Abstract

PURPOSE:To enable fine movement of a member for positioning, by a method wherein a member is held by raising a floating mechanism by means of an elevating mechanism, and an arm driving mechanism is driven so that the member so held is brought into contact with a fixed pin. CONSTITUTION:When a member 5 is conveyed by means of a conveyor line 9, a table 4 is in a lowered state and an arm 6 is also in a non-protruded state. When the member 5 is conveyed to a given spot and running of the conveyor line 9 is stopped, the table 4 is raised, and the member 5 is lifted up from the conveyor line 9 by means of an attachment 2A. Through protrusion of the arm 6, the side wall of the member 5 is pressed in a manner that the side wall is brought into contact with the tip part of a fixed pin 3, and the member 5 is positioned in a place. In this case, movement of the member 5 is effected by a floating mechanism 2, and thereby is performed with soft touch.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Summary] Processing 2 A member to be assembled or tested is held by an attachment of a floating mechanism, and a predetermined part of the member is brought into contact with a fixing pin by an arm. By moving the member in this way, frictional movement can be avoided and the member can be accurately positioned.

[Industrial application field]

The present invention relates to a positioning device for positioning a member to be processed, assembled or tested at a predetermined location, and in particular, the present invention is formed so that frictional movement is reduced and accurate positioning is possible by holding the member by a floating mechanism. The present invention relates to a positioning device.

When manufacturing products using a conveyor line, multiple stations are arranged along the traveling line of the conveyor line, and each stage is equipped with equipment for processing, assembly, or testing. be done.

Therefore, the members to be assembled or tested are loaded onto a conveyor line and transferred, and then assembled or tested using a predetermined device at each stage.

Therefore, in order to carry out such machining or testing, it is important that the transported members are accurately stopped at predetermined positions on each stationary run.

When such a conveyor line is used as a production line for semiconductor devices, etc., the above-mentioned stopping position accuracy is high,
Furthermore, since the installation will be carried out in a clean room, it is desirable that no dust be generated.

[Conventional technology]

Conventionally, the configuration was as shown in the conventional explanatory diagram of FIG. 4. FIG. 4(a) is a plan view, and FIG. 4(b) is a side view.

As shown in FIG. 4(a), the conveyor line 12 has a belt lO stretched so as to run in the direction of the arrow;
A stopper 14 is provided on one of the guardrails 11 and is rotated by a pin 13.

Therefore, the members 5 to be processed, assembled or tested are locked on the pallet 16, and the pallet 16 is loaded on the belt 10 and transported by the drive of the belt 10. When the pallet 16 reaches a predetermined location, the belt 10 The drive is stopped, and the stopper 14 is manually rotated in the direction of arrow B as shown in FIG.
The pallet 16 was positioned at a predetermined location by bringing the stopper 14 into contact with the pallet 16.

[Problem that the invention seeks to solve]

However, such a configuration requires manual labor to rotate the stopper 14, and the stopping position of the bell 10 is not the same as that of the stopper 1.
If the contact position of 4 does not match, it is necessary to adjust the position, and in this case, the contact part between the baren 16 and the belt 10 will be rubbed, causing the problem that metal powder etc. will be generated. .

In addition, in positioning using such a stopper 14, the member 5 is directly attached to the belt 1 so as not to damage the member 5.
0, so be sure to use a dedicated baren)
I had the problem of having to prepare 16.

(Means for solving problems) FIG. 1 is a diagram showing the principle configuration of the present invention.

As shown in Figure 1, processing is performed by being lifted up.

A floating mechanism (2) having an attachment (two people) that holds a member (5) to be assembled or tested, a fixing pin (3) that abuts on a predetermined location of the member (5), and the floating mechanism ( 2) and a lifting mechanism (1) that lifts and lowers a table (4) loaded with the fixing pin (3);
an arm mechanism (for driving an arm (6) that protrudes so that a predetermined portion of the member (5) comes into contact with the fixing pin (3);
7), and a control section (8) that controls the lifting mechanism (1) and the arm mechanism (7).

With this configuration, the above-mentioned problems are solved.

[For production]

That is, the floating mechanism is raised by the lifting mechanism to hold the member, the arm drive mechanism is driven so that the held member comes into contact with the fixed pin, and positioning is performed by controlling the movement of the member. It is designed so that it can be

Therefore, when moving for positioning, it is possible to move by soft touch, and the frictional movement can be minimized, so there is no need to use a pallet as in the past (members can be handled directly, eliminating the need for a pallet).

Further, fine movement for positioning becomes easy, and positioning accuracy can be improved.

(Example) The present invention will be explained in detail below with reference to Fig. 2 and Fig. 3. Fig. 2 is an explanatory diagram of an embodiment according to the present invention, and (a)
is a configuration diagram, (bl) (cl) is a plan view, (b2) (C2
) is a side view, and FIG. 3 is a side view of the floating mechanism of the present invention.

As shown in FIG. 2(a), a floating mechanism 2 and a fixing pin 3 are attached to a table 4 that is raised and lowered in the direction of arrow C by a lifting mechanism l installed on the underside of a conveyor line 9 such as a belt or roller. An arm 6 driven in the direction of the arrow by an arm drive mechanism 7 is mounted on the upper surface of the conveyor line 9 on which members 5 to be assembled, processed, or tested are loaded.
are arranged, and the lifting and lowering and driving are respectively controlled by a control section 8.

Furthermore, as shown in FIG. 3, the floating mechanism 2 floats the plate 20 supported by a bearing 22 fixed to the table 4 by tensioning a spring 21. is formed so that the sub-plate 23 protrudes, and the bearing 22 fixed to the sub-plate 23 comes into contact with the lower surface of the table 4 to maintain the balance of the plate 20.
0 has an attachment 2A fixed to the other surface thereof.

Therefore, when the member 5 is being transported by the conveyor line 9, the table 4 is in a lowered state and the arm 6 is not protruded, as shown in FIGS. 2(bl) and (b2).

However, when the transport of the member 5 reaches a predetermined point and the conveyor line 9 stops running, the table 4 is raised in the direction of arrow C, as shown in (C1) and (C2), and the actuator 2A 5 is lifted from the conveyor line 9, and the side wall of the member 5 is pressed by the arrow-shaped protrusion of the arm 6 so as to come into contact with the tip of the fixing pin 3, so that the member 5 can be positioned at a predetermined position.

In this case, the movement of the member 5 is carried out by the floating mechanism 2 described above.
Since the movement is performed using a soft touch, the movement is performed without any frictional movement.

〔Effect of the invention〕

As explained above, according to the present invention, fine movement due to positioning of a member can be performed by holding the member using a floating mechanism.

Therefore, movement by soft touch is possible, and since there is no frictional movement, damage to the members can be avoided, and the members can be handled directly without using a conventional pallet.

In particular, when installed in the above-mentioned clean room, the generation of dust such as metal powder can be prevented, which has a great practical effect.
