Description

Technical Field

[0001] The invention belongs to the technical field of ultrasonic transducer performance testing, and in particular relates to an ultrasonic transducer performance testing device. Background Art

[0002] Ultrasonic transducer is a device that converts electromagnetic energy into mechanical energy (sound energy). Ultrasonic transducers are usually made of piezoelectric ceramics or other magnetostrictive materials. Its function is to convert the input electrical power into mechanical power (i.e. ultrasonic waves) and then transmit it out, while consuming very little power itself. Common applications include ultrasonic cleaners, ultrasonic atomizers, B-ultrasound probes, etc.

[0003] In the prior art, the performance of ultrasonic transducers needs to be tested after production to ensure whether the performance of the equipment is normal, so as to obtain more accurate measurement results; and the resonance curve test is an important method for evaluating the performance of ultrasonic transducers. Through the resonance curve test, the frequency characteristics, impedance characteristics, bandwidth and other parameters of the ultrasonic transducer can be understood, so as to evaluate its performance. Usually, an impedance analyzer is used to perform a resonance curve test on the ultrasonic transducer. During the test, the wiring clamp of the impedance analyzer needs to be connected to the wiring terminal of the ultrasonic transducer. When connecting the two, attention should be paid to the positive and negative poles of the wiring, that is, the positive pole should be connected to the positive pole, and the negative pole should be connected to the negative pole. If the staff connects the wiring reversely or clamps it biasedly, it will cause inaccurate test results, and it may also cause certain impacts on the equipment, thereby affecting the test efficiency and effect of the ultrasonic transducer.

[0037] Example 1: Please refer to Figure 1-6 The present invention provides an ultrasonic transducer performance testing device, comprising a test bench 1, and further comprising:

[0038] A placement seat 2 is fixed to the top surface of the test bench 1. A fixing plate 3 corresponding to the placement seat 2 is fixed to the top surface of the test bench 1. A card slot 4 is provided on the top surface of the placement seat 2 corresponding to the fixing plate 3. A tester 5 is placed on the top surface of the test bench 1. The wiring terminals of the tester 5 are connected to two wiring clips 6.

[0039] A movable groove 7 is provided on the top surface of the fixed plate 3, and a movable seat 8 is slidably connected to the inner wall of the movable groove 7, and an L-shaped mounting rod 9 is fixed to the top surface of the movable seat 8, and connecting blocks 10 are fixed on both sides of the L-shaped mounting rod 9, and the ends of the two connecting blocks 10 are respectively fixed to the bottom opposite surfaces of the two wiring clips 6, and a fixing rod 11 is fixed to one side of the L-shaped mounting rod 9, and an opening and closing mechanism 12 is provided on the surface of the fixing rod 11 corresponding to the two wiring clips 6;

[0040] The limiting plates 13 are provided with two and are respectively slidably connected to the two sides of the placement seat 2, wherein the limiting plates 13 are U-shaped; the limiting plates 13 on both sides of the placement seat 2 are provided with a push-pull mechanism 14 that cooperates with the opening and closing mechanism 12; the base 1 is provided with a bracket for placing the ultrasonic transducer, thereby facilitating the placement of the ultrasonic transducer.

[0041] It is worth noting that the tester 5 is an impedance analyzer, and the impedance analyzer is externally connected to a power supply, and the impedance analyzer is used to perform a performance test on the resonance curve of the ultrasonic transducer; the card slot 4 is adapted to the size of the connection terminal of the ultrasonic transducer.

