Hereinafter, an embodiment of an inspection result display device, a manufacturing system, an inspection result display method, a manufacturing method, and a program will be described with reference to the drawings.
1 , a manufacturing system 2 for manufacturing glass 1 includes a manufacturing device 3 that executes the manufacturing of the glass 1, and a quality control device 4 that controls the quality of the manufactured glass 1. The manufacturing device 3 manufactures the glass 1 from, for example, glass raw materials or cullet. Alternatively, the manufacturing device 3 processes raw glass manufactured outside the manufacturing device 3 to manufacture the glass 1. The manufacturing system 2 sends the glass 1 manufactured by the manufacturing device 3 to the quality control device 4, and causes the quality control device 4 to perform quality inspection such as inspection of the glass 1.

The glass 1 is a product having a shape such as a plate or a tube. In this example, the glass 1 is plate-shaped glass 1a. The glass 1 may be sent one by one from the manufacturing device 3 to the quality control device 4, or a certain number of pieces of glass 1 may be sent to the quality control device 4 in a lump sum.

As shown in FIG. 2, the manufacturing device 3 includes one or more processing units 5 that process the edge surface of the glass 1. In this example, the processing units 5 include multiple processing units 5 that operate differently when manufacturing glass. In this example, two processing units 5 are provided, including a first processing unit 5a and a second processing unit 5b that use different processing methods. Of the four sides of the plate-shaped glass 1, the processing units 5 process two opposing sides 6a, 6b with the first processing unit 5a, and process the remaining two opposing sides 6c, 6d with the second processing unit 5b.

The processing unit 5 has multiple processing parts 7 each with a different processing mode. The processing parts 7 are, for example, grindstones 8 that polish the end faces of the glass 1. The first processing unit 5a in this example has two processing parts 7, one of which is the first processing part 7a and the other is the second processing part 7b in this example. The second processing unit 5b in this example has two processing parts 7, one of which is the third processing part 7c and the other is the fourth processing part 7d in this example.

As shown in FIG. 3, the grindstone 8 is rotatably mounted around a central axis 9, and multiple steps 10 extending around the circumference are formed along the axial direction (the Z-axis direction in the figure). The grindstone 8 uses the steps 10 to grind the edge of the glass 1. The steps 10 are formed in, for example, 30 to 50 steps. During grinding work, the position of the grindstone 8 is set in the axial direction, so that the steps 10 are appropriately used according to the grinding specifications.

As shown in FIG. 1, the quality control device 4 includes an inspection device 11 that inspects the quality of the manufactured glass 1, and an inspection result display device 12 that functions as a user interface that displays the inspection results of the inspection device 11. The inspection device 11 inspects the quality of the end face of the glass 1. Note that the inspection device 11 in this example inspects the quality of the plate glass 1a as the glass 1. Also, in this example, the inspection device 11 inspects the end face 13 (see FIG. 3) of the plate glass 1a.

The inspection device 11 includes an inspection control unit 14 that controls the operation of the inspection device 11, and an imaging unit 15 that images the manufactured glass 1. The inspection control unit 14 includes an image processing unit 16 that processes image data D1 captured by the imaging unit 15, and a judgment unit 17 that judges the quality of the glass 1 based on the image processed by the image processing unit 16. The image processing unit 16 converts the image data D1, which is the captured image, into a test image that can be judged by the judgment unit 17. The judgment unit 17 judges defective locations in the glass 1 based on the test image obtained by image processing.

The judgment method of the judgment unit 17 may be, for example, a method using AI (Artificial Intelligence). Examples of AI methods include machine learning, deep learning, convolutional neural networks, and reinforcement learning. The judgment unit 17 judges, for example, what kind of defect has occurred in what location in one sheet of glass 1a. In this example, the judgment unit 17 ranks the defects in the sheet of glass 1a. The ranks are, for example, five levels from A to E, with the degree of defect increasing relatively as the rank goes from A to E. The judgment unit 17 outputs the inspection result data Dk obtained by the judgment to the inspection result display device 12.

