Technical Field

[0001] The present invention relates to the technical field of laser marking, in particular to a laser marking device for tire production. Background Art

[0002] Tires are circular elastic rubber products that roll against the ground and are installed on various vehicles or machinery. A common use of tires is to be installed on metal rims to support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the vehicle's driving performance.

[0003] Patent publication number CN214350291U discloses a laser marking device for tire production, comprising a base with a connecting column sleeved on the base, a plurality of fixed columns uniformly welded to the outside of the connecting column, a baffle at the other end of the fixed column, a bottom plate welded to the bottom of the baffle, a telescopic push rod and a push plate mounted inside the fixed column, a lifting column, a telescopic column, and a top plate mounted inside the bottom plate, a support column welded to the top of the connecting column, a fixed ring welded to the top of the support column, a mounting column mounted on the fixed ring, and a laser emitter mounted on the mounting column. The patent discloses a laser marking device for tire production, belonging to the field of automotive parts production. The device utilizes a base and connecting column connected by bearings, a motor and transmission gear transmission, and fixed columns with telescopic push rods and push plates uniformly welded to the outside of the connecting column. Corresponding laser emitters are provided, allowing it to be connected to a production line to achieve assembly line production, improve efficiency, and increase production capacity, while reducing manpower and material input and lowering costs.

[0004] However, the device still has shortcomings: the device can laser mark tires and realize assembly line production, but it is difficult to ensure that the tire and the laser emitter are always in the same orientation during the marking process, and it is difficult for the tire to ensure that it is located in the center of the transmission assembly during transportation to facilitate laser marking, which can easily lead to misalignment or ambiguity of the marking. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a tire production laser marking device, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a tire production laser marking device, comprising a base, support columns are provided at the top corners of the base, a transmission assembly is provided on the top of the support columns, a transmission roller is provided inside the transmission assembly, a vertical column is provided at the top edge of the transmission assembly, a top plate is provided on the top of the vertical column, an electric slide is provided at the center of the bottom of the top plate, an electric telescopic rod is slidably installed inside the electric slide, a laser assembly is fixedly installed at the bottom of the telescopic end of the electric telescopic rod, an intelligent module is provided on the top of the laser assembly, two water-cooling assemblies are fixedly installed at the bottom of the top plate, and the two water-cooling assemblies are connected to the electric slide The L-shaped baffle is fixedly installed on one side of the outer wall of the laser assembly, and an elastic telescopic plate is fixedly installed on the top of the transmission assembly. A telescopic limit plate is hinged on the side of the elastic telescopic plate away from the L-shaped baffle 11. A central friction column is rotatably installed inside the groove of the telescopic end of the telescopic limit plate. The transmission assembly is started, and the transmission assembly drives the transmission roller through the internal motor. The transmission roller drives the tire on its top that needs to be laser marked to move toward the direction close to the laser assembly. Before the tire is conveyed, the electric telescopic rod is started, and the telescopic end of the electric telescopic rod drives the laser assembly downward. The laser The component drives the L-shaped baffle to descend synchronously, and at the same time starts the exhaust component, which sucks and absorbs the dust raised around the laser component through the air outlet on the right side of the L-shaped baffle. When the laser marking work starts, the exhaust component stops working to avoid interfering with the laser component. At the same time, when the tire is transported to the designated marking location, it is resisted by the L-shaped baffle. At this time, the intelligent module controls the transmission component to stop transporting the tire, and starts the laser component to mark the tire information. The electric slide rail is started, and the electric slide rail drives the electric telescopic rod to slide back and forth inside itself. The electric telescopic rod drives the laser component to move synchronously. At the same time, when the laser component moves downward, it pulls the spiral conveying pipe to move synchronously. During the interruption process, the water cooling component cools down the laser component through the spiral conveying pipe; when the L-shaped baffle moves downward, the telescopic end of the elastic telescopic plate is pressed to move synchronously, and the telescopic limit plate on one side of the elastic telescopic plate remains stationary. At the same time, during the tire transportation process, the outer wall of the tire contacts the outer wall of the central friction column to generate friction, and the central friction column starts to rotate due to the friction force. At this time, when the tire is in a non-center position of the drive roller, it will resist the central friction column. The central friction column resists the telescopic end of the telescopic limit plate through the resistance force to generate a contraction force. The telescopic end of the telescopic limit plate is reset by the rebound force of the built-in spring and pushes the central friction column to reset. At this time, the central friction column pushes the tire to move toward the center of the drive roller.

