Detailed Description
Referring to fig. 1, the method for controlling a carving center through a key according to the present invention includes the following steps:
s1, checking whether the engraving center XYZ returns to the reference point;
firstly, selecting a 'back reference point' mode on an MCP panel of a carving center, then clicking 'ALL' to express that the reference point returning operation is carried out on the XYZ three axes, and after waiting for the XYZ three axes to return to a mechanical original point position, lighting a three-color yellow lamp to express that the XYZ back reference point is finished. If the point of reference is not returned, the carving center can not work, and the carving center gives an alarm and prompts after the on-line key is pressed. The solution is as follows: pressing the RESET button to clear the alarm, returning to the reference point according to the method, and connecting the device again.
S2, checking whether the tool magazine returns to zero or not, and carrying out normal tool changing after the tool magazine returns to zero;
firstly, selecting a 'return reference point' mode on an MCP panel of a carving center, then clicking 'tool magazine return to zero' to indicate that a servo motor of the tool magazine is returned to zero, lighting a 'tool magazine return to zero' button of the MCP panel of the carving center during the tool magazine return to zero to indicate that the button is returning to zero, and waiting for the key lamp to be turned off to indicate that the tool magazine has been returned to zero. If the tool magazine is not reset to zero, the engraving center cannot change tools, and the engraving center gives an alarm after the online key is pressed down. The solution is as follows: and pressing a RESET key to clear the alarm, returning the tool magazine to zero according to the method, and connecting the tool magazine again.
S3, checking whether the carving center is in an automatic mode or in a standby state;
the MDI mode and the program operation mode belong to the automatic mode, and one mode can be selected on the MCP panel; the states of the carving center are divided into 'running', 'standby' and 'alarm', and the state of stopping the running of the current program or clearing the current alarm can be in the standby state. If the laser is not in the automatic state or is not in the standby state, the carving center sends back an alarm prompt. The solution is as follows: and (5) pressing a RESET key to clear the alarm, and converting the state of the carving center according to the method.
S4, checking whether the robot is in the carving center or not, and if the robot is in the carving center, connecting the robot on line to ensure safety;
s5, when online, the XYZ axis of the carving center must be in a material changing safety position;
after the carving center is connected, the robot starts to change materials for the carving center, at the moment, the XYZ three axes must be in a material changing safety position, otherwise, the robot has the risk of collision. And selecting an MDI mode, loading an initialization program and executing, wherein the XY Z three axes are in a safe material changing position after the initialization program is completed. If the operation is not executed, the online is an alarm prompt of the engraving center. The solution is as follows: pressing the RESET button to clear the alarm, and executing the initialization program according to the method.
S6, safety is considered, the chuck is checked during material changing, and the chuck needs to be in an open in-place state;
and executing the initialization program, automatically opening the chuck in place, and giving an alarm to prompt if the chuck is not opened in place, so that the chuck cannot be connected.
S7, placing a warm air clamp on the chuck, opening the positioning surface for cleaning and blowing, and opening the automatic door in place;
if the chuck is not opened in place, the positioning surface is cleaned and blown, and the carving center gives an alarm; if the robot does not place the warming clamp for the first time, the photoelectric sensor can detect and control the automatic offline of the engraving center. The solution is as follows: and (4) executing an initialization program according to the method, and manually putting the hot air fixture into the hot air fixture.
S8, if the conditions are met, after the carving center on-line key is pressed for 3 seconds, the carving center is successfully on-line, the on-line key indicator lamp is turned on, and meanwhile, the operation interface key is locked;
and S9, after receiving the successful on-line signal of the engraving center, the upper controller starts to load and unload the engraving center, and the engraving center automatically starts processing.
All keys are locked after on-line
Considering the safety factor, the realization method is that corresponding conditions are added in the software PLC program segment of the control key, when the online state is realized, the conditions are not satisfied, and the key is invalid.
For example, the program controls "jog gear selection", where K172.0 is an on-line flag, and when K172.0 is set, neither of the keys X33.6 and X35.2 can act on R12.4, i.e., the key is locked.
The automatic off-line processing is carried out when the fault occurs, the normal processing of other engraving centers is not influenced, and the on-line processing can be carried out again after the problem is solved;
referring to fig. 2, in the on-line processing of the engraving center, when a failure or abnormality occurs, the engraving center is automatically off-line, then is manually processed, and is processed again on-line.
For example, the liquid level of the cutting fluid in the processing of the engraving center is lower than the normal processing liquid level, the engraving center is automatically off-line and gives an alarm to prompt manual liquid adding, and the manual liquid adding is completed and then the machine is connected again.
The realization method is to program the carving center software PLC and realize the function through the logic operation of variables.
And (3) performing online and offline operation on the equipment of the engraving center, and after the equipment is maintained or is used independently, connecting the engraving center again online to perform automatic loading and unloading processing.
At any moment, when a certain carving center is needed to be used independently or maintained, the off-line key can be pressed for 3 seconds manually, so that the off-line can be realized, all keys are unlocked at the moment, and the system cannot carry out loading and unloading on the off-line carving center.
When the carving center is in an online state, the carving center is divided into two states, namely processing or material changing.
When changing materials:
1. and pressing an off-line key, and stopping feeding the carving center by the robot.
2. Directly maintained or used independently.
Processing:
1. the offline button is pressed.
2. After the current processing is finished, the workpiece is maintained or used independently; or stopping the current processing and directly using.
The above-mentioned contents are only for illustrating the technical idea of the present invention, and the protection scope of the present invention is not limited thereby, and any modification made on the basis of the technical idea of the present invention falls within the protection scope of the claims of the present invention.
