Description

Technical Field

[0001] This invention relates to the field of metal laser cutting technology, specifically to a laser engraving device for the texture of tire mold sidewalls. Background Technology

[0002] As the precision requirements for tire mold manufacturing continue to increase, laser cutting has gradually replaced traditional machining methods for the fine engraving and shaping of complex textures on tire sidewalls. Although existing laser cutting equipment has improved processing efficiency and texture accuracy, it still has significant shortcomings in intelligent control and process coordination: most rely on manual or independent electronic control systems to complete mold clamping, station feed, and laser head start / stop control, lacking intelligent sequential linkage and adaptive positioning capabilities, which easily leads to problems such as clamping eccentricity, positioning deviation, and accidental triggering of processing.

[0003] Patent publication number CN223250793U describes a system where an X-axis support plate drives a Z-axis mechanism to move along the X-axis, a Z-axis support plate drives a laser module to move along the Z-axis, and a rotary table drives the workpiece to rotate around the rotary table's axis. The laser module's 3D galvanometer includes a Z1-axis optical system, an X1-axis galvanometer, and a Y1-axis galvanometer. The control system, based on a preset graphic template in the host computer software, converts the preset graphic template into drive signals via a control board. These drive signals control the X1-axis galvanometer to deflect around the X1-axis, the Y1-axis galvanometer to deflect around the Y1-axis, and the beam expander to move along the Z1-axis, causing the combined movement of the X1-axis galvanometer, Y1-axis galvanometer, and Z1-axis beam expander. The laser beam generated by the laser first passes through a beam expander and a focusing lens to change its focusing position, then is refracted by the X1-axis and Y1-axis galvanometers and passes through a field lens to rapidly move on the workpiece's curved surface within the scanning and engraving area for three-dimensional surface engraving. This system boasts high efficiency and high quality.

[0004] The above technical solution has obvious limitations in practice: if mechanical limiting is not performed at the initial position of the fixture, spontaneous movement will occur due to lead screw clearance, equipment vibration, or external force contact, leading to dangerous situations such as empty stroke impacting the laser head, tooling misalignment, and mold moving before it is placed stably. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a laser engraving device for tire mold sidewall textures, which solves the problems mentioned in the background art, such as spontaneous movement due to lead screw clearance, equipment vibration, or external force contact if mechanical limiting is not performed at the initial position of the fixture, leading to empty stroke impacting the laser head, tooling misalignment, and mold movement before it is stable.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a laser engraving device for tire mold sidewall texture, comprising a base frame, a model, a mounting base for mounting a laser head, a first driving mechanism for moving the mounting base, and a second driving mechanism mounted on the base frame. The tire mold sidewall texture laser engraving device further comprises: a processing mechanism mounted on the base frame and driven by the second driving mechanism, used for intelligent laser cutting processing of the model; the processing mechanism includes a placement seat mounted on the second driving mechanism, a chuck rotatably mounted on the placement seat for internal support of the model, a slide rail mounted in the second driving mechanism, a load-bearing rod slidably mounted on the placement seat, an elastic telescopic rod mounted on the base frame, a limiting ring mounted on the elastic telescopic rod, a sliding groove plate mounted on the limiting ring, and an extension plate mounted on the load-bearing rod; the limiting ring matches the slide rail.

[0007] In the above embodiments, at the initial position of the placement seat, the limiting ring contacts the slide rail, so that the placement seat is within the limiting range of the limiting ring, and the position of the placement seat cannot be moved.

[0008] According to the above technical solution, the processing mechanism further includes a connecting frame mounted on the placement seat, a gripper slidably mounted on the connecting frame, and a pulley disposed on the gripper; the pulley contacts the model; the pulley is used to assist the model in rotating when the chuck drives the model to rotate.

[0009] In the above embodiment, the pulleys on the gripper contact the outer wall of the model to perform external clamping, so that the clamping is triggered by the model's own gravity. The model is internally supported by the chuck, and the chuck can be driven to rotate by an external power source to rotate the entire model, so that it can be rotated for laser cutting during subsequent laser head engraving.

[0010] According to the above technical solution, the processing mechanism further includes a translation rack mounted on the gripper, a vertical rack mounted on the load-bearing rod, a gear carrier mounted on the placement seat, and a contact rod mounted on the connecting frame; the translation rack meshes with the gear carrier; the vertical rack meshes with the gear carrier.

[0011] In the above embodiment, the load-bearing rod moves downward while driving the vertical rack to move downward. The downward movement of the vertical rack drives the gear carrier to rotate counterclockwise. The counterclockwise rotation of the gear carrier drives the translation racks on both sides to move, causing the translation racks to drive the grippers on both sides to move towards the model.

