Description

Technical Field

[0001] The present invention relates to the technical field of winding equipment for flexible insulating base films of flexible printed circuit boards, and particularly to a winding device for insulating base films of flexible copper clad laminates. Background Art

[0002] Flexible copper clad laminate (FCCL), also known as flexible copper clad laminate or soft copper clad laminate, is a copper clad laminate formed by bonding copper foil to one or both sides of a flexible insulating material through a specific process, and is widely used in fields such as 5G communication equipment, navigation and positioning equipment, and smartphones that require flexible printed circuit boards. Flexible copper clad laminate mainly consists of three parts: an insulating base film, copper foil, and an adhesive. After production, the insulating base film is wound by a winding shaft and then put into the production of flexible copper clad laminate. In the prior art, the winding of the insulating base film usually requires the use of a winding rack. A rotating drive (usually a drive motor) is generally provided on the winding rack. Both ends of the winding shaft are rotatably mounted on the winding rack and one end is connected to the rotating drive. The operation of the rotating drive causes the winding shaft to rotate to wind the insulating base film. When a roll of insulating base film is wound up, generally, the insulating base film needs to be cut off and then the next winding shaft is replaced to continue winding. During cutting, a cutter that moves up and down can generally be used. However, during the cutting process, the winding needs to stop while the production of the insulating base film continues. Although a drive source is provided in the previous process of production to enable the insulating base film to continue to move backward to ensure normal production without stopping, this causes the moving insulating base film to accumulate at the cutter position, affecting the normal cutting process. At the same time, the end of the cut insulating base film will directly fall to the ground, which may cause scratches. Summary of the Invention

[0003] Aiming at the deficiencies in the prior art, the present invention provides a winding device for insulating base films of flexible copper clad laminates, which solves the problems in the prior art that non-stop operation during the cutting of the insulating base film may affect the normal cutting process and cause scratches due to the falling of the end of the insulating base film.

[0004] According to an embodiment of the present invention, a winding device for an insulating base film of a flexible copper clad laminate includes a first mounting plate and a second mounting plate which are fixedly opposed, and a first rotation driver provided on the first mounting plate. The first rotation driver is connected to a docking head that rotates through the first mounting plate. A first support opening opposed to the docking head is recessed on the top surface of the second mounting plate; An upper mounting strip is also fixedly connected between the first mounting plate and the second mounting plate. A vertical top plate is telescopically provided below the upper mounting strip. A cutting knife is provided on the upper mounting strip directly above the vertical top plate, and the cutting knife has a knife head facing downward; It also includes a boosting roller and a supporting strip provided between the first mounting plate and the second mounting plate. The boosting roller and the first rotation driver are arranged on both sides of the upper mounting strip. The boosting roller rotates self - rotatably. The supporting strip is also provided with an upwardly curved surface. The supporting strip is vertically telescopically arranged below the boosting roller, and during the telescoping process, the upwardly curved surface can approach or move away from the lower roller surface of the boosting roller. The docking head and the first support opening are used for installing a winding shaft. During the winding process, the insulating base film sequentially passes between the boosting roller and the supporting strip, between the cutting knife and the vertical top plate, and then is wound around the winding shaft. At the same time, the insulating base film is in rolling contact with the boosting roller. When cutting is required: the first rotation driver first stops rotating, the boosting roller stops rotating later, the supporting strip then moves upward so that the insulating base film is clamped between the upwardly curved surface and the boosting roller, and then the vertical top plate moves upward to contact the insulating base film and continues to move upward so that the insulating base film is cut by the knife head of the cutting knife. During the cutting process, the insulating base film on both sides of the cutting knife is in a relatively stable state, so it can proceed normally, and the end of the cut insulating base film is clamped by the boosting roller and the supporting strip and will not drop, thus avoiding scratching and solving the problem in the prior art that continuous operation during the cutting of the insulating base film may affect the normal cutting and cause the end of the insulating base film to fall and cause scratching.

