Description

Technical Field

[0001] This utility model relates to the technical field of PP membrane separation and conveying equipment, and in particular to a PP membrane separation and conveying equipment. Background Technology

[0002] In the manufacturing process of printed circuit boards (PCBs), the lamination process is the core step in achieving multi-layer composite structures, and its quality directly determines product performance. However, defects such as delamination and bubbles are prevalent in current production, becoming a pain point for the industry. Delamination manifests as the peeling between the substrate and the prepreg (PP sheet), while bubbles appear as voids formed under high temperature and pressure. These defects can lead to decreased mechanical strength of the PCB, unstable electrical performance, and even cause circuit breaks or short circuits, significantly reducing yield.

[0003] Existing technologies primarily address these issues by optimizing lamination parameters (such as temperature and pressure profiles) and improving materials (such as low-volatile resins), but the effectiveness is limited. The recurring defects not only lead to significant rework and scrap, increasing production costs, but also extend production cycles due to the troubleshooting and repair processes, limiting efficiency improvements and failing to meet the electronics industry's demand for high-reliability, high-volume PCBs. Therefore, a technical solution that can effectively suppress delamination and bubble defects is urgently needed. Utility Model Content

[0004] This utility model discloses a PP membrane separation and conveying device to solve the above-mentioned technical problems existing in related technologies.

[0005] To solve the above problems, the present invention adopts the following technical solution: In a first aspect, this application provides a PP membrane separation and conveying device, including a first conveying mechanism, a second conveying mechanism and a third conveying mechanism arranged sequentially along the PP membrane conveying direction; The first conveying mechanism includes a vertically lifting first conveying platform, which is used to carry multiple layers of stacked PP film and adjust the height of the material layer by lifting the first conveying platform. The second conveying mechanism includes: Second conveyor platform The first material handling unit is vertically mounted on the second conveying platform and is used to pick up a single sheet of PP film from the first conveying platform. The first horizontal drive unit and the first vertical drive unit are both located on the lower side of the second conveying platform; the first horizontal drive unit is used to drive the first material taking unit to reciprocate on the PP film conveying path, and the first vertical drive unit is used to drive the lifting and lowering movement of the first material taking unit. The third conveying mechanism includes: Third conveyor platform The second material handling unit is vertically and vertically mounted on the lower side of the third conveying platform, and is used to grab PP film from the discharge position of the second conveying platform; The second horizontal drive unit and the second vertical drive unit are both located below the third conveying platform; the second horizontal drive unit is used to drive the second material taking unit to reciprocate on the PP film conveying path, and the second vertical drive unit is used to drive the lifting and lowering movement of the second material taking unit.

[0006] The technical solution adopted in this utility model can achieve the following beneficial effects: The PP film separation and conveying equipment provided in this application, through its innovative architecture design for separation and conveying equipment before the lamination process, improves the yield of the printed circuit board (PCB) lamination process, effectively suppresses delamination and bubble defects, reduces rework and scrap, lowers production costs, and improves production efficiency. Specifically: (1) The PP film separation and conveying equipment of this application sets the first horizontal drive unit and the first vertical drive unit of the second conveying mechanism on the lower side of the second conveying platform, and sets the second horizontal drive unit and the second vertical drive unit of the third conveying mechanism on the lower side of the third conveying platform. The second and third conveying platforms form a physical barrier, so that wear debris, dust and other impurities generated during the operation of the drive components are intercepted below the second and third conveying platforms and cannot come into contact with the PP film surface. This design can fundamentally prevent impurities from adhering to the PP film surface and entering the lamination process. This solution directly reduces the generation of defects such as delamination and bubbles in the lamination process by blocking contamination in the pre-process, laying the foundation for improving product yield, reducing production costs and improving production efficiency.

[0007] (2) The lifting and adjusting function of the first conveying platform in this application can dynamically adapt to the material picking height of the multi-layer PP film. Combined with the precise drive of the first picking unit in the second conveying mechanism, it reduces the mechanical contact area during the picking process, reduces the risk of debris generated by friction, and thus reduces the generation of defects such as delamination and bubbles in the lamination process. At the same time, it reduces the risk of wrinkles and scratches on the PP film during the picking process. Meanwhile, the lower-positioned drive units (first horizontal drive unit, first vertical drive unit, second horizontal drive unit and second vertical drive unit) avoid accidental contact between the upper drive components and the PP film in traditional equipment, ensuring that the PP film remains flat and clean during the conveying process. This protection of the material integrity ensures that the PP film entering the lamination process meets the process requirements, reduces rework or scrap due to material damage, and directly reduces production costs.

