| description | The invention discloses a sample double-needle sample adding device and a control method. A first sample needle and a second sample needle can be driven by a sample adding needle driving assembly to perform independent vertical movement respectively, and the double needles can be in contact with the liquid level simultaneously or independently according to control requirements. Through the liquidlevel sensing assembly, the detection and feedback of the vertical movement position of the sample needle can be realized. Through the anti-collision module, the sample needle can be prevented from being damaged when vertical collision occurs to the sample needle. The sample double-needle sample adding device is arranged in a high-speed biochemical analyzer. The double-needle independent sample adding mode is adopted, the problems that double-needle overhead liquid discharging and sample adding have high requirements for a liquid path system and sample adding is unstable can be solved. Meanwhile, due to the fact that |