[0012] According to the above technical solution, the tire mold sidewall texture laser engraving equipment further includes a limiting mechanism and an absorption mechanism; the limiting mechanism is installed on the base frame and is used to self-lock and protect the initial position of the laser head; the absorption mechanism is installed on the base frame and is used to absorb the fumes generated during laser head engraving.

[0013] According to the above technical solution, the limiting mechanism includes a round rod mounted on the mounting base, a fixed bracket mounted on the base frame, an extension seat mounted on the mounting base, and a slot formed on the extension seat.

[0014] In the above embodiments, the laser head mounted on the mounting base is initially positioned on the left side of the base frame, and its movement is restricted by the non-sloping surface of the pawl through the slot on the extension base.

[0015] According to the above technical solution, the limiting mechanism further includes a hollow frame mounted on a fixed frame, a slidably mounted claw in the hollow frame, and a receiving button mounted on the claw; a first spring is provided between the claw and the hollow frame, and the claw is reset by the first spring; the claw matches the groove opened in the slot; the contact surface between the claw and the extension seat is set as an inclined surface.

[0016] In the above embodiment, when the placement seat moves the contact rod, the contact rod will contact the receiving button, causing the receiving button to move the claw along the inner wall of the hollow frame, while compressing the No. 1 spring, causing the claw to disengage from the slot. At this time, the drive mechanism can normally drive the mounting seat to move.

[0017] According to the above technical solution, the absorption mechanism includes a limiting plate mounted on the base frame, an inclined slot frame slidably mounted on the limiting plate, and a fixing plate mounted on the inclined slot frame; the inclined slot frame is in contact with the round rod.

[0018] In the above embodiment, the movement of the round rod causes the inclined slot frame to be subjected to force and descend vertically along the limiting plate, and the movement of the inclined slot frame drives the fixed plate to move at the same time.

[0019] According to the above technical solution, the absorption mechanism further includes a telescopic tube installed on the base frame, an inlet installed on the telescopic tube, a slot provided on the fixed plate, and a pin for connecting the inlet and the fixed plate; the pin matches the groove opened in the slot.

[0020] In the above embodiment, the movement of the fixed plate causes the suction port to move and stretches the telescopic tube, so that the suction port moves synchronously with the laser head. The suction port and the fixed plate can be quickly connected by inserting a pin into the slot.

[0021] According to the above technical solution, the absorption mechanism further includes a limiting block installed on the pin, a slide rod slidably installed on the fixed plate, and a positioning block installed on the slide rod.

[0022] In the above embodiment, when the limiting block moves, it will contact the inclined surface of the positioning block, causing the positioning block to be forced to move the sliding rod and simultaneously stretch the second spring. At this time, the limiting block continues to move, causing the positioning block to be inserted into the limiting block through the second spring. At this time, the position of the pin is fixed and cannot be inserted or removed normally.

[0023] According to the above technical solution, a second spring is provided between the slide rod and the fixed plate, and the slide rod is driven to reset by the second spring; the groove opened by the positioning block and the limiting block are matched; the contact surface between the positioning block and the limiting block is set as an inclined surface.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, by setting up a processing mechanism, the self-weight of the mold triggers adaptive external clamping and sequential unlocking, realizing intelligent clamping and positioning without manual intervention. Combined with laser cutting processing, the tire mold sidewall plate automatically completes centering, clamping, and station preparation before processing, improving the consistency of the laser cutting path and the degree of intelligent automation. Utilizing the intelligent interlocking logic of mechanical limit and gravity linkage, it is ensured that the placement seat can only move and enter the laser cutting station after the mold is reliably placed and clamped, avoiding damage to the laser cutting head and mold caused by erroneous actions, and ensuring the safety and stability of the laser cutting process. The mold can be internally supported by a chuck, and the chuck can be driven to rotate by an external power source, causing the entire model to rotate, so that it can be rotated for processing during subsequent laser head engraving.

[0025] 2. In this invention, by setting up a limiting mechanism, the laser head is initially locked outside the working range and cannot move when not processing. This completely avoids the laser head accidentally scratching the tire side plate mold, colliding with the tooling, or damaging the laser head when the equipment is powered on, debugged, or unloaded. Only after the placement seat reaches the designated position can the drive mechanism drive the mounting seat to move normally. With the model not placed, the placement seat does not move, and the laser head does not unlock, forming a complete safety chain. After the laser head is reset, it is automatically limited again, avoiding accidental movement of the laser head due to equipment vibration, lead screw retraction, program abnormalities, etc., preventing the laser head from colliding, and greatly improving the safety of equipment operation.

