Description

Technical Field

[0001] This utility model relates to the field of automated assembly technology, and in particular to a cannulation device. Background Technology

[0002] Cleaning equipment typically contains hoses that form liquid loops, which connect to corresponding components within the equipment via connectors. During assembly, to reduce manual labor and improve efficiency, intubation machines are used to automatically connect the hoses and connectors. In existing intubation machines, the hose and connector are placed on separate positioning blocks, then pressed together by corresponding pressure structures. The hose is then moved towards the connector, allowing it to be inserted.

[0003] However, the positioning block uses contoured grooves to position the hose and connector, and the concentricity accuracy of the hose and connector is difficult to guarantee completely. During the insertion process, the hose and connector are easily damaged, affecting the insertion quality.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0005] The purpose of this invention is to provide a cannulation device that ensures the concentricity accuracy of the hose and connector after positioning, thereby improving the insertion quality.

[0006] The purpose of this utility model is achieved through the following technical solution: a cannulation device for connecting a connector and a flexible tube, the connector comprising two insertion portions facing different directions, including:

[0007] The first fixture includes at least a first positioning pin, and one of the insertion portions of the connector is adapted to be positioned on the first positioning pin.

[0008] A transfer mechanism is connected to the first fixture in a transmission manner to drive the first fixture to move along the axial direction of the other insertion part;

[0009] The second fixture is arranged opposite to the first fixture and includes at least a second positioning pin. One end of the hose is adapted to be positioned on the second positioning pin, and the other end of the hose is arranged coaxially with another insertion portion of the connector.

[0010] The first fixture is adapted to approach the second fixture under the drive of the transfer mechanism, so that another plug portion of the connector is inserted into the other end of the hose.

[0011] Furthermore, the two plug portions of the connector are coaxial and arranged back to back, the second positioning pin is coaxial with the first positioning pin, and the first fixture is adapted to approach the second fixture along the axial direction of the first positioning pin and / or the second positioning pin under the drive of the transfer mechanism, so that the other plug portion of the connector is inserted into the other end of the hose.

[0012] Furthermore, the first fixture includes a first fixture seat that is pulsatorically connected to the transfer mechanism, and the number of the first positioning pins is at least one, with one end of the pin connected to the first fixture seat;

[0013] The second fixture includes a second fixture base, one end of the second positioning pin is connected to the second fixture base, and the second fixture corresponds one-to-one with the first positioning pin.

[0014] Furthermore, the axial direction of the first positioning pin and / or the second positioning pin is a first horizontal direction, and multiple first positioning pins are arranged at intervals along a second horizontal direction perpendicular to the first horizontal direction, and multiple second fixtures are arranged along the second horizontal direction to correspond one-to-one with the first positioning pins.

[0015] Furthermore, the first fixture seat has a row of the first positioning pins on both sides of the first horizontal direction, the two rows of the first positioning pins are at the same horizontal height and are staggered along the second horizontal direction.

[0016] Furthermore, the first positioning pin includes a first column and a second column coaxially connected to one end of the first column. The other end of the first column is connected to the first fixture seat. The outer contour dimension of the cross-section of the first column is larger than that of the cross-section of the second column. The insertion part is adapted to be sleeved on the second column through its inner hole and axially abut against the end of the first column.

[0017] The second positioning pin includes a third column and a fourth column coaxially connected to one end of the third column. The other end of the third column is connected to the second fixture seat. The outer contour dimension of the cross-section of the third column is larger than that of the cross-section of the fourth column. The flexible tube is adapted to be sleeved on the fourth column through its inner hole and axially abuts against the end of the third column.

[0018] Furthermore, the first positioning pin is detachably fixedly connected to the first fixture seat, and the second positioning pin is detachably fixedly connected to the second fixture seat.

[0019] Furthermore, the cannulation device also includes a clamping mechanism for clamping or releasing the tubing, the clamping mechanism corresponding one-to-one with the second fixture, and the clamping mechanism being adapted to cooperate with the second positioning pin to support the tubing.

[0020] Furthermore, the clamping mechanism includes:

[0021] The clamping drive has two output terminals;

The clamping blocks are provided with clamping grooves that are adapted to the contour of the hose on the side facing the hose.

