Description

Technical Field

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

[0002] In the automated production of batteries, the tabs on the battery plate group may be skewed to varying degrees. Therefore, before battery casting and welding, the tabs need to be shaped.

[0003] In the prior art, a Chinese invention patent with the patent number ZL201310250682.7 discloses a tab shaping mechanism, which includes a first shaping frame, a second shaping frame, and a driving component for driving the first shaping frame and the second shaping frame to shape the tabs. The first shaping frame includes a first slider and a first shaping strip provided on the first slider. The second shaping frame includes a second slider and a second shaping strip provided on the second slider. The first shaping strip and the second shaping strip are arranged at intervals. The tab shaping mechanism further includes a fixed frame. Parallel optical axes are provided on the fixed frame and respectively penetrate through the first slider and the second slider. When the first slider and the second slider move along the optical axes, the first shaping strip and the second shaping strip act relatively. The driving component includes a roller, a driving member for driving the roller to lift, and a reset member provided on the optical axis. The top surfaces of the first slider and the second slider are provided with slopes that abut against the roller, and depressions are provided below the slopes.

[0004] This type of tab shaping mechanism often shapes the tabs from above the tabs through a top-down action. Once the skew degree of the tabs is large, this type of shaping mechanism is likely to directly press on the tabs, exacerbating the skew degree of the tabs or even causing damage to the tabs. Summary of the Utility Model

Detailed implementation manners

[0027] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0028] Example 1

[0029] As Figure 1 and 2As shown in the figure, this embodiment provides a battery tab shaping mechanism, which includes a first linear driving device 1 and a shaping frame 2 provided at the output end of the first linear driving device 1. Among them, the first linear driving device 1 can adopt devices such as air cylinders and electric cylinders. Generally, when the battery 3 is transported, it is in an upright state, that is, the tabs 31 face upward. In order to avoid damaging the tabs during the shaping operation, this shaping frame needs to perform the shaping operation by horizontal movement from the side of the tabs. Therefore, the output end of the first linear driving device 1 moves in the horizontal direction. The shaping frame 2 includes a connecting rod 21 and a plurality of shaping rods 22 provided on the same side of the connecting rod 21. One end of the shaping rod 22 facing away from the connecting rod 21 has a guiding structure that is narrower at the bottom and wider at the top, and narrower at the front and wider at the back. The number of shaping rods 22 is one more than the number of tabs 31 in a row. Thus, by driving the shaping frame 2 to move horizontally towards the tabs through the first linear driving device 1, each tab gradually fits between two adjacent shaping rods 22. Due to the guiding structure at the end of the shaping rod 22, when the shaping rod is inserted between adjacent tabs, its tip will first be inserted between the roots of adjacent tabs. Even if the tabs are skewed, the position of their roots is fixed due to the relatively fixed position of the electrode plate. Therefore, the distance between the roots of adjacent tabs is relatively fixed, and the tip of the shaping rod 22 can be smoothly inserted. As the shaping rod continues to be inserted, the width of the part of the shaping rod inserted between adjacent tabs gradually increases until it is the same as the distance between the roots of adjacent tabs, thereby shaping the tabs to a vertical state. It should be noted that the battery has two rows of tabs, and the positions of the two rows of tabs are staggered with each other. Therefore, it is impossible to complete the shaping work of the two rows of tabs with one shaping frame at one time. Therefore, two sets of the first linear driving device 1 and the shaping frame 2 are required to shape the two rows of tabs from both sides of the battery respectively.

[0030] If the two first linear devices are arranged on both sides of the battery, it will inevitably increase the occupation of the lateral space, which is not conducive to the simultaneous tab shaping of multiple batteries. Therefore, in this embodiment, the first linear driving device 1 can be arranged above the battery through the frame. At the same time, a connecting plate 23 is provided on the connecting rod 21, and the output end of the first linear driving device 1 is connected to the side of the connecting plate 23 facing the extending direction of the shaping rod 22. At this time, the shaping rod 22 is located below the linear driving device 1. And when the first linear driving device performs the extending action, the shaping rod moves away from the tabs. When the first linear driving device performs the contracting action, the shaping rod is inserted between the tabs. Since the tab shaping work of one battery needs to be completed by two sets of the first linear driving device and the shaping frame, and the two shaping frames need to perform opposite actions from both sides of the battery respectively. Therefore, the actions of the two first linear driving devices are opposite. If the two first linear driving devices are arranged back to back, it will also increase the occupation of the lateral space. Therefore, in this embodiment, the two first linear driving devices 1 are arranged side by side, and the action directions of their output ends are opposite. Correspondingly, the positions of the connecting plates 23 on the two shaping frames 2 are staggered with each other.

