Using a screwdriver to pry open the mold is not only time-consuming and laborious but also causes scratches and damage to the mold. Therefore, finding a convenient and quick way to open the mold without damaging it is a crucial issue for improving the efficiency of solid-state battery assembly. Utility Model Content

[0005] The beneficial effects of this invention are as follows: A solid-state battery mold is placed between the first and second structural components. A limiting device engages and limits the solid-state battery mold at a corresponding position, providing support. A hydraulic press applies pressure to one end of the solid-state battery mold, thereby opening the negative electrode side. This device quickly opens the negative electrode side by applying pressure to one end of the solid-state battery mold, avoiding scratches and damage to the mold. It is convenient, easy to operate, saves time and effort, and thus improves work efficiency.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the limiting device includes limiting plates, and the limiting plates are provided on the inner walls of the first structural member and the second structural member respectively. The limiting plates are perpendicular to the rotation axis of the first structural member and the second structural member, and the opposite ends of the two limiting plates are provided with grooves.

[0008] The beneficial effect of adopting the above-mentioned further solution is that by setting limiting plates on the inner walls of the first structural component and the second mechanical component, the limiting plates and the corresponding positions of the solid-state battery mold are engaged, and grooves are set at the opposite ends of the two limiting plates to avoid space, so that the solid-state battery mold is just engaged inside, thereby limiting and stabilizing the solid-state battery mold.

[0009] Furthermore, the groove is a semi-circular arc-shaped groove.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the semi-circular arc groove is compatible with the arc-shaped side wall surface of the solid-state battery, which can better limit the positioning of the solid-state battery mold.

[0011] Furthermore, the limiting device includes limiting plates, and a plurality of limiting plates are spaced apart on the inner walls of the first structural member and the second structural member respectively, and the limiting plates are perpendicular to the rotation axis of the first structural member and the second structural member.

[0012] The beneficial effect of adopting the above-mentioned further solution is that when the first structural component and the second structural component are closed, the solid-state battery mold is limited and supported at the corresponding positions by multiple limiting plates.

[0013] Furthermore, the limiting device is disposed in the middle of the inner wall of the first structural member and the second structural member.

[0014] The beneficial effect of adopting the above-mentioned further solution is that: the limiting device is set in the middle of the inner wall of the first structural member and the second structural member, which can correspond exactly to the corresponding position of the solid-state battery mold, thereby limiting its installation.

[0015] Furthermore, one end of the upper part of the first structural member extends outward to form a first protrusion 400, the other end of the upper part of the first structural member extends outward to form a second protrusion, one end of the lower part of the second structural member extends outward to form a third protrusion, one end of the lower part of the second structural member extends outward to form a fourth protrusion, the first protrusion and the third protrusion are rotatably connected, and the second protrusion and the fourth protrusion are detachably connected.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by cooperating with the first protrusion and the second protrusion of the first structural member with the third protrusion and the fourth protrusion of the second structural member, the connection between the first structural member and the second structural member is realized.

[0017] Furthermore, it also includes a screw, one end of which is threaded, the first protrusion is provided with a first through hole, the third protrusion is provided with a third through hole, the third through hole has an internal thread, and the screw passes through the first through hole and the third through hole and is threadedly connected to the internal thread.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by providing a first through hole on the first protrusion and a third through hole with internal thread on the second protrusion, the screw passes through the first through hole and the third through hole, thereby realizing the rotatable connection between one end of the first structural member and one end of the second structural member.

[0019] Furthermore, the device also includes a pin, the second protrusion having a second through hole, the fourth protrusion having a fourth through hole, one end of the pin passing through the second through hole and the fourth through hole, and being detachably connected to the second through hole and the fourth through hole.

[0020] The beneficial effect of adopting the above-mentioned further solution is that by providing a second through hole on the second protrusion and a fourth through hole on the fourth protrusion, the pin passes through the second through hole and the fourth through hole, thereby realizing the detachable connection between the other end of the first structural member and the other end of the second structural member.

