[0002] In automated production lines, the receiving machine, as a key piece of equipment for continuous material conveying, is widely used in fields such as electronic component processing. Its core function is to quickly and accurately connect a new material strip to the old one when a roll of material (used material strip) is about to run out, thereby preventing production line interruptions due to material changes and ensuring stable production efficiency. The film wrapping module, as an important component of the receiving machine, primarily functions to wrap the new and old material strips with film to connect them.

[0003] The film feeding assembly is a component that provides a stable and continuous supply of film for the film wrapping module. Currently available film feeding assemblies generally suffer from high structural complexity and large dimensions. This design not only increases manufacturing costs but also requires significant installation space, making installation, debugging, and maintenance extremely inconvenient and unsuitable for smaller equipment. Therefore, to address the issues of complex structure, high cost, inconvenient installation, and large space requirements of existing film feeding assemblies, there is an urgent need to propose a simplified film feeding assembly to meet the needs of receiving machines in practical production applications and enhance their market competitiveness.

[0029] This utility model proposes a film feeding assembly.

[0030] Please see Figures 1 to 5In one embodiment of this utility model, the film feeding assembly is used in a receiving machine to provide film for the film wrapping module. The film is used to connect the old and new film strips together. The film feeding assembly includes a mounting plate 10, a film driving roller 20, a film mounting roller 30, a first film transition roller 40, a peeling blade assembly 50, a first drive motor 60, and a second drive motor 70. The film driving roller 20 is rotatably connected to the mounting plate 10 and is used to receive the bottom film of the film. The film mounting roller 30 is rotatably connected to the mounting plate 10 and is used to mount the film. The first film transition roller 40 is rotatably connected to the mounting plate 10. The peeling blade assembly 50 is movably mounted on the mounting plate 10 and is used to separate the bottom film of the film from the upper film. The first drive motor 60 is connected to the mounting plate 10 and is drively connected to the peeling blade assembly 50; the second drive motor 70 is connected to the mounting plate 10, and the rotating shaft of the second drive motor 70 is connected to the film driving roller 20. The film drive roller 20, film mounting roller 30, first film transition roller 40, first drive motor 60, and second drive motor 70 are distributed on opposite sides of the mounting plate 10. The film is drawn out from the film mounting roller 30 and passes through the first film transition roller 40, the peeling knife assembly 50, and the film drive roller 20 in sequence, and the bottom film of the film is collected on the film drive roller 20.

[0031] Specifically, the mounting plate 10 serves as the foundational support component of the entire film supply assembly, providing the mounting reference and support carrier for all other functional components. It is the core foundation for the assembly's structural integration. The film installation roller 30 is rotatably connected to the mounting plate 10, serving as the initial installation carrier for the film, used to load the roll of film and provide the film source for the assembly. The first film transition roller 40 is also rotatably connected to the mounting plate 10, its main function being to guide the film transmission direction and assist the film in a smooth transition between different functional components. The film drive roller 20 is rotatably connected to the mounting plate 10, its function being to collect the bottom film after film separation, and simultaneously providing power assistance for film transmission through its own rotation. The peeling blade assembly 50 is movably connected to the mounting plate 10, possessing movable structural attributes. Its function is to achieve layered processing of the film, precisely separating the bottom film from the upper functional film (such as the adhesive film), providing the required upper film for the subsequent film wrapping module. The first drive motor 60 is fixedly connected to the mounting plate 10 and forms a transmission connection with the peeling blade assembly 50, providing power for the movement of the peeling blade assembly 50 (such as position adjustment and separation action drive). The second drive motor 70 is also connected to the mounting plate 10, and its rotating shaft is directly fixedly connected to the film drive roller 20. It directly drives the film drive roller 20 to rotate through its own rotation, providing the core power for bottom film storage and overall film transfer. The film drive roller 20, film mounting roller 30, first film transition roller 40, first drive motor 60, and second drive motor 70 are distributed on opposite sides of the mounting plate 10, forming a partitioned layout of functional and power components.

