[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A syringe dispensing device, comprising:

[0007] The indexing plate assembly includes an indexing plate, on which several outwardly movable carrier assemblies are evenly distributed circumferentially. Each carrier assembly is equipped with a syringe fixture for fixing a syringe. The syringe fixture has a compression chamber, which contains a syringe carrier plate and a spring. The upper end of the spring abuts against the syringe carrier plate, and the lower end abuts against the bottom of the compression chamber, providing a restoring force when the syringe is compressed.

[0010] The measuring component includes a measuring cylinder, which is equipped with a cylinder position sensor for monitoring the position of the piston of the measuring cylinder; the piston end of the measuring cylinder is equipped with a seal, which, under the drive of the measuring cylinder, can be pressed into the bottom of the syringe below it to expel the air inside the syringe.

[0011] The material pressing assembly includes a material pressing cylinder, and a pressure plate is provided at the piston end of the material pressing cylinder. The pressure plate corresponds to the position of the measuring cylinder. When the material pressing cylinder drives the pressure plate to press down, the syringe directly below the measuring cylinder moves down, and the syringe carrier plate compresses the spring, so that the bottom outlet of the syringe is tightly connected to the dispensing needle for dispensing operation. When the material pressing cylinder retracts, the pressure plate moves up, and under the restoring force of the spring, the bottom outlet of the syringe separates from the dispensing needle.

[0012] As a further improvement of one embodiment of the present utility model, the carrier assembly includes a first carrier plate, a linear slide rail and a push cylinder. The linear slide rail and the push cylinder are disposed on an indexing plate. The first carrier plate is slidably disposed on the linear slide rail by a slider. The push cylinder is connected to the first carrier plate by a connector. A syringe fixture is disposed on the first carrier plate.

[0013] As a further improvement of one embodiment of the present invention, four syringe fixtures are arranged in a matrix on the first carrier plate.

[0014] As a further improvement of one embodiment of the present invention, the base is provided with a slot for embedding pipelines.

[0015] As a further improvement of one embodiment of the present utility model, the pipeline includes a flexible tube and a rigid tube. One end of the rigid tube is connected to a glue storage tank, and the other end of the rigid tube is connected to a tee connector. A switch valve and a flow valve are provided on the rigid tube.

[0016] As a further improvement of one embodiment of the present invention, the base is provided with a T-shaped locking block and a squeezing cylinder, and the squeezing cylinder cooperates with the T-shaped locking block to block the hose on one side of the T-shaped locking block.

[0017] As a further improvement of one embodiment of the present invention, the extrusion mechanism includes a pressure plate that is matched with the glue storage tank, a sealing ring is provided on the pressure plate, the pressure plate is fixedly connected to the output end of the electric cylinder, and the electric cylinder is mounted on the gantry frame.

[0018] As a further improvement of one embodiment of the present invention, the number of carrier components is four, and the indexing plate can move the corresponding syringe fixture to directly above the glue-dispensing needle by rotating 90° each time.

[0019] The above technical solution has the following beneficial effects: by using the indexing plate and syringe fixture, in conjunction with the measuring component and the pressing component, the syringe can be quickly vented, filled, and separated, thereby improving the syringe dispensing efficiency.

Example

[0054] See Figures 1-3 As shown, a syringe dispensing device comprises an indexing plate assembly 1, a dispensing connection assembly 2, a dispensing and extrusion assembly 3, a measuring assembly 4, and a pressing assembly 5, wherein:

[0055] The indexing plate assembly 1 includes an indexing plate 11, on which several outwardly movable carrier assemblies 12 are evenly distributed circumferentially. Each carrier assembly 12 is equipped with a specially designed syringe fixture 13 for fixing the syringe. The syringe fixture 13 has a compression chamber, within which a syringe carrier plate and a spring are located. The upper end of the spring abuts against the syringe carrier plate, and the lower end abuts against the bottom of the compression chamber, providing a restoring force when the syringe is compressed. Furthermore, the design of the syringe fixture 13 allows it to be adjusted as needed to accommodate syringes of different sizes, improving the versatility and flexibility of the device.

