I. Project: Solder wire on PCB
In the line, workers have to perform spot welding manually, so the following situation occurs:
The time to complete a welding spot is too long
Does not meet productivity requirements
The welding points are quite bad, do not meet aesthetic needs.
The customer gave the problem and VULETECH based on the provided data, designed and manufactured an automatic double-head welding system, reducing labor in spot welding, optimizing productivity and saving time.
II. Structure of the electronic circuit board two-headed welding machine:
The two-headed welding robot of electronic circuit boards is integrated by VULETECH from Scada Adtech AR4125 Robot, Hunter 372 welding equipment, circuit board conveyor. In addition, the product is equipped with a Pizzato safety device.
1. Scara Adtech AR4215 Robot:
Adtech AR4215 Scara 4-Axis Robot is made up of Robot body and controller (hardware and software). The robot is made up of a Panasonic Servo motor and a Japanese Harmoni Drive gearbox. Scara Adtech AR4215 robot for high performance is often applied in the automotive industry, semiconductor industry and electronics industry.
2. Hunter 372 welding equipment:
Hunter 372 welding equipment includes welding source, control system, welding gun wire feeder to help:
Reduce the problem of splashing out during welding
Helps improve weld quality
Quick heat recovery
Feeding speed, volume, duration and duration can be adjusted
Automatic and manual feeding mode.
