The handheld laser welding control system operating panel (HMI) adopts a 7-inch configuration TFT touch screen with a beautiful interface and convenient operation. It allows setting laser-related parameters, monitoring input and output IO status, alarm information, and motion state in real-time.

Key HMI Functions:

• Scanning Parameters: Used to set relevant parameters during galvanometer scanning processing.
• Број параметра: The system supports the storage of 9 groups of parameters.
• Брзина скенирања: Used to set the scanning speed of the galvanometer.
• Снага ласера: Set the output light power during welding.
• Scanning length: Used to set the length of the laser scanning in the X direction.
• Ширина скенирања: Used to set the width in the Y direction of the laser scanning.
• Тип скенирања: Used to set 5 types of scanning waveforms.
• Red Light | On/Off: Controls the red light switch, indicating the red light of the laser.
• Allow/Prohibit | Laser Emission: This button allows or prohibits laser emission.
• Manual Blowing: Clicking on the manual blowing area will continue the blowing process. Clicking it again will turn off the blowing.

5.2 HMI Operation Introduction

The HMI allows for various parameter adjustments and system controls.

• System Parameter Settings: After parameter modifications, they need to be saved to take effect.
• Early Vent Time: When starting the processing, a delayed vent can be set. When the external start button is pressed, air is blown and delayed for a period of time, and then the laser starts to come out.
• Delayed Gas Shut-off Time: When processing stops, a delayed gas shut-off can be set. When processing is stopped, first stop the laser output, delay for a period of time, and then stop the air blowing.
• Opening Power: Used to set the initial power of the laser, which is a percentagе снаге заваривања.
• Progressive Opening Time: Controls the time it takes for the laser's output to slowly rise to the set power.
• Light-off Power: Used to set the light-off power of the laser, which is a percentagе снаге заваривања.
• Progressive Turn-off Time: The time used to control the slow decrease of the laser's turn-off power.
• Језик: Used for switching languages.
• The length of the early deceleration: Control the distance of the early deceleration in the gradual time of turning off the light.
• Фреквенција ласера: Used to set the PWM frequency of the laser.
• Радни циклус: Set the duty cycle of the PWM modulation signal, with the setting range being 1% ~ 100%.
• Double-click light output enable: Select the light output mode and whether to double-click the button. If not enabled, click the button.
• Enable security lock: Select whether to perform security lock protection.
• Proportional coefficient: Used to set the maximum range of the X-axis and Y-axis of the galvanometer. This parameter needs to be consistent with the actual range of the galvanometer; otherwise, the actual light output length and width may not be accurate. The default parameter does not need to be set.
• Field lens type: Reserved for switching between different field lenses. Reserved parameters do not need to be set.

7. Troubleshooting and Alarm Information

7.1 Monitoring Protection Device

The system includes monitoring for protective lens temperature. To set the temperature alarm limit:

[Home Page]→[System Parameter]→[Equipment Parameter]→[Input Password: 666888]→next page→ lens temperature alarm limit value.

Предлаже се да се подешена вредност температуре сочива подеси на 50. Након што температура сочива пређе подешену вредност, на почетној страници ће се појавити аларм упозорења и светло дисплеја на страни ручног виска ће постати црвено.

7.2 Информације о аларму

The alarm information includes: safety clip alarm and machine alarm. The safety clamp alarm is caused by the safety clamp not being reliably connected to the cleaning head.

The machine alarms include three types: laser alarm, water-cooling machine alarm and low voltage alarm. In the alarm information interface, multiple alarm messages can be displayed, with a maximum of 3 pages. They can be switched between the previous page and the next page.

When the alarm is triggered, the laser output will be stopped at this time, the galvanometer will stop moving, and the corresponding alarm information will be prompted. Users can check the relevant hardware problems and clear the alarm according to the alarm prompt. After the alarm is cleared, the alarm record of the machine's alarm will still exist in the alarm information. At this time, you can manually clear the alarm by entering the alarm information interface. If the alarm is not cleared, it will continue to prompt when the alarm is manually cleared.
