DETAILED DESCRIPTION

[0041] In order to make the purpose, 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 in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. The debugging tooling and debugging method of the laser marking device based on tire molding provided by the present invention not only have higher adjustment accuracy and more standardized debugging process, but also improve debugging efficiency. The present invention is described in detail below in combination with the drawings in the specification and specific implementation methods.

[0042] In order to overcome the problems of low accuracy and low debugging efficiency in the debugging method of the laser marking device in the prior art, refer to Figure 1 and Figure 2 The present invention provides a debugging tool for a laser marking device based on tire molding, including a mounting frame 10 and a debugging device 20. The mounting frame 10 is used to install the laser marking device, and the debugging device 20 scales the optical path position of the laser light to facilitate the adjustment of the direction of the laser light.

[0043] The mounting frame 10 is provided with a connector 11 adapted for horizontal installation of the laser marking device. The mounting frame 10 is designed to imitate the gantry of the tire building machine, and the purpose is to allow the laser marking device to be installed horizontally. Generally, the laser marking device is provided with a central laser lamp and laser lamps on both sides. The central laser lamp does not need to be moved when the building machine is running. It 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 position required by the process.

[0044] The debugging device 20 includes a transverse movement mechanism 21, an expansion and contraction mechanism 22 and a drum head assembly 23 which are connected in sequence. The drum head assembly 23 is provided with a scale 231 for receiving the vertical light path of the laser lamp. The scales 231 are arranged in three numbers 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 line on the drum head assembly 23. Since the laser lamp emits a fan-shaped light path, it can cover the three scales 231. The fan-shaped light path should be perpendicular to the scale, and the 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 inconsistent, the orientation of the laser lamp should be adjusted.

[0045] The transverse movement mechanism 21 moves, driving the expansion and contraction mechanism 22 and the drum head assembly 23 to move transversely; the expansion and contraction mechanism 22 moves, driving the drum head assembly 23 to expand and contract longitudinally. The drum head assembly 23 imitates the mechanical drum design of the tire building machine, and the drum head assembly 23 should maintain a shape with the same curvature 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 head assembly 23 to complete transverse and longitudinal movement, thereby making the drum head assembly 23 highly simulate the movement of the mechanical drum.

[0046] The present invention is used to debug and calibrate the laser light of the laser marking device before the laser marking device is applied to the tire forming machine. The laser marking device is installed on the mounting frame 10 through the connecting member 11, and the drum head assembly 23 on the debugging device 20 is used to simulate the real working condition, and the scale 231 on the drum head assembly 23 visualizes and scales the optical path of the laser light, thereby facilitating the operator to check and adjust the direction of the laser light under various working conditions, so that the direction of the laser light is calibrated. The working condition simulation can be achieved by driving the drum head assembly 23 with the transverse movement mechanism 21 and the expansion and contraction mechanism 22: the transverse movement mechanism 21 drives the drum head assembly 23 to move horizontally, so that the predetermined scale on the scale 231 corresponds to the center laser light, and the debugging benchmark can be set; then the expansion and contraction mechanism 22 is used to drive the drum head assembly 23 to move longitudinally, and the distance between the scale 231 and the laser marking device is changed, so that the scales of each laser light on the three scales 231 remain unchanged, and are not affected by the distance of the drum head assembly 23, thereby improving the direction accuracy of the laser light.

[0047] See also Figure 2In a preferred embodiment, the drum head assembly 23 is provided with a plurality of arc-shaped pieces 232, and each arc-shaped piece 232 is coaxially arranged to form an arc-shaped drum head, and each scale 231 is parallel to the central axis of the drum head assembly 23 and is laterally connected to each arc-shaped piece 232. The drum head assembly 23 simulates the mechanical drum of the tire forming machine, but it is not a 100% restoration simulation and does not need to rotate. The plurality of arc-shaped pieces 232 are coaxially arranged to form a partial cylinder, and the axial length of the drum head is increased compared to the real mechanical drum, which is suitable for simulating tires of various diameters. In this embodiment, the arc-shaped pieces 232 are arranged to be 11 side by side. A scale 231 is connected to each arc-shaped piece 232, and each arc-shaped piece 232 has a connection, so that the stability of the scale 231 is greatly improved, and when the drum head assembly 23 moves, the scale 231 will not vibrate to affect the accuracy of the scale. Specifically, each arc-shaped piece 232 is provided with three grooves, and the grooves are adapted to the width of the arc-shaped piece 232. The arc-shaped member 232 is positioned in the groove by fasteners such as screws.

