When the luminous circuit board is automatically assembled, the edges of the luminous circuit board are generally clamped by the multidirectional adjusting mechanism so as to adjust the pose of the luminous circuit board. The light-emitting circuit board is limited by strict requirements on the appearance, the size and the weight of the light-emitting circuit board, and the size and the thickness of the light-emitting circuit board are large at present, so that the light-emitting circuit board is easy to bend, deform, collapse and the like in the clamping process.

Further, when the light emitting circuit board is applied to the field of small or micro devices, such as an indicator light, a semiconductor laser, etc., it is difficult to have an excessive space for the adjusting mechanism to clamp the light emitting circuit board due to the limited overall product size, and even if the adjusting mechanism can clamp the edge of the light emitting circuit board, it is difficult to have an excessive space for the adjusting mechanism to move to adjust the pose of the light emitting circuit board for assembly.

Based on the above, in order to ensure the structural stability of the light-emitting circuit board in the adjusting process, and simultaneously in order to facilitate the movement of the adjusting mechanism to adjust the pose of the light-emitting circuit board, the adapter block is fixed on one surface of the light-emitting substrate, and when the light-emitting circuit board is assembled, the adjusting mechanism is matched and butted with the adapter block so as to drive the light-emitting substrate to move to adjust the pose through the adapter block, so that the edge of the light-emitting circuit board cannot be subjected to clamping force in the adjusting and assembling process, bending deformation, edge breakage and other conditions are avoided, and meanwhile, the adjusting mechanism does not occupy the space of the periphery edge of the light-emitting circuit board due to the fact that the adapter block is clamped by the adjusting mechanism, and the pose of the light-emitting circuit board can be adjusted in a narrow space.

The light-emitting circuit board provided by the utility model comprises but is not limited to the fields of illumination, signal indicator lamps, semiconductor lasers and the like.

According to an aspect of an embodiment of the present utility model, referring to fig. 1, a structure of a light emitting circuit board is shown. As shown in the drawing, the light emitting circuit board 100 includes a light emitting substrate 110 and an adapter block 120. The adapter block 120 is fixed on one surface of the light-emitting substrate 110, and is used for being connected with an adjusting mechanism, so that the adjusting mechanism adjusts the light-emitting substrate 110 through the adapter block 120.

Specifically, taking the application of the light-emitting circuit board 100 to a semiconductor laser as an example, during assembly, the pose of the light-emitting circuit board 100 (including, for example, the position, the direction, etc. of the light-emitting circuit board 100) has a high precision requirement, so as to ensure the qualification rate of the assembled product.

The adjusting mechanism can be, for example, a six-way adjusting module or a mechanical arm, and can be connected with the adapter block 120 in a clamping manner during assembly, so that the adapter block 120 can normally drive the light-emitting substrate 110 to move for adjustment under the condition that the peripheral edge space of the light-emitting substrate 110 is limited, and the adjustment assembly of the light-emitting circuit board 100 in a narrow space is realized.

In a specific embodiment, the number of the adapter blocks 120 may be one, and as shown in fig. 1, the adapter blocks 120 may be fixed at a central position of one side of the light-emitting substrate 110, however, in other embodiments, the adapter blocks 120 may be disposed at other positions of one side of the light-emitting substrate 110, and further, when the light-emitting substrate 110 has a larger volume and a heavier mass, in order to ensure that the adjusting mechanism is connected with the adapter blocks 120 to adjust the pose of the light-emitting substrate 110, the plurality of adapter blocks 120 may be disposed symmetrically or in other manners on one side of the light-emitting substrate 110, so as to improve the stability of connection between the adjusting mechanism and the adapter blocks 120, and avoid affecting the accuracy of adjustment due to relative movement between the adjusting mechanism and the adapter blocks 120 during adjustment.

Through setting up the changeover piece 120 in the one side of luminous base plate 110 to make adjustment mechanism adjust luminous base plate 110 through being connected with changeover piece 120, not only can realize normally adjusting luminous circuit board 100's position appearance in narrow and small space, further, because changeover piece 120 is higher for the luminous base plate 110 of thickness weak point, consequently when adjustment mechanism is connected with changeover piece 120 through modes such as centre gripping, changeover piece 120 stable in structure, be difficult for taking place to destroy, thereby for the mode of direct centre gripping luminous circuit board edge, can effectively avoid luminous circuit board 100 to appear bending deformation and collapse scheduling problem.

