[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0033] like Figure 1 As shown, the battery stack 8 includes a pressure plate 81, a battery cell 82 and a steel belt 83. An upper end plate is provided on the top of the battery cell 82, a lower end plate is provided on the bottom of the battery cell 82, the pressure plate 81 is located above the upper end plate, and a disc spring is provided between the upper end plate and the pressure plate 81. The steel belt 83 is wrapped around the pressure plate 81 and the lower end plate to compress the battery cell 82. Most parts of the steel belt 83 are tightly attached to the battery cell 82, the pressure plate 81 and the lower end plate, and these parts cannot be cut, otherwise the battery stack 8 will be damaged. However, there is a gap between the pressure plate 81 and the upper end plate, so the part of the steel belt 83 located between the upper end plate and the pressure plate 81 is not tightly attached to other parts, and on-site workers usually cut this part to avoid damaging the battery stack 8. This part is the cutting part 831.

[0034] like Figure 2 , Figure 3 and Figure 5 As shown, the utility model provides a battery stack disassembly and assembly auxiliary device, which includes a base plate 1, a support frame 2 and a clamping mechanism 3. The support frame 2 is installed on the top of the base plate 1, and the clamping mechanism 3 is installed on the support frame 2. A positioning area for placing the battery stack 8 is provided between the clamping mechanism 3 and the base plate 1. The clamping mechanism 3 is configured to be able to reciprocate toward or away from the positioning area to compress or relax the battery stack 8 placed in the positioning area. The clamping mechanism 3 is provided with a plurality of avoidance grooves 323 for avoiding the steel belt 83 of the battery stack 8.

[0035] Specifically, when it is necessary to disassemble the battery stack 8, the battery stack 8 is placed in the positioning area, and then the pressing mechanism 3 is moved downward to press the battery stack 8 between the pressing mechanism 3 and the substrate 1, and the steel belt 83 on the battery stack 8 is directly opposite the avoidance groove 323 of the pressing mechanism 3. The steel belt 83 on the battery stack 8 is cut off, and then the pressing mechanism 3 slowly releases the battery stack 8, so that the pressure of the battery stack 8 is slowly released until the battery stack 8 is completely released, and then the battery stack 8 is further disassembled. When it is necessary to re-press the battery stack 8, the battery stack 8 is placed in the positioning area, and then the pressing mechanism 3 is moved downward to press the battery stack 8 between the pressing mechanism 3 and the substrate 1, and then the steel belt 83 is tightened at the avoidance groove 323, and finally the pressing mechanism 3 slowly releases the battery stack 8 until it completely leaves the battery stack 8, and the battery stack 8 is re-pressed. Therefore, the battery stack disassembly and assembly auxiliary device can not only assist in disassembling the battery stack 8, but also assist in re-pressing the battery stack 8, so that the repaired battery stack 8 does not need to be returned to the original production line for pressurization, thereby improving maintenance efficiency.

[0036] In addition, after the pressing mechanism 3 presses the battery stack 8, the steel belt 83 faces the avoidance groove 323, so that an appropriate cutting operation space is reserved between the cutting part 831 and the pressing mechanism 3, which is convenient for cutting the steel belt 83.

[0037] like Figure 2 and Figure 3 As shown, in some embodiments of the utility model, the support frame 2 includes a top plate 22 and a plurality of support rods 21, the plurality of support rods 21 extend vertically and are installed on the top of the substrate 1 at intervals from each other, the top plate 22 is fixedly connected to the top ends of the support rods 21, and the clamping mechanism 3 is installed on the top plate 22.

[0038] Specifically, the number of the support rods 21 may be four, and the four support rods 21 are vertically connected to the base plate 1. The line connecting the bottom ends of the four support rods 21 is a rectangle. The positioning area is located between the support rods 21 and below the top plate 22.

[0039] like Figure 2 and Figure 3 As shown, in some embodiments of the utility model, the clamping mechanism 3 includes a jack 31 and a pressing component 32, the fixed end of the jack 31 is installed on the top plate 22, the pressing component 32 is located below the jack 31 and connected to the top pressing end of the jack 31, the jack 31 can drive the pressing component 32 to reciprocate toward or away from the positioning area, and the bottom of the pressing component 32 is provided with an avoidance groove 323 opening toward the positioning area.

