[0036] Furthermore, between the pressing step and the punching step, the card manufacturing process also includes the following steps:

[0037] Pre-cut positioning: The pressed plate after pressing is conveyed to the positioning station, where the pressed plate is positioned so that it is aligned with the punching device.

[0038] Furthermore, the positioning station is equipped with a coarse positioning unit and a fine positioning unit, and the pre-cutting positioning step includes the following steps:

[0039] First positioning: The pressed plate after the pressing process is sent to the coarse positioning unit, and the coarse positioning unit is used to coarsely position the pressed plate.

[0040] Second positioning: The pressed plate after the first positioning is transferred to the precision positioning unit, and the precision positioning unit is used to accurately position the pressed plate.

[0041] Furthermore, in the first positioning step, the coarse positioning unit has a positioning space to accommodate the pressing plate, and multiple adjusting devices are arranged around the positioning space. At least one of the adjusting devices is arranged on each edge of the pressing plate. When the pressing plate is sent to the positioning space, the pressing plate is positioned by center positioning, centerline positioning, edge positioning or corner positioning using each of the adjusting devices.

[0042] Furthermore, the surface of the pressing plate has a first positioning mark and a second positioning mark, and the second positioning step includes the following steps:

[0043] First alignment: The pressed plate after the first positioning is sent to the fine positioning unit. The first positioning device on the fine positioning unit clamps the pressed plate and the position of the pressed plate is finely adjusted. At the same time, the first detection device on the fine positioning unit detects the first positioning mark so that the first positioning mark is aligned with the first standard position preset by the first detection device. After alignment, the first detection device feeds back the signal to the punching system of the punching station.

[0044] Second alignment: After receiving the feedback signal of successful first alignment, the punching system controls the second positioning device on the precision positioning unit to clamp the tail end of the pressing plate that is far from the punching device. After clamping, the clamping of the first positioning device is released, and the second positioning device on the precision positioning unit pushes the pressing plate toward the punching device. During the movement, the second detection device on the precision positioning unit detects the second positioning mark to determine the punching start edge position, the starting position of the clamping unit, or the position of each row of clamping units of the pressing plate, and feeds back the detection signal to the punching system of the punching station.

[0045] As an alternative, the positioning station is equipped with a coarse positioning unit and a fine positioning unit, and the pre-cutting positioning step includes the following steps:

[0046] First positioning: The pressed plate after the pressing process is sent to the coarse positioning unit, and the coarse positioning unit is used to coarsely position the pressed plate.

[0047] Second positioning: The fine positioning unit is used to accurately position the press plate after coarse positioning.

[0048] Furthermore, in the first positioning step, the coarse positioning unit has a positioning space to accommodate the pressing plate, and multiple adjusting devices are arranged around the positioning space. At least one of the adjusting devices is arranged on each edge of the pressing plate. When the pressing plate is sent to the positioning space, the pressing plate is positioned by center positioning, centerline positioning, edge positioning or corner positioning using each of the adjusting devices.

[0049] Furthermore, the surface of the pressing plate has a first positioning mark and a second positioning mark, and the second positioning step includes the following steps:

[0050] First alignment: The pressed plate after the first positioning is sent to the fine positioning unit. The first positioning device on the fine positioning unit clamps the pressed plate and the position of the pressed plate is finely adjusted. At the same time, the first detection device on the fine positioning unit detects the first positioning mark so that the first positioning mark is aligned with the first standard position preset by the first detection device. After alignment, the first detection device feeds back the signal to the punching system of the punching station.

[0051] Second alignment: After receiving the feedback signal of successful alignment from the first alignment, the punching system controls the second positioning device on the precision positioning unit to clamp the tail end of the pressing plate that is far from the punching device. After clamping, the clamping of the first positioning device is released, and the second positioning device on the precision positioning unit pushes the pressing plate toward the punching device. During the movement, the second detection device on the precision positioning unit detects the second positioning mark to determine the position of the punching start edge, the starting position of the clamping unit, or the position of each row of clamping units of the pressing plate, and feeds back the detection signal to the punching system of the punching station.

[0052] As an alternative, the positioning station is equipped with only a precision positioning unit, and the surface of the pressing plate has a first positioning mark and a second positioning mark. The pre-cutting positioning step includes the following steps:

[0053] First alignment: The pressed plate after pressing is sent to the precision positioning unit. The first positioning device on the precision positioning unit clamps the pressed plate and finely adjusts the position of the pressed plate. At the same time, the first detection device on the precision positioning unit detects the first positioning mark so that the first positioning mark is aligned with the first standard position preset by the first detection device. After alignment, the first detection device feeds back the signal to the punching system of the punching station.

[0054] Second alignment: After receiving the feedback signal of successful alignment from the first alignment, the punching system controls the second positioning device on the precision positioning unit to clamp the tail end of the pressing plate that is far from the punching device. After clamping, the clamping of the first positioning device is released, and the second positioning device on the precision positioning unit pushes the pressing plate toward the punching device. During the movement, the second detection device on the precision positioning unit detects the second positioning mark to determine the position of the punching start edge, the starting position of the clamping unit, or the position of each row of clamping units of the pressing plate, and feeds back the detection signal to the punching system of the punching station.

[0055] Furthermore, in the pre-cutting positioning step, if the positioning of the pressed plate after the pressing process fails, the pressed plate that failed to be positioned is sent to the material recycling bin or the waste recycling bin. At this time, the punching device of the punching station does not perform the punching step.

[0056] The present invention also provides a card production system, comprising:

[0057] Pre-positioning equipment is used to stack multiple raw material layers together to form a raw material plate, in preparation for subsequent pressing;

[0058] A pressing device for pressing the raw material plate to form a pressed plate; and...

[0059] A punching and cutting device is used to cut the pressed plate into multiple finished cards.

[0060] The beneficial effects of the card manufacturing process and system provided by this invention are as follows: Card manufacturing requires pre-positioning, pressing, and punching steps to finally obtain a finished card that meets the requirements. In the pre-positioning step, multiple raw material layers are stacked together to form a raw material plate, which is still in a state of separation between layers. When the raw material enters the pressing process for pressing treatment, a pressing plate is formed. At this time, the raw material layers are pressed and bonded together. Finally, the punching step punches the pressing plate into multiple finished cards. The manufacturing process is relatively simple and can realize automated and intelligent operation, improving the production efficiency of finished cards. Attached Figure Description

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0075] Please refer to the following as well. Figures 1 to 6 This invention provides a card manufacturing process, which includes the following steps:

[0076] S10: Pre-positioning. Multiple raw material layers are stacked together to form a raw material plate.

