Description

Laser etching production line on chromium and technological method thereof

Technical Field

The invention relates to the technical field of laser etching, in particular to a laser etching production line on chromium and a process method thereof.

Background

For the working principle of laser coloring, there are two different views at home and abroad. One of them is the oxide film viewpoint: the laser can enable the metal surface to present color because the laser pulse is used as a local heat source, the metal surface is subjected to oxidation reaction in the irradiation process, and a layer of transparent or semitransparent oxidation film is formed on the metal surface; the oxide film generates interference effect under white light, so that the oxide films with different thicknesses generate different colors. This theoretical view is in agreement with the theory of color formation of oxide films which is believed by the traditional metal coloring method. Based on the theory, the principle of laser etching in the prior art is as follows: forming an oxide film on the surface of the metal in the process of irradiating the metal by laser; and the oxide films with different thicknesses correspondingly generate different colors.

In the existing laser etching technology, the laser color development process is mainly applied to pure metal with larger thickness (more than millimeter), such as metal pieces, such as iron pieces, stainless steel pieces and the like. The metal material can bear higher temperature radiated by laser, and the material of the metal piece of the type can not be obviously influenced after laser etching processing, such as breakdown, thermal deformation and the like.

However, a plastic workpiece has poor heat resistance and is easily deformed at high temperatures. In order to realize laser etching on a plastic part, in the prior art, a metal coating is generally plated on the surface of the plastic part, and then laser etching is performed on the metal coating. However, in the conventional laser etching technology, when a workpiece with a plastic part as a base material and a metal coating as a surface layer is subjected to laser etching, the problem that the metal coating bubbles (i.e. the metal coating is separated from the plastic base material) or the plastic base material is deformed when the workpiece is subjected to high temperature is inevitable.

Of course, in the prior art, the laser etching process of electroplating and pad printing also exists, but the process of electroplating and pad printing has the problem of poor binding force.

The working process of the chrome laser etching production line 10 is as follows (please refer to fig. 1, 2 and 3):

firstly, the feeding device 20 conveys the plastic workpiece to a designated position; then the feeding mechanical arm 30 grabs the plastic workpiece on the feeding device 20 onto the laser etching bearing plate 420; the laser etching machine head 430 performs laser etching on chromium on the plastic workpiece on the laser etching bearing plate 420; the blanking mechanical arm 50 grabs the plastic workpiece subjected to the chrome upper laser engraving to the blanking device 60; the blanking device 60 carries out transmission blanking on the plastic workpiece;

it should be noted that, in the process of performing the chrome-on-chrome laser etching on the plastic workpiece by the laser etching head 430, the transverse translation motor 442 drives the transverse translation screw 443 to indirectly drive the laser etching head 430 to reciprocate along the horizontal and transverse directions; correspondingly, the longitudinal translation motor 452 drives the longitudinal translation screw 453 to indirectly drive the laser etching bearing plate 420 to reciprocate along the horizontal longitudinal direction; therefore, the plastic workpiece on the laser etching bearing plate 420 and the laser etching head 430 move relatively in the horizontal direction, so that the laser etching head 430 realizes laser etching on a plane on the plastic workpiece;

according to the laser etching production line 10 on chromium, the plastic workpiece which takes plastic as a base material and has a surface metal chromium layer with the thickness of only 30-70 microns is subjected to laser etching processing, the plastic workpiece cannot deform, the plastic base material cannot be separated from the metal chromium layer, the chromium layer is slightly etched by the laser etching, and the original performance of the plastic workpiece is kept to the maximum extent;

the upper chromium laser etching production line 10 of the invention has the following upper chromium laser etching parameters for plastic workpieces:

the laser power, the scanning speed, the pulse frequency, the filling space and the filling pattern are basic parameters, and the beam spot change and the imprinting times are key parameters influencing the color change under the basic parameters; each 1 value of beam spot change represents that the laser focal length deviates 0.1 mm;

