Description

Technical Field

[0001] This utility model belongs to the technical field of die-cutting equipment, specifically relating to a cutting and winding device for polyimide film with high bending resistance. Background Technology

[0002] Although high-bending-strength polyimide films have better bending resistance than ordinary polyimide films, their production processes are actually quite similar, both involving processes such as casting, edge trimming, and slitting.

[0003] As is well known, films produced by casting have irregularly shaped flash on both sides. In order to make the film products appear neat and meet the product size requirements, it is necessary to cut off the flash on both sides of the film to remove the irregular shape.

[0004] During the trimming process of ordinary polyimide films, the removed burrs, once unrestrained, do not remain stiff but accumulate on the bottom of the equipment as the quantity increases, requiring only periodic cleaning. However, due to the inherent structural properties of high-bending-strength polyimide films, the removed burrs are not flexible enough to smoothly fall along the slit to the bottom of the equipment. Instead, they continue to extend diagonally downwards, easily getting stuck in the equipment and causing unnecessary downtime and other equipment malfunctions. To solve this problem, previously, the burrs were continuously and manually trimmed, significantly increasing labor costs. Utility Model Content

[0005] This invention provides a cutting and winding device for polyimide film with high bending resistance, which solves the technical problem that the burrs of polyimide film with high bending resistance need to be continuously manually sorted in order to avoid affecting the normal production of the equipment.

[0006] This utility model includes: a frame;

[0007] Several conveyor rollers are arranged on one side of the frame;

[0008] The finished winding roll is mounted on the frame and is located on one side of the plurality of conveying rolls;

[0009] Two cutting blades are disposed within the frame and correspond to both ends of any one of the conveying rollers;

[0010] Two edge strip rewinders are located at the top of the frame and are respectively above the edge cutting blade;

[0011] Two bare rod cable guides are also located at the top of the frame, and are respectively located on one side of the edge strip rewinder;

[0012] The movable block of the optical rod cable laying device is equipped with a side strip constraint.

[0013] This invention utilizes an edge strip rewinder to recycle and wind the edge strips, and uses a smooth rod wire guide to make the edge strips more evenly distributed during the winding process.

[0014] Further: the edge strip rewinder includes:

[0015] The air shaft is rotatably located inside the frame.

[0016] A drive motor is fixedly mounted on the outside of the frame to drive the air shaft to rotate. The beneficial effect of this step is that the air shaft can quickly fix or release the winding spool used for winding the strip, improving the efficiency of changing the winding spool.

[0017] Furthermore, the frame is also provided with a crossbar, on which a guide ring is fitted. The position of the guide ring corresponds to the cutting blade. The beneficial effect of this step is that it allows the burr strip between the cutting blade and the guide ring to remain parallel to the blade mark, preventing the burr strip from skewing and causing the uncut polyimide film to deviate, thus affecting the cutting quality.

[0018] Furthermore: a commutator is provided on the outside of the bracket of the optical rod cable guide. The commutator is frame-shaped. The beneficial effect of this step is that the feeding direction of the flying edge strip is changed by the commutator, so that it can be smoothly wound onto the edge strip constraint.

[0019] Furthermore, at least one sleeve is provided at a position parallel to the axial direction of the commutator and the guide rod cable assembly. The beneficial effect of this step is that the sleeve reduces the friction between the flash strip and the commutator.

[0020] Furthermore: the edge strip constraint is a roller with at least one groove. The beneficial effect of this step is that the edge strip constraint can provide a certain resistance to the movement of the edge strip, so that the edge strip is in a taut state when it is wound up by the edge strip rewinder, thereby ensuring the flatness of the winding.

[0021] The beneficial effects of this utility model are:

[0022] 1. It can simultaneously rewind the finished film and the cut strips, turning the strips from a disordered state into an ordered state without affecting the normal production of the equipment;

[0023] 2. It can replace manual labor in tidying up the burrs, reducing labor costs. Attached Figure Description

[0032] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0033] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0034] Implementation of this application, for example Figures 1-3 As shown, the edge-cutting and winding device for a high-bending-strength polyimide film provided in this application can simultaneously wind up the cut edge strips 9 during the edge-cutting and winding process of the polyimide film, which can replace manual operation and avoid disorderly extension, thus preventing the equipment from working normally.

[0035] This application includes: rack 1;

[0036] Several conveyor rollers 2 are located on one side of the frame 1. The conveyor rollers 2 are generally rotatably connected to the frame 1 at both ends through bearings. Several conveyor rollers 2 can tighten the polyimide film that is fed in, which is more conducive to subsequent slitting.

[0037] The finished product take-up roller 3 is mounted on the frame 1 and is located on one side of several conveying rollers 2. The finished product take-up roller 3 is used to take up the neat finished film 8 after removing the burrs 9.

