【摘要】：人们对通讯、IT、消费类电子产品的需求推动了片式电感制造业的迅猛发展,片式电感的需求量在每年数百亿只以上。然而片式电感外形多变、制程复杂的特点使得它很难象其它片式元器件那样形成大规模的自动化生产,至今仍然停留在劳动密集型的手工生产或者半自动生产阶段,其生产效率低下,质量难以保证。 研制一套具有完全知识产权、自动化程度高、工作可靠的绕线型片式电感器自动化生产装备,将片式电感器件的供料、定位、装夹、绕线、焊接等功能集成在一台机器上,实现该种片式电感器的自动化生产。 该装备主要由电机来控制自动供料机构、顶料装置、定位装央机构、绕线机构、排线机构、焊接机构。硬件方面采用嵌入式ARM主控板,利用PWM电路控制绕线机工作台的Z方向的焊接电机上下和左右方向的移动,实现焊接电机的精确定位；并控制储线环送线速度；它还通过中断接口对定位装央机构、送断线压块、卸料喷嘴等辅助机构中各气缸电磁阀；焊接轴、绕线轴的传感器；焊接轴、引线轴的限位开关进行控制。设计运动控制器通过控制两个伺服电机来实现绕线轴和排线轴X、Y方向的的联动控制、完成插补动作,实现漆包线的绕制；用触摸屏作为设备的主要控制面板及显示终端,用来进行工艺参数的设定以及工作状态的选择或监控。 软件设计方面,将嵌入式实时操作系统μC/OS-Ⅱ移植到ARM处理器S3C44BOX上,并编写了系统的启动代码；对绕线机每个轴的运动控制的各个功能模块,编写了运动控制的API函数库。应用程序通过调用API函数库,可设计出完成绕线工作的控制系统。
[Abstract]:The demand for ITT and consumer electronic products has promoted the rapid development of chip inductor manufacturing industry. The demand for chip inductors is more than 10 billion each year. However, the variable shape of chip inductor and complicated process make it difficult to form large-scale automatic production like other chip components, and still remain at the stage of labor-intensive manual production or semi-automatic production. Its production efficiency is low, the quality is difficult to guarantee. A set of automatic production equipment of winding type inductor with complete intellectual property right, high degree of automation and reliable operation is developed. The functions of feeding, positioning, clamping, winding and welding of chip inductors are integrated on a single machine. The automatic production of the chip inductor is realized. The equipment is mainly controlled by motor automatic feeding mechanism, top material device, positioning center mechanism, winding mechanism, wire arrangement mechanism, welding mechanism. The embedded arm main control board is used in hardware, PWM circuit is used to control the movement of welding motor in Z direction of winding machine worktable, to realize the precise positioning of welding motor, and to control the wire feeding speed of storage loop. It also controls the solenoid valve of the cylinder in the auxiliary mechanism of locating the center mechanism, the breaking line pressing block, the discharging nozzle, the sensor of the welding shaft and the winding axis, and the limit switch of the welding shaft and lead shaft through the interrupt interface. The motion controller is designed to control two servomotors to realize the linkage control of the winding axis and the wiring axis XY direction, to complete the interpolation action, to realize the winding of the enamelled wire, and to use the touch screen as the main control panel and display terminal of the equipment. Used for setting process parameters and selection or monitoring of working status. In the aspect of software design, the embedded real-time operating system 渭 C / OS- 鈪，
