[0002] Cleaning equipment typically has internal connecting pipes to form a liquid loop, which delivers clean water or wastewater to a predetermined location within the cleaning equipment. Liquid loops are usually quite long, requiring the use of various pipe fittings to connect multiple pipes together.

[0003] In existing technologies, the cannulation process for cleaning equipment mainly relies on manual operation. Manual cannulation not only requires a large amount of labor but is also very time-consuming and has high production costs. Furthermore, it is difficult for different operators to control the cannulation depth within a standardized range, resulting in inconsistent cannulation quality and hindering standardized operations. Therefore, it is necessary to improve the existing technology to overcome these shortcomings. Utility Model Content

[0033] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0034] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0035] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0036] like Figure 1 and Figure 2 As shown, this utility model provides a tube insertion device for inserting a flexible tube 900 into the connector 911 of a workpiece 910. In one application scenario, the tube insertion device is suitable for tube insertion operations between the flexible tube 900 in a sweeping machine and the workpiece 910 to be installed, realizing automated or semi-automated installation between the flexible tube 900 and the workpiece 910.

[0037] The hose 900 has an internal channel for conveying liquid. The workpiece 910 can be various pipe fittings, such as tee fittings, two-way fittings, etc. The workpiece 910 has at least one insertion end 911. The hose 900 can be inserted into the insertion end 911 through the insertion device, thereby replacing the manual insertion work, which can effectively save labor costs and improve work efficiency.

[0038] The application scenarios of the insertion device are not limited to the insertion of the flexible hose 900 of a sweeper; it can also be applied to other fields with flexible hose insertion requirements. It is worth noting that the insertion device is not limited to the insertion of the flexible hose 900; it can also be used for the insertion of rigid pipes. The following description uses the insertion of the flexible hose 900 as an example, but based on the above description, the scope of protection of this utility model is not limited thereto.

[0039] The cannulation device includes a base 100 and a clamping drive assembly 200. The base 100 holds a workpiece 910 (pipe connector), which can be fixed relative to the base 100 under external force. The purpose of this "external force" is to prevent the workpiece 910 from changing position during the cannulation operation, thus ensuring the smooth insertion of the flexible tube 900 onto the workpiece 910.

[0040] The aforementioned “external force” is preferably the force applied to the workpiece 910 by an external mechanism. Of course, the aforementioned “external force” is not limited to the force applied to the workpiece 910 by an external mechanism. It can also be the force applied to the workpiece 910 by the operator’s hand, that is, the operator directly presses the workpiece 910 with his hand.

[0041] In this embodiment of the present disclosure, a pressure block assembly 800 is disposed next to the base 100. The pressure block assembly 800 is used to provide an external force to fix the workpiece 910 to the base 100. The pressure block assembly 800 includes at least a pressure block 810, which has at least a pressing position abutting above the workpiece 910. In the pressing position, the workpiece 910 is constrained between the base 100 and the pressure block 810. At this time, the workpiece 910 is fixed relative to the base 100, and the operable flexible hose 900 is inserted into the connector 911 of the workpiece 910. Preferably, the pressure block 810 is located directly above the workpiece 910.

[0042] In one embodiment, the pressure block 810 is capable of moving up and down. The pressure block assembly 800 also includes a linear drive 820 that drives the pressure block 810 to move up and down. The pressure block 810 is connected to the linear drive 820, thereby driving the pressure block 810 to move up and down. Further, the pressure block 810 and the output end of the linear drive 820 are connected by a connector 830.

[0043] The pressure block 810 and the connector 830 are detachably connected. Alternatively, the pressure block 810 and the connector 830 can be fixedly connected, forming a single component. This reduces the number of parts and facilitates installation.

[0044] Furthermore, such as Figure 4As shown, the top of the pressure block 810 is recessed to form a mounting groove 811, and the connection portion between the connector 830 and the pressure block 810 is located within the mounting groove 811. By setting the mounting groove 811, not only can the connector 830 be installed and positioned, but the vertical dimension can also be reduced to a certain extent, making the entire structure more compact. Furthermore, the bottom of the pressure block 810 has a downwardly protruding abutment portion 812, and the bottom surface of the abutment portion 812 contacts the workpiece 910.

[0045] Preferably, the pressure block 810 and the connector 830 are connected by bolts, and the pressure block 810 can be removed from the connector 830. This facilitates replacement of the pressure block 810 when it becomes worn or damaged. Furthermore, the material of the pressure block 810 is different from that of the connector 830. Specifically, the pressure block 810 is made of nylon or hard rubber, while the connector 830 is made of metal. Nylon or hard rubber is softer than metal, and when mating with the workpiece 910, the pressure block 810 made of nylon or hard rubber is less likely to abrade the surface of the workpiece 910, preventing scratches on the surface of the workpiece 910.

