Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically to a stacking device. Background Technology

[0002] The high-speed thermal lamination stacking machine for lithium-ion batteries requires multiple processes during cell production, from cutting rolls of material into individual sheets, through thermal lamination, dimensional calibration, short-circuit testing, rejection of defective sheets, to stacking into cells. Among these, lamination stacking is a key technology, playing a decisive role in the alignment of the cells.

[0003] In the current double-stack lamination device, the hot composite strip is blown from one stack to another by compressed air during the switching process. The air volume fluctuates greatly due to the influence of the basic equipment, which causes the position of the first piece of the hot composite core package to shift during the stack switching process. This will seriously affect the lamination quality. Utility Model Content

[0004] The present invention provides a stacking device that can solve the problem in the prior art where the thermal composite strip is blown from one stacking platform to another by compressed air, resulting in the displacement of the first piece of the thermal composite core package during the stacking process, which seriously affects the stacking quality.

[0005] In a first aspect, embodiments of the present invention provide a stacking device.

[0006] In one embodiment, the stacking device includes:

[0007] Base;

[0008] A support unit is installed on the base, the support unit includes at least two stacks spaced apart along a first direction, each of the stacks having a support surface;

[0009] A feeding assembly is mounted on the base and positioned above the bearing portion. The feeding assembly is used to feed a strip of material to a plurality of bearing surfaces, such that the strip of material is suitable for stacking on each of the bearing surfaces to form a stack.

[0010] A blower unit is installed on the machine base and located above the stacking platform. The blower unit is used to blow the unstacked strip connected to the stacked sheet to be laid on another bearing surface.

[0011] The first pressing part is provided for each of the stacks, and the first pressing part is used to press the stacked pieces on the bearing surface.

[0012] In one embodiment, the first pressing part is provided on the opposite side of each of the two adjacent stacks, and the first pressing part is used to press the side of the stacked piece on the bearing surface away from the other stack.

[0013] In embodiments of this invention, the first pressing part presses the side of the stacked sheets away from another stacking platform, effectively preventing lateral displacement of the stacked sheets when subjected to external forces. Since a certain operating space is typically required between adjacent stacking platforms in a stacking device to avoid interference during stacking, conveying, or other processing, pressing the side of the stacked sheets away from another stacking platform by the first pressing part ensures the stacked sheets remain stable at that side, reducing potential operational interference between adjacent stacking platforms.

[0014] In one embodiment, the first clamping part includes:

[0015] A baffle is movably mounted on the machine base between a first pressing position and a first releasing position, extending along the normal direction of the bearing surface, and the baffle is used to abut against the end of the stacked pieces on the bearing surface;

[0016] A pressure block is installed on the baffle.

[0017] Specifically, when the baffle is in the first pressing position, the pressing block is used to press the side end of the stacked pieces together; when the baffle is in the first releasing position, the pressing block is used to release the stacked pieces together.

[0018] In embodiments of this invention, the baffle can shape and position the stacked sheets, improving their quality. A pressure block is installed on the baffle, wherein when the baffle is in the first pressing position, the pressure block is used to press the side ends of the stacked sheets. This design effectively prevents the stacked sheets from shifting or shaking due to external forces during processing or conveying, ensuring the accuracy of the stacked sheet position. The design of the baffle being movable along the normal direction of the bearing surface allows the pressing part to precisely switch between the first pressing position and the first releasing position. This control method ensures that the stacked sheets can be stably pressed when needed and easily released when not needed, improving operational flexibility and accuracy.

[0019] In one embodiment, the blowing unit includes two blowing air knives spaced apart along the first direction, each of the blowing air knives being adapted to blow air onto another stack adjacent to the stack where the stacked sheet is located.

[0020] In the embodiments of this utility model, the blowing action of the air knife helps guide the material to the target stacking platform, achieving rapid and accurate distribution of the material strip, reducing the need for manual intervention, improving production efficiency, and ensuring the consistency and accuracy of material strip distribution. Since each air knife can independently blow air onto adjacent stacking platforms, different air knives can be selected to operate according to actual production needs, thereby flexibly adjusting the blowing direction of the air knives and improving the adaptability and versatility of the stacking device.

