Description

Technical Field

[0001] This utility model relates to the field of industrial automation testing equipment technology, specifically to a product positioning carrier for automated visual inspection. Background Technology

[0002] Automated visual inspection technology, as a core supporting technology in the field of industrial automation, achieves rapid and accurate detection of parameters such as appearance defects, dimensional deviations, and surface quality of industrial products through optical imaging, image processing, and pattern recognition. It typically uses high-resolution cameras to capture product images and combines technologies such as 3D line lasers and coaxial light sources to identify micron-level defects. It is widely used in fields such as electronics manufacturing, automobile production, food processing, and pharmaceuticals. In the process of automated visual inspection, positioning carriers are required to locate the product so that the camera can accurately capture images of the product.

[0003] However, when using traditional positioning carriers, the product is usually placed on the carrier, and the product is manually moved to the center position according to the positioning mark at the center. The positioning operation relies on the work experience and visual observation of the staff, which is slow and prone to positioning errors, causing a lot of inconvenience to visual inspection. Utility Model Content

[0004] The purpose of this invention is to provide a product positioning carrier for automated visual inspection, in order to solve the problems in the existing technology that rely on the work experience and visual observation of workers, resulting in slow positioning speed and easy positioning errors, which bring many inconveniences to visual inspection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a product positioning carrier for automated visual inspection, comprising:

[0006] The vehicle mechanism and the operating mechanism mounted on the bottom of the vehicle mechanism, and the positioning mechanism mounted on the top of the vehicle mechanism;

[0007] The vehicle mechanism includes a loading plate, and the top of the loading plate has a movable groove;

[0008] The operating mechanism includes a bidirectional lead screw rotatably mounted on the bottom of the carrier plate;

[0009] The positioning mechanism includes two movable blocks threaded onto the bidirectional lead screw. The movable blocks extend out of the movable groove. A second positioning frame is fixedly installed on the top of the movable blocks. Two first positioning frames are slidably installed between the second positioning frames. A track frame is fixedly installed on one side of the first positioning frame. A track groove is opened on the surface of the track frame. A sliding pile inserted into the track groove is fixedly installed on the top of the second positioning frame.

[0010] Furthermore, support frames are fixedly installed on both sides of the loading plate, and mounting holes are provided on the support frames.

[0011] Furthermore, a shaft frame is fixedly installed at the bottom of the loading plate, and the two ends of the bidirectional lead screw are rotatably connected to the shaft frame.

[0012] Furthermore, the movable block has a threaded hole inside, which meshes with the bidirectional lead screw.

[0013] Furthermore, a turntable is fixedly installed at the front end of the bidirectional lead screw, and a handle is rotatably installed at the front end of the turntable.

[0014] Furthermore, the first positioning frame has a moving slot inside, and the second positioning frame passes through the moving slot.

[0015] Furthermore, a first protective pad is adhered to the inner wall of the first positioning frame, and a second protective pad is adhered to the inner wall of the second positioning frame.

[0016] Compared with existing technologies, this utility model provides a product positioning carrier for automated visual inspection. Through the cooperation between the operating mechanism and the positioning mechanism, the product can be placed at any position on the carrier plate. By driving the bidirectional lead screw to rotate, two second positioning frames can be driven to move closer together. Through the sliding action of the sliding pile along the track groove, the inclined track groove can cause the sliding pile to exert a squeezing effect on the track frame, which can force the two first positioning frames to move closer together synchronously. This can continuously reduce the central area enclosed by the first and second positioning frames, and accurately push the product to the center position. Without relying on experience judgment and visual observation, the product can be positioned in the central visual inspection area relatively quickly, enabling the visual inspection equipment to accurately acquire the image of the product. This can reduce the situation that is prone to positioning errors and bring more convenience to visual inspection work. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] Example 1:

[0028] This utility model provides a product positioning carrier for automated visual inspection, comprising:

[0029] The vehicle mechanism 1, the operating mechanism 2 mounted on the bottom of the vehicle mechanism 1, and the positioning mechanism 3 mounted on the top of the vehicle mechanism 1;

[0030] The vehicle mechanism 1 includes a cargo plate 11, and a movable groove 12 is provided on the top of the cargo plate 11;

[0031] The operating mechanism 2 includes a bidirectional lead screw 22 rotatably mounted on the bottom of the loading plate 11;

[0032] The positioning mechanism 3 includes two movable blocks 37 threaded onto a bidirectional lead screw 22. The movable blocks 37 extend into movable grooves 12. A second positioning frame 36 is fixedly installed on the top of the movable blocks 37. Two first positioning frames 31 are slidably installed between the second positioning frames 36. A track frame 32 is fixedly installed on one side of the first positioning frame 31. A track groove 33 is opened on the surface of the track frame 32. A sliding pile 310 inserted into the track groove 33 is fixedly installed on the top of the second positioning frame 36.

[0033] As can be seen from the above, by placing the carrier plate 11 on the visual inspection workbench and fixing it during use, and by placing the product to be inspected at any position on the carrier plate 11, the two moving blocks 37 can be driven to move relative to each other along the movable groove 12 by rotating the bidirectional lead screw 22 through the threaded engagement between the bidirectional lead screw 22 and the moving block 37. At the same time, the moving block 37 is limited by the movable groove 12, so that the moving block 37 will not rotate synchronously with the bidirectional lead screw 22, thus enabling the relative movement of the moving block 37.

