Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, specifically to a laser drilling and cutting device for the metal casing of lamps. Background Technology

[0002] Laser cutting equipment uses a high-power-density laser beam to irradiate the material being cut, quickly heating the material to its vaporization temperature and causing it to evaporate and form a hole. As the beam moves across the material, the hole continuously forms a very narrow kerf, completing the cutting of the material and thus achieving the operation of cutting or drilling workpieces.

[0003] During the manufacturing process of lamps, many lamp housings are made of metal. Therefore, when processing the metal housing of lamps, laser cutting equipment is generally used for drilling and cutting operations. When using laser cutting equipment, the laser head nozzle needs to be suspended above the housing, and then processing is carried out by emitting a laser beam. However, during the processing, the high-temperature debris generated by cutting and drilling will splash onto the laser head nozzle, thereby causing wear on the nozzle, causing the nozzle to deform or become thinner. The contact between the high-temperature debris and the laser head nozzle will not only shorten the life of the laser head nozzle, but in the case of severe deformation, it will also cause the laser irradiation to deviate, thus causing errors in cutting and drilling. Summary of the Invention

[0010] Optionally, the mounting plate has an opening at a position away from the conical filter tube, which is slidably and sealingly connected to the heat dissipation copper fin.

[0011] Optionally, a cylinder is fixed to the top of the water tank, the output shaft of the cylinder is slidably and sealed to the water tank, a pressure plate is fixed to the output shaft of the cylinder, the pressure plate is located inside the water tank, and the top of the pressure plate is in contact with the copper rod.

[0012] Optionally, a spiral plate is fixed to the inner wall of the protective cover.

[0013] Optionally, an arc-shaped plate is fixed inside the water tank, and a second heat-conducting rod is fixed on the surface of the arc-shaped plate, the second heat-conducting rod passing through the water tank.

[0014] Optionally, the second heat-conducting rod does not intersect with the movement trajectory of the laser head, and the diameter of the top of the mounting plate is larger than the diameter of the nozzle.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The laser drilling and cutting device for the metal casing of this lamp uses a protective cover and mounting plate to intercept and protect the high-temperature debris below the nozzle. The exhaust fan draws air from the installation chamber, so that the high-temperature debris passing through the light outlet is collected into the space between the conical filter tube and the filter ring. During the exhaust process, the nozzle is cooled, thereby improving the service life of the nozzle and reducing the probability of nozzle deformation.

[0018] 2. The laser drilling and cutting device for the metal casing of this lamp uses a heat sink copper plate to contact the metal casing of the lamp, allowing the heat sink copper plate to dissipate heat from the cutting area of ​​the metal casing. Subsequently, cooling water in the water tank dissipates heat from the copper rod, connecting ring, first heat-conducting rod, and heat sink copper plate. Then, an exhaust fan ventilates the installation room, further dissipating heat from the heat sink copper plate. Thus, through multiple heat dissipation processes, heat is dissipated from the heat sink copper plate and the metal casing of the lamp, thereby improving the processing accuracy of drilling and cutting the metal casing of the lamp.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figure 1-8 A laser drilling and cutting device for the metal casing of a lamp includes a control cabinet 1. A first hydraulic cylinder 12 is fixed to the top of the control cabinet 1. A second hydraulic cylinder 13 is fixed to the output shaft of the first hydraulic cylinder 12. A first connecting piece 2 is fixed to the bottom of the second hydraulic cylinder 13. A laser head 21 is fixed to the bottom of the first connecting piece 2. A nozzle 211 is fixed to the bottom of the laser head 21. An installation chamber 22 is opened inside the first connecting piece 2. An exhaust fan 23 is fixed inside the installation chamber 22.

[0030] The first connector 2 has air inlet chambers 24 on both sides inside, and the mounting chamber 22 has ventilation openings 25 on both sides. The mounting chamber 22 is connected to the air inlet chamber 24 through the ventilation openings 25. The air inlet chamber 24 is slidably connected to the inside of the air inlet chamber 24. The bottom of the second connector 26 is fixed with a protective cover 27. The inside of the protective cover 27 is a guide chamber 271. The bottom of the protective cover 27 is fixed with a mounting plate 28.

[0031] A light outlet 281 is provided at the center of the base plate of the mounting plate 28. A tapered filter tube 282 is fixed on the base plate of the mounting plate 28 near the light outlet 281. A filter ring 283 is fixed on the base plate of the mounting plate 28 away from the light outlet 281. Locking screws 261 are threaded to both sides of the first connector 2. The locking screws 261 abut against the second connector 26. An air port is provided on the surface of the first connector 2.

