The invention is mainly used for cutting artificial fiber boards in the plate furniture manufacturing and woodworking industries, and comprises the following main working steps:

firstly, automatic feeding is performed by using a feeding device: stacking a plurality of plates together on a lifting table of a feeding frame, wherein the stacking height of the plates is not more than mm; then, the computer control system controls the lifting platform to work, so that the lifting platform lifts the piled plates together by a plate thickness distance, and at the moment, the plate positioned at the top of the lifting platform protrudes above the plane of the feeding frame; then, the computer control system controls the second propelling mechanism to work, so that the second motor drives the second cross beam to move forwards along the second track through the second transmission shaft, the push block assembly is propped against the rear end face of the plate material and synchronously moves forwards along with the second cross beam, the plate material is enabled to move forwards into the feeding frame, and after the plate material is completely fed into the feeding frame, the computer control system controls the second propelling mechanism to reset backwards.

Then, the pressing device and the cutting device are matched for cutting the plate positioned on the workbench: when the plate is fed into a channel of a workbench according to the required size of a workpiece, the first pushing mechanism stops working, then a computer control system controls a pressing device to work, so that a pressing beam moves downwards to be pressed on the upper surface of the plate under the action of a first driving cylinder body, the plate is pressed and positioned, if the plate is required to be pressed and positioned better, a third electrode can drive a movable seat to move to a proper position along a linear guide rail, and a second driving cylinder body is pressed down to the plate, and the plate is pressed and positioned; then, the cutting device is controlled by the computer control system to work, the main motor drives the main saw blade to rotate, and the auxiliary motor drives the auxiliary saw blade to rotate, so that the plate is cut, a workpiece is obtained, and the workpiece is output to the discharging table; then resetting the cutting device and the pressing device, and then enabling the first pushing mechanism to work again, so that the plate moves forward by one workpiece length, and then repeating the actions, and cutting the plate by using the pressing device and the cutting device until the plate is completely cut into a plurality of workpieces.

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 leveling plate device control unit, a main work clamp feeding device control unit, a secondary work clamp feeding device control unit, a synchronous device control unit, a side leveling 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 which are controlled by specific parts. When the main clamp feeding device and the auxiliary clamp feeding device asynchronously move to realize that plates with different lengths are cut at the same time, a part of auxiliary clamp mechanisms can realize upward overturning avoidance and a part of auxiliary clamp mechanisms can realize downward overturning clamping of the plates, so that a computer plate cutting saw can complete sawing of plates with two different lengths at the same time, and the efficiency can be doubled.

The large module unit can be designed into an open and modularized structure, has a standardized interface, can be connected with a standardized interface and a remote I/O on a Programmable Logic Controller (PLC), has universality for hardware and software, and has high compatibility and strong portability.

Each module has independent functions, the modules of the same kind can be reused and interchanged in the product family, and products with different specifications can be processed by different combinations of related module rows.

By selecting and matching the combined configuration of various functional modules, products with different requirements can be created, the custom-made requirements of customers can be met, and the requirements of customers on different configurations and the market requirements can be flexibly met; the reuse of the similarity can make the purchase, manufacture and maintenance of the whole product more convenient.

And the module is modularized, so that functions are decomposed, and the coupling property between the functions is reduced. Therefore, in order to replace a certain module to achieve the improvement of quality or efficiency, the whole structure is not changed, and the workload is obviously reduced only by changing the corresponding module, so that the modularized application is the final design of each industry. The modular structure thus provides interoperability and portability between machine tools. By providing standardized interfaces, communication and interaction mechanisms, different function module functions are operated on a system platform through standard application program interfaces, equal interoperable capacity is obtained, and the functions are coordinated. The system has the advantages that the unified data format, interaction model and control mechanism are applied, each functional module forming the system can be sourced from different developers, and each functional module can be operated on hardware platforms provided by different suppliers through a consistent equipment interface, so that the development period is shortened, the development cost is controllable, and the like.

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

1. the structure is more reasonable: the control system of the machine is divided into a plurality of small control units by adopting each module, so that 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. Design of an optimal control system: each part of the control system is designed into a small control unit, and 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. Maintenance is simpler: each part of the machine is a small control unit, the machine has problems, can be diagnosed quickly, only needs to replace the corresponding small control unit, and is simple to operate.

Due to the fact that the auxiliary work clamp feeding device control unit is added, two kinds of plates with different lengths can be sawed at the same time only by a cutting device, and efficiency can be doubled.

The control system with the structure has the advantages of quick response, high processing precision, stable operation and reliable operation. The control elements of the control system with the structure are matched for use, so that the compatibility is better, and the operation is more stable and reliable.

The working method of the computer board cutting saw has the beneficial effects that:

by adopting the working method, the logic is clear, and when a plurality of devices are used or not used, simultaneously or not used, and simultaneously or not simultaneously act in a plurality of ways, each motion device can be ensured not to interfere in the processing process, so that the motion is very reliable; and the control program design of the control system is greatly simplified, so that the design difficulty of the control system is greatly reduced. By adopting the working method, the work piece is processed in the most reasonable and most efficient mode by complex actions such as multiple processing modes, front feeding or rear feeding and the like which relate to multiple processing devices, and the working method has the advantages of reliable and efficient movement and low cost which can be realized by a control system.

The control system and the working method of the structure can realize the feeding and plate feeding program before starting or the feeding and plate feeding program after starting only by inputting processing patterns, replacing processing programs and the like, can select a main working clamp working mode and an auxiliary working clamp working mode according to the requirements, can select whether to start a backup plate running program and the like, can realize the feeding after using the feeding device or the feeding before manual operation, can realize the independent feeding of the main working clamp feeding device or the independent feeding of the auxiliary working clamp feeding device or the synchronous feeding of the main working clamp feeding device and the auxiliary working clamp feeding device or the asynchronous feeding of the main working clamp feeding device and the auxiliary working clamp feeding device, can realize various processing modes, can not interfere when various motions are carried out simultaneously or not simultaneously, and can realize reliable motion, stable running and high processing precision, thereby automatically processing plates with different sizes into workpieces with different sizes, greatly meeting the requirements of different sizes of customized furniture and greatly improving the working efficiency and intelligent control degree of computer saw equipment.
