Single pipe grabbing control system under deep hypothermia cold chain environment

Abstract

The invention belongs to the technical field of single pipe grabbing, and particularly relates to a single pipe grabbing control system in a profound hypothermia cold chain environment. The single pipe grabbing control system in the deep hypothermia cold chain environment is good in using effect. The single tube grabbing control system in the deep hypothermia cold chain environment comprises a processor circuit, a first stepping motor driving circuit, a second stepping motor driving circuit, a third stepping motor driving circuit, a heating control circuit, a temperature detection circuit and a power supply circuit. The control circuit is characterized in that a signal transmission port of the processor circuit is respectively connected with a signal transmission port of the first stepping motor driving circuit, a signal transmission port of the second stepping motor driving circuit, a signal transmission port of the third stepping motor driving circuit, a signal transmission port of the heating control circuit and a signal transmission port of the temperature detection circuit.

Description

technical field [0001] The invention belongs to the technical field of single-pipe grabbing, and in particular relates to a single-pipe grabbing control system in a cryogenic cold chain environment. Background technique [0002] There are two existing sample tube grabbing techniques. The first is grabbing from the outside of the sample tube cap. Some manufacturers are currently using this method, which is mostly seen in storage systems accessed in the form of SBS racks. The second is to grab from the inside of the sample tube cap. Due to the design of the concave structure in the middle of the sample tube cap, this grabbing method becomes the mainstream grabbing method. [0003] Among the existing sample tube grasping technologies, the first method of grasping from the outside of the sample tube cap has a relatively large limitation on the space, and it is easy to hit the surrounding sample tubes when grasping, which may cause damage to the sample. possible. The second met...

[0003] In the existing sample tube grabbing technology, the first method of grabbing from the outside of the sample tube cap has relatively large space limitations, and it is easy to hit the surrounding sample tubes when grabbing, resulting in impact and damage to the sample possibility of

The second method of grasping from the inside of the sample tube cap often causes tube jamming or tube drop accidents, requiring manual intervention to avoid sample loss, and the claw head is slightly worn, so it cannot be grasped normally
