[0024] Example 1 Please see Figure 1-2 This embodiment provides a safety blocking device for the light output port 61 of a laser 6. The device includes: an opening and closing actuator, a control circuit board 3, and a status monitoring module. The opening and closing actuator is disposed outside the light output port 61 of the laser 6 body. The opening and closing actuator includes a driving component and a blocking component fixed to the driving end of the driving component. The blocking component has a first station that completely covers the light output port 61 and a second station that completely avoids the light output port 61. The control circuit board 3 is integrated on the opening and closing actuator and electrically connected to the driving component. The control circuit board 3 drives the blocking component to switch between the first station and the second station. The status monitoring module is disposed corresponding to the blocking component and electrically connected to the control circuit board 3, and is used to monitor the switching status between the first station and the second station.

[0025] Specifically, this device is designed to ensure operator safety during laser equipment operation and effectively prevent injuries caused by accidental light emission. The device mainly includes an opening / closing actuator, a control circuit board 3, and a status monitoring module. The opening / closing actuator is installed outside the light emission port 61 of the laser body 6. Its structure includes a driving component and a blocking component fixedly connected to the output end of the driving component. The blocking component can switch positions under the control of the driving component, having two main positions: the first position is where the blocking component completely covers the light emission port 61, effectively blocking the laser beam; the second position is where the blocking component completely avoids the light emission port 61, allowing the laser to output normally. Furthermore, the control circuit board 3 is integrated into the opening / closing actuator and electrically connected to the driving component. It drives the blocking component to perform precise and reliable switching operations between the first and second positions through preset control logic signals to meet safety requirements in different usage scenarios. The status monitoring module monitors the position switching actions of the blocking component to ensure accurate switching between the first and second positions. This application achieves physical laser blocking by setting up an opening and closing actuator, provides electronic control logic by setting up a control circuit board 3, and ensures accurate state switching by setting up a status monitoring module. The three work closely together to achieve active safety management of the laser 6's output port 61. This design not only simplifies the structure and improves the system's compactness, but also significantly enhances the safety of the laser 6 during use, effectively addressing the risk of accidental light emission.

[0026] In one possible implementation, the driving component is a servo motor 1, and the device further includes: a mounting bracket 4, the housing of the servo motor 1 is fixed to a reference surface next to the light outlet 61 by the mounting bracket 4, the servo motor 1 is spaced apart from the reference surface, the rotation shaft of the servo motor 1 is set close to the reference surface and perpendicular to the reference surface, the shielding component is fixedly set on the rotation shaft of the servo motor 1, and the control circuit board 3 is fixedly connected to the mounting bracket 4.

[0027] Specifically, mounting bracket 4 refers to a structural component used to fix and support the micro servo motor 1. It can be configured as an L-shaped bracket with a through-hole area in the middle to avoid restricting the obstruction of components. Alternatively, it can be configured as follows: Figure 1 The irregular shape shown is for easy installation. The spacing between the servo motor 1 and the reference surface is to provide sufficient installation space for the servo motor 1's shaft and the shielding assembly, allowing the shielding assembly to be installed close to the reference surface.

[0028] As one feasible approach, a mounting plate can be set up according to actual needs. The mounting plate is detachably connected to the reference surface of the laser 6 by screws. At the same time, a through hole is opened on the mounting plate at the corresponding position of the light outlet 61. Then, the mounting bracket 4 can be fixedly installed on the mounting plate. By setting up the mounting plate, the overall structural layout can be better planned, providing a more solid support for the overall structure.

[0029] In one possible implementation, the blocking assembly includes: a fixing member 21 and a first baffle 22. The fixing member 21 is fixedly connected to the rotating shaft of the servo motor 1, and the first baffle 22 is fixed to the side edge of the fixing member 21. The rotating shaft of the servo motor 1 is perpendicular to the first baffle 22. The width of the first baffle 22 is greater than or equal to the width of the light outlet 61. The baffle has a first position that completely covers the light outlet 61 and a second position that completely avoids the light outlet 61.