[0038] Two cutting blades 4 are located inside the frame 1 and correspond to the two ends of any one of the conveying rollers 2. The corresponding position of the cutting blades 4 is generally selected to be the conveying roller 2 located in the middle of the multiple conveying rollers 2, which is more conducive to ensuring the cutting effect.

[0039] Two edge strip rewinders 5 are located at the top of the frame 1 and above the cutting blade 4, respectively, and can also rewind the edge strip 9.

[0040] Two bare rod cable guides 6 are also located at the top of the frame 1, and are respectively located on one side of the edge strip rewinder 5;

[0041] The moving block of the bare rod cable guide 6 is provided with an edge strip constraint 61. The edge strip constraint 61 can prevent the flying edge strip 9 from losing control and can also provide a little constraint force on the flying edge strip, so that the flying edge strip 9 can be reciprocated with the bare rod cable guide 6 under force, so that the edge strip rewinder 5 can be wound more smoothly.

[0042] Specifically, such as Figure 1 As shown in the figure, the direction of the arrow indicates the feeding direction of the polyimide film. The polyimide film is cut by the edge cutting knife 4 after passing through the conveyor roller 2. The finished film 8 is wound up by the finished film winding roller 3. At the same time, the generated burrs 9 are evenly wound up by the edge winding device 5 under the guidance of the smooth rod wire guide 6. This can avoid the unrestrained burrs 9 from causing equipment production failures and can also save labor costs.

[0043] Based on the above technical solution, the edge strip rewinder 5 includes:

[0044] An air shaft is rotatably located inside the frame 1. The air shaft is a shaft whose surface can protrude after being inflated by high pressure and whose surface part quickly retracts after being deflated. The air shaft can quickly fix or release the winding spool used for winding the strip 9, providing efficiency for changing the winding spool.

[0045] The drive motor is fixedly located on the outside of the frame 1 and is used to drive the air shaft to rotate. The drive motor and the air shaft are generally connected by a coupling or similar component. In order to improve the winding effect and winding reliability, for example, a servo motor and related sensors can be used to control the speed of the servo motor by detecting the winding tension of the burr strip 9.

[0046] Based on the above technical solution, the frame 1 is further provided with a crossbar, on which a guide ring 7 is fitted. The position of the guide ring 7 corresponds to the cutting blade 4, ensuring that the burr strip 9 between the cutting blade 4 and the guide ring 7 remains parallel to the blade mark, preventing the burr strip 9 from skewing and causing the uncut polyimide film to deviate, thus affecting the cutting quality. Figure 2 As shown, the guide ring 7 includes a sleeve 71 and a ring 72. The sleeve 71 is fitted onto the crossbar. A threaded hole can be opened in the sleeve 71, and the position of the sleeve 71 on the crossbar can be fixed by a set screw. In this way, the position of the sleeve 71 on the crossbar is adjustable, and it can have the same position adjustment capability as the edge cutting tool 4, which can be used for polyimide films of different widths. Secondly, the flash strip 9 passes through the ring 72. The ring 72 can restrict the flash strip 9 within a small range and will not bring great resistance to the flash strip 9.

[0047] Based on the above technical solution, a commutator 62 is provided on the outside of the bracket of the optical rod cable 6. The commutator 62 is frame-shaped, and the sprue 9 passes through the commutator 62. The commutator 62 changes the feeding direction of the sprue 9 so that it can smoothly wrap around the sprue constraint 61.

[0048] Based on the above technical solution, at least one sleeve 621 is provided at a position parallel to the axis of the commutator 62 and the optical rod cable 6, and the sleeve 621 is used to reduce the friction between the flash strip 9 and the commutator 62.

[0049] Based on the above technical solution, the edge strip constraint 61 is a roller with at least one groove. The edge strip constraint 61 preferably has two grooves. The edge strip 9 can be wound around the two grooves once. This will not change the direction of the edge strip 9, but will also increase the winding resistance of the edge strip 9. The resistance provided by the edge strip constraint 61 to the movement of the edge strip 9 ensures that the edge strip 9 is in a taut state when it is wound by the edge strip winding machine 5, thereby ensuring the flatness of the winding.

[0050] In the above embodiments, the drive sources for the conveyor roller 2, finished product winding roller 3, edge cutting knife 4, edge strip winding device 5, and smooth rod winding device 6 mentioned in this application can be independent structures or interconnected mechanisms, such as a single driven motor, multiple gear meshing drives, belt drives, or chain drives, etc., and the smooth rod winding device 6 itself can also adjust the frequency and stroke of its reciprocating motion. This application allows the polyimide film to be slit into finished film 8 and edge strips 9, and simultaneously winds both up, ensuring smooth production of the equipment.
