Description

Technical Field

[0001] This invention belongs to the field of FPC production technology, and relates to a self-correcting winding device and its application in FPC production. Background Technology

[0002] As the name suggests, winding is the process of rolling up long strips of material to facilitate storage, transfer, and subsequent use. It is used in various fields, such as the copper foil in the FPC production process, which is wound up using winding equipment.

[0003] After the material to be wound (such as copper foil or other materials) is produced, a tube (such as a paper tube) for winding the material is usually fitted onto the outer wall of a support shaft. Then, the end of the material (using tape) is wrapped around the tube. The material is then wound and wound up during production. However, during the production process, it is usually impossible to guarantee that the material will move continuously and stably in the required direction. Instead, a certain degree of deviation will usually occur. At this time, a position sensor is usually installed upstream of the support shaft to sense the edge position of the material (usually through photoelectric, laser, or ultrasonic detection). When the deviation of the material edge position is sensed, the support shaft will move horizontally under the drive of the motor and lead screw, so that the material can be wound more aligned and wound around the support shaft. Summary of the Invention

[0018] The telescopic mechanism includes a plurality of driving parts evenly arranged on the outer wall of the support part. The longitudinal section of each driving part is fan-shaped, and the outer side of each driving part is movably attached to the inner side of a telescopic member. Both the telescopic member and the driving part are elongated. Both ends of the telescopic member are provided with reset parts. The inner wall of the outer cylinder is provided with a reset groove. Each reset part is movably located in a reset groove. An elastic member that is continuously in a compressed state is provided between the outer side of the reset part and the outer side of the corresponding reset groove.

[0019] The outer wall of the support portion is provided with a plurality of first termination seats, and the inner wall of the outer cylinder portion is provided with a plurality of second termination seats. The outer cylinder portion includes a first state and a second state.

[0020] When the outer cylinder is in the first state, the elastic member is in the shortest length state, the outer end of the drive part abuts against the middle of the corresponding telescopic member, the outer end of the telescopic member is located outside the telescopic hole, and each second stop seat abuts against a first stop seat.

[0021] When the outer cylinder is in the second state, the inner side of the reset part abuts against the inner wall of the corresponding reset groove, the outer end of the telescopic member is located in the reset groove, the inner side of the telescopic member abuts against the drive part or the support part, and the first termination part and the second termination part are in a separated state.

[0022] The present invention is further configured such that a return spring is sleeved on the outer wall of the support portion, and the two ends of the return spring are respectively connected to the outer wall of the support portion and the inner wall of the outer cylinder portion, and the return spring causes the outer cylinder portion to have a tendency to change from the first state to the second state.

[0025] The present invention also discloses the application of any of the above in FPC production, wherein the support shaft is used for winding copper foil.

[0026] Compared with existing technologies, this invention provides a self-correcting winding device and its application in FPC production. After the material (which can be copper foil or other materials) is produced, it first passes through a position sensor, then sequentially passes through the gaps between the guide roller, the upper correction roller, and the lower correction roller, and finally winds around a cylinder (preferably a paper cylinder, but also a cylinder of other materials) fixedly connected to a support shaft. The ends of the material are then connected to the cylinder using tape or the like. Subsequent material production and the rotation of the support shaft occur simultaneously.

[0027] When the position sensor detects that the material's position is appropriate, the gap between the upper and lower alignment rollers allows the material to pass through (the material does not need to interact with the upper alignment roller). Since the depth of the lower alignment roller is the greatest (i.e., the smallest diameter) in the middle and the depth gradually decreases (i.e., the diameter gradually increases) on both sides, the longitudinal section of the material at the lower alignment roller is a C-shape or arc shape with the opening facing outward. This can guide the material towards the center and increase its centrality (i.e., if the material moves to the sides, it needs to undergo greater deformation, which is more difficult; therefore, the material's own structural characteristics increase the difficulty of the material shifting to the sides).

[0028] When the position sensor detects a material deviation, the drive mechanism moves the upper alignment roller on the sliding shaft. Specifically, if the position sensor detects a leftward deviation, the upper alignment roller moves to the right, with its rotational linear speed exceeding the winding speed of the material on the support shaft. After moving a certain distance, the upper and lower alignment rollers clamp the right side of the material and apply a relatively fast pulling speed, thus pulling the material to the right and centering it. Conversely, if the position sensor detects a rightward deviation, the upper alignment roller moves to the left. In actual use, the upper and lower alignment rollers maintain a certain clamping length when clamping the material's edge, effectively clamping it with a line, thus preventing material breakage and ensuring proper winding.

The middle part of the upper correction roller 10 has the largest diameter compared to the rest of the roller, and the diameter of the rest of the roller decreases as the distance from the middle part increases.

[0053] The drive mechanism 11 is used to drive the upper correction roller 10 to move horizontally, and to make one end or the other end of the upper correction roller 10 abut against the lower correction roller 7, or the upper correction roller 10 and the lower correction roller 7 are in a separated state, and the material to be wound passes around the guide roller 5 and the lower correction roller 7 in sequence and is then wound around the support shaft 2.

