[0002] As a type of profile widely used in the manufacture of furniture, fitness equipment and precision instruments, the appearance quality and dimensional consistency of flat round metal tubes are of paramount importance.

[0003] Patent CN222220362U discloses a quality inspection device for flat metal tubes, including a detection component, a belt conveyor, and a feeding component, all mounted on the ground and cooperating with each other. The feeding component includes a housing and a conical cylinder fixedly connected to the inner wall of the housing. A discharge chute is provided on the inner wall of the housing near the belt conveyor, and a guide frame is inclinedly arranged inside the housing. Two symmetrically arranged limiting blocks are fixedly installed on the inner wall of the guide frame near the discharge chute, and a sorting chute is provided on the inner wall of the guide frame on the opposite side of the two limiting blocks. This invention, by setting up a guide frame and limiting blocks, utilizes the inclination of the guide frame to allow the flat metal tubes to slide to the limiting blocks. The limiting blocks restrict the angle at which the flat metal tubes pass, thereby enabling batch feeding of flat metal tubes at the same angle, improving feeding efficiency while ensuring consistent feeding results.

[0004] The aforementioned patent achieves automated feeding by setting up a feeding component, but the material size needs to be kept consistent, which cannot be met when changing to materials of different specifications.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 The metal flat round tube quality detection device in this embodiment includes a support frame 1 and a base 2. The device is characterized in that a vibrating plate 3 is provided on the top of the base 2, and a flow guiding structure 4 is provided between the vibrating plate 3 and the support frame 1.

[0022] The flow guiding structure 4 includes a flow guiding plate 401. One end of the flow guiding plate 401 is fixedly connected to the vibrating plate 3 and the other end is fixedly connected to the support frame 1. A telescopic rod 402 is fixedly connected to the outside of the flow guiding plate 401, and a movable plate 403 is fixedly connected to the driving end of the telescopic rod 402.

[0023] The discharge port of the vibratory feeder 3 is equipped with a flexible baffle 301. One end of the flexible baffle 301 is fixedly connected to the vibratory feeder 3, and the other end is fixedly connected to the movable plate 403. The flexible baffle 301 connects the discharge port of the vibratory feeder 3 and the movable plate 403, forming a flexible sealing or guiding channel. When the telescopic rod 402 drives the movable plate 403 to adjust, the flexible baffle 301 can deform flexibly accordingly, always ensuring the continuity of the channel. This effectively avoids the metal flat round tube from getting stuck, jumping or being scratched on the surface during the transfer from the vibratory feeder 3 to the guide structure 4, ensuring smooth and stable feeding, while reducing noise and wear during equipment operation.

[0024] Support rod 7 is fixedly connected to the outside of support frame 1. Connecting rod 8 is fixedly connected to support rod 7. Visual inspection camera 9 is fixedly connected to the bottom of connecting rod 8. By setting up a visual inspection system composed of support rod 7, connecting rod 8 and visual inspection camera 9, automated and non-contact inspection of pipe material quality is realized. This structure uses support rod 7 and connecting rod 8 to accurately and stably suspend visual inspection camera 9 above the inspection station, providing an ideal viewing angle and a stable installation foundation for image acquisition. Visual inspection camera 9 can identify surface defects, specifications, dimensions and orientation of pipe material, thereby upgrading the inspection device from a simple structural measurement to an intelligent system with comprehensive quality judgment capabilities, greatly improving the accuracy and efficiency of inspection.

[0025] The support frame 1 has a flow guide groove 101 inside. The flow guide groove 101 is V-shaped and communicates with the flow guide plate 401. By opening the V-shaped flow guide groove 101 inside the support frame 1, it plays a key positioning and guiding role. The V-shaped design can naturally accommodate and guide the flat round metal tube, so that it automatically rolls to the center of the bottom of the groove under the action of gravity, thereby realizing the automatic centering of the tube. This ensures that each tube to be inspected can pass through the inspection area in a uniform and standard posture, providing a stable position reference for the subsequent accurate measurement and judgment by the visual inspection camera 9, and eliminating the inspection error caused by the position deviation of the tube.

