Description

Technical Field

[0001] This invention belongs to the technical field of PCB automated film application equipment, specifically relating to a double-row film application machine. Background Technology

[0002] In the printed circuit board (PCB) production process, PCBs to be processed need to be fed into laminating equipment for lamination before the finished product is output. Meanwhile, depleted dry film rolls are periodically replaced. To increase capacity, the industry commonly adopts a dual-row laminating layout, where two laminating machines are configured on a single production line. However, this traditional layout has significant drawbacks: equipment maintenance is extremely inconvenient. When performing routine operations such as film pulling, roller cleaning, or replacement, the entire conveyor unit or laminating body must be pushed away from the center of the production line along the track to create sufficient space for personnel. This design necessitates a wide maintenance aisle between the two production lines, leading to a surge in the number of auxiliary equipment such as the main conveyor line and steering gear, resulting in a significant increase in the overall equipment footprint. In the space-constrained environment of modern factories, this layout not only wastes valuable space resources but also prolongs maintenance cycles, increases the workload of operators, and may affect the stable operation of the production line due to frequent equipment movement. Furthermore, the existence of the maintenance aisle restricts the compact layout of the production line, making it difficult to adapt to high-density production demands. Summary of the Invention

[0003] The purpose of this application is to provide a double-row laminating machine, which has the advantages of reducing equipment redundancy, optimizing production line layout, saving equipment floor space, and facilitating equipment maintenance and operation.

The second film applicator includes a second film applicator body, a second infeed conveyor section, and a second outfeed mechanism. The first film applicator body and the second film applicator body are offset by a predetermined distance so that the first film applicator body is adjacent to the second infeed conveyor section or the second outfeed mechanism, and the second film applicator body is adjacent to the first infeed conveyor section or the first outfeed mechanism. The transfer and diversion machine includes a first conveyor mechanism, a second conveyor mechanism, and a transfer mechanism.

The second support base is built into the frame, and the material ejection assembly is rotatably connected to the second support base via a first rotating shaft. The third drive assembly is disposed on the second support base and is droop-connected to the material ejection assembly, driving the material ejection assembly to rotate to a horizontal position and close to the ejection ends of the first and second film-applying bodies, thereby moving the film-applying circuit boards. Alternatively, the material ejection assembly can be driven to rotate and fold to fit the second support base, thereby forming a third maintenance station at the ejection end of the first film-applying body and a fourth maintenance station at the ejection end of the second film-applying body.

[0008] Furthermore, the third drive assembly is rotatably mounted on the second support base via a rotating seat; a second rotating shaft is provided on the outer side of the discharge assembly, and the power output shaft of the third drive assembly is rotatably connected to the second rotating shaft.

The second maintenance station can then be formed by stacking and retracting the second feed plate conveyor section to replace the pressure rollers of the first film-applying body. Alternatively, the third maintenance station can be formed by rotating and folding the first output plate mechanism, and the first film-applying body can be moved and fixed within the third maintenance station.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1-6This application provides a dual-row film applicator, including a frame, a first film applicator 1, a second film applicator 2, a transfer and diversion machine 3, and a diversion and merging machine 4. The first film applicator 1 includes a first film applicator body 11, a first infeed conveyor section 12, and a first outfeed mechanism 13. The second film applicator 2 includes a second film applicator body 21, a second infeed conveyor section 22, and a second outfeed mechanism 23. The first film applicator body 11 and the second film applicator body 21 are staggered by a predetermined distance so that the first film applicator body 11 is adjacent to the second infeed conveyor section 22 or the second outfeed mechanism 23, and the second film applicator body 21 is adjacent to the first infeed conveyor section 12 or the first outfeed mechanism 13. The transfer and diversion machine 3 includes a first conveying mechanism 31, a second conveying mechanism 32, and a transfer mechanism. The first conveyor mechanism 31 is connected between the main conveyor line and the first board feeding conveyor section 12. The second conveyor mechanism 32 is connected to the second board feeding conveyor section 22. The transfer mechanism is spanned between the first conveyor mechanism 31 and the second conveyor mechanism 32 and is used to misalign and transport the board to be coated on the first conveyor mechanism 31 to the second conveyor mechanism 32. The turning and merging device 4 includes a third conveyor mechanism 41, a fourth conveyor mechanism 42 and a transverse movement mechanism 43. The third conveyor mechanism 41 is connected between the main conveyor line and the first board output mechanism 13. The fourth conveyor mechanism 42 is connected to the second board output mechanism 23. The transverse movement mechanism 43 is spanned between the third conveyor mechanism 41 and the fourth conveyor mechanism 42 and is used to misalign and transport the coated board on the fourth conveyor mechanism 42 to the third conveyor mechanism 41.

