Description

Technical Field

[0001] The utility model relates to the field of auxiliary equipment for manufacturing electric cores, in particular to a tab shaping mechanism. Background Art

[0002] After the battery cell has undergone IV and OCV testing, the next process is the shearing of the tabs. However, before shearing, the tabs must be flattened. Traditional tab shaping mechanisms mostly rely on Z-axis drive devices to flatten the two tabs of the battery cell by pressing down on the pressing block. Although this method is effective, it has significant limitations and is only applicable to the shaping of battery cells made of conventional materials. In particular, when the two tabs of the battery cell are made of different materials, the traditional mechanism is unable to cope with it. In addition, the tab shaping requirements of the battery cell are not generalized. It may only be necessary to shape the positive tab or the negative tab. The traditional structure cannot flexibly adapt to these changing requirements.

[0003] More importantly, traditional shaping equipment can only process a single battery cell at a time, which undoubtedly reduces the overall processing efficiency. In order to meet the diverse processing needs and improve production efficiency, the existing tab shaping mechanism needs to be improved so that it can flexibly respond to the tab shaping needs of different battery cells and realize the parallel processing of multiple battery cells at the same time. Therefore, it is necessary to produce a tab shaping mechanism to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a tab shaping mechanism to solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A pole ear shaping mechanism comprises a mounting bracket, a lifting support platform, a Y-axis drive assembly, a mounting vertical plate, a Z-axis drive assembly, an X-axis drive assembly, a spring buffer assembly and a shaping roller. The lifting support platform is fixed on the mounting bracket, the Y-axis drive assembly is fixed on the mounting bracket with a power output end facing the front side, the mounting vertical plate is fixed to the power output end of the Y-axis drive assembly and is slidably connected to the mounting bracket, the Z-axis drive assembly is fixed on the mounting vertical plate with a power output end facing the lower side, the X-axis drive assembly is fixed to the power output end of the Z-axis drive assembly, the upper end of the spring buffer assembly is fixed to the power output end of the X-axis drive assembly, the shaping roller is rotatably mounted on the lower end of the spring buffer assembly, the Z-axis drive assembly and the X-axis drive assembly are each provided with two groups, each group of X-axis drive assemblies is provided with two groups of spring buffer assemblies and shaping rollers, the spring buffer assemblies on one group of X-axis drive assemblies are spaced from the spring buffer assemblies on another group of X-axis drive assemblies, and the four groups of shaping rollers all correspond to the upper side of the lifting support platform.

[0007] Further description of the utility model: The shaping roller is made of zirconium oxide ceramics.

[0008] Further description of the utility model: The lifting support platform includes a lifting motor, a Z-axis slide, a Z-axis skateboard and a rolling platform. The lifting motor and the Z-axis slide are fixed on the mounting bracket, the Z-axis skateboard is fixed to the power output end of the lifting motor and is slidably connected to the Z-axis slide, and the rolling platform is fixed to the upper end of the Z-axis skateboard and corresponds to the bottom of the shaping roller.

[0009] Further description of the utility model: The spring buffer assembly includes a first slider, a second slider, a fixed block and a compression spring. The first slider is fixed at the power output end of the X-axis drive assembly. The second slider is slidably connected to the first slider. The second slider can slide in a vertical direction on the first slider. The fixed block is fixed at the upper end of the first slider. The upper end of the compression spring is fixed on the fixed block. The lower end of the compression spring is fixed on the top of the second slider. The shaping roller is rotatably mounted on the bottom of the second slider.

[0010] The beneficial effects of the utility model are as follows: when the battery cell is transported to the tab shaping mechanism in the current process, the lifting support platform rises and supports the bottom of the tab of the battery, the Z-axis driving assembly drives the spring buffer assembly and the shaping roller to descend, and the shaping roller is pressed against the upper end surface of the tab, and the Y-axis driving assembly drives the mounting vertical plate to reciprocate back and forth, so that the shaping roller reciprocates and rolls the tab, thereby shaping the tab. The design arranges two groups of Z-axis driving assemblies and X-axis driving assemblies respectively, and two groups of spring buffer assemblies and shaping rollers are arranged on each group of X-axis driving assemblies. The spring buffer assembly on one group of X-axis driving assemblies is spaced from the spring buffer assembly on the other group of X-axis driving assemblies, so that the tabs of two groups of batteries can be shaped at the same time, and the spacing between the shaping rollers can be adjusted by the X-axis driving assembly, so that a single tab of the battery can be shaped, and two tabs of the battery can also be shaped, so the shaping efficiency is higher and the flexibility of use is stronger.

