The mounting head 6 will be described later with reference to FIG.
The transport device 2 positions and fixes the printed circuit board P to the positioning portion at the substantially center by a positioning device (not shown).

  The component supply devices 3A and 3B are arranged at the back side position and the near side position of the transport device 2, and a large number of component supply units 8 are arranged side by side on the feeder bases of the cart bases 7A and 7B as mounting bases. is there. Each cart base 7A, 7B is detachably disposed on the apparatus main body via a connector so that the tip on the component supply side of the component supply unit 8 faces the conveyance path of the printed circuit board P, and each cart base 7A, When 7B is properly attached to the apparatus main body, power is supplied to the component supply unit 8 mounted on the cart bases 7A and 7B, and when the handle is released and the handle is pulled, the structure can be moved by a caster provided on the lower surface. It is.

  The pair of front and rear beams 4A and 4B that are long in the X direction are guided by a Y-direction moving drive source 15 (FIG. 4) constituted by each linear motor along a pair of guides (not shown) extending in the front and rear. Sliders (not shown) fixed to the beams 4A and 4B slide and individually move in the Y direction.

  The beams 4A and 4B are respectively provided with the mounting heads 6 that move along guides in the longitudinal direction (X direction) by an X-direction moving drive source 16 (FIG. 4) constituted by a linear motor. The X-direction moving drive source 16 includes a pair of front and rear stators (not shown) fixed to the beams 4A and 4B, and a movable member (not shown) provided between the stators and provided on the mounting head 6. Is done.

  Accordingly, the mounting heads 6 are provided inside the beams 4A and 4B so as to face each other, and the mounting head 6 on the back side takes out an electronic component from the component supply unit 8 of the corresponding component supply device 3A on the back side. The front mounting head 6 can take out an electronic component from the corresponding front-side component supply device 3B and mount it on the printed circuit board P.

  Each mounting head 6 is composed of a head mounting body 6A as a fixed portion and a rotating body 6B having a cylindrical shape and a circular shape in plan view, and is movably mounted on the beams 4A and 4B via the mounting member 6C. It is done. The rotating body 6B can be rotated about a vertical axis by a θ-axis drive source 17, and suction nozzles 5 as component holders are concentrically centered on the rotating center at the periphery of the rotating body 6B. A plurality of lines are arranged at predetermined intervals. The suction nozzle 5 can be moved up and down by a vertical axis drive source 18, the electronic component D is taken out from the component supply unit 8 by vacuum suction, and the electronic component D taken out on the printed circuit board P is mounted by stopping the vacuum suction. To do. The rotating body 6B rotates with respect to the mounting head 6 and the head mounting body 6A which is a fixed portion.

  Here, the component supply unit 8 feeds the storage tape T, which is sequentially wound in a state of being wound around a supply reel (not shown) rotatably mounted on the cart bases 7A and 7B, by a predetermined pitch by driving a sprocket (not shown). The storage unit 50 that stores the electronic component D is stopped at the component supply position (component extraction position) (see FIG. 2). That is, a tape feeding mechanism that intermittently feeds the storage tape T to the take-out position of the electronic component D by rotating a feed sprocket whose teeth are fitted in feed holes opened at predetermined intervals in the storage tape T, And a cover tape peeling mechanism for peeling the cover tape covering the upper side from the carrier tape below the storage tape T just before the supply position by driving the peeling motor. The carrier tape is peeled off by the cover tape peeling mechanism. The electronic parts D loaded in the storage section 50 (opened at a predetermined interval (the above-mentioned predetermined pitch) in the feeding direction of the storage tape) are sequentially supplied to the component supply position.

  In addition, each component recognition camera 10 picks up an image of the electronic components D sucked and held by the suction nozzles 5 provided in the respective rotating bodies 6B from the lower side before being mounted on the printed circuit board P. This imaging is performed by irradiating illumination from an illumination unit (not shown) provided around the recognition camera 10 onto the electronic component D held by the suction nozzle 5 and capturing the reflected image. This reflection image captures an image of a part that reflects illumination such as a lead of the electronic component D, and since the background is misrecognized as a part that easily reflects the illumination, the background is made dark. Yes. For example, the lower end surface of the suction nozzle 5 and the lower portion of the mounting head 6 (including the lower surface of the rotating body 6B) that is the background are painted black (see FIG. 2).

