During the sliding process, the fixing frame 10 automatically sprays glue on the side of the battery pack through the limiting docking component, and during the sliding process of the fixing frame 10, the limiting docking component moves away from the battery pack while applying the glue, so that after the glue spraying is completed, the battery packs are completely bonded together. The purpose of this is that glue can be applied to multiple battery packs at the same time, and the battery packs are completely bonded together after the glue is applied. The battery packs can be assembled by standing still for a period of time to wait for the glue to solidify, which can effectively improve the assembly efficiency of the battery packs, and the limiting docking component can control the path of the sprayed glue, so that the battery packs are more firmly connected by the glue.

[0018] As a further solution of the present invention, the limit docking assembly includes a support plate 28, a support plate 28 is fixedly connected to the side wall of the fixed frame 10, an alignment shaft 26 is fixedly connected to the top of the support plate 28, an alignment block 24 is slidably sleeved on the top of the alignment shaft 26, and a first spring 27 for resetting the alignment block 24 is sleeved on the alignment shaft 26, a connecting groove 25 is provided on the fixed frame 10, and the connecting groove 25 and the support plate 28 are staggeredly arranged on both sides of the fixed frame 10, the bottom end of the hydraulic rod 4 is fixedly connected to the second base 7, and the second base 7 is fixedly arranged above the bottom plate 1, the output end of the hydraulic rod 4 is fixedly connected to the second fixed plate 8, the output shaft of the hydraulic rod 4 is fixedly connected to the first base 6, the top of the first base 6 is fixedly connected to the fixed cylinder 5, and the output end of the fixed cylinder 5 is fixedly connected to the first fixed plate 9, and the slide rail 11 is sleeved with a reset spring 12 for resetting the fixed frame 10; When the above scheme is put into actual use, when the hydraulic rod 4 pushes the fixing frame 10 to slide and dock the battery packs together, the hydraulic rod 4 is first started to drive the fixing frame 10 to compress the return spring 12 to slide through the second fixing plate 8. When the adjacent fixing frames 10 gradually contact, the alignment block 24 on the fixing frame 10 will contact the connecting groove 25 on the adjacent fixing frame 10, and with continuous squeezing, the alignment block 24 gradually slides into the inside of the connecting groove 25, so that the first spring 27 is compressed and slides downward. When the alignment block 24 completely enters the inside of the connecting groove 25, that is, the adjacent fixing frames 10 are completely fitted together, and the alignment block 24 no longer restricts the battery pack from both sides, at this time, the fixing cylinder 5 is started to drive the first fixing plate 9 to slide, and the first fixing plate 9 directly contacts the side wall of the battery pack, squeezing the battery pack to slide on the fixing frame 10, so that multiple battery packs are in contact and docked together.

[0019] As a further solution of the present invention, the sliding spraying assembly includes a rack rod 13, the rack rod 13 is fixedly arranged at the top of the bottom plate 1, the bottom end of the rack rod 13 is slidably connected with a positioning plate 23, the top of the positioning plate 23 is fixedly connected with a sliding shaft 20, the sliding shaft 20 is slidably connected with a connecting plate 21, one end of the positioning plate 23 is fixedly connected with a threaded rod 22, the threaded rod 22 is spirally connected with a transmission gear 17 meshing with the rack rod 13, and limit plates for limiting the sliding of the transmission gear 17 are arranged on both sides of the rack rod 13, the top of the connecting plate 21 is fixedly connected with a glue coating head 19, the input end of the glue coating head 19 is connected to the output end of the connecting pipe 2, one end of the connecting plate 21 is slidably connected with a sliding plate 16, the side wall of the fixed frame 10 is fixedly connected with a side plate 14, the side plate 14 is fixedly connected with a connecting shaft 15, the sliding plate 16 is slidably sleeved on the connecting shaft 15, and the top of the positioning plate 23 is fixedly connected with a cone plate 18; When the above scheme is put into actual use, when the fixing frame 10 slides on the slide rail 11, the glue in the glue storage barrel 3 enters the inside of the glue coating head 19 through the connecting pipe 2, and is then sprayed onto the side wall of the side plate 14 through the output end of the glue coating head 19. The positioning plate 23 slides synchronously along the rack rod 13, so that the transmission gear 17 meshes and rotates with the rack rod 13. The rotation of the transmission gear 17 drives the threaded rod 22 to slide, so that the positioning plate 23 slides on the rack rod 13 in the longitudinal and transverse directions, and the connecting plate 21 slides synchronously with the positioning plate 23. Due to the restriction of the cone plate 18, the connecting plate 21 will slide along the cone plate during the sliding process. 18 changes in height up and down, and the sliding of the connecting plate 21 drives the sliding plate 16 to slide up and down synchronously along the connecting shaft 15, so that the height of the glue coating head 19 on the top of the connecting plate 21 also changes, so that the glue sprayed by the glue coating head 19 can be more adhered to the battery pack, and with the continuous meshing and rotation of the transmission gear 17 and the rack rod 13, the positioning plate 23 gradually slides to one side of the fixing frame 10. At this time, the glue coating process of the battery pack by the glue coating head 19 has also been completed. At this time, the adjacent fixing frames 10 can also be fitted, thereby completing the spraying and docking of the battery pack, and the preliminary assembly of the battery pack is completed.

