Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a component mounting apparatus and a component mounting method for mounting an electronic component on a circuit board. More specifically, the present invention relates to a discarding device for collecting discarded members such as used component supply tapes discharged after supplying components to the component mounting apparatus and components discarded without being mounted on the component mounting apparatus. The present invention relates to a member collecting device, a component mounting device provided with the discarded member collecting device, and a component mounting method for collecting discarded components by suction.
[0002]
[Prior art]
Components that mount electronic components and other mounted components in a tape form at equal intervals in order to continuously supply a large amount of various types of components to the component mounting device in response to the recent increase in the speed of component mounting devices. Supply tapes are widely used. After the component supply, the used component supply tape is cut into tape waste, and is generally sucked and collected by a tape waste collection device arranged near the component mounting device using negative pressure. Such tape waste collection processing has become important from the viewpoint of meeting recent demands for protection of the global environment, effective use of resources, and the like.
[0003]
On the other hand, even if the component is removed from the component supply tape by the mounting nozzle to perform component mounting, if it is determined that mounting the component is inconvenient for some reason, the component is not mounted on the circuit board. Is transported to a component disposal position by the mounting nozzle, and is discarded and collected in a disposal component collection box provided at that position. As an example where mounting a component is inconvenient, if the component is different from a predetermined component, if the held posture of the component is not in a state where it can be mounted normally, a part of the component has a defect. Is recognized. Since recent parts have high added value and most of the discarded parts are highly likely to be reused, protection of the global environment and effective use of resources are the same as in the case of tape scraps. In addition to the above, the recovery of discarded parts is extremely important from the viewpoint of economy.
[0004]
FIG. 10 shows an outline of the component mounting apparatus. In the figure, a component mounting apparatus 1 includes a component supply unit 2 that supplies components to be mounted, such as electronic components, to the component mounting apparatus 1, and a mounting head unit that sequentially extracts components from the component supply unit 2 and mounts the components on a circuit board 18. 4, a board holding section 6 for positioning and holding the circuit board 18 carried into the component mounting apparatus 1, and a control section 7 for controlling the operation of the entire component mounting apparatus 1.
[0005]
A plurality of component supply devices (hereinafter, referred to as “parts cassettes”) 11 prepared according to the types of components required for mounting are mounted on the component supply unit 2, and the corresponding component cassettes are synchronized with the mounting timing. 11 is conveyed to a position facing the component take-out position of the mounting head unit 4. Therefore, the component supply unit 2 on which the parts cassette 11 is mounted reciprocates in the X direction in FIG. On the other hand, the circuit board 18 carried into the component mounting apparatus 1 is positioned and regulated and held at a position facing the mounting nozzle moved to the component mounting position by the board holding unit 6. Thereafter, the mounting nozzle of the mounting head unit 4 holding the component descends toward the circuit board 18 and mounts the component at a predetermined mounting position.
[0006]
FIG. 11 shows main components of the component mounting apparatus 1 shown in FIG. The mounting head unit 4 in the center of the figure is formed of an index (hereinafter, referred to as “index 4”), and a plurality of mounting nozzles 13 are mounted on the index 4 at equal intervals in a circumferential shape. The index 4 makes an intermittent rotational movement in the direction of arrow 15 and sequentially transports each mounting nozzle 13 from the component pick-up position on the back side (right side) in the Y direction to the component mounting position on the near side (left side) in the Y direction. I do.
[0007]
The component supply unit 2 reciprocates in the X direction to sequentially transport and position the parts cassette 11 containing components to be mounted next to the component removal position. On the other hand, the substrate holding unit 6 is provided with driving devices 16 and 17 for transporting the circuit board 18 in both the X and Y directions, and positioning the circuit board 18 in both the X and Y directions to move the circuit board 18 to a predetermined mounting position. Enables mounting of components.
[0008]
After the component mounting, the mounting nozzle 13 moves in the direction shown by the arrow 15 by the further intermittent rotation of the index 4, returns to the component take-out position again, and repeats the above operation. After the parts cassette 11 has been supplied, another parts cassette 11 containing the parts to be mounted next is positioned at the parts take-out position. Therefore, the parts cassette 11 is conveyed to the parts supply unit 2 and left or right in the X direction in the drawing. Is transported and retreated.
[0009]
FIG. 12 shows an outline of a component supply tape 21 for supplying components to the component mounting apparatus 1. The component supply tape 21 is generally composed of a base tape 23 for accommodating the components 12 in a large number of recesses provided at regular intervals 22 and a top tape 24 for preventing the components 12 from falling off and further protecting the components 12 from intrusion. ing. The base tape 23 is usually formed of synthetic resin or paper, and has a plurality of transport holes 25 for driving the parts cassette 11 at regular intervals. The top tape 24 is generally formed of a thin synthetic resin film, and is conveyed while being adhered to the base tape 23 to protect the component 12.
[0010]
When supplying the components to the component mounting apparatus 1, the top tape 24 is peeled off from the base tape 23 immediately before the component take-out position. As a result, the upper part of the component 12 is opened, and the component 12 can be taken out by the mounting nozzle 13 (see FIG. 9). The component supply tape 21 configured as shown in the drawing is wound around a reel 26 and rotatably attached to the parts cassette 11 using an attachment hole 27.
