Description

Technical Field

[0001] The invention relates to the technical field of fast ultrasonic microscopic imaging devices, and in particular to a fast ultrasonic microscopic imaging device. Background Art

[0002] Ultrasonic microscopy is an advanced instrument that combines ultrasonic technology and microscope observation. It is used for non-destructive internal structure analysis of biological tissues, materials or cells. The device usually consists of an ultrasonic generator, a scanner, a sample stage and a microscope. The ultrasonic generator generates high-frequency sound waves, which are transmitted to the sample through the scanner. When the sound waves propagate inside the sample, reflected waves are generated. These reflected waves are received by the scanner and transmitted to the signal processing system. The signal processing system analyzes these reflected waves and converts the data into images, which are displayed on the connected microscope.

[0003] When using the current fast ultrasonic microscopy imaging device, staff often find that sometimes in order to improve the detection efficiency, a large number of small-packaged components are detected at the same time. In order to prevent the drift of components caused by water flow, the current ultrasonic microscopy imaging device will stick a layer of double-sided tape on the sample board, and then stick the components on the sample board. When removing the components, it is easy to damage the pins of the components, and the surface of the pins will be stained with foreign matter, which will affect the product quality. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a fast ultrasonic microscopic imaging device.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a fast ultrasonic microscopy imaging device, comprising a shell, a fixed plate fixedly connected to the shell, a slide groove is provided on the fixed plate, a slider is slidably connected in the slide groove, an ultrasonic transducer is fixedly connected to the slider through a cylinder, a reciprocating screw is rotatably connected in the slide groove, a first motor is fixedly connected to the shell, an output shaft of the first motor is fixedly connected to the reciprocating screw, a water tank is fixedly connected to the shell, a clamping structure is provided on the water tank, the clamping structure is mainly composed of a sample table, the sample table is provided in the water tank, a plurality of clamping grooves are provided on the sample table, two clamping plates are slidably connected in the clamping groove, and a rubber pad is fixedly connected to the clamping plate.

[0006] The effects achieved by the above components are as follows: a coupling medium is introduced into the water tank, the object to be tested is placed in the water tank, the first motor is started, and the output shaft of the first motor drives the reciprocating screw to rotate. Since the slider slides in a limited position in the slide slot, the reciprocating screw can drive the slider to slide back and forth, thereby driving the ultrasonic transducer to detect the object to be tested. The ultrasonic transducer emits high-frequency ultrasonic waves and receives reflected sound waves. These sound waves will generate echoes due to the difference in acoustic impedance of different media inside the object to be tested. These echoes are then captured by the detector and converted into electrical signals. By analyzing these signals, the object to be tested can be constructed. To image the interior, place several samples on the sample table, slide two clamping plates relative to each other, so that the two clamping plates clamp a sample and limit it, so that the sample is stable and easy to remove. The rubber pad can prevent the rigid contact between the clamping plate and the sample from causing damage to it, thereby avoiding the current ultrasonic microscopy imaging device. In order to prevent the drift of components caused by water flow, a layer of double-sided tape will be attached to the sample plate, and then the components will be attached to the sample plate. When removing the components, it is easy to damage the pins of the components, and foreign matter will be stained on the surface of the pins, which will affect the product quality.

[0007] Preferably, the sample table is provided with two sliding grooves, a sliding block is slidably connected in the sliding groove, and a connecting rod is fixedly connected to the two sliding blocks.

[0009] Preferably, a first spring is provided in the clamping groove, and two ends of the first spring are respectively fixedly connected to the clamping plate.

[0010] The effect achieved by the above components is: when the connecting rod pushes the two clamping plates closer to each other to clamp the sample, the first spring is in a contracted state, so the rebound force of the first spring acts on the two clamping plates. When sliding off the connecting rod, each clamping plate slides in the opposite direction under the action of the rebound force of the first spring, making it convenient to remove the sample.

