Embodiment
As shown in Figures 1 to 4, be a kind of high accuracy small size reinforcement applying method of the present invention, in turn include the following steps:
A. prepare a reinforcement raw material plate and a support plate; Reinforcement raw material plate comprises diffusion barrier 13, reinforcement glue-line 12 and the strengthening course 11 stacking gradually; Support plate comprises support plate glue-line 22 and the carrier plate material film 21 stacking gradually; Reinforcement raw material plate and support plate laminating are to stick on support plate glue-line 22 by strengthening course 11, and reinforcement raw material plate and support plate form reinforcing block.
The material of carrier plate material film 21 is polyimides (PI), polyester resin (PET), and liquid crystal polymer (LCP), PEN (PEN), polytetrafluoroethylene (PTFE) is any one in film.
B. the outer surface of diffusion barrier 13 is the top of reinforcement raw material plate, and strengthening course 11 is the bottom of reinforcement raw material plate with the one side that support plate glue-line 22 is pasted.
On reinforcing block, delimit the zone of action (profile of the zone of action is on diffusion barrier 13), beyond the zone of action for removing region; On the reinforcing block in region, offer registration holes 4 removing; Profile along the zone of action is cut to the bottom of reinforcement raw material plate from the top of reinforcement raw material plate.By laser equipment or blanking equipment, reinforcing block is carried out to perforate and cutting.
C. the reinforcement raw material plate that removes region is removed, the diffusion barrier 13 of reinforcement raw material plate on the zone of action is removed.Shown in Fig. 4, A is the zone of action, and B is for removing region.
In the d of Fig. 2, e step and in the f of Fig. 3, g step, A represents CCD para-forms, B representative location borehole jack nail mode.
D. by location borehole jack nail mode or CCD contraposition, reinforcing block is aimed at product 3, and the reinforcement glue-line of reinforcement raw material plate on the zone of action 12 and product 3 are affixed.
E. reinforcement glue-line 12 thermoplastics to reinforcement raw material plate on the zone of action, and reinforcing block and product 3 are pressurizeed.
F. adopt with the mechanical arm of vacuum cups and peel off support plate, or peel manually is from support plate.
G. remaining reinforcement raw material plate and product 3 are pressurizeed, and by baking-curing reinforcement glue-line 12, reinforcement has been fitted.
The mode of described location borehole jack nail mode indication is: on product 3, corresponding registration holes 4 arranges perforate, and registration holes 4 is alignd with perforate, then nail is inserted to registration holes 4 and perforate, realizes product 3 and reinforcing block location.Adopt location borehole jack nail mode to aim at product, need to use special fixture, after having aimed at, product is shifted out from special fixture.
Wherein:
Strengthening course 11 materials are polyimides (PI), polyester resin (PET), liquid crystal polymer (LCP), PEN (PEN), polytetrafluoroethylene (PTFE) is film, FR-1, FR-2, FR-4, pottery, any one in steel disc.
Strengthening course 11 thickness are 0.01mm-0.3mm; Reinforcement bondline thickness is 0.01mm-0.2mm.
The thickness of carrier plate material film 21 is 0.025-0.2mm, and the thickness of support plate glue-line 22 is 0.01-0.1mm.
The advantage of reinforcement applying method of the present invention:
Reinforcement raw material plate and support plate laminating, stick reinforcement to product 3 subsequently again; Allow in reinforcement laminating process, all very convenient to picking and placeing of reinforcing block, and more easily locate and aim at, and then accelerate the speed of whole reinforcement laminating.
Adopt laser cutting, cut quality is good, cutting efficiency is high; During cutting, cutting torch and workpiece are contactless, so can not produce wearing and tearing to reinforcing block, further, the joint-cutting of laser cutting is narrow, are out of shape littlely, generally speaking protect the integrality of whole reinforcing block and protect its performance.The cutting of employing stamping-out, efficiency is high, accurate positioning.
By location borehole jack nail mode or CCD contraposition, realized and being aimed at, aligning accuracy is high and quick, meets high-precision requirement.
Laminating, then preheating pressurization, finally dries laminating, guarantees that the laminating of reinforcement and product 3 is tight, and both are not easily separated.
Reinforcement raw material plate and support plate fitted in advance and directly cut out the size needing, then by location borehole jack nail mode or CCD contraposition, aim at laminating with product 3, finally by preheating and twice pressurization, allowing reinforcement and product 3 fit tightly.Whole flow process has reduced the difficulty of laminating small size reinforcement, improves laminating efficiency, and guarantees the positional precision of reinforcement.
The thickness that strengthening course 11 arranges guarantees reinforcing effect optimization, and reinforcement glue-line 12 thickness guarantee that the combination between strengthening course 11 and product 3 is stable and can not cause adverse effect.
In the present invention, the stickiness of 22 pairs of strengthening courses of support plate glue-line is lower than the stickiness on 12 pairs of product 3 surfaces of reinforcement glue-line, and when peeling off carrier plate material, on product and on strengthening course, can not have cull.In d, e step, in objective circumstances, likely there will be support plate glue-line 22 also to stick on product 3, so the stickiness of 22 pairs of products 3 of support plate glue-line is also lower than the stickiness on 12 pairs of product 3 surfaces of reinforcement glue-line.
Support plate and reinforcement raw material plate do not need contraposition, and positional precision is realized by blanking equipment or laser equipment.
Support plate has played framework effect in the method, and with isolated, small size reinforcement raw material plate becomes as a whole in technique, has avoided the highly difficult processing to small size reinforcement raw material plate.The thickness that carrier plate material film 21 arranges, guarantees it as the steadiness of a framework and can not form and hinder to reinforcement raw material plate, the thickness assurance of support plate glue-line 22 and the stable bond between reinforcement raw material plate.
The present invention is not limited to above-mentioned execution mode, if various changes of the present invention or modification are not departed to the spirit and scope of the present invention, if within these changes and modification belong to claim of the present invention and equivalent technologies scope, the present invention is also intended to comprise these changes and change.
