Description

Technical Field

[0001] This invention relates to the field of laser galvanometer technology, and more particularly to a galvanometer reflector mounting structure. Background Technology

[0002] The galvanometer optical path adjusts the position of the light spot by deflecting the reflector through the galvanometer motor, and can be used in scenarios such as laser welding, laser marking, laser engraving, and stage lighting control.

[0003] When assembling the galvanometer optical path, it is necessary to determine the standard zero-point position of the moving end of the galvanometer motor. Existing galvanometer optical path assembly methods require connecting a laser device to output red light to indicate the optical path. With the galvanometer motor body not locked, the entire motor is repeatedly rotated. The rotation of the motor drives changes in the angle of the reflector, gradually finding the precise zero-point position of the galvanometer motor until the laser indicator light and the standard optical path coincide visually. This method of determining the galvanometer motor's zero point is cumbersome and time-consuming. Furthermore, the assembly quality of this method depends entirely on the operator's experience, resulting in significant differences in the assembly and debugging results achieved by different operators.

[0004] However, the reflector is a high-frequency loss component that requires regular maintenance and replacement. After each maintenance, the reassembly of the reflector requires repeating the above-mentioned galvanometer optical path assembly method for zeroing, resulting in high after-sales maintenance thresholds, long maintenance cycles, high operation and maintenance costs for equipment configured with galvanometer optical paths, and a serious impact on on-site production progress.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a galvanometer reflector mounting structure to simplify the maintenance of the galvanometer optical path.

[0007] The technical solution of the present invention is as follows: The galvanometer reflector mounting structure includes a motor mounting base. The motor mounting base is detachably connected to a fixed base and fixedly connected to the galvanometer motor. The motor mounting base has a base positioning part, and the fixed base has a base positioning part that forms a positioning fit with the base positioning part. The movable end of the galvanometer motor is fixedly connected to a mirror frame mounting base. The mirror frame mounting base is detachably connected to a mirror mounting base. The mirror mounting base is fixedly connected to the reflector. The mirror mounting base has a first positioning part, and the mirror frame mounting base has a second positioning part that forms a positioning fit with the first positioning part.

[0008] A further technical solution involves mounting a fastener and a mounting plate surrounding the galvanometer motor on the motor mounting base. The fastener applies a clamping force to the mounting plate, which circumferentially clamps the galvanometer motor.

[0009] A further technical solution involves creating mounting holes on the motor mounting base for connecting to the mounting base. Fasteners are then installed at the mounting holes to pass through and connect to the mounting base.

[0010] A further technical solution is that the mounting hole extends along the radial adjustment direction of the motor mounting base.

[0011] A further technical solution involves setting an insulating layer between the galvanometer motor and the motor mounting base.

[0012] A further technical solution includes a positioning step, which is disposed on the galvanometer motor and / or the insulating layer. When the positioning step is disposed on the galvanometer motor, it contacts the motor mounting base. When the positioning step is disposed on the insulating layer, it contacts the insulating layer.

[0013] The further technical solution is that the first positioning part and the second positioning part are any one of the following: positioning column structure, irregular shape limiting structure, limiting step structure, foolproof positioning structure, snap-on positioning structure, elastic tightening structure, interference fit structure, and clamp locking structure.

[0014] A further technical solution involves providing a mounting plane to support the reflector on the mirror mounting base. The angle between the mounting plane and the movable end is equal to the preset angle between the reflector and the movable end.

[0015] The beneficial technical effects of the present invention are as follows: (1) In the galvanometer and reflector mounting structure of this invention, the galvanometer motor is detachably and positionably connected to the fixed base via a motor mounting base, and the reflector is detachably and positionably connected to the fixed base via a split-type mirror frame. After the initial installation of the reflector, when it is necessary to remove the reflector for maintenance or replacement, the operator can directly remove the motor mounting base connected to the fixed base, and then remove the mirror mounting base connected to the mirror frame mounting base to remove the reflector. When reinstalling the reflector, the positioning structure between the mirror frame mounting base and the mirror mounting base, as well as the positioning structure between the fixed base and the motor mounting base, allows for quick positioning of the reflector. The reflector can be blindly installed in the preset position for quick installation, avoiding the need to find the zero point again when resetting the reflector after removal, eliminating the tedious dimming and calibration steps, and improving the maintenance efficiency of the reflector.

