Abstract

This utility model relates to a magnetic sheet metal laser cutting device for easy unloading, which includes a frame, a transmission mechanism, a laser cutting mechanism, and a material handling mechanism. The material handling mechanism includes a fixed frame, a moving plate, a Y-axis moving component, a Z-axis moving component, and an electromagnetic component. The electromagnetic component includes a connecting frame, a connecting shaft, a material handling block, a conductive wire, an electromagnetic coil, and an iron core. After laser cutting is completed, the material handling mechanism moves in the same direction as the laser cutting machine via the moving frame. When the electromagnetic component is energized, the iron core generates a strong magnetic field, which attracts the cut magnetic sheet metal parts through the protrusions. This avoids the need to unload the magnetic sheet metal parts as a whole and then manually remove them one by one. Compared with a robotic arm, it also eliminates the need to preset a precise gripping path. The Z-axis moving component can control the distance between the material handling block and the cutting table to ensure that the adsorption force is adapted to workpieces of different thicknesses. After the material handling is completed, the Y-axis moving mechanism can move the material handling block to one side of the frame, and the electromagnetic component demagnetizes to achieve rapid unloading.

Description

Technical Field

[0001] This utility model relates to the field of magnetic sheet metal processing, and in particular to a magnetic sheet metal laser cutting device that facilitates material cutting. Background Technology

[0002] In the manufacturing industry, magnetic sheet metal (such as cold-rolled steel sheet, hot-rolled steel sheet, SUS430 stainless steel, etc.) is widely used in the production of automotive parts, home appliance structural parts, mechanical parts and other fields due to its excellent mechanical properties and magnetic characteristics. Laser cutting, as the core process for cutting magnetic sheet metal, has become the mainstream processing method in the industry due to its advantages such as high cutting precision and smooth cut.

[0003] After the current mainstream laser cutting equipment completes the magnetic sheet metal cutting, the cut sheet metal parts, such as small gaskets and irregularly shaped structural parts, are still scattered on the cutting table and need to be picked up manually by the operator one by one. In order to improve the problem of manual material picking, some companies have tried to use auxiliary methods such as robotic arm gripping and vacuum suction cup adsorption, but all of them have obvious defects. Robotic arm gripping requires a precise gripping path to be preset. For sheet metal parts with complex shapes and various sizes, the program parameters need to be adjusted frequently, resulting in poor adaptability. In addition, the end clamp of the robotic arm is prone to interference with the cutting table or the uncut sheet metal. Vacuum suction cup adsorption relies on a sealed contact surface. If there is oil, cutting residue or slight unevenness on the magnetic sheet metal surface, it will cause the suction cup to lose its sealing performance and cause the adsorption to fall off. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a magnetic sheet metal laser cutting device that facilitates material cutting.

[0005] The magnetic sheet metal laser cutting device for easy material cutting provided by this utility model adopts the following technical solution:

[0006] A magnetic sheet metal laser cutting device for easy material unloading includes a frame, a transmission mechanism, a laser cutting mechanism, and a material handling mechanism. The transmission mechanism is mounted on the frame. The laser cutting mechanism includes a movable frame and a laser cutter. The material handling mechanism is fixed on the movable frame and includes a fixed frame, a movable plate, a Y-axis moving assembly, a Z-axis moving assembly, and an electromagnetic assembly. The fixed frame is fixed to the side wall of the movable frame. The Y-axis moving assembly is mounted on the fixed frame and drives the movable plate to move along the Y-axis. The Z-axis moving assembly is fixed on the movable plate and drives the electromagnetic assembly to move vertically.

[0007] Optionally, the electromagnetic assembly includes a connecting frame, a connecting shaft, a material picking block, a conductive wire, an electromagnetic coil, and an iron core. The Z-axis moving assembly drives the connecting frame to move up and down. The connecting shaft is disposed between the connecting frames. The material picking block is fixed on the connecting shaft. The iron core is fixed on the material picking block. The electromagnetic coil is coiled on the iron core. The protrusion of the iron core extends from the surface of the material picking block. The connecting shaft is hollow. The conductive wire enters the interior of the material picking block through the connecting shaft and forms an electrical connection with the electromagnetic coil.

