Description

Technical Field

[0001] This utility model relates to the field of automated in vitro diagnostic equipment, specifically to a tube cover limiting block and a tube body clamp for tube body opening and closing cover. Background Technology

[0002] With the development of sample analysis technologies such as bioassay and in vitro diagnostics, sample processing has become increasingly complex. This necessitates the transfer of individual or multiple tubes, and the opening and closing of tube caps to enable detection and other tasks. For example, in the preservation and use of cryovials, it is frequently necessary to transfer and detect the bacterial cultures within the cryovials.

[0003] However, existing technologies cannot individually control any one or more of the cryovials with holes and perform opening and closing actions on the retrieved cryovials. For example, the cryovial capping machine disclosed in CN219363219U uses multiple capping motors and drive shafts to drive capping bits to rotate and open / close the cryovials with holes, and then pushes the cap out through an internal push rod. However, the above capping machine is not only complex in overall structure, but more importantly, it can only open and close all the cryovials with holes simultaneously, and cannot individually control any one of the cryovials with holes. Furthermore, after the cryovial is opened, the cap remains on the capping bit, making it impossible to use the capping bit to perform capping actions on other cryovials.

[0004] To address the aforementioned problem of not being able to perform the opening and closing action on individual cryopreservation tubes, utility model patent application CN111392673A protects an automatic tube opening and closing device. This device uses tube wall grippers to hold the tube wall, followed by a three-axis electric gripper to clamp the cap, which is then opened under the drive of a rotary motor. While this automatic tube opening and closing device can open and close the cap on a single tube, it suffers from low efficiency, handling only one tube at a time and unable to simultaneously open and close multiple tubes, severely impacting worker efficiency. Furthermore, most existing cap storage positions are recessed or sunken, resulting in a small exposed cap area, making it difficult for mechanical grippers to hold the cap securely. Additionally, existing cap storage positions with protruding structures lack guiding and precise positioning functions, potentially failing to accurately place the cap in the designated position when used with low-precision robotic arms, thus affecting subsequent operations. In summary, those skilled in the art urgently need a new cap-opening device that can perform cap-opening and cap-closing actions on one or more specific pipes as needed through a cap-opening and cap-closing control system, thereby improving the stability of the pipes and caps, and thus improving the work efficiency of the staff and the reliability of the system. Utility Model Content

[0033] The technical solution of this utility model has the following advantages:

[0034] 1. The present invention provides a pipe clamp for opening and closing a pipe cover, wherein the temporary storage position for the pipe cover is a pipe cover limiting block disposed on the limiting plate; the pipe cover limiting block includes one or more of the following structures: a bottom surface of the limiting block abutting against the bottom surface of the pipe cover, an inner protrusion of the limiting block abutting against the inner wall of the pipe cover, and an outer protrusion of the limiting block corresponding to the outer peripheral wall of the pipe cover for placing, guiding and limiting the pipe cover.

[0035] In this invention, by providing an inner protrusion on the cap limiting block, the inner side of the cap can be limited, effectively preventing misalignment or eccentricity when the cap is placed after opening. By providing an outer protrusion on the cap limiting block, the cap can be effectively guided during placement, allowing the rotating gripper to accurately place the cap into the limiting block. Simultaneously, the outer protrusion also provides a limiting and fixing effect on the outer side of the cap.

[0036] 2. The tube clamp for tube body opening and closing cover provided by this utility model has at least two outer protrusions of the limiting blocks, and the adjacent outer protrusions of the limiting blocks form a gripping gap to avoid the movement stroke of the rotating jaws when they open or clamp.

[0037] In this invention, there are at least two protruding limiting blocks. The adjacent protruding limiting blocks form a gripping gap to avoid the opening or clamping stroke of the rotating gripper. This gripping gap allows the rotating gripper to easily grip the outer wall of the tube cap.

