Example

[0054] See Figures 1-3 As shown, a capping device for syringe filling is mounted on a mounting platform 1, comprising:

[0055] The upper cover mechanism 2 includes a vibratory feeder 21 and a feeding track 22. The vibratory feeder 21 is used to arrange the caps in an orderly manner and transport them to the feeding track 22. The caps can move along the feeding track 22 to the feeding station.

[0056] The pushing mechanism 3 is located on one side of the loading track 22 and is used to push the cap located at the loading station to the clamping station. The pushing mechanism 3 includes a pushing cylinder 31 and a pushing block 32. The extension and retraction movement of the pushing cylinder 31 can drive the pushing block 32 to push the cap to the clamping station.

[0057] A rotary clamping mechanism 4 is provided at the clamping station and is used to clamp the cap located at the clamping station. The rotary clamping mechanism 4 includes a cap clamping cylinder 41, a cap clamping block and a rotary drive assembly. The cap clamping cylinder 41 drives the cap clamping block to clamp or release the cap. The rotary drive assembly is used to drive the cap clamping cylinder to rotate.

[0058] Syringe transfer mechanism 5 is located outside the rotary clamping mechanism 4 and is used to grab the syringe and move it to the clamping station. Syringe transfer mechanism 5 includes a clamping component and a moving drive component. The clamping component is used to grab the syringe, and the moving drive component drives the clamping component to move between the clamping station and the unloading station.

[0059] This invention uses a pusher mechanism 3 to transfer the capping mechanism from the top capping mechanism 2 to the rotary clamping mechanism 4, while the syringe transfer mechanism 5 transfers the syringe to the top of the rotary clamping mechanism 4 for capping installation. The entire device is compact and can achieve automated production by means of the connection and cooperation of various mechanisms, reducing manual operation and improving the efficiency of syringe capping time.

[0060] In this embodiment, the main function of the syringe transfer mechanism 5 is to transfer the syringe from one station to another for capping. In this embodiment, the moving drive component in the syringe transfer mechanism 5 is mounted on the support 51, which is fixed to the mounting platform 1, ensuring the stability and accuracy of the entire structure.

[0061] Specifically, the moving drive assembly includes a horizontal moving cylinder 52 and a horizontal linear slide rail 53, both located on the upper surface of the support base 51. The horizontal linear slide rail 53 is connected to a first support plate 54 via a slider, allowing the first support plate 54 to slide freely in the horizontal direction. The piston end of the horizontal moving cylinder 52 is connected to the first support plate 54 via a connector. When the horizontal moving cylinder 52 operates, it can push or pull the first support plate 54 to move precisely horizontally along the horizontal linear slide rail 53, thereby realizing the transfer of the syringe between different workstations.

[0062] The clamping assembly is mounted on the first support plate 54 and consists of a syringe clamping cylinder 55 and a syringe clamping block 56. The syringe clamping block 56 is designed to grip the shape of the syringe, ensuring stability during the gripping process. The syringe clamping cylinder 55 controls the opening and closing of the syringe clamping block 56 to accurately grip and place the syringe.

[0063] During the operation of the syringe transfer mechanism 5, the telescopic movement of the horizontal moving cylinder 52 drives the first support plate 54 to make precise horizontal displacement along the horizontal linear slide rail 53. This action enables the syringe clamping cylinder 55 and its connected syringe clamping block 56, which are mounted on the first support plate 54, to move smoothly between the clamping station and the unloading station. Specifically, the external robotic arm places the syringe at the clamping station, and then the syringe clamping block 56 grasps it at the clamping station and installs the cap there. After completion, the syringe is transferred to the unloading station by the push of the horizontal moving cylinder 52.

[0064] The support seat 51 at the unloading station is equipped with a downwardly inclined unloading plate 6. This design helps ensure that the syringe can be smoothly released from the clamp after the capping operation and slide down the unloading plate 6 to the collection area. The inclination angle of the unloading plate 6 and its relative arrangement can be adjusted according to actual production needs to ensure that the syringe can slide down smoothly without clogging.

[0065] The rotary drive assembly 4, as the core component of the syringe capping device, is responsible for the precise installation of the caps. This assembly mainly includes a rotary mounting frame 42 and a rotary worktable 45 (also known as a turntable-type rotary platform). The lower base of the rotary worktable 45 is fixed to the rotary mounting frame 42, while its upper turntable is equipped with a capping clamping cylinder 41, which is used to directly control the capping clamping block to clamp or release the caps.

[0066] A rotary motor 43 is installed inside the rotary mounting bracket 42. It is connected to the rotary worktable 45. The operation of the rotary motor 43 drives the upper turntable of the rotary worktable 45 to rotate. By adopting a double-layer structure for the rotary worktable 45, the upper turntable of the rotary worktable 45 is driven to rotate by the rotary motor 43 while keeping the lower base of the rotary worktable 45 stationary. This, in turn, drives the cap clamping cylinder 41 to rotate.

[0067] In addition, a vertical lifting cylinder 44 is provided at the bottom of the rotating mounting frame 42. Its main function is to adjust the vertical height of the entire rotating mounting frame 42 so that the cap is pressed into contact with the syringe.

[0068] To further enhance the stability of the rotating mounting bracket 42 during vertical movement, vertically distributed linear slide rails are provided on the support base 51, and the rotating mounting bracket 42 is mounted on these linear slide rails via sliders. The vertical lifting cylinder 44 is fixed to the mounting platform 1. This ensures smooth vertical movement of the rotating mounting bracket 42.

