Adhesive sticker material flatness detector with local detection function

Abstract

The invention discloses an adhesive sticker material flatness detector with a local detection function. The adhesive sticker material flatness detector comprises a worktable. A recessed cavity is formed in the worktable. A detection flat plate is arranged on the recessed cavity, and a plurality of through holes are evenly distributed in the detection flat plate. A vacuumizing device is connected to the lower portion of the recessed cavity. A measuring device for conducting flatness detection on an adhesive sticker material relatively laid on the detection flat plate is arranged on the worktable. The measuring device comprises an overall measuring device and a local detecting device. The overall measuring device comprises a dial indicator and a moving mechanism for driving the dial indicator to move. The moving mechanism comprises a longitudinal sliding rail and a transverse sliding rail. The local detecting device comprises a rotating mechanism for driving the dial indicator to rotate,and the rotating mechanism comprises a rotating disc. A radial sliding groove is formed in the rotating disc, and a sliding block is arranged on the radial sliding groove. By adopting the structure,the adhesive sticker material flatness detector is convenient to operate, high in measuring precision and suitable for overall detection and local detection.

Description

technical field [0001] The invention relates to a detector for the flatness of self-adhesive materials, in particular to a detector for the flatness of self-adhesive materials with partial detection. Background technique [0002] At present, existing self-adhesive material flatness testing instruments generally include a workbench, which is provided with a concave cavity, and is also fixed with a detection plate that forms a cover for the cavity 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 pl...

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.
