Description

Technical Field

[0001] The present application relates to the technical field of building material testing, and in particular to a method, a system, a storage medium and an intelligent terminal for measuring the thickness of a building material coating. Background Art

[0002] In order to endow some building materials with better corrosion resistance, surface coating treatment is usually carried out on building materials such as steel and aluminum. During the process of foreign trade of building materials, there are certain requirement standards for the coating thickness on the surface of building materials.

[0003] In the prior art, the detection of coating thickness is generally realized by using a coating thickness gauge. The existing coating thickness gauge has a probe for detecting the coating thickness. When detecting the coating thickness, usually a staff member manually holds the probe and presses the probe against the detection point on the surface of the workpiece for detection. And during the detection process, it is necessary to keep the probe perpendicular to the measurement surface to make the detection result more accurate. When the overall length of the workpiece is relatively long, it is necessary to perform multi-point detection on the workpiece to improve the accuracy of the workpiece thickness detection.

[0004] Regarding the above related technologies, the inventor believes that when the number of workpieces to be detected is large, the staff may get fatigued after detecting a certain number. At this time, when the staff manually grasps the probe for thickness detection, there may be a situation where the probe is not perpendicular to the measurement surface, which is likely to cause detection errors and result in a low detection accuracy rate, and there is still room for improvement. Summary of the Invention

[0005] In order to improve the detection accuracy rate of the coating thickness of workpieces, the present application provides a coating thickness detection method.

[0006] In a first aspect, the present application provides a coating thickness measurement method, adopting the following technical solution:

[0007] A coating thickness measurement method includes:

[0008] Obtaining the length information and width information of a workpiece to be measured;

[0009] Performing matching analysis according to the length information and quantity information stored in a preset quantity database to determine the detection quantity information corresponding to the length information;

[0010] Dividing the workpiece to be measured evenly according to the detection quantity information and the length information to determine the lateral position information of the detection points in the length direction of the workpiece;

[0011] Determining the detection path information according to the width information on the workpiece to be measured, and determining the detection position information of the detection points according to the lateral position information and the detection path information;

[0012] Control the preset detection device to move on the path corresponding to the detection path information and perform a detection operation at the position corresponding to the detection position information, so as to obtain the coating thickness information at the detection point.

[0013] By adopting the above technical solution, the relatively long workpiece to be measured is evenly divided and detected, making the detection result relatively more accurate. At the same time, compared with manual detection, it is not easy to have the situation that the probe on the detection device is not perpendicular to the measurement surface, and the detection accuracy is high.

[0014] Optionally, before controlling the detection device to move for operation, the coating thickness detection method further includes:

[0015] Obtain the first included angle information between the detection device and the preset calibration plane;

[0016] Judge whether the included angle corresponding to the first included angle information is consistent with the preset detection included angle;

[0017] If the included angle corresponding to the first included angle information is consistent with the detection included angle, output a normal signal and control the detection device to perform a detection operation on the detection point;

[0018] If the included angle corresponding to the first included angle information is inconsistent with the detection included angle, obtain the second included angle information between the detection device and the preset vertical plane;

[0019] Calculate according to the preset device length value, the first included angle information, the second included angle information and the initial coordinate information of the preset clamping point to determine the end point position information;

[0020] Determine the target position information according to the coordinate position corresponding to the initial coordinate information and the device length value;

[0021] Determine the movement direction information according to the end point position information and the target position information;

[0022] Calculate according to the first included angle information to determine the complementary angle information;

[0023] Control the detection device to rotate by the angle value corresponding to the complementary angle information around the clamping point in the direction corresponding to the movement direction information.

[0024] By adopting the above technical solution, when controlling the detection device to move to the position corresponding to the detection point for detection, first detect the perpendicular relationship between the detection device and the workpiece to be measured, so as to reduce the probability that the detection result is inaccurate due to the non-perpendicular situation between the detection device and the workpiece to be measured.

[0025] Optionally, during the movement operation of the detection device, the coating thickness detection method further includes:

[0026] Control the detection device to rise to a preset moving height and move along the detection path to a position above the detection point;

[0027] When the detection device moves to a position above the detection point, obtain the distance information between the detection device and the calibration plane;

[0028] Judge whether the distance corresponding to the distance information is consistent with the preset standard distance;

[0029] If the distance corresponding to the distance information is consistent with the standard distance, control the detection device to move downward to detect the current detection point, and after the detection is completed, control the detection device to rise to the moving height and continue to move along the detection path;

[0030] If the distance corresponding to the distance information is inconsistent with the standard distance, define the detection point as a non-detection point, and control the detection device to move to the next detection point for detection.

[0031] By adopting the above technical solution, control the detection device to rise to a certain height after detecting each detection point and then move towards the next detection point, so that the detection device is not prone to relative friction when detecting multiple detection points on the workpiece to be measured. When the distance corresponding to the distance information is inconsistent with the preset standard distance, it indicates that the detection point is not a plane, and mark the detection point as a non-detection point to reduce the probability of inaccurate detection results.