  Hereinafter, the mounting head 6 will be described in detail with reference to FIGS. 2 and 3. First, as described above, the mounting head 6 can be moved in the XY direction (horizontal direction) by the X-direction moving drive source 16 and the Y-direction moving drive source 15, and the rotating body 6B is connected to the head mounting body 6A by a servo motor. Is supported rotatably by a θ-axis drive source 17.

  Reference numeral 20 denotes a take-out position imaging camera (hereinafter referred to as an imaging camera) that includes a telecentric lens 21 and an imaging element 22 that do not change the size of an image of an object to be imaged and is fixed to the head mounting body 6A via the mounting body 23. It is said.)

  The mounting head 6 is provided so as to be movable with respect to the beams 4A and 4B without changing the height position. However, the suction nozzle 5 arranged at the same distance with respect to the rotation center of the rotating body 6B is the rotating body 6B. Is moved to a predetermined rotation position (position at 9 o'clock in FIG. 3 closest to the beam 4; hereinafter referred to as an extraction rotation position). The suction nozzle 5 positioned at the take-off rotation position descends from the mounting head 6 and vacuum-sucks the electronic component D positioned at the position (component supply position) where the electronic component D of the component supply unit 8 positioned immediately below is supplied. However, the position of the upper surface of the component placed at the component supply position of the component supply unit 8 vertically below the extraction rotation position is set as the component extraction position. The part removal position is a predetermined position in the plane direction and the vertical direction.

In this embodiment, the component supply unit 8 accommodates the electronic component D on the tape T. However, there may be a component supply apparatus in which the component supply unit 8 is mounted on a planar tray at a predetermined pitch in the XY direction.
The imaging camera 20 is attached to the mounting head 6 so as to be able to image the take-out position of this component. When the suction nozzle 5 at the take-out rotation position is located immediately above the supply position of the electronic component D of the component supply unit 8, the imaging camera 20 can take an image of the electronic component D located at the take-out position of this component from obliquely above.
The height of the upper surface of the electronic component D placed at the component takeout position is based on a predetermined height, and when the height of the upper surface changes depending on the thickness of the component, the plane direction of the component takeout position Change the reference position. When the electronic component D is mounted on the printed circuit board P, the mounting position is imaged by the camera 20 and recognition processing is performed. If the upper surface height of the printed circuit board P is different from the height of the upper surface of the reference electronic component D described above. Similarly, the reference position in the plane direction of the component mounting position is changed. The height position of the surface of the electronic component D and the height position of the surface of the tape T are considered to be substantially the same.
Reflected light from the electronic component D positioned at the component take-out position and the storage unit 50 for storing the electronic component D is reflected by the mirror 51 and guided to the imaging camera 20 through the telecentric lens 21 and irradiated. An image sensor 22 is provided for exposure. By this exposure, an image of the electronic component D and the storage unit 50 that stores the electronic component D is formed on the imaging element 22. A CMOS or a CCD can be employed for the image sensor 22.
An LED 30 for illumination is attached to a side surface of the imaging camera 22 that captures light to be imaged. The LED 30 is turned on to illuminate the position where the component is taken out, and reflected light from the electronic component D is captured by the imaging camera 22. From the LED 30 to the component take-out position, ie, the component at the component supply position of the component supply unit 8, the brightness for obtaining a sufficiently recognizable image can be obtained if it is about 10 mm to 20 mm. The front surface of the LED 30 (the image capturing surface on the right side of the imaging camera 20 in FIG. 2) is covered with a transparent cover, but this portion becomes brighter when illuminated with the illumination light of the component recognition camera 10. 5, and the protruding vertex is positioned on the left side of the rotating body 6 </ b> B as a background when the electronic camera D is imaged by the component recognition camera 10.
The LED 30 may be provided at any position on the lower surface of the mounting head 6, but in order to darken the background of the suction nozzle 5, it is better not to provide it near the suction nozzle.
The imaging camera 20 allows an axis perpendicular to the plane of the imaging element 22 and passing through the central axis of the telecentric lens 21 to pass through the take-out rotation position in plan view as shown in FIG. It is good to provide in the position which becomes parallel to the feed direction of T. At this position, the suction nozzle 5 that is not in the take-out rotation position can be positioned closer to the suction nozzle in the take-out rotation position (can be located at least not apart), and its axis is vertical. The angle formed with the axis can be made as small as possible. Although the electronic component D is imaged obliquely from above, it can be imaged from a position closest to the top, and the center of the screen can be set to the component extraction position, so that the image can be accurately recognized.

