Description

Technical Field

[0001] This invention relates to the field of notebook computer marking technology, specifically to a laser marking device for auxiliary positioning of notebook computer casing. Background Art

[0002] To ensure accurate positioning and consistency in the marking process on laptop casings, laser marking technology is widely used in industries such as electronics, automotive parts, and aerospace. It can provide precise markings such as serial numbers, company logos, and QR codes. Laptop casing auxiliary positioning laser marking devices improve production efficiency while ensuring accuracy, making them an indispensable piece of equipment in modern manufacturing.

[0003] Patent CN215545852U discloses a marking machine for processing laptop casings, including a marking machine, a chassis, and a feeding plate. The marking machine is fixedly connected to the right side of the top rear side of the chassis, and the right side of the feeding plate is fixedly connected to the top left side of the chassis. This patent, by setting a pushing component, can move the baffle to the left via a transmission mechanism, pushing the marked material onto the feeding plate. Simultaneously, heat dissipation holes and a cooling fan can dissipate heat from the internal components, preventing overheating of the chassis or marking machine that could melt the wires and cause a short circuit. This solves the problem of existing laptop laser marking machines requiring manual alignment, positioning, and fixing before marking, followed by removing the fixed laptop casing for the next marking cycle, which is cumbersome and slow. It offers the advantage of automatic feeding and unloading. However, this patent also has the problem of dust adhering to the laser lens, causing wear and requiring regular maintenance. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a laser marking device for auxiliary positioning of laptop shells, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a laser marking device for auxiliary positioning of a laptop shell, comprising a frame, a side plate fixedly connected to the side of the frame, a platform fixedly connected to the top surface of the frame, a conveyor belt installed below the platform, a laser marking mechanism provided on the top surface of the rear end of the frame, an alignment calibration mechanism provided on the top surface of the front end of the frame, and a positioning buffer mechanism provided on the rear side of the laser marking mechanism;

[0006] The laser marking mechanism includes a base, a flipping arm rotatably connected to the inner side of the base, a pressure rod slidably connected to the top of the flipping arm, a connecting rod seat fixedly connected to the outer surface of the pressure rod, a lifting plate fixedly connected to the bottom end of the connecting rod seat, four vertical sliding rods slidably passing through the surface of the lifting plate, and a laser lens installed on the bottom surface of the lifting plate.

[0007] According to the above technical solution, a vertical guide block is slidably connected to the side of the lifting plate away from the tilting arm, and an air chamber is fixedly connected to the side of the vertical guide block away from the lifting plate. A lower pressure cylinder is slidably connected to the top of the air chamber, an upper push rod is slidably connected to the inner wall of the lower pressure cylinder, a one-way flap is provided above the upper push rod, an oil supply pipe is fixedly connected to the outer wall of the lower pressure cylinder, an oil discharge pipe is fixedly connected to the top of the lower pressure cylinder, an air intake groove is provided on the outer side of the laser lens, an air supply pipe is fixedly connected to the top of the air intake groove, a dust collection cone is fixedly connected inside the air intake groove, an elastic cover is fixedly connected to the top of the dust collection cone, a blocking plate is provided below the elastic cover, and an air blowing pipe is fixedly connected to the bottom end of the blocking plate.