[0042] Further as Figure 2 and Figure 3 As shown, it is worth to explain in detail that the opening and closing mechanism 12 includes:

[0043] A movable rod 121, which is movable and penetrates the top surface of the fixed rod 11, and the end of the movable rod 121 is rotatably connected to a T-shaped connecting rod 122, and the end of the T-shaped connecting rod 122 is fixed to the top opposite surface of the two wiring clamps 6, and a U-shaped mounting block 123 is fixed to the bottom end of the movable rod 121, and a roller 124 is rotatably connected inside the U-shaped mounting block 123;

[0044] Spring 125, spring 125 is sleeved on the outer surface of the movable rod 121, the top end of the spring 125 is fixed to the bottom surface of the fixed rod 11, the bottom end of the spring 125 is fixed to the top surface of the U-shaped mounting block 123, and the upper end of the fixed plate 3 is provided with a driving component 126 that cooperates with the push-pull mechanism 14.

[0045] It is worth noting that when the roller 124 is not subjected to force, the movable rod 121 is pulled down by the elastic force of the spring 125, thereby keeping the two wiring clamps 6 in an unfolded state.

[0046] Further as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it is worth noting that the drive assembly 126 includes:

[0047] A first rack 1261, which is disposed at the upper end of the movable groove 7, a bevel block 1262 matching the roller 124 is fixed to one side of the top surface of the first rack 1261, and a movable hole 1263 is opened on the surface of the L-shaped mounting rod 9 corresponding to the bevel block 1262;

[0048] The second rack 1264 is fixed to the top surface of the L-shaped mounting rod 9, and the first mounting frame 1265 is fixed to the top surface of the fixing plate 3. The inner side of the first mounting frame 1265 is rotatably connected to a gear 1266 that matches the second rack 1264, and the gear 1266 is meshed with the first rack 1261 for transmission.

[0049] It is worth noting that when the roller 124 is located above the first rack 1261, the roller 124 contacts but is tightly attached to the surface of the first rack 1261 under the elastic force of the spring 125; a small part of the bottom surface of the first rack 1261 is smooth, and the length of the smooth area is adapted to the length of the bevel block 1262, so that when the bevel block 1262 squeezes the roller 124, the first rack 1261 does not engage with the gear 1266.

[0050] Further as Figure 1 , Figure 4 and Figure 6 As shown, it is worth to explain in detail that the push-pull mechanism 14 includes:

[0051] L-shaped push rods 141, two L-shaped push rods 141 are provided and are respectively fixed on both sides of the first rack 1261, the ends of the two L-shaped push rods 141 are respectively fixed to the surfaces of the two limit plates 13, and both sides of the placement seat 2 are provided with limit sliding grooves 142 that match the limit plates 13, and the inner walls of the two limit sliding grooves 142 are fixed with limit rods 143, and the limit rods 143 movably penetrate the limit plates 13;

[0052] The pull ring 144 is arranged on the periphery of the placement seat 2 and the ends are respectively fixed to the surfaces of the two limit plates 13. Two symmetrically distributed second mounting frames 145 are fixed to the top surface of the fixing plate 3. The two L-shaped push rods 141 are respectively slidably mounted on the outer surfaces of the two second mounting frames 145.

[0053] It is worth explaining in detail that the second mounting frame 145 limits the L-shaped push rod 141 to maintain the stability of the L-shaped push rod 141 when it moves horizontally; the limiting plate 13 slides in the limiting slide groove 142, and the limiting plate 13 is limited by the limiting rod 143 to improve the stability of the limiting plate 13 when it moves.

[0054] Embodiment 2: Based on Embodiment 1, according to Figure 3 As shown, it is worth explaining in detail that a support rod 15 is fixed to the top surface of the fixed rod 11, and the top surface of the support rod 15 is rotatably connected to a T-shaped clamping rod 16 that cooperates with the two limiting plates 13, and the top surface of the fixed rod 11 is provided with a limiting piece 17 that cooperates with the T-shaped clamping rod 16.

[0055] It is worth explaining in detail that after the two terminal clamps 6 clamp the terminal of the ultrasonic transducer, the staff can flip the T-shaped clamp 16 so that the T-shaped clamp 16 is clamped on one side of the two limit plates 13, thereby limiting the two limit plates 13 to avoid the situation where the pull ring 144 is pulled accidentally during the detection process and cause the terminal clamp 6 to fall off.

