Detailed Description

To facilitate an understanding of the utility model, the utility model will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 and 2, in a preferred embodiment, the tab positioning device of the present invention mainly includes a driving member 1, a base 2, a supporting member 3, and a positioning assembly 4. Wherein, driving piece 1 adopts the cylinder, and on driving piece 1 was located to base 2, driving piece 1's output was connected with base 2, and driving piece 1 can drive base 2 along vertical direction reciprocating motion. Support piece 3 is located on base 2, and support piece 3's upper end is equipped with the guide way 5 that extends along the horizontal direction, and locating component 4 locates guide way 5 and can follow guide way 5 horizontal slip. In this embodiment, the number of the positioning assemblies 4 is two to match the positive electrode tab and the negative electrode tab of the battery, and in other embodiments, the number of the positioning assemblies 4 may be more than two.

Specifically, locating component 4 includes slider 6, and

slider

6 and 5 sliding connection of guide way can adjust the distance between two locating component 4 through slider 6 to match the utmost point ear of different intervals, make the suitability of device wider. The upper end of the sliding block 6 is provided with a positioning block 7, the positioning block 7 is used for positioning the tab, the upper end of the sliding block is provided with a positioning groove 8, the positioning groove 8 is in a U shape, the width of the positioning groove 8 is preferably matched with the width of the tab, and when the driving piece 1 drives the positioning assembly 4 to move upwards in place, the tab can slide into the positioning groove 8 to be positioned.

In this embodiment, an in-place sensor 9 is disposed below the positioning groove 8 on the slider 6, and the in-place sensor 9 may be an existing sensor, such as an infrared sensor. The in-place sensor 9 can sense whether the tab is located in the positioning groove 8, when the positioning assembly 4 ascends in place and the in-place sensor 9 does not sense the tab, the tab is bent or deviated badly, and the in-place sensor 9 sends a signal to stop the heat sealing device, so that the tab or the battery is prevented from being damaged.

The sliding block 6 is provided with a locking screw 10 for fixing the position of the sliding block, and when the sliding block 6 is adjusted in place, the sliding block 6 can be fixed by screwing the locking screw 10, so that the phenomenon that the sliding block 6 slides to cause inaccurate positioning in use is avoided.

In a preferred embodiment, the supporting member 3 includes a mounting seat 11, a kidney-shaped hole 12 is formed on the mounting seat 11, and the mounting seat 11 is engaged with the kidney-shaped hole 12 through a bolt so as to be slidably connected with the base 2, so that the mounting seat 11 can slide relative to the base 2. In this embodiment, the length direction of the waist-shaped hole 12 is orthogonal to the extending direction of the guide groove 5, so that the positioning block 7 can be adjusted in the orthogonal first direction and second direction, and the use is more flexible and convenient.
