Description

Technical Field

[0001] This invention belongs to the field of copper foil cutting technology, and particularly relates to a double-roll copper foil cutting device. Background Technology

[0002] Copper foil has a wide range of applications. It is typically cut from rolls. Currently, most copper foil cutting machines still cut single rolls, resulting in low production efficiency. A small number of machines can cut double rolls of copper foil to improve efficiency, but these still have certain drawbacks in practical use. For example, the double-roll copper foil cutting machine in patent number CN105565036B uses several merging and pressing rollers to stack and merge the double rolls of copper foil before cutting the double layers to improve efficiency. However, due to the ductility of copper foil, during stacking and cutting, the external force of the cutting blade squeezes the double layers of copper foil, causing them to fuse together. When using the finished product, it is difficult to separate the double layers of copper foil, leading to inconvenience. Furthermore, the large number of rollers in the machine increases the overall equipment cost and occupies a large space. Summary of the Invention

[0003] The purpose of this invention is to provide a double-roll copper foil cutting device to solve the above-mentioned problems, which can improve the production efficiency of double-roll copper foil, facilitate subsequent separation and use by workers, enhance practical effect, and reduce the cost and space occupied by copper foil cutting machine equipment.

One end of the trigger is disposed on the trigger, and the other end of the connecting rod passes through the housing and is fixedly connected to the ratchet. When the housing slides along the conveying direction of the padding layer to contact the inner wall of the through groove, the ratchet slides into the groove through the connecting rod. A reset component is disposed between the connecting rod and the housing, and a connector is disposed between the housing and the through groove. The connector is used to adapt to the tension of the padding layer to open and close the trigger.

[0013] Preferably, the connector includes a support rod fixed in the through groove, a support plate slidably connected to the support rod, one end of the support plate extending out of the through groove and fixed to the outer shell, a first contact point being provided on the side wall of the support plate, and a second contact point being provided on the outer wall of the bottom end of the through groove corresponding to the first contact point, and the triggering element being activated when the first contact point contacts the second contact point.

[0020] Compared with the prior art, the present invention has the following advantages and technical effects:

[0021] This invention incorporates a padding conveying unit between two foil feeding mechanisms. The padding layer is conveyed along the copper foil conveying direction by a laying roller. After passing through a merging mechanism, the double-layer copper foil is positioned on both sides of the padding layer. When the cutting mechanism cuts, external force is applied to the merging layer. Due to the presence of the padding layer, the cut points of the two copper foil layers do not fuse together, facilitating separation of the double-layer copper foil during subsequent use. This improves production efficiency while ensuring user convenience. Furthermore, the padding conveying unit is equipped with a force-equalizing component to adjust the tension of the padding layer. During the laying process, the presence of air bubbles between the copper foil and the padding layer is reduced, preventing oxidation of the copper foil by external air and effectively preventing the padding layer from eventually breaking due to increased tension. At the same time, the adhesive roller, which is set to connect the copper foil and the padding layer, applies an adhesive layer to the copper foil, improving the sealing of the copper foil and further enhancing the connection strength between the padding layer and the copper foil. Compared with the traditional method, when the uniform force component tensions the padding layer, the padding layer simultaneously tensions the two copper foils, thereby reducing the need for several rotating rollers that perform the tensioning function and lowering the operating cost.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example: Refer to Figures 1-8 A double-roll copper foil cutting device includes a work platform 1, and further includes...

[0035] Two foil feeding mechanisms are set on the working platform 1. The foil feeding mechanisms are raised and lowered relative to the working platform 1. The two foil feeding mechanisms convey copper foil 2 in the same direction and at the same speed.

[0036] The padding layer conveying unit is set between the two foil feeding mechanisms. The padding layer conveying unit includes a laying roller 4 that is connected to the working platform 1. The laying roller 4 is equipped with a force equalization component. The force equalization component has an adjustment end, which is used to adjust the tension of the padding layer 3. The padding layer 3 and the copper foil 2 are conveyed synchronously.

[0037] Among them, each of the two foil feeding mechanisms is provided with a glue-applying roller 5 on one side of the adjacent laying roller 4. The glue-applying roller 5 can slide adjustablely relative to the foil feeding mechanism.

[0038] A merging mechanism is set in the conveying direction of copper foil 2. After passing through the merging mechanism, copper foil 2 and pad 3 form a merged layer.

[0039] The cutting mechanism is located at the output end of the merging mechanism and is used to cut the merged layers.

