[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an electronic component supply device according to an embodiment of the present invention will be described with reference to the accompanying drawings. This electronic component supply device supplies an electronic component such as a chip capacitor and a chip resistor to a device main body of an electronic component mounting device. These electronic components are mounted on a carrier tape, and the intermittent feed of the carrier tape is performed. These are supplied one by one to the apparatus main body.
[0009]
1 and 2 are overall side views of the electronic component supply device. The electronic component supply device 1 includes an apparatus frame 2 and a carrier tape reel 8 rotatably mounted on a support 3 fixed to the apparatus frame 2. A tape feed mechanism 4 for intermittently feeding the carrier tape C unwound from the carrier tape reel 8 to the component pick-up position S of the electronic component B, peeling off the cover tape Ca of the carrier tape C before the component pick-up position S, and A cover tape winding mechanism 5 for winding, a shutter mechanism 6 for opening the upper side of the electronic component B sent to the component unloading position S to enable pickup of the electronic component B, a tape feeding mechanism 4, and a cover tape winding mechanism A drive cylinder 7 serving as a drive source of the mechanism 5 and the shutter mechanism 6 is provided.
[0010]
The carrier tape C on which the electronic components B are mounted at predetermined intervals is provided in a state wound around the carrier tape reel 8. The carrier tape reel 8 is braked and rotated, and the carrier tape C fed from the carrier tape reel 8 is moved under the suppressor 9 disposed in the tape path before the component take-out position S, so that the component take-out position is reduced. It is sent to S. As shown in FIG. 3, an opening 91B is formed around the component take-out position S of the suppressor 9, and above the take-out position S, the component accommodating portion where the cover tape Ca of the carrier tape C is peeled off is opened and closed. A shutter body 61B of the shutter mechanism 6 is provided. The shutter body 61B has a thin plate shape and is fixed to the lower surface of the shutter base 61A. The shutter base 61A is movable while a pin 96 projecting from the suppressor 9 is guided along the elongated hole 65.
[0011]
The suppressor 9 accommodates the electronic component in the accommodating portion and prevents the electronic component from dropping from the carrier tape that is intermittently fed toward the component extracting position.
[0012]
As shown in FIG. 4, the cover tape Ca of the carrier tape C in the embossed tape (the cover tape is thicker than the paper tape) is peeled around the outer end of the shutter body 61B as a fulcrum, and the outer end of the shutter body 61B is removed. The cover tape Ca that has been peeled off between the cover tape Ca and the end surface forming the opening 91B around the component take-out position S of the suppressor 9 passes through and is taken up by the cover tape reel 51 of the cover tape take-up mechanism 5.
[0013]
Further, a slit 10 is formed in the shutter base 61A before the fulcrum of peeling of the cover tape Ca of the carrier tape C in the embossed tape, and the cover tape Ca of the carrier tape C in the paper tape passing through the slit 10 is formed by the slit. The cover tape reel 10 of the cover tape winding mechanism 5 is similarly peeled off through the opening 91A of the suppressor 9 through the opening end of the opening 10 as a fulcrum.
[0014]
The gap between the outer end of the shutter body 61B and the end surface of the suppressor 9 forming the opening 91B around the component take-out position S is formed wider than the opening width of the slit 10 (the width in the transport direction of the electronic components).
[0015]
That is, when the cover tape Ca is an embossed tape (see FIG. 6) thicker than the paper tape (see FIG. 7), a connection tape Cc of a fixed length is attached to the carrier tape C and the cover tape Ca for splicing. As described above, the cover tape Ca peeled between the outer end portion of the shutter body 61B and the end surface forming the opening 91B around the component take-out position S of the suppressor 9 is made to pass therethrough. The cover tape Ca to which the connection tape Cc is adhered can be passed.
[0016]
When the cover tape Ca is a paper tape (see FIG. 7) thinner than the embossed tape (see FIG. 6), a connection tape Cc of a fixed length is attached to the carrier tape C and the cover tape Ca for splicing. Also, as described above, since the cover tape Ca is made to pass through the slit 10 of the shutter base 61A, even the slit 10 formed as narrow as possible can pass the cover tape Ca to which the connection tape Cc is attached. it can.
[0017]
Then, the electronic component B mounted on the carrier tape C faces the component extraction position S with the cover tape Ca peeled off. When the electronic component B reaches the component pick-up position S, the shutter mechanism 6 opens, the mounting head (not shown) on the apparatus main body side descends, and the suction nozzle of the electronic component B sucks and picks up the electronic component B to print the printed circuit board ( (Not shown).
[0018]
The drive cylinder 7 is swingably supported by the apparatus frame 2 at the tail end of the cylinder body 21. The tape feed mechanism 4, the cover tape winding mechanism 5, and the shutter A transmission plate 23 for transmitting power to the mechanism 6 is fixed. The transmission plate 23 advances and retreats due to the advance and retreat of the piston rod 22, and the carrier tape C is fed by the tape feed mechanism 4 by the retracting operation (pulling operation), the cover tape is wound by the cover tape winding mechanism 5, and the shutter is released. The closing operation of the mechanism 6 is performed, and the opening operation of the shutter mechanism 6 is performed by the forward operation.
