Description

Technical Field

[0002] The piston pin refers to a component installed on the piston skirt. It is cylindrical in shape. The middle part of the piston pin passes through the small end hole of the connecting rod. It is mainly used to connect the piston and the connecting rod. Its function is to transmit the gas force borne by the piston to the connecting rod, or to make the small end of the connecting rod drive the piston to move together. When producing piston pins, many processes will be involved, including marking the piston pin. After using the marking device to mark the surface of the piston pin, the surface of the piston pin can display information such as the model and production batch number.

[0003] In the prior art, before the piston pin is processed to meet the standards, the processed piston pin needs to be transferred to the standard production line. During the production or transportation process, impurities such as oil or dust are easily adhered to the surface of the piston pin. If the impurities such as oil or dust are not cleaned in time, when the piston pin is marked, oil and dust will cover the surface of the piston pin, blocking the direct action area of ​​the laser beam, resulting in the laser energy being unable to fully act on the material surface, thereby affecting the marking effect.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1 Reference Figure 1-Figure 13A piston pin marking production line includes a processing table 1, a horizontal plate 2 is fixedly connected to the top of the processing table 1, a threaded rod 3 is threadedly connected to one side of the horizontal plate 2, a clamping plate 4 is rotatably connected to one side of the threaded rod 3, a conveyor belt 5 is arranged on the top of the processing table 1, and the clamping plate 4 is arranged on the top of the conveyor belt 5, a side plate 6 is fixedly connected to the side of the top of the processing table 1 away from the horizontal plate 2, a vertical rod 7 is fixedly connected to the top of the processing table 1, a laser marking head 8 is slidably connected to one side of the vertical rod 7, a control console 9 is fixedly connected to the top of the processing table 1, and also includes a cleaning component for cleaning the surface of the piston pin, the cleaning component is arranged on the top of the processing table 1, and the cleaning The component includes a mounting plate 10, which is fixedly connected to the top of the processing table 1, a first cover plate 19 is fixedly connected to one side of the mounting plate 10, a storage tank 29 is fixedly connected to the top of the first cover plate 19, cleaning liquid is stored in the storage tank 29, a control component for controlling the addition of cleaning liquid is arranged at the top of the first cover plate 19, a uniform component for applying the cleaning liquid is arranged at the bottom of the first cover plate 19, a stirring component for preventing the cleaning liquid from settling is arranged inside the storage tank 29, a fixing component for fixing a piston pin is arranged at the bottom of the processing table 1, and a purification component for treating exhaust gas is arranged on one side of the processing table 1.

[0032] In order to solve the problem that oil or dust on the surface of the piston pin will affect the marking on the surface of the piston pin, when the piston pin needs to be marked, the position of the clamping plate 4 can be adjusted to one side by rotating the multiple sets of threaded rods 3. When the clamping plate 4 moves to one side, the distance between the clamping plate 4 and the side plate 6 can be adjusted to adapt to piston pins of different sizes. Then, the piston pins are arranged and placed on the conveyor belt 5, and the piston pins are conveyed to one side by the conveyor belt 5. The cleaning component provided on the mounting plate 10 can be started. By starting the cleaning component, the top of the piston pin can be cleaned to prevent oil or dust from existing on the top of the piston pin. When the cleaning component is running, it will drive the control component to run. Thereby, the cleaning liquid in the storage tank 29 can be controlled to be added intermittently downward, and the specified amount of cleaning liquid can be helpful in wiping off impurities such as oil stains. By setting a uniform component, the cleaning liquid can be evenly distributed. By setting a stirring component, when the control component is running, the stirring component can be driven to turn over the cleaning liquid in the storage tank 29 to prevent precipitation in the cleaning liquid and promote uniform mixing of the cleaning liquid. By setting a fixing component at the bottom of the processing table 1, the piston pin can be intermittently fixed to the bottom of the laser marking machine during the piston pin marking operation, which is beneficial to the marking operation. By setting a purification component, the exhaust gas generated by the laser marking can be treated when the piston pin is marked.

