[0002] Existing VCM coils are characterized by their simple structure and small size. Currently, the appearance of VCM coils is inspected using a manual microscope. However, manual microscope inspection has significant drawbacks: First, while employees can clearly identify defects under a microscope, prolonged operation can easily cause visual fatigue, visual inertia, and visual impairment. Second, although the microscope can be adjusted to any angle, repeated contact between the hands and the VCM coil can easily cause hidden damage. Third, it heavily relies on the individual employee's ability and stability, requiring a high level of proficiency, resulting in poor quality consistency, difficulty in manual operation, and high costs, significantly impacting mold production efficiency and costs.

[0027] Please combine Figure 1 and Figure 3 As shown, the appearance inspection device 300 of this utility model includes multiple CCD cameras and a back inspection bracket 350. Each of the multiple CCD cameras is arranged in a clockwise order according to multiple rotating working positions on the turntable 110, and each CCD camera is aligned with a rotating fixture 210 provided on the corresponding rotating working position. The multiple CCD cameras include at least a front inspection CCD camera group 310, a side inspection CCD camera 320, an edge inspection CCD camera 330, and a back inspection CCD camera 340 arranged in a clockwise order according to the multiple rotating working positions on the turntable 110. The front inspection CCD camera group 310 includes at least one front overall inspection CCD camera 311 and multiple front partial inspection CCD cameras 312.
[0028] In the front-facing inspection CCD camera group 310 of this utility model, the camera lens of each CCD camera is parallel to the corresponding rotating working position, and the camera lens of each CCD camera is placed above the VCM coil to be inspected on the corresponding rotating fixture 210.
[0029] Specifically, the camera lens of the front-side overall inspection CCD camera 311 of this invention is parallel to the corresponding rotating working position, and the camera lens of the front-side overall inspection CCD camera 311 is positioned above the VCM coil to be inspected on the corresponding rotating fixture 210, so as to perform overall inspection of the front side of the VCM coil to be inspected. In this embodiment, the camera lens of the front-side overall inspection CCD camera 311 is arranged parallel to the second rotating working position 2 above; the front-side overall inspection CCD camera 311 performs overall inspection of the front side of the VCM coil to be inspected on the second rotating device 200B.
[0030] In this invention, the camera lens of each of the multiple front-side partial detection CCD cameras 312 is parallel to the corresponding rotating working position, and the camera lens of each of the multiple front-side partial detection CCD cameras 312 is placed above the VCM coil to be detected on the corresponding rotating fixture 210, so as to detect the front part of the VCM coil to be detected. In this embodiment, the plurality of front-side partial detection CCD cameras 312 include a first front-side partial detection CCD camera 312A, a second front-side partial detection CCD camera 312B, and a third front-side partial detection CCD camera 312C. The camera lenses of the first front-side partial detection CCD camera 312A, the second front-side partial detection CCD camera 312B, and the third front-side partial detection CCD camera 312C are respectively arranged parallel above the third rotating working position 3, the fourth rotating working position 4, and the fifth rotating working position 5. The first front-side partial detection CCD camera 312A, the second front-side partial detection CCD camera 312B, and the third front-side partial detection CCD camera 312C perform partial detection on the front side of the VCM coil to be detected on the third rotating device 200C, the fourth rotating device 200D, and the fifth rotating device 200E.
[0031] The camera lens of the side-detection CCD camera 320 of this invention is set at an acute angle to the corresponding rotating work position, and the camera lens of the side-detection CCD camera 320 is positioned above the VCM coil to be detected on the corresponding rotating fixture 210, so that the camera lens of the side-detection CCD camera 320 is tilted above the VCM coil to be detected on the corresponding rotating fixture 210, so as to detect the side of the VCM coil to be detected. In this embodiment, the camera lens of the side-detection CCD camera 320 is tilted above the sixth rotating work position 6; the side-detection CCD camera 320 detects the contour edge of the VCM coil to be detected on the sixth rotating device 200F.
[0032] The edge detection CCD camera 330 of this invention has its camera lens parallel to the corresponding rotating work position, and the camera lens is positioned above the VCM coil to be detected on the corresponding rotating fixture 210 to detect the contour edge of the VCM coil. In this embodiment, the camera lens of the edge detection CCD camera 330 is positioned parallel to the seventh rotating work position 7 above it; the edge detection CCD camera 330 detects the contour edge of the VCM coil to be detected on the seventh rotating device 200G.
[0033] The models of the front overall detection CCD camera 311, the multiple front partial detection CCD cameras 312, and the edge detection CCD camera 330 of this utility model are different, and the height of the camera lens of each of the front overall detection CCD camera 311, the multiple front partial detection CCD cameras 312, and the edge detection CCD camera 330 relative to the VCM coil to be detected is also different, so as to obtain different focal lengths.
[0034] Furthermore, each of the front-side overall detection CCD camera 311, the multiple front-side partial detection CCD cameras 312, and the edge detection CCD camera 330 of this utility model can switch detection functions according to the detection requirements of the VCM coil. Since the terminals of the VCM coil are on the front side, and there are relatively strict requirements for the terminals, the inner ring, and the edge, there are many cameras that can perform overall or partial detection on the front side of the VCM coil.
