Specifically, in this embodiment, the frame assembly 7 is used as a portion of the laser where the lens 2 is mounted, and the clamping fixture 1 is used as a structure for clamping and positioning the lens 2. A lens mounting hole 6 for mounting the lens 2 is formed on the frame assembly 7, an inner diameter of the lens mounting hole 6 is matched with an outer diameter of the lens 2, a lens mounting part 5 is formed in the lens mounting hole 6 in a radial direction, the lens mounting part 5 may be a mounting ring formed in the lens mounting hole 6, or a plurality of mounting bars formed in the lens mounting hole 6, the plurality of mounting bars being arranged along a circumferential direction of the lens mounting hole 6.
In order to improve the mounting stability of the lens 2, it is necessary to increase the contact area between the lens 2 and the lens mounting portion 5 as much as possible, and for this purpose, the lens mounting portion 5 in this embodiment is preferably a mounting ring formed in the lens mounting hole 6, and when the lens 2 is mounted in the lens mounting portion 5 in the axial direction, the edge of the end face of the lens 2 will abut against the end face of the lens 2 mounting ring. In this embodiment, an adhesive is applied to an end surface of the lens mounting portion 5 facing the lens 2, and the lens 2 can be adhesively fixed to the lens mounting portion 5 by the adhesive. The adhesive is an ultraviolet curing adhesive, and curing is achieved by irradiating ultraviolet rays after the lens 2 is mounted.
In order to prevent the angle of the lens 2 from changing during the process of mounting the lens 2 to the lens mounting hole 6 and during the process of curing the adhesive after the lens 2 contacts the adhesive, a specific clamping tool 1 is used to fix and position the lens 2 in this embodiment. As shown in fig. 1, the clamping fixture 1 comprises two clamping arms 101 which are oppositely arranged, and the clamping force can be provided between the two clamping arms 101 by utilizing elasticity or under the action of an additional fastener. A lens holding cavity 102 is formed between the two clamping arms 101, and the diameter of the lens holding cavity 102 is slightly larger than that of the lens 2, so that the lens 2 can be placed into the lens holding cavity 102 better. To improve the stability of the clamping, the lens clamping chamber 102 is approximately closed and circular, and two upwardly extending clamping arms 101 are formed at the notch. During installation, the lens 2 can be placed in the lens clamping cavity 102, the front end of the lens 2 protrudes out of the clamping tool 1, the lens 2 is clamped and positioned by the lens clamping cavity 102, then the clamping tool 1 is installed on the frame assembly 7 and is fixed by the connecting assembly, the protruding part of the lens 2 is inserted into the lens installation hole 6, the front end face of the lens 2 abuts against the end face of the lens installation part 5 in the lens installation hole 6, the adhesive coated on the end face of the lens installation part 5 is cured after contacting with the lens 2, the lens 2 is fixed in the lens installation hole 6, and finally the lens 2 can be installed after the clamping tool 1 is withdrawn.
Compared with the prior art, the application has the advantages that: by improving the bonding process of the lens 2, the problem of lens 2 angle change caused by small change in the bonding process of the lens 2 by using the adhesive is solved, the adjusting precision of the lens 2 of the laser is improved, and meanwhile, the method has the advantages of simple and efficient structure, low cost, rapid manufacturing and time saving, and is more convenient and convenient in the laser production and adjusting process.
In order to facilitate adjustment of the mounting angle of the lens 2 when the clamping fixture 1 and the frame assembly 7 are connected, the connecting assembly in this embodiment comprises a first adjusting bolt 4, a second adjusting bolt 8 and a third adjusting bolt 9;
the upper ends of the two clamping arms 101 face the mirror bracket assembly 7, the extension arms 1011 are provided with extension arms 1011, the extension arms 1011 can prop against the upper end surface of the mirror bracket assembly 7, and the first adjusting bolt 4 passes through the extension parts and is in threaded connection with the mirror bracket assembly 7;
the second adjusting bolt 8 and the third adjusting bolt 9 are arranged at the lower part of the clamping tool 1 and are positioned at two sides of the lens clamping cavity 102, and the second adjusting bolt 8 and the third adjusting bolt 9 penetrate through the clamping tool 1 and are in threaded connection with the lens holder assembly 7.
