执行结构设计

北京理工大学珠海学院 2020 届本科生毕业设计 执行结构设计执行结构设计摘要ICT，英文全称 In-Circuit-Tester，也称在线测试仪。它是当下 PCB 相关生产企业必备的生产测试设备，别名 ICT 治具。现在，普通的测试治具已经是成熟的产品，本次设计主要改进普通治具部分结构以及降低相关制造成本，主要以普通的测试治具作为原型，在普通的测试治具的基础上添加机构，使一台治具可以完成两段式的微针测试，降低了成本，也提高了生产效率。同时设计一款新型散热器，利用压缩空气进行工作，降低治具工作中芯片所产生的温度。本次设计主要有治具各部分的结构设计、运动解析和尺寸设计，以及部分零部件的受力校核和仿真分析。主要使用了 AutoCAD、Soildworks 等工程软件进行辅助设计，使用了 Soildworks Simulation进行受力、热力仿真，使用了 Soildworks Flow Simulation 进行流体力学仿真。关键词：ICT；治具；结构设计；仿真北京理工大学珠海学院 2020 届本科生毕业设计 北京理工大学珠海学院 2020 届本科生毕业设计Perform structural designAbstractICT, English full name in circuit tester, also known as online tester. It is the necessary production and test equipment for PCB related manufacturers, also known as ICT fixture. Now, the common test fixture is a mature product. This design mainly improves the structure of the common fixture and reduces the related manufacturing cost. It mainly takes the common test fixture as the prototype, and adds a mechanism on the basis of the common test fixture, so that one fixture can complete the two-stage micro needle test, reducing the cost and improving the production efficiency. At the same time, a new type of radiator is designed, which uses compressed air to reduce the temperature produced by the chip in the work of the fixture. This design mainly includes the structure design, motion analysis and dimension design of each part of the fixture, as well as the stress check and simulation analysis of some parts. It mainly uses Auto...
