Description

Technical Field

[0001] The present invention relates to the technical field of laser emission devices, and particularly to an adjustable galvanometer laser emission device. Background Art

[0002] A galvanometer laser emitter mainly consists of a fixed frame, a galvanometer, and a laser emitter. The galvanometer is fixed on the fixed frame; the laser emitter is fixed on the galvanometer and is optically connected to the galvanometer. In practical applications, the galvanometer deflects the laser beam emitted by the laser emitter, enabling dynamic scanning and expanding the laser scanning area.

[0003] Currently, the processing precision of the fixed frame, galvanometer, and laser emitter is limited. Glue assistance is required for the screw locking positions to improve the fastening precision. However, in extremely complex situations or after being subjected to a certain degree of external force impact, the glue at the screw locking positions will shrink, and the locking screws between the fixed frame, galvanometer, and laser emitter will become loose, resulting in unstable emission angles of the laser beam deflected by the galvanometer, a large error in angle calculation, deviation from the objective lens target center, and affecting the scanning precision.

[0004] Therefore, how to design a galvanometer laser emitter with a simple structure, easy operation, firm connection, not easily loosened, and adjustable at multiple angles is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] The present invention provides an adjustable galvanometer laser emission device to solve the technical problem that the laser emission angle deviates from the objective lens target center after the screws of the existing galvanometer laser emitter become loose.

[0006] The technical solution of the present invention to solve the above technical problems is as follows. An adjustable galvanometer laser emission device includes: a laser emitter and a galvanometer, the laser emitter is fixed on the galvanometer and is optically connected to the galvanometer; it further includes: a fixed frame, a lens ring, a moving part, an X-axis bolt, and a Z-axis bolt.

[0007] The coronal axis of the fixing bracket is the X-axis, the sagittal axis is the Y-axis, and the vertical axis is the Z-axis. The fixing bracket is provided with a mirror hole, an adjustment hole, a long hole, and a screw hole A. The mirror hole and the adjustment hole are spaced along the Y-axis direction and are both arranged along the Y-axis direction. The inner hole surface of the mirror hole is a concave arc surface with an arc arranged axially. The long hole and the screw hole A are both arranged along the X-axis and are both communicated with the adjustment hole. The galvanometer is located between the mirror hole and the adjustment hole. The mirror ring is detachably sleeved outside one end of the galvanometer, and its outer ring surface is a convex arc surface with an arc arranged axially, and its convex arc surface rolls inside the concave arc surface. The moving part is located in the adjustment hole and is fixed to the other end of the galvanometer. The moving part is provided with a screw hole B arranged along the Z-axis direction and opposite to the long hole. The X-axis bolt is screwed into the screw hole A to contact the moving part to adjust the swing angle of the galvanometer in the X-axis direction. The Z-axis bolt slides through the long hole and is screwed into the screw hole B to adjust the pitching angle of the galvanometer in the Z-axis direction.

[0008] The beneficial effects of the present invention are as follows: The structure of the traditional galvanometer laser emitter is improved. First, the mirror ring is detachably sleeved outside one end of the galvanometer, and then the moving part is fixed to the other end of the galvanometer. Since the convex arc surface of the mirror ring rolls inside the concave arc surface of the mirror hole of the fixing bracket, and since the X-axis bolt is screwed into the screw hole A to contact the moving part and the Z-axis bolt slides through the long hole and is screwed into the screw hole B, it is possible to take the connection point of the rolling connection between the convex arc surface and the concave arc surface as the origin to adjust the swing angle of the galvanometer in the X-axis direction and the pitching angle in the Z-axis direction, align the objective lens bull's-eye, and improve the scanning accuracy.

[0009] On the basis of the above technical solutions, the present invention can be further improved as follows.

[0010] Further, the fixing bracket includes a fixing plate, an outer fixing ring, an inner fixing ring, and an adjustment bracket. The coronal axis of the fixing plate is the X-axis, the sagittal axis is the Y-axis, and the vertical axis is the Z-axis. The outer fixing ring is arranged along the X-axis direction, and its outer ring wall is fixed on the fixing plate. The inner fixing ring is detachably inserted into the outer fixing ring. The adjustment bracket is spaced on one side of the outer fixing ring corresponding to the Y-axis direction and is fixed on the fixing plate. The mirror hole is the inner ring hole of the inner fixing ring. The adjustment hole, the long hole, and the screw hole A are all arranged on the adjustment bracket.

