Technical Field
[0001] The utility model is applied to the technical field of battery formation and grading, and particularly relates to a formation and grading layer board assembly. Background Art
[0002] In the production process of soft-pack batteries, various performance tests need to be carried out on the products to ensure that the products meet the use requirements. For example, the formation and grading of soft-pack batteries are usually completed in an automated equipment, namely a formation and grading integrated machine. This equipment can accurately control the charging and discharging current, voltage and time, and at the same time collect and analyze the performance data of the batteries to process the batteries efficiently and accurately. The formation and grading integrated machine slides multiple groups of layer boards on guide rods to perform different tests under different working conditions. At present, for the existing layer board products on the market, due to the friction between the guide sleeve and the guide rod when the layer boards are pressed and moved, the pressure between the layer boards is inconsistent. After multiple sets of layer board assemblies are combined, the accumulated pressure difference leads to a large pressure difference between the batteries and a low pressure consistency of the batteries. When compatible with soft-pack battery products with large thickness differences, it is often necessary to replace the pressing blocks to ensure the contact between the ear tabs and the conductive PCB. The changeover of models is cumbersome and time-consuming, and the efficiency is low. If a formation and grading layer board assembly with a simple structure, accurate positioning, adaptable to soft-pack batteries of different sizes, capable of detecting multiple groups of batteries simultaneously, with a small pressure difference between multiple batteries and a short changeover time can be designed, the above problems can be solved.

[0019] As Figures 1 to 4 shown, in this embodiment, the present utility model includes a laminate module 1 and an adjusting module 2. The laminate module 1 includes a laminate 3. Sliding grooves 4 are provided at both edges of the laminate 3. The adjusting module 2 includes an up-and-down adjusting module 5, a left-and-right adjusting module 6, a block 7, and a PCB board 8. The up-and-down adjusting module 5 and the left-and-right adjusting module 6 are respectively slidably engaged with the upper end and the lower end of the sliding groove 4. The PCB board 8 is floatingly connected to the up-and-down adjusting module 5. The up-and-down adjusting module 5 drives the PCB board 8 to cooperate with the battery 9 on the laminate 3. The block 7 is connected to the movable end of the left-and-right adjusting module 6. Wedge-shaped grooves 11 are provided on both sides of the laminate 3. The left-and-right adjusting module 6 drives the block 10 to be wedge-shapedly engaged with the wedge-shaped groove 11 so that the block 10 cooperates with the PCB board 8. It can be seen that the battery 9 is fixed on both sides of the laminate 3. The up-and-down adjusting module 5 drives the PCB board 8 to adjust the height. The left-and-right adjusting module 6 drives the block 7 to cooperate with the wedge-shaped groove 11, so that the block 7 laterally pushes to drive the PCB board 8 to adjust the width, thereby realizing rapid ring-shaped change of soft-pack batteries with different shapes and sizes, and the applicability is stronger.
[0020] As Figure 1 andFigure 4 As shown in the figure, in this embodiment, linear bearing seats 12 are provided at both hanger ends of the laminated board. Linear bearings 13 are provided in the linear bearing seats 12. A plurality of groups of the laminated boards 3 are matched with an external guide shaft 14 through the linear bearings 13 on both sides. It can be seen that the linear bearings 13 on the linear bearing seats 12 can ensure stable cooperation with the external guide shaft 14, realize the overall guiding movement of the laminated board 3, effectively reduce friction, and reduce the pressure difference between a plurality of the laminated boards 3.
[0021] As Figures 1 to 4 shown in the figure, in this embodiment, the up-and-down adjustment module 5 includes a first slider 51. The first slider 51 is slidably matched with the chute 4. A plurality of first roller shafts 52 are provided on the outer side of the first slider 51. The plurality of first roller shafts 52 are matched with an external first lifting rod. The PCB board 8 is floatingly connected to the first slider 51 through a floating module 53. It can be seen that the first slider 51 is matched with the external first lifting rod through the plurality of first roller shafts 52. While the plurality of first roller shafts 52 are clamped to prevent falling off, they can enable the laminated board 3 to perform an overall guiding movement. The external first lifting rod drives the first slider 51 to lift and lower so that the connection end of the PCB board 8 is matched with the battery 9.
[0022] As Figures 1 to 4 shown in the figure, in this embodiment, the left-and-right adjustment module 6 includes a second slider 61 and a connecting plate 62. The second slider 61 is slidably matched with the chute 4. The lower end of the connecting plate 62 is connected to the second slider 61. The bottom of the building block 7 is movably connected to the upper end of the connecting plate 62. A plurality of second roller shafts 63 are provided on the outer side of the second slider 61. The plurality of second roller shafts 63 are matched with an external second lifting rod. The second slider 61 drives the building block 7 to be matched with the wedge-shaped groove 11 through the connecting plate 62. It can be seen that the second slider 61 is matched with the external second lifting rod through the plurality of second roller shafts 63. While the plurality of second roller shafts 63 are clamped to prevent falling off, they can enable the laminated board 3 to perform an overall guiding movement. The external second lifting rod drives the second slider 62 to rise, and the building block 7 is wedge-shapedly matched with the wedge-shaped groove 11. The building block 7 is pushed laterally, thereby driving the PCB board 8 to move in the thickness direction. The first slider 51 and the second slider 61 independently control the movement of the PCB board 8 in the height and thickness directions, and can perform adaptive and rapid model change for soft-pack batteries of different sizes.
