Abstract

The invention relates to a classifying and sorting method of an electronic component. The classifying and sorting method is characterized in that the method comprises the following steps: firstly embedding a plastic air pipe capable of being replaced easily into an inner wall of a blowing head, then directly connecting the plastic air pipe to a separating head; embedding a protecting sleeve made of silicon gel material to the inner wall of the separating head, wherein a protecting sleeve is cut with a slot for facilitating the detection of a sensor; meanwhile, the outer wall of the silicon gel protecting sleeve is provided with hard spare parts in order to ensure that the mis-judgment through the sensor cannot be made when the separating head is swayed at high speed; and the inner wall of each falling opening of a falling platform is sleeved with the silicon gel protecting sleeve. The plastic air pipe is directly extended to the positive upper part of a material cylinder from each falling opening; the air pipe is fixed by upper and lower steel wire gauzes, so that the steel wire gauzes are perpendicular to the cylinder opening; each cylinder opening is sleeved with the silicon gel protecting sleeve; for the protecting sleeve is designed with a buffer slope opening, products cannot directly fall off as the silicon gel absorbs a part of gravity of the product firstly, and therefore the product is protected.

Description

A kind of category sorting method of electronic devices and components

Technical field

The present invention relates to a kind of product protection method, further relate to the guard method of a kind of electronic devices and components in category sorting process.

Background technology

Electronic component (as LED), because of it outstanding performance possessing, has obtained the general popularization that is applied in every field in recent years.After LED has manufactured, or use buy after through often detecting its every photoelectric parameter, and classify according to testing result and requirement.At present, electronic component enters in corresponding BIN after test, is generally blown into barotropic gas, in this process, electronic component and the collision of blowing material tube wall and producing while falling into barrel, easily damage electronic component, causes the increase of electronic component fraction defective.

Summary of the invention

In view of above content, be necessary to provide a kind of damage of current electronic devices and components in category sorting process that solve, can effectively reduce the method for damage of product.

The invention provides a kind of category sorting method of electronic devices and components; it is characterized in that; the method comprises: first; blow stub bar inwall embed be easy to change plastic cement tracheae; then plastic cement tracheae directly accesses sub butt ends; sub butt ends inwall embeds protective sleeve, then all protective sleeves on inner wall sleeve of each blanking port of blanking platform.Last plastic cement tracheae by each blanking port directly extend to barrel directly over, tracheae is fixed by upper and lower two-layer steel wire, makes it perpendicular to barrel mouth, each barrel mouth all puts cushion collar.

Preferably, the Silicone Case that described sub butt ends inwall embeds cuts open a groove, convenient by the detection of sensor.

Preferably, the Silicone Case outer wall that described sub butt ends inwall embeds has rigid material part close-fitting, ensures that sub butt ends, in high speed swinging, can not cause the erroneous judgement by sensor.

Preferably, the cushion collar that described each barrel mouth all puts has designed buffering angle, makes a part of gravity of the first absorbing products of cushion collar and can directly not drop, thereby play the effect of protection product.

Preferably, described cushion collar be installed in can integrally rotated pedestal on, in the time of feeding, without cushion collar is removed one by one, only closed assembly need be opened, facilitate feeding.

The invention has the advantages that: the present invention has adopted and blown the embedded plastic cement tracheae of material pipe; sub butt ends inwall embeds protective sleeve and each barrel mouth all puts cushion collar; effectively reduce light-emitting component and entered the damage of process of barrel, reduced the fraction defective of product.

Detailed description of the invention

The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.As Fig. 2-Fig. 6; embed and be easy to the tracheae 1 of plastic cement material changed blowing stub bar 1 inwall; then plastic cement tracheae 1 directly accesses sub butt ends 3; sub butt ends 3 inwalls embed the protective sleeve 1 of silica gel material, and wherein protective sleeve 1 cuts open a groove, convenient by the detection of sensor 6; simultaneously; Silicone Case 4 outer walls have fitted component 5 close-fittings of rigid material part, ensure that sub butt ends 3, in high speed swinging, can not cause by the erroneous judgement of sensor 6.Then all protective sleeves 28 of silica gel material on inner wall sleeve of each blanking port of blanking platform 9.The tracheae 2 11 of plastic cement material by the each blanking port of blanking platform 9 directly extend to barrel 13 directly over, tracheae 2 11 is fixing by upper and lower two-layer steel wire 10, make it perpendicular to 13 mouthfuls of barrels, 13 mouthfuls of each barrels all put the cushion collar 12 of silica gel material, and this cushion collar 12 has designed buffering angle, make a part of gravity of the first absorbing products of silica gel and can directly not drop, thereby play the effect of protection product, simultaneously, the cushion collar of all silica gel materials is installed on rotatable pedestal 7, in the time of feeding without cushion collar is removed one by one, only closed assembly need be opened, facilitate feeding, enhance productivity.

Simple and easy variation and the equivalent transformation of such as doing by description of the present invention and graphic content the foregoing is only preferred embodiment of the present invention, non-ly therefore limit to the scope of the claims of the present invention, therefore all should be contained in the scope of the claims of the present invention.
