Description

Technical Field

[0001] The invention relates to a breathing liquid carrier tray, in particular to a special breathing liquid carrier tray adapted to an automatic freeze dryer. Background Art

[0002] Vacuum freeze drying, referred to as freeze drying, is a drying method that freezes an object below the eutectic point and then removes moisture from the object by sublimation drying under high vacuum conditions. The freeze-dried powder obtained by this method has the advantages of being able to maintain the original activity of the object, maintaining the color of the object, and facilitating long-term storage. Therefore, freeze drying technology is widely used in food, medicine, biology, agriculture and other fields.

[0003] Among them, the freeze dryer is a necessary equipment required in the freeze drying process. At present, the freeze dryers seen on the market all require manual placement of the breathing liquid carrier plate. However, with the continuous development of automation and artificial intelligence technology, the freeze dryer is also developing in the direction of automation. For the automated freeze dryer, the breathing liquid carrier plate used for traditional manual operation cannot be adapted to the automatic grasping operation of the automated freeze dryer robot arm. Therefore, it is necessary to develop a special breathing liquid carrier plate that can be matched with the automated freeze dryer robot arm grasping part for automatic pick-up and placement operations. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a special breathing liquid carrier tray suitable for an automatic freeze dryer with a simple structure, convenient processing, small deformation and high cleaning rate. The special breathing liquid carrier tray is suitable for the automatic pick-and-place operation of the gripping part of the automatic freeze dryer robot arm.

[0005] In view of the fact that there is currently no breathing liquid carrier plate on the market that is suitable for automatic picking and placing by the gripping part of the automatic freeze dryer robot arm, the present invention designs a special breathing liquid carrier plate that is compatible with the gripping part to achieve the purpose of automatic loading and unloading of the breathing liquid carrier plate.

[0006] The breathing liquid-carrying tray currently available on the market includes: a tray with an open bottom formed by an integral top plate, a side frame and a bottom edge flange; the tray is made of plastic material and obtained by injection molding; a liquid-carrying membrane is heat-sealed and covered on the bottom edge flange, thereby sealing the open bottom of the tray; a mounting through hole and a feed through hole are opened on the top plate, a breathing membrane is heat-sealed and covered at the mounting through hole, a threaded tube with external threads is arranged at the feed through hole, and the threaded tube is located at the top of the top plate, a nut is screwed on the threaded tube and sealed by a sealing gasket sleeved on the threaded tube.

[0007] The special breathing liquid carrier plate adapted to the automatic freeze dryer of the present invention is a first flying wing and a second flying wing added to the original structure of the above-mentioned breathing liquid carrier plate. The specific structure is as follows: the first flying wing and the second flying wing are arranged on the top surface of the top plate; A plurality of first bearing plates are arranged on the first flying wing, and the bottom end surfaces of all the first bearing plates together constitute the bearing surface of the first flying wing; a plurality of first baffles are arranged on the top surface of the first flying wing, and the first baffles are distributed at intervals along the outer edge of the first flying wing; A plurality of second bearing plates are arranged on the second flying wing, and the bottom end surfaces of all the second bearing plates together constitute the bearing surface of the second flying wing; a plurality of second baffles are arranged on the top surface of the second flying wing, and the second baffles are distributed at intervals along the outer edge of the second flying wing.

[0008] When the automatic freeze dryer uses the gripping part of the mechanical arm to lift the special breathing liquid carrier tray, the bearing surface of the first wing and the bearing surface of the second wing are placed on the gripping part of the mechanical arm. For example, the gripping part of the mechanical arm can be two lifting rods. At this time, the bearing surface of the first wing and the bearing surface of the second wing are placed on the two lifting rods respectively. At this time, the first wing and the second wing bear all the weight of the entire tray.

[0009] Taking into account comprehensive factors such as the space occupied by the tray, the structure of the automated freeze dryer robot arm, and ease of processing, the tray described in this solution is preferably designed as a rectangular structure.

