Description

Technical Field

[0001] This application relates to the field of laser processing technology, and in particular to a galvanometer laser processing device. Background Technology

[0002] A galvanometer laser processing equipment is a device that uses lasers to process workpieces.

[0003] Existing galvanometer laser processing equipment generally includes a worktable, a galvanometer head, a movable support, and a laser generator. The galvanometer head is mounted above the worktable via the movable support and can move horizontally and vertically with the movable support. The laser generator is located inside the worktable and can emit laser light to the galvanometer head via an optical fiber.

[0004] However, because the laser has a very high temperature, the galvanometer lens will generate a lot of heat when it is working. When the ambient temperature is high, the heat dissipation efficiency of the galvanometer lens will decrease, which will make the galvanometer laser processing equipment unable to work for a long time.

[0005] Therefore, there is a need to provide a galvanometer laser processing device. Utility Model Content

[0006] To address the problem that existing galvanometer laser processing equipment has low heat dissipation efficiency and cannot operate for extended periods in high ambient temperatures, this application provides a galvanometer laser processing device.

[0007] This application provides a galvanometer laser processing device, which adopts the following technical solution: it includes a worktable, a lifting frame, a galvanometer head, a moving assembly, and a cooling assembly. The lifting frame is disposed on the table surface of the worktable, and the galvanometer head is disposed on the lifting frame and can move up and down with the lifting frame.

[0008] The transfer assembly is disposed between the scanning head and the table surface of the worktable, and the transfer assembly is adapted to receive the workpiece to be processed and drive the workpiece to move in the horizontal direction.

[0009] The cooling assembly includes cooling pipes filled with refrigerant, which are connected to the scanning head.

[0010] By adopting the above technical solution, the cooling pipe can use its internal refrigerant to cool the galvanometer head, so that the cooling component can absorb a large amount of heat generated by the galvanometer head during operation, thereby enabling the galvanometer laser processing equipment to work stably for a long time even when the ambient temperature is high.

[0011] Specifically, the cooling assembly also includes a chassis and a liquid storage tank, a circulating pump, and a heat exchange unit disposed within the chassis. The liquid storage tank is adapted to store refrigerant and has an inlet and an outlet on the tank body. The inlet end of the cooling pipe is connected to the outlet, and the outlet end of the cooling pipe is connected to the inlet. The circulating pump is connected to the cooling pipe and can drive the refrigerant to circulate between the liquid storage tank and the cooling pipe. The heat exchange unit is connected to the portion of the cooling pipe located between the inlet and the oscillating head and can cool the refrigerant in the cooling pipe.

[0012] By adopting the above technical solution, the circulating pump can drive the refrigerant in the storage tank to first enter the inlet end of the cooling pipe from the outlet, then flow through the diaphragm head and absorb the heat generated during its operation to raise its temperature, then pass through the heat exchange unit and be cooled down, and finally return to the storage tank from the outlet end of the cooling pipe through the inlet, so as to form a circulating loop in the cooling pipe and achieve efficient heat dissipation of the diaphragm head.

[0013] Furthermore, the cooling assembly also includes a filter device located inside the chassis, and the filter device is connected to a portion of the cooling pipe located between the liquid outlet and the circulating pump, and is capable of filtering the refrigerant in the cooling pipe.

[0014] By adopting the above technical solution, the filtration device can filter the refrigerant in the cooling pipe, so that impurities generated by the refrigerant during use will not damage the circulating pump.

[0015] Furthermore, the heat exchange unit includes a heat exchange plate and a fan. An air inlet is provided on the top of the casing, and the fan is located inside the air inlet. The cooling pipe includes an S-shaped coil section, which is located on the side of the heat exchange plate facing away from the fan. Multiple heat dissipation fins are spaced apart on the side of the heat exchange plate facing the fan.

[0016] By adopting the above technical solution, the high-temperature refrigerant in the cooling pipe will transfer heat to the heat exchange plate and heat dissipation fins when it flows through the coil section, and the fan can blow the outside air of the chassis from the air inlet to the heat dissipation fins and heat exchange plate, thereby realizing heat dissipation of the heat exchange plate and heat dissipation fins.

[0017] Furthermore, the heat exchange unit also includes a dust filter and a protective railing. The dust filter is disposed in the air inlet, and the fan is located between the dust filter and the heat exchange plate.

[0018] The side wall of the chassis has ventilation openings, and the protective railing is located in the ventilation openings.

[0019] By adopting the above technical solutions, the dust filter can block dust from entering the fan from the outside; the protective railing can protect the equipment inside the chassis and prevent it from falling out of the chassis from the ventilation opening.

