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 glue removing and reusing process for an assembling part. The assembling part is formed by a glass piece and a metal piece. The glue removing and reusing process comprises the following steps of, disassembling all components of the assembling part by adopting a constant-temperature heating plate; placing the glass piece in a glue removing solution to fully soak a residualglue part, and wiping the residual glue after soaking; soaking the metal piece in a constant-temperature heated liquid removing liquid; and cleaning and inspecting the glass piece and the metal piece, and putting into production for reuse. According to the glue removing process, the glue removing process is short in time and low in cost, a plated film layer, ink and appearance on each component cannot be damaged, and the processed components can be directly put into production and reused. Therefore, the glue removing and reusing process for the assembling part can remove residual glue on theassembling part on the premise of not affecting the plated film and the 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...