[0026] 3. In this invention, the absorption mechanism generates a certain amount of fumes during laser head operation. The suction port is located outside the workstation area and can move synchronously with the laser head, allowing for timely suction of the fumes as soon as they are generated. This prevents the fumes from spreading and contaminating the mold surface, laser lens, and equipment interior, ensuring a clear laser engraving path and stable processing accuracy. It also improves the operating environment. Through quick installation of the suction port and anti-accidental contact measures, the absorption mechanism maintains a rigid position during processing, preventing displacement due to vibration or airflow backlash. This eliminates friction or collision with the tooling, protecting both the equipment and the workpiece. When disassembling the suction port, pulling the sliding rod outwards disengages the positioning block from the limit block, allowing for normal insertion and removal of the pins. The purely mechanical quick-installation structure allows for tool-free assembly and disassembly of the absorption mechanism, facilitating cleaning blockages, filter replacement, and pipeline maintenance, significantly reducing equipment downtime for maintenance.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: Please see Figures 1-11 One embodiment of the present invention is: a laser engraving device for tire mold sidewall texture, including a base frame 1, a model 7, a mounting seat 3 for mounting a laser head 4, a drive mechanism 2 for driving the mounting seat 3 to move, and a drive mechanism 5 mounted on the base frame 1. The tire mold sidewall texture laser engraving device further includes: a processing mechanism, mounted on the base frame 1 and driven by the drive mechanism 5, for intelligent laser cutting processing of the model 7; the processing mechanism includes a placement seat 10 mounted on the drive mechanism 5, a chuck 6 rotatably mounted on the placement seat 10 for internal support of the model 7, a slide rail 11 mounted in the drive mechanism 5, a load-bearing rod 12 slidably mounted on the placement seat 10, an elastic telescopic rod 13 mounted on the base frame 1, a limiting ring 14 mounted on the elastic telescopic rod 13, a sliding groove plate 15 mounted on the limiting ring 14, and an extension plate 16 mounted on the load-bearing rod 12; the limiting ring 14 matches the slide rail 11.

[0031] In the above embodiments, the placement seat 10 cannot be moved in its initial position and will not be displaced due to accidental touch, lead screw shaking or other unexpected events, thus ensuring the stability of the positioning reference before engraving and avoiding laser engraving misalignment and equipment collision.

[0032] The processing mechanism also includes a connecting frame 17 mounted on the placement seat 10, a gripper 18 slidably mounted on the connecting frame 17, and a pulley 19 disposed on the gripper 18; the pulley 19 contacts the model 7; the pulley 19 is used to assist the rotation of the model 7 when the chuck 6 drives the model 7 to rotate.

[0033] In the above embodiments, the clamping is triggered by the gravity of the model 7 itself, without the need for an additional power source, and it can adapt to tire sidewall molds with different outer diameters.

[0034] The machining mechanism also includes a translation rack 110 mounted on the gripper 18, a vertical rack 111 mounted on the load-bearing rod 12, a gear carrier 112 mounted on the placement seat 10, and a contact rod 113 mounted on the connecting frame 17; the translation rack 110 meshes with the gear carrier 112; the vertical rack 111 meshes with the gear carrier 112.

[0035] In the above embodiments, the adaptive external clamping and sequential unlocking are triggered by the mold's own weight, realizing intelligent clamping and positioning without manual intervention. Combined with laser cutting processing, the tire mold sidewall plate can automatically complete centering, clamping and station preparation before processing, improving the consistency of the laser cutting path and the degree of intelligent automation.

[0036] The tire mold sidewall texture laser engraving equipment also includes a limiting mechanism and an absorption mechanism; the limiting mechanism is installed on the base frame 1 and is used to self-lock and protect the initial position of the laser head 4; the absorption mechanism is installed on the base frame 1 and is used to absorb the fumes generated by the laser head 4 during engraving.

