[0002] At present, rectification systems are often used in the rewinding or unwinding technology of sheets, or in the tape pasting technology of substrates, such as cutting machines, extrusion machines, etc. By rectifying the traveling direction of the sheet or substrate, the purpose of fixed-point rewinding, unwinding or fixed-point tape pasting can be achieved. However, when continuously pasting tapes on a continuously traveling substrate, especially when pasting multiple tapes simultaneously, since the relative positions of the substrate and the tapes need to be coordinated to paste the tapes along a preset trajectory, only rectifying the substrate cannot achieve the desired effect.

[0031] The preferred embodiments in the following description are only for illustration, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description can be applied to other implementation manners, variations, improvements, equivalent manners, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0032] Those skilled in the art should understand that in the disclosure of the specification, the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.

[0033] Combined with the attached drawings of the specification Figures 1 to 3 , on the first aspect, a tape deviation correction system according to a preferred embodiment of the present invention will be elaborated in detail below, wherein the tape deviation correction system includes a substrate monitoring unit 10, a tape monitoring unit 20, and a tape adjustment unit 30.

[0034] The substrate monitoring unit 10, wherein the substrate monitoring unit 10 includes at least one first sensor 11, which is used to monitor the substrate in real time when the substrate is moving, such as the position and width of the substrate. Obviously, in some cases, such as when multiple substrates are conveyed simultaneously, multiple first sensors 11 can also be correspondingly provided, and each first sensor 11 corresponds to monitoring each substrate.

[0035] The tape monitoring unit 20 includes at least one second sensor 21 that communicates with the first sensor 11 to monitor the tape in real time when the substrate is moving, that is, each first sensor 11 monitors one substrate, and each substrate corresponds to one or more second sensors 21, that is, one or more tapes are adhered to the surface of each substrate, and each second sensor 21 corresponds to monitoring one tape.

[0036] For the convenience of introduction, the present application only takes one substrate corresponding to two adhered tapes as an example for illustration. The positions of the tapes (201, 202) are monitored in real time according to the position and width of the substrate monitored by the substrate monitoring unit 10.

[0037] The strip adjusting unit 30 is electrically connected to the strip monitoring unit 20. According to the position and width of the substrate monitored by the substrate monitoring unit 10, the strips (201, 202) can be attached to a predetermined position on the surface of the substrate along a predetermined trajectory. During this process, the position and trajectory of the strips (201, 202) are monitored in real time by the strip monitoring unit 20. When the strips (201, 202) deviate from the predetermined trajectory, the position of the strips (201, 202) is adjusted in a timely manner by the strip adjusting unit 30, so as to perform closed-loop deviation correction adjustment without affecting the strip pasting operation on the substrate, thereby ensuring high working efficiency.

[0038] Specifically, the strip adjusting unit 30 includes at least one deviation correction actuator 31, a pressure member 32 disposed on the deviation correction actuator 31, and at least one supporting roller 33 disposed at the output end of the deviation correction actuator 31. The deviation correction actuator 31 is communicably connected to the second sensor 21. According to the information of the substrate monitored by the first sensor 11, when the second sensor 21 monitors that the pasting trajectory and position of the strips (201, 202) do not meet the requirements, the supporting roller 33 corresponding to the deviation correction actuator 31 is controlled to correct the corresponding strips (201, 202), and the corresponding corrected strips are attached to the surface of the substrate by the pressure member 32. The pressure member 32 includes a pressure roller 321, and the pressure roller 321 can also be implemented as a pressure block. The pressure roller 321 is close to the substrate and maintains a predetermined gap with the substrate to realize the pressure on the strips (201, 202) and attach the strips (201, 202) to the surface of the substrate. The supporting roller 33 is disposed close to the input end of the strips (201, 202) and cooperates with the pressure roller 321, so that the corrected strips (201, 202) can be pressed by the pressure roller 321 onto the surface of the substrate.

[0039] Briefly speaking, under normal circumstances, both the supporting roller 33 and the pressure roller 321 remain stationary, performing strip feeding and pressing respectively. When the position of the strips (201, 202) has a certain deviation, the deviation correction actuator 31 is used to control the left and right movement of the supporting roller 33 to correct the strips (201, 202), so that the corrected strips (201, 202) are pressed by the pressure roller 321 and attached to the surface of the substrate.

