Abstract

PROBLEM TO BE SOLVED: To provide a mounting component inspection apparatus with which even an inexperienced operator, when test results having mounting failures are continuously found at a certain component mounting position, can quickly understand the cause and take a measure, and to provide a method thereof.SOLUTION: When an operator selects a plot mark P displayed on a component mounting position map 79, a mounting defect detailed image 83 is displayed on a touch panel 64. At the time of the display, it is determined for each component mounting position whether or not a determination ratio of the mounting defect exceeds a predetermined threshold. When it is determined that the determination ratio exceeds the predetermined threshold, a message indicating "Estimated defect cause: Check the air discharge stop timing in a suction nozzle." is displayed. Thereby, even an inexperienced operator can easily and quickly understand that the cause of the mounting defect is due to pressure of air discharged from a lower surface of a suction nozzle 42 when the nozzle 42 ascends, and can quickly take a measure such as accelerating the timing of closing a blow valve 46.

Description

  The present invention relates to a mounted component inspection apparatus and a mounted component inspection method used in a component mounting apparatus for mounting a component on a substrate.

  When mounting components such as electronic components on a board, bonding materials such as cream solder are printed at a plurality of component mounting positions provided on the board, and the components stored in the component supply unit are picked up by suction nozzles. A method of picking up and mounting a suction nozzle that picks up a component by lowering it to a component mounting position on a substrate is widely used.

  The suction nozzle is provided with a suction pipe for sucking and holding components, and a vacuum suction source and an air source are connected to the suction pipe via a suction valve and a blow valve, respectively. When picking up a component from the component supply unit, the suction valve is opened and the blow valve is closed, whereby a vacuum pressure is supplied into the suction pipe, and a suction force is generated on the lower surface of the suction nozzle, so that the component is sucked and held. When mounting the component on the electrode, the blow valve is opened and the suction valve is closed, so that positive pressure is supplied into the suction line, and air is discharged from the lower surface of the suction nozzle (air blow), so that the electronic component Adsorption is released.

  This air discharge continues while the suction nozzle rises to a predetermined height after mounting in order to reliably separate the component from the suction nozzle. For this reason, peripheral components already mounted may be displaced due to the influence of air discharged when the suction nozzle is raised. In order to solve such problems, it is determined whether or not the suction position of the component by the suction nozzle is within the suction range that is assumed to have no air blow effect on the components around the mounting position on the board. And the method of preventing the position shift of the surrounding components by an air blow by discarding the components which are not adsorb | sucking within this adsorption | suction range is proposed (for example, refer patent document 1).

  However, in the component mounting operation, there is a variation in blow pressure for each suction nozzle, and the condition for causing the positional deviation by air blow is not always the same among mounted components, for example, the printed state of the solder is different at each component mounting position. For this reason, it is difficult to appropriately set the adsorption range for determining the disposal. Even when the above-described conventional technology is used, there may be a case where a mounting defect inspection result is continuously displayed at a certain component mounting position. However, if the worker who handles the component mounting device is an inexperienced person, he / she can not realize that the accuracy of detection of the warp deformation state of the board is insufficient as a cause of such mounting failure, and quick mounting I couldn't take measures against the defect.

  Therefore, the present invention provides a mounting component inspection apparatus and a mounting component inspection method that enable even an inexperienced worker to take quick measures against mounting failures when a mounting failure is continuously detected at a certain component mounting position on the substrate. The purpose is to provide.

  According to the third aspect of the present invention, a component is picked up from the component supply unit by the suction nozzle, and the pickup of the component is released by discharging air from the suction nozzle, so that a plurality of component mounting positions set on the substrate are set.

  According to a fourth aspect of the present invention, in the present invention according to the third aspect, in the notification step, the ratio or the number of times determined as a mounting failure by the determination step is mounted at a component mounting position that satisfies a predetermined condition. The adjacent distance between the power component and another component to be mounted adjacent to this component is calculated, and when it is determined that the calculated adjacent distance is within a predetermined numerical range, it is determined that the mounting is defective. A notification is made to confirm the timing of stopping the air discharge of the suction nozzle that has performed the mounting operation on the component mounting position where the ratio or the number of times satisfies a predetermined condition.

  According to the present invention, when there is a component mounting position at which the ratio or the number of times determined to be a mounting failure satisfies a predetermined condition, the air discharge stop of the suction nozzle that has performed the mounting operation on the component mounting position Since a notification to confirm the timing of this is performed, even a worker with little experience in the parts mounting field can understand the cause of mounting failure accurately, speeding up the timing of stopping the air discharge of the suction nozzle, etc. Can be taken quickly.

Take an image from above. Then, image recognition is performed based on the captured image of each electrode 3, and a print state inspection is performed to determine whether or not the cream solder is normally printed on each electrode 3.

  Next, the configuration of the component mounting apparatuses M3 to M5 will be described with reference to FIGS. Since the component mounting apparatuses M3 to M5 have the same structure, the component mounting apparatus M3 will be described as a representative. 2 and 3, in the center of the upper surface of the base 30, a pair of board transfer conveyors 31 constituting the first transfer line L1 and the second transfer line L2 and extending in the X direction are on the front side of the component mounting apparatus M3.・ Each is provided on the rear side. A pair of board | substrate conveyance conveyors 31 are supported on the base 30 by the pair of conveyor support member 32 provided facing the Y-axis direction. At the upper end of each conveyor support member 32, a pair of substrate end pressing members 32 a are provided so as to project over the substrate transfer conveyor 31.

