FIG. 2 is a diagram illustrating a configuration of a conventional example that is generally used, and FIG. 3 is a detailed diagram illustrating the main part of FIG.
As shown in FIG. 2, one of the basic operations of the handler device is to take out an IC device 2 contained in a pocket 1A installed at a certain position and move it into a pocket 1B installed at another position. It is.

  For holding the device 2, as shown in FIG. 3, a suction cup-like suction pad 31 is pressed against the upper surface of the device 2, and the air flow formed through the inside of the pickup body 32 to which the suction pad 31 is attached is formed. A method of sucking up with the negative pressure generated in the vacuum system 5 through the path 4 is often used.

Such an apparatus has the following problems.
At this time, the dust 6 away from the surface of the device is also sucked up by the negative pressure and enters the air flow path 4. The dust 6 that has entered may remain in the air flow path 4 in the pickup 3 or may travel to the vacuum system 5. For this reason, there is a disadvantage that causes the air flow path 4 and the vacuum system 5 to be clogged.

  Further, by returning the air flow path 4 to the atmospheric pressure, the device 2 can be separated at the pocket position of the transfer destination. If the dust 6 enters the pocket of the transfer destination and the device 2 does not enter the pocket correctly, or if it enters the device socket portion 7 that requires fine electrical contact, There were drawbacks that caused poor contact.

An object of the present invention is to solve the above-described problems and to provide a handler device that can prevent contamination.
More specifically, the defect that the vacuum path is clogged with foreign matter adsorbed from the surface of the device is improved, the defect that the foreign matter enters the transfer destination pocket and causes the device to climb, and the foreign matter reaches the IC socket. It is an object of the present invention to provide a handler device that can be carried and can improve the defect that causes poor contact.

  In addition, by adopting a configuration in which the pressure air application means is switched immediately before the vacuum system, even if the foreign material reaches the inlet of the vacuum system, the foreign material can be forcibly discharged, so that a handler device that does not cause clogging of the vacuum path can be obtained. .

  Furthermore, since the foreign matter is forcibly discharged into the foreign matter suction nozzle, the foreign matter will not fall on the device again after a certain amount of time has passed, so the foreign matter that has been a problem in the past is not transferred to the destination. It is possible to obtain a handler device that can enter a pocket and eliminate a defect that causes a device to not enter the pocket correctly or a device socket portion that requires fine electrical contact to cause contact failure.

  A handler device that reliably collects foreign matter is provided because one end of the pickup is arranged opposite to each other during operation of the pressure air application means, and a foreign matter suction nozzle is provided to introduce the pressurized air applied to the air flow path. Is obtained.

According to claim 2 of the present invention, there are the following effects.
Since the air compressor is used as the pressure air application means, a handler device capable of applying strong and reliable pressure air can be obtained.

According to claim 3 of the present invention, there are the following effects.
Since an air cylinder is used as the pressure air application means, a handler device capable of simple pressure air application is obtained.

According to claim 4 of the present invention, there are the following effects.
Since the foreign matter inflow nozzle is used as the foreign matter collecting means, a handler device that can easily collect foreign matter is obtained.
