A film feeding device that includes a pair of rollers that sandwich the film drawn from the film storage device from both the front and back sides and a rotation driving device that rotationally drives at least one of the rollers, and that feeds the film in a feeding direction parallel to the longitudinal direction;
(a) The free end portion of the film fed by the film feeding device is adsorbed and held by the film holding surface on which the suction holes are formed, and a first blade is provided on one upstream edge in the feeding direction. A film holding table, (b) a second blade for shearing the film in cooperation with the first blade, and (c) the second blade and the first blade in a direction perpendicular to the film holding surface. A film shearing device that shears the film by the first blade and the second blade and separates the free end held by the film holding base from the main body of the film. A film feeder characterized by that.
This film feeder was developed as a solder film feeder that cuts and supplies a tape-shaped solder film to a desired length, and is particularly suitable for supplying a solder film. Any film that can be extruded onto the film holding table of the film shearing device by the feeding device can be cut in the same manner, and this film feeder is not limited to the solder film supply. Examples of the film include a connection film used for connection of a plurality of members, for example, a mechanical, electrical, and chemical connection, a display film on which characters, figures, etc. are written and attached to an object. Yes, the solder film is an example of a connection film. In addition to the solder film, the connection film includes, for example, an anisotropic conductive film, an adhesive film, and an adhesive film.
The relative movement device may be configured such that the first blade is a movable blade and is moved with respect to the second blade which is a fixed blade, and the second blade is a movable blade and is moved with respect to the first blade which is a fixed blade. Alternatively, both the first and second blades may be moved as movable blades. Further, the relative movement device may be a lifting device, the first blade may be an upper blade, the second blade may be a lower blade, and vice versa.
The film can also be supplied by cutting in advance to a predetermined length and holding the film in a state where it is arranged in a line on a holding tape having a longitudinal shape. However, in this case, the length of the supplied film is determined as one type, and it is impossible to cope with the required change in the length of the film. On the other hand, according to this film feeder, since a longitudinal film is supplied by being sheared by a film shearing device, it is possible to supply a film having a desired length, which is convenient.
Further, since the film is adsorbed and held on the film holding surface, it can be reliably sheared without being lifted off from the film holding surface during shearing. Furthermore, even if the free end portion of the film is sheared and separated from the main body portion, it does not come off the film holder.

However, it is often convenient to hand over the cut end of the film to the supply target by raising the film holding table having the upward film holding surface together with the first blade to shear the film. For example, the rising end position of the film holding table can be the delivery position of the film held on the film holding surface to the supply target, and in that case, the film holding table for cutting the film The upward movement is advantageous because it also serves as an upward movement for film delivery. It should be noted that the film supply target is a suction tool having a suction hole that opens to the lower end surface, that is, the rising end position of the film holding base is the film suction position (at the suction height by the suction tool).

The film can be lowered in a direction perpendicular to the surface, which is desirable from the viewpoint of the stability of the film transfer operation, and in this case, the film holding surface of the adsorber and the film feeder may be used. There is no risk of interference with adjacent parts.
However, from the viewpoint of improving the efficiency of the delivery work, it is desirable that the lowering distance of the suction tool and the rising distance of the film holder are short, and part of the movement and lowering movement in the direction perpendicular to the axis of the suction tool is It is desirable to do so in parallel. And in that case, it is necessary to avoid that the adsorbing tool and the transport head interfere with the portion of the film feeder adjacent to the film holding surface. For this reason, the film holding surface is adjacent to the film feeder. It is desirable that it be raised to almost the same level as the upper end surface of the portion.
In general, from the viewpoint of ensuring interference between the receiving side during film reception and the film feeder, the rising end position of the film holding surface is the same as the upper end surface of the portion adjacent to the film holding surface of the film feeder. A level is particularly desirable, and a higher level is desirable than a low level. That is, it is desirable that the level be equal to or higher.

  The sheet 502 is fed by a predetermined length as the take-up reel 520 is rotated by the reel rotation driving device 522, and the part actually supported by the sheet support base 510 is retracted from the support surface 540 and is not used. A portion is positioned on the support surface 540. The feed length of the sheet 502 is detected by the feed amount detection device 550. The feed amount detection device 550 is provided in the unit main body 504 and detects the feed amount by detecting the rotation angle of the roller 544. Further, as shown in FIG. 9, a container 552 that opens upward is attached to the side surface of the unit main body 504. In the state where the film feeder 300 and the flux check unit 500 are attached to the feeder holding base 260, as shown in FIG. 2, the front part is located in the cover 180 through the opening 188, and the rear part is outside the cover 180. It will be in the state located.