[0023] The clamping blocks are adapted to come closer together under the drive of the clamping drive member to clamp and support the hose.

[0024] Furthermore, when the clamping mechanism clamps the hose, the connector inserted into the hose disengages from the first positioning pin in response to the first fixture moving away from the second fixture.

[0025] Compared with the prior art, the present invention has the following advantages: The present invention uses a first positioning pin and a second positioning pin to position the connector and the hose respectively. Compared with the positioning block with a contour groove, the positioning pin has a simple structure, low maintenance cost, and can accurately position the connector and / or hose without the need for a pressing structure, simplifying the overall structure of the insertion device, reducing costs, and the second positioning pin can also limit the deformation of the hose, resulting in good hose stability; the positioning pins for positioning the connector and hose have high positioning accuracy, ensuring that the insertion part of the hose to be inserted is precisely concentric with the end of the hose, and can accurately align during the insertion process, making it less likely to damage the hose and connector, thus improving the insertion quality; in addition, since the hose is usually a soft and flexible structure, while the connector is a relatively rigid component, the transfer mechanism is connected to the first fixture, allowing the connector to actively insert into the fixed hose, making the insertion process more stable and controllable, and minimizing damage to the hose.

It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.

[0036] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments.

[0037] Please see Figure 1 and Figure 2As shown, a cannulation device, corresponding to a preferred embodiment of the present invention, is used to insert a hose 520 into the insertion portion 511 of a connector 510. In one application scenario, the cannulation device is suitable for the cannulation operation between the hose 520 and the connector 510 in a sweeping machine, realizing automated or semi-automated installation between the hose 520 and the connector 510. The hose 520 has a channel for conveying liquid inside. The connector 510 is a two-way connector, which includes two insertion portions 511 facing different directions. The cannulation device allows one of the insertion portions 511 of the connector 510 to be inserted into the hose 520, thereby replacing the manual cannulation operation, effectively saving labor costs and improving work efficiency.

[0038] It should be noted that the application scenarios of the aforementioned cannulation machine are not limited to the cannulation of the flexible hose 520 of a sweeper, but can also be applied to other fields that require flexible hose 520 insertion. It is worth noting that the cannulation device is not limited to the insertion of flexible hose 520, but can also be used for the insertion of rigid pipes. The following description uses the insertion of flexible hose 520 as an example, but based on the above description, the scope of protection of this utility model is not limited thereto.

[0039] Furthermore, the cannulation device includes a first fixture 100, a transfer mechanism 200, and a second fixture 300. The first fixture 100 includes at least a first positioning pin 110. One of the insertion portions 511 of the connector 510 is adapted to be positioned on the first positioning pin 110. Specifically, the insertion portion 511 can be sleeved outside the first positioning pin 110 or inserted inside the first positioning pin 110, as long as it can ensure that the insertion portion 511 and the first positioning pin 110 are centered and fitted. In this embodiment, it is preferred to sleeve it outside the first positioning pin 110, which makes it more convenient for the operator to operate and allows for a direct visual judgment of whether the insertion portion 511 is installed in place. The transfer mechanism 200 is drivenly connected to the first fixture 100 to drive the first fixture 100 to move along the axial direction of the other insertion portion 511. The second fixture 300 is arranged opposite to the first fixture 100. It includes at least a second positioning pin 310. One end of the hose 520 is adapted to be positioned on the second positioning pin 310. The hose 520 is also preferably sleeved on the outside of the first positioning pin 110. The specific reasons are detailed above and will not be repeated here.

[0040] After the connector 510 and the hose 520 are positioned, the other plug portion 511 of the connector 510 is opposite to and coaxially arranged with the other end of the hose 520. The first fixture 100 is adapted to approach the second fixture 300 under the drive of the transfer mechanism 200, so that the other plug portion 511 of the connector 510 is inserted into the other end of the hose 520.

