[0002] Vacuum injection is a commonly used method for injecting liquid into batteries. After the injection is completed, the batteries will be inspected and defective batteries with dents will be picked out. However, since the batteries cannot be repaired if they are dented after the sealing nails are inserted, the battery defect rate is very high. The existing inspection scheme only inspects the battery's external dimensions and cannot solve the problem of dented battery shells at the same time. Picking out defective batteries at the same time will affect the rhythm of the production line and increase production costs. Summary of the Invention

[0030] DETAILED DESCRIPTION

[0031] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.

[0032] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", "clockwise" and "counterclockwise" and the like to indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0033] refer to Figures 1 to 4 One embodiment of the present invention provides a battery convexity forming machine, comprising a support frame 1, a limiting module 2 and an inflation module 3, wherein a convexity forming position for placing the battery is provided at the center of the support frame 1; the limiting module 2 is arranged on the support frame 1 to fix the battery on the convexity forming position, and comprises a limiting member 21 and a limiting drive 22, the limiting member 21 is arranged on one side of the convexity forming position and is slidably connected to the support frame 1 to fix the battery on the convexity forming position; the limiting drive 22 is electrically connected to the limiting member 21 to drive the limiting member 21 to move toward the convexity forming position; the inflation module 3 is arranged above the convexity forming position and is fixedly connected to the support frame 1 to inflate the battery located in the convexity forming position.

[0034] Specifically, the battery is secured to the convex portion by the position limiting module 2, wherein the position limiting drive 22 drives the position limiting member 21 toward the battery convex portion until the battery is adjusted to within the dimensional range of the convex portion. The position limiting drive 22 includes a self-locking mechanism to prevent the convex dimensions from being out of tolerance due to excessive protrusion force during the convex formation process. The inflation module 3 charges the battery with positive pressure gas through the battery filling port, causing the battery casing, which was concave during vacuum filling, to re-convex due to the internal and external pressure differential, restoring its normal appearance. In this embodiment, the position limiting drive 22 is a pneumatic cylinder, an electric cylinder, an electric actuator, or a combination of a motor and a screw.

[0035] Further, refer to Figures 1 to 5 The support frame 1 is a rectangular parallelepiped, the limit member 21 is slidably connected to the top of the support frame 1, the limit drive 22 is set on the side of the support frame 1, and the top of the support frame 1 is also provided with a fixing plate 11, and the inflation module 3 is fixed to the support frame 1 through the fixing plate 11.

[0036] Specifically, the rectangular support frame 1 has six sides, a limiter 21 is provided inside one side of the top of the support frame 1, a limit drive 22 is provided on a side of the support frame 1 away from the convex position, the limit drive 22 is connected to the limiter 21 by transmission, and the limit drive 22 moves in the direction of the convex position so that the limiter 21 limits the position of the battery to the size range within the convex position. A fixing plate 11 is provided on the outside of one side of the top of the support frame 1, and the inflation module 3 is fixed to the support frame 1 by the fixing plate 11, so that the inflation module 3 remains stable during the pressing process. Secondly, a notch is also provided on one side of the top of the support frame 1, and the inflation end of the inflation module 3 passes through the notch and is sealed with the liquid injection port of the battery located in the convex position to charge the battery with positive pressure gas. Such a setting occupies a small space and has a compact structure, and greatly improves the yield rate of battery vacuum injection at a relatively low cost.

[0037] Further, refer to Figure 6 The inflation module 3 includes a pressing drive 31, an inflation tube 32, and a plugging head 33. The pressing drive 31 is fixed to the support frame 1 through the fixing plate 11. The plugging head 33 is connected to the battery air inlet located in the convex position. One end of the inflation tube 32 is connected to the pressing drive 31, and the other end of the inflation tube 32 is connected to the plugging head 33. Specifically, the inflation tube 32 passes through the notch, and the plugging head 33 at one end of the inflation tube 32 close to the convex position is arranged just above the liquid injection port of the battery located in the convex position. After the pressing drive 31 is started, it is pressed downward so that the plugging head 33 is sealed with the liquid injection port of the battery located in the convex position. Then, positive pressure gas is charged into the battery through the inflation tube 32, so that the shell that was concave during vacuum injection is re-convex under the action of the internal and external air pressure difference, and the normal appearance is restored.

[0038] In this embodiment, the pressing drive 31 is a pneumatic cylinder, an electric cylinder, an electric actuator, or a combination of a motor and a screw. The plugging head 33 shown is made of corrosion-resistant rubber with a hardness of A50-A60. When the plugging head 33 is positioned against the battery filling port, the downward pressure from the pressing drive forces it into contact with the battery filling port until it deforms and seals the battery filling port.

[0039] Further, refer to Figure 6 A drive connection block 34 is provided between the compression drive 31 and the inflation tube 32 to enable the compression drive 31 to be compressed downward. Specifically, the drive connection block 34 is a connection portion used to support the compression drive 31 in piston motion. When the compression drive 31 is compressed downward, it needs to repeatedly perform linear motion. The drive connection block 34 allows the top pressure of the compression drive 31 to be dispersed, so that the safety of use is effectively guaranteed. The compression drive 31 is indirectly mounted on the inflation tube 32 through the drive connection block 34, so that the compression drive 31 will not bend due to eccentricity, poor balance accuracy, etc., and the rod support bearing and rod seal will not wear. This greatly improves the performance of the compression drive 31 and extends the service life of the compression drive 31. In addition, due to the small size, high resistance to displacement, and high compressive strength of the drive connection block 34, the compression drive 31 can move more smoothly during repeated compression motions.

