Description

  The present invention relates to a visual inspection training device, a visual inspection training method, and a program for improving the detection power of visual inspection.

  In order to find a work defect occurring on the electronic circuit board, it is necessary to have the ability to instantly identify the defect. In the manufacturing industry, this production defect is eliminated, and production is performed while ensuring stable quality by automating the inspection process and manufacturing process management. However, the final inspection is only a visual inspection by personnel, and it is important to stabilize and equalize the inspection work.

  Visual inspection of an electronic circuit board takes several tens of seconds using a microscope or a magnifying glass while moving the visual field range for each visual field size. Because it is a manufacturing industry, it is not allowed to look at it slowly, and it is necessary to make a visual inspection within a certain time and to find out where the defect is. If a work defect is missed, it will be outflow failure.

  ISO9000 6.2.1 Human Resources / Generally, “Persons engaged in work that affects compliance with product requirements must be competent on the basis of education, training, skills and experience” Yes.

  This ability to detect work defects (hereinafter referred to as defect detection ability) is sometimes maintained at a high level by some workers or cultivated by long years of work history. If the defect detection ability does not improve even after gaining experience, the inspection quality may become unstable.

  In visual inspection, it is necessary to maintain the eyesight of the inspector. In order to compensate for the loss of visual acuity after long-term examinations, visual acuity recovery training is often performed. As a general vision recovery training, there is a vision recovery training using a plurality of targets such as a Landolt ring or Kana characters. For example, in Patent Document 1, since the orientation of the target of each display pattern used for visual acuity recovery training is changed after display to prevent the correct target from being memorized, training is always performed under correct optometry. There is disclosed a method for displaying a visual target for visual acuity measurement that can be performed.

  In Patent Document 2, the position of the figure group to be watched displayed on the screen of the image display, the discrete state of the figure group, the display color of the figure group, and the background color of the figure group constantly change, and the gaze of these figure groups is changed. Discloses a visual acuity training device that can simultaneously and easily train three types of muscles of the eye in a short period of time.

The visual inspection training device 1 includes an input unit 11, a display control unit 12, a storage unit 13, a timer unit 14, and a display unit 15.

  The input unit 11 receives an input of a start instruction and an end instruction for visual inspection training from the user. The input unit 11 sends the received visual inspection training start instruction and end instruction to the display control unit 12. The visual inspection training may be automatically started when the visual inspection training apparatus 1 is turned on, and the visual inspection training may be automatically ended when the power is turned off. In this case, the input unit 11 may not be provided.

  Upon receiving a start instruction from the input unit 11, the display control unit 12 reads the visual inspection training table from the storage unit 13, displays the visual inspection training table on the display unit 15, and starts the visual inspection training. The display unit 15 displays a visual inspection training table according to instructions from the display control unit 12. Moreover, the display control part 12 will complete | finish visual inspection training, if the completion | finish instruction | indication is received from the input part 11. FIG.

  The storage unit 13 stores a visual inspection training table. The visual inspection training table includes a character order tracking table in which a plurality of characters whose order is known is irregularly arranged and / or a figure search table in which a plurality of similar figures are irregularly arranged.

  When the display control unit 12 displays the visual inspection training table on the display unit 15, the timer unit 14 starts counting to measure the elapsed time. When the counter value reaches a value indicating a predetermined exercise time, the time measuring unit 14 notifies the display control unit 12 of the elapse of the predetermined exercise time. Note that the timer unit 14 is not limited to a counter and may be any unit that measures elapsed time.

  When the display control unit 12 is notified of the elapse of a predetermined training time from the time measuring unit 14, the display control unit 12 ends the display of the visual inspection training table currently displayed on the display unit 15. At this time, if an end instruction has not been received from the input unit 11, the display control unit 12 reads the next visual inspection training table from the storage unit 13 and causes the display unit 15 to display it.