[0011] Preferably, a bidirectional screw is rotatably connected in one of the sliding grooves, the two sections of threads on the bidirectional screw are in opposite directions, the bidirectional screw is threadedly connected to the two sliding blocks, a second motor is fixedly connected to the sample table, and the output shaft of the second motor is fixedly connected to the bidirectional screw.

[0012] The effect achieved by the above components is: start the second motor, and the output shaft of the second motor drives the bidirectional screw to rotate. Since the two sliding blocks slide in the sliding groove, rotating the bidirectional screw can drive the two sliding blocks to slide in opposite directions synchronously, making the clamping more stable and the operation more convenient.

[0013] Preferably, an adjustment structure is provided on the water tank, and the adjustment structure is mainly composed of two adjustment grooves, which are respectively opened on the inner walls on both sides of the water tank, and an adjustment block is slidably connected in the adjustment groove, and the adjustment block is fixedly connected to the sample table.

[0014] The effect achieved by the above components is: the sample stage can be driven up or down by the sliding adjustment block, so that the sample stage can be easily moved out of the coupling medium, and the sample can be easily placed and removed without the staff having to put their hands into the coupling medium.

[0015] Preferably, two racks are fixedly connected to one side of the sample stage, and gears are meshedly connected to the racks, and the gears are rotatably connected to the inner wall of the water tank.

[0016] The effect achieved by the above components is that the synchronous rotation of the two rotating gears can drive the two racks to move synchronously, thereby driving the sample stage to move up and down.

[0017] Preferably, a round rod is fixedly connected to the two gears, a third motor is fixedly connected to the water tank, and an output shaft of the third motor is fixedly connected to the round rod.

[0018] The effect achieved by the above components is: starting the third motor, the output shaft of the third motor drives the round rod to rotate, and the two third motors can be driven to rotate synchronously, making the operation more convenient.

[0019] Preferably, a rectangular plate is fixedly connected to one side of the sample table, a plurality of triangular blocks are fixedly connected to the rectangular plate, and a limit block is arranged on the water tank.

[0020] The effect achieved by the above components is: after the position of the sample stage is adjusted, the limit block is inserted between the two triangular blocks, and the upper surface of the limit block is against the lower surface of a triangular block, which can limit the rectangular plate, thereby preventing the sample stage from sliding down under the action of gravity, making the position of the sample stage more stable.

[0021] Preferably, a fixing block is fixedly connected to the water tank, a sliding rod is slidably inserted into the fixing block, one end of the sliding rod is fixedly connected to a connecting rod, and the connecting rod is fixedly connected to the limiting block.

[0022] The effect achieved by the above components is that the slide bar slides on the upper limit of the fixed block, which can make the movement process of the limit block more stable.

[0023] Preferably, a second spring is sleeved on the sliding rod, one end of the second spring is fixedly connected to the connecting rod, and the other end of the second spring is fixedly connected to the fixing block.

[0024] The effect achieved by the above components is: during the rising process of the rectangular plate, the upper surface of the triangular block will push the lower surface of the limit block, causing the limit block to slide to the left, and then drive the slide bar to slide to the left. At this time, the second spring is in a contracted state. When the limit block moves between the lower two triangular blocks, the limit block will slide to the right under the action of the rebound force of the second spring and clamp the triangular block. The rectangular plate can be limited continuously in this reciprocating manner. If the sample table needs to be slid downward, just pull the slide bar outward to drive the limit block away from the triangular block, making the operation more convenient.

