Description
Technical Field
[0001] This utility model relates to the field of laser processing equipment technology, and in particular to a laser galvanometer protection device. Background Technology
[0002] In fields such as laser processing and laser scanning, laser galvanometers are core optical components, and their accuracy and stability directly affect the working performance of the equipment. However, in the existing technology, laser galvanometers often face problems such as dust accumulation, foreign matter intrusion, and accidental collisions when not in use. These factors can easily lead to contamination of the galvanometer lens and damage to the mechanical structure, thereby shortening the service life of the equipment and increasing maintenance costs.
[0003] Currently, some protective devices use fixed protective structures, which can provide a certain level of protection, but the protective components need to be manually disassembled when the galvanometer is used. This operation is cumbersome and time-consuming, making it difficult to meet the needs of efficient operation. Other foldable protective devices rely on manual opening and closing, which poses a risk that staff may forget to close them, resulting in a lack of protection. In addition, traditional protective devices lack intelligent timing reminder functions and cannot automatically prompt the protective plate to close according to the actual usage scenario of the galvanometer, further exacerbating the problem of protective failure caused by human negligence. Utility Model Content
[0004] This utility model relates to a laser galvanometer protection device, which solves the problems of some fixed protection devices requiring manual disassembly and operation being cumbersome, foldable devices relying on manual opening and closing being easily forgotten to close, and traditional devices lacking intelligent timing reminders, which can easily lead to protection failure due to negligence.
[0005] This utility model provides a laser galvanometer protective device, specifically including: a protective base, wherein a mating opening is formed at the center of the top surface of the protective base, penetrating its bottom surface; two rotating auxiliary seats are symmetrically arranged on the left side of the top surface of the protective base, and a rotating shaft is connected between the two rotating auxiliary seats; a protective plate is provided above the protective base, the left end of the protective plate adopts a semi-circular structure, and a shaft hole is formed at the axis of the protective plate relative to the semi-circular structure, the shaft hole being rotatably connected to the rotating shaft; when the bottom surface of the protective plate is in contact with the protective... When the top surfaces of the protective seats are in contact, the protective plates completely cover and block the mating opening. Two compression and storage slots are symmetrically arranged on the left side of the top surface of the protective seats. A limiting shaft is fixedly installed on the left side of the inner end of each of the two compression and storage slots, and a torsion spring is sleeved around each of the two limiting shafts. In its natural state, one torsion arm of the torsion spring contacts the bottom surface of the inner end of the compression and storage slot, and the other torsion arm contacts the bottom surface of the protective plate. At this time, the protective plate is in an unfolded state, with its bottom surface at a 90-degree angle to the top surface of the protective seat.
[0006] Furthermore, the protective base has a countersunk mounting hole extending through its bottom surface at each of the four corners adjacent to its top edge; the protective base contains a microcontroller and a timing module electrically connected to it, the timing value of which can be set as needed, and the protective base is powered by an external power source; a USB port is embedded on the left side of the top surface of the protective base and is electrically connected to the microcontroller; a buzzer is also installed on the left side of the top surface of the protective base and is electrically connected to the microcontroller.
[0007] Furthermore, a set of unfolding timing switches is fixedly installed in the middle of the left side of the top surface of the protective base. The unfolding timing switches are electrically connected to the microcontroller. The unfolding timing switches are tactile switches with the button facing upwards. When the unfolding timing switches are in the pressed start state, the unfolding timing switches provide feedback signals to the microcontroller, and the microcontroller controls the timing module to start. When the timing value of the timing module is reached, the timing module provides feedback signals to the microcontroller, and the microcontroller controls the buzzer to start.
[0008] Furthermore, a pressure plate is fixedly installed on the left side of the top surface of the protective plate; when the torsion spring is in its natural state, the left end of the pressure plate is in contact with the button end of the unfolding timer switch, at which time the unfolding timer switch is in the pressed start state.