[0031] To ensure the stability of the operation of the shaping frame 2, two guiding holes are provided in the first linear driving device 1, and guiding rods 11 are respectively provided between the connecting plate 23 and the two guiding holes.

[0032] Embodiment 2

[0033] As Figures 3 - 6 shown, this embodiment provides a battery tab shaping device, which includes a plate group flattening mechanism and the tab shaping mechanism as described above. The plate group flattening mechanism includes a second linear driving device 4, a pressing plate 5 provided at the output end of the second linear driving device 4, and a plate group pressing frame 6 provided on the pressing plate 5. The first linear driving device 1 is provided on the pressing plate 5. Among them, the second linear driving device 4 can adopt devices such as a cylinder or an electric cylinder. Generally, the battery 3 is placed upright. Therefore, the second linear driving device 4 can be arranged above the battery 3 through the frame, with the output end facing downwards, and the plate group pressing frame 6 and the tab shaping mechanism are arranged on the lower side surface of the pressing plate 5. During operation: when the battery 3 is conveyed below, the second linear driving device 4 drives the pressing plate 5 to move downwards until the plate group pressing frame 6 presses on the plate group to press each plate in the plate group to the same height in the battery case. At the same time, since the tab shaping mechanism is arranged on the pressing plate 5, when the plate group pressing frame 6 reaches the proper position, the shaping frame 2 also reaches the corresponding position. When subsequent shaping operations are carried out, the height matching relationship between the shaping rod 22 and the tab 31 is more accurate, thus ensuring the shaping effect.

[0034] Specifically, the first linear driving device 1 is arranged in the middle of the lower side surface of the pressing plate 5, and plate group pressing frames 6 are arranged on both sides of the first linear driving device 1 to ensure the flattening effect on the plate group. At the same time, driving avoidance openings 61 and shaping rod guiding holes 62 are provided on the plate group pressing frame 6. The output end of the first linear driving device 1 passes through the driving avoidance opening 61 and is connected to the connecting plate 23. Multiple shaping rods 22 are respectively inserted into each shaping rod guiding hole 62. The setting of the shaping rod guiding holes 62 further ensures the positional relationship between the plate group pressing frame 6 and the shaping rod 22, that is, it ensures the accuracy of the height matching relationship between the shaping rod 22 and the tab 31 after the plate group pressing frame 6 reaches the proper position. Moreover, the shaping rod 22 is always within the shaping rod guiding hole 62, that is, the plate group pressing frame 6 undertakes part of the supporting role for the shaping frame 2, thereby reducing the supporting pressure on the first linear driving device 1.

[0035] To ensure the accuracy of the cooperation between this device and the storage battery, this device further includes a blocking and positioning mechanism. The blocking and positioning mechanism includes a third linear driving device 7 and a baffle 8 provided at the output end of the third linear driving device 7. The third linear driving device 7 can also adopt devices such as air cylinders and electric cylinders, and is arranged above with the output end facing downwards to drive the baffle 8 to move downwards to block the storage battery 3 being transported. After the ear shaping work is completed, the baffle 8 rises to release the storage battery. Of course, in order to obtain the signal that the storage battery is in place to accurately control this device and the storage battery conveying mechanism, a storage battery in-place sensor 9 is provided on one side of the blocking and positioning mechanism close to the second linear driving device. An opening 51 is provided on the pressing plate 5 corresponding to the storage battery in-place sensor 9. The storage battery in-place sensor 9 generally can adopt a photoelectric switch, which is also arranged above and passes through the opening 51 to sense downwards. When the storage battery is in place, an electrical signal can be obtained.

[0036] To improve the overall working efficiency, as needed, two groups, three groups or more groups of pole group pressing frames 6 and ear shaping mechanisms can be provided on each pressing plate 5. Moreover, two groups or more groups of pole group flattening mechanisms can also be provided and arranged by using the frame 10. The frame 10 has a simple structure and includes a support column 101 and a cross beam 102. The pole group flattening mechanism is arranged below the cross beam 102.

[0037] The above is only a preferred specific embodiment of the present utility model. This specific embodiment is a realization method based on the overall concept of the present utility model, and the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
