DETAILED DESCRIPTION

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides a laser marking multi-axis positioning device, such as Figure 1-4 As shown, it includes a support platform 1; a marking body 2 arranged above the support platform 1; and an adjustment mechanism arranged beside the marking body 2; wherein the adjustment mechanism includes: a screw slide 301 sliding above the support platform 1; a first connecting plate 302 arranged at the moving end of the screw slide 301; a second connecting plate 306 rotating on the outside of the first connecting plate 302; a first motor 303 arranged on the outer wall of the other side of the first connecting plate 302, the output end of the first motor 303 is fixedly connected with the end key of the second connecting plate 306; an operating table 304 rotating above the second connecting plate 306; a second motor 305 arranged on the outside of the second connecting plate 306, the output end of the second motor 305 is fixedly connected with the end key of the operating table 304; and a clamping member arranged above the operating table 304.

[0023] It should be noted that, since the existing laser marking device faces the frequent need to adjust the contact surface between the workpiece and the marking head when processing the workpiece, this adjustment is not only time-consuming and labor-intensive, but may also lead to inaccurate marking position, thereby affecting the marking quality and consistency. The present solution has multi-dimensional positioning and adjustment functions, including high-precision adjustment of longitudinal, lateral, vertical and horizontal planes. At the same time, its clamping parts are flexibly designed to adapt to workpieces of various shapes and sizes, expanding the scope of application. The addition of rubber pad 6 enhances the uniformity and stability of clamping, prevents the workpiece from sliding, further improves the adaptability and stability of the device, expands the scope of application and adaptability of the device, and realizes more flexible and diversified marking needs.

[0024] Specifically, in this embodiment, the scheme mainly includes a support platform 1, a marking body 2 and an adjustment mechanism; the adjustment mechanism is the core part of the device, which includes a screw slide 301, a first connecting plate 302, a second connecting plate 306, a first motor 303 and a second motor 305; before the work starts, the workpiece to be marked is placed on the operating table 304, and the clamping member firmly clamps the workpiece to ensure that the workpiece does not move during the marking process; next, the screw slide 301 starts its longitudinal horizontal sliding on the support platform 1, and the screw slide 301 is driven by a motor, and its moving end drives the operating table 304 to move horizontally, and this double sliding mechanism allows the operating table 304 to move freely in the longitudinal and horizontal directions, so that the distance between the workpiece and the marking body 2 can be accurately adjusted; this distance adjustment is crucial to ensure the accuracy and clarity of the marking position;

[0025] The first motor 303 drives the second connecting plate 306 to rotate. This rotation changes the vertical angle between the operating table 304 and the workpiece. By adjusting this angle, marking of different parts of the workpiece can be achieved, or workpieces of different shapes and curved surfaces can be adapted. This vertical angle adjustment increases the flexibility and adaptability of the device.

[0026] At the same time, the second motor 305 is started, which drives the operating table 304 to rotate relative to the second connecting plate 306. This rotation allows the direction or angle of the workpiece to be adjusted in the horizontal plane. This adjustment is very useful for ensuring the consistency of the marking direction with the workpiece surface or adapting to workpieces with complex shapes. By adjusting the angle in the horizontal direction, the uniformity and consistency of the marking effect can be ensured.

[0027] In summary, through the precise control and flexible operation of the adjustment mechanism, multi-dimensional positioning and marking of the workpiece are achieved. This multi-dimensional positioning not only improves the accuracy and consistency of marking, but also expands the application range and adaptability of the device, achieving high-quality laser marking effects.

[0028] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the clamping member includes: a group of vertical plates 401 symmetrically arranged on the upper surface of the operating table 304; first hydraulic rods 402 are arranged on opposite sides of the two vertical plates 401; and fastening plates 403 are arranged at the output ends of the two first hydraulic rods 402.

[0029] In this embodiment, when the first hydraulic rod 402 is started, its output end will extend forward, thereby pushing the fastening plate 403 connected thereto to move, firmly clamping the workpiece on the operating table 304, so that the device can better adapt to workpieces of different sizes and shapes, thereby improving production efficiency and product quality.

[0030] In a further preferred embodiment of the present invention, Figure 4 As shown, a plurality of return springs 5 ​​are disposed on the outer side of the fastening plate 403 , a damper is disposed inside each of the return springs 5 ​​, and a rubber pad 6 is disposed on the side of the return springs 5 ​​away from the fastening plate 403 .

