Technical Field

[0001] The present application relates to the technical field of engraving machines, and in particular to a complete multi-axis engraving system. Background Art

[0002] Laser engraving machine is a CNC equipment that uses high-energy density laser beam to perform non-contact processing on the surface of materials. Laser engraving technology is suitable for processing a variety of materials such as metal, plastic, wood, ceramics, etc. due to its high precision and non-contact processing characteristics.

[0003] Existing laser engraving systems are mainly divided into two categories: one is a two-axis (XY) engraving machine based on a mechanical motion frame, which drives the laser head to perform plane engraving through a physical slide rail; the other is a two-axis engraving machine using optical galvanometer technology, which uses a rotating reflector to achieve rapid deflection of the light beam in the XY direction.

[0004] Regarding the above-mentioned related technologies, the format of the optical galvanometer is small, and it is difficult to process large-scale engraving objects; and the frame-type laser engraving machine can generally only be used for flat engraving, and it is difficult to perform three-dimensional engraving.

When the y-axis slide rail rotates to be parallel to the x-axis slide rail, the two universal wheels slide to the two ends of the x-axis slide rail.

[0007] By adopting the above technical solution, the whole multi-axis engraving system can realize precise engraving operations in three-dimensional space. Through the cooperation of the x-axis slide rail, y-axis slide rail and z-axis slide rail, combined with the up and down sliding setting of the laser head, the precise positioning of the workpiece in three-dimensional space is realized, overcoming the limitation that the traditional plane engraving machine can only perform two-dimensional processing, and through the cooperation of the x-axis slide rail and the y-axis slide rail, the movement range in two-dimensional space is greatly increased, and the adaptability of engraving is improved.

The y-axis slide rail can be rotated to a state parallel to the x-axis slide rail, which can reduce the volume and facilitate storage. At the same time, a universal wheel is set, which can facilitate the rotation of the y-axis slide rail and support the y-axis slide rail to improve the stability of the equipment.

Specifically, the design of the first connecting shaft allows the y-axis slide to rotate around it, so as to facilitate the folding of the x-axis slide and the y-axis slide; and the setting of the fixing part can lock the y-axis slide firmly in this position through the handle and the fixing rod with external threads when the y-axis slide is adjusted to be perpendicular to the x-axis slide, that is, in the working state, to prevent it from accidentally rotating, thereby improving the engraving accuracy and operation stability.

[0014] Optionally, it also includes a support assembly for supporting the storage table, the support assembly including a first support rod, a second support rod, a positioning rod and a first limit piece, the length direction of the second motor output shaft is parallel to the length direction of the y-axis slide rail, and a positioning groove is opened on the side wall of the x-axis slide rail along its own length direction, one end of the positioning rod is arranged on the side wall of the first support rod, and the other end of the positioning rod is slidably inserted in the positioning groove, the lower end of the second support rod is slidably inserted in the first support rod, and the upper end of the second support rod is rotatably connected to the storage table, and the first limit piece can limit the second support rod from sliding up and down in the first support rod.

Specifically, the design of the support assembly enables the storage table to maintain good stability in different processing positions. In particular, when the storage table is flipped, the cooperation of the first support rod and the second support rod can effectively disperse the load and avoid structural instability caused by the center of gravity shift. At the same time, the sliding plug-in structure of the positioning rod and the positioning groove, combined with the limiting function of the first limiting member on the second support rod, not only improves the flexibility of the support system, but also ensures the precise positioning of the storage table in any processing posture, thereby providing a more reliable processing platform for laser engraving.

[0016] Optionally, a first limiting hole is provided on the side wall of the first support rod, and a plurality of second limiting holes are provided on the side wall of the second support rod at intervals along the vertical direction. The first limiting member includes a first cylinder, a connecting rod and a first limiting rod. The first cylinder is provided on the positioning seat, and the first limiting rod is connected to the telescopic shaft of the first cylinder through the connecting rod. The first cylinder can drive the first limiting rod to pass through the first limiting hole and the second limiting hole in sequence. The first limiting hole and the second limiting hole are both waist-shaped holes, and the extension direction is parallel to the length direction of the x-axis slide rail.

