Description

Technical Field

[0001] The present invention belongs to the field of molds, and in particular relates to a glue injection device and a glue injection method for a 3C screen. Background Art

[0002] In the existing technology, existing process mold production faces three significant problems: high manufacturing costs, long production cycles, and high costs of failure. First, high manufacturing costs are mainly reflected in high material consumption, low single-piece production efficiency, complex design and manufacturing processes, and over-reliance on experience. These factors are combined, resulting in each design modification requiring a large amount of resources, further driving up costs. In addition, the production cycle is complicated by the complex development process, suboptimal design solutions, difficult processing, and cumbersome debugging. These links are intertwined, resulting in frequent delays in the entire development process, seriously affecting production efficiency. Problems that arise during production require the redesign or remanufacturing of molds, which not only increases costs but also further extends the production cycle, forming a vicious cycle. Summary of the Invention

[0003] The purpose of the present invention is to provide a glue injection device and a glue injection method for a 3C screen that can solve the above technical problems.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

The glass to be injected with glue is covered on a surface of the plate body provided with the glue flow groove, and a sealant molding cavity is formed between the groove opening of the glue flow groove and the glass, and the sealant molding cavity is connected to the glue opening.

[0006] Furthermore, the plate body is a honeycomb plate body, and a release coating is provided at least in the glue runner groove.

[0008] Furthermore, there are two shallow glue grooves and they are distributed at two oblique angles of the plate body.

[0009] Furthermore, the glue injection device also includes a pressing block covering at least a portion of the surface of one end of the glass, and a sealing nozzle connected to the glue port is provided on the pressing block, and the sealing nozzle is sealed with the outer opening of the glue port. The glue injection device also includes a syringe at least partially inserted into the sealing nozzle.

[0010] Furthermore, a recessed groove is provided on a surface of the pressure block near the glass, recessed away from the glass. A column is provided at the bottom of the recessed groove, extending through a through hole provided in the glass. The outer diameter of the column is smaller than the diameter of the through hole, and the column abuts against the bottom of the glue runner groove. The two are in surface-to-surface contact.

[0011] Furthermore, a plurality of the concave grooves are provided on a surface of the pressing block, and a column is provided at the bottom of each of the concave grooves, and the column is a conical column.

[0012] Furthermore, the plate body is fixed to the base plate, and the plate body is connected to a pressing member that is pressed against at least part of the surface of the glass through a detachable structure. There are several pressing members, and at least part of the several pressing members sequentially penetrate the pressure block, the glass and the plate body and are connected to the base plate through the detachable structure. The remaining pressing members sequentially penetrate the glass and the plate body and are connected to the base plate through the detachable structure.

[0013] As an application solution, the present application further provides a method for injecting glue into a 3C screen, using the aforementioned 3C screen injecting glue device. The method comprises the following steps:

[0014] S1. Covering the glue-injected glass on a surface of the plate body provided with a glue flow channel, and forming a sealant molding cavity between the glass and the glue flow channel;

[0015] S2. Liquid silicone is injected into the sealant molding cavity through the glue port reserved on the glass in S1, and the liquid silicone is cured and molded in the sealant molding cavity at a temperature of 30 degrees Celsius to 40 degrees Celsius to obtain the glass with the liquid silicone curing component.

[0016] Furthermore, before the above-mentioned step S1, the process further includes at least a step of manufacturing the plate body by 3D printing. The specific processing steps of the plate body are as follows:

DETAILED DESCRIPTION

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0036] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0037] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0038] In the description of this embodiment, terms such as "upper," "lower," "right," and "left" are used to refer to positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0039] Example 1, as Figure 1-Figure 3 The figure shows the glue injection device of the 3C screen in this embodiment. At least one glue port 10 is reserved on the glass 1 of the 3C screen. The glue port 10 is used to inject glue into the processing area, and the above-mentioned glue injection device includes a plate body 2 formed by printing and having a glue flow groove 20 on any surface in the thickness direction. The glass 1 to be injected with glue covers a surface of the plate body 2 provided with the glue flow groove 20 and a sealant molding cavity is formed between the groove of the glue flow groove 20 and the glass 1. The sealant molding cavity is connected to the glue port 10. At the same time, the above-mentioned plate body 2 is a honeycomb plate body, which is conducive to weight reduction and improving overall rigidity, and a release coating 21 is provided at least in the glue flow groove 20.