[0054] It also includes a vertical second support plate 12, and both ends of the lower correction roller 7 are horizontally provided with first rotating shafts 13, and the two first rotating shafts 13 are respectively rotatably connected to the first support plate 1 and the second support plate 12.

[0055] The free end of the sliding shaft 9 is provided with a second rotating shaft 14, which is horizontally rotatably connected to the second support plate 12.

[0056] The drive mechanism 11 includes an electric push rod or a drive cylinder horizontally disposed on the second support plate 12. A vertical drive ring 15 is disposed on the piston rod of the electric push rod or the drive cylinder. The sliding shaft 9 passes through the drive ring 15. The drive ring 15 is rotatably connected to one end of the upper correction roller 10 near the second support plate 12.

[0057] The support shaft 2 includes a support part 2a and an outer cylinder part 2b. The support part 2a is rotatably connected to the first support plate 1, and the outer cylinder part 2b is rotatably connected to the outer wall of the support part 2a. The telescopic hole 3 is opened in the outer cylinder part 2b.

[0058] Two support disks 16 are provided on the outer wall of the support part 2a, and two rotating grooves are opened on the inner wall of the outer cylinder part 2b. The periphery of the two support disks 16 respectively movably fits into the inner wall of the two rotating grooves.

[0059] The telescopic mechanism includes a plurality of drive parts 17 evenly arranged on the outer wall of the support part 2a. The longitudinal section of each drive part 17 is fan-shaped, and the outer side of each drive part 17 is movably attached to the inner side of a telescopic member 4. Both the telescopic member 4 and the drive parts 17 are elongated. Both ends of the telescopic member 4 are provided with reset parts 18. The inner wall of the outer cylinder part 2b is provided with a reset groove 19. Each reset part 18 is movably located in a reset groove 19. An elastic member 20 that is continuously in a compressed state is provided between the outer side of the reset part 18 and the outer side of the corresponding reset groove 19.

[0060] The outer wall of the support portion 2a is provided with a plurality of first termination seats 21, and the inner wall of the outer cylinder portion 2b is provided with a plurality of second termination seats 22. The outer cylinder portion 2b includes a first state and a second state.

[0061] When the outer cylinder 2b is in the first state, the elastic member 20 is in the shortest length state, the outer end of the driving part 17 abuts against the middle of the corresponding telescopic member 4, the outer end of the telescopic member 4 is located outside the telescopic hole 3, and each second termination seat 22 abuts against a first termination seat 21.

The two ends of the return spring 23 are connected to the outer wall of the support portion 2a and the inner wall of the outer cylinder portion 2b, respectively. The return spring 23 causes the outer cylinder portion 2b to have a tendency to change from the first state to the second state.

[0064] The outer wall of the telescopic member 4 is provided with a plurality of pointed anti-slip tips 24. The inner side of the telescopic member 4 is arc-shaped. An extension post 25 is provided at the end of the outer cylinder 2b away from the first support plate 1. A temporary hole 26 is horizontally opened at the free end of the extension post 25. A disc-shaped temporary chamber 27 is coaxially opened at the inner end of the temporary hole 26. The diameter of the temporary chamber 27 is larger than the diameter of the temporary hole 26. A temporary plate 28 that matches the shape of the temporary chamber 27 is provided inside the temporary chamber 27. A set pressure is between the outer surface of the temporary plate 28 and the inner wall of the temporary chamber 27. A temporary post 29 that moves through the temporary hole 26 is provided on the side of the temporary plate 28. A temporary ring 30 is provided at the free end of the temporary post 29. The temporary ring 30 is located outside the extension post 25.

[0065] A motor frame is provided on the side of the first support plate 1 away from the upper correction roller 10. A winding motor 31 is provided on the motor frame. The output shaft of the winding motor 31 is connected to the support shaft 2. A drive wheel 32 is provided on the output shaft of the winding motor 31. A driven wheel 33 is provided on the upper correction shaft 8. A steering shaft 34 is horizontally provided on the first support plate 1. A first steering wheel 35 and a second steering wheel 36 are rotatably provided on the steering shaft 34. The first steering wheel 35 and the second steering wheel 36 are fixedly connected. A transmission belt 37 is sleeved on the outer wall of the first steering wheel 35 and the drive wheel 32. The bottom of the second steering wheel 36 meshes with the top of the driven wheel 33. The linear velocity of the upper correction roller 10 is greater than the linear velocity of the outer cylinder 2b.

[0066] The present invention also discloses the application of any of the above in FPC production, wherein the support shaft 2 is used to wind copper foil; however, it should also be noted that this application is not limited to the production of copper foil, and can also be used in the winding of other sheet materials, such as cloth, plastic, etc., depending on the actual situation, without making too many limitations here.

[0067] This invention provides a self-correcting winding device and its application in FPC production. After the material (which can be copper foil or other materials) is produced, it first passes through a position sensor 6, then sequentially passes through the gap between the steering roller 5, the upper correction roller 10, and the lower correction roller 7, and finally winds around a cylinder (preferably a paper cylinder, but also a cylinder of other materials) fixedly connected to a support shaft 2. The end of the material is then connected to the cylinder using tape or the like. Subsequent material production and the rotation of the support shaft 2 occur simultaneously.

