Hinge Structure of Feeding Belt Mechanism of Hemming Device for Plate-Shaped Workpiece

Abstract

A hinge structure of a belt feeding mechanism of a plate-shaped workpiece hemming device is composed of a rocker arm, an elastic arm, a connecting arm, an adjusting handle, a movable hinge shaft, a connecting rod, a rocker shaft and a base hinge shaft. The tail end of the rocker arm is equipped with a spring arm and a connecting arm. The head end of the connecting arm is hingedly assembled on the tail end of the rocker arm through the adjusting handle and the rocker structure. The right end of the flexible arm extends from the connecting arm and is hinged with the tail end of the connecting rod through the movable hinge shaft. The lower end of the rocker shaft is provided with a supporting cap structure to support the connecting arm, the lower section is provided with a column to support and lock the rocker arm, and the upper end is sleeved with an external thread to cooperate with the internal thread of the adjusting handle; manually screw the adjusting handle The state of cooperation between the rocker arm hinged by the loosening or locking rocker shaft and the elastic arm can be adjusted, but the loose fit with the connecting arm is maintained. The first end of the connecting rod forms a rotational fit with the base hinge shaft with its bushing hole, and the tail end forms a rotational fit with its bushing hole and the movable hinge shaft. The base hinge shaft and the shaft sleeve hole at the head end of the connecting rod form a rotational fit. The upper end of the movable hinge shaft is provided with a clamping structure and the lower end is equipped with a clamping pin structure.

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...
