A miniature laser diode mounting base

Abstract

This application discloses a miniature laser diode mounting base, relating to the field of laser diodes. It includes a mounting base, a laser diode body, and a lens. The mounting base is equipped with mounting components for fixing the laser diode body and the lens. This application utilizes the cooperative arrangement of structures such as a fixing ring, a fixing rod, and mounting rings. In use, the lens, abutment ring, and laser diode body are sequentially placed into the mounting base, with the mounting ring and abutment ring fitted onto the fixing rod. A pushing component pushes the mounting ring on the laser diode body, causing the mounting ring to push the abutment ring, which then abuts the mounting ring on the lens against the fixing ring. Simultaneously, two abutment rings abut against two mounting rings, fixing the lens and laser diode body within the mounting base. This design minimizes the risk of the lens shifting during use due to lack of fixation, which could cause the laser diode to move and reduce installation stability.

Description

Technical Field

[0001] This application relates to the field of laser diodes, and more particularly to a miniature laser diode mounting base. Background Technology

[0002] A diode can emit light as a function of the current flowing through it. For optical applications, a driver is provided to drive the diode, i.e., to supply current to the diode so that light can be emitted. Diode drivers vary depending on the requirements of different applications, system design, and the specifications and limitations of the circuitry providing the diode.

[0003] Utility model patent CN213660864U discloses a laser diode mounting base for a laser diode array module. The structure includes a lens, a mounting tube, and a laser diode. The lens and laser diode are inserted into the mounting tube from both ends and fixed in the mounting tube. Sealing rings are provided on the edges of the lens and the laser diode, so that they contact the inner wall of the mounting tube and form a sealed cavity between them. The cavity is evacuated to prevent the light generated by the laser diode from being scattered by the air. In addition, fixing rods pass through the two sealing rings, and the lens and laser diode are connected by the fixing rods to ensure the stability of the connection between them.

[0004] One of the laser diode mounting bases for a laser diode array module involves inserting a lens and a laser diode into the mounting tube from both ends. Then, a fixing rod is threaded through the sealing ring on the laser diode and connected to the sealing ring on the lens to connect the laser diode and the lens. A limiting block is used to prevent the laser diode from moving on the fixing rod. However, during use, the lens may not be fixed and may move, causing the laser diode to move as well, which reduces the stability of the installation. Utility Model Content

[0005] To address the aforementioned issues, this application provides a miniature laser diode mounting base.

[0006] The miniature laser diode mounting bracket provided in this application adopts the following technical solution:

[0007] A miniature laser diode mounting base includes a tube base, a laser diode body, and a lens. The tube base is provided with a mounting assembly for fixing the laser diode body and the lens. The mounting assembly includes a fixing ring fixedly connected to one end of the tube base. A plurality of fixing rods in a ring array are fixedly connected to one side wall of the fixing ring. Mounting rings are fixedly connected to the side walls of the laser diode body and the lens. The ends of the fixing rods away from the fixing rings pass through the mounting rings and are slidably arranged. Two abutment rings are provided between two mounting rings. The abutment rings are provided with an adjustment assembly for adjusting the spacing. The fixing rods are provided with a pushing assembly for pushing the mounting rings.

[0008] By adopting the above technical solution, during use, the lens is first placed into the tube socket, and the mounting ring is placed on the fixing rod. The lens is then passed through the fixing ring, causing the mounting ring to abut against the fixing ring. The distance between the two abutting rings is then adjusted using the adjusting component. The two abutting rings are then placed on the fixing rod. Next, the mounting ring with the laser diode body is placed on the fixing rod. The pushing component pushes the mounting ring on the laser diode body, causing the mounting ring to push the abutting rings, so that the two abutting rings abut against the two mounting rings respectively. This fixes the lens and laser diode body within the tube socket, minimizing the risk of the lens moving due to lack of fixation during use, which could cause the laser diode to move along with it and reduce installation stability.

[0009] Preferably, the adjusting assembly includes a plurality of adjusting tubes disposed between the two abutting rings, an adjusting rod slidably disposed inside the adjusting tube, the ends of the adjusting tubes opposite to the adjusting rods being fixedly connected to the abutting rings respectively, a fixing bolt being provided on the side wall of the adjusting tube away from the abutting rings, and a plurality of threaded holes being provided on the side wall of the adjusting rod, the screw end of the fixing bolt passing through the adjusting tube and being threadedly connected to the threaded holes.

[0010] By adopting the above technical solution, the adjusting rod is slid in the adjusting tube, and then the fixing bolt is threaded through the adjusting tube and connected to the threaded hole to fix the adjusting rod in the adjusting tube. By adjusting the distance between the two abutment rings, the distance between the laser diode body and the lens can be controlled as needed.

