The blue screen of the automatic fiber laser cutting machine system frequently prevents repairs
Following the intelligent development of the home appliance industry, in the production process of electrical appliances, the sheet metal and parts requirements are becoming more and more dense, and the styles are complicated and the craftsmanship is more difficult. The technology of fully automatic fiber laser cutting machine can meet the above needs. From the perspective of industrial development, the deep application of laser cutting in the home appliance industry will become a trend.
Since its birth, the automatic fiber laser cutting machine has been continuously popular in society because it has a wide range of applications, from very simple sheet metal processing to billboard cutting, metal lighting, kitchenware and bathroom industries, etc. Laser cutting is indispensable. Do you know that the metal parts and electrical cabinets of the household appliances we use every day are cut out by laser.
Parts processed by sheet metal almost account for more than 30% of all product parts. The ancient techniques such as cutting, cutting corners, opening holes and trimming are left behind, which simply affects product quality and production costs. The automatic fiber laser cutting machine has the incomparable naivety and processing accuracy of ancient processing methods, because it adopts 'non-touch processingTherefore, laser cutting technology can effectively improve product quality, reduce production costs, reduce task intensity, improve ancient plate processing technology, and bring better production benefits to manufacturers.
The principle of the equipment system of the automatic fiber laser cutting machine: power-on is guided by the DOS operating system of the industrial computer, through the 232 communication interface and the establishment of the single-chip microcomputer. The machine tool masters the system and the control panel The function is imported into the industrial computer for equipment control and programming. At this time, the system indicator displays the information of the machine tool to control the system.
Interference signs: the operation feedback is found to be stupid during the operation of the equipment until there is no feedback on the system operation or the system is powered on. After the implementation of the DOS system guidance, the system blue screen, and there is no feedback on operation.
Inspection process: I started to question the 386XT industrial control function due to the obstruction signs. After checking the computer power supply, the voltage of the power supply is usually continuous and reliable, and the power supply is only normal when it is loaded. The memory, interface board, hard disk, and graphics card were also checked, and the computer was thoroughly maintained. The obstacles to the test machine still exist. The frequent investigation system starts blue screen and the operation is slow and obstructs the process. I feel the obstacle is probably in the single-chip unit. Unplug the CPU board from the single-chip unit frame. Frequent measurement of the on-board chip compared to the chip drawing reveals doubts, because the obstructive signs Occasionally, in an environment where the obstructing chip cannot be found, the connection obstruction signs based on the principle of the MCU may indicate that there is a malfunction in the associated chip of the data transmission joint. SAB8286A (8-bit bus data transmission and reception) and SAB8287A (8-bit bus) have been changed successively. Data transceiver), SAB8282A (8-bit data latch), SAB8283A (8-bit data latch) and other chips, but the obstacles still exist. At this time, I also feel that the blindness of the questionable chip replacement is too large and the rate is too low.
