In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will appreciate the applicability of other processes and / or the use of other materials.

[0030] Reference below Figures 1-3 A waveguide test fixture 1000 according to an embodiment of the present invention is described. The waveguide test fixture 1000 includes a base 100 and a bracket 200. The base 100 may be shaped approximately like a rectangular parallelepiped or a cube. A groove 110 is provided on the base 100. The groove 110 includes at least one oblique side surface 111. It is understood that the groove 110 may be a V-shaped groove, a U-shaped groove, or similar shape, and the present invention is not limited thereto, as long as the groove 110 includes at least one oblique side surface 111. For example, in an embodiment of the present invention, the groove 110 may be an open groove having only one oblique side surface 111 and a bottom surface 112. Alternatively, the groove 110 may include the oblique side surface 111, the bottom surface 112, and a straight side surface connecting the oblique side surface 111 and the bottom surface 112. It should be noted that the side surface of the groove 110 forms an angle α with the surface of the base 100, where the oblique side surface 111 refers to the side surface formed when 90° < α < 180°.

[0031] Please continue to refer to Figures 1-3 Furthermore, the bracket 200 is disposed on the base 100. The bracket 200 includes at least one supporting surface 201. The waveguide sheet a is disposed between the supporting surface 201 and the oblique side surface 111. The supporting surface 201 and the oblique side surface 111 cooperate to secure the waveguide sheet a. It is understood that the bracket 200 may be disposed on the base 100. The bracket 200 may be disposed on a surface of the base 100 or within a groove 110 of the base 100. This embodiment of the present invention is not limited thereto.

[0032] It should be noted that the bracket 200 can be fixed or movably set on the base 100, and the waveguide plate a is set between the supporting surface 201 of the bracket 200 and the inclined side surface 111 of the groove 110, so that the waveguide a is fixed by the support of the supporting surface 201 and the inclined side surface 111.

[0033] Specifically, for example, in one embodiment of the present invention, alcohol can be evenly sprayed on the supporting surface 201, and then the waveguide plate a to be tested is tilted and placed in the groove 110 of the base 100, and then the waveguide plate a is gently pushed onto the supporting surface 201 sprayed with alcohol. When the supporting surface 201 sprayed with alcohol is bonded to the waveguide plate a, the alcohol will displace the air between the waveguide plate a and the supporting surface 201, so there is no atmospheric pressure in the displaced area. Assuming that the contact area of ​​the displaced air is ΔS and the atmospheric pressure is P, there is an atmospheric pressure difference of f=P*ΔS between the two surfaces of the waveguide plate a. The atmospheric pressure difference is the bonding force of the waveguide plate a on the supporting surface 201, so that the waveguide plate a can be fixed between the supporting surface 201 and the inclined side surface 111, so that the position state of the waveguide plate a is maintained during the detection process without generating internal stress, thereby improving the accuracy of the test results. Moreover, due to the volatility of alcohol, when the waveguide plate a is tested and removed from the waveguide plate test fixture 1000, the alcohol attached to the surface of the waveguide plate a will evaporate quickly, and no residue will be generated on the surface of the waveguide plate a, which is beneficial to improving the yield of the production of the waveguide plate a.

[0034] Of course, in some other embodiments of the present invention, it is also possible to coat a substance with high viscosity such as vaseline on the supporting surface 201, or to stick double-sided tape on the supporting surface 201, so that the waveguide plate a can be attached to the supporting surface 201 through the adhesion of vaseline or double-sided tape.

[0035] The inventors discovered in their research that the placement and stress conditions of the waveguide in the fixture during waveguide processing and testing significantly affect the accuracy of test results. Conventional fixtures often generate internal stresses in the waveguide when holding it. These stresses can cause microstructural deformation in the waveguide, severely impacting the accuracy of test results.

