Laser Marking System for Aluminum ID Plates and Labels for Automobiles and Operational Methods {LASER MARKING SYSTEM MARKING ID ON ALUMINIUM PLATE AND LABEL FOR A VEHICLE, AND CONTROL METHOD FOR THE SYSTEM}

The present invention relates to a laser engraving system and a method of operating the ID aluminum plate and label of a vehicle, and more particularly, to the development of a variable operating technology of the laser beam power during laser engraving of the laser marking system and label supply / stamping / cutting equipment The present invention relates to a laser engraving system of ID aluminum plates and labels of automobiles and a method of operating the same to enable the identification of two materials with one laser device.

In general, a laser engraving system applied to an automobile production process is a system for giving a unique ID to a vehicle and stamping the ID on an aluminum plate attached to an appropriate position of the vehicle.

1 shows a conventional laser engraving system.

According to FIG. 1, the laser engraving system supplies a server computer 110 for identifying a type of ID plate to be imprinted and controls a laser processing process according to the type, and an ID plate under the control of the server computer 110. It is made including the marking and laser equipment 120 to take out.

In general, the automobile production line is to produce a variety of vehicles, such as a variety of ID plate is provided with a variety of models. Thus, a specific ID plate is applied to a specific vehicle.

Therefore, the server computer 110 receives the vehicle model sequence information from the host, and is responsible for specification specification and work instruction of the ID plate to be processed by the laser equipment 120 according to the vehicle model sequence information. At this time, the ID plate is made of aluminum.

The laser equipment 120 includes a laser head 121 for irradiating a laser beam at an intensity designated by the server computer 110 appropriately for a vehicle model, and a server computer 110 having a plurality of ID plates corresponding to each vehicle model. Aluminum plate supply unit 122 for supplying the ID plate to be imprinted by the laser beam under the control of the control, and transfer the ID plate supplied from the aluminum plate supply unit 122 to the work table and adjust the relative position with the laser head 121 An aluminum plate transfer and positioning unit 123 for marking a specific pattern by the laser beam to be irradiated, and an aluminum plate taking-out unit 124 for taking out the ID plate that has been imprinted by the laser beam.

ID plates processed by the laser engraving system include identification, three types of compliance, VIN, and E-Marker.

However, new models with the ID specification changed to the label are included in the production line, and they may be mixed with existing models applied with aluminum plates. For example, in the past, the 'FC' changed to a label after the production of 'XD' and 'CPE'. Therefore, two materials, aluminum and label, must be operated by the laser engraving system.

However, since the conventional laser engraving system can process only one material per unit, newly mixed label processing is impossible. Therefore, there is a problem that two systems are installed and operated in one line by requiring a separate system for labeling.

Accordingly, there are problems caused by incidental problems such as double investment in equipment of the same use, difficulty in processing vehicle sequence data, excessive generation of ID heterogeneous work and unnecessary work lines, and difficulty in preserving equipment.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to develop a variable operating technology of the laser beam power during laser engraving of the laser engraving system and to develop a label supply / marking / cutting equipment technology. The present invention provides a laser engraving system for ID aluminum plates and labels of automobiles, which enable identification of two materials with one laser device, and an operation method applied to the laser marking system.

Laser engraving system of ID aluminum plate and label of the vehicle of the present invention for achieving the above object, the laser beam power and plate for the stamping of the first type material and the second type material by classifying the ID specification for each vehicle type according to the vehicle model data A server computer for selectively controlling the engraving process; A plate transfer stage which selects a plate of a first material and transfers the plate of the first material according to a control signal of the server computer into the laser beam irradiation area; A label film transfer stage for transferring a label of a second type of material into a laser beam irradiation zone according to a control signal of the server computer; A laser irradiator for irradiating and marking a laser beam having an intensity specified by a control signal of the server computer with respect to the plate or label conveyed by the plate conveying end or the label film conveying end; It characterized in that it comprises a take-out stage for taking out the plate or label is completed by the laser irradiation unit.

In order to achieve the above object, a method of operating a laser engraving system of an ID aluminum plate and a label of a vehicle according to the present invention is whether a server computer reads sequence data of a vehicle to be put into a marking process in a laser marking system, and is a vehicle having a second type of material. Determining whether or not; If the second kind of material does not correspond, the server computer controls the plate conveying end, the laser irradiator and the plate ejecting end to stamp and process the plate of the first kind of material; In the case of the second type of material, the server computer is characterized in that it comprises the step of stamping, cutting, and taking out the label of the second type of material by controlling the label transfer stage and the laser irradiation unit.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

2A, 2B, and 2C are schematic diagrams of a laser engraving system according to an embodiment of the present invention.

As shown in FIG. 2, the laser engraving system according to the present invention selectively classifies the ID specification for each vehicle type according to the vehicle model data to selectively control the laser beam power and the plate engraving process for the engraving of the first type material and the second type material. A server computer (not shown), plate transfer stages 211, 212 and 213 for selecting a plate of a first type material and transferring the same to a laser beam irradiation area according to a control signal of the server computer, and a control signal of the server computer. The label film conveying end (214, 215) and the plate conveying end (211, 212, 213) or the label film conveying end (214, 215) for conveying the label of the second type material into the laser beam irradiation zone according to The laser irradiator 218 and the laser irradiator 218 for marking the plate or label to be irradiated with a laser beam of intensity specified by the control signal of the server computer are completed. It comprises a take-out end (216, 217) for taking out the rate or label.

