For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] See also Figure 1-3 As shown, the utility model is a battery cell module steel belt disassembly device, which is used to assist manual labor in disassembling a steel belt 110 disposed outside a battery cell module 100 .

[0038] The battery cell module 100 is formed by stacking a plurality of battery cells. End plates 120 for protecting the battery cells are disposed at both ends of the battery cell module 100. The end plates 120 are covered with an upper steel belt 111 and a lower steel belt 112 for bundling the plurality of battery cells together.

[0039] The battery cell module steel strip disassembly equipment includes a bearing assembly 1, a first extrusion assembly 2 and a second extrusion assembly 3. The bearing assembly 1 has a bearing surface for bearing the battery cell module 100. The first extrusion assembly 2 and the second extrusion assembly 3 are arranged opposite to each other and are used to extrude the battery cell module 100 on the bearing surface from both ends. The extrusion surfaces of the first extrusion assembly 2 and the second extrusion assembly 3 and the battery cell module 100 are both located between the two steel strips 110 (upper steel strip 111 and lower steel strip 112) that bundle the battery cell module 100, and the projection area of ​​the battery cell module 100 in the extruded state covers the bearing surface along the direction perpendicular to the bearing surface.

[0040] When the steel strips 110 need to be removed, the cell module 100 is placed on the bearing surface of the bearing assembly 1, and the extrusion surfaces of the first extrusion assembly 2 and the second extrusion assembly 3 are respectively in contact with the corresponding end plates 120, and the cell module 100 is extruded from both ends. After a gap appears between the cell module 100 and the two steel strips 110, the upper steel strip 111 is manually removed from the top of the cell module 100, and the lower steel strip 112 is manually removed from the bottom of the cell module 100 (such as Figure 2 (in the direction indicated by the arrow in the middle). After the two steel strips 110 are removed, the first extrusion assembly 2 and the second extrusion assembly 3 release the pressing of the battery cell module 100, and the staff repairs the battery cell module 100. After the repair is completed, the first extrusion assembly 2 and the second extrusion assembly 3 press the battery cell module 100 again, and then put the two steel strips 110 on the battery cell module 100 again, so as to avoid the need to cut the steel strips 110 when the battery cell is removed for repair or replacement, so that the steel strips 110 can be reused.

[0041] In one example, the battery cell module steel strip disassembly equipment further includes a base 4 , and the supporting assembly 1 , the first extrusion assembly 2 and the second extrusion assembly 3 are all mounted on the base 4 .

[0042] Specifically, four rollers 5 are provided at the bottom end of the base 4 to facilitate the overall movement of the battery cell module steel strip disassembly equipment.

[0043] The bearing assembly 1, the first extrusion assembly 2 and the second extrusion assembly 3 are all installed on the top of the base 4, and guide rails 6 are fixed on both sides of the top of the base 4. Along the length direction of the guide rails 6, the first extrusion assembly 2 and the second extrusion assembly 3 are respectively arranged on both sides of the bearing assembly 1.

[0044] The first extrusion assembly 2 includes a first sliding plate 21, a first driving device 22 and a first extrusion member 23. The first sliding plate 21 is slidably connected to the guide rail 6 through a first slider, the first driving device 22 is fixedly mounted on the first sliding plate 21, and the first extrusion member 23 is mounted on the driving end of the first driving device 22. When extruding the battery cell module 100, the staff can push the first sliding plate 21 to move along the length direction of the slide rail, and the first driving device 22 and the first extrusion member 23 are synchronously moved toward the battery cell module 100.

[0045] In this example, the battery cell module steel strip disassembly equipment also includes a first locking member, which is used to lock the first sliding plate 21 and the base 4, so that the first sliding plate 21 is fixed on the base 4, and the position of the first extrusion member 23 relative to the battery cell module 100 is preliminarily positioned. After that, the first driving device 22 drives the first extrusion member 23 further toward the battery cell module 100, and the position of the first extrusion member 23 relative to the battery cell module 100 is finely adjusted until the first extrusion member 23 abuts against the end plate 120 on one side of the battery cell module 100 and cooperates with the second extrusion assembly 3 to clamp the battery cell module 100.

[0046] In one example, the first locking member is a bolt, and a first threaded hole adapted for the first locking member is opened on the base 4, and multiple first threaded holes are spaced apart along the length direction of the guide rail 6, so that the first locking member can fix the first sliding plate 21 on the base 4 at different positions along the length direction of the guide rail 6, so as to facilitate the subsequent first extrusion member 23 to extrude battery cell modules 100 of different sizes.

[0047] Furthermore, in order to ensure the movement stability of the first extrusion member 23 driven by the first driving device 22, in this example, the battery module steel strip disassembly equipment also includes a second sliding plate 24, and the second sliding plate 24 is arranged adjacent to the first sliding plate 21, and the second sliding plate 24 is slidably connected to the guide rail 6 through a second slider, and the first extrusion member 23 is fixedly installed on the second sliding plate 24. When the first driving device 22 drives the first extrusion member 23 to move, the second sliding plate 24 slides along the length direction of the guide rail 6 to guide the movement of the first extrusion member 23.

