Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a solid-state battery testing device, including a U-shaped frame 1, a placement plate 2 placed inside the U-shaped frame 1, nine placement slots 3 opened on the top of the placement plate 2, nine detectors 4 installed on the top of the U-shaped frame 1, each detector 4 corresponding to a placement slot 3, the positive terminal of the detector 4 connected to a positive probe 7 via a wire, the negative terminal of the detector 4 connected to a negative probe 8 via a wire through the U-shaped frame 1, an insertion assembly 9 installed on the U-shaped frame 1, the movable end of the insertion assembly 9 fixedly connected to the positive probe 7 and the negative probe 8, and a through hole 5 opened on the placement plate 2. Connected to the placement slot 3, the positive electrode probe 7 and the negative electrode probe 8 extend into the through hole 5. The nine placement slots 3 and nine detectors 4 can simultaneously detect nine solid-state batteries, improving the detection efficiency for large batches of solid-state batteries. The positive electrode probe 7 and the negative electrode probe 8 are connected and removed by the insertion component 9. Since solid-state batteries generally do not contain electrolyte or contain only a small amount of electrolyte, and the batteries are relatively rigid and not easily deformed, when the ends of the positive electrode probe 7 and the negative electrode probe 8 are directly pressed against the positive and negative terminals of the fixed battery for conductive connection, a good conductive connection effect can also be ensured.

[0020] The placement slot 3 has a shape that is larger at the top and smaller at the bottom. The top edge of the placement slot 3 has a thumb groove, which makes it convenient for workers to place and take out the solid-state battery in the placement slot 3.

[0021] An elastic snap-fit ​​piece 10 is fixedly installed on the inner wall of the placement slot 3. An avoidance groove 1001 is provided on the elastic snap-fit ​​piece 10. The inner diameter of the avoidance groove 1001 is larger than the outer diameter of the positive probe 7 and the negative probe 8. The elastic snap-fit ​​piece 10 is used to hold the two ends of the fixed battery, which plays a certain role in snapping the solid battery and preventing the solid battery from falling out of the placement slot 3 during the testing process.

[0022] The insertion assembly 9 has two sets, one connected to the positive probe 7 and the other connected to the negative probe 8. The insertion assembly 9 includes a guide rail 902, which is fixedly installed on the inner top wall of the U-shaped frame 1. A servo motor 901 is fixedly installed at one end of the guide rail 902, and a lead screw 904 is fixedly installed at the output end of the servo motor 901. A sliding plate 903 is threaded onto the outer wall of the lead screw 904, and the sliding plate 903 slides within the guide rail 902. A connecting rod 905 is fixedly installed at the bottom of the sliding plate 903, and a mounting bracket 906 is fixedly installed at the bottom end of the connecting rod 905. One set of insertion assembly 9... The mounting bracket 906 is fixedly connected to nine positive probes 7, and another set of mounting brackets 906 inserted into the component 9 is fixedly connected to nine negative probes 8. The servo motor 901 drives the lead screw 904 to rotate, which in turn causes the slide plate 903 to move in the guide rail 902. The movement of the slide plate 903 causes the connecting rod 905 to move, which in turn causes the mounting bracket 906 to move, so that the positive probes 7 and negative probes 8 installed on the mounting bracket 906 can move to attach the ends of the positive probes 7 and negative probes 8 to the positive and negative terminals of the solid-state battery, and to pull the positive probes 7 and negative probes 8 out of the through hole 5.

[0023] A cross-shaped rubber plug 6 is fixedly installed on the inner wall of the through hole 5. When the positive probe 7 and the negative probe 8 pass through the cross-shaped rubber plug 6, the dust on them will be scraped off by the cross-shaped rubber plug 6 to avoid a large amount of dust remaining on the positive probe 7 and the negative probe 8, which would affect the detection.

[0024] The bottom of the placement plate 2 is provided with a sloping slot 11, and the bottom inner wall of the U-shaped frame 1 is fixedly installed with a sloping block 12. The sloping block 12 is inserted into the sloping slot 11. The sloping slot 11 and the sloping block 12 are set to position and limit the placement plate 2 placed in the U-shaped frame 1, so as to prevent the position of the placement plate 2 from changing during the testing process.

[0025] Working principle: In use, nine solid-state batteries are placed into nine placement slots 3, and placement plate 2 is placed into U-shaped frame 1. When placing, the inclined slot 11 is aligned with the inclined block 12 before being lowered to lock placement plate 2. The servo motor 901 is turned on to drive the lead screw 904 to rotate, which in turn causes the slide plate 903 to move within the guide rail 902. The movement of slide plate 903 causes the connecting rod 905 to move, which in turn causes the mounting bracket 906 to move, which in turn causes the positive probe 7 and negative probe 8 mounted on the mounting bracket 906 to move, so that the ends of the positive probe 7 and negative probe 8 can be attached to the positive and negative terminals of the solid-state batteries. The detector 4 can then be turned on to test the solid-state batteries.

[0026] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
