[0017] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0018] Please see Figures 1-4 A rapid automatic bullet appearance detection device includes: a detection station 1, a conveyor roller 2 installed on the top of the detection station 1, a feeder 3 set on one side of the detection station 1, the feeder 3 being located at the feeding end of the conveyor roller 2, a first detection camera 4 and a third detection camera 6 arranged sequentially above the conveyor roller 2, a second detection camera 5 and a fourth detection camera 7 respectively arranged on both sides of the conveyor roller 2, a flipping part 9 arranged in the middle of the conveyor roller 2, and a rejection part 8 arranged at the tail of the conveyor roller 2. The first inspection camera 4 collects image data of the product's outer surface; The third inspection camera 6 collects image data of the outer surface of the product after it has been flipped by the flipping part 9; The second inspection camera 5 collects image data of the product's tail. The fourth inspection camera 7 collects image data of the tip of the product.

[0019] The first detection camera 4, the second detection camera 5, the third detection camera 6, the fourth detection camera 7, the rejection unit 8, and the flipping unit 9 are all connected to the data processing module via wiring.

[0020] Specifically, the data processing module includes a Halcon Embedded vision system and a PLC controller. The acquired image data is transmitted to the Halcon Embedded vision system for analysis via the first inspection camera 4, the second inspection camera 5, the third inspection camera 6, and the fourth inspection camera 7. Then, the PLC controller executes specific instructions to achieve product flipping and rejection.

[0021] Furthermore, the rejection unit 8 includes an electric telescopic rod and a silicone rubber head 81. The silicone rubber head 81 is fixedly connected to the movable end of the electric telescopic rod. A hopper 10 is installed on the side of the tail position of the conveyor roller line 2. The rejection unit 8 pushes the unqualified products away from the conveyor roller line 2 and slides them from the hopper 10 into the waste collection unit. The electric telescopic rod is connected to the PLC controller through a circuit. When the Halcon Embedded vision system detects that a product is unqualified, it transmits a signal to the PLC controller and converts it into a rejection command. The delay time is calculated based on the position of the encoder on the conveyor line. The electric telescopic rod controls the silicone rubber head 81 to extend at the specified time and pushes the unqualified product into the hopper 10.

[0022] Furthermore, the flipping unit 9 includes a roller and a motor installed on the side of the conveyor roller line 2 to drive the roller to rotate. The roller contacts the outer surface of the product being transported on the conveyor roller line 2. The roller is driven to rotate by the motor, and then the product (the product is a bullet casing) is rotated under the action of friction. The rotation and flipping operation of the product is realized by accurately calculating the size and rotation speed of the roller in conjunction with the conveying speed of the conveyor roller line 2.

[0023] Furthermore, the first detection camera 4 and the third detection camera 6 are mounted directly above the conveyor roller line 2 via mounting brackets, and the second detection camera 5 and the fourth detection camera 7 are respectively mounted on both sides of the conveyor roller line 2 via mounting brackets. The second detection camera 5 and the fourth detection camera 7 are located on both sides of the flipping part 9, and the height of the second detection camera 5 and the fourth detection camera 7 is the same as the height of the top surface of the conveyor roller line 2, to ensure the accuracy of the image data collected by the second detection camera 5 and the fourth detection camera 7.

[0024] In this utility model, reference Figures 1 to 4 First, the feeder 3 transports the bullet casings onto the conveyor roller line 2. The bullet casings are transported from right to left along the conveyor roller line 2. First, they pass under the first inspection camera 4, which uploads the captured image data to the Halcon Embedded vision system. At the same time, the second inspection camera 5 also uploads the image data captured by the second inspection camera to the Halcon Embedded vision system. Then, the bullet casings are flipped over by the flipping part 9, causing the back of the bullet casings to be flipped up. When passing under the third inspection camera 6, the third inspection camera 6 captures its image data. At the same time, the fourth inspection camera 7 captures the image data of the tip of the bullet casings. The captured image data is then uploaded to the Halcon Embedded vision system. After the Halcon Embedded vision system makes a judgment, it transmits a rejection signal to the PLC controller. The PLC controller controls the electric telescopic rod to drive the silicone rubber head 81 to push the unqualified products out of the conveyor roller line 2.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
