Adhesive sticker material flatness detecting equipment

Abstract

The invention discloses adhesive sticker material flatness detecting equipment which comprises a worktable. A recessed cavity is formed in the worktable. A detection flat plate serving as a cover forthe recessed cavity is further fixed to the worktable, and a plurality of through holes which keep communicating with the recessed cavity are evenly distributed in the detection flat plate. A vacuumizing device is further connected to the recessed cavity of the worktable. A measuring device used for conducting flatness detection on an adhesive sticker material laid on the detection flat plate is mounted on the worktable. The measuring device comprises a dial indicator and a moving mechanism for driving the dial indicator to move relative to the detection flat plate. The moving mechanism comprises a longitudinal guide rail and a transverse guide rail. By adopting the structure, the adhesive sticker material flatness detecting equipment is convenient to operate and high in measuring precision.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for detecting the flatness of self-adhesive materials. Background technique [0002] At present, existing self-adhesive material flatness testing equipment generally includes a workbench, which is provided with a concave cavity, and a detection plate that forms a cover for the cavity is fixed on the workbench. A plurality of through holes communicating with the concave cavity are evenly distributed, and a vacuuming device is also connected to the concave cavity of the workbench. During detection, the self-adhesive material is spread on the detection plate, and then the cavity is vacuumed by a vacuum device. Since the detection plate is evenly distributed with several through holes that are in communication with the cavity, Therefore after vacuumizing, the self-adhesive material will be firmly adsorbed on the detection plate. After that, people determine the flatness of th...

During detection, the self-adhesive material is spread on the detection plate, and then the cavity is vacuumed by a vacuum device. Since the detection plate is evenly distributed with several through holes that are in communication with the cavity, Therefore after vacuumizing, the self-adhesive material will be firmly adsorbed on the detection plate. After that, people determine the flatness of the self-adhesive material by observing whether the self-adhesive material has a raised place, but the prior art is When it is determined that there is a raised place on the self-adhesive material, there are technical difficulties in how to measure the flatness of the raised part. Generally, it is measured manually with the help of a set square and a ruler, but because the length and width of the self-adhesive material are generally Both are large, so if you want to manually measure a certain convex point on the self-adhesive material through a set square and a ruler, it is not only inconvenient to operate, but also the measurement accuracy cannot be guaranteed.
