Therefore, the terms used to describe positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0016] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0017] This utility model provides a protective film application device for glass cover plates, see reference. Figures 1 to 3 The protective film applicator shown mainly includes a frame platform 100 and a glass cover plate loading mechanism 1, a glass cover plate transfer mechanism 2, an applicator platform mechanism 3, a protective film loading mechanism 4, a film taking and applicating mechanism 5, a vision positioning mechanism 6, and a finished product unloading mechanism 7 connected to the frame platform 100.

[0018] In this embodiment, the glass cover plate feeding mechanism 1 and the finished product unloading mechanism 7 are respectively connected to opposite ends of the frame platform 100. The glass cover plate transfer mechanism 2 extends from above the glass cover plate feeding mechanism 1 along a first direction (in this embodiment, the length direction of the frame platform 100) across the first end of the film-applying platform mechanism 3 to above the finished product unloading mechanism 7. Specifically, the glass cover plate feeding mechanism 1 receives glass cover plates to be applied from outside the film-applying device; the glass cover plate transfer mechanism 2 transfers the glass cover plates to be applied from the glass cover plate feeding mechanism 1 to the film-applying platform mechanism 3 and transfers the applied glass cover plates from the film-applying platform mechanism 3 to the finished product unloading mechanism 7; and the finished product unloading mechanism 7 delivers the received applied glass cover plates outside the film-applying device for unloading. It should be noted that the glass cover in this embodiment is a glass cover that is assembled and bonded to the display panel. That is, the glass cover in this embodiment includes the display panel bonded to the bottom of the glass cover.

[0019] In this embodiment, the visual positioning mechanism 6 and the protective film feeding mechanism 4 are sequentially disposed on the second end side of the film-applying platform mechanism 3. The film-grabbing and applying mechanism 5 extends from above the protective film feeding mechanism 4 across the visual positioning mechanism 6 in a first direction to above the second end of the film-applying platform mechanism 3. The protective film feeding mechanism 4 is used to supply protective film. The film-grabbing and applying mechanism 5 is used to grab the protective film from the protective film feeding mechanism 4 and transfer the protective film to the top of the film-applying platform mechanism 3, and then apply it to the glass cover plate mounted on the film-applying platform mechanism 3. The visual positioning mechanism 6 is used to visually position the protective film grabbed on the film-grabbing and applying mechanism 5.

[0020] In this embodiment, the film-applying platform mechanism 3 extends along a second direction (in this embodiment, the width direction of the frame platform 100) and is configured to reciprocate between the area below the glass cover plate transfer mechanism 2 and the area below the film-applying mechanism 5. The film-applying platform mechanism 3 first receives the glass cover plate to be applied from the glass cover plate transfer mechanism 2, then transfers the glass cover plate to be applied to the area below the film-applying mechanism 5 for film application, and finally transfers the applied glass cover plate back to the area below the glass cover plate transfer mechanism 2, whereby the glass cover plate transfer mechanism 2 transfers the applied glass cover plate to the finished product unloading mechanism 7.

[0021] In this embodiment, see Figure 4 and Figure 5 and combined Figures 1 to 3As shown, the film-applying platform mechanism 3 includes a first linear drive module 31, a UVW platform 32, a vacuum adsorption platform 33, and positioning components 34. The first linear drive module 31 extends along a second direction and from below the glass cover plate transfer mechanism 2 to below the film-applying mechanism 5. The UVW platform 32 is movably connected to the first linear drive module 31. The vacuum adsorption platform 33 is connected to the UVW platform 32. A positioning component 34 is connected to each of two adjacent sides of the vacuum adsorption platform 33. The positioning component 34 is vertically higher than the surface of the vacuum adsorption platform 33. The vacuum adsorption platform 33 carries the glass cover plate, and the positioning components 34 position the glass cover plate from the side. The two positioning components 34 position the glass cover plate from two adjacent sides, thereby specifically defining the position of the glass cover plate on the vacuum adsorption platform 33. The UVW platform 32 adjusts the position of the vacuum adsorption platform 33, thereby adjusting the specific coordinates of the glass cover plate, achieving precise alignment between the glass cover plate and the protective film during application. The first linear drive module 31 is used to drive the UVW platform 32 to move, thereby driving the vacuum adsorption platform 33 to transfer the loaded glass cover plate between the glass cover plate transfer mechanism 2 and the film taking and applying mechanism 5.

[0022] Specifically, the positioning component 34 includes a lateral drive module 341, a connecting bracket 342, and positioning posts 343. The lateral drive module 341 is fixedly connected to the side of the vacuum adsorption platform 33, and the connecting bracket 342 is movably connected to the lateral drive module 341. Multiple positioning posts 343 are sequentially and spaced apart from each other along the side length of the vacuum adsorption platform 33, and the vertical height of each positioning post 343 is higher than the surface of the vacuum adsorption platform 33. The positioning posts 343 are used to stop the glass cover from the side, thereby defining the position of the glass cover. The lateral drive module 341 drives the connecting bracket 342 to move, which in turn moves the positioning posts 343, thereby adjusting the distance between the positioning posts 343 and the side of the vacuum adsorption platform 33. This allows the positioning component 34 to be applicable to glass covers of various sizes and specifications.