[0038] 3. The pipe clamp for opening and closing a pipe cover provided by this utility model includes a temporary storage position for the pipe cover, which is a limiting protrusion provided on the limiting plate; the opening edge of the pipe cover is engaged with the limiting protrusion to limit and fix the pipe cover. The limiting protrusion can be directly machined on the limiting plate, which is simple and reliable in structure, easy to process, and can also firmly and reliably position and fix the pipe cover.

[0039] 4. The tube clamp for opening and closing a tube cover provided by this utility model includes:

[0040] A tube support assembly, wherein the tube support assembly is provided with at least one cavity for accommodating the tube body, and the tube support assembly is also provided with a tube cap storage position for storing the tube cap.

[0041] A tube fixing assembly is driven to be connected to the tube body to prevent the tube body from rotating in its circumferential direction;

[0042] Mounting base, the tube body support assembly and the tube body fixing assembly are mounted on the mounting base;

[0043] A rotating gripper is driven to clamp and rotate the tube cap to complete the opening and closing action of the tube cap on the tube body. During operation, any one of the rotating grippers can be adapted to the opening and closing action of multiple tube caps and place the corresponding tube cap in the tube cap storage position.

[0044] To address the problem that existing tube cap opening and closing technologies can only perform the opening and closing action on one specific tube at a time, failing to achieve the same action on multiple tubes with a single device, resulting in low efficiency and reduced work productivity, this invention first establishes a tube support assembly. This assembly has multiple cavities for accommodating tubes, allowing operators to transfer one or more tubes from a centralized tube storage box to the support assembly as needed. Then, a tube fixing assembly positions and secures the tubes to prevent rotation along their circumferential direction. Furthermore, during this process, a cap storage area on the tube support assembly effectively stores caps opened by the rotating gripper, freeing up the gripper to handle the next cap. This structure efficiently and easily stores caps while freeing the gripper. This structure achieves the opening and closing of multiple specific tubes using a single rotating gripper. The structure is simple and reliable, effectively solving the problem of existing technologies being unable to simultaneously perform opening and closing of multiple specific tubes. In addition, the aforementioned pipe support assembly and pipe fixing assembly are mounted on the mounting base, thereby forming an integral structure of the pipe support assembly and pipe fixing assembly, improving the degree of equipment integration, and facilitating the installation and use of the pipe clamps used for the pipe opening and closing cover.

[0045] 5. The pipe clamp for opening and closing a pipe cover provided by this utility model, wherein the pipe support assembly includes:

[0046] A support frame, which abuts against the bottom surface of the tube to support the tube;

[0047] A limiting plate is provided with a limiting hole that matches the tube body to limit the position of the tube body.

[0048] In this invention, the support frame abuts against the bottom surface of the tube, effectively supporting multiple tubes. Simultaneously, the limiting hole on the limiting plate effectively limits the position of the tube body. The support frame and the limiting plate form a cavity for accommodating the tube, keeping it upright.

[0049] 6. The tube clamp for opening and closing the tube cover provided by this utility model has a support frame that is a bent structure with a different distance from the limiting plate, so as to adapt to the tubes of different heights.

[0050] In this invention, the support frame with the aforementioned bending structure can effectively change the distance between the support frame and the limiting plate, thereby allowing the tube clamp for the tube opening and closing cap to adapt to tubes of different heights. When storing cryopreservation tubes using the aforementioned support frame, different models of cryopreservation tubes, such as 0.5ml cryopreservation tubes, 1ml cryopreservation tubes, and 2ml cryopreservation tubes, can be supported by the support frames of different heights.

[0051] 7. The tube clamp for tube opening and closing cover provided by this utility model, wherein a plurality of tubes are arranged in a straight line on the limiting plate through the limiting holes; and the support frame is arranged along the arrangement direction of the plurality of tubes.

[0052] In this invention, multiple tubes are arranged in a straight line on the limiting plate, which allows the tube fixing component to securely and reliably fix multiple tubes at the same time through the straight tube clamps, effectively reducing the positioning difficulty when the tube fixing component positions multiple tubes at the same time.

