Description

  The present invention relates to a tape-type component supply device that supplies chip-shaped electronic components to a component mounting device.

2. Description of the Related Art Conventionally, in a board unit production line, a chip-shaped electronic component (hereinafter simply referred to as a component) is held between two types of tape members that are mounted on a component mounting apparatus and have side end portions bonded together. There is a tape-type component supply device which is also called a tape feeder or simply a feeder. (For example, refer to Patent Document 1.)
FIG. 3 (a) is an external perspective view of a component mounting device used with such a tape-type component supply device mounted, and FIG. 3 (b) is arranged on the component supply stage of the component mounting device. It is a perspective view which shows the example of the tape components supply apparatus of the state performed.

  The component mounting apparatus 1 shown in FIG. 1 (a) includes a display input device 2 composed of a liquid crystal display and a touch panel, a monitor device 3 composed of a CRT display, and an alarm lamp 4 for informing the operating state, on the ceiling cover. The lower base 5 is provided with a pair of fixed and movable parallel substrate guide rails 6 at the center of the surface, and above them, it is not visible behind the protective cover 7 in the figure, It has a component mounting head that can move left and right and up and down.

  The component mounting head is detachably equipped with a suction nozzle for picking up a component or a gripping chuck for gripping, picks up a desired component from various connected component supply devices, and loads the picked-up component by the board guide rail 6. And mounted on a substrate that is fixed in position inside. The component mounting apparatus 1 is provided with component supply stages 8 before and after the component mounting device 1.

As shown in FIG. 2B, the component supply stage 8 is provided with a large number of mounting and fixing holes 9 at the front and rear, and the tape component supply device 10 is connected and arranged by these mounting and fixing holes 9.
Depending on the size of the component mounting device 1 and the size of components to be supplied, 50 to 70 tape component supply devices 10 are usually attached to the component supply stage 8. That is, when the front and rear component supply stages 8 are combined, 100 to 140 tape component supply devices 10 are arranged in one component mounting device 1.

  A component tape containing a component is wound around the component reel 11 of the tape component supply apparatus 10, and this component tape is pulled out to the component supply port 12, and is placed on the top tape 13-1 and the storage tape 13-2. The parts separated and accommodated in the accommodation tape 13-2 are exposed to the component supply port 12. The component mounting head of the component mounting apparatus 1 takes out the exposed component by a suction nozzle or a gripping chuck and mounts it on the substrate. Thereafter, the separated top tape 13-1 is taken up by the take-up reel 14, and the receiving tape 13-2 falls and accumulates in an empty space inside the main body device by its own weight.

As described above, the storage tape 13-2 drops and accumulates in the empty space inside the main body device because the recovery operation is troublesome, so that the storage tape 13-2 falls and accumulates in the work path of the production line outside the main body device. What has been proposed is proposed. (For example, see Patent Document 2.)
FIG. 4 is a side view of such a tape-type component supply device. The tape-type component supply device 15 is mounted while being slid horizontally on the component supply stage of the component mounting device, and is configured so that the upper and lower work spaces at the time of mounting can be reduced.

  5 (a) and 5 (b) are diagrams showing a state where the tape-type component supply device 15 is attached to and detached from the component supply stage. Referring to FIG. 4, the attachment / detachment state of the tape-type component supply device 15 to the component supply stage will be described. First, the worker is provided at the upper part of the rear end (left end in the drawing) of the tape-type component supply device 15. The operating rod 16 is rotated counterclockwise as indicated by the arrow B in FIG. 5 (a) with the support pin 17 as a fulcrum, so that the control rod 16 is raised in the up-rear direction (upper left direction in the figure). As a result, the fixed hook 18 with a roller interlocked therewith is turned upward in the forward direction (right upward in FIG. 5A), that is, in the counterclockwise direction in FIG. 5A.

