[0038] The movable bracket 12 is slidably connected with a sliding seat 31, the sliding seat 31 is threadedly connected to the screw rod 13, the sliding seat 31 is rotatably connected with a swing rod 32, the swing rod 32 is fixedly connected with a swing motor 33, the output shaft of the swing motor 33 is fixedly connected with a swing bracket 34, and the sliding seat 31 is fixedly connected with a power mechanism II for driving the swing rod 32 to rotate;

[0039] The swing bracket 34 is fixedly connected to a telescopic mechanism III 41, and the telescopic end of the telescopic mechanism III 41 is fixedly connected to two telescopic mechanisms IV 42, and the telescopic ends of the two telescopic mechanisms IV 42 are fixedly connected to a rotating bracket 43;

[0040] The two rotating brackets 43 are both rotatably connected with a rotating cylinder 51, and the two rotating cylinders 51 are respectively fixedly connected to two grinding mechanisms 52 located on the sides, and the rotating bracket 43 is fixedly connected with a power mechanism III for driving the rotating cylinder 51 to rotate;

[0041] The grinding mechanism 52 includes two grinding rings 521, each of which is fixedly connected to a plurality of grinding teeth 522, the plurality of grinding teeth 522 are mutually staggered, and a telescopic mechanism V 523 is fixedly connected between the two grinding rings 521; the plurality of mutually staggered grinding teeth 522 can make up the distance generated by the movement displacement of the two grinding rings 521, so as to ensure that there is no grinding gap, and achieve comprehensive grinding;

[0042] And during grinding, the telescopic mechanism V523 can be activated to make the multiple grinding teeth 522 and the grinding ring 521 move relative to each other, thereby forming lateral grinding, increasing the grinding track, and thus improving the grinding effect;

[0043] The side mechanism 53 includes a connecting seat 531, and a plurality of telescopic mechanisms VI532 are fixedly connected to the connecting seat 531. A grinding plate 533 is fixedly connected to the telescopic end of each telescopic mechanism VI532. The grinding plate 533 is slidably connected between two adjacent grinding rings 521, and the connecting seat 531 is fixedly connected between two adjacent grinding rings 521.

[0044] When using, Figure 2 As shown, a rigid substrate to be processed is placed on a plurality of clamping brackets 21, and the power mechanism IV is started. The output shaft of the power mechanism IV starts to rotate, and the output shaft of the power mechanism IV drives the gear 25 to rotate. The gear 25 and the rack 14 are meshed for transmission, thereby driving the clamping bracket 21 to slide on the sliding bracket 11, and then adjusting the positions of the plurality of clamping brackets 21 according to the width of the rigid substrate, so that the side of the rigid substrate is located on the outside, thereby facilitating the grinding plate 533 to extend a certain length to grind the side of the rigid substrate; the bottom of the rigid substrate is supported by the plurality of clamping brackets 21, so as to facilitate subsequent grinding;

[0045] Start the telescopic mechanism I 22 and the telescopic mechanism II 23. The telescopic mechanism I 22 and the telescopic mechanism II 23 can be hydraulic cylinders or electric push rods. The telescopic end of the telescopic mechanism I 22 drives the telescopic mechanism II 23 to move, and the telescopic end of the telescopic mechanism II 23 drives the clamping plate 24 to move, thereby adjusting the position of the clamping plate 24 so that the clamping plate 24 can clamp the side of the rigid substrate. By starting the telescopic mechanism I 22 and the telescopic mechanism II 23, the clamping of rigid substrates of different lengths and thicknesses can be completed according to different usage requirements;

[0046] Start the power mechanism I, which is preferably a servo motor. The output shaft of the power mechanism I drives the screw 13 to rotate. When the screw 13 rotates, it drives the sliding seat 31 to move through the thread. The sliding seat 31 drives the swing rod 32 to move. The swing rod 32 drives the swing motor 33 and the swing bracket 34 to move. The swing bracket 34 drives the grinding mechanism 52 and the side mechanism 53 to move, thereby adjusting the positions of the grinding mechanism 52 and the side mechanism 53; so that the grinding mechanism 52 and the side mechanism 53 can move in the length direction of the rigid substrate, thereby fully grinding the rigid substrate;

[0047] Start the power mechanism II, which is preferably a servo motor. The output shaft of the power mechanism II drives the swing rod 32 to swing, and the swing rod 32 drives the swing motor 33 to move. Start the swing motor 33, and the output shaft of the swing motor 33 drives the swing bracket 34 to move, thereby adjusting the angle of the swing bracket 34. Start the telescopic mechanism III41, which is preferably a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism III41 drives the two telescopic mechanisms IV42 to move. The movement of the telescopic ends of the two telescopic mechanisms IV42 can adapt to the deformation of the width of the multiple grinding mechanisms 52 when they are deformed, and can also adjust the positions of the multiple grinding mechanisms 52, and can also adjust the positions of the multiple side mechanisms 53, so that the side mechanisms 53 move to the side of the rigid substrate, so that the rigid substrate can grind the side of the rigid substrates of different widths.

