Description
Technical Field
The invention relates to the field of machinery, in particular to a perfusion system.
Background
Micro-molding is a high precision nano-fabrication technique that shapes microstructures with the aid of microreplication dies. The micro-molding has the advantages of high replication precision, low cost, small residual stress and the like, and is widely applied to the preparation of nano-structures such as micro-gears, micro-needles, micro-fluidic chips, light guide plates and the like in various fields such as machinery, medical treatment, biology and the like.
The most critical step in micro-molding is mold filling, i.e., filling the replication liquid material into the molding cavity of the mold at a high filling ratio, which is a critical factor affecting the replication accuracy of the microstructure. The common mold filling modes include pressure filling, vacuum filling and the like. Wherein, pressure filling refers to pressing a filling material into a molding cavity of a mold by pressure. In this regard, the mold is generally manufactured by a metal integral molding method, but it is very difficult to process a structure having an equal aspect ratio and high precision like a microneedle mold by a metal integral molding method, and thus the microneedle mold is generally manufactured by a silicon material or a polymer material. However, silicon materials are generally brittle, polymer materials are softer, and have severe requirements on compressive stress, which is not suitable for mass production. In contrast, vacuum filling has low requirements on the material and size compatibility of the die, has more obvious advantages and is widely applied. The current vacuum filling method is to lay the raw material on the surface of the mold under normal pressure, and then vacuumize to remove the residual gas in the mold so that the raw material enters the microstructure of the mold. However, this method has problems, for example, when the thickness of the raw material laid is large, the residual gas is not completely removed in the process of removing the residual gas by vacuum pumping, so that the residual gas in the raw material eventually causes bubbles in the product, which affects the quality of the product, and the raw material laid is thick, which causes the problem of waste of the raw material, which increases the production cost. When the thickness of the raw materials is smaller, after the residual gas is removed by vacuumizing, the raw materials enter the forming cavity but cannot be fully filled into the forming cavity, so that the raw materials are lost, and the product performance is also affected. In addition, uneven thickness of raw materials is easy to occur in the raw material paving process, partial areas are large in thickness, partial areas are small in thickness, or the surfaces of the dies are uneven, and the consistency of raw materials entering the forming cavities is affected, and finally the quality of products is affected. In addition, the time for raw materials to enter the microstructure is long, and the production efficiency is reduced.

Fig. 3 shows a schematic structural diagram of a mold 200. As shown in fig. 3, the mold 200 includes a base 210, a recess 220 is provided on the base 210, a plurality of molding cavities 230 are provided in the recess 220, and a plurality of molding cavities 230 are arranged in an array.
When the vacuum infusion system is used to infuse the raw material into the mold 200, the mold 200 is disposed on the first stage 3100, and the first subchamber 1001 is in a vacuum environment. Then, when the first movement mechanism 5100 controls the first stage 3100 to move relative to the pouring assembly 4000 in the X-direction and/or the Y-direction, the pouring opening 4200 of the pouring assembly 4000 may be selectively aligned with one of the molding cavities 230 (i.e., the pouring opening 4200 and the molding cavity 230 aligned therewith have the same coordinates in the XY plane), and then, the first movement mechanism 5100 controls the pouring assembly 4000 to move in the negative Z-axis so that the pouring opening 4200 approaches the mold 200, and then, the molding cavity 230 may be poured with raw material. In particular, the pouring assembly 4000 is used for pouring raw materials into the forming cavity aligned with the pouring assembly 4000, and then the relative movement between the pouring assembly 4000 and the first carrier 3100 in the X direction and/or the Y direction is controlled again, so that the pouring port 4200 is aligned with the other forming cavity 230 which is not filled with vacuum, and the raw materials are poured. That is, after the pouring of the raw material into one molding cavity is completed, the relative movement between the pouring assembly 4000 and the first stage 3100 in the X-direction and/or the Y-direction is controlled again, so that the pouring port 4200 is aligned with the next non-vacuum-filled molding cavity 230 and is filled with the raw material until all the molding cavities 230 on the mold 200 are filled with the raw material, and finally, the positive movement of the pouring assembly 4000 in the Z-axis is controlled by the first movement mechanism 5100, so that the pouring port 4200 is far away from the mold 200. In this filling manner, each molding cavity can be accurately filled, waste of raw materials is reduced, raw materials directly enter the molding cavity, slow infiltration is not needed, the filling time is shortened, and the production cost is reduced. In addition, the pouring opening 4200 may further enable the raw materials to be sprayed in a water drop shape, in practical use, the operation parameters of the pouring opening 4200 may be set according to the opening size of the molding cavity 230, so that the diameter of the raw materials sprayed by the pouring opening 4200 is smaller than the opening size of the molding cavity 230, and thus the raw materials can be smoothly poured into the molding cavity 230, waste caused by spraying the raw materials to the outside of the molding cavity 230 is avoided, and the spraying times of the pouring opening to each molding cavity 230 are set according to the volume of the molding cavity 230, so that insufficient filling of the raw materials in each molding cavity 230 is avoided, uniformity of filling of the raw materials is improved, and quality of a final product is improved. Preferably, the fill port 4200 is a striker nozzle.
