Description

Technical Field

[0001] This invention belongs to the field of stacking machine technology, specifically relating to a stacking machine for high-efficiency stacking of copper and steel sheets. Background Technology

[0002] Stacking machines are core equipment in lithium battery production. They stack positive and negative electrode sheets and separators into cells through high-precision automated operations, which directly affects the performance and safety of the battery. Currently, the mainstream technologies include traditional dual-station, new-type, and integrated cutting and stacking machines. Among them, the new-type stacking machine has become the industry trend due to its efficiency and precision advantages.

[0003] In existing stacking machines, after the stacking operation is completed, the stacked plates are conveyed and unloaded through a conveying structure. Since the different plates are only held together by gravity, the friction between the plates is insufficient to keep them stationary during the conveying and unloading process. This can easily lead to relative displacement between the plates, causing the entire plate to tilt and misalign, resulting in low stacking quality and making subsequent processing inconvenient.

[0004] Therefore, a stacking machine for high-efficiency stacking of copper and steel sheets is proposed. Summary of the Invention

[0005] This invention provides a stacking machine for high-efficiency stacking of copper and steel sheets, the purpose of which is to solve the problems mentioned above.

[0006] This invention provides a stacking machine for high-efficiency stacking of copper and steel sheets, comprising a frame. From left to right, the frame is arranged with workstations 1, 2, 3, a stacking workstation, 5, 6, and 7. A moving platform is positioned above the stacking workstation on the frame. A dual-workstation fixture is mounted on the moving end of the moving platform. The bottom of the dual-workstation fixture is equipped with a negative pressure suction cup for adsorbing the sheet metal. Seven lifting mechanisms are installed inside the frame, and the moving ends of these seven lifting mechanisms are respectively connected to workstations 1, 2, 3, 4, 5, 6, and 7. The outer walls of stations three, five, six, and seven are fixedly connected. An electrical control box is installed on one outer wall of the frame. A removal frame is installed on one side of the stacking station. A transfer frame is installed on the frame near the lower part of the stacking station. A material unloading guide assembly is installed on the frame. The material unloading guide assembly includes a vertical moving platform that slides on the inner side wall of the frame. An upper guide post and a lower guide post are installed on one outer wall of the vertical moving platform. The upper guide post is located above the lower guide post, and limit components are installed on the upper and lower guide posts.

[0007] Furthermore, the unloading guide assembly also includes a fixed frame located on the inner side wall of the frame near the lower part of the vertical moving platform. An electric push rod is provided on the outer wall of the fixed frame away from the vertical moving platform. The electric push rod is fixedly connected to a horizontal moving platform through its output end on one side. An inclined surface is provided on one side of the top of the horizontal moving platform, and an inclined surface is provided on one side of the bottom of the vertical moving platform. Grooves are provided on the outer side wall of the frame near the outer side of the upper guide column and the lower guide column.

[0008] Furthermore, the limiting component includes a column sleeve that is movably fitted onto the outer walls of the upper guide post and the lower guide post. A fixing plate is provided on the outer circumferential surface of the column sleeve. An electric push rod two is provided on one side of the outer wall of the fixing plate near the column sleeve. The electric push rod two is fixedly connected to the limiting plate one through its output end.

[0009] Furthermore, the two ends of the first limiting plate are rotatably connected to the second limiting plate, which is mirror image of the first limiting plate. A toothed disc is provided at the middle position of one side of the second limiting plate. An electric push rod is provided at the center of the outer wall of the first limiting plate facing the fixed plate. The electric push rod is fixedly connected to a movable frame through its output end. A movable plate is slidably connected to the outer wall of the first limiting plate near the electric push rod. A toothed groove is provided on the outer wall of the movable plate facing the toothed disc. A linkage plate is movably provided between the movable plate and the movable frame. A through hole is provided at the center of the outer wall of the fixed plate facing the electric push rod. An upper pressure plate is provided on the top of the first limiting plate.

[0010] Furthermore, steel sheets, copper sheets, steel sheets, copper sheets, and steel sheets are placed sequentially on the top of each of the workstations 1, 2, 3, 5, 6, and 7. By adopting the above technical solution, steel sheets and copper sheets are manually placed into the corresponding machine positions to assist the equipment in confirming that the incoming materials are neat and meet the stacking requirements. When performing the stacking operation, the gripping sequence of the dual stations is station one and station two, station two and station three, station five and station six, and station six and station seven. After gripping the corresponding steel sheets and copper sheets, the single-layer stacking sequence is 1-2-3-2-5-6-7-6 (i.e., steel sheet, copper sheet, steel sheet, copper sheet, steel sheet, copper sheet, steel sheet).

