Description

Technical Field

[0001] This utility model relates to the field of solid-state batteries, and in particular to a solid electrolyte pressurization device. Background Technology

[0002] The solid electrolyte is the most important core component of a solid-state battery, and the most important performance indicators for judging the quality of a solid electrolyte are ionic conductivity, lithium metal interface stability, and full-cell performance. Currently, when conducting various tests (i.e., testing procedures) on solid electrolytes, pressure must be applied.

[0003] The common method for pressurizing solid electrolytes is as follows: First, the solid electrolyte is placed in a test fixture (which has at least two pressure plates and multiple bolt assemblies connecting the two pressure plates). Then, a pressure-applying device (such as a jack) is used to apply pressure to the test fixture to the required pressure. Next, the operator manually tightens each bolt assembly of the test fixture to ensure stable pressure on the solid electrolyte. Finally, the pressure is released and the test fixture is removed. However, because the operator manually tightens each bolt assembly, uneven tightening can easily occur, causing the two pressure plates of the test fixture to be non-parallel. This results in uneven pressure on the solid electrolyte, affecting the test results.

[0004] In view of the above problems, it is necessary to study a solid electrolyte pressurization device that can make the solid electrolyte uniformly pressurized. Utility Model Content

[0005] The purpose of this invention is to provide a solid electrolyte pressurization device that enables the solid electrolyte to be uniformly pressurized.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A solid electrolyte pressurization device includes a frame, and a pressurization device, a locking device, and a control device that cooperate with the frame. The frame is provided with a pressure plate, which has a plurality of bolt assembly alignment holes. The pressurization device has a liftable pressurization seat located below the pressure plate. The locking device includes an electric tightening machine and a locking lifting device that drives the electric tightening machine to move up and down. The electric tightening machine is located above the pressure plate and has a plurality of rotatable tightening heads corresponding to the alignment holes of each bolt assembly. The control device is electrically connected to the pressurization device, the electric tightening machine, and the locking lifting device.

[0008] The tightening head includes a detachably connected tightening body and a tightening sleeve, with the tightening sleeve located below the tightening body.

[0009] The tightening body has a hollow sleeve portion, and the side wall of the sleeve portion has two elongated holes that are opposite to each other and arranged in the vertical direction; the tightening sleeve is inserted into the sleeve portion, and the tightening sleeve is fitted with a connecting pin, which passes through the two elongated holes of the sleeve portion.

[0010] The electric tightening machine has a tightening motor, which is connected to each tightening head for transmission. The tightening motor is equipped with a torque sensor, and the tightening motor and torque sensor are electrically connected to the control device.

[0011] The locking and lifting device includes a fixed base, a lead screw, a lead screw nut, a guide rail, a guide rail slider, and a drive motor. The fixed base and the drive motor are mounted on the frame. The lead screw is rotatably fitted to the fixed base and is arranged in the vertical direction. The lead screw nut is screwed to the lead screw and is fixedly connected to the electric tightening machine. The guide rail is fixedly fitted to the fixed base and is arranged in the vertical direction. The guide rail slider slides against the guide rail and is fixedly connected to the electric tightening machine. The drive motor is driven by the lead screw and is electrically connected to the control device.

[0012] The pressure seat is provided with an installation through groove, and limiting sliding grooves are formed on both sides of the installation through groove. A positioning block is provided in the installation through groove.

[0013] The frame is provided with multiple guide rods, and the pressure seat is slidably connected to each guide rod.

[0014] The pressurizing device also has a jack connected to the pressurizing base, the jack is equipped with a pressure sensor, and the jack and pressure sensor are electrically connected to the control device.

[0015] The control device has a touch screen display.

[0016] The pressure plate is equipped with a displacement sensor, which is electrically connected to the control device.

[0017] With the above solution, when using the solid electrolyte pressurizing device of this utility model, firstly, the test fixture containing the solid electrolyte is installed on the pressurizing base; then, the pressurizing device drives the pressurizing base to move upward, so that the test fixture is clamped between the pressurizing base and the pressure plate, so that each bolt assembly of the test fixture is inserted into the alignment hole of each bolt assembly, and at the same time, the pressurizing device continues to apply pressure to the test fixture; when the pressurizing device applies pressure to the test fixture to the command pressure, the locking lifting device drives the electric tightening machine to move downward until each tightening head is inserted into each bolt assembly of the test fixture; then, the electric tightening machine works so that each tightening head simultaneously tightens each bolt assembly of each test fixture synchronously, so that each bolt assembly of the test fixture is locked synchronously; then, the locking lifting device drives the electric tightening machine to move upward and reset; finally, the pressurizing device drives the pressurizing base to move downward and reset. In this invention, because an electric tightening machine is used to simultaneously tighten each bolt assembly of each test fixture, the tightening degree of each bolt assembly of the test fixture is the same, thereby ensuring that the two pressure plates of the test fixture are parallel to each other, so that the test fixture can apply pressure to the solid electrolyte evenly, thus ensuring that the solid electrolyte is evenly pressurized.

