Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a joint detection device and a blood tube production line. Background Art

[0002] Blood tubing is a tubing assembly used to carry blood in and out of the human body. It is a key component in establishing extracorporeal blood circulation during dialysis treatments and surgical procedures. During the blood tubing manufacturing process, multiple flexible tubes are connected via connectors to form a complete blood tubing system. Both the hoses and connectors are transparent, making it easy to observe the blood flow through them.

[0003] Whether the connector is properly assembled at the end of the hose directly affects the firmness of the hose and the connector. The blood tube assembly line is equipped with a connector inspection station for detecting whether the connector is in place to ensure that the connector assembly meets the requirements. In the connector inspection station, multiple hoses are arranged on the conveyor belt in sequence along the length of the conveyor belt. The connector inspection station is set on one side of the conveyor belt. The end of the hose with the connector is cantilevered and extends to the bottom of the camera of the connector inspection station. Since the connector is transparent, the depth of the hose inserted into the connector can be observed through the connector wall. Therefore, by using the camera to shoot the connector, the degree of installation of the connector can be detected. However, since the hose is relatively soft, the end of each hose with the connector will droop downward, and the degree of drooping of each hose is different, resulting in large fluctuations in the distance value between the camera and each connector. When the position of the connector deviates from the focal length range of the camera, the image taken by the camera will not be clear enough, affecting the accuracy of the detection result.

It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0034] The joint detection device of the present invention is used to detect the installation node of the hose 100 and the joint 200 on the blood tube production line. The blood tube production line includes a conveyor belt 300, and the hose 100 is arranged on the conveyor belt 300, and one end of the hose 100 equipped with the joint 200 is cantilevered and extends out of the conveyor belt 300. Figures 1 to 6 As shown, a preferred embodiment of the joint detection device of the present utility model includes:

[0035] Support frame 1, support frame 1 is arranged at intervals on one side of the conveyor belt 300;

[0036] The camera device 2 is disposed on the support frame 1 and is arranged vertically opposite to the joint 200;

[0037] The supporting member 3 is arranged on the side of the support frame 1 facing the conveyor belt 300;

[0038] The first driving device 4 is arranged on the support frame 1. The first driving device is used to drive the supporting member 3 to move upward so that the supporting member 3 lifts up the hose 100 near the joint 200; after shooting is completed, the first driving device 4 is also used to drive the supporting member 3 to move downward so that the supporting member 3 is separated from the hose 100.

[0039] Specifically, before the conveyor belt 300 moves the hose 100 to the supporting range of the supporting member 3, the supporting member 3 moves down to the lowest point. The conveyor belt 300 moves along the assembly line direction and moves the hose 100 above the supporting member 3. The first drive device drives the supporting member 3 to move upward, so that the supporting member 3 lifts up the hose 100 near the joint 200, thereby lifting the joint 200 connected to the end of the hose 100, avoiding the joint 200 from sagging and being out of the focal range of the camera, thereby ensuring the clarity of the captured picture; after the shooting is completed, the first drive device 4 drives the supporting member 3 to move downward, so that the supporting member 3 is separated from the hose 100, and then the conveyor belt 300 drives the hose 100 to move out of the supporting range of the supporting member 3. Therefore, when the hose 100 follows the conveyor belt 300 and moves horizontally along the assembly line into the supporting range of the supporting member 3, or when it moves out of the supporting range of the supporting member 3, it will not touch the supporting member 3. Therefore, no horizontal friction will occur between the hose 100 and the supporting member 3, thereby preventing the hose 100 from being scratched by the supporting member 3 due to horizontal movement between the hose 100 and the supporting member 3.

