Technical Field

[0001] This utility model relates to a battery fixture. Background Technology

[0002] With the development of electronic technology and the popularization of electronic devices, the demand for batteries in electronic products such as tablets, computers and mobile phones has also exploded.

[0003] Cell welding is a crucial process in battery assembly, requiring the welding of metal components such as guide plates and connecting pieces to the positive and negative terminals of the battery. However, existing battery spot welding processes suffer from technical problems such as cumbersome spot welding positioning and complex operations.

[0004] In particular, when spot welding the guide plate assembly containing electronic components such as diodes to the battery pack, the guide plate assembly, which consists of multiple bendable components, is prone to shifting to both sides and causing the electronic components such as diodes to pop out of the battery, resulting in battery misalignment and making it impossible to perform the spot welding operation smoothly.

[0005] To address this technical problem, existing technologies, such as the method of manually adjusting the battery positioning by operators using bamboo sticks after placing the battery body and guide plate assembly into the battery fixture, have low production efficiency and are difficult to reduce the defect rate.

[0006] In view of the above-mentioned technical problems in the prior art, there is an urgent need for a battery fixture that can improve the positioning accuracy during spot welding and improve production efficiency. Utility Model Content

[0027] The embodiments of this utility model will now be described using the accompanying drawings. However, various limitations, technically preferred for carrying out this utility model, are added to the embodiments described below. Therefore, the scope of the technology disclosed herein is not limited to the following embodiments and the illustrated examples. Furthermore, the sizes, shapes, and proportions in the illustrated examples are merely illustrative and do not represent specific sizes, shapes, and proportions. In addition, in the drawings, common structures in the embodiments are labeled with the same symbols, and repeated descriptions are omitted; and for the same structures, the illustration of reference numerals is sometimes omitted.

[0028] First, the battery fixture described in this embodiment is used in the spot welding operation between a battery and a guide plate to fix the battery and the guide plate in the spot welding operation, thereby achieving precise positioning of the spot weld. Specifically, the battery fixture described in the embodiment is used to spot weld the connecting piece (plate-like portion) of the guide plate assembly, including a diode, to the respective electrode terminals of two single batteries that are fixedly connected side by side. In this operation, since the guide plate assembly includes multiple components that can be bent into each other, positioning the guide plate assembly is difficult. The structure of the guide plate assembly 100 used in this operation will be described below.

[0029] Figure 1 This is a perspective view of the guide plate assembly 100 according to the present invention. Figure 2 The diagram shows a front view of the guide plate assembly 100 according to this utility model. Figures 1-2 As shown, the guide plate assembly includes a first sheet portion 110, a second sheet portion 120, a third sheet portion 130, a first connecting portion 140, and a second connecting portion 150.

[0030] The first sheet portion 110 is L-shaped and includes two connecting pieces, one of which is used to connect to the first single battery 210 (see...). Figure 8 One end of the first single cell 210 has another connecting piece that stands out from one end of the first single cell 210 for electrical connection with other electronic components.

[0031] The structure of the second sheet portion 120 is the same as that of the first sheet portion 110, and it is L-shaped, including two connecting pieces, one of which is used to connect to the second single battery 220 (see Figure 8 One end of the second single cell 220, wherein another connecting piece stands out from one end of the second single cell 220.

[0032] The third sheet-like portion 130 is in the shape of a long strip, with one side for connecting to the other end of the first single battery 210 opposite to the aforementioned end, and the other side for connecting to the other end of the second single battery 220 opposite to the aforementioned end.

[0033] The first connecting portion 140 consists of three parts. Specifically, the first connecting portion 140 includes a sheet-like connecting portion 141 integrally formed with the first sheet-like portion 110 and bent relative to the first sheet-like portion 110, and a sheet-like connecting portion 141 integrally formed with the third sheet-like portion 130 and bent relative to the third sheet-like portion 130. The sheet-like connecting portions 141 and 141 correspond to the portions of the first connecting portion 140 that connect to the sheet-like portions (first sheet-like portion 110 and third sheet-like portion 130).

[0034] Furthermore, the first connecting portion 140 also includes a first diode 142 that is soldered to the two side plate-shaped connecting portions 141, 141. This first diode 142 functions as a reverse connection protection element in a battery pack consisting of two single cells, the first single cell 210 and the second single cell 220, and may also provide current limiting, voltage limiting, and other protective functions. Additionally, depending on the actual needs of the battery pack, the first connecting portion 140 may further include other electronic components, or it may not have the first diode 142 or may have other electronic components in place of the first diode 142.

[0035] The first connecting portion 140 can be folded or unfolded according to the bending angle of the sheet-like connecting portions 141, 141, the first sheet-like portion 110, and the third sheet-like portion 130. Furthermore, due to the flexibility of the sheet-like connecting portions 141, 141, and the first diode 142, it may also bend under external force.

