1. Application of solder joint counter in spot welding operation
When in use, the sensor and the normally closed switch are mounted on the welder, and integrated into an interface to facilitate the installation of the system, and the interface of the system can be connected to the normal operation.
When the operator is welding, a pulse signal is triggered. Through the acquisition of the pulse signal, the microcontroller determines the state of its operation. If the operator misses or operates for longer than the standard time, the system will report an error and send an error message to the control room over the network.
2. Welding point counter networking
Through the networking of the solder joint counter, the function of automatic detection can be more utilized.
If the on-site counter has a shutdown alarm, the corresponding station and error information will be displayed on the console. At the same time, the control room staff will feed back the information to the field engineer and quality management personnel corresponding to the station. In this way, the field engineer will know the mistakes made by his employees in the first time, and go to the on-site work station to conduct investigation and guidance.
In addition, the system can also be connected to a host computer such as a computer, and analyze the data through software to find out the probability of each station being wrong. We can analyze the workstations on the spot through the data analysis provided by the software, find out the reasons for the mistakes, improve them, and prevent mistakes more effectively.
3. The use of solder joint counters is more conducive to the implementation of workshop standardization and other work
After the solder joint counter is installed and debugged, the operator's spot welding operation time and the number of solder joints have very reasonable and clear requirements, and there are also strict requirements on the production auxiliary time such as the assembly. In this way, during the operation, the operator will not suspend his operation, which facilitates the management of the product quality of the workshop.
How to control quality is a difficult problem in welding production quality management during the welding process. Since the quality of the quality problems during the spot welding operation is very random, it is particularly difficult to find quality problems in the process. If the counter is integrated into the spot welding operation, the problem will be simplified. During the operation of the operator, record the spot welding time and the number of solder joints to determine whether his operation is correct. If abnormal operation is found, immediately report the operation to the operation and control the quality during the process. This has also changed the current situation of setting up multiple inspection points on the production line to check for the presence of missing solder joints, and more to control quality during the production process. It saves the cost of workshop quality control and improves the quality management of the workshop.
4. Other applications
This counting system is not only suitable for spot welding. By changing the sensor of the system, the sensor can also detect the number of studs welded by the stud welder. Therefore, after improvement, the system can also be applied to the stud welder. This type of counting system uses a modular design. We can integrate it into the welding machine and apply the resources of the welding machine to realize the functions of the system. In this way, the function of the welder is enriched, the welder has the function of quality control, and the welding quality of the entire automobile industry is improved.
Spot welding has a wide range of applications in the automotive industry
Spot welding has a wide range of applications in the automotive industry. Therefore, solder joint counting systems have broad application prospects.
