Description

[Technical field]

[0001] The present invention relates to a display method, an inspection data processing device, and a program. [Background technology]

[0002] There are devices that display the results of inspection by a sensor such as an ultrasonic inspection device as an image. For example, Patent Document 1 discloses a technology for displaying a probe mark indicating the probing position and direction of an ultrasonic probe in correspondence with the display direction of an image in an inspection device capable of displaying the inspection results. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 4-166141 Summary of the Invention [Problem to be solved by the invention]

[0004] When an inspection is performed using a line sensor in such an inspection device, the inspection target area is read by the line sensor while the inspection target is moved relative to the line sensor in a certain direction. This results in the reading result being obtained. A scanned image based on the obtained inspection result is then generated and displayed on a display device used by the inspector.

[0005] Here, depending on whether the object to be inspected is moved relative to the line sensor in a first direction or a second direction, the inspection may be performed from a first end of the area to be inspected or from a second end opposite the first end. The reading results are drawn sequentially from the first horizontal end of the display area of ​​the display screen, so the orientation in which the scanned image is displayed in the horizontal direction differs depending on whether the inspection was performed from the first direction or the second direction. For this reason, when an inspector or the like visually checks an inspection target area of ​​an actual inspection target while looking at a scanned image, the horizontal orientation of the scanned image displayed on the display screen may not match the horizontal orientation of the inspection target as viewed during visual checking, making it difficult to intuitively grasp the correspondence between the appearance of the scanned image and the appearance of the actual inspection target.

[0006] The present invention has been made in consideration of the above-mentioned circumstances, and its purpose is to provide a display method, an inspection data processing device, and a program that can align the correspondence between the appearance of a scanned image and the appearance of an inspection object to be visually confirmed. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, one aspect of the present invention is a display method in which an object to be inspected is moved relative to a sensor along a scanning direction to obtain reading results obtained by reading the object to be inspected by the sensor in a reading order, and a determination is made based on the scanning direction as to which end in a display area the reading results should be arranged in accordance with the reading order from either a first end determined based on the scanning direction or a second end different from the first end.

[0008] In order to solve the above-mentioned problems, one aspect of the present invention is an inspection data processing device having an acquisition unit that acquires, from a sensor, reading results obtained by reading the inspection object by the sensor in a reading order by moving the inspection object relative to the sensor along a scanning direction, and a determination unit that determines, based on the scanning direction, from which end in a display area the reading results should be arranged in accordance with the reading order, between a first end determined based on the scanning direction and a second end different from the first end.

[0009] In order to solve the above-mentioned problems, one aspect of the present invention is a program that causes a computer to execute the steps of: moving an object to be inspected relative to a sensor along a scanning direction, thereby acquiring from the sensor a reading result obtained by reading the object to be inspected by the sensor in a reading order; and determining, based on the scanning direction, from which end in a display area the reading results should be arranged in accordance with the reading order, between a first end determined based on the scanning direction and a second end different from the first end. Effect of the Invention

[0010] According to the present invention, it is possible to match the correspondence between the appearance of the scanned image and the appearance of the inspection object to be visually confirmed. [Brief description of the drawings]

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0013] (About Inspection System 1) 1A is a schematic diagram showing an example of the configuration of an inspection system 1 in an embodiment. The inspection system 1 includes an inspection data processing device 10, an inspection device 20, and a conveying device 30. The inspection system 1 inspects an object 40 to be inspected.

[0014] The conveying device 30 conveys the inspection object 40 along a conveying direction. The conveying device 30 is, for example, a belt conveyor. The conveying device 30 conveys the inspection object 40 placed on the belt.

[0015] The inspection object 40 is an object to be inspected by the inspection device 20. The inspection object 40 is, for example, a packaging container. The inspection object 40 has a storage section in which a space for storing contents is formed on the inner periphery side by folding a sheet member and joining the periphery. 1A, the sheet member is folded in a width direction perpendicular to the longitudinal direction of the sheet member pulled out from one end of the wound roll so that a first end Tb1 and a second end Tb2 different from the first end Tb1 face each other. Then, the folded sheet member is joined at a preset width at the leading end side in the traveling direction in the conveying direction and at a trailing end side spaced a predetermined distance from the leading end side. Then, the sheet member is cut out as a bag-shaped sheet member having an opening. At this stage, since the sheet member is formed into a bag shape, the contents are filled into the storage portion formed on the inner periphery side of the sheet member through the opening by a filling device. After the contents are filled, the opening is joined by a joining device.

[0016] Such an inspection object 40 is transported by a transport device in a standing state in which the seal portion 41 is vertically above and the storage portion 42 is vertically below the seal portion 41. The inspection object 40 is transported so that the longitudinal direction of the inspection target area is along the transport direction. Although the inspection object 40 is formed into a bag shape by folding one sheet and joining the first end Tb1 and the second end Tb2 of the sheet, it is not necessary to fold one sheet. For example, the inspection object 40 may be obtained by overlapping two sheets and joining the peripheral portions of the two sheets facing each other.

