Description

Technical Field

[0001] This invention relates to the field of laser marking technology, specifically to an intelligent laser marking device. Background Technology

[0002] Laser marking technology achieves graphic printing through a laser marking machine. Its basic principle involves a laser generator producing a high-energy continuous laser beam. When the laser acts on the substrate, atoms in their ground state transition to a higher energy state. These higher-energy atoms are unstable and quickly return to their ground state. Upon returning, they release additional energy in the form of photons or quanta, which is then converted into heat energy, causing the surface material to melt or even vaporize instantly, thus forming the graphic mark.

[0003] For example, patent CN106514003B, published on March 15, 2019, discloses a laser marking machine, relating to the field of laser application technology. It includes a laser marking device, a marking transmission device, a control device, and an operation display device. The laser marking machine is characterized by using an integrated cabinet, with the laser marking device and the marking transmission device fixedly connected to the integrated cabinet; the marking transmission device has a workpiece fixing part, and the marking head of the laser marking device corresponds to the workpiece fixing part; the marking transmission device includes a linear transmission component and a rotary transmission component, the transmission components being interconnected; and the control device controls the transmission components to move the workpiece. The control device is located inside the integrated cabinet and / or rotates; the workpiece fixing part is connected to the external workpiece clamping device through a connecting structure, and the workpiece is clamped by the clamping device; the linear transmission assembly includes a horizontal transmission assembly for horizontal movement of the workpiece and a lifting transmission assembly for vertical movement of the workpiece; the rotary transmission assembly includes a fourth transmission assembly and a fifth transmission assembly, and the two transmission shafts of the fourth transmission assembly and the fifth transmission assembly are perpendicular to each other; the rotating shaft of the fourth transmission assembly is connected to the first workpiece fixing part, so that the workpiece rotates when placed horizontally left and right; the rotating shaft of the fifth transmission assembly is connected to the second workpiece fixing part, so that the workpiece rotates when placed horizontally front and back.

[0004] When marking existing workpieces, only one side can be marked. When marking the other side, i.e. the adjacent side, is required, the workpiece needs to be adjusted manually, resulting in low work efficiency. Summary of the Invention

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] In the description of this invention, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," and "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] like Figures 1-11 As shown in the figure, an intelligent laser marking device provided by an embodiment of the present invention includes a laser generator 1 and a support plate 2. The support plate 2 is located below the laser generator 1, and a workpiece 5 is horizontally arranged on the support plate 2. The device also includes a driving mechanism 3 and an adjusting mechanism 4. The driving mechanism 3 is used to drive the support plate 2 to move horizontally, and the adjusting mechanism 4 is used to drive the support plate 2 and the workpiece 5 to rotate when the support plate 2 moves horizontally.

[0034] Specifically, the laser generator 1 is mounted above the support plate 2. The laser generator 1 and its control system are existing technologies and will not be described in detail. Both the drive mechanism 3 and the support plate 2 are mounted on the worktable. The drive mechanism 3 can be a linear drive device such as a cylinder or an electric telescopic rod. Two sets of drive mechanisms 3 are installed. One set is connected to the support plate 2 to drive its horizontal movement, and the other set is connected to the laser generator 1 (not shown) to drive its horizontal movement along the X and Y axes. The workpiece 5 is placed horizontally on the support plate 2. The workpiece 5 is generally made of metal. Electromagnetic blocks or permanent magnet blocks are installed inside the support plate 2, using their magnetic properties to attract and fix the workpiece 5 to the support plate 2. Therefore, the movement of the support plate 2 driven by the drive mechanism 3 will cause the workpiece 5 to move synchronously. This allows for the adjustment of the workpiece 5's displacement. Obviously, other workpiece 5 clamping methods can also be used, and workpiece clamping is existing technology, so it will not be elaborated. The adjustment mechanism 4 can be a rotary drive mechanism such as a motor or rotary cylinder. The rotary drive mechanism synchronously receives the drive from the drive mechanism 3. At the same time, the output shaft of the rotary drive mechanism is connected to the support plate 2 to realize the rotation adjustment of the workpiece 5. In actual use, the operator first fixes the workpiece 5 on the support plate 2, and then the drive mechanism 3 drives the support plate 2 to move, and drives the workpiece 5 to move synchronously to directly below the laser generator 1. The laser emitted by the laser generator 1 is used to mark the surface of the workpiece 5. At the same time, the adjustment mechanism 4 can also drive the support plate 2 and the workpiece 5 to rotate, adjusting the marking surface of the workpiece 5. The setting of the adjustment mechanism 4 avoids the traditional manual adjustment method and improves the processing efficiency of the workpiece 5.