[0041] This invention uses a first positioning pin 110 and a second positioning pin 310 to position the connector 510 and the hose 520 respectively. Compared with a positioning block with a contour groove, the positioning pin structure is simple, has low maintenance costs, and can accurately position the connector 510 and / or hose 520 without the need for a pressing structure, simplifying the overall structure of the insertion device, reducing costs, and the second positioning pin 310 can also limit the deformation of the hose 520, resulting in good stability of the hose 520; the positioning pins are used to position the connector 510 and hose 520. Its high positioning accuracy ensures that the insertion part 511 and the end of the hose 520 are precisely concentric, enabling accurate alignment during insertion and minimizing damage to the hose 520 and connector 510, thus improving insertion quality. Furthermore, since the hose 520 is typically a soft and flexible structure, while the connector 510 is a relatively rigid component, the transfer mechanism 200 is connected to the first fixture 100, allowing the connector 510 to actively insert into the fixed hose 520. This makes the insertion process more stable and controllable, with less damage to the hose 520.

[0042] In this embodiment, the two insertion portions 511 of the connector 510 are coaxial and arranged back to back. Correspondingly, the second positioning pin 310 is coaxially arranged with the first positioning pin 110, and the first fixture 100 is adapted to approach the second fixture 300 along the axial direction of the first positioning pin 110 and / or the second positioning pin 310 under the drive of the transfer mechanism 200, so that the other insertion portion 511 of the connector 510 is inserted into the other end of the hose 520.

[0043] Furthermore, the first fixture 100 includes a first fixture base 120, which is connected to the transfer mechanism 200. There is at least one first positioning pin 110, with one end connected to the first fixture base 120. The second fixture 300 includes a second fixture base 320, with one end of a second positioning pin 310 connected to the second fixture base 320. The second fixture 300 corresponds one-to-one with the first positioning pin 110.

[0044] This utility model adopts the above-described structure. When there are multiple first positioning pins 110, they are all connected to the same first fixture seat 120. Then, the synchronous driving and insertion operation of multiple connectors 510 are realized through the same transfer mechanism 200. The insertion is efficient, while avoiding the need to add more transfer mechanisms 200, simplifying the structure and reducing costs. By setting multiple second fixtures 300 that correspond one-to-one with the first positioning pins 110, each second fixture 300 is independent of each other, so that each second fixture 300 can be installed and adjusted individually, making the adjustment more convenient and ensuring that each adjusted second positioning pin 310 is coaxially arranged with the corresponding first positioning pin 110.

[0045] Furthermore, the axial direction of the first positioning pin 110 and / or the second positioning pin 310 is the first horizontal direction, which makes it more convenient to install the connector 510 and / or the hose 520, and the positioning reliability of the connector 510 and / or the hose 520 after being positioned by the positioning pin is better. Multiple first positioning pins 110 are arranged at intervals along a second horizontal direction perpendicular to the first horizontal direction, and multiple second fixtures 300 are arranged along the second horizontal direction, corresponding one-to-one with the first positioning pins 110.

[0046] Preferably, the first fixture base 120 has a row of first positioning pins 110 on both sides of the first horizontal direction, and a row of second fixtures 300 on both sides of the first fixture base 120 in the first horizontal direction. The transfer mechanism 200 can drive the first fixture 100 to move to the second fixtures 300 on different sides. Specifically, the transfer mechanism 200 can be a linear module with a motor and a lead screw, which can move precisely in both directions along the first horizontal direction.

[0047] Since the volume of each second fixture 300 is much larger than that of the first positioning pin 110, when the second fixtures 300 are arranged in a straight line, the number that can be arranged within a given width (second horizontal direction) is limited. This utility model adopts a double-sided layout, utilizing the space on both sides of the first fixture base 120 in the first horizontal direction, directly increasing the number of workstations from N in a single row to 2N in a double row, thus achieving a leapfrog increase in production capacity.

[0048] Preferably, the two rows of first locating pins 110 are at the same horizontal height, so that the specifications of each second fixture 300 are uniform, reducing manufacturing costs, improving interchangeability, and making disassembly and maintenance more convenient. The two rows of first locating pins 110 are staggered along the second horizontal direction, that is, the projections of the two rows of first locating pins 110 in the first horizontal direction do not overlap, so that the two rows of first locating pins 110 have sufficient installation space and avoid mutual restriction during installation.

