Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an improvement of a suction table, and more particularly to a device for allocating a suction pad.

<Background of Invention> In the patent application entitled “Suction Table” filed on February 25, 1987, the applicant of the present application applied for an invention having the following points as its gist.

That is, a substrate with a large number of suction holes formed in the thickness direction is fixed on the vacuum chamber of the suction table, and the suction holes of the suction holes that do not require suction force are closed by fitting a closing lid. A suction pad is inserted into the suction holes where force is required to stand upright, and a workpiece is placed on this suction pad and suction-fixed. A cylindrical body having an open end is shown.

In this device, suction pads are inserted upright in the suction holes of the portion that requires suction force, that is, the portion that corresponds to the processed material, and the portion that does not require suction force is mainly the suction hole of the portion that does not correspond to the processed material. Inserts the closing lid and closes.

In this way, the suction hole is divided into a part that requires suction force and a part that does not require suction force.To attach a suction pad to the former and to fit a closing lid on the latter, divide the suction hole into both. You have to do it.

<Purpose and configuration of the invention> The present invention is an allocating device for performing the work of dividing the suction holes as described above, and erection / fitting the suction pad and the closing lid in an efficient and accurate manner. To configure.

That is, a large number of suction holes communicating with the vacuum chamber of the suction table are formed in the substrate fixed on the suction table, and the workpiece is placed on the suction pad inserted into the suction holes and erected and fixed by suction. A table is a device for allocating suction pads in a suction table for a processed material, in which a lower part is inserted into a suction hole, a plurality of columns are erected, and a transparent plate that draws a shape line of the processed material is supported by the columns.

<Operation> Since a transparent plate is provided above the substrate by a column with a space and the shape line of the processed material to be placed on this transparent plate is drawn, the suction hole inside this shape line Inserts a suction pad and fits a closing lid into the suction hole outside the shape line. In this way, the line that divides the suction holes is drawn on the transparent plate, and since there is a space between the substrate and the transparent plate that can be easily touched, the suction pad and the closing lid are aligned along the shape line. If you divide them upright and fit them together, you can perform allocation work efficiently and without error.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings. First, the suction table and the suction pad which are the premise of the present invention will be described. A substrate 1 to be fixed is provided on a suction table (both not shown) having a vacuum chamber, and a number of suction holes 2 communicating with the vacuum chamber are provided in the thickness direction of the substrate 1. Suction hole 2 has a large diameter part (diameter: 28 mm) and a small diameter part (diameter: 20 m)
m) is a vertical hole with a stepped cross section, and the center-to-center pitch of each hole is 44 mm.

A closing lid 3 is fitted into the suction hole 2 of the suction hole 2 which is out of the processed material and does not require a suction force to close the suction hole 2. A suction pad 4 is inserted and installed upright in the suction hole 2 in a portion where a suction force is required in the portion where the processed material is placed. Adsorption pad 4
There is, for example, a cylindrical body having an internal space that communicates in the vertical direction, and the upper open end of which is a suction surface for sucking the processed material. A work material is placed on the suction pad 4, and the work material is suctioned and fixed by the suction force in a vacuum state generated by the operation of the suction table.

In the above suction table, four columns 5 are erected on the substrate 1. The column 5 is a rod-shaped body having an insertion end 6 at the lower end, and is provided with a mounting portion 8 on which the transparent plate 7 described below is mounted by cutting out the upper end at a right angle. The transparent plate 7 is formed of a transparent acrylic material, and a shape line 9 showing the outer shape of the processed material is drawn on the surface thereof.
As for the space between the transparent plate 7 and the substrate 1, put your hands in the suction pad 4
The height that allows easy insertion and removal is set to, for example, 100 mm.

When the above preparation is completed, the suction pad 4 is inserted upright inside the shape line 9 while watching the shape line 9, and the closing lid 3 is fitted on the outside to close the suction hole 2. When the insertion is completed, the transparent plate 7 and the support 5 are removed, and the suction hole 2 after the support 5 is fitted with the closing lid 3 to close the opening. The allocation work is completed.

<Effect of the Invention> As described above, the present invention is composed of the transparent plate that draws the shape line of the processed material and the supporting column that supports the transparent plate, and it is enough to put a hand between the transparent plate and the substrate. There is an interval. Therefore, if the suction pad and the closing lid are separately inserted along the shape line while seeing through the transparent plate from above, the work of allocating the suction pad and the closing lid can be done efficiently and accurately. Is.