[0011]
FIG. 13 shows a state in which the reel 26 shown in FIG. Each time the drive lever 31 is operated, the parts cassette 11 pulls out the component supply tape 21 from the reel 26, intermittently sends it out, and sequentially positions the components 12 at the component removal position 32. The transport at this time is performed by the teeth provided on the outer peripheral portion of the transport wheel 33 located at the left end of the parts cassette 11 meshing with the transport holes 25 (see FIG. 12) provided in the base tape 23. . By the pressing operation of the drive lever 31 by the component mounting apparatus 1, the transport wheel 33 is intermittently driven each time in the counterclockwise direction in the figure, whereby the component supply tape 21 is sequentially moved by a constant gap 22 (see FIG. 12). Move left.
[0012]
The top tape 24 of the component supply tape 21 is peeled off from the base tape 23 immediately before the component take-out position 32 as shown by a two-dot chain line in FIG. The drive of the top tape collecting reel 34 is also performed via the link mechanism by the pushing operation of the drive lever 31.
[0013]
Returning to FIG. 11, of the component supply tape 21 driven by the parts cassette 11 and supplying the components to the component mounting apparatus 1, the unnecessary portion after the component is taken out is disposed immediately below the component supply position. It is cut by the cutter 14. As described above, the component supply unit 2 needs to retract the used part cassette 11 from the removal position in preparation for the next component removal. At this time, since the unnecessary portion of the component supply tape 21 protruding toward the component mounting apparatus 1 after use becomes an obstacle to the retreat movement, the unnecessary portion is cut just before the retreat movement. The length of the tape scraps generated by cutting varies depending on the tape transport pitch (constant interval 22 in FIG. 12) per supplied part, but is usually about several mm to about 30 mm long.
[0014]
As a means for collecting the tape waste after the cutting, a tape waste collection device 35 as shown in FIG. 11 is known in the related art (for example, see Patent Document 1). According to the disclosed contents, in FIG. 11, a collection port (not shown) is opened immediately below the cutter 14 for cutting the component supply tape 21 of the component mounting apparatus 1, and the tape waste falls into the collection port. This collection port is connected via a hose 37 to a dust collector 36 of a tape waste collection device 35 arranged near the component mounting apparatus 1 (or may be inside the component mounting apparatus). Due to the suction action of the dust collector 36 utilizing the negative pressure, the tape scraps that have been cut and fallen into the collection port are conveyed into the dust collector 36 along the hose 37. A collection box (not shown) is mounted in the dust collector 36, and the tape waste is collected in the collection box. The attachment and detachment of the collection box is performed by opening and closing a lid provided at any position of the dust collector 36.
[0015]
Apart from the above, in the related art, a means for collecting the component 12 that has not been mounted for any reason as described above among the components picked up by the mounting nozzle 13 at the component picking position is taken (for example, See Patent Document 2.). The component 12 that has not been mounted is transported to the component disposal position set at any one of the stop positions during the intermittent rotation of the index 4 while being held by the mounting nozzle 13. As shown in FIG. 11, a component collection box 38 for collecting discarded components is provided at the component disposal position. When the suction operation of the mounting nozzle 13 stopped at this position is stopped, the held component 12 is released from the restraint of the mounting nozzle 13 and falls into the component collection box 38 to be collected.
[0016]
In the prior art, as a countermeasure for removing and collecting foreign matter adhering to the mounting nozzle 13, a device for applying a positive pressure to the mounting nozzle 13 and simultaneously applying a negative pressure from the outside to suck and collect the foreign matter. Is disclosed (for example, refer to Patent Document 3). Such deposits on the mounting nozzle 13 could not be separated from the mounting nozzle 13 even by the mounting operation of the mounting nozzle 13, and some kind of adhesive force exceeding the positive pressure applied to the mounting nozzle 13 during mounting works. It is assumed that Therefore, pressurized gas is injected to forcibly separate the adhered foreign matter from the mounting nozzle 13, and at the same time, suction by a negative pressure is required.

[Problems to be solved by the invention]
However, there is room for improvement in the above-described tape waste collecting apparatus and component collecting means according to the related art. First, in a tape waste collecting device 35 according to the related art as shown in FIG. 11, a collecting box dedicated to a dust collector is stored in a dust collector 36. This collection box is designed in accordance with the size of the dust collector 36, so that the production quantity naturally becomes small and the cost increases. In addition, the collection box needs to be kept in stock and managed separately from, for example, container containers used for transporting other parts, so that handling operations are complicated.
[0019]
Furthermore, it is necessary to ensure the airtightness of the entire dust collector 36 in order to effectively function the suction action of the dust collector 36 due to the negative pressure. In the related art, a complicated mechanism for securing the airtightness by closing the lid of the dust collector 36 after disposing the collection box inside the dust collector 36 is required. For example, a sealing material is attached to the lid of the dust collector 36 or the entire periphery of the main body side, and after closing the lid, a lever is tightened to secure sealing performance. Still, the sealing properties of the lid that opened and closed were unstable. Needless to say, not only the lid but also the entire dust collector 36 had to have a sealing property.
[0020]
On the other hand, when a collection box 38 according to the related art that collects components to be discarded without being mounted for some reason is used, the components 12 discarded from the mounting nozzle 13 may not fall properly into the collection box 38, or may be collected. Even if it falls into the box 38, there may be a problem that it jumps out of the collection box again due to the vibration of the apparatus or the like. If the protruding component falls onto the circuit board 18 during the mounting process, it may be captured by the solder paste applied to the circuit board 18 and the circuit board 18 may be defective.
