Description

Technical Field

[0001] This invention relates to the field of assembly equipment technology, and in particular to a quick tightening device for electromechanical installation. Background Technology

[0002] A gas pressure reducing valve is a device used to control gas pressure. Its main function is to reduce the pressure of high-pressure gas to the required low-pressure level to ensure the stable operation and safe operation of the system. It is widely used in industrial and aerospace fields.

[0003] Common gas pressure reducing valves include valve seats, valve cores, instrument panels, inlet connectors, and outlet connectors. When assembling these parts, machining fixtures are required. For example, Chinese patent CN219599431U discloses a machining fixture for an air pressure reducing valve. When using this fixture, the worker can manually crank the turntable to rotate the bidirectional screw rod inside the clamping plate. As the bidirectional screw rod rotates inside the clamping plate, the fixing blocks move closer together. By fixing the top surface of the fixing blocks to the bottom surface of the clamping clamps, the air pressure reducing valve body is clamped and fixed by the close proximity of the clamping clamps, making it convenient for workers to clamp air pressure reducing valve bodies of different sizes.

[0004] While the aforementioned machining fixtures for air pressure reducing valves can improve the ease of assembly to some extent, it has been found in actual use that the special structures of the inlet and outlet connectors require manual pre-tightening before assembly with the valve seat. This not only results in low assembly efficiency but also low automation, requiring workers to operate one by one, which is time-consuming and labor-intensive. Summary of the Invention

[0005] Therefore, it is necessary to provide a quick tightening device for electromechanical installation to address the problems of low efficiency, time and labor costs in the current gas pressure reducing valve assembly process.

[0006] The above objectives are achieved through the following technical solutions:

[0007] A quick-tightening device for electromechanical installation, the device being used to thread a vent connector onto a valve seat, and comprising:

[0008] An operating table is provided with a first conveyor belt and a second conveyor belt arranged parallel to each other and spaced apart. The first conveyor belt and the second conveyor belt both form a closed conveying loop on the operating table. The first conveyor belt is used to convey the valve seat, and the second conveyor belt is used to convey the vent connector. An assembly station is provided on the conveying loop of the first conveyor belt, and a clamping station is provided on the conveying loop of the second conveyor belt.

[0009] A screw-clamping mechanism is disposed on the operating table and located between the first conveyor belt and the second conveyor belt. The screw-clamping mechanism includes a slide and a screw-clamping assembly disposed on the slide. The slide is movable along the width direction of the first conveyor belt, and the screw-clamping assembly is capable of revolving around a vertical line. It has a first position and a second position before and after rotation. When it is in the first position, the screw-clamping assembly faces the clamping station and is used to receive and clamp the vent connector. When it is in the second position, the screw-clamping assembly faces the assembly station and is used to screw the vent connector onto the valve seat.

[0010] A clamping and transferring mechanism is provided on the operating table and configured to first clamp the vent connector located at the clamping station, and then transfer the clamped vent connector to the screw clamping assembly.

[0011] A positioning mechanism is provided on the operating table and configured to fix the valve seat at the assembly station.

[0012] Furthermore, the vent connector is configured as a tubular structure with a screwing part in its middle, the screwing part being configured as an annular wave-shaped structure; the screwing clamping assembly includes a clamping cylinder and multiple clamping parts, the clamping cylinder being horizontally positioned and capable of rotation; the multiple clamping parts are circumferentially inserted into the clamping cylinder and can simultaneously slide along the radial direction of the clamping cylinder to push against the trough of the screwing part.

[0013] Furthermore, the clamping and transferring mechanism includes a cylinder seat and a rotating assembly. The cylinder seat is movable along the bandwidth of the first conveyor belt and can receive fluid from the outside. A hollow insert rod is provided on the cylinder seat, the insert rod is connected to the cylinder seat and extends along a bandwidth parallel to the first conveyor belt. A flexible bladder is sleeved on the insert rod. The flexible bladder is used to expand when fluid is filled into the cylinder seat and push against the inner peripheral wall of the vent connector. The rotating assembly is configured to drive the cylinder seat to rotate around the axis of the insert rod so that the trough of the screwing part corresponds to the clamping part.

[0014] Furthermore, the rotating assembly includes a first drive motor, the motor shaft of which is connected to the cylinder base, and the axis of the first drive motor coincides with the axis of the insertion rod.

