Description

Technical Field

[0001] The utility model relates to surface size detection, in particular to an automatic surface size detection device for an ultrasonic transducer. Background Art

[0002] An ultrasonic transducer is a device that converts electrical energy into mechanical energy. It is typically made of piezoelectric ceramics or other magnetostrictive materials. Common applications include ultrasonic cleaners, ultrasonic atomizers, and ultrasound probes. Its operating principle is based on the piezoelectric effect of materials, converting electrical signals into mechanical vibrations, thereby achieving energy conversion.

[0003] When the ultrasonic transducer is working, it will generate small-amplitude, high-frequency vibrations. Therefore, a gap must be left between the ultrasonic transducer and the fixed housing so that it will not conflict with the housing during vibration. Since the size of the fixed housing is fixed, the size of the gap is determined by the surface size of the ultrasonic transducer. When the surface size of the ultrasonic transducer is too large, the gap size will be smaller than the amplitude. During vibration, the ultrasonic transducer will continuously collide with the housing, thereby affecting its normal use. In severe cases, it may cause damage to the instrument. Therefore, the surface size of the ultrasonic transducer must be strictly controlled during production. Common surface size detection tools include calipers, optical detectors, etc.

[0004] Generally speaking, ultrasonic transducers are small in size and have a complex shape (cylindrical at the bottom, frustum-shaped in the middle, and cylindrical at the top). Therefore, calipers, rulers, and other tools are generally not used to detect their size. Optical detectors are often used for detection. Once the ultrasonic transducer enters the detection range, the optical detector can quickly detect and analyze its size, and the results are relatively reliable. However, since the detector only has the function of detecting size, it cannot accurately separate qualified products from unqualified products when the dimensional error (unqualified products) is too large. If the two are not distinguished, unqualified products will enter the market, causing losses to customers. Summary of the Invention

[0005] The purpose of the present utility model is to provide an automatic detection device for the surface size of an ultrasonic transducer to solve the problems raised in the above background technology.

[0046] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] See also Figures 1 to 9 , as an embodiment of the present utility model, the surface size automatic detection device of the ultrasonic transducer includes a chassis 1, and a detection table 101, a hopper 16 and a detector 17 installed on the chassis 1;

[0048] The testing platform 101 is provided with a pushing mechanism; the testing platform 101 is provided with a feed trough 102 and a discharge trough 103 which are interconnected, and a turntable 13 is provided between the feed trough 102 and the discharge trough 103;

[0049] The pushing mechanism includes a pushing plate 8; when the pushing mechanism is in operation, the pushing plate 8 will first approach the hopper 16 to drive the sample to slide on the feed trough 102, and after the sample moves to the turntable 13, the pushing plate 8 will move away from the hopper 16 and separate from the sample; at this time, the detector 17 starts to operate; thereafter, the pushing plate 8 approaches the hopper 16 again to drive the sample to slide on the discharge trough 103 until it enters the hopper 16.

[0050] In this embodiment, generally speaking, the size of the ultrasonic transducer is small and its shape is complex (the bottom is cylindrical, the middle is frustum-shaped, and the upper part is cylindrical). Therefore, tools such as calipers and rulers are generally not used to detect its size; the most common method is to use an optical detector for detection; after the ultrasonic transducer enters the detection range, the optical detector can quickly detect and analyze its size, and the result is more reliable.

[0051] When in use, the ultrasonic transducer to be tested is placed vertically in the feed trough 102 and the pushing mechanism is started; the push plate 8 drives the ultrasonic transducer to slide in the feed trough 102 toward the turntable 13. At this time, it is possible to observe whether the ultrasonic transducer remains in a vertical state during the sliding process to determine whether the surface in contact with the feed trough 102 is flat;

[0052] After the ultrasonic transducer reaches the turntable 13 , the push plate 8 will move in the opposite direction away from the hopper 16 to separate from the ultrasonic transducer, so as to prevent the push plate 8 from affecting the detection accuracy when the detector 17 is detecting.

[0053] During the detection process of the detector 17 , the turntable 13 rotates to drive the ultrasonic transducer to rotate, thereby changing the detection angle of the detector 17 to the ultrasonic transducer, so as to further improve the detection accuracy.

[0054] After the detector 17 completes the detection, the push plate 8 will approach the hopper 16 again to drive the ultrasonic transducer that has completed the detection to slide on the discharge chute 103 and finally fall into the hopper 16. Afterwards, the push plate 8 will be away from the hopper 16 to complete the reset.

[0055] The ultrasonic transducer is driven by the pushing mechanism to move into the detection range of the detector 17, and the surface flatness of the ultrasonic transducer can be detected during the movement; when the detector 17 is performing the detection, the pushing mechanism will be separated from the ultrasonic transducer to avoid the pushing mechanism affecting the detection accuracy of the detector 17; after the detection is completed, the pushing mechanism will push the ultrasonic transducer to move into the hopper 16 for the next product to be detected.

