Description

Technical Field

[0001] The present invention relates to an ultrasonic detection device using an upper probe module and a lower probe module, and more specifically, to an ultrasonic detection device using an upper probe module and a lower probe module, which can detect an object through the upper probe module and the lower probe module, and the upper probe module and the lower probe module irradiate ultrasonic waves to the object above and below the object to simultaneously detect the above and below the object. Background Art

[0002] An ultrasonic testing device is a device that irradiates an object with ultrasonic waves through a probe module, then uses the probe module to receive reflected or transmitted ultrasonic waves and form an image. Ultrasonic testing devices can detect minute defects, so ultrasonic testing devices require high resolution.

[0003] The ultrasonic detection method using the ultrasonic detection device requires a transmission medium for transmitting ultrasonic waves. Liquid is used as the ultrasonic transmission medium to prevent ultrasonic attenuation, and the commonly used liquid is water.

[0004] The existing ultrasonic detection method is to fill the water tank with water, place the product in the filled water, and then place the probe module above the object. The detection can be performed while part of the object is immersed in the filled water.

[0005] However, the conventional ultrasonic detection device equipped with a probe module above the object has the following problems: In the conventional ultrasonic detection device, the probe module that irradiates ultrasonic waves and receives reflected signals is arranged only in one direction, for example, above the object.

[0006] In the existing ultrasonic detection device, the probe module is arranged above the object, so the detection is performed above the object. However, in the object that needs to be detected above and below, if the detection is performed only above the object, it is necessary to scan below the object by reversing and moving the object after scanning above the object.

[0007] As described above, when an ultrasonic inspection device equipped with a probe module only above an object is used for inspection, a long process time is required due to inverting and moving the object. In addition, when alignment is performed by inverting and moving the object after scanning above the object, the signal processing data above and below the scanned object cannot be processed in conjunction due to position alignment tolerance.

[0008] Furthermore, if bubbles are mixed in water (which is the ultrasonic transmission medium of the ultrasonic detection device), ultrasonic attenuation may occur due to the bubbles. However, the existing ultrasonic detection device has a problem in that it is not equipped with a separate device for removing bubbles in the water supplied to the transmission medium.

[0042] The present invention relates to an ultrasonic detection device using an upper probe module and a lower probe module, and more specifically, to an ultrasonic detection device using an upper probe module and a lower probe module, which can detect an object through the upper probe module and the lower probe module, and the upper probe module and the lower probe module irradiate ultrasonic waves to the object above and below the object to simultaneously detect the upper and lower parts of the object. Hereinafter, preferred embodiments of the present invention are described in detail with reference to the accompanying drawings.

[0043] According to an embodiment of the present invention, an ultrasonic detection device using an upper probe module and a lower probe module is used to detect an object (10). The object (10) can be detected by irradiating ultrasonic waves to the object (10) and then using the probe modules to receive reflected or transmitted ultrasonic waves. The object (10) can be any product as long as it can be subjected to ultrasonic detection.

[0044] An ultrasonic detection device using an upper probe module and a lower probe module according to an embodiment of the present invention comprises a lower probe module (100), an upper probe module (200) and a trigger control unit (160).

[0045] Reference Figure 1 and Figure 2 The lower probe module (100) is equipped with a lower transducer (120) and an internal space, wherein the lower transducer (120) is arranged below the object (10) and generates or receives ultrasonic waves toward the object (10) from below the object (10), and one side of the lower transducer (120) can be inserted into the internal space, and a lower water jacket (130) is equipped in the internal space, and the lower water jacket (130) is filled with liquid.

[0046] The upper probe module (200) is equipped with an upper transducer (220) and an internal space. The upper transducer (220) is arranged above the object (10) and generates or receives ultrasonic waves to the object (10) above the object (10). One side of the upper transducer (220) can be inserted into the internal space. The internal space is equipped with an upper water jacket (230), and the upper water jacket (230) is filled with liquid.

[0047] The ultrasonic detection device according to the embodiment of the present invention detects the object (10) through ultrasonic waves. The ultrasonic detection device according to the embodiment of the present invention can detect the upper surface and the lower surface of the object (10) at the same time without inverting and moving the object (10) through the lower probe module (100) and the upper probe module (200).

[0048] Furthermore, the ultrasonic detection device according to the embodiment of the present invention can simultaneously detect the upper and lower surfaces of the object (10) by spraying liquid toward the object in the lower water jacket (130) and the upper water jacket (230) without immersing the object in liquid (which is a transmission medium for transmitting ultrasonic waves).

[0049] The trigger control unit (160) can control the time point at which the lower transducer (120) generates an ultrasonic wave and the time point at which the upper transducer (220) generates an ultrasonic wave.

[0050] When the lower probe module (100) and the upper probe module (200) are used simultaneously to detect the object (10), interference may occur between the ultrasonic waves generated from the lower transducer (120) and the upper transducer (220).

[0051] The trigger control unit (160) is used to prevent this phenomenon from occurring. By controlling the time point at which the lower transducer (120) and the upper transducer (220) generate ultrasonic waves, the trigger control unit (160) can prevent interference between the ultrasonic waves generated by the lower transducer (120) and the upper transducer (220).

[0052] The ultrasonic detection device according to the embodiment of the present invention can detect an object (10) by using an ultrasonic reflection (Echo, Reflection) method or an ultrasonic transmission (Transmission) method.

