Description

Technical Field

[0001] The utility model relates to the technical field of laser marking machines, in particular to a high-precision laser marking machine. Background Technique

[0002] A laser marking machine is a device that uses a laser with a high energy density to irradiate the surface of a workpiece, causing physical or chemical changes in the material to form a permanent mark. Its functions mainly include adding identification information such as patterns, texts, serial numbers, and barcodes to products.

[0003] The camera in the laser marking machine is used for the positioning and feature recognition of the workpiece. If its position is inaccurate, it will cause the marking position to deviate from the target position, affecting the accuracy and quality of the marking effect. Existing marking machines can usually only roughly adjust the position of the camera, but cannot perform precise and detailed positioning, which also causes the laser marking machine to fail to meet the requirements of high-precision marking. Summary of the Utility Model

Unless otherwise specified, the meaning of "a plurality of" is two or more.

[0021] Unless otherwise clearly specified and defined, the terms "install", "connect", and "couple" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific circumstances.

[0022] As Figures 1 to 2 shown, a high-precision laser marking machine includes a frame 1 and a workbench 2 arranged on the top surface of the frame 1. The bottom of the marking machine in this embodiment is provided with a storage box for accommodating various items. An installation column 3 is fixedly connected to the top of the frame 1 by screwing. A laser 4 is screwed in the middle position of the installation column 3. The power and type of the laser 4 can be replaced according to the characteristics and requirements of the marking material. A galvanometer assembly 5 is fixedly connected to the side of the laser 4. The light incident end of the galvanometer assembly 5 is located on the optical path of the laser 4 and is used to adjust the deflection direction of the laser. A fine adjustment assembly 6 is movably connected to the top of the galvanometer assembly 5, and a camera 9 is fixedly connected to one side of the fine adjustment assembly 6.

[0023] Before the marking machine in this embodiment is used, first fix the camera 9 on the fine adjustment assembly 6. According to the image collected by the camera 9, adjust the position of the camera 9. If the position of the camera 9 cannot be accurately positioned on the workbench 2, the position of the camera 9 can be adjusted on the galvanometer assembly 5 so that it can be positioned on the workbench 2. Subsequently, the position of the camera 9 is finely adjusted through the fine adjustment assembly 6 so that the camera 9 can be accurately aligned with the position on the workpiece that needs to be marked, thereby improving the marking accuracy of the marking machine, and the adjustment method is simple and fast, which is convenient for users to operate.

[0024] As Figure 1As shown in the figure, the camera 9 of this embodiment is facing the top position of the galvanometer assembly 5. A reflecting mirror 7 inclined at 45 degrees along the laser light path direction is provided on one side of the light output end of the galvanometer assembly 5, and the camera 9 is located at the top of the reflected light path of the reflecting mirror 7. Through the above solution, while the reflecting mirror 7 deflects the light path, the processing position and shape of the product to be processed are captured and recognized by the camera 9, so that the marking machine can accurately mark the workpiece on the workbench 2. At the same time, the laser marking machine does not need to preset and adjust the workpiece position in advance, saving the manual operation time and fixture manufacturing cost in the manufacturing process, and improving the overall production efficiency and flexibility.

[0025] As Figure 1 shown, the galvanometer assembly 5 includes a galvanometer head 51, a fixing plate 52, and a mounting plate 53; the fixing plate 52 is fixedly connected to the top of the galvanometer head 51 and is provided with a through hole, and the reflecting mirror 7 is fixed to the bottom of the through hole and is located on one side of the galvanometer head 51; the mounting plate 53 is fixedly connected to the top position of the fixing plate 52 and is provided with a connection hole, and there is at least one connection hole. The fine adjustment component 6 is movably connected to the mounting plate 53 through the connection hole. The camera 9 of this embodiment passes through the through hole and then through the reflecting mirror 7 to capture the working condition of the surface of the workbench 2 downward, so that the marking machine can perform accurate positioning.

[0026] The connection hole of this embodiment is in a long strip shape, and the fine adjustment component 6 adjusts its position along the connection hole. The fine adjustment component 6 of this embodiment is fixed to the connection hole by screwing. When the position of the fine adjustment component 6 needs to be adjusted, loosen the screw and the fine adjustment component 6 can slide up and down in the connection hole until the camera 9 is in a suitable position, and then tighten the screw to fix the fine adjustment component 6. Through the above solution, the user can quickly adjust the position of the camera 9.

[0027] The mounting post 3 is provided with a reinforcing rib 8, and the laser 4 is fixedly connected to the top position of the reinforcing rib 8 to enhance the fixing strength of the laser 4.

[0028] As Figure 2 shown, the fine adjustment component 6 includes a fixed seat 61, an adjusting member 62, and a slider 63 movably connected to one side of the fixed seat 61; a fixed block is fixedly connected to one side of the fixed seat 61, and a fixed ring extends from one side of the fixed block; a contact block is fixedly connected to one side of the slider 63, and the contact block is located at the bottom position of the fixed ring; the adjusting member 62 is located in the fixed ring and abuts against the contact block at the bottom, and the adjusting member 62 is used to apply pressure to the contact block. The camera 9 of this embodiment is fixed to the other side of the slide away from the fixed seat 61. By applying pressure to the contact block by the adjusting member 62, the slider 63 moves downward along the fixed seat 61, and its moving amplitude is small, so as to realize fine adjustment of the position of the camera 9, realize accurate positioning, and improve the marking accuracy of the marking machine.

[0029] The above-described embodiments are only the preferred embodiments of the present utility model, and the protection scope of the present utility model cannot be limited thereby.
