[0001] This invention relates to the field of laser marking machine technology, specifically a laser marking machine for processing motorcycle parts. Background Technology

[0002] Laser marking machines used in motorcycle parts processing are mainly used for high-precision marking, coding, and engraving on materials such as metals and plastics.

[0003] Patent publication number CN215658448U relates to a laser marking machine for processing motorcycle parts, comprising a laser marking machine body, a moving mechanism, a CNC panel, and an adjustment knob. The moving mechanism is located inside the laser marking machine body. The CNC panel and adjustment knob are mounted on the upper part of the laser marking machine body. A fixed base is fixed to one side of the CNC panel, and rotating grooves are formed on both the upper and lower sides of the inner wall of the fixed base. Through the coordinated arrangement of the fixed base, rotating grooves, rotating rod, torsion spring, protective cover, handle, and observation window, accidental contact with the CNC panel and adjustment knob is effectively prevented, ensuring the normal operation of the laser marking machine body. Furthermore, the observation window on the protective cover allows operators to directly observe the parameters on the CNC panel from outside the protective cover, improving the convenience of the device.

[0004] In the aforementioned patent, the observation window set on the protective cover allows the staff to directly observe the parameters on the CNC panel from outside the protective cover, improving the convenience of the device. However, deviations may occur during the placement of parts, which may cause the position to shift during the marking process and affect the printing effect. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a laser marking machine for processing motorcycle parts, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a laser marking machine for processing motorcycle parts, comprising: an operating table; a linear motor, the linear motor being fixedly mounted on the top of the operating table; a laser marking device, the laser marking device being fixedly mounted on the output end of the linear motor, the linear motor being used to drive the laser marking device to move up and down; a display screen, the display screen being fixedly mounted on the surface of the linear motor; a protective plate, the protective plate being fixedly mounted on the top of the operating table, the protective plate being used to protect the operating table; a spiral rotating rod is rotatably mounted inside the operating table, the surface of the spiral rotating rod having two spiral grooves, the spiral grooves rotating in opposite directions. The spiral rotor is driven by a motor. A movable block is threaded onto the surface of the spiral rotor. The movable block is slidably mounted on the inner wall of the operating table. A clamping plate is fixedly mounted on the top of the movable block. A square plate is fixedly mounted on the surface of the movable block. A fixing rod is fixedly mounted on the top of the square plate. A pulley frame is fixedly mounted on the surface of the fixing rod. A straightening plate is slidably mounted on the top of the protective plate. First, the motorcycle part to be marked is placed on the protective plate. Then, the content to be printed is adjusted on the display screen. After confirmation, the motor is started. The rotation of the motor drives the spiral rotor to rotate. The rotation of the spiral rotor drives the two movable blocks to move towards each other. The movement of the movable blocks towards each other drives the clamping plate to move towards each other.

[0007] According to the above technical solution, a connecting plate is fixedly installed at the bottom of the correction plate, a sliding frame is slidably installed on the inner wall of the protective plate, a triangular block is fixedly installed on the surface of the sliding frame, a triangular plate is slidably installed on the inner wall of the protective plate, an arc-shaped plate is fixedly installed on the top of the triangular plate, a return spring is provided between the protective plate and the triangular plate, an inclined surface is provided on the side of the correction plate near the pulley frame, and a first spring is provided between the protective plate and the correction plate. When the sliding frame moves upward, it will push the triangular plate to move away from the sliding frame. When the triangular plate moves away from the sliding frame, it will drive the arc-shaped plate to move away from the sliding frame. When the correction plate is separated from the pulley frame, the elastic force of the first spring will drive the correction plate to return to its original position.

[0008] According to the above technical solution, the top of the fixing rod is provided with a cleaning device for cleaning impurities and a protective device for protecting the laser marking equipment. The cleaning device includes a fixing block, a connecting frame, and a cleaning brush. The fixing block moves closer to the motorcycle parts by moving the fixing rod, which in turn moves the connecting frame closer to the motorcycle parts. The fixing block is fixedly installed on the top of the fixing rod, the connecting frame is fixedly installed on the surface of the fixing block, and the cleaning brush is fixedly installed on the surface of the connecting frame.

[0009] According to the above technical solution, a connecting rod is fixedly installed on the surface of the connecting frame, a pressure box is fixedly installed on the top of the protective plate, a pressure plate is fixedly installed on the end of the connecting rod away from the connecting frame, the pressure plate is slidably installed on the inner wall of the pressure box, and an air outlet is opened on the surface of the pressure box. When the pressure plate moves towards the motorcycle parts, it will squeeze the gas inside the pressure box and spray it out through the air outlet.