[0010] Taking into account that right angles will affect the cleaning rate and the amount of residue remaining in the tray after the material is discharged, this solution changes the right-angle connection between any two adjacent side panels of the four side panels of the side frame into a smooth connection with an arc surface. In addition, the right-angle connection between the four side panels of the side frame and the bottom plate is also changed into a smooth connection with an arc surface, so as to improve the overall cleaning rate of the tray and reduce the amount of residue after the material is discharged.

[0011] Since the first and second wings bear the weight of the entire pallet, in order to ensure the heat-sealed connection strength between the breathing membrane and the bottom plate, this solution sets the first wing at any edge of the bottom plate, and the second wing at the edge of the bottom plate opposite to the first wing. When the gripping part of the robot arm lifts the first and second wings, the heat-sealed connection between the bottom plate and the breathing membrane is subjected to an outward force of expansion due to the upward lifting force and the downward force generated by the weight of the pallet. This force will affect the heat-sealed connection strength of the breathing membrane. Therefore, moving the first and second wings outward to the edge can reduce the influence of this force and ensure the heat-sealed connection strength between the breathing membrane and the bottom plate.

[0012] In addition, in order to improve the overall strength of the breathing liquid carrier tray, the first flying wing, each first bearing plate, each first baffle, the second flying wing, each second bearing plate, and each second baffle are all integrally formed with the tray.

[0013] In addition, in order to ensure a smooth connection between the threaded tube and the bottom surface of the base plate to prevent materials or debris from accumulating at the connection between the threaded tube and the bottom surface during cleaning, the threaded tube is also integrally formed with the tray. At this time, there are no uneven corners at the connection between the two, but a smooth connection.

[0014] In summary, the threaded tube, the first flying wing, each first bearing plate, each first baffle, the second flying wing, each second bearing plate, each second baffle, and each connecting reinforcement rib are all made of the same material as the pallet, and the threaded tube, the first flying wing, each first bearing plate, each first baffle, the second flying wing, each second bearing plate, each second baffle, and each connecting reinforcement rib are all injection molded integrally with the pallet.

[0015] Further, the aforementioned dedicated breathing liquid carrier plate adapted for an automated freeze dryer, wherein the first flying wing is an L-shaped structure formed by integrally forming a first vertical support plate and a first horizontal support plate, and the first horizontal support plate is perpendicular to the first vertical support plate; the first vertical support plate is located at the edge of the bottom plate, each first carrier plate is distributed on the bottom surface of the first horizontal support plate, and the side portions of each first carrier plate are fixed to the first vertical support plate; The second flying wing is an L-shaped structure formed by an integrally formed second vertical support plate and a second horizontal support plate, and the second horizontal support plate is perpendicular to the second vertical support plate; the second vertical support plate is located at the edge of the bottom plate, and each second supporting plate is distributed on the bottom surface of the second horizontal support plate, and the side of each second supporting plate is fixed on the second vertical support plate.

[0016] Furthermore, in the aforementioned special breathing liquid carrier plate adapted for an automated freeze dryer, the first horizontal support plate is an outer folded edge folded outward relative to the first vertical support plate; the second horizontal support plate is an outer folded edge folded outward relative to the second vertical support plate.

[0017] Since the first flying wing and the second flying wing bear the weight of the entire pallet, the first flying wing and the second flying wing are prone to warping and deformation. In order to reduce the deformation of the first flying wing and the second flying wing, the present scheme provides a plurality of first reinforcing ribs between the inner side surface of the first vertical support plate and the top surface of the top plate; and a plurality of second reinforcing ribs between the inner side surface of the second vertical support plate and the top surface of the top plate; so as to improve the overall strength of the first flying wing and the second flying wing.

[0018] In addition, in order to further improve the overall strength of the first wing and the second wing, the first reinforcing rib and the second reinforcing rib are integrally formed with the tray. In summary, the first reinforcing rib and the second reinforcing rib are made of the same material as the tray, and the first reinforcing rib and the second reinforcing rib are integrally injection molded with the tray.

