Jig and method for quick maintenance of sealing head

The invention belongs to the technical field of production and manufacturing of lithium batteries, and particularly relates to a jig for quick maintenance of a sealing head. The jig comprises a handleand a main body part connected with the handle, grooves are correspondingly formed in the upper end surface and the lower end surface of the main body part, the depth of each groove is 2-20 mm, the width of each groove is W-sealing head + delta W, the W-sealing head is the width of the sealing head, the delta W is 0.3 mm to 3.0 mm, the length of each groove is L-sealing head + delta L, the L-sealing head is the length of the sealing head, and the delta L is 0.3 mm to 5.0 mm. In addition, the invention further provides a method for quick maintenance of the sealing head. According to the method, teflon is adhered to the jig, the jig is placed between an upper sealing head body and a lower sealing head body, then the upper sealing head body and the lower sealing head body are combined, and the teflon is automaticall
