Then, the two overturning tables 2 are driven to overturn upwards in opposite directions, the overturning tables 2 synchronously drive the aluminum plastic film 82 to stably overturn through the adsorption platform 21, in the overturning process, if the battery cell 81 is slightly deviated to one side in the width direction of the material table 11, the overturning table 2 positioned at the side can push the battery cell 81 to move to the other side, when the overturning table 2 is overturned to a vertical state, the battery cell 81 is basically positioned at the middle position of the material table 11, and the two lifting rollers 73 are just correspondingly positioned below the two lifted plates 321, and it is to be noted that in order to avoid the two overturning tables 2 from extruding the battery cell 81, the aluminum plastic film 82 is not completely extruded and tightly adhered to the two side surfaces of the battery cell 81.
Before edge sealing, the aluminum plastic film 82 can be lifted, pulled and tensioned upwards; specifically, the two adsorption platforms 21 firstly release the adsorption fixing effect on the aluminum plastic film 82, then start the second air cylinder 51, drive the two side clamping blocks 53 to slide away from each other, so that the side clamping blocks 53 move away from between the two edge sealing plates 42 to finish avoiding, meanwhile, the second air cylinder 51 drives the lifting piece 54 to move upwards, after a section of upward movement, the lifting plate 543 contacts with the contact plate 72, under the sliding fit of the hooking guide block 71 and the stroke seat 62, the lifting executing piece 7 integrally lifts, the lifting executing piece 7 correspondingly lifts the two lifted plates 321 through the two lifting rollers 73, the two sliding bottom frames 31 slide upwards, indirectly enable the moving pin 341 to move along the track groove 231, and when the moving pin 341 moves from the arc section of the track groove 231 to the vertical section, the two clamping roller frames 34 generate opposite approaching displacement in the horizontal direction, so that two ends of the aluminum plastic film 82 are clamped between the row of clamping rollers 35 and the side wall of the pressing contact plate 631, the shrinkage block 632 is horizontally extruded and shrunk, the two pressing contact blocks synchronously approach each other, the two ends of the aluminum plastic film 82 approach inward and naturally lean against two side surfaces of the battery cell 81, then the lifting executing piece 7 continuously rises under the state of keeping the battery cell 81 pressed, the row of clamping rollers 35 roll upwards, the two ends of the aluminum plastic film 82 are lifted and tensioned under the upward clamping driving force of the clamping rollers 35, the aluminum plastic film 82 is further wrapped and tightly stuck on the battery cell 81, and the plastic packaging effect of the aluminum plastic film 82 on the battery cell 81 is greatly improved by combining the material property of the aluminum plastic film 82. It should be noted that, the upward moving distance of the sliding bottom frame 31 is smaller than that of the jacking member 54, the upward pulling and tensioning distances of the two tensioning mechanisms 3 to the two ends of the plastic-aluminum film 82 are actually shorter, and the purpose of upward pulling and tensioning is only to ensure the compactness of the molded package, so that the plastic-aluminum film 82 is not pulled and deformed due to excessive pulling and excessive wrapping force is not formed on the battery cell 81.
Then, two first air cylinders 411 are synchronously started under the condition that lifting and clamping states are maintained at two ends of the aluminum plastic film 82, under the driving of two driving components 41, two groups of edge sealing plates 42 positioned on two overturning tables 2 move towards each other, two edge sealing plates 42 positioned on the same side of the battery cell 81 are close to the side wall of the battery cell 81 to carry out hot-press edge sealing on the aluminum plastic film 82, after the hot-press is maintained for a few seconds, under the driving of the two driving components 41 again, the two groups of edge sealing plates 42 are separated to retract and reset to an initial position, then, the two overturning tables 2 are overturned to a horizontal state, the lifted plates 321 are separated from the lifting rollers 73 in the overturning process, the sliding bottom frame 31 and the clamping roller frame 34 are reset under the pulling force of the tension spring 33, then, the pressing piece 63 is ascended and reset, the battery cell 81 is pressed and the lifting executing piece 7 ascends along with the whole stroke seat 62, and finally, the battery cell 81 subjected to one-time packaging is removed.
The invention provides aluminum plastic film packaging equipment for a solid battery, which is characterized in that when the solid battery cell 81 is packaged once, the traditional horizontal placement packaging is replaced by vertical placement of the cell 81, the structural layout of a turnover table 2 is arranged at two sides of a middle material setting table 11, the two turnover tables 2 are both provided with adsorption platforms 21 for adsorbing and fixing an aluminum plastic film 82, the aluminum plastic film 82 can be subjected to operations of flattening and fixing and stably and relatively turnover, synchronous centering edge sealing treatment can be realized through two edge sealing mechanisms 4 correspondingly arranged on the turnover tables 2, the problem of single-side edge sealing stress of the cell 81 in the prior horizontal placement condition is solved, the uniformity of the stress of the cell 81 is ensured to form protection, a side clamping mechanism 5 is arranged between the two turnover tables 2 for placing and positioning the cell 81, the packaging positioning is realized, the aluminum plastic film 82 is convenient to cut accurately in advance, the residual is reduced, meanwhile, the edge sealing plate 42 is convenient to carry out edge sealing operation on the cell 81 on the premise of ensuring effective sealing, the two sides of the cell 81 are improved, the edge sealing performance is improved, the cell 81 is tightly pressed by the corresponding to the tightening mechanism 6 when the turnover tables are arranged under the condition that the cell 81 is tightly pressed, and the cell 81 is tightly pressed by the tightening mechanism is arranged under the condition of the corresponding to the turnover table 2.
In summary, the device provided by the invention can ensure the uniformity of stress when the battery cell 81 is packaged, indirectly protect the battery cell 81, improve the molding and packaging compactness of the battery cell 81 by the aluminum-plastic film 82 through various modes such as packaging positioning, lifting and tensioning the aluminum-plastic film 82, and further reduce the influence of obvious packaging gaps on the mechanical buffering protectiveness, heat dissipation, battery module assembly difficulty, light weight and the like of the battery cell 81, and improve the overall quality and service life of the battery.