[0068] When the position sensor 6 detects that the material's position is appropriate, the gap between the upper correction roller 10 and the lower correction roller 7 is used for the material to pass through (the material does not need to interact with the upper correction roller 10). Since the depth of the middle part of the lower correction roller 7 is the greatest (i.e., the diameter is the smallest), and the depth on both sides gradually decreases (i.e., the diameter gradually increases), the longitudinal section of the material located at the lower correction roller 7 is a C-shape or arc shape with the opening facing outward. This can guide the material towards the center and increase the material's centering (i.e., if the material moves to the sides, it needs to undergo greater deformation, which is more difficult; therefore, the material's own structural characteristics increase the difficulty of the material shifting to the sides).

[0069] When position sensor 6 detects a material deviation, drive mechanism 11 drives upper correction roller 10 to move on sliding shaft 9. Specifically, if position sensor 6 detects a material deviation to the left, upper correction roller 10 moves to the right, and the linear speed of rotation of upper correction roller 10 is greater than the winding speed of material by support shaft 2. After moving a certain distance, upper correction roller 10 and lower correction roller 7 clamp the right side of the material and apply a relatively fast pulling speed to the right, thus pulling the material to the right and bringing the deviated material to the center position. Conversely, if position sensor 6 detects a material deviation to the right, upper correction roller 10 moves to the left. In actual use, upper correction roller 10 and lower correction roller 7 have a certain clamping length when clamping the edge of the material, i.e., they clamp the material linearly, which effectively prevents material breakage and ensures normal winding.

[0070] In actual use, before the paper tube is fitted onto the support shaft 2, the outer tube 2b is in a second state under the elastic force of the return spring 23, meaning that the telescopic member 4 and the anti-slip tip 24 are both located inside the telescopic hole 3. This makes it easy to fit the paper tube onto the support shaft 2. Afterwards, the worker manually pulls the end of the material and passes it around the guide roller 5 and the lower correction roller 7, then uses tape to attach it to the outer wall of the paper tube. Next, a rod is passed through the temporary ring 30 and pulled outwards or pushed inwards, creating friction between the temporary plate 28 and the inner wall of the temporary chamber 27. At this point, the winding motor 31 can be started, allowing the support 2a to rotate slowly.

[0071] During the slow rotation of the support 2a, the temporary plate 28 applies a certain frictional force to the temporary chamber 27, allowing the outer cylinder 2b to temporarily maintain its angle. This allows the fan-shaped drive 17 to drive the telescopic member 4 outwards until the first stop seat 21 contacts the second stop seat 22. At this point, the anti-slip tip 24 is also inserted into the paper tube, and there is a certain pressure between the telescopic member 4 and the paper tube. The rod can then be pulled out of the temporary ring 30. Even when the support 2a rotates, and the outer cylinder 2b rotates simultaneously with the support 2a, the rod does not rotate with the outer cylinder 2b because the temporary plate 28 and the temporary chamber 27 can rotate relative to each other, preventing injury to workers. During subsequent winding, the lower alignment roller 7 is driven by the support shaft 2 to rotate, and the material passes around the steering roller 5 and the lower alignment roller 7 in sequence. At the same time, the material will change shape when passing the lower alignment roller 7, which increases the resistance of the material winding on the support shaft 2. Therefore, even though the return spring 23 has the tendency to drive the outer cylinder 2b and the support 2a to rotate relative to each other, the force of the return spring 23 is small, and the direction of rotation of the support 2a is to the direction of the extension member 4. Therefore, even after the rod is pulled out of the temporary ring 30, the support 2a and the outer cylinder 2b can still maintain relative stability.

[0072] During the winding process, the drive belt 37 (which can be a belt, chain, or gear belt) drives the first steering wheel 35 (which can be a sprocket or a regular wheel) to rotate, while the second steering wheel 36 (preferably a gear) drives the driven wheel 33 (preferably a gear) and the upper guiding roller 10 to rotate. Simultaneously, the driving wheel 32 has a larger diameter, and the second steering wheel 36 also has a larger diameter, thus allowing the upper guiding roller 10 to have a higher rotational speed. The upper guiding roller 10 does not act on the material in standby mode, but when correcting the material, it can apply a relatively fast traction speed to the material and smoothly guide it to the correct direction.

[0073] After winding, the end of the material is attached to the outer wall of the material roll. At this time, under the elastic force of the return spring 23, the support part 2a and the outer tube part 2b move relative to each other (at the same time, the worker can also assist in rotating the outer tube part 2b by pushing and pulling the temporary ring 30). This causes the outer end of the drive part 17 to be misaligned with the inner end of the telescopic member 4. At this time, under the elastic force of the elastic member 20, the telescopic member 4 moves towards the support part 2a until the telescopic member 4 and the anti-slip tip 24 move into the telescopic hole 3. In this way, the paper tube can be easily removed from the outer tube part 2b.

[0074] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0075] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
