Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing equipment technology, specifically to an anti-wrinkle pressing device. Background Technology

[0002] In the production of products such as circuit boards, flexible circuit boards, and lithium batteries, hot pressing or pressure holding is often required. To improve production efficiency, some equipment uses a roll-to-roll production method, with protective films and auxiliary materials placed on both sides of the product to prevent damage during hot pressing. In some roll-to-roll laminating equipment, to further improve production efficiency, multiple rolls of products are fed side-by-side into the laminating mechanism for pressing or pressure holding. These machines often share a protective film between two side-by-side products, resulting in an excessively wide protective film. An excessively wide protective film is prone to shrinkage and wrinkling during lamination due to uneven stress or heating. These wrinkles can transfer onto the product during lamination, leading to defects and reduced yield. Therefore, a new multi-roll side-by-side roll-to-roll lamination solution is needed to address these technical problems. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-wrinkle pressing device that can prevent wrinkles from forming on the protective film, ensuring production efficiency while improving product yield.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A wrinkle-resistant pressing device includes a feeding mechanism, a pressing mechanism, and a discharging mechanism. The feeding mechanism is used to feed the roll of product to be pressed. The feeding mechanism includes at least one feeding assembly, and the feeding assembly includes at least two feeding shafts. Two product rolls are respectively disposed on the two feeding shafts. The product rolls on the two feeding shafts are staggered by a certain distance in the width direction, so that the products released from the two product rolls enter the pressing mechanism side by side. The pressing mechanism is used to press the products fed by the feeding mechanism. The width of the pressing mechanism is greater than the sum of the width and spacing of the two rolls of products released by the feeding assembly. The discharging mechanism is used to reel in the products after they have been pressed by the pressing mechanism. The discharging mechanism includes a discharging assembly, the number of which corresponds to the number of feeding assemblies. The discharging assembly includes at least two winding shafts. The two winding shafts can reel in two side-by-side products into two rolls that are staggered by a certain distance in the width direction. The feeding assembly further includes a first protective film feeding shaft and a second protective film feeding shaft, and the unloading assembly further includes a first protective film receiving shaft and a second protective film receiving shaft. Both the first and second protective film feeding shafts are used to feed rolls of protective film whose width is greater than the sum of the width and spacing of the two rolls of products fed out by the feeding assembly. The protective film fed out by the first protective film feeding shaft is located on the side of the product facing the upper pressing module of the pressing mechanism, and the protective film fed out by the second protective film feeding shaft is located on the side of the product facing the lower pressing module of the pressing mechanism. The first and second protective film receiving shafts are used to respectively receive the protective film fed out by the first and second protective film feeding shafts into rolls. A slitting mechanism is provided on the conveyor path of both the first and second protective film feeding shafts. The slitting mechanism is used to cut the protective film fed out by the first and second protective film feeding shafts into two segments along the conveyor direction, each with a width matching the width of the two pieces of products fed out by the feeding assembly.

[0005] Compared with the prior art, the beneficial effects of this utility model are as follows: This pressing equipment, by setting a slitting mechanism on both the first and second protective film feeding shafts, can cut a wider protective film into two narrower protective films that match the width of the product. This avoids the probability of the protective film shrinking during the production process due to uneven stress or heating, thus preventing wrinkles from forming on the protective film and preventing wrinkles from being transferred to the product, thereby improving the product yield.

[0006] The aforementioned anti-wrinkle pressing equipment includes a slitting mechanism comprising a slitting blade, a slitting pressure plate, a slitting back roller, and a slitting drive mechanism. The slitting pressure plate and the slitting blade can approach or move away from the slitting back roller under the drive of the slitting drive mechanism. The slitting pressure plate is provided with a blade hole for the blade of the slitting blade to extend out, and the roller surface of the slitting back roller is provided with a clearance groove for the slitting blade to extend into.

