Description

Technical Field

[0001] This application relates to the field of cell culture technology, and for example to a bottle clamping mechanism. Background Art

[0002] In highly automated cell culture equipment, operations such as opening and closing caps and pipetting of culture flasks can be performed automatically. Automated operation of culture flasks relies on accurate positioning and secure clamping.

[0003] To secure culture flasks, a circular tube clamping mechanism is disclosed in related technologies. This mechanism includes a mounting base, multiple clamping members, multiple pressing members, and a drive module. Each clamping member is housed within the mounting base and has clamping holes for holding the circular tube. One end of each pressing member is fixedly connected to the mounting base, and the other end of each pressing member contacts or abuts against the clamping member. The pressing members are used to adjust the clamping force of the clamping members. The drive module includes a drive mechanism and multiple drive blocks connected to the drive mechanism. The drive mechanism can drive each drive block to move, and each drive block cooperates with each pressing member to drive the clamping member to clamp the circular tube. The clamping members in the related technologies include a first clamping block and a second clamping block connected by a second elastic member. The drive module drives the pressing members to move, thereby compressing the second elastic member, so that the first and second clamping blocks approach and clamp the circular tube.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] When the drive module moves multiple drive blocks, it squeezes the second elastic element through the clamping component, causing the first and second clamping blocks to overcome the elastic force of the second elastic element and move closer to each other to clamp the round tubes. When multiple round tubes are clamped at the same time, the force on each round tube is uneven, which affects subsequent operations such as opening the cover.

The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0036] In this disclosure, the terms "upper," "lower," "inner," "middle," "outer," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for better description of the embodiments of this disclosure and their implementations, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to require them to be constructed and operated in a specific orientation. Furthermore, some of the aforementioned terms may be used to indicate other meanings besides orientation or positional relationship; for example, the term "upper" may in some cases indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in the embodiments of this disclosure according to the specific circumstances.

[0039] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0040] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0042] In some highly automated cell culture devices, operations such as opening and closing caps and pipetting of liquid bottles can be performed automatically. Automated operation of liquid bottles relies on accurate positioning and secure clamping.

[0043] To secure liquid bottles, a circular tube clamping mechanism is disclosed in related technologies. This mechanism includes a mounting base, multiple clamping members, multiple pressing members, and a drive module. Each clamping member is housed within the mounting base and has clamping holes for clamping the circular tube. One end of each pressing member is fixedly connected to the mounting base, and the other end of each pressing member contacts or abuts against the clamping member. The pressing members are used to adjust the clamping force of the clamping members. The drive module includes a drive mechanism and multiple drive blocks connected to the drive mechanism. The drive mechanism can drive each drive block to move, and each drive block cooperates with each pressing member to drive the clamping member to clamp the circular tube. The clamping members in the related technologies include a first clamping block and a second clamping block connected by a second elastic member. The drive module drives the pressing members to move, thereby compressing the second elastic member, so that the first and second clamping blocks approach each other and clamp the circular tube. The problem with the related technologies is that when the drive module moves the multiple drive blocks, the pressing members compress the second elastic member, causing the first and second clamping blocks to overcome the elastic force of the second elastic member and approach each other to clamp the circular tube. When multiple round tubes are clamped at the same time, the force on each tube is uneven, which affects subsequent operations such as opening the lid.

[0044] To ensure even force distribution on each liquid bottle when clamping multiple liquid bottles simultaneously, a combination of... Figure 1-7 As shown, this embodiment of the present disclosure provides a bottle clamping mechanism, which includes a first bottle clamping part 100, a supporting part 300, and a second bottle clamping part 200. The first bottle clamping part 100 is provided with a plurality of first clamping members 110, each with a first clamping groove 111. The supporting part 300 is provided with a plurality of bottle fixing positions 301 corresponding to the plurality of first clamping members 110. The second bottle clamping part 200 is movable relative to the first bottle clamping part 100 and is provided with a plurality of second clamping members 210, each with a second clamping groove 211. Multiple bottles are disposed at the plurality of bottle fixing positions 301. After 01, the second bottle clamping part 200 moves toward the first bottle clamping part 100, thereby simultaneously fixing multiple bottles through the first clamping member 110 and the second clamping member 210. The first clamping groove 111 and the second clamping groove 211 abut against the two side walls opposite to the bottle body. The first clamping member 110 or the second clamping member 210 includes a base part 260 and a floating part 270. The base part 260 remains fixed relative to the installation position. The floating part 270 is floatingly disposed on the base part 260 and in contact with the bottle body. After clamping the bottle body, the floating part 270 can be reset to move toward the base part 260 to achieve adaptive clamping.