It should be noted that any suitable device or method may be used to determine whether the port 4200 is aligned with a molding cavity 230 in embodiments of the present invention. For example, when the injection system is first started, the relative movement function of the first movement mechanism 5100 is first used to determine the relative position relationship between the injection port 4200 and the first molding cavity 230, and to enable the injection port 4200 to inject the raw material once, and to observe whether the raw material accurately enters the one molding cavity 230, and if so, to consider that the injection port 4200 is aligned with the molding cavity 230. Thereafter, 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 injection port 4200 with the other molding cavities 230 in sequence. In other implementations, the alignment determination may be implemented by providing a laser alignment system, an optical alignment system, or other alignment systems in the prior art, which is not limited in this embodiment of the present invention. Since the alignment determination device or method is not an improvement point of the present invention, it will not be described in detail herein.
With continued reference to fig. 3, the plurality of molding cavities 230 are arranged in an array, and when the mold 200 is placed on the first stage 3100, the plurality of molding cavities 230 have a plurality of rows and a plurality of columns, wherein "rows" means that the plurality of molding cavities 230 are arranged parallel to the Y-axis and "columns" means that the plurality of molding cavities 230 are arranged parallel to the X-axis. With reference to fig. 1 and 2, in combination with fig. 4, the first movement mechanism 5100 includes a first driving component 5110, a second driving component 5120 and a third driving component 5130. The first driving assembly 5110 is connected to the first stage 3100 and is used for driving the first stage 3100 to perform a reciprocating linear motion along the X direction. The second driving assembly 5120 is connected to the third driving assembly 5130, and the priming assembly 4000 is connected to the third driving assembly 5130. The second driving assembly 5120 is configured to drive the third driving assembly 5130 and the priming assembly 4000 to perform a reciprocating rectilinear motion along the Y direction, and the third driving assembly 5130 is configured to drive the priming assembly 4000 to perform a reciprocating rectilinear motion along the Z direction.
In operation, the first driving assembly 5110 may first drive the first stage 3100 to move along the X direction to drive the mold 200 to move along the X direction synchronously, and align the molding cavities 230 of a row on the mold 200 with the filling ports 4200 along the X direction (i.e. the rows of the molding cavities 230 and the filling ports 4200 have the same coordinates along the X axis), then the second driving assembly 5120 drives the third driving assembly 5130 and the filling assembly 4000 to move along the Y direction, so that the filling ports 4200 are aligned with each of the molding cavities 230 of the row in the Y direction successively, i.e. the filling ports 4200 are aligned with each of the molding cavities 230 of the row successively (i.e. the filling ports 4200 and the molding cavities 230 aligned therewith have the same coordinates along the XY plane), and after each alignment, a corresponding action is performed by the filling assembly 4000 to complete the pouring of the raw materials of the respective molding cavities 230. When all of the molding cavities 230 of the one row are completely filled with the raw material, the first stage 3100 is driven to move in the X direction again by the first driving assembly 5110, so that the mold 200 moves synchronously in the X direction, and the molding cavities 230 of the other row are aligned with the filling ports 4200 in the X direction, so that the raw material can be filled into the molding cavities 230 of the other row. This allows for reduced misalignment by filling all of the molding cavities 230 on the mold 200 row by row. Furthermore, the first movement mechanism 5100 is arranged in such a manner that the volume of the first movement mechanism 5100 is reduced, which is advantageous in reducing the space of the first subchamber 1001. It should be understood that, in this embodiment, the second driving assembly 5120 may first drive the third driving assembly 5130 and the pouring assembly 4000 to move in the Y direction so that the pouring opening 4200 is aligned with a row of the molding cavities 230 in the Y direction, and then drive the first carrier 3100 to move in the X direction by the first driving assembly 5110 and drive the mold 200 to synchronously move in the X direction, so that each of the molding cavities 230 on the row is aligned with the pouring opening 4200 sequentially, that is, all of the molding cavities 230 are poured in the row.
