Automatic Cylindrical Battery Hydraulic Sealing Crimping Machine

Automatic Cylindrical Battery Hydraulic Sealing Crimping Machine

1. Equipment Description

1.1 Working Principle

The hydraulic cylinder, driven by the hydraulic station power transmission device, enables intermittent motion. Using a copper-bushed guide seat in combination with high-precision high-frequency guide rods, the machine generates substantial pressure to press the battery case and cap to the process-required dimensions, achieving the sealing purpose.

1.2 Performance Features

The entire machine integrates electrical and mechanical systems, with production fully automated under PLC control. It offers low energy consumption, low cost, high efficiency, high precision, easy maintenance, and low failure rate.

2. Main Technical Specifications

3. Main Components

A. Hydraulic Section

- A hydraulically driven precision cylinder produces substantial sealing pressure. 

- Positioning guide pillars move vertically with high performance. 

- Eight copper bushings ensure accurate positioning and wear resistance. 

- Mold positioning is maintained throughout the process, with low noise. 

- Touch screen for manual fine-tuning, HMI intelligent control, and easy settings.

B. Feeding Section

l Extra-long conveyor increases loading capacity, reduces operator workload.

l Transmission uses German NEY bearings.

l Taiwan TWT adjustable-speed motor drives wear-resistant feeding belt, ensuring accurate and safe material feed.

C. Pushing Section

l Intelligent sensors detect battery position and transmit signals quickly.

l Dual-axis positioning with single-cylinder U-shaped pusher block to pre-press battery caps.

l Pre-sealing mold integrates capping function; pre-sealing, second, and third sealing completed in one cycle.

D. Molding Section

- An Airtac cylinder drives the bidirectional mold base for cyclic sealing, accomplishing the third seal. 

- The mold base is crafted from oil steel and heat-treated to achieve wear resistance, corrosion resistance, and high-temperature resistance. 

- Optical fiber positioning avoids misaligned pressing; an automatic alarm is triggered if the position is incorrect. 

- Sealing molds undergo special vacuum treatment and are made of imported high-quality materials. 

- Under normal operation, the mold lifespan exceeds 600,000 cycles. - The third sealing mold is equipped with a usage counter (reset manually only).

E. Hydraulic Station

l Equipped with 5 MPa hydraulic station and 80 mm diameter hydraulic cylinder for sealing pressure.

F. Discharging Section

l Automatic unloading mechanism transfers finished cells to discharge chute.

l Loading and unloading on the same side for single-operator operation, reducing labor costs.

G. Electrical System

l Manual mode for mold adjustment/testing before switching to automatic operation.

l Mitsubishi PLC program monitors the entire process.

l Multiple sensors, safety light curtains, automatic alarms, and emergency stop function.
