Abstract
Disclosed is a device for chain-type texturing and fragmentation rate reducing of polycrystalline solar cell. Transmission rollers and stop rollers are split and the stop rollers allow the forced direction of silicon chips in favor of the centering transmission of the silicon chips. The stop rollers are arranged on the direction vertical to the transmission direction of the silicon chips, which freely rotate around the axial line thereof. The silicon chips touch the rollers to produce the friction force which allows the rollers to rotate around the axial line thereof and allows the silicon chips to move towards the center line of the transmission. As the stop rollers are arranged at both sides of the silicon chips, the silicon chips whether touch the stop rollers at any one side will move towards the center line of the transmission to automatically rectify a deviation. The utility model has the beneficial effect of changing the original scheme of the integral design between the transmission rollers and the stop rollers, eliminating the alteration shearing force between the stop rollers and the silicon chips, reducing the inducement of the silicon chips broken and lowering the fragmentation rate within 2 per thousand.
Description
Technical field
The utility model relates to a kind of device of reducing fragmentation rate by chain type texturing of multicrystalline solar cells, is the transfer scheme of silicon chip in the chain type texturing technology of multicrystalline solar cells, belongs to the processing and manufacturing field of solar battery sheet.
Background technology
The transfer scheme of silicon chip in the chain type texturing technology of existing multicrystalline solar cells adopts the directly transmission of alignment restrictions silicon chip on the roller, because the defective of mechanism, silicon chip regularly is subjected to alternating shear power in the process that transmits; Because long-term work, serious wear causes the increase of shearing force, strengthens the fragment rate of silicon chip.
Summary of the invention
In order to overcome the deficiency of prior art structure, the utility model provides a kind of device of reducing fragmentation rate by chain type texturing of multicrystalline solar cells, has well solved this problem.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of method of reducing fragmentation rate by chain type texturing of multicrystalline solar cells, live roller and spacing roller split design, the design of spacing roller makes silicon chip be subjected to force direction to help the transmission placed in the middle of silicon chip;
Arrange spacing roller on the direction vertical with the silicon chip direction of transfer, this spacing roller rotates freely around the axis of oneself,
When silicon chip is run into roller, the frictional force that produces makes the axis rotation of roller around oneself, and silicon chip is moved to the centerline direction that transmits, because the both sides of silicon chip all are furnished with spacing roller, no matter silicon chip is run into the spacing roller of either side like this, the capital produces to the moving of center conveyor line direction silicon chip, plays the effect of automatic deviation correction;
Simultaneously,, can not produce the power of shearing, reduce the fragment rate of silicon chip greatly silicon chip because the stress point that silicon chip edge contacts with circular roller has only a bit.
A kind of device of reducing fragmentation rate by chain type texturing of multicrystalline solar cells, the structure of split type spacing roller is:
Roller is made of three parts: a supporting bracket, a hold-down screw, a roller body;
Wherein, supporting bracket is used for the whole spacing roller of support fixation; Hold-down screw is limited to the roller body on the supporting bracket, it can only be rotated around the axis of oneself, and axial moving can not be arranged;
Roller body and mutual vertical contact of silicon chip are rotated around the axis of oneself by rubbing action; Upper pressure wheel links to each other by transmission mechanism with delivery roller, relatively rotation, silicon chip upper pressure wheel and delivery roller between the two frictionally travel forward.
A kind of device of reducing fragmentation rate by chain type texturing of multicrystalline solar cells is characterized in that upper pressure wheel links to each other by transmission mechanism with delivery roller, relatively rotation, silicon chip upper pressure wheel and delivery roller between the two frictionally travel forward; Spacing roller reaches with upper pressure wheel and does not contact with delivery roller, it is mechanism independently, when silicon chip when upper pressure wheel and delivery roller travel forward between the two, in case depart from the direction of transmission, spacing roller will be run in the edge of silicon chip, servo-actuated rotation by spacing roller makes silicon chip to middle transmission, plays the function from the dynamic(al) correction direction of transfer.
The beneficial effects of the utility model: change the conveying roller and the limited roller integrated design of original scheme, remove the fricative alternating shear power of limited roller and silicon chip, reduce the inducement of silicon chip fragment, fragment rate is reduced in 2 ‰.

Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment
Embodiment 1: as shown in Figure 3, the scheme stress point that the utility model adopts is few, and the stressed Wafer that more helps transmits between two parties, carries out the gap adjustment easilier, and handling ease.
A kind of method of reducing fragmentation rate by chain type texturing of multicrystalline solar cells is arranged spacing roller on the direction vertical with the silicon chip direction of transfer, this spacing roller can rotate freely around the axis of oneself,
When silicon chip is run into roller, the frictional force that produces makes the axis rotation of roller around oneself, and silicon chip is moved to the centerline direction that transmits, because the both sides of silicon chip all are furnished with spacing roller, no matter silicon chip is run into the spacing roller of either side like this, the capital produces to the moving of center conveyor line direction silicon chip, plays the effect of automatic deviation correction
Simultaneously,, can not produce the power of shearing, reduce the fragment rate of silicon chip greatly silicon chip because the stress point that silicon chip edge contacts with circular roller has only a bit.
A kind of device of reducing fragmentation rate by chain type texturing of multicrystalline solar cells, as shown in Figure 3, upper pressure wheel 5, spacing roller 6, silicon chip 3, delivery roller 7; Among Fig. 3: upper pressure wheel 5 and delivery roller 7 link to each other by transmission mechanism, rotation relatively, silicon chip 3 upper pressure wheel 5 and delivery roller 7 between the two frictionally travel forward; Spacing roller 6 reaches with upper pressure wheel 5 and does not contact with delivery roller 7, it is mechanism independently, when silicon chip 3 when upper pressure wheel 5 and delivery roller 7 travel forward between the two, in case depart from the direction of transmission, spacing roller 6 will be run in the edge of silicon chip 3, servo-actuated rotation by spacing roller 6 makes silicon chip 3 to middle transmission, plays the function from the dynamic(al) correction direction of transfer.
