Problems solved by technology

Since it is necessary to realize the forward and reverse transmission of the paper roll, the ordinary conveyor belt mechanism can no longer be realized, and the forward and reverse transmission of the paper roll realized by the dual motors is very easy to cause jamming and paper breakage in the actual application process , because it is impossible for the two motors to achieve true synchronization. In the case of one fast and one slow, either the paper feeding will cause the machine to be stuck, or the paper will be broken

Embodiment 1

[0028] like figure 1 , 2 As shown, the transmission device of this embodiment includes a single motor transmission mechanism capable of forward and reverse rotation, a roll paper 1, two roll paper shafts 2 for installing the roll paper 1, and a roll paper shaft synchronous wheel 21. The two ends of the paper roll 1 are respectively wound on the two paper roll shafts 2; the single motor transmission mechanism includes the drive shaft 4 and its driving synchronous wheel 41 and two The driven shaft 5 and its driven synchronous wheel 51 are respectively installed on the two clutches 7 on the driven synchronous wheel 51 . The paper reel shaft synchronous wheel 21 is connected with the driven synchronous wheel 51 through the synchronous belt 6 and rotates accordingly. The distance traveled in each direction is equal. Each set of driven shafts 5 and their driven synchronous wheels 51 includes two driven shafts 5 and two driven synchronous wheels 51 respectively sleeved on the ends...

Embodiment 2

[0033] The conveying method of this embodiment adopts the conveying device as in the above-mentioned embodiment 1, including: Step 1, passing the paper through the conveying device, and conveying the solar cells to the predetermined station; Step 2, after the process of the predetermined station is completed , the solar battery sheet is sent out from the printing station through the conveying device, rewinding in the opposite direction and the same distance as in the previous step. After the rewinding action, it is determined whether the roll paper is abnormal. If the roll paper is abnormal, the rewinding action is repeated once; if the roll paper is normal, the above paper feeding action is repeated. The above-mentioned action of determining whether the roll paper is abnormal is performed once after each rewinding action.

Abstract

The invention relates to transmitting method and device of a solar battery slice. The device comprises a single-motor transmission mechanism, roll paper and two roll paper shafts, wherein the single-motor transmission mechanism can rotate in a forward direction and a reverse direction; the roll paper shafts are used for installing the roll paper; the two roll paper shafts are connected with a transmission shaft of the transmission mechanism and rotate along with the transmission shaft, both ends of the roll paper are respectively rolled on the two roll paper shaft, and in the two neighboring rotations of the transmission mechanism, the distances of the roll paper walking in the forward direction and the reverse direction are equal. By adopting the device and method, an electric motor can realize forward and reverse-direction paper feeding so that the roll paper can be repeatedly utilized for a long term, and the problems of paper blockage or paper breakage and the like are avoided.

Description

technical field [0001] The invention relates to the manufacture of solar cells, in particular to a method and device for transferring monocrystalline silicon / polycrystalline silicon solar cells. Background technique [0002] In the motor printing of the cell, it is the process of printing silver lines on the silicon wafer with silver paste through the printing screen. During the printing process, the silver paste will often spill to places other than the cell. After the slurry dries up, when it is printed again, it will cause the chip to be broken and scrapped. In order to prevent the spilled silver paste from contaminating the printing table and causing fragments of the battery sheet, the usual practice is to cover the work table with a layer of paper, so that when the silver paste is spilled on the paper, the sticker can be replaced at any time to avoid damage. Fragments, because the way of stickers needs to be completed manually, it is also possible to stop the work of t...
