Description

Technical Field

[0001] The present invention relates to the technical field of stem cell culture, and particularly relates to an automatic dispensing device for a stem cell culture medium. Background Art

[0002] In the field of stem cell research and application, the preparation and dispensing of culture media are extremely crucial links. With the development of biomedicine, the demand for stem cells is increasing continuously, and the requirements for the stem cell culture environment are also becoming increasingly strict. Traditional stem cell culture dishes are usually placed in single-layer or multi-layer incubators for storage and culture. However, in actual operation, especially when it comes to the design of multi-layer dispensing boxes, there are many challenges.

[0003] Firstly, when taking and placing culture dishes at specific positions in the multi-layer dispensing boxes in the prior art, it is often necessary to move the culture dishes on other layers, which not only increases the operation difficulty and time cost, but also may cause unnecessary collisions or slides between the culture dishes, thus affecting the accuracy of experimental results. Secondly, when opening the dispensing box to take and place a certain culture dish, external gas may enter the inside of the box, causing other unoperated culture dishes to be exposed to the air that may contain pollutants, increasing the risk of contamination. This kind of contamination may come from microorganisms, dust particles or other chemical substances in the air, which can interfere with the normal growth and differentiation process of stem cells and even lead to the failure of the experiment.

[0004] Therefore, an automatic dispensing device for a stem cell culture medium is needed to solve the above problems. Summary of the Invention

[0005] In order to solve the above problems, that is, to solve the problem that when taking and placing culture dishes at specific positions in the multi-layer dispensing boxes in the prior art, it is easy to cause collisions among multiple culture dishes and easy to contaminate other unoperated culture dishes, the present invention provides an automatic dispensing device for a stem cell culture medium.

[0006] An automatic dispensing device for a stem cell culture medium includes a culture dish, and also includes a dispensing box and a box cover threadedly installed on the top of the dispensing box. An installation mechanism is arranged inside the dispensing box. A plurality of stacked turntables are rotatably installed on the installation mechanism. A driving mechanism is arranged on the installation mechanism and is drivingly connected to the turntables. The top end of the driving mechanism penetrates through the box cover. A plurality of placement grooves are formed on the outer side of the top of the turntable. The culture dish is placed in the placement groove. A plurality of access holes are formed through the side wall of the dispensing box. The plurality of access holes and the placement grooves on the multiple turntables are located on the same horizontal plane. An extraction mechanism that is mutually linked is arranged in the access hole and in the placement groove.

[0007] Preferably, the installation mechanism includes a central shaft, a chassis, and a top plate. The top view of the chassis is rectangular. An upper surface of the bottom wall of the sub-packaging box is provided with a chassis groove matching the chassis. The chassis is placed in the chassis groove. A bottom end of the central shaft is coaxially and fixedly installed on the upper surface of the chassis. A top end of the central shaft penetrates through the box cover and extends outside the sub-packaging box. The number of the turntables is two. Through holes are formed through the middle positions of the two turntables. The central shaft penetrates through the through holes. The top plate is coaxially and fixedly installed on an outer surface of the central shaft. A lower surface of the top plate contacts an upper surface of the upper turntable. When the culture dish is completely placed in the placement groove, the culture dish is completely located below the top plate. By clamping the chassis in the square chassis groove, the central shaft can be prevented from rotating with the turntable. By providing the top plate and making the culture dish completely located below the top plate after being completely placed in the placement groove, when the turntable is outside the sub-packaging box and multiple culture dishes are placed in the placement groove one by one, the culture dishes placed in the placement groove first can be prevented from being contaminated. By installing the turntable on the central shaft that can be taken out of the sub-packaging box, it is convenient to place the culture dish into the placement groove. The setting of the placement groove can prevent the culture dishes from colliding with each other.