[0053] 8. The tube clamp for tube opening and closing cover provided by this utility model, wherein the support frame is a planar structure disposed below the limiting plate, and the outer contour edge of the planar structure sequentially supports each tube on the tube support assembly; both ends of the support frame are also provided with bent ends for restricting the tube from sliding out of the support frame.

[0054] In this invention, the support frame is configured as a support plate structure to support the tube body. Furthermore, bent ends are provided at both ends of the support frame to restrict the sliding movement of the tube body. This structure occupies little space and can effectively cooperate with the limiting plate to achieve spatial positioning of the tube body.

[0055] 9. The present invention provides a pipe clamp for opening and closing pipe covers, wherein the pipe cover temporary storage position is disposed on the limiting plate, adjacent to the pipe body. In the present invention, by setting the pipe cover temporary storage position on the limiting plate, the travel distance of the rotating gripper can be effectively reduced, thereby improving the working efficiency of the pipe clamp for opening and closing pipe covers.

[0056] 10. The tube clamp for opening and closing a tube cover provided by this utility model, wherein the tube fixing assembly includes:

[0057] The tube body clamps are at least one and are arranged symmetrically on both sides of the tube body arrangement direction, and are also arranged along multiple tube body arrangement directions. The symmetrically arranged tube body clamps have a clamping state in which they move towards each other under drive to synchronously clamp and fix each tube body, and a releasing state in which they move away from each other under drive to synchronously release each tube body.

[0058] The gripper drive mechanism includes: a gripper drive source and two drive sliders that move towards or away from each other under the drive of the gripper drive source; the two drive sliders are respectively fixedly connected to the two tube grippers to drive the tube grippers to clamp and release.

[0059] In this invention, multiple tubes are clamped and fixed by parallel and symmetrically arranged tube clamps. These tube clamps provide a stable and reliable simultaneous clamping and fixing of multiple tubes, effectively fulfilling the requirement for simultaneous fixation of multiple tubes. Furthermore, when the limiting holes on the limiting plate are arranged in a straight line, multiple tubes can be stably and reliably fixed simultaneously by a single straight-plate-shaped tube clamp.

[0060] 11. The tube clamp for tube body opening and closing cover provided by this utility model, wherein the support frame is provided with a protrusion extending toward the limiting plate;

[0061] The gripper drive source and the drive slider are disposed in the cavity formed by the protrusion; the tube gripper is arranged parallel to the support frame to clamp and fix the tube on the support frame;

[0062] The protrusion facing the limiting plate is adapted to abut against the bottom of the tube.

[0063] At the same time, the tube clamps adapted to the drive slider are parallel to each other with the support frame, so as to firmly and reliably clamp and fix multiple tubes while realizing the miniaturization of the equipment.

[0064] 12. The tube clamp for opening and closing a tube body cover provided by this utility model includes: a clamp block mounted on the drive slider, and a clamp elastic member fixed on the clamp block; the clamp block is a rigid strip structure, and the clamp elastic member is disposed on the side of the clamp block facing the tube body.

[0065] In this invention, the cooperation between the aforementioned gripper blocks and the gripper elastic elements allows for better positioning and fixation of the tube body. The gripper blocks possess sufficient hardness to ensure that the gripper elastic elements deform within a preset range. Furthermore, the gripper elastic elements provide sufficient elastic deformation, allowing the grippers to clamp the tube body tightly. Of course, in this invention, the aforementioned gripper blocks and / or gripper elastic elements can be selected according to the mechanical strength requirements of the tube body, independently clamping and fixing the tube body.

[0066] 13. The tube clamp for opening and closing a tube cover provided by this utility model includes: a clamp block and / or a clamp elastic element; the clamp block or the clamp elastic element is mounted on the drive slider; the clamp block is provided with a groove that is adapted to the shape of the tube body.

[0067] 14. The pipe clamp for pipe body opening and closing cover provided by this utility model, wherein the mounting base includes:

[0068] Mounting base is provided on one of the opposite sides of the tube support assembly, and the support frame and / or the limiting plate are fixed on the mounting base;

[0069] A side mounting plate is disposed on another set of opposite sides of the tube support assembly, and the two ends of the side mounting plate in the length direction are fixedly connected to the mounting base; the gripper drive source is fixed on the side mounting plate.

