Embodiment Construction

[0012] like figure 1 The synchronous servo drive and constant tension control system of the multi-wire cutting machine shown includes the industrial computer 1, the main servo motor 2, the slave servo motor 3 and the take-up and release servo motor 4, and the industrial computer and each servo drive are connected through Profibus high-speed data For transmission, firstly, the industrial computer sets a standard given value, and the given value is transmitted to the main drive servo, and at the same time, the given value and the actual data and status of the main drive are quickly transmitted to the three slave drive servos and the take-up and release reel servo. In terms of hardware, the industrial computer and the servo are respectively designed with synchronization function option boards, and in terms of software, it depends on the synchronization characters of each message (such as figure 2 As shown), each frame message transmitted on the bus contains a synchronization cha...

Abstract

The invention relates to a control system for a multi-wire cutting machine. A multi-wire cutting machine synchronous servo drive and constant tension control system includes an industrial personal computer, a main serve motor, a secondary serve motor and a take-up and pay-off serve motor. The invention is characterized in that the industrial personal computer sets a standard specified value which is sent to a main servo drive, at the same time, high-speed data transmission is carried out between the industrial personal computer and each servo drive via Profibus, the specified value and the data of the main drive are quickly sent to three secondary drive serve motors and the take-up and pay-off serve, the dependence on the synchronous character of each message is synchronously realized, the value synchronous with the main servo is calculated by the take-up and pay-off serve according to the above data and the diameter of the prior take-up reel and the line tension in the industrial personal computer, and the result is transferred to the take-up and pay-off serve via the Profibus bus.

Description

1. Technical field: [0001] The present invention relates to wire cutting machines, in particular to their control systems. 2. Background technology: [0002] Multi-wire cutting machine is a machine that uses thin steel wire cutting wire to cut hard and brittle materials such as monocrystalline silicon. A constant tension is given in the wire mesh, and then the cutting wire mesh is run at a high speed, and finally fine emery mortar is sprayed on the cutting wire mesh, and at the same time, the feeding table drives the cutting wire mesh to feed to complete the cutting task. [0003] The normal operation of the wire mesh requires the synchronization of the height of multiple servo motors to ensure that the diameter of the wire wheel for releasing the cutting wire and the wire wheel for receiving the cutting wire changes continuously during the operation of the cutting wire. To keep the tension of the wire mesh unchanged, it is necessary to The speed and torque of the pay-off a...
