[0063] The existing drying fixtures for pouch batteries 301 have problems with poor compatibility and low changeover efficiency.

[0064] To address the above issues, a drying fixture for a soft-pack battery 301 is proposed.

[0065] A drying fixture for a pouch battery 301, such as Figure 1 , Figure 1 This is a schematic diagram of the first overall structure of the drying fixture for the soft-pack battery 301 in this utility model; it includes a fixed frame 100, multiple crossbars 200, multiple heating plates 300, a push plate 700, a drive mechanism 400, a height adjustment component 500, and a V-shaped plate 600; the multiple crossbars 200, drive mechanism 400, and height adjustment component 500 are installed inside the fixed frame 100, and the multiple heating plates 300 are slidably connected to the multiple crossbars 200 to form a heating interlayer; the multiple heating plates 300 are connected by... Multiple sets of connecting plates 302 are movably connected to each other; a push plate 700 is disposed on one side of multiple heating plates 300 and is fixedly connected to the drive mechanism 400; a V-shaped plate 600 is assembled between the heating plates 300 to protect the soft-pack battery 301; the drive mechanism 400 adjusts the thickness layer by layer by sequentially driving the push plate 700, the heating plate 300, and the V-shaped plate 600; a height adjustment component 500 is disposed below the V-shaped plate 600 and adjusts the height by raising / lowering the V-shaped plate 600.

[0066] In this embodiment, multiple heating plates 300 are movably connected to each other via multiple sets of connecting plates 302. The driving mechanism 400 sequentially drives the push plate 700, heating plate 300, and V-shaped plate 600 to adjust the thickness layer by layer. The height adjustment component 500 is set below the V-shaped plate 600, and the height is adjusted by raising / lowering the V-shaped plate 600. This allows for compatibility with soft-pack batteries 301 of different heights and thicknesses, achieving rapid changeover. This solves the problems of poor compatibility and low changeover efficiency of existing drying fixtures for soft-pack batteries 301.

[0067] It is worth noting that the V-shaped plate 600 can be made of various flexible or elastic materials, thereby providing force during the adjustment of thickness and height.

[0068] In this embodiment, the fixed frame 100 can be implemented as including four crossbeams 102 and two panels 101, with the four crossbeams 102 located at the four corners and the panels 101 located on both sides. The crossbars 200 can be implemented as four or other numbers, with both ends of the crossbars 200 mounted on the panels 101. The heating plate 300 has four circular holes 310 connected in series with the crossbars 200. Multiple sets of connecting plates 302 connect the upper, middle, and lower parts of the heating plate 300 in series and are movably connected to each other.

[0069] Each connecting plate 302 is provided with a movable hole. Adjacent heating plates 300 are movably connected through the movable hole. When the preceding heating plate 300 moves to both ends of the movable hole, it will generate a pulling force and a pushing force on the adjacent heating plate, thereby allowing for thickness adjustment.

[0070] In this embodiment, the push plate 700 is disposed on the inner side of the panel 101, and the drive mechanism 400 includes lead screws 410 on both sides and a drive plate 420. When adjusting the thickness, both sides of the push plate 700 are pushed simultaneously.

[0071] In this embodiment, multiple V-shaped plates 600 are placed horizontally on the height adjustment assembly 500, and the height is adjusted by raising / lowering or lowering the V-shaped plates 600.

[0072] In one possible implementation, the drive mechanism 400 includes a lead screw 410 and a drive plate 420; the drive plate 420 is threadedly connected to the lead screw 410 and fixedly connected to the push plate 700, and the drive plate 420 is driven to move by rotating the lead screw 410.

[0073] In this embodiment, there can be two combinations of lead screw 410 and drive plate 420, which are respectively arranged on both sides, and the two sets of mechanisms are connected by belt and transmission gear in the middle.

[0074] In one possible implementation, such as Figure 3 , Figure 3This is an exploded view of the overall structure of the drying fixture for the soft-pack battery 301 in this utility model; the V-shaped plate 600 includes a receiving groove 610; the side wall of the receiving groove 610 is attached to the heating plates 300 on both sides.

