INDUSTRIAL APPLICABILITY The present invention can provide a storage tape cutting device in which an operator can easily set a storage tape at a position to be cut and the blade is not easily deformed even when dropped.

  Hereinafter, an embossing tape, which is a storage tape 1 for storing electronic components, will be described with reference to FIG. The carrier tape 2 made of a synthetic resin material is formed with receiving recesses 3 with predetermined equal intervals and similarly with feed holes 4 with predetermined equal intervals. The cover tape 5 covers the opening of the storage recess 3 at a position avoiding the feed hole 4 so as to cover the electronic component stored in the storage recess 3.

  The carrier tape 2 contains paint for removing static electricity from the electronic components to be stored, and is colored, for example, black, and the cover tape 5 is made of a transparent synthetic resin material.

  Then, the storage tape 1 is set in a component supply unit (not shown). The storage tape 1 is supplied from a storage tape reel placed on a cart on which a component supply unit is mounted and connected to an electronic component mounting apparatus. The component supply unit intermittently feeds the carrier tape 2 by the tape feeder to the component pick-up position (component suction / extraction position) through the tape path, and electronic components are transferred from the carrier tape 2 with the cover tape 5 peeled off. A suction nozzle (not shown) of the component mounting apparatus picks up and mounts the electronic component on the positioned printed circuit board, and stores the peeled cover tape in the storage portion of the component supply unit.

  Next, the operation when the electronic tape in the storage tape 1 is reduced and the storage tape 1 is cut prior to connecting the new storage tape 1 to the storage tape 1 will be described.

  The storage tape 1 placed on the cart and wound on the storage tape reel that supplied the storage tape to the component supply unit is cut at the boundary position between the position where the electronic component is stored and the position where it is not stored. If it can be done, electronic components will not be wasted. Hereinafter, the cutting apparatus 10 will be described with reference to FIGS.

  The cutting device 10 will be described in detail below. An upper blade body 12 and a lower blade body 13 which are rotatable so as to intersect with each other with a bolt 20 serving as a support shaft, and an upper blade of the upper blade body 12. A protector 14 that protects the upper blade 12A so that the upper blade 12A is not easily deformed even if it extends outward from 12A (beyond the rotation trajectory of the tip of the blade tip) and falls, and the protector 14 is integrated and stored. The support base 16 protruded on the tape support surface 16B for positioning and placing the storage tape 1 formed by recessing the pins 15 and 15 to be fitted into the feed holes 4 of the tape 1 into the upper surface 16A (low step). And a reflecting mirror 17 fixed to the lower surface of the support base 16 with screws 18. The tape support surface 16B makes it easy to align the pins 15 and 15 with the feed hole 4 of the storage tape 1.

  The reflecting mirror 17 extends to the outside of the upper blade body 12 (in the direction opposite to the lower blade body 13), and the upper surface is configured as a mirror surface 17A. The pins 15 and 15 are provided on the carrier tape 2. It is erected on the tape support surface 16B at the same pitch as the pitch of the feed holes 4 or an integer multiple of the pitch of the feed holes 4.

The protective body 14 includes a pivotal support portion 14A through which the bolt 20 is inserted and rotated, and a protective portion 14B that protects the upper blade 12A. The upper blade body 12 and the lower blade body are provided at the upper end of the protective portion 14B. 13 is bent at right angles to the outside along the longitudinal direction of the upper blade 12A at a position above the upper blade 12A in a state where the upper blade 12A is maximally opened to form a bent piece 14C. The protection part 14B is strengthened in terms of strength.

The support base 16 integrated with the protector 14 is formed with an extending portion 16C that extends outward from the lower blade 13A of the lower blade body 13 (frontward from the tip of the blade edge), and the lower surface of the support base 16 is Even if it extends downward from the lower blade 13A and falls, the lower blade 13A is protected from being deformed by preventing the lower blade 13A from coming into direct contact with the ground.