[0005] Further, it also includes a lower mounting strip detachably connected to the upper mounting strip. An arc - shaped groove is recessed on the bottom surface of the lower mounting strip. The cutting knife is detachably installed on the lower mounting strip and the knife head is located below the inner top surface of the arc - shaped groove. The upper end of the vertical top plate is provided with an upwardly protruding arc - shaped head. A receiving groove is recessed on the top surface of the arc - shaped head, and the arc - shaped head can be received in the arc - shaped groove so that the knife head abuts into the receiving groove.

[0006] Further, the supporting strip is also provided with a first downwardly curved surface located obliquely above and connected to the upwardly curved surface. The first downwardly curved surface and the upper mounting strip are arranged on both sides of the boosting roller.

[0007] Further, a supporting plate is fixedly connected between the first mounting plate and the second mounting plate. A lower protection plate with both ends fixed to the supporting plate through support rods is also provided on the supporting plate. The vertical top plate is located between the lower protection plate and the supporting plate, and a through - frame for the vertical top plate to penetrate up and down is provided on the lower protection plate. A first telescopic driver is provided below the supporting plate. The first telescopic driver has an output end extending upward, and the output end telescopically passes through the supporting plate and is fixed to the vertical top plate.

[0008] Further, guiding bars are fixedly connected to both ends of the vertical top plate, and the two guiding bars vertically slide through the supporting plate.

[0009] Further, an installation groove is recessed on the top surface of the arc-shaped groove, the cutting knife is inserted into the installation groove, and the cutting knife and the lower installation strip are locked by a first locking member.

[0010] Further, a positioning groove is recessed on the top surface of the upper installation strip, a positioning block that can be inserted into the positioning groove is fixedly arranged on the lower installation strip, and the upper installation strip and the lower installation strip are locked by a second locking member.

[0011] Further, a sleeve is fixedly connected to one end of the docking head facing away from the first rotation driver.

[0012] Further, at least one pair of fixing rods are fixedly connected between the docking head and the sleeve, and a clamping block located between all the fixing rods is also fixedly connected to the docking head.

[0013] Further, the first mounting plate is also fixedly connected with a supporting block located between it and the second mounting plate, and a second supporting port facing the first supporting port is recessed on the top surface of the supporting block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] A boosting roller, a supporting strip, a cutting knife, and a vertical top plate through which the insulating base film passes in sequence are provided. During the winding process, the insulating base film passes between the boosting roller and the supporting strip, and between the cutting knife and the vertical top plate in sequence, and then is wound around the winding shaft. At the same time, the insulating base film is in rolling contact with the boosting roller. When cutting is required: the first rotation driver stops rotating first, the boosting roller stops rotating later, the supporting strip moves upward to clamp the insulating base film between the upper curved arc surface and the boosting roller, and then the vertical top plate moves upward to contact the insulating base film and continue to push upward so that the insulating base film is cut by the cutting head of the cutting knife. During the cutting process, the insulating base film on both sides of the cutting knife is in a relatively stable state, so it can proceed normally, and the end of the cut insulating base film is clamped by the boosting roller and the supporting strip and will not fall, thus avoiding scratches, and solving the problem that continuous operation during the cutting of the insulating base film in the prior art may affect the normal cutting process and cause scratches due to the falling of the end of the insulating base film; after the winding is completed, the winding shaft can be removed faster and a new winding shaft can be replaced, so the overall efficiency is also improved to a certain extent.

Detailed implementation manners

[0026] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0027] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. are based on the orientation or positional relationships shown in the drawings, and are 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, and thus should not be construed as a limitation to the present invention.

