Summary of the Invention

[0005] The purpose of the present invention is to provide an industrial laser facilitating heat dissipation, which is beneficial to better dissipate heat from the laser body.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: An industrial laser facilitating heat dissipation includes a laser body, a base located below the laser body, a front end plate located at one end of the laser body, an output sleeve located on the front end plate, a lens provided at the front end of the output sleeve, and a rear end plate located at the end of the laser body away from the front end plate. A heat dissipation plate is provided on the upper surface of the laser body. A plurality of heat dissipation fins are provided on the upper surface of the heat dissipation plate. Above the laser body, a connecting sleeve with a "冂"-shaped cross-section and wrapping outside the plurality of heat dissipation fins is provided. Above the connecting sleeve, an axial flow fan that is communicated with the inside of the connecting sleeve and used to convey air flow into the heat dissipation fins is provided.

[0007] By adopting the above technical solution, when the laser body is running, the axial flow fan is started at the same time, wherein the heat sink and the heat sink fins can conduct the heat generated in the laser body, and then the axial flow fan can inject the external airflow into the multiple heat sink fins. At this time, the airflow can take away the heat on the heat sink fins after passing through the multiple heat sink fins, and finally achieve better heat dissipation of the laser body.

[0008] The present invention is further configured as follows: a protective plate for sealing the output sleeve is provided at one end of the front end plate of the laser body, swing arms are provided on both sides of the protective plate, a connecting shaft rotatably connected to the side of the laser body is provided at one end of the swing arm away from the protective plate, and a driving component for opening the protective plate when the laser body and the axial flow fan are started is provided on the laser body.

[0009] By adopting the above technical solution, when the laser body is in operation, the driving assembly drives the protection plate to swing upwards through the swing arm, thereby separating the protection plate from the output sleeve and preventing the protection plate from affecting the laser emitted from the lens; and when the laser body is in a non-operating state, the swing arm can drive the protection plate to swing downwards, thereby sealing the protection plate on the output sleeve. At this time, the lens at the front end of the output sleeve can be protected by the protection plate to prevent the lens from being damaged.

[0010] The present invention is further configured as follows: the driving assembly includes a guide cover arranged at one end of the connecting sleeve close to the protective plate and wrapped around the lower side of multiple heat dissipation fins, a guide cover arranged on the side of the guide cover away from the connecting sleeve and extending along the lower side, a lifting sleeve arranged on the lower side of the guide sleeve, multiple exhaust holes opened on the side of the guide sleeve, a connecting rod arranged at one end of the swing arm away from the protective plate, a long hole opened on the connecting rod, and a driving shaft arranged at the end surface of the lifting sleeve and passing through the long hole.

[0011] By adopting the above technical solution, when the laser body and the axial flow fan are started, a part of the airflow after passing through the heat dissipation fins will enter the guide cover. Under the push of the high-speed airflow, the lifting sleeve can move downward on the guide sleeve until the lifting sleeve moves down to the position below the exhaust hole and the exhaust hole is exposed, so that the airflow in the guide sleeve can be discharged through the exhaust hole; at this time, the lifting sleeve that moves downward can push the connecting rod to swing downward through the cooperation of the driving shaft and the long strip hole, and the connecting rod can drive the swing arm and the protective plate to swing upward, and finally the protective plate can be opened, so that the protective plate is separated from the output sleeve;

[0012] When the laser body and the axial flow fan stop, the high-speed airflow is lost in the air guide cover. At this time, the protection plate and the swing arm can swing downward under the action of their own gravity, and finally the protection plate can be sealed on the output sleeve, and the lens at the front end of the output sleeve is protected by the protection plate; at the same time, the downward swing of the swing arm can drive the connecting rod to swing upward, and the connecting rod can drive the lifting sleeve to move upward on the air guide sleeve through the driving shaft, so that the exhaust hole can be closed again by the lifting sleeve, which is convenient for driving the lifting sleeve to move downward after the axial flow fan is turned on next time.

[0013] The present invention is further configured as follows: the opening size of the air guide cover facing the plurality of heat dissipation fins is larger than the opening size facing the air guide sleeve.

[0014] By adopting the above technical solution, the opening size of the air guide cover facing the multiple heat dissipation fins is larger than the opening size facing the air guide sleeve. At this time, more airflow can be introduced into the air guide cover, which is conducive to pushing the lifting sleeve downward.

[0015] The present invention is further configured as follows: the plurality of exhaust holes are located on a side of the guide sleeve close to the protective plate, and when the swing arm drives the protective plate to swing upward to an extreme position, the protective plate is in a downwardly tilted state and faces the plurality of exhaust holes.