[0007] According to the above technical solution, an exhaust assembly is provided on the left side of the outer wall of the L-shaped baffle, and an air outlet is provided on the right side of the L-shaped baffle. The top of the telescopic end of the elastic telescopic plate contacts the bottom of the L-shaped baffle, a torsion spring is provided between the fixed end of the telescopic limit plate and the fixed end of the elastic telescopic plate, a groove is provided at the telescopic end of the telescopic limit plate, and an anti-sway device is provided on the inner side of the elastic telescopic plate to ensure good stability of the tire during laser marking.

[0008] According to the above technical solution, the anti-sway device includes a transmission plate, a fixed rod, several vibration plates, a telescopic bottom plate and an arc block. The top of the transmission plate is hinged to the side of the telescopic end of the elastic telescopic plate close to the center of the top plate through a torsion spring. The end of the fixed rod away from the center of the top plate is fixedly installed on the outer wall of the fixed end of the elastic telescopic plate. Several of the vibration plates pass through and are fixedly installed on the outer wall of the fixed rod. The top of the fixed end of the telescopic bottom plate is hinged to the bottom of the transmission plate. The bottom of the telescopic bottom plate contacts the top of the transmission assembly. The bottom of the arc block is fixedly installed on the top of the fixed end of the telescopic bottom plate. The bottom of the vibration plate is located on the arc surface motion track of the arc block. On the trace, when the telescopic end of the elastic telescopic plate is pressed by the L-shaped baffle and moves downward, it drives the transmission plate to move synchronously. The transmission plate is restricted by the telescopic bottom plate, causing the hinge shaft between itself and the elastic telescopic plate to start rotating. At this time, the bottom of the transmission plate pushes the telescopic bottom plate to slide along the top of the transmission assembly toward the center of the top plate. The telescopic bottom plate drives the arc block to move synchronously. During the movement, the arc block's own arc surface contacts the arc surface at the bottom of the vibration plate. The vibration plate is limited by the fixed rod to ensure that it is stationary, but the bottom of the vibration plate begins to bend and deform due to the interference of the arc block. When the arc block passes over the vibration plate and is reset by its own toughness, it will swing back and forth to generate vibration.

[0009] The U-shaped plate is fixed on the U-shaped plate by a spring and is slidably mounted on the U-shaped plate. At the same time, the L-shaped penetration plate drives the elastic arc sheet to move downward when it contacts the edge of the tire outer wall, causing deformation and always clinging to the irregular tooth marks on the tire edge.

[0010] According to the above technical solution, the friction plate is located on the movement trajectory of the outer wall of the rotating wheel close to the telescopic bottom plate. A spiral groove is provided above the outer wall of the rotating rod. The outer wall of the limiting column is movable through the interior of the U-shaped plate. A U-shaped groove is provided inside the telescopic end of the L-shaped penetration plate. An anti-pollution device is provided on the top of the U-shaped plate to prevent dirt from interfering with the laser marking process.

[0011] According to the above technical solution, the anti-pollution device includes a hollow mesh plate, a sliding intercepting plate, a hinged rod, a resistance plate and an arc plate. The bottom of the hollow mesh plate is fixedly installed on the top of the U-shaped plate. The outer wall of the sliding intercepting plate passes through and is slidably installed inside the hollow mesh plate. A square groove is opened under the sliding intercepting plate. The bottom of the hinged rod is hinged at the top edge of the L-shaped through-plate. The top of the hinged rod is hinged at the outer wall of the sliding intercepting plate. The bottom of the resistance plate is fixedly installed on the top of the sliding intercepting plate. The bottom of the arc plate is hinged at the outer wall of the hollow mesh plate through a torsion spring. The top of the inner wall of the arc plate is located at the resistance plate. On the motion trajectory, when the U-shaped plate moves toward the center of the top plate, it drives the hollow mesh plate to move synchronously, and the hollow mesh plate drives the sliding intercepting plate to move synchronously. At this time, the hinged rod is pushed and limited by the L-shaped through-plate, causing its own hinge axis to start rotating. At this time, the hinged rod rotates through the hinge axis to push the sliding intercepting plate to slide upward along the inner wall of the hollow mesh plate. When the sliding intercepting plate moves upward, it drives the contact plate to move synchronously. When the contact plate moves upward, it resists the arc surface of the arc plate, causing the hinge axis between the arc plate and the hollow mesh plate to start rotating, causing the arc plate to rotate in an arc shape with the hinge axis as the axis center in the direction away from the outer wall of the hollow mesh plate.

