It is advantageous.

In addition, in the configuration in which the suction member 23 is installed on the turntable 21, since the circumference of the electronic component may be exposed to the outside while the electronic component is absorbed by the suction member 23, the electrode may be exposed to the side of the electronic component. Even when disposed in the above, there is an advantage that the probe pin connected to the power source can be easily contacted with the electrode of the electronic component.

On the other hand, it is preferable that the width Ws of the adsorption part 231 is smaller than the width Wp of the electronic component adsorbed by the adsorption part 231. In this case, even when the electrode is disposed on the lower surface of the electronic component, there is an advantage that the probe pin connected to the power source can be easily contacted with the electrode of the electronic component through the area A open to the lower side of the electronic component. . In addition, a portion of the lower surface of the electronic component that is not adsorbed by the adsorption unit 231 may be exposed to the outside through the open area A, and air may be injected toward the exposed portion. In addition, by spraying air on the lower surface of the electronic component, there is an advantage that the electronic component can be easily separated from the adsorption member (23).

In addition, it is preferable that an inclined surface 234 is formed around the adsorption part 231 to guide the air injected by the air injection mechanism 24 toward the electronic component adsorbed by the adsorption part 231. Therefore, the injected air may be guided to the inclined surface 234 and collide with a portion of the lower surface of the electronic component that is not adsorbed by the adsorption portion 231 through the open area A, so that the electronic component may absorb the suction member 23. It can be easily separated from.

Therefore, the force of the injected air can be appropriately applied to the electronic component, and thus, the process of detaching the electronic component from the suction member 23 can be performed smoothly.

The flow path 241 and the discharge port 242 are provided in plurality so as to correspond to the plurality of suction members 23. Therefore, the electronic component can be separated from the adsorption member 23 and discharged through a simple operation in which the arc-shaped flow path member 243 is installed to cover the plurality of adsorption members 23.

As shown in FIG. 4, the flow path 241 is formed to be inclined from the lower side to the upper side of the electronic component along the flow direction of the air so that the air passing through the passage 241 flows toward the lower surface of the electronic component.

Therefore, since the air passing through the flow path 241 may flow to a portion of the lower surface of the electronic component that is not adsorbed by the adsorption unit 231, the electronic component may be easily separated from the adsorption member 23.

The inspection unit 30 serves to inspect the characteristics of the electronic component moving in the circumferential direction of the turntable 21 by the intermittent rotation of the turntable 21.

For example, when the electronic component is a light emitting diode, the inspection unit 30 connects power to the light emitting diodes and then supplies power to the first inspection unit 31 and the light emitting diodes, which measure electrical characteristics such as whether the light emitting diodes are energized.