[0032] A processing table 11 is fixed on one side of the control cabinet 1, a motor 7 is fixed on one side of the processing table 11, a limit frame 71 is fixed on the top of the processing table 11, a lead screw 72 is fixed on the output shaft of the motor 7, the lead screw 72 is rotatably connected to one side of the limit frame 71, a sliding platform 73 is threadedly connected to the surface of the lead screw 72, transmission screws 74 are threadedly connected to both sides of the sliding platform 73, and a clamping plate 75 is rotatably connected to one end of the two transmission screws 74 that are close to each other.

[0033] During operation, the metal housing of the lamp is first placed on the surface of the sliding platform 73. Then, by adjusting the two transmission screws 74, the transmission screws 74 drive the clamping plate 75 to slide on the surface of the sliding platform 73 until the clamping plate 75 clamps the metal housing, thus fixing the metal housing on the surface of the sliding platform 73.

[0034] Then, the second connector 26 is inserted into the air inlet cavity 24, and the second connector 26 is fixed in the designated position in the air inlet cavity 24 by the locking screw 261. This causes the second connector 26 to drive the protective cover 27 to be sleeved on the outside of the laser head 21, thus protecting the nozzle 211. Subsequently, the first cylinder 12 and the second cylinder 13 are started by the control cabinet 1, so that the first cylinder 12 and the second cylinder 13 drive the first connector 2 to adjust, so that the first connector 2 drives the laser head 21, the second connector 26 and the protective cover 27 to move synchronously.

[0035] Once the laser head 21 moves to the designated position, it can be started through the control cabinet 1. The laser head 21 then performs drilling and cutting operations on the metal shell. During the cutting process, the motor 7 is started through the control cabinet 1, which drives the lead screw 72 to drive the sliding platform 73 and the metal shell on top of the sliding platform 73 to adjust the displacement. The lead screw 72, the first hydraulic cylinder 12, and the second hydraulic cylinder 13 form a three-axis slide system to control the cutting position of the laser head 21. This is a laser cutting positioning technology using multi-axis displacement in the prior art, which will not be described in detail in this invention.

[0036] Specifically, during the actual cutting and drilling process and when high-temperature debris is generated, the protective cover 27 is fitted onto the outside of the laser head 21, that is, the nozzle 211 is protected by the protective cover 27, which reduces the probability of high-temperature debris splashing onto the nozzle 211.

[0037] Meanwhile, since the protective cover 27 is fitted onto the outside of the laser head 21, during the installation of the protective cover 27, the height of the second connector 26 and the protective cover 27 can be adjusted in the air inlet cavity 24, so that the protective cover 27 drives the mounting plate 28 and the conical filter tube 282 to be adjusted synchronously, so that the conical filter tube 282 is fitted onto the outside of the nozzle 211. When the laser head 21 is started, the exhaust fan 23 is started through the control cabinet 1, so that the air around the conical filter tube 282 enters the interior of the guide cavity 271 through the conical filter tube 282, so that the air in the guide cavity 271 enters the interior of the air inlet cavity 24 through the second connector 26, and enters the interior of the installation chamber 22 through the vent 25, and then is discharged to the outside through the air vent on the surface of the installation chamber 22.

[0038] This allows the high-temperature air around the nozzle 211 to enter the interior of the guide cavity 271 when the nozzle 211 is working, thereby playing a role in cooling the nozzle 211.

[0039] Furthermore, such as Figure 3As shown, the light outlet 281 is located below the nozzle 211. When the laser head 21 and the nozzle 211 are cutting, some high-temperature debris is intercepted by the mounting plate 28 and the protective cover 27. The high-temperature debris passing through the light outlet 281 is drawn into the interior of the guide cavity 271 by the exhaust fan 23 and intercepted by the filter ring 283. This allows the high-temperature debris to be collected in the space between the conical filter tube 282 and the filter ring 283, thereby further reducing the impact of high-temperature debris on the nozzle 211, increasing the service life of the nozzle 211, reducing the probability of nozzle 211 deformation, and thus improving the cutting and drilling accuracy of the nozzle 211.

[0040] The high-temperature debris collected in the conical filter tube 282 and filter ring 283 is further cooled by the exhaust fan 23, thereby preventing the high-temperature debris in the conical filter tube 282 from raising the temperature around the nozzle 211 and ensuring the working environment temperature of the nozzle 211.