[0048] When it is necessary to adjust the position of the side mechanism 53 according to the width of the rigid substrate, that is, to make the side mechanism 53 located at the side of the rigid substrate and able to contact the side of the rigid substrate, the telescopic mechanism V523 and the telescopic mechanism IV42 are started. The telescopic mechanism V523 and the telescopic mechanism IV42 can be hydraulic cylinders or electric push rods. The telescopic end of the telescopic mechanism IV42 drives the multiple grinding mechanisms 52 and the multiple side mechanisms 53 to move, thereby adjusting the positions of the multiple grinding mechanisms 52 and the multiple side mechanisms 53; the telescopic end of the telescopic mechanism V523 drives the grinding ring 521 to move, adjusts the distance between the two grinding rings 521, and then adjusts the length of each grinding ring 521. In this way, the grinding width can be adjusted according to different usage requirements, and the position of the side mechanism 53 can also be adjusted, so that the side mechanism 53 moves to the side of the rigid substrate;

[0049] The telescopic mechanism VI532 is started. The telescopic mechanism VI532 may be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism VI532 drives the grinding plate 533 to move, and adjusts the extension length of the grinding plate 533. When the side mechanism 53 is located on the upper side of the rigid substrate, the outer side of the grinding plate 533 is flush with the outer side of the grinding ring 521, and the grinding ring 521 acts as the grinding plate 533 to grind the substrate. When the side mechanism 53 is located on the side of the rigid substrate, the grinding plate 533 is extended, and the side of the grinding plate 533 contacts the side of the rigid substrate, and the grinding plate 533 grinds the side of the rigid substrate.

[0050] During grinding, the power mechanism III is started. The power mechanism III is preferably a servo motor. The power mechanism III can be fixedly connected to the rotating bracket 43. The power mechanism III can drive the rotating cylinder 51 to rotate. The output shaft of the power mechanism III starts to rotate. The output shaft of the power mechanism III drives the rotating cylinder 51 to rotate. The rotating cylinder 51 drives the grinding mechanism 52 and the side mechanism 53 to rotate. The multiple grinding mechanisms 52 and the multiple side mechanisms 53 grind the surface of the rigid substrate. The side mechanism 53 grinds the side of the rigid substrate, so that the surface of the rigid substrate reaches the specified roughness and flatness.

[0051] An OLED display screen, wherein the surface of a rigid substrate of the OLED display screen is formed by grinding by a plurality of grinding mechanisms 52 and a plurality of side mechanisms 53, and the side edges of the rigid substrate are formed by grinding by the side mechanisms 53; thus, the rigid substrate is fully ground by the grinding mechanisms 52 capable of adjusting the length and the side mechanisms 53 capable of grinding the side edges, so that the surface of the rigid substrate reaches a specified degree of roughness and flatness;

[0052] Furthermore, during polishing, the telescopic mechanism II 23 is started, and the telescopic end of the telescopic mechanism II 23 drives the clamping plate 24 to move, and the clamping plate 24 drives the rigid substrate to move, so that the rigid substrate slides back and forth left and right, thereby increasing the movement trajectory of the rigid substrate, and can be stretched left and right to ensure the flatness of the rigid substrate;

[0053] Furthermore, when it is necessary to grind some rigid substrates with groove structures, such as Fig.13 As shown, the telescopic mechanism VI532 of the side mechanism 53 on the rigid substrate is started, and the telescopic mechanism VI532 is started. The telescopic end of the telescopic mechanism VI532 drives the polishing plate 533 to move, so that the polishing plate 533 extends, so that the polishing plate 533 can extend into the groove of the rigid substrate to polish the groove of the rigid substrate; and grooves of different depths can be polished according to different usage requirements;

[0054] like Figure 1 As shown, the steps and functions of an OLED display manufacturing process are described in detail below;

[0056] Step 1: Place the rigid substrate on a plurality of clamping brackets 21 for clamping; the plurality of clamping brackets 21 can be used to clamp rigid substrates of different lengths, widths and thicknesses, thereby meeting different processing requirements;

[0057] Step 2: Adjust the positions of the plurality of grinding mechanisms 52 and the plurality of side mechanisms 53 so that the side mechanisms 53 located at the sides of the rigid substrate are expanded; so that the plurality of grinding mechanisms 52 and the plurality of side mechanisms 53 can move to different positions according to different usage requirements to complete the grinding of rigid substrates of different lengths, widths and thicknesses;