[0032] This embodiment features an integrated design centered on the mounting plate 10, with separate side layouts for functional and power components. This results in a more regular component structure, reduces spatial interference between components, simplifies the overall structure, reduces the number of parts and assembly difficulty, and minimizes size limitations on installation space. Simultaneously, the separate layout clearly defines the boundary between the "film processing area" and the "power area," significantly reducing the probability of workers coming into contact with power components when changing film (operating the film mounting roller 30), cleaning the bottom film (operating the film drive roller 20), or adjusting the peeling blade assembly 50, thus reducing operational interference. Furthermore, since the second drive motor 70 has no intermediate transmission components and the working area is free of easily damaged transmission parts such as belts, the impact of transmission component failures on operation is reduced. The second drive motor 70 directly drives the film drive roller 20, providing direct and stable power transmission. This allows for precise control of the film drive roller 20's rotation speed, thereby controlling the film transmission speed and preventing issues with excessively fast or slow film transmission.

[0033] Furthermore, the film feeding assembly also includes a film tensioning block 80, which is located between the first film transition roller 40 and the peeling blade assembly 50.

[0034] Specifically, in this embodiment, the film tensioning block 80 is fixedly installed on the mounting plate 10 and located between the first film transition roller 40 and the peeling assembly 50. The position of the film tensioning block 80 is matched to the film conveying path, with one end corresponding to the discharge end of the first film transition roller 40 and the other end corresponding to the feed end of the peeling assembly 50. This ensures that after the film is drawn out from the first film transition roller 40, it can enter the film tensioning block 80 and then smoothly enter the peeling assembly 50, forming a continuous conveying path of "first film transition roller 40 → film tensioning block 80 → peeling assembly 50", avoiding the film from shifting or being suspended in this section of the path.

[0035] Because the distance between the first film transition roller 40 and the peeling blade assembly 50 is relatively long, the film is prone to sagging, loosening, and wrinkling when transported without support. The film tensioning block 80 directly solves this structural defect by providing stable support and tension adjustment in this long path. Whether it is sagging caused by gravity or loosening caused by fluctuations in the transmission speed, the tensioning block can correct it in real time, ensuring that the film remains flat throughout the long-distance transmission section, thus eliminating the transmission hazards caused by the long distance from the root.

[0036] Furthermore, the mounting plate 10 is vertically arranged, with the first film transition roller 40 and the peeling blade assembly 50 positioned near the upper end of the mounting plate 10; the film mounting roller 30 and the film driving roller 20 positioned near the lower end of the mounting plate 10; and the film mounting roller 30 positioned near the first film transition roller 40, and the film driving roller 20 positioned near the peeling blade assembly 50.

[0037] Specifically, the mounting plate 10 adopts a vertical installation method, meaning that the mounting plate 10 is fixed in a position perpendicular to the horizontal plane, breaking the traditional layout mode of horizontal mounting plates 10. This provides basic support for the vertical and horizontal partitioning of subsequent components, while effectively utilizing vertical space and reducing the horizontal area occupied by components. The first film transition roller 40 and the peeling blade assembly 50 are concentrated near the upper end of the mounting plate 10, forming the "upper working sub-area" in the upper vertical direction of the mounting plate 10, mainly responsible for guiding and separating the film. The film mounting roller 30 and the film driving roller 20 are concentrated near the lower end of the mounting plate 10, forming the "lower working sub-area" in the lower vertical direction of the mounting plate 10, mainly responsible for storing the film and collecting the bottom film. The film mounting roller 30 is positioned close to the first film transition roller 40 (upper part), and the film driving roller 20 is positioned close to the peeling blade assembly 50 (upper part), so that the lower part and the corresponding upper functional part form an approximately "upper-lower correspondence" layout relationship in the vertical direction.

[0038] The vertically arranged mounting plate 10, combined with the upper and lower component partitions, concentrates the originally horizontally dispersed components into a vertical space, significantly reducing the horizontal area occupied by the components. This is particularly suitable for scenarios with dense equipment and limited space in automated production lines. The film mounting roller 30 is close to the first film transition roller 40, making the transmission path of the film from the storage end to the guide end shorter and the transmission direction closer to vertical upward, reducing the sagging and uneven tension of the film caused by gravity due to long-distance inclined transmission. The film drive roller 20 is close to the peeling blade assembly 50, allowing the separated bottom film to enter the storage end through a short, almost vertical downward path, avoiding entanglement of the bottom film with other components during transmission, reducing power loss during bottom film storage, improving the neatness of bottom film storage, and further ensuring the overall stability of film transmission. The film mounting roller 30 is located at the lower end of the mounting plate 10, allowing operators to change the roll of film without climbing, reducing operational difficulty and safety risks.

