Description

Technical Field

[0001] This invention relates to the field of syringe assembly, and in particular to a syringe assembly system. Background Technology

[0002] Existing syringes consist of a syringe barrel and a piston rod. The piston rod includes a shaft and a rubber piston fitted onto the front end of the shaft. The assembly of existing syringes is mostly done manually. During assembly, the rubber head is first assembled to the front end of the shaft to form the piston rod, and then the piston rod is inserted into the syringe barrel to complete the assembly of the syringe.

[0003] Assembling syringes manually is inefficient and causes significant fatigue; the large amount of manpower required also increases labor costs. Therefore, it is essential to provide a syringe assembly system to replace manual syringe assembly to address these issues. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems by providing a syringe assembly system that can replace manual labor in assembling syringes, thereby improving assembly efficiency and reducing human fatigue.

[0005] The technical solution adopted in this invention is as follows:

[0006] A syringe assembly system includes a shaft storage device, a moving tray, a piston rod assembly device, a shaft moving device, a piston rod storage device, a syringe storage device, a piston rod moving device, a syringe moving device, and a syringe assembly device.

[0007] The pole storage device is used to hold the pole.

[0008] The movable tray is used to place the rubber piston and deliver the rubber piston to the piston rod assembly equipment;

[0009] The piston rod assembly equipment is used to assemble the rod body and the rubber piston together to form a piston rod;

[0010] The rod body moving device is used to deliver the rod body on the rod body temporary storage device to the piston rod assembly device, and to deliver the piston rod on the piston rod assembly device to the piston rod temporary storage device;

[0011] The piston rod temporary storage device is used to hold the piston rod;

[0012] The syringe storage device is used to hold syringes;

[0013] The piston rod moving device is used to deliver the piston rod in the piston rod temporary storage device to the syringe assembly device;

[0014] The syringe mobile device is used to deliver syringes from the syringe temporary storage device to the syringe assembly device;

[0015] The syringe assembly equipment is used to assemble the piston rod and the syringe together.

[0016] Due to the aforementioned structure, during syringe assembly, the shaft is first placed on the shaft storage device, the rubber piston is placed on the moving tray, and the syringe is placed on the syringe storage device. Then, the shaft movement device transports the shaft to the piston rod assembly device, and the moving tray transports the rubber piston to the piston rod assembly device. The piston rod assembly device then assembles the rubber piston and shaft together to form the piston rod. The shaft movement device then transports the assembled piston rod to the piston rod storage device, which in turn transports the piston rod to the syringe assembly device. The syringe movement device then transports the syringe to the syringe assembly device, where the piston rod and syringe are assembled together, completing the syringe assembly. The presence of the shaft storage device, piston rod storage device, and syringe storage device allows the shaft, piston rod, and syringe to be placed in specific positions, facilitating clamping by the shaft movement device, piston rod movement device, and syringe movement device.

[0017] The syringe assembly system of the present invention can conveniently and quickly replace manual assembly of syringes, improve the assembly efficiency of syringes, reduce human fatigue, and save labor costs.

[0018] Furthermore, the piston rod assembly equipment includes a rod positioning device and a rod pressing device;

[0019] The pole positioning device is located above the movable tray. The pole positioning device includes a pole clamping mechanism and a lifting mechanism for the pole clamping mechanism. The lifting mechanism for the pole clamping mechanism is used to drive the pole clamping mechanism to move up and down.

[0020] The rod pressing mechanism includes a pressing head and a pressing head lifting mechanism. The pressing head is located above the rod clamping mechanism and the pressing head lifting mechanism is used to drive the pressing head to move up and down.

[0021] Due to the aforementioned structure, during piston rod assembly, the rod body moving device first sends the rod body from the rod body temporary storage platform to the rod body positioning device, causing the rod body clamping mechanism to vertically clamp the rod body with the front end facing downwards and the rear end facing upwards. Then, the lifting mechanism of the rod body clamping mechanism moves the rod body clamping mechanism downwards, bringing the front end of the rod body close to the tray and aligning it with the assembly hole of the rubber piston placed on the tray. Then, under the action of the pressing head lifting mechanism, the pressing head moves downwards, pressing the rear end of the rod body and pushing the rod body downwards, so that the front end of the rod body is inserted into the assembly hole of the rubber piston, completing the piston rod assembly. To ensure that the pressing head can push the rod body downwards, the rod body clamping mechanism cannot clamp the rod body too tightly. The presence of the rod body positioning device ensures the stability of the rod body position and the alignment of the rod body with the rubber piston; the presence of the rod body pressing device ensures that the piston rod can be stably inserted into the assembly hole of the rubber piston.