[0077] Multiple raw materials are stacked together using a pre-positioning device 100 to ultimately form a raw material plate.

[0078] Specifically, the pre-positioning device 100 includes multiple storage bins 110, a conveying device 120, a flipping device 130, a detection device 140, and a layer positioning device 150. Each raw material layer is stacked in its respective storage bin 110. One or more conveying devices 120, each corresponding to one storage bin 110, convey each raw material layer in a predetermined order and place it in the positioning area of ​​the layer positioning device 150. During conveying, the detection device 140 detects the front and back of each raw material layer, and the flipping device can be used for coordinated adjustment to ensure that the information of each layer is relative, achieving the predetermined effect.

[0079] Step S10 specifically includes the following steps:

[0080] S11: Layer positioning. Each raw material layer is pre-marked with positioning marks. Multiple raw material layers are stacked together in a predetermined order, and each raw material layer is adjusted so that the positioning marks of any two adjacent raw material layers are aligned to form a raw material group.

[0081] In this embodiment, multiple raw material layers are stacked together in a pre-set order or as required, and each raw material layer is adjusted so that the positioning marks on any two adjacent raw material layers are aligned or overlapped. This operation ensures that the independent information units on each raw material layer correspond and align layer by layer, preparing for the subsequent formation of independent, information-consistent finished product cards. Using the layer positioning device 150 of the pre-positioning device 100, each raw material layer is stacked in the positioning area of ​​the layer positioning device 150. Positioning adjustments are made to each raw material layer in the positioning area, aligning or overlapping the positioning marks on any two adjacent raw material layers to achieve a pre-positioning effect, forming a raw material group in the positioning area. The positioning area can be a positioning groove adapted to each raw material layer, or it can be adjusted and shifted using the layer positioning device 150 to achieve the pre-positioning effect.

[0082] S12: Initial Fixing. The raw material assembly is initially fixed to form a raw material plate.

[0083] In step S12, the stacked raw material group is initially fixed. This initial fixing is only to prevent the relative misalignment of each raw material layer under external force, which would damage the already established layer positioning. Generally, the initial fixing is performed in the peripheral material area of ​​the raw material group. The fixing method can be hot melt welding, gluing, binding, etc. Any fixing method that can satisfy the fixing and does not affect subsequent operations can be used, and there is no limitation here. In this embodiment, hot melt spot welding is preferred for the initial fixing treatment of the four edges of the raw material group. The pre-positioning device 100 also includes a fixing device 160, which is used to perform hot melt spot welding on the peripheral area of ​​the raw material group located in the positioning area, so that the aligned raw material layers are relatively fixed to form a raw material plate, thus completing step S12.

[0084] In this embodiment, the entire raw material plate formation process eliminates manual operation, saving time and effort, making card production more automated and intelligent, which helps to improve production efficiency and reduce labor costs.

[0085] S20: Initial positioning. The raw material board is conveyed to the loading station, which is equipped with a storage device 400. The storage device 400 is equipped with a positioning groove. Multiple raw material boards are stacked in the positioning groove. The perimeter of each raw material board is adapted to the shape of the positioning groove. That is, after the raw material board is placed in the positioning groove, there will be no displacement. The initial positioning of the raw material board is completed.

[0086] S30: Loading. The loading station is also equipped with a loading device 500, which conveys the raw material plates in the positioning slot one by one from top to bottom and performs the next pressing step.

[0087] In step S20, the positioning slot of the storage device 400 can accommodate multiple raw material plates and can simultaneously perform initial positioning of each raw material plate.

[0088] In this embodiment, the material storage device 400 at the feeding station is used to initially position the raw material plate, which facilitates accurate docking and pressing during the subsequent pressing step, thereby improving the efficiency of card production.

[0089] Specifically, the loading station includes a storage device 400 and a loading device 500. The storage device 400 typically has at least two positioning slots, each capable of accommodating multiple raw material boards and providing initial positioning for each board, ensuring they fit perfectly into their respective slots. Driven by a drive unit, the storage device 400 reciprocates relative to the loading station, aligning the loaded positioning slot with the loading device 500. The loading device 500 then loads the boards from the corresponding slots, while the unloaded slots move to one side of the loading device 500 for loading operations. This allows for continuous initial positioning and loading operations, improving raw material board conveying efficiency and pressing accuracy, thereby increasing the yield rate of card production.

[0090] In this embodiment, two positioning slots are provided, arranged side by side, and move laterally under the drive of the drive device. When one positioning slot is unloaded, the drive device moves the unloaded positioning slot out of the feeding position for material replenishment. At the same time, the other loaded positioning slot moves synchronously to the feeding position to continue the feeding operation of the feeding device. Of course, the number and arrangement of positioning slots are not limited to this and can be designed according to needs. This further improves the efficiency of card production.

[0091] S40: Pressing. The raw material plates are pressed together to form a pressed plate.

[0092] The pressing step is completed by the cooperation of hot pressing station and cold pressing station.

[0093] Step S40 includes the following steps:

[0094] S41: Hot pressing. The raw material plate conveyed by the feeding device 500 is obtained by the hot pressing feeding device and sent to the hot pressing station. The hot pressing unit 210 of the hot pressing station is used to perform high-temperature lamination to form a laminated plate.

[0095] The heating method of the hot pressing unit 210 can be selected from different methods such as electricity, magnetism, and light, as long as the desired effect is achieved. In this embodiment, the hot pressing unit 210 is equipped with a heating element and a temperature sensing element, which can realize temperature control to reach the required operating temperature. The heating element is a heating tube, and the temperature sensing element is a temperature sensor.

[0096] S42: Cold pressing. The high-temperature laminated platen is fed to the cold pressing station using a cold pressing feeding device. The cold pressing unit 220 in the cold pressing station performs flat pressing and cooling to form a shaped platen.

[0097] In this embodiment, the cold pressing unit 220 is equipped with cooling elements and temperature sensing elements, which can achieve temperature control to reach the required operating temperature. Cooling methods include contact ice cooling, air cooling, liquid cooling, vacuum cooling, etc. In this embodiment, the cold pressing unit 220 adopts liquid circulation cooling.

