Alternatively, the support boss may be formed as a separate structure from the decoration 120, for example, the support boss and the decoration 120 may be formed separately and then coupled by welding, glue coupling, or bolting.
In the embodiment of the present disclosure, the glue may be injected into the glue groove 121 by a five-axis dispenser. The five-axis dispenser controls the dispenser to tilt by a predetermined angle, and then injects the connection glue into the glue groove 121. And then placing the decoration 120 after dispensing and dispensing into automatic assembly equipment of the lens 130, centering and assembling the lens 130 and the decoration 120 by the equipment, and performing a curing process after assembling the lens 130 in place.
The bonding glue may be a photosensitive glue, a thermosetting glue, a moisture curing glue, or the like. When the adhesive is a photosensitive adhesive, the lens decoration assembly 10 is cured in a curing light environment after the dispensing and the mounting of the lens 130 are completed. When the connection glue is a thermosetting glue, the lens decoration assembly 10 is heated to be cured after the dispensing and the mounting of the lens 130 are completed. When the connection glue is moisture curing glue, after the dispensing and the mounting of the lens 130 are completed, the lens decoration assembly 10 is put into a pressure maintaining jig for curing.
When dispensing is performed by the five-axis dispenser, it is necessary to ensure that the glue in the glue containing groove 121 is uniform and no air bubbles exist, and at this time, an inclined plane may be disposed in the glue containing groove 121. The top surface of the glue groove 121 may be an inclined surface, and the side surface of the glue groove 121 may be an inclined surface.
As shown in fig. 4, the glue groove 121 has a first wall 21, a second wall 22, and a third wall 23, where the first wall 21 and the third wall 23 are respectively connected to the second wall 22, and the first wall 21 is located at an end of the second wall 22 near the bracket 110, the third wall 23 is located at an end of the second wall 22 far from the bracket 110, the first wall 21 and the second face 132 of the lens 130 are parallel, the distance from the second wall 22 to the axis of the receiving hole in the first direction is gradually increased, the acute angle between the first wall 21 and the second wall 22 is 5 degrees to 12 degrees, the distance from the third wall 23 to the axis of the receiving hole in the first direction is gradually decreased, and the acute angle between the third wall 23 and the first wall 21 is 40 degrees to 50 degrees.
By way of example, the distance from the second wall 22 to the axial center of the receiving hole in the first direction gradually increases, and the acute angle between the first wall 21 and the second wall 22 may be 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, 11 degrees, or the like. The distance from the third wall 23 to the axial center of the accommodating hole in the first direction gradually decreases, and the acute angle between the third wall 23 and the first wall 21 may be 40 degrees, 41 degrees, 44 degrees, 45 degrees, 47 degrees, 50 degrees, or the like.
By setting the acute angle between the first wall 21 and the second wall 22 to 5 degrees to 12 degrees, and setting the acute angle between the third wall 23 and the first wall 21 to 40 degrees to 50 degrees, on the one hand, the uniformity of the connection glue in the glue containing groove 121 is improved, the sealing performance and the reliability of the connection are improved, and on the other hand, the influence on the appearance of the lens decoration 120 due to the existence of bubbles in the connection glue is avoided.
It will be appreciated that in embodiments of the present disclosure, a glue injection hole may be provided in the decoration 120, through which glue is injected into the glue groove 121. At this time, the lens 130 is first mounted to the decoration 120 at the time of assembly such that the lens 130 contacts the support boss, and then the glue is injected into the glue groove 121 through the glue injection hole. Thus, the injection amount of the connection glue can be controlled, and the overflow of the connection glue can be avoided, so that the bottom surface of the lens 130 is polluted.
The glue injection hole may extend from a side of the decoration 120 near the bracket 110 to the glue receiving groove 121, and the glue receiving groove 121 is communicated with the glue injection hole. A plurality of glue injection holes can be formed in the decoration 120, and the glue injection holes are uniformly distributed in the decoration 120. It is understood that the glue injection hole may also extend from the outer side of the decoration 120 or the top of the decoration 120 to the glue groove 121, which is not limited by the embodiment of the disclosure.
When glue is injected through the glue injection holes, the connecting glue can be photosensitive glue, thermosetting glue or moisture curing glue and the like. When the connection glue is a photosensitive glue, after the glue injection and the lens 130 installation are completed, the lens decoration assembly 10 is placed in a curing light environment for curing. When the connection glue is a thermosetting glue, the lens decoration assembly 10 is heated to be cured after the glue injection and the mounting of the lens 130 are completed. When the connection glue is moisture curing glue, after the glue injection and the lens 130 installation are completed, the lens decoration assembly 10 is placed into a pressure maintaining jig for curing.
The lens 130 is disposed in the accommodating hole, and the orthographic projection of the lens 130 on the inner wall of the accommodating hole is at least partially overlapped with the glue accommodating groove 121, so that the connecting glue connects the lens 130 and the decoration 120. The lens 130 is a transparent lens.
The lens 130 has a first surface 131 and a second surface 132 disposed in parallel, the second surface 132 is a surface of the lens 130 near the bracket 110, and a cross-section of the lens 130 parallel to the first surface 131 gradually decreases in area from the first surface 131 to the second surface 132. That is, the side of the lens 130 facing the glue groove 121 is an inclined plane, and the inclined plane can avoid the problem of severe glue overflow caused by scraping the glue during assembly of the lens 130.
For example, the acute angle formed by the third face 133 and the second face 132 of the lens 130 is 70 degrees to 85 degrees, and the third face 133 is a face connecting the first face 131 and the second face 132.
