  FIG. 1 is a perspective view schematically showing a configuration of a packaging system for electronic components on which a component stacking device (3) according to an embodiment of the present invention is mounted.

  The electronic component packaging system (100) of the embodiment shown in FIG. 1 receives a large amount of electronic components that have been manufactured in individual units, detects defective products, and has good quality electronic components (non-defective products). This is a device that executes a function of loading only the selected electronic components on the tray in a correctly arranged posture.

  The electronic component packaging system (100) is controlled by a control unit such as a computer having control software, a central processing unit (CPU) manufactured on one semiconductor chip, and a printed circuit board having various semiconductor chips. By doing so, various components can be operated. The control of the operation of each component of the electronic component packaging system (100) described below is performed by the control unit.

  A first guide (102) extending in a direction parallel to the Y-axis is disposed on the substrate portion (101) of the electronic component packaging system (100). In the first guide (102), the component stacking device (3) is arranged to be movable along the first guide (102). The component stacking device (3) can move along the first guide (102) by power supplied from a drive unit (103) provided in the first guide (102).

  The component loading device (3) includes a loading plate (320) on which electronic components supplied from the component supply robot (107) are loaded. The component supply unit (108) has a function of temporarily storing a plurality of electronic components that have been manufactured. An operator may manually supply an electronic component to the component supply unit (108), and the electronic component may be supplied by a separate power supply device (robot).

  FIG. 2 is a perspective view showing an operating state of the electronic component packaging system of FIG.

  When the component supply robot (107) picks up the electronic component stored in the component supply unit (108) and supplies it to the loading plate (320) of the component loading device (3), the component loading device (3) receives the first guide ( 102) to the position of the first camera (110).

  The first camera (110) takes images of a plurality of electronic components placed on the surface of the stacking plate (320). The control unit of the electronic component packaging system (100) uses the captured image of the first camera (110) to position the X and Y axes of each of the plurality of electronic components and the rotated angle (θ). Can be calculated. The first camera (110) can move in the direction parallel to the X axis along the fourth guide (150).

  FIG. 3 is a perspective view showing another operation state of the electronic component packaging system of FIG.

Specifically, by moving the fourth camera (113) in one direction parallel to the X axis while moving the tray (171) along the third guide (140), the entire tray (171) is moved. You can take an image of your pocket.

  By synthesizing images taken by the fourth camera (113), a complete image of the electronic components inserted in the entire pocket of the tray (171) can be obtained, and the electronic components inserted in the pocket If there is a defective product with a poor loading state, an inspection result can be output to give a warning.

  In the electronic component packaging system (100) having the above-described configuration, the upper surface appearance inspection and the lower surface appearance inspection of the electronic component sucked by the nozzle (131) of the rotary head (130) are continuously performed during a series of processing steps. It can be done at high speed. Accordingly, the electronic component is transferred to the tray (171), and the appearance inspection of the upper surface and the lower surface of the electronic component is performed with high accuracy, thereby improving the speed and reliability of the electronic component packaging process.

  Further, after accurately recognizing the position of each electronic component from the image acquired from the first camera (110), the rotary head (130) can quickly adsorb each electronic component, The adsorbed rotary head (130) can move to the tray (171) after passing through the inspection process of the third camera (112) to quickly execute the component loading process.

  With the above-described configuration, the movement distance in one direction parallel to the X axis of the rotary head (130) is minimized, and components can be loaded (loaded) on the tray (171) at high speed, and electronic components can be packaged. The overall size of the system (100) can be minimized.
