Select welding technical parameters

The working principle of

TRJ-401 Plus Welding process：

Feed plate → select position spray flux → select position weld → out plate

The whole system is a closed loop processing system.

Closed loop processing control

●Feed plate → spray → preheat → welding → out plate

Description of welding characteristics

●Range of application - teljia select welding can be convenient and factory automation production line together, and has a number of extended functions, can be over the fixture or directly welding a variety of mixed PCB board.

●Suitable for a wide range of applications - starting with the design of high performance nozzles of selected welding systems with a special material that accurately and stably ejects various tin wave heights, thus improving the ability to continuously repeat welding in limited space or too close to parts. The welding pump, propeller, lifter, robot technology, nitrogen transportation and temperature control technology, together with our unique crest nozzle, make the system tin welding performance of the cream, high precision, less defective products.

●Excellent temperature control capability in the use site - nitrogen temperature control performance is good, because it USES the PID temperature control principle (0-400 degrees), nitrogen is used for welding wave crest inerting and protection. This unique nitrogen direct heat system heats the crest of the wave. Allows the operator to choose whether to increase or decrease the temperature.

●Closed loop servomotor = high accuracy, repeatability, high welding quality - the system USES the most accurate and advanced robotic control technology - closed loop servomotor. A server is an intelligent motor that knows where it is and maintains perfect repeatability. Ball screw and linear guide guide, accurate positioning, low noise, smooth movement.

Motion control system

●Powerful control - the system's platform running, stopping, moving speed, and many other attributes are very easy to control. The motion speed, temperature parameters, product count, height correction of wave crest and automatic width adjustment of guide rail can be saved in the touch screen.

●Both systems use the most accurate and advanced robotic control technology - the closed-loop server. A server is an intelligent motor that knows where it is and maintains perfect repeatability.

●Ball screw and linear guide guide, accurate positioning, low noise, smooth movement.

cam conductor Programming software

●The system is easy to program - industrial computer system offline programming software has an elegant user interface and very fast programming speed. In just a few minutes, programmers can use imported scanned images or Gerber to convert images, select solder joints, configure nozzles, and form a selective soldering system.

●Starting point, welding time, moving speed, air travel speed, Z axis height and pump migration parameters can be edited.

Pewter height detection system

●Accuracy test of tin spraying height:

A titanium alloy test plate is installed on the side of the orbit, connected with a positive voltage, and its coordinates relative to the origin are set in the system setting in advance. After the spray interval passes some products (adjustable), it will automatically move to the position of the test probe. Meanwhile, the system will gradually increase the speed of the motor applied to the wave peak, so that the spout tin wave will contact the test probe and the positive voltage will be connected. According to the measured results, the system automatically modifiers and controls the offset to achieve the purpose of highly stable tin wave.

Spray solder monitoring system

●Spray; During the welding process, the monitor camera is displayed on the screen in real time to facilitate the understanding of the real-time spray and welding situation.

●Teljia special video software support can take photos, recording function.
