Description

Technical Field

[0001] This utility model relates to the field of laser cleaning technology, specifically to a laser cleaning device. Background Technology

[0002] Laser cleaning is a surface cleaning method that uses laser technology. It removes dirt, oxides, coatings, and other impurities by irradiating the surface of the object being cleaned with a high-energy laser beam and utilizing the interaction between the laser and the surface. Laser cleaning is widely used in many fields, including industrial manufacturing, electronic equipment, aerospace, and cultural relic restoration.

[0003] Laser cleaning produces gases and fine particulate matter from the evaporation, decomposition, or stripping of impurities and contaminants caused by the interaction between the laser and the target surface. These impurities and contaminants may include grease, coatings, particles, dust, oxides, etc. To reduce the fumes generated during laser cleaning, vacuum cleaners, exhaust systems, and air filters are typically used to collect and filter the generated fumes.

[0004] However, existing vacuuming devices used in laser cleaning have shortcomings. For example, in a vacuuming mechanism and laser device disclosed in CN114160504A, the vacuum head housing is divided into multiple vacuum chambers by multiple obliquely arranged partitions. The vacuum hood is divided into multiple vacuum chambers by partitions, and these chambers need to distribute the suction volume evenly. However, because the obliquely arranged partitions cause the spatial layout of each vacuum chamber to be different, the distance from the suction pipe to the suction port is also different, resulting in different suction volume requirements and uneven suction distribution. Furthermore, the obliquely arranged partitions affect the direction and size of the corresponding suction pipe (transfer part) in each vacuum chamber, further hindering the uniformity of suction volume and affecting the cleaning effect. Based on these shortcomings, this application proposes a laser cleaning device that can evenly distribute the suction volume to solve the problem of uneven suction in existing devices. Utility Model Content

[0005] This invention proposes a laser cleaning device that solves the problems mentioned in the background section.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A laser cleaning device includes a worktable, a laser motion component mounted on the worktable, and a workpiece positioning platform located in front of the laser motion component. The worktable is equipped with a dust collection component, including a strip-shaped dust collection hood. The dust collection hood has a dust collection port on the side facing the workpiece positioning platform. The interior of the dust collection hood is divided into multiple dust collection chambers by multiple partitions. A smoke exhaust pipe is provided at the bottom of the dust collection hood corresponding to the position of the dust collection chamber. The smoke exhaust pipe is connected to a smoke purifier through a pipe.

[0008] Furthermore, the dust collection components are symmetrically arranged on both sides of the workpiece positioning table.

[0009] Furthermore, the inner side of the dust collection chamber is conical.

[0010] Furthermore, the laser motion assembly includes a three-axis slide and a laser cleaning head; wherein the three-axis slide is an electric slide in the X, Y, and Z axes.

[0011] Furthermore, the laser cleaning head includes a rectangular frame, which is fixedly sleeved on the end of the Z-axis electric slide. The side of the laser cleaning head is also equipped with a laser rangefinder and a laser thickness gauge.

[0012] Furthermore, it also includes a laser main unit and a cooling unit. The laser main unit is connected to the cooling unit through a pipe, and the laser cleaning working head is connected to the laser main unit through an optical fiber.

[0013] Furthermore, the workpiece positioning stage includes a vacuum suction tray and a ventilated tray; the vacuum suction tray is connected to an air storage tank through a pipe, and the ventilated tray is fixedly connected to the top of the vacuum suction tray, and the ventilated tray has several vent holes.

[0014] The beneficial effects of the technical solution provided in this application are as follows:

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1-4 A laser cleaning device includes a workbench 100, a laser motion component 200 disposed on the workbench 100, and a workpiece positioning stage 300 located in front of the laser motion component 200. The workbench 100 is provided with a dust collection component 400, including a strip-shaped dust collection hood 410. The dust collection hood 410 has a dust collection port 420 on the side facing the workpiece positioning stage 300. The interior of the dust collection hood 410 is divided into multiple dust collection chambers 440 by multiple partitions 430. The bottom of the dust collection hood 410 is provided with a smoke exhaust pipe 450 corresponding to the position of the dust collection chamber 440. The smoke exhaust pipe 450 is connected to a dust purifier 500 through a pipe.

[0024] The vacuum hood 400 is designed as a strip, and multiple partitions 430 are set in the vacuum hood 400 to divide it into multiple vacuum chambers 440. The multiple partitions 430 are set at equal intervals to ensure that each vacuum chamber 440 has the same air volume, thereby avoiding affecting the vacuuming effect. In addition, an exhaust pipe 450 is provided at the position of each vacuum chamber 440, which further shows that the suction force of each vacuum chamber 440 can be evenly distributed, and the suction pipes of multiple vacuum chambers 440 are not concentrated together, which can easily cause suction accumulation and affect the suction effect.