[0045] The bottle clamping mechanism is used to clamp multiple liquid bottles simultaneously. Exemplarily, the liquid bottles can be closed bottles with caps, such as culture flasks or reagent bottles, or open bottles such as test tubes. In this embodiment, a culture flask is used as the liquid bottle, and the application scenario is described as fixing the culture flask before the automatic cap-opening mechanism opens it.

[0046] The bottle clamping mechanism includes a first bottle clamping part 100, a second bottle clamping part 200, and a support part 300. The support part 300 is provided with a bottle fixing position 301 for pre-fixing the culture bottle. For example, the support part 300 includes multiple bottle holders, which are hollow cylindrical in shape, and the culture bottle can be vertically placed into the bottle holder.

[0047] The second bottle clamping part 200 includes a plurality of first clamping members 110, and the first bottle clamping part 100 includes a plurality of second clamping members 210. The plurality of first clamping members 110 and the plurality of second clamping members 210 cooperate in a one-to-one correspondence. When clamping the liquid bottle, the second bottle clamping part 200 moves toward the first bottle clamping part 100, the first clamping groove 111 of the first clamping member 110 is in close contact with one side wall of the culture bottle, and the second clamping groove 211 of the second clamping member 210 is in close contact with the other side wall of the culture bottle. The first clamping members 110 and the second clamping members 210 together clamp the culture bottle to constrain the movement and rotation of the culture bottle.

[0048] The bottle clamping mechanism provided in this embodiment has a floating portion 270 in either the first clamping member 110 or the second clamping member 210. This embodiment uses the first clamping member 110 with the floating portion 270 as an example for explanation. Specifically, the first clamping member 110 includes a base portion 260 and a floating portion 270. The floating portion 270 is floatingly disposed on the base portion 260, meaning that the floating portion 270 can undergo a certain degree of resettable displacement relative to the base portion 260, thereby achieving adaptive adjustment of the clamping of the corresponding culture bottle.

[0049] The adaptive adjustment process of the floating part 270 includes a pre-positioning stage, an initial contact stage, a floating adjustment stage, and a stable clamping stage.

[0050] During the pre-positioning stage, multiple culture bottles are vertically placed into the bottle holder of the support part 300. The bottom of the bottle is restricted, and the sidewalls are in a clamping state. At this time, the first and second clamping members 210 are not in contact with the bottle. In the initial contact stage, the second bottle clamping part 200 drives the second clamping member 210 to move towards the first bottle clamping part 100. The second clamping groove 211 of the second clamping member 210 first contacts one sidewall of a portion of the bottle. Due to slight differences in bottle size or position, the contact time of different bottles may vary. In the floating adjustment stage, when a bottle is first contacted by the second clamping member 210, the bottle pushes the floating part 270 of the corresponding first clamping member 110. The floating part 270 moves towards the base, generating an initial clamping force. Subsequently, the second bottle clamping part 200 continues to move, and the second clamping members 210 that have not yet been in contact gradually contact other bottles, and the corresponding bottles push their respective floating parts 270. The compression amount of the floating part 270 of each bottle is determined by its own size and position. For example, a bottle with a slightly larger diameter will compress the floating part 270 more, while a bottle with a slightly smaller diameter will compress it less. During the stable clamping phase, the second bottle clamping part 200 moves to the preset end point of the stroke. At this time, all floating parts 270 are compressed to a balanced state by their corresponding bottles, and the elastic force of the elastic element is converted into clamping force. Because the compression amount of each floating part 270 is adapted to its respective bottle, the clamping force on each bottle ultimately matches its own needs, preventing displacement due to excessive looseness or deformation due to excessive tightness.

[0051] The bottle clamping mechanism provided in this embodiment features adaptive adjustment of the elasticity of the floating portion 270, with the clamping force directly determined by the reaction force of the bottle body on the floating portion 270. Even if multiple culture bottles differ, the compression of each floating portion 270 automatically compensates for the differences, ensuring that all culture bottles are within their own equilibrium range, thus guaranteeing the stability of subsequent operations such as capping and pipetting. Furthermore, the floating portion 270 can prevent bottle damage caused by rigid clamping, and its range of motion can accommodate culture bottles of a certain size range, reducing equipment adaptation costs.

[0052] Optionally, the floating portion 270 and the base portion 260 are connected by a return spring 280.

