[0001] The present invention relates to the technical field of tire forming, and particularly relates to a debugging tooling and a debugging method for a laser marking device based on tire forming. Background Art

[0002] Tire forming equipment is used to produce tires and has multiple production processes such as conveying, cutting, and laminating. With the development of tire forming equipment, a laser marking device for guiding the process during the forming process has also become an indispensable part of the whole machine equipment. The laser marking device is mainly used to achieve spatial positioning during the tire forming process, and guides the tire forming size and position through three-level laser beam bundles, providing an accurate positioning standard for the forming process and improving the parameter replacement efficiency and accuracy during the tire forming process. Therefore, before the laser marking device is applied to a tire forming machine, it is necessary to debug and calibrate the laser marking device to ensure the accuracy of the laser beacon debugging, the convenience and stability of the forming process.

[0003] However, the current debugging of the laser marking device is still manually adjusted, without a complete and standardized adjustment method, and is highly dependent on the experience of the staff, resulting in low accuracy and debugging efficiency.

[0004] It can be seen that the existing debugging method for the laser marking device has problems of low accuracy and low debugging efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing debugging method for the laser marking device has problems of low accuracy and low debugging efficiency.

[0007] A mounting bracket provided with a connector adapted for horizontal installation of the laser marking device; and,

[0008] A debugging device including a transverse movement mechanism, a telescopic mechanism, and a drum surface assembly connected in sequence. The drum surface assembly is provided with a scale for receiving the vertical optical path of the laser lamp. The scales are arranged in three from top to bottom, and the projections of the three scales on the horizontal plane are parallel, and the scale lines of the three scales are completely aligned;

[0009] When the transverse movement mechanism operates, it drives the telescopic mechanism and the drum surface assembly to move horizontally. When the telescopic mechanism operates, it drives the drum surface assembly to longitudinally expand and contract.

[0010] In a preferred embodiment, the drum surface assembly is provided with a plurality of arc-shaped members, and each of the arc-shaped members is coaxially arranged and forms an arc-shaped drum surface. Each scale is parallel to the central axis of the drum surface assembly and is horizontally connected to each arc-shaped member.

[0011] In another preferred embodiment, the debugging device includes a chassis, and at least one set of guide rails 241 is provided on the chassis. The transverse movement mechanism includes:

[0012] A first driving member, which is arranged on the chassis; and,

[0013] A transverse movement frame, which is in transmission connection with the first driving member. When the first driving member acts, it drives the transverse movement frame to slide on the guide rails.

[0014] In another preferred embodiment, a guiding member is provided on the transverse movement mechanism, and the guiding member is inclined. The expansion and contraction mechanism includes:

[0015] A second driving member, which is arranged on the transverse movement mechanism; and,

[0016] An expansion and contraction frame, which is in transmission connection with the second driving member. When the second driving member acts, it drives the expansion and contraction frame to slide on the guiding member, and the drum surface assembly is connected to the expansion and contraction frame.

[0017] In another preferred embodiment, a photosensitive sensor or a red marker is provided at a preset integer position on each scale.

[0018] In another preferred embodiment, the connecting member is provided with a connecting portion and a positioning portion adapted to the laser line marker, and the connecting portion is detachably connected to the laser line marker.

[0019] In another preferred embodiment, the mounting frame includes a frame body and a cross beam, the height of the cross beam is adjustable and arranged on the frame body, and the connecting member is mounted on the cross beam.