[0032] Optionally, when a non-detection point is detected, before controlling the detection device to move to the next detection point for detection, the method for coating thickness detection further includes:

[0033] Perform matching analysis according to the workpiece type information, length information, and width information stored in the preset type database to determine the workpiece type information corresponding to the length information and width information;

[0034] Perform matching analysis according to the exemption position information and workpiece type information stored in the preset position database to determine the exemption position information corresponding to the workpiece type information;

[0035] Judge whether the exemption position corresponding to the exemption position information is consistent with the non-detection point;

[0036] If the exemption position corresponding to the exemption position information is consistent with the non-detection point, control the detection device to move to the next detection point for detection;

[0037] If the exemption position corresponding to the exemption position information is inconsistent with the non-detection point, define the workpiece to be measured as an abnormal workpiece and stop the detection.

[0038] By adopting the above technical solution, the position information of the workpiece type is matched and analyzed with the inspection-free position information in the position database to determine whether the position of the non-inspection point belongs to the inspection-free position on the workpiece to be measured. When the position of the non-inspection point is inconsistent with the inspection-free position, it indicates that there is an abnormal situation on the surface of the workpiece to be measured, and the workpiece is unqualified. At this time, it is not necessary to further detect the workpiece, reducing the detection time loss of the unqualified workpiece and improving the detection work efficiency.

[0039] Optionally, after the current inspection point is detected, the control method of the inspection device includes:

[0040] Judge whether there is a position corresponding to the inspection-free position information between the position of the current inspection point and the position of the next adjacent inspection point;

[0041] If there is no position corresponding to the inspection-free position information between the position of the current inspection point and the position of the next adjacent inspection point, control the inspection device to rise to the moving height and move along the inspection path to the next inspection point;

[0042] If there is a position corresponding to the inspection-free position information between the position of the current inspection point and the position of the next adjacent inspection point, obtain the characteristic height information at the position corresponding to the inspection-free position information;

[0043] According to the preset sorting rule, determine the characteristic height information with the largest corresponding height value among all the characteristic height information, and define this characteristic height information as the upper limit height information;

[0044] Determine the maximum height between the height value corresponding to the upper limit height information and the moving height, and control the inspection device to rise to the maximum height so that the inspection device moves along the inspection path to the next adjacent inspection point.

[0045] By adopting the above technical solution, before the inspection device moves to the next inspection point, it is judged whether there is a convex feature at the position of the inspection-free point. When there is a convex feature and there is more than one convex feature, sort the heights corresponding to all the convex features, control the inspection device to move to the upper limit height position with the largest height value and then move to the next inspection point for detection, thereby reducing the probability of the inspection device being blocked and collided during the movement along the inspection path, and playing a role in protecting the inspection device.

[0046] Optionally, after the inspection device finishes rising and before moving to the next adjacent inspection point, the control method of the inspection device further includes:

[0047] Obtain the horizontal spacing information in the detection path direction of the inspection device;

[0048] Calculate according to the lateral position information of the current inspection point and the lateral position information of the next adjacent inspection point to determine the moving distance information;

[0049] Determine whether the distance value corresponding to the horizontal spacing information is less than the distance value corresponding to the moving distance information;

[0050] If the distance value corresponding to the horizontal spacing information is not less than the distance value corresponding to the moving distance information, output an unobstructed signal and control the detection device to move along the detection path to the next adjacent detection point for detection;

[0051] If the distance value corresponding to the horizontal spacing information is less than the distance value corresponding to the moving distance information, control the detection device to rise until an unobstructed signal is output.

[0052] By adopting the above technical solution, compare the distance values corresponding to the horizontal spacing information and the moving distance information to determine whether a collision will occur when the detection device moves along the detection path to the next adjacent detection point, and control the detection device to rise to a height where it will not be blocked before moving, reducing the probability of the detection device being collided during the detection process.

[0053] Optionally, when the distance value corresponding to the horizontal spacing information is less than the distance value corresponding to the moving distance information, the control method of the detection device further includes:

[0054] Determine the characteristic position information according to the lateral position information of the current detection point and the horizontal spacing information;

[0055] Determine whether the position corresponding to the characteristic position information is the same as the position corresponding to the exemption inspection position information;

[0056] If the position corresponding to the characteristic position information is the same as the position corresponding to the exemption inspection position information, control the detection device to rise until an unobstructed signal is output;

[0057] If the position corresponding to the characteristic position information is not the same as the position corresponding to the exemption inspection position information, define the workpiece to be measured as an abnormal workpiece and stop the detection.

[0058] By adopting the above technical solution, judge from the position corresponding to the characteristic position information and the position corresponding to the exemption inspection position information to determine whether the characteristic at the exemption inspection position information is a normal characteristic on the detected workpiece, so as to further screen the abnormal workpiece and improve the detection efficiency of the normal workpiece.

