A movable faucet switch is connected to the outside of the faucet head, and this switch connects to the valve core switch. Operating the faucet switch allows for the opening and closing of the valve core switch. To perform an air test on the faucet assembly, the faucet switch is typically removed, exposing the valve core switch to the outside of the faucet head, and then the faucet is manually tested. Furthermore, current methods require manual connection of the water pipes to the faucet during assembly. This manual method of tightening pipes and testing is very time-consuming, resulting in low production efficiency and low production line output. Summary of the Invention

[0033] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0034] like Figures 1 to 9 As shown, this embodiment of the invention provides a dual-station automatic air-testing and tightening machine for connecting a pair of water pipes 23 to a faucet 20 to assemble a faucet assembly and for testing the faucet assembly with air. The faucet 20 has a valve core switch 22 exposed to the outside. The dual-station automatic air-testing and tightening machine includes: a frame 1 with a base 7 supporting the faucet 20; a fixing mechanism 4 located at the lower part of the frame 1 for applying pressure to the faucet 20 to fix it to the base 7; a clamping mechanism 2 located at the upper part of the frame 1 for clamping the pair of water pipes 23 and driving the pair of water pipes 23 to move between a tightening station and an air-testing station; and a tightening mechanism 3 located at the upper part of the frame 1, positioned at the tightening station, for engaging the pair of water pipes 23 when they are in the tightening station. The upper ends of the pair of water pipes 23 are driven to rotate relative to the faucet 20, so that the lower ends of the pair of water pipes 23 are fixedly connected to the faucet 20; the air intake mechanism 17 is disposed on the upper part of the frame 1, located at the air test station, and is connected to an external air filling device. When the pair of water pipes 23 are located at the air test station, the air intake mechanism 17 is sealed to the upper ends of the pair of water pipes 23 to connect the pair of water pipes 23 to the air filling device; the sealing mechanism 5 is disposed on the lower part of the frame 1 and seals the water outlet 21 of the faucet 20; the valve core adjustment mechanism 6 is disposed on the lower part of the frame 1 and is detachably connected to the valve core switch 22, driving the valve core switch 22 to switch between the open and closed states.

[0035] The faucet assembly includes a faucet 20 and a pair of water pipes 23. A valve core is installed inside the faucet 20. The pair of water pipes 23 are connected to the faucet 20, more specifically, to the valve core inside the faucet 20. A movable faucet switch is connected to the outer side of the head of the faucet 20. The faucet switch is connected to a valve core switch 22. By operating the faucet switch, the valve core switch 22 can be opened and closed. For air testing of the faucet assembly, the faucet switch is typically removed, exposing the valve core switch 22 to the outside of the head of the faucet 20.

[0036] When the dual-station automatic air-testing and tightening machine is working, the faucet assembly is placed upside down on the machine base 7. Pressure is applied to the faucet 20 via the fixing mechanism 4 to secure it to the machine base 7. At this time, a pair of water pipes 23 extend upwards. The clamping mechanism 2 clamps and fixes the pair of water pipes 23 to the tightening station. Then, the tightening mechanism 3 engages with the upper ends of the pair of water pipes 23, driving them to rotate relative to the faucet 20, thereby fixing the pair of water pipes 23 to the faucet 20, connecting them to the valve core inside the faucet 20. After the water pipes 23 are fixed, the clamping mechanism 2 moves the pair of water pipes 23 to the air-testing station. The air intake mechanism 17 is sealed and connected to the upper ends of the pair of water pipes 23, connecting them to the air-filling equipment. Before air testing, the sealing mechanism 5 seals the outlet 21 of the faucet 20, and the valve core adjustment mechanism 6 is connected to the valve core switch 22. Next, an air test is performed. The valve core is adjusted to the open or closed state using the valve core adjustment mechanism 6, and air is injected into a pair of water pipes 23 using an air inflation device to check for air leakage in the faucet assembly when the valve core is in the open or closed state.

[0037] In summary, the dual-station automatic air-testing and tightening machine provided by the present invention can automatically connect a pair of water pipes 23 to the faucet 20 and automatically test the faucet assembly with air, thereby improving the production efficiency of the faucet assembly and increasing the output of the production line.

[0038] In a preferred embodiment, in the dual-station automatic air-testing and pipe-twisting machine, the clamping mechanism 2 includes a clamp 8 and a first linear drive mechanism 19. The clamp 8 has a pair of front openings and vertically extending clamping portions. The clamp 8 is disposed on the upper part of the frame 1 in a manner that allows it to move between the pipe-twisting station and the air-testing station. The first linear drive mechanism 19 is disposed on the upper part of the frame 1 and is connected to the clamp 8 to drive the clamp 8 to move between the pipe-twisting station and the air-testing station.

[0039] When the clamping mechanism 2 is working, it clamps a pair of water pipes 23 into a pair of clamping parts of the clamp 8. The clamp 8 is mounted on a conveyor plate, which is slidably fixed to a clamp 8 base plate. The clamp 8 base plate is fixed to the frame 1, and the first linear drive mechanism 19 is fixed to the clamp 8 base plate. The first linear drive mechanism 19 drives the clamp 8 to move back and forth, thereby switching between the pipe tightening station and the air testing station. The first linear drive mechanism 19 is a first cylinder.

