The WCPE200 series annular piezoelectric sensors developed and produced by Weiqin play a core role in the crimping force management solutions for crimping machines, enabling high-precision and traceable crimping processes.
Before the introduction of piezoelectric sensors, the quality control of crimping in traditional crimping machines typically faced the following issues: indirect measurement, poor accuracy, lack of real-time monitoring, absence of process data, reliance on experience for setting parameters, and no traceability.
In light of this, we will detail the crimping machine solution that incorporates annular piezoelectric sensors.
1. System Composition of the Solution
1. WCPE200 series annular piezoelectric sensor: As the “sensory organ”, it is responsible for collecting raw force signals, capable of withstanding instantaneous impact forces (pressure) of up to 20K N, while integrating a signal conditioner, which amplifies the weak charge signals output by the sensor and converts them into standard electrical signals.
2. Proximity Sensor: As the “eyes”, it prevents false strikes and misalignment through real-time detection, while also allowing for the counting of production quantities.
3. Pressure Manager: It collects and processes standard pulse signals at high speed, comparing the real-time collected waveform (measured waveform) with the reference waveform. If the difference between the two exceeds a pre-set threshold, the device will output an alarm signal, prompting the operator to check product quality.
It can connect to various system platforms, such as vision systems, upper computer systems, etc.
3. Industrial Computer/PLC and HMI: Running crimping management software for real-time data processing, analysis, judgment, display, and storage.
2. Core Advantages of the WCPE200 Series Annular Piezoelectric Sensor
High Precision and High Rigidity: The piezoelectric sensor itself has extremely high rigidity, almost not deforming under pressure, thus not affecting the precision of the crimping process; it can also provide extremely accurate force measurements, with a maximum range of 20KN, voltage sensitivity 0.26 mV/N ±10%.
Direct Measurement: It directly measures the crimping force itself, rather than indirect parameters, resulting in true and reliable outcomes.
High Frequency Response Characteristics: It can quickly respond to instantaneous changes in pressure, fully capturing the dynamic force curve of the entire crimping process, not just the peak value.
Annular Hollow Design: Very suitable for applications like crimping machines that require central space to accommodate molds, wires, and other components, easy to install, and does not interfere with existing structures.