[0020] The present invention also provides a debugging method for a laser line marker based on tire forming, including the following steps:

[0021] Install the laser line marker on the connecting member, turn on the central laser lamp and the laser lamps on both sides of the laser line marker, and adjust the three laser lamps so that their optical paths are all perpendicular to the scale and emitted;

[0022] Adjust each laser lamp so that the optical paths of the same laser lamp have the same scale on the three scales;

[0023] Start the transverse movement mechanism to make the drum surface assembly move horizontally until the predetermined scale O of the scale is aligned with the optical path of the central laser lamp, and record that the scale readings corresponding to the optical paths of the three laser lamps are M 1 、O、M 2 ;

[0024] Start the expansion and contraction mechanism to move the drum surface assembly longitudinally away from the laser marking device by a predetermined distance S. At this time, the scale graduations corresponding to the optical paths of the three laser lamps are M 11 , O 1 , M 21 , and fine-tune each laser lamp so that O 1 = O, M 11 = M 1 , M 21 = M 2 ;

[0025] Start the laser marking device to move the laser lamps on both sides laterally by a standard distance A. The scale graduations corresponding to the optical paths of the laser lamps on both sides are N 1 , N 2 , then the moving distance of the optical paths of the two laser lamps is M 1 N 1 , M 2 N 2 , if M 1 N 1 ≠ A or M 2 N 2 ≠ A, adjust the guide rail where the laser lamp is located. After resetting, move the laser lamps on both sides again until M 1 N 1 = M 2 N 2 = A.

[0026] In a preferred embodiment, after starting the expansion and contraction mechanism, the drum surface assembly continues to move longitudinally away from the laser marking device, moving more than two predetermined distances S, and corresponding to completing fine-tuning of the laser lamp more than twice.

[0027] In another preferred embodiment, if M 1 N 1 ≠ A or M 2 N 2 ≠ A, adjust one end of the guide rail to make it shift upward, and re-measure the moving distance of the optical paths of the two laser lamps:

[0028] If the error between the moving distance of the optical path and A becomes larger, then adjust this end to shift downward;

[0029] If the error between the moving distance of the optical path and A becomes smaller, then continue to adjust this end to make it shift upward until the moving distance of the optical path is consistent with A.

Specific Embodiments

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application. The debugging tooling and debugging method for a laser marking device based on tire forming provided by the present invention not only have higher adjustment accuracy and more standardized debugging processes, but also improve the debugging efficiency. The present invention will be described in detail below with reference to the accompanying drawings of the specification and specific embodiments.

[0042] To overcome the problems of low accuracy and low debugging efficiency in the debugging method of laser marking devices in the prior art, refer to Figure 1 and Figure 2 , the present invention provides a debugging tooling for a laser marking device based on tire forming, including a mounting frame 10 and a debugging device 20. The mounting frame 10 is used to mount the laser marking device, and the debugging device 20 scales the optical path position of the laser lamp to facilitate adjusting the orientation of the laser lamp.

[0043] The mounting frame 10 is provided with a connector 11 adapted to the horizontal installation of the laser marking device. The mounting frame 10 is designed to imitate the gantry of the tire forming machine, aiming to horizontally install the laser marking device. Generally, the laser marking device is provided with a central laser lamp and laser lamps on both sides. When the forming machine is running, the central laser lamp does not need to move and serves as a central lamp mark to provide a debugging reference for the movement of the laser lamps on both sides. The optical paths of the three laser lamps together form the marking positions required by the process.

[0044] The debugging device 20 includes a transverse movement mechanism 21, a telescopic mechanism 22, and a drum surface assembly 23 connected in sequence. The drum surface assembly 23 is provided with a scale 231 for receiving the vertical optical path of the laser lamp. The scale 231 is arranged in three from top to bottom, and the projections of the three scales 231 on the horizontal plane are parallel, and the scale lines of the three scales 231 are completely aligned. Each laser lamp will form a marking on the drum surface assembly 23. Since the laser lamp emits a fan-shaped optical path, it can cover the three scales 231. The fan-shaped optical path should be perpendicular to the scale, and its projection on the horizontal plane is a straight line. The correct orientation of the laser lamp can keep the scales of the three scales 231 consistent. If they are not consistent, the orientation of the laser lamp should be adjusted.