When judging defects in the glass 1, the inspection control unit 14 acquires equipment status data D2 relating to the current state of the manufacturing equipment 3 from the manufacturing equipment 3. The equipment status data D2 is a group of data relating to the work history performed by the manufacturing equipment 3 during glass manufacturing, and includes, for example, the number of stages of the grinding wheel 8 used for polishing and the processing distance of the grinding wheel 8. When the inspection control unit 14 outputs the inspection result data Dk to the inspection result display device 12, it also outputs image data D1 and equipment status data D2 related to this inspection result data Dk to the inspection result display device 12.

The inspection result display device 12 displays an inspection result display screen 18 on the display unit 19, which notifies the user of defects in the glass 1, based on the inspection result data Dk acquired from the inspection device 11. The inspection result display screen 18 is generated, for example, for each sheet of glass 1. Defects include, for example, "chipped," "scratched," "dented," and "surface roughness."

The test result display device 12 includes an input unit 20 that is used when operating the test result display device 12. The input unit 20 is, for example, a keyboard.
The inspection result display device 12 includes a memory 21 that stores the inspection result data Dk acquired from the inspection device 11. The memory 21 is, for example, a non-volatile memory such as a RAM or an EEPROM. When writing the inspection result data Dk, the memory 21 also writes and stores image data D1 and device current status data D2 associated with the inspection result data Dk.

The inspection result display device 12 is equipped with a display processing unit 22 that controls the display of the inspection result display screen 18 on the display unit 19. The display processing unit 22 displays the inspection result display screen 18, which notifies defective parts of the glass 1, on the display unit 19 based on the inspection result data Dk acquired from the inspection device 11. In this example, the display processing unit 22 generates the inspection result display screen 18 using the inspection result data Dk and the image data D1 and device current status data D2 associated therewith. The display processing unit 22 executes the program Dpr stored in the memory 21 to perform display processing of various screens on the display unit 19. In the case of plate glass 1a, the display processing unit 22 displays the inspection result display screen 18 relating to the inspection result of the end surface 13 of the plate glass 1a on the display unit 19.

As shown in FIG. 4, the inspection result display screen 18 includes a selection field 24 for items 23 to be displayed on the inspection result display screen 18. The items 23 include, for example, an inspection result rank selection item 23a for selecting a defect rank to be displayed as an inspection result, and a corner detail selection item 23b for selecting details of the corners of the sheet glass 1a.

The display processing unit 22 displays the inspection result display screen 18 according to the item 23 selected by the operator in a format in which the defective areas are associated with a glass image 25 that resembles the shape of the glass 1. The glass image 25 may be a photograph of the glass 1 or a copy or schematic representation of the glass 1. In this example, the inspection result display screen 18 includes an image display field 26 in which a list of images of the defective areas of the glass 1 is displayed, and the glass image 25 is displayed in the image display field 26. The glass image 25 is displayed at a size that fits the frame of the image display field 26. The glass image 25 is formed in a rectangular shape with chamfered corners.

The image display field 26 includes a defect image display field 28 which is a display area for the defect image 27. The defect image display field 28 is displayed superimposed on the glass image 25. If multiple defects are extracted when the inspection result display screen 18 is displayed, multiple defect images 27 are displayed. A scroll section 29 is displayed at the bottom of the image display field 26, which is operated to move the display position of the image display field 26 up, down, left, and right.

As shown in FIG. 5, the inspection result display screen 18 includes a captured image 30 of the glass 1 captured by the photographing unit 15 during the inspection. The inspection result display screen 18 includes detailed data 31 of the inspection result held by the inspection result data Dk. In this example, a set of the captured image 30 and the detailed data 31 is displayed as one defect image 27. The captured image 30 may be, for example, the image itself captured by the photographing unit 15, or an image after image processing by the image processing unit 16. The captured image 30 may be, for example, a defect image 27 extracted by defect judgment, as well as a corner image that is an image of a corner part of the plate glass 1a, a fixed image captured at a predetermined location regardless of the presence or absence of a defect, etc.