[0019] In addition, in order to further improve the overall strength of the first flying wing and the second flying wing, the present scheme also makes the following adjustments: among the first supporting plates arranged in a line from front to back on the bottom surface of the first horizontal support plate, the first supporting plate arranged at the front end is located at the front end edge of the first horizontal support plate, and the first supporting plate arranged at the rear end is located at the rear end edge of the first horizontal support plate; among the second supporting plates arranged in a line from front to back on the bottom surface of the second horizontal support plate, the second supporting plate arranged at the front end is located at the front end edge of the second horizontal support plate, and the second supporting plate arranged at the rear end is located at the rear end edge of the second horizontal support plate.

[0020] Furthermore, in the aforementioned special breathing liquid carrier plate adapted for the automatic freeze dryer, a plurality of positioning plates are arranged on the four side panels of the side frame, and the positioning plates are arranged in sequence and at intervals along the circumferential direction of the side frame.

[0021] A more optimal solution is to make each positioning piece integrally formed with the tray. In summary, each positioning piece is made of the same material as the tray, and each positioning piece is integrally injection molded with the tray.

[0022] The positions of the above-mentioned positioning pieces can be adjusted and designed according to the required positions of the laser limiter on the automatic freeze-drying plate. The positioning pieces can be used as positioning pieces for the laser limiter and can also play the role of reinforcing ribs.

[0023] Furthermore, the aforementioned special breathing liquid carrier plate adapted for the automatic freeze dryer is provided with at least one circle of downwardly protruding connection reinforcement ribs on the bottom surface of the top plate, and each connection reinforcement rib surrounds the periphery of the mounting through hole; when the breathing membrane is heat-sealed and covered at the mounting through hole, each connection reinforcement rib is in the heat-sealing area of ​​the breathing membrane.

[0024] Furthermore, in the aforementioned special breathing liquid carrier plate adapted for an automated freeze dryer, the cross-section of the connecting reinforcement rib is in a triangular shape.

[0025] The beneficial effects of the present invention are as follows: the special breathing liquid carrier plate of the above structure adapted to the automatic freeze dryer has the advantages of simple structure, convenient processing, small deformation, small amount of material residue, and adaptability to the automatic freeze dryer.

[0034] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0035] Example embodiments will be described more fully below with reference to the accompanying drawings, but the example embodiments may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. On the contrary, the purpose of providing these embodiments is to make the present disclosure thorough and complete and to enable those skilled in the art to fully understand the scope of the present disclosure.

[0036] For the convenience of description, the present invention is described as follows. Figure 1 The left-hand direction shown is defined as "front", with Figure 1 The right-hand direction shown is defined as "rear", with Figure 1 The horizontal center line shown is the boundary, the side of the component close to the horizontal center line is defined as "inside", and the side of the component away from the horizontal center line is defined as "outside". All directional words related to the directions of "front", "back", "inside" and "outside" in the present invention are based on this direction definition.

[0037] In the description of the present invention, it should be noted that the terms "front", "rear", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0038] like Figure 1 As shown, the special breathing liquid carrier tray adapted to the automatic freeze dryer described in this embodiment includes: a tray with an open bottom formed by a top plate 1, a side frame 2 and a bottom edge flange 3, and the tray is made of plastic material and obtained by injection molding. The liquid carrier film 4 is heat-sealed and covered on the bottom edge flange 3, so as to seal the open bottom of the tray. The liquid carrier film 4 can be made of modified PP material, and a transparent liquid carrier film 4 is usually used.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, a mounting through hole 102 and a feed through hole 101 are provided on the top plate 1, and the breathing membrane 5 is heat-sealed and covered at the mounting through hole 102. Here, the breathing membrane 5 can be directly heat-sealed on the bottom surface of the bottom plate 1. In order to improve the heat-sealed connection strength of the breathing membrane 5, at least one circle of downwardly protruding connection reinforcement ribs 17 can be provided on the bottom surface of the top plate 1. Figure 3 , Figure 4 and Figure 5 As shown, each connection reinforcement rib 17 surrounds the periphery of the installation through hole 102; when the breathing membrane 5 is heat-sealed and covered at the installation through hole 102, each connection reinforcement rib 17 is in the heat-sealed area of ​​the breathing membrane 5.