[0015] Furthermore, the rotating assembly also includes a first elastic element, which is connected between the motor shaft of the first drive motor and the cylinder seat; the clamping part includes a clamping rod, a chuck and a second elastic element, the chuck is sleeved on the end of the clamping rod and located inside the clamping cylinder, and is connected to the clamping rod through the second elastic element, and the chuck tends to move away from the clamping rod under the action of the second elastic element.

[0016] Furthermore, the first elastic element includes a torsion spring.

[0017] Furthermore, the second conveyor belt is provided with a plurality of mounting parts, which are arranged at intervals along the conveying direction of the second conveyor belt. The mounting parts are configured as U-shaped structures with their openings facing upwards in the vertical direction, and are used to support the ventilation connector.

[0018] Furthermore, there are two screw-clamping assemblies, which are symmetrically arranged on the slide.

[0019] Furthermore, the twisting clamping mechanism also includes a drive assembly configured to provide a driving force for moving the slide along the bandwidth direction of the first conveyor belt.

[0020] Furthermore, the positioning mechanism includes a first drive cylinder, the output shaft of which is arranged vertically downward and presses against the top of the valve seat during use.

[0021] The beneficial effects of this invention are:

[0022] The quick tightening device for electromechanical installation provided by this invention first transports a valve seat via a first conveyor belt and a vent connector via a second conveyor belt. When the valve seat moves to the assembly station, it is positioned by a positioning mechanism. When the vent connector moves to the clamping station, the clamping and transferring mechanism first clamps the vent connector at the clamping station, then transfers the clamped vent connector to the screw clamping assembly. The screw clamping assembly then receives and clamps the vent connector, and rotates 180 degrees around a vertical line from the first position to the second position. Finally, the screw clamping assembly screws the vent connector onto the valve seat. This achieves automated assembly of the vent connector and valve seat, reduces manual intervention, lowers labor costs, and improves assembly efficiency and effectiveness.

[0023] Furthermore, by setting two screw clamping components symmetrically on the slide, during use, when one screw clamping component receives and clamps the vent connector, the other screw clamping component can screw the vent connector onto the valve seat. Then, the two screw clamping components can rotate 180 degrees around the vertical line. When one screw clamping component screws the vent connector onto the valve seat, the other screw clamping component can simultaneously receive and clamp the vent connector, thereby improving assembly efficiency.

[0044] like Figures 1 to 10 As shown, an embodiment of the present invention provides a quick tightening device for electromechanical installation, which is used to thread a vent connector 5 onto a valve seat 6. The vent connector 5 includes two types: an inlet connector and an outlet connector. The quick tightening device for electromechanical installation is configured to include an operating table 1, a screwing and clamping mechanism 2, a clamping and transferring mechanism 3, and a positioning mechanism. A first conveyor belt 11 and a second conveyor belt 12 are arranged parallel to each other and spaced apart on the operating table 1. The first conveyor belt 11 and the second conveyor belt 12 both form closed conveying loops on the operating table 1. The first conveyor belt 11 is used to convey the valve seat 6, and the second conveyor belt 12 is used to convey the vent connector 5. An assembly station 111 is provided on the conveying loop of the first conveyor belt 11, and a clamping station 121 is provided on the conveying loop of the second conveyor belt 12.

[0045] The screwing and clamping mechanism 2 is mounted on the operating table 1 and located between the first conveyor belt 11 and the second conveyor belt 12. The screwing and clamping mechanism 2 includes a slide 21 and a screwing and clamping assembly 25 mounted on the slide 21. The slide 21 can move along the width direction of the first conveyor belt 11. The screwing and clamping assembly 25 can revolve around a vertical line and has corresponding first and second positions before and after rotation. When in the first position, the screwing and clamping assembly 25 faces the clamping station 121 and is used to receive and clamp the vent connector 5. When in the second position, the screwing and clamping assembly 25 faces the assembly station 111 and is used to screw the vent connector 5 onto the valve seat 6.

[0046] The clamping and transferring mechanism 3 is set on the operating table 1 and is configured to first clamp the vent connector 5 located at the clamping station 121, and then transfer the clamped vent connector 5 to the screw clamping assembly 25.

[0047] The positioning mechanism is set on the operating table 1 and configured to fix the valve seat 6 at the assembly station 111.