[0025] Compared with the prior art, the advantages and positive effects of the present invention are that, in the present invention, by setting a clamping structure, a plurality of samples are placed on the sample table, and two clamping plates are slid relative to each other so that the two clamping plates clamp a sample and limit it, so that the sample is stable and easy to remove, and the rubber pad can prevent the rigid contact between the clamping plate and the sample from causing damage to it, and the sliding block can be slid to drive the connecting rod to move, and the connecting rod can push a plurality of clamping plates to move synchronously without sliding one by one, so that the clamping operation is more convenient, and when the connecting rod pushes the two clamping plates to approach each other to clamp the sample, the first spring is in a contracted state, so the rebound elastic force of the first spring acts on the two clamping plates When sliding off the connecting rod, each clamping plate will slide in the opposite direction under the action of the rebound force of the first spring, which is convenient for removing the sample, and starting the second motor. The output shaft of the second motor drives the bidirectional screw to rotate. Since the two sliding blocks slide in the sliding groove, rotating the bidirectional screw can drive the two sliding blocks to slide synchronously in the opposite direction, making the clamping more stable and the operation more convenient, thereby avoiding the current ultrasonic microscopy imaging device to prevent the drift of components caused by water flow, and then sticking a layer of double-sided tape on the sample board, and then sticking the components on the sample board. When removing the components, it is easy to damage the pins of the components, and the surface of the pins will be stained with foreign matter, which affects the product quality.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Embodiment 1, as Figure 1 and Figure 2 As shown, a fast ultrasonic microscopy imaging device includes a shell 1, a fixed plate 2 is fixedly connected to the shell 1, a slide groove 3 is opened on the fixed plate 2, a slider 4 is slidably connected in the slide groove 3, an ultrasonic transducer 5 is fixedly connected to the slider 4 through a cylinder, a reciprocating screw 6 is rotatably connected in the slide groove 3, a first motor 9 is fixedly connected to the shell 1, the output shaft of the first motor 9 is fixedly connected to the reciprocating screw 6, and a water tank 10 is fixedly connected to the shell 1.

[0036] Reference Figure 5A clamping structure 7 is provided on the water tank 10. The clamping structure 7 is mainly composed of a sample table 71. The sample table 71 is provided in the water tank 10. A plurality of clamping grooves 72 are provided on the sample table 71. Two clamping plates 73 are slidably connected in the clamping grooves 72. A rubber pad 75 is fixedly connected to the clamping plate 73. A coupling medium is introduced into the water tank 10. The object to be tested is placed in the water tank 10. The first motor 9 is started. The output shaft of the first motor 9 drives the reciprocating screw 6 to rotate. Since the slider 4 slides in the slide groove 3, the reciprocating screw 6 can drive the slider 4 to slide back and forth, thereby driving the ultrasonic transducer 5 to detect the object to be tested. The ultrasonic transducer 5 emits high-frequency ultrasonic waves and receives the reflected sound waves. These sound waves will be detected by the internal The difference in acoustic impedance of different media generates echoes, which are then captured by the detector and converted into electrical signals. By analyzing these signals, an image of the interior of the object to be tested can be constructed. Several samples are placed on the sample table 71, and two clamping plates 73 are slid relative to each other so that the two clamping plates 73 clamp a sample and limit it, making the sample stable and easy to remove. The rubber pad 75 can prevent the clamping plates 73 from being damaged by the rigid contact with the sample, thereby avoiding the current ultrasonic microscopy imaging device. In order to prevent the drift of components caused by water flow, a layer of double-sided tape will be attached to the sample plate, and then the component will be attached to the sample plate. When the component is removed, it is easy to damage the pins of the component and cause the pins to In order to prevent the surface from being stained with foreign matter and thus affecting the product quality, two sliding grooves 76 are provided on the sample table 71, and a sliding block 77 is slidably connected in the sliding groove 76. A connecting rod 78 is fixedly connected to the two sliding blocks 77. The sliding block 77 can be slid to drive the connecting rod 78 to move. The connecting rod 78 can push a plurality of clamping plates 73 to move synchronously without sliding one by one, making the clamping operation more convenient. A first spring 74 is provided in the clamping groove 72, and the two ends of the first spring 74 are respectively fixedly connected to the clamping plates 73. When the connecting rod 78 pushes the two clamping plates 73 to approach each other to clamp the sample, the first spring 74 is in a contracted state, so the rebound elastic force of the first spring 74 acts on the two clamping plates 73. When sliding off the connecting rod 78, each clamping plate 73 slides in the opposite direction under the action of the rebound force of the first spring 74, which makes it easy to remove the sample. A bidirectional screw 79 is rotatably connected in a sliding groove 76. The two sections of threads on the bidirectional screw 79 are in opposite directions. The bidirectional screw 79 is threadedly connected to two sliding blocks 77. A second motor 710 is fixedly connected to the sample table 71. The output shaft of the second motor 710 is fixedly connected to the bidirectional screw 79. The second motor 710 is started, and the output shaft of the second motor 710 drives the bidirectional screw 79 to rotate. Since the two sliding blocks 77 slide in a limited position in the sliding groove 76, rotating the bidirectional screw 79 can drive the two sliding blocks 77 to slide in opposite directions synchronously, making the clamping more stable and the operation more convenient.