[0036] The structure of the second connecting portion 150 is the same as that of the first connecting portion 140, consisting of three parts. The second connecting portion 150 includes a sheet-like connecting portion 151 integrally formed with and bent relative to the first sheet-like portion 110, and a sheet-like connecting portion 151 integrally formed with and bent relative to the third sheet-like portion 130. These sheet-like connecting portions 151 and 151 correspond to the portions of the second connecting portion 150 that connect to the sheet-like portions (first sheet-like portion 110 and third sheet-like portion 130). Furthermore, the second connecting portion 150 also includes a second diode 152 soldered to the sheet-like connecting portions 151 and 151 on both sides.

[0037] (First Implementation) The structure of the battery fixture 300 according to the first embodiment of this utility model will be described below. Figure 3 This is a perspective view schematically illustrating the battery fixture 300 according to the first embodiment of the present invention. Figure 3 As shown, the battery fixture 300 includes a first side plate 310, a second side plate 320, a cover plate 330, and a base plate 340. The components constituting the battery fixture 300 are freely detachable from each other. Figure 3 The diagram shows the assembly of the components. The internal space of the battery fixture 300 after assembly forms a tank for housing the battery 200 (hereinafter, the combination of the first single battery 210 and the second single battery 220 is simply referred to as battery 200) connected to the guide plate assembly 100.

[0038] Furthermore, an opening 333 is provided on the cover plate 330 of the battery fixture 300. When the battery 200, to which the guide plate assembly 100 is connected, is housed in the groove of the battery fixture 300, the first sheet portion 110 and the second sheet portion 120 of the guide plate assembly 100 are exposed from the opening 333. A spot welding device (not shown) performs spot welding on the first sheet portion 110, the second sheet portion 120, and the electrode terminals of the battery 200 through the opening 333. Figure 3 As shown, on the cover plate 330, two openings 333 are arranged vertically along the width direction of the cover plate 330. In other words, the battery 200, consisting of two single batteries 210 and 220, is arranged vertically in the groove of the battery fixture 300. The figure shows an example in which five sets of single batteries 210 and 220 can be placed in the battery fixture 300, but the number is not limited to this.

[0039] exist Figure 3 On the back side of the cover plate 330 shown, there are limiting blocks 331 and 332 for positioning between the guide plate assembly 100 and the battery 200. The following describes the structural example of the limiting blocks 331 and 332. Figure 4 A perspective view of the cover plate 330 according to the first embodiment of the present invention is shown schematically. Figure 5 This is a partially enlarged perspective view of the cover plate 330 according to the first embodiment of the present invention. Figures 4-5 As shown, the limiting blocks 331 and 332 are respectively set on both sides of the line connecting a set of openings 333 and 333 (in the width direction of the cover plate 330).

[0040] Specifically, the limiting blocks 331 and 332 include a first limiting block 331 and a second limiting block 332. The first limiting block 331 is disposed on one side of the vertical line of a set of openings 333 and 333, for abutting against the portion of the first connecting portion 140 that is connected to the first sheet portion 110. The second limiting block 332 is disposed on the other side of the vertical line of a set of openings 333 and 333, and is symmetrical with respect to the axis of the line connecting the set of openings 333 and 333, for abutting against the portion of the second connecting portion 150 that is connected to the second sheet portion 120.

[0041] Therefore, after the cover plate 330 is placed on the battery fixture 300, the guide plate assembly 100 can be squeezed and positioned by the limiting blocks 331 and 332 abutting against the sheet-like connecting part 141 of the first connecting part 140 and the sheet-like connecting part 151 of the second connecting part 150, so as to achieve the effect of precise positioning and facilitate subsequent spot welding operations.

[0042] In addition, such as Figure 5 As shown, the front ends of the limiting blocks 331 and 332 are respectively chamfered 3311 and 3321. The chamfers 3311 and 3321 are formed by cutting the front ends of the limiting blocks 331 and 332 into a certain bevel. Therefore, during the process of installing the cover plate 330 onto the battery fixture 300, the limiting blocks 331 and 332 smoothly and unobstructedly abut against the sheet-like connecting portions 141 of the first connecting portion 140 and 151 of the second connecting portion 150, allowing for more convenient positioning by the limiting blocks 331 and 332. Alternatively, rounded corners can be provided instead of chamfers 3311 and 3321.

[0043] Figure 6 This is a cross-sectional view schematically illustrating the battery fixture 300 according to the first embodiment of the present invention. Specifically, Figure 6 This is a cross-sectional view along the length of the battery fixture 300, as shown below. Figure 6 As shown, the limiting blocks 331 and 332 of the cover plate 330 fully abut against the sheet-like connecting portions 141 and 151 of the guide plate assembly 100, thereby the guide plate assembly 100 is fully positioned relative to the battery 200, and the deviation of the first connecting portion 140 and the second connecting portion 150 in directions other than the axial direction of the battery 200 is restricted.

[0044] Furthermore, by simultaneously limiting the deviation of the first connecting portion 140 and the second connecting portion 150 by a set of limiting blocks 331 and 332 provided on the cover plate 330, it is possible to suppress the rebound of each component of the guide plate assembly 100 during the assembly of the battery fixture 300.

[0045] In addition, such as Figure 6As shown, the lengths of the limiting blocks 331 and 332 are set so that the limiting blocks 331 and 332 do not interfere with the first diode 142 and the second diode 152, thereby avoiding damage to the components.