[0040] Among them, in order to maintain the stability of the connector 200 during the detection process and avoid the connector 200 deviating upward due to the upward warping of the part of the hose 100 close to the connector 200, in this embodiment, the connector detection device includes a downward pressure member 5 and a second driving device 6, the downward pressure member 5 and the supporting member 3 are arranged relatively spaced apart above and below, and the second driving device 6 is set on the support frame 1; when the first driving device 4 drives the supporting member 3 to move upward, the second driving device 6 drives the downward pressure member 5 to move downward, so that the downward pressure member 5 and the supporting member 3 clamp the hose 100; when the first driving device 4 drives the supporting member 3 to move downward, the second driving device 6 drives the downward pressure member 5 to move upward, so that the downward pressure member 5 is separated from the hose 100.

[0041] Specifically, the supporting member 3 and the pressing member 5 form a clamping mechanism that can move closer or further away from the rear. During the movement of the conveyor belt 300, the clamping mechanism is in a loosened state to prevent the supporting member 3 and the pressing member 5 from contacting the hose 100 and causing scratches on the hose 100. After the conveyor belt 300 moves the hose 100 above the supporting member 3, the clamping mechanism switches to a clamping state to prevent the joint 200 from swinging up or down due to the upward or downward warping of the hose 100, and ensures that the joint 200 remains stable during shooting, further ensuring the shooting quality of the camera.

[0042] In this embodiment, a first positioning groove 321 with an upward opening is provided at a position where the supporting member 3 is opposite to the hose 100, and first guide surfaces for guiding the hose 100 to the center of the first positioning groove 321 are symmetrically provided on both sides of the first positioning groove 321; a first positioning protrusion 521 for matching and inserting into the first positioning groove 321 is provided at a position where the pressing member 5 is opposite to the first positioning groove 321 in upper and lower directions.

[0043] Specifically, the first guide surfaces on either side of the first positioning groove 321 can guide the hose 100, which is horizontally tilted toward the front or rear of the conveyor belt 300, to a position perpendicular to the conveyor belt 300, thereby ensuring that the connector 200 is always within the camera's field of view during video recording, further ensuring video quality. In this embodiment, the first positioning groove 321 is a V-shaped groove, and both the first and second guide surfaces are inclined surfaces. In other embodiments of the present invention, the first positioning groove 321 can be an isosceles trapezoidal, semicircular, or semi-elliptical shape. When the first positioning groove 321 is semicircular or semi-elliptical, the first guide surfaces are curved.

[0044] Furthermore, a first semicircular groove 5211 is provided at the bottom of the first positioning protrusion 521 for retaining the hose 100, and a second semicircular groove 3211 is provided at the bottom of the first positioning groove 321 for retaining the hose 100. Specifically, when the supporting member 3 and the pressing member 5 are closed under the action of the first driving device 4 and the second driving device 6, respectively, the first positioning groove 321 guides the hose 100 to the middle of the first positioning groove 321, and the lower half of the hose 100 slides into the second semicircular groove 3211, and the upper half of the hose 100 slides into the second semicircular groove 3211. The provision of the first semicircular groove 5211 and the second semicircular groove 3211 can prevent the hose 100 from being crushed due to the supporting member 3 and the pressing member 5 being too close.

[0045] In this embodiment, Figures 4 to 6 As shown, the supporting member 3 includes a first plate 31 and a second plate 32 stacked in a direction from the conveyor belt 300 to the support frame 1, and the pressing member 5 includes a third plate 51 arranged vertically opposite to the first plate 31 and a fourth plate 52 arranged vertically opposite to the second plate 32;

[0046] The first positioning groove 321 is provided at the upper end of the second plate 32 , and the first positioning protrusion 521 is provided at the lower end of the fourth plate 52 ;

[0047] A second positioning groove 511 with an opening facing downward is provided at the position where the third plate 51 is opposite to the hose 100, and second guide surfaces for guiding the hose 100 to the center of the second positioning groove 511 are symmetrically provided on both sides of the second positioning groove 511; a second positioning protrusion 311 for matching and inserting into the second positioning groove 511 is provided at the position where the first plate 31 is opposite to the second positioning groove 511 in the upper and lower directions.