[0042] In this embodiment, when the first film-applying body 11 is arranged adjacent to the second board feeding section 22 or the second board output mechanism 23, maintenance space can be freed up by adjusting the state of the second board feeding section 22 or the second board output mechanism 23. Furthermore, the first board feeding section 12 and the second board feeding section 22 can adopt a telescopic structure design, such as a multi-segment slide rail or a folding bracket, to achieve flexible space adjustment. As a preferred embodiment, the first board output mechanism 13 and the second board output mechanism 23 can also achieve angle adjustment through a rotation mechanism to adapt to different operational needs. Specifically, the transfer mechanism can adopt a robotic arm or a slide structure, and realize the staggered transport of the printed circuit board to be film-applied through a drive device. Its main function is to improve transport efficiency and reduce the equipment footprint. In addition, the transverse movement mechanism 43 can be combined with a linear guide rail and a drive motor to achieve precise transverse movement, which is used to complete the staggered transport of the printed circuit board after film application.

[0043] This embodiment solves the problem of large footprint and inconvenient maintenance caused by the need to reserve a wide passage during the maintenance process of traditional double-row film applicators through staggered layout and collaborative design of functional modules. The staggered arrangement of the first film applicator 11 and the second film applicator 21 allows adjacent components to free up maintenance space by folding or retracting, avoiding the need for overall mobile equipment in traditional solutions. As a result, the overall layout of the equipment is more compact, and the operation time and space occupied for maintenance are significantly reduced, which meets the needs of high-density production environments.

[0044] In one embodiment, the first feeding conveyor section 12 and the second feeding conveyor section 22 are stackable components. The stackable components include a first support base 5, a first drive assembly 51, a first feeding assembly 52, a second drive assembly 53, and a second feeding assembly 54. The first support base 5 is built into the frame. The first drive assembly 51 is disposed on the first support base 5, and the first feeding assembly 52 is movably disposed on the first drive assembly 51, allowing the first drive assembly 51 to drive the first feeding assembly 52 to move vertically. The second drive assembly 53 is disposed on the top of the first support base 5, and the second feeding assembly 54 is movably disposed on the second drive assembly 53. Component 53 can drive the second feeding component 54 to approach the feeding end of the first film-applying body 11 and the second film-applying body 21, and the first feeding component 52 and the second feeding component 54 are flush, for driving the movement of the circuit board to be film-applied, or driving the second feeding component 54 to move below the first feeding component 52 to form a stacked structure, for forming a first maintenance station 100 at the feeding end of the first film-applying body 11 and a second maintenance station 200 at the feeding end of the second film-applying body 21, the first maintenance station 100 and the second maintenance station 200 are used to perform film pulling and front-end cleaning maintenance on the first film-applying body 11 and the second film-applying body 21.

[0045] In one application scenario of this embodiment, refer to Figure 1 When the first film-applying body 11 and the second feed plate conveying section 22 are arranged adjacent to each other, the second feed plate conveying section 22 is stacked up to form a second maintenance station 200 to replace the pressure roller of the first film-applying body 11.

