Angle in-place device of turnover mechanism

Abstract

The invention discloses an angle in-place device of a turnover mechanism. A disc-shaped piece capable of synchronously rotating along turnover sheets is arranged on a rotation shaft, grooves corresponding to the turnover sheets one by one and arranged along the circumferential direction at intervals are arranged on the disc-shaped piece, a sensor is adopted to detect rotation states of the grooves, after the front face of a battery sheet is completely printed, the battery sheet is transmitted to a group of turnover sheets from the turnover mechanism and turns over along rotation of the rotation shaft, the sensor detects the rotation states of the corresponding grooves, when the battery sheet rotates 180 degrees, and signals are sent to the controller which receives the signals and stops amotor to continuously rotate, so that the turnover battery sheet is transmitted from the other side of the turnover mechanism to conduct reverse side printing. Therefore, the battery sheet can accurately turn over 180 degrees along the turnover mechanism, and probability of damage of the battery sheet caused by rotation errors caused when the solar battery sheet is turned over by the turnover mechanism is reduced.

Description

[0001] technical field [0002] The invention relates to an angle setting device of a turning mechanism. [0003] Background technique [0004] The positive and negative electrodes of the printed solar cells are respectively distributed on the front and back of the cells. When printing the solar cells, after printing one side, the cells need to be turned over 180° and then printed on the reverse side. The traditional production method of manually turning over the cells is inefficient. Usually, the cells are turned over by a turning mechanism in production, that is, multiple sets of turning pieces are set on the turning shaft, and each set of turning pieces is composed of multiple Composed of sheet rods, a cavity capable of accommodating battery slices is formed between multiple sheet rods. The transmission mechanism transfers each battery sheet from one side to the cavity of the flipping sheet. As the flipping shaft rotates, the flipping sheet The rotation drives the cell...

The traditional production method of manually turning over the cells is inefficient. Usually, the cells are turned over by a turning mechanism in production, that is, multiple sets of turning pieces are set on the turning shaft, and each set of turning pieces is composed of multiple Composed of sheet rods, a cavity capable of accommodating battery slices is formed between multiple sheet rods. The transmission mechanism transfers each battery sheet from one side to the cavity of the flipping sheet. As the flipping shaft rotates, the flipping sheet The rotation drives the cell to flip, so as to realize the flip of the cell by 180°

However, the solar cells are made of high-purity silicon with a thickness of about 0.2 mm. The material is very brittle and easily broken. If there is an error in the rotation angle of the flip axis, the cells will be broken