[0059] In a second aspect, the present application provides a building material coating thickness measurement system, adopting the following technical solution:

[0060] A building material coating thickness measurement system, including:

[0061] A processing module, connected to the acquisition module, for storing and processing information;

[0062] The processing module performs matching analysis based on the length information and quantity information stored in the preset quantity database to determine the detection quantity information corresponding to the length information;

[0063] The processing module evenly divides the workpiece to be measured according to the detection quantity information and the length information to determine the lateral position information of the detection points in the length direction of the workpiece;

[0064] The processing module determines the detection path information based on the width information on the workpiece to be measured, and determines the detection position information of the detection points based on the lateral position information and the detection path information;

[0065] The processing module controls the preset detection device to move on the path corresponding to the detection path information and perform detection operations at the position corresponding to the detection position information to obtain the coating thickness information at the detection points.

[0066] By adopting the above technical solution, the acquisition module acquires the length and width information of the workpiece to be measured, determines the detection point quantity information, and the processing module determines the positions of the detection points according to the detection point quantity information, and controls the detection device to be perpendicular to the plane where the detection points are located, so as to reduce the probability that the detection result is inaccurate due to the non-perpendicular situation between the detection device and the workpiece to be measured.

[0067] In a third aspect, the present application provides an intelligent terminal, adopting the following technical solution:

[0068] An intelligent terminal includes a memory and a processor, and a computer program capable of being loaded and executed by the processor for any of the above building material coating thickness measurement methods is stored on the memory.

[0069] By adopting the above technical solution, through the use of the intelligent terminal, the workpiece to be measured with a long length is evenly divided and detected, so that the detection result is relatively more accurate. At the same time, compared with manual detection, it is not easy to have the situation that the probe on the detection device is not perpendicular to the measurement surface, and the detection accuracy is high.

[0070] In a fourth aspect, the present application provides a computer storage medium, which can store corresponding programs and has the characteristic of reducing the probability that the detection device and the workpiece to be measured are not perpendicular to each other when the detection device detects the workpiece to be measured. The following technical solution is adopted:

[0071] A computer-readable storage medium stores a computer program capable of being loaded and executed by the processor for any of the above building material coating thickness measurement methods.

[0072] By adopting the above technical solution, there is a computer program in the storage medium that can be loaded and executed by the processor for any of the above building material coating thickness measurement methods. The method evenly divides and detects a workpiece with a relatively long length, making the detection result relatively more accurate. At the same time, compared with manual detection, it is not easy to have the situation where the probe on the detection device is not perpendicular to the measurement surface, and the detection accuracy is high.

[0073] In summary, the present application includes at least one of the following beneficial technical effects:

[0074] 1. By using the detection device to detect the evenly divided detection points on the workpiece to be measured, while making the detection result relatively more accurate, compared with manual detection, it is not easy to have the situation where the probe is not perpendicular to the measurement surface, thereby further improving the detection accuracy of the workpiece to be measured;

[0075] 2. Detect the state of the detection device before detection to adjust the situation where the angle between the detection device and the calibration plane does not meet the perpendicularity requirement, so that the detection device remains perpendicular to the calibration plane during the detection operation to improve the detection accuracy;

[0076] 3. Judge between the position corresponding to the characteristic position information and the position corresponding to the non-detection position information to determine whether the characteristic at the non-detection position information is a normal characteristic on the detection workpiece, so as to further screen abnormal workpieces and improve the detection efficiency of normal workpieces.

[0086] In order to make the purpose, technical solutions and advantages of the present application clearer and more understandable, the following will further describe the present application in detail in conjunction with the attached Figures 1-10 drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0087] The embodiments of the present invention will be further described in detail below with reference to the drawings of the specification.

[0088] The embodiment of the present application discloses a method for measuring the thickness of a building material coating. First, obtain the length information and width information of a workpiece to be measured, perform matching analysis in a preset number database according to the length information and width information of the workpiece to be measured to obtain the detection number information corresponding to the length information, then determine the horizontal position information of the detection points on the workpiece to be measured according to the detection number information and the length information, determine the detection path information according to the width information, and determine the detection position information of the detection points according to the horizontal position information and the detection path information. Finally, control the detection device to move to each detection point for detection. Compared with manual detection, it is not easy to have the situation that the detection device is not perpendicular to the workpiece to be measured, so as to improve the detection accuracy and detection efficiency at the same time.

[0089] Refer to Figure 1 , the process of the method for measuring the thickness of a building material coating includes the following steps:

[0090] Step S100: Obtain the length information and width information of the workpiece to be measured;

[0091] The workpiece to be measured is a building material workpiece after surface coating processing. The length corresponding to the length information is the distance along the length direction of the measurement surface of the workpiece to be measured, and the width corresponding to the width information is the distance along the width direction of the measurement surface of the workpiece to be measured. The length direction and width direction of the workpiece to be measured are set by the staff and will not be elaborated.

[0092] Step S101: Perform matching analysis according to the length information and quantity information stored in the preset number database to determine the detection number information corresponding to the length information;

[0093] The measurement surfaces of the workpieces to be measured have different lengths and widths. By collecting the length information and width information corresponding to the measurement surfaces of different workpieces, a quantity database is established. The quantity corresponding to the detected quantity information is the number of detection points on the workpiece to be measured. By inputting the length information and width information of the workpiece to be measured into the database, the detected quantity information matching the workpiece to be measured can be obtained from the quantity database. The method for establishing the database is a common technical means for those skilled in the art and will not be described in detail.

