Problems solved by technology

However, there are the following defects in actual production: For the first method, the emitting sleeve needs to be welded to the circuit board of the light emitting device, which is not only inconvenient to operate, but also easy to burn the lens
For the second method, it is very easy to cause black glue to deface the lens
In addition, the solidification of black glue also takes time, which greatly reduces the production efficiency. Therefore, these two methods are not conducive to the collimation effect debugging of the coaxial transmission and reception scheme, resulting in low consistency of optical characteristics of the product

Embodiment 1

[0046] Such as Figure 1 to Figure 9 As shown, the first embodiment of the present invention provides a light source device, which is mainly composed of a light emitting device 1, a transmitting lens 3, a receiving lens 5, a transmitting sleeve 4, a light shielding component 7, and a supporting adjustment component 2, etc. . Wherein, the emitting sleeve 4 is used for setting the light emitting device 1 and making the emitting lens 3 and the receiving lens 5 coaxially arranged. The light-shielding component 7 is used to cover the bottom of the launch tube 4 so that the side wall of the launch tube 4 forms an opening area. The supporting adjusting part 2 is at least partially embedded in the emitting sleeve 4 through the opening area, and is used for supporting the light emitting device 1 and adjusting the position of the light emitting device 1 .

[0047] From the above, it can be seen that since the emitting sleeve 4 of the light source device in this embodiment can be used ...

Embodiment 2

[0068] The present application also provides a distance measuring device, including: the light source device in the first embodiment above.

[0069] From the above, it can be seen that the emitting sleeve 4 of the light source device of the distance measuring device provided in this embodiment can be used to set the light emitting device 1, and make the emitting lens 3 and the receiving lens 5 coaxially arranged, and by covering the light shielding member 7 After the bottom of the launch sleeve 4, the side wall of the launch sleeve 4 forms an opening area. At the same time, since the support adjustment part 2 can be embedded in the launch sleeve 4 through the opening area, the light-emitting device 1 is supported and fixed, so it can be adjusted by moving the support. The position of the component 2 can be used to adjust the position of the light emitting device 1 in the emitting sleeve 4, so as to facilitate the coaxial arrangement of the light emitting device 1, the emitting ...

Embodiment 3

[0072] This embodiment also provides a method for installing the light source device in any one of the above embodiments, such as Figure 11 shown, including the following steps:

[0073] Step S1: the transmitting lens 3 and the receiving lens 5 are coaxially arranged on the transmitting sleeve 4;

[0074] Step S2: After fixing the light-emitting device 1 on the support adjustment part 2, place it on the launch sleeve 4;

[0075] Step S3: Cover the bottom of the launch sleeve 4 with the light-shielding member 7, so that the side wall of the launch sleeve 4 forms an opening area that can slide and adjust the support adjustment member 2;

[0076] Step S4: After adjusting the light-emitting device 1 to a position coaxial with the emitting lens 3 and the receiving lens 5 by moving the supporting adjusting part 2, fix the supporting adjusting part 2.

[0077] Through the above steps, the assembly between the launch sleeve 4 in the light source device and the support adjustment pa...

Abstract

The invention aims to provide a light source device, distance measuring equipment and an installation method. The light source device is mainly composed of a light emitting device, a transmitting lens, a receiving lens, a transmitting sleeve, a shading component, a supporting and adjusting component and the like. The transmitting sleeve is used for arranging the light emitting device and enabling the transmitting lens and the receiving lens to be coaxially arranged. The shading component is used for covering the bottom of the transmitting sleeve, so that an opening area is formed on the side wall of the transmitting sleeve. At least part of the supporting and adjusting component is embedded into the transmitting sleeve through the opening area, and the supporting and adjusting component is used for supporting the light emitting device and adjusting the position of the light-emitting device. Compared with the prior art, light leakage in the back gap of the light emitting device can be avoided, and coaxial arrangement is facilitated.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a light source device, distance measuring equipment and an installation method. Background technique [0002] Distance measuring devices such as photoelectric rangefinders have attracted more and more attention from engineers because of their characteristics such as long distance measurement limit, high beam directivity, and fast response speed. [0003] Usually, the scheme of coincident the axis of emitted light and the axis of received light, that is, the coaxial scheme of sending and receiving is the scheme adopted by most photoelectric range finders. However, in actual use, since the light source in the light source device of the laser rangefinder must be on the same axis as the photosensitive device, and the distance between the two is very close, basically within a centimeter-level distance. However, in this case, if some or even weak components of the light emitted by the light sou...