[0012] According to the above technical solution, the anti-pollution device also includes a circular wheel, a cross bar, a sliding plate and a limit rod. The circular wheel is rotatably installed on the outer wall of the sliding intercepting plate near the center of the hollow mesh plate, and both ends of the cross bar are fixedly installed at the center of the inner wall of the circular wheel. The sliding plate passes through and is fixedly installed on the outer wall of the cross bar. Both ends of the limit rod are fixedly installed on the inner wall of the sliding intercepting plate. When the sliding intercepting plate moves upward, it drives the circular wheel to move synchronously. When the circular wheel contacts the inner wall of the hollow mesh plate, friction is generated and it starts to rotate. The circular wheel drives the cross bar to rotate. When the cross bar rotates, it limits the sliding plate through the reciprocating spiral groove on its own outer wall, and the built-in block of the sliding plate continuously contacts the inner wall of the reciprocating spiral groove. At the same time, the sliding plate is limited by the limit rod, which enables the sliding plate to slide horizontally along the outer wall of the reciprocating spiral groove of the cross bar.

[0013] According to the above technical solution, the outer wall of the circular wheel contacts the inner wall of the hollow mesh plate, the outer wall of the cross bar is provided with a number of reciprocating spiral grooves at equal intervals, the interior of the sliding plate contacts the reciprocating spiral grooves on the outer wall of the cross bar, the side of the sliding plate close to the sliding intercepting plate contacts the inner wall of the hollow mesh plate, and the outer wall of the limit rod moves through the interior of the sliding plate.

[0014] The present invention provides a tire production laser marking device. It has the following beneficial effects:

[0015] (1) The present invention cooperates with an electric slide rail, an electric telescopic rod, a laser assembly, a water-cooling assembly, a spiral conveying pipe, an L-shaped baffle, an elastic telescopic plate, a telescopic limit plate and a central friction column. The L-shaped baffle is used to block the tire and the laser assembly to ensure that the tire is always in the same orientation for marking, which simplifies the orientation adjustment during the laser marking process of the tire and reduces manual participation, thereby avoiding the marked data information from constantly changing orientation after the tire is laser marked, which affects the inspection experience of the inspectors at the same perspective, and at the same time ensures that the laser assembly operates at a low temperature for a long time to reduce the loss of use; at the same time, the tire that deviates from the center orientation of the transmission roller is conveyed in the center by the limited rotation of the central friction columns on both sides and the limited resistance of the telescopic limit plate, thereby preventing the tire and the laser assembly from being in the preset orientation for data marking during the tire marking process, and avoiding the phenomenon of misalignment or ambiguity in the data marking of the tire by the laser assembly.

[0016] (2) The present invention adopts the setting of an anti-sway device, and cooperates with an elastic telescopic plate, a transmission plate, a fixed rod, a vibration plate, a telescopic bottom plate, an arc block, a rotating wheel, a friction plate, a rotating rod, a U-shaped plate, a limiting column, an L-shaped through-plate, a guide plate and an elastic arc sheet. The vibration force of the vibration plate is used to reduce the friction blockage phenomenon when the central friction column contacts the outer wall of the tire, and prevent the central friction column from being difficult to rotate due to excessive friction or tire orientation deviation, thereby reducing the conveying passability of the tire and reducing the laser marking efficiency; at the same time, the U-shaped plate is prompted to clamp the outer wall of the tire stably, and the clamping range of the tire is expanded with the help of the L-shaped through-plate and the elastic arc sheet, thereby improving the clamping and limiting stability of the tire on the original basis, avoiding the shaking of the tire due to equipment vibration or external force interference, thereby preventing the laser marked data from being dislocated and broken, and ensuring the integrity of the laser marking.

