Description

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system.

[0041] A mounting ring 2115 is fixedly installed on the inner wall of the support column 2103, and the oxygen filter membrane 2117 is bonded to the top of the mounting ring 2115. A positioning ring 2116 is fixedly installed on the inner wall of the support column 2103, and the top of the positioning ring 2116 contacts the bottom of the cover plate 2118.

[0042] The surface of the support column 2103 is fixedly connected with a ventilation tube 2121, and the inner wall of the ventilation tube 2121 is fixedly installed with a valve 2122. By setting the ventilation tube 2121 and the valve 2122 for use together, when the air pressure inside the support column 2103 is too high, most of the nitrogen will open the valve 2122, allowing the nitrogen to enter the air again, thereby ensuring the stability of air filtration;

[0043] The adjustment mechanism 3 includes a fixing plate 301, which is fixedly mounted on one side of the adjustment seat 13, a second motor 302 is fixedly mounted on the inner wall of the fixing plate 301, a threaded rod 303 is fixedly mounted on the output end of the second motor 302, a threaded sleeve 304 is threadedly connected to the surface of the threaded rod 303, one side of the threaded sleeve 304 is fixedly mounted on one side of the support plate 2101, a bearing 305 is fixedly mounted on the surface of the threaded rod 303, and the bottom of the outer ring of the bearing 305 is fixedly mounted on the inner wall of the fixing plate 301;

[0044] A positioning column 306 is fixedly installed on one side of the adjustment seat 13, and a dovetail block 307 is fixedly installed on one side of the fixing plate 301. A dovetail groove 308 for use with the dovetail block 307 is opened on one side of the positioning column 306. By setting the dovetail block 307 and the dovetail groove 308 for use together, the support plate 2101 can drive the dovetail block 307 to move in the inner cavity of the dovetail groove 308 when moving, so that the support plate 2101 will not be deflected when moving, thereby ensuring the stability of the support plate 2101 when moving.

[0045] By setting up the oxygen enrichment unit 21 and the adjustment mechanism 3 for use in conjunction, the purpose of increasing the oxygen content when cutting the speaker raw materials can be achieved, avoiding the phenomenon of burrs on the raw materials due to unstable oxygen content at the cutting position, and also avoiding the phenomenon of residues on the raw materials after cutting. At the same time, it also ensures that the cut surface of the raw materials is smooth enough to ensure that subsequent processing is easier and the cutting effect is improved.

[0046] The specific implementation of this embodiment is as follows: when the user needs to cut the raw material of the speaker, the user places the raw material on the laser cutting machine body 11. At this time, the user uses the external control switch to control the position of the movable seat 12 and adjusts it to the origin. At this time, the user uses the external control switch and the adjustment seat 13 to move the position of the laser cutting head 14 and adjusts it to the required position. At this time, the user uses the external control switch and the power supply to start the second motor 302. The start of the second motor 302 drives the threaded rod 303 to rotate. The threaded rod 303 rotates through the bearing 305. The rotation of the threaded rod 303 drives the threaded sleeve 304 to move. The movement of the threaded sleeve 304 drives the threaded sleeve 304 to move. The support plate 2101 is moved, and the movement of the support plate 2101 drives the dovetail block 307 to move in the inner cavity of the dovetail groove 308, so that the support plate 2101 moves to a desired position. At this time, the user uses an external control switch and a power supply to start the fan 2102. The start of the fan 2102 draws the outside air into the corrugated hose 2104, and the air enters the inner cavity of the support column 2103 through the corrugated hose 2104. After entering the inner cavity of the support column 2103, the air is filtered through the oxygen filter membrane 2117, and most of the oxygen will enter the inner cavity of the gas collecting box 2105. At the same time, nitrogen and other gases will be due to the excessive air pressure inside the support column 2103, and the valve 2122 will be blown out. Open, and enter the air again through the position of valve 2122. After most of the oxygen enters the gas collecting box 2105, it enters the inner cavity of the exhaust pipe 2109 through the air hole 2110, and is finally discharged through the exhaust pipe 2109, so that the oxygen can be within the range of laser cutting, increasing the oxygen content at the laser cutting position. During the process of oxygen discharge, the user uses the external control switch and power supply to start the first motor 2106. The start of the first motor 2106 drives the half gear 2107 to rotate. The rotation of the half gear 2107 drives the rotating wheel 2108 to rotate through the tooth groove 2111. When the rotating wheel 2108 rotates, it drives the movable plate 2113 to squeeze the spring 2114. When the tooth groove 2111 is disengaged from the meshing, the reaction force of the spring 2114 causes the wheel 2108 to rotate to the initial position, and the oxygen can move downward in an S-shaped state when it is separated from the exhaust pipe 2109, so that the entire cutting area can be evenly filled. If the oxygen content needs to be adjusted, the power of the fan 2102 can be adjusted, thereby achieving the purpose of increasing the oxygen content when cutting the speaker raw material, avoiding the phenomenon of burrs on the raw material due to unstable oxygen content at the cutting position, and avoiding the phenomenon of residues on the raw material after cutting. At the same time, it also ensures that the cutting surface of the raw material is smooth enough to ensure that the subsequent processing is easier and the cutting effect is increased.