With continued reference to fig. 1 and 2, the housing 1000 is preferably further formed with a second subchamber 1002, the second subchamber 1002 being selectively in communication with or isolated from the environment outside the housing 1000. A second mold interface 1002a is disposed within the second subchamber 1002. The vacuum generating system 2000 is also configured to evacuate the second subchamber 1002. The carrier assembly 3000 further comprises a second carrier 3200, wherein the second carrier 3200 is configured to be disposed in the second subchamber 1002, and a plurality of mold placement positions are further disposed on the second carrier 3200, and each mold placement position is configured to place one of the molds 200. The movement mechanism 5000 further includes a second movement mechanism 5200 and a third movement mechanism 5300. The second moving mechanism 5200 is at least partially disposed in the second subchamber 1002 and is configured to control the movement of the second carrier 3200 such that the second carrier 3200 enters the second subchamber 1002 or at least partially protrudes out of the housing 1000, and selectively causes one of the mold placement sites on the second carrier 3200 to coincide with the second mold interface site 1002a. As in the present embodiment, the aforementioned "the first subchamber 1001 is selectively communicated or isolated from the environment other than the first subchamber" means that the first subchamber 1001 is selectively communicated or isolated from the second subchamber 1002. A first mold connecting position 1001a is provided in the first subchamber 1001, and the first stage 3100 can move to the first mold connecting position 1001a along the X direction. The third movement mechanism 5300 is configured to transfer the mold 200 between the mold placement position of the second stage 3200 that coincides with the second mold delivery position 1002a and the first stage 3100 at the first mold delivery position 1001a. In fig. 1, the second carrier 3200 has two mold placement positions, and the two mold placement positions are provided with the mold 200, wherein one mold placement position coincides with the second mold connecting position 1002a, and the first carrier 3100 is located at the first mold placement position 1001.
Here, "the second stage 3200 enters the first subchamber 1001" means that the second stage 3200 entirely enters the second subchamber 1002. When the second stage 3200 is at least partially extended out of the housing 1000, at least one of the mold positions on the second stage 3200 is located outside the housing 1000.
The number of the mold placement positions on the second carrier 3200 may be two or more. Taking the example that two mold placement positions are provided on the second stage 3200, and when the second stage 3200 at least partially extends out of the housing 1000, one mold placement position is located outside the housing 1000, and the other mold placement position is still located in the second subchamber 1002, the use process of the filling system will be described. The two mould placing positions are a first mould placing position and a second mould placing position respectively. The use process comprises the following steps:
step S1, communicating the second subchamber 1002 with an environment outside the housing 1000.
In step S2, the second stage 3200 is controlled to at least partially protrude out of the housing 1000 by the second moving mechanism 5200 so that the first mold placement is located outside the housing 1000.
In step S3, one of the molds 200 is placed on the first mold placement site, and for convenience of description, the mold 200 placed on the first mold placement site will be hereinafter referred to as a first mold 200a (as labeled in fig. 1).
In step S4, the second stage 3200 is controlled to move by the second moving mechanism 5200, so that the second stage 3200 completely enters the second subchamber 1002 and the first mold placement position coincides with the second mold delivery position 1002a, that is, the first mold 200a is located at the second mold delivery position 1002 a.
Step S5, isolating the second subchamber 1002 from the environment outside the housing 1000.
In step S6, the first sub-chamber 1001 and the second sub-chamber 1002 are evacuated by the vacuum generating system 2000 until a predetermined vacuum degree is reached. It will be appreciated that if the first subchamber 1001 has been isolated from the second subchamber 1002 prior to this step and is at a specified vacuum, then only the second subchamber 1002 need be evacuated to the specified vacuum in this step. The vacuum level in the second subchamber 1002 is generally the same as the vacuum level in the first subchamber 1001, while the vacuum level of the first subchamber remains substantially unchanged during the priming operation and while the second subchamber 1002 is in the vacuum state.
Step S7, communicating the first subchamber 1001 with the second subchamber 1002.
In step S8, the first mold 200a at the second mold-transferring position 1002a is transferred to the first subchamber 1001 by the third moving mechanism 5300 and placed on the first stage 3100 at the first mold-transferring position 1001a.
