Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrolytic marking apparatus for engraving characters, figures and the like on the surface of a metal using an electrode and an electrolytic solution.

[0002]

2. Description of the Related Art As a device for imprinting characters, figures, and the like on a metal surface, electrodes are arranged on the metal side to be imprinted and on the side on which an electrolyte is held and imprinted. Various devices have been proposed for electrolytic engraving with a stencil in which characters, figures, etc. are cut out between them (for example, Japanese Utility Model Publication No. 50-3).
No. 5051, Japanese Utility Model No. 6-42172, Japanese Utility Model No. 6-455, etc.).

[0003] The stencils used in these apparatuses usually use stencils produced by silk-screen printing at the request of specialists, and these stencils are repeatedly used as a master for engraving. Things.

Also, as a material of the stencil, a pattern paper or a template has been used in the past, but at present, a polychlorinated resin material or a plastic resin material is used to improve durability. Since a stencil of this type is repeatedly used as an original for engraving, a sheet material having a certain degree of rigidity and capable of being attached to the tip of a marking head is used.

[0005]

However, these conventional electrolytic marking devices are generally large-sized devices provided with a rectifier, a transformer, and the like, and there is an inconvenience in carrying these devices. Therefore, for any product,
It is common to carry to the place where the electrolytic marking device is installed, and it was impossible to carry this electrolytic marking device.

In addition, since a stencil is handed over to a printing company to manufacture a stencil and the stencil is manufactured based on the stencil, the operation of performing electrolytic marking starts with the manufacture of the stencil. . Therefore,
In the past, many days were required to make this stencil, and at the same time high manufacturing costs were incurred.
This stencil manufacturing operation has the disadvantage of reducing the efficiency of the entire electrolytic marking operation and increasing the marking cost.

Conventionally, the stencil has a certain degree of rigidity in order to increase the durability of the stencil. For this reason, when marking is performed on a curved surface, it has been difficult to bring a rigid stencil into close contact with the curved surface.

Further, since one stencil is repeatedly used, when engraving a large number of products, the stencil is usually mounted on the marking head to facilitate continuous engraving. However, depending on the product, it is necessary to set the stencil not on the marking head but on the product. For example, this is the case when a small product or the marking surface is a curved surface. A stencil is set on the marking surface, and the marking head is pressed against the stencil in this state. As described above, when stencils are set on individual products, a plurality of stencils are provided and attached to each product, so that the marking head can be continuously operated.

However, since the production cost of the stencil is high, preparing a plurality of stencils with the same engraving is not realistic because the cost increases the marking cost. Therefore, when engraving individual products using one stencil, the work of setting the stencil on one product and then pressing the marking head is repeated as many times as the number of products. In the case of continuous repetition, it has required an extremely large amount of work.

Accordingly, the present invention has been made to solve the above-mentioned problems, and enables the carrying of an electrolytic marking device, and enables highly accurate marking even when the marking surface is a curved surface. An object of the present invention is to provide an electrolytic marking apparatus that can perform a continuous engraving operation rationally by easily and inexpensively manufacturing a stencil for electrolytic marking.

[0011]

In order to solve the above-mentioned problems, a first means of the present invention is to dispose electrodes on a metal engraved object P and a marking head 1 to which an electrolytic solution is attached, respectively. In an electrolytic marking apparatus for engraving by energizing the engraved object P via the stencil 3 between the engraved object P and the marking head 1, an electrode clip 2 for connecting one electrode to the engraved object P; In other words, a pen-shaped marking head 1 that rubs along the engraved shape of the stencil 3 superimposed on the engraved object P is provided.

In the marking head 1 of the second means, a water retaining body 1B for attaching an electrolytic solution is provided at the tip of a pen-shaped holder 1A, and a pilot lamp 1C which emits light when energizing and engraved is provided on the holder 1A. It is provided.

The electrode clip 2 of the third means is connected to a metal plate 4 on which a small object P is placed, and a portable battery 5 containing a battery 5 for energizing the electrode clip 2 and the marking head 1 is stored. The metal plate 4
And the marking head 1 are mounted.

The stencil 3 of the fourth means is used to
A tape formed of a polyester film 3A arranged on the side and a hydrophilic coating material 3B arranged on the marking head 1 side of the polyester film 3A,
The means for solving the problem is that an arbitrary engraved pattern is formed in the surface of the stencil 3 sequentially from the end by the printer device Q having a thermal transfer head.

[0015]

Embodiments of the present invention will be described below with reference to the drawings.

In the apparatus according to the present invention, electrodes are arranged on a metal engraved object P and a marking head 1 to which an electrolytic solution is adhered, respectively, and a stencil 3 interposed between the engraved object P and the marking head 1 is provided. This is an electrolytic marking device that performs engraving by energizing the object P from above.

