Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a battery tab pressing device. Background Art

[0002] Battery tabs are metal conductors that lead the positive and negative electrodes out of the battery cell and act as contact points during the charging and discharging process. During the battery production process, neatly arranged tabs are conducive to the operation of automated production lines. During the production process, machines can more easily identify and locate the tabs and perform precise welding or connection operations. If the tabs are arranged in a disorderly manner, it will not only increase the difficulty of production, but may also reduce production efficiency.

[0003] Therefore, during the battery production process, a tab pressing device is provided on the track to apply force to the tab from the outside to the inside, so that the outer sides of the tab are arranged neatly. However, the existing pressing device only applies force to the tab when working, and uses the gravity of the battery itself to ensure that the battery will not tilt after the tab is subjected to force. This method is suitable for batteries that are transported in the middle position of the conveyor track. When the position of the battery on the conveyor track is significantly offset (such as close to one side of the track), when force is applied to the tab, since the force point is located at the top of the battery and the movement distance of the mechanism that applies force to the tab is too long relative to the battery itself, the battery is prone to tilt, resulting in the inability to align the tab. Utility Model Content

[0004] The main purpose of the utility model is to provide a battery tab pressing device. When the pressure plate device applies force to the tab, two limit plates will clamp the two sides of the battery box, so that the battery box body is located in the middle position of the track. Therefore, when the pressure plate applies force to the tab, the battery box itself will not tilt, thereby ensuring that the tabs can be neatly arranged after being pressed.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A battery lug pressing device comprises a frame, linear drive devices are fixed on opposite sides of the frame, two groups of driving ends of the linear drive devices are arranged opposite to each other and fixed with pressure plate devices, the pressure plate device comprises a connecting plate connected to the driving end of the linear drive device, a limiting plate for applying force to the battery box body is arranged at the bottom of the connecting plate, and a pressure plate corresponding to the position of the battery lug is fixed on one side of the connecting plate.

[0007] Furthermore, at least one set of connecting rods is fixed in the frame body, through holes are formed on the connecting plates, and the connecting plates are slidably connected to the connecting rods through the through holes.

[0008] Furthermore, a limiting rod is fixed on the periphery of the connecting rod, and the diameter of the limiting rod is greater than the diameter of the through hole.

[0009] Furthermore, the limiting rod is located at the center of the connecting rod.

[0010] Furthermore, the linear drive device is a cylinder or a hydraulic cylinder.

[0011] Furthermore, the connecting plate, the limiting plate and the pressing plate are integrally formed.

[0012] Furthermore, a buffer device is provided on the side of the limiting plate in contact with the battery box body.

[0013] Furthermore, the buffer device includes a limiting groove opened on the limiting plate, a buffer plate is arranged in the limiting groove, one side of the buffer plate is located outside the limiting groove, and the other side of the buffer plate is connected to the limiting groove through at least one group of elastic members.

[0014] Furthermore, the elastic member is a spring.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] When the pressure plate device of the utility model applies force to the pole ear, the two limit plates will clamp the two sides of the battery box, so that the battery box body is located in the middle position of the track. Therefore, when the pressure plate applies force to the pole ear, the battery box itself will not tilt, thereby ensuring that the pole ear can be neatly arranged after being pressed.

[0017] The connecting rod of the utility model can guide the movement of the connecting plate, so that the moving path of the pressing plate device meets the requirements.

[0018] The diameter of the limit rod of the utility model is larger than the diameter of the through hole. After the two pressure plate devices move a specified distance, they will contact the limit rod, thereby limiting the maximum moving distance of the pressure plate devices and preventing the pole ear from deflecting to the other side due to the increase in the moving distance of the pressure plate devices.