[0017] By adopting the above technical solution, the first cylinder can drive the first limiting rod to pass through the first limiting hole and the second limiting hole in sequence, thereby realizing accurate locking of the upper and lower sliding positions of the second support rod in the first support rod.

[0018] Optionally, the first support rod, the second support rod, and the positioning rod are arranged in multiple groups along the circumference of the storage table, and the two parallel side walls of the x-axis slide rail are provided with positioning grooves.

[0021] By adopting the above technical solution, the whole multi-axis engraving system can realize the rotation adjustment of the workpiece within the plane of the table, thereby expanding the angle range of laser engraving. Specifically, the matching design of the mounting frame and the rotating inner plate allows the workpiece placed on the table to rotate around the vertical axis, enhancing the flexibility and adaptability of the system, and is suitable for engraving workpieces with complex shapes or requiring multi-angle processing.

[0025] By adopting the above technical solution, the rotating inner plate can be accurately positioned and locked during the laser engraving process. Specifically, when the workpiece angle needs to be adjusted, the second cylinder can drive the second limit rod to withdraw from the fourth limit groove, thereby releasing the restriction on the rotating inner plate, so that the rotating inner plate can rotate freely under the drive of the third motor; when adjusted to the target angle, the second cylinder moves again, pushing the second limit rod through the third limit hole and inserting it into the corresponding fourth limit groove, so as to achieve reliable fixation of the rotating inner plate and ensure stability and accuracy during the engraving process. This design not only improves the flexibility of workpiece processing, but also effectively avoids processing errors caused by accidental movement of the rotating inner plate.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-10 This application is described in further detail.

[0029] Embodiment 1: The present application embodiment discloses a complete multi-axis engraving system. Figure 1 and Figure 2The engraving system includes an x-axis slide 1, a y-axis slide 2, a storage table 3, a mounting frame 4, a z-axis slide 5 and a laser head 6, wherein the x-axis slide 1 is provided with a first sliding seat 11 for sliding along its length direction, the y-axis slide 2 is detachably fixed to the first sliding seat 11 by means of bolts, etc., the y-axis slide 2 is provided with a second sliding seat 23 for sliding along its length direction, the storage table 3 is also detachably fixed to the second sliding seat 23 by means of bolts, etc., and a groove can be provided on the upper surface of the storage table 3 to match the clamping fixing structure to fix the workpiece to be processed, thereby improving the stability during processing. The z-axis slide 5 is suspended above the storage table 3 by the mounting frame 4, and at the same time, the height of the laser head 6 can be raised by the mounting frame 4 to accommodate the x-axis slide 1 and the y-axis slide 2 below; the laser head 6 is slidably provided on the z-axis slide 5, and an up-and-down control component 51 for controlling the up-and-down sliding of the laser head 6 is provided on the z-axis slide 5. The cross slide formed by the x-axis slide rail 1 and the y-axis slide rail 2 can control the placement table 3 to move on the plane, thereby increasing the format of the laser engraving; at the same time, the z-axis slide rail 5 is used to realize the up and down sliding setting of the laser head 6, so that the workpiece can be engraved in three dimensions.

[0030] Reference Figure 1 and Figure 2 The x-axis slide rail 1 is mainly composed of a metal shell 13 and a sliding control component 14 for controlling the sliding of the first sliding seat 11. The sliding control method between the x-axis slide rail 1 and the first sliding seat 11 can be implemented by a variety of structures, such as synchronous belt drive, gear rack drive or screw drive.

