Abstract
Description
Technical Field
[0001] The utility model relates to a detection device, in particular to an automatic detection device for wire slippage of a capacitor cover, and belongs to the technical field of capacitor packaging equipment. Background Art
[0002] In the process of packaging the substrate self-supporting capacitor, the impregnated battery cell, cover plate and aluminum shell need to be sent to the packaging machine for sealing operation. Since the positive and negative terminals at the bottom of the cover plate are connected to the foil strips on the battery cell, a metal sliding wire (commonly known as a washer) needs to be installed on the positive and negative terminals to increase the connection effect. However, when the cover plate is sent to the packaging machine, the sliding wire on the terminal often falls off. If the falling of the sliding wire washer cannot be found in time, but the cover plate is directly packaged with the aluminum shell and the battery cell, the electrode sealing in the cover plate will be insufficient, and the assembled capacitor cannot be put into use. In the existing packaging equipment, the cover plate is usually placed on a special tray manually, and the cover plate is transferred to the aluminum shell (including the battery cell) by a fixture, and then riveted. In this process, whether the sliding wire washer in the cover plate falls off cannot be effectively detected. Therefore, further improvement is needed. Utility Model Content

[0023] Specifically, in this embodiment, the first motor 17 drives the upper plate 3 to move in the horizontal direction of the packaging machine body 19 until it moves to the top of the pallet 1 and the cover plate workpiece 18. The cover plate workpiece 18 is placed on the pallet 1 manually.
[0024] Furthermore, the transfer fixture assembly also includes a lifting column 7; the lifting column 7 passes through the upper plate 3; the upper end of the lifting column 7 is connected to the first cylinder 8; the first cylinder 8 is arranged on the surface of the upper plate 3; and a slot 9 is arranged on one side of the lower part of the lifting column 7.
[0025] Furthermore, the slot 9 and the axis of the lifting column 7 are perpendicular to each other; a spring is arranged in the slot 9; the spring is connected to the wedge block 10; and the inclined surface of the wedge block 10 faces the cover plate workpiece.
[0026] Specifically, in this embodiment, after the upper plate 3 moves to the top of the cover plate workpiece 18, the lifting column 7 descends under the action of the first cylinder 8; when the lifting column 7 descends, the wedge block 10 will contact the edge of the cover plate workpiece 18, and the cover plate workpiece 18 will push the wedge block 10 to overcome the elastic force of the spring and move into the slot 9 until the lifting column 7 continues to descend and the wedge block 10 abuts against the side wall of the cover plate workpiece 18 and stops descending; the wedge block 10 clamps the two sides of the cover plate workpiece 18 from two directions under the action of the elastic force. With the continued movement of the upper plate 3, the cover plate workpiece 18 can be transferred to the next aluminum shell station.
[0027] Furthermore, the rotating rod 2 is connected to the bottom center of the lifting column 7 through the rotating shaft 11; the rotating shaft 11 is sleeved with a lower ring 12; the lower ring 12 is provided with an angle limiting column 20; the bottom of the lifting column 7 is provided with an upper ring 13; the upper ring is provided with an angle limiting groove; the angle limiting column is connected to the angle limiting groove 21.
[0028] The rotation process of the rotating rod 2 cannot exceed the angle range of the corner limit slot, ensuring that the rotating rod 2 can be rotated to the corresponding position.
[0029] Furthermore, the refractor 14 is arranged on the surface of the rotating rod 2; after rotation, the position of the refractor 14 is opposite to the installation space of the sliding wire washer between the cover plate and the electrode; there are two photoelectric receiving elements, which are arranged on the surface of the rotating rod 2; there are two refractors 14; the photoelectric receiving elements are located outside the two refractors 14.

[0031] Specifically, in this embodiment, after the electrode 19 is installed in the cover plate workpiece 18, a gap will be formed between the electrode 19 and the cover plate workpiece 18, and this gap is used to install the sliding washer. After the wedge block 10 clamps the cover plate workpiece 18, the rotating rod 2 at the bottom of the lifting column 7 is rotated so that the light refractor 14 on the rotating rod 2 can face the above gap; and the photoelectric detection element 15 at the bottom of the upper plate 3 is also facing the gap; if the sliding washer falls, resulting in the loss of obstruction in the gap, the photoelectric detection element 15 can emit infrared rays to the refractor 14, and the photoelectric receiving element 16 provided on the rotating rod 2 can receive the above infrared rays, and it is determined that the sliding washer has fallen; if the three cannot be connected, there is no abnormality in the installation state of the washer.