[0037] Reference Figures 4 to 6The water tank 10 is provided with an adjustment structure 8, which is mainly composed of two adjustment grooves 81. The two adjustment grooves 81 are respectively opened on the inner walls of both sides of the water tank 10. An adjustment block 82 is slidably connected in the adjustment groove 81. The adjustment block 82 is fixedly connected to the sample stage 71. The sample stage 71 can be driven to rise or fall by sliding the adjustment block 82, which is convenient for moving the sample stage 71 out of the coupling medium, and can be convenient for placing and removing samples without the staff reaching their hands into the coupling medium. One side of the sample stage 71 is fixedly connected with two racks 83, and a gear 84 is meshed and connected to the rack 83. The gear 84 is rotatably connected to the inner wall of the water tank 10, and the two rotating gears are rotated synchronously. 84 can drive the two racks 83 to move synchronously, thereby driving the sample stage 71 to move up and down. A round rod 86 is fixedly connected to the two gears 84. A third motor 85 is fixedly connected to the water tank 10. The output shaft of the third motor 85 is fixedly connected to the round rod 86. When the third motor 85 is started, the output shaft of the third motor 85 drives the round rod 86 to rotate, which can drive the two third motors 85 to rotate synchronously, making the operation more convenient. A rectangular plate 87 is fixedly connected to one side of the sample stage 71. A plurality of triangular blocks 88 are fixedly connected to the rectangular plate 87. A limit block 89 is set on the water tank 10. After the position of the sample stage 71 is adjusted, the limit block 89 is clamped into the two triangular blocks 88. The upper surface of the limit block 89 abuts against the lower surface of a triangular block 88, which can limit the rectangular plate 87, thereby preventing the sample stage 71 from sliding down under the action of gravity, making the position of the sample stage 71 more stable. A fixed block 811 is fixedly connected to the water tank 10, and a sliding rod 812 is slidably inserted on the fixed block 811. One end of the sliding rod 812 is fixedly connected to a connecting rod 810. The connecting rod 810 is fixedly connected to the limit block 89. The sliding rod 812 slides in the upper limit position of the fixed block 811, which can make the movement process of the limit block 89 more stable. A second spring 813 is sleeved on the sliding rod 812, and one end of the second spring 813 is fixedly connected to the connecting rod 810. The other end of 13 is fixedly connected to the fixed block 811. During the rising process of the rectangular plate 87, the upper surface of the triangular block 88 will push the lower surface of the limit block 89, so that the limit block 89 slides to the left, thereby driving the slide bar 812 to slide to the left. At this time, the second spring 813 is in a contracted state. When the limit block 89 moves between the lower two triangular blocks 88, the limit block 89 will slide to the right under the action of the rebound force of the second spring 813 to clamp the triangular block 88. The rectangular plate 87 can be limited in this reciprocating manner. If the sample stage 71 needs to be slid downward, it only needs to pull the slide bar 812 outward to drive the limit block 89 away from the triangular block 88, making the operation more convenient.