[0053] The ultrasonic echo (echo, reflection) method generates ultrasonic waves on one side (upper or lower) of an object (10) and receives reflected waves reflected from the upper and lower surfaces (or lower and upper surfaces) of the object (10). If there are problems such as cracks inside the object (10), other reflected waves can be detected between the reflected waves from the upper and lower surfaces (or lower and upper surfaces) of the object (10), thereby enabling the detection of defects in the object (10).

[0054] The ultrasonic transmission method generates ultrasonic waves on one side (above or below) of an object (10) and receives ultrasonic waves transmitted from the other side (below or above) of the object (10) to detect the object (10).

[0055] Reference Figure 2 According to an embodiment of the present invention, the central axis (121) of the lower transducer (120) of the lower probe module (100) and the central axis (221) of the upper transducer (220) of the upper probe module (200) may be located on the same line.

[0056] In addition, refer to Figure 3According to another embodiment of the present invention, the central axis (121) of the lower transducer (120) of the lower probe module (100) and the central axis (221) of the upper transducer (220) of the upper probe module (200) may not be located on the same line.

[0057] The lower probe module (100) and the upper probe module (200) can move in the x-, y-, and z-axis directions. The lower probe module (100) and the upper probe module (200) can move in the x-, y-, and z-axis directions independently, and the lower probe module (100) and the upper probe module (200) can also move in the x-, y-, and z-axis directions in a combined state.

[0058] That is, the lower probe module (100) and the upper probe module (200) may be moved independently, or the lower probe module (100) and the upper probe module (200) may be moved simultaneously in a combined state. Figure 4 The lower probe module (100) and the upper probe module (200) can detect various locations of the object (10) while moving.

[0059] Reference Figure 4 The trigger control unit (160) can adjust a trigger position (161), which is a position where the ultrasonic wave is irradiated to the object (10). Specifically, while moving the lower probe module (100) and the upper probe module (200), the trigger control unit (160) controls the time point at which the lower transducer (120) and the upper transducer (220) generate the ultrasonic wave, and the trigger position (161) can be adjusted, which is a position where the ultrasonic wave is irradiated to the object (10).

[0060] Reference Figure 2 According to one embodiment of the present invention, when the central axis (121) of the lower transducer (120) of the lower probe module (100) and the central axis (221) of the upper transducer (220) of the upper probe module (200) are located on the same line, both the ultrasonic reflection (Echo, Reflection) method and the ultrasonic transmission (Transmission) method can be used.

[0061] Specifically, the ultrasonic signals generated by the lower transducer (120) of the lower probe module (100) and the upper transducer (220) of the upper probe module (200) sense the signals reflected by each layer of the object (10), thereby being able to detect the object (10) above and below the object (10) by a reflection method.

[0062] At this time, if the lower transducer (120) of the lower probe module (100) and the upper transducer (220) of the upper probe module (200) generate ultrasonic signals at the same time, interference may occur between the ultrasonic signals.

[0063] Reference Figure 5 In order to prevent interference between the ultrasonic signals generated from the lower transducer (120) and the upper transducer (220), the trigger control unit (160) can cause the upper transducer (220) to generate ultrasonic waves after a specified time after causing the lower transducer (120) to generate ultrasonic waves, or cause the lower transducer (120) to generate ultrasonic waves after a specified time after causing the upper transducer (220) to generate ultrasonic waves.

[0064] Reference Figure 5 , when the upper probe module (200) and the lower probe module (100) are used for detection at a trigger position (161), the time (t up ) and the time (t down ) may be less than the time (t move ) and.

[0065] As described above, when the upper probe module (200) and the lower probe module (100) are used to detect at a trigger position (161), the time (t up ) and the time (t down ) may be less than the time (t move ), and at the same time, there is a time difference between the time points at which the upper transducer (220) and the lower transducer (120) generate ultrasonic waves. In this way, the object (10) can be detected at a trigger position (161) by a reflection method without causing ultrasonic interference.

[0066] Wherein, the time (t move ) can be derived by considering the distance (d) between one trigger position (161) and another trigger position (161), and the speed v at which the lower probe module (100) and the upper probe module (200) move.

[0067] In terms of the transmission method, the ultrasonic signals generated by the lower transducer (120) of the lower probe module (100) and the upper transducer (220) of the upper probe module (200) sense the signals transmitted by the object (10), thereby enabling the object (10) to be detected above and below the object (10) by the transmission method.

[0068] According to an embodiment of the present invention, the lower probe module (100) may be equipped with a first receiving unit (122), which receives the ultrasonic wave generated by the upper transducer (220) of the upper probe module (200), or receives the ultrasonic wave generated by the lower transducer (120) of the lower probe module (100); and the upper transducer (220) may be equipped with a second receiving unit (222), which receives the ultrasonic wave generated by the lower transducer (120) of the lower probe module (100), or receives the ultrasonic wave generated by the upper transducer (220) of the upper probe module (200).

[0069] When the central axis (121) of the lower transducer (120) of the lower probe module (100) and the central axis (221) of the upper transducer (220) of the upper probe module (200) are located on the same line, the ultrasonic signal generated from the lower transducer (120) and transmitted through each layer of the object (10) can be received by the second receiving unit (222), thereby enabling detection of the object (10).