[0007] In the aforementioned anti-wrinkle pressing equipment, the slitting blade is a circular blade, which is rotatably mounted on a blade holder, and the blade holder is connected to the slitting drive mechanism.

[0008] In the aforementioned anti-wrinkle pressing device, the cutter holder is provided with an oblong adjustment hole, and the cutter holder is fixedly connected to the slitting drive mechanism by bolts and the adjustment hole.

[0009] The aforementioned anti-wrinkle pressing equipment further includes a dust collection box in the slitting mechanism, which is located directly below the slitting blade.

[0010] The aforementioned anti-wrinkle pressing equipment includes a feeding mechanism comprising at least two sets of feeding components, with multiple sets of feeding components longitudinally distributed on the frame of the feeding mechanism; and a discharging mechanism comprising at least two sets of discharging components, with multiple sets of discharging components longitudinally distributed on the frame of the discharging mechanism.

[0011] In the aforementioned anti-wrinkle pressing equipment, the first protective film feeding shaft of the lower feeding assembly shares a shaft with the second protective film feeding shaft of the adjacent upper feeding assembly, and the first protective film receiving shaft of the lower unloading assembly shares a shaft with the second protective film receiving shaft of the adjacent upper feeding assembly.

[0012] The aforementioned anti-wrinkle pressing equipment includes a protective auxiliary material feeding shaft in the feeding assembly and a protective auxiliary material receiving shaft in the unloading assembly. The protective auxiliary material feeding shaft is used to feed the roll of protective auxiliary material so that the protective auxiliary material is located on the side of the protective film facing the upper pressing module or the lower pressing module. The protective auxiliary material receiving shaft is used to recycle the protective auxiliary material fed out by the protective auxiliary material feeding shaft into a roll.

[0013] The aforementioned anti-wrinkle pressing equipment further includes at least one pull-back mechanism in the feeding mechanism. The pull-back mechanism is located on the conveyor path of the product and is used to pull the product back to tension the product within the pressing mechanism.

[0014] The aforementioned anti-wrinkle pressing equipment further includes a feeding mechanism, which is located on the product's conveyor belt path and is used to pull the product at equal distances.

Detailed Implementation

[0026] The embodiments of this utility model are described in detail below, with reference to Figure 1 , Figure 2 and Figure 8This utility model provides an anti-wrinkle pressing device, including a feeding mechanism 100, a pressing mechanism 200, and a discharging mechanism 300. The feeding mechanism 100 is used to feed the rolls of products to be pressed. The feeding mechanism 100 includes at least one feeding assembly 110, which includes at least two feeding shafts 111. Two product rolls are respectively disposed on the two feeding shafts 111, and the product rolls on the two feeding shafts 111 are staggered by a certain distance in the width direction, so that the products released from the two product rolls enter the pressing mechanism 200 side by side. The pressing mechanism 200 is used to press the products released from the feeding mechanism 100, and the width of the pressing mechanism 200 is greater than the sum of the width and spacing of the two rolls of products released from the feeding assembly 110. The unloading mechanism 300 is used to take the product pressed by the pressing mechanism 200 into rolls. The unloading mechanism 300 includes unloading components 310, the number of which corresponds to the number of loading components 110. The unloading component 310 includes at least two winding shafts 311, which can take two side-by-side products into two rolls that are staggered by a certain distance in the width direction. The loading component 110 also includes a first protective film feeding shaft 112 and a second protective film feeding shaft 113, and the unloading component 310 also includes a first protective film receiving shaft 312 and a second protective film receiving shaft 313. The first protective film feeding shaft 112 and the second protective film feeding shaft 113 are both used to feed rolls of protective film whose width is greater than the sum of the width and spacing of the two rolls of products fed out by the feeding assembly 110. The protective film fed out by the first protective film feeding shaft 112 is located on the side of the product facing the upper pressing module of the pressing mechanism 200, and the protective film fed out by the second protective film feeding shaft 113 is located on the side of the product facing the lower pressing module of the pressing mechanism 200. The first protective film take-up shaft 312 and the second protective film feeding shaft 113 are used to take the protective film fed out by the first protective film feeding shaft 112 and the second protective film feeding shaft 113 into rolls, respectively. A slitting mechanism 120 is provided on the conveyor path of the protective film released from the first protective film feeding shaft 112 and the second protective film feeding shaft 113. The slitting mechanism 120 is used to cut the protective film released from the first protective film feeding shaft 112 and the second protective film feeding shaft 113 into two segments with widths that match the widths of the two products released from the feeding assembly 110, respectively, along the conveyor direction.