[0040] Specifically, the jack 31 can provide a sufficiently large pressure to press the battery stack 8, and the top pressure end of the jack 31 moves slowly, which can prevent the pressure inside the battery stack 8 from being suddenly released and avoid hurting the workers on site. Of course, any jack 31 that can meet the use requirements of the utility model can be used, such as a hydraulic jack.

[0041] like Figure 4 and Figure 5 As shown, in some embodiments of the utility model, the pressing component 32 includes a connecting portion 321 and a pressing portion 322 connected to the bottom of the connecting portion 321, and the connecting portion 321 is connected to the top pressing end of the jack 31 and can be vertically slidably connected to the support rod 21. Therefore, in the process of the jack 31 driving the pressing component 32 to move, the movement of the pressing component 32 can be smoother, and the pressing component 32 can also be prevented from swinging horizontally. In addition, the avoidance groove 323 is provided in the pressing portion 322. Therefore, after the pressing portion 322 presses the battery stack 8, the steel belt 83 is opposite to the avoidance groove 323, so that an appropriate cutting operation space is reserved between the pressing component 32 and the cutting portion 831, which is convenient for cutting the steel belt 83.

[0042] In some embodiments, a vertically extending slide groove is provided on the side of the support rod 21, and a plurality of sliding parts connected to the connecting part 321 are also provided on the pressing part 32. These sliding parts are inserted into all the slide grooves one by one, so that the pressing part 32 can move vertically along the support rod 21.

[0043] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the connecting portion 321 is configured to be flat, and the connecting portion 321 is provided with a plurality of through holes, in which linear bearings 33 are installed, and all support rods 21 are correspondingly passed through all linear bearings 33 .

[0044] Specifically, the connection portion 321 can reciprocate vertically along the support rod 21 through the linear bearing 33 . The linear bearing 33 allows the pressing component 32 to move more smoothly and also prevents the pressing component 32 from swinging.

[0045] In some embodiments of the present invention, the jack 31 is a four-link screw scissor jack. The four-link screw scissor jack has a simple structure and a small volume, which helps to simplify the structure of the entire device and reduce the weight of the entire device.

[0046] like Figure 6As shown, in some embodiments, the four-link lead screw scissor jack includes a first articulated seat 311, a second articulated seat 312, a third articulated seat 313, a fourth articulated seat 314, a support arm assembly and a lead screw nut adjustment mechanism. The support arm assembly further includes a first support arm 315, a second support arm 316, a third support arm 317 and a fourth support arm 318. The top of the first hinge seat 311 is connected to the bottom surface of the top plate 22, the top of the first support arm 315 and the top of the second support arm 316 are hinged to the bottom of the first hinge seat 311, the bottom of the first support arm 315 and the top of the third support arm 317 are hinged to the side of the second hinge seat 312, the bottom of the second support arm 316 and the top of the fourth support arm 318 are hinged to the side of the third hinge seat 313, the bottom of the third support arm 317 and the bottom of the fourth support arm 318 are hinged to the top of the fourth hinge seat 314, and the bottom of the fourth hinge seat 314 is fixedly connected to the connecting portion 321. The first support arm 315 and the third support arm 317 are arranged opposite to each other in the vertical direction and form a V shape, and the second support arm 316 and the fourth support arm 318 are arranged opposite to each other in the vertical direction and form a V shape. The first hinge seat 311 and the fourth hinge seat 314 are vertically opposite to each other, and the second hinge seat 312 and the third hinge seat 313 are horizontally opposite to each other. The screw nut adjustment mechanism includes a hand wheel 3193, a screw 319, a reverse thread nut 3191 and a positive thread nut 3192. The reverse thread nut 3191 is inserted into the second hinge seat 312, the positive thread nut 3192 is inserted into the third hinge seat 313, the screw 319 is installed in the reverse thread nut 3191 and the positive thread nut 3192, and the hand wheel 3193 is installed at the end of the screw 319 and faces the third hinge seat 313. The screw 319 is driven to rotate by rotating the hand wheel 3193, and the screw 319 drives the two nuts to move closer to or away from each other, so that the fourth hinge seat 314 drives the pressing component 32 to move vertically. Of course, a limit ring 3194 can also be set in the middle of the screw 319 to limit the excessive movement of the two nuts. The screw 319 can preferably be a trapezoidal screw. In addition, two support arm assemblies can be set between the first articulated seat 311, the second articulated seat 312, the third articulated seat 313, and the fourth articulated seat 314, and the screw nut adjustment mechanism is located between the two support arm assemblies to make the four-link screw scissor jack more stable and reliable.