[0048] See also Figure 1-11The present invention provides a technical solution: a laser cutting machine for speaker production. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0049] As a further limitation of the auxiliary cutting mechanism 2 of the present invention, the auxiliary cutting mechanism 2 also includes an airflow isolation unit 22, which is arranged at the bottom of the oxygenation unit 21, and the airflow isolation unit 22 is used in conjunction with the oxygenation unit 21, and the airflow isolation unit 22 is used to isolate the external airflow in the area with higher oxygen content;

[0050] The airflow isolation unit 22 includes a connecting pipe 2201, one end of which is fixedly connected to the surface of the corrugated hose 2104, and the other end of the connecting pipe 2201 is fixedly connected to a fixed pipe 2203, which is fixedly installed on the bottom of the support plate 2101, and the bottom of the fixed pipe 2203 is fixedly connected to an airflow partition plate 2202. There are four airflow partition plates 2202, which are arranged in a rectangular shape at the bottom of the support plate 2101. By setting the airflow isolation unit 22, the purpose of blocking the fusion of oxygen and external air can be achieved, and excessive fusion between external air and oxygen can be avoided, resulting in a decrease in the oxygen content within the cutting range. It can avoid the fusion between a large amount of air and oxygen, and only a small part will be fused. At the same time, it can avoid the rapid decrease of oxygen content after filtration, further increase the cutting effect, avoid the occurrence of burrs and residues at the cutting position, and further ensure the smoothness of the cutting position.

[0051] A connecting rod 2204 is fixedly installed at the bottom of the airflow dividing plate 2202, an electric telescopic rod 2205 is fixedly installed at one end of the connecting rod 2204, and a guide plate 2206 is fixedly installed at the output end of the electric telescopic rod 2205. By setting the connecting rod 2204 and the electric telescopic rod 2205 for coordinated use, the operator can start the electric telescopic rod 2205 through an external control switch and power supply according to the position of the laser cutting head 14. The start of the electric telescopic rod 2205 drives the guide plate 2206 to move, so that the guide plate 2206 can move to an appropriate position;

[0052] The inner wall of the airflow dividing plate 2202 is fixedly installed with a partition plate 2207. There are several partition plates 2207, and the partition plates 2207 are arranged in a fan shape on the inner wall of the airflow dividing plate 2202. By setting the partition plates 2207, the partition plates 2207 can divert the air entering the interior of the partition plates, so that when the air leaves the partition plates 2207, it can be in a fan-shaped state, thereby ensuring that a wind wall is formed within the cutting range to block the external air and the oxygen within the cutting range.

[0053] The specific implementation of this embodiment is as follows: when increasing the oxygen content during the cutting process of the speaker raw materials, in order to ensure that the outside air does not excessively combine with the air at the cutting site to reduce the oxygen content, when the fan 2102 is started, a portion of the air will enter the inner cavity of the connecting tube 2201, and then enter the inner cavity of the fixed tube 2203 through the connecting tube 2201, and then enter the inner cavity of the air flow dividing plate 2202 through the fixed tube 2203, and then blow the gas out through the air flow dividing plate 2202. The partition plate 2207 inside the air flow dividing plate 2202 can ensure that the air is blown out in a fan-shaped state, so that the front, back, left and right sides of the cutting site form two internal and external barriers. Wind-blocking wall, external air will be blown downward through the external wind-blocking wall and then blown to the outside through the guide plate 2206. The oxygen in the cutting range will be blocked in the cutting range through the internal wind wall and the guide plate 2206, thereby achieving the purpose of blocking the fusion of oxygen and external air. It can avoid excessive fusion between external air and oxygen, resulting in a decrease in the oxygen content in the cutting range. It can avoid the fusion of a large amount of air and oxygen, and only a small part will be fused. At the same time, it can avoid the rapid decrease of oxygen content after filtration, further increasing the cutting effect, avoiding the occurrence of burrs and residues at the cutting position, and further ensuring the smoothness of the cutting position.