5A and 5B, the component supply stage 8 ′ of the component mounting device 1 ′ has a slide rail engaging portion of the tape-type component supply device 15 for each mounting position of the tape-type component supply device 15. An engagement groove 21 corresponding to 19 is formed.
Since the fixed hook 18 with a roller that has been lifted by rotating forward and upward as described above opens the entry path of the slide rail engaging portion 19 to the engaging groove 21, the worker can handle the handle 20. Thus, while holding the tape-type component supply device 15, the front end of the slide rail engaging portion 19 can be easily inserted into the front end portion (left end portion in the figure) of the engaging groove 21. Then, as shown in FIG. 5B, the worker engages in the tape type until the final position as shown in FIG. 5B while inserting the slide rail engaging portion 19 into the engaging groove 21 as shown in FIG. The component supply device 15 is pushed in.

  Then, as shown by an arrow C in FIG. 5 (b), when the worker rotates the operating rod 16 in the clockwise direction and tilts it down in the direction in contact with the main body of the tape-type component supply device 15, interlocked with this. Then, the fixing hook 18 with the roller is rotated in the clockwise direction as indicated by an arrow D, and the tip of the bowl with the roller of the fixing hook 18 with the roller grips the end of the component supply stage 8 '. Thus, the tape-type component supply device 15 is fixed to the component supply stage 8 '. When removing, the operation is the reverse of the above.

  As shown in FIG. 4, the tape-type component supply device 15 draws out a component tape (not shown) from a component reel 23 held by a component reel holding unit 22 and passes through a conveyance path 24 inside the device main body to be transferred to the tape. Is pulled out to the component supply port 26 under the tape pressing member 25 which serves both as a guide and as a lift prevention. The upper and lower tapes of the component tape pulled out to the component supply port 26 are peeled off to expose the components from the storage portion, and the exposed components are sucked by a suction nozzle at the tip of the component mounting head (not shown) of the component mounting apparatus 1 ′. To be taken out.

The upper tape that has been peeled up and down is collected in a tape collecting container 27, and the lower receiving tape 28 (see FIG. 5B) passes through a discharge path 29 in the main body of the tape-type component supply device 15, As shown by the arrow E in FIG. 4, it falls down to the outside and accumulates in the work path of the production line as shown in FIG.
JP 2002-246789 (paragraphs [0003] to [0005], FIG. 3) JP 2003-078284 (paragraph [0002], first four lines of paragraph [0005], FIG. 3)

  By the way, the above-described conventional tape-type component supply device 10 or 15 falls and accumulates inside the component mounting device like the peeled lower receiving tape 13-2, or like the receiving tape 28. There is no difference in the fact that the storage tape that has fallen by its own weight is directly connected to the main body of the tape-type component supply device, with the only difference that it falls and accumulates in the work path of the production line.

  When a worker removes or replaces a tape-type component supply device from the component supply stage, if the storage tape remains connected to the tape-type component supply device, the storage tape becomes entangled with the adjacent tape-type component supply device. Since the handling is troublesome, before removing the tape-type component supply device from the component supply stage, the tape-type component supply device is separated from the tape-type component supply device of the storage tape with a scissors. Is removed from the component supply stage.

Therefore, it is necessary for the worker to always wear a bag or to prepare a bag in a storage place determined for each component mounting device.
However, in this case, in addition to troublesome storage and management of the bag, the storage tape is separated by the bag in a narrow work space near the component supply stage where a large number of tape-type component supply devices are arranged. The work is extremely troublesome and unexpectedly time-consuming, and has the problem of hindering the improvement of the overall work efficiency.

  An object of the present invention is to provide a tape-type component supply device that automatically cuts a discharged storage tape when the tape-type component supply device is removed from or replaced with a component supply stage in view of the above-described conventional situation. That is.

