By this, the

pulleys

16 and 28 are provided with a tension region S in which the range between the pulleys 16 and 28 (that is, the range from the upstream side of the joining position J to the downstream side of the joining position T) In the state, the carrier tape P and the cover tape Q are intermittently sent. The tension area S of the carrier tape P is in a state where a tension of a certain magnitude is given in the tape transport direction D when the carrier tape P is stopped.

In the present embodiment, in a state where the tension region S is provided on the carrier tape P, the transport mechanism 11 for feeding the carrier tape P is mainly configured by the pulley 16, the servomotor 19, the pulley 28 and the servomotor 34. The upper guide 12 is disposed above the tension area S of the carrier tape P.
At the timing when the carrier tape P is stopped, the suction nozzle 20 releases the suction of the electronic component W and drops the electronic component W into the pocket P1, and the pressing member 23 contacts the cover tape Q to cover the cover tape Q. It is adhered to the carrier tape P.

Further, as shown in FIG. 1 and FIG. 3, a push-up mechanism 13 is attached to the base unit 15 to press the upstream side of the joining position J of the tension region S of the carrier tape P against the upper guide 12 from below. The push-up mechanism 13 is an example of an elastic member (an example of a contact portion 35 in contact with the tension region S of the carrier tape P from below on the upstream side of the joining position J) and an urging portion applying an upward force to the contact portion 35 In the embodiment, the spring members 36 and 37) are provided.

In the contact portion 35, as shown in FIG. 7, the portion located immediately below the flat portions P2 and P3 of the carrier tape P protrudes upward as compared to the region in which the pocket P1 of the carrier tape P is formed. The flat portions P2 and P3 of the carrier tape P (that is, regions on both sides in the width direction of the carrier tape P with reference to the pocket P1) are contacted without contacting the pocket P1. In the present embodiment, in the fixed block 33 as well as the contact portion 35, the portion of the carrier tape P located immediately below the flat portions P2 and P3 is upward compared to the area where the pocket P1 of the carrier tape P is formed. It protrudes and contacts flat portions P2 and P3 of the carrier tape P without contacting the pocket P1.

As shown in FIG. 3, the contact portion 35 is long in the tape transport direction D and disposed horizontally, and one end in the longitudinal direction is located immediately below the upstream end of the upper guide 12 and the other end is located at the joining position J doing. Therefore, the push-up mechanism 13 presses the entire range from the position directly under the upstream end of the upper guide 12 of the tension area S of the carrier tape P to the joining position J against the upper guide 12.

Since the tension area S of the carrier tape P is always in contact with the upper guide 12 by the contact portion 35, the carrier tape P and the carrier tape P produced by the heating portion 32 of the pressing member 23 being intermittently pressed against the cover tape Q Vibration of the cover tape Q can be suppressed. In addition, when the carrier tape P and the cover tape Q are stopped, the vibration generated in the carrier tape P and the cover tape Q is suppressed also by the tension area S of the carrier tape P being pulled by a predetermined force. There is.

Then, on the upstream end side of the upper guide 12, as shown in FIGS. 4 (A) and 4 (B), a tapered portion 12a whose lower surface gradually rises toward the upstream is formed. The tapered portion 12a is formed on the upper guide 12 in order to: 1) prevent the carrier tape P pressed against the upper guide 12 from being caught on the upper guide 12 and 2) suction nozzle This is because the electronic component W that has been released from suction by the step 20 and dropped into the pocket P1 is guided by the tapered portion 12a and stably accommodated in the pocket P1.
In the present embodiment, as shown in FIG. 4A, the upper guide 12 covers the pocket P1 located one downstream side of the pocket P1 disposed at the insertion position I from above.

Note that instead of the contact portion 35, as shown in FIG. 8, a contact portion 35a that contacts the flat portion P2, P3 of the carrier tape P in a non-contact manner and contacts the pocket P1 of the carrier tape P from below is adopted. It is possible to employ a contact portion that contacts the pocket P1 and the flat portions P2 and P3 of the carrier tape P from below.

The vibration generated in the carrier tape P and the cover tape Q causes the electronic component W to pop out from the pocket P1 on the upstream side of the pasting position T or cause the electronic component W to be turned upside down in the pocket P1. . Therefore, by suppressing the occurrence of vibrations in the carrier tape P and the cover tape Q, the electronic component W can be stably enclosed in the pocket P1 in a predetermined arrangement.

As shown in FIGS. 1, 3 and 9, a position detection sensor (an example of position detection means) 38 for detecting the height position of the contact portion 35 is attached to the base unit 15. As shown in FIG. 9, the position detection sensor 38 is connected to a control unit 40 to which warning generation means 39 for emitting a warning sound and a warning display,

servomotors

19 and 34, and a pressing member 23 are connected. . The position detection sensor 38 may be contact or non-contact.

Here, in a state where a part of the electronic component W protrudes upward from the pocket P1 of the carrier tape P to which the cover tape Q is not adhered, or in a state where the entire electronic component W is disposed outside the pocket P1, the electronic component W contacts the upper guide 12 to lower the contact portion 35. Therefore, the predetermined drop of the contact portion 35 means that there is an abnormality in the arrangement of the electronic component W, and that the electronic component W can not be properly sealed in the pocket P1.