[0010] According to the above technical solution, a soft brush is provided at the bottom of the cleaning brush to clean impurities adhering to the motorcycle parts. A second spring is provided between the air pressure plate and the air pressure box to drive the air pressure plate to reset.

[0011] According to the above technical solution, the protective device includes an L-shaped rod, a roller, and a trapezoidal plate. The L-shaped rod moves towards the motorcycle parts via the moving of the connecting frame. The moving of the L-shaped rod towards the motorcycle parts causes the roller to move towards the motorcycle parts. The moving of the roller towards the motorcycle parts pushes the trapezoidal plate downward. The L-shaped rod is fixedly installed on the surface of the connecting frame, the roller is rotatably installed on the surface of the L-shaped rod, and the trapezoidal plate is slidably installed on the surface of the pressure box.

[0012] According to the above technical solution, a long rod is fixedly installed on the top of the connecting rod, a U-shaped frame is slidably installed on the bottom of the laser marking equipment, a fixing plate is fixedly installed on the surface of the U-shaped frame, a rotating rod is rotatably installed on the bottom of the laser marking equipment, and a baffle is fixedly installed on the surface of the rotating rod. When the U-shaped frame moves away from the long rod, it will push the rotating rod to rotate away from the long rod. When the rotating rod rotates away from the long rod, it will drive the baffle to rotate away from the long rod.

[0013] According to the above technical solution, a No. 3 spring is provided between the trapezoidal plate and the air pressure box. When the trapezoidal plate is separated from the roller, the elastic force of the No. 3 spring will drive the trapezoidal plate to reset. A No. 4 spring is provided between the laser marking device and the U-shaped frame. When the long rod is separated from the fixed plate, the elastic force of the No. 4 spring will drive the U-shaped frame to reset. A No. 1 torsion spring is provided between the laser marking device and the rotating rod. When the U-shaped frame is separated from the rotating rod, the elastic force of the No. 1 torsion spring will drive the rotating rod to reset.

[0014] This invention provides a laser marking machine for processing motorcycle parts. It has the following advantages:

[0015] (1) This invention uses a clamping plate to hold the motorcycle parts, preventing the motorcycle parts from shifting during the laser printing process, which would cause the printing to deviate and affect the laser marking effect. By correcting the position of the motorcycle parts before clamping them, it can effectively prevent the position of the motorcycle parts from deviating during clamping, which would cause the clamping plate to damage the surface of the motorcycle parts and affect the normal use of the motorcycle parts. The arc plate supports the inner wall of the motorcycle parts to prevent slight deformation due to uneven heating, which may cause the entire part to become unbalanced and affect the laser marking effect. The support can maintain the stability of the workpiece and avoid bending or deformation during the marking process, ensuring the marking quality and accuracy.

[0016] (2) The invention uses a soft brush to scrape away dust or impurities adhering to the motorcycle parts by moving it closer to the motorcycle parts, preventing surface impurities from causing laser beam scattering and reducing the focusing accuracy of the laser beam, thereby affecting the details and clarity of the marking. At the same time, gas is sprayed out through the air outlet to work with the soft brush to remove dust and impurities adhering to the motorcycle parts, preventing the laser beam from not being able to act evenly on the surface of the workpiece during laser marking, resulting in unclear or incomplete marking.

[0017] (3) In this invention, the trapezoidal plate moves downward and gradually covers the air outlet, making the air outlet smaller and the gas ejected more powerful. By gradually increasing the wind force, the direction of dust blowing can be more effectively controlled to avoid polluting the surrounding environment. At the same time, the rotating rod rotates away from the long rod, which will drive the baffle to rotate away from the long rod. The bottom of the laser marking equipment is opened by the baffle moving away from the long rod, preventing long-term exposure to the air from causing the lens coating to age, fade or become brittle, reducing the optical performance and service life of the lens.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-4 One embodiment of the present invention is: a laser marking machine for processing motorcycle parts, comprising: an operating table 1; a linear motor 2, the linear motor 2 being fixedly installed on the top of the operating table 1; a laser marking device 3, the laser marking device 3 being fixedly installed at the output end of the linear motor 2, the linear motor 2 being used to drive the laser marking device 3 to move up and down; a display screen 4, the display screen 4 being fixedly installed on the surface of the linear motor 2; a protective plate 5, the protective plate 5 being fixedly installed on the top of the operating table 1, the protective plate 5 being used to protect the operating table 1; and a spiral rotating rod 6 being rotatably installed inside the operating table 1. The surface of the spiral rod 6 has two spiral grooves with opposite directions. The spiral rod 6 is driven by a motor. A moving block 7 is threaded on the surface of the spiral rod 6. The moving block 7 is slidably installed on the inner wall of the operating table 1. A clamping plate 8 is fixedly installed on the top of the moving block 7. A square plate 9 is fixedly installed on the surface of the moving block 7. A fixing rod 10 is fixedly installed on the top of the square plate 9. A pulley frame 11 is fixedly installed on the surface of the fixing rod 10. A straightening plate 12 is slidably installed on the top of the protective plate 5 to prevent the motorcycle parts from shifting during the laser printing process, which would cause the printing to deviate and affect the laser marking effect.

