Abstract
The present invention's a kind of ultrasonic wave demoulding equipment and method, at first, the transducer of this equipment is fixed on template or the mould emptier; Utilize the cyclelog that is connected with supersonic generator that the unlatching parameter is set thereafter; Open supersonic generator, supersonic generator is started working energy is spread out of transducer, transducer is passed to template with ultrasonic wave and mechanical oscillation, template begins vibration and simultaneously energy is passed to printed article, impel printed article to produce cavitation effect at the small opening place of template ultrasonic wave, thereby the reduction adhesive capacity, the mechanical oscillation of transducer simultaneously also have good facilitation to the demoulding.
Description
[technical field]
The present invention relates to improve the new technology of the release problems in the mould printing, relate in particular to by hyperacoustic mechanical oscillation and cavitation effect and make printed article break away from the method and apparatus of die body fully.
[background technology]
Existing release method is by the speed that changes the demoulding printed article slowly to be spun off from template, because the viscous effect of printed article, cause printed article to be bonded in the edge and the corner of template, cause the level that the amount that is printed thing is lower than to be needed, particularly for narrow small opening, this phenomenon is more serious.
In order to address this problem, prior art has adopted the acceleration demoulding, ways such as mechanical oscillation, its effect still can not satisfy the demoulding requirement of tiny small opening, particularly for the paste solder printing in the electronics assembly industry, because the amount of tin cream directly influences the intensity of welding, therefore improve press quality and speed, directly influence the quality of product and the efficient of factory.
[summary of the invention]
The objective of the invention is to utilize cavitation and the mechanical oscillation of ultrasonic wave in fluid.Not only solved the problem of the demoulding, the time of the demoulding is shortened greatly, quality and efficient are got a promotion significantly.
The invention provides a kind of ultrasonic wave demoulding equipment, it comprises supersonic generator, a supply power, a cyclelog, a transducer, wherein, supply power is connected with supersonic generator to be used for its power supply, and cyclelog is connected the relevant parameter of controlling described supersonic generator with supersonic generator; And the transducer that is connected with supersonic generator; described transducer is fixed on template or the mould emptier; the ultrasonic wave that transducer produces is transferred on the printed article by template; cavitation effect takes place in the small opening border of template; reduce adhesive capacity, the mechanical oscillation of transducer simultaneously also have good facilitation to the demoulding.
Above-mentioned transducer also comprises a vacuum generator, is connected with it, and vacuum is attached to transducer on the template closely.
The present invention also provides a kind of ultrasonic wave release method, comprises step: step 1, the transducer that is connected with ultrasonic wave are fixed on template or the mould emptier; Step 2 utilizes the cyclelog that is connected with supersonic generator that the unlatching parameter is set; Step 3, open supersonic generator, supersonic generator is started working energy is spread out of transducer, and transducer is passed to template with ultrasonic wave and mechanical oscillation, template begins vibration and simultaneously energy is passed to printed article, impels printed article to produce cavitation effect at the small opening place of template ultrasonic wave.

[specific embodiment]
The invention will be further described by a concrete example below in conjunction with accompanying drawing.
Schematic diagram shown in Figure 1, a kind of ultrasonic wave stripper apparatus 10, it comprises supersonic generator 11, a supply power 12, a cyclelog 13, a transducer 14, wherein, supply power 12 is connected with supersonic generator 11 to be used for its power supply, and cyclelog 13 is connected the relevant parameter of controlling described supersonic generator 11 with supersonic generator 11; And the transducer 14 that is connected with supersonic generator 11, described transducer 14 is fixed on template or the mould emptier 16, and the ultrasonic wave that transducer 14 produces is transferred on the printed article by template 16, and cavitation effect takes place in the small opening border of template 16.
Above-mentioned transducer 14 also comprises a vacuum generator 15, is connected with it, and vacuum is attached to transducer 15 on the template closely.
Its operation principle is: when printing proceeds to ejection phase, supersonic generator 11 is started working energy is spread out of transducer 14, transducer 14 is passed to template 16 with ultrasonic wave and mechanical oscillation, template 16 begins vibration and simultaneously energy is passed to printed article, impels printed article to produce cavitation effect at the small opening place of template 16 ultrasonic wave.The adhesion at interface is destroyed.Should brush thing when mould emptier 16 moves deviates from from mould smoothly.
Fig. 2 is mechanical analysis figure,
Suppose the sticking coefficient n1 of printed article and template
Suppose the sticking coefficient n2 of printed article and support plate
The adhesion Fup of template and printed article
The adhesion Fd of printed article and support plate
The weight of printed article is G.
Fup＝2×(L+D)×T×n1
Fd＝L×D×n2
When Fd+G＞Fup, the demoulding could success.In above formula L T D determined to change the volume of printed article, G also becomes a constant.N is changeable key factor.Printed article all has certain thixotropy, and sticking coefficient will reduce when ultrasonic energy injects, because hyperacoustic decay, reducing of n1 will be greater than n2, and this is the present invention's technical scheme that need solve just.
Fig. 3 is the use-case figure of a kind of ultrasonic wave release method of the present invention.As shown in Figure 3: wherein comprise vacuum generator 15, supersonic generator 11, cyclelog 13, transducer 14 and mould emptier 16.The purpose of vacuum generator 15 is to utilize vacuum to be attached to transducer 14 on the template closely, when printing proceeds to ejection phase, supersonic generator is started working electric weight is spread out of transducer 14, electric energy is converted into ultrasonic wave with transducer 14 and template 16 is passed in mechanical oscillation, template 16 begins vibration and simultaneously energy is passed to tin cream, impels tin cream to produce cavitation effect at the small opening place of template ultrasonic wave.The adhesion at interface is destroyed.Tin cream was deviate from from mould smoothly when mould emptier moved.Cyclelog 13 picks up counting when the demoulding, can set the time of vibration, and ultrasonic wave quits work when the demoulding is finished, and waits for the arrival of next working cycles.
This device also can be integrated in the machine, unifies to control hyperacoustic opening and closing by the software of machine.The mounting means of transducer also can have difference.
The above person only is most preferred embodiment of the present invention, is not to be used to limit the scope of the invention, and all equivalences of doing according to claim of the present invention change or modify, and are all the present invention and contain.
