Device for detecting thickness of foam material sheet and rejecting defective foam material sheet

Abstract

The invention discloses a device for detecting the thickness of a foam material sheet and rejecting a defective foam material sheet. The device comprises a base station, two thickness detection assemblies and a rejecter, a rectangular material rejecting hole is formed in the right end of a datum plate of the base station, a color code sensor is positioned right above a material belt, thickness sensors of the thickness detection assemblies are installed at the moving end of a three-way adjusting table, a three-axis adjusting seat of the rejecter is installed on the rear side of the material rejecting hole, a micro-motion air cylinder is connected with the rotating end of the three-axis adjusting seat, the micro-motion air cylinder is obliquely located above the left end of the material rejecting hole, the material belt moves on the datum plate from left to right, the two thickness sensors detect thickness information of the two sides of the material sheet respectively, whether the material sheet is a defective product or not is judged, the material belt penetrates through the material rejecting hole from top to bottom, a lower bottom film is stripped from the material belt through astripping knife, and the micro-motion air cylinder applies pressure to strip the defective material sheet from the material belt. The device has the effects of automatically detecting the thickness of a product, rejecting defective products, and being high in speed and precision.

Description

technical field [0001] The invention relates to the field of 3C sheet detection, in particular to a device for detecting the thickness of a foam sheet and removing defects. Background technique [0002] In the production of 3C products, it involves a large number of flake thickness inspections such as foam and removal of defective products. At present, manual visual inspection and manual removal of defective products are used. The defects are: first, the speed is slow and the efficiency is low. It consumes a lot of manpower, and it is difficult to apply to large-scale continuous production; second, manual inspection, there are human factors such as human fatigue or lack of experience, resulting in bad products mixed into the finished product, manual removal, easy to damage the tape or similar good products, good products rate decreased. Contents of the invention [0003] In order to solve one or more of the above problems, the present invention provides a device for detec...
