Dual-core two-freedom-degree high-speed full-automatic tin soldering robot servo controller

Abstract

The invention discloses a dual-core two-freedom-degree high-speed full-automatic tin soldering robot servo controller which comprises a power source unit, a main control unit, an image capturing and processing unit and a tin soldering unit. The power source unit comprises an alternating current power source and a battery, the battery is a lithium ion battery, the main control unit comprises a digital signal processing chip and a field-programmable gate array chip which are connected, and the tin soldering unit comprises two-freedom-degree control and tin-discharging control. One end of the main control unit is connected with the power source unit, the other end of the main control unit is connected with the image capturing and processing unit, and the field-programmable gate array chip is connected with the tin soldering unit. According to the method, the dual-core two-freedom-degree high-speed full-automatic tin soldering robot servo controller is high in automation degree, working efficiency and motion accuracy and effectively protects the battery from impact of a large current, and the temperature and the length of tin-feeding are easy to control.

[0002] Today, with the rapid development of high technology, traditional soldering has become increasingly backward. With the mass production of electronic products, the method of manually using soldering iron tools to solder the solder joints on the PCB board point by point can no longer adapt to market requirements and production. Efficiency and Product Quality

The new type of soldering robot replaces people from the harsh and dangerous working environment and performs civilized production. However, the existing soldering robot can only repeatedly perform simple straight lines or arcs on a straight line or a two-dimensional plane. Spot welding, or point-to-point spot welding of some positions according to certain rules, often has the following problems in the actual soldering process: (1) In the initial stage of soldering, it is manual movement that pushes the soldering robot to the starting point Position, and then only rely on the human eye to correct the initial position, so that the accuracy is greatly reduced, (2) In the control mode based on the microprocessor + special motion control chip, generally a dedicated control chip controls a motor, and takes up a lot of Microprocessor port address, for the three-axis servo motion system, it can only be realized by using complex control technology, (3) Although the amount of tin feeding can be adjusted according to the size of the solder joint of the object to be welded during welding size, but did not consider the temperature of the solder joints, resulting in inconsistent solder joints, no automatic observation and compensation for the results of spot welding, and sometimes the amount of solder on the entire curve is inconsistent, and then manual secondary repairs are used