[0021] In one embodiment, the airflow from the blowing air knife has an angle θ between its direction and the normal of the bearing surface of the corresponding stack, wherein 30°≤θ<90°.

[0022] In this embodiment of the invention, this design allows the airflow to act on the strip at a certain angle, ensuring that the unstacked strip is accurately guided to another bearing surface. The angle θ between the direction of the airflow from the blower and the normal to the bearing surface of the corresponding stack satisfies 30°≤θ<90°, allowing the airflow to act on the strip at an angle. The airflow force has horizontal and vertical components. The horizontal component guides the unstacked strip to move to the other bearing surface, while the vertical component allows the unstacked strip to lie flat on the other bearing surface, thereby improving the quality of the stack formed on the other bearing surface.

[0023] In one embodiment, a second clamping part is further included. The second clamping part is adapted to be movably mounted on the base between a second clamping position and a second loosening position along the normal extension direction of the bearing surface. In the second clamping position, the second clamping part is used to clamp the unstacked strip at a position adjacent to the stacked pieces. In the second loosening position, the second clamping part is used to loosen the strip.

[0024] In embodiments of this invention, when in the clamping position, the second clamping part can clamp the unstacked strip at a position adjacent to the stacked sheets. This prevents the stacked sheets formed by stacking on one bearing surface from shifting, and keeps the strip stable during stacking on another bearing surface, reducing stacking errors caused by strip movement or offset. This design significantly improves the accuracy and quality of stacking on another bearing surface, meeting the requirements of high-precision production.

[0025] In one embodiment, each of the air-blowing knives is provided with a corresponding second pressing part;

[0026] The stacking device further includes a mounting frame, wherein each of the air-blowing knives and the corresponding second pressing part are integrated into one unit by the mounting frame, wherein the mounting frame is adapted to be movably mounted on the base along the normal extension direction of the bearing surface.

[0027] In embodiments of this invention, by integrating each air-blowing knife with its corresponding second clamping part onto the mounting frame, this integrated design makes the overall structure of the stacking device more compact, helping to save floor space and improve space utilization. The integrated design of the air-blowing knife and the second clamping part allows them to work more closely together. While the air-blowing knife guides the unstacked strip, the second clamping part quickly clamps the strip, ensuring that the tail piece of the formed stack does not move while the first piece of the newly formed stack does not move, thus improving the quality of the stacks formed on adjacent bearing surfaces.

[0028] In one embodiment, the second clamping part has a clamping end face for abutting against the material strip, and the distance between the clamping end face and the air knife along the normal extension direction of the bearing surface is L, wherein 50m≤L≤200mm.

[0029] In embodiments of this utility model, the distance between the pressing end face and the air blowing knife is limited to the range of 50mm to 200mm, so that the pressing end face can press the material strip through physical contact, while the air blowing knife can guide the unstacked material strip to be accurately laid on another bearing surface through airflow.

[0030] In one embodiment, a first linear drive assembly is further included. The first linear drive assembly is mounted on the base and is drivenly connected to the second pressing part. The first linear drive assembly is used to drive the second pressing part to move.

[0031] In embodiments of this invention, the stacking device achieves precise control over the movement of the second pressing part through a drive connection between the first linear drive assembly and the second pressing part. The first linear drive assembly can automatically drive the second pressing part to switch between pressing and releasing positions according to a preset program or signal, without manual intervention, thus improving the automation level of the stacking device.

[0032] In one embodiment, a limiting part is provided on one side of each of the two adjacent stacks, and each limiting part is adapted to be movably installed on the base between a limiting position and an avoidance position along the normal extension direction of the bearing surface.

[0033] In the limiting position, the limiting part protrudes from the bearing surface and abuts against the end of the stacked piece adjacent to another stack on the bearing surface. In the avoidance position, the limiting part is lower than the bearing surface or flush with the bearing surface.

