[0019] Hereinafter, an embodiment of the fully automatic appearance defect detection and multi-station turntable unloading device of the present invention will be described with reference to the accompanying drawings.

[0020] Figure 1-2 The fully automatic appearance defect detection and multi-station turntable unloading device of an embodiment of the utility model is shown, comprising a feeding turntable 1: a servo motor 2 is arranged at the bottom of the feeding turntable 1, a divider 3 is arranged at the bottom of the feeding turntable 1, the output end of the divider 3 is fixedly connected to the feeding turntable 1, the output shaft of the servo motor 2 is fixedly connected to the input end of the feeding turntable 1, a plurality of fixing seats 4 are annularly fixedly connected to the top of the feeding turntable 1, a unloading assembly 5 is arranged on the top of the fixing seat 4, the unloading assembly 5 includes a stepping motor 51 fixedly installed on the top of the fixing seat 4, and the top of the feeding turntable 1 The stepper motor 51 is fixedly mounted with a plurality of servo drivers 52 electrically connected to the stepper motor 51. The output shaft of the stepper motor 51 is fixedly connected with a threaded screw 53 through a coupling. The surface of the threaded screw 53 is threadedly connected with a threaded sleeve 54. The inner cavity of the threaded sleeve 54 is rotatably connected with two connecting rods 55. One end of the connecting rod 55 away from the threaded sleeve 54 is rotatably connected with a clamping arm 56. The bottom of the clamping arm 56 is fixedly connected with a guide sleeve 10. The top of the fixed seat 4 is fixedly connected with a fixed guide rail 11. The guide sleeve 10 is slidably connected to the surface of the fixed guide rail 11. The combination of the stepping motor 51 and the threaded screw 53 can push the threaded sleeve 54, and the threaded sleeve 54 and the connecting rod 55 can exert a force toward or away from the two clamping arms 56 on the same side, so that the clamping arms 56 can move toward each other, and the O-ring 6 can be removed, and the right side of the feeding turntable 1 can be moved. Two mounting brackets 7 are arranged on the side, a backlight panel 85 is fixedly connected to the bottom of the left side of the mounting bracket 7, an industrial camera 82, a fill light source 84 and the backlight panel 85 are located on the same central axis, a detection component 8 is arranged on the left side of the mounting bracket 7, the detection component 8 includes a camera bracket 81 fixedly connected to the top of the left side of the mounting bracket 7, an industrial camera 82 is fixedly installed on the left side of the camera bracket 81, a light source bracket 83 is fixedly connected to the middle of the left side of the fixing seat 4, a fill light source 84 is fixedly installed on the left side of the bottom of the light source bracket 83, and three material distribution barrels 9 are placed on the front side of the feeding turntable 1.

[0021] Working principle: When the utility model is used, the user conveys the O-ring 6 to the clamping range of the unloading assembly 5 through the feeding platform, and then the feeding turntable 1 drives the O-ring 6 to the designated detection position under the cooperation of the servo motor 2 and the divider 3, and then the industrial camera 82 is turned on to take pictures of the O-ring 6. When the industrial camera 82 is shooting, the fill light source 84 is automatically turned on to fill light for the O-ring 6, and the picture is detected by the visual algorithm, so as to identify whether the O-ring 6 has surface defects;

[0022] Then the feeding turntable 1 continues to rotate, and after the O-ring 6 reaches the top of the designated distribution barrel 9, the stepper motor 51 drives the threaded screw 53 to rotate through the coupling, and then the threaded screw 53 pushes the threaded sleeve 54 through its surface thread, so that the threaded sleeve 54 drives the two adjacent connecting rods 55 to rotate in an offset manner. During the offset process, the connecting rod 55 drives the clamping arm 56 to slide, so that the two clamping arms 56 located at adjacent positions move toward each other, and finally the two adjacent clamping arms 56 release the clamping of the O-ring 6, so that the O-ring 6 is detached from the surface of the clamping arm 56 and falls into the inner cavity of the corresponding distribution barrel 9.

[0023] To sum up: the fully automatic appearance defect detection and multi-station turntable unloading device, through the coordinated use of the feeding turntable 1 and the unloading component 5, transfers the O-ring 6 to the designated detection position, and then detects the O-ring 6 through the setting of the detection component 8. Finally, with the coordinated use of the unloading component 5 and the dividing barrel 9, the O-ring 6 is unloaded and classified for storage, thereby achieving the purpose of automated detection and classification and high detection efficiency.
