Description

Technical Field

[0001] The present invention belongs to the technical field of new energy vehicle lithium battery production, and specifically relates to a lithium battery automatic encapsulation machine. Background Art

[0002] New energy vehicles refer to vehicles that use non-traditional energy as the power source. New energy vehicles drive the vehicle by adopting alternative energy sources such as electric energy and hydrogen energy, which have higher environmental protection and lower emissions, meeting the requirements of sustainable development. Currently, common new energy vehicles on the market all use lithium batteries as the energy source for driving.

[0003] Due to the very active chemical properties of lithium metal in new energy vehicle lithium batteries, the processing, storage, and use of lithium metal in new energy vehicles have very high environmental requirements. Currently, when producing and processing new energy vehicle lithium batteries, the outer shell and the encapsulation cover of the new energy vehicle lithium battery are usually processed separately, and then the encapsulation cover and the lithium battery outer shell are assembled, and sealant is applied at the joint between the encapsulation cover and the new energy vehicle lithium battery outer shell to make the encapsulation cover and the new energy vehicle lithium battery outer shell adhere and seal. Then, electrolyte solution is poured into the new energy vehicle lithium battery outer shell, and at the same time, charging detection is carried out to complete the encapsulation processing and production of the new energy vehicle lithium battery.

[0004] A patent with the publication number of CN220155579U discloses a lithium battery automatic encapsulation machine. By using the fact that the cross-section of the encapsulation table is "U" - shaped, the conveyor belt can shuttle inside the encapsulation table. By using the clamping component arranged on the top of the conveyor belt, the lithium battery body to be coated with glue can be clamped inside the clamping component. By using the grooves opened on both sides of the encapsulation table, the glue - coating component can be arranged inside the grooves. By using the telescoping of the glue - coating component, the surface of the lithium battery body located inside the encapsulation table can be coated with glue. By arranging the glue - coating components in both grooves, the surface of the cylindrical lithium battery body can be evenly coated with glue.

[0005] The above - mentioned solution still has some problems in practical applications. Usually, the battery sealing cover is docked and assembled with the outer shell of the new - energy vehicle lithium battery, and then sealing glue is coated at the docking part between the battery sealing cover and the outer shell of the new - energy vehicle lithium battery. After the sealing glue is coated, a scraper or a squeegee is used to smooth the coated sealing glue, so that the glue adheres and fixes the battery sealing cover and the outer shell of the new - energy vehicle lithium battery. Then, electrolyte liquid is injected through the filling port of the battery sealing cover. However, when coating the sealing glue at the docking part between the battery sealing cover and the outer shell of the new - energy vehicle lithium battery, usually, after coating the glue on one side of the outer shell of the new - energy vehicle lithium battery, a scraper or a squeegee is used to smooth it, and then the position of the outer shell of the new - energy vehicle lithium battery is adjusted, and glue is coated on the other side again, and then a scraper or a squeegee is used to smooth it. After continuously coating the glue around the new - energy vehicle lithium battery in turn, the packaging process of the new - energy vehicle lithium battery is completed. This not only has low efficiency but also is very cumbersome to operate.

[0015] Preferably, the coating and encapsulation assembly includes a spraying conduit installed on the lower end surface of the slider.

[0018] The beneficial effects of the present invention are as follows: 1. For the lithium battery automatic encapsulation machine of the present invention, the assembled lithium battery is installed on the placement tray, and the clamping and positioning assembly is driven to clamp and position the lithium battery housing. At the same time, the servo motor is started to drive the placement tray to rotate, thereby driving the lithium battery housing to rotate. During the process of driving the lithium battery housing to rotate, the coating and encapsulation assembly is driven to approach the interface between the lithium battery housing and the battery encapsulation cover. Then, the coating and encapsulation assembly is used to coat and seal glue at the interface between the lithium battery housing and the battery encapsulation cover, thus solving the problem that the existing lithium battery automatic encapsulation machine cannot drive the lithium battery housing to rotate while coating glue on it. After coating glue on one side of the lithium battery housing, a scraper or a squeegee is used to level it, and then the position of the lithium battery housing is adjusted, and glue is coated on the other side again. This not only has cumbersome operations but also greatly affects the battery encapsulation processing efficiency.

