[0005] The transport device is used to transport the pipes, generally using rollers or wheels for conveying; the appearance inspection device is used to monitor the production quality of the outer surface of the pipes, such as surface flatness, outer diameter roundness, and surface roughness, and can specifically use 2D cameras, 3D cameras, or 3D laser scanners; the flipping device is used to flip the pipes from the first or second bracket to the first, second, or third product frame, and can specifically use a rotary motor in conjunction with a flipping block, or a linear drive component to push the pipes directly from the side, or a linear drive component in conjunction with an inclined push plate to lift the pipes from the bottom, and then the pipes fall from the side along the inclined push plate. The linear drive component can be a linear drive motor or cylinder, or a robotic arm can be used to achieve the flipping of the pipes; simultaneously The flipping device has the function of flipping the pipe from both sides. Specifically, the structure that can achieve single-sided flipping can be set to face both sides repeatedly. The main function of setting bidirectional flipping is to distinguish between qualified and unqualified products. The first bracket and the second bracket are used to support the pipe. Their working surfaces can be set as V-shaped or U-shaped surfaces, etc. The inclined guide plate is used to transfer the pipe from the first bracket to the second bracket. The first bracket is higher than the second bracket. The inclined guide plate is tilted towards the second bracket. The pipe is moved to the second bracket by gravity. The wall thickness detection device is used to detect whether the wall thickness of the product meets the production requirements. Specifically, a laser distance sensor can be set to extend from both ends of the pipe to measure the wall thickness. After measurement, it can be withdrawn and reset. Alternatively, a three-dimensional scanning device can be set to directly scan and calculate the pipe thickness.

[0006] The transport device moves the pipes backward, specifically behind the pipe transport device itself. The pipes move backward from the transport device located at the front, and after being scanned by the appearance inspection device, they arrive at the first bracket, located between the first and second product frames. The second bracket is located between the second and third product frames. The processing unit determines whether the pipes are qualified based on the scanned structure. If the inspection fails, a flipping device flips the pipes into the first product frame. If the inspection passes, the flipping device flips the pipes onto the inclined guide plate, and the pipes slide down to the second bracket. Then, a wall thickness inspection is performed. If the inspection fails, the flipping device flips the pipes from the material feeding gap into the second product frame. If the inspection passes, the flipping device flips the pipes into the third product frame. Furthermore, an alarm device is installed, connected to the processing unit. If a defective product is detected at any inspection stage, the alarm device will sound, reminding workers to handle the situation promptly. The alarm device includes an audible and visual alarm.

[0007] Preferably, the wall thickness detection device includes at least three three-dimensional vision sensors respectively disposed at both ends and above the second bracket, and all of the three-dimensional vision sensors are respectively connected to the processing unit for signal transmission.

[0008] A 3D vision sensor is set up to scan the pipe. The data is processed by the processing unit to obtain a 3D image of the pipe, and then information such as the outer diameter, length and wall thickness of the pipe is obtained. Then it is determined whether the information of the pipe meets the production requirements. There is at least one 3D vision sensor at each end of the pipe, and multiple 3D vision sensors can be set on the side and top of the pipe to improve the detection accuracy. Various types of 3D cameras can be used for the 3D vision sensor, with 3D line laser sensors being preferred.

[0009] Preferably, the appearance inspection device includes an annular mounting frame and a plurality of appearance inspection sensors respectively disposed in the inner circle of the annular mounting frame, and all of the appearance inspection sensors are respectively signal connected to the processing unit.

[0011] Preferably, it further includes a weighing device disposed on the first bracket or the second bracket, the weighing device being signal-connected to the processing unit.

[0012] The weighing device is used to weigh the pipes and determine whether the length and wall thickness of the pipes meet the production requirements by measuring the weight.

By combining the weight and the scanned three-dimensional image, the wall thickness and length of the pipes can be determined, making the detection results more accurate.