[0070] In this utility model, one or both of the support frame and the limiting plate can be fixed to the mounting base as needed.

[0071] 15. The method of using the tube clamp for the tube body opening and closing cover provided by this utility model includes the following steps:

[0072] Step S1: The rotating gripper grabs one or more tubes as needed and sequentially transfers the tubes into the cavity formed by the limiting hole of the limiting plate and the support structure.

[0073] In step S2, the tube fixing assembly is driven to clamp and fix the tube on the limiting plate to prevent the tube from rotating in its circumferential direction.

[0074] Step S3: The rotating gripper sequentially performs the opening action on the cap of each tube on the limiting plate, and places the cap one by one in the cap storage position to complete the opening action; during the opening process, the rotating gripper holds the cap and rotates upward under drive.

[0075] Step S4, the tube fixing assembly maintains the clamping and fixing of the tube body;

[0076] The rotating gripper sequentially removes the tube caps from the tube cap storage position and performs a closing action on each tube body on the limiting plate to complete the closing action; during the closing process, the rotating gripper holds the tube cap and rotates and descends under drive;

[0077] In step S5, the tube fixing assembly is driven to release the tube on the limiting plate; the rotating gripper grasps the tube and moves it to the initial position.

[0078] In this invention, the pipe clamp for opening and closing the pipe cover, in conjunction with the above-described method, enables the opening and closing of multiple specific pipes through a set of rotating grippers. This effectively solves the problem in the prior art where the pipe cover opening and closing mechanism can only perform the opening and closing action on one specific pipe as needed, and cannot perform the opening and closing action on multiple specific pipes through a single device, resulting in low efficiency and reduced work efficiency.

[0091] Example 1

[0092] See Figure 6 , Figure 6 A three-dimensional structural diagram of a tube cap limiting block provided in an embodiment of this utility model is shown. In this embodiment, the tube cap limiting block 8 includes: a limiting block bottom surface 801 that abuts against the bottom surface of the tube cap 2, and a limiting block inner protrusion 802 that abuts against the inner wall of the tube cap 2. The limiting block bottom surface 801 serves to support the bottom surface of the tube cap 2 and keep it horizontal. Simultaneously, it prevents residual reagents on the tube cap 2 from directly contacting the equipment; subsequent cleaning only requires cleaning the limiting block bottom surface 801, making cleaning convenient. Furthermore, the limiting block inner protrusion 802 engages with the inner cavity of the tube cap 2, thereby limiting and fixing the tube cap 2 from its inner edge and preventing positional displacement. Optionally, the outer contour edge of the limiting block inner protrusion 802 is also provided with a chamfer to guide the tube cap 2 into the limiting block inner protrusion 802.

[0093] In a preferred embodiment, the pipe cap limiting block 8 further includes: a limiting block outer protrusion 803 corresponding to the outer peripheral wall of the pipe cap 2 for placing, guiding and limiting the pipe cap 2; and the limiting block outer protrusion 803 is at least two pieces, and the adjacent limiting block outer protrusions 803 form a gripping gap to avoid the movement stroke of the rotating gripper when it opens or clamps.

[0094] For example, the outer protrusion 803 of the limiting block can be three pieces, and the adjacent outer protrusions 803 of the limiting block form a gripping gap to avoid the movement stroke of the rotating gripper when it opens or clamps.

[0095] In a preferred embodiment, the outer protrusion 803 of the limiting block has a trapezoidal structure, a guide surface for guiding the tube cap 2, and an arc-shaped limiting surface adapted to the shape of the tube cap 2.

