[0044] In order to solve the above technical problems, an embodiment of the utility model provides a fixing device 100 for a laser emitter. The fixing device 100 for a laser emitter is described in detail below.

[0045] See also Figure 1 , Figure 1 FIG. 1 is a schematic diagram of a structure of a fixing device 100 for a laser transmitter provided in an embodiment of the present utility model. Figure 1 As shown, the laser emitter fixing device 100 comprises: a laser emitter 110, a fixing assembly 120 and a locking assembly 130;

[0046] Among them, the fixing assembly 120 provided in this embodiment may include a first fixing structure 121 and a second fixing structure 122, the first fixing structure 121 is fixedly connected to the laser emitter 110 to fix the laser emitter 110 in the fixing assembly 120; the second fixing structure 122 is movably connected to the locking assembly 130 to allow the laser emitter 110 to perform angle fine-tuning; the locking assembly 130 is provided with a locking structure 131, and the locking structure 131 is used to lock the fixing assembly 120 in the locking assembly 130 after the laser emitter 110 completes angle fine-tuning.

[0048] In some embodiments, the first fixing structure 121 provided in this embodiment can be connected to the laser emitter 110 by glue, so as to add a layer of protection barrier to the laser emitter 110, and the internal structure of the laser emitter 110 will not be damaged when the laser emitter 110 is fixed.

[0049] In other embodiments, the laser emitter 110 provided in this embodiment may be provided with an alignment structure 111, and the first fixed structure 121 may be provided with a matching structure 1211. The laser emitter 110 can be fixed in the fixed assembly 120 by the mutual matching connection between the alignment structure 111 and the matching structure 1211.

[0050] For details, see Figure 2 , Figure 3 as well as Figure 4 , Figure 2-Figure 4 The laser emitter 110, the fixing assembly 120, and a schematic diagram of the laser emitter 110 and the fixing assembly 120 being fixedly connected are shown, wherein: Figure 2This is a schematic diagram of the structure of a laser transmitter provided by an embodiment of the utility model. Figure 3 is a structural schematic diagram of a fixing assembly provided in an embodiment of the utility model, Figure 4 It is a structural schematic diagram of a laser transmitter provided in an embodiment of the utility model being fixed in a fixing component.

[0051] like Figure 2-Figure 4 As shown, the alignment structure 111 provided on the laser emitter 110 provided in this embodiment may be a concave structure, and the matching structure 1211 provided on the fixing assembly 120 may be a convex structure. The fixing assembly 120 provided in this embodiment may have a circular cross-section, and a fixing groove 121 (first fixing structure) is provided inside for fixing the laser emitter 110 single tube. The convex structure is provided on the top of the fixing groove 121 for orientation reference, so as to cooperate and connect with the alignment structure 111 provided on the laser emitter 110. In this way, the purpose of fixing the laser emitter 110 in the fixing assembly 120 can be achieved through the alignment structure 111 provided on the laser emitter 110 and the matching structure 1211 provided on the fixing assembly 120.

[0052] It should be noted that the number of alignment structures 111 provided on the laser emitter 110 provided in this embodiment may be one or more, and the matching structures 1211 provided on the fixing component 120 corresponds to the number of alignment structures 111 on the laser emitter 110 .

[0053] Among them, the width of the contact support surface between the fixed groove 121 provided in this embodiment and the laser emitter 110 can be 1 mm, and the width of the contact support surface can also be 0.8, 1.5 mm, etc., which are not less than 0.5 mm. The specific value can be set according to actual needs and is not specifically limited here.

[0054] Please continue to see Figure 1 In an embodiment of the utility model, the locking assembly 130 provided in this embodiment includes at least one accommodating structure 132, and each of the accommodating structures 132 is provided with the locking structure 131; the accommodating structure 132 is movably connected with the second fixing structure 122 so that the fixing assembly 120 can be embedded and installed; the locking structure 131 is used to lock the fixing assembly 120 in the accommodating structure 132.

[0055] By movably connecting the containing structure 132 with the second fixed structure 122, it is possible to facilitate fine-tuning of the angle of the fixing component 120 and the laser emitter 110 as a whole, thereby achieving the purpose of fine-tuning the angle of the laser emitter 110; then, after completing the fine-tuning of the angle of the laser emitter 110, the fixing component 120 is locked in the containing structure 132 by the locking structure 131, so that the laser emission angle of the laser emitter 110 after the laser fine-tuning can be fixed, thereby effectively improving the efficiency of fixing the laser emitter 110.

