Detailed Implementation

[0061] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0062] like Figures 1-3 As shown, a mask inspection fixture includes a fixed base 1, an adjusting base 2, a clamping mechanism 100, and a horizontal adjustment mechanism;

[0063] The clamping mechanism 100 is connected to the adjusting seat 2, and the clamping mechanism 100 is used to clamp and fix the mask 3.

[0064] The adjusting seat 2 is connected to the horizontal adjusting mechanism;

[0065] The horizontal adjustment mechanism is connected to the fixed base 1. This mechanism adjusts the horizontal angle of the adjusting base 2, thereby adjusting the horizontal angle of the mask 3 clamped on the clamping mechanism 100. Specifically, the mask 3 to be tested is first clamped and fixed on the clamping mechanism 100. Then, the horizontal angle of the adjusting base 2 is adjusted by the horizontal adjustment mechanism, simultaneously adjusting the horizontal angle of the mask 3 clamped on the clamping mechanism 100 to ensure the mask 3 is perpendicular to the testing equipment. This helps to ensure the accuracy of the mask 3 testing and the consistency of the testing results.

[0066] likeFigures 1-3 As shown, the horizontal adjustment mechanism may include three lifting mechanisms 200. Each lifting mechanism 200 is connected to the fixed base 1 and the adjusting base 2, and is used to drive corresponding parts on the adjusting base 2 to move up and down to adjust the horizontal angle of the adjusting base 2. Specifically, the three lifting mechanisms 200 can drive three parts on the adjusting base 2 to move up and down respectively. By controlling the height of the three parts on the adjusting base 2, the horizontal angle of the adjusting base 2 can be adjusted, thereby adjusting the horizontal angle of the mask 3 clamped on the clamping mechanism 100, so that the mask 3 meets the horizontal angle requirements of the detection equipment, making the mask 3 perpendicular to the detection equipment. The three lifting mechanisms 200 must not be arranged in a straight line.

[0067] like Figure 2 As shown, the lifting mechanism 200 may include a base 4, a lifting seat 5, a lifting slide 6, a top rod 7, and a lifting drive mechanism;

[0068] The base 4 is connected to the fixed base 1;

[0069] The lifting seat 5 is connected to the adjusting seat 2;

[0070] The lifting slide 6 is slidably connected to the base 4 in the vertical direction;

[0071] The top rod 7 is connected to the lifting slide 6, and the upper end of the top rod 7 abuts against the lifting seat 5 upward;

[0072] The lifting drive mechanism is connected to the lifting slide 6 and drives the lifting slide 6 to move up and down. This, in turn, drives the lifting seat 5 to move up and down via the top rod 7, thereby causing the corresponding part on the adjusting seat 2 to move up and down to adjust the horizontal angle of the adjusting seat 2. Specifically, when the lifting drive mechanism drives the lifting slide 6 to rise, it drives the top rod 7 to rise, which in turn lifts the lifting seat 5, causing the corresponding part on the adjusting seat 2 to rise. When the lifting drive mechanism drives the lifting slide 6 to fall, it drives the top rod 7 to fall, which in turn lowers the lifting seat 5, causing the corresponding part on the adjusting seat 2 to fall. In this embodiment, the lifting slide 6 is slidably connected to the base 4 in the vertical direction via a linear bearing 8.

[0073] like Figure 2 , 3 As shown, the lifting drive mechanism may include a wedge-shaped slider 9, a transmission screw 10, a transmission nut, and a lifting motor 11;

[0074] The wedge-shaped slider 9 is slidably connected to the base 4. The wedge-shaped slider 9 is provided with a driving inclined surface, and the lifting slide 6 is provided with a mating inclined surface that abuts against the driving inclined surface.

[0075] The transmission nut is connected to the wedge-shaped slider 9, and the transmission screw 10 is connected to the transmission nut.

[0076] The lifting motor 11 is connected to the transmission screw 10 and drives the transmission screw 10 to rotate. The transmission screw 10, in conjunction with the transmission nut, drives the wedge-shaped slider 9 to slide, thereby causing the lifting slide block 6 to move up and down through the cooperation of the driving inclined surface and the mating inclined surface. Specifically, the lifting motor 11 can be connected to the base 4 or to the fixed base 1.