[0034] In embodiments of this invention, the limiting part provides a precise positioning reference for the stacked sheets, which helps ensure that the stacked sheets maintain the correct position and orientation during stacking, improves the alignment accuracy of the stacked sheets, and reduces quality problems caused by misalignment. In addition, the limiting part provides stable support and guidance during stacking, reducing shaking and offset during the stacking process, thereby improving the stability and production efficiency of the stacking. In the avoidance position, the limiting part is lower than or flush with the bearing surface. This ensures that unstacked strips can be blown by the air blower to lay on another bearing surface, avoiding interference or collision between the unstacked strips and the limiting part.

[0035] In one embodiment, a cutting component is further included, which is mounted on the machine base and cuts the unstacked strip at a position adjacent to the stacked sheets.

[0036] In this embodiment of the present invention, the two stacked pieces formed by two adjacent bearing surfaces are cut and separated, which facilitates subsequent processing of the stacked pieces.

[0037] In one embodiment, the support portion is movably mounted on the base along the first direction such that one of the at least two stacks is aligned with the unloading assembly.

[0038] In an embodiment of this utility model, the carrier can move along the first direction on the base, so that one of the at least two stacks can be aligned with the feeding assembly, thereby facilitating the feeding assembly to deliver the material strip to the aligned stack, reducing the offset and error of the material strip during the transmission process. This precise alignment control helps to ensure that the material strip is accurately delivered to the stack, thereby improving the quality and consistency of the stacked sheets and reducing the defect rate caused by inaccurate alignment.

[0039] In one embodiment, a lateral movement drive mechanism is further included. The lateral movement drive mechanism is mounted on the base and drivenly connected to the support portion. The lateral movement drive mechanism is used to drive the support portion to move.

[0040] In this embodiment of the invention, the transverse drive mechanism provides a power source for the carrier unit, enabling it to move precisely on the machine base according to a preset trajectory and speed. This precise movement is crucial for the stacking device, as it ensures that the stacking table is accurately aligned with the unloading component, thereby improving stacking accuracy and production quality. The addition of the transverse drive mechanism enables automated production of the stacking device, reducing the need for manual intervention and adjustments. Through a preset program or signal, the transverse drive mechanism can automatically drive the carrier unit to a designated position, thereby accelerating production speed and improving production efficiency.

[0041] The beneficial effects of the embodiments of this utility model are as follows:

[0042] In an embodiment of this invention, the support unit includes at least two stacking platforms spaced apart along a first direction. Each stacking platform has a support surface. The feeding assembly can convey the material strip to multiple support surfaces, allowing the material strip to stack on each support surface to form a stack. This design significantly improves stacking efficiency, enables multi-station parallel operation, and shortens the production cycle. The feeding assembly is mounted on the machine base and located above the support unit, ensuring that the material strip can be accurately and stably conveyed to each support surface to form neat stacks. The blowing unit is mounted on the machine base and located above the stacking platforms. It blows the unstacked material strip connected to the stacks onto another support surface, achieving automatic distribution and guidance of the material strip. This not only reduces manual intervention and improves production efficiency but also ensures the accuracy and consistency of material strip distribution. Each stacking platform is correspondingly provided with a first pressing part for pressing the stacks on the support surface. This design ensures the stability and tightness of the stack during the stacking process, preventing the stack from loosening or shifting when the blower blows the unstacked strip connected to the stack onto another bearing surface, thus improving the quality and reliability of the stack.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model.

[0052] In one aspect, this utility model provides a stacking device 100. (See also...) Figure 1 , Figure 1 This is a schematic diagram of the stacking device 100 provided in an embodiment of the present invention. The stacking device 100 includes a base 10, a support part 20, a feeding assembly 30, a blowing part 40, and a first pressing part 50. The support part 20 is installed on the base 10 and includes at least two stacking platforms 21 spaced apart along a first direction. Each stacking platform 21 has a support surface 211. The feeding assembly 30 is installed on the base 10 and is located above the support part 20. The feeding assembly 30 is used to feed material strips 200 to multiple support surfaces 211 so that the material strips 200 are suitable for stacking on each support surface 211 to form stacked sheets 300. The blowing part 40 is installed on the base 10 and is located above the stacking platform 21. The blowing part 40 is used to blow unstacked material strips 200 connected to the stacked sheets 300 to be laid on another support surface 211. Each stacking platform 21 is correspondingly provided with a first pressing part 50, which is used to press the stacked sheets 300 on the support surface 211.

