Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor lasers, in particular to a semiconductor laser beam shaping lens mounting frame. Background Art

[0002] At present, semiconductor lasers are widely used in the fields of communication, industry and medicine. They are small in size and have high photoelectric conversion efficiency. Based on the characteristics of semiconductor lasers, the divergence angles of the output beam of semiconductor lasers in two mutually perpendicular planes are very different; therefore, the output beam needs to be shaped separately in two planes. The usual method is to use two cylindrical lenses, one in front and one behind, to shape them separately. Close to the laser chip is the fast-axis collimating lens. The fast-axis collimating lens is small in size, so it is necessary to fix the fast-axis collimating lens. The brackets or loading fixtures on both sides of the fast-axis collimating lens are bonded to the laser chip or the base under the chip to fix the fast-axis collimating lens.

[0003] Application number: CN202121545080.0, "A cylindrical lens device" When the U-groove bracket is connected to the cylindrical lens by glue, the glue is stored in the accommodating area, and the glue in the accommodating area forms a bonding surface connected to the cylindrical lens. In actual operation, the amount of glue used is increased, which is convenient for glue dispensers and other equipment to implement glue dispensing operations. In addition, the glue penetrates evenly and quickly inside the accommodating area, and the fixing efficiency of the cylindrical lens and the U-groove bracket is improved. The accommodating area increases the storage volume of the glue, making the glue slightly concave, or protruding or overflowing by no more than 0.02mm, effectively controlling the impact of the overflow glue on the light-passing area of ​​the cylindrical lens and the subsequent laser focusing, and improving the quality of gluing.

[0004] The cylindrical lens device described above connects the U-groove bracket and the cylindrical lens by glue, which makes it difficult to separate the U-groove bracket and the cylindrical lens, causing inconvenience to maintenance work such as replacing the lens later on the device.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-6 The utility model provides a technical solution: a semiconductor laser beam shaping lens mounting frame, comprising: a frame 4 for carrying a beam shaping lens 2, a connector 3 for connecting the beam shaping lens 2 and the frame 4 together, and a positioning component 1 for controlling the connection between the beam shaping lens 2 and the frame 4, wherein the positioning component 1 and the connector 3 are each provided with two groups.

[0025] The positioning assembly 1 includes: a pulling plate 11, a positioning rod 13 and a sliding block 15. One end of the positioning rod 13 is configured as a spherical surface 16 for easy insertion. The other end of the positioning rod 13 is fixedly connected to one side of the pulling plate 11. The outside of the positioning rod 13 is fixedly connected to the inner ring of the sliding block 15. The outside of the positioning rod 13 is also fixedly connected to the outside of the limit block 12. There are two groups of limit blocks 12. The two groups of limit blocks 12 are symmetrically arranged on the outside of the positioning rod 13; the outside of the positioning rod 13 is plugged into the inner ring of the return spring 14, and the return spring 14 is located between the limit block 12 and the sliding block 15.

[0026] A receiving groove 45 for receiving the beam shaping lens 2 and the connecting member 3 is provided at the top of the frame 4, the bottom of the receiving groove 45 is fixedly connected to the bottom of the protective pad 5, T-shaped slide grooves 44 are provided on both sides of the groove wall of the receiving groove 45, and square grooves 41, cavities 42 and circular grooves 43 are provided inside the two sides of the frame 4, and the square grooves 41, cavities 42, circular grooves 43 and T-shaped slide grooves 44 are connected in sequence.

[0027] Furthermore, before inserting the T-shaped slider 32 into the T-shaped slot 44, the pulling plate 11 is first pulled in the direction away from the frame body 4, and then the pulling plate 11 drives the positioning rod 13 to slide in the cavity 42, so that the spherical surface 16 end of the positioning rod 13 is pulled out of the T-shaped slot 44, so as to prevent the spherical surface 16 end of the positioning rod 13 from hindering the T-shaped slider 32 from being inserted into the T-shaped slot 44. At the same time, the positioning rod 13 will also drive the limit block 12 and the sliding block 15 to move in the direction of the pulling plate 11, so that the sliding block 15 compresses the return spring 14 and the limit block 12 moves out of the square groove 41. After the limit block 12 moves out of the square groove 41, the pulling plate 11 is rotated about 90 degrees, and the pulling plate 11 drives the limit block 12 to rotate about 90 degrees through the positioning rod 13, so that the limit The positioning block 12 is stuck on the outside of the frame 4 and cannot enter the square groove 41, so that the spherical surface 16 end of the positioning rod 13 cannot enter the T-shaped slide groove 44; then the T-shaped slider 32 can be inserted into the T-shaped slide groove 44, and the positioning hole 321 is aligned with the spherical surface 16 end of the positioning rod 13 after the T-shaped slider 32 is inserted. At this time, the pulling plate 11 is rotated about 90 degrees again so that the limit block 12 can enter the square groove 41, and then the return spring 14 pushes the sliding block 15 toward the positioning hole 321, and the sliding block 15 drives the positioning rod 13 to move toward the positioning hole 321, so that the spherical surface 16 end of the positioning rod 13 is inserted into the positioning hole 321, so that the T-shaped slider 32 cannot be withdrawn from the T-shaped slide groove 44, thereby realizing the installation and fixation of the beam shaping lens 2 and the frame 4.

