[0003] For example, the public document with application number 202021880676.1 discloses a film conveying equipment with a correction device, the utility model includes a first conveying roller and a second conveying roller which are relatively fixed in position, and the film drives the first conveying roller and the second conveying roller to rotate through friction; when the film deviates to one side, the first conveying roller and the second conveying roller rise at the same time, so that only the second conveying roller is separated from the film, so that the film deviation on one side of the first conveying roller and the second conveying roller is restored; then the first conveying roller and the second conveying roller descend at the same time, so that the film deviation on the other side of the first conveying roller and the second conveying roller is restored, the structure is simple, and the correction effect is good. However, the matte film conveying equipment adopts stretching adjustment when correcting the deviated film. During the film conveying process, in order to prevent lengthy sinking, the film is adjusted to a suitable tensioning position limit before conveying.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0022] like Figure 1-Figure 2 As shown, a flexible circuit board matte film conveying equipment includes an assembly frame 1, two assembly frames 1 are symmetrically arranged on the left and right, and conveying rollers 2 are rotatably arranged on the upper and lower ends of the opposite sides of the assembly frame 1, and the surfaces of the conveying rollers 2 are installed with correction mechanisms 3, and support frames 4 are arranged on the outer sides of the surfaces of the assembly frames 1, and movable grooves 41 are opened on the opposite sides of the surfaces of the support frames 4.

[0023] By adopting the above technical solution, the matte film uses friction to drive the conveying roller 2 to rotate during the movement, and the conveying roller 2 limits the upper and lower positions of the matte film; the support frame 4 enables the entire mechanism to be equipped on the equipment.

[0024] Furthermore, the deviation correction mechanism 3 includes fixed plates 301 fixedly installed on the left and right ends of the surface of the conveying roller 2 , and four springs 302 are evenly distributed and fixedly installed around the opposite side of the fixed plate 301 .

[0025] By adopting the above technical solution, the fixing plate 301 enables the entire deflection correcting mechanism 3 to rotate along with the conveying roller 2 , thereby preventing the matte film from being worn when it deviates to the surface of the deflection correcting mechanism 3 .

[0026] Furthermore, the deviation correction mechanism 3 also includes a movable block 303 fixedly installed at one end of the spring 302 away from the fixed plate 301. The movable block 303 is set to a cylindrical cone. The movable block 303 slides closely against the surface of the conveying roller 2. A rubber pad is set on the conical inclined surface of the movable block 303.

[0027] By adopting the above technical solution, the friction of the rubber pad is used to increase the lateral pulling force of the matte film on the surface of the movable block 303, and the deviation rate of the matte film is slowed down; the conical slope is used to move to the surface of the movable block 303 to avoid directly limiting the film at a right angle, which causes wear and wrinkles on the edge of the film; the slidable movable block 303 causes the lateral force of the deviation of the matte film to squeeze the spring 302, so that the spring 302 generates an elastic reaction force, which pushes the movable block 303 to send the matte film back for correction. The correction uses the reaction force generated by the spring 302, which is relatively flexible. During the correction process, the film's own shape and flatness are greatly protected.

[0028] Furthermore, the deviation correction mechanism 3 also includes a connecting rod 304 arranged inside the conveying roller 2. The connecting rod 304 is arranged in a horizontal "I" shape. The upper and lower ends of the vertical rod body of the connecting rod 304 slide through the connecting rod 304 and are fixedly connected to the movable block 303.

[0029] By adopting the above technical solution, the lateral force of the matte film, located on either side, can pull the movable block 303 on the other side through the connecting rod 304, so that the spring 302 on the other side is jointly stressed, and the springs 302 on both sides generate the same direction of restoring elastic force, thereby improving the correction rate.

[0030] like Figure 3-Figure 4 As shown, a guide rod 6 is fixedly installed on the inner surface of the moving groove 41 of the left support frame 4 of the assembly frame 1, and a screw rod 5 is rotatably arranged on the inner surface of the moving groove 41 of the right support frame 4 of the assembly frame 1.

[0031] By adopting the above technical solution, the guide rod 6 can limit the left and right assembly frames 1 formed as a whole by the conveying roller 2 to prevent the left and right assembly frames 1 from forming a whole by the conveying roller 2 and rotating synchronously with the screw rod 5.

[0032] Furthermore, the upper end of the screw rod 5 passes through the support frame 4 and is provided with a driving motor 7 , and the driving motor 7 is fixedly connected to the top end of the outer surface of the right support frame 4 .

[0033] By adopting the above technical solution, the driving motor 7 provides rotational force for the screw rod 5 .

[0034] Furthermore, the guide rod 6 slides through the left assembly frame 1 , and the screw rod 5 is threadedly connected and penetrates the right assembly frame 1 .

[0035] By adopting the above technical solution, the screw rod 5 rotates, the guide rod 6 is limited, and the entire conveying roller 2 is moved up and down by thread pushing to adjust the tension of the matte film during transportation.

[0036] Working principle: When using the flexible circuit board matte film conveying equipment, first, the matte film is manually guided through the middle gap of the conveying roller 2 and wrapped around the winding roller. According to the tensioning requirement of pulling, when the driving motor 7 drives the screw 5 to rotate, the assembly frame 1 can move up and down under the limit of the left guide rod 6 to adjust the position of the conveying roller 2. According to different conveying requirements, the tension of the film can be changed. Then, the rotating motor can be used to make the winding roller pull the matte film for conveying. During the conveying process, when one side of the film deviates, it will use the conical inclined surface to move to the surface of the movable block 303 to avoid directly limiting the film at a right angle, causing wear and wrinkles on the edge of the film, and then use rubber pads to increase friction. The rubbing makes the film's pushing force on the movable block 303 to one side more significant, so that the movable block 303 slides along the conveying roller 2 and squeezes the spring 302. At the same time, the movable block 303 on the other side is pulled to move through the connecting rod 304 and the spring 302 is stretched. The spring 302 on one side generates a thrust after compression, and the spring 302 on the other side generates a restoring force after stretching. The restoring force is transmitted to the movable block 303 on the other side through the connecting rod 304. Under the two unidirectional forces applied by the spring 302, the movable block 303 can push the film back to the middle of the conveying roller 2, so that the film can be stably conveyed in the middle of the conveying roller 2. This is the working principle of the flexible circuit board matte film conveying equipment.