[0045] The transverse movement mechanism 21 operates to drive the expansion and contraction mechanism 22 and the drum surface assembly 23 to move horizontally; the expansion and contraction mechanism 22 operates to drive the drum surface assembly 23 to expand and contract longitudinally. The drum surface assembly 23 is designed by imitating the mechanical drum of a tire building machine. The drum surface assembly 23 should maintain the same arc-shaped outer shape as the mechanical drum of the corresponding tire building machine. The transverse movement mechanism 21 and the expansion and contraction mechanism 22 can drive the drum surface assembly 23 to complete horizontal and longitudinal movements, thereby enabling the drum surface assembly 23 to highly simulate the movement of the mechanical drum.

[0046] In the present invention, before the laser marking device is applied to a tire building machine, the laser lamp of the laser marking device is debugged and calibrated. The laser marking device is installed on the mounting bracket 10 through the connecting member 11. The drum surface assembly 23 on the debugging device 20 is used to simulate the real working conditions, and the scale 231 on the drum surface assembly 23 visualizes and scales the optical path of the laser lamp. Thus, it is convenient for the operator to check and adjust the orientation of the laser lamp under various working conditions, so that the orientation of the laser lamp is calibrated. The working condition simulation can be realized by driving the drum surface assembly 23 with the transverse movement mechanism 21 and the expansion and contraction mechanism 22: the transverse movement mechanism 21 drives the drum surface assembly 23 to move horizontally, so that the predetermined scale on the scale 231 corresponds to the central laser lamp, and the debugging reference can be set; then, the expansion and contraction mechanism 22 drives the drum surface assembly 23 to move longitudinally, changing the distance between the scale 231 and the laser marking device, so that the scales of each laser lamp on the three scales 231 remain unchanged and are not affected by the distance of the drum surface assembly 23, thereby improving the orientation accuracy of the laser lamp.

[0047] Refer to Figure 2 , in a preferred embodiment, the drum surface assembly 23 is provided with a plurality of arc-shaped members 232, and each of the arc-shaped members 232 is coaxially arranged and forms an arc-shaped drum surface. Each scale 231 is parallel to the central axis of the drum surface assembly 23 and is horizontally connected to each arc-shaped member 232. The drum surface assembly 23 simulates the mechanical drum of a tire building machine, but does not restore the simulation 100% and does not need to rotate. The plurality of arc-shaped members 232 are coaxially arranged to form a partial cylindrical surface, and compared with the real mechanical drum, the axial length of the drum surface is increased, which is suitable for simulating tires of various diameters. In this embodiment, the arc-shaped members 232 are arranged in 11 rows side by side. One scale 231 is connected to each arc-shaped member 232, and each arc-shaped member 232 has a connection point, so that the stability of the scale 231 is greatly improved. When the drum surface assembly 23 moves, the scale 231 will not vibrate and affect the accuracy of the scale. Specifically, each arc-shaped member 232 is provided with three grooves, and the grooves are adapted to the width of the arc-shaped member 232. The arc-shaped member 232 is positioned in the groove through a fastener such as a screw.

[0048] Refer to Figure 3 and Figure 4, in another preferred embodiment, the debugging device 20 includes a chassis 24. The chassis 24 is provided with at least one set of guide rails 241. The transverse movement mechanism 21 includes a first driving member 211 and a transverse movement frame 212. The first driving member 211 is disposed on the chassis 24. The transverse movement frame 212 is in transmission connection with the first driving member 211. When the first driving member 211 operates, it drives the transverse movement frame 212 to slide on the guide rails 241. The chassis 24 is mainly used to connect to the ground and its position is determined. Specifically, the first driving member 211 is a trapezoidal lead screw. One end of the trapezoidal lead screw is arranged on the chassis 24 through a bearing block 2111. A nut 2112 is provided on the trapezoidal lead screw to achieve transmission. The bottom surface of the transverse movement frame 212 is fixedly connected to the nut 2112. Rotating the handwheel of the trapezoidal lead screw makes the trapezoidal lead screw rotate, and the nut 2112 drives the transverse movement frame 212 to move. The lead screw transmission has the advantages of high adjustment accuracy and strong stability, and is more suitable for the precise debugging device 20 compared with gear transmission, belt transmission, and chain transmission. A stop device 2113 is also provided on the bearing block 2111. When the transverse movement mechanism 21 moves to the in-place position, the stop device 2113 is used to lock the drum surface assembly 23 at this position. The stop device 2113 is manually operated and has a relatively high locking reliability.

