Description

Technical Field

[0001] The present application relates to the field of detection technology, and in particular to a solid-state battery power-on detection device and a performance detection system. Background Art

[0002] Solid-state batteries are a type of battery technology that uses solid electrolytes instead of traditional liquid electrolytes. Compared with traditional lithium-ion batteries, they have inherently higher safety, energy density, and cycle life, and are widely used in new energy vehicles, aerospace, consumer electronics, smart wearables, and other fields.

[0003] After the solid-state battery is produced, it is necessary to conduct a power-on test on the solid-state battery and record the current and voltage parameters of the solid-state battery. The solid-state battery has a positive and negative pole. After the power-on test of the solid-state battery is completed, the battery capacity test, cycle life test, overcharge and over-discharge test, short circuit test, etc. are also required.

[0004] When conducting power-on testing on solid-state batteries in relevant documents, a multimeter is usually used for testing. After the test, it cannot guarantee that the positive and negative poles of the front and rear solid-state batteries remain in the same orientation, which affects the measurement of the next process. Therefore, it is usually necessary to adjust the orientation of the solid-state battery after the power-on test is completed, which is cumbersome.

[0005] In view of this, there is an urgent need to provide a detection device that can automatically adjust and unify the orientation of the solid-state battery during the detection process, thereby simplifying the operational complexity of subsequent detection processes. Summary of the invention

[0012] Among them, when the positive and negative poles of the solid-state battery are connected to the detection structure through the first detection part and the second detection part respectively, a current loop is formed in the detection structure, and a magnetic force is generated between the first magnet and the second magnet, driving the steering wheel to rotate to the predetermined position to unload the material.

[0013] Furthermore, a tray is fixedly provided on the base, the steering wheel is rotatably provided on the tray, a movable part is vertically provided on the tray, and an arc-shaped groove communicating with the detection hole is provided on the steering wheel;

[0015] Among them, when the steering disk rotates to a predetermined position, the detection hole overlaps with the discharge trough, and at the same time the movable part extends into the arc groove, pushing the first detection part or the second detection part to disengage from the solid-state battery to be tested, and the solid-state battery to be tested disengages from the detected structure and enters the discharge trough.

[0016] Furthermore, the first detection unit and the second detection unit are both provided with a recovery structure, and the recovery structure includes:

[0017] A return pipe, one end of which is connected to the first detection part or the second detection part, and the other end of which is slidably connected to the steering plate;

[0018] An elastic member is inserted into the return tube, one end of which abuts against the steering wheel and the other end abuts against the return tube, and is used to drive the corresponding first detection part or the second detection part to reset.

[0019] Furthermore, a ball is rotatably provided on the end of the movable part, and the movable part pushes the first detection part or the second detection part to move linearly and separate from the solid-state battery under test.

[0020] Furthermore, the bottom sides of the first detection part and the second detection part are provided with tooth grooves, and the first detection part and the second detection part are both provided with a stop structure for supporting the solid-state battery to be tested; the two groups of the stop structures are connected by gear transmission, and the stop structure includes:

[0022] A movable wheel, fixed to the threaded rod and meshing with the tooth groove;

[0023] The stop plate is telescopically arranged in the detection hole and is threadably connected to the threaded rod.

When the solid-state battery is placed in the detection hole, the detection structure detects the performance parameters of the solid-state battery. During the detection process, the first magnet is energized, and an interaction force is generated between the first magnet and the second magnet.

DETAILED DESCRIPTION

[0038] The following will be combined with the attached Figure 1-4 The technical solution of the present application is described clearly and completely. The following embodiments are exemplary and are only used to explain the present application, and cannot be interpreted as limiting the present application. In the following description, the same symbols are used to represent the same or equivalent elements, and repeated descriptions are omitted.

[0039] In the description of the present application, it should be understood that the terms "upper", "lower", "inside", "outside", "left", "right", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the products of the present application are conventionally placed when in use, or are the orientations or positional relationships conventionally understood by those skilled in the art. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0040] In addition, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] It should be further understood that the term “and / or” used in the specification and corresponding claims of this application refers to any and all possible combinations of one or more of the listed items.

[0042] A solid-state battery power-on detection device, referring to Figure 1 and Figure 2 , including a base 1, a tray 4 and a steering structure 2; wherein the tray 4 is fixed to the base 1, the steering structure 2 is arranged on the tray 4, the steering structure 2 includes a steering disk 21, a first magnet 22 and a second magnet 23, the steering disk 21 is rotatably connected to the tray 4, the first magnet 22 is fixed on the steering disk 21, and the second magnet 23 is fixed on the base 1.