[0031] Exemplarily, when synchronous belt transmission is adopted, the sliding control assembly 14 mainly includes a motor, a synchronous wheel and a synchronous belt. The motor can control the rotation of the synchronous wheel, and the synchronous wheel drives the synchronous belt to rotate. The synchronous belt passes through the lower end of the first sliding seat 11 and is connected to the first sliding seat 11, so that the first sliding seat 11 can be driven to slide along the length direction of the x-axis slide rail 1; further, a guide rail can be set in the x-axis slide rail 1, and the lower end of the first sliding seat 11 is connected to a slider, and the slider slides on the guide rail, so as to improve the stability of the first sliding seat 11 when moving. The internal structure of the y-axis slide rail 2 is the same as that of the x-axis slide rail 1, and will not be repeated here. It should be noted that in order to seal and protect the interior of the x-axis slide rail 1, a thin metal baffle is provided on the surface of the x-axis slide rail 1 by bolts in the present application, and a corresponding give-way groove with a metal baffle is provided on the first sliding seat 11. When the first sliding seat 11 slides, the first sliding seat 11 will not interfere with the metal baffle.

[0032] Reference Figure 3 and Figure 4In the embodiment of the present application, further, the y-axis slide rail 2 can rotate relative to the x-axis slide rail 1, so that the y-axis slide rail 2 can rotate to be parallel to the x-axis slide rail 1, thereby reducing the packaging volume and facilitating the storage of the x-axis slide rail 1 and the y-axis slide rail 2. Specifically, a first connecting shaft 111 is fixed to the upper surface of the first sliding seat 11. The first connecting shaft 111 extends vertically upward and is rotatably connected to the y-axis slide rail 2, so that the y-axis slide rail 2 can rotate along the first connecting shaft 111. At the same time, a fixing member 21 is also provided on the y-axis slide rail 2. When the y-axis slide rail 2 rotates to be perpendicular to the x-axis slide rail 1 in the horizontal projection, the fixing member 21 can limit the rotation of the y-axis slide rail 2.

[0033] Specifically, the fixing member 21 includes a fixing rod 212 and a handle 211 connected to each other. The fixing rod 212 can slide through the metal shell 13 of the y-axis slide rail 2. The handle 211 is located outside the metal shell 13 to facilitate the control of the fixing rod 212. A seat is provided in the y-axis slide rail 2 to be rotatably connected to the first connecting shaft 111. A fixing hole is provided on the side wall of the first connecting shaft 111. An external thread is provided at one end of the fixing rod 212 away from the handle 211, and an internal thread is provided on the side wall of the fixing hole. When the y-axis slide rail 2 rotates to be perpendicular to the x-axis slide rail 1, the position of the fixing hole is in a straight line with the fixing rod 212. By connecting the fixing rod 212 with the thread of the fixing hole, the relative sliding between the first connecting shaft 111 and the y-axis slide rail 2 can be limited, that is, the sliding of the y-axis slide rail 2 can be limited.

[0034] Optionally, in order to achieve a detachable connection between the y-axis slide rail 2 and the first sliding seat 11, the first sliding seat 11 is divided into two upper and lower parts, and the two parts are detachably connected by bolts. The lower first sliding seat 11 slides on the x-axis slide rail 1, and the upper first sliding seat 11 is connected to the first connecting shaft 111.

[0035] In order to improve the stability of the y-axis slide rail 2 and ensure that the y-axis slide rail 2 can rotate smoothly, universal wheels 22 are connected to both ends of the y-axis slide rail 2, and the two universal wheels 22 and the first sliding seat 11 jointly support the y-axis. At the same time, in this embodiment, when the y-axis slide rail 2 slides to be parallel to the x-axis slide rail 1, the two universal wheels 22 slide to both ends of the x-axis slide rail 1 respectively.

