Abstract
A pre-press head may be operated by an operating method. The pre-press head includes an adsorption unit and a control unit. The adsorption unit includes at least two vacuum adsorption structures each including a gas path and at least one gas hole communicated with the gas path. The control unit is configured to control, according to a size of a to-be-adsorbed object, formation of vacuum environment of each vacuum adsorption structure. The adsorption unit is configured to adsorb the to-be-adsorbed object under the control of the control unit. The solution provided by the application adjusts adsorption functions of the vacuum adsorption structures according to a size of a to-be-adsorbed circuit board, so that the pre-press head can be applicable to circuit boards having different sizes.