Detailed data 31 includes, for example, image type, size, occurrence position, occurrence location, class, and rank. The image type of detailed data 31 indicates, for example, the type of image, such as an inspection image, a corner image, or a fixed image. The size of detailed data 31 indicates, for example, the size of the defect. The occurrence position of detailed data 31 indicates, for example, which of the four sides the defect occurs on. The occurrence location of detailed data 31 indicates, for example, the detailed position (point) of the defect. The class of detailed data 31 indicates, for example, the result of the defect type determination by AI. The rank of detailed data 31 indicates, for example, the rank of the defect.

As shown in FIG. 7, the inspection result rank selection item 23a has check boxes 32 for ranks A to E, for example, and the check box 32 for the rank for which an image is to be displayed is checked. Multiple check boxes 32 can be selected. The corner details selection item 23b has a pull-down menu 33 for details of the corner image (corner image). The pull-down menu 33 has, for example, rank, edge, corner number, and surface. The rank pull-down menu 33 is operated, for example, when specifying a rank. The edge pull-down menu 33 is operated, for example, when selecting the edge of the corner. The corner number pull-down menu 33 is operated, for example, when selecting the corner number. The surface pull-down menu 33 is operated, for example, when specifying whether the image is to be displayed as seen from the front or back side of the glass 1.

In addition to the inspection result rank selection item 23a and corner detail selection item 23b, the items 23 include, for example, a fixed image detail selection item 23c and a defect type selection item 23d. The fixed image detail selection item 23c is used to select the type of fixed image to be displayed on the screen, for example, by a pull-down menu 34. The defect type selection item 23d is used to select the type of defect to be displayed on the screen, for example, by a pull-down menu 35.

The inspection result display screen 18 includes a glass information display 36 that notifies the user of detailed information about the glass 1. The glass information display 36 includes fields for displaying, for example, the glass ID, line name, and lot number of the inspected glass 1. The glass ID is a unique ID given to each glass 1. The line name is the name of the production line for the glass 1. The lot number is a number indicating the production unit of the glass 1. Normally, the inspection result of the last glass 1 sent is displayed, but it is also possible to display, for example, a pull-down menu to select the inspection result of the glass 1 from the previous glass 1 and display it on the inspection result display screen 18.

The inspection result display screen 18 includes a manufacturing equipment status display 37 that notifies the current status of the manufacturing equipment 3 during the manufacturing of the glass 1 that was the subject of the inspection. In this example, the manufacturing equipment status display 37 displays information related to the processing unit 5, and includes, for example, a first processing unit display field 37a and a second processing unit display field 37b. The first processing unit display field 37a displays the number of steps used during the glass manufacturing and the processing distance, which is the usage history of that number of steps, for each of the first processing unit 7a and the second processing unit 7b. The second processing unit display field 37b displays the number of steps used during the glass manufacturing and the processing distance, which is the usage history of that number of steps, for each of the third processing unit 7c and the fourth processing unit 7d.

The inspection result display screen 18 includes a defect total display 38 that notifies at least the total number of defects that have occurred on one sheet of glass 1a. In this example, the defect total display 38 displays the number of defects that have occurred on each side of the sheet of glass 1a and the total of these.

The inspection result display screen 18 displays, for example, an OK button 39, an update stop button 40, a setting button 41, and an inspection result summary button 42. The OK button 39 is operated when displaying the inspection results of the glass 1. The update stop button 40 is operated when stopping the update of the inspection results of the glass 1. The setting button 41 is operated when re-setting various details of the selection field 24. The inspection result summary button 42 is operated when displaying an inspection result summary screen 43 (see Figures 1 and 10) on the display unit 19, which summarizes the past inspection results of multiple pieces of glass 1.

Next, the operation of the test result display device 12 of this embodiment will be described.
6, when displaying the inspection results of glass 1 on display unit 19, inspection result display screen 18 is launched on display unit 19, and an item 23 for which the inspection results are to be displayed is selected from among items 23 in selection field 24. In the example shown in the figure, for inspection result rank selection item 23a, check boxes 32 for rank D and rank E are checked. For each item 23 other than inspection result rank selection item 23a, "ALL" is selected in pull-down menus 33 to 35.