The configuration of the tape-type component supply device according to the present invention will be described below.
The tape-type component supply device of the present invention seals and stores a chip-shaped electronic component in a component tape composed of a storage tape and a top tape adhered on the storage tape, and attaches / detaches the operating rod. After being mounted on the mounting unit, the component tape is intermittently transported from the component tape holding unit to the supply port, and the receiving tape and the top tape Is a tape-type component supply device that exposes the chip-shaped electronic component on the receiving tape and sequentially supplies the chip-shaped electronic component to the component mounting head of the component mounting device, and is formed inside the device main body. A discharge path for guiding the accommodation tape after the chip-shaped electronic component is supplied to the component mounting apparatus to be discharged out of the apparatus main body, and the accommodation tape provided in the discharge path is cut. Configured to include a mechanism, a.

  The scissor mechanism is configured to cause the scissors to be cut in the discharge path in conjunction with, for example, the removal operation of the operation scissors. Moreover, the said discharge path is formed, for example so that the said accommodation tape may be discharged to the apparatus main body back.

  According to the present invention, when the worker removes or replaces the tape-type component supply device from the component supply stage, the hook-type mechanism interlocks with the removal operation by the operation rod performed by the worker, from the tape-type component supply device. The work tape can be cut off from the tape-type component supply device before the worker removes the tape-type component supply device from the component supply stage. When a worker removes the tape-type component supply device from the component supply stage, it is possible to prevent the storage tape from becoming entangled with the adjacent tape-type component supply device, and the worker always wears a bag. Or, there is no hassle of having a bag in the storage place specified for each component mounting device, and many tape-type component supply devices are arranged. This eliminates the cumbersome and time-consuming task of separating the storage tape with a scissors in a narrow work space near the component supply stage, so that workers can remove the tape-type component supply device from the component supply stage. When or when replacing, the work efficiency of the entire board unit production line is improved.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a side view of a tape-type component supply device according to an embodiment. The configuration of the tape-type component supply device 30 shown in the figure is the same as the configuration of the tape-type component supply device 15 shown in FIG. 4 except for the configuration of the main part related to the present invention. Only parts necessary for explanation are given the same numbers as in FIG. 4, and new constituent parts related to the present invention are given new numbers.

  As shown in FIG. 1, in the tape-type component supply device 30 of this example, the discharge path 29 for discharging the storage tape 28 discharges the storage tape 28 to the rear of the tape-type component supply device 30 main body (left side in FIG. 2). It is formed properly. Further, in the vicinity of the discharge port of the discharge path 29, there is provided a scissor mechanism storage portion 31 that stores the scissors drive portion and scissors of the scissors mechanism of the present invention.

  In the example shown in FIG. 2A, the sliding pin 35 is attached to the interlocking portion 32 side, and the pin engaging long hole (or long groove) 36 is formed on the frame 30-1 side. Conversely, when the sliding pin 35 is attached to the frame 30-1 side, the position of the sliding pin 35 is the same as that in FIG. 2 of the pin engagement long hole (or long groove) 36 formed on the interlocking portion 32 side. Are arranged at the opposite position, that is, at the left end.

  The interlocking portion 32 is integrally formed with a heel drive portion 37 for driving the heel at an approximately central portion thereof. The scissors driving portion 37 is for driving the scissors mechanism, and the left-side oblique side of the isosceles triangle formed by further punching the central convex portion of the thin plate constituting the interlocking portion 32 has an arc shape. A pin drive cam 38 is formed.

  A cam engaging pin 39 is slidably contacted with the pin drive cam 38, and the operating rod 16 is tilted as shown in FIG. b) The cam engaging pin 39 is in contact with the uppermost part of the pin drive cam 38 in the state fixed to the reference). In this state, the cam engagement pin 39 is in contact with the right end portion of the pin engagement long hole 41 formed on the frame 30-1 side on the other side.

  FIG. 2B is an enlarged view showing the heel mechanism storage portion 31 in the above state. As shown in FIG. 2B, most of the interior of the saddle mechanism storage portion 31 is occupied by an air joint 43, and a cam inserted into the pin engagement long hole 41 in the air joint 43. The tip of the engaging pin 39 is fixed.

