when the lens 1111b needs to be cleaned, the rotating block 1111q is rotated, so that the output end of the air nozzle 1111t inclines upwards, under the action of the driving device 13, the air inlet is communicated with the first air outlet 111 through the air passage 121, the air compressor 1121 operates and conveys compressed air to the air inlet, the compressed air moves to the lens 1111b through the air nozzle 1111t and cleans dust on the lower side of the lens 1111b, the output end of the air nozzle 1111t faces the blade 1111n on the side, close to the rotating block 1111q, of the lens 1111b, under the action of the compressed air, the blade 1111n rotates, the blade 1111n drives the lens 1111b to rotate, and the lower side of the lens 1111b is cleaned.
A ball 1111r for reducing the rotational resistance of the lens 1111b is provided in the housing space 1111 m. The sliding pipe is in threaded connection with a fixing bolt 1111s, and the fixing bolt 1111s is abutted to the sliding pipe.
The working principle is as follows:
in the non-operating state, the air passage 121 and the first air inlet 112 are staggered, and the output end of the air tap 1111t is inclined downwards, as shown in fig. 1.
During cutting, the plate is placed to the lower side of the light outlet 1111c, and then the laser sequentially penetrates through the lens 1111b and the light outlet 1111c from top to bottom to cut the plate. When oxygen is needed as auxiliary gas during cutting, the gear 1131 moves to drive the rack 131 to move towards the first gas outlet 111 until the gas passage 121 is communicated with the corresponding first gas inlet 112, that is, the gas passage 121 is communicated with the oxygen cylinder 1122, see fig. 2. At this time, the oxygen is blown to the laser cutting point after passing through the first air inlet 112, the air passage 121, the first air outlet 111, the air outlet 1111, the air tap 1111t and the light outlet 1111c, so that the cutting speed is greatly increased. At this time, the lens 1111b can prevent the oxygen in the fixing tube 1111g from moving upwards, and the output end of the air tap 1111t is back to the lens 1111b, so that the vibration of the lens 1111b caused by the oxygen output from the air tap 1111t can be reduced, and the stability of the laser can be further improved.
In the present embodiment, the rack 131 can move only in the axial direction of the rack 131, and cannot rotate relative to the support plate 113. When air is required to be used as auxiliary gas, the servo motor 1312 operates, the rotating shaft 1311a rotates in the rotating groove 1311, so that the valve core 12 rotates in the valve body 11, the air passage 121 and the oxygen cylinder 1122 are disconnected until the air passage 121 is communicated with another first air inlet 112, that is, the air passage 121 is communicated with the air compressor 1121, at this time, the air compressor 1121 operates and outputs compressed air, and the compressed air sequentially passes through the first air inlet 112, the air passage 121, the first air outlet 111, the air outlet pipe 1111, the air nozzle 1111t and the light outlet port 1111c and then blows to a laser cutting point, as shown in fig. 3.
When dust on the lower side of the lens 1111b needs to be cleaned, the rotating block 1111q rotates 180 degrees, the output end of the air nozzle 1111t inclines upwards, the air compressor 1121 operates, the air nozzle 1111t outputs compressed air to the blade 1111n, and the compressed air drives the blade 1111n to rotate, so that the lens 1111b rotates, and the compressed air blows away the dust on the lower side of the lens 1111 b. At the time of cutting, the center of the lens 1111b is passed, so the center of the lens 1111b is the focus of cleaning. The air nozzles 1111t are inclined, so that compressed air output from the air nozzles 1111t is guided by the lens 1111b to move toward the central area of the lens 1111b, thereby cleaning dust in the central area of the lens 1111 b. And the rotation of the lens 1111b can make the dust in the central area of the lens 1111b be acted by the compressed air of different angles, thereby increasing the cleaning effect. See fig. 6.
When the lens needs to be replaced, the fixing bolt is unscrewed, the fixing bolt is separated from the sliding pipe, then the upward sliding pipe moves upwards, the sliding pipe is separated from the fixing pipe, after the lens is replaced, the sliding pipe moves downwards to be abutted against the fixing pipe again, and then the fixing bolt is screwed down.
It will be appreciated that modifications and variations are possible to those skilled in the art in light of the above teachings, and it is intended to cover all such modifications and variations as fall within the scope of the appended claims.
