Description

A kind of assembly method of micro part
Technical field
The invention belongs to Fine Boring technical field, relate to a kind of assembly method of micro part.
Background technology
Fine Boring is the key in accurate microminiature product manufacturing, in recent years, is studied and achieves certain achievement both at home and abroad for the automatic setup system of micro part and assembly method.But comparatively large for size span, shape is different and have the Fine Boring of multiple micro parts of relative position, Gesture, as the hard parts that large-scale part is tens millimeters, small size part is the flexible part of several millimeters, traditional assembly method is the part that first fitted position is relatively large, and then is got on by Assembly of the parts less for size.Adopt this assembly method, the part position that after in assembling process, the size of assembling is less is not easily fixed and easy stressed generation disturbance deformation, thus causes its assembly precision lower.
Summary of the invention
For fixing micro part, reduce disturbance deformation, improve the assembly precision of micro part, the invention provides a kind of assembly method improving micro part assembly precision.This assembly method comprises a set of assembling device, can be realized the assembling process of micro part by this assembling device.Micro part comprises three parts, the cuboid part that wherein part A, B is size, shape is identical, and full-size place is no more than 4mm, and minimum dimension place is no more than 0.05mm; Part C is triangular supports structure, and longest edge is no more than 20mm.
(1) assembling device is built.Assembling device comprises part material loading seat, is mounted with seat, assembling jig base, fixture gas circuit connect base, vacuum generating device, adjustment pressing plate, the left and right axis of guide and tightening knob.Its position relationship is: part material loading seat be mounted with a level and be placed on assembling jig base, have interval between the two.Assembling jig base connects base with fixture gas circuit and connects, and fixture gas circuit connects base and communicates with vacuum generating device, forms vacuum suction gas circuit.The left and right axis of guide is placed in part material loading seat and the both sides being mounted with seat respectively.
(2) first part to be assembled is placed on part material loading seat during assembling.Arrange two diametric hole respectively at the right and left being mounted with seat, two diametric hole spacing are 7mm, are no more than the bottom side length of tripod.In assembling process, from part material loading seat, holding parts A, B are placed in the diametric hole of Assembly of the parts base respectively, open vacuum absorption device, part A, B absorption are fixed;
(3) holding parts C moves to the top of Assembly of the parts pedestal, horizontal positioned and ensure to align with part A, B respectively in the Liang Ge angle, base of this triangular supports;
(4) adjustment pressing plate is arranged on the axis of guide, uses tightening knob it to be depressed gently, make part C and part A, B glued together, assembling end.
Effect of the present invention and benefit change traditional assembling strategy, first assembles micro part, refill the part of joining large-size, reduce the disturbance to micro parts.This assembly method can improve the assembly precision of part, accelerates assembling process, enhances productivity.
Accompanying drawing explanation
Fig. 1 is assembling jig cell schematics.
Fig. 2 is mounted with base schematic diagram.
In figure: 1 right tightening knob; 2 adjustment pressing plates; The 3 right axis of guides; 4 size parts; 5 are mounted with base; 6 assembling jig bases; 7 fixture gas circuits connect base; 8 right micro parts; 9 pickup Attraction blocks; 10 left micro parts; 11 left tightening knobs; The 12 left axis of guides; 13 part material loading seats; 14 left diametric hole; 15 right diametric hole.
Detailed description of the invention
Specific embodiment of the invention case is described in detail below in conjunction with technical scheme and accompanying drawing.
The first step: size parts 4 to be assembled, right micro part 8, left micro part 10 are placed in part material loading seat 13;
Second step: mobile mechanical arm makes clamp be positioned at above tool stand, controls clamp folding, makes its gripping adsorb syringe needle.Control manipulator motion, the clamp of the absorption of gripping syringe needle is moved to part material loading seat 13, opens vacuum generating device, adsorb the right micro part 8 be positioned on part material loading seat 13, and moved to and be mounted with above base 5;
3rd step: right micro part 8 is placed in above the right diametric hole 15 be mounted with on base 5, under the detection of vision system, it is made to keep certain depth of parallelism with the edge being mounted with base 5, open vacuum generating device, make the right diametric hole 15 one-tenth vacuum state be mounted with on base 5, adsorb and fix right micro part 8.
4th step: repeat second step, left micro part 10 is moved to and is mounted with above base 5;
5th step: be placed in by left micro part 10 above the left diametric hole 14 be mounted with on base 5, under the detection of vision system, makes it keep certain depth of parallelism with the edge being mounted with base 5 and right micro part 8.Open vacuum generating device, make the left diametric hole 14 be mounted with on base 5 form vacuum state, adsorb and fix left micro part 10;
6th step: adhesive is put respectively on right micro part 8 and left micro part 10;
7th step: absorption syringe needle is replaced by mobile clamp, and pick up pickup Attraction block 9; Control manipulator motion, the clamp of the pickup of gripping Attraction block 9 is moved to part material loading seat 13, opens vacuum generating device, adsorb the size parts 4 be positioned on part material loading seat 13, and moved to and be mounted with above base 5;
8th step: size parts 4 be placed in and be mounted with above base 5, utilizes the position and attitude of vision system determination size parts 4; Control manipulator motion, make it contact gently with left micro part 10 with the right micro part 8 scribbling adhesive, utilize Micro-force sensor to control contact force size, prevent part from producing deformation;
9th step: first adjustment pressing plate 2 is arranged on the left axis of guide 12, the right axis of guide 3, and be fixed with left tightening knob 11, right tightening knob 1, now, together be fixed on assembling jig unit as keeping the pickup Attraction block 9 of fixture, size parts 4 and pedestal, such pickup Attraction block 9 can play the maintenance effect of position to micro part and attitude, is pressed on one piece with pedestal.After high-temperature process, adhesive generation effect, takes off pickup Attraction block, to ensure that assembly precision is not destroyed, thus achieves the Fine Boring of micro part and pedestal.