[0075] In one possible implementation, the depths of any two adjacent receiving slots 610 are not the same.

[0076] In one possible implementation, the bottom of the receiving groove 610 is a V-shaped structure 620.

[0077] In a preferred embodiment, the V-shaped plate 600 can be a single plate that fits into the heating plates 300 on both sides. However, the depths of the receiving grooves 610 of adjacent V-shaped plates 600 are different, and their upper parts are flush. This allows the soft-pack battery 301 to have different heights, making it easier for the robot to grasp and improving work efficiency.

[0078] In a preferred embodiment, the V-shaped plate 600 can be implemented as an integral W-shaped structure, but the depth of its receiving groove 610 is different. Specifically, the upper end of the receiving groove 610 is flush, and the depth of the lower end changes sequentially. Since the height of the soft-pack battery 301 is constant, the upper part of the soft-pack battery 301 changes sequentially, which is conducive to grasping and improving work efficiency.

[0079] In one possible implementation, such as Figure 2 , Figure 2 This is a schematic diagram of the second overall structure of the drying fixture for the soft-pack battery 301 in this utility model; the height adjustment component 500 includes multiple V-blocks 510, multiple support rods 520, and a height adjustment plate 530; each support rod 520 is movably connected to the fixed frame 100 through the height adjustment plate 530; the upper part of the V-block 510 is provided with a V-groove adapted to the V-shaped structure 620; the V-block 510 is used to support the V-shaped plate 600, and the heights of any two adjacent V-blocks 510 are not the same, so as to keep the openings of the receiving grooves 610 of all V-shaped plates 600 at the same level.

[0080] In this embodiment, the support rod 520 can be implemented as two. The height of the V-block 510 corresponds to the depth of the receiving groove 610 of the V-plate 600, and the depths are different in sequence. This allows the bottom of the V-block 510 to be placed flush with the support rod 520. When adjusting the height, multiple support rods 520 can be raised / lowered simultaneously.

[0081] In one possible implementation, a stroke hole is provided at the position of the support rod 520 corresponding to the fixed frame 100; a plurality of height adjustment holes are provided on one side of the stroke hole; the height is adjusted by connecting the height adjustment plate 530 to the height adjustment holes of different heights.

[0082] In one possible implementation, the height adjustment assembly 500 further includes an adjustment cylinder; the height adjustment plate 530 is connected to the height adjustment hole via the adjustment cylinder.

[0083] In this embodiment, the height adjustment plate 530 raises / lowers the support rod 520 together with the V-block 510 and V-plate 600 by adjusting the cylinder and the circular holes 310 at different heights, thereby adapting to different models of soft-pack batteries 301.

[0084] In one possible implementation, the drying fixture further includes an elastic guard plate assembly 800; at least one elastic guard plate assembly 800 is formed or fixed to the upper part of each heating plate 300; the elastic guard plate assembly 800 is used to fix and guide the upper part of the pouch battery 301 to prevent tilting.

[0085] In one possible implementation, the elastic guard plate assembly 800 includes a guard plate 810 and a protective sleeve 820; the guard plate 810 is formed or mounted on the upper part of the heating plate 300; the protective sleeve 820 wraps around the top of the guard plate 810 to form a spindle shape.

[0086] In this embodiment, the spindle-shaped protective sleeve 820 not only protects the upper part of the soft-pack battery 301, but also guides it to prevent tilting, thereby facilitating the robot's grasping and improving work efficiency.

[0087] The drying fixture for the soft-pack battery 301 of this utility model connects multiple heating plates 300 to each other via multiple sets of connecting plates 302. The drive mechanism 400 sequentially drives the push plate 700, heating plate 300, and V-shaped plate 600 to adjust the thickness layer by layer. The height adjustment component 500 is set below the V-shaped plate 600, and the height is adjusted by raising / lowering the V-shaped plate 600. This allows for compatibility with soft-pack batteries 301 of different heights and thicknesses, achieving rapid changeover. This solves the problems of poor compatibility and low changeover efficiency of existing drying fixtures for soft-pack batteries 301.

[0088] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