Therefore, when the position detection sensor 38 detects that the contact portion 35 is lowered below a predetermined lower limit position, the control unit 40 detects the occurrence of an abnormality, and generates a warning generation unit 39, a servomotor 19, A signal indicating the occurrence of an abnormality is sent to 34 and the pressing member 23.
When a signal indicating the occurrence of an abnormality is transmitted from the control unit 40, the warning generation means 39 sounds a warning sound and displays a warning to make the operator recognize that a problem has occurred, and the

servomotors

19 and 34 output With the axis stopped, the transport of the carrier tape P is stopped, and the pressing member 23 stops in a non-contact arrangement with the cover tape Q. Instead of the warning generation means 39, warning generation means for emitting only one of the warning sound and the warning display may be adopted.

Further, in the present embodiment, as shown in FIGS. 1 and 3, the lower guide 41 in contact with the carrier tape P to which the cover tape Q is adhered is fixed to the base unit 15 on the downstream side of the application position T It is done. The lower guide 41 is long in the tape transport direction D, and is disposed below the upper guide 12. The cover tape Q and the carrier tape P pass between the upper guide 12 and the lower guide 41 while being in contact with the upper guide 12 and the lower guide 41, respectively.

In the lower guide 41, as shown in FIG. 7, the portion of the carrier tape P located immediately below the flat portions P2 and P3 is the same as the contact portion 35 in the area where the pocket P1 of the carrier tape P is formed. In comparison with the above, since it projects upward, the flat portions P2 and P3 of the carrier tape P are contacted from below without contacting the pocket P1.
The contact portion 35 and the lower guide 41 are flat in order to prevent the carrier tape P from being wrinkled or the like in the portion in contact with the carrier tape P. And as for the contact part 35 and the lower side guide 41, the part which contacts carrier tape P is formed with a metal, and can suppress abrasion compared with the case where it forms with resin. Note that, instead of the lower guide 41, as shown in FIG. 8, a lower guide 41a in contact with the pocket P1 of the carrier tape P may be adopted.

Above the opening 24c formed in the upper guide 12, as shown in FIG. 1, a camera 42 for imaging the electronic component W sealed in the pocket P1 is provided. Since the cover tape Q has translucency, the camera 42 can image the electronic component W in the pocket P1 through the cover tape Q. The image captured by the camera 42 is given to an information processing unit (not shown), and the information processing unit determines the presence / absence of abnormality of the electronic component W based on the captured image of the camera 42.

Further, below the base unit 15, a moving mechanism 43 for advancing and retracting the base unit 15 is provided. The moving mechanism 43 integrally moves the member attached to the base unit 15 and the mechanism (for example, the pressing member 23, the transport mechanism 11, the upper guide 12 and the push-up mechanism 13) together with the base unit 15 for removal. The pocket P1 from which the electronic component W has been removed by the suction nozzle 22 at the position R can be disposed at the insertion position I.
When the electronic component W is removed from the pocket P1 by the suction nozzle 22, the conveyance of the cover tape Q and the carrier tape P is stopped, and the empty pocket P1 from which the electronic component W is removed is disposed at the insertion position I by the moving mechanism 43. Be done. Then, the electronic component W is put into the empty pocket P1 by the suction nozzle 20.

In the present embodiment, as shown in FIG. 10, the taping device 10 has a disk-shaped rotating body 45 in which a plurality of supporting portions 44 respectively holding the electronic components W are attached to the outer periphery at intervals, and the supporting portions It is used together with an appearance inspection apparatus 48 having

cameras

46 and 47 for imaging the appearance of the electronic component W held at 44 and inspecting the appearance of the electronic component W.
The center of the rotating body 45 is connected to the vertical axis 49, and the rotating body 45 intermittently rotates about the vertical axis 49, and the electronic components W held by the respective support portions 44 can be captured by the

cameras

46, 47. Send to the shooting position of.

Then, the electronic component W determined not to have wrinkles or the like in the appearance is sent to the upper side of the taping device 10 by the rotating body 45 and is held in the pocket P1 of the carrier tape P attached to the taping device 10 by the support portion 44. It is put. The electronic component W determined to have a flaw in appearance is supplied to the sorter 50 provided on the downstream side of the rotational direction of the rotating body 45 of the taping device 10 and discharged as a defective product.

As mentioned above, although embodiment of this invention was described, this invention is not limited to the above-mentioned form, The change of the conditions which do not deviate from a summary, etc. are all the application scopes of this invention.
For example, it is not necessary to provide a warning generation means, and when it is detected that the contact portion is lowered below the lower limit position, only the conveyance of the carrier tape may be stopped, or the carrier tape may be conveyed. It is also possible to record that the contact portion is lowered below the lower limit position without stopping.

Also, an opening through which the cover tape passes may be formed in the upper guide separately from the opening through which the heating portion of the pressing member is passed.
Then, the push-up mechanism only needs to press the tension area from the lower side to the upper guide, and the contact part does not have to contact the tension area from the lower side only on the upstream side of the joining position. For example, the contact portion may contact the tension region from below on the upstream side and downstream side of the joining position, or the contact portion may contact the tension region from below on the downstream side of the joining position.
Furthermore, in the push-up mechanism, application of an upward force to the contact portion is not limited to the elastic body, and for example, a fluid cylinder may be used instead of the elastic body.

Further, in the taping apparatus 10 according to the above-described embodiment, instead of the pressing member 23 pressing the cover tape Q against the carrier tape P, a pressing member contacting the carrier tape P from below and pressing the carrier tape P against the cover tape Q May be adopted.
Furthermore, the adhesion of the carrier tape and the cover tape does not have to be thermocompression bonding, and may be, for example, a cold pressure bonding (pressure-sensitive type) in which pressure is applied under pressure in a normal temperature environment.
Further, the carrier tape and the cover tape do not have to be made of resin, and may be made of paper, for example.