[0040] In a preferred embodiment, in the dual-station automatic air-testing and tightening machine, the tightening mechanism 3 includes a pair of clamping connectors 9 and a pair of rotary drive mechanisms 10. The pair of rotary drive mechanisms 10 are respectively connected to the pair of clamping connectors 9. When the pair of water pipes 23 are in the tightening station, the pair of clamping connectors 9 are respectively clamped to the upper end of the pair of water pipes 23. The pair of rotary drive mechanisms 10 respectively drive the pair of water pipes 23 to rotate relative to the faucet 20, so that the lower end of the pair of water pipes 23 is respectively fixedly connected to the faucet 20.

[0041] When the clamping mechanism 2 clamps and fixes the pair of water pipes 23, the pair of locking connectors 9 of the tightening mechanism 3 engage with the upper ends of the pair of water pipes 23, thereby fixing the tightening mechanism 3 and the pair of water pipes 23 together. Then, the rotary drive mechanism 10 drives the pair of water pipes 23 to rotate relative to the faucet 20, thereby tightening the pair of water pipes 23 onto the faucet 20, achieving a fixed connection between the pair of water pipes 23 and the faucet 20. The locking connector 9 can be a columnar protrusion that engages with the upper end of the water pipe 23, fitting tightly with it. The rotary drive mechanism 10 can be a motor.

[0042] In a preferred embodiment, the dual-station automatic air-testing and pipe-twisting machine further includes a second linear drive mechanism 11, which is disposed on the upper part of the frame 1. The pair of rotary drive mechanisms 10 are disposed on the upper part of the frame 1 in a liftable manner. The second linear drive mechanism 11 is connected to the pair of rotary drive mechanisms 10. When the pair of water pipes 23 are located at the pipe-twisting station, the second linear drive mechanism 11 drives the pair of rotary drive mechanisms 10 to descend, so as to clamp the pair of snap-fit ​​connectors 9 onto the upper end of the pair of water pipes 23 respectively, or drives the pair of rotary drive mechanisms 10 to rise, so as to disengage the pair of snap-fit ​​connectors 9 from the pair of water pipes 23.

[0043] When the clamping mechanism 2 clamps and fixes a pair of water pipes 23, the rotary drive mechanism 10 and the clamping connector 9 are initially positioned above the upper ends of the pair of water pipes 23. Then, the second linear drive mechanism 11 drives the rotary drive mechanism 10 to descend, clamping the pair of clamping connectors 9 onto the upper ends of the pair of water pipes 23, and then the pipe tightening operation is performed. After the pipe tightening operation is completed, the second linear drive mechanism 11 drives the rotary drive mechanism 10 to rise again, and the clamping connectors 9 disengage from the water pipes 23.

[0044] The second linear drive mechanism 11 can be a second cylinder. The second cylinder is fixed to a second cylinder mounting plate, and the cylinder mounting plate is then fixed to the frame 1.

[0045] In a preferred embodiment, in the dual-station automatic air-testing and tightening machine, the air intake mechanism 17 includes a pair of air intake clamps 24 and a pair of third linear drive mechanisms 18. The air intake clamps 24 have an internal air passage connecting the air intake end and the air outlet end of the air intake clamps 24. The air intake clamps 24 are connected to the inflation device through the air intake end, and the air outlet end is located at the lower end of the air intake clamps 24. The pair of third linear drive mechanisms 18 are respectively connected to the pair of air intake clamps 24. When the pair of water pipes 23 are located at the air-testing station, the pair of third linear drive mechanisms 18 respectively drive the pair of air intake clamps 24 to descend, so as to seal the air outlet end of the pair of air intake clamps 24 with the upper end of the pair of water pipes 23, thereby connecting the pair of water pipes 23 to the inflation device, or drive the pair of air intake clamps 24 to rise, so as to detach the pair of air intake clamps 24 from the pair of water pipes 23.

[0046] When the clamping mechanism 2 moves the pair of water pipes 23 to the air testing position, the third linear drive mechanism 18 drives the air intake clamp 24 to descend, sealing the air outlet end of the air intake clamp 24 with the upper end of the pair of water pipes 23, thereby connecting the pair of water pipes 23 to the air filling device. Afterwards, the air filling device supplies air to the water pipes 23 to perform an air test on the faucet assembly. After the air test is completed, the third linear drive mechanism 18 rises, causing the air intake clamp 24 to disengage from the water pipes 23.

[0047] The air intake mechanism 17 is located on the rear side of the pipe twisting mechanism 3. The third linear drive mechanism 18 can be a third cylinder. The third cylinder is fixed on a third cylinder mounting plate, which is fixed on the frame 1. The air intake clamp 24 is similar to a two-way valve structure and can be implemented using existing technologies.

[0048] The pipe tightening mechanism 3 and the clamping mechanism 2 are mounted on a fixed plate. A screw is mounted on the upper part of the frame 1. The fixed plate is fixed on the screw adjusting transmission plate. The screw adjusting transmission plate is sleeved on the screw. By adjusting the position of the screw adjusting transmission plate on the screw, the height of the pipe tightening mechanism 3 and the clamping mechanism 2 can be adjusted to accommodate water pipes 23 of different lengths.

