During the use of large rolls of tape, joints may appear as the material is consumed. These joints differ in properties from normal materials, and if not detected and processed in a timely manner, it may affect the effectiveness of subsequent operations and the consistency of the product.

Especially on automated production lines, rapid and accurate detection of tape joints is particularly important. However, due to the transparency of the tape and the insignificant difference in interface thickness, traditional sensors often struggle to perform this task.

In this issue, Xiao Ming will share with you Akusense ultrasonic principle groove sensor, which has become an ideal choice to solve this difficult problem with its super strong detection stability.

1. The high transparency property of adhesive tape

Transparent tape allows light to pass through almost unobstructed, which makes traditional sensors that rely on light obstruction or reflection (such as some photoelectric sensors) difficult to work effectively, resulting in sensors being unable to distinguish between tape interfaces and normal tape parts, leading to false or missed detections.

2. The difference in interface thickness is not significant

The difference in thickness between the interface of transparent tape and normal tape may be very small, even difficult to detect with the naked eye. This small thickness variation requires extremely high precision and sensitivity to capture

3. Complex application environments

In industrial production environments, tape may be subjected to various complex conditions such as high-speed movement, tension changes, and dust pollution. These factors may all have an impact on the detection performance of sensors.

1. Detection speed of 128m/min: Meiji wide groove sensor KUM08-0307 series, with high sensitivity and stability, can quickly detect in high-speed rotating coils.

2. Not affected by material: Regardless of the material/color/transparency of the tested object, the ultrasonic sensor can perform stable detection, even if there is dust and mist in the working environment, it will not affect it;

3. Easy to use: supports dynamic/static teaching, sensitivity adjustment

Installation and Debugging:

Install the sensor in a suitable position on the tape transmission path to ensure that it can stably emit and receive ultrasonic waves. By using the dynamic/static teaching function, the sensor is initially set to adapt to tapes of different widths and thicknesses. At the same time, the sensitivity adjustment function is used to fine tune the sensor to improve the accuracy of detection.

Signal processing:

The sensor converts the received reflected echo signal into an electrical signal and processes it through a built-in algorithm. When the tape interface is detected, the sensor will send a trigger signal to the actuator, such as the cutting device, to achieve timely processing of the tape joint.
