The control system of the high-speed computer panel saw has the advantages that:

the control system of the high-speed computer panel saw adopts bus control, and reduces the production cost while considering quick response and the processing precision and stability of equipment.

The control system is divided into a plurality of large module units, namely a feeding device control unit, a pushing device control unit, a front aligning plate device control unit, a main work clamping and feeding device control unit, a sub work clamping and feeding device control unit, a synchronizing device control unit, a side aligning plate device control unit, a pressing device control unit, a cutting device control unit and the like, and each module unit is divided into a plurality of small control units, wherein the small control units are controlled by specific parts.

The large module unit can be designed into an open type and modular structure, has a standardized interface, can be connected with a standardized interface and a remote I/O on a programmable controller (P L C), and has the advantages of universality of hardware and software, high compatibility and strong portability.

Each module has an independent function, modules of the same kind can be reused and interchanged in a product family, and different combinations of rows of related modules can process products of different specifications.

Products with different requirements can be created by selecting and matching the combination configuration of various functional modules, so that the customization requirements of customers are met, and the requirements of the customers on different configurations and the market requirements can be flexibly met; the reuse of the similarity can facilitate the purchasing, manufacturing and maintenance of the whole product.

Modularization, the functions are decomposed, and the coupling performance between the functions is reduced. Therefore, in order to replace a certain module to improve the quality or efficiency, the whole structure cannot be changed, and the workload can be obviously reduced only by changing the corresponding module, so that the application of modularization is the ultimate design of each industry. The modular structure thus has interoperability and portability between machine tools. By providing a standardized interface, communication and interaction mechanism, different function module functions run on a system platform by a standard application program interface, and equal interoperation capacity is obtained to coordinate work. The unified data format, interaction model and control mechanism are applied, each function module forming the system can come from different developers, and each function module can run on hardware platforms provided by different suppliers through consistent equipment interfaces, thereby being beneficial to shortening the development period, controlling the development cost and the like.

The advantage of dividing each module into a plurality of small control units is:

1. the structure is more reasonable: the control system of the machine adopts each module to be divided into a plurality of small control units, the layout of each small control unit is more reasonable and scientific, the functions of each part can be well exerted, and the service life of the machine is prolonged.

2. Designing an optimization control system: each part of the control system is designed into a small control unit, and then a plurality of small control units are combined into a module, so that the design of the control system can be simplified and optimized.

3. The maintenance is simpler: each part of the machine is a small control unit, the machine has problems, the diagnosis can be quickly carried out, only the corresponding small control unit needs to be replaced, and the operation is simple.

Because the auxiliary clamping and feeding device control unit is added, two kinds of plate sawing with different lengths can be finished by one set of cutting device and the same sawing, and the efficiency can be improved by about one time.

The control system with the structure has the advantages of fast response, high processing precision, stable work and reliable operation. The control system with the structure has better compatibility by matching the control elements, thereby leading the operation to be more stable and reliable.
