[0027] The present invention provides a laser marking machine 100 .

[0028] See also Figure 1 and Figure 4In one embodiment of the present utility model, the laser marking machine 100 includes a substrate 1, a height adjustment component 2, a marking device 3 and a marking platform 4; the height adjustment component 2 is connected to the substrate 1; the marking device 3 is slidably connected to the height adjustment component 2; the marking platform 4 includes a flip seat 41 and a carrier 42, the flip seat 41 is slidably connected to the substrate 1, the flip seat 41 is located on the side of the substrate 1 facing the marking device 3, the carrier 42 is rotatably connected to the flip seat 41, the carrier 42 is located between the flip seat 41 and the marking device 3, and the marking device 3 is used to output a laser beam.

[0029] In this embodiment, the substrate 1 is a key part supporting the entire system, and the substrate 1 generally needs to have good stability and rigidity to ensure accuracy during the marking process. The shape of the substrate 1 is generally not limited, and can be rectangular or circular, etc.; the substrate 1 is usually made of a solid metal material, such as aluminum alloy or steel, to provide sufficient strength and stability. In order to improve the stability of the substrate 1, reinforcing ribs may be added to the bottom or thicker materials may be used. The surface treatment of the substrate 1 is also very important, and usually anodizing or other surface treatment processes are performed to improve corrosion resistance and wear resistance. Various mounting holes or threaded holes 22a are integrated on the substrate 1 for connection with other components such as the height adjustment component 2 or the marking table 4.

[0030] Furthermore, the height adjustment component 2 is an important part of the laser marking machine 100. Its function is to adjust the height of the marking head relative to the workpiece to adapt to the marking requirements of workpieces of different thicknesses. The height adjustment component 2 usually includes a sliding mechanism and a driving mechanism, such as a sliding guide 21 or a screw rod 23 transmission mechanism. The driving mechanism can be a stepping motor or a servo motor. The height adjustment component 2 can achieve automatic focusing and automatically adjust the position of the marking head through the height signal fed back by the sensor to ensure the best marking effect. The material of the height adjustment component 2 is usually selected from high-strength, low-friction coefficient materials, such as aluminum alloy or stainless steel, to ensure its durability and stability. Sliding parts generally use self-lubricating materials or add lubricating oil grooves to reduce friction and wear.

[0031] The marking device 3 is the core component of the laser marking machine 100. It is responsible for outputting the laser beam and forming the desired graphic mark on the substrate. The marking device 3 typically consists of a laser, a focusing lens, and a galvanometer scanning system. Depending on the type of laser, it can be a CO2 laser, YAG laser, fiber laser, or semiconductor laser. The focusing lens focuses the laser beam onto the workpiece surface, achieving high-precision marking. The galvanometer scanning system controls the movement of the laser beam along a predetermined path on the workpiece, forming the desired pattern or text. The operating principles of the laser marking machine 100 can be categorized into two types: "hot processing" and "cold processing." "Hot processing" involves irradiating the material surface with a high-energy-density laser beam, causing the surface temperature to rise, resulting in melting, ablation, or evaporation, thereby forming a mark. "Cold processing" uses high-energy photons to break chemical bonds within the material or medium, achieving a non-thermal destruction process. This method has minimal impact on the material and is suitable for marking sensitive materials. The marking device 3 is suitable for marking a variety of materials, including metals, plastics, wood, glass, ceramics, and leather.

[0032] The marking table 4 is an important component of the laser marking machine 100.

The marking table 4 can accurately position the workpiece to adapt to the movement and marking path of the laser marking head. The distance between the workpiece and the laser head is adjusted by the height adjustment component 2 to ensure the best focal length and marking effect. The marking table 4 generally includes a screw 23 and a guide rail 21 to achieve precise adjustment of height and position. Some marking tables 4 may also be equipped with an electric or pneumatic lifting system to improve the efficiency and accuracy of the adjustment.

