Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a laser cutting device for metal casings used in the processing of mobile power supplies. Background Technology

[0002] With the widespread use of portable electronic devices, the demand for power banks as emergency power supply equipment continues to rise, and consumers are increasingly demanding higher standards for the appearance, structural strength, and lightweight design of power banks. Metal materials (such as aluminum alloys and stainless steel), due to their excellent thermal conductivity, impact resistance, and metallic luster, are gradually replacing traditional plastic materials and becoming the mainstream choice for mid-to-high-end power bank casings. The processing of power bank metal casings involves multiple steps, including profile forming, cutting, grinding, and surface treatment, with laser cutting being a key process.

[0003] During the laser cutting and subsequent grinding processes of the metal casing of power banks, high-temperature molten metal slag and fine debris are generated. These cutting residues are prone to splashing and adhering to the internal cavities, cut surfaces, and complex gaps of the workpiece. Not only are they difficult to clean thoroughly, but they also directly affect the quality of subsequent surface treatment processes such as spraying and anodizing, leading to reduced coating adhesion, appearance defects, and ultimately affecting product yield and overall quality.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Example: Please see Figures 1-8 The present invention provides a technical solution: a metal shell laser cutting device for processing mobile power supplies, including a frame 1, a mounting plate 2 fixedly connected to the top outer wall of the frame 1, a laser cutting head 3 provided on the mounting plate 2, and a dust suction structure 4 installed on the outer wall of the mounting plate 2; A waste discharge port 5 is provided on the frame 1 and below the laser cutting head 3, and a cutting waste collection box 501 is provided below the waste discharge port 5; The frame 1 is also equipped with a rotary clamping mechanism 6 located on one side of the laser cutting head 3. The rotary clamping mechanism 6 clamps and fixes the metal shell. The rotary clamping mechanism 6 is equipped with a dust suction structure 7. A sealing and dustproof structure 8 is provided on one side of the rotary clamping mechanism 6.

[0020] In this embodiment, the metal shell is clamped by the rotating clamping mechanism 6, and the rotating clamping mechanism 6 drives the metal shell to move laterally. The sealing and dustproof structure 8 seals the inside of the metal shell to prevent metal slag from entering. The dust suction structure adsorbs dust and metal particles during cutting and grinding.

[0021] The dust collection structure 4 includes a bidirectional lead screw 401, which is mounted on two mounting plates 2. A guide rod 402 is fixedly connected between the outer walls of the mounting plates 2. A motor 403 is fixedly connected to one outer wall of the mounting plate 2. The output shaft of the motor 403 is connected to one end of the bidirectional lead screw 401. A moving block 404 is slidably connected to the outer wall of the guide rod 402. Two moving blocks 404 are provided on each guide rod 402. The inner walls of the two moving blocks 404 are connected to the bidirectional lead screw 401. The outer wall of 01 is threaded, and the threads on the bidirectional lead screw 401 of the two moving blocks 404 are in opposite directions. An industrial vacuum cleaner 405 is provided on the outer wall of the mounting plate 2. A suction pipe 406 is provided at the output end of the industrial vacuum cleaner 405. A branch connecting pipe 407 is fixedly connected to the bottom outer wall of the moving block 404. One end of the suction pipe 406 is connected to the branch connecting pipe 407. An upper suction nozzle 409 and a lower suction nozzle 408 are respectively provided on the upper and lower sides of the branch connecting pipe 407.

[0022] The upper suction nozzle 409 and the lower suction nozzle 408 both adopt a trumpet-shaped structure, and the branch connecting pipe 407 adopts a flexible corrugated pipe.

