Embodiment Construction

[0008] In order to deepen understanding of the present invention, the present invention will be described in further detail below in conjunction with accompanying drawing:

[0009] Such as figure 1 , shown in 2, the present invention is a kind of winnowing machine, comprises feed inlet (1), blower (2), receiving hopper (3), is characterized in that: described feed inlet (1) inner wall has buffering slope (6) and buffer slope (7),

[0010] A layer of cushion (4) is attached to the inner wall of the material receiving port, and 3 to 5 discharge ports (5) are arranged at the lower end of the receiving hopper (3). Gradually decrease to the left.

[0011] This equipment is made of the principle that under the action of wind blowing, the particles fall on different positions under different forces. When the semiconductor element slides in from the feed port, when the blower blows up the element, since the inner wall is provided with a layer of cushion, the element will not hit th...

Abstract

The invention relates to a winnowing machine. The winnowing machine comprises a feed port, an air blowing barrel and a material receiving hopper, wherein two buffer slopes are arranged on the inner wall of the feed port; a layer of soft pad is adhered on the inner wall of the material receiving hole; 3 to 5 discharge ports are arranged on the lower end of the material receiving hopper; and the discharge ports are gradually reduced from right to left. With the abovementioned structure, the winnowing machine can classify elements better, and protect semiconductor elements better in the selecting process; moreover, the winnowing machine has a simple structure, improves the working efficiency and reduces the labour intensity.

Description

Technical field: [0001] The invention relates to a device for selecting semiconductor components, in particular to a wind separator. Background technique: [0002] Due to the use of mechanical cutting, there are different sizes of semiconductor components after cutting. These components are mixed together to process semiconductor devices, which affects the quality of semiconductor products and also affects the processing efficiency during semiconductor processing. Therefore, it is necessary to conduct primary selection of semiconductor components. Sort by size. At present, although there is a winnowing machine for selecting components, it is still unable to classify semiconductor components well, and the semiconductor components cannot be well protected during the winnowing process. Invention content: [0003] In order to overcome the above disadvantages, the present invention provides a winnowing machine that is easy to use, simple in structure, and can be automatically ...
