Today, Wuxi Rihuan Sensing Technology Co., Ltd. will introduce the solution for us. These sensors assist the laminating machine and ensure the safety of lithium battery intelligent manufacturing.
The laminating machine, as a crucial equipment in the production process of lithium batteries, its performance and accuracy directly affect the quality and production efficiency of lithium batteries. Therefore, Rihuan Sensing is committed to integrating advanced sensing technology with in-depth knowledge of the lithium battery industry, providing comprehensive and customized sensor solutions for lithium battery manufacturing enterprises.
Scene Requirement 1: Monitoring of leftover materials during diaphragm feeding process
Solution:
Laser displacement sensor RS series
Application scenario:
On the laminating machine equipment, it is necessary to inspect the remaining lithium battery separators. When the separator roll is about to run out, the sensor sends a feedback signal to the equipment to respond and alert the operator to replace the roll in time.
Technical advantages:
✅ Available in three detection distances: short, medium, and long. Small in size, with small light spots and high precision.
✅ Equipped with single output for digital signals, dual output for digital and analog signals, and RS485 communication output functions.
✅ Multiple functions and various detection modes, suitable for more application scenarios.
✅ Aluminum alloy casing, more durable. Film buttons for easier operation.
Scene requirement two: mechanism limit position control
Solution:
Slot-type photoelectric sensor RH45 series
Application scenario:
In the winding machines and laminating machines of the lithium battery industry, servo motors are often used for positioning control to facilitate position correction. A large number of sensors need to be selected and widely applied to multiple points within the machine to control the origin and extreme positions of the mechanism modules, as well as the position of the rollers.
Technical advantages:
✅ Built-in independently developed photoelectric chips, featuring powerful functions, small size, high anti-interference ability, and high stability
✅ Multiple model options, with high-speed response
Scene requirement 3: Detecting the extension and contraction state of the cylinder
Solution:
Application scenario:
Detect the expansion and contraction state of the cylinder, determine whether the cylinder is operating normally, and ensure the stability of the equipment during operation.
Technical advantages:
✅ Compact size, available for both small and large cylinders, multiple specifications for quick installation
✅ High sensitivity magnetoresistance, with a repeatability accuracy of 0.001mm
✅ Integrated injection molding, sturdy structure, and elegant appearance
Scene requirement 4: Label color detection
Solution:
High-end color sensor series REB-W50
Application scenario:
In the winding machines and laminating machines of the lithium battery industry, it is often necessary to check whether there is adhesive tape above the electrode sheet / separator material, so as to proceed with the subsequent cutting or winding.
Technical advantages:
✅ Utilizing the Dayring REB-W500 series, it can accurately identify the color output signal of the tape.
✅ Excellent anti-shake performance, with background suppression function. Even if the tape experiences shaking due to unstable tension, it can still stably detect the tape color and output it.
Scene requirement five: Monitoring of leftover material on the electrode sheet.
Solution:
Ultra-thin photoelectric sensor REZ series
Application scenario:
Detect whether there are electrodes in the electrode tray. When the electrode material is exhausted, the sensor will promptly send a signal to drive the equipment to replenish the material.
Technical advantages:
✅ Utilize the REZ series of ultra-thin photoelectric sensors from Dayuan. The ultra-thin design effectively addresses the "space anxiety" issue of the equipment.
✅ Comes with built-in positioning holes, facilitating installation.
✅ With a protection level of IP65 and superior mechanical performance.
Scene requirement six: Protect the safety of operators.
Solution:
Standard type safety beam sensor RHS series
Application scenario:
Protect the safety of operators. When a person's hand enters the working area, the internal mechanical hand of the equipment will immediately stop operating.
Technical Advantages:
✅ Utilizing the standard type safety light curtain sensor from the Dayring RHS series, installed on both sides of the door frame. When someone's arm enters, the machine detects it immediately and stops.
✅ Compact structure design, with better shock resistance, longer service life, an economical model, with a more affordable price, suitable for safety protection in equipment areas.
