High-precision stamping mechanism for computer screen anti-dazzling screen machining based on rapid positioning

Abstract

The invention discloses a high-precision stamping mechanism for computer screen anti-dazzling screen machining based on quick positioning, which comprises a machining platform and an upper stamping seat, a lower stamping seat is arranged in the middle of the top of the machining platform, and a positioning punching mechanism is arranged in the lower stamping seat. Each positioning punching mechanism comprises a sleeve, a second spring, an intelligent alarm system, a lower punching needle and an upper punching needle; through structural cooperation of the guiding and positioning assembly, when the anti-dazzling screen is placed, the anti-dazzling screen can be automatically guided to be flatly placed into the surface of the lower punching base, rapid positioning of the anti-dazzling screen is achieved, under the elastic lifting and extruding action of two sets of guiding frames and guiding wheels, one end of the anti-dazzling screen is limited, and the anti-dazzling screen can be conveniently and rapidly placed. As the anti-dazzling screen is embedded into the two sets of inclined guide grooves and the positioning clamping plates, the other end face of the anti-dazzling screen can be clamped and fixed, the fixing effect of the anti-dazzling screen in the horizontal state is effectively guaranteed, and the machining and stamping stability of the anti-dazzling screen is improved.

Description

technical field [0001] The invention relates to the technical field of stamping devices, in particular to a high-precision stamping mechanism for computer screen shading sheet processing based on rapid positioning. Background technique [0002] At present, in the optical lens, in order to eliminate stray light, a light-shielding sheet is often set between the display screen or the lens. The light-shielding sheet is usually formed by one-time stamping. The needle is formed by stamping process. During the stamping process, the upper punch is mainly used to punch the corresponding position of the material plate, so as to achieve the purpose of stamping process. [0003] When the current shading sheet is punched, it is first necessary to place the shading sheet on the platform, and make the punching part of the shading sheet correspond to the punching needle, and then manually operate the clamping structure to position the shading sheet before proceeding. Stamping work, the ope...

Problems solved by technology

[0003] When the current shading sheet is punched, it is first necessary to place the shading sheet on the platform, and make the punching part of the shading sheet correspond to the punching needle, and then manually operate the clamping structure to position the shading sheet before proceeding. Stamping work, the operation process is relatively cumbersome, and the manual positioning and adjustment of the shading sheet is prone to offset and misalignment, resulting in incomplete correspondence between the punching hole and the punching needle, reducing the accuracy and efficiency of the shading sheet stamping. In addition, during the stamping of the shading sheet , The stamping part of the shading sheet is often carried out in multiple groups at the same time. If the details of one group of punching heads are worn out, it may cause the shape of the single group of shading sheets to be processed and stamped to be incompletely symmetrical or uneven. Punching and forming, it is difficult for the operator to automatically detect and know, thereby increasing the waste products after product processing and forming, and reducing the pass rate of the production and processing of the shading sheet