[0013] Preferably, the working surfaces of the first bracket and the second bracket are both V-shaped. The flipping device includes multiple lifting components respectively disposed on the first bracket or the second bracket, and a first inclined top plate and a second inclined top plate respectively disposed on the lifting components. The first inclined top plate and the second inclined top plate are inclined toward the two sides of the lifting components respectively. All the lifting components are signal connected to the processing unit respectively.

This component is signal-connected to the processing unit, allowing for angle adjustment based on the signal. This, in turn, adjusts the width of the discharge gap. When the pipe rolls from the inclined guide plate onto the second bracket, the inclination of the inclined guide plate can be adjusted to reduce the width of the discharge gap, allowing the pipe to roll relatively smoothly onto the second bracket. When the pipe on the second bracket needs to be flipped into the second product frame, the width of the discharge gap can be increased, allowing the pipe to pass through and fall into the second product frame.

[0019] Preferably, both the lifting component and the telescopic component are cylinders.

[0022] Before visual inspection, the coding device prints codes on the pipe, imprinting information such as the current production specifications and production serial number on the pipe. Then, the code reading device reads the codes and uploads the information such as the current production specifications and production serial number to the processing unit. In subsequent inspections, the processing unit compares the detected information with the information uploaded by the code reading device to determine whether the pipe is qualified.

[0023] Preferably, the device further includes a cutting device for cutting the pipe, which is disposed between the barcode reader and the first bracket. The cutting device is signal-connected to the processing unit, and the appearance inspection device is disposed on the cutting device.

The linear drive can be a linear drive motor or a cylinder, or a robotic arm can be used to achieve the flipping of the pipes; simultaneously, the flipping... Device 4 has the function of flipping the pipe from both sides. Specifically, the structure that can achieve single-sided flipping can be set to face both sides repeatedly. The main function of setting bidirectional flipping is to distinguish between qualified and unqualified products. The first bracket 3 and the second bracket 7 are both used to support the pipe. Their working surfaces can be set as V-shaped or U-shaped surfaces, etc. The inclined guide plate 6 is used to transfer the pipe from the first bracket 3 to the second bracket 7. The first bracket 3 is higher than the second bracket 7. The inclined guide plate 6 is tilted towards the second bracket 7. The pipe is moved onto the second bracket 7 by gravity slider. The wall thickness detection device 10 is used to detect whether the wall thickness of the product meets the production requirements.

Alternatively, a three-dimensional scanning device can be set to directly scan and calculate the pipe thickness.

[0042] The transport device 1 transports the pipes backward, which refers to the area behind the pipe transport device 1.

During the inspection process, the flipping device 4 distinguishes between qualified and unqualified products, preventing unqualified products from flowing into the production line. Workers can also observe in time whether unqualified products are generated, and then adjust the equipment or process in time to avoid a large number of unqualified products flowing out, thus ensuring production quality.

[0044] Example 2

[0045] The difference between Example 1 and Example 2 is as follows:

[0046] like Figures 2-4 As shown, the wall thickness detection device 10 includes at least three three-dimensional vision sensors 13 respectively disposed at both ends and above the second bracket 7, and all three-dimensional vision sensors 13 are signal-connected to the processing unit 11.

[0047] A 3D vision sensor 13 scans the pipe, and the data is processed by the processing unit 11 to obtain a 3D image of the pipe, thereby obtaining information such as the outer diameter, length, and wall thickness of the pipe.

Various 3D cameras can be used for the 3D vision sensors 13, with 3D line laser sensors being preferred. A ring-shaped mounting bracket 14 is used to install the appearance inspection sensor 15 in a ring. The pipe passes through the middle of the ring-shaped mounting bracket 14, and the appearance inspection sensor 15 scans the pipe from all sides, detecting pipes with unqualified appearances. A weighing device 16 is used to weigh the pipe, and the weight is used to determine whether the length and wall thickness of the pipe meet production requirements. Its measurement results can also be correlated with the wall thickness detection device 10. By combining the weight and the scanned 3D image, the wall thickness and length of the pipe are determined, making the detection results more accurate.

[0048] The remaining features and working principles of this embodiment are the same as those of Embodiment 1.

