Description

Technical Field

[0001] This utility model relates to the field of laser dimming equipment technology, and in particular to a high-precision visual dimming device. Background Technology

[0002] Laser equipment is now widely used in various precision manufacturing industries. The adjustment of the external optical path directly affects the final processing accuracy and effect. Therefore, the accuracy of external optical path adjustment is crucial for laser equipment, necessitating the design of a dedicated dimming device to assist technicians in quickly and accurately adjusting the external optical path. External optical path adjustment for laser equipment mainly falls into two categories: the first is for flying or fixed return optical paths, requiring the dimming device to ensure the laser is horizontal and enters the galvanometer from the center of the entrance aperture; the second is to ensure the laser emitted from the galvanometer exits vertically downwards from the center of the exit aperture. Existing dimming devices all require visual judgment of laser position deviation. The quality of external optical path adjustment depends entirely on the technician's skill and experience, compromising the consistency and stability of the equipment's processing results and hindering mass production.

[0003] The main purpose of this invention is to provide a high-precision camera dimming device, which aims to solve the problems of insufficient precision of existing auxiliary optical path adjustment equipment and the need for the camera to replace the human eye. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figure 1-4This utility model provides a high-precision visual dimming device, comprising:

[0031] Mounting plate I1 is used to mount galvanometers and lenses, and mounting holes are provided on mounting plate I1.

[0032] Mounting plate II2 is positioned opposite to mounting plate I1. Mounting plate II2 has a through groove that corresponds to the mounting hole.

[0033] A guide assembly is disposed between mounting plate I1 and mounting plate II2, with mounting plate I1 fixed to the guide assembly and mounting plate II2 slidingly engaged with the guide assembly.

[0034] A distance adjustment assembly is installed at one end of the guide assembly and is used to adjust the distance between mounting plate I1 and mounting plate II2.

[0035] Camera 3 is fixed on mounting plate II2, and the lens barrel of camera 3 passes through the through groove;

[0036] Cross ring 4, which is installed in the mounting hole;

[0037] The terminal system is connected to camera 3;

[0038] The galvanometer is mounted on the mounting plate I1 via a reflector mount.

[0039] The guide assembly is used to guide the mounting plate II2, and the distance adjustment assembly is used to adjust the straight-line distance between the mounting plate I1 and the mounting plate II2.

[0040] When this utility model is in operation, the galvanometer is mounted on the dimming device through the reflector mount, and the lens is directly fixed on the mounting plate I1. After removing the galvanometer, the dimming tool is screwed into the corresponding position. The communication cable and power cable of the camera 3 are connected, the spot analyzer software is opened, and the straight-line distance between the mounting plate I1 and the mounting plate II2 is adjusted by adjusting the distance adjustment component. The dimming is adjusted according to the change in the position of the spot when it is in different positions until the spot is displayed in the same position in the field of view when it is moved to any position, which indicates that the dimming is qualified.

[0041] This invention achieves the adjustment of the distance between two mounting plates through a guide component and a distance adjustment component, and improves the dimming accuracy by cooperating with the camera 3 and the terminal system.

[0042] The scheme is further optimized. The guide component includes guide rods 5. Several groups of guide rods 5 are set. Several guide rods 5 are fixed at equal intervals around one side of the mounting plate I1. Several sliding holes are opened on the mounting plate II2. Several guide rods 5 are arranged one-to-one with several sliding holes. The guide rods are inserted into the sliding holes. A linear bearing 6 is installed at the top of the sliding hole. The guide rods are inserted into the linear bearing 6 and slide with the axis bearing.

[0043] Multiple sets of guide rods 5 are arranged at equal intervals around the circumference to ensure uniform force on the mounting plate II2. The sliding fit between the linear bearing 6 and the guide rod (such as using a ball linear bearing 6) achieves low friction and high linearity movement (straightness error <0.5μm / 100mm).

[0044] The mounting plate uses a low thermal expansion material (such as Invar), and is equipped with an active temperature control system (such as a TEC module) to suppress optical path drift caused by temperature fluctuations. The high-precision fit between the guide rod 5 and the sliding hole (such as H7 / g6 tolerance grade) further reduces mechanical deformation.

[0045] Multiple guide rods 5, in conjunction with linear bearings 6, enable smooth linear movement of mounting plate II 2; threaded adjusting nuts 7 provide nanometer-level pitch adjustment to meet ultra-precision machining requirements.

[0046] The solution is further optimized by including an adjusting nut 7, which is rotatably connected to the top of the linear bearing 6, and is threadedly connected to the guide rod.

[0047] To further optimize the design, a camera connector 8 is detachably connected to the lens barrel of camera 3. An annular groove is provided inside the bottom of the camera connector 8. An attenuator 9 and a pressure plate 10 are provided in the annular groove. The pressure plate 10 is threaded into the annular groove and abuts against the attenuator 9.

[0048] Camera 3 is fixed to mounting plate II2 by mounting base 12, and lens barrel passes through through slot and is aligned with the center of optical path. Attenuator 9 is installed in the annular groove at the bottom of camera connector 8. The thickness of attenuator 9 is adjusted by the thread of pressure plate 10 to control the amount of light entering camera 3 and avoid overexposure or underexposure.

[0049] The design is further optimized by adding a cross pressure ring 11 to the through hole with an internal thread connection, which abuts against the cross ring 4.

[0050] The cross ring 4 is pressed tightly into the mounting hole by the cross pressure ring 11, forming a high-contrast reference mark. The terminal system extracts the center coordinates of the cross ring 4 through image processing algorithms (such as edge detection), registers them with the galvanometer scanning coordinate system, and eliminates mechanical installation errors.

[0051] The design was further optimized so that a mounting base 12 was fixedly connected to the side of mounting plate II2 away from mounting plate I1, and camera 3 was fixed on the mounting base 12.
