A seal tape peeling device 16 includes a vacuum drum 15 that attracts and peels the seal tape 5 of the assembly 1, and a feed claw 17 that moves in a rectangular manner is engaged with a feed hole 7 formed in the side edge of the parts assembly 1. An intermittent transfer device (i
l18, a sensor 19 for detecting the first feed hole 7 of the parts assembly 1, stopping the feed roller 13.13 and switching to transfer by the intermittent transfer device 18; a sensor 19 for detecting the first feed hole 7 of the parts assembly 1; A position regulating means 20 engages with the feed hole 7 to regulate the position of the component assembly 1 when the electronic component 4 is removed from the component storage section 7, and a position regulating means 20 that sucks and takes out the electronic component 4 loaded into the component storage section 3, Pick-up means 21 consisting of a vacuum chuck to be attached to a predetermined position on the substrate are sequentially disposed, and a cutter 22 for cutting the tape body and V-holding tape sent out from this transfer path is also disposed.

The seal tape peeling device 16 includes a discharge means 23 for peeling off the seal tape 5 adsorbed on the vacuum drum 15 from the circumferential surface of the vacuum drum 15 and discharging it, and a force γ tar for cutting the discharged seal tape 5 into short lengths. 24, and a storage box 25 for receiving the cut pieces.

In addition, the intermittent transfer device 18 has an operating plate 26 on which a pair of feed pawls 17 are protruded, attached to the upper end of the output wheel of a solenoid 27 of the upper and lower drive layers, so that the solenoid 27 can be moved in the front and back direction of the transfer path. It is attached to a moving body 28 and is configured to drive this moving body 28 with a Schilling device 29 or a solenoid.
! ! It is configured to move the feeding claw 17 in a rectangular shape by combining the moving and retracting operations of the gear 29. Moreover, the position regulating means 20 is also this intermittent transfer device! ! This configuration is similar to the configuration of No. 18 consisting of an operating plate and a solenoid.

The guide plate covers the upper surface of the parts assembly 1 moving on the road, and the sensor 19 and the pickup means 21 are opened.

In the above configuration, in order to mount the electronic component 4 on the board by rolling up the component assembly 1, the component assembly 1 is wound up and the loop 8 is set on the support means 12, and the component assembly 1 is rolled up. Pull out the tip and insert it between the pair of feed rollers of the feed device 13, then the feed device r! t13 is activated to start feeding out the parts assembly 1, and when the tip of the parts assembly 1 is detected by the sensor 14, the seal tape peeling device 1
Made by 6.

The vacuum drum 15 rotates with a suction function, and the cutter 24 operates. Therefore, when the tip of the parts assembly 1 is located under the vacuum drum 15, the sealing tape 5 is attracted to the vacuum drum 15 and moves to be wound up along the circumferential surface of the vacuum drum 15, while the parts assembly 1 Since the sealing tape 5 continues to move along the transfer route, it is peeled off from the parts assembly 1, further peeled off from the vacuum drum 15 by the discharge means 23, and cut by the cutter 24. It is preferable to remove the sealing tape 5 from the tip of the parts assembly 1 in advance. When the tip of the parts assembly 1 from which the sealing tape 5 has been removed is fed to the position of the transfer device 18, the sensor 19 Detected and sent out device 1

The present invention can be configured in various ways other than those shown in the above embodiments. For example, in the above embodiment, the delivery device 13 and the intermittent transfer device 18 are used together as a means for transferring the parts assembly 1. , a single transport means may be arranged at the beginning of the transport path.

Further, in the seal tape peeling device 16 of the above embodiment, the peeled seal tape 5 is cut by the cutter 24, but it may be collected and discarded as is. Although a type of movement of the pawl 17 in a rectangular shape is illustrated, an intermittent rotating body having a feed pawl around the periphery may be used. In that case, the feed pawl is first aligned with the feed hole 7 of the parts assembly 1. In order to achieve this engagement, it is most reliable to construct this intermittent rotating body so that it can be moved up and down.

Effects of the Invention Since the present invention has the above configuration, when replacing the parts assembly with a new part assembly, all that is required is to set the reel on which the parts assembly has been wound up and transport it by the transport means, and during the transport, The seal tape can be adsorbed and peeled off using a vacuum drum. Since there is no need to set one part on a winding device or the like, the time required to replace the parts assembly can be significantly reduced, and the non-operating time can be reduced accordingly. Furthermore, since the replacement work is simple, automation is also possible. Furthermore, since the parts assembly can be supplied in the form of just being wound onto a reel, it is lightweight and inexpensive, and there is no need for any extra effort.
