[0051] In related technologies, the mounting base for a laser galvanometer module includes a clamping arm that holds the galvanometer firmly onto the mounting base. The end of the clamping arm is locked to the mounting base with screws. However, after the clamping arm is locked to the mounting base with screws, not only will the position of the clamping arm shift, causing the galvanometer to shift, but also, when the galvanometer is reciprocating, it is impossible to achieve a stable and reliable fixation for the galvanometer.

[0052] To address the aforementioned technical problems, this disclosure provides a laser galvanometer module. The laser galvanometer module includes a mounting base, a galvanometer assembly, and a locking assembly. The mounting base has a mounting hole, and a portion of the galvanometer assembly passes through the mounting hole. The locking assembly includes a clamping member and a locking member, both of which are fitted between the wall of the mounting hole and the galvanometer assembly. At least a portion of the clamping member is located between the locking member and the galvanometer assembly, thereby facilitating the deformation of the clamping member and its encirclement of the galvanometer assembly by the locking member pressing against the clamping member.

[0053] Furthermore, by setting a threaded connection between the locking element and the mounting hole wall, on the one hand, it facilitates the installation and disassembly of the locking element, thereby facilitating the fixing and disassembly of the galvanometer assembly. On the other hand, it ensures the smoothness and reliability of the locking element's rotation and compression of the clamping element, thus guaranteeing the reliability of the clamping element's deformation and gripping of the galvanometer assembly. This not only helps to ensure that the position of the galvanometer assembly does not shift after being gripped, but also facilitates stable and reliable fixing of the galvanometer assembly during its reciprocating rotation.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0056] Reference Figures 1 to 9 As shown in the figure, this disclosure provides a laser galvanometer module. Applications of this laser galvanometer module include, but are not limited to, cameras, laser printers, laser cutters, optical modulators, laser modeling, laser marking, laser drilling, and laser welding.

[0057] The laser galvanometer module of this disclosure includes a mounting base 100, a galvanometer assembly 300, and a locking assembly 200. The mounting base 100 has a mounting hole 110, and a portion of the galvanometer assembly 300 passes through the mounting hole 110. Exemplarily, the galvanometer assembly 300 includes a drive motor 320 and a galvanometer 310. The galvanometer 310 is disposed at the output end of the drive motor 320, allowing the drive motor 320 to drive the galvanometer 310 to rotate. The drive motor 320 may include a motor body 321 and a connecting arm 322. The connecting arm 322 is connected to the end of the motor body 321 near the output end, and the galvanometer 310 is connected to the end of the connecting arm 322 away from the motor body 321. This disclosure uses the example of the connecting arm 322 of the galvanometer assembly 300 passing through the mounting hole 110 for illustration. It is understood that other parts of the galvanometer assembly 300 can also pass through the mounting hole 110, as long as the installation requirements of the galvanometer 310 and the requirements of this disclosure are met.

[0058] The locking assembly 200 includes a clamping member 220 and a locking member 210. Both the clamping member 220 and the locking member 210 can be sleeved between the wall of the mounting hole 110 and the connecting arm 322 of the galvanometer assembly 300, with at least a portion of the clamping member 220 located between the locking member 210 and the connecting arm 322 of the galvanometer assembly 300. The locking member 210 is threadedly connected to the wall of the mounting hole 110, allowing the locking member 210 to move along the axial direction of the mounting hole 110 towards the clamping member 220 and compress the clamping member 220. It should be noted that the direction in which the locking member 210 moves along the axial direction of the mounting hole 110 towards the clamping member 220 is the locking direction between the locking member 210 and the mounting hole 110. When the locking member 210 is locked to the mounting hole 110, the clamping member 220 deforms and grips the connecting arm 322 of the galvanometer assembly 300.

[0059] When it is necessary to remove the galvanometer assembly 300, simply rotate the locking member 210 to move it away from the clamping member 220 along the axial direction of the mounting hole 110. This causes the clamping member 220 to loosen the connecting arm 322 of the galvanometer assembly 300, allowing the galvanometer assembly 300 to be removed. The locking member 200 can circumferentially clamp the connecting arm 322 of the galvanometer assembly 300, thus ensuring that the position of the galvanometer assembly 300 will not shift after being clamped. Moreover, the clamping effect is better, providing stable and reliable fixation of the galvanometer assembly 300 when the galvanometer 310 reciprocates during operation.

