Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of copper pipe detection devices, in particular to a copper pipe surface defect comprehensive detection device. BACKGROUND

[0002] As a key basic material widely used in refrigeration, heating, building water supply and drainage, and electronic and electrical fields, copper pipes, with their excellent thermal conductivity, corrosion resistance and plasticity, have become the core components of heat exchangers, piping systems and precision components. During the production and processing of copper pipes, factors such as the purity of raw materials, rolling / stretching process parameter fluctuations, and equipment wear can cause scratches, pits, cracks, oxidation stains, micropores, and inclusions on the surface of the copper pipes. These defects not only reduce the thermal efficiency and pressure strength of the copper pipes, but also can cause medium leakage, system energy efficiency degradation, and even equipment failure, seriously threatening the reliability and service life of the end products.

[0003] In combination with the above, it should be noted that the Chinese patent with application number CN2025100149512 discloses an environmentally friendly surface detection device for heat dissipation copper pipe production. The device is equipped with a turnover assembly, which facilitates the optical capture machine to capture the defects, flaws, or stains on the heat dissipation copper pipe. The optical capture machine can capture the surface of the copper pipe from multiple angles. When detecting copper pipes with curved shapes, the rotation ensures that all surfaces of the curved parts are captured, and the revolution further expands the detection coverage, greatly reducing the detection dead angle and thus better ensuring product quality. However, the above device only collects and detects the surface of the copper pipe during actual use, lacking effective detection of hidden micropores and hidden defects on the copper pipe body.

[0004] The Chinese patent with application number CN2023112442045 discloses a surface defect detection device for air conditioning and refrigeration copper pipes. The device can detect the surface defects of the inner and outer walls of the copper pipe through internal and external detection devices, and can achieve comprehensive and dead-angle-free detection of the copper pipe through rotating conveying, improving the detection efficiency and effect.

[0005] In summary, both technical solutions lack pressure boosting treatment for copper pipes during use, which makes hidden micropores and hidden defects on the copper pipe body not appear in time. Only surface detection can easily cause defects to be overlooked. Accordingly, when the copper pipe is used in conjunction with the interface area of the medium flow, the micropores or hidden defects may burst under the continuous pressure boosting of the internal medium, causing irreparable losses.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0037] Embodiment one: please refer to Figure 1 - Figure 12 As shown in the figure, the embodiment is a copper pipe surface defect comprehensive detection device, which comprises a detection disc body 1, a plurality of sleeve inspection devices 5 are embedded on the annular array of the side outer peripheral wall of the detection disc body 1, corner advancing air cylinders 504 are symmetrically arranged on the inner walls of the four corners of the sleeve inspection devices 5, a sleeve inspection movable inner pad 6 is arranged between the plurality of corner advancing air cylinders 504 in cooperation, and the surface of the sleeve inspection movable inner pad 6 is sequentially provided with an outer sleeve ring 602, an inner sleeve ring 606 and a storage disc 608 from outside to inside, thereby constructing a multi-point pneumatic expansion fixing for the clamped area of the copper pipe.

[0038] The copper pipe to be detected is clamped and transported by the feeding matching frame 3 to the area close to the detection disc body 1. The bottom of the copper pipe on the feeding matching frame 3 is sleeved on the pipe sleeve clamp 302. The pipe sleeve clamp 302 is replaced in advance according to the type of the copper pipe to be detected. The top surface of the feeding clamp seat 301 is provided with a rubber cushion covering the pipe sleeve clamp 302, so that the bottom of the copper pipe is sleeved on the pipe sleeve clamp 302. The surface of the pipe sleeve clamp 302 can be wrapped with rubber to contact the copper pipe and reduce the wear of the copper pipe during transportation. The feeding matching frame and the detection disc body 1 are used in linkage to realize a flow detection line and maintain efficient detection of the copper pipe.

