Description

Technical Field

[0001] This invention relates to the field of rubber hose and connector assembly technology in semiconductor manufacturing and related fluid transport systems, and specifically to an automatic hose reel installation device. Background Technology

[0002] In semiconductor manufacturing and related fluid transport systems, braided rubber hoses (hereinafter referred to as rubber hoses) are critical connecting components. The reliability of the joints at both ends directly affects system stability, sealing performance, and production efficiency. During semiconductor manufacturing, fluid transport systems (such as coolant and chemical supply) place extremely high demands on the sealing performance of rubber hose joints (the joints at both ends of the rubber hose are generally directly inserted into the hose ends, and the joints and hoses are press-fitted together to achieve a sealed connection). Even minor leaks at the joints at both ends of the rubber hose can lead to product contamination; chemical leaks can contaminate wafers or equipment, causing significant economic losses. They can also cause system downtime, requiring maintenance and increasing unplanned downtime, reducing production efficiency. Furthermore, there may be safety hazards, such as injuries to operators from leaks of certain fluids (e.g., corrosive liquids).

[0003] Traditional rubber hose connector installation is done manually. For example, Chinese Patent Publication No. CN207788833U, entitled "Installation Device for Rubber Hose and Quick Connector," includes a base with a mounting plate. A fixing block and a shaping block are fixedly connected to the mounting plate. A quick connector for connecting to the rubber hose is mounted on the fixing block, and a contoured groove for placing the rubber hose is provided on the upper surface of the shaping block. In this application, the rubber hose and quick connector are also manually connected. Manual installation of rubber hose connectors has the following drawbacks. The work is labor-intensive, requiring operators to manually insert the connector into the end of the rubber hose. Due to the interference fit between the connector and the rubber hose to achieve a sealed connection, a large insertion force is required when inserting the connector into the rubber hose. This labor-intensive and repetitive work over a long period of time can easily lead to fatigue and affect the installation accuracy.

[0004] Quality fluctuations can affect the installation quality of the connectors. Manual operation may result in uneven force and failure to ensure the coaxial insertion of the connector and the rubber hose during the insertion process, leading to poor sealing between the connector and the rubber hose, or even damage to the hose, which in turn can cause leakage risks.

[0005] The connector installation is inefficient, and the speed of manual installation is limited by the operator's skill level, making it difficult to meet the strict cycle time requirements of large-scale production in the semiconductor industry. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic pipe installation device that can not only effectively improve the installation efficiency of rubber hoses and connectors and reduce labor intensity, but also effectively improve the installation quality of connectors and effectively avoid the problem of poor sealing between the connector and rubber hose, or even damage to the hose, and thus cause leakage risk, due to the inability to ensure the coaxial insertion state of the connector and rubber hose during the insertion process.

[0007] The technical solution of this invention is: An automatic take-off and installation device includes: Base; The hose positioning assembly includes a lower positioning seat on a base, an upper pressure seat above the lower positioning seat, and a lifting actuator for driving the upper pressure seat to rise and fall. The top surface of the lower positioning seat is provided with a semi-circular lower limit through groove, and the bottom surface of the upper pressure seat is provided with a semi-circular upper limit through groove. The connector positioning and pressing assembly includes a connector positioning component and a translational actuator that drives the connector positioning component to move axially along the lower limit through groove. The connector positioning component has a positioning hole coaxial with the lower limit through groove at one end facing the lower positioning seat. The specific use of an automatic pipe installation device according to this solution is as follows. For connector positioning and installation, insert one end of the connector into the positioning hole of the connector positioning component until the connector abuts against the end of the positioning hole. At this point, the connector and the positioning hole are coaxially distributed.

