Description

Technical Field

[0001] This invention relates to the field of medical device manufacturing equipment technology, specifically an automatic conveying device for a syringe production line. Background Technology

[0002] As one of the most basic drug delivery tools in clinical medicine, syringes are increasingly in demand in the medical industry, and with ever-increasing product quality requirements, the degree of automation in syringe production lines has become a key factor determining production efficiency and product quality. In automated syringe production lines, the conveying device plays a crucial role in transferring syringes or semi-finished syringes between different processes, acting as a bridge connecting each production stage. However, existing syringe conveying devices still have the following shortcomings:

[0003] First, syringe barrels or semi-finished syringes are prone to axial movement and radial deflection during transport. Syringes have a slender structure and uneven center of gravity distribution. Driven by the conveyor belt, especially during acceleration, deceleration, or when passing through conveyor belt seams, they are highly susceptible to rolling, skewing, or shifting, causing the syringe barrel to deviate from its intended transport posture.

[0004] Secondly, existing conveying devices mostly use straight conveyor belts or chain structures as the conveyor carrier. The syringes are only roughly constrained by side limiting plates on the conveyor belt, lacking precise control over their axial position. When the syringe enters the conveying mechanism through the inlet, it's difficult to ensure that the syringe enters the conveyor belt in a flat position, leading to deviations in the position of the limiting plates, especially during the transfer between two different batches of syringes. Furthermore, when multiple syringes are on the conveyor line simultaneously, it's difficult to maintain consistent spacing between them, resulting in a messy conveying process and affecting syringe delivery efficiency.

[0005] In summary, there is a need for an automated conveying device for syringe production lines that can stably constrain the posture of syringes throughout the entire conveying process, achieving buffered introduction and precise spacing maintenance. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic conveying device for a syringe production line, which can stably constrain the posture of syringes throughout the conveying process, and achieve buffered introduction and precise spacing maintenance.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The device includes a main body, an adjusting mechanism, and a conveying mechanism. The adjusting mechanism includes a support platform and an air-float platform. The support platform is equipped with a servo motor, and the output end of the servo motor is equipped with an elastic scraper. A support rod is located on the side of the support platform near the conveying mechanism, and an electric push rod is located on the side of the support platform near the support rod. The output end of the electric push rod is equipped with an adjusting baffle. The support rod is equipped with a vision sensor. The conveying mechanism includes a limiting component and a second conveying platform. The main body of the device has a feeding mechanism, an adjusting mechanism, and a conveying mechanism arranged along the movement direction of the syringe. The feeding mechanism conveys the syringes to the adjusting mechanism in an orderly manner through the feeding port and the limiting groove. The adjusting mechanism adjusts the position of the syringes conveyed from the feeding mechanism through the air-float platform and the elastic scraper, from the discharge port to the limiting component of the conveying mechanism (the discharge port is not marked in the figure). The limiting component provides stable support for the syringes during the conveying process.

[0009] During operation, when the syringe is conveyed from the feeding mechanism to the adjusting mechanism via the first conveyor, the air flotation platform provides stable airflow support to the syringe through the ventilation micro-holes, causing the syringe to float slightly. The servo motor drives the elastic scraper at its output end to rotate. In this embodiment, there are 1 elastic scraper, and the included angle between two adjacent elastic scraper supports is 60° to adapt to the conveying efficiency of the feeding mechanism. One elastic scraper gently pushes one syringe, conveying the syringes in an orderly manner. At this time, the elastic scraper gently pushes the syringe to move towards the support rod. The vision sensor set in the middle of the support rod measures the length and position of the syringe. Through two electric push rods, the adjusting baffles on both sides of the support rod are extended and retracted to adjust the posture of the syringe, moving the syringe to the center of the adjusting baffle in a flat posture. At the same time, it adapts to different models of syringes. Finally, it moves from the discharge port to the conveying mechanism. The middle section of the discharge port is set to be arc-shaped, and the outlet section is set to be horizontal, so that the syringe can fall smoothly into the arc-shaped groove.

