[0033] First embodiment

[0034] Please refer to Figure 1 and Figure 2 This embodiment provides a fixture 100 for use in the fabrication of a semiconductor laser. A semiconductor laser includes a housing, a laser chip, an optical assembly, and an optical fiber assembly. The fixture 100 in this embodiment is used to seal the end of the optical fiber assembly extending into the housing after the optical fiber assembly is mounted on the housing.

[0035] Specifically, a light through hole is provided on the shell. The optical fiber assembly extends into the light through hole from the outside of the shell so that the end of the optical fiber assembly is located in the light through hole. The laser chip and the optical assembly are located in the cavity on the inner side of the shell, and are used to inject laser into the light through hole for optical coupling. The fixture 100 in this embodiment is used to clamp the side wall of the shell where the light through hole is provided after the optical fiber assembly is installed, that is, after the optical fiber assembly is inserted into the light through hole, so as to seal the light through hole and prevent the optical fiber assembly from being contaminated. It is understandable that after the optical fiber assembly is contaminated, the laser chip and the lens of the optical assembly need to be repaired, and the lens may even be scrapped, which increases material loss, manpower investment, and cost. The fixture 100 of this embodiment can prevent the optical fiber assembly from being contaminated, thereby reducing the probability of repair of the semiconductor laser and reducing production costs.

[0036] The fixture 100 in this embodiment includes a first clamping plate 12 and a second clamping plate 22 spaced apart. A connecting portion 10 is provided between the first clamping plate 12 and the second clamping plate 22. Both ends of the connecting portion 10 are fixedly connected to the first clamping plate 12 and the second clamping plate 22, respectively.

[0037] By means of the first clamping plate 12 and the second clamping plate 22 which are arranged opposite to each other. The first clamping plate 12 and the second clamping plate 22 can clamp and install the shell position of the optical fiber assembly, thereby sealing the light-through hole of the shell. It can be understood that one end of the optical fiber assembly in this embodiment is inserted into the interior of the shell. A light-through hole for introducing laser light into the optical fiber assembly is provided on the inner wall of the shell. The first clamping plate 12 is used to abut against the inner wall of the shell, thereby closing the light-through hole. The second clamping plate 22 is used to abut against the outer wall of the shell. The first clamping plate 12 and the second clamping plate 22 are clamped on the shell to seal the light-through hole of the shell.

[0038] Furthermore, a sealing ring 13 is provided on the side of the first splint 12 facing the second splint 22 for sealing the light-through hole of the semiconductor laser. Specifically, the sealing ring 13 corresponds to the light-through hole of the shell. The sealing ring 13 protrudes from the surface of the first splint 12 facing the second splint 22. It can be understood that when the first splint 12 and the second splint 22 clamp the shell, when the first splint 12 fits against the inner wall of the shell, the sealing ring 13 is tightly attached to the shell due to its elastic force, achieving a tight fit, which can improve the sealing performance as much as possible. Preferably, the sealing ring 13 is made of a material that is not easy to adhere to dust, so as to prevent dust, impurities and other dirt from adhering to the sealing ring 13, thereby ensuring that the optical fiber assembly is not contaminated during the use or disassembly of the sealing ring 13.

[0039] Optionally, in this embodiment, the sealing ring 13 is circular, with a diameter greater than the diameter of the light-through hole. In other embodiments, the sealing ring 13 may be square or have other shapes. The present invention does not limit the shape of the sealing ring 13 as long as the light-through hole is located within the sealing ring 13 during sealing.

[0040] It should be understood that the present application does not limit the setting position of the sealing ring 13. Those skilled in the art can reasonably select the setting position of the sealing ring 13 according to the actual application scenario. It is only necessary to ensure that the through hole of the shell of the semiconductor laser can be sealed to achieve the technical effect of avoiding the contamination of the optical fiber component set in the sealing hole.

[0041] In this embodiment, a placement groove is provided on one side of the first clamping plate 12 facing the second clamping plate 22 , and the sealing ring 13 is embedded in the placement groove and fixedly connected to the first clamping plate 12 .

[0042] To facilitate dust collection, the first clamping plate 12 has a smooth surface on the side facing the second clamping plate 22. Specifically, in this embodiment, the surface of the first clamping plate 12 located within the sealing ring 13 is smooth because a non-smooth surface of the first clamping plate 12 located within the sealing ring 13 would easily harbor dirt, dust, impurities, and other contaminants, making them difficult to clean.

[0043] A fixing block 15 is provided on one side of the connecting portion 10 close to the first clamping plate 12. Two adjacent side surfaces of the fixing block 15 are fixedly connected to the connecting portion 10 and the first clamping plate 12 respectively. A groove 16 is provided on one side of the fixing block 15 close to the first clamping plate 12. It is understandable that when the shell is stepped, the setting of the fixing block 15 can ensure that it abuts against the shell in the height direction, thereby clamping to avoid misalignment. Grooves 16 are provided on the fixing block 15 to prevent the first clamping portion from abutting against the edges of other components to avoid failure to clamp. It should be understood that the purpose of the present application to provide grooves 16 on one side of the fixing block 15 close to the first clamping plate 12 is to adapt to the stepped shell to ensure that the fixing block 15 is adapted to abut against the shell. In actual applications, those skilled in the art can adaptively adjust the shape of the fixing block 15 according to the structure of the shell to ensure that the fixing block 15 abuts firmly against the shell.

[0044] Furthermore, a clearance opening 221 is formed on the second clamping plate 22. It is understood that the second clamping plate 22 is clamped to the outer wall of the housing, and the position of the clearance opening 221 corresponds to the position of the optical fiber assembly to ensure that the optical fiber assembly can pass through, thereby preventing the optical fiber assembly from being bent and damaged when the fixture 100 is clamped to the housing of the semiconductor laser.

