Description

Technical Field

[0001] This utility model relates to the field of biopharmaceuticals, and in particular to a multi-channel capping device. Background Technology

[0002] As people's requirements for the quality, activity, and consistency of cell banks gradually increase, the traditional method of dispensing particulate suspensions using pipettes can no longer meet the industry's needs. Therefore, filling systems for particulate suspensions have emerged.

[0003] Existing filling systems for particulate suspensions include, for example, a cryopreservation tube filling machine and its operating method disclosed in Chinese Patent Publication No. CN115650141A. This machine includes an automatic cap-removing cryopreservation tube filling machine, comprising a cap-removing filling machine with an electrical control box and a track platform arranged parallel to the cap-removing filling machine. The track platform is equipped with a mold for placing packaging materials. Both the track platform and the cap-removing filling machine are controlled and connected to the electrical control box. The cap-removing filling machine, located between a loosening robotic arm and a tightening robotic arm, is also equipped with a filling needle holder for filling, which is telescopically driven on the cap-removing filling machine.

[0004] However, the filling machine disclosed in the above patent can only handle one frozen tube at a time, resulting in low filling efficiency and high energy consumption. In addition, during the capping process, the robotic arm has difficulty in accurately and quickly clamping the cap, requiring a lot of time for adjustment. Furthermore, this structure is also prone to problems such as not tightening or over-tightening due to inaccurate control. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model discloses a multi-channel capping device.

[0006] A multi-channel capping device includes a body, on which a test tube rack for placing containers is provided. Each container includes a body and a cap with a groove. The body is provided with a drive mechanism and a transmission mechanism connected to the drive mechanism. The transmission mechanism has an input shaft and multiple output shafts, and also includes a capping plate connected to the transmission mechanism.

[0007] The capping plate is detachably and movably connected to the machine body. The capping plate is provided with multiple capping parts, each of which corresponds to the output shaft of the transmission mechanism. Each capping part has a capping head whose shape matches the groove shape on the lid of the container.

[0008] Specifically, the capping plate has a structure with multiple capping heads combined with a transmission mechanism, which enables one drive mechanism to cap multiple containers simultaneously; the structure of the capping head coupled with the groove for force transmission can effectively reduce energy waste; in addition, since the capping plate is detachable from the body, a suitable capping head can be selected according to the shape of the groove on the cap and then the entire capping plate can be replaced, which has good practicality.

[0009] In addition, the transmission mechanism is usually a reduction gearbox.

[0010] Preferably, each of the capping components further includes a torque transmission head for connecting the output shaft and the capping head, the torque transmission head being movably connected to the capping plate via a bearing.

[0011] Specifically, the torque transmission head is used to transmit force between the output shaft and the capping head.

[0012] Preferably, the bearing includes a deep groove ball bearing and a thrust ball bearing.

[0013] Specifically, deep groove ball bearings can withstand larger radial forces transmitted from the torque transmission head, while thrust ball bearings can withstand larger axial forces transmitted from the torque transmission head. Together, they support the torque transmission head.

[0014] Preferably, the torque transmission head is hollow inside, and a first elastic device is provided inside the torque transmission head. The end of the first elastic device away from the capping head is fixed to the torque transmission head, and the torque transmission head is movably connected to the capping head.

[0015] Specifically, before capping, the capping head needs to be inserted into the groove on the cap body. When the groove is an irregular groove, the capping head often cannot be coupled with the irregular groove. In this case, the end of the capping head abuts against the top of the cap body, and the first elastic device is compressed. At this time, the drive mechanism is activated to rotate the capping head. When the capping head can be coupled with the irregular groove, the first elastic device will spring back and allow the capping head to be inserted into the irregular groove.

[0016] Preferably, the first elastic device includes a guide shaft and a first elastic element sleeved on the outside of the guide shaft. The capping head is sleeved with the guide shaft and can move along the axial direction of the guide shaft. The two ends of the first elastic element abut against the top of the capping head and the torque transmission head, respectively.

[0017] Specifically, this structure serves two purposes: firstly, it utilizes the elasticity of the first elastic element to automatically insert the capping head into the groove; secondly, it effectively protects the end of the capping head when it cannot be smoothly inserted into the groove, preventing damage from collision.

[0018] Preferably, it further includes a torque protection mechanism, which includes a connector for fixing to the torque transmission head and a second elastic device that meshes with the teeth of the connector, wherein one end of the second elastic device away from the capping member is movably connected to the output shaft.

[0019] The second elastic device includes a fixing member with a cavity and a second elastic body disposed in the cavity. The fixing member and the connecting member are toothed and engaged. The two ends of the second elastic body abut against the cavity wall and the output shaft, respectively.

