Description

Technical Field

[0001] The utility model belongs to the technical field of battery pole plates, and more specifically relates to an environmentally friendly anti-reverse pole lead-carbon battery pole group structure. Background Art

[0002] Due to the internalization production process, the positive and negative plates have little difference in color and size. In the process of pole group assembly, it is easy to confuse the positive and negative plates, resulting in pole plate reverse polarity. Since the pole group is basically an axisymmetric structure, it is very easy to cause pole group reverse polarity during the pole group shelling process. Since the internalization production process uses uncharged raw plates for assembly, the existing battery cluster cannot accurately and effectively identify the reverse polarity problem. In addition to visual inspection, there is no other auxiliary detection equipment or better detection means. Therefore, the problem of pole plate reverse polarity is inevitable in production. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] See also Figure 1 and Figure 2 , the environment-friendly anti-reverse lead-carbon battery pole group structure provided by the utility model is now described. The environment-friendly anti-reverse lead-carbon battery pole group structure includes: a pole plate assembly, a plurality of first reinforcing blocks 5 and a plurality of second reinforcing blocks 6. The pole plate assembly includes a plurality of positive plates 11, a plurality of negative plates 2 and a plurality of partitions 1, and the partitions 1 are positioned between the positive plates 11 and the negative plates 2; and the positive pole ears 3 and the negative pole ears 4 are fixed on the positive plates 11 and the negative plates 2, respectively. A plurality of first reinforcing blocks 5 are respectively fixed between the positive plates 11 and the positive pole ears 3, and a first detection groove is provided on the first reinforcing block 5. A plurality of second reinforcing blocks 6 are respectively fixed between the negative plates 2 and the negative pole ears 4, and a second detection groove is provided on the second reinforcing block 6, and the projection area of ​​the second detection groove on the plane of the positive plate 11 is different from the projection area of ​​the first detection groove on the plane of the positive plate 11.

[0025] The beneficial effect of the environmentally friendly anti-reverse lead-carbon battery pole group structure provided by the utility model is that: compared with the prior art, the pole plate assembly in the environmentally friendly anti-reverse lead-carbon battery pole group structure of the utility model includes a plurality of positive plates 11, a plurality of negative plates 2 and a plurality of partitions 1, and the partition 1 is positioned between the positive plate 11 and the negative plate 2; and the positive pole ear 3 and the negative pole ear 4 are fixed on the positive plate 11 and the negative plate 2 respectively. The first reinforcing block 5 is respectively fixed between the positive plate 11 and the positive pole ear 3, and the second reinforcing block 6 is respectively fixed between the negative plate 2 and the negative pole ear 4. More importantly, the projection area of ​​the second detection slot on the plane of the positive plate 11 is different from the projection area of ​​the first detection slot on the plane of the positive plate 11.

[0026] In the present application, the first reinforcement block 5 and the second reinforcement block 6 are provided to ensure the reliability of the connection between the pole ear and the pole plate to a certain extent, avoiding the problem of cracks or even breakage between the pole ear and the pole plate. Since the projection areas of the two inspection grooves are different, the problem of battery reverse polarity is avoided through observation and inspection, thereby reducing the defective rate and scrap rate and reducing losses.

[0027] Lead-carbon batteries of different capacities are composed of different numbers of plates connected in parallel, and lead-carbon batteries of different voltages are composed of different numbers of single pole groups connected in series. During production, a certain number of positive and negative pole plates 2 are assembled and packaged according to the ratio, and then the positive pole plates 11 and the negative pole plates 2 are respectively connected in parallel to form pole groups by welding. The welded pole groups are loaded into the battery housing. Multi-monomer lead-carbon batteries require adjacent pole groups to be welded in series.

[0028] Whether it is the reverse polarity of the plates during assembly or the reverse polarity of the pole groups during shell installation, it has a fatal impact on the performance of lead-carbon batteries. Most reverse polarity batteries are discovered during capacity testing and need to be scrapped; a small number of reverse polarity batteries will manifest during customer use, which may damage the entire battery group used by the customer, causing greater harm.

