[0002] A large amount of heat is generated during the laser processing. If this heat is not handled in time, it will cause thermal damage to the equipment and materials. Therefore, laser processing equipment is usually equipped with a water cooling device to remove the generated heat in time to maintain the stability of the equipment and materials.

[0003] Before using a laser processor to mark and drill holes in a dielectric filter, it is necessary to preheat it to prevent it from being damaged by direct high-temperature laser irradiation.

[0004] After the filter is marked and punched, some residues produced by laser sintering will remain on its surface. These residues need to be processed in time to avoid affecting the subsequent use of the filter.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a laser processing device for a dielectric filter.

[0036] In a typical implementation of a laser processing device for a dielectric filter of the present application, Figure 1-15 As shown, a laser processing device for a dielectric filter includes a machine tool 1, a laser processor 2, a feeding device 5 and a spray head 7 arranged in the machine tool 1, and the three are in a connected state in sequence. A material transporting device 3 is also arranged in the machine tool 1, and the working path of the material transporting device 3 covers the working range of the laser processor 2, the feeding device 5 and the spray head 7. The feeding device 5 is in the starting section of the material transporting device 3, the laser processor 2 is in the middle section of the material transporting device 3, and the spray head is in the tail section of the material transporting device 3. The material transporting device 3 is used to carry the dielectric filter that has been transported and preheated by the feeding device 5, and drive the dielectric filter to the bottom of the laser processor 2 and the spray head 7 in sequence.

[0037] A cooling pipe 21 is provided in the laser processor 2, and the feeding device 5 includes a plurality of preheating components 52 and driving components 51 symmetrically arranged on both sides of the preheating components 52. The cooling pipe 21, the preheating components 52 and the spray head 7 are connected in sequence. The cooling pipe 21 is attached to the components in the laser processor 2. Coolant flows in the cooling pipe 21. The coolant flows from the cooling pipe 21 to the preheating components 52 and then is sprayed out from the spray head 7.

[0038] When the device is working, the external coolant flows into the cooling pipe 21. After absorbing the high temperature of the components in the laser processor 2, the heated coolant flows into the preheating component 52 to heat and preheat the dielectric filter carried by the feeding device 5. The preheated dielectric filter is transferred to the material transport device 3, and then the laser processor 2 is used to mark and punch the dielectric filter. In this process, after the heated coolant completes the preheating of the dielectric filter, the coolant temperature decreases, and then flows to the spray head 7. At this time, the dielectric filter that has completed marking is transferred to the working range of the spray head 7 on one side through the drive of the material transport device 3. At this time, the cooled coolant is sprayed out from the spray head 7 to spray the dielectric filter and rinse off the residue on its surface. At this time, the coolant still retains some temperature and is sprayed on the dielectric filter after marking and punching. The material temperature will not be increased due to the previous laser irradiation, and then it will not contact with the flushing liquid (i.e., coolant) with a lower temperature, which will cause the material to alternate between hot and cold too much, resulting in damage to the material structure.

[0039] For further information, see Figure 6-Figure 11As shown, the preheating assembly 52 includes a heat spreader 521 and a cover plate 524 which are rotatably connected. Two connecting rods 522 are respectively provided on both sides of the heat spreader 521 for connecting with the driving assembly 51. A groove 523 is provided on the surface of the heat spreader 521 for accommodating a dielectric filter. The interior of the heat spreader 521 is a hollow structure for circulating a heated coolant to preheat the dielectric filter carried by the heat spreader 521. Two connecting holes 525 are provided in the hollow structure and are respectively located on both sides of the tail of the heat spreader 521. Magnetic sheets which are magnetically connected to the heat spreader 521 are provided on both sides of the cover plate 524.

[0040] The plurality of preheating components 52 provided in the feeding device 5 are all driven by the driving component 51. The single-side driving component 51 is provided with two flywheels 511. A first synchronous belt 512 and a second synchronous belt 513 are connected between the two flywheels 511. The driving component 51 guides the plurality of preheating components 52 to reciprocate along the paths of the first synchronous belt 512 and the second synchronous belt 513. An inner wheel 515 is provided on the inner side of the flywheel 511. The first synchronous belt 512 is driven by the flywheel 511, and the second synchronous belt 513 is driven by the inner wheel 515. A shoulder belt 517 is provided on the inner side of the first synchronous belt 512. A reinforcing rib 516 is provided at the connection between the two. The width of the shoulder belt 517 is the same as that of the second synchronous belt 513, and the edges of the two are in an aligned state. A plurality of corresponding connection nodes 514 are provided on the second synchronous belt 513 and the shoulder belt 517. A circular hole is provided on the connection node 514 for connecting with the connecting rod 522.