[0094] Step S102: Divide the workpiece to be measured evenly according to the detected quantity information and the length information to determine the lateral position information of the detection points in the length direction of the workpiece;

[0095] The lateral position corresponding to the lateral position information is the lateral position of each detection point in the detected quantity information on the workpiece to be measured. The direction corresponding to the lateral position is the length direction of the workpiece to be measured. The lateral position is obtained by dividing the length corresponding to the length information by the number of detection points. Multiple detection points are arranged collinearly in the length direction.

[0096] Step S103: Determine the detection path information on the workpiece to be measured according to the width information, and determine the detection position information of the detection points according to the lateral position information and the detection path information;

[0097] The detection path corresponding to the detection path information is the straight-line position where multiple detection points are located. The direction of the detection path is the extension direction from one end to the other end in the length direction of the workpiece. The position of the straight line is determined by the width of the workpiece to be measured. The determination method is to divide the width of the workpiece to be measured evenly. The detection point position information is the specific position of multiple detection points on the measurement surface, which is determined by the lateral position of the detection points in the length direction and the detection path in the width direction.

[0098] Step S104: Control the preset detection device to move on the path corresponding to the detection path information and perform detection operations at the positions corresponding to the detection position information to obtain the coating thickness information at the detection points.

[0099] The detection device includes a clamping manipulator and a coating thickness gauge. The coating thickness gauge has a detection probe. The detection probe is arranged in a long strip shape and is clamped on the manipulator. When detecting the workpiece to be measured, the workpiece to be measured is placed on the detection workbench. The manipulator is slidably arranged on the detection workbench and slides along the detection path direction, so that the detection probe is perpendicular to the measurement surface while performing detection operations on the detection points. The coating thickness information is the coating thickness value obtained when the coating thickness gauge performs detection operations.

[0100] Refer to Figure 2 , before controlling the detection device to move and operate, the coating thickness detection method further includes:

[0101] Step S200: Obtain the first included angle information between the detection device and the preset calibration plane;

[0102] The calibration plane is the measurement surface on the workpiece to be measured. The included angle corresponding to the first included angle information is the included angle formed between the calibration plane and the axis of the detection probe. The method for determining the included angle corresponding to the first included angle information is as follows: First, determine the position of the clamping point where the clamping manipulator clamps on the probe. Use the clamping point as the coordinate origin for spatial modeling to determine the coordinate position information of the clamping point. The method of spatial modeling is a common technical means for those skilled in the art and will not be described in detail. Before modeling, obtain the length and dimension information of the detection probe through the instruction manual of the coating thickness gauge. Determine the projected length value of the detection probe on the horizontal plane through modeling. Extend and intersect the axis of the detection probe and the axis on the projection plane. The included angle formed between the axis of the detection probe and the axis on the projection plane is the included angle corresponding to the first included angle information.

[0103] Step S201: Determine whether the included angle corresponding to the first included angle information is consistent with the preset detection included angle;

[0104] The angle situation corresponding to the detection included angle is that the axis of the probe is perpendicular to the calibration plane. The purpose of the determination is to know that before detecting the detection point, the detection probe is perpendicular to the calibration plane, so that when the detection probe detects the detection point, the obtained detection result is relatively accurate.

[0105] Step S202: If the included angle corresponding to the first included angle information is consistent with the detection included angle, output a normal signal and control the detection device to perform a detection operation on the detection point;

[0106] If the included angle corresponding to the first included angle information is consistent with the detection included angle, it means that the probe is in a state perpendicular to the calibration plane. At this time, output a normal signal for identification, so that when the normal signal is output, the manipulator can clamp the detection probe to perform a detection operation on the detection point.

[0107] Step S203: If the included angle corresponding to the first included angle information is inconsistent with the detection included angle, obtain the second included angle information between the detection device and the preset vertical plane;

[0108] If the included angle corresponding to the first included angle information is inconsistent with the detected included angle, it indicates that the axis of the probe is inclined with respect to the calibration plane, and the probe needs to be adjusted. At this time, the second included angle information is obtained to facilitate subsequent adjustment of the probe according to the second included angle information. The vertical plane is a plane perpendicular to the calibration plane. The method for determining the included angle corresponding to the second included angle information is as follows: project the axis of the detection probe onto the vertical plane, and then extend the axis on the projection plane and the axis of the detection probe until they intersect. At this time, the included angle formed by the axis on the projection plane and the axis of the detection probe is the included angle corresponding to the second included angle information.

[0109] Step S204: Calculate based on the preset device length value, the first included angle information, the second included angle information, and the initial coordinate information of the preset clamping point to determine the end point position information;

[0110] The initial coordinate corresponding to the initial coordinate information is the coordinate of the clamping point where the clamping manipulator clamps on the detection probe. The clamping point coordinate is determined in the above step S200. The end point position corresponding to the end point position information is the coordinate of the end of the detection probe away from the clamping point position on its own axis. The calculation method of the coordinate position of the end point position information is as follows: Given the vertical plane, the calibration plane, the length value, the first included angle, and the second included angle, calculate through trigonometric relations and trigonometric formulas to obtain the relative position coordinate between the end of the probe away from the clamping point and the origin coordinate.

