It solves many problems associated with existing circular tube conveying methods used in medical device circular tube conveying. Common belt conveying methods are prone to slippage during conveying due to the smooth surface of the circular tube, leading to unstable conveying and difficulty in accurately controlling the conveying position of the circular tube, which affects the accuracy of subsequent opening processing. Some manual assisted conveying methods are not only inefficient and labor-intensive, but also prone to damage to the circular tube or conveying errors due to human factors, failing to meet the high efficiency and high precision requirements of modern medical device production.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a circular tube conveying device for medical device openings, comprising a support assembly, the main body of which is a U-shaped structure with a one-way opening at the top, and a guide rail mechanism fixedly connected to the outside of the support assembly, the guide rail mechanism being arranged longitudinally;

[0005] The guide rail mechanism has two locations, which are fixedly connected to the front and rear sides of the support assembly.

Two protruding slider assemblies are fixedly connected to the outside of the moving assembly. A rectangular plate baffle assembly is fixedly connected to the inside of the moving assembly. A pressure roller assembly is rotatably connected to the inside of the baffle assembly.

[0006] Preferably, a leg assembly is fixedly connected to the bottom surface of the support component. The leg assembly has a rectangular frame structure and there are two leg assemblies.

[0007] Preferably, the two support leg assemblies are fixedly connected in a linear array to the left and right sides of the bottom end face of the support assembly, and an installation assembly is fixedly connected to the front end face of the support assembly.

[0008] Preferably, a servo motor A is mounted on the right side of the mounting assembly, and a bevel gear A is mounted on the left output shaft of the servo motor A.

[0012] Beneficial effects

[0013] This invention provides a circular tube conveying device for the opening of medical devices. Compared with the prior art, it has the following advantages:

[0014] 1. In this utility model, by adopting a structure of support components, roller mechanism, conveyor belt and guide groove, a stable conveying function for medical device round tubes is achieved. Compared with the common belt conveying method, the V-shaped guide groove fits tightly with the round tube, effectively avoiding the slippage phenomenon caused by the smooth surface of the round tube, greatly improving the stability of the conveying, ensuring that the round tube can be accurately conveyed to the designated position, providing a reliable position guarantee for subsequent opening processing, and improving the accuracy of opening processing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a circular tube conveying device for opening medical devices, comprising: a support component 1, the main body of the support component 1 being a U-shaped structure with a one-way opening at the top, and a guide rail mechanism 3 fixedly connected to the outside of the support component 1, the guide rail mechanism 3 being arranged longitudinally;

[0025] There are two guide rail mechanisms 3, which are fixedly connected to the front and rear sides of the support assembly 1 in opposite directions. A support plate assembly 301 is fixedly connected to the top surface of each guide rail mechanism 3. A servo motor B3011 is mounted on the top surface of the support plate assembly 301. An output shaft is provided at the bottom end of the servo motor B3011. This output shaft is fitted with a lead screw transmission assembly 3012 via a coupling. A moving assembly 3013 is slidably connected inside the guide rail mechanism 3. The moving assembly 3013 has an opening that connects to the transmission assembly 3012. The moving component 3012 has a matching screw hole. The outer side of the moving component 3013 is fixedly connected to a slider assembly 3014 with two protruding structures. The inner side of the moving component 3013 is fixedly connected to a baffle assembly 3015 with a rectangular plate structure. The inner side of the baffle assembly 3015 is rotatably connected to a pressure roller assembly 3016. A conveyor belt 2011 is installed on the outer side of the roller mechanism 2. The outer side of the conveyor belt 2011 has a V-shaped guide groove 2012 with a linear array. The workpiece 2013 is installed inside the guide groove 2012.

[0026] Among them, a leg assembly 101 is fixedly connected to the bottom surface of the support assembly 1. The leg assembly 101 is a rectangular frame structure. There are two leg assemblies 101. The two leg assemblies 101 are fixedly connected to the left and right sides of the bottom surface of the support assembly 1 in a straight line array. An installation assembly 1011 is fixedly connected to the front surface of the support assembly 1.

[0027] The mounting component 1011 has a servo motor A1012 mounted on its right side, and a bevel gear A1013 mounted on the left output shaft of the servo motor A1012. The inner side of the support component 1 is rotatably connected to a roller mechanism 2. There are two roller mechanisms 2, which are arranged in a linear array and installed on the left and right sides inside the support component 1. The front end of the roller mechanism 2 located on the front side is coaxially mounted with a bevel gear B201, which meshes with the bevel gear A1013 for transmission.

[0028] During operation, first, place the round tube conveying device for the opening of the medical device in a suitable working position. The support leg assembly 101 provides stable support for the support assembly 1. Then, connect the power supply and start the servo motor A1012 and the servo motor B3011.

[0029] The left output shaft of the servo motor A1012 drives the bevel gear A1013 to rotate. Since the bevel gear A1013 meshes with the bevel gear B201, which is coaxially mounted at the front end of the front roller mechanism 2, the bevel gear B201 rotates accordingly, thereby driving the front roller mechanism 2 to rotate.

[0030] The conveyor belt 2011 installed on the outside of the roller mechanism 2 runs as the roller mechanism 2 rotates. The V-shaped guide grooves 2012 arranged in a straight array on the outside of the conveyor belt 2011 can fit closely with the workpiece 2013 (medical device tube) placed therein. Driven by the conveyor belt 2011, the tube is smoothly conveyed forward along the guide grooves 2012.

[0031] When the position of the round tube needs to be adjusted, such as adjusting the height or horizontal position of the round tube according to different requirements of subsequent opening processing, the servo motor B3011 is started. The output shaft at the bottom of the servo motor B3011 rotates through the lead screw structure transmission assembly 3012 assembled with the coupling. Since the moving assembly 3013 has a screw hole that matches the transmission assembly 3012 inside, and the slider assembly 3014 on its outer side slides inside the guide rail mechanism 3, the rotation of the transmission assembly 3012 will cause the moving assembly 3013 to move up and down along the guide rail mechanism 3. The baffle assembly 3015 fixedly connected to the inner side of the moving assembly 3013 and the pressure roller assembly 3016 rotatably connected to the inner side of the baffle assembly 3015 will move synchronously with the moving assembly 3013. The pressure roller assembly 3016 can play an auxiliary role in pressing and guiding the round tube during the movement, ensuring the stability of the round tube during the conveying process, and at the same time realizing the precise adjustment of the conveying position of the round tube.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