[0048] In one example, the first driving device 22 includes a mounting seat 221, a screw 222, a worm wheel (not shown) and a rotating wheel 223. The mounting seat 221 is fixedly mounted on the first sliding plate 21. The mounting seat 221 is provided with a guide hole arranged along the length direction of the guide rail 6. The screw 222 is inserted into the guide hole, and one end of the screw 222 is rotatably connected to the first extrusion member 23 through a bearing. The rotating shaft of the rotating wheel 223 is rotatably connected to the mounting seat 221 through another bearing, and the worm wheel is fixedly mounted on one end of the rotating shaft of the rotating wheel 223 and meshes with the screw 222. When it is necessary to fine-tune the position of the first extrusion member 23, the staff can drive the screw 222 to slide along the length of the guide rail 6 (the length direction of the battery cell module 100) by rotating the rotating wheel 223, so that the screw 222 drives the first extrusion member 23 to move toward or away from the battery cell module 100.

[0049] The second extrusion assembly 3 includes a third sliding plate 31 and a second extrusion member 32, the second extrusion member 32 is fixedly mounted on the third sliding plate 31, and the third sliding plate 31 is slidably connected to the guide rail 6 through a third slider. The battery module steel strip disassembly device also includes a second locking member, which is used to lock the third sliding plate 31 with the base 4.

[0050] In one example, the second locking member is a bolt, and a second threaded hole adapted for the second locking member is opened on the base 4, and a plurality of second threaded holes are spaced apart along the length direction of the guide rail 6, so that the second locking member can fix the second sliding plate 24 on the base 4 at different positions along the length direction of the guide rail 6, so as to facilitate the subsequent second extrusion member 32 to extrude the battery cell modules 100 of different sizes.

[0051] When the cell module 100 needs to be disassembled, after the cell module 100 is placed on the carrier assembly 1, the second extrusion piece 32 on the right side is first pushed along the guide rail 6 to a position that fits the right end plate 120 of the cell module 100, and then the first extrusion piece 23 on the left side is pushed to a position that fits the left end plate 120 of the cell module 100. The first sliding plate 21 and the third sliding plate 31 are respectively fixed to the base 4 by the first locking member and the second locking member. The rotating wheel 223 is rotated to make the first extrusion piece 23 follow the screw 222 to continuously squeeze the cell module 100, so that a gap appears between the steel belt 110 and the cell, and the first steel belt 110 is manually removed upwards, and the second steel belt 110 is removed downwards.

[0052] See also Figure 4 and Figure 5 As shown, in one example, the bearing assembly 1 includes a pad for bearing the battery cell module 100, and the upper surface of the pad forms a bearing surface. The pad includes a fixed pad 11 and a movable pad 12. Along the length direction of the guide rail 6, the movable pad 12 is at least arranged at one end of the fixed pad 11. The fixed pad 11 is fixedly mounted on the base 4, and the movable pad 12 and the fixed pad 11 are detachably mounted. The movable pad 12 includes a plurality of movable pads 12 of different lengths. The staff can select one or more movable pads 12 of appropriate lengths and detachably mount them with the fixed pad 11 according to the specific size of the battery cell module 100 to support the battery cell module 100. Preferably, movable pads 12 are provided at both ends of the fixed pad 11, so that both ends of the fixed pad 11 can be connected to the movable pad 12 to increase the length of the bearing surface, so that the mechanical equipment for transporting the battery cell modules can transport battery cell modules of different sizes to the pads at a fixed coordinate.

[0053] In one example, the pad is strip-shaped, and multiple strips are provided along a direction perpendicular to the length of the guide rail 6 (in the width direction of the battery cell module 100). Compared with using a whole pad, using multiple strip-shaped pads is beneficial to reducing the overall weight of the pad.

[0054] Each cushion block includes a fixed cushion block 11 and a movable cushion block 12 which are detachably installed along the length direction of the guide rail 6 (the length direction of the battery cell module 100 ).

[0055] In one example, the bearing assembly 1 also includes a mounting beam 13, which is fixedly mounted on the top of the base 4, the fixed pad 11 is fixedly connected to the mounting beam 13, and the movable pad 12 is detachably connected to the mounting beam 13 via fasteners, so that the movable pad 12 is spliced ​​with the fixed pad 11.

[0056] In one example, bolts are used as fasteners, and the fixed pad 11 and the movable pad 12 are spliced ​​axially along the mounting beam 13. Since the positions of the screw holes that match the bolts on the movable pads 12 of different lengths are different, in order to ensure that the splicing between the movable pads 12 of different lengths and the fixed pad 11 is compact, the mounting beam 13 is provided with a T-slot along its axial direction, so that the fastener can cooperate with any position in the length direction of the T-slot to fix the movable pad 12 on the mounting beam 13.

[0057] In one example, the supporting assembly 1 also includes a guide portion 14 arranged on both sides of the fixed pad 11, and a guide slope inclined toward the fixed pad 11 is provided at the top of the guide portion 14. The guide slope is used to guide the falling direction of the battery cell module 100 when placing the battery cell module 100 on the pad, so that the battery cell module 100 can be completely placed on the pad.

[0058] In one example, the mounting beam 13, the pad and the guide part 14 are all mounted on the base 4 by bolts. In order to avoid opening many screw holes adapted to the bolts on the base 4, in this example, a mounting plate 7 is fixedly mounted on the top of the base 4, and the mounting plate 7 is provided with a number of screw holes corresponding to the bolts for fixing the mounting beam 13, the pad and the guide part 14, so that the mounting beam 13, the pad and the guide part 14 are all mounted on the mounting plate 7. Compared with opening many screw holes on the base 4, it is simpler to choose to open many screw holes on the mounting plate 7, which can save manufacturing costs.

[0059] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
