Problems solved by technology

However, timing interruption will interrupt the sequential programming mode, and the program structure is more complex and programming is more difficult; the timing polling method can guarantee the sequential programming mode, but there is always a certain time interval between each polling, PLC Being idle during this time interval is not conducive to faster data acquisition and control

Embodiment Construction

[0056] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

[0057] The battery tab ultrasonic welding system mainly includes four subsystems: ultrasonic generator, PLC electrical control module, welding machine frame, and human-machine interface (HMI). The working modes of the battery tab ultrasonic welding system are mainly divided into time mode and energy mode. The time mode uses a fixed length of time set value as the input of the ultrasonic generator to realize the welding function of the same length of time; the energy mode is a fixed size. The energy setting value of the ultrasonic ...

Abstract

The embodiment of the invention discloses a welding control method and a welding system. The welding control method includes: detecting the running state of the welding machine; if the welding machine is in the welding state and running in the energy mode, then obtaining the first power sampling signal for the welding machine; obtaining the count value of the timer, and obtaining the count value Resetting the timer afterward to control the timer to count again, wherein the count value is used as the welding duration of the welding machine in the last welding stage; obtain the second power sampling signal for the welding machine; based on the first power sampling signal, the second power Sampling signal and welding time to determine the energy increment generated by the welding machine in the previous welding stage; control the operating state of the welding machine based on the energy increment. The controller can automatically calculate the accumulated welding energy in the welding process according to the obtained parameters, and there is no waiting process, which realizes the uninterrupted welding process while simplifying the program structure, and improves the welding efficiency of the entire welding system. efficiency.

Description

technical field [0001] Embodiments of the present invention relate to welding technology, and in particular, to a welding control method and a welding system. Background technique [0002] The battery tab ultrasonic welding system mainly includes four subsystems: ultrasonic generator, PLC electrical control module, welding machine frame, and human-machine interface (HMI). The PLC electrical control module controls the welding energy of the welding system according to the power analog quantity and the operation control signal provided by the ultrasonic generator. [0003] To achieve energy control, it is necessary to sample the power analog quantity of the ultrasonic generator to calculate the corresponding energy value. At present, sampling at fixed time intervals is usually adopted, and in PLC, the sampling is interrupted at regular intervals by a timer or by means of timed polling. However, the timing interrupt will interrupt the sequential programming mode, and the prog...
