Description

Technical Field

[0001] This utility model belongs to the field of laser cleaning technology, and in particular relates to a laser cleaning machine cleaning head with dustproof function. Background Technology

[0002] Laser cleaning technology refers to the process of using a high-energy laser beam to irradiate the surface of a workpiece, causing dirt, rust, or coatings to evaporate or peel off instantly. This high-speed and efficient removal of surface deposits or coatings achieves a clean finish. During the cleaning process, fumes and even flames are generated. To protect the environment, reduce harm to operators, and ensure continuous and normal cleaning operations, it is crucial to effectively collect fumes and suppress flames.

[0003] For example, Chinese patent CN 210023099 U discloses a laser cleaning machine with a dust suction function, including a laser cleaning head. One end of the laser cleaning head is provided with a dust suction pipe, which communicates with a dust suction channel located inside the laser cleaning head. The dust suction channel has multiple branch through holes on its wall, which communicate with the interior of the laser cleaning head.

[0004] The technical solution avoids pollution caused by smoke and dust. The suction channel and suction pipe allow for simultaneous laser cleaning and smoke collection. Furthermore, the suction pipe can freely extend, retract, and rotate, allowing for adjustment to align with the processing area according to application requirements, achieving rapid smoke and dust collection. Additionally, the connection between the suction channel and the galvanometer system provides cooling. Compared to traditional laser cleaning machines, this invention offers high dust collection efficiency, ease of use, and minimal environmental pollution, and can be used in enclosed working environments. However, if the suction power is insufficient, the vaporized smoke and dust will still disperse and adhere to the surface of the laser cleaning head. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a laser cleaning head with a dustproof function, thereby inhibiting the adhesion of vaporized dust to the laser cleaning head.

[0006] In view of this, the present invention provides a cleaning head for a laser cleaning machine with a dustproof function, including a laser emitting head. A support frame is fixedly installed on the outer surface of the laser emitting head, and an air ring is fixedly installed at the bottom end of the support frame. An air inlet pipe is connected to and passes through the outer wall of the air ring, and an air jet pipe is connected to and passes through the bottom end of the air ring.

[0007] Preferably, the air ring includes a fixed ring, a rotating ring is rotatably connected inside the fixed ring, a gear ring is fixedly installed on the outer ring of the bottom end of the rotating ring, a servo motor is fixedly installed on the support frame, a gear for driving the gear ring to rotate is fixedly installed on the output end of the servo motor, an air jet pipe is connected to and passes through the bottom of the rotating ring, and an air inlet pipe is connected to and passes through the fixed ring.

[0008] A support sleeve is fixedly installed on the outer side of the air ring. The support sleeve is sleeved on the outer ring of the gear rotating ring. The bottom end of the support sleeve is located below the gear ring. The servo motor is fixedly installed on the top of the support sleeve.

[0009] Preferably, the support sleeve is internally rotatably connected to a roller, which contacts the gear ring.

[0010] Preferably, a counterweight is fixedly installed at the top of the support sleeve, and the weight of the counterweight is the same as the weight of the servo motor.

[0011] Preferably, the jet pipe is tilted and points towards the center line of the laser emitter, and the end of the jet pipe away from the air ring is rotated at an acute angle with the center line of the jet pipe as the center.

[0012] Preferably, a bend joint is fixedly installed on the outer surface of the support frame. One end of the bend joint is provided with an air suction pipe, and the other end of the bend joint is connected to and passes through a shape-maintaining pipe. The other end of the shape-maintaining pipe away from the bend joint is connected to and passes through an air suction hopper.

[0013] The beneficial effects of this utility model are:

[0014] 1. The cleaning head of this laser cleaning machine with dustproof function supplies air into the air ring through the air inlet pipe and sprays it outward through the jet pipe at the bottom of the air ring. Since the jet pipe is pointed at the laser emitting head and rotated at an angle at the port, a downward blowing air band is formed at the jet pipe, that is, between the laser emitting head and the irradiated object. This allows the vaporized impurities to fall downward. At the same time, an air suction bucket and an air suction pipe connected to the air suction mechanism are set to suction air outward, so that the vaporized impurities can be moved away from the workpiece in time, avoiding the problem of vaporized impurities rising and adhering to the laser emitting head.