Regarding the assembly between the adapter block 120 and the light emitting substrate 110, the present utility model proposes an embodiment, specifically, the adapter block 120 is fixed to the light emitting substrate 110 by welding or bonding.

Before designing and producing the light emitting substrate 110, an adhesive or welding area is reserved in advance at a corresponding position on one surface of the light emitting substrate 110, and when the light emitting substrate 110 and the adapter 120 are assembled, the adapter 120 is fixed on the light emitting substrate 110 by means of adhesion or welding, so that the assembly efficiency between the two can be improved.

In order to improve the stability of the assembly connection between the adapter block 120 and the light-emitting substrate 110, the present utility model further proposes an embodiment, specifically, a rough treatment area is disposed on one surface of the light-emitting substrate 110, and the adapter block 120 is fixed on the rough treatment area.

Specifically, the bonding or welding area reserved on one surface of the light-emitting substrate 110 may be treated by sand blasting, chemical etching, grinding, carving, etc. to achieve the effects of improving the surface roughness, decontamination, loosening layer, increasing the surface energy and increasing the surface area of the area, so that the rough treatment area with a larger surface area is more reliably connected with the solder or colloid, and the stable and reliable fixation of the adapter block 120 on the light-emitting substrate 110 is ensured.

By providing the rough treatment area on one surface of the light-emitting substrate 110, it is ensured that after the adapter block 120 is adhered or welded to the rough treatment area, the adapter block 120 is connected with the light-emitting substrate 110 more stably and reliably, so as to provide reliable guarantee for subsequent adjustment.

Referring to fig. 2, a structure of a light emitting circuit board according to another embodiment of the utility model is shown. As shown in the drawings, in some embodiments, the adapter block 120 is constructed in the form of a suction head 121, and one end of the suction head 121 is used to be connected with a suction line to be suction-fixed to the light emitting substrate 110 through the other end.

Specifically, the adsorption pipeline may be a negative pressure pipeline in the production line, and after the adsorption pipeline is connected with the suction head 121, the light-emitting substrate 110 is adsorbed by the suction head, so that the adjusting mechanism can adjust the light-emitting substrate 110 by clamping the suction head 121.

In the embodiment shown in fig. 2, four suction heads 121 are respectively fixed on one surface of the light-emitting substrate 110 near four corners, so as to realize stable and reliable suction of the light-emitting substrate 110. In other embodiments, a corresponding number of the suction heads 121 may be set according to factors such as the volume and the mass of the light emitting substrate 110, for example, when the volume of the light emitting substrate 110 is smaller and the mass is lighter, one suction head 121 may be adsorbed and fixed only at the center or other positions of one surface of the light emitting substrate 110, when the volume and the mass of the light emitting substrate 110 are both moderate, two suction heads 121 distributed symmetrically or in other manners may be adsorbed, and when the volume and the mass of the light emitting substrate 110 are larger and the mass is heavier, three, four or more suction heads 121 may be adsorbed to ensure the stability of adsorption.

By arranging the adapter block 120 as the suction head 121, the suction head 121 can be quickly adsorbed and fixed on the light-emitting substrate 110, so that the efficiency is improved, and the light-emitting substrate 110 can be quickly and efficiently regulated.

In some embodiments, the adapter block 120 is a glass, metal, ceramic, or plastic material.

In some embodiments, the adapter 120 is a cube, cuboid, cylinder, truncated cone, prism, or prismatic table structure.

In the embodiment shown in fig. 1, a square glass block is used as the adapter block 120, and referring to fig. 3, the structure of the side of the embodiment shown in fig. 1 is shown, and as shown in the figure, the adapter block 120 is adhered and fixed on one surface of the light-emitting substrate 110 by the colloid 130, and the colloid is easier to form reliable adhesion with the surface of the light-emitting substrate 110 and the surface of the glass adapter block 120, and the adhesion manner is more convenient and quick, so that the glass adapter block 120 is preferably assembled with the light-emitting substrate 110 by adopting the adhesion manner.

It will be appreciated that the embodiment shown in fig. 1 is only an alternative, and in other embodiments, the adapter 120 may take other shapes, such as a cuboid, a cylinder, a triangular prism, a pentagonal prism, a prismatic table, etc., where the cuboid, the triangular prism, the pentagonal prism, etc. have a plane on the annular side, so that the adjusting mechanism may better clamp the cuboid, the triangular prism, the pentagonal prism, etc.

