Automatic packing device for crystalline grains and method thereof

Abstract

The invention relates to an automatic packing device for crystalline grains and a method thereof, and especially relates to a packing device used for performing automatic detection, piling and strap packing, and the method thereof. The automatic packing device for crystalline grains uses an automated machine in replace of detecting crystalline grains with bare eyes and operations such as manually performed cover materials placement, charging tray piling, upper cover placemeng and strap packing, therefore obtaining aims of saving manpower cost, increasing output and efficiency of packing, preventing careless mistakes or loss caused by human operation, etc.

Description

technical field [0001] The present invention relates to an automatic packaging device and method for crystal grains, in particular to a packaging device and method for automatic detection, stacking and tape packaging of trays loaded with crystal grains. Background technique [0002] In the integrated circuit manufacturing process, after the integrated circuits on the wafer are manufactured, after testing and cutting the die, they are usually classified according to the test results, and the die of the same grade are removed from the wafer and placed In trays, that is, the grains in each tray are of the same grade. These trays containing the same grade of die will be handed over to the line operator for subsequent inspection and strapping operations. [0003] However, these follow-up inspections and tape packaging operations usually require the online operator to visually inspect each die holding groove in each tray to see if there are die placed upside down, die overturned,...

AI Technical Summary

Problems solved by technology

Therefore, for online operators, it is still very difficult and strenuous to visually inspect extremely small dies, even with a large square mirror. Not only is it difficult to see clearly where the dies are placed in the tray state, and it is very easy to ignore the abnormality of die placement or the situation of missed inspection

In addition, the use of eyes for a long time to inspect small crystal grains will easily make the eyes of the line operator tired, and they need to rest before continuing. Therefore, the detection efficiency is often poor.

[0006] (2) Secondly, since the strapping operation needs to be carried out manually by the online operator, not only does it result in a large demand for manpower, but also the efficiency of the operation is relatively low, which easily leads to insufficient output and production capacity.

[0007] (3) In addition, the belt packaging operation is carried out manually, and the objects operated are small-sized items such as crystal grains and trays, which are easy to be ignored, overturned and damaged. Overturned or damaged due to personnel negligence