[0009] Furthermore, a limiting slot with an arc-shaped groove structure is provided on the right end face of the protective plate; a connecting shaft is rotatably installed on the right side of the top surface of the protective seat via a bearing, and a limiting plate with a circular plate structure is fixedly installed on the top of the connecting shaft, with a cross section on the outer circumference of the limiting plate; when the bottom end face of the protective plate is in contact with the top surface of the protective seat, the limiting slot and the limiting plate are in the same position. If the cross section is not facing the limiting slot at this time, the limiting plate part of the structure is rotatably inserted into the limiting slot.
[0010] This utility model provides a laser galvanometer protection device, which has the following beneficial effects: When the laser galvanometer is not in use, the protective plate can be rotated and closed, with its bottom surface completely fitting against the top surface of the protective base, completely covering the mating opening and forming a physical barrier to fully enclose and protect the laser galvanometer. This effectively prevents damage to the laser galvanometer from dust, debris, or accidental collisions, extending the galvanometer's service life. When the protective plate is closed, rotating the limiting plate causes part of its structure to insert into the limiting slot, forming a mechanical lock to prevent the torsion spring from rebounding and causing the protective plate to automatically unfold, ensuring the reliability of the protective state and avoiding accidental opening when not in use. When the laser galvanometer is in use, simply rotating the limiting plate disengages it from the limiting slot, and the compressed torsion spring quickly rebounds, pushing the protective plate to automatically unfold to a vertical position around the pivot. No manual operation is required, improving ease of use and saving operation time.
[0011] When the protective plate of this utility model is unfolded, the pressure plate triggers the unfolding timing switch, and the microcontroller controls the timing module to start timing. The timing value can be preset according to the actual use requirements of the laser galvanometer. When the preset time is reached (i.e., the galvanometer is finished using), the buzzer will automatically start to remind the staff to close the protective plate, ensuring that the galvanometer is restored to the protective state in time when not in use, reducing the risk of protection failure due to negligence. The timing value of the timing module can be set through data connection with external devices via USB interface to adapt to the time requirements in different use scenarios, enhancing the flexibility and adaptability of the device.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0016] Example: Please refer to Figures 1 to 5 : This utility model proposes a laser galvanometer protective device, comprising: a protective base 1, with a mating opening 101 extending through its bottom end at the center of the top surface of the protective base 1; two rotating auxiliary seats 105 symmetrically arranged on the left side of the top surface of the protective base 1, the two rotating auxiliary seats 105 being connected by a rotating shaft 109; a protective plate 3 above the protective base 1, the left end of the protective plate 3 having a semi-circular structure, and a shaft hole 303 being formed at the axis of the semi-circular structure of the protective plate 3, the shaft hole 303 being rotatably connected to the rotating shaft 109; when the bottom end of the protective plate 3 is in contact with the top surface of the protective base 1, the protective plate 3 completely covers and blocks the mating opening 101; two compression storage grooves 103 symmetrically arranged on the left side of the top surface of the protective base 1, each compression storage groove 103 having a limiting shaft 108 fixedly installed on the left side of its inner end, the two... A torsion spring 104 is sleeved around each of the limiting shafts 108. In its natural state, one torsion arm of the torsion spring 104 contacts the bottom surface of the inner end of the compression storage groove 103, and the other torsion arm contacts the bottom surface of the protective plate 3. At this time, the protective plate 3 is in the unfolded state, and its bottom surface is set at a 90-degree angle to the top surface of the protective seat 1. A countersunk mounting hole 102 is opened at the four corners adjacent to the edge of the top surface of the protective seat 1, penetrating its bottom surface. The protective seat 1 is equipped with a microcontroller 1012 and a timing module 1011 electrically connected to it. The timing value of the timing module 1011 is set according to the requirements. The protective seat 1 is connected to an external power supply. A USB port 106 is embedded in the left side of the top surface of the protective seat 1 and is electrically connected to the microcontroller 1012. A buzzer 107 is also installed on the left side of the top surface of the protective seat 1 and is electrically connected to the microcontroller 1012.
