[0029] like Figure 1 As shown, the embodiment of the present application provides a laser cladding powder recovery device 100, which is mainly used to recover large-particle splash powder and small-particle smoke powder generated during laser cladding. The laser cladding powder recovery device 100 includes a first recovery mechanism 110 and a second recovery mechanism 120.
[0030] The first recovery mechanism 110 is used to recover the splashing powder, and includes a stage 111, and the stage 111 is provided with a processing table 1111. The recovery rate of the large-particle splashing powder generated during the laser cladding process is improved, and the cost is reduced.
[0031] The second recovery mechanism 120 is used to recover the smoke and dust powder. The second recovery mechanism 120 is connected to the first recovery mechanism 110. The second recovery mechanism 120 includes an air duct 121, a second recovery container 122 and a dust suction component 123. The dust suction component 123 is connected to the air duct 121. The air duct 121 has an air inlet end 1212 and an air outlet end 1213. The air inlet end 1212 is arranged toward the processing table, so that the dust suction component 123 sucks the smoke and dust on the processing table 1111 into the air duct 121. The air duct 121 is provided with a recovery port 1211, and the second recovery container 122 is arranged at the recovery port 1211. The smoke and dust gradually cool down in the air duct 121. At the same time, the smoke and dust powder in the air duct 121 gradually sinks under the action of gravity, and converges to the recovery port 1211 along the inner wall of the air duct 121, and is recovered by the second recovery container 122, thereby improving the recovery rate of small particles of smoke and dust powder generated during the laser cladding process and reducing costs.
[0032] In one embodiment, the stage 111 is provided with a hollow area 1112, which is connected to the collecting chamber 1121 of the support seat 112, and the hollow area 1112 is grid-shaped, and the aperture size of the grid holes of the hollow area 1112 is 5 to 20 mm.
[0033] In one embodiment, the first recovery mechanism 110 further includes a support seat 112 .
[0034] Optionally, the cross section of the support seat 112 is in a circular ring or square ring shape. At the same time, the support seat 112 is provided with a collection chamber 1121, a first port 1122 and a second port 1123, and the collection chamber 1121 is connected to the first port 1122 and the second port 1123. In this way, the support seat 112 is a hollow sealing structure with two ports, and the flying powder can only enter the collection chamber 1121 from the first port 1122 and then leave the collection chamber 1121 from the second port 1123, thereby preventing the flying powder from flying out of the support seat 112 and improving the recovery efficiency of the powder.
[0035] In this embodiment, the area of the first port 1122 is larger than the area of the second port 1123, the stage 111 is disposed at the first port 1122 of the support seat 112, and the processing table 1111 faces outward. By providing a large-area first port 1122 for mounting the stage 111, a larger moving space is provided for the continuous arm connected to the laser cladding device 200, and collision and interference between the laser cladding device 200 and the support seat 112 can be prevented.
[0036] In addition, the processing table 1111 of the stage 111 is disposed in the collecting chamber 1121. In this way, the stage 111 is sunken and disposed at the first port 1122 of the support seat 112, so that the outer periphery of the processing table 1111 forms a barrier to reduce the flying powder from the support seat 112.
[0037] In one embodiment, the projection of the first port 1122 and the projection of the second port 1123 at least partially overlap in a direction perpendicular to the processing table 1111. This can shorten the relative distance between the first port 1122 and the second port 1123 and accelerate the recovery of the flying powder.
[0038] In this embodiment, as a preference, the first port 1122 and the second port 1123 are arranged with their centers facing each other. In this way, the cross section of the support seat 112 is funnel-shaped. In the direction perpendicular to the processing table 1111, the projection of the second port 1123 is overlapped and arranged at the center of the projection of the first port 1122. In this way, the recovery speed of the flying powder can be accelerated, and the volume of the support seat 112 can be reduced.
[0039] In this embodiment, the first recovery device further includes a support 114 disposed in the collection chamber 1121, one end of the support 114 abuts against the side of the stage 111 away from the processing table 1111, and the other end is connected to the support seat 112. This makes the stage 111 more stable and facilitates laser cladding processing. Of course, in other embodiments, the support 114 can be removed according to the actual connection stability of the stage 111 and the support seat 112.
[0040] In this embodiment, the lower periphery of the air inlet end 1212 of the air duct 121 abuts against a partial edge of the outer side of the support seat 112, so that the air inlet end 1212 and the first port 1122 are connected, and the air inlet end 1212 of the air duct 121 faces the processing table 1111, and most of the smoke and dust generated during the laser cladding process is sucked into the air duct 121.