[0027] This anti-wrinkle pressing equipment further improves product processing efficiency by feeding two rolls of product material side-by-side into the pressing mechanism 200. A slitting mechanism 120 is installed on the conveyor path of the protective film released from the first protective film feeding shaft 112 and the second protective film feeding shaft 113. The slitting mechanism 120 cuts the wider protective film into two narrower segments matching the width of the two rolls of product, preventing wrinkles caused by uneven shrinkage due to stress or heat during production. These wrinkles are then transferred to the product during the pressing process. This anti-wrinkle pressing equipment can improve product yield while ensuring production efficiency.

[0028] Understandably, the slitting mechanism 120 can slit the protective film using a blade or an electrically heated cutter, depending on the slitting requirements and the specific material of the protective film. (Refer to...) Figures 3 to 6 In this embodiment, the slitting mechanism 120 cuts the protective film using a blade. The slitting mechanism 120 includes a slitting blade 123, a slitting pressure plate 122, a slitting back roller 121, and a slitting drive mechanism 124. The slitting pressure plate 122 and the slitting blade 123 can approach or move away from the slitting back roller 121 under the drive of the slitting drive mechanism 124, and the slitting protective film passes between the slitting pressure plate 122 and the slitting back roller 121. The slitting pressure plate 122 is provided with a blade hole 1221 for the blade of the slitting blade 123 to extend out, and the roller surface of the slitting back roller 121 is provided with a relief groove 1211 for the blade of the slitting blade 123 to enter. During slitting, the slitting drive mechanism 124 drives the slitting pressure plate 122 to approach the slitting back roller 121, pressing the protective film onto the slitting back roller 121, and causing the slitting blade 123 to cut the protective film through the blade exposed by the blade hole 1221 and extend into the relief groove 1211 to complete the slitting of the protective film.

[0029] Reference Figure 3 and Figure 6To ensure a smooth slitting process, guarantee the slitting effect, and avoid burrs at the cut, in this embodiment, the slitting blade 123 is a circular blade. The slitting blade 123 is connected to the slitting drive mechanism 124 via a blade holder 125. The slitting blade 123 and blade holder 125 are rotatably connected, allowing the blade to rotate relative to the protective film along the conveyor belt direction during slitting. In this embodiment, to accommodate the cutting force requirements of protective films made of different materials, the blade holder 125 is provided with a waist-shaped adjustment hole 1251. The blade holder 125 is fixedly connected to the slitting drive mechanism 124 via bolts and the adjustment hole 1251. By tightening or loosening the bolts at the adjustment hole 1251, the blade holder 125 can slide within a certain range relative to the slitting drive mechanism 124 in a direction approaching or moving away from the slitting back roller 121, thereby adjusting the depth to which the blade of the slitting blade 123 extends into the clearance groove 1211 during slitting, and thus adjusting the cutting force. Understandably, the slitting drive mechanism 124 can be a pneumatic cylinder, an electric cylinder, or a lead screw driven by a motor. (See reference...) Figure 3 and Figure 6 In this embodiment, the slitting drive cylinder is a slide cylinder, and the cutter holder 125 and the slitting pressure plate 122 are fixedly connected to the slide of the slide cylinder.

