Parallel movement winding needle mechanism

The invention discloses a parallel movement winding needle mechanism, and relates to the technical field of lithium battery processing. Comprising at least two half winding needle assemblies, the half winding needle assemblies are symmetrically arranged, and each half winding needle assembly comprises a winding needle cylinder, a winding needle rod arranged in the winding needle cylinder, a pressing strip pull rod movably arranged on the winding needle rod and a diaphragm pressing strip installed in the winding needle cylinder from outside to inside in a stacked mode; a guide block with one end extending into the pressing strip pull rod is arranged on the diaphragm pressing strip; and the winding needle seat assembly comprises a winding needle seat main body and a radial spring. Compared with a conventional winding needle of a shear type structure, the compatibility of the winding needle to a large-breadth battery is obviously improved, the middle push-pull locking assembly drives the half winding needle asse