[0077] like Figure 1 , 3 As shown, the lifting seat 5 may include an upper connecting part 12, a lower connecting part 13 and a vertical connecting part 14;

[0078] The upper connecting part 12 is connected to the adjusting seat 2;

[0079] The upper end of the vertical connecting part 14 is connected to the upper connecting part 12;

[0080] The lower connecting part 13 is connected to the lower end of the vertical connecting part 14 and is located below the upper connecting part 12;

[0081] The upper connecting part 12 is provided with a downward-facing abutting groove 15;

[0082] The lower connecting part 13 is provided with a through hole 16;

[0083] The upper end of the push rod 7 is provided with a ball head 17, the push rod 7 passes through the through hole 16 and the ball head 17 abuts upward in the abutment groove 15;

[0084] A spring 18 is sleeved on the push rod 7. The upper end of the spring 18 abuts against the ball head 17, and the lower end of the spring 18 abuts against the lower connecting part 13. Specifically, the abutting groove 15 is a V-shaped groove with the opening facing downward. The push rod 7 passes through the through hole 16 to prevent the push rod 7 from slipping off the lifting seat 5. On the one hand, under the action of gravity, the abutting groove 15 in the lifting seat 5 will always remain abutting against the ball head 17 on the push rod 7. On the other hand, the elasticity of the spring 18 can also ensure that the ball head 17 and the abutting groove 15 remain in contact.

[0085] Specifically, the mask detection fixture also includes a controller, and the lifting mechanism 200 also includes a first sensor 19, a second sensor 20, a first sensing plate 21, and a second sensing plate 22;

[0086] The first sensor 21 and the second sensor 22 are respectively connected to the lifting slide 6;

[0087] The first sensor 19 and the second sensor 20 are respectively connected to the base 4 and respectively connected to the controller. The first sensor 19 is used to detect the first sensing element 21 when the lifting slide 6 slides upward to the limit position and send a first signal to the controller. The second sensor 20 is used to detect the second sensing element 22 when the lifting slide 6 slides downward to the limit position and send a second signal to the controller. When the controller receives the first signal or the second signal, it controls the lifting motor 11 to stop operating.

[0088] like Figure 1 , 4 As shown in Figures 5 and 6, the clamping mechanism 100 may include a fixed support member 23, a movable support member 24, and a clamping drive mechanism.

[0089] The fixed support 23 is connected to the adjusting seat 2 and is used to support one end of the mask 3 and to abut against one side wall of the mask 3;

[0090] The movable support 24 is slidably connected to the adjusting seat 2 and is used to support the other end of the mask 3 and abut against the other side wall of the mask 3;

[0091] The clamping drive mechanism is connected to the adjusting seat 2 and is connected to the movable support 24, which is used to drive the movable support 24 toward the fixed support 23 to clamp the mask 3. Specifically, firstly, the movable support 24 is driven to move to a suitable position according to the size of the mask 3 to be clamped. Then, the mask 3 is placed on the fixed support 23 and the movable support 24, so that the fixed support 23 supports one end of the mask 3 and abuts against one side wall of the mask 3, and the movable support 24 supports the other end of the mask 3 and abuts against the other side wall of the mask 3. Then, the clamping drive mechanism drives the movable support 24 toward the fixed support 23 to clamp the mask 3, thereby completing the clamping of the mask 3. More specifically, after the detection is completed, the clamping drive mechanism drives the movable support 24 to move away from the fixed support 23 to release the mask 3.

[0098] The power assembly 300 is connected to the adjusting seat 2 and to the driving wheel 25. The power assembly 300 is used to drive the driving wheel 25 to rotate, thereby driving the transmission belt 27 to move, and then driving the movable support 24 to move towards or away from the fixed support 23 through the connecting block 28. In this embodiment, the driving wheel 25 and the driven wheel 26 are both synchronous pulleys, and the transmission belt 27 is a synchronous belt.

[0103] The tensioning bolt 31 passes through the bolt hole and is threadedly connected to the tensioning seat 30. The tensioning bolt 31 is used to drive the tensioning seat 30 to move, thereby driving the driven wheel 26 to move to tension the transmission belt 27.