  The plurality of assembly work machines 20 constituting this assembly work system are arranged without gaps, and the worker cannot access the assembly work machine 20 from the side, but accesses from the front and rear. Therefore, as shown in FIG. 2, the ceiling panel 186 of the cover 180 is provided with an opening 600 following the opening 188 at the front thereof, so that the operator can see the inside of the assembly machine 20 from above the front of the assembly machine 20. Have been able to access. Access is also possible from the opening 188, but the accessible range is limited to the front part of the assembly machine 20, whereas the central part can also be accessed.

  The opening 600 has the same width as the opening 188 and is closed by opening / closing doors 602 and 604 attached to the ceiling panel 186. The open / close doors 602 and 604 are provided side by side in a direction parallel to the base material transport direction, and are attached to be rotatable about an axis parallel to the base material transport direction by a hinge (not shown). The width and depth of the opening / closing door 602 are larger than those of the opening / closing door 604. An operator can access at least one of the open / close doors 602 and 604 to access the inside of the assembly work machine 20 through the opening 600.

  The tray-type supply device 200 and the feeder-type supply device 202 provided side by side in the width direction on the carriage 204 are such that the tray-type supply device 200 is located on the open / close door 602 side and the feeder-type supply device 202 is located on the open / close door 604 side. To do. Further, the tray type supply device 200 is provided in a state facing one side portion of the opening 188 in a direction parallel to the substrate transport direction, and the feeder type supply device 202 is placed in a state facing the other side portion. Provided. In other words, the tray-type supply device 202 is disposed in a state that does not face the portion on the other side of the opening 188, and the feeder-type supply device 202 is provided in a portion that does not face the tray-type supply device 200 in the opening 188. .

  Therefore, in a state where the supply device 34 is attached to the base 50 in the carriage 204, the stocker 222 and the stocker lifting device 224 of the tray-type supply device 200 are positioned in front of the opening / closing door 602 and enter the assembly machine 20 of the operator. Hinder access. The tray type supply device 200 is configured such that the stocker 222 is moved up and down over the supply height, has a large vertical dimension, and is larger than the portion of the work machine body 30 where the base material conveyance holding device 32 is provided. It extends upward and is positioned in front of the opening / closing door 602, thereby preventing the operator from operating the opening / closing door 602. If the carriage 204 is removed from the base 50 and the supply device 34 is removed from the base 50, the operator can access the inside by opening the door 602, but this is troublesome.

  On the other hand, the feeder holding base 260 is located on the opening / closing door 604 side, but the film feeder 300 and the flux check unit 500 attached to the feeder holding base 260 have a smaller vertical dimension than the tray type supply device 200, and the height direction. In FIG. 4, the working machine body 30 is only located in the vicinity of the portion corresponding to the portion provided with the base material conveyance holding device 32. Therefore, the opening / closing door 604 remains open forward, and the operator can open the opening / closing door 604 and access the device inside the assembly work machine 20 through the opening 600 to perform maintenance and the like. By allowing the opening 600 to be blocked by the two open / close doors 602 and 604, the operator opens one of the open / close doors 604 while the supply device 34 is attached to the base 50, and the assembly work machine 20. It is possible to access the inside. In particular, the opening / closing door 604 is smaller than the opening / closing door 602 and is separated from the tray-type supply device 200 in the width direction, so that the opening / closing operation can be performed without fear of interference with the tray-type supply device 200.

  Thus, although the tray type supply device 200 has a high height, since the film feeder 300 and the flux check unit 500 are low in height, the portion of the opening 188 that does not face the tray type supply device 200 is The upper side of the film feeder 300 and the flux check unit 500 is in a state of being present. Further, if the film feeder 300 or the like is attached to a part of the plurality of holding portions 262 of the feeder holding base 260, there is a portion where the film feeder 300 or the like of the feeder holding base 260 is not attached. If it is not attached, the entire portion where the feeder holding base 260 of the opening 188 is located is in a state of being present.