[0008] For rubber hose positioning and installation, place the end of the rubber hose into the lower limit through groove, ensuring the end face of the rubber hose is flush with the end of the lower limit through groove facing the connector positioning component. The inner diameter of the lower limit through groove matches the outer diameter of the rubber hose. Then, the lifting actuator lowers the upper pressure seat until its bottom surface abuts against the top surface of the lower positioning seat. At this point, the rubber hose is pressed into the circular limiting through hole formed by the lower and upper limit through grooves, with an interference fit between the circular limiting through hole and the rubber hose. Since the positioning holes of the connector and the connector positioning component are coaxially distributed, and the positioning holes are coaxial with the lower limit through groove, and the end of the rubber hose is pressed between the lower and upper limit through grooves, the coaxiality of the rubber hose end with the lower limit through groove is equivalent to the connector and the rubber hose end pressed between the lower and upper limit through grooves being coaxially distributed.

[0009] The connector insertion and installation process involves a translational actuator that moves the connector positioning component and the connector a set distance towards the lower positioning seat, inserting the connector into the port of the rubber hose until the shoulder of the connector abuts against the end face of the rubber hose. During this process, the thrust exerted on the connector by the translational actuator is uniform, and the connector and the end of the rubber hose, which is pressed between the lower and upper limit through grooves, are coaxially distributed. This ensures the quality of connector installation and effectively avoids problems such as poor sealing between the connector and the rubber hose, or even hose damage and leakage risks, caused by incomplete coaxial insertion during the insertion process. Furthermore, this system enables automatic insertion and installation of connectors and rubber hoses, effectively improving installation efficiency and reducing manual labor intensity.

[0010] Preferably, the hose positioning assembly further includes a floating positioning device, comprising: A floating plate, perpendicular to the axis of the lower limit through groove, is slidably mounted on the side of the lower positioning seat facing the joint positioning component. A spring drives the floating plate to move upward and block one end of the lower limit through slot; The push rod is fixedly mounted on the upper pressure seat and located on one side of the upper limit slot; When the bottom surface of the upper pressure seat abuts against the top surface of the lower positioning seat, the push rod abuts against the floating plate and moves the floating plate downwards to below the lower limit through groove. Since the connector needs to be positioned so that its shoulder rests against the end face of the rubber hose when inserted into the port of the rubber hose, the operator must adjust the position of the rubber hose after placing its end in the lower limit through groove so that its end face is flush with the end of the lower limit through groove facing the connector positioning component during the subsequent connector insertion and installation steps. This ensures that the connector's shoulder rests precisely against the end face of the rubber hose when the translation actuator moves the connector positioning component and the connector a set distance towards the lower positioning seat. However, during actual installation, due to the lack of a positioning structure at the end of the lower limit groove, the end face of the rubber hose is prone to misalignment with the end of the lower limit groove facing the connector positioning element. For example, if the end face of the rubber hose extends beyond the lower limit groove, during the subsequent connector insertion and installation step, when the translation actuator moves the connector positioning element and the connector a set distance towards the lower positioning seat, the shoulder of the connector may squeeze the end face of the rubber hose, causing damage to the end of the rubber hose and leading to leakage risk. Alternatively, if the end face of the rubber hose is located within the lower limit groove, during the subsequent connector insertion and installation step, when the translation actuator moves the connector positioning element and the connector a set distance towards the lower positioning seat, a gap may appear between the shoulder of the connector and the end face of the rubber hose, resulting in incomplete connector insertion and requiring rework. To solve these problems, this solution incorporates a floating positioning device, which can position the hose end face without affecting the connector insertion and installation, ensuring that the end face of the rubber hose is flush with the end of the lower limit groove facing the connector positioning element, thus effectively solving the aforementioned problems. Specifically, During the positioning and installation of the rubber hose, the floating plate moves upward under the action of the spring and blocks one end of the lower limit through groove. At this time, after the end of the rubber hose is placed in the lower limit through groove, the rubber hose can be moved to press the end face of the rubber hose against the floating plate, so that the end face of the rubber hose is flush with the end of the lower limit through groove facing the connector positioning part. Next, the lifting actuator drives the upper pressure seat to descend. During this process, the push rod descends with the upper pressure seat, pressing against the floating plate and causing it to move downwards. When the bottom surface of the upper pressure seat abuts against the top surface of the lower positioning seat, the rubber hose is pressed into the circular limiting through hole formed by the lower and upper limiting through grooves. Simultaneously, the floating plate is pressed down by the push rod to below the lower limiting through groove. At this point, the floating plate does not affect the subsequent connector insertion and installation steps. This achieves the positioning of the hose end face without affecting the connector insertion and installation, ensuring that the end face of the rubber hose is flush with the end of the lower limiting through groove facing the connector positioning component. This ensures that during the connector insertion and installation steps, when the translation actuator moves the connector positioning component and the connector a set distance towards the lower positioning seat, the connector shoulder is precisely abutting against the end face of the rubber hose. This effectively solves the problem of rubber hose end being squeezed and damaged due to the rubber hose end face not being flush with the end of the lower limiting through groove facing the connector positioning component, as well as the problem of incomplete connector insertion requiring rework.

