Detailed Description
In order to make the objects, aspects and advantages of the embodiments of the present invention clearer, the following text will clearly and completely describe the embodiments of the present invention with reference to the schematic drawings of specific embodiments of the present invention. Unless otherwise indicated, terms used herein have the ordinary meaning in the art. Like reference symbols in the various drawings indicate like elements.
Fig. 1 shows a schematic diagram of a handheld laser welding apparatus, which mainly includes a laser light source 1, a collimator lens 2, a galvanometer 3, a galvanometer motor 4, a focusing lens 5, and the like. The laser light source 1 emits a divergent laser beam. The collimator lens 2 receives the divergent light beam and deflects it into a parallel light beam. The galvanometer 3 has a reflecting surface which is disposed in the optical path of the parallel light flux so as to be reflected at an angle. The focusing lens 5 receives the reflected parallel light beam, deflects it into a converging light beam and projects it onto the surface of the workpiece to be welded for heating, melting and welding the workpiece. The galvanometer motor 4 is connected to the galvanometer 5 and used for driving the galvanometer 3 to reciprocate around an axis X, and the oscillating galvanometer 3 enables the emergent direction of the laser beam to reciprocate along with the oscillating galvanometer so that the laser spot forms a welding seam with a certain width. In use, due to unexpected factors such as dropping and impact, the position of the galvanometer motor 4 may be shifted, so that the position of the galvanometer 3 is shifted to a set position, and the laser beam is dislocated or even cannot be normally emitted. Therefore, a galvanometer adjusting mechanism is required to be arranged in the handheld laser welding equipment to adjust the positions of the galvanometer motor 4 and the galvanometer 3.
Fig. 2 shows a cross-sectional view of a hand-held laser welding device with a galvanometer adjustment mechanism according to the invention. Fig. 2 shows a housing 6 of the device, the housing 6 having an inner cavity for accommodating therein the laser light source 1, the collimator lens 2, the galvanometer 3, the galvanometer motor 4, the focusing lens 5, and the like. As shown, the housing 6 has a motor mounting hole 61, which is substantially cylindrical, for mounting and fixing the galvanometer motor 4 therein. And a joint sleeve 7 is arranged between the galvanometer motor 4 and the hole wall of the motor mounting hole 61. The joint cover 7 is fixed to the galvanometer motor 4, and is rotatable with respect to the housing 6 with a joint portion 71 thereon as a support portion, thereby rotatably supporting the galvanometer motor 4. In addition, a plurality of adjusting screws 8 are provided on the housing 6 around the galvanometer motor 4, the inner end of each adjusting screw 8 can contact the joint sleeve 7, and the movement of the adjusting screw 8 can be converted into the rotation of the joint sleeve 7 and the galvanometer motor 4, so that the adjusting screws 8 can conveniently adjust the position and orientation of the galvanometer motor 4. The joint sleeve 7 and the adjusting screw 8 together constitute the galvanometer adjusting mechanism of the invention.
Fig. 3 shows a specific structure of the galvanometer motor 4 and the joint sleeve 7. The output end of the mirror motor 4 is provided with the mirror 3, and when the mirror motor 4 rotates, the mirror 3 can be driven to rotate, so that the direction of the laser beam can be adjusted. As shown in the figure, the galvanometer motor 4 has a first cylindrical portion 41 with a small diameter and a second cylindrical portion 42 with a large diameter, and the joint portion of the two forms an annular step surface 43. The first cylindrical portion 41 is closer to the end where the galvanometer 3 is mounted. The joint cover 7 is fitted and fixed to the outer side of the first cylindrical portion 41. The joint boot 7 is a substantially cylindrical member, the inner side surface of which is cylindrical, and is fixed to the outer surface of the first cylindrical portion 41 by interference fit or gluing, so that the joint boot 7 and the galvanometer motor 4 are fixed integrally and can move together. The middle position of the outer surface of the joint sleeve 7 forms a joint part 71 protruding outwards in the radial direction, the joint part 71 divides the cylindrical outer surface of the joint sleeve 7 into a front part 72 and a rear part 73, and the distance between the outermost side of the joint part 71 and the axis X of the galvanometer motor 4 is larger than the distance between the outermost side of the front part 72 and the outermost side of the rear part 73 and the axis X, so that the joint part 71 becomes the outer highest position of the joint sleeve 7.
As shown in fig. 3, the joint portion 71 has a circular-arc-shaped profile in a side sectional view (i.e., in a plane passing through the axis X), so that a circular-arc-shaped annular protrusion is formed on the outer surface of the joint boot 7, i.e., the protrusion extends continuously around one circumference of the joint boot 7. In another embodiment, not shown, the articulation 71 may be discontinuously extending, i.e. constituted by a plurality of segmented protruding points. In other embodiments not shown, the contour of the joint 71 may be other curves, such as elliptical, hyperbolic, etc. The joint boot 7 is made of a high polymer non-metallic material, which can be deformed so that an interference fit can be formed between the joint portion 71 of the joint boot 7 and the housing 6. One end of the joint boot 7 is positioned against the annular step surface 43 of the galvanometer motor 4, and the other end extends beyond the end of the first cylindrical portion 41 of the galvanometer motor 4, as shown in FIG. 3.