[0019] 2. An automatic lithium battery encapsulation machine according to the present invention drives a coating and encapsulation assembly to apply glue to the insertion and assembly part of the lithium battery housing and the battery encapsulation cover. At the same time, as the lithium battery housing is driven to rotate, a scraping block is used to level the applied glue. When coating the corners of the lithium battery housing, the corners of the lithium battery housing will squeeze the coating nozzle, causing the coating nozzle to push the telescopic conduit into the inner cavity of the telescopic groove and squeeze the spring in the inner cavity of the telescopic groove. Thus, the coating position can be adjusted according to the corners of the lithium battery housing to ensure the amount of glue applied, solving the problem that when the existing automatic lithium battery encapsulation machine applies glue to the docking part of the lithium battery housing and the battery sealing cover, if it is inconvenient to automatically adjust the position of the coating nozzle for the corners of the lithium battery housing, it will result in ineffective and uniform glue coating on the corners of the lithium battery housing, causing too little glue coating to affect the sealing performance of the lithium battery. On the contrary, too much coating will cause waste of glue, and too much glue flowing onto the surface of the lithium battery housing will require a large amount of time to clean it up.

[0020] 3. An automatic lithium battery encapsulation machine according to the present invention starts the hydraulic cylinder to drive the support plate to move downward, drives the T-shaped slide rod to move synchronously, and drives the pressing plate to move downward at the same time. Thus, the pressing plate presses the battery encapsulation cover, making the insertion and assembly of the battery encapsulation cover and the lithium battery housing tighter. At the same time, the pulling force of the tension spring is used to pull the T-shaped slide rod downward, thereby increasing the pressure of the T-shaped slide rod pushing the pressing plate against the battery encapsulation cover and improving the quality of the lithium battery housing encapsulation process. This solves the problem that when the existing automatic lithium battery encapsulation machine applies glue to the docking part of the lithium battery housing and the battery sealing cover, if the lithium battery housing and the battery sealing cover are not pressed to reduce the gap at the docking part, after the glue is applied and solidifies and expands, the gap between the lithium battery housing and the battery sealing cover will become larger, affecting the airtightness of the inner cavity of the lithium battery and causing liquid leakage after the electrolyte liquid is poured later.

Specific embodiments

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] Embodiment 1: As Figures 1 to 7 shown, a lithium battery automatic encapsulation machine according to an embodiment of the present invention includes a workbench 1, and a clamping and positioning assembly 3 is arranged on the upper end surface of the workbench 1; And the clamping and positioning assembly 3 includes a placement tray 31 rotatably connected to the upper end surface of the workbench 1. A plurality of cross limit grooves 38 are opened on the upper end surface of the placement tray 31, and a rotation groove 32 is opened at the bottom of the inner cavity of the cross limit groove 38. A plurality of T-shaped sliding columns 17 are slidably connected in the inner cavity of the rotation groove 32, and the T-shaped sliding columns 17 slide in the inner cavity of the cross limit groove 38. A clamping block 18 is installed at the upper end of the T-shaped sliding column 17; The placement tray 31 is used for placing the lithium battery housing 4. An installation seat 6 is installed at one end of the workbench 1. A hydraulic cylinder 7 is installed on the upper end of the installation seat 6. The piston rod end of the hydraulic cylinder 7 is fixedly connected to a support plate 8. A cross sliding groove 15 is opened on the upper end surface of the support plate 8. A slider 14 is slidably connected in the inner cavity of the cross sliding groove 15. A coating and encapsulation assembly 9 is installed on the lower end surface of the slider 14.

[0025] Specifically, the coating and encapsulation assembly 9 can adopt a caulking gun device. In the prior art, when applying sealing glue at the docking position between the battery sealing cover and the outer shell of a new energy vehicle lithium battery, usually after applying the glue on one side of the outer shell of the new energy vehicle lithium battery, a scraper or a squeegee is used to level it, and then the position of the outer shell of the new energy vehicle lithium battery is adjusted, and glue is applied to the other side again, and then a scraper or a squeegee is used to level it. After continuously applying glue to the four sides of the new energy vehicle lithium battery in turn, the encapsulation process of the new energy vehicle lithium battery is completed. This not only has a slow efficiency but also is extremely cumbersome to operate. In the present invention, the assembled outer shell 4 of the new energy vehicle lithium battery is integrally placed on the placement tray 31. At the same time, the T-shaped sliding column 17 is driven to slide and move closer to each other in the inner cavity of the cross-shaped limiting groove 38, and the T-shaped sliding column 17 drives the clamping block 18 to move synchronously, thereby positioning and clamping the outer shell 4 of the new energy vehicle lithium battery on the placement tray 31, so that the outer shell 4 of the new energy vehicle lithium battery is kept at the central position of the placement tray 31. Then, by starting the hydraulic cylinder 7 to drive the support plate 8 to move downward, and the support plate 8 drives the slider 14 to move synchronously. At the same time, the slider 14 drives the coating and encapsulation assembly 9 to approach the position of the outer shell 4 of the new energy vehicle lithium battery that needs to be encapsulated. Then, by driving the placement tray 31 to rotate, and the placement tray 31 drives the outer shell 4 of the new energy vehicle lithium battery to rotate synchronously. Thus, during the rotation of the outer shell 4 of the new energy vehicle lithium battery, the coating and encapsulation assembly 9 is used to apply sealing glue to the position of the outer shell 4 of the new energy vehicle lithium battery that needs to be encapsulated, thereby improving the encapsulation efficiency of the new energy vehicle lithium battery and solving the above problems.

