Description

TECHNICAL FIELD

[0001] The present application relates to the field of heat dissipation copper pipe detection, in particular to an environmentally friendly heat dissipation copper pipe production surface detection device. BACKGROUND

[0002] The environmentally friendly heat dissipation copper pipe production surface detection device is a professional equipment for checking the surface quality of heat dissipation copper pipes. In the production process of heat dissipation copper pipes, various defects may appear on the surface, such as scratches, pits, oxide layers, and impurity adhesion. This detection device is designed to accurately detect these surface problems and ensure that the produced heat dissipation copper pipes meet the quality standards, especially the environmental protection requirements.

[0003] The traditional heat dissipation copper pipe surface detection device on the market has many drawbacks and adverse effects. First, the detection angle is limited. Most traditional devices use fixed angle or simple linear scanning methods, which cannot cover the copper pipe surface in all directions, especially in curved and irregular parts. This may miss flaws, defects, and stains, leading to inaccurate detection results. As a result, copper pipes with quality problems may flow into subsequent processes, reducing the overall product quality and affecting the heat dissipation performance of heat dissipation copper pipes in electronic equipment and other application scenarios, even causing equipment failure. Second, the detection path lacks flexibility. Traditional devices are difficult to quickly adjust the detection path when facing different shapes and specifications of copper pipes. Complex mechanical adjustments or manual operations are often required, which is tedious and time-consuming. This seriously affects production efficiency and increases production costs, making it difficult to meet the rapid and diversified detection needs in large-scale production, restricting the production capacity and market competitiveness of enterprises. Third, the detection efficiency is low. Due to the defects in detection angle and path, multiple repeated detections or manual assistance in turning over and adjusting position are required, which not only consumes a lot of time but also introduces errors due to the instability of manual operation, reducing the reliability of detection results. Frequent false positives and false negatives result in uneven product quality, affecting enterprise reputation and customer satisfaction, and bringing potential economic losses and market risks to enterprises.

[0004] Secondly, the traditional surface inspection devices for heat dissipation copper tubes on the market lack adaptability to copper tubes of different sizes in terms of fixing copper tubes. The fixing structure of most traditional devices is single and fixed, and can only detect copper tubes of specific sizes. When faced with copper tubes of different diameters, the fixing method cannot be flexibly adjusted. This forces companies to equip inspection devices of various specifications, reducing production efficiency, and frequent replacement operations can easily cause wear on the devices, affecting the stability of inspection accuracy; secondly, traditional fixing methods often make it difficult to ensure the stability of copper tubes during the inspection process. For example, some simple clip fixing methods, when the inspection equipment is running, the copper tubes are prone to displacement and shaking due to vibration or slight collisions, making it impossible for optical inspection equipment to accurately capture flaws, defects or stains on the surface of the copper tubes, resulting in frequent missed or false detections; thirdly, the traditional device structure takes up a large amount of production space, which is a serious problem for companies with limited production space, restricting the company's production layout optimization and increasing site costs.

[0005] Therefore, it is necessary to provide an environmentally friendly surface detection device for heat dissipation copper tube production to solve the above problems. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the present invention aims to provide an environmentally friendly surface detection device for the production of heat-dissipating copper tubes.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a surface detection device for the production of environmentally friendly heat-dissipating copper tubes, comprising a detection platform, an optical capture machine, a first heat-dissipating copper tube, a second heat-dissipating copper tube, and a third heat-dissipating copper tube. The optical capture machine is arranged on the top of the detection platform, and the first heat-dissipating copper tube, the second heat-dissipating copper tube, and the third heat-dissipating copper tube are all arranged above the detection platform. A flip component for assisting the first heat-dissipating copper tube, the second heat-dissipating copper tube, and the third heat-dissipating copper tube to rotate is provided on the top of the detection platform, and a fixing component for fixing the first heat-dissipating copper tube, the second heat-dissipating copper tube, and the third heat-dissipating copper tube is provided above the detection platform.

