For solving on the premise of the bond strength ensureing ultrasonic sealing, it is impossible to relatively thin at sidewall thickness
The problem arranging barricade on upper casing or lower casing, the utility model proposes a kind of ultra-sonic welded anti-overflow cementing
Structure, as depicted in figs. 1 and 2, including speaker module casing, described speaker module casing includes
Upper casing 1 and lower casing 2, wherein, described upper casing 1 and/or described lower casing 2 are provided with ultrasound lines 4 and storage
Glue groove 5, described storage glue groove 5 relative to described ultrasound lines 4 adjacent to described upper casing 1 sidewall edge and/
Or the sidewall edge of described lower casing 2, above-mentioned ultrasound lines 4 and storage glue groove 5 both of which can be located at upper casing 1
Or on lower casing 2 or ultrasound lines 4 is located on upper casing 1 storage glue groove 5 and is located on lower casing 2 or super
Sound ray 4 be located on lower casing 2 storage glue groove 5 be located on upper casing 1 or on upper casing 1 and lower casing 2 simultaneously
Being provided with ultrasound lines 4 and storage glue groove 5, those skilled in the art can select the most flexibly.
During ultrasonic sealing, first lower casing 2 is fixed on ultrasonic base, and upper casing 1 correspondence is put
Putting on lower casing 2, now ultrasound lines 4 is positioned at and is pressed on upper casing 1 and/or lower casing 2, then by ultrasonic head
It is depressed into upper casing 1 surface ultrasonic energy to be transferred to upper casing 1 and the adhesive surface of lower casing 2, because of ultrasonic energy
The localized hyperthermia that amount causes makes upper casing 1 and lower casing 2 that partial melting can occur at adhesive surface, melted
After liquid plastic upper casing 1 and lower casing 5 are bonded together, unnecessary fused solution plastics enter storage
In glue groove 5, thus prevent ultrasonic excessive glue problem.
Ultra-sonic welded adhesive-spill-preventing structure of the present utility model is by arranging on upper casing 1 and/or lower casing 2
The storage glue groove 5 of the sidewall edge of neighbouring upper casing 1 and/or lower casing 2 is many during storing ultrasonic sealing
Remaining fused solution plastics, owing to storage glue groove 5 the most additionally takies adhesive surface, therefore can be super in guarantee
On the premise of the bond strength of acoustic seal, solve well cannot the relatively thin upper casing of sidewall thickness or under
The problem that barricade is set on shell.Additionally, enter the thickness after the fused solution plastics solidification of storage glue groove 5
Relatively big, it is thus advantageous to improve upper casing 1 and lower casing 2 is positioned at the adhesion at storage glue groove 5, improve super
The effect of acoustic seal.
In order to arrange ultrasound lines 4 and storage glue groove 5, described ultrasound lines 4 and described storage glue groove more easily
5 are respectively positioned on described upper casing 1 or described lower casing 2.
Further, owing to lower casing 2 typically requires bigger intensity, thus should avoid at lower casing 2
On the structures such as extra groove are set, therefore, described ultrasound lines 4 and described storage glue groove 5 are respectively positioned on described
On upper casing 1.
Overflow from the edge of upper casing 1 and lower casing 2 to be better protected from the liquid plastic after melting, institute
State spacing L between storage glue groove 5 and the sidewall edge of described upper casing 1 with 0.5mm-0.8mm1。
In order to preferably store unnecessary fused solution plastics, described ultrasound lines 4 and described storage glue groove 5
Abut against together, above-mentioned adjacent refer to that ultrasound lines 4 is directly linked together with storing up glue groove 5, both it
Between there is no distance.
In order to prevent unnecessary fused solution plastics from flowing in the inner chamber 3 of speaker module casing, described
There is between the inner chamber 3 of ultrasound lines 4 and described speaker module casing spacing L of 0.5mm-0.8mm2。
In a preferred embodiment of the present utility model, as shown in Figure 2, described ultrasound lines 4 edge
The section the direction that ultrasonic energy is propagated is isosceles triangle, and described storage glue groove 5 is along ultrasonic energy
The section in the direction propagated is rectangle, and this set is conducive to being better protected from the liquid plastic after melting
Overflow from the edge of upper casing 1 and lower casing 2, and improve the bond strength of ultrasonic sealing.
In order to, under conditions of the bond strength ensureing ultrasonic sealing, preventing storing up glue groove 5 affects too much
To upper casing 1 and/or the self-strength of lower casing 2, the volume of described storage glue groove 5 is described ultrasound lines 4
The 1/2 to 2/3 of volume.
Further, described storage glue groove 5 along the height H of the ultrasonic energy direction of propagation is
0.6mm-1.0mm。
Although specific embodiments more of the present utility model being described in detail by example,
But it should be appreciated by those skilled in the art, above example is merely to illustrate rather than be
Restriction scope of the present utility model.It should be appreciated by those skilled in the art, can be without departing from this reality
In the case of novel scope and spirit, above example is modified.Model of the present utility model
Enclose and be defined by the following claims.
