Description

[Detailed Description of the Invention] [Summary] An engraving machine and a robot are connected, and a control device storing a character table and a control program controls the robot and the engraving machine to engrave characters on a workpiece.

[Industrial application field]

The present invention relates to robot-based automation of an engraving machine that traces characters on a matrix with a contact and engraves the characters at a predetermined magnification.

Traditionally, in the production of molds for mold processing such as casting and plastic molding, and in the processing of nameplates, etc., a method has been adopted in which the workpiece is cut by tracing the mother mold with a contact and operating a cutter. There is.

Since such a method requires manual operation of the contacts, it requires skill and man-hours, and there is a demand for labor savings.

[Conventional technology]

FIG. 3 is a perspective view showing the outline of the engraving machine.

As shown in the figure, the engraving machine includes a table 1 on which a workpiece 7 is mounted, a rotary shaft 3 that faces the table 1 and rotates with a cutter 2 at its tip, and a contactor ( It consists of a pantograph 5 that reduces or enlarges the operation of Stylus 4 at a desired magnification and transmits it to a cutter 2 attached to a rotating shaft 3, and a copy table 6 equipped with a dial engraved with characters that serve as a matrix. There is.

For engraving, the workpiece 7 is fixed to the table 1, and then the dial is fixed to the copy table 6.

After that, the cutter 2 is rotated and the workpiece 7 is manually carved until it reaches a predetermined depth.

When a predetermined depth is reached, trace the letters on the dial plate with the contact 4.

Then, the operation is performed by the cutter 2 depending on the pantograph 5.
The desired characters are engraved onto the workpiece 7 at the desired magnification.

[Problem to be solved by the invention 3 Characters are engraved on the workpiece as described above, but the engraving is done using a so-called copying method in which the characters (matrix) on the dial board are traced with a contact and the cutter is operated. is taken.

This method requires manual operation of the contacts and is not suitable for mass production. On the other hand, it requires a large amount of man-hours and P-mixing, making the product expensive.

[Failure to solve the problem]

FIG. 1 is a perspective view showing an automated method of engraving according to the present invention.

In the present invention, there is provided a control device that stores a control program 12 for controlling the engraving machine 8 and the robot 11, a character table 9 containing character information, and an engraved character memo 1/0 in which engraved characters are stored. 13 is provided, and the robot 11 is used to attach and detach the workpiece 7 to and from the table 1, and to control the cutter 2 via the pantograph 5 and the rotating shaft 3.

[Effect]

By configuring as described above, a dial plate becomes unnecessary, and engraving work can be performed continuously without manual intervention.

〔Example〕

FIGS. 1 and 2 show an embodiment of the present invention, with FIG. 1 being a perspective view showing the automated engraving system of the present invention, and FIG. 2 being a block diagram of the automated engraving system.

In the figure, 9 is a character table, 10 is an engraving character memory, 11 is a robot, 12 is a control program, 13 is a control device, 14 is a robot control section, 15 is an engraving machine control section, 16 is a keyboard, and 17 is a 18 is an arm, 19 is a suction pad, 20 is a pilot pin, 21 is a stand, and 22 is an abutment.

Identical parts are designated by the same reference numerals throughout the figures.

As shown in FIG. 2, the engraving automation system of the present invention includes a control program 12 that controls the engraving machine 8 and the robot 11;
The robot 11 is equipped with a character table 9 containing information such as character position data (coordinates), and a control device 13 that stores a memo 1 month 0 in which the engraved characters are stored.
4, the engraving machine 8 is controlled via an engraving machine control section 15.

Also connected to the control device 13 are a keyboard 16 that outputs character codes and a display 17 that displays engraved characters and the like.

The engraving operation will be explained step by step below.

The robot 11 is equipped with a suction pad 19 and a pilot pin 20 at the tip of the arm 18, as shown in FIG.

robot) 11 is a control device 1 based on a control program 12.
In response to the command No. 3, the suction pad 19 is brought into contact with the workpiece 7 placed on the stand 21 via the robot control unit 14, and the workpiece 7 is suctioned by vacuum.

The attracted workpiece 7 is carried to the table 1 of the engraving@8 and fixed at a predetermined position by the abutment 22 or the like.

After fixing the workpiece 7, the robot 11 moves and inserts the pilot pin 20 into the hole in the pantograph 5 in which the slider 4 is to be attached.

When the above-mentioned operations are completed, the keyboard 16 shown in FIG.

The control device 13 temporarily stores the input character information in the engraved character memory 10.

Information such as characters to be engraved is displayed on the display 17, and the operator can confirm whether the engraving is correct or incorrect.

When more manpower is finished, will it be controlled? The IO device 13 issues a command to the engraving machine control section 15 according to the control program 12 to rotate the cutter 2 and move the cutter 2 downward into the workpiece 7 until it reaches a predetermined engraving depth.

This movement can be easily performed using, for example, an air cylinder attached to the rotating shaft 3'.

When the cutter 2 reaches a predetermined depth, the control device 13 reads the engraved character from the engraved character memory 10 and reads the coordinate data of the corresponding character from the character table 9.

Then, the robot controller 14 is instructed to drive the arm 18, and the cutter 2 is moved via the pilot pin 20 and pantograph 5 to engrave desired characters.

When engraving is completed, the cutter 2 is raised and rotation is stopped.

Then, the robot 11 removes the pilot pin 20 from the pantograph 5, attaches the suction pad 19 to the workpiece 7 on the table 1, and returns it to the stand 21.

As described above, 1.
The characters marked a are automatically engraved.

For this reason, mass production is possible, and unmanned work can be realized.

Note that since the characters are drawn by the robot 11, the accuracy is improved compared to when the dial is manually traced with the slider 4.

〔Effect of the invention〕

As explained above, by applying the engraving automation method of the present invention to engraving work, unmanned engraving can be realized and mass production can be handled, which has great industrial and economical effects.