[0070] When the central axis (121) of the lower transducer (120) of the lower probe module (100) and the central axis (221) of the upper transducer (220) of the upper probe module (200) are located on the same line, the ultrasonic signal generated from the upper transducer (220) and transmitted through each layer of the object (10) can be received by the first receiving unit (122), thereby enabling detection of the object (10).

[0071] In the ultrasonic transmission method, it is difficult to align the acoustic axes of the transmitting unit (transducer) that generates ultrasonic waves and the receiving unit that receives ultrasonic waves. Therefore, it is necessary to accurately align the acoustic axes of the transmitting unit and the receiving unit to accurately detect the object (10).

[0072] However, as in one embodiment of the present invention, if the central axis (121) of the lower transducer (120) of the lower probe module (100) and the central axis (221) of the upper transducer (220) of the upper probe module (200) are located on the same line, and the first receiving unit (122) is provided on the lower probe module (100) and the second receiving unit (222) is provided on the upper probe module (200), then the same ultrasonic signal with the maximum size for the same object (10) can be determined by comparing the signals aligned relative to the acoustic axis above and below the object (10), thereby optimizing the acoustic axis alignment.

[0073] In addition, as in one embodiment of the present invention, the central axis (121) of the lower transducer (120) of the lower probe module (100) and the central axis (221) of the upper transducer (220) of the upper probe module (200) are located on the same line, and the first receiving unit (122) is provided on the lower probe module (100) and the second receiving unit (222) is provided on the upper probe module (200), thereby optimizing the acoustic axis alignment, so that the position error can be minimized when the reflection method is used simultaneously above and below the same object (10).

[0074] According to an embodiment of the present invention, the first receiving unit (122) can also receive ultrasonic waves generated by the lower transducer (120) of the lower probe module (100). That is, the first receiving unit (122) can receive ultrasonic waves generated by the upper transducer (220), and the first receiving unit (122) can also receive ultrasonic waves generated by the lower transducer (120) and then returned to the lower transducer (120).

[0075] In addition, the first receiving unit (122) can be arranged inside the lower transducer (120), and the first receiving unit (122) can also be arranged outside the lower transducer (120).

[0076] In addition, the first receiving unit (122) can be configured inside the trigger control unit (160), and the first receiving unit (122) can also be configured outside the trigger control unit (160).

[0077] According to an embodiment of the present invention, the second receiving unit (222) can also receive ultrasonic waves generated by the upper transducer (220) of the upper probe module (200). That is, the second receiving unit (222) can receive ultrasonic waves generated by the lower transducer (120), and the second receiving unit (222) can also receive ultrasonic waves generated by the upper transducer (220) and then returned to the upper transducer (220).

[0078] In addition, the second receiving unit (222) can be arranged inside the upper transducer (220), and the second receiving unit (222) can also be arranged outside the upper transducer (220).

[0079] In addition, the second receiving unit (222) can be configured inside the trigger control unit (160), and the second receiving unit (222) can also be configured outside the trigger control unit (160).

[0080] According to an embodiment of the present invention, an ultrasonic reflection (Echo, Reflection) method or an ultrasonic transmission (Transmission) method may also be used in combination. When the central axis (121) of the lower transducer (120) of the lower probe module (100) and the central axis (221) of the upper transducer (220) of the upper probe module (200) are located on the same line and the upper transducer (220) generates an ultrasonic signal, the upper transducer (220) receives the ultrasonic signal reflected from each layer of the object (10), and the first receiving unit (122) of the lower probe module (100) receives the ultrasonic signal transmitted through the object (10), thereby enabling both reflection method and transmission method data for the object (10) to be obtained.

[0081] In addition, when the lower transducer (120) generates an ultrasonic signal, the lower transducer (120) receives the ultrasonic signal reflected from each layer of the object (10), and the second receiving unit (222) of the upper probe module (200) receives the ultrasonic signal transmitted through the object (10), thereby being able to obtain data of both the reflection method and the transmission method for the object (10).

[0082] According to an embodiment of the present invention, the trigger control unit (160) can enable the lower transducer (120) and the upper transducer (220) to generate ultrasonic waves alternately at a specified time difference.

[0083] Specifically, the lower transducer (120) and the upper transducer (220) can detect the object (10) above and below the object (10) by a point intersection method by alternately generating ultrasonic waves.

[0084] According to an embodiment of the present invention, the lower probe module (100) and the upper probe module (200) scan the object (10) while moving along the object (10), and when the lower probe module (100) and the upper probe module (200) move in a first direction, the trigger control unit (160) can cause the lower transducer (120) to generate ultrasonic waves.

[0085] Specifically, refer to Figure 5 , the lower probe module (100) and the upper probe module (200) are facing in a positive direction (a first direction, Figure 5 When the lower transducer (120) moves in the direction of the arrow in the figure, the trigger control unit (160) can detect the object (10) by causing the lower transducer (120) to generate ultrasonic waves.

[0086] Furthermore, when the lower probe module (100) and the upper probe module (200) move in the second direction, the trigger control unit (160) can cause the upper transducer (220) to generate ultrasonic waves.

[0087] Specifically, refer to Figure 5 , the lower probe module (100) and the upper probe module (200) are facing in opposite directions (second direction, Figure 5 When the upper transducer (220) moves in the opposite direction of the arrow in the figure, the trigger control unit (160) can detect the object (10) by causing the upper transducer (220) to generate ultrasonic waves.