[0008] Preferably, second retraction cavities are respectively formed at positions close to the outer ends on both sides of the placement groove. A blocking slide plate is slidably installed in the second retraction cavity through a third abutting spring. A part of the blocking slide plate extends into the placement groove. A top view of the blocking slide plate located in the placement groove is triangular. The setting of the blocking slide plate can not only prevent the culture dish from sliding outwards, but also the slidably arranged blocking slide plate will not affect the placement and removal of the culture dish.

[0009] Preferably, an upper tooth groove is coaxially formed at a position close to the middle on an inner surface of the through hole of the upper turntable, and a lower tooth groove is coaxially formed at a position close to the middle on an inner surface of the through hole of the lower turntable.

[0010] Preferably, the driving mechanism includes a slide rod cavity coaxially formed inside the central shaft. A driving rod is slidably installed in the slide rod cavity. A top end of the driving rod penetrates through the box cover and extends outside the sub-packaging box. A first abutting spring is arranged at a bottom end of the driving rod. A meshing cavity is coaxially formed inside the central shaft. The meshing cavity is communicated with the slide rod cavity. A first bevel gear ring and a second bevel gear ring are coaxially and fixedly installed on an outer surface of the driving rod. A tooth surface of the first bevel gear ring faces upwards, and a tooth surface of the second bevel gear ring faces downwards.

[0011] Preferably, a first gear and a second gear are rotatably installed inside the central axis, and part of the first gear and part of the second gear extend outside the central axis. The first gear is meshed and connected with the upper tooth groove, and the second gear is meshed and connected with the lower tooth groove. A first bevel gear is coaxially and fixedly installed at the bottom of the first gear, and a second bevel gear is coaxially and fixedly installed at the top of the second gear. A part of the first bevel gear and a part of the second bevel gear extend into the meshing cavity. By setting a driving rod that can slide up and down, when the driving rod is not pressed down, the first bevel gear ring is meshed and connected with the first bevel gear, and rotating the driving rod can drive the upper turntable to rotate. Pressing down the driving rod makes the second bevel gear ring meshed and connected with the second bevel gear, and rotating the driving rod can drive the lower turntable to rotate. This setting enables the operator to rotate the two turntables respectively, and the operation is convenient.

[0012] Preferably, two first retraction cavities are symmetrically formed at a position near the bottom of the outer surface of the turntable. A top plate is slidably installed inside the first retraction cavity through a second abutting spring, and the outer end of the top plate abuts against the inner surface of the sub-packaging box. By abutting the side wall of the sub-packaging box with the top plate, the friction between the turntable and the sub-packaging box can be increased, and it can prevent one turntable from driving the other turntable to rotate when one turntable rotates.

[0013] Preferably, two of the above-mentioned pick-and-place holes penetrate through the side wall of the sub-packaging box. The taking-out mechanism includes a first pulling hole, which is formed below the pick-and-place hole. The top of the first pulling hole is connected to the pick-and-place hole through a first communication sliding hole. A first pull rod is slidably installed inside the first pulling hole. A sealing sliding cover matching the pick-and-place hole is fixedly installed on the upper surface of the first pull rod near the outer end through a connecting rod. Sliding the sealing sliding cover in the pick-and-place hole can effectively isolate external pollutants.

[0014] Preferably, the taking-out mechanism further includes a second pulling hole, which is formed below the placement groove. The top of the second pulling hole is connected to the placement groove through a second communication sliding hole. A second pull rod is slidably installed inside the second pulling hole. The inner end of the second pull rod is connected to the inner end of the second pulling hole through a tension spring. A push plate is slidably installed inside the placement groove, and the bottom end of the push plate is fixedly connected to the inner end of the outer surface of the second pull rod through a connecting sliding plate.