[0026] As Figure 3 and Figure 7 shown, a rotating disk 33 is rotatably connected to the inner cavity of the rotating groove 32. A plurality of limiting sliding grooves 34 are formed on the upper end surface of the rotating disk 33. The T-shaped sliding column 17 is slidably connected to the inner cavity of the limiting sliding groove 34.

[0027] As Figure 3 and Figure 7 shown, a gear ring 37 is arranged on the lower end surface of the rotating disk 33. The gear ring 37 is externally engaged with a gear 35. A knob 36 is fixedly connected inside the gear 35, and the knob 36 is rotatably connected to the placement tray 31.

[0028] As Figures 1 to 2 shown, a battery encapsulation cover 5 is installed inside the upper end of the lithium battery outer shell 4. An anti-slip rubber pad is arranged outside the clamping block 18, and the clamping block 18 is used for positioning and clamping the lithium battery outer shell 4.

[0029] As Figure 1 and Figure 7As shown in the figure, a servo motor 20 is arranged inside the workbench 1. The output shaft end of the servo motor 20 penetrates through the workbench 1 and is fixedly connected to the placement tray 31. Hinges are fixedly connected to both sides of one end of the workbench 1, and a cabinet door 2 is fixedly connected to one end of the hinge.

[0030] Specifically, when processing and encapsulating the lithium battery of a new energy vehicle, the battery encapsulation cover 5 is docked and assembled with the lithium battery housing 4, and then the lithium battery housing 4 is installed on the placement tray 31. The knob 36 is driven to rotate, so that the knob 36 drives the gear 35 to rotate. At the same time, the gear 35 meshes with the transmission gear ring 37 to rotate. During the rotation of the gear ring 37, the rotating disc 33 will be driven to rotate. At the same time, the rotating disc 33 uses the limit sliding groove 34 to drive the T-shaped sliding columns 17 to move closer to each other. Then, the T-shaped sliding columns 17 slide and move closer to each other inside the cross limit groove 38. Then, the T-shaped sliding columns 17 drive the clamping blocks 18 to move synchronously, so that the clamping blocks 18 clamp and position the lithium battery housing 4. At the same time, the servo motor 20 is started to drive the placement tray 31 to rotate, and the placement tray 31 drives the lithium battery housing 4 to rotate. During the process of driving the lithium battery housing 4 to rotate, the coating and encapsulation assembly 9 is driven to approach the interface between the lithium battery housing 4 and the battery encapsulation cover 5. Then, the coating and encapsulation assembly 9 is used to coat and seal the glue at the interface between the lithium battery housing 4 and the battery encapsulation cover 5, thereby improving the efficiency of lithium battery encapsulation processing. Thus, it solves the problem that the existing lithium battery automatic encapsulation machine cannot drive the lithium battery housing to rotate while coating glue on it. After coating the glue on one side of the lithium battery housing, a scraper or a squeegee is used to level it, and then the position of the lithium battery housing is adjusted, and the glue is coated on the other side again. This not only has cumbersome operations, but also greatly affects the battery encapsulation processing efficiency.

[0031] Embodiment 2: As Figure 1 、 Figure 2 and Figure 7 shown, a T-shaped sliding rod 10 is slidably connected to the inside of one end of the support plate 8. A tension spring 11 is fixedly connected to the upper end surface of the support plate 8. One end of the tension spring 11 is fixedly connected to the T-shaped sliding rod 10. The lower end of the T-shaped sliding rod 10 is rotatably connected to a pressing disc 12.

[0032] As Figure 1 、 Figure 2 and Figure 7 shown, an electric push rod 16 is arranged on one side wall of the inner cavity of the cross sliding groove 15. The piston rod end of the electric push rod 16 is fixedly connected to the slider 14. A threaded joint 13 is arranged on the upper end surface of the slider 14.

