The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0030] Referring to Figure 1 and Figure 2 , the present application provides a vacuum packaging device, comprising: an upper die set 1 and a lower die set 2, the upper die set 1 comprising an upper die block 11 movable up and down, the periphery of the upper die block 11 being surrounded by an upper die frame 12, the lower die set 2 comprising a lower die block 21 movable up and down, the periphery of the lower die block 21 being surrounded by a lower die frame 22. The upper die set 1 and the lower die set 2 are correspondingly arranged and can approach or move away from each other to make the upper die frame 12 and the lower die frame 22 contact and seal or move away from each other, and the upper die block 11 and the lower die block 21 move towards or away from each other to seal or open the die cavity.

[0031] The upper mold frame 12 is arranged on the periphery of the upper mold 11, and the lower mold frame 22 is arranged on the periphery of the lower mold 21. When the upper mold set 1 and the lower mold set 2 are close to each other to move the upper mold 11 and the lower mold 21 to close the mold cavity, the upper mold frame 12 and the lower mold frame 22 contact to form a sealing structure arranged outside the upper mold 11 and the lower mold 21, thereby realizing a good sealing cavity, which is beneficial to improve the packaging effect and use safety of the battery, and has the characteristics of simple structure, low cost and efficient packaging.

[0032] Specifically, the lower mold set 2 is fixedly arranged, the upper mold set 1 is movable up and down to approach or move away from the lower mold set 2, and drives the upper mold frame 12 to approach or move away from the lower mold frame 22. The main structure of the lower mold set 2 and the lower mold frame 22 are fixedly arranged, and the lower mold 21 is movable up and down to realize mold closing or mold opening with the upper mold 11. On the basis of the fixed lower mold set 2, the upper mold set 1 moves towards or away from the lower mold set 2, and drives the upper mold 11 and the upper mold frame 12 to move towards or away from the corresponding lower mold 21 and lower mold frame 22, which can ensure the accuracy of mold closing and mold opening, and avoid misalignment caused by relative movement.

[0033] The upper mold set 1 is driven to move up and down by the first driving cylinder 3, the first driving cylinder 3 is installed on the fixed seat 4 and located above the upper mold set 1, and the upper mold set 1 is connected to the piston rod of the first driving cylinder 3. The upper mold set 1, the lower mold set 2 and the first driving cylinder 3 are all installed on the fixed seat 4, and the first driving cylinder 3 drives the upper mold set 1 to move towards or away from the lower mold set 2 to close or open the mold.

[0034] On the basis of the above structure, the upper mold set 1 comprises a fixed plate 13, the upper mold 11 is arranged below the fixed plate 13, the upper mold frame 12 is sealingly connected to the bottom end of the fixed plate 13 and arranged on the periphery of the upper mold 11, and the upper mold frame 12 and the fixed plate 13 approach the lower mold frame 22 to contact and form a sealing structure. The upper mold frame 12 and the fixed plate 13 move together when the upper mold set 1 moves up and down under the drive of the first driving cylinder 3, and the upper mold 11 can move up and down to realize mold closing or mold opening on the basis of the movement. It is worth noting that when the upper mold 11 and the lower mold 21 move towards each other to close the mold, the bottom end of the upper mold 11 is not lower than the bottom end of the upper mold frame 12, and the top end of the lower mold 21 is not higher than the top end of the lower mold frame 22, and it is necessary to ensure that when the upper mold 11 and the lower mold 21 contact to close the mold, the upper mold frame 12 and the lower mold frame 22 are disengaged to realize sealing.

[0035] In combination Figure 3The chamber of the sealing structure is externally connected to a vacuumizing device through the vacuumizing pipe 5, and the fixing plate 13 is provided with a pressure relief hole 131 which is in communication with the chamber of the sealing structure and can be opened or closed. The chamber of the sealing structure is vacuumized by the vacuumizing device through the vacuumizing pipe 5 to realize the vacuum packaging environment of the battery, and the pressure relief hole 131 needs to be closed before vacuumizing to ensure the airtightness, and the pressure relief hole 131 is opened to release pressure after the vacuum packaging of the battery is completed.

[0036] The fixing plate 13 is provided with an opening and closing mechanism corresponding to the pressure relief hole 131, and the opening and closing mechanism comprises a second driving cylinder 14 and a plugging piece 15. The plugging piece 15 is connected with the piston rod of the second driving cylinder 14, and the plugging piece 15 is adapted to the pressure relief hole 131.

When the mold is closed, the third driving cylinder 72 drives the positioning block 71 to pass through the corresponding through hole 61 to clamp and fix the battery, thereby ensuring the yield and efficiency of the vacuum packaging of the battery.

[0039] The number of the through holes 61 is equal to the number of the positioning blocks 71. According to the actual working condition, four through holes 61 and positioning blocks 71 are provided in the drawings of the present application, so that the vacuum packaging of four batteries can be realized at one time. The positioning block 71 is connected with the base through a linear bearing, so as to ensure that the positioning block 71 is stable and linearly passes through the through hole 61, and the movement of the positioning block 71 is prevented from deviating. The base is a component of the positioning assembly 7 for carrying the positioning block 71.

[0040] The pressure table 6 is provided with a heating rod 62, the pressure table 6 is provided with a boss 63, the through hole 61 is arranged on the boss 63, and the boss 63 surrounds the circumferential side of the workpiece. After the mold closing positioning is completed, the heating rod 62 heats the pressure table 6 and the boss 63, so as to realize the heat sealing of the battery. The heating rod 62 can be a copper rod, and the pressure table 6 and the boss 63 can also be copper materials, which have the characteristics of low cost and high heat sealing efficiency.

[0041] The boss 63 is connected with the fourth driving cylinder 64, and the fourth driving cylinder 64 drives the boss 63 to move up and down. The boss 63 surrounds the circumferential side of the battery, which can improve the heating area of the battery, thereby improving the heat sealing effect. The boss 63 realizes the up-and-down movable structure through the fourth driving cylinder 64, so as to be stored in the pressure table 6 in the idle state, thereby saving space.

[0042] Based on this, the packaging process of the battery vacuum packaging device is as follows:

[0043] In the mold opening state, the corresponding number of batteries are conveyed through the upper mold frame 12 and the lower mold frame 22 by using the conveying belt, after the conveying is completed, the first driving cylinder 3 drives the upper mold set 1 to move downward to contact the lower mold set 2 to close the mold, then the second driving cylinder 14 drives the blocking piece 15 to close the pressure relief hole 131, and the vacuum degree is determined according to the actual working condition, for example, it can be-80Kpa. Then the third driving cylinder 72 drives the upper and lower two groups of positioning blocks 71 to pass through the corresponding through holes 61 to clamp and fix the batteries, and the fourth driving cylinder 64 drives the boss 63 to surround the circumferential side of the corresponding battery, then heating is carried out by using the heating rod to realize the heat sealing of the battery. After the heat sealing is completed, the heating is turned off, the fourth driving cylinder 64 drives the boss 63 to retract, the third driving cylinder 72 drives the positioning block 71 to retract to release the battery, the second driving cylinder 14 drives the blocking piece 15 to retract to open the pressure relief hole 131, the first driving cylinder 3 drives the upper mold set 1 to move upward to open the mold, then the packaged battery is conveyed to the next process by using the conveying belt, so as to complete the vacuum packaging of the battery.
