[0018] Reference Figures 1 to 6 This utility model discloses a film removal device, including: a frame 100, a feeding roller 200, a first film receiving roller 300, a second film receiving roller 400, and a power component 500.

[0019] The feeding roller 200 is rotatably mounted on the frame 100. The feeding roller 200 is used to place materials, which are wound around the feeding roller 200. The feeding roller 200 is used to place rolls of flexible circuit boards. The size of the feeding roller 200 can be adjusted according to the size of the flexible circuit board.

[0020] The first take-up roller 300 is rotatably mounted on the frame 100 and is positioned above the feed roller 200. The first take-up roller 300 is used to receive the dry film on the upper layer of the material. The dry film on the upper layer of the material is wound around the first take-up roller 300. The operator separates the upper dry film of the flexible circuit board from the flexible circuit board and winds it into the first take-up roller 300. The size of the first take-up roller 300 can be adjusted according to the size of the flexible circuit board.

[0021] The second take-up roller 400 is rotatably mounted on the frame 100 and is positioned below the feed roller 200. The second take-up roller 400 is used to receive the dry film of the lower layer of the material. The dry film of the lower layer of the material is wound onto the second take-up roller 400. The operator separates the dry film of the lower layer of the flexible circuit board from the flexible circuit board and winds it into the second take-up roller 400. The size of the second take-up roller 400 can be adjusted according to the size of the flexible circuit board.

[0022] A power component 500 is mounted on the frame 100. The power component 500 drives the feeding roller 200, the first take-up roller 300, and the second take-up roller 400 to rotate. The upper dry film on the flexible circuit board separates from the flexible circuit board and is wound into the first take-up roller 300, while the lower dry film on the flexible circuit board separates from the flexible circuit board and is wound into the second take-up roller 400. This separates the dry film covering the upper and lower sides of the flexible circuit board from the flexible circuit board. This film removal device only requires one operator to initially separate the film and wind the upper dry film into the first take-up roller 300 and the lower dry film into the second take-up roller 400. After starting the device, the power component 500 drives the feeding roller 200, the first take-up roller 300, and the second take-up roller 400 to rotate, separating the upper and lower dry films from the flexible circuit board. The operator then collects the film-removed flexible circuit board.

[0023] In some embodiments, refer to Figures 1 to 6 The device also includes a first rotating shaft 600, a second rotating shaft 700, and a third rotating shaft 800. The first rotating shaft 600, the second rotating shaft 700, and the third rotating shaft 800 are all rotatably mounted on the frame 100. The feeding roller 200 is sleeved on the first rotating shaft 600, the first film taking roller 300 is sleeved on the second rotating shaft 700, and the second film taking roller 400 is sleeved on the third rotating shaft 800. The first rotating shaft 600, the second rotating shaft 700, and the third rotating shaft 800 are used to assist rotation and will not be described in detail.

[0024] In some embodiments, refer to Figures 1 to 6 The first rotating shaft 600, the second rotating shaft 700 and the third rotating shaft 800 are all rotatably mounted on the frame 100 via bearings. The bearings can reduce the friction of the first rotating shaft 600, the second rotating shaft 700 and the third rotating shaft 800 during rotation, making the rotation smoother and reducing energy loss.

[0025] In some embodiments, refer to Figures 2 to 6The power component 500 includes a drive motor 510, a first transmission chain 520a, a second transmission chain 520b, a third transmission chain 520c, a first sprocket 530a, a second sprocket 530b, a third sprocket 530c, a fourth sprocket 530d, a fifth sprocket 530e, and a sixth sprocket 530f. The first sprocket 530a and the second sprocket 530b are both mounted on the output shaft of the drive motor 510. The third sprocket 530c is located at the left end of the first rotating shaft 600, the fourth sprocket 530d is located at the left end of the second rotating shaft 700, and the fifth sprocket 530e and the sixth sprocket 530f are both located at the left end of the third rotating shaft 800. At one end, the first transmission chain 520a is sleeved on the first sprocket 530a and the third sprocket 530c; the second transmission chain 520b is sleeved on the second sprocket 530b and the sixth sprocket 530f; and the third transmission chain 520c is sleeved on the fourth sprocket 530d and the fifth sprocket 530e. The drive motor 510 provides driving force to the first rotating shaft 600, the second rotating shaft 700, and the third rotating shaft 800. The first sprocket 530a and the second sprocket 530b rotate coaxially with the output shaft of the drive motor 510 at the same angular velocity. The first sprocket 530a acts as the driving wheel, driving the third sprocket 530c to rotate via the first transmission chain 520a. Sprocket 530c acts as the driven sprocket, driving the first rotating shaft 600 to rotate; the second sprocket 530b acts as the driving sprocket, driving the sixth sprocket 530f to rotate via the second transmission chain 520b, thereby driving the third rotating shaft 800 to rotate; the fifth sprocket 530e rotates along with the third rotating shaft 800, and as a new driving sprocket, it drives the fourth sprocket 530d to rotate via the third transmission chain 520c, thereby driving the second rotating shaft 700 to rotate. It can be understood that the first sprocket 530a, second sprocket 530b, third sprocket 530c, fourth sprocket 530d, fifth sprocket 530e, and sixth sprocket 530b... The pitch, number of teeth, and tooth profile of wheel 530f are all consistent, which can ensure that all the above chain drives are synchronous drives. Synchronous drives ensure that the rotational angular velocity of the feeding roller 200, the first film receiving roller 300, and the second film receiving roller 400 are consistent, which can realize the synchronous removal of the upper and lower dry film of the flexible circuit board. It is understood that a reducer can be set on the drive motor 510. The reducer can reduce the speed, increase the torque, and increase the stability of the transmission. Compared with belt drive, chain drive has no elastic slippage, can maintain an accurate average transmission ratio, can work well under low speed and heavy load, has high transmission tension, and can be used for heavy object conveying.

[0026] In some embodiments, refer to Figure 1 It also includes a protective box 900, which is located on the outside of the power component 500. The protective box 900 is used to isolate the power component 500 and to protect the operator from accidentally touching the power component 500.

[0027] In some embodiments, refer to Figure 1 The protective box 900 is equipped with a control panel 900a, which is electrically connected to the drive motor 510. The control panel 900a is used to control the start, stop and speed of the drive motor 510, and to control the start and stop of the feeding roller 200, the first film receiving roller 300 and the second film receiving roller 400, as well as the speed of film removal.

[0028] In some embodiments, refer to Figures 1 to 6 The bottom of the rack 100 is provided with several support feet 110. The support feet 110 are used to support the rack 100 and isolate it from the ground. There are generally four support feet 110 to support the rack 100 and keep its bottom away from the ground. This prevents the rack 100 from being placed on the ground for a long time, which would cause corrosion. In addition, the rack 100 is easily scratched during movement. The support feet 110 also make it easier to move the rack 100.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