[0053] In an embodiment of this invention, the support unit 20 includes at least two stacking platforms 21 spaced apart along a first direction. Each stacking platform 21 has a support surface 211. The feeding assembly 30 can convey the material strip 200 to multiple support surfaces 211, allowing the material strip 200 to stack on each support surface 211 to form a stack 300. This design significantly improves the efficiency of stacking 300, enables multi-station parallel operation, and shortens the production cycle. The feeding assembly 30 is mounted on the machine base 10 and located above the support unit 20, ensuring that the material strip 200 can be accurately and stably conveyed to each support surface 211 to form neat stacks 300. The blowing unit 40 is mounted on the machine base 10 and located above the stacking platform 21. By blowing air, the unstacked material strip 200 connected to the stack 300 is blown to be laid on another support surface 211, realizing automatic distribution and guidance of the material strip 200. This not only reduces manual intervention and improves production efficiency but also ensures the accuracy and consistency of material strip 200 distribution. Each stack 21 is provided with a first clamping part 50 to clamp the stacked sheets 300 on the bearing surface 211. This design ensures the stability and tightness of the stacked sheets 300 during the stacking process, and prevents the stacked sheets 300 from loosening or shifting when the blowing part 40 blows the unstacked strip 200 connected to the stacked sheets 300 to lay it on another bearing surface 211, thereby improving the quality and reliability of the stacked sheets 300.

[0054] It should be noted that, in the embodiments of this application, after one of the two adjacent bearing surfaces 211 completes the stacking 300, the feeding assembly 30 conveys the material strip 200 to the other bearing surface 211 to stack and form the stacked sheet 300 on the other bearing surface 211. In addition, in this application, the stacked sheet 300 refers to the structure formed after the material strips 200 are stacked.

[0055] Reference Figure 2 , Figure 2 yes Figure 1 The front view of the stacking device 100 shows that each of the two adjacent stacking platforms 21 has a first clamping part 50 on its opposite side. The first clamping part 50 is used to clamp the side end of the stacked piece 300 on the bearing surface 211 that is away from the other stacking platform 21. In this way, by clamping the side end of the stacked piece 300 away from the other stacking platform 21 by the first clamping part 50, the lateral displacement of the stacked piece 300 can be effectively prevented when subjected to external forces. Since a certain operating space is usually required between adjacent stacking platforms 21 in the stacking device 100 to avoid interference during stacking, conveying or other processing of the stacked piece 300, the clamping part 50 ensures that the stacked piece 300 remains stable at that side end, reducing possible operational interference between adjacent stacking platforms 21.

[0056] Combination Figure 3 and Figure 4 , Figure 3 yes Figure 1 The diagram shows a partial enlarged view of the first clamping part 50 and the stacking platform 21. Figure 4 yes Figure 1 The diagram shows a partially enlarged front view of the first clamping part 50 and the stacking platform 21. In some embodiments, the first clamping part 50 includes a baffle 51 and a pressing block 52. The baffle 51 is movably mounted on the machine base 10 between a first clamping position and a first loosening position, extending along the normal direction of the bearing surface 211. The baffle 51 abuts against the end of the stacked piece 300 on the bearing surface 211. Thus, the baffle 51 can shape and position the stacked piece 300, improving its quality. The pressing block 52 is mounted on the baffle 51, wherein, when the baffle 51 is in the first clamping position, the pressing block 52 is used to clamp the side ends of the stacked piece 300. This design effectively prevents the stacked piece 300 from shifting or shaking due to external forces during processing or conveying, ensuring the accuracy of the stacked piece 300's position. When the baffle 51 is in the first loosening position, the pressing block 52 is used to loosen the stacked piece 300, thus facilitating subsequent processing of the stacked piece 300. The design of the baffle 51, which is movable along the normal direction of the bearing surface 211, allows the clamping part to precisely switch between a first clamping position and a first releasing position. This control method ensures that the stacked sheets 300 can be stably clamped when needed and easily released when not needed, improving operational flexibility and accuracy. Furthermore, the first clamping part 50 consists of the baffle 51 and the pressure block 52, making its structure relatively simple and easy to install and maintain. Simultaneously, since the clamping and releasing operations are achieved through the movement of the baffle 51, the complex mechanical transmission and control system is reduced, lowering the complexity and maintenance cost of the stacking device 100.

