Description

Technical Field

[0001] This utility model relates to the field of automated assembly technology, and in particular to an automatic tube insertion machine. Background Technology

[0002] Cleaning equipment typically contains connecting pipes to form liquid loops for transporting wastewater or clean water. These liquid loops are usually quite long, requiring multiple pipes to be connected together using various connectors.

[0003] Existing cannulation equipment typically operates in a single-channel, sequential mode. When the connector is a two-way or three-way connector, the equipment must align and insert them one by one, making it impossible to continuously insert multiple connecting pipes and corresponding connectors. This operation method significantly slows down the docking speed and affects the overall production cycle.

[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 an automatic cannulation machine, which eliminates the need for manual handling and adjustment of each insertion part of a single connector, thereby improving the production line cycle time.

[0006] The purpose of this utility model is achieved through the following technical solution: an automatic cannulation machine for inserting a connector and a flexible tube, wherein the connector includes at least two insertion parts, including:

[0007] A first fixture is used to receive and position the connector, and can apply force to fix the connector thereon;

[0008] The second fixture corresponds one-to-one with the insertion part. The second fixture is used to accommodate and position the hose, and can apply force to fix the hose thereon.

[0009] The transfer mechanism is connected to the first fixture via a transmission mechanism;

[0010] The transfer mechanism is adapted to drive the first fixture to move sequentially toward each of the second fixtures, so that each of the plug-in portions is inserted into the hose on the corresponding second fixture, and the second fixture releases the hose in response to the insertion of the corresponding plug-in portion into the hose.

[0011] Furthermore, the transfer mechanism is adapted to drive the first fixture to an initial position, in which each of the plug-in portions is coaxially arranged with the corresponding hose on the second fixture.

[0012] Furthermore, the transfer mechanism includes at least one transfer module, each of which drives the connector to move in a straight line direction, and the driving direction is parallel to the axial direction of one or more of the insertion portions on the connector to be inserted.

[0013] Furthermore, the connector is a T-type connector, and the transfer mechanism includes:

[0014] The first transfer module has a driving direction parallel to the axial direction of two of the plug-in portions;

[0015] The second transfer module is connected to the first transfer module and the first fixture respectively, and its driving direction is parallel to the axial direction of the other plug-in part.

[0016] Two of the parallel axial connectors are adapted to be inserted into the corresponding hoses under the drive of the first transfer module, and the other connector is adapted to be inserted into the corresponding hoses under the drive of the second transfer module.

[0017] Furthermore, the first fixture includes:

[0018] The first fixture base has a first positioning groove that is adapted to the outer contour of the connector;

[0019] A first clamping structure is disposed on the first fixture seat and is adapted to move and abut the connector against the first positioning groove;

[0020] The first clamping structure is a manually driven clamping structure.

[0021] Furthermore, the second fixture includes:

[0022] The second fixture seat has a second positioning groove that is adapted to the outer contour of the hose;

[0023] The second clamping structure has a third positioning groove that is adapted to the outer contour of the hose;

[0024] The second clamping structure is adapted to move and approach the second fixture seat, so that the hose is clamped between the second positioning groove and the third positioning groove.

[0025] Furthermore, both the second positioning groove and the third positioning groove have a proximal end that is close to and flush with the first fixture and a distal end that is far from the first fixture, at least the proximal end is an open end, and one end of the hose extends out of the second fixture through the proximal end;

[0026] The second positioning groove and the third positioning groove have a recess in the region near the proximal end. The recess extends through the proximal end along the axial direction of the hose. There is a gap between the recess and the hose to accommodate the hose insertion deformation.

[0027] Furthermore, the second clamping structure includes:

[0028] The clamping member is arranged opposite to the second fixture seat and has the third positioning groove;

[0029] A clamping drive is connected to the clamping member in a transmission manner, and is adapted to drive the clamping member to clamp or release the hose;

[0030] Each of the second fixtures is arranged in a different position on the first fixture, at least one of the second fixtures is a side-pressing clamping structure to provide space for loading and unloading materials from the first fixture, and the remaining second fixtures are downward-pressing clamping structures.