  As shown in FIG. 3, in a state where the substrate 2 is held on a pair of substrate transfer conveyors 31, a substrate support mechanism 33 is disposed below the substrate 2. The substrate support mechanism 33 has a configuration in which a plurality of receiving pins 36 are erected in a vertical posture on a receiving base 35 that is moved up and down by a lifting drive unit 34. The lower receiving pin 36 is detachable from the lower receiving base 35.

  In FIG. 3, when the elevating drive unit 34 is driven and the lower receiving base 35 is raised from below with respect to the substrate 2 (arrow a), the lower surface 2 a of the substrate 2 comes into contact with the upper ends of the plurality of receiving pins 36. When the lower receiving base 35 is further raised, the substrate 2 stops at a position where the upper surface thereof is in contact with the lower surface of the substrate end pressing member 32a. Thereby, the board | substrate 2 is hold | maintained in the mounting work height position.

  2 and 3, a Y-axis movement table 37 extending in the Y-axis direction, two X-axis movement tables 38 movable in the Y direction with respect to the Y-axis movement table 37, and X A head moving mechanism 40 composed of two plates 39 that are movable in the X-axis direction with respect to the axis moving table 38 is disposed, and a mounting head 41 is mounted on each of the two plates 39. The mounting head 41 is a multiple-type head having a plurality of holding heads, and suction nozzles 42 are attached to the lower end portions of the respective holding heads so that the electronic components 4 are sucked and held and individually lifted and lowered.

  The suction nozzle 42 is provided with a suction pipe line 42a for picking up the electronic component 4, and a vacuum suction source 43 and an air source 44 are connected to the suction pipe line 42a via a suction valve 45 and a blow valve 46, respectively. It is connected. When the suction valve 45 is opened and the blow valve 46 is closed, a vacuum pressure is supplied into the suction pipe line 42a, and a suction force is generated on the lower surface of the suction nozzle 42 so that the electronic component 4 can be sucked. Further, when the suction valve 45 is closed and the blow valve 46 is opened, positive pressure is supplied into the suction pipe line 42a and air is discharged from the lower surface of the suction nozzle 42, so that the electronic component 4 of the suction nozzle 42 is sucked. If this happens, the adsorption is released. The mounting head 41 is mounted with a substrate recognition camera 47 that is located on the lower surface side of the X-axis moving table 38 and moves integrally to image the substrate from above.

  A plurality of tape feeders 48 as component supply units are mounted on both sides of the component mounting apparatus M3. The tape feeder 48 has a function of feeding the electronic component 4 to the component extraction position 48a by pitch-feeding a carrier tape (not shown) holding the electronic component 4. A component recognition camera 49 is provided between the tape feeder 48 and the board transport conveyor 31. The component recognition camera 49 is used to capture and recognize the electronic component 4 sucked and held by the suction nozzle 42 and detect a positional deviation of the electronic component 4 with respect to the suction nozzle 42.

  Next, the configuration of the control system will be described with reference to FIG. The control unit 50 provided in the component mounting apparatus M3 controls the following units constituting the component mounting apparatus M3. The control unit 50 controls the head moving mechanism 40, the mounting head 41, the tape feeder 48, and the board transport conveyor 31, so that the electronic component 4 located at the part extraction position 48a is picked up by the suction nozzle 42, or the board A component mounting operation is performed in which the suction nozzle 42 is lowered with respect to the substrate 2 transported by the transport conveyor 31, the suction of the electronic component 4 by the suction nozzle 42 is released, and the electronic component 4 is mounted on the electrode 3. In addition, when the control unit 50 controls the substrate support mechanism 33, a substrate support operation is performed in which the lower support pins 36 are raised to support the substrate 2 from the lower surface.

  A communication unit 51, a touch panel 52 as an input / output unit, and a storage unit 53 are connected to the control unit 50. The communication unit 51 exchanges control signals and data with other devices via the communication network 6 shown in FIG. The touch panel 52 is used for operation input for operating the apparatus, input of production data, and the like, and displays output information from the control unit 50. The storage unit 53 stores a mounting program and production information necessary for executing a board transfer operation and a component mounting operation.

  Next, the operation in the component mounting apparatus M3 will be described. When the control unit 50 detects that the substrate 2 has been transported from the upstream apparatus, the control unit 50 operates the substrate transport conveyor 31 to receive and transport the substrate 2, and positions the substrate 2 at a predetermined mounting work position. Next, the control unit 50 drives the elevating drive unit 34 to raise the lower receiving base 35 to which the lower receiving pin 36 is attached from below with respect to the substrate 2, whereby the lower receiving pin 36 is placed on the lower surface 2 a of the substrate 2. Abut the top. When the lower receiving base 35 is further raised in this state, the substrate 2 stops at a position where the upper surface abuts against the lower surface of the substrate end pressing member 32a while the lower surface 2a is supported by the lower receiving pins 36. If the upper surface of the substrate 2 stops at a position where it contacts the lower surface of the substrate end pressing member 32a, the control unit 50 drives the head moving mechanism 40 to move the substrate recognition camera 47 above the substrate 2. The substrate 2 is imaged and a positional deviation of the substrate 2 is detected.

