Automatic soldering machine system

Release time: 2016.12.19 News source: Shenzhen Tedede Automation Co., Ltd. Browse times:

Based on the analysis of the functional requirements of the automatic soldering machine system, a set of design schemes for an automatic soldering machine control system based on PLC technology is proposed. The hardware composition and selection principles of the soldering system are briefly discussed. This paper introduces the software implementation of a fully automatic soldering machine system. The practical application shows that the automatic soldering system can not only meet the requirements of solder production, but also have the characteristics of high production efficiency, strong stability and simple maintenance.

Automatic soldering machine refers to a soldering device that can complete the complete welding process including the positioning of solder joints, soldering, soldering and solder residue cleaning. Although soldering machines have been widely used in the electronics industry, With the updating of welding process, the change of welding materials and the increase of welding workload, the welding reliability, welding quality and welding efficiency of traditional soldering machines can no longer meet the needs of modern coal welding production. Demand, here introduces a set of schemes based on PLC control technology and combined with photoelectric sensors and other hardware to build an automatic soldering machine control system to achieve complete automation of the soldering process and improve the working efficiency of the soldering machine.

System functional requirements:
In daily industrial production, there are many components that need to be fixed and connected depending on the quality of the soldering process. Accuracy will directly affect the function of the component. It is also one of the determinants of product safety and reliability. Welding reliability is taken into consideration according to the soldering requirements of the product on an enterprise's automated production line. Quality and efficiency. The automatic solder control system needs to have the following functions:
(1) It can ensure the accurate positioning of solder joints and effectively reduce the rate of missed and missed soldering;
(2) Relevant parameters such as the soldering system heating temperature soldering speed and wire diameter can be adjusted according to the actual situation;
(3) The system has the function of temperature alarm and tin wire alarm.
(4) The soldering system needs to have a good human-machine interaction interface, which can monitor the system status in real time, prompt alarm information and other functions, and can set the relevant parameters in the interface.

Overall system design
The automatic soldering system adopts PLC as the control center of the entire system. Through the collection and processing of the in-position signal, temperature signal and safety grating signal, it ensures the safety and reliability of the entire automatic soldering process. The electric cylinder controller realizes precise control of the fixture position, movement speed and other parameters, so as to achieve accurate positioning of the welding point. The soldering device can be used to achieve the system heating temperature and tin speed adjustment. At the same time, high temperature and lack of tin wire alarm can be realized. Touch screen and PLC are used to realize information interaction to achieve real-time display of the production status of the system and prompt the system alarm information # to control the production process. The system software is compiled by Windows-based STEP7-Micro / WIN32 and combined with Wincc configuration software Monitoring of soldering process.
