Abstract
Description
Technical Field

[0027] Please refer to Figure 1 , to solve the problem of low detection rate of surface defects of inductor a, the present utility model proposes an inductor detection device 1000, including:
[0028] A frame 1, a loading device, and a vision detection device. The loading device includes a turntable 21 and a transparent loading ring 22. The turntable 21 is rotatably arranged on the frame 1, and the direction of rotation of the turntable 21 is defined as the first direction; the transparent loading ring 22 is arranged on the outer peripheral edge of the turntable 21, and the transparent loading ring 22 is used to load the inductor a; the vision detection device includes at least six detection cameras 31 and a fill light 32 with the same orientation as each detection camera 31. Each detection camera 31 and each fill light 32 are arranged on the frame 1; two detection cameras 31 are respectively located above and below the transparent loading ring 22 and are respectively used to photograph the upper and lower surfaces of the inductor a; two detection cameras 31 are respectively located outside and inside the transparent loading ring 22 and are respectively used to photograph the left and right side surfaces of the inductor a; two detection cameras 31 are respectively located in front of and behind the transparent loading ring 22 along the first direction and are respectively used to photograph the front and rear side surfaces of the inductor a. In the technical solution of the present utility model, surface defect detection is sequentially performed on the upper, lower, left, right, front, and rear six surfaces of the inductor a by at least six detection cameras 31, and each detection camera 31 is equipped with a fill light 32 with the same orientation as the detection camera 31, so that each fill light 32 can directly irradiate on the corresponding surface of the inductor a, thereby improving the detection rate of surface defects of the inductor a.
[0029] In one embodiment, the number of both the detection cameras 31 and the supplementary light lamps 32 is six. The six detection cameras 31 and the six supplementary light lamps 32 can achieve defect detection on the upper, lower, left, right, front, and rear six faces of the inductor a, and at the same time can reduce the production cost of the inductor detection device 1000. Therefore, it is preferred that the number of both the detection cameras 31 and the supplementary light lamps 32 is six.
[0030] In one embodiment, the inductor detection device 1000 further includes a feeding device. The feeding device includes a feeding conveyor belt 41, and the feeding conveyor belt 41 is arranged on the frame 1; the feeding device further has a feeding station 4a, and the feeding station 4a is located on the transparent carrier ring 22 and is arranged near the end of the feeding conveyor belt 41. The feeding conveyor belt 41 conveys the inductor a to the feeding station 4a. When the inductor a reaches the feeding station 4a, the inductor a will rotate following the transparent carrier ring 22, and the six detection cameras 31 respectively perform surface defect detection on the upper, lower, left, right, front, and rear six faces of the inductor a in sequence, realizing the feeding automation of the inductor a detection.
[0031] In one embodiment, the feeding device further includes two positioning plates 42, and both the two positioning plates 42 are arranged on the frame 1 and are located above the feeding conveyor belt 41. When the feeding conveyor belt 41 conveys the inductor a, the two positioning plates 42 cooperate to limit the inductor a to adjust the inductor a to a suitable angle for the six detection cameras 31 to detect. In this way, the inductor a can be adjusted to the best detection angle, thereby improving the detection rate of the surface defects of the inductor a.
[0032] In one embodiment, the inductor detection device 1000 further includes a discharging device. The discharging device is arranged on the frame 1; the discharging device has a discharging station 5a, and the discharging station 5a is located on the transparent carrier ring 22 and is in front of each detection camera 31 along the first direction. After the six faces of the inductor a are all detected, the inductor a can rotate following the transparent carrier ring 22 to the discharging station 5a to realize the automatic discharging of the inductor a and avoid the repeated testing of the inductor a.
[0033] In one embodiment, the discharging device includes a discharging conveyor belt 51, and the discharging conveyor belt 51 is arranged on the frame 1, and the discharging station 5a is arranged near the front end of the discharging conveyor belt 51. The discharging conveyor belt 51 can automatically send the detected inductor a away from the transparent carrier ring 22 to avoid the inductor a being blocked at the discharging station 5a.
[0034] In one embodiment, the inductor detection device 1000 further includes a screening device 6. The screening device 6 is arranged on the frame 1 and is located at the discharging station 5a; the screening device 6 is electrically connected to each detection camera 31. The screening device 6 is electrically connected to each detection camera 31 through an industrial control computer. When the detection camera 31 detects an unqualified inductor a, the industrial control computer controls the screening device 6 to screen out the unqualified inductor a from the discharging station 5a, realizing automatic screening and improving the detection efficiency of the inductor a.
[0035] The screening device 6 can be a pushing mechanism to push the unqualified inductor a out of the transparent carrier ring 22, or it can be a manipulator to pick up the unqualified inductor a from the transparent carrier ring 22. In one embodiment, the screening device 6 is a manipulator, and the manipulator is used to remove the unqualified products from the inductor a.
[0036] In one embodiment, the blanking device further includes a defective product collection box 52. The defective product collection box 52 is arranged on the frame 1 and is used to hold the unqualified products in the inductor a removed by the manipulator, so as to place the unqualified inductor a and the qualified inductor a separately, which is convenient for the inspectors to use.
[0037] In one embodiment, the blanking device further includes a high-quality product collection box 53. The high-quality product collection box 53 is arranged on the frame 1, and the opening of the high-quality product collection box 53 is located at the end of the blanking conveyor belt 51. The manipulator removes the unqualified inductor a in the blanking station 5a into the defective product collection box 52, and the remaining qualified inductors a are conveyed by the blanking conveyor belt 51 into the high-quality product collection box 53 to complete the automatic collection of the qualified inductors a.
[0038] Since the inspection cameras 31 for inspecting the front and back surfaces of the inductor a will hinder the rotation of the inductor a following the transparent carrier ring 22 when they are facing the front and back surfaces of the inductor a, the inspection cameras 31 for inspecting the front and back surfaces of the inductor a cannot be directly facing the front and back surfaces of the inductor a. Because of this, the inspection cameras 31 for inspecting the front and back surfaces of the inductor a cannot be adjusted to the best inspection angle, resulting in the defect detection rate of the front and back surfaces of the inductor a being much lower than that of the other four surfaces. In one embodiment, the vision inspection device further includes two prisms 33, and the two prisms 33 are respectively arranged at the front ends of the two inspection cameras 31 located in front of and behind the transparent carrier ring 22 along the first direction. The two prisms 33 can adjust the collected light of the two inspection cameras 31 in the front and back directions, so that the images of the front and back surfaces of the inductor a collected by the two inspection cameras 31 are at the best inspection angle, thereby improving the defect detection rate of the front and back surfaces of the inductor a.
[0039] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