[0035] The reverse detection CCD camera 340 and the back detection bracket 350 of this utility model are placed on the outer side of the turntable 110, and the camera lens of the reverse detection CCD camera 340 is parallel to the corresponding reverse detection work position. The reverse detection work position is set on the back detection bracket 350, and the back detection bracket 350 is placed above the camera lens of the reverse detection CCD camera 340. When the VCM coil to be detected is placed on the back detection bracket 350, the reverse detection CCD camera 340 detects the reverse side of the VCM coil to be detected.
[0036] Please combine Figure 1 , Figure 3 and Figure 4 As shown, the moving mechanism 400 of this utility model includes a suction nozzle 430 connected to a vertical moving cylinder 410 and a horizontal moving cylinder 420. The vertical moving cylinder 410 and the horizontal moving cylinder 420 are connected to a VCM coil appearance detection controller. The vertical moving cylinder 410 and the horizontal moving cylinder 420 are located on the outer side of the turntable 110.
[0037] Before moving, the suction nozzle 430 is located on the turntable 110 at a corresponding rotating work position arranged clockwise, following the rotating work position corresponding to the camera lens of the edge detection CCD camera 330. Before moving, the suction nozzle 430 is positioned above the VCM coil to be tested on the corresponding rotating fixture 210 to pick up the VCM coil. After moving, the suction nozzle 430 is positioned above the VCM coil to be tested on the back detection bracket 350 to pick up the VCM coil and transfer it to the reverse detection work position for reverse detection of the VCM coil. In this embodiment, the camera lens of the reverse detection CCD camera 340 is arranged parallel to the reverse detection work position on the back detection bracket 350. The suction nozzle 430 is located above the eighth rotating work position 8 before it moves. With the cooperation of the up and down moving cylinder 410, it picks up the VCM coil to be tested on the eighth rotating device 200H. The suction nozzle 430 picks up the VCM coil to be tested and moves it to the reverse detection work position on the back detection bracket 350 for inspection under the drive of the left and right moving cylinder 420, so as to inspect the reverse side of the VCM coil to be tested.
[0038] In this embodiment, when the fully automatic appearance inspection equipment for VCM coils is working, the first rotating work station 1 is the loading station. After the VCM coil to be inspected is loaded onto the rotating fixture 210 of the corresponding first rotating device 200A, the appearance inspection sequence of the fully automatic appearance inspection equipment for VCM coils of this utility model is as follows: the turntable 110 rotates clockwise, allowing the loaded VCM coil to be inspected to be inspected in sequence by the front overall inspection CCD camera 311, the first front partial inspection CCD camera 312A, the second front partial inspection CCD camera 312B, the third front partial inspection CCD camera 312C, the side inspection CCD camera 320, the edge inspection CCD camera 330, and the back inspection CCD camera 340.
[0039] In this specific embodiment, the frontal overall inspection CCD camera 311 performs frontal appearance inspection on one side of the terminal of the VCM coil to be inspected, which is positioned at the second rotating working position 2 of the turntable 110. After the rotating fixture 210 rotates another 180°, the frontal appearance inspection is performed on the other side of the terminal of the VCM coil to be inspected. The first frontal partial inspection CCD camera 312A performs frontal appearance inspection on the periphery of the terminal of the VCM coil to be inspected, which is positioned at the third rotating working position 3 of the turntable 110. After the rotating fixture 210 rotates another 180°, the frontal appearance inspection is performed on the periphery of the terminal of the VCM coil to be inspected. The second frontal partial inspection CCD camera 312B performs frontal appearance inspection on the inner ring point of the VCM coil to be inspected, which is positioned at the fourth rotating working position 4 of the turntable 110. The third frontal partial inspection CCD camera 312C performs frontal appearance inspection on the terminal of the VCM coil to be inspected, which is positioned at the fifth rotating working position 5 of the turntable 110. The inner ring of the VCM coil to be tested undergoes a frontal appearance inspection. The side inspection CCD camera 320 inspects the side of one terminal of the VCM coil to be tested, which is positioned at the sixth rotating work position 6 of the turntable 110. After the rotating fixture 210 rotates another 180°, the side of the other terminal of the VCM coil to be tested is inspected. The edge inspection CCD camera 330 inspects the edge of the VCM coil to be tested, which is positioned at the seventh rotating work position 7 of the turntable 110. After the rotating fixture 210 rotates another 180°, the edge of the VCM coil to be tested is inspected again. The moving mechanism 400 moves the VCM coil to be tested, positioned at the eighth rotating work position 8 of the turntable 110, to the reverse inspection work position on the back inspection bracket 350. The reverse inspection CCD camera 340 then inspects the bottom surface of the VCM coil to be tested at the reverse inspection work position. VCM coils that pass inspection are unloaded onto a tray, while VCM coils that fail inspection are classified according to their defect type and placed in a defective product box.
