Description

Technical Field

[0001] This utility model relates to the technical field of corrugated pipe testing equipment, and specifically discloses a non-contact testing device for corrugated pipes. Background Technology

[0002] Plastic corrugated pipe is a double-walled plastic pipe with an outer ring-shaped corrugated structure and an inner smooth wall. Compared with solid-walled pipes of the same strength, it has the advantages of being environmentally friendly and energy-saving, having reliable connections, good low-temperature impact resistance, good stress crack resistance, good chemical corrosion resistance, good aging resistance, good wear resistance, good toughness, high pressure resistance, and long service life.

[0003] Corrugated pipes coming off the production line need to be inspected. Currently, industrial vision inspection is used in the market, which greatly improves efficiency.

[0004] Chinese patent (patent number: CN218014209U, disclosing a corrugated pipe defect detection device) describes a device that uses a conveying assembly to transport corrugated pipes, which slide down onto a ramp into a U-shaped plate. A visual inspection device then checks the corrugated pipes to determine their quality. If qualified, a drive motor rotates a rotating rod, causing a straight toothed plate to move forward, which in turn moves the U-shaped plate forward, placing the corrugated pipe into the first through-hole. If unqualified, the drive motor rotates the rotating rod in the opposite direction, causing the straight toothed plate to move backward, which in turn moves the U-shaped plate backward, placing the corrugated pipe into the second through-hole. This device facilitates the classification of inspected corrugated pipes, automatically separating qualified and unqualified products, preventing confusion, and reducing the workload of workers.

[0005] However, when the above-mentioned device is in use, the corrugated pipe becomes static after sliding down the inclined platform into the U-shaped plate, which makes it impossible for the visual inspection equipment to identify and inspect the corrugated pipe from all angles. This results in poor detection of corrugated pipe defects. In addition, because the U-shaped plate structure is fixed and cannot be adjusted, it cannot adapt to corrugated pipes of different diameters and has poor versatility. Utility Model Content

[0006] This invention proposes a non-contact inspection device for corrugated pipes. The device drives the corrugated pipe to rotate dynamically through a support roller, and combines it with a vision inspection device for multi-angle scanning, which improves the defect recognition rate and effectively enhances the inspection accuracy. The electric push rod adjusts the distance between the two rollers to adapt to different pipe diameters, making it highly versatile and meeting diverse production needs.

The partition divides the interior of the guide groove into two equal-sized cavities.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figure 1-4 A non-contact inspection device for bellows, comprising:

[0028] Base 1, bracket 2 is fixedly installed on the top of base 1, and visual inspection equipment 3 is installed on the top of bracket 2;

[0029] The support rotation assembly includes two electric push rods 4 located below the vision inspection device 3. The two electric push rods 4 are horizontally arranged and symmetrically distributed. The output ends of the two electric push rods 4 are fixedly connected to roller frames 5, and the inner sides of the two roller frames 5 are rotatably connected to support rollers 6.

[0030] The sorting mechanism includes a guide groove 8 located directly below two support rollers 6. The guide groove 8 has an umbrella-shaped structure in its main view and a partition 9 is fixedly connected to its inner side. The partition 9 divides the interior of the guide groove 8 into two equal-sized cavities.

[0031] Feeding assembly.

[0032] In this embodiment: the corrugated pipe enters between two support rollers 6 via the conveying assembly 10 and the guide ramp 11. The electric push rod 4 adjusts the distance between the two rollers to adapt to different pipe diameters, which is highly versatile and meets diverse production needs. The motor 16 drives the support rollers 6 to rotate, which in turn drives the corrugated pipe to rotate at a constant speed. The vision inspection device 3 captures surface images from multiple angles. The support rollers 6 drive the corrugated pipe to rotate dynamically. Combined with the multi-angle scanning of the vision inspection device 3, the static inspection blind spots are eliminated, the defect recognition rate is improved, and the inspection accuracy is effectively improved.

[0033] After the test is completed, the PLC control system instructs the servo motor 17 to move according to the result, and drives the guide groove 8 to swing left and right through the hinge seat 7, so that the bellows is guided into the corresponding cavity separated by the partition 9, and finally slides down into the storage tank 15, completing the automatic classification of qualified and unqualified products, significantly reducing manual intervention.