[0011] Preferably, the pushing assembly includes a plurality of pushing blocks that are threadedly connected to the fixed rod. One side wall of each pushing block has a plurality of annular array connecting grooves. A rotating tube is sleeved on the fixed rod, and one end of the rotating tube is fixedly connected to a plurality of connecting blocks that are adapted to the connecting grooves.

[0012] By adopting the above technical solution, after placing the laser diode body and lens into the tube socket, the push block is screwed into the fixed rod, and then the rotating tube is sleeved on the fixed rod, so that the connecting block is inserted into the connecting groove. The rotating tube drives the push block to rotate on the fixed rod, so that the push block abuts against the mounting ring, and pushes the mounting ring to move on the fixed rod, which facilitates fixing the laser diode body and lens in the tube socket.

[0013] Preferably, a connecting ring is fixedly connected to one end of the tube seat, and the connecting ring has multiple connecting holes for fixing on its side wall.

[0014] By adopting the above technical solution, the tube seat can be easily fixed through the connecting ring and connecting hole.

[0015] Preferably, a sealing ring is fixedly connected to the outer wall of the mounting ring, and the sealing ring is in contact with the inner wall of the tube seat.

[0016] By adopting the above technical solution, a sealed cavity can be formed between the lens and the laser diode body through the sealing ring. The cavity is evacuated, which can prevent the light generated by the laser diode body from being scattered by the air.

[0017] Preferably, the fixing rod is hollow, with an air hole on the side wall of the fixing rod near the fixing ring, and a sealing sleeve fitted on the end of the fixing rod away from the fixing ring.

[0018] By adopting the above technical solution, when the lens and the laser diode body are placed into the tube socket, the gas between the lens and the laser diode body can be discharged from the fixing rod through the air hole, which prevents the gas from being difficult to discharge when the laser diode body is close to the lens, thus preventing obstruction. At the same time, by connecting the external air extraction device to the fixing rod, it is convenient to evacuate the air between the lens and the laser diode body. Then, by putting a sealing sleeve on the fixing rod, gas can be prevented from entering.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. This application utilizes a combination of a fixing ring, a fixing rod, and a mounting ring. During use, the lens is first placed into the tube socket, and the mounting ring is then fitted onto the fixing rod. As the lens passes through the fixing ring, the mounting ring abuts against it. The distance between the two abutting rings is then adjusted using an adjusting assembly. The two abutting rings are then fitted onto the fixing rod. Next, the mounting ring with the laser diode body is fitted onto the fixing rod. A pushing assembly pushes the mounting ring on the laser diode body, causing the mounting ring to push the abutting rings, resulting in the two abutting rings abutting against the two mounting rings respectively. This fixes the lens and laser diode body within the tube socket, minimizing the risk of movement during use due to insufficient lens fixation, which could cause the laser diode to move along with it, reducing installation stability.

[0021] 2. When placing the lens and laser diode body into the tube socket, the gas between the lens and the laser diode body can be discharged from the fixing rod through the air hole, preventing the gas from being difficult to discharge when the laser diode body is close to the lens, thus preventing obstruction. At the same time, the external air extraction device is connected to the fixing rod to facilitate the evacuation of the air between the lens and the laser diode body. Then, by putting a sealing sleeve on the fixing rod, gas can be prevented from entering. Attached Figure Description

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0028] This application discloses a miniature laser diode mounting base.

[0029] Reference Figure 1 , Figure 2 and Figure 3 A miniature laser diode mounting base includes a tube base 1, a laser diode body 2, and a lens 3. The tube base 1 is provided with a mounting assembly for fixing the laser diode body 2 and the lens 3. The mounting assembly includes a fixing ring 4, a fixing rod 5, a mounting ring 6, and an abutment ring 7.

[0030] The fixing ring 4 is fixedly connected to one end inside the tube seat 1. Multiple fixing rods 5 are provided, all of which are fixedly connected to one side wall of the fixing ring 4 and form a ring array. Two mounting rings 6 are provided, which are fixedly connected to the side walls of the laser diode body 2 and the lens 3 respectively. The ends of the fixing rods 5 away from the fixing ring 4 pass through the mounting rings 6 and form a sliding arrangement. Two abutting rings 7 are provided, both located between two mounting rings 6. The abutting rings 7 are provided with adjustment components for adjusting the distance between the two abutting rings 7. The fixing rods 5 are provided with pushing components for pushing the mounting rings 6.