[0031] In this embodiment, when the workpiece is placed on the operating table 304 and fixed by the clamping member, the reset spring 5 will be squeezed by the workpiece and deformed, generating a certain reaction force. This reaction force can help the fastening plate 403 to fit the surface of the workpiece more closely and prevent the workpiece from moving during the marking process. The rubber pad 6 is a soft material with good elasticity. It can increase the contact area between the reset spring 5 and the workpiece and improve the uniformity and stability of the clamping. At the same time, the rubber pad 6 also has a certain anti-slip effect, which can prevent the workpiece from sliding or displacing during the clamping process.

[0032] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a group of second hydraulic rods 7 are arranged on one side of the upper surface of the support platform 1 , and the output ends of two second hydraulic rods 7 are connected to the outer side wall of the screw slide 301 .

[0033] In this embodiment, by controlling the extension and retraction of the second hydraulic rod 7 , the position of the screw slide 301 can be accurately adjusted, thereby adjusting the distance between the workpiece and the marking body 2 .

[0034] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a limiting slide groove 8 for sliding of the screw slide 301 is provided on the upper surface of the support platform 1 , and the limiting slide groove 8 is consistent with the width direction of the support platform 1 .

[0035] In this embodiment, by providing a limiting slide groove 8 on the upper surface of the support platform 1, effective guidance and restriction of the screw slide 301 can be achieved, thereby ensuring its stability and accuracy during the marking process.

[0036] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the outer surface of the rubber pad 6 is provided with anti-slip textures.

[0037] In this embodiment, the anti-slip texture is a design that increases friction by changing the surface morphology of the rubber pad 6. These textures can be regular patterns, such as grids, stripes or dots, or random unevenness. Their main function is to increase the contact area between the rubber pad 6 and the workpiece, while increasing the friction coefficient, thereby preventing the workpiece from sliding during the clamping process.

[0038] Working principle: When the device is used, the workpiece to be marked is placed on the operating table 304, the first hydraulic rod 402 is started, and its output end extends forward, thereby pushing the fastening plate 403 connected thereto to move, and the workpiece is firmly clamped on the operating table 304, so that the device can better adapt to workpieces of different sizes and shapes, and improve production efficiency and product quality;

[0039] When clamping the workpiece, the reset spring 5 will be squeezed by the workpiece and deformed, generating a certain reaction force. This reaction force can help the fastening plate 403 to fit the workpiece surface more closely, preventing the workpiece from moving during the marking process. The rubber pad 6 is a soft material with good elasticity, which can increase the contact area between the reset spring 5 and the workpiece, improve the uniformity and stability of the clamping, and at the same time, the rubber pad 6 also has a certain anti-slip effect, which can prevent the workpiece from sliding or moving during the clamping process.

[0040] Next, by controlling the extension and retraction of the second hydraulic rod 7, the position of the screw slide 301 can be accurately adjusted to achieve longitudinal horizontal sliding. The screw slide 301 is driven by a motor, and its moving end drives the operating table 304 to move horizontally. This dual sliding mechanism allows the operating table 304 to move freely in the longitudinal and horizontal directions, so that the distance between the workpiece and the marking body 2 can be accurately adjusted; this distance adjustment is crucial to ensure the accuracy and clarity of the marking position;

[0041] The first motor 303 drives the second connecting plate 306 to rotate. This rotation changes the vertical angle between the operating table 304 and the workpiece. By adjusting this angle, marking of different parts of the workpiece can be achieved, or workpieces of different shapes and curved surfaces can be adapted. This vertical angle adjustment increases the flexibility and adaptability of the device.

[0042] The second motor 305 is started, which drives the operating table 304 to rotate relative to the second connecting plate 306. This rotation allows the direction or angle of the workpiece to be adjusted in the horizontal plane. This adjustment is very useful for ensuring the consistency of the marking direction and the workpiece surface or adapting to workpieces with complex shapes. By adjusting the angle in the horizontal direction, the uniformity and consistency of the marking effect can be ensured;

[0043] In summary, through the precise control and flexible operation of the adjustment mechanism, multi-dimensional positioning and marking of the workpiece are achieved. This multi-dimensional positioning not only improves the accuracy and consistency of marking, but also expands the application range and adaptability of the device, achieving high-quality laser marking effects.