[0056] Further as Figure 2 and Figure 3 As shown, it is worth explaining in detail that the limit member 17 includes a rectangular through hole 171 opened on the top surface of the T-shaped connecting rod 122, a support rod 172 is fixed to the top surface of the fixing rod 11, the end of the support rod 172 passes through the rectangular through hole 171, and an elastic clamping ring 173 that cooperates with the T-shaped clamping rod 16 is fixed to the top end of the support rod 172, and a top rod 18 that cooperates with the T-shaped clamping rod 16 and is inclined is fixed to the top surface of the U-shaped mounting block 123.

[0057] It is worth explaining in detail that when the terminal clamp 6 is not subjected to clamping detection, the T-shaped clamp rod 16 is flipped over and clamped in the elastic clamp ring 173, thereby limiting the position of the T-shaped clamp rod 16. During the movement detection process of the terminal clamp 6, the U-shaped mounting block 123 drives the push rod 18 to move upward, thereby pushing the T-shaped clamp rod 16 out of the elastic clamp ring 173, so that after the terminal clamp 6 is clamped, it is convenient for the staff to flip the T-shaped clamp rod 16 and further limit the position of the terminal clamp 6.

[0058] Further as Figure 5 As shown, it is worth explaining in detail that two symmetrically distributed sliding rods 19 are fixed to the inner wall of the movable groove 7, and the two sliding rods 19 movably penetrate the movable seat 8. The movable seat 8 is limited by the two sliding rods 19 to maintain the stability of the movable seat 8 when sliding in the movable groove 7.

[0059] The scheme has the following working process: the staff first observes that the positive and negative poles of the ultrasonic transducer terminal correspond to the two wiring clips 6, and then places the terminal in the slot 4 of the placement seat 2. The positions of the positive and negative poles of the two wiring clips 6 are fixed, so it is convenient for the staff to identify them, and then push the pull ring 144 to push the two limit plates 13 to move. The limit plates 13 move to the top of the slot 4, thereby limiting the terminal of the ultrasonic transducer. The two limit plates 13 are connected to the limit slide 14 through the limit rod 143. 2 is limited, and the limiting plate 13 pushes the two L-shaped push rods 141 to move during the movement, and the L-shaped push rods 141 drive the first rack 1261 to move, thereby driving the inclined block 1262 to move in the direction away from the placement seat 2, and at this time, under the elastic force of the spring 125, the U-shaped mounting block 123 is pushed down, thereby driving the movable rod 121 to move down, and then pulling down the T-shaped connecting rod 122, so that the wiring clamp 6 is in an open state, and the first rack 1261 drives the gear 1266 on the first mounting frame 1265 during the movement. The gear 1266 drives the second rack 1264 to move toward the placement seat 2, thereby driving the L-shaped mounting rod 9 and the movable seat 8 to move on the fixed plate 3, so that the ends of the two wiring clips 6 extend into the wiring terminals of the ultrasonic transducer. At this time, the pull ring 144 is continuously pushed to make the first rack 1261 continue to move. At this time, the first rack 1261 is disengaged from the gear 1266. At this time, the inclined block 1262 moves and drives the roller 124 to move up on the inclined surface of the inclined block 1262. When the U-shaped mounting block 123 moves up, it pushes The movable rod 121 moves upward, thereby driving the terminal clamp 6 to close through the T-shaped connecting rod 122, thereby clamping the internal connector of the terminal, and then completing the docking of the terminal clamp 6 of the tester 5 with the terminal of the ultrasonic transducer, and then proceeding to the next step of performance testing. When the U-shaped mounting block 123 moves upward, the push rod 18 is driven to push the T-shaped clamp rod 16, so that the T-shaped clamp rod 16 is separated from the elastic clamp ring 173, and the staff flips the T-shaped clamp rod 16 and clamps it on one side of the two limit plates 13, so as to maintain the stability of the terminal clamp 6 after docking.