[0041] After cutting and drilling are completed, the mounting plate 28 can be removed from the bottom of the protective cover 27, and then the debris collected in the space between the conical filter tube 282 and the filter ring 283 can be cleaned away.

[0042] It should be noted that all devices of the present invention are controlled by the control cabinet 1. The mounting plate 28 is fixed to the bottom of the protective cover 27 by bolts. The filter holes on the surface of the conical filter tube 282 are only one layer, and the filter holes of the conical filter tube 282 are larger than the filter holes of the filter ring 283. This allows high-temperature debris near the nozzle 211 to quickly enter the interior of the guide cavity 271 and be collected in the space between the conical filter tube 282 and the filter ring 283.

[0043] Example 2: A water tank 3 is fixed inside the protective cover 27. A copper rod 31 is slidably and sealed to the bottom of the water tank 3. A connecting ring 32 is fixed to the bottom of the copper rod 31. A first heat-conducting rod 33 is fixed to the bottom of the connecting ring 32. A heat-dissipating copper fin 34 is fixed to the bottom of the first heat-conducting rod 33. A limiting plate 35 is fixed inside the heat-dissipating copper fin 34. A snap-fit ​​groove 351 is opened on the bottom plate of the mounting plate 28 away from the conical filter tube 282. The snap-fit ​​groove 351 is slidably and sealed to the heat-dissipating copper fin 34. A cylinder 4 is fixed to the top of the water tank 3. The output shaft of the cylinder 4 is slidably and sealed to the water tank 3. A pressure plate 41 is fixed to the output shaft of the cylinder 4. The pressure plate 41 is located inside the water tank 3, and the top of the pressure plate 41 is in contact with the copper rod 31.

[0044] Specifically, based on Embodiment 1, when installing the second connector 26 and the protective cover 27, the distance between the protective cover 27, the conical filter tube 282, and the nozzle 211 can be adjusted by adjusting the snap-fit ​​depth of the second connector 26 in the air inlet cavity 24. At the same time, the water tank 3 is adjusted synchronously by the protective cover 27, which in turn adjusts the copper rod 31 synchronously. The copper rod 31 then adjusts the connecting ring 32, the first heat-conducting rod 33, and the heat dissipation copper fin 34. By calculating the distance between the nozzle 211 and the metal housing of the lamp, the distance between the nozzle 211 and the bottom of the heat dissipation copper fin 34 is adjusted so that the distance between the nozzle 211 and the bottom of the heat dissipation copper fin 34 is equal to the distance between the nozzle 211 and the metal housing of the lamp.

[0045] During the subsequent cutting process, when the nozzle 211 reaches the cutting height, the bottom of the heat sink 34 contacts the metal casing of the lamp. Then, the nozzle 211 begins cutting. During this process, because the heat sink 34 is in contact with the lamp casing, the heat generated on the surface of the lamp casing during cutting can be transferred to the heat sink 34. Figure 3 As shown, the heat sink 34 is located inside the airflow cavity 271. When the exhaust fan 23 is started, the air inside the airflow cavity 271 is drawn into the installation chamber 22. During the air extraction process, the heat on the surface of the heat sink 34 is transferred to the air inside the airflow cavity 271 and is drawn into the installation chamber 22.

[0046] This allows the exhaust fan 23 to not only exhaust and dissipate heat from the nozzle 211 after it is started, but also to exhaust and dissipate heat from the heat dissipation copper fin 34. In turn, the heat dissipation copper fin 34 dissipates heat from the metal shell of the lamp, reducing the probability of thermal deformation or warping of the metal shell of the lamp due to excessive heat in the cutting area during cutting. This improves the stability of the metal shell of the lamp and ensures the accuracy of subsequent cutting.

[0047] Furthermore, some of the heat on the surface of the heat dissipation copper fin 34 is dissipated by the exhaust fan 23, while the remaining heat on its surface is transferred to the first heat-conducting rod 33, then to the connecting ring 32, and subsequently to the copper rod 31. During this layer-by-layer transfer process, the heat gradually decreases. When the remaining heat is transferred to the copper rod 31, since the copper rod 31 is slidably sealed to the water tank 3 and the water tank 3 contains cooling water, the cooling water in the water tank 3 can absorb heat from the copper rod 31. This further enhances the heat dissipation efficiency of the heat dissipation copper fin 34, thereby improving the heat dissipation efficiency of the heat dissipation copper fin 34 around the cut area of ​​the lamp's metal casing.

