Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and in particular to a soft material cutting and processing equipment and a use method thereof. Background Art

[0002] Soft material cutting and processing equipment is a mechanical or automated system specially designed for accurately and efficiently cutting various flexible or semi-rigid materials. These materials are usually easy to deform, stretch, wear or delaminate, so specific cutting technology and equipment are required to ensure cutting quality and efficiency.

[0003] There are many types of soft material cutting and processing equipment. The choice of equipment depends on factors such as the specific material type, thickness, required cutting accuracy, edge quality requirements, production efficiency (single layer / multi-layer), budget, and whether there are special requirements (such as edge melting and no heat impact). Vibrating knife, laser and ultrasonic cutting are currently the most widely used and technologically mature CNC soft material cutting solutions.

[0004] Existing soft material cutting and processing equipment has the following shortcomings during actual use: 1. The single cutting method is very limited. The vibrating knife is prone to delamination of multi-layer high-elastic materials, the laser is prone to carbonization when cutting heat-sensitive materials, and the ultrasonic cutting efficiency of thick materials is low; 2. The tool change downtime is long, and multiple process requirements require frequent equipment replacement, which reduces the continuity of the production line. For this reason, a soft material cutting and processing equipment and its use method are proposed, which integrates three cutting modes: vibrating knife, laser, and ultrasonic, and is suitable for the automated processing of high-precision and multi-variety soft materials such as composite materials, ultra-thin fibers, and heat-sensitive foams. Summary of the Invention

[0005] The present invention provides a soft material cutting and processing equipment and a method for using the same, which solves the problems of large limitations of traditional single cutting and processing equipment, such as easy delamination of multi-layer high-elastic materials by vibrating knives, easy carbonization of heat-sensitive materials by laser cutting, low efficiency of ultrasonic cutting of thick materials, and frequent equipment replacement required for multiple processes, which reduces the continuity of the production line. The equipment integrates three cutting modes: vibrating knife, laser and ultrasonic cutting, and is suitable for the automated processing of high-precision and multi-variety soft materials.

[0006] The present invention solves the above technical problems as follows: A soft material cutting and processing equipment includes an equipment bracket, a vacuum adsorption platform, a servo three-axis mobile platform, a winder, an unwinder, an axial tool changer platform, a multi-modal cutting unit, and an equipment host. The vacuum adsorption platform, the servo three-axis mobile platform, and the equipment host are all arranged on the top of the equipment bracket, and the winder and unwinder are respectively placed on both sides of the equipment bracket. The Z-axis driving end of the servo three-axis mobile platform drives the axial tool changer platform to rise and fall, and the axial tool changer platform drives the multi-modal cutting unit to rotate and change tools. The multi-modal cutting unit is provided with a vibrating knife, a fiber laser cutting knife, and an ultrasonic cutting knife. The equipment host is provided with a material database and a process decision engine.

[0007] The usage includes the following steps:

[0008] S1, material database construction, builds the material database based on material supplier data, standard test reports, laboratory measured data and historical production data;

[0009] S2: Material property matching. The winder and unwinder transfer the fabric to the equipment bracket. The vacuum adsorption platform can vacuum adsorb and fix the material. The material parameters are input from the equipment host. The process decision engine queries the material properties to determine whether there is a risk of delamination. If so, ultrasonic contour edge banding is performed. If there is no delamination risk, the main body cutting is carried out directly.

[0010] S3, select the appropriate cutting mode according to the thermal sensitivity level of the material. Ultrasonic cutting knives are used for protecting loose surfaces or heat sealing. Fiber laser cutting knives are used for high-precision areas with fine patterns or chemical fiber fabrics. Vibrating knives are used for hard multi-layered fabrics or areas with a curvature radius greater than 5mm.

[0011] S4, cutting processing, the servo three-axis mobile platform can drive the axial tool changing platform and the multi-modal cutting unit at its bottom to move on the top of the vacuum adsorption platform, thereby driving the tool to cut the fabric on the top;

[0012] S5, quality self-inspection, after processing, the cut material can be taken out, the cutting contour can be compared with the design drawing, and the part that exceeds the tolerance can be marked for repair.

[0013] On the basis of the above technical solution, the present invention can also be improved as follows.

[0014] Furthermore, the axial tool changing platform is rotatably connected to an annular bearing seat and is rotatably connected to the multimodal cutting unit through the annular bearing seat. The axial tool changing platform is provided with a stepping motor. The axial tool changing platform is rotatably connected to a support rod. The driving end of the stepping motor and the support rod are both fixedly installed with bevel gears. The driving end of the stepping motor and the support rod are connected through a bevel gear transmission. The driving end of the support rod is fixedly connected to the multimodal cutting unit.

[0015] Furthermore, the multimodal cutting unit is fixedly mounted with a partition plate, and the multimodal cutting unit is separated into an equipment chamber and a hydraulic cylinder chamber by the partition plate.

[0016] Furthermore, the multimodal cutting unit is fixedly installed with a tool telescopic hydraulic cylinder, and three tool telescopic hydraulic cylinders are provided. The driving ends of the three tool telescopic hydraulic cylinders are respectively connected to the vibrating knife, the fiber laser cutting knife, and the ultrasonic cutting knife by bolts.

[0017] Furthermore, the drivers of the vibrating knife, the fiber laser cutting knife, and the ultrasonic cutting knife are all installed in the equipment cavity, and the tool telescopic hydraulic cylinders are evenly arranged and installed in the hydraulic cylinder cavity.

[0018] Furthermore, the equipment bracket is provided with a cooling air inlet cover.

[0019] Furthermore, in step S1, the material data includes thickness, elastic modulus, thermal sensitivity level, delamination risk, critical speed of edge fray, maximum allowable temperature, and compression coefficient.

[0020] Furthermore, in step S4, starting the stepper motor can drive the multimodal cutting unit to rotate at the bottom of the annular bearing seat, so that the vibrating knife, fiber laser cutting knife, and ultrasonic cutting knife can be adjusted to the cutting point. After the tool is rotated and adjusted to the cutting point, the tool telescopic hydraulic cylinder can be started to descend, so that the cutting tool protrudes, so that the fabric can be cut under the Z-axis adjustment of the servo three-axis mobile platform.

[0021] The beneficial effects of the present invention are as follows: the present invention provides a soft material cutting and processing device and a method of using the same, which have the following advantages:

[0022] 1. It solves the problems of traditional single cutting equipment with large limitations, such as the easy delamination of multi-layer high-elastic materials by vibration knives, the easy carbonization of heat-sensitive materials by laser cutting, and the low efficiency of ultrasonic cutting of thick materials.

It is equipped with a multi-cutting mode adjustment structure to quickly adjust to different cutting process requirements, thereby improving processing efficiency.

[0024] 3. It solves the problems of single-mode limitation and low tool change efficiency of traditional cutting equipment, and is particularly suitable for high-precision soft material processing such as automotive interiors and medical materials.
