[0024] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] In related technologies, pre-filled syringe assembly equipment is used to assemble syringes and caps, achieving full automation of the assembly process and avoiding manual contact to ensure a sterile environment for the pre-filled syringes. Currently, in the automated assembly process, the caps need to be transferred and dispensed. During the dispensing process, misalignment or tilting of the caps can occur, affecting the subsequent transfer of caps and the accuracy of the alignment and assembly between the caps and the syringes, thus impacting the overall assembly efficiency of the pre-filled syringe assembly equipment.

[0026] To solve the above problems, please refer to... Figure 1 As shown, an embodiment of this application provides a pre-assembly device 100 for a pre-filled syringe cap, which includes a material dispensing mechanism 110, a mold closing mechanism 120, and a material feeding mechanism 130.

[0027] Specifically, in combination Figures 2 to 4As shown, the material distribution mechanism 110 is provided with a plurality of material distribution components 111 and a material blocking component 112. Each material distribution component 111 includes a material distribution channel 1111 and a pusher component 1112. The pusher component 1112 moves relative to the material distribution channel 1111. The material blocking component 112 is located at the output end of the material distribution channel 1111. The material release mechanism 130 can reciprocate between the output end of the material distribution channel 1111 and the mold closing mechanism 120. The material release mechanism 130 is provided with a plurality of first transfer grooves 1321, corresponding to a plurality of material distribution channels 1111. Each first transfer groove 1321 corresponds to a material distribution channel 1111. The pusher component 1112 is used to push the protective cap 210 to move on the material distribution channel 1111, thereby dispensing the pre-filled syringe. For example, the plurality of material distribution components 111 are arranged in parallel.

[0028] like Figure 2 and Figure 4 As shown, the material blocking assembly 112 reciprocates relative to the material distribution channel 1111 to be configured to have at least a first position A and a second position B. When in the first position A, the material blocking assembly 112 defines a plurality of limiting grooves 1123, which correspond to the material distribution channel 1111. When in the second position B, the material blocking assembly 112 defines a plurality of openings, through which the first material transfer groove 1321 corresponds to the material distribution channel 1111, so that the pusher 1112 can pass through the openings and move to the first material transfer groove 1321. The pusher 1112 can move relative to the material distribution channel 1111, and the pusher 1112 is used to push the protective cap 210 to move on the material distribution channel 1111. When the material stop assembly 112 is in the first position A, the pusher 1112 pushes the protective cap 210 into the corresponding limiting groove 1123. The material stop assembly 112 can standardize and position the protective cap 210 in the material distribution channel 1111, and check the position and posture of the protective cap 210. The material stop assembly 112 can switch to the second position B, and the pusher 1112 pushes the protective cap 210 through the opening of the material stop assembly 112, so as to push the protective cap 210 from the limiting groove 1123 into the first transfer groove 1321, reducing the situation of misalignment or skew in the position of the protective cap 210 when it is pushed into the first transfer groove 1321, ensuring the accuracy of the position and posture of the protective cap 210 when it is distributed, and improving the distribution efficiency. The material release mechanism 130 drives the protective cap 210 to move to the syringe 220 of the mold closing mechanism 120 to complete the pre-assembly of the pre-filled syringe.

[0029] As is easily understood, a pre-filled syringe is a disposable injection device that is pre-filled with drugs or vaccines and sterilized and sealed. It combines drug storage and direct injection functions and is widely used in fields such as biological products, antithrombotic drugs, vaccines, GLP-1 analogs, and cosmetic products.

[0030] For example, the pre-filled syringe cap pre-assembly device 100 also includes a feeding mechanism 140, which is used to convey the cap 210 to the position of the dispensing mechanism 110 so that the cap 210 can be pushed and dispensed through the dispensing channel 1111.

[0031] refer to Figure 1 , Figure 2 and Figure 4 As shown, the pre-filled syringe cap pre-assembly device 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X is taken as the length direction of the pre-filled syringe cap pre-assembly device 100, the second direction Y is taken as the width direction of the pre-filled syringe cap pre-assembly device 100, and the third direction Z is taken as the height direction of the pre-filled syringe cap pre-assembly device 100. The conveying direction of the dispensing channel 1111 is the first direction X. It is understood that the above definitions are only for the purpose of understanding the relative positional relationships of the various parts in the pre-filled syringe cap pre-assembly device 100 and should not be construed as limiting this application.

