With the continuous advancement of industrial automation technology, the demand for high-precision remote measurement in the manufacturing industry is increasing. Especially in industries such as lithium battery production, precision machining, and automotive manufacturing, the precise grasping and positioning of robotic arms have become key factors affecting production efficiency and product quality.

Therefore, the market urgently needs a sensor solution that can monitor and accurately control the distance between the robotic arm and the battery surface in real time.

To meet this market demand, industrial sensor technology continues to innovate, among which laser displacement sensors with large range and micrometer level accuracy have become the preferred choice for many industrial application scenarios.

On the lithium-ion battery automation production line, the robotic suction cup needs to accurately suck up the battery and move it to the next process. In order to ensure that the robotic arm can properly lift the battery, sensors need to be installed to obtain Z-axis height data of the robotic arm and detect the height of the robotic arm from the battery surface.

1. There should not be too much gap or excessive fit between the suction cup of the robotic arm and the battery pack

2. The sensor needs to be installed on the robotic arm to follow the back and forth movement of the robotic arm

3. The height of the sensor from the surface of the battery pack is about 390mm

Difficulty analysis:

1. High precision requirements: There should not be too much gap or excessive fit between the suction cup of the robotic arm and the battery pack, so high-precision sensors are needed to detect the distance.

2. Dynamic measurement: Sensors need to follow the back and forth movement of the robotic arm, so they need to have stability and reliability.

1. Large scale requirements: Due to the need for robotic arms to move within a certain range, sensors need to have sufficient range to meet the requirements.

Select the MLD21-500N-485 model, which has the following characteristics:

⭐  High precision: Linear accuracy can reach up to± 0.3% can ensure precise distance control between the suction cup of the robotic arm and the battery pack.

⭐ Large range: The measuring range can reach 300~700mm, meeting the measurement needs of the robotic arm at different positions.

⭐  485 communication mode: Supports 485 communication mode, can exchange information with the upper computer, and achieve real-time monitoring and processing of data.

⭐ Good stability: Using CMOS photosensitive elements and laser triangulation principles, high-precision detection is achieved. At the same time, the sensor has stability and reliability, and can adapt to dynamic measurement environments.