[0057] Reference Figure 4The stacking device 100 also includes a clamping drive assembly 140, which is mounted on the base 10 and drivenly connected to the first clamping part 50. The clamping drive assembly 140 drives the first clamping part 50 to move between a first clamping position and a first releasing position. Thus, through the drive connection between the clamping drive assembly 140 and the first clamping part 50, automated switching of the first clamping part 50 between the clamping and releasing positions is achieved. This automated control reduces the need for manual intervention and improves the production efficiency and automation level of the stacking device 100. The clamping drive assembly 140 can precisely control the position and force of the first clamping part 50 according to a preset program or signal, ensuring that the stacked pieces 300 receive uniform and stable pressure during the clamping process. This helps improve the stability and consistency of the stacked pieces 300 and reduces quality problems caused by uneven clamping. The addition of the clamping drive assembly 140 reduces the risk of safety accidents caused by improper manual operation. By precisely controlling the movement trajectory and force of the first clamping part 50, equipment failure or damage to the stacked plates 300 caused by over-clamping or under-clamping can be avoided, thereby improving the safety and reliability of the equipment.

[0058] It should be noted that the type of clamping drive assembly 140 can be selected as needed. For example, the clamping drive assembly 140 may include a cylinder, a hydraulic cylinder, an electric actuator, a linear motor, or a ball screw, etc. Specifically, this application does not limit this.

[0059] Reference Figure 2 In one embodiment, the blowing unit 40 includes two air-blowing knives 41 spaced apart along a first direction. Each air-blowing knife 41 is adapted to blow air onto another stack 21 adjacent to the stack 21 where the stack 300 is located. Thus, the blowing action of the air-blowing knives 41 helps guide the material to the target stack 21, achieving rapid and accurate distribution of the material strip 200, reducing the need for manual intervention, improving production efficiency, and ensuring the consistency and accuracy of material strip 200 distribution. Furthermore, the design of the air-blowing knives 41 reduces the entanglement and blockage of the material strip 200 in the stacking device 100. This helps maintain continuous operation of the production line and reduces production interruptions or malfunctions caused by material strip 200 problems. The two air-blowing knives 41 spaced apart along the first direction make full use of the space in the stacking device 100, avoid mutual interference between the air knives, and also provide more space for the installation and operation of other components. This optimized layout helps improve the overall operating efficiency and reliability of the stacking device 100. Since each air-blowing knife 41 can independently blow air to the adjacent stacking platform 21, different air-blowing knives can be selected to work according to actual production needs, thereby flexibly adjusting the air-blowing direction of the air knife and improving the adaptability and versatility of the stacking device 100.

[0060] Continue to refer to Figure 2 and Figure 5 , Figure 5 yes Figure 1 The diagram shows a partially enlarged view of the blowing section 40, the second pressing section 60, and the cutting assembly 110. In some embodiments, the airflow direction of the blowing air knife 41 has an angle θ with the normal of the bearing surface 211 of the corresponding stack 21, where 30°≤θ<90°. This design allows the airflow to act on the strip 200 at a certain angle, ensuring that the unstacked strip 200 is accurately guided to the other bearing surface 211. The angle θ between the airflow direction of the blowing air knife 41 and the normal of the bearing surface 211 of the corresponding stack 21 satisfies 30°≤θ<90°, causing the airflow to act on the strip 200 at an angle. The force of the airflow has horizontal and vertical components. The horizontal component guides the unstacked strip 200 to move towards the other bearing surface 211, while the vertical component allows the unstacked strip 200 to lie flat on the other bearing surface 211, thereby improving the quality of the stack 300 formed on the other bearing surface 211. In addition, since the force of the airflow blown out by the air knife 41 is a component force in both the horizontal and directional directions, the direct impact force of the airflow on the stack 300 is reduced, thus protecting the stability and integrity of the stack 300.

