Secondary defoaming device and secondary defoaming method

Abstract

The invention discloses a secondary defoaming device. The secondary defoaming device comprises a first cover plate, a second cover plate and a clamp, wherein the first cover plate is arranged above the front surface of a touch product; the second cover plate is arranged under the back surface of the touch product; the clamp is used for clamping the first cover plate and the second cover plate; the clamp consists of an upper clamping sheet and a lower clamping sheet, one end of the upper clamping sheet is movably connected with one end of the lower clamping sheet, the other end of the upper clamping sheet is clamped onto the upper surface of the first cover plate, and the other end of the lower clamping sheet is clamped onto the lower surface of the second cover plate. The invention also provides the secondary defoaming method. The secondary defoaming device has the beneficial effects that by using the auxiliary device before secondary defoaming, the ratio of poor air bubbles, such as dot-shaped air bubbles and edge air bubbles which are difficult to eliminate, is reduced; the excessive detaching and consumption of materials can be avoided, the working loss is reduced, and the amounts of supplemented materials and work hours are reduced; the number of delivered products is increased, and the lack of delivery number is avoided.

Description

technical field [0001] The present invention relates to the technical field of touch products, in particular to a secondary defoaming device and a secondary defoaming method. Background technique [0002] At present, most touch screen factories will produce air bubbles during the production process due to the flatness of the lamination or the thickness of the ink on the cover plate. The existing defoaming method using a defoaming machine will cause poor bubbles. These are not good Good products cannot be eliminated after repeated defoaming after modifying the parameters of the defoaming machine. For these products, most factories will disassemble them. During the dismantling process, the sensor and a certain proportion of the cover will be lost. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a secondary defoaming device and a secondary defoaming method, using an auxiliary device before the seconda...