[0049] Refer to Figure 5 , in another preferred embodiment, the transverse movement mechanism 21 is provided with a guide member 213. The guide member 213 is inclined. The expansion and contraction mechanism 22 includes a second driving member 221 and an expansion and contraction frame 222. The second driving member 221 is disposed on the transverse movement mechanism 21. The expansion and contraction frame 222 is in transmission connection with the second driving member 221. When the second driving member 221 operates, it drives the expansion and contraction frame 222 to slide on the guide member 213, and the drum surface assembly 23 is connected to the expansion and contraction frame 222. Specifically, the structure of the second driving member 221 is substantially the same as the structure of the first driving member 211. The difference lies in the structure of the guide member 213 and the structure of the expansion and contraction frame 222. The guide member 213 is inclined, which is made by imitating the structure of the forming machine. The gantry is generally higher than the mechanical drum. Therefore, the drum surface assembly 23 moves obliquely upward and approaches or moves away from the laser marking device along the guide member 213, which is more in line with the actual working conditions. Since the drum surface assembly 23 has a plurality of arc-shaped members 232 and three scales 231 and has a relatively long dimension, the guide member 213 can be symmetrically arranged as two on both sides of the second driving member 221 to improve the guiding stability. The guide member 213 passes through between the arc-shaped members 232, and the radial movement of the arc-shaped members 232 does not exceed the guide member 213. Since the guide member 213 is inclined, rib plates can be provided to increase the stability. It should be noted that if the second driving member 221 uses a lead screw, then the lead screw is also inclined, and collisions between the lead screw and the transverse movement frame 212 should be avoided.

[0050] In another preferred embodiment, each scale 231 is provided with a photosensitive sensor or a red marker at a preset integer position. The photosensitive sensor is made of photosensitive semiconductor material and is used to convert optical signals into electrical signals. During the debugging process, it is necessary to first set the position of the laser lamp as the central beacon and align the optical path of the scale 231 with that of the central laser lamp before the debugging reference is set. On this basis, the debugging of the two side laser lamps makes sense. By using the photosensitive sensor or the red marker, obvious prompts can be given to the staff when the laser reaches the predetermined integer scale, improving the debugging efficiency.

[0051] Referring to Figure 6 , in another preferred embodiment, the connecting member 11 is provided with a connecting portion 111 and a positioning portion 112 adapted to the laser line marker. The connecting portion 111 is detachably connected to the laser line marker. The mounting bracket 10 provides a horizontal mounting structure for the laser line marker. In actual installation, the positioning portion 112 can quickly adapt to the laser line marker, and then the laser line marker is mounted on the mounting bracket 10 by using the connecting portion 111, improving the installation efficiency and progress of the laser line marker. The connecting members 11 are provided in groups, two in a group, and are respectively adapted to and mounted on both ends of the laser line marker. Specifically, the positioning portion 112 is provided with a mechanical stop, which fits with the concave-convex shape of the laser line marker. The connecting portion 111 can be provided with a plurality of long holes, and the laser line marker is fixed at different positions of the long holes by screws, so that the height of the laser line marker is consistent with that of the actual tire forming machine. The connecting portion 111 and the positioning portion 112 are arranged on different sides of the connecting member 11 and do not affect each other. In another preferred embodiment, there are two groups of connecting members 11, which are respectively arranged on both sides of the mounting bracket 10, and two laser line markers can be installed simultaneously for debugging at the same time.