[0008] Preferably, the flipping assembly includes a positioning frame, the positioning frame is fixedly connected to the top of the detection table, the top of the positioning frame is fixedly connected to a driving device, the output shaft of the driving device is fixedly connected to a power conversion disk, the outer wall of the power conversion disk is annular and fixedly connected to a rotating rod group, and the top of the positioning frame is fixedly connected to a gear disk.

[0009] Preferably, the turnover assembly further comprises a square chute, the square chute is arranged at the end of the rotating rod group away from the power conversion disc, a limiting slider is slidably connected in the square chute, a gear rod is rotatably connected in the limiting slider, a reset spring is fixedly connected to the outer wall of the limiting slider, and the end of the reset spring away from the limiting slider is fixedly connected to the rotating rod group.

[0010] Preferably, the fixing assembly comprises a fixing block, the fixing block is fixedly connected to the bottom of the gear disc, a cylindrical fixed groove is arranged in the bottom of the fixing block, and a threaded rotating block is threadedly connected to the bottom of the fixing block.

[0011] Preferably, the fixing assembly further comprises a communication groove, the communication groove is arranged in the interior of the threaded rotating block, a limiting ring is fixedly connected to the top of the inner cavity of the fixing block, and an elastic extrusion sheet is annularly arranged and fixedly connected to the bottom of the limiting ring.

[0012] Preferably, the buffer pad is fixedly connected to the two sides of the reset spring, and the gear rod is engaged with the gear disc.

[0013] Preferably, the communication groove is in communication with the cylindrical fixed groove.

[0014] Preferably, the top of the threaded rotating block is arranged in an inclined manner, the bottom of the elastic extrusion sheet is arranged in an inclined manner, and the inclined surfaces of the threaded rotating block and the elastic extrusion sheet are opposite.

[0015] The surface detection device for the production of the environment-friendly heat dissipation copper pipe has the following beneficial effects compared with the prior art:

[0016] 1. Through the arrangement of the turnover assembly, after the heat dissipation copper pipe is fixed at the bottom of the gear rod, the power conversion disc drives the rotating rod group to rotate, the rotating rod group drives the limiting slider to rotate along the outer wall of the gear disc, the gear rod is revolved along the outer side of the gear disc, the gear rod drives the heat dissipation copper pipe to rotate, and then the optical capturing machine can shoot the defects, flaws or stains of the heat dissipation copper pipe, compared with the traditional heat dissipation copper pipe surface detection device which adopts a fixed shooting angle or a simple linear movement detection mode, the above structure can make the optical capturing machine shoot the surface of the copper pipe from multiple angles, for example, when detecting a copper pipe with a curved shape, the rotation can ensure that each surface of the curved part can be shot, and the revolution further expands the coverage of the detection, greatly reduces the dead angle of the detection, significantly improves the comprehensiveness and accuracy of the detection, and better guarantees the product quality.

[0017] Secondly, the traditional detection device can only move the detection equipment along a fixed straight line or a simple preset path to scan the surface of the copper pipe, while the above structure can move the heat dissipation copper pipe along a specific path by changing the shape of the gear disc, which provides great flexibility for detecting copper pipes of different shapes and specifications. For example, for some heat dissipation copper pipes with special curvature or special shape, by customizing the corresponding shape of the gear disc, the surface of the copper pipe can be easily and accurately detected without the need for large-scale modification of the entire detection device, improving the versatility and adaptability of the detection device and better meeting complex production tasks.

[0018] Secondly, due to the setting of the reset spring and the buffer pad, the limiting slide block drives the gear rod to always abut against the gear disc, thereby ensuring the stability of the gear rod driving the heat dissipation copper pipe to rotate, and at the same time, after replacing the gear disc of different shapes, the buffer pad can reduce the friction of the limiting slide block on the rotating rod group, thereby improving the service life of the equipment.