[0020] Specifically, during the capping process, a cap jumping problem may occur (i.e., over-tightening causes the cap to jump from a tightened state to a loose state). The torque protection mechanism can effectively prevent this problem. When the cap is tightened, if you continue to drive it, since the cap is already tightened, you need to apply more torque to rotate it. However, the torque is not large enough at this time, and the torque transmission head and the connecting part will not rotate. The rotating fixed part will slide away from the connecting part along the teeth that mesh with the connecting part. At this time, the second elastic body is compressed. When the fixed part and the connecting part are completely separated, the fixed part and the connecting part will mesh again under the action of the rebound force of the second elastic body. This process is repeated, that is, there is continuous tooth jumping between the fixed part and the connecting part. In other words, the fixed part cannot drive the connecting part to rotate, and thus the cap cannot be tightened further.

[0021] Preferably, it also includes an electric cylinder for driving the capping plate to move towards the test tube rack. The capping plate is also provided with an elastic reset device. The elastic reset device includes a guide rod fixed to the capping plate. The guide rod is movably fixed to the machine body through a linear bearing. A third elastic element is sleeved on the guide rod. A stop is provided at the end of the guide rod away from the capping plate. The two ends of the third elastic element abut against the stop and the linear bearing, respectively.

[0022] Specifically, the electric actuator of the electric cylinder pushes the capping plate to move closer to the test tube rack. The capping plate, along with the guide rod, moves closer to the test tube rack. At this time, the distance between the stop and the linear bearing decreases, and the third elastic element is compressed. When the capping plate needs to be reset, the electric actuator first resets upward, and then, under the action of the rebound force of the third elastic element, the capping plate and the guide rod are reset.

[0023] Preferably, the cap plate is provided with a plurality of positioning holes and positioning edges, and the installation between the cap plate and the machine body is realized through the structure of the positioning holes and positioning edges.

[0024] Specifically, the machine body is equipped with matching connection holes and positioning protrusions at corresponding positions. The connection between the cap plate and the machine body is achieved by using bolts to connect the positioning holes and connection holes. The structure of the positioning edge and positioning protrusion assists in accurate positioning, ensuring that the cap plate can be quickly and accurately installed on the machine body, and that the cap plate, torque protection mechanism, and output shaft can all be properly aligned.

[0025] Preferably, the cap plate is provided with a plurality of reinforcing ribs for enhancing strength.

[0026] Compared with the prior art, the advantages of this utility model are:

[0027] The capping plate has a structure with multiple capping heads combined with a transmission mechanism, which enables one drive mechanism to cap multiple containers simultaneously. The structure of the capping head coupling with the groove for force transmission can effectively reduce energy waste. In addition, since the capping plate is detachable from the body, a suitable capping head can be selected according to the shape of the groove on the cap, and then the entire capping plate can be replaced, which has good practicality.

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1-7 As shown, the multi-channel capping device includes a body 10, a test tube rack 20 for placing a container 21 on the body 10, the container 21 includes a body and a cap with a groove, the body 10 is provided with a drive mechanism and a transmission mechanism 30 connected to the drive mechanism, the transmission mechanism 30 is provided with an input shaft and multiple output shafts, and also includes a capping plate 40 connected to the transmission mechanism 30.

[0037] The capping plate 40 is detachably and movably connected to the body 10. The capping plate 40 is provided with multiple capping parts, and each capping part corresponds to the output shaft of the transmission mechanism 30. Each capping part is provided with a capping head 41 whose shape is adapted to the groove shape on the lid of the container 21.

[0038] The capping plate 40 is equipped with multiple capping heads 41 combined with the transmission mechanism 30, which enables one drive mechanism to simultaneously cap multiple containers 21. The structure of the capping head 41 coupled with the groove for force transmission can effectively reduce energy waste. In addition, since the capping plate 40 is detachable from the body 10, a suitable capping head 41 can be selected according to the shape of the groove on the cap, and then the capping plate 40 can be replaced as a whole, which has good practicality.

[0039] In addition, the transmission mechanism 30 is usually a reduction gearbox.

[0040] Each capping component also includes a torque transmission head 42 for connecting the output shaft and the capping head 41. The torque transmission head 42 is movably connected to the capping plate 40 via a bearing 43.

[0041] The torque transmission head 42 enables the transmission of force between the output shaft and the capping head 41.

[0042] Bearing 43 includes deep groove ball bearings and thrust ball bearings.

[0043] Deep groove ball bearings can withstand large radial forces transmitted from torque transmission head 42, while thrust ball bearings can withstand large axial forces transmitted from torque transmission head 42. Both of them serve to support torque transmission head 42.