[0017] The inspection device 20 is an ultrasonic inspection device equipped with an array sensor 20A. FIG. 1B is a cross-sectional view that diagrammatically illustrates the relationship between the array sensor 20A and an object 40 to be inspected. The array sensor 20A includes an irradiating unit 20Sa and a receiving unit 20Sb. The irradiating unit 20Sa includes a plurality of irradiating elements 20Sa1. The plurality of irradiating elements 20Sa1 are arranged so as to line up in a linear direction (arrangement direction). The receiving unit 20Sb includes a plurality of receiving elements 20Sb1. The plurality of receiving elements 20Sb1 are arranged so as to line up in a linear direction. The irradiation unit 20Sa and the receiving unit 20Sb are arranged to face each other, and are arranged so that ultrasonic waves irradiated from each irradiation element 20Sa1 of the irradiation unit 20Sa are received by the opposing receiving element 20Sb1 of each receiving element 20Sb1 of the receiving unit 20Sb. A joint portion (seal portion 41 described later) of the inspection object 40 passes between the irradiation unit 20Sa and the receiving unit 20Sb. The joint portion is, for example, a portion where the regions to be joined of the first end portion Tb1 and the second end portion Tb2 are joined. When the inspection object 40 is transported to pass such a joint portion, the direct wave of the ultrasonic wave irradiated from the irradiation unit 20Sa, the diffracted wave diffracted so as to go around the end portion of the inspection object 40, the transmitted wave that has passed through the joint portion, etc. are received by the receiving unit 20Sb. The array sensor 20A transmits information indicating the intensity of the ultrasonic wave received by the receiving unit 20Sb to the inspection data processing device 10 as a reading result. Here, in the receiving unit 20Sb, since multiple receiving elements 20Sb1 are arranged in a linear direction, the reading results obtained from each receiving element 20Sb1 according to one reading timing can be output as one line's worth of reading results. Hereinafter, one line's worth of reading results may be referred to as line data.

[0018] Returning to FIG. 1A, the inspection data processing device 10 is communicatively connected to the inspection device 20. The inspection data processing device 10 and the inspection device 20 may be connected wirelessly or by wire, or at least part of them may be wireless. The inspection data processing device 10 receives the read result transmitted from the array sensor 20A of the inspection device 20, generates a scan image according to the received read result, and outputs it to a display screen. Here, the inspection data processing device 10 has a liquid crystal display device, and may output the scan image by displaying the scan image on the display screen of the liquid crystal display device provided in the inspection data processing device 10. Also, the inspection data processing device 10 may transmit the scan image to an external display device and display it on the external display device. The display screen of the inspection data processing device 10 is disposed on an extension line of the viewing position of an observer (e.g., inspector U) and the position of the inspection object 40. The display screen of the inspection data processing device 10 is also disposed to face the observer. This allows the inspector U to perform a visual inspection by visually observing, from a predetermined viewing position where the inspection is performed, the appearance of the actual inspection object 40 and the appearance of the scanned image displayed on the display screen of the inspection data processing device 10 while comparing them.

[0019] FIG. 1C is a diagram showing a schematic diagram of the array sensor 20A scanning an inspection target 40. As shown in FIG. The inspection object 40 has a seal portion 41 and a storage portion 42. The seal portion 41 is a joining portion where the areas of the sheet members to be joined are joined. The seal portion 41 is also a portion where the opening is joined by a joining device after the contents are filled from the opening. Some parts of the periphery of the inspection object 40 are also joined other than the opening. In this embodiment, a case will be described where the part where the opening is joined is inspected as the inspection target area Rt, but other joint parts may also be inspected as the inspection target area.

[0020] The inspection object 40 moves relative to the inspection device 20 by being transported by the transport device 30. The transport direction in which the inspection object 40 is transported is a direction perpendicular to the longitudinal direction of the array sensor 20A of the inspection device 20. The longitudinal direction of the array sensor 20A is the direction in which the irradiation elements 20Sa1 and the receiving elements 20Sb1 are respectively arranged. In the example of this figure, the arrangement direction corresponds to the Y-axis direction, and the transport direction corresponds to the X-axis direction perpendicular to the arrangement direction (Y-axis direction). Moreover, the longitudinal direction of the seal portion 41 corresponds to the X-axis direction, and the lateral direction corresponds to the Y-axis direction. The length in the arrangement direction of the array sensor 20A (the length from one end to the other end of the irradiating elements 20Sa1 and receiving elements 20Sb1 arranged in the arrangement direction) is set to be approximately the same as the length in the width direction of the sealing portion 41 (the short side direction of the sealing portion 41) or longer than the width of the sealing portion 41. However, the length in the arrangement direction of the array sensor 20A may be set to various lengths depending on the purpose of the inspection. For example, the length in the arrangement direction of the array sensor 20A may be set to be shorter than the length in the width direction of the sealing portion 41.

[0021] In the following description, the direction in which the inspection object 40 is conveyed relative to the array sensor 20A is referred to as the scanning direction. In FIG. When the inspection object 40 is transported in the scanning direction (the direction indicated by the arrow D), the seal portion 41 passes between the irradiation portion and the receiving portion of the array sensor 20A. At this time, the array sensor 20A sequentially obtains the reading results for one line from the first end RE to the second end LE of the inspection object 40, and sequentially transmits the reading results for one line to the inspection data processing device 10 in the order in which the reading results are obtained.

[0022] (Regarding the test data processing device 10) Next, the test data processing device 10 will be described with reference to FIG. 2 is a block diagram showing a configuration of an inspection data processing device 10 according to an embodiment. The inspection data processing device 10 includes an acquisition unit 11, a direction determination unit 12, a section determination unit 13, a display control unit 14, an output unit 15, an input unit 16, a storage unit 17, and a control unit 18.

[0023] The acquiring unit 11 acquires various types of information. The acquiring unit 11 includes a read result acquiring unit 111 and a direction data acquiring unit 112. The read result acquiring unit 111 acquires the read result (line data) output from the inspection device 20. More specifically, the read result acquiring unit 111 acquires, from the array sensor 20A, the read result obtained by reading the inspection object 40 by the array sensor 20A in accordance with the reading order in response to the inspection object being moved relatively in the scan direction with respect to the array sensor 20A. The read result acquisition unit 111 writes the acquired line data in the storage unit 17 to store it.

[0024] The direction data acquisition unit 112 acquires direction data, which is information specifying the scan direction. The direction data acquisition unit 112 writes the acquired direction data in the storage unit 17 to store it. There are several methods for the direction data acquisition unit 112 to acquire direction data. For example, the direction data may be acquired by any of the following methods (1) to (3).

