Description

Technical Field

[0001] This invention relates to the field of machinery, and more specifically to an injection system. Background Technology

[0002] Micromolding is a high-precision nanofabrication technology that uses micro-replicating molds to form microstructures. Micromolding has advantages such as high replication accuracy, low cost, and low residual stress, and it is widely used in the fabrication of nanostructures such as microgears, microneedles, microfluidic chips, and light guide plates in various fields such as machinery, medicine, and biology.

[0003] The most critical step in micromolding is mold filling, which involves filling the mold cavity with a high-fill-ratio replicating liquid material. This is a key factor affecting the accuracy of microstructure replication. Common mold filling methods include pressure filling and vacuum filling. Pressure filling involves using pressure to force the filler material into the mold cavity. For this, the mold is usually manufactured using a one-piece metal forming method. However, it is very difficult to process structures with equal aspect ratios and high precision, such as microneedle molds, using a one-piece metal forming method. Therefore, microneedle molds are often made of silicon or polymer materials. However, silicon is usually brittle, and polymer materials are relatively soft, requiring strict compressive stress, making them unsuitable for mass production. In contrast, vacuum filling has lower requirements for mold material and size compatibility, offering more obvious advantages and wider applications. Current vacuum filling methods typically involve spreading the raw material evenly on the surface of the mold under normal pressure, then drawing a vacuum to remove residual gas inside the mold, allowing the raw material to enter the interior of the mold's microstructure. However, this method has several problems. For example, if the raw material layer is thick, the process of removing residual gas through vacuuming may result in incomplete removal, leaving residual gas in the raw material and ultimately causing air bubbles in the product, affecting product quality. Furthermore, a thicker layer also leads to material waste, increasing production costs. Conversely, if the raw material layer is too thin, after vacuuming to remove residual gas, some material may enter the molding cavity but not completely fill it, resulting in material shortages and affecting product performance. In addition, uneven material layering can easily occur, with some areas being thicker than others, or the mold surface being uneven. These issues all affect the consistency of material entering the molding cavity, ultimately impacting product quality. Moreover, the longer time it takes for the raw material to penetrate the microstructure reduces production efficiency. Summary of the Invention

[0035] Compared with the prior art, the infusion system of the present invention has the following advantages:

[0036] The aforementioned injection system is used to inject raw materials into a mold, the mold including a base and a plurality of molding cavities disposed on the base; the injection system includes a housing, a vacuum generating system, a stage assembly, an injection assembly, and a motion mechanism, the housing having a first sub-cavity formed thereon, the first sub-cavity selectively communicating with or isolating from the environment outside the first sub-cavity; the vacuum generating system is used to evacuate the first sub-cavity; the stage assembly includes a first stage disposed in the first sub-cavity and used to support the mold; the injection assembly includes a raw material reservoir and an injection port, the injection port communicating with the raw material reservoir; the motion mechanism includes a first motion mechanism, the first motion mechanism being at least partially disposed in the first sub-cavity and used to control relative movement between the first stage and the injection assembly along a first direction and / or a second direction, such that the injection port is selectively aligned with one of the molding cavities, the first motion mechanism also being used to control the injection assembly to perform reciprocating linear movement along a third direction, such that the injection port moves closer to or away from the molding cavity; any two of the first direction, the second direction, and the third direction are perpendicular to each other. When using the injection system to inject raw materials into the mold in the first sub-cavity, the first sub-cavity is first evacuated. Then, the injection port and the first stage are moved relative to each other in the first direction and / or the second direction. When the injection port is aligned with one of the molding cavities, the injection assembly is controlled to move in the negative direction of the third direction so that the injection port is closer to the mold. Raw materials are then filled into the molding cavity using the injection port. Next, the injection assembly and the first stage are again moved relative to each other in the first direction and / or the second direction so that the injection port is aligned with another molding cavity that has not been evacuated, and raw materials are filled into that cavity using the injection port. When all the molding cavities on the mold are filled with raw materials, the injection assembly is controlled to move in the positive direction of the third direction so that the injection assembly is moved away from the mold. This filling method allows the injection assembly to directly inject raw materials into each molding cavity under vacuum conditions. The raw materials can accurately enter each molding cavity, reducing waste. Furthermore, the direct entry of raw materials into the molding cavity, without the need for slow seepage, shortens filling time and reduces production costs. Even if the raw materials are not fully injected into the molding cavity during the injection process, the pressure difference between the inside and outside of the molding cavity can be used to completely force the raw materials into the cavity during the removal of the mold (a process that breaks the vacuum for the mold). This avoids insufficient filling in each molding cavity, improves the consistency of raw material filling, and enhances the quality of the final product.Furthermore, the use of the injection port allows the raw material to be sprayed out in the form of water droplets. In actual use, the operating parameters of the injection port can be set according to the opening size of the molding cavity, so that the diameter of the raw material sprayed from the injection port is smaller than the opening size of the molding cavity. This allows the raw material to be smoothly injected into the molding cavity, avoiding waste caused by the raw material being sprayed outside the molding cavity. The number of times the injection port sprays raw material into each molding cavity is set according to the volume of the molding cavity, thereby ensuring the sufficiency and consistency of the raw material filling and improving the production quality.

[0037] Furthermore, the housing also has a second sub-cavity, which is selectively connected to or isolated from the environment outside the housing, and a second mold transfer position is provided in the second sub-cavity; the first sub-cavity is selectively connected to or isolated from the second sub-cavity, and a first mold transfer position is provided in the first sub-cavity, and the first platform can be placed at the first mold transfer position; the vacuum generating system is also used to evacuate the second sub-cavity; the platform assembly also includes a second platform, which is used to be placed in the second sub-cavity, and a plurality of mold placement positions are provided on the second platform; the motion mechanism also includes a second motion mechanism and a third motion mechanism, the second motion mechanism is at least partially disposed in the second sub-cavity, and is used to control the movement of the second platform so that the second platform enters the second sub-cavity or at least partially extends out of the housing, and selectively makes one of the mold placement positions coincide with the second mold transfer position; the third motion mechanism is used to transfer the mold between the mold placement position on the second platform that coincides with the second mold transfer position and the second platform located at the first mold transfer position. This configuration allows for the simultaneous unloading of a mold that has already undergone vacuum filling and the loading of a mold that has not yet undergone vacuum filling during the vacuum filling process of a mold. In other words, it enables some steps in the entire production process to be executed synchronously, thereby increasing the production cycle and further improving production efficiency.

The same or similar reference numerals in the drawings represent the same or similar parts.