  After imaging the board 2, the control unit 50 moves the mounting head 41 to the component extraction position 48a, and executes the pickup operation of the electronic component 4 sent to the component extraction position 48a. This pickup operation is performed by opening the suction valve 45 and closing the blow valve 46 and supplying the vacuum pressure into the suction pipe line 42a while bringing the lower surface of the suction nozzle 42 closer to the electronic component 4. Next, the control unit 50 moves the mounting head 41 that picks up the electronic component 4 above the component recognition camera 49, causes the component recognition camera 49 to pick up the picked-up electronic component 4, acquires image data, and acquires the image data. The suction position deviation of the electronic component 4 with respect to the suction nozzle 42 is detected by performing image recognition.

  After detecting the suction position deviation, the control unit 50 moves the mounting head 41 above the substrate 2 and executes the mounting operation of the electronic component 4 on the substrate 2. In the electronic component mounting operation, the controller 50 lowers the suction nozzle 42 relative to the component mounting position on the substrate 2 and discharges air from the suction nozzle 42.

  Here, the timing of the supply of the vacuum pressure and the discharge of air in the suction nozzle 42 will be described with reference to FIGS. From the initial position H1 before the suction nozzle 42 starts to descend (arrow b) to the time (t0 to t1) from when the suction nozzle 42 starts to descend to just before reaching the mounting position H2 which is the lowest position, The suction valve 45 is open and the blow valve 46 is closed. Therefore, a vacuum pressure is supplied into the suction pipe line 42a at the times t0 to t1, and the suction state of the electronic component 4 on the lower surface of the suction nozzle 42 is maintained.

  Then, by closing the suction valve 45 and opening the blow valve 46 at a time t1 immediately before the suction nozzle 42 reaches the mounting position H2, positive pressure is supplied into the suction pipe 42a, and air is supplied from the lower surface of the suction nozzle 42. The discharge state (arrow c in FIG. 6B) is brought about. With this state maintained, the suction nozzle 42 is lowered to the mounting position H2 to mount the electronic component 4 on the component mounting position (see FIG. 6B).

  When the electronic component 4 is mounted on the component mounting position, the suction nozzle 42 starts to rise from the state where the lower surface is at the mounting position H2 (arrow d shown in FIG. 6C). For a certain period after the start (t3 to t4 shown in FIG. 5), the air blowing is continued while the suction valve 45 is kept open and the blow valve 46 is closed (for this certain period (t3 to t4)). This is referred to as “post-mounting air blow duration time S”). The reason why the air blow is continued until a certain time has elapsed after the suction nozzle 42 starts to rise is to ensure that the electronic component 4 is separated from the suction nozzle 42 and mounted on the component mounting position. The post-mounting air blow duration time S is arbitrarily set by the operator. Then, by closing the blow valve 46 when the air blow duration time S after mounting has elapsed, the inside of the suction line 42a is in an atmospheric pressure state.

  The suction holding of the electronic component 4 is released by the above-described means, and the electronic component 4 is mounted at the component mounting position. In this mounting operation, the control unit 50 performs mounting position correction in consideration of the recognition result of the electronic component 4 by the component recognition camera 49 and the recognition result of the substrate 2 by the substrate recognition camera 47, and then performs the electronic component 4. Is mounted on the component mounting position of the board 2. The mounting substrate 5 that has been mounted by the component mounting apparatus M5 disposed at the most downstream of the component mounting apparatuses M3 to M5 is transported to the downstream mounting component inspection apparatus M6. That is, in the above configuration, the component mounting apparatuses M3 to M5 in the present embodiment pick up a component from the component supply unit by the suction nozzle, and release the component pickup by discharging air from the suction nozzle to be on the substrate. It has a function of mounting components at a plurality of set component mounting positions.

  Next, the mounting component inspection apparatus M6 will be described with reference to FIGS. 7 and 8, the mounting component inspection apparatus M6 includes a base 60, a pair of substrates that are provided on the base 60, transport the mounting substrate 5 on which the electronic component 4 is mounted, and position the mounting substrate 5 at the inspection position. The conveyance conveyor 61, the head moving mechanism 62 provided in the base 60, and the mounting state inspection head 63 moved by the head moving mechanism 62 are provided. The base 60 is provided with a touch panel 64 as an input / output device.

  The pair of board transfer conveyors 61 are provided on the front side and the rear side of the mounting component inspection apparatus M6 in a state extending in the X direction, and each board transfer conveyor 61 has a first transfer line L1 and a second transfer line L2, respectively. Part of it.

It consists of two plates 67 that are movable in the X-axis direction with respect to 66. The mounting state inspection head 63 is attached to each plate 67 and includes an inspection camera 63a with the imaging field of view facing downward. For this reason, the mounting state inspection head 63 moves the X-axis movement table 66 in the Y direction relative to the Y-axis movement table 65 constituting the head movement mechanism 62 and moves the plate 67 in the X direction relative to the X-axis movement table 66. It can be moved in the horizontal plane by combining with movement.

  The operation of transporting the mounting substrate 5 by the substrate transporting conveyor 61 is performed by the mechanism control unit 69 included in the control unit 68 included in the mounting component inspection apparatus M6 performing operation control of a substrate transporting conveyor driving unit including an actuator (not shown). Similarly, the movement operation of the mounting state inspection head 63 is performed by the mechanism control unit 69 controlling the operation of the head movement mechanism 62 described above.

  Next, the configuration of the control system of the mounted component inspection apparatus M6 will be described with reference to FIG. The control unit 68 includes a mechanism control unit 69, an inspection processing unit 70, and a storage unit 71. The inspection processing unit 70 includes an image processing unit 70a, a pass / fail inspection unit 70b, a count unit 70c, a statistical processing unit 70d, a determination unit 70e, and a display processing unit 70f. The storage unit 71 includes a program storage unit 72, an inspection data storage unit 73, an inspected mounting board target number storage unit 74, a mounting failure cumulative data storage unit 75, and a mounting failure determination ratio threshold value storage unit 76. .

