[0003] With the continuous development and innovation of display technology, the requirements for polarizers are becoming higher and higher, especially in terms of dimensional accuracy, shape complexity and production efficiency. Traditional polarizer contour processing fixtures mostly adopt fixed or manually adjustable designs. This design has many limitations in the processing process.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Furthermore, the second support plate 510 is fixedly connected to the bottom left end of another group of guide blocks 3. The top of the second support plate 510 is rotatably connected to a clamping block 51 that cooperates with the clamping rod 54 and the spring 1 53 to clamp the workpiece, and two groups are provided. The left end of the support plate 4 is provided with a limiting assembly that can limit the slide bar 5. The limiting assembly includes a slide bar 5 that provides support and a limiting clamping block 51. Another group of clamping blocks 51 is fixedly connected to the bottom end of the slide bar 5. The slide bar 5 slides through the top of the support plate 4. The right side of the slide bar 5 is provided with a second card slot 56, and multiple groups are provided. The top of the support plate 4 is slidably connected with a shift block 57. By moving the shift block 57, the card block 2 58 can be driven to slide out of the card slot 2 56, and the limit of the slide bar 5 can be released. At this time, the slide bar 5 can be moved to drive the clamping block 51 to move.

[0033] Reference Figure 1 - Figure 2 The left end of the support frame 2 is provided with an adjustment component that can adjust the angle of the clamping component, and the adjustment component includes a clamping block 34. The clamping block 34 slides into the clamping groove 31 to limit the ring 35. The ring 35 is rotatably connected to the left end of the support frame 2. A clamping groove 31 is provided on the right front surface of the ring 35. The clamping block 34 slides on the inner wall of the clamping groove 31. The clamping block 34 cooperates with the torsion spring 32 to slide into the clamping groove 31 to limit the ring 35.

[0034] Reference Figure 1 - Figure 3The top of the clamping block 51 is provided with a circular groove 52 for providing movement of the clamping rod 54, and the inner wall of the circular groove 52 is slidably connected with the clamping rod 54 for supporting the rubber pad 55, and the top of the clamping rod 54 is fixedly connected with the rubber pad 55, and the friction with the workpiece is increased by the rubber pad 55, thereby increasing the stability of clamping, and the clamping rod 54 is elastically connected to the clamping block 51 through the spring 53. When the rubber pad 55 contacts the workpiece, it is squeezed and the spring 53 is squeezed at the same time. The reverse force of the squeezed spring 53 enables the rubber pad 55 to squeeze the workpiece, and the bottom end of another group of clamping blocks 51 at the bottom of the sliding rod 5 is provided with multiple groups of rubber pads 55, clamping rod 54, and spring 53. At the same time, the top end of the clamping block 51 at the top of the support plate 510 is provided with multiple groups of rubber pads 55, clamping rod 54, and spring 53. Through the cooperation of multiple groups of rubber pads 55, clamping rod 54, and spring 53, workpieces of different shapes can be clamped.

[0035] Furthermore, a second clamping block 58 is fixedly connected to the bottom end of the shift block 57, and the second clamping block 58 is elastically connected to the support plate 4 via a second spring 59. The top left side of the second clamping block 58 is set as an inclined surface, and the second clamping block 58 slides on the inner wall of the second slot 56, and is squeezed onto the inclined surface of the second clamping block 58 by the downward movement of the slide bar 5, so that the second clamping block 58 moves to squeeze the second spring 59, and the reverse force of the squeezing of the second spring 59 causes the second clamping block 58 to reset and slide into the second slot 56, so that the slide bar 5 can be limited, so that the slide bar 5 cannot move upward, so that the slide bar 5 cooperates with the clamping block 51 and the rubber pad 55 to always clamp the workpiece.

[0036] Reference Figure 1 - Figure 2 The left front surface of the support frame 2 is rotatably connected with a rotating rod 33 for providing support, and a clamping block 34 is fixedly connected to the left side of the rotating rod 33. The rotating rod 33 and the support frame 2 are elastically connected by a torsion spring 32. One end of the torsion spring 32 is fixedly connected to the outer wall of the rotating rod 33, and the other end of the torsion spring 32 is fixedly connected to the left front surface of the support frame 2. By rotating the clamping block 34, it slides out of the slot 31 and drives the rotating rod 33 to rotate and squeeze the torsion spring 32. At this time, the ring 35 can be rotated to adjust the angle of the clamped workpiece. After the adjustment is completed, the clamping block 34 can be reset and slide into the slot 31 by the reverse force of the torsion spring 32. The ring 35 is limited, thereby realizing flexible control of the angle of the clamped workpiece, so that different surfaces of the workpiece can be processed, improving the processing effect and further enhancing the practicality of the equipment.

[0037] Working principle: When in use, by placing the workpiece on the clamp block 51 and contacting the rubber pad 55 on the clamp rod 54, the slide bar 5 can be pressed downward to squeeze the left top inclined surface of the clamp block 2 58 so that the clamp block 2 58 moves to the right and squeezes the spring 2 59. At the same time, the slide bar 5 drives the other group of clamp blocks 51 to move downward, so that the rubber pad 55 on the other group of clamp blocks 51 contacts the workpiece, and then the slide bar 5 continues to move downward, so that the rubber pad 55 contacts the workpiece and squeezes the workpiece. When the workpiece is irregular, the rubber pad 55 that has not contacted the workpiece continues to move downward and contacts the workpiece. The rubber pad 55 that contacts the workpiece is squeezed and the clamp rod 54 and the spring 1 53 are squeezed at the same time. Through movement, multiple groups of clamp rods 54 and rubber pads 55 can be coordinated to move, so that the spring 1 53 can accurately contact and adapt to the irregular shape of the workpiece. At this time, the reverse force of the squeezing of the spring 2 59 can drive the clamp block 2 58 to reset and slide into the card slot 2 56 to limit the slide bar 5.

[0038] Furthermore, irregular workpieces can be clamped by the cooperation of multiple groups of rubber pads 55, clamping rods 54 and springs 53 on two groups of clamping blocks 51. When multiple groups of clamping blocks 51 are in contact with the workpiece, the clamping rods 54 will move adaptively according to the contour of the workpiece, and cooperate with the springs 53 to ensure that the multiple groups of rubber pads 55 can fit the surface of the workpiece evenly and tightly. Through the coordinated work of multiple groups of clamping rods 54, rubber pads 55 and springs 53, the workpiece can achieve extremely high uniformity when subjected to force, thereby significantly improving the clamping effect.

[0039] By rotating the clamping block 34 to drive the rotating rod 33 to rotate and squeeze the torsion spring 32, the clamping block 34 slides out of the clamping groove 31 to release the limit of the ring 35. At this time, the ring 35 can be rotated to drive the clamping block 51 to rotate, so as to adjust the clamped workpiece. After the adjustment is completed, the reverse force of the torsion spring 32 being squeezed can drive the clamping block 34 to return to the inside of the clamping groove 31, so as to limit the ring 35. Through adjustment, the angle of the clamped workpiece can be flexibly controlled, so that different surfaces of the workpiece can be processed, thereby improving the processing effect and further enhancing the practicality of the equipment.
