Toothbrush bristle planting system and method based on electronic cam control

Abstract

The invention discloses a toothbrush bristle planting system and method based on electronic cam control. The toothbrush bristle planting system comprises an XY working platform, a main shaft, a signal acquisition module and a controller. One motion period of the toothbrush bristle planting system has two control intervals which are respectively positioned in a synchronous control interval and a non-synchronous control interval. The main shaft performs one-time lifting reciprocating motion in the motion period; and in the process that the main shaft moves from the starting point of the synchronous control interval to the end point of the synchronous control interval, the XY working platform moves along with the main shaft, and in other time, the XY working platform is kept static. The invention provides a reasonable speed change curve when the main shaft goes in and out of the synchronous control interval, so that the speed of the main shaft is in smooth transition between the synchronous control interval and the asynchronous control interval, the moving speed of the XY working platform is in smooth transition between the holes in cooperation with an electronic cam algorithm, vibration generated when the XY working platform stops is inhibited, and the working efficiency is improved. Therefore, the flocking process is more accurate, and the product quality is higher.

Description

technical field [0001] The present invention relates to the field of servo motor control, and more particularly, to an electronic cam control device and method. Background technique [0002] With the continuous development of national economic level, people pay more and more attention to maintaining oral health. Having strong, white teeth is the guarantee of a healthy life, so the demand for toothbrush products is also increasing day by day. The automatic hair planting machine is an electromechanical integrated device for planting hair on the toothbrush handle, and is an important tool in the production process of the toothbrush. In the traditional hair planting machine, the main shaft and the XY work platform are matched by a mechanical cam, which requires a sensor to trigger a signal. On the one hand, it will increase the manufacturing cost of the equipment. On the other hand, it may also occur due to sensor damage or mechanical cam position deviation. cause the control ...

Problems solved by technology

Although this method can realize the speed planning of any moving distance, it cannot guarantee the execution time of the speed curve.

Therefore, the user needs to set parameters according to the spindle speed and the maximum moving distance of the processed plate and the speed planning parameters of the force, but in fact the spindle speed and the maximum moving distance often change, so it may appear that the speed curve of the relevant mechanism is different from the actual working condition. matching situation

[0004] In addition, the moving speed of the operating mechanism of the hair tufting machine using the traditional mechanical cam is divided into stages, and the speed is constant during work. In a high-speed, frequent start-stop mechanism such as wool planting, the use of mechanical cams will generate greater working noise and mechanical vibration, which will reduce the quality of wool planting
