Description

A kind of automatic embedding instrument and encapsulating device
Technical field
The present invention relates to experiment instrument fields, in particular to a kind of automatic embedding instrument and encapsulating device.
Background technique
Nucleic acid by many nucleotide polymerizations at large biological molecule compound, be life one of most basic substance.Nucleic acid It is widely present in all animal and plant cells, in microbial body, the intracorporal nucleic acid of biology often forms nucleoprotein in conjunction with protein.No Same nucleic acid, the differences such as chemical composition, nucleotidesequence.At present when detection of nucleic acids is tested, reaction solution will be mounted in advance In PCR pipe or deep-well plates, PCR pipe adds reaction solution and capping to be mostly manual operations.
Inventor has found that the liquid feeding lid lid arrangement of existing PCR pipe at least has the disadvantage in that existing under study for action The liquid feeding lid lid arrangement of PCR pipe complex steps and is easily damaged PCR pipe when closing PCR pipe.
Summary of the invention
The purpose of the present invention is to provide a kind of automatic embedding instruments, to improve the liquid feeding lid lid arrangement of existing PCR pipe There are deviations for liquid feeding, liquid volume added, and complex steps, ineffective problem when closing PCR pipe.
The purpose of the present invention is to provide a kind of encapsulating device, with improve existing PCR pipe liquid feeding lid lid arrangement liquid feeding, There are deviations for liquid volume added, and complex steps, ineffective problem when closing PCR pipe.
The present invention is implemented as follows:
Based on the first above-mentioned purpose, the present invention provides a kind of automatic embedding instruments, including close lid mechanism, fluid injection automatically The circumferential direction of mechanism and mounting base for installing PCR pipe, the automatic pass lid mechanism and the mechanism for filling liquid along the mounting base Interval setting, the output end of the mechanism for filling liquid are located at the opening of the PCR pipe, and the output end of the automatic pass lid mechanism turns The PCR pipe is closed after dynamic.
The liquid feeding lid lid arrangement of existing PCR pipe is all divided into two steps to the closing of PCR pipe, and first first rolls up lid It going, second step, which is only, compresses lid, this mode complex steps, and when compressing lid, since pressure is larger, easy pair PCR pipe damages.Automatic embedding instrument provided by the invention closes PCR pipe by the way of rotation, only needs one Step can close PCR pipe, and mode of operation is simple and fast, the working efficiency greatly improved, and automatic pass lid mechanism is defeated Outlet flips up, and finally change into lid on tube body in rotation with lid, automatic during this to close the defeated of lid mechanism Outlet is contacted with lid always, can be effectively reduced impact force when closing lid, be avoided causing to damage to PCR pipe.
Further, the PCR pipe includes tube body and lid, and the lid is connected to the tube body by flip mode lid, The lid opens the rear lid and the lid be located at the mounting base it is same diametrically, the diameter is first directly Line.
In fluid injection, lid in opened condition, when tube body goes to the lower section of mechanism for filling liquid output end, from mechanism for filling liquid to Liquid is injected in tube body, when the tube body for being marked with liquid goes to the automatic position for closing lid mechanism, since lid and tube body are located at peace Filling seat same, diametrically lid is located exactly at the top of the automatic output end for closing lid mechanism at this time, opens when closing lid mechanism automatically When beginning to rotate, lid is rotated therewith, and finally lid is connected on tube body.
Further, the automatic pass lid mechanism includes motor, mounting blocks and closes cover, described in motor driven connection Mounting blocks, the pass cover are installed on the mounting blocks, and the pass cover rotates together the installation with the mounting blocks The rotational axis line of block is vertical with the first straight line.
After closing cover overturning 180 degree, cover cap can be connect on tube body.
Further, the pass cover includes link block and elastic component, and one end of the link block is installed on the installation Block, the elastic component are located at the one end of the link block far from the mounting blocks.
Elastic component can reduce the impact force caused by PCR pipe when closing lid, connect when on tube body by cover cap, lid After reaching above tube body, the top that can be stuck in tube body can not continue to move down, and after cover continues increase to the power of lid when pass, close lid Power reaches a critical point, and section shifting can occur suddenly for lid at this time, then covering on tube body tightly, and lid is in unexpected position After shifting, close cover can also be displaced a distance suddenly therewith, then collide with PCR pipe, setting elastic component can buffer because The impact force that this refitting generates.
Further, the link block is in bar shaped, and the cross section of the link block is in semicircle, and the link block with it is described Mounting blocks are coaxial.
The volume of link block in this way can be set smaller, link block rotate 180 degree after, located immediately at tube body just on Side, the lesser words of link block at work will not impact adjacent PCR pipe.
Further, the elastic component is elastic slice, and the elastic slice includes bending part and straight portion, and the bending part is installed on institute Link block is stated, the straight portion is located at the one end of the bending part far from the link block, and the convex surface of the bending part is described in The rotational axis line of mounting blocks.
There is straight portion to apply pressure to lid to carry out closing lid movement, a cushion effect is formed by bending part.
Further, the straight portion along far from the mounting blocks axial line direction with a distance from the link block gradually Become larger.
Preferably impact force can be buffered in this way.
Further, the bending part is mounted on the mounting blocks by bolt.
Bending part, which is connect by bolt with mounting base, to impact the elastic force of bending part.
Further, the mounting base includes driving mechanism and mounting disc, and the driving mechanism is drivingly connected the installation Disk, the mounting disc are rotated along its axial line, and the PCR pipe is set as multiple, week of multiple PCR pipes along the mounting disc It is arranged to interval.
Multiple PCR pipes are rotated along mounting disc, are formed flow line production, can be promoted operating efficiency.
Based on the second above-mentioned purpose, the present invention also provides a kind of encapsulating devices, including automatic embedding as described above Instrument.
The automatic embedding instrument of encapsulating device provided by the invention closes PCR pipe by the way of rotation, only needs One step can close PCR pipe, and mode of operation is simple and fast, and the automatic output end for closing lid mechanism is in rotation, with Lid flips up, and finally changes into lid on tube body, and automatic output end for closing lid mechanism connects with lid always during this Touching can effectively reduce impact force when closing lid, avoid causing to damage to PCR pipe.
Compared with prior art, the beneficial effect that the present invention realizes is:
Automatic embedding instrument provided by the invention closes PCR pipe by the way of rotation, only needs a step just PCR pipe can be closed, mode of operation is simple and fast, and the automatic output end for closing lid mechanism is in rotation, with lid to turning over Folding, and finally change into lid on tube body, automatic output end for closing lid mechanism is contacted with lid always during this, can be effective Reduce impact force when closing lid, avoids that PCR pipe is caused to damage.