In step S9, the third movement mechanism 5300 completely retracts the second subchamber 1002 and isolates the first subchamber 1001 from the second subchamber 1002.
Step S10: in the first subcavity 1001, the first moving assembly 5100 controls the first carrier 3100 to drive the first mold 200a and the pouring assembly 4000 to move, and the pouring assembly 4000 is utilized to pour the raw material into the first mold 200a, and after the raw material pouring of the first mold 200a is completed, the first carrier 310 is driven by the first driving assembly 5110 to drive the first mold 200a to move along the X direction and return to the first mold connecting position 1001a.
Step S11, communicating the second subchamber 1002 with an environment outside the housing 1000.
In step S12, the second stage 3200 is controlled to at least partially protrude out of the housing 1000 by the second moving mechanism 5200 so that the second mold placement is located outside the housing 1000.
In step S13, another mold 200 is placed on the second mold placement site. The mold 200 to be placed on the second mold placement site will hereinafter be referred to as a second mold 200b.
In step S14, the second motion mechanism 5200 controls the second carrier 3200 to completely enter the second sub-cavity 1002, so that the second mold 200b enters the second sub-cavity 1002, and the first mold placement position is still coincident with the second mold interface 1002 a.
In step S15, the second subchamber 1002 is isolated from the environment outside the housing 1000, and the vacuum generating system 2000 is used to vacuum the second subchamber 1002 to a predetermined vacuum level.
Step S16: the first subchamber 1001 is in communication with the second subchamber 1002.
In step S17, the first mold 200a, which has been filled with the raw material and is carried by the first stage 3200 already located at the first mold connecting position 1001a, is transferred to the first mold placing position by the third moving mechanism 5300.
In step S18, the second motion mechanism 5200 controls the motion of the second carrier 3200 so that the second mold displacement position coincides with the second mold delivery position 1002 a.
In step S19, the second mold 200b is transferred to the first stage 3100 still located at the first mold transferring position 1001a by the third moving mechanism 5300.
The third movement mechanism 5300 is completely retracted into the second sub-chamber 1002 to isolate the first sub-chamber 1001 from the second sub-chamber 1002 in step S20.
In step S21, the second mold 200b is filled with the material in the second subchamber 1002, and the first stage 3100 is returned to the first mold transferring position 1001a after the filling is completed.
Step S22, communicating the second subchamber 1002 with an environment outside the housing 1000.
In step S23, the second stage 3200 is controlled to move by the second moving mechanism 5200 so that the first mold placement is located outside the housing 1000.
And S24, blanking the first mold 200a with the vacuum filling completed on the first mold placing position.
In step S25, another first mold 200a that is not vacuum-filled is placed on the first mold placement position.
In step S26, the second stage 3200 is controlled to move by the second moving mechanism 5200, so that the first mold placement positions all enter the second subchamber 1002, and at this time, the second mold placement positions still overlap with the second mold connection position 1002 a.
Step S27: isolating the second subchamber 1002 from the environment outside the housing 1000 and evacuating the second subchamber 1002 to a prescribed vacuum level.
Step S28, communicating the first subchamber 1001 with the second subchamber 1002.
In step S29, the second mold 200b, which has completed the raw material pouring, is transferred to the second subchamber 1002 and placed in the second mold placement position by the third movement mechanism 5300.
In step S30, the second motion mechanism 5200 controls the motion of the second carrier 3200 so that the first mold placing position coincides with the second mold connecting position 1002 a.
In step S31, another first mold 200a in the first mold placement position is transferred onto the first stage 3200 by the third movement mechanism 5300.
In step S32, the third movement mechanism 5300 is completely retracted into the second sub-chamber 1002, isolating the first sub-chamber 1001 from the second sub-chamber 1002.
In step S33, the other first mold 200a is filled with the raw material in the first subchamber 1001, and after the other first mold 200a is filled with the raw material, the first carrier 3100 is returned to the first mold transfer position 1001a.
Step S34, communicating the second subchamber 1002 with an environment outside the housing 1000.
In step S35, the second stage 3200 is controlled to move by the second moving mechanism 5200 so that the second mold placement is located outside the housing 1000.
Step S36, unloading the second mold 200b that has been vacuum-filled.
In step S37, another second mold 200b that is not vacuum-filled is placed on the second mold placement site.