[0048] Specifically, the third plates 51 and second plates 32 are arranged vertically in an alternating pattern, while the fourth plates 52 and first plates 31 are arranged vertically in an alternating pattern. The first positioning grooves 321 and second positioning grooves 511 are arranged vertically in an alternating pattern. The first positioning grooves 321 and second positioning grooves 511 align the hose 100, further ensuring the stability of the connector 200 after being clamped by the support member 3 and the pressing member 5. In this embodiment, multiple sets of first plates 31 and second plates 32 can be provided, as can multiple sets of third plates 51 and fourth plates 52.

[0049] Furthermore, a third semicircular groove 3111 for clamping the hose 100 is provided at the top of the second positioning protrusion 311 , and a fourth semicircular groove 5111 for clamping the hose 100 is provided at the bottom of the second positioning groove 511 .

[0050] In this embodiment, the joint detection device includes a first mounting plate 11 disposed on a side of the support frame 1 near the conveyor belt 300. The camera device 2 is disposed at the upper end of the first mounting plate 11. The lower end of the first mounting plate 11 is connected to a background plate 7. The background plate 7 is located below the hose 100, and the camera device 2 and the background plate 7 are arranged vertically opposite each other. The provision of the background plate 7 helps maintain a uniform background for the captured images, preventing any cluttered lines in the background from interfering with the captured images.

[0051] Furthermore, the joint detection device includes a second mounting plate 12, which is provided with a vertically extending slot 121. A fastening assembly is connected to the first mounting plate 11 and is inserted into the slot 121. The camera device 2 is connected to the second mounting plate 12. After loosening the fasteners, the first mounting plate 11 can be slid up and down to adjust the height of the camera, thereby adjusting the distance between the camera and the joint 200. After the camera is in the correct position, the fasteners can be tightened to fix the camera position.

[0052] Furthermore, the support frame 1 is provided with a slide rail 13 arranged along the length direction of the conveyor belt 300, the slide rail 13 is connected to the slider 14, the first mounting plate 11 is fixedly connected to the slider 14, and the support frame 1 is fixed with a third driving device 8 for driving the slider 14 to move.

[0053] Specifically, the slider 14 is driven to move by the third driving device 8 , which can drive the camera to move along the length direction of the conveyor belt 300 , thereby moving the camera to each joint 200 in turn to achieve detection of multiple joints 200 .

[0054] In this embodiment, the third drive device 8 can be a screw slider 14 mechanism or a linear guide. In this embodiment, the first drive device 4 and the second drive device 6 are both pneumatic cylinders. In other embodiments of the present invention, the first drive device 4 and the second drive device 6 can be hydraulic cylinders, electric push rods, or linear guides.

[0055] In summary, the joint detection device of the present invention is used to detect the installation node of the hose 100 and the joint 200 on the blood tube production line, including a support frame 1, a camera device 2, a supporting member 3 and a first driving device 4. The support frame 1 is arranged at intervals on one side of the conveyor belt 300, the camera device 2 is arranged on the support frame 1 and arranged relative to the joint 200, the supporting member 3 is arranged on the side of the support frame 1 facing the conveyor belt 300, and the first driving device 4 is arranged on the support frame 1. The first driving device drives the supporting member 3 to move upward, so that the supporting member 3 can be lifted up close to the joint 200. The hose 100 is lifted, thereby supporting the connector 200 connected to the end of the hose 100, preventing the connector 200 from sagging and being out of the focal range of the camera, thereby ensuring the clarity of the captured picture; after the shooting is completed, the first driving device 4 drives the supporting member 3 to move downward, so that the supporting member 3 is separated from the hose 100, and then the conveyor belt 300 drives the hose 100 to move out of the supporting range of the supporting member 3. Therefore, the hose 100 will not touch the supporting member 3 when following the conveyor belt 300 to move horizontally along the assembly line, thereby preventing the hose 100 from being scratched by the supporting member 3 due to horizontal movement between the supporting member 3.

[0056] An embodiment of a blood tube production line includes the above-mentioned connector detection device.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
