[0042] Please see Figures 1 to 3 This embodiment proposes a multi-axis laser engraving device for laser engraving products. During the laser engraving process, the product can be adjusted in multiple degrees of freedom to adapt to different laser engraving requirements. The following product is a watch case as an example. During the production process of the watch case, laser engraving is required on different inner sidewalls and several outer sidewalls of the watch case.

[0043] The multi-axis laser engraving equipment includes a planar moving part 1, an angle adjusting part 2, a clamping part 3, and a laser engraving part 4. The planar moving part 1 has a moving end 121 that can move along any planar direction. The angle adjusting part 2 is disposed on the moving end 121 and has at least two rotating shafts that rotate around different axes, so that the rotating end 211 of the angle adjusting part 2 can rotate around different directions. The clamping part 3 is disposed on the rotating end 211 and is used to clamp the product. The laser engraving part 4 is directly opposite the part of the product to be laser engraved and is used to laser engrave the product.

[0044] Understandably, when the product is held by the clamping part 3, the planar moving part 1 can provide the product with planar degrees of freedom, and the angle adjustment part 2 can provide the product with rotational degrees of freedom in at least two directions. This setting can ensure that the posture of the product can be adjusted with multiple degrees of freedom during the laser engraving process to adapt to the laser engraving requirements at different angles, and can avoid clamping the product multiple times during the laser engraving process, thereby improving the laser engraving efficiency of the product.

[0045] Specifically, in this embodiment, the aforementioned planar directions include the X-axis and Y-axis directions, which are perpendicular to each other. The planar moving part 1 includes a first adjusting member 11 and a second adjusting member 12. The first adjusting member 11 is arranged along the X-axis direction; the second adjusting member 12 is arranged along the Y-axis direction. The first adjusting member 11 is used to drive the second adjusting member 12 to move along the X-axis direction. The second adjusting member 12 has a moving end 121 connected to the angle adjusting part 2, and the second adjusting member 12 is used to drive the angle adjusting part 2 to move along the Y-axis direction. It can be understood that the first adjusting member 11 has a driving end that moves along the X-axis direction, and the second adjusting member 12 is disposed at the driving end. Under the action of the first adjusting member 11 and the second adjusting member 12, the moving end 121 can move along the X-axis direction and the Y-axis direction respectively to reach any position on the plane to meet different laser engraving requirements.

[0046] The first adjusting member 11 and the second adjusting member 12 are preferably linear modules in the prior art. The structure of the linear module is in the prior art and will not be described in detail here.

[0047] In this embodiment, the angle adjustment part 2 includes at least two rotating parts 21 and several first connecting brackets 22. The first connecting brackets 22 are fixedly mounted on the rotating shaft of one of the rotating parts 21 and are used to fix the other rotating part 21. The first rotating part 21 is fixed to the moving end 121, and the last rotating part 21 is used to connect to the clamping part 3. It can be understood that the rotating parts 21 and the first connecting brackets 22 are arranged sequentially at intervals. The outer shell of the first rotating part 21 is disposed on the moving end 121. Under the action of the moving end 121, the first rotating part 21 (hereinafter referred to as the first rotating part 21) can move along the plane, so that the product has the freedom to move along the plane. The first connecting brackets 22 are disposed on the rotating shaft of the first rotating part 21. Under the action of the first rotating part 21, it can rotate around the axis of its rotating shaft, so that the product has the freedom to rotate in one direction. The first rotating part 21 can also be connected to the moving end 121 through the first connecting brackets 22. The rotating component 21 at the end (hereinafter referred to as the end rotating component 21) can be connected to the clamping part 3 as a connecting structure. That is, the rotating shaft of the end rotating component 21 is the rotating end 211 of the angle adjustment part 2. With this setting, the product can have the freedom to rotate around different directions to adapt to different laser engraving requirements of the product, thereby avoiding the need to clamp the product multiple times during the laser engraving process and thus improving the laser engraving efficiency of the product.

[0048] The number of rotating parts 21 can be two, three or four, depending on actual production needs, and no specific restrictions are imposed here. The rotating parts 21 are preferably rotating structures such as hollow rotary motors in the prior art. Their specific structures and installation methods are all prior art and will not be described in detail here.

[0049] Furthermore, the first connecting bracket 22 includes a first connecting plate 221 and a second connecting plate 222. The first connecting plate 221 is disposed on the shaft of one of the rotating parts 21. The second connecting plate 222 is connected to the first connecting plate 221, and there is an angle between the first connecting plate 221 and the second connecting plate 222. The second connecting plate 222 is used to fix another rotating part 21. It can be understood that any two adjacent rotating parts 21 are connected by the first connecting bracket 22. When installing the rotating parts 21, the outer shell of one mounting part can be fixed to the second connecting plate 222 by bolts or other mounting structures, and the shaft of the other mounting part can be fixed to the first connecting plate 221 by bolts or other mounting structures. The angle between the first connecting plate 221 and the second connecting plate 222 allows the shafts of multiple rotating parts 21 to extend in different directions, so that the product has the freedom to rotate in different directions.

