Fig. 1 is a plan view of a factory floor equipped with a laser cleaning device 100 having a dust removing device 104, and fig. 2 is a perspective view of an embodiment of the laser cleaning device 100. The laser cleaning apparatus 100 including the dust removing device 104 of the present embodiment will be described below as an example. In the present embodiment, the workpiece 105 to be cleaned by the laser cleaning apparatus 100 is not particularly limited, and may be any workpiece that can be cleaned by a laser.

Referring to fig. 1 and 2, the laser cleaning apparatus 100 includes: a base 101, a robot hand 102, a laser cleaning head 103, and a dust removing device 104. Wherein the base 101 supports a workpiece 105. The hand unit 102 is provided on the base 101. The laser cleaning head 103 performs laser cleaning of the workpiece 105. The laser cleaning head 103 is provided at the tip of the robot part 102 and is driven by the robot part 102. The dust removing device 104 is provided at the laser emitting end 103a of the laser cleaning head 103, and removes dust from a cleaning layer of the workpiece 105 cleaned by the laser cleaning head 103.

The laser cleaning apparatus 100 according to the present embodiment may be disposed in a factory workshop, for example, on the downstream side of the production line 200, and may be docked by, for example, the AGV cart 300. Specifically, for example, at the downstream side of the production line 200, a relay flow line 201 for carrying the workpiece 105 is provided, and the AGV car 300 drives the material car to be butted against the relay flow line 201 to transfer the workpiece 105. Correspondingly, the base 101 may be provided with a transfer device 106 such as a belt line or a conveyor chain, which is butted against the workpiece 105 conveyed by the AGV 300.

In some embodiments, the robot section 102 is gantry-shaped. The robot section 102 may include, for example: two mutually parallel Y-axis robots 107, X-axis robots 108, and Z-axis robots 109. The Y-axis robot 107 is attached to both sides of the base 101 in the X-axis direction. Both ends of the X-axis robot 108 in the X-axis direction are mounted on the Y-axis robot 107. The Z-axis robot 109 is mounted on the X-axis robot 108. The laser cleaning head 103 is mounted on the Z-axis robot 109. As the Y-axis robot 107, the X-axis robot 108, and the Z-axis robot 109, a slide table module driven by a motor can be used. The laser cleaning head 103 may use, for example, a known laser for laser cleaning.

Since the laser cleaning apparatus 100 is disposed in a factory workshop, it is necessary to improve the dust removal efficiency of the laser cleaning apparatus 100 as much as possible. Specifically, in the laser cleaning apparatus 100 of the present embodiment, since the dust removing device 104 described below is used, dust generated on the surface of the workpiece 105 during laser cleaning can be effectively removed.

Fig. 3 is a schematic view of the laser cleaning head 103 and the dust removing device 104, and fig. 4 is a schematic cross-sectional view of an embodiment of the dust removing device 104. Referring to fig. 4, with additional reference to fig. 3, in some embodiments, the dust removing device 104 includes a dust removing sleeve 112, the dust removing sleeve 112 is, for example, cylindrical, and the dust removing sleeve 112 is installed at one side of the laser emitting end 103a and may be coaxial with the laser emitting end 103 a. The manner in which the dust removing sleeve 112 is mounted on one side of the laser emitting end 103a is not particularly limited, and may be detachably and adjustably mounted in its axial direction on the laser emitting end 103a (e.g., the position of the field lens) of the laser cleaning head 103 by means of an adjustable mounting bracket (not shown), for example.

In some embodiments, in order to effectively clean the dust cleaned by the laser cleaning head 103, the lower portion of the dust removing sleeve 112 is formed with an annular air blowing chamber 114, such as a ring shape, and an annular first adsorption chamber 115, such as a ring shape. Specifically, for example, a first wall portion 116 may be provided by welding or the like on the inner side of the lower portion of the dust removing sleeve 112, and a cavity as the blow chamber 114 is formed between the first wall portion 116 and the inner side wall of the dust removing sleeve 112. An air inlet hole 117 for installing an air inlet joint is formed on the outer side of the dust removing sleeve 112, and the air inlet hole 117 is arranged above the dust removing sleeve 112 along the axial direction and is communicated with the air blowing cavity 114. Further, a second wall portion 118 may be provided outside the lower portion of the dust removing sleeve 112 by welding or the like, and a cavity as the first adsorption chamber 115 is formed between the second wall portion 118 and the outer side wall of the dust removing sleeve 112. The second wall portion 118 may be opened with a negative pressure generating hole 119 for communicating with, for example, a negative pressure pump for dust removal (not shown), and the negative pressure generating hole 119 may communicate with the first adsorption chamber 115. The first adsorption chamber 115 is disposed below the dusting sleeve 112 in comparison to the blowing chamber 114. Therefore, the blowing range of the blowing chamber 114 covers the emission range of the laser emission end 103a, and it can be ensured that the high-pressure gas blown out from the blowing chamber 114 can effectively blow up the dust of the workpiece 105 after the laser cleaning is completed. Further, since the annular first adsorption chamber 115 is formed at the lower portion of the dust removing sleeve 112, the dust lifted up can be adsorbed in time, thereby preventing the dust from polluting the workshop.

