Description
Technical Field
[0001] The present invention relates to the technical field of lithium batteries, and in particular to packaging equipment for producing solid electrolyte lithium batteries. Background Art
[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream. With the continuous advancement of science and technology, the application prospects of solid-state batteries are becoming more and more broad. In the future, solid-state batteries will be widely used in electric vehicles, smart phones, wearable devices and other fields. At the same time, with the continuous advancement of technology, the cost of solid-state batteries will continue to decrease, further promoting their application and development.
[0003] Solid electrolyte is the core component of solid-state batteries. It is responsible for conducting ions inside the battery. Compared with traditional liquid electrolytes, solid electrolytes have higher ionic conductivity, wider electrochemical window and better safety. At present, solid electrolytes are mainly divided into two categories: polymer electrolytes and inorganic solid electrolytes. Polymer electrolytes have the advantages of good processability, low cost and flexibility, but low ionic conductivity; while inorganic solid electrolytes have high ionic conductivity, wide electrochemical window and good mechanical properties, but high cost and difficult processing.
[0004] In the packaging of lithium batteries, the stacked batteries need to be packaged to protect the batteries from interference and damage from the external environment. The whole process needs to control other factors such as the tightness and airtightness of the packaging to ensure the safety and stability of the battery. For the packaging of solid-state batteries, soft-pack packaging is mostly used. Because the aluminum-plastic film shell of the soft-pack battery is not hard, when the battery loses heat and runs away, it will generally expand and break through the aluminum-plastic film package, taking away a large amount of heat and avoiding battery explosion.
[0005] Currently in the packaging process, the battery needs to be placed in a cut aluminum-plastic film shell after lamination, and then the edges are sealed by a heat sealer. However, during the heat sealing process, the equipment will contact the aluminum-plastic film shell on the top wall of the lithium battery, and the heat conduction will cause the adhesive in the aluminum-plastic film to contact and stick to the lithium battery. There is also a situation where the lithium battery placement position is offset during the heat sealing process, and there is a gap at the heat sealing position, which reduces the packaging quality of the lithium battery. Therefore, we urgently need a packaging equipment for solid electrolyte lithium battery production to solve the above problems. Summary of the invention

[0084] The output end of the hydraulic cylinder 1311 is fixedly connected to the U-shaped frame 1312, the U-shaped frame 1312 is rotatably connected to the roller 1313 through the bearing hole, the roller 1313 is fixedly connected to the heater 1314, the roller 1313 is fixedly connected to the heating plate 1315, the U-shaped frame 1312 is fixedly installed with the auxiliary roller 1317, the heater 1314 is located on the roller 1313, the roller 1313 is long, and the heater 1314 is located on the roller 1313. The second roller 1314 is a long strip, and the second heater 1314 is a conventional heating element. It is worth noting that the second heater 1314 and the second heating plate 1315 are both sleeved on the second roller 1313, and the second heating plate 1315 is located in the middle of the second roller 1313. The second heater 1314 is located on the second roller 1313 and on the outside of the second heating plate 1315, and the height of the second heating plate 1315 is higher than the height of the second heater 1314. When the second heater 1314 is started, The heat will be transferred to the heating plate 1315, so that the heating plate 1315 is heated up for the subsequent edge sealing process. The U-shaped frame 1312 has rotating rods extending from the opposite sides. The auxiliary roller 1317 is rotatably connected to the rotating rod. Therefore, the auxiliary roller 1317 is the auxiliary roller 1317 body and the rotating rod for its rotation. The rotating rod is connected to the U-shaped frame 1312. Therefore, the auxiliary roller 1317 can be rotated on the U-shaped frame 1312. Rotation. During the edge sealing process, the aluminum-plastic film will be deformed around the edge sealing due to heat. The auxiliary roller 1317 is used to rotate with the roller 1313 to flatten the aluminum-plastic film. The U-shaped frame 1312 is slidably connected to the auxiliary frame 1316 through a sliding rod. The auxiliary frame 1217 and the auxiliary frame 1316 are equipped with built-in telescopic cutting knives. The telescopic cutting knife is used to cut the excess position after the secondary heat sealing and the vacuum treatment after the primary heat sealing.