[0049] Furthermore, referring to Figure 3 and Figure 4 As shown, the first positioning pin 110 includes a first column 111 and a second column 112. The second column 112 is coaxially connected to one end of the first column 111, and the other end of the first column 111 is connected to the first fixture seat 120. The first column 111 and the second column 112 are preferably integrally formed to improve the connection strength between them. The outer contour dimension of the cross-section of the first column 111 is larger than the outer contour dimension of the cross-section of the second column 112. The outer circumference of the first column 111 is circular, and its outer diameter is not larger than the inner diameter of the inner hole of the insertion part 511, facilitating the insertion part 511 to fit into or remove from the first positioning pin 110. In this embodiment, the outer diameter is preferably the same to ensure optimal positioning effect.

[0050] The insertion part 511 is adapted to be sleeved on the outside of the second column 112 through its inner hole, so as to achieve coaxial positioning of the insertion part 511 and the second column 112, and the insertion part 511 axially abuts against the end of the first column 111. When the insertion part 511 is inserted into the hose 520 along the first horizontal direction, the insertion part 511 is limited by the end of the first column 111 in the axial direction, so as to achieve axial positioning of the insertion part 511. The insertion part 511 can be reliably inserted into the hose 520 without the need for an additional clamping structure to fasten the connector 510 to the first positioning pin 110, which simplifies the structure, reduces costs, and makes it very convenient to assemble and disassemble the connector 510 at the first fixture 100.

[0051] In one embodiment, the first positioning pin 110 can be fixed to the first fixture seat 120 by welding or integral molding. Preferably, in this embodiment, the first positioning pin 110 and the first fixture seat 120 are detachably fixedly connected, so that when it is necessary to insert tubes into different types of connectors 510, only the first positioning pin 110 needs to be disassembled and replaced.

[0052] Specifically, the end of the first column 111 furthest from the second column 112 is recessed inward to form a connecting hole 113. The first fixture seat 120 has a through-hole 121 coaxial with the connecting hole 113. The mounting hole 121 includes a first segment 1211 and a second segment 1212 connected to each other. The first segment 1211 is closer to the connecting hole 113 than the second segment 1212, and the inner diameter of the first segment 1211 is smaller than the inner diameter of the second segment 1212. The first fixture 100 includes a fastener 130, which is a threaded component such as a bolt or screw. The fastener 130 includes a threaded portion 131 and a cap portion 132 connected to one end of the threaded portion 131. The first column 111 abuts against the side of the first fixture seat 120 perpendicular to the first horizontal direction. The screw portion 131 passes sequentially through the second section 1212 and the first section 1211 from the side opposite to this side, and partially extends out of the first section 1211, and is threaded into the connecting hole 113. The cap portion 132 is received in the mounting hole 121. As the screw portion 131 and the first column 111 are tightened together, the cap portion 132 abuts against the stepped surface between the first section 1211 and the second section 1212, while the first column 111 abuts against the first fixture seat 120, so that the first positioning pin 110 is fixed to the first fixture seat 120.

[0053] Preferably, the outer contour of the first column 111 is non-circular, such as a hexagonal, octagonal or other polygonal contour, which makes it easier for the operator to grip the first column 111 when disassembling or assembling the first positioning pin 110, and prevents the first positioning pin 110 from rotating synchronously when the fastener 130 is screwed into or out of the connecting hole 113 by a screwdriver or other tool. At the same time, it also makes it easier for the operator to apply a rotational force to the first positioning pin 110 to rotate it in the opposite direction to the rotation of the fastener 130, thereby improving the disassembly and assembly efficiency.

[0054] Furthermore, referring to Figure 5 and Figure 6 As shown, the second positioning pin 310 includes a third column 311 and a fourth column 312. The fourth column 312 is coaxially connected to one end of the third column 311, and the other end of the third column 311 is connected to the second fixture seat 320. The outer contour dimension of the cross-section of the third column 311 is larger than that of the cross-section of the fourth column 312. The flexible tube 520 is adapted to be sleeved on the outside of the fourth column 312 through its inner hole and axially abuts against the end of the third column 311. When the insertion part 511 is inserted into the flexible tube 520 along the first horizontal direction, the flexible tube 520 is limited in the axial direction by the end of the third column 311, realizing the axial positioning of the flexible tube 520 and ensuring that the insertion part 511 is reliably inserted into the flexible tube 520. The structure of the second positioning pin 310 is the same as or similar to the structure of the first positioning pin 110, and will not be described in detail here.