[0111] Step S205: Determine the target position information based on the coordinate position corresponding to the initial coordinate information and the device length value;

[0112] The coordinate position corresponding to the target position information is the target coordinate position to which the end point coordinate corresponding to the end point position information needs to move when the probe rotates to a state perpendicular to the calibration plane. The calculation method of the coordinate position corresponding to the target position information is as follows: Taking the coordinate origin as the reference point, on the premise that the x-axis and y-axis remain unchanged, the z-axis coordinate position obtained by subtracting the length corresponding to the length value in the z-axis direction is the coordinate position corresponding to the target position information. The purpose of calculating the target position information is to facilitate subsequent calls.

[0113] Step S206: Determine the movement direction information based on the end point position information and the target position information;

[0114] The movement direction corresponding to the movement direction information is: taking the coordinate position corresponding to the end point position information as the starting point and the coordinate position corresponding to the target position information as the end point, the direction formed between the two points and pointing from the starting point to the end point.

[0115] Step S207: Calculate based on the first included angle information to determine the complementary angle information;

[0116] The complementary included angle corresponding to the complementary angle information is the complementary angle between the axis of the probe itself and the standard plane. The calculation method of the complementary included angle is: subtract the angle corresponding to the first included angle information from a right angle. The determination of the complementary angle information is for the convenience of subsequent calls.

[0117] Step S208: Control the detection device to rotate by the angle value corresponding to the complementary angle information in the direction corresponding to the movement direction information with the clamping point as the rotation point.

[0118] By controlling the detection device to rotate by the angle value corresponding to the complementary included angle information along the clamping point, the probe is adjusted to a state perpendicular to the calibration plane, so that when detecting the detection point subsequently, it is not easy to have the situation that the detection result is inaccurate due to the probe not being perpendicular to the calibration plane.

[0119] Refer to Figure 3 , during the movement operation of the detection device, the coating thickness detection method further includes:

[0120] Step S300: Control the detection device to rise to a preset movement height and move along the detection path to the position above the detection point;

[0121] The height corresponding to the movement height is the height higher than the calibration plane. The value of the movement height is set by the staff according to the actual situation and will not be elaborated. The rise of the detection device is achieved by the telescopic movement of the clamping manipulator in the vertical direction. The purpose of controlling the detection device to rise to the movement height is to reduce the probability that the probe on the detection device still abuts against the workpiece surface and causes wear when the detection device moves to the next adjacent detection point after detecting a detection point. After the detection device finishes detecting the current detection point, it rises to the movement height and moves at the movement height towards the position directly above the next detection point until it stops moving after completing the detection operations of all detection points.

[0122] Step S301: Obtain the separation distance information between the detection device and the calibration plane when the detection device moves to the position above the detection point;

[0123] The separation distance corresponding to the separation distance information is the distance between the probe and the calibration plane. The acquisition of the separation distance information is for the convenience of subsequent calls. The separation distance information can be measured by pre-installing an infrared rangefinder on the clamping manipulator.

[0124] Step S302: Determine whether the distance corresponding to the separation distance information is consistent with the preset standard distance;

[0125] The standard distance is the minimum distance between the probe on the detection device and the calibration plane. The value of the standard distance is set by the staff according to the actual situation and will not be elaborated. The purpose of the judgment is to know whether there are protrusions or grooves on the plane where the detection point is located, so as to facilitate the subsequent processing of the situations of protrusions or grooves.

[0126] Step S303: If the distance corresponding to the separated distance information is consistent with the standard distance, control the detection device to move downward to detect the current detection point, and after the detection is completed, control the detection device to rise to the moving height and continue to move along the detection path;

[0127] If the distance corresponding to the separated distance information is consistent with the standard distance, it indicates that there are no protrusions or grooves on the plane where the detection point is located. At this time, control the detection device to move downward to the surface of the workpiece to be measured to perform the detection operation on the detection point. After the detection is completed, control the detection device to rise to the moving height and continue to move to the next adjacent detection point for detection.

[0128] Step S304: If the distance corresponding to the separated distance information is inconsistent with the standard distance, define this detection point as a non-detection point and control the detection device to move to the next detection point for detection.

[0129] If the distance corresponding to the separated distance information is inconsistent with the standard distance, it indicates that there are grooves or protrusions on the plane where this detection point is located. At this time, define this detection point as a non-detection point and mark it, so that when the detection device recognizes the mark of the non-detection point, it will not detect this detection point, so as to reduce the probability of inaccurate detection results caused by detecting this detection point.