[0043] Further, refer to Figure 1 The steering plate 21 is provided with a detection hole 211, and a detection structure 3 is disposed in the detection hole 211. The first magnet 22 is electrically connected to the detection structure 3, and specifically, the detection structure 3 includes a first detection portion 31 and a second detection portion 32, and the first detection portion 31 and the second detection portion 32 are disposed opposite to each other.

[0044] When the solid-state battery is placed in the detection hole 211, the detection structure 3 detects the current and voltage of the solid-state battery. Correspondingly, the detection structure 3 also includes a multimeter 9, which is set on the steering wheel 21 and is used to record the current and voltage of the solid-state battery to be tested.

[0045] When the positive and negative electrodes of the solid-state battery are connected to the detection structure 3 through the first detection part 31 and the second detection part 32 respectively, a current loop is formed in the detection structure 3, the first magnet 22 is activated, and a magnetic force is generated between the first magnet 22 and the second magnet 23, thereby driving the steering disk 21 to rotate to the predetermined unloading position.

[0046] Specifically, when the positive pole of the solid-state battery is connected to the first detection part 31, the steering disc 21 rotates forward, and when the negative pole of the solid-state battery is connected to the first detection part 31, the steering disc 21 rotates reversely. That is, the detection structure 3 can be adaptively rotated according to the orientation of the positive and negative poles of the solid-state battery, so that after the solid-state battery is detected, the orientation of the front and rear tested solid-state batteries is always consistent, so as to facilitate other subsequent detection work.

[0047] It should be noted that the second magnet 23 can be a permanent magnet or an electromagnet. The present application does not make any specific settings for the specific form of the second magnet 23, and it is sufficient to ensure that magnetic force can be generated when the first magnet 22 is activated.

[0048] Furthermore, the solid-state battery is transported to the detection hole 211 by a manipulator (not shown). When the solid-state battery fails and cannot supply power, the steering disc 21 does not rotate. Correspondingly, a displacement sensor can be provided on the steering disc 21. When no displacement occurs, the displacement sensor transmits a signal to enable another manipulator to take the faulty solid-state battery out of the detection hole 211.

[0049] Correspondingly, refer to Figure 1 and Figure 2 A material discharge chute 41 is provided in the center of the tray 4, a movable portion 5 is vertically provided on the tray 4, and an arc groove 212 connected to the detection hole 211 is provided on the steering plate 21; the movable portion 5 is inserted into the arc groove 212, and the first detection portion 31 and the second detection portion 32 can be reset in the detection hole 211.

[0050] The initial position of the steering wheel 21 is taken as the starting point, and the final stop position of the steering wheel 21 rotating forward or reverse is taken as the end point;

[0051] In a specific embodiment, when the steering disk 21 is at the starting point (initial position), the detection hole 211 and the material discharge trough 41 are staggered, and the solid-state battery can be stably placed in the detection hole 211. At the end point (predetermined position), the detection hole 211 and the material discharge trough 41 overlap.

[0052] During the rotation of the steering disk 21, the movable part 5 at this time slides in the arc groove 212 and finally extends into the monitoring hole, pushing the first detection part 31 or the second detection part 32 to move (specifically, the first detection part 31 is pushed when the steering disk 21 rotates forward, and the second detection part 32 is pushed when the steering disk 21 rotates reversely), so that the first detection part 31 or the second detection part 32 is disengaged from the solid-state battery, and one end of the solid-state battery loses the restraint force and enters into the discharge chute 41 from the detection hole 211.

[0053] Furthermore, in another specific embodiment, when the steering disk 21 is at the starting point, the detection hole 211 and the material discharge chute 41 may also be arranged to overlap.

[0054] Combination Figure 3 The bottom sides of the first detection part 31 and the second detection part 32 are both provided with tooth grooves 33, the first detection part 31 and the second detection part 32 are both provided with stop structures 8, and the steering plate 21 is provided with stop grooves for accommodating the stop structures 8, and the two sets of stop structures 8 are connected by gear transmission.

[0055] When the steering wheel 21 is at the starting position, the stop structure 8 can support the solid-state battery. When the steering wheel 21 is at the end position, the first detection part 31 or the second detection part 32 is pushed, and the two stop structures 8 are synchronously retracted into the stop groove and no longer support the solid-state battery.

[0056] Specifically, the stop structure 8 includes a threaded rod 81, a movable wheel 82 and a stop plate 83. The movable wheel 82 is fixed to the threaded rod 81 and is coaxially arranged with the threaded rod 81. The movable wheel 82 is engaged with the tooth groove 33. The stop plate 83 is slidably arranged in the stop groove and is threadedly connected to the threaded rod 81 to perform telescopic movement in the detection hole 211.