it should be further noted that laser etching is a high-precision processing procedure, so that the requirements on the working environment are strict, and the requirements on the precision of the position, the angle and the like of a plastic workpiece are also high; however, during the process of transporting and processing the plastic workpiece, the plastic workpiece itself is inevitably stained with dust, excess materials and the like, and the dust and excess materials stained on the plastic workpiece are transferred and adhered to the conveyor belt 200 during the process of contacting with the conveyor belt 200; moreover, dust in the processing environment may also fall and adhere to the conveyor belt 200; dust, excess materials and the like adhered to the conveying belt 200 can directly influence the placing angle and position of the plastic workpiece, so that the laser etching precision on the chromium of the plastic workpiece is influenced, and the defective rate of the laser etching of the plastic workpiece is increased; moreover, dust, excess materials and the like adhered to the conveyor belt 200 can also affect the conveying smoothness of the conveyor belt, so that the conveying accuracy of the plastic workpieces is further affected;

in order to ensure the accuracy of the position and the angle of the plastic workpiece, the laser etching production line 10 on chromium is provided with a synchronous cleaning mechanism 300 respectively arranged on a feeding device 20 and a discharging device 60; the synchronous cleaning mechanism 300 is used for cleaning the conveyor belt 200, so that the conveyor belt 200 is kept in a clean state, the conveyor belt is ensured to convey plastic workpieces stably and accurately, and the reject ratio of the plastic workpieces is reduced;

the operation of the synchronous cleaning mechanism 300 will be further described (please refer to fig. 4 to 11):

when the feeding device 20 conveys the plastic workpiece, the conveying motor 400 drives the conveyor belt 200 to continuously run; in the operation process of the conveyor belt 200, as the annular contact transmission surface 334 of the transmission roller 330 is in contact with the conveyor belt 200, friction force is generated between the conveyor belt 200 and the annular contact transmission surface 334, so as to drive the transmission roller 330 to rotate; the transmission roller 330 drives the transmission cord 340 to move continuously in the transmission process, and the transmission cord 340 drives the driven turntable 322 to rotate continuously in the continuous movement process; the driven turntable 322 further drives the transmission connecting column 323 to do circular motion by taking the central shaft of the driven turntable 322 as the center; in the process of circular motion of the transmission connecting column 323, the transmission connecting piece 324 and the sponge wiper 325 do circular motion along with the transmission connecting column 323; when the sponge wiper 325 indirectly follows the transmission connecting column 323 to do circular motion, the conveyor belt 200 is continuously wiped, so that dust, excess materials and the like adhered to the conveyor belt 200 are wiped cleanly;

it should be particularly noted that the wiping of the belt 200 by the sponge wiper 325 is not a reciprocating wiping in a single direction (a single transverse direction or a single longitudinal direction), but a reciprocating wiping in a circular motion, and the cleaning effect of the circular motion wiping track is remarkably improved compared with that of the wiping in the single direction;

it should be noted that, in the present invention, the synchronous cleaning mechanism 300 is provided without separately providing a power source, and directly obtains power from the conveyor belt 200; by adopting the design, on one hand, the structure of the laser etching production line 10 on the chromium is simpler, the energy utilization rate is high, and the equipment cost is low; on the other hand, the operation of the synchronous cleaning mechanism 300 is synchronous with the operation of the feeding device 20, so that the conveyor belt 200 is kept clean and clean all the time in the operation process, the waste of energy is avoided, and the operation and the control are simple;

it should be further noted that the transmission wire 340 is always in a tensioned state during the working process, but the transmission wire 340 may be loosened when being in the tensioned state for a long time; in order to ensure that the synchronous cleaning mechanism 300 can stably and reliably obtain a power source from the conveyor belt 200 for a long time and normally operate, the synchronous cleaning mechanism 300 is further provided with a tensioning adjusting column 350; the tension degree of the transmission wire rope 340 is adjusted by adjusting the tension adjusting column 350, so that the synchronous cleaning mechanism 300 can be ensured to keep stable operation for a long time; of course, when the transmission wire 340 is loosened, the normal operation of the synchronous cleaning mechanism 300 can be ensured by replacing the transmission wire 340; however, when the transmission wire 340 needs to be replaced, the transmission wire 340 needs to be removed and then a new transmission wire 340 needs to be installed again, and the process needs to be performed on deep disassembly and assembly of the synchronous cleaning mechanism 300, so that the work load is large, and the time consumption is long; and frequent replacement of the new drive line cord 340 results in high maintenance costs for the device; the tensioning degree of the transmission wire rope 340 can be adjusted only by adjusting the tensioning adjusting column 350, and the design avoids frequent deep disassembly of the synchronous cleaning mechanism 300, so that the maintenance is simple and time-saving, and the cost of maintenance materials is low;