[0034] When the moving block 37 moves relative to the other, it can drive the two second positioning frames 36 to move closer to each other. The sliding pile 310 can slide along the track groove 33. Since the track groove 33 is inclined, the sliding pile 310 can exert a squeezing effect on the track frame 32, which can force the two first positioning frames 31 to move closer to each other synchronously. This can make the central area enclosed by the first positioning frames 31 and the second positioning frames 36 continuously shrink, and can accurately push the product to the center position. At the same time, the first positioning frames 31 and the second positioning frames 36 can clamp and fix the product from all sides, so that the product will not shift or shake. Without relying on experience judgment and visual observation, the product can be positioned in the center visual inspection area relatively quickly, so that the visual inspection equipment can accurately acquire the image of the product. This can effectively reduce the situation that is prone to positioning errors, improve accuracy, and bring more convenience to visual inspection work.

[0035] From the appendix Figure 2 It can be seen that support frames 13 are fixedly installed on both sides of the loading plate 11, and mounting holes 14 are provided on the support frames 13.

[0036] As can be seen from the above, by using bolts and mounting holes 14, the support frame 13 can be fixed in a suitable position on the vision inspection platform. The support frame 13 can easily support the carrier plate 11, making the carrier mechanism 1 less prone to shaking and improving the stability effect during product vision inspection.

[0037] For details, please refer to the appendix. Figure 3 As shown, a shaft frame 21 is fixedly installed at the bottom of the loading plate 11, and the two ends of the bidirectional lead screw 22 are rotatably connected to the shaft frame 21.

[0038] As can be seen from the above, the shaft bracket 21 can support the bidirectional lead screw 22, enabling the bidirectional lead screw 22 to rotate stably and preventing the bidirectional lead screw 22 from shaking when rotating.

[0039] For details, please refer to the appendix. Figure 4 As shown, the movable block 37 has a threaded hole 38 inside, which meshes with the bidirectional lead screw 22.

[0040] As can be seen from the above, by passing through the threaded hole 38 with the double-acting screw 22, the threads in the threaded hole 38 can mesh with the threads on the surface of the double-acting screw 22, so that during the rotation of the double-acting screw 22, the moving block 37 can be moved by the meshing of the threads.

[0041] Working principle: The carrier plate 11 is fixed in a position on the vision inspection platform to ensure that it will not shake. By placing the product to be visually inspected at any position on the carrier plate 11, the two-way lead screw 22 is rotated, which drives the two moving blocks 37 to move relative to each other. This can simultaneously drive the two second positioning frames 36 to move relative to each other. During the movement of the second positioning frames 36, the sliding piles 310 can be moved synchronously. As the sliding piles 310 slide along the inclined track groove 33, they can exert a squeezing effect on the track frame 32, which can force the two first positioning frames 31 to move relative to each other and close together. They can also close together synchronously with the second positioning frames 36, so that the central area enclosed by the first positioning frames 31 and the second positioning frames 36 continuously shrinks, which can accurately push the product to the center position. At the same time, the first positioning frames 31 and the second positioning frames 36 can clamp and fix the product from all sides, so that the product will not shift or shake.

[0042] Example 2:

[0043] Reference Appendix Figure 3 As shown, a turntable 23 is fixedly installed at the front end of the bidirectional lead screw 22, and a handle 24 is rotatably installed at the front end of the turntable 23.

[0044] As can be seen from the above, by holding the throttle 24, the turntable 23 can be rotated. The throttle 24 and the turntable 23 are rotatably connected, which allows the throttle 24 to perform corresponding rotational movements. The rotational movement of the turntable 23 can drive the bidirectional lead screw 22 to rotate synchronously, which can easily drive the second positioning frame 36 and the first positioning frame 31 to close and unfold. It can also easily push the product to the center position to achieve rapid positioning.

[0045] Reference Appendix Figure 4 As shown, the first positioning frame 31 has a moving groove 35 inside, and the second positioning frame 36 passes through the moving groove 35.

[0046] As can be seen from the above, when the first positioning frame 31 closes and unfolds, it can slide along the moving groove 35, while not affecting the second positioning frame 36's closing and unfolding movements. This allows the first positioning frame 31 and the second positioning frame 36 to close and unfold synchronously, facilitating the control of the expansion and contraction of the central area space.

[0047] Reference Appendix Figure 4 As shown, the inner wall of the first positioning frame 31 is covered with a first protective pad 34, and the inner wall of the second positioning frame 36 is covered with a second protective pad 39.

[0048] As can be seen from the above, when the product comes into contact with the first positioning frame 31, the first protective pad 34 can adhere to the product surface. When the product comes into contact with the second positioning frame 36, the second protective pad 39 can adhere to the product surface. Both the first protective pad 34 and the second protective pad 39 are made of rubber. When the first positioning frame 31 and the second positioning frame 36 push the product, the product surface can be effectively protected from scratches, avoiding damage to the product and bringing more convenience to the user.

[0049] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