[0033] Reference Figure 3-Figure 4The cleaning assembly also includes a first motor 11, a first rotating rod 12 is fixedly connected to the output end of the first motor 11, a first cleaning pad 13 is fixedly connected to the bottom of the first rotating rod 12, the first rotating rod 12 is rotatably connected to the inner wall of the first cover plate 19, a first pulley 14 is fixedly connected to the outer wall of the first rotating rod 12, a transmission belt 15 is sleeved on the outer wall of the first pulley 14, a second pulley 16 is sleeved on the other side of the inner wall of the transmission belt 15, a second rotating rod 17 is fixedly connected to the center of the second pulley 16, the second rotating rod 17 is rotatably connected to the bottom of one side of the mounting plate 10, a second cleaning pad 18 is fixedly connected to the bottom of the second rotating rod 17, a second cover plate 20 is fixedly connected to one side of the mounting plate 10, and the second cover plate 20 is arranged on the top of the second cleaning pad 18.

[0034] When it is necessary to clean the top of the piston pin, the first motor 11 can be started, so that the first motor 11 drives the first rotating rod 12 arranged at the output end to rotate. When the first rotating rod 12 rotates, the first cleaning pad 13 arranged at the bottom will be driven to rotate. Since the cleaning liquid in the storage tank 29 will flow downward to the first cleaning pad 13, the first cleaning pad 13 soaked with the cleaning liquid can fully wipe the dust and impurities on the surface of the piston pin when rotating. When the first rotating rod 12 rotates, it will drive the first pulley 14 arranged on its outer wall to rotate. When the first pulley 14 rotates, it will drive the transmission belt 15 of the outer wall to rotate, and the transmission belt 15 will drive the second pulley 16 to rotate. When the second pulley 16 rotates, it will drive the second rotating rod 17 arranged at the center to rotate, and the second cleaning pad 18 arranged at the bottom of the second rotating rod 17 will also rotate accordingly. Since the second cleaning pad 18 does not contain cleaning liquid, the second cleaning pad 18 can wipe the cleaning liquid remaining on the top of the piston pin when rotating, and the top of the piston pin can be cleaned, which is beneficial to marking the piston pin.

[0035] Reference Figure 5-Figure 6 The control assembly includes a vertical rod 21, which is fixed to the top of the first cover plate 19, and a slide groove is provided on one side of the vertical rod 21. A slider 22 is slidably connected to the inner wall of the slide groove, and a round sleeve 23 is fixed to one side of the slider 22. The round sleeve 23 is sleeved on the outer wall of the first rotating rod 12, and a guide groove 24 is provided on the inner wall of the round sleeve 23. The guide groove 24 is in an arc shape, and a circular protrusion 25 is fixed to the outer wall of the first rotating rod 12, and the circular protrusion 25 is slidably connected to the inner wall of the guide groove 24. A connecting plate 26 is fixed to one side of the round sleeve 23, and a control rod 27 is fixed to the bottom of the connecting plate 26. The control rod 27 is slidably connected to the inner wall of the storage tank 29, and a plug 28 is fixed to the bottom of the control rod 27. An injection hole is provided on the top of the first cover plate 19, and the injection hole is connected to the inner wall of the storage tank 29, and the plug 28 is plugged into the bottom of the inner wall of the storage tank 29.

[0036] When the first rotating rod 12 rotates, the circular protrusion 25 on its outer wall will be driven to rotate together. Since the circular protrusion 25 is rotatably connected to the inner wall of the guide groove 24, and the shape of the guide groove 24 is arc-shaped, the circular protrusion 25 can drive the circular sleeve 23 to move back and forth up and down. When the circular sleeve 23 moves back and forth up and down, the slider 22 on one side will be driven to slide. The slider 22 slides in the slide groove on one side of the vertical rod 21, which can limit the trajectory of the circular sleeve 23 moving up and down. When the circular sleeve 23 moves back and forth up and down, it will drive the connecting plate 26 and the control rod 27 set on one side to move back and forth together. 27 is slidably connected in the storage tank 29, so when the control rod 27 moves upward, it will drive the plug 28 to move upward from the bottom of the inner wall of the storage tank 29, so that the cleaning liquid in the storage tank 29 can flow into the injection hole and flow downward into the first cleaning pad 13 through the injection hole, so that the first cleaning pad 13 is soaked with the cleaning liquid, and then the sliding sleeve will drive the connecting plate 26 and the control rod 27 to move downward, so that the plug 28 at the bottom of the control rod 27 moves downward to the bottom of the inner wall of the storage tank 29, thereby closing the bottom of the storage tank 29, blocking the cleaning liquid in the storage tank 29 from flowing downward, and preventing excessive addition of cleaning liquid.