[0031] Reference Figure 1 and Figure 2 The adjustment assembly includes multiple adjustment tubes 8 disposed between two abutment rings 7. An adjustment rod 9 is slidably disposed inside the adjustment tube 8. The ends of the adjustment tubes 8 and the adjustment rods 9 opposite to each other are fixedly connected to the abutment rings 7. A fixing bolt 10 is provided on the side wall of the adjustment tube 8 away from the abutment rings 7. Multiple threaded holes 11 are opened on the side wall of the adjustment rod 9 at equal intervals. The screw end of the fixing bolt 10 passes through the adjustment tube 8 and is threadedly connected to the threaded hole 11. By sliding the adjustment rod 9 in the adjustment tube 8 and then threading the fixing bolt 10 through the adjustment tube 8 and threading it to the threaded hole 11, the adjustment rod 9 is fixed in the adjustment tube 8. The distance between the two abutment rings 7 can be adjusted, and the distance between the laser diode body 2 and the lens 3 can be controlled as needed.

[0032] Reference Figure 1 and Figure 3 The pushing assembly includes multiple pushing blocks 12 that are threaded onto the fixed rod 5. One side wall of each pushing block 12 has multiple annular array connecting grooves 13. A rotating tube 14 is fitted onto the fixed rod 5. One end of the rotating tube 14 is fixedly connected to multiple connecting blocks 15 that are adapted to the connecting grooves 13. After the laser diode body 2 and the lens 3 are placed into the tube seat 1, the pushing blocks 12 are screwed into the fixed rod 5, and then the rotating tube 14 is fitted onto the fixed rod 5, so that the connecting blocks 15 are inserted into the connecting grooves 13. The rotating tube 14 drives the pushing blocks 12 to rotate on the fixed rod 5, so that the pushing blocks 12 abut against the mounting ring 6, and pushes the mounting ring 6 to move on the fixed rod 5, so as to fix the laser diode body 2 and the lens 3 in the tube seat 1.

[0033] Reference Figure 1 A connecting ring 16 is fixedly connected to one side wall of the tube seat 1. The side wall of the connecting ring 16 has multiple connecting holes 17 for fixing. The tube seat 1 can be easily fixed through the connecting ring 16 and the connecting holes 17.

[0034] Reference Figure 1 A sealing ring 18 is fixedly connected to the outer wall of the mounting ring 6. The sealing ring 18 fits against the inner wall of the tube seat 1. The sealing ring 18 can form a sealed cavity between the lens 3 and the laser diode body 2. The cavity is evacuated to prevent the light generated by the laser diode body 2 from being scattered by the air.

[0035] Reference Figure 1 and Figure 4 The fixing rod 5 is hollow. An air hole 19 is opened on the side wall of the fixing rod 5 near the fixing ring 4. A sealing sleeve 20 is fitted on the end of the fixing rod 5 away from the fixing ring 4. When the lens 3 and the laser diode body 2 are placed into the tube seat 1, the gas between the lens 3 and the laser diode body 2 can be discharged from the fixing rod 5 through the air hole 19, preventing the gas from being difficult to discharge when the laser diode body 2 is close to the lens 3, thus preventing obstruction. At the same time, the external air extraction device is connected to the fixing rod 5 to facilitate the evacuation of the air between the lens 3 and the laser diode body 2. Then, by fitting the sealing sleeve 20 on the fixing rod 5, gas can be prevented from entering.

[0036] The implementation principle of a miniature laser diode mounting base according to an embodiment of this application is as follows: In use, first, the lens 3 is placed into the tube base 1, and the mounting ring 6 is fitted onto the fixing rod 5. Simultaneously, the lens 3 is passed through the fixing ring 4, causing the mounting ring 6 to abut against the fixing ring 4. Then, by sliding the adjusting rod 9 in the adjusting tube 8, the fixing bolt 10 is threaded through the adjusting tube 8 and connected to the threaded hole 11, fixing the adjusting rod 9 in the adjusting tube 8. The distance between the two abutting rings 7 is adjusted, and then the two abutting rings 7 are fitted onto the fixing rod 5. Afterwards, the mounting ring 6 with the laser diode body 2 is fitted onto the fixing rod 5, and then the mounting ring 6 is pushed... The moving block 12 is screwed into the fixed rod 5, and then the rotating tube 14 is sleeved on the fixed rod 5, so that the connecting block 15 is inserted into the connecting groove 13. The rotating tube 14 drives the pushing block 12 to rotate on the fixed rod 5, so that the pushing block 12 abuts against the mounting ring 6, pushing the mounting ring 6 to move on the fixed rod 5, so that the mounting ring 6 pushes the abutting ring 7, so that the two abutting rings 7 abut against the two mounting rings 6 respectively, fixing the lens 3 and the laser diode body 2 in the tube seat 1. This avoids the problem that the lens 3 may move due to lack of fixation during use, which may cause the laser diode to move as well, thus reducing the installation stability.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