In addition, it may further include an operation panel 219 for enabling smooth operation control of the system or an arbitrary operation by an operator, a cover 220, and a main frame 221 for fixed support of the system.

And the first type material and the second type material to be engraved indicate the material of the aluminum plate and the label, respectively.

The server computer exchanges data with an external storage medium or a host computer to process vehicle model data. Therefore, a communication function for data communication must be implemented. This function can be achieved by performing Ethernet communication in a general server / client structure.

In addition, the operating system of the server computer may apply a commercially available Windows NT, etc. to enable a large number of host connections, and has an appropriate application program to variably operate the laser beam power according to the ID specification when laser engraving.

For example, in the case of an application program, a program called 'HMCIF3' can be used to distinguish between vehicle class data processing and vehicle ID specification through Ethernet communication. At this time, ID specification by vehicle type is 6 kinds including aluminum plate / label, country specification, etc. Also, a program called 'NT MARKER' can be used to control laser marking, laser beam power variable control according to material, and laser cutting of an outline when labeling.

However, depending on the operating environment, the functions as illustrated above may be achieved by one application program without distinguishing the application programs within the server computer.

In addition, the plate conveying end (211, 212, 213) is a hopper for loading six kinds of aluminum plate according to the ID specification for each vehicle type, and to draw out a specific type of plate from the plate loaded on the hopper 211 And a plate conveying conveyor 213 for conveying the plate drawn by the plate absorber 212 into the laser beam irradiation area. Thus, if it is required to imprint the ID of a specific vehicle type by the server computer, the plate adsorber 212 withdraws the plate corresponding to the vehicle type from the hopper 211 and moves to the laser beam irradiation area by the plate transfer conveyor 213. Act as a transported system.

The label conveying stages 214 and 215 are a label film 215 wound up to continuously feed labels, and a label film feeder 214 for conveying the label film 214 into the laser beam irradiation area in accordance with a control signal from a server computer. ) Preferably, after the label is continuously supplied in the form of a film is imprinted, it is configured to further include a label cutting press 222 connected to the label conveying end (214, 215) for cutting separately for each vehicle.

An operation method applied to the laser engraving system as described above will be described.

3 is a flow chart of a laser engraving system operating method according to an embodiment of the present invention.

According to FIG. 3, the server computer reads or receives the vehicle data to be laser engraved from the outside using a communication means (S310).

Based on the vehicle data input in step S310, the server computer determines which material to process. This determination can be determined by simply checking whether or not the vehicle is a label. So the server computer is determined by the aluminum plate or label (S320).

When it is determined that the aluminum plate according to the condition of the step S320, the server computer distinguishes which of the six types of ID specifications of the vehicle model (S330, S331).

After step S331 is performed, the server computer determines the laser power conforming to the determined ID specification and starts handler control. The handler at this time refers to laser engraving equipment other than the server computer. This is as follows (S332, S333).

In the handler started in step S333, the hopper 211 supplies six kinds of aluminum plates according to ID specifications, and the plate is transferred to the laser beam irradiation area via the plate adsorber 212 and the plate conveying conveyor to adjust the laser engraving position. (S334, S335).

When the plate is set at the stamping position according to step S335, the laser irradiation unit 218 may stamp the aluminum plate to correspond to the corresponding vehicle model. Then, the stamped plate is taken out by the plate taking-out ends 216 and 217, thereby completing the plate marking for the first vehicle of the specific vehicle type (S337).

When step S337 is performed, the server computer returns to S310 to read data of the next vehicle.

The aluminum plate engraving process is thus performed.

On the contrary, if it is determined in step S320 that the vehicle is a label, the server computer distinguishes among the six types of ID specifications of the vehicle model (S340 and S341).

After step S341 is performed, the server computer determines the laser power conforming to the determined ID specification and starts handler control. The laser power determined at this time will be different from the laser power determined for the aluminum plate in step S332 under normal conditions (S342 and S343).

In the handler started in step S343, the label film feeder 214 supplies a label film 215 conforming to the corresponding ID specification. Therefore, in the case of six types of ID specifications, six types of label films are provided. At this time, since the label film 215 is continuously supplied, the label film feeder 214 performs the labeling feed length and engraving position setting (S344).

When label supply and marking position setting are made in step S344, the laser irradiation unit 218 irradiates the laser beam with the beam power determined in step S342 so that the marking corresponding to the ID specification determined in step S341 is performed (S345).

The label imprinted in step S345 may be immediately taken out, but preferably, the laser irradiation unit 218 laser cuts the outline of the label and cuts each label for each vehicle (S346, S347).

When the label is taken out in step S347, the server computer returns to step S310 to read data of the next vehicle.

However, when an application of the server computer is operated by being divided into 'HMCIF3' and 'NT MARKER', steps (S310 to S320, S330, S331, S340, and S341) are assigned to 'HMCIF3', and steps (S332, S333, S342 and S343) may be separated and operated efficiently by the 'NT MARKER'.

According to the laser engraving system of the ID aluminum plate and label of the vehicle of the present invention described above, it is possible to simultaneously supply / stamp / cut / take out the aluminum plate and label by enabling the variable operation of the laser beam power according to the material to be imprinted. It works.

In addition, the present invention has the effect of preventing the overlapping investment of equipment by stamping the ID of the vehicle of two materials with one laser equipment.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Therefore, the above embodiments do not limit the scope of the claims.