[0025] (1) How to accept operational input The direction data acquiring unit 112 acquires direction data based on the contents of an operation input to an input device. The input device may be, for example, at least one of a keyboard, a mouse, a touch panel, and the like. Such an input device may be provided in the test data processing device 10. Moreover, such an input device may be connected to the outside of the test data processing device 10. The direction data acquisition unit 112 may also acquire direction data by receiving the contents of an operation input to an electronic device (such as a display device, a smartphone, or a tablet) via a communication line. 3 is a diagram showing an example of a setting screen for inputting direction data. The control unit 18 may display such a setting screen on an electronic device (such as a display device, a smartphone, or a tablet) connected to the output unit 15 or the outside of the test data processing device 10.

[0026] This setting screen displays a message that is a character string of "Please input the scan direction", options for specifying the direction data, and a decision button. The operator selects and inputs an option from the options that corresponds to the positional relationship between the inspection device 20 and the transport device 30 that are actually installed and the direction in which the transport device 30 transports the inspection device 20 by operating the input device, and presses the decision button. As a method for specifying which option has been selected, for example, the radio button Bt may be pressed. The input device may be, for example, at least one of a keyboard, a mouse, a touch panel, and the like. The direction data acquisition unit 112 acquires the input content thus input as direction data. The operator may be an inspector U, or a person in charge of installation and maintenance of the transport device 30, the inspection device 20, the inspection data processing device 10, and the like. Here, the arrangement (layout) of the conveying device 30 and the inspection device 20 is determined according to the layout of an inspection room in a factory or the like where the inspection is performed. Then, the conveying device 30, the inspection device 20, etc. are installed according to the determined layout. Therefore, once the layout is determined, the scan direction is determined according to the layout. Once the layout of the conveying device 30 and the inspection device 20 is determined, the operator can check the setting screen while taking into account the conveying direction of the conveying device 30, and input direction data from the input device. Note that the determined layout is rarely changed frequently, but if it is changed, the direction data can be re-input.

[0027] (2) How to obtain a signal indicating the conveying direction Fig. 4A is a diagram for explaining a configuration for acquiring a signal indicating the conveying direction. As shown in Fig. 4A, the direction data acquiring unit 112 acquires direction data, for example, from the conveying device 30 or the inspection device 20. The conveying device 30 outputs a signal Y indicating the conveying direction via the inspection device 20 or directly to the inspection data processing device 10. For example, the signal Y may be a signal indicating the rotation direction of the rollers in the conveying device 30 or the traveling direction of the belt.

[0028] (3) How to obtain detection results from a detector Fig. 4B is a diagram for explaining a configuration for acquiring detection results from the detectors. As shown in Fig. 4B, in the inspection system 1, a passing detector SR1 is disposed on one side in the conveying direction of the conveying device 30 with the inspection device 20 as a reference, and SR2 is disposed on the opposite side to the one side. The passing detector SR1 detects whether the inspection object 40 has passed through, and outputs a signal Z1 indicating the result. The passing detector SR2 detects whether the inspection object 40 has passed through, and outputs a signal Z2 indicating the result. When a signal (signal Z1 or Z2) is obtained from either one of the passing detectors SR1 or SR2 and then it is detected that the inspection object 40 has been scanned by the inspection device 20, the directional data acquisition unit 112 acquires directional data based on whether signal Z1 or Z2 has been obtained. For example, when it is detected that the inspection object 40 has been scanned by the inspection device 20 after the signal Z1 is obtained from the passage detector SR1, the direction data acquisition unit 112 acquires direction data representing the direction D2. On the other hand, when it is detected that the inspection object 40 has been scanned by the inspection device 20 after the signal Z2 is obtained from the passage detector SR2, the direction data acquisition unit 112 acquires direction data representing the direction D1. Whether or not it has been detected that the inspection object 40 has been scanned may be determined based on whether or not an inspection section has been detected by the section determination section 13 described below. For example, when the inspection section has been detected by the section determination section 13, it may be detected that the inspection object 40 has been scanned, and when the inspection section has not been detected by the section determination section 13, it may be detected that the inspection object 40 has not been scanned. In this manner, the scanning direction can be determined based on the signal obtained from the passage detector SR1 or the passage detector SR2 and the fact that the inspection device 20 has detected that the inspection target 40 has been scanned. Here, the passing detector SR1 and the passing detector SR2 have been described as being arranged so as to sandwich the inspection device 20 therebetween, but as long as they are arranged at different positions along the conveying direction, they do not have to be positioned so as to sandwich the inspection device 20 therebetween.

[0029] 2, the direction determination unit 12 determines the scanning direction based on the direction data acquired by the direction data acquisition unit 112. The direction determination unit 12 may acquire the direction data directly from the direction data acquisition unit 112, or may acquire the direction data by reading out the direction data stored in the storage unit 116.

[0030] The section determination unit 13 detects the inspection section based on the result of determining whether the intensity of the received ultrasonic waves transmitted from the array sensor 20A is larger than a predetermined threshold. The inspection section is a section from the time when a first end of the inspection object 40 reaches the array sensor 20A to the time when a second end of the inspection object 40 finishes passing through the array sensor 20A. That is, the section determination unit 13 detects the inspection section by determining whether the inspection of the inspection object 40 has started and whether the inspection has ended.

