Detailed Implementation Methods

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0034] Figures 1 to 6 show a structural diagram of a solid-state lithium battery packaging device according to an embodiment of the present invention, including a base 1, a slide rail 5, an adaptive scaling mechanism 100, a linkage mechanism 200, an outer frame 14, and a locking mechanism 400. The slide rail 5 is disposed on the base 1 and communicates with the feed end 2 and the discharge end 3 mounted on the base 1. The adaptive scaling mechanism 100 is disposed within the slide rail 5, and one end of the adaptive scaling mechanism 100 is connected to a rotating component arranged in the middle of the base 1. The adaptive scaling mechanism 100 automatically extends during the rotation of the rotating component. The linkage mechanism 200 is mounted on the feed end 2 and the discharge end 3. On the side, driven by an external motor, the actuator of the linkage mechanism 200 is slidably connected to the feed end 2 and the discharge end 3 respectively, and moves along the feed end 2 and the discharge end 3 before and after encapsulation; the outer frame 14 is set on the adaptive scaling mechanism 100, and a cover plate 19 is slidably installed on the top of the outer frame 14. The battery body 15 is set inside the outer frame 14, and an elastic clamping mechanism 300 is installed on the side of the battery body 15. A damper is built into the elastic clamping mechanism 300; the locking mechanism 400 is installed in the middle of the base 1, and the locking mechanism 400 cooperates with the adaptive scaling mechanism 100 to lock the rotating outer frame 14 and the cover plate 19.

[0035] In the specific implementation of this embodiment, during the packaging process, the adaptive scaling mechanism 100 and the linkage mechanism 200 cooperate to automatically load and unload the lithium battery. During the loading and transfer process, not only can the battery body 15 be pressed against, but the position of the battery body 15 can also be automatically fixed to ensure the stability of the packaged structure.

[0036] In one embodiment of the present invention, during use, the outer frame 14 and the cover plate 19 can be fixed by the adaptive scaling mechanism 100 and rotated under the drive of the rotating component. When the outer frame 14 and the cover plate 19 rotate, the battery body 15 is placed inside the outer frame 14, the locking mechanism 400 encapsulates the outer frame 14 and the cover plate 19, and the linkage mechanism 200 delivers the encapsulated lithium battery and sends the lithium battery to be encapsulated into the base 1.

[0037] As shown in Figures 1, 2 and 3, in a preferred embodiment of the present invention, the adaptive scaling mechanism 100 includes a movable plate 9 and a retaining plate 10 slidably installed in the slide rail 5, and a connecting rod 11 connecting the movable plate 9 and the retaining plate 10.

[0038] One end of the connecting rod 11 is fitted with a spring 12, and a stepped groove 13 for sliding of the abutment plate 10 is provided in the abutment plate 10.

[0039] A feeding plate 4 is installed inside the inlet end 2 and the outlet end 3. The outer side of the feeding plate 4 is higher than the inner side to facilitate the sliding of the lithium battery.

[0040] The inner side of the feeding plate 4 is a slope, and a discharge groove 6 is provided at the connection between the discharge end 3 and the base 1.

[0041] The rotating assembly includes a rotating shaft 7 installed in the base 1 and a transmission shaft 8 installed on the side of the rotating shaft 7, and the transmission shaft 8 is connected to the movable plate 9.

[0042] In the specific implementation of this embodiment, when the rotating shaft 7 rotates under the drive of the external motor, the transmission shaft 8, the movable plate 9, the abutting plate 10 and the connecting rod 11 rotate synchronously. When the movable plate 9 and the abutting plate 10 slide through the feed end 2 and the discharge end 3 in the slide rail 5, under the action of the spring 12, the abutting plate 10 slides outward along the connecting rod 11 and disengages from the slide rail 5. Under the action of the linkage mechanism 200, the outer frame 14 can be removed from the abutting plate 10. After the removal is completed, the movable plate 9 and the abutting plate 10 continue to rotate. When the abutting plate 10 passes the slope of the discharge end 3, the abutting plate 10 slides in the opposite direction along the connecting rod 11.

[0043] As shown in Figures 1 and 6, in another preferred embodiment of the present invention, the linkage mechanism 200 includes a connecting frame 30 mounted on the feed end 2 and the discharge end 3, a movable rod 31 rotatably mounted on the connecting frame 30, and a connecting rod 32 and a connecting rod 34 hinged to both ends of the movable rod 31.

[0044] The free end of the first connecting rod 32 is hinged to a push rod 33, which is slidably connected to the feed end 2. The free end of the second connecting rod 34 is hinged to a push rod 35, which is slidably connected to the discharge end 3. Both the first push rod 33 and the second push rod 35 are equipped with baffles at one end.

[0045] In the specific implementation of this embodiment, the movable rod 31 rotates under the drive of the external motor, and the connecting rod 32 and the connecting rod 34 swing in a plane under the drive of the movable rod 31, so that the push rod 33 slides along the feed end 2 and the push rod 35 slides along the discharge end 3. The push rod 33 is used to push the outer frame 14 onto the adaptive scaling mechanism 100, and the push rod 35 is used to push the outer frame 14 away from the adaptive scaling mechanism 100.

