Abstract

The invention discloses a false pressure head and an operating method thereof. The false pressure head comprises an adsorption unit and a control unit. The adsorption unit comprises at least two vacuum adsorption structures. Each vacuum adsorption structure comprises an air passage and at least one pore in communication. The control unit is used for controlling the formation of the vacuum environment of each vacuum adsorption structure according to the size of a target object to be adsorbed. The adsorption unit is used for adsorbing the target object to be adsorbed under the control of the control unit. The adsorption functions of the vacuum adsorption structures are regulated according to the sizes of circuit boards so that the false pressure head may adapt to circuit boards in different sizes. As a result, it is not required to replace a tool for false pressure head according to the size of the circuit boards, thereby achieving a universalized purpose, increasing production efficiency, reducing a reject rate of the circuit boards, and decreasing purchase cost.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a dummy indenter and a working method thereof. Background technique [0002] In the display manufacturing process, the false pressing equipment is used to perform false pressing (also known as pre-pressing, false binding) of the pin circuit lines on the circuit board and the display panel. At present, there are a wide variety of products produced by module factories, and the production equipment is also different. Each product corresponds to a circuit board. Due to the different sizes of the circuit boards, a large number of fixtures need to be replaced every time the model is switched, resulting in low production efficiency and high procurement costs. The replacement of fixtures not only takes a lot of time (accounting for about 1 / 3 of the model switching time), but also easily causes other problems during the disassembly and installation process, and also brings great inconve...