[0031] FIG. 5 is a diagram for explaining the process performed by the section determination unit 13 in the embodiment. 5 shows the relationship between the intensity of ultrasonic waves received by any one of the receiving elements 20Sb1 of the receiving unit 20Sb and the measurement position in the sealing portion 41. The horizontal axis represents the measurement position, and the vertical axis represents the intensity of the received ultrasonic waves. The measurement position indicates the position in the transport direction of the sealing portion 41. As any one of the receiving elements 20Sb1, for example, the receiving element 20Sb1 arranged in the center in the arrangement direction of the receiving unit 20Sb may be used. The section determination unit 13 determines whether the inspection has started and whether the inspection has ended, for example, based on the intensity of the ultrasonic waves received by the receiving element 20Sb1 of the inspection device 20. For example, before the transported inspection object 40 reaches the array sensor 20A, that is, before the inspection starts, the ultrasonic waves irradiated from the irradiating unit 20Sa are directly received by the receiving unit 20Sb without being irradiated to the inspection object 40. In this case, the intensity of the received ultrasonic waves is approximately equal to the intensity of the irradiated ultrasonic waves (the section before the position p1). On the other hand, when the transported inspection object 40 reaches the array sensor 20A, ultrasonic waves are irradiated to the seal portion 41 of the inspection object 40, pass through the seal portion 41, and are received by the receiving portion. In this case, the ultrasonic waves that reach the seal portion 41 are attenuated when passing through the seal portion 41. Therefore, the intensity of the received ultrasonic waves is smaller than the intensity of the irradiated ultrasonic waves (near position p1).

[0032] Here, the section determination unit 13 stores a threshold value Th in advance. The section determination unit 13 determines whether the inspection has started or not and whether the inspection has ended or not by determining whether the intensity of the received ultrasonic wave is larger than the threshold value Th. For example, the section determination unit 13 determines that the inspection has started when the intensity of the received ultrasonic wave changes from a state exceeding the threshold value Th to a state equal to or smaller than the threshold value Th. On the other hand, the section determination unit 13 determines that the examination has ended when the intensity of the received ultrasonic wave changes from a state equal to or less than the threshold value Th to a state exceeding the threshold value Th. This enables the section determination unit 13 to detect the period from the time when the examination starts (position p1) to the time when the examination ends (position p2) as the examination section. In detecting the inspection section, the section determination unit 13 may use the detection result of any one of the receiving elements 20Sb1, or may use the detection results of a plurality of the receiving elements 20Sb1.

[0033] The section determination unit 13 may determine whether the inspection has started based on the intensity of the transmitted wave received by the inspection device 20, and may determine that the inspection has ended when a preset time has elapsed since it was determined that the inspection has started. The preset time may be determined based on the length of the seal portion 41 in the longitudinal direction and the conveying speed of the conveying device 30.

[0034] Furthermore, the section determination unit 13 may determine the start and end of the inspection based on, for example, the detection results of the passing detectors SR1 and SR2. The passing detectors SR1 and SR2 are disposed at different positions in the conveying direction conveyed by the conveying device 30, as in FIG. 4B. The section determination unit 13 determines that the inspection has started when either the passing detector SR1 or the passing detector SR2 detects that the inspection object 40 has arrived, and determines that the inspection has ended when the other passing detector 13 detects that the inspection object 40 has transitioned from a detected state to an undetected state.

[0035] Also, the section determination unit 13 may determine the start and end of the inspection based on, for example, a preset set time. In this case, for example, when the conveying speed of the conveying device 30 is a predetermined conveying speed and the inspection objects 40 placed on the conveying device 30 are placed at constant intervals, the start and end of the inspection arrive at a constant time interval. Such a set time is determined in advance based on the constant time. Then, when the inspection is started so that the count start timing of the set time coincides with the timing when a certain inspection object 40 reaches the array sensor 20A, the section determination unit 13 can detect the start and end of the inspection in order each time the set time arrives.

[0036] 2, the display control unit 14 generates a scan image based on the read result for each line obtained from the array sensor 20A. The read result from which the scan image is generated is, for example, a read result belonging to the inspection section identified by the section determination unit 13. The display control unit 14 determines, based on the scanning direction, from which end in the display area the reading results are to be arranged in accordance with the reading order: a first end determined based on the scanning direction, or a second end different from the first end.

[0037] The display control unit 14 acquires direction data, which is information specifying the scanning direction, and determines from which end of the display area, the first end or the second end, the read results are to be arranged according to the reading order, based on the acquired direction data. The display control unit 14 may acquire the direction data from the direction data acquisition unit 112, or may acquire the direction data by reading out the direction data stored in the storage unit 17.

[0038] Based on the determined result, the display control unit 14 generates a scan image by arranging the reading results (line data) for each line in order from either the first or second end of the display area, and causes the output unit 15 to display the generated scan image in the display area of ​​the display device.

[0039] The display control unit 14 stores a predetermined inspection reference value, judges whether the intensity of the received ultrasonic wave is larger or smaller than this reference value for each position of the seal portion 41, and generates a scan image in a different display mode according to the judgment result. Such a scan image is, for example, an image in which the intensity distribution of the ultrasonic wave is expressed by color. For example, the scan image may show inspection points in the line data where the intensity of the received ultrasonic waves is equal to or greater than Va in red (R), inspection points where the received intensity is equal to or greater than Vb but less than Va in green (G), and inspection points where the received intensity is less than Vb in blue (B). For example, in the seal portion 41, positions in the joint that satisfy the inspection criteria are shown in green (G), and positions that do not satisfy the inspection criteria are shown in blue (B). As a result, it is possible to generate and output scan images that can grasp the positions in the seal portion 41 that satisfy the inspection criteria and the positions that do not satisfy the inspection criteria. As a result, it is possible to grasp the inspection results based on the scan images. For example, in the inspection, the bonding state in the seal portion 41 is inspected. The bonding state can be peeled off, holes, scratches, foreign matter trapped, wrinkles, inappropriate seal width, double bonding, and the like. The inspection result can be obtained by determining the magnitude relationship between the intensity of the received ultrasonic waves and a threshold value for these bonding states, to determine whether or not the inspection criteria are satisfied. For example, for a position that satisfies the inspection criteria, a scan image can be output in which the bonding state is represented by a judgment result that the bonding state is "good", and when the inspection criteria is not satisfied, a scan image can be output in which the bonding state is represented by a judgment result that the bonding state is "bad".