[0030] Reference Figures 3 to 5 In this embodiment, to prevent dust generated during the slitting of the protective film from falling onto the product below, a dust collection box 126 is provided directly below the slitting blade 123 to catch the dust generated during slitting. It is understood that the number of slitting blades 123 in the slitting mechanism 120 needs to be determined according to the number of products side-by-side, i.e., according to the number of feeding shafts 111 in the feeding assembly 110. In this embodiment, the pressing mechanism 200 simultaneously presses two rolls of products side-by-side, so the slitting mechanism 120 needs to be equipped with one slitting blade 123 to slit the protective film into two segments. In some embodiments, the feeding assembly 110 may include three or more feeding shafts 111 to simultaneously press three or more pieces of product; in this case, the slitting mechanism 120 should have the number of feeding shafts 111 minus one slitting blade 123. It is understood that the distance between adjacent slitting blades 123 should be set according to the width of the product between the slitting blades 123 to ensure that the slitting protective film can completely cover the surface of the corresponding product. In this embodiment, since the widths of the two rolls of products are the same, the slitting blade 123 is positioned at the midpoint of the slitting plate 122.

[0031] In some embodiments, to further improve product production efficiency, the feeding mechanism 100 includes multiple sets of feeding components 110, which are longitudinally distributed on the frame of the feeding mechanism 100. Correspondingly, the unloading mechanism 300 has a number of unloading components 310 corresponding to the number of feeding components 110, and multiple sets of unloading components 310 are longitudinally distributed on the frame of the unloading mechanism 300. The multiple sets of feeding components 110 of the feeding mechanism 100 stack multiple sets of products side by side in a back-to-back manner, and then feed them together into the pressing mechanism 200 for pressing, thereby further improving product processing efficiency.

[0032] Reference Figure 1 , Figure 2 and Figure 8 In this embodiment, both the feeding mechanism 100 and the unloading mechanism 300 include two sets of feeding components 110 and two sets of unloading components 310, respectively. In practice, only one protective film can be provided between the two stacked products. Therefore, the first protective film feeding shaft 112 of the lower feeding component 110 can share a shaft with the adjacent upper second protective film feeding shaft 113 to reduce the number of shafts in the feeding component 110, thereby reducing the size and cost of the equipment. Correspondingly, the first protective film receiving shaft 312 of the lower unloading component 310 can also share a shaft with the adjacent upper second protective film receiving shaft 313 of the upper feeding component 110.

[0033] Reference Figure 2 and Figure 8 In some embodiments, to further prevent the product from being damaged during the pressing process, a protective auxiliary material is also required between the product and the pressing module of the pressing mechanism 200 during pressing. In practice, the protective auxiliary material only needs to be placed between the outermost protective film and the upper or lower pressing module. In this embodiment, since the product groups released by multiple feeding mechanisms are stacked on top of each other before entering the pressing mechanism 200 for pressing, only the uppermost and lowermost feeding components 110 need to contain the rolls of protective auxiliary material. In this embodiment, the feeding component 110 includes a protective auxiliary material feeding shaft 114 for feeding the rolls of protective auxiliary material. Correspondingly, the unloading component 310 includes a protective auxiliary material receiving shaft 314 for rewinding the protective auxiliary material released by the protective auxiliary material feeding shaft 114 into a roll. It is understandable that the winding shaft 311, the first protective film take-up shaft 312, the second protective film take-up shaft 313, and the protective auxiliary material take-up shaft 314 are all drive shafts that can rotate under the drive of a motor.

