Description

Technical Field

[0001] The utility model belongs to the technical field of touch screens, and in particular relates to a double-sided adhesive splicing structure for a touch screen to be attached to a casing. Background Art

[0002] Due to the rapid development of smart terminals, many home appliances and industrial control equipment use touch screens. Due to different weather, temperature, humidity and power grid environments, they may be injured by static electricity from the human body, resulting in black screens, flashing screens and touch failures. It is often the case that machines and equipment are damaged by static electricity in dry weather after being used for a period of time, leading to returns. Currently, large-size touch screens use traditional double-sided tape design, which basically uses 4 double-sided tapes in an L-shape or a Z-shape to complete the assembly of the touch screen and the casing. This splicing method is short in path and single in direction, so it is easy for static electricity to enter the product and damage circuit components, resulting in product touch failure and display failure. Utility Model Content

[0003] The utility model aims to provide a double-sided adhesive splicing structure for bonding a touch screen to a housing, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-sided tape splicing structure for bonding a touch screen to a casing, comprising a casing, wherein the casing is bonded to one end of double-sided tape 1, double-sided tape 2, double-sided tape 3 and double-sided tape 4, and the other ends of double-sided tape 1, double-sided tape 2, double-sided tape 3 and double-sided tape 4 are bonded to the touch screen, and both ends of double-sided tape 1 and double-sided tape 3 are respectively provided with a boss, and both ends of double-sided tape 2 and double-sided tape 4 are respectively provided with a groove, and the boss and the groove match each other.

[0005] Technical effects and advantages of the utility model: The utility model improves the double-sided adhesive tape, namely, increases bosses and grooves, and changes the shape of the joints to a socket shape, thereby extending the path and direction for static electricity to enter, preventing static electricity from directly entering the product, and effectively avoiding and reducing ESD damage to products.

[0011] In the picture: 100 double-sided tape 1, 110 double-sided tape 2, 120 double-sided tape 3, 130 double-sided tape 4, 200 boss, 300 groove, 400 casing. DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] The utility model provides Figure 1-5 A double-sided tape splicing structure for bonding a touch screen to a casing shown in the figure includes a casing, wherein the casing 400 is bonded to one end of double-sided tape 100, double-sided tape 2 110, double-sided tape 3 120 and double-sided tape 4 130, and the other ends of double-sided tape 100, double-sided tape 2 110, double-sided tape 3 120 and double-sided tape 4 130 are bonded to the touch screen, and a boss 200 is respectively provided at both ends of the double-sided tape 100 and the double-sided tape 3 120, and a groove 300 is respectively provided at both ends of the double-sided tape 2 110 and the double-sided tape 4 130, and the boss 200 matches the groove 300.

[0014] Working principle:

[0015] During operation, one end of double-sided tape 100, double-sided tape 2 110, double-sided tape 3 120 and double-sided tape 4 130 are adhered to the housing 400 in sequence, wherein the boss 200 and the groove 300 at the interface are aligned with each other, and then the touch screen is adhered. The setting of the boss 200 and the groove 300 changes a horizontal line at the original joint, increases the path length and changes the direction, and effectively avoids and reduces ESD static electricity damage to the product.

[0016] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