[0023] Before applying the film, the size of the glass cover to be filmed is determined. The distance between the positioning post 343 and the side of the vacuum adsorption platform 33 is adjusted to the corresponding position by the lateral drive module 341. Then the film application is started. The glass cover is loaded onto the vacuum adsorption platform 33 by the glass cover transfer mechanism 2 and placed tightly against the positioning post 343. This defines the specific position of the glass cover on the vacuum adsorption platform 33. After obtaining the position information of the vacuum adsorption platform 33, the film application device can obtain the position information of the glass cover loaded on it, which facilitates the subsequent precise alignment with the protective film.

[0024] As a preferred embodiment, in this case, the positioning post 343 is rotatably connected to the connecting bracket 342. By providing the rotatable positioning post 343, during the lateral movement of the glass cover plate when loading it, the positioning post 343 rolls into contact with the side of the glass cover plate, preventing the positioning post 343 from scratching the side of the glass cover plate.

[0025] In this embodiment, see Figure 6 and combined Figures 1 to 3 As shown, the glass cover plate transfer mechanism 2 includes a second linear drive module 21 and a glass cover plate gripping robot 22. The second linear drive module 21 extends from above the glass cover plate loading mechanism 1 across the first end of the film-applying platform mechanism 3 in a first direction to above the finished product unloading mechanism 7. The glass cover plate gripping robot 22 is movably connected to the second linear drive module 21. The glass cover plate gripping robot 22 is configured to adsorb and grip glass cover plates. The second linear drive module 21 is used to drive the glass cover plate gripping robot 22 to reciprocate between the glass cover plate loading mechanism 1 and the finished product unloading mechanism 7 via the film-applying platform mechanism 3, thereby realizing the transfer of the glass cover plate to be coated from the glass cover plate loading mechanism 1 to the film-applying platform mechanism 3 and the transfer of the coated glass cover plate from the film-applying platform mechanism 3 to the finished product unloading mechanism 7.

[0026] In this embodiment, see Figure 7 and combined Figures 1 to 3As shown, the protective film feeding mechanism 4 is a roll-to-roll feeding and receiving mechanism, which includes a film peeling platform 41, a feeding roller 42, and a receiving roller 43. The film peeling platform 41 is located below the film taking and applying mechanism 5, and the feeding roller 42 and the receiving roller 43 are respectively located on the side of the film peeling platform 41. The feeding roller 42 conveys the film substrate with the protective film attached in a roll shape from the first end of the film peeling platform 41 onto the film peeling platform 41. Multiple guide rollers can be provided between the feeding roller 42 and the first end of the film peeling platform 41 to facilitate the conveying of the film substrate. The film-attaching mechanism 5 adsorbs and grasps the protective film on the film-peeling platform 41 and peels it off from the film substrate. The take-up roller 43 pulls the film substrate after the protective film has been peeled off downwards along the second end of the film-peeling platform 41 and winds it back up. Multiple guide rollers can be provided between the take-up roller 43 and the second end of the film-peeling platform 41 to facilitate the conveying of the film substrate. The second end of the film-peeling platform 41 has a chamfered bevel 41a that slopes downwards and toward the first end of the film-peeling platform 41.

[0027] It should be noted that a protective film corresponding to the size of the glass cover is attached to the membrane substrate. Multiple protective films are independently attached to the membrane substrate and are sequentially conveyed to the peeling stage 41 along with the membrane substrate. By forming the chamfered bevel 41a at the second end of the peeling stage 41, after the membrane substrate feeds a protective film attached to it into the peeling stage 41, the membrane substrate is pulled downward and backward along the chamfered bevel 41a from the second end of the peeling stage 41. At this time, the protective film can be initially separated from the membrane substrate, which facilitates the subsequent adsorption, gripping and peeling of the protective film by the film-attaching mechanism 5.

[0028] In this embodiment, see Figure 8 and Figure 9 and combined Figures 1 to 3As shown, the film-attaching mechanism 5 includes a third linear drive module 51 and a film-attaching robot 52. The third linear drive module 51 extends from above the protective film feeding mechanism 4 across the visual positioning mechanism 6 in a first direction to above the second end of the film-attaching platform mechanism 3. The film-attaching robot 52 is movably connected to the third linear drive module 51. The film-attaching robot 52 is configured to adsorb and grasp the protective film and press it onto the glass cover plate mounted in the film-attaching platform mechanism 3. The third linear drive module 51 drives the film-attaching robot 52 to reciprocate between the protective film feeding mechanism 4 and the film-attaching platform mechanism 3 via the visual positioning mechanism 6, thereby enabling the protective film to be grasped from the protective film feeding mechanism 4 and transferred to the visual positioning mechanism 6 for visual positioning, and then transferred to the film-attaching platform mechanism 3 to be attached to the glass cover plate.