[0033] The technical solution of the present utility model is to design a laser marking machine 100, which comprises a base plate 1, a height adjustment assembly 2, a marking device 3, and a marking platform 4. The base plate 1 serves as the supporting structure of the entire laser marking machine 100, providing a stable mounting platform for the other components. The height adjustment assembly 2 is connected to the base plate 1, allowing the marking device 3 to be adjusted in the vertical direction to accommodate workpieces of varying thicknesses. Guided by the height adjustment assembly 2, the marking device 3 can be precisely moved above the workpiece for laser marking. The marking platform 4 comprises a flip seat 41 and a carrier 42. The flip seat 41 is slidably connected to the base plate 1, allowing the workpiece to be marked to move within the horizontal plane of the carrier 42 to adjust the workpiece's position. The carrier 42 is rotatably connected to the flip seat 41 and can be flipped vertically to change the orientation of the workpiece, adapting it to different marking angles. The marking device 3 laser engraves the workpiece on the carrier 42, achieving high-precision marking. By concentrating the position adjustment components such as flipping, rotation and horizontal movement on the substrate 1, the burden of the height adjustment component 2 is reduced, and the marking position is made more stable, thereby ensuring the accuracy and quality of the marking.

[0035] In one embodiment, the marking platform 4 includes a rotating motor 47 and a transmission member 48 to realize the rotation function of the carrier 42. The transmission member 48 can be a mechanical transmission mechanism such as a gear, a belt, or a sprocket, and its function is to transmit the output power of the rotating motor 47 to the carrier 42 to realize the rotation of the carrier 42. The output end of the rotating motor 47 is connected to the transmission member 48 through a key connection, a coupling or other mechanical connection method to ensure the stability and reliability of power transmission. The transmission member 48 is connected to the carrier 42, and can be directly connected or realized through a bearing, a rotating shaft or other mechanism, so that the carrier 42 can rotate around a fixed axis. During the marking process, the workpiece is placed on the carrier 42, and the rotating motor 47 drives the carrier 42 to rotate to a predetermined position through the transmission member 48 according to the instructions of the control system, so that the laser marking head can mark different surfaces of the workpiece.

[0036] In one embodiment of the present invention, please refer to Figure 2 and Figure 4 The transmission assembly 48 includes a belt 481 and a transmission wheel 482. The output end of the rotary motor 47 is connected to the transmission wheel 482.

[0039] In one embodiment, the marking platform 4 is designed to include a mounting base 49, which supports and guides the transmission assembly 48, ensuring the correct positioning and movement of the belt 481 and the drive pulley 482. The mounting base 49 is typically made of sturdy metal or engineering plastic and is designed to be fixed between the flip base 41 and the base plate 1. The connection between the mounting base 49 and the flip base 41 can be rigid or have a certain range of motion to allow for adjustment when needed. A transmission channel 49a formed within the mounting base 49 accommodates the belt 481 and the drive pulley 482. The design of the transmission channel 49a ensures the stability and protection of the belt 481 during movement. The shape and size of the transmission channel 49a should match the belt 481 and the drive pulley 482 to ensure smooth movement of the belt 481 within the transmission channel 49a. The position and positioning of the mounting base 49 ensures that the drive pulley 482 is properly aligned with the output of the rotary motor 47 and that the belt 481 is properly tensioned on the drive pulley 482.

[0040] In one embodiment of the present invention, please refer to Figure 4 The marking table 4 also includes a mounting base 49, which is connected to the flip base 41. The mounting base 49 is located between the flip base 41 and the substrate 1. A transmission channel 49a is formed in the mounting base 49, and at least part of the belt 481 and the transmission wheel 482 are located in the transmission channel 49a.

[0041] In one embodiment, the marking platform 4 is designed to include a mounting base 49, which supports and guides the transmission assembly 48, ensuring the correct positioning and movement of the belt 481 and the drive pulley 482. The mounting base 49 is typically made of sturdy metal or engineering plastic and is designed to be fixed between the flip base 41 and the base plate 1. The connection between the mounting base 49 and the flip base 41 can be rigid or have a certain range of motion to allow adjustment when needed. A transmission channel 49a formed within the mounting base 49 is used to accommodate the belt 481 and the drive pulley 482. The channel design ensures the stability and protection of the belt 481 during movement. The shape and size of the transmission channel 49a should match the belt 481 and the drive pulley 482 to ensure that the belt 481 can move smoothly within the channel. The position and positioning of the mounting base 49 ensures that the drive pulley 482 is correctly aligned with the output end of the rotary motor 47 and that the belt 481 is properly tensioned on the drive pulley 482.