[0008] According to the above technical solution, the base is fixedly connected to the platform, the four vertical sliding rods are fixedly connected to the platform, the vertical guide block is fixedly connected to the platform, an oil tank is provided inside the vertical guide block, the upper push rod is fixedly connected to the air chamber, the one-way vane is fixedly connected to the inner wall of the lower pressure cylinder, the oil discharge pipe is interconnected with the inside of the lower pressure cylinder, the oil delivery pipe is interconnected with the inside of the lower pressure cylinder, the end of the oil delivery pipe away from the lower pressure cylinder is connected to the oil tank, a piston is fixedly connected to the bottom end of the lower pressure cylinder, and the piston is slidably connected to the air chamber, and the air intake groove pipe is fixedly connected to the lifting plate. Next, the end of the air supply pipe away from the air intake slot pipe slides through into the air chamber and is fixedly connected to the piston. The blocking plate is fixedly connected to the blowing pipe. The blowing pipe is unidirectionally connected from the inside of the air intake slot pipe to the outside of the air intake slot pipe. The rotating arm is driven by the built-in motor to rotate around the platform, so that the rotating arm rotates and applies downward pressure to the pressure rod. After the pressure rod is subjected to force, it pushes the connected linkage seat to move. The linkage seat causes the lifting plate to move downward along the vertical slide rod, so that the laser lens connected to the bottom side of the lifting plate is close to the part that needs to be marked below. During this process, the downward movement of the lifting plate drives the connected downward pressure. The cylinder pushes the bottom piston to slide along the inner wall of the air chamber, expelling the air from the chamber through the air supply pipe connected to the piston. At this time, the air supply pipe moves with the lower cylinder and slides along with the air chamber. The air expelled through the air supply pipe is delivered into the connected air intake pipe, causing the air-blowing baffle to bend downwards and create a gap with the inner wall of the air blowing pipe. Air is then expelled from the air blowing pipe through this gap. Additionally, the oil tank built into the vertical guide block discharges oil into the lower cylinder through a connected oil supply pipe. As the lower cylinder moves downwards, it approaches the upper push rod. The upper push rod compresses the space inside the lower cylinder, forcing lubricant through the one-way vane. The lubricant is discharged from the flap, leaving it above the one-way flap and in the connected oil drain pipe. When the lubricant in the oil drain pipe accumulates to a certain amount, it can lubricate the rotating shaft of the tilting arm, thereby reducing wear on parts and extending the service life of the parts. At the same time, when the lower cylinder moves upward, it drives the piston to draw outside air into the air chamber. The outside air draws away the dust attached to the laser lens through the air intake pipe, and the dust is carried by the air through the dust collection cone in the air intake pipe. The air pushes open the elastic cover on the dust collection cone and allows the air to enter the air chamber through the connected air supply pipe.

[0009] According to the above technical solution, the alignment and calibration mechanism includes a pull-down folding plate, an elastic frame is provided below the pull-down folding plate, a cross frame is fixedly connected to the front side of the elastic frame, an inclined slot plate is fixedly connected to the inner side of the cross frame, an upper slot plate is provided to the front side of the inclined slot plate, a vertical slide plate is fixedly connected to the front side of the upper slot plate, and a bent slide rod is slidably connected between the upper slot plate and the inclined slot plate.

[0010] According to the above technical solution, a guide plate is slidably connected to the middle position of the bent slide rod, and two hinged connecting rods are hinged to the end of the bent slide rod away from the upper groove plate. A pull rod is fixedly connected to the end of each hinged connecting rod away from the bent slide rod, and a connecting rod cross plate is rotatably connected to the top of each pull rod. A fixing strip is slidably connected to one side of the connecting rod cross plate, and a telescopic push plate is provided on the side of the connecting rod cross plate away from the fixing strip.

[0011] According to the above technical solution, the pull-down folding plate is slidably connected to the platform, a tension spring is provided between the pull-down folding plate and the elastic frame, and the two ends of the tension spring are respectively connected to the pull-down folding plate and the elastic frame, the upper groove plate is slidably connected to the horizontal frame, and a return spring is provided on the front side of the vertical slide plate, and the two ends of the return spring are respectively fixedly connected to the vertical slide plate and the horizontal frame.

[0012] According to the above technical solution, the guide plate is fixedly connected to the conveyor belt, the pull rod is slidably connected to the platform, the fixing strip is fixedly connected to the platform, and a spring plate is provided between the telescopic push plate and the connecting rod cross plate, with both ends of the spring plate fixedly connected to the telescopic push plate and the connecting rod cross plate respectively. The telescopic push plate is a telescopic structure composed of a narrow plate and a wide plate. When the tilting arm rotates around the platform, the bottom end of the tilting arm applies pressure to the elastic frame, causing the elastic frame to pull the lower folding plate downward through the tension spring. The movement of the elastic frame drives the connected cross plate and inclined trough plate to move downward, causing the inclined trough plate and upper trough plate to move downward. During the process, pressure is applied to the bent slide bar, causing it to pull the connected hinged rod along the guide plate. In this process, the upper trough plate first slides along the cross frame through the connected vertical slide plate, squeezing the return spring. When the return spring is compressed and contracts, the spring force provides support to the vertical slide plate, allowing the vertical slide plate to pull the bent slide bar along the guide plate through the connected upper trough plate. The guide plate pulls the hinged rod, causing the connecting rod to pull the connecting rod cross plate to slide along the fixed bar. The fixed bar then pushes the telescopic push plate connected to the spring plate, bringing the two telescopic push plates closer together and centering the accessories on the conveyor belt.

