Description

  The present invention relates to a component supply apparatus equipped with a plurality of tape feeders.

  A component supply device equipped with a plurality of tape feeders is set in a component mounter, pitch-feeds the component supply tape drawn from the tape reel held by each tape feeder, and the top tape (cover tape) on the upper surface of the component supply tape ) Is peeled before the component suction position to expose the component in the component supply tape, and at the component suction position, the suction nozzle of the component mounting machine is lowered to suck the component in the component supply tape and circuit. It is designed to be mounted on the board. When removing the top tape from the component supply tape, minute dust is generated, so when the operation period of the component mounting machine is extended, this dust not only accumulates in various places in the device and stains the inside of the device, The dust floats in the air and adheres to the suction nozzle and components, causing component suction failure and mounting failure, and dust appears in the component image captured by the camera, causing image processing errors and misrecognition. It can also be a cause.

  Therefore, as described in Patent Document 1 (Japanese Patent Laid-Open No. 2005-277212), the component mounting space of the component mounting machine is configured as a substantially closed space, and outside air is introduced into the component mounting space. In some cases, the pressure generated in the component mounting space is made higher than the atmospheric pressure so that dust generated when the cover tape is peeled outside the component mounting space does not enter the component mounting space.

  Alternatively, as described in Patent Document 2 (Japanese Patent Laid-Open No. 2010-109109), a dust collection nozzle that sucks dust generated when the cover tape is peeled into or near the passage of the component supply tape of each tape feeder. There is something that provided.

  However, in the configuration of Patent Document 1, since the dust generated when the cover tape is peeled is configured not to enter the component mounting space of the component mounting machine, the configuration of the apparatus for realizing this is increased in size as a whole. Therefore, there is a drawback that the component mounting machine is increased in size and cost.

  Moreover, in the structure of patent document 2, since it is the structure which each provides a dust collection nozzle in each tape feeder, it is necessary to modify a tape feeder, and when using the existing tape feeder which is not provided with a dust collection nozzle, No dust effect is obtained.

  Therefore, the problem to be solved by the present invention is to eliminate the problem of dust generated when peeling the cover tape while using the existing component mounter and the existing tape feeder without the need to modify the component mounter or the tape feeder. It is to provide a component supply device that can be solved.

In order to solve the above-mentioned problem, the invention according to claim 1 is equipped with a plurality of tape feeders, the top tape of the component supply tape set on each tape feeder is peeled off, and the components in the component supply tape are mounted as components.

The outlet of the tape discharge duct is located at the top of the plurality of tape feeders. Atsumarichiriana also located below the portion closer to the plurality of the tape feeders including a portion located in the extension straight line of the discharge direction of the component supply tape of the tape feeder of the top surface portion of the tape discharge duct The dust collector is a portion closer to the tape feeder, including a portion located on an extended straight line in the discharge direction of the component supply tape of the plurality of tape feeders, of the upper surface portion of the tape discharge duct. And a dust collecting duct for sucking the air in the tape discharging duct to the outside of the tape discharging duct through the dust collecting hole, and dust generated when the top tape of the component supply tape is peeled off. A fan is provided for sucking into the tape discharge duct along the discharge direction of the component supply tape and sucking into the dust collection duct through the dust collection hole. It is an butterfly. Here, the “upper surface portion of the tape discharge duct” means “a portion where the normal vector of the outer surface forming the tape discharge duct has an upward component” (hereinafter the same). In this configuration, the component feeder is equipped with a dust collector that sucks and collects dust generated when the top tape is peeled off, so there is no need to modify the component mounter or tape feeder, and the existing component mounter While using existing tape feeders, it is possible to solve dust problems (component adsorption failure, mounting failure, image processing error, misrecognition, etc.) that occur when the cover tape is peeled off, and increase the size of component mounting machines and tape feeders. Problems such as cost increase can be solved.

  By the way, if the direction of sucking dust generated when the top tape is peeled off is not along the discharge direction of the component supply tape, the component supply tape discharged from the tape feeder is bent in the direction of the suction force of the dust collector. There is a possibility that the discharge of the component supply tape may be hindered. For this reason, the suction force of the dust collector must be weakened, and the dust collection capability is limited.

Therefore, in the invention according to claim 1, the dust collector is configured to suck and collect the dust generated when the top tape is peeled off along the discharge direction of the component supply tape. In this way, the direction of the suction force of the dust collector acting on the component supply tape is in the direction along the discharge direction of the component supply tape, so even if the suction force of the dust collector is increased, the component supply tape The component supply tape can be discharged smoothly without being disturbed by the suction force of the dust collector. Thereby, both the discharge property of the component supply tape and the increase of the dust collecting ability (suction force) can be achieved.

