Technical Field

The utility model relates to a cut needle and contact pin integrated machine and construct especially relate to a needle and contact pin integrated machine are cut to no guide pin hole material area.

Background

The existing pin material belt is basically provided with a guide hole, the cutting mechanism cuts off products by positioning the guide hole, and the feeding system also takes the guide hole as a power supply point and feeds the products into the cutting mechanism by stirring the guide hole.

The needle belt cutting mechanism has the advantages that guide holes are required to be fed, qualified products cannot be accurately cut when the needle belt cutting mechanism meets a material belt without the guide holes, more waste materials are generated on the material belt due to the guide holes, and more material is wasted because the guide holes are not usually arranged in the products.

With a view to reducing the generation of waste material, the entry of unnecessary raw materials is reduced. The pin cutting process generates a plurality of scraps, which are basically guide holes and connecting sheets and are used in the production process. The guide holes in the needle belt are used for positioning the needle inserting position and feeding the driving point, but are not required parts of the needle inserting products, so that the guide hole parts become waste materials when the needle inserting products are cut off.

The existing pin belt feeding and cutting mechanism takes a guide hole in a pin belt as a reference, uses a positioning pin to position the guide hole, and then punches a pin product. If the guide hole portion is not present, an acceptable finished pin cannot be cut.

Aiming at cutting off the needle belt without the guide hole, the positioning point of the contact pin needs to be found again, and the qualified product is cut out accurately under the state that the guide hole is not used.

This non-holed needle tape cutting mechanism is a mechanism for performing precise cutting of a needle tape having no guide hole. For the transportation of the needle belt, the mechanism adopts a clamping and pushing mode, and two groups of cylinders are used for clamping, wherein one group is used for clamping the needle belt to drive the needle belt to transport, the other group is used for clamping and fixing, and the needle belt is clamped and fixed when moving in place. After the needle belt is fixed in place, the needle belt is positioned and confirmed by the ejector pin, and then the punching mechanism is used for cutting. The cutting part is that the guide needle guides the positioning point of the contact pin again, the contact pin is precisely positioned again, and then the cylinder pushes the cutting knife to cut off the contact pin connecting belt, so that a qualified contact pin product is obtained.

The existing pin inserting mode basically belongs to a material taking and inserting mode, and a material taking and transferring mechanism is needed to take the cut metal pins to an inserting position for pin inserting.
