Abstract
The utility model discloses an improved structure of a centrifugal precipitation machine. The centrifugal precipitation machine comprises a revolving drum, wherein the axis of the revolving drum is horizontally arranged, a plurality of axial convex ridges are arranged on the inner wall of the revolving drum, at least one side edge of each convex ridge is provided with an inwards sunken fixing groove, the fixing grooves oppositely formed between the two adjacent convex ridges are used for clamping a platy LED (Light Emitting Diode) retainer plate, and after the LED retainer plate is put in the fixing grooves of the revolving drum, and the distance between the outer edge of the fixing groove and each LED on the LED retainer plate is longer than the distance between each LED on the LED retainer plate. When the distance between the outer edge of the fixing groove and each LED on the LED retainer plate is relatively long, the revolving drum rotating at a high speed does not cause the adhesion of fluorescent glue to the outer edges of the fixing grooves due to swaying, i.e., the fluorescent glue does not break away from the LEDs, and therefore, on the one hand, the revolting drum of the centrifugal precipitation machine is prevented from being polluted due to glue adhesion, and on the other hand, the florescent glue is prevented from being absorbed away to cause the poor gluing of the LEDs on the edge, thus the production quality of the LEDs is greatly improved.
Description
Technical field
The utility model relates to a kind of structure-improved of centrifugal precipitation mechanism.
Background technology
In the encapsulation process of LED, much encapsulating enterprise is all directly to enter baking after a glue, easily causes the fluorescent material inequality, affects the LED quality, and on chip set, is prone to more fluorescent glue dead angle, makes the photon stream of the chip sides 10%-20% that fails to keep an appointment.In order to improve this bad phenomenon, up-to-date way is first to carry out centrifugation after LED point fluorescent glue, toast again, yet, when centrifugal precipitation mechanism carries out centrifugation technique, need to be with the about speed High Rotation Speed of 2000 rev/mins, and fluorescent glue now also toasts, but be in flow regime, therefore, in the process of centrifugal precipitation mechanism High Rotation Speed, often can cause the upper loose fluorescent glue of LED to be dumped into LED flitch and centrifugal precipitation mechanism holddown groove gap space, not only make centrifugal precipitation mechanism be stained with glue stain, and make LED glue bad, affect the LED quality.
The utility model content
The purpose of this utility model is to provide a kind of structure-improved of centrifugal precipitation mechanism so that in the centrifugation process without being stained with glue and LED glue is bad.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The structure-improved of centrifugal precipitation mechanism, this centrifugal precipitation mechanism comprises rotary drum, the axle center of described rotary drum is horizontally disposed with, the inwall of this rotary drum is provided with some axial fins, at least one side of fin has the holddown groove caved inward, the holddown groove be oppositely arranged between two adjacent fins is be used to blocking the LED flitch of film releasing shape, and after LED flitch card was put into the holddown groove of described rotary drum, the holddown groove outer was greater than the spacing of each LED on the LED flitch to the distance of LED material onboard led.
The fin of described drum inner wall is for evenly spaced, and the dual-side of fin all has the holddown groove caved inward.This makes the LED flitch quantity that can put in rotary drum maximum, has improved the efficiency of centrifugation.
The beneficial effects of the utility model are: when the holddown groove outer is larger to the distance of LED material onboard led, the rotary drum of high speed rotating can not cause fluorescent glue to adhere to the holddown groove outer because of whipping, be that fluorescent glue can not break away from LED, therefore, can not cause the rotary drum of centrifugal precipitation mechanism to pollute because being stained with glue on the one hand, also can not cause on the other hand the LED at edge bad because fluorescent glue is sucked away product glue, greatly improve the production quality of LED.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the overall structure schematic diagram of centrifugal precipitation mechanism;
Fig. 2 is the partial enlarged drawing of A section in Fig. 1.
The specific embodiment
With reference to figure 1 and Fig. 2, the structure-improved of centrifugal precipitation mechanism, this centrifugal precipitation mechanism comprises frame 100, rotary drum 200, drive unit, control system, control panel 300 and velocity sensor 400, the axle center of described rotary drum 200 is horizontally disposed with, the inwall of this rotary drum 200 is provided with some axial fins 210, at least one side of fin 210 has the holddown groove 211 caved inward, the holddown groove 211 be oppositely arranged between two adjacent fins 210 is be used to blocking the LED flitch 500 of film releasing shape, after LED flitch 500 cards are put into the holddown groove 211 of described rotary drum 200, holddown groove 211 outer 211a are greater than the spacing of each LED510 on LED flitch 500 to the distance of LED510 on LED flitch 500.When the holddown groove outer is larger to the distance of LED material onboard led, the rotary drum of high speed rotating can not cause fluorescent glue to adhere to the holddown groove outer because of whipping, be that fluorescent glue can not break away from LED, therefore, can not cause the rotary drum of centrifugal precipitation mechanism to pollute because being stained with glue on the one hand, also can not cause on the other hand the LED at edge bad because fluorescent glue is sucked away product glue, greatly improve the production quality of LED.A kind of preferred mode: the fin 210 of described rotary drum 200 inwalls is for evenly spaced, and the dual-side of fin 210 all has the holddown groove 211 caved inward.This makes LED flitch 500 quantity that can put in rotary drum 200 maximum, has improved the efficiency of centrifugation.
Above embodiment just is explanation rather than restriction the utility model, therefore all equivalences of doing according to the described method of the utility model patent claim change or modify, is included in the utility model patent claim.
