Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0026] Example 1:

[0027] like Figure 1-6As shown, this utility model provides a portable pressure-display integrated large battery mold for solid-state batteries, comprising: a support mechanism and a pressurizing mechanism; the support mechanism includes a base plate 1, a U-shaped support frame 2 mounted on the base plate 1, and a rotatable handle 16 mounted on the support frame 2; the pressurizing mechanism includes a first lifting component, a second lifting component, and a pressure display component; the first lifting component includes a lifting cylinder 3 mounted on the base plate 1, the structure of which can refer to the structure design of a hydraulic cylinder, and its overall height can be adjusted; a manual pump 5 is mounted on the top of the support frame 2, the manual pump 5 being an air pump or a hydraulic pump, and the manual pump 5 is connected to the lifting cylinder 3 through a pipe, thereby raising the lifting cylinder 3 by manually pressing the manual pump 5; a support plate 4 is slidably mounted on the support frame 2, and the top of the support plate 4 has a groove adapted to the shape of the solid-state battery (the support plate 4 is used as a mold). The shape of the groove is not limited. The bottom of the support plate 4 contacts the top of the lifting cylinder 3. When the lifting cylinder 3 rises, the support plate 4 rises. The solid-state battery is placed on top of the support plate 4 during assembly and pressurization. The second lifting component includes a screw 6 threaded on the support frame 2. The bottom end of the screw 6 is rotatably mounted on the pressure plate 7 through a bearing. Rotating the screw 6 can control the lifting of the pressure plate 7. The pressure display component includes a detection end 9 and a display end 8. The detection end 9 detects the pressure value and transmits the data to the display end 8 through a line or wireless communication. The display end 8 analyzes the data and displays it in real time. The detection end 9 includes at least one pressure sensor. The pressure sensor detects the received pressure value. The detection end 9 is flat and embedded in the groove on the top of the support plate 4. Its top height is lower than the edge height of the groove. Therefore, the detection end 9 can rise and fall with the support plate 4. In use, the solid-state battery is placed in the groove at the top of the support plate 4. The stainless steel frame of the solid-state battery presses against the top of the detection end 9. When the solid-state battery to be assembled is an electrolyte material that does not require high pressure, such as a composite solid-state electrolyte or a polymer electrolyte, the screw 6 above can be rotated to lower the pressure plate 7, fixing the solid-state battery in the support plate 4. Low pressure is then applied to the solid-state battery. The detection end 9 detects the pressure value in real time and displays it on the display end 8 for easy control of the battery pressure. When assembling solid-state batteries with oxide, sulfide, or halide electrolytes, the pressure can be continuously increased by the manual pump 5, raising the lifting cylinder 3 and the support plate 4, continuously increasing the pressure of the solid-state battery until the pressure value displayed on the display end 8 reaches a certain high pressure. In addition, during the assembly process, the pressure value can be increased or decreased in real time based on the real-time data detected by the detection end 9 to meet the battery assembly requirements. Furthermore, when it is necessary to move the device, the handle 16 can be rotated and then grasped to lift the entire device and transport it elsewhere, making it easier to transport and carry, and more convenient to use.

[0028] By setting up a support mechanism and a pressurizing mechanism including a first lifting component, a second lifting component and a pressure display component, the pressure requirements for assembling various electrolyte batteries can be met, and the battery pressure value can be displayed in real time, which is convenient for controlling the assembly quality of the battery. The overall structure of the device is simple and compact, making it easier to carry and transport.

[0029] Example 2:

[0030] like Figure 3 As shown, a support plate 17 is fixedly installed on the top of the lifting cylinder 3. The support plate 17 is magnetically attracted to the bottom of the support plate 4 by magnets or fixed by screws, thereby connecting the support plate 4 to the lifting cylinder 3. Therefore, the support plate 4 is more stable when the lifting cylinder 3 is raised or lowered.

[0031] By installing a support plate 17 on the top of the lifting cylinder 3, the lifting stability of the support plate 4 can be improved.

[0032] Example 3:

[0033] like Figure 2 and Figure 5 As shown, support rods 10 are fixedly installed on both sides of the support plate 4. The support frame 2 has a vertically opened guide slot 11. The support rods 10 pass through the guide slot 11 and the side of the support rods 10 slides in contact with the guide slot 11. A limiting plate 12 is installed on the support rods 10. The limiting plate 12 is located outside the guide slot 11 and slides in contact with the support frame 2. When the support plate 4 is raised or lowered, the support rods 10 rise or fall along the guide slot 11, thereby making the support plate 4 more stable.

[0034] By setting the support rod 10, guide slot 11 and limiting plate 12, the support plate 4 can be easily limited, making its lifting and lowering more stable.

[0035] Example 4:

[0036] like Figure 6 As shown, a signal line 14 is installed on one side of the detection end 9, and the other end of the signal line 14 is plugged into the display end 8. Furthermore, the signal line 14 includes a spiral section 15, allowing it to extend or retract according to the distance between the display end 8 and the detection end 9 (the spiral section 15 is extendable), preventing the wires from becoming tangled. Even further, a wire-holding groove 13 is formed at the top of the support rod 10, and a portion of the signal line 14 is embedded in the groove 13, preventing the exposed signal line 14 from rubbing against the guide seam 11 and causing unnecessary wear, thus extending the service life of the signal line 14.

[0037] By setting up signal line 14 and guide slot 13, it is possible to easily connect detection end 9 and display end 8, while also helping to extend the service life of signal line 14.

[0038] Working Principle: During use, the solid-state battery is placed in the groove at the top of the support plate 4. The stainless steel frame of the solid-state battery presses against the top of the detection end 9. When the solid-state battery to be assembled is an electrolyte material that does not require high pressure, such as a composite solid-state electrolyte or polymer electrolyte, the screw 6 above can be rotated to lower the pressure plate 7, fixing the solid-state battery in the support plate 4. Low pressure is then applied to the solid-state battery. The detection end 9 detects the pressure value in real time and displays it on the display end 8, facilitating pressure control. When assembling oxide, sulfide, or halide electrolyte solid-state batteries, the lifting cylinder 3 can be continuously pressurized by the manual pump 5, causing it to rise and thus the support plate 4, continuously increasing the pressure of the solid-state battery until the pressure value displayed on the display end 8 reaches the high pressure required for assembly. Furthermore, during the assembly process, the pressure value can be adjusted in real time based on the data detected by the detection end 9 to meet battery assembly requirements. When the device needs to be moved, the handle 16 can be rotated and grasped to lift the entire device for transport, making it easier to carry and use.
