At present, the detection of tubular articles in industrial production mostly adopts manual visual observation. This detection method is highly subjective, and there are many false detections. In addition, manual operation has high labor intensity, so some tubular article detection equipment using cameras for visual detection has appeared. However, the tubular article detection equipment using cameras for visual detection is greatly affected by external light when detecting tubular articles. The brightness and color of light all affect the accuracy and consistency of detection, so the current tubular article detection equipment has the problems of poor accuracy and consistency of detection.

[0028] See Figures 1-8A tubular article detection device is disclosed, used to detect whether the shape, color, and pattern of a tubular article meet the requirements. The device includes a tubular article loading / unloading mechanism 1, a tubular article detection mechanism 2, and a frame 3. The frame 3 is the mounting structure for the device. Both the loading / unloading mechanism 1 and the detection mechanism 2 are mounted on the frame 3, forming a complete tubular article detection device. The detection mechanism 2 is vertically movable above the loading / unloading mechanism 1, allowing it to descend closer to the tubular article 4 for detection. The tubular item detection mechanism 2 includes a detection camera 21, a light shield 22, a mounting bracket 23, and a lifting drive assembly 24. Both the detection camera 21 and the light shield 22 are mounted on the mounting bracket 23. The lifting drive assembly 24 drives the mounting bracket 23 to move up and down, allowing the detection camera 21 and the light shield 22 to descend closer to the tubular item 4 for detection, facilitating inspection. Furthermore, when the tubular item 4 is being conveyed below, the detection camera 21 and the light shield 22 rise with the mounting bracket 23 to avoid obstructing the conveying of the tubular item 4. Except for the side closest to the tubular item loading / unloading mechanism 1, the detection camera 21 is surrounded by the light shield 22 on all other sides, ensuring that the detection device is not affected by external light, preventing the brightness and color of external light from affecting the accuracy and consistency of the detection, thereby improving the accuracy and consistency of the tubular item detection device. The lifting drive assembly 24 can be a lead screw mechanism.

[0029] See Figures 1-5The light shield 22 is equipped with a detection camera housing 221 and a tubular item housing 222. Both the detection camera housing 221 and the tubular item housing 222 are semi-enclosed structures with an opening on one side. The tubular item housing 222 is located on the side closer to the tubular item loading / unloading mechanism 1, and the detection camera housing 221 is located on the side away from the tubular item loading / unloading mechanism 1. The detection camera housing 221 is fitted onto the side of the tubular item housing 222 away from the opening. The detection camera 21 is installed inside the detection camera housing 221, which encloses the space where the detection camera 21 is located, preventing external light from affecting the detection by the detection camera 21. The tubular item housing 222 is used to hold the tubular item 4 to be detected. When the tubular item detection device is performing detection, the tubular item housing 222 covers the tubular item 4 to prevent external light from affecting the detection by the detection camera 21. The tubular item receiving box 222 has a detection opening 2221 on the side near the tubular item loading / unloading mechanism 1, facilitating the entry of the tubular item 4 conveyed by the tubular item loading / unloading mechanism 1 into the tubular item receiving box 222. The detection camera receiving box 221 has a light-transmitting slit 2211 on the side near the tubular item receiving box 222, facilitating the detection camera 21 to photograph the tubular item 4 for detection. The detection camera 21 can be a CCD camera, and the detection camera receiving box 221 and the tubular item receiving box 222 can be injection-molded plastic boxes.

[0030] See Figures 1-5 The camera receiving box 221 is detachably mounted on the mounting bracket 23, facilitating the removal of the camera receiving box 221 for maintenance and repair of the camera 21. A vertical slot can be provided on the camera receiving box 221, and an insertion block can be provided on the mounting bracket 23. The camera receiving box 221 is detachably mounted on the mounting bracket 23 through the cooperation of the slot and the insertion block. The tubular item receiving box 222 is fixedly mounted on the mounting bracket 23 using screws, bolts, rivets, etc.

[0031] See Figure 1 , 24-7, the tubular item loading and unloading mechanism 1 includes a rotation drive assembly 11, a turntable 12, and multiple tubular item fixing rods 13. The turntable 12 is rotatably mounted on the frame 3 via a rotating shaft. The rotation drive assembly 11 drives the turntable 12 to rotate. Each of the tubular item fixing rods 13 is evenly distributed on the turntable 12 and rotates with the turntable 12. Each of the tubular item fixing rods 13 is used to fix the tubular item 4 to be inspected, and to transport the tubular item 4 to be inspected to the tubular item inspection mechanism 2 for inspection. The rotation drive assembly 11 includes a motor 111 and a reducer 112. The reducer 112 is connected between the motor 111 and the turntable 12, so that the rotation drive assembly 11 can drive the turntable 12 to rotate at a low speed to transport the tubular item 4 to be inspected.