  The above-described touch panel 64 is connected to the control unit 68, an input signal from the touch panel 64 is input to the control unit 68, and output information from the control unit 68 is displayed on the touch panel 64. That is, the output operation of the touch panel 64 is controlled by the control unit 68.

  Next, the storage unit 71 will be described. The program storage unit 72 stores a processing program for an inspection operation by the head moving mechanism 62 and the mounting state inspection head 63. The inspection data storage unit 73 stores component mounting position data 73a, mounting component data 73b, and inspection threshold data 73c. The component mounting position data 73a is data indicating the coordinate position on the board 2 of the component mounting position where the electronic component 4 is mounted on the board 2. The mounted component data 73b is data indicating the type of the electronic component 4 mounted at each component mounting position. The inspection threshold data 73c is data that defines an allowable positional deviation amount with respect to the normal position of the electronic component 4. The inspected mounting board target number storage unit 74 stores the target number of inspected mounting boards 5 necessary for the calculation of a mounting defect determination ratio described later. The mounting failure accumulation data storage unit 75 stores mounting failure accumulation data at each component mounting position subjected to statistical processing by the statistical processing unit 70d. The mounting failure determination ratio threshold value storage unit 76 stores a threshold value as to whether or not to display an estimated failure factor in a mounting failure detail image 83 to be described later.

  Next, the mechanism control unit 69 will be described.

The mechanism 78 to be provided is controlled.

  Next, the inspection processing unit 70 will be described. The image processing unit 70a receives the image data of the mounting board 5 imaged by the mounting state inspection head 63 via the CCU 77, and performs predetermined image processing such as detection of positional deviation of the electronic component 4 with respect to a predetermined component mounting position. The pass / fail inspection unit 70b compares the image processing result processed by the image processing unit 70a with each data stored in the inspection data storage unit 73 to determine whether or not the electronic component 4 is normally mounted on the electrode 3. The quality of the component mounting state is determined, and the determination result is output to the statistical processing unit 70d. Specifically, if the amount of deviation of the electronic component 4 from the predetermined component mounting position exceeds the threshold value stored in the inspection threshold value data 73c, it is determined that the mounting is defective. That is, the image processing unit 70a and the quality inspection unit 70b are determination units that determine the quality of the mounting state based on the imaging result of the imaging unit and output the determination result.

  When the determination result is output by this determination means, not only the mounting failure is determined but also the type of mounting failure is output together. Specifically, the determination means determines “component position deviation NG” when the mounting position of the electronic component 4 deviates from the normal position, and “parts” when the electronic component 4 is not mounted at the component mounting position. If the electronic component 4 is mounted upside down, it is determined as “reversed NG”, and if the electronic component 4 is mounted in the wrong mounting direction, “polarity NG” is determined. If foreign matter is mixed in the component mounting position, it is judged as “foreign matter NG”.

  The counting unit 70c counts the number of inspected mounting boards 5 that have been determined by the determination unit to determine whether the mounting state is good, and the number of inspected mounting boards 5 is stored in the inspected mounting board target number storage unit 74. When it is determined that the value has reached, a command is issued to the statistical processing unit 70d so as to calculate a mounting failure determination ratio described later.

  The statistical processing unit 70d accumulates and aggregates the determination results for each mounting board 5 by the determination unit, and performs predetermined statistical processing. Specifically, the number of times that mounting failure is determined for each component mounting position is counted, and the occurrence ratio of the type of mounting failure at each component mounting position is calculated. Further, the statistical processing unit 70d receives a command from the counting unit 70c, outputs the statistical processing result to the mounting failure accumulated data storage unit 75, calculates the proportion determined to be mounting failure at each component mounting position, and calculates the result. Is output to the mounting failure accumulation data storage unit 75. The mounting failure determination ratio is calculated by dividing the number of mounted substrates 5 that have been inspected from the number of mounting failures determined at each component mounting position. That is, the statistical processing unit 70d serves as a mounting failure determination ratio calculation unit that calculates a ratio determined as a mounting failure by the determination unit for each component mounting position.

  The determination unit 70e determines whether the mounting failure determination ratio at each component mounting position calculated by the statistical processing unit 70d exceeds the threshold value stored in the mounting failure determination ratio threshold value storage unit 76. To do. When it is determined that the mounting defect determination ratio exceeds the threshold value, a command is issued to the display processing unit 70f to perform display processing of the estimated defect factor described later on the component mounting position determined to have exceeded the threshold value. put out. That is, the determination unit 70e is a determination unit that determines, for each component mounting position, whether or not the ratio determined to be defective by the determination unit satisfies a predetermined condition.

  The display processing unit 70 f displays on the touch panel 64 an image indicating the component mounting position of the mounting board 5 that has been inspected. Further, the statistical processing data at each component mounting position stored in the mounting failure accumulation data storage unit 75 is displayed and output to the touch panel 64. Further, an estimated defect factor display process, which will be described later, is performed on the component mounting position at which the determination unit 70e determines that the mounting defect determination ratio has exceeded a predetermined threshold.

  FIG. 9 shows an image in which statistical processing data at each component mounting position stored in the mounting failure accumulation data storage unit 75 is displayed by the display processing unit 70 f and displayed on the touch panel 64. The image displayed on the touch panel 64 includes a component mounting position map 79 that displays, for each component mounting position, a portion determined to be defective on the board 2.

