Description
Technical field:
the invention belongs to the field of electroplating, and particularly relates to a method for pad printing on a smooth surface and pad printing equipment.
The background technology is as follows:
in pad printing after electroplating or PVD, a conventional method is to use a steel gravure plate and utilize a curved pad printing head made of a silicone rubber material, dip ink on the gravure plate on the surface of the pad printing head, and press the pad printing head against the surface of a required object to print characters, patterns and the like.
Some electroplated parts, PVD parts and other metal pad printing have poor adhesion due to smooth surfaces, and customers and users have higher and higher requirements on testing, so that some tests are difficult to pass.
The invention comprises the following steps:
the invention aims to solve the technical problem of providing a method and a pad printing device for pad printing on a smooth surface, which can form concave points on the smooth surface after marking, thereby increasing friction force and better increasing adhesion after pad printing on the concave points, while not damaging the attractive appearance.
The technical proposal of the invention is to provide a method for pad printing on a smooth surface, which comprises the following specific steps,
step 1, marking the surface of an electroplated layer or a PVD layer, exposing deep layer substances through evaporation of surface layer substances, or marking marks through chemical and physical changes of the surface layer substances caused by light energy;
and 2, dipping the printing ink on the intaglio plate on the surface of the pad printing head by using the pad printing head at the position where the deep layer substance or trace is exposed, and then pad printing to form the required characters and patterns at the position where the deep layer substance or trace is exposed.
Preferably, the surface of the electroplated layer or PVD layer is marked by a laser beam for laser marking.
Preferably, the curved pad printing head made of silicone rubber material is used at the position where the deep layer substance or trace is exposed, the ink on the intaglio plate is dipped on the surface of the pad printing head, and then the pad printing head is pressed down to form characters and patterns at the position where the deep layer substance or trace is exposed.
Preferably, when marking, if re-marking is needed, the ink-coating treatment can be performed at the position marked at the previous time by the ink-coating mode, and re-marking is performed.
Preferably, in pad printing, if the pad printing is wrong or the printing is not satisfactory, the pad printing is performed again after the ink of the previous pad printing is washed by alcohol.
The invention also provides a pad printing device for the method, wherein a marking mechanism is additionally arranged at the front side of the pad printing device, and the marking structure is additionally arranged on the pad printing basis, so that beautiful patterns and fonts can be pad printed on smooth surfaces such as electroplating, PVD and the like. The pad printing mechanism and the marking mechanism of the pad printing device are all in the category of the prior art, and the pad printing device is only assembled to form the pad printing and marking integrated device.
The principle is that a laser beam is used for laser marking to mark the surface of an electroplated layer or a PVD layer permanently. The effect of marking is to expose the deep layer material by evaporation of the surface layer material or to mark the surface layer material by chemical-physical change of light energy, which roughens the surface and greatly improves the adhesion of the ink to the electroplated or PVD surface. After the trace is carved, the curved surface pad printing head made of the silicone rubber material is utilized at the trace position, the printing ink on the intaglio plate is dipped on the surface of the pad printing head, and then the carved trace is pressed down, so that characters and patterns can be attached. Therefore, beautiful characters and patterns can be printed on some smooth metal surfaces, and the test effect can be correspondingly improved.
Compared with the prior art, the invention has the following advantages:
the invention provides an integrated machine for marking and pad printing, which can meet the original performance test requirement while not damaging the beauty during pad printing on a smooth surface, can form a concave point on the smooth surface after marking, can increase friction force, and can better increase adhesive force at the concave point after pad printing.
The specific embodiment is as follows:
the invention is further described with respect to the following specific embodiments:
a pad printing method on a smooth surface comprises the following specific steps,
step 1, marking the surface of an electroplated layer or a PVD layer, exposing deep layer substances through evaporation of surface layer substances, or marking marks through chemical and physical changes of the surface layer substances caused by light energy;
and 2, dipping the printing ink on the intaglio plate on the surface of the pad printing head by using the pad printing head at the position where the deep layer substance or trace is exposed, and then pad printing to form the required characters and patterns at the position where the deep layer substance or trace is exposed.
In this embodiment, the surface of the plating layer or PVD layer is marked by a laser beam for laser marking. In actual operation, when the font size, the front, back, left and right positions and some marking parameters are to be debugged, the marking is often not one-step in place when the debugging is performed, the marking is misplaced for replacing the material, the cost is too high, the ink can be coated on the material to mark the original place again until the correct font and position are debugged, and the failure cost in the debugging process can be greatly reduced.
Preferably, the curved pad printing head made of silicone rubber material is used at the position where the deep layer substance or trace is exposed, the ink on the intaglio plate is dipped on the surface of the pad printing head, and then the pad printing head is pressed down to form characters and patterns at the position where the deep layer substance or trace is exposed. In this embodiment, a material cleaning device is added at the pad printing position: the pad printing error and poor printing exist in the production and debugging periods, the material cleaning is increased, so that the production can be continued under the condition that the production is not stopped, the production efficiency is greatly improved, and the cleaning device can adopt the sponge cleaning component and dip in alcohol for cleaning.
The invention also provides a pad printing and marking integrated machine capable of performing pad printing by adopting the method, namely, a marking mechanism is arranged on the basis of the existing pad printing device and is positioned at the front side of the pad printing device, so that the marking operation is performed on the pad printing front shell. In addition, preferably, one side of the marking mechanism is also provided with an ink applying mechanism in a matching way, and the ink applying mechanism is a sponge and a driving component thereof.
The invention provides an integrated machine for marking and pad printing, which can not only prevent the attractive appearance from being damaged during pad printing on a smooth surface, but also meet the original performance test requirement, the smooth surface can be formed into a concave point after marking, the friction force can be increased, and the adhesion can be better increased at the concave point after pad printing, so that the pad printing on the smooth surface is realized, and the pad printing effect meets the test requirement.
The foregoing is illustrative of the preferred embodiments of the present invention, and is not to be construed as limiting the claims. All equivalent flow changes made by the specification of the invention are included in the protection scope of the invention.
