Description

Technical Field

[0001] This invention belongs to the technical field of PCB automated film application equipment, specifically relating to a collaborative control method for a dual-row film application system. 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 reserving a wide maintenance passage 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 limits the compact arrangement of production lines, making it difficult to adapt to high-density production demands. Summary of the Invention

Control the feeding and discharging mechanisms to perform actions opposite to the space release operation, returning them to their initial working positions.

[0008] In one embodiment of the present invention, the dual-row film application system further includes a displacement component. The first film application device and the second film application device are disposed on the displacement component so that they can move relative to each other in a predetermined direction. The first film application device and the second film application device are respectively provided with a locking mechanism below them so that the first film application device or the second film application device is locked and fixed when it moves to a predetermined position, so as to realize the centering and movable setting between the first film application device and the second film application device.

[0009] In one embodiment of the present invention, the collaborative control method in maintenance mode includes the following steps: Control the feeding mechanism of the second film-applying equipment to perform a lamination motion, or control the discharging mechanism of the second film-applying equipment to perform a folding motion; Control the second film-applying device to move away from the first film-applying device to create space on the side of the first film-applying device to form a maintenance workstation; The pressure roller of the first film application device is replaced at the maintenance station; Control the second film application device and its corresponding feeding and discharging mechanisms to perform actions opposite to the space release operation, and restore it to the initial working position.

The feeding mechanism of the second film-applying equipment is controlled to perform a stacking motion, which is used to form a maintenance station on the feeding side of the second film-applying equipment. At the maintenance station, the first and second film-applying devices are either stretched or cleaned.

[0012] In one embodiment of the present invention, the collaborative control method in maintenance mode includes the following steps: The material discharge mechanism of the first film-applying device is controlled to perform a folding motion, which is used to form a maintenance station on the material discharge side of the first film-applying device; The discharge mechanism of the second film-applying device is controlled to perform a folding motion, which is used to form a maintenance station on the discharge side of the second film-applying device.

By controlling the feeding mechanism and the discharging mechanism to perform folding or stacking movements, space is released on the side of the equipment to form a maintenance station. This eliminates the need to move the equipment outwards, thus saving factory space, simplifying maintenance operations, avoiding positioning deviations caused by moving the equipment outwards, and facilitating the integration of high-density production lines.

Detailed Implementation

[0018] 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.

[0019] In this application, the pressure roller is a device component used in the PCB film application field, including a metal roller core and an outer rubber sleeve, mainly used for pressing materials, such as pressing a film evenly onto a substrate.

[0020] The initial working position refers to the feeding mechanism 3 and the discharging mechanism 4 being connected and set at the feeding end and discharging end of the film-applying equipment, which is used to realize the feeding and discharging of the film-applying equipment.

[0021] Please refer to Figures 1-7 One embodiment of the present invention provides a collaborative control method for a dual-row film application system. The dual-row film application system includes a first film application device 1 and a second film application device 2 arranged in parallel. In maintenance mode, the feeding mechanism 3 and the discharging mechanism 4 are controlled to perform folding or stacking movements to release space on the side of the first film application device 1 or the second film application device 2. The released space forms a maintenance station without having to pull the first film application device 1 or the second film application device 2 outward. Among them, the stacking motion refers to the movable parts of the feeding mechanism 3 or the discharging mechanism 4 being stacked and retracted by bringing the multiple layers of the structure closer to each other; the folding motion refers to the movable parts of the feeding mechanism 3 or the discharging mechanism 4 being folded and retracted by rotating and changing their posture.

[0022] In this embodiment, when the space is released to the side of the first film-applying device 1 or the second film-applying device 2, the gap between the devices is directly used to form a maintenance workstation according to the specific execution result of the stacking or folding motion. As a result, maintenance personnel can immediately enter the workstation to perform operations, avoiding the need to move the entire set of equipment in the traditional method. This design not only effectively saves space resources but also significantly improves space utilization, adapting to the needs of compact production layouts. This technical solution solves the problem of having to pull the entire device outward to make room during maintenance operations of the double-row film-applying system by innovatively designing the movement mode of the feeding and discharging mechanisms 4, thereby reducing the equipment footprint and adapting to high-density production environments.

[0023] The feeding mechanism 3 includes a stacking drive mechanism and a board feeding conveyor section, with the stacking drive mechanism connected to the board feeding conveyor section. It is used to drive the board feeding conveyor section to adjust to an unfolded structure to move the circuit board to be laminated, and to drive the board feeding conveyor section to adjust to a stacked structure to form a maintenance station at the discharge end of the laminating equipment. The board feeding conveyor section includes a first feeding component 31 and a second feeding component 32. The stacking drive mechanism includes a first drive component 5 and a second drive component 6. The first feeding component 31 is movably disposed on the first drive component 5, and the first drive component 5 is used to drive the first feeding component 31 to move vertically. The second feeding component 32 is movably disposed on the second drive component 6, and the second drive component 6 is used to drive the second feeding component 32 to move closer to or further away from the laminating equipment.

