[0046] Please refer to Figure 1 。 Figure 1 FIG. 100 is a front schematic view of an optical test station 100 according to an embodiment of the present utility model. In this embodiment, as Figure 1 shown, an optical test station 100 includes a pattern module 110, a fixture 120, a moving module 130, a frame 160, and a backlight module 170. The pattern module 110 and the moving module 130 are respectively connected to the frame 160, and the pattern module 110 and the moving module 130 are separated from each other. The pattern module 110 has at least one pattern thereon. For example, the pattern is attached to the pattern module 110 in the form of a film material. The fixture 120 is configured to clamp and fix the object under test 200. For example, the object under test 200 is an electronic device with an image acquisition function, and the object under test 200 can capture the pattern on the pattern module 110. The backlight module 170 is disposed on the frame 160 and on the side of the pattern module 110 away from the fixture 120. The backlight module 170 is configured to emit light towards the pattern module 110 to enhance the brightness of the pattern on the pattern module 110. The moving module 130 is connected to the fixture 120 and is configured to adjust the relative movement of the fixture 120 with respect to the pattern module 110, so that the object under test 200 is inclined at an angle θ with respect to a specific position P on the pattern module 110 and is separated from the specific position P by a distance L, in order to test the effect of the object under test 200 capturing the pattern. For example, as Figure 1 shown, the specific position P is approximately the central position of the pattern module 110, but the present utility model is not limited thereto.
[0047] By adjusting the angle θ and distance L of the object under test 200 relative to the pattern module 110 through the moving module 130, the orientation of the object under test 200 can easily reach the test conditions, and the test accuracy can be improved. Therefore, the operation efficiency and test quality of the optical test machine 100 can be effectively improved.
[0048] Moreover, since the moving module 130 can adjust the angle θ and distance L of the object under test 200 relative to the specific position P of the pattern module 110, the pattern module 110 can be fixed on the frame 160 without equipping the pattern module 110 with relevant adjustment components to adjust its angle and position. Therefore, the operation efficiency of the optical test machine 100 can be effectively improved.
[0049] Furthermore, as Figure 1 shown, the moving module 130 and the pattern module 110 are arranged along the first direction D1, and the moving module 130 can reciprocally move the fixture 120 relative to the pattern module 110 along the first direction D1 and the second direction D2, where the second direction D2 is perpendicular to the first direction D1. Moreover, the moving module 130 is further configured to rotate the fixture 120 and the object under test 200 relative to the pattern module 110 about the axis X, and the axis X is perpendicular to the first direction D1 and the second direction D2.
[0050] Specifically, as Figure 1 shown, an angle θ is defined between the arrangement direction DA of the fixture 120 relative to the specific position P and the normal direction DN of the pattern module 110, and the normal direction DN of the pattern module 110 is substantially parallel to the first direction D1.
[0051] Furthermore, as Figure 1 shown, the moving module 130 includes a first moving member 131, a pivoting portion 132, and a second moving member 133. The pivoting portion 132 pivotally connects the first moving member 131 about the axis X, and the fixture 120 is connected to the pivoting portion 132. Therefore, the fixture 120 and the object under test 200 can rotate relative to the first moving member 131 about the axis X. More specifically, the pivoting portion 132 is configured to rotate the fixture 120 relative to the first moving member 131 about the axis X so that the object under test 200 can face the specific position P of the pattern module 110. The first moving member 131 is configured to reciprocally move the pivoting portion 132 relative to the pattern module 110 along the first direction D1. The second moving member 133 is connected to the first moving member 131, and the second moving member 133 is configured to reciprocally move the first moving member 131 relative to the pattern module 110 along the second direction D2. In practical applications, for example, the first moving member 131 and the second moving member 133 may respectively include mechanical components such as slide rails, sliders, and motors.
[0052] Moreover, as Figure 1As shown, the optical testing machine 100 further includes an input device 140 and a processing unit 150. The input device 140 is configured to allow a user to input the angle θ and the distance L for testing the object under test 200. The processing unit 150 is signal-connected to the input device 140 and the moving module 130, and is configured to control the moving module 130 according to the angle θ and the distance L input by the user, so as to at least partially synchronously rotate the pivoting portion 132 relative to the first moving member 131 about the axis X, move the pivoting portion 132 of the first moving member 131 relative to the pattern module 110 in the first direction D1, and move the first moving member 131 of the second moving member 133 relative to the pattern module 110 in the second direction D2. In this way, the object under test 200 can reach the specific position P relative to the pattern module 110 at the angle θ and the distance L to be tested more quickly, so the operation efficiency of the optical testing machine 100 can be effectively improved. In practical applications, for example, the input device 140 may have a touch interface to allow the user to input conveniently, and the processing unit 150 may be a programmable logic controller (PLC).
[0053] Please refer to Figure 2 。 Figure 2 For showing Figure 1 the schematic diagram of the range of the angle θ and the distance L of the object under test 200 relative to the specific position P. In practical applications, preferably, the range of the angle θ is between -50 degrees and +50 degrees with respect to the normal direction DN of the specific position P as a reference, and the minimum value Lmin of the distance L is 750 millimeters, and the maximum value Lmax is 1050 millimeters, that is, the range of the distance L is between 750 millimeters and 1050 millimeters. Therefore, as Figure 2 shown, the position range T that the object under test 200 (the object under test 200 is not shown in Figure 2 ) can move relative to the specific position P of the pattern module 110 is approximately fan-shaped.
[0054] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:
[0055] (1) By adjusting the angle and distance of the object under test relative to the specific position of the pattern module through the moving module, the orientation of the object under test can easily reach the test conditions, and the test accuracy can be improved, so the operation efficiency and test quality of the optical testing machine can be effectively improved.
[0056] (2) Since the moving module can adjust the angle and distance of the object under test relative to the specific position of the pattern module, therefore, the pattern module can be fixed on the frame without equipping relevant adjustment components to adjust its angle and position, so the operation efficiency of the optical testing machine can be effectively improved.
[0057] (3) Since the processing unit can control the moving module according to the angles and distances input by the user, thereby at least partially synchronously rotating the pivoting part relative to the first moving member about the axis, moving the pivoting part relative to the pattern module in the first direction along the first moving member, and moving the first moving member relative to the pattern module in the second direction along the second moving member, the object to be tested can reach the specific position relative to the pattern module at the desired test angles and distances more quickly. Therefore, the operation efficiency of the optical testing machine can be effectively improved.
[0058] Although the present invention has been disclosed above in the form of embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the appended claims.
