2. Description of the Related Art TAB (Tape Automated)
Electronic components obtained by the Bonding method have been increasingly used in various devices in recent years because they have a small thickness and a high degree of integration. The TAB method is a method in which leads and chips cut out of a wafer are bonded to the surface of a film carrier made of a synthetic resin tape, and the film carrier is punched by a punching device to obtain electronic components.

[0003]

The film carrier comprises:
It is supplied in a form wound on a supply reel with separators interposed therebetween alternately. However, depending on the type of supply reel, the winding order of the film carrier and the separator is different, and the conventional electronic component supply device cannot cope with the change of the winding order, so the entire feed mechanism has to be replaced. I was

Accordingly, an object of the present invention is to provide a method of supplying an electronic component that can smoothly cope with the same apparatus even if the winding order of a film carrier and a separator is changed.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of an electronic component supply device according to an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a main body frame;
The components described below are assembled. Reference numeral 2 denotes a supply reel rotatably mounted on the upper portion of the main body frame 1, and a film carrier 3 and a separator 4 are wound alternately. Here, the winding order of the film carrier 3 and the separator 4 differs depending on the type of the supply reel 2. Reference numeral 5 denotes a take-up reel rotatably mounted below the supply reel 2, and takes up the separator 4 fed from the supply reel 2. The take-up reel 5 corresponds to a separator collecting means. 6
Is a guide roller for guiding the transport of the separator 4.
M <b> 1 is a first motor that can perform normal rotation and reverse rotation, and rotates the supply reel 2 by the belt 7. The take-up reel 5 rotates by being driven by the first motor M1. The first motor M1 corresponds to the drawing means.

On the left side of the main body frame 1, an upper die 8 and a lower die 9 constituting a punching portion are arranged. The film carrier 3 positioned between the upper die 8 and the lower die 9 is punched by the upper die 8 being driven up and down by being driven by the cylinder 10.

[0010] A tension roller 11 is provided between the supply reel 2 and the take-up reel 5. Reference numeral 12 denotes a cylinder, which is disposed in a horizontal posture and has a rod 1
A tension roller 11 is supported at the distal end of the third roller 3 so as to be movable in the horizontal direction. Reference numeral 14 denotes a guide portion of the tension roller 11. The film carrier 3 fed from the supply reel 2 circulates around the tension roller 11, turns in the horizontal direction, and is sent between the upper die 8 and the lower die 9. When the rod 13 of the cylinder 12 protrudes rightward, the tension roller 11 is urged rightward to apply tension to the film carrier 3. That is, the cylinder 12 serves as urging means for the tension roller 11. As the urging means, a means for urging the tension roller 11 rightward with a spring material such as a coil spring may be used. However, when the spring material expands and contracts, the spring force fluctuates and the urging force of the tension roller 11 changes. There is. On the other hand, if the cylinder 12 is used as in the present embodiment, a constant tension can always be applied even if the position of the tension roller 11 changes in the horizontal direction.

A dog 15 is provided above the tension roller 11.
Is provided. A first sensor 16 and a second sensor 17 are provided on both sides of the dog 15. The first sensor 16 detects a rightward movement limit of the tension roller 11, and the second sensor 17 detects a leftward movement limit. Reference numeral 18 denotes a driven sprocket provided on the right side of the upper die 8 and the lower die 9, and the film carrier 3 is horizontally adjusted between the tension roller 11 and the driven sprocket 18. M2 is a second motor, and a belt 19
To rotate the drive sprocket 20 and rotate the collection reel 21 as a film carrier collection unit. The second motor M2 and the driving sprocket 20 correspond to a feed mechanism for feeding the film carrier 3. As the collecting means, it is not necessary to wind the separately punched film carrier 3, and a collecting box or a film carrier to be collected in a solid state may be cut and collected.

Reference numeral 22 denotes a pressing roller for pressing the film carrier 3 against the driving sprocket 20. The film carrier 3 that has circulated around the driving sprocket 20 is taken up and collected by a collecting reel 21 disposed above the film carrier 3. In the driven sprocket 18, the pins protruding from the peripheral surface of the driven sprocket 18 are fitted into pin holes opened along both sides of the film carrier 3 along the longitudinal direction, so that the film carrier 3 is moved in the width direction. To prevent it from bending
The flatness of the film carrier 3 is maintained so that the upper die 8 and the lower die 9 can be punched out with higher precision. Reference numeral 23 denotes a camera provided below the transport path of the film carrier 3 for observing the film carrier 3 and detecting its position.

FIG. 2 is a block diagram of an electronic component supply device according to one embodiment of the present invention. In FIG. 2, 24 is a CPU.
(Central processing unit) and ROM for storing control programs
A control unit 25 comprising a (read only memory) is a forward / reverse setting switch corresponding to a means for switching the rotation direction of the first motor M1. Of course, the forward / reverse setting switch 25
It may be a software switch on the control program or a mechanical switch such as a button switch.

Next, the operation of the electronic component supply device of the present embodiment will be described with reference to FIG. In FIG. 1, the supply reel 2
Shows the operation in the case where the winding order is such that the film carrier 3 is on the outer side and the separator 4 is on the inner side in the outermost peripheral portion. At this time, the operator sets “forward rotation” using the forward / reverse setting switch 25. Then, the control unit 24 controls the first motor M1
To rotate the supply reel 2 in the direction of the arrow N1. Here, the film carrier 3 goes around the tension roller 11 and reaches between the upper die 8 and the lower die 9, and the upper die 8 and the lower die 9 punch out electronic components from the film carrier 3 and collect the film carrier 3. It is wound up on the reel 21 and collected. On the other hand, the separator 4 is collected by the take-up reel 5 rotating in the direction of the arrow N2 via the guide roller 6.

FIG. 3 is a diagram for explaining the operation of the electronic component supply device according to one embodiment of the present invention. Next, contrary to FIG. 1, the supply reel 2 in the winding order in which the film carrier tape 3 is inside and the separator 4 is outside at the outermost periphery,
When the operator sets “reverse rotation” with the forward / reverse rotation setting switch 25, the control unit 24 causes the first motor M1 to rotate in the reverse direction. As a result, contrary to FIG. 1, the supply reel 2 rotates in the direction of arrow N3, and the take-up reel 5 rotates in the direction of arrow N4. The other operations are the same as those shown in FIG.

[0016]

According to the present invention , when the winding order of the film carrier and the separator is changed, the rotation direction of the motor and the rotation direction of the supply reel are reversed, so that the same apparatus can smoothly cope.