[0064] Figure 1 and Figure 2A schematic diagram of the infusion system provided in an embodiment of the present invention is shown. Figure 1 and Figure 2 As shown, the infusion system includes a housing 1000, a vacuum generating system 2000, a stage assembly 3000, an infusion assembly 4000, and a motion mechanism 5000. The housing 1000 forms a first sub-cavity 1001, which is selectively connected to or isolated from the environment outside the first sub-cavity 1001. The vacuum generating system 2000 is used to evacuate the first sub-cavity 1001. The stage assembly 3000 includes a first stage 3100, which is disposed in the first sub-cavity 1001 and used to support the mold 200. The infusion assembly 4000 includes a raw material tank 4100 and an infusion port 4200, which communicates with the raw material tank 4100. The motion mechanism 5000 includes a first motion mechanism 5100, which is at least partially disposed in the first sub-cavity 1001 and is used to control relative motion between the first stage 3100 and the infusion assembly 4000 along a first direction and / or a second direction. The first motion mechanism 5100 is also used to control the infusion assembly 4000 to perform reciprocating linear motion along a third direction. Any two of the first direction, the second direction, and the third direction are perpendicular to each other. Typically, the first direction and the second direction are horizontal, and the third direction is vertical. In this embodiment of the invention, the first direction may be... Figure 1 and Figure 2 The X-axis in the coordinate system extends in the first direction, and the positive direction of the X-axis is the positive direction of the first direction (i.e., the direction indicated by the arrow on the X-axis in the diagram). The second direction can be the Y-axis, extending in the first direction, and the positive direction of the Y-axis (the direction indicated by the arrow on the Y-axis in the diagram) is the positive direction of the second direction. The third direction can be the Z-axis, extending in the second direction, and the positive direction of the Z-axis (the direction indicated by the arrow on the Z-axis in the diagram) is the positive direction of the third direction. The positive direction of the Z-axis is vertically upward, and the negative direction of the Z-axis is vertically downward. Therefore, when referring to the X-direction or the direction of the X-axis in the following text, it can refer to the first direction; when referring to the Y-direction or the direction of the Y-axis, it can refer to the second direction; and when referring to the Z-direction or the direction of the Z-axis, it can refer to the third direction.

[0065] Figure 3 A schematic diagram of the structure of a mold 200 is shown. For example... Figure 3 As shown, the mold 200 includes a base 210, a recess 220 is provided on the base 210, and a plurality of molding cavities 230 are provided in the recess 220, and the plurality of molding cavities 230 are arranged in an array.

[0066] When the injection system is used to vacuum inject raw materials into the mold 200, the mold 200 is placed on the first stage 3100, and the first sub-cavity 1001 is in a vacuum environment. Then, when the first motion mechanism 5100 controls the relative movement between the first stage 3100 and the injection assembly 4000 in the X and / or Y directions, the injection port 4200 of the injection assembly 4000 can be selectively aligned with a molding cavity 230 (i.e., the injection port 4200 and the aligned molding cavity 230 have the same coordinates in the XY plane). Then, the first motion mechanism 5100 controls the injection assembly 4000 to move in the negative Z direction so that the injection port 4200 is close to the mold 200, and then raw materials can be injected into the molding cavity 230. The specific filling process is as follows: the filling component 4000 first fills the molded cavity with raw material, and then controls the relative movement between the filling component 4000 and the first stage 3100 in the X and / or Y directions, so that the filling port 4200 is aligned with another molded cavity 230 that has not been vacuum-filled, and fills it with raw material. That is, after each molded cavity is filled with raw material, the relative movement between the filling component 4000 and the first stage 3100 in the X and / or Y directions is controlled again, so that the filling port 4200 is aligned with the next molded cavity 230 that has not been vacuum-filled, and fills it with raw material, until all the molded cavities 230 on the mold 200 are filled with raw material. Finally, the first motion mechanism 5100 controls the filling component 4000 to move in the positive direction of the Z axis, so that the filling port 4200 moves away from the mold 200. This filling method allows for accurate filling of each molding cavity, reducing material waste. The material enters the molding cavity directly without slow seepage, shortening filling time and reducing production costs. Furthermore, even if the material is not fully injected into the molding cavity during the pouring process, the pressure difference between the inside and outside of the molding cavity 230 can be used to completely inject the material into the cavity while the mold is being removed from the housing 1000 (a process that breaks the vacuum for the mold). This avoids insufficient filling in each molding cavity 230, improves the consistency of material filling, and enhances the quality of the final product.Furthermore, the filling port 4200 allows the raw material to be sprayed out in a droplet shape. In actual use, the operating parameters of the filling port 4200 can be set according to the opening size of the molding cavity 230, so that the diameter of the raw material sprayed from the filling port 4200 is smaller than the opening size of the molding cavity 230. This allows the raw material to be smoothly poured into the molding cavity 230, avoiding waste caused by raw material being sprayed outside the molding cavity 230. The number of times the filling port sprays raw material into each molding cavity 230 is set according to the volume of the molding cavity 230, thereby avoiding insufficient filling in each molding cavity 230, improving the consistency of raw material filling, and improving the quality of the final product. Preferably, the filling port 4200 is a pin-type nozzle.

[0067] It should be noted that any suitable device or method can be used in the embodiments of the present invention to determine whether the filling port 4200 is aligned with a molding cavity 230. For example, when the filling system is started for the first time, the relative motion function of the first motion mechanism 5100 is first used to determine the relative positional relationship between the filling port 4200 and the first molding cavity 230, and the filling port 4200 sprays raw material once, and it is observed whether the raw material accurately enters the molding cavity 230. If it enters, the filling port 4200 is considered to be aligned with the molding cavity 230. Afterwards, the motion parameters of the first motion mechanism 5100 are controlled according to the relative positional relationship between the remaining molding cavities 230 and the first molding cavity 230, so as to realize the alignment of the filling port 4200 with the other molding cavities 230 in sequence. In other implementations, alignment can also be determined by setting up a laser alignment system, optical alignment system or other alignment system in the prior art, and the embodiments of the present invention do not limit this. Since the alignment determination device or method is not an improvement of the present invention, it will not be described in detail here.

[0068] Please continue to refer to this. Figure 3 The multiple molding cavities 230 are arranged in an array. When the mold 200 is placed on the first platform 3100, the multiple molding cavities 230 have multiple rows and multiple columns, where a "row" means that the multiple molding cavities 230 are arranged parallel to the Y-axis, and a "column" means that the multiple molding cavities 230 are arranged parallel to the X-axis. For more details, please refer to the reference. Figure 1 and Figure 2 and combined Figure 4The first motion mechanism 5100 includes a first drive assembly 5110, a second drive assembly 5120, and a third drive assembly 5130. The first drive assembly 5110 is connected to the first platform 3100 and drives the first platform 3100 to perform reciprocating linear motion along the X direction. The second drive assembly 5120 is connected to the third drive assembly 5130, and the infusion assembly 4000 is connected to the third drive assembly 5130. The second drive assembly 5120 drives the third drive assembly 5130 and the infusion assembly 4000 to perform reciprocating linear motion along the Y direction, and the third drive assembly 5130 drives the infusion assembly 4000 to perform reciprocating linear motion along the Z direction.

[0069] In actual operation, the first drive component 5110 can first cause the first platform 3100 to move along the X direction, thereby driving the mold 200 to move synchronously along the X direction, and aligning a row of molding cavities 230 on the mold 200 with the filling port 4200 in the X direction (i.e., the row of molding cavities 230 and the filling port 4200 have the same coordinates on the X-axis). Then, the second drive component 5120 drives the third drive component 5130 and the filling component 4000 to move along the Y direction, so that the filling port 4200 is successively aligned with each of the molding cavities 230 in the Y direction, that is, the filling port 4200 is successively aligned with each of the molding cavities 230 in the row (i.e., the filling port 4200 and the molding cavity 230 it is aligned with have the same coordinates on the XY plane). After each alignment, the filling component 4000 performs the corresponding action to complete the material filling work of the corresponding molding cavity 230. After all the molding cavities 230 in this row have been filled with raw material, the first drive assembly 5110 drives the first platform 3100 to move along the X direction again, so that the mold 200 moves synchronously along the X direction, and aligns the other row of molding cavities 230 with the filling port 4200 in the X direction, thereby allowing the other row of molding cavities 230 to be filled with raw material. Filling all the molding cavities 230 on the mold 200 row by row in this way reduces misalignment. Furthermore, the arrangement of the first motion mechanism 5100 reduces its volume, which helps to reduce the space required for the first sub-cavity 1001. It should be understood that in this embodiment, the second driving component 5120 can first drive the third driving component 5130 and the injection component 4000 to move along the Y direction, so that the injection port 4200 is aligned with a row of molding cavities 230 in the Y direction. Then, the first driving component 5110 drives the first platform 3100 to move along the X direction, and drives the mold 200 to move synchronously along the X direction, so that each of the molding cavities 230 in this row is aligned with the injection port 4200 one by one, that is, the raw material is injected into all the molding cavities 230 one row at a time.