[0020] Furthermore, the dustproof net includes a first frame plate, a second frame plate, and a locking plate. One side of the first frame plate is hinged to one side of the air inlet, and one side of the second frame plate is hinged to the other side of the air inlet. Both the first frame plate and the second frame plate are provided with dustproof nets inside, and the first frame plate and the second frame plate can be joined together to block the air inlet.

[0021] One end of the locking plate is connected to the frame on the side of the first frame plate facing the air inlet. The other end of the locking plate extends away from the first frame plate and has a fixing screw hole. The second frame plate has a mounting hole and can abut against the locking plate and be screwed to the first frame plate through the mounting hole and the fixing screw hole by bolts.

[0022] By adopting the above technical solution, the first frame plate and the second frame plate can be assembled and connected by bolts passing through the mounting holes and fixing screw holes.

[0023] Furthermore, the mesh plate is made of metal, and the top of the chassis is provided with two electrostatic dust-collecting plates. The first frame plate and the second frame plate each correspond to one electrostatic dust-collecting plate, and each electrostatic dust-collecting plate can remove dust from the corresponding mesh plate.

[0024] By adopting the above technical solution, users can first separate the first frame plate and the second frame plate from each other, and then use an electrostatic dust suction plate to remove the dust from the mesh plates of the first frame plate and the second frame plate.

[0025] Specifically, the moving assembly includes a mounting pneumatic floating platform and a supporting pneumatic floating platform. The mounting pneumatic floating platform is disposed on the table surface of the worktable, and the supporting pneumatic floating platform is disposed on the floating platform surface of the mounting pneumatic floating platform. The floating platform surface of the supporting pneumatic floating platform is adapted to support the workpiece, and the movement direction of the floating platform surface of the supporting pneumatic floating platform is perpendicular to the movement direction of the floating platform surface of the mounting pneumatic floating platform.

[0026] By adopting the above technical solution, the pneumatic floating platform for the support component and the pneumatic floating platform for mounting enable the moving component to drive the workpiece on the pneumatic floating platform for the support component to move arbitrarily in the horizontal direction, so as to facilitate the processing of the workpiece by the diaphragm head.

[0027] In summary, this application has the following beneficial technical effects:

[0028] The system includes a worktable, a lifting frame, a galvanometer head, a transfer assembly, and a cooling assembly. The lifting frame is mounted on the worktable surface, and the galvanometer head is mounted on the lifting frame and can move up and down with the lifting frame. The transfer assembly is located between the galvanometer head and the worktable surface, and is suitable for receiving the workpiece to be processed and driving the workpiece to move horizontally. The cooling assembly includes cooling pipes filled with refrigerant, which are connected to the galvanometer head and can use their internal refrigerant to cool the galvanometer head. This allows the cooling assembly to absorb the large amount of heat generated by the galvanometer head during operation, thereby enabling the galvanometer laser processing equipment to work stably for a long time even in high ambient temperatures.

See also Figure 1 and Figure 2The galvanometer laser processing equipment provided in this application includes: a worktable 1, a lifting frame 2, a galvanometer head 3, a transfer assembly 4, and a cooling assembly 5. The lifting frame 2 is disposed on the table surface of the worktable 1. The lifting frame 2 is prior art and will not be described in detail here. The galvanometer head 3 is disposed on the lifting frame 2 and can move up and down with the lifting frame 2. The transfer assembly 4 includes a mounting pneumatic float 41 and a supporting pneumatic float 42. The mounting pneumatic float 41 is disposed on the table surface of the worktable 1, and the supporting pneumatic float 42 is disposed on the float surface of the mounting pneumatic float 41. The float surface of the supporting pneumatic float 42 is suitable for receiving workpieces, and the movement direction of the float surface of the supporting pneumatic float 42 is perpendicular to the movement direction of the float surface of the mounting pneumatic float 41. This allows the workpiece on the supporting pneumatic float 42 to be moved arbitrarily in the horizontal direction through the cooperation of the mounting pneumatic float 41 and the supporting pneumatic float 42, thereby facilitating the laser processing of the workpiece by the galvanometer head 3.

[0035] See Figure 1 and Figure 2 The cooling assembly 5 includes a cooling pipe 51 filled with refrigerant, a chassis 52, and a liquid storage tank 53, a circulating pump 54, a heat exchange unit 55, and a filter device 56 located within the chassis 52.

