Fig. 1 is a flow chart of a method for automatically detecting paint spraying according to an embodiment of the present invention. As shown in fig. 1, an automatic detection painting method includes the steps of: acquiring qualified specification parameters of a workpiece to be painted, and setting a detection error range according to the qualified specification parameters;
placing a material to be painted on a roller way, and detecting the actual specification parameters of a workpiece to be painted by using a detector;
comparing the actual specification parameters with the detection error range, and screening qualified data in the detection error range from the actual specification parameters; determining a painting area of the workpiece to be painted according to the qualified data; acquiring displacement data of a workpiece to be painted, and determining that the workpiece to be painted reaches a painting position according to the displacement data; acquiring position data of the paint spraying trolley, and determining that the paint spraying trolley reaches a paint spraying position according to the position data of the paint spraying trolley; and when the workpiece to be painted reaches the painting position and the painting trolley reaches the painting position, controlling the painting trolley to paint in the painting area.
Step S01: and acquiring qualified specification parameters of the workpiece to be painted, and setting a detection error range according to the qualified specification parameters.
In the invention, the qualified specification parameters are as follows: the original width value of the workpiece to be painted.
In the embodiment of the invention, the workpiece to be painted can be a steel plate, and the original delivery width of the steel plate is 0.3 m. And setting an error range in detection according to qualified specification parameters, wherein the width error range is +/-20 mm. When the steel plate is rectangular, the width is uniform, and when the steel plate is irregular, the width of each position is different, and an error range needs to be set according to the width of the specific position.
Step S02: and (3) placing the material to be painted on a roller way, and detecting the actual specification parameters of the workpiece to be painted by using a detector.
In the present invention, the actual specification parameters are: and (5) detecting the actual width value of the workpiece to be painted.
In the embodiment of the invention, in the actual production process, the steel plate is placed on a roller way in a workshop and runs along with the roller way, and when the steel plate runs to the position below the detector, the detector detects the steel plate. The detector will carry out multiunit detection, and every group detected data includes: and detecting two data of the distance from the initial position to the left edge of the steel plate and the distance from the initial position to the right edge of the steel plate, and subtracting the two data to obtain the actual width value of the steel plate in the group of data. For example, when the first group of data is detected, the distance from the detection initial position to the right edge of the steel plate is 1.7 m; if the distance from the initial position to the left edge of the steel plate is 2 meters, the actual width of the first group of detected steel plates can be obtained to be 0.3 meter. The steel sheet removes the in-process on the roll table, reaches the part below the detector, and the detector detects out promptly from detecting initial position to the steel sheet left side along the distance and detecting initial position to the steel sheet right side along the distance, and according to the length difference of steel sheet, the data set quantity that detects is different, and the steel sheet is longer, and then the data set quantity is more.
Step S03: and comparing the actual specification parameters with the detection error range, and screening qualified data in the detection error range in the actual specification parameters.
In the embodiment of the invention, after the detector detects multiple groups of actual width value data of the steel plate, the detected data are excessive, wherein data with large deviation may occur, and the detected data need to be screened. And comparing the detected data, namely the width data obtained by subtracting the distance from the detection initial position to the left edge of the steel plate and the distance data from the detection initial position to the right edge of the steel plate with the detection error range data, deleting the error data exceeding the detection error range, and finally retaining five groups of data.
Step S04: and determining the painting area of the workpiece to be painted according to the qualified data.
In the embodiment of the invention, the width data of different positions of the steel plate can be determined through the screened five-combination-lattice data, so that the placing position and the shape of the steel plate on a roller way can be determined, and the area to be painted on the steel plate can be determined according to the position and the shape. After the steel plate runs on the roller way and is detected by the detector, the steel plate reaches the lower part of a spray gun of a paint spraying trolley in a paint spraying room and is prepared to be sprayed in a paint spraying area. Because the data transmission speed is high, the data processing capacity is large, error data can possibly occur in the five groups of screened data, the five groups of data of the actual specification parameters of the screened steel plates need to be judged before the paint spraying, namely whether the five groups of data meet the qualified specification parameters of the steel plates, even if one group of data meets the qualified specification parameters of the steel plates, the paint spraying can be normally carried out, and if none of the five groups meets the qualified specification parameters, the paint spraying cannot be carried out.
Step S05: acquiring displacement data of a workpiece to be painted, and determining that the workpiece to be painted reaches a painting position according to the displacement data;
in the embodiment of the invention, when the steel plate runs on the roller way, the steel plate firstly passes below the detector, and after the detector detects the width data of the workpiece to be painted, the steel plate continuously runs to the painting position below the painting trolley. And in the steel plate operation process, continuously acquiring the displacement data of the steel plate, and judging that the steel plate runs to the paint spraying position below the paint spraying trolley according to the displacement data.
Step S06: acquiring position data of the paint spraying trolley, and determining that the paint spraying trolley reaches a paint spraying position according to the position data of the paint spraying trolley;
step S07: and when the workpiece to be painted reaches the painting position and the painting trolley reaches the painting position, controlling the spray gun to be opened to paint in the painting area.
In the embodiment of the invention, when the steel plate runs on the roller way and reaches the position below the paint spraying trolley, the position data of the paint spraying trolley is obtained, and when the paint spraying trolley is judged to run to the edge position on the left side of the steel plate, the paint spraying trolley is controlled to spray paint on the steel plate from left to right.
In the present invention, the method further comprises the steps of: and acquiring equipment data influencing the accuracy of the paint spraying position in the equipment used during paint spraying, and compensating the paint spraying position according to the equipment data.
In the embodiment of the invention, in actual operation, besides the data of the paint spraying position influenced by the displacement of the steel plate on the roller way, the paint spraying position data is influenced by the opening speed of the electromagnetic valve of the spray gun, the pressure and the flow speed of the oil way of the paint spraying trolley, the placement angle of the spray gun, the paint resistance, the speed of the paint spraying trolley and the like, and the data of the paint spraying position is influenced by the factors, so that the data of equipment which influences the paint spraying accuracy and is involved in the paint spraying process needs to be acquired before the paint spraying is carried out, and the. Taking the opening of the electromagnetic valve of the spray gun as an example, when the electromagnetic valve is opened until the electromagnetic valve is completely opened, an action process time t1 needs to be passed, when the moving speed of the paint spraying trolley is v, the compensation distance s1 needs to be s1= vt1 (calculated according to a constant speed), and the data of the paint spraying position is corrected through the distance s1, for example, the original paint spraying position is: and the steel plate is taken as a starting point at the position below the detector, and the position moved to 3 meters in the direction of the spray gun is taken as a paint spraying position, so that the compensated paint spraying position = 3 meters-s 1. Other compensation factors need to give out compensation amount comprehensively according to actual conditions, and the compensation amount is not fixed and is adjusted along with the production line speed and the specific conditions of equipment.
According to the automatic detection paint spraying method, the actual specification parameters and the qualified specification parameters detected when the material to be sprayed is sprayed are compared and screened, and the error data outside the detection error range in the detection data are removed by screening, so that the accuracy of calculating the paint spraying area is ensured. When calculating the area of spraying paint, in every group detected data, detect initial position and get the minimum to the left edge, detect initial position and get the maximum to the right edge, avoided appearing leaking because of the paint spraying range undersize that detects and spout with the mistake and spout the phenomenon, judge simultaneously that the material of waiting to spray paint that is moving on the roll table accords with the material that will actually spray paint whether, if accord with then spray paint, can not spray paint if not accord with then, avoided spouting the problem that causes the paint waste because of the mistake.
