Description

Technical Field

[0001] The utility model relates to the technical field of solid-state battery testing, in particular to a solid-state battery testing mold. Background Art

[0002] A solid-state battery is a battery that uses solid electrodes and a solid electrolyte. Compared with traditional liquid lithium-ion batteries, it has a higher energy density, a longer service life, and better safety.

[0003] After the solid-state battery is installed on the bracket, the battery shell is generally directly exposed to the external environment. If it encounters bad salt spray and rain weather, whether it will cause corrosion on the surface of the battery shell. Therefore, a salt spray test mold for the finished shell of the solid-state battery is needed.

[0004] Currently, for the existing salt spray test molds for the finished shells of solid-state batteries, since the shell sizes of each batch of solid-state battery products are different, and the sizes of the supporting grooves opened on the mold tray are all fixed sizes, and since the mold tray is mostly directly welded to the mold bracket, it is not possible to effectively and conveniently replace the mold tray with a supporting groove of the corresponding size, which mostly reduces the flexible applicability of the mold tray on the salt spray test mold for the finished shell of the solid-state battery.

[0005] In addition, for the existing salt spray test molds for the finished shells of solid-state batteries, most of them spray salt spray in a single direction onto the surface of the finished shell in the mold box, which greatly reduces the salt spray test efficiency of the salt spray test mold for the finished shell of the solid-state battery.

[0006] The above problems are widespread and urgently need to be improved. Content of the Utility Model

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0028] Referring to Figure 1-6 , a solid-state battery test mold includes a mold tray 6. A salt spray chamber 1 is provided outside the mold tray 6. A bottom plate 2 is provided below the salt spray chamber 1. A liquid storage tank 21 and a motor 3 are provided on the bottom plate 2. A liquid delivery pipe 22 and a salt spray pump 23 are provided on the salt spray chamber 1. A mist transmission chamber 13 and a drain pipe 11 are provided on the salt spray chamber 1. A spray pipe 5 is connected to the mist transmission chamber 13. A spray head 51 is provided on the spray pipe 5. A motor shaft 31 is provided on the motor 3. A rotating shaft 33 is provided on the motor shaft 31. A mounting seat 4 is provided on the rotating shaft 33. An outer shell body 60 and an insertion block 7 are provided on the mold tray 6. A clamping block 71 is provided on the insertion block 7. A stud 8 is provided on the mounting seat 4. A chamber door 12 is provided on the salt spray chamber 1. The related structures described in this patent are all made of high acid and alkali resistant materials.

[0029] The spray head 51 is an atomizing nozzle, which can atomize and spray high acid liquid.

[0030] The outer shell body 60 is the battery outer shell for solid-state batteries.

[0031] The outer wall of the motor shaft 31 is provided with a sealing sleeve 32 , which is arranged to be squeezed and rotated with the lower end side wall of the salt spray box 1 . The sealing sleeve 32 is made of acid- and alkali-resistant vulcanized rubber material to prevent leakage of the motor shaft 31 .

[0032] The mounting seat 4 is provided with a screw hole 41, a plug-in slot 42 and a clamping slot 43. The screw hole 41 is threadedly connected to the stud 8. The plug-in slot 42 is plugged into the plug-in block 7. The plug-in block 7 is provided with a slide groove 70. The slide groove 70 is slidably connected with the clamping block 71. The clamping slot 43 is clamped with the clamping block 71. A spring 9 is provided between the clamping block 71 and the slide groove 70. The spring 9 is made of stainless steel. When the plug-in block 7 is inserted into the plug-in slot 42, the spring 9 which is always in extrusion deformation will drive the clamping block 71 to quickly clamp into the clamping slot 43, thereby realizing quick installation.

[0033] An anti-wear head 82 is provided at one end of the stud 8 facing the plug-in block 7, and a column cap 81 is provided at one end of the stud 8 away from the plug-in block 7. The anti-wear head 82 is made of hard alloy steel, which improves the wear resistance and durability of the stud 8 when squeezed with the plug-in block 7.

[0034] The mold tray 6 is provided with a supporting groove 61 and a drainage hole 62. The inner wall of the supporting groove 61 is provided with a damping pressure pad 63. The damping pressure pad 63 is in extrusion contact with the outer wall of the shell body 60. The damping pressure pad 63 is made of polyurethane, is acid and alkali resistant, and can be damped and extruded and positioned with the outer wall of the shell body 60.

[0035] The upper end of the drainage hole 62 is a diffusion structure and is connected to the supporting groove 61 . The drainage holes 62 are in two groups symmetrically, with five holes in each group arranged longitudinally. The accumulated salt spray liquid will fall into the salt spray box 1 through the drainage holes 62 .

[0036] The spray tube 5 and the spray head 51 are a group, which are two symmetrical groups in total. The spray tube 5 is made of a stainless steel bellows. An adjustment ring 52 is provided on the spray head 51. The fingers are hooked into the adjustment ring 52 and twisted. Combined with the spray tube 5 made of a stainless steel bellows, the angle of the spray head 51 can be adjusted to achieve precise spraying toward the shell body 60.

[0037] Working mode: If it is necessary to replace the mold tray 6 with different sizes of the supporting grooves 61, first remove the outer shell body 60, then open the cabinet door 12, and then rotate the column cap 81 counterclockwise to drive the stud 8 to rotate counterclockwise. Through the threaded drive of the screw hole 41, the stud 8 is withdrawn from the screw hole 41. Then, laterally move the insertion block 7 outward until the locking block 71 exits the card slot 43. Then, move the mold tray 6 upward. When the insertion block 7 exits the insertion slot 42, the current mold tray 6 can be quickly removed. Then, take the mold tray 6 with another size of the supporting groove 61 and snap it onto the mounting seat 4. It is convenient to disassemble and replace the mold tray 6 with a supporting groove 61 of a matching size for different sizes of the outer shell body 60, thereby improving the flexible applicability of the mold tray 6 on the salt spray test mold for the finished shell of the solid-state battery.

[0038] Moreover, during the salt spray test, start the salt spray pump 23 and the motor 3. The motor 3 drives the mold tray 6 and the outer shell body 60 as a whole to rotate at a uniform speed horizontally. At the same time, the salt spray pump 23 pumps the highly acidic liquid in the liquid storage tank 21 into the salt spray pump 23 through the infusion tube 22, and then conveys it to the mist transmission cavity 13 and the spray tube 5. Finally, it is atomized through the spray head 51 and a full-range atomized salt spray is sprayed towards the outer wall surface of the outer shell body 60, improving the salt spray test efficiency of the salt spray test mold for the finished shell of the solid-state battery.

[0039] In addition, during the salt spray test, the accumulated salt spray liquid will fall into the salt spray box 1 through the drain hole 62 and can be discharged through the drain pipe 11 later to avoid the situation of salt spray liquid accumulating in the supporting groove 61.

[0040] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