[0019] 2. By the setting of the fixing assembly, after the worker passes the heat dissipation copper pipe through the communication groove and the cylindrical fixed groove, the threaded rotating block is rotated to abut against the inclined surface of the elastic pressing piece, and finally the elastic pressing piece abuts against the heat dissipation copper pipe, thereby achieving the purpose of fixing heat dissipation copper pipes of different sizes. Traditional heat dissipation copper pipe surface detection devices often design fixing structures for specific size copper pipes. When different size copper pipes need to be detected, different clamps or mechanical parts of the device need to be replaced, increasing production cost and equipment complexity.

[0020] The above structure abuts against the inclined surface of the elastic pressing piece by rotating the threaded rotating block, and then the elastic pressing piece abuts against heat dissipation copper pipes of different sizes to achieve self-adaptive fixing of copper pipes of various sizes. For example, when facing a small diameter copper pipe, only the threaded rotating block needs to be rotated, and the elastic pressing piece can tightly fit the surface of the copper pipe. For a larger diameter copper pipe, continue to rotate the threaded rotating block, and the elastic pressing piece will gradually tighten, always keeping the copper pipe effectively fixed. This makes the detection device quickly and conveniently adapt to the detection needs of copper pipes of different sizes without complex component replacement or adjustment process, greatly improving the versatility and production efficiency of the detection device, reducing production cost and operation difficulty.

[0021] Secondly, the traditional fixed mode has the problem of being not firm, for example, when a simple clip is used for fixing, the copper pipe is displaced due to vibration or movement in the detection process, affecting the accuracy of the detection result, and moreover, some traditional fixing methods are complex to operate, requiring multiple steps and great strength to complete the fixing, increasing the labor intensity and operation time of the workers, the above structure can generate a stable resistance force on the copper pipe under the action of the elastic extrusion piece on the threaded rotating block, the resistance force can be uniformly distributed on the circumferential surface of the copper pipe, ensuring that the copper pipe will not be displaced or shaken during the detection process, providing a stable basis for optical detection, ensuring the accuracy and reliability of the detection result, and the whole fixing structure is compact and integrated in the device, compared with the traditional device, the space is greatly saved, which makes the layout of the detection device on the production line more flexible, and the detection device can be conveniently used with other production equipment, improving the utilization rate of the production site.

[0037] The specific implementation of the present application is described in detail below in combination with specific examples.

[0038] The implementation example is as follows Figures 1 to 10 As shown in the drawings, the surface detection device for producing an environmentally friendly heat dissipation copper pipe provided by an embodiment of the present application comprises a detection platform 11, an optical capture machine 12, a first heat dissipation copper pipe 131, a second heat dissipation copper pipe 132, and a third heat dissipation copper pipe 133. The optical capture machine 12 is arranged on the top of the detection platform 11, and the first heat dissipation copper pipe 131, the second heat dissipation copper pipe 132, and the third heat dissipation copper pipe 133 are all arranged above the detection platform 11. The top of the detection platform 11 is provided with a turnover assembly for assisting the first heat dissipation copper pipe 131, the second heat dissipation copper pipe 132, and the third heat dissipation copper pipe 133 to rotate, and the upper part of the detection platform 11 is provided with a fixing assembly for fixing the first heat dissipation copper pipe 131, the second heat dissipation copper pipe 132, and the third heat dissipation copper pipe 133.

[0039] The turnover assembly comprises a positioning frame 21 fixedly connected to the top of the detection table 11, the top of the positioning frame 21 is fixedly connected with a driving device 22, the output shaft of the driving device 22 is fixedly connected with a power conversion disc 23, the outer wall of the power conversion disc 23 is fixedly connected with a rotating rod group 25 in an annular shape, and the top of the positioning frame 21 is fixedly connected with a gear disc 24.