[0040] This invention establishes a padding layer conveying unit between two foil feeding mechanisms. A laying roller 4 conveys the padding layer 3 along the copper foil 2 conveying direction. After passing through a merging mechanism, the double-layer copper foil 2 is positioned on both sides of the padding layer 3. When the cutting mechanism cuts, external force is applied to the merging layer. Due to the presence of the padding layer 3, the cut points of the two copper foil layers 2 do not fuse together, facilitating separation of the double-layer copper foil 2 during subsequent use. This improves production efficiency while ensuring user convenience. Furthermore, the padding layer 3 conveying unit is equipped with a force-equalizing component to adjust the laying tension of the padding layer 3. During installation, the presence of air bubbles between the copper foil 2 and the pad 3 is reduced to prevent oxidation of the copper foil 2 by the outside air. This also effectively prevents the pad 3 from eventually breaking due to increased tension. At the same time, the adhesive roller 5, which is set to connect the copper foil 2 and the pad 3, applies an adhesive layer to the copper foil 2, improving the sealing of the copper foil 2 and further enhancing the connection strength between the pad 3 and the copper foil 2. Compared with the traditional method, when the uniform force component tensions the pad 3, the pad 3 simultaneously tensions the two copper foils 2, thereby reducing the need for several rotating rollers that perform the tensioning function and lowering the operating cost.

[0041] In this technical solution, the pad 3 is preferably, but not limited to, made of materials such as PVC, polyimide, and polyethylene, which have insulation properties and sufficient tension to ensure the implementation of the uniform force application component to tension the pad 3.

[0042] Furthermore, the two ends of the laying roller 4 are respectively set on two fixed seats 6, the fixed seats 6 are fixedly connected to the working platform 1, the force uniform application component is set at one end of the laying roller 4 that extends into the fixed seat 6, and the fixed seat 6 is provided with an adaptive control component corresponding to the force uniform application component. The adaptive control component is used to control the tension to be released at the adjustment end when the pad layer 3 reaches the tension extreme value.

[0043] After the uniform force application component tensions the pad 3, as the laying roller 4 continuously conveys the pad 3 between the double-layer copper foil 2, the shaft diameter of the pad 3 on the laying roller 4 gradually decreases. When the laying roller 4 rotates, the tension on the pad 3 gradually increases, causing the pad 3 to exceed the tension limit and break. At this time, the adaptive control component on the uniform force application component detects the tension on the pad 3 and controls the adjustment end to release the tension before reaching the breakage limit. This achieves uniform laying of the tensioned pad 3 while avoiding breakage of the pad 3 and reducing laying efficiency. It also prevents the copper foil 2 from melting during cutting and seals the copper foil 2. Furthermore, the copper foil 2 adheres to the pad 3, and the pad 3 is tensioned simultaneously, improving the service life of the copper foil 2 and reducing the number of double-roll copper foil cutting devices used, thus reducing operating costs.

[0044] In one embodiment of the present invention, the adaptive control component of the uniform force application component may preferably, but is not limited to, use a tension detector to detect the rotational tension of the laying roller 4. After detecting the extreme value of breakage, the uniform force application component is controlled by an external execution program (such as a computer, coding control module, etc.) to release the tension, thereby improving the adjustment efficiency.

[0045] Furthermore, grooves are provided at both ends of the laying roller 4. The force-equalizing component includes a ratchet 7 that slides in the groove. The laying roller 4 rotates relative to the ratchet 7. Several locking protrusions 8 are provided circumferentially on the inner sidewall of the groove. The locking protrusions 8 are adapted to the tooth grooves of the ratchet 7. The locking protrusions 8 are elastic support structures. The ratchet 7 and the locking protrusions 8 are selectively engaged or not in contact. A torque member is provided between the ratchet 7 and the inner wall at the bottom of the groove. The torque member is connected to the adaptive control member. When the torque member reaches the maximum torque value, the ratchet 7 and the locking protrusions 8 are not in contact. When the torque member has a torsional load, the ratchet 7 and the locking protrusions 8 are engaged.

[0046] By setting the uniform force application component as a ratchet 7 and a locking protrusion 8 meshing structure, after the torque component reaches the torsional load, the ratchet 7 and the locking protrusion 8 lock and no longer rotate. The laying roller 4 is fixed relative to the ratchet 7, avoiding the breakage of the padding layer 3. At the same time, the adaptive control component connected to the torque component transmission controls the ratchet 7 and the locking protrusion 8 to no longer contact each other. When the torque component resets and generates torque, the laying roller 4 rotates relative to the ratchet 7 to release the tension load of the padding layer 3, realizing the self-adjustment of tension. Compared with the tension detector, this further reduces the amount of equipment used and lowers the production cost.

