Embodiment 1
[0054]
[0055] As is known knowledge, ceramic bases with Kovar rings are magnetic, while ceramic bases without Kovar rings are non-magnetic. However, the team of inventors discovered that the ceramic base without a kovar ring also has weak magnetism, which is a phenomenon that has not been discovered before and is unknown knowledge.
[0056]
[0057] On the basis of the aforementioned knowledge, the team of inventors thought that "we can use the weak magnetism found in the ceramic base without kovarable rings to cleverly design and utilize this weak magnetism to design a set of flip transfer fixtures".
[0058] In order to achieve the above goals, the team of inventors has carried out several researches. After retrieval: CN 210655231 U has proposed a magnetic product flip fixture, which uses: a groove is set in the magnetic suction plate to put the magnet, and then the magnetic suction plate and the The positioning plate is socketed, and the through holes on the positioni...
