[0014] The present application is further described below with reference to the accompanying drawings:

[0015] See attached Figure 1-7 A combined wedge mirror gluing jig comprises a base 1, the base 1 is provided with a positioning portion for placing the combined wedge mirror, the positioning portion comprising an oblique section 11 and a lower positioning plane 12 perpendicular to the bottom edge of the oblique section 11; the oblique section 11 is provided with a positioning groove 2; the positioning groove 2 comprises a groove bottom wall 21 parallel to the oblique section 11, a left side wall 22 and a right side wall 23 respectively located on the left and right sides of the groove bottom wall 21, and an upper positioning plane 24 connecting the top ends of the left side wall 22 and the right side wall 23; the upper positioning plane 24 is parallel to the lower positioning plane 12; a notch is provided on the bottom side of the positioning groove 2 opposite to the lower positioning plane 12; the left side wall 22 and the right side wall 23 are arc surfaces with coincident centers; a positioning column 3 is vertically provided on the groove bottom wall 21, and the axis L of the positioning column 3 passes through the centers of the left side wall 22 and the right side wall 23.

[0016] A first glue avoidance groove 4 is horizontally arranged in the middle of the positioning groove 2; the first glue avoidance groove 4 extends radially toward the left side wall 22 and the right side wall 23 along the left and right sides of the positioning column 3 and penetrates the left side wall 22 and the right side wall 23 to divide the positioning groove 2 into the upper positioning groove part 2A and the lower positioning groove part 2B.

[0017] The left and right sides of the positioning column 3 are respectively provided with air-avoiding planes 31 extending along the axial direction thereof.

[0018] The combined wedge mirror gluing jig of the present technical solution limits the side surfaces of the combined wedge mirror by means of the upper positioning plane 24, the lower positioning plane 12, the left side wall 22 and the right side wall 23, and provides a positioning mechanism that cooperates with the circular through hole 30 on the combined wedge mirror by setting the positioning column 3, which can facilitate the completion of the gluing process and the installation of the finished product, and ensure the accuracy of processing and assembly.

[0019] In addition, a first glue avoidance groove 4 is provided at the gluing position of the two wedge-shaped mirror units on the jig, and an avoidance plane 31 is provided on the positioning column 3, which can avoid glue overflowing from the gluing position, preventing the combined wedge-shaped mirror from adhering to the jig and being difficult to remove. Furthermore, the glue avoidance groove can receive dripping glue, thereby reducing glue marks on the combined wedge-shaped mirror and improving the quality of the finished product.

[0020] A second glue avoidance groove 5 is disposed transversely between the bottom side of the positioning groove 2 and the lower positioning plane 12. The notch communicates with the second glue avoidance groove, and the lower end of the lower positioning plane 12 engages with the second glue avoidance groove 5. The provision of the second glue avoidance groove 5 prevents the bottom side of the combined wedge mirror from gluing to the jig.

[0021] The first glue air-avoiding groove 4 and the second glue air-avoiding groove 5 are arranged in parallel; the base 1 has a horizontal bottom surface 13; the first glue air-avoiding groove 4 includes a first groove wall 41 and a second groove wall 42 perpendicular to each other; the first groove wall 41 is parallel to the bottom surface 13 of the base 1; the second glue air-avoiding groove 5 includes a third groove wall 51 and a fourth groove wall 52 and a fifth groove wall 53 perpendicular to the third groove wall 51; the third groove wall 51 is parallel to the bottom surface 13 of the base 1, the fourth groove avoidance is connected with the notch of the positioning groove 2, and the fifth groove wall 53 is connected with the lower positioning plane 12; the angle between the inclined section 11 and the bottom surface 13 is 55 to 65 degrees, and preferably, the angle Q between the inclined section 11 and the bottom surface 13 is 60 degrees. This technical solution sets the positioning groove 2 on the inclined section 11 at a specific angle, which helps to prevent the glue from overflowing into the glue air-avoiding groove when there is excess glue; the glue air-avoiding groove adopts a right-angled groove wall to facilitate the collection of dripping glue.

[0022] Specifically, such as Figure 5-7As shown, the combined wedge mirror includes a left half wedge mirror 10 and a right half wedge mirror 20, each of which includes a flat bottom surface 101, an inclined top surface 102 located above the flat bottom surface 101 and inclined to the flat bottom surface 101, and side surfaces connected between the flat bottom surface 101 and the inclined top surface 102, wherein the side surfaces include a front side surface 103, a right side surface 104, a rear side surface 105 and a left side surface 106 connected end to end, wherein the front side surface 103 and the rear side surface 105 are parallel planes to each other, and the right side surface 104 and the left side surface 106 are arc surfaces with coincident centers.

[0023] In the left semi-wedge-shaped mirror 10, a left semi-circular through hole 107 is provided on the rear side surface 105, extending from the flat bottom surface 101 to the inclined top surface 102, and the axis of the left semi-circular through hole 107 passes through the center of the right side surface 104 and the left side surface 106; in the right semi-wedge-shaped mirror 20, a right semi-circular through hole 108 is provided on the front side surface 103, extending from the flat bottom surface 101 to the inclined top surface 102, and the axis of the right semi-circular through hole 108 passes through the center of the right side surface 104 and the left side surface 106; wherein, the diameter of the left semi-circular through hole 107 is equal to the diameter of the right semi-circular through hole 108, so that the left semi-circular through hole 107 and the right semi-circular through hole 108 form a whole circular through hole 30 when the left semi-wedge-shaped mirror 10 and the right semi-wedge-shaped mirror 20 are glued together.

[0024] When in use, first place the right half-wedge mirror 20 on the lower portion 2B of the positioning groove, with its rear side 105 abutting against the lower positioning plane 12, and the right semicircular through hole 108 fitting into the lower portion of the positioning post 3; then apply glue on the front side 103 of the right half-wedge mirror 20; then place the left half-wedge mirror 10 on the upper portion 2A of the positioning groove, with its rear side 105 gluing into the front side 103 of the right half-wedge mirror 20, and the left semicircular through hole 107 and the right semicircular through hole 108 forming a whole circular through hole 30, and the positioning post 3 passing through the circular through hole 30, as shown in FIG. Figure 3 After the glue dries, take out the combined wedge mirror.