[0029] Specifically, the film-attaching robot 52 includes a first lifting drive module 521, a connecting plate 522, a protective film adsorption assembly 523, a swing drive assembly 524, a second lifting drive module 525, and a top pressure roller shaft 526. The first lifting drive module 521 is movably connected to the third linear drive module 51. The connecting plate 522 is connected to the output end of the first lifting drive module 521. The protective film adsorption assembly 523 is connected below the connecting plate 522 and is interconnected with the connecting plate 522 via the swing drive assembly 524. The swing drive assembly 524 is configured to drive the protective film adsorption assembly 523 to rotate relative to the connecting plate 522. The top pressure roller shaft 526 is disposed on the side of the protective film adsorption assembly 523 and connected to the connecting plate 522 via the second lifting drive module 525.

[0030] The swing drive assembly 524 includes a rotating connecting shaft 5241 and a third lifting drive module 5242. The protective film adsorption assembly 523 is rotatably connected to the bottom of the connecting plate 522 via the rotating connecting shaft 5241. The third lifting drive module 5242 is fixedly connected to the side of the connecting plate 522 on the side opposite to the second lifting drive module 525. The output end of the third lifting drive module 5242 is connected to the protective film adsorption assembly 523.

[0031] The robotic arm 52 for film removal and application as described above: When the protective film is picked up from the protective film feeding mechanism 4, firstly, the third lifting drive module 5242 drives the protective film adsorption component 523 to rotate around the rotating connecting shaft 5241 to a horizontal state; then, the first lifting drive module 521 drives the connecting plate 522 to move the protective film adsorption component 523 down to press against the film peeling platform 41, and the protective film adsorption component 523 picks up the protective film attached to the film substrate through vacuum adsorption; finally, the first lifting drive module 521 drives the protective film adsorption component 523 to rise again, thereby adsorbing and picking up the protective film from the film substrate.

[0032] When applying the protective film to the glass cover: First, the third lifting drive module 5242 drives the protective film adsorption assembly 523 to rotate around the rotating connecting shaft 5241, causing one end of the protective film adsorption assembly 523 near the top pressure roller shaft 526 to descend while the other end rises, forming an inclined shape; then, the first lifting drive module 521 drives the connecting plate 522 to lower the protective film adsorption assembly 523, causing the protective film adsorbed on the protective film adsorption assembly 523 to descend near the top pressure roller shaft 526. One end of the roller 526 is pressed and attached to the glass cover plate; then, the second lifting drive module 525 drives the top pressure roller 526 to descend until it is flush with the upper surface of the glass cover plate, and the third linear drive module 51 drives the film-taking and film-applying robot 52 to move in the direction of the protective film feeding mechanism 4. The protective film gradually detaches from the protective film adsorption component 523 and is attached to the glass cover plate, and the top pressure roller 526 rolls the protective film from above, so that the protective film is firmly attached to the surface of the glass cover plate.

[0033] It should be noted that after the film-grabbing and applying robot 52 grasps the protective film, it is first driven by the third linear drive module 51 to above the visual positioning mechanism 6, where the visual positioning mechanism 6 performs visual positioning of the protective film grasped on the film-grabbing and applying robot 52. After visual positioning is completed, the third linear drive module 51 drives the film-grabbing and applying robot 52 to above the film-applying platform mechanism 3 for precise alignment. This includes: based on the position information of the glass cover plate mounted on the vacuum adsorption platform 33 and the position information of the protective film obtained by the visual positioning mechanism 6, preliminary alignment is first performed by driving the vacuum adsorption platform 33 with the first linear drive module 31 and driving the film-grabbing and applying robot 52 with the third linear drive module 51; then, the UVW platform 32 adjusts the specific position coordinates of the vacuum adsorption platform 33 to achieve precise alignment between the glass cover plate and the protective film. After precise alignment is completed, the film-grabbing and applying robot 52 then applies the protective film to the glass cover plate.

[0034] The visual positioning mechanism 6 is a CCD visual positioning mechanism commonly used in the field, and the finished product unloading mechanism 7 is a conveyor belt mechanism commonly used in the field.

[0035] In summary, the protective film applicator for glass covers provided in this embodiment integrates a glass cover loading mechanism, a glass cover transfer mechanism, an applicator platform mechanism, a protective film loading mechanism, a film picking and applicating mechanism, a visual positioning mechanism, and a finished product unloading mechanism into a single applicator. From loading the glass cover and protective film, to their mutual alignment and applicability, and finally to unloading the applicated product, all processes are automated, thereby improving the efficiency of applicating protective film onto glass covers and consequently increasing production efficiency. Specifically, by incorporating a positioning mechanism within the applicator platform for positioning the loaded glass cover, combined with a visual positioning mechanism for visually positioning the protective film gripped by the film picking and applicating mechanism, precise alignment of the glass cover and protective film can be achieved before applicator application, improving applicator accuracy.

[0036] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
