Abstract
Disclosed is an ultrasonic line structure for welding a plastic piece, which comprises a preset ultrasonic line, and is characterized in that the section of the preset ultrasonic line is the semi-arc shape. The section of the ultrasonic line of the utility model is the semi-arc shape improved from the isosceles triangle shape of the prior art, the semi-arc ultrasonic line has the same area of section with the isosceles triangle shape one, and has lower height than the isosceles triangle shape ultrasonic line, and when the energy of ultrasonic is low, the ultrasonic cold solder joint will not take place easily, and the semi-arc sectional ultrasonic line can evenly distribute the energy of ultrasonic at all parts in the welding area and maximally utilize the pressure produced and energy released by the ultrasonic welding machine, therefore, the utility model can save energy and fully melt the ultrasonic line, thus ensuring the firm and artistic connection of all parts in the welding area in a narrow space of the plastic piece; meanwhile, the welding space can be saved under the condition of sufficient packing materials, so the utility model is highly applied to the narrow welding space, and can also save the space for ultrasonic line design, thereby increasing the effective design space utilization rate per unit area.
Description
Technical field
The utility model relates to ultrasound lines, especially relates to a kind of ultrasound lines structure of welding plastic parts.
Background technology
Ultra-sonic welded is existing frivolous slimline plastic product, comprises the main welding method of mobile phone machine plastic part.Hyperacoustic welding pressure, preheat temperature, weld interval, and hyperacoustic power and amplitude directly influence the effect of welding.Plastic parts must preset the welding position of bone as lines, i.e. ultrasound lines by ultra-sonic welded on plastic parts.Ultrasonic welding machine provides the ultrasonic energy that comprises heat, pressure to make the ultrasound lines fusing, just the part that two plastic parts overlap mutually can be welded together.The design principle of ultrasound lines is to increase intensity, minimizing flash, minimizing weld interval and hyperacoustic amplitude of solder side.But, conventional ultrasound lines cross sectional shape is an isosceles triangle, in the welding process when ultrasound lines applies the ultrasonic energy that comprises heat, pressure, because the area on isosceles triangle top is less, the area that bears the ultrasonic energy that comprises heat, pressure is just less relatively, makes the ultrasonic energy of ultrasonic welding machine fully not to be utilized.Fill full weld and connect the zone, will increase leg-of-mutton height, also will increase hyperacoustic amplitude, promptly need to increase hyperacoustic energy, could guarantee welding quality; Owing to increased leg-of-mutton height, hyperacoustic amplitude changes again in the welding process, and it is excessive ultrasonic energy very easily to occur latter stage in welding, makes the welding region distortion or burns plastic parts; And in narrow and small welding space, increase leg-of-mutton height and especially be restricted.
Summary of the invention
Technical problem to be solved in the utility model is the defective that remedies above-mentioned prior art, ultrasound lines structure based on small space welding plastic parts, can only set about from the cross sectional shape that improves ultrasound lines, reduce the height of ultrasound lines as far as possible, make scolder can fully fill welding region, reaching firm welding and postwelding zone in small space does not have the effect of flash, proposes a kind of ultrasound lines structure of welding plastic parts.Both satisfied the welding demand of frivolous slimline plastic product, again energy savings as much as possible.
Technical problem of the present utility model is achieved by the following technical programs:
The ultrasound lines structure of this welding plastic parts comprises the ultrasound lines that presets.
The characteristics of the ultrasound lines structure of this welding plastic parts are:
The cross sectional shape of the described ultrasound lines that presets is a semicircular arc.
Technical problem of the present utility model is achieved by following further technical scheme:
Described semicircular arc is monosymmetric semicircular arc.
Described semicircular arc comprises semisinusoidal waveform, semicircle.
The described ultrasound lines that presets is the ultrasound lines that injection moulding is preset on described welding plastic parts.
The described ultrasound lines that presets is by the special-purpose injection mold ultrasound lines that injection moulding is preset on described welding plastic parts.
The beneficial effect that the utility model is compared with the prior art is:
The ultrasound lines cross sectional shape that the utility model presets is that the isosceles triangle by prior art is improved to semicircular arc, the semicircular arc ultrasound lines identical with the isosceles triangle sectional area, the height of its aspect ratio isosceles triangle ultrasound lines is low, when ultrasonic energy is low, be not prone to ultrasonic rosin joint, and the ultrasound lines in semicircular arc cross section can make the ultrasonic energy uniform distribution at each position of welding region, the pressure that utilizes ultrasonic welding machine to greatest extent and produced and the heat of release, make the ultrasound lines welding abundant, guarantee that each position of welding region all firmly connects in the plastic parts small space, attractive in appearance; Simultaneously, under the enough prerequisite of inserts amount, can save the welding space, be highly suitable for narrow and small welding space; Make full use of the energy of ultrasonic welding machine, energy savings can also be saved the space of ultrasound lines design, improves the effective rate of utilization of unit are design space.

The specific embodiment
A kind of ultrasound lines structure of frivolous slimline mobile phone shell plastic parts
In order to make firm welding reliable, there are many to be interrupted the ultrasound lines 1 that distributes in the design of shell plastic parts, its distribution situation is as shown in Figure 1.The cross sectional shape of ultrasound lines 1 is the semisinusoidal waveform, is common monosymmetric semicircular arc.According to the welding needs of welding plastic parts 2,, preset by the injection moulding on welding plastic parts 2 of special-purpose injection mold with the diverse location of ultrasound lines 1 design at welding plastic parts 2.This ultrasound lines structure had both satisfied the ultra-sonic welded demand of small space plastic parts 2,3, had saved the energy again as much as possible.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention/utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