[0008] Optionally, the electromagnetic assembly further includes a motor, a driving wheel, a driven wheel, and a belt. The motor is mounted on the connecting frame, and its output end is connected to the driving wheel. The belt is tensioned on the driving wheel and the driven wheel. The driven wheel is fixed to one end of the connecting shaft, which is rotatably connected to the connecting frame. The material picking block is hexagonal, with several iron cores spaced apart on each of its six surfaces. The other end of the connecting shaft is connected to a rotor, and the conductive wire achieves a stable electrical connection with the conductive wire passing through the connecting shaft via the rotor's slip ring.

[0009] Optionally, a limiting mechanism is also included, which includes a connector, a connecting column, and a roller. The connector is symmetrically arranged on the inner wall of the frame, the connecting column is fixed to the bottom of the connector, and the roller is rotatably connected to the bottom of the connecting column. The roller is used to prevent the sheet metal part from moving vertically.

[0010] Optionally, the limiting mechanism further includes a spring, the connecting column is a telescopic column, a limiting piece is provided at the bottom of the telescopic column, one end of the spring abuts against the limiting piece, and the other end abuts against the bottom wall of the connecting piece.

[0011] Optionally, the transmission mechanism includes a drive, a chain, a sprocket, and several toothed plates. The drive drives the sprocket to rotate, the sprocket drives the chain to move, and the two ends of the several toothed plates are connected to the chain.

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] 1. After laser cutting is completed, the material handling mechanism moves in the same direction as the laser cutting machine via a moving frame. When the electromagnetic component is energized, the iron core generates a strong magnetic field, which attracts the cut magnetic sheet metal parts through the protrusions. This avoids manually removing the magnetic sheet metal parts one by one after unloading the entire piece, greatly improving material handling efficiency. Compared with a robotic arm, there is no need to preset a precise gripping path. The Z-axis moving component can precisely control the distance between the material handling block and the cutting table, ensuring that the adsorption force is adapted to workpieces of different thicknesses. When the material handling is completed, the Y-axis moving mechanism can move the material handling block to one side of the frame and achieve rapid unloading by demagnetizing it through the electromagnetic component.

[0014] 2. The six-sided picking block, with its six-surface iron core layout, can pick up magnetic sheet metal parts of different shapes and sizes. The motor drives the connecting shaft to rotate, and the drive wheel, belt, and driven wheel drive the quick switching of the adsorption surface. It can pick up a variety of workpieces without changing the picking tool. The rotor slip ring design at the end of the connecting shaft solves the problem of conductive wire entanglement when the picking block rotates. The conductive wire is dynamically electrically connected to the internal wire of the connecting shaft through the slip ring. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Furthermore, "several" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0022] This utility model discloses a magnetic sheet metal laser cutting device that facilitates material cutting. (See reference...) Figure 1-3 A magnetic sheet metal laser cutting device for easy material unloading includes a frame 1, a transmission mechanism 2, a laser cutting mechanism 3, and a material handling mechanism 4. The transmission mechanism 2 is mounted on the frame 1 and includes a drive, a chain 22, a sprocket, and several toothed plates 21. The drive drives the sprocket to rotate, and the sprocket drives the chain 22 to move. The two ends of the several toothed plates 21 are connected to the chain 22. The transmission mechanism 2 transports the magnetic sheet metal to the cutting position, and the laser cutting mechanism 3 completes the cutting operation under the drive of the moving frame 31.