[0015] Preferably, jacks are formed at the outer ends of the second draw rods, clamping grooves are formed on both sides of the jacks near the inner ends, clamping blocks matching the clamping grooves are slidably mounted on both sides of the first draw rod near the inner end, pressing plates are slidably mounted on both sides of the first draw rod near the outer end, two sliding cavities are formed inside the first draw rod, the inner ends of the clamping blocks and the pressing plates on the same side of the first draw rod extend into one of the sliding cavities, first limiting sliding grooves are formed on the sides of the pressing plates, first limiting sliding blocks are fixedly mounted on one side of the pressing plates, a fifth abutting spring is arranged on the side of the first limiting sliding block close to the other first limiting sliding block, the inner ends of the clamping blocks and the pressing plates on the same side of the first draw rod are connected through connecting plates, and the connecting plates slide inside the sliding cavities; by providing the taking-out mechanism, when a certain culture dish needs to be taken out, after aligning the placement groove corresponding to this culture dish with the picking hole, only need to press the pressing plate inward to retract the clamping block, then push the first draw rod inward so that the inner end of the first draw rod is inserted into the jack, then release the pressing plate to make the clamping block snap into the clamping groove, and then pull the push plate outward through the first draw rod and the second draw rod, and the push plate will push out the culture dish. This setting not only facilitates taking out a single culture dish, but also prevents other culture dishes from contacting the external air during operation, and can prevent other culture dishes from being contaminated.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. By clamping the chassis in the square chassis groove, the present invention can prevent the central axis from rotating with the turntable. By providing the top plate and making the culture dish completely located below the top plate after being completely placed in the placement groove, when the turntable is outside the sub-packaging box and multiple culture dishes are placed in the placement groove one by one, the culture dishes placed in the placement groove first can be prevented from being contaminated. By mounting the turntable on the central axis that can take out the sub-packaging box, it is convenient to place the culture dish into the placement groove, and the setting of the placement groove can prevent the culture dishes from colliding with each other.

[0018] 2. By providing a driving rod that can slide up and down, when the driving rod is not pressed down, the first bevel gear ring is meshed and connected with the first bevel gear, and rotating the driving rod can drive the upper turntable to rotate. Pressing down the driving rod makes the second bevel gear ring meshed and connected with the second bevel gear, and rotating the driving rod can drive the lower turntable to rotate. This setting enables the operator to rotate the two turntables respectively, and the operation is convenient.

[0019] 3. By providing a taking-out mechanism in the present invention, when it is necessary to take out a certain culture dish, after aligning the placement groove corresponding to this culture dish with the picking hole, only need to press the pressing plate inward to retract the clamping block, then push the first pull rod inward so that the inner end of the first pull rod is inserted into the insertion hole, then release the pressing plate to make the clamping block snap into the clamping groove, and then pull the push plate outward through the first pull rod and the second pull rod, and the push plate will push out the culture dish. This setting not only facilitates taking out a single culture dish, but also prevents other culture dishes from coming into contact with the external air during operation, and can prevent other culture dishes from being contaminated.

[0033] The preferred implementation modes of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation modes are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0034] As Figures 1-4 shown, the embodiment of the present invention discloses an automatic sub-packaging device for a stem cell culture medium, which includes a Petri dish 1, and also includes a sub-packaging box 2 and a box cover 3 threadedly installed on the top of the sub-packaging box 2. An installation mechanism is arranged inside the sub-packaging box 2. A plurality of stacked turntables 4 are rotatably installed on the installation mechanism. A driving mechanism for drivingly connecting with the turntable 4 is arranged on the installation mechanism. The top end of the driving mechanism penetrates through the box cover 3. A plurality of placement grooves 5 are opened on the outer side of the top of the turntable 4. The Petri dish 1 is placed in the placement groove 5. A plurality of pick-up and placement holes 6 are penetrated through the side wall of the sub-packaging box 2. The plurality of pick-up and placement holes 6 are respectively on the same horizontal plane as the placement grooves 5 on the multi-layer turntables 4. A taking-out mechanism that is mutually linked is arranged in the pick-up and placement hole 6 and in the placement groove 5.