[0070] Please continue to refer to this. Figure 1 and Figure 2Preferably, the housing 1000 further forms a second sub-cavity 1002, which is selectively connected to or isolated from the environment outside the housing 1000. A second mold transfer position 1002a is provided within the second sub-cavity 1002. The vacuum generating system 2000 is also used to evacuate the second sub-cavity 1002. The stage assembly 3000 further includes a second stage 3200, which is used to be disposed in the second sub-cavity 1002, and the second stage 3200 is also provided with multiple mold placement positions, each of which can be used to place one mold 200. The motion mechanism 5000 further includes a second motion mechanism 5200 and a third motion mechanism 5300. The second motion mechanism 5200 is at least partially disposed in the second sub-cavity 1002 and is used to control the movement of the second stage 3200, so that the second stage 3200 enters the second sub-cavity 1002 or at least partially extends out of the housing 1000, and selectively causes one of the mold placement positions on the second stage 3200 to coincide with the second mold junction position 1002a. In this embodiment, the aforementioned "the first sub-cavity 1001 selectively communicates with or is isolated from the environment outside the first sub-cavity" means that the first sub-cavity 1001 selectively communicates with or is isolated from the second sub-cavity 1002. The first sub-cavity 1001 is provided with a first mold junction position 1001a, and the first stage 3100 can move along the X direction to the first mold junction position 1001a. The third motion mechanism 5300 is used to transfer the mold 200 between the mold placement position of the second platform 3200 that coincides with the second mold junction position 1002a and the first platform 3100 located at the first mold junction position 1001a. Figure 1 The second platform 3200 shown has two mold placement positions, and a mold 200 is placed on each of the two mold placement positions. One of the mold placement positions coincides with the second mold junction position 1002a, and the first platform 3100 is located at the first mold placement position 1001.

[0071] Here, "the second stage 3200 enters the first sub-cavity 1001" means that the second stage 3200 is fully inside the second sub-cavity 1002. When "the second stage 3200 extends at least partially out of the housing 1000", at least one of the mold placement positions on the second stage 3200 is located outside the housing 1000.

[0072] The second platform 3200 can have two or more mold placement positions. Taking an example where the second platform 3200 has two mold placement positions, and when the second platform 3200 at least partially extends out of the housing 1000, one mold placement position is located outside the housing 1000, while the other mold placement position remains within the second sub-cavity 1002, the usage process of the infusion system is described. The two mold placement positions are designated as the first mold placement position and the second mold placement position. The usage process includes:

[0073] Step S1, connect the second sub-cavity 1002 to the environment outside the housing 1000.

[0074] In step S2, the second stage 3200 is controlled by the second motion mechanism 5200 to extend at least partially out of the housing 1000, so that the first mold placement position is located outside the housing 1000.

[0075] Step S3: Place one of the molds 200s on the first mold placement position. For ease of description, the mold 200 placed on the first mold placement position will be referred to as the first mold 200a (e.g., ...). Figure 1 (as marked in the text).

[0076] In step S4, the second stage 3200 is moved by the second motion mechanism 5200 so that the second stage 3200 is fully inserted into the second sub-cavity 1002 and the first mold placement position coincides with the second mold junction position 1002a. That is, at this time, the first mold 200a is located on the second mold junction position 1002a.

[0077] Step S5, isolate the second sub-cavity 1002 from the environment outside the housing 1000.

[0078] Step S6: Use the vacuum generating system 2000 to evacuate the first sub-cavity 1001 and the second sub-cavity 1002 until a specified vacuum level is reached. It can be understood that if the first sub-cavity 1001 was already isolated from the second sub-cavity 1002 and at the specified vacuum level before this step, then in this step, only the second sub-cavity 1002 needs to be evacuated to the specified vacuum level. The vacuum level inside the second sub-cavity 1002 is usually the same as the vacuum level inside the first sub-cavity 1001. Furthermore, the vacuum level of the first sub-cavity remains essentially constant during the filling process, and its vacuum level also remains essentially constant when the second sub-cavity 1002 is in a vacuum state.

[0079] Step S7: Connect the first sub-cavity 1001 to the second sub-cavity 1002.

[0080] Step S8: The first mold 200a, which is located at the second mold transfer position 1002a, is transferred to the first sub-cavity 1001 by the third motion mechanism 5300 and placed on the first platform 3100 located at the first mold transfer position 1001a.

[0081] In step S9, the third motion mechanism 5300 is completely retracted into the second sub-cavity 1002, thus isolating the first sub-cavity 1001 from the second sub-cavity 1002.

[0082] Step S10: Within the first sub-cavity 1001, the first motion component 5100 controls the first stage 3100 to move the first mold 200a and the injection component 4000, and the injection component 4000 injects raw material into the first mold 200a. After the first mold 200a completes the injection of raw material, the first drive component 5110 drives the first stage 310 to move the first mold 200a along the X direction and return to the first mold transfer position 1001a.

[0083] Step S11, connect the second sub-cavity 1002 to the environment outside the housing 1000.

[0084] In step S12, the second stage 3200 is controlled by the second motion mechanism 5200 to extend at least partially out of the housing 1000, so that the second mold placement position is located outside the housing 1000.

[0085] Step S13: Place another mold 200 on the second mold placement position. Hereinafter, the mold 200 placed on the second mold placement position will be referred to as the second mold 200b.

[0086] In step S14, the second stage 3200 is fully entered into the second sub-cavity 1002 by the second motion mechanism 5200, so that the second mold 200b enters the second sub-cavity 1002, while the first mold placement position still coincides with the second mold junction position 1002a.

[0087] Step S15: Isolate the second sub-cavity 1002 from the environment outside the housing 1000, and use the vacuum generating system 2000 to evacuate the second sub-cavity 1002 to a specified vacuum level.

[0088] Step S16: Connect the first sub-cavity 1001 to the second sub-cavity 1002.

[0089] Step S17: The first mold 200a, which has been filled with raw materials and is already on the first mold transfer position 1001a, is transferred to the first mold placement position by the third motion mechanism 5300.

[0090] Step S18: The second stage 3200 is controlled to move by the second motion mechanism 5200 so that the second mold placement position coincides with the second mold junction position 1002a.

[0091] Step S19: The second mold 200b is transferred to the first platform 3100, which is still located at the first mold transfer position 1001a, by the third motion mechanism 5300.

[0092] In step S20, the third motion mechanism 5300 is completely retracted into the second sub-cavity 1002, thereby isolating the first sub-cavity 1001 from the second sub-cavity 1002.

[0093] Step S21: The second mold 200b is filled with raw material in the second sub-cavity 1002, and after filling is completed, the first platform 3100 is returned to the first mold transfer position 1001a.

[0094] Step S22, connect the second sub-cavity 1002 to the environment outside the housing 1000.