[0008] (3) The first, second, and third conveying mechanisms are sequentially connected along the material conveying direction. The actions of the first and second picking units are precisely coordinated through the lower-mounted drive units (first horizontal drive unit, first vertical drive unit, second horizontal drive unit, and second vertical drive unit), avoiding the action interference caused by the messy layout of the upper drive components in traditional equipment. At the same time, the drive units are concentrated at the bottom of the equipment, which facilitates maintenance personnel to quickly troubleshoot and reduce downtime. This efficient and stable conveying process shortens the separation and conveying cycle of a single PP film, improves the overall production efficiency, and provides a guarantee for large-scale production.

Detailed Implementation

[0011] The utility model concept of this application is described here: In the manufacturing process of printed circuit boards (PCBs), the lamination process uses high temperature and high pressure to bond the substrate and prepreg (PP film) to form a multi-layer structure. The quality of this process directly affects the mechanical strength and electrical performance of the PCB. In current production, defects such as delamination and bubbles occur frequently. Delamination leads to interlayer peeling, and bubbles form local voids, both of which damage circuit integrity and reduce product yield. Traditional technologies mostly focus on the lamination process itself, addressing defects by optimizing temperature and pressure curves and using materials such as low-volatile resins, but the effects are limited. These solutions fail to consider the potential impact of the pre-conveying process on the PP film 4: wear debris generated by the drive components of the conveying equipment during operation, suspended dust particles in the environment, and friction debris adsorbed by electrostatic attraction between the PP films 4 are easily attached to the film surface. Moreover, these debris attached to the surface of the PP film 4 (including wear debris from the drive components of the conveying equipment, suspended dust particles in the environment, and friction debris adsorbed by electrostatic attraction between the PP films 4) are usually in the micrometer (μm) range, and in most cases cannot be directly observed by the naked eye. It is precisely because of the "invisibility" of these debris that traditional technologies tend to overlook the impact of the pre-conveying process. These impurities, invisible to the naked eye, adhere to the surface of PP film 4 and are then trapped between the substrate and PP film 4 during the high-temperature and high-pressure lamination process. This ultimately leads to visible delamination and bubble defects, becoming a hidden danger affecting PCB yield. The neglect of this contamination path in existing technologies results in repeated defects, increasing rework costs and extending production cycles, making it difficult to meet the electronics industry's demand for high-reliability PCBs.

[0012] Therefore, this application provides a PP membrane separation and conveying device, which is described below in conjunction with... Figures 1-19 The technical solutions disclosed in the embodiments of this application are described in detail.

[0013] This application provides a PP membrane separation and conveying device, including a first conveying mechanism 1, a second conveying mechanism 2 and a third conveying mechanism 3 arranged sequentially along the conveying direction of the PP membrane 4; The first conveying mechanism 1 includes a vertically lifting first conveying platform 101, which is used to carry multiple layers of stacked PP film 4 and adjust the height of the stacked PP film 4 by lifting the first conveying platform 101. The second conveying mechanism 2 includes: Second conveyor platform 201, The first material handling unit 203 is vertically mounted on the second conveying platform 201 and is used to pick up a single PP film 4 from the first conveying platform 101. The first horizontal drive unit and the first vertical drive unit are both located on the lower side of the second conveying platform 201; the first horizontal drive unit is used to drive the first material taking unit 203 to reciprocate on the conveying path of the PP film 4, and the first vertical drive unit is used to drive the lifting and lowering movement of the first material taking unit 203. The third conveying mechanism 3 includes: Third conveyor platform 301, The second material handling unit is vertically mounted on the third conveying platform 301 and is used to grab PP film 4 from the discharge position of the second conveying platform 201. The second horizontal drive unit and the second vertical drive unit are both located below the third conveying platform 301. The second horizontal drive unit is used to drive the second material taking unit to reciprocate on the conveying path of the PP film 4, and the second vertical drive unit is used to drive the lifting and lowering movement of the second material taking unit.

[0014] In some embodiments, the first conveying mechanism 1 further includes a driving component and a first position adjustment component disposed on the first conveying platform 101 for adjusting the position of the PP film 4. It is understood that by providing the driving component and the first position adjustment component in the first conveying mechanism 1, the position of the PP film 4 can be actively controlled, reducing conveying errors caused by positional deviations of the PP film 4.

[0015] In some embodiments, the driving component includes: The drive assembly housing 1012 has a motor mounting cavity formed inside; The drive motor 109 is fixed inside the motor mounting cavity; The drive roller 1010 is connected to the output shaft of the drive motor 109; The driven roller 1011 is mounted on the first conveying platform 101, arranged parallel to the driving roller 1010, and drives the driven roller 1011 to rotate via the driving roller 1010. It can be understood that the drive assembly drives the driving roller 1010 to rotate via the drive motor 109, and the driving roller 1010 then works in conjunction with the driven roller 1011 to form a stable power transmission structure, enabling the conveying of PP film and subsequent position adjustment. The drive assembly housing 1012 provides protection for the internal drive motor 109, while also integrating the layout of various components to make the structure more compact, reducing interference from the external environment on the drive components, and ensuring stable output of conveying power.

