Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] see Figure 1-4 , the present invention provides a technical solution for hot-pressing equipment for film capacitors: a hot-pressing equipment for film capacitors, including a hot-pressing chassis 1 and a fixed frame 4, during the hot-pressing process, the top of the fixed frame 4 is pressed down The cylinder 5 presses the hot plate 3 on the capacitor carrier 8, and during the pressing process, the capacitor carrier 8 is changed once by the surface chan...

Abstract

The invention discloses hot-pressing equipment for a thin-film capacitor, which comprises a hot-pressing case and a fixed rack, wherein the fixed rack is fixedly arranged on the hot-pressing case, a lifting cylinder is arranged in the hot-pressing case, the output end of the lifting cylinder is fixedly connected with a hot-welding machine head, a plurality of uniformly distributed pressing and pasting assemblies are arranged on the lower end face of a hot pressing plate, each pressing and pasting assembly is mainly composed of a first spring, a telescopic rod and a pressing paster, a telescopic hole allowing the telescopic rod to penetrate out is formed in the hot pressing plate, in the downward pressing process of the hot pressing plate, the pressing paster on the lower end face of the hot pressing plate makes contact with the thin-film capacitor in advance, due to the fact that the width of the pressing paster is small and the pressing paster can be turned at will according to the shape of the touch thin-film capacitor, the pressing paster is attached to the touch thin-film capacitor, the upper surface and the bent corners of the touch thin-film capacitor are stressed more evenly, the touch thin-film capacitor is tighter after heat seal machining, and the pressing force and the pressing direction can be attached to the touch thin-film capacitor better.

Description

technical field [0001] The invention belongs to the technical field related to the production of film capacitors, and in particular relates to a hot-pressing equipment for film capacitors. Background technique [0002] Film capacitors use metal foil as an electrode, and it is laminated with plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate from both ends, and then wound into a cylindrical capacitor. According to the type of plastic film, it is called polyethylene capacitor (also called Mylar capacitor), polypropylene capacitor (also called PP capacitor), polystyrene capacitor (also called PS capacitor) and polycarbonate capacitor. A common film capacitor is made by winding metal foils such as aluminum as electrodes and overlapping plastic films. Hot pressing is one of the steps in the production of film capacitors. The main purpose of hot pressing is to complete the fixed capacity of the winding core under high temperature and high pressure wit...
