[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention provides a first wedge slidably disposed at the bottom of the laser marking head, and a reflection component is disposed on the first wedge and the mirror plate. A focusing bracket that can slide up and down is disposed at the bottom of the laser marking head, and a second wedge is fixedly disposed on the top of the focusing bracket. The upward displacement of the focusing bracket drives the top of the second wedge to press the first wedge upward to make the first wedge move horizontally. In the process of marking the upper surface of the sample, the focusing bracket is placed on the upper surface of the sample, which is the focal plane, and laser marking can be performed directly. When marking the side of the sample, the focusing bracket is placed on the upper surface of the sample, and then a force is applied downward to displace the focusing bracket upward, and the focusing bracket drives the second wedge on the top to displace upward, and the top of the second wedge presses the first wedge upward, so that the first wedge moves horizontally in the direction close to the light outlet, thereby moving the first reflector to the light outlet, and reflecting the laser to the side of the sample through the reflection component to complete the laser marking.

[0019] During the laser marking process, after marking the upper surface, there is no need to flip the sample. By pressing down the laser marking head, the first wedge and the second wedge cooperate to drive the first reflector to move to the light outlet, so that the marking laser is aimed at the side of the sample, thereby achieving fast and efficient front and side laser marking of the sample.

[0020] 2. In the present invention, the second reflector, the third reflector and the fourth reflector are fixed on the mirror plate. The first reflector reflects the laser emitted from the light outlet to the second reflector, and then reaches the side of the sample after being reflected by the third reflector and the fourth reflector. The other side of the mirror plate is fixed on the fine-tuning component, and the distance between the mirror plate and the side of the sample is adjusted by the fine-tuning component, so that the side of the sample is located on the focal plane of the laser marking head, thereby ensuring the effect of side laser marking.

[0021] The marking light in the direction of the mirror plate and the sample will be reflected by the first reflector and the fourth reflector. There is a double light path between the mirror plate and the sample. When the fine-tuning component is adjusted slightly, a double displacement focusing effect can be achieved. The adjustment sensitivity is high, the adjustment efficiency is improved, and the travel space of the fine-tuning component is saved.

[0022] 3. The fine-tuning assembly of the present invention comprises a first scissor-type link and a second scissor-type link connected by a pin between the back plate and the mirror plate, a transmission block is hingedly arranged at the end of the second scissor-type link, the transmission block is slidably installed inside the guide groove, a screw is threadedly arranged on the transmission block, and the opening distance of the scissor-type link is achieved by adjusting the screw, thereby adjusting the displacement of the mirror plate; two scissor-type links are used for adjustment to ensure the smoothness of the displacement, and the screw is used for operation to facilitate the control of the adjustment accuracy and achieve precise fine-tuning.

[0023] 4. The present invention provides a ratchet on the inner wall of a vertical groove, a corresponding oblique groove is provided inside the tenon, a reset groove is provided at the bottom end of the oblique groove, the reset groove passes through the top of the focusing bracket and communicates with the outside, a spring and a ratchet rod are installed inside the oblique groove, and a reset rod is provided on the ratchet rod. A through hole is provided at the inner bottom of the vertical groove, a second tension spring is provided inside the through hole, one end of the second tension spring is fixedly connected to the bottom of the tenon, and the other end of the second tension spring is fixedly connected to the bottom of the vertical rod.

[0024] The second tension spring exerts a downward force on the focus bracket.

[0061] The second tension spring 391 exerts a downward force on the focusing bracket 300. When the focusing bracket 300 is lifted upward, the ratchet rod 392 and the ratchet tooth 380 interact with each other and are in a locked state, so that the focusing bracket 300 is in a balanced position, which facilitates the smooth adjustment or marking work of the fine-tuning component 500.

[0062] Furthermore, the material of the reflector is silicon wafer.

[0063] It is worth mentioning that the material of the reflector is silicon wafer or optical glass such as BK7, and is coated with a reflective film layer suitable for a specific laser wavelength to ensure the high reflectivity of the reflector.

[0064] Furthermore, the reflection angle of the light emitted from the light outlet 110 on the reflector is 45 degrees.

[0065] It should be noted that after the laser from the light outlet 110 is reflected four times, it is ensured that the imaging of the laser on the side of the sample 150 after reflection remains the same.

[0066] The present invention illustrates the technical concept of the present invention through the above embodiments, but the present invention is not limited to the above embodiments, that is, it does not mean that the present invention must rely on the above embodiments to be implemented. Those skilled in the art should understand that the relevant improvements to the present invention fall within the protection scope and disclosure scope of the present invention.