[0013] According to the above technical solution, the positioning buffer mechanism includes a pressure plate, and two sliding grooves are provided above the pressure plate. A pressure strip is fixedly connected to the top surface of each sliding groove, and a bent connecting rod is fixedly connected to the front surface of the sliding groove.

[0014] According to the above technical solution, the rear side of the pressure plate is fixedly connected with a connecting cable, the rear side of the platform is provided with a feeding trough, the side of the feeding trough is rotatably connected with a flip handle, and the bottom end of the flip handle is fixedly connected with a buffer flap.

[0015] According to the above technical solution, the pressure plate is fixedly connected to the pull-down folding plate, the end of the bending connecting rod away from the slide rail is fixedly connected to the telescopic push plate, the feeding chute is fixedly connected to the side plate, and the end of the connecting cable away from the pressure plate slides through the frame and is fixedly connected to the flipping handle. The flipping arm flips and pushes the elastic frame to pull the tension spring, causing the pull-down folding plate to slide downwards along the frame. The movement of the pull-down folding plate causes the connected pressure plate to slide downwards along the vertical slide bar. The pressure plate, through the connected slide rail, causes the pressure strip to move downwards together. The movement of the telescopic push plate drives the connected bending connecting rod, causing the bending connecting rod to move the slide rail. Sliding along the horizontal groove on the pressure plate, the sliding groove bar moves the connected pressure strip to adapt to the width of the accessory. As the pressure plate falls, the pressure strip applies pressure to the edge of the accessory. At this time, the elastic frame continues to move downward, pulling the tension spring to deform, while the pull-down folding plate stops moving. The width of the accessory is measured by the telescopic push plate to help adjust the position of the pressure strip. At the same time, when the pressure plate returns to its original position, it pulls the connecting cable, causing the connecting cable to rotate the flip handle around the connection point of the feed chute. The flip handle causes the buffer flap to tilt up, and the buffer flap consumes the potential energy generated by the accessory sliding down the feed chute.

[0016] This invention provides a laser marking device for auxiliary positioning on a laptop casing. It has the following advantages:

[0017] This invention comprises a vertical sliding rod, a lower pressure cylinder, an air chamber, an air intake tube, an upper push rod, a one-way flap, an air supply pipe, an oil supply pipe, an oil discharge pipe, a dust collection cone, an elastic cover, a blocking plate, and an air blowing pipe. Air is discharged through the air blowing pipe through gaps. The discharged air blows away the dust adhering to the parts to be marked, preventing dust from affecting the clarity of the marking. At the same time, the air is used to push open the elastic cover on the dust collection cone, allowing air to enter the air chamber through the connected air supply pipe. This prevents scratches caused by regular lens wiping and avoids dust adhering to the lens without timely cleaning, which may cause lens damage, increase equipment maintenance costs, or shorten the lens's lifespan.

[0018] This invention comprises a pull-down folding plate, an elastic frame, a horizontal frame, an inclined groove plate, an upper groove plate, a vertical slide plate, a bent slide rod, a guide plate, a hinged connecting rod, a pull rod, a fixing bar, a connecting rod horizontal plate, and a telescopic push plate. The fixing bar pushes the telescopic push plate connected by spring plates, bringing the two telescopic push plates closer together to center the accessories on the conveyor belt. When the telescopic push plate contacts the accessories, it compresses the spring plates to deform, preventing the accessories from being deformed due to continuous pushing. By adjusting the placement of the accessories on the conveyor belt, the placement position is prevented from affecting the laser marking position and thus the laser marking effect.

[0019] This invention, by setting up a pressure plate, a sliding groove bar, a pressure strip, a bending connecting rod, a connecting cable, a feeding groove, a flip handle, and a buffer flap, adjusts the position of the pressure strip to press against the edge of the part, preventing the pressure strip from obstructing the marking position and preventing displacement of the part during laser marking. At the same time, the flip handle drives the buffer flap to tilt up, which consumes the potential energy generated by the part sliding down the feeding groove, thereby preventing the part from falling down the feeding groove and causing collisions. It can buffer the part from sliding down and causing collisions. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Please see Figure 1-10 An embodiment of the present invention is as follows: a laser marking device for auxiliary positioning of a notebook shell, including a frame 1, a side plate 2 fixedly connected to the side of the frame 1, a platform 3 fixedly connected to the top surface of the frame 1, a conveyor belt 4 installed below the platform 3, a laser marking mechanism 5 provided on the top surface of the rear end of the frame 1, an alignment calibration mechanism 6 provided on the top surface of the front end of the frame 1, and a positioning buffer mechanism 7 provided on the rear side of the laser marking mechanism 5.