[0020] As a further solution of the present invention, the side walls of the cone plate 18 are all smooth walls, and the side walls of the sliding plate 16 are provided with inclined grooves that are horizontal to the side walls of the cone plate 18; When the above solution is put into practical use, when the sliding plate 16 slides along the outer wall of the cone plate 18, the friction between the sliding plate 16 and the cone plate 18 is smaller, and it is easier to slide.

[0021] As a further solution of the present invention, an antistatic coating is provided on the outer wall of the fixing frame 10; When the above solution is put into actual use, static electricity is more likely to be generated under the thrust of squeezing, thereby avoiding affecting the battery pack. The antistatic coating prevents the fixing frame 10 from being subjected to force and generating static electricity during movement.

[0022] As a further solution of the present invention, the outer wall of the slide rail 11 is a smooth wall, and the fixing frame 10 can be completely fitted with the outer wall of the slide rail 11; When the above solution is put into actual use, the fixing frame 10 that is completely fitted together will be more stable when sliding on the slide rail 11, and will not shake in other directions.

[0023] As a further solution of the present invention, one end of the first fixing plate 9 is fixedly connected to a silicone pad; When the above solution is put into actual use, the first fixing plate 9 is in direct contact with the side of the battery pack, and the silicone cushion plays a buffering role to prevent a large pressure from directly acting on the battery pack and affecting the battery pack.

[0024] Working principle: put the battery pack to be assembled into each fixing frame 10, start the hydraulic rod 4 to push the fixing frame 10 to slide, when the fixing frame 10 slides on the slide rail 11, the glue in the glue storage barrel 3 enters the inside of the glue coating head 19 through the connecting pipe 2, and then is sprayed onto the side wall of the side plate 14 through the output end of the glue coating head 19, the positioning plate 23 slides synchronously along the rack rod 13, so that the transmission gear 17 meshes and rotates with the rack rod 13, and the rotation of the transmission gear 17 drives the threaded rod 22 to slide, so that the positioning plate 23 moves on the rack rod 13 along the longitudinal and transverse directions. Sliding in two directions, the connecting plate 21 slides synchronously with the positioning plate 23. Due to the limitation of the cone plate 18, the connecting plate 21 changes up and down along the cone plate 18 during the sliding process. The sliding of the connecting plate 21 drives the sliding plate 16 to slide up and down synchronously along the connecting shaft 15, so that the height of the glue coating head 19 on the top of the connecting plate 21 also changes, so that the glue sprayed by the glue coating head 19 can be more attached to the surface of the battery pack. As the transmission gear 17 and the rack rod 13 are continuously engaged and rotated, the positioning plate 23 gradually slides to one side of the fixing frame 10; When the hydraulic rod 4 pushes the fixing frame 10 to slide and dock the battery packs together, the hydraulic rod 4 is first started to drive the fixing frame 10 to compress the return spring 12 to slide through the second fixing plate 8. When the adjacent fixing frames 10 gradually contact, the alignment block 24 on the fixing frame 10 will contact the connecting groove 25 on the adjacent fixing frame 10, and with continuous squeezing, the alignment block 24 gradually slides into the inside of the connecting groove 25, so that the first spring 27 is compressed and slides downward. When the alignment block 24 completely enters the inside of the connecting groove 25, that is, the adjacent fixing frames 10 are completely fitted together, and the alignment block 24 no longer restricts the battery pack from both sides. At this time, the fixing cylinder 5 is started to drive the first fixing plate 9 to slide, and the first fixing plate 9 directly contacts the side wall of the battery pack, squeezing the battery pack to slide on the fixing frame 10, so that multiple battery packs are in contact and docked together.
