[0030] Example

[0031] like Figure 1 As shown, this embodiment provides a nozzle extraction tool for cylindrical batteries, including a box-shaped base 10. Four slide rails 11 along the X-axis direction are arranged on the bottom plate of the base 10. The four slide rails 11 are aligned in pairs and divided into two groups, and a slide seat 12 is slidably installed on each group of slide rails 11.

[0032] Preferably, in the present embodiment, a suction nozzle tool for cylindrical batteries is provided with a rotatable shaft 14 installed in the middle of the base 10, and a driving bevel gear 15 is fixedly connected to the shaft 14. The two sides of the driving bevel gear 15 are respectively meshed with a first driven bevel gear 16 and a second driven bevel gear 17, and the first driven bevel gear 16 and the second driven bevel gear 17 are coaxially arranged. The first driven bevel gear 16 and the second driven bevel gear 17 are respectively fixedly connected to the first driven bevel gear 16 and the second driven bevel gear 17, and the first screw rod nut and the second screw rod nut are respectively screwed to the first screw rod and the second screw rod, and the first screw rod nut and the second screw rod nut are respectively fixedly connected to a slide 12.

[0033] Preferably, in the present embodiment, a nozzle extraction tool for cylindrical batteries has a crank connected to each end of the rotating shaft 14, and the crank rotates the driving bevel gear 15, the first driven bevel gear 16 and the second driven bevel gear 17 to drive the two slides 12 to slide on the slide rail 11, thereby adjusting the distance between the two slides 12 to adapt to battery nozzles of different width specifications.

[0034] Preferably, in the nozzle extraction tool for cylindrical batteries of this embodiment, a plurality of nozzle extraction assemblies 13 are provided on the slide 12 for extracting the nozzles on the cylindrical batteries.

[0035] like Figure 2 As shown, the suction nozzle assembly 13 includes a mounting plate 131, an articulated frame 132 and a buckle 133. The mounting plate 131 is fixedly connected to the slide 12, two articulated frames 132 are fixedly connected to the mounting plate 131 in pairs, and the buckle 133 is hinged on the articulated frame 132 to form a set of battery nozzle buckle connection structures. A limit stopper is provided at the tail of the buckle 133. When the limit stopper of the buckle 133 abuts against the top surface of the articulated frame 132, the bottom surface of the head of the buckle 133 forms an angle of 80°-90° with the inner side wall of the articulated frame 132. Such a design enables the buckle 133 to stably clamp the battery nozzle.

[0036] In order to ensure that the buckle 133 can maintain a stable clamping state when not subjected to external force, a torsion spring is provided between the buckle 133 and the hinge frame 132. The torsion spring is used to elastically support the limit stopper of the buckle 133 to abut against the top surface of the hinge frame 132 when the buckle 133 is not subjected to external force.

[0037] In order to prevent the buckle 133 from interfering with the hinge frame 132 during the rotation process, an avoidance groove is provided on the inner side wall of the hinge frame 132 to accommodate the buckle 133 when the buckle 133 rotates downward.

[0038] In actual use, the base 10 is connected to the mechanical arm, and the distance between the two slides 12 is adjusted to adapt to battery nozzles of different widths, so that the battery nozzle is aligned with the nozzle assembly 13, and the battery nozzle approaches and presses the buckle 133. When the battery nozzle is separated from the buckle 133, a group of buckles 133 lock the battery nozzle under the action of the torsion spring, and the battery nozzle is pulled out under the drive of the mechanical arm. When the battery nozzle is pulled out, the mechanical arm rotates 90 degrees, so that the base is in a vertical state, and the battery nozzle falls off.

[0039] In order to improve the stability of the slide seat 12 during the sliding process, a guide frame 18 is further provided on the base 10. The guide frame 18 is provided with a plurality of guide bars along the X-axis direction, and the mounting plates 131 are slidably arranged on both sides of the guide bars.

[0040] In order to realize automatic detection and improve production efficiency, a through-beam photoelectric switch is also provided on both sides of the articulated frame 132. A through hole for avoiding position is also provided on the articulated frame 132. The through-beam photoelectric switch passes through the through hole for avoiding position of the articulated frame 132 and is used to detect whether there is any residual battery nozzle on the nozzle assembly 13. When there is material, the photoelectric switch will send a signal to remind the operator to remove the residual battery nozzle on the tooling and then carry out the next round of battery nozzle extraction operation.

[0041] In summary, the nozzle extraction tool of the utility model can adapt to the extraction operation of battery nozzles of different width specifications by adjusting the distance between the two slide seats. At the same time, the tool has a simple structure, is easy to operate, and improves production efficiency.

[0042] Based on the above ideal embodiments of this application, the relevant staff can make various changes and modifications without departing from the technical concept of this application through the above description. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