In some embodiments, to further improve the adsorption efficiency of the first adsorption chamber 115, the first adsorption chamber 115 surrounds the outside of the blowing chamber 114. As described above, by forming the air blowing chamber 114 between the first wall portion 116 located on the inner side of the dust removing sleeve 112 and the inner side of the dust removing sleeve 112, and forming the first adsorption chamber 115 between the second wall portion 118 located on the outer side of the dust removing sleeve 112 and the outer side of the dust removing sleeve 112, the first adsorption chamber 115 can be made to surround the outer side of the air blowing chamber 114. Therefore, the dust raised by the high-pressure gas of the blowing chamber 114 can be prevented from floating out of the dust removing sleeve 112, the adsorption efficiency of the first adsorption chamber 115 is improved, and the workshop is prevented from being polluted by the dust.

In some embodiments, the first adsorption chamber 115 is provided with a plurality of negative pressure generating holes 119 in a circumferential direction. Specifically, the negative pressure generating hole 119 is opened in the second wall portion 118 and communicates with the first adsorption chamber 115. The negative pressure generating holes 119 are, for example, two and are distributed at an interval of 180 degrees along the circumferential direction of the first adsorption chamber 115. In addition, the negative pressure generating holes 119 may further include, for example, 3 to 5, which are uniformly distributed along the circumferential direction of the first adsorption chamber 115. In addition, the negative pressure generating holes 119 may be communicated with one negative pressure pump or independent negative pressure pumps, respectively. This can further improve the adsorption efficiency of the first adsorption chamber 115, and prevent dust from escaping beyond the dust removal sleeve 112.

In some embodiments, to further improve cleaning efficiency, the duster 104 further comprises a brush head 120, the brush head 120 being mounted to a lower portion of the duster sleeve 112. In particular, a brush head 120 may be mounted to the lower portion of the second wall portion 118, for example, the brush head 120 surrounding at least a portion of the outside of the first adsorption chamber 115. Accordingly, the brush head 120 moves along with the movement of the laser cleaning head 103, thereby cleaning the dust on the workpiece 105, raising the dust, and sucking the dust through the first adsorption chamber 115. The brush head 120 may be made of a soft material, for example, and the brush head 120 may be provided to raise dust remaining at corners, gaps, and the like of the workpiece 105 and firmly adhering to the surface of the workpiece 105, thereby improving the efficiency and quality of cleaning.

FIG. 5 is a schematic cross-sectional view of another embodiment of the dust extraction device 104. Referring to fig. 5 and with additional reference to fig. 3, in some embodiments, the brush head 120 is, for example, annular and circumferentially surrounds the entirety of the outside of the first adsorption chamber 115. The lower part of the dust removing sleeve 112 forms an annular second adsorption cavity 121, the second adsorption cavity 121 is arranged outside the first adsorption cavity 115, and the brush head 120 is arranged between the first adsorption cavity 115 and the second adsorption cavity 121. Specifically, for example, a third wall portion 122 is provided on the outer side of the second wall portion 118, for example, by welding, and a cavity as the second adsorption chamber 121 is formed between the third wall portion 122 and the second wall portion 118. The brush head 120 may be mounted to the lower portion of the second wall portion 118, for example, by screwing, gluing, or the like. While the dust remaining on the corners, gaps, etc. of the workpiece 105 is swept up by the brush head 120, the dust remaining on the outside of the brush head 120 is also swept up, and in this embodiment, the second adsorption chamber 121 is provided on the outside of the brush head 120, so that the dust swept up by the outside portion of the brush head 120 can be effectively cleaned. This prevents a small amount of dust remaining outside the brush head 120 from escaping.

With continued reference to fig. 5, in some embodiments, the duster device 104 further comprises a hood 123, the hood 123 being disposed at a lower portion of the duster sleeve 112 and enclosing the brush head 120, the lower end of the brush head 120 protruding downward compared to the lower end of the hood 123. Specifically, the hood 123 may be, for example, surrounded on the outer side of the third wall 122, and since the lower end of the brush head 120 protrudes downward than the lower end of the hood 123, it is possible to ensure that the hood 123 does not collide with the workpiece 105 while the brush head 120 can brush the workpiece 105.

Although the above description has been made by taking the case where the brush head 120 has an annular shape, the present invention is not limited to this. The brush head 120 may also be C-shaped and circumferentially surround a portion of the outside of the first adsorption chamber 115. Specifically, the circumferential direction of the brush head 120 may be notched at 10 to 30 degrees. This allows dust and the like on the outside of the brush head 120 to be adsorbed by the first adsorption chamber 115.

Although the laser cleaning apparatus 100 in which the laser cleaning head 103 is disposed on the robot hand 102 has been described above as an example, the present invention is not limited to this. The laser cleaning apparatus 100 may be, for example, various hand-held laser cleaning apparatuses.