[0033] The laser marking mechanism 5 includes a base 51. A tilting arm 52 is rotatably connected to the inner side of the base 51. A pressure rod 53 is slidably connected to the top of the tilting arm 52. A connecting rod seat 54 is fixedly connected to the outer surface of the pressure rod 53. A lifting plate 55 is fixedly connected to the bottom end of the connecting rod seat 54. Four vertical sliding rods 58 slide through the surface of the lifting plate 55. A laser lens 56 is installed on the bottom surface of the lifting plate 55. A vertical guide block 57 is slidably connected to the side of the lifting plate 55 away from the tilting arm 52. An air cavity 510 is fixedly connected to the side of the vertical guide block 57 away from the lifting plate 55. A lower pressure cylinder 59 is slidably connected to the top of the air cavity 510. An upper push rod 512 is slidably connected to the inner wall of the lower pressure cylinder 59. A one-way flap 513 is provided above the upper push rod 512. An oil supply pipe 515 is fixedly connected to the wall. An oil discharge pipe 516 is fixedly connected to the top of the lower pressure cylinder 59. An air intake pipe 511 is provided on the outside of the laser lens 56. An air supply pipe 514 is fixedly connected to the top of the air intake pipe 511. A dust collection cone 517 is fixedly connected inside the air intake pipe 511. An elastic cover 518 is fixedly connected to the top of the dust collection cone 517. A blocking plate 519 is provided below the elastic cover 518. An air blowing pipe 520 is fixedly connected to the bottom of the blocking plate 519. The platform 51 is fixedly connected to the platform 3. Four vertical sliding rods 58 are fixedly connected to the platform 3. A vertical guide block 57 is fixedly connected to the platform 3. An oil tank is provided inside the vertical guide block 57. An upper push rod 512 is fixedly connected to the air chamber 510. A one-way flap 513 is connected to the lower pressure cylinder. The inner wall of cylinder 59 is fixedly connected to the oil drain pipe 516, which is interconnected with the interior of cylinder 59. The oil supply pipe 515 is also interconnected with the interior of cylinder 59. The end of the oil supply pipe 515 away from cylinder 59 is connected to the oil tank. A piston is fixedly connected to the bottom of cylinder 59, and the piston is slidably connected to air chamber 510. The suction pipe 511 is fixedly connected to lifting plate 55. The end of the air supply pipe 514 away from suction pipe 511 slides through into air chamber 510 and is fixedly connected to the piston. The baffle plate 519 is fixedly connected to blowing pipe 520. Blowing pipe 520 is unidirectionally connected from the inside of suction pipe 511 to the outside of suction pipe 511. The rotating arm 52 is driven by a motor to rotate around the platform 51, causing the rotating arm 52 to rotate and apply pressure to the pressure rod 53. When downward pressure is applied, the pressure rod 53, under pressure, pushes the connecting rod seat 54 to move. The connecting rod seat 54 causes the lifting plate 55 to move downward along the vertical slide rod 58, bringing the laser lens 56 connected to the bottom side of the lifting plate 55 closer to the part to be marked. During this process, the downward movement of the lifting plate 55 drives the connected lower pressure cylinder 59 to push the bottom piston to slide along the inner wall of the air chamber 510, discharging the air in the air chamber 510 through the air supply pipe 514 connected to the piston. At this time, the air supply pipe 514 moves together with the lower pressure cylinder 59 and slides with the air chamber 510. The air discharged through the air supply pipe 514 is delivered into the connected air intake pipe 511, causing the air to blow the blocking plate 519 downward, creating a gap with the inner wall of the blowing pipe 520, and the air is discharged from the blowing pipe 520 through the gap.The exhaust air blows away dust adhering to the parts being marked, preventing dust from affecting the clarity of the marking. Furthermore, the oil tank built into the vertical guide block 57 discharges oil into the lower pressure cylinder 59 via a connected oil supply pipe 515. As the lower pressure cylinder 59 moves downwards, it approaches the upper push rod 512. The upper push rod 512 compresses the space within the lower pressure cylinder 59, forcing lubricant out through the one-way vane 513. Lubricant is pre-retained above the one-way vane 513 and in the connected oil drain pipe 516. When a certain amount of lubricant accumulates in the oil drain pipe 516, it lubricates the rotating shaft of the tilting arm 52, thereby reducing wear on parts and improving efficiency. To extend the lifespan of components, when the lowering cylinder 59 moves upward, it drives the piston to draw outside air into the air chamber 510. This outside air then draws away dust adhering to the laser lens 56 through the suction pipe 511, allowing the dust to travel with the air through the dust collection cone 517 within the suction pipe 511. The air then pushes open the elastic cover 518 on the dust collection cone 517, allowing air to enter the air chamber 510 through the connected air supply pipe 514. This prevents scratches caused by regular lens wiping and avoids dust buildup on the lens that could damage it, increasing equipment maintenance costs or shortening the lens's lifespan.