The inlet end of the cooling pipe 51 is connected to the outlet 532, and the outlet end of the cooling pipe 51 is connected to the inlet 531. The filter device 56, the circulating pump 54, the vibrating head 3, and the heat exchange unit 55 are sequentially connected to the cooling pipe 51 in the direction of refrigerant flow. Device 56 can be a cooling water filter to filter the refrigerant in the cooling pipe 51, so that impurities generated by the refrigerant during use will not damage the circulating pump 54. The circulating pump 54 can drive the refrigerant in the storage tank 53 to first enter the inlet end of the cooling pipe 51 from the outlet 532, then flow through the oscillating head 3 and absorb the heat generated during its operation to raise its temperature, then pass through the heat exchange unit 55 and be cooled down, and finally return to the storage tank 53 from the outlet end of the cooling pipe 51 through the inlet 531, so as to form a circulating loop in the cooling pipe 51 and achieve efficient heat dissipation of the oscillating head 3.

[0036] Figure 3 yes Figure 2 A schematic enlarged view of area A in the middle, showing the dust filter screen. Figure 4 It is along Figure 2 A schematic cross-sectional view taken along the BB direction. See also Figure 3 and Figure 4The heat exchange unit 55 includes a heat exchange plate 551, a fan 552, a protective railing 554, and a dust filter 553. An air inlet is located on the top of the casing 52, and the fan 552 is housed within the air inlet. The cooling pipe 51 includes an S-shaped coil section 511, which is located on the side of the heat exchange plate 551 facing away from the fan 552. Multiple heat dissipation fins 5511 are spaced apart on the side of the heat exchange plate 551 facing the fan 552, so that the high-temperature refrigerant in the cooling pipe 51 will transfer heat to the heat exchange plate 551 as it flows through the coil section 554. The fan 552 blows outside air from the air inlet onto the heat exchange fins 5511 and heat exchange plate 551, thereby dissipating heat from the heat exchange plate 551 and heat exchange fins 5511. Ventilation openings are provided on the side walls of the chassis 52, and protective railings 554 are installed in the ventilation openings. These protective railings 554 can protect the equipment inside the chassis 52 and prevent it from falling out of the chassis 52 through the ventilation openings. A dust filter 553 is installed in the air inlet and can block dust from entering the fan 552.

[0037] For details, see Figure 3 and Figure 4 In one embodiment, the dust filter 553 includes a first frame plate 5531, a second frame plate 5532, and a locking plate 5533. One side of the first frame plate 5531 is hinged to one side of the air inlet, and one side of the second frame plate 5532 is hinged to the other side of the air inlet. Both the first frame plate 5531 and the second frame plate 5532 have internal metal mesh plates for dust prevention. One end of the locking plate 5533 is connected to the side frame of the first frame plate 5531 facing the air inlet, and the other end of the locking plate 5533 extends away from the first frame plate 5531 and has a fixing screw hole. The second frame plate 5532 has mounting holes so that the first frame plate 5531 and the second frame plate 5532 can be connected together. The second frame plate 5532 can be assembled to seal the air inlet and connected to the first frame plate 5531 and the second frame plate 5532 by bolts passing through the mounting holes and fixing screw holes; the top of the chassis 52 is provided with two electrostatic dust collection plates 6, with the first frame plate 5531 and the second frame plate 5532 corresponding to one electrostatic dust collection plate 6, so that the user can first separate the first frame plate 5531 and the second frame plate 5532 from each other, and then connect opposite electrodes to the electrostatic dust collection plate 6 and the corresponding mesh plate, so that the dust on the mesh plate is charged and attracted to the electrostatic dust collection plate 6, thereby making it easy to remove the dust from the mesh plates of the first frame plate 5531 and the second frame plate 5532 using the electrostatic dust collection plate 6.

[0038] The working principle of the galvanometer laser processing equipment disclosed in this application is as follows:

[0039] The circulating pump 54 drives the refrigerant in the storage tank 53 to first enter the inlet of the cooling pipe 51 from the outlet 532, then flow through the oscillating head 3 and absorb the heat generated during its operation to rise in temperature. It then passes through the heat exchange unit 55 and is cooled down, finally returning to the storage tank 53 from the outlet of the cooling pipe 51 through the inlet 531. This creates a circulating flow loop within the cooling pipe 51, achieving efficient heat dissipation for the oscillating head 3. Meanwhile, the refrigerant in the cooling pipe 51, which has a higher temperature, will... As the air flows through the coil section 511, heat is transferred to the heat exchange plate 551 and the heat dissipation fins 5511. The fan 552 blows the outside air from the air inlet of the casing 52 onto the heat dissipation fins 5511 and the heat exchange plate 551, thereby dissipating heat from the heat exchange plate 551 and the heat dissipation fins 5511. This allows the cooling component 5 to absorb the large amount of heat generated by the galvanometer 3 during operation, thus enabling the galvanometer laser processing equipment to work stably for a long time even when the ambient temperature is high.

[0040] It should be noted that the above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