[0032] In one embodiment, alternatively, referencing Figure 3As shown, the baffle assembly 112 includes a first baffle plate 1121 and a second baffle plate 1122. The first baffle plate 1121 is disposed at the output end of the distributing channel 1111, and the second baffle plate 1122 is disposed on the side of the first baffle plate 1121 away from the distributing mechanism 110. The first baffle plate 1121 and the second baffle plate 1122 are arranged parallel to each other. The first baffle plate 1121 has a plurality of first openings 1121a along the second direction Y. The second baffle plate 1122 has a plurality of first openings 1121a along the second direction Y. A plurality of second openings 1122a are provided in the second direction Y. The first baffle plate 1121 and the second baffle plate 1122 can reciprocate along the second direction Y respectively. The dispensing channel 1111 is arranged along the first direction X. The protective cap 210 moves along the first direction X on the dispensing channel 1111. Correspondingly, the first baffle plate 1121 and the second baffle plate 1122 are respectively provided with a plurality of first openings along the width direction of the protective cap pre-assembly device 100 on the pre-filled syringe. 1121a and several second openings 1122a, wherein the first opening 1121a and the second openings 1122a can be at the same height. When the first baffle plate 1121 and the second baffle plate 1122a move along the width direction of the pre-filled syringe cap pre-assembly device 100, the first baffle plate 1121 can block the cap 210 on the dispensing channel 1111, or the cap 210 can pass through the first opening 1121 of the first baffle plate 1121. 21a, the second baffle plate 1122 can block the protective cap 210 on the material distribution channel 1111, or the protective cap 210 can pass through the second opening 1122a of the second baffle plate 1122, so that the first baffle plate 1121 and the second baffle plate 1122 form a first position A or a second position B during relative movement, so as to regulate and position the movement of the protective cap 210, which is beneficial for the feeding mechanism 130 to feed materials in the future and ensure the accuracy of the feeding position.

[0033] For example, refer to Figure 2 and Figure 3 As shown, multiple pushers 1112 can push multiple protective caps 210 to move. Each first transfer groove 1321 corresponds to a distribution channel 1111, and each distribution channel 1111 corresponds to a pusher 1112, so that multiple protective caps 210 can move to the corresponding positions of multiple first transfer grooves 1321 at the same time. Multiple pushers 1112 can operate synchronously without the need to control the pushing path of multiple pushers 1112 separately, thereby improving the flexibility and adaptability of pushing.

[0034] Optionally, such as Figure 4As shown, when in the first position A, any first opening 1121a cooperates with the second baffle plate 1122 to form a limiting groove 1123. Each limiting groove 1123 corresponds to a material distribution channel 1111. The first baffle plate 1121 and the second baffle plate 1122 of the baffle assembly 112 move relative to each other to form the first position A. The first opening 1121a of the first baffle plate 1121 and the second baffle plate 1122 define the limiting groove 1123. The pusher 1112 can push the protective cap 210 to move along the material distribution channel 1111, pushing the protective cap 210 to the position of the limiting groove 1123. The limiting groove 1123 is used to regulate and position the protective cap 210.

[0035] Optionally, such as Figure 5 As shown, when in the second position B, each first opening 1121a corresponds to a second opening 1122a to form an opening, and any opening corresponds to a material distribution channel 1111. The first baffle plate 1121 and the second baffle plate 1122 of the baffle assembly 112 move relative to each other to form the second position B. The pusher 1112 pushes the protective cap 210 through the second opening 1122a of the second baffle plate 1122. The protective cap 210 passes through the first opening 1121a and the second opening 1122a in sequence, pushing the protective cap 210 from the limiting groove 1123 to the first transfer groove 1321 position of the feeding mechanism 130, ensuring that the pusher 1112 pushes the protective cap 210 into the first transfer groove 1321 more accurately.

[0036] During the operation of the baffle assembly 112, the first baffle plate 1121 and the second baffle plate 1122 of the baffle assembly 112 move relative to each other to form a first position A. The first opening 1121a of the first baffle plate 1121 and the second baffle plate 1122 define a limiting groove 1123. The pusher 1112 can push the protective cap 210 along the material distribution channel 1111 to move the protective cap 210 to the position of the limiting groove 1123. The limiting groove 1123 is used to regulate and position the protective cap 210. When the protective cap 210 is detected to be in the limiting groove 1123, the baffle assembly 1122 will automatically adjust the position of the protective cap 210. After the arrival signal is received, the first baffle plate 1121 and the second baffle plate 1122 of the baffle assembly 112 move relative to each other to form the second position B. The pusher 1112 pushes the protective cap 210 through the second opening 1122a of the second baffle plate 1122. The protective cap 210 passes through the first opening 1121a and the second opening 1122a in sequence, pushing the protective cap 210 from the limiting groove 1123 to the first transfer groove 1321 of the feeding mechanism 130, ensuring that the pusher 1112 pushes the protective cap 210 into the first transfer groove 1321 more accurately.