[0061] It should be noted that the angle between the direction of the airflow blown by the air knife 41 and the normal to the bearing surface 211 of the corresponding stack 21 can be set as needed. For example, the angle between the direction of the airflow blown by the air knife 41 and the normal to the bearing surface 211 of the corresponding stack 21 can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, or 85°, etc. Specifically, this application does not limit the size of the angle between the direction of the airflow blown by the air knife 41 and the normal to the bearing surface 211 of the corresponding stack 21.

[0062] Furthermore, if the airflow direction forms a 90° angle with the normal of the bearing surface 211 of the corresponding stack 21, the airflow direction is parallel to the bearing surface 211 and may cause excessive direct impact on the stack 300, leading to displacement or damage to the stack 300. When the airflow direction forms an angle of less than 30° with the normal of the bearing surface 211 of the stack 21, the force of the airflow guiding the unstacked material strip 200 to be laid on another bearing surface 211 is too small, which exacerbates the adhesion or jamming problem between the unstacked material strip 200 and the stack 300.

[0063] In some embodiments, the stacking device 100 further includes a second clamping part 60, which is adapted to be movably mounted on the base 10 between a clamping position and a releasing position along the normal extension direction of the bearing surface 211. In the clamping position, the second clamping part 60 is used to clamp the unstacked strip 200 at a position adjacent to the stack 300. In the releasing position, the second clamping part 60 is used to release the strip 200. Thus, in the clamping position, the second clamping part 60 can clamp the unstacked strip 200 at a position adjacent to the stack 300. On the one hand, this can prevent the stack 300 formed by stacking on one bearing surface 211 from shifting. On the other hand, it can keep the strip 200 stable during the stacking process on another bearing surface 211, reducing the stacking error caused by the movement or offset of the strip 200. This design significantly improves the accuracy and quality of the stack 300 formed by stacking on another bearing surface 211, meeting the requirements of high-precision production. The second clamping part 60 can quickly switch to the clamping position when needed to clamp the material belt 200, and switch to the loosening position when not needed to loosen the material belt 200. This flexible operation helps to optimize the production process, reduce unnecessary waiting time, and improve production efficiency.

[0064] It should be noted that the specific shape of the second clamping part 60 can be selected as needed, but this application does not limit it.

[0065] In one embodiment, each air-blowing knife 41 is provided with a corresponding second clamping part 60. The stacking device 100 also includes a mounting frame 70. Each air-blowing knife 41 and the corresponding second clamping part 60 are integrated into one unit via the mounting frame 70. The mounting frame 70 is adapted to be movably mounted on the base 10 along the normal extension direction of the bearing surface 211. Thus, by integrating each air-blowing knife 41 and the corresponding second clamping part 60 onto the mounting frame 70, this integrated design makes the overall structure of the stacking device 100 more compact, helping to save the floor space occupied by the stacking device 100 and improve space utilization. The integrated design of the air-blowing knife 41 and the second clamping part 60 allows them to work more closely together. The air knife 41 guides the unstacked strip 200 while the second pressing part 60 can quickly press the strip 200, ensuring that the tail piece of the formed stack 300 does not move and the first piece of the newly formed stack 300 does not move, thereby improving the quality of the stack 300 formed on the two adjacent bearing surfaces 211.

[0066] Furthermore, the integrated design simplifies the installation and maintenance process of the air-blowing knife 41 and the second clamping unit 60. Operators can install or remove both simultaneously using a single mounting bracket 70, reducing operating steps and time. At the same time, the high degree of component integration also facilitates overall debugging and troubleshooting.