[0060] In one possible implementation, the locking assembly 200 may further include a clamping sleeve 230, which is sleeved between the clamping member 220 and the galvanometer assembly 300, so that the clamping member 220 can clamp the connecting arm 322 of the galvanometer assembly 300 by squeezing the clamping sleeve 230. For example, the material of the clamping sleeve 230 may include, but is not limited to, rubber. The clamping sleeve 230 serves two purposes: firstly, it provides anti-slip properties, thereby ensuring the reliability of the locking assembly 200's clamping of the connecting arm 322 of the galvanometer assembly 300; secondly, it reduces localized compression of the connecting arm 322 of the galvanometer assembly 300 by the clamping member 220, resulting in a more uniform distribution of the clamping force applied by the clamping member 220 to the connecting arm 322 of the galvanometer assembly 300, and a better clamping effect on the galvanometer assembly 300.

[0061] In one possible implementation, the inner peripheral wall of the locking member 210 includes a guide surface 211. The first end of the clamping member 220 near the locking member 210 abuts against the guide surface 211. The guide surface 211 is used to move the first end of the clamping member 220 along the guide surface 211 during the locking process of the locking member 210 and the mounting hole 110, so that the first end of the clamping member 220 contracts radially and clamps the connecting arm 322 of the galvanometer assembly 300. In some examples, the guide surface 211 may surround the inner peripheral wall of the locking member 210 to form an inclined surface like the side of a frustum. From the direction from the clamping member 220 to the locking member 210, the inclined surface gradually slopes towards the connecting arm 322 of the galvanometer assembly 300. In other examples, the guide surface 211 may surround the inner peripheral wall of the locking member 210, and the guide surface 211 may be an arc surface that gradually narrows in diameter from the clamping member 220 toward the locking member 210. The guide surface 211 can better guide the clamping member 220 to deform radially and hold the connecting arm 322 of the galvanometer assembly 300, thereby ensuring the stability and reliability of the locking member 210 in holding the galvanometer assembly 300.

[0062] In one possible implementation, the first end of the clamping member 220 has a chamfer or rounded corner on one edge near the guide surface 211. This ensures that the first end of the clamping member 220 can slide smoothly along the guide surface 211 and deform radially to hold the connecting arm 322 of the galvanometer assembly 300.

[0063] In one possible implementation, the clamping member 220 includes an abutment portion 221 and a gripper portion 222 fixedly connected to each other. The gripper portion 222 includes a plurality of sub-grippers 2221, which are spaced apart circumferentially along the clamping member 220. The gripper portion 222 is the first end of the clamping member 220. For example, the plurality of sub-grippers 2221 can be arranged at equal intervals circumferentially along the clamping member 220 to ensure that the clamping force of the clamping member 220 on the galvanometer assembly 300 can be evenly distributed circumferentially along the connecting arm 322 of the galvanometer assembly 300.

[0064] In one possible implementation, multiple sub-clamps 2221 extend in the direction from the abutment portion 221 to the clamping portion 222, and the ends of the multiple sub-clamps 2221 away from the abutment portion 221 are inclined clockwise or counterclockwise relative to the ends of the multiple sub-clamps 2221 near the abutment portion 221. This allows the multiple sub-clamps 2221 to smoothly tilt clockwise or counterclockwise and retract radially along the clamping member 220 when the locking member 210 presses against the first end of the clamping member 220, so as to smoothly grip the connecting arm 322 of the galvanometer assembly 300, ensuring that the clamping force applied by the multiple sub-clamps 2221 to the connecting arm 322 of the galvanometer assembly 300 is evenly distributed. This further avoids mutual pushing and interference caused by inconsistent tilting directions of the sub-clamps 2221, resulting in uneven distribution of clamping force.

[0065] In one possible implementation, the ends of the multiple sub-clamps 2221 that are away from the abutment portion 221 are tilted toward the galvanometer assembly 300 relative to the ends of the multiple sub-clamps 2221 that are near the abutment portion 221. This allows the ends of the multiple sub-clamps 2221 that are away from the abutment portion 221 to smoothly retract radially along the clamping member 220 and grip the connecting arm 322 of the galvanometer assembly 300 when the locking member 210 presses against the first end (clamp portion 222) of the clamping member 220, preventing the sub-clamps 2221 from jamming and affecting the locking process and locking effect of the locking assembly 200.

[0066] In one possible implementation, an extension 223 is provided on the inner peripheral wall of the end of the abutment portion 221 away from the gripper portion 222, and the extension 223 extends toward the direction close to the galvanometer assembly 300. For example, the extension 223 may surround the inner peripheral wall of the end of the abutment portion 221 away from the gripper portion 222, or the extension 223 may include multiple extension segments that are circumferentially spaced along the inner peripheral wall of the end of the abutment portion 221 away from the gripper portion 222.

