JPH0489146A - Mechanism for blanking and moving sheet parts - Google Patents

Abstract

PURPOSE:To surely capture the sheet parts blanked by means of a punch and to move the parts to a prescribed position by bringing the front end of a suction moving section into contact with the sheet parts and absorbing air from the through-hole of the sheet parts, thereby sucking the sheet parts. CONSTITUTION:The front ends 7a, 7a' of the suction moving section 7 are raised by a vertical moving mechanism and the sheet parts 3' are surely captured by air suction simultaneously when the blanked sheet parts 3' are separated from the punch 2 by an air pressure. The front 7a' is rotated 180 deg. by an oscillation actuator and is further lowered and stopped. The sheet parts are then separated by the air pressure. This stop position is set as a place 8a for disposing the sheet parts of the automatic line, by which the sheet parts 3' are correctly disposed in this position. This mechanism is applicable to the automated line.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] This invention relates to a mechanism for punching and moving thin plate parts.

[Prior Art] In the manufacture of electronic devices, thin plate parts of various shapes such as circular shapes are required. For example, when soldering parts, a necessary shape is punched out from a soldering pad using a punch and then supplied to a connecting position between the parts.

Fig. 3 shows the punching mechanism and its operation for thin plate parts, and although there is no need to explain it again, the die 1 has a punching hole 1a of a predetermined shape and is supported by a suitable support 1b. . In the state of (a), when the thin plate 3 of the material is placed on the die 1 and the punch 2 is driven into it, a thin plate part 3' is punched out from the thin plate 3 as shown in (b). .

[Problems to be Solved] The punching mechanism described above is a basic one that is performed manually, and cannot be directly applied to an automated line. The reason for this is that the punched thin plate parts 3' are scattered at random locations on the support base 1b, and it is difficult to transport or move them to a predetermined position on the automated line. Note that when the thin plate component is in the form of a thin foil, it may remain attached to the tip of the punch and not be separated. Therefore, when applied to an automated line, a mechanism is required that reliably captures the punched thin plate part and moves it to a predetermined position.

The present invention has been made in view of the above, and it is an object of the present invention to provide a punching and moving mechanism for a thin plate part that reliably captures a thin plate part punched by a punch and moves it to a predetermined position.

[Means for Solving the Problems] The present invention is a mechanism for punching and moving a thin plate part such as a disk using a punch and a die, in which the punched thin plate part is separated from the punch by air pressure. Provide a through hole. In addition, it is compatible with a punch and has a tip and a through hole that contacts the thin plate part to be separated by the punch and sucks air, and has a suction movement that moves the sucked thin plate part to a predetermined position and separates it with air pressure. It is composed of several sections.

The above-mentioned suction moving part is operated by an upper moving mechanism and air pressure.
It is composed of a swing actuator that reciprocates by 80 degrees.

[Function] In the above-mentioned punching mechanism for thin plate parts, the punched thin plate parts are separated by pressurizing air into the through hole of the punch, and at the same time, the tip of the suction moving part is brought into contact with the thin plate part, and the thin plate parts are suctioned. Since the air is suctioned through the through hole of the moving part, the thin plate part is reliably caught at the tip of the suction moving part by passing this receiver. The attracted thin plate parts are moved to a predetermined position and separated by air pressure.

The tip of the above-mentioned suction moving part is raised by the vertical movement mechanism, contacts the thin plate part separated by the punch, and attracts air. The tip that has attracted the thin plate component is rotated 180 degrees by the swing actuator, further lowered, and then stopped. By setting this stop position as the placement location for the thin plate parts on the automatic line, the thin plate parts can be correctly placed at that position to configure the automated line.

Embodiment FIGS. 1(a), 1(b), and 1(c) show an overall structural diagram and a partial diagram of an embodiment in which the punching and moving mechanism for thin plate parts according to the present invention is applied to an automated line.

In Figure (a), a space 4a for the workpiece 8 of the automation line is provided on the base board 4, and an auxiliary plate 4b having a hole 4c is fixed in the space -1-. Figure (b) is a side view showing that the workpiece 8 moves in the direction of the arrow Bl. A support column 5a is erected on the auxiliary plate 4b, and the die 1 is fixed using a bracket IC. Figure (c) is a side view of the same, where the thin plate 3 such as a solder sheet is located at arrow B2 corresponding to the automation line.
Indicates movement on the dice in the direction of . Further, a guide 5b is attached to the support column 5a, a mover 5d is provided along which the guide 5b is moved upward by an air cylinder 5c, and the punch 2 is fixed to the mover 5d. The punch 2 has a through hole 2a for air Al. Next, a guide 6a is erected on the auxiliary plate 4b, a movable member 6b is provided along which the guide 6a is moved up and down by an air cylinder 6C, and the suction moving unit 7 is attached to this. A through hole 7C for air A2 is provided between the tip 7a of the suction moving part and the air port 7b, and the suction moving part is further provided with a swing actuator that reciprocates 180 degrees by air A3 from the air port 7d or 7e. It will be done.

Figure 2 is an operational diagram of the above punching mechanism, and Figure 1 (
The operation will be explained using a). In FIG. 2(A), when the punch 2 is driven into the thin plate 3 in the direction of arrow DI by the operation of the air cylinder 5C, the thin plate part 3' is punched out, and at the same time, the air cylinder 6c moves by suction. The portion 7 rises according to the arrow D2, and the tip portion 7
A comes into contact with the thin plate part, resulting in the state shown in (b). Simultaneously with the contact, air Al is press-fitted into the through hole of the punch 2 to separate the thin plate parts, and correspondingly, the air A2 is exhausted from the through hole 7C of the tip 7a, and the thin plate parts are sucked.

Next, as shown in (c), the suction moving part descends, and when air A3 is pressurized into the air bow 7b, the tip 7a rotates 180 degrees in the direction of arrow C due to the operation of the swing actuator, as shown by the dotted line. It points downward like this. When the suction moving part is further lowered to the position indicated by the arrow D2 (:), the tip end 7a fits into the hole 4c of the auxiliary plate 4b. Here air A
When the thin plate part 2 is switched to the press-fitting side and the thin plate part is separated, the thin plate part 3' or the thin plate part 3' of the work 8 is placed at the thin plate part placement position 8a. When this process is completed, the suction moving part 7 rises, and the tip rotates upward, returning to the state of (a). At the same time, the automated line operates and the workpiece 8 and thin plate 3 are moved to the next position. It is something to do.

[Effects of the Invention] As is clear from the above explanation, in the thin plate part punching and moving mechanism according to the present invention, the punched thin plate part is separated from the punch by air pressure, and at the same time, the tip of the suction moving part The thin plate part is raised by the vertical movement mechanism to securely catch the thin plate part by air suction, and then the tip part is rotated by 180 degrees by the swinging actuator, and then stopped and lowered to be separated by air pressure. By using this stop position as the place where the thin plate parts are placed on the automatic line, the thin plate parts can be correctly placed at that position, which is highly effective in providing a punching movement mechanism that can be applied to the automated line.