[0096] The aforementioned arc-shaped limiting surface is adapted to the outer contour shape of the pipe cap 2, thereby more firmly and reliably limiting and fixing the pipe cap 2. Specifically, the outer protrusion 803 of the limiting block is connected to the outer peripheral wall of the pipe cap 2, limiting and fixing the pipe cap 2 from its outer edge. Optionally, the outer protrusion 803 of the limiting block can be a trapezoidal structure of the pipe cap 2, with its inclined surface facing the pipe cap 2. The trapezoidal outer protrusion 803 guides the pipe cap 2 to be inserted more accurately into the inner protrusion 802 of the limiting block.

[0097] See Example 2 Figure 1 and Figure 2 , Figure 1 The diagram shows a first-view perspective perspective view of the combined structure of the tube support component and the tube fixing component in an embodiment of the present invention. Figure 2 This is a second-view perspective perspective view of the combined structure of the tube support component and the tube fixing component in an embodiment of the present invention.

[0098] The tube clamp for opening and closing the tube cover provided in this embodiment includes:

[0099] A tube support assembly, wherein the tube support assembly is provided with at least one cavity for accommodating the tube 1;

[0100] A tube fixing assembly is driven to be connected to the tube body 1 to prevent the tube body 1 from rotating in its circumferential direction;

[0101] Mounting base 3, on which the tube support assembly and the tube fixing assembly are mounted; specifically, the mounting base 3 makes it easier to replace the tube support assembly and the tube fixing assembly. When the above components need to be replaced, simply remove the mounting base 3 which integrates the tube support assembly and the tube fixing assembly.

[0102] A rotating gripper is driven to clamp the tube cap 2 and rotate it to complete the opening and closing action of the tube cap 2 on the tube body 1; during operation, any one of the rotating grippers is adapted to the opening and closing action of multiple tube caps 2 on the tube body 1.

[0103] In one specific embodiment, the rotating gripper is positioned above the tube support assembly and the tube fixing assembly. It can move horizontally and vertically via a drive mechanism such as a motor, push rod, or pneumatic device. The rotating gripper has an actuator facing the tube cap 2 capable of rotating to open and gripping the tube cap 2. After the tube cap 2 is unscrewed, the drive mechanism moves the actuator holding the tube cap 2 to a designated position, and then the actuator releases the tube cap 2, temporarily storing it in the designated position. In one example, the actuator is a gripper-type actuator that grips both sides of the tube cap 2 for rotating opening. In another example, the actuator is a columnar body directly abutting the upper surface of the tube cap 2, forming a connection with the tube cap 2 through snap-fit, magnetic attraction, or adhesion, and then rotating to unscrew the tube cap 2 from the tube body 1. It is understood that this embodiment does not limit the opening principle of the actuator selected for the rotating gripper; any actuator capable of unscrewing and gripping or engaging the tube cap 2 can be used.

[0104] In this embodiment, the tube support assembly includes a limiting plate 5, which has limiting holes 6 adapted to the tube body 1 to limit the position of the tube body 1. In an optional embodiment, multiple tube bodies 1 are arranged in a straight line on the limiting plate 5 through the limiting holes 6; and the support frame 4 is arranged along the arrangement direction of the multiple tube bodies 1. It is understood that the above embodiments do not specifically limit the arrangement of the multiple limiting holes 6. In other embodiments, the multiple limiting holes 6 can also be arranged in an L-shape, Z-shape, or other shapes.

[0105] In an optional embodiment, for the tube body 1 having an outer flange, the outer flange of the tube body 1 can be fixed by engaging the limiting hole 6. In a preferred embodiment, the tube body support assembly further includes a support frame 4, which abuts against the bottom surface of the tube body 1 to support the tube body 1; the support frame 4 has multiple bent structures with different spacing from the limiting plate 5, and the bent structures form a groove 19, which accommodates tube bodies 1 of different heights. Specifically, refer to... Figure 4 For pipes 1 of different specifications, grooves 19 of varying depths can be formed through a bending structure, allowing pipes 1 of different specifications to be accommodated within the grooves 19. Further, as... Figure 7As shown, the outer contour edge of the groove 19 formed by the support frame 4 sequentially supports each tube 1 on the tube support assembly; both ends of the support frame 4 are also provided with bent ends 17 for preventing the tube 1 from sliding out of the support frame 4. Specifically, during the process of inserting the tube 1 into the limiting hole 6, it may not be able to be completely vertical. If there is no protection or limiting structure, the tube 1 may slide directly out of the support frame 4, resulting in sample loss. Therefore, by providing bent ends 17 on the support frame 4, it is possible to prevent the tube 1 from sliding out of the support frame 4 during the process of inserting the tube 1 into the limiting hole 6.

