Please refer to Figures 1 and 2. Figure 1 is a three-dimensional schematic diagram of an optical testing machine 100 according to an embodiment of the present invention. Figure 2 is a front view of the optical testing machine 100 of Figure 1. In this embodiment, as shown in Figures 1 and 2, an optical testing machine 100 includes a frame 110, a backlight module 120, and an image module 130 (see Figure 2 for the backlight module 120 and the image module 130). The frame 110 includes a top frame 111 and a bottom frame 112. The bottom frame 112 is spaced apart from the top frame 111, and the bottom frame 112 is configured to support the optical device 200. For example, the optical device 200 is an electronic device having a lens. The backlight module 120 is disposed on the top frame 111 and is configured to emit light toward the optical device 200. The image module 130 is also disposed on the top frame 111 and is located between the backlight module 120 and the bottom frame 112. When using the optical test machine 100, the user first places the optical device 200 on the bottom frame 112 and then activates the backlight module 120 so that the backlight module 120 emits light. The light emitted from the backlight module 120 passes through the image module 130 and reaches the lens of the optical device 200, so that the user can test the optical device 200.

Please refer to FIG. 3. FIG. 3 is a cross-sectional view along line segment A-A of FIG. 2. In the present embodiment, as shown in FIG. 3, the image module 130 includes a first image element 131 and a plurality of second image elements 135. The first image element 131 has a first surface S1, the first surface S1 is away from the top frame 111 and faces the bottom frame 112 (see FIGS. 1-2 for the top frame 111 and the bottom frame 112), and the first surface S1 is used to set a first image film F1 having a pattern. In addition, each of the second image elements 135 has a second surface S2, the second surfaces S2 are separated from each other and away from the top frame 111 and face the bottom frame 112. Furthermore, the second surface S2 surrounds the first surface S1 and is separated from the first surface S1, and each of the second surfaces S2 is used to set a second image film F2 having a pattern. When the backlight module 120 emits light, the light passes through the first image film F1 and the second image film F2 having patterns and reaches the optical device 200. Therefore, the optical device 200 can receive the image having the pattern through its lens to facilitate related tests.

Furthermore, in this embodiment, the second surfaces S2 are arranged symmetrically with the first surface S1 as the center. For example, as shown in FIG. 3 , there are four second image elements 135 , and the four second surfaces S2 are symmetrically distributed in the four corners of the first surface S1 .

Please refer to FIGS. 4-5. FIG. 4 is an enlarged view of the range B of FIG. 2. FIG. 5 is an exploded view of the rear view of the second image element 135 of FIG. 4. In the present embodiment, as shown in FIGS. 4-5, each of the second image elements 135 includes a first image board 136 and a bottom frame 137, and a corresponding one of the second surface S2 is located on the first image board 136. To make the diagram more concise, the second image film F2 is not shown in FIGS. 4-5. The bottom frame 137 of the second image element 135 is connected between the top frame 111 of the frame 110 (see FIG. 4 for the top frame 111) and the first image board 136. In the implementation application, the first image board 136 is glass or other plates that can allow light to pass through, but the present invention is not limited thereto.

Furthermore, as shown in FIGS. 4-5 , each of the second image elements 135 further includes a first moving frame 138. The first moving frame 138 is connected between the bottom frame 137 and the first image board 136, and the first moving frame 138 is configured to move along the first direction D1 relative to the bottom frame 137. In other words, the first image board 136 can move along the first direction D1 relative to the bottom frame 137 and the frame 110.

More specifically, as shown in FIG. 5 , the first movable frame 138 includes a frame body 1381 and a locking frame 1382. The frame body 1381 is movably connected to the bottom frame 137 along the first direction D1, and the locking frame 1382 is pivotally connected to the frame body 1381, that is, the locking frame 1382 can rotate relative to the frame body 1381, and the locking frame 1382 is configured to clamp the first image board 136 therein with the frame body 1381. More precisely, the locking frame 1382 and the frame body 1381 together clamp at least part of the edge of the first image board 136. In order to reduce the chance of damage to the first image board 136, the edge of the first image board 136 can be covered with a soft material (such as foam) for protection. In fact, by rotating the locking frame 1382 relative to the frame body 1381, the user can simply and easily fix the first image board 136 to the first moving frame 138 or remove the first image board 136 from the first moving frame 138.