[0016] In some embodiments, the first position adjustment components are in four groups, arranged in pairs on both sides of the first conveying platform 101; each group of adjustment components includes: Adjust the housing 108 of the component to form an internal mounting cavity; Adjust cylinder 102 and fix it in the mounting cavity; Adjustment plate 105 is connected to the output shaft of adjustment cylinder 102 via connection plate 106; Adjust slide rail 107; set the movement path along adjustment plate 105; The bottom of the connecting plate 106 is provided with a groove that slides in conjunction with the adjusting slide rail 107. It can be understood that the four sets of first position adjustment components are arranged in pairs on both sides of the first conveying platform 101, allowing simultaneous position adjustment from both sides of the PP film 4. The adjusting cylinder 102 drives the adjusting plate 105, and the smooth sliding is achieved through the cooperation of the adjusting slide rail 107 and the groove. This allows for flexible adaptation to PP films of different widths, quick correction of lateral offset, and ensures accurate positioning of the PP film 4, improving the precision and efficiency of the adjustment. After the position of the stacked PP films 4 is adjusted, subsequent separation and conveying processes can proceed.

[0017] In some embodiments, the first conveying platform 101 adopts a lifting trolley structure, including a vertically liftable platform; the drive assembly and adjustment assembly are both mounted on the platform. The first conveying platform 101, with its lifting trolley structure and vertically liftable platform, integrates the drive assembly and adjustment assembly, ensuring that the stacked PP films 4 are at the same horizontal level through height adjustment. This design eliminates grasping obstacles caused by inconsistent heights, making the grasping action smoother, reducing potential positioning deviations or jamming problems during grasping, and improving the reliability and efficiency of the grasping operation.

[0018] In some embodiments, the first conveying mechanism 1 further includes a conveying slide rail 104 and a conveying cylinder 103; The conveying slide rail 104 is arranged in a horizontal direction and is provided with a guide groove. The bottom of the lifting platform is provided with a pulley group that slides in cooperation with the guide groove of the conveying slide rail 104; The piston rod of the conveying cylinder 103 is connected to the bottom of the lifting platform, and is used to push the lifting platform to move along the conveying slide rail 104. The first conveying mechanism 1, through the horizontally arranged conveying slide rail 104 and guide groove, in conjunction with the pulley group at the bottom of the lifting platform, realizes the smooth horizontal movement of the lifting platform; the conveying cylinder 103 provides power, making the horizontal displacement adjustment of the lifting platform more precise and controllable. This structural design allows the conveying mechanism to be flexibly moved away when impurities need to be cleaned, avoiding space occupation and obstruction for cleaning operations, facilitating the rapid completion of impurity cleaning work, and ensuring the continuous and stable operation of the equipment.

[0019] In some embodiments, the second conveying mechanism 2 includes a first housing 202 disposed on the lower side of the second conveying platform 201, and a first ash collection assembly is provided at the bottom of the first housing 202; the first ash collection assembly includes a first ash collection hopper 206 formed at the bottom of the first housing 202 and a first ash discharge pipe 207, the first ash discharge pipe 207 being connected to the discharge port of the first ash collection hopper 206 and extending to the external environment; The third conveying mechanism 3 includes a second housing 302 disposed below the third conveying platform 301. A second dust collection assembly is located at the bottom of the second housing 302. The second dust collection assembly includes a second dust collection hopper 306 and a second dust discharge pipe 307 formed at the bottom of the second housing 302. The second dust discharge pipe 307 is connected to the outlet of the first dust collection hopper 206 and extends to the external environment. It is understood that the second conveying mechanism 2 and the third conveying mechanism 3, through the first housing 202, the second housing 302, and the corresponding first and second dust collection assemblies, respectively, can centrally collect debris and dust generated by the lower drive unit and discharge them through the first and second dust discharge pipes 207 and 307. This prevents dust from accumulating inside the equipment and contaminating the PP film, maintains a clean conveying environment, reduces problems such as bubbles and delamination caused by impurities entering the lamination process, and helps improve the lamination yield.

