[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Example 1

[0034] like Figures 1-3 The image shows a glue injection device for a 3C screen in this embodiment. At least one glue inlet 10 is provided on the glass 1 of the 3C screen. The glue inlet 10 is used to inject glue into the processing area. The glue injection device includes a plate 2 formed by printing and having a glue channel groove 20 on any surface in the thickness direction. The glass 1 to be glued covers the surface of the plate 2 with the glue channel groove 20, and a sealant molding cavity is formed between the groove of the glue channel groove 20 and the glass 1. The sealant molding cavity is connected to the glue inlet 10. At the same time, the plate 2 is a honeycomb plate, which is beneficial for weight reduction and improving overall rigidity. At least a release coating 21 is provided in the glue channel groove 20.

[0035] The aforementioned honeycomb panel structure design possesses high strength and rigidity, along with good thermal stability, meeting the requirements for high-precision adhesive injection. In this embodiment, the panel 2 is fabricated using 3D printing technology, offering advantages such as rapid prototyping, the ability to manufacture complex structures, and personalized customization. Figures 10-11 As shown, a release coating 21 is provided on the surface of the glue runner 20. This release coating 21 can not only effectively prevent the glue from sticking to the glue runner 20, but also significantly reduce the frictional resistance generated by the glue during the flow process, thereby further improving the glue injection efficiency and molding accuracy.

[0036] In addition, such as Figures 8-9As shown, on one surface of the plate 2 where the adhesive channel 20 is provided, there are also several shallow adhesive grooves 22 communicating with the adhesive channel 20. Each shallow adhesive groove 22 is connected to a separate adhesive inlet 10, ensuring that the adhesive can accurately enter the back of the glass 1 from a specific position. The depth of the shallow adhesive groove 22 is less than the depth of the adhesive channel 20. This design allows the adhesive to uniformly and stably cover and fill the adhesive channel 20. The design of the shallow adhesive grooves 22 can also be flexibly adjusted according to specific product requirements. For example, in 3C screens of different sizes, different sealing requirements can be adapted by changing the number, spacing, and depth of the shallow adhesive grooves 22.

[0037] Specifically, such as Figure 5 As shown, there are two shallow adhesive grooves 22, distributed at the two oblique corners of the plate 2. This design can achieve a balanced distribution of adhesive during the adhesive injection process, avoiding uneven sealing caused by too much or too little adhesive on one side.

[0038] In addition, such as Figure 1 The glue-dispensing device also includes a pressure block 3 covering at least a portion of the surface of one end of the glass 1, and a sealing nozzle 30 on the pressure block 3 communicating with the glue outlet 10. The sealing nozzle 30 seals the outer opening of the glue outlet 10. Simultaneously, a syringe 4 is inserted into the sealing nozzle 30 to supply glue for processing. The syringe 4 can also control its pressure to change its glue-dispensing rate. Furthermore, to ensure a stable glue supply, the syringe 4 and the sealing nozzle 30 are connected in a well-sealed manner to prevent glue leakage or air bubble generation during injection.

[0039] like Figure 4 As shown, a plurality of recessed grooves 31 are provided on the surface of the pressure block 3 near the glass 1, which are recessed away from the glass 1. A column 32 with a through hole 11 extending through the glass 1 is provided at the bottom of each recessed groove 31. Specifically, a column 32 is provided at the bottom of each recessed groove 31, and the column 32 is a conical column. Figures 6-7 As shown, the outer diameter of the column 32 is smaller than the diameter of the through hole 11, and the column 32 abuts against the bottom of the adhesive channel 20. This is to allow the adhesive to flow from the through hole 11 into the recessed groove 31, enabling the adhesive to simultaneously adhere to both sides of the glass 1. This design allows the plate 2, glass 1, and pressure block 3 to together form several I-shaped spaces. When the adhesive is injected into these spaces, after solidification, it forms a columnar I-shaped plastic part that penetrates both sides of the glass 1, resulting in better fixation between the molded plastic part and the glass 1. Simultaneously, due to the presence of the column 32, the I-shaped plastic part will form... Figures 12-13 The through hole shown is designed to facilitate the quicker detachment of the pressure block 3 from the glass 1 after processing, without damaging the plastic part fixed to the glass.

[0040] Regarding fixed aspects, such as Figure 2 As shown, plate 2 is fixed to base plate 5. Plate 2 is connected to pressing members S, which press against at least a portion of the surface of glass 1, via a detachable structure. There are several pressing members S. At least a portion of the pressing members S pass through the pressing block 3, glass 1, and plate 2 in sequence and are connected to base plate 5 via a detachable structure. The remaining pressing members S pass through glass 1 and plate 2 in sequence and are connected to base plate 5 via a detachable structure. The pressing members S are designed with bolts or other adjustable fasteners, and the pressing force can be adjusted by rotation or other means. In addition, in order to ensure that excessive pressure or deformation is not caused to glass 1 during the fixing process, the pressing members S in this embodiment are equipped with shock-absorbing pads or buffers to disperse pressure and protect the surface of glass 1.

[0041] Meanwhile, as a practical design, the pressure block 3 is provided with a hollow hole 33 at least in part of the adhesive flow channel 20. Since the glass 1 in this embodiment is a tempered glass with high light transmittance, it improves the UV light penetration and LSR curing stability. The operator can observe the adhesive injection situation at the recessed groove 31 through the hollow hole 33 to ensure the quality of the finished product in each processing operation.

[0042] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