[0046] Similarly, when the second film-applying body 21 is arranged adjacent to the first feed plate conveying section 12 (not shown), the first feed plate conveying section 12 is stacked and folded up to form the first maintenance station 100 for replacing the pressure rollers of the second film-applying body 21.

[0047] In this embodiment, the stackable component refers to a structural design that can dynamically adjust its spatial layout to adapt to different operational needs. It can be implemented using a multi-layer stacked or folding mechanical structure, with the aim of optimizing the space utilization of the equipment and improving maintenance efficiency. The first drive component 51 refers to a device that can provide vertical motion power, which can be implemented by electric push rods, hydraulic cylinders, or lead screw transmission mechanisms, with the aim of providing precise control for the lifting and lowering action of the first feeding component 52. The second drive component 53 refers to a device that can realize horizontal motion control, which can be implemented by linear motors, gear racks, or synchronous belt drives, with the aim of ensuring that the second feeding component 54 can move flexibly in the horizontal plane. The first feeding component 52 and the second feeding component 54 are functional components used to carry and transport printed circuit boards, which can be in the form of roller conveyors, belt conveyors, or chain conveyors, with the aim of ensuring the stability and reliability of material transport.

[0048] In one embodiment, the first driving assembly 51 includes a support frame 511, a guide rail 512, a first driving member 513, and a first slider 514; the support frame 511 is disposed on the first support base 5, the guide rail 512 is vertically disposed on the support frame 511, and the first slider 514 is slidably disposed on the guide rail 512 and connected to the first feeding assembly 52; the first driving member 513 is disposed on the first support base 5, and its power output end is drivenly connected to the first feeding assembly 52; the second driving assembly 53 includes a fixed plate 531 and a movable plate 532. The system comprises a first drive module 5 and a second drive module 534. The first drive module 5 is mounted on the top of the first support base 5 via a fixed plate 531, and a movable plate 532 is slidably mounted on the fixed plate 531 via a guide structure. The power output end of the first drive module 5 is drivenly connected to the movable plate 532. The second drive module 534 is fixedly mounted on the movable plate 532, and a second feeding assembly 54 is slidably mounted on the movable plate 532 via a guide structure. The power output end of the second drive module 534 is drivenly connected to the second feeding assembly 54.

[0049] In this embodiment, the efficient stacking and unfolding of the feeding assembly is achieved through the organic cooperation between the various components; the support frame 511 provides a stable mounting base for the guide rail 512, enabling the first slider 514 to drive the first feeding assembly 52 to move along a precise vertical trajectory. This vertical guiding mechanism effectively avoids horizontal deviation; the first driving component 513 directly drives the first feeding assembly 52, simplifying the transmission path and improving response speed and positioning accuracy; the fixed plate 531 serves as a reference platform, and the guide structure on it ensures that the moving plate 532 can slide smoothly along a straight line, while the second driving module 534 on the moving plate 532 further precisely controls the position of the second feeding assembly 54; this layered driving mechanism not only realizes the stacking and retraction of the feeding assembly in the vertical direction and the position adjustment in the plane, but also ensures the rapid construction of the maintenance station, significantly improving the compactness and maintenance efficiency of the equipment.

[0050] In one embodiment, the first board ejection mechanism 13 and the second board ejection mechanism 23 are foldable components. The foldable components include a second support base 6, a third drive assembly 61, and a material ejection assembly 62. The second support base 6 is built into the frame, and the material ejection assembly 62 is rotatably connected to the second support base 6 via a first rotating shaft 63. The third drive assembly 61 is disposed on the second support base 6 and is drivenly connected to the material ejection assembly 62. The third drive assembly 61 drives the material ejection assembly 62 to rotate to a horizontal position and close to the material ejection ends of the first film-applying body 11 and the second film-applying body 21, thereby driving the movement of the film-applying circuit board. Alternatively, the material ejection assembly 62 can be driven to rotate and fold to fit the second support base 6, thereby forming a third maintenance station 300 at the material ejection end of the first film-applying body 11 and a fourth maintenance station 400 at the material ejection end of the second film-applying body 21. The third maintenance station 300 and the fourth maintenance station 400 perform dry film installation and pressure roller cleaning and maintenance on the first film-applying body 11 and the second film-applying body 21.