[0046] In addition to a downward pressing position abutting above the workpiece 910, the pressure block 810 also has at least a lifting position that moves upward away from the workpiece 910. When the pressure block 810 is in the lifting position, there is a gap between the workpiece 910 and the pressure block 810 in the vertical direction, wherein the gap is greater than the height of the workpiece 910 itself in the vertical direction, thereby allowing the workpiece 910 to be removed from the base 100 through the space above.

[0047] In another embodiment, the pressure block 810 is rotatably configured and has a pressing position and an offset position. When the pressure block 810 rotates to be directly above the workpiece 910 and abuts against the workpiece 910, the pressure block 810 is in the pressing position. When the projection of the pressure block 810 and the workpiece 910 located below it in the vertical direction does not overlap, the pressure block 810 is in the offset position.

[0048] Whether the pressure block 810 is set by rotation or by lifting up and down, the purpose is to press the workpiece 910 onto the base 100, so that the workpiece 910 has a fixed position relative to the base 100, preventing the workpiece 910 from changing position due to force during the tube insertion process, thus affecting the tube insertion operation.

[0049] In the embodiments disclosed herein, such as Figure 5 As shown, the top of the base 100 is provided with a groove 110 that mates with the workpiece 910. At least a portion of the insertion end 911 extends to the outside of the groove 110 to facilitate the insertion of the flexible hose 900. The top of the base 100 is also provided with a clearance groove 120, located around the periphery of the groove 110, for clearance of structures on the workpiece 910 or for clearance of the clamping drive assembly 200, etc.

[0050] The clamping drive assembly 200 is located on one side of the base 100. The clamping drive assembly 200 is capable of clamping the hose 900 and driving the hose 900 toward the connector 911. Figure 2 and Figure 3 As shown, the clamping drive assembly 200 is provided with clamping holes 212 for the hose 900 to pass through. When the hose 900 is clamped, both ends of the hose 900 are located outside the clamping holes 212 and at both ends in the axial direction of the clamping holes 212.

[0051] After the hose 900 is clamped, the hose 900 is divided into three parts, as follows: Figure 6 As shown, the first part 901 is the proximal portion near the connector end 911, the second part 902 is the middle portion surrounded by the clamping hole 212, and the third part 903 is the remaining distal portion of the hose 900. The axial length of the first part 901 is less than the axial length of the third part 903. Furthermore, the axial length of the first part 901 is less than the axial length of the second part 902, and the axial length of the second part 902 is less than the axial length of the third part 903.

[0052] In this embodiment of the present disclosure, the clamping hole 212 is coaxially arranged with the insertion end 911 at least near the insertion end 911. The advantage of ensuring coaxiality is that during the insertion process, only the horizontal movement of the flexible tube 900 is needed to achieve the automatic insertion action of the flexible tube, which can replace manual insertion. This can effectively reduce labor input costs and improve insertion accuracy, avoid repeated alignment operations, and make insertion more convenient, faster, and more efficient.

[0053] like Figure 2 As shown, the clamping drive assembly 200 includes at least a clamping unit 210, which includes at least a pair of clamping blocks 211 that can approach or move away from each other. Each clamping block 211 has a clamping groove extending along the insertion direction (axial direction). The pair of clamping blocks 211 are symmetrically arranged. When the pair of clamping blocks 211 abut against each other, the pair of clamping grooves can form a clamping hole 212. The term "axial direction" as used below refers to the axial direction of the clamping hole 212 or the axial direction of the hose 900.

[0054] Considering that the shape of the hose 900 changes after being clamped, in this embodiment, the clamping hole 212 is configured with a variable diameter; that is, the diameter of the clamping hole 212 varies in the axial direction. Specifically, as shown... Figure 8 As shown, the clamping hole 212 has at least an axially distributed flared section 213 and a clamping section 214, the flared section 213 and the clamping section 214 are adjacent to each other and connected, and the flared section 213 is distributed closer to the insertion end 911 than the clamping section 214.

[0055] Preferably, the flared section 213 is a tapered hole with a gradually increasing diameter along the direction from the clamping drive assembly 200 to the insertion end 911, wherein the tapered hole is coaxially distributed with the insertion end 911, and the diameter of the flared section 213 is slightly larger than the outer diameter of the hose 900. Here, "the diameter of the flared section 213" refers to the minimum diameter of the tapered hole.

[0056] like Figure 6 As shown, the hose 900 is cylindrical in shape when not subjected to external force. When a pair of clamping blocks 211 abut against each other, the portion of the hose 900 corresponding to the clamping section 214 is clamped and deformed under the action of the clamping blocks 211, changing from its original cylindrical state to a flattened cylindrical shape. The area immediately adjacent to the flattened cylindrical region (the area opposite to the flared section 213 in the second part 902) is also stretched to form a gently sloping shape, such as... Figure 7 As shown.

