[0004] In the above solution, a pressing cylinder is used to push the vacuum suction cup for film lamination. However, the following disadvantages still exist in the configuration. When the pressing cylinder is used to push the protective film for lamination, the lamination position of the protective film may be misaligned with the position of the tablet, thereby reducing the accuracy of laminating the film on the tablet. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic film-sticking device for a flat-panel protective film, so as to solve the problem that the sticking position of the protective film may be misaligned with the position of the flat panel, thereby reducing the accuracy of sticking the film on the flat panel.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions: an automatic film-sticking device for a flat-plate protective film, comprising an installation groove, the installation groove is opened on the top surface of the workbench, a placement plate is slidably provided inside the installation groove, a mounting folding plate is fixed to the top surface of the workbench, an electric push rod is fixed to the top surface of the mounting folding plate, the extension rod of the electric push rod is slidably inserted with the mounting folding plate, a fixing plate is fixed to the bottom end of the telescopic rod of the electric push rod, a plurality of vacuum suction cups are fixed to the bottom surface of the fixing plate, a positioning folding plate is fixed to the top surface of the placement plate, and two limit rods are fixed to the top surface of the positioning folding plate.

[0008] Preferably, a limiting opening is provided on the inner top surface of the sliding opening, a threaded column is fixed on the top surface of the sliding plate, the threaded column is slidably inserted into the limiting opening, and a nut is threadedly connected to the threaded column.

[0009] Preferably, stabilizing openings are respectively opened on both sides of the interior of the installation groove, and stabilizing rods are respectively fixed on both sides of the placement plate, and the stabilizing rods and the stabilizing openings are slidably inserted.

[0010] Preferably, two lifting plates are slidingly provided on the top surface of the workbench, and two sliding holes are opened on the top surface of the workbench. A sliding rod is fixed to the bottom surface of the lifting plate, and the sliding rod is slidably inserted into the sliding hole. A blocking plate is fixed to the bottom end of the sliding rod, and a spring is surrounded by the surface of the sliding rod, one end of the spring is fixed to the bottom surface of the workbench, and the other end of the spring is fixed to the top surface of the blocking plate. A rolling shaft is rotatably provided between the two lifting plates.

[0011] Preferably, support columns are fixed at the four corners of the bottom surface of the workbench, and anti-slip pads are fixed at the bottom ends of the support columns.

[0012] Compared with the prior art, the automatic film-applying device for a flat-panel protective film using the above technical solution has the following beneficial effects:

[0013] First, the staff will place the flat panel on the top surface of the placement plate and fit the right-angled edge of the flat panel to the inner side of the positioning folding plate. Then, the staff will use the vacuum suction cup to fix the top surface of the protective film to the bottom surface of the fixing plate. Then, the staff will move the placement plate inside the installation slot, so that the placement plate drives the flat panel and the limit rod to move synchronously. Finally, the limit rod will be placed on both sides of the right-angled edge of the protective film. The position between the flat panel and the protective film can be determined, which increases the accuracy of the film application.

[0014] Second, when the placement plate moves inside the installation slot, the threaded rod rotates, and the threaded connection with the placement plate drives the placement plate to move horizontally inside the installation slot. In addition, the staff can also screw the nut upward from the threaded column a little, then push the threaded column to drive the sliding plate to slide inside the sliding opening, thereby driving the placement plate to slide longitudinally inside the installation slot. After determining the position of the placement plate, the nut is screwed down on the threaded column again, and finally fits with the top surface of the workbench, thereby increasing the stability of the placement plate in the installation slot and preventing the placement plate from being displaced when the flat plate is being filmed.

[0015] 3. When the flat plate is finished with film, the staff will first apply an upward force to the lifting plate when taking the flat plate out, so that the lifting plate drives the sliding rod to move upward and compresses the spring during the upward movement. Then the staff will place the flat plate between the rolling shaft and the workbench. At this time, the rolling shaft will exert an extruding force on the film of the flat plate driven by the spring. Then the staff will push the flat plate back and forth between the rolling shaft and the workbench to squeeze out the air bubbles between the flat plate and the film, thereby increasing the film-sticking effect on the flat plate.

[0023] During use, the staff will first place the tablet on the top surface of the placement plate 3, and fit the right-angled edge of the tablet on the inner side of the positioning folding plate 8, and then use the vacuum suction cup 7 to adsorb and fix the top surface of the protective film on the bottom surface of the fixing plate 6. Then the staff will move the placement plate 3 inside the installation groove 2, so that the placement plate 3 drives the tablet and the limit rod 9 to move synchronously, and finally make the limit rod 9 rest on both sides of the right-angled edge of the protective film, so as to locate the position between the tablet and the protective film, thereby increasing the accuracy of the film.

[0024] like Figure 2 and Figure 3 As shown, sliding openings 10 are respectively provided on both sides of the interior of the mounting groove 2, and a sliding plate 11 is slidably provided inside the sliding opening 10. A threaded rod 12 is rotatably inserted into the interior of the sliding plate 11, and the threaded rod 12 is threadedly connected to the placement plate 3. A limiting opening 13 is provided on the inner top surface of the sliding opening 10, and a threaded column 14 is fixed on the top surface of the sliding plate 11. The threaded column 14 and the limiting opening 13 are slidably inserted, and a nut 15 is threadedly connected to the threaded column 14.

At this time, the rolling shaft 23 will apply an extrusion force to the film of the tablet under the drive of the spring 22. Then the staff will push the tablet back and forth between the rolling shaft 23 and the workbench 1 to squeeze out the air bubbles between the tablet and the film, thereby increasing the film application effect on the tablet.
