[0042] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0043] Embodiment 1:

[0044] An integrated detection and conveying device for tubular parts, as Figure 1-7 shown, includes a base frame 1. A rotating seat is rotatably mounted on the base frame 1. A rotation driving part for driving the rotation of the rotating seat is mounted on the base frame 1. The rotating seat is provided with an inner support mechanism distributed circumferentially for supporting and fixing the tubular part 10. On the movement path of the inner support mechanism, a loading station, a detection station, a first unloading station and a second unloading station are arranged in sequence. Among them, the inner support mechanism includes:

[0045] A mounting seat 19, and the mounting seat 19 is mounted on the rotating seat;

[0046] A mounting column 23, one end of the mounting column 23 is rotatably mounted on the rotating seat, and the mounting column 23 and the mounting seat 19 are connected by a scroll spring 32;

[0047] An inner support assembly, and the inner support assembly is mounted on the mounting column 23;

[0048] The detection station is provided with a detection mechanism, and a flipping mechanism is arranged at the detection station. The flipping mechanism is used to drive the mounting column 23 to rotate to achieve comprehensive detection;

[0049] By arranging the inner support mechanism and the detection mechanism, the tubular part 10 can be mounted on the inner support structure. Based on the operation of the rotation driving part, the rotating seat is driven to rotate, and then the inner support structure is driven to move from the loading station to the detection station. During this period, based on the flipping of the flipping mechanism, the detection mechanism is used to comprehensively detect the tubular part 10.

[0050] In order to facilitate the flipping of the mounting column 23; as Figure 1 、 Figure 3 shown, the flipping mechanism includes a rubber disk 27, the rubber disk 27 is mounted on the mounting column 23, an arc-shaped rubber table 3 is mounted on the base frame 1, the arc-shaped rubber table 3 is located on the movement path of the rubber disk 27, and the arc-shaped rubber table 3 is adapted to the rubber disk 27;

[0051] By setting up a flipping mechanism, when the inner support mechanism passes by, the glue tray 27 can contact the arc-shaped glue table 3, and based on the frictional force, the mounting column 23 can be rotated to facilitate comprehensive detection.

[0052] Among them, the glue tray 27 can also be replaced with a helical gear, and the arc-shaped glue table 3 can be replaced with a matching arc-shaped rack, etc., which will not be elaborated here.

[0053] To facilitate driving the rotating seat to rotate; as Figure 2 shown, the rotation driving part includes a rotation driving motor 11, the rotation driving motor 11 is installed on the base frame 1, a driving gear 12 is installed at the output end of the rotation driving motor 11, a driven gear 8 is installed on the rotating seat, and the driving gear 12 meshes with the driven gear 8;

[0054] By setting up structures such as the rotation driving motor 11, based on the operation of the rotation driving motor 11, the driven gear 8 can be driven to rotate by the driving gear 12, thereby driving the rotating seat to rotate.

[0055] To facilitate detection; as Figure 2 shown, the detection mechanism includes:

[0056] A support frame 2, the support frame 2 is arranged on one side of the base frame 1;

[0057] An arc-shaped mounting plate 4, the arc-shaped mounting plate 4 is installed at one end of the support frame 2, and a plurality of laser detection components for detecting the outer surface of the tubular part 10 are arranged on the arc-shaped mounting plate 4, and the laser detection components are arranged in an arc distribution adapted to the movement path of the tubular part 10;

[0058] By setting up the detection mechanism, the surface of the tubular part 10 can be detected during the movement of the tubular part 10.

[0059] To facilitate supporting the tubular part 10; as Figure 3 、 Figure 4 shown, the inner support assembly includes:

[0060] A sliding cylinder 16, the sliding cylinder 16 is slidably connected to the outer wall of the mounting column 23, a sliding groove 17 is formed in the mounting column 23, a sliding block 26 slides in the sliding groove 17, the sliding block 26 is fixed in the sliding cylinder 16, and one end of the sliding block 26 close to the mounting seat 19 is connected to the mounting column 23 through a return spring;

[0061] A first support arm 13, one end of the first support arm 13 is hinged to the mounting column 23, and a plurality of first support arms 13 are arranged in a circumferential distribution around the mounting column 23;

[0062] The second arm 14, one end of the second arm 14 is hinged to the end of the first arm 13. The sliding cylinder 16 is divided into a first sliding cylinder and a second sliding cylinder. The first sliding cylinder and the second sliding cylinder are connected by a first spring 15. The other end of the second arm 14 is hinged to the first sliding cylinder. An anti-slip rubber block 24 is installed on the common hinge shaft of the first arm 13 and the second arm 14.