[0040] Next, the correspondence between the appearance of the scanned image and the appearance of the inspection target to be visually confirmed will be described with reference to FIGS. 6 and 7. FIG. 6A and 6B are diagrams showing the relationship between the scanning direction and the reading order. In both of Figs. 6A and 6B, when these figures are viewed from the front, the first end RE of the inspection object 40 is on the right side and the second end LE is on the left side. In other words, the left and right orientations of the inspection object 40 in the horizontal direction are the same. In FIG. 6A, since the scanning direction is direction D1, when the inspection object 40 is conveyed toward the array sensor 20A, the second end LE, the central portion MD, and the first end RE of the inspection object 40 are scanned in this order. 6B, the scanning direction is direction D2, which is opposite to direction D1. Therefore, when the inspection object 40 is transported toward the array sensor 20A, the first end RE, the central portion MD, and the second end LE of the inspection object 40 are scanned in this order. In this way, even if the left and right orientations of the object to be inspected 40 in the horizontal direction are the same, if the transport direction is different, the order in which the object to be inspected 40 is read will differ depending on which end of the inspection area of ​​the object to be inspected 40 is read from.

[0041] Next, FIG. 7 is a diagram showing a case where a scanned image of the inspection target 40 scanned as shown in FIG. 6 is displayed on a display screen. In both Figures 7A and 7B, when viewed from the front, the first edge Ed1 of the display screen is on the left side and the second edge Ed2 is on the right side. That is, the left and right orientations in the horizontal direction of the display screen are the same. Also, both Figures 7A and 7B show a case where a scanned image is displayed such that the line data that is read first starts from the first edge Ed1 of the display screen, and the line data that is read later starts from the second edge Ed2.

[0042] FIG. 7A shows a case where a scan image GT10 is displayed on the display screen DS10 when the scanning direction is the direction D1 as shown in FIG. 6A. When the scanning direction is the direction D1, the display control unit 14 generates a scan image in which the line data of the second end LE is arranged at the first end Ed1 of the display screen, and the line data up to the first end RE is arranged in order to be lined up on the second end Ed2 side of the display screen according to the reading order. Therefore, if a seal defect E exists near the second end LE of the inspection target area as shown in FIG. 6A, the seal defect E is displayed as an image GE near the first end Ed1 of the display screen in the scan image GT10, which is displayed on the display screen DS10. In this case, the horizontal left-right orientation of the seal defect E is the same as the horizontal left-right orientation of the image GE on the display screen DS10. In this case, if an inspector views the inspection object 40 in the same way as when viewing FIG. 6A from the front, when the inspector views the scan image GT10 on the display screen DS10, the appearance of the inspection object being visually confirmed will match the appearance of the scan image GT10.

[0043] On the other hand, FIG. 7B shows a case where the scan image GT20 is displayed on the display screen DS20 when the scanning direction is the direction D2 as shown in FIG. 6B. Here, when the scanning direction is the direction D2, conventionally, the line data of the first end RE is arranged at the first end Ed1 of the display screen, and the line data up to the second end LE is arranged in order to be lined up on the second end Ed2 side of the display screen according to the reading order, to generate a scan image. In this case, if a seal defect E exists near the second end LE of the inspection target area as shown in FIG. 6B, the seal defect E is displayed as an image GE near the second end Ed2 of the display screen in the scan image GT20, which is displayed on the display screen DS20. In addition, in this case, the horizontal left-right orientation of the seal defect E is different from the horizontal left-right orientation of the image GE on the display screen DS20. In this case, if an inspector were to view the inspection object 40 in the same way as when viewing FIG. 6B from the front, when he or she views the scan image GT20 on the display screen, there would be no correspondence between the appearance of the inspection object being visually confirmed and the appearance of the scan image GT20.

[0044] In this way, if the appearance of the inspection target and the appearance of the scanned image do not match, it is difficult to grasp the correspondence when trying to confirm the defective part of the actual seal part 41 based on the image in the scanned image showing the inspection result that it is defective. This can make it difficult for the inspector to visually confirm.

[0045] In response to this, the display control unit 14 displays the scan image on the display screen so that the correspondence between the appearances of the scan image and the object to be visually confirmed by the inspector is consistent when the inspector visually checks the appearance of the scan image and the appearance of the object to be inspected. For example, when the scanning direction is direction D1, the display control unit 14 generates a scan image in which the line data at the second end LE is arranged at the first end Ed1 of the display screen, and the line data up to the first end RE is arranged in order to be lined up at the second end Ed2 side of the display screen according to the reading order. In this case, the scan image is displayed as shown in FIG. 7A. Furthermore, when the scanning direction is direction D2, the display control unit 14 generates a scan image in which the line data at the first end RE is arranged at the second end Ed2 of the display screen, and the line data up to the second end LE is arranged in order to be lined up at the first end Ed1 side of the display screen according to the reading order. In this case, the scan image is displayed as shown in Fig. 7A. Therefore, even if the scanning direction is direction D2 and the appearance of the inspection object 40 visually recognized by the inspector is as shown in Fig. 6B, it is possible to display the appearance of the inspection object 40 to be visually confirmed so that the correspondence between the appearance and the scan image is consistent. This allows the appearance of the inspection object to be matched with that of the scanned image regardless of the scanning direction. This makes it easy for the inspector to understand the correspondence between the appearance of the actual inspection object 40 and the appearance of the scanned image. This reduces the burden on the inspector in visual confirmation.