[0031] Furthermore, when the second fixture is a side-pressure clamping structure, the second fixture seat and the clamping member are arranged opposite each other in the horizontal direction, and the second positioning groove and the third positioning groove are respectively formed on the opposite sides of the second fixture seat and the clamping member;

[0032] The second fixture also includes a support rod located below the second positioning groove and the third positioning groove. One end of the support rod is fixedly connected to the clamping member, and the other end passes through the second fixture seat and can extend and retract along the moving direction of the clamping member.

[0033] The hose is adapted to be carried on the support rod and corresponds to the second positioning groove and the third positioning groove.

[0034] Furthermore, the automatic intubation machine includes a platform, each of the second fixtures is disposed on the platform surface of the platform, the transfer mechanism is located below the platform, the platform has a clearance hole extending through it in the vertical direction, the first fixture is received in the clearance hole, part of the first fixture is located above the platform to accommodate and position the connector, and part is located below the platform to connect with the transfer mechanism, and there is a gap between the inner wall of the clearance hole and the first fixture to allow the first fixture to move toward each of the second fixtures.

[0035] Compared with the prior art, this utility model has the following beneficial effects: The present utility model adopts the above-mentioned structure, where the first fixture and the second fixture respectively accommodate and position the connector and the hose, ensuring that the connector and the hose are in precise preset positions before each insertion. This eliminates the need for manual pre-insertion of the connector and hose before the insertion machine completes the remaining insertion work, reducing manual operation, lowering labor intensity, and improving consistency and repeatability to increase efficiency. Simultaneously, reduced manual intervention lowers the risk of pinching injuries and incorrect insertion. By setting multiple second fixtures, after the connector is positioned in the first fixture, each insertion part of the connector corresponds one-to-one with a second fixture, and the transfer mechanism drives the first fixture to move. This allows each connector to be inserted sequentially into different hoses. The insertion of a single connector does not require multiple manual handling and adjustments, saving labor costs and reducing operation time, thus greatly improving the production line cycle time. In addition, compared to connecting the transfer mechanism to the second fixture, connecting the transfer mechanism to the first fixture eliminates the need for multiple sets of transfer mechanisms, simplifying the structure and making the insertion machine more compact. Furthermore, since hoses are typically flexible and easy to bend, while connectors are relatively rigid components, the connection between the transfer mechanism and the first fixture allows 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. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0046] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0047] 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. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0048] Please see Figure 1 and Figure 2As shown, an automatic tube insertion machine, corresponding to a preferred embodiment of this utility model, is used to insert a hose 600 into the insertion portion 510 of a connector 500. In one application scenario, the tube insertion machine is suitable for tube insertion operations between the hose 600 and the connector 500 within a sweeping machine, achieving automated or semi-automated installation between the hose 600 and the connector 500. The hose 600 has a channel for conveying liquid inside. The connector 500 can be various types of pipe connectors, such as two-way connectors or three-way connectors. The connector 500 includes at least two insertion portions 510. The tube insertion machine enables each insertion portion 510 of the connector 500 to be sequentially inserted into different hoses 600, thereby replacing manual tube insertion operations, effectively saving labor costs and improving work efficiency.

[0049] It should be noted that the application scenarios of the aforementioned tube insertion machine are not limited to the tube insertion operation of the flexible hose 600 of a sweeping machine, but can also be applied to other fields with flexible hose 600 insertion requirements. It is worth noting that the tube insertion machine is not limited to the tube insertion operation of the flexible hose 600, but can also be used for the tube insertion operation of rigid tubes. The following description uses the insertion of the flexible hose 600 as an example, but based on the above description, the scope of protection of this utility model is not limited thereto.

[0050] Furthermore, the automatic intubation machine includes a first fixture 100, a second fixture 200, and a transfer mechanism 300. The first fixture 100 is used to receive and position the connector 500, and can apply force to fix the connector 500 thereon. The second fixture 200 corresponds one-to-one with the insertion part 510, and is used to receive and position the tubing 600, and can apply force to fix the tubing 600 thereon. The transfer mechanism 300 is drivenly connected to the first fixture 100, and is used to drive the first fixture 100 to move sequentially to each of the second fixtures 200, so that each insertion part 510 is inserted into the tubing 600 on the corresponding second fixture 200, and the second fixture 200 releases the tubing 600 in response to the insertion of the corresponding insertion part 510 into the tubing 600.