[0049] In a preferred embodiment, in the dual-station automatic air testing and pipe tightening machine, the fixing mechanism 4 includes a fourth linear drive mechanism 12, which is disposed at the lower part of the frame 1. The fourth linear drive mechanism 12 applies pressure to the faucet 20 to fix the faucet 20 to the base 7.

[0050] The fourth linear drive mechanism 12 applies downward pressure, pressing against the faucet 20, thereby fixing the faucet 20 to the base 7. The fourth linear drive mechanism 12 can be a fourth cylinder, which is fixed to a fourth cylinder mounting plate. The fourth cylinder mounting plate is set on an adjusting mounting plate, which is fixed to the lower part of the frame 1 via the mounting plate. The height of the fourth cylinder is adjusted by adjusting the height of the fourth cylinder mounting plate on the adjusting mounting plate.

[0051] In a preferred embodiment, in the dual-station automatic air-testing and tightening machine, the sealing mechanism 5 includes a sealing head and a fifth linear drive mechanism 14. The fifth linear drive mechanism 14 is connected to the sealing head and drives the sealing head to descend, thereby sealing the water outlet 21 of the faucet 20.

[0052] A sealing head is connected to the lower end of the fifth linear drive mechanism 14. The fifth linear drive mechanism 14 drives the sealing head to descend, sealing the water outlet 21 of the faucet 20. After the air test is completed, the fifth linear drive mechanism 14 drives the sealing head to rise, and the sealing head leaves the water outlet 21.

[0053] The fifth linear drive mechanism 14 can be a fifth cylinder. The fifth cylinder is also fixed on the fourth cylinder mounting plate.

[0054] In a preferred embodiment, in the dual-station automatic air testing and tightening machine, the valve core adjustment mechanism 6 includes a valve core connecting member 25 and a sixth linear drive mechanism 15. The valve core connecting member 25 is detachably connected to the valve core switch 22, and the sixth linear drive mechanism 15 is connected to the valve core connecting member 25 to drive the valve core connecting member 25 to reciprocate so that the valve core switch 22 switches between an open state and a closed state.

[0055] The sixth linear drive mechanism 15 can drive the valve core connecting member 25 to swing left and right or up and down to simulate the control process of a faucet switch on the valve core switch 22, thereby realizing the opening and closing of the valve core switch 22. The swing mode of the valve core connecting member 25 is determined by the opening and closing mode of the valve core switch 22, and the present invention does not specifically limit this. The valve core connecting structure can be a fork-shaped member, with its fork-shaped front end engaging with the valve core switch 22, and its rear end connected to the sixth linear drive mechanism 15.

[0056] The sixth linear drive mechanism 15 can be a sixth cylinder, which is fixed on a sixth cylinder mounting plate, and the sixth cylinder mounting plate is fixed on the base plate of the frame 1.

[0057] In a preferred embodiment, in the dual-station automatic air-testing and tightening machine, the base 7 includes a slot 16 for accommodating the head of the faucet 20 and fixing the head of the faucet 20 inside it. The valve core switch 22 of the faucet 20 is located inside the slot 16. One side of the slot 16 has an operating port. The valve core connecting member 25 extends into the slot 16 through the operating port to connect to the valve core switch 22.

[0058] The base 7 has a slot 16 (or a faucet 20 clamp 8), in which the faucet 20 is placed upside down, with the valve core switch 22 at its head located below. The valve core connecting member 25 extends into the slot 16 and connects to the valve core switch 22. The operating port has sufficient space for the valve core connecting member 25 to swing left and right or up and down.

[0059] The following describes the working process of the dual-station automatic air testing and pipe tightening machine provided by this invention.

[0060] Tightening stage: Turn on the electrical switch; the fourth and fifth cylinders push outwards, the fifth cylinder fixes the faucet 20, and the sixth cylinder blocks the water outlet 21 of the faucet 20; the first cylinder pushes outwards, driving the clamp 8 and water pipe 23 to move below a pair of motors; a pair of second cylinders push outwards, and push the pair of motors with clamp 8 to make close contact with the upper end of the water pipe 23; the pair of motors rotate and automatically tighten the water pipe 23 to the faucet 20; the tightening is complete.

[0061] Air test phase: After the pipe tightening phase, the second cylinder extends inward to separate the water pipe 23 from the motor; the first cylinder extends inward to send the water pipe 23 to the bottom of the pair of third cylinders; the pair of third cylinders push outward to seal the air inlet clamp 24 with the water pipe 23; the sixth cylinder controls the valve core switch 22 of the faucet 20 and uses the air inlet clamp 24 to check whether the faucet assembly is leaking; all cylinders are restored and the air test is completed.

[0062] In summary, the dual-station automatic air-testing and tightening machine provided by the present invention can automatically connect a pair of water pipes 23 to the faucet and automatically test the faucet assembly with air, thereby improving the production efficiency of the faucet assembly and increasing the output of the production line.
