Abstract

PURPOSE:To enable thin sheet parts to be separated one by one to convey them in a given spot, by a method wherein the thin sheet part can be vacuum- adsorbed to a separating taking-out part and a conveying hand. CONSTITUTION:Thin sheet parts 1 are adsorbed one by one to an adsorbing recessed part 6, having an adsorbing surface 6A conforming to the upper surface shape of the thin sheet part 1, by providing sucking holes in the adsorbing surface 6A. By forming sucking holes 14 in an adsorbing surface 12A of an adsorbing projection 12 having the adsorbing surface 12A conforming to the under surface shape of the thin sheet part 1, the thin sheet part 1, adsorbed and held to a separating and taking-out part 3 can be easily conveyed to a conveying hand 10. This enables the thin sheet parts 1 in a laminated state to be separated one by one to convey then to a desired assembling position.

Description

[Detailed Description of the Invention] [Summary] When carrying small thin plate parts such as washers and terminal pieces to be fastened with small screws to an assembly location, the stacked thin plate parts are separated into one piece by vacuum suction means. It can be taken out in the same state and automatically supplied.

[Industrial application field]

The present invention relates to a method for individually supplying small sheet metal parts in the form of washers.

Washer-shaped thin plate parts, such as washers, are used for electronic devices.

Terminal pieces etc. are widely used.

There is a strong demand for automation of assembly work for thin plate parts that are small and difficult to assemble by hand.

[Conventional technology]

Conventionally, vibration feeding methods have been widely used as means for individually feeding small parts such as washers, pads, machine screws, etc. to assembly locations.

The vibration supply method is an individual supply method as described below.

When equipment is used that has a circular container into which a large amount of small parts are put, and a guide groove connected tangentially to the outer circumference of the container and whose end is inclined downward, the container is vibrated, and the small parts are moved into the container due to the vibration. The guide grooves are fed into the guide groove while being aligned in a single line.

The small component fed into the guide groove moves down the guide groove to the end of the guide groove due to its own weight and vibration.

Therefore, by grasping the guide groove end with a robot hand, etc., the small parts can be taken out and
M can be aligned to a desired location.

[Problem that the invention seeks to solve]

However, when trying to feed small thin plate parts to a desired location using the conventional individual feeding method described above, it is often the case that two sheets are fed into the guide groove in a stacked state. Therefore, there is a problem in that it is difficult to separate and grasp the thin plate parts one by one with a robot hand or the like when the two thin plate parts are fed in a stacked state.

[Means for solving problems]

In order to solve the above-mentioned conventional problems, as shown in FIG. A separating and extracting part 3 is formed with a suction recess 6 and is driven in the vertical direction facing the thin plate part 1, and a separating and extracting part 3 that protrudes horizontally from the tip of a hand body 11 that is horizontally and rotationally driven as desired. - The transfer hand 10 has a suction protrusion 12 that is laterally inserted into the suction recess 6 in a dead center state.

Then, the separating and extracting section 3 is lowered, and the upper surface of the thin plate component 1 is brought into close contact with the suction surface 68, which is the lower surface of the suction recess 6, and one of the uppermost parts of the stacked thin plate components 1 is taken out by vacuum suction and separated. After the part 3 is raised, the suction surface 128 is inserted into the lower surface of the thin plate component 1 that has been suctioned so that the suction surface 12A, which is the upper surface of the suction protrusion 12, comes into close contact with the lower surface of the thin plate component 1 that has been suctioned.

After that, the thin plate part 1 is vacuum-adsorbed and removed from the separation section 3.
Transfer to the transfer hand 10. Next, the transfer hand 10 is driven to feed the thin plate part 1 to a desired position.

[Effect]

According to the means of the present invention, only one thin plate component 1 can be sucked by providing a suction hole in the suction surface 6A of the suction recess 6 having the suction surface 68 that matches the top surface shape of the thin plate component 1. I can do it.

In addition, by providing a suction hole in the suction surface 128 of the suction protrusion 12, which has a suction surface 12^ that matches the shape of the lower surface of the thin plate component 1, the thin plate component 1 held by suction in the separation/removal section 3 is
can be easily transferred to the transfer hand 10.

Therefore, the laminated thin plate parts 1 can be separated one by one and transported to a desired assembly position.

al, (b), (cl) are side views showing the subsequent steps of the individual supply method of the present invention, respectively.

In FIGS. 1 to 3, a thin plate component 1, which is a spring washer made by punching out a thin steel plate into a curved circle, for example, has a center hole 1a at its axis through which a machine screw loosely passes.

The individual supply device of the present invention is composed of a mandrel 2 for stacking and storing thin plate parts 1, a separation/take-out section 3, and a transfer hand 10.

A large number of thin plate parts 1 are stacked on a mandrel 2 which is vertically fixed to a base and is fitted into a center hole 1a.

The separation and extraction section 3 mounted above the mandrel 2 is configured to be able to be driven reciprocally in the vertical direction by a drive mechanism (for example, an air cylinder) not shown. It is a provision. A curved suction surface 6</b>A having the same curved shape as the top surface of the thin plate component 1 is formed on the upper bottom surface of the suction recess 6 .

Further, the take-out main body 4 is provided with a cut hole 5 which is open on one side so as to extend vertically through the suction recess 6 (11Tl) to provide relief for the mandrel 2.

In addition, suction holes 7 are provided in each of the parts divided by the cut holes 5 in the extraction main body 4, and the ends thereof are opened to the suction surface 6, respectively, and a suction pipe 8 is provided at the other end of the suction hole 7. A vacuum pump (not shown) is provided to expel air from the gap formed between the negative surface of the thin plate part 1 and the suction surface (the lower surface of the trough).

When the separating and extracting section 3 is at the top dead center, the transfer hand 10 having the suction protrusion 12 facing the suction recess 6 is rotated in a horizontal plane by a drive mechanism (not shown), and is connected to the extracting main body 4. It is configured to reciprocate between the assembly points of the thin plate part 1. Further, the hand main body 11 is provided with an air cylinder 16, and the suction protrusion 12 is horizontally driven so that the suction protrusion 12 can be inserted into and removed from the suction recess 6 from the horizontal direction.

On the upper surface of the suction protrusion 12, a curved suction surface 12A having the same curved shape as the lower surface of the thin plate component 1 is formed.

Further, the suction protrusion 12 is provided with a notch hole 13 in which the end faces of the six suction recesses are open so as to vertically pass through the suction protrusion 12, thereby providing relief for the mandrel 2.
