Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、電子部品を吸着・離脱する装置に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to an apparatus for attracting and detaching electronic components.
従来は、電子部品を吸着するニトリル、シリコン系のゴ
ムパッドの材質にカーボンを含有させたり、電子部品を
吸着させる部分に、外部がら除電装置を設け、イオンを
吹き付たりして、電子部品に帯電する静電気の発生を防
いでいた。Conventionally, electronic components were charged by adding carbon to the material of the nitrile or silicon rubber pad that attracts electronic components, or by installing an external static eliminator in the area where electronic components are attracted and spraying ions. This prevented the generation of static electricity.
上記従来技術は、ニトリル・シリコン系のゴムパッドの
材質にカーボンを含有させ電子部品に帯電する静電気の
発生を防いでいたがパッドの使用条件等により電子部品
の帯電圧基準である±５０Ｖ以下を満足できないという
問題があった。The above conventional technology prevents the generation of static electricity that charges electronic components by incorporating carbon into the material of the nitrile/silicon rubber pad, but depending on the usage conditions of the pad, etc., it satisfies the charge voltage standard for electronic components of ±50V or less. The problem was that I couldn't do it.
本発明の目的は、電子部品の帯電圧基準の±５０Ｖ以下
を満足することにある。An object of the present invention is to satisfy the charging voltage standard for electronic components of ±50V or less.
上記目的を達成するために、本発明はゴムバットにリン

、ゴムパッドの柔軟性を維持するようにした。In order to achieve the above object, the present invention fits a ring-shaped metal pad into a rubber bat so that the metal pad makes contact with electronic components to suppress the generation of static electricity and maintain the flexibility of the rubber pad. I did it like that.
電子部品の静電気の帯電は、ゴムパッドの吸着・離脱動
作による摩擦と剥離により発生する。従来はゴムパッド
にカーボンを含有させ導電性及び硬度を増したが、使用
条件等により電子部品の帯電圧基準の±５０Ｖ以下を満
足できなかった。Static electricity charging of electronic components occurs due to friction and peeling caused by the adsorption/separation of rubber pads. Conventionally, rubber pads have been made to contain carbon to increase conductivity and hardness, but due to usage conditions, etc., it has not been possible to satisfy the charging voltage standard of ±50 V or less for electronic components.
以上のことにより、パッドの導電性、及び、硬度が電子

パッドとの併用によりパッドと電子部品の傾きを補正し
て吸着動作ができる。As described above, since the conductivity and hardness of the pad are related to the charging voltage of the electronic component, a metal that satisfies both the conductivity and hardness of the pad was formed into a ring shape and fitted into the conventional carbon-containing rubber pad. As a result, since the contact with the electronic component is a metal surface, the electrostatic charge voltage becomes ±50V or less. In addition, when used in combination with a rubber pad, the inclination between the pad and the electronic component can be corrected for suction operation.
以下、本発明の実施例を第１図、第２図により説明する

題がある。Embodiments of the present invention will be described below with reference to FIGS. 1 and 2. Conventional suction pads are made of nitrile, as shown in Figure 1.
It is composed only of a silicone rubber pad 2. Depending on usage conditions, there are problems with static electricity generation and short life due to high temperature contact.

しないため高温化での使用も可能となっている。The suction pad of the present invention is shown in FIG. The metal pad 1 is fitted into a conductive nitrile rubber pad 2 and fixed with a pad metal fitting 3. Further, the fitted state of the metal pad 1 is such that the conductive nitrile rubber pad 2 does not come into contact with the electronic component 4 (gap 5). Further, since the metal pad 1 is fitted into the flexible conductive nitrile rubber pad 2, it is possible to attract the electronic component 4 even if it is slightly tilted. Furthermore, since the conductive nitrile rubber pad 2 does not come into direct contact with the electronic component 4 for high temperature measurement due to the metal pad 1, use at high temperatures is also possible.
