Description

Technical Field

[0001] This utility model belongs to the field of laser marking machine technology, specifically relating to a laser marking machine operation protection device. Background Technology

[0002] Laser marking machines use a laser beam to create permanent marks on the surfaces of various materials. The marking effect occurs by evaporating the surface material to expose the deeper material, thus etching intricate patterns, trademarks, and text. Laser marking machines are mainly classified into CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines, and YAG laser marking machines. Laser marking machines are primarily used in applications requiring higher precision and finer details. Because laser marking involves high-temperature marking with a laser beam, careless operation can easily result in laser burns. Therefore, protective devices must be installed around the laser marking machine to prevent injuries.

[0003] Currently, Chinese patent CN216633086U discloses a protective device for a CNC laser marking machine, including a worktable. The top of the worktable is slidably connected to two surrounding panels, a and b, which surround the laser marking machine body. A protective mechanism for moving panels a and b is located on the bottom side of the worktable. A reinforcement mechanism is located on the side of the exhaust pipe. In use, operating the protective mechanism moves panels a and b in opposite directions, opening the working area of ​​the laser marking machine body for workpiece removal. Conversely, operating the protective mechanism moves panels a and b in opposite directions, protecting the working area of ​​the laser marking machine body. However, this protective device requires opening and closing every time workpieces are picked up or placed, resulting in slow marking speed and affecting the overall processing progress.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] like Figures 1 to 5 As shown, a protective device for operating a laser marking machine includes a protective shell 5 with a rectangular opening, a base plate 2 with a material feeding notch 24 fixed at the bottom of the protective shell 5, a rotating disk 3 that can be electrically driven to rotate on the upper side of the base plate 2, one end of the rotating disk 3 extending out of the protective shell 5 from the rectangular opening, and a plurality of placement holes 31 arranged in a circular array with the axis of the rotating disk 3 as the center, and a sealing component provided at the bottom of the placement holes 31, which opens when the rotating disk 3 rotates to the material feeding notch 24;

[0024] The protective shell 5 has an opening for the marking head to pass through, and the protective shell 5 is fixed with an observation window 51;

[0025] When in use, place the base plate 2 on the marking machine and insert the marking head into the protective shell 5 through the placement port. At this time, the marking head and the marking position are aligned vertically. Then, fix the base plate 2. When marking is required, the personnel place the material into the placement hole 31. At this time, another placement hole 31 is located at the material discharge notch 24. The sealing component opens and discharges the material. Then, the rotary disk 3 is electrically driven to rotate 40° or 60°, so that the corresponding placement hole 31 enters the material discharge notch 24, the marking position and the material discharge position. In this way, the material is discharged, marked and unloaded one by one.

[0026] In this embodiment, the sealing component is specifically a baffle 32. A hinge plate is fixed to one end of the baffle 32. A groove for placing the hinge plate is opened on one side of the bottom of the base plate 2. The hinge plate is hinged in the groove. The baffle 32 can rotate into the placement hole 31.

[0027] The bottom plate 2 is integrally formed with a protruding plate 22 at one end outside the protective shell 5. The material feeding notch 24 is opened on the protruding plate 22. One side of the material feeding notch 24 is a contact part 23 that abuts against the baffle 32. When the baffle 32 rotates counterclockwise, its bottom contacts the contact part 23, so that the baffle 32 gradually enters the placement hole 31.

[0028] When in use, the baffle 32 moves with the rotation of the rotating disk 3. When the baffle 32 rotates to the material discharge gap 24, under the action of gravity, the baffle 32 rotates around the hinge of the hinge plate, causing the material to fall. Then, when the rotating disk 3 continues to move, the baffle 32 contacts the contact part 23 and pushes the baffle 32 to gradually rotate into the placement hole 31.

[0029] Preferably, the hinge plate is connected to a torsion spring fixed in the groove to drive the baffle 32 to rotate and shift so that the baffle 32 is not located in the placement groove.

[0030] Preferably, the bottom of the baffle 32 is flush with the bottom of the base plate 2 to ensure that the top of the baffle 32 is level, which facilitates marking.

[0031] In this embodiment, a motor 7 is fixed on the top of the base plate 2, and a cavity is opened on the inner side of the base plate 2. Two synchronous transmission wheels 21 are rotatably connected in the cavity. The transmission wheels 21 are coaxially connected to the motor 7 and the rotating disk 3 respectively.

[0032] In use, the rotation of the rotating disk 3 is driven by the motor 7 and the transmission wheel 21 to ensure its operation;

[0033] The synchronous transmission wheels 21 can be connected by gear transmission, chain, or other structures that can achieve synchronous transmission. It should be noted that the synchronous transmission wheels 21 are existing technology, so they will not be described in detail in this embodiment.

[0034] In this embodiment, a plug-in post 33 is fixed at the bottom of the rotating disk 3, and the transmission wheel 21 that drives the rotating disk 3 has a hole for the plug-in post 33 to be inserted. The rotating disk 3 and the transmission wheel 21 are driven by the plug-in post 33.

[0035] In use, the rotating disk 3 and the transmission wheel 21 are detachably connected by the insertion post 33 and the hole on the transmission wheel 21, which makes it convenient for personnel to replace the rotating disk 3 as needed.

[0036] In this embodiment, a power interface and a button 6 are fixed to the outside of the protective shell 5. The button 6, the power interface and the motor 7 are electrically connected. When in use, a control signal is given by pressing the button 6, and the motor 7 works and rotates to a specified angle and then stops.

[0037] It should be noted that motor 7 is a servo motor 7, which is electrically connected to the microcontroller. The microcontroller has corresponding control logic, which means that when the current signal of button 6 is generated, the servo motor 7 is controlled to rotate 40° or other specified angle and then stop.

[0038] The servo motor 7 can be model JX PDI-6221MG, the microcontroller model can be STM32F407VET6 or a common 51 microcontroller, and the button 6 model can be Omron B3F-1000.

[0039] In this embodiment, a top cover 1 is fixed to the top of the protective shell 5, and an air extraction pipe 4 is fixedly connected to the top cover 1. In use, the air extraction pipe 4 is connected to an external air extraction device to extract the air inside the protective shell 5, and the air can enter from the opening in the protective shell 5.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