[0040] It should be noted that during the process of pressing and attaching, the pressure roller 321 is stationary and will only be moved during material change, maintenance, repair, etc. The movable setting of the pressure roller 321 will be described in detail later.

[0041] As a preferred embodiment of the present invention, the second sensor 21 and the deviation rectifying actuator 31 are correspondingly implemented as two, so as to respectively monitor and adjust the two adhesive strips (201, 202) adhered to the lower surface of the substrate, that is, to simultaneously monitor and adjust two adhesive strips on the surface of the substrate. The two adhesive strips (201, 202) are respectively adhered to both sides of the surface of the substrate, and the two second sensors 21 and the deviation rectifying actuator 31 are correspondingly arranged in sequence along the traveling direction of the substrate, so that the overall structure is more compact and the occupied space of the equipment is reduced.

[0042] As another preferred embodiment of the present invention, the second sensor 21 and the deviation rectifying actuator 31 are correspondingly implemented as four, wherein every two of them are used to respectively monitor and adjust the two adhesive strips adhered to the upper surface of the substrate, and the other two are used to respectively monitor and adjust the two adhesive strips (201, 202) adhered to the lower surface of the substrate, so as to realize the simultaneous monitoring and adjustment of the adhesive application on the upper and lower surfaces of the substrate through the adhesive strip deviation rectifying system, that is, to simultaneously monitor and adjust four adhesive strips on the surface of the substrate, further improving the working efficiency. Preferably, the second sensor 21 and the deviation rectifying actuator 31 for monitoring and adjusting the two adhesive strips (201, 202) on the lower surface of the substrate are arranged at the same station, and the second sensor and the deviation rectifying actuator for monitoring and adjusting the two adhesive strips on the upper surface of the substrate are arranged at another station (not shown in the figure).

[0043] It is worth mentioning that the focus of this application is to realize the on-line adjustment of the positions of the adhesive strips (201, 202) adhered to the surface of the substrate according to the width and position of the substrate during the traveling process of the substrate, and it is not limited to the number of the adhered adhesive strips (201, 202) and is not limited to a specific substrate. The adhesive strip deviation rectifying system can automatically identify the substrate and automatically and continuously adjust the adhering track and adhering position of the adhesive strips (201, 202) based on the substrate, realizing closed-loop control, thereby improving the processing efficiency of the enterprise. The adhesive strips (201, 202) are not limited to being adhered along a straight line.

[0044] In addition, for the specific implementation manner of the movability of the pressure roller 321, the pressure member 32 further includes a telescopic element 322 fixedly arranged on the deviation rectifying actuator 31. The telescopic element 322 is preferably implemented as a cylinder. The pressure roller 321 is connected to the telescopic end of the telescopic element 322 so as to be relatively close to or far away from the substrate, and the distance between the pressure roller 321 and the substrate is controlled by the telescopic movement of the cylinder to realize the pressure application and adhesion of different adhesive strips (201, 202).

[0045] As a preferred embodiment of the present invention, the tape deviation correction system further includes a tape detection unit 40 disposed downstream along the traveling direction of the substrate, where the downstream is with respect to the tape monitoring unit 20 and the tape adjustment unit 30, so as to detect whether the positions of the tapes (201, 202) adhered to the surface of the substrate are qualified after the tapes (201, 202) are adhered, realizing the re-inspection of the tape adhering quality of the substrate and preventing defective products from flowing into the next station or the client. Additionally, to effectively improve the processing quality and save raw materials, the tape detection unit 40 is electrically connected to the tape adjustment unit 30 to timely feedback a signal to the tape adjustment unit 30 for corresponding closed-loop adjustment when the positions of the tapes (201, 202) are unqualified. The tape detection unit 40 is preferably implemented as a linear image acquisition device 41, and the linear image acquisition device 41 is preferably implemented as a line array camera, such as a CCD line array camera, to acquire the surface image information of the substrate. Obviously, those skilled in the art can understand that, to achieve the closed-loop adjustment of the tapes (201, 202), due to a certain distance interval between the linear image acquisition device 41 and the deviation correction actuator 31. Therefore, the unqualified situation detected by the tape detection unit 40 must occur within a certain range where the tapes (201, 202) deviate from the predetermined trajectory, so that the tapes (201, 202) can be corrected by the corresponding deviation correction actuator 31 upstream, otherwise they cannot be adjusted to be qualified.

