Feeding rod contact pressure sensor of plate-shaped workpiece edge wrapping device

Abstract

A feeding rod contact pressure sensor of a plate-shaped workpiece edge wrapping device is composed of an inductance coil, an inner support, an internal contact pressure switch of the inner support, aninner vortex ring, an outer support, an internal touch switch of the outer support and an outer vortex ring. The inductance coil is integrally of a disc ring structure and is assembled to an inner ring of a bearing inner circle at the bottom end of a feeding telescopic rod in a sleeving winding and fastening manner. The upper end of the inner support penetrates through the top wall of a feeding suction cup, the upper top is in fastened bonding with the left part of the bottom edge of a lower port of a feeding connector, the bottom end face is in fastened bonding with an outer edge ring of theinner vortex ring and an inner edge ring of the outer vortex ring at the left side position, the internal contact pressure switch is internally arranged, and two wiring ends of a switch normally-opencontact are connected with two wiring ends of an inner vortex ring breaking joint opening correspondingly. The upper end of the outer support penetrates through the top wall of the feeding suction cup, the upper top is in fastened bonding with the right part of the bottom edge of the lower port of the feeding connector, and the bottom end face is in fastened bonding with the inner edge ring of the outer vortex ring and the outer edge ring of the inner vortex ring at the right side position. The internal touch switch is internally arranged, and two wiring ends of a switch normally-open contactare connected with two wiring ends of an outer vortex ring breaking joint opening correspondingly.

Description

technical field [0001] The invention relates to a method for wrapping the side of a flat workpiece. Background technique [0002] In many production lines of flat-shaped products, there is a process of side-wrapping flat-shaped workpieces, especially for circuit board manufacturers. This type of production process is: wrapping the entire periphery of the flat-shaped workpiece with a special adhesive tape. At present, this kind of process is all done manually, and the result is that the consistency of the wrapping state is poor, and there are defects such as partial sticking, folds, and leaks in different parts. For the usual large and heavy boards, manual operation is more difficult. This is a bottleneck that seriously affects the process of related product production lines, hindering the automation of the entire production process. Therefore, it is urgent to develop an automatic method that can ensure the consistency of the wrapping state and replace the heavy manual ope...
