is a rod-shaped magnetic workpiece (hereinafter referred to as slug lead), which consists of a long rod-shaped lead part 2, 2 and a cylindrical slug part 3, 3 with a larger diameter than the lead parts 2, 2, and at least the lead The parts 2, 2 are made of magnetic material, for example, Fe--Ni alloy. 4 is a semiconductor pellet held between the slugs 3, 3 of the slag leads 1, 1, and 5 is a lead glass welded to the outer circumferential surface of the slug parts 3, 3 holding the semiconductor pellet 4 to hermetically seal the inside thereof. Made of glass sleeve.

In manufacturing the above DHD type diode, the slug leads 1, 1... are stored in a large number (for example, 500 pieces) in a work storage container as described below, and transported or stored in that state. Common.

As shown in FIG. 7, the workpiece storage container 6 includes a bottomed cylindrical container body (hereinafter referred to as a bobbin) 7 and a lid body (hereinafter referred to as a cap) 8 for fitting the opening. Then, put slug lead 1 on bobbin 7,
A large number of books 1... are stored at once, and the caps 8 are used to fit them. In the manufacturing process of DHD type diodes, the slag leads 1, 1... are taken out from the workpiece storage container 6, a large number of slag leads 1, 1... are transferred to an alignment jig, etc., and then the semiconductor A large number of DHD type diodes are manufactured by heating the pellets 4 and glass sleeves 5 arranged as shown in FIG. 6.

Problems to be Solved by the Invention Incidentally, in order to take out the slag leads 1, 1, . Conventionally, the work of extracting the caps 8 was performed by an operator while grasping the bobbin 7 of each workpiece storage container 6.
There is a problem in that it takes a lot of time to remove the caps from a large number of work storage containers 6, and the work efficiency is significantly reduced.

Therefore, an object of the present invention is to automatically perform the work of removing the caps from the workpiece storage container by batch processing.

Means for Solving the Problems The present invention was proposed in view of the above-mentioned problems, and includes a large number of workpiece storage containers that store a large number of rod-shaped magnetic workpieces and whose openings are covered with lids. a base in which the pieces are arranged in an array; a magnetic attraction means arranged below the base for magnetically attracting the magnetic workpieces through the workpiece storage container on the base; and a lid for each workpiece storage container above the base. The above-mentioned problem is solved by providing a lid removal device comprising vacuum suction means having suction pads that are arranged opposite to each other and vacuum suction pads for vacuum suctioning the lid.

Function The present invention, like the above-mentioned means, arranges a large number of work storage containers in which a large number of rod-shaped magnetic slag leads are collectively arranged on a base, and operates the magnetic attraction means as appropriate. The bobbin is fixedly placed on the base by magnetically attracting the slag lead, and from this state, the caps are vacuum suctioned by the suction pad of the vacuum suction means, and a large number of caps are pulled out from the bobbin at once.

Embodiment An embodiment of the lid removal device according to the present invention will be described with reference to FIGS. 1 to 5. However, the same parts as in FIGS. 6 and 7 are given the same reference numerals, and explanations thereof will be omitted. As shown in FIGS. 1 and 2, the lid removal device 10 according to the present invention includes a base 11
a base 12 fixedly arranged on the base 12;
A magnetic attraction means (hereinafter referred to as a magnetic plate) 13 arranged vertically movably below the base 1
2, and a vacuum suction means 14 arranged vertically movably above the vacuum suction means 2.

The base 12 has a box-like tray shape that opens upward, and a third workpiece storage container 6, in which a large number of slug leads 1, 1, . . .
As shown in the figure, a large number (81 in the figure) are efficiently arranged and placed at predetermined positions on the base 11.

As shown in FIG. 4, the magnetic plate 13 has magnets 15, 15, . It is disposed below the base 12 via a cam lever 17 so as to be vertically movable.

The magnetic force of the magnetic plate 13 needs only to be strong enough to act on the slug leads 1, 1, . If it's too strong,
The slag leads themselves become strongly magnetized, and the slag leads 1, 1... themselves are magnetic and repel each other, causing problems in handling.

The vacuum suction means 14 has a hollow box shape as shown in FIGS.
Vacuum adsorption unit 19 in which 8, 18... are formed
and holes 18, 1 on the bottom surface of the vacuum suction unit 19.
Suction pads 20, 20, . It consists of a vacuum suction machine 21 that evacuates the internal space. Furthermore, the vacuum suction unit 19 is suspended from a mounting plate 24 via two guide rods 22, 22 so as to be vertically movable by an air cylinder 23, and the mounting plate 24 is horizontally movable via slide shafts 25, 25. It is freely arranged. Also, 26 is the suction pad 2
This is a chute for transporting the caps 8, 8, . . . attached to the caps 0, 20, .

Next, the lid removal device 1 configured as described above
The operation of 0 will be explained with reference to FIG. When the base 12 is placed at a predetermined position on the base 11 and the magnet plate 13 is raised via the cam lever 16 to the position shown by the imaginary line in the figure, the slug leads 1, 1
The magnetic fields of the magnets 15, 15... act on ..., and the slug leads 1, 1... are magnetically attracted to the bobbin 7.
is fixed on the base 12. From this state, the suction pad 20 disposed above the base 12 is lowered and pressed slightly, and the vacuum suction device 21 is activated to suction the cap 8 under vacuum. And suction pad 20
When the bobbin 7 is fixed on the base 12, only the cap 8 is removed.
The extracted cap 8 is conveyed to the upper part of the chute 26, and by cutting off the suction of the vacuum suction machine 21, the cap 8 is transferred from the suction pad 20 to the chute 26. Further, the bobbin 7 from which the cap 8 has been removed is returned to its original position via the cam lever 16 to weaken the effect of the magnetic field, and then the bobbin 7 and the base 12 are transported out together.

In addition, in the above example, the case where it was applied in the manufacture of a DHD type diode was explained, but
The present invention is not limited to this, that is,
It is sufficient that the workpiece is rod-shaped and made of a magnetic material, and the magnetic attraction means and vacuum attraction means are of course not limited to the above-mentioned structure.

Effects of the Invention According to the lid extracting device of the present invention, it is possible to automatically extract a large number of caps from a workpiece storage container at the same time, thereby significantly improving work efficiency. Further, since the above object can be achieved with a simple configuration of the magnetic attraction means and the vacuum suction means, it is possible to provide an apparatus which is very advantageous in terms of equipment.