[0021] Furthermore, the inner walls of the first structural member and the second structural member are arc-shaped surfaces.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the inner walls of the first and second structural components are set as arc-shaped surfaces to provide auxiliary support for the outer wall of the solid-state battery mold.

[0023] Furthermore, the diameter of the arc-shaped surface is greater than or equal to the outer diameter of the solid-state battery mold.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the diameter of the arc surface is set to be greater than or equal to the outer diameter of the solid-state battery mold, so that when the first structural component and the second structural component are closed, the solid-state battery mold can be locked between the first structural component and the second structural component.

[0030] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0031] like Figures 1-3 As shown, this embodiment provides an opening device for the negative electrode side of a solid-state battery mold, including a first structural member 100 and a second structural member 200. One end of the first structural member 100 and one end of the second structural member 200 are rotatably connected, and the other end of the first structural member 100 and the other end of the second structural member 200 are detachably connected. Limiting devices are provided on the inner sides of both the first structural member 100 and the second structural member 200.

[0032] In this embodiment, a solid-state battery mold is placed between the first structural member 100 and the second structural member 200. A limiting device is positioned at the corresponding location on the solid-state battery mold and engages to limit its movement while providing support. A hydraulic press applies pressure to one end of the solid-state battery mold, thereby opening the negative electrode side of the mold. This device quickly opens the negative electrode side by applying pressure to one end of the solid-state battery mold, avoiding scratches and damage to the mold. It is convenient to operate, saves time and effort, and thus improves work efficiency.

[0033] Based on any of the above solutions, the limiting device includes a limiting plate 310. The limiting plate 310 is provided on the inner walls of the first structural member 100 and the second structural member 200 respectively. The limiting plate 310 is perpendicular to the rotation axis of the first structural member 100 and the second structural member 200. The opposite ends of the two limiting plates 310 are provided with grooves.

[0034] By setting a limiting plate 310 on the inner wall of the first structural member 100 and the second structural member 200, the limiting plate 310 and the corresponding position of the solid-state battery mold are engaged. At the same time, the limiting plate 310 provides support during the demolding and pressurization process, so that the negative electrode side can be opened smoothly after demolding. Grooves are set at the opposite ends of the two limiting plates 310 to avoid space and just fit the solid-state battery mold in them, thereby limiting and stabilizing the solid-state battery mold.

[0035] Based on any of the above schemes, the groove is a semi-circular arc groove.

[0036] By setting the groove as a semi-circular arc groove, which matches the arc-shaped sidewall of the solid-state battery, the solid-state battery mold can be better positioned.

[0037] Based on any of the above solutions, the limiting device includes limiting pieces 320. Multiple limiting pieces 320 are spaced apart on the inner walls of the first structural member 100 and the second structural member 200, and the limiting pieces 320 are perpendicular to the rotation axes of the first structural member 100 and the second structural member 200.

[0038] When the first structural component 100 and the second structural component 200 are joined together, the solid-state battery mold is limited and supported at the corresponding positions by multiple limiting pieces 320.

[0039] Specifically, the opposing ends of the plurality of limiting pieces 320 are curved surfaces.

[0040] By setting the opposite ends of multiple limiting plates 320 to arc surfaces, they can better cooperate with the solid-state battery mold, thereby better limiting the position and providing support when the device is pressurized and demolded, thus smoothly opening the negative electrode side.

[0041] Based on any of the above solutions, the limiting device is disposed in the middle of the inner wall of the first structural member 100 and the second structural member 200.

[0042] The limiting device is set in the middle of the inner wall of the first structural member 100 and the second structural member 200, so that it can correspond to the corresponding position of the solid-state battery mold, thereby limiting its installation.

[0043] Based on any of the above solutions, one end of the upper part of the first structural member 100 extends outward to form a first protrusion 400, the other end of the upper part of the first structural member 100 extends outward to form a second protrusion 500, one end of the lower part of the second structural member 200 extends outward to form a third protrusion 600, one end of the lower part of the second structural member 200 extends outward to form a fourth protrusion 700, the first protrusion 400 is rotatably connected to the third protrusion 600, and the second protrusion 500 is detachably connected to the fourth protrusion 700.