[0024] The discharge mechanism 4 includes a rotary drive assembly 7, a plate conveying section 41, and a rotary shaft 8. The plate conveying section 41 is rotatably connected to the frame via the rotary shaft 8. The rotary drive assembly 7 is rotatably mounted on the frame via a rotating seat. The power output shaft of the rotary drive assembly 7 is rotatably connected to the plate conveying section 41.

[0025] In one embodiment of the present invention, the first film application device 1 and the second film application device 2 are either set with a pre-set offset distance or are set with a movable centering distance. The maintenance operations performed at the operation and maintenance workstation must include at least one of the following: replacing the pressure roller, installing the dry film, cleaning the equipment, or performing the film pulling operation.

[0026] In this embodiment, by optimizing the arrangement of the devices, the dual-row film application system can more efficiently free up space in maintenance mode. When a staggered preset distance is used, the inherent gaps between the devices can be directly used to form maintenance workstations, simplifying the space release process. The centering and movable arrangement provides greater flexibility, allowing the device positions to be adjusted according to specific maintenance needs. For example, when more operating space is required, the gaps can be widened by moving the devices. At the same time, the specific maintenance content of the maintenance workstations is clearly defined, including key operations such as replacing the pressure rollers and installing dry film, ensuring the functionality and practicality of the maintenance workstations. Based on the above solutions, not only is the problem of low space release efficiency solved, but the system's maintenance convenience is also significantly improved.

[0027] Please refer to Figure 2 In one embodiment of the present invention, when a pre-set offset distance is used between the first film application device 1 and the second film application device 2, the collaborative control method in maintenance mode includes the following steps: The feeding mechanism 3 of the second film-applying device 2 is controlled to perform a stacking motion, which is used to form a maintenance station on the feeding side of the second film-applying device 2 to replace the pressure roller of the first film-applying device 1; and / or, the discharging mechanism 4 of the first film-applying device 1 is controlled to perform a folding motion, which is used to form a maintenance station on the discharging side of the first film-applying device 1 to replace the pressure roller of the second film-applying device 2. Control the feeding mechanism 3 and the discharging mechanism 4 to perform actions opposite to the space release operation, and return to the initial working position.

[0028] In this embodiment, by setting a pre-staggered distance between the first film application device 1 and the second film application device 2, and combining the stacking or folding motion of the feeding mechanism 3 and the discharging mechanism 4, a maintenance workstation can be efficiently formed without pulling out the equipment. This method not only solves the problem of wasted space caused by reserving maintenance channels in traditional layouts, but also significantly improves the convenience of equipment maintenance, providing reliable technical support for the compact design of the dual-row film application system.

[0029] Please refer to Figure 2 In one embodiment of the present invention, when a pre-set offset distance is used between the first film application device 1 and the second film application device 2, the collaborative control method in maintenance mode includes the following steps: The discharging mechanism 4 of the second film-applying device 2 is controlled to perform a folding motion, which is used to form a maintenance station on the discharging side of the second film-applying device 2 to replace the pressure roller of the first film-applying device 1; and / or, the feeding mechanism 3 of the first film-applying device 1 is controlled to perform a stacking motion, which is used to form a maintenance station on the feeding side of the first film-applying device 1 to replace the pressure roller of the second film-applying device 2. Control the feeding mechanism 3 and the discharging mechanism 4 to perform actions opposite to the space release operation, and return to the initial working position.

[0030] In this embodiment, by coordinating the control of folding and stacking movements, not only is the space wastage problem caused by the overall movement of the equipment in the traditional layout solved, but the maintenance operation process is also greatly simplified, providing strong support for the compact design of the dual-row film application system. Especially in the scenario of staggered preset distance settings, this solution further optimizes the space utilization of the dual-row film application system by reasonably allocating maintenance space, demonstrating the ingenuity and practicality of the technical solution.

[0031] Please refer to Figures 6-7 In one embodiment of the present invention, the dual-row film application system further includes a displacement component 9. The first film application device 1 and the second film application device 2 are disposed on the displacement component 9 so that they can move relative to each other in a predetermined direction. The first film application device 1 and the second film application device 2 are respectively provided with locking mechanisms below them so that the first film application device 1 or the second film application device 2 is locked and fixed when it moves to a predetermined position, so as to realize the centering and movable setting between the first film application device 1 and the second film application device 2.

