Description

Technical Field

[0001] This utility model relates to a visual inspection device, specifically an online visual inspection device for micro electronic components. Background Technology

[0002] When manufacturing tiny electronic components, visual inspection equipment is required for their inspection. Visual inspection equipment is an industrial device that uses industrial cameras, image processing systems, and intelligent algorithms to automate inspections, replacing the human eye. Its core working principle is to acquire images of objects through optical imaging, then analyze image features (such as size, color, and defects) using algorithms, and finally output the inspection results and control the actuators. It is mainly used to detect product appearance defects, dimensional deviations, and other problems, and automatically reject unqualified products.

[0003] Existing online visual inspection equipment for microelectronic components has a complex structure and unreasonable design. The position of the top visual inspection device is inconvenient to adjust, and its height and angle cannot be well adjusted, preventing inspection from different heights and angles. Furthermore, the visual inspection equipment cannot rotate the product under inspection during operation, forcing it to monitor from only a specific angle, which easily leads to missed detections. Therefore, the inventors have improved the structure of the online visual inspection equipment for microelectronic components. Utility Model Content

The device includes a worktable 1, a protective cover 2 and a shelf 3 fixed on the worktable 1. The shelf 3 is located on one side of the protective cover 2, and a slide rail 4 is fixed on the upper surface of the shelf 3. In this embodiment, two slide rails 4 are provided and are arranged in parallel. In addition, an observation window 8 is provided above the worktable 1 and is fixed to the end of the protective cover 2 near the shelf 3.

[0024] Please see Figure 2 A feeding plate 5 and a rotating device 6 located below the feeding plate 5 are provided on the slide rail 4. The two ends of the feeding plate 5 are respectively provided on the two slide rails 4, so that the feeding plate 5 can slide smoothly on the two slide rails 4. A vision inspection device 7 is provided above the rotating device 6, wherein the vision inspection device 7 is fixed inside the protective cover 2.

[0025] Please see Figure 3The rotating device 6 includes a support base 61 and a first cylinder 62 fixed on the support base 61. The support base 61 is fixed to the upper surface of the platform 3. A lifting platform 63 is connected to the output end of the first cylinder 62. The lifting platform 63 has a hollow cavity structure and is provided with several heat dissipation holes 631 communicating with its cavity. A motor 64 is provided on the lifting platform 63 and is fixed in the cavity of the lifting platform 63. The several heat dissipation holes 631 can assist in the heat dissipation of the motor 64 and prevent the motor 64 from overheating. In this embodiment, the motor 64 will not work for a long time, but only for a short time. Therefore, overheating will not occur. The output end of the motor 64 is provided with a platform 65 and a vacuum suction cup 66 located above the platform 65. The platform 65 is fixedly connected to the output end of the motor 64 and is located above the lifting platform 63. The vacuum suction cup 66 is installed on the upper surface of the platform 65 and is located below the loading plate 5. When the vacuum suction cup 66 contacts the lower surface of the loading plate 5, it can adsorb the loading plate 5. In this embodiment, the vacuum suction cup 66 is an electric vacuum suction cup, and its structure is existing technology, which will not be described in detail here. Except for the suction cup, all other structures are set on the platform 65.

[0026] Please see Figure 4 The visual inspection device 7 includes a second cylinder 71 and a lifting handle 72 connected to the output end of the second cylinder 71. The second cylinder 71 is fixed inside the protective cover 2 and is vertically arranged. A flip handle 73 is fixed at the end of the lifting handle 72 away from the second cylinder 71. A detection camera 74 is movably connected at the end of the flip handle 73 away from the lifting handle 72. The detection camera 74 can be damped and rotated to adjust its detection angle so as to adapt to the detection of different products. The structure of the detection camera 74 is existing technology and will not be described in detail here.

[0027] Working principle: Please refer to the following again. Figures 1 to 4In this invention, the microelectronic component to be inspected is placed on the loading plate 5, which moves along the two slide rails 4 and gradually moves above the rotating device 6, falling into the detection range of the visual inspection device 7. At this point, the loading plate 5 stops moving, and the first cylinder 62 is driven to move the lifting platform 63, motor 64, platform 65, and vacuum suction cup 66 upward, so that the vacuum suction cup 66 contacts the lower end surface of the loading plate 5, adsorbing the loading plate 5 and lifting it upward, causing the loading plate 5 to detach from the two slide rails 4. Then, the detection camera is adjusted according to the size and shape characteristics of the microelectronic component. The head 74, through the second cylinder 71, can adjust the height of the detection camera 74. The angle of the detection camera 74 can be adjusted by flipping it on the flip handle 73, so that the detection camera 74 can be moved to the most suitable position for visual inspection. At the same time as visual inspection, the drive motor 64 drives the vacuum suction cup 66 and the loading plate 5 to rotate 360° at a constant speed, so that the detection camera 74 can inspect various parts of the micro electronic components. After the inspection is completed, the first cylinder 62 drives the suction cup 66 to descend, and the loading plate 5 can be placed on the slide rail 4. Then the loading plate 5 continues to move forward and outputs the micro electronic components.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
