The seventh figure is a schematic view of the electronic component being ejected from the collection box in the embodiment of the present invention.

Referring to the first figure, the component blanking buffering method of the present invention is described by way of an apparatus which is a blanking collection device used in an electronic component sorting machine, including: a plurality of collections. a box 1 and a plurality of guiding members 2; the plurality of collecting boxes 1 are arranged in a matrix in a carrier 3; the plurality of guiding members 2 are each a tubular body and are arranged in a matrix on a loading table 4 Each of the guiding members 2 respectively corresponds to a collecting box 1 and is located above the corresponding collecting box 1 respectively.

Referring to the second and third figures, the collecting box 1 is provided with a cushioning member 5, which is disposed at the opening 11 of the near collecting box 1, and is made of soft flexible material such as silicone or rubber. The two sides of the opening 11 of the collecting box 1 are formed with four mutually symmetric wall faces 12, and a pair of mutually parallel first and second wall faces 121 and 122 are respectively provided with pivots. The hole 125 is pivoted by the two pivots 51 so that the cushioning member 5 can be rotated relative to the collecting box 1; the cushioning member 5 forms a buffering surface 52 on one side of the upper surface in the direction of the opening 11, the buffering surface 52 being the axis of the pivot 51 As a dividing line, L is divided into a first buffering surface 521 which is different in area from the third wall surface 123 perpendicular to the wall surfaces 121 and 122 of the pivot hole 125, and is perpendicular to the wall surfaces 121 and 122 of the pivot hole 125. a second buffer surface 522 extending in the direction of the fourth wall surface 124, wherein the first buffer surface 521 is larger than the second buffer surface 522, and on the other lower surface side of the upper surface side buffer surface 52 of the buffer member 5, The axis L is oppositely extended to protrude from a blocking member 53 which is approximately perpendicular to the buffer surface 52; the pivot hole 125 is disposed Against the second buffer surface toward the fourth wall 124 522, and the stopper 53 is greater than the length of the contact member 125 to the fourth wall surface of the pivot hole 124 of the pitch, And the length of the second buffer surface 522 is smaller than the distance between the pivot 51 and the fourth wall 124. Therefore, the buffer member 5 will generate a gravity under the influence of the gravity of the first buffer surface 521 and the second buffer surface 522. The angle of the angle is such that the first buffer surface 521 is lower than the second buffer surface 522, and the retaining member 53 is locked against the fourth wall surface 124 to maintain the normal state of the positioning; and the end of the first buffer surface 522 is A drop inlet 13 is formed with a space remaining between the third wall 123 facing it.

Referring to the fourth, fifth and sixth figures, one end of the guiding member 2 is fixed on the loading platform 4, and the other end is connected with the conduit 6. The circumference of the tubular body of the guiding member 2 is provided with a plurality of venting holes 21; the guiding member 2 is disposed in the through hole 41 of the stage 4, and has an annular flange-shaped fastening portion 42 at the end thereof, which is embedded in the annular recess 43 at the bottom end of the through hole 41 of the stage 4, and is additionally provided. A buckle ring 44 is fastened to the periphery of the guide member 2 above the loading platform 4 at an annular recessed buckle groove 45 to fix the guide member 2 to the carrier 4.

Referring to FIG. 6 , the electronic component W is transported to the transport flow path A between the conduit 6 through which the electronic component W is movable and through which the gas is passed, and the collection box 1 , including the vent hole of the guide member 2 . The first conveying flow path A1 of the front air supply section 21 and the second conveying flow path A2 of the decompression section of the inner side of the collecting box 1 after the exhaust hole 21 of the guiding member 2 are passed through the first conveying flow path A1; There is gas to push the electronic component W, and the gas is dissipated to the outside of the guide member 2 at the vent hole 21 of the guide member 2, and the gas is decompressed to reduce the pushing of the electronic component W, so that the electronic component W can fall by its gravity.

In an embodiment of the present invention, the pivotable cushioning member 5 is disposed on the conveying flow path A of the gas conveying electronic component W to the collecting box 1, and is located in the collecting box 1 and is decompressed after being located in the collecting box 1. In the second transport flow path A2 of the segment; when the electronic component W is pushed by the gas in the first transport flow path A1 of the air supply section, it flows through the exhaust hole 21 At the time, since the gas is dissipated to the outside of the guide member 2 through the vent hole 21, the falling speed of the electronic component W in the second conveying flow path A2 is slowed down, and falls to the cushioning member 5 and the conveying flow. When the road A maintains the angled inclined buffer surface 52, the first buffer surface 521 of the cushioning member 5 made of soft flexible material is touched at a relatively gentle first buffering speed, and the falling speed of the electronic component W is again slowed down. The second buffering speed, which is further slowed down, is naturally dropped by the landing 13 to the bottom of the collecting box 1 to be collected.

Referring to the seventh figure, if the electronic component W in the collection box 1 is to be taken out, it is only necessary to pour the collection box 1 downward so that the opening 11 faces downward, since the cushioning member 5 can pivot the pivot 51, and The length of the second buffer surface 522 is smaller than the distance between the pivot 51 and the fourth wall 124. Therefore, the buffer member 5 can be rotated to extend downwardly from the first buffer surface 521, so that the opening 11 is opened and the opening 11 is protruded. The state makes the electronic component W easy to pour out from the collecting box 1.

The method and apparatus provided by the embodiments of the present invention enable the electronic component W to obtain a first buffering speed when the gas that drives the electronic component W moves out of the exhaust hole 21 when entering the second conveying flow path A2, and The buffering member 5 is disposed in the second conveying flow path A2, so that the electronic component W is first blocked by the buffer surface 52 of the buffering member 5 before falling to the bottom of the collecting box 1, and once again obtains a gentle second buffering speed to slow down the electronic components. The falling speed of W falls to the bottom of the collecting box 1 to prevent the electronic component W from falling directly to the bottom of the collecting box 1; and when the electronic component W is dumped from the collecting box 1, the cushioning member 5 can be compared with the first buffer surface area. The large pivoting position due to gravity changes the position so that the electronic component W can be poured out smoothly.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are Still belong to the invention Within the scope of the benefit.
