[0035] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described through the implementation method with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0036] Example 1

[0037] One of the implementation methods of the present application using an optical high-speed automated gear detection device is as follows: Figures 1 to 7 As shown, it includes: a vibration feeder 10, a turntable module, a first visual inspection module 50 and a base plate 80; the vibration feeder 10, the turntable module and the first visual inspection module 50 are all arranged on the base plate 80. Among them, the turntable module includes: a turntable 30, a transfer plate 23, a material plate 20 and a rotating drive member 60.

[0038] The rotary driving member 60 is used to drive the turntable 30 to rotate.

[0039] The material tray 20 is fixed above the transfer tray 23; a plurality of columns 40 are fixed at the bottom of the transfer tray 23, which are suspended above the turntable 30 and fixedly connected to the turntable 30 through the columns 40, so that the material tray 20 rotates synchronously with the turntable 30.

[0040] The material tray 20 is annular and made of transparent material; a plurality of bearing grooves 21 are provided on the outer edge of the material tray 20. The discharge port of the vibrating feeder 10 is located at the outer edge of the material tray 20, and the bearing grooves 21 are used to convey the gears.

[0041] The first visual inspection module 50 includes a first camera 52 and a light emitting unit 51. The light emitting unit 51 and the first camera 52 are arranged on the same axis relative to each other, and are respectively arranged on the inner and outer positions of the material tray 20. The axis passes through the center of the turntable 30. The light emitting unit 51 is used to provide a light source for the first camera 52. The first camera 52 is used to detect the structure and size of the upper and lower sides of the gear.

[0042] The bottom and top of the shooting part of the first camera 52 correspond to the upper and lower positions of the bearing slot 21, respectively, and the bottom and top of the light-emitting unit 51 correspond to the upper and lower positions of the bearing slot 21, respectively. In this way, the light-emitting unit 51 and the first camera 52 cooperate to simultaneously detect the upper and lower parts of the gear on the bearing slot 21. Since the material tray 20 is made of a light-transmitting material, the material tray 20 will not block the light, and the first camera 52 can take pictures and detect the middle part of the gear. In addition, since the main part of the material tray 20 does not have any obstructions in its own radial direction, there is no need to set a clearance position on the edge of the material tray 20 to avoid the column 40, and the bearing slots 21 on the edge of the material tray 20 can be set continuously, which increases the loading capacity of the material tray 20 and improves work efficiency.

[0043] In the present application, the first visual inspection module 50 adopts a back-lighting inspection method, where the light source is on the inner ring of the material tray 20, and the camera is on the outer side of the material tray 20. The camera takes a photo of the gear on the material tray 20, and only a shadow is formed due to the backlight, so that the shape and size of the gear can be detected to see if it meets the standard. Since the light source illuminates from the inside to the outside, the radial side of the material tray 20 is translucent, otherwise the camera can only detect the upper part of the gear, but cannot detect the part of the gear hidden in the bearing slot 21, resulting in incomplete detection.

[0044] Specifically, the bearing groove 21 is extended obliquely along the rotation direction of the material tray 20; the direction of the gear conveying of the vibration feeder 10 is roughly parallel to the extension direction of the bearing groove 21 for receiving the gear, so as to convey the gear to the bearing groove 21. Even if the gear cannot smoothly enter the bearing groove 21 due to positional offset, the gear will re-enter the discharge port of the vibration feeder 10 under the push of the edge of the material tray 20, and will not be stuck between the discharge port of the vibration feeder 10 and the edge of the material tray 20.

[0045] Furthermore, a plurality of positioning posts 22 are provided at the bottom of the material tray 20 , and a plurality of first positioning holes 231 and a plurality of second positioning holes 232 are provided on the adapter tray 23 ; the positioning posts 22 are cooperatively connected with the first positioning holes 231 ; and the second positioning holes 232 are fixedly connected with the columns 40 .

[0046] In some embodiments, the positioning posts 22 of the material tray 20 are interference-fitted with the first positioning holes 231 , so that the material tray 20 is fixedly connected to the adapter tray 23 , which can effectively prevent the material tray 20 from being separated from the adapter tray 23 .

