Description

Technical Field

[0001] This utility model relates to the field of automated processing equipment technology, and in particular to an automatic CCD detection and flipping device for pipe products. Background Technology

[0002] In the manufacturing of tubular products, identifying the orientation of tubular materials with symmetrical appearance has long been a technical bottleneck. Thin-walled tubing, represented by aluminum tubing, is particularly difficult to identify due to the high symmetry of its inner and outer surfaces and the identical characteristics at both ends. Firstly, traditional optical inspection equipment struggles to penetrate the 0.4mm wall thickness to accurately capture internal rib features. Secondly, existing mechanical flaw detection devices can deform thin-walled tubing due to contact pressure. Furthermore, manual visual inspection and adjustment are not only labor-intensive and inefficient, but also highly susceptible to missed or misjudged inspections due to visual fatigue or negligence. Especially when tubing requires continuous multi-stage processing, incorrect orientation identification can directly lead to a shift in the processing baseline of subsequent stages, causing batch quality incidents.

[0003] In summary, for the automated processing of tubular products, there is currently a lack of integrated equipment on the market that can simultaneously achieve non-contact precision inspection, automatic orientation determination, and real-time correction. This severely restricts the automated production process of high-precision tubular products. Utility Model Content

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0049] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0050] In existing technologies, thin-walled tubes lack directional markings on their outer surface and have discontinuous rib structures inside, making it difficult for traditional inspection methods to penetrate the tube wall and identify internal features. Manual visual inspection suffers from low efficiency, high labor intensity, and a high risk of misjudgment, especially in continuous production scenarios, failing to meet the demands for high-precision, high-speed inspection. For example, on aluminum tube processing lines, operators need to use strong light to illuminate the inner wall of the tube to find the breakpoints of the ribs; this method is greatly affected by ambient light and easily causes visual fatigue.

[0051] To address the aforementioned issues, researchers observed a correlation between the location of the internal rib breakpoints of pipe 001 and the product orientation. However, the thin-walled structure prevented traditional vertical optical detection from penetrating the pipe wall. Through continuous research and analysis, it was discovered that obliquely incident light can directly reveal the location of the internal rib breakpoints of pipe 001. Based on this physical characteristic, this invention provides a CCD automatic detection and reversing device for pipe product orientation that can automatically, accurately, and efficiently detect concealed directional features inside pipe products, particularly the location of discontinuous rib breakpoints, and determine the orientation accordingly, as well as automatically flip the device.

[0052] In some embodiments, such as Figures 1 to 7 As shown, an automatic CCD detection and flipping device for pipe products is provided, including a base plate 100 and a feeding mechanism 200, a conveying mechanism 300 and a rotary table 400 mounted on the base plate 100. An angle dividing mechanism 500, a detection mechanism 600 and a flipping mechanism 700 are fixedly arranged above the rotary table 400, opposite to the feeding station, detection station and flipping station, and each station is arranged sequentially along its rotation direction.

[0053] The detection mechanism 600 is tilted downwards and faces the head of the aluminum tube 001 at the detection station. It is used to detect and determine whether the aluminum tube 001 is in the correct direction. In the subsequent flipping station, the flipping mechanism 700 flips and corrects the aluminum tube 001 with the wrong direction.

[0054] The base plate 100 is the foundation platform supporting all functional modules, which can be made of steel plate. Its function is to provide a stable installation reference for the feeding, handling, and rotating mechanisms. The feeding mechanism 200 is a material conveying device used to cut long aluminum tubes into aluminum tubes 001 of a preset length. It can use currently known cutting and conveying equipment, and its structure and working principle are existing technologies, which will not be described in detail here. Similarly, the handling mechanism 300 is a material transfer device, which can be a conventional robotic arm or a three-axis motion platform, used to transfer the aluminum tubes 001 from the feeding mechanism 200 to the rotary table 400.

[0055] The rotary table 400 serves as the circular motion platform for this device. Through an angle-splitting mechanism 500 and a controller 800, it controls intermittent rotation, enabling precise transfer of the aluminum tube 001 between the inspection station and the flipping station. The inspection mechanism 600 refers to the optical inspection component, including a CCD camera 601 and a third photoelectric sensor 602. Its tilted installation angle is calculated to directly illuminate the interior of the aluminum tube 001 and capture internal rib features. The flipping mechanism 700 is a direction correction device. A flipping motor 702 drives the gripping robot 701 to rotate 180°, used to correct the oriented errors of the aluminum tube 001.

