Problems solved by technology
In the field of semiconductor solder pin processing, the traditional technology is manual loading and unloading of PIN pins. With the aid of a microscope, the tip of the PIN pin enters the hole of about 30 μm on the solder pin, which requires a high degree of proficiency of the operator and low efficiency. Labor costs remain high

An automatic loading and unloading and hole-feeding mechanism for PIN needles used in grinding machines, including a PIN needle storage assembly for storing and providing PIN needles, one side of the PIN needle storage assembly is connected with a PIN needle delivery assembly matched with it, and the PIN needle storage assembly The other side of the drive assembly is connected to the drive assembly, and the rotary assembly is installed on the back of the drive assembly. The drive assembly converts the horizontally arranged PIN pins into vertical ones, and corresponds to the inner holes of the solder pins to be processed. This method can store PIN needles in batches by setting up the PIN needle storage assembly, which is convenient for fast and automatic feeding, and is easy to realize automation. The push process of PIN needles is completed continuously through the ejector rod and multiple guide grooves, and the automatic up and down of PIN needles is completed with the driving component. material, save processing space, fast and accurate positioning of the PIN needle can be achieved through the guide plate and blowing pipe, and the loading and unloading route of the PIN needle can be fixed and controllable through the limit block, limit device and guide groove, so that the production process is stable and efficient .
Description
technical field [0001] The invention relates to the technical field of grinding machines, in particular to an automatic loading and unloading and hole-feeding mechanism with PIN needles for grinding machines. Background technique [0002] The diameter and angle of the inner chamfer (IC, Inside Chamfer) of the solder pin directly affect the size and shape of the solder joint when the semiconductor chip is packaged. As a key tool for chamfering the inner hole of the solder pin, the PIN pin is pre-ground on the grinding machine for the angle and diameter according to the needs of solder pin processing. During automatic IC processing, on average, 2 to 3 PIN pins are used for processing one solder pin, so the speed and accuracy of the automatic loading and unloading of PIN pins and automatic hole entry will directly affect the efficiency and accuracy of IC processing. In the field of semiconductor solder pin processing, the traditional technology is manual loading and unloading ...
