Description
Technical Field
The invention relates to the technical field of electromagnetic valve production and processing equipment, in particular to a winding device for electromagnetic valve production and a working method thereof.
Background
The electromagnetic valve is used as a core executive component for industrial automation control, and the response speed, the sealing performance and the service life of the valve body are directly determined by the winding precision of the coil. The existing winding device has obvious technical defects in the electromagnetic valve skeleton positioning link, and is concentrated on the two major core problems of insufficient front end limiting functionality and missing top limiting structure, so that the mass production efficiency and the yield of the high-precision electromagnetic valve are restricted.
The traditional fixture generally adopts a fixed limiting block to restrict the electromagnetic valve skeleton in the horizontal direction, but in order to avoid mechanical interference between a winding main shaft and the fixture, a larger avoiding space is reserved for the limiting block. This design results in a solenoid valve skeleton that can be accurately positioned only when the dimensions are perfectly matched, with minimal adaptability to small dimensional deviations. The electromagnetic valve skeleton is easy to deflect or even collide in the placing or conveying process, the winding precision is affected if the electromagnetic valve skeleton is light, and the electromagnetic valve skeleton is deformed or the main shaft is damaged if the electromagnetic valve skeleton is heavy.
Because the manipulator needs to place the solenoid valve skeleton perpendicularly from the top, current anchor clamps can't set up rigid limit structure at the top, rely on solenoid valve skeleton dead weight and bottom sprag to realize vertical positioning alone. Under the action of high-speed movement or winding tension, the electromagnetic valve framework is easy to shake. Part of schemes try to assist in fixing through vacuum adsorption or lateral clamping jaws, but the vacuum adsorption has severe requirements on the surface flatness of the electromagnetic valve framework, the lateral clamping jaws easily interfere with a manipulator path, and the suitability of the electromagnetic valve framework is insufficient.

S1, feeding, namely placing the electromagnetic valve framework in a placing groove from top to bottom by a feeding mechanism, supporting the electromagnetic valve framework by the bottom surface of the placing groove, and limiting the electromagnetic valve framework in the horizontal direction by a rear side surface, two side surfaces and two front end limiting blocks to prevent displacement;

When the electromagnetic valve framework is placed, the spring is reset to enable the limiting block to be retracted, the horizontal position of the electromagnetic valve framework is self-adaptively restrained through the large-area contact surface, the electromagnetic valve framework can be accurately limited even if size deviation exists, and deflection or collision caused by traditional rigid limiting is avoided.
2. The interference matching structure of the top limiting block breaks through the defect that the traditional top is unconstrained. When the electromagnetic valve framework is lowered, the top limiting block and the annular block at the front end of the electromagnetic valve framework form elastic interference fit, so that the offset in the vertical direction is close to zero. Because the front end annular block of the electromagnetic valve framework is generally of an annular structure, the annular block can clamp the electromagnetic valve framework in the center of the placing groove from the side end while the top end is limited. The non-rigid contact design effectively avoids rigid extrusion, ensures positioning accuracy and reduces potential damage to the solenoid valve framework.