[0104] like Figure 1 , 4As shown in Figures 5 and 6, the transmission assembly 400 may be provided in two parts, in which the connecting block 28 of one transmission assembly 400 is connected to one end of the movable support member 24, and the connecting block 28 of the other transmission assembly 400 is connected to the other end of the movable support member 24.

[0108] The clamping motor 34 is connected to the adjusting seat 2 and is connected to the first rotating shaft 35 and the second rotating shaft 36 respectively, and is used to drive the first rotating shaft 35 and the second rotating shaft 36 to rotate respectively, thereby driving the drive wheels 25 in the two transmission components 400 to rotate respectively.

[0109] In this embodiment, a third sensor 37 is connected to the adjusting seat 2, and a third sensing plate 38 is connected to the movable support 24. The third sensor 37 is connected to the controller. The third sensor 37 is used to detect the third sensing plate 38 and send a third signal to the controller when the movable support 24 moves toward the fixed support 23 to its limit position. When the controller receives the third signal, it controls the clamping motor 34 to stop operating.

[0110] The adjusting seat 2 is also connected to a cover 39 that corresponds to and covers the corresponding transmission component 400. The clamping motor 34 and the first rotating shaft 35, as well as the clamping motor 34 and the second rotating shaft 36, are connected by couplings. The clamping motor 34 can be a dual-axis stepper motor. The movable support 24 is slidably connected to the adjusting seat 2 by a linear guide rail.

[0111] like ​ , 4 As shown in Figures 5 and 6, the mask 3 can be a square structure;

[0112] The fixed support member 23 is provided with a first fixed side wall portion 40 and two first fixed material support portions 41, and the movable support member 24 is provided with a first movable side wall portion 42 and two first movable material support portions 43. The two first fixed material support portions 41 are used to support two corners of the first size mask 3, and the two first movable material support portions 43 are used to support the other two corners of the first size mask 3. The first fixed side wall portion 40 is used to abut against one side wall of the first size mask 3, and the first movable side wall portion 42 is used to abut against the other side wall of the first size mask 3.

[0113] The fixed support member 23 is provided with a second fixed side wall portion 44 and two second fixed material support portions 45. The movable support member 24 is provided with a second movable side wall portion 46 and two second movable material support portions 47. The two second fixed material support portions 45 are used to support two corners of the second-sized mask 3, and the two second movable material support portions 47 are used to support the other two corners of the second-sized mask 3. The second fixed side wall portion 44 is used to abut against one side wall of the second-sized mask 3, and the second movable side wall portion 46 is used to abut against the other side wall of the second-sized mask 3.

The third fixed side wall portion 48 is used to abut against one side wall of the third-sized mask 3, and the third movable side wall portion 50 is used to abut against the other side wall of the third-sized mask 3.

[0115] Specifically, the first-sized mask 3 can be 5 inches in size, the second-sized mask 3 can be 6 inches in size, and the third-sized mask 3 can be 7 inches in size. Taking the first-sized mask 3 as an example, the four corners of the first-sized mask 3 are supported by two first fixed support parts 41 and two first movable support parts 43, respectively. By supporting the four corners of the mask 3, the contact area with the mask 3 can be reduced, thus reducing the risk of the mask 3 being contaminated or scratched. When the movable support 24 is driven to move towards the fixed support 23, the first fixed sidewall part 40 and the first movable sidewall part 42 can clamp the mask 3. In this embodiment, three sizes of masks 3 can be clamped and fixed, avoiding frequent changes of fixtures, thereby saving time on fixture changes and improving the efficiency of mask 3 inspection.

[0116] In summary, the mask 3 to be tested is first clamped and fixed on the clamping mechanism 100. Then, the horizontal angle of the adjusting seat 2 is adjusted by the horizontal adjustment mechanism. At the same time, the horizontal angle of the mask 3 clamped on the clamping mechanism 100 can be adjusted so that the mask 3 is perpendicular to the testing equipment, which helps to ensure the accuracy of the mask 3 testing and the consistency of the testing results.
