Description

Technical Field

[0001] This utility model relates to the field of laser marking machine technology, specifically a rotatable laser marking machine. Background Technology

[0002] Laser marking machines, also known as laser coding machines or laser engraving machines, are devices that use laser beams to create permanent marks on the surfaces of various materials. The marking effect is achieved by evaporating the surface material to expose the deeper material, causing chemical or physical changes in the surface material to "etch" a mark, or by burning away part of the material with light energy to reveal the desired pattern or text.

[0003] A laser marking machine is currently available, as described in Chinese Patent Application No. CN202010834881.2. The laser marking machine includes a frame, a horizontal displacement mechanism, a marking mechanism, a loading mechanism, a lifting mechanism, and a suction mechanism. The frame includes a worktable; the horizontal displacement mechanism is mounted on the worktable; the marking mechanism is used to mark the workpiece; the loading mechanism is mounted on the horizontal displacement mechanism and is used to place the workpiece, and can move horizontally on the horizontal displacement mechanism; the lifting mechanism is mounted on the worktable; the suction mechanism is mounted on the lifting mechanism and located above the loading mechanism, and is used to suction the workpiece, and can be adjusted upwards or downwards on the lifting mechanism. This laser marking machine, by using an automated mechanical suction device, can automatically load and unload workpieces, thereby improving the automation level of the laser marking machine and thus increasing its loading and unloading efficiency.

[0004] The device lacks a rotating mechanism, which means that the products being processed can only be marked on flat or simple linear surfaces, and cannot be marked on circular, curved, or other complex shapes. This will greatly limit the application range of the laser marking machine.

[0005] Therefore, we propose a rotatable laser marking machine to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a rotatable laser marking machine to solve the problem mentioned in the background art: the existing devices lack a rotating mechanism. The lack of a rotating mechanism means that the processed products can only be marked on a flat or simple linear surface, and cannot be marked on circular, curved, or other complex shaped surfaces. This greatly limits the application range of laser marking machines.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rotatable laser marking machine, comprising a base, a motor installed inside the base, and a small gear connected to the output end of the motor via a fixed shaft. A large gear is meshed with the right side of the small gear, a connecting plate is connected to the top of the large gear via a rotating shaft, and a support frame is fixedly connected to the top of the connecting plate. A threaded rod is rotatably connected inside the support frame, and a threaded block is threadedly connected to the outside of the threaded rod. A support arm is fixedly connected to one side of the threaded block, a laser is disposed on the right side of the support arm, and a drive motor is installed inside the support frame.

[0008] Preferably, a smoking box is provided at the top of the support frame, and an exhaust fan is installed on the left side inside the smoking box.

[0009] Using the above technical solution, smoke and dust can be drawn into the smoke box by an exhaust fan.

[0010] Preferably, a pipe is connected to the right side of the smoking box, and a purification device is installed inside the smoking box.

[0011] Using the above technical solution, the smoke can be filtered and discharged through the purification device.

[0012] Preferably, the top of the smoking box is provided with a placement slot, and the interior of the placement slot is rotatably connected to a rotating shaft.

[0013] Preferably, a baffle is fixedly connected to the top of the rotating shaft, and a torsion spring is connected between the baffle and the placement groove.

[0014] Preferably, the support arm has a connecting rod slidably connected inside, and the right side of the connecting rod is connected to the laser.

[0015] Preferably, the top of the connecting rod is provided with a positioning groove, and the top of the support arm is fixedly connected to a fixing frame. The fixing frame is slidably connected to a positioning rod, and a tension spring is connected between the positioning rod and the fixing frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the rotatable laser marking machine;

[0017] 1. By setting up a small gear, a large gear, a connecting plate, a support frame, a threaded rod, a threaded block, a support arm, and a laser, the motor is started. The output end of the motor can drive the small gear and the large gear to rotate. The large gear can drive the rotating shaft, the connecting plate, and the support frame to rotate. When the support frame rotates, it can drive the support arm and the laser to rotate, thereby achieving all-round marking.

[0018] 2. By using the torsion spring, baffle, connecting rod, positioning groove, fixing frame, positioning rod, and tension spring, the exhaust fan is started, allowing the smoke and dust generated during the marking process to enter the fumigation box through the pipe and be filtered by the purification device. Rotating the baffle can separate the baffle from the purification device, making it easier to clean or replace the purification device. Pulling up the positioning rod loosens the positioning rod from the positioning groove at the connecting rod, allowing the connecting rod to slide inside the support arm, thus facilitating the extension of the laser and adjusting the position of the laser.