[0048] Specifically, in this embodiment, such as Figure 1As shown, the operating platform 1 is configured as a T-shaped structure, with a horizontal section and a vertical section connected vertically. The first conveyor belt 11 is installed parallel to the vertical section of the operating platform 1, and the second conveyor belt 12 is installed vertically to the horizontal section of the operating platform 1. The assembly station 111 is located at the top middle position of the first conveyor belt 11, and the clamping station 121 is located at the top middle position of the second conveyor belt 12. The way in which the first conveyor belt 11 and the second conveyor belt 12 form a closed conveying loop is existing technology and will not be described in detail.

[0049] like Figure 5 As shown, the slide 21 is configured as a cross-shaped block structure, such as... Figure 1 As shown, a slide groove 102 is provided at the top of the horizontal section of the operating table 1. The slide groove 102 is parallel to the horizontal section of the operating table 1. During installation, the bottom of the slide block 21 is slidably inserted into the slide groove 102. To facilitate the rotation of the screw clamping assembly 25 around a vertical line, a second drive motor (not shown) is provided at the top of the slide block 21. The motor shaft of the second drive motor is arranged vertically upwards, as shown in the figure. Figure 5 As shown, a rotating seat 22 is provided on the motor shaft of the second drive motor. The screwing clamping assembly 25 is installed on the side wall of the rotating seat 22. At this time, the vertical line around which the screwing clamping assembly 25 revolves during its revolution coincides with the axis of the motor shaft of the second drive motor. In order to facilitate screwing the vent connector 5 onto the valve seat 6, a third drive motor 23 is provided on the side wall of the rotating seat 22. The motor shaft of the third drive motor 23 is horizontally arranged, and the screwing clamping assembly 25 is installed on the motor shaft of the third drive motor 23.

[0050] Initially, the screw clamping assembly 25 is in the first position and faces the clamping station 121.

[0051] During assembly, the valve seat 6 is first conveyed by the first conveyor belt 11, and the vent connector 5 is simultaneously conveyed by the second conveyor belt 12. When the valve seat 6 moves to the assembly station 111, the conveying of the first conveyor belt 11 is stopped, and the valve seat 6 is fixed at the assembly station 111 by the positioning mechanism. When the vent connector 5 moves to the clamping station 121, the conveying of the second conveyor belt 12 is stopped, and the vent connector 5 located at the clamping station 121 is first clamped by the clamping and transferring mechanism 3. Then, the clamped vent connector 5 is transferred to the screw clamping assembly 25, which receives and clamps the vent connector 5. Finally, the second drive motor is activated. The machine, the second drive motor drives the screw clamping assembly 25 to revolve 180 degrees around the axis of the second drive motor through the rotating seat 22, so that the screw clamping assembly 25 rotates from the first position to the second position, so that the screw clamping assembly 25 faces the assembly station 111. Then the third drive motor 23 is started, and at the same time the slide 21 is moved closer to the first conveyor belt 11. The third drive motor 23 drives the air connector 5 to rotate through the screw clamping assembly 25, so as to screw the air connector 5 onto the valve seat 6. In this way, the assembly of the air connector 5 and the valve seat 6 can be automated, and manual intervention can be reduced. While reducing labor costs, assembly efficiency and assembly benefits can be improved.

[0052] By repeating the above assembly process, the air connector 5 and valve seat 6 can be assembled continuously.

[0053] In some embodiments, the vent connector 5 is configured as a tubular structure, and a screwing part 51 is provided in its middle, the screwing part 51 being configured as an annular wave-shaped structure; the screwing clamping assembly 25 is configured to include a clamping cylinder 251 and a plurality of clamping parts 252, the clamping cylinder 251 being horizontally arranged and capable of rotation; the plurality of clamping parts 252 are inserted circumferentially into the clamping cylinder 251 and are capable of sliding synchronously along the radial direction of the clamping cylinder 251, so as to push against the trough of the screwing part 51.

[0054] Specifically, in this embodiment, such as Figure 10 As shown, the screwing part 51 can be configured to have four peaks and four troughs, with the four peaks evenly arranged circumferentially and a trough between every two adjacent peaks. The diameters of the tubular portions on both sides of the screwing part 51 are different, and the diameter of the tubular portion on the left is larger than that of the tubular portion on the right.