[0063] For reliable support; as Figure 1-5 shown, a circular frame 9 is fixed on the second sliding cylinder. An arc-shaped push plate 5 is arranged on the movement track of the circular frame 9. The arc-shaped push plate 5 is fixed on the base frame 1. The bottom of the mounting column 23 is fixed with a mounting frame 21. A movable plate 25 is slidably connected to the mounting frame 21. The movable plate 25 and the mounting frame 21 are connected by a spring column 31. The top of the movable plate 25 is provided with uniformly distributed first one-way limiting teeth 29. The bottom of the sliding cylinder 16 is provided with second one-way limiting teeth 30 that cooperate with the first one-way limiting teeth 29. The first one-way limiting teeth 29 and the second one-way limiting teeth 30 cooperate to realize the one-way limit of the movement of the sliding cylinder 16; that is: the sliding cylinder 16 is allowed to move away from the mounting seat 19.

[0064] During the process of the circular frame 9 moving from the feeding station to the detection station, the arc-shaped push plate 5 squeezes the circular frame 9 and pushes it away from the sliding cylinder 16, so that the sliding cylinder 16 moves unidirectionally outside the mounting column 23, thereby expanding the first arm 13 and the second arm 14, and using the inner side of the anti-slip rubber block 24 to support the inner wall of the tubular part. Since the first sliding cylinder and the second sliding cylinder are connected by the first spring 15, the reliability of the support is improved, and different sizes of tubular parts can be adapted.

[0065] For better feeding positioning; as Figure 3 shown, a limiting frame 18 is fixed on the mounting column 23. The limiting frame 18 is located on the side of the sliding cylinder 16 close to the mounting seat 19. A limiting plate 22 is fixed to the bottom of the mounting frame 21.

[0066] A loading platform 6 can also be arranged on one side of the base frame 1;

[0067] By setting structures such as the limiting plate 22, when installing the tubular part 10, its end can be made to abut against the limiting plate 22 to assist in positioning.

[0068] For better flipping and detection; as Figure 6 shown, a moving groove is formed in the mounting seat 19. A limiting block 28 is slidably connected in the moving groove. The limiting block 28 and the mounting seat 19 are connected by a second spring 34. A convex block 33 is arranged on the circumferential outer wall of the mounting column 23. The limiting block 28 is located on the movement path of the convex block 33;

[0069] By setting the limit block 28 and the convex block 33, the limit block 28 can be used to block the convex block 33 to ensure the consistency of the initial position of the mounting post 23. When the glue tray 27 rotates, the convex block 33 rotates and reaches the other side of the limit block 28. Since the limit block 28 itself has a thickness, when the convex block 33 rotates 360°, it pushes the limit block 28 and the second spring 34 compresses, ensuring that the mounting post 23 can rotate a complete circle. After the test is completed, the glue tray 27 is separated from the arc-shaped glue table 3, and based on the resilience of the scroll spring 32 and the second spring 34, the mounting post 23, the convex block 33 and the limit block 28 are driven to reset.

[0070] To facilitate unlocking the sliding cylinder 16; as Figure 1 、 Figure 5 、 Figure 7 shown, unlocking components are provided at both the first blanking station and the second blanking station. The unlocking components include:

[0071] An electric telescopic cylinder 35, which is installed on the base frame 1;

[0072] A lifting frame 37, which is fixed to the output end of the electric telescopic cylinder 35;

[0073] A guide plate 36, which is fixed to the outer wall of one side of the lifting frame 37. The bottom of the mounting frame 21 is provided with a ball head rod 20 through a bracket, and the ball head rod 20 is adapted to the guide plate 36;

[0074] By setting the unlocking component, after passing through the detection station, according to the detection situation of the product, the unlocking component at the first blanking station or the second blanking station can be controlled to work. Based on the electric telescopic cylinder 35, the lifting frame 37 is driven to move downward, and then the guide plate 36 is moved to the movement path of the ball head rod 20. After the ball head rod 20 passes, it is guided by the guide plate 36 to move downward, and then the first one-way limit teeth 29 and the second one-way limit teeth 30 on the mounting frame 21 are separated. Based on the return spring, the sliding cylinder 16 is driven to reset, and then the first arm 13 and the second arm 14 are reset, facilitating the separation of the tubular part 10;

[0075] In addition, structures such as an electric push plate can also be provided at the first blanking station and the second blanking station to assist the automatic separation of the tubular part 10, which will not be elaborated here.

[0076] To facilitate the collection of good products and defective products; as Figure 1 、 Figure 7 shown, receiving boxes 7 are provided at both the first blanking station and the second blanking station.

[0077] For the parts not exhaustively disclosed in the present invention, those skilled in the art can ensure the smooth implementation of the solution of the present invention based on common sense, normal thinking logic and existing technologies.

[0078] As described above, it is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