[0019]
The tape feed mechanism 4 meshes with a sprocket 31 that meshes with and feeds a feed hole formed in the carrier tape C, a ratchet wheel 32 fixed so as to overlap the sprocket 31 and disposed coaxially, It has a feed claw 33 for intermittently rotating the ratchet wheel 32, and a feed lever 34 that rotatably supports the feed pawl 33 and is provided coaxially and swingably with the ratchet wheel 32. The transmission plate 23 is rotatably connected to an end of the feed lever 34 via a support shaft 25, and the feed lever 34 swings with the movement of the transfer plate 23 due to the extension of the piston rod 22. Then, the feed pawl 33 exceeds the teeth of the ratchet wheel 32, and conversely, the feed lever 34 swings with the movement of the transmission plate 23 due to the contraction of the piston rod 22, and the feed pawl 33 rotates the ratchet wheel 32 intermittently. When the ratchet wheel 32 intermittently rotates, the sprocket 31 intermittently rotates at the same time, and intermittently feeds the carrier tape C.
[0020]
The cover tape winding mechanism 5 includes a cover tape reel 51 rotatably attached to the apparatus frame 2 via a support shaft 52, a one-way clutch 53 incorporated between the cover tape reel 51 and the support shaft 52, The swing lever 54 intermittently rotates the cover tape reel 51 in one direction via the clutch 53, and a connecting arm 55 connecting the swing lever 54 and the transmission plate 23. The connecting arm 55 has one end connected to the transmission plate 23 via the connecting pin 24, extends rearward in parallel with the drive cylinder 7, and is rotatably attached to the swing lever 54 via the pin. .
[0021]
The swing lever 54 is formed integrally with a ring portion fixed to the inner side of the one-way clutch 53 and an arm portion extending radially from the ring portion, and a connecting arm 55 is rotatably connected to the arm portion. Pin-connected. When the swing lever 54 swings via the connecting arm 55 as the transmission plate 23 advances and retreats, the cover tape reel 51 moves in one direction (the winding direction) due to the interaction between the unillustrated feed stopper and the one-way clutch 53. Rotate intermittently. As a result, the cover tape Ca peeled off from the carrier tape C is wound around the cover tape reel 51 without causing slack.
[0022]
The shutter base 61A of the shutter mechanism 6 is formed with a guide elongated hole 62 into which a pin 92 protruding from a side portion of the suppressor 9 is fitted so that the shutter 92 can reciprocate on the suppressor 9. When the piston rod 22 is extended, the feed lever 34 swings via the transmission plate 23, and the pin 35 projecting from the feed lever 34 is fitted to open the shutter base 61A and the shutter body 61A. A groove 63 is formed.
[0023]
Therefore, as described above, the shutter base 61A can move while the pin 96 protruding from the suppressor 9 is guided along the long hole 65, and the guide long hole is provided on a pair of pins 92 provided on the side surface of the suppressor 9. By engaging the pin 62, the pin 92 advances and retreats (opens and closes) using the pin 92 as a guide. Open and close. That is, the shutter body 61B presses the electronic component B sent to the component removal position S so as not to jump out of the accommodating portion of the carrier tape C in the state where the shutter body 61B is moved to the closing position, and moves to the opening position. It retracts from the upper side of the electronic component B so that it can be picked up.
[0024]
On the other hand, as shown in FIG. 8, an adjusting mechanism 57 for adjusting the open end position of the shutter body 61B is provided. That is, the stroke is adjusted by moving and fixing the fixing plate 59 on which the mounting plate 58 to which the driving cylinder 7 is mounted is fixed to the apparatus frame 2 at an appropriate pitch. Specifically, the fixing plate 59 is fixed to the device frame 2 by screws 55A and 55B through the horizontally long holes 59A and the vertically long holes 59B formed in the fixing plate 59, and the position of the horizontally long holes 59A is adjusted appropriately. By fixing screws 55A and 55B to arbitrary mounting holes 2A among a plurality (four) of mounting holes 2A opened at equal intervals in device frame 2, the open end position of shutter body 61B is adjusted. .
[0025]
Here, first, the feeding operation of the carrier tape C of the embossed tape, the winding operation of the cover tape Ca, and the opening and closing operation of the shutter mechanism 6 shown in FIG. 6 will be described. First, when the drive cylinder 7 is driven, the feed lever 34 swings with the movement of the transmission plate 23 due to the extension of the piston rod 22, the feed pawl 33 exceeds the teeth of the ratchet wheel 32, and the carrier tape C is intermittently fed. Prepare. Further, when the feed lever 34 swings via the transmission plate 23 when the piston rod 22 is extended by the driving of the drive cylinder 7, the pin 35 projecting from the feed lever 34 is fitted into the fitting groove 63. Therefore, the shutter base 61A and the shutter body 61B are moved rearward, and the interval between the outer end of the shutter body 61B and the end face forming the opening 91B around the component take-out position S of the suppressor 9 is widened and opened. Accordingly, the mounting head (not shown) of the apparatus main body descends, and its suction nozzle (not shown) sucks and picks up the most advanced electronic component B at the component picking position S through the opening 91B of the suppressor 9. And mount it on the printed circuit board of the device body.