[0055] like Figure 2As shown, the clamping cylinder 251 is configured as a cylindrical structure with an open left end. During installation, the axis of the clamping cylinder 251 coincides with the axis of the third drive motor 23. Four clamping parts 252 can be provided, evenly arranged circumferentially. To facilitate the provision of driving force for the clamping parts 252 to slide radially along the clamping cylinder 251, the screw-clamping assembly 25 further includes four second drive cylinders 253. These four second drive cylinders 253 are evenly arranged circumferentially along the clamping cylinder 251, and their output shafts all point towards the axis of the clamping cylinder 251, with the axis perpendicular to the axis of the clamping cylinder 251. The clamping parts 252 are located at the ends of the output shafts of the second drive cylinders 253 during installation. To facilitate the installation of the four second drive cylinders 253, the screw-clamping assembly 25 also includes a rotating frame 2. 4. The rotating frame 24 is configured with a connecting plate portion and four support plate portions. The connecting plate portion is square in shape and is vertically and fixedly connected to the end of the motor shaft of the third drive motor 23 during installation. The center of the connecting plate portion coincides with the axis of the motor shaft of the third drive motor 23. The support plate portions are L-shaped and have a vertically connected horizontal section and a vertical section. During installation, the support plate portions are evenly distributed circumferentially on the four side walls of the connecting plate portion. The end of the suspended end of the vertical section of the support plate portion is vertically set on the side wall of the connecting plate portion. The horizontal section of the support plate portion is parallel to the axis of the clamp 251 and is located outside the clamp 251. The second drive cylinder 253 is set at the end of the suspended end of the horizontal section of the support plate portion during installation.

[0056] Understandably, the second drive cylinder 253 can be configured as any one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0057] During use, when the clamping and transferring mechanism 3 moves the clamped vent connector 5 to the screwing clamping assembly 25, four second drive cylinders 253 are activated simultaneously. The output shafts of the second drive cylinders 253 extend and simultaneously drive the clamping part 252 to move inward along the radial direction of the clamping cylinder 251 until it is pushed against the trough of the screwing part 51, so as to complete the clamping of the vent connector 5.

[0058] When the screw clamping assembly 25 is oriented toward the assembly station 111, the third drive motor 23 is started. The third drive motor 23 drives the clamping cylinder 251 to rotate synchronously through the rotating frame 24, and at the same time drives the slide block 21 to move toward the first conveyor belt 11. This causes the clamping cylinder 251 to move toward the first conveyor belt 11 synchronously. Since the clamping part 252 is always clamped on the vent connector 5, the vent connector 5 moves toward the first conveyor belt 11 synchronously along with the clamping cylinder 251 while rotating, and is threaded onto the valve seat 6.

[0059] In a further embodiment, the clamping and transferring mechanism 3 is configured to include a cylinder seat 31 and a rotating assembly. The cylinder seat 31 is movable along the bandwidth of the first conveyor belt 11 and can receive fluid from the outside. A hollow insert rod 32 is provided on the cylinder seat 31. The insert rod 32 communicates with the cylinder seat 31 and extends along the bandwidth of the first conveyor belt 11. A flexible bladder 33 is sleeved on the insert rod 32. The flexible bladder 33 is used to expand and push against the inner peripheral wall of the vent connector 5 when fluid is filled into the cylinder seat 31. The rotating assembly is configured to drive the cylinder seat 31 to rotate around the axis of the insert rod 32 so that the trough of the screwing part 51 corresponds to the clamping part 252.

[0060] Specifically, in this embodiment, such as Figure 4 As shown, the cylinder seat 31 is a cubic structure with a hollow interior, and the insertion rod 32 is vertically mounted on the front side wall of the cylinder seat 31. To facilitate the reception of fluid from the outside, a connecting pipe 311 is vertically and openly installed at the top of the cylinder seat 31. To allow fluid entering through the connecting pipe 311 to move into the flexible bladder 33, as shown... Figure 9 As shown, three sets of connecting ports 321 are provided on the circumferential sidewall of the end of the insert rod 32 away from the cylinder seat 31. The three sets of connecting ports 321 are evenly arranged in the circumferential direction, and each set includes three connecting ports 321. The three connecting ports 321 in the same set are arranged at equal intervals along the extension direction of the insert rod 32. The flexible bladder 33 is configured to have three sub-bladders. The three sub-bladders and the three sets of connecting ports 321 are respectively set accordingly. The sub-bladders are set as strip structures, and the cross-sectional shape is set as fan-shaped rings. When the sub-bladders are installed, they are set parallel to the insert rod 32. Three insert tubes 331 are vertically and connected on the arc wall of the sub-bladder facing the insert rod 32. The three insert tubes 331 are arranged at equal intervals along the extension direction of the sub-bladders. When the three insert tubes 331 on the same sub-bladder are installed, they are fixedly inserted into the three connecting ports 321 in the same set.