In step S38, the second stage 3200 is controlled to all enter the second subchamber 1002 by the second moving mechanism 5200, so that the second mold 200b enters the second subchamber 1002 while the first mold placement position is still coincident with the second mold interface 1002 a.
In step S39, the second subchamber 1002 is isolated from the environment outside the housing 1000, and the vacuum generating system 2000 is used to evacuate the second subchamber 1002 to a predetermined vacuum level.
The steps S16 to S39 are repeated to continuously perform raw material pouring on the plurality of molds 200.
In the above process, the steps S11 to S15 are performed during the execution of the step S10, the steps S22 to S27 are performed during the execution of the step S21, and the steps S34 to S39 are performed during the execution of the step S33.
As can be seen from the above use process, in the process of pouring the raw material into one of the molds 200 in the first subchamber 1001, the mold 200 having completed the pouring of the raw material can be blanked, and the mold 200 having not been poured with the raw material can be fed. That is, the filling process is performed in synchronization with the feeding process, and the filling process is performed in synchronization with the discharging process, and the first subchamber 1001 is not required to be vacuumized repeatedly, which can increase the tact of the whole production process, and further achieve the purpose of improving the production efficiency.
Next, the structure of each component of the perfusion system will be further described. It should be understood that the following description is only of alternative configurations of the various components and is not a necessary configuration, and therefore should not unduly limit this invention.
With continued reference to fig. 1 and 2, the housing 1000 includes a shell 1100 and a partition 1200. The housing 1100 forms an inner cavity in which the partition plate 1200 is disposed and divides the inner cavity into the first sub-cavity 1001 and the second sub-cavity 1002. The partition plate 1100 is provided with a first window (not shown) for communicating the first subchamber 1001 and the second subchamber 1002, and the housing 1100 is provided with a second window (not shown) for communicating with the second subchamber 1200.
In this embodiment, both the partition plate 1200 and the first window may be parallel to the XZ plane, that is, the first sub-chamber 1001 and the second sub-chamber 1002 are arranged along the Y direction. In addition, the second window may also be parallel to the XZ plane.
The irrigation system further comprises a closure assembly (not labeled in the figures) comprising a first closure assembly 6100 (as labeled in fig. 5-7) and a second closure assembly 6200. The first closing component 6100 is configured to selectively close or unblock the first window. It should be appreciated that when the first closing component 6100 closes the first window, the first subchamber 1001 is isolated from the second subchamber 1002 to form a closed chamber, and when the first closing component 6100 releases the closure of the first window, the first subchamber 1001 and the second subchamber 1002 communicate with each other, allowing the third movement mechanism 5300 to control the mold 200 to pass through the first window to transfer between the mold placement position of the second stage 3200 coinciding with the second mold interface 1002a and the first stage 3100 at the first mold interface 1001 a. The second closing component 6200 selectively closes or unblocks the second window. When the second closing assembly 6200 closes the second window, the second subchamber 1002 is isolated from the environment outside the housing 1000, and when the second closing assembly 6200 releases the closing of the second window, the second subchamber 1002 communicates with the environment outside the housing 1000 to allow the second stage 3200 to at least partially pass through the second window to protrude out of the housing 1000 or completely enter the second subchamber.
Fig. 5 shows a schematic structural diagram of a first closing component 6100 according to an embodiment. As shown in fig. 5, the first closing assembly 6100 includes a first sealing gate 6110 and a sixth driving portion 6120, where the sixth driving portion 6120 is connected to the housing 1000. The sixth driving part 6120 is further connected to the first sealing door 6110, and is configured to drive the first sealing door 6110 to perform a reciprocating linear motion in a direction parallel to the first window so as to cover or deviate from the first window. It should be appreciated that the first closing component 6100 further includes a sealing ring (not shown in the drawings), which surrounds the first window when the first closing component 6100 closes the first window, and is clamped between the partition 1200 and the first sealing door 6110, so as to ensure sealing effect. The "direction parallel to the first window" may be the first direction (i.e., X direction) or the third direction (i.e., Z direction), and the description will be given below taking the "direction parallel to the first window" as an example.
When the distance between the first sealing door 6110 and the partition plate 1200 is very small, the first sealing door 6110 moves in the Z direction, and when the first sealing door 6110 contacts with the sealing ring, the portion of the sealing ring contacting with the first sealing door 6110 is compressed, but this causes serious abrasion to the sealing ring, which is not beneficial for long-term use. Based on this, the first closing member 6100 further includes a seventh driving portion 6130, where the seventh driving portion 6130 is connected to the first sealing door 6110, and is configured to drive the first sealing door 6110 to reciprocate in a direction perpendicular to the first window so as to approach or separate from the partition 1200.

