Description

Sucked type gripping structure
Technical field
The present invention relates to the reaction tube shifting device technical field of full-automatic Medical Devices, and in particular to a kind of sucked type is grabbed Hand structure.
Background technology
In full-automatic Medical Devices, when reaction tube is transferred into another place by one, claw handgrip is generally used, The handgrip of this structure, such as be typically provided to three-jaw structure, although can also complete the crawl and movement to reaction tube, but this Handgrip is planted to carry out in the presence of the process contacted with reaction tube produces chucking power by three claws to reaction tube body, Certain pretightning force necessarily is caused to the body of reaction tube, it is easy to leave " scratch " on (interior) wall outside reaction tube, be unfavorable for pair Reaction tube is reused, and even results in the damage of reaction tube;And this claw handgrip requires the structure and reaction tube of clamping part Contact surface realize accurate laminating, precise positioning could be preferably realized, it is ensured that the accurate movement of reaction tube, to equipment requirement It is high.
The content of the invention
The present invention can be accurately positioned for the above-mentioned deficiency of prior art there is provided one kind, and reaction tube will not be caused Damage, prevents from outside reaction tube leaving " scratch " on (interior) wall so that the high sucked type gripping structure of reaction tube repeat usage.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is:A kind of sucked type gripping structure, including rise Descending mechanism and sucker gripper mechanism;
Described upgrading mechanism includes lifting base, is arranged at the riser guide on lifting base, is slidably matched with guide rail Sliding block, motor, the driving wheel being connected with driving motor output shaft, by transmission belt and driving wheel be connected it is driven Transmission belt contiguous block is fixed with wheel, described transmission belt;
Described sucker gripper mechanism includes handgrip sucker fixed block, handgrip sucker fixture, handgrip sucker, stage clip, axle With circlip and airway tube;Described handgrip sucker fixture is axially sleeved in handgrip sucker fixed block, described handgrip Sucker is axially sleeved in handgrip sucker fixture, and handgrip sucker fixture is provided with circumferential recessed on the lateral wall of upper end Groove, handgrip sucker fixed block is connected by the circlip for shaft being arranged in circumferential recess with handgrip sucker fixture;It is described Handgrip sucker fixed block and handgrip sucker fixture between be provided with stage clip;Described airway tube is axially sleeved on handgrip sucker In handgrip sucker fixture, and extend handgrip sucker fixture upper end;
Described sliding block and transmission belt contiguous block are fixedly connected with handgrip sucker fixed block respectively.
Using said structure, handgrip sucker fixed block is fixed on elevating mechanism, driving wheel is driven by motor Rotate, then transmission V belt translation is given and transmission belt contiguous block is secured in driven pulley rotation, transmission belt, and transmission belt contiguous block and cunning Block is fixedly connected with handgrip sucker fixed block, then handgrip sucker fixed block moves up and down under the drive of transmission belt contiguous block, with Its sliding block being fixedly connected then does smooth up and down motion along guide rail, then drives whole sucker gripper mechanism to move up and down, When needing adsorption reaction pipe, elevating mechanism drives handgrip sucker to move downward, and handgrip is being run to i.e. into contact with reaction tube During upper surface, continuation runs downwards certain stroke, and elastic deformation occurs for stage clip, and release elastic force is compressed to handgrip sucker fixture, Certain pretightning force is provided by stage clip so as to realize, handgrip sucker is brought into close contact with reaction tube upper surface;Recycle true Empty pump is connected with airway tube, by airway tube abstraction reaction inner air tube, is made to form certain negative pressure in reaction tube, is opened by pressure Close, effectively control is carried out rationally to negative pressure pressure in reaction tube, when reaching expecting pressure in reaction tube, handgrip rises, moved to Need at placing response pipe, drop to reaction tube placing height, then, handgrip arm swing certain angle allows reaction tube and putting hole Side wall collision, causes handgrip sucker certain gap occur with reaction tube upper surface, allows air to enter reaction tube.Now, reaction tube Interior negative pressure is disappeared, under gravity, and reaction tube is fallen into reaction tube loading position hole, and handgrip resets, and prepares crawl work next time. The present invention completely by negative pressure to reaction tube carry out crawl movement, without as claw handgrip to the outer wall or inwall of reaction tube Apply chucking power, so that reaction tube will not be caused damage, prevent from outside reaction tube leaving " scratch " on (interior) wall so that reaction Pipe repeat usage is high, and can also be accurately positioned.
Transmission-type is provided with preferably, being provided with described transmission belt contiguous block on projection, described lifting base Optical interruption device, and when transmission belt contiguous block is close to transmission-type optical interruption device, described projection is located in transmission-type optical interruption device.
Preferably, described handgrip sucker include the disk body section fitted with the reaction tube mouth of pipe and with handgrip sucker fixture The shaft sleeve part of connection, described shaft sleeve part is sleeved in handgrip sucker fixture;The external diameter of described disk body section is more than or equal to The external diameter of the reaction tube mouth of pipe, the height of described shaft sleeve part is less than the height of handgrip sucker fixture;Use said structure can be with Guarantee sucker is fully adsorbed on the mouth of pipe of reaction tube, the combination dynamics of raising and reaction tube, and the height of shaft sleeve part is less than in addition The height of handgrip sucker fixture, can terminate sucker weight, prevent absorption from coming off, and save material.
It is handgrip sucker prepared by elastomeric material as further preferred, described handgrip sucker, can using the structure To realize the damage with the soft contact of reaction tube, reduction to reaction tube, while the close of sucker and reaction tube can also be improved effectively Seal effect, improve absorption dynamics.
Preferably, the lower surface of described airway tube is concordant with the lower surface of handgrip sucker;Can be to prevent using the structure Only airway tube touches reaction tube.
Preferably, described handgrip sucker fixture includes round plate and beam barrel portion, described beam barrel portion, which is sleeved on, grabs In hand sucker fixed block, described round plate stretches out in the lower end of handgrip sucker fixed block, and the external diameter of round plate is more than sucker The external diameter of fixed block;The disk body section of the handgrip sucker is located in round plate, and lower end slightly protrudes from the lower end of round plate;Using Said structure, realizes the connection of handgrip sucker and handgrip sucker fixed block, and ensures the steady of handgrip sucker fixture position simultaneously It is qualitative, it will not be moved up and down with respect to handgrip sucker fixture, while be located at using disk body section in round plate, and lower end is slightly protruded from The lower end of round plate prevents reaction tube from being contacted firmly with handgrip sucker fixture, effectively damage of the reduction to reaction tube.