[0053] The return spring 280 is the core component that enables the floating part 270 to be reset and move. It has a simple structure and reliable operation.

[0054] Optionally, the spring constant of the return spring 280 gradually decreases as the compression stroke progresses.

[0055] The spring constant of the return spring 280 gradually decreases as the compression stroke progresses, further optimizing the adaptive clamping performance of the bottle clamping mechanism. This is particularly advantageous in scenarios where multiple bottles have significantly different sizes or where high-precision clamping force control is required. Specifically, when the floating part 270 first contacts the bottle, its spring constant is relatively large, allowing for the application of a large clamping force to the culture bottle with only a small movement of the first clamping member 110. In some cases, such as when the individual bottles vary significantly, the first clamping member 110 needs to continue moving a certain distance before contacting other culture bottles. During this process, the clamping force on the culture bottle that first contacts the floating part 270 does not increase significantly. However, once the first clamping member 110 contacts other culture bottles, it only needs to move a small distance to clamp the culture bottle.

[0056] Optionally, the return spring 280 includes a first spring and a second spring. During the process of the first clamping member 110 approaching the second clamping member 210, the first spring is compressed and the second spring is stretched. The elastic coefficient of the second spring increases with the increase of the stretching deformation.

[0057] During the deformation of the floating part 270, the second spring exerts opposite forces on the floating part 270 as the first spring. Specifically, the first spring pushes the floating part 270 outward to compress the liquid bottle. The second spring pulls the floating part 270 inward to reduce the force compressing the liquid bottle. As the elastic coefficient of the second spring gradually increases, the resultant force of the first and second springs increases slowly, but the rate of increase gradually decreases.

[0058] This configuration allows the floating part 270 to provide appropriate clamping force to the culture flask regardless of whether it moves a large or small distance.

[0059] Optionally, the return spring 280 includes a first spring and a magnet assembly, the magnet assembly including a first magnetic attraction portion and a second magnetic attraction portion disposed on the floating portion 270. As the floating portion 270 moves, the first magnetic attraction portion and the second magnetic attraction portion move closer together, increasing the attractive force. The compressive force on the first spring changes linearly. As the floating portion 270 moves, the attractive force provided by the magnet assembly can offset the increased compressive force of the spring, thereby allowing the floating portion 270 to provide a moderate clamping force to the culture flask whether it moves a large distance or a small distance.

[0060] Optionally, the second bottle clamping part 200 includes a mounting bracket 220, a synchronization bracket 230, and a drive mechanism 250, wherein the synchronization bracket 230 is slidably connected to the mounting bracket 220; the drive mechanism 250 is fixed to the mounting bracket 220 and drivenly connected to the synchronization bracket 230, and the drive mechanism 250 drives the synchronization bracket 230 to move toward or away from the first bottle clamping part 100.

[0061] Mounting bracket 220 serves as the basic support structure, fixed to a preset installation position or the main body of the equipment. Synchronization bracket 230 is slidably connected to mounting bracket 220 via linear guides or slider pairs, and is used to mount multiple first clamping parts 110. When the drive mechanism 250 drives the synchronization bracket 230 to move, it simultaneously moves multiple second bottle clamping parts 200 toward multiple first bottle clamping parts 100. This arrangement facilitates the simultaneous clamping of multiple culture bottles by the bottle clamping mechanism.

[0062] Optionally, the synchronization bracket 230 includes a sliding portion and a connecting portion, the sliding portion being connected to the mounting bracket 220, and the connecting portion being rotatably connected to the sliding portion.

[0063] For example, the connecting portion is connected to the sliding portion via a ball joint. When the diameters of multiple liquid bottles gradually decrease or increase, the multiple first clamping members 110 disposed on the connecting portion of the synchronization bracket 230 can be inclined close to the multiple second clamping members 210. This arrangement further improves the adaptability of the bottle clamping mechanism when clamping different bottles.

[0064] Optionally, the synchronization bracket 230 is slidably connected to the mounting bracket 220 via a linear track 240.

[0065] This configuration improves the synchronicity of the various positions when the synchronous support 230 slides, allowing the multiple second bottle clamping parts 200 to move more precisely and synchronously.

[0066] Optionally, the top surface of the second bottle clamping part 200 is provided with a bottle cap placement groove 264.

[0067] After the capping mechanism opens the cap, the cap of the culture flask can be placed into the corresponding placement groove. With this configuration, the capping mechanism can open multiple culture flasks consecutively, improving the capping efficiency.

