Problems solved by technology

During the assembly process of the structured light 3D module, it is necessary to fix the structured light camera, the structured light projector and the RGB camera on the same assembly bracket, such as figure 1 As shown, the assembly bracket of the structured light 3D module is a "me"-shaped structure with three assembly frames. This assembly bracket is long and takes up a lot of space, which is not conducive to miniaturization and thinning. The projector and RGB camera can only be assembled from above or below the corresponding assembly frame during assembly, and the assembly frame sometimes has structural interference with the components of the structured light 3D module due to size mismatch

Embodiment 1

[0037] Such as figure 2 and 3 As shown, an assembly bracket for a structured light 3D module has a first assembly frame A for assembling a structured light camera, a second assembly frame B for assembling a structured light projector, and a second assembly frame B for assembling an RGB camera Three assembly frames C, wherein at least one of the first assembly frame A, the second assembly frame B and the third assembly frame C forms an outward side opening structure.

[0038] The assembly bracket removes part of the outer side wall, so that an outward side opening structure is formed on at least one of the first assembly frame A, the second assembly frame B and the third assembly frame C, and the space it occupies is smaller. Small size reduces the volume of the structured light 3D module, which is conducive to miniaturization and thinning, and the components of the structured light 3D module (structured light camera, structured light projector and RGB camera) that need to be...

Embodiment 2

[0044] Such as Figure 4 As shown, a structured light 3D module includes the assembly bracket 1 described in Embodiment 1, a structured light projector, a structured light camera 21 and an RGB camera 23, and the structured light projector, structured light camera 21 and RGB The camera 23 is respectively fixed in the first assembly frame A, the second assembly frame B and the third assembly frame C by glue.

[0045] The glue is at least one of AA glue, UV glue or thermosetting glue.

Embodiment 3

[0047] Such as Figure 4 and 5 As shown, an assembly method of a structured light 3D module includes:

[0048] Step 1: Provide the assembly bracket 1 described in the first embodiment, the structured light camera 21, the structured light projector 22 and the RGB camera 23;

[0049] Step 2: Fix the structured light camera 21 , the structured light projector 22 and the RGB camera 23 in the first assembly frame A, the second assembly frame B and the third assembly frame C respectively by glue.

[0050] Preferably, in step 2, at least one of the structured light camera 21 , the structured light projector 22 and the RGB camera 23 is assembled into the corresponding assembly frame from the side opening structure of the corresponding assembly frame.

[0051] This step 2 specifically includes:

[0052] Step 2.1: Fix the structured light camera 21 in the first assembly frame A with glue;

[0053] The step 2.1 includes:

[0054] Step 2.1.1: point glue on the inner edge of the first...

Abstract

The invention discloses an assembly bracket for a structured light 3D module. The assembly bracket comprises a first assembly frame for assembling a structured light camera, a second assembly frame for assembling a structured light projector, and a third assembly for assembling an RGB camera, wherein at least one of the first assembly frame, the second assembly frame and the third assembly frame forms an outward side opening structure. The assembly bracket occupies smaller space, is conductive to reducing the size of the structured light 3D module, realizes miniaturization and thinning, and can avoid structural interference of the assembly frames with a device of the structured light 3D module at the side opening structure.

Description

technical field [0001] The invention relates to the field of imaging, in particular to an assembly bracket for a structured light 3D module, a structured light 3D module and an assembly method. Background technique [0002] As Apple uses structured light for face recognition on mobile phones for the first time, the use of structured light for face recognition, 3D sensing and VR equipment will become the mainstream in the future. During the assembly process of the structured light 3D module, it is necessary to fix the structured light camera, the structured light projector and the RGB camera on the same assembly bracket, such as figure 1 As shown, the assembly bracket of the structured light 3D module is a "me"-shaped structure with three assembly frames. This assembly bracket is long and takes up a lot of space, which is not conducive to miniaturization and thinning. The projector and RGB camera can only be assembled from above or below the corresponding assembly frame duri...