[0011] Furthermore, the dual-station fixture is equipped with a pneumatic device that provides negative pressure suction for the negative pressure suction cup. The pneumatic device includes a high-pressure air pump and an air pipe for connection. By adopting the above technical solution, the negative pressure suction cup is provided with negative pressure suction force under the action of the high-pressure air pump, thereby lifting the board and making it easier to move the board to achieve the purpose of subsequent stacking.

[0012] Furthermore, the lifting mechanism includes a servo motor, the output end of which is fixedly connected to a trapezoidal lead screw. Station 1, Station 2, Station 3, Stacking Station, Station 5, Station 6 and Station 7 are fixedly connected to the screw nut seat on the trapezoidal lead screw, and Station 1, Station 2, Station 3, Stacking Station, Station 5, Station 6 and Station 7 are slidably connected to the frame. By adopting the above technical solution, a servo motor drives a trapezoidal screw to rotate through its output end on one side. The trapezoidal screw pulls the lifting and lowering of station 1, station 2, station 3, stacking station, station 5, station 6 and station 7 to achieve the purpose of feeding materials. This facilitates the stacking operation after the board is adsorbed. The stability of the lifting and lowering movement of station 1, station 2, station 3, stacking station, station 5, station 6 and station 7 is ensured by sliding connection.

[0013] Furthermore, the horizontal moving platform and the fixed frame are slidably connected, the first inclined plane and the second inclined plane are parallel, and the upper guide column and the lower guide column can move up and down within the slot; By adopting the above technical solution, under the inclined guidance of inclined plane one and inclined plane two, the vertical moving platform can be pushed to rise and fall vertically during the horizontal movement of the horizontal moving platform, thereby adjusting the height of the vertical moving platform. The upper guide column and the lower guide column are adjusted in height simultaneously, thereby realizing the adjustment of the overall height of the limiting component, so that the limiting component can be limited and docked with the stacked product.

[0014] Furthermore, the toothed disc and the toothed groove are connected by meshing teeth, and the toothed disc has a notch, and the toothed disc is fixed to the limiting plate two through the notch, and one side wall of the limiting plate two is flat. By adopting the above technical solution, the meshing transmission can pull the second limiting plate to rotate when the movable plate moves linearly, thereby adjusting the angle between the second limiting plate and the first limiting plate, and making the second limiting plate and the first limiting plate perpendicular to each other. The second limiting plate is used to limit the steel plate and the copper plate, ensuring that the steel plate and the copper plate are stacked neatly. The specially designed toothed disc can avoid the phenomenon of the toothed disc contacting the steel plate and the copper plate during the rotation of the second limiting plate, and avoid the problem of the steel plate and copper plate being squeezed and the stacking not being neat.

[0015] Furthermore, both ends of the linkage plate are rotatably connected to the movable frame and one side of the movable plate, respectively; By adopting the above technical solution, the linkage plate between the movable frame and the movable plate changes angle, thereby using the movable frame to pull the movable plate to move linearly during the linear movement process.

[0016] The beneficial effects of this invention are as follows: This invention utilizes the cooperation of a feeding guide component and a limiting component. The limiting component can limit the stacked products in the horizontal, vertical, and transverse directions, preventing relative displacement of the copper and steel plates due to insufficient friction or mechanical shaking during the feeding and conveying process. The feeding guide component ensures that the steel and copper plates remain in a limited state during the feeding and conveying process, guaranteeing the neatness of the stacked steel and copper plates after feeding and improving product quality.

