Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of laser processing technology. Specifically, it relates to a device for automatically identifying field lenses and configuring system parameters. Background Technology

[0002] Laser processing utilizes a laser beam of appropriate energy density, focused on the workpiece surface, to scan the target surface, causing physical or chemical changes in the material to achieve the processing objective. Typically, different wavelengths of laser light are selected to process the workpiece surface due to variations in workpiece material.

[0003] Laser processing equipment often requires field lenses that match different light transmission bands, and because the processing range varies, field lenses with different focal lengths are also needed. Therefore, to accommodate the diversity of workpiece materials and processing ranges, a single laser processing machine is often equipped with multiple field lenses. However, in the current process of changing field lenses, the laser processing equipment cannot automatically recognize the field lens parameters. Users need to possess certain professional knowledge to input the corresponding system parameters of the field lens into the laser processing equipment's software; otherwise, the equipment will not operate normally.

[0004] This application proposes a device for automatically identifying field lens information and setting system parameters that match the field lens during laser processing. This effectively reduces the professional requirements of laser processing equipment for users, improves the working efficiency of laser processing equipment, and avoids losses caused by parameter mismatch due to human factors. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a device for automatically identifying field lenses and configuring system parameters.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model discloses an automatic field lens identification and system parameter configuration device, comprising an identification contact module, a galvanometer assembly, a random field lens, and a main control board. The galvanometer assembly includes an X-galvanometer, a Y-galvanometer, and a galvanometer frame. The X-galvanometer and the Y-galvanometer are both disposed inside the galvanometer frame. The identification contact module is fixed to the side of the galvanometer frame and includes identification contact module A and identification contact module B. The random field lens is disposed on the front side of the galvanometer assembly.

[0008] As a preferred embodiment of this utility model, the input terminal of the main control board is communicatively connected to the output terminal of the identification contact module.

[0009] As a preferred technical solution of this utility model, the identification contact module A and the identification contact module B are provided with a mobile end, which is a protruding design and abuts against the random field lens.

[0010] As a preferred embodiment of this utility model, the random field lens is threadedly connected to the galvanometer assembly, and the random field lens has a protruding design.

[0011] As a preferred technical solution of this utility model, the random field lens includes a small focal length random field lens, a large focal length random field lens and a general field lens. The small focal length random field lens abuts against the recognition contact module A, the large focal length random field lens abuts against the recognition contact module B, and the general field lens is not connected to the recognition contact module.

[0012] As a preferred embodiment of this utility model, the X-mirror is vertically arranged inside the galvanometer frame, and the Y-mirror is horizontally arranged inside the galvanometer frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) Without changing the laser processing equipment usage process and user habits, this utility model adds an identification component that automatically identifies field lens information. After the user installs the field lens, the identification component can determine whether the field lens is a random accessory of this product.

[0015] (2) This utility model optimizes the system parameter setting logic of matching field lenses for laser processing equipment. After installing different field lenses, the working parameters of the laser processing equipment can be set according to the field lens information sent by the identification component. This reduces the error rate of manually reading field lens information and also achieves the purpose of quickly setting parameters to improve work efficiency.

[0016] (3) If the automatic identification lens component of this utility model determines that the lens is a random accessory, it calls the preset system parameters and makes appropriate modifications. If it determines that the lens is not a random accessory, it will prominently prompt the user to carefully check the lens information and leave a path for manually modifying the system parameters.

[0031] like Figure 1-8 As shown, this utility model provides an automatic field lens identification and system parameter configuration device, including an identification contact module, a galvanometer assembly 2, a random field lens 1, and a main control board 3. The galvanometer assembly 2 includes an X galvanometer 7, a Y galvanometer 8, and a galvanometer frame 6. The X galvanometer 7 and the Y galvanometer 8 are both disposed inside the galvanometer frame 6. The identification contact module is fixed to the side of the galvanometer frame 6. The identification contact module includes an identification contact module A 4 and an identification contact module B 5. The random field lens 1 is disposed on the front side of the galvanometer assembly 2.