[0015] 2. The cleaning head of this laser cleaning machine with dustproof function has an inclined jet pipe that points to the center line of the laser emitting head. The end of the jet pipe away from the air ring rotates at an acute angle with the center line of the jet pipe as the center. This setting allows the high-speed airflow to blow out obliquely downwards and outwards, thus blowing out steam impurities. Attached Figure Description

[0022] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0023] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0024] This application discloses a cleaning head for a laser cleaning machine with dustproof function, including a laser emitting head 1. A support frame 2 is fixedly installed on the outer surface of the laser emitting head 1. An air ring 3 is fixedly installed at the bottom end of the support frame 2. An air inlet pipe 4 is connected to and passes through the outer side wall of the air ring 3. An air jet pipe 5 is connected to and passes through the bottom end of the air ring 3.

[0025] In one embodiment, the air ring 3 includes a fixed ring 301, a rotating ring 302 is rotatably connected inside the fixed ring 301, a gear ring 303 is fixedly installed on the outer ring of the bottom end of the rotating ring 302, a servo motor 304 is fixedly installed on the support frame 2, and a gear 305 that drives the gear ring 303 to rotate is fixedly installed on the output end of the servo motor 304. The jet pipe 5 is connected to and passes through the bottom of the rotating ring 302, and the air inlet pipe 4 is connected to and passes through the fixed ring 301. With this arrangement, the gear ring 303 can be driven to rotate, thereby enabling the jet pipe 5 to rotate, thereby rotating to form an airflow band to hinder the rise of vaporized impurities.

[0026] In one embodiment, a support sleeve 306 is fixedly installed on the outer side of the air ring 3. The support sleeve 306 is sleeved on the outer ring of the rotating ring 302 of the gear 305. The bottom end of the support sleeve 306 is located below the gear ring 303. The servo motor 304 is fixedly installed above the support sleeve 306. This arrangement can support the gear ring 303.

[0027] In one embodiment, a roller 307 is rotatably connected inside the support sleeve 306. There are multiple rollers 307 arranged in a circular array. The rollers 307 contact the toothed ring 303. This arrangement can limit the movement of the toothed ring 303.

[0028] In one embodiment, a counterweight 6 is fixedly installed at the top of the support sleeve 306. The weight of the counterweight 6 is the same as the weight of the servo motor 304. By setting the counterweight 6, the balance of the device can be ensured.

[0029] In one embodiment, the jet pipe 5 is tilted and points to the center line of the laser emitter 1. The end of the jet pipe 5 away from the air ring 3 is rotated at an acute angle with the center line of the jet pipe 5 as the center. This arrangement allows the high-speed airflow to blow out obliquely downwards and outwards, and also allows steam impurities to be blown outwards.

[0030] In one embodiment, a bend joint 7 is fixedly installed on the outer surface of the support frame 2. The bend joint 7 serves to change direction and diameter. One end of the bend joint 7 is provided with an air suction pipe 8, and the other end of the bend joint 7 is connected to and passes through a shape-maintaining pipe 9. The diameter of the air suction pipe 8 is larger than the diameter of the shape-maintaining pipe 9. The shape-maintaining pipe 9 can be adjusted to any position by deformation. The other end of the shape-maintaining pipe 9 away from the bend joint 7 is connected to and passes through an air suction hopper 10. The air suction hopper 10 forms a negative pressure by suction, which can accelerate the discharge of steam impurities.

[0031] In this embodiment, a laser cleaning head with a dustproof function is used. The laser emitting head 1 emits a laser to irradiate the object being cleaned. The surface of the irradiated object rapidly vaporizes at high temperature, completing the cleaning. The air inlet pipe 4 supplies air into the interior of the air ring 3 and sprays it outward through the jet pipe 5 at the bottom of the air ring 3. Since the jet pipe 5 points towards the laser emitting head 1 and rotates at an angle at the port, a downward blowing air band is formed at the jet pipe 5, that is, between the laser emitting head 1 and the irradiated object. This allows the vaporized impurities to fall downward. At the same time, an air suction bucket 10 and an air suction pipe 8 connected to the air suction mechanism are provided to suction air outward. This allows the vaporized impurities to move away from the workpiece in time, avoiding the problem of vaporized impurities rising and adhering to the laser emitting head 1.