[0040] The turnover assembly further comprises a square sliding groove 26, the square sliding groove 26 is arranged at the end of the rotating rod group 25 away from the power conversion disc 23, the inside of the square sliding groove 26 is slidably connected with a limiting sliding block 27, the inside of the limiting sliding block 27 is rotatably connected with a gear rod 29, the outer wall of the limiting sliding block 27 is fixedly connected with a return spring 28, one end of the return spring 28 away from the limiting sliding block 27 is fixedly connected to the rotating rod group 25, and the end of the rotating rod group 25 away from the power conversion disc 23 is fixedly connected with a buffer pad 210.

[0041] The fixing assembly comprises a fixing block 31 fixedly connected to the bottom of the gear disc 24, the bottom of the fixing block 31 is provided with a cylindrical fixed groove 32, and the bottom of the fixing block 31 is threadedly connected with a threaded rotating block 33.

[0042] The fixing assembly further comprises a communication groove 34 arranged in the inside of the threaded rotating block 33, the inner cavity of the fixing block 31 is fixedly connected with a limiting ring 35 at the top, and the bottom of the limiting ring 35 is fixedly connected with an elastic extrusion piece 36 in an annular distribution.

[0043] The buffer pad 210 is fixedly connected to the two sides of the return spring 28, so as to avoid that the limiting sliding block 27 abuts against the inner wall of the rotating rod group 25 and causes abrasion, and the gear rod 29 is engaged with the gear disc 24, so that the gear rod 29 rotates when sliding along the outer wall of the gear disc 24.

[0044] The communication groove 34 is in communication with the cylindrical fixed groove 32, so that the heat dissipation copper pipe can pass through the communication groove 34 and the cylindrical fixed groove 32 at the same time.

[0045] The top of the threaded rotating block 33 is provided in an inclined shape, the bottom of the elastic extrusion piece 36 is provided in an inclined shape, and the inclined surfaces of the threaded rotating block 33 and the elastic extrusion piece 36 are opposite to each other, so that after the threaded rotating block 33 is rotated in a forward direction, the threaded rotating block 33 will gradually tighten the elastic extrusion piece 36.

[0046] Working principle: in the initial state, the limiting sliding block 27 is located in the middle of the square sliding groove 26, the return spring 28 is compressed by the limiting sliding block 27 and the rotating rod group 25, and the inclined surfaces of the threaded rotating block 33 and the elastic extrusion piece 36 are abutted.

[0047] In work, the worker needs to fix the copper pipe first when detecting the surface of the copper pipe, and then reversely rotates the threaded rotating block 33, so that the threaded rotating block 33 rotates along the inside of the fixed block 31 and gradually descends, and then the threaded rotating block 33 gradually stops abutting the elastic pressing piece 36;

[0048] Since the communication groove 34 is communicated with the cylindrical fixed groove 32, the worker needs to pass the first copper pipe 131, the second copper pipe 132 and the third copper pipe 133 to be detected through the communication groove 34 and the bottom of the cylindrical fixed groove 32 in turn;

[0049] Then the worker rotates the threaded rotating block 33, so that the threaded rotating block 33 rotates along the inside of the fixed block 31 and gradually rises, since the top of the threaded rotating block 33 is provided in an inclined shape, the bottom of the elastic pressing piece 36 is provided in an inclined shape, and the inclined surfaces of the threaded rotating block 33 and the elastic pressing piece 36 are opposite, and in the process of rising of the threaded rotating block 33, the threaded rotating block 33 will abut the elastic pressing piece 36 and gradually tighten, so that the elastic pressing piece 36 gradually abuts the first copper pipe 131, the second copper pipe 132 and the third copper pipe 133, thereby achieving the purpose of fixing the copper pipe and fixing copper pipes of different sizes;

