Technical Field

[0001] This utility model relates to the field of appearance inspection technology, specifically to an appearance inspection structure for irregularly shaped shielding covers. Background Technology

[0002] After the mobile phone shielding is cut and bent, it usually needs to undergo visual inspection to determine whether it meets the quality standards in order to ensure its quality.

[0003] However, since some shielding covers have irregular structures, conventional testing equipment usually adopts a fixed viewing angle for shooting, which is difficult to adapt to the complex geometry of irregular shielding covers, especially at the edges, bends or special structural areas, which can easily lead to blind spots in the detection, resulting in a limited detection angle and the risk of missed detection.

Because some shields have irregular structures, conventional inspection equipment usually adopts a fixed-view shooting method, which is difficult to adapt to the complex geometry of irregularly shaped shields. Especially at the edges, bends, or special structural areas, blind spots are prone to occur, resulting in a limited inspection view.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An appearance inspection structure for irregularly shaped shielding covers, comprising: The machine tool is equipped with an indexing turntable on its top. A blanking assembly for removing and repositioning workpieces from an indexing turntable, the blanking assembly being disposed on one side of the indexing turntable; An image acquisition component is located on one side of the indexing turntable and mounted on the machine base; A gripping structure for grasping workpieces during unloading and bringing them near an image acquisition component for imaging.

[0006] The beneficial effects of this utility model are: 1) The unloading component precisely removes the workpiece from the indexing turntable and adjusts its position, providing accurate positioning for the subsequent gripping structure. The gripping structure uses clamping components to firmly hold the workpiece, combined with the first servo motor driving the connecting arm to rotate, and the lifting component moving up and down, ensuring that the irregularly shaped shielding cover can be accurately positioned within the lens range of the image acquisition component. Then, the second servo motor drives the clamping components and the shielding cover to rotate at multiple angles. The image acquisition component can fully capture the appearance features of the shielding cover, reducing the risk of missed detection and improving detection accuracy and reliability.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the image acquisition component includes at least three CCD camera modules, wherein the three CCD camera modules are arranged in a triangular shape on the machine platform.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by setting at least three CCD camera modules arranged in a triangular shape, and with the workpiece located at the center of the CCD camera modules, as the workpiece rotates, the three CCD camera modules simultaneously capture images of the workpiece from various angles, which can speed up the completion of comprehensive imaging of the workpiece and improve inspection efficiency.

[0010] Furthermore, the feeding assembly includes a support plate, a first cylinder, a slide rail, a slider, a vertical plate, a third servo motor, and a picking rod.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the first cylinder drives the slider and the vertical plate to slide along the slide rail path, so that the picking rod moves in the direction of approaching the workpiece. After the picking rod is inserted into the workpiece, the third servo motor drives the picking rod and the workpiece to rotate 90 degrees, so that the workpiece faces upward and is adjusted to the best posture for easy gripping by the gripping structure.

[0013] Furthermore, the lifting assembly is configured as a second cylinder.

[0014] Furthermore, the clamping component is configured as a cylinder gripper. Attached Figure Description

[0017] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0018] After the mobile phone shielding is cut and bent, it usually needs to undergo visual inspection to determine whether it meets the quality standards in order to ensure its quality.

[0019] However, since some shielding covers have irregular shapes, conventional testing equipment usually adopts a fixed-view shooting method, which is difficult to adapt to the complex geometry of irregular shielding covers. Especially at the edges, bends or special structural areas, blind spots are likely to occur, resulting in a limited testing view and a risk of missed detection. In response, the inventor of this utility model proposed an appearance inspection structure for irregular shielding covers to solve the above problems.

The feeding assembly 40 is located on one side of the indexing turntable 101. Image acquisition component 20 is located on one side of indexing turntable 101 and is mounted on machine base 10; A gripping structure 30 is used to grip the workpiece being unloaded and bring it near the image acquisition component 20 for imaging. The gripping structure 30 includes a base 301, a first servo motor 302, a connecting arm 304, a head 305, a second servo motor 303, a lifting component 306, and a clamping component 307. The base 301 is fixed on the machine platform 10, the first servo motor 302 is fixed on the base 301, one end of the connecting arm 304 is fixed on the drive end of the first servo motor 302, the head 305 is located on the other end of the connecting arm 304, the lifting component 306 is located on one side of the head 305, the second servo motor 303 is fixed on the lifting end of the lifting component 306, and the clamping component 307 is located on the drive end of the second servo motor 303. The unloading component 40 precisely removes the workpiece from the indexing turntable 101 and adjusts its position, providing accurate positioning for the subsequent gripping structure 30. The gripping structure 30 uses the clamping component 307 to firmly clamp the workpiece, combined with the first servo motor 302 driving the connecting arm 304 to rotate, and the lifting component 306 moving up and down, to ensure that the irregular shielding cover can be accurately positioned within the lens range of the image acquisition component 20. Then, the second servo motor 303 drives the clamping component 307 and the shielding cover to rotate at multiple angles. The image acquisition component 20 can fully capture the appearance features of the shielding cover, reduce the risk of missed detection, and improve detection accuracy and reliability.

[0021] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the image acquisition component 20 includes at least three CCD camera modules, which are arranged in a triangular shape on the machine base 10.

The first cylinder 402 drives the slider 404 and the vertical plate 405 to slide along the slide rail 403, causing the picking rod 407 to move in the direction of approaching the workpiece. When the picking rod 407 is inserted into the workpiece, the third servo motor 406 drives the picking rod 407 and the workpiece to rotate.