[0055] Preferably, when the hose 520 abuts against the third column 311, there is a certain distance between the end of the fourth column 312 away from the third column 311 and the end of the hose 520 to be inserted into the insertion part 511. This distance is not less than the length of the insertion part 511, so as to prevent the third column 311 from obstructing the insertion part 511 from being inserted into the hose 520.

[0056] Preferably, the second positioning pin 310 and the second fixture seat 320 are detachably fixedly connected. When it is necessary to adapt to different models of hoses 520, only the second positioning pin 310 needs to be disassembled and replaced. The connection structure between the second positioning pin 310 and the second fixture seat 320 is the same as the connection structure between the first positioning pin 110 and the first fixture seat 120, and will not be described again here.

[0057] Furthermore, since the hose 520 is typically quite long, the length of the fourth post 312 also needs to be increased accordingly to ensure that the hose 520, fitted onto the fourth post 312, can be stably supported on the fourth post 312, while preventing the end of the hose 520 to be inserted from becoming eccentric. However, if the fourth post 312 is too long, the disassembly and assembly stroke of the hose 520 will also become longer, making it very inconvenient to disassemble and assemble the hose 520 at the second locating pin 310.

[0058] In a preferred embodiment, the insertion device further includes a clamping mechanism 400 corresponding to the second fixture 300. The clamping mechanism 400 is adapted to clamp and support the hose 520 positioned on the second positioning pin 310. The clamping mechanism 400 and the second positioning pin 310 can cooperate to support the hose 520, so that the length of the fourth column 312 does not need to be excessively long. In this embodiment, at least a portion of the hose 520 in a suspended state can be clamped and supported by the clamping mechanism 400 to prevent a large part of the hose 520 from being suspended in the air, ensuring that the end of the hose 520 to be inserted is concentric with the insertion part 511.

[0059] Specifically, the clamping mechanism 400 includes a clamping drive 410 and clamping blocks 420. The second fixture seat 320 can be stacked on the clamping drive 410, making the second fixture 300 more compact and improving space utilization. The clamping drive 410 has two output ends, and the number of clamping blocks 420 is two, which are connected to different output ends of the clamping drive 410. The clamping drive 410 can be a finger cylinder, which has a simple structure and small size, reducing the space occupied by the entire second fixture 300. The two clamping blocks 420 are respectively disposed on both sides of the hose 520 in the radial direction. In this embodiment, they are specifically arranged opposite to each other on both sides of the hose 520 along the second horizontal direction, which facilitates the placement and removal of the hose 520. The clamping block 420 has a clamping groove 421 on the side facing the hose 520 that is adapted to the contour of the hose 520. The two clamping blocks 420 are adapted to move closer to each other under the drive of the clamping drive member 410, so that the clamping groove 421 clamps and supports the hose 520.

[0060] The clamping groove 421 is specifically an arc-shaped groove, with its axis parallel to the axis of the second positioning pin 310. Both ends of the clamping groove 421 are open in the axial direction. The clamping groove 421 has a first end and a second end in the axial direction. The first end is adjacent to one end of the second column 111 connected to the second column 112, and the second end is closer to the second fixture 300 than the other end of the second column 112. When the hose 520 is clamped in the clamping block 420, the end of the hose 520 that is connected to the insertion part 511 protrudes relative to the second end to facilitate the insertion operation.

[0061] Preferably, the clamping groove 421 has a first recess 422 near the second end. The first recess 422 extends through the second end along the axial direction of the hose 520. A gap exists between the first recess 422 and the hose 520 to accommodate the insertion deformation of the hose 520, so as to prevent the clamping groove 421 from obstructing the insertion of the insertion part 511 into the hose 520. The length of the first recess 422 in the axial direction is configured to accommodate the deformation of the hose 520 throughout the insertion process. Specifically, the first recess 422 is also an arc-shaped groove, coaxially arranged with the clamping groove 421, and its radius is larger than that of the clamping groove 421.

