However, current methods often involve manually placing the keyboard on the laser engraving area, requiring repositioning after each use, resulting in low efficiency. To address these issues, the inventor proposes a keyboard character laser engraving positioning device. Utility Model Content

[0003] To address the problem that existing keyboard laser engraving processes often involve manually placing the keyboard on the laser engraving area, requiring position adjustments after each placement, resulting in low efficiency, this invention aims to provide a keyboard character laser engraving positioning device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a keyboard character laser engraving positioning device, including a laser engraving machine and a transport cavity, wherein the transport cavity includes a conveyor belt, and the working end of the laser engraving machine faces the conveyor belt; a housing is fixedly connected to both sides of the transport cavity; a threaded cylinder is slidably connected to the upper part of the side wall of the housing; a screw is threadedly connected to the opening of the threaded cylinder; a second pulley is fixedly connected to the end of the screw away from the threaded cylinder; a clamping plate is fixedly connected to the end of the threaded cylinder; an electric push rod is embedded in both ends of the clamping plate; and an adjusting plate is fixedly connected to the output shaft end of the electric push rod.

[0005] Preferably, a motor is installed inside the transport cavity, and a rotating shaft is fixedly connected to the output shaft of the motor. A base is provided on the side wall of the motor, and the base is fixed to the inner wall of the transport cavity. The end of the rotating shaft away from the motor extends into the interior of the housing, and a first pulley is fixedly connected to the shaft end of the rotating shaft. The motor is mounted through the base, and a conveyor belt is used to transport the keyboard to be laser-engraved. The laser engraving machine includes a laser, an optical system, a motion system, a worktable, a control system, and a cooling system. The working principle of the laser engraving machine is to achieve various shapes of engraving and carving by controlling the parameters of the laser beam and the state of the material surface. When the keyboard moves to the working area of ​​the laser beam, the motor is started, and the rotating shaft can drive the first pulley to rotate under the action of the motor output shaft. A bearing seat is rotatably connected to the side wall of the screw, and the side wall of the bearing seat is fixedly connected to the inner wall of the housing. The bearing seat is used to support the screw.

[0006] Preferably, the second pulley corresponds to the first pulley, and a synchronous belt is provided on the side wall of the second pulley. The end of the synchronous belt away from the second pulley engages with the first pulley. When the first pulley rotates, the synchronous belt causes the second pulley to rotate, which in turn causes the screw to rotate. A guide plate is fixedly connected to the outer wall of the threaded cylinder, and a guide sleeve is fitted onto the side wall of the threaded cylinder. The guide sleeve has a guide groove at its opening, and the guide plate corresponds to and is slidably connected to the guide groove. A fixing plate is fixedly connected to the bottom surface of the guide sleeve, and the fixing plate is fixed to the inner wall of the housing. When the screw rotates... Through the cooperation of the screw and the threaded cylinder, and the cooperation of the guide plate and the guide groove, the threaded cylinder can be translated, which in turn allows the clamping plate to move closer to the keyboard on the conveyor belt, positioning the keyboard between two adjusting plates. Then, the electric push rod is controlled, and under the action of the output shaft of the electric push rod, the adjusting plate moves closer to the keyboard, pushing the keyboard through the adjusting plate to adjust its position so that the keyboard is in a centered position. Afterwards, the clamping plate continues to move to clamp and position the centered keyboard, so that the keyboard to be laser-engraved is stably located in the working area of ​​the laser beam.

[0007] Compared with the prior art, the advantages of this utility model are: high efficiency and accurate positioning. It eliminates the need for manual placement and adjustment of the keyboard to be laser-engraved. The keyboard can be transported by a conveyor belt. When the keyboard moves to the laser beam's working area, the adjustment plate can push the keyboard to center it in the laser beam's working area. The clamping plate can then clamp and position the centered keyboard, ensuring that the keyboard to be laser-engraved is stably located in the laser beam's working area for laser engraving.