[0016] (2) Further, the motor mounting base clamps the galvanometer motor in a ring, fixing the position between the galvanometer motor and the motor mounting base. The motor mounting base clamps the galvanometer motor through surface contact, reducing the stress per unit area of ​​the galvanometer motor, preventing deformation of the galvanometer motor, and improving the installation accuracy of the galvanometer motor.

Figure 3 An exploded structural schematic diagram of a galvanometer reflector mounting structure according to an embodiment of the present disclosure is shown. Figure 4 A partially enlarged view of the galvanometer-reflector mounting structure according to an embodiment of this disclosure is shown at point A. Please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4The galvanometer and reflector mounting structure includes a motor mounting base 4. The motor mounting base 4 is detachably connected to a fixed base 1 and fixedly connected to a galvanometer motor 2. A base positioning part 442 is provided on the motor mounting base 4, and a base positioning part 12 is provided on the fixed base 1 to form a positioning fit with the base positioning part 442. The movable end 21 of the galvanometer motor 2 is fixedly connected to a mirror frame mounting base 51. The mirror frame mounting base 51 is detachably connected to a mirror mounting base 52. In some embodiments, a mirror frame fastener 524 is provided between the mirror frame mounting base 51 and the mirror mounting base 52, connecting the mirror frame mounting base 51 and the mirror mounting base 52. The mirror frame fastener 524 can be a bolt, screw, or pin, or other known connectors in the prior art; this application does not limit this. The mirror mounting base 52 is fixedly connected to a reflector 6. The mirror mounting base 52 and the reflector 6 can be fixedly connected by adhesive bonding or clamping to form an integrated structure; this application does not limit the connection structure between the mirror mounting base 52 and the reflector 6. A first positioning part 521 is provided on the mirror mounting base 52, and a second positioning part 514 is provided on the mirror frame fixing base 51 to form a positioning fit with the first positioning part 521. The motor fixing base 4 and the galvanometer motor 2, as well as the movable end 21 and the mirror frame fixing base 51, are permanently locked after initial installation and calibration and will not be disassembled. The rigid connection between the motor fixing base 4 and the galvanometer motor 2, and the rigid connection between the movable end 21 and the mirror frame fixing base 51, improves the vibration resistance of the galvanometer reflector mounting structure and prevents the mirror frame fixing base 51 from shifting during vibration, impact, or disassembly and maintenance of the reflector 6. The mirror mounting base 52 and the mirror frame fixing base 51 are detachably connected, and the first positioning part 521 is provided on the mirror mounting base 52, while the second positioning part 514, which cooperates with the first positioning part 521, is provided on the mirror frame fixing base 51. The first positioning part 521 cooperates with the second positioning part 514 to achieve a detachable positioning connection between the mirror mounting base 52 and the mirror frame fixing base 51. The motor mounting base 4 and the mounting base 1 are detachably connected. A base positioning part 442 and a base positioning part 12 are provided between the motor mounting base 4 and the mounting base 1 to achieve a detachable positioning connection. The galvanometer motor 2 is detachably positioned and connected to the mounting base 1 via the motor mounting base 4, and the reflector 6 is detachably positioned and connected to the mounting base 1 via a split-type mirror frame. After the initial installation of the reflector 6, when it needs to be removed for maintenance or replacement, the operator can directly remove the motor mounting base 4 connected to the mounting base 1, and then remove the mirror mounting bracket 52 connected to the mirror frame mounting base 51 to remove the reflector 6.Reinstalling the reflector 6 utilizes the positioning structures between the mirror mount 51 and the mirror mounting base 52, as well as between the fixed base 1 and the motor mounting base 4. This allows for quick and easy positioning of the reflector 6, enabling blind installation into the preset position. The optical path remains consistent after multiple disassembly and reassembly cycles, eliminating the need for a second zero-point search during reassembly and simplifying the tedious dimming calibration process, thus improving the maintenance efficiency of the reflector 6. Furthermore, the secondary disassembly and reassembly steps for the reflector 6 are simple, allowing even personnel without professional dimming experience to independently perform the maintenance work.

