Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of core shaping equipment, in particular to a core hot pressing tool. Background Art
[0002] Hot pressing of lithium-ion battery cores is a process that, under certain temperature and pressure, shapes the battery cells and reduces their elasticity. This process is used to improve the flatness of lithium-ion batteries, eliminate separator wrinkles, and ensure a close fit between the separator and the positive and negative electrodes. This increases the qualified rate of core assembly and ensures the consistency of the thickness of the finished battery cells. In addition, hot pressing can also shorten the diffusion distance of lithium ions and reduce the internal resistance of the battery.
[0003] The existing core hot pressing tooling is tightly integrated with the hot press through the bottom, and the installation time is long. If the hot pressing tooling is accidentally touched during the production process, some of its parts are prone to dislocation or detachment, resulting in accidental deformation and damage due to inaccurate installation and positioning of the hot pressing tooling during subsequent hot pressing. At the same time, there is a lack of buffer between the core and the hot pressing tooling, which can easily cause accidental damage to the core and the hot pressing tooling. Utility Model Content

[0031] Example 1
[0032] See Figures 1-6 , including a hot pressing tooling 1, the hot pressing tooling 1 includes a sliding limit block 11, a main frame 12, a film 14, a sliding limit frame 15, a fixing bolt 16, a sliding positioning column 17 and an elastic component 18. The film 14 is a PE film, which has the characteristics of withstanding the high temperature of the core hot pressing and preventing adhesion. There are two sliding limit blocks 11 and they are symmetrical along the sliding direction of the sliding limit frame 15. A downward groove is provided in the middle of the top of the sliding limit block 11, and a groove of the same length and depth is also provided at the corresponding position on the side of the main frame. The sliding positioning column 17 penetrates the sliding limit block 11 to achieve a fixed connection and is plugged into the main frame 12. A groove is provided on the outside of the sliding limit block 11, and the groove and the corresponding position on the horizontal inside of the main frame 12 are connected using the elastic component 18, and the elastic component 18 is a spring or a rubber column. The main frame 12, the film 14 and the sliding limit frame 15 are stacked up and down and connected through with the fixing bolt 16.
[0033] The hot pressing tool 1 also includes a handle 13, an upward groove is provided in the middle of the side edge of the handle of the main frame 12, a connecting block with the same width as the groove is provided at the front end of the handle 13, the fixing bolt 16 passes through the main frame 12 and is connected to the connecting block, a downward protrusion is provided below the connecting block at the front end of the handle (13), and the height of the connecting block and the protrusion is the same as the height of the groove on the side of the handle of the main frame 12.
[0034] The main frame 12 protrudes downward at both ends of the side edges close to the handle 13, and is provided with grooves upward away from the side edges of the handle 13. The film 14 and the sliding limit frame 15 are provided with upward protrusions away from the side of the handle 13, and the height of the protrusions is the same as the depth of the grooves on the edges of the main frame 12 and the handle 13.
[0035] The press 2 used for the hot pressing tooling 1 includes a hot pressing platform 21, a limit block 22, a limit column 23 and a hot pressing slider 24. The limit block 22 and the limit column 23 are fixedly connected to the hot pressing platform 21, and the hot pressing slider 24 moves up and down along the limit column 23.
[0036] A rectangular block is provided on the upper surface of the limit block 22 corresponding to the lower surface of the hot pressing slider 24 . The inner width of the sliding limit frame 15 is the same as that of the limit block 22 . The winding core 3 is located between the sliding limit blocks 11 .
[0037] When the core is hot-pressed, the hot-pressing tool 1 slides and is clamped on the upper surface of the limit block 22 by relying on the inner slot of the sliding limit frame 15, and the downward protrusion of the front end of the handle 13 and the downward protrusions at both ends of the side edge of the main frame 12 near the handle 13 jointly press against the side of the limit block 22 to prevent the hot-pressing tool from sliding forward. The core 3 is located between the sliding limit block 11 and above the film 14. When the hot-pressing slider 24 moves downward along the limit column 23 to press the core, the core 3 undergoes lateral deformation and squeezes the sliding limit block, and the elastic component 18 between the sliding limit block 11 and the main frame 12 is compressed, and the sliding limit block 11 approaches the main frame 12 along the insertion direction of the sliding positioning column 17, thereby buffering the deformation of the core 3. When the core 3 is taken out, the deformation of the elastic component 18 is restored, driving the sliding limit block 11 and the sliding positioning column 17 to return to their initial position.
[0038] Finally, it should be noted that the above embodiments are only preferred embodiments of the present invention, which are only used to illustrate the technical solution of the present invention and are not limiting. Any modifications, improvements, other modifications or equivalent replacements made to the technical solution of the present invention by ordinary technicians in this field, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be included in the scope of protection of the present invention.
