[0002] The air valve pump is an important part of the car, usually used in the vehicle's brake system. In the car's pneumatic or hydraulic brake system, the main function of the air valve pump is to maintain the air pressure in the system stable and ensure the normal operation of the brake system.

[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 air valve pumps, the utility model provides an automatic press-fitting device for electromagnetic valve cores of air pumps. The following technical solutions are adopted:

The test assembly includes an electromagnetic valve core power-on test bench and a downward pressure power-on test device. The electromagnetic valve core power-on test bench is installed on the slider of the electromagnetic valve core transfer linear module. The downward pressure power-on test device is installed on the frame through a gantry and is located above multiple electromagnetic valve core transfer linear modules. When the electromagnetic valve core power-on test bench reaches below the downward pressure power-on test device, it presses down on the electromagnetic valve core to be pressed for power-on test. The press-fitting assembly is installed on the frame and surrounds the outer periphery of the rotating disk of the rotating mechanism. When the air valve pump body positioning tooling rotates to the press-fitting position at the bottom of the press-fitting assembly, multiple electromagnetic valve cores to be pressed are respectively pressed into multiple electromagnetic valve core installation positions of the air valve pump.

[0006] By adopting the above technical scheme, a rotating station design is adopted, and an electric power test is performed on the solenoid valve core to be pressed before the pressing station. The electric power test is realized based on the cooperation of the solenoid valve core electric power test component and the solenoid valve core transfer and placement robot component. The electric power test is performed synchronously without affecting the normal pressing of the pressing component, which can ensure that the solenoid valve core is qualified before pressing. The number of air valve pump body positioning fixtures is six, 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 the transfer robot, the rotating disk of the rotating mechanism rotates clockwise, and the solenoid valve core transfer and placement machine The robot component will place the solenoid valve core to be pressed that has completed the power-on test in 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 specifications of the solenoid valve cores to complete the placement of multiple solenoid valve cores to be pressed into the positions to be pressed; 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 and has high pressing efficiency.

[0007] Optionally, the number of solenoid valve core transfer linear modules and power-on test components are four groups.

The clamping mechanisms are respectively installed on the lifting parts of the four lifting drive mechanisms. The power-on coil is located at the clamping part of the clamping mechanism and moves up and down with the clamping part. When the power-on coil is pressed down to contact the solenoid valve core to be pressed, the solenoid valve core to be pressed is energized, the test air circuit is connected to the air circuit of the solenoid valve core to be pressed, and the flow detection switch realizes the power-on test of the solenoid valve core to be pressed by detecting the flow of the test air circuit.

[0008] By adopting the above technical scheme, four groups of solenoid valve core transfer linear modules 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 can be driven by electric cylinders, which can align the energized coil with the on-potential of the solenoid valve core to be pressed, and realize the power-on test. After power-on, compressed gas is delivered to the air circuit integrated on the solenoid valve core power-on test bench through the test air circuit. The flow detection switch can detect the gas flow. If it is judged that the solenoid valve pump to be pressed can normally output the set gas volume, it is judged that the solenoid valve core power-on test is qualified.

[0016] By adopting the above technical scheme, the pressing of the press-fitting component is achieved based on the pressing electric cylinder mechanism driving the pressing rod to press down. 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.

[0017] Optionally, a visual inspection component is also included, which is located above the rotating disk of the rotating mechanism and is used for visually inspecting whether the multiple solenoid valve core installation positions of the air valve pump to be press-installed are all placed with the solenoid valve cores to be press-installed.

[0046] The rotary station design is adopted, and the solenoid valve core to be pressed is subjected to an electric-on test before the pressing station. The electric-on test is realized based on the cooperation of the solenoid valve core electric-on test component and the solenoid valve core transfer and placement robot component. The electric-on test is carried out synchronously without affecting the normal pressing of the pressing component, so as to ensure that the solenoid valve cores are qualified before pressing.

[0056] 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.