[0029] In some embodiments of the environmentally friendly anti-reverse lead-carbon battery pole group structure provided in this application, please refer to Figure 1 and Figure 2 The plate assembly further includes a positive busbar 7 and a negative busbar 8, wherein the positive busbar 7 is connected to a plurality of positive tabs 3, and the negative busbar 8 is connected to a plurality of negative tabs 4. The existing lead-acid battery generally includes a pole group consisting of a plurality of positive plates 11 and a plurality of negative plates 2, wherein the positive tabs 3 and the negative tabs 4 in each pole group are respectively connected via a busbar, and only a single connection point can be set between the busbars of adjacent pole groups to realize the series connection of the pole groups.

[0030] A negative electrode ear 4 is provided on one side of the upper end of the negative electrode plate 2, and a positive electrode ear 3 is provided on one side of the upper end of the positive electrode plate 11. After a plurality of positive electrode plates 11, negative electrode plates 2 and separators 1 are overlapped and arranged, a plurality of positive electrode ears 3 overlap, and a plurality of negative electrode ears 4 overlap, forming an assembly structure with symmetrical electrode ears. Once the positive and negative electrode plates 2 are mixed and installed upside down, it is inconvenient to visually find the misalignment at both ends of the electrode group. By using the method in the present application, the electrode ears cannot be inserted into the welding mold for welding the positive bus 7 and the negative bus 8 after the misalignment, and the reverse polarity of the electrode plates can be intuitively judged, thereby avoiding the losses caused by scrapping or major dangerous accidents in the later stage after the completion of the production, and reducing the defective rate and scrap rate of the process.

[0031] In some embodiments of the environmentally friendly anti-reverse lead-carbon battery pole group structure provided in this application, please refer to Figure 1 and Figure 2, a mounting plate 9 is fixed on one side of the positive bus 7, and the mounting plate 9 is adapted to the plurality of first detection slots. Since the projection areas of the first detection slot and the second detection slot in the direction of the positive plate 11 are different, it is more important that the plurality of positive plates 11 and the plurality of negative plates 2 are arranged in a certain order, and after the plurality of positive plates 11 and the plurality of negative plates 2 are arranged, the projection areas of the plurality of positive plates 11 on one of the positive plates 11 or the negative plates 2 are the same. The projection areas of the plurality of negative plates 2 on one of the positive plates 11 or the negative plates 2 are the same. It is precisely because of the above arrangement that the first reinforcement block 5 and the second reinforcement block 6 are also arranged at intervals in a certain order.

[0032] If reverse polarity occurs during the assembly process, the first inspection slot and the second inspection slot will appear on the same side. At this time, visual inspection or detection with the help of relevant instruments can be used to determine whether reverse polarity has occurred.

[0033] In some embodiments of the environmentally friendly anti-reverse lead-carbon battery pole group structure provided in this application, please refer to Figure 1 and Figure 2 , the mounting plate 9 abuts against the multiple first reinforcing blocks 5. For a more detailed description, during the installation process, it is necessary to ensure that the end faces of the mounting plate 9 away from the positive bus 7 abut against the first reinforcing blocks 5, because only when the mounting plate 9 abuts against the multiple first reinforcing blocks 5 can it be ensured that no reverse polarity occurs, and further, it can be ensured that the installation position of the positive plate 11 meets the requirements, and it can be ensured that the positive electrode ear 3 on the positive plate 11 can effectively contact the positive bus 7.

[0034] In some embodiments of the environmentally friendly anti-reverse lead-carbon battery pole group structure provided in this application, please refer to Figure 1 and Figure 2 The mounting plate 9 is provided with a limit groove for engaging with the positive plate 11. After the plurality of positive plates 11 are installed, the spacing between adjacent plates and the distance between the plates and the housing are approximately equal. Since the mounting plate 9 is fixed according to the size specification of the first reinforcing block 5, if there is a reverse polarity, the mounting plate 9 will inevitably fail to be installed normally, so that the problem can be discovered and handled in time.