[0046] Considering that the deviation correction actuator 31 is implemented through a series of electrical components, once these electrical components have problems or there are problems such as no power input, causing the deviation correction actuator 31 to malfunction, then it is necessary to stop the operation of the tape deviation correction system, forcing the enterprise to suspend work. Therefore, as a preferred embodiment of the present invention, the tape adjustment unit 30 further includes a mechanical driving element 34 for driving the deviation correction actuator 31 to move directionally. By mechanically driving the deviation correction actuator 31 to replace the automatic operation of the deviation correction actuator 31, the tape deviation correction system can continue to operate without affecting the processing speed of the enterprise. Specifically, the mechanical driving element 34 includes a lead screw 341, a lead screw nut 342, and a rotating handle 343, where the lead screw nut 342 is rotationally matched with the lead screw 341, and the rotating handle 343 is disposed at any one or both ends of the lead screw 341 for facilitating manual driving of the lead screw 341 to rotate. The deviation correction actuator 31 is movably disposed on the lead screw nut 342 to be able to move directionally along the length direction of the lead screw 341 with the lead screw nut 342 when the lead screw 341 rotates, thereby driving the material supporting roller 33 and the material pressing roller 321 to move together to respectively move and adhere the tapes (201, 202).

[0047] In addition, the tape deviation rectification system further includes a display screen 70, and the display screen 70 is electrically connected to the linear image acquisition device 41.

[0048] In a second aspect, in combination with Figure 4 and Figure 5 , the present invention further provides a cutting machine, and the cutting machine includes a frame 50. The frame 50 has a relative feeding end 51 and a discharging end 52 in the length direction, and at least two rows of mechanical limiting rollers 60 are arranged along the length direction at the feeding end 51 to limit the base material 100 between two adjacent rows of the mechanical limiting rollers 60 so that the base material 100 is fed along a predetermined trajectory. In other words, through two adjacent rows of the mechanical limiting rollers 60, it can be ensured that the base material 100 located between the two rows of mechanical limiting rollers 60 can be directionally conveyed. When a plurality of base materials 100 are conveyed simultaneously, the number of rows of the mechanical limiting rollers 60 is correspondingly increased. For example, when limiting two base materials 100, three rows of the mechanical limiting rollers 60 are required for cooperation, or four rows of the mechanical limiting rollers 60 are required for pairwise cooperation.

[0049] The cutting machine further includes the aforementioned tape sticking and deviation rectification system disposed on the frame 50. The first sensor 11 is disposed at the feeding end 51 of the frame 50 to monitor the position and width of the base material 100. The second sensor 21, the corresponding deviation rectification actuator 31, and the pressing member 32 are disposed between the feeding end 51 and the discharging end 52 of the frame 50 to monitor and adjust the position of the tape (201, 202) relative to the base material 100 so that the tape (201, 202) can be attached to the surface of the base material 100 along a predetermined trajectory.

[0050] To facilitate real-time viewing of the detection situation of the tape detection unit 40 on the tape (201, 202) attached to the surface of the base material 100, as a preferred embodiment of the present invention, the cutting machine further includes a display screen 70 disposed on the frame 50, and the display screen 70 is electrically connected to the linear image acquisition device 41.

[0051] It is worth mentioning that in order to be suitable for conveying base materials 100 with different widths or conveying the base materials 100 from different positions, the gap between two adjacent rows of the mechanical limiting rollers 60 is adjustable.

[0052] In a possible implementation manner, the lead screw 341 is rotatably disposed on the frame 50;

[0053] A limiting guide rail 51 is arranged on the frame 50 along the length direction of the lead screw 341. The deviation rectifying actuator 31 is provided with a slider 311 that cooperates with the limiting guide rail 51, so that when the lead screw 341 rotates, the deviation rectifying actuator 31 can move directionally along the length direction of the lead screw 341 under the limiting action of the limiting guide rail 51.

[0054] It should be noted that in the present invention, the terms "first" and "second" are only used for descriptive purposes, do not represent any order, and cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0055] Those skilled in the art should understand that the embodiments of the present invention described above are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and described in the embodiments. Without departing from the principle, the embodiments of the present invention can have any deformation or modification.