[0056] Specifically, aluminum tubes 001 are arranged by the feeding mechanism 200 and then transferred by the conveying mechanism 300 to the loading station of the rotary table 400. The rotary table is controlled by the angle dividing mechanism 500 to rotate step by step, conveying the aluminum tubes 001 sequentially to the inspection station and the flipping station. At the inspection station, a CCD camera 601, installed at an angle, emits inspection light at a specific angle, directly hitting the inside of the aluminum tube and capturing the image features of the internal rib breakpoints. When an orientation error is detected, the rotary table 400 sends the aluminum tube 001 to the flipping station, where the flipping mechanism 700 performs a 180° rotation correction. The positions of each station are synchronized through photoelectric sensors to ensure the timing matching of the inspection and flipping actions.

[0057] Compared to traditional manual inspection methods that rely on operator experience and cannot operate continuously, this solution achieves unmanned operation by constructing an automated inspection-flipping system. The rotary table 400, the angle dividing mechanism 500, and the multi-station collaborative mechanism solve the problem of connecting inspection and execution processes, significantly improving processing efficiency.

[0058] The aforementioned CCD-based automatic inspection and flipping device for tubular products significantly improves the accuracy of identifying internal directional features in aluminum tube 001, avoiding missed detections caused by manual inspection. The automated integration of the inspection and flipping processes maintains stable production line speed and eliminates downtime caused by manual intervention. The design of the tilted optical inspection path overcomes the technical bottleneck of capturing internal features of thin-walled tubes, providing an effective solution for the automated inspection of similar products.

[0059] In some of these embodiments, such as Figures 1 to 7 As shown, to ensure the continuity and positional accuracy of the aluminum tube 001 from loading to inspection and flipping process, a feeding mechanism 200, a conveying mechanism 300, and a rotary table 400 are arranged sequentially from left to right on the base plate 100. The conveying mechanism 300 transports the aluminum tube 001 on the feeding mechanism 200 to the loading station of the rotary table 400. In this way, the linear control of the aluminum tube 001 conveying process is achieved through spatial layout optimization.

[0060] In some of these embodiments, such as Figure 1 , Figure 4 and Figure 6 As shown, to achieve intermittent and precise delivery of aluminum tube 001, the rotary worktable 400 includes a base 401, a fixed shaft 402, a synchronous pulley 403, and a rotating disk 404. The base 401 is fixedly installed on the right end of the base plate 100 by welding or bolt assembly, forming a stable support foundation and avoiding vibration or displacement during rotation.

[0061] A fixed shaft 402 is vertically mounted on the base 401 to provide a stable support foundation for the angle dividing mechanism 500, the detection mechanism 600, and the tilting mechanism 700. A synchronous pulley 403 is sleeved on the fixed shaft 402 via bearings, and its top is fixedly connected to the rotating disk 404. The drive motor is connected to the synchronous pulley 403 via a synchronous belt, which can directly control the start and stop angle of the rotating disk 404, thereby achieving precise intermittent conveying of the aluminum tube 001 between the feeding, detection, and tilting stations.

[0062] Furthermore, as one preferred embodiment, such as Figure 8 As shown, to ensure precise positioning and rapid, stable transfer of the aluminum tube 001 on the rotary table 400, several equidistantly spaced material seats 405 are arranged around the outer periphery of the rotary disk 404. Each material seat 405 has a vertically arranged positioning post 406 detachably mounted in the center. The aluminum tube 001 is vertically mounted on the positioning post 406, ensuring stability and preventing tipping. These equidistant material seats 405 and positioning posts 406 constitute different operating stations, achieving precise positional correspondence between the aluminum tube during rotation and the feeding, inspection, and flipping stations, ensuring the synchronization of actions at each station.

[0063] In some of these embodiments, such as Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in order to ensure the precise intermittent conveying and feeding coordination of aluminum tube 001 between various stations on the rotary worktable 400, an angle dividing mechanism 500 is provided. The angle dividing mechanism 500 mainly includes a first connecting plate 501 and a first photoelectric sensor 502. The precise positioning and synchronous conveying of aluminum tube 001 on the rotary worktable 400 are achieved by combining the structural layout of the first connecting plate 501 with the control of the first photoelectric sensor 502.

[0064] Specifically, one end of the first connecting plate 501 is fixedly mounted on the fixed shaft 402 in the middle of the rotary table 400, forming a stable mounting reference and avoiding interference with the sensor detection accuracy caused by vibration of the rotating disk. Two first photoelectric sensors 502 arranged vertically are fixedly mounted on the other end of the first connecting plate 501, and both first photoelectric sensors 502 are electrically connected to the controller 800.

