The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art through specific situations.
FIG. 1 is a schematic diagram of a module frame according to the glue filling method of the present invention; FIG. 2 is a schematic view of the working state of the glue filling method of the present invention; FIG. 3 is a second schematic view of the working state of the glue filling method of the present invention; FIG. 4 is a flow chart of the glue filling method of the present invention.
Referring to fig. 1 and 4, a glue filling method for a large-sized fully-bonded product, in which a plurality of glue needles are simultaneously filled to reduce the time required for the glue filling process, includes the following steps 10-50.
Step 10: a cover plate and a module frame 1 are provided. The module frame 1 is used for limiting the module, and the module can comprise a liquid crystal module, a touch module and the like. The cover plate is used for being fixed with the module frame 1 in a laminating mode, and a glue filling space is formed inside the module frame after the laminating mode is conducted. The display area 3 and a plurality of non-display area 2 that the module frame 1 inboard was separated for the bottom intercommunication, and display area 3 corresponds the display function region of product, and this region of product can not receive the bubble influence that the encapsulating produced. The module frame 1 is provided with an exhaust hole 4 for exhausting air and a plurality of glue filling holes 5 for filling glue, and the glue filling holes 5 can also be used for exhausting air. Exhaust hole 4 and encapsulating hole 5 correspond respectively and communicate display area 3 and non-display area 2, and is specific, and exhaust hole 4 is seted up on the module frame 1 at display area 3 top, and encapsulating hole 5 is seted up on the module frame 1 of non-display area 2.
Step 20: and (3) combining the cover plate and the module frame 1 for fixation, forming a glue filling space inside after the combination, and preparing for glue filling action.
Step 30: referring to fig. 2, glue is injected into the non-display area 2 through the glue injection hole 5. Traditional module frame 1 closes the piece with the apron after, carries out the encapsulating from both sides encapsulating hole 5, and glue goes out to glue and becomes irregular arc, when left and right sides glue assembles, very easily forms the bubble, because the bubble receives buoyancy effect, the part can the come-up, but has the bubble can not come-up to the glue surface condition, causes the encapsulating bubble bad. In order to further expel the bubbles, at least one non-display area 2 is not filled with glue through the corresponding glue filling hole 5, the exhaust hole 4 can exhaust gas at the moment, the glue filling hole 5 which is not filled with glue can also assist in exhausting, and the glue can be stably filled into the bottom of the display area 3, so that the situation that the glue at the two sides is filled with the glue at the same time and is converged into the bubbles is prevented.
Step 40, referring to fig. 3, as the glue is gradually gathered, when the glue submerges the bottom communication portion of the display area 3 and the non-display area 2, the glue is injected into the non-display area 2 which is not injected with the glue through the corresponding glue injection hole 5. The glue filling operation is carried out by opening the glue needle on one side firstly, when the glue submerges the lowest point, the glue filling operation is carried out by opening the glue needle on the other side simultaneously, and the bubbles formed by the convergence of the glue can be blocked outside the display area 3. The liquid pressure at the same height is equal, so the display area 3 can be stably filled with the glue along with the increase of the glue at the two sides, and air bubbles can not be generated in the display area 3 due to the convergence of the glue at the two sides, thereby reducing the defect rate of the air bubbles.
And step 50, after the inner side of the module frame 1 is filled with glue, and the glue injection is finished, sealing the glue injection hole 5 and the exhaust hole 4 by using sealant.
In one embodiment, step 10: the inner side of the module frame 1 is provided with a partition fence which is also called as a partition plate and is used for separating the inner side area of the module frame 1 so that the glue in each separated area is communicated only through the bottom. The inner area of the frame 1 of the barrier separation module is a display area 3 and a non-display area 2, preferably, the display area 3 is centered and the non-display area 2 is distributed on two sides of the display area 3.
In one embodiment, the partition is vertically arranged, the top of the partition is fixed with the module frame 1, a gap is reserved between the bottom of the partition and the module frame 1, the display area 3 is communicated with the non-display area 2 through the gap, and the top of the partition is communicated with the outside through the glue filling hole 5 and the exhaust hole 4, so that a communicating vessel is formed between the areas.
In one embodiment, the partition has a pair, and the partition divides the inner area of the module frame 1 into a central display area 3 and two non-display areas 2 on two sides. Preferably, the two non-display regions 2 have the same area.
In one embodiment, in step 10: the exhaust hole 4 is arranged on the central axis of the display area 3, so that air is uniformly exhausted, and bubbles are prevented from being generated due to uneven glue on any side.
In one embodiment, step 30: the non-display areas 2 without glue are at least half of the number of all the non-display areas 2, so that the air exhaust and glue filling in the initial glue injection stage are more stable, and the generation of bubbles in the display areas 3 is reduced.
In one embodiment, step 30: the glue filling hole 5 also has the function of the exhaust hole 4, and the extruded gas can be exhausted through the exhaust hole 4 and the glue filling hole 5 after the glue is injected.
Compared with the prior art, the invention has the following beneficial effects: according to the glue pouring method, the glue is poured by utilizing the plurality of glue pouring holes, so that the efficiency is high; set up multiple region through separating, will be easily separated by the bad display area of bubble to make non-display area and display area form the linker between each other, through irritate glue through non-display area in proper order, make display area can be steady fill up by glue, and can not assemble and produce the bubble at display area because of both sides glue, thereby reduce the bubble defective rate.
In light of the foregoing description of the preferred embodiments according to the present application, it is to be understood that various changes and modifications may be made without departing from the spirit and scope of the invention. The technical scope of the present application is not limited to the contents of the specification, and must be determined according to the scope of the claims.