  As shown in FIG. 2, an opening / closing door 606 is attached to the opening 188 in order to cover a portion of the opening 188 that does not face the tray type supply device 200. In FIG. 1, the opening and closing door 606 is not shown. The opening / closing door 606 includes a main body portion 608 that closes the upper gap of the film feeder 300 and the like, and an auxiliary portion 610 that closes the lateral gap, and the side panel 182 is vertically moved by hinges 612 and 614 (see FIG. 2). It is attached so as to be rotatable around an axis parallel to, and can be opened and closed by an operator. The width of the side gap of the film feeder 300 or the like is determined by the number of film feeders 300 or the like attached to the feeder holding base 260. Therefore, the auxiliary portion 610 having a width corresponding to the width of the gap on the side side is detachably attached to the lower surface of the main body portion 608 and is rotated integrally with the main body portion 608. If there is no gap on the side, the auxiliary part 610 is not attached to the main body part 608, only the main body part 608 is attached to the side panel 182, and the open / close door 606 is constituted only by the main body part 608. . The opening / closing door 606 is provided so as to block a portion of the opening 188 where the film feeder 300 and the flux check unit 500 are not provided, so that the portion where the film feeder 300 and the flux check unit 500 are disposed is outside the cover 180. The opening portion 616 that allows the protrusion of the opening portion 616 is included. The opening / closing door 606 is prevented from opening beyond 90 degrees.

  As shown in FIG. 2, a protrusion 620 is formed on a portion corresponding to the opening / closing door 604 on the upper surface of the main body 608 when the opening / closing door 606 is in a closed state and covers a portion of the opening 188 that does not face the tray-type supply device 200. Is provided and constitutes a locking portion which is an erroneous operation preventing portion. In this embodiment, the protrusion 620 is long in a direction orthogonal to the rotation axis of the main body 608. Further, an engagement piece 622 is attached to the free end portion of the opening / closing door 604 to constitute a locking portion which is an erroneous operation preventing portion. In this embodiment, the engagement piece 622 is formed by bending a plate material as shown in FIG. 19, and is provided in a state protruding from the edge of the free end of the opening / closing door 604, and has the same width as the opening / closing door 604. Have.

  Opening / closing of the opening / closing door 604 is detected by an opening / closing detection device 630 (see FIG. 21). The open / close detection device 630 is configured by a transmissive photoelectric sensor in the present embodiment, and is provided on the front surface of the side panel 182. When the open / close door 604 is closed, the open / close detection device 630 prevents the light receiving unit from receiving light by a dog 632 (see FIG. 19), which is a detected portion, provided on the inner surface of the open / close door 604. In the opened state, light reception is not hindered, and a different signal is output depending on whether the door 604 is opened or closed.

  In a state where the opening / closing door 606 is in an open state that does not cover the portion of the opening 188 that does not face the tray-type supply device 200, the protrusion 620 is positioned within the rotation locus of the engagement piece 622 of the opening / closing door 604. Therefore, if the operator tries to close the opening / closing door 604 in a state where the opening / closing door 606 is not closed, the engagement piece 622 comes into contact with the protrusion 620 to prevent the rotation to the closed position. Since the protrusion 620 and the engagement piece 622 are both long and the opening / closing door 606 is prevented from opening beyond 90 degrees, the opening / closing door 606 is positioned at any position other than the closed position. Even if the opening / closing door 604 is not closed, if the opening / closing door 604 is to be closed, the engagement piece 622 hits the protrusion 620 and the opening / closing door 604 is prevented from being closed. Therefore, the open / close detection device 630 still outputs an open signal indicating that the open / close door 604 is opened, and it is detected that the open / close door 604 is not closed.

  When the opening / closing door 606 is closed, the protrusion 620 is deviated from the rotation locus of the engagement piece 622 and is positioned in the assembly work machine 20, and the rotation of the opening / closing door 604 to the closed position is not hindered. Therefore, if the operator closes the open / close door 606 after closing the open / close door 606, the open / close door 604 can be rotated to the closed position and closed as shown in FIG. A close signal indicating that the door has been closed is output, and it is confirmed that the door 604 has been closed. In order to close the opening / closing door 604, it is necessary to close the opening / closing door 606. If it is detected that the opening / closing door 604 is closed, it is also guaranteed that the opening / closing door 606 is closed. The opening / closing detection device 630 also serves as a device for detecting each opening / closing of the opening / closing doors 604, 606, and only one opening / closing detection device is required.

