The member feeder 5C) and the dispenser unit 6 are mounted on a common feeder base 16a (see FIG. 2). The tape feeder 5 feeds a carrier tape containing electronic components and workpieces to a take-out position by a mounting head of a component mounting mechanism described below by pitch-feeding in the tape feeding direction.

  The dispenser unit 6 has a function of applying a paste such as an adhesive for bonding components from the lower surface side to an electronic component or work taken out by the mounting head. Here, an example is shown in which the above-described type of tape feeder 5 and dispenser unit 6 are disposed only on the one-side component supply unit 4, but the same configuration may be applied to the other-side component supply unit 4 as well. Good.

  A Y-axis moving table 7 having a linear drive mechanism is disposed in the Y direction (a direction perpendicular to the X direction) at one end in the X direction on the upper surface of the base 1a. Similarly, two X-axis moving tables 8 each having a linear drive mechanism are coupled to 7 so as to be movable in the Y direction. A mounting head 9 is mounted on each of the two X-axis moving tables 8 so as to be movable in the X direction.

  Next, the measurement member 21 and the cleaning member 22 taken out from the measurement member feeder 5B and the cleaning member feeder 5C will be described with reference to FIG. The measuring member 21 is used as a dummy workpiece in trial application for the purpose of correcting the application position and adjusting the application amount in the paste application by the dispenser unit 6. The cleaning member 22 wipes the top surface 46c of the discharge nozzle 46 when cleaning the contamination due to the adhesion of the paste P, which occurs in the process of repeatedly executing the paste discharge by the dispenser unit 6 (see FIG. 7). Used as a wiping material.

  As shown in FIGS. 4A and 4B, the measurement member 21 and the cleaning member 22 are both housed and supplied in an embossed portion 18 a formed on an embossed tape type carrier tape 18. When the measurement member 21 and the cleaning member 22 are taken out from the measurement member feeder 5B and the cleaning member feeder 5C by the mounting head 9, the measurement member 21 and the cleaning member 22 in the embossed portion 18a are removed. In this state, the suction nozzle 10 is moved up and down to perform a component suction operation, whereby the suction nozzle 10 holds the upper surfaces of the measurement member 21 and the cleaning member 22 by vacuum suction.

  The measuring member 21 is a plate-like member having a flat lower surface 21a, and a plurality of application points 21b for trial application are formed in a regular arrangement (here, a lattice arrangement) on the lower surface 21a which is an application surface. In the trial application, the mounting head 9 holding the measurement member 21 is moved to the application execution position by the dispenser unit 6 (see FIG. 7), and the paste is sequentially applied to the plurality of application points 21b from below.

  That is, the electronic component mounting apparatus 1 shown in the present embodiment includes a measurement member supply unit that supplies the measurement member 21, and is used for measurement that is detachably attached to the feeder base 16 a as the measurement member supply unit. A member feeder 5B is used. The measurement member feeder 5B is configured to store and supply the measurement member 21 to the embossed portion 18a of the carrier tape 18 which is an embossed tape.

  The cleaning member 22 includes a first layer 22a that is a layer on the upper surface side, that is, a side that is held by the suction nozzle 10 of the mounting head 9, and a layer that is in contact with the discharge nozzle 46 (see FIG. 7) of the dispenser unit 6. The second layer 22b is at least two layers. As the first layer 22a, a material obtained by molding a rigid resin material or the like into a plate having a smooth upper surface so that the suction nozzle 10 can be stably sucked and held easily is used. The second layer 22b is made of a soft porous material such as a nonwoven fabric that can be impregnated and removed with the paste to be removed when the wiping surface 22c is brought into contact with the surface to be cleaned. In the configuration of the cleaning member 22, the second layer 22b is a softer layer than the first layer 22a.

  That is, the electronic component mounting apparatus 1 shown in the present embodiment includes a cleaning member supply unit that supplies the cleaning member 22, and the cleaning member supply unit is detachably attached to the feeder base 16a as the cleaning member supply unit. A member feeder 5C is used. The cleaning member feeder 5C is configured to store and supply the cleaning member 22 to the embossed portion 18a of the carrier tape 18 which is an embossed tape.