[0052] Referring again to Figure 1 , in another preferred embodiment, the mounting bracket 10 includes a frame body 12 and a cross beam 13. The connecting member 11 is mounted on the cross beam 13, and the height of the cross beam 13 is adjustable and is arranged on the frame body 12. The frame body 12 is used to connect to the ground and support the cross beam 13 to prevent the uneven ground from directly affecting the levelness of the cross beam 13. The installation position between the frame body 12 and the cross beam 13 can be finely adjusted within a certain range to simulate the dimensions and levelness of the gantry on different forming machines. For example, they are connected through long holes, and the bolts can be tightened at appropriate positions in the long holes. After the adjustment of the laser line marker is completed, it can be directly removed from the mounting bracket 10 and installed on the gantry of the forming machine.

[0053] The present invention also provides a debugging method for a laser line marker based on tire forming, including the following steps:

[0054] 1. Install the laser marking device on the connecting piece 11. Turn on the central laser lamp and the laser lamps on both sides of the laser marking device, and adjust the three laser lamps so that their optical paths are all perpendicular to the scale 231. Specifically, before installation, the position of the connecting piece 11 should be carefully adjusted so that after the laser marking device is installed, the guide rail of the laser marking device is parallel to the scale 231, and the parallelism error is minimized.

[0055] 2. Adjust each laser lamp so that the scales of the optical paths of the same laser lamp on the three scales 231 are the same. This can ensure that the optical paths of each laser lamp are parallel to each other. Since the laser marking device has been calibrated at the factory, the orientation of the laser lamp is only fine-tuned within a small angle (such as 2°) at this time.

[0056] 3. Start the cross-movement mechanism 21 to move the drum surface assembly 23 horizontally until the predetermined scale O of the scale 231 is aligned with the optical path of the central laser lamp, and record the scale readings of the optical paths of the three laser lamps corresponding to the scale as M 1 、O、M 2 . The predetermined scale is generally an integer scale. Align the specific integer scale of the drum surface assembly 23 with the optical path of the central laser lamp as the debugging reference, so as to facilitate adjusting the distances between the laser lamps on both sides and the central laser lamp. Recording the scale readings of the optical paths is for the next step.

[0057] 4. Start the expansion and contraction mechanism 22 to move the drum surface assembly 23 longitudinally away from the laser marking device by a predetermined distance S. At this time, the scale readings of the optical paths of the three laser lamps corresponding to the scale are M 11 、O 1 、M 21 , and fine-tune each laser lamp so that O 1 = O, M 11 = M 1 , M 21 = M 2 . Before and after the longitudinal expansion and contraction of the drum surface assembly 23, the scale of the optical path of the same laser lamp on the scale 231 should be the same as the scale of the scale 231 before the drum surface assembly 23 moves. It can be understood that during debugging, the scale 231 moves away from the laser lamp from near to far. If the orientation of the laser lamp is deviated, the farther away from the laser lamp, the greater the deviation, that is, the scale on the scale 231 will shift. Therefore, the farther the scale 231 is, the higher the requirement for the orientation accuracy of the laser lamp. In actual working conditions, the mechanical drum will also have a radial dimension change. Therefore, the moving distance should at least cover the radial change range of the mechanical drum (generally 1200mm - 1500mm). Therefore, when moving to the maximum distance of 1500mm, adjust the laser lamp so that the scale reading of the optical path corresponding to the scale 231 is the same as before moving.

[0058] 5. Start the laser marking device, move the laser lights on both sides horizontally by a standard distance A, and the scale readings corresponding to the optical paths of the laser lights on both sides are N 1 , N 2 , and the moving distance M of the optical paths of the two laser lights 1 N 1 , M 2 N 2 . If M 1 N 1 ≠A or M 2 N 2 ≠A, adjust the guide rail where the laser light is located. After resetting, move the laser lights on both sides again until M 1 N 1 =M 2 N 2 =A. Since the debugging device 20 fully simulates the molding machine, if the horizontal movement scales cannot be kept consistent, it means that the moving trajectory of the laser light is not parallel to the scale 231 (i.e., the axis of the drum surface assembly 23). Then the marking position will also be deviated, and it is necessary to adjust the moving trajectory of the laser light to be completely parallel to the scale 231. And the moving trajectory of the laser light is determined by the guide rail. It is necessary to correct the deviation of the guide rail to ensure that when the laser light moves horizontally by a standard distance A, the optical path on the scale 231 also moves by a standard distance A, so that the marking position of the laser light can be ensured to be accurate.