[0056] The dispensing connection assembly 2 is located on one side of the indexing plate 11 and includes a base 21. A dispensing needle 22 is mounted on the top of the base 21. The dispensing needle 22 is connected to the glue storage tank 31 through a pipeline, ensuring smooth flow of the glue. To improve dispensing efficiency and accuracy, a valve system with flow control function can be considered to more precisely control the amount of glue dispensed each time.

[0057] The glue storage and extrusion assembly 3 includes a glue storage tank 31 disposed outside the indexing plate 11 and an extrusion mechanism 32. The extrusion mechanism 32 is disposed above the glue storage tank 31 and is used to extrude the glue material in the glue storage tank 31 into the dispensing needle 22. The syringe fixture 13 on the indexing plate 11 can rotate and move to be directly above the dispensing needle 22 to prepare for syringe dispensing.

[0058] The measuring assembly 4 includes a measuring cylinder 41 mounted on a bracket 6. A cylinder position sensor 42 is mounted on the measuring cylinder 41 to monitor the position of the piston. A seal is located at the piston end of the measuring cylinder 41. Driven by the measuring cylinder 41, the seal is pressed into the bottom of the syringe below, expelling air from the syringe.

[0059] The pressing assembly 5 includes a pressing cylinder 51 mounted on a bracket 6. A pressure plate 52 is provided at the piston end of the pressing cylinder 51, and the pressure plate 52 corresponds to the position of the measuring cylinder 41. When the pressing cylinder 51 drives the pressure plate 52 downwards, the syringe directly below the measuring cylinder moves downwards, compressing the spring on the syringe carrier plate, thus tightly connecting the bottom outlet of the syringe with the dispensing needle for dispensing operations. When the pressing cylinder 51 retracts, the pressure plate moves upwards, and under the restoring force of the spring, the bottom outlet of the syringe separates from the dispensing needle.

[0060] This invention achieves rapid venting, precise filling, and convenient separation during the syringe dispensing process through the synergistic effect of its components, greatly improving production efficiency. Specifically, the measuring component 4 and the pressing component 5 are fixed in the middle position of the indexing plate 11 by a bracket 6.

[0061] Specifically, the extrusion mechanism 32 includes a pressure plate 321 that matches the rubber storage tank 31. The pressure plate 321 is equipped with a sealing ring to ensure no leakage occurs during extrusion. The pressure plate 321 is fixedly connected to the output end of an electric cylinder 322, which is mounted on a gantry frame 323. This design not only ensures uniform pressure applied to the rubber compound but also makes the entire operation more automated and precise.

[0062] The piping connecting the glue storage tank 31 and the dispensing needle 22 consists of a flexible tube and a rigid tube. One end of the rigid tube is directly connected to the glue storage tank 31, and the other end is connected to the flexible tube via a tee connector 33. The rigid tube is equipped with a switch valve 34 and a flow valve 35, a design that allows users to adjust the flow rate and opening / closing status of the glue as needed, thus achieving more precise control. The flexible tube is connected at both ends to the tee connector 33 and the dispensing needle 22, ensuring system flexibility and facilitating maintenance. Furthermore, a retaining groove 23 for inserting the flexible tube is provided on the base 21, which helps maintain the neatness and order of the piping and prevents damage or leakage caused by external factors.

[0063] In this embodiment, the number of dispensing needles 22 is set to two, which means that dispensing operations can be performed on two syringes simultaneously, significantly improving work efficiency. To further enhance the controllability of the system, a T-shaped locking block 24 and a squeezing cylinder 25 are also provided on the base 21. The squeezing cylinder 25 can be used in conjunction with the T-shaped locking block 24, and when needed, the dispensing operation on a specific path can be controlled by blocking the tubing on one side of the T-shaped locking block.

