Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a high-precision syringe assembly device. Background Technology

[0002] As a critical consumable in the medical field, the assembly quality of syringes directly affects their safety and reliability. In traditional syringe manufacturing, the installation of the spinlock (a key component used to connect with other tubing) mainly relies on manual or semi-automatic equipment. Operators must manually pre-position the spinlock to the syringe port and then rotate it to make it rotatable. Manual operation is prone to incomplete locking due to deviations in force or angle, leading to the risk of leakage or detachment. Some devices require manual rotation and adjustment after installation to give the spinlock rotational freedom, which is inefficient. There is an urgent need for a convenient and efficient device for installation. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a high-precision syringe assembly device that completes the installation of the spin lock in one go without manual adjustment. It is suitable for the installation of various syringe models and ensures processing efficiency.

[0004] Specifically, this utility model discloses a high-precision syringe assembly device for installing a spin lock on the syringe head, comprising:

[0005] The frame, equipped with a base plate, is used to mount:

[0009] A positioning component for positioning the syringe.

[0010] The advantages of adopting the above technical solution are that it enables automated installation, eliminates the need for manual adjustment, has high assembly efficiency, a compact structure, and strong reliability.

[0011] Furthermore, the frame is equipped with a support rod, and a top plate is installed on the top of the support rod. The downward driving component is installed on the top plate, and a lifting frame is provided on the lower side of the support rod. The downward driving component drives the lifting frame to move, and the lifting frame moves up and down along the support rod.

[0012] The advantage of adopting the above technical solution is that by using the downward driving component to drive the lifting frame to rise and fall, the entire pressing process moves smoothly and ensures that the pressing is in place.

[0013] Furthermore, the rotary drive assembly is disposed within the lifting frame, and the rotary drive component is a servo motor, the output end of which is connected to the pressing head to drive the pressing head to rotate.

[0014] The advantage of adopting the above technical solution is that by setting a servo motor directly connected to the pressing head, the pressing head can be driven to rotate. The number of rotations of the servo motor can be controlled. Compared with the synchronous belt drive, the drive is more direct, ensuring rotational accuracy and service life.

[0015] Furthermore, a fixing hole is provided in the middle of the pressing head, a strip-shaped protrusion is provided on the outer side of the self-rotating lock, and a strip-shaped groove is provided in the fixing hole to cooperate with the strip-shaped protrusion.

[0016] The advantage of adopting the above technical solution is that when the pressing head presses down, the strip groove plays a positioning role. At the same time, after the pressing is completed, the pressing head rotates, and the strip groove will drive the strip protrusion to rotate, completing the loosening action after pressing.

[0017] Furthermore, the positioning component includes a bottom positioning plate disposed on the base plate, the bottom positioning plate being provided with positioning posts for connecting and fixing to the base plate.

[0018] The advantage of adopting the above technical solution is that the bottom positioning plate is used to position the product, ensuring the product's position is accurate and the pressing position is accurate.

[0020] The advantages of adopting the above technical solution are that it enables quick replacement of the pressing head, and during the rotation process, the protrusion on the pressing head cooperates with the connecting groove in the adapter block to prevent the pressing head from slipping. The magnetic setting makes it easy to replace, and different sizes of pressing heads can be replaced to adapt to the pressing of different models of products.

[0021] Furthermore, the bottom positioning plate includes a receiving part and a positioning groove. The receiving part is used to receive the syringe, and a positioning step is provided on the side of the receiving part. The positioning groove is provided at the positioning step.

[0022] The advantage of adopting the above technical solution is that the receiving part is used to support the entire syringe, and a positioning groove is set for positioning. The positioning groove on the side also plays a positioning role. During the installation process, the syringe is kept in a vertical position, ensuring that the installation position is accurate and will not damage the syringe.

[0023] Furthermore, the clamping assembly includes a clamping cylinder, the clamping cylinder is provided with a gripper, and a buffer layer is provided on the inner side of the gripper.

[0024] The advantages of adopting the above technical solution are that the grippers are used to clamp the product and prevent it from shaking, while the buffer layer effectively prevents scratches on the product surface and ensures the product's aesthetic appearance.

[0025] Furthermore, the bottom positioning plate is provided with multiple sets, each set having a different positioning groove size.

[0026] The advantage of adopting the above technical solution is that when pressing different models of products, only different bottom positioning plates need to be replaced, which improves the applicability of the entire equipment and allows for the installation of different models of syringes.

Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings.

[0040] like Figure 1-3 As shown, this utility model discloses a high-precision syringe assembly device for installing a spin lock 8 on the syringe head, comprising:

[0041] The frame 1 is equipped with a base plate 11, on which the following are mounted:

[0042] The press-fit assembly includes a press-fit head 2 and a pressing drive 21. The pressing drive 21 drives the press-fit head 2 to move up and down to install the spin lock 8 onto the syringe head. The press-fit head 2 is provided with an adsorption hole 22 for adsorbing the spin lock 8.

[0043] The rotating assembly includes a rotating drive 3, which drives the pressing head 2 to rotate, and the pressing head 2 drives the spin lock 8 to rotate.

[0044] Clamping assembly 4 is used to clamp and fix the syringe;

[0045] A positioning component for positioning the syringe.