  And the support base 16 which fixed the reflective mirror 17 with the screw | thread 17 on the lower surface, and the protection body 14 are integrated, and the bolt 20 by which the screw thread was formed in the front-end | tip part is inserted in the support base 16 and the protection body 14 To be inserted. Furthermore, the upper blade body 12 and the lower blade body 13 are polymerized so that the screwing hole (screw hole) formed in the upper blade body 12 and the insertion hole formed in the lower blade body 13 are matched. The bolt 20 inserted through the insertion hole formed in the support base 16 and the protection body 14 is inserted into the insertion hole of the lower blade body 13 and screwed into the screw hole of the upper blade body 12, and the nut 21 prevents the bolt 20 from coming off. Has been made.

  Further, a pin 22 is inserted into the lower blade body 13 and the support base 16 so that they are integrated, and a coil spring 23 is provided between the operation portion 12B of the upper blade body 12 and the operation portion 13B of the lower blade body 13. The upper blade body 12 and the lower blade body 13 are biased by the coil spring 23 so as to be separated from each other. However, even if the upper blade body 12 and the lower blade body 13 are separated from each other by the coil spring 23, the separation range is limited by the contact between the stoppers 12C and 13C.

    Accordingly, since the screw thread of the bolt 20 is screwed into the screw hole of the upper blade body 12, the operator resists the urging force of the coil spring 23 and the operator can operate the operation portion 12 </ b> B and the lower blade of the upper blade body 12. When the operation unit 13B of the body 13 is gripped and the operation units 12B and 13B are brought close to each other, the upper blade body 12 is rotated together with the bolt 20 and the lower blade body 13 and the support base 16 are rotated around the bolt 20. Configured.

  Here, cutting is performed using the cutting device 10 at the boundary position between the position where the electronic component of the storage tape 1 in which the remaining number of components supplied to the component supply unit has decreased and the position where the electronic component is not stored, A new storage tape is connected to the cut storage tape 1, and this cutting operation will be described.

  First, the operator fits the feed holes 4, 4 of the storage tape 1 into the pins 15, 15 of the support base 16. In this case, since the storage recess 3 of the storage tape 1 protrudes, the storage recess 3 is placed on the tape support surface 16B, which is a concave surface, so that the cover tape 5 on the flat surface is in contact with the storage recess 3. The feed holes 4 and 4 are fitted to the pins 14 and 14 so that

  At the time of this fitting, an operator sees the inside of the storage recess 3 of the storage tape 1 reflected on the mirror surface 17A of the reflecting mirror 17, and the boundary position between the position where the electronic component is stored and the position where it is not stored The storage tape 1 is fitted on the tape support surface 16B so as to support it. And in this supported state, the operation part 12B of the upper blade body 12 and the operation part 13B of the lower blade body 13 are gripped, and the operation parts 12B and 13B are brought close to each other against the biasing force of the coil spring 21. Then, the upper blade body 12 is rotated together with the bolt 20, and the lower blade body 13 and the support base 16 are rotated around the bolt 20 to cut the storage tape 1.

  In this way, even when the carrier tape 2 is colored black, the position and storage of the electronic components are stored via the transparent cover tape 5 while looking at the storage tape 1 reflected on the reflecting mirror 16. Since it is possible to reliably cut at this boundary position while confirming the boundary position with the position that has not been performed, the electronic component is not wasted.

  Thereafter, a new storage tape that has been cut in the same manner as the cut storage tape is connected to the storage tape 1 that has been cut, and a storage tape reel on which the new storage tape is wound is set on the cart. By doing so, it is used for supplying electronic components.

  In addition, by using a magnifying mirror such as a convex mirror as the reflecting mirror 17, the storage concave portion 3 can be magnified and reflected on the mirror surface, and as a result, the boundary position can be confirmed more easily.

  Even if the cutting device 10 is accidentally dropped along with this cutting operation, the upper blade 12A is protected by the protective portion 14B of the protector 14, and the lower blade 13A is protected by the extending portion 16C of the support base 16. The upper blade 12A and the lower blade 13A are protected from deformation.

  If the component supply unit is attached to the unit base of the electronic component mounting apparatus, the component supply unit is removed from the unit base and moved onto the work table, and the storage tape reel is removed from the unit frame of the component supply unit. The storage tape 1 wound around the storage tape reel may be cut at a boundary position between the position where the electronic component is stored and the position where it is not stored.

  Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description, and the present invention is not limited to the various embodiments described above without departing from the spirit of the present invention. It encompasses alternatives, modifications or variations.