[0010] Specifically, a support rod is fixedly installed on the side of the support platform near the delivery mechanism, spanning across the end of the air flotation platform. A vision sensor is fixedly installed at the center of the crossbeam of the support rod, with the imaging area covering the syringe between the end of the air flotation platform and the adjusting baffle. The vision sensor can be a CCD smart camera with built-in image processing algorithms, capable of measuring the length, position, and axial deflection angle of the syringe in real time. On the side of the support platform near the support rod, i.e., on both sides of the support rod, there is an electric push rod. The electric push rods are horizontally opposite each other, with their cylinders fixed to the support platform and their output ends facing the centerline of the syringe channel. Adjusting baffles are fixedly connected to the output ends of the two electric push rods. The adjusting baffles are long, thin strips located on both sides above the air flotation platform, with their opposing inner surfaces forming the guide channel for the syringe. The openings of the opposing surfaces of the two adjusting baffles gradually decrease along the delivery direction of the syringe, forming a funnel-shaped tapering channel, facilitating the smooth introduction and centering of the syringe with the help of the elastic scraper.

[0011] Preferably, the limiting component includes a slide groove and a base. The slide groove is provided with a slider. Each limiting component is provided with two slide grooves, a base, a slider, and a spring. The two slide grooves, bases, sliders, and springs are all provided on both sides of the arc-shaped groove.

[0012] Preferably, the slider fits against both sides of the groove, the slider is connected to one end of the spring, and the other end of the spring is connected to the base. The two sliders are arranged opposite each other, and the opposite surfaces of the sliders are inclined, forming a certain angle. When the syringe travels from the outlet to the conveying mechanism, it first reaches between the two sliders, and under the action of gravity and inertia, overcomes the spring force to enter the arc-shaped groove.

[0013] Preferably, the second conveying table is provided with an arc-shaped groove along the direction of syringe movement. The arc surface of the arc-shaped groove is tangent to the contact surface of the syringe. Two limiting components are provided at both ends of the same arc-shaped groove and in the conveying direction perpendicular to the syringe. The two limiting components fix the two ends of the syringe.

[0014] Specifically, the syringe falls smoothly from the adjustment mechanism through the discharge port into the conveying mechanism, between the two chutes. Under the action of the syringe's own weight and inertia, the two sliders overcome the spring force and move back to back along the chutes. The syringe moves downward to the arc-shaped groove, and the spring pushes the two sliders to move towards each other, clamping the two ends of the syringe and enabling stable transport of the syringe.

[0015] Preferably, the air flotation platform is provided with ventilation micro-holes, which are arranged along the movement direction of the syringe. The air flotation platform is equipped with an air compressor, an air tank and a control valve to achieve stable airflow. This is not shown in the figure. The air flotation platform allows the syringe to be slightly suspended, reducing the frictional resistance of the syringe and facilitating the movement and posture adjustment of the syringe under the action of the elastic scraper.

[0016] Preferably, the feeding end of the main body of the device is provided with a feeding mechanism, which completes the initial sorting and feeding of the syringes.

[0017] Preferably, a feeding buffer platform is provided on the side of the feeding mechanism away from the adjusting mechanism. The surface of the feeding buffer platform has a certain slope, that is, the slope increases along the direction of movement of the syringe. The feeding buffer platform is provided with a feeding port, and the structure of the feeding port is similar to that of the discharging port, and is set as an arc structure.

[0018] Preferably, the feeding mechanism is provided with a first conveyor table, and the first conveyor table is provided with a limiting groove along the movement direction of the syringe. The syringe is placed on the buffer table, passes through the inlet and outlet to the limiting groove on the first conveyor table, and is conveyed to the adjustment mechanism.

[0019] Preferably, there are two electric push rods, and each of the two electric push rods has an adjusting baffle at its output end. The opening of the adjusting baffle gradually decreases along the delivery direction of the syringe, which facilitates the introduction of the syringe with the elastic scraper.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This device integrates a vision sensor, electric push rods, and adjusting baffles through a feeding mechanism and an adjusting mechanism, achieving orderly conveying and automatic posture adjustment. The vision sensor on the support rod can measure the actual length and positional deviation of each syringe in real time. The control system controls the extension and retraction of two electric push rods based on the measurement data, thereby dynamically adjusting the spacing and angle of the adjusting baffles to guide the syringes to center and straighten. This achieves syringe posture adjustment, facilitating the precise placement of syringes into the clamping assembly and ensuring stable subsequent conveying.

[0022] 2. An arc-shaped groove is set on the second conveyor platform of the conveying mechanism. The groove surface is tangent to the outer circle of the syringe, providing a close-fitting surface support. Simultaneously, limiting components are set at both ends of the arc-shaped groove. Using a slider that moves obliquely along the groove, the syringe is actively clamped from both ends under the elastic force of a spring. When the syringe falls from the outlet, its own weight and inertia automatically push the slider open and allow it to fall into the arc-shaped groove. The spring then automatically returns to its original position and clamps the syringe, eliminating the need for additional active drive components. This double-end elastic clamping method effectively prevents the syringe from tilting and jumping during high-speed start-stop or turning conveying processes, ensuring the positioning accuracy of subsequent processes.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: As Figure 1 As shown, the present invention provides an automatic conveying device for a syringe production line.