[0021]
In the component mounting apparatus 1, in addition to the rotary type having the index 4 as shown in FIGS. 10 and 11, the mounting nozzle 13 is transported using an XY robot and mounted on the circuit board 18 whose positioning is regulated. There is an XY robot type. In the XY robot type component mounting apparatus, generally, a relatively large component (for example, several mm square or more) is often mounted, and the component itself has a certain mass. Tend to fall relatively directly below the collection box.
[0022]
On the other hand, in the rotary type component mounting apparatus 1 as shown in FIGS. 10 and 11, problems are likely to occur because small chip components are generally handled in many cases. For example, as typified by a 0603 chip component (0.6 mm × 0.3 mm size), recent small chip components are extremely minute and light, so that they are not only easily dropped directly below, but also in some cases, in the air. Floating could also occur. Further, in the case of the rotary type, the wind pressure changes easily due to the mounting nozzle 13 which turns and passes one after another in close proximity, and there is a possibility that components once collected in the collection box 38 are sucked out. In the component mounting apparatus of the XY robot type, there is a degree of freedom in disposing the component collection box away from the normal mounting position. However, in the case of the rotary type, the rotation trajectory of the index 4 is fixed. Is restricted within the turning range of the index 4.
[0023]

[0037]
In FIG. 1, the cover 63 of the suction unit 60 is shown in an open state, and the suction filter 64 can be seen inside the suction unit 60. When a negative pressure is generated by the action of the electric blower 61 rotating behind the suction filter 64, for example, discarded members such as tape scraps are sucked by the suction duct 62 and sucked into the suction unit 60. Discarded members such as tape waste are blocked by the suction filter 64 and fall into the collection box 40 disposed below without reaching the electric blower 61. Here, the electric blower 61 is used to generate a negative pressure, but it is also possible to use a reciprocating negative pressure generator or to connect to an external negative pressure supply source.
[0038]
Next, a box-shaped collection box 40 having an open upper end is shown on the left side of FIG. The collection box 40 does not need to be specially designed for collecting waste materials as in the prior art. A versatile commercially available container that can be used to carry in various components from a supplier can be used. Generally, a general-purpose container container is formed of a synthetic resin, and a number of reinforcing ribs protruding outward as shown in the figure are provided around the container so as to withstand a predetermined heavy object conveyance.
[0039]

Also, a number of ribs extending in the vertical direction are provided immediately below the top rib 41, and these ribs further extend in the horizontal direction below the top rib 41, and are connected to the outer peripheral rib 42 that goes around the outer periphery. The presence of these reinforcing ribs guarantees a strength sufficient to withstand the top box 41 and the outer peripheral box 42 even when the collection box 40 is lifted together with the internal storage items.
[0040]
FIG. 2 shows a state viewed from the side of the tape collecting device 50 shown in FIG. In the drawing, the attachment / detachment mechanism 59 located on the back side except for one side frame 56 located on the front side is displayed. In the figure, an attachment / detachment mechanism 59 includes an operation lever 71, an elevating plate 72 that moves up and down by rotating the operation lever 71, and swings the elevating plate 72 in a direction perpendicular to the drawing in accordance with the elevating plate 72 moving up and down. It is mainly composed of a holding bracket 73 and a guide plate 74 for regulating the elevating operation of the operation lever 71. The operation lever 71 is coupled to the other operation lever 71 located on the near side (not shown) by a handle bar 58 (see FIG. 1), and the operation of the pair of attachment / detachment mechanisms 59 is synchronized.
[0041]
In order to support the rotation of the operation lever 71 by operating the handlebar 58, the operation lever 71 includes a first support pin (hereinafter, referred to as a "vertical movement pin") 76 and a second support pin (hereinafter, "horizontal movement pin"). 78). Rollers 77 and 79 are rotatably supported by the two moving pins 76 and 78, respectively. On the other hand, the guide plate 74 fixed to the side frame 56 is provided with an inverted T-shaped slit 81. Among the slits 81, a roller 77 is fitted in a vertically extending groove, and a roller 79 is movably fitted in a horizontally extending groove. A stopper 82 for stopping the movement of the roller 79 at a predetermined position is fixed to the groove extending in the horizontal direction of the slit 81.
[0042]
The vertical moving pin 76 of the operation lever 71 penetrates the elevating plate 72 located behind the operating lever 71. Therefore, the elevating plate 72 moves up and down as the vertical moving pin 76 moves up and down. Conversely, the entire load applied to the elevating plate 72 is configured to be supported by the vertical movement pins 76. The lifting plate 72 is slidably supported by a guide plate 74 below and a holding bracket 73 that fits into a slit 83 provided in the lifting plate 72 itself above. A pair of claws extend from a holding bracket 73 located behind the elevating plate 72 and engage with the slits 83 to guide the elevating plate 72 so as to be able to move up and down.