[0036] Reference Figure 1 and Figure 5In the embodiment of the present application, the up-down control assembly 51 includes a first motor 511, a screw rod 512 and a guide rod 513, wherein the first motor 511 is fixed in the z-axis slide rail 5, and the output end of the first motor 511 is arranged vertically upward, the screw rod 512 is arranged in the z-axis slide rail 5 in a rotational direction, and the lower end of the screw rod 512 is connected to the output end of the first motor 511; the guide rod 513 is fixed in the z-axis slide rail 5 in a vertical direction. A third sliding seat 52 is arranged on the side wall of the z-axis slide rail 5 to slide up and down, and the laser head 6 is fixed on the side wall of the third sliding seat 52 by means of bolts or the like. The screw rod 512 is threadedly connected to pass through the third sliding seat 52, and the guide rod 513 slides through the third sliding seat 52. When the third motor is started, the third motor drives the screw rod 512 to rotate, which can drive the third sliding seat 52 to slide up and down, thereby driving the laser head 6 to slide up and down, and performing three-dimensional engraving on the objects placed on the storage table 3.

[0037] The implementation principle of the whole machine multi-axis engraving system of the embodiment of the present application is as follows: before engraving, the y-axis slide rail 2 is first rotated to a perpendicular state with the x-axis slide rail 1, and then the rotation of the y-axis slide rail 2 is limited by the fixing rod 212, and then the workpiece to be processed is fixed on the storage table 3, and the equipment can be started to engrave the workpiece. When engraving, the y-axis slide rail 2 and the storage table 3 are driven to move along the x-axis and y-axis directions by sliding the first sliding seat 11 and the second sliding seat 23, so that the workpiece can be engraved in two dimensions horizontally; by sliding the third sliding seat 52 up and down, the laser head 6 is driven to move up and down, and the workpiece can be engraved in three dimensions.

[0038] Embodiment 2: Reference Figure 6 and Figure 7 The difference between the embodiment of the present application and the embodiment 1 is that a flip adjustment component 7 is added. The flip adjustment component 7 is arranged between the y-axis slide rail 2 and the storage table 3, and is used to drive the storage table 3 to flip along a certain horizontal axis, so that the laser emitted by the laser head 6 can process the side wall of the workpiece, or, when the shape of the workpiece to be processed is larger at the top and smaller at the bottom, the lower end of the workpiece can be engraved, thereby adding more engraving scenes, such as three-dimensional engraving of a workpiece that is larger at the top and smaller at the bottom. In this embodiment, the rotation axis of the flip adjustment component 7 is parallel to the length direction of the y-axis slide rail 2, so the flip adjustment component 7 can drive the storage table 3 to flip along the length direction of the y-axis slide rail 2.

[0039] Reference Figure 6 and Figure 8Specifically, the flip adjustment component 7 includes a positioning seat 71, a rotating seat 72 and a second motor 73, wherein the positioning seat 71 is detachably fixed to the second sliding seat 23 by bolts, and the rotating seat 72 is rotatably set on the positioning seat 71, and the length directions of the positioning seat 71 and the rotating seat 72 are parallel to the length direction of the y-axis slide rail 2; the second motor 73 can also be fixed to the positioning seat 71 by bolts or the like, and the axial direction of the output end of the second motor 73 is parallel to the length direction of the positioning seat 71; the output end of the second motor 73 is fixedly connected to one end of the rotating seat 72, so that starting the second motor 73 can drive the rotating seat 72 to rotate along the axis of the output end of the second motor 73, that is, it can drive the storage table 3 to flip along the length direction of the y-axis slide rail 2.

[0040] Reference Figure 6 and Figure 8 The upper surface of the positioning seat 71 is provided with a rotation groove for the lower surface of the rotating seat 72 to abut and rotate. The lower surface of the rotating seat 72 is an arc-shaped surface, and the rotation groove corresponds to an arc-shaped groove. At the same time, in order to improve the stability of the rotating seat 72 during rotation, a guide strip can be arranged along the circumferential direction on the lower surface of the rotating seat 72, and a guide groove can be opened on the positioning seat 71. The cross-section of the guide strip is arranged to be T-shaped or dovetail-shaped, thereby ensuring the stability of the rotating seat 72 during rotation.

