AI Technical Summary

Technical Problem

Existing cord lamp production equipment is prone to springback when cutting the plastic part, resulting in uneven exposed copper wire length, which affects the inaccurate position of the lamp beads and poor welding. Especially when the lamp spacing is 2.5 cm or less, it is difficult to weld stably and the appearance is poor.

Method used

The upper and lower cutting heads move in opposite directions, cutting the plastic part with horizontally arranged blades, and cutting the copper wire along the axis using axial blade grooves. This ensures stable separation of the copper wire from the plastic part, avoids compression of the plastic part, and achieves uniform LED spacing and aesthetics.

Benefits of technology

This achieves stable separation between the copper wire and the plastic part, ensuring the uniformity and aesthetics of the LED spacing, and improving the welding effect, especially the welding stability under tight spacing conditions.

Abstract

This invention relates to the field of cord lamp technology, specifically to a cord lamp production equipment. The invention includes a cord cutting device, comprising a main support, a lifting cylinder mounted on the upper end of the main support, the lifting cylinder driving downwards to connect to a lifting seat, an upper cutting head mounted on the lifting seat, a worktable mounted on the main support, and a lower cutting head mounted on the worktable. The upper and lower cutting heads correspond to each other, with the upper cutting head movably positioned above the worktable. Both the upper and lower cutting heads have horizontally arranged blades, with the upper cutting head having an axially arranged blade. This invention uses the horizontally arranged blades to cut the plastic portion of the cord horizontally, and the axially arranged blades of the upper cutting head to cut the plastic portion of the cord axially, thus achieving the cord cutting effect without compressing the plastic portion of the cord, maintaining overall aesthetics. Simultaneously, the cutting spacing can be adjusted to enhance the variation effect of the lamp beads welded to the cord.