[0022] Furthermore, the movable pallet includes a pallet and a pallet moving mechanism disposed at the bottom of the pallet; the pallet moving mechanism is used to move the pallet in the horizontal direction and adjust the position of the pallet below the pole positioning device.

[0023] Due to the above structure, the tray can stably hold the rubber piston, facilitating the assembly of the rod and the rubber piston; and because the tray moving mechanism can easily adjust the position of the tray, it can ensure that the rubber piston on the tray is aligned with the rod positioning device, ensuring the accuracy of the assembly.

[0024] Furthermore, the pole body moving device includes a pole body clamping mechanism two and a pole body clamping mechanism two moving mechanism; the pole body clamping mechanism two moving mechanism is used to drive the pole body clamping mechanism two to move, so that the pole body clamping mechanism two clamps the pole body on the pole body temporary storage device and sends the pole body to the pole body positioning device, and the pole body clamping mechanism two moving mechanism is used to drive the pole body clamping mechanism two to move, so that the pole body clamping mechanism two clamps the piston rod on the pole body positioning device and sends the piston rod to the piston rod temporary storage device.

[0025] The presence of the shaft moving device makes it easy to deliver the shaft and piston rod to various devices.

[0026] Furthermore, the syringe assembly equipment includes a piston rod platform, a piston rod clamping mechanism, a piston rod platform moving mechanism, a syringe platform, a syringe clamping mechanism, a syringe platform moving mechanism, and a push rod mechanism.

[0027] The piston rod platform moving mechanism is located at the bottom of the piston rod platform and is used to drive the piston rod platform closer to the syringe platform.

[0028] The piston rod clamping mechanism is located on the top of the piston rod platform and is used to horizontally clamp the piston rod on the piston rod platform.

[0029] The syringe stage moving mechanism is located at the bottom of the syringe stage and is used to drive the syringe stage closer to the piston rod stage.

[0030] The syringe clamping mechanism is located on the top of the syringe platform and is used to horizontally clamp the syringe on the syringe platform.

[0031] A push rod mechanism is provided on the piston rod platform. The push rod mechanism pushes the piston rod to move towards the syringe, so that the front end of the piston rod is inserted into the syringe.

[0032] Due to the above structure, the piston rod is placed on the piston rod platform, and the syringe is placed on the syringe platform. The piston rod platform and the syringe platform first approach each other, and then the push rod mechanism pushes the piston rod to insert into the syringe, thus completing the assembly of the syringe.

[0033] Furthermore, the push rod mechanism includes a push rod head disposed at the rear end of the piston rod clamping mechanism. The push rod head is connected to a push rod head moving mechanism, which is used to push the push rod head to move, so that the push rod head pushes the piston rod to insert into the syringe.

[0034] Furthermore, the piston rod mobile device includes a piston rod clamping mechanism two and a piston rod clamping mechanism two moving mechanism. The piston rod clamping mechanism two moving mechanism is used to drive the piston rod clamping mechanism two to move, so that the piston rod clamping mechanism two clamps the piston rod on the piston rod temporary storage device and sends the piston rod to the piston rod platform.

[0035] The syringe mobile device includes a syringe clamping mechanism two and a syringe clamping mechanism two moving mechanism. The syringe clamping mechanism two moving mechanism is used to drive the syringe clamping mechanism two to move, so that the syringe clamping mechanism two clamps the syringe on the syringe temporary storage device and sends the syringe to the syringe carrier.

[0036] Furthermore, the pole storage device includes a pole clamping mechanism three, a pole clamping mechanism three moving mechanism, and a pole flipping mechanism; the pole clamping mechanism three is mounted on the pole flipping mechanism, and the pole flipping mechanism is used to drive the pole clamping mechanism three to rotate in the vertical plane; the pole flipping mechanism is mounted on the pole clamping mechanism three moving mechanism, and the pole clamping mechanism three moving mechanism is used to drive the pole clamping mechanism three to move.