[0036] In view of this, according to the waveguide plate test fixture 1000 of the present invention, a groove 110 is provided on the base 100, and an inclined side surface 111 is provided on the groove 110 for supporting the waveguide plate a. At the same time, a supporting surface 201 is also provided on the base 100, and the waveguide plate a can be attached to the supporting surface 201 using substances such as alcohol, so that the supporting surface 201 and the inclined side surface 111 can act on the waveguide plate a together. On the one hand, the waveguide plate a can maintain its position during the detection process, avoiding the displacement of the waveguide plate a during the test process, affecting the test efficiency and test accuracy, and the waveguide plate a can be vertically set in the waveguide plate test fixture; on the other hand, the waveguide plate a will not generate internal stress during the detection process, thereby further improving the accuracy of the test results of the waveguide plate a.

[0037] Please continue to refer to Figures 1-3In some embodiments, the bracket 200 includes a fixed bracket 210 and a movable bracket 220. The fixed bracket 210 is fixed to the base 100, and the movable bracket 220 can be moved along a first direction (such as Figure 2 The first direction is the arrangement direction of the fixed bracket 210 and the movable bracket 220, and the supporting surface 201 includes a first supporting surface 2011 located on the fixed bracket 210 and a second supporting surface 2012 located on the movable bracket 220. The first supporting surface 2011 and the second supporting surface 2012 are arranged in the same plane, and the first supporting surface 2011, the second supporting surface 2012 and the oblique side surface 111 work together to fix the waveguide sheet a.

[0038] It can be understood that the waveguide plate a is a sheet-like optical element. During the test process, light may need to pass through the waveguide plate a. Therefore, the bracket 200 is set as a fixed bracket 210 and a movable bracket 220. The supporting surface 201 includes a first supporting surface 2011 located on the fixed bracket 210 and a second supporting surface 2012 located on the movable bracket 220. In addition, the first supporting surface 2011 and the second supporting surface 2012 are arranged coplanarly, so that the waveguide plate a can be fixed from opposite ends, so that the central part of the waveguide plate a will not be blocked, and the stability of the waveguide plate a fixed on the waveguide plate test fixture 1000 is guaranteed.

[0039] Furthermore, since the waveguide sheet a has many different models with different shapes or sizes, in the embodiment of the present invention, the bracket 200 is configured as a fixed bracket 210 and a movable bracket 220, and the movable bracket 220 can move along the first direction on the base 100. Therefore, for waveguide sheets a of different shapes or sizes, the waveguide sheet test fixture 1000 can flexibly adjust the position of the movable bracket 220 to adapt to different models of waveguide sheets a, thereby improving the versatility of the waveguide sheet test fixture 1000.

[0040] It should be noted that since the first bearing surface 2011 is disposed on the fixed support 210 and the second bearing surface 2012 is disposed on the movable support 220, when alcohol is sprayed on the first bearing surface 2011 and the second bearing surface 2012 and the waveguide sheet is attached to the first bearing surface 2011 and the second bearing surface 2012, the atmospheric pressure difference between the two surfaces of the waveguide sheet is related to ΔS, where ΔS is the contact area of ​​the displaced air, i.e., the total contact area between the waveguide sheet and the first bearing surface 2011 and the waveguide sheet and the second bearing surface 2012. By adjusting the position of the movable support 220, the magnitude of ΔS can be adjusted, thereby adjusting the adhesion force between the waveguide sheet and the first bearing surface 2011 and the second bearing surface 2012.

[0041] Please continue to refer to Figures 1-3In some optional embodiments, the bracket 200 further includes an adjustment assembly 230. The adjustment assembly 230 is disposed on the base 100, and the movable bracket 220 is disposed on the adjustment assembly 230. The adjustment assembly 230 is used to adjust the position of the movable bracket 220 on the base 100. Thus, by using the adjustment assembly 230 to adjust the movable bracket 220, the adjustment is convenient, which is conducive to improving the testing efficiency of the waveguide sheet a.

[0042] Specifically, the adjustment component 230 can be a component such as a slider, which can move along the first direction on the base 100, thereby driving the movable bracket 220 to move on the base 100. Of course, the adjustment component 230 can also be other structures, and the embodiment of the utility model is not limited to this.