[0056] As a further solution of the present utility model, a driving motor 2 is installed on the chassis 1, and a driving wheel 3 is connected to the output end of the driving motor 2. The chassis 1 is rotatably installed with a first driven wheel 4 and a second driven wheel 5 that cooperate with the driving wheel 3. The first driven wheel 4 is connected to a large pulley 401, and the second driven wheel 5 is connected to a large gear 501.

[0057] In this embodiment, the driving wheel 3 , the first driven wheel 4 and the second driven wheel 5 all form a “Maltese cross movement” structure.

[0058] Start the drive motor 2 to drive the driving wheel 3 to rotate; when the driving wheel 3 rotates one circle, it will cooperate with the first driven wheel 4 and the second driven wheel 5 once, thereby driving the first driven wheel 4 and the second driven wheel 5 to rotate a quarter of a circle; thereby driving the large pulley 401 and the large gear 501 to rotate synchronously.

[0059] The rotating large pulley 401 can drive the pushing mechanism to move; the pushing mechanism drives the ultrasonic transducer to move into the detection range of the detector 17 for detection, and after the detection is completed, pushes the ultrasonic transducer to move into the hopper 16.

[0060] As a further solution of the present invention, the pushing mechanism also includes a pushing shaft 6 fixedly and rotatably mounted on the detection platform 101, and a small pulley 601 is connected to the pushing shaft 6, and the small pulley 601 is connected to the large pulley 401 by a belt; a slide groove 602 is provided on the pushing shaft 6; a pushing sleeve 7 slidingly connected to the pushing shaft 6 is rotatably mounted on the push plate 8, and the pushing sleeve 7 is rotatably connected to the detection platform 101; a protrusion 701 slidingly engaged with the slide groove 602 is installed in the pushing sleeve 7; a baffle 702 is installed on the pushing sleeve 7, and a large spring 10 is wrapped around the pushing sleeve 7, and the two ends of the large spring 10 respectively contact the baffle 702 and the detection platform 101; a roller 703 is rotatably mounted on the baffle 702; a fixed sleeve 9 rolling with the roller 703 is installed on the detection platform 101.

[0061] As a further solution of the present invention, the fixing sleeve 9 is provided with a first plane 901 , a first inclined surface 902 , a second inclined surface 903 , a second plane 904 , a third inclined surface 905 , and a fourth inclined surface 906 .

[0062] In this embodiment, the first inclined surface 902 and the third inclined surface 905 are inclined toward the push plate 8, and the second inclined surface 903 and the fourth inclined surface 906 are inclined away from the push plate 8. One end of the first plane 901 is connected to one end of the first inclined surface 902, the other end of the first inclined surface 902 is connected to one end of the second inclined surface 903, the other end of the second inclined surface 903 is connected to one end of the second plane 904, and the other end of the second plane 904 is connected to one end of the third inclined surface 905; the other end of the third inclined surface 905 is connected to one end of the fourth inclined surface 906, and the other end of the fourth inclined surface 906 is connected to the other end of the first plane 901.

[0063] A quarter turn of the large pulley 401 can drive a half turn of the small pulley 601, thereby driving a half turn of the push shaft 6. When the push shaft 6 rotates, the push sleeve 7 can be driven to rotate through the interference between the chute 602 and the protrusion 701, thereby driving the roller 703 to rotate through the baffle 702.

[0064] The initial position of the roller 703 is located at the connection between the first plane 901 and the first inclined surface 902; when the roller 703 rotates, it will first roll on the first inclined surface 902 toward the connection between the first inclined surface 902 and the second inclined surface 903. At this time, through the interference between the roller 703 and the first inclined surface 902, the baffle 702 will approach the push plate 8, and the large spring 10 will be compressed, thereby driving the pushing sleeve 7 to approach the hopper 16. In this process, the protrusion 701 slides in the slide groove 602, and the push plate 8 approaches the hopper 16. The ultrasonic transducer is driven by the push plate 8 to slide toward the turntable 13 in the feed trough 102; when the roller 703 rolls to the connection between the first inclined surface 902 and the second inclined surface 903, the ultrasonic All the wave transducers enter the turntable 13; then the roller 703 continues to rotate, and under the elastic force of the large spring 10, the roller 703 will roll on the second inclined surface 903. At this time, the baffle 702 will drive the pushing sleeve 7 to move away from the push plate 8; when the roller 703 rolls to the connection between the second inclined surface 903 and the second plane 904, the push plate 8 completely leaves the detection range of the detector 17; then the roller 703 will roll on the second plane 904 to the connection with the third inclined surface 905; to keep the position of the push plate 8 unchanged; to prevent the push plate 8 from affecting the detection accuracy of the detector 17; at this time, the driving wheel 3 is disengaged from the first driven wheel 4, the driving wheel 3 continues to rotate, and the first driven wheel 4 stops rotating.

[0065] As the driving wheel 3 continues to rotate, the detector 17 will operate and cooperate with the second driven wheel 5 to detect the surface size of the ultrasonic transducer; after the detector 17 completes the detection, the driving wheel 3 will cooperate with the first driven wheel 4 again to drive the pusher shaft 6 to rotate half a circle.