[0051] This utility model adopts the above-described structure. The first fixture 100 and the second fixture 200 respectively accommodate and position the connector 500 and the hose 600, ensuring that the connector 500 and the hose 600 are in precise preset positions before each insertion. This eliminates the need for manual pre-insertion of the connector 500 and hose 600 before the insertion machine completes the remaining insertion work, reducing manual operation, lowering labor intensity, improving consistency and repeatability, and thus increasing efficiency. Simultaneously, reduced manual intervention lowers the risk of pinching injuries and incorrect insertion. By setting multiple second fixtures 200, after the connector 500 is positioned in the first fixture 100, each insertion part 510 of the connector 500 corresponds one-to-one with a second fixture 200. The transfer mechanism 300 drives the first fixture 100 to move, enabling each insertion part 510 to... 10 are sequentially inserted into different hoses 600. The insertion operation of a single connector 500 does not require multiple manual handling and adjustments, which saves labor costs and reduces operation time, greatly improving the production line cycle time. In addition, compared with connecting the transfer mechanism 300 to the second fixture 200, connecting the transfer mechanism 300 to the first fixture 100 eliminates the need for multiple sets of the transfer mechanism 300, simplifying the structure and making the insertion machine more compact. Since the hose 600 is usually a soft and flexible structure, while the connector 500 is a relatively rigid component, the connection between the transfer mechanism 300 and the first fixture 100 allows the connector 500 to actively insert into the fixed hose 600, making the insertion process more stable and controllable, and minimizing damage to the hose 600.

[0052] Furthermore, the transfer mechanism 300 is adapted to drive the first fixture 100 to an initial position. In the initial position, an operator or an automated conveying structure can load the connector 500 to be inserted onto the first fixture 100, or remove the connector 500 after insertion from the first fixture 100. When the first fixture 100 is in the initial position, each insertion portion 510 of the connector 500 thereon is coaxially arranged with the corresponding hose 600 on the second fixture 200. With the above structure, the alignment step is completed before the insertion action begins. Starting from this position, the transfer mechanism 300 only needs to perform a simple linear insertion motion to achieve the insertion of the insertion part 510 and the hose 600, which greatly improves the success rate and accuracy of insertion. Since perfect coaxial alignment has been achieved in the initial position, the insertion machine does not need to design complex path planning or real-time correction algorithms for the insertion process. The above insertion motion is very stable and has extremely high repeatability, avoiding the complexity of multi-axis linkage and the possible trajectory errors, making the whole process very reliable. In addition, the initial position is a clear and measurable physical position. When the equipment needs maintenance or the accuracy deviates, technicians can perform calibration and restoration based on the initial position, making the debugging work more convenient and faster with a clear benchmark.

[0053] The transfer mechanism 300 includes at least one transfer module, which can be a linear module or a linear cylinder. Each transfer module drives the connector 500 to move along a linear direction, and this driving direction is parallel to the axial direction of one or more insertion portions 510 on the connector 500 to be inserted. Preferably, when there are insertion portions 510 with parallel axial directions on the connector 500, these insertion portions 510 can share one transfer module for drive insertion, which simplifies the structure of the transfer mechanism 300 and reduces costs.

[0054] As a specific embodiment, the cannulation machine of this utility model is mainly used for cannulation operations on different types of T-joints. The connector 500 has two back-to-back insertion parts 510 with collinear axes, and a insertion part 510 with an axis perpendicular to the two insertion parts 510. In this case, the transfer mechanism 300 includes a first transfer module 310 and a second transfer module 320. The driving direction of the first transfer module 310 is parallel to the axial direction of two of the insertion parts 510, and the driving direction of the second transfer module 320 is parallel to the axial direction of the other insertion part 510. The second transfer module 320 is connected to both the first transfer module 310 and the first fixture 100, enabling the first fixture 100 to move along a straight line under the drive of the first transfer module 310 and along another straight line under the drive of the second transfer module 320. The first transfer module 310 and the second transfer module 320 can be moved to their respective origin positions, placing the first fixture 100 in its initial position. The first transfer module 310 can drive the first fixture 100 from its initial position to a first insertion position and a second insertion position. In the first insertion position, one insertion part 510 is inserted into a flexible tube 600, and in the second insertion position, another insertion part 510 is inserted into a flexible tube 600. The second transfer module 320 can drive the first fixture 100 from its initial position to a third insertion position, where another non-collinear insertion part 510 is inserted into a flexible tube 600.