[0037] Reference Figure 7 The uniform component includes a cylinder 31, which is rotatably connected to the bottom of the first cover plate 19. A mounting groove 30 is provided at the bottom of the first cover plate 19. The mounting groove 30 is arranged at the bottom of the injection hole. The cylinder 31 is arranged inside the mounting groove 30. The outer wall of the cylinder 31 is fixedly connected with spiral bars 32. The spiral bars 32 are provided in two groups and are symmetrically distributed on the outer wall of the cylinder 31. The bottom of the cylinder 31 is attached to the top of the first cleaning pad 13.

[0038] After the cleaning liquid flows downward into the injection hole, it will flow along the injection hole into between the first cover plate 19 and the first cleaning pad 13, so that the first cleaning pad 13 is gradually soaked. By arranging a rotating cylinder 31 in the mounting groove 30, when the first cleaning pad 13 rotates, the two groups of spiral bars 32 arranged on the outer wall of the cylinder 31 can be driven to rotate by friction, and the two groups of spiral bars 32 will drive the cylinder 31 to rotate together when rotating. Since the cylinder 31 and the spiral bars 32 are arranged at the bottom of the injection hole, when the cleaning liquid flows to the rotating cylinder 31 and the top of the spiral bars 32, the two groups of spiral bars 32 can be used to guide the cleaning liquid to both sides of the cylinder 31, which is conducive to evenly laying the cleaning liquid on the top of the first cleaning pad 13 and preventing the cleaning liquid from accumulating in one place.

[0039] Reference Figure 8-Figure 11The stirring assembly includes a pressure rod 33, which is fixedly connected to the outer wall of the control rod 27. A support ring 34 is fixedly connected to the inner wall of the storage tank 29. A first spring 35 is fixedly connected to the top of the support ring 34. A push ring 36 is fixedly connected to the top of the first spring 35. The pressure rod 33 is arranged at the top of the push ring 36. A vertical bar 44 is fixedly connected to the inner wall of the storage tank 29. A square groove is provided on the outer wall of the push ring 36. The push ring 36 is slidably connected to the outer wall of the vertical bar 44 through the square groove. A rack 37 is fixedly connected to the inner wall of the storage tank 29. The rack 37 is L-shaped, and a fixing frame 38 is fixedly connected to the inner wall of the push ring 36. A short rod is rotatably connected to one side of the fixing frame 38. A first gear 40 is fixedly connected to one side of the short rod. The first gear 40 is meshed with one side of the rack 37. A first bevel gear 39 is fixedly connected to the other end of the short rod. A second bevel gear 41 is meshed with one side of the first bevel gear 39. A round rod 42 is fixedly connected to the bottom of the second bevel gear 41. The round rod 42 is rotatably connected to the bottom of the fixing frame 38, and a stirring plate 43 is fixedly connected to the bottom of the round rod 42.

[0040] When the control rod 27 moves downward, it will drive the pressure rod 33 set on the outer wall to move downward together, and when the pressure rod 33 moves downward, it will push the push ring 36 to move downward together, and at the same time squeeze the first spring 35 at the bottom. When the push ring 36 moves downward, it will drive the fixed frame 38, the short rod, the first gear 40, the first bevel gear 39, the second bevel gear 41, the round rod 42 and the stirring plate 43 on one side to move downward together. When the push ring 36 moves downward, it can slide on the vertical bar 44 through the square groove on the outer wall of the push ring 36, thereby limiting the movement trajectory of the push ring 36. When the first gear 40 moves downward on one side of the rack 37, the first gear 40 will rotate. When the first gear 40 rotates, it will drive the short rod and the first bevel gear 39 on one side to rotate, and the first bevel gear 39 will drive the second bevel gear 41 meshed at the bottom to rotate together. When the second bevel gear 41 rotates, it will drive the round rod 42 and the stirring plate 43 at the bottom to rotate together. When the control rod 27 moves upward, the pressure rod 33 is also driven to move upward. When the pressure rod 33 moves upward, the first spring 35 loses its extrusion force and is reset upward. When the first spring 35 is reset, the push ring 36 is also pushed to reset upward. When the push ring 36 is reset, the fixing frame 38, the short rod, the first gear 40, the first bevel gear 39, the second bevel gear 41, the round rod 42 and the stirring plate 43 are driven to move upward together. When the first gear 40 moves upward on one side of the rack 37, the first gear 40 is caused to rotate in the opposite direction. When the first gear 40 rotates in the opposite direction, the stirring plate 43 is driven to rotate in the opposite direction through the short rod, the first bevel gear 39, the second bevel gear 41 and the round rod 42, thereby further promoting the mixing of the cleaning liquid.