[0033] Specifically, when applying glue for encapsulation at the interface between the lithium battery housing 4 and the battery encapsulation cover 5, the hydraulic cylinder 7 is activated to drive the support plate 8 to move downward, and the support plate 8 drives the T-shaped slide bar 10 to move synchronously. At the same time, the T-shaped slide bar 10 drives the pressing disc 12 to move downward, thereby pressing the battery encapsulation cover 5, making the insertion and assembly of the battery encapsulation cover 5 and the lithium battery housing 4 closer. Meanwhile, the pulling force of the tension spring 11 is used to pull the T-shaped slide bar 10 downward, thereby increasing the pressure of the T-shaped slide bar 10 pushing the pressing disc 12 against the battery encapsulation cover 5, improving the quality of the lithium battery housing encapsulation process. This solves the problem that in the existing lithium battery automatic encapsulation machine, when applying glue at the interface between the lithium battery housing and the battery sealing cover, if the lithium battery housing and the battery sealing cover are not pressed to reduce the gap at the interface, after the glue is applied and solidifies and expands, the gap between the lithium battery housing and the battery sealing cover will become larger, affecting the airtightness of the lithium battery inner cavity and causing liquid leakage after the electrolyte liquid is poured later.

[0034] As Figure 1 、 Figures 4 to 7 shown, the coating and encapsulation assembly 9 includes a spraying conduit 91 installed on the lower end face of the slider 14. An fixing plate 92 is fixedly connected to the outside of the spraying conduit 91. Two rotating shafts 94 are rotatably connected inside both ends of the fixing plate 92, and scraping blocks 96 are fixedly connected to the lower ends of the two rotating shafts 94.

[0035] As Figures 4 to 7 shown, two fixing cylinders 93 are fixedly connected to both ends of the fixing plate 92, and one end of the rotating shaft 94 is rotatably connected to the inner cavity of the fixing cylinder 93. A fixing disc 97 is fixedly connected to the outside of the rotating shaft 94. A torsion spring 95 is fixedly connected to the upper end of the fixing disc 97, and one end of the torsion spring 95 is fixedly connected to the inner wall of the fixing cylinder 93.

[0036] As Figure 4 and Figure 6 shown, a telescopic groove 21 is opened at one end of the spraying conduit 91. A plurality of springs 22 are fixedly connected to the bottom of the inner cavity of the telescopic groove 21, and a telescopic conduit 23 is fixedly connected to one end of the plurality of springs 22. One end of the telescopic conduit 23 is fixedly connected and communicated with a coating nozzle 19.

[0037] Specifically, when applying glue for encapsulation at the interface between the lithium battery housing 4 and the battery encapsulation cover 5, the hydraulic cylinder 7 is started to drive the support plate 8 to move downward, and the support plate 8 drives the T-shaped slide bar 10 to move synchronously. At the same time, the T-shaped slide bar 10 drives the pressing plate 12 to move downward, so that the pressing plate 12 presses the battery encapsulation cover 5, making the insertion and assembly of the battery encapsulation cover 5 and the lithium battery housing 4 tighter. Then, the electric push rod 16 is started to drive the slider 14 to slide in the inner cavity of the cross-shaped chute 15, and the slider 14 drives the spraying conduit 91 to move closer to the lithium battery housing 4. At the same time, the spraying conduit 91 drives the coating nozzle 19 to move synchronously. During the movement of the spraying conduit 91, it will drive the fixing plate 92 to move and drive the rotating shaft 94 to move synchronously. Thus, the rotating shaft 94 drives the scraping block 96 to contact the surface of the lithium battery housing 4. Then, the lithium battery housing 4 is driven to rotate, and at the same time, the external conveying pipe is connected through the threaded joint 13, so that the conveying pipe conveys the glue into the spraying conduit 91, and the coating nozzle 19 is used to apply glue to the insertion and assembly part of the lithium battery housing 4 and the battery encapsulation cover 5. Then, as the lithium battery housing 4 is driven to rotate, the scraping block 96 is used to level the applied glue. When coating the corners of the lithium battery housing 4, the corners of the lithium battery housing 4 will squeeze the coating nozzle 19, and the coating nozzle 19 will push the telescopic conduit 23 into the inner cavity of the telescopic groove 21 and squeeze the spring 22 in the inner cavity of the telescopic groove 21. Thus, the coating position can be adjusted according to the corners of the lithium battery housing 4 to ensure the amount of glue applied, thereby solving the problem that when the existing lithium battery automatic encapsulation machine applies glue at the interface between the lithium battery housing and the battery sealing cover, if it is inconvenient to automatically adjust the position of the coating nozzle for the corners of the lithium battery housing, it will result in ineffective and uniform glue coating on the corners of the lithium battery housing, causing too little glue coating to affect the sealing performance of the lithium battery. On the contrary, too much coating will cause waste of glue, and too much glue flowing onto the surface of the lithium battery housing will require a lot of time to clean it up.