[0046] As shown in Figures 1 and 4, in another preferred embodiment of the present invention, the elastic clamping mechanism 300 includes a column 20 mounted on the cover plate 19, a limiting column 21 and a limiting rod 22 arranged on the same side of the column 20;

[0047] The inner side of the outer frame 14 is provided with a slot that cooperates with the limiting post 21 and the limiting rod 22;

[0048] The bottom of the outer frame 14 is symmetrically equipped with a support frame 17, and a spring 18 is sleeved on the support frame 17.

[0049] In the specific implementation of this embodiment, multiple heat dissipation plates 16 are provided between the outer frame 14 and the battery body 15 to facilitate heat conduction and avoid heat concentration. During use, the battery body 15 is placed inside the outer frame 14, and the cover plate 19 is installed on the outer frame 14. At the same time, when the cover plate 19 is subjected to external force, it pushes the column 20 to move. The limiting column 21 and the limiting rod 22 slide synchronously with the column 20, and the support frame 17 slides along the outer frame 14. During this process, the second spring 18 is subjected to force and undergoes elastic deformation to eliminate the shaking that the battery body 15 may cause during the clamping process. In addition, a triangular cone can be provided inside the outer frame 14, and the free end of the insertion rod 23 is provided with a groove that cooperates with the triangular cone so that after the insertion rod 23 is inserted, the end expands and clamps the limiting rod 22 to achieve self-locking.

[0050] As shown in Figure 1, in another preferred embodiment of the present invention, the locking mechanism 400 includes a fixed rod 24 mounted on the base 1 and an arc-shaped rod 25 mounted on the top of the fixed rod 24;

[0051] The fixing rod 24 consists of a fixing pile and a V-shaped rod arranged at the top of the fixing pile.

[0052] In the specific implementation of this embodiment, when the outer frame 14 and the cover plate 19 rotate under the push of the adaptive scaling mechanism 100, when the cover plate 19 passes the arc rod 25, the cover plate 19 is subjected to external force and slides along the outer frame 14.

[0053] As shown in Figures 1 and 5, in another preferred embodiment of the present invention, the locking mechanism 400 includes a vertical rod 26 and a horizontal rod 27 mounted on a fixed stake, a receiving box 28 mounted on the vertical rod 26 and the horizontal rod 27, and a plug rod 23 disposed in the receiving box 28.

[0054] Both the vertical rod 26 and the horizontal rod 27 are provided with abutting members 29 on the side of the receiving box 28, which are used to push the insertion rod 23 inside the receiving box 28 to move.

[0055] In the specific implementation of this embodiment, when in use, the fixing rod 24 is neatly placed in the receiving box 28. When the closed outer frame 14 and cover plate 19 pass through the crossbar 27 and the receiving box 28 respectively, the clamping member 29 works to push the insertion rod 23 at the bottom of the receiving box 28 to move, push it out and embed it into the outer frame 14 and cover plate 19, and fix the position of the outer frame 14 and cover plate 19.

[0056] In summary, the battery body 15 is placed inside the outer frame 14, and the cover plate 19 is placed at the top of the outer frame 14. The outer frame 14 slides along the feeding plate 4. When it slides to the end of the feeding plate 4, the movable rod 31 rotates, causing the connecting rod 32 to swing. The connecting rod 32 pulls the push rod 33 to slide along the feed end 2, pushing the outer frame 14 onto the movable plate 9 and the pressing plate 10. The rotating shaft 7, the transmission shaft 8, the movable plate 9, and the pressing plate 10 rotate synchronously. When the outer end of the pressing plate 10 passes the slope of the feeding plate 4, the pressing plate 10 slides inward along the connecting rod 11 to fix the position of the outer frame 14. The cover plate 19 slides downward under the pressure when it passes the arc rod 25. The limiting post 21 and the limiting rod 22 slide synchronously with the column 20. The support frame 17 slides along the outer frame 14. The spring 18 undergoes elastic deformation under the force. The movable plate 9 and the pressing plate 10 slide through the slide rail 5. When the receiving box 28 is in use, the clamping member 29 works sequentially from the inner and outer sides of the cover plate 19 to push the insertion rod 23 at the bottom of the receiving box 28 to move, pushing it out and embedding it into the outer frame 14, the cover plate 19 and the limiting rod 22, fixing the position of the outer frame 14 and the cover plate 19. When the outer frame 14 and the cover plate 19 pass the discharge end 3, the clamping plate 10 slides outward under the action of the spring 12, releasing the constraint on the outer frame 14. At the same time, the movable rod 31 swings, and the packaged lithium battery is pushed out of the discharge slot 6 through the set push rod 35. In this application, during the packaging process, the adaptive scaling mechanism 100 and the linkage mechanism 200 cooperate to automatically load and unload the lithium battery. During the transfer process after loading is completed, not only can the clamping work of the battery body 15 be realized, but the position of the battery body 15 can also be automatically fixed to ensure the stability of the packaged structure.
