Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
Referring to fig. 2, fig. 2 is a flowchart illustrating an embodiment of a method for detecting repetition precision according to an embodiment of the present invention, and for convenience of description, only a portion related to the embodiment of the present invention is shown. The repetition precision detection method can be executed by a computer device, and the computer device can be but is not limited to an industrial personal computer and other devices, and specifically, the repetition precision detection method comprises the following steps:
s101, when the linear module to be detected 20 moves back and forth between the initial position and the target position for multiple times, the actual position of the linear module to be detected 20, which is detected by the laser detector 10 when the linear module to be detected 20 moves to the target position each time, is obtained.
Specifically, the laser detector 10 is connected with a computer device to establish TCP communication, the laser detector 10 may be installed on one side (as shown in fig. 1) or other position of the linear module 20 to be detected, and the light emitting direction of the laser detector 10 is perpendicular to the moving direction of the linear module 20 to be detected (as shown in fig. 1) or on the same straight line. For example, the laser detector 10 may be a laser displacement sensor, such as a german west gram (SICK) model OD5000-C30T05 laser displacement sensor.
When repeated precision measurement is performed, the linear module 20 to be measured can be controlled to move back and forth for multiple times between the initial position and the target position, wherein when the light emitting direction of the laser detector 10 is perpendicular to the moving direction of the linear module 20 to be measured, the connecting line between the target position and the laser detector 10 is perpendicular to the moving direction, and when the light emitting direction and the moving direction of the laser detector 10 are on the same straight line, the target position coincides with the laser detector 10 or approaches the laser detector 10.
And acquiring the actual position of the linear module to be detected 20 detected by the laser detector 10 when the linear module to be detected 20 moves to the target position each time. It should be noted that, because of the problems of the precision of the movement of the linear module to be measured 20, and the like, when the linear module to be measured 20 is controlled to move to the target position, the actual position of the linear module to be measured 20 may have an error with the target position, and therefore, in this step, the actual position of the linear module to be measured 20 detected by the laser detector 10 is obtained, and the actual position can be used as reference data for determining the repeatability precision of the linear module to be measured 20.
And S102, calculating a position average value according to a plurality of actual positions measured by a plurality of times of reciprocating movement.
That is to say, in the process that the to-be-measured straight line module 20 moves to the target position repeatedly, the actual position of each time when the to-be-measured straight line module moves to the target position is collected, and then data of a plurality of actual positions are obtained, and then the data of the actual positions are subjected to average value calculation, so that the average value of the actual positions of the to-be-measured straight line module 20 is obtained.
S103, calculating actual repetition precision according to the position average value, and judging whether the actual repetition precision meets a preset requirement.
The actual position of the motion of the linear module 20 to be measured is related to the motion accuracy of the linear module 20 to be measured, and the average value of the actual positions of the multiple motions can reflect the actual repetition accuracy, so that the actual repetition accuracy can be calculated according to the average value of the actual positions of the multiple motions, and whether the actual repetition accuracy meets the preset requirement or not can be conveniently judged.
According to the repeated precision detection method provided by the embodiment of the invention, the laser detector 10 is used for directly measuring the moving data of the linear module 20 to be detected, the data can be measured without communicating with automation equipment, and the detection method can be executed by starting the single software installed on the industrial control display all-in-one machine, so that the repeated precision detection aim is realized, the detection efficiency is high, and the detection result is accurate and reliable. In addition, the method is suitable for various automatic devices, independent software development is not needed, and the compatibility is high.
Referring to fig. 3 to 4, in some embodiments of the present invention, step S103 is preceded by:
s201, circularly executing the steps before the actual repeated precision is calculated according to the position average value to obtain a plurality of position average values.
S202, determining the maximum value and the minimum value in the position average values, and calculating the difference value between the maximum value and the minimum value.
