Unless otherwise defined, all terms (including technical and scientific terms) used herein have their ordinary meaning as understood by one of ordinary skill in the art. Furthermore, the definitions of the words and phrases used herein should be understood and interpreted to have a meaning consistent with the context of the present invention. These terms are not to be construed as idealized or overly formal meanings unless expressly so defined.

Please refer to fig. 1-2. Fig. 1 is a schematic perspective view illustrating an optical test machine 100 according to an embodiment of the invention. Fig. 2 is a front view of the optical test machine 100 of fig. 1. In the present embodiment, as shown in fig. 1-2, an optical test apparatus 100 includes a frame 110, a backlight module 120 and an image module 130 (see fig. 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 chassis 112 is spaced apart from the top chassis 111, and the bottom chassis 112 is configured to support the optical device 200. For example, the optical device 200 is an electronic device with a lens. The backlight module 120 is disposed on the top frame 111 and configured to emit light toward the optical device 200. The image module 130 is also disposed on the top frame 111 and between the backlight module 120 and the bottom frame 112. When using the optical test apparatus 100, a user first places the optical device 200 on the chassis 112, and then activates the backlight module 120 to make the backlight module 120 emit light. Light emitted from the backlight module 120 passes through the image module 130 and reaches the lens of the optical device 200, so that a user can test the optical device 200.

Please refer to fig. 3. Fig. 3 is a cross-sectional view of fig. 2 along line A-A. 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 member 131 has a first surface S1, the first surface S1 is far from the top frame 111 and faces the bottom frame 112 (see fig. 1-2 for the top frame 111 and the bottom frame 112), and the first surface S1 is used for disposing a first image film F1 with a pattern. In addition, each of the second image pieces 135 has a second surface S2, and the second surfaces S2 are separated from each other and face the bottom chassis 112 away from the top chassis 111. Further, the second surfaces S2 surround the first surfaces S1 and are separated from the first surfaces S1, and each of the second surfaces S2 is used to provide the 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 with patterns respectively and reaches the optical device 200, so that the optical device 200 can receive the image with patterns through the lens thereof for performing the related test.

Further, in the present embodiment, the second surfaces S2 are arranged symmetrically about the first surface S1. For example, as shown in fig. 3, the number of the second image elements 135 is four, and the four second surfaces S2 are symmetrically distributed in the four corner directions of the first surface S1.

Please refer to fig. 4-5. Fig. 4 is an enlarged view showing the range B of fig. 2. Fig. 5 is a rear exploded view of the second image member 135 of fig. 4. In the present embodiment, as shown in fig. 4-5, each of the second image elements 135 includes a first image plate 136 and a bottom frame 137, and a corresponding one of the second surfaces S2 is located on the first image plate 136. For simplicity of the drawing, the second image film F2 is not shown in fig. 4 to 5. The bottom frame 137 of the second image element 135 is connected between the top frame 111 (see fig. 4 for the top frame 111) of the frame body 110 and the first image plate 136. In an implementation, the first image plates 136 are glass or other plates that can be penetrated by light, but the invention is not limited thereto.

Further, as shown in fig. 4-5, each of the second graphic members 135 also includes a first moving frame 138. The first moving frame 138 is connected between the bottom frame 137 and the first image plate 136, and the first moving frame 138 is configured to move along the first direction D1 relative to the bottom frame 137. That is, the first image plate 136 is movable along the first direction D1 relative to the bottom frame 137 and the frame 110.

More specifically, as shown in fig. 5, the first moving frame 138 includes a frame 1381 and a locking frame 1382. The frame 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 1381, i.e. the locking frame 1382 is rotatable relative to the frame 1381, and the locking frame 1382 is configured to sandwich the first image panel 136 with the frame 1381. More precisely, the locking frame 1382 and the frame 1381 cooperate to clamp at least a portion of the edge of the first image plate 136. To reduce the chance of damage to the first image plate 136, the edges of the first image plate 136 may be coated with a soft material (e.g., foam) for protection. In practice, by rotating the locking frame 1382 relative to the frame 1381, a user may simply and easily fix the first image plate 136 to the first moving frame 138 or remove the first image plate 136 from the first moving frame 138.

Furthermore, since the first moving frame 138 is structurally independent from each other, the user can replace the first image plate 136 fixed between the locking frame 1382 and the frame 1381 together with the second image film F2 disposed thereon one by one, which can effectively reduce the physical burden of the user, and further improve the operation efficiency of the test optical device 200, and further greatly reduce the placing condition of the optical test machine 100 in the factory building, so that the productivity and space can be further improved.

Furthermore, as shown in FIGS. 4-5, each of the second graphic elements 135 also includes a second moving frame 139. The second moving frame 139 is connected between the bottom frame 137 and a frame 1381 of the first moving frame 138, the frame 1381 is configured to move along a first direction D1 relative to the second moving frame 139, and the second moving frame 139 is configured to move along a second direction D2 relative to the bottom frame 137, and 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 plate 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 plate 136 is configured to be provided with the second image film F2, so that the user can move the first image plate 136 along the first direction D1 and/or the second direction D2 relative to the bottom frame 137 and the frame 110, and thus can simply, easily and accurately adjust the position of the second image film F2.

Please refer to fig. 6. Fig. 6 is a cross-sectional view of fig. 4 along line C-C. In the present embodiment, as shown in fig. 6, the first image plate 136 has at least one positioning hole HP, and correspondingly, as shown in fig. 5 to 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 configured to be at least partially inserted into the positioning hole HP of the first image plate 136. In this way, the positioning member 1383 is at least partially inserted into the positioning hole HP, as shown in fig. 6, so that the first image plate 136 can be fixed relative to the locking frame 1382, which is advantageous for fixing the first image plate 136 to the first moving frame 138 or removing the first image plate 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 may be a common locking member, such as a combination of screws and nuts, which will not be described in detail herein.

Please refer to fig. 7. Fig. 7 is a simplified cross-sectional view illustrating a line D-D of fig. 3. In the present embodiment, as shown in fig. 7, the first image member 131 includes a second image plate 132 and a plurality of connection members 133. The first surface S1 is located on the second image plate 132, and the connecting members 133 are respectively connected to the second image plate 132 and a corresponding one of the bottom frames 137. In an implementation, the second image plate 132 is glass or other plate body that can be penetrated by light, but the invention is not limited thereto.

It should be noted 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, i.e. the first surface S1 and the second surface S2 are at the same height level, so that the optical device 200 is beneficial to accurately receive images from the first image film F1 and the second image film F2 for performing related tests.

In summary, the technical solution disclosed in the above embodiment of the present invention has at least the following advantages:

While the present invention has been described with reference to the embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention, and it is intended that the scope of the invention be limited only by the appended claims.
