Description

Technical Field

[0001] The utility model relates to the technical field of LED bulb lamp production, in particular to a wire inserting machine with the functions of stripping and cutting wires. Background Art

[0002] An LED bulb is a bulb with an internal light source of an LED chip and a spherical appearance. The light source substrate is an important component of the LED bulb. During the production process of the LED bulb, wires need to be plugged into the wire holes of the light source substrate. Before plugging in, the insulation layer at both ends of the wires needs to be removed. Currently, wires are plugged into the wire holes of the light source substrate through an all-in-one wire stripping, cutting and plugging machine.

[0003] For example, the patent with patent number CN220914734U includes a frame, and a wire feeding mechanism, a wire cutting mechanism, a material guiding mechanism, a material receiving mechanism and a wire clamping mechanism arranged in sequence from top to bottom, the wire clamping mechanism is connected to a lifting mechanism, and the wire feeding mechanism, the wire cutting mechanism, the material guiding mechanism, the material receiving mechanism and the lifting mechanism are all installed on the frame; the wire feeding mechanism is used to convey wire, the wire cutting mechanism is used to cut off the plastic sheath and wire of the wire conveyed by the wire feeding mechanism, the material guiding mechanism is used to receive the plastic sheath and wire of the wire cut off by the wire cutting mechanism and guide the wire to the material receiving mechanism, and the material receiving mechanism is used to receive the wire guided by the material guiding mechanism.

[0004] Although the above-mentioned device can automatically strip and cut the wires and insert the cut wires into the wire holes of the light source substrate, it does so by retracting the wire feeding mechanism. During the retraction process, the wires are always in contact with the wire cutting mechanism for stripping. Since the wire feeding mechanism uses a wheel group with a tensioning function to feed the wires, and the wires are always in contact with the wire cutting mechanism during stripping, the longer the stripped wire is, the more likely it is that the wire will slip, resulting in errors in the stripping length. The length of the wire cut subsequently will not meet the requirements, and the stripped wire may easily bend. Utility Model Content