[0040] In this embodiment, the cross section of the connecting reinforcement rib 17 is preferably in a triangular shape.

[0041] The breathing membrane 5 described in this solution is a combined waterproof and breathable membrane structure composed of an inner waterproof and breathable sealing membrane and an outer mesh cloth located above the inner waterproof and breathable sealing membrane. The inner waterproof and breathable sealing membrane is preferably made of PTFE material.

[0042] like Figure 2 As shown, the threaded tube 6 with external threads is arranged at the feeding through hole 101, and the threaded tube 6 is located at the top of the top plate, and the nut 8 is screwed on the threaded tube 6 and sealed by the sealing gasket 7 sleeved on the threaded tube 6. At this time, if the threaded tube 6 is fixed at the feeding through hole 101 after hot pressing, there will be an uneven connection edge between the threaded tube 6 and the bottom surface of the bottom plate 1. The uneven connection edge is easy to cause materials or debris to accumulate at the connection edge during cleaning, affecting the material discharge rate and the cleaning rate. To solve this problem, the threaded tube 6 and the bottom plate 1 are integrally formed in this embodiment. At this time, there is no uneven connection edge at the connection between the two, but a smooth connection.

[0043] When the above-mentioned breathing liquid carrier tray is in use, the threaded tube 6 faces upwards and the liquid carrier membrane 4 is at the bottom. The liquid medicine is poured into the breathing liquid carrier tray through the pipe mouth of the threaded tube 6, and the liquid medicine is supported by the liquid carrier membrane 4. Then, the liquid medicine in the breathing liquid carrier tray is sealed by the nut 8 and the sealing gasket 7. Finally, the breathing liquid carrier tray is sent to the freeze dryer. During the freeze-drying process, the steam can penetrate outward through the inner waterproof and breathable sealing membrane and the outer mesh cloth.

[0044] After the freeze-drying is completed, the liquid medicine is converted into freeze-dried powder. The freeze-dried powder can be discharged by cutting the liquid carrier membrane 4 or by unscrewing the nut 8. When the liquid carrier membrane 4 is cut to discharge, the breathing liquid carrier plate is a disposable product. The nut 8 is unscrewed and discharged from the pipe mouth of the threaded tube 6. At this time, the breathing liquid carrier plate can be reused after cleaning and other operations. Which specific discharge method is used depends on the specific situation and is not required here.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a first wing 9 and a second wing 13 are arranged on the top surface of the top plate 1. A plurality of first bearing plates 12 are arranged on the first wing 9, and the bottom end surfaces of all the first bearing plates 12 together constitute the bearing surface of the first wing 9; a plurality of second bearing plates 16 are arranged on the second wing 13, and the bottom end surfaces of all the second bearing plates 16 together constitute the bearing surface of the second wing 13.

[0046] When the breathing liquid carrier plates are arranged in sequence, for example, when they are arranged one by one during the conveying process, in order to prevent the stacking of two adjacent breathing liquid carrier plates, in this embodiment, a plurality of first baffles 10 are arranged on the top surface of the first flying wing 9, and each first baffle 10 is distributed along the outer edge of the first flying wing 9. A plurality of second baffles 14 are arranged on the top surface of the second flying wing 13, and each second baffle 14 is distributed along the outer edge of the second flying wing 13.

[0047] Among them, the threaded tube 6, the first flying wing 9, each first bearing plate 12, each first baffle 10, the second flying wing 13, each second bearing plate 16, each second baffle 14, and each connecting reinforcement rib 17 are all made of the same material as the tray, and the threaded tube 6, the first flying wing 9, each first bearing plate 12, each first baffle 10, the second flying wing 13, each second bearing plate 16, each second baffle 14, and each connecting reinforcement rib 17 are all integrally injection molded with the tray to further improve the overall strength of the breathing liquid carrier.

