Implementation

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] The following describes an embodiment of the present invention based on its overall structure. Example

[0021] like Figure 1 and 2 As shown, an integrated mechanism for producing square batteries includes an integrated welding conveying and flipping mechanism, which includes a lifting conveying chain 1 located on a conveying platform, and conveying limiting mechanisms are arranged on both sides of the top of the lifting conveying chain 1, and a flipping mechanism is arranged on the conveying limiting mechanism; the conveying limiting mechanism includes a limiting plate 2 arranged in a symmetrical structure, and the bottom of the limiting plate 2 is connected to the top of the conveying platform of the lifting conveying chain 1 through a fixing part, and each limiting plate 2 is connected to a conveying slide-in plate 3 below one side close to the lifting conveying chain 1, and the conveying slide-in plate 3 is perpendicular to the limiting plate 2, and each conveying slide-in plate 3 is provided with a slide-in slope at one end, and a conveying slide-out slope at the other end.

[0022] It should be noted that the present application sets a lifting conveyor chain 1 to facilitate the conveyance of square batteries. When the square batteries are conveyed to the welding area, the lifting conveyor chain 1 descends to place the square batteries on the support assembly for welding. After the welding is completed, the lifting conveyor chain 1 is lifted to convey the square batteries out, which is convenient to use and operate. The production line of the present application has a high degree of integration, a small footprint, low equipment cost, saves the process of back and forth conveying and flipping during welding, and has high production efficiency. After one side is welded, it is directly pushed in, flipped and pushed out to weld the other side, which saves the process of back and forth conveying and flipping, and ensures the accuracy of double-sided welding connection; Furthermore, by setting the electromagnetic push-in, push-out and clamping mode, the magnet can quickly and accurately locate the workpiece, thereby reducing errors and improving production efficiency. While having high stability, the magnetic attraction can eliminate internal stress and deformation, which helps to maintain the accuracy and shape of the workpiece outside the battery. It can be easily clamped and released without damaging the workpiece. Magnetic clamping can also help realize automated production lines without the need for human intervention. By controlling the current and voltage to accurately control the size of the clamping force, the accuracy of the position and posture of the clamped object during the processing can be guaranteed. Furthermore, the turning mechanism can be installed in an area with limited space, thereby improving space utilization.

[0023] like Figure 1 and 3As shown, the flip push assembly includes a first slide rail 6 and a first slider 61. The first slide rail 6 is located in parallel on one of the support plates 4 on the side away from the drive motor 5, and the first slider 61 is slidably located on the first slide rail 6; a first electromagnet 62 is arranged inside the first slider 61, and the first electromagnet 62 is connected to an external power supply mechanism through a wire; the flip push assembly includes a second slide rail 7 and a second slider 71. The second slide rail 7 is located in parallel on one of the support plates 4 on the side close to the drive motor 5, and the second slider 71 is slidably located on the second slide rail 7; a second electromagnet 72 is arranged inside the second slide rail 7, and the second electromagnet 72 is connected to an external power supply mechanism through a wire; the first slider 61 and the second slider 71 are both pasted with protective pads on the side close to the lifting conveyor chain 1, and the protective pads are detachable.

[0024] It should be noted that in this embodiment, by setting the electromagnetic magnetic push-in, push-out and clamping mode, the magnet can quickly and accurately locate the workpiece, thereby reducing errors and improving production efficiency. While having high stability, the magnetic attraction can eliminate internal stress and deformation, which helps to maintain the accuracy and shape of the workpiece outside the battery. It can be easily clamped and released without damaging the workpiece. Magnetic clamping can also help realize an automated production line without the need for manual intervention. By controlling the current and voltage to accurately control the size of the clamping force, the accuracy of the position and posture of the clamped object during the processing can be guaranteed. Furthermore, when welding on one side is completed and the other side needs to be flipped for welding, a detachable protective pad is attached to the first slider 61 and the second slider 71 close to the side of the lifting conveyor chain 1. The first slider 61 slides on the first slide rail 6, the first electromagnet 62 is not energized, and the second electromagnet 72 is energized to generate a magnetic field to attract the first slider 61 to move on the first slide rail 6 toward the second slider 71. When the first slider 61 moves, it pushes the square battery to move toward the second slider 71. At this time, the second electromagnet 72 attracts the clamping rod 8 to move toward the square battery, and the clamping rod 8 moves on the slide bar 81 while squeezing and resetting. The spring 82 is compressed, and the clamping rod 8 and the support plate 4 clamp the battery, and the driving assembly drives the flip. At this time, the second electromagnet 72 is not energized, and the first electromagnet 62 is energized to generate a magnetic field to attract the second slider 71 to move toward the side of the first slider 61 on the second slide rail 7. While the second slider 71 moves, it pushes the square battery to move toward the side of the first slider 61 to reset the square battery. At this time, the elastic force of the reset spring 82 pushes the clamping rod 8 to move away from the square battery, and the clamping rod 8 is reset. The other side is welded by the welding mechanism. After welding is completed, the lifting conveyor chain 1 is lifted to transport the square battery out.

[0025] like Figure 1 , 4As shown in 5, the flipping mechanism includes a supporting assembly, a driving assembly, a flip pushing assembly, a flip pushing assembly and a clamping assembly. The supporting assembly includes a supporting plate 4 arranged in an L-shaped structure. The supporting plates 4 are symmetrically distributed on the inner walls on both sides of the limiting plate 2, and the supporting plates 4 are fixed to the limiting plate 2 through a fixed shaft 41; the driving assembly includes a driving belt 51, a driving motor 5, a driving wheel 52 and a driven wheel 53. The driving motor 5 is located on the outer wall of one side of the limiting plate 2, and the output end of the driving motor 5 is fixedly connected to the driving wheel 52. The fixed shaft 41 passes through the limiting plate 2 and extends to the outside thereof. Fixedly connected to the driven wheel 53, the driven wheel 53 is connected to the driving wheel 52 through the driving belt 51.