[0067] The side of the extension 223 facing away from the gripper 222 abuts against the mounting base 100. This allows the mounting base 100 to push against the end of the clamping member 220 away from the locking member 210 when the locking member 210 presses against the clamping member 220, preventing the locking member 210 from sliding axially along the connecting arm 322 of the galvanometer assembly 300. This ensures the locking effect and reliability of the locking assembly 200. The side of the extension 223 facing the gripper 222 abuts against the end of the clamping sleeve 230 away from the locking member 210, preventing the clamping sleeve 230 from sliding axially along the connecting arm 322 of the galvanometer assembly 300. This also ensures the locking effect and reliability of the locking assembly 200. Furthermore, the presence of the extension 223 increases the structural strength of the clamping member 220 and reduces the probability of breakage during deformation.

[0068] In one possible implementation, the inner peripheral wall of the clamping sleeve 230 is provided with a protrusion 231, which abuts against the galvanometer assembly 300, thereby further improving the anti-slip effect of the clamping sleeve 230 and further ensuring the reliability of the locking assembly 200 clamping the connecting arm 322 of the galvanometer assembly 300. In some examples, the protrusion 231 can extend circumferentially along the clamping sleeve 230. For example, the protrusion 231 can extend along the inner peripheral wall of the clamping sleeve 230 and circle it once, twice, or more times. The two or more protrusions 231 can be spaced apart axially along the clamping sleeve 230. In other examples, the protrusion 231 can include multiple protrusion segments 231, which can be spaced apart circumferentially on the inner peripheral wall of the clamping sleeve 230.

[0069] In one possible implementation, the locking member 210 includes a threaded connection portion 212 and a rotation control portion 213. The threaded connection portion 212 is threadedly connected to the wall of the mounting hole 110. For example, the outer peripheral wall of the threaded connection portion 212 is provided with external threads, and the wall of the mounting hole 110 is provided with internal threads, with the external threads and internal threads matching each other. The rotation control portion 213 is connected to the end of the threaded connection portion 212 facing the clamping member 220. The outer peripheral surface of the rotation control portion 213 is used to cooperate with the tool 600 for rotating the locking member 210. For example, the rotation control portion 213 can be hexagonal in shape, and the tool 600 for rotating the locking member 210 can be a wrench. The wrench can clamp the hexagonal rotation control portion 213 and rotate it to lock the locking member 210 to the mounting hole 110.

[0070] In one possible implementation, the mounting base 100 is further provided with a clearance notch 120, which is located at the axial center of the mounting hole 110. The rotation control part 213 extends into the clearance notch 120. The clearance notch 120 is used to avoid the tool 600 of the rotating locking member 210, thereby facilitating the installation of the locking member 210 and ensuring the efficiency of the locking assembly 200 in locking the galvanometer assembly 300.

[0071] In one possible implementation, the mounting base 100 is further provided with a stop portion 130, which is located at the end of the mounting hole 110 away from the locking member 210. The end of the clamping member 220 away from the locking member 210 abuts against the stop portion 130. Thus, when the locking member 210 squeezes the clamping member 220, the stop portion 130 can better push the end of the clamping member 220 away from the locking member 210, so as to ensure that the locking member 210 will not slide along the axial direction of the connecting arm 322 of the galvanometer assembly 300, thereby ensuring the locking effect and reliability of the locking assembly 200.

[0072] In one possible implementation, the stop portion 130 includes a first stop surface 131 and a second stop surface 132. The first stop surface 131 abuts against the end face of the clamping member 220 away from the locking member 210, and the second stop surface 132 abuts against the outer peripheral surface of the end of the clamping member 220 away from the locking member 210. This allows the stop portion 130 to better push against the end of the clamping member 220 away from the locking member 210, ensuring the locking effect and reliability of the locking assembly 200.

[0073] In one possible implementation, a locking hole can be provided on the wall of the hole where the mounting hole 110 is threadedly connected to the locking member 210. After the locking member 210 is locked to the mounting hole 110, a top tightening member that abuts against the side wall of the locking member 210 can be provided in the locking hole to prevent the locking member 210 from loosening. The top tightening member can be a set screw.

[0074] In one possible implementation, the locking component 200 can be a glancing head.

[0075] In one possible implementation, the laser galvanometer module also includes a laser 400, which can be fixedly mounted on the mounting base 100 and can emit a laser beam toward the galvanometer 310.

[0076] Figure 10 This is a schematic diagram of the structure of the laser galvanometer module provided in this embodiment, where the galvanometer is oriented toward the mounting base.

[0077] Reference Figure 10 As shown, in one possible implementation, the laser galvanometer module is mounted on the camera housing. The laser galvanometer module also includes a mounting base 500 fixedly connected to the mounting base 100. The mounting base 500 is used to fix the module to the camera housing. The galvanometer 310 is positioned facing the mounting base 500, allowing the galvanometer 310 to be closer to the mounting base 500. This helps reduce the height of the laser galvanometer module in the direction from the mounting base 500 to the mounting base 100, thereby reducing the height of the camera housing in the same direction, or minimizing the space occupied by the laser galvanometer module within the camera housing. For example, the mounting base 100 and the mounting base 500 can be fastened together using screws or other fasteners, or the mounting base 100 and the mounting base 500 can be a single piece.

