Description

Adjustable positioning fixture and optical detecting device
The present invention relates to an adjustable positioning fixture and an optical detecting device with an adjustable positioning fixture.
When detecting the display panel, the display panel needs to be positioned below the optical lens to detect whether the screen or appearance of the display panel is defective. In general, there are two ways to position the display panel. One of the positioning methods is to set at least two positioning blocks on the table surface of the detecting machine, and respectively abut the two positioning blocks against the adjacent edges of the display panel. To position the display panel. Another positioning method is to make a positioning fixture with a slot according to the size of the display panel, so that the display panel can be positioned in the slot of the positioning fixture.
However, when the display panel of different sizes needs to be detected, the first positioning mode is caused by the position of the positioning block, which may result in different positions of the center points of the display panels of different sizes, so that the optical lens above the display panel cannot be aligned. The center of the panel may cause errors in detection or cannot be detected. In addition, if the second positioning method is used, it is necessary to manufacture positioning fixtures with different sizes of slots for different size display panels, which cannot be used universally, and the manufacturing cost of the positioning fixture is increased.
One aspect of the present invention is an adjustable positioning fixture.
According to an embodiment of the invention, an adjustable positioning fixture includes a first support member, two slide rails, two second support members, and two first sliders and a third support member. The two slide rails are respectively located at two ends of the first support member. The two second support members are respectively located on two sides of the first support member. Both second supports have a first groove. The two first sliders are slidably coupled to the first grooves, respectively, and coupled to the slide rails respectively to adjust the distance between the second supports by adjusting the position of the first sliders on the slide rails. The third support member is coupled to the second support member, and adjusts a distance between the first support member and the third support member by adjusting a position of the first slider in the first groove.
One aspect of the present invention is an optical detecting device for detecting a display panel.
According to an embodiment of the invention, an optical detection device includes a lens assembly and an adjustable positioning fixture. The adjustable positioning fixture is located below the lens assembly. The adjustable positioning fixture comprises a first support member, two slide rails, two second support members, and two first sliders and a third support member. The two slide rails are respectively located at two ends of the first support member. The two second support members are respectively located on two sides of the first support member. Both second supports have a first groove. The two first sliders are slidably coupled to the first grooves, respectively, and coupled to the slide rails respectively to adjust the distance between the second supports by adjusting the position of the first sliders on the slide rails. The third support member is coupled to the second support member, and adjusts a distance between the first support member and the third support member by adjusting a position of the first slider in the first groove, so that the first support member and the second support member The support member and the third support member surround an area where the display panel is positioned.
In the above embodiment of the present invention, since the two slide rails are respectively located at two ends of the first support member, and the two first sliders are respectively coupled to the two slide rails, the position of the first slider on the slide rail can be adjusted. To adjust the distance between the two second supports. In addition, since the two first sliders are slidably coupled to the two first grooves, respectively, the position between the first support member and the third support member can be adjusted by adjusting the position of the first slider in the first groove. the distance. When different sizes of display panels need to be detected, since the distance between the two second support members is adjustable, and the distance between the first support member and the third support member is also adjustable, the adjustable positioning fixture can be framed.

In this way, the third support member 150 is movable through the second slider 140c along the length direction of the second groove 134a. Since the structures of the second slider 140d and the second groove 152 of the third support member 150 are the same as those of the second slider 140c and the second groove 134a of the second support member 130a, respectively, the description thereof will not be repeated. The second support member 130b can also move through the second slider 140d along the length of the second groove 152.
Figure 6 is a cross-sectional view of the adjustable positioning jig 100 of Figure 1 taken along line 6-6. Referring also to FIGS. 1 and 6, the slide rail 120b may have a recess 121, and the support block 160b may have a convex portion 162. The protrusion 162 of the support block 160b can be coupled to the groove 121 of the slide rail 120b such that the support block 160b can move over the slide rail 120b. Since the structures of the support block 160a and the slide rail 120a on the left side of the first figure are the same as those of the support block 160b and the slide rail 120b on the right side of the first figure, the description thereof will not be repeated.
Fig. 7 is a view showing another embodiment of Fig. 6. The difference from the embodiment of FIG. 6 is that the slide rail 120b has a first groove 122, the support block 160b has a second groove 163, and the ball 124 is located at the first groove of the slide rail 120b. 122 is between the second groove 163 of the support block 160b. With such a design, the support block 160b can still move on the slide rail 120b.
FIG. 8 is a plan view showing the positional display panel 202 of the adjustable positioning jig 100 of FIG. 1 . Referring to FIGS. 1 and 8 , the top of the first support member 110 may have an L-shaped positioning groove 111 , and the tops of the second support members 130 a , 130 b may respectively have an L-shaped positioning groove 131 a (as shown in FIG. 5 ). , 131b (as shown in FIG. 4), the top of the third support member 150 may have an L-shaped positioning groove 151, and the tops of the support blocks 160a, 160b may have L-shaped positioning grooves 161a, 161b, respectively (as shown in FIG. 6 ). The groove bottoms of the L-shaped positioning grooves 111, 131a, 131b, 151, 161a, and 161b are located on the same horizontal plane, and can be used to support and position the display panel 202 to be tested. In addition, the support blocks 160a, 160b can provide the display panel 202 support force to prevent the display panel 202 from rupturing over the slide rails 120a, 120b due to excessive area being suspended.