[0040] The structural design of the honeycomb panel has high strength and rigidity, and good thermal stability, which can meet the needs of high-precision glue injection. In this embodiment, the panel 2 is made by 3D printing technology, which has the advantages of rapid prototyping, complex structure manufacturing, and personalized customization. Figure 10-11 As shown, a release coating 21 is provided on the surface of the glue runner groove 20. This release coating 21 can not only effectively prevent the glue from sticking to the glue runner groove 20, but also significantly reduce the friction resistance generated by the glue during the flow process, thereby further improving the glue injection efficiency and molding accuracy.

[0041] In addition, if Figure 8-Figure 9 As shown, the surface of the plate 2 having the glue flow channel 20 also has a plurality of shallow glue grooves 22 connected to the glue flow channel 20. Each shallow glue groove 22 is connected to a separate glue port 10, ensuring that the glue can accurately enter the back of the glass 1 from a specific location. The groove depth of the shallow glue groove 22 is less than the groove depth of the glue flow channel 20. This design allows the glue to evenly and stably cover and fill the aforementioned glue flow channel 20. The design of the shallow glue groove 22 can also be flexibly adjusted according to specific product requirements. For example, in 3C screens of different sizes, the number, spacing, and groove depth of the shallow glue grooves 22 can be adjusted to meet different sealing requirements.

[0042] Specifically, if Figure 5 There are two shallow glue grooves 22 and they are distributed at two oblique corners of the plate 2. This design can achieve balanced distribution of glue during the glue injection process, avoiding uneven sealing caused by excessive or insufficient glue on one side.

[0043] In addition, if Figure 1The illustrated glue injection device also includes a pressure block 3 that covers at least a portion of one end of the glass 1. A sealing nozzle 30 is provided on the pressure block 3 and communicates with the glue port 10. The sealing nozzle 30 is sealed against the outer opening of the glue port 10. A syringe 4 is inserted into the sealing nozzle 30 to provide glue for processing. The syringe 4 can also control its pressure to vary its injection rate. Furthermore, to ensure a stable supply of glue, a well-sealed connection is employed between the syringe 4 and the sealing nozzle 30 to prevent leakage or bubbles during the injection process.

[0044] like Figure 4 As shown, a plurality of recessed grooves 31 are provided on a surface of the pressing block 3 close to the glass 1 and recessed toward the side away from the glass 1, and columns 32 are provided at the bottom of the recessed grooves 31 and penetrate the through hole 11 provided on the glass 1. Specifically, a column 32 is provided at the bottom of each recessed groove 31, and the column 32 is a conical cylinder. Figure 6-Figure 7 As shown, the outer diameter of the column 32 is smaller than the aperture of the through hole 11 and the column 32 abuts against the bottom of the glue flow channel 20, the purpose of which is to allow the glue to flow from the through hole 11 into the recessed groove 31, so that the glue can adhere to both sides of the glass 1 at the same time. This design allows the plate 2, the glass 1 and the pressing block 3 to form a number of "I"-shaped spaces together. When the glue is injected into this part, after the glue solidifies, a columnar "I"-shaped plastic part will be formed and pass through both sides of the glass 1, so that the molded plastic part and the glass 1 have a better fixing effect. At the same time, due to the presence of the column 32, the "I"-shaped plastic part will form a space similar to the Chinese character "I". Figure 12-13 The through hole shown is used to facilitate the above-mentioned pressing block 3 to be separated from the glass 1 more quickly after processing is completed without causing damage to the above-mentioned plastic parts fixed on the glass.