[0047] In this technical solution, the cam 8 preferably uses a spring plate or a flexible plate, and the two ends of a pressure spring 9 are fixedly connected between the cam 8 and the laying roller 4.

[0048] Furthermore, a through groove is provided on the fixed base 6, and the adaptive control component includes a housing 11 slidably disposed in the through groove. The sliding direction of the housing 11 is the same as the conveying direction of the pad 3. A trigger is provided inside the housing 11. The trigger is an electrically activated structure. One end of a connecting rod 12 is provided on the trigger. The other end of the connecting rod 12 passes through the housing 11 and is fixedly connected to the ratchet 7. When the housing 11 slides along the conveying direction of the pad 3 to contact the inner wall of the through groove, the ratchet 7 slides into the groove through the connecting rod 12. A reset component is provided between the connecting rod 12 and the housing 11. A connector is provided between the housing 11 and the through groove. The connector is used to adapt to the tension opening and closing trigger of the pad 3.

[0049] Furthermore, the connector includes a support rod 13 fixed in the through groove, a support plate 14 slidably connected to the support rod 13, one end of the support plate 14 extending out of the through groove and fixed to the outer shell 11, a first contact 15 is provided on the side wall of the support plate 14, and a second contact 16 is provided on the outer wall of the bottom end of the through groove corresponding to the first contact 15. When the first contact 15 contacts the second contact 16, the trigger is opened.

[0050] The two ends of the support spring 17 are fixedly connected to the inner wall of the through groove near the second contact 16 and the support plate 14 respectively. A damping slide shaft 18 is provided on the side wall of the support plate 14 away from the first contact 15. The damping slide shaft 18 is in sliding contact with the through groove.

[0051] Furthermore, the torsion component includes a torsion spring 10, and a damping bearing 19 is provided on the side of the housing 11 near the groove. One end of the support rod 20 is fixedly connected to the rotating end of the damping bearing 19, and the other end of the support rod 20 extends into the groove and is fixedly connected to the laying roller 4. The support rod 20 is slidably connected to the ratchet 7. The torsion spring 10 is wound around the support rod 20, and both ends of the torsion spring 10 are fixedly connected to the ratchet 7 and the laying roller 4, respectively. The reset component includes a reset spring 21 wound around the connecting rod 12, and both ends of the reset spring 21 are fixedly connected to the housing 11 and the ratchet 7, respectively.

[0052] Reference Figures 3-6 As the pad 3 is continuously laid together with the copper foil 2, the pad 3 drives the laying roller 4 to rotate. During the rotation of the laying roller 4, the torsion spring 10 is gradually tensioned, and the laying roller 4 is prevented from resetting under the engagement of the ratchet 7 and the locking protrusion 8. As the shaft diameter of the pad 3 on the laying roller 4 decreases, the rotational tension of the torsion spring 10 increases to the extreme value of torsion, and the laying roller 4 is fixed to the ratchet 7. The pad 3 continues to pull the laying roller 4. At this time, the laying roller 4 does not rotate, and drives the outer shell 11 to slide in the chute in the conveying direction of the pad 3. The outer shell 11 drives the support plate 14 to slide along the support rod 13 and squeeze the support spring 17. As the outer shell 11 continues to slide, the first contact point 15 on the support plate 14 contacts the second contact point 16 on the outer wall of the bottom end of the chute to form a passage. The electrical circuit activates the trigger, which drives the connecting rod 12 to slide the ratchet 7 out of the groove, preventing it from continuing to abut against the locking protrusion 8. As a result, the laying roller 4 is reset under the action of the torsion spring 10. After resetting, the laying roller 4 rotates, the tension of the pad 3 is released, and the laying roller 4 is no longer stretched. The laying roller 4 no longer squeezes the outer shell 11. Under the action of the support spring 17, the first contact 15 and the second contact 16 no longer contact each other, the trigger is de-energized, and then the reset spring 21 drives the connecting rod 12 to extend out of the outer shell 11. The ratchet 7 re-enters the groove and re-engages with the locking protrusion 8 as the laying roller 4 rotates, repeatedly providing tension to the pad 3, ensuring the smooth laying and merging of the copper foil 2, and thus improving the subsequent cutting effect.

[0053] It is understandable that a damping bearing 19 is provided at the connection end between the support rod 20 and the outer shell 11, and a damping slide shaft 18 is provided between the support plate 14 and the through groove to slow down the reset speed of the laying roller 4 when the tension is released, so as to avoid the pad layer 3 from breaking due to the action of the reset spring 21, the support spring 17 and the torsion spring 10. The damping bearing 19 and the damping slide shaft 18 mentioned above are existing technologies and will not be described in detail.

