Embodiment Construction

[0014] In order to better understand the spirit of the present invention, it will be further described below in conjunction with some preferred embodiments of the present invention.

[0015] On a sorting machine for sorting electronic components, such as semiconductor packages, the visual inspection device usually includes a rotary table and a carrier table in a mother-in-law structure. The carrying platform is provided with a rotating space for the rotating shaft of the rotating platform to rotate at a high speed therein, and to maintain vacuum and airtight contact between the two. Since the bearing table is used to limit the rotation table in a way of stress compression, the rotation table and the bearing table need to be made of wear-resistant and hard materials, such as tungsten steel. However, this kind of material is usually expensive, highly brittle, and requires precise dimensions. Once deformed, it cannot be returned to its original size through mechanical processing,...

Abstract

The invention relates to a visual inspection device for a sorting machine. According to the visual inspection device for the sorting machine, a rotation platform is configured to drive four stations to be switched between a feeding / discharging device and a detection device, and a carrying platform is configured to limit a rotary shaft of the rotation platform to rotate in the rotation space of the rotation platform and makes the rotation space keep vacuum airtightness. The carrying platform further comprises a body, four sliding blocks and four springs. The body is provided with four sliding spaces distributed in a right-angle mode. The adjacent sliding blocks contact with each other. The sliding blocks are configured to slide in the corresponding sliding spaces and limited in the perpendicular directions through limit grooves of the sliding spaces. Each sliding block is provided with a rear end surface opposite to the rear wall of the corresponding sliding space and a front end surface opposite to the rear end surface, and the front end surface is in a shape of a 90-degree arc to make the four sliding blocks define the round rotation space jointly. The springs are configured to be respectively limited between the rear walls of the corresponding sliding spaces and the corresponding sliding blocks. The visual inspection device for the sorting machine has the advantages of being good in airtightness, low in cost, long in service life and the like.

Description

technical field [0001] The present invention relates to a visual inspection device, in particular to a visual inspection device for a sorting machine. Background technique [0002] The visual inspection device of the sorting machine generally includes a rotary table and a carrying platform that limits the rotary table to rotate thereon. When working, the motor drives the rotary table to rotate at a high speed in the bearing table, such as 400,000 revolutions per day and night. Due to the tolerances of the rotor of the motor, the coupling and other components, any rotating parts driven by the motor cannot be absolutely concentric when rotating, so the surface contact relative rotation structure of the rotating table and the bearing table has the disadvantage of being prone to wear and tear. However, if the visual inspection device has high requirements on air tightness, even slight wear and tear will result in unqualified vacuum requirements. For example, in the visual insp...