[0037] In one embodiment, alternatively, referencing Figure 3 and Figure 6As shown, the feeding mechanism 130 includes a frame 131, a clamping assembly 132, and a rotating assembly 133. The clamping assembly 132 is rotatably connected to the frame 131 via the rotating assembly 133. The rotating assembly 133 is used to drive the clamping assembly 132 to rotate. The rotating assembly 133 can be a rotary cylinder. The clamping assembly 132 is provided with a first clamping member 1322 and a second clamping member 1323. The first clamping member 1322 and the second clamping member 1323 can be separated from each other, that is, the first clamping member 1322 and the second clamping member 1323 are in a clamping state or a separated state. When the first clamping member 1322 and the second clamping member 1323 are separated, it is convenient for the protective cap 210 to enter the corresponding position between them, or the first clamping member 1322 and the second clamping member 1323 can be separated from each other. Two clamping members 1323 approach each other and define a plurality of first transfer grooves 1321. Each first transfer groove 1321 corresponds to a material distribution channel 1111. Each protective cap 210 moves on a material distribution channel 1111, so that the protective cap 210 enters the preset position of the corresponding first transfer groove 1321 through the material distribution channel 1111. The control cylinder can drive the first clamping member 1322 or the second clamping member 1323 to move, so that the first clamping member 1322 and the second clamping member 1323 approach each other to clamp and fix the protective cap 210. Of course, the first clamping member 1322 and the second clamping member 1323 are in a clamping state so that the rotating component 133 can be started to rotate the clamping component 132, ensuring the automated operation of assembly and unloading.

[0038] Further, refer to Figure 6As shown, the first clamping member 1322 is provided with a plurality of first transfer portions 1324, and the second clamping member 1323 is provided with a plurality of second transfer portions 1325. The first clamping member 1322 and the second clamping member 1323 are arranged parallel to each other and vertically. The first transfer portions 1324 extend toward the second transfer portions 1325 and are coplanar with the second transfer portions 1325. When the first clamping member 1322 and the second clamping member 1323 approach each other, each first transfer portion 1324 and one second transfer portion 1325 approach each other and define a first transfer groove 1321. In other words, the first clamping member 1322 and the second clamping member 1323 move vertically along the third direction Z. The first transfer portion 1324 of the first clamping member 1322 corresponds to the second transfer portion 1325 of the second clamping member 1323 and is located on the same plane. When the first clamping member 1322 and the second clamping member 1323 jointly clamp the cap 210, the first transfer portion 1324 and the second transfer portion 1325 are located on the same plane to clamp the opposite sides of the cap 210, ensuring the clamping stability of the cap 210 and reducing tilting or skewing caused by uneven clamping force on the cap 210. When the first clamping member 1322 and the second clamping member 1323 are separated, the first clamping member 1322 and the second clamping member 1323 are arranged vertically to avoid motion interference between them, which has a better technical effect.

[0039] In addition, since the protective cap 210 is made of fragile materials such as glass, in order to avoid the protective cap 210 being damaged by excessive clamping force, it is necessary to control the clamping force to an appropriate level and try not to increase the clamping force to ensure that the protective cap 210 is always in a clamped state. This not only ensures the stability of clamping the protective cap 210, but also prevents the protective cap 210 from breaking or being damaged.

[0040] The first clamping member 1322 is also provided with a second material transfer groove 1326. The second material transfer groove 1326 of the first clamping member 1322 is used to initially engage and limit the cap 210, so that the first clamping member 1322 and the second clamping member 1323 can move relative to each other to clamp the cap 210. When the clamping assembly 132 rotates 180° through the rotating assembly 133, the first clamping member 1322 and the second clamping member 1323 can separate from each other to release the cap 210. At this time, the cap 210 will detach from the second material transfer groove 1326 under its own weight.

[0041] For example, such as Figure 6 As shown, multiple first transfer grooves 1321 are arranged along the second direction Y, and the rotation axis of the clamping assembly 132 is in the second direction Y, that is, the rotation axis of the clamping assembly 132 is parallel to the arrangement direction of the multiple first transfer grooves 1321.

[0042] Optionally, refer to Figure 1 and Figure 6 As shown, the feeding mechanism 130 also includes a first lifting component 134. The frame 131 is provided with a slide rail 1311 along the third direction Z. The first lifting component 134 is slidably connected to the slide rail 1311. The side of the first lifting component 134 away from the slide rail 1311 is fixedly connected to the rotating component 133. The first lifting component 134 can drive the clamping component 132 to rise or fall. After the clamping component 132 clamps the protective cap 210 at the position of the stop component 112, on the one hand, by raising the clamping component 132, the clamping component 132 is moved away from the stop component 112, reserving a certain rotation space for the rotation of the clamping component 132. The protective cap 210 clamped on the clamping component 132 is moved to the position of the corresponding mold closing mechanism 120. This avoids the clamping component 132 from interfering with or affecting the stop component 112 or the mold closing mechanism 120 during rotation, ensuring the accuracy of the movement. On the other hand, it makes the overall structure more compact and the space utilization rate higher.