[0035] Furthermore, the drive mechanism 3 includes a first drive component 31 and a second drive component 32, with the support plate 2 located between the first drive component 31 and the second drive component 32.

[0036] Specifically, both the first drive assembly 31 and the second drive assembly 32 are lead screw transmission mechanisms. The two sets of lead screws in the first drive assembly 31 and the second drive assembly 32 are parallel to each other and are located on the same plane. In actual use, the two sets of lead screws have multiple motion modes. They can rotate in the same direction and at the same speed, or one of them can stop while the other continues to move, thereby driving the support plate 2 to have different motion forms on the worktable.

[0037] Furthermore, in one mode, the adjustment mechanism 4 includes a first adjustment component 41, which is used to drive the support plate 2 to rotate horizontally when the first drive component 31 is paused and the second drive component 32 is activated.

[0038] Specifically, the first adjusting component 41 includes a first slider 411 and a first connecting block 412. The first slider 411 is threadedly connected to the lead screw in the first driving component 31. The first connecting block 412 is fixedly installed on the top of the first slider 411. A connecting shaft 21 is installed on the bottom of the support plate 2. The support plate 2 is sleeved on the connecting shaft 21. One end of the connecting shaft 21 is connected to the first connecting block 412, and the other end is connected to the second driving component 32. A groove 413 is provided on the side of the first connecting block 412 near the connecting shaft 21. The groove 413 contains a sliding groove 413. A first guide block 414 is installed, which forms a sliding guide fit with the slide groove 413. One end of the connecting shaft 21 passes through the first guide block 414 and extends into the first connecting block 412. A friction wheel 416 is installed at the end extending into the first connecting block 412. A friction plate 417 is installed inside the first connecting block 412. The friction wheel 416 and the friction plate 417 are connected by friction transmission. The connecting shaft 21 is rotatably connected to the first guide block 414. In actual use, the workpiece 5 is initially arranged horizontally on the support plate 2, such as... Figure 3 As shown, workpiece 5 has a first surface 51, a second surface 52, and a third surface 53 that are perpendicular or substantially perpendicular to each other. Figure 3 For ease of understanding, it is simplified to a cuboid. However, those skilled in the art will understand that as long as the overall shape of the workpiece has three basically mutually perpendicular surfaces and there are no protruding structures that prevent it from being flipped, it is applicable to this application (it does not necessarily have to be a cuboid). In the initial state, i.e., the first state, the first surface 51 of the workpiece 5 faces the laser generator 1. After the first surface 51, i.e. the top surface, of the workpiece 5 is marked, when the second surface 52 needs to be marked with a laser, the support plate 2 needs to be adjusted to move the workpiece 5 from the first state to the second state. The adjustment process is the first stroke, as detailed below:

[0039] The first stroke: This refers to the passive rotation caused by the translation of the connecting shaft 21, which is the process of the workpiece adjusting from the first state to the second state. When the first drive assembly 31 pauses, the first slider 411 stops moving synchronously, but the second drive mechanism 3 continues to move horizontally, thereby driving the connecting shaft 21 and the support plate 2 to continue moving horizontally. At this time, the first connecting block 412 is stationary. Thus, the horizontal movement of the connecting shaft 21 drives the first guide block 414 to slide horizontally in the groove 413 of the first connecting block 412. At this time, the connecting shaft 21 drives the friction wheel 416 to move synchronously and roll on the friction plate 417 during the movement. Since the friction plate 417 is stationary, the friction wheel 416 and the friction plate 417 are in contact with each other. There is a certain friction between the rubbing plates 417, so the horizontal movement of the friction wheel 416 on the friction plate 417 will drive its own rotation, and synchronously drive the connecting shaft 21 to rotate. The rotation of the connecting shaft 21 drives the support plate 2 and the workpiece 5 to rotate synchronously. After the rotation is adjusted, the side of the workpiece 5, i.e. the second side 52, rotates to the top and corresponds to the laser generator 1, reaching the second state of the workpiece 5. The second state is the state after the connecting shaft rotates and drives the workpiece to rotate. After adjustment, the first drive component 31 and the second drive component 32 start synchronously and drive the connecting shaft 21 and the support plate 2 to move horizontally again, so that the workpiece 5 can be moved to the second state directly below the laser generator 1, thereby realizing the marking of the side of the workpiece 5.

[0040] Furthermore, in another mode, the adjustment mechanism 4 includes a second adjustment component 42, and the first adjustment component 41 is used to drive the support plate 2 to rotate into an inclined state when the first drive component 31 is activated and the second drive component 32 is inactive.

