Description

Technical Field

[0001] This invention relates to the field of automatic copper foil-steel plate stacking technology, and more specifically, to an automatic feeding and synchronous stacking system and intelligent control method for copper foil and steel plate. Background Technology

[0002] Existing copper foil and steel plate lamination processes largely rely on manual labor or semi-automated equipment, which cannot achieve highly automated collaborative operation. Especially during the dual-material feeding and lamination process, due to the differences in physical properties between copper foil and steel plate, existing automated equipment struggles to synchronize the feeding and lamination rhythms, resulting in inconsistent feeding and lamination paces. This inconsistency often leads to instability in the lamination process, particularly on high-speed production lines, making it impossible to ensure precise coordination between feeding and lamination operations. Although some equipment has achieved partial automation, the lack of an effective collaborative control system still necessitates manual intervention to adjust the coordination between equipment, significantly limiting production efficiency and the overall level of system automation.

[0003] Therefore, there is an urgent need for a new solution that starts from the top-level design of the system and can achieve a deep integration of multi-path parallel feeding and dual-station synchronous stacking. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic feeding and synchronous stacking system and intelligent control method for copper foil and steel plate dual materials, so as to solve the above-mentioned problems existing in the prior art.

[0005] The application is as follows: An automatic feeding and synchronous stacking system for copper foil and steel materials includes: The copper foil feeding equipment is arranged longitudinally along the production line and is used to provide the upper copper foil material for the lamination process. The copper foil feeding equipment includes a double-layer copper foil conveying device, a copper foil lifting conveying device and a copper foil positioning platform arranged sequentially from front to back. The upper copper foil is then conveyed to each workstation by a copper foil suction and transfer device arranged above the above devices. The lower copper foil feeding equipment is arranged longitudinally along the production line and parallel to the upper copper foil feeding equipment. It is used to provide the lower copper foil material for the lamination process. The lower copper foil feeding equipment includes a lower copper foil double-layer conveying device, a lower copper foil lifting conveying device and a lower copper foil positioning platform arranged sequentially from front to back. The lower copper foil is then conveyed to each workstation by a lower copper foil suction and transfer device located above the above devices. The steel plate feeding equipment is arranged longitudinally along the production line and is set up laterally at an automatic stacking and exchange table with the upper and lower copper foil feeding equipment. It is used to provide steel plate material for the stacking process. The steel plate feeding equipment includes a steel plate double-layer conveying device, a steel plate lifting conveying device and a steel plate positioning platform arranged sequentially from front to back. The steel plate suction and transfer device set above the above devices sequentially conveys the steel plates to each workstation. The automatic stacking equipment includes a central suction and transfer device, a first automatic stacking and exchange table, and a second automatic stacking and exchange table. The first automatic stacking and exchange table is located between the upper copper foil feeding device and the steel plate feeding device, and the second automatic stacking and exchange table is located between the lower copper foil feeding device and the steel plate feeding device. The central suction and transfer device spans across the upper copper foil feeding device, the steel plate feeding device, and the lower copper foil feeding device, and its lateral travel range covers the area from the upper copper foil station to the lower copper foil station. It is used to stack the lower copper foil, steel plate, and upper copper foil sequentially in the order of "lower copper foil-steel plate-upper copper foil". The overall machine collaborative control system is used to coordinate the scheduling of each feeding device and the operation of the central suction and transfer device to achieve dual-path parallel superposition, wherein: The working path of the first central lifting and suction mechanism is configured to cover the positioning platform of each feeding module to form a first stacking line, which picks up materials from the first stacking line and stacks them on the first automatic stacking and exchange table. The working path of the second central lifting and suction mechanism is configured to cover the temporary storage platform of each feeding module, forming a second stacking line, which picks up materials from the second stacking line and stacks them on the second automatic stacking and exchange table. The overall collaborative control system has a built-in path mutual exclusion mechanism. When any central lifting and suction mechanism needs to enter the working area of ​​a certain feeding module, it must be confirmed that the suction and transfer device of that module is in a safe position to avoid path interference.

[0006] Furthermore, the double-layer conveying device, lifting conveying device, and positioning platform of the upper copper foil feeding device, steel plate feeding device, and lower copper foil feeding device are all configured as structural modules with the same function, and perform material receiving, lifting and carrying, and positioning storage with the same working logic.

[0007] Furthermore, the double-layer conveying device is equipped with a material storage platform, which has the same function as the positioning platform and is used to cooperate with the positioning platform to realize material storage positioning and cycle scheduling.

[0008] Furthermore, the double-layer conveying device is used to receive external materials and convey them to the lifting conveying device, the lifting conveying device is used to store materials, and the suction and transfer device is used to transfer materials from the lifting conveying device to the positioning platform and the material temporary storage platform respectively.

[0009] Furthermore, the automatic stacking equipment includes two transverse stacking lines. The positioning platform corresponds to the first stacking line, and the materials are stacked on the first automatic stacking exchange table. The material storage platform corresponds to the second stacking line, and the materials are stacked on the second automatic stacking exchange table.