[0037] The presence of the rod body flipping mechanism allows the rod body clamped on the rod body clamping mechanism three to rotate in the vertical plane, enabling the rod body to be vertically clamped on the rod body temporary storage device. This facilitates the vertical delivery of the rod body to the piston rod assembly device, making it convenient for the rod body to be assembled with the rubber piston. Furthermore, the moving mechanism of the rod body clamping mechanism three can drive the rod body to move, making it convenient to adjust the position of the rod body and to move the rod body to clamp it.

[0038] The piston rod temporary storage device includes a piston rod clamping mechanism three, a piston rod clamping mechanism three moving mechanism, and a piston rod flipping mechanism; the piston rod clamping mechanism three is mounted on the piston rod flipping mechanism, and the piston rod flipping mechanism is used to drive the piston rod clamping mechanism three to rotate in a vertical plane; the piston rod flipping mechanism is mounted on the piston rod clamping mechanism three moving mechanism, and the piston rod clamping mechanism three moving mechanism is used to drive the piston rod clamping mechanism three to move;

[0039] Since the piston rod is in a vertical position when it is removed from the piston rod assembly equipment, it needs to be set horizontally in order to facilitate the assembly of the syringe assembly equipment. Therefore, due to the existence of the piston rod flipping mechanism, the piston rod can be placed horizontally on the piston rod temporary storage equipment. Since the piston rod clamping mechanism and the three moving mechanism can drive the piston rod to move, it is convenient to adjust the position of the piston rod and to facilitate the piston rod mobile equipment to clamp the piston rod.

[0040] The syringe storage device includes a syringe clamping mechanism three and a syringe clamping mechanism three moving mechanism; the syringe clamping mechanism three is used to clamp syringes; the syringe clamping mechanism three moving mechanism is used to drive the syringe clamping mechanism three to move.

[0041] Due to the above structure, the three moving mechanisms of the syringe clamping mechanism can drive the movable syringe to move, which facilitates adjusting the position of the syringe and facilitates the clamping of the syringe by the syringe moving equipment.

[0042] Furthermore, the syringe assembly system also includes a sterilization device; the rod moving device is used to deliver the piston rod on the piston rod assembly device to the sterilization device for sterilization.

[0043] Furthermore, the syringe assembly system also includes a shaft loading device and a syringe loading device; the shaft loading device is used to deliver the shaft to the shaft temporary storage device; the syringe loading device is used to deliver the syringe to the syringe temporary storage device.

[0044] The presence of the rod loading equipment and the syringe loading equipment facilitates the loading of materials for the entire system, further improving assembly efficiency.

[0045] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0046] The syringe assembly system of this invention can conveniently and quickly replace manual syringe assembly, improving assembly efficiency, reducing manual fatigue, and saving labor costs. Simultaneously, the presence of a sterilization device ensures the cleanliness of the syringes and guarantees their safe use. Attached Figure Description

[0065] The pole body loading device 13 is used to send the pole body to the pole body temporary storage device 1;

[0066] The pole body temporary storage device 1 allows the pole body to be placed vertically on the pole body temporary storage device 1, and the pole body temporary storage device 1 can drive the pole body to move;

[0067] The movable tray 10 is used to place the rubber piston and deliver the rubber piston to the piston rod assembly equipment;

[0068] The piston rod assembly equipment is used to assemble the rod body and the rubber piston together to form a piston rod;

[0069] The sterilization device 3 is used to sterilize the piston rod;

[0070] The rod body moving device 11 is used to drive the rod body on the rod body temporary storage device 1 to move, so that the rod body can be sent to the piston rod assembly device, the sterilization device 3 and the piston rod temporary storage device 8 respectively;

[0071] The piston rod temporary storage device 8 allows the piston rod to be placed horizontally on the piston rod temporary storage device 8, and the piston rod temporary storage device 8 can drive the piston rod to move;

[0072] The syringe feeding device 14 is used to feed the syringes to the syringe storage device 7;

[0073] The syringe storage device 7 allows the syringe to be placed horizontally on the syringe storage device 7, and the syringe storage device 7 can move the syringe.

[0074] The piston rod moving device 4 is used to deliver the piston rod on the piston rod temporary storage device 8 to the syringe assembly device 5.