[0048] Furthermore, when the laser head 21 and nozzle 211 stop cutting, the cylinder 4 can be controlled by the control cabinet 1 to start cyclically at regular intervals. The cylinder 4 drives the pressure plate 41 to move back and forth inside the water tank 3. During the displacement process, the pressure plate 41 plays the role of stirring the cooling water in the water tank 3, so that the heat absorbed by the cooling water around the copper rod 31 can be quickly diffused into the surrounding cooling water, thereby improving the efficiency of the cooling water in dissipating heat from the copper rod 31, and further improving the heat dissipation efficiency of the heat dissipation copper plate 34 on the metal shell of the lamp.

[0049] During the process of cylinder 4 starting and pushing out, pressure plate 41 gradually approaches copper rod 31 until pressure plate 41 contacts copper rod 31 and then strikes copper rod 31, causing copper rod 31 to vibrate. Through the vibration of copper rod 31 in cooling water, the efficiency of stirring and mixing cooling water temperature is further accelerated, thereby improving the heat dissipation efficiency of copper rod 31 and heat dissipation copper fin 34. At the same time, copper rod 31 drives connecting ring 32, first heat conduction rod 33 and heat dissipation copper fin 34 to vibrate.

[0050] In the process of the protective cover 27 and the mounting plate 28 intercepting high-temperature debris in Embodiment 1, some of the high-temperature debris intercepted by the mounting plate 28 will adhere to the surface of the heat sink copper fin 34, thereby affecting the heat dissipation efficiency of the heat sink copper fin 34. Therefore, by vibrating the heat sink copper fin 34, the high-temperature debris adsorbed on the surface of the heat sink copper fin 34 can be shaken off, thereby improving the heat dissipation efficiency of the heat sink copper fin 34.

[0051] It should be noted that the clean water inside the water tank 3 is injected into the water tank 3 through the water inlet 301, and the water inlet 301 can be sealed by a rubber stopper. The heat dissipation copper fin 34 passes through the snap-fit ​​groove 351, the limiting plate 35 is attached to the surface of the mounting plate 28, and the connecting ring 32 is attached to the surface of the horizontal part of the protective cover 27.

[0052] Example 3: A spiral plate 5 is fixed to the inner wall of the protective cover 27, an arc plate 6 is fixed inside the water tank 3, a second heat-conducting rod 61 is fixed to the surface of the arc plate 6, the second heat-conducting rod 61 passes through the water tank 3, the second heat-conducting rod 61 does not intersect with the movement trajectory of the laser head 21, and the diameter of the top of the mounting plate 28 is larger than the diameter of the nozzle 211.

[0053] Based on Embodiment 1 and Embodiment 2, when the exhaust fan 23 is started, the exhaust fan 23 draws the hot air around the conical filter tube 282 and the nozzle 211 into the interior of the installation chamber 22. During the air extraction process, the air around the laser head 21 is quickly replenished to the area around the nozzle 211, thereby causing the air inside the protective cover 27 to flow from the first connector 2 to the nozzle 211. Under the guidance of the spiral plate 5, the speed at which the air inside the protective cover 27 flows from the first connector 2 to the nozzle 211 is further accelerated, causing the room temperature air inside the protective cover 27 to rush towards the nozzle 211 more quickly, thereby further improving the efficiency of the exhaust fan 23 in dissipating heat from the nozzle 211.

[0054] Furthermore, under the guidance of the spiral plate 5, the air inside the protective cover 27 flows from the first connector 2 to the nozzle 211 and is blown toward the second heat-conducting rod 61. This causes the temperature of the cooling water inside the water tank 3 to be transferred to the arc plate 6 and then to the second heat-conducting rod 61. The blowing of the air inside the protective cover 27 also achieves the purpose of cooling the second heat-conducting rod 61, thereby improving the efficiency of cooling the cooling water inside the water tank 3. The cooling efficiency of the cooling water inside the water tank 3 is maintained by the cooling water, which in turn improves the cooling efficiency of the copper rod 31 and the copper heat sink 34, thereby improving the cooling efficiency of the copper heat sink 34 on the metal casing of the lamp.

[0055] It should be noted that when the exhaust fan 23 is started, the hot air around the nozzle 211 is drawn into the interior of the installation chamber 22. Therefore, the room temperature air inside the protective cover 27 can be quickly replenished to the nozzle 211, thereby dissipating heat from the nozzle 211. At the same time, the room temperature air replenished to the nozzle 211 by the protective cover 27 is blown directly onto the second heat-conducting rod 61 during the surging process. Therefore, the second heat-conducting rod 61 can also receive air-cooled heat dissipation from the room temperature air.