[0041] Reference Fig.12 The fixing assembly includes an L-shaped plate 45, which is fixedly connected to the bottom of the processing table 1, and a second motor 46 is fixedly connected to the top of one side of the L-shaped plate 45, and an output shaft 47 is fixedly connected to the output end of the second motor 46, and a circular plate 48 is fixedly connected to the top of the output shaft 47, and an arc plate 49 is fixedly connected to one side of the circular plate 48, and a baffle 50 is fixedly connected to one side of the bottom of the processing table 1, and a second spring 51 is fixedly connected to one side of the baffle 50, and a push rod 52 is fixedly connected to one side of the second spring 51, and the shape of the push rod 52 is L-shaped, and the push rod 52 is slidably connected to the top of the processing table 1, and a clamping block 53 is fixedly connected to one side of the top of the push rod 52, and the clamping block 53 is arranged at the top of the clamping plate 4, and a pad is fixedly connected to one side of the side plate 6.

[0042] When the piston pin needs to be marked, the second motor 46 can be started and the speed of the second motor 46 can be adjusted. The output shaft 47 and the circular plate 48 are driven to rotate by the second motor 46. The arc plate 49 provided on one side of the circular plate 48 will also rotate with the circular plate 48. When the arc plate 49 rotates to one side of the push rod 52, the push rod 52 will be pushed to one side. When the push rod 52 moves to one side, it will squeeze the second spring 51 and drive the clamping block 53 to move to one side. When a group of piston pins moves to the bottom of the laser marking head 8, the arc plate 49 will move from one side of the push rod 52 to the other side. When the piston pin is moved to the side, the second spring 51 loses its thrust and returns to one side, and pushes the push rod 52 and the clamp block 53 to return to the same position, so that the clamp block 53 cooperates with the side plate 6 to clamp the piston pin, thereby fixing the position of the piston pin at the bottom of the laser marking head 8, and the top of the piston pin is marked by the laser marking head 8. After the marking is completed, the arc plate 49 on one side of the circular plate 48 will rotate to the side of the push rod 52 again, and push the push rod 52 and the clamp block 53 to one side again, thereby releasing the fixation of the piston pin, and the piston pin after marking is conveyed to one side by the conveyor belt 5.

[0043] Reference Fig.13 The purification component includes a second gear 54, which is fixed to the outer wall of the output shaft 47 and arranged at the bottom of the circular plate 48. A toothed belt 55 is meshed on the outer wall of the second gear 54, and a third gear 57 is meshed on the other side of the inner wall of the toothed belt 55. The size of the third gear 57 is smaller than the second gear 54. A bracket 56 is fixed to one side of the L-shaped plate 45, and the toothed belt 55 and the second gear 54 are arranged at the top of the bracket 56. A long rod 58 is fixed to the top of the second gear 54, and a fan blade 59 is fixed to the outer wall of the long rod 58. A wind tube 60 is fixed to one side of the processing table 1, and the fan blade 59 is arranged inside the wind tube 60. A filter layer 61 is fixed to the inner wall of the wind tube 60, and the opening of the wind tube 60 is arranged on one side of the laser marking head 8.

[0044] When the output shaft 47 rotates, it will drive the second gear 54 provided on the outer wall to rotate together. When the second gear 54 rotates, it will drive the toothed belt 55 sleeved on its outer wall to rotate. When the toothed belt 55 rotates, it will drive the third gear 57 to rotate. By setting the bracket 56, the positions of the toothed belt 55, the second gear 54 and the third gear 57 can be limited. Since the size of the third gear 57 is smaller than the second gear 54, the rotation speed of the third gear 57 is greater than the rotation speed of the second gear 54. When the third gear 57 rotates, it will drive the long rod 58 and the fan blades 59 at the top to rotate together. When the fan blades 59 rotate, suction will be generated in the wind tube 60, which can suck the exhaust gas generated by the laser marking head 8 into the wind tube 60, and filter the exhaust gas through the filter layer 61 in the wind tube 60, so as to prevent the exhaust gas generated by the laser marking from causing damage to the bodies of the surrounding staff.

