Abstract

The vacuum fixture includes base board, chuck unit and support pins, the base board is provided with screw holes, the chuck unit includes chuck and air pipe connected to the chuck, and each of the support pins has head for supporting workpiece. Both the chuck unit and the support pins are provided with threads, so that the chuck unit and the support pins may be installed onto the base board via the screw holes. The height of the the chuck unit and the support pins relative to the base board may be regulated separately. After some workpiece is supported with the support pins, vacuum is applied to the chuck unit and the workpiece may be vacuum fixed.

Description

【Technical field】 [0001] The invention relates to a fixture for holding workpieces and a method for using the same, in particular to a vacuum fixture for absorbing workpieces with a suction cup and a method for using the same. 【technical background】 [0002] As the products of the 3C industry become lighter and thinner, if the traditional fixture is used to clamp and position the thinner and thinner products, the processing difficulty will become more and more difficult. Specifically, the traditional fixture is used to clamp and position the workpiece When it is used, it is easy to warp and deform the workpiece, and even cause damage. [0003] In order to solve the problems existing in the above-mentioned traditional clamps, the industry uses vacuum clamps to replace the traditional clamps to fix these thin parts. Although the term "vacuum" is conventionally used here, the reality is that the ideal vacuum is never achieved. A more common situation is a vacuum with an avera...
