Description

TECHNICAL FIELD

[0001] The present application relates to a transducer, more particularly to a high-power ultrasonic transducer. BACKGROUND

[0002] The working principle of the ultrasonic transducer is that when an external electric field is converted into an alternating electric field, the piezoelectric sheet will generate an alternating deformation with the same frequency as the alternating electric field, so that the piezoelectric sheet radiates sound waves outward on both sides. When the frequency of the external electric field is the same as the natural frequency of the piezoelectric sheet, the piezoelectric sheet vibrates most and the sound radiation is also the strongest. The conventional ultrasonic transducer only works through a single piezoelectric ceramic, and the power is limited by the power of the piezoelectric ceramic itself, and a large-power ultrasonic transducer cannot be formed by superposition. SUMMARY

[0023] like Figures 7-8 As shown, this example can achieve the effect of forming a high-power ultrasonic transducer.

[0024] Since the high-power ultrasonic transducer includes a piezoelectric ceramic 306, and electrode plates 307 are bonded to both the upper and lower sides of the piezoelectric ceramic 306, and conductive posts 308 are provided on both electrode plates 307, the piezoelectric ceramic 306 vibrates and emits ultrasonic waves by passing electricity through the two conductive posts 308 to the two electrode plates 307. Multiple piezoelectric ceramics 306 are provided, and by stacking multiple piezoelectric ceramics 306, ultrasonic waves can be emitted simultaneously by multiple piezoelectric ceramics 306 to form a high-power ultrasonic transducer.

[0025] As shown in Figures 7-8 , this example can achieve the effect of emitting ultrasonic waves through the plug-in block 301.

[0026] Since the high-power ultrasonic transducer also includes the plug-in block 301, parallel sheets 309 are welded on both the upper and lower ends of the front side of the plug-in block 301, the piezoelectric ceramic 306 and the two electrode plates 307 are bonded between the two parallel sheets 309, and the two conductive columns 308 pass through the two parallel sheets 309, respectively. The vibration emitted by the piezoelectric ceramic 306 is transmitted to the two parallel sheets 309, and then transmitted to the plug-in block 301 through the two parallel sheets 309, and the ultrasonic waves are emitted through the plug-in block 301.

[0027] As shown in Figures 5-6 , this example can achieve the effect of superimposing and transmitting ultrasonic waves emitted by multiple plug-in blocks 301 to the flat plate 101.

[0028] Since the high-power ultrasonic transducer also includes the flat plate 101, the lower side of the flat plate 101 is connected with the slot rod 108 through a screw, and the slot rod 108 and the flat plate 101 form a slot therebetween. The lower side of the plug-in block 301 is provided with a slope 302, the plug-in block 301 is inserted into the slot, and the slope 302 is in contact with the slot rod 108. By inserting the slope 302 on the plug-in block 301 into the slot, the top surface of the plug-in block 301 is fully in contact with the flat plate 101. Multiple plug-in blocks 301 can be inserted into the slot, and then the ultrasonic waves emitted by the multiple plug-in blocks 301 are superimposed and transmitted to the flat plate 101.

[0029] As shown in Figures 5-8 , this example can achieve the effect of preventing the plug-in block 301 from moving left and right relative to the flat plate 101.

[0030] Since the lower side of the flat plate 101 is provided with multiple limiting edges 107 from left to right, the plug-in block 301 is inserted between two of the limiting edges 107, and the plug-in block 301 is prevented from moving left and right relative to the flat plate 101 by the limitation of the multiple limiting edges 107.

[0031] As shown in Figures 7-8 , this example can achieve the effect of pressing the plug-in block 301 towards the slot rod 108 and the slot.

[0032] Since the front side of the plug-in block 301 is welded with a guide rod 303 at the lower part, the guide rod 303 is welded with a stopper 305 at the front end, a sliding sheet 304 is slidingly connected to the guide rod 303, and a compression spring is sleeved on the guide rod 303. The compression spring is located between the plug-in block 301 and the sliding sheet 304. Pressing the sliding sheet 304 to the right drives the sliding sheet 304 to move backward relative to the guide rod 303, and then the force of the compression spring acting on the plug-in block 301 makes the plug-in block 301 press towards the slot rod 108 and the slot.

[0033] As shown in Figures 5-8As shown in the figure, this example can achieve the effect of making the ultrasonic waves emitted by the plurality of plug-in blocks 301 pass through the flat plate 101 and be superimposed and emitted on the flat plate 101.