[0057] From a force perspective, the clamping force applied to the hose 900 by the clamping section 214 is gradually transmitted and dispersed to both sides through the hose 900 itself. The closer to the clamping point, the greater the indirect force; the farther away, the smaller the force. To maintain its continuity, the hose 900 smoothly transitions from "flat" to "circular". In this embodiment, by setting the flared section 213 in a conical shape, it can adapt to the aforementioned deformation trend of the second part 902.

[0058] It is worth noting that when the hose 900 is clamped by the clamping drive assembly 200, the portion of the hose 900 located in the clamping section 214 is enclosed within the clamping section 214, and the wall of the portion of the hose 900 located in the clamping section 214 abuts against the wall of the hole in the clamping section 214. In other words, when a pair of clamping blocks 211 abut against each other, the area of ​​the hose 900 corresponding to the clamping section 214 is completely within the clamping hole 212, with no part exceeding the receiving area of ​​the clamping hole 212. This effectively prevents the hose 900 from being clamped outside the clamping section 214 and prevents the clamping blocks 211 from damaging the hose 900.

[0059] In the embodiments disclosed herein, such as Figure 3 and Figure 8 As shown, the clamping section 214 is a through hole with an elliptical or eye-shaped cross-section. The aforementioned "cross-section" refers to a cross-section perpendicular to the axial direction of the clamping hole 212. The clamping section 214 has the above-mentioned shape, which can better adapt to the deformation of the hose 900 and ensure that it holds the hose 900 while preventing excessive clamping force from damaging the hose 900.

[0060] Regarding the structure of the clamping groove, such as Figure 8As shown, along the axial direction of the clamping hole 212, the clamping groove includes adjacently distributed first section N and second section M. A pair of first sections N are arranged to form a flared section 213 when a pair of clamping blocks 211 are in contact, and a pair of second sections M are arranged to form a clamping section 214 when a pair of clamping blocks 211 are in contact.

[0061] The second section M is an arc-shaped surface with a radius larger than that of the hose 900. This is designed so that when the hose 900 is clamped, its shape changes from a cylindrical shape to a flattened cylindrical shape. The major axis of the flattened cylindrical shape is larger than the diameter of the hose 900. Therefore, the radius of the second section M needs to be larger than the radius of the hose 900 to ensure that the hose 900 at the clamping point can be completely contained within the through hole of the clamping section 214.

[0062] In this embodiment, the outer contour dimension of the region where the first segment N is formed on the clamping block 211 is smaller than the outer contour dimension of the region where the second segment M is formed on the clamping block 211. When a pair of clamping blocks 211 abut against each other, the region where the clamping hole 212 is formed on the clamping block 211 has a "convex" shaped structure in the horizontal direction.

[0063] like Figure 9 As shown, the base 100 and the clamping drive assembly 200 are mounted on the worktable 300. The base 100 and the clamping drive assembly 200 can be configured in a one-to-one correspondence, or one base 100 can be equipped with multiple clamping drive assemblies 200. For example, when the workpiece 910 is a tee pipe connector, it has three insertion ends 911. In this case, one base 100 can be equipped with three clamping drive assemblies 200. Of course, when the workpiece 910 has multiple insertion ends 911, one base 100 can be configured with one clamping drive assembly 200. In this case, a transfer mechanism (not shown) is required to change the position of the clamping drive assembly 200 so that it can be inserted with different insertion ends 911 on the workpiece 910.

[0064] In this embodiment, a limiting structure 500 is provided between the clamping drive assembly 200 and the worktable 300. The limiting structure 500 is configured such that the projections of the insertion end 911 and the clamping hole 212 on the worktable 300 lie on the extension of the same straight line. That is, the limiting structure 500 can limit the clamping hole 212 and the insertion end 911 in the horizontal direction, thereby effectively reducing the adjustment mechanisms (e.g., various linear drive mechanisms, rotary drive mechanisms) used to adjust the horizontal position of the clamping hole 212 and the insertion end 911.

[0065] Furthermore, the limiting structure 500 includes at least a pair of pins 510 and a pair of pin holes 520 that mate with the pair of pins 510. One of the pins 510 and the pin holes 520 is located on the worktable 300, and the other is located on the bottom of the clamping drive assembly 200.

[0066] In this embodiment of the disclosure, a first adjustment structure 600 is further provided between the clamping drive assembly 200 and the worktable 300. The first adjustment structure 600 is configured to adjust the distance between the clamping drive assembly 200 and the base 100 based on the limitation of the limiting structure 500.