[0130] Refer to Figure 4 , when a non-detection point is detected, before controlling the detection device to move to the next detection point for detection, the method for detecting the coating thickness further includes:

[0131] Step S400: Perform matching analysis according to the workpiece type information, length information, and width information stored in the preset type database to determine the workpiece type information corresponding to the length information and width information;

[0132] The workpiece types corresponding to the workpiece type information are different, and the length information and width information of the measurement surfaces on different workpiece types are different. By storing the types of different building materials workpieces and the corresponding length information and width information in the database and defining this database as the type database, the length information and width information of the corresponding type of workpiece can be obtained by inputting the type information into the type database. The establishment of the database is a common technical means within the scope of those skilled in the art and will not be elaborated. The determination of the workpiece type information is for the convenience of subsequent calling.

[0133] Step S401: Perform matching analysis based on the non-inspection position information and workpiece type information stored in the preset position database to determine the non-inspection position information corresponding to the workpiece type information;

[0134] The non-inspection position corresponding to the non-inspection position information is the position of the detection point where there is a protrusion or groove on the plane where the detection point of the workpiece to be measured is located. The protrusion and groove at this detection point are normal structures on the workpiece to be measured. When the detection points are distributed on the non-inspection positions, it is not necessary to detect the detection points on the non-inspection positions. Different workpiece types have different non-inspection position information. There is information about the non-inspection point positions on the drawings during workpiece production. By collecting the non-inspection point position information of different types of workpieces, a position database is established. Inputting the workpiece type information into the position database can obtain the non-inspection position information matching the workpiece type information. The method of establishing the database is a common technical means for those skilled in the art and will not be described in detail. The determination of the non-inspection position information is for the convenience of subsequent calls.

[0135] Step S402: Determine whether the non-inspection position corresponding to the non-inspection position information is consistent with the non-detection point;

[0136] The purpose of the determination is to know whether the non-detection point is truly in a position that does not need to be detected, so as to confirm the abnormal structure of the workpiece.

[0137] Step S403: If the non-inspection position corresponding to the non-inspection position information is consistent with the non-detection point, control the detection device to move to the next detection point for detection;

[0138] If the non-inspection position corresponding to the non-inspection position information is consistent with the non-detection point, it means that the non-detection point is on the structure of the workpiece with normal protrusions or grooves and does not need to be detected. At this time, control the detection device to move to the next adjacent detection point for detection operation.

[0139] Step S404: If the non-inspection position corresponding to the non-inspection position information is inconsistent with the non-detection point, define the workpiece to be measured as an abnormal workpiece and stop the detection.

[0140] If the non-inspection position corresponding to the non-inspection position information is inconsistent with the non-detection point, it means that the non-detection point is on the abnormal protrusion or groove structure of the workpiece, and the workpiece is an unqualified abnormal workpiece. Define the workpiece as an abnormal workpiece and mark it, so that when the detection device detects the abnormal workpiece mark, it stops detecting the workpiece.

[0141] Refer to Figure 5 , after the current detection point is detected, the control method of the detection device includes:

[0142] Step S500: Determine whether there is a position corresponding to the exemption position information between the position of the current detection point and the position of the next adjacent detection point;

[0143] The purpose of the determination is to find out whether the detection device will be hindered by obstacle collisions when moving to the next adjacent detection point at the moving height, so as to make subsequent responses. The position of the current detection point can be obtained by setting a position detection sensor on the detection device and can be obtained through the drawing information during workpiece production.

[0144] Step S501: If there is no position corresponding to the exemption position information between the position of the current detection point and the position of the next adjacent detection point, control the detection device to rise to the moving height and move along the detection path to the next detection point;

[0145] If there is no position corresponding to the exemption position information between the position of the previous detection point and the position of the next adjacent detection point, it means that the detection device will not be hindered or collided by the normal convex structure on the workpiece when moving along the detection path to the next adjacent detection point. At this time, control the detection device to move to the moving height and then move to the next detection point for detection operations.

[0146] Step S502: If there is a position corresponding to the exemption position information between the position of the current detection point and the position of the next adjacent detection point, obtain the feature height information at the position corresponding to the exemption position information;

[0147] If there is a position corresponding to the exemption position information between the position of the current detection point and the position of the next adjacent detection point, it means that there is a normal convex structure between the current detection point and the next adjacent detection point. At this time, when controlling the detection device to rise to the moving height and move towards the next detection point, there may be a situation where the detection device is collided by the normal convex. The height corresponding to the feature height information is the height of the convex feature at the exemption position. The height information of the convex feature at the exemption position can be obtained through the drawing of the building materials. The purpose of obtaining the feature height information at the position corresponding to the exemption position information is for subsequent calls.

[0148] Step S503: Determine the feature height information with the largest corresponding height value among all the feature height information according to the preset sorting rule, and define this feature height information as the upper limit height information;

[0149] The upper limit height corresponding to the upper limit height information is the height corresponding to the feature height information. The rule corresponding to the sorting rule is: first obtain the feature height information of the convex features at all exemption positions, and sort the height values corresponding to each feature height information from small to large in turn. After the sorting is completed, define the feature height information with the largest height value as the upper limit height information for subsequent calls to the upper limit height information.