[0075] The syringe mobile device 6 is used to deliver the syringes on the syringe temporary storage device 7 to the syringe assembly device 5.

[0076] The syringe assembly device 5 is used to assemble the piston rod and the syringe together.

[0077] During syringe assembly, the shaft is first fed to the shaft storage device 1 by the shaft loading device 13, and the syringe is fed to the syringe storage device 7 by the syringe loading device 14. The rubber piston is then placed on the moving tray 10. The shaft moving device 11 then sends the shaft to the piston rod assembly device, and the moving tray 10 sends the rubber piston to the piston rod assembly device. The piston rod assembly device then assembles the rubber piston and shaft together to form the piston rod. The shaft moving device 11 then sends the assembled piston rod to the sterilization device 3 for sterilization. The sterilized piston rod is then sent to the piston rod storage device 8, so that the piston rod moving device 4 can send the piston rod to the syringe assembly device 5. After the syringe moving device 6 sends the syringe to the syringe assembly device 5, the syringe assembly device 5 can assemble the piston rod and syringe together, completing the assembly of the entire syringe.

[0078] The syringe assembly system of the present invention can conveniently and quickly replace manual assembly of syringes, improve the assembly efficiency of syringes, reduce human fatigue, and save labor costs.

[0079] Furthermore, the piston rod assembly equipment includes a rod positioning device 2 and a rod pressing device 9;

[0080] The pole positioning device 2 is located above the movable tray 10. The pole positioning device 2 includes a pole clamping mechanism 201 and a pole clamping mechanism lifting mechanism.

[0082] Due to the above structure, during piston rod assembly, the rod body moving device 11 first sends the rod body from the rod body temporary storage platform to the rod body positioning device 2, so that the rod body clamping mechanism 201 clamps the rod body vertically, with the front end of the rod body facing down and the rear end facing up; then the rod body clamping mechanism 201 moves down, so that the front end of the rod body is close to the tray 1001 and aligned with the assembly hole of the rubber piston placed on the tray 1001; then the pressing head 901 moves down under the action of the pressing head lifting mechanism 902, so that the pressing head 901 presses the rear end of the rod body, pushes the rod body down, and inserts the front end of the rod body into the assembly hole of the rubber piston, thus completing the piston rod assembly. In order to ensure that the pressing head 901 can push the rod body down, the rod body clamping mechanism 201 should not clamp the rod body too tightly. The presence of the rod positioning device 2 ensures the stability of the rod position and the alignment of the rod with the rubber piston; the presence of the rod pressing device 9 ensures that the piston rod can be stably inserted into the assembly hole of the rubber piston.

[0084] Due to the above structure, the tray 1001 can stably place the rubber piston, which facilitates the assembly of the rod and the rubber piston; since the tray moving mechanism can easily adjust the position of the tray 1001, it can ensure that the rubber piston on the tray 1001 is aligned with the rod positioning device 2, thus ensuring the accuracy of the assembly.

Under the action of the guide rod 202, the connecting nut 204 moves up and down on the output shaft of the pole clamping mechanism lifting motor 203, thereby driving the entire pole clamping mechanism 201 to move up and down. The pole clamping mechanism 201 can be an existing pneumatic manipulator.

The rod flipping mechanism and the piston rod flipping mechanism 802 are both flipping motors.

[0112] The rod clamping mechanism with three moving parts and the piston rod clamping mechanism with three moving parts 803 can be either cylinders or lead screw transmission mechanisms. For example... Figure 16As shown, the structure of the piston rod temporary storage device 8 is used to illustrate that the rod clamping mechanism 3-moving mechanism and the piston rod clamping mechanism 3-moving mechanism 803 are screw drive mechanisms.

A plurality of left claws 20 are evenly spaced on the left claw mounting rod 21, and a plurality of right claws 19 are evenly spaced on the right claw mounting rod 18. A left slider 22 is connected to the left claw mounting rod 21, and a right slider 17 is connected to the right claw mounting rod 18. The left slider 22 and right slider 17 are connected to a double-headed cylinder 16. The double-headed cylinder 16 drives the left slider 22 and right slider 17 to move closer or further apart, causing the left claws 20 on the left claw mounting rod 21 and the right claws 19 on the right claw mounting rod 18 to move closer or further apart, thus completing the clamping of the rod body, piston rod, and syringe.
