Automatic Pouch Cell Case Forming Machine

Automatic Pouch Cell Case Forming Machine

1. Equipment Overview

1.1 Equipment Function and Operating Principle

– Equipment Function:

1.1.1 Servo motor-driven manipulator for material feeding, with adjustable feeding length up to 240 mm;

1.1.2 Cutter movement controlled by laser sensor and servo drive, ensuring cutting precision within ±0.15 mm;

1.1.3 All machine actions are controlled by PLC and realized via touchscreen HMI.

– Operating Principle:

A speed-regulating motor drives the air shaft to unwind the material, with PLC-controlled servo stamping, and servo motor-driven manipulator for material pulling.

1.2 Equipment Operation Process

1.2.1 The feeding manipulator clamps the material and transfers it to the target position according to the preset distance;

1.2.2 Upon reaching the target position, the booster cylinder drives the upper mold to close and maintain pressure. The lower servo motor moves upward, pushing the punch to perform deep drawing;

1.2.3 After forming, the punch retracts, and the upper mold lifts under servo control;

1.2.4 The motor-driven transfer system positions the material at a fixed distance;

1.2.5 Once in position, the cutter moves to the cutting location. The cylinder lowers the cutter to perform trimming, ensuring sealing precision;

1.2.6 The transfer mechanism resets and the next cycle begins.

1.3 Overall Structure

Machine Dimensions: L 2020 mm × W 740 mm × H 1980 mm (for reference only)

1.4 Main Components (with diagrams)

1.4.1 Feeding Section

1. Floating roller tension device; material guide rollers made of plastic steel

2. Automatic fiber optic web guiding system integrated with the feeding mechanism

3. Unwinding driven by speed-adjustable motor; cantilever-type air shaft for material roll fixing

1.4.2 Stamping Section

1. Power Part: The upper mold adopts a booster cylinder-driven form; the lower mold adopts a servo motor-driven form.

2. During case punching, the motion is driven by a booster cylinder. The control software is compatible with two-step stamping functions. The servo motor on the upper mold ensures at least 40mm of effective stroke and ensures that it meets the power requirements for the maximum product size defined in the technical specifications (over 750W). The servo motor is equipped with the corresponding reducer and coupling. The lifting platform is guided by ball guide posts to ensure stable vertical movement.
The working surface of the material transfer mechanism and the height of the mold mounting base plate: 15-50mm.

3. The stamping part of the equipment (mold position) is equipped with safety light curtains on the front and rear doors, ensuring that there are no blind spots in the safety light curtains to guarantee the safety of operators. A door switch is installed on each front and rear door of the middle section of the equipment to ensure personnel safety.

4. The upper mold is connected using an L450mm × W390mm × T40mm 45# steel plate, with four sets of Ø40mm guide posts and linear bearings.

1.4.3 Pulling Section

1. Servo motor drives the pulling unit with edge-guided alignment; travel is adjustable, travel range ≥350 mm

2. Material press mechanism installed in front of pulling section

3. Material clamping is achieved by an independent cylinder; clamping blocks are made of anti-slip material

1.4.4 Cutting Mechanism

1. Cutter up-down motion guided by guide pillars and bushings

2. Distance between upper and lower cutters after reset: ≥60 mm

3. The cutting assembly is position adjustable, guided by a rail; travel range ≥200 mm, effective blade width ≥335 mm

4. After pulling, the cutter moves right to a fixed-length cutting position to trim the end of the product, then automatically moves to the high point of the previous foil cavity. After detecting the cavity, the cutter moves a fixed length to cut the waste, ensuring sealing position accuracy

1.4.5 Frame Structure

1. Upper frame made of standard aluminum profile, lower frame made of 60×60 mm square steel tubes with 4 mm thickness, welded and painted

2. All protective doors made of sheet metal (excluding feeding side); top doors include viewing windows; each door fitted with safety sensor; sheet metal thickness ≥1.5 mm

3. All exhaust ports of solenoid valves and manifold blocks are fitted with resin mufflers

4. Noise reduction treatment for all air pipes and cable entry/exit points

5. Noise level of all machine sections: ≤80 dB

1.4.6 Control Section

1. 65536-color true-color touchscreen

2. HMI must be intuitive and user-friendly; buttons sized to prevent accidental double-press

3. Hardware buttons on the panel: Power ON/OFF, Start, Stop (latching), Emergency Stop

4. All stations accessible manually from HMI, each with single-function interface; grouped actions under same screen, no page turning required

5. HMI must display cumulative and shift-based Pocket forming and cutting quantities, with reset function

6. Complete fault alarm and self-diagnosis functions required; names of components in alarm messages must match HMI labels exactly

7. In manual mode, interlocking logic must be in place between interdependent actions of each functional unit
