Syringe assembly device

Abstract

The present invention provides a syringe assembly device, including a material dividing mechanism, a transplanting mechanism and a constant pressure mechanism. In this scheme, the push rod is received by the material dividing mechanism, the position of the push rod is moved by the transplanting mechanism and the push rod is inserted into the syringe. Since the opening at the lower end of the syringe is blocked and a rubber plug is placed at the upper end opening of the syringe, during the process of inserting the push rod into the syringe, the lower end of the push rod is stuck in the rubber plug and compresses the air in the syringe. After the transplanting mechanism is separated from the push rod, the pressure on the push rod disappears, and the compressed air rebounds and pushes the push rod upward for a distance, thereby achieving a fixed height of the push rod outside the syringe after the syringe is assembled, facilitating operations such as grabbing the push rod in subsequent processes, and improving the product output and qualified rate.

Description

Technical Field

[0001] The present invention relates to the technical field of medical industrial equipment, in particular to a syringe assembly device. Background Art

[0002] Syringes are primarily categorized as needle-based and needle-free syringes. Each syringe consists of a syringe barrel, a push rod, and a rubber stopper, all of which must be assembled together during production. After the push rod is inserted into the barrel, it must be grasped and removed. However, the height at which the push rod protrudes from the barrel after insertion is not fixed, affecting the success rate of grasping and other operations. Alternatively, additional steps are required to adjust the push rod's height to ensure the success rate of subsequent operations. Consequently, in existing syringe assembly, the push rod's assembly position is uncertain, impacting production efficiency and product qualification rates. Summary of the Invention

The sealing assembly also includes a horizontal plate installed on the sealing cylinder, and a plurality of push rods are arranged side by side on the horizontal plate, and the plurality of push rods and the plurality of limiting holes are arranged in a one-to-one correspondence.

[0007] Furthermore, the pressing assembly is located above the carrier, and the pressing assembly includes a pressing cylinder and a pressing plate. The pressing cylinder drives the pressing plate to rise and fall, and the pressing plate has an avoidance hole. The pressing plate is used to press the upper end of the injection cylinder, and the avoidance hole avoids the opening of the upper end of the injection cylinder.

[0008] Furthermore, the constant pressure mechanism also includes a correction component, which is installed on the pressing component to rise and fall with the pressing component. The correction component has a correction hole, which corrects the position of the push rod so that the push rod is aligned with the upper end opening of the injection barrel.

[0009] Furthermore, the correction assembly includes a correction cylinder and two correction plates. The correction cylinder is installed on the downward pressure assembly. The correction cylinder drives the two correction plates to move closer to or away from each other. The correction plates have correction grooves. When the two correction plates are close to each other, the relative correction grooves of the two correction plates form correction holes. When the two correction plates are away from each other, the two correction plates avoid the push rod.

[0010] Furthermore, the correction hole includes a guide section and a correction section that are interconnected, the guide section is a tapered section, the correction section is a straight section, and the end of the tapered section with a larger diameter faces the transplanting mechanism.

[0011] Furthermore, the material dividing mechanism includes a material dividing assembly, a lifting assembly and a guide assembly. The guide assembly has N guide channels for guiding the push rods respectively. The N guide channels are arranged side by side along the set direction. The material dividing assembly has 2N receiving grooves arranged side by side along the set direction. The material dividing assembly is arranged to be movable back and forth along the set direction so that each receiving groove can correspond to a guide channel and receive the push rod output from the guide channel.

[0012] Furthermore, the material dividing mechanism also includes a first cylinder and a second cylinder, the first cylinder drives the material dividing assembly to move closer to or away from the jacking assembly, and the second cylinder drives the first cylinder and the material dividing assembly to move along the set direction; the jacking assembly includes a jacking cylinder and 2N groups of jacking clamps, the jacking cylinder drives the 2N groups of jacking clamps to rise and fall, and each group of clamps clamps a push rod respectively.

The limiting cylinder is fixed to the driving cylinder and is located between the two pneumatic jaws. The two pneumatic jaws are used to clamp the push rod, and the limiting cylinder is used to limit the top end of the push rod.

[0015] In this solution, the push rod is received by the material distribution mechanism, the position of the push rod is moved by the transplanting mechanism and the push rod is inserted into the syringe. Since the opening at the lower end of the syringe is blocked and a rubber plug is placed at the upper end opening of the syringe, during the process of inserting the push rod into the syringe, the lower end of the push rod is stuck in the rubber plug and compresses the air in the syringe. After the transplanting mechanism is separated from the push rod, the pressure on the push rod disappears, and the compressed air rebounds and pushes the push rod upward for a distance, thereby achieving a fixed height of the push rod outside the syringe after the syringe is assembled. In this way, the assembly position of the push rod is determined, which is convenient for subsequent processes to perform operations such as grabbing the push rod.