[0023] In this embodiment, the motor 403 is started, which drives the bidirectional lead screw 401 to rotate. Since the threads of the two moving blocks 404 and the bidirectional lead screw 401 are opposite, and the moving blocks 404 are slidably connected to the guide rod 402, the rotation of the bidirectional lead screw 401 drives the two moving blocks 404 to move relative to or towards each other along the guide rod 402. The positions of the upper suction nozzle 409 and the lower suction nozzle 408 on the upper and lower sides of the branch connecting pipe 407 are adjusted so that the upper suction nozzle 409 is aligned with the cutting position of the laser cutting head 3. The industrial vacuum cleaner 405 uses the upper suction nozzle 409 to suck up the floating cutting slag and dust generated during the cutting process through the suction pipe 406 and the branch connecting pipe 407, and uses the lower suction nozzle 408 to suck up the larger particles of cutting slag that fall off.

[0024] The rotary clamping mechanism 6 includes a mounting frame 601, a transverse lead screw 602 rotatably connected to the inner wall of the frame 1, a motor 603 fixedly connected to one side of the outer wall of the frame 1, the output shaft of the motor 603 being connected to one end of the transverse lead screw 602, a slide rod 604 fixedly connected to the outer wall of the frame 1, the mounting frame 601 being threadedly connected to the transverse lead screw 602, and the mounting frame 601 being slidably connected to the slide rod 604. A mounting plate 605 is fixedly connected to the outer wall of the mounting frame 601, a large gear 606 rotatably connected to the inner wall of the mounting plate 605, a drive gear 607 rotatably connected to the outer walls of the mounting frame 601, the drive gear 607 meshing with the outer wall of the large gear 606, a motor 608 connected to the drive gear 607 being provided on the outer wall of the mounting frame 601, and a metal housing placement groove being provided at the center of the large gear 606, with a workpiece clamping assembly 609 placed in the placement groove.

[0025] The workpiece clamping assembly 609 includes a clamping cylinder and an arc-shaped clamping block. The clamping cylinder is fixed to the inner wall of the metal housing placement groove, and the arc-shaped clamping block is fixed to the end of the piston rod of the clamping cylinder. The inner wall of the arc-shaped clamping block is provided with an anti-slip rubber pad.

[0026] In this embodiment, the metal casing of the power bank to be processed is placed in the metal casing placement slot of the rotary clamping mechanism 6, and the workpiece clamping assembly 609 is activated to firmly clamp the metal casing.

[0027] Start motor 2 603, which drives the transverse lead screw 1 602 to rotate. Mounting bracket 1 601 is threadedly connected to the transverse lead screw 1 602 and slidably connected to the slide rod 1 604. As the transverse lead screw 1 602 rotates, it moves laterally along the slide rod 1 604 to adjust the transverse position of the metal shell so that it is precisely aligned with the cutting position of the laser cutting head 3.

[0028] The second dust collection structure 7 includes an industrial vacuum cleaner 701, a suction pipe 702, and an auxiliary suction nozzle 703. The industrial vacuum cleaner 701 is fixed on the mounting bracket 601. One end of the suction pipe 702 is connected to the industrial vacuum cleaner 701, and the other end is connected to the auxiliary suction nozzle 703. The auxiliary suction nozzle 703 is set towards the clamping position of the workpiece clamping assembly 609.

[0029] The grinding structure 9 includes an eccentric grinding wheel 901, a movable groove 902, and a grinding drive motor 903. The movable groove 902 is opened on the frame 1, and the grinding drive motor 903 is assembled in the movable groove 902. The eccentric grinding wheel 901 is connected to the output end of the grinding drive motor 903.

[0030] In this embodiment, the industrial vacuum cleaner 701 of the vacuuming structure 7 is activated, and the grinding residue around the clamping part of the workpiece clamping assembly 609 is adsorbed through the vacuum pipe 702 and the auxiliary vacuum nozzle 703.

[0031] The sealing and dustproof structure 8 includes a mounting bracket 801, a transverse lead screw 805 rotatably connected to the inner wall of the frame 1, a motor 806 fixedly connected to one side of the outer wall of the frame 1, the output shaft of the motor 806 being connected to one end of the transverse lead screw 805, a slide rod 807 fixedly connected to the outer wall of the frame 1, the mounting bracket 801 being threadedly connected to the transverse lead screw 805, and the mounting bracket 801 being slidably connected to the slide rod 807. A mounting plate 802 is fixedly connected to the outer wall of the mounting bracket 801, and a rotating wheel 803 rotatably connected to the inner wall of the mounting plate 802. A sealing post 804 is provided inside the rotating wheel 803, and the sealing post 804 is inserted into the metal shell to seal the metal shell.

