Description

Technical Field

[0001] This utility model relates to the field of vision equipment technology, and more specifically, to a vision adjustment mechanism and automated equipment. Background Technology

[0002] When using vision systems on industrial equipment, multiple lenses are typically used in conjunction to combine the images captured by these lenses into the desired final shooting range. Since the positions of the lenses are generally fixed, and the shooting range is also fixed, changing the shooting range usually involves the following methods: 1. Extracting a smaller area from the original shooting range; 2. Changing the lens model and size to alter the vision shooting range; 3. Removing the lens from its original position and reassembling it to the desired location. All of these methods are quite cumbersome, and currently, there is a lack of a mechanical structure that allows for a more convenient way to change the shooting range. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides a visual adjustment mechanism, including a base, a transmission plate, a connecting rod, a bracket, and a first lens. The two ends of the connecting rod are rotatably connected to the transmission plate and the bracket, respectively. The base is provided with a first slide rail, and the bracket is slidably connected to the first slide rail. The first lens and the bracket are fixedly connected. When the transmission plate is rotated, the connecting rod drives the bracket to move on the first slide rail to change the shooting position of the first lens.

[0004] Optionally, a connecting piece is connected to the bracket, and a second lens is fixedly connected to the connecting piece. The connecting piece slides together with the bracket to change the shooting position of the second lens.

[0005] Optionally, the transmission plate includes a connecting part and a clearance part, the clearance part being located between two adjacent connecting parts, and one end of the connecting rod being rotatably connected to the connecting part. When the transmission plate is rotated to bring the bracket closer to the transmission plate, the clearance part is used to avoid the second lens.

[0006] Optionally, the first lens is located at the end of the bracket away from the transmission plate, the connecting piece is connected to the end of the bracket near the transmission plate, and the second lens is located at the end of the connecting piece near the transmission plate.

[0007] Optionally, a first slide block is connected to the bracket, and the first slide block and the first slide rail are slidably connected so that the bracket slides relative to the first slide rail.

[0008] Optionally, a third lens is connected to the bottom of the base, and a second slide rail is provided at the bottom of the base. The third lens is connected to a second slide block, and the second slide rail and the second slide block are slidably connected so that the third lens can slide on the second slide rail to change the shooting position.

[0009] Optionally, a connecting assembly is coaxially connected to the transmission plate. The connecting assembly includes a bearing housing and a motor housing that are connected to each other. The bearing housing contains a bearing, and the motor housing is connected to a motor. The motor is coaxially connected to the transmission plate to drive the transmission plate to rotate.

[0010] Optionally, the transmission plate has a connecting hole at its center, a limiting groove is recessed on the side wall of the connecting hole, and a limiting block is provided on the motor. The limiting block is limited in the limiting groove to drive the transmission plate to rotate.

[0011] Optionally, the first slide rail is located in the direction of the rotation radius of the transmission plate.

[0012] Compared to existing technologies, the visual adjustment mechanism in this invention uses a transmission plate, connecting rod, and bracket to work together. The first lens is fixed on the bracket and moves with the bracket. When the transmission plate rotates, the bracket can slide on the first slide rail to change the shooting position of the first lens. This is simple and convenient, and does not require disassembly or replacement of the lens. Users can control the shooting position of the first lens according to their needs.

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0024] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. The accompanying drawings of embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left, the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the rear, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0025] This utility model embodiment provides a visual adjustment mechanism, combined with Figure 1-5 As shown, the device includes a base 1, a transmission plate 2, a connecting rod 3, a bracket 4, and a first lens 42. The two ends of the connecting rod 3 are rotatably connected to the transmission plate 2 and the bracket 4, respectively. The base 1 is provided with a first slide rail 11, and the bracket 4 is slidably connected to the first slide rail 11. The first lens 42 and the bracket 4 are fixedly connected. When the transmission plate 2 is rotated, the connecting rod 3 drives the bracket 4 to move on the first slide rail 11 to change the shooting position of the first lens 42.

[0026] like Figure 1-3As shown, in this embodiment, the transmission plate 2 is centrally symmetrical. When the transmission plate 2 is rotated in the forward direction, one end of the connecting rod 3 rotates with the transmission plate 2, and the other end of the connecting rod 3 drives the bracket 4 to move. The bracket 4 is limited on the first slide rail 11 and slides along the first slide rail 11 closer to the transmission plate 2. When the transmission plate 2 is rotated in the reverse direction, one end of the connecting rod 3 rotates with the transmission plate 2, and the other end of the connecting rod 3 drives the bracket 4 to move. The bracket 4 is limited on the first slide rail 11 and slides along the first slide rail 11 away from the transmission plate 2. Forward rotation is either clockwise or counterclockwise rotation, and reverse rotation is rotation in the opposite direction to forward rotation. It is worth noting that the transmission plate 2 does not rotate 360 ​​degrees.

[0027] Both the connecting rod 3 and the transmission plate 2 are equipped with weight reduction grooves, which are used to reduce weight and improve transmission performance.

[0028] Compared with the prior art, the visual adjustment mechanism in this utility model, through the cooperation of transmission plate 2, connecting rod 3 and bracket 4, the first lens 42 is fixed on the bracket 4 and moves together with the bracket 4, so that when the transmission plate 2 rotates, the bracket 4 can slide on the first slide rail 11 to change the shooting position of the first lens 42. It is simple and convenient, and does not require disassembly or replacement of the lens. Users can control the shooting position of the first lens 42 according to their needs.

