Abstract

This utility model discloses a screen panel bonding and assembly structure for an induction cooker, including a crystal plate and a screen panel. The bottom surface of the crystal plate has a pre-set bonding groove, and multiple insertion grooves for adhesive to penetrate are provided on both sides of the bonding groove. The screen panel includes a mounting base and a touch display screen. The top surface of the mounting base has an insert block for embedding into the bonding groove, and the mounting base has a cavity for accommodating the touch display screen. The top surface of the touch display screen is tightly attached to the bottom surface of the crystal plate. This application achieves precise alignment of the screen panel and prevents offset positioning by interlocking the insert block with the bonding groove. The depth of the bonding groove matches the height of the insert block, limiting the space for adhesive compression. Excess adhesive is absorbed by the insertion grooves, preventing the adhesive layer from squeezing and lifting the touch display screen. The adhesive in the insertion grooves forms a lateral adhesive layer, enhancing peel strength and ensuring that the touch display screen and the crystal plate are bonded together while strengthening their adhesion.

Description

Technical Field

[0001] This utility model relates to the field of induction cooker assembly, and in particular to a screen panel bonding assembly structure for induction cookers. Background Technology

[0002] Currently, most induction cooker touch screen panels are directly glued to the bottom of the crystal plate (microcrystalline glass panel).

[0003] Traditional assembly methods have two major drawbacks:

[0004] 1. Easy to misalign during bonding: The lack of a positioning structure leads to inaccurate alignment between the screen panel and the crystal plate;

[0005] 2. Touch abnormality: After the adhesive is applied, a thick layer is formed, which creates a gap between the touch display and the crystal board, causing the touch signal to attenuate or fail. Although there are solutions to set a bonding groove in the crystal board for positioning, the adhesive in the groove cannot be discharged after being pressed, and will still lift the screen panel, affecting the bonding between the touch display and the crystal board. Utility Model Content

[0006] The purpose of this invention is to provide a screen panel bonding and assembly structure for induction cookers to solve the above-mentioned problems.

[0007] According to one aspect of the present invention, a screen panel bonding assembly structure for use in an induction cooker is provided, comprising: a crystal plate and a screen panel, wherein the bottom surface of the crystal plate is provided with a bonding groove, and multiple penetration grooves for adhesive penetration are respectively provided on both sides of the bonding groove; the screen panel includes a fixing base and a touch display screen, wherein the top surface of the fixing base is provided with an embedding block for embedding into the bonding groove, and the fixing base is provided with a cavity for accommodating the touch display screen; the top surface of the touch display screen is tightly attached to the bottom surface of the crystal plate.

[0008] In some embodiments, the infiltration groove and the bonding groove are connected, and the infiltration grooves on both sides of the bonding groove are arranged in parallel.

[0009] In some embodiments, the infiltration groove and the bonding groove are connected, and the infiltration grooves on both sides of the bonding groove are staggered.

[0010] In some embodiments, the depth of the fitting groove is equal to the height of the embedding block.

[0011] In some embodiments, both the bonding groove and the infiltration groove have downward-facing openings.

[0012] In some embodiments, a flow guide angle is provided between the bonding groove and the penetration groove.

[0013] In some embodiments, the bottom surfaces of the fitting groove and the infiltration groove are both concave arc surfaces, and the top of the embedding block is a convex arc surface that matches the bottom surface of the fitting groove.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] This application achieves precise alignment of the screen panel and anti-offset positioning by interlocking the embedded block with the bonding groove; the depth of the bonding groove matches the height of the embedded block, limiting the space for adhesive compression, and excess adhesive is absorbed by the groove, preventing the adhesive layer from squeezing and lifting the touch screen. The adhesive that seeps into the groove forms a lateral adhesive layer, enhancing the peel strength and ensuring that the touch screen and the crystal board are bonded together while enhancing their adhesion.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] refer to Figures 1 to 5 This application provides a screen panel bonding assembly structure for use in an induction cooker, including: a crystal plate 1 and a screen panel 2. The bottom surface of the crystal plate 1 is provided with a bonding groove 3. Multiple penetration grooves 4 for glue penetration are respectively provided on both sides of the bonding groove 3. The screen panel 2 includes a fixing base 5 and a touch display screen 6. The top surface of the fixing base 5 is provided with an embedding block 7 for embedding into the bonding groove 3. The fixing base 5 is provided with a cavity 8 for accommodating the touch display screen 6. The top surface of the touch display screen 6 is tightly attached to the bottom surface of the crystal plate 1.

[0023] In some embodiments, the infiltration groove 4 is connected to the bonding groove 3, and the infiltration grooves 4 on both sides of the bonding groove 3 are arranged in parallel.

[0024] In some embodiments, the penetration groove 4 is connected to the bonding groove 3, and the penetration grooves 4 on both sides of the bonding groove 3 are staggered. The staggered penetration grooves 4 can make the glue enter the penetration grooves 4 on both sides more evenly when it overflows.

[0025] In some implementations, the depth of the fitting groove 3 is equal to the height of the embedded block 7.

[0026] In some embodiments, both the bonding groove 3 and the penetration groove 4 have downward-facing openings.

[0027] In some embodiments, a flow guide angle is provided between the bonding groove 3 and the penetration groove 4.

[0028] In some embodiments, the bottom surfaces of both the fitting groove 3 and the penetration groove 4 are concave arc surfaces, and the top of the embedding block 7 is a convex arc surface that matches the bottom surface of the fitting groove 3.

[0029] Example 1: A bonding groove 3 with a depth of 0.5mm is processed on the bottom surface of the crystal board 1. Penetration grooves 4 with a width of 0.2mm and a depth of 0.3mm are opened on both sides of the bonding groove 3 (parallel or staggered). A 45° guide angle is processed between the bonding groove 3 and the penetration groove 4. Adhesive is dotted into the bonding groove 3. The embedded block 7 of the screen panel 2 (with an adaptive curved surface processed on the top) is pressed into the bonding groove 3. Excess adhesive flows into the penetration grooves 4 on both sides along the guide angle. After filling, a lateral adhesive layer is formed. The top surface of the touch display screen 6 directly contacts the bottom surface of the crystal board 1 without the adhesive layer separating them.

[0030] This application achieves precise alignment of the screen panel 2 by engaging the embedded block 7 with the bonding groove 3, thus preventing offset positioning. The depth of the bonding groove 3 matches the height of the embedded block 7, limiting the space for adhesive compression. Excess adhesive is absorbed by the groove 4, preventing the adhesive layer from squeezing and lifting the touch display screen 6. The adhesive that seeps into the groove 4 forms a lateral adhesive layer, enhancing the peel strength and ensuring that the touch display screen 6 is bonded to the crystal plate 1 while enhancing its bonding firmness.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