it should be noted that, on one hand, the annular avoiding groove 331 and the annular contact transmission surface 334 are designed to accommodate the transmission cord 340 through the annular avoiding groove 331, so as to prevent the transmission cord 340 from protruding out of the annular contact transmission surface 334 and directly contacting the transmission belt 200, thereby ensuring that the annular contact transmission surface 334 is always kept tightly contacting the transmission belt and enabling the transmission belt to drive the transmission roller 330 to rotate; on the other hand, the transmission wire rope 340 is accurately and stably limited, so that the transmission roller 330 is prevented from deflecting and dislocating in the operation process, and the stability of the synchronous cleaning mechanism 300 is ensured;

it should be further noted that the guide block 360 disposed in the synchronous cleaning mechanism 300 guides the transmission cord 340, so as to ensure that the transmission cord 340 keeps smooth and stable rotation, and the phenomenon of jamming or derailing does not occur;

it should be further noted that the lifting assembly 370 provided in the synchronous cleaning mechanism 300 lowers the cleaning base 310 when the sponge wiper 325 is replaced and the tension adjusting column 350 is adjusted, so as to facilitate the work of replacing the sponge wiper 325 and adjusting the tension adjusting column 350, and thus the replacement of the sponge wiper 325 and the adjustment of the tension adjusting column 350 are time-saving and efficient.

As shown in fig. 12, in the present invention, the transmission connection column 323 is disposed at the eccentric position of the driven turntable 322, and the transmission connection member 324 is inserted into the transmission connection column 323 through the through hole 326, so that, during the rotation of the driven turntable 322, the driven turntable 322 drives the transmission connection member 324 to perform a swinging rotation through the transmission connection column 323 at the eccentric position, and the transmission connection member 324 further drives the sponge wiper 325 thereon to wipe the conveyor belt 200 in a swinging rotation manner. During the process of wiping the conveyor belt 200 by the sponge eraser 325 in a manner of swinging, the sponge eraser 325 will move towards both sides of the conveyor belt 200 (as shown by the straight line arrows in fig. 12, the arrows indicated by the numbers 1, 2, 3, and 4 continuously represent that the sponge eraser 325 forms a complete swinging type rotating motion), so that part of the dust, the excess materials, and the like on the conveyor belt 200 will be pushed to both sides by the sponge eraser 325 and will fall off. Compared with the sponge wiper 325 which makes a single reciprocating movement along the conveying direction of the conveyor belt 200, the sponge wiper 325 wipes the conveyor belt 200 in a manner of swinging rotation, and the cleaning effect is better.

The invention also discloses a laser etching process method on the chromium, which adopts a laser etching production line 10 on the chromium to carry out laser etching on the chromium on the plastic workpiece; the method specifically comprises the following steps:

the feeding device 20 conveys the plastic workpiece to a designated position; the conveyor belt 200 is cleaned by the synchronous cleaning mechanism 300, and the conveyor belt 200 is wiped by the sponge wiper 325 in a manner of swinging rotation;

the feeding mechanical arm 30 grabs the plastic workpiece on the feeding device 20 onto the laser etching bearing plate 420;

the laser etching machine head 430 performs laser etching on chromium on the plastic workpiece on the laser etching bearing plate 420;

the blanking mechanical arm 50 grabs the plastic workpiece subjected to the chrome upper laser engraving to the blanking device 60;

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
