[0036] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail in combination with the drawings and examples.

[0037] As Figures 2-9 shown, the utility model discloses a kind of film material 80 clean side machine, it includes rack 10, controller, film pressing mechanism, first displacement mechanism, second displacement mechanism, reference alignment mechanism 70, first cleaning assembly 50 and second cleaning assembly 60.Film pressing mechanism includes upper pressing plate 21, lower pressing plate 22 and film pressing driving part 23, lower pressing plate 22 is fixedly arranged in rack 10, upper pressing plate 21 is arranged in the directly above of lower pressing plate 22, and upper pressing plate 21 is slidably connected with rack 10 by linear bearing guide rail, to guarantee the stability of sliding direction, the sliding direction of upper pressing plate 21 is the direction (vertical direction) of approaching or moving away from lower pressing plate 22, and film pressing driving part 23 drives upper pressing plate 21 to move.Film pressing driving part 23 is air cylinder, it is connected with controller.Film pressing mechanism is used to compress the film material 80 (generally speaking, film material 80 is neatly stacked when factory) stacked and placed.Film material 80 is generally quadrilateral structure, it has A side 81, B side 82, C side 83 and D side 84 sequentially adjacent, as Figure 1 shown.Film material 80 is horizontally placed on film pressing mechanism, for positioning placed film material 80, its A side 81 and C side 83 are parallel to X axis, and its B side 82 and D side 84 are parallel to Y axis.

[0038] The first displacement mechanism is used to drive the first cleaning assembly 50 to clean the A side 81 of the film material 80 on the film pressing mechanism. The first displacement mechanism comprises a first horizontal moving module 31 and a first lifting moving module 32. The first horizontal moving module 31 can be a linear moving module based on an electric mechanism (in this case, comprising a motor, a belt assembly and a guide rail assembly). The first lifting moving module 32 can be a linear moving module based on a pneumatic cylinder (in this case, comprising a pneumatic cylinder and a guide rail assembly). Both the first horizontal moving module 31 and the first lifting moving module 32 are connected to a controller. The first horizontal moving module 31 drives the first lifting moving module 32 to move along the X-axis direction, and the first lifting moving module 32 drives the first cleaning assembly 50 to move vertically.

[0039] The second displacement mechanism is used to drive the second cleaning assembly 60 to clean the B side 82, the C side 83 and the D side 84 of the film material 80 on the film pressing mechanism. The sequence can be the B side 82, the C side 83 and the D side 84, or the D side 84, the C side 83 and the B side 82. In this case, the second cleaning assembly 60 is used to clean the B side 82, the C side 83 and the D side 84 in sequence. The second displacement mechanism comprises a second horizontal moving module 41, a third horizontal moving module 42 and a rotating module 43. Both the second horizontal moving module 41 and the third horizontal moving module 42 can be linear moving modules based on an electric mechanism (in this case, comprising a motor, a belt assembly and a guide rail assembly). The rotating module 43 comprises a motor and a turntable. A large gear is arranged on the turntable, and a small gear is arranged on the output shaft of the motor and engaged with the large gear. The second horizontal moving module 41 drives the third horizontal moving module 42 to move along the Y-axis direction, the third horizontal moving module 42 drives the rotating module 43 to move along the X-axis direction, and the rotating module 43 drives the second cleaning assembly 60 to rotate horizontally. Both the second horizontal moving module 41, the third horizontal moving module 42 and the rotating module 43 are connected to a controller.

[0040] The first cleaning assembly 50 and the second cleaning assembly 60 are both the same film material 80 cleaning assembly, which comprises a mounting frame 51, a rotating member 52, a rotating brush 53, a rotating driving member 54, a dust suction cover 56 and a rubber roller 55. The rotating brush 53 and the rubber roller 55 are both located on the same side of the mounting frame 51, and a rubber roller 55 is arranged on each side of the rotating brush 53. The rotating brush 53 and the rubber roller 55 are arranged on a straight line, and the outer diameter of the rotating brush 53 is equal to or slightly larger than the outer diameter of the rubber roller 55, or the rotating brush 53 slightly exceeds or is flush with any tangent line which is tangent to the two rubber rollers 55 at the same time. At this time, the side of the rotating brush 53 which exceeds or is flush with the rubber roller 55 is the cleaning surface. The rotating brush 53 and the rubber roller 55 both correspond to a rotating member 52, and the rotating member 52 is rotationally connected to the mounting frame 51 and is fixed in position relative to the mounting frame 51, that is, the rotating member 52 is limited to only being able to rotate but cannot move in the radial direction and the axial direction. The rotating brush 53 and the corresponding rotating member 52 are detachably connected and synchronously rotate through screws, and the rubber roller 55 and the corresponding rotating member 52 are detachably connected and synchronously rotate through screws. The rotating driving member 54 drives the rotating member 52 corresponding to the rotating brush 53 to rotate. After such arrangement, the rubber roller 55 and the rotating brush 53 can be conveniently disassembled for cleaning or replacement. The rotating driving member 54 can be a motor, which is connected to a controller. The dust suction cover 56 is screwed to the mounting seat, and the rotating brush 53 is arranged in the dust suction cover 56, and part (the cleaning surface) of the rotating brush 53 extends out of the cover opening of the dust suction cover 56. Of course, the rubber roller 55 can also be arranged in the dust suction cover 56, as long as part (the cleaning surface) of the rubber roller 55 extends out of the dust suction cover 56. The dust suction cover 56 is connected to an external suction device through a pipeline, and the external suction device can be a vacuum cleaner. The external suction device can be connected to the controller for control, or the external suction device can be set to be always on.