[0038] Working principle: a coupling medium is introduced into the water tank 10, the object to be tested is placed in the water tank 10, and the first motor 9 is started. The output shaft of the first motor 9 drives the reciprocating screw 6 to rotate. Since the slider 4 slides in the slide groove 3, the reciprocating screw 6 can drive the slider 4 to slide back and forth, thereby driving the ultrasonic transducer 5 to detect the object to be tested. The ultrasonic transducer 5 emits high-frequency ultrasonic waves and receives reflected sound waves. These sound waves will generate echoes due to the difference in acoustic impedance of different media inside the object to be tested. These echoes are then captured by the detector and converted into electrical signals. By analyzing these signals, an image of the inside of the object to be tested can be constructed. Several samples are placed on the sample table 71, and two relative clamping plates 73 are slid so that the two clamping plates 73 clamp a sample. The rubber pad 75 can prevent the rigid contact between the clamping plate 73 and the sample from causing damage to the sample, thereby avoiding the situation that the current ultrasonic microscopy imaging device, in order to prevent the drift of the component caused by water flow, will stick a layer of double-sided tape on the sample plate, and then stick the component on the sample plate. When the component is removed, it is easy to damage the pin of the component, and the surface of the pin will be stained with foreign matter, which will affect the product quality. The sliding block 77 can be slid to drive the connecting rod 78 to move. The connecting rod 78 can push several clamping plates 73 to move synchronously without sliding one by one, making the clamping operation more convenient. When the connecting rod 78 pushes the two clamping plates 73 to approach each other to clamp the sample, the first spring 74 is in a contracted state. The first spring 74 is in a state, so the rebound force of the first spring 74 acts on the two clamping plates 73. When sliding off the connecting rod 78, each clamping plate 73 slides in the opposite direction under the action of the rebound force of the first spring 74, which is convenient for removing the sample. The second motor 710 is started, and the output shaft of the second motor 710 drives the bidirectional screw 79 to rotate. Since the two sliding blocks 77 slide in the sliding groove 76, the rotation of the bidirectional screw 79 can drive the two sliding blocks 77 to slide synchronously in the opposite direction, making the clamping more stable and the operation more convenient. The sample stage 71 can be driven to rise or fall by the sliding adjustment block 82, which is convenient for moving the sample stage 71 out of the coupling medium, and the sample can be conveniently placed and removed without the staff reaching their hands into the coupling medium. The synchronous rotation of the two rotating gears 84 can drive the two gears The bar 83 moves synchronously, thereby driving the sample stage 71 to move up and down, and the third motor 85 is started. The output shaft of the third motor 85 drives the round rod 86 to rotate, which can drive the two third motors 85 to rotate synchronously, making the operation more convenient. After the position of the sample stage 71 is adjusted, the limit block 89 is inserted between the two triangular blocks 88. The upper surface of the limit block 89 is against the lower surface of a triangular block 88, which can limit the rectangular plate 87, thereby preventing the sample stage 71 from sliding down under the action of gravity, making the position of the sample stage 71 more stable. The slide bar 812 slides on the upper limit of the fixed block 811, which can make the movement process of the limit block 89 more stable. During the rising process of the rectangular plate 87, the upper surface of the triangular block 88 will push the lower surface of the limit block 89, causing the limit block 89 to slide to the left.Then the slide bar 812 is driven to slide to the left, and the second spring 813 is in a contracted state. When the limit block 89 moves to between the two lower triangular blocks 88, the limit block 89 will slide to the right and clamp the triangular block 88 under the action of the rebound force of the second spring 813. In this way, the rectangular plate 87 can be continuously limited. If the sample stage 71 needs to be slid downward, it is only necessary to pull the slide bar 812 outward to drive the limit block 89 away from the triangular block 88, making the operation more convenient.
