Abstract

The invention discloses an automatic oscillation mixing device for sample pretreatment, and belongs to the technical field of experimental instruments. The device comprises a rack, a voice coil motor,a sliding seat, a position measurement sensor, a rocker, a sample tube clamp mechanism and a controller, wherein the voice coil motor is fixed on the rack; the voice coil motor is vertically connected with the sliding seat; the position measurement sensor is arranged on the sliding seat, the rocker is pivoted on the rack, the sliding seat is rotatably connected with the head end of the rocker, ashort arm is arranged from the head end of the rocker to the pivoted part, a sliding gap parallel to the short arm is reserved at the rotary joint, the sample tube clamp mechanism is fixed at the tailend of the rocker, and a long arm is arranged from the tail end of the rocker to the pivoted part; and the controller is connected with the voice coil motor and the position measurement sensor. The scheme has the characteristics of artificial oscillation simulation and dynamic adjustment, can realize electronic buffering, reduces mechanical impact at the tail end of a reciprocating motion stroke,improves an up-down reciprocating oscillation stroke and output force, reduces noise generation, and is light in overall structure.

Description

Technical field

[0001] The invention relates to the technical field of experimental instruments, in particular to an automatic oscillation mixing device for sample pretreatment. Background technique

[0002] As we all know, many samples in the laboratory need to be mixed by shaking. The traditional shaking method is generally that the operator holds the sample tube in his hand and swings his arm up and down to oscillate and mix the sample in the sample tube. This method of operation will cause operation The high-intensity labor of personnel, once encountered a large number of oscillating samples, it requires multiple operators to complete it, not only the labor cost and time cost increase, but also the work efficiency is not high.

[0003] There are already some oscillating mixing devices on the market that replace the manual oscillating and mixing of the sample tube, and can realize multi-channel simultaneous oscillating mixing. Only one operator can complete batch sample oscillat...