[0045] Second embodiment

[0046] Please refer to Figure 3-Figure 6 The structure of the fixture 100 in this embodiment is substantially the same as that of the fixture 100 in the first embodiment, except that:

[0047] The connecting portion 10 in this embodiment includes a first connecting portion 11, a second connecting portion 21, and an adjustment assembly. The first connecting portion 11 is fixedly connected to the first clamping plate 12. The second connecting portion 21 is fixedly connected to the second clamping plate 22. The adjustment assembly is disposed between the first connecting portion 11 and the second connecting portion 21. The adjustment assembly is used to adjust the distance between the first connecting portion 11 and the second connecting portion 21. It will be understood that the adjustment assembly is used to adjust the distance between the first clamping plate 12 and the second clamping plate 22 to accommodate housings of varying thicknesses.

[0048] In this embodiment, the width of the first clamping plate 12 is smaller than the width of the first connecting portion 11. In other embodiments, the width of the first clamping plate 12 can be equal to the width of the first connecting portion 11. As long as the first clamping plate 12 can completely cover the light hole of the housing, this is not a limitation of the present invention.

[0049] In order to prevent the positions of the first clamping plate 12 and the second clamping plate 22 from being offset, in this embodiment, a guide mechanism is further provided between the first connecting portion 11 and the second connecting portion 21 .

[0050] Specifically, the guide mechanism includes a guide post 31 and a guide hole. The guide post 31 is fixedly connected to the second connecting portion 21. The guide hole is formed in the first connecting portion 11. The guide post 31 and the guide hole are slidably engaged. One end of the guide post 31 is inserted into the guide hole and can move along the axis of the guide hole.

[0051] Optionally, in this embodiment, one end of the guide post 31 is fixed to the second connection portion 21, and the other end is slidably connected to the first connection portion 11. In other embodiments, one end of the guide post 31 may be slidably connected to the second connection portion 21, and the other end may be fixed to the first connection portion 11. This is not a limitation of the present invention as long as the first clamping portion and the second clamping portion can move along the guide post 31.

[0052] It should be understood that the present application does not impose any restrictions on the connection and coordination between the guide post 31 and the first connecting portion 11. It is sufficient to ensure that when the first connecting portion 11 and the second connecting portion 21 move relative to each other, the movement of the first connecting portion 11 or the second connecting portion 21 remains stable and the movement path does not deviate. Those skilled in the art may select a movable connection method, such as a threaded connection, based on the actual application scenario.

[0053] In other embodiments, the guide mechanism may also be configured as a pneumatic cylinder, an electric cylinder, or the like.

[0054] In this embodiment, there are two guide posts 31, one on each side of the adjustment assembly. In other embodiments, the number of guide posts 31 may be one or more. The guide posts 31 may also be arranged in different planes, as long as the first clamping portion and the second clamping portion can move along the guide posts 31. This is not a limitation of the present invention.

[0055] In this embodiment, an elastic member 32 is further connected between the first connecting portion 11 and the second connecting portion 21. Specifically, the elastic member 32 is a spring, which is sleeved on the guide column 31. It can be understood that the provision of the elastic member 32 facilitates the resetting of the fixture 100. In other embodiments, the elastic member 32 can also be provided on the outside of the guide column 31, which is not limited in the present invention. In this embodiment, the elastic member 32 is sleeved on the guide column 31. In addition to achieving a shock-absorbing and buffering effect and absorbing the vibration and impact force generated during the relative movement of the first connecting portion 11 and the second connecting portion 21, it can also improve the damping performance of the guide column 31 and extend the service life of the guide column 31.

[0056] Furthermore, the adjustment assembly includes a screw 30. One end of the screw 30 is threadedly connected to the second connecting portion 21. The other end of the screw 30 is rotatably connected to the first connecting portion 11. Specifically, the screw 30 can be rotatably connected to the first connecting portion 11 via a bearing. The second connecting portion 21 is provided with a threaded through hole that mates with the screw 30. It will be understood that by rotating the screw 30 in the forward or reverse direction, the first clamping portion and the second clamping portion can be moved closer or farther away.

[0057] Furthermore, in order to facilitate the rotation of the screw rod 30 , one end of the screw rod 30 close to the second connecting portion 21 extends out of the second connecting portion 21 and is connected to a knob 33 at the end.

[0058] In summary, the beneficial effects of the semiconductor module fixture 100 provided by the embodiment of the present invention are:

[0059] The fixture 100 of the present invention includes a first clamping part and a second clamping part. The first clamping part includes a first connecting part 11 and a first clamping plate 12 fixedly connected to the first connecting part 11. The second clamping part includes a second connecting part 21 and a second clamping plate 22 fixedly connected to the second connecting part 21. The first clamping plate 12 and the second clamping plate 22 are arranged opposite to each other. An adjustment component is connected between the first connecting part 11 and the second connecting part 21. The adjustment component is used to adjust the distance between the first clamping part and the second clamping part. A sealing ring 13 is provided on the side of the first clamping plate 12 facing the second clamping plate 22.

[0060] The present invention utilizes a first clamping plate 12 and a second clamping plate 22 disposed relative to each other. The first and second clamping plates 12 and 22 can clamp the housing where the optical fiber assembly is mounted, and the sealing ring 13 corresponds to the light aperture of the housing, thereby sealing the light aperture of the housing. The present invention can seal the light aperture during the baking and transfer of the semiconductor laser module, preventing dust from entering the light aperture within the housing, protecting the optical fiber assembly from contamination, improving production efficiency, and reducing the return rate of laser internal lenses, thereby lowering costs.

[0061] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