[0088] That is, when the lower probe module (100) and the upper probe module (200) move in a forward direction, the object (10) can be detected by the lower transducer (120), and when the lower probe module (100) and the upper probe module (200) move in a reverse direction, the object (10) can be detected by the upper transducer (220).

[0089] According to an embodiment of the present invention, the first direction and the second direction may be opposite directions. Specifically, when the first direction is a positive direction, the second direction may be a negative direction.

[0090] However, the first direction may be a reverse direction, and the second direction may be a forward direction. That is, when the lower probe module (100) and the upper probe module (200) are facing the forward direction (the second direction, Figure 5 When the lower probe module (100) and the upper probe module (200) move in the opposite direction (the first direction, Figure 5 When the first direction and the second direction move in the opposite direction of the arrow in the middle (in the opposite direction), the object (10) can be detected by the lower transducer (120). In addition, the first direction and the second direction are not limited to being opposite directions to each other, and the first direction and the second direction can be set to different directions.

[0091] As described above, the ultrasonic detection device according to the embodiment of the present invention can detect the object (10) by causing the lower transducer (120) and the upper transducer (220) to generate ultrasonic waves in a line crossing method.

[0092] Reference Figure 3According to another embodiment of the present invention, when the central axis (121) of the lower transducer (120) of the lower probe module (100) and the central axis (221) of the upper transducer (220) of the upper probe module (200) are not located on the same line, the object (10) can also be detected using an ultrasonic reflection (Echo, Reflection) method.

[0093] Reference Figure 3 By making the central axes of the lower transducer (120) and the upper transducer (220) not be located on the same line, the ultrasonic signals generated by the lower transducer (120) and the upper transducer (220) can be prevented from interfering with each other.

[0094] As described above, by making the central axis (121) of the lower transducer (120) and the central axis (221) of the upper transducer (220) of the upper probe module (200) not be located on the same line, the lower transducer (120) and the upper transducer (220) can generate ultrasonic waves at the same time, thereby being able to detect the object (10).

[0095] According to an embodiment of the present invention, the lower probe module (100) may be equipped with a first receiving unit (122), and the first receiving unit (122) may receive the ultrasonic wave generated by the lower transducer (120) of the lower probe module (100). The upper probe module (200) may be equipped with a second receiving unit (222), and the second receiving unit (222) may receive the ultrasonic wave generated by the upper transducer (220) of the upper probe module (200).

[0096] The first receiving unit (122) can be arranged inside the lower transducer (120), or the first receiving unit (122) can be arranged outside the lower transducer (120). In addition, the first receiving unit (122) can be arranged inside the trigger control unit (160), or the first receiving unit (122) can be arranged outside the trigger control unit (160).

[0097] The second receiving unit (222) can be configured inside the upper transducer (220), or the second receiving unit (222) can also be configured outside the upper transducer (220). In addition, the second receiving unit (222) can be configured inside the trigger control unit (160), or the second receiving unit (222) can also be configured outside the trigger control unit (160).

[0098] The trigger control unit (160) can control the time point at which the lower transducer (120) generates an ultrasonic wave and the time point at which the upper transducer (220) generates an ultrasonic wave.

[0099] According to an embodiment of the present invention, when the central axis (121) of the lower transducer (120) and the central axis (221) of the upper transducer (220) of the upper probe module (200) are not located on the same line, the trigger control unit (160) can enable the lower transducer (120) and the upper transducer (220) to generate ultrasonic waves simultaneously.

[0100] Since the central axis (121) of the lower transducer (120) and the central axis (221) of the upper transducer (220) of the upper probe module (200) are not located on the same line, the ultrasonic waves generated by the lower transducer (120) and the upper transducer (220) may not interfere with each other. Therefore, the trigger control unit (160) can detect the object (10) by causing the lower transducer (120) and the upper transducer (220) to generate ultrasonic waves at the same time.

[0101] Furthermore, according to an embodiment of the present invention, the trigger control unit (160) can enable the lower transducer (120) and the upper transducer (220) to generate ultrasonic waves alternately at a specified time difference.

[0102] Specifically, the trigger control unit (160) can cause the upper transducer (220) to generate an ultrasonic wave after a specified time has passed since the lower transducer (120) was caused to generate an ultrasonic wave, or cause the lower transducer (120) to generate an ultrasonic wave after a specified time has passed since the upper transducer (220) was caused to generate an ultrasonic wave.

[0103] According to an embodiment of the present invention, the lower probe module (100) of the ultrasonic detection device using the upper probe module and the lower probe module may include a lower housing (110), a lower transducer (120), a lower water jacket (130), and a lower liquid injection unit (140).

[0104] The lower housing (110) may be a housing of the lower probe module (100). The lower housing (110) may be disposed below the object (10), the lower transducer (120) may be disposed on the lower housing (110), and the lower housing (110) may be connected to a mobile device and move in the x, y, and z directions.

[0105] According to an embodiment of the present invention, the position of the lower transducer (120) equipped on the lower housing (110) can be moved by moving the lower housing (110).

[0106] The lower transducer (120) is provided on the lower housing (110) and can generate ultrasonic waves to the object (10) or receive ultrasonic waves below the object (10). The lower transducer (120) is a device capable of generating ultrasonic waves, and ultrasonic waves can be irradiated below the object (10) through the lower transducer (120).

[0107] In addition, ultrasonic waves can also be received through the lower transducer (120). Specifically, the lower transducer (120) can also be used as a receiving unit and receive ultrasonic waves introduced into the lower transducer (120).