[0067] Reference Figure 2In some embodiments, the second clamping part 60 has a clamping end face for abutting against the material strip 200. The distance between the clamping end face and the air-blowing knife 41 along the normal extension direction of the bearing surface 211 is L, where 50mm ≤ L ≤ 200mm. Thus, by limiting the distance between the clamping end face and the air-blowing knife 41 to the range of 50mm to 200mm, the clamping end face physically clamps the material strip 200, while the air-blowing knife 41 guides the un-overlapped material strip 200 precisely onto the other bearing surface 211 via airflow.

[0068] Furthermore, when the distance between the pressing end face and the air-blowing knife 41 is less than 50mm, the airflow from the air-blowing knife 41 exerts excessive force on the unstacked strip 200, causing deformation or damage to the unstacked strip 200 or displacement of the stacked sheets 300. When the distance between the pressing end face and the air-blowing knife 41 is greater than 200mm, the airflow from the air-blowing knife 41 exerts insufficient force on the unstacked strip 200, preventing the unstacked strip 200 from being accurately laid on the other bearing surface 211.

[0069] It should be noted that the distance between the clamping end face and the air blowing knife 41 can be selected as needed. For example, the distance between the clamping end face and the air blowing knife 41 can be 50mm, 60mm, 70mm, 85mm, 90mm, 100mm, 115mm, 120mm, 135mm, 145mm, 150mm, 168mm, 175mm, 188mm, 190mm, or 200mm, etc. Specifically, this application does not limit the distance between the clamping end face and the air blowing knife 41.

[0070] In some embodiments, the stacking device 100 further includes a first linear drive assembly 80, which is mounted on the base 10 and drivenly connected to the second clamping part 60. The first linear drive assembly 80 drives the second clamping part 60 to move. Thus, through the drive connection between the first linear drive assembly 80 and the second clamping part 60, the stacking device 100 can achieve precise control over the movement of the second clamping part 60. The first linear drive assembly 80 can automatically drive the second clamping part 60 to switch between a clamping position and a releasing position according to a preset program or signal, without manual intervention, thus improving the automation level of the stacking device 100. The rapid response and precise control capability of the first linear drive assembly 80 enable the second clamping part 60 to complete the clamping and releasing actions in a short time, thereby improving the production efficiency of the stacking device 100. Simultaneously, due to the stability and repeatability of the driving process, production fluctuations caused by human factors are reduced, improving the stability of the stacked product quality. Because the first linear drive assembly 80 automates the drive of the second clamping part 60, operators no longer need to manually operate the second clamping part 60, reducing operational difficulty and labor intensity. At the same time, this also reduces the risk of equipment malfunctions or production accidents caused by improper human operation.

[0071] It should be noted that the type of the first linear drive assembly 80 can be selected as needed. For example, the first linear drive assembly 80 may include a cylinder, a hydraulic cylinder, an electric actuator, a linear motor, or a ball screw, etc. Specifically, this application does not limit this.

[0072] In some embodiments, a limiting portion 90 is provided on the adjacent side of each of two adjacent stacks 21. Each limiting portion 90 is adapted to be movably mounted on the base 10 between a limiting position and a clearance position along the normal extension direction of the bearing surface 211. In the limiting position, the limiting portion 90 protrudes from the bearing surface 211 to abut against the end of the stack 300 on the bearing surface 211 adjacent to another stack 21. Thus, the limiting portion 90 provides a precise positioning reference for the stack 300, which helps ensure that the stack 300 maintains the correct position and orientation during stacking, improves the alignment accuracy of the stack 300, and reduces quality problems caused by misalignment of the stack 300. In addition, the limiting portion 90 provides stable support and guidance during stacking, reducing swaying and offset during the stacking process, thereby improving the stability and production efficiency of the stack 300. In the clearance position, the limiting portion 90 is lower than or flush with the bearing surface 211. In this way, the limiting part 90 is lower than or flush with the bearing surface 211, ensuring that the unstacked material strip 200 can be blown by the blowing part 40 to be laid on another bearing surface 211, thus avoiding interference or collision between the unstacked material strip 200 and the limiting part 90.