[0034] During the sorting process, the support plate 12 and the buffer spring 14 absorb the impact force, and the umbrella-shaped structure of the hemispherical support rib 13 and the guide groove 8 ensures that the bellows slides smoothly and reduces collision damage.

[0035] The visual inspection device 3 records an external photo of the corrugated pipe through a camera and performs identification and judgment through an internal recognition unit (which can compare it with the internal database) to detect whether the corrugated pipe is qualified. All of these can be achieved with existing technologies, which will not be elaborated here.

[0036] As a technical optimization of this utility model, the feeding assembly includes a conveying assembly 10 disposed on one side above the supporting rotating assembly, and a guide ramp 11 is provided at one end of the conveying assembly 10.

[0037] In this embodiment, a guide ramp 11 is provided at one end of the conveying assembly 10 to facilitate the conveying of the corrugated pipe between the two support rollers 6.

[0038] As a technical optimization of this utility model, the sorting mechanism also includes two support plates 12 located on the left and right sides below the guide groove 8. The upper surfaces of the two support plates 12 are fixedly connected with hemispherical support ribs 13, and two buffer springs 14 are provided between the two support plates 12 and the base 1.

[0039] In this embodiment: the support plate 12 and the buffer spring 14 absorb the impact force, and the umbrella-shaped structure of the hemispherical support rib 13 and the guide groove 8 ensures that the bellows slides smoothly and reduces collision damage.

[0040] As a technical optimization of this utility model, the sorting mechanism also includes a hinge seat 7 fixedly connected to the middle of the upper end face of the base 1, and the bottom of the guide groove 8 is rotatably connected to the hinge seat 7.

[0041] In this embodiment, the bottom of the guide groove 8 is rotatably connected to the hinge seat 7, so that the guide groove 8 can swing left and right to guide qualified and unqualified corrugated pipes into the corresponding storage tank 15.

[0042] As a technical optimization of this utility model, storage troughs 15 are provided on both the left and right sides of the upper end face of the base 1, and outlets that communicate with the two storage troughs 15 are provided on both the left and right side walls of the base 1.

[0043] In this embodiment, the left and right side walls of the base 1 are provided with outlets that are respectively connected to two storage tanks 15. During use, collection boxes or conveyor belts can be set at the two outlets so that the corrugated pipes inside the storage tanks 15 can be discharged, collected and transported, which is convenient to use.

[0044] As a technical optimization of this utility model, a motor 16 for driving the support roller 6 to rotate is installed on the outer wall of one of the roller frames 5, and a servo motor 17 for driving the guide groove 8 to swing is installed on the outer wall of the hinge seat 7.

[0045] In this embodiment: the motor 16 is used to drive the support roller 6 to rotate, thereby driving the corrugated pipe to rotate at a constant speed, and the servo motor 17 provides power for the swing of the guide groove 8.

[0046] As a technical optimization of this utility model, both electric push rods 4 are fixedly connected to the bracket 2 through a fixing plate, and the vision inspection device 3, electric push rods 4, conveying assembly 10 and servo motor 17 are all electrically connected to the external PLC control system.

[0047] In this embodiment, the PLC centrally controls modules such as vision inspection, electric actuators, and conveying components, realizing the integration of the entire "inspection-sorting-collection" process and enabling rapid integration into production lines.

[0048] The working principle and usage process of this utility model are as follows: During use, the corrugated pipe enters between two support rollers 6 via the conveying assembly 10 and the guide ramp 11. The electric push rod 4 adjusts the distance between the two rollers to adapt to different pipe diameters. The motor 16 drives the support rollers 6 to rotate, causing the corrugated pipe to rotate at a constant speed. The vision inspection device 3 captures surface images from multiple angles. After the inspection is completed, the PLC control system instructs the servo motor 17 to move according to the results. The servo motor 17 drives the guide groove 8 to swing left and right through the hinge seat 7, guiding the corrugated pipe into the corresponding cavity separated by the partition 9. Finally, it slides down to the storage tank 15, completing the automatic classification of qualified and unqualified products. During the sorting process, the support plate 12 and the buffer spring 14 absorb the impact force. The hemispherical support rib 13 and the umbrella-shaped structure of the guide groove 8 ensure that the corrugated pipe slides down smoothly, reducing collision damage.