[0098] In step S41, the temperature during hot pressing by the hot pressing unit 210 is 110℃-150℃, the hot pressing pressure is 1MPa-6MPa, and the hot pressing time is 5s-15s.

[0099] In step S42, the temperature during cold pressing by cold pressing unit 220 is 10℃-25℃, the cold pressing pressure is 1MPa-6MPa, and the cold pressing time is 5s-15s.

[0100] The laminated board after flat-press cooling treatment has an interlayer peel strength greater than or equal to 6 N / cm, which meets the requirements of the card standard.

[0101] In this embodiment, there is no preheating station in the pressing step, yet the expected effect can still be achieved, improving the card pressing efficiency.

[0102] In this embodiment, the hot-pressing feeding device and the cold-pressing feeding device are the same feeding device 230. This feeding device 230 can transfer the material plate between the loading station, the hot-pressing station, and the cold-pressing station, and deliver the pressed plate after flat-pressing and cooling treatment to continue the subsequent punching steps. The material plate includes the raw material plate at the loading station, the pressed plate after high-temperature hot pressing, and the pressed plate after flat-pressing and cooling. In this way, the structure is simple, and the material plate can be transferred synchronously, thereby improving the pressing efficiency.

[0103] Specifically, the feeding device 230 has three conveying positions, namely the first conveying position, the second conveying position, and the third conveying position. Each conveying position can be controlled by the control system to perform material clamping and unloading actions.

[0104] When the feeding device 230 moves to the loading station to perform the loading operation, the hot pressing unit 210 and the cold pressing unit 220 are in the open state. The first, second, and third conveyor stations are sequentially opposite the loading station, the hot pressing station, and the cold pressing station and pick up the material plates from each station. It can be understood that the first conveyor station picks up the raw material plate conveyed by the feeding device 500, the second conveyor station picks up the pressed plate after high-temperature hot pressing at the hot pressing station, and the third conveyor station picks up the pressed plate after flat pressing and cooling at the cold pressing station. All three material plates are picked up at the same time.

[0105] When the feeding device 230 carries the material plate away from the loading station for conveying operations, the first and second conveying stations are sequentially opposite the hot pressing station and the cold pressing station. After the hot pressing unit 210 on the hot pressing station and the cold pressing unit 220 on the cold pressing station press the corresponding material plates, the feeding device 230 places the material plates on their respective stations, and the third conveying station sends the material plates out for punching processing. Understandably, the material plate on the first conveying station is opposite the hot pressing unit 210 on the hot pressing station, preparing for high-temperature lamination; the pressed plate on the second conveying station is opposite the cold pressing unit 220 on the cold pressing station, preparing for flat-press cooling processing; and the pressed plate on the third conveying station is sent away from the cold pressing station and to the pre-cutting positioning station for pre-cutting positioning processing. After the hot pressing unit 210 on the hot pressing station and the cold pressing unit 220 on the cold pressing station press the corresponding material plates, the three conveying stations simultaneously release the material.

[0106] In this embodiment, the feeding device 230 simultaneously performs material picking, conveying, and unloading at three workstations, achieving synchronous feeding, hot pressing, and cold pressing, which greatly improves the stability, efficiency, and pressing efficiency of the conveying process. Meanwhile, each conveying station is aligned with each workstation, and material is only released after each pressing unit has pressed the material plate. The feeding device 230's movement is controlled by the control system, effectively preventing material plate misalignment at each workstation and further improving the material plate pressing pass rate and pressing accuracy.

[0107] When the pressing step begins, each station is in an unloaded state. At the loading station, the loading device 500 can dock with the first conveyor of the feeding device 230. The first conveyor of the feeding device 230 picks up the raw material plate and moves it according to a predetermined stroke to deliver it to the hot pressing station. After it arrives, the hot pressing unit 210 presses the raw material plate. After pressing, the first conveyor releases the raw material plate, and the dispersed layers of raw material are pressed together. After the hot pressing station completes the hot pressing, the feeding device 230 moves to the loading station. At this time, the first and second conveyor stations can simultaneously pick up the raw material plate and the hot-pressed plate delivered by the loading device 500 and move in the opposite direction, delivering the hot-pressed plate to the cold pressing unit 220 of the cold pressing station. At the same time, the raw material plate is placed in the hot pressing unit 210 of the hot pressing station. The hot pressing unit 210 performs hot pressing on the raw material plate, and the cold pressing unit 220 performs cold pressing on the raw material plate. After hot pressing, the pressed plate undergoes flat pressing and cooling treatment. When both the hot pressing unit 210 and the cold pressing unit 220 have completed their processing, the feeding device 230 moves. At this time, the first, second, and third conveying stations can simultaneously acquire the raw material plate from the feeding device 500, the hot-pressed plate from the hot pressing station, and the cold-pressed plate from the cold pressing station, and move in the opposite direction. The raw material plate on the first conveying station is aligned with the hot pressing unit 210 at the hot pressing station, the pressed plate on the second conveying station is aligned with the cold pressing unit 220 at the cooling station, and the pressed plate on the third conveying station is conveyed to the next processing step. This process continues, meaning that the material transfer between the feeding station, the hot pressing station, the cold pressing station, and subsequent stations is all completed by the feeding device 230, improving the efficiency of the pressing process and achieving automation, integration, and intelligence.

[0108] In this embodiment, step S40 is completed by the pressing equipment 200, which includes a hot pressing unit 210 and a hot pressing feeding device at the pressing station, and a cold pressing unit 220 and a cold pressing feeding device at the cold pressing station, performing the work as described above. In this embodiment, the hot pressing feeding device and the cold pressing feeding device are the same feeding device 230.

[0109] The upper flat pressing end face of the hot pressing unit 210 is covered with an upper hot pressing composite structure, and its lower flat pressing end face is covered with a lower hot pressing composite structure. When the raw material plate is subjected to high-temperature hot pressing in the hot pressing unit 210, the hot pressing unit 210 performs high-temperature lamination on the raw material plate through the upper hot pressing composite structure and the lower hot pressing composite structure.

[0110] In this embodiment, the upper hot-pressing composite structure is attached to the upper flat-pressing end face of the hot-pressing unit 210 and fixed to the hot-pressing unit 210. The lower hot-pressing composite structure is attached to the lower flat-pressing end face of the hot-pressing unit 210 and fixed to the hot-pressing unit 210.