[0046] 2, the output unit 15 outputs the scanned image generated by the display control unit 14. When the output unit 15 includes a liquid crystal display provided in the test data processing device 10, the output unit may output the scanned image by rendering the scanned image on the liquid crystal display. The output unit 15 may display the scanned image on a display screen of the display device by outputting the scanned image to a display device connected to the outside of the test data processing device 10. The number of display devices to which the output unit 15 can output may be one or more.

[0047] The input unit 16 accepts input of various data. The input unit 16 may accept input of data based on operation contents input from an input device. The input device may be, for example, at least one of a keyboard, a mouse, a touch panel, and the like. Furthermore, the input unit 16 may be configured to receive input of various data output from another device, rather than from an input device.

[0048] The storage unit 17 stores various data, for example, various data acquired by the acquisition unit 11.

[0049] The control unit 18 controls each part of the test data processing device 10 .

[0050] (Flow of processing performed by the test data processing device 10) Next, the flow of processing performed by the test data processing device 10 will be described with reference to Fig. 8. Fig. 8 is a flowchart showing the flow of processing performed by the test data processing device 10. Here, as shown in Fig. 1, a case will be described in which an inspector U performs visual inspection at a predetermined viewing position where the inspection is carried out, and the display screen of the inspection data processing device 10 is disposed on an extension line of the viewing position and the position of the inspection object to be visually inspected. Also, the inspection object is sequentially transported in the transport direction by the transport device, and the inspector U performs visual inspection by visually checking the appearance of the inspection object 40 that arrives between the inspector's viewing position and the position where the display screen is provided, and the scanned image displayed on the display screen.

[0051] First, the direction data acquiring unit 112 of the inspection data processing device 10 acquires direction data (step S1) and stores it in the storage unit 17. Such direction data may be direction data accepted by any one of the above-mentioned methods (1) to (3). The transport device 30 transports the inspection object 40 to the array sensor 20A along the transport direction. Here, the inspection object 40 is transported to the array sensor 20A with the longitudinal direction of the inspection target area of ​​the inspection object 40 aligned with the transport direction. The transport direction is the above-mentioned direction D1 or direction D2. As the seal portion 41 of the inspection object 40 is transported between the irradiation unit 20Sa and the receiving unit 20Sb, the array sensor 20A sequentially generates line data according to the intensity of the ultrasonic waves received by the receiving unit 20Sb, and outputs the line data to the inspection data processing device 10. The read result acquisition unit 111 of the inspection data processing device 10 sequentially acquires the line data, and stores the acquired line data in the storage unit 17 (step S2).

[0052] Here, the section determination unit 13, for example, refers to the line data stored in the memory unit 17, detects the inspection section, and captures the line data belonging to the detected inspection section as the reading result for one inspection object 40. Here, when the inspection start position is detected, the section determination unit 13 captures the line data belonging to the inspection section until the inspection end position is detected.

[0053] Next, the control unit 18 of the test data processing device 10 judges whether or not the import of the read result has been completed (step S3). For example, when the section judgment unit 13 detects the test start position (position p1) and the test end position (position p2), it judges that the import of the read result has been completed (step S3-YES), and the process proceeds to step S4. On the other hand, if the control unit 18 detects the inspection start position but not the inspection end position, it determines that the import of the reading results has not been completed (step S3-NO) and transitions the processing to step S2, where it obtains the reading results and writes them to the memory unit 17.

[0054] When the acquisition of the read result is completed, the direction determination unit 12 of the test data processing device 10 determines whether or not the direction D1 shown in FIG. 6A is represented based on the direction data. The display control unit 14 determines whether or not to arrange the line data in order from the first end (eg, the first end Ed1) of the display area based on the result of the determination by the direction determination unit 12 and the scanning direction (step S4).

[0055] Here, when the direction data represents the direction D1, the display control unit 14 determines to arrange the line data in accordance with the reading order so that the line data are arranged in order from the first end Ed1 of the display area toward the second end Ed2 (step S4-YES). Then, the display control unit 14 generates a scan image in which the line data are arranged in order from the first end Ed1 (step S5). Here, for example, a scan image GT25 as shown in FIG. 9A is generated. That is, even when an inspector U1 visually recognizes the inspection object 40 and the scan image GT25, it is possible to match the appearance of the inspection object 40 with the appearance of the scan image GT25. When it is predetermined that the arrangement of line data in the display area starts from the first end Ed1, depending on the scanning direction (for example, in the case of direction D2), a scanned image cannot be generated until all line data belonging to one inspection section is stored in the storage unit 17. However, when it is determined whether the arrangement of line data starts from the first end Ed1 or the second end Ed2 depending on the scanning direction, it is not necessary to store all line data belonging to one inspection section in the storage unit 17. Therefore, it is possible to sequentially arrange line data in the display area every time it is obtained, without waiting for all line data belonging to one inspection section to be stored in the storage unit 17.

[0056] On the other hand, when the direction data indicates the direction D2, the display control unit 14 determines to arrange the line data in accordance with the reading order so that the line data are arranged in order from the second end Ed2 of the display area to the first end Ed1 side (step S4-NO), and generates a scan image in which the line data are arranged in order from the second end Ed2 (step S6). Here, even if the scanning direction is the direction D2, as shown in FIG. 9B, a scan image GT26 is generated in which the line data are arranged in accordance with the reading order so that the line data are arranged in order from the second end Ed2 of the display area. Therefore, as shown in the combination of FIG. 6B and FIG. 7B, the correspondence between the appearance of the inspection object 40 and the appearance of the scan image does not change. Therefore, as shown in FIG. 9B, even when an inspector U1 visually recognizes the inspection object 40 and the scan image GT26, it is possible to match the correspondence between the appearance of the inspection object 40 and the appearance of the scan image.