[0033] The main body 1 of the device is an integral frame, serving as the mounting base for all components. A feed inlet 211 is fixedly installed at the feeding end of the main body 1. The feed inlet 211 is an open-top, tapering-bottom discharge structure with a smooth-transitioning funnel-shaped inner wall, allowing direct connection to the discharge port of the previous process. The lower outlet of the feed inlet 211 faces the starting end of the first conveyor table 22, ensuring that the syringes falling from above accurately land on the bearing surface of the first conveyor table 22. The second conveyor table 42 employs a chain plate or synchronous belt structure that runs synchronously with the first conveyor table 22. Multiple arc-shaped grooves 421 are evenly spaced along the conveying direction on its bearing surface. The groove surfaces of the arc-shaped grooves 421 are circular arc-shaped. During operation, the syringes pass through the feed inlet 211 and land on the flat belt surface of the first conveyor table 22. The first conveyor table 22 uses friction to transport the syringes forward. Upon reaching the end, the syringes are smoothly transferred into the corresponding arc-shaped grooves 421 on the second conveyor table 42 under the action of inertia and belt thrust. After the syringe falls into the arc-shaped groove 421, it maintains a stable posture under the support of the arc surface and moves forward with the second conveyor table 42 until it is delivered to the target station.

[0034] Example 2: Figures 1-7 As shown, the present invention provides an automatic conveying device for a syringe production line.

[0035] The device includes a main body 1, an adjustment mechanism 3, and a conveying mechanism 4. The adjustment mechanism 3 includes a support platform 31 and an air flotation platform 34. The support platform 31 is equipped with a servo motor 33, and the output end of the servo motor 33 is equipped with an elastic scraper 32. A support rod 35 is provided on the side of the support platform 31 near the conveying mechanism 4. An electric push rod 37 is provided on the side of the support platform 31 near the support rod 35. An adjustment baffle 36 is provided on the output end of the electric push rod 37. A vision sensor 38 is provided on the support rod 35. The conveying mechanism 4 includes a limiting component 41 and a second conveying platform 42. The main body 1 of the device is provided with a feeding mechanism 2, an adjusting mechanism 3 and a conveying mechanism 4 along the direction of movement of the syringe. The feeding mechanism 2 conveys the syringe to the adjusting mechanism 3 in an orderly manner through the feeding port 211 and the limiting groove 221. The adjusting mechanism 3 adjusts the position of the syringe conveyed from the feeding mechanism 2 through the air flotation platform 34 and the elastic scraper 32. The syringe is moved from the discharge port to the limiting component 41 of the conveying mechanism 4. The discharge port is not marked in the figure. The limiting component 41 provides stable support for the syringe during the conveying process.

[0036] A servo motor 33 is also fixedly installed on the support platform 31. The servo motor 33 is located on one side of the air flotation platform 34, and its output shaft is arranged vertically upward. An elastic scraper 32 is fixed at the top of the output shaft. In this embodiment, six elastic scrapers 32 are provided, distributed at equal angles around the output shaft axis, with an included angle of 60° between adjacent elastic scrapers 32 to match the conveying efficiency of the feeding mechanism 2. Each elastic scraper 32 consists of a fixed root section and an elastic actuating end section, possessing good elastic recovery capability. When the servo motor 33 drives the output shaft to rotate, the elastic scrapers 32 sequentially rotate into the working area, and their ends can gently actuate the syringes suspended on the air flotation platform 34, achieving orderly pushing of individual syringes. The elastic scraper 32 undergoes elastic bending deformation upon contact with the syringe, providing sufficient pushing force while avoiding scratching the syringe surface, and adapting to syringes of different diameters.