[0111] In this embodiment, the upper and lower hot-pressing composite structures serve two purposes: firstly, they act as a buffer to prevent excessive impact on the raw material plate during hot-pressing by the hot-pressing unit 210, thus avoiding damage; secondly, they increase the thermal resistance of the pressing surface, ensuring that the temperature rise curve of the raw material plate meets the specified requirements and preventing damage from rapid heating; thirdly, they effectively prevent foreign objects from entering between the pressing surfaces and damaging the upper and lower flat pressing end faces; and finally, they ensure the flatness of the pressed plate surface after hot pressing.

[0112] In this embodiment, the upper and lower pressing parts of the hot pressing unit 210 have a symmetrical structure.

[0113] The upper hot-press composite structure includes an upper hot-press buffer layer, an upper hot-press flat layer, and an upper hot-press electrostatic isolation layer. The upper hot-press electrostatic isolation layer, the upper hot-press flat layer, and the upper hot-press buffer layer are stacked sequentially from bottom to top on the upper flat end face of the hot-press unit 210 and fixedly connected to it.

[0114] The upper heat-pressing buffer layer can reduce the instantaneous impact force generated during pressing. It is an adhesive layer with rapid and uniform temperature conduction, high elasticity, and pressure-buffering properties; specifically, it can be made of silicone. This ensures uniform pressure distribution and prevents card deformation. Of course, the upper heat-pressing buffer layer can also be made of other materials with cushioning properties; there are no restrictions here.

[0115] The upper hot-pressing flat layer is a rigid plate with a certain degree of hardness, heat resistance, pressure resistance, and a smooth surface. Specifically, it can be a stainless steel plate. The function of this layer is to ensure the flatness of the material plate. Other rigid materials can also be used for the upper hot-pressing flat layer, as long as they meet the requirements; there are no restrictions here.

[0116] The upper hot-press electrostatic isolation layer is an antistatic fabric layer. This layer can act as a buffer on the one hand; on the other hand, it can increase the thermal resistance of the pressing surface and has high temperature resistance, ensuring that the temperature rise curve of the material plate meets the predetermined requirements; furthermore, it can isolate the static electricity generated between the upper hot-press flat pressing layer and the material plate, preventing the material layer on the material plate from sticking to the upper flat pressing end face of the hot pressing unit 210.

[0117] In this embodiment, the upper hot-press electrostatic isolation layer, the upper hot-press flat layer, and the upper hot-press buffer layer are stacked sequentially from bottom to top on the upper flat end face of the hot-press unit 210 and fixedly connected to the periphery of the hot-press unit 210. Specifically, they can be fixed by staples, wire, string, snap-fit ​​structures, etc.

[0118] The lower hot-press composite structure includes a lower hot-press buffer layer, a lower hot-press flat layer, and a lower hot-press electrostatic isolation layer. The lower hot-press electrostatic isolation layer, the lower hot-press flat layer, and the lower hot-press buffer layer are stacked sequentially from top to bottom on the lower flat end face of the hot-press unit 210 and fixedly connected to it.

[0119] In this embodiment, the materials used for the lower hot-pressing buffer layer and the upper hot-pressing buffer layer, the lower hot-pressing flat layer and the upper hot-pressing flat layer, and the lower hot-pressing electrostatic isolation layer and the upper hot-pressing electrostatic isolation layer are all the same, and their functions are also the same, so they will not be described in detail here.

[0120] The upper flat pressing end face of the cold pressing unit 220 is covered with an upper cold pressing composite structure, and its lower flat pressing end face is covered with a lower cold pressing composite structure. When the pressed plate after hot pressing is flat pressing and cooling in the cold pressing unit 220, the cold pressing unit 220 flat presses and cools the raw material plate therein through the upper cold pressing composite structure and the lower cold pressing composite structure.

[0121] In this embodiment, the upper cold-pressing composite structure is attached to the upper flat-pressing end face of the cold-pressing unit 220 and fixed to the cold-pressing unit 220. The lower cold-pressing composite structure is attached to the lower flat-pressing end face of the cold-pressing unit 220 and fixed to the cold-pressing unit 220.

[0122] In this embodiment, the upper and lower cold-pressing composite structures serve two purposes: firstly, they act as a buffer to prevent excessive impact on the hot-pressed plate during cold pressing by the cold pressing unit 220, thus avoiding damage to the hot-pressed plate; secondly, they increase the temperature conduction resistance of the pressing surface, ensuring that the temperature rise and fall curves of the raw material plate meet the specified requirements; thirdly, they effectively prevent foreign objects from entering between the pressing surfaces and damaging the upper and lower flat pressing end faces; and finally, they also ensure the flatness of the surface of the cold-pressed plate.

[0123] In this embodiment, the upper and lower pressing parts of the cold pressing unit 220 have a symmetrical structure.

[0124] The upper cold-press composite structure includes an upper cold-press buffer layer, an upper cold-press flat layer, an upper cold-press electrostatic isolation layer, and at least one upper cold-press laminate with a textured surface. The upper cold-press laminate, the upper cold-press electrostatic isolation layer, the upper cold-press flat layer, and the upper cold-press buffer layer are stacked sequentially from bottom to top on the upper flat end face of the cold-press unit 220 and fixedly connected thereto. The textured surface of the upper cold-press laminate faces the press plate after high-temperature lamination.

[0125] The upper cold-press buffer layer mitigates the instantaneous impact force generated during pressing. It is an adhesive layer with rapid and uniform temperature conduction, high elasticity, and pressure-buffering properties. Specifically, it can be made of silicone. The buffer layer ensures uniform pressure distribution and prevents card deformation. Of course, the upper cold-press buffer layer can also be made of other materials with cushioning properties; there are no restrictions here.

[0126] The upper cold-pressed flat layer is a rigid plate with a certain degree of hardness, heat resistance, pressure resistance, and a smooth surface. Specifically, it can be a stainless steel plate. The function of this layer is to ensure the flatness of the material plate. Other rigid materials can also be used for the upper cold-pressed flat layer, as long as they meet the requirements; there are no restrictions here.

