Description

Film pasting jig inside product Technical Field The utility model relates to the technical field of film sticking jigs, in particular to a jig for sticking a film in a product. Background At present, in the product, the manual work can not be carried out the product of film pasting manually, generally all needs the manual work to carry out film pasting with the help of people's eyes and hand slowly with tweezers, and is extremely low like this, and because no positioner can assist, the precision is very poor, and the rework rate is also very high, does not have mass production at all. Although a large amount of manpower and financial resources can be input, full-automatic equipment is developed to perform operation, and CCD is used for accurate positioning, when the order quantity is not large, the cost is high, and the maintenance is often difficult. Aiming at the problems, the utility model provides a jig for sticking a film in a product. Disclosure of utility model The utility model provides a film pasting jig in a product, which solves the problems that in the prior art, a product which cannot be manually pasted in the product is manually pasted, the film pasting is generally carried out by manually using tweezers by means of human eyes and hands, the efficiency is extremely low, and because a positioning device is not used for assisting, the precision is poor, the rework rate is high, the mass production is not carried out at all, a large amount of manpower and financial resources can be input, the full-automatic equipment can be developed for operation, and accurate positioning is carried out by assisting with CCD (charge coupled device), but when the order quantity is not large, the cost is high, and the maintenance is often difficult. The utility model provides the following technical scheme: A jig for laminating a film inside a product, comprising: the plastic film sticking machine comprises a base, wherein a wedge-shaped push rod structure is fixedly arranged on one side of a vertical plate of the base, a product anti-shape positioning mechanism is arranged on the wedge-shaped push rod structure in an inserted mode, an injection molding piece needing an internal film sticking is fixedly inserted on the product anti-shape positioning mechanism, a protective film positioning hole aligned with a film sticking area inside the injection molding piece is formed in the product anti-shape positioning mechanism, a film sticking push plate structure is longitudinally arranged in the protective film positioning hole in a sliding mode, and a protective film body is arranged on the upper surface of the film sticking push plate structure. In one possible design, one side of the base vertical plate is fixedly provided with four guide posts in a rectangular array with the wedge-shaped push rod structure as a center, and the side plate of the product shape-preventing positioning mechanism is provided with guide sleeve holes for the corresponding guide posts to penetrate. In one possible design, the guide post is provided with a spring. In one possible design, the pad pasting push plate structure is a wedge block used in cooperation with a wedge push rod structure. In one possible design, one side of the protective film body is tacky. In one possible design, the film-pushing plate structure includes a silica gel base film.
