DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0019] The following will be combined Figure 1-Figure 3 A fixing device for producing a double-layer thermal lithographic plate according to an embodiment of the utility model is described in detail.

[0020] Example

[0021] The utility model embodiment provides a fixing device for producing a double-layer thermal lithographic plate, referring to Figure 1 and Figure 3 As shown, it includes a base frame 1, which is installed inside the platemaking machine. Plates that need heat-sensitive processing are placed on the base frame 1. A conveying assembly 13 is arranged on the base frame 1. A screw rod 2 is rotatably connected to the base frame 1. A motor 3 is fixedly connected to the outer wall of the base frame 1. The motor 3 is connected to the screw rod 2 through an output shaft. Moving blocks 4 are threadedly connected on both sides of the screw rod 2. A ventilation pipe 5 is fixedly connected to the moving block 4. A positioning frame 6 is fixedly connected to the middle of the ventilation pipe 5. This structure utilizes the conveying assembly 13 to perform heat-sensitive processing on the plate placed on the base frame 1, and then starts the motor 3 to drive the screw rod 2 to move. The screw rod 2 drives the ventilation pipe 5 on the moving block 4 to move, and then drives the positioning frame 6 to position the plate.

[0022] refer to Figure 1 and Figure 2 As shown, the outer walls on both sides of the screw rod 2 are provided with external threads in opposite directions.

[0023] refer to Figure 3 As shown, guide blocks 10 are fixedly connected to both sides of the bottom of the ventilation pipe 5 , guide rods 11 are slidably connected to the guide blocks 10 , and both ends of the guide rods 11 are fixedly mounted on the base frame 1 .

[0024] refer to Figure 1-Figure 3As shown, a plurality of suction cups 7 are installed on the upper part of the ventilation pipe 5, and one end of the ventilation pipe 5 is connected to the vacuum generator 8 through the air pipe, and the vacuum generator 8 is connected to the compressed air supply pipe. In this structure, when the plate is positioned, a vacuum is generated through the vacuum generator 8, so that the suction cup can suck the plate on the base frame 1, thereby ensuring that the plate will not shift during processing. Compared with the downward pressing fixing method, the entire structure will not block the upper area of ​​the plate, thereby allowing the plate to be fully processed with heat sensitivity.

[0025] refer to Figure 1 and Figure 2 As shown, the conveying assembly 13 includes a bracket 18, a second motor 14 and a plurality of conveying rollers 15. The upper side of the conveying roller 15 protrudes from the top surface of the base frame 1. The conveying roller 15 is rotatably connected to the base frame 1. A rotating wheel 16 is fixedly connected to the same side of the conveying roller 15. A belt 17 is connected between the rotating wheels 16 on two adjacent conveying pipes. The bracket 18 is fixedly mounted on the side wall of the base frame 1. The second motor 14 is fixedly mounted on the bracket 18. The second motor 14 is fixedly connected to one of the conveying rollers 15 through an output shaft. This structure starts the second motor 14 to drive one of the conveying rollers 15 to rotate. The conveying rollers 15 drive other conveying rollers 15 to rotate simultaneously through the rotating wheel 16 and the belt 17, thereby driving the plate material on the conveying roller 15 to move and transport.

[0026] refer to Figure 2 As shown, a plurality of strip-shaped through holes 12 are provided on the top of the base frame 1, and the suction cup 7 moves in the strip-shaped through holes 12. The positioning frame 6 passes through the strip-shaped through holes 12 and is connected to the ventilation pipe 5. The strip-shaped through holes 12 facilitate the movement of the suction cup 7.

[0027] It should be noted that the fixing device composed of the above-mentioned embodiment is applied to the production of double-layer heat-sensitive flat panels.

[0028] The implementation principle of a fixing device for producing a double-layer thermal lithographic plate in an embodiment of the present application is as follows: when in use, start the motor 2 14 to drive one of the conveying rollers 15 to rotate, and the conveying rollers 15 drive the other conveying rollers 15 to rotate simultaneously through the rotating wheel 16 and the belt 17, thereby driving the plate on the conveying roller 15 to move and transport. When the plate is transported to the right place, the motor 3 drives the screw rod 2 to move, and the screw rod 2 drives the vent pipe 5 on the shift block 4 to move, thereby driving the positioning frame 6 to position the plate. At this time, the suction cup 7 is below the plate, and then a vacuum is generated through the vacuum generator 8, so that the suction cup can suck the plate on the base frame 1, thereby ensuring that the plate will not shift during processing.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