[0023] As Figure 1 and Figure 2As shown, in this embodiment, the layer plate 3 is provided with a U-shaped silicone pad 15, and the U-shaped silicone pad 15 is connected to the upper end of the layer plate 3 through a pressure strip 16 and a plurality of guide members 21. It can be seen that the U-shaped silicone pad 15 is in contact with the surface of the layer plate 3 to prevent the battery 9 from directly contacting the layer plate 3 and scratching the product 9, and the pressure strip 16 and a plurality of guide members 21 can fix the U-shaped silicone pad 15 on the layer plate 3 without deviation.
[0024] like Figure 2 As shown, in this embodiment, two groups of the bevel-shaped grooves 11 are respectively arranged at diagonal positions on both sides of the layer plate 3, and two groups of the batteries 9 are respectively arranged on one side of the bevel-shaped grooves 11. The adjustment modules 2 on both sides of the layer plate 3 respectively drive the height and width of the PCB board 8 and cooperate with the connection ends of the batteries 9 on both sides of the layer plate 3. It can be seen that the diagonal arrangement of the bevel-shaped grooves 11 enables the adjustment modules 2 on both sides of the layer plate 3 to test the two groups of batteries 9 at the same time, and balance the overall weight of the layer plate 3, so that the guided movement of the layer plate 3 on the external guide shaft 14 is more stable.
[0025] like Figure 1 and Figure 2 As shown, in this embodiment, a plurality of heating rods 17 are arranged inside the layer plate 3, and the plurality of heating rods 17 cooperate with the batteries 9 on both sides of the layer plate 3. A plurality of temperature sensors 18 are also arranged inside the layer plate 3, and the plurality of temperature sensors 18 cooperate with the plurality of heating rods 17. It can be seen that the plurality of heating rods 17 are built inside the layer plate, and cooperate with the plurality of temperature sensors 18 to control the temperature of the layer plate 3, thereby realizing the temperature control function.
[0026] like Figure 1 and Figure 2 As shown, in this embodiment, a spring pressure block 19 is arranged on the other side of the corresponding position of the two groups of the yoke-shaped grooves 11 on the layer plate 3, and the spring pressure block 19 cooperates with the PCB board 8 on the adjacent layer plate 3. It can be seen that when the left and right adjustment module 6 changes the shape of the PCB board 8 in the thickness direction, the building block 7 will drive the PCB board 8 to push sideways, and the PCB board 8 will push out the adjacent layer plate 3. The spring pressure block 19 is arranged at a position corresponding to the adjacent yoke-shaped groove 11. When the PCB board 8 pushes the adjacent layer plate 3 out a certain distance, the spring pressure block 19 provides a buffering effect to prevent the PCB board 8 from being damaged due to uneven force.
[0027] like Figures 1 to 4As shown in the figure, in this embodiment, the installation directions of the linear bearing seats 12 on two adjacent sets of the laminates 3 are opposite to each other up and down. Two adjacent sets of the laminates 3 are respectively matched with two sets of the external guide shafts 14 through the linear bearings 13. Thus, it can be seen that since the thickness of the linear bearing 14 is relatively large, by installing the adjacent linear bearing seats 12 in opposite directions up and down, the adjacent linear bearings 14 can be staggered from each other. Guided by the two sets of the external guide shafts 14, more sets of the laminates 3 can be accommodated, and the testing efficiency is higher.
[0028] As shown in FIG. 1 and Figure 2 As shown in the figure, in this embodiment, a hook screw 20 is further provided at the lower end of the laminate 3.
[0029] The working principle of the present utility model: Before the equipment is started, the laminates 3 carrying a number of batteries of different sizes are placed on the two sets of the guide shafts 14 for combined array. When the equipment is started, the adjustment module synchronously adjusts according to the model sizes of the batteries 9 on the laminates 3. The external first lifting rod drives the first slider 51 to lift and lower, adjusting the height of the connection end of the PCB board 8 and the battery 9 to be consistent. The external second lifting rod drives the second slider 61 to lift and lower, and the position of the PCB board 8 in the thickness direction is adjusted by pushing the side of the building block 7, so that a number of the PCB boards 8 can be accurately docked with the connection ends of a number of the batteries 9, and a number of sets of the laminates 3 are separated by a certain distance. A number of the batteries 9 are powered on, and a number of the heating rods 17 heat the laminates 3, realizing rapid model change and forming and grading the soft-pack batteries.
[0030] Although the embodiments of the present utility model are described with actual solutions, they do not constitute a limitation to the meaning of the present utility model. For those skilled in the art, the modifications to its implementation solutions according to this specification and the combinations with other solutions are obvious.
