Embodiment
With reference now to accompanying drawing, wherein identical numeral refers to identical element in whole several view, Fig. 1 and Fig. 2 illustrates ultrasonic inspection system 10.Ultrasonic inspection system 10 can be constructed to conical array 15.Conical array 15 comprises the back 20 with basic coniform shape.Ultrasonic inspection system 10 also comprises multiple transducer 25.Transducer 25 can be located around the back 20 of conical array 15.Transducer 25 is generally manually located and is bonded to back 20.The use of conical array 15 makes sound wave be propagated with required incident angle by transducer 25.Ultrasonic inspection system 10 can be inserted in pipe 30, for the wall to mode testing tube 30 similar as mentioned above.
Fig. 3 illustrates the example of ultrasonic inspection system 100 as described herein.Ultrasonic inspection system 100 can be set to conical array 110.Conical array 110 can comprise the back 120 with basic coniform shape.Conical back 120 can be made up of the material of any type of not interfering with the ultrasound wave produced herein.Ultrasonic inspection system 100 and conical back 120 can have any size.Miscellaneous part and other structures can be adopted at this.
Ultrasonic inspection system 100 can also comprise ultrasound transducer assembly 130.Ultrasound transducer assembly 130 can comprise the P.e.c. matrix 140 for being positioned on conical back 120.Matrix 140 can be film, flexibility, the printed circuit materials of any type, such as, for example unrestricted, polyimide film, electro-deposition copper foil and similar material.Also nonmetallic materials can be adopted.Transducer 150 can be attached to P.e.c. matrix 140.Transducer 150 can be the piezoelectric element of any type converting electric energy to sound wave.In addition, multiple independent transducer 150 can be applied to P.e.c. matrix 140.Miscellaneous part and other configurations can be adopted at this.
In order to adapt to the shape of conical array 110, the transducer 150 of ultrasound transducer assembly 130 can have the multiple spaced cuts 160 formed on it.Spaced cuts 160 can manually be formed or to comprise cut, the automated manner of die-cut and other technologies formed.Once complete spaced cuts 160, multiple independently element of transducer 170 remains with gap 180 betwixt.Spaced cuts 160 can extend beyond transducer 150 and extend in P.e.c. matrix 140.The independently element of transducer 170 therebetween with gap 180 can be expanded as illustrated in fig. 5.Any amount of spaced cuts 160 and independently element of transducer 170 can be adopted at this.Independently element of transducer 170 and gap therebetween 180 can have any size, shape or structure, and can change according to the size at conical back 120, shape and structure.Spaced cuts 160 also can be applied thereon the P.e.c. matrix 140 with multiple transducer 150.Miscellaneous part and other configurations can be adopted.
Each independently in element of transducer 170 all can be communicated with conductor 190.Conductor 190 then can be communicated with connector/binding post 200 and like.Conductor 190 and connector/binding post can be conventional design.As shown in the figure, in figure 6, then P.e.c. matrix 140 can be attached to the back 120 of conical array 110 together with the independently element of transducer 170 of ultrasound transducer assembly 130.Independently element of transducer 170 can be folded into the outside (or inner) at conical back 120 with the conical structure of forming element.Therefore ultrasound transducer assembly 130 can adapt to whole peripheries of conical array 110.Connector/binding post 200 can be arranged to be communicated with control module in a conventional manner.
Fig. 7 illustrates the process flow diagram of the high standard step that can be used to form ultrasound transducer means 100.In first step 210, transducer 150 can be attached to P.e.c. matrix 140.In second step 220, spaced cuts 160 can be applied to transducer 150 and the form that can be arranged to have gap 180 therebetween forms independently element of transducer 170.Alternately, in alternative first step 230, multiple independent transducer 150 can be attached to P.e.c. matrix 140.In alternative second step 240, spaced cuts 160 can be applied to P.e.c. matrix 140 and the form that can be arranged to have gap 180 therebetween forms independently element of transducer 170.In arbitrary example, in third step 250, conductor 190 could be attached to independently element of transducer 170.In the 4th step 260, P.e.c. matrix 140 can be attached to back 120.In the 5th step 270, independently can to cross back 120 folding to complete ultrasonic inspection system 100 for element of transducer 170.These steps can perform with different orders.Other step can be adopted at this.
Therefore, ultrasonic inspection system 100 provides the conical array 110 with ultrasound transducer assembly 130, need not locate individually and bond or the multiple transducer 150 of attaching simultaneously.More suitably, spaced cuts 160 produces the independently element of transducer 170 with gap 180 therebetween, so that by adapting to the shape of conical array 110 around the folding independently element of transducer 170 in conical back 120.Similarly, the spaced cuts 160 extended in P.e.c. matrix 140 also can adapt to multiple independent transducer 150.Therefore, compared with the known ultrasonic apparatus used together with general and conical array, ultrasonic inspection system 100 can be assembled into phased array with less labour within less time.
Should be appreciated that and only relate to some embodiment of the present invention above.When not departing from as by the general spirit of the present invention of following claim and equivalency thereof and scope, those skilled in the art can make multiple change and modification at this.