[0039] The middle part of the detection disc body 1 is provided with a rotating shaft 101 connected with the support frame body 2 in a sleeving manner. The side edges of the detection disc body 1 are provided with a plurality of groups of sleeve cavities 102 connected with the sleeve detection device 5 in a matching manner. The inner walls of the sleeve cavities 102 are provided with centering push cylinders connected with the sleeve detection device 5 in a matching transmission manner. The feeding matching frame 3 is arranged symmetrically on both sides of the detection disc body 1. The middle part of the frame body of the feeding matching frame 3 is provided with a feeding clamp seat 301 matched with the sleeve detection device 5. The center of the feeding clamp seat 301 is provided with a replaceable pipe sleeve clamp 302.

[0040] When the feeding matching frame 3 transports the copper pipe to be detected close to the detection disc body 1, the detection disc body 1 is connected with the external driving motor in a transmission manner through the rotating shaft 101 and the shaft sleeve 202, so that the detection disc body 1 and the feeding matching frame 3 are kept in synchronous frequency operation. The detection disc body 1 rotates to drive the sleeve detection device 5 to rotate synchronously towards the feeding matching frame 3. In the state that the detection disc body 1 and the feeding matching frame 3 are kept in synchronous frequency operation, the opening of the sleeve cavity 102 is kept in alignment with the feeding clamp seat 301. The centering push cylinder drives the sleeve detection device 5 to slide along the inside of the sleeve cavity 102 to the opening area until the sleeve detection device 5 is matched and connected with the feeding clamp seat 301.

[0041] The top section of the sleeve detection device 5 is provided with a rectangular sealing groove 501 in a recessed manner. The sealing groove 501 is provided with a suction pipe and a sealing rubber pad. The top inner wall of the sleeve detection device 5 is provided with a scanning groove 502 in a recessed manner in a character shape. The scanning groove 502 is provided with a micro scanning sensor in a sleeved manner. The top of the scanning groove 502 is provided with a plurality of groups of circulating air grooves 503. The sleeve detection device 5 is a rectangular column with an open bottom structure.

[0042] During the matching and connecting of the sleeve detection device 5 and the feeding clamp seat 301, the sealing groove 501 and the feeding clamp seat 301 are kept in matched bolt connection. After the top adaptive part of the feeding clamp seat 301 is inserted into the sealing groove 501, the sealing groove 501 is connected with the external air supply equipment through the suction pipe to perform air suction treatment on the inside of the sealing groove 501. The sealing rubber pad is adsorbed and compressed to fill and seal the inside of the sealing groove 501, so as to build a sealed environment for the copper pipe between the sleeve detection device 5 and the feeding clamp seat 301.

[0043] The inner pad 6 in the sleeve detection activity is symmetrically provided with an inner pad sliding block 601 matched and connected with the corner pushing cylinder 504. The outer sleeve ring 602 and the inner sleeve ring 606 are arranged in a concentric circle structure, and the outer sleeve ring 602 is symmetrically embedded with an inflation air bag pad 603 on the adjacent ring wall of the inner sleeve ring 606.

[0044] During the docking of the opening of the sleeve detection device 5 and the feeding clamp seat 301, the scanning groove 502 is scanned and imaged by the copper pipe, and the difference between the scanning groove 502 and the pre-stored standard part imaging is compared by the main control computer of the device, and the data is stored, and the acquisition time, batch number and comparison result data log are constructed;