[0106] In a preferred embodiment, the support frame 4 is a flat, plate-like structure to support the bottom of the tube 1, thereby meeting the storage requirements of tubes 1 at a single height. In an alternative embodiment, the support frame 4 has a supporting plane facing the tube 1; for example, the support frame 4 may be a disc-shaped device with a tray or similar device on top.

[0107] In this embodiment, refer to Figure 3 An exploded view of the combined structure of the pipe support assembly and the pipe fixing assembly in an embodiment of the present invention is shown. The mounting base 3 further includes a mounting base 7, which is disposed on one of a set of opposite sides of the pipe support assembly and is used to fix the pipe support assembly; the support frame 4 and / or the limiting plate 5 are fixed on the mounting base 7.

[0108] Optionally, a side mounting plate 9 for fixing the pipe fixing assembly is provided on another set of opposite sides of the pipe support assembly; both ends of the side mounting plate 9 in the length direction are connected to the mounting base 7. This side mounting plate 9 improves the stability of the mounting base 3, thereby preventing movement of components during system operation and thus preventing malfunctions. The gripper drive source 11 is fixed to the side mounting plate 9. The support frame 4 and the side mounting plate 9 are detachable separate structures, installed and fixed on the mounting base 7 to allow for quick replacement of support frames 4 of different specifications.

[0109] Furthermore, the aforementioned side mounting plate 9 consists of two symmetrically arranged rectangular plates. On one of the opposing sides of the tube support assembly, a mounting base 7 for fixing the tube support assembly is provided; this mounting base 7 consists of two rectangular upright plates. In this embodiment, the gripper drive source 11 for driving the tube fixing assembly is mounted on the aforementioned side mounting plate 9. In an optional embodiment, the aforementioned side mounting plate 9 and support frame 4 are detachable structures to facilitate the production and installation of components. This embodiment does not specifically limit whether the mounting base 7 and side mounting plate 9 are detachable structures; in other embodiments, the mounting base 7 and side mounting plate 9 can also be an integral structure to reduce the installation difficulty of the cover opening device.

[0110] In an optional embodiment, the support frame 4 and the side mounting plate 9 are an integral structure and are fixed on the mounting base 7.

[0111] In an optional embodiment, a mounting base 7 for fixing the tube support assembly is provided on one of a set of opposite sides of the tube support assembly; the support frame 4 is fixed on the mounting base 7, and the limiting plate 5 is mounted on another independent base above the support frame 4.

[0112] Furthermore, such as Figure 3 As shown, the tube fixing assembly includes:

[0113] The tube body clamps 10 are at least two, arranged in parallel and symmetrically on both sides of the tube body 1 arrangement direction, and arranged along multiple tube body 1 arrangement directions; the two tube body clamps 10 have a clamping state in which they move towards each other under drive to synchronously clamp and fix each tube body 1, and a releasing state in which they move away from each other under drive to synchronously release each tube body 1.

[0114] The tube body gripper drive mechanism includes: a gripper drive source 11 and two drive sliders 12 that move towards or away from each other under the drive of the gripper drive source 11; the two drive sliders 12 are respectively fixedly connected to two tube body grippers 10 to drive the tube body grippers 10 to clamp and release the tube body 1. The gripper drive source 11 can be a motor, pneumatic device, or push rod, etc., which transmits the driving force to the tube body grippers 10 through the drive sliders 12. The movement trajectory of the drive sliders 12 can be either linear or arc-shaped, and any form that can cause movement towards or away from the tube body 1 can be selected.

