[0055] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] In the description of the present invention, it is to be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally disposed component. When a component is considered to be "disposed on" another component, it may be directly disposed on the other component or there may be a centrally disposed component.

[0057] In addition, terms such as "long", "short", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0058] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0059] See also Figures 1 to 9 , this embodiment provides a snap-on battery testing device for testing a battery 1. The battery 1 includes a battery cell 101, a flexible circuit board 102 electrically connected to the battery cell 101 at one end, and a terminal 103 electrically connected to the other end of the flexible circuit board 102. The size of the flexible circuit board 102 is slightly larger than the size of the terminal 103, so after the terminal 103 is fixed in the middle position of the end of the flexible circuit board 102, the edge position 1021 of the flexible circuit board 102 is exposed for clamping and fixing. Optionally, a carrier 7 is provided, and the battery cell 101 is fixed in the carrier 7. A through groove is provided on the side of the carrier 7, and the flexible circuit board 102 extends to the outside through the through groove to connect with the terminal 103.

[0060] The button-fit battery testing device comprises a positioning mechanism, a first clamping mechanism 3, a second clamping mechanism 4, a testing assembly 5 and a driving mechanism.

[0061] The positioning mechanism is used to fix the battery cell 101. The positioning mechanism includes a first linear drive mechanism 201 and a second linear drive mechanism 202. The driving directions of the first linear drive mechanism 201 and the second linear drive mechanism 202 are perpendicular to each other. For example, when the first linear drive mechanism 201 is extended, the carrier 7 is pressed from the X-axis direction (front-back direction), and when the second linear drive mechanism 202 is extended, the carrier 7 is pressed from the Y-axis direction (left-right direction), thereby fixing the battery cell 101.

[0062] The linear drive mechanisms described in this embodiment may be a telescopic cylinder, a rodless cylinder, a hydraulic cylinder, or a motor screw assembly, etc. The specific structure of each linear drive mechanism is not the focus of this embodiment, so it will not be described in detail.

[0063] The first clamping mechanism 3 is used to clamp and fix the end of the flexible circuit board 102 away from the battery cell 101. It is understandable that the flexible circuit board 102 is easy to deform, so it is difficult to directly fix the terminal 103. In this embodiment, the first clamping mechanism 3 is provided to first clamp and fix the end of the flexible circuit board 102 close to the terminal 103 to achieve rough positioning of the terminal 103, and then use the second clamping mechanism 4 in the subsequent steps to achieve fine positioning of the terminal 103.

[0064] Optionally, the first clamping mechanism 3 includes a first clamping jaw 301, a first front clamping plate 302 and a first rear clamping plate 303. The lower portion of the first front clamping plate 302 is fixedly connected to one clamping arm of the first clamping jaw 301. The lower portion of the first rear clamping plate 303 is fixedly connected to the other clamping arm of the first clamping jaw 301. When the first clamping jaw 301 is closed, the first front clamping plate 302 and the first rear clamping plate 303 can clamp the flexible circuit board 102 from the X-axis direction.

[0065] The second clamping mechanism 4 is used to fix the flexible circuit board 102 around the connecting terminal 103 on the first clamping mechanism 3, so that the connecting terminal 103 is relatively fixed to the first clamping mechanism 3. The second clamping mechanism 4 includes a second clamping jaw 401, a second upper clamping plate 402 and a second lower clamping plate 403. The second clamping jaw 401 is fixed on the first rear clamping plate 303. One end of the second upper clamping plate 402 is fixedly connected to one clamping arm of the second clamping jaw 401. One end of the second lower clamping plate 403 is fixedly connected to the other clamping arm of the second clamping jaw 401.

[0066] A clamping boss 3031 for holding the flexible circuit board 102 is provided in the middle of the first rear clamping plate 303. The clamping boss 3031 is located between the second upper clamping plate 402 and the second lower clamping plate 403, and a stopper 304 is provided on both the upper and lower surfaces of the clamping boss 3031. The surfaces of the second upper clamping plate 402 and the second lower clamping plate 403 close to the corresponding stopper 304 are both provided with a clearance groove, and a rotating clamp block 404 is provided in the clearance groove, and the rotating clamp block 404 is rotatably connected to the clearance groove through a horizontal rotating shaft 405. The first end of the rotating clamp 404 is opposite to the stop top 304, and the second end is opposite to the clamping boss 3031 for abutting the surface of the flexible circuit board 102; when the rotating clamp 404 approaches the clamping boss 3031, the stop top 304 abuts against the first end of the rotating clamp 404, so that the second end of the rotating clamp 404 rotates forward around the horizontal rotation axis 405 to cooperate with the clamping boss 3031 to clamp the edge position 1021 of the flexible circuit board 102 around the terminal block 103, thereby achieving precise positioning of the terminal block 103.

