Description

Technical Field

[0001] This invention relates to an automatic laser cutting and storage machine for amorphous ribbon. Background Technology

[0002] Amorphous alloys are a high-tech material, also known as a new type of material with novel functions for the next century. They are key materials in high-tech fields such as power, electronics, computers, and communications, possessing excellent physical, chemical, and mechanical properties. Their market demand will be very large, and their industrialization prospects are very broad.

[0003] Amorphous soft magnetic alloys possess excellent soft magnetic properties due to their microstructure characterized by short-range order and long-range disorder. Amorphous soft magnetic alloy strips are currently the most widely produced and applied amorphous alloy material globally, extensively used in transformers, instrument transformers, and motors. They have experienced rapid development and widespread application in recent years. They have been successfully applied to the cores of power and electronic transformers, reducing no-load losses by more than 70%. Internationally, many countries have invested heavily in developing this amorphous alloy industry. The increasingly widespread application and growing demand for amorphous strips have created new requirements for their processing methods. Because the soft magnetic properties of amorphous strips are easily affected by mechanical stress, current cross-cutting machines based on mechanical shearing principles tend to degrade these properties. Summary of the Invention

[0004] To overcome the problems existing in the prior art, the present invention proposes an automatic laser shearing and storage machine for amorphous ribbon. By utilizing the high energy density of laser, the cut seam of the ribbon is vaporized in a short time, which can greatly reduce the heat-affected zone of the ribbon. Furthermore, when shearing multilayer amorphous materials, the heat-affected zones of the upper and lower layers of amorphous ribbon are almost the same, which greatly reduces the heat-affected zone and thus reduces the deterioration of soft magnetic properties caused by shearing amorphous materials.

[0005] The technical solution of this invention to solve the above problems is: an automatic laser shearing and storage machine for amorphous ribbon, which is special in that:

[0006] Includes a web alignment machine, a laser cutting mechanism, and a strip storage box.

[0007] The alignment machine is used to transport amorphous ribbon and align the amorphous ribbon. The laser cutting mechanism cuts the amorphous ribbon transported by the alignment machine. The ribbon storage box is used to store the cut amorphous ribbon.

[0008] The laser cutting mechanism includes a laser emitter and a first housing. A first window is provided on the top of the first housing. Several transmission plates and rubber rollers are provided inside the first housing. A rubber roller is provided between two adjacent transmission plates. A clamping device is provided above the rubber roller. The rubber roller and the clamping device cooperate to drive the amorphous ribbon to move on the transmission plates. The laser emitted by the laser emitter enters the housing through the first window and cuts the amorphous ribbon.

[0009] The strip storage box includes a second box body, and an L-shaped strip collection rack is provided inside the second box body. The cut amorphous strip falls into the L-shaped strip collection rack.

[0010] Furthermore, the second housing is also equipped with a moving mechanism, which includes a motor and a first lead screw and nut assembly. The bottom of the L-shaped strip collecting frame is fixed to the nut of the first lead screw and nut assembly by a mounting base. The motor drives the lead screw to move the nut up and down, and the L-shaped strip collecting frame moves accordingly. As the amount of collected strip increases, the motor drives the L-shaped strip collecting frame to slowly descend and catch the slipping processed strip.

[0011] Furthermore, the aforementioned alignment machine includes at least two tiltable rollers and a laser detector. The laser detector detects the side position of the strip and adjusts the tiltable rollers according to the detection results to ensure that the relative position of the amorphous strip on the tiltable rollers remains constant.

[0012] Furthermore, the aforementioned laser cutting mechanism also includes a second lead screw and nut assembly, which is disposed on one side of the first housing. The laser emitter is fixed on the nut of the second lead screw and nut assembly, and a handwheel is connected to the upper end of the lead screw of the second lead screw and nut assembly, which drives the lead screw to rotate.

[0013] Furthermore, the aforementioned L-shaped strip collecting rack is inclinedly mounted on the mounting base to smoothly receive the cut amorphous strip, preventing the latter end from colliding with other strips and affecting their performance.

[0014] Furthermore, a window is provided on the side of the second housing for retrieving the strip from the L-shaped strip collection rack.

[0015] Furthermore, the first housing is equipped with two clamping devices. The clamping device closer to the second housing generates a greater pressure than the other clamping device, thereby ensuring that the strip remains in close contact with the surface of the transmission plate.

[0016] Furthermore, the aforementioned clamping device includes an L-shaped fixing plate, a spring, a torsion spring, and a pressure plate. The L-shaped fixing plate is fixed to the upper bottom surface of the first housing. The upper surface of the pressure plate is connected to the lower bottom surface of the L-shaped fixing plate via a spring. The tail end of the pressure plate is connected to the first housing via a torsion spring. A ball bearing is provided on the lower side of the head of the pressure plate, and the ball bearing corresponds to a rubber roller.

[0017] Furthermore, the first window mentioned above is a long and narrow window.

[0018] Furthermore, the aforementioned second housing is provided with heat dissipation holes.

[0019] Advantages of this invention:

[0020] This invention utilizes the high energy density of lasers to vaporize the kerf of the strip in a short time, significantly reducing the heat-affected zone (HAZ) and thus minimizing the deterioration of soft magnetic properties caused by shearing amorphous materials. Simultaneously, this invention enables automatic strip collection, eliminating the need for excessive worker intervention, increasing work efficiency, and saving human resources. The cutting speed is faster than mechanical shearing devices, significantly improving production efficiency. Attached Figure Description

The laser emitted by the laser emitter 4 enters the first housing 5 through the first window 6, cutting the amorphous ribbon. The first window 6 is a long, narrow window.

[0030] In some embodiments of the present invention, the first housing 5 is provided with two clamping devices, and the pressure generated by the clamping device closer to the second housing 9 is greater than the pressure of the other clamping device.