[0044] The torque transmission head 42 is hollow inside, and a first elastic device is provided inside the torque transmission head 42. The end of the first elastic device away from the capping head 41 is fixed to the torque transmission head 42, and the torque transmission head 42 and the capping head 41 are movably connected.

[0045] Before capping, the capping head 41 needs to be inserted into the groove on the cap body. When the groove is an irregular groove, the capping head 41 often cannot be coupled with the irregular groove. In this case, the end of the capping head 41 abuts against the top of the cap body, and the first elastic device is compressed. At this time, the drive mechanism is activated to rotate the capping head 41. When the capping head 41 can be coupled with the irregular groove, the first elastic device will rebound and allow the capping head 41 to be inserted into the irregular groove.

[0046] The first elastic device includes a guide shaft 51 and a first elastic element 52 sleeved on the outside of the guide shaft 51. The capping head 41 is sleeved with the guide shaft 51 and can move along the axial direction of the guide shaft 51. The two ends of the first elastic element 52 abut against the capping head 41 and the torque transmission head 42, respectively.

[0047] This structure serves two purposes: firstly, it allows the first elastic element 52 to automatically insert the capping head 41 into the groove; secondly, it effectively protects the end of the capping head 41 from damage due to collision when the capping head 41 cannot be inserted smoothly into the groove.

[0048] It also includes a torque protection mechanism 60, which includes a connector 61 for fixing to the torque transmission head 42, and a second elastic device that meshes with the connector 61 in a toothed manner. The end of the second elastic device away from the cap is movably connected to the output shaft.

[0049] The second elastic device includes a fixing member 62 with a cavity and a second elastic body 63 disposed in the cavity. The fixing member 62 engages with the connecting member 61 in a toothed manner, and the two ends of the second elastic body 63 abut against the cavity wall and the output shaft, respectively.

[0050] Specifically, during the capping process, a cap jumping problem may occur (i.e., over-tightening causes the cap to jump from a tightened state to a loose state). The torque protection mechanism 60 can effectively prevent this problem. When the cap is tightened, if you continue to drive it, since the cap is already tightened, you need to apply more torque to rotate it. However, the torque is not large enough at this time, and the torque transmission head 42 and the connecting member 61 will not rotate. Instead, the rotating fixing member 62 will slide away from the connecting member 61 along the tooth profile that meshes with the connecting member 61. At this time, the second elastic body 63 is compressed. When the fixing member 62 and the connecting member 61 are completely separated, the fixing member 62 and the connecting member 61 will mesh again under the action of the rebound force of the second elastic body 63. This process is repeated, that is, there is continuous tooth jumping between the fixing member 62 and the connecting member 61. In other words, the fixing member 62 cannot drive the connecting member 61 to rotate, and thus the cap cannot be tightened further.

[0051] It also includes an electric cylinder 73 for driving the capping plate 40 to move toward the test tube rack 20. The capping plate 40 is also provided with an elastic reset device. The elastic reset device includes a guide rod 71 fixed to the capping plate 40. The guide rod 71 is movably fixed to the machine body 10 through a linear bearing 74. A third elastic element 72 is sleeved on the guide rod 71. A stop is provided at the end of the guide rod 71 away from the capping plate 40. The two ends of the third elastic element 72 abut against the stop and the linear bearing 74, respectively.

[0052] The electric actuator of the electric cylinder 73 pushes the capping plate 40 to move closer to the test tube rack 20. The capping plate 40, along with the guide rod 71, moves closer to the test tube rack 20. At this time, the distance between the stop and the linear bearing 74 is reduced, and the third elastic element 72 is compressed. When the capping plate 40 needs to be reset, the electric actuator first resets upward, and then, under the action of the rebound force of the third elastic element 72, the capping plate 40 and the guide rod 71 are reset.

[0053] The cap plate 40 is provided with a plurality of positioning holes 81 and positioning edges 82, and the installation between the cap plate 40 and the body 10 is realized through the structure of the positioning holes 81 and positioning edges 82.

[0054] The corresponding position of the body 10 is provided with matching connection holes and positioning protrusions. The connection between the cover plate 40 and the body 10 is realized by bolt connecting the positioning hole 81 and the connection hole. The structure of the positioning edge 82 and the positioning protrusion assists in accurate positioning, ensuring that the cover plate 40 can be quickly and accurately installed on the body 10, and that the cover part, torque protection mechanism 60 and output shaft can all be properly aligned.

[0055] The cap plate 40 is provided with several reinforcing ribs 83 for strengthening.