[0028] In an exemplary embodiment, as Figure 1-7As shown in the figure, this embodiment provides a winding device for an insulating base film used in a flexible copper clad laminate, which includes a first mounting plate 1 and a second mounting plate 2 that are fixedly opposed to each other, and a first rotation driver 3 provided on the first mounting plate 1. The first rotation driver 3 is connected to a docking head 4 that rotates through the first mounting plate 1. The first rotation driver 3 can be a driving motor, and the rotating shaft of the driving motor is connected to the docking head 4. The docking head 4 rotates and extends between the first mounting plate 1 and the second mounting plate 2. A first support port 5 opposed to the docking head 4 is recessed on the top surface of the second mounting plate 2. The first support port 5 and the docking head 4 are respectively used to support both ends of the winding shaft 6, and the docking head 4 is also connected to the winding shaft 6 so that when the first rotation driver 3 operates, it drives the winding shaft 6 to rotate self - sufficiently, while the other end of the winding shaft 6 is rotatably supported on the first support port 5 to ensure the normal winding of the insulating base film 7. After the winding is completed, the winding shaft 6 is disconnected from the docking head 4, and then the winding shaft 6 can be conveniently removed (removed after the cutting is completed); in a further solution, an upper mounting strip 8 is also fixedly connected between the first mounting plate 1 and the second mounting plate 2. A vertical top plate 9 is telescopically provided below the upper mounting strip 8. A cutter 10 located directly above the vertical top plate 9 is provided on the upper mounting strip 8, and the cutter 10 has a cutting head 11 facing downward. A first telescopic driver 12 for driving it to telescopically move up and down is provided below the vertical top plate 9. When cutting is required, the vertical top plate 9 moves upward and approaches the cutter 10 above; the winding device also includes a boosting roller 13 and a supporting strip 14 provided between the first mounting plate 1 and the second mounting plate 2. The boosting roller 13 and the first rotation driver 3 are arranged on both sides of the upper mounting strip 8. A second rotation driver 15 for driving the boosting roller 13 to rotate self - sufficiently is mounted on the first mounting plate 1. The second rotation driver 15 can also be a driving motor. An upward - curved surface 16 is also provided on the supporting strip 14. A second telescopic driver 17 for driving it to telescopically move up and down is provided below the supporting strip 14 (both the first telescopic driver 12 and the second telescopic driver 17 can be air cylinders). The supporting strip 14 is vertically telescopically provided below the boosting roller 13, and during the telescopic process, the upward - curved surface 16 can approach or move away from the lower roller surface of the boosting roller 13. When winding: the insulating base film 7 passes through between the boosting roller 13 and the supporting strip 14, and between the cutter 10 and the vertical top plate 9 in sequence, and then is wound around the winding shaft 6. At the same time, the insulating base film 7 is in rolling contact with the boosting roller 13 to make the insulating base film 7 move more smoothly in the direction of the winding shaft 6;When it is necessary to cut off at the end of winding: The first rotation driver 3 stops rotating first, and the second rotation driver 15 also stops after a period of time, that is, the assisting roller 13 stops rotating later. In this way, due to the continuous production of the previous process, the insulating base film 7 will move downward and separate from the assisting roller 13. At this time, the second telescopic driver 17 drives the supporting bar 14 to move upward again so that the insulating base film 7 is clamped between the upper bending arc surface 16 and the assisting roller 13. Then, the first telescopic driver 12 drives the vertical top plate 9 to move upward and contact the insulating base film 7 and continue to push upward so that the insulating base film 7 is cut off by the cutting head 11 of the cutter 10. During the cutting process, the insulating base film 7 on both sides of the cutter 10 is fixed due to the stop of the winding roller and the clamping of the assisting roller 13 and the supporting bar 14, and this section of the insulating base film 7 is in an untensioned state. During the upward movement of the vertical top plate 9, the vertical top plate 9 first contacts the insulating base film 7, then gradually moves the insulating base film 7 upward, then re-tensions and smoothly contacts the cutting head 11 of the cutter 10, and then is cut off. The whole process can proceed relatively stably, so the cutting process can proceed normally. After cutting, the end of the insulating base film 7 is clamped by the assisting roller 13 and the supporting bar 14 and will not fall. At the same time, although the end of the insulating base film 7 on the side of the winding roller falls, the position of the winding roller can be set higher to avoid contact with the ground and cause scratching (for the other end, due to continuous production, even if it is at a higher position, it may continue to move downward during subsequent production and may also further contact the ground and cause scratching). Therefore, the insulating base film 7 is not scratched during the whole process, solving the problem in the prior art that non-stop operation during the cutting of the insulating base film 7 may affect the normal cutting process and cause the end of the insulating base film 7 to fall and cause scratching; furthermore, a bottom plate 18 is fixedly connected between the bottoms of the first mounting plate 1 and the second mounting plate 2 to form an inverted U-shaped structure of the overall structure, with better integrity. The bottom plate 18 can also be used for installing the first telescopic driver 12 and the second telescopic driver 17.;