[0150] Step S504: Determine the maximum height from the height value corresponding to the upper limit height information and the moving height, and control the detection device to rise to the maximum height so that the detection device moves along the detection path to the next adjacent detection point.

[0151] The purpose of determining the maximum height is to obtain the moving height at which the detection device will not collide during movement. The determination method is to compare the height corresponding to the upper limit height information with the moving height, and then control the detection device to move to the maximum height and move along the direction of the detection path to the next detection point, so that the detection device is not easily blocked during movement.

[0152] Refer to Figure 6 , after the detection device finishes rising and before moving to the next adjacent detection point, the control method of the detection device further includes:

[0153] Step S600: Obtain the horizontal spacing information in the direction of the detection path of the detection device;

[0154] The horizontal distance corresponding to the horizontal spacing information is the distance between the horizontal side wall of the probe on the detection device and the protruding feature at the next adjacent non-inspection position on the detection path. Determine the adjacent protruding structure corresponding to the non-inspection position information through the drawing during workpiece production, and calculate the minimum distance between the protruding structure and the side wall around the probe on the detection device. This distance is the horizontal distance corresponding to the horizontal spacing information. The determination of the horizontal spacing information is for convenient subsequent invocation.

[0155] Step S601: Calculate based on the lateral position information of the current detection point and the lateral position information of the next adjacent detection point to determine the moving distance information;

[0156] The distance corresponding to the moving distance information is the distance required for the detection device to move to the next adjacent detection point. The lateral position information of the current detection point and the position information of the next adjacent detection point can be obtained through the workpiece drawing.

[0157] Step S602: Determine whether the distance value corresponding to the horizontal spacing information is less than the distance value corresponding to the moving distance information;

[0158] The purpose of the determination is to know whether there is a position of the non-inspection point with a protruding feature during the movement of the detection device to the next adjacent detection point, so as to facilitate subsequent control of the movement of the detection device.

[0159] Step S603: If the distance value corresponding to the horizontal spacing information is not less than the distance value corresponding to the moving distance information, output an unobstructed signal, and control the detection device to move along the detection path to the next adjacent detection point for detection;

[0160] If the distance value corresponding to the horizontal spacing information is not less than the distance value corresponding to the movement distance information, it indicates that when the detection device moves to the next adjacent detection point, it will not be obstructed by the protruding feature corresponding to the exemption position information. At this time, an unobstructed signal is output and marked. When the detection device receives the unobstructed signal, it controls the movement to the next adjacent detection point for detection operations.

[0161] Step S604: If the distance value corresponding to the horizontal spacing information is less than the distance value corresponding to the movement distance information, control the detection device to rise until an unobstructed signal is output.

[0162] If the distance value corresponding to the horizontal spacing information is less than the distance value corresponding to the movement distance information, it indicates that there is an exemption position corresponding to the exemption position feature information between the detection device and the next adjacent detection point, and there is a protruding structure at this exemption position. This protruding structure will obstruct the detection device during the process of moving to the next adjacent detection point for detection. At this time, control the detection device to continue to rise until an unobstructed signal is output.

[0163] Refer to Figure 7 When the distance value corresponding to the horizontal spacing information is less than the distance value corresponding to the movement distance information, the control method of the detection device further includes:

[0164] Step S700: Determine the feature position information based on the lateral position information of the current detection point and the horizontal spacing information;

[0165] The position corresponding to the feature position information is the minimum distance between the current detection point and the adjacent protruding structure in the lateral direction corresponding to the lateral position information. The minimum distance can be obtained by referring to the distance between adjacent protruding structures marked on the production drawing of the workpiece. The protruding structure is a feature that should exist at the exemption position.

[0166] Step S701: Determine whether the position corresponding to the feature position information is consistent with the position corresponding to the exemption position information;

[0167] The purpose of the determination is to know whether the protruding feature at the exemption position is consistent with the position of the feature marked on the drawing, so as to further screen the workpieces with abnormal positions of the protruding structure during the processing.

[0168] Step S702: If the position corresponding to the feature position information is consistent with the position corresponding to the exemption position information, control the detection device to rise until an unobstructed signal is output;

[0169] If the position corresponding to the feature position information is consistent with the position corresponding to the exemption position information, it indicates that the protruding feature at the exemption position of the workpiece is consistent with the one marked on the drawing. At this time, there is no abnormal processing situation for the workpiece. Control the detection device to rise until an unobstructed signal is output, so that the detection device can move to the next detection point for detection operations.

[0170] Step S703: If the position corresponding to the feature position information is inconsistent with the position corresponding to the exemption position information, then define the workpiece to be measured as an abnormal workpiece and stop the detection.

[0171] If the position corresponding to the feature position information is inconsistent with the position corresponding to the exemption position information, it indicates that the protruding feature at the exemption position of the workpiece is inconsistent with that marked on the drawing, and there is an abnormal machining situation for the workpiece. At this time, define the workpiece as an abnormal workpiece and mark it, and control the detection device to stop detecting when an abnormal workpiece is detected.