[0085] The vacuum assembly 14 includes a double-headed hydraulic cylinder 141, which is fixedly connected to the frame 6. The output end on the right side of the double-headed hydraulic cylinder 141 is fixedly connected to an inflator 142, to which a toggle plate 143 is fixedly connected, and an inflatable airbag 144 is provided on the toggle plate 143, and the open end of the inflatable airbag 144 is fixedly connected to the inflator 142. The output end on the left side of the double-headed hydraulic cylinder 141 is fixedly connected to a vacuum pump 145, and the vacuum pump 145 is fixedly connected to an exhaust nozzle 146. The toggle plate 143 and the inflatable airbag 144 provide a gap between the upper surface of the lithium battery and the aluminum-plastic film when the lithium battery is sealed at the inlet and outlet sides, thereby solving the problem that the heat melts the PP film in the aluminum-plastic film on the top of the lithium battery and causes contact with the lithium battery.
[0086] When the packaging equipment for solid electrolyte lithium battery production is working, the operator places the solid lithium battery in the aluminum-plastic film, and the driving guide rail 91 on the processing table 2 drives the placing plate 5 on the driving block 92 to move toward the operator. After the operator places the aluminum-plastic film with the solid lithium battery on the placing plate 5, the negative compressor 112 on the placing plate 5 is started, and the input end of the negative compressor 112 introduces wind from top to bottom. Because the ventilation plate 113 is located in the rectangular groove 111, and the input port of the negative compressor 112 is connected to the inner wall of the rectangular groove 111 through a connecting pipe, when the negative compressor 112 is started, the wind will pass through the ventilation plate 113 and then be discharged through the negative compressor 112. Therefore, when the negative compressor 112 is started, a negative pressure effect will be formed on the surface of the ventilation plate 113 to adsorb the bottom of the aluminum-plastic film. Figure 13-15 As shown, it can be clearly seen that the specific structure of the ventilation plate 113 is a plate with a grid-like air inlet in the middle. The air inlet is a plurality of through holes formed by the staggered composition of a plurality of long strips and horizontal strips. The air inlet is located directly above the negative compressor 112. The negative compressor 112 is fixedly connected to the inner wall of the placement plate 5 through a connecting pipe. Therefore, when the negative compressor 112 is started, wind will flow downward through the air inlet and be discharged through the output port of the negative compressor 112, thereby forming a negative pressure adsorption effect on the ventilation plate 113. As mentioned above, the size of the air inlet on the ventilation plate 113 is smaller than the size of the lithium battery. When the lithium battery is placed on the ventilation plate After the negative pressure machine 112 is on, its air inlet position will be completely covered. Therefore, when the negative pressure machine 112 is started, negative pressure will be formed in the rectangular groove 111, thereby adsorbing the lithium battery on the ventilation plate 113. The lithium battery here includes an aluminum-plastic film. The lithium battery is located in the aluminum-plastic film at this time. Therefore, the negative pressure adsorption is actually the bottom of the aluminum-plastic film. After adsorption, the driving block 92 will drive the driving guide rail 91 to move toward the processing area, and the hydraulic cylinders 114 on both sides drive the connecting rod 115 to move toward the direction of the solid-state lithium battery, driving the two driving blocks 117 on the guide rail 116 to move relatively. Fig.12, the driving guide rail three 116 is installed on the connecting rod 115, that is, the two driving guide rails three 116 are also located on the connecting rods 115 on the left and right sides. At this time, the front and rear sides of the two driving guide rails three 116 are slidably connected with two driving blocks three 117, and the driving blocks three 117 are fixedly connected to the limiting plates 118. At this time, the number of limiting plates 118 on the single driving guide rail three 116 is two, and the position of the following driving block three 117 is also located on the front and rear sides of the driving guide rail three 116. When the driving guide rail three 116 is started, the two driving blocks three 117 on the single driving guide rail three 116 will move relatively. Therefore, when the driving block three 117 When the relative movement is performed, the limiting plate 118 will also be driven to move relatively. The driving guide rail 3 116 is an electric driving guide rail and has two tracks. Therefore, two driving blocks 3 117 can be set on the driving guide rail 3 116 for relative movement. The driving guide rail 3 116 makes the two limiting plates 118 contact with the corresponding aluminum-plastic film and complete the clamping. Before clamping, the limiting plug rod 1112 on the corresponding limiting plate 118 will be plugged into the limiting slot 1111, so that the limiting plate 118 is combined together, and cooperates with the protective pad 2 1113 to complete the wrapping limit of the concave position of the aluminum-plastic film, that is, the limit of the solid-state lithium battery;