[0016] By adopting the above technical solution, multiple exhaust holes are located on the side of the guide sleeve close to the protective plate, wherein when the swing arm drives the protective plate to swing upward to the extreme position, the protective plate is in a downward tilted state and is directly opposite to the multiple exhaust holes, so that the high-speed airflow discharged from the exhaust holes can be sprayed onto the tilted protective plate, and the tilted protective plate can guide the high-speed airflow. Under the guiding effect of the protective plate, the high-speed airflow can flow obliquely downward and then be sprayed at a position near the lens. At this time, the dust and other debris particles near the lens can be blown away by the high-speed airflow, so as to prevent the dust and other debris particles from affecting the laser emitted from the lens, which can ultimately help to ensure the high-precision characteristics of the laser.

[0017] The present invention is further configured as follows: downwardly inclined guide plates are provided on the inner walls on both sides of the protection plate.

[0018] By adopting the above technical solution, the guide plates on the inner walls on both sides of the protective plate can be used to guide the high-speed airflow passing through the protective plate, so that the high-speed airflow can be concentrated and sprayed near the lens, which is conducive to efficiently cleaning dust and other debris particles near the lens.

[0019] The present invention is further configured as follows: a protective airbag ring is provided on the inner wall of the protective plate corresponding to the end face position of the output sleeve; when the protective plate is sealed on the output sleeve, the protective airbag ring is pressed against the end face of the output sleeve on the peripheral side of the lens.

[0020] By adopting the above technical solution, a protective airbag ring is arranged on the inner wall of the protection plate corresponding to the end face of the output sleeve. When the protection plate is sealed on the output sleeve, the protective airbag ring can be pressed against the end face of the output sleeve on the peripheral side of the lens. The lens can be protected by the elastic characteristics of the protective airbag ring itself. When the protection plate is subjected to external pressure, the protective airbag ring can buffer the pressure, thereby ultimately avoiding the situation where the lens is damaged after the protection plate is pressed.

[0021] The present invention is further configured as follows: a groove for the protection airbag ring to fit into is provided on the inner wall of the protection plate, and an inflation and deflation component for inflating and deflation of the protection airbag ring is provided on the laser body.

[0022] By adopting the above technical solution, since there is a protective airbag ring on the inner wall of the protection plate, the high-speed airflow passing through the inner wall of the protection plate may be disturbed by the protective airbag ring protruding from the inner wall of the protection plate;

[0023] At this time, the inflation and deflation assembly provided on the laser body is used to inflate and deflate the protective airbag ring. When the protection plate swings upward and separates from the lens, the inflation and deflation assembly can deflate the protective airbag ring, so that the protective airbag ring shrinks and fits in the groove, thereby reducing the possibility that the protective airbag ring has a significant impact on the high-speed airflow passing through the inner wall of the protection plate; and when the protection plate swings downward and needs to be sealed on the lens, the inflation and deflation assembly can inflate the protective airbag ring, so that the protective airbag ring is inflated and pressed against the end face of the output sleeve on the side of the lens, which is ultimately beneficial to protecting the lens through the protective airbag ring.

[0024] The present invention is further configured as follows: the inflation and deflation assembly includes a piston cylinder arranged on a swing arm, an air pipe connected to the end of the piston cylinder at one end and connected to a protective airbag ring at the other end, a piston rod embedded in an end of the piston cylinder away from the air pipe, a return spring arranged in the piston cylinder and with its end pressed against an end surface of the piston rod, an open groove provided at the end of the piston rod away from the piston cylinder, a roller rotatably connected to the open groove, a guide plate provided at a side of the laser body, a guide arc surface provided on the guide plate and for the roller to abut, and a connecting column provided on the lower side of the guide plate and connected to the side of the laser body.

[0025] By adopting the above technical solution, when the protection plate and the swing arm swing downward, the roller at the end of the piston rod can roll downward along the guide arc on the guide plate, so that the roller can be compressed, and then the piston rod can move toward the inside of the piston cylinder, and the return spring is compressed. At this time, the air in the piston cylinder can be injected into the protection airbag ring through the air pipe, so that the protection airbag ring is inflated;

[0026] When the protection plate and the swing arm swing upward, the roller at the end of the piston rod can roll upward along the guide arc on the guide plate, and then the reset spring can elastically recover, and the reset spring can push the piston rod to move out of the piston cylinder. At this time, the piston cylinder can draw out the air in the protection airbag ring through the air pipe, so that the protection airbag ring can shrink and fit on the inner wall of the groove.