[0127] The upper cold-pressed electrostatic isolation layer is an antistatic fabric layer. This layer can act as a buffer on the one hand; on the other hand, it can increase the thermal resistance of the pressing surface to ensure that the cooling curve of the material plate meets the predetermined requirements; furthermore, it can isolate the static electricity generated between the upper cold-pressed flat pressing layer and the material plate, and prevent the material layer on the material plate from sticking to the upper flat pressing end face of the cold pressing unit 220.

[0128] The upper cold-pressed laminate is made of antistatic plastic PC, with at least one surface having a uniform texture. This serves two purposes: firstly, it forms the desired texture on the card surface; secondly, it provides electrostatic isolation. In this embodiment, the upper cold-pressed laminate has a uniform texture on both sides. Specifically, the upper cold-pressed laminate is an 8B35 laminate, a novel thermoplastic with a transparency of up to 90%. It possesses strong toughness, high impact strength, good insulation properties, heat resistance, and is non-toxic. This material has excellent thermal properties and can be used long-term between -100℃ and 130℃.

[0129] In this embodiment, the upper cold-pressed laminate, the upper cold-pressed electrostatic isolation layer, the upper hot-pressed flat layer, and the upper hot-pressed buffer layer are stacked sequentially from bottom to top on the upper flat-pressed end face of the hot-pressing unit 210 and fixedly connected to the periphery of the hot-pressing unit 210. Specifically, they can be fixed by staples, wire, string, buckle structure, etc.

[0130] The lower cold-pressed composite structure includes a lower cold-pressed buffer layer, a lower cold-pressed flat layer, a lower cold-pressed electrostatic isolation layer, and at least one lower cold-pressed laminate with a textured surface. The lower cold-pressed laminate, the lower cold-pressed electrostatic isolation layer, the lower cold-pressed flat layer, and the lower cold-pressed buffer layer are stacked sequentially from top to bottom on the lower flat end face of the cold-pressing unit 220 and fixedly connected thereto. The textured surface of the lower cold-pressed laminate faces the press plate after high-temperature lamination.

[0131] In this embodiment, the materials used for the lower cold-pressed buffer layer and the upper cold-pressed buffer layer, the lower cold-pressed flat layer and the upper cold-pressed flat layer, the lower cold-pressed electrostatic isolation layer and the upper cold-pressed electrostatic isolation layer, and the lower cold-pressed laminate and the upper cold-pressed laminate are all the same, and they also serve the same function, so they will not be described in detail here.

[0132] S50: Pre-cutting positioning. The pressed plate after pressing is conveyed to the positioning station, where it is positioned to align with the punching device 310.

[0133] The so-called pre-cutting positioning refers to positioning the pressed plate, even after cold pressing, before punching to ensure that the punching head of the punching device 310 is aligned with the card unit of the pressed plate, thus ensuring accurate punching of the pressed plate and ultimately forming a qualified finished card. This step can effectively improve the qualification rate of the finished card.

[0134] I: Recycling. In step S50, if the positioning of the pressed plate after the pressing process fails, the failed pressed plate is sent to the material recycling bin 320 or the waste recycling bin 330. At this time, the punching device 310 of the punching station does not perform the punching step. That is to say, if the cold-pressed pressed plate is successfully positioned at the positioning station, the punching step continues; if the positioning fails, the recycling step is performed, which is the aforementioned step.

[0135] There are three detailed schemes for implementing step S50.

[0136] Option 1:

[0137] Please also refer to Figure 2 and Figure 4 The positioning station is equipped with a coarse positioning unit 340 and a fine positioning unit 350.

[0138] The pre-cut positioning steps include the following:

[0139] S51: First positioning. The pressed plate after the pressing process is sent to the coarse positioning unit 340. The coarse positioning unit 340 is used to perform coarse positioning on the pressed plate, thus completing the first positioning.

[0140] The purpose of the first positioning is to prepare for the fine-tuning of the subsequent second positioning.

[0141] In step S51, the coarse positioning unit 340 has a positioning space to accommodate the pressing plate. This positioning space can be a positioning groove adapted to the pressing plate to limit the peripheral movement of the pressing plate and achieve a positioning effect. Multiple adjustment devices are arranged around the positioning space, and each edge of the pressing plate is equipped with at least one adjustment device; when the pressing plate is delivered to the positioning space, the adjustment devices are used to perform center positioning, centerline positioning, edge positioning, or corner positioning of the pressing plate.

[0142] Preferably, the positioning device can move back and forth within a small range near the corresponding plate edge, forming a vibration or shaking motion. This helps the pressing plate to automatically align itself due to vibration, avoiding a single slippage into place that could cause the pressing plate to bend and deform due to a large tilt angle.

[0143] Assumptions: The pressing plate is rectangular, and each edge of the pressing plate corresponds to an adjustment device. The four positioning methods are as follows:

[0144] (1) During center positioning, all four adjusting devices are in a reciprocating sliding state, that is, they move closer to or further away from their corresponding plate edges. Center positioning means that the displacement of each adjusting device towards its corresponding plate edge is a fixed value. When the four adjusting devices slide towards each other to their respective fixed-value termination points, they will exactly abut against their respective plate edges, thus achieving center positioning of the press plate. Here, there are no restrictions on the order of sliding of the four adjusting devices or their number and layout, as long as the displacement value of each adjusting device is a fixed value. For example: all four adjusting devices can slide towards their respective corresponding plate edges simultaneously; or two opposing adjusting devices can slide towards their respective plate edges first, and then the remaining group of adjusting devices can slide; or two adjacent adjusting devices can slide towards their respective plate edges first, and then the remaining group of adjusting devices can slide; or a single adjusting device can slide towards its respective plate edge, etc. There are no restrictions here. Preferably, the four adjustment devices move simultaneously, and can move back and forth in a small range near the corresponding plate edge, forming a vibration or shaking. This helps the pressing plate to automatically align due to vibration, avoiding the pressing plate from bending and deforming due to a large tilt angle caused by sliding into place all at once.

[0145] (2) When performing centerline positioning, which is a special form of center positioning, the distance that any two opposing adjustment devices slide towards each other is a fixed value. When the two opposing adjustment devices slide towards each other to their respective fixed endpoints, they will exactly touch their corresponding plate edges, thus achieving centerline positioning. The centerline is the line of symmetry or the centerline between the two plate edges that are touching. Of course, the remaining two opposing adjustment devices can also operate in this way.