[0057] The output unit 15 outputs the scanned image generated by the display control unit 14 by displaying it on a display screen (step S7). In this manner, a scan image according to the scan direction is generated and the scan image is output, thereby making it possible to match the correspondence between the appearance of the inspection object 40 and the appearance of the scan image.

[0058] In the above embodiment, the case has been described where the display control unit 14 determines the order in which the line data is arranged according to the scanning direction. However, the order in which the line data is arranged may be determined taking into account not only the scanning direction but also other factors.

[0059] (Example 1) In the width direction, which is a direction perpendicular to the conveying direction of the conveying device 30, the appearance of the inspection object 40 differs depending on whether the inspector's viewing position is the first end side or the second end side opposite to the first end side. In other words, the surface that is visible when the inspector visually checks the inspection object 40 placed on the conveying device 30 is the front surface or the back surface of the inspection object 40. In such a case, the order in which the line data is arranged may be changed depending on whether the inspector is viewing the inspection object 40 and the display screen from the first end side (e.g., the left side) in the conveying direction or the second end side (e.g., the right side). In other words, if the back side of the inspection object 40 being conveyed is visible to the inspector, the scanned image may be displayed in a mode corresponding to the case where the back side is viewed.

[0060] Fig. 10 is a diagram for explaining a case where visual inspection is performed by an inspector. Fig. 10A is a diagram for explaining a case where the visual inspection position of inspector U1 is on the first end side (left side facing the conveying direction) in the width direction that is a direction perpendicular to the conveying direction of the conveying device 30. 10A, the inspection object 40 is transported and scanned along the direction D1, and is transported in a state where the surface of the inspection object 40 is visible from the viewing position of the inspector U1. In this case, the scan image generated, for example, by the above-mentioned step S5 or step S6 is output to the output unit 15 as is, without being flipped left and right in the horizontal direction. This allows the correspondence between the appearance of the inspection object 40 and the appearance of the scan image GT30 to be matched, as shown in FIG. 10A.

[0061] 10B is a diagram for explaining a case where the viewing position of inspector U2 is on the second end side (right side in the conveying direction) in the width direction, which is a direction perpendicular to the conveying direction of conveying device 30. In FIG. 10B, the inspection object 40 is conveyed and scanned along direction D1, and is conveyed with the back side of the inspection object 40 visible when viewed from the viewing position of inspector U2. In this case, the scan image generated in step S5 or step S6 described above is output to output unit 15 after being flipped left and right in the horizontal direction. This makes it possible to align the correspondence between the appearance of the object to be inspected 40 and the appearance of the scan image GT31, even if the viewing position of inspector U2 is on the opposite side of the conveying device 30 from the viewing position of inspector U1, as shown in Figure 10B. The inversion here refers to a process of swapping the left and right sides of the image so that the scanned image generated in step S5 or step S6 has line symmetry in the horizontal direction.

[0062] When displaying a scan image depending on whether the inspector's viewing position is the first end side or the second end side with respect to the transport device 30 as a reference, for example, viewing position information is stored in the memory unit 17. The viewing position information is information indicating whether the inspector's viewing position is the first end side or the second end side opposite to the first end side in the width direction that is a direction perpendicular to the transport direction of the transport device 30. Then, the display control unit 14 displays the scan image displayed in the display area based on the scan direction and the viewing position information so that the scan image corresponds to the appearance of the joint part of the inspection object 40 transported by the transport device 30. For example, after generating a scan image in step S5 or step S6, if the viewing position information is information representing the first end side, the display control unit 14 outputs the generated scan image as is. On the other hand, if the viewing position information is information representing the second end side, the display control unit 14 outputs the generated scan image with the left-right direction reversed.

[0063] Furthermore, when such visual recognition position information is used, it can be applied even when there are multiple display devices that display the scanned image.

[0064] FIG. 11 is a diagram showing an example of control data stored in memory unit 17. The control data in FIG. 11 is data in which display device identification information for identifying a display device is associated with viewing position information. The display device identification information is identification information for individually identifying a plurality of display devices. The number of display devices provided in one inspection line (a combination of one conveying device 30 and one array sensor 20A) in inspection system 1 may be one or multiple. Then, by storing the viewing position information of the inspector associated with each display device, it is possible to identify from which viewing position each display device is viewed. As a result, the display control unit 14 can identify the viewing position corresponding to the identification information of the display device to be displayed by referring to the viewing position information, and can decide whether or not to output the scanned image as is depending on the identified viewing position.

[0065] (Example 2) When an inspector views the inspection objects 40 transported by the transport device 30 at a viewing position, multiple inspection objects 40 are transported and scanned sequentially by the transport device 30 in a state where a predetermined surface (e.g., the front surface) is visible. However, in some cases, one or more inspection objects 40 may be transported by the transport device 30 and scanned with a surface (e.g., back surface) different from the normal surface being visible. In such a case, depending on the method of visual inspection, it may be possible to match the appearance of the actual inspection object 40 with the appearance of the scanned image by displaying the scanned image in a left-right inverted manner, rather than displaying the inspection results obtained by inspection with the back surface being visible as is. In such a case, it may be possible to detect whether the inspection object 40 transported by the transport device 30 is being transported with the front side or the back side visible, and depending on the detection result, it may be determined whether to output the scanned image as is or to output the scanned image with the left and right sides reversed. Methods for detecting whether the visible surface of the inspection object 40 transported by the transport device 30 is the front or back include (a) a method of imaging the inspection object 40 being transported, and (b) a method of using the relationship between the measurement position in the sealing portion 41 and the intensity of the received ultrasonic waves.