[0041] Specifically, the second adjustment component 42 includes a second slider 421 and a second connecting block 422. The second slider 421 is threadedly connected to the lead screw in the second drive component 32. A guide groove 423 is provided on the top of the second slider 421. The cross section of the guide groove 423 has an inclined guide surface. A second guide block 424 is installed on the bottom of the second connecting block 422. The second guide block 424 and the guide groove 423 form a sliding guide fit. The two ends of the connecting shaft 21 are movably connected to the first connecting block 412 and the second connecting block 422, respectively.

[0042] Let the end of the connecting shaft 21 connected to the first connecting block 412 be called the first end, and the other end connected to the second connecting block 422 be called the second end. A friction wheel 416 is arranged on the end face of the first end. A ball hinge 415 is also installed on the first end. A movable groove is opened inside the first guide block 414, and the ball hinge 415 is located in the movable groove. A telescopic shaft 25 is also installed on the first end, and a spring is installed inside the telescopic shaft 25. The end face of the second end is fixedly connected to the second connecting block 422. Figure 9 and Figure 11As shown, the second end is provided with two sets of hinge shafts 425. One set of hinge shafts 425 is used to realize the rotation of the connecting shaft 21, that is, the rotation in the first stroke. The other set of hinge shafts 425 is used to support the tilting state of the connecting shaft 21 in the second stroke. The hinge shafts 425 have an insert-type structure, that is, the hinge shafts 425 are inserted into the groove opened on the second end of the connecting shaft. When the second end rises, the connecting shaft 21 tilts, and the second end of the connecting shaft 21 swings up and down on the surface of the second connecting block 422 through the other set of hinge shafts 425. Further explanation is needed. Yes, when the second drive assembly 32 drives the connecting shaft 21 to move horizontally, the other set of hinge shafts 425 will remain stationary. The first guide block 414 and the connecting shaft 21 move horizontally instead of swinging horizontally. The ball hinge 415 will not rotate within the first guide block 414, but will remain in a relatively stationary state. In actual use, when it is necessary to perform oblique marking on the first surface 51 of the workpiece 5, it is necessary to adjust the tilt of the workpiece 5 to adjust it from the initial state to the tilted state. The tilted state is the third state. The second stroke of the adjustment is as follows:

[0043] Second stroke: When the second drive assembly 32 pauses, the second slider 421 stops moving, while the first drive mechanism 3 drives the workpiece 5 and the support plate 2 to continue moving horizontally via the first guide block 414 and the connecting shaft 21. The continued movement of the connecting shaft 21 drives the second connecting block 422 to move in the guide groove 423. At this time, the second guide block 424 slides on the inclined guide surface of the guide groove 423. The guide surface drives the second guide block 424 to rise during the horizontal movement. The rise of the second guide block 424 drives the second connecting block 422 to rise synchronously. The rise of the second connecting block 422 drives the second end of the connecting shaft 21 to rise. The ball hinge 415 on the first end rotates in the movable groove, that is, the part of the first end located inside 412 swings downward, while the part located outside 412 swings upward. The telescopic shaft 25 is forced to stretch, and the connecting shaft 21 rotates from the initial horizontal state to the inclined state. The support plate 2 and the workpiece 5 also rotate to the inclined state with the rotation of the connecting shaft 21. At this time, the workpiece 5 reaches the third state. In the third state, the connecting shaft 21 swings upward around the center of the ball hinge 415, and the second end of the connecting shaft 21 rises. At this time, the connecting shaft 21 tilts, causing the support plate 2 and the workpiece 5 to tilt. The first drive assembly 31 and the second drive assembly 32 start synchronously again, so that the workpiece 5 can be moved to the direct below the laser generator 1. At this time, the first surface 51 of the workpiece 5 rotates from the initial horizontal plane to an inclined surface. The laser generator 1 can then perform laser marking on the inclined first surface 51 to achieve oblique marking of the workpiece 5. At the same time, the rotation of the workpiece 5 will also rotate the third surface 53 adjacent to the first surface 51 from the vertical plane to an inclined surface, that is, the third surface 53 also faces the laser generator 1. At this time, the laser generator 1 can extend the pattern to be marked from the first surface 51 to the third surface 53 to achieve double-sided marking of the workpiece 5. In the metal product workpiece 5 processing industry, this kind of double-sided marking can print the necessary information and markings on two adjacent surfaces at the same time, which can improve the readability and convenience of the workpiece 5 marking.