[0061] To provide the driving force for the cylinder seat 31 to move along the bandwidth direction of the first conveyor belt 11, the clamping and transferring mechanism 3 is configured to also include a third drive cylinder 35, such as... Figure 1 As shown, the third drive cylinder 35 is installed on the top left side of the horizontal section of the operating table 1, and the output shaft of the third drive cylinder 35 is parallel to the horizontal section of the operating table 1 and connected to the left side wall of the cylinder seat 31.

[0062] Understandably, the third drive cylinder 35 can be configured as any one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0063] During use, taking air as an example, when the vent connector 5 moves to the clamping station 121, the second conveyor belt 12 is stopped first, and then the third drive cylinder 35 is started. The output shaft of the third drive cylinder 35 extends, and simultaneously drives the cylinder seat 31 to move along the width direction of the first conveyor belt 11 until the flexible bladder 33 is inserted into the vent connector 5. Then the third drive cylinder 35 is closed, and air is filled into the cylinder seat 31 through the connecting pipe 311. The air enters the flexible bladder 33 through the insertion pipe 331, the connecting port 321, and the insertion pipe 331 in sequence, causing the flexible bladder 33 to expand and push against the inner peripheral wall of the vent connector 5 to complete the clamping of the vent connector 5.

[0064] Then the third drive cylinder 35 is started, and the output shaft of the third drive cylinder 35 continues to extend, synchronously driving the cylinder seat 31 to continue moving along the width direction of the first conveyor belt 11 until the air connector 5 is inserted into the clamp 251. Then the third drive cylinder 35 is closed, and the air connector 5 is rotated by the rotating component, so that the trough of the screwing part 51 and the clamping part 252 are set accordingly.

[0065] It is understandable that an air pump can be installed, with the exhaust end of the air pump connected to the connecting pipe 311, to facilitate the filling of air into the cylinder seat 31.

[0066] In a further embodiment, the rotating assembly is configured to include a first drive motor 341, the motor shaft of the first drive motor 341 being connected to the cylinder seat 31, and the axis of the first drive motor 341 coinciding with the axis of the insert rod 32.

[0067] Specifically, in this embodiment, such as Figure 4 As shown, the motor shaft of the first drive motor 341 is vertically mounted on the rear side wall of the cylinder seat 31 during installation.

[0068] More specifically, a mounting plate 351 is fixedly installed on the output shaft of the third drive cylinder 35. The mounting plate 351 has a horizontal section and a vertical section that are vertically connected. The first drive motor 341 is vertically installed on the vertical section of the mounting plate 351 during installation.

[0069] When in use, the first drive motor 341 is started. The first drive motor 341 drives the air connector 5 to rotate synchronously through the cylinder seat 31, the insert rod 32, and the flexible bladder 33, so that the trough of the screwing part 51 corresponds to the clamping part 252.

[0070] It is understandable that by setting up a camera to obtain the relative positional relationship between the vent connector 5 and the clamping part 252 in real time, the angle at which the first drive motor 341 drives the vent connector 5 to rotate can be adjusted, so that the trough of the screwing part 51 can correspond to the clamping part 252.

[0071] In a further embodiment, to reduce manufacturing costs and the difficulty of adjustment, the rotating assembly is configured to further include a first elastic element, which is connected between the motor shaft of the first drive motor 341 and the cylinder seat 31; the clamping part 252 is configured to include a clamping rod 2521, a chuck 2522 and a second elastic element, the chuck 2522 is sleeved on the end of the clamping rod 2521 and located inside the clamping cylinder 251, and is connected to the clamping rod 2521 through the second elastic element, and the chuck 2522 tends to move away from the clamping rod 2521 under the action of the second elastic element.

[0072] Specifically, in this embodiment, the first elastic element can be a torsion spring, connected between the motor shaft of the first drive motor 341 and the cylinder base 31; for example... Figure 8 As shown, the clamping rod 2521 is configured as a cross-shaped cylindrical structure, and the chuck 2522 is configured as a U-shaped block structure, which is sleeved on the end of the clamping rod 2521 near the axis of the clamping cylinder 251 during installation. The second elastic element can be configured as a compression spring 2523, which is sleeved on the clamping rod 2521 during installation and connected between the clamping rod 2521 and the chuck 2522. The output shaft of the second drive cylinder 253 is coaxial and fixedly connected to the end of the clamping rod 2521 during installation. To facilitate the placement of the chuck 2522 and the compression spring 2523, as shown... Figure 2 As shown, four mounting blocks 2511 are provided on the outer peripheral wall of the clamp 251. The four mounting blocks 2511 are evenly arranged in the circumferential direction and are set as hollow structures. They are correspondingly set to the second drive cylinder 253. The chuck 2522 and the compression spring 2523 are inserted into the mounting blocks 2511 during installation.