However, the position of the storage unit 50 is recognized if the center position of the storage unit 50 at the component take-out position (component supply position of the component supply unit 8) is not necessarily at the center of the imaging screen but is within the screen. I can. Preferably, all the images of the storage unit 50 are shown on the screen.
Since the electronic component D attracted by the suction nozzle 5 has a certain size, the angle with respect to the vertical direction of the light beam taken in from the component take-out position by the imaging camera becomes a certain amount, and an image viewed obliquely from above is obtained. I will take an image. In particular, a step is provided on the suction nozzle 5 side below the imaging camera 20 so as not to interfere when a large component D is picked up.

  The imaging camera 20 is a head in which the plane of the imaging element 22 faces the position when the take-out rotation position of the suction nozzle 5 is not at 9 o'clock in FIG. 3 but at another position (for example, at 3 o'clock, 12 o'clock or 6 o'clock). What is necessary is just to provide in the closest position of 6 A of attachment bodies. Or even if it becomes far, it may be provided at another position of the attachment body 6A so that the picking position of the component by the suction nozzle 5 can be imaged.

  As shown in FIG. 1, a substrate recognition camera 55 is provided on the beam 4 side of the head mounting body 6 </ b> A of the mounting head 6. The board recognition camera 55 takes an image of a vertically lower position, and takes an image of a positioning mark for the printed board P.

  Next, a description will be given based on the control block diagram of FIG.

  25 is a control device that performs overall control of operations related to mounting of the electronic component D of the electronic component mounting device 1, a determination device that performs various determinations, a comparison device that performs various comparisons, a control device such as an execution device, Mounting data including mounting coordinate information including the X direction, Y direction and angular position in the printed circuit board P in the order of electronic component mounting step numbers (for each mounting sequence), mounting data including the layout number information of each component supply unit, and the component supply unit A storage unit (storage device) for storing component placement position data relating to the component ID for each of the arrangement numbers, component library data including electronic component size data, thickness data, and the like for each electronic component.

  Based on the data stored in the built-in storage unit, the control device 25 rotates the θ-axis drive source 17 that rotates the rotating body 6B, the X-direction movement drive source 16 and the Y-direction movement drive source 15 of the mounting head 6, and the suction. The driving of the nozzle vertical axis drive source 18 and the like of the nozzle 5 is controlled.

  Reference numeral 28 denotes a recognition control circuit connected to the control device 25. The recognition control circuit 28 accommodates the electronic component D positioned by the imaging camera 20 at the component supply position (component extraction position of the suction nozzle 5) by the component supply unit 8 and the electronic component D. The image data obtained by imaging the storage unit 50 to be received is received, or the image data is recognized based on an instruction from the control device 25.

  Hereinafter, taking-out and mounting operations of electronic parts will be described.

  When the operator presses the operation start switch portion of the touch panel switch of the operation portion (not shown), the printed board P is carried from the upstream device to the positioning portion of the electronic component mounting device 1 and the positioning operation is started by the positioning mechanism.

  The control device 25 then mounts the electronic component according to the mounting data in which the XY coordinate position, the rotation angle position about the vertical axis, the arrangement number, and the like to be mounted on the printed circuit board P stored in the storage unit are designated. The electronic component D to be mounted by the suction nozzle 5 of each mounting head 6 of the apparatus 1 is controlled so as to be sucked and taken out from each component supply unit 8.

  That is, first, in the component supply unit 8 for supplying the electronic component D, the feeding operation of the electronic component D to the component supply position is performed, and the storage unit 50 for storing the electronic component D at the component supply position stops positioning. In parallel, the mounting head 6 moves in the X and Y directions along with the movement of the beam 4, and the suction nozzle 5 at the take-out rotation position is located in the component supply unit of the component supply unit 8. Move up and stop.