[0044] It should be added that, such as Figure 1 As shown in the figure, the dashed lines represent two directions of rotation. The direction on the left is the rotation direction of the connecting shaft 21 and the workpiece 5 of the support plate 2 during the first stroke, that is, the rotation of the connecting shaft 21. The direction on the right is the rotation direction of the connecting shaft 21 and the workpiece 5 of the support plate 2 during the second stroke, that is, the upward rotation of the second end of the connecting shaft 21.

[0045] Furthermore, the friction plate 417 has an arc-shaped plate structure.

[0046] Specifically, such as Figure 7As shown, the friction plate 417 has an arc-shaped plate structure. The side of the friction plate 417 that contacts the friction wheel 416 is arc-shaped. In the second stroke, the second end of the connecting shaft 21 rotates upward and the first end rotates downward. The ball hinge 415 rotates in the movable groove and drives the friction wheel 416 to rotate downward. The friction wheel 416 revolves around the center of the ball hinge 415. The friction wheel 416 slides on the friction surface of the friction plate 417. At this time, the friction wheel 416 is in a stationary state. After the friction wheel 416 revolves, it can also maintain the friction transmission relationship between the friction wheel 416 and the friction plate 417. That is, in the second stroke, the friction wheel 416 can always maintain the friction transmission with the friction plate 417 after rotating.

[0047] After the second stroke, that is, after the workpiece 5 rotates to the third state, the workpiece 5 can be rotated from the third state to the fourth state through the third stroke. The fourth state is the state after the workpiece 5 is rotated by the rotation of the connecting shaft 21 when it is in the third state. The setting of the fourth state can realize the replacement of the marking surface when the workpiece 5 is marked obliquely or double-sided. The process of the third stroke is the same as that of the first stroke, which will not be described again here. The friction plate 417 has an arc-shaped plate structure that can meet the rotation of the friction wheel 416 in the third stroke and realize the rotation of the connecting shaft 21 after the second stroke.

[0048] Furthermore, the adjustment mechanism 4 also includes a limiting component 43, which is used to limit the sliding of the first guide block 414 in the slide groove 413 and the second guide block 424 in the guide groove 423.

[0049] Specifically, multiple sets of limiting components 43 are arranged and installed on the first guide block 414 and the second guide block 424 respectively. In the first stroke and the third stroke, the second slider 421 and the second connecting block 422 drive the connecting shaft 21 to move. In order to prevent the second connecting block 422 from sliding in the second slider 421, the limiting components 43 limit the second guide block 424 at the bottom of the second connecting block 422 in the guide groove 423. At this time, the second guide block 424 is in a locked state and will not slide in the guide groove 423, so that the second slider 421 can drive the second connecting block 422 to move synchronously. In the second stroke, the locked state of the second guide block 424 can be released.

[0050] Similarly, in the second stroke, the first slider 411 drives the connecting shaft 21 to move through the first guide block 414. In order to prevent the first guide block 414 from sliding in the slide groove 413, the first guide block 414 is limited in the slide groove 413 by the limiting component 43. At this time, the first guide block 414 is in a locked state and will not slide in the slide groove 413, so that the first slider 411 can drive the first guide block 414 to move synchronously. The first guide block 414 will not slide in the slide groove. In the first stroke and the third stroke, the locking state of the first guide block 414 can be released.

[0051] Furthermore, the limiting component 43 includes an electromagnetic block 431, a spring 432, and a locking block 433. The first guide block 414 and the second guide block 424 are both provided with receiving grooves. The electromagnetic block 431, the spring 432, and the locking block 433 are all arranged in the receiving grooves. The electromagnetic block 431 is fixedly connected to the groove wall of the receiving groove. The two ends of the spring 432 are respectively connected to the electromagnetic block 431 and the locking block 433. The locking block 433 and the receiving groove form a sliding guide engagement. The groove walls of the sliding groove 413 and the guide groove 423 are both provided with locking slots 434. The locking slots 434 and the locking block 433 form a limiting abutment engagement.

[0052] Specifically, the locking block 433 is made of metal, and the walls of both the sliding groove 413 and the guide groove 423 have multiple sets of locking slots 434. These multiple sets of locking slots 434 are adapted to lock the first guide block 414 and the second guide block 424 before and after movement. During the first and third strokes, the second guide block 424 is in a locked state. Therefore, after the second guide block 424 moves, the locking slot 434 connects with the receiving groove. After the electromagnetic block 431 is de-energized, it loses its restriction on the locking block 433, and the spring 432 drives the locking block 433 to extend. When inserted into the slot 434, the second guide block 424 is confined within the guide groove 423 under the engagement of the locking block 433, achieving a locked state. Meanwhile, in the first guide block 414, the electromagnetic block 431 is energized, and the electromagnetic block 431 draws the locking block 433 into the receiving groove, so the first guide block 414 can slide within the slide groove 413. Similarly, in the second stroke, the first guide block 414 is locked, and the second guide block 424 is unlocked. The above steps can be repeated.