[0041] Reference Figure 6 and Figure 8 In the embodiment of the present application, a support assembly 8 may be further provided to support the storage table 3. Specifically, the support assembly 8 includes a first support rod 81, a second support rod 82, a positioning rod 83 and a first stopper 84. The first support rod 81 and the second support rod 82 are preferably configured as rectangular rods, and the upper end of the second support rod 82 is rotatably connected to the storage table 3. Specifically, the lower surface of the storage table 3 may be provided with a rotating shaft in the form of a support, and the rotating shaft passes through the second support rod 82 and is rotatably connected to the second support rod 82; the lower end of the second support rod 82 is slidably inserted into the first support rod 81, and the positioning rod 83 is fixedly provided on the side wall of the lower end of the first support rod 81. A positioning groove 12 is provided on the side wall of the x-axis slide rail 1 facing the first support rod 81, and the positioning groove 12 extends along the length direction of the x-axis slide rail 1, and the end of the positioning rod 83 away from the first support rod 81 is inserted and slides into the positioning groove 12.

[0042] Reference Figure 6 and Figure 8, the first limiting member 84 is used to limit the second support rod 82 from sliding up and down in the first support rod 81. Specifically, the first limiting member 84 includes a first cylinder 841, a connecting rod 842 and a first limiting rod 843. The first cylinder 841 is fixed on the positioning seat 71. The first limiting rod 843 is connected to the telescopic axis of the first cylinder 841 through the connecting rod 842. The length direction of the telescopic axis of the first cylinder 841 is parallel to the length direction of the y-axis slide rail 2. The length direction of the first limiting rod 843 is also parallel to the length direction of the y-axis slide rail 2. A first limiting hole 811 is provided on the side wall of the first support rod 81 facing the first limiting rod 843. A second limiting hole 821 is provided on the side of the second support rod 82 facing the first limiting rod 843 along the vertical direction. Both the first limiting hole 811 and the second limiting hole 821 are set as waist-shaped holes, and the extension direction of both is parallel to the length direction of the x-axis slide rail 1. When the first cylinder 841 is started, the first limiting rod 843 can be driven through the connecting rod 842 to pass through the first limiting hole 811 and the second limiting hole 821 in sequence, thereby limiting the second support rod 82 from sliding up and down relative to the first support rod 81, that is, supporting the storage table 3 above.

[0043] It should be noted that since the second limiting holes 821 are arranged at intervals, in order to ensure that the first limiting rod 843 can always pass through the second limiting hole 821, the second motor 73 preferably uses a stepper motor and can rotate a fixed angle each time so that the first limiting hole 811 can always be aligned with a second limiting hole 821.

[0044] Optionally, in order to further improve the supporting effect on the storage table 3, multiple groups of the first support rods 81 and the second support rods 82 can be arranged along the circumference of the storage table 3. In this embodiment, four groups of the first support rods 81 and the second support rods 82 are arranged, and four first limiting rods 843 are also arranged. Through the connection of the connecting rod 842, the four first limiting rods 843 are arranged one by one with the first limiting holes 811 of the first support rod 81, so that the first cylinder 841 can simultaneously control the four first limiting rods 843 to be inserted into the first limiting holes 811 on the four first support rods 81 respectively.

[0045] In other embodiments, an abutment method can be used instead of the cooperation between the first limit rod 843 and the second limit hole 821, that is, a side wall of the second support rod 82 facing the first limit rod 843 is set to a non-slip frosted surface, and the corresponding end face of the first limit rod 843 is also set to an anti-slip surface. The second support rod 82 is limited by controlling the first limit rod 843 to pass through the first limit hole 811 and making the end face of the first limit rod 843 press against the side wall of the second support rod 82. At this time, the upper storage platform 3 is supported by the friction force between the first limit rod 843 and the second support rod 82; in this way, the control accuracy of the rotation angle of the storage platform 3 can be further increased.