[0042] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0043] like Figures 1 to 5 As shown, this utility model discloses a solid electrolyte pressurization device A, which includes a frame 1, a pressurization device 2, a locking device 3, and a control device 4 that are coupled to the frame 1. The frame 1 has a pressure plate 11 with multiple bolt assembly alignment holes 111. The pressurization device 2 has a liftable pressurization seat 21 located below the pressure plate 11. The locking device 3 includes an electric tightening machine 31 and a locking lifting device 32 that drives the electric tightening machine 31 to move up and down. The electric tightening machine 31 is located above the pressure plate 11 and has multiple rotatable tightening heads 311 corresponding to the alignment holes 111 of each bolt assembly. The control device 4 is electrically connected to the pressurization device 2, the electric tightening machine 31, and the locking lifting device 32.

[0044] Cooperate Figures 1 to 6 As shown, when using the solid electrolyte pressurizing device A of this utility model, firstly, the test fixture B containing the solid electrolyte is installed on the pressurizing base 21; then, the pressurizing device 2 drives the pressurizing base 21 to move upward, so that the test fixture B is clamped between the pressurizing base 21 and the pressure plate 11, so that each bolt B21 assembly B2 of the test fixture B is inserted into the alignment hole 111 of each bolt assembly, and at the same time, the pressurizing device 2 continues to apply pressure to the test fixture B; when the pressurizing device 2 applies pressure to the test fixture B to the command pressure, it is locked. The lifting device 32 drives the electric tightening machine 31 to move down until each tightening head 311 is inserted into each bolt B21 assembly B2 of the test fixture B. Then, the electric tightening machine 31 works so that each tightening head 311 simultaneously tightens each bolt B21 assembly B2 of each test fixture B, so that each bolt B21 assembly B2 of the test fixture B is locked synchronously. Next, the locking lifting device 32 drives the electric tightening machine 31 to move up and reset. Finally, the pressurizing device 2 drives the pressurizing seat 21 to move down and reset. In this invention, because the electric tightening machine 31 simultaneously tightens each bolt B21 assembly B2 of each test fixture B, the tightening degree of each bolt B21 assembly B2 of the test fixture B is guaranteed to be the same, thereby ensuring that the two pressure plates B1 of the test fixture B are parallel to each other, so that the test fixture B can apply pressure evenly to the solid electrolyte, thus ensuring that the solid electrolyte is evenly pressurized; and the user can control the operation of the pressure device 2 and the locking device 3 through the control device 4, as well as control the pressure applied by the pressure device 2 to the test fixture B and control the torque of the electric tightening machine 31 when tightening the bolt B21 assembly B2.

[0045] In an embodiment of this utility model, the control device 4 may have a touch screen display 41, through which the user inputs commands to control whether the pressurizing device 2 and the locking device 3 are working, as well as to control the pressure applied by the pressurizing device 2 to the test fixture B and the torque of the electric tightening machine 31 when tightening the bolt B21 assembly B2. The control device 4 may be equipped with a PLC controller or a microcontroller, which controls the pressurizing device 2 and the locking device 3.

[0046] In an embodiment of this utility model, the electric tightening machine 31 includes a tightening motor 312, which is driven by each tightening head 311. The tightening motor 312 is equipped with a torque sensor (not shown), and the tightening motor 312 and the torque sensor are electrically connected to the control device 4. The control device 4 detects the tightening torque of the electric tightening machine 31 on the bolt B21 assembly B2 through the torque sensor. When the tightening torque of the electric tightening machine 31 on the bolt B21 assembly B2 reaches a set value, the control device 4 controls the tightening motor 312 to stop working. The tightening motor 312 can be driven by each tightening head 311 through a gear transmission mechanism 313, which has the advantage of high transmission efficiency. The tightening motor 312, the gear transmission mechanism 313, and each tightening head 311 can be mounted on a tightening base 314, which is connected to the locking lifting device 32. It should be noted that the tightening motor 312 can also be driven and cooperated with each tightening head 311 through other transmission mechanisms.