As shown in FIG. 4, when the OK button 39 is operated after selecting an item 23, the display processing unit 22 displays the inspection result display screen 18 corresponding to the selected item 23 on the display unit 19. In this example, the display processing unit 22 displays the inspection result display screen 18 on the display unit 19 based on the inspection result data Dk, image data D1, and device current status data D2. The display processing unit 22 assigns numbers to locations on the edge of the glass image 25 where defects exist on the glass 1 that was inspected. The numbers indicate the serial number in the order in which the defects were detected.

In the example shown in the figure, the number "6" is added to the glass image 25 near the center of the screen in the horizontal direction in a location corresponding to side 6a, indicating that this is the sixth defect detected. In this way, it can be seen that there is one defect on side 6a of glass 1.

At the top of the screen in the vertical direction of the portion of glass image 25 that corresponds to side 6c, a "7" is added to indicate the seventh defect detected. Near the center of the screen in the vertical direction of the portion of glass image 25 that corresponds to side 6c, from the top of the screen, a "4" is added to indicate the fourth defect detected, a "2" is added to indicate the second defect detected, a "5" is added to indicate the fifth defect detected, and a "3" is added to indicate the third defect detected. In this way, it can be seen that there are a total of five defects on side 6c of glass 1.

In this example, numbers (in the example shown in the figure, "19," "20," "21," and "22") are also added to the locations in the glass image 25 that correspond to the four corners of the glass sheet 1a. This is because the system is preset to take corner images of the glass sheet 1a to check its quality, regardless of whether there are defects or not.

The defect image display area 28, which is displayed over the glass image 25, displays a defect image 27 relating to the detected defect. If multiple defects are detected, multiple defect images 27 are displayed on the screen. The defect images 27 are images that correspond to the numbers displayed on the glass image 25. In this example, the defect images 27 corresponding to the numbers "2" to "7" and "19" to "22" are displayed in a list in the defect image display area 28.

As shown in FIG. 5, the defect image 27 is displayed as a set of the captured image 30 and detailed data 31. Therefore, by checking the captured image 30, it is possible to visually confirm the shape of the defect. Furthermore, by checking the detailed data 31, it is possible to recognize the image type, size, occurrence position (side on which the defect occurs), occurrence location, class, and rank of the defect. In particular, the class column displays the defect judgment results made by AI, so it is possible to confirm the highly accurate judgment results made by AI in this column.

As shown in FIG. 8, the inspection result display screen 18 displays a manufacturing equipment current status display 37 that notifies the current state of the manufacturing equipment 3 at the time when the glass 1 to be inspected was manufactured. In the example shown in the figure, the current state of the first processing unit 5a is that the number of steps of the first processing section 7a is "1" and the processing distance is "100 (unit is arbitrary)", the number of steps of the second processing section 7b is "4" and the processing distance is "300 (unit is arbitrary)". The current state of the second processing unit 5b is that the number of steps of the third processing section 7c is "2" and the processing distance is "250 (unit is arbitrary)", and the number of steps of the fourth processing section 7d is "3" and the processing distance is "120 (unit is arbitrary).

As shown in FIG. 9, the inspection result display screen 18 displays a defect total display 38, which is the defect determination result for the glass 1 that was the subject of the inspection. In this example, the defect total display 38 displays the total number of defects for all ranks. In the example shown in the figure, for example, the number of defects on the first side 6a is "5", the number of defects on the second side 6b is "0", the number of defects on the third side 6c is "10", and the number of defects on the fourth side 6d is "4". It also shows that the total number of defects on the first to fourth sides is "19".

As shown in FIG. 10, when the inspection result tally button 42 on the inspection result display screen 18 is operated, the display processing unit 22 displays on the display unit 19 an inspection result tally screen 43 that tallys up the tallying results of multiple pieces of glass 1 in the past. At this time, the display processing unit 22 displays on the display unit 19 the inspection result tally screen 43 in place of the inspection result display screen 18. It is preferable that the number of pieces of glass 1 to be counted is, for example, about 50 pieces.

