Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a device for adhering a semiconductor chip to a substrate of a lead frame and holding a container containing an adhesive.

[Conventional technology]

 FIG. 2 shows an example of a conventional adhesive container holding device.

The adhesive accommodating container 3 to which the ejection needle 5 for ejecting the adhesive is attached is sandwiched between the fixed portion 1 and the movable portion 2 and fixed by being screwed with the screw 4.

The adhesive is supplied onto the substrate of the lead frame which is continuously transferred under the ejection needle 5. At this time, if the tip of the ejection needle 5 is not always maintained at a fixed position relative to the lead frame, the adhesive position, amount, and spread of the adhesive to be supplied onto the substrate become uneven, which causes a defect. Becomes Therefore, it is necessary to accurately position the tip of the ejection needle 5 in the horizontal (front-back, left-right) direction with respect to the substrate surface and in the vertical (up-down) direction with respect to the substrate surface.

[Problems to be solved by the invention]

When the stored adhesive runs out, it is necessary to replace the container 3. However, in the conventional device, since the container 3 is screwed with the screw 4, the position of the tip of the discharge needle 5 depends on how the screw 4 is tightened. Not only the fluctuation in the vertical direction with respect to the substrate, but also the fluctuation in the horizontal direction. Therefore, it is necessary to adjust the horizontal and vertical positions at the same time each time the replacement is performed, and there is a problem that the position adjustment becomes complicated.

This invention was made to solve the above problems,
An object of the present invention is to provide an adhesive accommodating container holding device that does not require horizontal position adjustment of the position of the tip of the discharge needle 5 when the container 3 is replaced and the tip of the discharge needle 5 is positioned.

[Means for solving problems]

The adhesive storage container holding device according to the present invention is an adhesive storage container holding device for sandwiching an adhesive storage container having an adhesive discharge needle attached thereto, and the tension of a spring stretched between a fixed part and a movable part. , Pressing and sandwiching the adhesive accommodating container, having a rubber plate attached to an adhesive surface between the fixing portion and the movable portion of the adhesive accommodating container, and a guide fixed to the fixing portion, The guide is characterized in that it has a holding portion for holding the tip of the adhesive discharge needle of the adhesive container held between the fixed portion and the movable portion.

[Example of device]

FIG. 1 shows an embodiment of this invention. Figure (a) is a plan view, (b) is a partially cut-away front view, (c) is a bottom view of the guide, and (d) is a partially cut-away front view in which the easy 3 is held. is there.

A rubber plate 6 is attached to the adhesive surface between the fixed portion 1 and the container 3 of the movable portion 2. Fixed pin 8 of fixed part 1 and movable part 2
The spring 7 is hooked between the engaging pins 9 of the
Due to the tension of the container 3, the container 3 is pressed between the fixed portion 1 and the movable portion 2 via the rubber plate 6 and sandwiched. With the container 3 held in close contact between the fixed portion 1 and the movable portion 2 via the rubber plate 6, the tip of the discharge needle 5 is inserted into the hole 11 of the guide 10 attached to the fixed portion 1, and the tip thereof is inserted. Is always adjusted and held in the position of the hole 11. That is, since the horizontal position with respect to the substrate surface does not change, horizontal positioning is not required, and only vertical positioning may be performed.
Positioning in the vertical direction with respect to the substrate surface is performed by adjusting the main body of the adhesive agent applying device to which the holding device is attached.

In addition, when attaching and detaching the container 3, the spring 7
Is extended to widen the gap between the fixed portion 1 and the movable portion 2, and the container 3 is inserted into and removed from the gap, whereby the container 3 can be easily replaced.

[Effect of device]

As described above, according to the present invention, since the guide for horizontally positioning the tip of the discharge needle with respect to the substrate surface is provided, the horizontal position of the tip of the discharge needle varies each time the container is replaced. No horizontal adjustment is required. Also, since the holding method using screws is not used,
This has the effect of facilitating the replacement of the container.
