涡旋盘非标自动化装配设备研发

Design of the Automatic Assembling Special Machine for Vortex Plate

空调压缩机中的涡旋盘正背面需要装配销钉和阀片。目前该道工序主要是由人工完成,劳动强度大,效率低,次品率高。针对这种现状,根据涡旋盘装配的特点,设计了一套涡旋盘自动装配装置,详细介绍了总体设计方案、结构布局、机械结构、电气结构和控制系统。设备主要分为涡旋盘上料工站、定位销自动压装工站和阀板自动安装与气密性检测工站,电气控制部分采用三菱IQ-F系列80点的PLC,外加128点的扩展IO以及4路模拟量输入,方便以后PLC并入MES系统,并且该系列具有较好的FB功能,可以将一些通用的控制方式写入FB,方便今后类似的设备直接调用调试好的程序,避免重写带来的不必要麻烦,考虑到有3个伺服电机,方便伺服与PLC通讯,减少焊线带来的不必要的问题,采用三菱JET系列的伺服,与PLC进行CC-LINK IE TSN组态,使用绝对值系统,即使断电后,伺服放大器依旧能识别电机的位置。经实践该套装置大大提高了生产效率、提高了产品质量、降低了人工成本。

Pins and valve plates need to be assembled on the front and back of the vortex disc.At present,this process is mainly completed manually,with high labor intensity,low efficiency,and high defect rate.In response to this situation,based on the characteristics of vortex disc assembly,a set of vortex disc automatic assembly device is designed,and introductions of the overall design plan,structural layout,mechanical structure,electrical structure,and control system are provided detailedly.The equipment is mainly divided into a vortex plate loading station,a positioning pin automatic press fitting station,and a valve plate automatic installation and airtightness testing station.The electrical control part adopts the Mitsubishi IQ-F series 80 point PLC,with an additional 128 point extended IO and 4 analog inputs to facilitate the integration of the PLC into the MES system in the future.The series also has good FB function,which can write some general control methods into the FB,convenient for similar devices to directly call and debug the program in the future,avoiding unnecessary trouble caused by rewriting.Considering that there are three servo motors,which facilitate communication between the servo and PLC,and reduce unnecessary problems caused by welding wires,mitsubishi JET series servo is adopted,and CC-LINK IE TSN configuration is carried out with PLC.Using an absolute value system,even after power outage,the servo amplifier can still recognize the position of the motor.Through practice,this device has greatly improved production efficiency,improved product quality,and reduced labor costs.