[0032] In this implementation scheme, the four motors 806 are started, which drives the two transverse lead screws 805 to rotate. The rotation of the two transverse lead screws 805 drives the two mounting brackets 801 to move laterally along the two sliding rods 807 until the sealing column 804 penetrates into the metal shell and seals the metal shell to prevent cutting debris from splashing into the internal cavity of the shell during the cutting and grinding process.

[0033] Working principle: The metal shell of the mobile power bank to be processed is placed in the metal shell placement slot of the rotary clamping mechanism 6. The workpiece clamping assembly 609 is activated, and the workpiece clamping assembly 609 firmly clamps the metal shell. After clamping is completed, the sealing and dustproof structure 8 and the adjustment mechanism of the rotary clamping mechanism 6 are activated to complete the sealing of the metal shell and the alignment of the work position. Start motor 4 806, which drives transverse lead screw 2 805 to rotate. The rotation of transverse lead screw 2 805 drives mounting bracket 2 801 to move laterally along slide rod 2 807 until sealing column 804 penetrates into the metal shell to seal the metal shell and prevent cutting debris from splashing into the internal cavity of the shell during cutting and grinding. Start motor 2 603, which drives the transverse lead screw 1 602 to rotate. Mounting bracket 1 601 is threadedly connected to the transverse lead screw 1 602 and slidably connected to the slide rod 1 604. As the transverse lead screw 1 602 rotates, it moves laterally along the slide rod 1 604 to adjust the transverse position of the metal shell so that it is precisely aligned with the cutting position of the laser cutting head 3.

[0034] After the workstation is aligned, the laser cutting head 3 and the dust collection structure 4 are started to begin the laser cutting operation on the metal shell. The motor 608 is started, which drives the drive gear 607 to rotate. The drive gear 607 meshes with the large gear 606, which drives the large gear 606 to rotate around the mounting plate 605, thereby driving the metal shell in the slot to rotate synchronously, thus achieving all-round cutting of the metal shell.

[0035] Start motor 403, which drives the bidirectional lead screw 401 to rotate. Since the threads of the two moving blocks 404 and the bidirectional lead screw 401 are opposite, and the moving blocks 404 are slidably connected to the guide rod 402, the rotation of the bidirectional lead screw 401 drives the two moving blocks 404 to move relative to or towards each other along the guide rod 402. Adjust the positions of the upper suction nozzle 409 and the lower suction nozzle 408 on both sides of the branch connecting pipe 407 so that the upper suction nozzle 409 is aligned with the cutting position of the laser cutting head 3. The industrial vacuum cleaner 405 uses the upper suction nozzle 409 to suck up the floating cutting slag and dust generated during the cutting process through the suction pipe 406 and the branch connecting pipe 407, and uses the lower suction nozzle 408 to suck up the larger particles of cutting slag that fall off.

[0036] After laser cutting is completed, the laser cutting head 3 is closed, and the rotating clamping mechanism 6 and the sealing dustproof structure 8 move away from the laser cutting head 3, moving to the side of the grinding structure 9. The grinding structure 9 is then activated to grind and trim the cut edges of the metal shell. The grinding drive motor 903 is mounted in the movable slot 902 of the frame 1. The grinding drive motor 903 is activated, driving the eccentric grinding wheel 901 to rotate. The eccentric grinding wheel 901 grinds the burrs on the metal shell. The industrial vacuum cleaner 701 of the dust collection structure 7 is activated, and the grinding debris around the clamping part of the workpiece clamping assembly 609 is adsorbed through the suction pipe 702 and the auxiliary suction nozzle 703.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