[0087] After the limiting is completed, the height of the rectangular frame 122 is adjusted by the hydraulic cylinder 2 121, and the aluminum-plastic film needs to be heat-sealed in the area above the auxiliary frame 1217 and in contact with it. The driving motor 129 installed on the frame 128 of the mounting block 127 will drive the transmission rod 1210 to rotate, so that the roller 1213 is in a vertical state, and the heating plate 1215 on the roller 1213 is driven by the hydraulic cylinder 3 1211 to contact the aluminum-plastic film, and the auxiliary roller 1216 is also in contact with the aluminum-plastic film. The driving guide rail 2 101 drives the driving block 2 102 to move downward, and the auxiliary frame 2 1316 is in contact with the aluminum-plastic film above. Driven by the driving motor 2 138, the roller 2 1313 is in a vertical state and moves downward through the hydraulic cylinder 4 1311, so that the heating plate 2 1315 on the roller 2 1313 is in contact with the aluminum-plastic film. The second wheel 1317 contacts the aluminum-plastic film, and through the driving of the driving block 4 124 on the driving guide rail 4 123 and the driving block 5 133 on the driving guide rail 5 132, the heating plate 1215 on the roller 1213 and the heating plate 2 1315 on the roller 2 1313 are driven to rotate. The heating plate 1215 and the heating plate 2 1315 are heated by the corresponding heater 1214 and the heater 2 1314. The current process is to heat-seal the side of the aluminum-plastic film once. When heat-sealing the side, the double-headed hydraulic cylinder 141 will drive the two ends of the inflator 142 and the vacuum pump 145 to move toward the direction of the lithium battery, and the toggle plate 143 extends into the top of the lithium battery to separate the top of the lithium battery from the aluminum-plastic film. The inflator 142 inflates the inflatable airbag 144 to increase the interval, and the suction nozzle 146 also extends into the aluminum-plastic film. When the side is heat-sealed, the vacuum pump 146 is attached to the aluminum-plastic film. Figure 1 As an example, after the lithium battery is placed, the left and right sides of the aluminum-plastic film covering the lithium battery are described as the side edges here, the inflator 142 is retracted by the drive of the output end of the double-head hydraulic cylinder 141, and the heating plate 1215 and the heating plate 2 1315 are heat-sealed on the top edge by the drive of the drive block 4 124 and the drive block 5 133 to attach Figure 1 Taking the figure as an example, after the lithium battery is placed, the rear side of the aluminum-plastic film covering the lithium battery is the top edge. Because the bottom edge of the aluminum-plastic film is sealed, the opening positions of the aluminum-plastic film covering the lithium battery are the left and right sides and the back side. Here, the left and right sides are the sides, and the back side is the top edge. At this time, the suction nozzle 146 is also heat-sealed into the aluminum-plastic film. At this time, the vacuum pump 145 is started to extract the air in the aluminum-plastic film, and the roller 1 1213 and the roller 2 1313 located on the outside are reset under the drive of the drive motor 1 129 and the drive motor 2 138 respectively, so as to attach Figure 4 Combined with the attached Figure 7For example, the outer position described here is the side away from the ventilation plate 113. When the roller 1 1213 and the roller 2 1313 corresponding to the outer position move, the positions of the roller 1 1213 and the roller 2 1313 are located at the primary heat sealing position of the aluminum-plastic film, and the roller 1 1213 and the roller 2 1313 located on the inner side are driven by the drive motor 1 129 and the drive motor 2 138 to move to attach Figure 4 Combined with the attached Figure 7 For example, the inner position described here is the side close to the ventilation plate 113, when the roller 1 1213 and the roller 2 1313 corresponding to the inner position move, the positions of roller 1 1213 and roller 2 1313 are located at the secondary heat sealing position of the aluminum-plastic film, and the above-mentioned primary heat sealing operation is repeated, and the secondary heat sealing is an overall seal. When the heat sealing is completed, the telescopic cutting knives on the auxiliary frame 1 1217 and the auxiliary frame 2 1316 cut the aluminum-plastic film to retain the area after the secondary heat sealing. At this time, the vacuum nozzle 146 is located on the outside and is reset by the double-headed hydraulic cylinder 141, thereby completing the packaging of the solid-state lithium battery.
[0088] After the first heat seal, the exhaust nozzle 146 is located inside the aluminum-plastic film. When the second heat seal is performed, the exhaust nozzle 146 is still a certain distance away from the edge sealing position of the second heat seal. Therefore, when the telescopic cutting knife cuts the aluminum-plastic film after the second heat seal, the exhaust nozzle 146 will not be cut.
[0089] It is worth noting that since the driving guide rail four 123 and the driving guide rail five 132 are conventional technical structures, and the driving guide rail four 123 and the driving guide rail five 132 are rectangular guide rail structures, the running trajectories of the driving block four 124 and the driving block five 133 both move in a rectangular path.