[0108] The lower water jacket (130) is provided with an internal space inside, into which one side of the lower transducer (120) can be inserted, and the internal space of the lower water jacket (130) can be filled with liquid.

[0109] If the ultrasonic wave generated by the lower transducer (120) is to be transmitted to the object (10), a transmission medium is required, and the transmission medium may be composed of a liquid. The inner space of the lower water jacket (130) may be filled with the transmission medium (composed of a liquid), and the transmission medium may be water. In the following, the transmission medium is described as water.

[0110] One side of the lower transducer (120) may be arranged in the inner space of the lower water jacket (130). The lower water jacket (130) may be equipped with a lower discharge unit (131), and the lower discharge unit (131) may be a through hole formed from the inside of the lower water jacket (130) toward the direction of the object (10).

[0111] According to an embodiment of the present invention, liquid can be sprayed toward an object through the lower water jacket (130) for detection without immersing the object in liquid (which is a transmission medium for transmitting ultrasonic waves). Specifically, liquid can be sprayed through the lower discharge unit (131) of the lower water jacket (130), and the sprayed liquid can be transmitted to the object (10) as a transmission medium.

[0112] The ultrasonic wave generated from the lower transducer (120) may be irradiated to the object (10) through the lower discharge unit (131). Figure 6 The water filling the inner space of the lower water jacket (130) is discharged together through the lower discharge unit (131) of the lower water jacket (130).

[0113] The water may be a transmission medium for transmitting ultrasonic waves, which is discharged through the lower discharge unit (131), and the ultrasonic waves generated from the lower transducer (120) may be irradiated to the object (10) through the water discharged by the lower discharge unit (131).

[0114] The water discharged through the lower discharge unit (131) may be moved to a water tank provided outside the lower housing (110), and the water moved to the water tank may be moved to the lower liquid injection unit (140) to be described later by a pump or the like.

[0115] Reference Figure 6 The lower liquid injection unit (140) can inject liquid into the inner space of the lower water jacket (130). The lower liquid injection unit (140) can be connected to a hose or the like extending to the outside, and the liquid can move to the lower liquid injection unit (140) through the hose.

[0116] The liquid moved to the lower liquid injection unit (140) moves to the inner space of the lower water jacket (130) through the lower liquid injection unit (140). The liquid injected into the inner space of the lower water jacket (130) through the lower liquid injection unit (140) may be water.

[0117] Reference Figure 6 , the lower liquid injection unit (140) according to an embodiment of the present invention includes a lower nozzle (141) and a lower bubble exhaust hole (150).

[0118] The lower nozzle (141) is connected to the inner space of the lower water jacket (130) and can be a nozzle through which liquid flows. The lower nozzle (141) is provided inside the lower liquid injection unit (140), and water can be injected into the lower water jacket (130) through the lower nozzle (141).

[0119] The lower bubble discharge hole (150) is connected to the lower nozzle (141). Specifically, the lower bubble discharge hole (150) may be a hollow tube provided above the lower nozzle (141), and one end of the lower bubble discharge hole (150) may be connected to the lower nozzle (141).

[0120] The lower bubble discharge hole (150) can be used to remove bubbles from the water flowing through the lower nozzle (141). The water flowing through the lower nozzle (141) is a transmission medium for transmitting the ultrasonic waves generated by the lower transducer (120). If bubbles are formed in the water stored in the lower nozzle (141), ultrasonic attenuation may occur due to the bubbles.

[0121] The lower bubble discharge hole (150) is used to prevent this phenomenon from occurring. The lower bubble discharge hole (150) may be provided above the lower nozzle (141), and bubbles may be removed from the water flowing through the lower nozzle (141) through the lower bubble discharge hole (150).

[0122] Specifically, when bubbles are generated in the water, the bubbles move to the upper part of the water. The water with bubbles can be discharged through the lower bubble discharge hole (150) provided above the lower nozzle (141), thereby removing the bubbles from the water passing through the lower nozzle (141).

[0123] The lower bubble discharge hole (150) includes a first bubble discharge hole (151) and a second bubble discharge hole (152). The first bubble discharge hole (151) is connected to the lower nozzle (141) and extends to the upper side of the lower nozzle (141). The first bubble discharge hole (151) can extend vertically from the upper side of the lower nozzle (141).

[0124] The second air bubble discharge hole (152) is communicated with the first air bubble discharge hole (151) and extends horizontally or obliquely downward from one end of the first air bubble discharge hole (151). Water can be discharged from the lower discharge unit (131) of the lower water jacket (130).

[0125] At this time, when the lower air bubble discharge hole (150) includes only the first air bubble discharge hole (151) extending vertically, water discharged from the lower discharge unit (131) is likely to be introduced into the lower air bubble discharge hole (150). When water is introduced into the lower air bubble discharge hole (150), it is difficult to remove air bubbles from the water moving to the lower liquid injection unit (140) through the lower air bubble discharge hole (150).

[0126] In order to prevent this, the second bubble discharge hole (152) extends horizontally or obliquely downward from one end of the first bubble discharge hole (151). Since the second bubble discharge hole (152) extends horizontally or obliquely downward from one end of the first bubble discharge hole (151), water discharged from the lower discharge unit (131) can be prevented from being introduced into the lower bubble discharge hole (150).