[0026] A first motor 5 is fixedly connected to the outside of the support frame 1. A stop bar 6 is fixedly connected to the output shaft of the first motor 5. The first motor 5 serves as a power source and can precisely control the rotation of the stop bar 6. When the stop bar 6 rotates to extend into the guide channel 101, it can block the subsequent pipe from moving forward. When it is necessary to release the pipe, the stop bar 6 rotates out of the guide channel 101, and the pipe can continue to flow under the action of gravity. This mechanism allows the pipes to pass through the inspection station one by one in an orderly manner, avoiding the phenomenon of multiple pipes piling up and overlapping. This ensures that the visual inspection camera 9 can independently and clearly capture images of each pipe, thus ensuring the effectiveness of the inspection.

[0027] The top of the support frame 1 has a groove 102 that matches the baffle 6. The baffle 6 extends into the guide channel 101. The visual inspection camera 9 is located at the top of the guide channel 101. By opening the groove 102 that matches the baffle 6 and positioning the inspection area of ​​the visual inspection camera 9 at the top of the guide channel 101, the equipment structure and workflow are optimized. The groove 102 provides storage space for the baffle 6 when it is not performing its blocking function, allowing it to completely exit the guide channel and avoid any interference with the flow of the pipe. At the same time, the position of the visual inspection camera 9 is clearly set directly above the guide channel 101 and behind the blocking point of the baffle 6. This means that the pipe enters the camera's field of view for inspection only after being precisely positioned by the baffle 6. This spatial layout allows the positioning function of the baffle 6 and the inspection function of the camera to be seamlessly connected, forming an efficient and orderly automated inspection process.

[0028] When implementing this procedure, please follow these steps:

[0029] 1) First, turn on the power of the device, put the batch of metal flat round tubes to be tested into the vibratory plate 3, the vibratory plate 3 starts to work, and through vibration, arranges the messy tubes in an orderly manner and transports them to the inlet of the guide structure 4.

[0030] 2) Then, according to the specifications of the pipe being tested, control the telescopic rod 402 to move and drive the movable plate 403 to move, thereby adjusting the channel width formed by the guide plate 401 to match the pipe size. The flexible baffle 301 deforms accordingly to ensure that the pipe is smoothly and without damage guided into the V-shaped guide groove 101 on the support frame 1.

[0031] 3) Further inspection is carried out. The pipe slides down the V-shaped guide groove 101 by gravity. At this time, the first motor 5 drives the stop rod 6 to rotate and extend into the guide groove 101, blocking the pipe at the preset inspection station for precise positioning. After the pipe stops, the visual inspection camera 9 above is triggered to collect images of the stationary pipe to analyze its surface quality, size or orientation.

[0032] Finally, after sorting and unloading, the vision system completes the analysis and outputs the results. Then, the first motor 5 is activated again, driving the stop bar 6 to rotate and exit the guide trough 101. The inspected pipes are guided to different collection areas by the subsequent sorting mechanism according to the judgment results, thus completing the full-process inspection of a pipe and starting the next cycle.

[0033] In summary, this metal flat round tube quality inspection device achieves flexible adjustment of the width and angle of the feeding channel by setting a flow guiding structure 4 composed of a flow guide plate 401, a telescopic rod 402, and a movable plate 403. A flexible sealing transition is achieved by setting a flexible baffle 301 between the outlet of the vibrating plate 3 and the movable plate 403. An automated, non-contact intelligent inspection of the tube surface defects, dimensions, and orientation is achieved by setting a visual inspection system composed of a support rod 7, a connecting rod 8, and a visual inspection camera 9. Automatic centering and precise positioning of the tube are achieved by setting a V-shaped flow guide trough 101 inside the support frame 1, ensuring that the tube passes through the inspection area in a uniform posture. Intermittent blocking and release of the tube are achieved by setting a baffle 6 driven by the first motor 5. Finally, by setting a groove 102 that matches the baffle 6 and precisely positioning the visual inspection camera 9 on the top of the flow guide trough 101, the positioning function of the baffle 6 and the inspection function of the camera are achieved in a spatial and logical efficient synergy.
