DETAILED DESCRIPTION

[0012] In order to make the content of the application more easily understood, the application will be further described in detail according to the specific embodiments.

[0013] The application embodiment provides a device for improving the precision of the laser cutting machine, which comprises a monitoring module, a main control module and a display module. The monitoring module tracks the running track of the laser detection point in real time. The main control module detects whether the precision of the running track meets the requirements, so as to ensure that the cutting parameters are accurately executed.

[0014] Specifically, the monitoring module comprises a monitoring camera, which is fixedly installed on the cutting head of the laser cutting equipment through a mounting bracket and moves synchronously with the cutting head. The monitoring camera faces the cutting area of the cutting head. The monitoring camera is used for tracking and monitoring the image data of the area where the infrared detection point of the laser cutting equipment is located, and does not affect the running track of the cutting head.

[0015] Preferably, to prevent the monitoring camera from being deviated during the movement of the cutting head, a tripod is used to reinforce the monitoring camera after the optimal tracking angle of the monitoring camera is determined.

[0016] The monitoring module is configured to track image data of an area where the infrared detection point of the laser cutting device is located. The monitoring module includes a display screen. When the display screen is installed, the installation position of the screen is determined first, and then a bracket is made for installation. After installation, the installation height is calibrated to ensure that the monitoring display interface and the operation table interface are at the same height, facilitating the synchronous development of monitoring and operation by the operator.

[0017] The main control module is configured to receive the image data transmitted by the monitoring module, and obtain the actual cutting path of the steel plate based on the image data. Meanwhile, the main control module is also configured to obtain the preset cutting parameters based on the steel plate number, and obtain the preset cutting path of the corresponding steel plate based on the preset cutting parameters, and obtain the deviation degree of the actual cutting path of the steel plate and the preset cutting path.

[0018] It should be noted that the main control module can collect image data of the identification position of the steel plate through the monitoring module, and obtain the current steel plate number and the preset cutting parameters based on the image data of the identification position.

[0019] In addition, the device for improving the precision of the laser cutting machine also includes an alarm module. When the main control module determines that the deviation degree of the actual cutting path of the steel plate and the preset cutting path is greater than a threshold value, an alarm signal is generated and transmitted to the alarm module. The alarm module responds to the alarm signal transmitted by the main control module and reminds the operator to handle it.

[0020] The embodiment of the present application also provides a method for improving the precision of a laser cutting machine, which comprises the device for improving the precision of the laser cutting machine described above. The method specifically comprises the following steps: Step S101: control the laser cutting device to move to the identification position of the steel plate, and obtain the current steel plate number and the preset cutting parameters.

[0021] Step S102: control the laser cutting device to perform cutting operation according to the preset cutting parameters, and track the image data of the area where the infrared detection point of the laser cutting device is located during the cutting operation.

[0022] Step S103: obtain the actual cutting path of the steel plate based on the collected image data, and obtain the preset cutting path of the steel plate based on the preset cutting parameters.

[0023] Step S104: compare the actual cutting path of the steel plate with the preset cutting path, and generate an alarm signal when the deviation degree of the actual cutting path of the steel plate and the preset cutting path is greater than a threshold value, reminding the operator to handle it.

[0024] Therefore, the technical scheme of the application tracks the movement process of the cutting head through the monitoring module, acquires the actual cutting path of the steel plate, and compares it with the preset cutting path of the steel plate to determine whether the cutting precision of the steel plate meets the requirements. The operator does not need to frequently walk in the complex environment to track and verify the size of the steel plate, the steel plate number, the laser cutting precision and other issues, thereby reducing the labor intensity, improving the operation efficiency and the cutting precision, and improving the post safety factor.

[0025] In addition to the above embodiments, the application can have other implementation manners; any technical scheme formed by equivalent replacement or equivalent transformation falls within the protection scope required by the application.
