Advanced Arise Web Guide Sensor

Arise is an audited, leading web guiding system manufacturer in China with a professional R & D team. Arise can provide advanced web guide sensor for continuous and accurate edge position control of coil materials.

AE400 CCD Image Sensor

AE400 CCD image sensor adopts an imported CCD sensor and the lens. It can track the edges of various materials with a real-time screen display and an easy full-touch operation.

1. No need for polarity conversion.

When the coil baseline and line asymptotically or the left and right edges are reversed, there is no need to switch the polarity of the control output.

2. No need to re-adjust the gain.

The deviation of the edge from the output voltage is not affected by the width or color of the line. Therefore, once the gain of the controller is set during the test run, there is no need to re-adjust the gain.

3. Position signal hold function.

When a line leaves the field of view and when it returns, the position signal generated immediately before the line leaves the field of view is maintained and output. Therefore, when the web bending speed is fast and the line (edge) will be out of the field of view, the tracking operation will be performed.

4. The line (edge) position is displayed by LED.

The control action, even if the integral action is standard, can also be combined with the position transmitter to perform proportional action. The most suitable control action can be selected according to the machine used.

5. When the detected edge is in the center of the field of view, an LED indicator lights up.

When the device is connected to a controller with a drive lock input, in the case of intermittent lines, when an interruption is detected in the line, the drive is locked and the tracking operation is stopped until the next line appears.

A100 Infrared Edge Sensor For Reading Web Edge

Arise A100 infrared edge sensors are specifically designed to read the edge of webs which has the features of sound-transparent, thick weaves and non-transparent. The web guide sensor uses an infrared LED as the light source. The light is reflected through the material and is then recorded by a CCD line. The CCD elements illuminated in this way in the edge sensor issue a higher signal level. The signal level can be converted into an output value proportional to the web edge position.

As the demand for electric vehicles (EVs) and energy storage solutions surges, the efficiency of lithium-ion battery assembly lines plays a crucial role in determining the success of battery manufacturers. A well-optimized assembly line ensures high precision, consistency, and cost-effectiveness. But how does the process work? Let’s dive into the key stages of a lithium-ion battery assembly line.

Cell Grading: The Foundation of Excellence

Cell grading is a crucial first step in the process when each battery cell is carefully examined to ascertain its performance parameters. To produce a thorough "report card" for every cell, capacity, and internal resistance are carefully examined. This methodical procedure guarantees uniformity and groups cells according to their performance attributes, establishing the groundwork for the best possible utilization of a battery pack.

Cell Sorting: Precision in Pairing

After grading, cells are sorted based on their specifications, optimizing the performance of the final battery pack. By ensuring that the batteries in a pack are precisely matched, this precision matching maximizes performance and prolongs battery life. To fully utilize each cell's potential within the battery pack's overall power, this phase must be carefully planned.

OCV Testing Machines

Open Circuit Voltage (OCV) testing machines measure the voltage of cells to ensure they meet the required standards before assembly.

CCD Polarity Tester

This equipment is used for precise alignment and assembly of battery components, enhancing the overall efficiency of the production process.

BMS Testing: The Guardian of Performance

At the heart of the battery pack lies the Battery Management System (BMS), serving as its vigilant guardian. Before integration, the BMS undergoes rigorous testing to validate its functionality and its ability to effectively communicate with the individual cells. This crucial step ensures that the BMS is equipped to monitor and regulate the health and performance of the battery pack with unwavering precision.

Cell Welding: Where Precision Meets Connectivity

As the testing cells await their transformation into a unified force, the delicate process of cell welding takes center stage. Automated robotic arms execute this task with precision, forging strong and reliable electrical connections between the cells. The seamless integration achieved through cell welding forms the foundational framework for the battery pack, ensuring its resilience and efficiency.

Battery Pack Testing or Aging: Trials of Endurance

The culmination of the assembly line journey leads to the final stage – rigorous testing of the complete battery pack. Depending on its intended application, this phase may encompass charging/discharging cycles to simulate real-world usage or accelerated aging tests to evaluate long-term performance and safety. Through these trials of endurance, the battery pack's resilience and reliability are put to the test, ensuring its readiness for the demands of modern life.