As shown in FIG. 20, ruled lines are provided in a lattice shape on the assembly surface, which is the upper surface of the base material 12, and a position error is acquired by imaging the ruled lines. Projections and recesses are originally provided on the base material 12 on the work surface of the base material 12 and constitute the base material 12, and the position on the work surface can be specified by imaging. For example, it is also possible to calculate the position error of the part assembly location by taking an image of those in the vicinity of the component assembly location. The ruled line can be considered to be a generalized protrusion. A plurality of reference marks are provided on the surface on which the work of the substrate 12 is performed, and the reference marks are picked up by the image pickup device 42, whereby each position error and rotational position error in the X-axis and Y-axis directions of the component assembly location. May be acquired and the correction amount may be acquired.

  After imaging, the transport head 36 is moved to the supply device 34 by the head moving device 40, receives the solder film piece 702 from the film feeder 300, and takes out the component 14 from the tray 210. Any of these may be performed first, but first, reception of the film piece 702 will be described. In the film feeder 300, the solder film 302 is just cut, and the downstream end thereof is in a state of being coincident with the blades 450 and 452 in the film feeding direction. Further, the film holding table 460 is located at the lowered end position as shown in FIG.

  In the film feeder 300, first, the electric motor 376 is controlled by the individual control device 660 based on the feed signal from the overall control device 48, and the solder film 302 is fed by a predetermined length. The feed length is a length necessary for soldering the component 14 on the base 12 and is set in advance based on the size and shape of the component 14. From the overall control device 48 to the individual control device 660, a signal indicating the feed length is supplied together with the feed signal. Based on this, the electric motor 376 is driven by an amount necessary to feed the solder film 302 by the designated length, and the rollers 360 and 362 are rotated to feed the solder film 302 by the set length. In the state where the downstream end portion or the free end portion of the solder film 302 is pushed to the front end side of the film feeder 300 through the space between the blades 450 and 452 due to its rigidity and the feeding is finished, FIG. As shown, it protrudes from the blades 450 and 452 to the downstream side in the film feeding direction and is positioned on the film holding surface 474.

  After the feeding, the electromagnetic direction switching valve 482 is switched, the negative pressure supply passage 478 is communicated with the negative pressure source 480, negative pressure is supplied to the suction hole 476, and the solder film 302 is adsorbed to the film holding surface 474. In this state, the film holding table 460 is raised. As a result, the blade 450 is raised, the free end of the solder film 302 is sheared by the joint of the blades 450 and 452, and is separated from the main body of the solder film 302 (the portion upstream of the blade 452 in the film feed direction). A solder film piece 702 is obtained. After the solder film 302 is cut, the film holding table 460 is further raised toward the rising end position, and the film holding surface 474 is positioned at the suction height. It can be considered that the solder film 302 is thin and the solder film piece 702 adsorbed on the film holding surface 474 is also located at the adsorbing height. When the arrival of the film holding table 460 at the rising end position is detected by the rising end position sensor 492, a signal indicating completion of the rising is sent from the individual control device 660 to the overall control device 48.

  The transport head 36 is moved down in the horizontal direction by the X-axis direction moving device 60 and the Y-axis direction moving device 62, and is lowered by the Z-axis direction moving device 64 to approach the film feeder 300. Then, the film piece holder 130 is lowered with respect to the Z-axis slide 90 based on a signal for detecting the arrival of the film holder 460 at the rising end position. The film piece holder 130 is lowered to the descending end position where the suction surface 143 is positioned a short distance below the suction height. The excessive descending distance after the suction surface 143 contacts the solder film piece 702 is allowed by relative movement of the film piece holder 130 with respect to the shaft portion 137 of the suction portion 139. The film piece holder 130 is moved above the film holding table 460 before being lowered to the lowered end position, and is lowered at a right angle to the film holding surface 474 to attract the solder film piece 702.

  The fact that the film piece holder 130 is lowered to the lower end position and the solder film piece 302 is sucked is sent from the individual control device 652 to the individual control device 660 via the overall control device 48, and the electromagnetic direction switching valve 482 is moved. The suction hole 476 is switched to a state of communicating with the atmosphere. Thereby, the holding of the solder film piece 302 by the film holding surface 474 is released, and the film piece holder 130 holds the solder film piece 702 and lifts it from the film holding surface 474. After releasing the holding of the solder film piece 302 by the film holding surface 474, the film holding table 460 is lowered. It should be noted that a negative pressure and a positive pressure are selectively supplied to the suction hole 476 so that the supply of the negative pressure to the film holding surface 474 is interrupted and the positive pressure is supplied, and the solder film by the film holding surface 474 is supplied. The holding of the piece 702 may be positively released.

