摘要变压器铁芯作为变压器的核心部分，它的质量直接影响到变压器的技术性能、 经济指标和运行的安全可靠，因此它的制造技术改良和质量十分重要。但由于硅钢 片叠装工艺的特殊性，目前变压器铁芯主要通过手工叠装这一现状以及生产率低下， 质量参差不，工作强度大，人工叠片容易发生重片、缺片，成本问题，设计了一套 变压器硅钢片自动叠片装配生产线。对自动叠片机的框架结构，三维运动机构的模 式、步进电机驱动送料提升装置、真空吸盘吸取硅钢片、自动拆箱等方面进行研究 设计。通过 PLC 对整个叠片过程进行控制，通过传感器对工件是否就位进行识别， 通过气缸控制气压马达的旋转，控制真空吸盘的旋转和伸缩运动。通过步进电机控 制供料台 XY 轴向运动，实现将硅钢片送至真空吸盘正下方。通过 PLC 控制吸盘吸取 次数进行控制叠片数量。自动叠片机的发明，将会解决手工叠装生产率低下，质量 参差不齐，叠装缺片，重片的问题，大大降低了企业成本。82125

Abstrac Transformer core as a core part of the transformer, he directly affects the quality of the technical performance and economic indicators and running of the transformer in the safe and reliable, so it's manufacturing technology improvement and the quality is very important。But due to the particularity of silicon steel sheet pile loading process,the current transformer core is mainly through manual pile up with the status quo and the productivity is low, Quality and level is low, working strength is big, the artificial laminated prone to overlap lack of pills and cost problem, design a set of automatic transformer silicon steel sheet laminated assembly line。The frame structure of the automatic lamination machine, three-dimensional motion mechanism model, stepping motor driven feeding mechanisms, vacuum suction cup lifter to research the design of silicon steel sheet, etc。Through the PLC to control the whole process of laminated, through the sensor which can identify whether the workpiece in place and electromagnetic valve control cylinder cylinder movement, control the rotation of the vacuum suction cups, scalable motion。Controlled by pneumatic motor XY axial

movement, will deliver silicon steel Sent to the suction under the vacuum chuck。

Keywords：transformer, lamination, air motor,vacuum grip device, dumping gear,Screw-thread hoisting mechanism,PLC。
