The use and common problems of laser marking machine

The use of laser marking machine.

The steps to start the laser marking machine are as follows: .

2. Check the power cord of the marking machine to make it connected correctly and reliably.

3. Insert the key switch, turn it 90o clockwise to the 'on' position, connect the main power supply, and the power indicator light is on.

4. Confirm that the laser head mushroom button (emergency stop switch) is in the pressed state.

5. Turn on the computer monitor and power switch of the computer host.

6. Rotate the red mushroom button in the direction of the arrow to make it pop up, and the laser head can be powered on. After about 1 minute, the laser head starts to complete.

7. Remove the lens cover. At this point, the laser marking machine is turned on, and the marking operation can be carried out by the operator's command.

Second marking operation.

1. Double-click the marking program icon to enter the program.

2. Select the marking file, double-click the date and time in the content to modify, and click OK to complete the modification.

Three marking tests and printing positions.

1. Place a test piece equal to the height of the marked workpiece on the workbench or production line of the laser marking machine (Z. it is better to choose the marked workpiece as the test piece ), and confirm that the test piece is indeed stable.

2. Mark by operating the marking control software. In order to make the marking effect best, the following steps can be adjusted: .

Fourth, adjust the focal length by adjusting the light head lifting device.

2. Adjust parameters such as power and marking speed in the marking software.

3. Enter the software, double-click the print date, drag up and down with the mouse, and adjust the print position to the appropriate position.

3. After completing the above steps, the printing test can be performed.

4. After the test is correct, re-mark on the workpiece.

Five shutdowns.

After the production task is completed, the operation steps for closing the laser marking machine are as follows: .

1. Press the red mushroom button (emergency stop switch) to cut off the power of the laser head.

2. After confirming that the industrial computer is not running any software, exit normally and shut down.

3. Rotate the key switch 90o counterclockwise to the 'off' position of the UV laser marking machine, turn off the main power of the marking machine, and the power indicator light is off.

4. Unplug the key and have someone keep it for next use.

5. Close the lens cap.

1. The marking pattern of the laser marking machine is partially unclear.

(1), the solution: check whether the thickness of the molded plate is uniform, whether the molding pressure is too small, whether the temperature is too low, and whether the machine accuracy is reduced.

(2), the key points of process control: the thickness error of the die plate should be controlled at 0. Within 001mm, the hardness should be kept at 230-280N/mm, because the hologram is molded to form interference fringes by applying a certain pressure to the molding roller. If the hardness of the molding plate is not enough, the internal stress during the imprinting process will cause the molding plate to be pressed. deformed or damaged.

2. The logo pattern of the laser marking machine is dull and dull.

(1), solution: check whether the heating temperature is too low and the molding pressure drops.

(2), the key points of process control: the setting of the molding pressure should comprehensively consider the pressing temperature of the mold IC automatic laser marking machine, the type of holographic material or the softening point of the coating layer The situation of the moulded plate, etc., the pressure is too high, the moulded plate is easily damaged or the holographic material is crushed, the pressure is too low, the moulded image is unclear and incomplete, for the round pressing method, the initial pressure of the pressure rollers on both sides is generally 0.08MPa After the molding starts, gradually increase the pressure of the pressure roller evenly to 030-0.50MPa, and the molding speed can be comprehensively adjusted according to the printing quality and machine performance.

3. The logo pattern of the laser marking machine is whitish.

Solution: Check whether the molding speed is too slow and the molding temperature is too high.

4. Labeling film sticker for laser marking machine.

Cause: The hot pressing temperature is higher than the degradation temperature, and the viscosity of the coating will increase, which will cause the film to stick to the plate and wrap the film on the holographic embossing roller. Solution: reduce the Hot pressing temperature.

5. The logo pattern of the laser marking machine is clear and fuzzy.

Cause: The temperature distribution of the hot pressing device is not uniform or the molding plate is not flat.
