The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, which are not repeated herein, but the present invention is not limited to the following embodiments.

Fig. 1 and 2 are isometric views of two viewing angles of a turnover panel according to an embodiment of the present invention, respectively, and are intended to show structures provided on a first face and a second face of a turnover panel body. As shown in fig. 1, the turnover board of the present invention includes a board body 1 and a lens holder 2. The board body 1 is a substantially rectangular flat plate, and the lens placement section 2 is located at a substantially central position of the board body 1 and has a substantially rectangular outer contour shape. As can be seen from the perspective of fig. 1, the plate body 1 is provided with a first guide edge 3 on a first side. The first guide ribs 3 are provided at intervals around the lens mount 2 from the outside. The first guide edge 3 is thin-walled, and in order to ensure the minimum space occupied, the shape of the first guide edge is adapted to the shape of the lens holder 2, i.e. the first guide edge is also rectangular. While the number of the first guide edges 3 depends on the overall shape of the lens mount 2, in the present embodiment, the lens mount 2 is rectangular, and therefore the first guide edges 3 are arranged in four and rectangular rows. The gap between adjacent edges is located at the approximate center of each side of the rectangle, so that the guiding function thereof benefits each side of the rectangle formed by the lens mount 2. Alternatively, it is also conceivable that the first guide edge 3 is formed by a full edge which is interrupted in the center of the four sides of the rectangle enclosed by it. According to this concept, if the shape of the lens holder 2 is triangular, circular or other polygonal shape, the number of the first guide edges 3 can be increased or decreased, and the number and form of the first guide edges are adapted to the conventional rectangular lens turret plate. The lens mount 2 is provided on the first surface of the plate body 1 shown in fig. 1 and is configured as a first mount 6. The first resting platform 6 is a rectangular projection projecting with respect to the plate body 1, the height of which projecting with respect to the first face of the plate body 1 is less than the height of the first guide edge 3. The first placing table 6 is provided with the first placing grooves 8 arranged in an array, for example, a rectangular array, so that the maximum number can be set in a limited space to improve the turnover efficiency. The height of the first guide edge 3 relative to the first surface of the plate body 1 is set according to the corresponding lens model, and is specifically higher than the height of the lens placed in the first placing groove 8, so that the lens is prevented from being turned over when the two plates are covered. In addition, two opposite assembling grooves 13 are further formed on two opposite side edges of the plate body 1, and the assembling grooves 13 penetrate through the entire rotating plate along the thickness direction of the plate body 1. In the present embodiment, the two fitting grooves 13 are located right between the adjacent two first guide edges 3 so as to avoid interference with the first guide edges 3. The fitting groove 13 is used for fitting with a positioning pin on an external machine (not shown), and the positioning pin is generally cylindrical, so the fitting groove 13 in this embodiment is semicircular to adapt to the shape of the positioning pin. Of course, the shape of the positioning pin can be changed according to positioning pins with different shapes, such as a triangle or a rectangle.

As shown in fig. 2, in the second surface structure of the turnover plate body 1, a limiting block 5 is arranged on the second surface of the plate body 1. The four limiting blocks 5 are also arranged around the lens placing part 2 from the outside at intervals. In the embodiment shown in fig. 2, the limiting blocks 5 are also rectangular, and the position of each limiting block 5 exactly corresponds to the gap between two adjacent first guiding edges 3 on the first surface of the plate body 1 one by one. The limiting block 5 is a rectangular parallelepiped in this embodiment, and the width thereof is smaller than or equal to the gap between two adjacent first guide edges 3. Since the stopper 5 has a rectangular shape in a plan view when facing upward as shown in fig. 2, the width dimension of the stopper 5 is the long side dimension of the rectangle. If the width dimension is smaller than the gap dimension, the difference between the width dimension and the gap dimension is not too large, otherwise, inaccurate guiding is caused, and the difference range is preferably within 1 mm; if the width dimension is equal to the gap dimension, the limit blocks 5 on the two turnover plates and the first guide edges 3 can form clearance fit in a tolerance setting mode, and the range of the tolerance zone is also within 1 mm. The lens mount 2 is provided on the second surface of the plate body 1 shown in fig. 2 and is configured as a second mount table 7, and the second mount table 7 is provided with a second mount groove 9. In the present embodiment, the second placement grooves 9 are positioned in one-to-one correspondence with the first placement grooves 8 on the first surface of the plate body 1, and are coaxial therewith. As can be seen from fig. 2, the turnover plate of the present invention further includes a second guiding rib 4, and the second guiding rib 4 is located on the second surface of the plate body 1. The second guide ribs 4 are also substantially thin-walled in shape and are also arranged around the lens mount section 2 from the outside. In contrast to the first guide edge, the second guide edge 4 is a continuous edge. In the present embodiment, the second guide rib 4 is arranged along the outer edge of the plate body 1, and has the same shape as the outer shape of the plate body 1, that is, a rectangular shape. Thus, the second guide ridge 4 surrounds both the lens mount 2 and the stopper 5 in the middle, and the stopper 5 is located between the second guide ridge 4 and the lens mount 2. In combination with the above, the assembly grooves 13 extend through the entire revolving plate, so that as shown in fig. 2, the two assembly grooves 13 in this embodiment also extend through two sides of the second guide rib 4 and the two limit blocks 5 at corresponding positions.

