[0079] The existing drying fixtures for pouch batteries 301 have problems with poor compatibility and low changeover efficiency.

[0080] To address the above problems, a drying fixture for a soft-pack battery 301 and an automatic changeover method are proposed.

[0081] Firstly, a drying fixture for a soft-pack 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 invention; it includes a fixed frame 100, multiple crossbars 200, multiple heating plates 300, a drive mechanism 400, a height adjustment component 500, and an elastic protective component 600; the multiple crossbars 200, drive mechanism 400, and height adjustment component 500 are installed inside the fixed frame 100; the multiple heating plates 300 are slidably connected to the multiple crossbars 200 to form a heating interlayer; the multiple heating plates 300 are movably connected to each other through multiple sets of connecting plates 302; the drive mechanism 400 adjusts the thickness of each layer by driving the heating plates 300 sequentially; the height adjustment component 500 is located below the soft-pack battery 301 and adjusts the height by changing the height of the soft-pack battery 301; the elastic protective component 600 is located on the upper part of each heating plate 300 and is used to guide and protect the upper part of the soft-pack battery 301.

[0082] 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 to 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.

[0083] Each connecting plate 302 is provided with a movable hole. Adjacent heating plates are movably connected through the movable hole. When the preceding heating plate 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.

[0084] In this embodiment, when a change of model is required, the upper part of the soft-pack battery 301 is guided by the elastic protective component 600; the thickness of each layer is adjusted by sequentially driving the heating plate 300; and the height of the soft-pack battery 301 is adjusted by changing the height of the soft-pack battery 301 by the height adjustment component 500 until the soft-pack battery 301 model is compatible.

[0085] In one possible implementation, such as Figure 3 , Figure 3 This is an exploded view of the overall structure of the drying fixture for the soft-pack battery 301 in this invention; the driving mechanism 400 includes a lead screw 410, a driving plate 420, a push plate 430, and a V-shaped protective plate 440; the driving plate 420 is threadedly connected to the lead screw 410 and fixedly connected to the push plate 430, and the driving plate 420 is driven to move by rotating the lead screw 410; the push plate 430 is disposed between the heating plate 300 and the panel 101 of the fixed frame 100, and is fixedly connected to the driving plate 420; the V-shaped protective plate 440 is assembled between the heating plates 300 to protect and support the soft-pack battery 301; the driving plate 420 adjusts the thickness layer by layer by sequentially driving the heating plate 300 and the V-shaped protective plate 440.

[0086] It is worth noting that the V-shaped protective plate 440 can be made of various flexible or elastic materials, thereby providing force during the thickness adjustment process.

[0087] In this embodiment, the drive mechanism 400 includes lead screws 410 on both sides and a drive plate 420. During thickness adjustment, both sides of the push plate 430 are pushed simultaneously. Multiple V-shaped protective plates 440 are placed horizontally on the height adjustment assembly 500, and the height is adjusted by raising or lowering the V-shaped protective plates 440.

[0088] 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.

[0089] In one possible implementation, the V-shaped protective plate 440 includes a receiving groove 441; the sidewall of the receiving groove 441 is attached to the heating plates 300 on both sides, the depth of any two adjacent receiving grooves 441 is different, and the bottom of the receiving groove 441 is a V-shaped structure 442.

[0090] In a preferred embodiment, the V-shaped protective plate 440 can be a single plate that fits into the heating plates 300 on both sides. However, the depths of the receiving grooves 441 of adjacent V-shaped protective plates 440 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.

[0091] In a preferred embodiment, the V-shaped protective plate 440 can be implemented as an integral W-shaped structure, but the depth of its receiving groove 441 is different. Specifically, the upper end of the receiving groove 441 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 gripping and improving work efficiency.

[0092] When adjusting the thickness, the rotating screw 410 drives the drive plate 420 to slide, and the drive plate 420 drives the push plate 430 to move; the push plate 430 pushes the adjacent heating plate 300 to move; the above steps are performed continuously to adjust the thickness of the heating plate 300 layer by layer.

[0093] 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 invention;

[0094] The height adjustment assembly 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 442; the V-block 510 is used to support the V-shaped protective plate 440, and the heights of any two adjacent V-blocks 510 are different, so as to keep the openings of the receiving grooves 441 of all V-shaped protective plates 440 at the same level.

[0095] 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; 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.

[0096] In this embodiment, the height adjustment plate 530 raises the support rod 520 together with the V-block 510 and the V-shaped protective plate 440 by adjusting the cylinder and the circular holes 310 at different heights, thereby adapting to different models of soft-pack batteries 301.

