Description

Technical Field

[0001] This utility model relates to the field of laser marking machines, and in particular to a laser marking machine. Background Technology

[0002] A laser marking machine is a precision machining device that uses a high-energy-density laser beam to locally irradiate the surface of a workpiece, causing physical or chemical changes in the surface material to leave a permanent mark. It is widely used in various industries such as electronic components, medical devices, hardware tools, and food packaging to mark serial numbers, logos, production dates, and other information. It features clear, durable, non-contact, and highly efficient marking, making it an indispensable marking tool in modern manufacturing.

[0003] However, traditional marking machines have some significant shortcomings in practical use. Firstly, their continuity is poor. During workpiece loading, unloading, and marking, frequent manual intervention is often required, resulting in poor coordination between processes and low overall efficiency, failing to meet the demands of large-scale production. Secondly, during laser marking, the lack of effective light protection measures allows external light to easily interfere with the laser. Furthermore, the scattered light generated during laser marking can affect the operator's vision. More importantly, these light problems directly reduce the accuracy of laser marking, leading to inconsistent marking quality and impacting the overall product quality. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0024] Example: This example provides a laser marking machine, see [link to example]. Figure 1-5 Specifically, it includes a laser machine body 1, a gantry frame 11, and a clamping assembly 15 installed on the gantry frame 11. A protective box 14 is fixedly connected to the output end of the laser machine body 1. An opening and closing assembly 2 that can move up and down is provided at the opening of the protective box 14. A first guide rail 12 is fixedly provided on the outer wall of the laser machine body 1. A placement plate 13 is fixedly connected to the slider of the first guide rail 12. A positioning assembly 3 for fixing the workpiece is provided on the placement plate 13.

[0025] In this embodiment, the laser machine body 1 is the core of the entire equipment, used to generate laser light to process workpieces; the gantry frame 11 serves as a supporting structure, providing an installation position for the clamping assembly 15, allowing the clamping assembly 15 to move within a certain range; the clamping assembly 15 is used to clamp workpieces, realizing the loading and unloading operations of workpieces. The protective box 14 forms a sealed chamber, the core function of which is to isolate the interference of external ambient light on the laser marking process, while preventing internal laser scattering and ensuring operational safety; the clamping assembly 15, the opening and closing assembly 2, and the positioning assembly 3 are all connected to the PLC controller, and synchronous operation is achieved through controller control.

[0026] In the specific implementation process, such as Figure 3 and Figure 4 As shown, the opening and closing assembly 2 includes a baffle 21 that is slidably disposed at the opening of the protective box 14, an mounting plate 22 that is fixedly disposed on one side of the gantry frame 11, a first cylinder 23 that is fixedly disposed on the mounting plate 22, and the output end of the first cylinder 23 being fixedly connected to the outer wall of the baffle 21.

[0027] In this embodiment, when the placement plate 13 carrying the workpiece moves to the door of the protective box 14, the piston rod of the first cylinder 23 extends, pushing the baffle 21 upward to open the opening. After the workpiece enters, the cylinder piston rod retracts, pulling the baffle 21 downward to close the opening, thus forming a sealed marking environment. After marking is completed, the first cylinder 23 actuates again, opening the baffle 21 to allow the workpiece to be removed.

[0028] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the positioning component 3 includes a fixing frame 31 that can be detachably installed on the placement plate 13. Multiple adapter blocks 32 are arranged side by side on the upper surface of the fixing frame 31. Two protrusions 33 that fit against the outer wall of the workpiece are fixed in the inner cavity of the adapter block 32. A marking groove 34 is opened on the edge of the adapter block 32.

[0029] In this embodiment, the fixing frame 31 serves as an integral base and can be detached from the placement plate 13 for easy replacement or maintenance. The adapter block 32 is a modular fixture specifically designed according to the shape and size of the workpiece to be processed. Each adapter block 32 is responsible for fixing one workpiece, achieving precise workpiece positioning. The protrusion 33 is located within the cavity of the adapter block 32, and its shape matches the outer contour of the workpiece. By tightly fitting together, the workpiece's degrees of freedom are restricted, achieving precise mechanical positioning and preventing workpiece movement during marking. The marking groove 34 provides an unobstructed channel for the laser beam, ensuring that the laser accurately irradiates the specific location on the workpiece requiring marking, while avoiding accidental damage to the adapter block 32 itself.

[0030] In the specific implementation process, such as Figure 1 and Figure 5As shown, a second guide rail 4 is fixedly mounted on the upper surface of the gantry frame 11, a second cylinder 41 is fixedly mounted on the slider of the second guide rail 4, and a clamp 5 is installed at the output end of the second cylinder 41.

[0031] In this embodiment, the second guide rail 4 is mounted on the crossbeam of the gantry frame 11, enabling the entire clamping assembly 15 to move along the X-axis (horizontal direction) to cover the marking area and the loading / unloading area. The second cylinder 41 serves as the lifting drive source, controlling the clamping component 5 to move up and down along the Z-axis (vertical direction).

[0032] In the specific implementation process, such as Figure 1 and Figure 5 As shown, the clamping component 5 includes a support frame 51 fixedly installed at the output end of the second cylinder 41, and multiple pneumatic clamps 52 are installed side by side on the lower surface of the support frame 51.

[0033] In this embodiment, the support frame 51 is a crossbeam on which multiple pneumatic grippers 52 are mounted. The pneumatic grippers 52 are end effectors that directly perform gripping actions, controlling the opening and closing of the grippers by supplying / cutting off air, thereby clamping or releasing the workpiece.

[0034] In the specific implementation process, such as Figure 3 and Figure 4 As shown, a limiting guide rail 6 is fixedly provided on the outer wall of the laser machine body 1. The limiting guide rail 6 is arranged parallel to the first guide rail 12, and the lower surface of the placement plate 13 is slidably connected to the limiting guide rail 6. The main function of the limiting guide rail 6 is to provide additional support and guidance, and together with the first guide rail 12, it forms a stable double guide rail support system.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