[0023] The laser cutting mechanism 3 includes a movable frame 31 and a laser cutting machine 32. A material handling mechanism 4 is fixed to the movable frame 31. The material handling mechanism 4 includes a fixed frame 41, a movable plate 42, a Y-axis moving assembly 43, a Z-axis moving assembly 44, and an electromagnetic assembly 45. The fixed frame 41 is fixed to the side wall of the movable frame 31. The Y-axis moving assembly 43 is mounted on the fixed frame 41 and drives the movable plate 42 to move along the Y-axis. The Z-axis moving assembly 44 is fixed to the movable plate 42 and drives the electromagnetic assembly 45 to move vertically. The electromagnetic assembly 45 includes a connecting frame 450, a connecting shaft 451, a material handling block 452, a conductive wire 453, an electromagnetic coil, and an iron core 454. The Z-axis moving assembly 44 drives the connecting frame 450 to move up and down. The connecting shaft 451 is positioned between the connecting frames 450. The material handling block 452 is fixed to the connecting shaft 451, and the iron core 454 is fixed to the material handling block 452. The electromagnetic coil is coiled around the iron core 454. On the core 454, the protrusion of the iron core 454 extends from the surface of the picking block 452. The connecting shaft 451 is hollow. The conductive wire 453 enters the interior of the picking block 452 through the connecting shaft 451 and forms an electrical connection with the electromagnetic coil. With this design, after laser cutting is completed, the picking mechanism 4 moves in the same direction as the laser cutting machine 32 (i.e., X-axis movement) through the moving frame 31. After the electromagnetic component 45 is energized, the iron core 454 generates a strong magnetic field, which attracts the cut magnetic sheet metal parts through the protrusion. This avoids the need to unload the magnetic sheet metal parts as a whole and then manually pick them up one by one, greatly improving the picking efficiency. Compared with the robotic arm, there is no need to preset a precise gripping path. The Z-axis moving component 44 can accurately control the distance between the picking block 452 and the cutting table to ensure that the adsorption force is adapted to workpieces of different thicknesses. When the picking is completed, the Y-axis moving mechanism can move the picking block 452 to one side of the frame 1 and achieve rapid unloading by demagnetizing through the electromagnetic component 45.

[0024] The electromagnetic assembly 45 also includes a motor 455, a driving wheel 456, a driven wheel 457, and a belt 458. The motor 455 is mounted on the connecting frame 450. The output end of the motor 455 is connected to the driving wheel 456. The belt 458 is tensioned on the driving wheel 456 and the driven wheel 457. The driven wheel 457 is fixed to one end of the connecting shaft 451. The connecting shaft 451 is rotatably connected to the connecting frame 450. The material taking block 452 is hexagonal, and several iron cores 454 are spaced apart on each of the six surfaces of the material taking block 452. The other end of the connecting shaft 451 is connected to a rotor 459. The conductive wire 453 passes through the slip ring of the rotor 459 and runs through the connecting shaft. The conductive wire 453 inside 451 achieves a stable electrical connection. With this design, the six-sided picking block 452, together with the six-surface iron core 454, can pick up magnetic sheet metal parts of different shapes and sizes. The motor 455 drives the connecting shaft 451 to rotate, and through the drive wheel 456, belt 458, and driven wheel 457, the adsorption surface can be quickly switched. The picking tool can be changed to pick up a variety of workpieces. The rotor 459 at the end of the connecting shaft 451 has a slip ring design, which solves the problem of the conductive wire 453 winding when the picking block 452 rotates. The conductive wire 453 achieves a dynamic electrical connection with the internal wire of the connecting shaft 451 through the slip ring.

[0025] The frame 1 is also equipped with a limiting mechanism 5, which includes a connector 51, a connecting column 52 and a roller 53. The connector 51 is symmetrically arranged on the inner wall of the frame 1. The connecting column 52 is fixed to the bottom of the connector 51. The roller 53 is rotatably connected to the bottom of the connecting column 52. The roller 53 is used to prevent the sheet metal parts from moving vertically. The limiting mechanism 5 is designed to prevent the sheet metal parts from jumping when the electromagnetic component 45 is working. The roller 53 is designed to prevent scratches and indentations from appearing on the surface of the sheet metal parts.

[0026] The limiting mechanism 5 also includes a spring 54. The connecting column 52 is a telescopic column with a limiting plate at the bottom. One end of the spring 54 abuts against the limiting plate, and the other end abuts against the bottom wall of the connecting piece 51. The combination of the telescopic column and the spring 54 forms an elastic adaptive structure. When there are differences in the thickness of the sheet metal parts or slight undulations on the surface, the spring 54 will automatically adjust the extension length of the telescopic column through its own elasticity, so that the roller 53 always adheres to the surface of the sheet metal parts with stable pressure.

[0027] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
