Precise automatic assembling and detecting system for valve element assembly

Abstract

The invention relates to the field of automation equipment, and particularly discloses a precise automatic assembling and detecting system for a valve element assembly. The precise automatic assembling and detecting system for the valve element assembly comprises a feeding area, an assembling area, a welding area, a rechecking area and a discharging area which are divided according to a processing sequence, and is characterized in that components in the assembling area are improved; and the assembling area comprises a mounting base, a displacement servo mechanism, a laser micrometer, an infrared temperature measuring instrument, a pressure sensor and a controller. The lift and the temperature are measured in a non-contact mode, the assembling precision is improved, and the temperature can be used for correcting the lift; and the measurement speed is high, the measurement is accurate, the efficiency is high, the requirement for the proficiency of an operator is reduced through a computer control mode, and frequent operation of the operator is not needed. A pressure sensor is added, and a pressure-displacement curve is introduced, so that the assembling quality can be further judged.

Description

technical field [0001] The invention belongs to the field of automation equipment, in particular to a precision automatic assembly and detection system for a valve core assembly. Background technique [0002] The spool component assembly of the high-speed solenoid valve is a key process in the production process of the solenoid valve. The assembly quality of the spool component directly affects the performance of the solenoid valve. The traditional assembly method mostly adopts semi-automatic or multi-station automatic assembly, which is difficult to meet the assembly quality at the same time. The two key conditions are assembly speed and assembly speed. The spool assembly is composed of a magnetic core, spool, valve seat and return spring. The assembly gap between the spool and the magnetic core determines the lift of the spool. The traditional method uses the contact method. Measuring the amount of movement of the spool, relying on the feedback of the amount of movement, t...

[0002] The spool component assembly of the high-speed solenoid valve is a key process in the production process of the solenoid valve. The assembly quality of the spool component directly affects the performance of the solenoid valve. The traditional assembly method mostly adopts semi-automatic or multi-station automatic assembly, which is difficult to meet the assembly quality at the same time. The two key conditions are assembly speed and assembly speed. The spool assembly is composed of a magnetic core, spool, valve seat and return spring. The assembly gap between the spool and the magnetic core determines the lift of the spool. The traditional method uses the contact method. Measure the movement of the spool, rely on the feedback of the movement, and then control the movement mechanism to adjust the assembly distance, the adjustment speed is very slow, and the measurement process is caused by the heating of the coil, which also causes problems such as large contact measurement errors, resulting in bottlenecks in production efficiency