[0051] In one application scenario of this embodiment, refer to Figure 1 When the second film-applying body 21 is arranged adjacent to the first plate-out mechanism 13, the first plate-out mechanism 13 is rotated and folded to form a third maintenance station 300 for replacing the pressure roller of the second film-applying body 21.

[0052] Similarly, when the first film-applying body 11 and the second plate-dispensing mechanism 23 are arranged adjacent to each other (not shown), the second plate-dispensing mechanism 23 is rotated and folded to form a fourth maintenance station 400 for replacing the pressure rollers of the first film-applying body 11.

[0053] In this embodiment, the foldable component refers to a mechanical device capable of switching structural states through a specific drive, which can be achieved by hydraulic drive, pneumatic drive, or electric motor drive. The second support base 6 serves as the foundation of the entire foldable component, providing a stable installation platform and avoiding loosening caused by frequent operation. The discharge assembly 62 is connected to the second support base 6 via the first rotating shaft 63. This design allows the discharge assembly 62 to rotate flexibly around the axis, thereby switching between a horizontal working state and a folding maintenance state. The third drive assembly 61 controls the rotation angle of the discharge assembly 62 through precise power output. During normal operation, the discharge assembly 62 is adjusted to a horizontal position, bringing it close to the discharge end of the film-coated body, thereby efficiently moving the film-coated circuit board. When maintenance is required, the third drive assembly 61 drives the discharge assembly 62 to fold into contact with the second support base 6, freeing up space at the discharge end and forming a maintenance station without the need for additional maintenance channels. This dynamically adaptable design significantly improves the compactness of the equipment and optimizes maintenance convenience. This embodiment avoids the cumbersome operation of traditional fixed structures that require pushing the equipment away during maintenance, thereby improving the operational stability of the production line and adapting to the needs of high-density production in modern factories.

[0054] In one embodiment, the third drive assembly 61 is rotatably mounted on the second support base 6 via a rotating seat 64; a second rotating shaft 65 is provided on the outer side of the discharge assembly 62, and the power output shaft of the third drive assembly 61 is rotatably connected to the second rotating shaft 65.

[0055] In this embodiment, the rotating seat 64 enables the third drive component 61 to have a follow-up adjustment capability. When the material discharge component 62 switches between the horizontal working position and the folding maintenance position, the third drive component 61 can automatically adjust its posture according to the movement trajectory, effectively avoiding jamming. The second rotating shaft 65 serves as the rotation fulcrum of the material discharge component 62, ensuring its accurate positioning when it is close to the material discharge end of the film-applying body or the bonding support seat, maintaining the stability of the printed circuit board conveying. At the same time, the rotational connection design between the power output shaft and the second rotating shaft 65 allows for relative rotation between the two during the transmission of driving force.

[0056] In one embodiment, the first conveying mechanism 31 and the second conveyor are both roller conveyor belts; the transfer and diverting machine 3 also includes a transfer support platform 34, on which the first conveying mechanism 31 and the second conveying mechanism 32 are both disposed, and the transfer support platform 34 has a groove that matches the gap of the roller conveyor belt; the transfer mechanism includes a translation module, a lifting module and a plurality of lifting components, the translation module is disposed below the transfer support platform 34, the lifting module is disposed at the drive end of the translation module, and the lifting components are disposed at the drive end of the lifting module, for rising from below the groove and driving the printed circuit board to translate during the operation of the translation module and the lifting module.