[0017] (3) The present invention adopts the setting of anti-pollution device, and cooperates with U-shaped plate, hollow mesh plate, sliding intercepting plate, hinged rod, resistance plate, arc plate, round wheel, cross bar, sliding plate and limiting rod, and relies on sliding intercepting plate to expand the interception range of dust brought by hollow mesh plate during laser marking of tire by laser assembly, and at the same time, overflowing dust is shielded by arc plate, so as to effectively prevent dust from flying around and affecting the transmission efficiency and accuracy of laser, and prevent the power reduction of laser assembly and the occurrence of shallow marking depth; and prompts the sliding plate to scrape and concentrate the dirt intercepted by the inner wall of hollow mesh plate and the dirt scraped into the interior of hollow mesh plate by the sliding intercepting plate, so as to prevent the dirt from being scattered and increasing the possibility of overflow, and prevent the dirt from adhering to the surface of optical lens of laser assembly and causing the lens to absorb heat and overheat and affect the light output quality of light beam.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

A telescopic limit plate 13 is hinged on the side of the telescopic plate 12 away from the L-shaped baffle 11, and a centered friction column 14 is rotatably installed inside the groove of the telescopic end of the telescopic limit plate 13. Through the above cooperation, the L-shaped baffle 11 is used to block the tire and the laser assembly 8 to always be in the same orientation for marking, which simplifies the orientation adjustment of the tire during laser marking and reduces manual participation, avoids the marked data information after the tire is laser marked constantly changing in orientation, affecting the inspection experience of the inspectors at the same perspective, and ensures that the laser assembly 8 operates at low temperature for a long time to reduce usage loss; through the above cooperation, the tire that deviates from the center orientation of the transmission roller 22 is transported in a centered manner by relying on the limited rotation of the centered friction columns 14 on both sides and the limited resistance of the telescopic limit plate 13, preventing the tire and the laser assembly 8 from being in the preset orientation for data marking during the tire marking process, and avoiding misalignment or ambiguity in the data marking of the tire by the laser assembly 8.

[0030] An exhaust assembly is provided on the left side of the outer wall of the L-shaped baffle 11, and an air outlet is provided on the right side of the L-shaped baffle 11. The top of the telescopic end of the elastic telescopic plate 12 contacts the bottom of the L-shaped baffle 11, and a torsion spring is provided between the fixed end of the telescopic limit plate 13 and the fixed end of the elastic telescopic plate 12. A groove is provided at the telescopic end of the telescopic limit plate 13, and an anti-sway device 4 is provided on the inner side of the elastic telescopic plate 12 to ensure good stability of the tire during laser marking.

[0031] When in use, the transmission component 21 is started, and the transmission component 21 drives the transmission roller 22 through the internal motor. The transmission roller 22 drives the tire on its top that needs to be laser marked to move toward the laser component 8. After the tire is transported a distance on the top of the transmission component 21, it passes over the central friction column 14 and then starts the electric telescopic rod 7. The telescopic end of the electric telescopic rod 7 drives the laser component 8 to move downward, and the laser component 8 drives the L-shaped baffle 11 to descend synchronously. At the same time, the exhaust component is started, and the exhaust component sucks and absorbs the dust raised around the laser component 8 through the air outlet on the right side of the L-shaped baffle 11. When the laser marking work starts, the exhaust component stops working to avoid damaging the laser component 8 The L-shaped baffle 11 is used to block the tire and the laser assembly 8 is started to mark the tire. The electric slide 6 is started, and the electric slide 6 drives the electric telescopic rod 7 to slide back and forth inside itself. The electric telescopic rod 7 drives the laser assembly 8 to move synchronously. At the same time, the laser assembly 8 pulls the spiral conveying pipe 10 to move synchronously when it moves downward. During the long uninterrupted process, the water cooling assembly 9 cools the laser assembly 8 through the spiral conveying pipe 10. The above cooperation relies on the obstruction of the L-shaped baffle 11 to ensure that the tire and the laser assembly 8 are always in the same position. The L-shaped baffle 11 moves downward, pressing the elastic telescopic plate 12 to move synchronously at the telescopic end, and the telescopic limit plate 13 on one side of the elastic telescopic plate 12 remains stationary. At the same time, during the tire transportation process, the outer wall of the tire contacts the outer wall of the center friction column 14 to generate friction, and the center friction column 14 starts to rotate due to the friction. At this time, when the tire is in a non-center position of the transmission roller 22, it will resist the center friction column 14. The middle friction column 14, the center friction column 14 resists the telescopic end of the telescopic limit plate 13 through the resistance force to generate a contraction force, and the telescopic end of the telescopic limit plate 13 is reset by the rebound force of the built-in spring and pushes the center friction column 14 to reset. At this time, the center friction column 14 pushes the tire to move toward the center of the transmission roller 22. Through the above cooperation, relying on the limited rotation of the center friction columns 14 on both sides and the limited resistance of the telescopic limit plate 13, the tire that deviates from the center position of the transmission roller 22 is centered and transported, preventing the tire from being difficult to ensure that the tire and the laser component 8 are in the preset position for data marking during the tire marking process, and avoiding the laser component 8 from misaligning or blurring the data marking of the tire.

