Abstract

The invention discloses an optocoupler assembly and a sample adding assembly applying the same, the optocoupler assembly comprises an optocoupler separation blade and an optocoupler, an elastic part is arranged between the optocoupler and the optocoupler separation blade. The sample adding assembly using the optocoupler assembly comprises a peeling valve, an injection device, a driving device andthe optocoupler assembly, the injection device is connected with the peeling valve, a push plate is arranged between the driving device and the injection device, the push plate is connected with the injection device, a trigger switch is arranged on the push plate, the optocoupler assembly is used for controlling the driving device, the trigger switch is used for triggering the optocoupler assembly, the requirement for guiding precision is low. The sample adding assembly applying the optocoupler assembly comprises the peeling valve, and the injection device is connected with the peeling valve;the push plate is arranged between the driving device and the injection device, the push plate is connected with the injection device, the push plate drives the injection device, the injection deviceis used for sucking and discharging liquid through a rotary cut valve, and a trigger switch is arranged on the push plate. Accoringd to the optocoupler assembly, the trigger switch is used for triggering the optocoupler assembly, and the optocoupler assembly is used for controlling the driving device.

Description

technical field [0001] The invention is used in the field of hydraulic systems, and in particular relates to an optocoupler assembly and a sample adding assembly using the same. Background technique [0002] At present, the optocoupler of the common sampling components is integrated on the control board, and the optocoupler block is fixed on the push plate. During use, the push plate is required to drive the optocoupler block to run and trigger the optocoupler. The machining accuracy and system guidance accuracy are extremely demanding, and a slight deviation will cause the optocoupler block to fail to trigger the optocoupler. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes an optocoupler assembly and a sample loading assembly using the same, which have lower requirements on guiding precision. [0004] In the first aspect, an embodiment...