[0027] The beneficial effect of the present invention is that when the laser body is running, the axial flow fan is started at the same time, wherein the heat dissipation plate and the heat dissipation fins can conduct the heat generated in the laser body, and then the axial flow fan can inject the external airflow into the multiple heat dissipation fins, and at this time, the airflow can take away the heat on the heat dissipation fins after passing through the multiple heat dissipation fins, and finally the laser body can be better cooled;

[0028] When the laser body and the axial flow fan are started, a part of the airflow after passing through the heat dissipation fins will enter the guide cover. Under the push of the high-speed airflow, the lifting sleeve can move downward on the guide cover until the lifting sleeve moves down to the position below the exhaust hole to expose the exhaust hole, so that the airflow in the guide cover can be discharged through the exhaust hole; at this time, the lifting sleeve that moves downward can push the connecting rod to swing downward through the cooperation of the driving shaft and the long hole, and the connecting rod can drive the swing arm and the protective plate to swing upward, and finally the protective plate can be opened, so that the protective plate is separated from the output sleeve. When the laser body and the axial flow fan stop, the high-speed airflow is lost in the air guide cover. At this time, the protection plate and the swing arm can swing downward under the action of their own gravity, and finally the protection plate can be sealed on the output sleeve, and the lens at the front end of the output sleeve is protected by the protection plate; at the same time, the swing arm swings downward to drive the connecting rod to swing upward, and the connecting rod can drive the lifting sleeve to move upward on the air guide sleeve through the driving shaft, so that the exhaust hole is closed again by the lifting sleeve, which is convenient for driving the lifting sleeve to move downward after the axial flow fan is turned on next time;

[0029] Multiple exhaust holes are located on one side of the guide sleeve close to the protective plate. When the swing arm drives the protective plate to swing upward to the extreme position, the protective plate is in a downward tilted state and faces the multiple exhaust holes. Therefore, the high-speed airflow discharged from the exhaust holes can be sprayed on the tilted protective plate, and the tilted protective plate can guide the high-speed airflow. Under the guidance of the protective plate, the high-speed airflow can flow downward and spray near the lens. At this time, the dust and other debris particles near the lens can be blown away by the high-speed airflow to prevent the dust and other debris particles from affecting the laser emitted from the lens, which is ultimately conducive to ensuring the high-precision characteristics of the laser.

[0030] At the same time, when the protection plate and the swing arm swing downward, the roller at the end of the piston rod can roll downward along the guide arc surface on the guide plate, so that the roller can be compressed, and then the piston rod can move toward the inside of the piston cylinder, and the return spring is compressed. At this time, the air in the piston cylinder can be injected into the protection airbag ring through the air pipe, so that the protection airbag ring can swell, and the swollen protection airbag ring can be pressed against the end face of the output sleeve on the side of the lens. The lens can be protected by the elastic characteristics of the protection airbag ring itself. When the protection plate is subjected to external pressure, the protection airbag ring can press The force acts as a buffer, and finally the situation that the lens is damaged after the protection plate is compressed can be avoided; and when the protection plate and the swing arm swing upward, the roller at the end of the piston rod can roll upward along the guide arc surface on the guide plate, and then the reset spring can elastically recover, and the reset spring can push the piston rod to move toward the outside of the piston cylinder. At this time, the piston cylinder can draw away the air in the protection airbag ring through the air pipe, so that the protection airbag ring can be deflated and fit to the inner wall of the groove, and finally the possibility of the protection airbag ring having a greater impact on the high-speed airflow passing through the inner wall of the protection plate can be reduced.

At the same time, the plurality of exhaust holes 54 are located on the side of the guide sleeve 52 close to the protection plate 4. When the swing arm 41 drives the protection plate 4 to swing upward to the limit position, the protection plate 4 is in a downward inclined state and is directly opposite to the position of the plurality of exhaust holes 54. On the inner walls of both sides of the protection plate 4, downward inclined guide plates 42 are welded.

At the same time, the driving shaft 57 is welded to the end face of the lifting sleeve 53 and passes through the long strip hole 56.

[0044] Refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 , a protective airbag ring 43 corresponding to the end face position of the output sleeve 121 is also provided on the inner wall of the protective plate 4, wherein a groove 44 for bonding and fitting the protective airbag ring 43 is opened on the inner wall of the protective plate 4. At this time, when the protective plate 4 is sealed on the output sleeve 121, the protective airbag ring 43 can be tightly pressed against the end face of the output sleeve 121 on the peripheral side of the lens 122; at the same time, an air charging and discharging component 6 for inflating and discharging the protective airbag ring 43 is also provided on the laser body 1, and the air charging and discharging component 6 includes a piston cylinder 61, an air pipe 62, a piston rod 63, a reset spring 64, an opening groove 65, a roller 66, a guide plate 67, a guide arc surface 68, and a connecting column 69, wherein the piston cylinder 61 is bonded to the side wall of the swing arm 41, and the air pipe 62 is connected to the end of the piston cylinder 61 at one end and the other end The end is connected to the protective airbag ring 43, and the air pipe 62 is bonded to the inner wall of the protective plate 4; at the same time, one end of the piston rod 63 is embedded in the end of the piston cylinder 61 away from the air pipe 62, and the return spring 64 is arranged in the piston cylinder 61, wherein one end of the return spring 64 is tightly against the end face of the piston rod 63 and the other end is tightly against the bottom wall of the piston cylinder 61, and the opening groove 65 is opened at the end of the piston rod 63 away from the piston cylinder 61, and the roller 66 is rotatably connected in the opening groove 65 through the shaft and the bearing, wherein the guide plate 67 is located at the side of the laser body 1, and the guide arc surface 68 is opened on the guide plate 67 and is abutted by the roller 66, and at the same time, one end of the connecting column 69 is welded to the lower side of the guide plate 67 and the other end is welded to the side of the laser body 1.