[0095] Step S23: The second stage 3200 is moved by the second motion mechanism 5200 so that the first mold placement position is located outside the housing 1000.

[0096] Step S24: Unload the first mold 200a, which has been vacuum-filled, from the first mold placement position.

[0097] Step S25: Place another unvacuum-filled first mold 200a on the first mold placement position.

[0098] Step S26: The second stage 3200 is controlled to move by the second motion mechanism 5200 so that the first mold placement position is fully entered into the second sub-cavity 1002. At this time, the second mold placement position still coincides with the second mold junction position 1002a.

[0099] Step S27: Isolate the second sub-cavity 1002 from the environment outside the housing 1000, and evacuate the second sub-cavity 1002 to a specified vacuum level.

[0100] Step S28: Connect the first sub-cavity 1001 to the second sub-cavity 1002.

[0101] Step S29: The second mold 200b, which has been filled with raw materials, is transferred to the second sub-cavity 1002 and placed in the second mold placement position by the third motion mechanism 5300.

[0102] In step S30, the second stage 3200 is moved by the second motion mechanism 5200 so that the first mold placement position coincides with the second mold junction position 1002a.

[0103] Step S31: The third motion mechanism 5300 transfers another first mold 200a, which is in the first mold placement position, to the first platform 3200.

[0104] In step S32, the third motion mechanism 5300 is completely retracted into the second sub-cavity 1002, thereby isolating the first sub-cavity 1001 from the second sub-cavity 1002.

[0105] Step S33: In the first sub-cavity 1001, the other first mold 200a is filled with raw material, and after the other first mold 200a is filled with raw material, the first platform 3100 is returned to the first mold transfer position 1001a.

[0106] Step S34, connect the second sub-cavity 1002 to the environment outside the housing 1000.

[0107] Step S35: The second stage 3200 is moved by the second motion mechanism 5200 so that the second mold placement position is located outside the housing 1000.

[0108] Step S36: Unload the second mold 200b that has been vacuum-filled.

[0109] Step S37: Place another unvacuum-filled second mold 200b at the second mold placement position.

[0110] In step S38, the second stage 3200 is fully entered into the second sub-cavity 1002 by the second motion mechanism 5200, so that the second mold 200b enters the second sub-cavity 1002, while the first mold placement position still coincides with the second mold junction position 1002a.

[0111] Step S39: Isolate the second sub-cavity 1002 from the environment outside the housing 1000, and use the vacuum generating system 2000 to evacuate the second sub-cavity 1002 to a specified vacuum level.

[0112] Then, steps S16 to S39 are repeated to continuously inject raw materials into the plurality of molds 200.

[0113] In the above process, steps S11 to S15 are executed during the execution of step S10, steps S22 to S27 are executed during the execution of step S21, and steps S34 to S39 are executed during the execution of step S33.

[0114] As can be seen from the above usage process, during the process of filling a mold 200 with raw materials in the first sub-cavity 1001, a mold 200 that has already been filled with raw materials can be unloaded, and a mold 200 that has not yet been filled with raw materials can be loaded. That is to say, the filling process and the loading process are executed simultaneously, as are the filling process and the unloading process, and there is no need to repeatedly evacuate the first sub-cavity 1001. This can improve the production cycle of the entire production process and further improve production efficiency.

[0115] Next, the structure of each component of the infusion system will be further described. It should be understood that the following description only represents optional structures for each component, not mandatory constructions, and therefore should not be construed as unduly limiting the present invention.

[0116] Please continue to refer to this. Figure 1 and Figure 2 The housing 1000 includes an outer shell 1100 and a partition plate 1200. The outer shell 1100 forms an inner cavity, and the partition plate 1200 is disposed in the inner cavity, dividing the inner cavity into a first sub-cavity 1001 and a second sub-cavity 1002. The partition plate 1100 has a first window (not shown in the figure) communicating with the first sub-cavity 1001 and the second sub-cavity 1002, and the outer shell 1100 has a second window (not shown in the figure) communicating with the second sub-cavity 1200.

[0117] In this embodiment, both the partition plate 1200 and the first window are parallel to the XZ plane, that is, the first sub-cavity 1001 and the second sub-cavity 1002 are arranged along the Y direction. Furthermore, the second window can also be parallel to the XZ plane.

[0118] The infusion system also includes a sealing component (not shown in the figure), the sealing component including a first sealing component 6100 (e.g. Figures 5 to 7(As indicated) and the second sealing component 6200. The first sealing component 6100 is used to selectively close or release the first window. It should be understood that when the first sealing component 6100 closes the first window, the first sub-cavity 1001 and the second sub-cavity 1002 are isolated to form a sealed chamber. When the first sealing component 6100 releases the first window, the first sub-cavity 1001 and the second sub-cavity 1002 are interconnected, allowing the third motion mechanism 5300 to control the mold 200 to pass through the first window to transfer between the mold placement position of the second platform 3200 that coincides with the second mold intersection position 1002a and the first platform 3100 located at the first mold intersection position 1001a. The second sealing component 6200 selectively closes or releases the second window. When the second sealing component 6200 closes the second window, the second sub-cavity 1002 is isolated from the environment outside the housing 1000. When the second sealing component 6200 releases the closure of the second window, the second sub-cavity 1002 communicates with the environment outside the housing 1000, allowing the second stage 3200 to at least partially pass through the second window to extend out of the housing 1000 or fully enter the second sub-cavity.

[0119] Figure 5 A schematic diagram of the structure of a first enclosure component 6100 provided in one embodiment is shown. Figure 5 As shown, the first sealing assembly 6100 includes a first sealing door 6110 and a sixth driving part 6120, the sixth driving part 6120 being connected to the housing 1000. The sixth driving part 6120 is also connected to the first sealing door 6110 and is used to drive the first sealing door 6110 to reciprocate linearly in a direction parallel to the first window, so as to cover or deviate from the first window. It should be understood that the first sealing assembly 6100 also includes a sealing ring (not shown in the figure). When the first sealing assembly 6100 closes the first window, the sealing ring surrounds the first window and is clamped between the partition plate 1200 and the first sealing door 6110 to ensure a sealing effect. The "direction parallel to the first window" can be the first direction (i.e., the X direction) or the third direction (i.e., the Z direction). The following description will use the third direction, i.e., the Z direction, as an example of the "direction parallel to the first window".

[0120] When the distance between the first sealing door 6110 and the partition plate 1200 is extremely small, the first sealing door 6110 moves in the Z direction. When the first sealing door 6110 contacts the sealing ring, the portion of the sealing ring in contact with the first sealing door 6110 is compressed. However, this causes significant wear to the sealing ring, which is detrimental to long-term use. Therefore, the first sealing assembly 6100 further includes a seventh driving unit 6130, which is connected to the first sealing door 6110 and used to drive the first sealing door 6110 to reciprocate in a direction perpendicular to the first window, moving it closer to or away from the partition plate 1200. In this embodiment, the "direction perpendicular to the first window" is the second direction, i.e., the Y direction.

[0121] For details, please continue to refer to Figure 5 The first sealing assembly 6100 further includes a second guide portion 6140, a second engaging portion 6150, and a third guide portion 6160. The second guide portion 6140 is connected to the housing 1000 and extends along the Z direction. The second engaging portion 6150 is connected to the second guide portion 6140 and can move along the Z direction under the constraint of the second guide portion 6140. One end of the third guide portion 6160 is connected to the first sealing door 6110, and the other end is connected to the second engaging portion 6150. The third guide portion 6160 extends along the Y direction and can move along the Y direction on the second engaging portion 6150. The sixth drive portion 6120 is connected to the second engaging portion 6150 to drive the second engaging portion 6150 to reciprocate linearly along the Z direction, thereby driving the first sealing door 6110 to reciprocate linearly. The seventh drive portion 6130 is disposed on the second engaging portion 6150 and connected to the first sealing door 6110.