[0055] Since the first transfer module 310 needs to move to three positions during actual cannulation, it is preferably a linear module, which is driven by a lead screw and a motor to improve displacement accuracy. The second transfer module 320 only needs to move to two positions, and it is preferably a linear cylinder to simplify the structure and reduce costs.

[0056] Further, the first fixture 100 includes a first fixture base 110 and a first clamping structure 120. The first fixture base 110 has a first positioning groove 111 adapted to the outer contour of the connector 500. The first positioning groove 111 is preferably recessed inward from the top of the first fixture base 110 to facilitate loading and unloading operations. The first clamping structure 120 is disposed on the first fixture base 110 and is adapted to move and press the connector 500 against the first positioning groove 111. The first clamping structure 120 can be an automatic or manual driven clamping structure. In this embodiment, loading and unloading at the first fixture 100 is done manually. The first clamping structure 120 is preferably a manually driven clamping structure to improve safety. Moreover, the first clamping structure 120 can be driven incidentally during manual loading and unloading, so the overall insertion efficiency will not be significantly affected. The first clamping structure 120 can specifically be a quick clamp, such as a clamp, which is a known structure and will not be described in detail here.

[0057] Preferably, the first fixture 100 and the transfer mechanism 300 can be detachably connected by bolts, screws, etc. When it is necessary to replace the connector 500 of a different model for tube insertion, simply detach the first fixture 100 from the transfer mechanism 300 and replace it with a suitable first fixture 100. Admittedly, in other embodiments, the part of the first fixture 100 with the first positioning groove 111 and other parts can also be detachably connected by bolts, screws, etc. When it is necessary to replace the connector 500 of a different model, simply replace the part with the first positioning groove 111.

[0058] Furthermore, referring to Figures 3 to 5 As shown, the second fixture 200 includes a second fixture base 210 and a second clamping structure 220. The second fixture base 210 has a second positioning groove 211 adapted to the outer contour of the hose 600. The second clamping structure 220 has a third positioning groove 2211 adapted to the outer contour of the hose 600. The second clamping structure 220 is adapted to move and approach the second fixture base 210, so that the hose 600 is clamped between the third positioning groove 2211 and the second positioning groove 211. In this embodiment, the second clamping structure 220 is preferably an automatically driven clamping structure, which can improve the feeding efficiency of the hose 600, and more importantly, can avoid manual intervention when the insertion parts 510 on the connector 500 are inserted sequentially.

[0059] The second clamping structure 220 includes a clamping member 221 and a clamping drive member 222. The clamping member 221 and the second fixture seat 210 are arranged radially opposite each other along the hose 600, and a third positioning groove 2211 is formed on the side of the clamping member 221 facing the second fixture seat 210. The clamping drive member 222 is a linear cylinder, which is kinetically connected to the clamping member 221 and is adapted to drive the clamping member 221 to move closer to or away from the second fixture seat 210 along the radial direction of the hose 600 to clamp or release the hose 600. Admittedly, in other embodiments, the second clamping structure 220 may also use a rotary drive member to drive the clamping member 221 to rotate and press against the second fixture seat 210. However, it is obvious that using a linear drive structure provides a better clamping effect for the clamping member 221.

[0060] Furthermore, both the second positioning groove 211 and the third positioning groove 2211 are arc-shaped grooves with their axial direction parallel to the axial direction of the hose 600, so as to better contact and limit the hose 600. The diameter of the second positioning groove 211 and the third positioning groove 2211 can be larger than the outer diameter of various hoses 600, so as to facilitate the adaptation of hoses 600 with various outer diameters.

[0061] Both the second positioning groove 211 and the third positioning groove 2211 have a proximal end near the first fixture 100 and a distal end away from the first fixture 100 in the axial direction. At least the proximal ends of the second positioning groove 211 and the third positioning groove 2211 are open and flush. When the hose 600 is clamped between the second positioning groove 211 and the third positioning groove 2211, one end of the hose 600 extends out of the second fixture 200 through the proximal end for insertion into the insertion portion 510 of the connector 500. The flush arrangement of the proximal ends of the second positioning groove 211 and the third positioning groove 2211 can reliably clamp and limit the end of the hose 600 near the second fixture 200, ensuring that the hose 600 is not easily displaced during insertion.