[0046] The advantage of adopting the above technical solution is that the press-fitting component presses the spin lock 8 against the end of the syringe, and then the rotating component drives the spin lock 8 to rotate, so that the spin lock 8 can rotate without subsequent adjustment, resulting in high assembly efficiency.

[0047] The machine frame 1 is equipped with support rods 6, and a top plate 61 is mounted on the top of the support rods 6. A pressing drive component 21 is mounted on the top plate 61. A lifting frame 7 is provided on the lower side of the support rods 6. The pressing drive component 21 drives the lifting frame 7 to move. There are four support rods 6. The pressing drive component 21 can be a cylinder, the main body of which is fixed on the top plate 61, and the extended end is fixedly connected to the top of the lifting frame 7. The lifting frame 7 is also equipped with a bushing to move it up and down along the support rods 6. The support rods 6 are smooth guide rods to ensure accurate pressing position. The pressing drive component 21 drives the lifting frame 7 to move up and down, making the entire pressing process smooth and ensuring that the pressing is in place.

[0048] Furthermore, a rotary drive component is installed inside the lifting frame 7. The rotary drive component 3 is a servo motor, and its output end is connected to the pressing head 2 to drive the pressing head 2 to rotate. The lifting frame 7 is provided with a lifting base plate. The main body of the servo motor is mounted on the lifting base plate, and its output end passes through the lifting base plate and is connected to a transition block 31 via a coupling. The pressing head 2 is provided with a connecting part 24, such as... Figure 4-6 The connecting part 24 has a protrusion 25 at its top, and the adapter block 31 has a connecting groove into which the connecting part 24 extends, located at the bottom of the adapter block 31. A magnet is fixed in the connecting groove. The connecting part 24 of the pressing head 2 is a magnetically attractive metal part that is magnetically fixed to the adapter block 31. This allows for quick replacement of the pressing head 2. During rotation, the protrusion 25 on the pressing head 2 engages with the groove in the adapter block 31 to prevent the pressing head 2 from slipping. The magnetic design facilitates replacement, allowing for the use of different sized pressing heads 2 to accommodate the pressing of different product models.

[0049] Furthermore, a fixing hole 23 is provided in the middle of the press head 2, and a strip-shaped protrusion 81 is provided on the outer side of the self-rotating lock 8, such as... Figure 7-8 As shown, a strip groove 231 that mates with the strip protrusion 81 is provided inside the fixing hole 23. After pressing down, the pressing head 2 rotates, and the strip groove 231 drives the strip protrusion 81 to rotate, completing the loosening action after pressing down. At the same time, the adsorption hole 22 passes through the pressing head 2 and communicates with the fixing hole 23. The pressing head 2 is connected to a vacuum generator. Before pressing down, the spin lock 8 is first placed in the fixing hole 23 for adsorption and fixation, and then pressed down together with the pressing head 2 to ensure that the pressing is in place.

[0050] In some implementations, the positioning assembly includes a bottom positioning plate 5 disposed on the base plate 11. A positioning post is fixedly disposed on the lower side of the bottom positioning plate 5 for connecting and fixing to the base plate 11. The base plate 11 is provided with positioning holes, which cooperate with the positioning post to fix the bottom positioning plate 5, making it convenient to replace the bottom positioning plate 5. At the same time, the bottom positioning plate 5 can also be fixed by screw fastening.

[0051] At the same time, such as Figure 9As shown, the bottom positioning plate 5 includes a receiving part 51 and a positioning groove 52. The receiving part 51 is used to receive the syringe, and a positioning step 53 is provided on the side of the receiving part 51. The positioning groove 52 is located at the positioning step 53. The bottom positioning plate 5 has multiple sets, and the positioning groove 52 of each set has a different size. When pressing different models of products, only different bottom positioning plates 5 need to be replaced, which improves the applicability of the entire device and allows for the installation of different models of syringes.

[0052] A vertical plate is also installed on the base plate 11. A central positioning plate 54 is fixedly installed on the vertical plate for central positioning. The two positioning plates can accurately position the syringe and ensure that the syringe is always in a vertical position during installation, ensuring accurate installation and preventing damage to the syringe.

[0053] In some implementations, the clamping assembly 4 includes a clamping cylinder 41 with grippers 42 and a buffer layer on the inner side of the grippers 42. The grippers 42 are used to clamp the product and prevent it from shaking, while the buffer layer effectively prevents scratches on the product surface and ensures the product's aesthetic appearance. The clamping cylinder 41 is horizontally mounted on the base plate, and a horizontal cylinder 9 is connected to its rear side. Pulling the clamping cylinder 41 horizontally moves it, allowing it to move closer to the product when needed, and then retract after clamping, facilitating syringe loading.

[0054] In the processing, firstly, a person or a robot places the syringe on the bottom positioning plate 5 and positions it using the positioning step 53. Then, the spin lock 8 is placed in the fixing hole 23 inside the pressing head 2, and the internal suction hole 22 holds the spin lock 8 in place. Then, the switch button is activated, and the pressing drive 21 drives the pressing head 2 to descend. After the pressing head 2 descends to its position, the rotation drive 3 drives the pressing head 2 to rotate, allowing the spin lock 8 to rotate with the syringe. When connecting other pipes, the spin lock 8 can rotate with the pipe to prevent the pipe from falling off. After assembly, no manual readjustment is required, and the installation is completed in one go, reducing assembly steps and improving assembly efficiency and quality.

[0055] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