[0011] Preferably, a vertical groove is provided on the side of the lower positioning seat facing the joint positioning component, and a slider is provided in the vertical groove. The floating plate is fixed on the slider, and the slider abuts against the upper end of the vertical groove under the action of the spring. At this time, the floating plate blocks one end of the lower limiting through groove.

[0012] Preferably, there are two hose positioning assemblies and two connector positioning and pressing assemblies, each corresponding to one of the hose positioning assemblies. Thus, in the connector positioning and installation step, each hose positioning assembly can position one connector within its connector positioning element; in the rubber hose positioning and installation step, both ends of the rubber hose can be positioned and fixed in their respective hose positioning assemblies, achieving simultaneous positioning and fixing of both ends of a single rubber hose; in the connector insertion and installation step, the connector positioning and pressing assemblies can insert two connectors one-to-one into the two ends of the same rubber hose, further improving the installation efficiency of the rubber hose and connector.

[0013] Preferably, the two hose positioning assemblies are arranged side by side, and the axes of the lower limit through grooves of the two hose positioning assemblies are coaxial or parallel, and the two hose positioning assemblies are distributed between the two joint positioning and pressing assemblies.

[0014] Preferably, the lower positioning seat is bolted to the base, and the upper pressure seat is detachably connected to the lifting actuator. This allows for the replacement of different lower positioning seats and upper pressure seats according to the actual outer diameter of the installed rubber hose, accommodating the installation needs of rubber hoses with different outer diameters.

[0015] Preferably, the connector positioning element is detachably connected to the translation actuator. This allows for the replacement of different connector positioning elements based on the actual outer diameter of the installed connector, accommodating the installation needs of connectors with different outer diameters.

[0016] Preferably, the lifting actuator is a pneumatic cylinder, an electric cylinder, or an electric push rod.

[0017] Preferably, the translation actuator is a pneumatic cylinder, an electric cylinder, or an electric push rod.

[0018] Preferably, the hose positioning assembly further includes a mounting bracket fixed to the base, and the lifting actuator is mounted on the mounting bracket; the connector positioning and pressing assembly further includes a mounting support fixed to the base, and the translation actuator is mounted on the mounting support. This facilitates the installation of the lifting and translation actuators of the hose positioning assembly.

[0019] The beneficial effects of this invention are: Firstly, it enables automatic insertion and installation of connectors and rubber hoses, thereby effectively improving the installation efficiency of rubber hoses and connectors and reducing manual labor intensity.

[0020] Secondly, during the insertion of the connector into the end of the rubber hose, it can ensure that the connector thrust is uniform and that the connector and the end of the rubber hose are coaxially distributed, thereby ensuring the installation quality of the connector and effectively avoiding the problem of poor sealing between the connector and the rubber hose, or even damage to the hose, due to the inability to ensure the coaxial insertion state of the connector and the rubber hose during the insertion process.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Specific Implementation Example 1, such as Figure 1 As shown, an automatic pipe installation device includes a base 1, a hose positioning assembly 2, and a connector positioning and pressing assembly 3.