[0048] See also Figure 3 and Figure 4 In another preferred embodiment, the debugging device 20 includes a base frame 24, and the base frame 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 arranged on the base frame 24. The transverse movement frame 212 is connected to the first driving member 211 by transmission. When the first driving member 211 moves, it drives the transverse movement frame 212 to slide on the guide rail 241. The base frame 24 is mainly used to connect with the ground and determine the position. Specifically, the first driving member 211 is a trapezoidal screw, one end of which is arranged on the base frame 24 through a bearing seat 2111. A nut 2112 is arranged on the trapezoidal screw to realize transmission. The bottom surface of the transverse movement frame 212 is tightly connected to the nut 2112. The hand wheel of the trapezoidal screw is rotated to rotate the trapezoidal screw, and the nut 2112 drives the transverse movement frame 212 to move. The screw drive has the advantages of high adjustment accuracy and strong stability, and is more suitable for accurate debugging of the device 20 than the gear drive, belt drive, and chain drive. A stopper 2113 is also provided on the bearing seat 2111. When the transverse movement mechanism 21 moves into position, the drum head assembly 23 is locked at this position by the stopper 2113. The stopper 2113 is manually operated, and the locking reliability is high.

[0049] See also Figure 5In another preferred embodiment, the transverse movement mechanism 21 is provided with a guide member 213, and the guide member 213 is tilted. 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 arranged on the transverse movement mechanism 21. The expansion and contraction frame 222 is connected to the second driving member 221 by transmission. The second driving member 221 moves, driving the expansion and contraction frame 222 to slide on the guide member 213, and the drum head 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 that of the first driving member 211. The difference is the structure of the guide member 213 and the structure of the expansion and contraction frame 222. The guide member 213 is tilted, which is made in imitation of the structure of the molding machine. The gantry is generally higher than the mechanical drum, so the drum head assembly 23 moves obliquely upward and approaches or moves away from the laser marker along the guide member 213, which is more in line with the actual working conditions. Since the drum head assembly 23 has a plurality of arc-shaped members 232 and three scales 231, and has a relatively long size, the guide members 213 can be symmetrically arranged in two on both sides of the second driving member 221 to improve the guiding stability. The guide member 213 passes 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 arranged at an angle, ribs can be arranged to increase stability. It should be noted that if the second driving member 221 adopts a screw rod, the screw rod is also arranged at an angle, and collision between the screw rod and the transverse 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 materials 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 light as the central beacon and match the scale 231 with the optical path of the central laser light to set the debugging benchmark. On this basis, the debugging of the laser lights on both sides is meaningful. The use of photosensitive sensors or red markers can give the staff an obvious prompt when the laser reaches the predetermined integer scale, thereby improving the debugging efficiency.

[0051] See also Figure 6In another preferred embodiment, the connector 11 is provided with a connector 111 and a positioning portion 112 adapted to the laser marker, and the connector 111 is detachably connected to the laser marker. The mounting frame 10 provides a horizontal mounting structure for the laser marker. In actual installation, the positioning portion 112 can be quickly adapted to the laser marker, and then the laser marker is installed on the mounting frame 10 using the connector 111, thereby improving the installation efficiency and progress of the laser marker. The connectors 11 are arranged in groups, two in a group, and are respectively adapted to be installed at both ends of the laser marker. Specifically, the positioning portion 112 is provided with a mechanical stopper, which matches the concave and convex shape of the laser marker. The connector 111 can be provided with a plurality of long holes, and the laser marker is fixed at different positions of the long holes by screws, so that the height of the laser marker is consistent with the actual tire forming machine. The connector 111 and the positioning portion 112 are arranged on different sides of the connector 11 without affecting each other. In another preferred embodiment, the connecting members 11 are divided into two groups, which are respectively arranged on both sides of the mounting frame 10, so that two laser markers can be installed and debugged at the same time.

[0052] See again Figure 1 In another preferred embodiment, the mounting frame 10 includes a frame body 12 and a crossbeam 13, the connecting member 11 is mounted on the crossbeam 13, and the height of the crossbeam 13 is adjustable on the frame body 12. The frame body 12 is used to connect to the ground and support the crossbeam 13 to prevent the uneven ground from directly affecting the horizontality of the crossbeam 13. The installation position between the frame body 12 and the crossbeam 13 can be fine-tuned within a certain range to simulate the size and horizontality of the gantries on different molding machines. For example, the connection is made through a long hole, and the bolts can be tightened at the appropriate position of the long hole. After the laser marker is adjusted, it can be directly removed from the mounting frame 10 and installed on the gantry of the molding machine.

[0053] The present invention also provides a debugging method of a laser marking device based on tire molding, comprising the following steps:

[0054] 1. Install the laser marker on the connecting piece 11, turn on the central laser light and the laser lights on both sides of the laser marker, and adjust the three laser lights so that their optical paths are all vertical to the ruler 231. Specifically, before installation, the position of the connecting piece 11 should be carefully adjusted so that after the laser marker is installed, the guide rail of the laser marker is parallel to the ruler 231, and the parallelism error is minimized.

[0055] 2. Adjust each laser light so that the light path of the same laser light has the same scale on the three scales 231. This ensures that the light paths of each laser light are parallel to each other. Since the laser marker has been calibrated at the factory, the direction of the laser light is only fine-tuned within a small angle (such as 2°).