[0025] Preferably, the frame holder 51 includes a first holder 511 and a second holder 513, which are separately configured. The first holder 511 and the second holder 513 have opposing slots 512. After the first holder 511 and the second holder 513 are joined, the two slots 512 combine to form a hole corresponding to the outer contour of the movable end 21, thus connecting the frame holder 51 and the movable end 21. In other embodiments, the slots 512 may have radial steps (not shown in the figure) to limit the axial position between the frame holder 51 and the movable end 21. The joining of the first holder 511 and the second holder 513 can be achieved using bolts, screws, or pins, or other connectors known in the prior art; this application does not impose any limitations on this. Specifically, the second holder 513 may also have a retaining ring 515 aligned with its own slot 512. The retaining ring 515 is fitted onto the movable end 21, facilitating quick positioning of the second holder 513 and the movable end 21.

[0026] Please refer to Figure 2 , Figure 3 and Figure 4A fixing member and a mounting plate 43 surrounding the galvanometer motor 2 are provided on the motor mounting base 4. The fixing member applies a clamping force to the mounting plate 43, and the mounting plate 43 clamps the galvanometer motor 2 circumferentially. Specifically, the mounting plate 43 is arranged around the galvanometer motor 2, and clamping holes 421 are respectively opened at both ends of the mounting plate 43. The fixing member passes through the clamping holes 421 at both ends of the mounting plate 43, which can increase the curvature of the mounting plate 43 to clamp the galvanometer motor 2. The motor mounting base 4 clamps the galvanometer motor 2 through surface contact, reducing the stress per unit area of ​​the galvanometer motor 2, preventing deformation of the galvanometer motor 2, and improving the installation accuracy of the galvanometer motor 2. The fixing member can be a fastener known in the prior art such as bolts, nuts, pins, or clamps, and this application does not limit it. Taking bolts as an example, the clamping holes 421 correspond to screw holes. In some embodiments, two or more mounting plates 43 can be provided along the axial direction of the galvanometer motor 2. Multiple mounting plates 43 increase the contact area between the motor mounting base 4 and the galvanometer motor 2, allowing the clamping force of the motor mounting base 4 to be distributed more evenly, avoiding stress concentration that could cause deformation of the galvanometer motor 2's cylinder and affect its installation accuracy. In some embodiments, two or more mounting plates 43 can be provided along the radial direction of the galvanometer motor 2. These multiple mounting plates are connected end to end, collectively encircling the galvanometer motor. Through the motor mounting base 4, the galvanometer motor 2 is completely fixed to the mounting base 1, achieving high installation accuracy. Furthermore, the assembled galvanometer motor 2 has no assembly gaps, no play, and no freedom of insertion or removal, resulting in strong connection rigidity. This enhances the vibration resistance of the entire galvanometer optical path, ensuring the galvanometer motor 2 remains stable and does not loosen during operation.

[0027] Preferably, the motor mounting base 4 has a mounting hole 441 for connecting to the mounting base 1. A fastener (not shown in the figure) passes through the mounting hole 441 and connects to the mounting base 1. In some embodiments, the fastener can be a bolt, screw, or pin, or other known fasteners in the prior art, and this application does not limit this. The mounting hole 441 extends along the radial adjustment direction of the galvanometer motor 2, and the mounting hole 441 can extend into an oblong hole, a rectangular hole, or other shapes.

[0028] In some embodiments, along the radial direction of the galvanometer motor 2, the motor mounting base 4 further includes a mounting end face 44, which abuts against the fixing base 1. A mounting hole 441 can be provided on the mounting end face 44, and the mounting end face 44 also facilitates the installation of a positioning structure to cooperate with the fixing base 1. Specifically, a base positioning part 442 can be provided on the mounting end face 44, and a base positioning part 12 is provided on the fixing base 1 to cooperate with the base positioning part 442, defining the relative position of the fixing base 1 and the motor mounting base 4 along the radial direction of the galvanometer motor 2. Preferably, the mounting end face 44 and the galvanometer motor 2 are strictly perpendicular to each other to ensure the perpendicularity between the galvanometer motor 2 and the fixing base 1 after installation.

