[0032] The present application provides a packaging box, which can quickly replace the sealing ring at the top of the packaging box.

[0033] Reference Figures 1 to 6 The present embodiment relates to a packaging box, which comprises an upper box 1, a lower box 2 and a locking device 3. The upper box 1 is detachably connected with the lower box 2 through the locking device 3. The lower box 2 is internally provided with a first cavity 21 and a second cavity 22 for accommodating a battery. The upper box 1 is provided with a first through hole 11 and a second through hole 12 corresponding to the first cavity 21 and the second cavity 22. The lower box 2 is sealingly connected with a lifting platform (not shown in the figure). The upper end surface of the upper box 1 is provided with a first sealing groove 13 along the circumference of the first through hole 11 and the second through hole 12. A first sealing ring is arranged in the first sealing groove 13. The upper box 1 is sealingly matched with a turntable (not shown in the figure) through the first sealing ring.

[0034] In the secondary packaging process of the battery, the operator places the battery cell on the turntable. After starting the device, the turntable moves the battery cell to the packaging station, and then the upper sealing cover and the lifting platform of the lithium battery secondary packaging device move and are buckled at the same time, so that the upper chamber of the upper sealing cover and the first through hole 11 and the second through hole 12 of the upper box body 1 and the first chamber 21 and the second chamber 22 of the lower box body 2 form a sealed cavity. The bayonet of the lithium battery secondary packaging device is started and pierces the air bag, and the vacuumizing step is carried out. After the vacuum degree of the sealed cavity reaches the set range, the packaging device inside the cavity sealed cavity starts the packaging operation. After the packaging operation is completed, the upper sealing cover and the lifting platform of the secondary packaging device are reset, and the packaging is completed.

[0035] Among them, the packaging box is provided with a detachably connected upper box body 1 and a lower box body 2. In combination with the setting of the locking device 3, when the first sealing ring between the upper box body 2 and the turntable needs to be disassembled, the locking device 3 can be released, and the upper box body 1 can be directly disassembled from the battery secondary packaging device. Then replace the first sealing ring, so as to realize the technical requirement of quickly replacing the first sealing ring.

[0036] Referring to Figure 3 and Figure 4 , the lower end surface of the upper box body 1 of the embodiment is provided with a second sealing groove 14 along the circumference of the first through hole 11 and the second through hole 12, and a second sealing ring is arranged in the second sealing groove 14. The upper box body 1 and the lower box body 2 are sealingly matched through the second sealing ring. By arranging the second sealing ring between the upper box body 1 and the lower box body 2, the gap between the mating surfaces of the upper box body 1 and the lower box body 2 can be effectively sealed.

[0037] Referring to Figure 5 and Figure 6 , the lower end surface of the lower box body 2 of the embodiment is provided with a third sealing groove 23 along the circumference of the first chamber 21 and the second chamber 22, and a third sealing ring is arranged in the third sealing groove 23. The lower box body 2 is sealingly matched with the lifting platform through the third sealing ring. By arranging the third sealing ring, the gap between the mating surfaces of the lower box body 2 and the lifting platform can be effectively sealed.

[0038] In summary, the third sealing ring, the second sealing ring and the first sealing ring are arranged between the mating surfaces of the lower box body 2 and the lifting platform, the lower box body 2 and the upper box body 1, and the upper box body 1 and the turntable respectively in the embodiment. On the premise of ensuring the sealing of the first chamber 21 and the second chamber 22, the upper box body 1 can be disassembled to quickly replace the first sealing ring.

[0039] Referring to Figure 4 , Figure 5 and Figure 7The upper end surface of the lower box 2 is provided with a positioning column 24, and the lower end surface of the upper box 1 is provided with a positioning hole 15 corresponding to the position of the positioning column 24. The positioning hole 15 cooperates with the positioning column 24, so that the first through hole 11 and the second through hole 12 are respectively opposite to the first chamber 21 and the second chamber 22. By arranging the positioning column 24 and the positioning hole 15, the installation position of the upper box 1 on the lower box 2 can be quickly positioned, and the problem of deviation of the upper box 1 during subsequent pressing of the upper box 1 is avoided.

[0040] In addition, the positioning hole 15 is provided with two, and is arranged on the outer side of the second sealing groove 14, and the two positioning holes 15 are arranged on the center axis of the upper box 1. The positioning hole 15 is arranged on the outer side of the second sealing groove 14, so that the position of the positioning hole 15 is away from the second sealing groove 14, avoiding the interference between the positioning hole 15 and the second sealing groove 14, and avoiding the problem that air is left in the positioning hole 15 during the vacuumizing operation, causing poor vacuum degree.

[0041] Reference Figure 6 In the embodiment, the lower end surface of the lower box 2 is provided with a fixing hole 25, and a fixing pin is arranged on the lifting platform and embedded in the fixing hole 25 to fix the lower box 2. In addition, the fixing hole 25 is provided with a plurality of fixing holes 25, which are evenly distributed, and the fixing hole 25 is arranged on the outer side of the third sealing groove 23 and symmetrically arranged on the center axis of the lower box 2. On the basis of arranging the third sealing groove 23 and the third sealing ring on the lower end surface of the lower box 2, the connection strength between the lower box 2 and the lifting platform can be effectively improved by adding the fixing pin, so as to facilitate disassembly of the lower box 2 during later maintenance.

[0042] Reference Figure 1 And Figure 8 The locking device 3 includes an upper lock head 31, a lower lock seat 32, a lock sleeve 33 and a handle 34. The upper lock head 31 is fixedly arranged on the side surface of the upper box 1, the lower lock seat 32 is correspondingly arranged on the side surface of the lower box 2, the handle 34 is movably connected with the lower lock seat 32, the lock sleeve 33 is hinged with the handle 34, and when locking, the lock sleeve 33 is overlapped on the groove of the upper lock head 31, and the locking between the lock sleeve 33 and the upper lock head 31 is realized by inward buckling of the handle 34. The locking device 3 is provided with four, and two are symmetrically arranged on the opposite sides of the packaging box. By arranging multiple locking devices 3 and installing them on the opposite sides of the packaging box, the uniformity of the pressing force between the cooperation surface of the upper box 1 and the lower box 2 is improved, so that the second sealing ring forms uniform extrusion deformation, avoiding the leakage of local area. At the same time, the handle 34 is used as the operating tool of the operator, which has a simpler structure, is convenient to operate, and has a more stable locking pressure.

[0043] Reference Figure 6The lower box 2 is provided with a plurality of sealing rings, and the sealing rings are arranged on the outer wall of the lower box 2 and the inner wall of the upper box 3, and the sealing rings are arranged in the first cavity 21 and the second cavity 22.
