This large-format CCD digital cutting machine integrates a high-resolution camera and projector to form an intelligent, efficient, and high-precision cutting system. It can accurately identify complex patterns, printed graphics, and material textures, providing reliable visual data for precise cutting. This system is particularly suitable for industries that demand high material utilization, product quality, and automation, such as leather goods, footwear, apparel, composite materials, and high-end packaging.

The two core functions of large-format CCD digital cutting machines are:

Large-format CCD Cameras

Large-format CCD digital cameras can capture a wide field of view of the material in a single shot, covering the entire workbench or large-format feeding area. Their core function is intelligent defect detection, utilizing high-resolution imaging and advanced vision algorithms to automatically identify surface defects such as stains, damage, color inconsistencies, wrinkles, or natural imperfections (such as scars or insect bites on leather).

Once defects are detected, the system marks these areas, and the intelligent nesting software automatically avoids these areas during the nesting process, maximizing the utilization of defect-free material. For irregularly shaped materials such as natural leather or rolled edges, a large CCD camera can accurately track their contours, allowing for more precise and optimized nesting based on the actual shape.

Projector

The projector can display cutting paths, nesting layouts, and defect areas directly onto the material in real time. This allows operators to visually see the cutting preview, part positions, and areas to avoid due to defects. When a large CCD camera detects a defect, the projector accurately outlines the defect on the material surface.

This visual feedback enables operators to easily make manual adjustments to avoid defects or fine-tune the nesting layout, resulting in optimal human-machine collaboration. The result is more precise and efficient adjustments, ensuring accurate material cutting.

Differences between large and small CCDs in their practical application in digital cutting machines:

Differences in Installation Location and Structure

Large CCDs are mounted above the machine's gantry and typically use high-resolution industrial cameras or digital SLR cameras. They provide a wide field of view, allowing for the capture of the entire worktable or large-format materials in a single shot.

Small CCDs are mounted near the cutting head; they are smaller in size and have a limited field of view, primarily used for capturing specific local areas or registration marks.

Different Recognition Capabilities

Large CCDs can capture images of the entire material area, enabling automatic recognition of overall contours, defect detection, and automatic material placement. They are ideal for automated cutting of large-format, multi-pattern, or irregularly shaped materials.

Small CCDs are primarily used for identifying and locating print registration marks and QR codes. They are suitable for precise positioning of single graphics or small areas. They are commonly used for cutting labels and stickers on long rolls of material.

Different Application Functions

Large CCDs support automatic defect detection and contour recognition. They are suitable for automated mass production of complex graphics.

Small CCDs support automatic QR code reading and registration mark recognition, enabling automatic file retrieval and precise positioning. They are ideal for high-precision, large-format, and mixed-layout material cutting.

Differences in Automation and Efficiency

Large CCDs can capture a large area of material in a single shot, automatically completing the identification, layout, and cutting of multiple sheets. This significantly improves production efficiency and is suitable for large-volume, unmanned operations.

Small CCDs require point-by-point identification or require the camera to move with the cutting head. They are suitable for diverse or high-precision production needs.

Differences in File Import

Large CCDs do not require importing graphic files.

Small CCDs require graphic files to be imported in advance.

Different Application Scenarios

Large CCDs are used for automated cutting of large-format materials in industries such as trademarks, clothing, printing, and advertising. They support defect detection and intelligent layout.

Small CCDs are used for high-precision positioning and cutting of long-format roll materials such as labels, stickers, and printed materials.

Detailed structure of a large-scale CCD digital cutting machine:

air gun

This portable air gun, equipped with a fixed bracket for easy access, is primarily used to clean away large amounts of dust, debris, waste, and even fine fibers generated during the cutting of various materials such as cardboard, foam, fabric, leather, and composite materials. It can quickly and effectively blow away residue from the cutting table, ensuring a clean and tidy surface for the next cutting operation.

The air gun can also remove dust from tools such as vibrating knives and milling cutters, or from modules such as creasing wheels and punching tools. Its long, slender nozzle allows it to reach into the crevices and corners of the machine, enabling targeted cleaning and maintenance of hard-to-reach areas.

Aerospace-Grade Aluminum Beam

The beam is made of aerospace-grade aluminum alloy, treated with special alloy processing and structural optimization. This material offers advantages such as light weight, strong bending and torsional resistance, corrosion resistance, and long service life. Its reduced weight enables higher acceleration, faster cutting speeds, and lower energy consumption.

High-precision linear guides and racks are used on both sides of the beam, ensuring smooth and precise transmission.  Combined with the servo system, the X-axis movement is fast and accurate, making it ideal for rapid positioning and high-speed cutting in large-format designs.

Infrared Safety Sensor

Infrared safety sensors are primarily used for real-time detection of foreign objects. They typically consist of an infrared emitter located on one side of the beam and a receiver on the other side. By creating an invisible light curtain in front of the cutting area, the sensor can instantly detect hands, body parts, or any objects entering the sensing zone.

Once triggered, the system immediately sounds an alarm and stops the cutting operation to prevent injuries caused by the high-speed movement of the blade, thus maximizing the safety of operators and surrounding personnel. In addition to protecting personnel safety, the light curtain also prevents large or hard objects from accidentally entering the cutting area, avoiding potential damage to the cutting tool or the machine itself.

Metal Gear

The large-scale CCD digital cutting machine utilizes high-strength metal helical gears, paired with precision racks, to drive the cutting head for high-speed and high-precision rotation along the X or Y axis.  This transmission system is highly efficient and precise, with excellent wear resistance and strong load-bearing capacity, ensuring long-term industrial durability.

Unlike spur gears with sudden engagement, helical gears engage gradually, resulting in smoother transmission and reduced impact and vibration. This design significantly lowers operating noise and improves the working environment. The smooth engagement also minimizes impact and wear, extending the lifespan of the gears and racks.

Selectable Zones

The worktable of the CNC cutting machine is designed with multiple independent vacuum suction zones. Each zone is connected to the vacuum pump system via a separate valve. The operator or system software can selectively activate or deactivate these zones based on the size and position of the material to be cut. Only the selected zones will generate vacuum pressure, securely holding the material in place.

This is particularly important when cutting smaller materials. Activating the entire worktable would disperse the suction force, reducing efficiency. The selectable zone feature concentrates the vacuum suction directly beneath the material, providing stronger localized suction. This ensures the material remains completely stationary during high-speed cutting, preventing misalignment or warping, and thus avoiding potential errors – which is especially crucial for lightweight or easily deformable materials.

Large-format CCD digital cutting machines, combined with a projector system, can accurately and perfectly cut custom leather pieces, inlaid carpets, curtain patterns, insole stickers, printed fabrics, patchwork, pattern-making fabrics, printed graphics, automotive decals, self-adhesive vinyl, door stickers, and more.

This large-format CCD digital cutting machine is equipped with a wide-angle CCD vision system that quickly identifies complete pattern outlines and defect areas. Combined with a projector, the system accurately projects the cutting path onto the material surface, allowing operators to intuitively align and efficiently nest designs. The system supports advanced functions such as automatic contour recognition, defect avoidance, and intelligent nesting of irregular patterns, significantly improving cutting accuracy and efficiency. It is widely used in the following industries: advertising, apparel, automotive interiors, carpets, carbon fiber/composite materials, leather goods and footwear manufacturing, packaging, and home decor.