The second engaging portion 6150 has a U-shaped structure and includes two coupling plates 6151 disposed opposite to each other, and in this embodiment, the two coupling plates 6151 are disposed opposite to each other in the X direction and slidably connected to one of the second guiding portions 6140, respectively. The first sealing door 6110 is connected to both the engagement plates 6151. The sixth driving part 6120 includes a cylinder, which is called a first cylinder, and the cylinder body of the first cylinder may be disposed outside the housing 1000 and connected to the connection seat 6172, and the piston rod of the first cylinder extends in the negative direction of the Z direction and sequentially passes through the connection seat 6172, the first connection plate 6171, and the top wall of the housing 1000 and then is connected to the floating head 6174. By providing the floating head 6174, an assembly error due to a machining error between each component can be avoided. The second joint portion 6150 is driven to do reciprocating rectilinear motion along the Z direction in a limited manner by the two second guiding portions 6140 through the telescopic motion of the piston rod of the first cylinder, and further the first sealing door 6110 is driven to do reciprocating rectilinear motion along the Z direction so as to cover or deviate from the first window. By "covered" is meant herein that the projection of the first window is located entirely inside the projection of the first sealing door 6110 in a plane perpendicular to the Y-direction (i.e. XZ-plane). In addition, 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.
Further, each of the coupling plates 6151 is provided with a through hole (not labeled in the figure), and each through hole is provided with a bearing seat 6181.

The movement of the first sealing door 6110 in the Z direction and the movement in the Y direction may be performed simultaneously, or the movement in the Z direction may be performed first and then the movement in the Y direction may be performed.
It will be appreciated that the reverse operation may cause the first closing component 6100 to unblock the first window.

In this embodiment, the fifth direction is parallel to the first direction, that is, the fifth direction is an X direction, and herein, a positive direction of the X axis is a positive direction of the fifth direction. The transmission part 5213 includes a rack 5213a, a gear 5213b, and a link unit. The rack 5213a may be connected to a piston rod of the second cylinder in any suitable manner, the gear 5213b is rotatably connected to the housing 1000, and the gear 5213b is engaged with the rack 5212a, and the gear 5213b is connected to the first engaging portion 5220 through the link unit.

Conversely, when the piston rod of the second cylinder is retracted, the rack 5212a is moved in the negative direction of the X-axis to pull the gear 5212b to rotate in the counterclockwise direction, and thus the second coupling portion 5220 is pulled to move in the negative direction of the Y-axis by the link unit, and the second carrier 3200 is entirely introduced into the second subchamber 1002.

Two mold placement positions are respectively located on both ends of the second stage 3200 in the Y direction. In addition, the second die interface 1002a is also aligned with the second window in the X-direction. In this way, each time the fifth driving portion 5230 drives the second carrier 3200 to rotate 180 °, the two mold placement positions can be alternately overlapped with the second mold connecting position 1002a, wherein the mold placement position far from the second window is overlapped with the second mold connecting position 1002 a. In addition, in order to reduce the space of the second subchamber 1002, it is preferable that the fifth driving part 5230 reciprocally rotates the second carrier 3200 (i.e., first rotates 180 ° in a second predetermined direction, for example, clockwise so that one of the mold placement positions coincides with the second mold connecting position 1002a, and then rotates 180 ° in the opposite direction, for example, counterclockwise so that the other mold placement position coincides with the second mold connecting position 1002 a).

The third axis extends in the third direction, i.e. the Z-direction. In addition, to reduce the size of the interior cavity of the housing 1000, it is preferable that the seventh motor drives the third engagement portion 5311 in a reciprocating rotational motion about the third axis, i.e., the seventh motor drives the third engagement portion 5311 in a third predetermined direction, e.g., clockwise, by a predetermined angle such that the grasping assembly 5320 is transferred from the second subchamber 1002 to the first subchamber 1001, and the seventh motor returns the grasping assembly 5311 from the first subchamber 1001 to the second subchamber 1002 by driving the third engagement portion 5311 in a reverse, i.e., counterclockwise, direction by the predetermined angle.

Alternatively, the first section 5323b and the second section 5323c may also be integrally formed.
