Description

Technical Field

[0001] The utility model relates to the technical field of laser cleaning guns, in particular to a laser single pendulum cleaning gun. Background Art

[0002] Laser rust removal is to use the laser beam emitted by a laser to hit the rusty material such as iron, and use high-intensity light beam and short-pulse laser to react with the light flow between the contamination layers to remove pollutants such as oxide layer (rust) on the surface of the material.

[0003] Since the laser cleaning gun emits a focused laser point when in use, that is, when the focus is on the surface of the object, the cleaning effect is best. However, during cleaning, the surface of many objects being cleaned is not a plane. When the hand is moved or the hand shakes, it is easy to cause the focus position to change, making it difficult for the staff to keep the cleaning gun at a reasonable and efficient distance for cleaning operations. Therefore, corresponding improvements are made to address this problem. Utility Model Content

[0004] Based on the technical problems existing in the prior art, the utility model proposes a laser single pendulum cleaning gun.

A second handle is fixed on the side below the first handle. The second handle is an L-shaped structure. A button switch is embedded on the surface of the second handle. Connect the fiber laser to the laser module, and then hold the first handle and the second handle with both hands respectively. Press the button switch, and the laser beam emitted by the fiber laser is directed to the reflective lens through the collimating lens. The reflective lens reflects the laser beam to the focusing lens, and the focusing lens focuses the laser beam to form a laser spot. At the same time, the output shaft of the galvanometer swing motor drives the mirror frame and the reflective lens to swing at a high frequency. The high-frequency moving laser spot eventually forms a laser line, and is emitted from the light outlet through the protective lens to the surface of the object to be cleaned to clean the dirt.

[0006] Preferably, a safety lock switch adjacent to the button switch is also embedded on the second handle. By setting the safety lock switch, it is possible to prevent the staff from accidentally touching the button switch and causing the cleaning gun to enter the working state. Only when the safety lock switch is turned on, the cleaning gun can start working by pressing the button switch.

[0007] Preferably, the light outlet is rotatably connected to a mirror cover that can be flipped upwards via a rotating shaft, so that dust can be prevented from entering the light outlet.

[0010] Preferably, a cooling chamber is provided inside the shell, and a cooling water inlet and a cooling water outlet communicating with the cooling chamber are fixed at the bottom of the shell. The cooling water inlet and the cooling water outlet are respectively connected to a water cooler through pipes. When working, the water cooler supplies water from the cooling water inlet and flows water back from the cooling water outlet, thereby cooling the interior of the cleaning gun, avoiding high-temperature operation of the cleaning gun, and extending its service life.

[0011] Preferably, the shell is provided with an air separation box at a position below the light outlet, the air separation box is located outside the light outlet in the extension direction, a plurality of evenly distributed air separation holes are provided on the top of the air separation box, an air cavity is provided in the shell, the air cavity has two air passages respectively communicating with the air separation box and the light outlet, an air inlet pipe communicating with the air cavity is installed on the lower surface of the shell, the air inlet pipe and the air compressor are connected through a pipeline, the air compressor introduces gas into the air inlet pipe through the pipeline, after entering the air cavity, the gas enters the air separation box and the light outlet from the two air passages respectively, the gas in the air separation box is blown upward from the air separation holes, the gas in the air outlet blows out from the light outlet the debris that will be adhered to the protective lens due to cleaning, thereby maintaining the cleanliness of the protective lens.

[0012] Preferably, a monitoring module is also provided on the shell, and the monitoring module is used to monitor the temperature of the collimating lens, the protective lens, the focusing lens and the reflecting lens. A sink groove is opened on the side of the shell, and a monitoring PCB board is fixed in the sink groove.

A cover plate for sealing the sink groove is fixed at the sink groove, and four lens alarm lights respectively used for corresponding temperature sensor alarm prompts are embedded on the cover plate. The temperature sensor monitors the temperature of the collimating lens, the protective lens, the focusing lens and the reflecting lens in real time. When the temperature of one or more of the collimating lens, the protective lens, the focusing lens and the reflecting lens reaches the set threshold, the corresponding lens alarm light will light up to alarm and remind the staff.

[0013] Preferably, the cover plate is also embedded with an external alarm light, and when the water level of the water cooler is insufficient or the air pressure alarm or the fiber laser alarm occurs, the external alarm light will light up to alert the staff.

[0014] Compared with the prior art, the utility model provides a laser single pendulum cleaning gun, which has the following beneficial effects:

[0015] 1. A laser single pendulum cleaning gun, by setting a first grip and a second grip, adopts a double grip structure, so that stable hand-held operation can be performed without easily causing shaking, thereby better controlling the distance, and the cleaning gun can support the use of KW laser guns, so that the cleaning effect is improved.

[0016] 2.

[0020] 6. A laser single-swing cleaning gun forms two-way gas protection through the design of the air blowing path on the light outlet side, avoiding the splashing of cleaning debris onto the protective lens, thereby increasing the service life of the protective lens.
