Abstract

PURPOSE:To position an electronic component accurately with respect to a suction nozzle for a robot by sucking the electronic component, carrying the electronic component from a tray and making the electronic component drop by gravity toward an indentation section approximately coincident with the external shape of the electronic component of a jig installed at a fixed position. CONSTITUTION:A suction nozzle 6 sucks and carries a TAB component 1 (electronic component) housed in a tray, and is stopped in the upper section of a jig 11 and positions the TAB component 1 to the upper section of an indentation section 12. The suction nozzle 6 stops the suction of the TAB component 1 once, and the TAB component 1 is made to drop by gravity. Consequently, the TAB component 1 reaches to the bottom 13 of the indentation section 12 by its own weight and is fitted to the indentation section, and is positioned to the indentation section 12. Accordingly, the TAB component 1 is positioned precisely to the suction nozzle 6.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides (1) a method for positioning electronic components when, for example, electronic components housed in a tray are transported and supplied to a punching die; Regarding.

(Prior Art) Conventionally, an electronic component such as a semiconductor chip has been internally bonded to form a tape carrier and then punched as is using a mold 3. However, both ends of the tape 2 are supported by tape reels (both not shown) for feeding and winding, and the TAB parts 1
... is wrapped in tape 2, so each TAB
Difficult to inspect parts. Therefore, in the method of supplying the tape 2 to the mold 3 directly from the tape reel.

Even if the tape reel contained defective parts, it was sometimes supplied to the mold 3 as is. Also.

In the tape 2 supply method as described above, - type of TAB
It was only compatible with parts, and it was necessary to change the tape reel setup to support other types of TAB parts.

Therefore, each T

Furthermore, as shown in FIG. 5, if the divided TAB parts 1 are stored in the tray 4 in which the parts storage section 4a is divided and then fed to the mold 3, it is possible to The mentioned problems can be solved. In other words, each of the above TAs
When dividing B parts 1..., each part 1... is inspected and non-defective products are selected.

The non-defective products are placed in the component storage section 4a of the tray 4 on a flat surface.

Moreover, by arranging them regularly before supplying them to the mold 3, defective products will not be supplied to the mold 3. moreover,
By storing a plurality of different types of TAB parts in the tray 4 and supplying them to the mold 3, it becomes unnecessary to change the tape reel setup. This makes it easy to attach a wide variety of electronic components to the board when performing outer bonding.

By the way, the divided TAB parts 1... are placed in the tray 4 above.
From there, it is transported to the mold 3 and set on a punching device (not shown) for the parts 1.

If the work of placing the above part 1 on a jig (also not shown) for setting it on the punching device was done manually, it would be time consuming and a lot of time would be spent on this work. It turns out. Therefore.

If the work of transporting and supplying the TAB parts 1 to the mold 3 is carried out using a robot 5 as shown in FIG. 6, the above work can be easily accomplished in a short time. That is, the robot 5 is provided with a head 7 that has a suction nozzle 6 and is movable up and down.

Furthermore, this head 7 is movable back and forth and left and right by means of arms 8, 8 which are perpendicular to each other. and.

The suction nozzle 6 moves as shown by the two-dot chain line in FIG.

However, in order for this robot 5 to work reliably, T
When feeding the AB part 1 to the mold 3, it is necessary that the TAB part 1 be accurately positioned with respect to the suction nozzle 6.

(Problems to be Solved by the Invention) As mentioned above, in order for the robot to pick up the electronic components housed in the tray and supply them to the mold, the electronic components must be accurately positioned with respect to the robot's suction nozzle. It is necessary to be present.

An object of the present invention is to provide a method for accurately positioning electronic components with respect to a suction nozzle of a robot.

[Structure of the invention]

(Means and effects for solving the problem) In order to achieve the above 3φ objectives, the present invention adsorbs electronic components, transports them from a tray, temporarily stops suctioning the electronic components, and installs the electronic components at a predetermined position. The electronic component is allowed to fall naturally toward a recessed part of the jig that substantially matches the outer shape of the electronic component, and the electronic component positioned in the recessed part is again sucked and transported to the mold. There is a particular thing.

