Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a hot plate welding device. Background Technology

[0002] Currently, such as Figures 1-3 The assembly of the upper and lower plastic shells shown still relies entirely on manual dispensing and manual assembly: the operator holds a glue gun in the left hand and grabs the shell with the right hand, and squeezes out a continuous or segmented hot melt glue / instant glue at the root of the stop based on experience; then the operator quickly aligns and presses the upper and lower shells together with both hands, and after judging by subjective feeling that "it is almost pressed", it is placed in a simple fixture to wait for room temperature air drying. This seemingly simple action has a series of defects: 1) Due to fluctuations in glue gun air pressure, batch differences in glue viscosity, and inconsistent manual pressing time, the amount of glue is sometimes excessive and sometimes insufficient; excess glue is squeezed onto the surface at the moment of shell assembly, forming irregular "earthworm-like" residue, which not only covers the parting line but also attracts dust; while insufficient glue results in glue breaks and voids, leaving hidden dangers for subsequent air leakage; 2) Manual shell assembly lacks guidance and limits, relying solely on visual alignment of the stop; the injection molded part itself has warping deformation, and under uneven stress, some parts are over-compressed while others are not compacted, resulting in a "wavy" distribution of gaps around the perimeter; the assembled shell is "transparent" under light, becoming a "must-do" item for appearance inspection; 3) The glue needs to dry afterward, affecting assembly efficiency and requiring sealing tests, resulting in a high and unstable defect rate, seriously leading to problems such as product appearance, air leakage, and glue overflow.