[0020] In some embodiments, the PP membrane separation and conveying equipment further includes an auxiliary separation mechanism, which comprises: The first auxiliary separation component 5 is vertically and flexibly disposed on one side of the material picking position of the second conveying platform 201, and is configured to selectively press or release the lower PP film 4 layers (excluding the top layer) of the stacked PP film 4 through lifting motion. The second auxiliary separation component 6 is vertically and vertically positioned on the other side away from the material pick-up position of the second conveying platform 201. It is configured to selectively press or release the lower PP film 4 layers (excluding the top layer) of the stacked PP film 4 through lifting and lowering motion. The first auxiliary separation component 5 and the second auxiliary separation component 6 alternately perform the pressing action, so that when one set of auxiliary separation components presses the lower PP film 4 layer, the other set of auxiliary separation components releases the PP film 4 layer, thereby enabling the first material handling unit 203 to grab the top single PP film 4 that has not been pressed. Understandably, when multiple PP films 4 are stacked, adjacent PP films 4 are staggered. For example, when the first auxiliary separation component 5 presses the PP film 4 layers together (while the second auxiliary separation component 6 is in the state of releasing the PP film 4 layers), due to the staggered placement of the adjacent PP films 4, the top PP film 4 of the stacked PP films 4 is not pressed. At this time, the top PP film 4 can be picked up by the first material handling unit 203. When it is necessary to pick up the next PP film 4, the second auxiliary separation component 6 presses the PP film 4 layers together (while the first auxiliary separation component 5 is in the state of releasing the PP film 4 layers). Similarly, the top PP film 4 of the stacked PP films 4 is not pressed. At this time, the top PP film 4 can be picked up by the first material handling unit 203. This process of separating and conveying PP films 4 is repeated sequentially. This auxiliary separation mechanism, through the alternating pressing design of the first auxiliary separation component 5 and the second auxiliary separation component 6, can accurately achieve the separation effect of "releasing only the top PP film and fixing the lower PP film layers". On the one hand, it completely avoids the problem of simultaneous gripping and friction of multiple PP films caused by the inability to accurately separate them during the traditional material handling process, reducing debris and impurities generated by friction, and reducing delamination and bubble defects caused by impurities in subsequent lamination processes from the source. On the other hand, the alternating pressing action logic can prevent the lower PP film layer from shifting or wrinkling during material handling, ensuring that each PP film entering the conveying process remains flat, reducing rework and scrap due to material damage. At the same time, this orderly separation method can also work in conjunction with the action of the first material handling unit 203 to improve material handling efficiency and accuracy, avoid conveying interruptions caused by separation errors, further ensure the stability of the overall production process, and lay the foundation for a high yield rate in the lamination process.

[0021] In some embodiments, the first auxiliary separation component 5 includes: The first pressing component is configured to directly contact and selectively press the PP film 4; The third horizontal drive unit is connected to the first pressing assembly and is configured to drive the first pressing assembly to reciprocate along the direction of the PP film 4 conveying path. The third vertical drive unit, connected to the first clamping assembly, is configured to drive the first clamping assembly to perform lifting and lowering movements to perform clamping or releasing actions. It is understood that the third horizontal drive unit of the first auxiliary separation assembly 5 can drive the first clamping assembly to adapt to the clamping requirements of PP films of different sizes, enhancing the equipment's compatibility with diverse materials. Simultaneously, the third vertical drive unit ensures precise execution of the clamping action, reliably fixing the PP film while avoiding excessive pressure that could damage the material, thus improving the equipment's applicability and safety. Furthermore, by ensuring stable clamping of PP films of different sizes, it avoids instability caused by size mismatch, reduces the shaking and friction of the PP film during material handling, thereby reducing the possibility of impurities adhering to the film surface, providing clean and flat material for the lamination process, and helping to improve lamination yield.

[0022] In some embodiments, the first pressing assembly includes a first pressing plate 501; the first pressing plate 501 is driven to move up and down by a third vertical drive unit 503, and the up and down movement of the first pressing plate 501 realizes the pressing and releasing of the PP film 4; the first pressing plate 501 is moved forward and backward by a third horizontal drive unit 502; the third horizontal drive unit 502 and the third vertical drive unit 503 can be electric push rods, cylinders, motors, etc.

[0023] In some embodiments, the second conveying mechanism 2 further includes a first frame 2011 disposed within the first housing 202, and the first conveying platform 201 disposed on the top of the first frame 2011; a first conveying path through groove 2012 is provided on the first conveying platform 201 along the conveying path of the first material handling unit 203; and a pressing path through groove 2013 is provided on the first conveying platform 201 along the moving path of the first pressing assembly.

[0024] In some embodiments, the second conveying mechanism 2 further includes a second position adjustment assembly, which includes an auxiliary second clamping plate 2016, a first clamping plate 2014, and a first movable clamping bar 2015. The auxiliary second clamping plate 2016 is provided with a slide rail 2017 extending in a horizontal direction and is equipped with a horizontal drive member 2018. The first clamping plate 2014 is connected to the output end of the horizontal drive member 2018 and slides with the slide rail 2017 through a groove provided at its bottom, so that the first clamping plate 2014 is driven by the horizontal drive member 2018 to move horizontally along the slide rail 2017. The first movable clamping bar 2015 is installed on the first clamping plate 2014 through a vertical drive member 2019. The vertical drive member 2019 drives the first movable clamping bar 2015 to move up and down relative to the first clamping plate 2014, so that the first movable clamping bar 2015 and the first clamping plate 2014 work together to complete the clamping or releasing action of the PP film 4.

