Description

Technical Field

[0001] The utility model belongs to the technical field of disassembling equipment, and in particular relates to a device for separating an electric core from a lower box. Background Art

[0002] The new energy industry is booming, and battery systems have attracted much attention. As the smallest battery unit, battery cells need to be modularized when used. Existing technology uses electrical connectors to connect single battery cells in series / parallel. The function of electrical connectors is to connect single battery cells in series / parallel to ensure that the battery pack forms an electrical connection path, so that the battery pack can provide electrical energy. At present, the combination of battery cells and electrical connectors is welding. The welding of battery cell tabs and electrical connectors requires high quality of electrical connectors and expensive welding equipment, which has high investment costs. Quality inspection is also required after welding, and there are undesirable factors such as leaking welds, cold welds, and false welds. Disassembling battery cells requires cutting, and the cutting method is a direct destruction, which makes the battery cells unusable and has a large loss. Therefore, as disclosed in patent CN116722318A, the electrical connector, battery cell, battery module, and assembly and disassembly tools for the battery cell and the electrical connector disclose a method for plugging and fixing the battery cell and the electrical connector, so that the battery cell does not need to be damaged when the battery cell is disassembled. Although the assembly and disassembly tools are also disclosed, manual disassembly is required, and the interference fit between the pole and the electrical connector requires a large force to separate the battery cell, which consumes energy and has a relatively low disassembly efficiency.

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] Example 1: Figures 1-4 As shown, a device for separating a battery cell from a lower box includes:

[0029] A fixed abutment frame 200 is used to abut against the lower box body 101 of the battery box;

[0030] The battery cell clamping member 201 is arranged on the abutment frame 200 and can move in a linear direction relative to the abutment frame 200. The battery cell clamping member 201 includes two clamping plates 202 fixed to each other. A gap is provided between the two clamping plates 202 to form a clamping cavity, and each clamping plate 202 is provided with a connector for connecting to the battery cell 100.

[0031] In this embodiment, the fixed abutment frame 200 abuts against the lower box body 101 of the battery box, and the clamping plate 202 on the battery cell clamping member 201 is connected to the battery cell. Then, when the battery cell clamping member 201 moves relative to the abutment frame 200, the lower box body 101 remains stationary under the abutment action of the abutment frame 200, and the battery cell clamping member 201 drives the battery cell to move relative to the lower box body 101, thereby realizing the separation between the battery cell and the lower box body 101, thereby replacing the existing manual disassembly method.

[0032] It should be noted that the electrical connector is fixedly connected to the lower box body 101 .

[0033] It is worth mentioning that when the battery cell 100 is assembled with the lower box body 101, the battery cell and the side beam 102 or the middle beam 103 of the lower box body 101 are separated by the pole 105, leaving space for the clamping plate 202 to extend into; and for the convenience of operation, the lower box body 101 to be disassembled is located below the abutment frame 200 and the clamping plate 202, and the clamping plate 202 moves in the vertical direction.

[0034] Preferably, the abutting frame 200 includes a first abutting portion 203 and a second abutting portion 204 for abutting against the beam on the lower box body 101 , and the first abutting portion 203 and the second abutting portion 204 are fixed.

[0035] In this embodiment, the beams on the lower box 101 form a mounting cavity for placing the battery cells, such as Figure 2As shown, the first abutting portion 203 can be set to abut against the side beam 102, and the second abutting portion 204 can abut against the middle beam 103. Then the setting of the first abutting frame 200 and the second abutting frame 200 can ensure that the force on the lower box body 101 is uniform.

[0036] Specifically, in order to increase the contact area between the first contact portion 203 and the second contact portion 204 and the corresponding beam, the contact surfaces of the first contact portion 203 and the second contact portion 204 are both planes.

[0037] Further preferably, the first abutting portion 203 and the second abutting portion 204 are both provided with screw connection holes 205 , and the set screw passes through the corresponding first abutting portion 203 and the second abutting portion 204 and is screwed and fixed to the beam on the lower box body 101 .

[0038] In this embodiment, the first abutting portion 203, the second abutting portion 204 and the beam on the lower box body 101 are abutted against each other, and a large force will be generated during the removal and insertion of the battery cell 100. Therefore, in order to ensure that the connection between the abutting frame 200 and the beam on the lower box body 101 will not be disconnected or offset during the insertion and removal process, screw connection holes 205 are provided on the first abutting portion 203 and the second abutting portion 204. The tightening screw passes through the screw connection hole 205 and is screwed and fixed to the beam on the lower box body 101, thereby strengthening the connection between the abutting frame 200 and the lower box body 101.

[0039] It is worth mentioning that, in order to facilitate installation, installation windows 206 are opened on the first abutting portion 203 and the second abutting portion 204, and the screw connecting hole 205 is located on the bottom wall of the installation window 206. The installation window 206 provides an operating space for the installation and removal of the fastening screw.