[0146] (3) When performing edge positioning, edge positioning is a special form of centerline positioning, in which one adjusting device is fixed and the other adjusting device opposite it slides toward it until both of the opposite adjusting devices are in contact with their respective edges. This achieves positioning based on one edge. Of course, the remaining two opposite adjusting devices can also be operated in the same way.

[0147] (4) When corner positioning is performed, the two adjacent adjustment devices are fixed and their relative positions are just able to abut against the two adjacent plate edges in the pressing plate to form a reference corner. The remaining two adjustment devices can move simultaneously to their respective plate edges or move one by one to push the pressing plate to the reference corner, thereby realizing the corner positioning of the pressing plate.

[0148] S52: Second positioning. The press plate after the first positioning is transferred to the precision positioning unit 350, which performs precise positioning on the press plate. This step allows the punching head of the punching device 310 to align with the card units to be punched on the press plate, thereby improving the pass rate of the finished cards after punching.

[0149] In Option 1, the first and second positioning are performed separately, with a certain distance between them. The press plate that has been coarsely positioned (also called the first positioning) is conveyed to the fine positioning unit 350 by the conveying device 360 ​​for precise positioning.

[0150] The surface of the pressed plate has a first positioning mark and a second positioning mark.

[0151] In this embodiment, the first positioning mark and the second positioning mark are the positioning marks in the layer positioning step S11. Of course, these marks can also be set differently, and there is no limitation here.

[0152] Step S52 includes the following steps:

[0153] S521: First alignment. The pressed plate after the first positioning is transferred to the precision positioning unit 350. The precision positioning unit 350 uses the first positioning device 351 on the precision positioning unit 350 to clamp the pressed plate and finely adjust the position of the pressed plate. At the same time, the first detection device 352 on the precision positioning unit 350 detects the first positioning mark so that the first positioning mark is aligned with the first standard position preset by the first detection device 352. After alignment, the first detection device 352 feeds back the signal to the punching system of the punching station.

[0154] S452: Second alignment. Upon receiving the feedback signal of successful first alignment, the punching system controls the second positioning device 353 on the precision positioning unit 350 to clamp the tail end of the pressing plate that is far from the punching device 310. After clamping, the clamping of the first positioning device 351 is released. The second positioning device 353 pushes the pressing plate toward the punching device 310. During the movement, the second detection device 354 on the precision positioning unit 350 detects the second positioning mark to determine the punching start edge position, the starting position of the clamping unit, or the position of each row of clamping units on the pressing plate, and feeds back the detection signal to the punching system at the punching station.

[0155] Assumptions: The pressing plate has a matrix of three rows and two columns of card units arranged horizontally and vertically. The pressing plate is pushed into the punching position along the vertical direction. The punching head of the punching device 310 punches one row of card units at a time. Of course, the aforementioned data can be adjusted according to actual needs. Let the first alignment mark be the vertical alignment mark of the pressing plate. When the first positioning mark is the centerline between the two columns of card units, the first detection device 351 has two alignment detection points. The line connecting the two alignment detection points is the centerline of the punching head of the punching device 310 extending along the vertical direction. Let the second positioning mark be the horizontal alignment mark of the pressing plate.

[0156] The specific adjustment method is as follows: The first positioning device 351 is located on one side of the pressing plate. The first positioning device 351 clamps one edge of the pressing plate and drags the edge laterally or swings it to adjust it, so that the first positioning mark coincides with the two alignment detection points of the first detection device 352. That is, if both detection points of the first detection device 352 detect the first positioning mark, it indicates that the longitudinal alignment of the pressing plate is complete, and a successful alignment signal is fed back to the punching system of the punching station as the starting condition for the second alignment. Upon receiving the feedback signal of the first successful alignment, the punching system controls the second positioning device 353 to clamp the tail end of the pressing plate furthest from the punching device. After clamping firmly, the clamping of the first positioning device 351 is released, preparing for the second alignment. If one of the two detection points of the first detection device 351 is not aligned or coincident with the first positioning mark, that is, if one of the two detection heads of the first detection device 351 fails to detect the first positioning mark, the positioning failure signal will also be fed back to the punching system of the punching station, and an alarm will be issued. Meanwhile, the second positioning device 353 continues to hold the tail end of the pressing plate and releases the clamping of the first positioning device 351. The second positioning device 353 on the precision positioning unit 350 pushes the pressing plate toward the punching device, and the recovery step I is executed directly, that is, there is no need to perform a second alignment.

[0157] Upon receiving the feedback signal of successful initial alignment, the punching system controls the second positioning device 353 to clamp the tail end of the pressing plate that is furthest from the punching device 310. After clamping, the first positioning device 351 releases the clamp, and the second positioning device 353 pushes the tail end of the pressing plate toward the inlet of the punching device 310. When the second detection device 354 detects the second positioning mark (a mark used to determine the starting position of the punching edge, the starting position of the clamping unit, or the position of each row of clamping units on the pressing plate), the detection signal is fed back to the punching system at the punching station. This achieves precise positioning of the clamping units on the pressing plate, facilitating more accurate punching by the subsequent punching device 310.

[0158] In this embodiment, the second positioning mark can be a starting positioning line, located at the front edge of the first row of card unit groups starting from the first end in the pressing plate. The second detection device 354 can determine the punching start position by detecting the starting positioning line. The second positioning mark includes two positioning lines, located on the transverse edge lines of the first row of card unit groups starting from the first end in the pressing plate. As the pressing plate advances towards the punching device 310, the second detection device 354 sequentially detects the two positioning lines to determine the position of the starting card unit to be punched. The second positioning line includes (N+1) positioning lines, where N is the number of rows in the array. Each positioning line is the edge line of each row of card units. In this way, as the pressing plate advances towards the punching device 310, the second detection device 354 sequentially detects each positioning line to determine the position of each card unit to be punched, better ensuring punching accuracy and avoiding cumulative errors.

[0159] In practical use, firstly, the number of pressing units on the pressing plate is not limited, and the array form can also be flexible; secondly, the first positioning mark line does not necessarily have to be a center line, but can be any vertical line, as long as it meets the requirement of being detected and positioned by the first detection device 352 so that it is laterally aligned with the punching head of the punching device 310. The first positioning mark can be a curve, a graphic, or a dot, as long as it is matched with the punching head of the punching device 310 after matching with the first detection device 352; thirdly, similarly, the second positioning line can also be a curve, a graphic, or a dot, as long as it is matched with the punching head of the punching device 310 after matching with the second detection device 354.