[0127] The lower nozzle (141) may be provided with a lower filter (142). The lower filter (142) may filter foreign matter present in the water flowing through the lower nozzle (141).

[0128] The lower nozzle (141) includes a lower micro nozzle unit (143), and the lower micro nozzle unit (143) is equipped with a plurality of micro tubes. The lower micro nozzle unit (143) is equipped with a plurality of micro tubes, and water flowing through the lower nozzle (141) passes through the lower micro nozzle unit (143).

[0129] The plurality of microtubes provided on the lower micronozzle unit (143) can extend in the same direction and in a direction parallel to the direction in which the lower nozzle (141) extends.

[0130] The lower micro nozzle unit (143) is used to form a laminar flow. When the water flowing through the lower nozzle (141) passes through the lower micro nozzle unit (143), the water flows through the lower micro nozzle unit (143) to form a laminar flow.

[0131] The water introduced into the inner space of the lower water jacket (130) by flowing through the lower nozzle (141) may be a transmission medium for transmitting the ultrasonic wave generated by the lower transducer (120).

[0132] When the water introduced into the inner space of the lower water jacket (130) through the lower nozzle (141) generates turbulent flow, it may be difficult for the lower transducer (120) to accurately irradiate the ultrasonic wave to a designated position of the object (10).

[0133] The lower micro-nozzle unit (143) is used to prevent this phenomenon from occurring. Water flowing through the lower nozzle (141) through the lower micro-nozzle unit (143) can form a laminar flow, thereby being able to accurately irradiate the ultrasonic wave generated from the lower transducer (120) to a designated position of the object (10).

[0134] A lower buffer space (144) may be provided between the lower nozzle (141) and the internal space of the lower water jacket (130) and the lower micro-nozzle unit (143), and the diameter of the lower buffer space (144) is greater than or the same as the diameter of the lower micro-nozzle unit (143).

[0135] Specifically, the water introduced into the lower nozzle (141) passes through the lower micro-nozzle unit (143) (on which a plurality of micro-tubes are provided), and then passes through the lower buffer space (144) (on which a plurality of micro-tubes are not provided) and is introduced into the interior of the lower water jacket (130).

[0136] The lower buffer space (144) can be used to prevent the water forming the laminar flow from mixing with each other. When the water passing through the lower micro nozzle unit (143) is directly introduced into the lower water jacket (130), the flow space of the water is expanded, thereby the water forming the laminar flow can mix with each other.

[0137] Furthermore, when the diameter of the connection point between the lower nozzle (141) and the inner space of the lower water jacket (130) is smaller than the diameter of the lower micro-nozzle unit (143), part of the water forming the laminar flow may collide with the side wall.

[0138] The lower buffer space (144) is used to prevent this phenomenon from occurring. The water passing through the lower micro nozzle unit (143) (on which a plurality of micro tubes are provided) is introduced into the interior of the lower water jacket (130) after passing through the lower buffer space (144) (on which a plurality of micro tubes are not provided), thereby preventing the water forming the laminar flow from mixing with each other.

[0139] In the above description, the lower bubble discharge hole (150) of the lower water jacket (130) and the lower liquid injection unit (140) are equipped with the lower filter (142), the lower micro-nozzle unit (143), and the lower buffer space (144), but may not be equipped with the lower bubble discharge hole (150), the lower filter (142), the lower micro-nozzle unit (143), and the lower buffer space (144) as needed.

[0140] The upper probe module (200) of the ultrasonic detection device using the upper probe module and the lower probe module according to an embodiment of the present invention comprises an upper shell (210), an upper transducer (220), an upper water jacket (230), and an upper liquid injection unit (240).

[0141] The upper housing (210) may be a housing of the upper probe module (200). The upper housing (210) may be arranged above the object (10), the upper transducer (220) may be arranged on the upper housing (210), and the upper housing (210) may be connected to a mobile device and move in the x, y, and z directions.

[0142] According to an embodiment of the present invention, the position of the upper transducer (220) equipped on the upper housing (210) can be moved by moving the upper housing (210).

[0143] The upper transducer (220) is provided on the upper housing (210) and can generate ultrasonic waves to the object (10) above the object (10). The upper transducer (220) can generate ultrasonic waves or receive ultrasonic waves. The upper transducer (220) is a device capable of generating ultrasonic waves, and ultrasonic waves can be irradiated above the object (10) through the upper transducer (220).

[0144] In addition, ultrasonic waves can also be received by the upper transducer (220). Specifically, the upper transducer (220) can also be used as a receiving unit and receive ultrasonic waves introduced into the upper transducer (220).

[0145] The interior of the upper water jacket (230) is provided with an internal space, into which one side of the upper transducer (220) can be inserted, and the internal space of the upper water jacket (230) can be filled with liquid.

[0146] If the ultrasonic wave generated by the upper transducer (220) is to be transmitted to the object (10), a transmission medium is required, and the transmission medium may be composed of a liquid. The internal space of the upper water jacket (230) may be filled with the transmission medium (composed of a liquid), and the transmission medium may be water. In the following, the transmission medium is described as water.

[0147] One side of the upper transducer (220) may be arranged in the inner space of the upper water jacket (230). The upper water jacket (230) may be equipped with an upper discharge unit (231), and the upper discharge unit (231) may be a through hole formed from the inside of the upper water jacket (230) toward the direction of the object (10).

