S4: Fixedly connect the cover plate 22 and the decorative part 24 .

In this way, when manufacturing the cover plate assembly 20, one sheet 10 is used to install one cover plate assembly 20, so that when producing the cover plate assembly 20, it is easy to operate the sheet 10 to realize the production of a certain cover plate assembly 20 individually Operation, the production processes of different cover plate assemblies 20 will not affect each other, which improves the production efficiency of the cover plate assembly 20 .

It can be understood that in the production process of the cover plate assembly 20, when multiple cover plate assemblies 20 share a sheet 10, it is difficult to perform immediate operations on the production process of a single cover plate assembly 20. In the operation of flipping the sheet 10 after dispensing glue on the board assembly 20, after dispensing glue on multiple cover assemblies 20, it is necessary to wait for the glue on all the cover assemblies 20 to be cured before flipping the sheet 10, and during this period, The cover plate assembly 20 that has been glued first has already met the conditions for turning over, but cannot immediately enter the next manufacturing process. In the embodiment of the present invention, a cover assembly 20 is installed on a sheet 10, which is convenient for immediately entering subsequent production operations according to the condition of the cover assembly 20, and improves the flexibility and production efficiency when producing the cover assembly 20.

Specifically, the cover plate 22 may be made of light-transmitting materials such as glass, ceramics, or sapphire, so that the user can view the content displayed on the display screen of the electronic device through the cover plate 22 . At the same time, the cover plate 22 can be used as an appearance part of the electronic device. The cover plate 22 is vulnerable to collision or scratches. Therefore, the cover plate 22 can be made of a material with relatively high hardness, such as the aforementioned sapphire.

It can be understood that the shape of the cover plate 22 can be specifically designed according to the shape of the electronic device, such as rounded rectangle, circle, ellipse and other shapes. The cover plate through hole 222 can be provided on the edge of the cover plate 22 close to the cover plate 22. The cover plate through hole 222 can be formed after cutting the complete cover plate 22, or can be formed when the cover plate 22 is integrally formed. , the shape of the through hole 222 of the cover plate may be a rounded rectangle, a circle, a racetrack shape and the like.

In some embodiments, the size of the sheet 10 is smaller than the size of the cover plate 22 .

In this way, the material used for manufacturing the sheet 10 is saved, and at the same time the volume of the sheet 10 is small, and it is easy to perform subsequent operations on the sheet 10, such as clamping and turning over. Of course, according to different actual production requirements, the size of the sheet 10 may also be equal to or larger than the size of the cover plate 22 . In one embodiment, a portion of the sheet 10 protrudes from the edge of the cover plate 22 to facilitate manipulation of the sheet 10 by gripping the protruding portion of the sheet 10 .

2 and 3, in some embodiments, the cover plate 22 includes a first surface 224 and a second surface 226 opposite to each other, and the cover plate through hole 222 runs through the first surface 224 and the second surface 226, and the cover plate The edge where the through hole 222 meets the first surface 224 is formed with a chamfer 228, and the step S3 includes a step S31: relatively moving the cover plate 22 and the decoration 24, so that the decoration 24 moves from the first surface 224 to the second surface 226 The direction is installed in the through hole 222 of the cover plate and the outer wall of the decoration part 24 is against the chamfer 228 .

In this way, when installing the cover plate 22 , the through hole 222 of the cover plate is aligned with the decorative part 24 , and the chamfer 228 facilitates guiding the decorative part 24 to move relative to the cover plate 22 and be installed in the through hole 222 of the cover plate.

Specifically, the decoration 24 includes a base ring 242 and a resisting wall 244 . The resisting wall 244 extends outward from the top of the base ring 242 , and the resisting wall 244 includes a resisting surface 2442 connected to the outer surface of the base ring 242 and forming an obtuse angle with the outer surface. When the cover plate 22 is installed, relatively move the cover plate 22 and the decorative part 24, so that the decorative part 24 penetrates the cover plate through hole 222 from the first surface 224, and further makes the cover plate 22 or the decorative part 24 close until the chamfer When 228 abuts against the abutting surface 2442, it indicates that the decorative part 24 is completely installed in the through hole 222 of the cover plate, that is, the installation of the cover plate 22 is completed.

When using the cover plate assembly 20, the second surface 226 can be a surface that is attached to the display screen of the electronic device, and the light emitted by the display screen passes through the second surface 226 and the first surface 224 successively and then exits the electronic device. In an embodiment, the user can also manipulate the electronic device by touching the first surface 224 .

Referring to FIG. 2 and FIG. 4 , in some embodiments, step S3 includes step S32 : combining the first surface 224 with the base surface 12 .