[0045] When the copper pipe is covered by the sealing ring frame, the corner pushing cylinder 504 drives the sleeve detection activity inner pad to slide to the opening area, until the top of the copper pipe is located between the outer sleeve ring 602 and the inner sleeve ring 606, the inflation air bag pad 603 is inflated to contact and clamp the inner and outer pipe walls of the top of the copper pipe, so that the copper pipe is preliminarily fixed, the lifting cylinder 605 drives the supporting ring 604 to slide downward to the opening area, so that the top of the copper pipe clamped between the outer sleeve ring 602 and the inner sleeve ring 606 is further pushed and blocked, and the sleeve detection activity inner pad is continuously slid downward under the driving of the corner pushing cylinder 504, so that the copper pipe is clamped and limited, the bottom of the copper pipe is contacted and supported by the pipe sleeve clamp 302 to maintain the direction, the rubber cushion is clamped, so that the copper pipe is sunk into the rubber cushion, the basic framework of the copper pipe body pressure detection is constructed, and the copper pipe body has been moved by the sleeve detection activity inner pad and adjusted by the supporting ring 604. If there is local damage or internal hollow, material defect or other abnormalities of the copper pipe body, the copper pipe body will have abnormal deformation, and the subsequent operation will be stopped, and the copper pipe with abnormal performance is directly judged as unqualified. The operation of the corner pushing cylinder 504 and the bracket cylinder has a front and back sequence, and cooperates to realize the fine clamping of the copper pipe.

[0046] The lifting cylinder 605 is embedded on the surface of the sleeve detection activity inner pad 6 between the outer sleeve ring 602 and the inner sleeve ring 606. The top of the lifting cylinder 605 is matched with the supporting ring 604. The center lifting cylinder 607 is embedded in the middle of the inner sleeve ring 606 and matched with the bottom wall of the storage disc 608. The inflation air bag pad 602 is embedded on the outer side of the storage disc 608. The top of the supporting ring 604 and the storage disc 608 is provided with a plurality of groups of circulating air holes.

[0047] The circulating gas groove 503 and the circulating gas holes in multiple regions of the sleeve detection movable inner pad surface construct the gas detection flow track. First, the circulating gas groove 503 continuously injects a certain strength of gas pressure outside the copper pipe of the sealing ring frame, realizes the pressure detection of the copper pipe body, and detects whether the copper pipe body has a micro-hole leakage and the like. The sleeve detection device 5 can detect the change of the gas pressure through the gas pressure sensor arranged on the inner wall and the inner sleeve ring 606 of the sleeve detection device 5, and whether there is a pressure drop change after the circulating gas groove 503 injects sufficient gas pressure in the gas detection flow track outside the copper pipe. After the gas pressure detection of the copper pipe outside is completed, a certain amount of gas pressure is injected into the copper pipe inside through part of the circulating gas holes, so as to realize whether there is a copper pipe body deformation or a gas pressure abnormality under the pressure difference environment between the inside and outside of the copper pipe.

[0048] After the gas detection flow track completes the gas pressure detection, the center lifting cylinder 607 drives the storage disc 608 to slide along the inside of the copper pipe to the opening area, and stops after approaching the center area inside the copper pipe. The second inflation air bag pad 609 on the storage disc 608 starts to inflate and expand to limit the inside of the copper pipe. In combination with the multi-group first inflation air bag pad 603, the pipe body bottom is wrapped and held from the inside and outside, and is supported by multiple points from the inside and outside. After the above steps are completed, the sleeve detection device 5 and the feeding device are about to be disconnected and separated. The corner advancing cylinder 504 and the lifting cylinder 605 keep resetting at a uniform speed, and the feeding clamp seat 301 keeps running to disconnect the clamping of the copper pipe bottom at the same time. The sleeve detection device 5 is reset into the sleeve cavity 102 by the centering advancing cylinder. The scanning groove 502 performs secondary scanning detection, data comparison and data recording on the copper pipe after the preliminary pressure increase detection through the scanning sensor. Thus, the preliminary overall detection process of the copper pipe is completed.

[0049] In the preliminary detection stage, the process integrates the pipe body strength detection, the inside and outside gas pressure detection and the twice scanning imaging comparison. The pipe body strength detection judges the deformation through the sleeve detection movable inner pad and the micro-adjusting pressure of the supporting ring. The inside and outside gas pressure detection detects the external pressure bearing and the micro-hole leakage, the deformation and the pressure drop detection under the pressure difference environment between the inside and outside. The complete data log containing the collection time and the batch order number is constructed synchronously, realizes the comprehensive coverage of the key quality indicators of the copper pipe, and lays a reliable foundation for the subsequent detection.