[0059] In a preferred embodiment, in step 4, after starting the expansion and contraction mechanism 22, the drum surface assembly 23 continues to move longitudinally away from the laser marking device, moves two or more predetermined distances, and correspondingly completes fine-tuning of the laser light two or more times. Specifically, use the expansion and contraction mechanism 22 to move the scale 231 at the 1200 mm and 1500 mm positions, record the light line scale values at the two positions, and adjust the laser light to make the values at the two positions the same to check the accuracy of different detection ranges. This embodiment increases the number of movements of the scale 231, and each movement requires debugging, further enhancing the detection accuracy of the laser light.

[0060] In another preferred embodiment, after starting and adjusting the expansion and contraction mechanism 22, reset the expansion and contraction mechanism 22, and again move the drum surface assembly 23 longitudinally away from the laser marking device to make the optical paths of the same laser light consistent on the scale 231 of the drum surface assembly 23. It is equivalent to resetting the scale 231 and then moving it from near to far, and it can be moved to the farthest detection distance. The optical paths of the same laser light should remain unchanged on the scale 231, so as to ensure the orientation accuracy of the laser light.

[0061] Specifically, in step 5, M 1 N 1 , A, M 2 N 2Relationship: It can be understood that the mounting surface on the crossbeam 13 for installing the laser marking device has been parallel-calibrated with the scale 231 during the initial debugging of the tooling installation. That is, by default, when the laser marking device is installed on the mounting surface of the crossbeam 13 through the connecting member 11, the direction of the linear guide is parallel to the direction of the scale 231. In the previous step, the optical path has been adjusted to be perpendicular to the scale 231, that is, it can be determined that the optical path is also perpendicular to the linear guide at this time. If M 1 N 1 ≠A or M 2 N 2 ≠A, and the orientation of the laser lamp has been accurately adjusted in steps 1-4, then the reason for the problem is that the guide rail of the laser marking device is deviated, and the direction of the guide rail is not parallel to the scale 231. Since the positions of the scale 231 and the central laser lamp have also been calibrated, the position of the middle part of the guide rail where the central laser lamp is located is basically accurate. Then, the deviation of the two ends of the guide rail is larger than that of the middle part of the guide rail, and it is closer to or farther from the scale 231. Then, when the two laser lamps move a standard distance A, the moving distance of the optical path of the laser lamp is M 1 N 1 and M 2 N 2 , it will be larger or smaller than A.

[0062] In another preferred embodiment, if M 1 N 1 ≠A or M 2 N 2 ≠A, adjust one end of the guide rail to make it shift upward, and re-measure the moving distance of the optical path:

[0063] If the error between the moving distance of the optical path and A becomes larger, then adjust this end to make it shift downward;

[0064] If the error between the moving distance of the optical path and A becomes smaller, then continue to adjust this end to make it shift upward until the moving distance of the optical path is the same as A.

[0065] This is because the guide rail is linear, and there are two ends of the guide rail where the laser lamp is located. Adjusting the two ends can most intuitively see the change of the value, and adjusting the other end can also achieve the same effect. The laser marking device has been calibrated before leaving the factory, and the deviation of the guide rail is generally in a very small range, and fine adjustment should be made during adjustment. It should be noted that after adjusting the guide rail of the laser marking device, in order to ensure the accuracy, the debugging and calibration can be restarted from step 2, and the error of the second debugging will be smaller and the debugging will be faster.