[0122] More specifically, the first enclosure assembly 6100 preferably includes a door frame structure, through which the sixth drive unit 6120 is connected to the housing 1000. The door frame structure specifically includes a first connecting plate 6171, a connecting seat 6172, a second connecting plate 6173, a floating head 6174, and a third connecting plate 6175. Optionally, the first connecting plate 6171 is connected to the housing 1000. The connecting seat 6172 is connected to the first connecting plate 6171. Two second connecting plates 6173 are connected to opposite ends of the first connecting plate 6171 in the X direction, and each second connecting plate 6173 extends into the first sub-cavity 1001. Alternatively, the second connecting portion 6173 extends into the second sub-cavity 1002. The third connecting plate 6175 is located within the inner cavity of the housing 1000 and is connected to the second joint portion 6150. The floating head 6174 is disposed on the third connecting plate 6175. There are two second guide portions 6140, each disposed on one of the two second connecting plates 6173 (i.e., the second guide portions 6140 are connected to the housing 1000 via the door frame structure), and each second guide portion 6140 can be a guide rail. The second joining portion 6150 has a U-shaped structure and includes two opposing joining plates 6151. In this embodiment, the two joining plates 6151 are arranged opposite each other in the X direction and are slidably connected to one of the second guide portions 6140. The first sealing door 6110 is simultaneously connected to both joining plates 6151. The sixth drive unit 6120 includes a cylinder, referred to as the first cylinder. The cylinder body of the first cylinder is disposed outside the housing 1000 and connected to the connecting seat 6172. The piston rod of the first cylinder extends in the negative Z direction and passes through the connecting seat 6172, the first connecting plate 6171, and the top wall of the housing 1000 in sequence before connecting to the floating head 6174. By setting the floating head 6174, assembly errors caused by machining errors between various components can be avoided. The extension and retraction movement of the piston rod of the first cylinder drives the second engaging part 6150 to reciprocate linearly in the Z direction under the constraint of the two second guide parts 6140, thereby driving the first sealing door 6110 to reciprocate linearly in the Z direction to cover or deviate from the first window. Here, "covering" means that on a plane perpendicular to the Y direction (i.e., the XZ plane), the projection of the first window is completely located inside the projection of the first sealing door 6110. Furthermore, when the first sealing door 6110 is deviated from the first window, the projection of the first window is at least partially located outside the projection of the first sealing door 6110 on a plane perpendicular to the Y direction.

[0123] Furthermore, each of the connecting plates 6151 is provided with a through hole (not shown in the figure), and each through hole is provided with a bearing seat 6181. The bearing seats 6181 on the two second connecting plates 6151 are symmetrically arranged. The third guide part 6160 can be a guide shaft, and there are at least two third guide parts 6160, which are respectively connected to the two sides of the first sealing door 6110 in the X direction. Each third guide seat 6160 also passes through the through hole on the connecting plate 6151 and is connected to the corresponding bearing seat 6181. The third guide part 6160 can reciprocate linearly in the Y direction under the constraint of the bearing seat 6181. In addition, the first sealing door 6110 is provided with a lead screw nut 6182. The seventh drive part 6130 includes a motor and a lead screw provided at the output end of the motor. The motor of the seventh drive part 6130 can be referred to as the first motor 6131, and its lead screw is referred to as the first lead screw 6132. The first lead screw 6132 extends in the Y direction. The first motor 6131 is connected to the second joint 6150, and the first lead screw 6132 passes through the second joint 6150 and is threadedly engaged with the lead screw nut 6182 for helical transmission. When the first motor 6131 rotates in a first predetermined direction, such as clockwise, the first sealing door 6110 can move away from the partition plate 1200. Conversely, when the first motor 6131 rotates in the opposite direction, i.e., counterclockwise, the first sealing door 6110 moves closer to the partition plate 1200. There are two first motors 6131, and the two first motors 6131 are respectively disposed on the two second joints 6150.

[0124] In other words, when the first window is not closed, the first closing assembly 6100 can be controlled to close the first window by the following operation: the second joint 6150 is pushed by the first cylinder to move in the negative Z direction, thereby driving the first sealing door 6110 to move in the negative Z direction, and causing the first sealing door 6110 to cover the first window. The first motor 6131 and the first lead screw 6132 drive the first sealing door 6110 to move in a direction close to the partition plate 1200 (if the first sealing door 6110 is located in the first sub-cavity 1100, then the direction close to the partition plate 1200 is the positive Y direction; if the first sealing door 6110 is located in the second sub-cavity 1200, then the direction close to the partition plate 1200 is the negative Y direction), so that the first sealing door 6110 and the partition plate 1200 clamp the sealing ring. The movement of the first sealing door 6110 in the Z direction and the movement in the Y direction can be performed simultaneously, or the movement in the Z direction can be performed first, followed by the movement in the Y direction.

[0125] It is understood that the reverse operation can release the first sealing assembly 6100 from the first window. Specifically, the first motor 6131 and the first lead screw 6132 drive the first sealing door 6110 to move away from the partition plate 1200, thereby releasing the clamping force applied to the sealing ring. Furthermore, the first cylinder pulls the second engaging portion 6150 to move in the positive Z direction, thereby causing the first sealing door 6110 to move in the positive Z direction and completely deviate from the first window. Similarly, the movement of the first sealing door 6110 in both directions can be performed simultaneously, or the movement in the Y direction can be performed first, followed by the movement in the Z direction.

[0126] In an alternative implementation, please refer to Figure 6 and Figure 7 The sixth drive unit 6120 includes a motor and a lead screw connected to the output end of the motor. The motor is referred to as the second motor 6121, and the lead screw as the second lead screw 6122, which extends along the Z direction. The second motor 6121 is mounted on a second connecting plate 6173, and the second lead screw 6122 extends along the Z direction. The connecting plate 6151 near the second motor 6121 may include a protrusion 6152, on which a first threaded connection portion (not shown) is provided. The first threaded connection portion is, for example, a threaded through hole or a lead screw nut. The protrusion 6152 is sleeved on the second lead screw 6122 through the first threaded connection portion and threadedly engages with the second lead screw 6122 for helical transmission. It is understood that in this implementation, the second guide portion may not be provided on the second connecting plate 6173 where the second motor 6122 is located (that is, the number of second guide portions 6140 is one, and the second guide portion 6140 and the second motor are located on different second connecting portions 6173). Alternatively, in another alternative implementation, the sixth driving unit may be a slide cylinder, the cylinder body of which is provided on a second connecting plate, and the slide of which is connected to a second joint portion (not shown in the figure). It is understood that in both of these alternative implementations, it is not necessary to provide the connecting seat, the floating head, and the third connecting plate; that is, the connecting seat, the floating head, and the third connecting plate are not essential structures.

