Automatic cover opening device for sample container

Abstract

The invention discloses an automatic cover opening device for a sample container. The automatic cover opening device comprises a rack, a clamping mechanism, a cover opening mechanism and a lifting mechanism, wherein the clamping mechanism is arranged on the rack and used for fixing and clamping the sample container and preventing the sample container from rotating and moving in the axial direction, the cover opening mechanism is arranged on the clamping mechanism and used for taking down a sample container cover, and the lifting mechanism is arranged on one side of the rack and used for driving the cover opening mechanism to ascend and descend. The automatic cover opening device further comprises a rotating mechanism and a waste cover recycling mechanism, wherein the rotating mechanism is connected with the cover opening mechanism and used for driving the cover opening mechanism to clamp and rotate the sample container cover, and the waste cover recycling mechanism is arranged on one side of the bottom of the rack and used for recycling the sample container cover taken down by the cover opening mechanism. According to the automatic cover opening device, clamping and rotating of the sample container cover can be achieved without two independent driving mechanisms, only a power-source-free cover opening head is arranged based on the sample container cover rotating mechanism, high cost is avoided, the number of fault points is reduced, and therefore the economic benefit is increased.

Description

technical field

[0001] The invention relates to a cover-opening device in the field of medical instruments, in particular to an automatic cover-opening device for sample containers. Background technique

[0002] In the traditional sample container cap removal equipment, the cap or cap of the sample container, in the state where the container body is held by the holder, is clamped by the distal part of the cap removing mechanical arm and pushed upward by the lifting mechanism, thereby automatically Remove the cover. However, the function of traditional sample container removal equipment is not perfect, and there are the following problems in use and cost: 1. Screw caps with different pitches cannot be removed, and sample containers of different specifications and sizes cannot be adapted. 2. The method of rotating the sample container to remove the screw cap has a complex structure and many power sources, and there is a risk of damaging the clamping stability of the sample co...