[0030] Specifically, the width of the first baffle 22 is set to be greater than or equal to the width of the light outlet 61, ensuring that it can completely cover the light outlet 61 and eliminating the possibility of laser leakage. When the first baffle 22 is in the first position, it can completely block laser emission; when switched to the second position, it can completely avoid the light outlet 61, ensuring normal laser output. Controlling the rotation of the servo motor 1's shaft can correspondingly control the first baffle 22 to switch between the first and second positions.

[0031] In one possible implementation, the control circuit board 3 is provided with a circuit structure, which includes: a controller, a first power supply, a first resistor R1, a first capacitor C1, and a second capacitor C2; the motor drive terminal of the controller is connected to the control terminal of the servo motor 1; the first power supply is connected to the power supply terminal of the controller; one end of the first resistor R1 is connected to the positive power supply terminal of the servo motor 1, and the other end of the first resistor R1 is connected to the first power supply; one end of the first capacitor C1 is connected to the first power supply, and the other end of the first capacitor C1 is grounded; the second capacitor C2 is connected in parallel across the two ends of the first capacitor C1.

[0032] Specifically, this application limits current surges using a first resistor R1 and forms a multi-stage filter network using a first capacitor C1 and a second capacitor C2. This circuit structure achieves precise transmission of control signals for the servo motor 1 and provides anti-interference protection.

[0033] It is understood that the control circuit board 3 has a PCB board, on which the aforementioned controller, first power supply, first resistor R1, first capacitor C1 and second capacitor C2 are all arranged.

[0034] Furthermore, the supply voltage of the first power supply is 5V. By setting the supply voltage of the first power supply to 5V, the servo motor 1 can operate within the standard operating voltage range.

[0035] In one possible implementation, the shielding assembly further includes: a second baffle 23 and a third baffle 24, the second baffle 23 and the third baffle 24 being fixed at a preset angle to the side edge of the fixing member 21 and spaced apart from the first baffle 22, the first baffle 22, the second baffle 23 and the third baffle 24 being located on the same plane; The status monitoring module includes a mounting component 5, a photoelectric sensor, and a photoelectric detection circuit. The mounting component 5 is fixed on the control circuit board 3. The light source part and the light sensing part of the photoelectric sensor are arranged alternately on the mounting component 5, and a light blocking area is formed between the light source part and the light sensing part. The photoelectric detection circuit is arranged on the control circuit board 3 and is electrically connected to the light source part, the light sensing part, the first power supply, and the controller, respectively. When the first baffle 22 is located at the first work station, the second baffle 23 is located in the light blocking area; when the first baffle 22 is located at the second work station, the third baffle 24 is located in the light blocking area.

[0036] It can be understood that this preset angle is equivalent to the rotation angle of the first baffle 22 controlled by the servo motor 1 shaft from the first station to the second station. That is, when the first baffle 22 rotates from the first station to the second station, the second baffle 23 moves out of the light blocking area and the third baffle 24 rotates into the light blocking area, so as to block the light source part and the light sensing part of the photoelectric sensor again through the third baffle 24. And when the first baffle 22 is located in the first station, the center of the second baffle 23 is located in the center of the light blocking area; when the first baffle 22 is located in the second station, the center of the third baffle 24 is located in the center of the light blocking area.

[0037] In one possible implementation, the mounting component 5 may be configured to include a first mounting portion, a second mounting portion, and a connecting portion. The first mounting portion and the second mounting portion are respectively vertically fixed to both ends of the connecting portion and located on the same side of the connecting portion. The control circuit board 3 is set perpendicular to the reference plane. The connecting component is fixedly set on the side of the control circuit board 3 facing the mounting bracket 4. The light source portion of the photoelectric sensor is fixed to the center of the side of the first mounting portion near the second mounting portion. The light sensing portion of the photoelectric sensor is fixed to the center of the side of the second mounting portion near the first mounting portion. The first mounting portion, the second mounting portion, and the connecting portion together form a light blocking area.

