Technical Field

[0001] This utility model belongs to the field of laser marking technology, specifically relating to a tilting dual-head laser marking machine. Background Technology

[0002] The tilting dual-head laser marking machine is an innovative type of laser marking equipment. It combines the high efficiency of a dual-head laser marking machine with the flexibility of a tilting design, making it suitable for production scenarios requiring high precision and multi-angle marking. Compared to ordinary horizontal dual-head laser marking machines, the tilting dual-head laser marking machine's structure allows the marking head to operate at a certain angle, thus enabling more flexible handling of workpieces with different shapes and surface requirements.

[0003] Problems with existing technology:

[0004] While existing tilting dual-head laser marking machines can mark the same workpiece from two sides simultaneously, some workpieces require marking from multiple sides. This necessitates adjustments by the operator, resulting in low work efficiency. Furthermore, they lack adaptive devices to accommodate workpieces of different shapes and sizes when clamping them for marking. Utility Model Content

[0005] The purpose of this invention is to provide a tilting dual-head laser marking machine, which can simultaneously mark two workpieces to be marked by means of a lifting frame, laser, and angle motor. Moreover, it can mark the same workpiece by two lasers. With the help of a clamping seat, all surfaces of the workpiece except the bottom can be marked in one go. During the marking process, the machine can clamp the workpiece and automatically adapt to workpieces of different sizes and shapes.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figure 1 - Figure 4 As shown, a tilting dual-head laser marking machine includes: a worktable 7, a lifting frame 1 is provided on one side of the top of the worktable 7, an angle motor 4 is vertically slidably installed on one side of the lifting frame 1, the output end of the angle motor 4 is rotatably connected to a laser 2, a placement plate 6 is also provided on the top of the worktable 7, two clamping seats 3 are provided on the top of the placement plate 6, and the workpiece 5 to be marked is placed in the middle position of the clamping seats 3.

[0028] When laser marking is required, the workpiece 5 to be marked is first placed in the middle position of the clamping seat 3. Then, by controlling the lateral movement of the lifting frame 1, the driving device inside the lifting frame 1 drives the angle motor 4 to move up and down. Then, by controlling the angle motor 4 to rotate the orientation of the laser 2, the workpiece 5 to be marked is marked.

[0029] See attached document Figure 5 - Figure 7The clamping base 3 includes a rotating disk 302. A storage groove is provided on the placement plate 6 corresponding to the position of the rotating disk 302. A rotating motor 306 is provided at the bottom of the rotating disk 302. The rotating motor 306 is fixedly installed on the top of the worktable 7. The output end of the rotating motor 306 is fixedly connected to the rotating disk 302. Clamping sliding blocks 301 are provided around the rotating disk 302. A sliding groove is provided on the rotating disk 302 corresponding to the position of the clamping sliding block 301. A sliding clamping motor 305 is fixedly installed on the outside of the rotating disk 302 corresponding to the clamping sliding block 301. A bolt rod 304 is fixedly connected to the output end of the sliding clamping motor 305. A central frustum 303 is fixedly connected to the middle position of the rotating disk 302. The end of the bolt rod 304 is rotatably connected to the central frustum 303. A sliding threaded block 307 is fixedly connected to the bottom of the clamping sliding block 301. The sliding threaded block 307 is sleeved on the outside of the bolt rod 304 and threadedly connected to it.

[0030] According to the above structure, before marking the workpiece 5, it needs to be limited to facilitate rotation so that multiple sides can be marked, reducing the need for manual intervention. First, the workpiece 5 to be marked is placed in the middle of the clamping seat 3. Then, the sliding clamping motor 305 is started to drive the bolt rod 304 to rotate. At this time, the sliding threaded block 307, which is threadedly connected to the bolt rod 304, drives the clamping sliding block 301 to move. When multiple clamping sliding blocks 301 approach the workpiece 5 to be marked, they are limited. After one side of the workpiece 5 is marked, the rotating motor 306 is started to rotate the rotating disk 302, which in turn rotates the clamping sliding block 301 and the workpiece 5 to be marked, so that multiple sides of the workpiece 5 can be marked.

[0031] See attached document Figure 7 - Figure 8 Multiple clamping sliding blocks 301 are provided with a force-measuring sliding plate 308 on one side near the central truncated cone 303. The clamping sliding block 301 has a clamping groove corresponding to the position of the force-measuring sliding plate 308. The force-measuring sliding plate 308 is slidably installed with the clamping groove. A clamping spring 311 is fixedly connected between the force-measuring sliding plate 308 and the clamping groove. An electrical connecting post 309 is fixedly installed inside the clamping groove corresponding to the clamping sliding block 301. An electrical connecting post 310 is fixedly installed on the force-measuring sliding plate 308 corresponding to the position of the electrical connecting post 309. A friction strip is provided on the side of the force-measuring sliding plate 308 near the central truncated cone 303.

[0032] According to the above structure, when the clamping sliding block 301 approaches the workpiece 5 to be marked, since the shapes and sizes of the workpieces to be marked are different, multiple clamping sliding blocks 301 need to move different distances to clamp the workpieces to be marked, and the clamping force must be the same. Through the reaction force of the clamping sliding block 301 clamping the object, and the object pushing the rotating disk 302 to move into the clamping groove inside the clamping sliding block 301, the clamping spring 311 is compressed until the electrical connection post 1 309 contacts the electrical connection post 2 310. Both the electrical connection post 1 309 and the electrical connection post 2 310 are connected to weak current. When the two contact, a path is formed to transmit a signal to the sliding clamping motor 305 to stop it. At this time, the clamping sliding block 301 moves coaxially. At the same time, the clamping force of multiple clamping sliding blocks 301 on the workpiece 5 to be marked is equal to the force of the elastic deformation of the clamping spring 311 and the clamping force. The friction strip is used to increase the friction with the workpiece 5 to be marked.

[0033] The working principle of this utility model is as follows: When laser marking is required, the workpiece 5 to be marked is first placed in the middle position of the clamping seat 3. Then, by controlling the lateral movement of the lifting frame 1, the driving device inside the lifting frame 1 drives the angle motor 4 to move up and down. Then, by controlling the angle motor 4 to rotate the orientation of the laser 2, the sliding clamping motor 305 is started to drive the bolt rod 304 to rotate. At this time, the sliding threaded block 307, which is threadedly connected to the bolt rod 304, drives the clamping sliding block 301 to move. When multiple clamping sliding blocks 301 approach the workpiece 5 to be marked, they are limited. After one side of the workpiece 5 to be marked is finished, the rotating motor 306 is started to rotate the rotating disk 302, which rotates the clamping sliding block 301 and the workpiece 5 to be marked, for marking multiple sides of the workpiece 5 to be marked.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