Several vibration plates 43 are all penetrated and fixedly installed on the outer wall of the fixed rod 42. The top of the fixed end of the telescopic bottom plate 44 is hinged to the bottom of the transmission plate 41, and the bottom of the telescopic bottom plate 44 contacts the top of the transmission assembly 21. The bottom of the arc block 45 is fixedly installed on the top of the fixed end of the telescopic bottom plate 44, and the bottom of the vibration plate 43 is located on the arc surface motion trajectory of the arc block 45. Through the above cooperation, the vibration force of the vibration plate 43 is relied on to reduce the friction blockage phenomenon when the center friction column 14 contacts the outer wall of the tire, so as to prevent the center friction column 14 from being difficult to rotate due to excessive friction or tire orientation deviation, thereby reducing the conveying passability of the tire and reducing the laser marking efficiency.

[0034] The anti-sway device 4 also includes a stabilizing mechanism symmetrically arranged on the telescopic base plate 44 about the transmission plate 41, the stabilizing mechanism includes a rotating wheel 46, a friction plate 47, a rotating rod 48, a U-shaped plate 49, a limiting column 410, an L-shaped through-plate 411, a guide plate 412 and an elastic arc sheet 413. The bottom of the rotating wheel 46 is rotatably mounted on the top edge of the fixed end of the telescopic base plate 44, the friction plate 47 is fixedly mounted on the outer wall of the fixed end of the elastic telescopic plate 12 away from the center of the top plate 31, the bottom of the rotating rod 48 passes through and is fixedly mounted inside the rotating wheel 46, the inside of the U-shaped plate 49 passes through and is slidably mounted on the outer wall of the spiral groove of the rotating rod 48, the inside of the U-shaped plate 49 is threadedly connected to the rotating rod 48, the bottom of the limiting column 410 is fixedly mounted on the top of the fixed end of the telescopic base plate 44, the L-shaped through-plate 4 The top of the fixed end 11 is penetrated by a spring and slidably installed inside the U-shaped plate 49 away from the center of the top plate 31. A U-shaped groove is provided inside the telescopic end of the L-shaped penetrating plate 411. The guide plate 412 is fixedly installed on the outer wall of the L-shaped penetrating plate 411 away from the center of the top plate 31. The outer wall of the elastic arc piece 413 is fixedly installed inside the U-shaped groove in the telescopic end of the L-shaped penetrating plate 411. Through the above cooperation, the U-shaped plate 49 is enabled to clamp the outer wall of the tire stably, and the clamping range of the tire is expanded with the help of the L-shaped penetrating plate 411 and the elastic arc piece 413, thereby improving the clamping and limiting stability of the tire on the original basis, avoiding the shaking of the tire due to equipment vibration or external force interference, thereby causing the laser marked data to be dislocated and broken, and ensuring the integrity of the laser marking.

[0035] There are two friction plates 47. The friction plate 47 is located on the movement trajectory of the outer wall of the rotating wheel 46 near the telescopic bottom plate 44. A spiral groove is provided on the upper part of the outer wall of the rotating rod 48. The outer wall of the limiting column 410 is movable through the interior of the U-shaped plate 49. The top of the U-shaped plate 49 is provided with an anti-pollution device 5 for preventing dirt from interfering with the laser marking process.