[0019] The buffer plate of the utility model will first contact the side wall of the battery box, and as the pressure plate device moves further, the elastic member will be compressed, so that the buffer plate has a certain buffering performance, avoiding the limit plate directly clamping the battery box due to the lack of a buffer mechanism, which causes clamping marks on the side wall of the battery box.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-3 As shown, a battery tab pressing device comprises a frame 1, linear drive devices 2 are fixed on opposite sides of the frame 1, the linear drive devices 2 are air cylinders or hydraulic cylinders, driving ends of two groups of linear drive devices 2 are arranged opposite to each other and fixed with pressing plate devices 3, the pressing plate device 3 comprises a connecting plate 301 connected to the driving ends of the linear drive devices 2, a limiting plate 304 for applying force to the battery box body is arranged at the bottom of the connecting plate 301, a pressing plate 303 corresponding to the position of the battery tab is fixed on one side of the connecting plate 301, and the connecting plate 301, the limiting plate 304 and the pressing plate 303 are integrally formed.

[0026] In this embodiment, the frame 1 is fixed on the frame of the battery conveyor crawler, and the battery box is conveyed to the device via the crawler. At this time, the linear drive device 2 drives the pressing plate device 3 to move. In this process, Figure 2 and Figure 3 As shown, the two limit plates 304 will contact the sides of the battery box body, thereby clamping the box body from both sides of the battery box and making the battery box located in the middle of the track, and the movement of the pressure plate 303 will apply force to the offset pole ears, thereby arranging the pole ears of the battery neatly.

[0027] Among them, Figure 1 As shown, at least one set of connecting rods 5 is fixed in the frame 1. Figure 2 and Figure 3 As shown, a through hole 302 is opened on the connecting plate 301, and the connecting plate 301 is slidably connected to the connecting rod 5 through the through hole 302. Therefore, the connecting rod 5 can guide the movement of the connecting plate 301, so that the moving path of the pressure plate device 3 meets the requirements, and a limiting rod 6 is fixed on the periphery of the connecting rod 5, and the diameter of the limiting rod 6 is larger than the diameter of the through hole 302, and the limiting rod 6 is located at the center position of the connecting rod 5. Therefore, the two pressure plate devices 3 will contact the limiting rod 6 after moving a specified distance, thereby avoiding the pole ear from deflecting to the other side due to the increase in the moving distance of the pressure plate device 3.

[0028] Among them, Figure 3 As shown, a buffer device 7 is provided on the side where the limiting plate 304 contacts the battery box body, and the buffer device 7 includes a limiting groove 702 opened on the limiting plate 304, and a buffer plate 701 is provided in the limiting groove 702. One side of the buffer plate 701 is located outside the limiting groove 702, and the other side of the buffer plate 701 is connected to the limiting groove 702 through at least one group of elastic members 703. The elastic members 703 are springs. In the process of the pressure plate device 3 clamping the side wall of the battery box, the buffer plate 701 of the buffer device 7 will first contact the side wall of the battery box, and with the further movement of the pressure plate device 3, the elastic member 703 will be compressed, so that the buffer plate 701 has a certain buffering performance, thereby avoiding leaving clamping marks on the side wall of the battery box body due to the lack of a buffer mechanism when the limiting plate 304 directly clamps the battery box.

[0029] Working principle: first, fix the frame 1 on the frame of the battery conveyor crawler. When the battery box is conveyed to the device via the crawler, the linear drive device 2 drives the pressure plate device 3 to move. During this process, the buffer plate 701 of the buffer device 7 will first contact the side wall of the battery box, and as the pressure plate device 3 moves further, the elastic member 703 will be compressed, so that the buffer plate 701 has a certain buffering performance and clamps the battery box, and the pressure plate 303 will apply force to the offset pole ear on the top of the battery box, so that the pole ears of the battery are neatly arranged. Furthermore, during the movement of the pressure plate device 3, since the connecting plate 301 is slidably connected to the connecting rod 5 through the through hole 302, the connecting rod 5 can guide the movement of the connecting plate 301, so that the moving path of the pressure plate device 3 meets the requirements, and the diameter of the limit rod 6 is larger than the diameter of the through hole 302, and the limit rod 6 is located at the center position of the connecting rod 5. Therefore, the two pressure plate devices 3 will contact the limit rod 6 after moving a specified distance, thereby avoiding the pole ear from deflecting to the other side due to the increase in the moving distance of the pressure plate device 3.