  A method for displaying a mounting failure determination location in the component mounting position map 79 performed by the control unit 68 will be described in detail. When the operator operates the cumulative display button 80 displayed on the touch panel 64 by touching it with a finger or the like, the display processing unit 70f is determined as a mounting failure on the image of the mounting board 5 displayed on the component mounting position map 79. Mounting failure determination data is displayed for the component mounting position. In the present embodiment, as a method for displaying mounting failure determination data, display is made using a plot mark P at a component mounting position determined as a mounting failure in the component mounting position map 79, and plotting is performed according to a mounting failure determination ratio. The color of the mark P is made different. The color assignment of the plot mark P can be confirmed by the color reference column 81 displayed on the touch panel 64. Thus, the worker can visually know the mounting failure determination ratio by comparing the color of the plot mark P displayed on the component mounting position map 79 with the color reference field 81.

  The color of the plot mark P assigned in accordance with the mounting failure determination ratio, the range of numerical values to which the color of the plot mark P is assigned, etc. can be arbitrarily set. When the cumulative reset button 82 displayed on the touch panel 64 is operated by the worker, the control unit 68 resets the stored mounting failure cumulative data, and newly starts the cumulative storage of the determination result from that point. .

  In the above configuration, the mounting failure accumulation data storage unit 75 is a storage unit that accumulates and stores the determination results for each of the component mounting positions for the plurality of mounting boards 5, and the display processing unit 70 f and the touch panel 64 are provided on the mounting board 5. The component mounting position map display means visually displays the component mounting position as a component mounting position map 79. The statistical processing unit 70d and the display processing unit 70f constitute a determination result accumulation display unit that displays the determination result accumulated and stored for each component mounting position on the component mounting position map 79.

  When the operator selects a plot mark P displayed on the component mounting position map 79, the control unit 68 displays a mounting defect detailed image 83 on the touch panel 64, which displays detailed information on the mounting defect in the plot mark P. . In the mounting failure detailed image 83, “board No.” indicating the type of the mounting board 5 to be inspected displayed on the component mounting position map 79, and in the case of a multi-sided board, a pattern to which the component mounting position belongs is displayed. “Pattern No.”, “Block No.” indicating the mounting order of the electronic component 4 mounted at the selected component mounting position on the substrate 2, and component mounting where the electronic component 4 is mounted at the selected component mounting position Mounted at a selected component mounting position among the plurality of suction nozzles 42 provided in the component mounting apparatuses M3 to M5 indicated by the “mounting machine No.” indicating the devices M3 to M5 and the “mounting machine No.”. “Use nozzle No.” indicating the suction nozzle 42 used for the mounting operation of the electronic component 4 that has been performed, and the tape feed that has supplied the electronic component 4 mounted at the selected component mounting position 44, “Supply Feeder No.”, “Defect Content” indicating specific contents of mounting failure, such as positional deviation of the electronic component 4 at the selected component mounting position or no component, and “Estimated Failure Factor: Adsorption nozzle The phrase “confirm timing of air discharge stop” is included.

  Regarding the “defect content” in the detailed mounting defect image 83 described above, since the content of the mounting defect at the selected component mounting position may be different for each unit mounting board, “component misalignment NG”, “no component NG”. , “Inversion NG”, “Polarity NG”, and “Foreign matter mixed NG” occurrence ratios are displayed as a pie chart. Thereby, it is possible to easily grasp the details of the mounting failure at each component mounting position. In addition, the phrase “estimated failure factor: confirm the timing of stopping air discharge from the suction nozzle” means that the proportion of component mounting positions where the plot mark P is displayed is determined as a mounting failure determination threshold value. Displayed for the component mounting position determined by the determination unit 70e that the threshold stored in the storage unit 76 has been exceeded. For example, when the determination unit 70e determines that the mounting failure determination ratio at a certain component mounting position exceeds the threshold value of 40%, the determination unit 70e outputs the determination result to the display processing unit 70f. 70f performs the display process of the said words on the touch panel 64 based on the said determination result. The threshold value may be arbitrarily set by the worker.

  As described above, in electronic component mounting in which the electronic component 4 is mounted on the substrate 2 and the mounting substrate 5 is manufactured, mounting defects may occur at a plurality of component mounting positions. In addition, there are various mounting failure determination ratios and types of mounting failures for each component mounting position. The occurrence of such mounting defects has a significant effect on the quality of the mounting board 5, so when a component mounting position with a high determination ratio of mounting defects occurs, the worker needs to determine the cause and take quick measures. There is. Here, the reason why an estimated failure factor is displayed in the mounting failure detail image 83 by the control unit 68 is that air blow performed when the electronic component 4 is mounted on the electrode 3 is one of the causes determined to be mounting failure. It can be considered that the other electronic component 4 already mounted on the surface 2 acts on the electronic component 4 for a long time and is pushed away by the wind pressure of the air blow. However, inexperienced workers cannot easily understand this cause and cannot take concrete measures. Hereinafter, the contents of the mounting failure that may occur due to the timing of stopping the air discharge of the suction nozzle 42 and the countermeasure method will be described.

