Lithium Ion Battery Production Line Automatic production line for pull dry battery plate

3.5.Main components of equipment

2.3.5.1 Rewinding system: It is composed of motor, turntable, proximity switch and so on. Its structure is simple and practical. The Three-lobe support can be retracted and retracted at the same time. The motor can be automatically rewinded by proximity switch. Maximum diameter of unwinding 450mm.

2.3.5.2, Storage box assembly: Manually push the turnover barrel to the feeding position, the hydraulic system automatically lifts the turnover barrel, connects the interface, and the high viscosity pump automatically pours the slurry into the oblique hopper. After the level sensor detects the position, the conveying pump stops and the steel belt passes through the slurry.

2.3.5.3. Precision scraping system: This mechanism is mainly composed of scraper mechanism, steel belt leveling mechanism, blank mechanism, base and other systems.

2.3.5.3.1 Scraper plate mechanism: the mechanism consists of scraper board, scraper board straightness 0.005mm.

2.3.5.3.2 Blank Retaining Mechanism: The mechanism is mainly composed of scraper and pressure plate. According to the need, the size of scraper is 23.5 mm and 31 mm, two width sizes.

2.3.5.3.3 Steel strip leveling mechanism: The mechanism is installed under the scraper plate to shape and leveling the steel strip to ensure that the steel strip is leveled during scraping.

2.3.5.3.4 Base, the mechanism is mainly composed of base plate and positioning pin. The positioning pin ensures that the steel strip is easy to wear, load and unload, and the operation is simple.

2.3.5.4, Drying component: It is composed of structural steel, structural steel plate, rigid aluminium silicate fiber insulation material, heating pipe, infrared device, temperature controller, big wheel and so on. Each section is temperature controlled independently to ensure quality.

2.3.5.5, Corrective component: the servo motor, screw rod mechanism, laser inductor and roller constitute a good corrective effect.

In addition to the danger of artificial altitude correction operation. When the laser sensor senses the steel strip offset, the servo motor rotates.

The screw drives the axle of the roller to be offset so that the axes of the roller are parallel to the axes of the wheel, so that the steel strip can enter the assembly smoothly and the steel can be reduced.

It is easy to deform at critical temperature.

2.3.5.7, Automatic slurry conveying system: manually push the turnover bucket into the automatic lift truck, lock the buckle and turn the turnover.

The bucket is fixed, the lift truck rises, and the interface between the bucket barrel joint and the high viscosity pump pipeline is manually butted and locked. Pass in slurry tank

When the sensor detects that the slurry is below the set liquid level, it automatically starts the high viscosity pump, automatically transports the slurry, and reaches the set liquid level.

Sensor induction, high viscosity pump operation automatically transfer slurry to slurry tank.

Working principle and structure of high viscosity pump

2.3.5.7.1 Working Principle of High Viscosity Pump: The drive gear (outer rotor) with inner teeth drives the inner rotor to rotate in the closed pump body in the same direction, and the crescent plate of the pump body and front cover separates the suction port from the discharge port. When rotating, a negative pressure is formed at the suction port, and the liquid is sucked in. The rotor takes the liquid to the discharge port and discharges the pump body under pressure to complete the liquid transportation.

2.3.5.7.2 High Viscosity Pump Structure: High Viscosity Pump mainly consists of internal and external rotor, shaft, pump body, front cover, bracket, seal, bearing and so on. There are two types of seal: mechanical seal and packing seal. For medium with high temperature, high viscosity and strong corrosiveness, packing seal is selected. When transporting crystalline materials by high viscosity pumps, heat preservation jackets can be designed on the front cover and pump body. Steam or heat conducting oil can be used for heat preservation and melting during operation.

2.3.5.7.3 The main features of the internal viscous high viscosity pump are:

2.3.5.7.3.1 Pressure and flow pulsation are small (output pressure: 0 ~ 2.0MPa).

2.3.5.7.3.2 Self priming performance (suction pressure: vacuum -0.05 ~ -0.08MPa)

2.3.5.7.3.3 The viscosity range of conveying medium is large (1.0Cst-300000Cst).

2.3.5.7.3.4 Pump inlet and outlet can be turned and piping is convenient.

2.3.5.7.3.5 The shell is equipped with a jacket housing to realize the heating and insulation of the pump body (less than 250 degrees Celsius).

2.3.5.7.3.6 Stainless steel can be used to transport corrosive media.

2.3.5.7.3.7Packingsealormechanicalsealcaused.

2.5.8,Cache system: The power-free caching mechanism is adopted. When the steel strip is used up and needs to be replaced, the caching mechanism functions and is replaced manually to realize uninterrupted production.

2.3.5.7.3,Functional description

2.3.5.7.3.1 Main control interface and five line chart control instructions (schematic, final delivery software).

Explanation: In addition to the grey quality band of the midline and upper and lower limits of the thickness specifications determined by the product process, a preset alarm line (red) is added to form a 5-line control chart of the thickness range.

2.3.5.7.3.2 Fixed point measurement and edge detail inspection (schematic diagram, with actual delivery software as the criterion).

Description: Fixed-point measurement means that the C frame is fixed at a certain position and the polar plate is measured by periodic line scanning in the Y-axis direction, i.e. the Y-axis longitudinal scanning thickness measurement.

2.3.5.7.3.3 SPC analysis of data storage and volumedata

Description: Data is saved in a thickness data folder with a minimum resolution of 1 mm polar width; data is saved in the data folder of the PC hard disk directory and saved in Excel documentformat.

Description: SPC analysis software statistical samples for each volume of a single cycle (one scan) mean or a longitudinal interval range of a single cycle mean.

2.3.5.7.3.4 Other main functions:

The system calibration is a set of automatic actuators. When the C-frame is at the starting position (or the calibration position), the standard thickness block automatically calibrates the laser measuring system. This automatic calibration process will solve the small size change of the C-frame caused by the change of ambient temperature and structural stress.

SLG350 can write specified data to specified registers in socket form or MC protocol through Ethernet interface.

The system provides automatic overshoot alarm function, sound and light alarm and alarm condition is optional.

The system has the function of real-time recording work of length/temperature/humidity of auto-process pole reel, which greatly facilitates users'application of traceability of production process data. The length encoder is installed on the side of the guide roll to measure the length of the strip. A group of temperature and humidity sensors are installed in the C frame to synchronously measure and record the environmental temperature and humidity during the process.

The system is equipped with automatic gas blowing device, automatic blowing blowing calibration film and lower laser lens glass falling ash.

The control system adopts two-level design, PLC servo motion control and PC working alone, which can display and save massive production thickness data, facilitate inquiry and tracing, and facilitate the use of network data links to access database and other information management systems (such as MES system).