[0043]
The upper end of the elevating plate 72 is bent toward the central space of the waste member collecting device 50, and forms a flange-like flange portion 84 extending in a direction perpendicular to the drawing. A holding bracket 73 that supports the upper part of the elevating plate 72 supports the flange portion 84 at the upper end of the elevating plate 72 so as to swing upward in the vertical direction in the drawing as the elevating plate 72 rises. When the flange portion 84 swings in a direction perpendicular to the drawing, the flange portion 84 enters and engages with the lower surface of the outer peripheral rib 42 of the collection box 40 shown by a two-dot chain line in FIG. enable. As a mechanism for swinging the elevating plate 72 held by the holding bracket 73 at the time of elevating and lowering, for example, means such as providing a slope in a direction perpendicular to the drawing with respect to the slit 83 of the elevating plate 72 can be considered.
[0044]
FIG. 3 shows a state in which the lower surface of the upper frame 57 of the waste member recovery device 50 is viewed from below. Parts below the lower part of the side frame 56 are omitted. In the figure, an opening 66 penetrating through the upper frame 57 itself is provided at a central portion of the upper frame 57, whereby a suction unit 60 located above the upper frame 57 and a space below the upper frame 57 are provided. And gas communication between them. When a negative pressure is generated in the suction unit 60 by the action of the suction unit 60 due to the presence of the opening 66, the inside of the collection box 40 (not shown) attached below the upper frame 57 is also maintained at the negative pressure.
[0045]
On the lower surface of the upper frame 57, a sealing material 67 formed in a rectangular shape with an elastic member such as rubber is attached. The shape of the sealing material 67 is provided so as to correspond to the rectangular shape of the plane of the top rib 41 (see FIG. 1) of the collection box 40, and both the sealing material 67 and the top rib 41 face each other. Thereby, the inside of the collection box 40 can be kept airtight.
[0046]
In FIG. 3, the elevating plate 72 disposed inside the above-described side frame 56, a holding bracket 73 that is fitted into the slit 83 of the elevating plate 72 from behind to support the elevating plate 72, and is formed at the upper end of the elevating plate 72 The outline of the flange portion 84 and the like is shown.
[0047]
The operation of the disposal member recovery device 50 configured as described above is as follows. First, the operator inserts the collection box 40 into the space at the center of the apparatus as shown by the two-dot chain line in FIG. At this time, the handlebar 58 of the attachment / detachment mechanism 59 and the operation lever 71 are located at the lower position indicated by the two-dot chain line in FIG. 2 and the entrance is opened, so that the collection box 40 can be easily inserted.
[0048]
Next, when the operator pulls up the handle bar 58 as shown by an arrow 75, the operation lever 71 rotates counterclockwise in the figure. At this time, among the vertical and horizontal moving pins 76 and 78 of the operation lever 71, the roller 79 fixed to the horizontal moving pin 78 is regulated by the horizontally extending groove of the slit 81 and moves rightward in FIG. I do. Due to the restricted movement of the roller 79, the roller 77 fixed to the vertical movement pin 76 moves upward along the vertically extending groove of the same slit 81. At the same time, the elevating plate 72 supported by the vertical movement pins 76 is lifted upward. When the elevating plate 72 is raised, the flange portion 84 at the upper end of the elevating plate 72 swings upward in a direction perpendicular to the drawing by the action of the holding bracket 73. As a result, the flange portion 84 enters the lower side of the outer peripheral rib 42 of the collection box 40 to support it, and further lifts it upward as the elevating plate 72 rises.
[0049]
When the operator raises the handle bar 58 to the position shown by the solid line in FIG. 2, the roller 79 supported by the horizontal movement pin 78 moves rightward from the position of the dead center (or conceived point) immediately below the vertical movement pin 76. The horizontal movement stops in contact with a stopper 82 which is arranged in advance at a position slightly shifted in the direction. The elevating plate 72 (and the collection box 40 supported by the elevating plate 72) reaches the highest position at the position of the dead center, that is, the position where the straight line connecting the vertical movement pin 76 and the horizontal movement pin 78 is orthogonal to the horizontal groove of the slit 81. Lifted (hereinafter referred to as "top dead center"). Therefore, at a position where the roller 79 has moved slightly to the right beyond the top dead center shown in FIG. 2, the roller 79 is stopped by the stopper 82 due to its own weight of the collection box 40 supported by the flange portion 84 of the elevating plate 72. To the right in the figure. As a result, a force for holding the handlebar 58 at the position where the handlebar 58 is pulled upward (a force for rotating the operation lever 71 in the counterclockwise direction) acts, so that the collection box 40 itself is also lifted. It is maintained in position and does not fall under its own weight.
[0050]
When the collection box 40 is in this raised state, the top rib 41 at the upper end of the collection box 40 is pressed against and held by the sealing material 67 shown in FIG. You. The collection box 40 is held at a position slightly lower than the highest position at the top dead center, but this slight downward movement can be sufficiently absorbed by the elasticity of the sealing material 67, and the airtightness can be improved. There is no problem. The force that presses the roller 79 toward the stopper 82 may include not only the own weight of the collection box 40 but also the reaction force generated by the top rib 41 pressing the sealing material 67 described above.
[0051]
When the electric blower 61 is started in the above state, a negative pressure is generated in the entire disposal member collection device 50 because the airtight state of the collection box 40 is ensured. As a result, discarded members such as tape scraps are sucked by the negative pressure through the hose 37 (see FIG. 11) connected to the suction duct 62 of the suction unit 60, and are collected in the collection box 40.