  Next, the configuration and function of the dispenser unit 6 will be described with reference to FIG. 5A, the main body 6a has mounting compatibility with a tape feeder 5 that is detachably mounted on a feeder base 16a provided on the carriage 16, such as a parts feeder 5A. Similarly, it can be detachably attached to the feeder base 16a. In the present invention, it is not essential that the dispenser unit 6 be detachably attached to the feeder base 16a. The dispenser unit 6 is disposed independently of the tape feeder 5 outside the feeder base 16a. You may make it do.

  At the front end portion of the main body 6a, a discharge mechanism 30 that discharges the paste to be applied is disposed with the discharge head portion 30a provided with the discharge nozzles 46 facing upward. A syringe 32 that discharges the stored paste P by air pressure is disposed behind the discharge mechanism 30 in an oblique posture, and a discharge pipe 31 and a pressure pipe 33 are connected to the discharge side and the pressure side of the syringe 32, respectively. ing. A float member 32 a for pressurizing the stored paste P is inserted inside the syringe 32, and a remaining amount detection sensor for detecting that the paste P has decreased to a predetermined level on the outer peripheral surface of the syringe 32. 32b is attached.

  The discharge pipe 31 and the pressurization pipe 33 are connected to the discharge head part 30a and the valve unit 34, respectively, and the valve unit 34 is further connected to an air supply source 36 via a regulator 35. The air supplied from the air supply source 36 is regulated to a prescribed air pressure by the regulator 35, and is turned on / off by the valve unit 34, so that the air is supplied to the syringe 32 through the pressurizing tube 33 for a prescribed valve opening time. Is done.

  The dispenser unit 6 has a controller 37 for controlling the paste discharge operation, and the controller 37 is connected to the discharge mechanism 30, the remaining amount detection sensor 32 b, the operation panel 38, the carriage 16, and the control device 50. The controller 37 executes control by a control command from the control device 50 and power supply from the carriage 16, thereby controlling the application operation of the paste P by the discharge mechanism 30. In the process in which the paste P is consumed with this application operation, the controller 37 detects a decrease in the paste P in the syringe 32 based on the detection result of the remaining amount detection sensor 32b. Further, a predetermined control operation by the controller 37 is possible by a manual operation command input via the operation panel 38.

  In the paste application by the dispenser unit 6 described above, the air pressure is regulated by the regulator 35 and the valve opening time of the valve unit 34 is controlled by the controller 37, whereby the paste P discharged from the syringe 32 to the discharge head portion 30a is controlled. The discharge amount can be adjusted, whereby the application amount applied by the discharge mechanism 30 can be adjusted. Therefore, the air pressure adjusted by the regulator 35 and the valve opening time of the valve unit 34 controlled by the controller 37 are parameters relating to the amount of paste applied. In the present embodiment, these parameters are stored in the storage unit 52 (FIG. 12) as application amount adjustment parameters 52c, and a desired application amount is obtained by operating the dispenser unit 6 based on these parameters. Be able to.

  Next, the configuration of the discharge mechanism 30 will be described with reference to FIG. In FIG. 5B, a discharge block 41 having a space 41a formed therein is erected on the upper surface of the horizontal base 40. The discharge block 41 is provided with a fitting hole 41b penetrating from the space portion 41a to the upper surface, and a piston 43 having a flange portion 43a at the lower portion is slidably fitted into the fitting hole 41b. . The piston 43 has a flange portion 43a supported from the lower surface side by a piezo element 42 disposed inside the space portion 41a. A disc spring member 49 is mounted on the upper surface of the flange portion 43a, and an urging force that presses the piston 43 against the piezo element 42 by constantly pushing down the piston 43 acts.

  The upper part of the piston 43 is fitted into a cylinder plate 45 disposed on the upper surface of the discharge block 41, and a discharge nozzle 46 is mounted on the upper surface of the cylinder plate 45. The cylinder plate 45 and the discharge nozzle 46 constitute a discharge head portion 30 a at the tip of the discharge mechanism 30. The discharge pipe 31 is connected to the discharge nozzle 46 via a joint portion 48, and the introduction hole 46 a formed in the discharge nozzle 46 in communication with the joint portion 48 is connected to the top surface of the piston 43 and the discharge nozzle. It communicates with a gap formed between the lower surface of 46. Further, an upper constricted storage space 46b is provided at a position communicating with the gap in the discharge nozzle 46, and the top of the storage space 46b opens to the top surface 46c to form a discharge hole 47. .