[0127] Please return to the reference. Figure 1The second sealing assembly 6200 includes an eighth drive unit 6210 and a second sealing door 6220. The eighth drive unit 6210 is disposed on the housing 1100 and connected to the second sealing door 6220. The eighth drive unit 6210 is used to drive the second sealing door 6220 to reciprocate in a direction perpendicular to the second window, so as to move closer to or away from the housing 1100. The eighth drive unit 6210 is also used to drive the second sealing door 6220 to reciprocate around a second axis, so as to cover or deviate from the second window. The second axis extends in a direction perpendicular to the second window. In this embodiment, the "direction perpendicular to the second window" refers to the second direction, i.e., the Y direction. And, the meaning of the second sealing door 6220 "covering" the second window is that, on the plane perpendicular to the second axis (i.e., the XZ plane), the projection of the second window is completely located inside the projection of the second sealing door 6220. When the second sealing door 6220 is "offset" from the second window, the projection of the second window on the XZ plane is at least partially located outside the projection of the second sealing door 6220. Preferably, the eighth drive unit 6210 is a rotary clamping cylinder. Furthermore, the second sealing assembly 6200 also includes a sealing ring that surrounds the second window and is clamped between the housing 1100 and the second sealing door 6220 when the second sealing assembly 6200 closes the second window.

[0128] The present invention does not impose any special limitations on the structure of the first motion mechanism 5100. Figure 4 An optional structure is shown. Please refer to [reference needed]. Figure 4The first drive assembly 5110 includes a first drive unit, which may include a motor and a lead screw connected to the output end of the motor. The motor of the first drive unit may be referred to as a third motor 5111, and the lead screw may be referred to as a third lead screw 5112. The third lead screw 5112 extends along the X direction. A second threaded connection part (not shown in the figure) may be provided on the first platform 3100. The second threaded connection part is a threaded through hole or a lead screw nut. The third motor 5111 is connected to the cavity wall of the first sub-cavity 1001. The third lead screw 5112 passes through the first threaded connection part of the first platform 3100 and is threadedly engaged with the second threaded connection part to perform helical transmission. That is, the first platform 3100 can be controlled to perform reciprocating linear motion along the X direction by the forward and reverse rotation of the third motor 5111. The second drive assembly 5120 includes a second drive unit, which may include a motor and a lead screw connected to the output end of the motor. The motor of the second drive unit may be referred to as a fourth motor 5121, and the lead screw may be referred to as a fourth lead screw 5122. The fourth motor 5121 is connected to the cavity wall of the first sub-cavity 1001, and the fourth lead screw 5122 extends along the Y direction. The third drive assembly 5130 includes a third drive unit and a first connecting member 5131. The third drive unit includes a motor and a lead screw connected to the output end of the motor. The motor of the third drive unit is referred to as the fifth motor 5132, and the lead screw is referred to as the fifth lead screw 5133. The first connecting member 5131 is provided with a third threaded connection part (not shown in the figure), such as a threaded connection hole or a lead screw nut. The connecting member 5131 is sleeved on the fourth lead screw 5212 through the third threaded connection part and threadedly engaged with the fourth lead screw 5212 for helical transmission. The fifth motor 5132 is connected to the first connecting member 5131, and the fifth lead screw 5133 extends along the Z direction. The filling assembly 4000 further includes a second connector 4300, which is connected to the raw material container 4100. A fourth threaded connection portion may be provided on the second connector 4300. The second connector 4300 is sleeved on the fifth lead screw 5133 through the fourth threaded connection portion and is threadedly engaged with the fifth lead screw 5133 to perform helical transmission.

[0129] Please return to the reference. Figure 1 and Figure 2 and combined Figure 8The plurality of mold placement positions located on the second platform 3200 are arranged symmetrically at their centers. The second motion mechanism 5200 is used to drive the second platform 3200 to reciprocate linearly along a fourth direction, so that the second platform 3200 enters the second sub-cavity 1002 or at least partially extends out of the housing 1000, and to control the second platform 3200 to rotate about a first axis to selectively make one of the mold placement positions coincide with the second mold junction position 1002a (i.e., one of the mold placement positions and the second mold junction position 1002a have the same coordinates in the XY plane). The first axis passes through the center of symmetry of the plurality of mold placement positions and extends along the Z direction. The fourth direction is perpendicular to the Z direction. In this embodiment, the fourth direction is parallel to the second direction, that is, the fourth direction is also the Y direction. In this document, the positive direction of the Y-axis is taken as the positive direction of the fourth direction. It should be understood that when the second motion mechanism 5200 drives the second platform 3200 to reciprocate linearly along the Y direction so that the second platform 3200 enters the second sub-cavity 1002 or at least partially extends out of the housing 1000, the second platform 3200 needs to be aligned with the second window in the X direction. Furthermore, the amount of movement of the second platform 3200 in the Y direction and the amount of rotation about the first axis controlled by the second motion mechanism 5200 can be set as needed, as long as one of the mold placement positions on the second platform 3200 coincides with the second mold junction position 1002a.

[0130] Optionally, the second motion mechanism 5200 includes a fourth drive assembly 5210, a first engagement portion 5220, and a fifth drive portion 5230. The first engagement portion 5220 is disposed within the second sub-cavity 1002. The fourth drive assembly 5210 is connected to the first engagement portion 5220 and is used to drive the first engagement portion 5220 to perform reciprocating linear motion along the extension direction of the Y-axis. The fifth drive portion 5230 is disposed on the first engagement portion 5220 and connected to the second platform 3200 to drive the second platform 3200 to rotate around the first axis. The fifth drive portion 5230 may include a motor, referred to as a sixth motor, and the second platform 3200 may be directly connected to the output end of the sixth motor. The first engagement portion 5220 may be a plate-like structure.

[0131] For a more detailed structure of the fourth drive component 5210, please refer to [the relevant documentation]. Figure 8 .like Figure 8As shown, the fourth drive assembly 5210 includes a first guide portion 5211, a fourth drive portion 5212, and a transmission portion 5213. The first guide portion 5211 is disposed on the cavity wall, such as the bottom wall, of the second sub-cavity 1002 and extends along the Y direction. The first engagement portion 5220 is disposed on the first guide portion 5220 and reciprocates linearly along the Y direction under the constraint of the first guide portion 5220. The fourth drive portion 5212 may include a cylinder, which may be referred to as a second cylinder. The cylinder body of the second cylinder may be disposed on the housing 1100 and located outside the housing 1000. The piston rod of the second cylinder extends along a fifth direction and passes through the housing 1100 to reach the second sub-cavity 1002. The fifth direction is perpendicular to the fourth direction and the third direction. In this embodiment, the fifth direction is, for example, parallel to the first direction, that is, the fifth direction is the X direction. In this document, the positive direction of the X-axis is taken as the positive direction of the fifth direction. The transmission unit 5213 includes a rack 5213a, a gear 5213b, and a connecting rod unit. The rack 5213a can be connected to the piston rod of the second cylinder in any suitable manner. The gear 5213b is rotatably connected to the housing 1000 and meshes with the rack 5212a. The gear 5213b is connected to the first engagement portion 5220 via the connecting rod unit. Specifically, the connecting rod unit includes a first connecting rod 5213c and a second connecting rod 5213d. The gear 5213b is fixedly connected to the first connecting rod 5213c, the first connecting rod 5213c is rotatably connected to the second connecting rod 5213d, and the second connecting rod 5213d is rotatably connected to the second engagement portion 5220.