The present invention, in the component supplying device is provided with a tape discharge duct guides the component supply tape discharged from the tape discharge portion of the upper portion of the plurality of tape feeders to be curved downward from the tape feeder, the tape discharge duct And the outlet of the tape discharge duct is located below the plurality of tape feeders , and the upper surface of the tape discharge duct is located at the top of the plurality of tape feeders. A dust collecting hole is formed in a portion closer to the tape feeder including a portion located on an extended straight line in the discharge direction of the component supply tape of the plurality of tape feeders, and the dust collecting device includes the tape discharge duct. closer to said tape feeder including a portion located in the extension straight line of the discharge direction of the component supply tape of the plurality of tape feeders of the upper surface portion of the And a dust collecting duct for sucking the air in the tape discharging duct to the outside of the tape discharging duct through the dust collecting hole, and dust generated when the top tape of the component supplying tape is peeled off. A fan is provided which is sucked into the tape discharge duct along the discharge direction of the supply tape and sucked into the dust collection duct through the dust collection hole of the tape discharge duct. In this configuration, the inlet of the tape discharge duct is positioned in the discharge direction of the component supply tape of the tape feeder, and the upper surface portion of the tape discharge duct is curved downward, so that the tape feeder of the upper surface portion of the tape discharge duct If dust collecting holes are formed in the part closer to the tape feeder, including the part located on the extended straight line in the discharge direction of the component supply tape, the upper surface of the tape discharge duct in the discharge direction of the component supply tape of the tape feeder The dust collecting hole is located. This makes it possible to efficiently suck the air around the top tape peeling position along the discharge direction of the component supply tape by using the inlet of the tape discharge duct as the suction port of the dust collector. By providing the dust duct, it becomes possible to suck air efficiently, and the dust collecting ability can be enhanced.

Furthermore, as in claim 2, dust collector, it is preferable to a structure having a dust collecting filter which is mounted on the exhaust side of the dust collecting duct. Thus, it is possible to collect efficiently dust in intake air in the dust collecting filter, it is possible to prevent the air containing dust is discharged to the outside.

Hereinafter, an embodiment embodying a mode for carrying out the present invention will be described.
The component supply device 11 is detachably set on the component mounter 12. A caster 13 is provided on the leg portion of the component supply device 11 so that an operator can move by pushing the component supply device 11. A feeder set base 14 is provided on the upper part of the component supply device 11, and a number of tape feeders 15 are detachably mounted on the feeder set base 14.

  Each tape feeder 15 is provided with a tape reel 16 around which a component supply tape is wound. The component supply tape pulled out from the tape reel 16 is pitch-fed to a component suction position, and the top of the upper surface of the component supply tape is placed. The tape (cover tape) is peeled before the component suction position to expose the components in the component supply tape, and the component supply tape is exposed to the inside of the component supply tape by the suction nozzle (not shown) of the component mounting machine 12 at the component suction position. These components are picked up and mounted on the circuit board.

At the top of the rear side of the component supplying device 11 (the discharge direction of the component supply tape), the component supply tape (carrier tape) discharged from the tape discharge portion of the top of each tape feeder 15 on the feeder set table 14 A tape discharge duct 18 that guides the tape feeder 15 so as to curve downward is provided, and the inlet of the tape discharge duct 18 is located in the discharge direction of the component supply tape of the tape feeder 15. The inlet of the tape discharge duct 18 is formed in a horizontally long shape so as to face the tape discharge portion at the top of each tape feeder 15 on the feeder set base 14. The outlet of the tape discharge duct 18 is located below each tape feeder 15 on the feeder set base 14, and a tape cutter 19 is provided at the outlet (lower end opening) of the tape discharge duct 18. Then, the component supply tape is cut, and the cut component supply tape is collected in the tape collection box 21 at the lower part of the component supply device 11.

  At the back side of the component supply device 11, dust generated by peeling the top tape of the component supply tape set on each tape feeder 15 on the feeder set base 14 is sucked along the discharge direction of the component supply tape to collect the dust. A dust collector 22 is provided. Hereinafter, the configuration of the dust collector 22 will be described.

A number of dust collecting holes are formed in a portion closer to the tape discharge portion of the tape feeder 15 including a portion located on an extended straight line in the discharge direction of the component supply tape of the tape feeder 15 in the upper surface portion of the tape discharge duct 18. 23 (see FIG. 3) is formed. Here, the “upper surface portion of the tape discharge duct 18” means “a portion where the normal vector of the outer surface forming the tape discharge duct 18 has an upward component” (hereinafter the same). In order to prevent the component supply tape from being sucked into the dust collection holes 23, the diameter of each dust collection hole 23 is set smaller than the width of the component supply tape. The dust collection duct 24 of the dust collector 22 is formed to be curved downward along the upper surface portion of the tape discharge duct 18, and the opening end portion on the suction side thereof is a tape feeder in the upper surface portion of the tape discharge duct 18. 15 is connected to a portion closer to the tape discharge portion of the tape feeder 15 including a portion located on an extended straight line in the discharge direction of the component supply tape, and all dust collecting holes are formed inside the opening end portion on the suction side. 23 is located.