[0056] 3. Start the transverse movement mechanism 21 to move the drum head assembly 23 horizontally until the predetermined scale O of the ruler 231 is aligned with the optical path of the center laser light, and record the scale scales corresponding to the optical paths of the three laser lights as M1, O, and M2. The predetermined scale is generally an integer scale. Align the specific integer scale of the drum head assembly 23 with the optical path of the center laser light as a debugging reference, so as to facilitate the adjustment of the distance between the laser lights on both sides and the center laser light. Recording the scale scale of the optical path is to prepare for the next step.

[0057] 4. Start the expansion and contraction mechanism 22 to move the drum assembly 23 away from the laser marker longitudinally by a predetermined distance S. At this time, the scale scales corresponding to the optical paths of the three laser lights are M and 11 、O1、M 21 , fine-tune each laser light so that O1=O,M 11 =M1,M 21 =M2. Before and after the longitudinal extension and retraction of the drum head assembly 23, the optical path of the same laser lamp on the scale 231 should be consistent with the scale 231 before the drum head 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 direction 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 be offset. 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 produce radial dimensional changes, so the moving distance should at least cover the radial variation 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 231 corresponding to the optical path is consistent with that before the movement.

[0058] 5. Start the laser marking device to make the laser lights on both sides move horizontally by a standard distance A. The scale scales corresponding to the optical paths of the laser lights on both sides are N1 and N2 respectively. The optical paths of the two laser lights move by distances M1N1 and M2N2. If M1N1≠A or M2N2≠A, adjust the guide rail where the laser lights are located, reset and move the laser lights on both sides again until M1N1=M2N2=A. Since the debugging device 20 completely simulates the molding machine, if the horizontal movement scale cannot be kept consistent, it means that the moving trajectory of the laser light is not parallel to the scale 231 (i.e., the axial direction of the drum head assembly 23), then the marking position will also deviate, and the moving trajectory of the laser light needs to be adjusted to be completely parallel to the scale 231. The moving trajectory of the laser light is determined by the guide rail, and the guide rail needs to be corrected 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 guaranteed to be accurate.

[0059] In a preferred embodiment, in step 4, after the expansion and contraction mechanism 22 is started, the drum assembly 23 continues to move longitudinally away from the laser marker, moves more than two predetermined distances, and correspondingly completes more than two fine adjustments of the laser light. Specifically, the expansion and contraction mechanism 22 is used to move the ruler 231 at the positions of 1200mm and 1500mm, and the light line scale values ​​at the two positions are recorded. The laser light is adjusted so that the values ​​at the two positions are the same, and the accuracy of different detection ranges is tested. This embodiment increases the number of movements of the ruler 231, and each movement requires debugging, which further enhances the detection accuracy of the laser light.

[0060] In another preferred embodiment, after the expansion and contraction mechanism 22 is started and adjusted, the expansion and contraction mechanism 22 is reset, and the drum assembly 23 is moved longitudinally away from the laser marker again, so that the optical path of the same laser lamp is consistent at the scale of the ruler 231. This is equivalent to resetting the ruler 231 and moving it from near to far, and it can be moved to the farthest detection distance. The optical path of the same laser lamp should remain unchanged at the scale of the ruler 231, thereby ensuring the orientation accuracy of the laser lamp.

[0061] Specifically, in step 5, the relationship between M1N1, A, and M2N2 is as follows: It can be understood that the mounting surface on the beam 13 for mounting the laser marker has been parallelly calibrated with the ruler 231 during the initial debugging of the tooling installation, that is, when the laser marker is installed on the mounting surface of the beam 13 through the connector 11, the direction of the linear guide is parallel to the direction of the ruler 231. The aforementioned steps have adjusted the optical path to be perpendicular to the ruler 231, that is, it can be determined that the optical path is also perpendicular to the linear guide at this time. If M1N1≠A or M2N2≠A, steps 1-4 have adjusted the direction of the laser light accurately, then the cause of the problem is that the guide rail of the laser marker has a deviation, and the direction of the guide rail is not parallel to the ruler 231. Since the positions of the ruler 231 and the center laser light have also been calibrated, the center laser light is located in the middle of the guide rail. The deviation at both ends of the guide rail is larger than that in the middle of the guide rail, and is closer or farther from the ruler 231. Then, when the two laser lights move a standard distance A, the distances M1N1 and M2N2 of the optical paths of the laser lights moving will be larger or smaller than A.

[0062] In another preferred embodiment, if M1N1≠A or M2N2≠A, one end of the guide rail is adjusted to be offset upward, and the optical path movement distance is remeasured:

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

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

[0065] This is because the guide rail is a straight line, and the laser light has two ends. Adjusting the two ends can most intuitively see the change in the value, and adjusting the other end can also achieve the same effect. The laser marking device is calibrated at the factory, and the guide rail deviation is generally in a very small range, so it should be fine-tuned during adjustment. It should be noted that after adjusting the guide rail of the laser marking device, in order to ensure accuracy, you can re-debug and calibrate from step 2. The error of the second debugging will be smaller and the debugging will be faster.

[0066] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