[0029] Please refer to Figure 2 , Figure 3 and Figure 4 An insulating layer 3 is provided between the galvanometer motor 2 and the motor mounting base 4. The insulating layer 3 fills the gap between the galvanometer motor 2 and the motor mounting base 4 for insulation. The insulating layer 3 can be made of materials known in the prior art, such as insulating paper or insulating rubber. Taking an open bushing made of insulating material as an example, the insulating layer 3 in the form of an open bushing is fitted onto the galvanometer motor 2. Along the axial direction of the galvanometer motor 2, an opening slit 32 is formed on the cylindrical wall of the insulating layer 3, extending from one end face of the insulating layer 3 to the other end face. When installing the galvanometer motor 2, the insulating layer 3 is first fitted onto the galvanometer motor 2 to fill the gap between the galvanometer motor 2 and the motor mounting base 4. When the motor mounting base 4 contracts, the insulating layer 3 is compressed, the opening slit 32 closes, the inner diameter contracts, it hugs the galvanometer motor 2, and isolates the motor mounting base 4 from the galvanometer motor 2. Furthermore, the open clamping structure of the insulation layer 3 and the motor mounting base 4 allows for quick removal of the galvanometer motor 2 simply by disconnecting the connection between the mounting plate 43 and the galvanometer motor 2. No other auxiliary tools are required, making disassembly and assembly quick and simple. Repeated disassembly and assembly will not damage the mating surfaces of the insulation layer 3, the motor mounting base 4, and the galvanometer motor 2, further reducing the maintenance difficulty of the galvanometer optical path.

[0030] Preferably, the system further includes a positioning step 22, which is disposed on the galvanometer motor 2 and / or the insulating layer 3. When the positioning step 22 is disposed on the galvanometer motor 2, it can contact the motor mounting base 4. When the positioning step 22 is disposed on the insulating layer 3, it can contact the insulating layer 3. Taking a radially oriented positioning step 22 as an example, the positioning step 22 can abut against the end of the insulating layer 3, facilitating quick positioning of the approximate positions of the galvanometer motor 2 and the insulating layer 3 during assembly. In this structure, the end of the insulating layer 3 near the positioning step 22 can extend radially with an annular shoulder 31. The shoulder 31 abuts against the positioning step 22, providing insulation between the motor mounting base 4 and the positioning step 22. The positioning step 22 is only used for pre-alignment and coarse positioning of the galvanometer motor 2 in the early stage of assembly, and is not used as the final rigid limiting structure. After the galvanometer motor 2 completes the axial position fine adjustment and locks it, the positioning step 22 and the motor fixing base 4 maintain a gap and do not contact each other, so as to be compatible with the dimensional tolerance of the galvanometer motor 2 and ensure the axial fine adjustment space of the galvanometer motor 2.

[0031] Please refer to Figure 2 , Figure 3 and Figure 4The first positioning part 521 and the second positioning part 514 can be any one of the following: a positioning post structure, an irregularly shaped limiting structure, a limiting step structure, a foolproof positioning structure, a snap-fit ​​structure, an elastic tightening structure, an interference fit structure, or a clamp locking structure. This application does not impose any limitation on these. In some embodiments, the first positioning part 521 can be a positioning groove with its opening facing the frame fixing seat 51, and the second positioning part 514 can be a positioning boss facing the mirror mounting seat 52. The first positioning part 521 is inserted into the second positioning part 514. The relative positions of the frame fixing seat 51 and the mirror mounting seat 52 are determined by the cooperation between the interior of the positioning groove and the surface of the positioning boss.

[0032] Preferably, a mounting plane 53 is provided on the mirror mounting base 52 to support the reflector 6. The angle between the mounting plane 53 and the movable end 21 is equal to the preset angle between the reflector 6 and the movable end 21. Specifically, the mirror mounting base 52 is provided with a mounting plane 53, and the reflector 6 is positioned by adhering to the mounting plane 53 before being glued or clamped to the mirror mounting base 52. According to the preset angle of the reflector 6, the mounting plane 53 can be opened along the preset angle to quickly position the angle between the reflector 6 and the movable end 21.