[0132] by Figure 1 , Figure 2 and Figure 8 Taking the orientation shown as an example, when the piston rod of the second cylinder extends, the rack 5212a moves along the positive direction of the X-axis to drive the gear 5212b to rotate clockwise, thereby driving the second engagement portion 5220 to move along the positive direction of the Y-axis through the connecting rod unit. This allows the second platform 3200 to extend at least partially out of the housing 1000. Conversely, when the piston rod of the second cylinder retracts, the rack 5212a moves along the negative direction of the X-axis to pull the gear 5212b to rotate counterclockwise, thereby pulling the second engagement portion 5220 to move along the negative direction of the Y-axis through the connecting rod unit, and causing the second platform 3200 to fully enter the second sub-cavity 1002. Preferably, the fourth drive assembly 5210 may further include a sixth guide portion 5214 extending along the X-direction, on which the rack 5213a is slidably disposed to improve the smoothness of the rack 5213a's movement.

[0133] In this embodiment of the invention, when two mold placement positions are provided on the second platform 3200, the two second platforms 3200 are preferably elongated structures extending along the Y direction. The two mold placement positions are respectively located at both ends of the second platform 3200 in the Y direction. In addition, the second mold junction position 1002a is also aligned with the second window in the X direction. Thus, each time the fifth driving unit 5230 drives the second platform 3200 to rotate 180°, the two mold placement positions can alternately coincide with the second mold junction position 1002a, wherein the mold placement position farther away from the second window coincides with the second mold junction position 1002a. Furthermore, in order to reduce the space of the second sub-cavity 1002, it is preferable that the fifth drive unit 5230 drives the second stage 3200 to rotate back and forth (that is, first rotate 180° in a second predetermined direction, for example, clockwise, so that one of the mold placement positions coincides with the second mold intersection position 1002a, and then rotate 180° in the opposite direction, i.e., counterclockwise, so that the other mold placement position coincides with the second mold intersection position 1002a).

[0134] In order to ensure that the second stage 3200 moves in the negative Y direction to fully enter the second sub-cavity 1002, one of the mold placement positions coincides with the second mold junction position 1002a, such as... Figure 2 and Figure 8 As shown, the injection system further includes a limiting part 7000. The limiting part 7000 is used to limit the end position of the first joint 5220 when it moves in the negative direction of the Y-axis, so that when the first joint 5220 moves to the end position in the negative direction of the Y-axis, the mold placement position on the second stage 3200 away from the second window coincides with the second mold junction position 1002a.

[0135] The limiting portion 7000 includes a first limiting member 7100 and a second limiting member 7200. The first limiting member 7100 is disposed on the first joint portion 5220 and can be a block structure. The second limiting portion 7200 is disposed on the housing 1000 and located within the second sub-cavity 1002. The second limiting member 7200 is used to abut against the first limiting member 7100. When the second limiting member 7200 abuts against the first limiting member 7100, it prevents the first joint portion 5220 from moving in the negative direction of the Y-axis. That is, when the second limiting member 7200 abuts against the first limiting member 7100, the first joint portion 5220 moves to its end position in the negative direction of the Y-axis, and at this time, the mold placement position on the second platform 3200 away from the second window coincides with the second mold junction position 1002a.

[0136] Furthermore, please refer to the following: Figure 8 The second limiting member 7200 includes a limiting seat 7210 and a limiting rod 7220. The limiting seat 7210 is disposed on the housing 1000, and the limiting rod 7220 extends along the Y-axis and is disposed on the limiting seat 7210. It is configured to reciprocate linearly along the Y-direction to adjust the distance from the end of the limiting rod 7220 near the first limiting member 7100 to the limiting seat 7210. The end of the limiting rod 7220 near the first limiting member 7100 is used to abut against the first limiting member 7100. In other words, by moving the limiting rod 7220 along the Y-direction, the endpoint position of the first engagement portion 5220 when moving in the negative Y-direction can be adjusted, improving the flexibility of use. The limiting rod 7220 is preferably a bolt, which is threadedly connected to the limiting member 7210.

[0137] Please return to the reference. Figure 2 The third motion mechanism 5300 includes a conveying component 5310 and a gripping component 5320, with the gripping component 5320 connected to the conveying component 5310. The conveying component 5310 is used to drive the gripping component 5320 to move between the first sub-cavity 1001 and the second sub-cavity 1002, so that the gripping component 5320 can pick up and place the mold 200 at the first mold transfer position 1001a and at the second mold transfer position 1002a, thereby realizing the transfer of the mold 200 between the mold pick-up and place position of the second platform 3200 that coincides with the second mold transfer position 1002a and the first platform 3100 located at the first mold transfer position 1001a.

[0138] For details, please continue to refer to Figure 2 The conveying assembly 5310 includes a third joint 5311 and an eleventh drive unit 5312. The third joint 5311 may be a plate-like structure, and the gripping assembly 5320 is connected to the third joint 5311. The eleventh drive unit 5312 may include a motor, referred to as the seventh motor, which is disposed on the housing 1000 and located in the inner cavity of the housing 1000. Figure 2The diagram shows the seventh motor located within the second sub-cavity 1002 and connected to the bottom wall of the second sub-cavity 1002. The output end of the seventh motor is connected to the third joint 5311 and is used to drive the third joint 5311 to rotate about a third axis. This allows a portion of the third joint 5311 and the gripping assembly 5320 connected to the third joint 5311 to pass through the first window via rotational movement, thereby achieving the purpose of transferring the gripping assembly 5320 between the first sub-cavity 1001 and the second sub-cavity 1002. The third axis extends along the third direction, i.e., the Z direction. Furthermore, to reduce the size of the inner cavity of the housing 1000, it is preferable that the seventh motor drives the third joint 5311 to reciprocate around the third axis. Specifically, the seventh motor drives the third joint 5311 to rotate around a predetermined direction, for example, clockwise, by a predetermined angle, so that the gripping component 5320 is transferred from the second sub-cavity 1002 to the first sub-cavity 1001. Additionally, the seventh motor drives the third joint 5311 to rotate in the opposite direction, i.e., counterclockwise, by the predetermined angle, so that the gripping component 5311 returns from the first sub-cavity 1001 to the second sub-cavity 1002. It should be understood that the seventh motor stops operating when the conveying component 5220 moves the gripping component 5230 above the first mold junction position 1001a of the first sub-cavity 1001, and stops operating when the conveying component 5220 moves the gripping component 5230 to the second mold junction position 1002a of the second sub-cavity 1002.

[0139] Figure 9 and Figure 10 The structure of the gripping component 5320 is shown. For example... Figure 9 and Figure 10As shown, the gripping component 5320 includes a movable plate 5321, a ninth drive unit 5322, a tenth drive unit 5323, and a clamping unit 5324. The ninth drive unit 5322 is connected to the conveying component 5310, specifically to the third engagement portion 5311 of the conveying component 5310. The ninth drive unit 5322 is also connected to the movable plate 5321 to drive the movable plate 5321 to perform reciprocating linear motion along the Z direction. The tenth driving part 5323 is connected to the movable plate 5321, and the clamping part 5324 is connected to the tenth driving part 5323, and includes a first gripper 5324a and a second gripper 5324b disposed opposite to each other. Under the drive of the tenth driving part 5323, the first gripper 5324a and the second gripper 5324b reciprocate linearly in a direction parallel to the movable plate 5321, so that the first gripper 5324a and the second gripper 5324b move closer to each other to grasp the mold 200 or move further apart to release the mold 200.

