Abstract

A wire receiver 21 is mounted on the rear section of a wire cutting and stripping machine at output rollers 13 and is driven by a stepper motor 39 via a toothed belt drive 38. When stripped wires 156 are ejected from the output rollers, rotation of the receiver allows the wires to slide down to a collection part 22 so as to maintain wires collected in good order and to avoid bending.

Description

CUT TYPE WIRE RECEIVER The present invention relates to a cut type wire receiver which is mounted on the rear operation part of the conventional cutting stripper for effective collection of strands after wire cutting and stripping in facility of quantative bundle packing.

For any circuits connection. the insulating skin on both ends of electric wire must be stripped to provide bare wire for circuits connection. The conventional electric wire stripping must rely on a skillful electrician to make it with his skill but no 100% success is warranted. As electronic industry has moved into a full automation stage. slow speed by manual stripping can not satisfy the need of mass assembly. Thus, electric wire to be provided for connection must be stripped in advance and further be pressed conductive terminals in facility of automatic insertion operation. The stripping and terminal pressing job is finished by a stripping and terminal press. Referring to FIGs. 1A and 1B, it's a machine specially designed for cutting wire and stripping the insulating skin on the end of wire; such wire cutting stripper may cut the wire at various lengths, and strip both ends of wire at proper length. Because it adopts automatic and continuous stripping, its operation speed is very fast with good quality.

Though today there has cutting stripper with excellent cutting and stripping function, however some users indicate the wire products finished by such cutting stripper have been found bare wire ends are bent and wires collected are not well arranged to affect the subsequent bundling. According to the knowledge of the inventor, the cause lies in: the wires 12 finished by the cutting and stripping device 11 of cutting stripper 10 would drop to storage plane 14 of table after ejected from the output wheel set 13; such output of wires may have different negative impact to the wires at different lengths wherein for the wires 15 of shorter length when stripping length between both ends is different arrangement after ejected from the output wheel set 13 will be quite out of order and even short and long stripping ends are arranged in cross manner and this may cause a great trouble to the quantative bundling: because it may need to sort up the long and short ends manually for bundling again it thus increases unnecessary operation process. On the other hand, if for cutting longer wires 16, a stripping end 17 will be hanging down to the storage plane 14 of the machine owing to its dead weight when it is ejected from the output wheel set 13 while the other end 18 held within the output wheel set 13 continues to be ejected; as pushed forward the bent stripping end 17 of the wire will result in the deformation of bare wire 170 on the stripping end when it is pushed to the storage plane 14 of machine. Such result may give a great obstacle to terminal pressing on stripping end because bent bare wire will cause the terminal failing to put on the bare wire. In addition even if the bare end were not required for terminal pressing, in order for easy insertion of wires, they have to be straightened before bundling and this will result in needing extra labor.

In view of existing cutting stripper having the defect of product as mentioned above, tbe inventor therefore have successfully designed a wire receiver to match cutting stripper subject to such shortcomings, and said wire receiver has a spline shaft driven by motor which is distributed on the rear section of output wheel set of cutting stripper. With the control of timing running of motor, the spline shaft may turn around at 90 degrees; thus the wires ejected from the output wheel set will enter the slot of spline shaft to fall into the wire collector below the spline shaft as a result of spline shaft turning by 90 degrees to finish wire reception in good order.
