AI Technical Summary

Problems solved by technology

[0004] (1) The grinding operation must rely on the operator's experience to determine the amount of grinding. Therefore, in order to avoid excessive grinding and damage to the electronic device, the operator often stops the grinding and uses a microscope or image detector to determine whether it has been ground. to the appropriate position (observation part), if the observation part is not ground, continue grinding, it is difficult for the operator to reproduce the grinding position for grinding, resulting in irregular product cross-section, the grinding process is quite time-consuming, and the reproducibility is not good good
[0005] (2) If the operator grinds the electronic device too much, or creates multiple grinding surfaces, the required section position cannot be accurately observed

Embodiment Construction

[0020] Such as Figure 1 to Figure 9 As shown, it can be clearly seen from the figure that the present invention includes a grinding device 1, a transfer device 2, a control device 3 and a testing device 4, wherein:

[0021] The grinding device 1 comprises a coarse grinding disc 11, a fine grinding disc 12 and a wiper 13. The coarse grinding disc 11 can be ground to be grinded because its surface roughness (arithmetic average roughness Ra or ten-point average roughness Rz) is relatively large. Fast grinding, but the grinding accuracy is relatively poor, and the fine grinding disc 12 has a relatively low grinding speed for the object to be ground due to its small surface roughness, but the grinding accuracy is better.

[0022] The transfer device 2 includes a support arm 21 and a displacer 22. One end of the support arm 21 is connected to the displacer 22. The displacer 22 is used to drive the support arm 21 to rotate and move up and down. The support arm 21 is located at the o...

Abstract

The invention relates to a semi-automatic metallographic grinder which comprises a grinding device, a transferring device and a control device. When the semi-automatic metallographic grinder carries out grinding operation, the control device controls the transferring device to clamp an object to be ground, and the object to be groundis roughly ground and finely ground in sequence on the grinding device. By the way, the object to be groundis ground in an automated way, so that the grinding operation is accelerated; the reappearance degree is increased, the reject ratio is reduced, and the grinding cost is reduced.

Description

technical field [0001] A semi-automatic metallographic grinding machine, especially a semi-automatic metallographic grinding machine capable of rough grinding and fine grinding, and capable of automatic grinding operations. Background technique [0002] Most of the electronic devices in electronic products are composed of various parts arranged on the circuit board. In order to operate correctly, the various parts and the circuit board must be positioned correctly with each other. The correct electrical connection between the parts and the circuit board must use conductive patterns To form, in order to check whether the parts and the circuit board are electrically connected correctly, you can observe the transverse section to check the problems that may lead to poor products, such as: the appearance of soldering and solder joint voids, layer separation (detachment or peeling of layers) )Wait. [0003] Existing inspection methods for electronic devices are cutting with metal...
