Description

TECHNICAL FIELD

[0001] The present application belongs to the field of special material processing equipment, and particularly relates to an ultrathin slicing device for elastic materials. BACKGROUND

[0002] Elastic materials refer to materials that can be significantly deformed under external force and return to their original state after the external force is removed, such as silicone rubber, polyurethane (PU), thermoplastic elastomer (TPE), etc. Such materials have excellent flexibility, impact resistance and fatigue resistance, and are widely used in cushioning pads, sealing rings, keys, etc., to reduce the impact of vibration and impact on precision components. Or in the medical field, such as the production of artificial organs, catheters, medical adhesive tapes, etc., which require materials to have biocompatibility and flexibility. Especially in energy and thermal management, such as elastic gaskets for heat conduction and heat dissipation used in electronic heat dissipation, filling the gap between devices and heat sinks, and improving heat conduction efficiency.

[0003] Ultrathin slicing technology can process elastic materials into extremely thin sheets (usually with a thickness of 0.05mm~1mm) to meet the needs of high-precision applications, especially in the field of heat conduction: heat-conducting ultrathin gaskets: used as heat dissipation interface materials for electronic devices (such as CPUs, GPUs, LED modules), filling small gaps and efficiently conducting heat. Its thickness needs to be adjusted according to the application scenario: ultrathin type (0.1mm~0.3mm): suitable for high-integration chips to ensure close fitting without affecting the structure design. Standard type (0.5mm~1mm): used in larger gaps or scenarios requiring higher compression, such as power battery module heat dissipation. Ultrathin elastic slices can also be used in flexible sensors, micro-seals, optical films, and other precision components.

[0004] Currently, common devices for ultrathin slicing include rotary slicing machines, frozen ultrathin slicing machines, laser cutting machines, and precision die cutting machines. For rotary slicing machines, they are suitable for medium-hardness elastic materials, have high cutting efficiency, and can be mass-produced. However, they have limited control accuracy for ultrathin slicing (<0.1mm) and are prone to produce burrs. Frozen ultrathin slicing machines can solidify materials at low temperatures and can cut extremely thin (0.05mm or less) and soft elastomers with smooth cuts. However, they have high equipment costs, require liquid nitrogen cooling, and are complex to operate. Laser cutting machines can achieve non-contact processing and are suitable for cutting complex shapes with smooth edges and no stress. However, the heat-affected zone of the processing may change the material properties, and high-power laser equipment is expensive. Finally, precision die cutting machines are suitable for mass production, have low costs, and high efficiency. However, the mold customization period is long, the precision is high, and the cost is large, which is not suitable for small batch trial production in the research and development stage.

[0005] In summary, the elastic material ultrathin slicing technology plays a key role in the field of miniaturization and high precision, especially the high requirements of the thermal pad on thickness and uniformity promote the continuous optimization of the cutting process. The selection of equipment needs to consider factors such as material properties, thickness requirements and production costs. Therefore, it is of great significance to develop a high-efficiency and safe slicing device with low cost and high precision. SUMMARY