[0049] Example 3

[0050] Based on Example 1 or Example 2, Example 1 or Example 2 are further defined, with the following differences:

[0051] like Figure 2 , Figure 4 and Figure 5 As shown, the working surfaces of the first bracket 3 and the second bracket 7 are both V-shaped. The tilting device 4 includes multiple lifting components 17 respectively mounted on the first bracket 3 or the second bracket 7, and a first inclined top plate 18 and a second inclined top plate 19 respectively mounted on the lifting components 17. The first inclined top plate 18 and the second inclined top plate 19 are inclined towards the two sides of the lifting components 17, and all the lifting components 17 are signal-connected to the processing unit 11. Each first inclined top plate 18 and each second inclined top plate 19 has two lifting components 17 connected to its bottom. Figure 3 As shown, it also includes a bracket 24 and a telescopic member 20 that is signal-connected to the processing unit 11. The inclined guide plate 6 is rotatably connected to the bracket 24, and the fixed end and telescopic end of the telescopic member 20 are rotatably connected to the bracket 24 and the inclined guide plate 6, respectively. Both the lifting member 17 and the telescopic member 20 are cylinders. Figures 1-3 As shown, it also includes a coding device 21 and a code reading device 22 respectively disposed beside the transport device 1. The code reading device 22 is located behind the coding device 21 and is signal-connected to the processing unit 11. It also includes a cutting device 23 for cutting pipes disposed between the code reading device 22 and the first bracket 3. The cutting device 23 is signal-connected to the processing unit 11, and the appearance inspection device 2 is disposed on the cutting device.

[0052] The lifting component 17 raises either the first inclined top plate 18 or the second inclined top plate 19, causing the pipe to rise accordingly. Then, under the obstruction of the inclined top plate 18 or the second inclined top plate 19, the pipe falls to a predetermined side, thus achieving the flipping of the pipe. Each first inclined top plate 18 or second inclined top plate 19 has two lifting components 17 at its bottom, ensuring the smoothness of the lifting of the first inclined top plate 18 or the second inclined top plate 19 and accommodating heavier pipes. The inclined guide plate 6 is installed via the bracket 24 and is rotatably connected to the bracket 24. A telescopic component 20 drives the inclined guide plate 6 to rotate. The telescopic component 20 is signal-connected to the processing unit 11, and its angle is adjusted according to the signal, thereby adjusting the width of the discharge gap 12. When the pipe rolls from the inclined guide plate 6 onto the second bracket 7, the inclination of the inclined guide plate 6 can be adjusted to reduce the width of the discharge gap 12, allowing the pipe to roll relatively smoothly onto the second bracket 7. When the pipe on the second bracket 7 needs to be flipped into the second product frame 8, the width of the discharge gap 12 can be increased to allow the pipe to pass through and fall into the second product frame 8. Both the lifting component 17 and the telescopic component 20 are cylinders to reduce equipment costs. For the telescopic component 20, which requires adjustment of its extension length, a limit switch can be used for control. Before visual inspection, the coding device 21 prints codes on the pipe, imprinting information such as the current production specifications and production serial number onto the pipe. Then, the code reading device 22 reads the codes and uploads the information to the processing unit 11. During subsequent inspection, the processing unit 11 compares the detected information with the information uploaded by the code reading device 22 to determine whether the pipe is qualified. A cutting device 23 is set up to cut the pipe. The cutting device 23 cuts the pipe according to the pipe specifications read by the code reading device 22. At the same time, the visual inspection device 2 is set on the cutting device for easy installation and debugging.

[0053] like Figure 4 and Figure 6 As shown, the weighing device 16 includes a bottom support plate, a weight sensor mounted on the support plate, a weighing block mounted on the weight sensor, and a V-shaped working surface on the top of the weighing block that directly contacts the pipe.

[0054] like Figure 3 and Figure 7 As shown, the appearance inspection sensor 15 is uniformly installed in a ring on the ring mounting bracket 14.

[0055] The remaining working principles and processes of this embodiment are the same as those of Embodiment 1 or Embodiment 2.

For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

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