[0027] The hose positioning assembly 2 includes a lower positioning seat 2.1 mounted on a base 1, an upper pressure seat 2.2 located above the lower positioning seat 2.1, and a lifting actuator 2.3 for driving the upper pressure seat 2.2 to rise and fall. The lifting actuator 2.3 is mounted on the base 1. The lifting actuator 2.3 is a pneumatic cylinder, an electric cylinder, or an electric push rod 4.3. A semi-circular lower limit through-slot 2.4 is provided on the top surface of the lower positioning seat 2.1. The opening of the lower limit through-slot 2.4 faces upward and penetrates the top surface of the lower positioning seat 2.1. A semi-circular upper limit through-slot 2.5 is provided on the bottom surface of the upper pressure seat 2.2. The opening of the upper limit through-slot 2.5 faces downward and penetrates the bottom surface of the upper pressure seat 2.2. The upper limit through-slot 2.5 is located directly above the lower limit through-slot 2.4, and the axial direction of the upper limit through-slot 2.5 is parallel to the axial direction of the lower limit through-slot 2.4.

[0028] When the bottom surface of the upper pressure seat 2.2 abuts against the top surface of the lower positioning seat 2.1, the lower limit through groove 2.4 and the upper limit through groove 2.5 together form a circular limit through hole.

[0029] The connector positioning and pressing assembly 3 includes a connector positioning element 3.1 and a translational actuator 3.2 that drives the connector positioning element 3.1 to move axially along the lower limit through groove 2.4. The connector positioning element 3.1 has a positioning hole 3.3 at one end facing the lower positioning seat 2.1, and the positioning hole 3.3 is coaxially distributed with the lower limit through groove 2.4. The translational actuator 3.2 is mounted on the base 1. The translational actuator 3.2 is a pneumatic cylinder, an electric cylinder, or an electric push rod 4.3.

[0030] The specific use of the automatic pipe connection installation device in this embodiment is as follows. For connector positioning and installation, insert one end of the connector into the positioning hole 3.3 of the connector positioning part 3.1 until the connector abuts against the end of the positioning hole 3.3. At this time, the connector and the positioning hole 3.3 are coaxially distributed.

[0031] For positioning and installation of the rubber hose, place the end of the rubber hose into the lower limit through groove 2.4, and make the end face of the rubber hose flush with the end of the lower limit through groove 2.4 facing the connector positioning part 3.1. The inner diameter of the lower limit through groove 2.4 is adapted to the outer diameter of the rubber hose. Then, the lifting actuator 2.3 drives the upper pressure seat 2.2 to descend until the bottom surface of the upper pressure seat 2.2 abuts against the top surface of the lower positioning seat 2.1. At this time, the rubber hose is pressed into the circular limiting through hole formed by the lower limit through groove 2.4 and the upper limit through groove 2.5. The circular limiting through hole and the rubber hose are interference fit. Since the positioning hole 3.3 of the connector and the positioning part 3.1 are coaxially distributed, the positioning hole 3.3 is coaxial with the lower limit through groove 2.4, and the end of the rubber hose is pressed between the lower limit through groove 2.4 and the upper limit through groove 2.5, the end of the rubber hose is coaxial with the lower limit through groove 2.4, which is equivalent to the connector and the end of the rubber hose pressed between the lower limit through groove 2.4 and the upper limit through groove 2.5 being coaxially distributed.

[0032] During the connector insertion and installation, the translation actuator 3.2 moves the connector positioning component 3.1 and the connector downwards to the positioning seat 2.1 by a set distance, thereby inserting the connector into the port of the rubber hose until the shoulder of the connector abuts against the end face of the rubber hose. During this process, the thrust exerted on the connector by the translation actuator 3.2 is uniform, and the connector and the end of the rubber hose, which is pressed between the lower limit through groove 2.4 and the upper limit through groove 2.5, are coaxially distributed, thus ensuring the quality of connector installation and effectively avoiding the problem of poor sealing between the connector and the rubber hose, or even damage to the hose, and thus the risk of leakage, due to the inability to ensure the coaxial insertion state of the connector and the rubber hose during the insertion process.

