Description

Technical Field

[0001] The present invention relates to the technical field of electronic component detection, repair and recycling equipment, and in particular to an electronic component shell opening machine and a method for using the same. Background Art

[0002] Nowadays, electronic components are components of electronic elements and small machines and instruments. They are often composed of several parts and can be used interchangeably in similar products. They usually refer to certain parts in industries such as electrical appliances, radio, and instrumentation. In the military, aerospace and other fields, in order to ensure the precision of their operation and minimize the influence of the external environment, electronic components are usually fixed at the bottom of a metal shell, and the metal shell is sealed by an upper cover. The upper cover and the metal shell are welded together by a weld seam formed by seam welding. During the production and use process, it is often necessary to open the shell of the electronic components sealed inside for inspection. If the electronic components are relatively expensive, they may also need to be repaired for continued use. In addition, after the equipment has been idle or scrapped for a period of time, due to the high cost of the internal electronic components, they can be recycled.

[0003] Since the electronic components are sealed inside the metal shell, when detecting, repairing and recycling the electronic components, the metal shell needs to be opened. However, when the existing shell opening machine is opening the shell, because the sealing edge of the shell is relatively thin, it will accidentally damage the electronic components and cause them to be scrapped. Moreover, during the shell opening process, debris and the like enter the inside of the shell, causing damage to the electronic components. In addition, the existing shell opening machine has low shell opening efficiency and is not universal for metal shells of different sizes. Summary of the Invention

[0018] Step 1: Select a suitable workbench according to the size of the electronic components and install it on the transfer table. If the milling length of the electronic components is similar to the length of the transfer table, the clamping mechanism can be directly installed on the transfer table; if the size of the electronic components is small, select a workbench of corresponding size, install the workbench on the transfer table, and install the clamping mechanism on the workbench.

[0058] Step 4: Input the dimensions of the electronic component 8, the thickness of the adapter table 5, the thickness of the workbench 31, the milling depth, and the distance exposed above the tabletop in the human-machine interface. According to the recorded initial positions A and B, obtain the distances of the milling cutter relative to the initial positions A and B. The control unit controls the second motor 18 and the third motor 23 to adjust the three-dimensional moving platform to a suitable position;

[0059] Step 5: Turn on the dust removal device 12, and the control unit controls the first motor 15 to work. At the same time, the milling motor 10 drives the milling cutter 14 to start working to mill the electronic component 8.
