Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the embodiments given in the accompanying drawings.

[0022] refer to figure 1 As shown, a protection method for avoiding collision of the cutting head in this embodiment includes the following steps:

[0023] Step 1, setting the sensor 1 on the side of the cutting head, and communicating the sensor with the servo motor driving the cutting head;

[0024] Step 2: Obtain the maximum moving speed of the cutting head, obtain the maximum response delay time of the servo motor, and calculate the minimum safety distance of the sensor 1 according to the following formula:

[0025] d=s*t;

[0026] In the formula, d is the minimum safety distance perceived by sensor 1, s is the maximum moving speed of the cutting head, and t is the maximum response delay time of the servo motor;

[0027] Step 3: Start the sensor 1 to detect obstacles in front of the cutting head when the cutting head is moving....

Abstract

The invention discloses a protection method for avoiding collision of a cutting head. The protection method comprises the following steps that firstly, the side of the cutting head is provided with asensor, and the sensor is in communication connection with a servo motor driving the cutting head; secondly, the maximum movement speed of the cutting head is acquired, the maximum response delay timeof the servo motor is acquired, and the minimum sensing safety distance of the sensor is worked out according to a following formula; and thirdly, the sensor is started and detects a barrier in frontof the cutting head when the cutting head moves. According to the protection method for avoiding collision of the cutting head, by means of the arrangement of the first step, the second step and thethird step, the purpose that the cutting head is provided with the sensor, then, the servo motor is stopped in time after the senor senses the barrier, and the problem that the cutting head collides with the barrier and consequently the cutting head is damaged is avoided can be effectively achieved.

Description

technical field [0001] The invention relates to a protection method, in particular to a protection method for avoiding collision of cutting heads. Background technique [0002] In the laser cutting industry, due to the uneven cutting surface or other obstacles, the collision of the laser cutting head will often occur. If it hits the body of the cutting head, the cutting head may be damaged when the speed is relatively fast, causing huge Economic losses. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a protection method for avoiding collision of the laser cutting head which can effectively avoid the collision of the laser cutting head. [0004] In order to achieve the above object, the present invention provides the following technical solution: a protection method for avoiding collision of the cutting head, comprising the following steps: [0005] Step 1, setting a sensor on the side of t...