Referring to fig. 2, a partially enlarged view 4 shows a specific structure of the galvanometer adjustment mechanism. The galvanometer adjusting mechanism mainly comprises a joint sleeve 7 positioned outside the galvanometer motor 4 and an adjusting screw 8 arranged in the shell 6. The motor mounting hole 61 of the housing 6 and the galvanometer motor 4 are configured and dimensioned to fit each other. After the galvanometer motor 4 with the joint sleeve 7 is mounted on the housing 6, the first cylindrical portion 41 of the galvanometer motor 4 is positioned in the cylindrical motor mounting hole 61. The annular step surface 43 of the galvanometer motor 4 is over against the step surface at the edge of the inner side of the motor mounting hole 61, and a certain gap is formed between the annular step surface and the step surface, so that the galvanometer motor 4 can be prevented from being blocked during adjustment. The joint sleeve 7 is positioned between the first cylindrical part 41 and the inner surface of the motor mounting hole 61, and the joint part 71 of the joint sleeve 7 is in contact with the inner surface of the motor mounting hole 61 and forms an interference fit to prevent the galvanometer motor 4 from moving in the axial direction. The outer surfaces of the front and rear parts 72 and 73 of the joint cover 7 are not in contact with the inner surface of the motor mounting hole 61, but are spaced apart from each other by a gap, whereby the contact between the galvanometer motor 4 and the inner surface of the motor mounting hole 61 is made only at the projected joint part 71, so that the joint part 71 becomes a rotational support part of the galvanometer motor 4 with respect to the housing 6, that is, the galvanometer motor 4 can be rotated left and right and up and down with respect to the housing 6 with the joint part 71 as a support point, thereby making it possible to adjust the position and orientation of the galvanometer motor 4. Here, the adjustment "position" refers to adjusting the lateral position of the galvanometer motor 4 in translation in a plane perpendicular to the axis of the motor mounting hole 61, and the adjustment "orientation" refers to adjusting the angular orientation of the axis X of the galvanometer motor 4 with respect to the axis of the motor mounting hole 61.
The position of the galvanometer motor 4 is specifically adjusted by an adjusting screw 8. As shown in fig. 4, at positions of the housing 6 corresponding to the front part 72 and the rear part 73 of the joint boot 7, there are provided a front screw hole and a rear screw hole penetrating the wall of the housing 6 and communicating the outside and the motor mounting hole 61, respectively, which accommodate a front adjusting screw 81 and a rear adjusting screw 82, respectively. The front adjustment screw 81 and the rear adjustment screw 82 are each externally screwed into the corresponding screw hole. The distal end of the anterior adjustment screw 81 may contact the anterior portion 72 of the articular sleeve 7 and the distal end of the posterior adjustment screw 84 may contact the posterior portion 73 of the articular sleeve 7.
When the front adjustment screw 81 contacts and moves toward the galvanometer motor 4 (at this time, the rear adjustment screw 82 can be adjusted not to contact the joint sleeve 7), the galvanometer motor 4 can be driven to rotate counterclockwise around the joint part 71 of the joint sleeve 7; conversely, when the rear adjustment screw 82 contacts and moves toward the galvanometer motor 4 (at this time, the front adjustment screw 81 may be adjusted so as not to contact the joint sleeve 7), the galvanometer motor 4 may be driven to rotate clockwise around the joint portion 71 of the joint sleeve 7, whereby the orientation of the galvanometer motor 4 may be adjusted by controlling the screwed-in position of the front adjustment screw 81 or the rear adjustment screw 82.
When the front adjustment screw 81 and the rear adjustment screw 82 simultaneously contact and move toward the galvanometer motor 4, the galvanometer motor 4 as a whole can be driven to move to one side, whereby the position of the galvanometer motor 4 can be adjusted. Moreover, after the adjustment is completed, since the front and rear adjusting screws 81 and 82 contact and abut against the joint sleeve 7, the orientation and position of the galvanometer motor 4 can be restricted to be stably held in place.