For clarity, fig. 3 shows a partial cross-sectional view of a turnaround plate at an edge according to an embodiment of the invention. The structure shown in fig. 3 includes two guide ribs and two placement grooves, and the vertical direction in the drawing is the thickness direction of the plate body 1. In the embodiment shown in fig. 3, the first guide edges 3 and the second guide edges 4 have the same dimensions in the thickness direction of the plate body 1, i.e. the same height relative to the surface of the plate body 1. The outer walls of the first guide ribs 3 are matched to the inner walls of the second guide ribs 4, i.e., the length and width dimensions of the rectangle surrounded by the walls of the two guide ribs correspond to each other in the present embodiment. In this way, after the two peripheral plates are closed with the front and back surfaces facing each other, the first guide rib 3 is inserted inside the second guide rib 4, so that the end surface of the first placing table 6 is engaged with the end surface of the second placing table 7 of the other plate. In the present embodiment, the outer wall of the first guiding edge 3 and the inner wall of the second guiding edge 4 are both inclined surfaces, and the included angle between the inclined surfaces and the plate body 1 is 93-95 degrees. It is also understood that the first and second guide edges are inclined inwardly and outwardly by 3 ° to 5 °, respectively. Design aim at like this, when two turnover boards closure, two inclined planes cooperate each other and play the function of automatic centering to further supplementary first direction arris 3 accomplishes the direction function. Therefore, if the included angle between the inclined plane and the plate body 1 is too small, the auxiliary guide function cannot be realized; too large an angle results in too thin a guide rib, thereby weakening the strength thereof. In order to further ensure the strength of the guide edges, the plate body 1 may be thickened in areas where no adaptation is required. In the embodiment shown in fig. 4, for example, a thickening 14 is provided in the annular region between the first guide rib 3 and the first placement table 6, which increases the strength of the first guide rib 3. The shape of the thickened portion 14 may be adapted to other structures on the first surface of the plate body 1, and the thickening height may be designed according to actual requirements. Therefore, the utility model discloses a mode of direction arris is compared in the mode that uses the locating pin among the prior art, and it is accurate not only to lead, and intensity is higher moreover.

In the embodiment shown in fig. 3, both the first and second placement grooves are tapered grooves, and both extend from the end surfaces of the first and second placement tables toward the plate body 1 to the surface of the plate body 1, respectively, with the tapered tops facing the plate body 1. Because the utility model discloses a turnover board is when using, and the lens cone tip supports usually to accomplish the location on (being on plate body 1) the tank bottom of leaning on the standing groove, thereby the conical surface design of above-mentioned standing groove is in order to avoid cell wall contact lens cone to cause the damage to it. In addition, the lenses at both ends of a general lens protrude outward, and if the shape of the bottom of the flat groove of the placement groove is maintained, the lenses are damaged when the lens is closed. Therefore the utility model provides a tank bottoms of first, two standing grooves of second are equipped with respectively that the first groove 10 of dodging and the second groove 11 of dodging to reserve certain space for the lens at camera lens both ends, avoid its impaired with the contact of turnover plate body 1. In the processing of the lens barrel, a dispensing process is usually included, and baking is performed after dispensing. Glue of usefulness is glued to point this moment can produce gas through toasting, consequently the utility model discloses still set up through-hole 12 on plate body 1 in order to discharge these gases. The first and second coaxial placement grooves may be referred to as a pair of placement grooves, corresponding to one lens. And the utility model discloses at the center of every standing groove and the coaxial through-hole 12 that sets up of the two, through-hole 12 runs through along 1 thickness direction of plate body, and its aperture is 2mm, and this aperture has satisfied the demand of the gas throughput volume of present periscope formula camera lens point gluing toasting in-process just.

The state of the turnover plates in the closing process of the utility model is shown in figure 5, two turnover plates are closed by a mode that the first surface is opposite to the second surface. At the moment, the first guide arris 3 and the limiting block 5 play a role in guiding, so that in the covering process, the first guide arris 3 in the upper turnover plate and the limiting block 5 on the lower turnover plate can be blocked by deflection in any direction, the covering cannot be finished, and the probability of lens damage caused by forced covering due to misalignment of the two turnover plates can be reduced. The second guide edge 4 may further assist in this guiding function. Therefore, as long as the two turnover plates can be covered, the two plates can be confirmed to be in an aligned state, so that the alignment is carried out in a mode of reusing a manual operation auxiliary jig, the labor is saved, and the efficiency is improved.

The above description is only one embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