[0050] Compared with the traditional copper pipe surface detection device, the above structure can realize self-adaptive fixing of copper pipes of various sizes by rotating the threaded rotating block 33 to abut the inclined surface of the elastic pressing piece 36, so that the elastic pressing piece 36 can abut and fix copper pipes of different sizes. For example, when facing a copper pipe with a small diameter, the worker only needs to rotate the threaded rotating block 33, and the elastic pressing piece 36 can tightly abut the surface of the copper pipe. For a copper pipe with a large diameter, the worker continues to rotate the threaded rotating block 33, and the elastic pressing piece 36 will gradually tighten and always keep the copper pipe fixed effectively. This makes the detection device quickly and conveniently adapt to the detection needs of copper pipes of different sizes without the need for complex component replacement or adjustment process, greatly improving the versatility and production efficiency of the detection device, reducing production cost and operation difficulty;

[0051] Secondly, the above structure can generate a stable abutting force on the copper pipe under the action of the elastic pressing piece 36 on the threaded rotating block 33. This abutting force can be evenly distributed on the circumferential surface of the copper pipe, ensuring that the copper pipe will not shift or shake during detection, providing a stable basis for optical detection and ensuring the accuracy and reliability of the detection results. Moreover, the whole fixing structure is compact and integrated in the device, which greatly saves space compared with traditional devices. This makes the detection device more flexible in layout on the production line and can be easily used with other production equipment, improving the utilization rate of the production site.

[0052] After the first heat dissipation copper pipe 131, the second heat dissipation copper pipe 132, the third heat dissipation copper pipe 133 are fixed, the staff starts the driving device 22, makes the driving device 22 start and drive the power conversion disc 23 to rotate, and the power conversion disc 23 will drive the gear rod 29 to revolve around the positioning frame 21 through the rotating rod group 25 and the limiting slide block 27, so that the gear rod 29 drives the fixed block 31 at the bottom to revolve around the positioning frame 21 synchronously with the first heat dissipation copper pipe 131, the second heat dissipation copper pipe 132, the third heat dissipation copper pipe 133.

[0053] When the gear rod 29 revolves around the positioning frame 21, because the gear rod 29 is engaged with the gear disc 24, when the gear rod 29 slides along the outer wall of the gear disc 24, it will rotate, so that the gear rod 29 drives the fixed block 31 at the bottom to revolve around the positioning frame 21 synchronously with the first heat dissipation copper pipe 131, the second heat dissipation copper pipe 132, the third heat dissipation copper pipe 133 while rotating, so that the optical capture machine 12 can photograph the defects, defects or stains of the heat dissipation copper pipe, compared with the traditional heat dissipation copper pipe surface detection device, the above structure can make the optical capture machine 12 photograph the surface of the copper pipe from multiple angles, for example, when detecting a copper pipe with a curved shape, the rotation can ensure that each face of the curved part can be photographed, and the revolution further expands the coverage of the detection, greatly reduces the dead angle of the detection, significantly improves the comprehensiveness and accuracy of the detection, and better guarantees the product quality;

[0054] Secondly, when the rotating rod group 25 drives the gear rod 29 to engage with the gear disc 24, the limiting slide block 27 will slide along the inside of the square sliding groove 26 according to the shape of the gear disc 24, and the return spring 28 will always exert a force on the limiting slide block 27, so that the limiting slide block 27 limits the position of the gear rod 29 and the first heat dissipation copper pipe 131, the second heat dissipation copper pipe 132, the third heat dissipation copper pipe 133, thereby ensuring the stability of the rotation of the heat dissipation copper pipe driven by the gear rod 29, and after replacing the gear disc 24 of different shapes, the buffer pad 210 can reduce the friction of the limiting slide block 27 on the rotating rod group 25, thereby improving the service life of the equipment;

[0055] Compared with the traditional detection device, the above structure can change the shape of the gear disc 24 to make the gear rod 29 drive the heat dissipation copper pipe to move along a specific path, which provides great flexibility for detecting copper pipes of different shapes and specifications, for example, for some heat dissipation copper pipes with special curvature or special-shaped structure, by customizing the corresponding shape of the gear disc 24, the surface of the copper pipe can be easily and accurately detected without the need for large-scale modification of the entire detection device, improving the versatility and adaptability of the detection device, and better coping with complex and variable production tasks.
