Abstract

The invention discloses a solder ball size screening device and method, and relates to the field of solder ball screening. The solder ball size screening device comprises a funnel-shaped feeder, a ball rolling path adjuster is connected to the feeder through a pipeline, a vibration motor is arranged at an inlet of the ball rolling path adjuster, the output end of the ball rolling path adjuster isconnected with an optical glass track, the tail end of the optical glass track is connected with a positive electrostatic generator, and a qualified ball container is arranged below the positive electrostatic generator; and an industrial camera is arranged over the optical glass track, a telecentric lens is arranged on the industrial camera, a telecentric parallel light source is arranged under the optical glass track, the industrial camera is connected with a computer, the computer is further connected with a negative electrostatic generator, the negative electrostatic generator is located obliquely below the positive electrostatic generator, and a waste ball container is arranged below the negative electrostatic generator. According to the solder ball size screening device, only the solder balls need to be poured into the inlet, the solder balls automatically complete size and roundness measurement, and qualified products are screened out.

Description

technical field [0001] The invention relates to the field of tin ball screening, in particular to a tin ball size screening device and method. Background technique [0002] In the production of tin balls, the tin balls are continuously ejected from the nozzle holes and fall into the collection container. Because the tin liquid in the crucible continues to drop, the pressure of the nozzle holes gradually decreases. If no intervention is made at this time, the diameter of the tin balls will increase with the As the tin liquid drops and gradually decreases, it is necessary to adjust the air pressure in the crucible in real time according to the diameter of the tin balls, and the real-time measurement of the size of the produced tin balls becomes the key. It is advisable, if manual measurement is performed with a microscope, the measurement efficiency is low. [0003] Conventional sieve balls use precision sieves. A single 200mm diameter circular sieve costs 20,000 yuan per pie...