[0052]
When a predetermined amount of discarded members are collected in the collection box 40, the handlebar 58 is pushed down, and the operation lever 71 is rotated clockwise in the drawing, and the elevating plate 72 is lowered and collected. The sealed state of the box 40 is released. Further, the swing of the elevating plate 72 releases the engagement between the flange portion 84 and the outer peripheral rib 42 of the collection box 40, and the collection box 40 is lowered to the upper surface of the lower frame 55. When the handlebar 58 descends to the lowermost position, the exit of the central space is opened, and the collection box 40 is taken out and the collected waste material can be processed.
[0053]
The above-mentioned attachment / detachment mechanism 59 for maintaining the collection box 40 in the raised position is merely an example, and other types of mechanisms may be used. For example, a link-type mechanism or a cam-type mechanism can be used instead of the lever-type mechanism using the support pins 76 and 78, which are the two moving fulcrums described above. FIG. 4 shows an example of a detachable mechanism 59A using a link mechanism. In FIG. 4A, the operation lever 71 is rotatably fixed to a frame 51 (not shown) by a support pin 78A. One end of a link 80 is rotatably attached to the operation lever 71 by a support pin 76A, and the other end of the link 80 is rotatably attached to a lifting plate 72 by a support pin 86. The elevating plate 72 is held by a guide plate 74 (not shown) and a holding bracket 73 (see FIG. 2) so as to be movable up and down.
[0054]
Now, when the handlebar 58 is pulled upward as shown by the arrow 75, the operation lever 71 rotates counterclockwise in the figure around the support pin 78A toward the position shown by the broken line. As a result, the link 80 rotates clockwise about the support pin 86, and simultaneously pushes up the elevating plate 72 supported by the support pin 86 to reach the state shown in FIG. 4B. The elevating plate 72 is lifted to the highest position when the three support pins 76A, 78A, 86 are aligned (top dead center), and the link 80 abuts the stopper 82A at a position slightly beyond the top dead center. And stop. In this state, a force for rotating the collection lever 40 counterclockwise in the drawing acts on the operation lever 71 due to the load of the collection box 40 applied to the elevating plate 72 and other loads. Hold. Conversely, in order to release this sealing state, the handlebar 58 is depressed downward, whereby the operation lever 71 is rotated clockwise in the figure, and the link 80 is moved beyond the top dead center as shown in FIG. Return to the state shown.
[0055]
In the attaching / detaching mechanisms 59 and 59A shown in FIGS. 2 and 6, the collection box 40 is held by pulling the handlebar 58 upward from a position close to the floor. In order to reduce the burden on the worker at this time, it is also possible to hold the collection box 40 by pressing the handle bar 58 downward from above, and FIG. 5 shows an example of such a detachable mechanism 59B. ing. The basic configuration is the same as that of the attachment / detachment mechanism 59A shown in FIG. In FIG. 5A, the operation lever 71 is rotatably fixed to a support pin 78A, and the link 80 is rotatably attached to the operation lever 71 and the elevating plate 72 by two support pins 76A and 86, respectively.
[0056]
When the handlebar 58 is pushed downward as shown by the arrow 75A, the operation lever 71 rotates clockwise in the drawing toward the position shown by the broken line, and at the same time, the link 80 rotates counterclockwise around the support pin 86. 5 (b) by moving the elevating plate 72 upward. The link 80 abuts the stopper 82A at a position slightly beyond the top dead center where the three support pins 76A, 78A, 86 are aligned, and stops, and the attachment / detachment mechanism 59A holds the collection box 40 airtight in this state. I do. In order to release the sealing state, the handlebar 58 is pulled upward, whereby the operation lever 71 rotates counterclockwise in the figure, and the link 80 moves beyond the top dead center as shown in FIG. Return to the state shown in FIG.
[0057]
In the state shown in FIG. 5A, since the handlebar 58 is located above the upper end of the collection box 40, it is easy to take out the collection box 40 from the disposal member collection device 50. Further, the worker does not need to bend down to operate the handle bar 58 near the floor, and the burden on the operation is reduced. However, in this case, the handlebar 58 may be lowered by its own weight in the state shown in FIG. In order to prevent this, for example, a return spring 95, which is arranged so as to cross the support pin 78A during the rotation of the operation lever 71, is provided, or the handlebar 58 is stopped at the raised position (not shown). This can be easily dealt with by providing a simple lock mechanism.
[0058]
According to the waste member collecting apparatus according to the related art, it is necessary to carry out operations such as loading the collection box into the dust collector, closing a door serving as a takeout port, and tightening a fixing knob to maintain a vacuum. At this time, since a door-type hermetic seal was required, the sealing property was not necessarily sufficient. According to the disposal member collection device of the present embodiment, the collection box 40 can be attached and detached by a one-touch operation by vertically moving the handlebar 58, and at the same time, a sealed state can be reliably obtained by this operation. Further, the sealing state of the disposal member collection device 50 during the operation of the component mounting apparatus 1 can be easily confirmed by visually confirming the position (height) of the handlebar 58.
[0059]
A general-purpose container container can be used for the collection box 40, and the collection box 40 can be prepared at a much lower price than a dedicated product. Moreover, since it is versatile, it is not necessary to manage it individually, and it can be handled together with a container for transporting parts.