[0043] In this embodiment, the rotation angle of the carrier 42 is monitored by providing a rotation angle sensor 421 to ensure that the carrier 42 rotates to a precise angle for accurate marking. The rotation angle sensor 421 can be a photoelectric encoder, a Hall effect sensor, an angular displacement sensor, or the like, capable of accurately detecting the rotation angle of the carrier 42. The rotation angle sensor 421 is mounted near the rotation axis of the carrier 42 to ensure accurate capture of the carrier 42's rotational motion. The sensor is electrically connected to the rotary motor 47 and can transmit the monitored angle information to a control system via a cable or wireless signal transmission. The signal from the rotation angle sensor 421 is sent to a control system, such as a PLC or CNC. Based on the angle information fed back by the sensor, the control system uses a control algorithm to adjust the operation of the rotary motor 47 to ensure that the carrier 42 accurately reaches the predetermined angular position. Through closed-loop control, the feedback signal from the rotation angle sensor 421 can be used to adjust the operating status of the rotary motor 47 in real time, achieving precise position control. Before marking, the control system sets the target rotation angle of the carrier 42 according to the marking program. The rotary motor 47 drives the stage 42 to rotate, while the rotation angle sensor 421 monitors the actual rotation angle and feeds the data back to the control system. The control system compares the target angle with the actual angle and adjusts the motor operation until the stage 42 reaches the set angle.

[0044] In one embodiment of the present invention, please refer to Figure 4The marking platform 4 further includes a flip motor 44 and a reducer 45 . The reducer 45 is connected to the output end of the flip motor 44 and the flip seat 41 . The reducer 45 is located on one side of the flip seat 41 .

[0045] In this embodiment, the marking table 4 also includes a flip motor 44 and a reducer 45 connected to its output end, and the reducer 45 is used to reduce the high-speed output of the flip motor 44 to the low-speed rotation required by the flip seat 41. Specifically, according to the rotational speed of the flip motor 44 and the rotational speed required by the flip seat 41, a reducer 45 with a suitable reduction ratio is matched, usually a planetary gear reducer 45 or a worm gear reducer 45, to achieve precise speed reduction and torque increase. The input end of the reducer 45 is connected to the output shaft of the flip motor 44 through a coupling, a key connection or other mechanical connection method to ensure the stability of power transmission. Appropriate protective covers can also be set around the flip motor 44 and the reducer 45 to prevent accidental contact and dust accumulation, thereby ensuring the safety of the operator and the long-term stable operation of the equipment.

[0046] In one embodiment of the present invention, please refer to Figure 4 The reducer 45 is provided with a flip angle sensor 451 . The flip angle sensor 451 is used to monitor the flip angle of the flip seat 41 in real time. The flip angle sensor 451 is electrically connected to the flip motor 44 .

[0047] In one embodiment, a flip angle sensor 451 is provided on the reducer 45, and the sensor is used to monitor the flip angle of the flip seat 41 in real time. The sensor can be a photoelectric encoder, a Hall effect sensor, or other types of displacement sensors. The flip angle sensor 451 is electrically connected to the flip motor 44, which can be achieved through appropriate cables and connectors to ensure that the sensor signal can be accurately transmitted to the control unit. The sensor signal is sent to the control system, and the control system adjusts the operation of the flip motor 44 through a control algorithm based on the angle information fed back by the sensor to ensure that the flip seat 41 accurately reaches the predetermined angular position. Ensure that the reducer 45 and the sensor are fixed in the appropriate position, fixed with necessary fasteners, and adjusted horizontally and coaxially to ensure smooth operation and accuracy.

