Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to a device for conveying, with high precision, strip-shaped metal plates connected to short thin plates, which are used in large quantities as components of electronic devices, etc. It is.

(b) Background of the technology Recent electronic devices are becoming increasingly smaller and more precise, and for example, short thin products such as the magnetic head arm and gimbal components of magnetic disk devices are required to be extremely thin, small, and highly precise products. It is becoming more and more common. However, if short thin sheets with high precision and complex shapes are conveyed while being held between rollers or placed carelessly in a hopper, etc., problems such as scratches and distortions may occur due to contact and mutual interference during conveyance. Furthermore, it is extremely undesirable from the viewpoint of quality, work efficiency, and safety for operators to handle the short thin sheets each time they are processed. For this reason, there is a strong demand for the development of a belt-shaped metal sheet conveying device that can safely and reliably convey the short thin sheet products through the processing steps.

(c) Prior art and problems Figure 1 is a diagram for explaining the conventional method of handling and transporting short thin sheets. In the figure, 1 indicates the short thin sheets, 2 the hopper, and 3 the tweezers. ing.

As shown in FIG. 1, this is a method in which an operator manually picks up a short thin sheet product 1 housed in a hopper 2 with tweezers 3 and transports it to a predetermined process. However, this method inevitably causes flaws and deformations due to mutual interference between the short thin sheets 1 in the hopper 2 and external forces applied during manual operation, and is also extremely inefficient.

(d) Purpose of the invention In view of the above-mentioned drawbacks of the conventional technology, the present invention has been developed by connecting a plurality of short thin plates to a belt-shaped connecting part of a predetermined length at one end in a comb-tooth shape to form a workpiece belt-shaped metal plate. The object of the present invention is to provide a belt-shaped metal plate conveying device that can convey a belt-shaped metal plate efficiently and with high precision without damaging the part to be processed (a short thin sheet product) by gently holding and conveying the metal plate.

(e) Structure of the invention According to the invention, the object is to connect a plurality of workpiece parts to a belt-like connecting part of a predetermined length in a comb-like shape at a predetermined interval at one end of the workpiece parts, A belt-shaped metal plate to be processed, which has a transport hole in the belt-shaped connecting part and a positioning hole for a positioning pin on the processing mold in the processed part, is transported on a transport track with respect to the processing mold. The positioning device includes a conveyance table that is conveyed by a feeding device on the conveyance track, and is provided to be movable up and down on a slide shaft via a spring force on the conveyance table, and conveys the belt-shaped connecting portion. a holder having a clamping surface with a holding pin that loosely fits into the hole; The metal plate is held, and while the metal plate is being transported by the conveyor table, the held state of the strip metal plate to be processed is pushed up by the spring force, and positioned higher than the processing surface of the processing die, and then moved to a predetermined processing position. A belt-shaped metal plate is transported, characterized in that the positioning pin on the processing die and the positioning pin of the processed part are engaged with each other by being pushed down against the spring force at a stop position corresponding to the above-mentioned. This is accomplished by providing a device.

In these figures, 1A to 1N are parts to be processed that are separated into short thin sheets after multiple processes, 5 is a conveyor table, 6 is a slide shaft, 7 is a holder, 7' is a pressing zone, 8 is a presser plate, 9 is a return spring, 10 is a loose fitting step, 11 is a connecting portion, 12 is a conveyance hole, 13 is a positioning hole, 14 is a band-shaped metal plate, 15 is a conveyance track, 16
17 is a transport pin, 17 is a transport pin insertion hole, 18 is a transport control mechanism, 20 is a holding pin, 21 is a mold, and 22 is a positioning pin.

As shown in FIG. 2, it slides in the vertical direction along a pair of slide shafts 6 provided on the conveyance table 5, and the other end of the slide shafts 6 is moved by a return spring 9 attached to the conveyance table 5. A plurality of workpieces 1A to 1N are connected to a predetermined length between a holder 7 that is pressed against a presser plate 8 fixed to the holder 7 to maintain a predetermined height, and a loose fitting step 10 provided on the presser plate 8. A band-shaped metal plate 14 connected in a comb-like manner while maintaining a predetermined direction and interval and provided with a conveying hole 12 and a positioning hole 13 is inserted into the portion 11.
When the holder 7 is pushed down in the direction of arrow A and the carrying hole 12 provided in the band-shaped metal plate 14 is loosely fitted into the holding pin 20 attached to the holder 7, the holder 7 is returned to its original position. Band-shaped metal plate 14
is held in a loosely fitted state by the holder 7 and the loosely fitting step 10 provided on the presser plate 8.

The conveyance platform 5 holding the band-shaped metal plate 14 in a loosely fitted state in this way is
Mold 2 attached to a press machine that performs predetermined processing on
1, the conveyor pin 16 moves and stops in the direction of arrow B under the control of the conveyance control mechanism 18, and the conveyor pin insertion hole 17 is inserted into the conveyor pin insertion hole 17. be done. Therefore, the processed parts 1A to 1N are sequentially transported to the next process or stopped on the mold 21 for processing. As shown in FIG. 3a, the processed parts 1A to 1N are transferred to the mold 2
1, and when the holder 7 is stopped for processing, a plunger (not shown) drawn out from a press device presses a pressing zone 7' of the holder 7, and the holder 7 is moved in the direction of arrow A. pushed down in the direction. And the to-be-processed parts 1A to 1
N moves in the direction of arrow C as shown in FIG. 3b and comes into close contact with the mold 21. At this time, the positioning pins 22 provided in the mold 21 engage with the positioning holes 13 provided in the processed parts 1A to 1N, so that the positions of the processed parts 1A to 1N are held with high precision. It has a structure that allows