[0060]
In the above description, an example was described in which the tape scraps of the component supply tape cut after use were collected, but the disposal member collection device 50 according to the present embodiment is not limited to this, and may be mounted. It can also be used to collect parts that are discarded without being used. That is, one end of a component suction hose is fixed through the bottom surface of the component collection box 38 shown in FIG. 11 according to the related art, and the other end of the hose is fixed to the suction duct 62 of the waste member collection device 50. Accordingly, it is possible to positively suck and collect the discarded parts that have only been discarded. As a result, it is possible to prevent the parts from being scattered due to inadequate waste collection, thereby maintaining and improving the working environment, eliminating the cause of the failure of the circuit board, and promoting the effective use of the waste parts. The collection of waste components by suction is particularly advantageous in a rotary type component mounting apparatus that mounts fine components.
[0061]
For the purpose of collecting components that are discarded without being mounted, for example, a conventional collecting device (a dust collector 36) as shown in FIG. 11 can be used. However, it is more advantageous to use the disposal member recovery device 50 according to the present embodiment having many advantages as described above. In this case, since the components are generally finer and lighter than the tape scraps, the capacity of the collection device can be made smaller, and the general-purpose container used as the collection box is also smaller. It can be.
[0062]
Next, a waste member collecting device according to a second embodiment of the present invention will be described with reference to the drawings. FIG. 6 shows an overall outline of a disposal member recovery device 50A according to the present embodiment. The drawing shows a state in which the collection box 40 is inserted into the space of the central portion of the disposal member collection device 50A, and the handlebar 58 is pulled up and fixed in a sealed state. The same components as those of the first embodiment are denoted by the same reference numerals, and the following description focuses on the differences.
[0063]
In FIG. 6, a second suction duct 85 is additionally provided in the disposal member recovery device 50A according to the present embodiment in addition to the disposal member recovery device 50 of the previous embodiment. Thus, using one disposal member collection device 50A, the first collection duct 62 collects, for example, tape waste, and the added second suction duct 85 collects, for example, the waste component 12 at the same time. Can be done with As described above, sucking and collecting components that are discarded without being mounted is advantageous in avoiding scattering of components. However, providing a separate device for collecting components in addition to the tape scrap collecting device occupies extra floor space, impairs workability, and is uneconomical. In the disposal member collection device 50A according to the present embodiment, it is possible to collect both of them with a common device.
[0064]
In FIG. 6, the two suction ducts 62 and 85 provided in the disposal member collection device 50A are both connected to the collection box 40 via the suction unit 60A. In the illustrated example, the first suction duct 62 is used for collecting tape debris, and the second suction duct 85 is used for collecting discarded parts. Therefore, a hose 37 (see FIG. 11) for sucking tape dust is connected to the first suction duct (hereinafter, referred to as “tape dust suction duct”) 62, and the newly added second suction duct (see FIG. 11). The component suction duct 85 is connected to one end of a hose (not shown) that connects the component collection box 38 of the component mounting apparatus (see FIG. 11).
[0065]
If only the tape waste and the waste part are to be sucked and collected at the same time, it is only necessary to connect both the suction ducts 62 and 85 to the collection box 40. However, in this case, both of the waste members are mixed and collected in the collection box 40. In view of the processing after the collection, collection of such mixed waste members is not always preferable. The suction unit 60A according to the present embodiment is provided with a mechanism capable of separating and collecting both waste members for this purpose.
[0066]
FIG. 7 shows the inside of the suction unit 60A as seen through from the near side in the Y direction of FIG. The lower portion of the entire device below the frame portion 51 is the same as that according to the first embodiment shown in FIGS. In FIG. 7, the component collection duct 85 is mounted on the right side of the suction unit 60A so as to protrude outside alongside the tape dust suction duct 62. Inside the suction part 60A, a collection container fixing part 87 is formed at the end of the component suction duct 85, and a collection container 88 is detachably attached to the collection container fixing part 87. The outer peripheral portion of the collection container 88 is formed of a mesh member, and the mesh member can select a mesh according to the size of a component to be sucked. For example, even a fine component such as a 0603 chip component can be captured in the collection container 88 by selecting a mesh member having a finer mesh. In order to support the collection container fixing portion 87, an L-shaped support bracket 92 is newly provided in the suction portion 60A.
[0067]
The operation of the disposal member collection device 50A configured as described above is similar to that described in the previous embodiment in that the collection box 40 is fixed below FIG. 7 and the electric blower 61 (behind the suction filter 64). Is activated, a negative pressure is formed inside the suction part 60A. By the suction effect of the negative pressure, the cut tape waste is sucked from the tape waste suction duct 62 and the discarded component is sucked from the component suction duct 85 into the suction part 60A. Among them, the tape waste is dropped and collected from the suction part 60A into the collection box 40 located further below because the tape waste suction duct 62 is directly opened inside the suction part 60A. On the other hand, the discarded component sucked from the component suction duct 85 is captured by the mesh member of the collection container 88 through the collection container fixing portion 87 and collected in the container 88.
[0068]
The tape waste collected in the collection box 40 is pulled out of the apparatus together with the collection box 40 by pulling down the handle bar 58 as described in the previous embodiment, and is subjected to the collection processing. Further, the waste components collected in the collection container 88 are collected by removing the collection container 88 from the collection container fixing portion 87. The collection container 88 can be easily removed by opening a cover 63 (not shown) (see FIG. 1) provided above the suction unit 60A. With the above configuration, it is possible to separate and collect the tape waste and the discarded component.