Furthermore, since the first movable frames 138 are independent of each other in structure, the user can replace the first image board 136 fixed between the locking frame 1382 and the frame body 1381 together with the second image film F2 disposed thereon one by one, which can effectively reduce the physical burden of the user and thus improve the operating efficiency of the test optical device 200. Moreover, since the operating efficiency of the test optical device 200 is improved, the situation of optical test machines 100 being placed in the factory can be greatly reduced, so that both production capacity and space can be further improved.

Furthermore, as shown in FIGS. 4-5 , each of the second image elements 135 further includes a second moving frame 139. The second moving frame 139 is connected between the bottom frame 137 and the frame body 1381 of the first moving frame 138. The frame body 1381 is configured to move along the first direction D1 relative to the second moving frame 139. The second moving frame 139 is configured to move along the second direction D2 relative to the bottom frame 137. The second direction D2 is perpendicular to the first direction D1. In this way, the first moving frame 138 can move along the first direction D1 relative to the second moving frame 139, and the first image board 136 can move along the first direction D1 and/or the second direction D2 relative to the bottom frame 137 and the frame 110. As described above, the second surface S2 of the first image board 136 is configured to set the second image film F2, so that the user can move the first image board 136 along the first direction D1 and/or the second direction D2 relative to the bottom frame 137 and the frame 110, thereby simply, easily and accurately adjusting the position of the second image film F2.

Please refer to FIG. 6. FIG. 6 is a cross-sectional view along line segment C-C of FIG. 4. In the present embodiment, as shown in FIG. 6, the first image board 136 has at least one positioning hole HP, and correspondingly, as shown in FIGS. 5-6, the first moving frame 138 further includes at least one positioning member 1383. The positioning member 1383 is disposed on the locking frame 1382 and is configured to be at least partially inserted into the positioning hole HP of the first image board 136. In this way, by at least partially inserting the positioning member 1383 into the positioning hole HP, as shown in FIG. 6, the first image board 136 can be fixed relative to the locking frame 1382, which is conducive to fixing the first image board 136 to the first moving frame 138 or removing the first image board 136 from the first moving frame 138.

It should be understood that the connection between the first moving frame 138, the second moving frame 139, the bottom frame 137 and the top frame 111 can adopt common locking devices, such as a combination of screws and nuts, which will not be described in detail here.

Please refer to FIG. 7. FIG. 7 is a simplified cross-sectional view along line segment D-D of FIG. 3. In the present embodiment, as shown in FIG. 7, the first image element 131 includes a second image board 132 and a plurality of connecting members 133. The first surface S1 is located on the second image board 132, and the connecting members 133 are respectively connected to the second image board 132 and the corresponding one of the bottom frame 137. In the implementation application, the second image board 132 is glass or other plates that can be penetrated by light, but the present invention is not limited thereto.

It is worth noting that in the present embodiment, as shown in FIG. 7 , the first surface S1 of the second image plate 132 and the second surface S2 of the first image plate 136 are coplanar with each other, that is, the first surface S1 and the second surface S2 are at the same height level, which is beneficial for the optical device 200 to accurately receive images from the first image film F1 and the second image film F2, so as to facilitate related tests.

In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:

(1) Since the locking frame of the first movable frame is hinged to the frame body, the user can simply and easily fix the first image board to the first movable frame or remove the first image board from the first movable frame by rotating the locking frame relative to the frame body.

(2) Since the first movable frames are structurally independent of each other, the user can replace the first image plate fixed between the locking frame and the frame body together with the second image film disposed thereon one by one, which can effectively reduce the user's physical burden and thus improve the operating efficiency of the test optical device.

(3) Since the first image board can be moved relative to the bottom frame and the frame along the first direction and/or the second direction, and the second surface of the first image board is configured to set the second image film, the user can move the first image board relative to the bottom frame and the frame along the first direction and/or the second direction, thereby simply, easily and accurately adjusting the position of the second image film.

(4) As the operating efficiency of the test optical equipment is improved, the number of optical test machines idle in the factory can be greatly reduced, so that both production capacity and space can be further improved.