[0057] In this embodiment, the roller conveyor belt refers to a continuous conveying device composed of multiple rollers, which can be implemented using metal rollers or plastic rollers, with the aim of providing a low-friction conveying foundation to ensure the smooth operation of the printed circuit board; the transfer support platform 34 refers to a platform that supports the conveying mechanism and provides structural support for the transfer operation, which can be implemented by welding steel plates or splicing aluminum alloy profiles, with the aim of providing a stable support foundation for the entire transfer process; the chute is intended to allow the lifting component to pass through accurately without interfering with the normal operation of the conveyor belt; the translation module refers to a drive module that realizes horizontal movement, which can be implemented by using a screw drive or a linear motor, with the aim of providing precise horizontal displacement control; the lifting module refers to a drive module that realizes vertical lifting, which can be implemented by using a cylinder drive or an electric push rod, with the aim of providing controllable vertical movement.

[0058] In one embodiment, the merging device 4 further includes an upper center positioning mechanism, which is disposed below the fourth conveying mechanism 42. The upper center positioning mechanism includes a relatively movable centering clamp and an upper blade assembly. The upper center positioning mechanism is configured to position and lift the printed circuit board conveyed by the fourth conveying mechanism 42. The transverse mechanism 43 includes a linear moving module, a board picking arm, and a vacuum adsorption assembly. The linear moving module is fixedly disposed above the third conveying mechanism 41 and the fourth conveying mechanism 42. The drive end of the linear moving module is drivenly connected to the board picking arm. The vacuum adsorption assembly is disposed at the end of the board picking arm.

[0059] In this embodiment, the upper center positioning mechanism refers to a device that can achieve automatic centering and lifting functions. It can be implemented by using a pneumatic slide rail and a clamping plate structure driven by a servo motor. The purpose is to dynamically adjust the clamping point according to the actual position of the printed circuit board to ensure the accuracy of the board's center reference. The upper blade assembly can be understood as a set of support components that can be vertically lifted and lowered. It can be driven by a hydraulic cylinder or an electric push rod. The purpose is to lift the positioned printed circuit board off the conveyor belt surface to provide an interference-free suspended state for subsequent operations.

[0060] In this embodiment, the dynamic centering and lifting function of the top center positioning mechanism, combined with the precise adsorption and transfer of the transverse mechanism 43, ensures that the plate remains in a consistent position during the merging process after the film is applied.

[0061] In one embodiment, a buffer device, a preheating device, or a cleaning device is provided between the transfer splitter 3 and the first film application device 1 and the second film application device 2, for buffering, preheating, or cleaning the printed circuit board conveyed by the transfer splitter 3.

[0062] In this embodiment, the buffer device refers to a device capable of temporarily storing printed circuit boards. It can be implemented using a conveyor belt structure with multiple storage positions or a stacked storage rack, with the aim of balancing the speed of preceding and following processes according to the difference in production line cycle time. The preheating device can be a device that regulates the temperature of the printed circuit board through heating elements. It can be implemented using infrared heating technology or a hot air circulation system, with the aim of ensuring good adhesion performance of the film material during application. Specifically, the cleaning device refers to a device capable of removing dust or oil stains from the surface of the printed circuit board. It can be implemented using electrostatic dust removal technology or an air knife blowing structure, with the aim of improving the film application quality.

[0063] In one embodiment, when the first film-applying body 11 and the second board feeding conveyor section 22 are arranged adjacent to each other, the second board feeding conveyor section 22 is stacked and folded up to form a second maintenance station 200 for replacing the pressure rollers of the first film-applying body 11; or, when the first film-applying body 11 and the second board output mechanism 23 are arranged adjacent to each other, the second board output mechanism 23 is rotated and folded to form a fourth maintenance station 400 for replacing the pressure rollers of the first film-applying body 11.

