Description

Technical Field

[0001] The utility model relates to a tool for detecting bonding quality, in particular to a tool for detecting bonding quality of a gas water heater panel. Background Art

[0002] Figure 1 and Figure 2 This is a glass panel assembly 1a for a gas water heater in the prior art. The glass panel assembly 1a includes a stainless steel mask 11a and a glass plate 12a bonded to the front end of the stainless steel mask 11a. The spot welding assembly of the glass plate 12a and the stainless steel mask 11a is combined with silicone adhesive as an adhesive and then fixed to the tank body of the gas water heater with screws. A plurality of air holes 13a are arranged on the stainless steel mask 11a because silicone adhesive is used for bonding. The curing of silicone adhesive is water absorption curing, and the function of the air holes is to absorb moisture to produce curing moisture.

[0003] After the glass plate is bonded, it is mainly subjected to shear stress under the weight of the glass plate itself. In order to ensure that there is no debonding quality accident during the use of the product, the panel assembly must pass a variety of tests such as heat and humidity test, high and low temperature impact test, high temperature test, gravity shear test, etc. after bonding. It is required that after the above tests, the product has no debonding, the surface does not change color, the thickness of the glue layer is uniform, and the glass has no serious additional stress; in addition, the weight of the glass plate is only a few kilograms, and the shear stress of the bonding surface is not the main factor affecting the bonding strength of the product. The state where the glass is subjected to the greatest stress is the state when it is automatically packaged and boxed on the production line. Due to the large weight of the whole machine, the vacuum suction cup of the automatic boxing equipment is vertically adsorbed on the glass panel assembly during boxing, and the entire product is moved from the terminal of the assembly line to the packaging box. At this time, the bonding surface of the panel assembly bears the weight of the entire product, so the tensile strength of the bonding surface can be used as the basis for process design and glue line path layout.

[0004] The current method for measuring the tensile strength of the bonding surface is to hang an iron block of corresponding weight during the development stage. This method has no accurate data support, and the force mode is inconsistent with the production line; on the other hand, this method cannot be applied in production, so it needs to be improved.
