The Integrated Application Of Electric Soldering Line Filter

The cavity filter is one of the important components of the communication base station,and the welding quality of the cavity filter has a decisive effect on the quality of the whole product.How to use robots in a small space to complete the welding tasks of many different specifications of solder joints,and can be compatible with similar models of the cavity filter welding,integrated development of the welding robot to improve the efficiency of the robot and the production efficiency of the product Have a guiding significance.The internal structure of the cavity filter is more complex,but the basic structure is the same.First,according to the requirements of the process and the distribution of solder joints,the solder joints are divided and planned,the design of the 1/4 wavelength line welding,two front cavity welding,the reverse cavity welding four soldering robot workstations.Through the program to determine,decision to adopt the Beijing AETECH Six-axis robot.Through the software simulation and the actual welding operation,the robot end fixture and the shape of the tip are determined.Second,to solve the product in the automated production line in the transmission positioning problem According to the characteristics of the body structure,the use of five cylinders in three directions on the flow of the tray positioning to ensure that the accuracy of each positioning control in ±0.02.In the tray design of the corresponding positioning hole,the positioning pin to complete the product positioning,for different types of products.The I/O communication mode is used to establish the information exchange between the Robot Teaching device and the Wire Feeding device.In the teaching device through the control command to control the output of each cut off the completion of the wire feeding mode selection,wire,polished tin and other actions control.At the same time,using the relay output form,through the control of the solenoid valve on and off to complete the end control.Robot's Live Teach By manually moving the robot to the right position,record the robot's best welding coordinates.The design of the controller is divided into the host computer and the next machine,the host computer to complete the monitoring of the various workstations in the control,the next machine to complete the production process control.Through a large number of welding experiments on the workstation problems to improve and optimize to ensure the quality of the solder joints to improve the product pass rate.The entire production line stage completion of the filter production tasks,in the trial run,very good.All the welding points to test and check,in addition to a few points of welding failure,other solder joints fully meet the welding requirements.This production line for the domestic cavity of the automated production filter opened up a new chapter,but also guide the direction,especially the welding workstations,the future development and design of the soldering robot has a vane role.