  The visual inspection training table will be described below. In this embodiment, as the defect detection power, “instant vision” which is a force to grasp a lot of information in an instant, “eye movement force” which is a force to move eyes quickly, and “periphery” which is a force to view a wide range Use a visual inspection training table to improve "vision power". In other words, “peripheral visual acuity” is trained so that the entire visual field dimension can be seen, and “eye movement power” is trained so that each part within the visual field dimension can be quickly focused. By training you will be able to instantly determine whether it is a malfunction.

  FIG. 2 is a diagram illustrating an example of a visual inspection table according to the first embodiment. As an example of the character order tracking table included in the visual inspection training table, FIG. 2 shows a “number tracking table” in which numbers from 1 to 56 are irregularly arranged. The user follows the numbers that are irregularly arranged in the “number tracking table” displayed on the display unit 15 of the visual inspection training apparatus 1 in order, and follows 1 to 56 in 90 seconds. At this time, the display control unit 12 may cause the display unit 15 to display a message instructing the numbers to be traced together with the “number chart”. Irregular means that the user cannot infer the arrangement of the other part from the part of the arrangement.

  FIG. 3 is a diagram illustrating an example of a visual inspection table according to the first embodiment. As an example of the figure search table included in the visual inspection training table, FIG. 3 shows a “symbol search table” in which 204 symbols having similar shapes are arranged irregularly. The user searches for predetermined symbols among the symbols arranged irregularly in the “symbol search table” displayed on the display unit 15 of the visual inspection training apparatus 1 for 50 seconds, and counts how many. At this time, the display control unit 12 may cause the display unit 15 to display a message instructing to count a predetermined number of symbols together with the “symbol search table”.

  FIG. 4 is a diagram for explaining the visual inspection training method according to the first embodiment. FIG. 4A is a diagram illustrating movement of the exemplary user's line of sight at the time of visual inspection training in the “number tracking table” by using a circle and an arrow. First, the user finds “1”, and in order from “1” to “2”, “3”, “4”, “5”, “6”. Follow with your eyes.

  By performing visual inspection training using the character order tracking table, it is possible to train “eye movement power” and “peripheral visual field power”. The characters used in the character order tracking table are not limited to the numbers as shown in FIG. 4A, and may be characters having a known order such as the alphabetical order or the alphabet.

  Character size, character spacing, and line spacing with high training effect of the character order tracking table were character sizes of 8-12 mm, character spacing of 10-15 mm, and line spacing of 15-25 mm. The total number of characters may be changed according to the user's level of defect detection. For example, the total number of characters is divided into three stages of 36, 49, and 56. In order to find a working defect occurring on an actual electronic circuit board, it is necessary to detect in about 2.0 to 1.0 seconds per field of view, so in the example of FIG. The total number of characters is 1.6 seconds. In this way, the character order tracking table can adjust the training load by increasing / decreasing the total number of characters, so the character according to the user's level of defect detection, the rate of product defects, and the type of defect Prepare a follow-up table.

  FIG. 4B is a diagram showing the movement of an exemplary user's line of sight at the time of visual inspection training in the “symbol look-up table” by ○ and an arrow. First, the user searches for a predetermined symbol in the right direction using the middle symbol of the first row as a reference point. In FIG. 4B, the predetermined symbol is “⊃”. If there is a “mochi”, count the number. When you reach the rightmost symbol, you return to the reference point and search for “⊃” in the left direction. If there is a “mochi”, count the number. This is repeated in order from the top, and the number of “⊃” is counted. In the example of FIG. 4B, “⊃” is one surrounded by a broken circle. The search for the predetermined symbol from the reference point may be started from the left direction.

  By performing visual inspection training using the figure search table, it is possible to train “instant vision” and “peripheral visual acuity”. In the figure search table for finding “⊃” shown in FIG. 4B, similar figures “∈”, “∋” “⊆” “⊇” “⊂” “∪” “∩” are arranged side by side. Yes. The figure used for the figure search table is not limited to the symbol as shown in FIG. Similar figures may have the same outline or the same color, size, or open / close line figure, and the user may determine that they are the same in an instant view, or they may not be distinguishable It is a certain figure.

