

[0037] The combination of the first visual positioning mechanism 1, the second visual positioning mechanism 2, and the suction mechanism 3 described in this embodiment can accurately position the first component 4 and the second component 5, obtain the positional relationship between the first component 4 and the second component 5, improve the accuracy of positioning, improve the accuracy of subsequent mounting, and ultimately improve the mounting quality and mounting efficiency of the components.

[0038] Below, in conjunction with Figure 1-4 The visual positioning device for mounting parts described in this embodiment will be described in detail.

[0039] The visual positioning device for mounting components includes a suction mechanism 3, a first visual positioning mechanism 1, and a second visual positioning mechanism 2. The first visual positioning mechanism 1 and the second visual positioning mechanism 2 are arranged side by side, and the suction mechanism 3 is arranged opposite to the first visual positioning mechanism 1 and the second visual positioning mechanism 2.

[0040] like Figure 2 As shown, the suction mechanism 3 includes a suction member 31, a calibration feature 32 is provided on the top of the suction member 31, and a suction part 33 is provided at the end opposite to the top of the suction member 31. The suction part 33 is used to pick up the first component 4 to be mounted.

[0041] Specifically, such as Figure 2 and Figure 4 As shown, a calibration feature 32 is provided on the top of the suction member 31 to facilitate the first visual positioning mechanism 1 and the second visual positioning mechanism 2 in obtaining the position of the suction member 31. This allows for the establishment of a connection between the first element 4 and the second element 5 based on the position of the suction member 31, facilitating subsequent acquisition of the positional relationship between the suction mechanism 3, the first element 4, and the second element 5, and enabling the positioning of the first element 4 and the second element 5. In this embodiment, the calibration feature 32 is set to a cross shape. In subsequent processing, the unique geometric characteristics of the cross shape (such as central symmetry and ease of identification) are utilized to more conveniently perform feature matching, positioning, and other operations.

[0042] More specifically, such as Figure 2 and Figure 4 As shown, a suction part 33 is provided at one end opposite to the top of the suction member 31. The suction part 33 is used to suction the first element 4. The position of the first element 4 after suction can be obtained by the first visual positioning mechanism 1. After suction, the first element 4 will be adjusted in position by the suction mechanism 3 and then attached to the second element 5.

[0043] In addition, the suction mechanism 3 also includes a mounting base (not shown in the figure) and a moving component (not shown in the figure). The suction member 31 is connected to the mounting base via the moving component. Specifically, the suction member 31 is correspondingly disposed on the mounting base with the first visual positioning mechanism 1 and the second visual positioning mechanism 2, and the suction member 31 can move in the X-axis, Y-axis, and Z-axis directions of the mounting base under the action of the moving component. That is, the suction member 31 can move into the first visual positioning mechanism 1 and the second visual positioning mechanism 2 under the action of the moving component, and the first visual positioning mechanism 1 and the second visual positioning mechanism 2 will take pictures. In this embodiment, the moving component consists of an X-axis moving component, a Y-axis moving component, and a Z-axis moving component to drive the suction member 31 to move in the X-axis, Y-axis, and Z-axis directions. In this embodiment, the X-axis moving component, Y-axis moving component, and Z-axis moving component are not specifically limited.

[0044] When the suction member 31 moves into the first visual positioning mechanism 1 under the action of the moving component, the first visual positioning mechanism 1 will photograph the calibration feature 32 on the top of the suction member 31 and the first element 4 being suctioned by the suction member 31 to obtain the positional relationship between the calibration feature 32 on the suction member 31 and the first element 4. When the suction member 31 moves into the second visual positioning mechanism 2 under the action of the moving component, the second visual positioning mechanism 2 will photograph the calibration feature 32 on the top of the suction member 31 to obtain the positional relationship between the first element 4 and the second element 5.

[0045] It should also be noted that the suction part 33 of the suction member 31 can rotate in the R-axis direction of the suction member 31 to rotate the angle of the first element 4, which facilitates the accurate subsequent mounting of the first element 4 onto the second element 5. Specifically, the suction part 33 can be connected to the suction member 31 using a rotating member, but this is not specifically limited in this embodiment.