That is, in the embodiment, by repeatedly executing the steps S101 to S102 a plurality of times, each time the steps S101 to S102 are executed, a position average value can be obtained, and as described above, because of the repeated precision of the movement of the linear module to be measured 20, the position average values obtained each time are not necessarily equal. After obtaining a plurality of position average values, the maximum position average value (namely, the maximum value) and the minimum position average value (namely, the minimum value) are determined from the position average values, and then the difference value between the maximum value and the minimum value is calculated.
Correspondingly, step S103 includes:
and S301, calculating actual repetition precision according to the difference between the maximum value and the minimum value.
S302, calculating a deviation amplitude value between the actual repetition precision and the standard repetition precision, and judging whether the deviation amplitude value is in a preset deviation range.
That is, the difference between the maximum value and the minimum value may be used as a basis for determining the actual repetition accuracy, and a larger difference indicates a lower repetition accuracy, and a smaller difference indicates a higher repetition accuracy. And comparing the actual repetition precision with the standard repetition precision to obtain a deviation amplitude value, wherein the standard repetition precision value is a standard parameter and can be input into the computer equipment in advance, so that whether the deviation amplitude value is within a preset deviation range is judged according to the size of the deviation amplitude value, and whether the actual repetition precision meets a preset requirement can be accurately judged.
In an embodiment of the present invention, the repetition accuracy detecting method further includes:
and uploading the actual position, the position average value, the difference value between the maximum value and the minimum value, the actual repetition precision and the deviation amplitude value between the actual repetition precision and the standard repetition precision to a server. That is, the computer device communicates with the server, uploads the data in the repeated precision detection process to the server, and stores the data through the server, so as to manage the repeated precision detection of the automation device.
Referring to fig. 5, in one embodiment of the present invention, step S101 includes:
s401, monitoring data change of the laser detector 10 by adopting a recursive algorithm.
S402, when the data detected by the laser detector 10 reach a peak value and are kept unchanged within a preset time, acquiring the data of the laser detector 10 to determine the actual position of the to-be-detected straight line module 20.
In the process of moving the to-be-detected linear module 20 from the initial position to the target position, since the distance between the to-be-detected linear module 20 and the laser detector 10 is closer and closer, the more light rays reflected back by the to-be-detected linear module 20 are detected by the laser detector, so that the data detected by the laser detector is gradually increased from a smaller value, and when the to-be-detected linear module 20 reaches the target position, the to-be-detected linear module 20 is kept still, and then the data detected by the laser detector reaches the peak value and is kept unchanged.
Therefore, when the data detected by the laser detector 10 is at the peak value and remains unchanged within the preset time, it indicates that the linear module 20 to be detected reaches the target position, and the actual position of the linear module 20 to be detected can be determined by collecting the data of the laser detector 10 at the moment. In this embodiment, by monitoring the data change of the laser detector 10 and acquiring the data of the laser detector 10 when the data detected by the laser detector 10 reaches a peak value and remains unchanged for a predetermined time, the actual position of the linear module 20 to be detected can be accurately and reliably detected, and the repeated precision detection result is ensured to be more accurate and reliable.
In one embodiment of the present invention, step S101 is preceded by:
and acquiring the position of the laser detector 10, and determining the target position according to the position of the laser detector 10. Specifically, after the state of the laser detector 10 is detected by starting a thread on the computer device, the computer device and the laser detector 10 perform TCP communication through a preset IP address and a preset port number to acquire an initial position of the laser detector 10, and record the initial position into a program memory.
Since the connection line between the laser detector 10 and the target position is perpendicular to or on the same straight line as the moving direction of the linear module to be detected 20, the X-axis or Y-axis coordinate of the laser detector 10 is the same as the X-axis or Y-axis coordinate of the target position, for example, the laser detector 10 is disposed at one side of the linear module to be detected 20, and the moving direction of the linear module to be detected 20 is along the Y-axis, the Y-axis coordinate of the laser detector 10 is the same as the Y-axis coordinate of the target position, so that the Y-axis coordinate of the target position can be determined.
In this embodiment, by acquiring the position of the laser detector 10, it is convenient to determine the target position where the linear module 20 to be detected moves.