[0035] As Figures 3-5As shown in the figure, the installation mechanism includes a central shaft 7, a chassis 8, and a top plate 9. The top view of the chassis 8 is rectangular. An upper surface of the bottom wall of the sub-packaging box 2 is provided with a chassis groove that matches the chassis 8. The chassis 8 is placed in the chassis groove. A bottom end of the central shaft 7 is coaxially and fixedly installed on the upper surface of the chassis 8. A top end of the central shaft 7 penetrates through the box cover 3 and extends outside the sub-packaging box 2. The number of turntables 4 is two. Through holes 10 are formed through the middle positions of the two turntables 4. The central shaft 7 is arranged through the through holes 10. The top plate 9 is coaxially and fixedly installed on the outer surface of the central shaft 7. A lower surface of the top plate 9 contacts an upper surface of the upper turntable 4. When the culture dish 1 is completely placed in the placement groove 5, the culture dish 1 is completely located below the top plate 9. By clamping the chassis 8 in the square chassis groove, the central shaft 7 can be prevented from rotating with the turntable 4. By providing the top plate 9 and making the culture dish 1 completely located below the top plate 9 after being completely placed in the placement groove 5, when the turntable 4 is outside the sub-packaging box 2 and multiple culture dishes 1 are placed in the placement groove 5 one by one, the culture dish 1 placed in the placement groove 5 first can be prevented from being contaminated. By installing the turntable 4 on the central shaft 7 that can take out the sub-packaging box 2, it is convenient to place the culture dish 1 into the placement groove 5. The arrangement of the placement groove 5 can prevent the culture dishes 1 from colliding with each other.

[0036] As Figure 4 and Figure 8 shown, second retraction cavities 11 are respectively formed at positions near the outer ends on both sides of the placement groove 5. A blocking slide plate 13 is slidably installed in the second retraction cavity 11 through a third abutting spring 12. A part of the blocking slide plate 13 extends into the placement groove 5. A top view of the blocking slide plate 13 located in the placement groove 5 is triangular. The arrangement of the blocking slide plate 13 can not only prevent the culture dish 1 from sliding outwards, but also the slidably arranged blocking slide plate 13 will not affect the placement and removal of the culture dish 1.

[0037] As Figure 4 shown, an upper tooth groove 14 is coaxially formed at a position near the middle on an inner surface of the through hole 10 of the upper turntable 4, and a lower tooth groove is coaxially formed at a position near the middle on an inner surface of the through hole 10 of the lower turntable 4.

[0038] As Figure 6 shown, the driving mechanism includes a slide rod cavity 15. The slide rod cavity 15 is coaxially formed inside the central shaft 7. A driving rod 16 is slidably installed in the slide rod cavity 15. A top end of the driving rod 16 penetrates through the box cover 3 and extends outside the sub-packaging box 2. A bottom end of the driving rod 16 is provided with a first abutting spring 17. A meshing cavity 18 is coaxially formed inside the central shaft 7. The meshing cavity 18 is communicated with the slide rod cavity 15. A first bevel gear ring 19 and a second bevel gear ring 20 are coaxially and fixedly installed on an outer surface of the driving rod 16. A tooth surface of the first bevel gear ring 19 faces upwards, and a tooth surface of the second bevel gear ring 20 faces downwards.

[0039] As Figures 5-6As shown, a first gear 21 and a second gear 22 are rotatably installed inside the central axis 7. Part of the first gear 21 and part of the second gear 22 both extend outside the central axis 7. The first gear 21 is meshed and connected with the upper tooth groove 14, and the second gear 22 is meshed and connected with the lower tooth groove. A first bevel gear 23 is coaxially and fixedly installed at the bottom of the first gear 21, and a second bevel gear 24 is coaxially and fixedly installed at the top of the second gear 22. A part of the first bevel gear 23 and a part of the second bevel gear 24 both extend into the meshing cavity 18. By providing a driving rod 16 that can slide up and down, when the driving rod 16 is not pressed down, the first bevel gear ring 19 is meshed and connected with the first bevel gear 23. Rotating the driving rod 16 can drive the upper turntable 4 to rotate. Pressing down the driving rod 16 makes the second bevel gear ring 20 meshed and connected with the second bevel gear 24. Rotating the driving rod 16 can drive the lower turntable 4 to rotate. This setting enables the operator to rotate the two turntables 4 respectively, and the operation is convenient.