In this embodiment, the upper ends of the two arms 101 are formed with extension arms 1011 in the horizontal direction, and the extension arms 1011 extend toward the frame assembly 7 and form a substantially inverted L-shaped structure together with the two arms 101. During installation, the clamping tool 1 translates along the horizontal direction until the extension arms 1011 are stacked on the upper end surface of the frame assembly 7, and the end surface of the clamping arm 101 is close to the end surface of the frame assembly 7. The first adjustment bolt 4 is then threaded onto the extension arm 1011 and onto the upper end of the frame assembly 7, and the clamping fixture 1 can be made of a relatively soft material, such as aluminum. When the first adjusting bolt 4 is screwed to apply a greater pressure to the extension arm 1011, the two clamp arms 101 will bend upward about the point of application, thereby causing a change in the pitch angle of the lens 2 mounted between the two clamp arms 101, such that the mounting angle of the lens 2 can be such that the reflected beam returns substantially along the original optical path.
On the basis of adjusting the pitch angle of the lens 2 by the first adjusting bolt 4 in the connection assembly, the second adjusting bolt 8 and the third adjusting bolt 9 are further arranged on the clamp arm 101 for further fine-adjusting the left and right deflection angle of the lens 2 in this embodiment. The second and third adjusting bolts 8, 9 are located below the lens holding cavity 102 and on either side of the lens holding cavity 102. Taking the example that the second adjusting bolt 8 and the third adjusting bolt 9 are respectively positioned at the left side and the right side, the deflection angle of the lens 2 can be adjusted by adjusting the pressing force of the second adjusting bolt 8 and the third adjusting bolt 9 on the clamping arm 101. The pressure on the left side of the clamping arm 101 can be increased, for example, by screwing the second adjusting bolt 8, at which time the portion of the clamping fixture 1 located on the right side of the second adjusting bolt 8 will bend towards the left side, thereby deflecting the lens 2 mounted in the clamping fixture 1 towards the left side. The deflection of the lens 2 towards the right can be controlled by screwing the third adjusting bolt 9 in the same way. The angle of deflection of the lens 2 about the vertical axis can be varied during adjustment by means of the second adjusting bolt 8 and the third adjusting bolt 9 so that the return beam can completely coincide with the incident beam.
In order to form the lens clamping cavity 102 and better clamp and fix the lens 2, in this embodiment, a connection space 3 is provided between the extension arms 1011 of the two clamping arms 101, the first adjusting bolt 4 passes through the connection space 3 and is in threaded connection with the upper end of the frame assembly 7, the first adjusting bolt 4 can be pressed on the connection arm, and the pitching angle of the clamping arms 101 is adjusted by adjusting the pressing force of the first adjusting bolt 4.
Specifically, it should be noted that the width of the connection space 3 is approximately equal to the diameter of the first adjusting bolt 4 and is smaller than the diameter of the head end of the first adjusting bolt 4, so that the head end of the first adjusting bolt 4 can be pressed against the upper end surfaces of the two extension arms 1011 while passing through the connection space 3, and thus, the two extension arms 1011 can be pressed against each other by one first adjusting bolt 4.
In order to conveniently and replaceably adjust the deflection angle of the lens 2 around the vertical axis, the second adjusting bolt 8 and the third adjusting bolt 9 in the embodiment are symmetrically distributed along the vertical center line of the lens clamping cavity 102; the second adjusting bolt 8 and the third adjusting bolt 9 are pressed on the front side surface of the clamping tool 1, and the pitching angle of the clamping arm 101 and the deflection angle of the clamping arm 101 along the vertical axis are adjusted by adjusting the pressing force of the second adjusting bolt 8 and the third adjusting bolt 9.
In this embodiment, the frame assembly 7 includes a frame 71 base and a frame 71, the frame 71 is detachably fixed to the frame 71 base, and the lens mounting hole 6 is formed in the frame 71. The frame 71 serves as a part to be mounted into the laser and the base of the frame 71 serves as a base structure for fixing the frame 71 during the mounting of the lens 2. In order to facilitate the fixation of the frame 71, in this embodiment, mounting portions 72 are formed to extend outwards at two sides of the frame 71, and the mounting portions 72 are fixedly connected to the base of the frame 71 by connecting screws. The mounting portion 72 can be a portion of the frame 71, both of which are integrally formed.
In order to enable the lens 2 to be stably clamped between the two clamp arms 101, the two clamp arms 101 in the embodiment are connected by clamping screws, and clamping forces of the two clamp arms 101 can be adjusted by screwing the clamping screws. Before the lens 2 is mounted, the clamping screw is in a unscrewed state, and after the lens 2 is loaded into the lens clamping cavity 102, the clamping screw is tightened to enable the two clamping arms 101 to be close to each other, so that the lens 2 is clamped. The clamping screw may also be loosened during installation to adjust the mounting position of the lens 2 within the lens clamping cavity 102.