[0025] In some embodiments, the dust collection components 400 are symmetrically arranged on both sides of the workpiece positioning table 300. This symmetrical arrangement ensures that both sides of the workpiece positioning table 300 receive uniform dust collection. Regardless of which side of the workpiece is located on, the same suction power and cleaning effect can be obtained.

[0026] In some embodiments, the inner side of the suction chamber 440 is conical. The inner side of the suction chamber 440 is conical and gradually narrows. This design enhances suction, making it easier for smoke and dirt entering the suction chamber 440 to be drawn into the exhaust pipe 450. Furthermore, the conical design inside the suction chamber 440 also prevents smoke and dirt from accumulating inside, because dust and particles are less likely to remain on a slope than on a flat surface. That is, dust and particles will slide on the conical surface of the suction chamber 440 due to gravity, preventing accumulation inside the suction chamber 440.

[0027] In some embodiments, the laser motion assembly 200 includes a three-axis slide 210 and a laser cleaning head 220; wherein the three-axis slide 210 is an electrically driven slide in three directions: X, Y, and Z. The X-axis slide controls the horizontal movement of the laser cleaning head 220, the Y-axis slide controls the vertical movement of the head 220, and the Z-axis slide controls the depth movement of the head 220. This three-axis electrically driven slide design allows the laser cleaning head 220 to be precisely positioned and moved in three directions. Through the control of the three-axis slide 210, the laser cleaning head 220 can perform precise laser cleaning operations on the workpiece as needed. The electrically driven control of the three-axis slide makes the laser cleaning process more flexible and efficient, and can adapt to the cleaning of workpieces of different shapes and sizes.

[0028] In some embodiments, the laser cleaning head 220 includes a rectangular frame 221, which is fixedly fitted onto the end of the Z-axis electric slide. A laser rangefinder 222 and a laser thickness gauge 223 are also provided on the side of the laser cleaning head 220. The rectangular frame 221 acts as a connector, linking the laser cleaning head 220 to the end of the Z-axis electric slide, ensuring stable connection of the laser cleaning head 220 on the Z-axis electric slide. The laser rangefinder 222 is a non-contact measuring instrument that calculates the distance between the object being measured and the rangefinder by measuring the time difference after the laser beam is reflected. During the laser cleaning process, the laser rangefinder 222 can monitor the distance between the workpiece surface and the laser cleaning head 220 in real time and automatically adjust the position and cleaning parameters of the laser cleaning head based on the distance measurement results to ensure the stability and consistency of the cleaning effect. The laser thickness gauge 223 is an instrument used to measure the thickness of an object, also utilizing the principle of laser measurement. During the laser cleaning process, the laser thickness gauge 223 can monitor the thickness of the workpiece surface in real time and automatically adjust the cleaning parameters of the laser cleaning head according to the measurement results to meet the cleaning needs of workpiece surfaces of different thicknesses.

[0029] In some embodiments, the system also includes a laser host 700 and a cooler 800. The laser host 700 is connected to the cooler 800 via pipes, and the laser cleaning head 220 is connected to the laser host 700 via optical fiber. The laser host 700 is one of the core components of the laser cleaning system, responsible for generating a high-energy laser beam. It typically consists of a laser source, an optical system, and a power control system. The laser host 700 transmits the laser beam to the laser cleaning head 220 via optical fiber to perform the laser cleaning operation. To maintain the normal operation of the laser host 700, the cooler 800 serves to dissipate heat. The cooler 800 is connected to the laser host 700 via pipes, providing a cooling system. The laser host generates a large amount of heat during operation, and the cooler uses circulating water or other cooling media to reduce the temperature of the laser host, ensuring its stable operation.

[0030] In some embodiments, the workpiece positioning stage 300 includes a vacuum suction tray 310 and a ventilated support plate 320. The vacuum suction tray 310 is connected to the air storage tank 600 via a pipe, and the ventilated support plate 320 is fixedly connected to the top of the vacuum suction tray 310, and has several vent holes 321. The workpiece positioning stage 300 is mainly used to fix the workpiece and position it within the cleaning range of the laser cleaning head 220. The vacuum suction tray 310 firmly adheres to the workpiece by generating negative pressure, preventing it from moving or shaking. The ventilated support plate 320 supports the workpiece; when the workpiece surface contacts the vent holes 321, the suction force on the tray gradually decreases, thereby preventing damage to the workpiece. In addition, the vacuum suction tray 310 is connected to the air storage tank 600 via a pipe, providing the necessary negative pressure source. The air storage tank 600 can store sufficient compressed air, and when needed, the control system delivers negative pressure to the vacuum suction tray 310, enabling it to firmly adhere to the workpiece.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