[0044] The connection between the first structural member 100 and the second structural member 200 is achieved by engaging the first protrusion 400 and the second protrusion 500 of the first structural member 100 with the third protrusion 600 and the fourth protrusion 700 of the second structural member 200, respectively.

[0045] Based on any of the above solutions, a screw 800 is also included. One end of the screw 800 is provided with a thread. The first protrusion 400 is provided with a first through hole, and the third protrusion 600 is provided with a third through hole. The third through hole has an internal thread. The screw 800 passes through the first through hole and the third through hole and is threadedly connected to the internal thread.

[0046] By providing a first through hole on the first protrusion 400 and a third through hole with internal threads on the second protrusion 500, a screw 800 passes through the first through hole and the third through hole, thereby achieving a rotatable connection between one end of the first structural member 100 and one end of the second structural member 200.

[0047] Based on any of the above solutions, a pin 900 is also included. The second protrusion 500 is provided with a second through hole, and the fourth protrusion 700 is provided with a fourth through hole. One end of the pin 900 passes through the second through hole and the fourth through hole and is detachably connected to the second through hole and the fourth through hole.

[0048] By providing a second through hole on the second protrusion 500 and a fourth through hole on the fourth protrusion 700, and by having a pin 900 pass through the second through hole and the fourth through hole, the other end of the first structural member 100 and the other end of the second structural member 200 can be detachably connected.

[0049] Based on any of the above schemes, the inner walls of the first structural member 100 and the second structural member 200 are arc-shaped surfaces.

[0050] The inner walls of the first structural component 100 and the second structural component 200 are set as arc-shaped surfaces to provide auxiliary support for the outer wall of the solid-state battery mold.

[0051] Specifically, the outer walls of the first structural member 100 and the second structural member 200 can be curved surfaces or prismatic surfaces.

[0052] Alternatively, the inner walls of the first structural member 100 and the second structural member 200 can be prismatic surfaces.

[0053] In a specific example, the inner walls of the first structural member 100 and the second structural member 200 are prismatic surfaces. When the first structural member 100 and the second structural member 200 are closed, the inner walls of the first structural member 100 and the second structural member 200 form a prismatic shape.

[0054] Based on any of the above schemes, the diameter of the arc-shaped surface is greater than or equal to the outer diameter of the solid-state battery mold.

[0055] The diameter of the arc-shaped surface is set to be greater than the outer diameter of the solid-state battery mold. When the first structural component 100 and the second structural component 200 are closed, the solid-state battery mold can be engaged between the first structural component 100 and the second structural component 200.

[0056] In a specific example, the diameter of the curved surface is equal to the outer diameter of the solid-state battery mold. When the first structural member 100 and the second structural member 200 are closed, the solid-state battery mold fits perfectly against the inner walls of the first structural member 100 and the second structural member 200. The device with the battery mold installed and fixed is placed on a hydraulic press for pressure application, thereby making it more stable when the negative electrode side is opened.

[0057] In a specific example, the operation process of opening the fixed negative terminal side of the battery using this device is as follows: First, remove the pin 900, open the first structural component 100 and the second structural component 200, and place the negative terminal side of the solid-state battery mold, which has been difficult to open after long-cycle testing, into the mold. Then, close the first structural component 100 and the second structural component 200. The limiting plate 310 with grooves on the inner walls of the first structural component 100 and the second structural component 200 fits precisely in the corresponding position of the solid-state battery mold. Next, insert the pin 900 into the second and fourth through holes. At this point, the solid-state battery mold is installed. Then, place the device with the solid-state battery mold installed on a hydraulic press. The hydraulic press applies pressure from the positive terminal side to the negative terminal side, thereby removing the negative terminal side of the solid-state battery mold. By applying pressure to one end of the solid-state battery mold, the negative terminal side is quickly opened, avoiding scratches and damage to the mold. The entire process is convenient and easy to operate, saving time and effort, thus improving work efficiency.