[0067] like Figure 9 As shown, the first adjustment structure 600 includes at least an oblong hole 610 on the clamping drive assembly 200 and an adjusting bolt (not shown) inserted into the oblong hole 610. The worktable 300 also has a screw hole 620 that mates with the adjusting bolt. The length of the oblong hole 610 determines the adjustable distance of the first adjustment structure 600. The oblong hole 610 and the pin hole 520 are distributed parallel to each other, and the projection of the screw hole 620 in the vertical direction is located within the oblong hole 610. It is worth noting that the pin hole 520 is an elongated hole to cooperate with the oblong hole 610 for adjusting the position of the clamping drive assembly 200 on the worktable 300.

[0068] In this embodiment, a second adjustment structure 700 is provided between the clamping drive assembly 200 and the worktable 300. The second adjustment structure 700 is placed between the clamping drive assembly 200 and the worktable 300 to adjust the height of the clamping hole 212 in the vertical direction. Thus, under the limiting and adjusting action of the limiting structure 500 and the second adjustment structure 700, the clamping hole 212 can ensure the coaxiality requirement with the insertion end 911. This mechanical adjustment method helps reduce manufacturing costs, is simple to operate, requires little operator expertise, and is convenient to use. Preferably, the second adjustment structure 700 is at least one horizontally extending adjustment plate. (See attached...) Figure 9 As shown, an adjustment plate is provided below the clamping drive assembly 200, and the height of the clamping drive assembly 200 is adjusted by adjusting the adjustment plate. The limiting structure 500 is located between the second adjustment structure 700 and the worktable 300.

[0069] Regarding the clamping drive assembly 200, the clamping drive assembly 200 also includes a drive unit 220 that drives a pair of clamping blocks 211 to perform linear reciprocating motion. The clamping unit 210 is connected to the drive unit 220. Under the action of the drive unit 220, the clamping unit 210 can perform linear reciprocating motion to move closer to or away from the connector end 911. Furthermore, the insertion depth of the hose 900 on the connector end 911 can be adjusted by controlling the movement stroke of the drive unit 220, thereby helping to ensure the insertion accuracy of the tube.

[0070] In this embodiment, the clamping unit 210 further includes a gripper cylinder 212. A pair of gripping blocks 211 are disposed on a pair of output ends of the gripper cylinder 212, and the gripper cylinder 212 enables the pair of gripping blocks 211 to move closer to or further away from each other. The gripper cylinder 212 is disposed on the output end of the drive unit 220, and the drive unit 220 drives the gripper cylinder 212 to perform linear reciprocating motion.

[0071] In one embodiment, the drive unit 220 is disposed on the worktable 300 via a second adjustment structure 700, which is pressed between the drive unit 220 and the worktable 300. The drive unit 220 is mounted on the second adjustment structure 700. A limiting structure 500 and a first adjustment structure 6000 are disposed between the second adjustment structure 700 and the worktable 300. Specifically, a pin 510 is fixed to the worktable 300, and a pin hole 520 and a slotted hole 610 are provided on the second adjustment structure 700.

[0072] like Figure 2 and Figure 9 As shown, the cannulation device further includes a support 400 for supporting the third part 903 of the flexible tube 900. The support 400 has a groove 410 defining the position of the flexible tube 900; preferably, the groove 410 and the clamping hole 212 are located on the extension of the same straight line. The clamping hole 212 is located between the support 400 and the base 100.

[0073] When a pair of clamping blocks 211 abut against each other, the connection between the second part 902 and the third part 903 of the hose 900 will deform. This deformation can easily cause bending at the connection between the second part 902 and the third part 903, resulting in creases on the hose 900, which is undesirable. The support 400 effectively prevents unnecessary creases from forming on the third part 903, providing a certain degree of protection for the hose 900.

[0074] The workbench 300 is also equipped with a touch screen display unit 310, which allows the operator to control the entire machine. In other words, the operator can control the clamping drive assembly 200, linear drive component 820 and other electrical components to work according to instructions through the touch screen display unit 310, which effectively improves the automation level of the cannulation operation.

[0075] During use, the operator places the workpiece 910 to be inserted into the groove 110 on the top of the base 100; then controls the linear drive 820 to drive the pressure block 810 down, so that the workpiece 910 is fixed relative to the base 100; next, the clamping unit 210 clamps the hose 900, and the drive unit 220 drives the hose 900 toward the insertion end 911 until the end of the first part 901 of the hose 900 is inserted into the insertion end 911, thereby realizing the insertion operation.

[0076] In this embodiment of the disclosure, the cooperation between the base 100 and the clamping drive assembly 200 enables the automatic insertion of the hose 900, replacing manual insertion. This effectively reduces labor input costs and improves insertion efficiency while also reducing the discomfort (fatigue) caused by frequent manual insertion by workers, which is conducive to achieving standardized insertion operations.

[0077] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