The inspection result summary screen 43 includes a unit-by-unit summary display 44 that sums up the history of the number of defects in each piece of glass over the past several sheets for each processing unit 5. In this example, the unit-by-unit summary display 44 includes, for example, a first processing unit history display field 45 that displays the history of the number of defects that occurred when the first processing unit 5a was used, and a second processing unit history display field 46 that displays the history of the number of defects that occurred when the second processing unit 5b was used. The unit-by-unit summary display 44 in this example picks up and displays the number of defects for each stage of the processing section 7 over the past several sheets.

Specifically, the first processing unit history display field 45 includes a tally graph 45a that displays the number of defects in the number of stages of the processing section 7 selected in the pull-down menu 45b for selecting the number of stages as a bar graph for the past several sheets. The first processing unit 5a polishes the edges 6a and 6c of the sheet glass 1a. Therefore, the tally graph 45a displays the number of defects in different colors for each edge 6a and 6c of the sheet glass 1a. Note that the tally graph 45a in FIG. 10 is a graph that displays the number of defects as a bar graph for the past 50 sheets. The first processing unit history display field 45 includes a pull-down menu 45c for setting the standard number of defects. If there is a bar graph with a number of defects exceeding the standard, the operator is notified of that number of sheet glass 1a, for example, in a visual or auditory form.

The second processing unit history display field 46 includes a tally graph 46a that displays the number of defects in the number of stages of the processing section 7 selected in the pull-down menu 46b for selecting the number of stages as a bar graph over the past several sheets. The second processing unit 5b polishes the sides 6b and 6d of the sheet glass 1a. Therefore, the tally graph 46a displays the number of defects in each of the sides 6b and 6d of the sheet glass 1a in different colors. Note that the tally graph 46a in FIG. 10 is a graph that displays the number of defects in a bar graph over the past 50 sheets. The second processing unit history display field 46 includes a pull-down menu 46c that sets the standard number of defects. If there is a bar graph with a number of defects above the standard, the operator is notified of the number of sheet glass 1a represented by the bar graph, for example, visually or audibly.

The inspection result summary screen 43 includes a color-coded summary display 47 that displays the number of defects in the past several pieces of glass sheet 1a in a graph for each piece and notifies the operator by color-coding each side of the glass sheet 1a. In this example, the color-coded summary display 47 includes a summary graph 47a that displays the number of defects in the past several pieces of glass sheet 1a as a group of bar graphs that are color-coded for each side. Note that the summary graph 47a in FIG. 10 is a graph that displays the number of defects in the past 50 pieces of glass sheet in a bar graph. The inspection result summary screen 43 includes a pull-down menu 47b that sets the standard number of defects. If there is a bar graph with a number of defects above the standard, the operator is notified visually or audibly of the number of pieces of glass sheet 1a represented by the bar graph.

The inspection result summary screen 43 includes an edge summary display 48 that displays the number of defects in the past multiple pieces of glass sheet 1a, tallied by edge. In this example, the edge summary display 48 displays the total number of defects by edge in a bar graph. In this example, the edge summary display includes a first edge summary display 48a that displays the defect count history for edge 6a of glass sheet 1a, a second edge summary display 48b that displays the defect count history for edge 6b of glass sheet 1a, a third edge summary display 48c that displays the defect count history for edge 6c of glass sheet 1a, and a fourth edge summary display 48d that displays the defect count history for edge 6d of glass sheet 1a.

The inspection result summary screen 43 includes a manufacturing equipment status display 49 similar to the manufacturing equipment status display 37 displayed on the inspection result display screen 18. Note that the manufacturing equipment status display 49 shown in the figure uses a different frame display method than the manufacturing equipment status display 37, but the content notified is the same. In addition, the manufacturing equipment status display 49 displays the processing distance of the processing unit 7 separately for the outbound and inbound processing. This allows the worker to recognize the processing distance of the processing unit 7 in more detail.

According to the test result display device 12 of the above embodiment, the following effects can be obtained.
(1) In the inspection result display device 12, the display processing unit 22 acquires the inspection result data Dk from the inspection device 11 that inspects the quality of the glass piece 1, and displays, on the display unit 19, the inspection result display screen 18 that notifies the user of defects in the glass piece 1 based on the inspection result data Dk. The display processing unit 22 displays the inspection result display screen 18 on the display unit 19 in a format in which the defective parts are associated with a glass image 25 that resembles the shape of the glass piece 1.