[0062] Since the inner diameter of the flexible tube 600 is typically slightly smaller than the outer diameter of the insertion portion 510 to ensure a tight connection after insertion, the flexible tube 600 will deform under the insertion force when the insertion portion 510 is inserted into it. Preferably, both the second positioning groove 211 and the third positioning groove 2211 have a recess 212 near the proximal end. The recess 212 extends along the axial direction of the flexible tube 600 to the proximal end, and there is a gap between the recess 212 and the flexible tube 600 to accommodate the insertion deformation of the flexible tube 600, so as to prevent the second positioning groove 211 and / or the third positioning groove 2211 from obstructing the insertion of the insertion portion 510 into the flexible tube 600. The length of the recess 212 in the axial direction is configured to accommodate the deformation of the flexible tube 600 throughout the insertion process.

[0063] In this embodiment, the recess 212 is also an arc-shaped groove. The recess 212 on the second positioning groove 211 is coaxially arranged with the second positioning groove 211 and its diameter is larger than that of the second positioning groove 211. The recess 212 on the third positioning groove 2211 is coaxially arranged with the third positioning groove 2211 and its diameter is larger than that of the third positioning groove 2211.

[0064] Furthermore, the distal ends of the second positioning groove 211 and the third positioning groove 2211 are also open ends, allowing them to extend from the distal end of the second fixture 200 when the hose 600 is long, thus improving adaptability to hoses 600 of different lengths. Preferably, the lengths of the second positioning groove 211 and the third positioning groove 2211 are less than the length of the hose 600, and when the hose 600 is fed to the preset position of the second fixture 200, the other end of the hose 600 protrudes relative to the distal ends of the second positioning groove 211 and the third positioning groove 2211. This allows the operator to avoid placing their hand between the clamping member 221 and the second fixture 200 when feeding the hose 600, improving safety.

[0065] Preferably, the length of the second positioning groove 211 is greater than the length of the third positioning groove 2211, so that the second positioning groove 211 has a guide section that protrudes relative to the third positioning groove 2211 in the axial direction. This guide section makes it easy for the operator to observe whether the hose 600 is in the correct position in the radial direction.

[0066] Furthermore, the second fixture 200 is preferably a downward-pressing clamping structure, that is, the second fixture seat 210 is located below the clamping member 221, the second positioning groove 211 is recessed inward from the top of the second fixture seat 210, and the third positioning groove 2211 is recessed inward from the bottom of the clamping member 221. When loading the hose 600, the operator can directly place the hose 600 in the second positioning groove 211, and then drive the clamping member 221 to descend through the clamping drive member 222 to clamp the hose 600, thus making the loading of the hose 600 very convenient.

[0067] However, the second fixture 200 of the above structure is relatively high, and since each second fixture 200 is arranged in a different position on the first fixture 100, it will block the first fixture 100, hindering the operator's operating space and line of sight, making it very inconvenient for the operator to load and unload materials at the first fixture 100.

[0068] As a preferred embodiment, refer to Figure 1 , Figure 6 and Figure 7 As shown, at least one second fixture 200 is a side-pressure clamping structure, that is, the second fixture seat 210 and the clamping member 221 are arranged opposite each other in the horizontal direction, and the second positioning groove 211 and the third positioning groove 2211 are formed on the opposite sides of the second fixture seat 210 and the clamping member 221.

[0069] By adopting a side-pressure clamping structure, the height and volume of the entire second fixture 200 can be significantly reduced. By specifically using a side-pressure structure on the side near the operator or in a space-constrained location, the low-profile design provides ample space for the operator to operate at the first fixture 100, greatly improving the convenience of loading and unloading the connector 500. The operator's hands can access and operate the first fixture 100 without obstruction, effectively avoiding interference with the surrounding second fixture 200, which improves both operating efficiency and safety.