[0026] It should be noted that, in the present embodiment, the support plate 4 is fixed to the limit plate 2 by a fixed shaft 41, and one end of the fixed shaft 41 is connected to the driven wheel 53. When the clamping rod 8 and the support plate 4 clamp the battery, the driving motor 5 rotates to further drive the active wheel 52 on its output end to rotate. The active wheel 52 is connected to the driven wheel 53 through a driving belt 51. While the active wheel 52 drives the driven wheel 53 to rotate, the fixed shaft 41 drives the support plate 4 to flip, and further flips the square battery. After the flipping is completed, the component is reset by flipping and pushing it out, and the other side is welded by a welding mechanism. The production line has a high degree of integration, a small footprint, and low equipment cost. It saves the process of back and forth conveying and flipping during welding, and has high production efficiency. After one side is welded, it is directly pushed in and flipped out to weld the other side, which saves the process of back and forth conveying and flipping, ensuring the accuracy of double-sided welding connection. The flipping mechanism can be installed in an area with limited space, thereby improving space utilization.

[0027] like Figure 3 and 4 As shown, the clamping assembly includes a clamping rod 8, a sliding rod 81 and a reset spring 82. The clamping rod 8 is located parallel to the top of the second slide rail 7. The support plate 4 is provided with a first groove 42 near the clamping rod 8. The sliding rod 81 is located inside the first groove 42. One end of the clamping rod 8 slides on the sliding rod 81 through a sliding sleeve. The reset spring 82 is sleeved on the outer circumferential wall of the sliding rod 81 below the clamping rod 8. The bottom of the reset spring 82 is connected to the inner wall of the first groove 42, and the top of the reset spring 82 is connected to the bottom of the sliding rod 81.

[0028] It should be noted that, in the present embodiment, when the second electromagnet 72 is energized to generate a magnetic field, the clamping rod 8 is attracted to move toward one side of the square battery. The clamping rod 8 moves on the slide bar 81 while squeezing the reset spring 82 to compress. At this time, the clamping rod 8 and the support plate 4 clamp the battery, and the driving assembly drives the flip. When the second electromagnet 72 is not powered on and the electromagnetic property disappears, the elastic force of the reset spring 82 pushes the clamping rod 8 to move to the side away from the square battery, and the clamping rod 8 is reset. The structure is simple and easy to operate. The clamping work can be completed without external drive. While the stability is high, the magnetic attraction can eliminate internal stress and deformation, which helps to maintain the accuracy and shape of the workpiece outside the battery. It can be easily clamped and released without damaging the workpiece. Magnetic clamping can also help realize an automated production line without manual intervention. The clamping force can be accurately controlled by controlling the current and voltage to ensure the accuracy of the position and posture of the clamped object during the processing.

[0029] The working principle of the present invention is: After the lifting conveyor chain 1 conveys the square battery to the welding area, the lifting conveyor chain 1 descends to place the square battery on the support assembly for one-side welding. When one side of the welding is completed and needs to be turned over for welding on the other side, the first slider 61 slides on the first slide rail 6, the first electromagnet 62 is not energized, and the second electromagnet 72 is energized to generate a magnetic field to attract the first slider 61 to move on the first slide rail 6 toward the second slider 71. While the first slider 61 moves, it pushes the square battery to move toward the second slider 71. At this time, the second electromagnet 72 attracts the clamping rod 8 to move toward the side of the square battery, and the clamping rod 8 is on the slide bar 81. While moving, the reset spring 82 is squeezed and compressed. At this time, the clamping rod 8 and the support plate 4 clamp the battery, and the driving motor 5 rotates to further drive the driving wheel 52 on its output end to rotate. The driving wheel 52 is connected to the driven wheel 53 through the driving belt 51. The driving wheel 52 drives the driven wheel 53 to rotate while the fixed shaft 41 drives the support plate 4 to flip, further flipping the square battery. At this time, the second electromagnet 72 is not energized, and the first electromagnet 62 is energized to generate a magnetic field to attract the second slider 71 to move toward the side of the first slider 61 on the second slide rail 7. The second slider 71 moves while pushing the square battery The battery is moved toward the side of the first slider 61 to reset the square battery. At this time, the elastic force of the reset spring 82 pushes the clamping rod 8 to move away from the square battery. The clamping rod 8 is reset and the other side is welded by the welding mechanism. After the welding is completed, the lifting conveyor chain 1 is lifted to transport the square battery out; the production line of the present application has a high degree of integration, a small footprint, and low equipment cost, which saves the process of back and forth conveying and flipping during welding, and has high production efficiency. After one side is welded, it is directly pushed in, flipped and pushed out to weld the other side, which saves the process of back and forth conveying and flipping, and ensures the accuracy of double-sided welding connection; by setting an electromagnetic The ferromagnetic push-in, push-out and clamping method allows magnets to quickly and accurately position workpieces, thereby reducing errors and improving production efficiency. While having high stability, the magnetic attraction force can eliminate internal stress and deformation, helping to maintain the accuracy and shape of workpieces outside the battery. It can be easily clamped and released without damaging the workpiece. Magnetic clamping can also help realize automated production lines without the need for human intervention. By controlling the current and voltage to precisely control the size of the clamping force, the accuracy of the position and posture of the clamped object during processing can be ensured; the flipping mechanism can be installed in areas with limited space, thereby improving space utilization.