[0065] Two first photoelectric sensors 502 are respectively arranged facing the upper and lower ends of the aluminum tube 001 at the feeding station. The dual-point detection eliminates the misjudgment that may be caused by the tilt of the aluminum tube 001 or surface reflection due to single-point detection. They are used to control the conveying mechanism 300 and the rotary table 404 to perform stepping actions through the controller 800, so as to realize the intermittent feeding of the aluminum tube 001 and its intermittent conveying in the circumferential direction.

[0066] In operation, when the aluminum tube 001 arrives at the loading station, the first photoelectric sensors 502, arranged vertically, simultaneously trigger signals. The controller 800 then synchronously controls the unloading action of the conveying mechanism 300 and the rotation angle of the rotary table 404, ensuring the aluminum tube 001 is accurately positioned in the material holder 405 of the rotary table 404. This design, through closed-loop control of photoelectric signals and mechanical motion, solves the problem of aluminum tube slippage or positional deviation caused by mismatched stepping timing in traditional manual operation, ensuring the reliability of subsequent inspection and flipping station processing.

[0067] Based on the above, such as Figure 3 , Figure 10 and Figure 8 As shown, to ensure the correct orientation of the flipped aluminum tube 001 is verified a second time and to avoid the risk of misjudgment of the orientation of the aluminum tube 001 after adjustment by the flipping mechanism 700, a second connecting plate 503 and a second photoelectric sensor 504 are also provided in the angle dividing mechanism 500. A closed-loop control mechanism for orientation verification is constructed through the second photoelectric sensor 504.

[0068] Specifically, one end of the second connecting plate 503 is rigidly connected to the fixed shaft 402 in the middle of the rotary table 400, and the other end is fixedly equipped with a second photoelectric sensor 504 to ensure the installation reference of the second photoelectric sensor 504 and avoid detection deviation caused by mechanical vibration or assembly error.

[0069] The second photoelectric sensor 504 takes the verification station downstream of the flipping station as the detection target. The second photoelectric sensor 504 is arranged towards the aluminum tube 001 located at the verification station downstream of the flipping station. Its arrangement direction forms a specific angular relationship with the head of the aluminum tube 001, which can capture the positional feature change of the head of the aluminum tube 001 after flipping, thereby detecting and judging whether the direction of the aluminum tube 001 after flipping is correct.

[0070] In use, when the aluminum tube 001 enters the verification station after being adjusted by the flipping mechanism 700, the second photoelectric sensor 504 feeds back the collected direction signal to the controller 800, forming a dual verification of the flipping action's execution effect. This design can not only identify potential operational failures of the flipping mechanism 700, such as loose clamping or flipping angle deviation, but also detect uncorrectable direction errors caused by structural abnormalities in the aluminum tube 007 itself, thus achieving a final determination of direction conformity before entering subsequent processes.

[0071] In some of these embodiments, such as Figure 6 , Figure 7 and Figure 8 As shown, to ensure the detection accuracy of the detection mechanism 600 in the direction of the aluminum tube head, the detection mechanism 600 adopts a combination of CCD camera 601 and third photoelectric sensor 602, both of which are electrically connected to the controller 800. Through the coordinated arrangement of CCD camera 601 and third photoelectric sensor 602, high-precision detection of the head direction features of aluminum tube 001 is achieved.

[0072] Specifically, the CCD camera 601 and the third photoelectric sensor 602 are tilted downwards and face the head of the aluminum tube 001 at the inspection station. The tilted downward inspection direction design enables the CCD camera 601 and the third photoelectric sensor 602 to effectively capture image information and position information of the end face of the aluminum tube 001, which is particularly suitable for identifying the hidden features of the internal rib break points.

[0073] Furthermore, addressing the challenges of inaccurate identification of hidden rib breakpoints inside aluminum tubes 001 of different specifications, and the inability to flexibly adjust the detection angle to align with the head of the aluminum tube 001, the CCD camera 601 and the third photoelectric sensor 602 are both mounted on the upper end of the support rod 604 via a universal adjustment bracket 603. The universal adjustment bracket 603 can be adjusted with multiple degrees of freedom according to the differences in aluminum tube specifications or detection requirements, ensuring that the optical detection equipment is always in the optimal observation position. The lower end of the support rod 604 is rigidly connected to the fixed shaft 402 on the rotary table 400, forming a stable detection reference coordinate system and avoiding detection errors caused by equipment vibration or displacement.