The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Reference Figure 1-4This invention proposes a stacking machine for high-efficiency stacking of copper and steel sheets, comprising a frame 1. From left to right, the frame 1 has four stations: station 11, station 2, station 3, stacking station 14, station 5, station 6, and station 7. A moving platform 2 is positioned above the stacking station 14 on the frame 1. A dual-station fixture 21 is mounted on the moving end of the moving platform 2. A negative pressure suction cup 22 for adsorbing the sheet metal is mounted at the bottom of the dual-station fixture 21. A pneumatic device is mounted on the dual-station fixture 21 to provide negative pressure suction for the negative pressure suction cup 22. The pneumatic device includes a high-pressure air pump and connecting air pipes. Under the action of the high-pressure air pump, a negative pressure attraction force is provided for the negative pressure suction cup 22 to adsorb the sheet metal, thereby stacking the sheet metal... The material is lifted to facilitate the movement of the sheet metal for subsequent stacking. The machine frame 1 is internally equipped with seven lifting mechanisms 3. The moving ends of the seven lifting mechanisms 3 are fixedly connected to the outer walls of workstations 11, 12, 13, 14, 15, 16, and 17, respectively. Each lifting mechanism 3 includes a servo motor, the output end of which is fixedly connected to a trapezoidal lead screw. Workstations 11, 12, 13, 14, 15, 16, and 17 are fixedly connected to the screw and nut seats on the trapezoidal lead screw, and these workstations slide against the machine frame 1, utilizing the servo motor. The trapezoidal screw is driven to rotate through the output end on one side, which in turn pulls the lifting and lowering of stations 11, 12, 13, 14, 15, 16, and 17 to achieve the purpose of feeding materials. This facilitates the stacking operation after the sheet metal is adsorbed. The stability of the lifting and lowering movement of stations 11, 12, 13, 14, 15, 16, and 17 is ensured by a sliding connection. Steel sheets, copper sheets, steel sheets, copper sheets, and steel sheets are placed sequentially on the top of stations 11, 12, 13, 15, 16, and 17. The steel sheets and copper sheets are manually placed into the corresponding positions on the machine, assisting the equipment in determining the incoming materials. The stacking operation is performed in accordance with the requirements of stacking. The gripping sequence of the dual stations is station 11 and station 22, station 22 and station 33, station 515 and station 616, and station 616 and station 717. After gripping the corresponding steel sheet and copper sheet, the single-layer stacking sequence is 1-2-3-2-5-6-7-6 (i.e., steel sheet, copper sheet, steel sheet, copper sheet, steel sheet, copper sheet, steel sheet). An electrical control box 4 is installed on one side of the outer wall of the frame 1. A removal rack 5 is installed on one side of the stacking station 14. A transfer rack 6 is installed on the frame 1 near the lower position of the stacking station 14. A conveying mechanism is installed on the top of both the removal rack 5 and the transfer rack 6. The stacking station 14 is located at the conveying position of the conveying mechanism. A material unloading guide assembly 7 is installed on the frame 1. The unloading guide assembly 7 includes a vertical moving stage 76 that slides on the inner wall of the frame 1. An upper guide post 74 and a lower guide post 75 are provided on one outer wall of the vertical moving stage 76. The upper guide post 74 is located above the lower guide post 75, and a limit assembly 8 is provided on the upper guide post 74 and the lower guide post 75. The upper guide post 74 and the lower guide post 75 can not only support the limit assembly 8, but also guide the limit assembly 8 horizontally, so that the limit assembly 8 can move linearly along the upper guide post 74 and the lower guide post 75, thereby moving out of the stacking station 14 with the stacked products, and thus limiting the stacked products during the movement process to avoid misalignment of the steel plates and copper plates in the products during the unloading process. The unloading guide assembly 7 also includes a fixed frame 71 located on the inner side wall of the frame 1 near the lower part of the vertical moving platform 76. An electric push rod 711 is mounted on the outer wall of the fixed frame 71 on the side away from the vertical moving platform 76. The electric push rod 711 is fixedly connected to a horizontal moving platform 72 via its output end. A first inclined surface 721 is formed on one side of the top of the horizontal moving platform 72, and a second inclined surface 761 is formed on one side of the bottom of the vertical moving platform 76. The horizontal moving platform 72 and the fixed frame 71 are slidably connected, with the first inclined surface 721 and the second inclined surface 761 parallel to each other. The column 74 and the lower guide column 75 can move up and down within the slot 73. Under the inclined guidance of the first inclined surface 721 and the second inclined surface 761, the vertical moving platform 76 can be pushed up and down vertically during the horizontal movement of the horizontal moving platform 72, thereby adjusting the height of the vertical moving platform 76. The upper guide column 74 and the lower guide column 75 are adjusted in height simultaneously, thereby realizing the adjustment of the overall height of the limiting component 8 so that the limiting component 8 can be limited and docked with the stacked product. The outer side wall of the frame 1 is provided with slots 73 near the outer side of the upper guide column 74 and the lower guide column 75. The limiting assembly 8 includes a sleeve 81 movably fitted onto the outer walls of the upper guide post 74 and the lower guide post 75. A fixing plate 82 is provided on the outer circumferential surface of the sleeve 81. An electric push rod 821 is provided on one side of the outer wall of the fixing plate 82 near the sleeve 81. The electric push rod 821 is fixedly connected to a limiting plate 83 via its output end. Both sides of the limiting plate 83 are rotatably connected to a limiting plate 