A flat thin film capacitor core rubber wrapping device

Abstract

The invention discloses a flat thin-film capacitor core rubber coating device. The flat thin-film capacitor core rubber coating device comprises a rubber belt unreeling arm, a working table top, rubber belt guide blocks and a capacitor core positioning block; the rubber belt guide blocks and the capacitor core positioning block are fixed to the working table top, the two rubber belt guide blocks are symmetrically arranged, the distance between the two rubber belt guide blocks is larger than the width of a Mara rubber belt by 1-2 mm, the capacitor core positioning block is arranged behind the rubber belt guide blocks and closely attached to the rubber belt guide blocks, a first groove with the distance larger than the width of the Mara rubber belt by 1-2 mm is formed in the side, close to the rubber belt guide blocks, of the capacitor core positioning block, a second groove with the distance larger than the length of a capacitor core by 1-2 mm is formed in the other side of the capacitor core positioning block, a third groove is formed in the lower portion, the depth of the third groove is 2 mm, and the width of the third groove is larger than the width of the Mara rubber belt by 1-2 mm. By means of the flat thin-film capacitor core rubber coating device, the rubber coated capacitor core is positioned, the rubber belt is guided by the rubber belt guide blocks, the problem of an uneven end face easily caused during manual rubber coating is solved, the runner coating efficiency is improved, the structure is simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of capacitor processing equipment, in particular to a flat film capacitor core rubber covering device. Background technique [0002] For MEA and MPA flat film capacitors, the core must be wrapped with Mylar tape longer than the core after the core is welded with the CP line, and it is used for end face epoxy resin encapsulation. One of the existing encapsulation methods is to customize the flat film capacitor. Film capacitor core automatic encapsulation machine; its equipment is often complex in structure and has a high failure rate. The second method is to use manual encapsulation, which can easily cause uneven end faces and affect the product qualification rate. Contents of the invention [0003] The purpose of the present invention is to provide a flat thin film capacitor core glue wrapping device, which has a simple structure, low price, flat glue wrap end face and high product qualification rate. ...

Problems solved by technology

[0002] For MEA and MPA flat film capacitors, the core must be wrapped with Mylar tape longer than the core after the CP line is welded on the periphery, and it is used for end face epoxy resin encapsulation. One of the existing encapsulation methods is to customize the flat film capacitor. Film capacitor core automatic encapsulation machine; its equipment is often complex in structure and has a high failure rate

The second method is to use manual encapsulation, which will easily cause uneven end faces and affect the product qualification rate
