Description

Technical Field

[0001] The invention belongs to the field of automation equipment, and in particular relates to an automatic machine for assembling connector pins. Background Art

[0002] New energy vehicle connectors are a type of connector that is specifically used in new energy vehicles to connect the power system of electric vehicles with other devices. Compared with traditional high-voltage and high-current connectors and low-voltage automotive connectors, new energy vehicle connectors have higher requirements in design and application. Its structure is as follows Fig.15 As shown, it includes: a plastic shell and a pin inserted into the plastic, and the end of the pin has a degree of bend. In order to improve the assembly efficiency of the product and prevent workers from touching the pins with their hands (sweat stains on their hands can easily cause the pins to rust). At present, automatic machines are usually used to complete the assembly. The current pin insertion machine structure is shown in the Chinese utility model patent with the authorization announcement number "CN 109742636 B" and the name "A fully automatic pin insertion machine". In order to facilitate the transmission of the pin, it is first necessary to pass through another assembly machine to clamp the pin into the pin cassette, and then transmit it to the pin separation station to separate the pin from the cassette, and finally rivet the pin into the plastic shell through a riveting mechanism. The disadvantages are: 1. The assembly needs to be completed on two automatic machines, the work efficiency is low, and because the pin is clamped on the cassette, it is easy to fall off during handling or transmission; 2. There is no bending function.

[0003] In response to the above problems, some automatic machines that directly assemble the material pins are also used in the market. The advantage of this type of automatic machine is that the material pins can be directly transmitted, and then the pins are cut off by the first cutting head on the automatic machine, and then riveted. However, the common disadvantages are: 1. The stability and accuracy of cutting, bending and riveting are poor, and the cutting position cannot be adjusted; 2.