[0064] In this embodiment, when the first film-applying body 11 is adjacent to the second infeed conveyor section 22, the stackable nature of the second infeed conveyor section 22 is utilized to vertically fold it up, thereby quickly releasing the second maintenance station 200 in the original position of the equipment. This design avoids the cumbersome operation of moving the entire equipment in traditional maintenance, significantly reducing space occupation and time consumption. When the first film-applying body 11 is adjacent to the second ejector mechanism 23, the foldable design of the ejector mechanism is used to rotate and fit it to the support seat, thereby forming the fourth maintenance station 400 in the original position of the equipment. This method specifically resolves the obstruction of the maintenance space by the ejector mechanism, so that the pressure roller replacement operation does not need to rely on external channels. Both methods are based on the inherent structural characteristics of adjacent components, and the maintenance station is embedded through reasonable design, fundamentally eliminating the necessity of reserving maintenance channels, while ensuring the compact layout and efficient operation of the production line.

[0065] In one embodiment, when the second film-applying body 21 is arranged adjacent to the first board feeding conveyor section 12, the first board feeding conveyor section 12 is stacked and folded up to form a first maintenance station 100 for replacing the pressure rollers of the second film-applying body 21; or, when the second film-applying body 21 is arranged adjacent to the first board output mechanism 13, the first board output mechanism 13 is rotated and folded to form a third maintenance station 300 for replacing the pressure rollers of the second film-applying body 21.

[0066] In this embodiment, when the second film-applying body 21 is adjacent to the first feed plate conveying section 12, the first feed plate conveying section 12 is compressed vertically to form a compact stacked structure by utilizing the characteristics of the stackable components. This design makes full use of vertical space and avoids the space waste caused by reserved channels in the traditional method. At the same time, when the second film-applying body 21 is adjacent to the first plate-discharging mechanism 13, the first plate-discharging mechanism 13 is fitted to the support seat by the rotation axis design of the foldable components, forming a state of minimizing space occupation. Both modes are based on the characteristics of the staggered layout of the equipment, accurately matching maintenance needs and ensuring that operations such as pressure roller replacement can be completed without interrupting the production process. In addition, this design complements the overall layout of the double-row film applicator, which not only optimizes space utilization but also improves maintenance efficiency, reflecting the design concept of a compact production line.

[0067] Please see Figures 6-7 In one embodiment, the first film-applying body 11 and the second film-applying body 21 are aligned and mounted on the frame via a sliding locking mechanism, forming a maintenance workstation:

[0068] The first film-applying body 11 is moved to the first maintenance station 100 or the third maintenance station 300 and fixed by a sliding locking mechanism;

[0069] The second film-applying body 21 is moved to the second maintenance station 200 or the fourth maintenance station 400 and fixed by a sliding locking mechanism.

[0070] In one embodiment, the first board ejection mechanism 13 is rotated and folded to form the third maintenance station 300, the first film-applying body 11 is moved and fixed in the third maintenance station 300, and the second board ejection mechanism 23 is rotated and folded to form the fourth maintenance station 400 for replacing the pressure roller of the first film-applying body 11.

[0071] Alternatively, the first maintenance station 100 can be formed by stacking and retracting the first feeding conveyor section 12, and the first film-applying body 11 can be moved and fixed within the first maintenance station 100. The second maintenance station 200 can be formed by stacking and retracting the second feeding conveyor section 22 to replace the pressure rollers of the first film-applying body 11. The third maintenance station 300 can be formed by rotating and folding the first dispensing mechanism 13, and the first film-applying body 11 can be moved and fixed within the third maintenance station 300. The fourth maintenance station 400 can be formed by rotating and folding the second dispensing mechanism 23 to replace the pressure rollers of the first film-applying body 11.

[0072] Alternatively, the first maintenance station 100 can be formed by stacking the first feed plate conveyor section 12, and the first film-applying body 11 can be moved and fixed in the first maintenance station 100. The second maintenance station 200 can be formed by stacking the second feed plate conveyor section 22 to replace the pressure roller of the first film-applying body 11.
