[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application.

[0032] In addition, it needs to be explained that, in the description of the present application, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, it can be directly connected, or indirectly connected through an intermediate medium, it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] As shown in Figures 1-2 The prior art film covering jig 1 is in a plate structure, mainly used for fixing the glass cover plate 2, so as to paste the protective film on the glass cover plate 2. The size of the film covering jig 1 in the first direction is the same as the size of the glass cover plate 2 in the first direction, and the size of the film covering jig 1 in the second direction is the same as the size of the glass cover plate 2 in the second direction, the first direction and the second direction are perpendicular to each other. When the front surface of the glass cover plate 2 needs to be covered with a film, the back surface of the glass cover plate 2 needs to be attached to the film covering jig 1, so that the front surface of the glass cover plate 2 is exposed, thereby facilitating the pasting of the protective film on the front surface of the glass cover plate 2. When the back surface of the glass cover plate 2 needs to be covered with a film, the front surface of the glass cover plate 2 needs to be attached to the film covering jig 1, so that the back surface of the glass cover plate 2 is exposed, thereby facilitating the pasting of the protective film on the back surface of the glass cover plate 2. When the glass cover plate 2 is applied to a mobile phone, it is necessary to coat ink on the back surface of the glass cover plate 2 to form a light shielding area 22 and a light transmitting area 21 on the glass cover plate 2. However, when the front surface of the glass cover plate 2 is covered with a film, the film covering jig 1 directly contacts the light shielding area 22 on the back surface of the glass cover plate 2, which makes the light shielding area 22 easily contaminated, and seriously affects the adhesion and color performance of the ink in the subsequent ink coating process, which makes the stability of the ink worse and the color difference bad rate increases.

[0034] As shown in Figures 3-5 In order to solve the problem of how to avoid the light shielding area 22 of the glass cover plate 2 from being contaminated by contacting the film covering jig 1 during the film covering process of the glass cover plate 2, the edge of the film covering jig 1 of the present application is inwardly recessed to form a first avoidance area 12 surrounding the main body area 11 of the film covering jig 1, the main body area 11 corresponds to the light transmitting area 21 of the glass cover plate 2, and the first avoidance area 12 corresponds to the light shielding area 22 of the glass cover plate 2; in the first direction, the size of the main body area 11 is L1, and the size of the light transmitting area is L2, L1 < L2; in the second direction perpendicular to the first direction, the size of the main body area 11 is H1, and the size of the light transmitting area is H2, H1 < H2.

[0035] The application sets the first empty area 12 outside the main body area 11, the main body area 11 corresponds to the light transmission area 21 of the glass cover plate 2, and the size of the main body area 11 is smaller than that of the light transmission area 21, so that when the glass cover plate 2 needs to be coated, the light transmission area 21 of the glass cover plate 2 can only contact the main body area 11 of the coating jig 1, and the light shielding area 22 of the glass cover plate 2 will not contact the coating jig 1 due to the existence of the first empty area 12, thereby avoiding the problem that the light shielding area 22 is easily contaminated due to contact with the coating jig 1, and further ensuring the adhesion and color performance of the ink in the subsequent ink coating process, improving the stability of the ink, and greatly reducing the color difference of the glass cover plate 2.

[0036] It should be noted that the first direction in the present application refers to the Y direction in the present application, wherein the Y direction includes the direction indicated by the arrow or the opposite direction indicated by the arrow. The second direction refers to the X direction in the present application, wherein the X direction includes the direction indicated by the arrow or the opposite direction indicated by the arrow. The first direction and the second direction are perpendicular to each other. Figures 1-5 Figures 1-5 It should be noted that the first direction in the present application refers to the Y direction in the present application, wherein the Y direction includes the direction indicated by the arrow or the opposite direction indicated by the arrow. The second direction refers to the X direction in the present application, wherein the X direction includes the direction indicated by the arrow or the opposite direction indicated by the arrow. The first direction and the second direction are perpendicular to each other.

[0037] The following will further refer to Figures 3-5 , a preferred embodiment of the coating jig 1 of the present application is introduced. Those skilled in the art can understand that the following embodiments are only used to illustrate the principles of the present application, and are not intended to limit the protection scope of the present application. Under the premise that the coating jig 1 at least includes the first empty area 12 and the main body area 11, those skilled in the art can adjust the following setting mode so that the present application can be applied to more specific application scenarios.

[0038] Next, referring to Figures 3-5 , the coating jig 1 includes the first empty area 12 and the main body area 11. The first empty area 12 is arranged outside the main body area 11 and surrounds the main body area 11, and is recessed inward relative to the main body area 11. The back surface of the glass cover plate 2 includes the light transmission area 21 and the light shielding area 22. The light shielding area 22 is arranged around the light transmission area 21. The first empty area 12 corresponds to the light shielding area 22, and the main body area 11 corresponds to the light transmission area 21. Through the above setting mode, when the front surface of the glass cover plate 2 is coated, the light transmission area 21 is attached to the main body area 11, and the light shielding area 22 will not contact the coating jig 1 due to the existence of the first empty area 12, thereby avoiding the problem that the light shielding area 22 is easily contaminated due to contact with the coating jig 1.

[0039] It should be noted that the present application does not limit the material of the coating jig 1, as long as the glass cover plate 2 installed on the coating jig 1 can be attached to the protective film. For example, the material of the coating jig 1 can be acrylic or bakelite. In addition, the present application also does not limit the material of the glass cover plate 2, which can be microcrystalline glass. The glass cover plate 2 of this material has good anti-falling performance.​

[0040] Next, referring to Figures 3-5 In the first direction, the size of the main body area 11 is L1, and the size of the light-transmitting area 21 is L2. Wherein, 0.8mm≤(L2-L1)≤2mm. In the second direction, the size of the main body area 11 is H1, and the size of the light-transmitting area is H2. Wherein, 0.8mm≤(H2-H1)≤2mm. By limiting the size difference between the light-transmitting area 21 and the main body area 11, the light-transmitting area 21 of the glass cover plate 2 is aligned with the main body area 11, the glass cover plate 2 is installed on the film coating jig, and the problem of the light-blocking area 22 being easily contaminated by contacting the main body area 11 is avoided.