[0045] Reference Figure 1 A conveying box 62 is fixedly connected to one side of the processing table 1 away from the mounting plate 10 , and an inclined surface is arranged inside the conveying box 62 . One side of the inclined surface is rotatably connected to multiple groups of rollers, and a collecting box 63 is arranged on one side of the conveying box 62 .

[0046] By setting a conveying box 62 on one side of the processing table 1, the piston after marking can be conveyed into the conveying box 62. By setting a roller on the inclined surface of the conveying box 62, the piston pin can be conveyed downward along the inclined surface until the processed piston pin is passed into the collection box 63.

[0047] Working principle: In order to solve the problem that oil or dust on the surface of the piston pin will affect the marking of the piston pin surface, when the piston pin needs to be marked, the position of the clamping plate 4 can be adjusted to one side by rotating the multiple sets of threaded rods 3. When the clamping plate 4 moves to one side, the distance between the clamping plate 4 and the side plate 6 can be adjusted to adapt to piston pins of different sizes. Then, the piston pins are arranged and placed on the conveyor belt 5, and the piston pins are conveyed to one side by the conveyor belt 5. When the top of the piston pin needs to be cleaned, the first motor 11 can be started to drive the first rotating rod 12 and the first cleaning pad 13 to rotate. When the first rotating rod 12 rotates, the first motor 11 can be started to drive the first rotating rod 12 and the first cleaning pad 13 to rotate. When the circular sleeve 23 reciprocates up and down, the slider 22 on one side will be driven to slide, and the slider 22 slides in the slide groove on one side of the vertical rod 21, which can limit the trajectory of the circular sleeve 23 moving up and down. When the circular sleeve 23 reciprocates up and down, the connecting plate 26 and the control rod 27 set on one side will be driven to reciprocate together. Since the control rod 27 is slidably connected in the storage tank 29, the control rod 27 can be slidably connected to the storage tank 29. When the rod 27 moves upward, it will drive the plug 28 to move upward from the bottom of the inner wall of the storage tank 29, so that the cleaning liquid in the storage tank 29 can flow into the injection hole and flow downward through the injection hole into the first cleaning pad 13, so that the first cleaning pad 13 is gradually soaked. By arranging a rotating cylinder 31 in the mounting groove 30, when the first cleaning pad 13 rotates, the two groups of spiral strips 32 arranged on the outer wall of the cylinder 31 can be driven to rotate by friction, and the two groups of spiral strips 32 will drive the cylinder 31 to rotate together when rotating. Since the cylinder 31 and the spiral strips 32 are arranged at the bottom of the injection hole, when the cleaning liquid flows to the rotating cylinder 3 1 and the top of the spiral strips 32, the cleaning liquid can be guided to the two sides of the cylinder 31 by the two sets of spiral strips 32, so that the cleaning liquid is evenly laid on the top of the first cleaning pad 13 to prevent the cleaning liquid from accumulating in one place. The first cleaning pad 13 soaked with the cleaning liquid can fully wipe the dust and impurities on the surface of the piston pin when rotating, and then the sliding sleeve will drive the connecting plate 26 and the control rod 27 to move downward, so that the plug 28 at the bottom of the control rod 27 moves downward to the bottom of the inner wall of the storage tank 29, and the bottom of the storage tank 29 can be closed to block the cleaning liquid in the storage tank 29 from flowing downward, so as to prevent excessive addition of cleaning liquid; When the control rod 27 moves downward, it will drive the pressure rod 33 set on the outer wall to move downward together, and when the pressure rod 33 moves downward, it will push the push ring 36 to move downward together, and at the same time squeeze the first spring 35 at the bottom. When the push ring 36 moves downward, it will drive the fixing frame 38, the short rod, the first gear 40, the first bevel gear 39, the second bevel gear 41, the round rod 42 and the stirring plate 43 on one side to move downward together. When the push ring 36 moves downward, it can slide on the vertical bar 44 through the square groove on the outer wall of the push ring 36, thereby limiting the movement trajectory of the push ring 36. When the first gear 40 moves downward on one side of the rack 37, the first gear 4 0 generates rotation, and when the first gear 40 rotates, it will drive the short rod on one side and the first bevel gear 39 to rotate, and the first bevel gear 39 will drive the second