Problems solved by technology

[0002] In the process of silicon material processing, it is often necessary to use diamond wire for cutting. The diamond wire is released from the take-up and pay-off roller on one side, and then goes to the cutting wheel train after being driven by multiple gear trains in the middle, and then passes through the other wheel train from the cutting gear train. The process of reaching the take-up and pay-off roller 2 on the other side after the transmission of multiple gear trains; due to the existence of multiple motor-driven gear trains such as the take-up, pay-off and cutting gear trains, the driving gear train driven by the motor is due to the synchronous control of the speed and the wheel As a result, the diamond wires in the process of passing through these wheel trains, the linear speed is difficult to keep completely consistent, resulting in a certain speed difference between the diamond wires between the wheel trains, which will cause the diamond wires between the wheel trains to be tensioned or Relaxation, resulting in tension fluctuations, such tension fluctuations will affect the cutting quality, and seriously affect the life of the diamond wire, causing the diamond wire to break
[0003] The traditional tension adjustment is to set the tension swing lever mechanism between the take-up and pay-off roller 1 and the side cutting wheel and the other side cutting wheel and the take-up and pay-off roller 2 respectively, the tension swing lever drives the tension wheel to deflect, and through The passive rotary motion of the tension wheel is used to adjust the speed difference of the diamond wire on both sides of the tension wheel in real time, so as to balance the tension difference between the wire roller and the cutting wheel system; one end of the swing rod is equipped with a motor, and the other end is set with a tension wheel, and the tension swing rod The motor is set to a constant torque output, and the torque is converted into the force of the tension wheel through the swing rod to balance the tension. However, when the swing rod is used to adjust the tension, the influencing factors on the tension fluctuation include: the swing rod mechanism and The moment of inertia of the motor rotor, the angle of the swing rod, the spacing of the wheel train, etc., due to many influencing factors, the error in the tension adjustment process is relatively large

Embodiment 1

[0031] Embodiment 1: A diamond wire tension adjustment mechanism, see attached figure 1 , including a tension wheel 1 and a thrust application mechanism 2 that applies a thrust to the tension wheel 1; there are two tension wheels 1, wherein the tension wheel 1 is located at the cutting side of the take-up and pay-off roller one 3 and the side near the take-up and take-off roller one 3 Between the wheels 5, another tension wheel 1 is located between the take-up and pay-off roller two 4 and the cutting wheel 5 near the side of the take-up and take-off roller two 4; The tensile force of the diamond wire received by the tension wheel 1 and the thrust applied by the thrust applying mechanism 2 are in a straight line. When the tension applied by the diamond wire of the tension wheel 1 and the thrust are in a balanced state, they are equal in magnitude and opposite in direction; 1 can move along the straight line where the thrust is located.

Embodiment 2

[0045] Embodiment two: a diamond wire tension adjustment method, comprising the following steps:

[0046] Determining thrust: according to the formula Calculate the thrust F T ; Among them, F is the diamond wire tension, N; F T is the thrust of the linear motor, N; m 1 The mass of the mover of the linear motor, kg; v 1 and v 2 Respectively, the linear velocity m / min of the diamond wire on both sides of the tension wheel 1; Ff is the friction force of the linear motor, N; V line is the moving speed of the linear motor mover, m / min;

[0047] Apply thrust: according to the calculated thrust, apply a constant thrust to the tension wheel (1) through the linear motor;

[0048] Mechanism operation: During operation, when the tension exerted by the diamond wire on the tension wheel changes, the balance at the tension wheel (1) is broken, and the tension wheel (1) moves until the tension wheel (1) receives the tension until it is balanced again with the thrust exerted by the li...

Abstract

The invention discloses a diamond wire tension adjusting mechanism. The diamond wire tension adjusting mechanism is characterized by comprising two tension wheels, and the two tension wheels are located between a take-up and pay-off roller I and a cutting wheel close to one side of the take-up and pay-off roller I and between a take-up and pay-off roller II and a cutting wheel close to one side ofthe take-up and pay-off roller II respectively; and a thrust applying mechanism used for providing thrust in a linear direction for the tension wheels; tension of a diamond wire acting on the tensionwheels and the thrust provided by the thrust applying mechanism are located on the same straight line, and the tension wheels can reciprocate in the straight line direction where the thrust is located; and the tension is adjusted by applying pushing force in the linear direction, only two factors influencing tension fluctuation exist during tension adjustment, and tension adjustment is more accurate.
