Description
Technical field
The invention belongs to accurate mounting technology field, relate to a kind of assembly method of micro part.
Background technology
Accurate assembling is the key during accurate microminiature product is manufactured, and in recent years, has been studied and has obtained certain achievement both at home and abroad for automatic setup system and the assembly method of micro part.But for size span is large, shape is different and have the precision assembling of multiple micro parts of relative position, Gesture, if large-scale part is the hard parts of tens millimeters, small size part is the flexible part of several millimeters, traditional assembly method is the relatively large part of fitted position first, and then Assembly of the parts less size is got on.Adopt this assembly method, the part position that in assembling process, the size of rear assembling is less is difficult for fixing and easy stressed generation disturbance deformation, thereby 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 that improves micro part assembly precision.This assembly method comprises a set of assembling device, can realize the assembling process of micro part by this assembling device.Micro part comprises three parts, and wherein part A, B are the cuboid part that size, shape are 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) build assembling device.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 and connects with fixture gas circuit, 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 respectively part material loading seat and the both sides that are mounted with seat.
(2) while assembling, first part to be assembled is placed on part material loading seat.At the right and left that is mounted with seat, two diametric hole are set respectively, two diametric hole spacing are 7mm, are no more than the bottom side length of tripod.In assembling process, clamp in the diametric hole that part A, B be placed in respectively Assembly of the parts base from part material loading seat, open vacuum absorption device, part A, B absorption is fixed;
(3) clamping part C moves to the top of Assembly of the parts pedestal, horizontal positioned and guarantee that the Liang Ge angle, base of this triangular supports aligns with part A, B respectively;
(4) adjustment pressing plate is arranged on the axis of guide, uses tightening knob that it is depressed gently, make part C and part A, B glued together, assembling finishes.
Effect of the present invention and benefit are to have changed traditional assembling strategy, first assemble micro part, refill the part of joining large-size, have reduced 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 adjust pressing plate; 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 pick up Attraction block; 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.
The specific embodiment
Describe specific embodiment of the invention case in detail below in conjunction with technical scheme and accompanying drawing.
The first step: size parts to be assembled 4, right micro part 8, left micro part 10 are placed in to part material loading seat 13;
Second step: mobile mechanical arm makes clamp be positioned at tool stand top, controls clamp folding, makes its gripping absorption syringe needle.Control manipulator motion, the clamp of the absorption of gripping syringe needle is moved to part material loading seat 13, open vacuum generating device, absorption is positioned at the right micro part 8 on part material loading seat 13, and is moved to and be mounted with base 5 tops;
The 3rd step: right micro part 8 is placed in to right diametric hole 15 tops that are mounted with on base 5, under the detection of vision system, make itself and the edge that is mounted with base 5 keep certain depth of parallelism, open vacuum generating device, make to be mounted with the 15 one-tenth vacuum states of right diametric hole on base 5, adsorb and fix right micro part 8.
The 4th step: repeat second step, left micro part 10 is moved to and is mounted with base 5 tops;
The 5th step: left micro part 10 is placed in to left diametric hole 14 tops that are mounted with on base 5, under the detection of vision system, makes itself and the edge that is mounted with base 5 and right micro part 8 keep certain depth of parallelism.Open vacuum generating device, the left diametric hole 14 that makes to be mounted with on base 5 forms vacuum state, adsorbs and fixes left micro part 10;
The 6th step: adhesive is put respectively on right micro part 8 and left micro part 10;
The 7th step: mobile clamp is replaced absorption syringe needle, and pick up and pick up Attraction block 9; Control manipulator motion, the clamp that gripping is picked up to Attraction block 9 moves to part material loading seat 13, opens vacuum generating device, and absorption is positioned at the size parts 4 on part material loading seat 13, and is moved to and be mounted with base 5 tops;
The 8th step: size parts 4 is placed in and is mounted with base 5 tops, utilize vision system to determine the position and attitude of size parts 4; Control manipulator motion, it is contacted with left micro part 10 gently with the right micro part 8 that scribbles adhesive, utilize Micro-force sensor control contact force size, prevent that part from producing deformation;
The 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 pick up Attraction block 9, size parts 4 and the pedestal that keep fixture, pick up like this Attraction block 9 and can play position to micro part and the maintenance effect of attitude, be pressed on one with pedestal.After high-temperature process, adhesive generation effect, takes off and picks up Attraction block, to guarantee that assembly precision is not destroyed, thereby has realized the precision assembling of micro part and pedestal.
