Description
Technical field
The present invention relates to a kind of application methods of objective table, are a kind of for processing biochip or experiment briefly
A kind of application method of the overhead type biochip objective table needed.
Technical background
Currently, with the rapid development of IC manufacturing, MEMS, micro-optical device and biochip etc.,
The fixture for being widely used in micro processing field also emerges one after another.The objective table of current general fixture is solid face mostly, to
Processed sample is placed on the face of objective table, and still, the requirement of the special substance for processing biochip is needed in process
Middle holding processing chip can cool down rapidly up and down or need hollow out quarter saturating chip base and cannot damage objective table or
Person needs to absorb the exhaust gas impurity etc. that engraving generates from side rapidly, this require fixture objective table cannot as objective table that
Sample is fabricated to the platform being in close contact with fixture, but is required to keep a distance with fixture, to meet above-mentioned add
The demand of work technique.Meanwhile some biochip requirement of experiment, side loads such as magnetic field, circulation line under the die, it is also desirable to
When chip is fixed, beneath chips are empty.
Therefore, it is necessary to a kind of not only simple and convenient, but also the kinds of processes such as through-carved work for being able to satisfy laser engraving machine need
It asks and a kind of Novel biological chip objective table and its application method of special experiment demand.
Summary of the invention
The main purpose of the present invention is to provide the biologies of the kinds of processes demand such as through-carved work for meeting laser engraving machine
The application method of chip positioning fixture objective table solves fixture objective table in the prior art and is unable to satisfy what technique processing needed
Problem.To achieve the goals above, the present invention provides a kind of application methods of overhead type biochip objective table.
The technical scheme is that a kind of application method of overhead type biochip objective table, the objective table master used
It to be made of the rotating device of base station and adjustment chip hack lever.The base station is in cuboid, inside be processed to it is hollow box-like,
The rotating device of adjustment chip hack lever is installed inside it.The top of rotating device inside base station is connected with stretching base
Platform, be capable of the chip hack lever of repeated removal and installation.Collet adjustment device is installed on chip hack lever, adjusts device in collet
On be connected with collet.The rotating device is made of 4 or more even number four-way balls, or by 2 or more even numbers
The even number pinion gear composition of column gear and 4 or more.It is described below.
A kind of four-way ball rotating device.The even number four-way ball is divided into the identical even number number of rows row of vertical and horizontal
Column, such as: longitudinal 2 rows, lateral 2 rows；Or such as longitudinal 4 rows, lateral 4 rows.Or even number four-way ball is divided into vertical and horizontal
Different even number number of rows arrangement, such as: longitudinal 4 rows, lateral 6 rows；Or such as longitudinal 2 rows, lateral 8 rows.This ensure that uniformly
Pairs of chip hack lever can surround square or rectangle.Four-way ball is the sphere of mutual cooperation processing, same radius, four
To the vertical longitudinal surface of ball, it was machined with the point symmetry right-angled intersection of top dome up and down of four-way ball, direction in space
The longitudinal occlusion groove of the orthogonal circle of plane and the lateral occlusion groove of a circle.The design of longitudinal occlusion groove ensure that phase
The chip hack lever in four-way top dome portion that is adjacent 2 occlusions or being separated by even number can longitudinally while inwardly or outwardly tilt identical
Angle；Laterally the design of occlusion groove ensure that the chip hack lever in four-way top dome portion that is adjacent 2 occlusions or being separated by even number
It can laterally while inwardly or outwardly tilt equal angular.The meaning for being separated by even number is exactly four-way ball between two four-way balls
Quantity be even number, such as: 2,4,6,8,10 etc..Longitudinal occlusion groove and the laterally processing of occlusion groove are to guarantee whole four
When being interlocked to ball initialization, the vertical axes of top dome point keep the vertical same horizontal plane above and below each four-way ball, and
And the vertex of the vertical axis direction of four-way ball, on the same horizontal plane, chip hack lever is mounted in adjacent four-way ball or is separated by
The vertical axes of even number four-way ball are apicad on position.The occlusion design of longitudinal occlusion groove and laterally occlusion groove, limits
Four-way ball can only with the front and back of the vertical axes through upper and lower vertex is longitudinal, left and right lateral drift and rotate.It ensure that when cross
When tilting 1 chip hack lever thereon to 1 four-way ball of rotation, it can all be driven vertical because of the interlocking of longitudinal occlusion groove
To the equidirectional lateral rotation of four-way ball of adjacent or longitudinally spaced even number, tilt the chip hack lever at the top of it in the same direction；Together
When because laterally occlusion groove interlocking, make corresponding to this few four-way ball rotate in same direction it is other it is laterally adjacent,
Or the four-way ball of laterally spaced even number rotates backward, the lateral inclination for the chip hack lever opposite direction for driving them to push up.Similarly,
When longitudinally rotating the 1 chip hack lever of 1 four-way ball inclination thereon, the chip hack lever that can link in other four-way top dome.Chip
Collet adjustment device on hack lever ensure that the folder that any of the above links, on chip hack lever in the design of same level
Head adjustment device and collet remain in same level.
Another gear driving device.The column gear is long column shape, damaged surface processing be parallel to axis of a cylinder,
That is the tooth of gear shaft, even number column gear, which is mutually twisted, to be horizontally arranged inside base station, even number, ensure that adjacent 2 are stung
When column gear rotation closing or being separated by even number, top longitudinally forward or can tilt backwards equal angular simultaneously.Column
Gear internal is the hollow gear for having gear hub and cavity；Gear shaft side is equipped with a row and is vertically arranged in the same space
The pinion gear of plane, space plane where the pinion gear being vertically arranged are parallel to the gear shaft and vertical pillar tooth of column gear
Wheel is mutually twisted horizontal positioned horizontal plane.Even number pinion gear divides arranged in rows according to the quantity of column gear, even number,
When ensure that pinion rotation that is adjacent 2 occlusions or being separated by even number, top can laterally to the left or be tilted to the right simultaneously
Equal angular.The several pinion gears of one parallelism and antithesis are packed into inside 1 column gear.Namely one is equipped with inside each column gear
The several pinion gear of parallelism and antithesis.Be separated by even number the meaning be exactly two gears between column gear or pinion gear quantity be
Even number, such as: 2,4,6,8,10 etc..Even number ensure that column gear that is adjacent 2 occlusions or being separated by even number, inside
It is adjacent 2 occlusion or be separated by even number pinion gears at the top of chip hack lever, can with column gear longitudinally rotate and
The lateral rotation of pinion gear, it is vertical or horizontal while inwardly or outwardly tilting equal angular.Chip hack lever is mounted in adjacent small
Gear is separated by the gear vertex position of even number pinion gear, collet on chip hack lever adjustment device in same level,
It ensure that any of the above links, the collet adjustment device and collet on chip hack lever remain in same level.
