[0024] The present invention is further described in detail below in conjunction with the embodiments:
[0025] Example 1
[0026] like Figure 1As shown in FIG. 5 , the utility model provides a lithium battery production detection device, including a base 1, a fixing component 2, a collision component 3, and a buckle component 4. The base 1 includes a first baffle 101 and a second baffle 102. The collision component 3 includes a collision spring 301. The upper end of the collision spring 301 is fixedly connected to a connecting block 302. One end of the connecting block 302 is fixedly connected to an impact plate 303.

[0027] In this embodiment, the battery is fixed by the buckle assembly 4, and then the pull rod 307 is pulled to drive the top of the collision spring 301 to move toward the upper surface of the base 1, so that the collision spring 301 generates elastic force, and then the pull rod 307 is released so that the collision spring 301 drives the collision plate 303 to perform a reset movement, so that the collision plate 303 performs an impact test on the battery, thereby detecting the degree of impact resistance of the battery and facilitating the operation of the staff.
[0028] Example 2
[0029] like Figure 1 As shown in —5, on the basis of Example 1, the utility model provides a technical solution: preferably, the first baffle 101 and the second baffle 102 are fixedly connected to the two ends of the front end of the upper surface of the base 1, and a distance is provided between them for the connecting plate 304 to slide in, the internal array of the second baffle 102 is provided with a slide groove, the block 201 is slidably connected to the inside of the slide groove, the upper end array of the second baffle 102 is provided with a protrusion 103, the inside of the protrusion 103 is provided with a cavity 104, the upper end of the block 201 is fixedly connected to the limit plate 203, and the first spring 204 is fixedly connected to the limit plate 203.

[0030] In this embodiment, the first spring 204 can drive the block 201 to perform a reset movement, so that the block 201 is connected to the inside of the slot 305, and then the collision component 3 is fixed to the elastic coefficient that needs to be adjusted. The connecting rod 206 is an integrated structure between the slide bar 205 and the block 201. By pulling the handle 207, the block 201 can be driven to be pulled out of the slot 305, so that the connecting plate 304 loses the restraint fixed by the block 201, and then the collision spring 301 is reset to drive the impact plate 303 to impact the battery that needs to be tested, thereby achieving the detection effect.

[0031] Example 3
[0032] like Figure 1 As shown in FIG. 5 , on the basis of Example 1 and Example 2, the utility model provides a technical solution: preferably, the base 1 includes a support plate 105, the support plate 105 is fixedly connected to the rear end of the upper surface of the base 1, the buckle assembly 4 includes a clamping block 401, a movable groove 106 is provided at the front end of the support plate 105, the clamping block 401 is movably connected to the inside of the movable groove 106, the two ends of the bottom of the clamping block 401 are fixedly connected to the limiting block 403, the two sides of the inner wall of the movable groove 106 are provided with limiting grooves 107, the clamping block 401 is slidably connected to the inside of the movable groove 106 through the limiting block 403 and the limiting groove 107, the two sides of the front end of the clamping block 401 are provided with inclined surfaces 402, the upper end of the limiting block 403 is fixedly connected to the second spring 404, and the upper end of the second spring 404 is fixedly connected to the inner wall of the limiting groove 107.

[0034] The working principle of the lithium battery production detection device is described in detail below.
[0035] like Figure 1As shown in FIG5 , by pulling the pull rod 307, the top end of the collision spring 301 moves toward the upper surface of the base 1, so that the collision spring 301 generates elastic force, and the connecting plate 304 slides between the first baffle 101 and the second baffle 102. During the sliding process, the second sliding surface 306 and the first sliding surface 202 will rub against each other, so that the block 201 slides into the inside of the slide groove under the friction resistance of the connecting plate 304 and drives the first spring 204 to compress. When adjusted to the position required for testing, the first spring 204 can drive the block 201 to perform a reset movement, so that the block 201 is connected to the inside of the card slot 305, so that the collision assembly 3 is fixed as a whole, and then the battery is removed from the clamp. The two ends of the block 401 move toward the middle, and the battery will rub against the inclined surface 402 during the movement, so that the clamping block 401 slides inside the movable groove 106 under the friction of the battery and drives the second spring 404 to compress. When the battery completely slides into the clamping block 401, the second spring 404 is also in a compressed state, which will drive the clamping block 401 to perform a reset movement so that the clamping block 401 clamps the battery between the clamping block 401 and the support plate 105. Subsequently, pulling the handle 207 can drive the card block 201 to be pulled out of the card slot 305, so that the connecting plate 304 loses the restraint fixed by the card block 201, and then the collision spring 301 is reset to drive the impact plate 303 to impact the battery to be tested.
[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