[0034] The alignment and calibration mechanism 6 includes a pull-down folding plate 61, an elastic frame 62 is provided below the pull-down folding plate 61, a cross frame 63 is fixedly connected to the front side of the elastic frame 62, an inclined slot plate 64 is fixedly connected to the inner side of the cross frame 63, an upper slot plate 65 is provided to the front side of the inclined slot plate 64, a vertical slide plate 66 is fixedly connected to the front side of the upper slot plate 65, and a bent slide rod 67 is slidably connected between the upper slot plate 65 and the inclined slot plate 64.

[0035] A guide plate 68 is slidably connected to the middle position of the bent slide rod 67. Two hinged connecting rods 69 are hinged to the end of the bent slide rod 67 away from the upper groove plate 65. A pull rod 610 is fixedly connected to the end of each hinged connecting rod 69 away from the bent slide rod 67. A connecting rod cross plate 612 is rotatably connected to the top of each pull rod 610. A fixing strip 611 is slidably connected to one side of the connecting rod cross plate 612. A telescopic push plate 613 is provided on the side of the connecting rod cross plate 612 away from the fixing strip 611. The pull-down folding plate 61 is slidably connected to the platform 3. A tension spring is provided between the pull-down folding plate 61 and the elastic frame 62, and the two ends of the tension spring are respectively connected to the pull-down folding plate 61. The folding plate 61 and the elastic frame 62 are slidably connected. The upper groove plate 65 is slidably connected to the horizontal frame 63. A return spring is provided on the front side of the vertical slide plate 66, and the two ends of the return spring are fixedly connected to the vertical slide plate 66 and the horizontal frame 63 respectively. The guide plate 68 is fixedly connected to the conveyor belt 4. The pull rod 610 is slidably connected to the platform 3. The fixing strip 611 is fixedly connected to the platform 3. A spring plate is provided between the telescopic push plate 613 and the connecting rod horizontal plate 612, and the two ends of the spring plate are fixedly connected to the telescopic push plate 613 and the connecting rod horizontal plate 612 respectively. The telescopic push plate 613 is a telescopic structure composed of a narrow plate and a wide plate. When the tilting arm 52 tilts around the platform 51, the tilting arm... The bottom of 52 applies pressure to the elastic frame 62, causing the elastic frame 62 to pull the downward folding plate 61 downward through the tension spring. The movement of the elastic frame 62 drives the connected horizontal frame 63 and inclined slot plate 64 to move downward. As the inclined slot plate 64 and upper slot plate 65 move downward, they apply pressure to the bending slide rod 67, causing the bending slide rod 67 to pull the connected hinged link 69 along the guide plate 68. During this process, the upper slot plate 65 first slides along the horizontal frame 63 through the connected vertical slide plate 66, compressing the return spring. When the return spring is compressed and contracts, the spring force provides support to the vertical slide plate 66, allowing the vertical slide plate 66 to pull the bending slide rod 69 through the connected upper slot plate 65. The sliding rod 67 slides along the guide plate 68, which pulls the hinged connecting rod 69. The connecting rod 610 connected to the hinged connecting rod 69 pulls the connecting rod cross plate 612 to slide along the fixing bar 611. The fixing bar 611 pushes the telescopic push plate 613 connected to the spring plate, so that the two telescopic push plates 613 move closer to each other and push the accessories on the conveyor belt 4 to the center. When the telescopic push plate 613 contacts the accessories, it squeezes the spring plate to deform, thus preventing the accessories from being deformed by continuous pushing of the telescopic push plate 613. By adjusting the placement of the accessories on the conveyor belt 4, the placement position is prevented from affecting the laser marking position and thus preventing the laser marking effect from being affected.