[0029] Optionally, a connecting piece 5 is connected to the bracket 4, and a second lens 51 is fixedly connected to the connecting piece 5. The connecting piece 5 slides together with the bracket 4 to change the shooting position of the second lens 51.

[0030] like Figure 2 As shown, in this embodiment, the connecting piece 5 is L-shaped, one end of the sidewall of the connecting piece 5 is parallel to the first slide rail 11, the connecting piece 5 is connected to the sidewall of the bracket 4, and is limited to the movement trajectory of the connecting rod 3.

[0031] Optionally, the transmission plate 2 includes a connecting part 21 and a clearance part 22. The clearance part 22 is located between two adjacent connecting parts 21. One end of the connecting rod 3 is rotatably connected to the connecting part 21. When the transmission plate 2 is rotated so that the bracket 4 is close to the transmission plate 2, the clearance part 22 is used to avoid the second lens 51.

[0032] like Figure 4 As shown, in this embodiment, there are three connecting rods 3, three supports 4, and three connecting pieces 5. The transmission plate 2 is approximately triangular, the connecting part 21 is the three corners of the triangle, and the clearance part 22 is the three sides of the triangle that are concave inward. When the transmission plate 2 rotates, the three connecting rods 3 simultaneously drive the three supports 4 to slide together.

[0033] Optionally, the first lens 42 is located at the end of the bracket 4 away from the transmission plate 2, the connecting piece 5 is connected to the end of the bracket 4 near the transmission plate 2, and the second lens 51 is located at the end of the connecting piece 5 near the transmission plate 2.

[0034] like Figure 2 As shown, in this embodiment, there are three first lenses 42 and three second lenses 51. The lines connecting the three first lenses 42 form an equilateral triangle, and the lines connecting the three second lenses 51 also form an equilateral triangle. The side length of the equilateral triangle formed by the first lenses 42 is greater than the side length of the equilateral triangle formed by the second lenses 51. When the transmission plate 2 is rotated, the first lenses 42 and the second lenses 51 will simultaneously move closer to or further away from the transmission plate 2, at which point the side lengths of the two equilateral triangles will simultaneously decrease or increase.

[0035] The first lens 42 and the second lens 51 work together to locate the position of the object being photographed through the shooting range and program algorithms. Taking the flange assembly process as an example, in the production and assembly of many large and heavy equipment, flanges need to be assembled onto corresponding mounting bases. Manual assembly is not only laborious, but also difficult to control the assembly angle between workpieces. At this time, the first lens 42 and the second lens 51 work together to photograph the mounting surfaces of the flange and the mounting base, thereby locating the positions of the circular mounting holes on the two mounting surfaces. The position of the flange is adjusted by the lifting claws, so that the two mounting holes are aligned and precise docking is achieved. If the flange model or the size of the circular mounting holes changes, the side length of the equilateral triangle formed by the first lens 42 and the second lens 51 can be changed by rotating the transmission plate 2 to adapt to flanges of different sizes.

[0036] Optionally, a first slide block 41 is connected to the bracket 4, and the first slide block 41 is slidably connected to the first slide rail 11 so that the bracket 4 slides relative to the first slide rail 11.

[0037] like Figure 3 As shown, in this embodiment, the bracket 4 is in the shape of a straight rod, and both ends of the straight rod are connected to the first slide block 41. One end of the connecting rod 3 is rotatably connected to the middle position of the bracket 4, thereby driving the bracket 4 to move more stably.

[0038] Optionally, a third lens 12 is connected to the bottom of the base 1, and a second slide rail 13 is provided at the bottom of the base 1. The third lens 12 is connected to a second slide block 14. The second slide rail 13 and the second slide block 14 are slidably connected so that the third lens 12 slides on the second slide rail 13 to change the shooting position.

[0039] like Figure 1As shown, in this embodiment, there are two third lenses 12, both of which shoot downwards. When the workpiece enters the assembly area, the third lens 12 scans the workpiece and calculates the suitable force point of the workpiece by comparing the feature points in the image, so as to cooperate with the claw to grasp the force point.

[0040] Optionally, a connecting assembly is coaxially connected to the transmission plate 2. The connecting assembly includes a bearing seat 6 and a motor seat 7 connected to each other. The bearing seat 6 contains a bearing 61, and the motor seat 7 is connected to a motor. The motor is coaxially connected to the transmission plate 2 to drive the transmission plate 2 to rotate.

[0041] like Figure 5 As shown, in this embodiment, the rotation angle of the transmission plate 2 can be more precisely controlled by controlling the rotation of the transmission plate 2 by means of a motor. There are two bearings 61, and a bearing bushing 62 connects the two bearings 61. The two bearings 61 cooperate to reduce the coefficient of friction and ensure rotational accuracy.

[0042] like Figure 5 As shown, optionally, the transmission plate 2 has a connecting hole 23 at its center, and a limiting groove 24 is recessed on the side wall of the connecting hole 23. The motor has a limiting block, which is limited in the limiting groove 24 to drive the transmission plate 2 to rotate.

[0043] Optionally, the first slide rail 11 is located in the direction of the rotation radius of the transmission plate 2.

[0044] like Figure 2 and 3 As shown, in this embodiment, the first slide rail 11 is set in the rotation radius direction of the transmission plate 2, which can improve the transmission effect between the transmission plate 2, the connecting rod 3, and the bracket 4, and make the bracket 4 slide more smoothly on the first slide rail 11.

[0045] Another embodiment of this utility model provides an automated device, including the vision adjustment mechanism described above.

[0046] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