[0029] A connecting plate 121 is fixedly installed at the bottom of the straightening plate 12. A sliding frame 123 is slidably installed on the inner wall of the protective plate 5. A triangular block 122 is fixedly installed on the surface of the sliding frame 123. A triangular plate 124 is slidably installed on the inner wall of the protective plate 5. An arc plate 125 is fixedly installed on the top of the triangular plate 124. A return spring is provided between the protective plate 5 and the triangular plate 124. When the triangular plate 124 is disengaged from the sliding frame 123, the return spring itself will drive the triangular plate 124 to return to its original position. The side of the straightening plate 12 near the pulley frame 11 is provided with an inclined surface. A first spring is provided between the protective plate 5 and the straightening plate 12. When the straightening plate 12 is disengaged from the pulley frame 11, the first spring itself will drive the straightening plate 12 to return to its original position. The support can maintain the stability of the workpiece, avoid bending or deformation during the marking process, and ensure the marking quality and accuracy.

[0030] In this embodiment, the motorcycle part to be marked is first placed on the protective plate 5. Then, the content to be printed is adjusted on the display screen 4. Once confirmed, the motor is started. The motor rotation drives the spiral rod 6 to rotate, which in turn drives two moving blocks 7 to move towards each other. The moving blocks 7 move towards each other, which in turn drives the clamping plate 8 to move towards each other. The clamping plate 8 then contacts the motorcycle part, holding it in place to prevent displacement of the motorcycle part during laser printing, which would cause printing deviation and affect the laser marking effect. At the same time, the moving blocks 7 move towards each other, which drives the square plate 9 to move towards each other. The square plate 9 moves towards each other, which in turn drives the fixing rod 10 to move towards each other. The fixing rod 10 moves towards each other, which drives the pulley frame 11 to move towards each other. During the movement of the pulley frame 11, it contacts the inclined surface of the straightening plate 12, which pushes the straightening plate 12 closer to the motorcycle part. This corrects the position of the motorcycle part before clamping it with the clamping plate 8. To prevent misalignment of motorcycle parts during clamping, which could damage the surface of the motorcycle parts and affect their normal use, the clamping plate 8 is designed to support the inner wall of the motorcycle parts. This prevents slight deformation due to uneven heating, which could lead to imbalance of the entire part and affect the laser marking effect. The support also maintains the stability of the workpiece, preventing bending or deformation during marking and ensuring the marking quality and accuracy.

[0031] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the top of the fixing rod 10 is provided with a cleaning device for cleaning impurities and a protective device for protecting the laser marking equipment 3. The cleaning device includes a fixing block 131, a connecting frame 132 and a cleaning brush 133. The fixing block 131 is fixedly installed on the top of the fixing rod 10, the connecting frame 132 is fixedly installed on the surface of the fixing block 131, and the cleaning brush 133 is fixedly installed on the surface of the connecting frame 132. The soft brush moves towards the motorcycle parts to scrape off the dust or impurities adhering to the motorcycle parts, preventing surface impurities from causing laser beam scattering, reducing the focusing accuracy of the laser beam, and thus affecting the details and clarity of the marking.

[0032] A connecting rod 134 is fixedly installed on the surface of the connecting frame 132, and a pressure box 135 is fixedly installed on the top of the protective plate 5. A pressure plate 136 is fixedly installed on the end of the connecting rod 134 away from the connecting frame 132. The pressure plate 136 is slidably installed on the inner wall of the pressure box 135. An air outlet 137 is opened on the surface of the pressure box 135. Gas is sprayed out through the air outlet 137 to work with a soft brush to remove dust and impurities adhering to the motorcycle parts, preventing the laser beam from not being able to act evenly on the workpiece surface during laser marking, resulting in unclear or incomplete marking.

