Description

Technical Field

[0001] The present invention relates to the technical field of screen protection, and in particular to a mobile terminal film laminating machine and a protective film assembly separation mechanism and a film tearing device thereof. Background Art

[0002] With the development of science and technology, electronic products have become widely popular. People's production and life are inseparable from various electronic devices, such as mobile terminals such as smart phones or tablet computers. The screen of the mobile terminal is an important part of the entire mobile phone, which is easy to be damaged and expensive. Once it is accidentally dropped, the screen is easy to be broken, causing great losses to the user. Therefore, there is a need to protect the electronic screen of the mobile device. People usually apply a layer of protective film on the surface of the screen of mobile terminals such as smart phones or tablet computers to protect the display screen of the mobile terminal and prevent the display screen from being accidentally scratched and cracked. In order to improve the efficiency of film pasting, an automatic film pasting machine can be used instead of manual film pasting.

[0003] Since the protective film needs colloid to bond with the screen, in order to protect the colloid and prevent it from adhering to other impurities, dust or other structures during transportation and causing it to fall off, a substrate is connected to one side of the protective film with the colloid, and the colloid is hidden between the substrate and the protective film, thereby protecting the colloid. Therefore, the protective film and the substrate are usually used to form a protective film assembly for transportation and storage.

[0004] In an automatic film laminating machine, when the protective film needs to be attached to the screen, the substrate needs to be torn off. The current process of tearing off the substrate is usually: the vacuum clamping mechanism adsorbs on the top of the protective film, and then the vacuum clamping mechanism moves to drive the entire protective film assembly to be taken out from the film bin, and then the finger cylinder clamps the part of the substrate protruding outside one side of the protective film, and the finger cylinder moves downward to tear the substrate off from the bottom of the protective film, thereby realizing the film tearing operation. However, due to the weak adsorption force of the vacuum clamping mechanism, when the tearing force is too strong, it is easy to cause the protective film to separate from the vacuum clamping mechanism, causing the protective film assembly to fall off from the vacuum clamping mechanism as a whole, resulting in film tearing failure. The fallen protective film assembly is also easy to affect the operation of the internal components of the automatic film laminating machine. Summary of the invention

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0034] See also Figure 1 and Figure 2 An embodiment of the present invention provides a film tearing device, including: a clamping mechanism 10, a translation drive component 20 and a protective film component separation mechanism 30 of a mobile terminal film laminating machine, the translation drive component 20 is drivingly connected to the clamping mechanism 10, and the clamping mechanism 10 is used to grab the protective film component.

[0035] See also Figure 3 The protective film assembly separation mechanism 30 of the mobile terminal film laminating machine includes: a support seat 40 and a substrate end limiting assembly 50.

[0036] A support portion 41 is provided on the top of the support seat 40, and the support portion 41 is used to support the substrate 61 of the protective film assembly in the first direction. The substrate end limiting assembly 50 is provided on one side of the support portion 41, and is used to apply a force in the second direction to the film tearing area 62 of the substrate 61. When the protective film assembly moves along the support seat 40 toward the substrate end limiting assembly 50, the end of the substrate 61 is driven to move in the second direction, so that the substrate 61 is separated from the protective film body 60, wherein the first direction and the second direction are opposite. The clamping mechanism 10 can cooperate with the support seat 41 to clamp the protective film assembly.

[0037] See also Figure 4 In this embodiment, the separation of the protective film assembly is taken as an example for explanation, wherein the protective film assembly includes a substrate 61 and a protective film body 60 arranged on the substrate 61, and a bearing area and a film tearing area 62 are arranged on the substrate 61. The protective film body 60 is arranged on the bearing area, and the film tearing area 62 is located at the end of the substrate 61, protruding from one side of the protective film body 60.