  The air joint 43 is a relay mechanism that transmits air pressure of squeezing and degassing controlled from the component supply stage 42 side to the conduction pipe 45 via the connection pipe 44, and a tape-type component supply device to the component supply stage 42. At the time of fixing 30, the connection pipe 44 of the air joint 43 is fitted and connected to a compressed air pipe connection hole (not shown) on the component supply stage 42 side, as shown in FIG.

  A saddle guide groove 46 is formed below the air joint 43. A cutting blade 47 is slidably disposed in the saddle guide groove 46, and the upper portion of the rear end (right end in the figure) of the cutting blade 47 is located above. The air joint 43 is fixed to the lower part of the rear end (left end in the figure). A cutting edge 47-1 is formed at the front end portion (left end in the figure) of the cutting blade 47.

  Corresponding to the cutting edge 47-1, the terminal end (lower end in the figure) of the discharge path 29 of the accommodation tape 28 shown in FIG. 1 coincides with the extended line of the upper surface of the flange guide groove 46 with which the cutting edge 47-1 is in sliding contact. The shear surface 29-1 with respect to the blade edge 47-1 is formed by being cut out at the surface, and a flange portion is formed by the blade edge 47-1 and the shear surface 29-1.

  FIGS. 3A and 3B are diagrams for explaining the operating state of the hook mechanism of the tape-type component supply device 30 having the above-described configuration. When a worker removes the tape-type component supply device 30 from the component supply stage 42 for removal or replacement, first, the operation rod 16 is used as a fulcrum as shown in FIG. Then, as shown by the arrow F in FIG. 2, it is rotated in the counterclockwise direction to cause upward and rearward (upper left direction in the figure).

  Then, in conjunction with the raising of the operating rod 16, one end shown on the left side of the interlocking portion 32 is pulled by the support pin 34 in an obliquely upper left direction as indicated by an arrow G in the figure. As a result, the other end shown to the right of the interlocking portion 32 shown in FIG. 2 (a) is moved to the left while sliding the slide pin 35 to the left in the pin engagement long hole (or long groove) 36. The fixed hook 18 is moved to rotate counterclockwise, and the engagement with the component supply stage 42 is released.

  At the same time, as described above, the left end of the interlocking portion 32 is attracted in the diagonally upper left direction, so that the eyelid drive portion 37 at the substantially central portion of the interlocking portion 32 is also attracted in the obliquely upper left direction, The pin drive cam 38 moves obliquely from the position shown in FIG. 2 (a) to the upper left as shown in FIG. 3 (a).

As a result, the cam engaging pin 39 that is inscribed in the pin drive cam 38 comes into contact with the left end of the pin engagement long hole 41 and stops along the pin engagement long hole 41 while slidingly contacting the pin drive cam 38. Move to the left until
As the cam engagement pin 39 moves to the left, as shown in FIG. 3 (b), the air joint 43 moves to the left in the saddle mechanism housing portion 31, and the connecting pipe 44 is moved to the component supply stage 42 side. Is released from the engagement with the compressed air pipe connection hole (not shown), and the cutting blade 47 is pushed leftward along the guide groove 46.

  As a result, the cutting edge 47 presses the cutting edge 47-1 against the surface of the unnecessary storage tape 28 (see FIG. 1, not shown in FIG. 3 (b)) that hangs down from the inside of the discharge passage 29 to the outside. The cutting edge 47-1 is pushed out so as to be in sliding contact with the lower surface of the shearing surface 29-1 at the end of the discharge passage 29, and the accommodation tape 28 is sheared and cut up and down.

  In this way, the hook mechanism of the hook mechanism storage unit 31 is not required to hang down from the discharge path 29 to the outside downward in conjunction with the removal operation of the tape-type component supply device 30 from the component supply stage 42 by the operation rod 16. Since the storage tape 28 is cut in the discharge path 29, when the worker removes the tape-type component supply device 30 from the component supply stage 42, the portion of the storage tape 28 that protrudes from the discharge port 29 to the outside is It is automatically cut and separated from the tape-type component supply device 30.