[0046] In actual operation, firstly, the guide plate assembly 100 is assembled onto the battery 200. Then, the battery 200, with the guide plate assembly 100 connected, is placed in the battery fixture 300 before the cover plate 330 is installed. Next, the cover plate 330 is installed, causing the limiting blocks 331 and 332 to abut against the sheet-like connecting portion 141 of the first connecting portion 140 and the sheet-like connecting portion 151 of the second connecting portion 150. Afterward, spot welding is performed on the guide plate assembly 100 and the battery 200 within the groove of the installed battery fixture 300. These operations can be performed manually or utilized in an automated production line using automated equipment such as robotic arms.

[0047] (Second Implementation) The structure of the battery fixture 301 according to the second embodiment of this utility model is described below. Similar to the first embodiment, the battery fixture 301 is also composed of a first side plate 310, a second side plate 320, a cover plate 330 and a bottom plate 340. The differences are described below. Figure 7 A cross-sectional view of the battery fixture 301 according to the second embodiment of the present invention is shown schematically. Figure 8 The top view is shown schematically of the battery fixture 301 according to the second embodiment of the present invention.

[0048] First, compared to the first embodiment where the battery 200, consisting of two single batteries 210 and 220, is arranged vertically within the groove of the battery fixture 300, as... Figures 7-8 As shown, in the second embodiment, a battery 200 consisting of two single batteries 210 and 220 is arranged laterally in the groove of the battery fixture 301.

[0049] Furthermore, instead of the structure in the first embodiment where limiting blocks 331 and 332 are provided on the cover plate 330, such as... Figures 7-8 As shown, in the second embodiment, a first limiting block 311 and a second limiting block 321 are respectively provided in the first side plate 310 and the second side plate 320.

[0050] like Figure 7As shown, the first limiting block 311 in the first side plate 310 consists of a set of two first limiting blocks 311 respectively disposed at the upper and lower ends of the first side plate 310. Specifically, when the battery 200 connected to the guide plate assembly 100 is housed in the slot of the battery fixture 301, the upper first limiting block 311 abuts against the sheet-shaped connecting portion 141 of the first connecting portion 140 that is connected to the first sheet-shaped portion 110; the lower first limiting block 311 abuts against the sheet-shaped connecting portion 141 of the first connecting portion 140 that is connected to the third sheet-shaped portion 130.

[0051] And, as Figure 7 As shown, the second limiting block 321 in the second side plate 320 consists of a set of two second limiting blocks 321 respectively disposed at the upper and lower ends of the second side plate 320. Specifically, when the battery 200 connected to the guide plate assembly 100 is housed in the slot of the battery fixture 301, the upper second limiting block 321 abuts against the sheet-like connecting portion 151 of the second connecting portion 150 that is connected to the second sheet-like portion 120; the lower second limiting block 321 abuts against the sheet-like connecting portion 151 of the second connecting portion 150 that is connected to the third sheet-like portion 130.

[0052] In addition, such as Figure 8 As shown, when viewed from above, the battery fixture 301 has a first limiting block 311 and a second limiting block 321 positioned on either side of the center of the length direction of the battery 200, which is composed of two single batteries 210 and 220, respectively, and the battery 200 is squeezed from both sides of the center of the length direction. Furthermore, in the second embodiment, the inwardly protruding front ends of the first limiting block 311 and the second limiting block 321 may also be provided with chamfers or rounded corners.

[0053] Therefore, after the first side plate 310 and the second side plate 320 are placed on and installed in the battery fixture 301, a set of first limiting blocks 311 and a set of second limiting blocks 321 respectively abut against the sheet-like connecting portion 141 of the first connecting portion 140 and the sheet-like connecting portion 151 of the second connecting portion 150. Thus, the guide plate assembly 100 is adequately positioned relative to the battery 200, and the deviation of the first connecting portion 140 and the second connecting portion 150 in directions other than the axial direction of the battery 200 is limited. This achieves precise positioning and facilitates subsequent spot welding operations.

[0054] In actual operation, firstly, the guide plate assembly 100 is assembled onto the battery 200. Then, the battery 200, with the guide plate assembly 100 connected, is placed in a battery fixture 301 where one of the first side plate 310 and the second side plate 320 has not yet been installed. Next, one of the first side plate 310 and the second side plate 320 is installed, causing a set of first limiting blocks 311 and a set of second limiting blocks 321 to abut against the sheet-like connecting portion 141 of the first connecting portion 140 and the sheet-like connecting portion 151 of the second connecting portion 150, respectively. Then, spot welding is performed on the guide plate assembly 100 and the battery 200 within the groove of the installed battery fixture 301. These operations can be performed manually or utilized in an automated production line using automated equipment such as robotic arms.

[0055] The embodiments of this utility model have been described above with reference to the accompanying drawings. The embodiments described above are merely specific examples of this utility model, used to understand this utility model, and are not intended to limit the scope of this utility model. Those skilled in the art can make various modifications, combinations, and reasonable omissions of elements in the embodiments based on the technical concept of this utility model, and the resulting methods are also included within the scope of this utility model.