[0016] The utility model is further described below in conjunction with the accompanying drawings:

[0017] like Figures 1 to 3 As shown, a tab shaping mechanism comprises a mounting bracket 1, a lifting support platform 2, a Y-axis driving assembly 3, a mounting vertical plate 4, a Z-axis driving assembly 5, an X-axis driving assembly 6, a spring buffer assembly 7 and a shaping roller 8, wherein the lifting support platform 2 is fixed on the mounting bracket 1, the Y-axis driving assembly 3 is fixed on the mounting bracket 1 with the power output end facing the front side, the mounting vertical plate 4 is fixed on the power output end of the Y-axis driving assembly 3 and is slidably connected to the mounting bracket 1, the Z-axis driving assembly 5 is fixed on the mounting vertical plate 4 with the power output end facing the lower side, and the X-axis driving assembly Component 6 is fixed to the power output end of the Z-axis drive component 5, the upper end of the spring buffer component 7 is fixed to the power output end of the X-axis drive component 6, and the shaping roller 8 is rotatably installed on the lower end of the spring buffer component 7. The Z-axis drive component 5 and the X-axis drive component 6 are each provided with two groups, and each group of X-axis drive components 6 is provided with two groups of spring buffer components 7 and shaping rollers 8. The spring buffer components 7 on one group of X-axis drive components 6 are spaced apart from the spring buffer components 7 on another group of X-axis drive components 6, and the four groups of shaping rollers 8 all correspond to the top of the lifting support platform 2.

[0018] When the current process transports the battery cell to the tab shaping mechanism, the lifting support platform 2 rises and supports the bottom of the battery tab, the Z-axis drive assembly 5 drives the spring buffer assembly 7 and the shaping roller 8 to descend, and the shaping roller 8 is pressed against the upper end surface of the tab, and the Y-axis drive assembly 3 drives the mounting vertical plate 4 to reciprocate back and forth, so that the shaping roller 8 reciprocates and rolls the tab, thereby shaping the tab. In this design, two groups of Z-axis drive assemblies 5 and X-axis drive assemblies 6 are respectively arranged, and two groups of spring buffer assemblies 7 and shaping rollers 8 are respectively arranged on each group of X-axis drive assemblies 6. The spring buffer assembly 7 on one group of X-axis drive assemblies 6 is spaced from the spring buffer assembly 7 on the other group of X-axis drive assemblies 6, so that the tabs of two groups of batteries can be shaped at the same time, and the spacing between the shaping rollers 8 can be adjusted by the X-axis drive assembly 6, so that a single tab of the battery can be shaped, and two tabs of the battery can also be shaped, so that the shaping efficiency is higher and the flexibility of use is stronger.

[0019] The shaping roller 8 is made of zirconia ceramics, which has the advantages of high strength, high insulation, corrosion resistance and light weight.

[0020] The lifting support platform 2 includes a lifting motor 21, a Z-axis slide 22, a Z-axis skateboard 23 and a rolling platform 24. The lifting motor 21 and the Z-axis slide 22 are fixed on the mounting bracket 1. The Z-axis skateboard 23 is fixed to the power output end of the lifting motor 21 and is slidably connected to the Z-axis slide 22. The rolling platform 24 is fixed to the upper end of the Z-axis skateboard 23 and corresponds to the bottom of the shaping roller 8.

[0021] The lifting motor 21 drives the Z-axis slide plate 23 to run vertically on the Z-axis slide table 22, so that the rolling platform 24 runs up and down. When the pole ear is shaped, the rolling platform 24 rises and supports the lower end surface of the pole ear.

[0022] The spring buffer assembly 7 includes a first slider 71, a second slider 72, a fixed block 73 and a compression spring 74. The first slider 71 is fixed to the power output end of the X-axis drive assembly 6, the second slider 72 is slidably connected to the first slider 71, and the second slider 72 can slide in a vertical direction on the first slider 71. The fixed block 73 is fixed to the upper end of the first slider 71, the upper end of the compression spring 74 is fixed to the fixed block 73, and the lower end of the compression spring 74 is fixed to the top of the second slider 72. The shaping roller 8 is rotatably mounted on the bottom of the second slider 72.

[0023] After the shaping roller 8 just contacts the pole lug, the compression spring 74 is compressed, which plays a buffering role for the shaping roller 8. When the shaping roller 8 rolls on the pole lug, the compression spring 74 is in a compressed state, so that the shaping roller 8 applies a certain pressure to the pole lug, thereby shaping the pole lug.

[0024] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