[0050] Specifically, in this embodiment, there are two rotating members 21, and the axes corresponding to the two rotating members 21 are arranged perpendicularly. It can be understood that the two rotating members 21 are respectively referred to as the first rotation and the second rotation. The first rotation is located at the moving end 121, and its axis is connected to the first connecting plate 221. The outer shell of the second rotation is located on the second connecting plate 222, and its axis is connected to the clamping part 3. The axis of the first rotation is oriented along the Y-axis to give the product a degree of freedom in the RY direction. The axis of the second rotation can be adjusted with the rotation of the first connecting bracket 22 to give the product a degree of freedom in the corresponding rotation direction.

[0051] In this embodiment, the clamping part 3 includes a carrier plate 31 and a gripper 32. The carrier plate 31 is connected to the rotating end 211 and is used to support the product. The gripper 32 is disposed on the carrier plate 31 and is used to clamp the product. It is understood that before laser engraving the product, the product needs to be placed on the carrier plate 31, and then the gripper 32 is used to clamp the outer wall of the product to ensure the stability of the product during the laser engraving process. The gripper 32 is preferably a pneumatic gripper finger or some other clamping structure in the prior art. The structure of the pneumatic gripper finger is prior art and will not be described in detail here.

[0052] In addition, to ensure the stability of the product when it is clamped, the clamping part 321 of the gripper 32 is adapted to conform to the outer wall of the product to ensure that the clamping part 321 fits the outer wall of the product.

[0053] Furthermore, the clamping part 3 also includes a positioning element 33 disposed on the carrier plate 31, which is used to position the product. It can be understood that the positioning element 33 can ensure the positioning accuracy when the product is placed on the carrier plate 31, thereby ensuring the laser engraving accuracy of the product and improving the product processing yield.

[0054] In this specific embodiment, the bottom of the watch case is provided with a positioning hole for assembly. Therefore, the positioning component 33 is preferably a positioning pin that matches the positioning hole. With this configuration, no additional positioning structure needs to be set on the watch case during the positioning process, which further improves the laser engraving efficiency of the product.

[0055] During the laser engraving process on a product, certain areas on one or more outer walls of the product need to be laser-engraved. To facilitate laser engraving, the thickness of the gripper 32 is less than the thickness of the product. This design exposes the gripper 32 to the areas on the outer walls of the product that require laser engraving, making laser engraving easier.

[0056] Furthermore, a portion of the bottom of the product requires laser engraving. To facilitate this process, the carrier plate 31 has through holes 311, which allow space for the laser engraving path of the laser engraving unit 4. This design adapts to different laser engraving requirements, ensuring comprehensive laser engraving and avoiding the need for secondary clamping of the product, thereby improving laser engraving efficiency.

[0057] Furthermore, the clamping part 3 is detachably mounted on the rotating end 211. Understandably, when laser engraving different product models, the model of the clamp 32 needs to be adjusted. By replacing the corresponding clamping part 3, the model of the clamp 32 and the position of the positioning pin can be adjusted to ensure the stability of different products during laser engraving.

[0058] In this embodiment, the laser engraving unit 4 includes a laser emitter 41 and a visual positioning component 42. The laser emitter 41 emits laser light for laser engraving onto the product; the visual positioning component 42 is electrically connected to the laser emitter 41 and is used to position the product. It can be understood that before laser engraving the product, the visual positioning component 42 positions the laser engraving starting point and feeds back the position information to the laser emitter 41. After determining the position information, the laser emitter 41 can begin laser engraving. The visual positioning component 42 further ensures the accuracy of the laser engraving.

[0059] The visual positioning component 42 includes a CCD camera, which is a prior art technology. The specific structure and use of the CCD camera are prior art technologies and will not be described in detail here.

[0060] Furthermore, the multi-axis laser engraving equipment also includes a spacing adjustment unit 5, which is disposed between the planar moving unit 1 and the laser engraving unit 4. The visual positioning component 42 is electrically connected to the spacing adjustment unit 5, enabling the spacing adjustment unit 5 to adjust the spacing between the laser engraving unit 4 and the product in real time. It is understood that during the adjustment process, the distance between the product and the laser emitter 41 will change. Under the action of the spacing adjustment unit 5, the spacing between the laser engraving unit 4 and the product can be adjusted in real time to ensure that the focus of the laser engraving always falls on the surface of the product, thereby guaranteeing laser engraving accuracy and quality.

[0061] Specifically, in this embodiment, the laser emitter 41 and the product are spaced apart along the Z-axis, and are perpendicular to each other along the X-axis, Y-axis, and Z-axis. The spacing adjustment part 5 includes an adjustment mechanism 51 arranged along the Z-axis and a second connecting bracket 52 disposed at the adjustment end of the adjustment mechanism 51. Under the action of the adjustment mechanism 51, the second connecting bracket 52 can move along the Z-axis. The laser emitter 41 and the visual positioning component 42 are both disposed on the second connecting bracket 52, and the visual positioning component 42 can provide feedback on the real-time position of the product to the adjustment mechanism 51, so as to adjust the position of the second connecting bracket 52. The adjustment mechanism 51 is preferably a linear module in the prior art. The structure of the linear module is prior art and will not be described in detail here.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
