Vibrator screening device

Abstract

The invention discloses a vibrator screening device. The vibrator screening device comprises a machine frame, rotating shafts, a vibrating feeding disc and a motor driving device, the vibrating feeding disc is arranged at one end of the machine frame, the two rotating shafts are obliquely arranged on the machine frame side by side, the two rotating shafts are driven by the motor driving device torotate synchronously and oppositely, a discharging gap for allowing vibrators to fall is formed between the two rotating shafts, the end, close to the vibrating feeding disc, of the discharging gap isa front end, the end, far away from the vibrating feeding disc, of the discharging gap is a rear end, the width size of the discharging gap from the front end to the rear end is gradually increased,a feeding pipe is connected to a discharging port of the vibrating feeding disc, the outlet end of the feeding pipe is located above the front end of the discharging gap, a material receiving plate isfixed on the machine frame and below the discharging gap, a plurality of separation plates are arranged on the upper portion of the material receiving plate in the length direction of the material receiving plate at intervals, and a material falling channel is formed between every two adjacent separation plates. By using the screening device, the screening accuracy of the vibrators is high, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to a vibrator screening device, which belongs to equipment for vibrator production. Background technique [0002] With the development of social economy, mobile phones have been applied to become an indispensable tool in people's daily life by virtue of their advantages of mobile communication and convenience. In order to prevent missed calls or enhance reminders in noisy environments, mobile phones are often equipped with a vibration function, which can prompt calls or text messages in time through the vibration of the mobile phone. The vibration of the mobile phone is realized by the built-in vibration motor of the mobile phone. The vibrator is the core component of the vibration motor of the mobile phone. The vibrator is usually produced by the powder compaction forming process, that is, the tungsten-based alloy powder is put into the mold and formed into a green compact under a certain pressure, and then the pressed The blank...

AI Technical Summary

Problems solved by technology

After the mobile phone vibrator is manufactured, it needs to be classified according to the thickness and size. Most of the existing methods are manually inspected and classified one by one, but the production efficiency is low.