[0046] like Figure 1 As shown, the first visual positioning mechanism 1 includes a first imaging structure 11 and a second imaging structure 12. The first imaging structure 11 and the second imaging structure 12 are symmetrically arranged in the axial direction and are both fixedly mounted on the fixed base 13. The imaging directions of the first imaging structure 11 and the second imaging structure 12 are also symmetrical.

[0047] For example, the shooting direction of the first shooting structure 11 is downward, and the shooting direction of the second shooting structure 12 is upward. When the suction member 31 of the suction mechanism 3 suctions the first element 4 into the first visual positioning mechanism 1, the shooting direction of the first shooting structure 11 is downward, and it captures the calibration feature 32 on the top of the suction member 31; the shooting direction of the second shooting structure 12 is upward, and it captures the first element 4 sucked by the suction part 33 of the suction member 31.

[0048] The purpose of the first visual positioning mechanism 1 in taking pictures of the suction component and the first element 4 sucked by the suction component is to obtain the positioning features on the top of the suction component 31 and the positional relationship between the first element 4 sucked by the suction part 33, and to position the first element 4 so as to facilitate the accurate placement between the first element 4 and the second element 5 in the future.

[0049] It should be noted that, as Figure 1 As shown, the first shooting structure 11 and the second shooting structure 12 have the same structure, both including a camera and a lens. The first shooting structure 11 includes a first camera 111 and a first lens 112, and the second shooting structure 12 includes a second camera 121 and a second lens 122. Both the first shooting structure 11 and the second shooting structure 12 achieve shooting through the cooperation of the camera and the lens.

[0050] It should also be noted that the distance between the first imaging structure 11 and the second imaging structure 12 matches the height of the suction member 31 after it has picked up the first element 4. Limiting the distance between the first imaging structure 11 and the second imaging structure 12 facilitates the first imaging structure 11 and the second imaging structure 12 in respectively photographing the calibration feature 32 on the top of the suction member 31 and the first element 4 picked up by the suction part 33 in the suction member 31, thus facilitating the positioning of the calibration feature 32 and the first element 4 on the suction member 31.

[0051] like Figure 3 As shown, the second visual positioning mechanism 2 includes a first shooting component 21 and a second shooting component 22, which are coaxial and in the same direction for shooting. Specifically, the second visual positioning mechanism 2 also includes a mounting plate 23, to which both the first shooting component 21 and the second shooting component 22 are fixedly connected and arranged side by side.

[0052] The first imaging component 21 includes a third camera 211 and a third lens 212, which are connected and cooperate to capture images of the second element 5. Specifically, the visual positioning device also includes a support platform 6, located directly below the first imaging component 21, for supporting the second element 5. The second element 5 has positioning features. After being placed on the support platform 6, the second element 5 is directly within the imaging range of the first imaging component 21, facilitating the acquisition of these positioning features by the first imaging component 21.

[0053] The second imaging assembly 22 includes a fourth camera 221, a fourth lens 222, and a reflector 223. The fourth camera 221 and the fourth lens 222 are connected, and the reflector 223 is used to fold the imaging light path emitted by the fourth lens 222. Specifically, the fourth camera 221 and the fourth lens 222 are connected and can cooperate to capture images of the top calibration feature 32 of the suction member 31 that has moved into the second visual positioning mechanism 2. It should be noted that, as Figure 3 As shown, the second shooting component 22 and the first shooting component 21 are arranged side by side under the action of the mounting plate 23. However, the first shooting component 21 and the second shooting component 22 are coaxial and in the same direction during the shooting process. Therefore, in order to make the second shooting component 22 coaxial and in the same direction as the first shooting component 21, a reflector 223 is provided on the second shooting component 22. The reflector 223 is used to fold the shooting light path emitted by the fourth lens 222, such as... Figure 3 As shown. In this embodiment, the reflector 223 is a 45° reflector 223.

