[0003] During the assembly process of the air valve pump, multiple solenoid valve cores need to be press-fitted in a standardized manner at multiple solenoid valve core installation positions. After the press-fitting is completed, a power-on test is required. If a conventional assembly line-style press-fitting test design is used, the efficiency is low and cannot meet the needs of automated assembly. Utility Model Content

[0004] In order to solve the technical problems of press-fitting and testing multiple electromagnetic valve cores of an air valve pump, the utility model provides an air valve pump electromagnetic valve core press-fitting mechanism. The following technical solutions are adopted:

[0006] There are two press-fitting assemblies, which surround the periphery of the rotating disk of the rotating mechanism. The press-fitting assemblies include a press-fitting base, an electric cross slide module, a press-fitting electric cylinder mechanism and a press-fitting rod. The bottom of the press-fitting base is installed on the frame, and a support plate is provided on the top. The support plate is provided with a press-fitting rod through hole. The track of the electric cross slide module is detachably installed on the support plate, and the shell of the press-fitting electric cylinder mechanism is detachably installed on the slider of the electric cross slide module. The press-fitting rod is detachably installed on the lifting part of the press-fitting electric cylinder mechanism. When the bottom of the press-fitting rod is aligned with the solenoid valve core to be pressed, the lifting part of the press-fitting electric cylinder mechanism outputs downward pressure to realize the pressing of the solenoid valve core to be pressed.

[0007] By adopting the above technical scheme and a rotating workstation design, the number of air valve pump body positioning tooling is six, including one loading station, two solenoid valve core placement stations, two pressing stations and one unloading station. The air valve pump to be pressed is placed on the loading station by a transfer robot, and the rotating disk of the rotating mechanism rotates clockwise, and the solenoid valve core transfer and placement robot component places the solenoid valve core to be pressed that has completed the power-on test on multiple solenoid valve core pressing positions of the air valve pump to be pressed. The air valve pump to be pressed may require solenoid valve cores of various specifications. Different solenoid valve core power-on test components and solenoid valve core transfer and placement robot components are matched according to different solenoid valve core specifications to complete the placement of multiple solenoid valve cores to be pressed into the pressing positions; the rotating disk of the rotating mechanism continues to rotate clockwise to the bottom of the pressing component. There are two pressing components, which press-fit different solenoid valve core positions of the air valve pump to be pressed, respectively, which can greatly improve the pressing efficiency. The entire pressing process is fully automated with high pressing efficiency.

Since one press-fitting component needs to press multiple solenoid valve cores to be pressed at different positions, an electric cross slide module is used to drive the pressing electric cylinder mechanism and the pressing rod to move in a high-precision plane. When reaching the specified position, the pressing electric cylinder mechanism drives the pressing rod to press down to complete the pressing. At the same time, the pressing monitoring component based on the pressure sensor and the displacement sensor can provide feedback on whether the pressing is qualified.

[0035] There are two press-fitting assemblies, which surround the periphery of the rotating disk of the rotating mechanism 11. The press-fitting assemblies include a press-fitting base 41, an electric cross slide module 42, a press-fitting electric cylinder mechanism 43 and a press-fitting rod 44. The bottom of the press-fitting base 41 is installed on the frame 100, and a support plate is provided on the top. The support plate is provided with a press-fitting rod through hole. The track of the electric cross slide module 42 is detachably installed on the support plate, and the shell of the press-fitting electric cylinder mechanism 43 is detachably installed on the slider of the electric cross slide module 42. The press-fitting rod 44 is detachably installed on the lifting part of the press-fitting electric cylinder mechanism 43. When the bottom of the press-fitting rod 44 is aligned with the solenoid valve core to be pressed, the lifting part of the press-fitting electric cylinder mechanism 43 outputs downward pressure to realize the pressing of the solenoid valve core to be pressed.