[0010] Furthermore, the central suction and transfer device includes two central lifting suction mechanisms that are independently driven, independently controlled, and operate synchronously, and respectively cover the first and second overlapping lines to achieve parallel overlapping of the two lines.

[0011] Furthermore, each of the central lifting and suction mechanisms includes a lateral and lifting servo module as well as an adsorption component, with different adsorption components used when suctioning steel plates and copper foils.

[0012] Furthermore, both the first and second automatic stacking exchange stations adopt a longitudinal circulating disk changing structure to realize automatic disk switching and continuous stacking operations.

[0013] Furthermore, the upper copper foil and the lower copper foil have a distinction between a smooth surface and a rough surface. The material received by the upper copper foil feeding device has the rough surface facing up, while the material received by the lower copper foil feeding device has the smooth surface facing up. They are stacked in the order of "lower copper foil - steel plate - upper copper foil", with the smooth surface facing the steel plate in each stack.

[0014] A method for automatic feeding and synchronous stacking control of copper foil and steel plate, applied to the system described above, includes the following steps: S1 Material Conveying: The upper copper foil, steel plate and lower copper foil are respectively conveyed to the corresponding double-layer conveying device, and then conveyed to the lifting conveying device in sequence; S2 Material Transfer: The corresponding copper foil suction and transfer device and steel plate suction and transfer device pick up materials from each lifting and conveying device, and transfer them to the corresponding positioning platform and temporary storage platform respectively, so as to realize material pre-storage and cycle buffering. S3 First stacking line's pick-up and transfer: The first central lifting pick-up mechanism sequentially picks up the lower copper foil, steel plate, and upper copper foil from the lower copper foil positioning platform, steel plate positioning platform, and upper copper foil positioning platform, and stacks them sequentially on the first automatic stacking and exchange table; S4 Second Stacking Line Pickup and Transfer: When the first central lifting and picking mechanism picks up the lower copper foil on the lower copper foil positioning platform, the second central lifting and picking mechanism picks up the upper copper foil on the upper copper foil temporary storage platform, and the lower copper foil on the lower copper foil temporary storage platform has been picked up by the second central lifting and picking mechanism and transferred to the second automatic stacking and exchange table. The corresponding lower copper foil picking and transfer device will pick up the next piece of material on the lower copper foil lifting and conveying device and transfer it to the lower copper foil temporary storage platform. S5 Synchronous Stacking: The first and second central lifting suction mechanisms alternately adsorb and transfer materials on the first and second stacking lines, and automatically switch the adsorption mode according to the different materials. On the first and second stacking exchange platforms, the lower copper foil, steel plate and upper copper foil are stacked in sequence to form a copper foil-steel plate-copper foil sandwich stacking structure. S6 Stacking Material Exchange: When all materials in a cycle are stacked, the system controls the stacking exchange platform to perform cyclic switching of the pallets, outputting the stacked materials and placing the empty pallet into the stacking position to continue the next cycle of stacking.

[0015] Compared with the prior art, the embodiments of the present invention achieve the following beneficial effects: This invention achieves fully automated continuous feeding and synchronous stacking of copper foil and steel plates through three sets of feeding devices for upper copper foil, steel plates, and lower copper foil, along with an automatic stacking device. This avoids the problems of stoppages, waiting, and manual intervention caused by the difficulty in matching the feeding and stacking rhythms of traditional equipment. By setting up a dual-station feeding strategy with a positioning platform and a temporary storage platform, when any stacking and picking action occurs, the other material station simultaneously completes material replenishment, thus ensuring that each stacking station is always in a material-available state and that there is no situation where both the positioning and temporary storage platforms are short of material at the same time. This achieves non-interference and continuous operation of the feeding and stacking processes. The central picking and transferring device adopts dual independent central lifting and picking mechanisms, which can cover the upper and lower stacking lines in parallel, forming a multi-station synchronous stacking mode with consistent rhythms, significantly improving stacking efficiency. The overall device structure of this invention is modular, with unified rhythm logic and continuous and stable operation, which can significantly improve stacking efficiency, product consistency, and the level of production automation.

Above the double-layer conveying device, a temporary copper foil storage rack is also provided, which has the same positioning function as the positioning platform 13 and can serve as a buffer feeding point. When the copper foil material is conveyed to the lifting conveying device 12, the copper foil suction and transfer device 14 located above it sucks up the copper foil from the lifting conveying device 12 and transfers it to the temporary copper foil storage platform or the positioning platform 13 according to the cycle schedule, thereby achieving zoned management of feeding and buffering.

[0021] The layout of the lower copper foil feeding device 3 is the same as that of the upper copper foil feeding device 1.

It is used to stack the lower copper foil, steel plate, and upper copper foil sequentially in the order of "lower copper foil - steel plate - upper copper foil".