Next, the LED 30 is momentarily turned on for a short time to illuminate the component take-out position, and the image pickup element 22 of the image pickup camera 20 located obliquely above the storage portion 50 has the storage portion 50 and the electronic component D shown in FIG. An image as shown in FIG. This image is transferred to the recognition control circuit 28. Based on this image, the position between the component extraction position (in this case, the upper surface of the electronic component D is at the reference height and the component extraction position is positioned at the center of the screen) and the center position of the storage unit 50. Misalignment is recognized.
Since the telecentric lens 21 is used, the horizontal dimension of the image is not corrected, and the vertical dimension (feeding direction of the storage tape T) is an image taken from an oblique direction. Corrections can be made. The mounting head 6 moves in the X and Y directions in order to correct the recognized positional deviation amount, but the suction nozzle 5 starts to descend after the correction movement and sucks the electronic component D.
If the correction movement in the XY direction is finished while the suction nozzle 5 is lowered, the lowering operation and the XY correction movement operation may be performed in parallel. In this way, the suction nozzle 5 is lowered as shown in FIG. 6, and the center position of the electronic component D can be sucked and taken out.

  Alternatively, when the control device 25 determines that the positional deviation in the XY direction recognized from the imaging screen of the imaging camera 20 is within an allowable range that does not cause any problem even if the component D is picked up as it is, it is in the XY direction (horizontal direction). The electronic component D is adsorbed by lowering the adsorbing nozzle 5 without performing the correction movement of the mounting head 6. Based on the captured image, not only the position of the storage unit 50 but also the positional deviation of the electronic component D itself may be recognized.

  When the upper surface state of the imaged electronic component D is recognized and it is determined that there is a scratch or a chip, the electronic component D is discarded without being attached to the printed circuit board P after being sucked. Alternatively, without storing such an electronic component D, the storage tape T may be fed by one pitch and the next storage unit 50 may be positioned at the component supply position. When the electronic component D is recognized as a different electronic component D from the recognition result of the electronic component D, the size difference, the mark indicating the component type, or the character specified by the mounting data, the abnormal display is mounted on the monitor (not shown). The operation may be stopped.

  Further, it is possible to determine whether or not the electronic component D is stored in the storage unit 50 from the captured image of the storage unit 50 of the imaging camera 20, and when the electronic component D is not stored, the electronic component D is taken out. It is possible to stop the lowering of the suction nozzle 5 so that it does not occur, and to send the next storage unit 50 to the part removal position. Alternatively, even if the suction operation by the suction nozzle 5 is performed, it is possible to determine in advance that there is no component and perform processing so that the electronic component D is not counted as a suction error.

  In this way, each time the plurality of suction nozzles 5 of the mounting head 5 are moved to the component supply position of the component supply unit 8 for supplying the electronic component D to be taken out and stopped, the electronic component D becomes the component supply unit 8. After stopping at the component supply position, the imaging camera 20 captures an image of the component take-out position (that is, the component supply position of the component supply unit 8), and the above-described recognition processing and subsequent processing are performed.

The electronic component D held by all the suction nozzles 5 in the same mounting head 6 is judged to be a normal electronic component D, and the electronic component D that is stably suctioned is moved by the horizontal movement of the mounting head 6. It is moved onto the recognition camera 10.
All the electronic components D held by the plurality of suction nozzles 5 of the mounting head 6 are collectively imaged by the recognition camera 10, and the horizontal position of the mounting head 6 is recognized, and the positional deviation is corrected to correct the printed circuit board. The electronic components sucked by the suction nozzle 5 are sequentially mounted at positions where P should be mounted.
At this time, the electronic camera D picked up by the pick-up nozzle 5 at the pick-up rotation position is picked up by the imaging camera 20 when the LED 30 is turned on at the time of mounting, and is brought into an accurate position from the positional relationship with the pattern position of the printed circuit board P. The control device 25 can confirm whether it has been installed. Alternatively, the control device 25 determines whether or not the electronic component D is securely mounted by the imaging of the component take-out position below the suction nozzle 5 immediately before and immediately after the mounting, and the electronic component D is lifted without being mounted. Judgment can be made.

  Since only the suction nozzle 5 moves up and down without the mounting head 6 itself moving up and down, the imaging camera 20 can always take an image of the picking position of the component. However, when the mounting head 6 moves up and down, a predetermined position of the mounting head 6 is obtained. It is only necessary to control the lighting of the LED 30 and the exposure timing of the image sensor 22 so as to image the part extraction position at the height position.

  Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description, and the present invention is not limited to the various embodiments described above without departing from the spirit of the present invention. It encompasses alternatives, modifications or variations.