[0026]
Conversely, the feed lever 34 swings with the movement of the transmission plate 23 due to the contraction of the piston rod 22, and the feed pawl 33 intermittently rotates the ratchet wheel 32. At the same time, the sprocket 31 intermittently rotates, and the carrier tape C And the shutter body 61B is moved forward to form an outer end of the shutter body 61B and an opening 91B around the component removal position S of the suppressor 9. And close it.
[0027]
Further, when the drive cylinder 7 is driven, the swing lever 54 swings via the connecting arm 55 with the movement of the transmission plate 23 due to the extension of the piston rod 22, but a feed stopper (not shown) and a one-way Although the cover tape reel 51 does not rotate due to the interaction with the clutch 53, the feed lever 34 swings with the movement of the transmission plate 23 due to the contraction of the piston rod 22, and the feed pawl 33 rotates the ratchet wheel 32 intermittently to generate a sprocket. When the carrier tape C is intermittently fed by the 31 intermittent rotation, that is, when the shutter body 61B is closed as described above, the cover tape reel 51 intermittently rotates in one direction (winding direction). As a result, the cover tape Ca is wound around the cover tape reel 51 without being loosened while being peeled off from the carrier tape C.
[0028]
As described above, when the cover tape Ca is an embossed tape (see FIG. 6) thicker than the paper tape (see FIG. 7), the connection tape Cc of a fixed length is attached to the carrier tape C and the cover tape Ca for splicing. As described above, the cover tape Ca peeled between the outer end portion of the shutter body 61B and the end surface forming the opening 91B around the component take-out position S of the suppressor 9 is allowed to pass even as described above. Thus, the cover tape Ca to which the connection tape Cc is stuck can be reliably passed.
[0029]
Next, the feeding operation of the paper tape carrier tape C, the winding operation of the cover tape Ca, and the opening / closing operation of the shutter mechanism 6 shown in FIG. 7 will be described. First, when the drive cylinder 7 is driven, the feed lever 34 swings with the movement of the transmission plate 23 due to the extension of the piston rod 22, the feed pawl 33 exceeds the teeth of the ratchet wheel 32, and the carrier tape C is intermittently fed. When the feed lever 34 swings through the transmission plate 23, the shutter base 61A and the shutter body 61B are moved rearward, and the outer end of the shutter body 61B and the opening around the component removal position S of the suppressor 9 are opened. The suction nozzle opens and widens the gap with the end face forming 91B, and the suction nozzle sucks out the leading-edge electronic component B at the component pick-up position S through the opening 91B and mounts it on the printed circuit board.
[0030]
Then, as described above, conversely, the feed lever 34 swings with the movement of the transmission plate 23 due to the contraction of the piston rod 22, and the feed pawl 33 intermittently rotates the ratchet wheel 32, so that the sprocket 31 simultaneously rotates intermittently. Then, the carrier tape C is intermittently fed to supply the electronic component B to the component take-out position S, and the shutter body 61B is moved forward to open the outer end of the shutter body 61B and the suppressor 9 around the component take-out position S. Close the gap with the end face forming 91B.
[0031]
Further, when the drive cylinder 7 is driven, the swing lever 54 swings via the connecting arm 55 with the movement of the transmission plate 23 due to the extension of the piston rod 22, but the feed stopper and the one-way clutch 53 The cover tape reel 51 does not rotate due to the interaction between the sprocket 31 and the feed lever 34 swings with the movement of the transmission plate 23 due to the contraction of the piston rod 22, and the feed pawl 33 rotates the ratchet wheel 32 intermittently and the sprocket 31 intermittently moves. When the carrier tape C is intermittently fed by rotation, that is, when the shutter body 61B is closed as described above, the cover tape reel 51 intermittently rotates in one direction (the winding direction). As a result, the cover tape Ca is wound around the cover tape reel 51 without being loosened through the slit 10 of the shutter body 61B and the opening 91A of the suppressor 9 while being peeled off from the carrier tape C.
[0032]
As described above, when the cover tape Ca is a paper tape (see FIG. 7) thinner than the embossed tape (see FIG. 6), the connection tape Cc of a fixed length is attached to the carrier tape C and the cover tape Ca for splicing. As described above, since the cover tape Ca is made to pass through the slit 10 of the shutter base 61A and the opening 91A of the suppressor 9 as described above, the connection tape Cc can be pasted even on the slit 10 formed as narrow as possible. Cover tape Ca that has passed through.
[0033]
When the present invention is applied to a carrier tape having a small feed pitch, for example, a width of 8 mm or less, the effect becomes remarkable.
[0034]
