Abstract

The invention belongs to the technical field of automotive trim material detection, and discloses an automotive trim material VOC release detection device, which comprises: a rotary support frame; the detection cabin assembly is rotatably mounted on the rotary supporting rack, the detection cabin assembly comprises a main box body and a sealing cover mechanism, and the main box body and the sealing cover mechanism are matched to form a closed detection cavity; and the suspension clamping assembly is arranged in the detection cavity and is used for clamping the sheet-shaped detected material and physically dividing the detection cavity into a first chamber and a second chamber. An oil-free pump suction mechanism is matched with a corrugated pipe buffer mechanism to construct a breathing circulation system, gas is driven to penetrate through a tested material in a reciprocating mode, a vibration excitation medium is accumulated on the surface of the material by means of gravity in combination with a rotary inversion structure, circulating vibration excitation of fluidization suspension and compaction contact is generated under the action of alternating airflow, and the test precision is improved. Therefore, a gas boundary layer is effectively destroyed under the action of microscopic hammering and friction, and the deep VOC desorption rate and detection authenticity are remarkably improved.
