Nut weld detection system (projection weld nut error prevention detector) uses a programmable controller as the control core. The welding machine pressurizes the cylinder to press the lower electrode positioning pin to determine the position to ensure the welding of the projection weld nut. Correctness, and at the same time, control the normal operation of the nut projection welding machine, electrode management, and prevention of missing or excessive welding by detecting the external input signal. At the same time, it is convenient for the factory management personnel to manage the current work, to prevent missing or excessive welding, thereby improving work efficiency and ensuring product quality. The main functions are as follows:
- Press the pressure cylinder of the welding machine to press down the positioning pin of the lower electrode to determine whether the position of the nut is correct or not. When detecting, the current position is first read out and compared with the allowed position. When OK, the welding is energized, NG When forced to disconnect the pressurized cylinder without energizing, and issue an alarm indication (Type B)
- With welding counting function, including projection welding nut number, electrode exchange, production number, positioning pin life counting. The counting signal can be provided by proximity switch, photoelectric switch, travel switch, micro switch or relay, etc., the distance is not limited.
- With the function of adding dots.
- The welding parameter table and the display of the names of parts and components are attached to the interface to facilitate the confirmation of welding conditions when changing the workpiece.
- It has the optional function of counting reset. When the welding count reaches the set value, manual reset or automatic reset can be selected. If automatic reset is selected, the automatic reset time can be set.
- It has the optional function of resetting when the nut welding is abnormal. When the welding detects an abnormality, manual reset or automatic reset can be selected. If automatic reset is selected, the automatic reset time can be set.