The power supply used in the device of the present invention is 6V to 1V.
An electrode clip 2 which uses a battery 5 of about 2 V and connects one of the electrodes to the object P is provided. The other electrode is connected to a pen-shaped marking head 1 and rubs the marking head 1 along the engraved pattern of the stencil 3 superimposed on the engraved object P.

The marking head 1 is formed of a pen-shaped holder 1A, and is provided with a water retaining body 1B at the tip of the holder 1A to which an electrolytic solution is attached. Then, after the electrolytic solution is attached to the water retaining body 1B, it contacts the surface of the stencil 3. The material of the water retaining body 1B is preferably a water-absorbing material such as sponge or cotton. In addition, the pilot lamp 1C is mounted on the holder body 1A opposite to the water retaining body 1B, and the pilot lamp 1C emits light at the time of engraving the energization, so that energization can be confirmed during work.

The illustrated electrode clip 2 is connected to a metal plate 4 on which a small object P is placed (FIG. 1).
reference). The metal plate 4 is used, for example, when the object P is extremely small or when engraving is performed on the object P having a shape in which the electrode clip 2 cannot be fixed. Therefore, when the electrode clip 2 can be directly fixed to the engraved object P, engraving can be performed basically without using the metal plate 4.

Marking head 1 and electrode clip 2
Is mounted in a portable storage body 6 together with the battery 5 (see FIG. 1). In the illustrated example, the battery 5 is housed inside the housing 6 (see FIG. 3). Also, on the surface of the storage body 6,
A support hole 6A for inserting the marking head 1 and a container 6B for storing the electrolyte are provided (see FIG. 1). Further, the metal plate 4 is detachably attached to the housing 6 via the binder 6C. Place the electrode clip 2 on the object P
When the metal plate 4 is not energized by being connected to this, the metal plate 4 can be used as a work table.

The stencil 3 comprises a polyester film 3A disposed on the side of the object P to be engraved and a hydrophilic coating material 3B disposed on the side of the marking head 1 of the polyester film 3A. The stencil 3 has a tape shape, and has a printer device Q having a head for thermal transfer.
Then, an arbitrary engraved pattern is formed in the surface of the stencil 3 in order from the end. The stencil 3 of the present invention is formed by winding the stencil into a tape shape that can be wound around.

The polyester film 3A disposed on the side of the engraved object P of the stencil 3 is tough and has excellent insulation properties, and is easy to fit into the surface of the engraved object P when it is mounted, and the surface of the engraved object P has a curved surface. However, there is an advantage that it can be easily brought into close contact. On the other hand, the hydrophilic coating material 3B arranged on the marking head 1 side of the stencil 3
Use ultra-thin Japanese paper. This Japanese paper, when brought into contact with the water retaining body 1B to which the electrolytic solution has been attached, makes the electrolytic solution a stencil 3
The stencil 3 can be easily wound around the surface of the stencil 3 by adhering it thinner than at least the polyester film 3A.

The present invention starts by mounting a tape-shaped stencil 3 on a printer T having a thermal transfer head to form an engraved image (see FIG. 4). At this time, the stencil 3 can be easily mounted by storing the stencil 3 in a cassette-shaped tape holder and mounting the tape holder on the printer device Q having a thermal transfer head. Further, as the printer device Q having a head for thermal transfer, a printer connected to a personal computer, a label printer that forms arbitrary characters or the like on a tape-shaped label, or the like can be used as the printer device Q. In this case, the supporting tape R for supporting the stencil 3 is arranged on the polyester film 3A side of the stencil tape 3 and wound around the stencil 3 and stored in a cassette case-shaped tape holder, so that the tape-shaped stencil 3 can be smoothly placed. It is possible to pull out. In addition, the head can be protected as a heat transfer body when forming the engraved shape (see FIG. 4).

As described above, an arbitrary engraved pattern is formed by punching sequentially from the end of the stencil 3 by the printer device Q. In a printer or a label printer connected to a personal computer, the same engraved shape can be formed arbitrarily and repeatedly. Therefore, when there are a plurality of engraved objects P, a plurality of stencils 3 having the same engraved shape are formed in accordance with the number of engraved objects P. It may be cut out (not shown).

Then, the cut side of the stencil 3 is brought into close contact with the polyester film 3A side along the surface shape of the stamp P. At this time, when the electrolytic solution is attached to the polyester film 3A, the stencil 3 adheres due to the surface tension even if the surface of the object P has a curved surface. Therefore, when the same engraving pattern is formed on a plurality of engraved objects P, the electrolytic solution can be attached to each stencil 3 and can be kept in close contact with the engraved objects P.

Finally, the coating material 3B of the stencil 3 fixed to the object to be stamped P as described above is brought into contact with the water retaining body 1B having the electrolytic solution applied thereto while tracing therethrough, thereby energizing the object to be stamped P to form an engraved shape. Things.