[0160] Both the first detection device 352 and the second detection device 354 contain sensors for detection marking.

[0161] The punching equipment 300 is installed at the positioning station and the punching station. The punching equipment 300 includes a punching system and punching devices 310, a coarse positioning unit 340, a fine positioning unit 350, and a conveying device 360, all of which are controlled and connected to the punching system. The third conveying position of the feeding device 230 conveys the pressed plate after being cold-pressed by the cold pressing unit 220 to the coarse positioning unit 340, where the coarse positioning unit 340 performs coarse positioning on the pressed plate. After coarse positioning is completed, the pressed plate is conveyed to the fine positioning unit 350 by the conveying device 360. The first positioning device 351 of the fine positioning unit 350 cooperates with the first detection device 352, and the second positioning device 353 cooperates with the second detection device 354 to achieve precise positioning of the pressed plate, ensuring that the punching device can accurately align with the card unit and achieve a precise punching effect. The punching equipment 300 also includes a card collection bin 370 and a waste recycling bin 330, and may also include a material recycling bin 320. When the punching device 310 punches the precisely positioned press plate, the finished card unit is conveyed to the card collection bin 370 for storage; while the cut-off scraps enter the waste recycling bin 330 for waste recycling. When the first detection device 352 of the precision positioning unit 350 fails to align, the punching system controls the second positioning device 353 to directly send the press plate to the material recycling bin 320 or the waste recycling bin 330. In this embodiment, the material recycling bin 330 is used for centralized processing. When the second positioning device 353 pushes the press plate that failed the detection, the punching device 310 remains in the open state.

[0162] Option 2:

[0163] Please also refer to Figure 2 and Figure 5 The positioning station is equipped with a coarse positioning unit 340 and a fine positioning unit 350.

[0164] The difference from Scheme 1 is that the first and second positioning are performed at the same workstation, eliminating the need for a 360° transfer device. Everything else is the same as Scheme 1, and will not be repeated here.

[0165] Step S50 includes the following steps:

[0166] S51: First positioning. The pressed plate after the pressing process is sent to the coarse positioning unit 340, and the coarse positioning unit 340 is used to perform coarse positioning of the pressed plate.

[0167] In step S51, the coarse positioning unit 340 has a positioning space to accommodate the pressing plate. This positioning space can be a positioning groove adapted to the pressing plate to limit the peripheral movement of the pressing plate and achieve a positioning effect. Multiple adjusting devices are arranged around the positioning space, and each edge of the pressing plate is equipped with at least one adjusting device. When the pressing plate is delivered to the positioning space, the adjusting devices are used to perform center positioning, centerline positioning, edge positioning, or corner positioning of the pressing plate. For details on the specific positioning method, please refer to Embodiment 1, which will not be repeated here.

[0168] S52: Second positioning. The fine positioning unit 350 is used to directly and accurately position the press plate after coarse positioning.

[0169] The surface of the pressed plate has a first positioning mark and a second positioning mark.

[0170] Step S52 includes the following steps:

[0171] S521: First alignment. The precision positioning unit 350 uses the first positioning device on the precision positioning unit 350 to clamp the pressing plate and finely adjust the position of the pressing plate. At the same time, the first detection device 352 on the precision positioning unit 350 detects the first positioning mark so that the first positioning mark is aligned with the first standard position preset by the first detection device 352. After alignment, the first detection device 352 feeds back the signal to the punching system of the punching station.

[0172] S522: Second alignment. Upon receiving the feedback signal of successful first alignment, the punching system controls the second positioning device 353 on the precision positioning unit 350 to clamp the tail end of the pressing plate that is far from the punching device 310. After clamping, the clamping of the first positioning device 353 is released. The second positioning device 353 pushes the pressing plate towards the punching device 310. During the movement, the second detection device 354 on the precision positioning unit 350 detects the second positioning mark to determine the punching start edge position, the starting position of the clamping unit, or the position of each row of clamping units on the pressing plate, and feeds back the detection signal to the punching system at the punching station.

[0173] For specific alignment methods, please refer to Scheme 1, which will not be elaborated here.

[0174] The punching equipment 300 is installed at the positioning station and the punching station. The punching equipment 300 includes a punching system and punching devices 310, a coarse positioning unit 340 and a fine positioning unit 350, all of which are controlled and connected to the punching system. The third conveying position of the feeding device 230 conveys the pressed plate after being cold-pressed by the cold pressing unit 220 to the coarse positioning unit 340. The coarse positioning unit 340 performs coarse positioning on the pressed plate. After the coarse positioning is completed, the first positioning device 351 and the first detection device 352 of the fine positioning unit 350 are used in conjunction with the second positioning device 353 and the second detection device 354 to achieve a precise positioning effect on the pressed plate, ensuring that the punching device can accurately align with the card unit and achieve a precise punching effect. The punching equipment 300 also includes a card collection bin 370 and a waste recycling bin 330, and may also include a material recycling bin 320. When the punching device 310 punches the precisely positioned press plate, the finished card unit is transported to the card collection bin 370 for storage; while the cut-off scraps enter the waste recycling bin 330 for waste recycling. When the first detection device 352 of the precision positioning unit 350 fails to align, the punching system controls the second positioning device 353 to directly send the press plate to the material recycling bin 320 or the waste recycling bin 330. In this embodiment, the material recycling bin 320 is used for centralized processing. When the second positioning device 353 pushes the press plate that failed the detection, the punching device 310 remains in the open state.

[0175] Option 3:

[0176] Please also refer to Figure 3 and Figure 6 The positioning station is equipped with a precision positioning unit 350, and the surface of the pressing plate has a first positioning mark and a second positioning mark.

[0177] The difference from Scheme 1 is that the pressing plate after the pressing process directly enters the precise positioning stage, without the need for two positioning adjustments. The following steps S51a are the same as step S521 in Scheme 1, and step S52a are the same as step S522 in Scheme 1.

[0178] Step S50 includes the following steps:

[0179] S51a: First alignment. The pressed plate after the pressing process is sent to the precision positioning unit 350. The precision positioning unit 350 uses the first positioning device on the precision positioning unit 350 to clamp the pressed plate and finely adjust the position of the pressed plate. At the same time, the first detection device 352 on the precision positioning unit 350 detects the first positioning mark so that the first positioning mark is aligned with the first standard position preset by the first detection device 352. After alignment, the first detection device 352 feeds back the signal to the punching system of the punching station.