84. A gear plate 841 is provided on one side of the limiting plate 84 near the center. The limiting plate 83 faces the fixing plate 84. An electric push rod 3 85 is located at the center of one side of the outer wall of the fixed plate 82. The electric push rod 3 85 is fixedly connected to a movable frame 86 via its output end. A movable plate 87 is slidably connected to one side of the outer wall of the limiting plate 1 83 near the electric push rod 3 85. A toothed groove 871 is formed on the outer wall of the movable plate 87 facing the gear disc 841. The gear disc 841 and the toothed groove 871 are connected by meshing gear teeth. The gear disc 841 has a notch, and the gear disc 841 is fixed to the limiting plate 2 84 through the notch. The limiting plate 2 84... One side wall is flat. Using meshing transmission, the movable plate 87 can pull the second limiting plate 84 to rotate during linear movement, thereby adjusting the angle between the second limiting plate 84 and the first limiting plate 83, ensuring they are perpendicular. The second limiting plate 84 limits the steel and copper plates, ensuring they are stacked neatly. The specially designed toothed disc 841 prevents contact between the second limiting plate 84 and the steel and copper plates during rotation, thus avoiding squeezing the plates. To address the issue of unevenly stacked pieces, a linkage plate 88 is movably installed between the movable plate 87 and the movable frame 86. The two ends of the linkage plate 88 are rotatably connected to one side of the movable frame 86 and the movable plate 87, respectively, allowing the linkage plate 88 between the movable frame 86 and the movable plate 87 to change angles. This allows the movable frame 86 to pull the movable plate 87 to move linearly during the linear movement process. A through hole 822 is provided at the center of the outer wall of the fixed plate 82 facing the electric push rod 85. An upper pressure plate 89 is provided on the top of the limiting plate 83. To ensure the neatness of the multi-layered steel and copper plates after stacking during the unloading process and to prevent misalignment caused by relative displacement, this embodiment utilizes the cooperation of the unloading guide component 7 and the limiting component 8. The limiting component 8 can limit the stacked product in the horizontal, vertical, and transverse directions, preventing relative displacement caused by insufficient friction or mechanical shaking during the unloading and conveying process. The unloading guide component 7 keeps the steel and copper plates in a limited position throughout the unloading and conveying process, ensuring the neatness of the stacked steel and copper plates and improving product quality. Specifically, during the stacking operation, workers place the steel and copper plates into the corresponding machine positions. During the placement of the steel and copper plates, the steel... Plates, copper plates, steel plates, copper plates, steel plates, copper plates, and steel plates are placed sequentially on top of workstations 11 and 22, 22 and 33, 515 and 616, and 616 and 717. The moving platform 2 controls the movement of the dual-station fixture 21, causing it to move above workstations 11, 22, 313, stacking workstations 14, 515, 616, and 717. Once the dual-station fixture 21 has moved horizontally to the designated position (above workstations 11 and 22, above workstations 22 and 33, above workstations 515 and 616, and above workstations 616 and 717), the lifting mechanism 3 then controls the movement. The workstation at the designated position moves vertically upward. At this time, the negative pressure suction cup 22 adsorbs the copper and steel plates on the workstation. After the adsorption of the copper and steel plates is completed, they are placed on top of the stacking workstation 14 in sequence. Multiple layers of copper and steel plates are stacked on the stacking workstation 14. After the stacking is completed, the control electric push rod 711 drives the horizontal moving table 72 to move horizontally in a straight line through its output end on one side. As the horizontal moving table 72 moves, the horizontal moving table 72 gradually separates from the vertical moving table 76. When the vertical moving table 76 loses its support, the vertical moving table 76 pulls the upper guide column 74 and the lower guide column 75 to move vertically downward. Under the limit of the slot 73, the upper guide column 74 and the lower guide column 75, carrying the limiting component 8, descend to the lowest point of the inner side wall of the slot 73. At this time, the upper pressure plate 89 presses against the top of the stacked product. Then, the electric push rod 821 is controlled to drive the limiting plate 83 to move horizontally through its output end. The limiting plate 83 abuts against the side walls of the copper plate and steel plate, using the two limiting plates 83 to limit the product behind the disc. Then, the electric push rod 85 is controlled to drive the movable frame 86 to move linearly through its output end. As the movable frame 86 moves, it pulls one end of the linkage plate 88. As the position of one end of the linkage plate 88 changes, the other end of the linkage plate 88 pulls the movable plate 87 to move linearly along the limiting plate 83. When the movable plate 87 moves, it engages with the gear plate 841 and the tooth groove 871, causing the movable plate 87 to rotate.At this time, the second limiting plate 84 rotates synchronously. During the rotation, the second limiting plate 84 moves to the other side of the steel plate and copper plate, using the second limiting plate 84 to limit the steel plate and copper plate in both horizontal and vertical directions. After completing the all-round limiting of the stacked product, the stacked product is transported by the conveying mechanism. Since the limiting component 8 is fixed to the product, under the horizontal guidance of the upper guide post 74 and the lower guide post 75, the stacked product moves together with the limiting component 8. The limiting component 8 remains in a limiting state throughout the product conveying and unloading process, preventing misalignment of the steel plate and copper plate in the product during unloading.