  The piezo element 42 has a property of expanding when a voltage is applied. In a state where no voltage is applied to the piezo element 42 (arrow a), the paste P sent from the discharge pipe 31 is introduced into the introduction hole. The storage space 46b is filled through 46a and the above-described gap. In this state, when a voltage is applied to the piezo element 42 via the wiring 44, the piezo element 42 is instantaneously expanded, whereby the piston 43 is instantaneously approached to the lower surface of the discharge nozzle 46. By one stroke of the piston 43, the paste P in the introduction hole 46a is pressurized, and a predetermined amount of paste P for a single shot is in the form of a discontinuous liquid paste P * through the discharge hole 47. The liquid is intermittently discharged upward (arrow b) against gravity. Then, by executing this single shot discharge a plurality of times at predetermined intervals, a desired amount of paste P is discharged from the discharge mechanism 30 and applied to the application object.

  Next, with reference to FIG. 6 and FIG. 7, processing that is performed along with paste application to the electronic component 20 in the mounting operation of the electronic component 20 will be described. First, as shown in FIG. 6A, the electronic component 20 taken out from the parts feeder 5A by the mounting head 9 moves above the component recognition camera 13, and the component recognition camera 13 images the electronic component 20 here. Done. And by recognizing the image acquired by this imaging, the position of the application position A set on the lower surface of the electronic component 20 and the electronic component 20 is recognized as shown in FIG.

  That is, ΔX, ΔY, and ΔΘ that respectively indicate the amount of positional deviation in the XYΘ direction from the optical system coordinate origin of the component center 20 (C) that indicates the center position of the electronic component 20 are detected. At the same time, a coating position A preset at a predetermined position on the lower surface of the electronic component 20 is detected. Here, the application position A is set to four diagonal positions outside the formation range of the bump 20a (not shown) on the lower surface of the electronic component 20, and the positions of the four application positions A in the optical coordinate system are acquired. Is done.

  FIG. 7 shows paste application to the electronic component 20 in which the application position A is detected in this way. That is, as shown in FIG. 7A, the mounting head 9 holding the recognized electronic component 20 is moved above the discharge head portion 30 a of the dispenser unit 6. Next, the suction nozzle 10 is lowered until the distance between the lower surface of the electronic component 20 that is the application surface and the top surface 46c of the discharge nozzle 46 reaches a predetermined application distance (see distance d shown in FIG. 13), and the application position The electronic component 20 is positioned in the horizontal direction so that A is positioned immediately above the discharge hole 47.

  In this state, the dispenser unit 6 is operated, and the liquid paste P * is intermittently discharged from the discharge hole 47 (arrow c) and applied to the lower surface of the electronic component 20. In other words, here, the discontinuous liquid mass paste P * is intermittently applied to the lower surface of the electronic component 20 taken out by the mounting head 9 against the gravity. At this time, in order to apply the prescribed amount of paste P to the application position A, the dispenser unit 6 discharges a predetermined amount of paste P in a plurality of shots.

  By this paste application operation, as shown in FIG. 7B, the paste P, which is an adhesive for component bonding, is applied to each corner portion set in advance at the application position A on the lower surface of the electronic component 20. . The application position A is set to a different position depending on the type of electronic component to be applied. For example, as illustrated in FIG. 7C, in the electronic component 20B that is a leaded component, one or a plurality of application positions A are set on the lower surface of the mold portion. Further, in the chip-type electronic component 20C which is a micro component, one application position A is set on the lower surface of the main body.

  FIG. 8 shows a paste recognition process executed on the electronic component 20 after the paste is applied. That is, the mounting head 9 holding the electronic component 20 after the paste P is applied by the dispenser unit 6 moves above the component recognition camera 13 as shown in FIG. Imaging for this is performed. Thereby, as the recognition screen 13a shown in FIG. 8B, an image including the recognition target paste P applied by the dispenser unit 6 is obtained with the application position A set on the lower surface of the electronic component 20 as a target. .

  FIG. 8C shows recognition processing for individual paste P. Here, the paste P0 indicated by a broken line centering on the application position A is a paste P to be applied to the application position A with a prescribed application area “S0” (here, the application area is regarded as the application amount). Yes, the paste P indicated by a solid line is the actual paste P detected by recognition. Here, in the recognition process, Δx, Δy indicating the positional deviation between the center P (C) of the paste P and the application position A obtained by a method such as area centroid detection and the application area [S] of the paste P The difference from the prescribed application area “S0” is calculated. Then, by comparing these calculation results with preliminarily stored determination threshold value data 52h (see FIG. 12), it is determined whether or not the application amount and application position of the paste P are within a predetermined range that is an allowable range. Determined.