[0073] During use, when the cylinder seat 31 continues to move along the width direction of the first conveyor belt 11 until the vent connector 5 is inserted into the clamp 251, the clamp 2522 may be located at the crest of the twisting part 51 or at the trough of the twisting part 51. At this time, the first drive motor 341 is started. The first drive motor 341 drives the vent connector 5 to rotate back and forth slightly through the torsion spring, cylinder seat 31, insert rod 32, and flexible bladder 33. Due to the setting of the torsion spring, the cylinder seat 31, insert rod 32, flexible bladder 33 and vent connector 5 rotate as a whole with a lag.

[0074] When the chuck 2522 is located at the trough of the screwing part 51, the chuck 2522 is pushed against the trough under the action of the compression spring 2523. During the small-amplitude reciprocating rotation of the motor shaft of the first drive motor 341, since all four troughs of the screwing part 51 are pushed against by the chuck 2522, the vent connector 5 is clamped, which in turn makes the first drive motor 341 only able to drive the torsion spring to rotate.

[0075] When the chuck 2522 is located at the crest of the twisting part 51, the compression spring 2523 is further compressed. During the small-amplitude reciprocating rotation of the motor shaft of the first drive motor 341, the first drive motor 341 drives the vent connector 5 to rotate small-amplitude through the torsion spring, cylinder seat 31, insert rod 32, and flexible bladder 33. When the vent connector 5 rotates to correspond with the trough of the chuck 2522 and the twisting part 51, the chuck 2522 can quickly extend and push against the trough under the action of the compression spring 2523. Since all four troughs of the twisting part 51 are abutted by the chuck 2522, the vent connector 5 is clamped, so that the first drive motor 341 can only drive the torsion spring to rotate.

[0076] Then, the four second drive cylinders 253 are started simultaneously. The output shafts of the second drive cylinders 253 extend and simultaneously drive the clamp 2522 to move inward along the radial direction of the clamping cylinder 251 through the clamping rod 2521, so that the compression spring 2523 is further compressed, thereby clamping the vent connector 5.

[0077] In other embodiments, since the vent connector 5 is configured as a tubular structure, the vent connector 5 may roll due to inertia during the start-up or stop of the second conveyor belt 12, thereby changing its position on the second conveyor belt 12 and affecting the vent connector 5 from staying at the clamping station 121. To solve this problem, a plurality of mounting parts 122 are provided on the second conveyor belt 12. The plurality of mounting parts 122 are arranged at intervals along the conveying direction of the second conveyor belt 12. The mounting parts 122 are configured as U-shaped structures with the openings facing upwards in the vertical direction and are used to support the vent connector 5.

[0078] Specifically, in this embodiment, such as Figure 2 As shown, the mounting part 122 is configured as a strip structure and extends along the width direction of the second conveyor belt 12. The vent connector 5 is inserted parallel to the mounting part 122 during installation.

[0079] During the start-up or stop of the second conveyor belt 12, even if the vent joint 5 may roll due to inertia, the vent joint 5 can return to the middle position of the mounting part 122 under the action of gravity after moving due to the arc surface restriction of the mounting part 122. This keeps the relative position between the vent joint 5 and the second conveyor belt 12 unchanged and avoids affecting the vent joint 5 staying at the clamping position 121.

[0080] Similarly, to prevent the valve seat 6 from rolling due to inertia during the start-up or stop of the first conveyor belt 11, thereby changing its position on the first conveyor belt 11 and affecting the valve seat 6 from staying at the assembly station 111, multiple fixing parts are provided on the first conveyor belt 11. The multiple fixing parts are arranged at equal intervals along the conveying direction of the first conveyor belt 11 and are used to support the valve seat 6.

[0081] In other embodiments, to improve assembly efficiency, two screw clamping assemblies 25 are provided, and they are symmetrically arranged on the slide 21.

[0082] Specifically, in this embodiment, such as Figure 5 As shown, there are two third drive motors 23, which are symmetrically arranged on the left and right side walls of the rotating seat 22. There are two rotating frames 24, which are arranged in a one-to-one correspondence with the third drive motors 23. The two screw clamping assemblies 25 and the two rotating frames 24 are arranged in a one-to-one correspondence.