In order to ensure that the adjusting mechanism can firmly clamp the adapter block 120, the present utility model further provides an embodiment, particularly referring to fig. 4, which illustrates a structure of a light-emitting circuit board according to another embodiment of the present utility model. As shown in the figure, the surface of the adapter block 120 is provided with a roughness structure 122.

Specifically, the surface of the adapter 120 may also be treated by sand blasting, chemical etching, grinding, engraving, etc. to form the roughness structure 122.

As shown in fig. 4, in some embodiments, a rough structure 122 may be disposed on a circumferential surface of the adapter block 120, so that when the adapter block 120 is clamped by the adjusting mechanism, the rough structure 122 contacts with a clamping component of the adjusting mechanism, so as to increase friction force of contact surfaces of the rough structure 122 and the adjusting mechanism, ensure stable and reliable clamping, and further ensure that when the adjusting mechanism adjusts the light-emitting circuit board 100, the light-emitting circuit board 100 does not affect adjustment accuracy due to occurrence of false sliding or the like.

In other embodiments, while the rough structure 122 is disposed on the surface of the annular circumference of the adapter 120, the rough structure 122 may be disposed on the surface of the contact end of the adapter 120 and the light-emitting substrate 110, so as to ensure that the connection strength of the adapter 120 and the light-emitting substrate 110 can be improved when the adapter 120 and the light-emitting substrate are connected and fixed by welding or bonding.

In order to reduce the cost, the utility model also provides an implementation manner, and referring to fig. 5, a structure of a light-emitting circuit board provided by another embodiment of the utility model is shown. As shown in the drawing, the adapter block 120 includes metal studs 123, and the metal studs 123 are attached to the light-emitting substrate 110.

The adapter block 120 adopts the existing metal stud 123, so that no separate design production is required for the adapter block 120, and according to the size of the light-emitting substrate 110, metal studs 123 with different types and specifications can be adopted, so that stability and reliability of an adjusting mechanism when the adjusting mechanism adjusts the light-emitting substrate 110 through the metal studs 123 are ensured.

Specifically, the metal studs 123 may be mounted on the light emitting substrate 110 using a surface mount technology (Surface Mounted Technology, abbreviated as SMT). The SMT process technology is mature, so that the assembly efficiency of the metal stud 123 and the light emitting substrate 110 is improved.

The metal stud 123 is mature in product and low in price, and after the adapter block 120 is arranged as the metal stud 123, the adapter block can be directly purchased in a large batch, so that design production of the adapter block 120 is not needed, the production cost is effectively reduced, meanwhile, the metal stud 123 is assembled on the light-emitting substrate 110 in a mounting mode, the assembly efficiency of the metal stud 123 and the light-emitting substrate can be improved, and the requirement of mass production is met.

In some embodiments, the surface of the metal stud 123 is provided with a knurled structure.

The knurling is a mechanical process for rolling patterns on the pinch grip of a metal product or other working surfaces, and the formed knurling structure mainly plays a role in skid resistance. In this embodiment, the knurling structure is mainly used to improve the clamping stability when the metal stud 123 is clamped by the adjusting mechanism, so as to ensure accurate and reliable adjustment of the light-emitting substrate 110.

According to another aspect of the embodiment of the present utility model, there is also provided a semiconductor laser including the light emitting circuit board 100 in any of the above embodiments.

Because the semiconductor laser structure is small and exquisite, when assembling the luminous circuit board 100, adjustment mechanism needs to adjust luminous circuit board 100 in narrow and small space, to this, through setting up changeover piece 120 in the one side of luminous base plate 110 to make adjustment mechanism adjust luminous base plate 110 through being connected with changeover piece 120, not only can realize normally adjusting luminous circuit board 100's position appearance in narrow and small space, furthermore, because changeover piece 120 is higher for the luminous base plate 110 of thickness is higher, therefore when adjustment mechanism is connected with changeover piece 120 through modes such as centre gripping, changeover piece 120 stable in structure is difficult for taking place to destroy, thereby for the mode of direct centre gripping luminous circuit board, can effectively avoid luminous circuit board 100 to appear bending deformation and edge problem such as burst, and then improve semiconductor laser's yield.