[0032] The displacement component 9 refers to a mechanical structure capable of driving the first film-applying device 1 and the second film-applying device 2 to move relative to each other along a predetermined direction. It can employ a high-precision linear guide rail and sliders. The first film-applying device 1 and the second film-applying device 2 are smoothly mounted on the linear guide rail by multiple sliders, and then moved to the predetermined position by means of servo motors, ball screw mechanisms, cylinder drives, or manual pushing. In practical applications, the design of the displacement component 9 must ensure the smoothness and accuracy of the equipment movement process, thereby providing a reliable foundation for subsequent operations. The locking mechanism refers to a device that can fix the equipment after it has moved to a designated position. It can be implemented by means of electromagnetic locks, mechanical pins, or hydraulic locking. The purpose of introducing the locking mechanism is to fix the film-applying equipment to the predetermined position on the guide rail, preventing the film-applying equipment from moving unexpectedly during the film-applying operation, thereby improving the safety and stability of the system.

[0033] In this embodiment, the organic combination of the displacement component 9 and the locking mechanism enables the centering and movable setting between the first film-applying device 1 and the second film-applying device 2. The displacement component 9 provides the equipment with flexible position adjustment capabilities, eliminating the need for additional wide passages during maintenance operations and significantly saving space. The locking mechanism ensures the stability of the equipment after it reaches the predetermined position, avoiding safety hazards caused by equipment shaking or displacement. This design not only solves the problem of potential instability during equipment movement but also improves the convenience of maintenance operations through precise positioning. Furthermore, the centering and movable setting allows the dual-row film-applying system to maintain high-efficiency maintenance capabilities even in a compact layout, thus adapting to the needs of high-density production in modern factories. Through the above technical solutions, the dual-row film-applying system significantly optimizes the convenience and safety of equipment maintenance while ensuring normal production efficiency, providing strong support for the compact layout of the production line.

[0034] Please refer to Figure 6 A schematic diagram of side A. In one embodiment of the present invention, the collaborative control method in maintenance mode includes the following steps: The feeding mechanism 3 of the second film-applying device 2 is controlled to perform a lamination motion, or the discharging mechanism 4 of the second film-applying device 2 is controlled to perform a folding motion; Control the second film application device 2 to move away from the first film application device 1 in a direction away from the first film application device 1, so as to release space on the side of the first film application device 1 to form a maintenance work station; Replace the pressure roller of the first film application device 1 at the maintenance station; Control the second film application device 2 and its corresponding feeding mechanism 3 and discharging mechanism 4 to perform actions opposite to the space release operation, and restore them to the initial working position.

[0035] In this embodiment, by performing spatial compression on the feeding mechanism 3 or discharging mechanism 4 of the second film-applying device 2, a preliminary operating space is freed up in a local area. Based on this, the movable characteristics of the displacement component 9 are used to control the second film-applying device 2 to move along a predetermined direction. This movement, in conjunction with the previous spatial compression action, can effectively expand the available space of the maintenance station. After completing maintenance operations such as replacing the pressure roller, the aforementioned actions are reversed to quickly restore the system to its initial working state. This step-by-step space management method makes full use of the structural characteristics of the dual-row film-applying system. While ensuring the convenience of maintenance operations, it avoids the cumbersome operation of pulling out the entire device in the traditional solution, significantly improving maintenance efficiency and optimizing space utilization.

[0036] Please refer to Figure 6 A schematic diagram of side B shows that, in one embodiment of the present invention, the collaborative control method in maintenance mode includes the following steps: The feeding mechanism 3 of the first film-applying device 1 is controlled to perform a lamination motion, or the discharging mechanism 4 of the first film-applying device 1 is controlled to perform a folding motion; Control the first film application device 1 to move away from the second film application device 2, so as to release space on the side of the second film application device 2 to form a maintenance work station; Replace the pressure roller of the second film application device 2 at the maintenance station; Control the first film application device 1 and its corresponding feeding mechanism 3 and discharging mechanism 4 to perform actions opposite to the space release operation, and restore them to the initial working position.

[0037] In this embodiment, the dual-row film application system includes a first film application device 1 and a second film application device 2 arranged side by side. The two are centrally movable and move relative to each other through a displacement component 9. When maintenance is required on the second film application device 2, the feeding mechanism 3 or discharging mechanism 4 of the first film application device 1 is first controlled to perform a corresponding retraction action. This mechanism retraction method effectively avoids interference from movable parts during the movement of the equipment. Subsequently, the first film application device 1 is controlled to move along a predetermined direction through the displacement component 9, directly releasing the maintenance workstation to the side of the second film application device 2. This method eliminates the need for reserving additional maintenance channels, significantly improving space utilization. After completing maintenance operations such as pressure roller replacement, the system can quickly return to the working state by reversing the aforementioned actions, ensuring production continuity.

