Abstract
The utility model relates to an air classifier. The air classifier comprises a material feeding hole, a blowing cylinder and a material accepting hopper. Two buffer slopes are arranged on the inner wall of the material feeding hole; a layer of soft cushion is adhered to the inner wall of the material accepting hopper; 3-5 discharge holes are arranged at the lower end of the material collection hopper; and the material openings of the material discharge holes are gradually reduced from right to left. With adoption of the structure provided by the utility model, the elements can be better classified by the air classifier and the semiconductor elements can be better protected during a classification process. The air classifier is simple in structure and is used for improving the work efficiency and reducing the labor intensity.
Description
Technical field:
The utility model relates to the equipment that a kind of semiconductor element is selected, and just relates to a kind of winnowing machine specifically.
Background technology:
Owing to use machine cuts; Exist the situation of appearance not of uniform size after the semiconductor element cutting; These elements mix the quality that the processing semiconductor device influences finished semiconductor; In semiconductor fabrication processes, also influence working (machining) efficiency,, classify according to size so need carry out primary election to semiconductor element.At present,, still can not classify to semiconductor element preferably, and in the process of selection by winnowing, fail well to protect semiconductor element though there has been the winnowing machine that is used for selecting element.
The utility model content:
The utility model provides a kind of easy to use, simple in structure in order to overcome above deficiency, can automatic winnowing machine according to magnitude classification.
The utility model is to realize through following technical scheme: a kind of winnowing machine comprises that inwall has two sloping charging apertures of buffering, Blowing drum; Receiving hopper; Inwall at receiving hopper has one deck cushion, is provided with 3 to 5 discharging openings in the lower end of receiving hopper, and discharging opening expects that from right to left mouth reduces gradually.
The utility model compared with prior art has the following advantages: owing to adopted said structure; Make such winnowing machine better classify to element; And can in the process of selecting, well protect semiconductor element; This winnowing machine is simple in structure, has improved operating efficiency and has reduced labour intensity.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the utility model charging aperture.
The specific embodiment:
In order to deepen understanding, will combine accompanying drawing that the utility model is done further to detail below to the utility model:
Like Fig. 1,2 is shown, and the utility model is a kind of winnowing machine, comprises charging aperture (1), Blowing drum (2), and receiving hopper (3) is characterized in that: said charging aperture (1) inwall has buffering slope (6) and buffering slope (7),
Inwall at said receiving hopper has one deck cushion (4), is provided with 3 to 5 discharging openings (5) in the lower end of said receiving hopper (3), and said discharging opening (5) expects that from right to left mouth reduces gradually.
This equipment is to be utilized under the effect of wind, and the stressed difference of particle drops on that the principle of diverse location processes.When semiconductor element when charging aperture slips into; When Blowing drum blows afloat element; Because inwall is provided with one deck cushion, element can not strike inwall and cause damage, and Blowing drum just blows to discharging opening far away with smaller and light element; And bigger and heavier element has just dropped on the discharging opening on the right, so just can well select element according to size.
The utility model is simple in structure, and is easy to use, can automatically the element of different sizes be classified, and improved production efficiency and reduced labour intensity.
Claims (3)
1. a winnowing machine comprises charging aperture (1), Blowing drum (2), and receiving hopper (3) is characterized in that: the inwall of said receiving hopper is provided with 3 to 5 discharging openings (5) with one deck cushion (4) in the lower end of said receiving hopper (3).
2. according to the said a kind of winnowing machine of claim 1, it is characterized in that: said charging aperture (1) inwall has buffering slope (6) and buffering slope (7).
3. according to the said a kind of winnowing machine of claim 1, it is characterized in that: said discharging opening (5) expects that from right to left mouth reduces gradually.