[0033] Next, the translation actuator 3.2 drives the joint positioning component 3.1 to move back and reset.

[0034] The automatic pipe installation device in this embodiment can realize the automatic insertion and installation of the connector and the rubber hose, thereby effectively improving the installation efficiency of the rubber hose and the connector and reducing the intensity of manual labor.

[0035] Specific embodiment two, such as Figure 1 , Figure 2 As shown, an automatic pipe fitting installation device includes a base 1, a hose positioning assembly 2, and a connector positioning and pressing assembly 3. There are one or more hose positioning assemblies 2, and each connector positioning and pressing assembly 3 corresponds to a hose positioning assembly 2. In this embodiment, there are two hose positioning assemblies 2 and two connector positioning and pressing assemblies 3, each corresponding to a hose positioning assembly 2.

[0036] The hose positioning assembly 2 includes a lower positioning seat 2.1 mounted on a base 1, an upper pressure seat 2.2 located above the lower positioning seat 2.1, and a lifting actuator 2.3 for driving the upper pressure seat 2.2 to rise and fall. The lifting actuator 2.3 is mounted on the base 1. The lifting actuator 2.3 is a cylinder, an electric cylinder, or an electric push rod 4.3. A semi-circular lower limiting through groove 2.4 is provided on the top surface of the lower positioning seat 2.1. The opening of the lower limiting through groove 2.4 faces upward and penetrates the top surface of the lower positioning seat 2.1. In this embodiment, the axial direction of the lower limiting through groove 2.4 is horizontally distributed. A semi-circular upper limiting through groove 2.5 is provided on the bottom surface of the upper pressure seat 2.2. The upper limit through groove 2.5 has its opening facing downwards and penetrates the bottom surface of the upper pressure seat 2.2. The upper limit through groove 2.5 is located directly above the lower limit through groove 2.4, and the axial direction of the upper limit through groove 2.5 is parallel to the axial direction of the lower limit through groove 2.4.

[0037] When the bottom surface of the upper pressure seat 2.2 abuts against the top surface of the lower positioning seat 2.1, the lower limit through groove 2.4 and the upper limit through groove 2.5 together form a circular limit through hole.

[0038] The connector positioning and pressing assembly 3 includes a connector positioning element 3.1 and a translational actuator 3.2 that drives the connector positioning element 3.1 to move axially along the lower limit through groove 2.4. The connector positioning element 3.1 has a positioning hole 3.3 at one end facing the lower positioning seat 2.1, and the positioning hole 3.3 is coaxially distributed with the lower limit through groove 2.4. The translational actuator 3.2 is mounted on the base 1. The translational actuator 3.2 is a cylinder, an electric cylinder, or an electric push rod 4.3. In this embodiment, the connector positioning element 3.1 is cylindrical, and the positioning hole 3.3 is coaxially distributed with the connector positioning element 3.1. Of course, the shape of the connector positioning element 3.1 is not limited to cylindrical; it can also be square or other shapes.

[0039] The specific use of the automatic pipe connection installation device in this embodiment is as follows. For connector positioning and installation, insert one end of the connector into the positioning hole 3.3 of the connector positioning member 3.1 until the connector abuts against the end of the positioning hole 3.3. At this time, the connector and the positioning hole 3.3 are coaxially distributed. Each connector positioning member 3.1 of each hose positioning assembly 2 positions one connector in the positioning hole 3.3 (the connector has an annular convex ring in the middle, and the end face of the annular convex ring forms the shoulder of the connector).

