High-Precision 4680 Cylindrical Battery Hydraulic Crimp Sealer
1. Equipment Description
1.1 Working Principle:
The hydraulic cylinder, driven by the hydraulic station power transmission system, enables the equipment to operate intermittently. The equipment applies enormous pressure through the sliding motion of a high-precision, high-frequency guide rod guided by a copper-sleeved guide seat, pressing the battery shell and cap to the required process dimensions to achieve battery sealing.
1.2 Performance Features:
This equipment integrates electrical and mechanical systems, with the entire production process fully automated under PLC control. It features low energy consumption, low operating cost, high efficiency, high precision, easy maintenance, and a low failure rate.
2. Main Technical Components
l Airtac cylinder
l Mitsubishi electrical control system
l Upper frame touch-screen fine adjustment control
l Jiazun sensors
l MEAN WELL power supply
l Safety protection devices
l Protective guard for the upper pressing plate
l Sealing molds for first seal, second seal, and third seal — key parts made from mold steel
3. Main Technical Structure
(Seven sections — A: Hydraulic Section, B: Feeding Section, C: Pushing Section, D: Mold Closing Section, E: Upper/Lower Sealing Mold Section, F: Discharging Section, G: Electrical Section)
(The entire machine is insulated and capable of live sealing operations.)
A. Hydraulic Section
l Equipped with a hydraulic cylinder of φ100 mm bore.
l The precision hydraulic cylinder generates high pressure via hydraulic drive; positioning guide columns operate in high-performance vertical reciprocation.
l Full mold positioning ensures low noise.
l Upper mold descends at low speed (pressure unchanged), with production efficiency of approx. 20–25 PPM (adjustable via frequency converter).
l Touch screen enables manual fine adjustment, human–machine interface, intelligent control, and convenient settings.
l Copper bushings and key connections use positioning pins to ensure easy disassembly and consistent alignment.
B. Feeding Section
l Extra-long conveyor increases loading quantity, extending operator activity time and reducing labor requirements.
l A row of magnets on the base of the feeding chute keeps cells upright; feeding direction: left-hand infeed.
l Taiwan TWT variable-speed motor drives wear-resistant feeding belt for accurate automatic delivery to each station.
l Transmission system adopts German NEY bearings.
C. Pushing Section
l Proximity sensors detect cell position and transmit signals quickly.
l Single cylinder drives a U-shaped pusher block to press-fit the cell cap. Pre-sealing mold includes capping function; first, second, and third seals are completed in one cycle.
l Push height adjustment mechanism allows left–right and vertical adjustment with positioning pins; side screws adjust the clearance between moving plates to ensure vertical push motion.
l Imported guide rail under push rod, with additional sliding table for flexible adjustment of push height position.
D. Mold Closing Section
l Airtac cylinders use pneumatic pressure to drive a bi-directional mold base for cyclic mold closing, completing continuous sealing.
l Mold bases are made from oil steel, heat-treated and precision-machined for wear, corrosion, and high-temperature resistance.
l High-precision positioning prevents upper mold from descending if mold closing is incomplete, protecting lower mold.
l Spring ejector pins position cells during mold closing to secure them.
l Mold clamping location precision is improved for easy mold installation/removal.
E. Mold Section
l Upper molds for first, second, and third seals all use a third-seal style, with mold center shafts precisely fitted to tapered center holes of the mold base.
l Mold base is positioned with locating pins for easy removal without losing center alignment.
l Key working areas of molds (upper/lower) are made from mold steel, with high precision, wear resistance, corrosion resistance, and high-temperature resistance.
l High-precision mold sleeves made from mold steel; upper molds have semi-circular locking blocks for secure fastening.
l Mold usage counting function, resettable only by manual operation.
l Non-manually damaged molds have a lifespan ≥ 2 million cells.
F. Discharging Section
l Discharge mechanism automatically unloads cells into the chute using a motor-driven belt.
l Discharge direction: left-hand outfeed.
l Both loading and unloading are operated from the left side, enabling full control by a single operator, greatly reducing labor costs.
G. Electrical Section
l “Manual” mode for mold adjustment/testing; switch to “Automatic” mode once process requirements are met.
l Mitsubishi electrical program ensures precise, safe, and reliable full-process monitoring.
l Multiple sensors connected with safety interlocks; solid-state relays control solenoid valves.
l Automatic alarm for abnormal conditions; stops automatically in case of incorrect operation.
l Equipped with emergency stop for immediate shutdown.
