Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this utility model is usually placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying 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 construed as a limitation to the present utility model.

[0023] Please refer to Figures 1-3 , in this embodiment, a sealing nail feeding device includes a buffer part 3 connected to one end of a feeding track 2 for storing multiple sealing nails; the buffer part 3 includes a guiding tube 31, the upper end of the guiding tube 31 is selectively connected to the feeding track 2, and a limiting mechanism 32 is provided at the lower end. The limiting mechanism 32 includes an upper ring body 321 and a lower ring body 322 arranged concentrically. The guiding tube 31, the upper ring body 321, and the lower ring body 322 are movably connected through a guide rod 323, so that both the upper ring body 321 and the lower ring body 322 can perform linear motion of approaching or departing from the guiding tube 31. A blanking limiting part 324 is provided on the lower ring body 322. The blanking limiting part 324 includes a base ring 3241, an elastic member 3242 arranged below the base ring 3241 and driving its axial floating, and a first limiting block 3243 circumferentially arranged above the base ring 3241; the first limiting block 3243 is bent towards the center of the lower ring body 322; the blanking limiting part 324 further includes a second limiting block 3244 arranged between the upper ring body 321 and the lower ring body 322, and both ends of the second limiting block 3244 are selectively abutted against the upper ring body 321 and the base ring 3241 respectively. In the case of no extrusion, the lower ring body 322 is suspended below the upper ring body 321, the elastic member 3242 naturally extends, and pushes the base ring 3241 above it upward, so that the bending structure at the top of the first limiting block 3243 gathers towards the center of the base ring 3241, blocking the falling of the upper sealing nails; when the lower ring body 322 is subjected to an upward pressure, the lower ring body 322 moves upward, the bottom of the second limiting block 3244 squeezes the base ring 3241 to move it downward, the first limiting block 3243 moves downward synchronously, and the bending structure of the first limiting block 3243 expands outward, forming a channel for the sealing nails to fall.

[0024] Further, the stapling device further includes a turntable 4; a plurality of mounting holes are circumferentially formed in the turntable 4, and each mounting hole is provided with a buffer portion 3. The turntable 4 rotates periodically at a preset angle, and can continuously buffer multiple sealing nails in each buffer portion 3, improving the buffer capacity.

[0025] Further, an arc-shaped notch 21 is formed at the connection end of the feeding track 2 and the guiding tube 31. The arc-shaped notch 21 is semi-circular and is clamped on the outer wall of the guiding tube 31, increasing the reliability of the connection between the feeding track 2 and the guiding tube 31, and not hindering the connection between the feeding track 2 and the guiding tube 31 when the turntable 4 rotates.

[0026] Further, an annular accommodation cavity 3221 is formed downward on the top surface of the lower ring body 322, and the elastic member 3242 and the base ring 3241 are both arranged in the accommodation cavity 3221.

[0027] Further, a guiding bin 3211 that penetrates up and down is formed in the upper ring body 321 for the second limiting block 3244 to pass through, and the guiding bin 3211 has a wedge-shaped structure that is smaller at the top and larger at the bottom. The guiding bin 3211 plays a role in positioning the second limiting block 3244 and guiding the displacement of the second limiting block 3244 when it is pressed. When being squeezed, the second limiting block 3244 moves upward, and the top thereof penetrates out of the guiding bin 3211.

[0028] Further, a groove 311 corresponding to the guiding bin 3211 is formed at the bottom of the guiding tube 31. When the second limiting block 3244 moves upward to the highest position, the top of the second limiting block 3244 abuts against the groove 311. The groove 311 is beneficial to improving the compactness of the overall structure.

[0029] Further, the second limiting block 3244 includes a thin portion 32441, a transition portion 32442, and a thick portion 32443 that are integrally connected from top to bottom; a stop member 32444 is provided on one side of the thick portion 32443 close to the center of the upper ring body 321. When not being squeezed, due to the stop member 32444 retracting into the accommodation cavity 3221 under the gravity of the sealing nail, the sealing nail is fixed above the first limiting block 3243, and the first limiting block 3243 achieves the effect of preventing the sealing nail from falling.

[0030] Further, the stapling device further includes a support limiting block 1 sleeved on the outer periphery of the guiding tube 31, and the support limiting block 1 abuts against the upper end surface of the turntable 4. The guiding tube 31 and the mounting hole of the turntable 4 are connected with a clearance fit. The support limiting block 1 is fixedly arranged on the outer periphery of the guiding tube 31, playing a supporting role for the guiding tube 31. In addition, the support limiting block 1 serves as a grasping contact point, which is beneficial to the smooth grasping of the robotic arm.

[0031] Furthermore, the turntable 4 includes a turntable body 41, a rotating shaft 42 arranged at the bottom of the turntable body 41, and a base 43 arranged at the bottom of the rotating shaft 42. The base 43 has a built-in rotating motor to drive the rotating shaft 42 to rotate, thereby driving the turntable body 41 to rotate.

[0032] When the utility model is in use, the vibration plate 5 continuously conveys the sealing nails to the buffer part 3 through the feeding track 2, and the sealing nails slide down from the guide tube 31 to the bottom one by one. Since the buffer part 3 is suspended on the turntable 4, the limit mechanism 32 is in a pressure-free free state, and the guide tube 31, the upper ring body 321, and the lower ring body 322 maintain the maximum distance from each other. Under the action of the elastic member, the first limit block 3243 gathers toward the center of the base ring 3241 to seal the bottom of the guide tube 31, and the sealing nails are stacked in the guide tube 31 in sequence. After the material is full, the turntable 4 rotates a preset angle to make the feeding track 2 abut against another adjacent buffer part 3, and repeat the above process, and the sealing nails are stacked in the guide tube 31 one by one. The mechanical arm grabs the full buffer part and places it in the battery cell installation area, squeezes the buffer part downward, and the first limit block 3243 moves downward and expands outward, so that a channel is formed at the bottom of the guide tube 31, and the sealing nails fall smoothly into the injection hole. Lift the buffer part upwards, and the first limit block 3243 will automatically retract toward the middle to prevent the sealing nail from falling. Move the buffer part to another battery cell, and then squeeze downwards to release the nail.

[0033] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0034] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
