DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0018] Please refer to Figure 1-6, the utility model provides a technical solution: a single-cell pole ear cutting device, which includes a frame 1, on which a feeding and leveling mechanism 2, a picking and transferring component 3, a vision inspection component 4, a platform component 5 and a blanking component 6 are respectively installed. The vision inspection component 4 includes an auxiliary light source and a detection camera, and the detection camera is located below the auxiliary light source.

[0019] The feeding and leveling mechanism 2 includes a rotary divider 201 and a vertical frame 203. The output end of the rotary divider 201 is installed with a circular insulating turntable 202. The vertical frame 203 is located on one side of the insulating turntable 202. A vertically downward cylinder a204 is installed on the side of the vertical frame 203 through a support. A pressing block 205 is fixedly installed on the piston rod of the cylinder a204. Four positioning jigs are evenly arranged along the circumference on the upper side of the insulating turntable 202. The positioning jigs are used to clamp and place the single cell with the pole ear to be cut. When the single cell rotates with the insulating turntable 202 and passes by the pressing block 205, it pauses, and then the cylinder a204 pushes the pressing block 205 downward and presses on the pole ear to level the pole ear. The picking and transferring component 3 includes a support frame 301. A horizontal linear module 302 is installed on the upper part of the support frame 301. The linear module 302 is provided with a moving carrier. A vertical cylinder b303 is fixedly installed at the lower end of the carrier. A downward servo motor a304 is installed on the sliding table of the cylinder b303. A suction cup gripper 305 is installed on the output shaft of the servo motor a304. The servo motor a304 drives the suction cup gripper 305 to rotate to adjust the orientation of the single cell. The suction cup gripper 305 is composed of multiple vacuum suction cups.

[0020] After being leveled by the feeding and leveling mechanism 2, the single cell is grabbed by the picking and transferring component 3 and sent to the vision inspection component 4 for inspection. The vision inspection component 4 takes pictures to detect whether there are defects in the shape of the single cell. Then it is placed on the platform component 5. The platform component 5 includes a vacuum suction and positioning platform 501 and a defective product placement platform 502. The lower part of the vacuum suction and positioning platform 501 is driven by a lifting cylinder. After the single cell is placed on the vacuum suction and positioning platform 501, the next step of cutting is carried out.

[0021] The blanking component 6 includes a bottom plate 601 and a cutting press 602. The cutting press 602 is provided with a cutting tool mechanism 606 that moves up and down. The cutting press 602 is installed between the bottom plate 601 through a horizontal slide rail 603. A rack 604 parallel to the slide rail 603 is fixedly installed on the bottom plate 601. A downward servo motor b605 is installed on the side of the cutting press 602. The output of the servo motor b605 is installed with a gear meshing with the rack 604. Therefore, the cutting press 602 can move horizontally. When the two cutting presses 602 approach each other, the pole ears at both ends of the single cell are inserted into the cutting tool mechanism 606, and the cutting tool mechanism 606 can act to cut the pole ears simultaneously. The blanking component 6 is used to cut the pole ears of the single cell to achieve the required shape and size (this device is applicable to single cells with two sets of opposite pole ears).

[0022] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model, and the scope of the present utility model is defined by the appended claims and their equivalents.