[0083] In use, when the left-side screw clamping assembly 25 receives and clamps the vent connector 5, the right-side screw clamping assembly 25 can screw the vent connector 5 onto the valve seat 6, thereby avoiding the empty stroke of the screw clamping assembly 25 and improving assembly efficiency.

[0084] In other embodiments, the screw clamping mechanism 2 is configured to further include a drive assembly 26, which is configured to provide a driving force for moving the slide 21 along the bandwidth direction of the first conveyor belt 11.

[0085] Specifically, in this embodiment, the drive assembly 26 can be configured to include a fourth drive motor 261 and a lead screw 262, such as... Figure 1 As shown, the fourth drive motor 261 is installed on the left side wall of the horizontal section of the operating table 1. The lead screw 262 is inserted into the slide groove 102 and is set parallel to the horizontal section of the operating table 1. The motor shaft of the fourth drive motor 261 is coaxial and fixedly connected to the left end of the lead screw 262. The slide block 21 is screwed onto the lead screw 262 during installation.

[0086] When in use, the fourth drive motor 261 is started, and the fourth drive motor 261 drives the slide 21 to move along the width direction of the first conveyor belt 11 through the lead screw 262.

[0087] It is understood that the drive assembly 26 may be configured to include a fourth drive cylinder, which is installed on the left side wall of the horizontal section of the operating table 1, and the output shaft of the fourth drive cylinder is parallel to the horizontal section of the operating table 1, inserted into the slide groove 102, and fixedly connected to the left side wall of the slide block 21.

[0088] When in use, the fourth drive cylinder is activated, and the output shaft of the fourth drive cylinder extends or retracts, synchronously driving the slide 21 to move along the width direction of the first conveyor belt 11.

[0089] Understandably, the fourth drive cylinder can be configured as any of the following: a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0090] In other embodiments, the positioning mechanism is configured to include a first drive cylinder 41, the output shaft of which is arranged vertically downward and pressed against the top of the valve seat 6 during use.

[0091] Specifically, in this embodiment, to facilitate the installation of the first drive cylinder 41, such as Figure 2 As shown, a support 101 is provided on the vertical section of the operating table 1. The support 101 is an L-shaped plate structure and is installed in accordance with the assembly station 111. The support 101 has a horizontal section and a vertical section that are vertically connected. The end of the vertical section of the support 101 is vertically set on the vertical section of the operating table 1. The horizontal section of the support 101 extends along the width direction of the first conveyor belt 11 and is located above the first conveyor belt 11. The first drive cylinder 41 is set at the end of the horizontal section of the support 101 away from the end of the vertical section of the support 101 during installation.

[0092] When the valve seat 6 moves to the assembly station 111, the conveying of the first conveyor belt 11 is stopped, and the first drive cylinder 41 is started. The output shaft of the first drive cylinder 41 extends and presses on the top of the valve seat 6 to fix the valve seat 6 at the assembly station 111.

[0093] It is understandable that the first drive cylinder 41 can be configured as any one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0094] Based on the above embodiments, the usage principle and working process of the embodiments of the present invention are as follows:

[0095] Initially, one of the screw clamping components 25 faces the clamping station 121, and the other screw clamping component 25 faces the assembly station 111.

[0096] During assembly, valve seats 6 are first placed one-to-one in the fixing part, and vent connectors 5 are placed one-to-one in the mounting part 122. Then, valve seats 6 are transported by the first conveyor belt 11, and vent connectors 5 are transported by the second conveyor belt 12. When valve seats 6 move to assembly station 111, the first conveyor belt 11 is stopped, and the first drive cylinder 41 is started. The output shaft of the first drive cylinder 41 extends and presses against the top of valve seats 6. When vent connectors 5 move to clamping station 121, the second drive cylinder 41 is stopped. The conveyor belt 12 conveys the material, and then the third drive cylinder 35 is started. The output shaft of the third drive cylinder 35 extends, and simultaneously drives the cylinder seat 31 to move along the width direction of the first conveyor belt 11 until the flexible bladder 33 is inserted into the vent joint 5. Then the third drive cylinder 35 is closed, and the air pump is started. The air pump fills the cylinder seat 31 with air through the connecting pipe 311. The air enters the flexible bladder 33 through the insertion pipe 331, the connecting port 321, and the insertion pipe 331 in sequence, causing the flexible bladder 33 to expand and push against the inner peripheral wall of the vent joint 5.