[0066] The rotating pushing shaft 6 will drive the roller 703 to rotate, thereby driving the roller 703 to roll on the third inclined surface 905 first, and through the resistance between the roller 703 and the third inclined surface 905, drive the push plate 8 toward the hopper 16, so as to drive the ultrasonic transducer to separate from the turntable 13, and slide in the discharge trough 103 until it enters the hopper 16; then the roller 703 will roll on the fourth inclined surface 906, and drive the push plate 8 away from the hopper 16 through the elastic force of the large spring 10; when the roller 703 reaches the first plane 901, it rolls on the first plane 901 to the connection with the first inclined surface 902, completing the reset.

[0067] The ultrasonic transducer is driven by the pushing mechanism to move into the detection range of the detector 17, and the surface flatness of the ultrasonic transducer can be detected during the movement; when the detector 17 is performing the detection, the pushing mechanism will be separated from the ultrasonic transducer to avoid the pushing mechanism affecting the detection accuracy of the detector 17; after the detection is completed, the pushing mechanism will push the ultrasonic transducer to move into the hopper 16 for the next product to be detected.

[0068] As a further solution of the present invention, a horizontal rotating shaft 11 and a vertical rotating shaft 12 are rotatably installed on the chassis 1, and a small gear 1101 engaged with the large gear 501 is installed on the horizontal rotating shaft 11; a worm 1102 is installed on the horizontal rotating shaft 11, and a worm wheel 1201 cooperating with the worm 1102 is installed on the vertical rotating shaft 12; and the vertical rotating shaft 12 is connected to the turntable 13.

[0069] In this embodiment, when the large gear 501 rotates, it drives the small gear 1101 to rotate several times, thereby driving the horizontal shaft 11 to rotate, and thus driving the worm 1102 to rotate. The meshing action drives the worm wheel 1201 to rotate, thereby driving the turntable 13 to rotate through the vertical shaft 12.

[0070] That is, after the push plate 8 drives the ultrasonic transducer to move to the turntable 13, it will separate from the ultrasonic transducer. At this time, the detector 17 detects the ultrasonic transducer on the turntable 13. After that, the turntable 13 drives the ultrasonic transducer to rotate a certain angle, and the detector 17 detects the rotated ultrasonic transducer again; through multi-angle detection, it can be more accurately judged whether the surface size of the ultrasonic transducer meets the production requirements; after multiple angle detections are completed, the push plate 8 will drive the ultrasonic transducer to move to complete the discharging.

[0071] As a further solution of the present invention, multiple groups of make-shift grooves 104 are symmetrically opened on the detection platform 101, and a stopper 14 is slidably embedded in the make-shift groove 104. A small spring 15 is provided in the make-shift groove 104, and the two ends of the small spring 15 respectively conflict with the stopper 14 and the detection platform 101.

[0072] In this embodiment, when the push plate 8 drives the ultrasonic transducer to move onto the turntable 13, the stopper 14 can contact the ultrasonic transducer to prevent the ultrasonic transducer from overturning when entering the turntable 13, which would cause inaccurate detection results of the detector 17.

[0073] When the push plate 8 approaches the hopper 16, it pushes the ultrasonic transducer to collide with the stopper 14, and the circumferential surface of the ultrasonic transducer cooperates with the stopper 14 to drive the stopper 14 to slide in the clearance groove 104, compressing the small spring 15; and after the ultrasonic transducer passes over the stopper 14, the elastic force of the small spring 15 drives the stopper 14 to reset.

[0074] As a further solution of the present invention, multiple groups of ramps 105 are symmetrically opened on the detection platform 101, and the ramps 105 are connected to the discharge trough 103. The detection platform 101 is equipped with a classification motor 18, and a rotating plate 19 is installed on the output end of the classification motor 18; and the rotating plate 19 is located between the multiple groups of ramps 105.

[0075] In this embodiment, after the detector 17 detects the ultrasonic transducer, the system controls the classification motor 18 to rotate according to the detection result (qualified or unqualified), thereby driving the rotating plate 19 to rotate; when the rotating plate 19 rotates toward the ramp 105 on one side, the rotating plate 19 will block the discharge trough 103 and the ramp 105 on the side of the rotation direction. At this time, the ultrasonic transducer will slide from the discharge trough 103 to the other ramp 105, and slide from the ramp 105 into the hopper 16 corresponding to this ramp 105.

[0076] After detection by the detector 17, the ultrasonic transducers will be divided into qualified and unqualified sizes. The detector 17 controls the rotation of the rotating plate 19, and the rotating plate 19 divides the ramp 105 into qualified channels and unqualified channels. That is, the qualified parts and unqualified parts leave the chassis 1 and enter the hopper 16 that is different.

[0077] As a further solution of the present invention, multiple groups of buffer plates 1601 are installed in the hopper 16.

[0078] In this embodiment, when the ultrasonic transducer slides down the ramp 105 into the hopper 16, it first contacts the buffer plate 1601. The buffer plate 1601 acts as a buffer to reduce the kinetic energy of the ultrasonic transducer's fall, thereby preventing wear and damage to the ultrasonic transducer during the fall.

[0079] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