  As described above, air blow at the time of mounting the electronic component 4 is performed only for a short time before and after the suction nozzle 42 contacts the electronic component 4 with the electrode 3. T4 shown in FIG. 5 indicates an appropriate time as the timing for closing the blow valve 46. When the blow valve 46 is closed at this timing, the electronic component 4A adjacent to the electronic component 4 that has finished the mounting operation is displayed. No influence is produced by the air discharged from the lower surface of the suction nozzle 42. However, the timing for closing the blow valve 46 is delayed due to a mistake in setting the control timing of the blow valve 46 (t4A shown in FIG. 5), and as a result, the post-mounting air blow duration time may increase from S to SA. Therefore, as shown in FIG. 10, after the suction nozzle 42 that has finished mounting the electronic component 4 on the electrode 3 starts to rise (arrow d), the wind pressure of the air discharged from the lower surface of the suction nozzle 42 is changed to the electronic component. When 4A receives for a long time, it may be pushed away from the electrode 3 (arrow e). Such a situation is prominent when the adjacent distance W between the electronic components 4 and 4A is narrow.

  When the control unit 68 displays “Estimated failure cause: confirm timing of air ejection stop of suction nozzle” on the mounting failure detail image 83, the worker displays “Mounting machine No.”, “ The suction nozzle 42 that has been pointed out is identified based on the content displayed in “Used nozzle No.” or the like, and the timing for closing the blow valve 46 is confirmed. If it is determined that this timing is late, the worker changes the timing of closing the blow valve 46 from t4A to t4 shown in FIG. 5 to shorten the post-mounting air discharge duration from SA to S. Take action. Thereby, the influence of the air blow with respect to 4 A of electronic components can be reduced, and the position shift of the electronic component 4 can be suppressed. Thus, by displaying the above-mentioned wording on the mounting failure detailed image 83, it is possible to notify the worker of the cause of the mounting failure and promptly execute the above-described mounting failure countermeasure.

  In the above-described configuration, the touch panel 64 and the control unit 68 that controls the touch panel 64 perform mounting work on the component mounting position for the component mounting position that is determined by the determination unit to be determined that the ratio determined to be mounting failure satisfies a predetermined condition. Informing means for informing that the timing of stopping the discharge of air from the suction nozzle that has been performed is confirmed.

  Next, a mounting component inspection execution flow will be described with reference to FIGS. First, the control unit 68 acquires inspection data of the predetermined number of mounting boards 5 necessary for calculating the mounting failure determination ratio (ST1). An execution flow for acquiring inspection data of the mounting board 5 will be described with reference to FIG.

  In FIG. 12, the mechanism control unit 69 controls the substrate transport conveyor 61 to carry the mounting substrate 5 into the mounting component inspection apparatus M6 (ST11). Next, the mechanism control unit 69 drives the head moving mechanism 62 to move the mounting state inspection head 63 onto the mounting substrate 5, and the inspection camera 63 a or a plurality of inspection images included in the imaging range of the inspection camera. A mounting component image of the mounting substrate 5 is acquired by imaging the component mounting position (ST12). That is, the mounting state inspection head 63 is an imaging unit that images the component mounting position on the substrate after mounting the component. The mounted component image is subjected to image processing by the image processing unit 70a, and based on the processing result, the pass / fail inspection unit 70b performs a pass / fail inspection of the mounting state at the component mounting position (ST13).

  Then, the pass / fail inspection unit 70b determines whether or not the mounting state of the component mounting position is good (ST14), and if it is determined that the mounting is defective, the pass / fail inspection unit 70b includes The inspection data is output to the statistical processing unit 70d (ST15). Then, the control unit 68 determines whether or not the pass / fail inspection for all the component mounting positions on one mounting board 5 is completed (ST16), and if the pass / fail inspection for all the component mounting positions is not ended. Returning to (ST12), mounting component images at other component mounting positions that have not yet been checked for pass / fail are acquired and similar processing is executed. If the control unit 68 determines that the quality inspection for all component mounting positions has been completed, the control unit 68 carries the mounting board 5 out of the mounting component inspection apparatus M6 (ST17). The carried-out mounting board 5 is counted by the counting unit 70c, and whether or not the statistical processing unit 70d has acquired the inspection data for the predetermined number of mounting boards 5 stored in the inspected mounting board target number storage unit 74. Judgment is made (ST18). If the predetermined number of sheets has not been reached, the process returns to ST11 and the inspection of the mounting board 5 is continued. By repeatedly executing the inspection process of the mounting board 5 in this way, the statistical processing unit 70d acquires the inspection data of the predetermined number of mounting boards.

  In FIG. 11, if the count unit 70c determines that the statistical processing unit 70d has acquired the inspection data for the predetermined number of mounting boards 5, the mounting at each component mounting position of the mounting board 5 with respect to the statistical processing unit 70d. A command is issued to calculate the defect determination ratio. In response to this instruction, the statistical processing unit 70d calculates a mounting failure determination ratio (ST2), calculates the mounting failure determination ratio at each component mounting position, the number of mounting failures at each component mounting position, and the mounting at each component mounting position. The statistically processed mounting failure cumulative data including the occurrence ratio of the types of failures is output to the mounting failure cumulative data storage unit 75, and the mounting failure cumulative data storage unit 75 stores this. Then, the display processing unit 70 f displays an image of the mounting board 5 including the component mounting position on the component mounting position map 79 based on the data stored in the mounting failure accumulation data storage unit 75.

  When the operator operates the cumulative display button 80 displayed on the touch panel 64, the display processing unit 70f uses the plot mark P to store the data stored in the mounting failure cumulative data storage unit 75 on the component mounting position map 79. Display processing. When the operator operates the plot mark P displayed on the component mounting position map 79, the above-described mounting failure detailed image 83 is displayed on the touch panel 64 by the display processing unit 70f.

