Gluing device

The utility model provides a gluing device. The gluing device comprises a base table, a limiting mechanism and a gluing part, the gluing part is connected to the base table to glue the battery shell, the limiting mechanism is arranged in a limiting area of the base table and comprises two positioning pieces and two adjusting pieces, and one positioning piece and one adjusting piece are arranged on the two sides of the limiting area in the second direction correspondingly; the other positioning piece and the other adjusting piece are arranged on the two sides, in the third direction, of the limiting area respectively, the shell is contained between the two fixing pieces and the two adjusting pieces, the positioning pieces are fixedly arranged relative to the limiting area, the positioning pieces play a role in positioning the battery shell, and the adjusting pieces are movably arranged relative to the limiting area. The limiting mechanism can contain various shell sizes, the adjusting piece and the positioning piece can clamp the battery shell, the problem that the gluing condition of the battery shell is poor due to the fact that the battery shell deflects in the second direction and/or the third direction is solved, and the reliability of the gluing device is improved.