[0047] In other embodiments, the first positioning column 22 of the material tray 20 and the first positioning hole 231 are matched in a detachable manner, that is, clearance matching, and the clearance is controlled between 0.1 mm and 1 mm to prevent the material tray 20 from shaking relative to the adapter plate 23. Due to the small clearance, in order to facilitate disassembly and assembly, the upper end of the first positioning hole 231 can be set to a trumpet shape so that the positioning column 22 can be introduced into the first positioning hole 231 to assist assembly.

[0048] During the assembly of the material tray 20, it is only necessary to align the positioning column 22 of the material tray 20 with the first positioning hole 231 of the adapter tray 23, and then place the material tray 20 on the adapter tray 23, and the positioning column 22 enters the corresponding first positioning hole 231, so that the material tray 20 can be assembled. During disassembly, the material tray 20 is directly lifted from the bottom to the top, so that the positioning column 22 leaves the first positioning hole 231, and the material tray 20 can be removed. The disassembly and assembly process of the material tray 20 is relatively simple and quick. In addition, the material tray 20 can be replaced according to different gear types, so that the versatility of this solution is high.

[0049] Furthermore, the positioning column 22 includes a column core 221 integrally formed with the material tray 20 and a magnet set 222 sleeved on the outer side of the column core 221; the magnet set 222 can be connected to the positioning column 22 by in-mold injection molding. The magnet set 222 should be made of a high-temperature resistant magnetic material to avoid demagnetization during the in-mold injection molding process. For example, it can be one of a neodymium iron boron magnet, a samarium cobalt magnet, a ferrite magnet, and an aluminum nickel cobalt magnet. The adapter plate 23 is a component that can be magnetically attracted (i.e., including a ferromagnetic material), such as an iron component. After the magnet set 222 enters the first positioning hole 231, the magnetic attraction between the magnet set 222 and the adapter plate 23 can limit the positioning column 22 in the first positioning hole 231, and then limit the material tray 20 on the adapter plate 23, which can reduce the probability of the material tray 20 automatically detaching from the adapter plate 23.

[0050] Specifically, the rotating drive member 60 includes a rotating motor 610, a rotating shaft 620 and a mounting seat 630; the rotating motor 610 is fixedly mounted below the mounting seat 630; one end of the rotating shaft 620 is connected to the shaft of the rotating motor 610, and the other end passes through the mounting seat 630 and is fixedly connected to the turntable 30, and the rotating drive member 60 is fixedly mounted on the seat plate 80 through the mounting seat 630.

[0051] More specifically, the seat plate 80 is further provided with a mounting frame 53; the mounting frame 53 includes a first lifting mechanism 531 and a support plate 532 disposed on the first lifting mechanism 531; the support plate 532 is disposed parallel to the axis of the first visual detection module 50; the first camera 52 and the light emitting unit 51 are movably disposed on the support plate 532 through a first translation mechanism and a second translation mechanism, respectively. The first lifting mechanism 531 is used to control the support plate 532 and the first camera 52 and the light emitting unit 51 disposed on the support plate 532 to move in a vertical direction. The first translation mechanism and the second translation mechanism are used to control the first camera 52 and the light emitting unit 51 to move along the axis (i.e., along the support plate 532), respectively.

[0052] Furthermore, the seat plate 80 is also fixed with a second visual inspection module 70; the second visual inspection module 70 includes a second camera 72 and a second lifting mechanism 71; the second camera 72 is arranged on the second lifting mechanism 71 and above the bearing groove 21, and is used to shoot from top to bottom to detect the size and shape of the radial edge of the gear.

[0053] The second lifting mechanism 71 is used to control the second camera 72 to move in the vertical direction.

[0054] The first visual inspection module 50 combined with the second visual inspection module 70 can realize comprehensive inspection of gears using one device, which not only has high inspection efficiency but also has low implementation cost.

Those skilled in the art will understand that the present application is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present application.