[0033] More preferably, the galvanometer-reflector mounting structure of this application, with its detachable connection between the fixed base 1 and the motor fixed base 4, the fixed connection between the motor fixed base 4 and the galvanometer motor 2, the fixed connection between the movable end 21 and the mirror frame fixed base 51, and the detachable connection between the mirror frame fixed base 51 and the mirror mounting base 52, compared to the traditional galvanometer-reflector mounting structure that requires a reserved disassembly / adjustment allowance and a movable mechanism, eliminates the need for a reserved disassembly / adjustment allowance in the galvanometer-reflector mounting structure of this application. This allows for the connection of the fixed base 1, the motor fixed base 4, the mirror frame fixed base 51, and the mirror mounting base 52. The rigid connection between the mounting base 52 and the reflector 6 ensures a fully rigid and locked galvanometer-reflector mounting structure, significantly improving its vibration resistance and anti-displacement performance. Compared to traditional galvanometer-reflector mounting structures that require allowances for disassembly and adjustment and incorporate movable mechanisms, the overall rigidity of the galvanometer-reflector mounting structure in this application is greatly enhanced. When subjected to external environmental impacts such as vibration, bumps, minor collisions, or small drops, it will not experience structural displacement, angular shifts, or optical path misalignment. The optical path remains precise and stable, significantly reducing the failure rate and repair costs of the galvanometer-reflector 6. Furthermore, the mounting structure between the fixed base 1, motor mounting base 4, mirror frame mounting base 51, mirror mounting base 52, and reflector 6 relies on purely mechanical rigid locking and precise positioning to achieve all core functions. It eliminates the need for complex electrical adjustment components, making it simple, reliable, and widely adaptable to various galvanometer-based optical paths, thus possessing high industrial value.

[0034] The specific workflow of this embodiment is as follows: The reflector 6 and mirror mounting base 52 are fixed at the factory. During initial installation, the assembler positions the mirror frame fixing base 51 and mirror mounting base 52 relative to each other using the first positioning part 521 and the second positioning part 514, and connects them using the mirror frame fastener 524. Then, the assembler installs the mirror frame fixing base 51 onto the movable end 21. Afterwards, the assembler places the insulating layer 3 onto the galvanometer motor 2, and the motor fixing base 4 onto the insulating layer 3. The assembler positions the motor fixing base 4 and the fixing base 1 relative to each other using the base positioning part 12 and the base positioning part 442, and connects them using fasteners. At this point, the galvanometer motor 2 is not locked, allowing the assembler to calibrate the optical path. After optical path calibration, the assembler connects the mounting plate 43 using fasteners. The increased curvature of the mounting plate 43 clamps the insulating layer 3 and the galvanometer motor 2, completing the installation of the galvanometer motor 2.

[0035] During subsequent maintenance of the reflector 6, the on-site operator can directly remove the motor mounting base 4 from the fixed base 1, and then remove the mirror mounting base 52 from the mirror frame fixed base 51. This allows the entire structure of the reflector 6 and mirror mounting base 52 to be disassembled for maintenance or replacement of the reflector 6. After replacement, the reflector 6 and mirror mounting base 52 are connected to the mirror frame fixed base 51 via the first positioning part 521, the second positioning part 514, and the fixing component. The motor mounting base 4 is connected to the fixed base 1 via the base positioning part 12 and the base positioning part 442, thus completing the installation of the reflector 6. This disassembly and assembly process does not disturb the zero-point reference of the galvanometer motor 2 body and the motor moving end 21. The position of the reset reflector 6 is completely aligned with the original optical path, eliminating the need for manual zero-point searching, fine-tuning of the optical path, and secondary dimming calibration.

[0036] Example 2 Please refer to Figure 1 and Figure 2Based on Embodiment 1, Embodiment 2 discloses a welding torch, including a welding torch housing 7 and the galvanometer reflector mounting structure of Embodiment 1. A motor mounting base 4 is disposed on the welding torch housing 7. Specifically, a mounting base 1 is disposed on the welding torch housing 7, and the motor mounting base 4 is indirectly fixed to the welding torch housing 7. The mounting base 1 and the welding torch housing 7 can be an integral structure, or they can be separate structures connected by welding, bonding, or other methods; this application does not impose any limitations on this. When maintenance or replacement of the welding torch reflector 6 is required, the operator directly removes the motor mounting base 4 from the welding torch housing 7, and then removes the mirror mounting base 52 connecting the mirror frame mounting base 51, thereby removing the reflector 6. The reflector 6 can be reinstalled. The positioning structure between the mirror holder 51 and the mirror mounting base 52, as well as the positioning structure between the fixed base 1 and the motor fixed base 4, can quickly locate the position of the reflector 6. The reflector 6 can be blindly installed into the preset position for quick installation. This avoids the need to find the zero point again when resetting the reflector 6 after it is removed, eliminates the tedious dimming and calibration steps, and improves the maintenance efficiency of the welding torch.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