[0062] In addition, during actual production, some parts 521 are assembled on the outer periphery of some hoses 520 before they are inserted into the connector 510. At this time, the clamping block 420 can also have a second recess 423 recessed inward in the corresponding area to avoid the parts.

[0063] Preferably, when the clamping mechanism 400 clamps the hose 520, the connector 510 inserted into the hose 520 disengages from the first positioning pin 110 in response to the first fixture 100 moving away from the second fixture 300. This allows the inserted hose 520 and connector 510 to remain on the second fixture 300. The operator can unload the hoses 520 and connectors 510 on this row of second fixtures 300 and continue to load new hoses 520. At the same time, the first fixture 100 can move to another row of second fixtures 300 to continue the insertion operation. The loading and unloading and insertion operations are carried out in parallel, which effectively improves work efficiency.

[0064] Since the hose 520 and the connector 510 are tightly fitted, while the connector 510 and the first positioning pin 110 are not tightly fitted, the connector 510 can smoothly disengage from the first positioning pin 110 during the process of the second fixture 300 moving away from the first fixture 100, and there will be no loosening between the connector 510 and the hose 520.

[0065] Furthermore, return Figure 1 As shown, the cannulation device also includes a platform 600, with each second fixture 300 mounted on the platform 600. A transfer mechanism 200 is located below the platform 600. The platform 600 has a vertically extending clearance hole 610. A first fixture 100 is located above the platform 600. The first fixture 100 and the output end of the transfer mechanism 200 are connected via a connecting bracket 700, which is housed within the clearance hole 610. A gap exists between the inner wall of the clearance hole 610 and the connecting bracket 700, allowing the first fixture 100 to move towards the second fixture 300.

[0066] With the above structure, the table surface of the platform 600 is clean and spacious, which is convenient for operators to load and unload materials; the transfer mechanism 200 and the operating area above the platform 600 are isolated by the platform 600, which improves the safety of operation and allows operators to observe the insertion process more intuitively, which is convenient for visual inspection of quality and quick detection of abnormalities.

[0067] The transfer mechanism 200 is adapted to drive the first fixture 100 to an initial position, allowing the operator to place the connector 510 to be inserted onto the first positioning pins 110 on both sides of the first fixture base 120. In this embodiment, the initial position refers to the position where the first fixture 100 is located in the middle of the platform 600, equidistant from the second fixtures 300 on both sides. This design ensures that there is sufficient and equal operating space on both sides of the first fixture 100, avoiding the operator's inability to load the connector 510 due to insufficient spacing on one side; in addition, the transfer mechanism 200 drives the first fixture 100 to move to the second fixtures 300 on both sides with the same stroke, which helps the wear distribution of the transfer mechanism 200 to be more uniform after long-term use, thereby extending the service life of the entire transfer mechanism 200.

[0068] The working process of this intubation device is as follows: The transfer mechanism 200 first moves the first fixture 100 to the initial position. The operator places the connectors 510 to be inserted one by one onto the first positioning pins 110 of the first fixture 100, and places the tubing 520 one by one onto the second positioning pins 310 of each second fixture 300. Then, the clamping mechanism 400 retracts to clamp the tubing 520. Afterward, the transfer mechanism 200 moves the first fixture 100 to one row of second fixtures 300, so that the connectors 510 corresponding to that row of first fixtures 100 are inserted into the first fixture 100. The connector 511 of the connector 10 is inserted into the hose 520; then the transfer mechanism 200 drives the first fixture 100 to move in the opposite direction to another row of second fixtures 300, so as to continue to insert the connector 511 of the connector 510 corresponding to the second fixture 300 into the hose 520; during this process, when the connector 510 and the hose 520 are connected and the first fixture 100 moves away from the connector 510, the corresponding clamping mechanism 400 releases the connector 510 and the hose 520, and the operator unloads it and reloads a new hose 520.