[0074] In some of these embodiments, such as Figure 8 , Figure 9 and Figure 10 As shown, to ensure the accuracy of the flipping action of aluminum tube 001 at the flipping station, the flipping mechanism 700 includes a gripping robot 701, a flipping motor 702, and a fourth photoelectric sensor 704. By using the gripping robot 701 in conjunction with the fourth photoelectric sensor 704 arranged in two positions, the directional flipping of aluminum tube 001 and the dual detection mechanism are realized.

[0075] Specifically, the gripping robot 701 is fixedly mounted on the output shaft of the flipping motor 702. The flipping motor 702 can drive the gripping robot 701 to achieve rotational freedom. The end of its robotic arm forms a dynamic gripping relationship with the aluminum tube 001, providing the basis for subsequent flipping actions.

[0076] As required, four photoelectric sensors 704 are fixedly installed above and below the gripping robot 701, with the two fourth photoelectric sensors 704 facing the upper and lower ends of the aluminum tube 001 at the flipping station, respectively, for secondary detection of whether the orientation of the aluminum tube 001 before flipping is incorrect. The symmetrically arranged fourth photoelectric sensors 704 form a spatial detection array, which can simultaneously capture the orientation feature signals of the upper and lower ends of the aluminum tube 001, and determine the correctness of the product orientation by comparing the differences between the two sensor signals.

[0077] Furthermore, such as Figure 8 and Figure 9As shown, to achieve stability in the vertical adjustment and installation of the flipping mechanism, the flipping mechanism 700 is also equipped with an L-shaped mounting plate 703, a lifting slide module 705, a triangular plate 706, and a third connecting plate 707. The flipping motor 702 and the fourth photoelectric sensor 704 are fixedly mounted on the horizontal plate of the L-shaped mounting plate 703, and its side plate is fixedly mounted on the slider of the lifting slide module 705. Through the structure of the horizontal plate and side plate of the L-shaped mounting plate 703, the flipping motor 702 and the fourth photoelectric sensor 704 are integrated on the horizontal plate. Simultaneously, the side plate is connected to the slider of the lifting slide module 705, thus achieving vertical height adjustability of the flipping mechanism 700.

[0078] The lifting slide module 705 is assembled on the third connecting plate 707 by a triangular plate 706. One end of the third connecting plate 707 is fixedly connected to the fixed shaft 402 on the rotary worktable 400, which not only ensures the rigid connection between the lifting slide module 705 and the fixed shaft 402, but also improves the overall support stability through the reinforcing structure of the triangular plate 706.

[0079] Furthermore, as in some of these embodiments, such as Figures 1 to 7 As shown, to ensure the accuracy of detection and flipping actions and the continuity of the automated process, and to improve the collaborative control performance of various mechanisms during direction detection and flipping, the device also includes a controller 800 fixedly installed on the front side of the base plate 100 for centralized control of various functional components. The controller 800 is connected to the drive motors and detection sensors on the feeding mechanism 200, the conveying mechanism 300, the rotary table 400, the angle dividing mechanism 500, the detection mechanism 600, and the flipping mechanism 700, respectively, thereby constructing a collaborative control link between the execution units and the detection units of the device.

[0080] The controller 800 used refers to an industrial control unit with multi-channel signal processing capabilities. Specifically, it can be implemented using a known PLC or embedded industrial computer, used to receive signals from various sensors and output drive commands. Electrical connection refers to establishing a control signal transmission link through a standard industrial communication interface, specifically using an RS485 bus or Ethernet protocol, to achieve real-time data interaction between the actuators and the controller.

[0081] Specifically, the start / stop signal of the feeding mechanism 200 is configured to receive pulse commands from the controller 800. The timing of the gripping action of the conveying mechanism 200 is synchronized with the indexing signal of the rotary table 400 by the controller 800. The stepping angle of the rotary table 400 is corrected in a closed loop by the controller 800 based on the photoelectric trigger signal of the angle division mechanism 500. The image acquisition command of the detection mechanism 600 and the rotary table station switching signal are synchronized at the millisecond level by the controller 800. The clamping action of the flipping mechanism 700 is configured to be triggered only when the CCD camera 601 and the fourth photoelectric sensor 602 confirm an incorrect orientation. The clamping force parameter is dynamically adjusted by the controller 800 through a preset threshold. The working status data of each execution unit is collected through the controller's built-in IO module to form an equipment operation log for anomaly tracing.