[0038] See also Figures 5 to 7 Before tearing the film, the translation drive assembly 20 drives the clamping mechanism 10 to move to the top of the protective film assembly, and then the clamping mechanism 10 grabs the top of the protective film body 60 of the protective film assembly, and then the translation drive assembly 20 drives the protective film assembly to move onto the support portion 41, so that the protective bottom plate 55 of the protective film assembly rests on the top of the support portion 41.

[0039] When tearing the film, the clamping mechanism 10 moves along the direction from the support part 41 to the substrate end limiting component 50 under the drive of the translation driving component 20, so that the protective film component moves along the support part 41 until the film tearing area 62 of the substrate 61 extends out of one side of the support part 41, and the substrate end limiting component 50 is connected to the film tearing area 62 of the substrate 61, and then moves in the second direction, so that the film tearing area 62 of the substrate 61 moves in the second direction, and drives the substrate 61 to bend so that a part of the protective film body 60 close to the film tearing area 62 is peeled off from the substrate 61. When the substrate 61 and the protective film body 60 are peeled off from each other, due to the adhesion between the substrate 61 and the protective film body 60, the substrate 61 will pull downward the parts of the protective film body 60 and the substrate 61 that have not yet been separated. However, since the support part 41 can provide support in the first direction for the parts of the protective film body 60 and the substrate 61 that have not yet been separated, the pulling caused by the adhesion is offset, thereby effectively preventing the protective film body 60 from loosening from the clamping mechanism 10.

[0040] Then, the clamping mechanism 10 continues to move toward the pressing member 51 under the drive of the translation drive assembly 20, so that the protective film assembly continues to move along the support portion 41 toward the substrate end limit assembly 50, and the unseparated parts of the protective film body 60 and the substrate 61 will gradually peel off from each other until the protective film body 60 and the substrate 61 are completely separated from each other, and the film tearing operation can be achieved. In the process of the protective film body 60 and the substrate 61 gradually peeling off from each other, the support portion 41 can provide a supporting force in the first direction to the protective film body 60 and the substrate 61 that are still on the support portion 41, especially to support the position close to the protective film body 60 and the substrate 61 that are about to peel off from each other, thereby preventing the protective film body 60 from falling off from the clamping mechanism 10.

[0041] Therefore, the design of the support portion 41 and the special film tearing operation ensure that the protective film body 60 is stably stressed during the film tearing process and is not easily removed from the clamping mechanism 10 , thereby effectively improving the success rate of film tearing.

[0042] See also Figure 3The specific structure of the substrate end limiting component 50 can be designed according to actual needs. The substrate end limiting component 50 can absorb the end of the substrate 61 by adsorption and then move the end of the substrate 61 to the second direction. The substrate end limiting component 50 can also clamp the end of the substrate 61 and then pull it in the second direction. Alternatively, the substrate end limiting component 50 can also push the end of the substrate 61 to the second direction by pushing. Figure 2 In this embodiment, the substrate end limiting assembly 50 adopts a pushing method, and its structure can adopt a suitable structure to press the substrate 61. For example, in some optional embodiments, the substrate end limiting assembly 50 includes a pressing member 51 and a lifting drive module 52. The lifting drive module 52 is drivingly connected to the pressing member 51. The pressing member 51 is arranged on the front side of the support portion 41 in a lifting manner to push the end of the substrate 61 of the protective film assembly along the second direction. When tearing the film, the pressing member 51 presses on the film tearing area 62 at the end of the substrate 61 and pushes it in the second direction, so that the substrate 61 is bent and peeled off from the protective film body 60.

[0043] In some optional embodiments, the pressure piece 51 is a cylindrical lower pressure roller, which is horizontally arranged on the front side of the support portion 41 and rotatably cooperates with the lifting drive module 52. The pressure piece 51 adopts a cylindrical lower pressure roller design, so that the side curved surface of the pressure piece 51 can more smoothly separate the protective film body 60 and the substrate 61, and the pressure piece 51 adopts a rolling design. When the protective film assembly moves along the support portion 41 to drive the substrate 61 to be gradually peeled off, the pressure piece 51 can roll relative to the substrate 61, thereby reducing the jamming phenomenon and improving the smoothness of the movement of the substrate 61.