[0047] During the compression of the battery stack 8, as the amount of downward compression increases, the pressure generated becomes greater and greater. However, as the amount of downward compression increases, the angle between the first support arm 315 and the second support arm 316 becomes smaller and smaller, and the force acting on the lead screw 319 becomes smaller and smaller, so that the torque driving the lead screw 319 becomes smaller and smaller, and more and more labor-saving.

[0048] like Figure 2 and Figure 3As shown, in some embodiments of the present invention, a pressure sensor 4 capable of monitoring the pressure value of the jack 31 is provided between the jack 31 and the top plate 22, and a pressure display screen 5 is also provided on the top plate 22, and the pressure sensor 4 is connected to the pressure display screen 5 by signal.

[0049] Specifically, when the jack 31 presses the battery stack 8, the pressure sensor 4 can monitor the pressure value of the jack 31 and transmit the pressure value signal to the pressure display screen 5, and the pressure display screen 5 displays the pressure value of the jack 31 in real time. On-site workers can judge whether the pressure of the battery stack 8 is completely released or whether the packaging pressure of the battery stack 8 meets the standard by observing the pressure value on the pressure display screen 5.

[0051] Specifically, the support plate 6 is configured to be able to slide between the hoisting area and the positioning area, which can assist on-site workers in moving the battery stack 8 and reduce the labor burden of on-site workers.

[0052] like Figure 2 As shown, in some embodiments of the present invention, a plurality of limit blocks 63 capable of limiting the placement position of the battery stack 8 are provided on the top of the support plate 6 .

[0053] Specifically, the battery stack 8 can be placed between these limit blocks 63, which can limit the position of the battery stack 8. On the one hand, they can keep the battery stack 8 in a vertical position to facilitate compaction, and on the other hand, they can align the steel belt 83 on the battery stack 8 with the avoidance groove 323, thereby preventing the battery stack 8 from being displaced during the compaction process.

[0054] In some embodiments, the number of limit blocks 63 can be six, two of which are located on both sides of the length direction of the battery stack 8, two are located on one side of the width direction of the battery stack 8, and two are located on the other side of the width direction of the battery stack 8.

[0056] Specifically, align the through hole and the second limiting hole, and then insert the limiting rod 65 into the through hole and the second limiting hole to fix the support plate 6 in the hoisting area, so as to facilitate the placement of the discharge stack 8. Remove the limiting rod 65 from the through hole and the second limiting hole, and the support plate 6 can be moved. Insert the limiting rod 65 into the through hole and the first limiting hole to fix the support plate 6 in the positioning area, so as to facilitate the compression of the battery stack 8. Remove the limiting rod 65 from the through hole and the first limiting hole, and the support plate 6 can be moved.

[0057] like Figure 2 and Figure 3 As shown, in some embodiments of the utility model, the battery stack disassembly and assembly auxiliary device also includes a frame 7, the substrate 1 is installed on the top of the frame 7, and a plurality of running wheels 71 are installed at the bottom of the frame 7, and the battery stack disassembly and assembly auxiliary device can be moved with the help of the running wheels 71. And the height of the frame 7 is adjustable to facilitate the coordination of the battery stack disassembly and assembly auxiliary device with the lifting equipment. Of course, the frame 7 can be raised and lowered in any suitable manner, and the utility model does not limit it.