[0036] When in use, the telescopic end of the elastic telescopic plate 12 is pressed by the L-shaped baffle 11 and moves downward, driving the transmission plate 41 to move synchronously. The transmission plate 41 is restricted by the telescopic bottom plate 44, prompting the hinge axis between itself and the elastic telescopic plate 12 to start rotating. At this time, the bottom of the transmission plate 41 pushes the telescopic bottom plate 44 to slide along the top of the transmission assembly 21 toward the center of the top plate 31, and the telescopic bottom plate 44 drives the arc block 45 to move synchronously. During the movement, the arc surface of the arc block 45 contacts the arc surface at the bottom of the vibration plate 43. The vibration plate 43 is limited by the fixing rod 42 to ensure it is stationary, but the bottom of the vibration plate 43 is The arc block 45 starts to bend and deform due to the resistance. When the arc block 45 passes over the vibration plate 43 and resets itself through its own toughness, it will swing back and forth to generate vibration, and the center friction column 14 is prompted to vibrate synchronously through the transmission of force. Through the above cooperation, the vibration force of the vibration plate 43 is relied on to reduce the friction blockage phenomenon when the center friction column 14 contacts the outer wall of the tire, and prevent the center friction column 14 from being difficult to rotate due to excessive friction or tire orientation deviation, thereby reducing the conveying passability of the tire and reducing the laser marking efficiency; when the telescopic bottom plate 44 slides toward the center of the top plate 31, it drives the rotating wheel 46 to move synchronously, and the rotating wheel 46 contacts the inner wall of the friction plate 47 The contact generates friction and starts to rotate, the rotating wheel 46 drives the rotating rod 48 to rotate, and the rotating rod 48 restricts the U-shaped plate 49 through the spiral groove on the outer wall. The rotating rod 48 rotates to drive the U-shaped plate 49 to slide downward and is restricted by the limiting column 410. At this time, the U-shaped plate 49 drives the L-shaped through-plate 411 to move synchronously, that is, the L-shaped through-plate 411 moves toward the center direction of the transmission roller 22 during tire transportation, and the telescopic end of the L-shaped through-plate 411 drives the guide plate 412 to move synchronously. After the arc surface of the guide plate 412 contacts the outer wall of the tire, a resistance force is generated, which prompts the telescopic end of the L-shaped through-plate 411 to start to shrink, and the L-shaped through-plate 411 passes through the self- The rebound force of the built-in spring continuously presses the outer wall of the tire to limit it. At the same time, the L-shaped through-plate 411 drives the elastic arc piece 413 to move downward and contacts the edge of the outer wall of the tire to cause deformation and always stick to the irregular tooth marks on the edge of the tire. Through the above cooperation, the U-shaped plate 49 is prompted to clamp the outer wall of the tire stably, and with the help of the L-shaped through-plate 411 and the elastic arc piece 413, the clamping range of the tire is expanded, and the clamping and limiting stability of the tire is improved on the original basis, avoiding the shaking of the tire due to equipment vibration or external force interference, thereby causing the laser-marked data to be dislocated and broken, thereby ensuring the integrity of the laser marking.

The bottom of the hollow mesh plate 51 is fixedly mounted on the top of the U-shaped plate 49. The outer wall of the sliding intercepting plate 52 passes through and is slidably mounted inside the hollow mesh plate 51. A square groove is provided below the sliding intercepting plate 52. The bottom of the hinged rod 53 is hinged to the top edge of the L-shaped through-plate 411. The top of the hinged rod 53 is hinged to the outer wall of the sliding intercepting plate 52. The bottom of the contact plate 54 is fixedly mounted on the sliding intercepting plate 5 2 top, the bottom of the curved plate 55 is hinged to the outer wall of the hollow mesh plate 51 by a torsion spring, and the top of the inner wall of the curved plate 55 is located on the movement trajectory of the resistance plate 54. Through the above cooperation, the sliding interception plate 52 is used to expand the interception range of the dust brought by the hollow mesh plate 51 during the laser marking process of the laser assembly 8 on the tire. At the same time, the overflowing dust is blocked by the curved plate 55, effectively preventing the dust from flying around and affecting the transmission efficiency and accuracy of the laser, and preventing the power reduction of the laser assembly 8 from causing the marking depth to be too shallow.

