[0055] As Figures 1 to 9 The utility model discloses a lens embedded type integrated laser marking machine, including: host computer 1 and swing seat 2. The host computer 1 has the accommodation groove 111, and the laser generator (not shown) is arranged in the host computer 1. Swing seat 2 is at least partially located in the accommodation groove 111, and swing seat 2 is rotatably connected to the host computer 1, and swing seat 2 has a cavity, a light inlet 21 and a galvanometer assembly 22 arranged in the cavity, the light inlet 21 is communicated with the cavity, and the light inlet 21 is located on the rotation axis of swing seat 2. The light wave emitted by the laser generator can pass through the light inlet 21 and be incident on the galvanometer assembly 22. The lens embedded type integrated laser marking machine of the application can stably adjust the direction of laser light path by the rotatable swing seat 2, and the light inlet 21 is located on the rotation axis, which meets the marking requirements of different positions and angles, and can realize flexible adjustment of the laser marking direction. At the same time, the swing seat 2 is partially located in the accommodation groove 111, which not only reduces the overall volume of the marking machine and saves production space, but also makes the swing seat 2 not exposed to the host computer 1, so that it is not interfered by external structures and is not easy to be damaged by knocking, and the use safety is good.
[0056] As Figure 1 , Figure 2 And Figure 5 The inner wall of the accommodation groove 111 is provided with a rotating cooperation groove 1111 on the opposite side, and the opposite sides of the swing seat 2 are provided with a convex shaft 23, and the two convex shafts 23 are rotatably inserted into the corresponding rotating cooperation grooves 1111.

And the light inlet 21 is arranged on the convex shaft 23, which can accurately guide the laser into the swing seat 2, avoid the light path deviation caused by the structure rotation, and ensure the marking precision.
[0057] In one possible implementation, as Figure 4 , Figure 5 And Figure 6As shown, the host 1 comprises a main shell 11, a first block 12 and a second block 13, the main shell 11 has the accommodating groove 111. A rotating fitting groove 1111 is arranged on a side wall of the accommodating groove 111, the first block 12 is arranged in the accommodating groove 111, and the first block 12 has a first notch 121. The second block 13 is detachably connected to the main shell 11 and / or the first block 12, and the second block 13 has a second notch 131, the second notch 131 and the first notch 121 form another rotating fitting groove 1111. By splitting the rotating fitting groove 1111 into the first notch 121 of the first block 12 and the second notch 131 of the second block 13, and the second block 13 is detachably connected to the main shell 11 and / or the first block 12, so that the complete rotating fitting groove 1111 can be flexibly assembled to meet the rotating requirement of the convex shaft 23, and when the convex shaft 23 and the swing seat 2 are installed or maintained, the second block 13 can be quickly operated by being detached, without the need to disassemble the main shell 11 as a whole, greatly improving the convenience of assembly and maintenance.
[0058] As shown in Figure 1 , Figure 4 and Figure 6 , the second block 13 can be inserted or extracted from the accommodating groove 111, and a through groove 132 is arranged on the second block 13. A fastener can be connected to the first block 12 through the through groove 132, and the fastener can be tightened or released by rotating the fastener. The first block 12 is provided with a threaded groove 122, and the fastener can be a screw. The shank of the screw penetrates the through groove 132 and is threadedly connected to the screw groove, and the cap of the screw is limited on the side of the second block 13 away from the first block 12. Such a structure not only enables the convex shaft 23 to be quickly assembled and disassembled by pulling out the second block 13, but also enables the convex shaft 23 to be directly clamped or released by rotating the fastener, so as to realize quick positioning of the convex shaft 23 during installation and flexible adjustment of the rotating tightness to adapt to different marking scenes, thereby improving the efficiency of assembly, debugging and later maintenance of the lens embedded type integrated laser marking machine of the present application.