[0035] Furthermore, in order to ensure the stability of the spacing and relative positions between the electrode plates, a plurality of limit grooves may be provided on the mounting plate 9, and the plurality of limit grooves are respectively engaged with the corresponding plurality of positive electrode plates 11, and finally the stability of the positions between adjacent positive electrode plates 11 is ensured by the mounting plate 9.

[0036] In some embodiments of the environmentally friendly anti-reverse lead-carbon battery pole group structure provided in this application, please refer to Figure 1, the conductivity of the mounting plate 9 is lower than that of the positive electrode ear 3. The purpose of the above arrangement is to ensure that the current can only enter the positive bus 7 through the positive electrode plate 11, and to ensure the concentration of the current, because the mounting plate 9 is only abutted against the first reinforcing block 5. If there is current between the mounting plate 9 and the first reinforcing block 5, it will inevitably cause a change in resistance, resulting in instability of the current supplied by the entire battery.

[0037] Ideally, the mounting plate 9 is made of insulating material and does not exert a large compressive force on the positive electrode plate 11 .

[0038] In some embodiments of the environmentally friendly anti-reverse lead-carbon battery pole group structure provided in this application, please refer to Figure 1 , a detection board 10 is detachably mounted on the negative bus 8, and the end face of the detection board 10 away from the negative bus 8 abuts against the multiple second reinforcing blocks 6. For further explanation, firstly, a detection board 10 is detachably mounted on the negative bus 8. After the initial installation is completed and the position of the plate is verified, the detection board 10 is mounted on the negative bus 8. At this time, one end face of the negative bus 8 will abut against the multiple second reinforcing blocks 6. If the detection board 10 cannot be stably placed, resulting in the entire negative bus 8 being unable to be effectively fixed, then it can be determined that reverse polarity has occurred.

[0039] In some embodiments of the environmentally friendly anti-reverse lead-carbon battery pole group structure provided in this application, please refer to Figure 1 The negative bus 8 is provided with a slot for engaging with the detection board 10. In the actual application process, the negative bus 8 needs to be installed and fixed first. After the negative bus 8 is positioned, the detection board 10 is mounted on the negative bus 8. At this time, if the detection board 10 can be successfully engaged, it indicates that it can contact with all the second reinforcement blocks 6, thereby avoiding the occurrence of reverse polarity. After the detection is completed, the detection board 10 can be removed from the negative bus 8.

[0040] In some embodiments of the environmentally friendly anti-reverse lead-carbon battery pole group structure provided in this application, please refer to Figure 1 , the outer side surface of the first reinforcing block 5 is a straight surface, and the outer side surface of the second reinforcing block 6 is a curved surface. To explain in more detail, first, the positive ear 3 and the negative ear 4 are in the same situation, but the surface areas of the first reinforcing block 5 and the second reinforcing block 6 are different. It is precisely because of the different surface areas that after the detection board 10 and the mounting board 9 are installed, if reverse polarity occurs, it can be determined immediately. To explain in more detail, the outer side surface of the first reinforcing block 5 can be a straight surface, and the outer side surface of the second reinforcing block 6 can be a curved surface. Since the distances between the reinforcing blocks and the bus are different, the placement of the current plate can be accurately judged by visual inspection and other methods.

[0041] In some embodiments of the environmentally friendly anti-reverse lead-carbon battery pole group structure provided in this application, please refer to Figure 1 The first reinforcing block 5 and the second reinforcing block 6 are integrally formed on the positive plate 11 and the negative plate 2, respectively. The integral forming arrangement ensures the reliable connection between the plate and the tab, thus avoiding a series of problems such as cracks between the tab and the plate. In addition, the integral forming arrangement can reduce the number of processing steps and ensure accuracy.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