[0040] For positioning and installation of the rubber hose, place the end of the rubber hose into the lower limit through groove 2.4, and make the end face of the rubber hose flush with the end of the lower limit through groove 2.4 facing the connector positioning part 3.1. The inner diameter of the lower limit through groove 2.4 is adapted to the outer diameter of the rubber hose. Then, the lifting actuator 2.3 drives the upper pressure seat 2.2 to descend until the bottom surface of the upper pressure seat 2.2 abuts against the top surface of the lower positioning seat 2.1. At this time, the rubber hose is pressed into the circular limiting through hole formed by the lower limit through groove 2.4 and the upper limit through groove 2.5. The circular limiting through hole and the rubber hose are interference fit. Since the positioning hole 3.3 of the connector and the positioning part 3.1 are coaxially distributed, the positioning hole 3.3 is coaxial with the lower limit through groove 2.4, and the end of the rubber hose is pressed between the lower limit through groove 2.4 and the upper limit through groove 2.5, the end of the rubber hose is coaxial with the lower limit through groove 2.4, which is equivalent to the connector and the end of the rubber hose pressed between the lower limit through groove 2.4 and the upper limit through groove 2.5 being coaxially distributed.

[0041] The two ends of the rubber hose can be positioned and fixed in a corresponding hose positioning component 2, that is, one end of the rubber hose is positioned and installed in one hose positioning component 2, and the other end of the rubber hose is positioned and installed in another hose positioning component 2, thereby realizing the positioning and fixing of both ends of a rubber hose at the same time.

[0042] During the connector insertion and installation, the translational actuator 3.2 of the connector positioning and pressing assembly 3 drives the connector positioning piece 3.1 and the connector to move a set distance towards the lower positioning seat 2.1, thereby inserting the connector into the port of the rubber hose until the shoulder of the connector abuts against the end face of the rubber hose. During this process, the thrust exerted on the connector by the translational actuator 3.2 is uniform, and the connector and the end of the rubber hose pressed between the lower limit through groove 2.4 and the upper limit through groove 2.5 are coaxially distributed, thereby ensuring the quality of connector installation and effectively avoiding the problem of poor sealing between the connector and the rubber hose, or even damage to the hose, and thus the risk of leakage, due to the inability to ensure the coaxial insertion state of the connector and the rubber hose during the insertion process.

[0043] In this embodiment, the two connector positioning and pressing components 3 insert the connectors one-to-one into the two ends of the same rubber hose, so that the connectors can be installed at both ends of the same rubber hose at the same time, thereby further improving the installation efficiency of the rubber hose and connectors.

[0044] Next, the translation actuator 3.2 of the connector positioning and pressing assembly 3 drives the connector positioning component 3.1 to move back and reset.

[0045] The automatic pipe installation device in this embodiment can realize the automatic insertion and installation of the connector and the rubber hose, thereby effectively improving the installation efficiency of the rubber hose and the connector and reducing the intensity of manual labor.

[0046] The arrangement of the two hose positioning components 2 in this embodiment can be arranged according to actual needs. Specifically, In one implementation, such as Figure 1 As shown, two hose positioning assemblies 2 are arranged side by side, sequentially distributed along the axial direction of the lower limit through groove 2.4, and the axes of the lower limit through groove 2.4 of the two hose positioning assemblies 2 are coaxially distributed. The two hose positioning assemblies 2 are distributed between the two connector positioning and pressing assemblies 3. In this way, the two hose positioning assemblies 2 and the two connector positioning and pressing assemblies 3 can be sequentially distributed along the axial direction of the lower limit through groove 2.4, reducing the space occupied by the automatic pipe installation device in the width direction of the lower limit through groove 2.4.

[0047] In another implementation, such as Figure 2 As shown, two hose positioning assemblies 2 are arranged side by side, with the axes of their lower limit through grooves 2.4 parallel to each other, and the two hose positioning assemblies 2 are sequentially distributed along the width of the lower limit through grooves 2.4. This reduces the space occupied by the automatic hose reel installation device in the axial direction of the lower limit through groove 2.4.

[0048] Furthermore, the hose positioning assembly 2 also includes a mounting bracket. The mounting bracket is fixed to the base 1 and is bolted to the base 1. The lifting actuator 2.3 is mounted on the mounting bracket. In this embodiment, the mounting bracket is a U-shaped bracket. The lifting actuator 2.3 is mounted on the top of the mounting bracket. The lower positioning seat 2.1 and the upper pressure seat 2.2 are both located inside the U-shaped bracket.