[0037] During operation, when the syringe is conveyed from the feeding mechanism 2 to the adjusting mechanism 3 via the first conveyor 22, the air flotation platform 34 provides stable airflow support to the syringe through the ventilation micro-holes 341, causing the syringe to float slightly and reducing the friction of the syringe. This allows the elastic scraper 32 to move the syringe with force, preventing friction damage to the syringe. The servo motor 33 drives the elastic scraper 32 at its output end to rotate to adapt to the conveying efficiency of the feeding mechanism 2. One elastic scraper 32 gently moves one syringe, conveying the syringes in an orderly manner. At this time, the elastic scraper 32 gently moves the syringe towards the support rod 35. The vision sensor 38 set in the middle of the support rod 35 measures the length and position of the syringe. Through two electric push rods 37, the adjusting baffles 36 on both sides of the support rod 35 are extended and retracted to adjust the posture of the syringe, moving the syringe in a flat posture towards the center of the adjusting baffle 36. This accommodates different types of syringes. Finally, the syringe moves from the outlet to the conveying mechanism 4. The middle section of the outlet is set to be arc-shaped, and the outlet section is set to be horizontal, which facilitates the syringe falling smoothly into the arc-shaped groove 421.

[0038] Specifically, a support rod 35 is fixedly installed on the side of the support platform 31 near the delivery mechanism 4, spanning above the end of the air flotation platform 34. A vision sensor 38 is fixedly installed at the center of the crossbeam of the support rod 35, and the imaging area covers the syringe between the end of the air flotation platform 34 and the adjusting baffle 36. The vision sensor 38 is preferably a CCD smart camera with built-in image processing algorithms, capable of measuring the length, position, and axial deflection angle of the syringe in real time. An electric push rod 37 is installed on each side of the support platform 31 near the support rod 35. The electric push rods 37 are arranged horizontally opposite each other, with their cylinders fixed on the support platform 31 and their output ends facing the center line of the syringe channel. The output ends of the two electric push rods 37 are respectively fixedly connected to the adjusting baffle 36. The adjusting baffle 36 is a long strip of thin plate, located on both sides above the air flotation platform 34, and its opposing inner surfaces form the guide channel for the syringe. The openings of the two adjusting baffles 36 gradually decrease along the delivery direction of the syringe, forming a trumpet-shaped tapering channel, which facilitates the smooth introduction and concentration of the syringe with the elastic scraper 32.

[0039] Preferably, the limiting component 41 includes a slide groove 413 and a base 414. The slide groove 413 is provided with a slider 412. Each limiting component 41 is provided with two slide grooves 413, bases 414, sliders 412 and springs 411. The two slide grooves 413, bases 414, sliders 412 and springs 411 are all provided on both sides of the arc-shaped groove 421.

[0040] Preferably, the slider 412 is fitted to both sides of the groove 413, and one end of the slider 412 is connected to the spring 411, while the other end of the spring 411 is connected to the base 414. The two sliders 412 are arranged opposite each other, and the opposite surfaces of the sliders 412 are inclined, forming a certain angle. When the syringe travels from the outlet to the conveying mechanism 4, it first reaches between the two sliders 412, and under the action of gravity and inertia, overcomes the elastic force of the spring 411 and enters the arc-shaped groove 421.

[0041] Preferably, the second delivery table 42 is provided with an arc-shaped groove 421 along the direction of syringe movement. The arc surface of the arc-shaped groove 421 is tangent to the contact surface of the syringe. Two limiting components 41 are provided at both ends of the same arc-shaped groove 421 and perpendicular to the delivery direction of the syringe. The two limiting components 41 fix the two ends of the syringe. The limiting component 41 specifically includes a slide 413, a base 414, a slider 412, and a spring 411. Each limiting component 41 is provided with two slides 413, two bases 414, two sliders 412, and two springs 411, and the two slides 413, two bases 414, two sliders 412, and two springs 411 are respectively provided on both sides of the arc-shaped groove 421. The two sliders 412 are arranged opposite each other, and the inner side of each slider 412 facing the syringe is inclined, so that the two opposing inclined surfaces form a guide space that is wider at the top and narrower at the bottom, which can form a certain angle. The base 414 is fixed to the outer upper end of the slide groove 413, serving as the fixed end of the spring 411. The slider 412 is embedded in the channel of the slide groove 413, and its two sides slide against the side walls of the slide groove 413, allowing the slider 412 to slide back and forth only along the slide groove 413. One end of the spring 411 is connected to the tail of the slider 412, and the other end is connected to the base 414. The preload of the spring 411 pushes the slider 412 toward the direction of the syringe.

[0042] Specifically, the syringe falls smoothly from the adjustment mechanism 3 through the discharge port into the conveying mechanism 4, between the two chutes 413. Under the action of the syringe's own weight and inertia, the two sliders 412 overcome the elastic force of the spring 411 and move in opposite directions along the chutes 413. The syringe moves downward to the arc-shaped groove 421, and the spring 411 pushes the two sliders 412 to move towards each other, clamping the two ends of the syringe and enabling the syringe to be transported stably.