[0069] In actual operation, when capping is required, the capping clamping cylinder 41 first drives the capping clamping block to firmly clamp the cap. Then, the vertical lifting cylinder 44 is activated, pushing the rotating mounting bracket 42 upward to make the cap in close contact with the tip of the syringe. Next, the rotary motor 43 starts working, driving the upper turntable of the rotary worktable 45 to rotate, which in turn causes the capping clamping cylinder 41 and the cap to rotate together, achieving precise assembly of the cap and syringe.

[0070] Furthermore, in the rotary drive assembly 4, a first sensor is configured on one side of the cap clamping cylinder 41 to detect whether the cap clamping cylinder 41 has correctly clamped the cap. The placement of this sensor ensures higher reliability of the system's automated control, and can promptly issue an alarm or signal when the cap is not correctly clamped, so that adjustments or reoperation can be made.

[0071] The cap clamping cylinder 41 employs a four-jaw cylinder design. This type of cylinder provides a more uniform and stable clamping force, ensuring that the cap does not loosen or shift during the entire rotation installation process. Each jaw is equipped with a cap clamping block, which is customized according to the specific shape of the cap to achieve optimal gripping performance. The four-jaw design not only increases clamping stability but also improves the device's adaptability to caps of different sizes.

[0072] The feeding mechanism 3, as a key component in the syringe capping device responsible for pushing the caps from the loading station to the clamping station, is crucial for the efficient operation of the entire system due to the precision and stability of its design. Specifically, the feeding block 32 is one of the core components of this mechanism, and it is equipped with a slot. The direction of this slot is consistent with the driving direction of the feeding cylinder 31, ensuring linear motion when pushing the object. A top plate 33 is slidably disposed inside the slot, which can slide along a predetermined direction within the slot, thereby pushing the caps.

[0073] The pusher block 32 is equipped with a feeding chute corresponding to the feeding station. This feeding chute is directly connected to the slot, ensuring that the cap can move smoothly from the feeding track into the slot. This design guarantees the smooth transport of the cap.

[0074] The piston end of the pusher cylinder 31 is connected to a first push plate, which has guide sleeves at both ends. A guide rod 34 is installed inside the guide sleeve; one end of the guide rod 34 is fixed to the pusher block 32, while the other end passes through the guide sleeve. To enhance system stability and reduce vibration, a spring 35 is fitted onto the guide rod 34. One end of the spring 35 abuts against the pusher block 32, and the other end abuts against the first push plate. This design effectively buffers the movement of the pusher cylinder 31, making the pushing process smoother. One end of the top plate 33 is fixed to the first push plate.

[0075] When the pusher cylinder 31 operates, the extension and retraction of its piston causes the first pusher plate to move back and forth. Since one end of the top plate 33 is fixed to the first pusher plate, it is in rigid contact, while the spring and the first pusher plate are in elastic contact. Therefore, when the first pusher plate moves forward under the drive of the pusher cylinder 31, the front end of the top plate 33 will protrude forward relative to the pusher block 32, thereby pushing the cap on the pusher block 32 into the clamping area surrounded by the cap clamping block, and fixing the cap by the cap clamping cylinder 41.

[0076] Furthermore, the pusher cylinder 31 is mounted on the pusher support plate 36, which is fixed to the support seat 51, ensuring the stability and precision of the entire pusher mechanism 3. To further improve the accuracy and stability of the pusher block 32's movement, a first linear slide rail aligned with the driving direction of the pusher cylinder 31 is provided on the pusher support plate 36. The pusher block 32 is connected to the first linear slide rail via a slider, allowing it to move smoothly back and forth along the linear slide rail under the drive of the pusher cylinder 31.

[0077] The syringe filling capping device provided by this utility model is a component of a complete syringe glue filling equipment. It shares the control unit, power supply unit, and air supply unit of the whole machine to realize the automated operation of the capping device.

[0078] This invention, through the connection of the pushing mechanism 3, allows the caps to be smoothly transferred from the upper cover mechanism 2 to the rotary clamping mechanism 4. Specifically, the vibratory feeder 21 first arranges the caps in an orderly manner and transports them to the designated loading station via the loading track 22. Then, the pushing cylinder 31 drives the pushing block 32 to move precisely along the first linear slide rail, pushing the caps located at the loading station to the clamping station of the rotary clamping mechanism 4. This design ensures that the caps maintain the correct posture and position during the transfer process, avoiding possible jamming or misalignment problems.

[0079] Meanwhile, the syringe transfer mechanism 5 is responsible for gripping the syringe and accurately moving it above the rotary clamping mechanism 4 to await the capping installation operation. The syringe transfer mechanism 5 includes a clamping assembly and a moving drive assembly. The clamping assembly is used to firmly grip the syringe, while the moving drive assembly ensures that the syringe can move efficiently and accurately between the clamping station and the unloading station. After the syringe is moved to the clamping station, the capping clamping cylinder 41 in the rotary clamping mechanism 4 drives the capping clamping block to clamp the cap. Then, driven by the vertical lifting cylinder 44, it moves upward, pressing the cap into contact with the syringe. Then, the rotary motor 43 is started, which drives the entire rotary worktable 45 to rotate, thereby achieving precise docking and installation of the cap and syringe.

[0080] The entire device achieves a compact and highly automated production process through close collaboration between its various mechanisms. This design not only reduces the need for manual intervention and improves the continuity and stability of production, but also significantly enhances the time efficiency of syringe capping.