[0049] The connector positioning and pressing assembly 3 also includes a mounting bracket, which is L-shaped. The mounting bracket is bolted to the base 1. The translation actuator 3.2 is mounted on the mounting bracket. This facilitates the installation of the lifting actuator 2.3 and the translation actuator 3.2 of the hose positioning assembly 2.

[0050] Furthermore, the lower positioning seat 2.1 is bolted to the base 1. The upper pressure seat 2.2 is detachably connected to the lifting actuator 2.3. Specifically, the upper pressure seat 2.2 is bolted or threaded to the piston rod end of the cylinder, electric cylinder, or electric push rod 4.3 constituting the lifting actuator 2.3. In this way, different lower positioning seats 2.1 and upper pressure seats 2.2 can be replaced according to the actual outer diameter of the installed rubber hose to adapt to the installation needs of rubber hoses with different outer diameters.

[0051] The connector positioning element 3.1 is detachably connected to the translation actuator 3.2. Specifically, the connector positioning element 3.1 is connected to the piston rod end of the cylinder, electric cylinder, or electric push rod 4.3 constituting the translation actuator 3.2 by bolts or threads. In this way, different connector positioning elements 3.1 can be replaced according to the outer diameter of the actual installed connector to meet the installation needs of connectors with different outer diameters.

[0052] In this specific embodiment, the remaining structure is the same as in specific embodiment one or specific embodiment two, except that... like Figure 3 , Figure 4 As shown, the hose positioning assembly 2 also includes a floating positioning device 4. The floating positioning device 4 is used to position the hose end face. The floating positioning device 4 includes a floating plate 4.1, a spring 4.2, and a push rod 4.3.

[0053] The floating plate 4.1 is perpendicular to the axis of the lower limiting through groove 2.4. The floating plate 4.1 is slidably disposed on the side of the lower positioning seat 2.1 facing the connector positioning member 3.1. In this embodiment, the side of the floating plate 4.1 facing the positioning seat is a positioning surface, which is a vertical surface. The side of the lower positioning seat 2.1 facing the connector positioning member 3.1 is also a vertical surface, and the positioning surface is close to the side of the lower positioning seat 2.1 facing the connector positioning member 3.1.

[0054] Spring 4.2 drives floating plate 4.1 to move upward and block one end of lower limit through slot 2.4.

[0055] The push rod 4.3 is fixedly mounted on the upper pressure seat 2.2, and is located on one side of the upper limit through groove 2.5. In this embodiment, the push rod 4.3 is vertically distributed.

[0056] When the bottom surface of the upper pressure seat 2.2 abuts against the top surface of the lower positioning seat 2.1, the push rod 4.3 abuts against the floating plate 4.1 and moves the floating plate 4.1 downward to below the lower limit through groove 2.4.

[0057] In this embodiment, a vertical groove 4.5 is provided on the side of the lower positioning seat 2.1 facing the connector positioning member 3.1, and a slider 4.4 is provided inside the vertical groove 4.5. A floating plate 4.1 is fixed on the slider 4.4, and a spring 4.2 is located inside the vertical groove 4.5. The lower end of the spring 4.2 abuts against the lower end of the vertical groove 4.5, and the upper end of the spring 4.2 abuts against the slider 4.4. Under the action of the spring 4.2, the slider 4.4 abuts against the upper end of the vertical groove 4.5. At this time, the floating plate 4.1 blocks one end of the lower limiting through groove 2.4.

[0058] There are one or more push rods 4.3. In this embodiment, there are two push rods 4.3, and the two push rods 4.3 are symmetrically distributed on both sides of the upper limit through groove 2.5. The top two sides of the floating plate 4.1 are provided with outwardly extending portions 4.6, and the push rods 4.3 are located above the corresponding outwardly extending portions 4.6. When the lifting actuator 2.3 drives the upper pressure seat 2.2 to descend, during this process, the two push rods 4.3 descend with the upper pressure seat 2.2, and push against the floating plate 4.1 through the two push rods 4.3 and push the floating plate 4.1 to move downward, thereby ensuring that the floating plate 4.1 moves downward smoothly.