[0056] As an optional embodiment of the utility model, the accommodating structure 132 provided in this embodiment can be a groove structure. Since the fixing assembly 120 provided in this embodiment is provided with a fixing groove 121 for fixing the laser emitter 110 single tube, the second fixing structure 122 of the fixing assembly 120 can be as follows: Figure 3 The figure shows the annular side wall 122 of the fixing groove 121 of the fixing assembly 120. In this way, by embedding the annular side wall 122 into the groove structure, the movable connection between the fixing assembly 120 and the locking assembly 130 can be achieved, so that the fixing assembly 120 and the laser emitter 110 can be finely adjusted in angle in the groove structure, thereby achieving the purpose of finely adjusting the angle of the laser emitter 110.

[0057] Among them, the annular side wall 122 of the fixing component 120 provided in this embodiment is not fully embedded in the groove structure, but a part of the annular side wall 122 of the fixing component 120 is retained outside, that is, a part of the annular side wall 122 of the fixing component 120 is exposed outside the groove structure, so that it is convenient for the staff to move the exposed annular side wall 122 to achieve the purpose of fine-tuning the angle of the fixing component 120 and the laser emitter 110 as a whole in the groove structure.

[0058] In addition, please continue to see Figure 2 The laser emitter 110 provided in this embodiment may further include a feeler structure 112, which is disposed on the side opposite to the lens of the laser emitter 110, and after the laser emitter 110 is fixed to the fixing assembly 120, the feeler structure 112 is still exposed outside the fixing assembly 120. In this way, when the annular side wall 122 of the fixing assembly 120 is embedded in the groove structure, by moving the feeler structure 112 exposed outside the fixing assembly 120, the purpose of fine-tuning the angle of the fixing assembly 120 and the laser emitter 110 as a whole in the groove structure can also be achieved.

[0059] It should be noted that the antenna structure 112 provided in this embodiment can not only be used as an adjustment structure for fine-tuning the angle of the laser emitter 110, but also can be the connection contact angle of the laser emitter 110 connected to the power supply. Therefore, when the laser emitter 110 provided in this embodiment is not connected to the power supply, the antenna structure 112 or the annular side wall 122 exposed outside the groove structure can be moved to achieve fine-tuning of the angle of the laser emitter 110; after the laser emitter 110 provided in this embodiment is connected to the power supply, the annular side wall 122 exposed outside the groove structure can be moved to achieve fine-tuning of the angle of the laser emitter 110. In this way, regardless of whether the laser emitter 110 is connected to the power supply, the fixing device 100 of the laser emitter provided in this embodiment can achieve fine-tuning of the angle of the laser emitter 110, so that the laser emitter 110 can be coupled during the test process and has the purpose of installation reliability.

Specifically, the threaded hole can be of a diameter such as M2, M3, or M5, and the specific size is adapted to the annular side wall 122 of the fixing assembly 120, and the screw is adapted to the threaded hole.

[0062] In some embodiments, the locking structure 131 provided in this embodiment may not include a locking piece, and the fixing assembly 120 may be locked in the containing structure 132 by only injecting glue into the through hole 1311 .

[0063] Please continue to see Figure 1 The laser emitter fixing device 100 provided in this embodiment may further include a lens 140, a ceramic sheet 150 and a platform 160; the lens 140 is arranged corresponding to the light outlet of the laser emitter 110; the ceramic sheet 150 is bonded to the platform 160, the lens 140 is bonded to the ceramic sheet 150, and the ceramic sheet 150 is arranged parallel to the laser emitted by the laser emitter 110.

[0064] The number of the lenses 140 may be one or more, which may be specifically set according to actual technical requirements. The placement position of the lenses 140 may also be set according to actual technical requirements, which is not specifically limited here.

Figure 5 As shown, the laser emitter fixing device 100 provided in this embodiment can fix multiple laser emitters 110 , thereby meeting the test work required for multiple laser emitters 110 .

[0066] In this embodiment, the locking assembly provided in this embodiment includes a plurality of accommodating structures, and the plurality of accommodating structures may not be at the same height, for example, a stepped structure such as Figure 5 As shown, the platform and ceramic sheet provided in this embodiment can be multiple and adapted to different containing structures to meet the test work of laser emitters in different containing structures; at the same time, multiple containing structures can also be at the same height at the same time, that is, the platform and ceramic sheet provided in this embodiment can be one.