[0016] The present invention can effectively control the direction and height of the push rod, so that the push rod has a determined assembly position, which provides convenience for the next process. The constant pressure assembly method is convenient and fast, saves processes, saves development costs, and improves product output and qualification rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts are within the scope of protection of the present invention.

[0042] like Figures 1 to 8As shown, an embodiment of the present invention provides a syringe assembly device, including: a feeding mechanism 100 for receiving a push rod 10; a transplanting mechanism 200 for moving the push rod 10 received by the feeding mechanism 100; a constant pressure mechanism 300, including a carrier 310, a blocking assembly 320 and a pressing assembly 330, the carrier 310 is used to carry the syringe 20, the blocking assembly 320 is used to abut the opening at the lower end of the syringe 20, and the pressing assembly 330 is used to press the upper end of the syringe 20 so that the blocking assembly 320 seals the opening at the lower end of the syringe 20; wherein, a plug 30 is placed in the upper end opening of the syringe 20, and when the lower end opening of the syringe 20 is sealed, the transplanting mechanism 200 inserts the push rod 10 into the syringe 20, and the lower end of the push rod 10 is stuck in the plug 30, and the push rod 10, the syringe 20 and the plug 30 are assembled to form a syringe.

[0043] In this scheme, the push rod 10 is received by the dividing mechanism 100, and the position of the push rod 10 is moved by the transplanting mechanism 200 and the push rod 10 is inserted into the syringe 20. Since the opening at the lower end of the syringe 20 is blocked and the upper end opening of the syringe 20 is placed with a plug 30, during the process of inserting the push rod 10 into the syringe 20 through the upper and lower transplanting components 210, the lower end protrusion of the push rod 10 is stuck in the groove of the plug 30, and the air in the syringe 20 is compressed by the plug 30. After the transplanting mechanism 200 is separated from the push rod 10, the pressure on the push rod 10 disappears, and the compressed air in the syringe 20 rebounds and pushes the push rod 10 upward for a distance, thereby achieving that after the syringe is assembled, a longer section of the push rod 10 is located outside the syringe 20, and the height outside the syringe 20 is fixed, which facilitates subsequent operations such as grabbing the push rod 10.

[0044] like Figure 3 As shown, the blocking assembly 320 is located below the carrier 310 and includes a blocking cylinder 321 and a push rod 322. The blocking cylinder 321 pushes the push rod 322 up and down, and the push rod 322 is used to abut the opening at the lower end of the syringe 20. In this way, the blocking cylinder 321 pushes the push rod 322 up and down, so that the push rod 322 abuts the opening at the lower end of the syringe 20 to block it.

[0045] Specifically, the upper end of the top rod 322 is made of elastic material, which can improve the sealing reliability and prevent air leakage. Figure 4 As shown, the carrier 310 is provided with a plurality of parallel limiting holes 311, each of which houses a syringe 20. The blocking assembly 320 further includes a horizontal plate 323 mounted on the blocking cylinder 321. A plurality of ejector pins 322 are arranged side by side on the horizontal plate 323, with the ejector pins 322 corresponding to the plurality of limiting holes 311. This allows for simultaneous assembly of multiple syringes, improving production efficiency.

[0046] Among them, the pressing assembly 330 is located above the carrier 310, and the pressing assembly 330 includes a pressing cylinder 331 and a pressing plate 332. The pressing cylinder 331 drives the pressing plate 332 to rise and fall. The pressing plate 332 has an avoidance hole 333. The pressing plate 332 is used to press the upper end of the injection cylinder 20, and the avoidance hole 333 avoids the opening at the upper end of the injection cylinder 20.

[0047] The upper end of the syringe 20 is pressed by the pressing plate 332, so that the syringe 20 and the ejector rod 322 are pressed against each other, thereby ensuring a reliable seal of the lower end opening of the syringe 20. The avoidance hole 333 is provided so that the operation of inserting the push rod 10 into the syringe 20 is not affected.

[0048] Furthermore, the constant pressure mechanism 300 also includes a correction component 340, which is installed on the pressing component 330 to rise and fall with the pressing component 330. The correction component 340 has a correction hole 341, and the correction hole 341 corrects the position of the push rod 10 so that the push rod 10 is aligned with the upper end opening of the injection barrel 20.

[0049] Because the push rod 10 is long and prone to shaking and deflecting, if the lower end of the push rod 10 does not align with the upper opening of the syringe 20, assembly will fail, affecting production efficiency. In this solution, the correction assembly 340 can limit the radial direction of the push rod 10, thereby limiting the position of the push rod 10, preventing deflection, and ensuring that the push rod 10 can accurately enter the syringe 20 when pressed down.