[0057] When the movable part 5 pushes the first detection part 31 or the second detection part 32, the first detection part 31 or the second detection part 32 performs linear motion. Since the tooth groove 33 is engaged with the movable wheel 82, the threaded rod 81 is driven to rotate. The threaded rod 81 further drives the stop plate 83 to slide and retract into the stop groove. At this time, the solid-state battery smoothly enters the discharge chute 41.

[0058] By providing the stop structure 8, when the steering wheel 21 is in the initial position, any relative position state between the detection hole 211 and the discharge chute 41 can achieve a good fixing effect on the solid-state battery, making the installation of the steering wheel 21 more flexible.

[0059] Correspondingly, refer to Figure 1 A ball 7 is rotatably provided on the end of the movable part 5, and the movable part 5 pushes the first detection part 31 or the second detection part 32 to move linearly.

[0060] The movable part 5 makes a circular motion relative to the first detection part 31 or the second detection part 32, while the first detection part 31 or the second detection part 32 needs to make a linear motion in order to drive the stop structure 8 to operate. The setting of the ball 7 can reduce the friction between the movable part 5 and the first detection part 31 and the second detection part 32, so that the end of the movable part 5 can slide on the corresponding first detection part 31 or the second detection part 32.

[0061] Further, refer to Figure 3 and Figure 4 The first detection part 31 and the second detection part 32 are both provided with a restoring structure 6 , and the first detection part 31 and the second detection part 32 can be reset in the detection hole 211 through the corresponding restoring structure 6 .

[0062] Specifically, the return structure 6 includes a return tube 61 and an elastic member 62. A return hole is opened on the steering plate 21. One end of the return tube 61 is inserted into the return hole and slides in the return hole. The other end of the return tube 61 is fixedly connected to the corresponding first detection part 31 or the second detection part 32. The elastic member 62 is arranged in the return tube 61, one end of which is against the bottom wall of the return hole, and the other end is against the return tube 61.

[0063] The setting of the return tube 61 can provide a position for the installation of the elastic member 62, and provide a guide for the movement of the first detection part 31 and the second detection part 32, so as to ensure that the first detection part 31 and the second detection part 32 can move smoothly. When the corresponding first detection part 31 or the second detection part 32 is pushed by the movable part 5, the elastic member 62 will shrink. When the corresponding first detection part 31 or the second detection part 32 is no longer in contact with the movable part 5, the elastic member 62 rebounds to reset the corresponding first detection part 31 or the second detection part 32, so as to facilitate the detection of the next solid-state battery.

[0064] Further, refer to Figure 2 A spiral spring 10 is arranged between the tray 4 and the steering plate 21 , one end of the spiral spring 10 is connected to the tray 4 , and the other end of the spiral spring 10 is connected to the steering plate 21 .

[0065] By setting the spiral spring 10, when the solid-state battery enters the discharge chute 41 and no longer supplies power to the first magnet 22, there is no interaction force between the first magnet 22 and the second magnet 23, and the spiral spring 10 rebounds to reset the steering disk 21, further facilitating the detection of the next solid-state battery.

[0066] It should be noted that the time required for the solid-state battery to be detected is less than the time required for the steering wheel 21 to rotate from the starting point to the end point, so as to ensure the stable operation of the detection work.

[0067] Further, refer to Figure 2 and Figure 3 The tray 4 is provided with an ejection hole 42 connected to the feed chute 41, and an ejection structure 20 extends into the ejection hole 42. When the solid-state battery enters the feed chute 41, the ejection structure 20 pushes the solid-state battery to be moved out of the ejection hole 42, so that the solid-state battery being tested can be output to the next unit in a consistent direction.

[0068] Further, refer to Figure 2 A flexible protective layer 30 is provided on the bottom wall of the feed chute 41, wherein the flexible protective layer 30 can be specifically provided according to the actual situation, such as a sponge pad, a silicone pad, etc. In the process of fixing the battery into the feed chute 41, the flexible protective layer 30 can better support the solid-state battery, thereby protecting the solid-state battery and reducing the possibility of damage to the solid-state battery after the inspection is completed.

[0069] In addition, the present application also discloses a solid-state battery performance detection system, which performs at least power-on detection, battery capacity detection, cycle life detection, overcharge and overdischarge detection, and short circuit detection on the solid-state battery. The performance detection system includes the above-mentioned power-on detection device, which is used to perform power-on detection on the solid-state battery.

[0070] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
