[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1 to 3 The present invention provides an automatic detection device for the surface pretreatment quality of workpieces, comprising a feeding conveyor belt 1, a discharging conveyor belt 2, a first visual inspection camera 3, a second visual inspection camera 4, a turning mechanism 5, and a controller 6. The feeding conveyor belt 1 and the discharging conveyor belt 2 are located at both ends of the turning mechanism 5, the first visual inspection camera 3 and the second visual inspection camera 4 are respectively installed on the top of the feeding conveyor belt 1 and the discharging conveyor belt 2, and the controller 6 is connected to the bottom end inside the turning mechanism 5.

[0021] During inspection, the feeding conveyor belt 1 transports the workpiece, the first vision inspection camera 3 performs visual inspection on one side of the workpiece, and then the flipping mechanism 5 automatically flips the workpiece. The flipped workpiece is transferred to the discharge conveyor belt 2, and then the second vision inspection camera 4 performs visual inspection on the other side of the workpiece.

[0022] The material turning mechanism 5 consists of a support base 7, a servo motor 8, a rotating support frame 9, a material turning conveyor belt assembly 10, a servo motor 11, a material blocking assembly 12, a material turning conveyor belt assembly 13, a servo motor 14, and a material blocking assembly 15. The servo motor 8 is fixedly connected to the top of one end of the support base 7. The rotating support frame 9 is rotatably connected to the top of the support base 7 and fixedly connected to the output shaft of the servo motor 8. The servo motors 8 and 11 are respectively fixedly connected to the rotating support frame 9. On both sides of one end of the support frame 9, the first material conveyor belt assembly 10 and the second material conveyor belt assembly 13 are rotatably connected to the inside of the rotating support frame 9. The first material conveyor belt assembly 10 and the second material conveyor belt assembly 13 are fixedly connected to the output shafts of the first servo motor 8 and the second servo motor 11, respectively. The first material blocking assembly 12 is installed on one side of the rotating support frame 9 and located at one end of the first material conveyor belt assembly 10. The second material blocking assembly 15 is installed on the other side of the rotating support frame 9 and located at one end of the second material conveyor belt assembly 13.

[0023] When flipping, the workpiece moves onto the flipping conveyor belt assembly 10. The servo motor 8 drives the rotating support frame 9 to rotate 180 degrees, thereby causing the workpiece to flip 180 degrees. At this time, the workpiece is limited by the stop assembly 12. After flipping, the workpiece is transferred to the top of the flipping conveyor belt assembly 23. Then, the workpiece is transported to the discharge conveyor belt 2 by the flipping conveyor belt assembly 23. Through the alternating operation of the flipping conveyor belt assembly 10 and the flipping conveyor belt assembly 23, continuous flipping can be achieved.

[0024] Both the first baffle assembly 12 and the second baffle assembly 15 are composed of a U-shaped support frame 16, a first cylinder 17, a second cylinder 18 and a limiting baffle 19. The U-shaped support frame 16 is fixedly connected to the rotating support frame 9. The first cylinder 17 and the second cylinder 18 are respectively connected through to both ends of the U-shaped support frame 16. The limiting baffle 19 passes through the U-shaped support frame 16 and is fixedly connected to the first cylinder 17 and the second cylinder 18. A strip-shaped limiting through groove 20 matching the limiting baffle 19 is opened on the U-shaped support frame 16. An anti-collision rubber pad 21 is fixedly installed on the side of the limiting baffle 19 near the rotating support frame 9.

[0025] When the first baffle assembly 12 and the second baffle assembly 15 are working, the first cylinder 17 and the second cylinder 18 drive the limit baffle 19 to move. The limit baffle 19 limits the workpiece, and the anti-collision rubber pad 21 can buffer the workpiece and reduce the impact force.

[0026] In operation, the system is equipped with a feeding conveyor belt, a discharging conveyor belt, a first vision inspection camera, and a second vision inspection camera to continuously transport and visually inspect workpieces, thereby determining their quality. A flipping mechanism, consisting of a support base, servo motor one, a rotating support frame, a flipping conveyor belt assembly one, a servo motor two, a stop assembly one, a flipping conveyor belt assembly two, a servo motor three, and a stop assembly two, enables the flipping of plate-shaped workpieces, facilitating double-sided inspection and improving the convenience and comprehensiveness of the inspection. Stop assemblies one and two, consisting of a U-shaped support frame, a first cylinder, a second cylinder, and a limit baffle, limit the workpiece's position during the flipping process, improving its stability and preventing it from falling.