[0029] Such as Figure 1-7As shown, in a further solution, a lower mounting strip 19 detachably connected thereto is further provided below the upper mounting strip 8. The lower mounting strip 19 is used for the detachable connection of the cutting knife 10, which can facilitate the maintenance and repair of the cutting knife 10. Furthermore, an arc-shaped groove 20 is recessed on the bottom surface of the lower mounting strip 19. The cutting knife 10 is detachably mounted on the lower mounting strip 19 and the cutting head 11 is located below the inner top surface of the arc-shaped groove 20. The whole cutting knife 10 does not protrude downward below the lower mounting strip 19. In this way, during the winding process, the insulating base film 7 will not accidentally contact the cutting knife 10, avoiding accidents. At the same time, an upwardly protruding arc-shaped head 21 is provided at the upper end of the vertical top plate 9. The arc-shaped head 21 contacts the insulating base film 7 during the upward pushing process, which can avoid causing additional damage to the insulating base film 7. Furthermore, a receiving groove 22 is recessed on the top surface of the arc-shaped head 21, and the arc-shaped head 21 can be received in the arc-shaped groove 20 so that the cutting head 11 abuts into the receiving groove 22 (the cutting head 11 and the receiving groove 22 can be V-shaped, and the receiving groove 22 is slightly larger for the cutting head 11 to enter smoothly). When cutting, the arc-shaped head 21 pushes the insulating base film 7 upward and abuts into the receiving groove 22, and then the insulating base film 7 contacts the cutting head 11 and is thus cut off; furthermore, an installation groove is recessed on the top surface of the arc-shaped groove 20. The cutting knife 10 is pushed into the installation groove and the cutting knife 10 and the lower mounting strip 19 are locked by a first locking member 23. The first locking member 23 can be a bolt. A recessed groove 24 can also be provided on one side of the lower mounting strip 19. The first locking member 23 is locked through the recessed groove 24, and the end of the first locking member 23 can be located in the recessed groove 24 without being exposed; in a further solution, a positioning groove is recessed on the top surface of the upper mounting strip 8. A positioning block 25 that can be inserted into the positioning groove is fixedly provided on the lower mounting strip 19, and the upper mounting strip 8 and the lower mounting strip 19 are locked by a second locking member 26. The cooperation between the positioning block 25 and the positioning groove plays a role in positioning the lower mounting strip 19, enabling the lower mounting strip 19 and the upper mounting strip 8 to be aligned more conveniently, and then locked by the second locking member 26. Similarly, the second locking member 26 can also be a bolt.

[0030] As Figure 1-7As shown, in a further solution, a support plate 27 is fixedly arranged below the lower mounting strip 19. Both ends of the support plate 27 are fixed to the first mounting plate 1 and the second mounting plate 2. A lower guard plate 29 is also arranged on the support plate 27, and both ends of the lower guard plate 29 are fixed to the support plate 27 through support rods 28 respectively. The vertical top plate 9 is located between the lower guard plate 29 and the support plate 27, and a through frame 30 for the vertical top plate 9 to penetrate up and down is arranged on the lower guard plate 29. The first telescopic driver 12 is located below the support plate 27. The first telescopic driver 12 has an output end extending upward, and the output end penetrates through the support plate 27 and is fixed to the vertical top plate 9 after that. In this way, the driving of the vertical top plate 9 is realized. At the same time, it makes the vertical top plate 9 located between the support plate 27 and the lower guard plate 29 initially, avoiding the contact between the insulating base film 7 and the vertical top plate 9. More specifically, the top surface of the lower guard plate 29 can also be a downwardly curved arc surface to avoid more serious scratches caused by accidental contact of the insulating base film 7. Further, guide strips 31 are fixedly connected to both ends of the vertical top plate 9. The two guide strips 31 slide vertically through the support plate 27. The two guide strips 31 can provide vertical guidance during the movement of the vertical top plate 9, so that the movement is carried out more smoothly.