[0148] According to an embodiment of the present invention, liquid can be sprayed toward an object through the upper water jacket (230) for detection without immersing the object in liquid (which is a transmission medium for transmitting ultrasonic waves). Specifically, liquid can be sprayed through the upper discharge unit (231) of the upper water jacket (230), and the sprayed liquid can be transmitted to the object (10) as a transmission medium.

[0149] The ultrasonic wave generated from the upper transducer (220) may be irradiated to the object (10) through the upper discharge unit (231). Figure 7 The water filling the internal space of the upper water jacket (230) is discharged together through the upper discharge unit (231) of the upper water jacket (230).

[0150] The water may be a transmission medium for transmitting ultrasonic waves, which is discharged through the upper discharge unit (231), and the ultrasonic waves generated from the upper transducer (220) may be irradiated to the object (10) through the water discharged by the upper discharge unit (231).

[0151] The water discharged through the upper discharge unit (231) may be moved to a water tank, and the water moved to the water tank may be moved to the upper liquid injection unit (240) to be described later by a pump or the like, and the water tank is provided outside the upper housing (210).

[0152] Reference Figure 7 The upper liquid injection unit (240) can inject liquid into the inner space of the upper water jacket (230). The upper liquid injection unit (240) can be connected to a hose or the like extending to the outside, and the liquid can move to the upper liquid injection unit (240) through the hose.

[0153] The liquid moved to the upper liquid injection unit (240) passes through the upper liquid injection unit (240) and moves to the inner space of the upper water jacket (230). The liquid injected into the inner space of the upper water jacket (230) through the upper liquid injection unit (240) may be water.

[0154] Reference Figure 7 , the upper liquid injection unit (240) according to an embodiment of the present invention includes an upper nozzle (241) and an upper bubble exhaust hole (250).

[0155] The upper nozzle (241) is connected to the inner space of the upper water jacket (230) and can be a nozzle through which liquid flows. The upper nozzle (241) is provided inside the upper liquid injection unit (240), and water can be injected into the upper water jacket (230) through the upper nozzle (241).

[0156] The upper bubble discharge hole (250) is provided on the upper water jacket (230), and the upper bubble discharge hole (250) extends from the inner space of the upper water jacket (230).

[0157] Specifically, the upper bubble discharge hole (250) may be a tube provided above the upper water jacket (230) and having a hollow interior, and one end of the upper bubble discharge hole (250) may be in communication with the upper water jacket (230).

[0158] The upper bubble discharge hole (250) is used to remove bubbles from the water stored in the internal space of the upper water jacket (230). The water stored in the upper water jacket (230) is a transmission medium for transmitting ultrasonic waves generated by the upper transducer (220). If bubbles are formed in the water stored in the upper water jacket (230), ultrasonic attenuation may occur due to the bubbles.

[0159] The upper air bubble discharge hole (250) is used to prevent this phenomenon from occurring, and the air bubbles stored in the water of the upper water jacket (230) can be removed through the upper air bubble discharge hole (250).

[0160] Specifically, when bubbles are generated in the water, the bubbles move to the upper part of the water. The water with bubbles can be discharged through the upper bubble discharge hole (250) provided above the upper nozzle (241), thereby removing the bubbles from the water passing through the upper nozzle (241).

[0161] The upper bubble discharge hole (250) may be provided above the upper water jacket (230), and water with bubbles formed therein may be removed from the water stored in the inner space of the upper water jacket (230) through the upper bubble discharge hole (250). The upper bubble discharge hole (250) may extend vertically from the upper portion of the upper water jacket (230).

[0162] In addition, the upper bubble discharge hole (250) may be connected to the upper nozzle (241). Specifically, the upper bubble discharge hole (250) may be a hollow tube provided above the upper nozzle (241), and one end of the upper bubble discharge hole (250) may be connected to the upper nozzle (241).

[0163] The upper bubble discharge hole (250) can be used to remove bubbles from the water flowing through the upper nozzle (241). The upper bubble discharge hole (250) can be provided above the upper nozzle (241), and water with bubbles formed can be removed from the water flowing through the upper nozzle (241) through the upper bubble discharge hole (250). The upper bubble discharge hole (250) can extend vertically from the upper nozzle (241) and communicate with the outside.

[0164] The upper nozzle (241) may be provided with an upper filter (242). The upper filter (242) may filter foreign matter present in the water flowing through the upper nozzle (241).

[0165] The upper nozzle (241) includes an upper micro-nozzle unit (243), and the upper micro-nozzle unit (243) is equipped with a plurality of micro-tubes. The upper micro-nozzle unit (243) is equipped with a plurality of micro-tubes, and water flowing through the upper nozzle (241) passes through the upper micro-nozzle unit (243).

[0166] The plurality of microtubes provided on the upper micronozzle unit (243) can extend in the same direction and in a direction parallel to the direction in which the upper nozzle (241) extends.

[0167] The upper micro-nozzle unit (243) is used to form a laminar flow. When water flowing through the upper nozzle (241) passes through the upper micro-nozzle unit (243), the water flows through the upper micro-nozzle unit (243) to form a laminar flow.

[0168] The water introduced into the inner space of the upper water jacket (230) by flowing through the upper nozzle (241) may be a transmission medium for transmitting the ultrasonic wave generated by the upper transducer (220).

[0169] When water introduced into the inner space of the upper water jacket (230) through the upper nozzle (241) generates turbulent flow, it may be difficult for the upper water jacket (230) to accurately irradiate ultrasonic waves to a designated position of the object (10).