[0172] Refer to Figure 8 and Figure 9 Before controlling the detection device to move downward, the control method of the detection device further includes:

[0173] Step S800: Obtain the obstacle area information of the current detection point and divide the projected area information when the detection device descends according to a preset division method;

[0174] The preset division method is to use the axis of the detection probe as the origin, and rotate 360° circumferentially with the radius of the detection probe. The circular area obtained by the division is the area corresponding to the projected area information. The area corresponding to the obstacle area information is the projected area on the horizontal plane of the normal protruding structure at the next adjacent non-detection point. The area projection plane of the obstacle area information can be obtained through the production drawing information of the workpiece.

[0175] Step S801: Determine whether there is a non-detection point in the projection area corresponding to the projected area information;

[0176] The purpose of the determination is to know whether there is an intersection area between the detection probe and the protruding structure at the non-detection point during the descent of the detection probe, so as to know whether the detection probe will come into contact with the protruding structure during the descent.

[0177] Step S802: If there is no non-detection point in the projection area corresponding to the projected area information, then control the detection device to descend to detect the detection point;

[0178] If there is no non-detection point in the projection area corresponding to the projected area information, it means that the detection device will not come into contact with the protruding structure at the adjacent non-detection point when descending to the detection point, so that the detection probe will not deflect due to contact, resulting in inaccurate detection results.

[0179] Step S803: If there is a non-detection point in the projection area corresponding to the projected area information, then determine whether the area corresponding to the obstacle area information intersects with the area corresponding to the projected area information;

[0180] If there are non-detection points in the projection area corresponding to the projection area information, it indicates that the detection probe may make relative contact with the probe on the non-detection point during the descending process, which may cause the detection probe to deflect and not be perpendicular to the calibration plane. At this time, by determining whether the area corresponding to the obstacle area information intersects with the area corresponding to the projection area information, the contact situation between the convex structure and the detection probe can be further known.

[0181] Step S804: If the area corresponding to the obstacle area information does not intersect with the area corresponding to the projection area information, control the detection device to descend to detect the detection point;

[0182] The area corresponding to the obstacle area information does not intersect with the area corresponding to the projection area information, indicating that the detection probe will not make contact collision with the convex structure on the non-detection point when descending. At this time, control the detection probe to descend to detect the detection point.

[0183] Step S805: If the area corresponding to the obstacle area information intersects with the area corresponding to the projection area information, obtain the non-detection point obstacle distance information;

[0184] The area corresponding to the obstacle area information intersects with the area corresponding to the projection area information, indicating that the detection probe will make contact collision with the convex structure on the non-detection point during the descending process, resulting in the detection probe not being perpendicular to the calibration plane. The distance corresponding to the non-detection point obstacle distance information is the distance value of the intersection area of the obstacle area and the projection area in the detection path direction. The acquisition of the non-detection point obstacle distance information can be achieved by pre-installing a camera on the clamping manipulator to obtain image features and modeling through the image features to determine the distance value of the intersection area in the detection path direction.

[0185] Step S806: Determine the compensation point position information according to the detection point obstacle distance information and the preset radius information;

[0186] The distance corresponding to the obstacle distance information is the minimum distance between the current detection point and the adjacent normal convex structure. The obstacle distance information is obtained through the information recorded on the workpiece production drawing. The radius corresponding to the preset radius information is the radius distance of the detection probe. The method for determining the position of the compensation detection point corresponding to the compensation point position information is as follows: First, sum the radius of the detection probe and the obstacle distance, and define the obtained sum value as the compensation movement distance. The position of the compensation detection point is to move a length corresponding to the compensation movement distance along the detection path direction from the position where the current detection point is located.

[0187] Step S807: Determine the compensation area information according to the compensation point position information and the division method, and judge whether the area corresponding to the compensation area information intersects with the area corresponding to the obstacle area information;

[0188] The area corresponding to the compensation area information is: a circular area centered on the position of the compensation detection point and divided by the radius of the detection probe. The purpose of determining whether the compensation area intersects with the obstacle area is to find out whether there will still be a collision with the adjacent convex structure when the detection probe detects the position of the compensation point.

[0189] Step S808: If the area corresponding to the compensation area information does not intersect with the area corresponding to the obstacle area information, control the detection device to perform a detection operation on the compensation detection point;

[0190] If the area corresponding to the compensation area information does not intersect with the area corresponding to the obstacle area information, it means that the detection probe will not collide with the adjacent convex structure when detecting the compensation point. At this time, control the detection device to descend for detection.

[0191] Step S809: If the area corresponding to the compensation area information intersects with the area corresponding to the obstacle area information, define the compensation point corresponding to the position information of this compensation point as a failed compensation point, and control the detection device to move to the next detection point for detection operation.

[0192] If the area corresponding to the compensation area information intersects with the area corresponding to the obstacle area information, it means that when the detection probe descends to the plane where the compensation detection point is located for detection, the detection probe will contact and collide with other adjacent convex structures. At this time, define the compensation point corresponding to the position information of this compensation point as a failed compensation point, do not detect this failed compensation point, and control the detection probe to move to the next detection point for detection operation.