[0038] Working principle: When processing and packaging lithium batteries, the battery packaging cover 5 is docked and assembled with the lithium battery housing 4, and then the lithium battery housing 4 is installed on the placement tray 31. Then, the knob 36 is driven to rotate, causing the knob 36 to drive the gear 35 to rotate. At the same time, the gear 35 meshes with and drives the toothed ring 37 to rotate. During the rotation of the toothed ring 37, the rotating disk 33 will be driven to rotate. At the same time, the rotating disk 33 uses the limit chute 34 to drive the T-shaped sliding columns 17 to move closer to each other. Furthermore, the T-shaped sliding columns 17 slide and move closer to each other in the inner cavity of the cross-shaped limit groove 38. Then, the T-shaped sliding columns 17 drive the clamping blocks 18 to move synchronously, so that the clamping blocks 18 clamp and position the lithium battery housing 4. At the same time, the servo motor 20 is started to drive the placement tray 31 to rotate, and the placement tray 31 drives the lithium battery housing 4 to rotate. During the process of driving the lithium battery housing 4 to rotate, the coating and packaging assembly 9 is driven to approach the interface between the lithium battery housing 4 and the battery packaging cover 5. Then, the coating and packaging assembly 9 is used to coat and seal glue at the interface between the lithium battery housing 4 and the battery packaging cover 5, thereby improving the efficiency of lithium battery packaging and processing; When coating and glue-sealing the interface between the lithium battery housing 4 and the battery packaging cover 5, the hydraulic cylinder 7 is started to drive the support plate 8 to move downward, and the support plate 8 drives the T-shaped sliding rod 10 to move synchronously. At the same time, the T-shaped sliding rod 10 drives the pressing disk 12 to move downward, so that the pressing disk 12 presses the battery packaging cover 5, making the plug-in assembly of the battery packaging cover 5 and the lithium battery housing 4 more tight. At the same time, the pulling force of the tension spring 11 is used to pull the T-shaped sliding rod 10 downward, thereby increasing the pressure of the T-shaped sliding rod 10 to push the pressing disk 12 against the battery packaging cover 5; When applying glue for encapsulation at the interface between the lithium battery housing 4 and the battery encapsulation cover 5, the hydraulic cylinder 7 is started to drive the support plate 8 to move downward, and the support plate 8 drives the T-shaped slide bar 10 to move synchronously. At the same time, the T-shaped slide bar 10 drives the pressing plate 12 to move downward, so that the pressing plate 12 presses the battery encapsulation cover 5, making the insertion and assembly of the battery encapsulation cover 5 and the lithium battery housing 4 closer. Then, the electric push rod 16 is started to drive the slider 14 to slide in the inner cavity of the cross chute 15, and the slider 14 drives the spraying conduit 91 to move closer to the lithium battery housing 4. At the same time, the spraying conduit 91 drives the coating nozzle 19 to move synchronously. During the movement of the spraying conduit 91, it will drive the fixing plate 92 to move and drive the rotating shaft 94 to move synchronously. Thus, the rotating shaft 94 drives the scraping block 96 to contact the surface of the lithium battery housing 4. Then, the lithium battery housing 4 is driven to rotate, and at the same time, the external conveying pipe is connected through the threaded joint 13, so that the conveying pipe transports the glue into the spraying conduit 91, and the coating nozzle 19 is used to apply glue to the insertion and assembly part of the lithium battery housing 4 and the battery encapsulation cover 5. Then, as the lithium battery housing 4 is driven to rotate, the scraping block 96 is used to level the applied glue. When coating the corner of the lithium battery housing 4, the corner of the lithium battery housing 4 will squeeze the coating nozzle 19, and the coating nozzle 19 will push the telescopic conduit 23 to slide into the inner cavity of the telescopic groove 21 and squeeze the spring 22 in the inner cavity of the telescopic groove 21. Thus, the coating position can be adjusted according to the corner of the lithium battery housing 4, ensuring the amount of glue applied and improving the quality of the lithium battery housing encapsulation process.