bevel gear 41 meshed at the bottom to rotate together. When the second bevel gear 41 rotates, it will drive the round rod 42 and the stirring plate 43 at the bottom to rotate together. When the stirring plate 43 rotates, it will produce a stirring effect on the cleaning liquid. The stirring plate 43 will move downward while rotating, thereby increasing the stirring range. When the cleaning liquid is stirred, precipitation can be prevented in the cleaning liquid, and the cleaning liquid can be mixed evenly. When the control rod 27 moves upward, it will also drive the pressure rod 33 to move upward together. When the first spring 35 is reset, the push ring 36 is also pushed to reset upward. When the push ring 36 is reset, the fixing frame 38, the short rod, the first gear 40, the first bevel gear 39, the second bevel gear 41, the round rod 42 and the stirring plate 43 are driven to move upward together. When the first gear 40 moves upward on one side of the rack 37, the first gear 40 is caused to rotate in the opposite direction. When the first gear 40 rotates in the opposite direction, the stirring plate 43 is driven to rotate in the opposite direction through the short rod, the first bevel gear 39, the second bevel gear 41 and the round rod 42, thereby further promoting the uniform mixing of the cleaning liquid. When the rotating rod 12 rotates, it will drive the first pulley 14 arranged on its outer wall to rotate. When the first pulley 14 rotates, it will drive the transmission belt 15 on the outer wall to rotate. The transmission belt 15 will drive the second pulley 16 to rotate. When the second pulley 16 rotates, it will drive the second rotating rod 17 arranged at the center to rotate. The second cleaning pad 18 arranged at the bottom of the second rotating rod 17 will also rotate accordingly. Since the second cleaning pad 18 does not contain cleaning liquid, the second cleaning pad 18 can wipe off the cleaning liquid remaining on the top of the piston pin when it rotates, so that the top of the piston pin can be cleaned, which is conducive to marking the piston pin; When it is necessary to mark the cleaned piston pin, the second motor 46 can be started, and the speed of the second motor 46 can be adjusted. The output shaft 47 and the circular plate 48 are driven to rotate by the second motor 46, and the arc plate 49 set on one side of the circular plate 48 will also rotate with the circular plate 48. When the arc plate 49 rotates to one side of the push rod 52, the push rod 52 will be pushed to one side. When the push rod 52 moves to one side, it will squeeze the second spring 51 and drive the clamping block 53 to move to one side. When a group of piston pins moves to the bottom of the laser marking head 8, When the piston pin is in the state of being pressed down, the arc plate 49 will move away from one side of the push rod 52, so that the second spring 51 will be reset to one side after losing the thrust, and push the push rod 52 and the clamping block 53 to be reset together, so that the clamping block 53 cooperates with the side plate 6 to clamp the piston pin, thereby fixing the position of the piston pin at the bottom of the laser marking head 8, and marking the top end of the piston pin by the laser marking head 8. After the marking is completed, the arc plate 49 on one side of the circular plate 48 will rotate to one side of the push rod 52 again, and push the push rod 52 and the clamping block 53 to one side again, thereby releasing the piston pin. The piston pin is fixed, and the piston pin after marking is transmitted to one side to the transmission box 62 through the conveyor belt 5, so that the piston pin after processing is transmitted to the collection box 63 through the transmission box 62. When the output shaft 47 rotates, the second gear 54 set on the outer wall will be driven to rotate together. When the second gear 54 rotates, it will drive the toothed belt 55 set on its outer wall to rotate. When the toothed belt 55 rotates, it will drive the third gear 57 to rotate. By setting the bracket 56, the toothed belt 55, the second gear 54 and the third gear can be connected to each other. The position of the third gear 57 is limited. Since the size of the third gear 57 is smaller than that of the second gear 54, the rotation speed of the third gear 57 is greater than that of the second gear 54. When the third gear 57 rotates, the long rod 58 and the fan blades 59 at the top are driven to rotate together. When the fan blades 59 rotate, suction is generated in the air duct 60, and the exhaust gas generated by the laser marking head 8 is sucked into the air duct 60, and the exhaust gas is filtered through the filter layer 61 in the air duct 60, so as to prevent the exhaust gas generated by the laser marking from causing damage to the bodies of the surrounding staff.