[0068] Optionally, the second clamping member 210 includes a base portion 260 and a floating portion 270. The floating portion 270 is configured with a second clamping groove 211. The first bottle clamping portion 100 includes a mounting base 261, which has a sliding groove along the moving direction of the synchronous support 230. The floating portion 270 includes a chuck 271, a connecting rod 272, and a return spring 280. The chuck 271 is configured with the second clamping groove 211. The connecting rod 272 has its head connected to the chuck 271 and extends into the sliding groove. The return spring 280 is sleeved on the connecting rod 272. When the chuck 271 moves toward the mounting base 261, the return spring 280 is compressed.

[0069] Mounting base 261 is fixed to synchronous bracket 230, serving as the support base for floating part 270, and has a straight groove formed along the bottle clamping direction (i.e., the moving direction of synchronous bracket 230). The chuck 271 of floating part 270 is the component that directly contacts the bottle body, and has a second clamping groove 211 machined on its inner side. Exemplarily, the second clamping groove 211 is V-shaped or arc-shaped to adapt to the contour of the culture bottle. One end of connecting rod 272 is rigidly connected to chuck 271, and the other end extends into the groove of mounting base 261, restricting chuck 271 to move only along the groove direction. Return spring 280 is sleeved on connecting rod 272, with its two ends abutting against chuck 271 and mounting base 261 respectively, providing elastic return force.

[0070] In the initial state, the spring is at its initial length, and the clamp 271 protrudes from the mounting base 261. During clamping, the synchronous bracket 230 moves towards the first bottle clamping section 100 along with the drive mechanism 250, and the clamp 271 first contacts the side wall of the bottle; the reaction force of the bottle pushes the clamp 271 towards the mounting base 261, compressing the spring; the spring generates elastic force, which is the clamping force. During releasing, the drive mechanism 250 moves in the opposite direction, the pressure from the bottle on the clamp 271 disappears; the spring returns to its initial length, pushing the clamp 271 back to its initial position.

[0071] The base portion 260 and the floating portion 270 are located on the movable second clamping member 210, while the liquid bottle is pre-contacted or close to the immovable first clamping member 110 when placed on the support portion 300. This arrangement reduces the displacement of the liquid bottle during clamping. The chuck 271 is connected to the base portion 260 via a connecting rod 272, which helps maintain a relatively fixed clamping angle between the second clamping groove and the first clamping groove. The return spring 280 is sleeved on the connecting rod 272, which prevents the return spring 280 from twisting or bending during deformation and makes the return spring 280 easy to install.

[0072] Optionally, the mounting base 261 has multiple sliding grooves, and the floating part 270 is provided with multiple connecting rods 272 and multiple return springs 280.

[0073] The design of mounting base 261 with multiple sliding grooves and corresponding configuration of multiple connecting rods 272 and return springs 280 can improve the stability and force balance of floating part 270.

[0074] Optionally, the tail of the connecting rod 272 extends out from the slide groove, and the tail of the connecting rod 272 is threaded; the floating part 270 also includes a threaded adjustment member 274, which is disposed at the tail of the connecting rod 272 and abuts against the mounting base 261, and the effective length of the connecting rod 272 is adjusted by rotating the threaded adjustment member 274.

[0075] The threaded adjusting element 274 at the tail of the connecting rod 272 is designed to provide the bottle clamping mechanism with the ability to dynamically adjust the clamping force and initial position. The tail of the connecting rod 272 is machined with external threads, extending beyond the groove of the mounting base 261. The threaded adjusting element 274 is a nut, exemplarily a hexagonal nut or an adjusting knob with a handle, and it threadedly engages with the connecting rod 272. Rotating the threaded adjusting element 274 clockwise moves the nut toward the mounting base 261, increasing the effective length of the connecting rod 272 and increasing the extension of the chuck 271 relative to the mounting base 261; rotating it counterclockwise shortens the effective length of the connecting rod 272 and decreases the extension of the chuck 271. By changing the position of the threaded adjusting element 274, the initial compression and preload of the spring can be adjusted.

[0076] This configuration allows for adaptation to bottles of different diameters without the need to replace the chuck 271 or springs, simply by adjusting the threaded parts. Precise adjustment of the clamping force ensures that the capping torque requirement is matched to the clamping force.

[0077] Optionally, the thread at the tail of the connecting rod 272 is an external thread, and the thread adjusting member 274 includes a nut.

[0078] This configuration facilitates the adjustment of the effective length of the connecting rod 272.