[0059] As shown in Figure 1As shown in the drawings, the accommodating groove 111 has a first opening and a second opening, which are arranged on two adjacent outer wall surfaces of the main shell 11 and are connected to each other. This can greatly expand the activity space of the swing seat 2, so that it can realize a rotation swing of about ninety degrees, significantly increase the swing angle of the swing seat 2, and adapt to more different positions and angles of workpiece marking requirements, such as processing different areas of the workpiece side surface, end surface and the like, and further improve the application scene range of the lens embedded type integrated laser marking machine.
[0060] In a possible implementation, as shown in the drawings, Figure 1 and Figure 4 As shown in the drawings, the lens embedded type integrated laser marking machine comprises an isolation cover 3, which is arranged on the inner wall of the accommodating groove 111, and the swing seat 2 is located inside the isolation cover 3. The isolation cover 3 can completely separate the internal circuit of the main machine 1 from the galvanometer assembly 22 inside the swing seat 2, and at the same time, it can close the circuit of the galvanometer assembly 22 itself, which can avoid the mutual interference of the two types of circuits from the root, and also prevent the invasion of dust and impurities from the outside to damage the circuit, so as to ensure the stability of the main machine 1 and the precision of the galvanometer marking. The isolation cover 3 can be made of 304 stainless steel, which has good isolation effect.
[0061] As shown in the drawings, Figure 1 and Figure 8 As shown in the drawings, the isolation cover 3 has a wiring hole 31 and a avoiding hole 32, and the cable on the main machine 1 can pass through the wiring hole 31 to be connected to the galvanometer assembly 22, and the convex shaft 23 on the swing seat 2 can pass through the avoiding hole 32 to be connected to the main machine 1. The wiring hole 31 facilitates the cable to pass through and connect the galvanometer assembly 22, which not only ensures smooth connection of the line, but also avoids damage of the exposed cable. The avoiding hole 32 can make the convex shaft 23 of the swing seat 2 pass through smoothly and be connected to the main machine 1, without affecting the rotation function of the swing seat 2. The isolation cover 3 is provided with a connecting hole 33, the inner wall of the accommodating groove 111 is provided with a threaded hole 1112, and the isolation cover 3 is connected to the inner wall of the accommodating groove 111 through a fastener. The fastener can be a screw. During assembly, the isolation cover 3 is installed first, the shank of the screw is sequentially threaded through the connecting hole 33 and connected to the threaded hole 1112, and the cap of the screw is limited in the isolation cover 3. Then the swing seat 2 is installed.
[0062] In a possible implementation, as shown in the drawings, Figure 9 As shown in the drawings, the lens embedded type integrated laser marking machine comprises a refractive lens 4, which is arranged on the main machine 1 and located on the light path of the laser generator, so as to reflect the light wave to the light inlet 21, ensure the coherence and controllable direction of the light path transmission, and ensure the transmission efficiency of the laser.
[0063] In one possible implementation, as shown in Figure 9 The laser marking machine includes a beam expander 5 arranged in the main body 1 between the laser generator and the refractive lens 4. The light wave emitted by the laser generator first enters the beam expander 5, and then is concentrated and optimized by the beam expander 5, and is directed to the refractive lens 4. Under the action of the refractive lens 4, the light wave is bent by 90 degrees, and then enters the galvanometer assembly 22, and is refracted again by the internal refractive lens 4. The light wave can be emitted in the vertical direction of the laser marking machine and reach the marked object. At the same time, the laser marking machine can adjust the light emission angle from the vertical direction to the horizontal direction by rotating the swing seat 2.
[0064] In one possible implementation, as shown in Figure 1 and Figure 2 The swing seat 2 has a plurality of outer surfaces, and at least part of the outer surfaces are flat surfaces. The flat surfaces can effectively reduce the size of the swing seat 2, so that the structure is more compact. At the same time, when the swing seat 2 is rotated to adjust the angle, the flat surfaces can avoid collision and interference with the isolation cover 3, the cable or other components, so as to ensure the smoothness of the swing adjustment and provide a stable structural basis for multi-angle marking.
