Description

[Detailed Description of the Invention] The present invention relates to a device for transporting magnetic materials such as iron, nickel, and iron alloys that can be attached by magnetic force. Relates to a device suitable for transporting objects attached to it.

For example, magnetic materials 1 such as lead frames for semiconductor integrated circuits, nickel gold casting foils, metal stencils for screen printing, fine mesh products, or thin sheet metal etching parts are treated with various processing liquids during manufacture and use. (for example, etching solution, plating solution), cleaning solution, etc., often make the surface wet. Even if an attempt is made to transport such a magnetic material 1 to the next process location using an electromagnetic transport device, as shown in FIG. It sticks to the underside of arm 2 and does not come off even if the electromagnet's current is cut off to eliminate the magnetic field.

The present invention is a conveyance device that does not cause the above-mentioned problems, and will be explained below based on drawings showing embodiments. That is, in the conveying device as shown in FIG. 2, the conveying arm 5 equipped with the electromagnet 4 is moved vertically and vertically with respect to the fixed frame 8 of the conveying device by the lift cylinder 6 and the traverse cylinder 7. It reciprocates in a direction perpendicular to the plane of the paper in Figure 2. In the figure, the vertical movement of the transport arm 5 is regulated by a joint spacer 10 that is slidably fitted with a lift rail liner 9 on the lift cylinder 6 side, and similarly, a fixed frame 8
Movement in the direction perpendicular to the plane of the paper is also restricted by the LM guide 12 that is slidably fitted to the side LM guide track 11. In the conveying device as shown in FIG. 2, an interposer 13 is arranged to maintain a constant distance between the electromagnet 4 installed in the conveying arm 5 and the magnetic material 1 to be conveyed, and An interposer 14 having a shape that makes point contact with the magnetic body 1 is further provided below the interposer 13.

Further explanation based on Figures 3 and 4 of the drawings:
The interposer 13 is made of glass, plastic, or a material that is not magnetized, and the magnetic material 1 to be transported by the residual magnetic force remaining after the current of the electromagnet 4 is released.
In order to prevent the electromagnet 4 from being retained, an interposer 13 of an appropriate thickness is provided immediately below the electromagnet 4. Further, the interposer 13 is a processing/etching solution, a coating solution, a cleaning solution, etc. that adheres to the surface of the magnetic body 1, and many of them have radical properties. In order to prevent the electromagnet 4 and the transport arm 5 from being attacked by -, the lower surface of the electromagnet 4 is provided so as to be covered.

The interpolator 14 may be formed by attaching a rod-like object 15 directly below the interposer 13, as shown in FIG. For example, the body may be attached directly below the interposer 13, but any other method that can realize line or point contact may be adopted.

However, as shown in the figure, in order to ensure the detachment of the thin plate-shaped magnetic body 1, instead of supporting the magnetic body 1 horizontally, it must be kept in a slightly inclined state while making contact with the intercalator 14. It is appropriate to do so. In order to do this, the diameter of the bar 15 at the center of the interpolator 14 is made larger than the other diameters, or the top of the chevron 16 provided at the center or near the end 14' is set to a different chevron. This can be achieved by making the structure higher.

The present invention is as described above, and according to the conveying device of the present invention, (1) Since it is a point contact, the surface tension of the liquid attached to the surface of the magnetic material is difficult to act on, and therefore the magnetic field is Detachment after being erased occurs without any hindrance.

(2) The interposer eliminates the effects of residual magnetic force and prevents the carrier from being attacked by liquid adhering to the surface of the magnetic material.

(3) In particular, when using an intercalator that holds the magnetic material not horizontally but at a slight angle, one side of the magnetic material may end up floating in the air. However, the surface tension caused by the liquid does not work very easily, and the desorption process occurs without any malfunction.

There is an effect.