  In the display processing of the mounting failure detailed image 83 by the display processing unit 70f, it is determined whether or not the mounting failure determination ratio at the component mounting position where the plot mark P is displayed by the determination unit 70e exceeds a predetermined threshold value. When it is determined for each component mounting position (ST3) and the determination unit 70e determines that the threshold value is exceeded, the determination result is output to the display processing unit 70f. Then, the display processing unit 70f receives the determination result and performs a process of displaying the estimated failure factor in the mounting failure detailed image 83 (ST4). After the mounting component inspection is completed, the mounting substrate 5 in which no defect is detected is carried into a reflow device 84 (see FIG. 1) connected to the downstream side, and the mounting substrate 5 is heated here to heat the substrate 2 and the electronic component 4. Are soldered together.

  In other words, component mounting is performed by picking up a component from the component supply unit by the suction nozzle and releasing the component pickup by discharging air from the suction nozzle to mount the component at a plurality of component mounting positions set on the board. In the mounting component inspection method for inspecting the mounting state of a component-mounted board that is unloaded from the device, mounting is performed based on the imaging process for imaging the component mounting position on the board after component mounting, and the imaging result of the imaging process. A determination process for determining whether the state is good and outputting a determination result, a storage process for accumulating and storing determination results for each component mounting position for a plurality of boards, and a component mounting position map on the board as a component mounting position map The component mounting position map display process to be displayed and the judgment results accumulated and stored for each component mounting position on the component mounting position map A determination result accumulation display step to be displayed, a determination step for determining whether or not a ratio determined as a mounting failure by the determination step satisfies a predetermined condition, and a ratio determined as a mounting failure in the determination step Including a notification step of notifying the component mounting position where it is determined that the predetermined condition has been satisfied, to confirm the timing of stopping the air discharge of the suction nozzle that has performed the mounting operation on the component mounting position; It has become.

  As a result, even if the worker has little experience in the component mounting field, the cause of mounting failure is the wind pressure of air discharged from the lower surface of the suction nozzle 42 when the suction nozzle 42 rises after the electronic component 4 is mounted on the electrode 3. It is possible to easily and quickly understand that it is caused by the above, and take measures such as speeding up the timing of closing the blow valve 46. As a result, it is possible to improve the productivity of the mounting board by advancing the timing of stopping the discharge of air and suppressing the occurrence of a mounting defective board caused by the air flowing out from the lower surface of the suction nozzle 42.

(Second implementation form)
Next, a second embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol is used for the same component as 1st Embodiment, and the description is abbreviate | omitted. In FIG. 13, in the second embodiment of the present invention, an adjacent distance calculation unit 70 g and an adjacent distance determination unit 70 h are newly added to the inspection processing unit 70, and an adjacent distance threshold value storage unit 85 is added to the storage unit 71. Newly added.

  In the second embodiment, whether the mounting failure determination ratio threshold value storage unit 76A calculates a distance (adjacent distance) between adjacent components to be described later based on the mounting failure determination ratio calculated at each component mounting position. Stores the threshold value of the defective mounting failure determination ratio. The adjacent distance threshold value storage unit 85 displays an estimated failure factor on the mounting failure detailed image 83 at the component mounting position where the mounting failure is determined based on the adjacent distance calculated by the adjacent distance calculating unit 70g described later. The threshold value of the distance between adjacent parts is stored.

  The determination unit 70eA determines whether or not the mounting failure determination rate at each component mounting position calculated by the statistical processing unit 70d exceeds the threshold value stored in the mounting failure determination rate threshold value storage unit 76. To do. When it is determined that the mounting defect determination ratio exceeds the threshold value, a command to calculate an adjacent distance described later is issued to the adjacent distance calculation unit 70g.

  Next, the adjacent distance calculation unit 70g and the adjacent distance determination unit 70h will be described with reference to FIG. Upon receiving a command from the determination unit 70eA, the adjacent distance calculation unit 70g receives an instruction from the electronic component (hereinafter referred to as “defective component 4B”) mounted at the component mounting position where it is determined that the mounting failure determination rate has exceeded a predetermined threshold. Shortest distance (adjacent to each other) between the normal mounting position of the electronic component 4 and the normal mounting position of the electronic component mounted adjacent to the electronic component 4 (hereinafter referred to as “adjacent components 4C1 to 4C4”). Distances W1-W4) are calculated. In calculating the adjacent distances W1 to W4, the adjacent parts 4C1 to 4C4 are specified by referring to the inspection data storage unit 73, and the normal mounting positions of the defective part 4B and the adjacent parts 4C1 to 4C4 are specified, Based on these data, the adjacent distances W1 to W4 between the defective part 4B and the adjacent parts 4C1 to 4C4 are calculated. In other words, the adjacent distance calculation unit 70g determines whether a component to be mounted at a component mounting position in which the ratio determined to be defective by the determination unit satisfies a predetermined condition and another component to be mounted adjacent to this component. It is an adjacent distance calculation means for calculating the adjacent distance.

  The adjacent distance determination unit 70h is a threshold range in which the adjacent distances W1 to W4 between the defective component 4B and the adjacent components 4C1 to 4C4 calculated by the adjacent distance calculation unit 70g are stored in the adjacent distance threshold storage unit 85. It is determined whether it is within. When it is determined that any one of the adjacent distances W1 to W4 is within the threshold value range, the adjacent distance determination unit 70h outputs the determination result to the display processing unit 70fA. That is, the adjacent distance determination unit 70h serves as an adjacent distance determination unit that determines whether or not the adjacent distance calculated by the adjacent distance calculation unit is within a predetermined numerical range.