[0069]
According to the disposal member recovery device 50A according to the present embodiment, by using a single device, tape waste and components can be recovered simultaneously without sacrificing floor space, and environmental protection and resource conservation can be achieved. Promote reuse. For the collection of parts, unlike the case of simply dumping from the mounting nozzle according to the conventional technology, the collection efficiency can be improved by suctioning using a negative pressure, and the failure of the circuit board due to the scattered parts Can be eliminated.
[0070]
Since the duct for sucking the parts in addition to the suction of the tape waste is provided, a problem of an increase in the capacity of the electric blower 61 of the disposal member collecting device 50A may occur. However, in the rotary type component mounting apparatus 1 in particular, many components to be mounted are generally fine, and the suction port opened at the component disposal position also has, for example, a circular shape having a diameter of about 20 mm or a rectangular shape having a size of about 20 mm × 30 mm square. It can be small in shape and the like. For this reason, even if the component mounting apparatus is provided with an opening for component suction, the influence on the negative pressure is generally small, and the capacity of the electric blower 61 is not required to be increased, or even if required, it is very small. It is something.
[0071]
In the example shown in FIG. 7, tape scraps that are normally collected in large quantities are collected on the side of the large-capacity collection box 40, and discarded parts that are usually small in number and particularly fine are collected in a small-capacity collection container 88. , But is not limited to this. If necessary, the capacity of the collection container 88 is increased to collect the tape waste here, and especially when a large component is mounted, the discarded component may be collected in the collection box 40. . Also, the means for separating and collecting the two is not limited to the collection container 88 as shown in FIG. 7. For example, the inside of the collection box 40 is divided into two, and the discharge port of the tape dust suction duct 62 is Other means may be used, such as a configuration in which the component suction duct 85 is opened toward one of the compartments, and the component suction duct 85 is opened toward the other compartment.
[0072]
Next, a waste member collecting device according to a third embodiment of the present invention will be described with reference to the drawings. Tape debris and components leaked from the component mounting device may be scattered around the component mounting device.Otherwise, dust floating in the facility may fall on the floor surface and leave the work environment if left unattended. make worse. In such a case, it is common for an operator to bring a vacuum cleaner for cleaning. Maintenance of the working environment by cleaning the floor surface is preferable from the viewpoint of ensuring workability and safety, and also from the viewpoint of maintaining the quality of products as precision parts or avoiding the occurrence of defective products.
[0073]
In general, a vacuum cleaner is stored somewhere in the facility so that an operator can clean around the mechanical equipment. When cleaning is required, the worker goes to a storage location in the facility to pick up the vacuum cleaner, and returns the vacuum cleaner to the original place after the cleaning work is completed. Normally, a common vacuum cleaner is prepared for a plurality of devices. Therefore, when the use timings of a plurality of devices are duplicated, an extra man-hour is required, such as a worker going to pick up again. In the present embodiment, a waste member collecting device capable of solving such a problem is provided.
[0074]
FIG. 8 shows a waste member collecting apparatus according to the present embodiment. In the figure, in the disposal member recovery device 50B according to the present embodiment, a third suction duct 91 that can be used for cleaning or the like is additionally provided in the suction unit 60B. One end of a cleaning hose (not shown) can be attached to the suction duct 91, and a suction port for cleaning can be attached to the other end of the hose. Other configurations are the same as those of the disposal member recovery device 50A according to the second embodiment shown in FIG. 6, and the same components are denoted by the same reference numerals. Hereinafter, a description will be given focusing on differences from the waste member recovery device 50A according to the second embodiment.
[0075]
Cleaning around the mechanical equipment is usually performed at the end of work or at the time of machine stoppage such as during shift change. Therefore, it is not necessary to suck the tape scraps and components during this time, and it is preferable that the first duct 62 and the second duct 85 be closed in order to secure a sufficient suction force for cleaning. Conversely, during the operation of the component mounting apparatus, the third suction duct for cleaning (hereinafter, referred to as “cleaning suction duct”) 91 is closed in order to surely suck the tape dust and the components. Is preferred. The suction unit 60B of the disposal member recovery device 50B according to the present embodiment includes a switching mechanism that can switch between opening and closing in synchronization with the suction duct to be used.
[0076]
FIG. 9 shows the inside of the suction unit 60B as seen through from the near side (left side) in the Y direction of FIG. The configuration of the other discarded member recovery devices 50B below the frame portion 51 is the same as that shown in the embodiments described above. In the figure, a suction section 60B is provided with three suction ducts 62, 85, and 91, and a switching mechanism 90 that can open and close these three suction ducts 62, 85, and 91 in an interlocked manner. The component suction duct 85 is supported by a bracket 92 inside the suction portion 60B, and is formed so as to be movable in the left-right direction indicated by an arrow 93. Due to the left and right movement of the component suction duct 85, the other terminal located inside the suction portion 60 </ b> B of the component suction duct 85 is slidably formed inside the collection container holding portion 87.