[0023] The overall machine collaborative control system is used to coordinate the scheduling of each feeding device and the operation of the central suction and transfer device to achieve dual-path parallel superposition, wherein: The working path of the first central lifting and suction mechanism is configured to cover the positioning platform of each feeding module to form a first stacking line, which picks up materials from the first stacking line and stacks them on the first automatic stacking and exchange table. The working path of the second central lifting and suction mechanism is configured to cover the temporary storage platform of each feeding module, forming a second stacking line, which picks up materials from the second stacking line and stacks them on the second automatic stacking and exchange table. The overall collaborative control system has a built-in path mutual exclusion mechanism. When any central lifting and suction mechanism needs to enter the working area of ​​a certain feeding module, it must be confirmed that the suction and transfer device of that module is in a safe position to avoid path interference.

The second stacking line is defined as "Upper copper foil temporary storage platform - Steel plate temporary storage platform - Second automatic stacking exchange table 43 - Lower copper foil temporary storage platform". The material is stacked on the second automatic stacking exchange table 43.

[0026] Below the central suction and transfer device 41, the upper copper foil feeding device 1, the first automatic stacking and exchange table 42, the steel plate feeding device 2, the second automatic stacking and exchange table 43, and the lower copper foil feeding device 3 are arranged horizontally in sequence. The first automatic stacking and exchange table 42 is located between the upper copper foil feeding device 1 and the steel plate feeding device 2, and the second automatic stacking and exchange table 43 is located between the lower copper foil feeding device 3 and the steel plate feeding device 2. The two automatic stacking and exchange tables are arranged longitudinally and parallel to each other, and are used to complete the automatic sandwich-style stacking operation of the upper and lower stacking lines respectively. The stacking sequence is lower copper foil—steel plate—upper copper foil, and the upper and lower stacking lines work synchronously without interfering with each other.

[0027] Preferably, the central suction and transfer device 41 includes a first and a second central lifting suction mechanism 412 that are independently driven, independently controlled and operate synchronously, and respectively cover the first and second overlapping lines to achieve parallel overlapping of the two lines.

[0028] Preferably, the central lifting and suction mechanism includes a lateral and lifting servo module and an adsorption component. Different adsorption components are used when suctioning steel plates and copper foils, and the suction is achieved by the contraction of the adsorption components.

[0029] Preferably, both the first automatic stacking exchange station 42 and the second automatic stacking exchange station 43 adopt a longitudinal circulating tray changing structure to realize automatic tray switching and continuous stacking operation.

[0030] This invention provides an automatic feeding and synchronous stacking control method for copper foil and steel plate, applied to the system described above, comprising the following steps: S1 Material Conveying and Scheduling: The upper copper foil, steel plate and lower copper foil are respectively conveyed to the corresponding double-layer conveying device, and then conveyed to the lifting conveying device in sequence; S2 Material Transfer: The corresponding copper foil suction and transfer device and steel plate suction and transfer device 34 pick up materials from each lifting and conveying device and transfer them to the corresponding positioning platform and temporary storage platform respectively, so as to realize material pre-storage and cycle buffer. S3 First stacking line's pick-up and transfer: The first central lifting pick-up mechanism 411 picks up the lower copper foil, steel plate and upper copper foil from the lower copper foil positioning platform 23, steel plate positioning platform 33 and upper copper foil positioning platform 13 in sequence, and stacks them in sequence on the first automatic stacking and exchange table 42. The whole machine coordinated control performs sequential adsorption, positioning and stacking actions on the first central lifting and suction mechanism 411, and automatically switches the adsorption components according to the material type during the adsorption process to complete the three-layer sequential stacking.

[0031] S4 Second stacking line's pick-up and transfer: When the first central lifting pick-up mechanism 411 picks up the lower copper foil on the lower copper foil positioning platform 23, the second central lifting pick-up mechanism 412 picks up the upper copper foil on the upper copper foil temporary storage platform, and the lower copper foil on the lower copper foil temporary storage platform has been picked up by the second central lifting pick-up mechanism 412 and transferred to the second automatic stacking exchange table 43.

On the first and second stacking exchange platforms, the lower copper foil, steel plate and upper copper foil are stacked in sequence to form a copper foil-steel plate-copper foil sandwich stacking structure. The system is set to a fixed stacking cycle T. The central lifting and suction mechanism alternately performs suction, transfer and stacking actions according to cycle T. In each cycle, the system judges the positioning status of the material and the locking mechanism for suction path conflicts. Only when all three types of materials are in the locked position and the mutual exclusion of suction paths is released, is the next suction action allowed. If any material is not yet in place, the current mechanism is kept in standby locked state, and the corresponding feeding equipment completes the replenishment to avoid cycle disorder and empty stacking.

[0032] S6 Stacking Material Exchange: When all materials in a cycle are stacked, the system controls the stacking exchange platform to perform cyclic switching of the pallets, outputting the stacked materials and placing the empty pallet into the stacking position to continue the next cycle of stacking.