[0048] When the automatic freeze dryer uses the gripping part of the mechanical arm to lift the special breathing liquid carrier tray, the bearing surface of the first wing 9 and the bearing surface of the second wing 13 are placed on the gripping part of the mechanical part. At this time, the first wing 9 and the second wing 13 bear the weight of the entire tray.

[0049] Taking into account factors such as the space occupied by the tray, the structure of the automated freeze dryer robot arm, and processing, in this embodiment, the tray is preferably a rectangular structure. At this time, the side frame 2 is composed of four side panels. Considering the material discharge rate and the tray cleaning rate, this embodiment makes the side frames 2 have two adjacent side panels connected smoothly by arc surfaces. In addition, the side frame 2 and the bottom plate 1 are also connected smoothly by arc surfaces.

[0050] Since the first wing 9 and the second wing 13 bear the weight of the entire pallet, in order to ensure the heat-sealed connection strength between the breathing membrane 5 and the base plate 1, this solution sets the first wing 9 at any edge of the base plate 1, and the second wing 13 at the edge of the base plate 1 on the opposite side of the first wing 9.

[0051] When the grabbing part of the robot arm lifts the first flying wing 9 and the second flying wing 13, the heat-sealed connection between the bottom plate 1 and the breathing membrane 5 is subjected to an outward force of expansion due to the upward lifting force and the downward force generated by the weight of the pallet. This force will affect the strength of the heat-sealed connection of the breathing membrane. Therefore, moving the first flying wing 9 and the second flying wing 13 outward to the edge can reduce the influence of this force and ensure the strength of the heat-sealed connection between the breathing membrane 5 and the bottom plate 1.

[0052] In this embodiment, the first flying wing 9 and the second flying wing 13 are preferably L-shaped structures, and the specific structure is described as follows: like Figure 1 , Figure 3 and Figure 4 As shown, the first flying wing 9 is an L-shaped structure formed by an integral molding of a first vertical support plate 902 and a first horizontal support plate 901, and the first horizontal support plate 901 is perpendicular to the first vertical support plate 902. The first vertical support plate 902 is located at the edge of the bottom plate 1, and each first bearing plate 12 is distributed on the bottom surface of the first horizontal support plate 901, and the side of each first bearing plate 12 is fixed to the first vertical support plate 902.

[0053] like Figure 1 , Figure 2 and Figure 3 As shown, the second flying wing 13 is an L-shaped structure formed by the second vertical support plate 1302 and the second horizontal support plate 1301, and the second horizontal support plate 1301 is perpendicular to the second vertical support plate 1302. The second vertical support plate 1302 is located at the edge of the bottom plate 1, and each second bearing plate 16 is distributed on the bottom surface of the second horizontal support plate 1301, and the side of each second bearing plate 16 is fixed on the second vertical support plate 1302.

[0054] In this embodiment, the first flying wing 9 and the second flying wing 13 are preferably outward-turned structures, and the specific structure is described as follows: the first horizontal support plate 901 is an outer folded edge folded outward relative to the first vertical support plate 902; the second horizontal support plate 1301 is an outer folded edge folded outward relative to the second vertical support plate 1302. This arrangement can also improve the external cleaning cleanliness of the respiratory liquid carrier plate and the subsequent sterilization effects.

[0055] The tray and the components integrally formed with the tray are made of plastic material, which is very easy to deform when exposed to cold or heat. Since the first wing 9 and the second wing 13 are the load-bearing parts that bear the weight of the entire breathing liquid carrier tray, in order to further reduce the deformation of the first wing 9 and the second wing 13, a plurality of first reinforcing ribs 11 are arranged between the inner side surface of the first vertical support plate 902 and the top surface of the top plate 1, and a plurality of second reinforcing ribs 15 are arranged between the inner side surface of the second vertical support plate 1302 and the top surface of the top plate 1.

[0056] The first reinforcing rib 11 may be a triangular support plate structure 11a located in the corner formed by the first vertical support plate 902 and the top plate 1, such as Figure 4 As shown, the second reinforcing rib 15 can also be a triangular support plate structure 11a.