[0025] In some embodiments, the third conveying mechanism 3 further includes a second frame 3011 disposed inside the second housing 302, and a second conveying platform 301 disposed on top of the second frame 3011. A second conveying path channel 3012 is provided on the second conveying platform 301 along the conveying path of the second material handling unit.

[0026] In some embodiments, the second auxiliary separation component 6 includes: The second pressing component is configured to directly contact and selectively press the PP film 4; The fourth horizontal drive unit is connected to the second pressing assembly and is configured to drive the second pressing assembly to reciprocate along a direction perpendicular to the conveying path of the PP film 4; A fourth vertical drive unit, connected to the second pressing assembly, is configured to drive the second pressing assembly to perform lifting and lowering movements to perform pressing or releasing actions. It is understood that the fourth horizontal drive unit of the second auxiliary separation assembly 6 enables the second pressing assembly to adjust its position along the conveying direction, cooperating with the first auxiliary separation assembly 5 to press PP films 4 of different sizes. The fourth vertical drive unit ensures timely switching between pressing and releasing actions, coordinating with the actions of the material handling unit to improve the efficiency of separation and conveying. Furthermore, the second auxiliary separation assembly 6 and the first auxiliary separation assembly 5 in this application cooperate to achieve more precise alternating pressing, reducing displacement and friction of the PP film 4 layers, lowering the risk of debris contamination, and ensuring the flatness of each separated PP film 4, which is beneficial for improving lamination quality.

[0027] In some embodiments, the second clamping assembly includes a second clamping plate 601; the fourth vertical drive unit includes a fourth vertical drive cylinder 603; the second clamping plate 601 is driven to move up and down by the fourth vertical drive cylinder 603. The fourth horizontal drive unit includes a fourth horizontal drive motor 602, and the second clamping plate 601 is driven to move horizontally by the fourth horizontal drive motor 602.

[0028] In some embodiments, the second auxiliary separation assembly 6 further includes a second shovel 605 and a fifth vertical drive cylinder 604 for driving the second shovel 605 to perform lifting and lowering actions. The second shovel 605 is used to assist in separating the PP film 4 during separation.

[0029] In some embodiments, the PP film separation and conveying equipment further includes an antistatic mechanism, which includes: The first static elimination component is disposed on the first material handling unit 203 and is configured to eliminate static electricity between the films by blowing ionized airflow onto the PP film 4. The second antistatic component, integrated on the second pressing component, is configured to eliminate static electricity between the membranes by blowing an ionized airflow onto the pressed PP membrane 4. In this process, the first and second antistatic components work synergistically to prevent electrostatic adsorption and adhesion between layers of PP film 4. The first and second antistatic components eliminate static electricity between the films by blowing ionized airflow onto the PP material. Their synergistic action breaks up the adhesion caused by static electricity, making it easier for the first feeding unit 203 to separate individual PP films 4, ensuring a smooth separation process and preventing abnormal feeding due to adhesion. After static electricity is eliminated, the PP films 4 will not adhere due to electrostatic adsorption, avoiding friction and debris generation caused by multiple films being lifted simultaneously during feeding, thus reducing film surface contamination. Simultaneously, smooth separation of individual films allows them to remain flat for subsequent processes, reducing the risk of bubbles and delamination caused by film wrinkles or overlaps during lamination, which is beneficial for improving lamination yield. Furthermore, after static electricity is eliminated, the possibility of dust adsorbed onto the film surface due to static electricity is reduced; whether visible or invisible dust, its adhesion is significantly reduced, thus providing a cleaner material basis for the lamination process.

[0030] In some embodiments, the first static eliminator includes: The first ionization nozzle 7 is configured to generate positive and negative ions and blow them onto the surface of the PP film 4 via airflow. The first high-voltage power supply is electrically connected to the first ionization nozzle 7 through a high-temperature resistant insulated wire to provide the high voltage required for ionization. The output voltage range of the first high-voltage power supply is 5kV-15kV, which is compatible with the ionization requirements of the first ionization nozzle 7. The first air supply system includes a compressed air filter, a pressure regulating valve and a flow meter, which are used to provide a clean and stable airflow to the first ionized air nozzle 7; The first mounting bracket is used to install the first ionizing gas nozzle 7 on the first material handling unit 203. It is understood that, firstly, the positive and negative ions generated by the first ionizing gas nozzle 7 can quickly neutralize the static electricity on the surface of the PP film 4, preventing the static electricity from attracting dust, debris, and other impurities from the air. This directly blocks the problem of "impurities causing lamination defects," ensuring that the surface cleanliness of the PP film 4 meets the requirements of the lamination process. Secondly, after static electricity is eliminated, it can prevent difficulties in material handling and multiple film grabbing caused by static adhesion between PP films 4, reducing mechanical friction and film surface scratches during the material handling process, and protecting the physical integrity of the PP film 4. Furthermore, the first air supply system, through filtration, pressure regulation, and flow control design, can provide clean and stable airflow to the ionizing gas nozzle, ensuring the stability of the static electricity removal effect and preventing the introduction of new contamination due to impurities in the airflow or pressure fluctuations, further strengthening the protection of the cleanliness of the PP film 4 and indirectly reducing the defect risk of the lamination process.