[0040] Preferably, a clamping drive member 212 is provided on the abutting frame 200 . The output shaft of the clamping drive member 212 can reciprocate in a linear direction, and the output shaft is fixed to the battery cell clamping member 201 .

[0041] Specifically, the first abutment portion 203 and the second abutment portion 204 are fixed by a mounting plate 207, the two clamping plates 202 are fixed by a connecting plate 208, the clamping drive member 212 is fixed on the mounting plate 207, and the output shaft on the clamping drive member 212 passes through the mounting plate 207 and is fixed to the connecting plate 208.

[0042] In this embodiment, the first abutment portion 203 and the second abutment portion 204 respectively include an abutment plate, and the two abutment plates are fixed by a mounting plate 207 to form a gantry, and the two clamping plates 202 are fixed by a connecting plate 208. The clamping drive member 212 is located on the mounting plate 207, and the output shaft of the clamping drive member 212 passes through the mounting plate 207 and is fixed to the connecting plate 208. The movement of the output shaft of the clamping drive member 212 in the vertical direction can drive the connecting plate 208 to move synchronously.

[0043] Specifically, along the moving direction of the connecting plate 208, a buffer pad 209 is provided on the mounting plate 207. The buffer pad 209 is located between the mounting plate 207 and the connecting plate 208. The presence of the buffer pad 209 can absorb the impact force of the connecting plate 208 colliding with the mounting plate 207 at the end of the stroke.

[0044] Further preferably, the number of the clamping drive members 212 is two, the two clamping drive members 212 are distributed along the length direction of the mounting plate 207, the output shafts of the two clamping drive members 212 pass through the mounting plate 207 and are fixed to the connecting plate 208; and each clamping drive member 212 is connected to a controller.

[0045] In this embodiment, the function of the clamping drive member 212 is to drive the two clamping plates 202 to move. Due to the existence of the connecting plate 208, the output shaft of one clamping drive member 212 can be connected to the two clamping plates 202. However, in order to enable the operating stroke of each clamping plate 202 to be separately regulated during the movement of the clamping plate 202, it is preferred to set two clamping drives 212 on the mounting plate 207, that is, in the process of the clamping plate 202 driving the battery cell 100 to move, if the working stroke of the battery cell 100 is offset, the position of the clamping plate 202 can be adjusted in time.

[0046] like Figure 4 As shown, two driving cylinders are provided on the mounting plate 207, and each driving cylinder is connected to a driver, which can be independently controlled. During the removal and removal of the battery cell 100, it is preferred to set the two driving cylinders to move together. Only when the battery cell 100 is offset, each driving cylinder will be independently controlled and adjusted; of course, the clamping drive member 212 can also use other linear output drive members such as hydraulic push rods.

[0047] Specifically, the connecting member includes an abutting screw 210 threadedly provided on each clamping plate 202 . When the battery cell 100 is located in the clamping cavity, the abutting screw 210 extends out to abut against the battery cell 100 .

[0048] In this embodiment, the side surfaces of each clamping plate 202 are screwed with abutment screws 210. After the clamping plate 202 moves down to both sides of the battery cell 100, the abutment screws 210 are locked so that they abut against the outer wall of the battery cell 100, thereby increasing the connection force between the clamping plate 202 and the battery cell 100 and ensuring that the clamping plate 202 and the battery cell 100 remain relatively stable during the pulling-up process of the clamping plate 202.

[0049] It is worth mentioning that Figure 2 As shown, if there is a difference in height between the middle beam 103 and the side beam 102 of the lower box body 101, the lengths of the first abutting portion 203 and the second abutting portion 204 need to be adjusted accordingly. When separating the battery cell 100, first adjust the abutting screw 210 on the left to a suitable position, then move the clamping plate 202 down to the set setting, and then adjust the abutting screw 210 on the right to abut against the battery cell 100, and cooperate with the abutting screw 210 on the left to clamp the battery cell 100. When the clamping plate 202 retracts, it can drive the battery cell 100 to move synchronously and separate it from the lower box body 101.

[0050] Example 2: Figure 5-Figure 8 As shown, the rest of the structure is the same as that of the first embodiment, with the only difference being that the connecting member includes a hook 211 provided on each clamping plate 202 , and when the battery cell 100 is located in the clamping cavity, the hook 211 is hooked and fixed with the ear 104 reserved on the battery cell 100 .

[0051] In this embodiment, a lifting ear 104 is reserved on the pole 105 of the battery cell 100 to facilitate the subsequent removal of the battery cell 100. A hook 211 is provided on the clamping plate 202, and the hook 211 is hooked and fixed with the lifting ear 104 to achieve connection with the battery cell 100.

[0052] It is worth mentioning that the hook 211 comprises a lock body, a lock handle and a shaft, and has a self-locking function to prevent the battery cell 100 from being accidentally unhooked during the lifting process.
