The material taking assembly 100 and the transfer device comprising the material taking assembly 100 of the following embodiments can solve the above technical problems.

Referring to fig. 2 to 5, fig. 2 is a front view of an embodiment of a grasping element according to the present application, fig. 3 is a left side view of the grasping element shown in fig. 2, fig. 4 is a sectional view taken along a line a-a of fig. 3, and fig. 5 is an enlarged view of a partial structure of fig. 4.

The take-off assembly 100 is adapted to selectively grasp or release products. The product may be the spring 3 described above, but is not limited to the spring 3.

In the illustrated embodiment, the magnets are designated as a first magnet 10 and a second magnet 12 for ease of distinction. The number of the first magnets 10 is two, and the two first magnets 10 are embedded in the magnetic conduction member 4. The second magnet 12 is sleeved outside the magnetic conduction member 4. The first magnet 10 and the second magnet 12 may be permanent magnets.

In an application scenario, after the material taking assembly 100 grabs a product, it is difficult to ensure that the product is in a predetermined posture on the material taking assembly 100, so that when the product is placed, the placing accuracy cannot be ensured.

To improve this, in some embodiments the second portion 7 of the magnetically permeable member 4 extends from the first portion 5 in a first direction for insertion into a product. The second portion 7 is located to the product cover, can guarantee that the product is in predetermined gesture on getting material subassembly 100.