[0041] It should be noted that the range of the size difference between the light-transmitting area 21 and the main body area 11 is not fixed, and those skilled in the art can adjust it according to the specific size of the main body area 11 and the light-transmitting area 21, as long as L1<L2 in the first direction and H1<H2 in the second direction. In addition, the size relationship between the overall size of the film coating jig and the overall size of the glass cover plate is not limited, as long as the size of the main body area 11 is smaller than the size of the light-transmitting area 21 in the first direction and the size of the main body area 11 is smaller than the size of the light-transmitting area 21 in the second direction. For example, in the first direction, the size L3 of the film coating jig 1 can be the same as the size L4 of the glass cover plate 2, or the size L3 of the film coating jig 1 is greater than the size L4 of the glass cover plate 2, or the size L3 of the film coating jig 1 is smaller than the size L4 of the glass cover plate 2. And / or, in the second direction, the size H3 of the film coating jig 1 can be the same as the size H4 of the glass cover plate 2, or the size H3 of the film coating jig 1 is greater than the size H4 of the glass cover plate 2, or the size H3 of the film coating jig 1 is smaller than the size H4 of the glass cover plate 2.

[0042] Next, referring to Figures 3-5 In addition to the light-transmitting area 21 and the light-blocking area 22, the back of the glass cover plate 2 also includes a camera area 23. The camera area 23 also needs to be coated with ink, so in order to avoid the camera area 23 of the glass cover plate 2 being easily contaminated by contacting the film coating jig 1, a second avoidance area 13 can be provided on the film coating jig 1. The second avoidance area 13 is formed by part of the main body area 11 being inwardly recessed, the recessed direction of the second avoidance area 13 is the same as that of the first avoidance area 12, and the second avoidance area 13 corresponds to the camera area 23 of the glass cover plate 2. The outer diameter of the second avoidance area 13 is d1, and the outer diameter of the camera area 23 is d2. Wherein, 1mm≤(d1-d2)≤3mm. By limiting the size difference between the second avoidance area 13 and the camera area 23, the camera area 23 will not contact the film coating jig 1 due to the presence of the second avoidance area 13, thereby avoiding the problem of the camera area 23 being easily contaminated by contacting the film coating jig 1.

[0043] It should be noted that the range of the size difference between the second avoidance area 13 and the camera area 23 is not fixed, and those skilled in the art can adjust it according to the specific size of the camera area 23, as long as d1>d2.

[0044] Next, referring to Figure 3 and 5 , in the third direction, the recess size of the first avoidance area 12 is D1, and the recess size of the second avoidance area 13 is D2. Among them, 2mm≤D1≤5mm, 2mm≤D2≤5mm.

[0045] It should be noted that the third direction in the present application refers to Figure 4 Z direction, wherein the Z direction includes the direction indicated by the arrow or the opposite direction indicated by the arrow. Among them, the third direction is perpendicular to the first direction and the second direction.

[0046] It should be noted that the recess size of the first avoidance area 12 in the present application can be the same as the recess size of the second avoidance area 13, or it can be different, as long as the recess size D1 of the first avoidance area 12 is in the range of 2-5mm and the recess size D2 of the second avoidance area 13 is in the range of 2-5mm.

[0047] Next, referring to Figure 3 , the main body area 11 is provided with a plurality of adsorption holes 111, which can be connected with the vacuum device, so that when the vacuum device is started, it can generate strong suction through these adsorption holes 111. This suction can firmly hold the glass cover plate 2, making it tightly adhere to the film jig 1, thereby improving the stability of the glass cover plate 2 during the film coating process, ensuring that the glass cover plate 2 will not shift or shake during the film coating process, thereby ensuring the quality and effect of the film coating.

[0048] It should be noted that the present application does not limit the number and size of the adsorption holes 111, as long as it can generate suction under the action of the vacuum device to fix the glass cover plate 2 on the film jig 1.

[0049] Combined with Figures 3-5 , the process of using the film jig provided by the present application to coat the protective film on the glass cover plate 2 is as follows:

[0050] Place the glass cover plate 2 face up on the film jig 1 of the film coating machine, and during the placement process, the light transmission area 21 on the back of the glass cover plate 2 is aligned with the main body area 11 of the film jig 1, and the camera area 23 of the glass cover plate 2 is aligned with the second avoidance area 13 of the film jig 1, to avoid the problem of dirt on the light shielding area 22 and the camera area 23 due to contact with the film jig 1.

[0051] Then, the vacuum device of the film laminating machine is started to generate suction force at the suction holes 111 on the film laminating jig 1, so that the glass cover plate 2 is firmly adsorbed on the film laminating jig 1. After the glass cover plate 2 is fixed on the film laminating jig 1, the protective film is pasted on the front surface of the glass cover plate 2. After the pasting of the protective film is completed, the vacuum device is turned off, and the glass cover plate 2 is taken off from the film laminating jig 1.

[0052] The film laminating jig provided by the present application can improve the pasting efficiency and quality of the protective film on the glass cover plate 2, and the film laminating jig 1 of the present application can be repeatedly used for many times, greatly reducing the use cost, and the operation is simple.

[0053] In addition, the present application also provides a film laminating machine, which comprises the film laminating jig according to any of the above embodiments.

[0054] The film laminating jig is the same as described above, and will not be described here again.
