Solenoid valve coil assembly pin welding method and equipment

Abstract

The invention relates to the technical field of solenoid valve production, in particular to a solenoid valve coil assembly pin welding method and equipment. The equipment comprises a workpiece positioning seat, a material moving device, a first welding device, a coil assembly testing device, a second welding device, a material moving and overturning device and a turntable stamping detection device; the material moving device is arranged on one side of the workpiece positioning seat, and the first welding device, the coil assembly testing device and the second welding device are sequentially arranged on the other side of the workpiece positioning seat in the machining direction; and a second welding station is connected with one end of a material moving and overturning device, and the other end of the material moving and overturning device is connected with the feeding end of the turntable stamping detection device. Welding operation is divided into the first welding station and the second welding station, the welding efficiency is improved, welded workpieces directly enter the rotary disc stamping detection device to be stamped, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of solenoid valve production, in particular to a method and equipment for welding the pins of a solenoid valve coil assembly. Background technique [0002] The solenoid valve coil assembly includes a skeleton body and a lower cover. The middle part of the skeleton body is columnar and is wound with wires, and the upper end and the lower end of the skeleton body are respectively provided with an upper limit ring and a lower limit ring. The lower part of the wire is limited by the lower limit ring. The upper part of the wire passes through the upper limit ring, and the upper limit ring is provided with a pair of symmetrical pins and a coil assembly. The pin is provided with a first welding point and a second welding point, and the end of the coil component is wound on the end of the pin and welded on the second welding point. The left and right ends of the coil assembly are welded on the first welding point...

AI Technical Summary

Problems solved by technology

[0004] 1. The two processes of welding and stamping require two sets of equipment to be carried out separately. After the workpiece completes a process, it must be unloaded first, then reloaded, and re-positioned, resulting in repeated positioning of the workpiece and reducing production efficiency.

[0005] 2. The shape of the bottom of the workpiece is complex, and it is difficult to locate it with conventional fixtures, and the middle part of the workpiece is wound with wires, which cannot be fixed by manipulator clamping, making it difficult to effectively locate the workpiece

[0007] 4. The frame body and the lower cover are not fixedly connected before stamping, and the middle part of the frame body is wound with wires. When turning over, it is necessary to pay attention not to clamp the wires. This makes the conventional turning device unable to be directly applied to the workpiece, and because the coil Components and pins are irregular in shape, you need to consider how to store them after flipping