[0032] See Figure 1 , 2 In addition to the above, the tubular article loading and unloading mechanism 1 further includes a pushing and unloading assembly 14. The pushing and unloading assembly 14 includes a pushing block 141, a first unloading drive 142, and a second unloading drive 143. The pushing block 141 has an arc-shaped opening to abut against the tubular article fixing rod 13. The second unloading drive 143 is mounted on the frame 3. The first unloading drive 142 is fixed to the movable end of the second unloading drive 143 via a mounting bracket 144. Thus, the first unloading drive 142 can drive the pushing block 141 to move closer to or away from the tubular article fixing rod 13, and the second unloading drive 143 drives the pushing block 141 to unload the tubular article from the tubular article fixing rod 13. The first unloading drive 142 is a cylinder, and the second unloading drive 143 is a screw mechanism.

[0033] See Figure 6 The tubular item loading and unloading mechanism 1 further includes a rod rotation drive 16, which drives the tubular item fixing rods 13 to rotate. Each of the tubular item fixing rods 13 is rotatably mounted on the turntable 12 via bearings. The rod rotation drive 16 includes a motor and a belt. The motor rotates, driving the belt to rotate. When each tubular item fixing rod 13 rotates with the turntable 12, it can abut against the belt. Thus, the rotation of the belt can drive the tubular item fixing rods 13 to rotate. When the tubular item fixing rods 13 rotate, the tubular items 4 to be tested mounted on them rotate accordingly, sequentially rotating different parts of the tubular items 4 to be tested to the area below the tubular item testing mechanism 2. Thus, the tubular item testing mechanism 2 can perform all-round testing on the tubular items 4.

[0034] See Figure 1 and Figure 2The tubular article loading and unloading mechanism 1 also includes a loading conveyor belt 15, which is located below the turntable 12. The second loading drive component 143 drives the push block 141 to load and unload the tubular article 4 that has completed the inspection from the tubular article fixing rod 13 onto the loading conveyor belt 15, and then further transport it to the required position via the loading conveyor belt 15.

[0035] See Figure 1 and Figure 2 The frame 3 has an L-shaped structure. The second unloading drive component 143 and the unloading conveyor belt 15 are both mounted on the bottom wall 31 of the frame 3. The turntable 12 and the tubular item detection mechanism 2 are both mounted on the side wall 32 of the frame 3. Thus, the tubular item 4 is detected on the side wall 32 of the frame 3, and after detection, it is unloaded onto the bottom wall 31 of the frame 3. This design makes efficient use of space, reduces the volume of the frame 3 and the tubular item detection device, and facilitates the placement and relocation of the tubular item detection device. The frame 3 also includes adjustable feet 33, which are mounted on the bottom wall 31 of the frame 3. In uneven locations, the adjustable feet 33 can be used to adjust and stabilize the tubular item detection device.

[0036] See Figures 1-8In this embodiment, when the tubular item detection device is working, the tubular items 4 to be detected are first inserted sequentially into each tubular item fixing rod 13. The rotation drive assembly 11 drives the turntable 12 to rotate, and each tubular item fixing rod 13 rotates with the turntable 12 to sequentially transport each tubular item 4 to the tubular item detection mechanism 2 for detection. When the tubular item 4 to be detected is below the tubular item detection mechanism 2, the lifting drive assembly 24 drives the mounting bracket 23 to descend, so that the detection camera 21 and the light shield 22 descend with the mounting bracket 23 and approach the tubular item 4. The tubular item receiving box 222 covers the tubular item 4, and the detection camera 21 takes pictures of the tubular item 4 through the light-transmitting slit 2211 inside the detection camera receiving box 221 to detect the tubular item 4, avoiding external light from affecting the detection camera 21's detection of the tubular item 4. When the detection camera 21 detects the tubular item 4, the rod rotates to drive the rotation drive assembly 11 to rotate. The actuator 16 drives the tubular item fixing rod 13 to rotate, and the tubular item 4 to be detected rotates with the tubular item fixing rod 13, so that the detection camera 21 can perform all-round detection of the tubular item 4. After the tubular item 4 is detected, the lifting drive assembly 24 drives the mounting bracket 23 to rise, and the detection camera 21 and the light shield 22 move away from the tubular item 4 with the mounting bracket 23. The tubular item fixing rod 13 moves away from the tubular item detection mechanism 2 with the turntable 12 and moves to the position of the pusher and unloading assembly 14. The first unloading drive assembly 142 can drive the pusher block 141 to approach the tubular item fixing rod 13 and abut against the end face of the tubular item 4. The second unloading drive assembly 143 drives the pusher block 141 to unload the tubular item from the tubular item fixing rod 13 onto the unloading conveyor belt 15, and then continue to transport it to the required position through the unloading conveyor belt 15.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
