Description

Feeding and cutting apparatus of feeding tape of attachment electronic parts

The present invention relates to a transfer and cutting device for an electronic component mounting transfer tape which is capable of automatically cutting and cutting a roll type transfer tape for transferring an electronic component for mounting a surface to a mounting machine.

More specifically, the transfer tape is used to transfer the surface mount electronic components individually received to the mounter, and then the upper and lower portions of the transfer tape continuously transferred by the transfer means are pressed to maintain tension. The present invention relates to a transfer and cutting device for a transfer tape for mounting electronic components, which enables the transfer tape to be automatically cut by a cutter.

The above-mentioned "transfer tape" is used to continuously transfer the electronic components to the mounter from an accommodating portion formed so that the electronic components (semiconductor chips, integrated circuit devices (ICs), etc.) are individually received. It refers to a tape (referred to the waste paper is disposed of waste paper) containing a cover vinyl (referred to as waste vinyl), which is wound around.

As shown in FIG. 1, the roll-type transfer tape for conveying the surface-mounted electronic parts, which are separately contained and sealed, into the mounter includes grooves 2 to separate and receive the electronic parts 1, respectively. ) Is formed at equal intervals, and is sealed by a cover vinyl (3) to prevent separation of the electronic component (1) housed in the groove (2) and to protect it from contamination sources such as dust, and the groove (2) Index holes 5 are formed at equal intervals so as to transfer the conveying tape 4 to one side at a uniform speed.

As shown in FIG. 2, the electronic component transfer tape cutting device according to the prior art is disclosed in an external tape cutter device for an electronic component mounting machine of Korean Patent Application No. 1998-3032.

The cutting device of the prior art includes a main body 11 having a funnel-shaped insertion opening 2a arranged in parallel on an upper surface thereof so that a plurality of transfer tapes t1 can be introduced at the same time;

Safety cover to protect the worker's hands.

Hereinafter, with reference to the accompanying drawings an example of the use of the transfer and cutting device of the transfer tape for mounting electronic components according to an embodiment of the present invention will be described in detail.

As shown in Fig. 8 and Fig. 10, the feed tape 50 which seals the surface mount electronic component 80 which is individually isolated and received by the vinyl tape 90 is fed by the feeder 76. It is continuously moved to the mounting apparatus 77 side. That is, the conveying tape 50 wound on the reel 78 in the form of a roll is released from the reel 78 and moved to the mounter 77 side by the separator 79 formed on the upper part of the feeder 76. ) And release paper 81 is separated. At this time, the vinyl tape 91 is pulled by a pair of toothed drive reels 82, and the release paper 81 is moved below the feeder 76 along the moving passage 83 in the drawing.

On the other hand, a transfer apparatus including a feeder 76 for continuously transferring the above-described transfer tape 50 (consisting of the vinyl tape 90 and the release paper 81) to the mounting machine 77 side, and the mounting machine 77 The detailed description of the fixing device (not shown) for fixing the electronic component 80 supplied to the printed circuit board (not shown), etc. is included in the technical details used in the art, and their construction and operation Detailed descriptions thereof will be omitted.

The transfer tape 50 separated by the above-described separator 79 into the vinyl tape 90 and the release paper 81 is moved toward the inlet 51 formed on the upper surface of the main body 53.

As shown in FIG. 5, the transfer tape 50 supplied into the main body 53 through the inlet 51 is provided with a pair of brushes 55 and 56 which are opposed to each other in the longitudinal direction under the inlet 51. It is pulled toward the inner bottom surface of the main body 53 by rotation. At this time, since the rotational force transmitted from the driving motor 54 is transmitted to the driving gear 73-driven gears 74 and 75 to be engaged, the brushes 55 and 56 are rotated in opposite directions.

Accordingly, the transfer tape 50 introduced into the inlet 51 may pass through a pair of brushes 55 and 56 that are engaged with each other and rotated in opposite directions.

As shown in Figs. 4 and 7 (a), a transfer tape 50 (consisting of a vinyl tape 90 and a release paper 81) passing through the brushes 55 and 56 described above is used as a brush 55 and 56. Pass through the guider 67 installed below) is passed between the support member 57 and the pressing member 59. At this time, the pressing member 59 installed in the frame 60 moved by the driving unit (for example, an air cylinder not shown) may be used to maintain a stopped initial state.

As shown in Figure 4 and 7 (b), due to the air cylinder (not shown) driving a plurality of pressurized integrally fixed to the frame 60 as the frame 60 is moved to the left in the drawing The member 59 (9 as an example is shown in the figure) is moved towards the backing member 57. That is, the transfer tape 50 is fixed between the supporting member 57 and the pressing member 59 which are mutually compressed to maintain the tension.

At this time, the cutter 61 integrally fixed to the above-described frame 60 maintains a predetermined distance away from the transfer tape 50.

At this time, when fixing the transfer tape 50 to maintain the tension by the mutual compression of the support member 57 and the pressure member 59 described above, the cap of the poly urethane carbon material coupled to the outer surface of the pressure member 59 By 62, the frictional force of the pressing member 59 against the support member 57 can be increased. Therefore, it is possible to prevent the transfer tape 50 from slipping when the transfer tape 50 is cut by the cutter 61.

Further, the pressing force of the pressing member 59 against the supporting member 57 is increased by the inclined surfaces 63 and 64 formed on the outer surface of the cap 62 of the supporting member 57 and the pressing member 59. You can. Therefore, the feed tape 50 can be cut by the cutter 61 in a stable state, thereby preventing slipping of the feed tape 50.

As shown in Fig. 4 and 7 (c), in the state in which the pressing member 59 is pressed against the support member 57 by the above-described air cylinder (not shown) driving, the extension driving amount of the air cylinder In the case of a slight increase, the frame 60 is slightly moved leftward in the drawing. Therefore, the transfer tape 50 can be cut by the cutter 61 fixed integrally to the frame 60.

At this time, since the pressing member 59 is continuously pushed against the supporting member 57 by the movement of the frame 60, the transfer tape 50 may maintain a predetermined tension. That is, since the pressure of the air cylinder for moving the frame 60 is increased, the first pressing pin 68 of the pressing member 59 overcomes the elastic force of the elastic member 69 in the frame 60 and the inside of the frame 60. It flows in a certain amount.

Therefore, the conveying tape 50 is smoothly cut by the cutter 61 in a state where the conveying tape 50 is fixed while maintaining the tension due to the mutual crimping of the supporting member 57 and the pressing member 59 described above. can do.

On the other hand, although not shown in the drawings, the vinyl tape 90 and the release paper 81 constituting the above-described transfer tape 50 is required to collect separately (vinyl tape 90 and the release paper 81 of the material is Differently, when separate collection is required), the pair of main bodies 53 can be disposed in parallel to transfer and cut the vinyl tape 90 and the release paper 81 separately for disposal.

As shown in FIG. 9, when the pressing members 59 which are moved toward the supporting member 57 and press-fix the transfer tape 50 are arranged in a group and are laterally spaced apart (for example, in FIG. 6 Two pressing members are shown), each of the pressing members 59 may be simultaneously pressed by the cam plate 71 slidingly moved according to the driving of the air cylinder 72. This reduces the number of parts and reduces cost and assembly costs.