[0039] The anti-pollution device 5 also includes a round wheel 56, a cross bar 57, a sliding plate 58 and a limiting rod 59. The round wheel 56 is rotatably mounted on the outer wall of the sliding intercepting plate 52 near the center of the hollow mesh plate 51 (such as Figure 9 As shown in the figure, both ends of the cross bar 57 are fixedly mounted at the center of the inner wall of the circular wheel 56, the sliding plate 58 passes through the inside and is fixedly mounted on the outer wall of the cross bar 57, and both ends of the limiting rod 59 are fixedly mounted on the inner wall of the sliding intercepting plate 52. Through the above cooperation, the sliding plate 58 is prompted to scrape and concentrate the dirt intercepted by the inner wall of the hollow mesh plate 51 and the dirt scraped into the interior of the hollow mesh plate 51 by the sliding intercepting plate 52 when it is reset, so as to prevent the dirt from being scattered everywhere and increasing the possibility of overflow, and to avoid the dirt from adhering to the surface of the optical lens of the laser assembly 8, causing the lens to absorb heat and overheat, affecting the light output quality of the light beam.

[0040] The outer wall of the circular wheel 56 contacts the inner wall of the hollow mesh plate 51, and a number of reciprocating spiral grooves are equidistantly opened on the outer wall of the cross bar 57. The inside of the sliding plate 58 contacts the reciprocating spiral grooves on the outer wall of the cross bar 57. The side of the sliding plate 58 close to the sliding intercepting plate 52 contacts the inner wall of the hollow mesh plate 51, and the outer wall of the limiting rod 59 moves through the interior of the sliding plate 58.

[0041] When the U-shaped plate 49 is in use, it drives the hollow mesh plate 51 to move synchronously when the U-shaped plate 49 moves toward the center of the top plate 31, and the hollow mesh plate 51 drives the sliding intercepting plate 52 to move synchronously. At this time, the hinged rod 53 is pushed and limited by the L-shaped through-plate 411, causing its own hinge axis to start to rotate. At this time, the hinged rod 53 rotates through the hinge axis to push the sliding intercepting plate 52 to slide upward along the inner wall of the hollow mesh plate 51. When the sliding intercepting plate 52 moves upward, it drives the resistance plate 54 to move synchronously. When the resistance plate 54 moves upward, it resists the arc surface of the arc plate 55, causing the hinge axis between the arc plate 55 and the hollow mesh plate 51 to start rotating, causing the arc plate 55 to rotate in an arc shape with the hinge axis as the axis center toward the outer wall of the hollow mesh plate 51. Through the above cooperation, the sliding intercepting plate 52 is used to expand the interception range of dust driven by the hollow mesh plate 51 during the laser marking process of the laser assembly 8 on the tire. At the same time, the overflowing dust is blocked by the arc plate 55, effectively preventing the dust from flying around and affecting The transmission efficiency and accuracy of the laser can prevent the power drop of the laser component 8 from causing the marking depth to be too shallow; when the sliding intercepting plate 52 moves upward, it drives the circular wheel 56 to move synchronously. When the circular wheel 56 contacts the inner wall of the hollow mesh plate 51, friction is generated and it starts to rotate, and the circular wheel 56 drives the cross bar 57 to rotate. When the cross bar 57 rotates, it limits the sliding plate 58 through the reciprocating spiral groove on its own outer wall, and the built-in block of the sliding plate 58 constantly contacts the inner wall of the reciprocating spiral groove. At the same time, the sliding plate 58 is limited by the limiting rod 59, which enables the sliding plate 58 to slide horizontally along the outer wall of the reciprocating spiral groove of the cross bar 57. Through the above cooperation, the sliding plate 58 is prompted to scrape and concentrate the dirt intercepted by the inner wall of the hollow mesh plate 51 and the dirt scraped into the inside of the hollow mesh plate 51 by the sliding intercepting plate 52, preventing the dirt from being scattered everywhere and increasing the possibility of overflow, and preventing the dirt from adhering to the surface of the optical lens of the laser component 8, causing the lens to absorb heat and overheat, affecting the light output quality of the light beam.
