Description

  The present invention relates to a collection device for an LED package inspection / distribution device, and more particularly, from a storage table that inspects manufactured LED packages and sorts them by type and stores the LED packages for each distribution. The present invention relates to a collection device for an LED package inspection / distribution device developed so that only LED packages sorted by distribution can be easily collected.

  A light emitting diode (LED), that is, a light emitting element, converts electricity into light, and has smaller characteristics, longer life characteristics, and faster response characteristics than conventional light sources. It is widely used in various fields such as display devices of various types, display lamps of various electronic devices such as light sources for optical communication, numeric display devices, card readers of computers, and backlights.

  Recent developments in production technology and the diversification of types are striking, and as a result, this type of light-emitting device is used in all fields, from general household lighting to automobile headlights and flashlights. LED is adopted.

  This type of LED is largely manufactured through an epi process, a chip process, and a package process, and the manufactured LED is subjected to a process of confirming its performance and allocating.

  Here, the LED has a structure in which different kinds of semiconductors are PN-junctioned, and the energy of electrons is directly converted into light energy to cause light emission. In the process in which the holes are recombined at the junction beyond the band gap, energy corresponding to the band gap is emitted and light is emitted.

  At this time, the emission color is determined by the band gap between the semiconductors to be joined, and when this is used well, colors such as blue, green, and white can be adjusted as desired.

  On the contrary, when manufacturing an LED, there is a possibility that the characteristics of the LED may be different depending on the band gap. Therefore, no matter how accurately the LED is manufactured, a process of distributing the LED after manufacturing is required.

  FIG. 15 is a plan view showing a conventional LED package distribution inspection apparatus, and FIG. 16 is a side view showing the conventional LED package distribution inspection apparatus. Referring to the drawing, the conventional LED package distribution inspection apparatus has a disk shape, and when a large number of manufactured LED packages are inserted, the LED supply unit moves the LED package to one side by vibration. 2, a transport device 3 for sequentially transporting LED packages moved to one side of the LED supply unit 2 in a certain direction, and the other one connected to the LED supply unit 2 of the transport rail 1 When one fixed block 41 approaches the lower end of the integrating sphere 43 and the rotary table 42 in which a large number of fixed blocks 41 into which one LED package is inserted and aligned are arranged on the upper surface adjacent to the tip. An illuminating unit 44 that irradiates light to the integrating sphere 43 through the LED package attached to the fixed block 41 from the lower part of the rotary table 42; The LED inspection part 4 which has the 1st picker 45 which transfers the LED package aligned in the conveying apparatus 3 to the fixed block 41 of the said turntable 42 adjacent, and the LED inspection part 4 on the upper surface adjacent to it Is a sorting rotary table 52 in which an LED insertion hole 51 penetrated in the lower part so that a large number of LED packages can be inserted is formed, and when the LED package inspected by the LED inspection unit 4 is lifted and reaches a predetermined position, When the sorting rotary table 52 rotates and one LED insertion hole 51 is positioned in the vertically lower part, the LED sorting unit 5 having a second picker 53 for dropping the LED package into the LED insertion hole 51, and the shaking And a collection device 9 having a collection table 91 for collecting the LED packages distributed on the minute rotation table 52.

  At this time, since the collection table 91 is formed in a cylindrical shape like the sorting rotation table 52 and has a large number of LED collection holes on the upper surface, the LED packages are stacked for each sorting inside. Although it is easy to store, the present situation is that there is no automated device for taking out (ie, collecting) these by sorting.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide LED package inspection distribution that allows an operator to easily and automatically discharge LED packages distributed to a collection table according to desired grades. A collection device for the apparatus is provided.

  Another object of the present invention is to provide a recovery device for an LED package inspection and distribution device that can easily discharge LED packages distributed to the LED recovery holes of the recovery table.

  In order to achieve the above object, the present invention transfers a large number of LED packages from the LED supply unit to the LED inspection unit by a transfer device, and distributes the inspected LED packages to the LED distribution unit by grade. In the collection device for the LED package inspection and distribution device for collecting the LED package, the collection device is fitted with the LED packages according to the grades distributed in the LED distribution unit 5, and an openable and closable door is formed on the bottom surface. Rotation is performed by a collection table having a columnar shape by a number of collection pipes arranged in a row, and a plurality of collection pipes arranged in a row, and a motor with a rotating shaft standing upward from the bottom of the collection table A rotating frame that is attached to the upper surface of the rotating frame and vertically below a plurality of recovery pipes arranged in a row. An LED package that falls on the upper surface that is formed and opened is stored, and a bottom surface of the first recovery box that can be opened and closed is attached to the upper surface of the rotating frame so that the first recovery box is opened. One or more door opening / closing means for opening and closing the opening / closing door when positioned at the lower part of the collecting pipe, and an LED package that falls when the first collecting box reaches a predetermined position and the bottom surface is opened And a recovery stage having at least one or more second recovery boxes formed so that the LED package 1 can be taken out by a pull-out type.

  Also, in the collection device for the LED package inspection and distribution device according to the present invention, the opening and closing door of the collection pipe is formed with a first hinge that is offset in one rotation direction on the collection table, and the first hinge. A torsion spring that acts as an elastic restoring force in the direction in which the opening and closing door is closed, and an opening and closing protrusion that is attached to the opening and closing door and hangs down from the first hinge. A first cylinder attached to the rotating frame; a lifting member that is moved up and down by the first cylinder; and a vertically extending from one end of the lifting member to pressurize the opening and closing protrusion by rotating the recovery table. And a cam member that opens the door.