[0054] In addition, such as Figure 3 As shown, the second imaging component 22 also includes a beam splitter 224. The beam splitter 224 is located on the imaging optical path of the first imaging component 21 and the imaging optical path of the second imaging component 22. The beam splitter 224 is used to adjust the imaging optical path of the second imaging component 22. Specifically, the beam splitter 224 is located on the imaging optical path of the first imaging component 21 and the imaging optical path of the second imaging component 22. After the reflector 223 in the second imaging component 22 folds the imaging optical path emitted by the fourth lens 222, the imaging optical path of the second imaging component 22 will be folded again under the action of the beam splitter 224, so that the imaging optical path of the second imaging component 22 coincides with the imaging optical path of the first imaging component 21. More specifically, the beam splitter 224 is also located on the imaging optical path of the first imaging component 21. Although the beam splitter 224 will extend the optical path of the first imaging component 21, it will not affect the imaging effect of the first imaging component 21. It should be noted that since the beam splitter 224 will extend the optical path of the first imaging component 21, the position and height of the first imaging component 21 need to be adjusted accordingly to ensure the shooting quality and shooting effect.

[0055] In this embodiment, the third lens 212 in the first shooting component 21 and the fourth lens 222 in the second shooting component 22 are both telephoto and telephoto lenses.

[0056] In this embodiment, the first shooting component 21 and the second shooting component 22 can project the shooting light path from different angles to coaxial and directional but different depth positions for shooting.

[0057] The first imaging component 21 acquires the positioning features of the second element 5 on the support platform 6. When the first imaging component 21 acquires the positioning features of the second element 5, the suction component has not yet moved into the second visual positioning mechanism 2. In this embodiment, the timing of the first imaging component 21 acquiring the positioning features of the second element 5 can be controlled to occur when the suction mechanism 3 is located in the first visual positioning mechanism 1 and being photographed by the first visual positioning mechanism 1. The second imaging component 22 captures the image when the suction mechanism 3 moves into the second visual positioning mechanism 2, photographing the calibration feature 32 on the top of the suction member 31 in the suction mechanism 3. By combining the corresponding images captured by the first visual positioning mechanism 1 and the second visual positioning mechanism 2, the positional relationship between the first element 4 and the second element 5 can be obtained.

[0058] In this embodiment, the first shooting component 21 in the second visual positioning mechanism 2 is used to obtain the position of the positioning feature of the second element 5 on the support platform 6. The second shooting mechanism captures the position of the calibration feature 32 on the top of the suction member 31. Finally, based on the positional relationship between the calibration feature 32 on the top of the suction member 31 and the first element 4, the position of the positioning feature of the second element 5, and the position of the calibration feature 32 on the top of the suction member 31 in the second visual positioning mechanism 2, the positional relationship between the first element 4 and the second element 5 is determined.

[0059] It should be noted that, as Figure 3 As shown, the distance between the first imaging component 21 and the support platform 6 in the second visual positioning mechanism 2 is greater than the height of the suction component 31. Specifically, since the third lens 212 and the fourth lens 222 in the first imaging component 21 and the second imaging component 22 are both telephoto and near-photophoto lenses, the height between the first imaging component 21 and the support platform 6 needs to be limited in order to ensure the accuracy of the imaging by the first imaging component 21 and the second imaging component 22. At the same time, after obtaining the positional relationship between the first element 4 and the second element 5, the suction component 31 in the suction component will be driven by the moving component to press down, attaching the first element 4 and the second element 5. In order to meet the attachment requirements of the first element 4 and the second element 5, it is also necessary to limit the height between the first imaging component 21 and the support platform 6.

[0060] It should also be noted that, such as Figure 2 As shown, the length and width of the suction part 33 of the suction member 31 are both smaller than the length and width of the first element 4. This arrangement is to facilitate the second vision component in the first vision positioning mechanism 1 to accurately acquire the image of the first element 4, accurately capture the image of the outer contour of the first element 4, avoid mistaking the outer contour of the suction part 33 for the outer contour of the first element 4, and at the same time facilitate the suction member 31 to pick up the first element 4, and facilitate the mounting of the first element 4 and the second element 5.

[0061] The embodiment is merely a special case and does not indicate that this utility model is implemented in such a way.

[0062] The above description is merely a preferred embodiment of the present utility model. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present utility model. Furthermore, under the teachings of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of the present utility model.