[0045] Regarding fixed aspects, such as Figure 2 As shown, the plate body 2 is fixed to the base plate 5. The plate body 2 is connected to a pressing member 34 through a detachable structure, which is pressed against at least part of the surface of the glass 1. There are several pressing members 34. At least some of the pressing members 34 sequentially penetrate the pressure block 3, the glass 1, and the plate body 2 and are connected to the base plate 5 through the detachable structure. The remaining pressing members 34 sequentially penetrate the glass 1 and the plate body 2 and are connected to the base plate 5 through the detachable structure. The design of the pressing members 34 uses bolts or other adjustable fasteners, and the pressing force can be adjusted by rotation or other means. In addition, to ensure that the glass 1 is not subjected to excessive pressure or deformation during the fixing process, the pressing members 34 in this embodiment are equipped with shock-absorbing pads or buffers to disperse the pressure and protect the surface of the glass 1.

[0046] At the same time, as a practical design, the pressing block 3 is provided with a hollow hole 33 corresponding to at least a portion of the glue flow channel 20. Since in this embodiment, the glass 1 is a tempered glass with high light transmittance, the UV light penetration is improved and the LSR curing stability is improved. The operator observes the glue injection situation at the above-mentioned recessed groove 31 through the above-mentioned hollow hole 33 to ensure the quality of the finished product of each processing operation.

[0047] Example 2: The structure and principle of this embodiment are basically the same as those of Example 1. The different structure is that, for the glue injection device of the 3C screen in the above-mentioned Example 1, this embodiment describes the glue injection method for the above-mentioned 3C screen.

[0048] The above-mentioned glue injection method comprises the following steps:

[0049] S1. Cover the glass 1 to be injected with glue on a surface of the plate 2 provided with the glue flow channel 20, and press and fix the two and other remaining plate components through the pressing member 34, so that a sealant molding cavity is formed between the glass 1 and the glue flow channel 20; a layer of contoured silicone base film is provided on the surface of the glass 1 to be injected with glue, and the silicone base film, such as PET, can protect the glass 1.

[0050] S2, injecting liquid silicone into the sealant molding cavity at low pressure and low speed through the glue port 10 reserved on the glass 1 in S1, and curing the liquid silicone in the sealant molding cavity at a temperature of 30 degrees Celsius to 40 degrees Celsius (for 1 hour) to obtain Figure 12 The glass 1 with the liquid silicone cured component 6 is shown.

[0051] In particular, before the above-mentioned S1 step, it also includes at least a step of preparing the plate body 2. In this embodiment, the above-mentioned plate body 2 is first prepared into a semi-processed part by 3D printing technology, and then the semi-processed floor body 2 is cleaned; finally, a release coating 21 is provided on at least the glue flow channel groove 20 of the plate body 2 processed by S11, that is, the plate body 2 is prepared; specifically, regarding the above-mentioned release coating 21, in this embodiment, the release coating 21 is prepared by PCV (magnetron sputtering) / CVD (chemical vapor deposition) / Parylene (vacuum vapor deposition) or a combination.

After setting the printing parameters, start the printing process. The 3D digital model of the mold is solidified layer by layer into a solid body through light-curing technology. This step includes the following sub-steps:

[0058] Step 201: Import the printing instruction file into the light-curing 3D printer;

[0060] Step 203: Start the printer and cure the photosensitive resin layer by layer according to the instruction file to produce the plate 2;

[0061] Step 3: Determine the print quality, perform visual inspection and dimensional measurement on the printed board 2 to check whether its surface quality, dimensional accuracy and structural integrity meet the design requirements. If unqualified, return to step 1 to re-model and print. If qualified, proceed to step 4;

[0062] Step 4: Post-printing processing: Perform subsequent processing on the qualified printed board 2, such as removing support structures, polishing, coloring, etc., to make it meet the requirements for use. This step includes the following sub-steps:
