Method and system for variable return to zero based on multi-axis point drilling rig motion platform

Abstract

The invention discloses a variable zero return method and system based on a multi-axis point drilling rig motion platform, which is used for realizing self-defined zero return on the multi-axis motion platform. The system includes the upper computer display screen, point drill control board and a set of multi-axis servo system. The main process includes: touch on the upper computer display screen to set the number and order of the axes returning to zero, as well as the origin direction and zero returning speed, and the setting is completed. Finally, the host computer simplifies the zero-return information into an array type according to the display and sends it to the control panel of the point drilling machine for storage. When the control board receives the zero-return command from the host computer, it reads and analyzes the saved zero-return information, and sends a zero-return command to the servo system to control the moving parts to complete the zero-return operation. The invention is flexible and efficient, completes the setting of the zero-returning process through a simple touch display method, and converts it into a simple array structure to control the zero-returning process, has high stability and reliability, and effectively improves production efficiency.

[0002] In recent years, with the continuous expansion of decorative demand for various hardware, photo frames, handicrafts, key chains and other products, manual dispensing and spot drilling can no longer meet the production and process requirements

The invention of the automatic point drilling machine has improved the accuracy and production efficiency. However, after changing different bins or products during processing, it is necessary to return to zero and teach again to reduce coordinate errors. The current method of returning to zero is to return to zero for all axes each time by pressing All return to zero in a certain order, this method cannot adapt to the situation when only the silo is replaced or only the product is replaced, which increases the workload of reprogramming and wastes time and manpower

[0003] Machines that realize automatic processing must undergo a zero-return operation before starting to move. At present, it is widely used to return all motion axes to zero in a specific order, or to realize the zero-return of some axes through PLC programming. These methods have poor variability and are difficult to achieve. Complicated, it is cumbersome and inefficient for multi-axis point drilling machines. For example, when the workpiece is not processed and the silo is empty, it only needs to replace the silo, and then return to zero to record the two axes of the silo coordinates and start again. Teach the bin coordinates without returning the axis that controls the position and attitude of the workpiece to zero and then re-teach; similarly, when a batch of products is processed, there is still a large amount of surplus in the bin, and there is no need to change the bin coordinates, as long as Return the workpiece position axis to zero and place the workpiece to be processed, then re-teach the workpiece coordinates