[0067] A compression spring 406 is further provided on the side of the first end of the rotating clamp block 404 away from the stop top portion 304. When the second upper clamp plate 402 and the second lower clamp plate 403 are separated from each other, the stop top portion 304 is separated from the first end of the rotating clamp block 404, and the compression spring 406 drives the rotating clamp block 404 to rotate in the opposite direction, and the second end of the rotating clamp block 404 is away from the clamping boss 3031, thereby releasing the flexible circuit board 102 around the connection terminal 103.

[0068] The test assembly 5 is used for plugging with the wiring terminal 103 , and includes a test interface 501 , a mounting plate assembly 502 , an angle adjustment motor and a buffer spring 503 .

[0069] The test interface 501 is used for plugging with the wiring terminal 103. The test interface 501 is fixedly arranged on a side of the mounting plate assembly 502 close to the wiring terminal 103. The driving shaft of the angle adjustment motor is fixedly connected to the mounting plate assembly 502, and is used to rotate the mounting plate assembly 502 before plugging, so that the test interface 501 rotates to align with the wiring terminal 103. A buffer spring 503 is provided on the side of the mounting plate assembly 502 away from the wiring terminal 103, so as to provide buffering when the test interface 501 is docked with the wiring terminal 103, so as to avoid damage to the test interface 501 and the wiring terminal 103.

[0070] Optionally, the camera 8 may be configured to acquire and analyze the graphic information of the connection terminal 103 , and then adjust the angle of the test interface 501 according to the analysis result.

[0071] The driving assembly 6 is connected to the test assembly 5, and is used to drive the test assembly 5 to be plugged into the wiring terminal 103. Optionally, the driving assembly 6 includes a third clamping mechanism 601 and a third linear driving mechanism 602. The third clamping mechanism 601 is used to clamp the mounting plate assembly 502. The third linear driving mechanism 602 is used to drive the third clamping mechanism 601 to approach or move away from the wiring terminal 103.

[0072] In this embodiment, each clamping jaw can be a mechanical mechanism such as a clamping jaw cylinder or a clamping jaw hydraulic cylinder that can realize clamping and releasing operations.

[0073] Specifically, the button-type battery testing device provided in this embodiment has the following working process:

[0074] ① Open the cover of the carrier 7, put the battery cell 101 of the battery 1 into the carrier 7, expose the flexible circuit board 102 through the through groove, and rotate the cover of the carrier 7;

[0075] ② Use a robot or other equipment to place the carrier 7 on the positioning mechanism. At this time, the exposed end of the flexible circuit board 102 is just located between the first front clamping plate 302 and the first rear clamping plate 303;

[0076] ③ The first linear drive mechanism 201 and the second linear drive mechanism 202 extend in sequence to fix the carrier 7;

[0077] ④ The first clamping jaw 301 is closed to clamp the exposed end of the flexible circuit board 102;

[0078] ⑤ The second clamping jaw 401 is closed to clamp the flexible circuit board 102 around the connecting terminal 103, so that the connecting terminal 103 is completely fixed;

[0079] ⑥ The third clamping mechanism 601 is released, and the angle adjustment motor rotates so that the test interface 501 is aligned with the connection terminal 103;

[0080] ⑦ The third clamping mechanism 601 clamps the mounting plate assembly 502, and the third linear drive mechanism 602 drives the mounting plate assembly 502 to drive the test interface 501 to approach the wiring terminal 103, so as to achieve the plugging of the test interface 501 and the wiring terminal 103 for subsequent testing operations.

[0081] The snap-on battery testing equipment provided in this embodiment is respectively provided with a first clamping mechanism and a second clamping mechanism to clamp the flexible circuit board twice in succession.