[0038] Specifically, the first mounting part is a structural component for supporting the light source portion of the photoelectric sensor, and the second mounting part is a structural component for supporting the light sensing portion of the photoelectric sensor, both arranged parallel to the first mounting part. The connecting part is a rigid base connecting the first and second mounting parts to maintain the relative positional relationship between the two mounting parts. The light blocking area refers to the open space formed by the three components, and its detection sensitivity can be changed by adjusting the spacing between the mounting parts. Specifically, the spacing between the mounting parts can be slightly larger than the thickness of the second baffle 23 and the third baffle 24, so that the second baffle 23 and the third baffle 24 can be rotated into the light blocking area. The light source portion and the light sensing portion of the photoelectric sensor are respectively fixed to the opposite sides of the two mounting parts. This face-to-face mounting method, based on the parallel arrangement of the mounting parts, ensures that the light source and the sensor are facing each other and the spacing is constant. The design of the above-mentioned mounting component 5, in conjunction with the photoelectric sensor, ensures the reliability of the baffle position detection and realizes accurate monitoring of the opening and closing state of the laser 6's light outlet 61.

[0039] Furthermore, the dimensions of the second baffle 23 and the third baffle 24 are matched, the dimensions of the first mounting part or the second mounting part are matched, and the width of the second baffle 23 is greater than or equal to the dimension of the first mounting part.

[0040] Specifically, the above solution solves the key reliability problem in baffle position detection through precise size adaptation design. The size consistency of the second baffle 23 and the third baffle 24 ensures that the two baffles have the same blocking effect on the light path when they move into the light blocking area, avoiding fluctuations in the photoelectric sensor signal caused by size differences. When the second baffle 23 moves into the light blocking area, its width is sufficient to completely cover the light path, thereby reliably blocking the light according to the actual position of the baffle, enabling the photoelectric sensor to clearly output a blocking signal.

[0041] In one possible implementation, such as Figure 2 As shown, the photoelectric detection circuit includes: a second resistor R2, a third capacitor C3, a third resistor R3, and a fourth capacitor C4; one end of the second resistor R2 is connected to the positive terminal of the light source side of the photoelectric sensor U1, and the other end of the second resistor R2 is connected to the first power supply; one end of the third capacitor C3 is connected to the first power supply, and the other end of the third capacitor C3 is grounded; one end of the third resistor R3 is connected to the negative terminal of the sensing side of the photoelectric sensor U1 and the input terminal of the controller, respectively, and the other end of the third resistor R3 is connected to the first power supply; one end of the fourth capacitor C4 is connected to the positive terminal of the sensing side of the photoelectric sensor U1, and the other end of the fourth capacitor C4 is grounded; wherein, the negative terminals of the light source side and the negative terminals of the sensing side of the photoelectric sensor U1 are both grounded.

[0042] Specifically, by setting the above circuit structure, when the second baffle 23 or the third baffle 24 is in the light blocking area, the light source and the light sensing part are blocked, so that the light sensing part cannot sense the light signal, and thus the light sensing side is not conductive. At this time, the positive terminal of the light sensing side outputs a high-level signal to the controller under the action of the first power supply. When the second baffle 23 or the third baffle 24 moves out of the light blocking area, the light sensing part senses the light signal and thus conducts, and at the same time pulls down the level of the positive terminal of the light sensing side. At this time, the positive terminal of the light sensing side outputs a low-level signal to the controller. That is, it can be understood that when the servo motor 1 controls the first baffle 22 to move from the first station to the second station or from the second station to the first station, the controller receives the positive terminal of the light sensing side (attached) Figure 2 The level changes of the Feedback 1B terminal are all high-low-high level changes, which is used to monitor whether the first baffle 22 has moved to the corresponding station, and also significantly improves the reliability of the safe blocking of the laser 6 output port 61.

[0043] Example 2 This application embodiment also provides a laser device, including a laser 6 and a safety blocking device for the laser 6 output port 61 as described in any one of the embodiments. The safety blocking device is installed on the reference surface where the laser 6 output port 61 is located, so as to block and release the laser 6 output port 61 through the safety blocking device.

[0044] The specific structure of the safety blocking device at the laser 6 output port 61 in this embodiment has been described in detail in Embodiment 1, and its structural configuration will not be repeated here. By deploying an automated safety blocking device at the laser 6 output port 61, the risk of accidental light emission is effectively addressed, while the device can quickly switch between safety and functionality, thereby meeting the needs of the laser 6 in different operating states. This design not only improves the system's response speed but also enhances the safety of the laser 6 during use.
