Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor lasers, and more specifically to a high-power laser for semiconductors. Background Art

[0002] Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as working materials. They have the advantages of low manufacturing cost, long service life, light weight, small size and high efficiency, making them an indispensable and important light source in communications, information storage, pump lasers, and an irreplaceable optical device in optoelectronic systems that require high-efficiency single-mode light sources.

[0003] Based on the above, the inventors found that when the existing high-power laser is in use, due to power problems, the internal components of the laser will generate a higher temperature, and the laser is generally installed on a base when in use, and the base lacks an effective heat dissipation structure, thereby affecting the normal operation of the laser. Therefore, in view of this, the existing structure is studied and improved to provide a high-power laser for semiconductors, in order to achieve a more practical purpose. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a high-power semiconductor laser. This solution can use air cooling to dissipate the heat generated by the laser during operation, and the cleaning component can clean the dust adhered to the filter to ensure the normal circulation of air. At the same time, the clamping component can automatically clamp the laser, which can improve the installation stability of the laser and reduce the problem of shaking and deviation of the laser during operation.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A high-power laser for semiconductors comprises a heat-conducting seat, a heat-absorbing plate is arranged directly above the heat-conducting seat, and a laser body is arranged at the front end of the opposite surfaces of the heat-conducting seat and the heat-absorbing plate, both sides of the heat-conducting seat are fixedly connected with air pumps at the rear end, and four telescopic tubes symmetrically arranged in pairs are arranged at the outer side of the opposite surfaces of the heat-conducting seat and the heat-absorbing plate, a clamping reinforcement mechanism is arranged at the side of the bottom surface of the heat-absorbing plate, and the rear end of the heat-absorbing plate is threadedly connected with threaded sleeves at both sides, one end of the threaded sleeve is fixedly connected with a filter screen, the middle part of the filter screen is movably connected with a rotating shaft, and one end of the rotating shaft is fixedly connected with a group of cleaning blades.

[0007] Furthermore, the clamping reinforcement mechanism includes two symmetrically arranged clamping blocks, the inner side of the clamping block is provided with a pressure surface, and the top surface of the clamping block is fixedly connected to a pair of sliding blocks, a guide rod is provided through the middle of the sliding block, and a clamping spring is fixedly connected to one side of the sliding block.

[0008] Furthermore, the telescopic tube is composed of two upper and lower sections that are slidably connected, and the top end of the upper section of the telescopic tube is fixedly connected to the heat absorbing plate, and the bottom end of the lower section of the telescopic tube is fixedly connected to the heat conducting seat.

[0009] Furthermore, the bottom end of the upper section of the telescopic tube is fixedly connected with an anti-slip ring, and the anti-slip ring is located inside the lower section of the telescopic tube.

[0010] Furthermore, the rotating shaft passes through the middle of the filter screen, and the cleaning blades are in contact with the outer side of the filter screen.

[0011] Furthermore, the sliding block is located inside the heat absorbing plate, and the sliding block is slidably connected to the heat absorbing plate.

[0012] Furthermore, the guide rod and the end of the clamping spring away from the sliding block are both fixedly connected to the inner surface of the heat absorbing plate.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] (1) This solution automatically adjusts the telescopic tube to maintain air circulation between the heat absorbing plate and the heat conducting seat. When the external cold air passes through the threaded sleeve and enters the heat absorbing plate, the filter screen filters the dust. At the same time, the air blows the cleaning blades to rotate along the rotating shaft to clean the dust adhered to the outside of the filter screen. Compared with the existing technology, the heat generated by the laser during operation can be cooled and dissipated, and the cleaning component can clean the dust adhered to the filter to ensure normal air circulation.

[0015] (2) By setting up a clamping reinforcement mechanism, during the installation process, the pressure surface on the inner side of the clamping block contacts the laser body, thereby squeezing the clamping block to move outward, thereby driving the sliding block to compress the clamping spring until the bottom surface of the heat absorbing plate fits with the top surface of the laser body. Under the reset force of the clamping spring, the sliding block drives the clamping block to reversely squeeze the side of the laser body. Compared with the existing technology, the laser is automatically clamped by the clamping assembly, which can improve the installation stability of the laser and reduce the problem of shaking and deviation of the laser during operation.

The top of the upper section of the telescopic tube 5 is fixedly connected to the heat absorbing plate 2, and the bottom of the lower section of the telescopic tube 5 is fixedly connected to the heat conducting seat 1. The telescopic tube 5 allows the heat absorbing plate 2 and the heat conducting seat 1 to maintain air circulation, so that air cooling and heat dissipation work can be performed normally.

[0025] See also Figure 3 The bottom end of the upper section of the telescopic tube 5 is fixedly connected with an anti-slip ring 11, and the anti-slip ring 11 is located inside the lower section of the telescopic tube 5. When the distance between the heat absorbing plate 2 and the heat conducting seat 1 is adjusted, the telescopic tube 5 is automatically telescoped and adjusted.

[0026] See also Figure 2 The rotating shaft 9 passes through the middle of the filter 8, and the cleaning blade 10 is fitted with the outer side of the filter 8.

The laser body 3 is placed in the center of the top surface of the heat conducting seat 1, and then the heat absorbing plate 2 is slid downward. During the movement of the heat absorbing plate 2, the pressure surface 13 on the inner side of the clamping block 12 contacts the laser body 3, thereby squeezing the clamping block 12 to move outward, thereby driving the sliding block 14 to compress the clamping spring 16.

[0029] When in use: place the laser body 3 on the top surface of the heat-conducting seat 1 in the center, then slide the heat-absorbing plate 2 downward, during the movement of the heat-absorbing plate 2, the pressure surface 13 inside the clamping block 12 contacts the laser body 3, and then squeezes the clamping block 12 to move outward, and then drives the sliding block 14 to compress the clamping spring 16 until the bottom surface of the heat-absorbing plate 2 fits the top surface of the laser body 3, under the reset force of the clamping spring 16, the sliding block 14 drives the clamping block 12 to reversely squeeze the side of the laser body 3, and then starts the laser body 3 for laser irradiation, and The heat generated during the working process is conducted and absorbed by the heat absorbing plate 2. At this time, the air pump 4 is started to allow the external cold air to enter the heat absorbing plate 2 through the threaded sleeve 7, driving the hot air inside the heat absorbing plate 2 to pass through the telescopic tube 5, and finally discharged from the air outlet end of the air pump 4 to complete the cooling work. At the same time, when the external cold air passes through the threaded sleeve 7 and enters the heat absorbing plate 2, the filter 8 filters the dust. At the same time, the air blows the cleaning blade 10, causing the cleaning blade 10 to rotate along the rotating shaft 9 to clean the dust adhered to the outside of the filter 8, thereby ensuring the normal circulation of the external cold air.
