Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 Shown is a loading and unloading device for loading and unloading solar cells in a quartz boat, which includes a silicon wafer slice regularization mechanism 2, a silicon wafer lifting mechanism 3, a quartz boat entry and exit mechanism 4, and six A shaft manipulator 5 and a suction cup assembly 6 arranged at the end of the six-axis manipulator 5 .

[0029] The silicon chip splitting and regularizing mechanism 2, the silicon wafer lifting mechanism 3 and the quartz boat in and out mechanism 4 are arranged on the same working table 1 to form a silicon wafer lifting and splitting mechanism, wherein the upper end of the working table 1 is fixed with silicon Slice and slice regularization mechanism 2 and quartz boat in a...

Abstract

The invention relates to a loading/unloading device used for loading and unloading a solar cell sheet in a quartz boat. The device comprises a work table, a silicon chip lift slicing mechanism arranged on the work table, a mechanical hand and a suction cup assembly arranged on the end part of the mechanical hand. The silicon chip lift slicing mechanism comprises a silicon chip slicing normalizing mechanism, a silicon chip lift mechanism and a quartz boat entry-exit mechanism. According to the invention, 2.38mm-spaced silicon chips in the half-space quartz boat with 200 slots are gripped and transferred in two times through the silicon chip slicing normalizing mechanism; each time of spacing, 100 chips are gripped; through the silicon chip slicing normalizing mechanism, the dense silicon chips in the half-space quartz boat with 200 slots are separated into large-spaced silicon chip groups, which is convenient for the gripping of the suction cup assembly; the device has the advantages of high work efficiency and high automation degree; the work intensity of workers is reduced; and the breakage rate of the silicon chips is effectively reduced.

Description

technical field [0001] The invention relates to a production and processing mechanical equipment of solar cells, in particular to a loading and unloading device for loading and unloading solar cells in a quartz boat. Background technique [0002] During the processing of solar cells, in the process of annealing and diffusion, it is necessary to load and remove the cells into and out of the quartz boat. Most of the quartz boats used in the current process are half-pitch quartz boats with 200 slots, and the slot pitch is only 2.38mm. The annealing process is one piece per groove, and the diffusion process is two pieces per groove. Cells (silicon wafers) are dense, manual picking and placing is labor-intensive, and the waste rate is high. The manipulator designed by our company for the above situation has applied for a patent, and the name is a manipulator for solar cell rotating basket and its double-head transfer device. It can automatically and efficiently pick and place ...