[0078] In one possible implementation, the mounting base 500 includes a base plate 510 and a support portion 520, with the support portion 520 disposed on the base plate 510. Exemplarily, the support portion 520 and the base plate 510 can be a single piece, or the support portion 520 and the base plate 510 can be fixedly connected by fasteners such as welding, snap-fitting, or screws. The mounting seat 100 is connected to the support portion 520. Exemplarily, the mounting seat 100 can be connected to the support portion 520 by fasteners such as welding, snap-fitting, or screws, or the mounting seat 100 and the support portion 520 can be a single piece.

[0079] In some examples, the side of the support portion 520 facing the mounting base 100 may protrude beyond the side of the base plate portion 510 facing the mounting base 100. In other examples, the side of the support portion 520 facing the mounting base 100 may be flush with the side of the base plate portion 510 facing the mounting base 100. When the side of the support portion 520 facing the mounting base 100 is flush with the side of the base plate portion 510 facing the mounting base 100, the height of the laser galvanometer module in the direction from the mounting base 500 to the mounting base 100 can be further reduced, which in turn helps to further reduce the height of the camera housing in the direction from the mounting base 500 to the mounting base 100, or helps to further reduce the space occupied by the laser galvanometer module in the camera housing.

[0080] In one possible implementation, the mounting base 100 includes a first mounting portion 111 and a second mounting portion 112 connected to each other. The first mounting portion 111 is correspondingly connected to the support portion 520. A positioning structure can be provided between the first mounting portion 111 and the support portion 520. For example, a positioning hole can be provided on the side of the first mounting portion 111 facing the support portion 520, and a positioning post can be provided on the side of the support portion 520 facing the first mounting portion 111. Alternatively, a positioning post can be provided on the side of the first mounting portion 111 facing the support portion 520, and a positioning hole can be provided on the side of the support portion 520 facing the first mounting portion 111. When the first mounting portion 111 and the support portion 520 are mated, the positioning post engages with the positioning hole. The second mounting portion 112 is spaced apart from the base plate portion 510. A drive motor 320 is mounted on the second mounting portion 112, and a galvanometer 310 is located between the second mounting portion 112 and the base plate portion 510. The distance between the galvanometer 310 and the base plate portion 510 can be adjusted according to actual needs.

[0081] In one possible implementation, a mounting hole 110 is provided on the second mounting portion 112, and at least a portion of the connecting arm 322 of the drive motor 320 passes through the mounting hole 110. Exemplarily, the mounting hole 110 may be formed by a clamping arm provided on the second mounting portion 112 and the second mounting portion 112 enclosing each other. The end of the clamping arm can be locked to the second mounting portion 112 by fasteners such as screws to ensure the reliability of the clamping arm and the second mounting portion 112 in clamping the device within the mounting hole 110. In other examples, the mounting hole 110 may be a hole provided on the second mounting portion 112, with the sidewalls of the mounting hole 110 closed circumferentially.

[0082] In one possible implementation, the laser 400 can be mounted on the first mounting portion 111. For example, a mounting groove can be provided on the side of the first mounting portion 111 facing the support portion 520. The laser 400 is mounted in the mounting groove. When the first mounting portion 111 and the support portion 520 are correspondingly connected, the support portion 520 blocks the opening of the mounting groove to ensure the reliability of the laser 400's mounting in the groove. A heat dissipation portion can be provided on the side of the first mounting portion 111 away from the support portion 520. The heat dissipation portion is used to dissipate heat from the laser 400, and the heat dissipation portion can be heat dissipation fins.

[0083] In one possible implementation, a protective baffle 113 extending toward the base plate 510 can be provided on the side of the second mounting portion 112 facing the base plate 510. The protective baffle 113 blocks a portion of the circumferential area of ​​the galvanometer 310, thereby preventing the laser beam emitted by the laser 400 from propagating in other directions. In some examples, the side of the protective baffle 113 facing the base plate 510 can be flush with the side of the first mounting portion 111 facing the support portion 520; in other examples, the side of the protective baffle 113 facing the base plate 510 can be recessed into the side of the first mounting portion 111 facing the support portion 520. This not only avoids interference between the protective baffle 113 and the base plate 510, affecting the installation of the mounting base 100 on the mounting base 500, but also limits the extension of the side of the protective baffle 113 facing the base plate 510, ensuring that the height of the laser galvanometer module does not increase.