In order to facilitate the adjustment of the position of the galvanometer motor 4, a plurality of sets of adjusting screws, preferably three sets of adjusting screws, may be symmetrically disposed around the galvanometer motor 4. Fig. 5 schematically shows the arrangement position and the operation principle of the adjusting screw 8, wherein the front circle and the rear circle represent the front section and the rear section of the connection part of the galvanometer motor 4 and the adjusting screw 8, the dotted line represents the axis of the galvanometer motor 4, and the triangle represents the rotation supporting part of the galvanometer motor 4 provided by the joint part 71. Fig. 5 shows three sets of 6 adjustment screws 8, each set of adjustment screws 8 comprising a front adjustment screw 81 located on the front side of the joint 71 and a rear adjustment screw 82 located on the rear side of the joint 71, the front adjustment screw 81 and the rear adjustment screw 82 being located at the same distance from the joint 71, whereby the same screw pushing force results in the same adjustment torque; the connection line between the contact portions of the front adjustment screw 81 and the rear adjustment screw 82 with the joint cover 7 is parallel to the axial direction of the galvanometer motor 4. As shown more clearly in the exploded view of FIG. 6, the first set of adjustment screws 81-1 and 82-1 are disposed at the top of the housing 6, the second set of adjustment screws 81-2 and 82-2 are disposed at the lower left portion of the housing 6, and the third set of adjustment screws 81-3 and 82-3 are disposed at the lower right portion of the housing 6, and preferably, the second set of adjustment screws 81-2 and 82-2 and the third set of adjustment screws 81-3 and 82-3 are bilaterally symmetrical. Since the top, lower left and lower right portions of the housing 6 are generally not blocked by other components of the hand-held laser welding apparatus, they can be easily reached by an operator, thereby facilitating the operation of the adjusting screw. Preferably, as shown in fig. 5, the three sets of adjustment screws 8 are symmetrically arranged in the circumferential direction around the axis of the motor mounting hole 61, i.e., 120 degrees apart from each other. Other angular arrangements are also possible.
When the galvanometer motor 4 is adjusted, the first front adjusting screw 81-1 is screwed in independently, so that the front part of the galvanometer motor 4 moves downwards, and the rear part moves upwards; conversely, screwing the first rear adjusting screw 82-1 alone can move the front portion of the galvanometer motor 4 upward and the rear portion downward, thereby adjusting the up-down orientation of the galvanometer motor 4 by adjusting the position of the first front adjusting screw 81-1 and/or the first rear adjusting screw 82-1.
When the galvanometer motor 4 is adjusted, the second front adjusting screw 81-2 is screwed in independently, so that the front part of the galvanometer motor 4 moves upwards to the right, and the rear part moves downwards to the left; conversely, the front part of the galvanometer motor 4 can move leftwards and downwards and the rear part can move rightwards and upwards by screwing the second rear adjusting screw 82-2; the third front adjusting screw 81-3 is screwed in independently, so that the front part of the galvanometer motor 4 can move upwards leftwards, and the rear part can move downwards rightwards; conversely, the front part of the galvanometer motor 4 can move downwards to the right and the rear part can move upwards to the left by screwing in the third rear adjusting screw 82-3 independently, so that the left-right orientation of the galvanometer motor 4 can be adjusted by adjusting the positions of the second front adjusting screw 81-2, the third front adjusting screw 81-3, the second rear adjusting screw 82-2 and/or the third rear adjusting screw 82-3.
When the galvanometer motor 4 is adjusted, the first front adjusting screw 81-1 and the first rear adjusting screw 82-1 are screwed in simultaneously or sequentially, so that the galvanometer motor 4 integrally moves downwards; simultaneously or sequentially screwing in the second front adjusting screw 81-2, the third front adjusting screw 81-3, the second rear adjusting screw 82-2 and the third rear adjusting screw 82-3 to enable the vibrating mirror motor 4 to integrally move upwards; simultaneously or sequentially screwing the second front adjusting screw 81-2 and the second rear adjusting screw 82-2, so that the whole galvanometer motor 4 moves rightwards; the third front adjusting screw 81-3 and the third rear adjusting screw 82-3 are screwed in simultaneously or sequentially, so that the galvanometer motor 4 integrally moves leftwards; thus, by adjusting the respective adjusting screws in a coordinated manner, the horizontal position of the galvanometer motor 4 can be adjusted up, down, left, and right.
In summary, by adjusting the positions of the 6 adjusting screws 8 in coordination, the position and orientation of the galvanometer motor 4 can be conveniently and flexibly adjusted, so that the galvanometer 3 coupled with the galvanometer motor 4 can be in the correct position and the position of the laser beam can be adjusted in a set manner.
In specific operation, the following exemplary manner may be used: first, all the adjustment screws 8 located on the same side (e.g., the rear side) of the joint portion 71 are released; then, one or more adjustment screws 8 located on the other side (e.g., the front side) of the joint portion 71 are adjusted; after the position and orientation of the galvanometer motor 4 are adjusted, the adjusting screw 8 on the side released previously is screwed to be in contact with the joint sleeve 7, so that the adjusting screws 8 on both sides of the joint portion 71 are all in contact with the joint sleeve 7, and the joint sleeve 7, the galvanometer motor 4, and the coupled galvanometer 3 can be stably maintained in the adjusted position.
By using the vibrating mirror adjusting mechanism, the position of the vibrating mirror can be conveniently adjusted on site, and the vibrating mirror deviation caused by vibration can be corrected. This kind of regulation can be realized through twisting the adjusting screw 8 of installing on casing 6 soon, need not to disassemble casing 6, and the operation is convenient, is showing the operating performance who has improved hand-held type laser welding equipment.