[0041] The feeding device 5 also includes two annular belts 53 and two guide pipes 54. The annular belts 53 and the guide pipes 54 are each provided with one on both sides of the preheating assembly 52. ​​The annular belt 53 is made of rubber material and is hollow inside. The two annular belts 53 are respectively connected to the connecting holes 525 on one side of a plurality of heat spreaders 521. The guide pipe 54 is rotatably connected to a plurality of connecting pipes, which are connected to the annular belts 53. The connecting points between the connecting pipes and the annular belts 53 are evenly distributed on the annular belts 53. One of the two guide pipes 54 is connected to the cooling pipe 21, and the other is connected to the spray head 7.

[0042] A stand 4 is installed on the outside of the feeding device 5. The stand 4 is used to fix each flywheel 511. The stand 4 is close to the side of the material transport device 3, and an outlet 41 and an inlet 42 are respectively opened at the upper and lower parts. A motor is also arranged in the stand 4. The motor is connected to the driving component 51 through a belt drive, driving the upper and lower flywheels 511 on one side to rotate synchronously in the same direction. The rotation of the flywheel 511 can drive the first synchronous belt 512 and the second synchronous belt 513 to move in a coordinated manner, so as to stably drive the preheating component 52 to move along the path of the first synchronous belt 512 in a predetermined posture. During the movement, when the unloaded preheating component 52 moves to the inlet 42, a storage device 8 for feeding material therein is arranged in the machine tool 1, and the sheet-like dielectric filter is pushed into the containing groove 523. When it is pushed to the end, refer to Fig.11 As shown in , the edge of the dielectric filter contacts the edge of the cover plate 524, and the edge of the cover plate 524 is a vertical corner. When the dielectric filter is completely inserted into the receiving groove 523, it is embedded with the vertical corner to press against the cover plate 524 to prevent the cover plate 524 from rotating. At the same time, the magnetic connection part between the cover plate 524 and the heat spreader 521 can be used to clamp the dielectric filter in the receiving groove 523 to prevent the dielectric filter from loosening and falling off during transportation, so as to ensure stable preheating.

[0043] When the driving assembly 51 is in operation and conveying the dielectric filter, the cooling liquid that has completed cooling the components in the laser processor 2 flows into the guide tube 54 on one side, and the heated cooling liquid is evenly conveyed to the ring belt 53 through a plurality of connecting pipes. The connection between the ring belt 53 and the connecting hole 525 can ensure the stable circulation of the cooling liquid, and will not affect the driving of the preheating assemblies 52 by the driving assembly 51. The cooling liquid that flows into the ring belt 53 on one side flows into the hollow structure in each heat spreader 521 through the connecting hole 525. The heated cooling liquid has a great influence on the preheating assemblies 52 clamped by the preheating assemblies 52. The dielectric filter is preheated and heated. During the heating process, the coolant flows continuously, enters from the connection hole 525 on one side of the heat spreader 521, and then flows out from the connection hole 525 on the other side and merges into the annular belt 53 on the other side, and then flows into the shower head 7 from the guide pipe 54 on the other side, so that the coolant with a higher temperature can always flow into 521 and contact the dielectric filter to preheat the dielectric filter to a predetermined temperature. By cooperating with the driving component 51, the preheating of the filter can be completed while the dielectric filter is being transported, so as to improve the working efficiency of the device;

[0044] It should be added that when the device is working and is just turned on, due to the working time factor, the working temperature of the laser processor 2 will not rise quickly to a higher temperature, and the temperature of the initial flowing coolant will not rise quickly to the predetermined preheating temperature, thereby affecting the preheating of the dielectric filter. A relay node can be set in the machine tool 1 and placed between the connecting line between the laser processor 2 and the guide tube 54. The relay node is set as a container with electrically controlled heating. The coolant with a low initial flowing temperature can be heated to a predetermined high temperature at the node and then continue to be transported to the guide tube 54 to ensure that the dielectric filter is heated to the predetermined preheating temperature.