[0037] In this embodiment, during operation: the laser head 4 on the mounting base 3 is moved by the first driving mechanism 2, but the initial position of the laser head 4 is limited. The second driving mechanism 5 drives the placement base 10 to move along the slide rail 11, allowing the laser head 4 to move left and right along the base frame 1, while the placement base 10 moves back and forth along the base frame 1. At the initial position of the placement base 10, it contacts the slide rail 11 through the limiting ring 14, keeping the placement base 10 within the limiting range of the limiting ring 14. This prevents the placement base 10 from being moved, thus preventing displacement due to accidental contact, lead screw wobbling, or other unexpected events. This ensures the stability of the positioning reference before engraving, avoiding laser engraving misalignment and equipment collisions. When no model 7 is placed on the placement seat 10, the load-bearing rod 12 at the placement seat 10 is pushed out by the limiting ring 14 supported by the elastic telescopic rod 13. That is, the sliding plate 15 pushes the load-bearing rod 12 out of the placement seat 10. Then, by placing the model 7 on the load-bearing rod 12 or the extension plate 16, the weight of the model 7 causes the load-bearing rod 12 to move downward. The downward movement of the load-bearing rod 12 contacts the sliding plate 15, thereby pressing the sliding plate 15 and forcing the limiting ring 14 to move synchronously. At this time, the placement seat 10 is released from the restriction of the limiting ring 14. Only when the model 7 is correctly placed is the limiting ring 14 unlocked, and the placement seat 10 can be driven to move. If no model 7 is placed or is not placed in the correct position, it will remain locked to prevent empty placement. Risks such as stroke displacement, feeding without clamping, and continued operation even when model 7 is loose can be mitigated by the free movement of drive mechanism 5. The movement of the placement seat 10 causes the load-bearing rod 12 to move along the slide plate 15, ensuring that the limiting ring 14 remains disengaged from the placement seat 10 throughout its movement. This prevents the limiting ring 14 from being reset within the placement seat 10's range via the elastic telescopic rod 13, thus avoiding movement interference. Simultaneously, the downward movement of the load-bearing rod 12 drives the vertical rack 111 downward. This downward movement of the vertical rack 111 drives the gear carrier 112 to rotate counterclockwise, which in turn moves the translation racks 110 on both sides. The translation rack 110 causes the jaws 18 on both sides to move towards the model 7, and finally the pulleys 19 on the jaws 18 contact the outer wall of the model 7, thereby performing external clamping. The clamping is triggered by the gravity of the model 7 itself, without the need for an additional power source. It is adaptable to tire sidewall molds with different outer diameters. The model 7 is internally supported by the chuck 6, and the chuck 6 can be driven to rotate by an external power source, which will drive the entire model 7 to rotate. This allows it to rotate for laser cutting during subsequent laser head 4 engraving. Then, the drive mechanism 2 5 drives the model 7 to the working position of the laser head 4, that is, the placement seat 10 moves, which drives the connecting frame 17 and the contact rod 113 on the connecting frame 17 to move synchronously.

[0038] Example 2: Please see Figures 1-11Based on the above embodiments, in another embodiment of the present invention, the limiting mechanism includes a round rod 20 mounted on the mounting base 3, a fixing bracket 21 mounted on the base frame 1, an extension seat 22 mounted on the mounting base 3, and a slot 23 formed on the extension seat 22.

[0039] In the above embodiments, the laser head 4 is initially locked outside the working range and cannot be moved when not processing, thus completely avoiding the laser head 4 from accidentally scratching the tire sidewall mold, colliding with the tooling, or damaging the laser head 4 when the equipment is powered on, debugged, or unloaded.

[0040] The limiting mechanism also includes a hollow frame 24 mounted on the fixed frame 21, a claw 25 slidably mounted in the hollow frame 24, and a receiving button 26 mounted on the claw 25; a first spring is provided between the claw 25 and the hollow frame 24, and the claw 25 is driven to reset by the first spring; the claw 25 matches the slot opened in the slot 23; the contact surface between the claw 25 and the extension seat 22 is set as an inclined surface.

[0041] In the above embodiments, the laser head 4 is automatically limited when it returns to its initial position after each processing, which avoids the laser head 4 from moving unexpectedly due to equipment vibration, lead screw retraction, program abnormalities, etc., and prevents the laser head 4 from colliding, thus greatly improving the safety of equipment operation.

[0042] In this embodiment, during operation: the laser head 4 mounted on the mounting base 3 is initially positioned on the left side of the base frame 1, and is restricted by the non-sloping surface of the pawl 25 through the slot 23 on the extension seat 22, thus restricting the movement of the mounting base 3. Movement of the mounting base 3 causes the round rod 20 to move synchronously. The laser head 4 is initially locked outside the working range and cannot move when not processing, completely preventing accidental movement of the laser head 4 during power-on, debugging, or no-load operation, thus avoiding scratches on the tire sidewall mold, collisions with tooling, or damage to the laser head 4. When the placement seat 10 moves the contact rod 113, the contact rod 113 contacts the receiving button 26, causing the receiving button 26 to move the pawl 25 along the inner wall of the hollow frame 24, simultaneously compressing the first spring, causing the pawl 25 to disengage from the slot 23. At this time, the drive mechanism 2 can drive normally. The moving mounting base 3 moves while the model 7 is not placed, the placement base 10 remains stationary, and the laser head 4 remains unlocked, forming a complete safety chain. After the laser head 4 resets, when the extension base 22 moves, it will contact the inclined surface of the chuck 25, causing the chuck 25 to move along the inner wall of the hollow frame 24 under force, while simultaneously compressing the first spring. When the center points of the slot 23 and the chuck 25 overlap, the compressed first spring is released, resetting and driving the chuck 25 to insert into the slot 23, thus re-limiting the mounting base 3. After each processing, the laser head 4 returns to its initial position and is automatically limited, preventing the laser head 4 from accidentally moving due to equipment vibration, lead screw retraction, program abnormalities, etc., and preventing the laser head 4 from colliding, greatly improving the safety of equipment operation.