In addition, referring back to fig. 3, the mold 200 is provided with a positioning hole 240. The gripping assembly 5230 further includes a positioning shaft 5328, wherein the positioning shaft 5328 is connected to the movable plate 5321 and extends along the Z direction, and the positioning shaft 5328 is configured to be inserted into the positioning hole 240 on the mold 200, so that the position of the mold 200 is fixed by using the positioning shaft 5328, and displacement or play of the mold 200 in the relative movement (i.e., movement in a direction approaching to each other) of the first clamping jaw 5324a and the second clamping jaw 5324b is avoided, so that the first clamping jaw 5324a and the second clamping jaw 5324b are difficult to clamp the mold 200. Alternatively, the number of the positioning holes 240 is two or more, and preferably two or more of the 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.
The process of transferring the mold 200 located on the mold placement position of the second stage 3200 overlapping with the second mold delivery position 1002a to the first stage 3100 located on the first mold delivery position 1001a by using the third movement mechanism 5300 specifically includes:
First, the sixth screw 5322b is rotated in a fourth predetermined direction, for example, clockwise, by the eighth motor 5322a such that the movable plate 5321 is moved in the negative direction of the Z-axis (i.e., moved downward) by a predetermined distance, which is set in advance. 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 stage 3200 to avoid displacement or play of the mold 200. Then, the ninth motor 5323a drives the seventh screw rod to rotate in a fifth predetermined direction, for example, clockwise, so as to drive the first connection block 5324c and the second connection block 5324d to move in opposite directions, so as to drive the first clamping jaw 5324a and the second clamping jaw 5324b to move in opposite directions, and clamp the mold 200. Then, the eighth motor 5322a rotates reversely (i.e., in a counterclockwise direction) to drive the movable plate 5321 to move the predetermined distance in the positive direction of the Z-axis, and at this time, the clamping portion 5324 and the mold 200 move the predetermined distance together with the movable plate 5321 in the positive direction of the Z-axis (i.e., in an upward direction). Subsequently, the seventh motor drives the third engagement portion 5311 to rotate in a clockwise direction and carries the grasping assembly 5320 together through the first window, into the first subchamber 1002 and against the first mold interface 1001a, at which point the first stage 3100 has been moved in advance to the first mold interface 1001a. Next, the eighth motor 5222a drives the sixth screw 5322b to rotate in a clockwise direction, so that the movable plate 5321 moves a distance in a negative direction of the Z axis until the mold 200 contacts the first stage 3100. Then, the ninth motor 5323a drives the seventh screw to rotate in a counterclockwise direction, so that the first connection block 5324c and the second connection block 5324d are moved in a direction away from each other to release the mold 200. Then, the eighth motor 5323a drives the sixth screw 5322b to rotate in a counterclockwise direction to drive the movable plate 5321 to move in the positive direction of the Z axis, so that the positioning shaft 5328 is disengaged from the positioning hole 240 on the mold 200.
The process of transferring the mold 200 from the first stage 3100 at the first mold transferring position 1001a to the mold placing position of the second stage 3200 overlapping with the second mold transferring position 1002a by using the third moving mechanism 5300 is substantially the same as that described above, and will not be repeated here.

That is, the whole vacuum filling production process can be controlled by the controller, so that the filling process is intelligent, and errors or errors caused by manual operation are reduced. Further, the perfusion system may further include a display 9000 (as shown in fig. 1), where the display 9000 is communicatively connected to the controller 8000, each driving portion, and the perfusion module 4000, so as to display the set operation parameters and the actual operation parameters of the whole vacuum filling process, so that a user can monitor the perfusion process, and intervene in time when the perfusion system fails.
Further, the vacuum generating system 2000 includes a vacuum pump 2100, a vacuum valve 2200, and a vacuum gauge 2300, the number of the vacuum pumps 2000 being one, which has two vacuum pipes, which communicate with the first sub-chamber 1001 and the second sub-chamber 1002, respectively. The number of the vacuum valves 2200 is two, and the vacuum valves are respectively arranged on the two vacuum pipelines to respectively control the on-off of the first subchamber 1001 and the vacuum pump 2100, and the on-off of the second subchamber 1002 and the vacuum pump 2100, so that the vacuum valve 2200 can independently vacuumize the first subchamber 1001 and the second subchamber 1002. The number of the vacuum gauges 2300 is also two, and the two vacuum gauges 2300 are respectively used for monitoring the vacuum degrees of the first subchamber 1001 and the second subchamber 1002.