By doing so, the present invention is capable of accurately and easily positioning electronic components.

(Example) An example of the present invention will be described below based on the drawings. Further, in the description, the same numbers are given to parts that overlap with the section of the prior art.

FIGS. 1(a) to 1(d) show an embodiment of the present invention, and in each figure, reference numeral 6 represents a cylindrical suction nozzle provided on the head 7 of the robot 5. FIG. This suction nozzle 6 brings its tip into contact with an object to be attracted, and then sucks the object by vacuum suction force or the like. In addition, 1 in each figure is a TAB component as an electronic component divided from tape 2, and 11
is a jig for positioning this TAB part 1.

Here, the jig 11 is transferred from the tray 4 to the mold 3 by the TA.
It is installed in the middle of transporting the B part 1, and its shape is as shown in FIG.

That is, the jig 11 has a concave portion 12 having a rectangular cross section in the center of the surface of a thick plate.

Further, the dimensions of the side wall portion of the bottom portion 13 of this recessed portion 12 approximately match the external dimensions of the TAB component 1 divided into rectangular shapes. In other words, the TAB component 1 is fitted horizontally and in a predetermined direction into the bottom 13 of the recess 12, thereby preventing the TAB component 1 from shifting laterally on the bottom 13. Furthermore, a taper 14 serving as a guide surface is provided at the periphery of the opening of the recessed portion 12. Here, the jig 11 shown in FIGS. 1(a) to 1(d) is in a longitudinally sectional state along the line EE in FIG.

Then, as shown in FIG. 1(a), the suction nozzle 6
picks up and transports the TAB component 1 housed in the tray 4, stops above the jig 11, and positions the TAB component 1 above the recessed portion 12. Next, in Figure 1 (b
), the suction nozzle 6 temporarily stops suctioning the first TAB component and allows the TAB component 1 to fall naturally. therefore.

The TAB component 1 reaches the bottom 13 of the recess 12 due to its own weight, fits into the recess 12, and is positioned relative to the recess 12.

Here, the jig 11 is installed at a position recognized by the robot 5, and thereby the bottom portion 13 of the recessed portion 12 is
The TAB part 1 fitted into the suction nozzle 6 comes to have a predetermined positional relationship with the suction nozzle 6. In other words, the position recognized by the robot 5 is the position where the TAB part 1 fitted into the bottom 13 of the recessed part 12 is positioned with respect to the suction nozzle 6. Therefore, the TAB component 1 is also accurately positioned with respect to the suction nozzle 6.

Note that the above-mentioned predetermined position of the robot 5 can be easily recognized by means such as numerical control.

Furthermore, as shown in FIG. 1(C), the suction nozzle 6 descends to suction the accurately positioned TAB component 1 again, and as shown by arrow C in FIG. 1(d), The nozzle 6 ascends and conveys the TAB part 1 to the mold 3. Then, the TAB part 1 is accurately supplied to the mold 3.

In this way, according to this embodiment, since the TAB part 1 is accurately supplied to the mold 3, the robot can reliably transport and supply the TAB part 1 to the mold 3. therefore.

The work of transporting and supplying the TAB part 1 to the mold 3 can now be carried out without spending too much time and effort, thereby making it possible to reduce production costs.

In addition, in this embodiment, since the taper 14 is provided at the periphery of the opening of the recessed part 12 of the jig 11, even if the TAB part 1 falls with some deviation in the lateral direction with respect to the recessed part 12, The TAB part 1 can be guided by the taper 14 to reach the bottom 13.

In this embodiment, the TAB part 1 is transported and supplied, but the present invention is not limited to the TAB part 1, and any tape carrier that is transported from the tray 4 to the mold 3 may be used. It can also be applied to other electronic components.

〔Effect of the invention〕

As explained above, the present invention attracts electronic components and transports them from a tray, temporarily stops suctioning the electronic components, and creates a recess that substantially matches the external shape of the electronic component on a jig installed at a predetermined position. The electronic component is allowed to fall naturally toward the recess, and the electronic component positioned in the recess is sucked again and conveyed to the mold.

Therefore, the present invention can accurately and accurately manufacture electronic components.

This has the effect of making positioning easier.