[0046] The implementation principle of a whole-machine multi-axis engraving system in an embodiment of the present application is as follows: before use, the flip adjustment component 7 is first installed on the multi-axis engraving system, and then when it is necessary to engrave the side wall of the workpiece, the second motor 73 is first started to drive the placement table 3 to flip a certain angle, and the placement table 3 drives the second support rod 82 to move up and down when flipping. At the same time, the placement table 3 will also drive the first support rod 81 and the second support rod 82 to move a certain distance along the length direction of the x-axis slide rail 1. After the placement table 3 is flipped, the first cylinder 841 is started, and the first cylinder 841 drives the first limit rod 843 to pass through the first limit hole 811 and the second limit hole 821 in sequence, that is, it can limit the second support rod 82 from moving up and down, that is, it can achieve locking of the position of the second support rod 82, thereby ensuring the stability of the placement table 3 during the processing.

[0047] Embodiment 3: Reference Fig. 9 and Fig.10 The difference between the embodiment of the present application and embodiment 2 is that a rotation adjustment component is added, and the storage table 3 is set as a rotatable structure. The rotation adjustment component is used to drive the workpiece on the storage table 3 to continue to rotate on the basis of flipping and tilting, so as to facilitate circumferential engraving of the workpiece.

[0048] Reference Fig. 9 and Fig.10 In the embodiment of the present application, the storage table 3 includes an installation outer frame 31 and a rotating inner plate 32, wherein the installation outer frame 31 is fixed to the rotating seat 72 by means of bolts or the like, and the rotating inner plate 32 is rotatably arranged in the installation outer frame 31; correspondingly, a groove can be provided on the upper surface of the rotating inner plate 32 to cooperate with the clamping fixing structure to fix the workpiece to be processed; at the same time, in order to reduce the volume, the rotating inner plate 32 and the installation outer frame 31 can be set to a circular structure.

[0049] The rotation adjustment assembly includes a power member 91 and a second stop member 92. The power member 91 can be a third motor, which can be fixed on the mounting frame 31 or the rotating seat 72. In this embodiment, in order to improve the compactness of the device, the third motor is embedded in the rotating seat 72, and the output shaft of the third motor rotates through the rotating seat 72 and the mounting frame 31, and is fixedly connected to the rotating inner plate 32. Therefore, when the second motor 73 is used to rotate the storage table 3 to engrave the side wall of the workpiece, the third motor can be turned on synchronously to drive the rotating inner plate 32 and the workpiece arranged on the rotating inner plate 32 to rotate, and the side wall of the workpiece is engraved circumferentially.

[0050] Reference Fig. 9 and Fig.10In an optional embodiment, the second limiting member 92 includes a second cylinder and a second limiting rod. The second cylinder is preferably fixed on the rotating seat. In order to facilitate the installation of the second cylinder, a rectangular plate can be fixed on the side wall of the rotating seat, and the second cylinder is installed by the rectangular plate. The telescopic axis of the second cylinder extends toward the storage table 3, and the second limiting rod is connected to the telescopic axis of the second cylinder. The length direction of the second limiting rod is parallel to the axial direction of the output shaft of the third motor. A third limiting hole 311 for the second limiting rod to pass through is provided on the side wall of the mounting outer frame 31, and a fourth limiting groove 321 for the second limiting rod to be inserted is provided on the side wall of the rotating inner plate 32 facing the rotating seat 72; the second cylinder can drive the second limiting rod to pass through the third limiting hole 311 and be inserted into the fourth limiting groove 321, thereby fixing the rotating inner plate 32.

[0051] When the workpiece angle needs to be adjusted, the second cylinder can drive the second limiting rod to withdraw from the fourth limiting groove 321, thereby releasing the restriction on the rotating inner plate 32, so that the rotating inner plate 32 can rotate freely under the drive of the third motor; when the target angle is adjusted, the second cylinder acts again, pushing the second limiting rod through the third limiting hole 311 and inserting it into the corresponding fourth limiting groove 321, so as to achieve reliable fixation of the rotating inner plate 32 and ensure stability and precision during the engraving process. This design not only improves the flexibility of workpiece processing, but also effectively avoids processing errors caused by accidental movement of the rotating inner plate 32.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