[0064] The carrier assembly 12 is designed to ensure that the syringe can be moved accurately and efficiently to the designated position for dispensing. Specifically, the carrier assembly 12 includes a first carrier plate 121, a linear slide rail 122, and a push cylinder. Both the linear slide rail 122 and the push cylinder are mounted on the indexing plate 11, while the first carrier plate 121 is connected to the linear slide rail 122 via a slider, allowing the first carrier plate 121 to move smoothly along the linear slide rail 122 under the drive of the push cylinder. The push cylinder is connected to the first carrier plate 121 via a connector. This design not only ensures efficient force transmission but also allows for the addition of guide posts and guide sleeves when necessary, improving the stability and reliability of the system.

[0065] In this embodiment, four syringe fixtures 13 are arranged in a matrix on the first carrier plate 121. This layout allows for the simultaneous processing of multiple syringes, improving work efficiency. Each syringe fixture 13 has an independent compression chamber and spring structure to adapt to different pressure requirements and ensure the safety and stability of the syringe under pressure.

[0066] In actual operation, the syringe fixture 13 on the first carrier plate 121 can move on the linear slide rail 122 through the action of the push cylinder, so that the two sets of syringe fixtures are respectively located directly below the dispensing needle 22, thereby completing the dispensing operation. This design not only simplifies the operation process of the equipment, but also reduces the need for manual intervention, further improving production efficiency and product quality consistency.

[0067] In this embodiment, four carrier assemblies 12 are evenly distributed around the indexing plate 11. Each time the indexing plate 11 rotates 90°, one carrier assembly 12 can be precisely moved to the position directly below the dispensing needle 22 to perform the dispensing operation. This design not only ensures the accuracy of the operation but also makes the entire process efficient and orderly. The syringe fixture 13 on each carrier assembly 12 can operate independently, thereby supporting the ability to operate multiple stations simultaneously and further improving production efficiency.

[0068] The syringe dispensing device provided by this utility model is a component of a complete syringe dispensing equipment. It shares the control unit, power supply unit, air supply unit, etc. of the whole machine to realize the automated operation of the syringe dispensing device.

[0069] This invention, through the application of the indexing plate 11 and the syringe fixture 13, combined with the collaborative work of the measuring component 4 and the pressing component 5, achieves rapid and accurate venting, filling and separation operations for the syringe, greatly improving the overall efficiency of syringe glue filling.

[0070] First, the indexing plate 11 is designed to allow the carrier assembly 12 to be precisely positioned within a set angle (e.g., 90° rotation at a time). The syringe fixture 13 on each carrier assembly 12 can hold the syringe and ensure its accurate positioning. This design not only enables the equipment to switch efficiently between different workstations but also provides reliable positional assurance for subsequent processes.

[0071] Next, when the carrier assembly 12 moves to a specific position, the measuring assembly 4 begins to operate. The measuring cylinder 41, under the monitoring of the cylinder position sensor 42, expels air from the syringe through a seal at the end of its piston. The selection of a corrosion-resistant and highly elastic material for the seal ensures long-term stable performance.

[0072] Subsequently, the pressure assembly 5 comes into play. The pressure cylinder 51 drives the pressure plate 52 to press down, making the bottom outlet of the syringe tightly connected to the dispensing needle 22, ready for dispensing. The spring design inside the syringe fixture 13 ensures that the syringe can quickly return to its original shape after the pressure is released, thus easily disengaging from the dispensing needle.

[0073] Finally, the electric cylinder 322 in the rubber storage and extrusion assembly 3 drives the pressure plate 321 to apply uniform pressure to the rubber material in the rubber storage tank 31, and the flow rate of the rubber material is precisely controlled by the flow valve 35 to complete the filling process. The design of rigid pipes and flexible pipes in the piping system ensures both system flexibility and ease of maintenance.

[0074] In summary, through the precise coordination between the above components, this invention provides an efficient and reliable syringe dispensing solution that is suitable for a variety of application scenarios and has good versatility and scalability.