[0031] In some embodiments, the second static eliminator includes: The second ionization nozzle 8 is configured to generate positive and negative ions and blow them onto the surface of the PP film 4 via airflow. The second high-voltage power supply is electrically connected to the second ionization nozzle 8 through a high-temperature resistant insulated wire. It is used to provide the high voltage required for ionization. The output voltage range of the second high-voltage power supply is 5kV-15kV, which is compatible with the ionization requirements of the second ionization nozzle 8. The second air supply system includes a compressed air filter, a pressure regulating valve and a flow meter, which is used to provide a clean and stable airflow to the second ionized air nozzle 8. The second mounting bracket is used to mount the second ionizing air nozzle 8 onto the second pressing assembly. It is understood that although the second antistatic assembly is structurally similar to the first antistatic assembly, its layout design on the second pressing assembly creates a "dual antistatic guarantee." The second antistatic assembly blows ionized airflow onto the upper surface of the PP film 4 to eliminate static electricity. When the first picking unit 203 picks up material, after the top layer of PP film 4 is grasped and detached from the lower layer PP film 4, the first antistatic assembly blows ionized airflow onto the underside of the PP film 4 grasped by the first picking unit 203 to eliminate static electricity between the grasped PP film 4 and the lower layer PP film 4. Then, the first horizontal drive unit drives the first picking unit 203 to transport the PP film 4. The first and second antistatic assemblies can operate continuously or only when ionized airflow is required.

[0032] In some embodiments, the first conveying platform 101, the second conveying platform 201 and the third conveying platform 301 are respectively provided with a first detection sensor, a second detection sensor and a third detection sensor for detecting the height and position of the PP film 4. The first detection sensor, the second detection sensor and the third detection sensor are all used to detect the position and stacking height of the PP film 4, and a suitable detection sensor can be selected. Understandably, firstly, for the first conveying platform 101, the stacking height detected by the first detection sensor can directly guide the lifting and lowering adjustment of the first conveying platform 101, ensuring that the material picking height always matches the action requirements of the first material picking unit 203, reducing unnecessary contact between the material picking unit and the PP film 4, and reducing the risk of friction-induced debris; secondly, for the second conveying platform 201 and the third conveying platform 301, position detection can promptly detect PP film 4 conveying deviation problems, avoiding collisions, wrinkles or scratches caused by material deviation, and ensuring the integrity of the PP film 4; in addition, real-time height and position monitoring can quickly identify abnormal states (such as excessive stacking or missing materials), facilitating timely equipment adjustment or issuing warnings, avoiding prolonged downtime caused by the expansion of abnormalities, improving overall conveying efficiency, and ensuring that the PP film 4 entering the lamination process meets the process requirements in terms of position and shape, indirectly reducing lamination defects.

[0033] In some embodiments, the first picking unit 203, the second picking unit, and the third picking unit all employ a vacuum suction cup 2031 or a mechanical gripper. It is understood that the vacuum suction cup 2031 uses negative pressure to adsorb the PP film 4, avoiding debris contamination of the film surface during gripping; the controllable force of the mechanical gripper reduces scratches on the film surface and prevents impurities from adsorbing at damaged areas. Both methods maintain the cleanliness and integrity of the PP film 4, reducing bubbles and delamination problems caused by film surface contamination or damage during lamination, thus improving lamination yield.

[0034] In some embodiments, the first horizontal drive unit, the second horizontal drive unit, the third horizontal drive unit, the third horizontal drive unit 502 and the fourth horizontal drive unit, and the horizontal drive component are all linear modules, synchronous belt drive mechanisms, cylinders or electric push rods; of course, other drive mechanisms can also be used as long as they can achieve horizontal drive.

[0035] In some embodiments, the first vertical drive unit, the second vertical drive unit, the third vertical drive unit 503, the fourth vertical drive unit, and the vertical drive component are cylinders or electric push rods; of course, other drive mechanisms can also be used as long as they can achieve vertical drive.