[0039] Furthermore, the peeling assembly 50 includes a peeling block 51, a transmission assembly 52, and a movable roller 53. The first drive motor 60 is connected to the peeling block 51 and the movable roller 53 via the transmission assembly 52. ​​The transmission assembly 52 is used to drive the peeling block 51 and the movable roller 53 to move synchronously toward the first film transition roller 40. The movable roller 53 is located below the peeling block 51 and at the rear end of the peeling block 51. The movable roller 53 and the film drive roller 20 are located on the same side of the mounting plate 10.

[0040] Specifically, in this embodiment, the first drive motor 60 is the power source, and its output shaft is directly or indirectly connected to the input end of the transmission component 52, transmitting rotational power to the transmission component 52. The transmission component 52 distributes power synchronously to the peeling block 51 and the movable roller 53 through its own structure, driving them to move synchronously toward and away from the first material film transition roller 40. The peeling block 51 and the movable roller 53 work together to separate the bottom film and the top film. Driven by the transmission component 52, they can extend to the side away from the first material film transition roller 40, and can also retract (reset state) after completing the peeling assistance. The telescopic movement adapts to the overall operation of the device. The separated top film is used to bond the new and old material strips together. The suction head moves above the material film and sucks up the peeled top film through negative pressure adsorption, which will be used for subsequent bonding operations of the old and new material strips.

[0041] The specific process is described below:

[0042] Initial preparation stage: Driven by the transmission component 52, the peeling block 51 extends to the side away from the first material film transition roller 40, and the movable roller 53 adjusts its position synchronously with the peeling block 51 to reserve enough space for the material film to enter.

[0043] Material pulling and positioning stage: The film drive roller 20 rotates under the drive of the second drive motor 70, pulling the film out from the film mounting roller 30, passing through the first film transition roller 40 (guide) and the film tensioning block 80 (flattening) in sequence, until the film is pulled to the preset separation position (located between the peeling block 51 and the movable roller 53). Then the film drive roller 20 stops rotating to keep the film tension stable.

[0044] Separation and suction stage: Under the drive of the first drive motor 60, the peeling block 51 and the movable roller 53 move synchronously to the side closer to the first material film transition roller 40, cutting into the interlayer auxiliary bottom film and the upper film to initially separate; at this time, the suction head moves to the top of the material film and sucks up the upper film (adhesive connector) through negative pressure adsorption, which will be used for the subsequent connection of new and old material strips.

[0045] Reset phase: After the suction head picks up the upper film, the peeling block 51 returns to the initial position under the drive of the transmission component 52, the movable roller 53 resets synchronously, the film drive roller 20 resumes rotation, continues to pull the bottom film to itself and completes the storage, and prepares for the next film supply.

[0046] Furthermore, the film feeding assembly also includes a second film transition roller 90, which is located below the movable roller 53; the film passes from the film mounting roller 30 through the first film transition roller 40, the peeling block 51, the movable roller 53, the second film transition roller 90, and the film drive roller 20; the film has a first direction from the first film transition roller 40 to the peeling block 51, a second direction from the peeling block 51 to the movable roller 53, and a third direction from the movable roller 53 to the second film transition roller 90; the first direction, the second direction, and the third direction are arranged in parallel.

[0047] Specifically, in this embodiment, the second film transition roller 90 is a rotatable roller-shaped component that guides the film from the movable roller 53 to the film drive roller 20. Located below the movable roller 53, it, along with the first film transition roller 40 and the movable roller 53, adapts to the design requirements of the film transmission direction, becoming a guiding component between the movable roller 53 and the film drive roller 20, ensuring a continuous and stable film transmission path. The film transmission path, with the addition of the second film transition roller 90 node, forms a complete path: after exiting the film mounting roller 30, it sequentially passes through the first film transition roller 40, the film tensioning block 80, the peeling block 51, the movable roller 53, and the second film transition roller 90, finally reaching the film drive roller 20; simultaneously, the path clearly divides into three parallel transmission directions. The first direction (X1) is the direction in which the film is conveyed from the first film transition roller 40 to the peeling block 51; the second direction (X2) is the direction in which the film is conveyed from the peeling block 51 to the movable roller 53; the third direction (X3) is the direction in which the film is conveyed from the movable roller 53 to the second film transition roller 90. The first, second, and third directions are arranged in parallel, and the direction in which the peeling block 51 and the movable roller 53 move synchronously (moving towards or away from the first film transition roller 40) is also parallel to these three directions. The core purpose of this coordinated directional design is to improve the peeling accuracy between the bottom film and the top film, ensure that the separation action matches the film conveying direction, and avoid separation deviations caused by directional misalignment. In this embodiment, all three directions are parallel to the horizontal direction.

