Embodiment Construction
[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0032] see figure 1 and figure 2 , a method for finding the starting point coordinates of a processed workpiece, comprising a processing head 3 and a processing area 2, the processing head 3 is provided with an infrared distance measuring sensor 4, the processing area 2 includes a base plate, and the distance measuring sensor 4 faces the base plate. The actual position of the processing head 3 and the installation position of the infrared distance measuring sensor 4 are not on the same straight line, which can be compensated through the built-in progr...

The invention provides a device for finding a workpiece machining starting point coordinate. The device comprises a machining head and a machining area, and a distance measuring sensor is arranged onthe machining head. The using method of the device comprises the steps that a workpiece is placed in the middle position of the machining area, and the edge of the workpiece is parallel to the X axisand the Y axis of the machining area; the machining head travels along the diagonal line of the machining area; when the machining head passes through the workpiece, the distance measuring sensor thedistance change; the machining head travels for a distance of L1; the machining head moves in the X-axis positive direction of the machining area until the machining head moves out of the workpiece, and the movement distance is recorded as X1; the machining head moves for a distance of X2 in the X-axis negative direction of the machining area, and returns to the top of the workpiece; the machininghead moves in the Y-axis positive direction of the machining region until the machining head moves out of the workpiece, and the movement distance is recorded as Y1; and the machining head moves forthe distance of X2 in the X-axis positive direction of the machining area, and a starting point position is positioned. According to the method, the machining starting point of the workpiece can be quickly positioned, positioning is simple, fast and accurate, and the equipment cost is low.
Description
technical field [0001] The invention relates to the technical field of processing methods, in particular to a method and a device for finding coordinates of a starting point of a processing workpiece. Background technique [0002] Currently on the market, the processing platforms used for CNC processing, laser engraving, etc. need to determine the specific position of the workpiece after placing the workpiece to be processed, so as to determine the starting point of processing. If the starting point is not confirmed but only roughly moved to the starting point of the object, it is easy to waste part of the area of the workpiece. The currently available method is to determine the position of the workpiece by shooting with a camera, and then move the processing head to the starting point of the workpiece. Using the camera can quickly determine the starting point of the workpiece, and the accuracy is very high. However, the cost of using a camera for a low-cost processing pl...