[0170] The upper micro-nozzle unit (243) is used to prevent this phenomenon from occurring. Water flowing through the upper nozzle (241) through the upper micro-nozzle unit (243) can form a laminar flow, thereby being able to accurately irradiate the ultrasonic wave generated from the upper transducer (220) to a designated position of the object (10).

[0172] Specifically, the water introduced into the upper nozzle (241) passes through the upper micro-nozzle unit (243) (on which a plurality of micro-tubes are provided), and then passes through the upper buffer space (244) (on which a plurality of micro-tubes are not provided) and is introduced into the interior of the upper water jacket (230).

[0173] The upper buffer space (244) can be used to prevent the water forming the laminar flow from mixing with each other. When the water passing through the upper micro nozzle unit (243) is directly introduced into the upper water jacket (230), the flow space of the water is expanded, thereby the water forming the laminar flow can mix with each other.

[0176] In the above description, the upper bubble discharge hole (250) of the upper water jacket (230) and the upper liquid injection unit (240) are equipped with the upper filter (242), the upper micro-nozzle unit (243), and the upper buffer space (244), but may not be equipped with the upper bubble discharge hole (250), the upper filter (242), the upper micro-nozzle unit (243), and the upper buffer space (244) as needed.

[0177] Reference Figure 8 and Fig. 9 , the ultrasonic detection device using the upper probe module and the lower probe module according to an embodiment of the present invention further includes a liquid supply unit (300).

[0178] The liquid supply unit (300) may be connected to the lower liquid injection unit (140) or the upper liquid injection unit (240), and the liquid supply unit (300) may supply liquid to the lower liquid injection unit (140) or the upper liquid injection unit (240).

[0180] The liquid supply unit (300) according to an embodiment of the present invention includes a liquid storage tank (310), a liquid injection unit (320), a liquid discharge unit (330), and a bubble discharge hole (340).

[0181] Reference Figure 8 and Fig. 9 The liquid storage tank (310) is provided with a space for storing liquid therein. The liquid injection unit (320) injects liquid into the liquid storage tank (310), and the liquid can be stored in the liquid storage tank (310) through the liquid injection unit (320).

The liquid stored in the liquid storage tank (310) may be discharged through the liquid discharge unit (330), and the liquid discharged through the liquid discharge unit (330) may be supplied to the lower liquid injection unit (140) or the upper liquid injection unit (240).

[0188] However, as required, the liquid storage tank (310) and the liquid discharge unit (330) may not be provided with the filter (360), or the filter (360) may be provided in the liquid injection unit (320).

[0189] According to an embodiment of the present invention, the liquid stored in the liquid storage tank (310) may be water. The bubble discharge hole (340) extends from the top of the liquid storage tank (310). Specifically, the bubble discharge hole (340) may be a hollow tube provided above the liquid storage tank (310), and one end of the bubble discharge hole (340) may be in communication with the liquid storage tank (310).

[0190] The bubble discharge hole (340) is used to remove bubbles from the water stored in the internal space of the liquid storage tank (310). The water stored in the liquid storage tank (310) is a transmission medium for transmitting ultrasonic waves generated by the lower transducer (120) or the upper transducer (220). When bubbles are formed in the water stored in the liquid storage tank (310), ultrasonic attenuation may occur due to the bubbles.

[0191] The bubble discharge hole (340) is used to prevent this phenomenon from occurring, and bubbles can be removed through the bubble discharge hole (340) before water is supplied to the lower liquid injection unit (140) or the upper liquid injection unit (240).

[0192] Specifically, when bubbles are generated in the water, the bubbles move to the top of the water. The water with bubbles can be discharged through the bubble discharge hole (340) provided above the liquid storage tank (310), thereby removing the bubbles before supplying water to the lower liquid injection unit (140) or the upper liquid injection unit (240).

[0193] The bubble discharge hole (340) may be provided above the liquid storage tank (310), and bubbles can be removed from the water stored in the inner space of the liquid storage tank (310) through the bubble discharge hole (340). The bubble discharge hole (340) vertically extends from the top of the liquid storage tank (310).

[0194] Reference Fig. 9 The liquid storage tank (310) and the liquid discharge unit (330) may be provided with a filter (360). The filter (360) may filter foreign matter present in the water stored in the liquid storage tank (310) and the water flowing through the liquid discharge unit (330).

[0197] In addition, the ultrasonic detection device using the upper probe module and the lower probe module according to the embodiment of the present invention performs detection below and above the object through the upper probe module and the lower probe module, thereby being able to detect above and below the object without inverting and moving the object, thereby shortening the process time.

[0198] In addition, the ultrasonic detection device using the upper probe module and the lower probe module according to the embodiment of the present invention performs detection below and above the object through the upper probe module and the lower probe module, thereby being able to detect above and below the object without inverting and moving the object, thereby being able to be linked with signal processing data obtained by scanning above and below the object in the absence of position alignment tolerance.

[0199] Furthermore, the ultrasonic detection device using the upper and lower probe modules according to the embodiment of the present invention forms bubble discharge holes on the lower and upper probe modules to remove bubbles in water, thereby preventing ultrasonic attenuation due to bubbles.

[0200] The present invention is described in detail by taking the preferred embodiments as examples, but the present invention is not limited to the above embodiments, and various modifications can be provided without exceeding the scope of the present invention.