[0180] S52a: Second alignment. Upon receiving the feedback signal of successful first alignment, the punching system controls the second positioning device 353 on the precision positioning unit 350 to clamp the tail end of the pressing plate that is far from the punching device 310. After clamping, the clamping of the first positioning device 351 is released. The second positioning device 353 pushes the pressing plate towards the punching device 310. During the movement, the second detection device 354 on the precision positioning unit 350 detects the second positioning mark to determine the punching start edge position, the starting position of the clamping unit, or the position of each row of clamping units on the pressing plate, and feeds back the detection signal to the punching system at the punching station.

[0181] For specific alignment methods, please refer to Scheme 1, which will not be elaborated here.

[0182] The punching equipment 300 is installed at the positioning station and the punching station. The punching equipment 300 includes a punching system, a punching device 310 and a precision positioning unit 350, both of which are controlled and connected to the punching system. The third conveying position of the feeding device 230 conveys the pressed plate after being cold-pressed by the cold pressing unit 220 to the precision positioning unit 350. By using the cooperation of the first positioning device 351 and the first detection device 352, and the cooperation of the second positioning device 353 and the second detection device 354 of the precision positioning unit 350, the precise positioning effect of the pressed plate is achieved, ensuring that the punching device can accurately align with the card unit and achieve a precise punching effect. The punching equipment 300 also includes a card collection bin 370 and a waste recycling bin 330, and may also include a material recycling bin 320. When the punching device 310 punches the precisely positioned press plate, the finished card unit is transported to the card collection bin 370 for storage; while the cut-off scraps enter the waste recycling bin 330 for waste recycling. When the first detection device 352 of the precision positioning unit 350 fails to align, the punching system controls the second positioning device 353 to directly send the press plate to the material recycling bin 320 or the waste recycling bin 330. In this embodiment, the material recycling bin 320 is used for centralized processing. When the second positioning device 353 pushes the press plate that failed the detection, the punching device 310 remains in the open state.

[0183] S60: Punching. Punching the laminated sheet into multiple finished cards.

[0184] After pre-cutting positioning, the pressed plate is sent to the punching station, where the punching device 310 punches the pressed plate. The punched finished card enters the card collection bin 320, while the punched scrap is conveyed to the waste recycling bin 330. The punching interval or punching frequency of the punching head of the punching device 310 is calculated based on the collected second positioning marks and the preset finished card specifications.

[0185] In this embodiment, the card manufacturing process involves pre-positioning, pressing, and punching steps to obtain a finished card that meets the requirements. In the pre-positioning step, multiple raw material layers are stacked together to form a raw material plate, which is still in a layer-separated state. When the raw material enters the pressing process, a pressing plate is formed, where the raw material layers are pressed and bonded together. Finally, the punching step cuts the pressing plate into multiple finished cards. The manufacturing process is relatively simple and can be automated and intelligently operated, improving the efficiency of finished card production.

[0186] In summary, firstly, multiple raw material layers are stacked together in a predetermined order using the layer positioning device 150. The layers are adjusted to align the positioning marks of any two adjacent layers, forming a raw material group. Then, the fixing device 160 performs initial fixing of the raw material group, forming a raw material plate. Although the layers of the raw material plate are relatively fixed at this point, they remain independent of each other, completing the pre-positioning of the raw material plate. Secondly, the raw material plate is conveyed to the storage device 400 at the loading station. The positioning groove of the storage device 400 is adapted to the shape of the raw material plate, achieving initial positioning. The loading device 500 at the loading station then delivers the raw material plate to the subsequent hot pressing station. Thirdly, pressing is performed by the hot pressing station and the cold pressing station. The process is complete. The feeding device 230 acquires the raw material plate from the loading device 500 and transfers it to the hot pressing station. The hot pressing unit 210 heats and presses the raw material. The feeding device 230 then moves towards the loading device, simultaneously acquiring the raw material plate from the loading device 500 and the pressed plate from the hot pressing station. It then moves away from the loading device 500, placing the raw material plate in the hot pressing station. The hot-pressed pressed plate is placed in the cold pressing station, where the hot pressing unit 210 heats and presses the raw material plate, and the cold pressing unit 220 flattens and cools the hot-pressed pressed plate to form a shaped pressed plate. At this point, the feeding device moves again towards the loading device 500, simultaneously acquiring the raw material plate from the loading device 500. The material plates are obtained from the hot pressing station (after hot pressing) and the cold pressing station (after cold pressing). Simultaneously, they are moved away from the feeding device, and three material plates are released: the raw material plate is placed at the hot pressing station, the hot-pressed plate at the cold pressing station, and the cold-pressed plate at the pre-cutting positioning station. This cycle repeats, achieving automatic feeding, hot pressing, transfer, and cold pressing of the raw material plates, improving the automation and intelligence level of card production and increasing pressing efficiency. Furthermore, the cold-pressed plate enters the coarse positioning unit 340 for initial positioning. Using the coarse positioning unit 340, the plate can be positioned at the center, centerline, edge, or corner, achieving a coarse positioning effect. As a result, in preparation for subsequent fine-tuning of precise positioning, the pressing plate after the first positioning is conveyed to the precision positioning unit 350 using the conveying device 360. The precision positioning unit 350 performs a second positioning of the pressing plate to achieve the effect of precise positioning. At this time, although it has not reached the punching station, the punching head of the punching device 310 has been aligned with each card unit in the pressing plate. If the positioning of the pressing plate is not completed, the pressing plate is pushed into the material recycling bin 320 or the waste recycling bin 330 for processing. Finally, the pressing plate that has been positioned before cutting is pushed into the punching station, and the punching head of the punching device 310 is used to perform positioning punching. The finished card enters the card collection bin 370, while the scrap material that has been punched off is conveyed to the waste recycling bin 330.The entire process makes full use of automation and intelligent technologies to achieve precise pressing and punching. Moreover, the pressed plates meet the requirements for peelability and flatness, thereby improving the production efficiency and pass rate of cards.

The raw material plate is then pressed using a pressing device 200 to form a shaped pressed plate. The pressed plate is then punched using a punching device 300 to form the final finished card. This process is completed automatically, improving the efficiency of card production.
