Online four-way valve detecting and sorting device and sealing detection method thereof

Abstract

The invention provides an online four-way valve detecting and sorting device and a sealing detection method thereof. The device comprises a base with an upper frame. A three-axis carrying mechanism is arranged above the base. An automatic chain plate line is arranged on one side of the base. A defective product track is arranged on the other side of the base. A test carrier is arranged in the middle of the base, and the test carrier is connected with a test system inside the base. Four-way valves can be grabbed and placed automatically, and it is ensured that incoming four-way valves are located accurately and consistent in direction. Through the fully automatic process, the production efficiency is improved, the product quality is enhanced, and the production cost is reduced. Moreover, automatic location test is realized. For the problem of copper piping deviation of four-way valves, the precision of automatic shaping is high, the test pass rate is high, and the rejection rate is low. The problem of sealing failure caused by product size deviation is avoided.

Description

Technical field [0001] The invention belongs to the technical field of air tightness testing, and specifically relates to an online detection and sorting four-way valve device and a sealing detection method thereof. Background technique [0002] The four-way valve is an important part of the air-conditioning system. The four-way valve is used to change the flow direction of the refrigerant in the air-conditioning system, so as to realize the conversion between the cooling mode and the heating mode of the air-conditioning system. The four-way valve includes a valve core and a valve body. The valve body is provided with four through holes, including through hole D, through hole S, through hole E, and through hole C. The movement of the spool of the four-way valve changes the conduction relationship of the through holes on the valve body. If the valve core moves to the through hole S and the through hole C, the through hole S and the through hole C are the same as the valve core ca...