[0043] In one embodiment, alternatively, referencing Figure 3 and Figure 8 As shown, the mold clamping mechanism 120 includes a first mold clamping assembly 121 and a second mold clamping assembly 122 disposed opposite to each other. The first mold clamping assembly 121 includes a mold clamping platform 1211, a second lifting assembly 1212, and a vibrating element 1213. The vibrating element 1213 is connected to the mold clamping platform 1211. The second lifting assembly 1212 is drive-connected to the mold clamping platform 1211, so that the mold clamping platform 1211 moves closer to or further away from the second mold clamping assembly 122 along a third direction Z. The clamping assembly 132 releases the clamp. The protective cap 210 is held and falls to the corresponding position on the mold-forming platform 1211. The vibrating element 1213 is connected to the mold-forming platform 1211 to generate vibration on the mold-forming platform 1211, which facilitates the initial assembly of the protective cap 210 on the mold-forming platform 1211 and the syringe on the second mold-forming assembly 122. The second lifting assembly 1212 is used to drive the mold-forming platform 1211 to rise or fall along the third direction Z to adjust the relative position between the mold-forming platform 1211 and the second mold-forming assembly 122.

[0044] As is readily understood, the vibrating element 1213 is a tool that generates vibration mechanically. It can generate high-frequency micro-amplitude vibration through a driving source such as a high-speed rotating eccentric oscillator or electromagnetic force. For example, the vibrating element 1213 can be an electromagnetic vibrator or a pneumatic vibrator, driven by a motor to achieve high-frequency vibration. In this application, the vibrating element 1213 generates high-frequency vibration to cause the protective cap 210 on the film-forming table 1211 to fall off.

[0045] Further, refer to Figure 8 and Figure 9As shown, the mold-closing platform 1211 is provided with a plurality of mold-closing holes 1211a and a third baffle plate 1211b. The second mold-closing assembly 122 is provided with a third clamping member 1221. The mold-closing holes 1211a can correspond to the first material transfer groove 1321. The third baffle plate 1211b is disposed between the mold-closing platform 1211 and the third clamping member 1221. The third baffle plate 1211b is pulsatorically connected to the mold-closing platform 1211. The third baffle plate 1211b can move closer to the mold-closing platform 1211 along the first direction X to block the mold-closing holes 1211a, or the third baffle plate 1211b can move away from the mold-closing platform 1211. The mold stage 1211 exposes the mold closing hole 1211a to the outside. The second mold closing assembly 122 is provided with several third clamping members 1221, which are used to clamp the syringe 220. Each mold closing hole 1211a corresponds to one third clamping member 1221. The third baffle plate 1211b can close the mold closing hole 1211a to facilitate the support of the protective cap 210. The first material transfer groove 1321 of the clamping assembly 132 can release the protective cap 210 so that the protective cap 210 falls into the corresponding mold closing hole 1211a of the mold closing stage 1211. In scenarios where the protective cap 210 needs to be assembled, such as... Figure 6 As shown, the third baffle plate 1211b is away from the mold closing platform 1211, allowing the protective cap 210 to fall from below the mold closing hole 1211a. Under the action of the vibrating element 1213, the protective cap 210, which falls into the mold closing hole 1211a, falls under its own weight and is initially assembled with the syringe 220 on the second mold closing assembly 122, so that the needle of the syringe 220 pierces the protective cap 210.

[0046] In summary, the pusher 1112 of the pre-filled syringe cap pre-assembly device 100 can move relative to the dispensing channel 1111. The pusher 1112 is used to push the cap 210 to move on the dispensing channel 1111, thereby dispensing the pre-filled syringe. When the stop assembly 112 is in the first position A, the pusher 1112 pushes the cap 210 into the corresponding limiting groove 1123. The stop assembly 112 can regulate and position the cap 210 in the dispensing channel 1111, and control the position of the cap 210. The material stop assembly 112 can be switched to the second position B. The pusher 1112 pushes the protective cap 210 through the opening of the material stop assembly 112 so that the protective cap 210 can be pushed from the limiting groove 1123 into the first transfer groove 1321. This reduces the possibility of misalignment or skewness of the protective cap 210 when it is pushed into the first transfer groove 1321, ensuring the accuracy of the position and posture of the protective cap 210 when it is being distributed, and improving the distribution efficiency. The unloading mechanism 130 drives the protective cap 210 to move to the syringe 220 of the mold closing mechanism 120 to complete the pre-assembly of the pre-filled syringe, thereby improving the assembly efficiency.

The assembly system can be used to assemble the caps 210 and syringes 220 of the pre-filled syringe.
