Description

[Detailed description of the invention] [Field of industrial application] The present invention is a thin plate part (hereinafter referred to as a thin workpiece) used in a load beam (spring arm), etc., which supports the magnetic head of a magnetic recording device and has a spring action. The present invention relates to a thin workpiece storage device for storing thin workpieces such as the following:

In order to meet the need for recent magnetic recording devices to be smaller and lighter, ultra-thin sheet metal materials are used for the magnetic head and the like. However, these ultra-thin sheet metal materials (generally
Thin workpieces made of materials (with a thickness of 0.06 to 0.08 mm) are particularly vulnerable to external forces, and are easily damaged if they come into contact with something during the process or during delivery. For this reason, there is a strong demand for the development of a storage device for thin plate parts that is capable of safely and reliably storing thin workpieces between processes.

[Conventional technology]

FIG. 2 is a diagram for explaining a conventional storage device for thin workpieces, in which a is a perspective view of the main part showing the first step during storage, and b is a perspective view of the main part showing the second step. .

As shown in the figure, the conventional storage device is comprised of a head drive shaft 3 having a plurality of suction heads 2, and a conveyance table 4 for transporting a thin workpiece 1 to the operating position of the suction heads 2.

The operation of each of these components will be explained below in accordance with the order of steps.

Figure a shows a state in which the head drive shaft 3 rotates in the direction of arrow A, and the suction head 2 suctions the thin workpiece 1 placed on the conveyance table 4. However, when the head drive shaft 3 and the suction head 2 move from the A' position to the arrow A
While rotating in the direction, the conveyance table 4 is retracted in the direction of arrow B', and after the rotation is completed, it moves in the direction of arrow B to convey the thin workpiece 1 to the operating position of the suction head 2. .

The suction head 2 is structured to be able to suction the thin workpiece 1 by reducing the pressure in the cavity 3' of the head drive shaft 3.

When the suction head 2 suctions the thin workpiece 1, the conveyance table 4 retreats in the direction of arrow B'.

When the conveyance table 4 is retracted, the head drive shaft 3 rotates in the direction of arrow A' as shown in FIG. Due to this rotation, the thin workpiece 1 being sucked by the suction head 2 changes its attitude vertically.

Next, the head drive shaft 3 moves horizontally in the direction of the arrow D-D' to guide the thin workpiece 1 onto a predetermined upper open type notch 6 provided in the case 5. Thereafter, the thin workpiece 1 is vertically lowered in the direction of arrow C and stored in the upper open type notch 6.

When the storage is completed, the reduced pressure of the suction head 2 is released and the thin workpiece 1 is released.

Note that the operations of each of these components are controlled by a control device (not shown).

However, in the conventional storage device described above, the thin workpiece 1 is fixed to the suction head 2 from beginning to end and has no degree of freedom. A contact accident occurs between the case 5 and the case 5, and the delicate thin workpiece 1 is damaged.

When the head drive shaft 3 guides the thin workpiece 1 to the upper open type notch 6 of the case 5, the arrow C--
Since the vertical movement in the C' direction is performed, there is a risk that the thin workpiece 1 will be distorted due to vibration impact during the movement (Note: In this case, the thin workpiece 1 is also completely fixed by the suction head 2. Since it has no freedom at all, it is directly affected by vibration and shock).

There were some basic flaws.

[Problems to be solved by the invention] The invention provides a storage device for thin workpieces that can safely and reliably store fragile workpieces made of ultra-thin sheet metal materials with a thickness of about 0.06 to 0.08mm into a storage case. The purpose is to provide

[Means for solving problems]

The above-mentioned problem is a storage device for storing thin plate parts in a case, and the case has a plurality of pairs of upper open type notches for storing the thin plate parts upright, and the lower part of the case is a work support mechanism having a work support disposed on the side and moving vertically and horizontally relative to the case to store the thin plate part in the case; and a work support mechanism that sucks and rotates the thin plate part. The problem is solved by a storage device for thin plate parts having a mechanism for transferring the thin plate parts at a predetermined position.

[Effect]

The storage device for thin workpieces of the present invention replaces the conventional method of guiding workpieces by moving a head drive shaft with a system installed below the case that picks up the workpieces from below and guides them to a predetermined location. ``It is characterized by an improved structure in which the work is supported by a workpiece support mechanism, and the thin workpiece is not constrained by the workpiece support mechanism during guidance, so the workpiece is The risk of damage to a certain thin workpiece due to external force during movement is completely avoided.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view of essential parts for explaining an embodiment of a storage device for thin workpieces according to the present invention. In the figures, the same reference numerals indicate the same objects.

Since the present invention relates to a partial improvement of a storage device for thin workpieces, we will focus on explaining the improved portion.

As shown in FIG. 1, the storage device of the present invention includes a workpiece support 10 having a pair of support slits 11, an air cylinder 9 for moving the workpiece support 10 in the vertical direction (arrow E-E' direction), and an air cylinder 9 for moving the workpiece support 10 in the vertical direction (in the direction of arrow E-E') cylinder 9
is fixed horizontally along the rail 7 (arrow D-
The slide table 8 is formed to be slidable in the D' direction).

Then, it is attracted to the suction head 2 and the head drive shaft 3
As the thin workpiece 1 is rotated in the direction of the arrow A', the workpiece support 10 rises from below in the direction of the arrow E and receives the thin workpiece 1 into the pair of support slits 11.

At the same time as the above operation is completed, the suction head 2 stops its suction operation, so that the thin workpiece 1 is released from the restraint of the suction head 2 and returns to a free state within the support slit 11.

Since the support slit 11 has a structure that always receives the thin work 1 at a predetermined position and supports it from below, there is no need to forcibly restrain the thin work 1, and it supports it in a free state.

When the thin workpiece 1 is accommodated in the support slit 11, the suction head 2 rotates in the direction of arrow A and becomes ready for the next process.

On the other hand, the workpiece support 10 that supports the thin workpiece 1 and accommodates it in the slit 11 moves in the direction of arrow D-D' and when it reaches the predetermined upper open type notch 6, is lowered in the direction of arrow C by the air cylinder 9. Then, the thin workpiece 1 is accommodated in the upper open type notch 6.

In this way, the thin workpiece storage device of the present invention is
No external force is applied during the storage operation of the thin workpiece 1, and the workpiece support mechanism 20 that guides the thin workpiece 1 operates from below, so that it is installed at a position that does not interfere with the storage process of the thin workpiece. It is distinctive in that it exists.

[Effect of idea]

As explained in detail above, the storage device for thin workpieces according to the present invention prevents the movement of delicate and easily damaged workpieces that are stored in the case by providing a workpiece support mechanism that supports the workpieces from below. It has the effect of being able to be carried out safely and reliably, and is highly effective in storing extremely thin parts.