[0045] Principle: When the laser body 1 is running, the axial flow fan 31 is started at the same time, wherein the heat sink 2 and the heat sink fins 21 can conduct the heat generated in the laser body 1, and then the axial flow fan 31 can inject the external airflow into the multiple heat sink fins 21. At this time, the airflow can take away the heat on the heat sink fins 21 after passing through the multiple heat sink fins 21, and finally achieve better heat dissipation of the laser body 1;

[0046] When the laser body 1 and the axial flow fan 31 are started, a part of the airflow after passing through the heat dissipation fins 21 will enter the air guide cover 51. Under the push of the high-speed airflow, the lifting sleeve 53 can move downward on the air guide sleeve 52 until the lifting sleeve 53 moves down to the position below the exhaust hole 54, and then the exhaust hole 54 can be exposed, so that the airflow in the air guide sleeve 52 can be discharged through the exhaust hole 54; at this time, the lifting sleeve 53 that moves downward can push the connecting rod 55 to swing downward through the cooperation of the driving shaft 57 and the long hole 56, and the connecting rod 55 can drive the swing arm 41 and the protective plate 4 to swing upward, and finally the protective plate 4 can be opened, so that the protective plate 4 is separated from the output sleeve 121; When the laser body 1 and the axial flow fan 31 stop, the high-speed airflow is lost in the air guide cover 51. At this time, under the action of the self-weight of the swing arm 41 and the protection plate 4, the protection plate 4 and the swing arm 41 can swing downward, and finally the protection plate 4 can cover the output sleeve 121, and the lens 122 at the front end of the output sleeve 121 can be protected by the protection plate 4; at the same time, the swing arm 41 swings downward to drive the connecting rod 55 to swing upward, and the connecting rod 55 can drive the lifting sleeve 53 to move upward on the air guide sleeve 52 through the driving shaft 57, so that the exhaust hole 54 is closed again by the lifting sleeve 53, which is convenient for driving the lifting sleeve 53 to move downward after the axial flow fan 31 is turned on next time;

[0047] A plurality of exhaust holes 54 are located on one side of the guide sleeve 52 close to the protective plate 4. When the swing arm 41 drives the protective plate 4 to swing upward to the extreme position, the protective plate 4 is in a downward tilted state and directly faces the plurality of exhaust holes 54. Therefore, the high-speed airflow discharged from the exhaust holes 54 can be sprayed on the tilted protective plate 4, and the tilted protective plate 4 can guide the high-speed airflow. Under the guidance of the protective plate 4, the high-speed airflow can flow tilted downward and then sprayed at a position near the lens 122. At this time, the dust and other debris particles near the lens 122 can be blown away by the high-speed airflow to prevent the dust and other debris particles from affecting the laser emitted from the lens 122, which can ultimately help ensure the high-precision characteristics of the laser.

[0048] At the same time, when the protection plate 4 and the swing arm 41 swing downward, the roller 66 at the end of the piston rod 63 can roll downward along the guide arc surface 68 on the guide plate 67, so that the roller 66 can be compressed, and then the piston rod 63 can move toward the piston cylinder 61, and the return spring 64 is compressed. At this time, the air in the piston cylinder 61 can be injected into the protection airbag ring 43 through the air pipe 62, so that the protection airbag ring 43 is inflated, and the inflated protection airbag ring 43 can be pressed against the end face of the output sleeve 121 on the side of the lens 122. The lens 122 can be protected by the elastic characteristics of the protection airbag ring 43 itself. When the protection plate 4 is subjected to external pressure, the protection airbag ring 43 is It can buffer the pressure and ultimately avoid the situation where the lens 122 is damaged after the protection plate 4 is compressed; and when the protection plate 4 and the swing arm 41 swing upward, the roller 66 at the end of the piston rod 63 can roll upward along the guide arc surface 68 on the guide plate 67, and then the reset spring 64 can elastically recover, and the reset spring 64 can push the piston rod 63 to move toward the outside of the piston cylinder 61. At this time, the piston cylinder 61 can extract the air in the protection airbag ring 43 through the air pipe 62, so that the protection airbag ring 43 is deflated and fits on the inner wall of the groove 44, and ultimately can reduce the possibility of the protection airbag ring 43 having a significant impact on the high-speed airflow passing through the inner wall of the protection plate 4.