[0043] Please continue to refer to Figures 1-3 In some optional embodiments, the adjustment assembly 230 includes a guide rail 250 and an adjustment unit 240. The guide rail 250 is arranged on the base 100 along a first direction, and the movable bracket 220 is disposed on the guide rail 250. The adjustment unit 240 is connected to the movable bracket 220, and the adjustment unit 240 is adjusted to move the movable bracket 220 along the first direction on the guide rail 250. Thus, by providing the guide rail 250 on the base 100 and arranging the guide rail 250 along the first direction, the movable bracket 220 can move along the guide rail 250 in the first direction, further improving the adjustment stability of the waveguide test fixture 1000 and thereby further improving the accuracy of the waveguide test results.

[0044] It should be noted that the movable bracket 220 is disposed on the guide rail 250 and is connected to the adjustment unit 240, so that by adjusting the adjustment unit 240, the movable bracket 220 can be moved along the first direction on the guide rail 250. The adjustment unit 240 may include a motor, and after the motor is activated, the adjustment unit 240 can adjust the position of the movable bracket 220. Of course, the embodiment of the present invention is not limited to this, and the adjustment unit 240 can also be manually controlled by the tester to adjust the position of the movable bracket 220.

[0045] Please continue to refer to Figures 1-3 In some optional embodiments, the adjustment assembly 230 further includes a guide rail fixing member 260, which is used to fix the guide rail 250 to the base 100. Thus, using the guide rail fixing member 260 to fix the guide rail 250 further improves the stability of the adjustment of the waveguide test fixture 1000, thereby further improving the accuracy of the waveguide test results. The guide rail fixing member 260 can be a fixing element such as a screw or bolt, thereby fixing the guide rail 250 to the base 100.

[0046] Please continue to refer to Figures 1-3In some optional embodiments, the adjusting unit 240 comprises an adjusting screw rod 2403, the movable support 220 is provided with a first threaded hole, the base 100 further comprises a boss 120, the boss 120 is provided with a receiving hole, one end of the adjusting screw rod 2403 extends into the boss 120 through the receiving hole, and the other end of the adjusting screw rod 2403 is connected with the movable support 220 through the first threaded hole and passes through the first threaded hole. When it is necessary to adjust the position of the movable support 220, the movable support 220 can be moved along the first direction on the guide rail 250 by rotating the adjusting screw rod 2403, so that the control of the movable support 220 is simple and easy to operate, which is beneficial to simplify the structure of the waveguide sheet testing fixture 1000 and improve the testing efficiency of the waveguide sheet.

[0047] Understandably, the other end of the adjusting screw rod 2403 is connected with the movable support 220 through the first threaded hole and passes through the first threaded hole, so that the adjusting screw rod 2403 extends out of the side of the movable support 220 away from the guide rail fixing member 260, so as to facilitate the operator to grasp the adjusting screw rod 2403, thereby facilitating the control of the position of the movable support 220.

[0048] It should be noted that the boss 120 can be arranged in the groove 110, and the receiving hole arranged on the boss 120 can be a light hole or a threaded hole, which is not limited in the embodiments of the present application. The base 100 with the groove 110 and the boss 120 can be formed by an integral molding process, so as to simplify the structure of the waveguide sheet testing fixture 1000.

[0049] Please continue to refer to Figures 1-3 In some optional embodiments, the adjusting unit 240 further comprises a screw rod support member 2402, the screw rod support member 2402 is arranged on the base 100, and the screw rod support member 2402 is arranged on the side of the movable support 220 away from the boss 120 to support the adjusting screw rod 2403, the screw rod support member 2402 is provided with a through hole, and the adjusting screw rod 2403 passes through the through hole and extends out of the through hole.

[0050] Please continue to refer to Figures 1-3In some optional embodiments, the adjustment unit 240 further includes a knob 2401, which is disposed on a side of the screw support 2402 away from the movable bracket 220.

When the first supporting surface 2011 and the second supporting surface 2012 are curved surfaces, the first supporting surface 2011 and the second supporting surface 2012 are coplanar, meaning that the surface of the first supporting surface 2011 in contact with the waveguide sheet a is coplanar with the surface of the second supporting surface 2012 in contact with the waveguide sheet a.
