Further, an embodiment of the present application further provides a method for assembling a protection component, referring to fig. 10, fig. 10 is a schematic flow chart of an embodiment of the method for assembling a protection component. The assembly method includes, but is not limited to, the following steps.

In step S100, a decoration is provided.

The structure of the decoration (especially the structure of the glue groove) is as described in the previous embodiment, and will not be described here again.

In step S200, the decoration is placed on the centrifugal turntable, so that the decoration can rotate along with the centrifugal turntable.

In step S200, the direction of the centrifugal force of the centrifugal turntable is the same as the depth direction of the decorative piece glue groove. Assuming that the centrifugal rotor is a horizontal rotor, the direction of the centrifugal force is the arrow X direction in fig. 8.

And step S300, dispensing glue into the glue groove of the rotating decoration piece.

The glue dispensing head also rotates along with the centrifugal turntable, and the glue can outwards fly under the action of the centrifugal force, fall into the glue groove and stay in the glue groove.

Step S400, the lens is adhered to the decoration through glue in the glue groove.

Wherein, the glue can be selected from the glue with lower viscosity less than 5000 and lower thixotropic property less than 2. The bubbles are not easy to be in the glue, just like the bubbles can float upwards in the water to be discharged, or the bubbles can be extracted from the glue by adopting a deaeration machine. Because glue viscosity is little and glue overflows easily, consequently put the decoration on centrifugal carousel point gum, after the centrifugal carousel is rotatory, spun glue pearl can get rid of the gluey inslot of decoration owing to centrifugal force, can not overflow everywhere. Then, assembling the lens on a rotary machine, starting UV light irradiation curing for 30s-60s, stopping rotation, and taking down the product.

Optionally, please continue to refer to fig. 1, in the related art, in order to ensure the adhesion and air tightness of the lens 1, the glue amount of the dispensing is as large as possible, so that after the lens 1 is assembled, the glue 1d of the glue groove is extruded and overflows, the thixotropic property and viscosity of the glue are higher, the glue cannot self-level, the glue 1d is extruded to the appearance gap 1e through the lens 1, the surface of the glue is rough, and the quality appearance inspection is determined as poor appearance, thereby affecting the user experience. Referring to fig. 1, reference numeral 1f in fig. 1 is a structure in which the glue surface is easily wavy after the glue is squeezed into the appearance gap by the lens in the related art.

In view of this, referring to fig. 11, fig. 11 is a schematic sectional view of a part of a structure of another embodiment of the decoration of the present application, and the bottom wall 1231 of the glue groove 123 is further provided with a glue overflow groove 125, where the glue overflow groove 125 is disposed adjacent to the second side wall 12322. Referring to fig. 12, fig. 12 is a schematic structural diagram of the ornament and the lens in the embodiment of fig. 11, wherein the dimensions of the glue groove 123 and the glue overflow groove 125 are as follows: the height h of the recommended glue overflow groove is 0.15-0.25mm; the depth i of the glue overflow groove is recommended to be 0.1-0.2mm; the effective bonding height j is recommended to be 0.4-0.5mm; the proposed glue thickness k is designed to be 0.12mm, and the actual glue thickness may be 0.1-0.2mm.

In the decoration structure of this embodiment, a deeper glue overflow groove is formed at the upper end of the glue groove, so as to accommodate more glue 103, so that the glue 103 does not enter the appearance gap 106, and further, the glue is prevented from overflowing, and the appearance is affected. Referring to fig. 13, fig. 13 is a schematic view of the dispensing structure of the decoration in fig. 11, wherein the glue 103 does not enter the glue overflow groove 125 during the dispensing process. When the lens 140 is assembled, the glue 103 is extruded, and the glue 103 floats upwards to enter the glue overflow groove 125 (as shown in fig. 12), but cannot enter the appearance gap 106, so that the appearance problem caused by the fact that the glue 103 is waved and fluctuated in the slit is avoided. It should be noted that all directional indicators (such as up, down, left, right, front, and rear … …) in the embodiments of the present application are merely used to explain the relative positional relationship, movement conditions, and the like between the components in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is correspondingly changed.

According to the decoration structure in the embodiment, the deeper glue overflow groove is formed in the upper end of the glue groove, so that the problem that glue overflows into an appearance gap to cause rough appearance of a glue path can be avoided, and the appearance yield of production line production is improved.

Optionally, in some other embodiments, a vibration module may be further added to the lens assembling device, and after the lens is assembled, vibration is performed on the sample for a period of time, so that the uneven glue surface is leveled under the action of external force, and the glue surface is changed into a smooth and flat state.

With continued reference to fig. 1, in the related art, the bottom surface of the lens 1 is supported by the step surface 1g of the decoration 4, and the lens is zero-matched with the supporting step surface 1g of the decoration, so that the step surface 1g has no glue, which is not beneficial to waterproof and adhesive strength. In order to ensure enough adhesive force, the adhesive dispensing amount of the adhesive slot is large, and some adhesive remains on the step surface 1g of the lens after the adhesive is dispensed. When the lens is pressed down to extrude the glue, a part of the glue overflows inwards, so that a circle of glue (the mark 1h in the figure) is arranged on the inner side of the step surface 1g of the lens, and uneven glue overflow and overlarge glue overflow can exist to cause poor appearance.

In view of this, the embodiment of the present application further provides a structure of a decoration, please refer to fig. 14, fig. 14 is a schematic structural diagram of another embodiment of the decoration of the present application, an inner side wall of the decoration 120 is further provided with a supporting surface 126, the supporting surface 126 is coplanar with a side wall (a first side wall 12321 in the present embodiment) of the glue groove 123, and a junction area between a side surface of the lens 140 and the bottom surface 142 of the lens abuts against the supporting surface 126, which may specifically be a linear contact, so that a glue overflow gap 104 is formed between the bottom surface 142 of the lens 140 and the supporting surface 126. In the decoration structure of this embodiment, the supporting surface 126 of the lens 140 is made into an inclined surface, so that the lens 140 and the decoration 120 can be in line contact (instead of the conventional overlap joint between the bottom surface 142 of the lens 140 and the supporting surface 126), and other positions can be filled with glue, so as to improve the bonding area and the bonding strength. The reserved glue overflow gap 104 is used for storing overflowed glue, and appearance is not affected.

With continued reference to fig. 14, the dimensions of the support surface 126 of the trim piece 120 are as follows: suggesting that l is 0.05-0.1mm; suggesting that m is 0.25-0.4mm; the proposed angle n is 30 ° -45 °. Referring to fig. 15, fig. 15 is a schematic diagram of the structure of the decoration piece and the lens in fig. 14, after assembling the lens, the glue 1033 overflowing from the inner side is filled in the included angle between the lens 140 and the decoration piece 120, and the contact area between the glue 1033 and the structural member in the included angle is large, so that the glue overflowing is not easy to flow locally.