[0066] (a) A method for imaging an inspection object 40 being transported The inspection object 40 being transported by the transport device 30 is imaged from a viewing position by a camera. Then, based on the imaged image, it is detected whether the front side or the back side of the inspection object 40 is imaged. For example, the control unit 18 performs image processing on the imaged image to detect whether the imaged surface is the front side or the back side of the inspection object 40. For example, the feature amount of the image of the front side and the feature amount of the image of the back side are previously analyzed to obtain the feature amount of the front side and the feature amount of the back side. Then, the feature amount of the image of the inspection object 40 captured by the camera during the inspection may be obtained, and it may be determined whether the obtained feature amount matches with either the feature amount of the front side or the feature amount of the back side. Here, instead of determining whether the feature amounts match, it may be determined whether the degree of similarity of the feature amounts is equal to or higher than a certain level. The display control unit 14 may then acquire the result of this judgment, and determine whether to leave the placement method determined based on the scanning direction and the visual position information as is or change it depending on the acquired detection result.

[0067] (b) A method using the relationship between the measurement position and the intensity of the received ultrasonic waves Depending on the type of the inspection object 40, a singular point such as a punch hole or a notch may be formed in the seal portion 41. The intensity of ultrasonic waves received at a portion where such a singular point is provided is different from the intensity of ultrasonic waves received at a portion where no singular point is provided. Furthermore, the position where the singular point is provided may be a position that is asymmetric in the left-right direction, which is the conveying direction of the inspection object 40. That is, the singular point may be provided near a first end or near a second end in the left-right direction of the inspection object 40.

[0068] 12 is a diagram showing the relationship between the intensity of ultrasonic waves received by any one of the receiving elements 20Sb1 of the receiving unit 20Sb and the measurement position in the sealing unit 41 when a singular point is provided in the inspection target 40. The horizontal axis represents the measurement position, and the vertical axis represents the intensity of the received ultrasonic waves. The measurement position indicates the position in the transport direction of the sealing unit 41. As any one of the receiving elements 20Sb1, for example, the receiving element 20Sb1 arranged in the center in the arrangement direction of the receiving unit 20Sb may be used. 12 shows the intensity of ultrasonic waves received when an inspection object 40 having a punch hole as a singular point is scanned with its surface visible. The intensity of ultrasonic waves received at measurement position ps1, which corresponds to the position where the punch hole is provided, is greater than that in its vicinity. In this way, when the inspection object 40 is scanned with its surface visible, the intensity of ultrasonic waves received near measurement position ps1 is greater for each inspection object 40 than in its vicinity.

[0069] On the other hand, when any of the inspection objects 40 having such punch holes is scanned with the back side visible, the intensity of the ultrasonic waves received at measurement position ps2, which is a position different from measurement position ps1, is greater than that in its vicinity. In this case, the display control unit 14 stores in advance at which position (for example, measurement position ps1) a waveform corresponding to a singular point appears when the surface of the inspection target 40 is scanned. Then, based on the reading result acquired by the reading result acquisition unit 111, when the position where the singular point appears is the measurement position ps1, the display control unit 14 determines that the surface has been scanned, and decides to leave the arrangement method determined based on the scanning direction as it is.

[0070] On the other hand, based on the reading result acquired by the reading result acquisition unit 111, if the position where the singular point appears is not the measurement position ps1 (it is the measurement position ps2), the display control unit 14 determines that the back side has been scanned, and decides to output the layout method determined based on the scanning direction with the left and right reversed.

[0071] (Example 3) Also, the visual inspection may be performed while the inspection object 40 is being transported by the transport device 30, but may also be performed after the inspection object 40 is unloaded from the transport device 30 and is not being transported. More specifically, after the inspection object 40 is scanned by the inspection device 20, it may be unloaded from the transport device 30 and stored in a storage location. A display device may be installed in such a storage location, and a visual inspection may be performed while viewing the actual inspection object 40 in the stored state and the scanned image displayed on the display screen of the display device. In this way, even when visual inspection is performed at the storage location, the appearance of the stored inspection object 40 may be displayed so that the correspondence between the appearance of the inspection object 40 and the appearance of the scanned image is consistent depending on whether the inspection is performed by visually inspecting the front or back surface of the inspection object 40.

[0072] In the above-mentioned Example 1, the display control unit 14 determines whether or not to output the scanned image as is by referring to the visual recognition position information, but in Example 3, the display control unit 14 may determine whether or not to output the scanned image as is by referring to target surface information indicating whether the target surface of the inspection object visually inspected by the inspector is the first surface (e.g., the front surface) or the second surface (e.g., the back surface). Such target surface information may be stored in the storage unit 17 in advance. Fig. 13 is a diagram showing another example of control data stored in storage unit 17. The control data in Fig. 13 is data in which display device identification information for identifying a display device installed in a storage location is associated with target surface information. The target surface information is determined in advance and stored depending on whether a first surface (e.g., front surface) or a second surface (e.g., back surface) of inspection target object 40 is to be visually inspected while visually checking the display screen of the display device installed in the storage location. By referring to the target surface information, the display control unit 14 can specify whether a visual inspection is to be performed on the front side or the back side of the inspection target 40 at the storage location. Then, the display control unit 14 can determine whether or not to output the scanned image as is, depending on the specified target surface information.

[0073] In the above-described embodiment, the storage unit 17 of the inspection data processing device 10 is configured by a storage medium, such as a hard disk drive (HDD), a solid state drive (SSD), a flash memory, an electrically erasable programmable read only memory (EEPROM), a random access read / write memory (RAM), a read only memory (ROM), or any combination of these storage media. The storage unit of the inspection data processing device 10 may be, for example, a non-volatile memory.

[0074] In addition, the functional parts of the test data processing device 10 (acquisition part 11, direction determination part 12, section determination part 13, display control part 14, output part 15, input part 16, control part 18) are a CPU (Central Processing Unit) and may be realized by executing a program stored in a memory part provided in the test data processing device 10.

Alternatively, the inspection device 20 may be a device that obtains an image of the inspection target 40 and performs an inspection.