[0057] The first reinforcing rib 11 may also be a support plate structure 11b located at a corner formed by the first vertical support plate 902 and the top plate 1, and the top of the first reinforcing rib 11 may directly extend to the top of the first vertical support plate 902. Figure 6 and Figure 7As shown, the second reinforcing rib 15 can also be a supporting plate structure 11b.

[0058] Considering that integral molding has higher strength, it is preferred that the first reinforcing rib 11 and the second reinforcing rib 15 are made of the same material as the pallet, and the first reinforcing rib 11 and the second reinforcing rib 15 are integrally injection molded with the pallet.

[0059] In order to further reduce the deformation of the first flying wing 9 and the second flying wing 13, the distribution of each first supporting plate 12 and each second supporting plate 16 is adjusted as follows in this embodiment: The first supporting plates 12 are arranged in a line from front to back on the bottom surface of the first horizontal supporting plate 901 in sequence and at intervals. The first supporting plate 12a arranged at the front end is located at the front edge of the first horizontal supporting plate 901, and the first supporting plate 12b arranged at the rear end is located at the rear edge of the first horizontal supporting plate 901. Figure 3 shown.

[0060] The second supporting plates 16 are arranged in a line from front to back on the bottom surface of the second horizontal supporting plate 1301 in sequence and at intervals. The second supporting plate 16a arranged at the front end is located at the front edge of the second horizontal supporting plate 1301, and the second supporting plate 16b arranged at the rear end is located at the rear edge of the second horizontal supporting plate 1301. Figure 4 shown.

[0061] The first supporting plate 12a arranged at the front end, the first supporting plate 12b arranged at the rear end, the second supporting plate 16a arranged at the front end, and the second supporting plate 16b arranged at the rear end play a key role in preventing the first flying wing 9 and the second flying wing 13 from deforming.

[0062] In this embodiment, Figure 1 and Figure 2 As shown, a plurality of positioning pieces are provided on the four side panels of the side frame 2, each positioning piece is made of the same material as the tray, and each positioning piece is integrally injection-molded with the tray.

[0063] For the convenience of description, the positioning pieces on the long sides of the side frame 2 are defined as first positioning pieces 18a, and the positioning pieces on the short sides of the side frame 2 are defined as second positioning pieces 18b. The first positioning pieces 18a are arranged in sequence along the long side of the side frame 2, and the second positioning pieces 18b are arranged in sequence along the short side of the side frame.

[0064] The positions of the first positioning pieces 18a and the second positioning pieces 18b are set according to actual needs and are not limited here. The positions of the positioning pieces can be adjusted and designed according to the required positions of the laser limiter of the breathing liquid carrier plate on the automatic freeze dryer, and can be used as positioning pieces for the laser limiter and also as reinforcing ribs.

[0065] In actual operation, the second positioning pieces 18b in the short side direction can be used as positioning components for laser limiting, and the first positioning pieces 18a in the long side direction can be used as reinforcing rib components. Alternatively, the second positioning pieces 18b in the long side direction can be used as positioning components for laser limiting, and the first positioning pieces 18a in the short side direction can be used as reinforcing rib components.

[0066] It is also possible to select a few of the second positioning pieces 18b in the short side direction as positioning components for laser limiting, and the remaining second positioning pieces 18b and the first positioning pieces 18a in the long side direction are all used as reinforcing rib components.

[0067] It is also possible to select several first positioning pieces 18a in the long side direction as positioning components for laser limiting, and the remaining first positioning pieces 18a and the second positioning pieces 18b in the short side direction are all used as reinforcing rib components.

[0068] It is also possible to select several first positioning pieces 18a in the long side direction and several second positioning pieces 18b in the short side direction as positioning components for laser limiting, and the remaining first positioning pieces 18a and second positioning pieces 18b are used as reinforcing rib components.

[0069] The special breathing liquid carrier plate of the above structure adapted to the automatic freeze dryer has the advantages of simple structure, convenient processing, small deformation, small amount of material residue, and adaptability to the automatic freeze dryer.

[0070] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any modification or equivalent change made based on the technical essence of the present invention still falls within the scope of protection required by the present invention.
