With the rapid development of market demand, the PCB industry's requirements for production capacity are increasing day by day. In order to rapidly increase production capacity on the premise of ensuring quality, a new revolution has been launched in the field of PCB exposure, that is, the UVLED transformation of traditional exposure machines, and the use of UVLED light sources to replace traditional mercury lamps. At present, the traditional line exposure machines on the market have already undergone large-scale UVLED transformation, and the exposure machines are also following, ushering in a new wave of transformation!
Exposure machine refers to a device that transfers the image information on film or other transparent bodies to the surface coated with photosensitive material by turning on the light to emit ultraviolet rays of UVA wavelength.
The touch screen is the automatic control system of the exposure machine, including the scheme of the control system, the hardware configuration, the address assignment of the PLC input and output points, and the software control program. The system can well meet the production and manufacturing needs of enterprises, and has a high degree of automation and good reliability. Features, improve the production quality and efficiency of the exposure machine.
(1) Operation button control: Select the control, and drag a frame of the required size anywhere on the screen, that is, the control is established. The screen jump can be realized without the participation of the user's MCU program. The user program can also control button functions, switch press and pop, custom button functions, etc.
(2) Bit switch control: Operate, monitor and display the specified PLC or HMI bit address; when the bit switch is pressed, the bit value of the operation address will change as described by the switch type.
(3) Radio button control: Operate, monitor and display the specified PLC or HMI byte or word address; when the radio button is pressed, the bit value of the operation address will change according to the set value.
(4) Real-time data control: It is used to display or modify the values stored in the data registers in PLC or other connected devices, such as speed, current, pressure, etc. Custom fonts can be used for personalized display.
(5) Dynamic picture control: change the picture according to the corresponding value change of PLC or single chip variable address), display the current value in the form of picture, can control the animation play, stop, pause, play the previous frame, the next frame and the specified frame, and can also control the animation The picture is controlled by movement and moves according to a predetermined trajectory.
(6) Curve control: The user MCU only needs to send AD sampling data, the serial screen will automatically fit and display it dynamically.