[0073] It should be noted that the stacking device 100 also includes a second linear drive assembly 130. Each limiting part 90 is correspondingly provided with a second linear drive assembly 130. The second linear drive assembly 130 is mounted on the base 10 and is drivenly connected to the corresponding limiting part 90. The second linear drive assembly 130 is used to drive the corresponding limiting part 90 to move. In this way, by providing a second linear drive assembly 130 for each limiting part 90, the stacking device 100 can achieve automated and precise control of the movement of the limiting part 90. The second linear drive assembly 130 can automatically drive the limiting part 90 to switch between the limiting position and the avoidance position according to a preset program or signal, without manual intervention, thereby improving the automation level and production efficiency of the stacking device 100. At the same time, due to the precision of the driving process, the stability and accuracy of the limiting part 90 during the movement are also ensured. By automating the movement of the limiting part 90, the second linear drive assembly 130 simplifies the operation and maintenance process of the stacking device 100. Operators no longer need to manually adjust the position of the limit part 90, which reduces the difficulty of operation and labor intensity.

[0074] It should be noted that the type of the second linear drive assembly 130 can be selected as needed. For example, the second linear drive assembly 130 may include a cylinder, a hydraulic cylinder, an electric actuator, a linear motor, or a ball screw, etc. Specifically, this application does not limit this.

[0075] In some embodiments, the stacking device 100 further includes a cutting component 110, which is mounted on the base 10. The cutting component 110 cuts the unstacked strip 200 at a position adjacent to the stacked sheets 300. In this way, the two stacked sheets 300 formed by two adjacent bearing surfaces 211 are cut and separated, which facilitates the subsequent processing of the stacked sheets 300.

[0076] It should be noted that the type of cutting component 110 can be selected as needed. For example, in some embodiments, the cutting component 110 includes a cutting blade. In another embodiment, the cutting component 110 includes a heating wire. There are various types of heating wires; for example, heating may include iron-chromium-aluminum alloy heating wire, nickel-chromium alloy heating wire, or molybdenum wire, etc. Specifically, this application does not limit this.

[0077] Reference Figure 2 In some embodiments, two cutting components 110, two second clamping parts 60, and two air venting knives are provided, and all three are integrated into one unit via a mounting bracket 70. This makes the stacking device 100 more compact and reduces its space occupation. Furthermore, this design allows the stacking device 100 to process two adjacent bearing surfaces 211 separately, thereby meeting different needs.

[0078] In some embodiments, the carrier 20 is movably mounted on the base 10 along a first direction, such that one of the at least two stacks 21 is aligned with the unloading assembly 30. Thus, the carrier 20 can move along the first direction on the base 10, allowing one of the at least two stacks 21 to be aligned with the unloading assembly 30. This facilitates the unloading assembly 30's delivery of the strip 200 to the aligned stack 21, reducing offset and error of the strip 200 during transport. This precise alignment control helps ensure that the strip 200 is accurately delivered to the stack 21, thereby improving the quality and consistency of the stacked sheets 300 and reducing the defect rate due to inaccurate alignment.

[0079] In one embodiment, the stacking device 100 further includes a transverse drive mechanism 120, which is mounted on the base 10 and drivenly connected to the support unit 20. The transverse drive mechanism 120 drives the support unit 20 to move. Thus, the transverse drive mechanism 120 provides a power source for the support unit 20, enabling it to move precisely on the base 10 according to a preset trajectory and speed. This precise movement is crucial for the stacking device 100 because it ensures that the stacking table 21 is accurately aligned with the unloading assembly 30, thereby improving the accuracy and production quality of the stacking 300. The addition of the transverse drive mechanism 120 enables the stacking device 100 to achieve automated production, reducing the need for manual intervention and adjustments. Through a preset program or signal, the transverse drive mechanism 120 can automatically drive the support unit 20 to a designated position, thereby accelerating production speed and improving production efficiency.

[0080] It should be noted that the type of transverse drive mechanism 120 can be selected as needed. For example, the transverse drive mechanism 120 may include a cylinder, a hydraulic cylinder, an electric actuator, a linear motor, or a ball screw, etc. Specifically, this application does not limit it in this regard.