[0036] The positioning and buffering mechanism 7 includes a pressure plate 71, with two sliding crossbars 72 above the pressure plate 71. A pressure strip 73 is fixedly connected to the top surface of each sliding crossbar 72. A bent connecting rod 74 is fixedly connected to the front end surface of each sliding crossbar 72. A connecting cable 75 is fixedly connected to the rear side of the pressure plate 71. A discharge chute 76 is provided on the rear side of the platform 1. A flip handle 77 is rotatably connected to the side of the discharge chute 76. A buffer flap 78 is fixedly connected to the bottom end of the flip handle 77. The pressure plate 71 is fixedly connected to the pull-down folding plate 61. The bent connecting rod 74... 4. The end of the crossbar 72 away from the chute is fixedly connected to the telescopic push plate 613. The feed chute 76 is fixedly connected to the side plate 2. The end of the connecting cable 75 away from the pressure plate 71 slides through the frame 1 and is fixedly connected to the flip handle 77. The flip arm 52 flips and pushes the elastic frame 62 to pull the tension spring, causing the pull-down folding plate 61 to slide down along the platform 3. The movement of the pull-down folding plate 61 will cause the connected pressure plate 71 to slide down along the vertical slide bar 58. The pressure plate 71, through the connected crossbar 72, causes the pressure strip 73 to slide down together. The telescopic push plate 613... 13. The movement drives the connected bending link 74, causing the bending link 74 to move the sliding crossbar 72 along the horizontal sliding groove on the pressure plate 71. The sliding crossbar 72 moves the connected pressure strip 73 to adapt to the width of the accessory. As the pressure plate 71 falls, the pressure strip 73 moves to apply pressure to the edge of the accessory. At this time, the elastic frame 62 continues to move downward, pulling the tension spring to deform, while the downward bending plate 61 stops moving. The telescopic push plate 613 measures the width of the accessory to assist in adjusting the position of the pressure strip 73. The position adjustment makes the pressure strip 73 more flexible and secure. The pressure strip 73 presses down on the edge of the part to prevent it from obstructing the marking position and to prevent displacement of the part during laser marking. At the same time, when the pressure plate 71 returns to its original position, it pulls the connecting cable 75, causing the connecting cable 75 to rotate the flip handle 77 around the connection point of the feed groove 76. The flip handle 77 then causes the buffer flap 78 to tilt up, which consumes the potential energy generated by the part sliding down the feed groove 76, thus preventing the part from sliding down the feed groove 76 and causing collisions. This buffer flap 78 helps to cushion the part from sliding down and avoid collisions.

[0037] Working principle: The rotating arm 52 is driven by a built-in motor to rotate around the platform 51, causing the rotating arm 52 to rotate and apply downward pressure to the pressure rod 53. The pressure rod 53, under pressure, pushes the connected rod seat 54 to move. The connecting rod seat 54 causes the lifting plate 55 to move downward along the vertical slide rod 58, bringing the laser lens 56 connected to the bottom of the lifting plate 55 closer to the part to be marked. During this process, the downward movement of the lifting plate 55 drives the connected lower pressure cylinder 59 to push the bottom piston to slide along the inner wall of the air chamber 510, expelling the air in the air chamber 510. The air supply pipe 514 connected to the piston discharges air. At this time, the air supply pipe 514 moves together with the pressure cylinder 59 and slides with the air chamber 510. The air discharged through the air supply pipe 514 is delivered into the connected air intake pipe 511, causing the air to blow the blocking plate 519 downward and create a gap with the inner wall of the blowing pipe 520. The air is then discharged from the blowing pipe 520 through the gap. The discharged air blows away the dust attached to the parts being marked, preventing dust from affecting the clarity of the marking. In addition, the oil tank built into the vertical guide block 57 is connected to the oil supply pipe 51. 5. The lubricant is discharged into the lower pressure cylinder 59. As the lower pressure cylinder 59 moves downward, it approaches the upper push rod 512. The upper push rod 512 compresses the space inside the lower pressure cylinder 59, forcing the lubricant out through the one-way vane 513. The lubricant is then pre-retained above the one-way vane 513 and in the connected oil drain pipe 516. When a certain amount of lubricant accumulates in the oil drain pipe 516, it can lubricate the rotating shaft of the tilting arm 52, thereby reducing wear on parts and extending the service life of components. At the same time, when the lower pressure cylinder 59 moves upward, it drives the piston. Outside air is drawn into the air chamber 510. The outside air draws away the dust attached to the laser lens 56 through the suction pipe 511, and the dust is allowed to pass through the dust collection cone 517 in the suction pipe 511 along with the air. The air pushes open the elastic cover 518 on the dust collection cone 517, and allows the air to enter the air chamber 510 through the connected air supply pipe 514. This prevents scratches caused by regular lens wiping and avoids dust adhering to the lens without timely cleaning, which may cause lens damage, increase equipment maintenance costs, or shorten the lens's lifespan.