[0040] As Figure 4 and Figure 7 shown, two first retraction cavities 25 are symmetrically opened at a position near the bottom of the outer surface of the turntable 4. A top plate 27 is slidably installed inside the first retraction cavity 25 through a second abutting spring 26. The outer end of the top plate 27 abuts against the inner surface of the sub-packaging box 2. By abutting the side wall of the sub-packaging box 2 with the top plate 27, the friction between the turntable 4 and the sub-packaging box 2 can be increased, and it can prevent one turntable 4 from driving the other turntable 4 to rotate when one of the turntables 4 rotates.

[0041] As Figures 1-2 shown, two access holes 6 are penetrated through the side wall of the sub-packaging box 2. The taking-out mechanism includes a first pulling hole 28, which is opened below the access hole 6. The top of the first pulling hole 28 is connected to the access hole 6 through a first communicating sliding hole 29. A first pull rod 30 is slidably installed inside the first pulling hole 28. A sealing sliding cover 32 matching the access hole 6 is fixedly installed at a position near the outer end of the upper surface of the first pull rod 30 through a connecting rod 31. Sliding the sealing sliding cover 32 inside the access hole 6 can effectively isolate external pollutants.

[0042] As Figure 4 and Figure 9 shown, the taking-out mechanism further includes a second pulling hole 33, which is opened below the placing groove 5. The top of the second pulling hole 33 is connected to the placing groove 5 through a second communicating sliding hole 34. A second pull rod 35 is slidably installed inside the second pulling hole 33. The inner end of the second pull rod 35 is connected to the inner end of the second pulling hole 33 through a tension spring 36. A push plate 37 is slidably installed inside the placing groove 5. The bottom end of the push plate 37 is fixedly connected to the inner end of the outer surface of the second pull rod 35 through a connecting sliding plate 38.

[0043] As Figures 9-11As shown in the figure, a jack 39 is provided at the outer end of the second draw bar 35. Slots 40 are provided on both sides of the jack 39 near the inner end. Blocks 41 that match the slots 40 are slidably installed on both sides of the first draw bar 30 near the inner end. Pressing plates 42 are slidably installed on both sides of the first draw bar 30 near the outer end. Two sliding chambers 43 are provided inside the first draw bar 30. The inner ends of the blocks 41 and the pressing plates 42 on the same side of the first draw bar 30 extend into one of the sliding chambers 43. A first limiting sliding groove 44 is provided on the side of the pressing plate 42. A first limiting slider 45 is fixedly installed on one side of the pressing plate 42. A fifth abutting spring 46 is provided on the side of the first limiting slider 45 close to the other first limiting slider 45. The inner ends of the blocks 41 and the pressing plates 42 on the same side of the first draw bar 30 are connected by a connecting plate 47. The connecting plate 47 slides inside the sliding chamber 43. By providing the taking-out mechanism, when it is necessary to take out a certain culture dish 1, after aligning the corresponding placing groove 5 of this culture dish 1 with the taking-in and taking-out hole 6, only need to press the pressing plate 42 inward to retract the block 41, and then push the first draw bar 30 inward so that the inner end of the first draw bar 30 is inserted into the jack 39, and then release the pressing plate 42 to make the block 41 snap into the slot 40, and then pull the push plate 37 outward through the first draw bar 30 and the second draw bar 35, and the push plate 37 will push out the culture dish 1. This setting not only facilitates taking out a single culture dish 1, but also does not cause other culture dishes 1 to contact the external air during operation, and can prevent other culture dishes 1 from being contaminated.
