Embodiment 1

[0035] See figure 1 , the application provides a calibration method for console positioning accuracy, comprising the following steps:

[0036] S100: Fix a calibration reference device on the operating table.

[0037] Wherein, the calibration reference device may be a display screen. When fixing the display screen, make it face up and place it flat on the operating platform, and ensure that when the operating platform moves, the operating platform and the calibration reference device are relatively stationary, that is, no relative movement occurs. The display screen contains pixel units neatly arranged in rows. The size of the pixel unit is at the micron level, so the calibration accuracy is higher when the display is used as the calibration reference device. The positioning accuracy of the calibration reference device should be higher than that of the operating table.

Abstract

The invention relates to a method and system for calibrating the positioning precision of an operation table. The method comprises the following steps that a reference calibration device is fixed to the operation table; a reference line is arranged on the reference calibration device; a mark line is arranged on the operation table and is aligned with the reference line; an instruction is sent to enable the operation table to move a preset distance in the preset direction; the distance between the reference line of the reference calibration device and the mark line on the operation table is acquired and is compared with the preset distance so as to obtain the positioning deviation value of the operation table; and the moving distance of the operation table is adjusted according to the obtained positioning deviation value. The method and system for calibrating the positioning precision of the operation table have the advantages that the deviation value between the distance between the reference line and the mark line and the preset distance is calculated, so that the positioning precision of the operation table can be calibrated, and therefore the problems that in the prior art, thepositioning precision of an operation table is limited and cannot be measured accurately, and the requirement of the product machining precision can be hardly met can be solved.

Description

technical field [0001] The invention relates to the field of automation, in particular to a method for calibrating the positioning accuracy of an operating platform. Background technique [0002] In the field of mechanical automation processing and manufacturing, with the continuous refinement of product parts, the requirements for product processing accuracy are also getting higher and higher. The positioning accuracy of the operating table will directly affect the processing accuracy of the product, thereby affecting the pass rate of the product. Therefore, the positioning accuracy of the console plays a decisive role in the overall performance of the automation equipment. For example, when using laser cutting equipment to cut workpieces, it is necessary for the operation table to accurately position the workpiece to complete high-precision cutting. [0003] In the process of realizing the traditional technology, the inventor found that there are the following technical ...