[0097] Then the third drive cylinder 35 is started, and the output shaft of the third drive cylinder 35 continues to extend, synchronously driving the cylinder seat 31 to continue moving along the width direction of the first conveyor belt 11 until the air connector 5 is inserted into the clamp 251 of the screw clamping assembly 25 located on the left. Then the third drive cylinder 35 is closed, and the first drive motor 341 is started. The first drive motor 341 drives the air connector 5 to rotate back and forth slightly through the torsion spring, cylinder seat 31, insert rod 32, and flexible bladder 33. Due to the setting of the torsion spring, the cylinder seat 31, insert rod 32, flexible bladder 33 and air connector 5 rotate as a whole with a lag.

[0098] When the chuck 2522 is located at the trough of the screwing part 51, the chuck 2522 is pushed against the trough under the action of the compression spring 2523. During the small-amplitude reciprocating rotation of the motor shaft of the first drive motor 341, since all four troughs of the screwing part 51 are pushed against by the chuck 2522, the vent connector 5 is clamped, which in turn makes the first drive motor 341 only able to drive the torsion spring to rotate.

[0099] When the chuck 2522 is located at the crest of the twisting part 51, the compression spring 2523 is further compressed. During the small-amplitude reciprocating rotation of the motor shaft of the first drive motor 341, the first drive motor 341 drives the vent connector 5 to rotate small-amplitude through the torsion spring, cylinder seat 31, insert rod 32, and flexible bladder 33. When the vent connector 5 rotates to correspond with the trough of the chuck 2522 and the twisting part 51, the chuck 2522 can quickly extend and push against the trough under the action of the compression spring 2523. Since all four troughs of the twisting part 51 are abutted by the chuck 2522, the vent connector 5 is clamped, so that the first drive motor 341 can only drive the torsion spring to rotate.

[0100] Then, the first drive motor 341 is turned off, and the four second drive cylinders 253 are started simultaneously. The output shaft of the second drive cylinder 253 extends out and drives the clamp 2522 to move inward along the radial direction of the clamping cylinder 251 through the clamping rod 2521, so that the compression spring 2523 is further compressed, thereby clamping the vent connector 5.

[0101] At the same time, it resets the clamping and transferring mechanism 3.

[0102] Then the second drive motor is started. The second drive motor drives the left-side screw clamping assembly 25 to revolve 180 degrees around the axis of the second drive motor through the rotating seat 22, so as to rotate from the first position to the second position, so that the screw clamping assembly 25 holding the air connector 5 faces the assembly station 111.

[0103] Then the fourth drive motor 261 is started. The fourth drive motor 261 drives the slide 21 to move along the width direction of the first conveyor belt 11 through the lead screw 262 to the vent connector 5 and initially insert it into the valve seat 6.

[0104] Then, the third drive motor 23 is started. The third drive motor 23 drives the clamp 251 to rotate synchronously through the rotating frame 24. At the same time, the fourth drive motor 261 is started. The fourth drive motor 261 drives the slide 21 to move along the width direction of the first conveyor belt 11 through the lead screw 262, so that the clamp 251 moves synchronously towards the first conveyor belt 11. Since the clamping part 252 is always clamped on the vent connector 5, the vent connector 5 moves synchronously with the clamp 251 while rotating and towards the first conveyor belt 11, and is threaded onto the valve seat 6.

[0105] After the vent connector 5 and valve seat 6 are assembled, the second drive cylinder 253 is started, the output shaft of the second drive cylinder 253 retracts, and the compression spring 2523 is released; then the fourth drive motor 261 is started, and the fourth drive motor 261 drives the slide block 21 to move along the width direction of the first conveyor belt 11 and away from the first conveyor belt 11 through the lead screw 262, so that the assembled vent connector 5 is disengaged from the clamp 251.

[0106] Simultaneously, the ventilation connector 5 is conveyed by the second conveyor belt 12. When the ventilation connector 5 moves to the clamping station 121, the clamping and transferring mechanism 3 first clamps the ventilation connector 5 located at the clamping station 121, and then transfers the clamped ventilation connector 5 to the left-side screw clamping assembly 25. Then, the left-side screw clamping assembly 25 receives and clamps the ventilation connector 5.

[0107] Then, by repeating the above assembly process, the air connector 5 and valve seat 6 can be assembled continuously.

[0108] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0109] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