[0038] Please refer to Figure 7 A schematic diagram of side C shows that, in one embodiment of the present invention, the collaborative control method in maintenance mode includes the following steps: The feeding mechanism 3 of the first film-applying equipment 1 is controlled to perform a stacking motion, which is used to form a maintenance station on the feeding side of the first film-applying equipment 1; The feeding mechanism 3 of the second film-applying equipment 2 is controlled to perform a stacking motion, which is used to form a maintenance station on the feeding side of the second film-applying equipment 2; At the maintenance station, the first film application equipment 1 and the second film application equipment 2 are respectively stretched or cleaned. Control the feeding mechanism 3 and the discharging mechanism 4 to perform actions opposite to the space release operation, and return to the initial working position.

[0039] In this embodiment, by controlling the feeding mechanism 3 of the first film-applying device 1 to perform a stacking motion, a maintenance station is formed on the feeding side of the first film-applying device 1, providing an independent operating space for the maintenance of the first film-applying device 1. At the same time, by controlling the feeding mechanism 3 of the second film-applying device 2 to perform the same stacking motion, another maintenance station is formed on the feeding side of the second film-applying device 2, providing an independent entry point for the maintenance of the second film-applying device 2. The parallel setting of the two maintenance stations allows the two devices to perform film-pulling or equipment cleaning operations simultaneously, significantly improving maintenance efficiency. In addition, by controlling the feeding mechanism 3 and the discharging mechanism 4 to perform actions opposite to the space release operation, the device can quickly return to the initial working position, thereby reducing downtime and ensuring the continuity of the production process.

[0040] Please refer to Figure 7 A schematic diagram of side D shows that, in one embodiment of the present invention, the collaborative control method in maintenance mode includes the following steps: The material discharge mechanism 4 of the first film application equipment 1 is controlled to perform a folding motion to form a maintenance station on the material discharge side of the first film application equipment 1; The discharge mechanism 4 of the second film-applying device 2 is controlled to perform a folding motion to form a maintenance station on the discharge side of the second film-applying device 2; At the maintenance station, dry film installation or roller cleaning is performed on the first film application device 1 and the second film application device 2. Control the feeding mechanism 3 and the discharging mechanism 4 to perform actions opposite to the space release operation, and return to the initial working position.

[0041] In this embodiment, when the first film application device 1 and the second film application device 2 are set with a pre-set offset distance or a movable centering setting, the folding motion of the discharge mechanism 4 can efficiently form a maintenance station on the discharge side, solving the problem of low space utilization in the prior art.

[0042] In one embodiment of the present invention, a collaborative control method for a dual-row film application system is described as follows: The dual-row film application system also includes a diversion and transfer machine and a diversion and merging device. Both the first film application device 1 and the second film application device 2 have a movably connected feeding mechanism 3 and a discharging mechanism 4. Under normal production mode, the collaborative control method includes the following steps: Control the feeding mechanism 3 and the discharging mechanism 4 to be in their initial working positions; The control diversion and transfer machine alternately distributes the circuit boards to be laminated on the main conveyor line to the feeding mechanism 3 of the first laminating equipment 1 and the second laminating equipment 2; The first film-applying device 1 and the second film-applying device 2 are controlled to alternately apply film to the received circuit boards to be filmed; The control steering and merging device alternately merges the film-coated circuit boards from the discharge mechanism 4 of the first film-coating device 1 and the second film-coating device 2 into the main conveyor line.

[0043] In this embodiment, by combining the diversion and transfer machine with the diversion and merging equipment, and utilizing the movable connection between the feeding mechanism 3 and the discharging mechanism 4 of the first film application device 1 and the second film application device 2, a highly efficient collaborative control mechanism is constructed. This solves the problems of a surge in the number of auxiliary equipment, excessive floor space, and low production efficiency caused by the independent setting of the feeding and discharging mechanisms 4 for each device in the traditional double-row film application system. It achieves the effects of simplifying the system structure, improving space utilization, and enhancing production continuity. Furthermore, in maintenance mode, the feeding mechanism 3 and the discharging mechanism 4 are controlled to perform folding or stacking movements, releasing space on the side of the first film-applying device 1 or the second film-applying device 2. The released space forms a maintenance workstation without having to pull the first film-applying device 1 or the second film-applying device 2 outward. Among them, the stacking movement refers to the movable parts of the feeding mechanism 3 or the discharging mechanism 4 being stacked and folded up by bringing the multiple layers of the structure closer to each other; the folding movement refers to the movable parts of the feeding mechanism 3 or the discharging mechanism 4 being folded up by rotating and changing their posture.