[0044] In order to facilitate the rotational coordination between the lifting drive module 52 and the lower pressure roller, in some optional embodiments, a lifting frame 53 is provided on one side of the support seat 40, and the pressure piece 51 is rotatably provided on the lifting frame 53. The lifting drive module 52 is driven and connected to the pressure piece 51 through the lifting frame 53. The lifting drive module 52 drives the lifting frame 53 to rise and fall, thereby driving the pressure piece 51 to rise and fall.

[0045] In some optional embodiments, a plurality of guide sleeves 43 are provided on the front end of the support seat 40, and a plurality of guide columns 54 are provided on the lifting frame 53. The guide columns 54 are slidably matched with the guide sleeves 43 and are driven and connected to the lifting drive module 52. The cooperation between the guide columns 54 and the guide sleeves 43 is beneficial to improving the movement stability of the pressing member 51, and can avoid the offset angle and shaking of the pressing member 51.

[0046] See also Figure 8In some optional embodiments, the lifting frame 53 includes a bottom plate 55 and two side plates 56 respectively arranged on both sides of the bottom plate 55 and extending upward. The pressure piece 51 is connected between the two side plates 56. An avoidance gap is formed between the bottom plate 55 and the pressure piece 51 for a substrate 61 of the protective film assembly to pass through. Before tearing the film, the film tearing area 62 of the substrate 61 extends into the avoidance gap, and the avoidance gap allows the substrate 61 to pass through. After the film tearing is completed, the substrate 61 detaches from the avoidance gap.

[0047] In some optional embodiments, the support portion 41 includes a plurality of support rollers 42, which are rotatably matched with the support seat 40, and the plurality of support rollers 42 are arranged in sequence in a direction close to the substrate end limiting assembly 50. When the protective film assembly moves along the support portion 41, the support rollers 42 and the protective film assembly are in sliding friction, which is beneficial to improving the smoothness of the movement of the protective film body 60.

[0048] When tearing the film, the pressing member 51 can be designed to keep a certain distance from the protective film body 60 in the second direction when pressing the substrate 61, so that when the protective film assembly moves along the support portion 41, the side of the protective film body 60 facing the pressing member 51 is not easy to contact the pressing member 51, thereby preventing the colloid on the protective film body 60 from touching the pressing member 51, and further preventing the colloid from adhering to the pressing member 51 or causing scratches. Preferably, during the entire film tearing operation, it should be avoided that the bottom of the protective film body 60 with the colloid is in contact with the pressing member 51, so as to avoid scratches that affect the appearance due to the adhesion of the colloid to other structures.

[0049] In some optional embodiments, the clamping mechanism 10 includes a movable bracket 11 and a plurality of vacuum suction cups 12, the movable bracket 11 is connected to the translation drive assembly 20, and the plurality of vacuum suction cups 12 are arranged at the bottom of the movable bracket 11, and the vacuum suction cups 12 generate negative pressure to achieve adsorption on the top of the protective film body 60. Of course, the clamping mechanism 10 can also be grasped on the top of the protective film body 60 by other structures, not limited to the vacuum adsorption method.

[0050] The film tearing device of the mobile terminal film laminating machine described above can be applied to the mobile terminal film laminating machine, and the mobile terminal film laminating machine includes: the film tearing device of the mobile terminal film laminating machine described above. In this embodiment, a film bin mechanism is provided in the mobile terminal film laminating machine, and the translation drive assembly 20 can drive the clamping mechanism 10 to move between the support seat 40 and the film bin mechanism.

[0051] The specific structure of the translation drive assembly 20 can be designed according to actual needs. For example, the translation drive assembly 20 is a three-axis translation drive assembly 20, which can realize the movement of the clamping mechanism 10 in the lateral, longitudinal and up and down directions. The principle of the three-axis translation drive assembly 20 is a technology well known to technical personnel in this field and will not be repeated here.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