[0050] Specifically, if Figure 5 As shown, the correction assembly 340 includes a correction cylinder 342 and two correction plates 343. The correction cylinder 342 is installed on the pressing assembly 330. The correction cylinder 342 drives the two correction plates 343 to move closer to or away from each other. The correction plates 343 have correction grooves 344. When the two correction plates 343 are close to each other, the correction grooves 344 relative to each other of the two correction plates 343 form a correction hole 341. When the two correction plates 343 are away from each other, the two correction plates 343 avoid the push rod 10.

[0051] With the above arrangement, after the syringe is assembled, the two correction plates 343 can be separated from the push rod 10 to avoid interference when the push rod 10 is moved in subsequent steps.

[0052] The correction hole 341 includes a guide section and a correction section that are interconnected. The guide section is a tapered section, and the correction section is a straight section. The end of the tapered section with a larger diameter faces the transplanting mechanism 200. The push rod 10 can be guided by the tapered section to facilitate the push rod 10 passing through the correction hole 341.

[0053] like Figure 6As shown, the material distribution mechanism 100 includes a material distribution assembly 110, a lifting assembly 120, and a guide assembly 130. The guide assembly 130 has N guide channels for guiding the push rods 10 respectively. The N guide channels are arranged side by side along a set direction. The material distribution assembly 110 has 2N receiving grooves arranged side by side along the set direction. The material distribution assembly 110 is arranged to be movable back and forth along the set direction so that each receiving groove can correspond to a guide channel and receive the push rod 10 output from the guide channel. The lifting assembly 120 is used to clamp and lift the push rod 10 received by the material distribution assembly 110. The multiple guide channels guide the push rods 10. In the material distribution assembly 110, the N receiving grooves first dock with the N guide channels, each receiving groove receiving a push rod 10. Then, the material distribution assembly 110 moves a distance along the set direction to achieve the docking of the other N receiving grooves with the N guide channels, each receiving groove receiving a push rod 10, so that the material distribution assembly 110 receives 2N push rods 10.

[0054] In this solution, the material dividing mechanism 100 also includes a first cylinder 141 and a second cylinder 142. The first cylinder 141 drives the material dividing assembly 110 to move closer to or away from the jacking assembly 120, and the second cylinder 142 drives the first cylinder 141 and the material dividing assembly 110 to move along the set direction; the jacking assembly 120 includes a jacking cylinder 121 and 2N groups of jacking clamps 122. The jacking cylinder 121 drives the 2N groups of jacking clamps 122 to rise and fall, and each group of clamps clamps a push rod 10 respectively.

[0055] Among them, the second cylinder 142 can switch the material distribution mechanism 100 to different positions to correspond to the guide channel, so that each receiving groove can receive the push rod 10. When the material distribution mechanism 100 needs to receive the push rod 10, the first cylinder 141 drives the material distribution mechanism 100 to approach the lifting assembly 120. After the lifting assembly 120 clamps the push rod 10, the first cylinder 141 drives the material distribution mechanism 100 away from the lifting assembly 120, thereby avoiding interference when the lifting assembly 120 lifts the push rod 10.

[0056] like Figure 7 and Figure 8 As shown, the transfer mechanism 200 includes an upper and lower transfer assembly 210 and a lateral transfer assembly 220. The upper and lower transfer assembly 210 includes a lifting cylinder 211 and multiple clamps 212. The lifting cylinder 211 drives the multiple clamps 212 to move up and down, and each clamp 212 clamps a push rod 10. The lateral transfer assembly 220 includes a transverse cylinder 221 and a transverse seat 222. The transverse cylinder 221 drives the transverse seat 222 to move back and forth. The lifting cylinder 211 is mounted on the transverse seat 222. In this way, the multiple push rods 10 are synchronously lifted and moved laterally, so that the push rods 10 can be moved to different positions for assembly operations.

[0057] Specifically, the clamp 212 includes a drive cylinder 213, a limiting cylinder 214, and two pneumatic jaws 215. The drive cylinder 213 drives the two pneumatic jaws 215 toward or away from each other. The limiting cylinder 214 is fixed to the drive cylinder 213 and located between the two pneumatic jaws 215. The two pneumatic jaws 215 are used to clamp the push rod 10, and the limiting cylinder 214 is used to limit the top end of the push rod 10. The two pneumatic jaws 215 achieve radial limitation of the push rod 10, and the limiting cylinder 214 achieves axial limitation of the push rod 10, thereby providing reliable pressure when the push rod 10 is inserted into the syringe 20.

[0058] The present invention can effectively control the direction and height of the push rod 10, improve the operability of the push rod 10, provide convenience for the next process, and the constant pressure assembly method is convenient and fast, saving processes, saving development costs, and improving product output and qualification rate.