[0077]
A pin 96 is fixed to the component suction duct 85 in a direction extending perpendicular to the drawing. The pin 96 extends through the slit 94 extending in the lateral direction provided in the support bracket 92 to the front side in the figure, and supports one end of the connection bar 97 at the tip. The other end of the connecting bar 97 is fixed to a shutter plate 98 that opens and closes an opening of the cleaning suction duct 91. The shutter plate 98 is slidably supported in the groove of the mounting body 99 fixing the cleaning suction duct 91 to the suction portion 60B in the left-right direction in the figure, and opens and closes the cleaning suction duct 91 by this sliding movement. It is configured as follows.
[0078]
On the other hand, one end of a lever 101 is rotatably fixed to a pin 96 fixed to the component suction duct 85, and the other end of the lever 101 is connected to a cover plate 102 that opens and closes an opening of the tape dust suction duct 62. It is rotatably fixed. The cover plate 102 is rotatable around a support pin 103 fixed to the case of the suction unit 60B. In FIG. 9, a part of the bracket 92 is cut out so that the inside of the lever 101, the cover plate 102, and the like are displayed.
[0079]
The operation of the switching mechanism 90 configured as described above is as follows. First, when the component suction duct 85 is pulled out from the suction unit 60B along the right direction of the arrow 93, the terminal of the component suction duct 85 inside the collection container fixing unit 87 simultaneously slides rightward. Due to this movement, the positions of the two openings (not shown) which have been matched so far between the collection container fixing portion 87 and the component suction duct 85 are shifted, and thus, inside the collection container fixing portion 87, the component suction duct 85 Opening is closed.
[0080]
On the other hand, when the component suction duct 85 is pulled out from the suction portion 60B, the pin 96 moves rightward in the slit 94 at the same time, whereby the connection bar 97 is pulled rightward. As a result of this operation, the shutter plate 98 connected to the connection bar 97 also moves rightward, so that the cleaning suction duct 91 that has been closed is opened, and a suction operation using vacuum is enabled.
[0081]
Further, when the pin 96 moves to the right, the lever 101 fixed to the pin 96 presses the cover plate 102 to close the suction opening of the tape dust suction duct 62. FIG. 9 shows a state in which the component suction duct 85 is pulled out to the right, the cleaning suction duct 91 is opened, and the tape dust suction duct 62 and the component suction duct 85 are closed as described above.
[0082]
Conversely, when the component suction duct 85 is pushed in the leftward direction of the arrow 93 toward the inside of the suction portion 60B from the state shown in FIG. 9, the pin 96 moves inside the slit 94 to the left, thereby connecting the connecting bar 97. , The shutter plate 98 also moves to the left. With this movement, the shutter plate 98 closes the cleaning suction duct 91. On the other hand, similarly, by pushing the component suction duct 85, the tip of the component suction duct 85 enters the inside of the collection container fixing portion 87, and the openings (not shown) coincide with each other, so that the component suction duct 85 and the inside of the suction portion 60B are aligned. Conduct. At the same time, the movement of the pin 96 to the left pulls the lever 101 to the left, thereby rotating the cover plate 102 clockwise in the drawing, thereby opening the opening of the tape dust suction duct 62. As described above, the cleaning suction duct 91 is closed, and the tape dust and the waste component can be sucked in preparation for the operation of the component mounting apparatus.
[0083]
In the above example, the synchronized opening and closing of the suction ducts 62, 85, and 91 is performed by taking the component suction duct 85 in and out, but the synchronized opening and closing is not limited to this. For example, a handle may be provided on other movable parts such as the shutter plate 98 and the connection bar 97, and the cover 63 (see FIG. 8) of the suction unit 60B may be opened, and the handle may be operated to open and close each suction duct. good. Alternatively, the pins 96 and the shutter plate 98 may be extended to the outside of the suction unit 60B, and the extended portion may be operated from outside. However, it is preferable to use the component suction duct 85 which has already protruded to the outside as it is as a changeover switch, because it is not necessary to open and close the cover 63 or provide an extension of another component. Further, instead of the component suction duct 85, the tape dust suction duct 62 can be taken in and out, and the above-described switching mechanism 90 may be modified correspondingly.
[0084]
By using the disposal member recovery device 50B according to the present embodiment configured as described above, it is possible to always provide a device capable of cleaning near the equipment without preparing a separate vacuum cleaner for cleaning. And the burden on the operator can be reduced. Generally, cleaning is performed when the equipment is stopped. Therefore, by using the above-described switching mechanism, this device can be used exclusively for cleaning at the time of switching. At this time, the collection box 40 can be replaced, and the collection box 40 can be used separately for tape waste collection and cleaning. If desired, a garbage pack commercially available for a vacuum cleaner can be attached to the inside of the cleaning suction duct 91 (the inside of the suction section 60B), and the garbage is collected in the garbage pack and disposable. You can also. A commercially available component prepared for a vacuum cleaner may also be used for the cleaning suction duct 91 and the hose and suction port connected thereto.
[0085]
The embodiments of the waste member collecting apparatus according to the present invention have been described above. However, any combination of the component suction duct, the tape dust suction duct, and the cleaning suction duct may be arbitrarily selected. That is, a combination of a component suction duct and a cleaning suction duct, and a combination of tape dust suction and cleaning suction, which are not shown, may be provided in the suction unit 60. The switching mechanism can be appropriately changed according to these combinations.
[0086]
In the description of each of the above embodiments, the waste material collecting device is mainly used. However, the present invention also includes a component mounting device having these waste material collecting devices, and a device for sucking a waste component. It also includes a component mounting method for collecting components.
[0087]