  Next, adjustment of the application amount and correction of the application position performed based on the test application and the test application result performed on the measurement member 21 which is a dummy workpiece will be described with reference to FIGS. 9 and 10. . In the present embodiment, when the application amount or application position of the paste P applied to the electronic component 20 recognized by the recognition unit or any of these is out of the predetermined range, or when the paste P is newly set in the dispenser unit 6 In such a case, a trial for applying the paste P to the measurement member 21 in accordance with a predetermined trial application execution condition, for example, when a predetermined interval time or more has elapsed since the last application of the paste P. Application is performed.

  First, as shown in FIG. 9A, the mounting head 9 holding the measurement member 21 taken out from the measurement member feeder 5 </ b> B is moved above the discharge head portion 30 a of the dispenser unit 6. That is, the mounting head 9 transfers the measurement member 21 to the application execution position where the paste application can be performed by the dispenser unit 6. Next, the suction nozzle 10 is lowered until the distance between the lower surface of the measurement member 21 that is the application surface and the top surface 46c of the discharge nozzle 46 reaches a predetermined application distance, and trial application is performed on the lower surface of the measurement member 21. The horizontal position of the measurement member 21 is adjusted so that the target application point 21 b is positioned immediately above the discharge hole 47.

  In this state, the dispenser unit 6 is actuated to intermittently discharge the liquid paste P * from the discharge hole 47 (arrow d), and test-apply to the lower surface of the measurement member 21. That is, here, the discontinuous liquid mass paste P * is intermittently applied to the lower surface of the measuring member 21 taken out by the mounting head 9 against the gravity. In this trial application, the paste P is applied using a plurality of application points 21b set on the lower surface of the measurement member 21 as application target positions.

  At this time, for each application point 21b, the application of the paste P by a single shot is performed under conditions where the application conditions such as the application amount adjustment parameter 52c and the positioning control parameter 52f (see FIG. 12) are set differently. Accordingly, as shown in FIG. 9B, the paste P is applied to each application point 21b of the measurement member 21 at a different application amount and application position. By recognizing the result of the trial application, it is possible to empirically acquire the correlation between the application amount, the application position, and the application conditions. Note that the number of shots in a plurality of shots targeting the same application position may be included in the application conditions in the trial application.

  That is, as shown in FIG. 10A, the mounting head 9 holding the measurement member 21 on which the paste P has been applied by trial movement moves above the component recognition camera 13, and imaging for recognition is performed here. . That is, the mounting head 9 transfers the measurement member 21 to which the paste P has been applied to a recognition execution position that can be recognized by the recognition unit. Thereby, as a recognition screen 13a shown in FIG. 10 (b), a plurality of recognition target pastes P that have been trial-applied by the dispenser unit 6 with the application points 21b set at a plurality of locations on the lower surface of the measurement member 21 as targets.

The cleaning member 22 after being used for the cleaning operation is discarded in the disposal box 15. As the cleaning operation pattern, a pattern for moving the mounting head 9 in the rotation direction (θ direction) may be used, or an operation pattern combining a horizontal reciprocation and an operation in the rotation direction may be used.

  The above-described cleaning operation is executed not only when the recognition unit detects a defective application state in the electronic component 20 as described above, but also when the following conditions are satisfied. First, the interval of the application operation, that is, the discharge by the cleaning member 22 when a predetermined time elapses after the discharge mechanism 30 of the dispenser unit 6 applies the paste P until the next application is performed.

The valve opening time 52 d defines the length of time during which the valve is opened in the valve unit 34 in order to supply air into the syringe 32 and apply pressure to the paste P. The air pressure 52 e is the pressure of air supplied into the syringe 32 and applied to the paste P, and is defined by adjusting the regulator 35.

  The application amount adjusting unit 51b adjusts the application amount in a single shot based on the recognition result of the application amount in a single shot of the paste P by the dispenser unit 6 by the recognition unit. Here, the application amount is adjusted by adjusting a parameter (at least one of the valve opening time 52d and the air pressure 52e) relating to the application amount of the single shot paste. That is, the parameter relating to the application amount is adjusted based on the result of the recognition process shown in FIG. 10C (application area [Sn] of paste Pn).