  Next, the transport head 36 is moved to the tray 210 positioned at the supply position, and the component 14 is taken out. Which of the plurality of receiving recesses 212 of the tray 210 contains the component 14 is grasped by the overall control device 48, and the order of taking out the components 14 from the plurality of receiving recesses 212 is set in advance. The component holder 130 is moved and lowered above the housing recess 212 for taking out the component 14, sucks the component 14 and removes it from the tray 210.

  Next, the transport head 36 is moved upward to the substrate 12, but is moved upward to the image pickup device 44 and is held by the solder film piece 702 held by the film piece holder 130 and the component holder 130. Each component 14 is imaged, and each holding position error is acquired and sent to the individual control devices 652 and 656. The solder film 302 contains solder and is opaque, and the solder film piece 702 is opaque and can be imaged by the imaging device 44. The holding position error includes each position error and rotational position error in the X-axis direction and the Y-axis direction. These positional errors are caused by correcting the movement position of the transport head 36 when the solder film piece 702 and the component 14 are mounted on the substrate 12, respectively, and rotating the holder 132 to cause the film piece holder 130 and the component holder 130 to move. It is corrected by rotating. Further, if the posture (longitudinal direction) of the solder film piece 702 and the part 14 needs to be changed, the holder 132, the film piece holder 130, and the part holder 130 are rotated accordingly. The position error and the rotational position error obtained by imaging the part assembly location first are also corrected.

  First, the film piece holder 130 is moved and lowered onto the part assembly location, and the solder film piece 702 is accurately placed in a predetermined posture on the flux 700 applied to the substrate 12. After placement, the flux application head 38 is moved onto the solder film piece 702 to apply the flux 704. At this time, in some cases, a flux application check is performed prior to application. For example, when preset, for example, when the assembly of parts 14 to a series of base materials 12 is started, or when a set time has elapsed since the previous application check, the assembly of parts 14 to a set number of base materials 12 is performed. The flux application check is performed when the process is performed. In the flux application head 38, the dispenser nozzle 116 is moved to a position where the dispenser nozzle 116 is positioned on the container 552 of the flux check unit 500, and the flux discharge operation is performed a predetermined number of times by the dispenser nozzle 116, and the flux is discarded. Done.

  Next, the dispenser nozzle 116 is moved above a portion of the sheet 502 supported by the sheet support base 510 and is lowered to a position close to the sheet 502 to apply a flux onto the sheet 502. Application is performed by changing the position and the number of times set in advance. After the application, the sheet 502 is imaged by the imaging device 42, and whether or not the flux is normally discharged from the dispenser nozzle 116 is checked based on whether or not a predetermined flux image is obtained. If an image of a predetermined flux is not obtained and the flux is not properly discharged, it is abnormal, and the notification device 666 notifies the occurrence of the abnormality. If an appropriate flux image is obtained, the flux can be applied by the dispenser nozzle 116, and the flux 704 is applied to the solder film piece 702. At this time, the movement position of the flux application head 38 is corrected based on each position error in the X-axis and Y-axis directions of the part assembly location, and application is performed with high positional accuracy. After the application of the flux 704, the transport head 36 is moved, the component holder 130 is moved onto the component assembly location and lowered, and the held component 14 is placed on the flux 704.

  As is clear from the above description, in this embodiment, the electromagnetic direction switching valve 482 constitutes a negative pressure control device, and the part that controls the electric motor 376 of the individual control device 660 constitutes a cutting length control device. ing. Further, the head moving device 40 constitutes a relative moving device that relatively moves the work heads 36 and 38 and the base material conveyance holding device 32 in three directions orthogonal to each other. The relative movement device includes a parallel direction movement device that moves the work heads 36 and 38 and the base material conveyance holding device 32 in a direction perpendicular to the axis of the attachment holder 130 and parallel to the horizontal plane; A vertical direction moving device that moves in a direction perpendicular to the plane, but the relative moving device may include only a parallel direction moving device.

  Note that the application of the flux to the base material and the placement of the solder film pieces are performed in two different assembly machines, for example, in an upstream assembly machine among two adjacent machines, Application of the flux on the film piece and mounting of the parts may be performed in an assembly work machine on the downstream side.

  Further, the feeder holding base may be provided in the work machine main body.