[0043] Preferably, the air flotation platform 34 is provided with ventilation micro-holes 341, which are arranged along the moving direction of the syringe. The air flotation platform 34 is equipped with an air compressor, an air tank and a control valve to achieve stable airflow in the air flotation platform 34 (not shown in the figure), so that the syringe is slightly suspended, reducing the frictional resistance of the syringe and facilitating the movement and posture adjustment of the syringe under the action of the elastic scraper 32.

[0044] Preferably, the feeding end of the main body 1 of the device is provided with a feeding mechanism 2, which completes the initial sorting and feeding of the syringes.

[0045] Preferably, a feeding buffer platform 21 is provided on the side of the feeding mechanism 2 away from the adjusting mechanism 3. The surface of the feeding buffer platform 21 has a certain slope, that is, the slope increases along the direction of movement of the syringe. The feeding buffer platform 21 is provided with a feeding port 211. The structure of the feeding port 211 is similar to that of the discharge port and is set as an arc structure.

[0046] Preferably, the feeding mechanism 2 is provided with a first conveyor platform 22. The first conveyor platform 22 is provided with limiting grooves 221 along the direction of syringe movement. The syringe is placed on the feeding buffer platform 21, passes through the feed inlet 211 to the limiting grooves 221 on the first conveyor platform 22, and is then conveyed to the adjusting mechanism 3. Specifically, the feeding mechanism 2 is located at the feeding end of the main body 1 of the device, and includes a feeding buffer platform 21 and a first conveyor platform 22. The feeding buffer platform 21 is a rectangular platform with an inclined surface. The platform has a gradually increasing slope along the direction of syringe movement, preferably 5°-10°, so that the syringe can slide in the conveying direction under its own weight. The feed inlet 211 has an arc-shaped guide groove structure. The arc structure can guide the syringe to automatically adjust to a state where its axis is consistent with the conveying direction during the sliding process, and drop into the first conveyor platform 22 one by one. The first conveyor platform 22 is arranged along the direction of syringe movement, and multiple limiting grooves 221 are fixed at equal intervals on the belt. The cross-section of the limiting groove 221 is an arc-shaped groove that matches the outer contour of the syringe, and the spacing between adjacent limiting grooves 221 matches the processing cycle of the subsequent adjustment mechanism 3. The syringes output from the feed port 211 fall into the limiting grooves 221 in sequence, realizing orderly single-row conveying and advancing towards the adjustment mechanism 3.

[0047] Preferably, there are two electric push rods 37, and each of the two electric push rods 37 has an adjusting baffle 36 at its output end. The opening of the adjusting baffle 36 gradually decreases along the delivery direction of the syringe, which facilitates the introduction of the syringe with the elastic scraper 32.

[0048] The working principle of this invention is as follows: During delivery, the syringe first enters the feeding mechanism 2. Utilizing the inclined surface of the feeding buffer platform 21 and the arc-shaped feeding port 211, the syringe automatically adjusts its axis and falls into the limiting groove 221 of the first conveying platform 22, forming a single-row orderly delivery. When the syringe is advanced to the adjusting mechanism 3, the air flotation platform 34 sprays compressed air through the ventilation micro-holes 341 on its surface, forming a stable air cushion below the syringe, making the syringe slightly suspended and greatly reducing movement resistance. At this time, the servo motor 33 drives the elastic scraper 32 to rotate, and the elastic scraper 32 gently pushes the suspended syringes, pushing them one by one to the support rod 35. Through the action of the vision sensor 38 and the electric push rods 37 on both sides, the adjusting baffle 36 is extended and retracted, using its gradually narrowing channel to correct the attitude of the syringe, so that it enters the discharge port in a straight and centered posture. The syringe smoothly falls between the two limiting components 41 of the conveying mechanism 4. Under the action of its own weight and inertia, the syringe presses against the two sliders 412, causing the sliders 412 to overcome the elastic force of the springs 411 and slide back and forth along the slide grooves 413, making way for the syringe to accurately fall into the arc-shaped grooves 421. After the syringe is in place, the springs 411 push the sliders 412 on both sides to return to their original positions, clamping the syringe from both ends and completing the stable fixation. Finally, the second conveying table 42 drives the syringe to be smoothly conveyed forward.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