[0036] The rotary station design is adopted, and the number of air valve pump body positioning tooling 12 is six, including one loading station, two solenoid valve core placement stations, two pressing stations and one unloading station. The air valve pump to be pressed is placed on the loading station by a transfer robot, and the rotating disk of the rotating mechanism 11 rotates clockwise, and the solenoid valve core transfer and placement robot component places the solenoid valve core to be pressed that has completed the power-on test on multiple solenoid valve core pressing positions of the air valve pump to be pressed. The air valve pump to be pressed may require solenoid valve cores of various specifications. Different solenoid valve core transfer and placement robot components can be matched according to different solenoid valve core specifications to complete the placement of multiple solenoid valve cores to be pressed into the pressing positions; the rotating disk of the rotating mechanism 11 continues to rotate clockwise to the bottom of the pressing assembly. There are two pressing assemblies, which press-fit different solenoid valve core positions of the air valve pump to be pressed, respectively, which can greatly improve the pressing efficiency. The entire pressing process is fully automated and has high pressing efficiency.

[0037] Embodiment 2 also includes four groups of electromagnetic valve core transfer linear modules 22 and power-on test components 23. The downward pressure power-on test device 232 includes a gantry bracket 2321, four lifting drive mechanisms 2322, a clamping mechanism 2323, a power-on coil 2324, a test air circuit and a flow detection switch. Four detection positions are set on the crossbeam of the gantry bracket 2321. The four lifting drive mechanisms 2322 are respectively installed at the four detection positions. The clamping mechanisms 2323 are respectively installed at the lifting parts of the four lifting drive mechanisms 2322. The power-on coil 2324 is located at the clamping part of the clamping mechanism 2323 and moves up and down with the clamping part. When the power-on coil 2324 is pressed down to contact the electromagnetic valve core to be pressed, the electromagnetic valve core to be pressed is energized, the test air circuit is connected to the air circuit of the electromagnetic valve core to be pressed, and the flow detection switch realizes the power-on test of the electromagnetic valve core to be pressed by detecting the flow of the test air circuit.

[0038] Four sets of solenoid valve core transfer linear modules 22 are arranged side by side, all of which are electric linear slide modules, which can accurately control the linear movement position of the slider. The four lifting drive mechanisms 2322 can be electric cylinder drives, which can realize the alignment of the energized coil 2324 with the on-state potential of the solenoid valve core to be pressed, and realize power-on test. After power-on, compressed gas is delivered to the air circuit integrated on the solenoid valve core power-on test bench 231 through the test air circuit. The flow detection switch can detect the gas flow. If it is determined that the solenoid valve pump to be pressed can normally output the set gas volume, it is determined that the solenoid valve core power-on test is qualified.

[0039] In Example 3, the solenoid valve core power-on test assembly further includes a defective product conveying line 24, the feed end of which is located outside the feed end of the solenoid valve core transfer linear module 22, and is used to convey the solenoid valve cores that fail the power-on test outward.

[0045] The pressing of the press-fitting component is achieved by the press-fitting electric cylinder mechanism 43 driving the press-fitting rod 44 to press down. Since one press-fitting component needs to press-fit multiple solenoid valve cores to be pressed at different positions, an electric cross slide module 42 is used to drive the press-fitting electric cylinder mechanism 43 and the press-fitting rod 44 to move in a high-precision plane. When reaching the specified position, the press-fitting electric cylinder mechanism 43 drives the press-fitting rod 44 to press down to complete the press-fitting.

When the lifting mechanism 6 is lifted up, the clamping position of the air valve pump body positioning tool 12 is released, and when the lifting mechanism 6 is lowered, the clamping position of the air valve pump body positioning tool 12 is clamped.

[0050] The air valve pump body positioning tool 12 can adopt a positioning tool with a work position clamping function. The clamping position adopts an air valve pump clamping surface profiling design. After the jacking mechanism 6 is pushed upward, the clamping position of the air valve pump body positioning tool 12 can be loosened.
