Control system of laser marking machine

Abstract

The control system of laser marking machine is set between the operator and the laser marking machine for the operator to operate the laser marking machine. The control system has one microcomputer with display device as the control center, I / O card for connection to the laser marking machine, pneumatic device and sensor, motor driving card for connection to the motor and loaded control software based on Windows operation system. The control system possesses excellent operation interface and comprehensive data acquiring and analyzing capacity, and may be used well in semiconductor industry.

Description

technical field [0001] The invention belongs to the field of laser marking machine control, in particular to a system for controlling the laser marking machine by using a microcomputer. technical background [0002] The current laser marking machine control system adopts PLC as the technical platform, but with the rapid changes and progress in the international semiconductor production field, the limitations of PLC are becoming more and more obvious, basically unable to keep up with the changes and the increasing growth semiconductor industry. [0003] Most PLC control systems have the following defects: [0004] 1. Poor data acquisition ability: Most PLCs use memory modules, such as running memory, data memory, etc. The cost of memory is high, and it is very troublesome to connect and use in software, and usually the memory of PLC does not exceed 1M, and the available space is very limited . This greatly limits its data collection capabilities, such as the tracking data ...

AI Technical Summary

Problems solved by technology

[0004] 1. Poor data acquisition ability: Most PLCs use memory modules, such as running memory, data memory, etc. The cost of memory is high, and it is very troublesome to connect and use in software, and usually the memory of PLC does not exceed 1M, and the available space is very limited

This greatly limits its data collection capabilities, such as the tracking data for each strip, the batch number data of mass production, the efficiency data of system operation, the log data of system operation, the tracking data of user's operation status, etc., cannot Easy implementation on PLC

[0005] 2. The interface is monotonous and human-computer interaction is lacking: the interface that can be used by PLC is very limited, and the PLC itself does not have an interface, and the interface is generated by touching the screen

Since there are many types and brands of touch screens, each brand has different functions and development systems, which increases the complexity of system development

It is not easy for users to get used to and accept every brand

In addition, the interface provided by the general touch screen is relatively simple and rough, which makes the design of human-computer interaction have to be subject to many restrictions. The rich and flexible interactive interface required by many operators cannot be realized, and it becomes the rigidity of the operator to adapt to the PLC. Rigid interface approach

[0006] 3. The expansion ability is not strong, and the upgrade space is small: the interface of PLC is limited, the space that can be increased is limited, the expansion cost is high and complicated, some functions such as USB cannot even be expanded, and the possibility of future expansion by users is almost zero.

[0007] 4. The professionalism is too strong, and there are many types of manufacturers, which are incompatible with each other: because of its specialization, equipment manufacturers need to train development and maintenance talents for each brand of PLC. The cost of changing brands can be imagined, and if they do not replace , it needs to develop with the development of this brand, which is undoubtedly restricted

If the equipment manufacturers manufacture different types of machines with different degrees of complexity, it is likely that there will be different PLC brands, which are complicated to purchase, difficult to maintain, and too professional to be interchangeable.