[0034] Since the left and right ends of the lower side of the flat plate 101 are both welded with bottom columns 203, the door-shaped pressing piece 201 is slidingly connected to the two bottom columns 203 in the front-back direction, the door-shaped pressing piece 201 is pressed on the front side of the sliding sheet 304, and the fastening screw 202 is threadedly connected to each bottom column 203 202, the fastening screw 202 is pressed on the door-shaped pressing piece 201, and when the door-shaped pressing piece 201 moves backward on the two bottom columns 203, the door-shaped pressing piece 201 drives the door-shaped pressing piece 201 to press the sliding sheet 304 on the front side of the plurality of plug-in blocks 301, so that the plurality of plug-in blocks 301 are simultaneously pressed into the plug-in slots, so that the plurality of plug-in blocks 301 are simultaneously attached to the flat plate 101, so that the ultrasonic waves emitted by the plurality of plug-in blocks 301 pass through the flat plate 101 and are superimposed and emitted on the flat plate 101.

[0035] As Figures 5-6 shown in the figure, this example can achieve the effect of transmitting the ultrasonic waves superimposed and emitted on the flat plate 101 to the ultrasonic wave receiving object.

[0036] Since the left and right sides of the flat plate 101 are both welded with connecting sheets 104, and a screw is inserted into each connecting sheet 104, the two connecting sheets 104 can be connected to the ultrasonic wave receiving object through the screws on the two connecting sheets 104, and the ultrasonic waves superimposed and emitted on the flat plate 101 are transmitted to the ultrasonic wave receiving object.

[0037] As Figures 5-6 shown in the figure, this example can achieve the effect of adjusting the contact position of the object to release ultrasonic waves.

[0038] Since the upper side of the flat plate 101 is provided with a left-right direction track 103, and a plurality of cylinders 102 are slidingly connected to the track 103, when in contact with the ultrasonic wave receiving object, the upper side of the plurality of cylinders 102 is in contact with the object, the ultrasonic waves are transmitted through the plurality of cylinders 102, and the plurality of cylinders 102 can be slidingly adjusted in the left-right position on the track 103, thereby adjusting the contact position of the object to release ultrasonic waves.

[0039] As Figures 1-10 shown in the figure, this example can achieve the effect of adjusting the contact area of the cylinder 102 with the ultrasonic wave receiving object.

[0040] Since each cylinder 102 is slidably connected with a collar 402, and the front of each collar 402 is slidably connected to the lifting frame 401 in the left and right directions, and each side seat 105 is welded to the left and right sides of the plate 101, and each side seat 105 is threadedly connected with a pressure screw 106, the lifting frame 401 is vertically slidably connected to the two side seats 105, and the upper parts of the two pressure screws 106 are pressed against the lifting frame 401. The multiple collars 402 can slide vertically on the multiple cylinders 102 respectively, thereby adjusting the contact area between the cylinder 102 and the object receiving the ultrasonic wave. When the lifting frame 401 slides vertically on the two side seats 105, it can drive the multiple collars 402 to rise and fall simultaneously, thereby increasing the upper area of ​​the multiple cylinders 102 simultaneously. The contact area between the cylinder 102 and the object is different, and the ultrasonic wave release effect is different. When the cylinder 102 moves left and right along the track 103, the corresponding collar 402 can also move left and right on the lifting frame 401.

[0041] like Figures 1-10 As shown, this example can further increase the contact area between the cylinder 102 and the object.

[0042] Since extension rods 408 are welded to both the left and right ends of the rear side of the lifting frame 401, and square columns 407 are welded to both the left and right ends of the crossbar 405, the two square columns 407 are vertically slidably connected to the rear of the two extension rods 408, and each extension rod 408 is threaded with a fastening screw. 406, two fastening screws 406 is pressed on two square pillars 407 respectively. Each collar 402 has a hinged rotating block 403 at the rear. Each rotating block 403 is provided with a sliding hole 404 in the left and right direction. The crossbar 405 passes through multiple sliding holes 404. When the two square pillars 407 slide vertically on the two extended rods 408 respectively, they can drive the crossbar 405 to rise and fall, thereby driving multiple rotating blocks 403 to rotate relative to multiple collars 402 respectively. When multiple rotating blocks 403 rotate to be on the same plane as the upper side of multiple collars 402, the contact area between the cylinder 102 and the object can be further increased.