[0047] In an embodiment of this utility model, the tightening head 311 includes a detachably connected tightening body 3111 and a tightening sleeve 3112. The tightening body 3111 is driven by the tightening motor 312. The tightening sleeve 3112 is located below the tightening body 3111. The tightening sleeve 3112 is used to connect with the nut B22 or bolt B21 of the bolt B21 assembly B2. The user can select the appropriate tightening sleeve 3112 to connect with the tightening body 3111 according to the different specifications of the bolt B21 assembly B2. The tightening body 3111 has a hollow sleeve portion 31111, and the side wall of the sleeve portion 31111 has two elongated holes 31112 that are opposite to each other and arranged in the vertical direction. The tightening sleeve 3112 is inserted into the sleeve portion 31111, and the tightening sleeve 3112 is fitted with a connecting pin 3113, which passes through the two elongated holes 31112 of the sleeve portion 31111. This arrangement allows the tightening sleeve 3112 and the tightening body 3111 to be detachably connected and to be relatively movable, so that the tightening head 311 can be adapted to bolt B21 assembly B2 of different heights, ensuring that the tightening head 311 can be connected to the bolt B21 assembly B2.

[0048] In an embodiment of this utility model, the locking lifting device 32 may include a fixed base 321, a lead screw 322, a lead screw nut 323, a guide rail 324, a guide rail slider 325, and a drive motor 326; wherein, the fixed base 321 and the drive motor 326 are mounted on the frame 1, the lead screw 322 is rotatably fitted to the fixed base 321 and is arranged in the vertical direction, the lead screw nut 323 is screwed to the lead screw and is fixed to the electric tightening machine 31. The guide rail 324 is fixedly fitted to the fixed base 321 and is arranged vertically. The guide rail slider 325 slides with the guide rail 324 and is fixedly connected to the tightening base 314 of the electric tightening machine 31. The drive motor 326 is driven by the lead screw 322 and is electrically connected to the control device 4. The drive motor 326 drives the lead screw 322 to rotate, which causes the lead screw nut 323 to drive the electric tightening machine 31 to move up and down. The drive motor 326 can be driven by the lead screw through the synchronous belt transmission mechanism 327, which has the advantage of smooth transmission.

[0049] In an embodiment of this utility model, the pressurizing device 2 further includes a jack 22 connected to the pressurizing base 21. The jack 22 drives the pressurizing base 21 to move up and down and to apply pressure to the test fixture B. The jack 22 is equipped with a pressure sensor (not shown). The jack 22 and the pressure sensor are electrically connected to the control device 4. The control device 4 detects the pressure applied by the jack 22 to the test fixture B through the pressure sensor. When the jack 22 applies pressure to the test fixture B to the command pressure, the control device 4 controls the jack 22 to stop increasing the applied pressure.

[0050] In an embodiment of this utility model, the pressure seat 21 may be provided with a mounting groove 211 for mounting the test fixture B. Limiting sliding grooves 2111 are formed on both sides of the mounting groove 211 for sliding contact of a pressure plate B1 of the test fixture B. A positioning block 2112 is provided within the mounting groove 211 for limiting the position of the test fixture B. Furthermore, the frame 1 may be provided with multiple guide rods 12, and the pressure seat 21 slides with each guide rod 12 to ensure stable vertical movement of the pressure seat 21.

[0051] In an embodiment of this utility model, the pressure plate 11 of the frame 1 may be equipped with a displacement sensor (not shown). The displacement sensor is used to detect the relative displacement between the two pressure plates B1 of the test fixture B. The displacement sensor is electrically connected to the control device 4, which makes it convenient for the user to understand the relative displacement between the two pressure plates B1 of the test fixture B.

[0052] In an embodiment of this utility model, the solid electrolyte pressurizing device A may further include a chassis 5, which is connected to the frame 1. The chassis 5 covers and protects the pressurizing device 2 and the locking device 3. A touch screen 41 may be installed on the upper part of the chassis 5. The chassis 5 is provided with an operation port 51 corresponding to the pressure plate 11 and the pressure seat 21 for installing and removing the test fixture B. The test fixture B may be detachably fitted with a test jig C. The solid electrolyte is loaded into the test jig C. The test jig C may include a cylinder C1 with openings at both ends and two pressure heads C2 that are respectively inserted into the openings at both ends of the cylinder C1. The two pressure heads C2 are pressurized by the two pressure plates B1 of the test fixture B. The solid electrolyte is loaded into the cylinder C1 and is pressurized by the two pressure heads C2.
