Problems solved by technology
[0003] The purpose of the embodiments of the present invention is to provide a precise spraying method and system to solve the problems existing in the prior art. In order to ensure the efficiency of spraying, the speed of the conveyor belt will be set faster, which may cause the spraying device to fail to return to the preset processing starting point. , when the next workpiece exceeds the preset processing starting point, the spraying device is not synchronized with the workpiece to be processed, resulting in a high probability of missed coating and low spraying efficiency

Embodiment Construction
[0019] In order to make the object, technical solution and advantages of the present invention 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.
[0020] refer to figure 1 , figure 1 A schematic diagram of the operating environment of the precise spraying method provided by the embodiment of the present invention.
[0021] In this figure, the upper C-axis is connected and drives the spraying device, and the C-axis and the spraying device maintain the same speed. Assuming that there are few workpieces to be processed that need to be sprayed, when the workpieces to be processed reach the lower preset processing starting point, the C-axis drives The spraying device runs from left to right at the same speed as the conveyor belt, and at the same...

The invention is applicable to the technical field of numerical control and provides a precision spraying method and a precision spraying system. The precision spraying method includes: judging whether a workpiece to be processed arrives at a chase position or not when a spraying device returns to a preset processing start point; when the workpiece arrives at the chase position, calculating a moving distance of the workpiece to be processed in the chasing process according to a preset chasing speed of the spraying device, a preset speed of a conveying belt and the distance the workpiece to be processed exceeding the preset processing start point, setting a running distance and a running speed of a C shaft according to the moving distance of the workpiece to be processed, the distance the workpiece to be processed exceeding the preset processing start point and a chasing speed of the spraying device, and converting the running distance and the running speed of the C shaft into pulses; and driving the C shaft to run for the running distance at the running speed according to the pulses. Aiming at the situation that the workpiece to be processed exceeding the preset processing start point, a chasing method is designed for the workpiece to be processed, and the problems that a spraying missing probability is large and spraying efficiency is low in the prior art are solved.
Description
technical field [0001] The invention belongs to the technical field of numerical control, and in particular relates to a precise spraying method and system. Background technique [0002] In the digital control spraying system, the spraying device is driven by the C-axis, and sprays the workpiece after waiting for the workpiece to arrive at the preset processing starting point. Since the workpiece moves with the conveyor belt, the spraying device needs to be driven by the C-axis to maintain the same speed as the conveyor belt and at the same time. Move in the opposite direction to complete the spraying of the workpiece. After the spraying is completed, return to the preset processing starting point and wait for the arrival of the next workpiece. Because the workpieces transported on the conveyor belt are of different sizes, if the speed of the conveyor belt is slow and the workpieces are small, the spraying device may be in a waiting state after completing a workpiece. The ef...
