4 key points of computer quilting machine control system

电脑绗缝机控制系统的关键技术为鞍架和罗拉与针排的联动控制技术，缝机控制系统总体技术设计起点高、兼容性较好、抗干扰能力强，按照国际设计的惯例和电脑绗缝机的特定要求进行优化设计。电脑绗缝机厂家介绍其技术要点主要有以下几点：

The key technology of the computer quilting machine control system is the linkage control technology of saddle frame and roller with needle row. The overall technical design of the sewing machine control system has high starting point, good compatibility and strong anti-interference ability. The main points of the computer quilting machine are as follows:

1、在鞍架和罗拉系统控制技术中，根据鞍架或罗拉实际负载、滚珠丝杠和皮带传动原理、绗缝针速和针迹以及绗针与压板相位等诸多参数要求，合理选择鞍架或罗拉驱动电机，精确计算鞍架或罗拉加速度及移料时间，优化设计鞍架或罗拉驱动指令控制曲线，确保绗缝质量和绗缝产量，提高鞍架或罗拉系统控制技术整体设计水平，用步进电机代替交流伺服电机驱动鞍架，从而提高鞍架和罗拉系统整体性能指标。

1. In the control technology of saddle and roller system, according to the actual load of saddle or roller, the principle of ball screw and belt drive, the needle speed and stitch of quilting, and the phase of quilting needle and pressing plate, etc. and many other parameters requirements, the saddle or roller drive motor is reasonably selected, the acceleration of saddle or roller and the moving time of material are accurately calculated, and the optimum design is carried out. Saddle frame or roller drive command control curve to ensure quilting quality and yield, improve the overall design level of saddle or roller system control technology, using stepper motor instead of AC servo motor to drive saddle frame, thereby improving the overall performance index of saddle frame and roller system.

2、在主轴系统控制技术中，根据主轴实际负载、皮带传动原理、绗缝针速和绗缝针迹等诸多参数要求，合理选择主轴驱动电机，计算主轴加速度，优化设计主轴驱动指令变速控制曲线，确保绗缝质量和绗缝产量，提高主轴系统开发技术整体设计水平，用变频器带异步电动机驱动主轴，从而提高主轴系统整体性能指标。

2. In the spindle system control technology, according to the actual load of the spindle, belt drive principle, quilting needle speed and quilting stitch and many other parameters, select the spindle drive motor reasonably, calculate the spindle acceleration, optimize the spindle drive command speed change control curve, ensure quilting quality and quilting output, improve the spindle system The overall design level of the technology is developed, and the main shaft is driven by a frequency converter with an asynchronous motor, so as to improve the overall performance index of the main shaft system.

3、在整体系统硬件和结构上，根据系统性能和功能指标，优化设计系统电路图，仔细进行系统耐工业环境设计、系统性能及工作稳定性设计与系统安全性设计等技术措施，严格采用元器件控制及降额设计方法，合理选择电脑芯片和各种元器件及集成电路芯片，以最优价格和最高可靠性实现所需功能单元。采取屏蔽、热设计和正确布线方式实现工业环境电磁兼容性。

3. On the hardware and structure of the whole system, according to the system performance and function index, the circuit diagram of the system is optimized, the technical measures such as industrial environment resistance design, system performance and working stability design and system safety design are carefully carried out, the component control and deduction design method are strictly adopted, and the computer core is reasonably selected. Chips and a variety of components and integrated circuit chips, with the highest price and reliability to achieve the required functional units. The electromagnetic compatibility of industrial environment is realized by shielding, thermal design and proper wiring.

4、在系统控制软件中，针对软件缺陷的固有性、出错环境的复杂性，在软件设计上也采取了一系列防范措施，并在绗缝过程中，实时监测各种执行机构，杜绝干扰等因素造成的误动作，提高了系统的可靠性能。

4. In the system control software, aiming at the inherent nature of the software defects and the complexity of the error environment, a series of preventive measures have been taken in the software design. In the process of quilting, real-time monitoring of various actuators to eliminate the interference and other factors caused by misoperation has improved the reliability of the system.
