Screening device

Abstract

The invention relates to a screening device. The screening device comprises a discharge unit, a turnover unit and a pickup unit, and further comprises a recognition unit. The obverse side and the reverse side of a material can be accurately judged through the recognition unit, the recognition speed is high, recognition is precise, and thus the problem of low artificial recognition process efficiency is solved. In the artificial recognition process, problems such as visual fatigue and wrong judgment are prone to occurring, obverse side and the reverse side recognition errors generated by artificial recognition can be effectively avoided through the recognition unit, and the percent of pass of products in the subsequent product assembly process is further guaranteed.

Description

technical field [0001] The invention relates to a screening device, in particular to a vibration screening device for a light-shielding spacer. Background technique [0002] As one of the important parts that block light in the mobile phone lens, the light-shielding spacer is showing a trend of thinning and has requirements for positive and negative directions. At present, the minimum thickness of the light-shielding spacers that have been used in mass production is as thin as 0.012mm. Under the current technological conditions, the mass assembly of such ultra-thin light-shielding spacers can only be done manually, or the light-shielding spacers are manually placed by personnel. Put it on the light-shielding spacer fixture, and then take out the light-shielding spacer by the manipulator and assemble it into other parts. In the context of mass production, this method of operation has low efficiency of manual operation and low production capacity of products. At the same tim...

Problems solved by technology

At present, the minimum thickness of the light-shielding spacers that have been used in mass production is as thin as 0.012mm. Under the current technological conditions, the mass assembly of this ultra-thin light-shielding spacers can only be done manually, or the light-shielding spacers are manually placed by personnel. Put it on the light-shielding spacer fixture, and then take out the light-shielding spacer by the manipulator and assemble it into other parts

In the context of mass production, this method of operation has low efficiency of manual operation and low production capacity of products

At the same time, in the process of manual operation, the light-shielding spacers are prone to bending, scratching and other poor appearance, and the scrap rate is high

[0003] In the process of manual operation, due to uncontrollable factors such as fatigue and misjudgment of the naked eye, problems such as wrong recognition of the front and back of the light-shielding spacer, reverse installation, over-installation, and missing installation are prone to occur, resulting in the scrapping of the entire set of lenses

Due to strict requirements on the proficiency of operators, the labor cost is also high

[0004] For the above problems, no effective solution has been proposed