[0011] Furthermore, the fixing frame also includes a clamping ring, a locking ring and a plurality of locking bolts, and one end of the outer fixing ring corresponding to the galvanometer is provided with a plurality of screw holes C spaced apart along the circumferential direction; the clamping ring is slidably sleeved on the outside of the mirror ring and extends into the outer fixing ring, and the extending end of the clamping ring extending into the outer fixing ring can contact the inner fixing ring; the locking ring is located on the side of the clamping ring corresponding to the galvanometer and a plurality of screw holes D arranged along the circumferential direction are provided on its ring wall, and the plurality of screw holes D are respectively arranged opposite to the plurality of screw holes C; the plurality of locking bolts are respectively screwed into the relatively arranged screw holes C and the screw holes D in sequence to push the locking ring to squeeze the clamping ring, so that the clamping ring slides outside the mirror ring, elastically expands the clamping ring, and holds the mirror ring tightly.

[0012] A further beneficial effect of the above-mentioned method is that the clamping ring is slidably sleeved on the outside of the mirror ring. When the locking ring pushes the clamping ring into the outer fixed ring, since the outer ring surface of the mirror ring is an outer convex arc surface arranged along the axial direction, the outer convex arc surface will elastically open the clamping ring, so that the clamping ring hugs the mirror ring and locks the mirror ring in a fixed position.

[0013] Furthermore, the clamping ring includes a first strip and a second strip, both of which are arc-shaped structures. The first strip and the second strip have the same arc direction and are relatively slidably sleeved on the outside of the mirror ring. The first strip and the second strip both extend into the outer fixed ring and the extended ends thereof extending into the outer fixed ring can contact the inner fixed ring. Both ends of the arc direction of the first strip are fixed with blocking blocks arranged opposite to each other at intervals. Both ends of the arc direction of the second strip are fixed with connecting rods, and limiting blocks are fixed on the two connecting rods. The two connecting rods are respectively inserted between the corresponding two blocking blocks and the corresponding limiting blocks can contact the corresponding two blocking blocks, so as to open the first strip and the second strip and hold the mirror ring tightly as pushed by the locking ring.

[0014] A further beneficial effect of adopting the above method is that the clamping ring is designed to be a first strip and a second strip arranged opposite to each other. Since the connecting rod is inserted between the two corresponding blocking blocks, after the mirror ring elastically stretches the first strip and the second strip, the limit block can contact the two blocking blocks to generate a rebound force, thereby holding the mirror ring tightly and locking the mirror ring in a fixed position.

[0015] Furthermore, the adjustment bracket is provided with a long slide groove arranged along the X-axis direction; the long hole is provided at the bottom of the long slide groove; the Z-axis bolt extends into the long slide groove and its screw end slides through the long hole.

[0016] Furthermore, the screw holes A and the X-axis bolts are two arranged opposite to each other, and the two screw holes A are distributed on both sides of the adjustment hole corresponding to the X-axis direction; the screw-in ends of the two X-axis bolts screwed into the corresponding screw holes A can be switched to contact with the moving part.

[0017] The further beneficial effects of the above are as follows: By arranging two X-axis bolts on both sides of the moving part corresponding to the X-axis, the swing angle of the moving part in the X-axis direction can be adjusted more conveniently.

[0018] Furthermore, the moving part includes a swing arm and an adjustment block. The swing arm is located between the mirror hole and the adjustment hole and is fixed on the galvanometer; the adjustment block is located in the adjustment hole and is fixed on the swing arm; the screw hole B is provided on the adjustment block.

[0019] Furthermore, the galvanometer includes a galvanometer housing, an incident mirror, a relay mirror, an exit mirror, and a MEMS module. The galvanometer housing is located between the mirror hole and the adjustment hole, and an exit hole is provided at one end corresponding to the mirror hole, and an incident hole is provided at the top corresponding to the Z-axis direction.

[0020] Furthermore, the laser emitter includes a protective housing and a diode. The protective housing is fixed on the galvanometer housing and is provided with a laser emission hole arranged opposite to the incident hole; the diode is fixed inside the protective housing corresponding to the laser emission hole.