[0079] Optionally, the tail of the connecting rod 272 is internally threaded, and the threaded adjustment member 274 includes an adjusting bolt that can be screwed into the internal thread.

[0080] With this configuration, the length of the tail of the connecting rod 272 extending from the slide is relatively short, the bottle clamping mechanism has a neater appearance on the threaded part, and it is less likely to interfere with other parts during movement.

[0081] Optionally, the slide includes a first section with a larger diameter and a second section with a smaller diameter, and the connection position of the first section and the second section forms an annular step 263, and the first end of the return spring 280 elastically presses against the annular step 263.

[0082] This design makes it easy to fix the return spring 280.

[0083] Optionally, the second end of the return spring 280 elastically presses against the collet 271.

[0084] This design simplifies the fixing method of the return spring 280 and facilitates the assembly of the bottle clamping mechanism.

[0085] Optionally, a retaining ring 273 is fixedly provided on the connecting rod 272, and the second end of the return spring 280 elastically presses against the retaining ring 273.

[0086] With this design, the spring can be concealed from the base portion 260, improving the aesthetics of the bottle clamping mechanism.

[0087] Optionally, the bottle clamping mechanism also includes a pressure sensor 400, which is located at the position where the first clamping member 110 contacts the bottle or the position where the second clamping member 210 contacts the bottle.

[0088] This configuration allows the bottle clamping mechanism to accurately control the pressure, reducing or preventing situations where excessive clamping force breaks the liquid bottle or insufficient clamping force fails to open the cap.

[0089] Optionally, the bottle clamping mechanism also includes a control unit configured to control the second clamping member 210 to stop moving when the pressure of the pressure sensor 400 is greater than a first preset pressure.

[0090] This prevents the first clamp 110 and the second clamp 210 from breaking the culture flask.

[0091] Optionally, the control unit is also configured to control the second clamping member 210 to continue moving until the pressure of the pressure sensor 400 is greater than the first preset pressure when the pressure of the pressure sensor 400 is less than the second preset pressure.

[0092] This ensures that the pressure applied to the culture flask meets the requirements of the cap-opening mechanism.

[0093] Optionally, the first bottle clamping part 100 includes a fixing plate 120, and a plurality of first clamping members 110 are disposed on the fixing plate 120; the bearing part 300 includes a bearing plate 310 and a cylindrical bottle holder 320, the bearing plate 310 being connected to the fixing plate 120; the cylindrical bottle holder 320 being disposed on the bearing plate 310.

[0094] Both the first clamping member 110 and the cylindrical bottle holder 320 are mounted on the fixing plate 120, which facilitates the pre-fixation of multiple liquid bottles by the bottle clamping mechanism. The pre-fixation of the liquid bottles by the cylindrical bottle holder 320 prevents them from tipping over.

[0095] Optionally, the cylindrical bottle holder 320 is provided with a heating device 330.

[0096] After the culture flask is placed into the cylindrical flask holder 320, the heating device 330 can still heat the culture flask to keep it at a suitable temperature. This configuration can reduce temperature changes in the culture flask during the opening and closing of the cap.

[0097] Optionally, the lower end of the first clamping member 110 contacts the top surface of the cylindrical bottle holder 320.

[0098] With this configuration, the cylindrical bottle holder 320 can be pre-positioned for installation using the first clamping member 110, which is beneficial for fixing the cylindrical bottle holder 320.

[0099] Optionally, the fixing plate 120 is arranged vertically, and a plurality of first clamping members 110 are disposed on the top surface of the fixing plate 120.

[0100] This arrangement is advantageous for fixing multiple first clamping members 110 in a straight line.

[0101] Optionally, the first clamping member 110 has a strip bolt hole.

[0102] This makes it easier to fine-tune the installation position of the first clamping component 110.

[0103] Optionally, the support plate 310 is connected to the side end face of the fixing plate 120.

[0104] The form in which the support plate 310 is fixed to the side end face of the fixing plate 120 makes it easy to adjust the height of the support plate 310 according to actual needs to adapt to liquid bottles of different heights.

[0105] Optionally, the floating part 270 and the base part are slidably connected by a mortise and tenon structure.

[0106] This configuration can reduce or avoid the difficulty in resetting the floating part 270 due to skewness.

[0107] Optionally, the inward-facing side of the first clamping groove and / or the second clamping groove is provided with a raised contact point.

[0108] This increases the frictional force that the clamping mechanism provides to the culture bottle after clamping it, preventing the culture bottle from rotating.