[0032] Furthermore, in this embodiment, the input terminal of the main control board 3 is communicatively connected to the output terminal of the contact recognition module, so that the main control board 3 can receive signals from the contact recognition module.

[0033] Specifically, the main control board 3 is installed on the laser processing equipment near the galvanometer assembly 2. Based on the field lens information obtained from the identification contact module, the main control board 3 calls the pre-stored system working parameters and sends them to the host computer processing software to complete the parameter settings that match the installed field lens. The main control board 3 transmits electrical signals to the main control board 3 based on the pressing state received by the protruding part of the identification contact module. The main control board 3 also calls the working parameters of the corresponding field lens model pre-stored in the software to configure the parameters of the laser processing equipment based on its identification of the field lens model. When a non-random field lens 1 is identified, a prompt box will pop up to prompt the user to manually set the working parameters.

[0034] In this embodiment, identification contact module A4 and identification contact module B5 are provided with a movable end. The movable end has a protruding design and abuts against the random field lens 1. The identification contact module is used to identify the random matching field lens and the general field lens. Identification contact module A4 and identification contact module B5 are both fixed on the galvanometer assembly 2. The protruding part of the movable end extends out of the galvanometer assembly 2 and contacts the random field lens 1. The field lens will squeeze the protruding part of the contact module. The contact end of the identification contact module releases a conductive signal to the main control board 3. The main control board determines whether to obtain the field lens information based on whether different identification contact modules have released electrical signals.

[0035] In this embodiment, the random field lens 1 and the galvanometer assembly 2 are connected by a threaded connection. The random field lens 1 has a protruding design. After the random field lens 1 and the galvanometer assembly 2 are connected through the threaded interface, different contact states are generated with the recognition contact module according to different models of the random field lens 1. The protruding parts of different models of random field lenses 1 are different, resulting in the field lens contacting different recognition contact modules and triggering different electrical signals. The main control board 3 determines the model and other information of the random field lens 1 based on the contact state transmitted by the recognition contact module.

[0036] In this embodiment, the random field lens 1 includes a small focal length random field lens, a large focal length random field lens, and a general field lens. The small focal length random field lens abuts against the identification contact module A4, the large focal length random field lens abuts against the identification contact module B5, and the general field lens is not connected to the identification contact module. When the small focal length random field lens is installed on the galvanometer assembly 2, the identification contact module A4 will be triggered. When the large focal length random field lens is installed on the galvanometer assembly 2, the identification contact module B5 will be triggered. When the general field lens is installed on the galvanometer assembly 2, no identification contact module will be triggered. The main control board 3 calls the pre-stored system working parameters according to the electrical signal of the identification contact module triggered after the field lens is installed, and sends them to the working software of the laser processing equipment to complete the field lens parameter setting.

[0037] In this embodiment, the X-mirror 7 is vertically arranged inside the galvanometer frame 6, and the Y-mirror 8 is horizontally arranged inside the galvanometer frame 6. The galvanometer assembly 2 is used to change the two-dimensional spatial position of the laser on the working plane. The X-mirror 7 can rotate around its own motor axis to make the laser on the working plane achieve one-dimensional translation. The Y-mirror 8 can rotate around its own motor axis to make the laser on the working plane achieve one-dimensional translation in a direction perpendicular to the X-axis. The two orthogonal galvanometers work together to change the position of the laser on the working plane. The galvanometer assembly 2 serves as the mounting and fixing component for the identification contact module and the random field mirror 1, ensuring that the identification contact module and the random field mirror 1 can contact each other at a predetermined position.

[0038] Specifically, during operation, the user screws the field lens into the galvanometer assembly 2 via the threaded interface. If it is a field lens that comes with the equipment, the protruding part of the field lens will contact the identification contact module. Depending on the model of the field lens 1, the contact position of the identification contact module will be different, and the generated signal will also be different. If it is a field lens from another brand, it will not contact the identification contact module. Based on various different situations, the main control board 3 can determine the model of the field lens or whether it is a field lens from another brand, and set the working parameters of the processing equipment according to the judgment result to achieve the working state.