[0017] In this embodiment, a set of unfolding timing switches 1010 is fixedly installed on the middle part of the left side of the top surface of the protective base 1. The unfolding timing switches 1010 are electrically connected to the microcontroller 1012. The unfolding timing switches 1010 are tactile switches, and the button end of the unfolding timing switches 1010 faces upward. When the unfolding timing switches 1010 are in the pressed start state, the unfolding timing switches 1010 send a feedback signal to the microcontroller 1012, and the microcontroller 1012 controls the timing module 1011 to start. When the timing value of the timing module 1011 is reached, the timing module 1011 sends a feedback signal to the microcontroller 1012, and the microcontroller 1012 controls the buzzer 107 to start. A pressure plate 302 is fixedly installed on the left side of the top surface of the protective plate 3. When twisted... When the force spring 104 is in its natural state, the left end face of the pressure plate 302 is in contact with the button end of the unfolding timer switch 1010, and the unfolding timer switch 1010 is in the pressed start state. The right end face of the protective plate 3 has a limiting slot 301 with an arc-shaped groove structure. A connecting shaft 202 is rotatably installed on the right side of the top surface of the protective seat 1 through a bearing. A limiting plate 2 with a circular plate structure is fixedly installed on the top of the connecting shaft 202. A section 201 is opened on the outer periphery of the limiting plate 2. When the bottom end face of the protective plate 3 is in contact with the top end face of the protective seat 1, the limiting slot 301 and the limiting plate 2 are in the same position. If the section 201 is not facing the limiting slot 301 at this time, part of the structure of the limiting plate 2 is rotatably inserted into the limiting slot 301.
[0018] The working principle of this embodiment: The protective base 1 is fixed to the equipment using fasteners (such as screws) through the countersunk mounting holes 102 at the four corners of the top surface, ensuring that the mating opening 101 is precisely aligned with the position of the laser galvanometer, so as not to affect the normal operation of the galvanometer; When the laser galvanometer is not in use, the protective plate 3 is in a rotated and closed state, with the bottom surface of the protective plate 3 completely in contact with the top surface of the protective seat 1. At this time, the protective plate 3 completely covers the mating opening 101, thus protecting the laser galvanometer. At this time, the torsion arm of the torsion spring 104 is compressed, storing elastic potential energy. In order to prevent the protective plate 3 from automatically unfolding, when the bottom surface of the protective plate 3 is completely in contact with the top surface of the protective seat 1, the limiting plate 2 can be rotated along the bearing so that the cross section 201 of the limiting plate 2 is not directly aligned with the limiting slot 301. Then, part of the structure of the limiting plate 2 will be inserted into the limiting slot 301, forming a mechanical limit and preventing the protective plate 3 from automatically unfolding. When the laser galvanometer is needed, the limiting plate 2 can be rotated along the bearing so that the cross section 201 of the limiting plate 2 is aligned with the limiting slot 301. At this time, the limiting plate 2 is completely disengaged from the limiting slot 301. Without the limiting slot 301 and the limiting plate 2 being inserted and limited, the compressed torsion spring 104 quickly rebounds, and its torsion arm pushes the bottom surface of the protective plate 3, causing the protective plate 3 to rotate upward about the pivot 109 and unfold at a ninety-degree angle with the top surface of the protective seat 1 (vertically upright), thereby exposing the mating opening 101. Furthermore, when the protective plate 3 is in the unfolded state (vertically upright), the pressure plate 302 presses against the button of the unfolding timing switch 1010, and the unfolding timing switch 1010 is in the pressed start state. It sends a start signal to the microcontroller 1012, and the microcontroller 1012 controls the timing module 1011 to start timing. The timing value of the timing module 1011 can be preset according to actual needs (based on the usage time of the laser galvanometer. The specific setting can be achieved by connecting to the USB port 106 for data connection). When the timing value of the timing module 1011 is reached (i.e., the laser galvanometer is used up), the timing module 1011 sends a feedback signal to the microcontroller 1012, and the microcontroller 1012 controls the buzzer 107 to start. The buzzer 107 reminds the staff to avoid forgetting to rotate and close the protective plate 3 again after the laser galvanometer is used up, ensuring that the laser galvanometer is always in a protected state when not in use.