  The inlet of the tape discharge duct 18 is also used as a suction port of the dust collector 22, and the air sucked into the tape discharge duct 18 from the inlet of the tape discharge duct 18 is a dust collection hole on the upper surface of the tape discharge duct 18. 23 is sucked into the dust collection duct 24 and guided downward along the curved shape of the dust collection duct 24.

  A dust collection filter 26 that collects dust in the air is detachably attached to the exhaust side of the dust collection duct 24 so that the air sucked into the tape discharge duct 18 is filtered by the dust collection filter 26 and discharged. It has become. Below the dust collection filter 26 (exhaust side), one or a plurality of fans 27 for sucking the air in the dust collection duct 24 through the dust collection filter 26 are provided. An exhaust duct 28 is provided on the exhaust side (lower side) of the fan 27 so as to extend downward. Air blown from the fan 27 is guided downward in the exhaust duct 28, and exhaust at the lower end of the exhaust duct 28. It is designed to be discharged from the mouth.

  According to the present embodiment described above, a dust collector that sucks and collects dust generated when the top tape of the component supply tape set on each tape feeder 15 on the feeder set base 14 of the component supply device 11 is peeled off. 22 is provided in the component supply device 11, so that the component mounter 12 and the tape feeder 15 are not required to be modified, and the cover tape is peeled off while using the existing component mounter 12 and the existing tape feeder 15. In addition to solving dust problems (component adsorption failure, mounting failure, image processing error, misrecognition, etc.), problems such as an increase in the size and cost of the component mounting machine 12 and the tape feeder 15 can also be solved.

  By the way, if the direction of sucking dust generated when the top tape is peeled off is not along the discharge direction of the component supply tape, the component supply tape discharged from the tape feeder is bent in the direction of the suction force of the dust collector. There is a possibility that the discharge of the component supply tape may be hindered. For this reason, the suction force of the dust collector must be weakened, and the dust collection capability is limited.

  As a countermeasure, in this embodiment, the dust generated when the top tape of the component supply tape set on each tape feeder 15 on the feeder set base 14 is peeled is sucked along the discharge direction of the component supply tape to collect the dust. Therefore, the suction direction of the dust collector 22 is the direction along the discharge direction of the component supply tape of each tape feeder 15 on the feeder set base 14, and the discharge of the component supply tape is performed in the dust collector 22. The component supply tape can be discharged smoothly without being hindered by the suction force. Thereby, both the discharge property of the component supply tape and the increase of the dust collecting ability (suction force) can be achieved.

  By the way, since the space above each tape feeder 15 on the feeder set base 14 is used as a moving space for the suction nozzle of the component mounting machine 12, a space for providing the suction port of the dust collector 22 above the tape feeder 15. There is not enough room. In particular, in the high-speed mounting machine in which the component suction / mounting speed of the component mounting machine 12 is increased, the suction nozzle lifting / lowering amount is set to the minimum necessary, so that the suction port of the dust collector 22 is located above the tape feeder 15. It is difficult to provide the space.

Considering this point, in this embodiment, paying attention to the tape discharge duct 18 provided in the discharge direction of the component supply tape of each tape feeder 15 on the feeder set base 14, this tape discharge duct 18. Since the dust collection hole 23 is formed in the portion closer to the tape feeder 15 including the portion located on the extended straight line in the discharge direction of the component supply tape of the tape feeder 15 in the upper surface portion of the feeder , the feeder set base 14, the dust collecting holes 23 on the upper surface of the tape discharge duct 18 are positioned in the discharge direction of the component supply tape of each tape feeder 15. Accordingly, the air around the top tape peeling position can be efficiently sucked in the discharge direction of the component supply tape by using the inlet of the tape discharge duct 18 as the suction port of the dust collector 22, and the dust collection capability is improved. Can be increased.

As a reference example related to the present invention, when there is a space on the lower surface side of the tape discharge duct 18, a large number of dust collection holes having a hole diameter smaller than the width of the component supply tape are formed on the lower surface portion of the tape discharge duct 18. It is conceivable that a hole is formed and a dust collection duct, a dust collection filter, a fan, and an exhaust duct are provided on the lower surface side of the tape discharge duct 18.

In addition, the present invention is not limited to the above embodiments, it is needless to say that can be variously modified without departing from the Abstract.