Both sides of the transport cavity 2 are fixedly connected to a housing 5. A threaded cylinder 12 is slidably connected to the upper side wall of the housing 5. A screw 10 is threadedly connected to the opening of the threaded cylinder 12. A second pulley 9 is fixedly connected to the end of the screw 10 away from the threaded cylinder 12. A clamping plate 16 is fixedly connected to the end of the threaded cylinder 12. Electric push rods 17 are embedded in both ends of the clamping plate 16. An adjusting plate 18 is fixedly connected to the output shaft end of the electric push rod 17.

[0015] The transport cavity 2 is equipped with a motor 4. The output shaft of the motor 4 is fixedly connected to a rotating shaft 6. The side wall of the motor 4 is equipped with a base, which is fixed to the inner wall of the transport cavity 2. The end of the rotating shaft 6 away from the motor 4 extends into the interior of the housing 5, and the shaft end of the rotating shaft 6 is fixedly connected to a first pulley 7.

[0016] By adopting the above technical solution, the motor 4 is installed on the base, and the conveyor belt 3 is used to transport the keyboard to be laser-engraved. The laser engraving machine 1 includes a laser, an optical system, a motion system, a worktable, a control system, and a cooling system. The working principle of the laser engraving machine 1 is to achieve engraving and carving of various shapes by controlling the parameters of the laser beam and the state of the material surface. When the keyboard moves to the working area of ​​the laser beam, the motor 4 is started, and the rotating shaft 6 can drive the first pulley 7 to rotate under the action of the output shaft of the motor 4.

[0017] The second pulley 9 corresponds to the first pulley 7. A timing belt 8 is provided on the side wall of the second pulley 9. The end of the timing belt 8 away from the second pulley 9 is engaged with the first pulley 7.

[0018] By adopting the above technical solution, when the first pulley 7 rotates, the second pulley 9 can rotate through the synchronous belt 8, which in turn can cause the screw 10 to rotate.

[0019] A guide plate 13 is fixedly connected to the outer side wall of the threaded cylinder 12. A guide sleeve 14 is sleeved on the side wall of the threaded cylinder 12. A guide groove is provided at the opening of the guide sleeve 14. The guide plate 13 corresponds to the guide groove and is slidably connected. A fixing plate 15 is fixedly connected to the bottom surface of the guide sleeve 14. The fixing plate 15 is fixed to the inner wall of the housing 5.

[0020] By adopting the above technical solution, when the screw 10 rotates, the screw 10 and the threaded cylinder 12 cooperate with each other, and the guide plate 13 cooperates with the guide groove, so that the threaded cylinder 12 can be translated, and the clamping plate 16 can be moved to move closer to the keyboard on the conveyor belt 3, and the keyboard is positioned between the two adjusting plates 18. Then, the electric push rod 17 is controlled, and the adjusting plate 18 is moved closer to the keyboard under the action of the output shaft of the electric push rod 17. The keyboard is pushed by the adjusting plate 18, thereby adjusting the position of the keyboard so that the keyboard is in the center position.

[0023] Working principle: When in use, the keyboard to be laser-engraved is transported by the conveyor belt 3. When the keyboard moves to the working area of ​​the laser beam, the motor 4 is started. The rotating shaft 6 drives the first pulley 7 to rotate under the action of the output shaft of the motor 4. The second pulley 9 can be rotated by the synchronous belt 8, which in turn makes the screw 10 rotate. Through the cooperation between the screw 10 and the threaded cylinder 12, and the cooperation between the guide plate 13 and the guide groove, the threaded cylinder 12 can be translated, which in turn makes the clamping plate 16 move closer to the keyboard on the conveyor belt 3, and the keyboard must be positioned between the two adjusting plates 18.

[0024] Next, the electric push rod 17 is controlled, and the adjustment plate 18 is moved closer to the keyboard under the action of the output shaft of the electric push rod 17 to push the keyboard and adjust its position so that the keyboard is in the center of the laser beam working area.

[0025] Then, the motor 4 is controlled to move the clamping plate 16 to clamp and position the centered keyboard, so that the keyboard to be laser-engraved is stably located in the working area of ​​the laser beam for laser engraving.
