The following describes the implementation process of the technical solution of the present invention with reference to specific embodiments, which are not intended to limit the present invention.
The utility model discloses a laser emission module, this laser emission module include laser emission support module and laser emission circuit board.
The laser emission support module includes:
a support body;
a positioning substrate connected with the support body, the positioning substrate having a positioning member;
the laser emission circuit board is arranged on the support body and provided with a locking component, and the locking component and the positioning component are correspondingly arranged to realize the positioning of the laser emission circuit board relative to the positioning substrate.
Fig. 1 and 2 are schematic structural diagrams of the laser emitting support module according to the present invention.
The laser emission support module 100 includes a support body 10, a first positioning substrate 20, and a second positioning substrate 20'. The first positioning substrate 20 and the second positioning substrate 20' are respectively connected to the supporting body 10 and respectively located at two ends of the supporting body 10.
The support body 10 has two faces, fig. 1 shows the structure as seen from the a-face, and fig. 2 shows the structure as seen from the B-face.
The first positioning substrate 20 has a first positioning member 201 and a second positioning member 202, and the second positioning substrate 20' has a third positioning member 203 and a fourth positioning member 204.
The first positioning member 201 and the third positioning member 203 are used to position the first laser emitting circuit board 50.
The second positioning member 202 and the fourth positioning member 204 are used to position the second laser emitting circuit board 60.
Fig. 3 is a schematic structural diagram of a first laser-emitting circuit board 50 according to the present invention.
Fig. 4 is a schematic structural diagram of a second laser-emitting circuit board 60 according to the present invention.
The first laser emitting circuit board 50 has a locking part 501 at one end and a locking part 503 at the other end.
The second laser emitting circuit board 60 has a locking part 502 at one end and a locking part 504 at the other end.
The first laser emitting circuit board 50 shown in fig. 3 may be disposed on the a-side of the supporting body 10, and the first positioning member 201 is inserted into the locking member 501, and the third positioning member 203 is inserted into the locking member 503.
The second laser emitting circuit board 60 shown in fig. 4 may be disposed on the B-side of the support body 10, with the second positioning member 202 embedded in the locking member 502 and the fourth positioning member 204 embedded in the locking member 504.
The first, second, third and fourth positioning parts can be projections, and the corresponding locking parts are grooves.
The first, second, third and fourth positioning parts can be grooves, and the corresponding locking parts are lugs.
As long as the two can be mutually embedded and positioned, the specific form is not limited, and the invention is in the disclosure range.
The first laser emitting circuit board 50, the second laser emitting circuit board 60 and the support body 10 are bonded and fixed to each other to form an independent laser emitting module. The laser emitting module can be further assembled with other modular components to finally form a complete device of the lidar.
The laser emission module needs to further solve the problems of alignment and accurate fixation of the relative position between the first laser emission circuit board 50 and the second laser emission circuit board 60.
Specifically, the present invention realizes the coarse positioning by inserting the first positioning member 201 into the locking member 501, inserting the third positioning member 203 into the locking member 503, inserting the second positioning member 202 into the locking member 502, and inserting the fourth positioning member 204 into the locking member 504. That is, the relative positions of the first laser emitting circuit board 50, the second laser emitting circuit board 60, and the support body 10 are determined.
Further fine positioning is required next.
The first laser emitting circuit board 50 is fitted to the first positioning board 20 and the second positioning board 20' using the a-plane of the support body 10 as a reference plane, and then bonded and fixed. Subsequently, the second laser emitting circuit board 60 can be subjected to fine adjustment.
The second positioning member 202 and the locking member 502 of the second laser emitting circuit board can be fitted to each other with a margin in terms of size design, and are not strictly joined to each other, but have an adjustment gap after fitting. For example, based on fig. 4, the length of the groove of the locking member 502 may be slightly longer than the length (length direction, i.e., y direction) of the second positioning member 202 and the depth of the groove of the locking member 502 may be slightly longer than the depth of the second positioning member 202; and/or, the length of the groove of the locking member 504 may be slightly longer than the length of the fourth positioning member 204 and the depth of the groove of the locking member 504 may be slightly longer than the depth (depth direction, i.e., z direction) of the fourth positioning member 204.
The effect of this adjustment gap is that, since the first laser-emitting circuit board 50 has already been positioned with the laser-emitting support module, the specific set position of the second laser-emitting circuit board 60 is further adjusted based on the set position of the first laser-emitting circuit board 50 at this time. The adjustment may require the use of other tooling or calibration tools. The adjustment gap is left with a margin in space, which facilitates fine adjustment of the second laser emitting circuit board 60 to an accurate position in the first direction and/or the second direction, and then bonding and fixing are performed. The setting of this adjustment clearance can promote the convenience of dress accent, guarantees the accuracy of the inside relative position of laser emission module.
The supporting body 10 has at least one dispensing channel 101. The dispensing channel 101 is used for accommodating the coated adhesive material during adhesion, and prevents the adhesive material from overflowing to affect the electronic devices of the circuit board.
The support body 10 also has a position restricting part 30 for restricting a relative positional relationship between the support body 10 and an adjoining device. The position limiting part 30 can directly support other adjacent devices to realize the fixation of the mutual positions.
As can be seen from fig. 1 and 2, the first positioning members 201 (2) and the second positioning members 202 (1) are different in number, and the third positioning members 203 (1) and the fourth positioning members 204 (2) are different in number.
The first positioning member 201 and the second positioning member 202 extend in different directions, and the first positioning member 201 extends in the x direction and the second positioning member 202 extends in the z direction.
The third positioning member 203 and the fourth positioning member 204 extend in different directions, and the third positioning member 203 extends in the z direction and the fourth positioning member 202 extends in the x direction.
Through the difference of the extending directions, fine adjustment of the same circuit board in two directions can be facilitated, and accurate alignment positions can be obtained finally.