[0033] The bottom of the cleaning brush 133 is equipped with a soft brush to clean impurities adhering to the motorcycle parts. A second spring is installed between the air pressure plate 136 and the air pressure box 135, which drives the air pressure plate 136 to reset.

[0034] The protective device includes an L-shaped rod 141, a roller 142, and a trapezoidal plate 143. The L-shaped rod 141 is fixedly installed on the surface of the connecting frame 132, the roller 142 is rotatably installed on the surface of the L-shaped rod 141, and the trapezoidal plate 143 is slidably installed on the surface of the pressure box 135. By gradually increasing the wind force, the direction of dust dispersion can be more effectively controlled to avoid polluting the surrounding environment.

[0035] A long rod 144 is fixedly installed on the top of the connecting rod 134. A U-shaped frame 145 is slidably installed on the bottom of the laser marking device 3. A fixing plate 146 is fixedly installed on the surface of the U-shaped frame 145. A rotating rod 147 is rotatably installed on the bottom of the laser marking device 3. A baffle 148 is fixedly installed on the surface of the rotating rod 147. The bottom of the laser marking device 3 is opened by the baffle 148 in the direction away from the long rod 144 to prevent long-term exposure to air from causing the lens coating to age, fade or become brittle, thereby reducing the optical performance and service life of the lens.

[0036] A No. 3 spring is installed between the trapezoidal plate 143 and the air pressure box 135. When the trapezoidal plate 143 is separated from the roller 142, the elastic force of the No. 3 spring will drive the trapezoidal plate 143 to reset. A No. 4 spring is installed between the laser marking device 3 and the U-shaped frame 145. When the long rod 144 is separated from the fixed plate 146, the elastic force of the No. 4 spring will drive the U-shaped frame 145 to reset. A No. 1 torsion spring is installed between the laser marking device 3 and the rotating rod 147. When the U-shaped frame 145 is separated from the rotating rod 147, the elastic force of the No. 1 torsion spring will drive the rotating rod 147 to reset.

[0037] In this embodiment, during operation: the fixed rod 10 moves towards the motorcycle parts, causing the fixed block 131 to move towards the motorcycle parts. The movement of the fixed block 131 towards the motorcycle parts causes the connecting frame 132 to move towards the motorcycle parts. The movement of the connecting frame 132 towards the motorcycle parts causes the cleaning brush 133 to move towards the motorcycle parts. The movement of the cleaning brush 133 towards the motorcycle parts causes the soft brush to move towards the motorcycle parts. The movement of the soft brush towards the motorcycle parts removes dust or impurities adhering to the motorcycle parts, preventing surface impurities from causing laser beam scattering and reducing... The low focusing accuracy of the laser beam affects the detail and clarity of the marking. At the same time, the movement of the connecting bracket 132 towards the motorcycle part will drive the connecting rod 134 towards the motorcycle part. The movement of the connecting rod 134 towards the motorcycle part will drive the air pressure plate 136 towards the motorcycle part. The movement of the air pressure plate 136 towards the motorcycle part will compress the gas inside the air pressure box 135 and eject it through the air outlet 137. The gas ejected through the air outlet 137, together with the soft brush, removes the dust and impurities adhering to the motorcycle part, preventing the laser beam from not being able to act evenly on the workpiece surface during laser marking, resulting in unclear or incomplete marking.

[0038] The movement of the connecting bracket 132 towards the motorcycle parts causes the L-shaped rod 141 to move towards the motorcycle parts. This movement of the L-shaped rod 141, in turn, causes the roller 142 to move towards the motorcycle parts. The roller 142 then pushes the trapezoidal plate 143 downwards, gradually covering the air outlet 137. A smaller air outlet 137 results in a stronger exhaust. By gradually increasing the airflow, the direction of dust dispersion can be more effectively controlled, preventing environmental pollution. Simultaneously, the movement of the connecting rod 134 towards the motorcycle parts causes the long rod 144 to move towards the motorcycle parts. The movement of the long rod 144 toward the motorcycle parts will push the fixing plate 146 away from the long rod 144. The movement of the fixing plate 146 away from the long rod 144 will drive the U-shaped frame 145 away from the long rod 144. The movement of the U-shaped frame 145 away from the long rod 144 will push the rotating rod 147 away from the long rod 144 to rotate. The rotation of the rotating rod 147 away from the long rod 144 will drive the baffle 148 away from the long rod 144 to rotate. The movement of the baffle 148 away from the long rod 144 will open the bottom of the laser marking equipment 3, preventing long-term exposure to air from causing the lens coating to age, fade, or become brittle, thus reducing the optical performance and service life of the lens.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