[0028] The outside of the limiting block 12 is slidably connected to the wall of the square groove 41 , the wall of the cavity 42 is slidably sleeved on the outside of the positioning rod 13 , and the wall of the circular groove 43 is slidably sleeved on the outside of the sliding block 15 .

[0029] The return spring 14 is located in the circular groove 43 , and both ends of the return spring 14 are supported between the groove wall of the circular groove 43 and the outside of the sliding block 15 .

[0030] Furthermore, when the beam shaping lens 2 needs to be removed from the frame 4, it is only necessary to pull the pulling plate 11 in a direction away from the frame 4 so that the spherical surface 16 end of the positioning rod 13 is pulled out from the positioning hole 321, so that the T-shaped slider 32 can be pulled out from the T-shaped slide groove 44, thereby realizing the separation of the beam shaping lens 2 from the frame 4, making the disassembly and replacement of the beam shaping lens 2 more convenient for equipment maintenance.

[0031] The connecting member 3 includes: a connecting plate 31 and a T-shaped slider 32, the outer portion of the T-shaped slider 32 is slidably connected to the groove wall of the T-shaped slide groove 44, one side of the T-shaped slider 32 is fixedly connected to one side of the connecting plate 31, and the other side of the connecting plate 31 is fixedly connected to one end of the beam shaping lens 2.

[0032] A positioning hole 321 is formed at the side of the T-shaped slide block 32 , and the hole wall of the positioning hole 321 is slidably sleeved on the end of the positioning rod 13 .

[0033] Furthermore, the two ends of the beam shaping lens 2 are fixedly connected to one side of the connecting plate 31 to realize the combination of the beam shaping lens 2 and the entire connecting piece 3, and then the beam shaping lens 2 is movably connected to the frame 4 through the connecting piece 3 to facilitate the disassembly of the beam shaping lens 2.

[0034] Furthermore, the T-shaped slider 32 is inserted into the T-shaped slot 44, and then the outside of the positioning rod 13 is inserted into the cavity 42 and the positioning hole 321 at the same time, so that the T-shaped slider 32 and the frame 4 are fixed and cannot be separated. The positioning rod 13 is pulled out of the positioning hole 321, and the T-shaped slider 32 can be separated from the frame 4.

[0035] Working principle: When in use, the two ends of the beam shaping lens 2 are fixedly connected to one side of the connecting plate 31, so as to realize the combination of the beam shaping lens 2 and the entire connecting member 3; then the T-shaped slider 32 is inserted into the T-shaped slide groove 44. Before insertion, the pulling plate 11 is first pulled away from the frame 4, and then the pulling plate 11 drives the positioning rod 13 to slide in the cavity 42, so that the spherical surface 16 end of the positioning rod 13 is pulled out from the T-shaped slide groove 44, so as to prevent the spherical surface 16 end of the positioning rod 13 from hindering the T-shaped slider 32 from being inserted into the T-shaped slide groove 4 4, at the same time, the positioning rod 13 will also drive the limit block 12 and the sliding block 15 to move toward the direction of the pulling plate 11, so that the sliding block 15 compresses the return spring 14 and the limit block 12 moves out of the square groove 41. After the limit block 12 moves out of the square groove 41, the pulling plate 11 is rotated about 90 degrees, and the pulling plate 11 drives the limit block 12 to rotate about 90 degrees through the positioning rod 13, so that the limit block 12 is stuck on the outside of the frame 4 and cannot enter the square groove 41, thereby making the spherical surface 16 of the positioning rod 13 The end of the T-shaped slide block 32 cannot enter the T-shaped slide groove 44, and then the T-shaped slide block 32 can be inserted into the T-shaped slide groove 44. After the T-shaped slide block 32 is inserted, the positioning hole 321 is just aligned with the spherical surface 16 end of the positioning rod 13. At this time, the pulling plate 11 is rotated about 90 degrees again so that the limit block 12 can enter the square groove 41, and then the return spring 14 pushes the sliding block 15 toward the positioning hole 321, and the sliding block 15 drives the positioning rod 13 to move toward the positioning hole 321, so that the spherical surface 16 end of the positioning rod 13 is inserted into the positioning hole 321. In this way, the T-shaped slider 32 cannot be withdrawn from the T-shaped slot 44, thereby realizing the installation and fixation of the beam shaping lens 2 and the frame 4; when the beam shaping lens 2 needs to be removed from the frame 4, it is only necessary to pull the pulling plate 11 in a direction away from the frame 4, so that the spherical surface 16 end of the positioning rod 13 is withdrawn from the positioning hole 321, so that the T-shaped slider 32 can be withdrawn from the T-shaped slot 44, thereby realizing the separation of the beam shaping lens 2 and the frame 4, making the disassembly and replacement of the beam shaping lens 2 more convenient for equipment maintenance.