[0053] It should be noted that the first guide block 414 has a cross-shaped structure to prevent it from falling out of the slide groove 413. The bottom of the second guide block 424 is also equipped with a T-shaped limiting block, and the guide groove 423 is also provided with a corresponding groove to prevent the second guide block 424 from falling out of the guide groove 423.

[0054] Furthermore, the support plate 2 is slidably connected to the connecting shaft 21.

[0055] Specifically, in the second stroke, the connection between the second end and the second connecting block 422 rises, while the height of the first end and the first connecting block 412 remains unchanged. Therefore, the connecting shaft 21 and the workpiece 5 rotate from a horizontal state to an inclined state. At this time, the overall length of the connecting shaft 21 increases, and the telescopic shaft 25 is stretched. Because the telescopic shaft 25 is located on the first end, in the second stroke, the workpiece 5 and the support plate 2 will deviate to one side of the second end, causing the workpiece 5 in the third state to deviate from directly below it, thus affecting the position of the pattern marking on the workpiece 5. To solve this technical problem, a transverse groove 22 is provided on the outer wall of the connecting shaft 21, and a hole is provided inside the support plate 2. The connecting shaft 21 passes through the support plate 2 through a hole. A protrusion 23 is installed on the wall of the hole. The protrusion 23 is located in the transverse groove 22 and forms a sliding guide fit with the transverse groove 22. Since the workpiece 5 is made of metal and has a certain weight, after the connecting shaft 21 and the workpiece 5 rotate from the horizontal state to the inclined state, under the influence of the gravity of the workpiece 5, i.e. the support plate 2, the support plate 2 will slide from the high point of the connecting shaft 21. The protrusion 23 slides in the transverse groove 22, that is, slides to one side of the first end. The position of the workpiece 5 in the third state is adjusted by the sliding of the support plate 2, so that the workpiece 5 can be located directly below the workpiece 5, avoiding the problem of inaccurate pattern marking caused by the position deviation of the workpiece 5.

[0056] Furthermore, a stop 24 is also installed on the connecting shaft 21.

[0057] Specifically, the stop 24 is installed at the first end of the connecting shaft 21 and is located on the side of the telescopic shaft 25 away from the first guide block 414. In actual use, the stop 24 limits the sliding distance of the support plate 2 to avoid the problem of excessive sliding length of the support plate 2.

[0058] Furthermore, the adjustment mechanism 4 also includes a third adjustment component 44, where the stop block 24 and the transverse groove 22 form a sliding guide fit, and the third adjustment component 44 is used to adjust the position of the stop block 24 on the connecting shaft 21.

[0059] Specifically, the stop block 24 has a circular structure, and the inner wall of the stop block 24 is also equipped with a protrusion 23. The protrusion 23 also extends into the transverse groove 22 and forms a sliding guide fit with the transverse groove 22. The third adjustment component 44 includes a rotating ring 441 and a connecting rod 442. The rotating ring 441 is sleeved on the outer wall of the stop block 24 and rotatably connected to the connecting rod 442. The two ends of the connecting rod 442 are rotatably connected to the first guide block 414 and the rotating ring 441, respectively.

[0060] In the initial state and during the second stroke, the stop block 24 is always in contact with the side of the support plate 2 near the first end. During the second stroke, the connecting shaft 21 gradually rotates and tilts, and the stop block 24 also rotates synchronously with the connecting shaft 21. At this time, the distance between the bottom of the stop block 24 and the second slider 421 gradually increases. Under the connection of the connecting rod 442, the stop block 24 is pulled and forced to slide on the transverse groove 22. When the stop block 24 slides, the support plate 2 loses the resistance of the stop block 24 and, under the influence of gravity, also slides synchronously on the connecting shaft 21 with the stop block 24 until the connecting shaft 21 stops rotating. The stop block 24 and the support plate 2 stop moving at the same time. By sliding the stop block 24 on the connecting shaft 21, the support plate 2 can adapt to different tilt angles of the connecting shaft 21 and make different displacement adjustments. Similarly, when the connecting shaft 21 is reset, the connecting rod 442 pushes the stop block 24 to reset and moves it, and drives the support plate 2 to reset.

[0061] It should be noted that the rotation of the rotating ring 441 ensures that the connecting rod 442 remains in its original position when the stop block 24 rotates with the connecting shaft 21 during the first stroke.

[0062] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
