Description
Technical Field
The invention relates to a production method of copper foil flexible connection and an automatic production system applying the production method.
Background
In the field of high-current connection in electrical equipment, copper bars are used for connection in the past, but the copper bars are limited by the application conditions of the equipment, so that a copper foil flexible connection product is produced at present, wherein a plurality of copper foil sheets with the thickness of about 0.1mm are stacked together, and then two ends of the copper foil sheets are formed by high-molecular diffusion welding and melt pressing to be used as an electric connecting piece; the flexible connection in the form of copper foil lamination has the following advantages: gaps exist among the copper foils, so that heat dissipation is facilitated; the device displacement generated by vibration can be eliminated; the larger the surface area, the more stable the transmission current. Compared with the flexible connection of copper braid belts, the flexible connection of copper foil is easier to customize the size in an individualized way, and the current which can be carried is larger, so that the flexible connection of copper foil is widely applied to high-power electrical equipment, such as new energy automobiles.
The core of the copper foil flexible connection is copper foil, which is formed by selecting a coiled copper foil belt with corresponding width according to requirements, cutting a set length, arranging a plurality of pieces into a stack, sending the stack into welding equipment, and welding copper blocks at two ends.
The copper foil is thinner, and is easy to heat and conduct heat during welding, so that the part left outside the welding head is also heated to generate high temperature, namely the operation risk is high, and the copper foil is easy to oxidize when being exposed in the air under the high-temperature condition; in order to solve the problem of oxidization of the flexible connection of the copper foil in the welding process, a large amount of water is sprayed on the copper foil outside the welding machine to cool the copper foil in the welding process at present; however, the impurities in the water are more, and a plurality of specks are formed on the copper foil when the copper foil is cooled. Therefore, after the product is welded, the working procedures such as polishing and the like are also needed to restore the bright metallic color of the soft connected surface of the copper foil, but the copper foil inside cannot be deeply treated.
The copper foil flexible connection is applied to the field of high current, and the current is subjected to skin effect and is mainly transmitted on the surface of a conductor, so that the surface quality of the copper foil can influence the application effect of a final product.
How to improve the welding quality of the copper foil flexible connection, in particular to the surface quality of the copper foil which does not participate in the pressure welding part after welding, is an important subject in the current copper foil flexible connection production and manufacturing field.

Detailed Description
The invention is further described below with reference to the drawings and specific examples.
The invention provides a method for producing a copper foil flexible connection, which comprises the following steps:
step 1: forming copper foil; blanking out a copper foil single sheet from the copper foil strip material by using blanking equipment;

The loading and unloading device 5, which is a multi-degree-of-freedom (more than 4 degrees of freedom) mechanical arm in this embodiment, stacks and clamps the copper foil to be welded on the through-wall delivery device 4 by the mechanical arm, and then places the copper foil into the welding machine 6.
Before the copper foil to be welded is stacked, clamped and placed in the welding machine 6 by the feeding and discharging equipment 5, a step 3 is required to be implemented, and the step can be performed by any one of the delivery line 2, the through-wall delivery device 4 or the feeding and discharging equipment 5, or can be performed by a plurality of stations respectively.