[0043] Example 3: Please see Figures 1-11 Based on the above embodiments, in another embodiment of the present invention, the absorption mechanism includes a limiting plate 30 mounted on the base frame 1, a sloping groove frame 31 slidably mounted on the limiting plate 30, and a fixing plate 32 mounted on the sloping groove frame 31; the sloping groove frame 31 is in contact with the round rod 20.

[0044] The absorption mechanism also includes a telescopic tube 33 mounted on the base frame 1, an inlet 34 mounted on the telescopic tube 33, a slot 35 provided on the fixed plate 32, and a pin 36 for connecting the inlet 34 and the fixed plate 32; the pin 36 matches the groove opened in the slot 35.

[0045] In the above embodiment, the suction port 34 moves synchronously with the laser head 4, and can be sucked away in time when the smoke is generated, so as to avoid the smoke from spreading and contaminating the mold surface, laser lens and equipment interior, ensuring clear laser engraving path and stable processing accuracy, while improving the operating environment.

[0046] The absorption mechanism also includes a limiting block 37 mounted on the pin 36, a slide bar 38 slidably mounted on the fixed plate 32, and a positioning block 39 mounted on the slide bar 38.

[0047] In the above embodiments, the absorption mechanism is kept in a rigid position during processing, preventing displacement due to vibration or airflow backlash, thus eliminating friction or collision with the tooling and protecting the equipment and workpiece.

[0048] A second spring is provided between the slide rod 38 and the fixed plate 32, and the slide rod 38 is reset by the second spring; the positioning block 39 matches the groove opened by the limiting block 37; the contact surface between the positioning block 39 and the limiting block 37 is set as an inclined surface.

[0049] In the above embodiment, when disassembling the suction port 34, the sliding rod 38 is pulled outward to disengage the positioning block 39 from the limiting block 37. At this time, the pin 36 can be inserted and removed normally to complete the disassembly. The pure mechanical quick-installation structure allows the absorption mechanism to be disassembled and installed without tools, which is convenient for cleaning blockages, replacing filter elements, and repairing pipelines, and significantly reduces equipment downtime for maintenance.

[0050] In this embodiment, during operation, the laser head 4 generates a certain amount of fumes. The movement of the round rod 20 causes the inclined slot frame 31 to descend vertically along the limiting plate 30 under pressure. Simultaneously, the movement of the inclined slot frame 31 moves the fixed plate 32, which in turn moves the suction port 34 and extends the telescopic tube 33. This allows the suction port 34 to move synchronously with the laser head 4, ensuring timely removal of fumes as soon as they are generated. This prevents fumes from spreading and contaminating the mold surface, laser lens, and equipment interior, ensuring a clear laser engraving path and stable processing accuracy, while also improving the operating environment. The suction port 34 and the fixed plate 32 can be quickly connected by inserting the pin 36 into the slot 35. Specifically, after the suction port 34 and the fixed plate 32 are aligned, the pin 36 is inserted into the slot 35. During insertion, the movement of the pin 36 causes a limiting action. When block 37 moves, the limiting block 37 will contact the inclined surface of the positioning block 39, causing the positioning block 39 to be forced to move the sliding rod 38 and simultaneously stretch the second spring. At this time, the limiting block 37 continues to move, causing the positioning block 39 to be inserted into the limiting block 37 through the second spring. At this time, the position of the pin 36 is fixed and cannot be inserted or removed normally, so that the absorption mechanism maintains rigid positioning during processing and will not be displaced due to vibration or airflow backflow. It also prevents friction or collision with the tooling, protecting the equipment and the workpiece. When disassembling the suction port 34, the sliding rod 38 is pulled outward to cause the positioning block 39 to disengage from the limiting block 37. At this time, the pin 36 can be inserted or removed normally to complete the disassembly. The pure mechanical quick-installation structure allows the absorption mechanism to be disassembled and assembled without tools, which is convenient for cleaning blockages, replacing filter elements, and repairing pipelines, significantly reducing equipment downtime for maintenance.