[0070] However, with the second fixture 200 employing a side-pressure clamping structure, the hose 600 may fall out of the second positioning groove 211 when the operator loads it, due to gravity, making loading inconvenient. As a preferred embodiment, when the second fixture 200 adopts a side-pressure clamping structure, the second fixture base 210 further includes a support rod 230. The support rod 230 is located below the second positioning groove 211 and the third positioning groove 2211. One end of the support rod 230 is fixedly connected to the clamping member 221, and the other end passes through the second fixture base 210, and can extend and retract along the moving direction of the clamping member 221. The operator can place the hose 600 on the support rod 230 so that the hose 600 corresponds to the second positioning groove 211 and the third positioning groove 2211, facilitating the subsequent insertion of the hose 600 into the second positioning groove 211 when the clamping member 221 moves towards it.

[0071] By adopting the above structure, when the hose 600 is placed on the support rod 230, it can be radially limited between the second fixture seat 210 and the clamping member 221, preventing it from falling out of the second fixture 200, improving the positional reliability of the hose 600 on the second fixture 200, and as the clamping member 221 gradually moves towards the second fixture seat 210, the hose 600 on the support rod 230 can be clamped between the second positioning groove 211 and the third positioning groove 2211.

[0072] Specifically, the second fixture seat 210 has a guide hole 213 recessed inward on the side facing the clamping member 221. The axis of the guide hole 213 is parallel to the moving direction of the clamping member 221. One end of the support rod 230 is inserted into the guide hole 213 and can extend and retract along the axis of the guide hole 213. The other end of the support rod 230 is connected to the side of the clamping member 221 facing the second fixture seat 210 and is located below the third positioning groove 2211. In addition to supporting the hose 600, the support rod 230 also serves as a guide, ensuring that the clamping member 221 moves more accurately and smoothly towards the second fixture seat 210 along a preset path, thereby improving the reliability of the hose 600 after clamping.

[0073] Preferably, multiple support rods 230 are arranged at intervals along the axial direction of the second positioning groove 211 to support multiple positions of the hose 600, and the guide holes 213 correspond one-to-one with the support rods 230.

[0074] Furthermore, referring to Figure 1 As shown, the automatic intubation machine also includes a platform 400, with each second fixture 200 disposed on the platform surface of the platform 400. A transfer mechanism 300 is located below the platform 400. The platform 400 has a vertically extending clearance hole 410, into which a first fixture 100 is received. Part of the first fixture 100 is located above the platform 400 to accommodate and position the connector 500, and part is located below the platform 400 to connect with the transfer mechanism 300. The axes of each insertion portion 510 of the connector 500 are parallel to the horizontal direction, corresponding one-to-one with each second fixture 200. A gap exists between the inner wall of the clearance hole 410 and the first fixture 100, allowing the first fixture 100 to move towards each of the second fixtures 200.

[0075] With the above structure, the table surface of the platform 400 is clean and spacious, which is convenient for operators to load and unload materials; the transfer mechanism 300 and the operating area above the platform 400 are isolated by the platform 400, which improves the safety of operation and allows operators to observe the insertion process more intuitively, which is convenient for visual quality inspection and quick detection of abnormalities.

[0076] The working process of this automatic cannulation machine is as follows: Taking a T-type tee connector as an example, the transfer mechanism 300 drives the first fixture 100 to move to the initial position. In the initial position, the operator places the connector 500 to be inserted into the first positioning groove 111 and drives the first clamping structure 120 to press against the connector 500. The operator then places the tubing 600 into the second fixture 200 in sequence, and the second clamping structure 220 presses against the tubing 600. Next, the first transfer module 310 drives the first fixture 100 to move to the first insertion position, so that one insertion part 510 of the connector 500 is inserted into the corresponding tubing 600. Then, the second fixture 200, which contains the tubing 600, releases the tubing 600. The first transfer module 310 drives the first fixture 100 to move to the first insertion position. In the second insertion position, another insertion portion 510 of the connector 500 is inserted into the corresponding hose 600, and then the second fixture 200 containing the hose 600 releases the hose 600; the first transfer module 310 drives the first fixture 100 to move to the initial position; then the second transfer module 320 drives the first fixture 100 to move to the third insertion position, so that the remaining insertion portion 510 of the connector 500 is inserted into the corresponding hose 600, and then the second fixture 200 containing the hose 600 releases the hose 600; the second transfer module 320 drives the first fixture 100 to move to the initial position, and the operator drives the first clamping structure 120 to release the connector 500 and remove the connector 500 and each hose 600 inserted into the connector 500.