  The display processing unit 70fA displays an image indicating the component mounting position of the mounting board 5 that has been inspected on the touch panel 64, and displays statistical processing data at each component mounting position stored in the mounting failure accumulated data storage unit 75. And output to the touch panel 64. Further, when the adjacent distance determination unit 70g determines that any one of the adjacent distances W1 to W4 calculated by the adjacent distance calculation unit 70g is within a predetermined threshold range, the adjacent distance determination unit 70g In response to the output of the determination result, “Estimated failure factor: confirm timing of air discharge stop of suction nozzle” is displayed on the mounting failure detailed image 83 at the component mounting position where the defective component 4B is mounted. Here, the fact that the adjacent distances W1 to W4 are within a predetermined threshold value means that the distance between the defective component 4B and the adjacent components 4C1 to 4C4 in the mounted state is narrow.

  That is, in the second embodiment of the present invention, the cause of the estimated failure is that the proportion of the component mounting positions where the plot mark P is displayed is determined to be a mounting failure in the mounting failure determination rate threshold storage unit 76A. The threshold range in which the distance to the adjacent electronic component 4 is stored in the adjacent distance threshold value storage unit 85 at the component mounting position determined by the determination unit 70eA as exceeding the set threshold value Is displayed with respect to the component mounting position determined by the adjacent distance determination unit 70h. The threshold value may be arbitrarily set by the worker.

  By setting the display condition of the estimated failure factor in this way, the electronic component 4 mounted at the component mounting position where the cause of the mounting failure is determined to be the mounting failure and the electronic component 4 mounted adjacent thereto are displayed. There is a possibility that the distance may be narrow and may be caused by the wind pressure of air continuously discharged from the suction nozzle 42 when the suction nozzle 42 rises after the electronic component 4 is mounted on the electrode 3. It can be further enhanced.

  The notifying means in the second embodiment of the present invention is determined to be a mounting failure when the adjacent distance determining means determines that the adjacent distance calculated by the adjacent distance calculating means is within a predetermined numerical range. It is configured to notify that the timing of stopping the air discharge of the suction nozzle that has performed the mounting operation at the component mounting position where the ratio satisfies a predetermined condition is confirmed.

  In the first and second embodiments described above, the display of the estimated failure factor in the mounting failure detailed image 83 is performed based on the ratio determined as mounting failure at the component mounting position where the plot mark P is displayed. However, it may be performed when the number of times determined to be mounting failure satisfies a predetermined condition (number of times). In other words, in the first embodiment, if the counting unit 70c determines that the number of inspected mounting boards 5 has reached a predetermined number, the mounting failure at each component mounting position statistically processed by the statistical processing unit 70d is determined. The determination unit 70e determines whether or not the determined number of times exceeds a predetermined threshold value. If the determination unit 70e determines that the predetermined threshold value is exceeded, the display processing unit 70f displays the mounting defect detail image 83 in the mounting defect detailed image 83. Then, the process of displaying the estimated failure factor may be performed. That is, in the first embodiment, the determination means (determination step) is configured to determine, for each component mounting position, whether or not the ratio or the number of times determined as defective mounting satisfies a predetermined condition, and also provides notification. The means (notification process) performed the mounting operation on the component mounting position for the component mounting position determined that the ratio or the number of times determined as defective mounting in the determining means (determination process) satisfied a predetermined condition. Notification is made to confirm the timing of stopping the air discharge of the suction nozzle.

  In the second mounting mode, if the count unit 70c determines that the number of inspected mounting boards 5 has reached a predetermined number, the mounting failure at each component mounting position statistically processed by the statistical processing unit 70d is determined. The determination unit 70eA determines whether or not the determined number of times exceeds a predetermined threshold value. If it is determined that the predetermined number of times is exceeded, the adjacent distance calculation unit 70g is determined to be defective in mounting. The regular mounting position of the electronic component 4 mounted at the component mounting position determined that the number of times exceeds the predetermined threshold and the regular mounting of other electronic components mounted adjacent to the electronic component 4 The adjacent distance W with the position is calculated, and the adjacent distance determination unit 70h determines whether or not the adjacent distance W between the electronic components calculated by the adjacent distance calculation unit 70g is within a predetermined threshold range. Based on this judgment result May be to perform the display of the estimated insufficiency cause on the display unit 70f is mounted defective detailed image 83. That is, in the second embodiment, the adjacent distance calculation means is mounted adjacent to a component to be mounted at a component mounting position where the ratio or number of times determined as defective mounting by the determination means satisfies a predetermined condition. It is configured to calculate the adjacent distance to other parts to be. In addition, the notification unit determines that the adjacent mounting distance calculated by the adjacent distance calculating unit is within a predetermined numerical range, and the component mounting position at which the ratio or number of times determined as mounting failure satisfies a predetermined condition. Is configured to notify that the timing of stopping the air discharge of the suction nozzle that has performed the mounting operation is confirmed.

  The mounting component inspection apparatus and the mounting component inspection method of the present invention effectively uses the inspection result information obtained in the mounting component inspection to set the timing of the air discharge stop of the suction nozzle, thereby enhancing the usefulness of the mounting component inspection. This is advantageous in that it can be improved and is useful in the field of inspecting the mounting state of components mounted on a substrate.