[0045] For further information, see Figure 5 , Figure 6 and Fig.12 As shown, corresponding to the discharge port 41 and the feed port 42, a first pushing device 6 and a second pushing device 9 are provided in the machine tool 1. The first pushing device 6 is provided on the stand 4 in the machine tool 1. A push plate 61 is provided in the first pushing device 6. The two side edges of the push plate 61 are toothed plate structures. The first pushing device 6 is provided with a gear meshing with the toothed plate structure, and a motor driving the gear. Through the operation of the motor, the push plate 61 can be driven to pop out of the first pushing device 6 or be received in the first pushing device 6. The second pushing device 9 has the same structure as the first pushing device 6, and the push plates 61 included therein are all output toward the feeding device 5.

[0046] See also Figure 5 , Fig.13 and Fig.14 As shown, the material storage device 8 for feeding the preheating assembly 52 is located between the material inlet 42 and the second pushing device 9. The material storage device 8 contains a plurality of dielectric filters. The main structure of the material storage device 8 is a material box 81. The plurality of dielectric filters are placed in the material box 81. A limit plate 82 is installed on the front and rear sides of the material box 81.

A pressure spring 85 is installed in the pier 84. A substrate 86 is commonly connected to the plurality of pressure springs 85. The plurality of dielectric filters are placed on the substrate 86.

[0047] The thickness of the push plate 61 and the thickness of the opening 83 are both adapted to the thickness of the dielectric filter, wherein the width of the push plate 61 needs to be smaller than the width of the dielectric filter, and the width of the push plate 61 also needs to be smaller than the width of the notch 526, and the width of the opening 83 needs to be larger than the width of the dielectric filter. When the device is in working state, during the process of the feeding device 5 guiding the dielectric filter, the second pushing device 9 works first, and the push plate 61 at its output end pops out and is inserted into the opening 83, pushing a dielectric filter in the middle out of the opening 83 on the other side, and the push plate 61 at the output end of the second pushing device 9 is completely output, pushing the single dielectric filter from the material box 81 into the containing groove 523, and pressing against the corner part at the edge of the cover plate 524, at this time, the second pushing device 9 completes its work, and the push plate 61 at its output end is recovered and withdrawn from the material box 81, and after withdrawing from it, another dielectric filter is pushed to the opening 83 by the action of the bottom pressure spring 85, so as to facilitate the next work of the second pushing device 9;

[0048] When the second pushing device 9 is working, the first pushing device 6 is also working synchronously. When this work is in progress, the feeding device 5 is suspended. In this state, one of the preheating components 52 is horizontally aligned with the inlet 42 and the opening 83, and there is another preheating component 52 that is also horizontally aligned with the outlet 41 and the transport device 3. The preheating component 52 is on the side close to the outlet 41, and the preheating component 52 is misaligned with the preheating component 52 on the side away from the outlet 41. It is located between the upper and lower preheating components 52 on the other side. The push plate 61 at the output end of the first pushing device 6 can be inserted into the notch 526 at the tail of the preheating component 52 on this side from the gap between the two preheating components 52 on the other side, and the dielectric filter placed in the containing groove 523 to complete the preheating is pushed to the transport device 3, that is, the feeding and preheating processing of the dielectric filter is completed. The description here can be referred to in detail. Figure 6 .

[0049] Furthermore, the main body of the material transport device 3 is a storage table 31, a collecting groove 34 is opened on the top of the collecting groove 34, a processing table 32 is installed on the top of the collecting groove 34, a plurality of gaps 33 are opened between the processing table 32 and the storage table 31, a slider and a nut structure are arranged at the bottom of the storage table 31, a guide rail connected to the slider and a screw connected to the nut structure are arranged in the machine tool 1, and the material transport device 3 is pushed to slide along the guide rail through the cooperation of the screw rod and the nut. The guide rail is arranged along the working path of the laser processor 2 and extends to the working range of the spray head 7.

[0050] The dielectric filter is transported to the processing table 32 by the first pushing device 6, and after preheating, it moves to the processing area of ​​the laser processor 2, and the laser processor 2 can be used to process the dielectric filter. After the processing is completed, the material transport device 3 continues to drive the dielectric filter to move to the working range of the spray head 7. After reaching the area, the spray head 7 sprays the dielectric filter to cool it and rinse it. After the rinsing is completed, the rinsing liquid (i.e., the coolant) is collected in the collecting tank 34 below through the partition 33 and can be recycled.