[0115] Furthermore, the support frame 4 is provided with a protrusion 16 extending toward the limiting plate 5. The aforementioned gripper drive source 11 and the drive slider 12 are slidably disposed within the cavity formed by the protrusion 16; the above structure allows the tube gripper 10 to be arranged parallel to the support frame 4, with the protrusion 16 facing the limiting plate 5, thereby generating space for accommodating the gripper drive source 11 and the drive slider 12.

[0116] Furthermore, such as Figure 3 As shown, the tube body gripper 10 includes: a gripper block 13 mounted on the drive slider 12, and a gripper elastic member 14 fixed on the gripper block 13; the gripper block 13 is a rigid strip structure, and the gripper elastic member 14 is disposed on the side of the gripper block 13 facing the tube body 1.

[0117] The interaction between the aforementioned gripper block 13 and gripper elastic element 14 allows for better positioning and fixation of the tube body 1. The gripper block 13 possesses sufficient hardness to ensure that the gripper elastic element 14 deforms within a preset range. Furthermore, the gripper elastic element 14 provides sufficient elastic deformation, allowing the tube body gripper 10 to clamp the tube body 1. As an example, the gripper block 13 is provided with an insertion hole, and the drive slider 12 is provided with a protrusion adapted to the insertion hole. The protrusion is inserted into the insertion hole, and the gripper block 13 is fixed to the drive slider 12 by screws.

[0118] In another embodiment, the tube body gripper 10 includes: a gripper block 13 or a gripper elastic member 14; the gripper block 13 or the gripper elastic member 14 is mounted on the drive slider 12; the gripper block 13 or the gripper elastic member 14 is provided with a groove adapted to the shape of the tube body 1.

[0119] Understandably, the above embodiments do not specifically limit the structure of the tube clamp 10. For example, the tube clamp 10 may only include: a clamp block 13 mounted on the drive slider 12, the clamp block 13 having a groove adapted to the shape of the tube body 1. Alternatively, the tube clamp 10 may only include: a clamp elastic element 14 mounted on the drive slider 12. In this embodiment, the clamp block 13 or the clamp elastic element 14 can be selected as needed to independently clamp and fix the tube body 1. That is, if the strength of the tube body 1 allows, the tube clamp 10 directly clamps the tube body 1 through the rigid clamp block 13 to reduce the complexity of the structure; on the other hand, if the strength of the tube body 1 is low and cannot withstand a large clamping force, the tube clamp 10 can clamp the tube body 1 through the clamp elastic element 14.

[0120] In any of the above embodiments, the gripper block 13 or the gripper elastic element 14 may be provided with a groove structure that is adapted to the shape of the tube body 1, or any structure adapted to the tube body 1, including: trapezoidal, semi-circular, wavy, etc.

[0121] In this embodiment, as Figure 5 and Figure 6 As shown, the pipe support assembly is also provided with a pipe cap temporary storage position 18 for storing the pipe cap 2. The pipe cap temporary storage position 18 is a pipe cap limiting block 8 provided on the pipe support assembly; the pipe cap limiting block 8 is the pipe cap limiting block in Embodiment 1, which has been described in detail above and will not be repeated here.

[0122] Understandably, the above embodiments do not specifically limit the connection method between the pipe cap limiting block 8 and the limiting plate 5. In one optional embodiment, the pipe cap temporary storage position 18 is a pipe cap limiting block 8 integrally formed on the limiting plate 5. The integral forming of the pipe cap limiting block 8 on the limiting plate 5 can effectively ensure that the pipe cap limiting block 8 will not be offset relative to the limiting plate 5, ensuring that the rotating gripper can stably and reliably grasp the pipe cap 2 with each action. In another optional embodiment, the pipe cap limiting block 8 is an independent module, which is detachably installed on the limiting plate 5 by snap-fit, adhesive, etc., to adapt to pipe bodies 1 of different specifications.

[0123] The above embodiments do not specifically limit the location of the pipe cap temporary storage position 18. In other embodiments, the pipe cap temporary storage position 18 may also be set on another separate support frame next to the limiting plate 5.

[0124] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
