Problems solved by technology

However, after the above process, there is still residual glue on the glass and metal parts, which affects the quality of the product, and eventually leads to the scrapping of each component, resulting in serious waste; and it is necessary to re-make the coating and ink on each component, which increases the investment. cost

Embodiment 1

[0031] In the process of removing glue and reusing the assembly provided in this example, the heating plate heats the entire assembly, specifically, the temperature of the heating plate is 190°C, and the heating time is 1.5 minutes; then the heated assembly is disassembled, and the Put the dismantled glass substrate with residual glue into the soaking tank for 1 hour, and the temperature of the soaking liquid is at room temperature; put the metal parts with the residual glue into another soaking tank for 5 minutes, and soak at a temperature of 100°C.

[0032] Using the combined process parameters of this embodiment, the yield data of the glass substrate is 90.09%, and the yield data of the metal parts is 99.54%.

Embodiment 2

[0034] Heat the assembly with a heating plate, set the temperature of the heating plate to 200°C, and heat for 1 minute; disassemble the assembly, soak the glass substrate for 1 hour, and soak the soaking solution at room temperature; soak the metal parts for 6 minutes, and the soaking temperature is 90°C. Using the combined process parameters of this embodiment, the yield data of the glass substrate is 89.05%, and the yield data of the metal parts is 99.76%.

Abstract

The invention discloses a process for removing glue and reusing an assembled part. The assembled part is an assembled part composed of a glass part and a metal part. In the glue removing solution, fully soak the residual glue parts, and wipe off the residual glue after soaking; soak the metal parts in the glue removing solution heated at a constant temperature; clean and inspect the glass and metal parts, and put them into production for reuse. From the above content, it can be known that the above-mentioned glue removal process is short in time and low in cost, and will not cause damage to the electroplating film layer, ink and shape on each component, and each component after treatment can be put into production and reused directly. Therefore, the adhesive removal and reuse process of the assembly proposed by the present invention can remove the residual glue on the assembly without affecting the coating and ink.

Description

technical field [0001] The invention relates to the field of glue removal of assemblies, and more specifically, relates to a process for removing glue and reuse of assemblies. Background technique [0002] Assembled metal parts are prone to deviation, less glue, glue breakage, air bubbles, glue overflow and other phenomena during the lamination process, which will lead to the failure of the entire assembly. As far as unqualified assemblies are concerned, such as assemblies composed of glass and metal parts; processes including disassembly, deinking, flat grinding, inspection, electroplating, and assembly are usually used to reuse the assemblies and put them back into production . However, after the above process, there is still residual glue on the glass and metal parts, which affects the quality of the product, and eventually leads to the scrapping of each component, resulting in serious waste; and it is necessary to re-make the coating and ink on each component, which inc...