  The figure size, figure interval, and line spacing of the figure search table with high training effects were 8-12 mm, 10-15 mm, and 15-25 mm between lines. The total number of figures should be changed according to the level of defect detection power of the trainee. For example, the total number of figures is divided into three stages of 48, 150, and 204. In this way, the figure search table can adjust the training load by increasing or decreasing the total number of figures, so the figure search that matches the user's level of defect detection, the rate of product defects, and the type of defects Prepare a table.

  FIG. 5 is a flowchart illustrating an example of the operation of the visual inspection training according to the first embodiment. The visual inspection training process starts when the visual inspection training apparatus 1 is turned on.

  When the input unit 11 receives an input of a visual inspection training start instruction from the user (step S11; YES), the input unit 11 sends a visual inspection training start instruction to the display control unit 12. When the input unit 11 does not accept the input of the visual inspection training start instruction by the user (step S11; NO), step S11 is repeated.

  When receiving a start instruction from the input unit 11, the display control unit 12 reads the visual inspection training table from the storage unit 13 (step S12), and starts displaying on the display unit 15 (step S13).

  The timer 14 starts counting to measure the elapsed time, and when the counter value reaches X (step S14; YES), notifies the display controller 12 that the training time X has elapsed. When the counter value is not X (step S14; NO), the timer unit 14 repeats step S14. The training time X may be determined in accordance with the level of the user's defect detection power, the occurrence rate of defects in the product, and the type of defect.

  When notified from the time measuring unit 14 that the training time X has elapsed, the display control unit 12 ends the display of the currently displayed visual inspection training table on the display unit 15 (step S15).

  When the input unit 11 receives an input of a visual inspection training end instruction from the user (step S16; YES), the input unit 11 sends a visual inspection training end instruction to the display control unit 12. When the input unit 11 has not received the input of the visual inspection training end instruction by the user (step S16; NO), the process returns to step S12, and steps S12 to S16 are repeated.

  Upon receiving the end instruction from the input unit 11, the display control unit 12 determines whether or not the visual inspection training device 1 is turned off (step S17). If the power is not turned off (step S17; NO), the process returns to step S11, and steps S11 to S17 are repeated. If the power is turned off (step S17; YES), the process is terminated.

  As described above, according to the visual inspection training of the first embodiment, it is possible to improve the defect detection power of the visual inspection or to prevent a decrease in the defect detection power due to aging. In addition, forging the defect detection ability of the user engaged in the visual inspection decreases the outflow defect rate or increases the number of defect detections, so that the manufacturing quality of the electronic circuit board can be expected to be stable. In addition, since the user can move the eyes smoothly, the user feels as if the field of view has widened, and it becomes easier to find defects, and it seems that defects appear in the field of view. The effect of reducing and maintaining visual inspection for a long time can also be expected.

Or you may acquire from the card reader which the input part 11 reads an IC card, and may acquire from authentication apparatuses, such as fingerprint authentication. The input unit 11 sends a received instruction to start the defect detection test to the display control unit 12.

  When the display control unit 12 receives a start instruction from the input unit 11, the display control unit 12 reads out the defect power test table from the storage unit 13, displays it on the display unit 15, and starts the defect power test. In the defect detection test, the user finds a preset correct character from the characters arranged in the defect detection test table, and inputs information indicating the position of the found character to the input unit 11 as an answer.

  The display control unit 12 causes the display unit 15 to display a message instructing to find the correct character together with the defect power test table. The correct character may be fixed for each defect power test table, or may be changed each time a defect power test is performed.

  The input unit 11 receives an input of a user's answer and information for identifying the user, and sends the input to the counting unit 16. The totaling unit 16 stores the user response received from the input unit 11 and the information for identifying the user in the storage unit 13 in association with each other. The storage unit 13 stores information in which a user's answer is associated with information for identifying the user.

  The storage unit 13 stores a defect power test table. The defect power test table is a table in which a plurality of characters or figures are irregularly arranged. In addition, the storage unit 13 stores correct answer information indicating a correct character in association with the defect power test table. When the correct answer is changed every time the defect detection test is performed, the correct answer information is updated each time.
