[0039] Two rectangular slots are provided on one side of the main body 1 near the light outlet 27. A protective lens holder 9 and a focusing lens holder 10 are inserted into each of the slots. These holders are secured by a lens cover 8. These protect the focusing lens, ensuring its cleanliness and preventing damage, while also improving the stability of the optical path. When not in use, the lens cover 8 shields the light outlet 27, protecting the device from contamination.

[0040] The lower end of the main body 1 is provided with a wire groove 28, which is secured by a wire pressing plate 3. The lower end of the main body 1 is provided with an elliptical groove 29, which houses a switch button. The switch button is secured by a button cover 2. The laser cleaning safety lock comprises a cleaning plate 14, a petal 15, and a rotating disk 16. The main body 1 is provided with screw holes on the side. The cleaning plate 14 is fixed to the main body 1 by bolts. The cleaning plate 14 has a recessed hole, and the rotating disk 16 has a straight groove. The petal 15 is a pair of semicircular sealing plates. Each petal 15 has a protruding shaft on either side. The protruding shaft on one side of the petal 15 is secured in the recessed hole of the cleaning plate 14, while the protruding shaft on the other side of the petal 15 is secured in the straight groove of the rotating disk 16. The edge of the rotating disk 16 is provided with an arc-shaped through-hole for the screw to pass through. The lower end of the main body 1 is provided with two waterway ports, forming an internal circulating cooling water circuit. The air path interface is located between the two water path interfaces. The internal air path is in an inverted L-shape. The air path follows the optical path and comes out from the cleaning fixing plate 14 to blow away dust and debris on the lens.

[0041] The rotating disk 16 is provided with a notch, in which a magnet 33 is disposed. The main body 1 is also provided with a notch at a corresponding position, in which a sensor 32 is fixedly mounted.

[0042] The main body 1 has a rectangular groove on its side, in which a circuit board 31 is placed. A side cover A11 is provided on the side of the main body 1 near the rectangular groove, and the side cover A11 is fixedly connected to the main body 1 by bolts. The side cover A11 protects the circuit board 31 from damage.

[0043] The upper cover of the side cover A11 is provided with a side cover B12 , and an irregular circular groove 30 is provided in the middle of the side cover B12 . The side cover B12 is fixed to the knob screen 13 by bolts passing through the irregular circular groove 30 .

[0044] A fixed disk 17 is provided on one side of the rotating disk 16 away from the petals 15. The fixed disk 17 is connected to the rotating disk 16 by a screw passing through an arc-shaped through hole. After installation, the rotating disk 16 rotates, and the petals 15 are separated when the rotating disk 16 rotates clockwise and closed when it rotates counterclockwise.

[0045] During use, after the QBH connector 19 secures the laser head to the optical fiber head of the laser, a collimator is fixed above the collimator sleeve 18. The laser enters from the collimator, passes through the interior of the main body 1, and then the petal 15 is fully opened by the rotating disk 16. After the magnet 33 approaches the sensor 32, the sensor 32 outputs an electrical signal, allowing the laser to emit light, thus realizing the function of a safety lock to prevent accidents caused by accidental touch by the staff. By starting the first motor 6 and the second motor 7, the reflector 25 set on the motor shaft is appropriately adjusted to facilitate the reflection of the laser. At the same time, the device parameters of the laser head can be adjusted through the knob screen 13, and then the target object is laser cleaned through the light outlet 27.

[0046] Example 2

[0047] like Figures 1-12 As shown, this embodiment is based on the different aspects of the embodiment 1, and its details are as follows:

[0048] The safety lock for laser cleaning is replaced with a safety lock for laser welding. The safety lock for laser welding includes a welding fixing seat 20, a connecting seat 21, a limit block 22, a locking ring 23, a positioning seat 24 and a spring 34. The welding fixing seat 20 is fixed to the side of the main body 1 by bolts. The connecting seat 21 is sleeved on the welding fixing seat 20. A circular hole is provided in the middle of the limit block 22. The limit block 22 is square. A through hole is provided on the side of the limit block 22. The limit block 22 is sleeved on the connecting seat 21 through the circular hole. The limit block 22 is fixed to the welding fixing seat 20 by bolts passing through the through hole. A spring 34 is sleeved on the connecting seat 21. An external thread is provided on the connecting seat 21. The locking ring 23 and the positioning seat 24 are both provided with internal threads. The locking ring 23 and the positioning seat 24 are threadedly connected and fixed to the connecting seat 21 in sequence.

[0049] The welding fixing seat 20 is provided with a groove for fixing the sensor 32 , and the connecting block 21 is provided with a groove for fixing the magnet 33 .

[0050] The combination of a magnet and a Hall effect sensor provides a precise control mechanism, ensuring that the laser emits light only in the correct position and under the correct conditions. A Hall effect sensor is a magnetoelectric transducer device based on the Hall effect, capable of detecting changes in magnetic fields without physical contact. When a magnet approaches the Hall effect sensor, it senses the change in magnetic field and outputs a corresponding electrical signal.

[0051] During use, after the QBH connector 19 fixes the laser head to the optical fiber head of the laser, a collimator is fixed above the collimator sleeve 18. The laser enters from the collimator and passes through the inside of the main body 1. At this time, the locking ring 23 is rotated upward, the positioning seat 24 is pressed upward, the connecting seat 21 compresses the spring 34, close to the welding fixing seat 20, and the magnet 33 is close to the sensor 32. At this time, the laser is allowed to emit light, realizing the function of a safety lock to prevent the staff from accidentally touching the lens and causing an accident. By starting the first motor 6 and the second motor 7, the reflector 25 set on the motor shaft is appropriately adjusted to facilitate the reflection of the laser. At the same time, the device parameters of the laser head can be adjusted through the knob screen 13, and then the target object is laser cleaned through the light outlet 8.

[0052] Finally, it should be noted that the components involved in the present invention, such as the circuit board 31, collimating mirror, magnet 33, sensor 32, etc., are all universal standard parts or components known to those skilled in the art. Their structures and principles are known to those skilled in the art through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adapted controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the present invention. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in this field.

[0053] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