According to the configuration of the present disclosure, when the inspection results for glass defects are displayed on the display unit 19, the inspection result display screen 18 is displayed on the display unit 19. At this time, the defective areas are associated with a glass image 25 that represents the shape of the glass 1 and displayed on the inspection result display screen 18. Therefore, the inspection results for glass quality can be notified to the worker in an easy-to-understand manner.

(2) The inspection result display screen 18 includes a captured image 30 of the glass 1 captured by the imaging unit 15 of the inspection device 11 during the inspection. With this configuration, the captured image 30 displayed on the inspection result display screen 18 allows the shape of the defect that has occurred in the glass 1 to be directly confirmed.

(3) Each captured image 30 is displayed together with detailed data 31 of the inspection result contained in the inspection result data Dk. With this configuration, the shape of the defect can be ascertained from the captured image 30, and the location and rank of the defect can be ascertained from the detailed data 31. This is therefore more advantageous in notifying the operator of the glass quality inspection results in an easy-to-understand manner.

(4) The captured image 30 of the glass 1 is displayed superimposed on the glass image 25. With this configuration, the defective area and the glass image 25 can be efficiently displayed on the screen of the display unit 19.

(5) The glass 1 is a plate-shaped glass 1a. The inspection device 11 inspects the quality of the end surface of the plate-shaped glass 1a. The display processing unit 22 displays an inspection result display screen 18 related to the inspection results of the end surface of the plate-shaped glass 1a on the display unit 19. With this configuration, the inspection results targeting defects on the end surface of the plate-shaped glass 1a can be notified to the worker in an easy-to-understand manner.

(6) The display unit 19 displays the inspection result display screen 18 according to the item 23 selected by the worker. In this case, the item 23 that the worker wants to check can be appropriately displayed on the inspection result display screen 18, allowing the quality of the glass 1 to be checked with precision.

(7) The item 23 selected by the worker includes at least the rank of the defect. With this configuration, among the multiple defects that have occurred in the glass, the defects to be displayed on the screen can be appropriately selected according to the rank.

(8) The inspection result display screen 18 includes a selection field 24 for the items 23. This configuration makes it possible to appropriately select the content to be displayed on the inspection result display screen 18, and therefore allows the worker to appropriately select the items 23 that he or she wishes to check and display them on the inspection result display screen 18. This is therefore even more advantageous in notifying the worker of the glass quality inspection results in an easy-to-understand manner.

(9) The inspection result display screen 18 includes a defect total display 38 that notifies at least the total number of defects that have occurred in one piece of glass 1. This configuration makes it possible to grasp the total number of defects that have occurred in the glass 1, so that the quality of the glass can be easily determined.

(10) The display processing unit 22 displays an inspection result summary screen 43 on the display unit 19, which summarizes the past inspection results of multiple pieces of glass 1. With this configuration, by checking the inspection result summary screen 43, it is possible to grasp the trends in the results occurring in the glass 1. This makes it possible to take measures such as appropriately adjusting the manufacturing device 3 for the glass 1, thereby contributing to improving the quality of the glass 1.

The inspection result summary screen 43 includes a color-coded summary display 47 that displays the number of defects in each piece of glass 1a as glass 1 over multiple pieces of glass in the past in a graph, and notifies the user by color-coding each side of the glass 1a. This configuration makes it possible to determine which piece of glass 1 has the most defects and which of the four sides of the glass 1a has the most defects. In this way, it is possible to determine the tendency for defects to occur in the glass 1a, making it possible to take appropriate measures, such as adjusting the manufacturing device 3 as appropriate. This contributes to improving the quality of the glass 1.

(13) The inspection result summary screen 43 includes an edge-by-side summary display 48 that shows the number of defects in the glass sheet 1a as the glass 1 over the past several pieces of glass 1, tallied by edge. This configuration makes it possible to determine which of the four edges of the glass sheet 1a is likely to have defects when processed. In this way, it is possible to determine the tendency for defects to occur in the glass sheet 1a, making it possible to take appropriate measures, such as adjusting the manufacturing device 3 as appropriate. This contributes to improving the quality of the glass 1.
