Description

Technical Field

[0001] This utility model relates to the field of spliced ​​chopsticks detection technology, specifically a spliced ​​chopsticks detection device. Background Technology

[0002] A spliced ​​chopsticks inspection device is used to inspect the appearance and quality of spliced ​​chopsticks. Existing technologies generally use image recognition algorithms to detect surface defects such as cracks, scratches, and deformations. The algorithm compares a captured image of the spliced ​​chopsticks with a pre-set image of a standard spliced ​​chopstick. If the pixel difference exceeds a certain range, the spliced ​​chopsticks are determined to have an appearance defect.

[0003] However, existing detection devices are inconvenient for continuous detection and for classifying the spliced ​​chopsticks after detection, requiring manual assistance for detection. Therefore, we propose a spliced ​​chopsticks detection device to solve the above problems. Utility Model Content

[0013] Beneficial effects

[0014] This utility model provides a device for detecting spliced ​​chopsticks. Compared with the prior art, it has the following advantages:

[0015] This spliced ​​chopsticks detection device uses a servo motor to drive a drive wheel, which in turn moves a belt and a spliced ​​chopstick holder, moving the spliced ​​chopsticks on the holder towards the good product collection box. Simultaneously, through an imaging detection mechanism and an unloading mechanism, the device uses an image processing system inside the unloading mechanism to determine whether the spliced ​​chopsticks are qualified.

The unloading mechanism 12 includes an electric cylinder fixing frame 121, a servo electric cylinder 122, and a pressure rod 123. The electric cylinder fixing frame 121 is fixedly connected to the upper surface of the frame 3, the servo electric cylinder 122 is fixedly connected to the upper surface of the electric cylinder fixing frame 121, and the pressure rod 123 is fixedly connected to the upper movable end of the servo electric cylinder 122. A limiting mechanism 13 for limiting the deviation of the splicing chopsticks is fixedly connected to the upper surface of the frame 3. The limiting mechanism 13 includes a fixed plate 131, a bidirectional screw 132, a guide rod 133, and a limiting plate 134. The fixed plate 131 is fixedly connected to the upper surface of the frame 3. The bidirectional screw 132 is rotatably connected to the inner wall of the fixed plate 131. The guide rod 133 is fixedly connected to the inner wall of the fixed plate 131. The limiting plate 134 is threadedly connected to the outer wall of the bidirectional screw 132 and slidably connected to the outer wall of the guide rod 133. One end of the bidirectional screw 132 is equipped with a control panel for manually controlling the rotation of the bidirectional screw 132. The splicing chopstick holder 10 is provided to facilitate the placement of splicing chopsticks. The pressure rod 123 is provided to facilitate pressing down one end of the splicing chopsticks, thereby lifting up the other end and flipping the whole with the cooperation of the splicing chopstick holder 10.

The image processing system communicates with the PLC control unit, which controls the movement of the servo cylinder 122 through the output point.

[0025] Working principle: In use, firstly, the distance between the limiting plates 134 is adjusted by rotating the bidirectional screw 132, so that the spliced ​​chopsticks are relatively neatly arranged between the grooves of the spliced ​​chopstick holder 10. Then, the servo motor 7 drives the drive wheel 6 to rotate, which in turn drives the belt 9 to rotate, thereby causing the spliced ​​chopstick holder 10 and the spliced ​​chopsticks to move horizontally. By gradually moving the spliced ​​chopsticks to the imaging and detection mechanism 11, the camera device captures an image of the appearance of the spliced ​​chopsticks and uploads it to the image processing system for analysis. The image processing system determines whether the spliced ​​chopsticks are qualified. Then, when the unqualified spliced ​​chopsticks move to the bottom of the pressure rod 123, the servo cylinder 122 drives the pressure rod 123 to press down the unqualified spliced ​​chopsticks. The spliced ​​chopsticks are ejected into the interior of the defective product collection box 1. The qualified spliced ​​chopsticks are moved to the edge of the belt 9 by the drive wheel 6 and the driven wheel 5, and then fall naturally to the inner wall of the good product collection box 2.