[0041] When the cleaning surface of the film material 80 cleaning assembly abuts against the side surface of the film material 80, the rotating rotating brush 53 can sweep up burrs, debris and the like attached to the side surface of the film material 80, which are then sucked away. Because the rubber roller 55 can tightly abut against the side surface of the film material 80, and the dust suction cover 56 is arranged, the swept-up debris is not easy to fly out of the film material 80 cleaning assembly, and the debris stubbornly adhered to the side surface of the film material 80 can be removed by the roller pressing of the rubber roller 55, so that secondary pollution is not easy to occur. In addition, because the rubber roller 55 is arranged on each side of the rotating brush 53, it can roll back and forth to ensure the cleaning effect. Finally, it should be noted that the above-mentioned film material 80 cleaning assembly is arranged to clean the side surface of the film material 80 in the present case, and it can also be competent for cleaning the surface of the film material 80 as other application cases.

[0042] In operation, the film material 80 is first positioned on the lower pressing plate 22 in a neat stack, and can be positioned with the A side 81 and any one of the sides adjacent to the A side 81 (the B side 82 or the D side 84) as the reference. After the film material 80 is positioned, the lower pressing plate 22 is pressed to clamp the film material 80. Then, the first displacement mechanism drives the first cleaning assembly 50 to traverse the A side 81 one or more times, and the second displacement mechanism drives the second cleaning assembly 60 to traverse the B side 82, the C side 83 and the D side 84 one or more times.

[0043] The reference alignment mechanism 70 is used to adjust the pose of the film material 80 to ensure accurate positioning of the film material 80. Specifically, the reference alignment mechanism 70 includes a fourth horizontal movement module 71, a fifth horizontal movement module 72, a first positioning plate 73 and a second positioning plate 74. The first positioning plate 73 and the second positioning plate 74 are perpendicular to each other, i.e., the length direction of the first positioning plate 73 is the X-axis direction, and the length direction of the second positioning plate 74 is the Y-axis direction. The fourth horizontal movement module 71 and the fifth horizontal movement module 72 are linear movement modules based on electrical mechanisms or linear modules based on air cylinders, and are both connected to the controller. The fourth horizontal movement module 71 drives the fifth horizontal movement module 72, the first positioning plate 73 and the second positioning plate 74 to move synchronously along the Y-axis direction, and the fifth horizontal movement module 72 drives the second positioning plate 74 to move along the X-axis direction. The alignment method of the reference alignment mechanism 70 can have two modes. In one mode, the first positioning plate 73 cooperates with the fourth horizontal movement module 71 to push the A side 81 of the film material 80 placed on the film pressing mechanism to a set position, and the second positioning plate 74, the fourth horizontal movement module 71 and the fifth horizontal movement module 72 cooperate to push the B side 82 or the D side 84 of the film material 80 placed on the film pressing mechanism to a set position. In the other mode, the first positioning plate 73, the fourth horizontal movement module 71, the first cleaning assembly 50 and the first displacement mechanism cooperate to clamp and position the film material 80 placed on the film pressing mechanism, so that the A side 81 abuts against the first cleaning assembly 50 to achieve positioning of the A side 81. The second positioning plate 74, the fourth horizontal movement module 71, the fifth horizontal movement module 72, the second displacement mechanism and the second cleaning assembly 60 cooperate to clamp and position the film material 80 placed on the film pressing mechanism, so that the B side 82 or the D side 84 abuts against the second cleaning assembly 60 to achieve positioning of the B side 82 or the D side 84.

[0044] To prevent dust from the film material 80 cleaning assembly from being discharged or external dust from being deposited on the bottom of the rack 10 to cause secondary pollution, a water tank 11 for depositing dust is provided at the bottom of the rack 10. In addition, a dust cover 12 is also provided on the outer periphery of the rack 10, and an inlet 13 is provided on the dust cover 12, which is opposite to the film pressing mechanism. A closing door can be selectively provided on the inlet 13 to close the inlet 13.

[0045] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