[0034] Reference Figure 2 and Figure 7In this embodiment, to ensure the pressing quality and avoid wrinkles in the product during pressing, the feeding mechanism 100 includes a pull-back mechanism 130. The pull-back mechanism 130 is disposed on the product's conveyor path and is used to pull the product back, allowing the product within the pressing mechanism 200 to be tensioned. When production is carried out in a back-to-back manner, only one set of pull-back mechanisms 130 can be set. The products released from the two sets of feeding components 110 are first stacked back-to-back before passing through the pull-back mechanism 130 and entering the pressing mechanism 200. (Refer to...) Figure 7 The pull-back mechanism 130 includes a pull-back pressing mechanism 131, a pull-back driving mechanism 132, and a pull-back post-pressing mechanism 133. The pull-back post-pressing mechanism 133 is located on the side of the pull-back pressing mechanism 131 near the pressing mechanism 200. The pull-back pressing mechanism 131 and the pull-back post-pressing mechanism 133 can clamp the product that has passed through. The pull-back pressing mechanism 131 can move along the conveyor path of the product under the drive of the pull-back driving mechanism 132. In this embodiment, the pull-back pressing mechanism 131, the pull-back driving mechanism 132, and the pull-back post-pressing mechanism 133 are all driven by cylinders. When the pull-back driving mechanism 132 drives the pull-back pressing mechanism 131 to pull back, the pull-back pressing mechanism 131 clamps the product that has passed through, while the pull-back post-pressing mechanism 133 releases the product. After the pull-back is completed, the pull-back post-pressing mechanism 133 clamps the released product until the pressing mechanism 200 completes one pressing cycle.

[0035] Reference Figure 8In some embodiments, to ensure that each segment of the continuous product can be pressed once, the feeding mechanism 300 further includes a pulling mechanism 320. The pulling mechanism 320 is disposed on the product's conveyor belt path and is used to pull the product at equal intervals. In this embodiment, the products released by both sets of feeding components 110 are pulled at equal intervals by one set of pulling mechanisms 320. The pulling mechanism 320 includes a pre-pulling pressing mechanism 321, a pulling pressing mechanism 322, a pulling drive mechanism 324, and a post-pulling pressing mechanism 323. The pre-pulling pressing mechanism 321 is disposed close to the pressing mechanism 200, the post-pulling pressing mechanism 323 is disposed away from the pressing mechanism 200, the pulling pressing mechanism 322 is disposed between the pre-pulling pressing mechanism 321 and the post-pulling pressing mechanism 323, and the pulling pressing mechanism 322 is disposed on the pulling drive mechanism 324, and can reciprocate in the product's conveyor belt direction under the drive of the pulling drive mechanism 324. In this embodiment, the material pulling and pressing mechanism 322, the pre-pulling pressing mechanism 321, and the post-pulling pressing mechanism 323 are all driven by cylinders, and the material pulling drive mechanism 324 adopts a linear platform composed of a motor, a lead screw pair, and a guide rail. During material pulling, the pre-pulling pressing mechanism 321 and the post-pulling pressing mechanism 323 release the product, the material pulling and pressing mechanism 322 clamps the product, and pulls the product at equal intervals under the drive of the material pulling drive mechanism 324; after material pulling, the pre-pulling pressing mechanism 321 and the post-pulling pressing mechanism 323 clamp the product, and at the same time, the material pulling and pressing mechanism 322 releases, and the material pulling drive mechanism 324 drives the material pulling and pressing mechanism 322 back to the initial position.

[0036] It is understood that the pressing mechanism 200 should include an upper pressing module, a lower pressing module, and a pressing drive mechanism. Products from multiple sets of feeding assemblies are stacked together and pass between the upper and lower pressing modules. The upper and lower pressing modules, driven by the pressing drive mechanism, press the products onto the passing products, completing the pressing process. In some embodiments, the products typically require heating during the pressing process to improve pressing efficiency and effectiveness; therefore, heating devices such as heating plates are usually provided in the upper and lower pressing modules. A separation mechanism is also typically provided at the outlet of the pressing mechanism 200 to separate the products from the protective film and protective auxiliary materials. It is understood that the specific structure of the pressing mechanism 200 is common knowledge in the art and will not be described in detail here.

[0037] It should be noted that in the description of this utility model, any descriptions of orientation, such as up, down, front, back, left, right, etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and should not be construed as a limitation of this utility model.
