If the application number is: 2018110069590, with patent name: in the prior application of a vacuum laminator, the up-and-down movement of the upper and lower cavities is sealed by a single servo motor cooperating with a track. The other sealing structure of the upper cavity and the lower cavity is as follows: 201810403803. X, patent name: in the prior application of the laminating device and the laminating method, the servo component is utilized to be matched with the spring on the upper cavity for sealing, although the servo drive is adopted to drive the upper cavity to move downwards, the spring can provide relatively flexible pressure, when the pressure value is too large, the damage of the cavity assembly comprising the sealing ring can still be caused after multiple operations, once the sealing ring is damaged and is not found, the vacuum degree in the sealing cavity cannot be ensured, and the vacuum laminating effect of a product is influenced.
And defect two: the traditional vacuum laminating device is generally divided into two laminating modes, wherein firstly, the upper cavity and the lower cavity are synchronously sealed and laminated, namely, the laminating pressure of the upper cavity and the lower cavity is the same as the laminating pressure of a panel and cannot be independently adjusted, so that the requirements on design precision and assembly precision are very high, on the premise of meeting the laminating pressure of the panel, if the laminating pressure of the upper cavity and the lower cavity is too high, the service life of a sealing ring on the upper cavity and the lower cavity is easily reduced, and if the laminating pressure of the upper cavity and the lower cavity is too low, the sealing in a cavity is easily poor, so that the laminating quality is influenced; secondly, cavity seal and laminating go on asynchronously from top to bottom, and the application number is: 201810403803. X, patent name: in the prior application of laminating device and laminating method, earlier with upper and lower cavity sealed, then utilize servo assembly to continue to drive upper cavity and move down, utilize the elastic component on the upper cavity to guarantee that laminating platform can continue to push down, but do not carry out the laminating equipment of rectifying to earlier stage, can probably lead to the elastic component can't provide sufficient elasticity space because the distance that needs to continue to push down is too big and lead to laminating the failure, or the elastic component compressed is too big, lead to its resilience pressure to last cavity too big and lead to the condition including the cavity assembly's of sealing washer in the circumstances, perhaps the resilience pressure of elastic component surpasss the settlement scope and leads to cavity assembly impaired or laminating not in place when leading to the laminating because of changing different products. In the patent, the downward moving speed of the upper cavity and the pressing plate is not changed in the fitting process, instantaneous overlarge pressure values can be generated in the processes of quick contact between the cavities and quick contact between the pressing plate and the bearing jig, and the damage to the cavity assembly and the pressing assembly or a product can be possibly caused by the instantaneous overlarge pressure.
And a third defect: current vacuum laminating device, product when laminating in the vacuum chamber, because the cavity is totally enclosed all around, consequently when proofreading, the staff can't observe and the position of measuring platform laminating, is difficult to rectify according to the pressfitting distance of platform in the cavity, and cavity excessive pressure about appearing easily when leading to the later stage laminating or the platform laminating pressure condition that laminates from top to bottom not in place takes place. If the application number is: 201810403803. X, patent name: in the prior application of the bonding apparatus and the bonding method, no correction is performed before bonding, and the bonding position inside cannot be observed after the vacuum chamber is sealed, so that accurate correction cannot be performed.
