Abstract

PURPOSE:To stably feed electronic parts by independently pressing two positions directly before and after the part taking-out position by a guide bar and setting the stripping-off position for a covering tape in the intermediate part between the concaved parts for accommodating the parts on an accommodated tape. CONSTITUTION:Two positions on an accommodated tape 1, directly namely the positions before and after the part taking-out position are pressed by a guide cover 9 and a tape guide 11. Said tape guide 11 is freely opened and closed by a lever. Further, according to the relation between the stripping-off position for the covering tape 3 for the accommodated tape 1 and the guide cover 9, the trouble of lateral erection, reversal, etc. of the parts due to the initial vibration can be suppressed by forming a stripping-off window 18 for the covering tape 3 for the guide cover 9 at the intermediate part between the concaved parts 16 and 17 of the accommodated tape 1, since the upper part of the electronic part 2 is covered by the covering tape 3 when the feed of the accommodated tape 1 is started, and the feed of the electronic parts 2 in the regular stable state is permitted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus for supplying electronic components, and more particularly to an apparatus for continuously supplying a series of a plurality of leadless microelectronic components.

Conventional Structure and Problems Conventionally, leadless type microelectronic components (hereinafter referred to as chip type electronic components) are supplied using a strip-shaped long material such as tape (hereinafter referred to as The supply form is an electronic component assembly in which chip-type electronic components 2 are placed on a storage tape (1). A covering tape 4 to prevent the chip-type electronic components 2 from falling off is pasted onto the storage tape 1 in a way that it is lightly combed, and is placed at a predetermined position on the guide cover 4 to prevent the tape from lifting. , the covering tape 4 is peeled off from the storage tape 1.

Furthermore, the position at which the vacuum chuck 5 takes out the parts is earlier than the center of the wheel 6 for feeding the storage tape 1 at a predetermined pitch.

However, since the guide cover 4 presses the storage tape almost on the center of the wheel 6, the storage tape 1 is not securely pressed before and after the parts removal position, so the storage tape 1 may lift up, bend, etc. ,
Parts become unstable.

Furthermore, as shown in FIG. 2a, since the opening position of the covering tape 3 is just before or in the recess where the components of the storage tape 1 are stored, the inertia of the electronic components and the static electricity of the covering tape are In addition to pulling up the parts in the peeling direction, the initial vibration at the start of feeding the storage tape causes the storage tape 1 to
The concave circle causes unstable conditions such as parts standing sideways and parts upside down, which causes mistakes in taking out parts and mistakes in mounting them on the board.

Also, when replacing the storage tape 1 to the electronic component supply device 7,
As in the conventional example shown in Figure 2, the tape must be inserted between the lower fixed tape guide 1o and the tape feed wheel 6 while the guide covers 8 and 9 are lifted by hand against the spring force. However, the disadvantage is that it takes a very long time.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned problems, and aims to make it possible to stably supply electronic components and shorten the time required to replace storage tapes.

Structure of the Invention In order to achieve the above object, the present invention provides that a guide cover for holding and regulating a storage tape is installed at a position 2 immediately before and after a component extraction position.
This is an electronic component supply device which has a configuration in which the parts of the storage tape are held down independently, can be opened and closed by levers, and the position where the covering tape is removed is approximately halfway between the recesses in which the parts of the storage tape are stored.

DESCRIPTION OF EMBODIMENTS An embodiment of the method of the present invention will be described below with reference to FIGS. 3 to 7. Guide cover9. The tape guide 11 is configured to press the storage tape 1 at two locations immediately before and after the component extraction position, and the tape guide 11 can be opened and closed by a lever 12. FIG. 4 shows that the tape guide 11 is opened by pushing up the lever 12, and the recess 13 of the lever 712 is opened.
When the pin 14 is caught on the tape guide 11
Figure 6 shows the state in which the lever 12 is pushed down, the pin 14 is removed from the recess 13 of the lever 12, the tape guide 11 is pushed down by the spring 15, and the floating of the storage tape 1 is controlled. be. Furthermore, the positional relationship between the cover tape 3 of the storage tape 1 and the guide cover 9 is approximately halfway between the recess 1 (16) and the recess 2 (17) of the storage tape 1, as shown in FIG. Covering tape 3 Rehabilitation window 1 of guide cover 9
8, when the storage tape 1 starts feeding, the upper part of the electronic component 2 is covered with the covering tape 3, so there is no problem such as the component standing sideways 1 reversed due to initial vibration, and the normal stable state is maintained. It is possible to supply electronic components 2 at

Effects of the Invention As described above, according to the present invention, the guide cover for holding and regulating the storage tape is configured to press independently at two locations, immediately before and after the parts removal position, and when the storage tape starts feeding 9. The structure is not affected by initial vibrations, and the guide cover can be opened and closed using a lever.
This makes it possible to improve the reliability of continuous and stable supply of parts, shorten the time required to replace storage tapes, and quickly respond to changes in electronic component types.