[0036] In some embodiments, the first material handling unit 203 is in multiple groups, and each group of the first material handling unit 203 includes a suction cup 2031 and a first shovel plate 2032. The first shovel plate 2032 is used to assist in the separation of the PP film 4 during the separation process. Its position needs to be appropriate for assisting in the separation of the PP film 4. Multiple groups of the first material handling unit 203 (suction cup 2031 and first shovel plate 2032) are all mounted by the first mounting frame 208. The second conveying mechanism 2 also includes a first horizontal slide rail 209 and a first vertical slide rail 2010 arranged along the conveying path of the PP film 4. The first horizontal drive unit includes a first horizontal drive motor 204, and the first vertical drive unit includes a first vertical drive cylinder 205. The first mounting frame 208 is driven by the first horizontal drive motor 204 to reciprocate along the conveying path, and the first mounting frame 208 is driven by the first vertical drive cylinder 205 to perform lifting and lowering actions, so as to realize the material handling and conveying of the first material handling unit 203.

[0037] In some embodiments, the second material handling unit is in multiple groups, and each group of the second material handling unit includes a second clamping plate 303 and a second movable clamping bar 308; the multiple groups of the second material handling unit (the second clamping plate 303 and the second movable clamping bar 308) are all installed through the second mounting frame 309; the second horizontal drive unit 304 drives the second mounting frame 309 to move horizontally, thereby driving the second material handling unit to move horizontally; the third conveying mechanism 3 also includes a second horizontal slide rail 3010 arranged along the conveying path of the PP film 4; when the second mounting frame 309 moves horizontally, it moves along the second horizontal slide rail 3010.

[0038] The second vertical drive unit includes a second vertical drive component 3013 for driving the second clamping plate 303 to move up and down and a third vertical drive component 305 for driving the second moving clamping bar 308 to move up and down. The combined action of the second vertical drive component 3013 and the third vertical drive component 305 is to control the lifting and lowering of the second material picking unit and to realize the gripping and releasing of the PP film 4, thereby realizing the material picking and conveying of the second material picking unit.

[0039] In some embodiments, the PP film separation and conveying equipment further includes a control system, which is electrically connected to the first conveying mechanism 1, the second conveying mechanism 2, the third conveying mechanism 3, the auxiliary separation mechanism, the static electricity removal mechanism, the first detection sensor, the second detection sensor, and the third detection sensor, respectively. It is understood that the control system is electrically connected to each mechanism and sensor of the equipment. By coordinating the actions of each part, debris contamination caused by mechanical interference can be avoided; at the same time, the static electricity removal and separation processes can be precisely controlled to ensure that the PP film 4 is clean and that single-sheet separation is accurate. This coordinated control reduces the risk of contamination, stabilizes the state of the PP film 4 entering lamination, effectively reduces defects such as delamination and bubbles, and improves the lamination yield.

[0040] The working process of the PP membrane separation and conveying equipment in this application includes the following steps: S1. Equipment initialization, initial loading, and height adjustment: After the equipment is started, the control system establishes electrical connections with the first conveying mechanism 1, the second conveying mechanism 2, the third conveying mechanism 3, the auxiliary separation mechanism, the static elimination mechanism, and each detection sensor, completing the initial state self-check of each mechanism (such as whether the drive unit has reset, whether the static elimination component is properly ventilated and powered, etc.). Subsequently, the operator places the multi-layered stacked PP film (staggered layers) onto the platform of the first conveying platform 101 (lifting trolley structure) of the first conveying mechanism 1. The first detection sensor immediately activates, detecting the initial stacking height and edge position of the PP film 4, and feeding the data back to the control system. Based on the stacking height data fed back by the first detection sensor, the control system controls the first conveying platform 101 to lift and lower via the lifting trolley, adjusting the stacking height of the PP film 4 to match the picking position of the first picking unit 203.

[0041] S2.PP film 4 position adjustment: If the first detection sensor detects a slight positional shift in the PP film, the drive assembly on the first conveying platform 101 is activated in advance: the drive motor 109 drives the active roller 1010 to rotate, and the active roller 1010 works in conjunction with the driven roller 1011 to slightly move the PP film on the platform, initially correcting the positional deviation. After the drive assembly completes the initial positional correction, the four adjustment assemblies are activated. The adjustment assemblies move in pairs from both sides of the first conveying platform 101, with the adjustment cylinder 102 driving the adjustment plate 105. With the help of the sliding cooperation between the bottom groove of the connecting plate 106 and the adjustment slide rail 107, the plate smoothly moves towards the edge of the PP film. Through the synchronous pushing of the adjustment plates 105 on both sides, the lateral shift of the PP film is precisely corrected, ensuring that the PP film is completely aligned with the preset conveying path.

[0042] S3. Auxiliary separation mechanism: alternating clamping and static electricity removal pretreatment. The control system controls the first auxiliary separation component 5 and the second auxiliary separation component 6 to alternately perform the clamping action. In the initial stage, the third vertical drive unit 503 of the first auxiliary separation component 5 drives the first clamping component (first clamping plate 501) to descend, clamping the lower PP film layer (excluding the top layer) in the stacked PP film; at the same time, the second auxiliary separation component 6 remains in the released state. During this process, the second antistatic component (integrated into the second clamping component) starts blowing clean ionized airflow onto the upper surface of the PP film to neutralize the static electricity on the PP film surface, prevent film adhesion caused by electrostatic adsorption, and prepare for subsequent material removal; the second antistatic component continues to blow clean ionized airflow thereafter.