Specifically, the combination of the first surface 224 and the base surface 12 may be that the first surface 224 is attached to the base surface 12 but not connected, or may be a detachable connection between the first surface 224 and the base surface 12, for example, the first surface 224 is attached to the base surface 12, and then the first surface 224 and the base surface 12 are adhered to each other under atmospheric pressure by extracting the air between the first surface 224 and the base surface 12; Face 12 clamping etc.

It can be understood that, since the top block 14 is arranged on the base surface 12, when the first surface 224 is combined with the base surface 12, the top block 14 is always against the decorative part 24 and the top block 14 pushes the decorative part 24 to and from the first surface. 224 abuts against the second surface 226 to ensure that the abutting surface 2442 abuts against the chamfer 228 .

Preferably, in some embodiments, the material of the top block 14 is one or more of TPU (thermoplastic polyurethane elastomer), rubber, and silicone. In this way, the elasticity of the top block 14 is better. When the first surface 224 is combined with the base surface 12, the top block 14 is pressed against the decorative part 24 and the top block 14 undergoes a certain deformation. Specifically, the top block 14 is compressed between the base surface 12 and the decorative part 24, so that The top block 14 can always apply a resisting force to the decoration part 24 to better keep the decoration part 24 in the through hole 222 of the cover plate.

5 and 6, in some embodiments, the base surface 12 includes a pressing portion 122 corresponding to the through hole 222 of the cover plate and a joint portion 124 surrounding the periphery of the pressing portion 122, and the top block 14 is arranged on the pressing portion 122. On the pressing part 122 , the combining part 124 and the pressing part 122 form a height difference. Step S3 includes step S33 : combining the first surface 224 with the combining part 124 , and forming a height difference between the first surface 224 and the pressing part 122 .

Specifically, the sheet 10 can be in the shape of a flat plate, and the sheet 10 can be bent first so that the joint portion 124 and the pressing portion 122 form a certain height difference. It can be understood that after the sheet 10 is bent, the sheet 10 will There is a tendency to return to its original shape, that is, the pressing portion 122 has a tendency to restore the deformation by the elasticity of the sheet 10 . In some embodiments, the material of the sheet 10 is one or both of PC (polycarbonate) and PET (polyethylene terephthalate). In order to make the sheet material 10 have better rebound performance after being deformed, that is, the sheet material 10 can be better restored to its original shape.

Further, the first surface 224 and the pressing part 122 form a height difference, and the first surface 224 is combined with the joint part 124 and the top block 14 is arranged on the pressing part 122, so that the sheet 10 tries to reduce the pressure under the action of elasticity. When the height difference between the pressure-applying part 122 and the joint part 124 is small, the pressure-applying part 122 exerts a certain pressure on the top block 14, and makes the top block 14 have a greater resistance to the decorative part 24 so that the decorative part 24 and the inverted Angle 228 resists more tightly.

Referring to Fig. 2 and Fig. 7, in some embodiments, the decorative part 24 is formed with a decorative part through hole 248, and the decorative part 24 includes a bearing part 246, and the bearing part 246 is from the inner wall of the decorative part through hole 248 to the decorative part through hole. 248 , the step S2 includes step S21 : align the through hole 248 of the decorative part with the top block 14 and make the top block 14 abut against the supporting portion 246 .

Specifically, the base ring 242 surrounds the decoration through hole 248, and the bearing part 246 extends from the bottom of the base ring 242 to the center of the decoration through hole 248. In actual use, a fingerprint identification module, etc. can be installed in the decoration through hole 248 and carried on the bearing part 246. The top block 14 protrudes into the through hole 248 of the decoration part and the outer wall of the top block 14 is in contact with the inner wall of the decoration part 24 , so that the relative sliding between the top block 14 and the decoration part 24 is not easy to occur. In the embodiment of the present invention, the through hole 248 of the decorative part is opened in the middle of the decorative part 24, the center of the bearing part 246 coincides with the central axis of the through hole 248 of the decorative part, and the pressure exerted by the top block 14 on the bearing part 246 is relatively uniform. In order to make the abutting surface 2442 and the chamfer 228 fit well at each position.

Referring to FIG. 2 and FIG. 8 , in some embodiments, step S4 includes step S41 : injecting glue 30 from the second surface 226 into the gap between the outer wall of the decoration part 24 and the inner wall of the through hole 222 of the cover plate.

Specifically, when the cover plate 22 and the decorative part 24 are supported on the sheet 10, the chamfer 228 is against the outer wall of the decorative part 24, and the sealing between the chamfered corner 228 and the outer wall of the decorative part 24 is better, and the cover plate can pass through. A gap is formed between the inner wall of the hole 222 and the outer wall of the decorative part 24, and glue 30 is injected into the gap. On the one hand, the decorative part 24 and the cover plate 22 can be fixedly connected, and on the other hand, the outer wall of the decorative part 24 and the cover plate can be filled. The gap between the through holes 222 prevents relative movement of the decorative part 24 and the cover plate 22 in subsequent use.
