Described several probes adopt the mode of integrated encapsulation.
Described each probe is for being divided into some wafer, and every of being partitioned into of described wafer is a son probe.
The signal wire that described son probe links to each other with master controller is a polycore cable.
Described master controller is a multiplexer.
The utility model compared with prior art has the following advantages:
Only adopt single probe, can single pass accomplish all standing of surveyed area, can significantly improve speed that scanning detects or the technical sophistication degree that reduces double probe.
Description of drawings
Fig. 1 does not have the son probe arrangement of the many linear transducer array scanning in gap ultrasonic test equipment for the utility model is a kind of;
Fig. 2 is divided into two overlapping principle schematic of the son adjacent acoustic beam with it of probe for the probe of the utility model.
Embodiment
Below in conjunction with accompanying drawing,, the utility model is done further elaboration through specifying a preferable specific embodiment.
The many linear transducer array scanning in a kind of no gap ultrasonic test equipment comprises: the probe of master controller and several single-row arrangements.Wherein, each probe comprises the son probe of several single-row arrangements, the single-row arrangement of all son probes that several probes comprise; Master controller links to each other through signal wire with each height probe respectively.In the present embodiment, several probes adopt the mode of integrated encapsulation, and each probe is for being divided into some wafer, and each sheet that wafer is cut apart constitutes a son probe; The signal wire that the son probe links to each other with master controller is a shielded multiconductor cable, has improved the reliability of signal wire; Master controller is selected multiplexer for use, can make the passage that connects each son probe have switching function.
As depicted in figs. 1 and 2; In the present embodiment, be example to need overlapping 1/2 of the single beam angle that is covered as of acoustic beam, this defect-detecting equipment comprises two probes: probe 1, probe 2; Each is popped one's head in and is the wafer that is divided into two; Promptly comprise two son probes, be respectively: son probe 11,12 and son probe 21,22, its neutron probe 12 and the 21 adjacent arrangements of son probe.Each son probe all constitutes a passage, through multiplexer, can make scanning have certain phase difference through exciting different son probe combinations successively, realizes phased array scanning, and the consistance of array probe is well ensured.
As shown in Figure 2, when exciton probe 11 and son probe 12, form the detection acoustic beam that the dotted line that has a down dip is represented left; When exciton probe the 12 and the 3rd son probe 21, the formation detection acoustic beam that dotted line is represented that has a down dip to the right then; When exciton probe 21 and son probe 22, then form the detection acoustic beam that the dotted line that has a down dip is represented again left.Because probe 1 and pop one's head in and have the gap between 2; This gap is generally 0.1mm; And can find out significantly that from Fig. 2 adjacent two acoustic beam overlapping areas are near 1/2 of single detection beam width; Satisfy overlapping 1/2 the requirement that is covered as single beam angle of present acoustic beam fully, can be owing to the gap of detecting between the acoustic beam forms omission.For except that the son probe 11 and son probe 22 of linear transducer array both sides; Son probe 21 and son probe 12 all with adjacent son probe combination respectively; Accomplish twice emitting/reception, overlay area, the obtainable no gap of single pass is the linear transducer array width that all son probes are formed, and the surveyed area width decision that the total number of son probe need cover based on single pass; Width is big more, and the number of son probe is corresponding many more.
In sum, the many linear transducer arrays in a kind of no gap of the utility model scanning ultrasonic test equipment only adopts single probe, can single pass accomplishes all standing of surveyed area, can significantly improve speed that scanning detects or the technical sophistication degree that reduces double probe.
Although the content of the utility model has been done detailed introduction through above-mentioned preferred embodiment, will be appreciated that above-mentioned description should not be considered to the restriction to the utility model.After those skilled in the art have read foregoing, for the multiple modification of the utility model with to substitute all will be conspicuous.Therefore, the protection domain of the utility model should be limited appended claim.