[0140] Optionally, the gripping component 5320 further includes a fourth guide portion 5325, which is connected to the third engaging portion 5311 of the conveying component 5310 and extends in the negative direction of the Z direction. The movable plate 5321 is movably connected to the fourth guide portion 5325. The ninth drive unit 5322 includes a motor and a lead screw connected to the output end of the motor. The motor may be referred to as the eighth motor 5322a, and the lead screw may be referred to as the sixth lead screw 5322b, which extends in the Z direction. The movable plate 5321 is sleeved on the sixth lead screw 5322b and threadedly engaged with the sixth lead screw 5322b for helical transmission. Under the combined action of the sixth lead screw 5322b and the fourth guide portion 5325, the movable plate 5321 can reciprocate linearly in the Z direction without rotating with the sixth lead screw 5322b.

[0141] The movable plate 5321 is provided with a fixing part 5327. The tenth drive part 5323 includes a motor and a lead screw connected to the output end of the motor. The motor can be referred to as the ninth motor 5323a, and the lead screw is referred to as the seventh lead screw. The seventh lead screw extends in a direction parallel to the movable plate 5321, and the end of the seventh lead screw away from the ninth motor 5323a can be connected to the fixing part 5327 through a bearing. The seventh lead screw includes an axially connected first segment 5323b and a second segment 5323c. The external thread on the first segment 5323b has the opposite rotation direction to the external thread on the second segment 5323c. The gripping assembly 5320 also includes a fifth guide part 5326, which is disposed on the movable plate 5321 and arranged parallel to the seventh lead screw. The clamping part 5324 further includes a first connecting block 5324c and a second connecting block 5324d. The first connecting block 5324c and the second connecting block 5324d are slidably connected to the fifth guide part 5326, allowing them to move along the fifth guide part 5326. The first connecting block 5324c is also provided with a fifth threaded connection part (not shown in the figure). The fifth threaded connection part can be a threaded through hole or a lead screw nut. The first connecting block 5324c is connected to the first segment 5323b through the fifth threaded connection part and is threadedly engaged with the first segment 5323b for helical transmission. The second connecting block 5324d is also provided with a sixth threaded connection part (not shown in the figure). The sixth threaded connection part can be a threaded through hole or a lead screw nut. The second connecting block 5324d is connected to the second segment 5323c through the sixth thread and is threadedly engaged with the second segment 5323c for helical transmission. The first gripper 5324a is connected to the first connecting block 5324c, and the second gripper 5324b is connected to the second connecting block 5324d. It can be understood that the first segment 5323b and the second segment 5323c can be formed separately and then connected by the coupling 5323d for ease of installation and adjustment. Alternatively, the first segment 5323b and the second segment 5323c can also be formed as a single piece.

[0142] In addition, please return to the reference. Figure 3The mold 200 is provided with positioning holes 240. The gripping assembly 5230 also includes a positioning shaft 5328, which is connected to the movable plate 5321 and extends along the Z direction. The positioning shaft 5328 is used to insert into the positioning holes 240 on the mold 200, so as to fix the position of the mold 200 by means of the positioning shaft 5328, and prevent the mold 200 from shifting or moving during the opposite movement (i.e., moving in the direction of mutual approach) of the first gripper 5324a and the second gripper 5324b, which would make it difficult for the first gripper 5324a and the second gripper 5324b to grip the mold 200. Optionally, there are two or more positioning holes 240, and preferably two or more positioning holes 240 are arranged centrally symmetrically on the mold 200. The number and arrangement of the positioning shafts 5328 are adapted to the number and arrangement of the positioning holes 240.

[0143] The process of transferring the mold 200 located on the mold placement position coinciding with the second mold junction position 1002a on the second platform 3200 to the first platform 3100 located on the first mold junction position 1001a using the third motion mechanism 5300 is specifically as follows:

[0144] First, the eighth motor 5322a drives the sixth lead screw 5322b to rotate in a fourth predetermined direction, for example, clockwise, so that the movable plate 5321 moves (i.e., moves downward) a predetermined distance in the negative direction of the Z-axis, the predetermined distance being preset. At this time, the positioning shaft 5328 is inserted into the positioning hole 240 of the mold 200 and presses the mold 200 against the second platform 3200 to prevent the mold 200 from shifting or moving. Then, the ninth motor 5323a drives the seventh lead screw to rotate in a fifth predetermined direction, for example, clockwise, thereby driving the first connecting block 5324c and the second connecting block 5324d to move towards each other, so as to drive the first gripper 5324a and the second gripper 5324b to move towards each other and clamp the mold 200. Next, the eighth motor 5322a rotates in the opposite direction (i.e., counterclockwise) to drive the movable plate 5321 to move the predetermined distance along the positive Z-axis. At this time, the clamping part 5324 and the mold 200 move together with the movable plate 5321 along the positive Z-axis (i.e., upward) for the predetermined distance. Subsequently, the seventh motor drives the third connecting part 5311 to rotate clockwise, and carries the gripping assembly 5320 through the first window, into the first sub-cavity 1002, and arrives above the first mold junction position 1001a. At this time, the first platform 3100 has been pre-moved to the first mold junction position 1001a. Next, the eighth motor 5222a drives the sixth lead screw 5322b to rotate clockwise, so that the movable plate 5321 moves a distance along the negative Z-axis until the mold 200 contacts the first platform 3100. Then, the ninth motor 5323a drives the seventh lead screw to rotate counterclockwise, causing the first connecting block 5324c and the second connecting block 5324d to move away from each other, thereby releasing the mold 200. Next, the eighth motor 5323a drives the sixth lead screw 5322b to rotate counterclockwise, causing the movable plate 5321 to move in the positive direction of the Z-axis, thereby disengaging the positioning shaft 5328 from the positioning hole 240 on the mold 200.

[0145] The process of transferring the mold 200 from the first platform 3100 located at the first mold transfer position 1001a to the mold placement position of the second platform 3200 that coincides with the second mold transfer position 1002a using the third motion mechanism 5300 is basically the same and will not be described in detail here.

[0146] It should also be noted that the infusion system may include a controller 8000 (e.g., Figure 1As shown in the diagram, the controller presets the operating parameters of the motion mechanism 5000, the sealing component, the vacuum generating system 2000, and the filling component 4000. In other words, the entire vacuum filling production process can be controlled by the controller, making the filling process intelligent and reducing errors or mistakes caused by manual operation. Furthermore, the filling system may also include a display 9000 (e.g., ...). Figure 1 As shown, the display 9000 is communicatively connected to the controller 8000, each drive unit, and the filling assembly 4000 to display the set operating parameters and actual operating parameters of the entire vacuum filling process, so that the user can monitor the filling process and intervene in a timely manner when the filling system malfunctions.

[0147] Furthermore, the vacuum generating system 2000 includes a vacuum pump 2100, a vacuum valve 2200, and a vacuum gauge 2300. The vacuum pump 2000 has two vacuum pipes, which are respectively connected to the first sub-cavity 1001 and the second sub-cavity 1002. Two vacuum valves 2200 are respectively installed on the two vacuum pipes to control the connection between the first sub-cavity 1001 and the vacuum pump 2100, and between the second sub-cavity 1002 and the vacuum pump 2100, allowing the vacuum generator 2200 to independently evacuate the first sub-cavity 1001 and the second sub-cavity 1002. Two vacuum gauges 2300 are also present, used to monitor the vacuum level in the first sub-cavity 1001 and the second sub-cavity 1002.

[0148] While the present invention has been disclosed above, it is not limited thereto. Those skilled in the art can make various modifications and variations to the present invention without departing from its spirit and scope. Therefore, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention also intends to include such modifications and variations.