[0043] S4. The first material handling unit 203 picks up the top layer of PP film: The first material handling unit 203 (multiple sets of vacuum suction cups 2031 or mechanical grippers) descends under the drive of the first vertical drive cylinder 205 (first vertical drive unit). When the suction cups 2031 contact the top PP film, negative pressure adsorption is initiated (or the mechanical grippers initiate controllable force clamping). Simultaneously, the first antistatic component on the first material handling unit 203 is activated, and the first ionization nozzle 7 blows ionized airflow towards the underside of the adsorbed top PP film to eliminate static electricity between the top and bottom PP films, preventing multiple films from being gripped due to static adhesion during material handling. After adsorption stabilizes, the first vertical drive cylinder 205 drives the first material handling unit 203 to rise, detaching it from the bottom PP film; the first antistatic component then continuously blows clean ionized airflow.

[0044] S5: Top PP film is conveyed to the second conveying platform 201. After the first material handling unit 203 rises to a safe height, the first horizontal drive motor 204 (first horizontal drive unit) drives the first mounting frame 208 (equipped with a suction cup 2031 and a first shovel plate 2032) to move along the first horizontal slide rail 209, thereby conveying the top layer of PP film to the discharge position of the second conveying platform 201. During this process, the first dust collection component of the first housing 202 on the lower side of the second conveying mechanism 2 works simultaneously. The debris and dust generated by the drive unit on the lower side of the platform fall into the first dust collection hopper 206, and are then discharged to the external environment through the first dust discharge pipe 207, preventing dust from spreading and contaminating the PP film during conveying.

[0045] S6: Second transmission platform 201 receiving and transition detection After the first material handling unit 203 conveys the top layer PP film to the discharge position of the second conveying platform 201, the first vertical drive cylinder 205 drives it to descend, releasing the PP film 4 onto the surface of the second conveying platform 201. The second detection sensor immediately detects the position of the PP film on the second conveying platform 201; if the position is not suitable for the next conveying step, the position can be adjusted by the second position adjustment component.

[0046] S7: Auxiliary separation mechanism switching and subsequent PP membrane separation When the first picking unit 203 feeds PP film to the second conveying platform 201, the control system controls the auxiliary separation mechanism to switch its working state: the fourth vertical drive cylinder 603 (fourth vertical drive unit) of the second auxiliary separation component 6 drives the second pressing component (second pressing plate 601) to descend, pressing the lower PP film layer in the remaining stacked PP film except for the new top layer. At the same time, the third vertical drive cylinder 503 of the first auxiliary separation component 5 drives the first pressing component to rise and release the PP film layer. In addition, the first detection sensor detects the stacking height of the remaining PP film in real time. If the height decreases, the control system controls the first conveying platform 101 to rise and fall again, adjusting the new top layer PP film 4 to the preset picking height, so that after the first picking unit 203 returns, steps S3-S5 are repeated to continuously separate single PP films.

[0047] S8: The second material handling unit grabs and conveys the material to the third conveying platform 301. After the PP film on the second conveying platform 201 is ready, the second material handling unit (multiple sets including the second clamping plate 303 and the second moving clamping bar 308) of the third conveying mechanism 3 descends under the drive of the second vertical drive unit, and clamps the PP film 4 through the cooperation of the second clamping plate 303 and the second moving clamping bar 308. Subsequently, the second horizontal drive unit 304 drives the second mounting frame 309 to move along the second horizontal slide rail 3010, driving the PP film 4 to be conveyed to the third conveying platform 301. During this process, the second dust collection component of the second housing 302 on the lower side of the third conveying mechanism 3 is activated, collecting the dust accumulated on the lower side of the platform and discharging it through the second dust discharge pipe 307, keeping the conveying environment clean.

[0048] S9: Third conveyor platform 301 transitions and conveys materials to the lamination process. After the second material handling unit conveys the PP film 4 to the third conveying platform 301, the second vertical drive unit drives it to release the PP film 4. The third detection sensor detects the position of the PP film 4, completing a single separation and conveying process of the PP film 4. If there is still PP film 4 remaining on the first conveying platform 101, the equipment cyclically executes steps S3-S8 until all PP film 4 has been separated and conveyed. If it is necessary to clean the equipment of impurities, the conveying cylinder 103 of the first conveying mechanism 1 can be controlled to push the lifting trolley along the conveying slide rail 104 to move it away and clean the impurities. After cleaning, the equipment is reset and continues to work.