[0048] Furthermore, the transmission assembly 52 includes a fixed block 521, a slider 522, a slide rail 523, a gear 524, and a meshing block 525; the slide rail 523 is mounted on the mounting plate 10, and the slider 522 is slidably disposed on the slide rail 523; the fixed block 521 is mounted on the slider 522; the meshing block 525 is fixedly mounted on the fixed block 521, and the meshing block 525 has meshing teeth 526 that mesh with the gear 524; the gear 524 is connected to the shaft of the first drive motor 60.

[0049] Specifically, in this embodiment, the slide rail 523 has a long strip-shaped structure and is fixedly installed on the surface of the mounting plate 10. Its extension direction is parallel to the moving direction (i.e., horizontal direction) of the peeling block 51 and the movable roller 53, providing a stable sliding guide base for the slider 522 and serving as a guide reference component for the transmission assembly 52. ​​The block structure of the slider 522, which is adapted to the slide rail 523, can slide freely along the length of the slide rail 523. Its sliding direction is strictly constrained by the slide rail 523 to ensure accurate movement trajectory. It is an intermediate transmission component connecting the slide rail 523 with other actuators. The fixing block 521 is fixedly installed on the slider 522 and can slide synchronously with the slider 522 along the slide rail 523. One side of the fixing block 521 is used to connect the peeling block 51 and the movable roller 53, and the other side is equipped with the meshing block 525, serving as a connecting carrier for power transmission. The meshing block 525 is a component with a toothed structure, fixedly mounted on the fixing block 521. Its surface is machined with meshing teeth 526 that are adapted to the gear 524. The tooth profile parameters are perfectly matched with the gear 524 to ensure stable meshing and transmission between the two, making it a power receiving component. The gear 524 is directly connected to the output shaft of the first drive motor 60 (e.g., by key connection or coupling fixation) and can rotate synchronously with the motor shaft. Through meshing with the meshing block 525, it converts the rotational power of the motor into linear power, making it a power conversion component.

[0050] The transmission assembly 52, through the meshing of gear 524 and meshing block 525, combined with the guiding constraints of slide rail 523 and slider 522, forms a complete transmission chain of "rotational power → linear power → movement of actuator": the rotational power output by the first drive motor 60 is transmitted to meshing block 525 via gear 524, and meshing block 525 drives fixed block 521 and slider 522 to move linearly along slide rail 523, ultimately driving peeling block 51 and movable roller 53 to move synchronously. Throughout the transmission process, the power transmission direction is consistent with the extension direction of slide rail 523 (i.e., parallel to the preset movement direction of peeling block 51 and movable roller 53).

[0051] The rigid meshing of gear 524 and meshing block 525, compared to belt drive (prone to slippage) or linkage drive (prone to wear), can transmit power more accurately without power loss or delay. This ensures that the rotation angle output by the motor can be accurately converted into the linear displacement of meshing block 525, thereby making the moving distance and speed of peeling block 51 and movable roller 53 completely controllable and avoiding peeling position deviation caused by power transmission errors. Through the forward and reverse control of the first drive motor 60, the transmission component 52 can drive peeling block 51 and movable roller 53 to achieve bidirectional "extend-retract" movement: when rotating forward, it drives both to move closer to the first material film transition roller 40 to complete the auxiliary action of film separation; when rotating in reverse, it drives both to return to the initial position to prepare for the next material pulling and separation. This perfectly adapts to the complete operation process of the device "preparation-material pulling-separation-reset" without the need for an additional reverse drive mechanism, simplifying the component structure.

[0052] Furthermore, the peeling block 51 includes a main body 511 and a peeling part 512 connected to each other. The main body 511 is connected to the fixing block 521, the peeling part 512 is trapezoidal, and the sharp corner of the peeling part 512 faces away from the first film transition roller 40.

[0053] Specifically, the main body 511 has a rigid block or plate structure with stable structural performance. One side of it is connected to the fixed block 521 of the transmission component 52 by bolts or other rigid connections, and can move synchronously along the slide rail 523 with the fixed block 521. The other side is integrally formed or fixedly connected to the peeling blade 512, providing support and positioning for the peeling blade 512 and ensuring that the peeling blade 512 maintains structural stability during the peeling operation.

