Automatically marking and labelling device of gas tightness detection of heat exchange core body for vehicle

Abstract

The invention relates to an automatically marking and labelling device of gas tightness detection of a heat exchange core body for a vehicle, comprising a gas leakagemeter, a heat exchange core body fixing tool, an electric control system, a marking device and a gas distribution system, wherein a test interface of the gas leakagemeter is connected with a gas pipeline interface arranged on the heat exchange core body fixing tool, the gas distribution system is respectively connected with the marking device and the heat exchange core body fixing frock through a gas inlet pipe and a gas outlet pipe, the gas tightness leakagemeter outputs detection signals to the electric control system, and the electric control system outputs signals to the gas distribution system through calculation to ensure that a pneumatic executor in the marking device acts to drive a mark seal for marking and labelling a tested core body. The invention can realize the function of automatic marking and labelling according to output signals of different leakagemeters, has the universal property on leakagemeter equipment and different tested core bodies, saves the test time on a heat exchange core body, also ensures the reliability of automatic marking and labelling on tested equipment and enhances the production efficiency.

Description

technical field [0001] The invention relates to a marking and marking device for air tightness leak detection of heat exchange cores, in particular to a marking and marking device for air tightness detection of various heat exchange cores in an automobile air conditioning system. Background technique [0002] In the manufacturing process of various heat exchange cores in air-conditioning systems widely used in automobiles at present, the air tightness detection of heat exchange cores is an important link related to product quality. The airtight performance of the heat exchange core not only affects the performance of the car air conditioner, but also directly reflects the function of the main body of the car. The heater core, condenser and evaporator of the automobile air conditioner must undergo strict air tightness tests before leaving the factory to ensure that no leakage occurs during actual use. Therefore, the reliability and automation of the test device The degree di...

AI Technical Summary

Problems solved by technology

The air tightness test leak detectors currently on the market usually only provide the output signal of the test result. The staff must manually mark the tested core body according to the test result during the production process. This process is inefficient and easy to cause artificial Instability and inconsistency of manual labeling

At present, there is no automatic marking and marking device for the air tightness detection of heat exchange cores in the automotive air-conditioning production industry