[0054] In one embodiment of the present invention, the trigger is preferably an electromagnet 35, which fixes the magnetic block 36 to the connecting rod 12. After being energized, the electromagnet 35 attracts the magnetic block 36 to extend the ratchet 7 out of the groove through the connecting rod 12. Alternatively, a micro-rotating motor can be used to drive the tension rope, with one end of the tension rope extending into the outer shell 11 and fixed to the ratchet 7. This allows the ratchet 7 to slide relative to the groove after the first contact 15 and the second contact 16 come into contact. It is understood that in this technical solution, the first contact 15 is directly connected to the driving part of the trigger through a wire, and the second contact 16 is connected to the power supply. After the first contact 15 and the second contact 16 come into contact, a current path is formed. When the first contact 15 and the second contact 16 are separated and not in contact, no conductivity occurs, thus improving the safety of the equipment.

[0055] Furthermore, the foil feeding mechanism includes two opposing support seats 22. A lifting component is provided between the bottom end of the support seat 22 and the working platform 1. A feeding roller 24 is connected between the two support seats 22. One end of the feeding roller 24 passes through the support seat 22 and is fixedly connected to the output shaft of the drive motor 25. The drive motor 25 is fixedly connected to the support seat 22. A sliding groove is provided at the bottom of the support seat 22. The glue coating roller 5 slides in the sliding groove. A locking component is provided on the glue coating roller 5. The glue coating roller 5 is fixed to the support seat 22 by the locking component.

[0056] Start the drive motor 25 to rotate the feeding roller 24 and convey the copper foil 2 towards the merging mechanism. During the process, the copper foil 2 slides and contacts the coating roller 5 to complete the coating and is then laid together with the padding layer 3. Adjust the position of the coating roller 5 by locking the locking device so that the side of the copper foil 2 adjacent to the padding layer 3 can have the coating pressure to ensure the coating effect.

[0057] Furthermore, the locking component includes an adjusting seat 26 that is slidably connected to the slide groove. The two ends of the glue-applying roller 5 are respectively connected to the two adjusting seats 26 that are arranged opposite to each other. An adjusting bolt 28 is connected to the upper limit of the outer wall of the adjusting seat 26. One end of the adjusting bolt 28 extends into the adjusting seat 26 and is threadedly connected to a sliding sleeve 29. A support column 30 is provided inside the adjusting seat 26 corresponding to the sliding sleeve 29. One end of the support column 30 extends out of the adjusting seat 26 and abuts against the inner wall of the slide groove.

[0058] Reference Figure 7 , Figure 8 Rotate the adjusting bolt 28 to prevent the sliding sleeve 29 from contacting the support column 30, thereby allowing the adjusting seat 26 to slide within the groove. When fixing, simply turn the adjusting bolt 28 in the opposite direction to make the sliding sleeve 29 slide and contact the support column 30. The support column 30 extends out of the adjusting seat 26 and contacts the inner wall of the groove to complete the fixing of the glue roller 5. Correspondingly, a limiting post 27 is fixedly connected to the support column 30, and a limiting groove is opened on the inner wall of the groove corresponding to the limiting post 27.

[0059] Furthermore, the merging mechanism has two sets of clamping rollers arranged sequentially along the copper foil 2 conveying direction. The clamping roller set includes two opposing first clamping rollers 31 and second clamping rollers 32. The first clamping rollers 31 and second clamping rollers 32 are arranged sequentially from top to bottom. The two copper foils 2 and the pad layer 3 are all connected to the clamping channel formed by the adjacent first clamping rollers 31 and second clamping rollers 32.

[0060] Furthermore, the cutting mechanism includes a cutting table 33 connected to the output end of the pressing channel, with a blade holder fixed to each side of the cutting table 33, and a cutting blade 34 disposed between the two blade holders.

[0061] The double-layer copper foil 2 and the padding layer 3 are pressed together by the first pressing roller 31 and the second pressing roller 32. The pressed combined layer is subjected to the tension of the two sets of first pressing roller 31 and second pressing roller 32 arranged in sequence to prevent the copper foil 2 from shrinking after cutting and to ensure cutting efficiency. Cutting is performed intermittently by the cutting blade 34 to ensure production efficiency. It is understood that the blade holder is equipped with a control component to drive the cutting blade 34 to cut. The control component is existing technology and will not be described in detail.