[0041] In one embodiment, the air inlet end 1212 of the air duct 121 is located above the processing table 1111. Specifically, the upper peripheral edge of the air inlet end 1212 of the air duct 121 is located above the processing table 1111. In this way, while the air inlet end 1212 of the air duct 121 faces the processing table 1111, the upper part of the air inlet end 1212 is higher than the stage 111 and the laser cladding device 200 during operation, so as to fully capture the smoke and powder on the processing table 1111, and also not interfere with the moving space of the robot 300 during operation.
[0042] In other embodiments, the air inlet end 1212 of the air duct 121 abuts against all edges of the outer side of the support seat 112, so that the air inlet end 1212 is connected to the first port 1122. At the same time, a through hole is provided at the air inlet end 1212 of the air duct 121 for the laser cladding device 200 and the mechanical receiver to pass through and move, and a flexible dust strip is provided at the through hole. In this way, the efficiency of dust recovery during the laser cladding process can be improved, but the structure of the air duct 121 is more complicated.
[0043] In one embodiment, the first recovery mechanism 110 further includes a first recovery container 113, which is disposed corresponding to the second port 1123, and the opening of the first recovery container 113 is sealed and connected to the support seat 112. In this way, foreign impurities are prevented from entering the first recovery container 113.
[0044] Exemplarily, the first recovery container 113 includes a neck cavity 1131 and an abdominal cavity 1132. The cross section of the neck cavity 1131 is the same as the shape of the second port 1123. The support seat 112 is embedded in the neck cavity 1131 to seal the first recovery container 113 and the support seat 112. The second port 1123 and the abdominal cavity 1132 are in communication.
[0045] Exemplarily, the support base 112 and the first recovery container 113 are detachably connected to facilitate emptying the first recovery container 113 .
[0046] Exemplarily, the first recovery container 113 is provided with a through hole, and a detachable sealing cover is disposed at the through hole to facilitate emptying the first recovery container 113 .
[0047] In one embodiment, the dust collection assembly 123 includes a fan 1231 , which is close to the air duct 121 and close to the air outlet end 1213 . The second recovery mechanism 120 also includes a filter 124 , which is arranged between the recovery port 1211 of the second recovery container 122 and the fan 1231 .
[0048] The filter element 124 is used to filter smoke and dust from the flowing gas in the air duct 121 .
[0049] The fan 1231 is used to generate suction to promote the smoke to flow from the air inlet end 1212 to the air outlet end 1213. The dust collection assembly 123 also includes a motor 1232, and the fan 1231 is electrically connected to the motor 1232, and the motor 1232 drives the fan 1231 to rotate.
[0050] In one embodiment, the air duct 121 includes a curved tube, and the recovery port 1211 is arranged on the outer arc side of the curved part of the air duct 121. In this way, the recovery port 1211 is located below the air duct 121. After the smoke enters the air duct 121, it gradually cools down. At the same time, the smoke powder in the air duct 121 gradually sinks under the action of gravity, and converges to the recovery port 1211 along the inner wall of the air duct 121, and is recovered by the second recovery container 122.
[0051] In one embodiment, the motor 1232 is disposed on the outer arc side of the bend of the air duct 121 and abuts against the air duct 121. Thus, when the motor 1232 is started, the fan 1231 can be driven to rotate, and the vibration of the motor 1232 itself can also be transmitted to the wall of the air duct 121 and the filter 124, so that the smoke and dust powder attached to the wall of the air duct 121 and the filter 124 can be accelerated to fall off and collected by the second recovery container 122.
[0052] In one embodiment, the second recovery container 122 is sealed and connected to the recovery port 1211 of the air duct 121 , so as to prevent foreign impurities from entering the second recovery container 122 .
[0053] Exemplarily, the air duct 121 and the second recovery container 122 are detachably connected to facilitate emptying the second recovery container 122 .
[0054] Exemplarily, the second recovery container 122 is provided with a through hole, and a detachable sealing cover is disposed at the through hole to facilitate emptying the second recovery container 122 .
[0055] In one embodiment, a first roller 115 is provided at the bottom of the first recovery container 113, and a second roller 125 is provided at the bottom of the second recovery container 122. This facilitates adjusting the relative position of the support base 112 and the air inlet end 1212 of the air duct 121, thereby improving the recovery efficiency of the smoke and dust powder.
[0056] In one embodiment, the first roller 115 and the second roller 125 can also be used to adjust the height, so as to facilitate the adjustment of the relative position of the support base 112 and the air inlet end 1212 of the air duct 121 .