[0054] The peeling blade 512 adopts a trapezoidal structure design with a right-angled trapezoidal cross-section. It has two waist sides, an upper base side, and a lower base side, with a sharp angle between the sloping waist side and the base side. The sharp angle is located on the side away from the first film transition roller 40. The acute angle end (sharp angle) of the trapezoid is the working end of the peeling operation. The purpose of this sharp angle design is to make it easier to peel the upper film from the bottom film.

[0055] Furthermore, the peeling blade 512 is also provided with two spaced pressure blocks 54, the distance between the two pressure blocks 54 being less than the width of the film; and a track groove 55 is formed between the pressure blocks 54 and the peeling blade 512, the track groove 55 being used for the two sides of the film to pass through.

[0056] Specifically, two pressure blocks 54 are fixedly installed on the peeling section 512, and the two pressure blocks 54 are spaced apart in the direction of the film width. The horizontal distance between the two pressure blocks 54 is less than the width of the film, ensuring that the two edges of the film can be covered by the pressure blocks 54 during film transmission, and preventing the film from deviating beyond the constraint range of the pressure blocks 54 due to width deviation. The track groove 55 is formed by the two pressure blocks 54 and the upper surface of the peeling section 512: the inner sidewall of each pressure block 54 and the upper surface of the peeling section 512 form an elongated groove, and the two grooves extend along the film transmission direction, together forming the track groove 55 through which the film passes on both sides; the width of the track groove 55 is adapted to the thickness of the film edge (slightly greater than the film thickness). The constraint of the track groove 55 on both sides of the film can effectively offset the lateral tension fluctuations during the film transmission process (such as slight shaking when the film drive roller 20 pulls the film, and uneven local force when the movable roller 53 supports it), and prevent the film from wrinkling due to lateral force. At the same time, the smooth wall of the track groove 55 reduces the frictional resistance of the film edge, ensuring that the film is smoothly transmitted along the preset path, reducing the risk of film stretching deformation or breakage caused by edge jamming, and improving the overall transmission stability.

[0057] Furthermore, the film tensioning block 80 includes a base plate 81 and a cover plate 82 rotatably connected to the base plate 81, and the upper surface of the base plate 81 is coplanar with the upper surface of the peeling blade part 512.

[0058] Specifically, the base plate 81 is a rigid flat plate structure, mounted on the mounting plate 10. It serves as a support for the cover plate 82, with a flat upper surface providing stable support for the lifting of the film. The cover plate 82 is rotatably connected to one edge of the base plate 81 via a pivot, forming a flip-top structure. When closed, it forms a channel for the film to pass through between the cover plate 81 and the base plate 81. The upper surface of the base plate 81 is the lower surface of the channel, and the upper surface of the base plate 81 is on the same plane as the upper surface of the peeling section 512. This ensures that the film is horizontal as it moves from the first film transition roller 40 and the peeling section 512, maintaining a horizontal posture that matches the peeling section 512 within the tensioning block, preventing tilting or height deviation during transport. When entering the peeling section 512, it precisely aligns with the track groove 55, achieving lateral positioning without additional adjustments. This significantly reduces peeling deviation caused by film posture issues, providing a "standardized" material input for the sharp-corner separation of the peeling section 512. The flip-top design of the cover plate 82 gives the tensioning block a convenient opening and closing function: when changing the film, the film can be placed directly by opening the cover plate 82 without disassembling the tensioning block.

[0059] Furthermore, the film feeding assembly also includes a protective cover 91, which covers the first drive motor 60 and the second drive motor 70.

[0060] Specifically, the protective cover 91 is a rigid shell structure (materials such as metal sheets and engineering plastics can be selected). Its shape and size are adapted to the shape and installation position of the first drive motor 60 and the second drive motor 70—it can completely cover the two motors, forming a closed or semi-closed protective space. At the same time, the protective cover 91 is reserved with necessary heat dissipation holes (to prevent the motors from overheating) and maintenance openings (equipped with a removable cover plate 82). While achieving the protective function, it does not affect the normal heat dissipation and subsequent maintenance of the motors. It is a "protective dedicated component" specifically for the two drive motors. The protective cover 91 is fixedly installed on the mounting plate 10 by bolts, clips, and other detachable methods. The installation position corresponds exactly to the distribution area of ​​the two drive motors—since the first drive motor 60 and the second drive motor 70 are concentrated on the same side of the mounting plate 10 (power area), the protective cover 91 is also fixed to this side of the mounting plate 10, ensuring that both motors can be covered at the same time. There is no need to set up separate independent protective structures, simplifying the overall assembly.

[0061] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