  The positioning control parameter 52f is a machine parameter for positioning the application position of the paste P applied to the electronic component 20 (relative position of the mounting head 9 with respect to the dispenser unit 6). That is, by setting machine parameters that define the amount of movement of the Y-axis movement table 7 and the X-axis movement table 8 when the mounting head 9 is moved in the horizontal direction with respect to the dispenser unit 6, the suction nozzle 10 holds the machine head.

First, the uppermost position of the dispenser unit 6 mounted on the feeder base 16a, that is, the top surface 46c of the discharge nozzle 46 is set to be equal to or lower than the first height H1 that is the holding height. The first height H1 is lower than the third height H3 that is the coating height, and the third height H3 is equal to or less than the second height H2 and the fourth height H4 that are the moving height. It is set to become. In the example shown in FIG. 13, the third height H3 that is the coating height is set lower than the second height H2 that is the moving height, but an appropriate distance d is set. Depending on the case, the third height H3 may be set at the same height position as the second height H2.

At this time, the mounting head 9 moves the position of the electronic component 20 from the second height H2 to the third height so that the distance between the top surface 46c, which is the tip position of the discharge nozzle 46, and the electronic component 20 is a predetermined distance d. It operates to lower the height to H3. Thereafter, the lower end position of the suction nozzle 10 is moved from the third height H3 to the fourth height H4, which is the recognition height, and then the mounting head 9 is moved above the component recognition camera 13 to move the electronic component. 20 recognizes the paste applied.

  As described above, in the configuration in which the paste P is applied to the electronic component 20 held by the mounting head 9 by the dispenser unit 6, the distance between the discharge nozzle 46 and the electronic component 20 is a predetermined value for ensuring proper paste application. The mounting head 9 is operated so as to be the distance d. Thereby, the application shape and application position can be kept constant regardless of the component type, and variations in paste application results can be suppressed.

  Next, an electronic component mounting method in which the electronic component 20 is taken out from the parts feeder 5A by the mounting head 9 and transferred and mounted on the substrate 3 will be described with reference to the flow of FIG. This electronic component mounting method is selected when the allowable position accuracy of the applied paste P is severe and high-precision application position control is required, such as the electronic component 20A and the electronic component 20C shown in FIG.

The nozzle 46 is aligned (positioning step) (ST3). Next, as shown in FIG. 7A, the dispenser unit 6 is operated to apply the paste P to the predetermined application position of the held electronic component 20 (application process) (ST4).

  Thereafter, as shown in FIG. 8A, the mounting head 9 after the application process is moved above the component recognition camera 13 to recognize the paste P applied to a predetermined application position (paste recognition process) ( ST5). Here, the recognition processing unit 53 performs a recognition process for obtaining the application amount for each of the pastes P applied to the plurality of application positions A in the electronic component 20. Next, in the recognition result of the paste recognition process described above, it is determined whether or not the application amount of the paste P applied to the electronic component 20 is outside a predetermined range (ST6). This determination process is performed by the determination processing unit 54 referring to the determination threshold data 52h based on the recognition result by the recognition processing unit 53.

  If the application amount of the paste P is outside the predetermined range, the electronic component 20 is discarded in the disposal box 15 (ST7). If it is determined in (ST6) that the coating amount of the paste P is within the predetermined range, the electronic component 20 is aligned with the substrate 3 based on the component recognition result in the component recognition process in (ST2). And mounting (component mounting process) (ST8).

  Next, an electronic component mounting method in which the electronic component 20 is similarly taken out from the parts feeder 5A by the mounting head 9 and transferred and mounted on the substrate 3 will be described with reference to the flow of FIG.

Thereby, the position of the electronic component 20 is detected, and the application amount of the paste P applied to the electronic component 20 is obtained.

  Next, in the recognition result of the recognition process described above, it is determined whether or not the amount of paste P applied to the electronic component 20 is outside a predetermined range (ST15). Here, when the application amount of the paste P is out of the predetermined range, the electronic component 20 is discarded in the disposal box 15 as in the example shown in FIG. 14 (ST16).

  If the application amount of the paste P is within the predetermined range in (ST15), the electronic component 20 is aligned with the substrate 3 based on the recognition result of the electronic component 20 in the recognition process of (ST14). Mounting (component mounting process). According to the example shown here, since the number of times of recognition can be limited to only one after the paste application, it is possible to shorten the time required for component mounting work and improve productivity.