[0048] In one embodiment of the present invention, please refer to Figure 4 The carrier 42 is provided with a placement groove 42 a, and the placement groove 42 a is located on a side of the carrier 42 facing the marking device 3.

[0049] In one embodiment, the carrier 42 is provided with a placement groove 42a designed to ensure stable placement of the workpiece during the marking process. The design of the placement groove 42a should be determined based on the size and shape of common workpieces to ensure that the workpiece can be stably placed on the carrier 42. The placement groove 42a is typically designed as a groove that mates with the flat surface of the carrier 42 to secure the workpiece's position. The placement groove 42a is located on the side of the carrier 42 facing the marking device 3. This design ensures that the workpiece is in the path of the laser beam of the marking device 3. The size and shape of the placement groove 42a should match the bottom contour of the workpiece to provide sufficient support and stability. The placement groove 42a also prevents the workpiece from moving or vibrating during the marking process. The placement groove 42a should be made of the same material as the carrier 42, typically metal or engineering plastic, to ensure wear resistance and stability. The design of the placement groove 42a should take into account the operator's convenience, ensuring that the placement and removal of the workpiece are convenient and quick.

[0050] In one embodiment of the present invention, please refer to Figure 2 and Figure 4 The marking platform 4 further includes a vacuum generator 46 , a negative pressure hole is opened on the bottom wall of the placement groove 42 a , and the output end of the vacuum generator 46 is connected to the negative pressure hole.

[0051] In this embodiment, the marking platform 4 also includes a vacuum generator 46. A negative pressure hole is defined in the bottom wall of the placement slot 42a. The output of the vacuum generator 46 is connected to the negative pressure hole to ensure stable positioning of the workpiece during the marking process. The vacuum generator 46 is mounted near the marking platform 4 and generates negative pressure to secure the workpiece through suction. The output of the vacuum generator 46 is connected to the negative pressure hole in the placement slot 42a via a pipe or hose. The placement slot 42a is defined on the bottom wall of the platform 42, on the side of the platform 42 facing the marking device 3. The slot is designed to ensure that the workpiece can be accurately placed in the appropriate position and that the workpiece is securely held when the negative pressure is activated. A negative pressure hole is defined in the bottom wall of the placement slot 42a and is connected to the output of the vacuum generator 46. The negative pressure hole is designed to ensure that air can be effectively extracted, thereby creating a negative pressure area within the slot. To enable automated control, a flip angle sensor 451 monitors the flip angle of the flip seat 41 and transmits the data to the control system. The control system precisely controls the workpiece's suction and release by controlling the start and stop of the vacuum generator 46 based on feedback from the sensor. Before marking, the workpiece is placed in the placement slot 42a. The flip motor 44 flips the workpiece to the appropriate position based on instructions from the flip angle sensor 451. Subsequently, the vacuum generator 46 activates, generating negative pressure through the negative pressure holes, firmly adsorbing the workpiece within the slot. After marking is complete, the control system instructs the vacuum generator 46 to stop, releasing the workpiece, which can then be removed.

[0053] In this embodiment, the design of the height adjustment assembly 2 combines a guide rail 21, a screw rod 23 and a connecting seat 22 to achieve precise height adjustment of the marking device 3 in the vertical direction. Specifically, the guide rail 21 usually adopts a high-precision linear guide rail 21 to ensure the smoothness and accuracy of the vertical movement. The guide rail 21 is connected to the base plate 1 and extends vertically to provide a stable vertical movement path for the marking device 3. The connecting seat 22 is designed to be slidably connected to the guide rail 21, usually through a slider 221.

The slider 221 is slidably connected to the guide rail 21, allowing the connecting seat 22 to move up and down along the guide rail 21. The design of the slider 221 is to ensure the smoothness and accuracy of the movement of the connecting seat 22. The screw rod 23 usually uses a ball screw 23 to provide high-precision and low-friction transmission. The threaded hole 22a on the connecting base 22 matches the thread of the screw rod 23. The screw rod 23 is screwed to the connecting base 22 through the threaded hole 22a. The rotation of the screw rod 23 can be converted into linear motion of the connecting base 22.