[0038] When the tilting arm 52 tilts around the platform 51, the bottom end of the tilting arm 52 applies pressure to the elastic frame 62, causing the elastic frame 62 to pull the downward folding plate 61 downward through the tension spring. The movement of the elastic frame 62 drives the connected horizontal frame 63 and inclined slot plate 64 to move downward. As the inclined slot plate 64 and upper slot plate 65 move downward, they apply pressure to the bending slide rod 67, causing the bending slide rod 67 to pull the connected hinged connecting rod 69 along the guide plate 68. During this process, the upper slot plate 65 first slides along the horizontal frame 63 through the connected vertical slide plate 66, compressing the return spring. When the return spring is compressed and contracts, the spring force provides support to the vertical slide plate 66, allowing the vertical slide plate 66 to move downward through the connected vertical slide plate 63. The upper trough plate 65 pulls the bending slide bar 67 to slide along the guide plate 68. The guide plate 68 pulls the hinged connecting rod 69, so that the pull rod 610 connected to the hinged connecting rod 69 pulls the connecting rod cross plate 612 to slide along the fixing bar 611. The fixing bar 611 pushes the telescopic push plate 613 connected to the spring plate, so that the two telescopic push plates 613 move closer to each other and push the accessories on the conveyor belt 4 to the center. When the telescopic push plate 613 contacts the accessories, it squeezes the spring plate to deform, so as to avoid the telescopic push plate 613 continuously pushing the accessories and causing the accessories to be deformed by pressure. By adjusting the placement position of the accessories on the conveyor belt 4, the placement position is avoided from affecting the laser marking position and preventing the laser marking effect from being affected.

[0039] The flipping arm 52 flips and pushes the elastic frame 62, pulling the tension spring and causing the pull-down folding plate 61 to slide downwards along the platform 3. The movement of the pull-down folding plate 61 causes the connected pressure plate 71 to slide downwards along the vertical slide bar 58. The pressure plate 71, through the connected sliding groove bar 72, causes the pressure strip 73 to move downwards together. The movement of the telescopic push plate 613 drives the connected bending connecting rod 74, causing the bending connecting rod 74 to drive the sliding groove bar 72 to slide along the horizontal sliding groove on the pressure plate 71. The sliding groove bar 72 adjusts the movement of the connected pressure strip 73 to adapt to the width of the accessory. As the pressure plate 71 falls, the moving pressure strip 73 applies pressure to the edge of the accessory. At this time, the elastic frame 62 continues to move downwards, pulling the tension spring to deform. The pull-down folding plate 61 stops moving, and the telescopic push plate 613 measures the width of the accessory to assist in adjusting the position of the pressure strip 73. The position adjustment makes the pressure strip 73 press against the edge of the accessory, preventing the pressure strip 73 from blocking the marking position and preventing displacement of the accessory during laser marking. At the same time, when the pressure plate 71 returns to its original position, the pressure plate 71 pulls the connecting cable 75, causing the connecting cable 75 to drive the flip handle 77 to flip around the connection point of the feed groove 76. The flip handle 77 drives the buffer flip plate 78 to tilt up, and the buffer flip plate 78 consumes the potential energy generated by the accessory sliding down the feed groove 76, thereby preventing the accessory from sliding down the feed groove 76 and causing collisions. It can buffer the accessory from sliding down and avoid collisions.
