Problems solved by technology

The feeding mechanism of the existing testing equipment still adopts the straight cylinder double material clamp, the cross transposition method, and the material is ejected from the bottom to the top by the ejector rod. In actual use, the material is shifted and moved.
Moreover, the height of the automatic movement mechanism for placing solar cells (hereinafter referred to as cells or cell templates) is not adjustable, including metal limit fixtures, which are likely to cause damage to solar cell glass substrate products, resulting in a defect rate of more than 80% in appearance.
The protection of the light source of the light box is not enough, it is not easy to adjust, resulting in inaccurate product test performance

Embodiment 2

[0043] image 3 It is the figure of this embodiment

[0044] The bin box 207 is mainly composed of a slideway plate 207-1, an upper baffle plate 207-2 and a lower connecting plate 207-3. The slideway plate 207-1 is an arc-shaped slideway, and the two sides of the slideway plate 207-1 are installed The upper baffle plate 207-2 forms a groove shape with the slideway plate 207-1. There is a light-transmitting hole 207-4 on the side of the upper baffle plate 207-2, and the light is transmitted from one side of the bin box 207 to the other. On the side, the lower connecting plate 207-3 is installed on the blanking opening of the slideway plate 207-1, and the lower connecting plate 207-3 is processed with a fixed connection hole 207-5 with the base 208.

Embodiment 3

[0046] Figure 4 In the figure of this embodiment, the structure of the tongue-type slider 206 is T-shaped, the tongue is a large head, the width and thickness are greater than the tongue waist and the root of the tongue, and there is a carrier hole 206-1 for placing materials at the tongue head. Slide rails 205 are installed on both sides of the waist, and there are elongated motor shaft through holes 206-4 above the waist. The motor shaft stretches out from the waist through hole 206-4 of the tongue-type slider 206. The motor shaft is fixed and the tongue-type slider 206 moves back and forth along the motor shaft, the length of the strip-shaped through hole 206-4 should ensure the stroke length of the feeding position and the blanking position, and a fixed eccentric wheel stop post 211 is installed between the through hole 206-4 and the root of the tongue There is a mounting hole 206-5 in the base of the tongue, a fixing hole 206-6 for fixing the moving stroke plate 212.

Embodiment 4

[0048] See Figure 13 , compared with Embodiment 1, the present embodiment adds a set of I-level qualified product automatic swing film mechanism 8 and rubber disc automatic moving mechanism 9 at the fifth jig 4'07 position of turntable 4'02, because I-level qualified product Products account for more than 80% of the entire test cell, and the automatic swing mechanism 8 of Class I qualified products has the longest swing time, which is equivalent to more than twice that of other mechanisms. Therefore, after adding the mechanism, the turntable 4'02 can be improved. The speed of rotation improves the overall production efficiency, which is equivalent to increasing the speed by 40%, and the efficiency is greatly improved.

Abstract

The invention discloses an automatic test device of testing weak light type solar cells, and belongs to the technical field of solar manufacture equipment. The main technical characteristics of the invention are that an automatic charging mechanism includes a tongue type linkage channel mechanism formed by a pedestal and a bunker box, an automatic transmission mechanism transmits solar cells to stations, an automatic test mechanism tests the solar cells, and a classification automatic wobble plate mechanism puts the solar cells on an automatic mobile mechanism. The beneficial effects of the invention are that the overall running speed of a machine is substantially increased, the machine can reliably and steadily function for a long period of time, the noise is minimized, and a product appearance qualified rate reaches above 90%.

Description

technical field [0001] The invention discloses an automatic testing device for weak-light solar cells, which belongs to the technical field of solar energy manufacturing equipment. Background technique [0002] At present, the traditional method of measuring solar cells is manual, which is time-consuming and labor-intensive, and is highly dependent. It is easy to cause defective products due to personnel negligence and other reasons. Labor costs continue to increase and recruitment is more difficult. In this environment, in order to improve work efficiency and save labor costs, the solar energy manufacturing industry has increased research and development efforts. The company has developed a second generation that is more beautiful and tidy than the first generation. . Due to the difference in the characteristics of low-light solar cells and strong-light solar cells, special testing equipment has been researched and developed. The feeding mechanism of the existing testing ...