[0097] When adjusting the height, the height adjustment plates 530 of each height adjustment component 500 are installed on the corresponding round holes 310 of the panel 101 of the fixed frame 100 using the adjustment cylinder; the height of the V-block 510 and the V-shaped protective plate 440 located on the V-block 510 are adjusted using the support rod 520.

[0098] In one possible implementation, the drying fixture further includes an elastic protective component 600; at least one elastic protective component 600 is formed or fixed on the upper part of each heating plate 300; the elastic protective component 600 is used to fix and guide the upper part of the pouch battery 301 to prevent tilting.

[0099] In one possible implementation, the elastic protective component 600 includes a protective plate 610 and a protective sleeve 620; the protective plate 610 is formed or mounted on the upper part of the heating plate 300; the protective sleeve 620 wraps around the top of the protective plate 610 to form a spindle shape.

[0100] In this embodiment, the spindle-shaped protective sleeve 620 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.

[0101] 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 430, heating plate 300, and V-shaped protective plate 440 to adjust the thickness layer by layer. The height adjustment component 500 is set below the V-shaped protective plate 440, and the height is adjusted by raising / lowering the V-shaped protective plate 440. 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.

[0102] Secondly, an automatic changing method for the drying fixture of a pouch battery 301 is provided, employing the drying fixture for the pouch battery 301 described in the first aspect, such as... Figure 4 , Figure 4 This is a schematic diagram of a specific embodiment of the automatic fixture changing method for drying the soft-pack battery 301 in this invention; including:

[0103] Step 10: Install multiple crossbars 200, drive mechanism 400, and height adjustment component 500 inside the fixed frame 100. Slidably connect multiple heating plates 300 to the multiple crossbars 200 to form a heating interlayer. Connect the multiple heating plates 300 to each other through multiple sets of connecting plates 302. Set the elastic protection component 600 on the upper part of each heating plate 300 and set the height adjustment component 500 below the soft-pack battery 301. Step 20: Use the elastic protection component 600 to guide and protect the upper part of the soft-pack battery 301. Step 30: Adjust the thickness of each layer by driving the heating plates 300 sequentially and adjust the height of the soft-pack battery 301 by changing the height using the height adjustment component 500 until the soft-pack battery 301 model is compatible.

[0104] The drive mechanism 400 includes a lead screw 410, a drive plate 420, a push plate 430, and a V-shaped protective plate 440. The height adjustment assembly 500 includes multiple V-shaped blocks 510, multiple support rods 520, a height adjustment plate 530, and an adjustment cylinder.

[0105] In one possible implementation, such as Figure 5 , Figure 5 for Figure 4 A schematic diagram of a specific embodiment of step 30; step 30 includes:

[0106] Step 31: Rotate the lead screw 410 to drive the drive plate 420 to slide, and use the drive plate 420 to drive the push plate 430 to move; Step 32: Use the push plate 430 to push the adjacent heating plate 300 to move; Step 33: Continuously perform steps 31-32 to adjust the thickness of the heating plate 300 layer by layer.

[0107] In one possible implementation, such as Figure 6 , Figure 6 for Figure 4 Another specific embodiment of step 30 is illustrated; step 30 also includes:

[0108] Step 34: Using the adjusting cylinder, install the height adjusting plates 530 of each height adjusting component 500 onto the corresponding round holes 310 of the panel 101 of the fixed frame 100; Step 35: Use the support rod 520 to adjust the height of the V-block 510 and the V-shaped protective plate 440 located on the V-block 510.

[0109] The drying fixture and automatic changeover method for the soft-pack battery 301 of the present invention achieves rapid changeover by connecting multiple heating plates 300 to each other via multiple sets of connecting plates 302, using a drive mechanism 400 to sequentially drive the push plate 430, heating plates 300, and V-shaped protective plate 440 for layer-by-layer thickness adjustment, and using a height adjustment component 500 positioned below the V-shaped protective plate 440 to adjust the height by raising / lowering the V-shaped protective plate 440. This allows for compatibility with soft-pack batteries 301 of different heights and thicknesses, solving the problems of poor compatibility and low changeover efficiency in existing drying fixtures for soft-pack batteries 301.

[0110] The drying fixture and automatic changeover method for the soft-pack battery 301 of the present invention achieves rapid changeover by connecting multiple heating plates 300 to each other via multiple sets of connecting plates 302, using a drive mechanism 400 to sequentially drive the push plate 430, heating plates 300, and V-shaped protective plate 440 for layer-by-layer thickness adjustment, and using a height adjustment component 500 positioned below the V-shaped protective plate 440 to adjust the height by raising / lowering the V-shaped protective plate 440.