[0040] Further, refer to Figure 6 The inflation tube 32 is provided with an inflation port 35 for inflating the battery. Specifically, positive pressure gas is introduced into the battery through the inflation port 35, causing the battery shell, which has been dented due to the vacuum, to bulge again due to the pressure difference between the inside and outside of the battery shell, restoring its normal appearance. Positive pressure gas can be generated by a booster air pump, and the air outlet of the air pump is connected to the inflation port on the inflation tube 32. This positive pressure gas is introduced into the battery shell, causing the internal pressure of the battery to be greater than the pressure of the external environment, and the pressure force is used to restore the dented shell to its normal appearance.

[0041] Further, refer to Figure 6 The inflation module 3 further includes a flange 36, which is disposed at the lower end of the compression driver 31 to secure the compression driver 31 to the inflation tube 32. Specifically, the flange 36 is used to connect the shafts. There are two flanges 36, which are tightly connected by bolts. The drive connection block 34 is disposed between the two flanges 36, so that the compression driver 31 and the inflation tube 32 are fixedly connected while allowing piston movement.

[0042] Further, refer to Figures 3 to 5The limit module 2 also includes an adjustment screw 23, which is disposed on the limit member 21 to control the distance between the limit member 21 and the reference member. Specifically, the adjustment screw 23 is mounted on the limit member 21, and the bottom of the adjustment screw 23 is connected to the limit member 21. During installation and commissioning, the position of the adjustment screw 23 can be adjusted to control the distance that the limit driver 22 pushes the limit member 21 toward the protrusion forming position, thereby adjusting the distance between the limit member 21 and the protrusion forming position until the distance is adjusted to within an appropriate size range, thereby preventing excessive protrusion force during battery protrusion forming from causing battery displacement.

[0043] Further, refer to Figures 3 to 5 The position limiting module 2 also includes a guide rail slider 24, which is disposed between the position limiting member 21 and the support frame 1. The guide rail slider 24 enables the position limiting member 21 to move toward the protruding position via the guide rail. Specifically, the guide rail slider 24 serves as a transmission mechanism. The position limiting driver 22 drives the position limiting member 21 toward the battery protruding position. The position limiting member 21 is then moved back and forth in the protruding position via the guide rail slider 24. Due to the high rigidity and low friction coefficient of the guide rail slider 24, the power of the position limiting driver 22 is greatly reduced, ensuring the stability of the entire position limiting module 2.

[0044] In this embodiment, the limit member 21 is composed of an upper limit plate and a lower limit plate, wherein the side surface of the upper limit plate is transmission-connected to the limit drive 22. The lower limit plate is spaced apart from the upper limit plate, and the side surface of the lower limit plate is also transmission-connected to the limit drive 22, so that a track groove is formed between the lower limit plate and the upper limit plate. The track groove matches the outer surface of the guide rail slider 24, so that when the limit member 21 makes a reciprocating motion, it is slidably connected to the guide rail slider 24 through the track groove, reducing the friction between the limit member 21 and the guide rail slider, greatly saving the power of the limit drive 22, and ensuring the stability of the entire limit module 2.

[0045] On the other hand, an embodiment of the present invention provides a battery convexity device, referring to Figures 1 to 4 , including at least one battery convexity machine and a conveyor belt 4, which is arranged at the bottom end of the support frame 1. Specifically, the figure shows two battery convexity machines symmetrically arranged on the support frame 1, and the conveyor belt 4 is correspondingly provided with two convexity positions. The conveyor belt 4 passes through the interior of the support frame 1 and is arranged at the bottom end of the support frame 1. This arrangement can convexify two batteries at the same time, greatly improving production efficiency. In other embodiments, the conveyor belt can also be replaced with a placement rack with a convexity position.

[0046] In this embodiment, the illustrated battery convexity device is a dual-channel structure formed by two battery convexity machines. This arrangement can convexify two battery shells at the same time. In other embodiments, it can also be set as one battery convexity machine or multiple battery convexity machines to form a single-channel or multi-channel structure to meet different production requirements.

[0047] Further, refer to Figures 3 to 5 When there are at least two battery convexity machines, a reference plate 5 is positioned between each of the two battery convexity machines. The reference plate 5 is connected to the top of the support frame 1. Specifically, the reference plate 5 is a square baffle that separates the two convexity positions and cooperates with a stopper 22 to secure the battery at the convexity position. One end of the reference plate 5 is fixedly connected to the top of the support frame 1. During installation and commissioning, the position of the screw 23 can be adjusted to control the spacing between the stopper 21 and the reference plate 5. This arrangement ensures that the battery is accurately confined to the convexity position and that the two battery convexity machines are not affected when they are separated during operation. When the battery convexity device has a multi-channel structure, the number of reference plates 5 matches the dual-channel structure.

[0048] In this embodiment, two slide limit blocks are further provided at one end of the reference plate 5 close to the top of the support frame 1. The two slide limit blocks are respectively arranged on both sides of one end of the reference plate 5 close to the top of the support frame 1. The reference plate 5 and the two slide limit blocks are both fixed structures. This arrangement increases the stability of the reference plate.

[0049] Through the above technical solution, the battery convexing machine provided by the present invention fixes the battery at the convexing position through the limit module 2, wherein the limit drive 22 drives the limit member 21 to move in the direction of the battery convexing position until the position of the battery is adjusted to within the size range of the convexing position, thereby avoiding the convexing size deviation caused by excessive convexing force during the convexing process. The inflation module 3 charges the battery with positive pressure gas through the battery filling port, so that the shell that was concave during vacuum filling is re-convexed due to the internal and external pressure difference, restoring its normal appearance. In addition, the battery convexing machine provided by the present invention occupies a small space and has a compact structure, greatly improving the qualified rate of battery vacuum filling at a relatively low cost.
