Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing equipment, in particular to a cap assembly fixture and a cap assembly feeding mechanism. Background Art

[0002] The cap group is an important component of the battery. It not only carries the electrical connection between the positive and negative electrodes inside the battery, but also is responsible for the safety sealing of the battery to prevent electrolyte leakage and the intrusion of external impurities. During the battery production process, due to the small size and thin thickness of the cap group, it is a relatively difficult process to fix the cap group for transportation.

[0003] The existing cover group jig for fixing the cover group usually opens a plurality of holes of the same shape as the cover group on the jig body, and then puts the cover group into the holes for fixing. The cover group fixed in this way is still easy to get loose. In addition, even the cover groups produced in the same batch may have slightly different sizes due to production process and other reasons. As a result, some slightly larger cover groups are difficult to put into the holes of the jig, while some slightly smaller cover groups are more likely to fall out of the holes of the jig.

The drive cylinder 16 is arranged below the cover assembly fixture, and a pull block 17 is installed on the output end of the drive cylinder 16. The pull block 17 is rectangular, and the length direction of the pull block 17 is the same as the length direction of the pull plate 12. The width direction of the pull block 17 extends upward, and the top of the pull block 17 abuts against the bottom of the pull plate 12. When the output end of the drive cylinder 16 retracts, the pull block 17 drives the pull plate 12 to move, and then drives the movable plate 11 and the second base block 3 to move, increasing the distance between the second base block 3 and the first base block 2, thereby increasing the accommodating chamber 1. At this time, the cover assembly can be inserted into the accommodating chamber 1, and then the output end of the drive cylinder 16 extends out, the pull plate 12 is separated from the abutment state with the pull block 17, and the first elastic member 10 rebounds, so that the second base block 3, the movable plate 11 and the pull plate 12 are reset, and then the cover assembly is clamped by the first card slot 4 and the second card slot 5, and the loading of the cover assembly is completed.

Rectangular openings are opened on the turntable 19 corresponding to the installation positions of the cover assembly jigs, and the pull plate 12 extends from the openings. The drive cylinder 16 is arranged below the turntable 19 through a support assembly. As the turntable 19 rotates, the cover assembly jigs on the turntable 19 pass through the position of the drive cylinder 16 in turn. When the pull plate 12 of a certain cover assembly jig rotates with the turntable 19 to contact the pull block 17 of the drive cylinder 16, the turntable 19 stops rotating, and the output end of the drive cylinder 16 retracts, so that the second base block 3 moves and the accommodating chamber 1 expands. At this time, the cover assembly can be inserted into the cover assembly jig, and then the output end of the drive cylinder 16 extends. The second base block 3 is reset and clamped under the action of the first elastic member 10. At this time, the cover assembly jig is loaded, and then the turntable 19 continues to rotate, and the above operation is repeated until all the cover assembly jigs on the turntable 19 are loaded. The cover assembly loading mechanism in this embodiment has a good effect on fixing the cover assembly due to the application of the above-mentioned cover assembly jig, and has a high degree of automation, which is suitable for automatic operation of the assembly line.