[0031] As Figure 1-7 shown, more specifically, in this solution, the upwardly curved arc surface 16 and the assisting roller 13 arranged on the support strip 14 provide a larger area of clamping contact for the insulating base film 7, playing a stabilizing role while avoiding causing additional damage to the insulating base film 7. Further, a first downwardly curved arc surface 32 is also arranged on the support strip 14, which is located obliquely above and connected to the upwardly curved arc surface 16. The first downwardly curved arc surface 32 and the upper mounting strip 8 are arranged on both sides of the assisting roller 13. The arranged first downwardly curved arc surface 32 can lift the insulating base film 7 upward during cutting. Continuing production will cause the insulating base film 7 to droop downward on the side of the first downwardly curved arc surface 32 away from the assisting roller 13, while the first downwardly curved arc surface 32 just provides an upward arc-shaped support. Therefore, it can avoid causing additional damage to the insulating base film 7. Further, a second downwardly curved arc surface 40 connected to the first downwardly curved arc surface 32 is also arranged obliquely below the first downwardly curved arc surface 32. The second downwardly curved arc surface 40 can also lift the insulating base film 7 upward during the upward movement of the support strip 14, and at the same time provide arc-shaped support for the end of the insulating base film 7 after cutting is completed, so as to avoid damage to the insulating base film 7.

[0032] As Figure 1-7As shown, in a more detailed solution, one end of the take-up reel 6 is detachably docked with the docking head 4. After the take-up reel 6 is removed later, a sleeve 33 is fixedly connected to the end of the docking head 4 facing away from the first rotation drive 3. One end of the take-up reel 6 is sleeved with the sleeve 33, and the other end is placed on the first support opening 5. When it needs to be removed, one end of the first support opening 5 is pulled outwards so that the connection between the take-up reel 6 and the sleeve 33 is disconnected, and then it can be removed. A plurality of protruding guide racks 34 can be provided on the inner wall of the sleeve 33, and a corresponding plurality of recessed grooves can be provided on the outer wall of the end of the take-up reel 6 (it can also be set conversely, with the guide racks 34 provided on the take-up reel 6 and the recessed grooves provided on the sleeve 33). When docking, the guide racks 34 slide into the recessed grooves one by one, so that the take-up reel 6 can rotate together with the sleeve 33. On the other hand, at least a pair of fixing rods 35 can be fixedly connected between the docking head 4 and the sleeve 33, and a clamping block 36 located between all the fixing rods 35 is also fixedly connected to the docking head 4. The space between the fixing rods 35 is hollowed out at intervals, and the clamping block 36 can be clearly seen. The provided clamping block 36 is used to dock with the take-up reel 6, that is, a clamping groove for the clamping block 36 to be clamped is provided on the end face of the take-up reel 6. After docking, the clamping block 36 is located in the clamping groove, so that the docking is more stable. The provided clamping block 36 and the clamping groove can also be columns with polygonal cross-sections such as triangular prisms and square columns. After docking, it can better prevent the take-up reel 6 from rotating relative to the sleeve 33 and the docking head 4. At the same time, the hollowing between the fixing rods 35 facilitates observing the position of the clamping block 36, which is convenient for the take-up reel 6 to adjust its position and then quickly insert into the sleeve 33 to achieve docking.

[0033] As Figure 1-8 shown, in a further solution, the first mounting plate 1 is also fixedly connected with a supporting block 37 located between it and the second mounting plate 2. The supporting block 37 can be fixed on the first mounting plate 1 through a plurality of connecting rods 39, or can be fixed on the bottom plate 18. The top surface of the supporting block 37 is recessed with a second support opening 38 facing the first support opening 5. The supporting block 37 is used to provide rotational support for the end of the take-up reel 6 docked with the docking head 4. Especially during the process of removing the take-up reel 6, after the take-up reel 6 is pulled out of the sleeve 33, the take-up reel 6 still remains stable under the support of the first support opening 5 and the second support opening 38, so as to avoid sudden loss of support and dropping at one end. More specifically, both the first support opening 5 and the second support opening 38 are U-shaped structures as a whole, with the upper end open for the take-up reel 6 to be taken and placed.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