[0059] When the connector is inserted into the port of the rubber hose, it is necessary to control the shoulder of the connector to abut against the end face of the rubber hose. Therefore, in the rubber hose positioning and installation step, the operator is required to place the end of the rubber hose into the lower limit through groove 2.4 and then adjust the position of the rubber hose so that the end face of the rubber hose is flush with the end of the lower limit through groove 2.4 facing the connector positioning member 3.1. In this way, in the subsequent connector insertion and installation step, when the translation actuator 3.2 moves the connector positioning member 3.1 and the connector to the lower positioning seat 2.1 by a set distance, it can be ensured that the shoulder of the connector is exactly abutting against the end face of the rubber hose. However, during actual installation, due to the lack of a positioning structure at the end of the lower limit through groove 2.4, the end face of the rubber hose is prone to misalignment with the end of the lower limit through groove 2.4 facing the connector positioning component 3.1. For example, if the end face of the rubber hose extends beyond the lower limit through groove 2.4, during the subsequent connector insertion and installation step, when the translation actuator 3.2 moves the connector positioning component 3.1 and the connector downwards to the positioning seat 2.1 a set distance, the shoulder of the connector may squeeze the end face of the rubber hose, causing damage to the end of the rubber hose and potentially leading to leakage. Alternatively, if the end face of the rubber hose is located within the lower limit through groove 2.4, during the subsequent connector insertion and installation step, when the translation actuator 3.2 moves the connector positioning component 3.1 and the connector downwards to the positioning seat 2.1 a set distance, a gap may appear between the shoulder of the connector and the end face of the rubber hose, resulting in incomplete connector insertion and requiring rework. To address the aforementioned issues, this solution incorporates a floating positioning device 4. This device positions the hose end face without affecting the connector insertion and installation, ensuring that the rubber hose end face is flush with the end of the lower limit groove 2.4 facing the connector positioning element 3.1, thus effectively resolving the problem. Specifically, During the positioning and installation of the rubber hose, the floating plate 4.1 moves upward under the action of the spring 4.2 and blocks one end of the lower limit through groove 2.4. At this time, after the end of the rubber hose is placed in the lower limit through groove 2.4, the rubber hose can be moved to press the end face of the rubber hose against the floating plate 4.1, so that the end face of the rubber hose is flush with the end of the lower limit through groove 2.4 facing the connector positioning part 3.1. Next, the lifting actuator 2.3 drives the upper pressure seat 2.2 to descend. During this process, the push rod 4.3 descends with the upper pressure seat 2.2, and the push rod 4.3 will abut against the floating plate 4.1, causing the floating plate 4.1 to move downward. When the bottom surface of the upper pressure seat 2.2 abuts against the top surface of the lower positioning seat 2.1, the rubber hose is pressed into the circular limiting through hole formed by the lower limiting through groove 2.4 and the upper limiting through groove 2.5. At the same time, the floating plate 4.1 is pressed down by the push rod 4.3 to below the lower limiting through groove 2.4. At this time, the floating plate 4.1 does not affect the subsequent connector insertion and installation steps; thus, it achieves the goal of not affecting the connector insertion and installation. Positioning the hose end face ensures that the end face of the rubber hose is flush with the end of the lower limit through groove 2.4 facing the connector positioning piece 3.1. This ensures that during the connector insertion and installation process, when the translation actuator 3.2 moves the connector positioning piece 3.1 and the connector downwards to the positioning seat 2.1 a set distance, the shoulder of the connector is precisely against the end face of the rubber hose. This effectively solves the problem of the rubber hose end being squeezed and damaged due to the end face of the rubber hose not being flush with the end of the lower limit through groove 2.4 facing the connector positioning piece 3.1, as well as the problem of the connector not being properly inserted and requiring rework.
