Embodiment

[0013] The film sealing tooling of the lead-acid battery liquid storage bottle involved in this embodiment, such as figure 1 , figure 2 , image 3 shown. The tooling is composed of a base 1, a cover plate 2, a soldering iron tip 4, and a reformed soldering iron tip 5. The reformed soldering iron tip 5 is made by threading the head of a waste general-purpose soldering iron tip, and the matching soldering iron tip 4 is made of a copper rod. Put the battery liquid storage bottle 3 into the hole 1 of the base, fix the battery liquid storage bottle 3 through the cover plate 2, and limit the height of the bottle mouth after welding; cover the bottle mouth of the battery liquid storage bottle 3 with PET / PE composite film, the soldering iron tip 4 is separated from the shoulder of the battery liquid storage bottle 3, heat seal the PE surface of the film and the bottle opening of the battery liquid storage bottle 3 with the soldering iron tip 4, then take out and cut off the excess...

Abstract

The invention discloses a film sealing tooling for a lead-acid battery liquid storage bottle, and belongs to the technical field of ammunition fuze products. The film sealing tooling is composed of abase (1), a cover plate (2), a welding head (4) and a modified welding head (5), wherein the modified welding head (5) is formed by processing waste universal welding heads into threads for modification. The liquid storage bottle (3) is put into the hole of the base (1) and the liquid storage bottle is fixed through the cover plate (2). A PET / PE composite film is coated on the mouth of the liquidstorage bottle, the PE surface of the film is heated and sealed with the mouth of the bottle by the welding head (4) and the excess film of the mouth of the bottle is taken out and cut off. The problems of low qualified rate and low efficiency in preparing the lead-acid battery liquid storage bottle can be solved and the screening process of the liquid storage bottle can be simplified and the screening period thereof can be shortened.

Description

technical field [0001] The invention belongs to the technical field of ammunition fuze products, and in particular relates to a film sealing tool for a lead-acid battery liquid storage bottle. Background technique [0002] At present, the 30mm precise distance bomb developed by the 152 factory has completed the physical bidding test. The on-board power supply for the fuze has the characteristics of small size, short activation time of 200ms to reach the working voltage of the fuze circuit, a wide operating temperature range of -40°C-+55°C, and a long storage life of 10 years. [0003] According to the structural characteristics of the power supply, the liquid storage bottle part of the power supply needs to be combined with the bottle body and the film by heat sealing. The soldering iron tip of the early product heat-seals the PE surface of the PET / PE composite film and the bottle body as a whole. This method has the problems of slow assembly speed, poor assembly consistenc...
